ZOOLOGIA.

Class INSECTA.

Order COLEOPTERA.

Tribe HETEROMERA (continued).

Fam, LAGRITIDA.

The bulk of the Central-American representatives of this family belong to one genus,

Statira ; a few are referable to Colparthrum ; and for the remainder several new genera

are required. These latter are chiefly based upon the structure of the mandibles and

labial palpi, characters first noticed by Kirsch in the genus Colparthrum: in one, Epi-

cydes, the antenne have a very short third joint; and in Othryades (as in Colparthrum)

the metasternal episterna have a narrow, deep, and well-defined groove along the inner

and anterior margins, a character apparently of generic value in this family. Stzlpno-

notus * (= Calophthalmus, Th.) is also here included in the Lagriide; this genus was

referred by Thomson to Group III. of the “'Ténébrionides vrais” of Lacordaire and

stated to be allied to Boros}. It has, however, very strongly exserted and subcon-

tiguous anterior cox, thus differing from the Tenebrionide; it agrees, in fact, in this

respect with the Old-World genus Lagria, though possessing a very different facies.

In Stilpnonotus, as in the other genera here included in this family, the anterior

coxal cavities are closed behind.

The genera represented in our fauna may be tabulated thus :—

Anterior cox moderately exserted, not contiguous, the prosternum raised

between them ; epistoma separated from the front by a deep groove ;

antennary orbits prominent.

Antenne not gradually thickening from the base to the apex; the apical

joint long, or at least as long as joints 9 and 10 united.

Apical joint of the labial palpi narrow and ovate; mandibles simply

unidentate or feebly bifid at the apex.

Intermediate joints of the antenne normal . . . . . . - Statira.

Intermediate joints of the antenn flattened, 6 and 7 the widest. Uroplatopsis. ~ § %

* In Gemminger and Harold’s Catalogue, vii. p. 1999, this generic name is erroneously sunk as a synonym

of Eurypus, Kirby; the latter has the anterior coxal cavities widely open behind.

+ In Boros (a genus included in the Pythide by Leconte and Horn) the anterior coxal cavities are also

open behind.

Statira apparently replaces Lagria in the New World ; and its species are still more

fragile. ‘The North-American genus Arthromacra and the Tropical-South-American

genera Emydodes, Barsenis, and Disema are not represented within the limits of our

fauna*. Two other genera from Tropical South America have been referred to the

Lagriide: one of these, Storthephora, Makl., is congeneric with Paratenetus, Spin.

(cf. Biol. Centr. -Amer., Col. iv. pt. 1, p. 238), a genus considered by recent authors to

belong to the Group ‘ Hetsiotanides’ of the Tenebrionide, the author including in it

two species of small size (one from Venezuela and one from Brazil)}; the other,

Acropachia, Makl., doubtless belongs to the same group.

Very many Central-American species of Lagriide closely resemble those of widely

separated families; one genus, Uroplatopsis, has quite the facies of certain genera of

Hispide, and some of its species (all of which are apparently very rare) possess very

remarkable sexual characters. So far as we have been able to ascertain, the secondary

sexual organs of the male do not afford (except in some few species) good corroborative

specific characters.

* During the past month two additional genera from South America have been described by Fairmaire

(Compt. Rend. Ann. Soc. Ent. Belg. xxxiii. p. xlix): one of these, Stpolisia, agrees in many of its characters

with Disema.

+ These are closely allied to P. denticulatus (cf. Biol. Centr.-Am., Col. iv. pt. 1, p. 243, t. 10, fig. 26).

STATIRA. a

STATIRA.

Statira, Lepeletier de St.-Fargeau & Serville, Encycl. méthod. x. p. 479 (1825) ; Lacordaire, Gen.

Col. v. p. 571.

Ninety-five species of this genus have been described, and probably almost as many

again exist unnamed in collections. Statira is perhaps the most characteristic genus

of Heteromera in Tropical America, and an immense number of species no doubt exist

there, each limited area possessing numerous representatives. The genus ranges from

the Middle United States to the Argentine Republic; but its members become much

fewer in number northwards, six only being known from north of our northern

boundary. From Central America we have now to record no less than eighty species,

three or four only of which are at all widely distributed within this area; and one only

of the total number is known to us from south of our region. Two species from

the warmer parts of the Old World have also been referred to Statira*. Some of the

Central-American representatives bear a close resenvblance to various forms of Carabide

inhabiting the same districts, notably to certain species of Agra, Colpodes, Calleida,

Euproctus, Dromius, and Leptotrachelus ; others from Tropical South America resemble

Casnonia. Maklin is the only author who appears to have paid very much attention to

the Tropical-American Statire ; but he appears to have chiefly confined himself to the

species of Brazil, Colombia, and Mexico, most of those catalogued from these countries

having been described (and some of those of the older authors redescribed) by him. It

must be remarked that in numerous cases this author has, probably from insufficiency

of material, placed far too much importance upon colour as a specific character ; and in

the descriptions of three of his Mexican species (two of which, S. decorata and S. cyani-

pennis, are here referred to other genera) no mention whatever is made of their more

important structural characters, though the colour is given at great length. Examples

found under bark, often not fully mature, are sometimes, as might be expected, lighter

in colour than those found upon herbage; and wholly castaneous or testaceous forms

occur of several of the metallic zneous species, as S. glabrata, S. wrata, &c. Other

species, S. inconstans, S. irregularis, S. nigripennis, &c., are also very inconstant in

colour, these having the elytra striped or spotted in some examples and unicolorous

in others. All the species here included in Statira agree in having (so far as can

be ascertained from an external examination in some cases, as regards the mouth-

parts) the apical joint of the labial palpi narrow and ovate; the mandibles simply

unidentate or feebly bifid; the outer lobe of the maxilla comparatively narrow; the

anterior coxe moderately exserted and not contiguous, the prosternum narrowly raised

between them, usually to the level of the cox (thus differing from Lagria, Emydodes,

Arthromacra, and, probably, Eutrapela also); the femora gradually widening from the

base; the elytra without opaque lateral patch ; and the head more or less narrowed or

constricted behind into a neck.. The eyes vary considerably in size in the different

species, but the head is usually narrowly extended on each side behind them. The

apical joint of the antenne in some species is very long, often exceedingly elongate in

the male; but in others (S. glabrata, S. irregularis, &c.) it is only about as long as

joints 8-10 or 9 and 10 united, and not longer in the male than in the female. The

presence or absence of a complete lateral carina to the thorax, the clothing or armature

of the femora and tibiz, and the sulcation of the latter (recently noticed by Dr. Horn),

are characters of great assistance in discriminating the numerous species: none of these

points of difference are noticed by Maklin. The armature of the anterior femora and

tibiee in the species here placed at the beginning of the genus, it may be noted, is not

a male character, but is shared equally by the female. The spurs of the tibie, though

short, are quite distinct in many of the species, while they are indistinct in others.

A few species of small size, §. irregularis &c., have the thorax transversely convex

and short, the apical joint of the antenne comparatively short in both sexes, and the

prosternum exceedingly narrow and raised nearly to the level of the anterior coxe ;

they cannot, however, be satisfactorily separated from Statira*. The number and

position of the setiferous impressions on the elytral interstices afford good specific

characters. The sixth ventral segment is sometimes extruded and visible ; but, like the

elongate apical joint to the antenne in the male, it is apparently of no value as a generic

character in this family t+. Most of the species obtained by myself were found upon

herbage or under loose bark, or beaten from the decaying branches of fallen trees. The

earlier stages are probably passed in rotten wood or in decaying vegetable matter.

The following table will assist in the recognition of the Central-American species ¢ ;

but it must be remarked that certain species which are otherwise closely allied are by

this arrangement widely separated, e.g. S. nigrosparsa and S. guatemalensis :—

* South-American species differing thus from Statira are noted by Lacordaire (Gen. Col. v. p. 572, nota).

+ Leconte and Horn (Class. Col. N. Am. 1883, p. 393) state that the ‘Statirini’ are distinguishable by these -

characters from the genuine ‘ Lagriini’; but this is a mistake, The former, however, may be known from

the latter by the prosternum being raised between the anterior coxe ; Arthromacra agrees with the ‘ Lagriini ’

in having tbe prosternum depressed or not raised between the anterior coxe.

+ S. tristis, Mikl., is unknown to me, and owing to the imperfect description it cannot be included in the

table; it is accordingly placed at the end of the genus.

Statira glabrata, Makl. Act. Soc. Fenn. vii. p. 587°.

Hab. Mexico 4, Cordova, Yolos (Sadlé), Jalapa, Chilpancingo (Hoge, H. H. Smith) ;

British Honpuras, R. Hondo (Blancaneaux); GuatnMaLa, Capetillo, San Gerdénimo

(Champion).

Var. «. Elytra bluish-green, the interstices feebly convex.

Hab. Mexico, Chilpancingo (Hége), Cuernavaca (Sallé); GuatemaLa, San Geronimo

(Champion).

Var. B. Entirely castaneous, the antenne ferruginous, the legs testaceous.

Hab. Mexico, Presidio (Forrer). One example (9 ).

This is one of the most remarkable species of Statira and distinguished from all others

of the genus, except the following, by the shape of the anterior femora and tibie: the

former are coarsely denticulate and furnished with long scattered hairs on their inner

edge, and very stout, and the latter are much curved and armed on the inner side a little

beyond the middle with a sharp triangular tooth; these characters are precisely similar

in both sexes. In the typical form the elytral interstices are perfectly flat, but in the

variety « (examples of which were collected in two localities with others of the type-

form) they are feebly convex. The third and fifth elytral interstices have each about

four or five moderately coarse scattered setiferous punctures, one or two of which are

sometimes obsolete or irregularly placed; and the ninth, in rare examples, has one or

two similar punctures towards the apex. ‘The number of teeth on the anterior femora

varies from ten to fifteen. The antenne are similarly formed in both sexes, and are

ferruginous, with the three basal joints piceous; and the apical joint is about as long

as, or a little longer than, joints 8-10 together. The examples from British Honduras

have the elytra brownish-piceous with a translucent eneous tinge, and the variety ( is

entirely castaneous. 8S. glabrata was captured in great abundance at Jalapa and Cape-

tillo; more than 100 examples have been received.

2. Statira denticulata.

Elongate, zeneous or greenish-eneous, the elytra sometimes cupreous in ‘tint at the sides and apex, shining.

Head with a few exceedingly minute scattered punctures; eyes moderately large; antennee moderately

long, and similar in both sexes, piceous or piceo-ferruginous, the apical joint longer than joints 8-10

united ; prothorax longer than broad, the sides much rounded anteriorly, strongly constricted behind, and

obsoletely margined at the extreme base, the hind angles sharp and prominent, the base strongly margined

and the margin raised, the surface sparsely and minutely punctured; elytra with shallow intrahumeral

depression, moderately long, widest a little behind the middle, parallel anteriorly, shallowly and regularly

punctate-striate, the punctures fine and closely placed, the interstices flat, the third and fifth each with

seven or eight, the seventh with three or four (one near the base, the others near the apex), and the ninth

with five (widely separated), coarse setiferous punctures, the apices obtuse; beneath blackish-piceous,

almost smooth, and very shining; legs piceous, the tarsi lighter; anterior femora coarsely denticulate

(the teeth six or eight in number) and furnished with long scattered hairs on their inner edge, and very

stout, and the anterior tibia curved and armed on the inner side beyond the middle with a short triangular

tooth, in both sexes,

Length 10-104 millim.; breadth (at shoulders) 27 millim. (¢ 9.)

Hab. Panama, Bugaba, Caldera, David (Champion).

Numerous examples. This species is very closely allied to S. glabrata, but easily

distinguished by the seventh elytral interstice also having setiferous punctures, and the

ninth (instead of having two or three at the apex) five widely separated punctures; the

teeth on the anterior femora are fewer in number; and the antenne are darker and

have a comparatively longer apical joint. Towards the apex of the elytra the setiferous

punctures are, as usual, coarser and closer, but on the ninth interstice they are coarse

throughout and almost equidistant.

3. Statira unidentata. (Tab. I. fig. 2, .)

Closely resembling S. glabrata and S. denticulata and differing as follows :—The anterior tibie unarmed within

and a little curved, and the anterior femora with a broad triangular tooth on the inner side a little beyond

the middle, in both sexes; the antenne similarly formed in both sexes, ferruginous, the basal joint

usually darker, the apical joint rather longer than joints 8-10 united; the elytra a little depressed on the

disc, the surface of a unicolorous greenish-eeneous tint, the third and fifth interstices each with about seven,

the seventh with three or four (one near the base, the rest near the apex), and the ninth with about four

(between the middle and the apex), moderately coarse setiferous punctures, the apices obtuse; the legs

ferruginous, the femora and tibie usually more or Jess piceous.

Length 10-11 millim.; breadth (at shoulders) 23-3 millim. (¢ 2.)

Hab. Mexico, Playa Vicente (Sailé), Tapachula in Chiapas (Hége); Britis

Honpuras, R. Hondo (Blancaneaux); GuateMaLa, San Gerdénimo (Champion).

Eight examples. Though very closely resembling S. glabrata and S. denticulata in

its general facies, this insect can be identified at once by the structure of the anterior

legs. As in both these species, the sides of the thorax are obsoletely margined at the

extreme base.

1 4, Statira interrupta. (Tab. I. fig. 3, ¢.)

Elongate, eneous or greenish-zneous, very shining; the elytra towards the base more or less golden in tint

and Jaterally (especially towards the apex) with bright cupreous reflections, entirely greenish-eneous, or

(very rarely) greenish-violaceous. Head almost smooth; eyes large; antenne moderately long and joints

3-10 rather elongate in both sexes, fusco-ferruginous, the three basal joints piceous—the apical joint

in the male about or nearly as long as joints 8-10 united, in the female a little shorter (about three times

as longas 10); prothorax rather longer than broad, the sides much rounded anteriorly, strongly constricted

behind, and very finely margined at the extretpe base, the hind angles sharp and prominent, the base

strongly margined and the margin raised, the surface sparsely and minutely punctured ; scutellum piceous ;

the inner side some distance beyond the middle, the space between the tooth and the apex densely clothed

with fulvous hair, in both sexes.

Hab. Nicaraeva, Chontales (Belt); Panama, Bugaba, Volcan de Chiriqui (Champion).

Var. B. The elytra reddish-castaneous, the base (sometimes very narrowly, sometimes to beyond the middle)

geneous or greenish-eneous ; the legs and antennex varying in colour, the former from piceous to reddish-

testaceous, the latter from fusco-ferruginous to reddish-testaceous.

Hab. Panama, Bugaba, Volcan de Chiriqui, San Feliz, Tolé (Champion).

Var. y. The prothorax more closely and more distinctly punctured; the elytra brownish-piceous, with a

translucent sneous tinge, the setiferous punctures on the third interstice fewer in number.

Hab. GuaTEMALA, Panima in Vera Paz (Champion). A single male example.

Three of the forms were collected by myself in plenty in Chiriqui; from Nicaragua

eight examples have been received, three of the typical form, and five of the variety a.

S. interrupta is probably an ally of the Colombian S. hilaris, Makl. (to judge from the

description), it having towards the apex the spaces between the setiferous punctures on

the third, fifth, seventh, and ninth interstices of the elytra longitudinally raised; the

present insect is, however, larger, and has the thorax and elytral strie differently

punctured. Other allied species inhabit Tropical South America.

5. Statira chiriquina. (Tab. I. fig. 4, ¢.)

Elongate, «neous or greenish-wneous, very shining, the elytra sometimes entirely and sometimes laterally

and towards the apex of a more cupreous tint. Head almost smooth; eyes large; antennz moderately

long and joints 3-10 rather elongate in both sexes, piceous or piceo-ferruginous, the three basal joints

darker—the apical joint in the male rather longer than, in the female about equal to, joints 8-10

united ; prothorax about as long as broad, the sides much rounded anteriorly, strongly constricted behind,

and obsoletely margined at the extreme base, the hind angles sharp and prominent, the base broadly

margined and the margin raised, the surface sparsely and very minutely punctured; elytra with shallow

intrahumeral depression, moderately long, widest a little beyond the middle, parallel towards the base,

very finely and shallowly punctate-striate, the punctures closely placed though a little more scattered

towards the apex, the interstices perfectly flat throughout, the third and fifth each with five or six, the

seventh with two or three (one near the base and one or two near the apex), and the ninth with about

three (towards the apex), deep and coarse setiferous punctures, the first very deeply impressed within the

sutural angles, the latter obtuse; beneath blackish-piceous, very shining, almost smooth ; legs sneo-

piceous, the tarsi rather lighter ; anterior femora on their inner edge clothed with long scattered hairs,

and the anterior tibice armed with a short triangular tooth on the inner side beyond the middle, the

space between the tooth and the apex densely clothed with fulvous hair, in both sexes.

Length 11-123 millim.; breadth (at shoulders) 33-33 millim., (¢ 2.)

10 HETEROMERA.

Hab. Panama, Volcan de Chiriqui 3000 feet (Champion).

Many specimens of this insect were captured by myself on the forest-clad slope of

the Volcan de Chiriqui. S. chiriquina closely resembles S. glabrata in general facies ;

but it is considerably larger, and, as well as having very differently-formed anterior

femora and tibiz, has the setiferous punctures on the elytra much coarser and deeper,

. and also present on the seventh interstice ; the antenne are not so stout, and the apical

joint in the male is comparatively much longer.

6. Statira scitula.

Elongate, varying in colour from dark piceous-brown to reddish-castaneous, the elytra varying from seneous to

reddish-castaneous with a translucent eneous tinge, sometimes slightly cupreous at the sides towards

the apex, shining. Head very distinctly and rather coarsely punctured between the eyes and posteriorly ;

eyes moderately large, smaller in the female; antenne more or less ferruginous, the three basal joints

darker—the apical joint in the male nearly as long as joints 6-10,in the female rather longer than

8-10, united; prothorax longer than broad, strongly constricted at the sides behind, the latter immar-

ginate or obsoletely margined towards the base, the hind angles sharp and prominent, the basal margin

raised and deeply grooved within, the surface finely and sparsely (sometimes more closely) punctured ;

elytra with shallow or rather deep intrahumeral depression, moderately long, widest about the middle,

parallel towards the base, finely and lightly punctate-striate, the punctures closely placed, the interstices

quite flat, the third with about five (widely scattered between the base and apex), and the ninth with one

or two (near the apex), shallow setiferous punctures, the apices obtuse; legs varying in colour from

piceous to reddish-testaceous, moderately stout, the tibiz clothed with long hairs within ; anterior femora

furnished with long scattered hairs on their inner edge in both sexes.

Length 73-8 millim.; breadth (at shoulders) 2-24 millim. (¢ 2.)

Hab. Mexico, Jalapa (Hoge); Guaremata, San Gerénimo, Aceytuno (Champion).

Four male and three female examples. |

Var.? The elytra relatively longer, the rest as in the type. Length 84-9 millim. ( 9.)

Hab. Mexico, Jalapa (M. Trujillo); Guatemaua, Capetillo (Champion). Three

examples.

Like S. tropicalis, this is a perplexing and variable species; and it is only distin-

guishable from that insect by the more finely punctured elytral strie and flatter inter-

stices. S. scitula is perhaps a variety of S. tropicalis, but the difference in the elytral

sculpture (which seems to be constant) prevents me from treating it as such; in one of

the male examples the eyes are smaller and the apical joint of the antenne is rather

shorter than in the others.

The variety (in the absence of the male sex) is doubtfully referred to the same species.

7. Statira tropicalis.

Elongate, piceo- or reddish-castaneous, the elytra with the sides entirely or from the base to about the middle

and the base (usually) greenish-eeneous or golden-green, sometimes entirely greenish-aneous or eneous,

shining. Head rather coarsely punctured at the sides between the eyes and posteriorly ; eyes moderately

large, distinctly smaller in the female; antenne rather stout, moderately long, varying in colour from

ferruginous to piceous—the apical joint in the male as long as joints 6-10 united (7-10 decreasing in

length outwardly, 10 as broad as long), in the female much shorter, and not equalling 7-10 united (these

about equal in length); prothorax long, subcylindrical, rather strongly constricted at the sides behind,

the latter immarginate, the hind angles moderately prominent, the basal margin raised and rather deeply

grooved within, the surface sparsely (sometimes a little more closely) and quite finely punctured ; elytra

with long and deep intrahumeral depression, comparatively rather short, widest about the middle, parallel

towards the base, rather coarsely punctate-striate, the punctures not very closely placed, the interstices

flat (often a little convex on the apical half or two-thirds of the disc), the third with five (widely sepa-

rated, deep, and transverse), and the ninth with two or three (towards the apex), setiferous punctures, the

apices obtuse; legs moderately stout, varying in colour from ferruginous to piceous ; anterior femora with

a few long hairs on their inner edge in both sexes.

Length 73-73 millim.; breadth (at shoulders) 2-27 millim. (¢ 9.)

Hab. Mexico, Jalapa (Hége) ; British Honpuras, Belize, R. Hondo (Blancaneaua) ;

GuateMALA, Las Mercedes (Champion); Nicaragua, Chontales (Belt).

One male and six female examples. S. tropicalis is very variable in colour, and

closely resembles S. variabilis. ‘The example trom Las Mercedes has the elytra of a

unicolorous greenish-eneous tint, while two of those from British Honduras have only

the sides of the elytra of that colour; the two specimens from Nicaragua are totally

different in colour, but agree well enough in other respects.

8. Statira variabilis. (Tab. I. figg. 5, ¢; 6, ¢ var.) |

Elongate, subparallel, blackish-zeneous, the elytra of an neous, greenish-seneous, or cupreo-sneous tint and

with the lateral margins usually suffused with cupreous towards the apex, very shining. Head coarsely

and irregularly punctured at the sides between the eyes and posteriorly, the eyes moderately large, the

palpi black ; antenne rather stout (especially in the female), piceous, or piceo-ferruginous with the basal

joints darker—the apical joint in the male as long as joints 5-10 united (these latter gradually decreasing

in length outwardly, 9 as long as broad, 10 subtransverse), in the female very much shorter, scarcely

equalling joints 8-10 united (5-10 more elongate and subequal); prothorax longer than broad, sub-

cylindrical, the sides immarginate and rather strongly constricted behind, the hind angles sharp, the base

shallowly grooved within, the surface sparsely and very finely punctured; scutellum brownish-piceous ;

elytra with long and deep intrahumeral depression, moderately long, subparallel, finely and shallowly

punctate-striate, the punctures rather closely placed, the interstices flat throughout, the third with four

or five widely separated deep setiferous punctures and the ninth with one or two shallower ones at the

apex, the apices obtuse; beneath blackish-piceous, very shining; legs rather slender, piceous ; anterior

femora with long scattered hairs on their inner edge in both sexes.

chiefly distinguished from S. scitula and S. tropicalis by the still more elongate apical

joint of the antenne in the male. All three species have the head somewhat coarsely

punctured.

The variety, at first sight, appears to be quite distinct, but, in reality, only differs in

colour. JS. variabilis varies considerably in size.

9. Statira agreformis. (Tab. I. fig. 7, 3.) |

Very elongate, brownish-piceous, the elytra darker and of a blackish-bronze tint, moderately shining. Head

with a few minute scattered punctures, shallowly impressed in the middle between the eyes, the latter

very large ; antennex long, moderately stout, fusco-ferruginous, the apical joint in the male about as long

as joints 6-10 united, the latter gradually decreasing in length outwardly; prothorax much longer than

broad, the sides obsoletely margined at the extreme base and very distinctly so in front, a little rounded

about the middle, distinctly narrowing anteriorly, and strongly constricted behind, the hind angles sharp

and prominent, the base strongly margined and the margin raised, the disc transversely and rather

broadly depressed in the middle before the base and apex and somewhat thickly punctured, the sides

more sparsely so and with a deep oblique fovea behind and a much shallower one before the middle;

elytra with indistinct intrahumeral depression, long, widest behind the middle, parallel towards the base,

with regular rows of large and rather broad oblong or elongate smooth tubercles from the base to the

apex, the tubercles flattened on the disc, and a little more elevated towards the sides and apex—each

surrounded by a line of rather coarse punctures, and those at the apex followed by a long erect bristle,

the apices rather sharply mucronate; beneath very shining, smooth, dark brownish-piceous; legs rather

long and slender, reddish-testaceous.

Length 133 millim. ; breadth (at shoulders) 33 millim. (<¢.)

Hab. Paxama, Bugaba 1000 feet (Champion).

This insect is perhaps nearest allied to the Brazilian S. gemmifer, Makl., of described

species, but others from the Amazons approach it more closely. SS. agreformis very

much resembles various Agre inhabiting the same district. The elytra exhibit a

beautifully catenulate sculpture; the tubercles are broader than in any of the

Amazonian species | have yet seen.

10. Statira ingens. (Tab. I. fig. 8, ¢.)

Elongate, broad, blackish-zeneous or seneous, the elytra of a more brassy tint, very shining. Head smooth,

longitudinally grooved between the eyes, the latter moderately large; antenne stout, piceous-black—the

apical joint in the male (in the female broken off) equalling joints 7-10 united (these decreasing in length

outwardly, 10 a little longer than broad); prothorax about as long as broad, the sides completely immar-

ginate, very strongly rounded anteriorly, and very abruptly and deeply constricted behind, the hind angles

sharp and prominent, the disc (in one example) shallowly canaliculate before the middle, the basal margin

raised and rather deeply grooved within (especially at the sides), the surface impunctate; elytra with

very shallow intrahumeral depression, long and broad, parallel to beyond the middle, finely and deeply

punctate-striate, the punctures approximate, the strie here and there a little sinuous, the interstices

feebly convex, the first, seventh, and ninth with one and the third and fifth with two (towards the apex

merging into one) irregular rows of somewhat closely placed moderately coarse setiferous punctures, the

intervals between the punctures laterally and towards the apex strongly raised and forming oblong

tubercles, the apices submucronate ; beneath blackish-neous, shining, smooth, the ventral segments with

from 4—8 setiferous punctures on each side; legs stout, piceous.

Length 20-23 millim. ; breadth 6-7 millim. (¢ Q.)

Hab. Nicaracua, Chontales (Belt) ; Panama, Obispo (Salvin).

STATIRA. 13

Two examples. This species is no doubt allied to the Colombian S. steinheili, Mak. ;

but its very much larger size, different colour, and shorter and broader thorax abun-

dantly distinguish it. S. ingens is much larger and broader than any other known

species of the genus. The setiferous impressions on the third and fifth elytral inter-

stices form two irregular rows from the base to considerably beyond the middle.

Hab. Mexico 12, Jalapa (Hoge).

Var. Larger and more elongate ; the elytra relatively longer, piceous-brown, the base fulvo-testaceous and the

suture lighter, the setiferous impressions on the alternate interstices coarser and deeper. Length

93 millim.

Hab. Mexico, Jalapa (Hoge).

This species was described from two broken examples, one with the head black and

the other with the head reddish-testaceous. 8. melanocephala is a small shining

reddish-testaceous species, with the head, antenne, and knees black or piceous, and the

alternate elytral interstices with numerous setiferous impressions scattered between the

base and apex. The head and thorax are almost smooth, having, at most, only very

minute widely scattered punctures; the latter is finely margined at the sides at the

base and almost smooth; and the apical joint of the antenne in the male is equal to

four, and in the female to rather less than three, of the preceding joints united.

Numerous examples were captured by Herr Hoge; none of these have the head red.

The variety, of which a single female example only has been received, merely differs in

the colour of the elytra and in being larger and more elongate.

12. Statira collaris. (Tab. I. fig. 10, 3.)

Elongate, narrow, shining, above and beneath black or piceous, the prothorax (and sometimes the head also)

red or reddish-testaceous. Head with some very minute punctures between the eyes, for the rest smooth,

the eyes small ; antenne black or piceous—the apical joint in the male not so long as joints 8-10 united

(the latter elongate), a little shorter in the female ; prothorax convex, about as long as broad, the sides

immarginate, rounded anteriorly, and strongly constricted behind, the hind angles acute, the basal margin

sharply raised and grooved within, the surface smooth ; elytra with shallow intrahumeral depression, long,

widest beyond the middle, very finely and very shallowly punctate-striate, the interstices flat, the first,

third, fifth, seventh, and ninth each with a row of closely placed fine setiferous punctures which extend

from the base to the apex, the punctures each preceded by an indistinct elevation, the apices slightly

pointed; legs black or piceous.

Length 7-84 millim.; breadth 13-2 millim. (¢ 2.)

Hab. Mexico, Jalapa (//6ge).

Five examples. In colour this species resembles 8. angustula, from which it differs

in its more shining surface, less parallel shape, and very differently sculptured elytra.

14 : HETEROMERA.

From S. melanocephala, apart from the difference in colour, it may be separated by the

very much more finely and shallowly punctured elytral strie and by the setiferous

impressions being each preceded by a sort of feeble elevation, and also by the much

shorter apical joint of the antenne in the male.

13. Statira ceruleipennis. (Tab. I. fig. 11, 3.)

Moderately elongate, rather broad, subopaque, reddish-testaceous ; the elytra dull blue, the suture indetermi-

nately and the epipleure reddish-brown. Head finely and thickly punctured, the eyes moderately large ;

antenne ferruginous, stout, comparatively short, the apical joint ( ¢ ) about as long as joints 6-10 united ;

prothorax large and broad, transverse, a little flattened on the disc, the sides finely margined at the

extreme base only, moderately rounded anteriorly, and strongly constricted behind, the hind angles acute,

the basal margin moderately raised, the surface densely and very minutely punctured; elytra with very

shallow intrahumeral depression, moderately long, very deeply striate throughout, the stri# with closely

packed fine transverse impressions, the interstices rather convex, strongly so towards the apex, the first

with three (one at the base, the others at the apex), the third with about eleven and the fifth with seven

(scattered between the base and apex), the seventh with two or three (one at the shoulder, the others at

the apex), and the ninth with five or six (near the apex), fine setiferous punctures, the apices obtuse ;

beneath obscure castaneous, very shining; legs rather stout, reddish-testaceous.

Length 104 millim.; breadth 3 millim. (¢.)

Hab. Mexico, Taretan (Hége).

One male example. ‘This comparative broad species is not very closely allied to any

other noticed here; it approaches S. multiformis. The elytra are dull blue, and the

rest of the insect in great part reddish-testaceous. ‘The tibia are not grooved on their

outer edge. The almost immarginate sides of the thorax and other particulars separate

it from S. mexicana and its allies. S. cwruleipennis is broader and more robust than

any other of the Central-American species with bluish elytra.

14. Statira limbata. (Tab. I. fig. 12, 3.)

Elongate, subopaque, reddish-testaceous ; the elytra usually more or less marked with piceous at the sides,

sometimes wholly piceous with the exception of the suture, sometimes entirely reddish-testaceous, and

slightly shining. Head smooth or with very minute scattered punctures, sometimes foveate in the

middle between the eyes, the latter small; antenne varying from piceous to ferruginous, the intermediate

joints distinctly widened towards their apex—the apical joint in the male about or scarcely equalling

joints 8-10 united (the latter elongate), a little shorter in the female ; prothorax about as long as broad,

the sides completely immarginate, rounded anteriorly, and strongly constricted behind, the hind angles

acute, the basal margin moderately raised and at the sides deeply grooved within, the disc sometimes

shallowly impressed in the middle behind, the surface smooth and opaque; elytra with shallow intra-

humeral depression, moderately long, widest beyond the middle, finely and shallowly punctate-striate (the

punctures sometimes transverse), the interstices flat or very feebly convex, the first with one (at the apex,

sometimes obsolete), the third and fifth each with from four to six (widely scattered between the base and

apex, the anterior ones sometimes obsolete), the seventh with one (at the shoulder, and, rarely, two or

three near the apex), and the ninth with three or four (towards the apex), fine setiferous punctures, the

apices obtuse; beneath (in all varieties) more or less testaceous ; legs usually reddish-testaceous with

the apical half or third of the femora (and sometimes the tibie and tarsi) piceous, sometimes wholly

testaceous.

Jalapa (Hége), Teapa in Tabasco (Hoge, H. H. Smith), Temax in North Yucatan

(Gaumer); British Honpuras, R. Hondo (Blancaneauz).

A common species on the Atlantic slope of Central and Southern Mexico and also

inhabiting British Honduras, but apparently not extending into Guatemala. S. limbata

is closely allied to S. vilis, and is found in many of the same localities. It differs

constantly from that species in its more elongate shape and less shining surface; the

apical joint of the antenne very much shorter in the male, and to a less degree in the

female; and the head and thorax almost smooth, the latter opaque. In none of the

varieties of S. vilis are the elytra coloured as in the normal form of S. limbata, 7. e.

having the sides rather narrowly piceous. ‘The under surface in S. limbata is always

more or less testaceous, while in the dark forms of S. vilis it is piceous. The duller

upper surface, differently-formed antenne, smooth thorax, and very few setiferous punc-

tures on the elytra easily separate S. limbata from S. melanocephala.

15. Statira angustula.

Elongate, narrow, subparallel, depressed, opaque, above and beneath black, the head and prothorax red or

reddish-testaceous, the former sometimes a little darker. Head almost smooth, or with scattered very

minute punctures ; the eyes small, black ; antenne rather slender, piceous—the apical joint in the male

rather longer, in the female less, than joints 8-10 united; prothorax about as long as broad (sometimes

a little shorter), the sides obsoletely margined at the extreme base only, rounded anteriorly, and strongly

constricted behind, the hind angles acute, the basal margin moderately raised and at the sides grooved

within, the disc shallowly depressed in the middle behind, the surface smooth; elytra with long and

rather shallow intrahumeral depression, long, subparallel, finely and rather deeply punctate-striate, the

interstices flat but becoming a little convex towards the apex, the first with one or two (at the apex), the

third with four or five and the fifth with two or three (between the middle and apex), the seventh with

one (at the shoulder), and the ninth with three or four (near the apex), setiferous punctures, the apices

obtuse ; legs slender, piceous.

Length 7-72 millim.; breadth 14-1? millim. (¢ 9.)

Hab. GuatTEMALA, near the city 5000 feet (Salvin).

Five examples. Narrower, more parallel, and more depressed than S. dimbata, from

dark-coloured examples of which it may also be known by the elytra, legs, and under

surface (except that of the head and prothorax) being entirely black or piceous. ‘The

antenne are also more slender and have a rather longer apical joint, and the elytra are

opaque.

16. Statira suavis.

Elongate, narrow, piceous-brown, subopaque. Head smooth, broadly and shallowly foveate between the eyes,

the latter small; antenne comparatively stout, rather long, ferruginous—the apical joint in the male not

equalling joints 8-10 united; prothorax convex, about as long as or rather longer than broad, the sides

immarginate (except at the extreme base and there only obsoletely so), moderately rounded anteriorly,

and strongly constricted behind, the hind angles acute, the basal margin moderately raised, the surface

smooth; elytra with rather deep intrahumeral depression, very finely and shallowly punctate-striate, the

interstices flat but becoming convex towards the apex, the first with from two to four (near the apex),

legs piceo-testaceous or testaceous.

Length 64 millim.; breadth 13 millim. (¢-)

Hab. Mexico, Ventanas in Durango (Hoge).

Two examples. A small, narrow, unicolorous species, not very closely allied to any

other known to me. It resembles S. angustula in size and shape; but the thorax is

relatively longer, and the elytra have more finely punctured striz, and more numerous

setiferous impressions on the third, fifth, and seventh interstices.

17. Statira metallica. (Tab. I. fig. 13, ¢ .)

Elongate, reddish-castaneous or brownish-piceous, shining, the elytra eneous or greenish-geneous and some-

times cupreous in tint at the sides towards the apex. Head rather sparsely and irregularly but quite

distinctly (subrugulosely at the sides in one or two examples) punctured between the eyes and posteriorly,

the latter large; antenne moderately long and rather slender, ferruginous—the apical joint in the male

very elongate, nearly equalling joints 6-10 united, in the female shorter and about equalling 7-10 united ;

prothorax rather longer than broad, the sides much rounded anteriorly, very strongly constricted behind,

and obsoletely margined at the extreme base, the hind angles sharp and very prominent, the base broadly

margined and the margin raised, the surface closely but exceedingly minutely punctured ; elytra with

shallow intrahumeral depression, long, widest behind the middle, subparallel towards the base, finely and

shallowly punctate-striate, the punctures very closely placed, the interstices flat or very feebly convex,

the third with five (all placed beyond the middle), the fifth with about six (scattered between the base

and apex), the seventh sometimes with one (close to the apex), and the ninth with about three (towards

the apex), moderately coarse setiferous punctures, and the first deeply impressed within the sutural angles,

the latter obtuse; beneath brownish-piceous, very shining ; legs piceous or ferruginous, rather slender.

Length 113-122 millim. ; breadth (at shoulders) 33 millim. (¢ 9.)

Hab. Nicaragua, Chontales (Belt); Costa Rica, Irazu (Rogers).

Three female examples from Nicaragua and a male from Costa Rica.

Var. The seventh elytral interstice with three setiferous punctures near the apex; the antenne fusco-

ferruginous.

Hab. Panama, Bugaba (Champion). A single male example.

This species is chiefly distinguished amongst its allies by the distinctly and irregularly

punctured head and the closely and very minutely punctured thorax. The simple

anterior tibize and femora separate it from S. glabrata &c. The presence of a setiferous

puncture on the seventh elytral interstice at the apex is a variable character, it being

altogether obsolete in one example; the variety only differs from the type in having

two additional punctures on the seventh interstice. The apical joint of the antenne in

the male is very elongate. The cedeagus of the male is of peculiar form :—the apical

portion of the central sheath is spoon-shaped, and on either side of this, and just

behind it, is a stout hook curved upwards; in S. glabrata the sheath is gradually

narrowed to the end and unarmed, and the apical portion is much more elongate.

18. Statira inconstans. (Tab. I. fig. 14, @ var.)

Elongate, brownish-piceous, the elytra greenish-aneous, shining. Head sparsely and minutely punctured or

almost smooth, the eyes quite small and widely separated in both sexes, the space behind them rather

broad ; antenne reddish, slender towards the base, thickening outwardly—the apical joint in the male

almost the length of joints 6-10, in the female about as long as 8-10, united; prothorax longer than

broad, the sides feebly margined towards the base, slightly arcuate anteriorly, and only moderately

constricted behind, the hind angles acute, the basal margin moderately raised, and at the sides shallowly

grooved within, the surface very shallowly, sparsely, and minutely punctured (the punctures sometimes

more distinct) and without any trace of fovew in either sex; elytra with long and rather shallow intra-

humeral depression, moderately long, widening gradually from the base to beyond the middle, rather

deeply striate throughout, the punctures of the striz fine and close, the interstices feebly convex but

becoming flatter towards the base, the third and fifth each with from six to eight (scattered between the

base and apex), the seventh sometimes with one (at the shoulder), and the ninth with about six (chiefly

towards the apex), moderately coarse setiferous punctures, the apices obtuse ; beneath brownish-piceous,

shining ; legs rather slender, piceo-testaceous, the tarsi testaceous.

Length 63-82 millim.; breadth (at shoulders) 13-23 millim. (¢ 9.)

Hab. Guatemata, Cubilguitz in Vera Paz (Champion) ; Nicaracua, Chontales

(Belt).

Var. The head and prothorax usually lighter in colour, the base and apex of the latter more or less reddish-

testaceous ; the elytra testaceous, with the sides for about two-thirds of their length, the base (narrowly),

and a transverse band about the middle (connected with the lateral stripe and widening a little at the

suture and laterally) more or less greenish-eeneous, and a triangular common sutural patch (sometimes

connected with the lateral stripe) midway between the transverse band and the apex piceo-sneous ; legs

testaceous, the apices of the posterior femora sometimes darker. (3 2.)

Hab. GuatEMa.a, Cubilguitz in Vera Paz (Champion).

The unicolorous form is taken as the type, of which we have one male from Nicaragua

and two females from Guatemala; of the variety we have six examples.

The typical form of S. inconstans closely resembles S. foveicollis; it differs as

follows :—The head and thorax are without eneous tinge; the latter has no trace of

lateral fossa in either sex, and is only moderately constricted behind; the eyes are

smaller; and the elytra are more deeply striate, and have from six to eight rather

coarse setiferous impressions on both the third and the fifth interstices.

From 8. vélis in all its varieties the more or less greenish-zneous elytra and invariably

reddish-testaceous antenne distinguish it at once.

Both forms were collected together at Cubilguitz.

19. Statira viridicollis. (Tab. I. fig. 15, 3.)

Very elongate, rather depressed, greenish-eneous, the elytra of a more brassy tint, shining. Head sparsely

and finely punctured, the eyes large ; antenne long and rather. stout, fusco-ferruginous, the basal joint

darker, the apical joint in the male as long as joints 6-10 united, these latter rather elongate, 10 very

little shorter than 9; prothorax about as long as broad, a little flattened on the disc, the sides narrowly

margined towards the base, moderately rounded anteriorly, strongly constricted behind, and with traces

of an irregular transverse depression about the middle, the hind angles acute and very prominent, the

basal margin moderately raised and shallowly (except in the middle) grooved within, the surface irregularly,

rather closely, and not very finely punctured, a narrow longitudinal space on the middle of the disc almost

impunctate ; elytra with very shallow intrahumeral depression, very long, a little flattened on the disc,

subparallel to about the middle, finely and deeply punctate-striate, the punctures closely placed, but more

scattered towards the apex, the interstices feebly convex, the third with four (near the apex), the fifth

and the ninth with three or four (near the apex), shallow setiferous punctures, the apices a little produced

but not mucronate; beneath brownish-piceous, shining; legs rather long and slender, the tarsi com-

paratively broad, piceo-zeneous, the tibie and tarsi fusco-ferruginous.

Length 11 millim.; breadth 3 millim. (¢.)

Hab, Panama, Volcan de Chiriqui 3000 feet (Champion).

One male example only. This species is of about the size and shape of (though

more parallel than) 8. ver@pacis, from which its shining head and thorax (the latter

thickly punctured instead of smooth), much larger eyes, stouter and very differently

formed antenne, and broader and shorter tarsi abundantly distinguish it; from S. wne-

pennis it may be known by its very much longer antenne and other characters mentioned

above.

20. Statira foveicollis. (Tab. I. fig. 16, ¢.)

Elongate, rather narrow, varying in colour from piceo-zeneous with a greenish or violaceous tinge (the elytra

sometimes more brilliant) to light brown with an eneous lustre, shining. Head almost smooth, the oral

organs piceous, the eyes large ; antenne rather slender, moderately long, testaceous or fusco-testaceous—

the apical joint in the male a little longer than joints 6-9, in the female 8-10, united ; prothorax rather

longer than broad, the sides obsoletely margined at the extreme base, rounded anteriorly, and strongly

constricted behind, the hind angles acute, the basal margin moderately raised and at the sides deeply

grooved within, the surface sparsely and minutely punctured—in the male with a deep oblique lateral

fossa (opaque and punctured within) about the middle, the corresponding space in the female being

shallowly or obsoletely impressed and furnished with coarse scattered punctures; elytra with long and

deep intrahumeral depression, moderately long, widest a little beyond the middle, subparallel towards the

base, a little flattened on the disc, finely, closely, and rather deeply punctate-striate throughout, the

interstices flat but becoming a little more convex towards the apex, the third with four (one at the

extreme base and three near the apex), the seventh with one (at the shoulder), and the ninth with two or

three (near the apex), fine setiferous punctures, the apices obtuse; beneath varying in colour from fusco-

testaceous to piceous-brown, shining ; legs rather slender, piceous or piceo-testaceous.

Hab. British Honpuras, R. Hondo (Blancaneauxr) ; Nicaragua (Sallé), Chontales

(Belt, Janson); Panama, Bugaba (Champion).

Numerous examples. A small narrow species, «neous above, with testaceous

antenne, very few setiferous punctures on the elytra, and very remarkable sexual

characters. These latter consist of a large oblique fossa on each side of the thorax

(precisely similar in the numerous examples examined) in the male, the corresponding

space in the female being obsoletely and obliquely impressed and furnished with

coarser punctures than the rest of the surface.

21. Statira crassicornis. (Tab. I. fig. 17, 2.)

Moderately elongate, subparallel, depressed, blackish-aneous, the elytra of a more brassy tint, moderately

shining. Head short and very broad, minutely and rather thickly punctured; eyes (2) very large,

narrowly separated ; antenne (@) ferruginous, the five basal joints piceous, exceedingly stout, com-

paratively short, the apical joint longer than joints 9 and 10 united (but not equalling 8-10), 8-10 longer

than broad and subequal; prothorax broad, very strongly transverse, the sides completely immarginate

behind, the hind angles acute, the basal margin much raised and laterally very deeply grooved within, the

disc flattened, the surface rather densely, irregularly, and very minutely punctured (the disc with

numerous very fine irregular scratches), the sides smoother ; elytra with long and rather deep intrahumeral

depression, comparatively short, subparallel to beyond the middle, flattened on the disc, very finely and

closely punctate-striate, the interstices flat, the third, fifth, and ninth each with about six (scattered

between the base and apex and almost equidistant), and the seventh with one (at the shoulder), fine

setiferous punctures, the apices obtuse ; beneath piceous-brown, shining; legs short and stout, piceo-

ferruginous, the femora darker towards the apex, the tarsi ferruginous.

Length 8$ millim.; breadth 24 millim. ( 2.)

Hab. Mexico, Teapa in Tabasco (H. H. Smith, April 1888).

A single female example. S. crassicornis is not closely allied to any other known

Central-American member of the genus, though it closely approaches one or two species

from the Amazonian region. The very broad head, large eyes, strongly transverse

thorax, stout limbs (the antenne exceedingly stout), depressed and rather short form,

and other characters mentioned above give S. crassicornis a facies quite distinct from

any other species here enumerated.

22, Statira isthmiaca. (Tab. I. fig. 18.)

Moderately elongate, rather broad, depressed, blackish-seneous, the elytra of a unicolorous bright greenish-

geneous tint, shining. Head shallowly longitudinally impressed between the eyes in the middle, almost

smooth, the eyes small; antenne rather short, slender, ferruginous but darker towards the base—the

apical joint in the male fully as long as, in the female a little shorter than, joints 8-10 united ; prothorax

about as long as broad, the sides completely immarginate, strongly rounded anteriorly, and abruptly

constricted behind, the hind angles prominent and rather acute, the basal margin much raised but

scarcely grooved within, the surface with exceedingly minute widely scattered punctures; elytra with

shallow intrahumeral depression, rather broad, comparatively short, widest beyond the middle, shallowly |

transversely impressed on the disc below the base, finely, closely, and rather deeply punctate-striate

throughout, the interstices fat or feebly convex, the third with three (between the middle and apex, the

anterior one sometimes obsolete), the fifth with two (one near the apex and one near the middle, the

latter sometimes obsolete), the seventh with one (at the shoulder), and the ninth with three or four (near

the apex), fine setiferous punctures, the apices a little produced but obtuse; beneath piceous-brown,

shining ; legs slender, piceous, the tarsi lighter.

Length 9-93 millim. ; breadth (at the shoulders) 23-22 millim. (¢ 2.)

Hab. Panama, Volcan de Chiriqui 3000 feet (Champion).

One male and two female examples. The unicolorous and transversely impressed

elytra, fine setiferous punctures, almost smooth head and thorax (the latter immar-

ginate), and shorter and more slender antenne distinguish this species in a moment

from S. ignita, to which it is in other respects nearly allied.

moderately prominent, the basal margin raised and at the sides rather deeply grooved within, the surface

closely and very minutely punctured; elytra with shallow or rather deep intrahumeral depression,

moderately long, very finely punctate-striate, the punctures quite shallow, transverse, and approximate,

the interstices flat or feebly convex but becoming more convex towards the apex, the third with three or

four and the fifth with one or two (towards the apex), the seventh with one (at the shoulder), and the

ninth with two or three (at the apex), coarse setiferous punctures, the punctures (the one on the seventh

excepted) usually fuscous in colour and extending completely across the interstice, the apices obtuse ;

legs (and under surface) varying in colour from piceous to reddish-testaceous.

Hab. Guatemaua, Chacoj (Champion).

The type-form and the var. 8 were captured in numbers; of the other varieties we

have only two or three examples of each. The typical form of S. multiformis resembles

that of S. nigrosparsa, as described by Maklin; it differs from it in having the head

and thorax very much smoother, the latter being closely and minutely punctured (not

scabrous), almost immarginate at the sides (in S. nigrosparsa the sides are very distinctly

margined throughout), and with less prominent anteriorangles. There are no setiferous

impressions at the apex of the first elytral interstice, and only two or three towards the

apex of the third and fifth, in & multiformis. This species appears to be still more

variable in colour than S. nigrosparsa; the typical form much resembles a Calleida

inhabiting the same district. The apical joint of the antenne of the male varies in

length, and in some Chiriqui examples nearly (if not quite) equals the six preceding

joints united. The tibiez are not grooved on their outer edge.

24. Statira tolensis.

Elongate, subopaque, reddish-testaceous, the elytra of a more testaceous tint. Head closely and finely

punctured; the eyes large, black ; antennee ferruginous, moderately stout, the apical joint (3) about as

long as joints 7-10 united; prothorax convex, as long as broad, the sides obsoletely margined at the base

and apex, a little rounded at the middle, somewhat oblique in front, and strongly constricted behind, the

hind angles acute, the basal margin thick, moderately raised, and at the sides grooved within, the surface

finely and densely punctured, the disc more sparsely so in the middle behind and there somewhat

flattened ; elytra with very shallow intrahumeral depression, long, widest beyond the middle, deeply

striate throughout, the strie with closely packed fine transverse impressions, the interstices convex, more

strongly so towards the apex, the third with about six and the fifth with three (widely scattered between

the base and apex), the seventh with one (at the shoulder), and the ninth with about six (towards the

apex), fine setiferous punctures, the apices obtuse ; legs and under surface testaceous, the former rather

stout.

Length 117 millim.; breadth 2-22 millim. (¢.)

Hab. Panama, Tolé (Champion).

One example only. More elongate, larger, and more robust than S. penicillata, and

also differing thus :—The eyes are larger; the thorax is not completely margined at

the sides, and the surface is less densely and less confluently punctured (finely scabrous

in S. penicillata); the elytra have no setiferous impressions on the first interstice and

very few on the third and fifth; the legs are stouter ; and the posterior tibiz have not

a brush of short hairs in the male. WS. folensis is more elongate than S. ceruleipennis,

to which it is perhaps more nearly allied, and has larger eyes, more slender antennae, a

narrower thorax, and much longer elytra, the latter with fewer setiferous impressions

on the third and fifth interstices.

Var. Entirely piceous, the prothorax almost smooth.

Hab. Panama, Bugaba (Champion).

This is a common and widely distributed species in Central America. In the form

described by Maklin the head and thorax are reddish-testaceous, the elytra black or

piceous, and the legs and under surface piceous ; the insect, however, is often entirely

reddish-testaceous, about one third of our very numerous examples being thus coloured.

S. vilis is a small, moderately elongate, shining species, with the eyes small, the head

and thorax minutely and sparsely (sometimes more thickly) punctured, the latter

obsoletely margined at the extreme base, and the elytra rather deeply punctate-striate,

the third, fifth, and ninth (and sometimes the seventh) interstices each having from two

to four widely scattered setiferous impressions. ‘The apical joint of the antenne in the

male equals about five, and in the female rather more than three, of the preceding

joints united. Of the variety a single example only was. captured.

26. Statira sobrina,

Elongate, narrow, rather convex, moderately shining, fusco-testaceous, the head and the basal and apical

margins of the prothorax reddish-testaceous. Head broad, with exceedingly minute scattered punctures

(only visible under a strong lens), the eyes moderately large ; antenne( d ) reddish-testaceous, long, mode-

rately slender, the apical joint about as long as joints 5-7 united; prothorax subcylindrical, about as broad

as long, the sides obsoletely margined at the base and apex, moderately rounded anteriorly, and strongly

constricted behind, the hind angles acute and very prominent, the basal margin raised, the surface

sparsely and very minutely punctured ; elytra with rather deep intrahumeral depression, long, subparallel

in their basal half, very finely punctate-striate, the striae becoming deeper towards the apex, the interstices

flat, feebly convex towards the apex, the third with about eight (two or three towards the base and the

rest between the middle and apex), the fifth with one or two (near the apex), the seventh with one (at

the shoulder), and the ninth with two (at the apex), fine setiferous punctures, the apices obtuse ; beneath

reddish-castaneous ; legs rather long, moderately slender, reddish-testaceous, the femora smooth and

glabrous.

Length 7 millim.; breadth 2 millim. (¢.)

Hab. Mexico (coll. &. Bates).

A single male example only of this inconspicuous species, without more definite

locality, is contained in Mr. F. Bates’s collection. S. sobrina is chiefly characterized by

its narrow elongate shape, fusco-testaceous colour, very minutely punctured head and

thorax, and reddish-testaceous limbs; the third elytral interstice has about eight

setiferous impressions (scattered between the base and apex), and the fifth and ninth

have each one or two near the apex.. S. sobrina closely resembles S. trazuensis, but

differs in its much broader head, stouter antenne and legs, and distinctly (but very

finely) punctured thorax, and in the elytral interstices being rather convex towards the

apex, the third having more numerous setiferous impressions. From pallid forms of

S. limbata and 8S. vilis its more parallel shape and other characters sufficiently

distinguish it.

27. Statira ivazuensis.

Elongate, subopaque, obscure testaceous. Head narrow, almost smooth, the cyes small; antenna» testaceous,

stender, the apical joint ( ¢ ) a little longer than joints 9 and 10 united ; prothorax narrow, convex, the

sides finely margined at the base and apex, much rounded about the middle, slightly oblique in front,

and strongly constricted behind, the anterior angles a little prominent, the hind angles acute, the basal

margin moderately raised and at the sides grooved within, the surface almost smooth; elytra with shallow

intrahumeral depression, long, subparallel, finely punctate-striate, the striz becoming shallower towards

the apex, the interstices flat throughout, the third and ninth each with two or three fine setiferous

punctures near the apex, the apices obtuse ; legs testaceous, slender.

Length 8 millim.; breadth 2 millim. ( 9.)

Hab. Costa Rica, Volcan de Irazu 6000 feet (Logers).

A single female example only. 8S. drazuensis resembles the pallid unicolorous form

of S. limbata; it differs from it, however, in its proportionately narrower head and

parallel and longer elytra, the latter only having two or three setiferous impressions on

the third and ninth interstices,

narrow curved purplish-cupreous one, the latter shading off into golden behind. Head broad, closely and

coarsely punctured, the eyes (2) small and widely separated ; antennz ( ? ) piceo-ferruginous, long and

rather slender, the joints elongate, the apical joint the length of joints 9 and 10 united ; prothorax rather

(almost straight in front), and only moderately constricted behind, the basal margin much raised but not

grooved within, the hind angles acute, the disc with a shallow oblique groove on each side behind, the

surface closely, coarsely, and equally punctured; elytra with very shallow intrahumeral depression,

rather broad, comparatively short, widest beyond the middle, finely and rather deeply punctate-striate,

the punctures very closely placed, the interstices very feebly convex to about the middle and flat beyond,

the first with one (at the extreme apex), the third with two (towards the apex), the fifth with one (far

beyond the middle), the seventh with two (one near the apex and ove near the shoulder), and the ninth

with three (at the apex), coarse, but shallow, setiferous punctures, the apices a little produced, obtuse ;

beneath piceous-brown, shining; legs slender, piceo-ferruginous, the femora darker.

Length 9 millim.; breadth (at shoulders) 23 millim. (Q.)

Hab. Mexico, Jalapa (Hége).

A single specimen. This species and S. isthmiaca possess a different facies from the

other Central-American members of the genus, owing to their comparatively short,

broad, and depressed elytra. 8. ignita possesses a very peculiar system of coloration

of the elytra. Allied forms are found in South America.

29. Statira cupreotincta. (‘lab. I. fig. 22, 2.)

Elongate, light reddish-castaneous, the elytra greenish-zeneous, with the sides rather broadly from the base to

the apex (including the shoulders) suffused with cupreous, the base and a narrow space within the

eupreous part of a golden tint, shining. Head nearly smooth, except for three or four coarse shallow irre-

gular impressions between the eyes anteriorly and a deep and coarse puncture on either side behind; eyes

moderately large; antenne (Q ) ferruginous, rather short, the intermediate joints rather elongate, 8-10

subequal, 11 not so long as 8-10 united; prothorax rather broader than long, somewhat depressed on

the disc, the sides very finely margined throughout, strongly constricted behind, and but little rounded

anteriorly, the hind angles very sharp and prominent, the basal margin much raised though very

indistinctly grooved within, the disc with a rather deep transverse impression on either side before, and

an oblique one on either side behind, the middle, the surface with scattered irregular punctures, which

are more distinct at the base than elsewhere; elytra with long and shallow intrahumeral depression,

comparatively elongate, widest about the middle, parallel anteriorly, shallowly transversely impressed

on the disc below the base, finely but rather deeply punctate-striate, the punctures closely placed, the

interstices almost flat, the first with two (close to the apex), the third with about four (between the

middle and apex), the fifth with two or three (one at or before the middle and one or two towards

the apex), and the ninth with three (towards the apex), coarse and deep setiferous punctures, and the

seventh with a fine one at the shoulder, the apices obtuse; beneath reddish-testaceous ; legs slender,

reddish-testaceous.

Length 82 millim.; breadth (at shoulders) 23 millim. ( 9.)

Hab. Panama, Bugaba 1000 feet (Champion).

A single female example. This species somewhat resembles S. variabilis, but may

be readily distinguished by its transverse and laterally margined thorax, transversely

impressed elytra, glabrous anterior femora, and. other characters noticed above. The

fifth elytral interstice has four impressions on one elytron and only one on the other.

S. cupreotincta cannot be confounded with any other species here enumerated ; it

approaches the Colombian S. cupripennis, Makl., in some of its characters, though

differing in its short thorax and other particulars.

30. Statira verepacis. (Tab. I. fig. 23, 2.)

Very elongate, depressed, dull brownish-piceous, the elytra aneous or greenish-zeneous and slightly shining.

Head almost smooth, the eyes moderate in size; antenne very long and quite slender in both sexes,

fusco-ferruginous—the apical joint in the male as long as joints 8-10 (these latter elongate), in the

female rather longer than 9 and 10, united ; prothorax about as long as broad, a little flattened on the

disc, the sides very narrowly margined throughout, feebly rounded about the middle, moderately con-

stricted behind, and sometimes feebly emarginate anteriorly, the hind angles very acute, the basal margin

‘much raised but not grooved within, the surface impunctate; elytra with long and shallow intrahumeral

depression, very elongate and depressed, gradually widening from the base to far beyond the middle,

finely and lightly punctate-striate, the punctures approximate but more scattered towards the apex, the

interstices flat (the third, fifth, and seventh sometimes slightly convex towards the base), the first with

one or two (close to the apex), the third with about five (widely separated, the anterior two fine, the

others deeper and closer together), the fifth with one (towards the apex), the seventh with one (at the

shoulder), and the ninth with four or five (close together near the apex), setiferous punctures, the apices

slightly produced but not mucronate; beneath brownish-piceous, shining ; legs very long and slender,

piceous.

Length 104-12 millim.; breadth (at shoulders) 3 millim. (¢ 2.)

Hab. Guatemaa, Purula in Vera Paz (Champion).

Seven examples. The very long and slender limbs, depressed form, smooth and dull

head and thorax, and elongate shape distinguish this species from all others of the

genus here enumerated. ‘The following, S. curticollis, is allied to it; but differs in

having shorter legs and antenne, the intermediate Joints of the latter much less elongate

in both sexes, the thorax transverse, &c.

31. Statira curticollis, (Tab. I. fig. 24, ¢.)

Very elongate, depressed, brownish-black, opaque, the elytra piceous-brown and not so dull. Head with a

few minute shallow scattered punctures, the eyes small and widely separated ; antenne ferruginous,

rather short, moderately stout—the apical joint in the male about as long as joints 7-10, in the female

8-10, united; prothorax transverse, the sides narrowly margined from the base to the apex, very little

rounded and almost straight in front, and moderately constricted behind, the hind angles acute, the basal

margin only a little raised and at the sides grooved within, the surface smooth ; elytra with long and

deep intrahumeral depression, very elongate, if anything widest beyond the middle, subcoriaceous in texture,

the apical portion shining, finely and very shallowly punctate-striate, the punctures moderately close, the

interstices flat or very feebly convex, obsoletely punctured towards the apex, the first with about five

(near the apex), the third and fifth each with from seven to ten (scattered between the base and apex),

the seventh with one (at the shoulder), and the ninth with from seven to ten (between the base and

apex), shallow setiferous punctures, the apices a little produced but obtuse; legs long and slender, obscure

testaceous.

Length 82-94 millim.; breadth 21-23 millim. (3 2 .)

Hab. Mexico (coll. F. Bates), Capulalpam, Las Peras (Sa//é).

Six examples.

STATIRA. . Bb.

Var. a. Larger; the elytra with a slight greenish-sneous tinge, more elongate, the setiferous punctures on

the third, fifth, and ninth interstices much fewer in number (about four or five on each), the two outer

stris almost obliterated.

Length 103-11 millim.; breadth 23-3 millim. (¢ 2.)

Hab. Mexico, Salazar, Amecameca in Morelos (Hége).

Two examples.

Var. 3. The third and fifth interstices of the elytra with two or three very widely separated setiferous

impressions only, and the ninth with several, and the first with four or five (as in the type), near the apex.

Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith).

Var.? Broader; the setiferous impressions on the alternate interstices almost entirely obsolete (one or two

only visible on each at most), the apical interstices more distinctly punctured.

Length 11 millim.; breadth 3} millim. ( 2.)

Hab. GuateMaLa, Purula (Champion). One example.

This is a depressed elongate species, with smooth, opaque, and transverse thorax,

and very shallowly and finely punctate-striate elytra; the latter are subcoriaceous in

texture and at the apex shining and punctured, and also have some shallow setiferous

impressions on the first, third, fifth, and ninth interstices. SS. curticollis is different

in facies from the allied forms.

The var. « is represented by two mutilated specimens (the thorax in one of these

is more rounded at the sides in front), and the var. 8 by a similar number; the var. ?

from Guatemala, of which we have only a single abnormal female example, is possibly

distinct.

Labelled with the MS. name 8. drevicollis in Mr. F. Bates’s collection, a name

already preoccupied for another species.

32. Statira seneipennis. |

Elongate, depressed, rather broad, varying in colour from blackish-eneous to piceo-castaneous, the elytra

bright «neous or greenish-zneous with a golden tint, and the sides more or less suffused with cupreous,

very shining. Head with a few fine scattered punctures, the eyes moderately large; antennz moderately

long, rather slender, fusco-ferruginous, the basal joints darker—the apical joint in the male not quite so

long as joints 7-10 (these latter rather elongate), in the female rather less than 8-10, united; prothorax

about as long as broad, the sides very finely margined throughout, moderately rounded anteriorly, and

strongly constricted behind, the hind angles acute, the basal margin much raised but not grooved within, the

surface with a few fine indistinct scattered punctures; elytra with long and narrow intrahumeral

depression, elongate and depressed, considerably wider behind the middle than at the base, finely and very

lightly punctate-striate, the punctures approximate but more scattered towards the apex, the interstices

quite flat throughout, the first with two or three (near the apex), the third and fifth each with about four

(one near the base, the others towards the apex), the seventh with one (at the shoulder), and the ninth

(usually) with four or five (between the middle and apex), moderately coarse setiferous punctures, the

apices a little produced ; legs slender, moderately long, piceous or piceo-castaneous.

Length 94-114 millim.; breadth (at shoulders) 23-3 millim. (¢ 2.)

26 HETEROMERA.

Three examples and fragments of two others. Allied to S. verewpacis, but with the

upper surface much more shining ; the legs (the tarsi especially) and antenne much

shorter, the latter not nearly so slender; the elytra shorter and much more brilliant,

and the head and thorax shining and obsoletely punctured. In its brilliant metallic

colour, S. wneipennis resembles certain species of Calleida inhabiting the same

district.

33. Statira erata. (Tab. I. fig. 25, 3.)

Elongate, rather depressed, blackish-eneous, the elytra seneous, shining. Head with a few very fine scatiered

punctures, the eyes moderately large; antenne rather slender, moderately long, ferruginous, the basal

joints a little darker—the apical joint in the male equalling joints 7-10, in the female 8-10, united ;

prothorax about as long as broad (sometimes a little shorter), the sides narrowly but distinctly margined

from the base to the apex, a little rounded or slightly oblique in front, and strongly constricted behind,

the hind angles very acute and prominent, the basal margin much raised and shallowly grooved within

(deeply so at the sides), the surface very minutely, sparsely, and indistinctly punctured ; elytra with long

and deep intrahumeral depression, very shallowly transversely impressed below the base, widest beyond

the middle, moderately long, the disc slightly flattened, very closely, finely, and rather deeply punctate-

striate, the punctures transverse, the interstices flat or very feebly convex, the first with three or four

(near the apex), the third and fifth each with seven or eight (scattered between the base and apex), the

seventh with from four to six (one at the shoulder and the others between the middle and apex), and the

ninth with nine or ten (between the base and apex), rather deep setiferous punctures, the apices obtuse ;

beneath brownish-piceous, shining ; legs slender, moderately long, piceous, the tarsi lighter.

Length 9-10 millim. ; breadth (at shoulders) 24-22 millim. (¢ 2.)

Hab. Mexico, Jalapa (Hége), Atoyac in Vera Cruz (H. H. Smith).

Var. Entirely reddish-testaceous, the elytra with a translucent sneous tinge; the setiferous impressions on

the seventh interstice (except in one example) more numerous and extending upwards towards the

shoulder. (¢ Q.)

Hab. GouateMaLa, Purula (Champion).

Two examples of the type and three of the variety. ‘This insect is closely allied to

S. mexicana, but it cannot be satisfactorily treated as a variety of that species. Out of

a long series of examples of the latter, not one has the setiferous impressions on the

ninth elytral interstice continued up to the base (as in S. wrata), nor more than one or

two (at most and oftener than not obsolete) on the seventh near the apex. The setiferous

impressions on the apical third are not preceded, as in most examples of S. mexicana,

by a slight elevation, and the striz are not so shallowly punctured ; the anterior angles

of the thorax are also less prominent. The antenne are similarly formed in both

species. Not so brilliantly metallic as S. @neipennis (the elytra not cupreous at the

sides), and the setiferous impressions on the elytra more numerous and more

scattered.

34. Statira mexicana. (Tab. Il. fig. 1, ¢.)

Moderately elongate, shining, black or nigro-eneous, the elytra eneous or greenish-eneous. Head densely

and rugulosely, or closely and finely, or sparingly and minutely, punctured, the eyes not very large ;

antenne more or less ferruginous, moderately long, sometimes darker towards the base—the apical joint

STATIRA. 27

in the male fully or nearly equalling five, in the female about three, of the preceding joints united ; pro-

thorax about as broad as long (sometimes broader), the sides margined from the base to the apex, a little

rounded before the middle, oblique in front, and strongly constricted behind, the anterior angles prominent,

the hind angles acute, the basal margin moderately raised, and at the sides grooved within, the disc

shallowly impressed in the middle before the base, the surface closely and minutely (sometimes more

coarsely, sometimes still more finely) punctured; elytra with deep intrahumeral depression, moderately

long, sometimes feebly transversely impressed below the base, very finely punctate-striate, the punctures

quite shallow and approximate, the interstices feebly convex (flatter on the basal part of the disc), the

first with from four to seven (near the apex), the third with from seven to ten and the fifth with from five

to eight (scattered between the base and apex), the seventh with from one to three (one at the shoulder,

and one or two at the apex, the latter very often obsolete), and the ninth with from four to six (near the

apex), rather coarse setiferous punctures, the punctures on the apical third each usually preceded by a

more or less distinct elevation, the apices obtuse; legs more or less piceous, the tarsi ferruginous.

Length 74-10 millim.; breadth 23-3 millim. (¢ 9.)

Hab. Mexico, Jalapa (Hége), Cordova (Sallé).

Var. a. The prothorax and legs, and sometimes the head and elytra in great part, reddish-testaceous.

Hab. Mexico, Jalapa (Hoge).

Var. (3. Piceo- or reddish-testaceous, the elytra sometimes with a translucent neous tinge; the setiferous

impressions on the elytra not preceded by a slight elevation.

Hab. Mexico, Jalapa, Esperanza (Hoge), Cordova (Sallé).

Numerous examples of the type and of the var. a were collected by Herr Hoge at

Jalapa ; the var. 6 is an immature form.

This species may be distinguished from S. multiformis by the thorax being com-

pletely margined at the sides and having prominent anterior angles ; and also by the

more numerous setiferous impressions on the third and fifth elytral interstices, the first

also having several near the apex (there are none in S. multiformis), and the impressions

on the apical third usually preceded by a feeble elevation. From 8. nigrosparsa &c.

its non-scabrous thorax and more numerous setiferous impressions on the elytra

sufficiently separate it. The head and thorax vary a great deal in shape and sculpture

(though the latter always has the punctures separate one from another, and is never

scabrous) ; they are also narrower in some male examples than in others.

35. Statira eneotincta. .

Closely allied to S. mewicana, and differing as follows:—More elongate, the elytra especially; varying in

colour from brownish-piceous to reddish-testaceous, the elytra more or less téstaceous and often with a

translucent eneous tinge ; the antenne longer, and with more elongate penultimate joints in both sexes ;

the prothorax with less prominent anterior angles; the elytral interstices obsoletely punctured at the

apex, the first with about four (near the apex), the third and fifth each with about six (scattered between

the base and apex), the seventh with one (at the shoulder), and the ninth with four or five (near the

apex), setiferous punctures ; the rest as in S. meawicana.

Length 93-113 millim.; breadth 27-3 millim. (¢ 2.)

Hab. Mexico, Jalapa, Cordova (Hége); Guatemaa, Chiacam (Champion). .

Nine examples.. This is an immature-looking species allied to S. mexicana. Its

more elongate shape, longer antenne, and the elytral interstices obsoletely punctured

towards the apex (approaching S. punctipennis) are sufficient to distinguish it. In one

abnormal example the thorax is sinuate at the sides in front, and the elytra are not

punctured at the apex, and have the setiferous impressions partly obliterated.

There is an example of this species in Mr. F. Bates’s collection, from that of Dejean,

labelled Statira megatoma *, and as from the United States ; this locality is doubtless

erroneous.

36. Statira punctipennis.

Elongate, moderately shining, varying in colour from piceous to obscure reddish-brown ; the elytra with a

more or less distinct eencous lustre, more shining at the apex, and usually darker than the prothorax.

Head sparsely and finely punctured, and often shallowly foveate in the centre between the eyes, the

latter small and very widely separated in both sexes; antenne piceo-ferruginous or ferruginous, mode-

rately stout—the apical joint in the male rather shorter than joints 7-10, in the female 8-10, united ; pro-

thorax comparatively broad, transverse, the sides sharply margined from the base to the apex, a little

rounded anteriorly (sometimes almost straight in front), and strongly constricted behind, the hind angles

acute, the basal margin sharply raised, and at the sides deeply grooved within, the disc shallowly trans-

versely depressed in the middle behind, the surface finely, very irregularly, and somewhat closely punctured

(often subscabrous or aciculate in places between the punctures) ; elytra with long and deep intrahumeral

depression, long, finely and deeply punctate-striate, the punctures crowded and transverse in shape from

the base to about the middle, and finer and shallower towards the apex, the interstices flat or feebly

convex, thickly and shallowly, but distinctly, punctured (the punctures deeper towards the apex), the first

with two or three (at the apex), the third and fifth each with one or two (widely separated, and between

the middle and apex), the seventh with one (at the shoulder), and the ninth with two or three (near the

apex), fine shallow setiferous punctures, the apices obtuse; beneath obscure reddish-brown, shining ;

legs varying in colour from piceous-brown to piceo-testaceous, rather stout.

Length 9-10 millim. ; breadth (at shoulders) 23-27 millim. (d ¢ -)

Hab. Guatemata, Capetillo (Champion).

Numerous examples. In this species the head is finely and sparsely punctured ; the

eyes are small and very widely separated ; the thorax is transverse, broad, and sharply

margined at the sides; and the elytra are long, rather deeply striate (the punctures

transverse in shape), and have the interstices thickly punctured (very shallowly so to

beyond the middle, and more deeply so at the apex), the first, third, fifth, and ninth each

with two or three very shallow setiferous impressions. The thorax varies a good deal

in sculpture, and the setiferous elytral impressions are sometimes obsolete. S. puncti-

pennis is closely allied to S. enco-tincta, but may be distinguished by its very widely

separated eyes, broader and more sharply margined thorax, punctured elytral interstices,

fewer setiferous impressions, &c. |

37. Statira testacea.

Very elongate, opaque, reddish-testaceous, the prothorax sometimes suffused with piceous ; the elytra shining,

obscure testaceous, sometimes with a faint «neous lustre. Head densely and roughly punctured ; the

STATIRA. 29

eyes black, small, and widely separated; antenne ferruginous or testaceous, rather slender, moderately

long—the apical joint in the male about as long as joints 7-10, in the female 8-10, united; prothorax

narrow, about as long as or longer than broad, the sides finely margined from the base to the apex,

feebly rounded anteriorly (sometimes almost straight in front), and moderately constricted behind, the

hind angles acute, the basal margin moderately raised, the entire surface finely and very densely scabrous ;

elytra with rather deep intrahumeral depression, long, finely punctate-striate, the punctures approximate

and transverse in shape to beyond the middle, the interstices flat or feebly convex, sometimes obsoletely

punctured at the apex, the first with two or three (at the apex), the third with from six to eight and the

fifth with four or five (scattered between the base and apex), the seventh with two or three (one at the

shoulder and one or two at the apex, the latter often obsolete), and the ninth with from five to eight

(scattered between the base and apex, the anterior ones often obsolete), rather deep setiferous punctures,

the apices obtuse; legs slender, more or less testaceous.

Length 73-94 millim.; breadth (at shoulders) 2-24 millim. (¢ 9.)

Hab. Mexico, Jalapa (Hége), Cordova (Sallé, Hoge).

Numerous examples. S. testacea is closely allied to S. eneotincta, but constantly

differs in its uniformly scabrous and quite opaque thorax. As in S. mexicana, the

setiferous impressions are sometimes obliterated on the apical part of the seventh

interstice. :

Var. a. The elytra testaceous, the base very broadly, or the sides to about the middle, piceous.

Hab. Guatemata, Cubilguitz (Champion).

Var. 3. Piceous- or reddish-brown, the elytra varying in colour from piceous-brown to fusco-testaceous ; the

prothorax a little more dilated at the sides before the middle, the anterior angles not so prominent; the

head not so closely, punctured.

Hab. GuaTEMALA, San Gerénimo, near the city, Capetillo (Champion).

This species is not uncommon in Mexico and Guatemala; from Nicaragua a single

example only has been received. The form described by Maklin, of which we have

two from the Sallé collection, is an immature variety in which the elytra are pallid

testaceous, and the four or five setiferous impressions on the third and fifth, and the

‘two or three on the first and ninth, interstices are fuscous in colour; one of these is

figured. Asin many other species of this genus, the colour is very variable: in all

our other specimens the elytra are unicolorous, or, at most, as in the var. a, stained

with piceous at the base ; in rare dark-coloured individuals they have a faint translucent

greenish-eneous tinge. 4. nigrosparsa is a moderately elongate species, with the head

more or less roughly punctured (opaque in some examples, slightly shining in others) ;

the antenne in the male with the apical joint equalling four or five, in the female

about three or four, of the preceding joints united; the thorax margined at the sides,

30 HETEROMERA.

with prominent front angles, and the surface finely scabrous and opaque; and the

elytra rather deeply punctate-striate. The apical joint of the antenne varies a little

in length in both sexes. The variety 8 was collected by myself in numbers at Capetillo ;

in some of these the elytral interstices are obsoletely punctured at the apex. The

species varies from 8-11 millim. in length. 9. nigrosparsa differs from S. rugicollis

and S. guatemalensis in its more finely scabrous thorax and ungrooved tibie, and from

the former in the much less numerous setiferous impressions on the elytra; the two

last-mentioned species having sulcate tibie they are placed towards the end of the

genus.

39. Statira penicillata. (Tab. II. fig. 3, 3.)

Closely allied to S. testacea, and differing as follows:—Reddish-testaceous ; the prothorax not so densely

scabrous, slightly shining ; the elytral interstices strongly convex (except at the base), the first with about

eight (four at the base and four at the apex), the third and fifth each with twelve or fourteen (scattered

between the base and apex), the seventh with one or two (at the shoulder), and the ninth with four or

five (towards the apex), deep setiferous punctures; the posterior tibie in the male with a dense brush of

very short hairs on the inner side near the base ; the rest as in S. testacea.

Length 9 millim.; breadth 24} millim. (¢.)

Hab, Mexico, Jalapa (Hége).

This is the only species of the genus known to me possessing the peculiar above-

described sexual character on the posterior tibie in the male. Unfortunately our male

examples of S. testacea are in a mutilated condition and without hind legs; they may

or may not possess this character. SS. pentcillata differs, however, from S. testacea in

the much more numerous setiferous impressions on the first, third, and fifth elytral

interstices, and also in all the interstices being very convex. A single male example.

40. Statira alternans.

Elongate, subparallel, subopaque, reddish-brown, the elytra obscure testaceous and slightly shining. Head

densely and rugosely punctured, the eyes large ; antenne long and stout, ferruginous, the apical joint in

the male about as long as joints 5-8 united; prothorax transverse, broad, the sides distinctly margined

from the base to the apex, a little rounded before the middle, slightly oblique in front, and strongly

constricted behind, the hind angles very acute, the basal margin sharply raised, and at the sides shallowly

grooved within, the disc a little flattened behind, the surface finely scabrous ; elytra with shallow intra-

humeral depression, long, rather broad, parallel, closely and finely punctate-striate, the interstices flat,

the first, third, fifth, seventh, and ninth each with a row of rather closely placed deep setiferous punctures,

extending from the base to the apex, the apices obtuse ; legs testaceous, rather stout, somewhat thickly

punctured and clothed on all sides with short hairs, the tibiee not grooved on their outer edge.

Length 11 millim.; breadth 3 millim. (¢.)

Hab. Mexico, Tepansacualco (Sallé).

A single immature male example only, but undoubtedly distinct from the other

species here enumerated. In many respects S. alternans resembles S. sulcicrus. It

differs as follows:—The tibia are not grooved on their outer edge; the antenne (<¢ )

are longer, and have a longer apical joint; the eyes are larger; the thorax is more

distinctly margined, broad, and transverse ; and the elytra are broader and more parallel,

and have the interstices flat, the setiferous impressions on the alternate ones deeper

and not quite so numerous. S. alternans is also allied to S. leptotracheloides, but more

distantly.

41. Statira tuberosa. (‘'ab. II. fig. 4, 2 .)

Very elongate, depressed, opaque, obscure reddish-brown, the elytra piceo-testaceous with a brassy lustre, and

not quite so dull. Head finely and rather thickly punctured, the eyes (@) large; antenne obscure

testaceous, rather slender, the apical joint in the female about as long as joints 8-10 united ; prothorax

rather longer than broad, the sides finely margined from the base to the apex, rounded anteriorly, and

strongly constricted behind, the hind angles acute, the basal margin sharply raised, the surface almost

smooth (under a very strong lens a few minute scattered punctures are visible); elytra with long and

shallow intrahumeral depression, very long and depressed, widest beyond the middle, subparallel ante-

riorly, with rows of fine shallow punctures placed upon very shallow striz, the punctures approximate

towards the base, but becoming more scattered and finer towards the apex, the interstices quite flat, the

first, third, and fifth each with from ten to twelve (scattered between the base and apex), and the seventh

and ninth each with from six to eight (one at the base and the others between the middle and apex),

very shallow setiferous punctures, the punctures from the middle to the apex each preceded by a small

conical elevation, the apices obtuse; beneath piceo-testaceous, shining ; legs long and slender, obscure tes-

taceous, the knees a little darker.

Length 10 millim.; breadth (at shoulders) 23 millim. ( 2.)

Hab. Mexico, Jalapa (Hége).

One female example only. Allied to S. nodulosa, but differing in the thorax being

smoother, and with the anterior angles not prominent, and in the elytra having not

nearly so many setiferous punctures on the alternate interstices, the tubercles preceding

the punctures more conical, and not becoming elongate towards the apex, and the striz

more finely and less closely punctured. <S. tuberosa closely resembles S. wneotincta ;

it is, however, ready distinguished by the opaque thorax and tuberculate elytra.

42. Statira nodulosa.

Very elongate, rather depressed, dull piceo-castaneous, the elytra with a greenish-zneous lustre and slightly

shining. Head finely and somewhat thickly punctured ; eyes (¢) very large, rather narrowly separated ;

antenne (¢ ) ferruginous, long, the apical joint equalling joints 6-10 united ; prothorax about as long as

broad, the sides finely but distinctly margined from the base to the apex, rounded about the middle,

strongly constricted behind, and sinuate-emarginate in front, the anterior angles sharply defined and pro-

jecting laterally, the hind angles acute and very prominent, the basal margin much raised, and grooved

within towards the sides, the disc shallowly transversely impressed in the middle behind, the surface

very minutely, shallowly, and somewhat thickly punctured ; elytra with long intrahumeral depression,

very long, widest beyond the middle, finely punctate-striate, the punctures very closely placed, the inter-

but differs in its finely and closely punctured head, very much larger eyes, very long

apical joint to the antenne, sharp anterior angles of the thorax, the punctures of the

alternate elytral interstices not preceded bya tubercle, &c. ‘The sharp and prominent

anterior angles of the thorax and the tuberculate elytra are characteristic of S. nodulosa.

\ 48, Statira tuberculifera, (Tab. I. fig. 5, 2.)

\Very elongate, rather depressed, dull piceous-black, the elytra seneous and slightly shining. Head finely and

rather thickly punctured ; eyes ( 2) very large; antennee ( 9 ) ferruginous, long, the apical joint not quite

so long as joints 7-10 united; prothorax as long as broad, the sides very distinctly margined from the

base to the apex, a little rounded about the middle, strongly constricted behind, and sinuate-emarginate

in front, the anterior angles sharply defined and projecting laterally, the hind angles acute and very

prominent, the basal margin much raised, the disc a little flattened in the middle behind, the surface

shallowly, minutely, and somewhat thickly punctured; elytra with long intrahumeral depression, very

elongate, widest beyond the middle, finely punctate-striate, the punctures closely placed, the interstices flat

towards the base, slightly convex towards the sides and apex, the first, third, fifth, seventh, and’. ninth

each with a row of closely placed setiferous punctures, the setiferous punctures (except at the base) each

preceded by a very distinct conical elevation, and the elevations themselves becoming elongate and strongly

raised towards the sides and apex, those on the seventh interstice confluent at the base and forming a

sharp longitudinal keel at the shoulder, the apices sharply pointed ; beneath piceous-black, smooth, very

shining ; legs long, rather thickly punctured, the femora sparsely pubescent, the tibiae somewhat densely

clothed with short hairs within.

Hab. GuateMata, Coban (Conradt).

A single female example. S. tuberculifera is closely allied to 8. nodulosa, but may

easily be distinguished by the tubercles of the elytra being much more raised and also

larger in size, those on the seventh interstice forming a sharp keel at the shoulder; the

apices of the elytra are also more pointed.

(Sailé), Chontales (Janson) ; Panama, Volcan de Chiriqui 3000 feet (Champion).

This is one of the commonest and most widely distributed species of Statira inhabiting

Central America; it may be known by its small size, shining surface, and reddish-testa-

ceous colour, the elytra each with two large oblong yellowish spots, the spots each sur-

rounded by a fuscous or piceous line. In a long series of examples (about 100) the insect

shows a good deal of variation in the elytral markings:—The form described by Maklin

has the two oblong spots on each elytron narrowly edged with fuscous (the insect thus

coloured almost exactly resembling certain species of Huproctus, a genus of Carabide

STATIRA. 33

numerously represented in the same region) ; in another, the fuscous or piceous colour

occupies the whole of the space between the spots and extends to the base (this form

much resembling the European Dromius quadrimaculatus, Linn.); and in another (two

examples from Capetillo), the anterior spot extends to the base and the posterior one

to the apex, and the markings are thus limited to a common transverse fuscous band a

little behind the middle, the fuscous colour extending anteriorly and posteriorly along

the suture, and also in a similar way at the sides. In avery rare variety from Chiriqui

the anterior spot is shortened and the posterior one much enlarged, and the base is

broadly piceous, the posterior spot extending laterally upwards and only separated

from the anterior one by a curved piceous line (fig. 7). All these numerous varieties

are connected by intermediate examples, though the extreme forms look totally different.

The apical joint of the antenne in the male equals about four, in the female rather

more than three, of the preceding joints united. The species varies from 5-7 millim.

in length. Numerous allied forms inhabit Tropical South America. We figure two

examples, both from Chiriqui.

This very distinct species was found in plenty by Herr Hoge at Jalapa; it will be readily

identified from our figure. The apical joint of the antenne in the male is fully as long

as five, in the female four, of the preceding joints united. &. pulchella is apparently*

confined to the Atlantic slope of Central Mexico. Allied forms inhabit Tropical South

America.

46. Statira nigromaculata. (Tab. II. figg. 9, ¢ ; 10, var. 2.)

Moderately elongate, testaceous, shining, the elytra with a lateral patch about the middle (varying in size,

sometimes small, sometimes very large, and almost confluent at the suture, and only separated by a very

narrow line), and the eyes, black or piceous. Head very minutely punctured between the eyes, and with

a deep setiferous impression behind each, for the rest smooth, the eyes small; antenns testaceous, rather

short—the apical joint in the male equalling joints 7-10, in the female 8-10, united ; prothorax convex,

about as long as broad, the sides immarginate (sometimes obsoletely margined towards the base), rounded

anteriorly, and strongly constricted behind, the hind angles acute, the basal margin moderately raised

and grooved within, the surface very minutely and somewhat thickly punctured; elytra with long and

deep intrahumeral depression, widest beyond the middle, finely and lightly punctate-striate, the interstices

flat, but becoming convex towards the apex, the third with five or six (between the middle and apex), the

seventh with one (at the shoulder), and the ninth with three or four (near the apex) setiferous punctures,

the apices obtuse ; legs and under surface entirely testaceous.

34 HETEROMERA.

Five examples.. §&. nigromaculata is undoubtedly very closely allied to 8. pulchella ;

but in the large series of the latter before me the common transverse black mark of

the elytra shows no tendency to become obliterated. In the Guatemalan specimen

(fig. 10) the lateral spots are extended inwards, and form a common broad median band

(separated only by a narrow line along the suture) which is widest outwardly; the

example from Yolos is intermediate between this one and the others. S. negromaculata

differs from 8. pulchella in the head and thorax being still more finely punctured, the

apical joint of the antenne shorter in the male, and the elytral interstices convex

towards the apex, as well as in the different pattern of the elytra.

47. Statira triangulifer. (Tab. II. fig. 11, 2.)

Moderately elongate, shining, testaceous, the elytra with a common triangular patch at the base and another

a little beyond the middle (the latter varying in size, but always broadest at the suture, and sometimes

extending to the lateral margin, and sometimes narrowly continued along the suture to the scutellar

patch and posteriorly towards the apex), and the eyes, black or piceous. Head very minutely punctured

between the eyes, and with a deep setiferous puncture behind each, for the rest smooth, the eyes small;

antenne testaceous, rather long—the apical joint in the male about equalling joints 7-10 (the latter elongate),

in the female 8-10, united ; prothorax convex, about as broad as long, the sides immarginate, rounded ante-

riorly, and strongly constricted behind, the hind angles acute, the basal margin moderately raised, the

surface thickly but very minutely punctured ; elytra with very shallow intrahumeral depression, widest

beyond the middle, finely but rather deeply crenate-striate, the interstices flat or feebly convex, the third

and ninth (and sometimes the fifth) with one or two setiferous punctures towards the apex, and the

seventh with one at the shoulder, the apices obtuse ; legs and under surface entirely testaceous.

Length 63-7 millim, ; breadth 13-13 millim. (¢ 9.)

Hab. Mexico, El Camaron (Sal/é), Tapachula in Chiapas (Hége); British Honpuras,

Belize, R. Hondo (Blancaneaur); Guatemala, Panzos, San Gerdnimo, Zapote

(Champion).

This insect is not uncommon in Guatemala and British Honduras, but is apparently

rarer in Mexico. WS. triangulifer is allied to S. pulchella, but differs in its narrower

shape, smoother thorax, longer antenne, and crenate-striate elytra, the latter differently

marked—in S. pulchella the common basal patch is broader and more transverse, and

the second band is always broadest laterally, instead of at the suture, as in S. triangu-

lifer. The head and thorax in S. pulchella are invariably of a reddish-testaceous

colour, these parts in. S. ériangulifer being uniformly testaceous; the intrahumeral

depression of the elytra is also more deeply impressed in S. pulchella, and the latter has

more setiferous impressions on the third interstice.

48. Statira evanescens. (Tab. II. fig. 12, ¢.)

Moderately elongate, slightly shining, testaceous or reddish-testaceous, the elytra with the shoulders, a common

triangular, or elongate, scutellar patch (often connected along the base with the humeral one, in one example

obsolete), and a median patch on each (more or less transverse in shape, and varying greatly in size—

sometimes extending nearly to the suture, and connected by a narrow line with the scutellar marking,

and sometimes entirely obsolete), and the eyes, piceous or black. Head with exceedingly minute scattered

punctures, and a setiferous impression behind each eye, the latter small; antenns testaceous, rather

short, the apical joint in the male about equal to joints 7-10, in the female 8-10, united ; prothorax about

as long as broad (in some examples shorter), the sides obsoletely margined, rounded anteriorly, and strongly

constricted behind, the hind angles acute, the basal margin very little raised, and at the sides grooved

within, the surface smooth, or with exceedingly minute scattered punctures ; elytra with long and rather

shallow intrahumeral depression, widest beyond the middle, finely punctate-striate (in some examples sub-

crenately so), the interstices flat, but becoming convex towards the apex, the first with one or two (near

the apex, sometimes obsolete), the third with about four (between the middle and apex), the fifth some-

times with one or two (towards the apex), the seventh with one (at the shoulder), and the ninth with

three or four (at the apex), fine setiferous punctures, the apices obtuse; beneath testaceous, the venter in

dark-coloured examples piceous ; legs entirely testaceous.

Var. The elytra (the epipleure excepted) piceous, the suture sometimes a little lighter.

Hab. Muxico, Cuernavaca (Sallé, Hoge). Four examples.

This species is widely distributed and not uncommon in various parts of Mexico.

It varies a great deal in the coloration of the elytra, but in the typical form the

shoulders are always piceous; in some examples the entire base is black or piceous,

and the median patch on each elytron large in size; in the variety the elytra are

piceous. The typical form of &. evanescens approaches S. pulchella, 8. nigromaculata,

&c., but it may be distinguished by the differently-arranged elytral markings, obsoletely

margined thorax, and other particulars noted above. It also varies considerably in

size. The variety resembles S. vilis, from which it may be distinguished by its almost

smooth head and thorax and other particulars.

49, Statira vereecrucis. (Tab. II. fig. 13, 2.)

Moderately elongate, subopaque, reddish-testaceous ; the elytra slightly shining, testaceous, each with a piceous

lateral stripe (sinuous on its inner edge) extending from immediately below the shoulder to a little beyond

the middle and there directed inwards. Head rugosely punctured; the eyes small, black; antenns

rather short, testaceous, the apical joint (2 ) equalling joints 8-10 united ; prothorax broader than long,

not very convex, the sides obsoletely margined, gradually and obliquely converging anteriorly, and strongly

and abruptly constricted behind, the anterior angles rather prominent, the hind angles acute, the basal

margin very little raised, and at the sides grooved within, the disc slightly flattened behind, the surface

densely scabrous and opaque ; elytra with shallow intrahumeral depression, widest beyond the middle,

finely but rather deeply punctate-striate, the interstices flat on the disc and at the apex, a little convex

towards the sides, the first with one (near the apex), the third with six and the fifth with four (widely

scattered between the base and apex), the seventh with one (at the shoulder), and the ninth with four

51. Statira picta, (Tab. II. fig. 14, 2.)

Moderately elongate, slightly shining, testaceous; the elytra each with a narrow stripe extending from

the shoulder to a little below the middle and there connected with a transverse angulated band (the

latter not reaching the suture), or with the lateral stripe narrower and shorter (almost obliterated in one

example) and a small transverse marking on each, piceous or fuscous. Head with a few exceedingly

minute scattered punctures, and a setiferous impression behind each eye, the latter small; antenne

testaceous or ferruginous, the apical joint in the male about equalling joints 7-10, in the female 8-10,

united; prothorax convex, about as long as broad, the sides immarginate, rounded anteriorly, and strongly

constricted behind, the hind angles acute, the basal margin very little raised, the surface with exceedingly

minute scattered punctures; elytra with shallow intrahumeral depression, widest about the middle, very

shallowly and finely punctate-striate, the interstices flat throughout, the first with one or two (near the

apex), the third with five or six (scattered between the base and apex), the fifth with two (towards the

apex), the seventh with one (at the shoulder), and the ninth with three or four (towards the apex), fine

setiferous punctures, the apices obtuse ; legs and under surface testaceous.

pion).

Three specimens only. This is the smallest of the species allied to & evanescens

&c. inhabiting Central America. The example with best-defined elytral markings

(from Nicaragua) resembles 8. verecrucis, from which its small size, almost smooth

and immarginate thorax, and smooth head distinguish it. The flat apical interstices of

the elytra and other characters mentioned above separate it from §. nigromaculata.

52. Statira albolineata. (Tab. II. fig.15, ¢.)

Elongate, slightly shining; the head piceous- or reddish-brown; the prothorax yellowish-white, with a

large, oblong, purplish-brown patch on each side of the disc about the middle; the elytra of a dilute

brownish colour, or brownish-testaceous, the fifth interstice and the epipleuree white or yellowish-white

throughout. Head with a few setiferous punctures behind, for the rest almost smooth, shallowly, longi-

of the disc and a narrow space within the apical margin almost smooth ; elytra with very shallow intra-

humeral depression, long, coarsely crenate-striate, the interstices convex, the fifth costate, considerably

broader than either of the others, and white or yellowish-white in colour, the first and third with a

Length 8-9 millim.; breadth 2-21 millim. (3.)

Hab. Mexico, Tuxtla (Sallé); Nicaragua, Chontales (Janson).

Two examples only, both males. This species has quite a different facies from any

other Statira known to me. In the fifth elytral interstice being costate and broader

and lighter in colour than either of the others, S. albolineata somewhat resembles

certain species of Diabrotica. ‘The thorax has a large, oblong, purplish-brown rugose

patch on each side. The elytra are coarsely crenate-striate, with convex interstices.

The example from Tuxtla is figured.

53. Statira corrosa.

Moderately elongate, shining, thickly clothed with short erect hairs ; the head piceous, testaceous in front, the

prothorax reddish-testaceous, the elytra obscure violaceous or bluish-black. Head coarsely punctured ;

the eyes somewhat convex, moderately large ; antenne piceous or piceo-ferruginous (the basal joint some-

times lighter), moderately stout, very long (fully reaching to the middle of the elytra) in the male, shorter

in the female, the apical joint in the male nearly as long as joints 7-10, in the female less than 8-10,

united ; prothorax convex, about as long as broad, the sides immarginate, rounded anteriorly, and mode-

rately constricted behind, the hind angles moderately prominent, the basal margin rather sharply raised,

the surface very coarsely, deeply, and rather closely punctured ; elytra with shallow intrahumeral depres-

sion, moderately long, finely punctate-striate, the interstices flat to beyond the middle, convex at the apex,

and finely, shallowly, and irregularly punctured (more sparsely so towards the apex), the apices obtuse ;

beneath varying in colour, sometimes with the venter and part of the head piceous and the rest reddish-

testaceous, and sometimes the under surface of the prothorax alone of the latter colour, shining, the venter |

thickly punctured ; legs clothed on all sides with long erect hairs, rather slender, varying in colour,

Hab. Guatemata, Las Mercedes (Champion). One male example.

This species varies very much in size and colour. It is chiefly distinguished from its

allies by its coarsely punctured head and thorax, long antenne in the male, thickly and

confusedly punctured elytral interstices, and hairy legs. S. corrosa in its elytral

sculpture and hairy legs resembles S. brevipilis ; but it differs from that species in its

less elongate shape, more prominent eyes, more slender antenne, shorter thorax, different

colour, &c.

54, Statira horrida. (Tab. II. fig. 16, ¢.)

Elongate, rather convex, subopaque, blackish-violaceous, the prothorax reddish-testaceous, the body above and

beneath thickly clothed with moderately long erect ashy hairs. Head coarsely and rugosely punctured,

shallowly grooved on each side between the eyes anteriorly, the latter moderately large; antenne rather

stout, moderately long, piceous, the apical joint ( 2 ) not so long as joints 8-10 united; prothorax convex,

about as long as broad, the sides immarginate, rounded anteriorly, and strongly constricted behind, the

hind angles moderately prominent, the basal margin grooved within, the surface coarsely and rather

closely punctured ; elytra with very shallow intrahumeral depression, rather long, subparallel to beyond

the middle, very coarsely and deeply punctate-striate, the punctures very closely packed and strongly

transverse to beyond the middle and thence to the apex crenate, the interstices quite narrow, moderately

convex to about the middle, strongly so beyond, and finely and confusedly punctured, the apices obtuse ;

beneath piceous, shining, somewhat thickly punctured; legs rather long, piceous, thickly clothed with

long erect ashy hairs.

Length 74 millim.; breadth 2 millim. ( 9.)

Hab. Guatemata, Panzos in Vera Paz (Champion).

A single female example, captured by myself in the lower part of the Polochic valley.

S. horrida resembles S. corrosa, the head and thorax being somewhat similarly shaped

and punctured, but differs greatly in the sculpture of the elytra and also in the upper

and under surfaces and legs being much more thickly clothed with long erect hairs.

The rows of punctures on the basal half of the elytra are closely packed and very

strongly transverse, and the interstices in consequence quite narrow, the latter being

confusedly punctured.

55. Statira punctatissima.

Moderately elongate, rather dull, brownish-piceous, thickly clothed with short erect hairs, the prothorax and

the front of the head testaceous, the elytra subopaque and with the shoulders and the suture (narrowly)

testaceous. Head coarsely and closely punctured, the eyes moderately large; antenne ( ¢) long, fusco-

ferruginous, the basal joint testaceous, the apical joint nearly as long as joints 7-10 united ; prothorax

convex, about as long as broad, the sides immarginate, rounded anteriorly, and strongly constricted

behind, the hind angles moderately prominent, the basal margin raised, the surface very coarsely, deeply,

and rather closely punctured, a longitudinal space on the middle of the disc smooth; elytra with shallow

intrahumeral depression, moderately long, finely punctate-striate, the punctures closely packed and deep,

the interstices flat at the base, rather convex at the apex, and very closely and confusedly punctured

throughout, the apices obtuse ; beneath thickly punctured, testaceous, the venter piceous; legs compara-

tively slender, thickly clothed on all sides with rather long erect hairs, testaceous, the knees stained with

_ piceous.

Length 6 millim.; breadth 14 millim. (¢.)

Hab. Mexico, Tapachula in Chiapas (/ége).

A single male example, captured on the lower part of the South Mexican Pacific slope.

This species is closely allied to S. corrosa, but may be identified by its less shining

surface and the very thickly and more distinctly punctured elytral interstices. From

S. horrida the much more finely punctured elytral strie (the punctures similar in shape

throughout and not strongly transverse on the basal half) sufficiently distinguish it.

56. Statira brevipilis.

Elongate, narrow, nigro-eneous, shining, the elytra dark cyaneous (in one example piceous-brown with a

cyaneous lustre), the surface clothed with short erect hairs. Head very coarsely punctured, the eyes

small; antennee piceous, very stout, rather long—the apical joint in the male longer, in the female shorter,

than joints 8-10 united; prothorax longer than broad, cylindrical, the sides immarginate, only a little

rounded anteriorly, and feebly constricted behind, the hind angles moderately prominent, the basal margin

very little raised, the surface very coarsely and deeply punctured, the punctures more scattered on the

disc; elytra with rather shallow intrahumeral depression, long, coarsely and deeply punctate-striate

throughout, the interstices almost flat and coarsely and thickly punctured (two or three very irregular

rows on each), the punctures finer than those of the strie and rather shallow, the apices obtuse; beneath

black or piceous, shining, very sparsely and coarsely punctured, the punctures each bearing a short sub-

erect hair; legs piceous or piceo-ferruginous, roughly punctured, and somewhat thickly clothed with rather

long suberect hairs.

Length 74-84 millim.; breadth 17-2} millim. (¢ Q.)

Hab. Mexico, Jalapa (fége).

Four examples, two of each sex. A narrow, elongate species, blackish-eeneous in

colour and shining; the elytra dark cyaneous, coarsely punctate-striate, and with the

interstices coarsely and thickly punctured, the punctures each bearing a short erect

hair; the head and thorax very coarsely punctured, the latter immarginate at the sides ;

the eyes small; and the legs roughly punctured and pilose.

57. Statira villosa.

Closely allied to S. brevipilis and differing as follows :—The antenne not so stout ; the prothorax more sparsely

and still more irregularly punctured ; the elytra dark cyaneous, the interstices each with a very irregular

row of coarse (but shallow) closely placed punctures, the punctures each bearing a moderately long erect

hair ; the femora and tibie thickly clothed with long erect hairs.

Length 9 millim.; breadth 27 millim. ( 9.)

We have received specimens of all the forms (except 5) of this variable species from

Cuernavaca, not only from M. Sallé but also from Herr Hoge. S. nigripennis is dis-

tinguished from the allied species by its narrow and very elongate shape, shining hairy

surface, black or piceous head, reddish thorax, and (in the typical form) bluish-black

or nigro-gneous elytra. The head is comparatively narrow (and owing to the long and

prominent labrum appears very elongate), and has a few coarse setiferous punctures

between the eyes and at the base ; the eyes are rather small and oblique ; and the antenne

are rather long, and have the apical joint in the male longer, in the female shorter,

than joints 8-10 united. The thorax is convex, rather longer than broad, immarginate

laterally, and has (except on the middle of the disc) a few scattered coarse punctures.

The elytra are long, and finely and rather deeply punctate-striate ; the interstices are

flat at the base but become convex towards the apex, and each has an irregular row of

rather closely placed setiferous impressions extending from the base to the apex. The

femora and tibie on all sides are clothed with long scattered erect hairs.

In the Sallé collection S. nigripennis is separated into five species, though all are

from the same locality and differ in nothing except colour. S&S. nigripennis varies from

7-9 millim. in length and from 12-24 millim. in breadth.

59. Statira nigrosnea. (Tab. II. fig. 19, 3, var.)

Elongate, narrow, nigro-sneous, shining, the surface clothed with moderately long erect hairs. Head with

scattered very coarse punctures, the eyes moderately large; antenne not very stout, piceous, the apical

joint in the male longer, in the female less, than joints 8-10 united; prothorax convex, about as long as

broad, the sides immarginate (or obsoletely margined at the extreme base), rounded anteriorly, and

moderately constricted behind, the hind angles not very prominent, the basal margin very little raised,

the disc sometimes a little depressed in the middle before the base, the surface with very coarse widely

scattered punctures; elytra with rather shallow intrahumeral depression, long; very coarsely and closely

punctate-striate, the interstices flat, but becoming very convex towards the apex, each with an irregular

row of coarse setiferous impressions (coarser than the punctures of the striz), the apices obtuse; legs

piceous, the femora and tibiz clothed with moderately long erect hairs.

Length 7-93 millim.; breadth 13-24 millim. (9.)

Hab. Mexico, Ventanas in Durango (Hége).

Var. a. The two basal joints of the antenne, the prothorax, the under surface (except the venter), and the

basal two-thirds of the femora and of the tibise reddish-testaceous. (¢-)

Var, B. The elytra each with a broad stripe from the shoulder to the apex and the epipleure testaceous; the

rest asina. (¢.) (Fig. 19.)

Hab. Mexico, Ventanas in Durango (fdége).

Three female examples of the type, and a male of each of the varieties. ‘The coarser

and very much deeper punctuation of the elytra (especially of the interstices) and their

nigro-eneous colour readily distinguish this species from 8. brevipilis and S. villosa.

The thorax is more sparsely punctured, the antennz more slender, and the eyes larger

than in S. brevipilis, and the elytral interstices have one row of coarse setiferous impres-

sions only. The punctures of the elytral interstices are much coarser and deeper

(compared with those of the striz) than in 8. véllosa, though they are similarly arranged.

S. setigera is another closely allied and similarly-coloured species. ‘The var. «resembles

S. nigripennis, Makl., but differs from it in the punctures of the head and thorax being

coarser and much more numerous and those of the elytral stria and interstices much

coarser and deeper.

60. Statira setigera.

Elongate, narrow, parallel, piceous-black, shining, the elytra nigro-seneous. Head comparatively broad, with

some fine widely scattered punctures and three coarse widely separated setiferous impressions on each side

close to the inner margin of the eyes, the latter ( ¢ ) small, the comparatively broad space behind them

with numerous coarse setiferous punctures ; antenne moderately long, stout, brownish-piceous—the apical

joint (¢) the length of joints 8-10 united, 10 much longer than broad; prothorax convex, longer than

broad, the sides immarginate, arcuate anteriorly, and strongly constricted behind, the hind angles pro-

minent, the basal margin moderately raised but scarcely grooved within, the surface with a few very

coarse punctures towards the sides posteriorly and for the rest smooth ; elytra with shallow intrahumeral

depression, long and parallel, shallowly striate, the strie with closely placed rather coarse punctures

which become finer towards the apex, the interstices flat, each with an irregular row of closely placed

moderately coarse setiferous punctures extending from the base to the apex, those on the second and the

eighth interstice more scattered and much fewer in number, the apices obtuse; beneath brownish-black,

very shining, the ventral segments each with three or four setiferous punctures only on each side; legs

rather slender, piceous, the femora and tibiee clothed on all sides with long erect scattered hairs.

Length 94 millim.; breadth 27 millim. (<¢.)

punctures, the femora and tibie on all sides with erect sete, and the thorax immar-

ginate laterally, this species approaches S. cribrata ; it differs, however, in its nigro-

eeneous colour, quite small eyes, shorter and stouter antenne (the apical joint much less

elongate in the male), more coarsely punctured elytra, &c. The head and thorax are

similarly, but more sparsely punctured than in S. cribrata; and the ventral segments

have only three or four setiferous punctures on each side. The very much smoother

head and thorax, and the flat interstices and much more finely and shallowly punctate-

striate elytra distinguish S. setigera from S. nigrownea, to which it is in other respects

closely allied.

61. Statira cribrata. (Tab. II. fig. 20, ¢.)

Very elongate, depressed, varying in colour from brownish-piceous to obscure testaceous, the elytra of a trans-

lucent seneous tint, shining. Head with very coarse scattered setiferous punctures, the epistoma and

labrum also with a few coarse punctures; eyes large, smaller in the female; antenne long and rather

stout, more or less ferruginous—the apical joint in the male about as long as joints 7-9 united (8-10

rather elongate, decreasing in length outwardly, 10 shorter than 9 but much longer than broad), in the

female as long as 7 and 8 united ; prothorax about as long as or rather longer than broad, the sides im-

marginate, moderately rounded anteriorly, and constricted behind, the hind angles not acute though rather

prominent, the basal margin raised and shallowly grooved within, the surface with very coarse and deep

widely scattered setiferous punctures; elytra with shallow intrahumeral depression, long and depressed,

subparallel to the middle, finely and very closely punctate-striate, the interstices flat or feebly convex,

each with a row of closely and irregularly placed fine setiferous punctures extending from the base to the

apex, the apices rather obtuse ; the entire under surface (the middle of the metasternum excepted) with

scattered coarse setiferous < uiichanes: and varying in colour from brownish-piceous to testaceous; legs

long and slender, varying from brownish-piceous to testaceous, the femora and tibie on all sides clothed

with long hairs.

Hab. GuateMaua, near the city (Salvin), Duenas (Salvin, Champion), Calderas

7000 feet (Champion).

Seven examples, four males and three females. A very distinct species, and easily

recognized by the upper and under surfaces and the femora and tibie on all sides being

rather thickly clothed with long erect hairs; the head and thorax bear very coarse and

deep scattered punctures, and the elytral interstices each a row of fine and rather

closely (but irregularly) placed setiferous impressions; the ventral segments (instead of

having, as usual, a few setiferous punctures on each side) have punctures scattered over

the greater part of their surface.

62. Statira ciliata. (Tab. II. fig. 21, ¢.)

Very elongate, depressed, dull reddish-castaneous ; the elytra shining, bright greenish-eneous with golden and

cupreous tints towards the sides, the suture very narrowly castaneous. Head with a few (two only on

each side between the eyes and a few behind) very coarse and very deep punctures, the epistoma and

labrum with a few fine ones; eyes ( ¢) comparatively small, widely separated ; antenne very long, rather

slender, ferruginous—the apical joint in the male the length of joints 7-9 united, 8 and 9 long and sub-

equal, 10 shorter than 9 but much longer than broad; prothorax moderately convex, about as long as

the sides with scattered coarse deep punctures (much finer than those on the head), the basilar groove

rather closely punctured, the disc impunctate; elytra with shallow intrahumeral depression, very long,

subparallel to beyond the middle, depressed on the disc, very closely and finely punctate-striate, the

punctures not quite extending to the apex, the interstices flat, the first, third, fifth, seventh, and ninth

wider and each with a row of. closely and irregularly placed setiferous punctures (the third with two

irregular rows) extending from the base to the apex, the punctures coarse and deep on the seventh and

ninth and fine and shallow on the other interstices, the apices rather obtuse ; the entire under surface (the

middle of the metasternum excepted) with somewhat closely placed coarse setiferous punctures ; legs long

and slender, ferruginous, the femora and tibie clothed on all sides with long hairs.

Length 10 millim.; breadth 22 millim. (¢.)

‘Hab. Guatemata, San Gerdénimo 3000 feet (Champion).

A single male example. This species is allied to 8. cribrata. It differs from it in

having the alternate elytral interstices only with setiferous punctures, those on the

two outer interstices being very coarse and deep; and the head and thorax sub-

opaque and with fewer punctures (those on the head much coarser and very few in

number), the disc of the latter being impunctate. As in S. cribrata the upper and

under surfaces and the femora and tibie on all sides are rather thickly clothed with long

erect hairs.

63. Statira pilipes. (Tab. II. fig. 22, 2.)

Moderately elongate, depressed, piceo-testaceous, shining, the elytra with a translucent purplish tinge which

changes to greenish-wneous at the base. Head closely, coarsely, and deeply punctured posteriorly and

between the eyes, the latter (Q) small and widely separated ; antenna ( @ ) ferruginous, long and slender

—the apical joint not so long as joints 8-10 united, the latter elongate ; prothorax about as long as broad,

the sides immarginate, a little rounded about the middle, almost straight in front, and moderately constricted

behind, the hind angles acute, the basal margin moderately raised, the entire surface coarsely, deeply and

closely punctured, the punctures separate one from another ; elytra with shallow intrahumeral depression,

rather broad, comparatively short, widest beyond the middle, crenate-striate, the punctures approximate and

transverse from the base to about the middle, the interstices moderately convex throughout, the first, third,

fifth, seventh, and ninth each with a very irregular row of closely placed setiferous punctures extending

from the base to the apex, the apices obtuse ; legs slender, obscure testaceous, the femora and tibiz on all

sides, and the tarsi above, somewhat thickly clothed with long erect hairs.

Length 74 millim.; breadth (at shoulders) 2 millim. (.)

Hab. Mexico, Tapachula in Chiapas ({6ge).

This species is not closely allied to any other described here. Its chief characters

are :—The long and slender antenne; the coarsely and deeply punctured head and

thorax (the punctures quite separate one from another), the latter immarginate; the

depressed and comparatively short elytra, with crenate strize and convex interstices, the

alternate interstices each with an irregular row of closely placed setiferous punctures ;

and the femora and tibie clothed on all sides with long erect hairs. S.. pilipes

approaches S. ciliata and S. cribrata in many of its characters.

V 64, Statira marmorata. (Tab. II. fig. 23, ¢.)

setiferous impressions, the eyes moderately large; antenne ferruginous or testaceous, rather long and

slender—the apical joint in the male the length of joints 8-10 (these latter elongate), in the female 8 and 9,

united; prothorax convex, about as long as broad, the sides obsoletely margined towards the base, rounded

anteriorly, and moderately constricted behind, the hind angles subacute, the basal margin very little raised,

the surface rather uneven and subcoriaceous and with scattered very coarse setiferous impressions, the

interspaces usually with some finer punctures ; elytra with shallow intrahumeral depression, long, finely

and closely punctate-striate, the interstices flat, the first, third, fifth, seventh, and ninth each with a row

of rather closely placed setiferous punctures, the apices obtuse; beneath testaceous, shining ; legs long

and slender, testaceous, the femora and tibiz on all sides clothed with long erect hairs.

Length 53-9 millim.; breadth (at shoulders) 13-23 millim. (¢ 9.)

Hab. Mexico, Jalapa (Hoge); GuatemMaua, Cerro Zunil (Champion).

Found in abundance by Herr Hoge, sparingly by myself. This species is allied to

S. cribrata and S. ciliata, but, apart from colour-differences, abundantly distinct. In

all the specimens received the elytra are testaceous and mottled to a greater or less

extent with piceons. |

65. Statira microps. (Tab. II. fig. 24, ¢.)

Moderately elongate, testaceous, shining. Head with widely scattered shallow setiferous impressions, the space

between the eyes also closely and minutely punctured, the eyes black, very small and convex, and distant

from the base ; antennz testaceous or fusco-testaceous, long, moderately stout—the apical joint in the

male a little longer than joints 9 and 10 united (the latter elongate), not shorter in the female; pro-

thorax convex, about as long as or rather longer than broad, the sides immarginate, rounded anteriorly,

MALA, San Isidro, Zapote (Champion).

Numerous examples. A shining testaceous species, with very long set, quite small

eyes, hairy legs, smooth immarginate thorax, and coarsely sculptured elytra, the alternate

interstices of which each bear a row of somewhat closely placed setiferous impressions.

The elytra are smoother towards the apex, and the head bears scattered shallow seti-

ferous impressions in addition to the usual punctures.

66. Statira albofasciata. (Tab. II. fig. 25, 3.)

Moderately elongate, comparatively convex, shining, violaceous or bluish-black ; the prothorax testaceous or

reddish-testaceous ; the elytra each with a transverse band below the base (broadly widened on the middle

smooth ; eyes quite small, transverse, and distant from the base of: the head; antenne moderately stout,

varying in colour from piceous to ferruginous, the apical joint often lighter—the latter in both sexes

only a little longer than joints 9 and 10 united; prothorax transversely convex, broader than long (some-

times about as long as broad), the sides completely immarginate, much rounded anteriorly, and strongly

constricted behind, the hind angles moderately prominent, the basal margin grooved within and raised, the

Hab. Mxxico, Playa Vicente, Cordova (Sallé), Atoyac in Vera Cruz (H. H. Smith) ;

GUATEMALA, Cahabon (Champion); Panama, Bugaba (Champion).

Var. The elytra with the yellowish-white bands much more extended, and leaving only the base narrowly

(except at the suture), a narrow sinuous transverse band before the middle (not reaching the suture), a

broader transverse lateral patch beyond the middle, and the apices, violaceous ; the epipleure yellowish-

white.

Hab. Mexico, Playa Vicente (Sad/é). One specimen only.

We have lately received numerous examples of this elegant insect from Atoyac,

where it appears to be not uncommon. ‘Two specimens only were found in Guatemala,

and one in the State of Panama. S. albofasciata has much the facies of one or two

species of Lema inhabiting the same districts. It agrees very closely in many respects

with Maklin’s description of S. trifasciata, from Colombia. The elytra, however, in

the latter are stated to have three black fasciee which reach the suture and not the

lateral margins, a system of coloration not exhibited in any of the varieties of S. aldo-

fasciata. The Central-American species, moreover, invariably has the apex of the

elytra bluish-black. A typical example from Atoyac is figured.

67. Statira irregularis, (Tab. II. fig. 26, var.)

Moderately elongate, shining, thickly clothed with erect hairs; the head brassy-black, the prothorax red or

reddish-testaceous, the elytra cyaneous or bluish-black. Head with scattered setiferous punctures at the

base, sides, and in front, for the rest almost smooth, and shallowly depressed on each side between the

eyes anteriorly; the latter transverse, quite small, and distant from the base of the head; antenne’

rather stout, black or piceo-ferruginous, the apical joint sometimes lighter—the latter about as long as

joints 9 and 10 united, and scarcely longer in the male; prothorax transversely convex, broader than

long, the sides immarginate, much rounded, and strongly constricted behind, the hind angles moderately

prominent, the basal margin grooved within and raised, the disc (except at the base and apex) very finely

and shallowly canaliculate (sometimes very obsoletely, and sometimes rather deeply so in the centre), the

surface quite smooth; elytra with prominent shoulders, moderately long, with rows of fine punctures

extending to the apex, but more or less interrupted or irregular towards the base, the interstices quite

flat throughout, with scattered punctures (similar to those of the strie) towards the base, and each with

a very irregular row of rather closely placed setiferous impressions (many of which are more or less

confluent with those of the striz), the apices obtuse; beneath (the prothorax excepted) brassy-black,

shining; legs rather short, bluish- or brassy-black, the femora more or less reddish-testaceous at the base,

the femora and tibie on all sides thickly clothed with long, erect hairs, the tibie roughly punctured.

Length 52-64 millim.; breadth 13-13 millim. (¢ 9.)

Hab. Guatemaa, San Gerénimo 3000 feet (Champion).

Var. a. The elytra each with a somewhat oblique yellow or yellowish-white band extending from a little

below the shoulder to about one fifth from the apex and there turning off abruptly and obliquely to

the lateral margin (broadly interrupted posteriorly in one example); the basal two-thirds of the venter

reddish-testaceous. (Fig. 26.)

Hab. Guatemaa, San Gerénimo (Champion).

Var. 8. Above and beneath black, the elytra bluish-black.

Hab. Guatemata, Chinautla 4100 feet (Salvin).

Numerous examples of the type-form and of the var. a were collected together by

myself at San Gerdnimo: the var. 6 only differs in having the prothorax black.

S. irregularis is closely allied to 8. albofasciata; but, apart from colour-differences,

it may be at once distinguished by the more coarsely punctured elytra (the punctures |

not only of the strie, but of the interstices also, much deeper and more distinct and

continued to the apex) and the (usually) finely canaliculate thorax. The elytra are

more or less confusedly punctured towards the base. In one example of the var. « the

longitudinal band of the elytra is broadly interrupted posteriorly. The short, trans-

versely convex thorax, very small eyes, less elongate shape, &c. distinguish S. irregularis

and its allies from the other similarly-coloured species inhabiting Central America *.

68. Statira levicollis. (Tab. III. fig. 1.)

Moderately elongate, shining; the head brassy-black, the prothorax reddish- or flavo-testaceous, the elytra

cyaneous or bluish-black, with the suture from a little below the base (or from the middle) to the apex

yellowish-white. Head, eyes, antenne, and prothorax much as in S. trregularis; the prothorax with, at

most, a short fine impressed line on the middle of the disc (usually obsolete), and the disc impressed in the

centre at the base; the elytra with rows of closely packed, rather coarse, punctures placed upon shallow

strie, the punctures extending to the apex, the interstices flat, slightly convex towards the apex, and each

with a very irregular row of rather coarse and quite closely placed setiferous punctures (many of which

are more or less confluent with those of the striz) which extend to the apex, the apices obtuse; ‘beneath

(the head and prothorax excepted) varying in colour from brassy-black to reddish-testaceous, the venter

in light-coloured examples piceous at the apex only; legs rather short, roughly punctured, bluish- or

brassy-black, the femora usually more or less (sometimes broadly) testaceous at the base, the femora and

tibie thickly clothed on all sides with long, erect hairs.

Length 53-77 millim.; breadth 13-2 millim. (¢ 9.)

Hab. Mexico, Colima city, Chilpancingo (/6ge).

Var. The elytra unicolorous bluish-black.

Hab. Mexico, Colima city (Hége).

* In Mr. F. Bates’s collection there is a species of Statira closely allied to this labelled Pedilus sanguinicollis,

Dej. (Dej. Cat. 3rd edit. p. 237), and as from the United States. This insect is possibly of Mexican origin; but

in the absence of a more certain locality, it is inadvisable to describe it here.

STATIRA. AT

Many examples of the type and one of the variety were captured by Herr Hoge at

Colima city, and one only at Chilpancingo. 8. Jevicollis (in the form with unicolorous

elytra) much resembles S. érregularis; it differs from it, however, in the elytral strie

being more deeply impressed (especially noticeable at the apex) and more coarsely

punctured, and the setiferous impressions of the interstices still more numerous and

deeper. The prothorax is quite smooth, and sometimes shows traces of a fine impressed

line on the middle of the disc. The yellowish-white sutural stripe occupies the first

(and sometimes part of the second) elytral interstice. The under surface is sometimes

wholly reddish-testaceous, except the head and the apex of the venter.

69. Statira minima. (Tab. III. fig. 2, 2.)

Elongate, narrow, shining; the head black, with a slight brassy tinge, the prothorax red or reddish-testaceous,

the elytra piceous-brown. Head with numerous rather coarse setiferous punctures, the eyes small ;

antenne black or piceous, stout—the apical joint in the male the length of joints 8-10 united, scarcely

shorter in the female; prothorax transverse, strongly so in the female, convex, the sides immarginate,

much rounded anteriorly, and strongly constricted behind, the hind angles acute, the basal margin raised,

the surface with exceedingly minute scattered punctures (only visible under a strong lens); elytra with

shallow intrahumeral depression, long, subparallel in their basal half, with rows of rather coarse punc-

tures placed upon very shallow strie, the punctures finer and more scattered and the stria deeper towards

the apex, the interstices flat, feebly convex towards the apex, and each with a very irregular row of

scattered setiferous punctures (extending from the base to the apex, and the punctures here and there

confluent with those of the striz), the apices obtuse; beneath in great part piceous, the prothorax more

or less reddish-testaceous, the sides of the venter broadly flavous; legs short, piceous, the extreme base of

the femora testaceous, the femora and tibia on all sides clothed with erect hairs.

Var. The prothorax and entire under surface eeneo-piceous, the femora testaceous at the extreme base.

Length 43-5 millim.; breadth 1-13 millim. (do Q.)

Hab. Nicaracua, Chontales (Janson); Panama, Bugaba, Volcan de Chiriqui, Caldera,

David (Champion).

Numerous examples from Chiriqui, one only from Nicaragua. This very small

narrow species has much the facies of an Anthicus ; as in many other Statire, there

are two forms of it, one with the thorax red and the other with the thorax piceous.

Allied species inhabit Southern Colombia. The oral organs are formed as in the

other species of the genus.

70. Statira bicolor. (Tab. III. fig. 3, ¢ .)

Moderately elongate, flavo- or reddish-testaceous, shining; the elytra black from about the basal third nearly to

the apex, the black band widest at the suture and with its anterior and posterior margins oblique. Head

with a few setiferous impressions behind the eyes, and also a few in front, for the rest smooth, depressed

on each side between the eyes anteriorly, the latter black, small; antenne piceous, the basal and the apical

one or two joints pallid testaceous, rather long—the apical joint in the male about as long as the five, in

the female rather longer than the three, preceding joints united; prothorax transversely convex, broader

than long, the sides completely immarginate, much rounded anteriorly, and very strongly constricted

behind, the hind angles sharp and prominent, the basal margin grooved within and raised, the surface

quite smooth, the disc sometimes obsoletely canaliculate in the middle; elytra with rather deep intra-

humeral depression, moderately long, widest beyond the middle, with rows of fine punctures placed upon

very shallow strie, the punctures not very closely placed, more scattered beyond the middle, and almost

obsolete towards the apex, the interstices quite flat throughout, the alternate ones, 1, 3, 5, 7, 9, each with

a row of fine scattered setiferous punctures which extend from the base to the apex, the apices obtuse ;

beneath wholly testaceous, shining; legs moderately long, testaceous, the tibie and tarsi piceo-testaceous,

the femora glabrous and almost smooth, the tibia clothed with very short hairs within.

Length 6-7 millim.; breadth 13-2 millim. (¢ 2.)

Hab. Panama, Bugaba 1000 feet (Champion).

Four examples, three males and one female. This very distinct species is not closely

allied to any other known to me; in size and general shape it approaches S. albo-

fasciata, but differs totally in the structure of the antenne, and also in the legs being

almost smooth, and not clothed with long erect: hairs.

71. Statira rugicollis.

Elongate, opaque, blackish-brown, the head (in part) and the elytra fusco-castaneous, the latter slightly

shining, the oral organs and epistoma reddish-testaceous. Head densely and rugosely (but shallowly)

punctured, the punctures longitudinally confluent, the eyes large; antenne moderately long, stout,

ferruginous—the apical joint (¢) as long as joints 6-10 united, the penultimate joint rather short ;

prothorax about as long as broad, the sides margined from the base to the apex, moderately rounded

before the middle, strongly constricted behind, and sinuate-emarginate in front, the anterior angles

prominent and projecting laterally but obtuse, the hind angles acute, the basal margin very little raised

and not grooved within, the disc flattened posteriorly, the surface very densely and rugosely (but quite

shallowly) punctured, the punctures longitudinally or sinuously confluent; elytra with shallow intra-

humeral depression, moderately long, subparallel anteriorly, finely and rather closely and deeply punctate- —

striate, the punctures transverse in shape, the interstices almost flat from the base to the middle, a

little convex beyond, the first, third, and fifth each with about twelve (scattered between the base and

apex), the seventh with four or five, and the ninth with about eight, rather coarse setiferous punctures,

the apices obtuse; legs obscure testaceous, moderately stout, sparsely and roughly punctured, and clothed

with very short hairs, the tibie towards the apex grooved on their outer edge.

Length 9 millim.; breadth 23 millim. (¢.)

Hab. Mexico, Jalapa (Hoge).

One male example. This species may be identified from the allied forms by its

rugose head and thorax, the latter having the anterior angles prominent, and a distinct

lateral margin from the base to the apex; the tibie are shallowly grooved towards the

apex on their outer edge; the apical joint of the antenne in the male is as long as

joints 6-10 united. S. rugicollis and S. guatemalensis have the head and thorax more

coarsely sculptured than in any other species of the genus here enumerated.

72. Statira guatemalensis.

Closely resembling S. rugicollis, the head and prothorax very similarly shaped and sculptured, but with the

anterior angles of the latter not so prominent, and also differing as follows :—The upper surface reddish-

brown, the elytra obscure piceo-testaceous; the penultimate joint of the antenne in the male longer, the

apical joint (3) not equalling joints 6-10 united; the elytra more elongate, the first interstice with two

or three (at the apex), the third with eight and the fifth with six (widely scattered hetween the base and

apex), the seventh with one (at the shoulder), and the ninth with from four to six (one at the shoulder

and very shallowly grooved on their outer edge; the rest as in S. rugicollis.

Length 10 millim.; breadth 3 millim. (¢.)

Two male examples, agreeing precisely with each other. This insect is allied to

S. rugicollis, but differs in having the setiferous punctures of the alternate elytral

interstices very much fewer in number, and one only (at the shoulder) being present

on the seventh; the elytra are relatively longer; the ninth and tenth joints of the

antenne (d¢) are more elongate; and the tibie are more shallowly grooved on their

outer edge. SS. guatemalensis is still more closely allied to S. nigrosparsa; but it may

be distinguished by its more coarsely scabrous thorax, and by having several more

setiferous impressions on the third and fifth elytral interstices, and the tibie shallowly

grooved on their outer edge.

73. Statira asperata. (Tab. III. fig. 4,¢.)

Moderately elongate, piceous- or reddish-brown, shining. Head with a shallow punctured foveate depression in

the middle between the eyes, for the rest smooth, the eyes moderately large; antenn fusco-ferruginous or

ferruginous, stout, comparately short—the apical joint in the male nearly as long as joints 6-10 united

(10 as broad as long), but little shorter in the female; prothorax a little longer than broad, convex, the

sides obsoletely margined towards the base, rounded anteriorly, and strongly constricted behind, the hind

angles acute, the basal margin feebly raised, the surface almost smooth; elytra with long and deep intra-

humeral depression, moderately elongate, widest at the middle, and thence to the apex gradually narrowing,

finely and shallowly punctate-striate, the interstices almost flat on the basal part of the disc and convex

towards the sides and apex, the first, third, fifth, seventh, and ninth with a row of closely placed setiferous

punctures which are each preceded by a rather distinct conical elevation, the elevations towards the sides

and apex becoming elongate in shape, the apices rather sharp; legs piceo-ferruginous or ferruginous,

sparsely pubescent, the tibie grooved towards the apex on their outer edge. ,

Length 6-74 millim.; breadth 2-23 millim. (¢ 2.)

Hab. Panama, Volcan de Chiriqui, Caldera, San Feliz (Champion).—VENEZUELA,

Cumana (coll. F. Bates).

Four examples. This species is not closely allied to any other here enumerated.

Its chief characters are the short and stout antenne, smooth head and thorax, the

former foveate in the middle between the eyes, and the latter almost immarginate,

tuberculate and rather ovate elytra, grooved tibie, and comparatively short form. The

setee of the body are very long. The femora and tibiz are quite sparsely clothed with

very short decumbent hairs.

74. Statira multipunctata. (Tab. III. fig. 5, 3.)

Elongate, depressed, opaque, reddish-brown, the elytra not quite so dull. Head scabrous, the eyes (¢ ) small;

antenne long and stout, ferruginous—the apical joint in the male about the length of joints 8-10 united,

the latter elongate; prothorax about as long as broad, the sides finely margined from the base to the apex,

moderately rounded anteriorly, and strongly and abruptly constricted behind, the hind angles acute and

very prominent, the basal margin sharply raised and at the sides shallowly grooved within, the surface

finely scabrous; elytra with shallow intrahumeral depression, long and depressed, widest beyond the

middle, finely and closely punctate-striate throughout, the interstices flat towards the base but feebly —

convex towards the apex, each with a row of closely placed coarse setiferous punctures (the sete very

long) extending from the base to the apex, the apices obtuse ; beneath piceous-brown, shining, the ventral

segments on each side and the metasternum with numerous setiferous punctures; legs ferruginous or

testaceous, the femora and tibis roughly and rather closely punctured and clothed on all sides with short

hairs, the tibie on their outer edge deeply sulcate from the base to the apex.

Length 9-10 millim.; breadth (at shoulders) 23-3 millim. (d.-)

Hab. Mexico, Cuernavaca (Sal/é).

Two male examples. In having all the elytral interstices from the base to the

apex furnished with closely placed setiferous punctures, S. multipunctata approaches

S. cribrata; but there the comparison ends, the two species not being otherwise closely

related. WS. multipunctata is distinguished from the allied forms by the above-men-

tioned character, and also by its scabrous head and thorax, the latter with very acute

hind angles, hairy and roughly punctured legs, very deeply suleate tibie, and opaque

reddish-brown colour.

75. Statira hirsuta. (Tab. III. fig. 6, 3.)

Moderately elongate, rather depressed, clothed with very long erect hairs, opaque, reddish-brown or reddish-

testaceous, sometimes suffused (the elytra especially) with piceous, the elytra not quite so dull. Head

(including the epistoma) scabrous, the eyes rather small; antenne more or less ferruginous, rather long

and stout—the apical joint in the male a little longer, in the female rather less, than joints 8-10 united ;

prothorax broader than long, sometimes a little longer, flattened on the disc, the sides feebly margined,

strongly rounded anteriorly, and deeply constricted be lind, the hind angles very acute, the basal margin

moderately raised and at the sides deeply grooved jwithin, the surface densely scabrous; elytra with

shallow intrahumeral depression, moderately long, widest beyond the middle, very finely and shallowly

punctate-striate, the interstices feebly convex behind and flat towards the base, the alternate ones (1, 3,

5, 7, 9) each with a row of closely placed shallow setiferous punctures (the sete very long) extending from

the base to the apex, the apices obtuse; beneath reddish-brown or reddish-testaceous, very shining; legs

moderately stout, varying in colour from piceo-testaceous to testaceous, the apical half of the femora often

darker, the femora and tibie roughly punctured and clothed on all sides with long suberect hairs, the

tibize sulcate on their outer edge from the base to the apex.

Length 7-93 millim.; breadth (at shoulders) 2-2$ millim. (¢ @.)

Hab. Mexico (coll. F. Bates), Jalapa, Iguala in Guerrero, Tapachula in Chiapas

(Hoge); Nicaraava, Chontales (Belt).

Found in plenty by Herr Hoge at Jalapa. A moderately elongate, hirsute, dull

reddish-brown or reddish-testaceous species, with the head and thorax scabrous, the

latter much rounded at the sides anteriorly and rather depressed on the disc, the elytra

very shallowly and finely punctate-striate and with the alternate interstices furnished

with numerous setiferous impressions, the legs rough and setose, and the tibie sulcate

on their outer edge. 8. hirsuta is less elongate than S. multipunctata, and has a

shorter thorax and the alternate interstices only of the elytra furnished with setiferous

impressions; from §. swlcicrus it may be distinguished by its rougher, shorter, and

more depressed thorax, more finely and shallowly punctured elytral striz, less setose

body, and less elongate shape.

STATIRA. 51

An immature example (from Mexico), in Mr. F. Bates's collection, labelled S. apicalis,

Dej., has the apical half of the elytra stained with fuscous. The sete in this species

are very long, not only on the body but on the legs also.

76. Statira pueblensis. (Tab. III. fig. 7, 2 .)

Elongate, rather depressed, subparallel, shining, piceous-black, the elytra with an indistinct brassy tint. Head

thickly, irregularly, and somewhat coarsely punctured, shallowly foveate in the middle between the eyes,

the latter (2) rather small; antenne (9 ) fusco-ferruginous, darker towards the base, exceedingly stout,

moderately long—the apical joint nearly as long as joints 8-10 united, the latter much longer than broad ;

prothorax rather longer than broad, moderately convex, the sides very finely margined from the base to

the apex, a little rounded about the middle, slightly oblique in front, and strongly constricted behind, the

hind angles sharp and prominent, the basal margin moderately raised and at the sides shallowly grooved

within, the disc shallowly depressed in the middle behind, the surface densely, finely, and irregularly

punctured and wrinkled; elytra with indistinct intrahumeral depression, long, subparallel to beyond the

middle, a little flattened on the disc, finely punctate-striate, the punctures closely packed and subtrans-

verse, the interstices flat on the basal part of the disc and moderately convex at the sides and towards the

apex, the first, third, fifth, seventh, and ninth each with a row of closely placed setiferous punctures

which extend from the base to the apex, the apices obtuse; legs stout, fusco-ferruginous, the femora

darker, the tibia sparsely clothed with short hair within and without and grooved on their outer edge

from the base to the apex, the femora on all sides with long scattered hairs.

Length 10} millim.; breadth 3 millim. ( 9.)

Hab. Mexico, Matamoros Izucar in Puebla (Hoge).

One female example only. In its very stout antenne this species approaches S. cras-

sicornis, though totally different in other respects. S. pueblensis may be separated from

the other Central-American Statire with grooved tibie by its stout limbs and more

shining surface. JS. ¢ristis, Makl. (according to the description), approaches S. pueblensis

in many of its characters.

77. Statira sulcicrus.

Elongate, rather narrow, subopaque, piceo-castaneous or brownish-piceous, the head, and sometimes the pro-

thorax, redder in colour. Head scabrous, the epistoma smoother, the eyes moderately large and widely

separated in both sexes; antenne fusco-ferruginous, moderately long, rather slender—the apical joint in

the male about as long as joints 7-10, in the female 8-10, united; prothorax longer than broad, the sides

obsoletely margined from the base to the apex, rounded anteriorly, and moderately constricted behind, the

basal margin a little raised, the hind angles acute, the surface very finely scabrous; elytra with very

shallow short intrahumeral depression, long, widest a little beyond the middle, finely punctate-striate, the

punctures transverse and closely packed, the interstices feebly convex from the base to the middle and

more strongly so beyond, the first, third, fifth, seventh, and ninth each with a row of closely placed deep

setiferous punctures extending from the base to the apex, the apices slightly produced but obtuse; legs

moderately stout, piceous or fusco-ferruginous, the tibis grooved on their outer edge from the base to

the apex, the femora and tibie on all sides clothed with short scattered hairs,

Length 93-94 millim.; breadth 23-23 millim. (¢ 2.)

Hab. Mexico, Chilpancingo in Guerrero (Hége).

Duller than S. pueblensis; the antenne not nearly so stout; the head and thorax

finely scabrous and opaque, &c. Asin S. pueblensis, the tibiee are grooved on their outer

edge froin the base to the apex, and the alternate elytral interstices have each a row of

closely-placed setiferous impressions. S. pluripunctata, Horn, from Arizona, appears

to be allied to this species; but, unlike any of the Mexican Statire with grooved tibiz,

it is stated to have the sides of the thorax without a distinct edge even at the base.

Four examples, two of each sex.

78. Statira rugipes.

Very elongate, depressed, picéous-black, opaque, the elytra not so dull. Head very irregularly and closely

punctured, scabrous between the eyes, the latter large but rather widely separated ; antenne ( 9 ) ferru-

ginous, rather short, moderately stout, the apical joint about as long as joints 8-10 united; prothorax as

long as broad, the sides obsoletely margined throughout, moderately rounded anteriorly, and constricted

behind, the hind angles rather sharp, the basal margin a little raised, the surface densely and finely

scabrous; elytra with shallow intrahumeral depression, very long, finely punctate-striate throughout, the

punctures transverse and approximate, the interstices rather convex, except on the basal part of the disc,

and the first, third, fifth, seventh, and ninth each with a row of closely placed setiferous punctures

extending from the base to the apex, the apices obtuse; beneath piceous-black, shining ; legs long, rather

slender, piceous, the tarsi ferruginous; the femora and tibiee roughly punctured, the former on all sides

thickly clothed with long, and the tibia within with shorter, decumbent hairs; the tibie deeply grooved

on their outer edge from the base to the apex.

Length 12% millim.; breadth 33 millim. (2.)

Hab. Mexico, Ventanas in Durango (Hodge).

One female example only. Larger and more elongate than S. sulcicrus, the elytra

relatively much longer, the antenne considerably stouter than in the corresponding sex

of that species, the thorax still more densely scabrous and very opaque, and the femora

more roughly punctured.

The narrowly ovate apical joint of the labial palpi and the much longer third joint

of the antenne distinguish S. rugipes from either of the species of Hpicydes.

79. Statira leptotracheloides. (Tab. III. fig. 8, 2 .)

Elongate, narrow, subparallel, depressed, subopaque, obscure reddish-testaceous, the elytra testaceous and not

so dull. Head scabrous between the eyes, the latter (9) black and quite small, the comparatively broad

space behind them with fine scattered setiferous punctures ; antenne long, moderately slender, testaceous—

the apical joint (@) not so long as joints 8-10 united, the latter elongate; prothorax narrow, subcylin-

drical, longer than broad, the sides obsoletely margined at the base and apex, moderately rounded

anteriorly, and not very strongly constricted behind, the hind angles acute, the basal margin moderately

raised and scarcely grooved within, the surface very finely scabrous; scutellum finely punctured ; elytra

with indistinct intrahumeral depression, long, flattened on the disc, closely, finely, and shallowly punctate-

striate, the interstices flat, the first, third, fifth, seventh, and ninth each with a row of closely placed deep

setiferous punctures, the apices a little produced but obtuse; beneath reddish-testaceous, slightly shining ;

legs testaceous, moderately long, the femora and tibiw sparsely and roughly punctured and clothed on all

sides with rather long decumbent hairs, the tibiz from the base to the apex grooved on their outer edge.

Length 94 millim.; breadth 23 millim. (9.)

Hab. Mzxico, Ventanas in Durango (fHége).

An immature female example only. Closely allied to S. sulctcrus; but differing in

STATIRA.—UROPLATOPSIS. 53

its much smaller eyes (the space behind them being quite broad, instead of narrow as

in the same sex of S. sulcicrus), longer penultimate joints to the antenne in the female

(the apical joint, comparatively, not so long as in the same sex of S. sulcicrus), relatively

narrower thorax, and deeper and still more numerous setiferous punctures on the

elytral interstices. SS. leptotracheloides, S. sulcicrus, &c., form a small group of species

which are chiefly confined to North-west Mexico and the adjacent country beyond the

United-States frontier. S. leptotracheloides closely resembles Leptotrachelus puncti-

collis, a species of Carabide (cf. Biol. Centr. Am., Col. i. pt. 1, p. 159, t. vi. fig. 18).

The following species is unknown to me, and owing to the imperfect description

it cannot be properly placed in the arrangement here adopted :—

80. Statira tristis.

Statira tristis, Makl. Act. Soc. Fenn. x. p. 639°.

Hab. Mexico 1.

I am unable to identify this insect amongst the large number of Mexican Statire

before me. The species representing it in the Sallé collection is 8. nigripennis, Makl.

WS. tristis is described as being very elongate, black, and moderately shining; the

antenne very robust; the prothorax much rounded at the sides anteriorly, with the

surface faintly rugulose and very slightly shining; the elytra transversely depressed

below the base, and with the alternate interstices seriately punctured. To judge from

Maklin’s description, S. tristis would appear to have the thorax shaped much as in

S. hirsuta, i. e. rotundate-dilate anteriorly; the thorax of S. pueblensis cannot be thus

described. In the structure of the antenne and in the elytral sculpture (as given by

-Maklin), S. tristis resembles S. pueblensis.

UROPLATOPSIS.

Last joint of the maxillary palpi elongate-triangular, that of the labial palpi narrow and ovate and with its

apex truncate ; ligula moderately prominent, rounded on each side, and emarginate in the middle in front ;

mentum trapezoidal, transverse ; outer lobe of the maxille rather narrow; mandibles simply uniden-

tate at the apex; labrum very large and prominent; antenne with joints 3-10 large and more or less flat-

tened and dilated, very broadly so in some species, and angularly widened on each side towards their apex,

7 and 8 the widest, 11 very long in both sexes, and usually about half the width of the apex of 10; head

narrow, abruptly constricted into a neck behind; eyes convex, small, or only moderately large, somewhat

distant from the base of the head ; elytra with or without an opaque velvety lateral patch; anterior coxe

strongly exserted, narrowly separated, the prosternum raised between them ; metasternal episterna almost

unimpressed, and without well-defined groove along the inner margin ; tibiw without distinct spurs.

54 HETEROMERA.

Numerous species from the southern part of Central America, and one from Tropical

South America‘, agree well in the above-mentioned characters, and they form a well-

defined genus f{. All these species bear a striking resemblance to certain Lycide and

Hispide, more especially to the latter, and all are exceedingly rare. In one species,

U. mimica, the elytral sculpture, antennal structure, &c. is here reproduced in a very

similar manner to that existing in the genus Uroplata and other Hispidw. The oral

organs are formed very much as in Séatira, though the antenne exhibit a very different

structure. The elytra are sculptured as in many genera of Lycide and Hispide.

U. appendiculata possesses a most remarkable sexual development in the male, the hind

femora being furnished with a large hollow pouch beneath, and the anterior tibiz toothed,

and the intermediate tibie twisted; U. simulans is also furnished with well-marked male

characters. Two groups of species are indicated, one without, the other with an opaque

velvety patch (not interrupting the striz) on each side of the elytra about the middle.

The seven species captured by myself in the State of Panama were found upon leaves in

the forest.

* Hlytra without opaque lateral patch,

1. Uroplatopsis imitator. (Tab. III. figg. 9, ¢ ; 9a, labium; 94, maxilla

and maxillary palpus; 9 ¢, mandible.)

Elongate, clothed with a few scattered erect hairs, opaque; reddish-ochraceous, the eyes, the scutellum, and

the suture very narrowly, for a short distance, piceous. Head longitudinally grooved between the eyes,

+t Uroplatopsis nodosa,

Elongate, narrow, opaque, brownish-piceous, the head (except the eyes), the atkins at the sides, the elytra

at the shoulders, and a narrow band across the middle and another at the apex of the femora, flavous,

the elytra with a perfectly opaque black patch on each side about the middle. Head slightly depressed

between the eyes, and with some coarse setiferous impressions between and behind them; antennz black,

the apical joint and the greater part of the second testaceous, joints 3-10 rather broadly flattened and

dilated, 7 and 8 the widest, 11 rather longer than 8-10 united; prothorax about as long as broad, the

sides immarginate, rounded anteriorly, and abruptly constricted immediately before the base, the disc with

three broad transverse smooth elevations on each side, the elevations separated one from another by

deep transverse grooves and down the middle by a longitudinal one running from the base to the apex,

the basal margin raised, the hind angles prominent, the surface smooth; elytra with smooth humeral

callus, long and parallel, rather depressed, with regular rows of deep coarse impressions from the base to

the apex, the interstices narrow and raised, the apices obtuse ; femora smooth and glabrous; tibia clothed

on all sides with long erect hairs.

Length 63 millim.; breadth 13 millim.

Hab. Amazons, Ega (H, W. Bates).

A single example of this species, apparently a female, is contained in Mr. F. Bates’s collection.

+ In a closely allied undescribed genus, of which two or three species were captured by Mr. H. W. Bates

on the Amazons (these being now contained in his brother’s collection), the apical joint of the labial palpi is

_ broad and has its apical side shallowly emarginate, the femora are clavate, and the metasternal episterna have

a very deep groove along the whole length of their inner margin. These species have the antenne formed as

in Uroplatopsis, and also agree closely in all other respects.

UROPLATOPSIS. 5d

coarsely rugose along the middle, the epistoma smoother, the base with very coarse scattered setiferous

impressions, a narrow convex space along each side of the inner margin of the eye and the orbits smooth,

the eyes convex ; antenne fusco-ferruginous or fusco-piceous, the basal joints darker, joints 3-10 very

broadly flattened and each angularly dilated towards the apex, 7 and 8 the widest, 3 very much narrower

and shorter than 4, 11 longer than 8-10 united; prothorax longer than broad, slightly and somewhat

obliquely narrowed in front and (if viewed from the side) strongly constricted behind, obsoletely margined

at the sides, with a sinuous, smooth, shining, raised space on each side extending from the base to the

apex (the true lateral margin placed almost beneath this, and posteriorly scarcely visible from above), the

broad space enclosed flat, and, like the sides, very rugosely punctured, the hind angles very prominent,

the basal margin broad and much raised ; elytra long, rounded at the shoulders, the sides almost straight

from a little below the base to beyond the middle, very deeply punctate-striate throughout, the inter-

stices each with a double (the sutural with one) row of very closely-packed granules which extend to

the apex, the fifth and ninth nearly to the apex (the fifth sharply), and the seventh at the base, costate

and smoother, and closely and transversely notched on each side, the apices each armed with a sharp

triangular tooth within; beneath varying in colour from piceous-brown to testaceous, with the venter

partly piceous, the sides of the metasternum coarsely punctured ; legs piceous-brown or piceo-testaceous,

the femora testaceous towards the base, the latter smooth and glabrous, the tibiee clothed with long

hairs.

Length 10 millim.; breadth 24 millim. (¢.)

Hab. Nicaraeua, Chontales (Belt).

Two specimens only. JU. imitator resembles U. planicollis, and has the thorax

similarly shaped and sculptured ; it differs, however, in its larger size, still more broadly

dilated antenne, the groove between the eyes broader and rugose within, the fifth

elytral interstice sharply (the third not) costate, and also in the smooth and glabrous

femora.

2. Uroplatopsis vermiculata. (Tab. III. fig. 10, ¢.)

Elongate, clothed with a few scattered erect hairs, opaque; reddish-ochraceous, the head in front, the eyes, the

neck, a narrow stripe down the middle of the prothorax, the scutellum, the suture for a short distance,

and the apical two-fifths of the elytra black or brownish-black. Head with numerous very coarse seti-

ferous punctures, coarsely rugose in front, and grooved in the middle between the eyes, the latter convex ;

antenne and prothorax as in U. imitator; elytra as in U. imitator, but with the double rows of granules

of the interstices replaced on the dark-coloured apical portion by crowded minute granular points, the

fifth and the ninth interstices nearly to the apex, and the seventh at the base, costate, the apices each

armed with a sharp triangular tooth within ; beneath more or less piceous at the sides, the venter in part

testaceous; legs as in U. imitator.

Length 9 millim.; breadth 23 millim. (<¢.)

Hab. Nicaracua, Chontales (Belt).

Two male examples. Rather smaller than U. imitator, the thorax with a longitudinal

stripe down the middle and the apical two-fifths of the elytra black or brownish-black ;

the interstices of the dark apical portion of the elytra sculptured in a ‘different manner

to the rest of the surface, the double rows of granules being replaced by crowded

minute granular points. In this last-mentioned character U. vermiculata resembles

U. reticulata, in which the dark-coloured portion of the elytra is differently sculptured

from the rest of the surface, the other species of the genus having the dark-coloured

apical portion (when present) sculptured like the paler parts. Apart from the smaller

size, different colour, and the less dilated antennal joints, the smooth and glabrous femora

separate U. vermiculata from U. reticulata.

8. Uroplatopsis planicollis.

Elongate, opaque, sparsely clothed with erect hairs; reddish-ochraceous, the head in front, the neck, the eyes

and oral organs, a longitudinal stripe down the middle of the prothorax (sometimes indistinct), and the

suture of the elytra narrowly, to about the middle, piceous or fuscous. Head deeply longitudinally grooved

between the eyes, coarsely rugose in the middle in front, and with numerous coarse deep setiferous

punctures, the eyes convex and rather small; antennx black, joints 3-10 in both sexes broadly flattened

and each angularly dilated towards the apex, 3 much shorter and narrower than 4, the intermediate joints

the widest—the apical joint in the male about as long as 8-10 united, very little shorter in the female;

prothorax rather longer than broad, a little narrowed in front and (if viewed from the side) moderately

constricted behind, obsoletely margined at the sides, with a sinuous, smooth, shining, raised space on each

side extending from the base to the apex (the true lateral margin placed almost beneath this, and scarcely

visible from above), the broad space enclosed flat and very rugosely (but shallowly) punctured, a narrow

space within the lateral margin similarly punctured, the hind angles prominent, the basal margin rather

broad and much raised; elytra long, rounded at the shoulders, the sides almost straight from a little below

the base to beyond the middle, very deeply punctate-striate throughout, the third, fifth, seventh, and ninth

interstices narrowly costate nearly to the apex, and very closely and deeply transversely notched on each

side, the second, fourth, sixth, and eighth each with a double row of closely-packed granules, the apices

each with a short tooth within the angle ; beneath varying in colour from piceous to brownish-testaceous,

the sides of the metasternum coarsely punctured; legs moderately slender, piceous, the basal half or

the middle of the femora more or less testaceous, the femora and tibis somewhat thickly clothed with long

hairs.

Length 7-84 millim.; breadth 17-2 millim. (¢ 9.)

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion),

Numerous examples. From U, mimica this species may be at once distinguished by

the very broadly flattened and rugose disc of the thorax, the more slender and more

hairy legs, and the second, fourth, sixth, and eighth elytral interstices in the form of a

double row of very closely packed granules, the other interstices being narrowly costate

and closely and transversely notched on each side nearly to the apex. ‘The antenne

are similarly formed, but not quite so broadly serrate.

4. Uroplatopsis reticulata. (Tab. III. fig.11, 2.)

Elongate, subopaque, sparsely clothed with erect hairs; black, the head between and behind the eyes, the sides

of the prothorax broadly, and the sides of the elytra from the shoulder to about the middle (but rapidly

becoming more narrowly so) flavoug, and slightly shining. Head shallowly grooved between the eyes,

coarsely rugose in front, and with numerous coarse deep setiferous punctures, the eyes convex and rather

small; antenne black, joints 3-10 in both sexes broadly flattened, and each angularly dilated towards the

apex, 3 much shorter and narrower than 4, the intermediate joints the widest—the apical joint in the male

about as long as 8-10 united, scarcely shorter in the female; prothorax rather longer than broad, a little

narrowed in front and (if viewed from the side) feebly constricted behind, obsoletely margined at the sides,

with a sinuous, smooth, shining, raised space on each side extending from the base to the apex (the true

lateral margin placed almost beneath this, and scarcely visible from above), the broad space enclosed

flattened and very coarsely and deeply rugose and at the sides irregularly depressed, the hind angles

rather prominent, the basal margin narrow and moderately raised ; elytra long, rounded at the shoulders,

the sides almost straight from a little below the base to beyond the middle, very deeply punctate-striate

throughout, the fifth, seventh, and ninth interstices narrowly costate for the greater part of their length

and transversely notched on each side, the dark-coloured portion of the others with crowded and irre-

gularly packed granular points, the apices obtuse ; beneath piceous, the sides of the metasternum coarsely

punctured ; legs moderately slender, brownish-piceous, the anterior femora at the base and apex, and

the intermediate and posterior pairs at the apex, testaceous, the femora and tibiz sparsely clothed with

long hairs.

Length 6-74 millim.; breadth 13~13 millim. (¢ @.)

flab. Panama, Bugaba (Champion).

Two examples. JU. reticulata is closely allied to U. planicollis; it differs, however,

in the shallowly and indistinctly canaliculate head, the more coarsely rugose thorax,

the basal margin of which is narrower and less raised, and in the third elytral interstice

not being costate, as well as in colour. The dark-coloured portion of the elytra (instead

of having a closely-packed double row of granules on each interstice) is accompanied

by a difference of sculpture, the interstices having on this part more irregularly-packed

fine granular points. |

5. Uroplatopsis mimica, (Tab. III. fig. 12, ¢.)

Elongate, subopaque, clothed with scattered erect hairs; black, the head in great part, a broad stripe on each

side of the disc of the prothorax extending from the base to the apex (leaving a rather broad longitudinal

median stripe, and the sides, narrowly, of the ground-colour), and rather more than the basal half of the elytra

(except the suture.and epipleure) dull reddish-yellow. Head with a long and very deep groove between the

eyes and numerous very coarse and deep setiferous punctures, the narrow space on each side behind the eyes

and the middle of the front coarsely rugose ; eyes convex, moderately large ; antenne black, joint 3 short

and not half the width or length of 4, joints 4-10 in both sexes very broadly flattened and each angularly

dilated towards the apex, 4-7 increasing and 8-10 decreasing in width, 7 and 8 the widest—the apical

joint in the male nearly as long as joints 8-10 united, slightly shorter in the female; prothorax longer

than broad, a little narrowed in front, and feebly constricted behind, the sides margined at the base and

apex, the basal margin thick and raised, the hind angles prominent but not acute, the disc broadly and

longitudinally depressed from the base to the apex and with a very irregular deep oblong depression on

each side, the surface very uneven and coarsely, irregularly, and closely punctured, the punctures on the

depressed portion of the middle of the disc running into deep transverse or sinuous ruge; elytra long,

rounded at the shoulders, the sides almost straight from a little below the base to beyond the middle, very

deeply punctate-striate throughout, the interstices narrow and very closely and deeply transversely notched

on each side from the base to the apex, the third, fifth, seventh, and ninth narrowly costate for the greater

part of their length, the apices obtuse; beneath piceous-black, the sides of the metasternum coarsely

punctured ; legs rather stout, piceous, the femora towards the base and the coxe more or less testaccous,

the femora almost smooth, but with a few widely scattered hairs, the tibiee clothed within and without

with rather long hairs.

Length 8-9 millim.; breadth 23-23 millim. (¢ 2.)

Hab. Panama, Bugaba 1000 feet (Champion).

Four examples. This species bears a most remarkable resemblance to Uroplata

dimidiata, a species of Hispide inhabiting the same locality (cf. Biol. Centr. Am.,

Col. vi. pt. 2, p. 103, t. iv. fig. 13), the colour, structure of the antenne, elytral sculp-

ture, &c. being reproduced in a very similar manner. The longitudinally grooved and

irregularly wrinkled thorax and other particulars described above separate U. mimica

from the allied species described here.

** Elytra with an opaque lateral patch on each side about the middle.

6. Uroplatopsis simulans. (Tab. III. fig. 13, ¢.)

Elongate, narrow, subparallel, thickly clothed with erect hairs, the head and prothorax shining, the former

piceous, obscurely reddish between the eyes and in front, the latter testaceous, with a broad longitudinal

piceous stripe on the middle of the disc extending from the base to the apex; the elytra subopaque,

flavous, with a perfectly opaque fulvous lateral patch (small in the female, large and oblong in the male)

setiferous impressions between and behind the eyes, coarsely punctured in front, the eyes convex and

moderately large; antenne black, joints 3-10 very broadly flattened and each angularly dilated towards

the apex, 6-10 very sharply so, 3 the length of but much narrower than 4, 11 nearly as long as 7-10 in both

sexes ; prothorax longer than broad, a little narrowed in front, and feebly constricted behind, the sides

completely immarginate, the hind angles very prominent, the disc deeply canaliculate in the centre ante-

teriorly and with a very deep <-shaped impression on each side about the middle, the basal margin much

raised and preceded by a deep groove extending completely across, the sides and base rather coarsely and

irregularly punctured, the disc smooth; elytra very long, subparallel nearly to the apex, the disc flattened,

base to the apex, the fifth and seventh towards the base and the ninth towards the apex broader and

costate, the apices obtuse ; beneath entirely piceous ; legs rather long, piceous-brown, the femora towards

the base and the coxe more or less ferruginous, the femora and tibie sparsely and rather deeply (the

towards the apex and a little thickened there, the basal portion flattened and opaque within ; intermediate

and’ posterior femora deeply grooved along their inner side.

Hab. Panama, Volcan de Chiriqui 3000 feet (Champion).

Two examples. This and the following species differ from the allied Central-

American forms, U. excavata excepted, in the very peculiar sculpture of the thorax.

7. Uroplatopsis dilaticornis.

Closely resembling U. simulans :—The head similarly punctured between and behind the eyes, but with the

vertex convexly raised and smooth in the middle; the prothorax with the longitudinal stripe on the

middle of the disc narrowing and almost obliterated in front, the sides coarsely and rather closely punc-

tured ; the elytra with a small perfectly opaque fulvous lateral patch about the centre, the suture broadly

fusco-piceous, the fusco-piceous colour rapidly extending outwards from about the middle and towards

the apex reaching the lateral margin; the rest as in U. simulans.

Length 63 millim.; breadth 1} millim. (@.)

Hab. Panama, Bugaba (Champion).

One female example. This insect, at first sight, would appear to be only a colour-

variety of U. simulans; but the sculpture of the head is so different that it cannot be

treated as such. The apical joint of the antenne is unfortunately broken off.

-UROPLATOPSIS. 59

8. Uroplatopsis excavata. (Tab. III. fig. 14, 2.)

Elongate, narrow, subparallel, thickly clothed with erect hairs ; the head and prothorax shining, the head piceous-

brown, testaceous between the eyes, the prothorax testaceous, with a broad or mcderately broad longitudinal

piceous stripe on the middle of the disc extending from the base to the apex; the elytra dull, flavo-testaceous,

with a small (in the female) perfectly opaque fulvous lateral patch about the centre, the apical portion from

a little below the middle fusco-piceous, this colour extending along the suture and widening out a little

towards the base. Head with scattered very coarse setiferous punctures, sparsely and finely punctured in

front, shallowly canaliculate between the eyes, the latter convex and moderately large; antenne black, the

apical two-thirds of the last joint flavous, joints 3-10 very broadly flattened, and each angularly dilated

towards the apex, 6-10 very sharply so, 3 the length of but narrower than 4, 11( 2) about as long as 7-10

united ; prothorax longer than broad, a little narrowed in front, and feebly constricted behind, the. sides

completely immarginate, the hind angles prominent, the disc deeply canaliculate in the centre anteriorly and

with a very deep <-shaped impression on each side about the middle, the basal margin much raised and

preceded by a deep groove extending completely across, the surface with a few widely scattered fine

punctures, the disc smooth ; elytra very long, subparallel nearly to the apex, the disc flattened, the sides

towards the base almost vertical from the sixth row of impressions, the surface with regular rows of deep

foveate rounded impressions which extend to the apex, the interstices quite narrow and convex, each with

a row of closely placed very fine setiferous punctures extending from the base to the apex, the fifth and

seventh towards the base and the ninth towards the apex broader and costate, the apices obtuse ; beneath

entirely piceous ; legs rather long, piceous-brown, the femora and coxe piceo-testaceous, the femora and

tibia sparsely and rather deeply punctured and somewhat thickly clothed on all sides with very long

hairs.

Length 63 millim.; breadth 14 millim. (@.)

Hab. Panama, Bugaba (Champion).

One female example. This species closely resembles U. simulans; it differs thus :—

The apical joint of the antennz is in great part flavous; the head is smoother and

more sparsely punctured, the coarse deep punctures on the vertex being distant from

one another and not confluent; the prothorax is almost smooth at the sides; and the

elytra have the foveate impressions coarser, more rounded, and less numerous (owing

to their more rounded shape and larger size), aud the fusco-piceous apical patch very

much larger. From U. dilaticornis the smoother sides of the thorax and the larger and

less numerous foveate impressions of the elytral series sufficiently distinguish it; the

former, moreover, has the apical patch gradually (and not abruptly) narrowing anteriorly

and broadly extending along the suture to the base. |

9. Uroplatopsis appendiculata, (Tab. III. fig. 15, 3.)

Very elongate, narrow, subparallel, shining, sparsely clothed with long erect hairs, testaceous ; the prothorax

with a broad longitudinal piceous stripe on the middle of the disc extending from the base to the apex;

the elytra flavous, with (in the male) a large, oblong, perfectly opaque, fulvous lateral patch about the

middle, and the suture to some little distance below the base indeterminately and rather broadly fuscous.

Head shallowly canaliculate between the eyes, and with scattered setiferous punctures at the sides and

base, for the rest smooth, the eyes moderately large ; antenne ( ¢) long and stout, black, the apical joint

testaceous, joints 2 and 3 about equal in length, each slightly shorter than 4, 3-10 moderately widened

and each angularly dilated towards the apex, 7 and 8 the widest, 11 exceedingly elongate, equal in

length to 6-10 united, and much curved; prothorax considerably longer than broad, the sides completely

immarginate, feebly rounded, a little narrowed in front, and moderately constricted behind, the hind

angles very prominent, the disc with a small shallow fovea on each side before, and a very deep oblique

groove on each side behind the middle, the basal margin thick and much raised, and preceded by a deep

I1l2

groove extending completely across, the space between the two grooves raised and convex, the surface

quite smooth ; elytra very elongate and narrow, as wide just before the apex as at the base, flattened on

_ the disc, the sides compressed from a little distance below the base to about one fourth from the apex,

and towards the base almost vertical from the sixth row of impressions, the surface with regular rows of

deep foveate impressions, the impressions becoming finer at the apex and there placed in rather deep

strie, the interstices narrow and rather convex, strongly so at the apex, the fifth costate from a little

below the base to about the middle, the seventh costate at the extreme base, the first, third, fifth, seventh,

and ninth each with a row of rather closely placed fine setiferous punctures extending from the base to the

apex, the humeral callus smooth, the apices obtuse; beneath almost smooth, in great part piceous, the head,

prothorax, and coxee more or less testaceous ; legs moderately long, piceous-brown, the basal half of the

femora pallid testaceous and almost transparent, the anterior tibie finely and roughly punctured towards

the apex, the tibie and tarsi clothed with very long hairs, the femora glabrous.

¢. Anterior tibiz triangularly widened on the inner side near the base ; anterior femora concave within at

the apex; intermediate tibiee very abruptly bent inwards and thickened from about the middle, the basal

half flattened and opaque within ; intermediate femora clavate towards the apex, the clavate portion

deeply concave beneath ; posterior femora on their inner side dilated at about the middle into a long

and very broad pouch, the pouch deeply concave within, the apical portion also concave beneath.

Length 64 millim.; breadth 13 millim. (¢.)

Hab. Panama, Bugaba (Champion).

One male example only. This remarkable insect will be readily identified from our

figure. The male exhibits extraordinary sexual characters.

EPICYDES.

Last joint of the maxillary palpi very long, elongate-triangular, its outer side longer than the apical side; last

joint of the labial palpi large and broadly widened outwardly, its apical side deeply concave-emarginate ;

ligula prominent, deeply emarginate in the middle, and broadly rounded on each side in front; mentum

large, fully as long as broad at the base, much dilated on each side in front; outer lobe of the

maxillz moderately broad; mandibles simply unidentate at the apex ; antenne very long in both sexes,

joint 3 small and very short, in the male only a little longer than, and in the female about twice as long

as, 2,4 three or four (in the male) times as long as 3, 4-10 all very elongate and each very slightly

widened towards their inner apical angle, 11 exceedingly long in both sexes; eyes exceedingly large,

occupying the whole of the side of the head behind the orbits, above and beneath approximate in the

male, narrowly separated in the female; head very abruptly constricted behind the eyes into a distinct

neck ; anterior cox moderately exserted, the prosternum raised between them to the level of the coxe,

and convex in the middle behind; metasternal episterna almost flat, without distinct groove ; tibial spurs

short but distinct.

This genus is proposed for two new species, both from Mexico or Guatemala.

Epicydes approaches Disema, Makl., a genus containing numerous representatives in

Tropical South America; but differs from it in the exceedingly short third joint

of the antenne, broad and emarginate apical joint of the labial palpi, &c. As in

Disema, the eyes are very largely developed, and occupy the greater portion of

the head; in the present genus, moreover, the antenne are not strongly serrate (as in

Disema), joints 4-10 being only a little widened towards their apex. The described

species of Disema are stated to have an opaque patch on each side of the elytra, a

character not shared by either of the two referred to Epicydes; certain undescribed

forms, apparently referable to Disema, do not, however, possess this. |

Nemostira, Fairm., from Madagascar, also resembles Epicydes in some of its characters.

EPICYDES.—SPHRAGIDOPHORUS. 61

1. Epicydes oculatus. (Tab. III. figg.16,¢ ; 16a, labium ; 16 4, maxilla and

maxillary palpus; 16 ¢, mandible.)

Very elongate, opaque, black or brownish-black, the elytra sometimes piceous-brown. Head with a few

setiferous punctures behind and at the sides, for the rest smooth; antenne very long, fusco-ferruginous

or ferruginous—the apical joint very elongate in both sexes, in the male longer than, in the female about

equalling, joints 8-10 united ; prothorax about as long as broad, convex, the sides finely margined towards

the base, moderately rounded anteriorly, and strongly constricted behind, the hind angles sharp and very

prominent, the basal margin much raised, the disc obsoletely canaliculate in front and sometimes a little

depressed in the middle behind, the surface finely, rather deeply, and somewhat thickly punctured ; elytra

with shallow intrahumeral depression, very long, widest beyond the middle, finely and deeply punctate-

striate throughout, the punctures approximate, the interstices rather convex, flatter towards the base, the

first with about five (varying in position—sometimes two at the apex and two or three at the base, and

sometimes with only one or two near the apex), the third with from six to ten (scattered between the

base and apex), the fifth and seventh with from three to six (scattered between the base and apex and

sometimes obsolete), and the ninth with four or five (near the apex), fine setiferous punctures, the apices

obtuse; beneath varying in colour from piceous to reddish-brown, the sides of the metasternum thickly

punctured; legs long, varying in colour from piceous to testaceous, the femora smooth and glabrous.

Length 113-142 millim.; breadth (at the shoulders) 3-4 millim. (¢ @.)

Hab. Mexico (coll. F. Bates), Playa Vicente, Cordova, Juquila (Sailé), Cerro de

Plumas (Hége); Guatemata, Las Mercedes (Champion).

Seven examples. The widely scattered setiferous impressions on the alternate elytral

interstices vary in number and position, and many of them are sometimes obsolete, the

first and third interstices, however, invariably have two or three at the apex. The

single specimen from the Guatemalan Pacific slope agrees well with the others from

the Atlantic slope of Mexico. . oculatus is separated in the Sallé collection into no

less than four species.

2. Epicydes vicinus.

Closely resembling H. oculatus, and differing as follows :—Slightly shining ; the elytral striee deeper and cren-

ately punctured, the interstices more convex, the first, third, fifth, seventh, and ninth each with one or

two irregular rows of rather closely placed setiferous punctures extending from the base to the apex; the

legs varying in colour from fusco-castaneous to testaceous with the knees and tarsi piceous; the rest as

in £. oculatus.

Length 134-164 millim. ; breadth (at the shoulders) 33-43 millim. (¢ 9.)

Hab. Guatemata, San Juan and Senahu in Vera Paz (Champion), Coban (Conradt) ;

NicaraGua, Chontales (Belt).

Four examples only, all from the Atlantic slope. The very numerous setiferous

impressions on the alternate elytral interstices and the more convex interstices and

deeper striz readily distinguish E. vicinus from E. oculatus. The upper surface is also

less opaque.

SPHRAGIDOPHORUS.

Last joint of maxillary palpi subsecuriform, that of the labial palpi very broad and subsecuriform ; ligula very

prominent, extending laterally as far as the sides of the mentum; mentum trapezoidal; outer lobe of

62 HETEROMERA.

the maxille rather narrow; mandibles bifid at the apex; eyes convex, rather small; head-(larger in

S. singularis) extended on each side behind the eyes, abruptly narrowed into a neck behind; antenne

long and stout, joints 3-10 differing very little in length or breadth (7 and 8:the longest) and but little

widened outwardly, 11 very elongate, especially in the male; prothorax cylindrical ; elytra, at least in

the male, with an oblong perfectly opaque patch on each side at or beyond tbe middle; anterior coxe

moderately exserted, the prosternum raised between them to the level of the coxe ; metasternal episterna

quite flat (S. cyanipennis), or (S. singularis) depressed within the inner edge anteriorly ; anterior femora

and tibie in the male more or less abnormal and sulcate, the tibiee inwardly or outwardly curved ;

tibial spurs short or indistinct.

This genus is proposed to include Statira cyanipennis, Makl. (from Mexico, but now

known to extend southwards to Chiriqui), and an allied species from the State of

Panama; a third, also from the State of Panama, of which we have only a single

mutilated female example, is also provisionally referred to it; and S. thoracica, Makl.,

from Brazil, and S. sculpta, Kirsch, from Peru, may possibly have to be included

in it. The very pronounced sexual characters in the anterior legs in the male,

the very broad apical joint of the labial palpi, and the opaque patch on each side

of the elytra in one or both sexes, are characters foreign to the very large number

of species (about 150) of Statira known to me. The male of S. cyanipennis (and

apparently of S. violaceus also) possesses a very complicated cedeagal structure, the

genus differing greatly from Statira in this respect. ‘The above-mentioned characters

are chiefly taken from S. cyanipennis.

* Eyes rather small ; size small.

a. Head and prothorax red, the elytra violaceous.

1. Sphragidophorus cyanipennis. (Tab. III. figg. 17, 3; 17a, labium;

Hab. Mexico ', Cordova (Sallé) ; GuatumaLa, Panzos (Champion) ; Panama, Bugaba,

Volcan de Chiriqui (Champion).

This is a species of small size, with the head and thorax red and the elytra cyaneous

or violaceous and subopaque. ‘The antenne are black (the basal joint sometimes red),

long and stout; the apical joint in the male is longer, in the female shorter than, the

three preceding joints united. The head and thorax have widely scattered coarse

punctures, between which on the thorax are a few finer impressions; the thorax is

immarginate at the sides; the eyes are quite small and distant from the base of the

head ; the elytra are rather coarsely punctate-striate, and have the interstices almost

flat at the base and rather convex towards the apex, the first, third, and fifth from the

T Maklin subsequently (ify, Finsk. Soc. xxi. p. 116) described another species of Statira, from Colombia,

under the name of cyanipennis: this might be renamed colombica. |

SPHRAGIDOPHORUS. 63

base to the apex with scattered setiferous impressions; the legs vary in colour from

black to testaceous, and the femora and tibie are furnished with a few long hairs; and

the under surface also varies in colour, though the venter is always more or less black.

The male exhibits the following characters :—The anterior and intermediate femora

are deeply sulcate within from the base nearly to the apex; the anterior tibie are a

little curved inwardly, and broadly concave within, the concavity opaque; and the elytra

have each at the side a large oblong perfectly opaque black or ashy median patch, upon

which faint. lines representing the position of the strize are visible. The opaque

patch at the side of the elytra is also exhibited in the male of the following species

(and in the female, the only sex known, of S. singularis) and in other Lagriide

inhabiting Tropical South America; it is absent in the female of S. cyanipennis. The

cedeagus of the male is developed in an extraordinary manner, and when extruded

a very long and slender clasping-piece, hooked at the end, is to be seen on either

side of the central sheath.

The description of Maklin, though lengthy and based upon male examples, is very

incomplete, the important structure of the anterior and intermediate legs &c. being

overlooked altogether.

Five examples are now before me, including both sexes.

b. Upper surface unicolorous, violaceous.

2. Sphragidophorus violaceus. (Tab. III. fig. 18, 3.)

Rather short, subopaque, violaceous. Head with a few scattered coarse deep setiferous punctures, the eyes

small and distant from the base; antennez (¢) very long and stout, black, the apical joint not quite so

long as joints 8-10 united; prothorax about as long as broad, cylindrical, the sides immarginate, mode-

rately rounded in front, and constricted behind, the hind angles acute, the disc transversely impressed in

the middle behind, the basal margin moderately raised, the surface with a few widely scattered coarse

deep punctures between which are some finer ones; elytra (in the male) with a large oblong perfectly

opaque brownish-black lateral patch about the middle (upon which faint lines indicating the position of

the strie are visible), comparatively short, widest about the middle, finely punctate-striate, the punctures

becoming much coarser towards the sides and obliterated before the apex, the interstices flat, rather convex

towards the apex, the first, third, and fifth each with a few widely scattered fine setiferous punctures, the

apices obtuse ; beneath violaceous ; legs dark violaceous, the femora and tibize each with a few long scat-

tered hairs.

¢. Anterior femora a little curved, very deeply sulcate within from the base to about the middle, dilated on

the lower side at the extreme base, and with a small deep ovate depression on their upper face at the

extreme apex ; anterior tibie slightly curved outwardly, and very deeply sulcate on their upper face from

the base to the apex.

Length 5 millim.; breadth 13 millim. (¢.)

Hab. Panama, Bugaba 1000 feet (Champion).

One male example only. This very interesting little species is allied to, though

much smaller than, the preceding, and, like it, possesses very peculiar male characters.

It also differs thus :—The upper surface is uniformly violaceous ; the antenne ( ¢ ) have

64 HETEROMERA.

a shorter apical joint; and the elytra are relatively shorter and have the strie (especially

on the basal half of the disc) more finely punctured.

The extraordinary sexual characters exhibited in the male are, so far as I am aware,

different from those of any known species of Coleoptera:—The anterior tibie are

outwardly curved (the reverse to the usual way), and the groove, instead of being

upon the outer or inner edge (as usual, when present), is upon the upper face.

** Eyes large; size larger; upper surface unicolorous, violaceous-black.

9 pp

3. Sphragidophorus singularis. .

Very elongate, rather convex, opaque, black, with an indistinct violaceous tinge, the elytra of a browner tint

towards the base. Head with a few setiferous punctures at the base and sides, for the rest smooth ; eyes

convex, moderately large, rather distant from the base of the head, the latter a little extended on each side

behind them; antenne long, rather stout, black (the apical joint broken off); prothorax cylindrical, much

longer than broad, the sides completely immarginate, narrowing somewhat obliquely in front, and mode-

rately constricted behind, the hind angles acute and very prominent, the basal margin much raised, the

surface smooth, except for a deep puncture on each side behind, and an indistinct one on each side before,

the middle of the disc ; elytra with shallow intrahumeral depression, very long, subparallel in their basal

half, each with an oblong very opaque lateral depression (almost destitute of sculpture) some distance

beyond the middle, finely punctate-striate, the punctures becoming a little coarser towards the sides and

finer towards the apex, the striae not extending to the apex, the interstices flat, the first with five or six

(very irregularly scattered between the base and apex, those towards the apex the deepest), and the third

with two (near the apex), setiferous punctures, the apices obtuse ; beneath black; legs smooth, black,

very long; the posterior femora somewhat flattened, their inner face grooved along the lower edge from

about the middle to the apex.

Length 11 millim.; breadth 2? millim. ( 9.)

Hab. Paxama, Volcan de Chiriqui (Champion).

A single female example. This insect has a different facies from any species here

referred to Statira. The elytra have an oblong very opaque depression (almost destitute

of sculpture) at the sides, as in the opposite sex of S. cyanipennis and S. violaceus and

certain other South-American forms; the male doubtless has this depression much

larger. The posterior femora are grooved and somewhat flattened. S. simgularis may

be further distinguished by its opaque violaceous-black colour, very elongate shape,

cylindrical and immarginate thorax, the hind angles of which are acute and very pro-

minent, and other details noticed above.

MENISCOPHORUS.

Last joint of the maxillary palpi subtriangular, its outer side a little longer than the apical side ; last joint of

the labial palpi broad and crescentiform, its apical side very deeply concave-emarginate ; ligula prominent,

emarginate in the middle and rounded on each side in front; mentum trapezoidal, transverse ; outer

lobe of the maxille broad; mandibles bifid at the apex; antenne stout, with joints 3-10 about equal in

length and breadth, and each moderately widened (but not serrate) towards their apex, 11 about as long

as 9 and 10 united in the female, and only a little longer in the male; eyes convex, moderately large,

somewhat widely separated; head obliquely narrowed behind the eyes and then constricted into a neck ;

MENISCOPHORUS. 65

elytra with an oblong impunctate depression on each side, the depression velvety within ; anterior cox

moderately exserted, the prosternum raised between them; metasternal episterna almost flat, without

distinct groove; tibial spurs scarcely visible.

Two species, one from the State of Panama and one from the Amazons *, agree in

the above particulars, and they are accordingly separated into a distinct genus. Both

have a depressed opaque impunctate velvety patch on each side of the elytra towards

the apex, the elytra themselves being very coarsely crenate-striate. The very broad

apical joint of the labial palpi is still more deeply emarginate than in Epicydes or

in any species of Colparthrum. The two species referred to it bear a superficial

resemblance to various Hispide and Lycide. The male of MU. costatus has the

anterior femora toothed and the anterior tibiae sinuous, that of MM. amazonicus,

however, does not exhibit any marked peculiarity in this respect.

1. Meniscophorus costatus. (Tab. III. figg. 19, ¢; 19a, labium; 19 4,

maxilla and maxillary palpus; 19 ¢, mandible.)

Moderately elongate, black or brownish-black, opaque, the head (except the eyes and at the sides behind them),

the disc of the prothorax very broadly from the base to the apex, and the sides of the elytra broadly from

the base to beyond the middle (but gradually becoming more narrowly so) testaceous. Head impressed

in the middle of the intraocular space, very minutely and sparsely punctured (if viewed under a very strong

lens), the dark-coloured space behind the eyes coarsely and closely so, and with a deep setiferous impres-

sion on each side between the eyes in front, the latter moderately large ; antennz densely clothed with short —

hairs, rather long, very stout, joints 3-10 each widened towards their apex, 3 and 4 about equal in length,

black or piceous, the apical joint fusco-ferruginous, the latter only as long as joints 9 and 10 united in the

male and scarcely shorter in the female; prothorax cylindrical, longer than broad, the sides and apex

completely immarginate, the former feebly rounded anteriorly and strongly and rather abruptly con-

stricted behind, the basal margin broadly raised and at the sides deeply grooved within, the disc with a

very deep transverse impression on each side before the middle and a shallow oblique one on each side

behind, the latter almost connected with a shallow transverse impression before the base and thickly

and moderately finely punctured, the dark-coloured portion of the sides more coarsely and closely so ;

elytra with indistinct intrahumeral depression, moderately long, subparallel in their basal half, each

with a depressed oblong perfectly opaque velvety lateral patch (larger and longer in the male

than in the female) towards the apex, coarsely and deeply crenate-striate, the punctures becoming finer

beyond the middle, the interstices strongly convex and costate from the base to the apex and without

* Meniscophorus amazonicus.

Flavous, opaque, the prothorax with the sides broadly, and the elytra with a large and broad quadrangular

patch extending to beyond the basal third, the lateral margins very narrowly for the same distance, and

rather more than the apical third, brownish-black, the elytra with a large depressed opaque brownish

patch on each side towards the apex; antennw with the apical joint flavous: prothorax considerably

longer than broad, the disc with a foveate impression on each side about the middle and an oblique one

(deepest in front) on each side towards the base, the surface very closely, coarsely, and uniformly punctured ;

elytra coarsely and deeply crenate-striate, the interstices convex throughout ; beneath almost smooth, piceo-

testaceous, the sides stained with piceous; legs brownish-piceous, the basal half of the femora testaceous,

the four hinder tarsi fusco-ferruginous.

Four examples, two of each sex. This insect has somewhat the facies. of certain

species of Uroplatopsis, owing to the peculiar sculpture and colour of the elytra

(resembling that of many Lycide and Hispide); but differs from them in the non-

dilated intermediate joints of the antenne, differently-formed labial palpi, toothed

anterior femora in the male, &c.

COLPARTHRUM.

Colparthrum, Kirsch, Berl. ent. Zeitschr. 1866, p. 204.

Kirsch founded this genus upon a single species, C. gerstdckeri, Kirsch, from.

Colombia, and gave as its chief diagnostics—(1) mandibles at the apex with three

strong teeth of equal length, (2) last joint of the labial palpi deeply emarginate in

front, and almost crescentic in shape, (3) tibie with distinct spurs; and, among other

characters of less importance, (4) parapleura (metasternal episterna) along the inner

suture with a furrow which in front is bent inwards in an almost rectangular manner

(instead of an impression occupying almost the entire surface and becoming smaller

behind, as in Statira), (5) eyes more convex than in Statira, (6) antenne with the

apical joint scarcely one and a half times the length of the tenth. ‘I'wo species from

Central America, Statira decorata, Makl., and a new one described here, agree exactly

in these particulars*; but they also have the femora more or less clavate, of which no

mention is made either by Kirsch or Maklin. In addition to these two species, three

others from Central America agree in these characters, with the exception of the last

joint of the labial palpi being simply triangular and not emarginate in front, and

in the last joint of the antenne being very elongate in the males of two of them.

These species must either be treated as congeneric-or separated into three genera ;

the former seems to be the proper course, and the following diagnosis will include

them all :—

Last joint of the maxillary palpi securiform ; last joint of the labial palpi very broad and triangular—its apex

concave-emarginate (very deeply so in C. decoratum, moderately so in C. foveiceps), or almost straight

(C. calcaratum, C. sulcicolle, C. vitticolle); outer lobe of the maxillee short and very broad (much broader

than in Statira); mentum extended on each side in front; ligula short and very broad, fan-shaped,

extending laterally beyond the anterior angles of the mentum; mandibles furnished at the apex with

three teeth (very long in C. sulcicolle) of equal length; eyes moderately large, convex, distant from the

base of the head, and with a deep transverse impression (rarely effaced), on either side of which is a

setiferous puncture, between them; head strongly and obliquely narrowed behind into a neck ; antennse

variable—the apical joint comparatively short in both sexes, scarcely equalling 9'and 10 united, or very

elongate in the male (C. foveiceps and C. vitticolle); prothorax strongly compressed and completely

immarginate at the sides, and with a groove behind extending completely across; elytra subparallel

towards the base, and with the sides converging from about the middle; anterior cox moderately

exserted, the prosternum raised between them to the level of the cox; metasternal episterna (para-

pleura) with a narrow deep groove along the inner edge, the groove turned abruptly outwards in front

and continued along the anterior margin ; tibie not grooved on their outer edge, and with one or two

spurs of variable size—in C. calcaratum and C. sulcicolle with one only (in C. decoratum and C. foveiceps

they are short but distinct, in C. vitticolle indistinct) ; femora more or less clavate towards the apex.

C. decoratum and C. calcaratum are obviously very closely allied, notwithstanding

the difference in the shape of the last joint of the labial palpi and in the presence of a

very long single spur to each of the tibie in C. calcaratum. The presence or absence

of spurs to the tibiz cannot be treated as of generic value, unless accompanied by other

differences of structure, and, moreover, they are often difficult to detect amongst the

short bristly hairs clothing the apices of the tibie. The deep groove along the inner

margin of the metasternal episterna is very sharply cut, and it is apparently a character

of generic value. The five Central-American species here referred to Colparthrum all

have a very deep transverse impression (rarely effaced) between the eyes. The femora

are moderately clavate in C. decoratum and C. foveiceps, strongly so in C. calearatum,

C. sulcicolle, and C. vitticolle.

Many specimens of both the type and the variety. The latter, no doubt, represents

a southern race of the same species; it is connected by intermediate forms. This

species is more or less reddish-brown or castaneous in colour and shining, and of

moderately elongate shape; the elytra each having a transverse flavo-testaceous band

or spot. (of variable size) before the middle, and another close to the apex, the spots

separated from the suture by a narrow line of the ground-colour, and each usually

preceded and followed by a curved or transverse black or piceous band—this is some-

times (especially in the variety) continued round the external edge of the anterior spot,

and is occasionally (as in several Guatemalan examples) more or less obliterated or

obsolete from both. The head has a broad, deep, transverse impression between the

eyes (in which are two setiferous impressions), and some setiferous impressions behind,

but for the rest smooth; the eyes are laterally prominent but not very large. The

antenne are rather long and the apical joint is hardly so long as joints 9 and 10

united in either sex. The thorax is quite smooth, very convex and cylindrical,

completely immarginate, and has a deep transverse groove behind, this groove

obliquely extended downwards at the sides and there becoming very deep. The elytra

have a prominent humeral callus, and rows of rather coarse deep punctures placed

upon shallow strie, the punctures somewhat distantly placed and becoming still coarser

towards the sides and base, and obsolete towards the apex, the sutural one only extend-

ing to the apex itself; the interstices are flat throughout, the alternate ones each with

an irregular row of fine scattered setiferous impressions extending from the base to the

apex, the sete very long and erect. The legs vary in colour from reddish-brown to

testaceous ; the femora are quite slender at the base and become gradually clavate

towards the middle (the posterior pair rather abruptly narrowed towards the base), and

are smooth and glabrous ; and the tibie are a little curved, their outer edge glabrous

and rounded, and have two very short spurs.

C. gerstdckeri, Kirsch, from Bogota, must be closely allied to this widely-distributed

species, though its author does not appear to have been aware of it; in the description

of the former, however, no mention is made of the presence of setiferous impressions

on the elytra, these being present on each of the alternate interstices in C. decoratum.

A male specimen from Coban is figured.

Head with a broad and deep transverse impression (on either side of which is a deep setiferous puncture)

between the eyes and a few setiferous punctures at the sides and behind, for the rest smooth, the eyes

moderately large; antenne testaceous or ferruginous, the two basal joints darker, long, moderately

slender—the apical joint in the male nearly as long as joints 8-10, in the female less than 9 and 10,

rounded anteriorly, and compressed and constricted behind, the hind angles prominent but not acute, the

disc transversely grooved behind (the groove on each side obliquely extended downwards and there

long, with regular rows of closely placed foveate impressions (which become coarser and deeper towards

the sides) to a little beyond the middle and thence for some distance rather deeply striate (still more

Six examples. This species is allied to C. decoratwm; it differs, however, in its

smaller size, dark unicolorous surface, longer and more slender antenne, the apical

joint much longer in the male (and not, as in the corresponding sex of C. decoratum,

short, as in the female), the elytra with still coarser and deeper impressions anteriorly,

and rather deeply striate beyond the middle (though smooth at the apex), and with

only a few setiferous impressions before the middle (these are continued to the apex

in C. decoratum). The posterior femora in both sexes, as in C. decoratum, are abruptly

widened from before the middle.

Very elongate, narrow, very shining, the head and prothorax of a brilliant eneous or golden-green colour, the

elytra metallic green. Head long, with a broad and deep transverse impression (on either side of which

is a setiferous puncture) between the eyes, a deep longitudinal groove in front, and a few widely scattered

setiferous punctures at the sides and base, for the rest smooth, a little rounded at the sides behind the

eyes; eyes convex, rather small, and distant from the base of the head; antenne very slender, moderately

long, ferruginous—the apical joint in the male not so long as joints 9 and 10 united, in the female only a

little longer than 10; prothorax cylindrical, very much longer than broad, the sides completely immargi-

nate, slightly rounded anteriorly, and compressed and moderately constricted behind, the hind angles

rather obtuse, the disc with a very deep transverse groove on each side about the middle and a shallower

one running completely across at the base (the latter on each side extending downwards and there

becoming very deep), the surface smooth; elytra with prominent shoulders, very long, widest about

the middle, shallowly transversely depressed below the base, with regular rows of closely-placed foveate

impressions to beyond the middle, the impressions then abruptly becoming finer and shallower and from

here almost to the apex inserted in deep striz (the striz, the first excepted, not quite reaching the apex,

and extending upwards along the suture to the transverse depression and very coarsely crenate-punctate

along this part), the interstices almost flat at the base, but becoming very convex beyond the middle,

the first excepted, do not extend so near to the apex, and feebly convex interstices.

Hab. Nicaracva, Chontales (Janson).

Seven examples of the type and one of the variety. The latter differs very consider-

ably from the others in the intensity of the elytral sculpture, but it doubtless repre-

sents no more than a local form of the same species. The central sheath of the

cedeagus of the male terminates in a broad sharply-angled triangular piece. C. swlei-

colle is allied to C. decoratum, C. calcaratum, &c., but differs from these in its relatively

narrower and more elongate shape, longer head, brilliant metallic green or golden-

green colour, &c. The elytral sculpture, as in C. vitticolle, somewhat resembles that

of certain species of Strongylium. The thorax is not only transversely grooved

towards the base, but has another transverse deep eroove on each side of the disc about

the middle.

A typical specimen from the. Volcan de Chiriqui is figured.

** Antenne with the apical joint very elongate in the male; upper surface flavo-

testaceous, the prothorax with a black stripe on each side, the elytra spotted.

Elongate, yellowish-testaceous, shining ; the prothorax with a long sinuous piceous stripe on each side; the

elytra with a common broad transverse band at the base (not extending to the humeral callus or lateral

margin), another about the middle (connected with the anterior one along the suture, extending to the

lateral margin, and angulate on its lower edge), and an ill-defined oblique patch (connected at the suture)

towards the apex, dark brown, the bands reddish within and enclosing a broad transverse yellowish one.

Head with a broad and deep transverse depression between the eyes and a few setiferous punctures at

the sides and behind, for the rest smooth, the eyes moderately large; antennee ( ¢ ) flavo-testaceous, long

and very slender—the apical joint rather longer than joints 8-10 united, the latter elongate ; prothorax

cylindrical, very much longer than broad, the sides completely immarginate, much rounded anteriorly, and

compressed and strongly constricted behind, the hind angles prominent but not acute, the disc with a deep

transverse groove behind, the surface quite smooth; elytra with prominent shoulders, widest about the

middle, with regular rows of closely-placed deep foveate impressions to a little beyond the middle and

thence for some distance deeply striate (with fine crenate punctures), the striew (the first excepted) not

continued to the apex, the interstices flat to about the middle and at the extreme apex, for the rest

convex, the third, fifth, and ninth each with two or three very fine setiferous punctures towards the apex,

the apices obtuse ; beneath and the legs yellowish-testaceous, the latter long; the femora clavate towards

the apex, quite slender at the base, and smooth and glabrous; the tibie and tarsi long and very slender,

COLPARTHRUM. Gi

One male example. This is one of the most elegant forms of Lagriide known to

me. C. vitticolle is allied to C. decoratum and C. calcaratum, but differs from both of

these in the peculiar sculpture of the elytra (suggestive of that of certain species of

Strongylium), and in the very slender antenne, the last joint of which is very long

in the male. The tibie are thickly clothed with long erect hairs within, but are

smooth and glabrous without. The last ventral segment in the male has on each side

a long curved lobe, the lobe shaped very much as in the same sex of Alethia azteca

(cf. Biol. Centr.-Am., Col. iv. pt. 1, p. 418, t. xix. fig. 8). The lighter-coloured portions

of the elytra are flavo-testaceous, like the head, thorax, and legs.

b. Tibie each with a single very long spur; elytra (and fifth ventral segment) sharply

mucronate at the apex, and spotted.

5. Colparthrum calcaratum. (Tab. III. fig. 23, 2.)

Elongate, rather narrow, shining, varying in colour from reddish-testaceous to castaneous or reddish-brown,

the sides of the prothorax often a little darker than the disc; the elytra each with a rather broad trans-

verse flavous band before the middle (not reaching the suture and usually widening outwardly and

extending to the lateral margin, but sometimes small and in the shape of a large spot), the flavous band

usually surrounded (except laterally) by a broad belt of a darker and more piceous-brown colour, the

lower margin of which is oblique, and the suture sometimes stained with piceous for some distance beyond

the middle. Head with a broad and deep transverse impression (on either side of which is a setiferous

puncture) between the eyes and a few setiferous punctures at the sides and behind, for the rest smooth,

the eyes convex but rather small; antennz moderately slender, more or less ferruginous—the apical joint

in the male about as long as, in the female shorter than, joints 9 and 10 united; prothorax cylindrical,

much longer than broad, the sides completely immarginate, much rounded anteriorly, and compressed and

strongly constricted behind, the hind angles prominent but not acute, the dise transversely grooved behind,

the surface smooth ; elytra with prominent shoulders, slightly transversely impressed below the base,

widest about the middle, with rows of coarse or moderately coarse punctures, which beyond the middle

become (abruptly) very much finer, and do not (the sutural row excepted) extend to the apex, the inter-

stices flat throughout, the first, third, fifth, seventh, and ninth each with numerous setiferous punctures

scattered between the base and apex (the sete very long and erect), the apices sharply mucronate ; beneath

varying in colour from testaceous to reddish-brown, very shining, the apical margin of the fifth ventral

segment in both sexes sharply mucronate in the middle; legs long, more or less testaceous, the femora

sometimes darker, the latter strongly clavate towards the apex and slender at the base, the tibise and

tarsi long and slender, the tibie and the apical halves of the femora clothed on all sides with long erect

hairs; the tibiee each with a single long sharp spur at the apex.

Hab. Nicaragua, Chontales (Janson, Belt); Costa Rica, Volcan de Irazu, Cache

(Rogers); Panama, Volcan de Chiriqui 3000 feet (Champion).

Numerous examples. This remarkable species, which in some of its characters

departs widely from any other member of the Lagriide yet described, is allied to

C. decoratum and C. vitticolle. It differs from both, however, in the tibiee being each

furnished with a single very long spur, and in each elytron and the fifth ventral segment

being sharply mucronate at the apex in both sexes. C. calcaratum is smaller than

C. decoratum (the elytra, as in that species, varying considerably in colour), and differs

also in the tibiee and femora being clothed on all sides with long erect hairs; from

12 HETEROMERA.

C. vitticolle the very differently sculptured elytra distinguish it at once. A well-marked

specimen from Cache is figured.

OTHRYADES.

Last joint of the maxillary palpi subsecuriform, that of the labial palpi broad and triangular; mandibles fur-

nished at the apex with three teeth of equal length; outer lobe of the maxille extremely broad and large,

the inner lobe narrow; ligula very broad, fan-shaped, and extending laterally beyond the anterior angles

of the mentum; mentum transverse, angularly extended on each side in front; eyes large, convex,

rather widely separated above and beneath ; head strongly and obliquely constricted behind into a neck,

without transverse impression between the eyes ; antenne long, exceedingly slender, joints 3-10 each a little

thickened at the apex, very elongate, 3 about twice the length of 2 (11 broken off); prothorax cylindrical,

completely immarginate and feebly compressed at the:sides ; elytra very long, parallel to about the middle

and thence to the apex converging ; anterior coxee moderately exserted, the prosternum very narrowly

raised between them; metasternal episterna with a narrow deep groove along the inner margin, the

groove turned abruptly outwards in front and continued along the anterior margin ; legs long and slender,

the femora not clavate, the tibie rounded on their outer edge and with indistinct spurs.

A single species only, from the State of Panama, is referred to this genus. O. fragili-

cornis, in the structure of the oral organs and some other particulars, closely approaches

certain species here referred to Colparthrum (C. sulcicolle &c.), but differs from these

in the non-clavate femora, large eyes, and exceedingly slender antenne. Othryades

should be placed near the Australian genus Xenostethus.

1. Othryades fragilicornis. (Tab. III. fig. 24,3; 24a, labium; 244, maxilla

and maxillary palpus; 24 c, mandible.)

Very elongate, convex, subparallel, shining, brownish-piceous or dark castaneous, the elytra «neous. Head

with a few very fine setiferous punctures at the sides and base, for the rest smooth, the eyes convex and

large, the space between them flat; antenne ferruginous, long, exceedingly slender and with very elon-

gate joints in both sexes (the apical joint broken off); prothorax cylindrical, longer than broad (sometimes

a little shorter), the sides completely immarginate, a little rounded anteriorly, and moderately constricted

behind, the hind angles prominent but rather obtuse, the apical margin sharply, and the basal margin

moderately, raised, the disc shallowly transversely depressed behind, the surface smooth ; elytra with very

shallow intrahumeral depression, rather coarsely punctate-striate to about the middle and beyond this very

much more finely and shallowly so, the punctures not very closely placed, the stria (including the first)

not extending to the apex, the interstices almost flat, the third with about six and the fifth with about

three (scattered between the base and apex), the seventh with one (at the shoulder), and the ninth with

three or four (near the apex), fine setiferous punctures, the apices mucronate ; beneath sneo-piceous, very

shining, smooth ; legs long and slender, ferruginous, the femora usually more or less piceous, the latter

smooth and glabrous.

Length 97-12 millim.; breadth 2-3 millim. (¢ 92.)

Hab. Panama, Volcan de Chiriqui 3000 feet (Champion).

Eight examples. This species may be distinguished from all the allied New-World

forms by its remarkably slender and fragile antenne ; these organs are broken in all the

specimens before me, not one possessing an apical joint. O. fragilicornis somewhat

resembles Statira viridicollis in shape, but has the thorax more cylindrical, completely

immarginate at the sides, and smooth, and the elytra mucronate at the apex, as well as

having very differently formed palpi, antenne, &c.

RHOSACES,—STILPNONOTUS. 73

RHOSACES.

Last joint of the maxillary palpi broad and securiform, that of the labial palpi ovate; mentum transverse ;

mandibles bifid at the apex, the lower tooth the longest and very sharp; eyes rather small, convex, widely

separated above and beneath, and placed very far from the base of the head, the latter obliquely narrowed

behind them into a long neck; epistoma very short and separated from the front by a deeply impressed

groove ; antenne short, extending to a little distance beyond the base of the prothorax, similar in both

sexes, joints 1-3 moderately slender, 4-11 much stouter and becoming still stouter outwardly, 3 one anda

half times the length of 2, 4~7 each longer than 3, 8 and 9 about as long as broad, 10 transverse, 11 short,

ovate, and not longer than 8; prothorax cylindrical, completely immarginate and compressed at the sides,

and with a groove behind extending completely across; elytra with prominent humeri, short and convex,

nearly twice as broad as the prothorax at the base, gradually widening to about the middie and thence

rounded and converging to the apex; anterior coxe moderately exserted and not ‘contiguous, the pro-

sternum raised between them ; metasternum short and convex, not longitudinally grooved in the middle,

the episterna without groove; intercoxal process broad, rounded in front, the posterior coxee widely

separated ; ventral segments with one or two fine setiferous punctures on each side; legs short. and

slender, the femora clavate outwardly ; first joint of the posterior tarsi very long, longer than the other

three joints united ; tibial spurs indistinct.

The single species from the State of Panama referred to this genus somewhat resembles

an Anthicus. Rhosaces, apart from its different facies, may be at once separated from

Statira and the allied forms by the intercoxal process being broadly rounded in front,

the posterior coxe widely separated, the epistoma very short, and the antenne widened

outwardly and with very short apical joint. An undescribed genus, of which one or

two species from Peru are contained in Mr. F. Bates’s collection, is intermediate in some

respects between Ehosaces and certain small Casnoniiform Statire inhabiting Tropical

South America; the present genus, however, is abundantly distinct from all these.

1. Rhosaces clavipes. (Tab. III. fig. 25.)

Varying in colour from black to castaneous, the elytra often of a more castaneous tint than the head and pro-

thorax (in one dark-coloured example with the apical two-thirds reddish-castaneous), shining. Head

with a few very fine setiferous punctures at the sides and behind the eyes, for the rest smooth ; antennz

black, the basal joints, and sometimes the apical one, reddish; prothorax about or not quite so long as

broad, the sides rounded in front and constricted behind, the hind angles moderately prominent, the

surface smooth; elytra finely punctate-striate, the punctures becoming finer behind and not quite

reaching the apex, the interstices without setiferous impressions and smooth and flat throughout, the

apices slightly pointed ; beneath varying in colour from piceous to piceo-testaceous, smooth ; legs varying

in colour from piceous to testaceous, the femora smooth and glabrous.

formis, from Brazil, which is contained in the British Museum, leaves no room for

doubt that Calophthalmus, Thoms., is synonymous with it; moreover, the few words

of description gived by Gray,—“ Antenne nearly as long as the head and thorax, much

serrated ; palpi with the last joints securiform ; thorax square; the body in the form

of an elongate cone,”—point conclusively to the same genus. In Gemminger and

Harold’s Catalogue, Stilpnonotus is erroneously given as a synonym of Eurypus,

Kirby. Tenebrio nitens, Oliv., and Hurypus cupripennis, Pascoe, both from Brazil,

probably belong to Stilpnonotus. Thomson included two very closely allied species

in his genus Calophthalmus, one from Mexico and the other from Brazil; the latter

is possibly not distinct from 8. ewrypiformis. The recently described Calophthalmus

tenuicornis, Fairm., from Minas Geraes, cannot be included in this genus. In addition

to the species from Mexico, we have now to record another from Nicaragua.

1. Stilpnonotus mexicanus.

Calophthalmus mexicanus, Thoms. Musée Scient. p. 21, t. 8. figg. 1-1c".

Hab. Mexico}, Cordova (Sallé), Misantla, Jalapa (//6@e).

Our numerous examples vary from 74-13 millim. in length. The Brazilian species

are extremely closely allied to S. meaicanus, and apparently only differ from it in the

rather different punctuation of the upper surface. One of these, Calophthalmus post-

signatus, Fairm., from Minas Geraes, is very closely allied to S. mexicanus, most of our

examples of which have the thorax deeply impressed in the middle at the base and the

elytra with a common sutural black patch near the apex, characters stated by Fairmaire

to be peculiar to S. postsignatus.

2. Stilpnonotus thomsoni. (Tab. IV. fig. 1.)

Piceo-castaneous, shining, the elytra castaneous, the prothorax (and the elytra indistinctly) with a greenish-

eeneous tinge. Head finely and densely punctured; antenne piceous, short, not reaching to the base of

the prothorax, joints 4-10 strongly serrate; prothorax densely and not very finely punctured, the depres-

sion in front of the scutellum very deep; scutellum distinctly punctured ; elytra widest a little beyond

the middle, and thenee converging to the apex, the surface very closely and moderately finely punctured ;

legs reddish, the tarsi piceous ; beneath piceo-castaneous (the ventral surface lighter), with a greenish-

eeneous tinge, and closely and not very finely punctured.

Length 10 millim.

Hab. Nicaraava, Chontales (Janson).

A single example, contained in Mr. F. Bates’s collection. This species is closely

allied to S. mexicanus, but differs in the very much closer punctuation of the upper

and under surfaces, and also in having the elytra more obliquely narrowed behind (in

S. mexicanus they are much wider towards the apex) and comparatively less elongate.

As in §. meaicanus, the transverse scutellum is surrounded by a groove and appears to

be raised; and the elytra are strongly margined at the base and have a large and deep

depression on each side within the humeri.

Fam. MELANDRYIDZ.

This is a family numerous in genera and species in the Palearctic and Nearctic

Regions, and also in the temperate parts of the southern hemisphere. Comparatively

few inhabit the tropics, either of the Old or of the New World. One species only

has hitherto been described or noticed from Central America, whence we now record

forty-one. A considerable number of genera (and a few species also) are common to the

northern parts of Europe and North America, some of these also inhabiting Japan; and

the general distribution of the majority of the genera of the Melandryide is more

extended than in the other families of the Heteromerous Coleoptera. Polypria, Chevr.,

and several new genera here described are more or less intermediate between the

Melandryide and the Pythide, and they are accordingly placed at the end of the

family.

In the Melandryide and the following families of the Heteromera to be treated in

this work the anterior coxal cavities are widely open behind; in all the preceding

groups or families, the Ischyomiides (which I am now inclined to place at the end of

the Melandryide) and the Nilionide excepted, they are closed behind.

The earlier stages of these insects are no dowbt passed in decaying timber or in the

fungoid growths attached thereto.

EUSTROPHUS.

Eustrophus, Latreille, Régne anim. 1st ed. iii. p. 304 (1817); Lacordaire, Gen. Col. v. p.541; Horn,

Trans. Am. Ent. Soc. xv. p. 82.

This widely-distributed genus has one or more representatives in Europe, Japan,

Madagascar, East Africa, and North America; three inhabit Central America. ustro-

phus has recently been divided by Dr. Horn, certain of the rather numerous North-

American species being referred to a new genus, Holostrophus; the latter is not repre-

sented in our fauna. In one of the three species from Central America the mesosternum

is distinctly keeled in front, though it is not longitudinally raised to the level of the

prosternum, and received by it as in the following genus; all three have the prosternum

narrowed behind, instead of being parallel between the cox and prolonged to meet

the mesosternum as in Hustrophopsis.

1. Eustrophus arizonensis.

The three examples received from Mexico agree closely with Dr. Horn’s description

of E. arizonensis; they have the flanks of the prothorax densely and roughly punctured,

and the eyes narrowly separated. The punctures of the elytral series in the Sonora

examples are coarser than the description would lead one to expect, but in the Jalapa

specimen they are finer. In the absence of further material it is not advisable to treat

these as distinct.

2. Kustrophus marginatus. (Tab. IV. fig. 2.)

Oblong ovate, moderately narrowed behind, castancous or fulvous, a large transverse patch (sometimes divided

down the middle into two) on the disc of the prothorax, and the whole of the disc of the elytra from the

base nearly to the apex and laterally to the eighth row of punctures, piceous-black, the entire surface

thickly clothed with rather long brownish pubescence, shining. Eyes large, approximate ; antenne with

joints 1-4 ferruginous, 11 flavous, 5-10 black or brownish-black, 6-9 rather longer than broad, 10 about

as broad as long; prothorax very finely and closely punctured, the basal fovew feebly indicated and with

a few coarsish punctures laterally; elytra (if viewed from above) forming a continuous outline with the

prothorax, moderately coarsely striate-punctate, the punctures continued to the apex and quite distinct

from those of the interstices, the latter flat, and very closely and finely punctured; beneath castaneous or

reddish, very closely and finely punctured and pubescent, the venter still more densely punctured ;

prosternum narrowed behind and not prolonged to meet the mesosternum, the latter keeled, but declivous

in front; legs ferruginous, the four hinder tibia strongly transversely ridged on their outer edge.

Length 53-6 millim.; breadth 23-37 millim.

Hab. Mexico, Cordova, Playa Vicente (Sallé), Vera Cruz (Sallé, Hoge), Jalapa (Hoge) ;

GuaTEeMaLa, Yzabal (Sallé); Panama, Bugaba (Champion).

This species differs from the allied forms in having the thorax on all sides and the

elytra from the base to the apex broadly margined with fulvous or castaneous. It is

less narrowed behind than the North-American £. bicolor. The mesosternum is

distinctly keeled in front, the species thus differing from typical Hustrophi, but not to

the same extent as in Eustrophopsis, the anterior face of the keel being declivous and

not vertical. Labelled Hustrophus marginatus, Chevr., in the Sallé collection.

3. Eustrophus ovatus. (Tab. IV. fig. 3.)

Ovate, castaneous, strongly narrowed posteriorly, the disc of the prothorax indeterminately suffused with

piceous, the sides of the elytra from the base to the apex broadly and indeterminately fulvous, the entire

surface thickly clothed with rather long fulvous pubescence, shining. Eyes large, approximate ; antenne

with joints 1-4 ferruginous, 11 yellow, 5-10 black, 6-9 rather longer than broad, 10 about as broad as

long, 11 much longer than 10 ; prothorax very finely and closely punctured, the basal fovezx indistinctly

indicated and with a few coarsish punctures laterally; elytra forming a continuous outline with the

prothorax, moderately coarsely striate-punctate, the punctures continued to the apex, the interstices flat,

and very finely and closely punctured ; beneath castaneous ; prosternum narrowed almost to a point

behind, the mesosternum slightly keeled but declivous in front; legs ferruginous, the four hinder tibie

strongly transversely ridged on their outer edge.

Length 53 millim.; breadth 23 millim.

Hab. Guatemata, Zapote (Champion).

A single example. This species is allied to #. marginatus, but is much more ovate

in shape, the elytra being strongly narrowed behind. . ovatus is still more ovate in

shape than the North-American EZ. bicolor, and is also less elongate than that insect.

The differently-shaped prosternum will distinguish E. ovatus from Eustrophopsis.

EUSTROPHOPSIS.

Last joint of the maxillary palpi moderately long, subcylindrical, obliquely truncate at the apex, that of the

labial palpi oblong ovate; mentum trapezoidal, as long as broad; ligula prominent, deeply emarginate,

broadly rounded on each side in front; maxille with the outer lobe broad, the inner lobe short and very

narrow; mandibles strongly bifid; labrum prominent, rounded in front; head vertical; eyes deeply

emarginate in front, variable—usually very large and approximate, or narrowly separated, sometimes

smaller and more distant; antenne rather short11-jointed—4 shorter than 5, 5-11 much broader and

flatter than the others, 11 ovate and longer than 10; prothorax strongly transverse, rapidly narrowing

from the base, with shallow or indistinct basal fovee, the base bisinuate and with strongly produced

median lobe; scutellum rather large; elytra the width of and forming a continuous outline with the

prothorax at the base, with or without serial rows of punctures; coxe widely separated; prosternum

broad, horizontal, parallel or nearly so between the cox, prolonged behind, the apex broad and more or

less deeply emarginate to receive the sharply keeled produced mesosternum, the latter raised in the

middle to the level of the prosternum, vertical in front, acuminately prolonged behind, and its apex

received in the longitudinal median groove of the metasternum; legs moderately long, the penultimate

joint of the tarsi not lobed, the anterior tarsi not dilated in the male, the four hinder tibie with trans-

verse ridges on their outer edge ; tibial spurs moderately long, equal in length, and not pectinate beneath,

those of the hind pair not longer than those of the intermediate pair; first joint of the hind tarsi nearly

as long as the following joints united; form ovate or elliptical, broad, convex.

This genus is proposed to include numerous Tropical-American species, most of which

are undescribed as yet. Orchesia 15-maculata, Casteln., may be taken as the type*,

and Eustrophus ochraceus, Motsch., is also here referred to it. Hustrophopsis is closely

allied to Hustrophus and Holostrophus, from both of which the differently-formed

pro- and mesosternum sufficiently distinguish it. The South-American Pseudorchesia,

Fairm., possesses some characters in common with Hustrophopsis, but differs from it in

the much smaller scutellum and other particulars; moreover, no mention is made in the

description of the broad and ovate shape, characteristic of Eustrophopsis, but not of

Orchesia, to which genus Pseudorchesia is compared by Fairmaire. Two sets of species

are indicated in the present genus, one (to which O. 15-maculata and several other

spotted species belong) with the serial rows of punctures on the elytra obliterated

(though usually represented by fuscous dots, apparently caused by the punctures being

present on the under instead of the upper surface, and showing through), and the

other with the rows of punctures present. The apex of the prosternum is very deeply

and angularly emarginate in our species and in 0. 15-maculata, but more shallowly so, or

even subtruncate, in some others from tropical South America. Five species are here

enumerated from Central America, one of which appears to be very widely distributed.

Abraded examples have much the appearance of certain Platydema and other Diaperides

inhabiting the same districts; and, like many of the Diaperides, they are found about

fungi on decaying trees.

* The differences between this species and Orchesia are noted by Lacordaire, Gen. Col. v. p. 543, nota

1. Elytra without serial rows of punctures.

a. Prothorax and elytra spotted.

1. EHustrophopsis nigromaculatus. (Tab. IV. fig. 4.)

Oblong ovate, strongly narrowed posteriorly, pale flavous or flavo-testaceous, the prothorax with an elongate

spot on each side at the base, the elytra with the suture, two transversely placed spots on the disc of each

below the base, two similar ones below these (the inner one much the largest, and sometimes confluent

with the opposite one at the suture), a broad angular band (not reaching the lateral margin but usually

confluent with the opposite one at the suture) a little behind the middle, and a common triangular patch

before the apex, and the scutellum, black, the surface shining and thickly clothed with yellowish

pubescence. Antenne long, black, the outer half of the apical joint yellow, joints 5-11 flattened and

rather broadly dilated; eyes very large, approximate; prothorax very finely, shallowly, and closely

punctured, the basal fovez oblique, rather distinct, and with a few coarser punctures; elytra closely,

finely, and uniformly punctured (more distinctly so than the prothorax), without rows of impressed

punctures on their external surface, the punctures represented by irregular rows of fuscous dots showing

through from the under surface ; beneath finely and closely punctured, the prothorax, the metasternum in

the middle in front, and the venter, flavous or reddish-testaceous, the rest piceous ; prosternum broad and

parallel between the cox, the apex very deeply and angularly emarginate ; legs piceous or piceous-brown,

the tarsi of a more ferruginous tint.

Length 73-83 millim.; breadth 32-4 millim.

Hab. Guatemata, El Tumbador, Zapote (Champion).

Of described species, L. nigromaculatus can only be compared with the widely-dis-

tributed H. 15-maculatus; the latter has sixteen spots (the one in front of the scutellum

not having been counted by the author), four on the thorax and six on each elytron

(including one on the shoulder, which is absent in L. nigromaculatus). Five specimens.

b. Elytra with the disc indeterminately piceous.

2. Kustrophopsis rotundatus. (Tab. IV. fig. 5.)

Rotundate ovate, broad, reddish-castaneous, the disc of the elytra broadly and indeterminately suffused with

piceous on each side of the suture, the surface densely clothed with rather long fulvous pubescence, and

shining. Antenne moderately long, joints 1-4 fulvous, the extreme apex of the apical one ferruginous,

the rest black, 5-11 very broadly dilated and flattened, 9 and 10 transverse; eyes moderately large,

separated by a space about equal to the portion of the eye visible from above; prothorax very finely

punctured, the basal fovese shallow and with two or three coarser punctures; elytra closely, finely, and

uniformly punctured (more distinctly so than the prothorax), without trace of serial rows of punctures ;

beneath reddish-castaneous, finely and closely punctured; prosternum very broad between the coxe, the

apex narrowly and deeply emarginate; legs the same colour as the body.

Length 54 millim.; breadth 3? millim.

Hab. Panama, Volcan de Chiriqui 3000 feet (Champion).

This remarkably distinct species may be easily identified by its rotundate shape and

very broadly dilated outer joints of the antenne. From F. ochraceus it also differs in

its much smaller and widely separated eyes, absence of serial rows of punctures on the

elytra, and still broader and less parallel prosternum.,

or testaceous, 5-10 black; eyes very large, narrowly separated; prothorax very finely punctured, the

basal foves shallow and with a few coarser punctures; elytra finely striate-punctate, the punctures

becoming finer posteriorly, but continued to the apex, the interstices closely and finely punctured; beneath

finely and closely punctured, varying in colour—in dark-coloured individuals fulvo-castaneous with the

metasternum stained with piceous, in light-coloured ones entirely flavo-testaceous; prosternum broad

and parallel between the coxe, the apex very deeply and angularly emarginate; legs fusco-testaceous or

testaceous.

Many specimens. This insect is very widely distributed in Tropical America. The

three examples before me from the Amazons agree perfectly with the others from our

region; and there is little doubt that these are referable to Motschulsky’s species. The

eyes are less approximate than in /. nigromaculatus, and the antenne are also consi-

derably shorter. Motschulsky gives the length as 33 lines.

3. Elytra striate-punctate, the punctures not distinctly continued to the apex.

4, Kustrophopsis discoideus. (Tab. IV. fig. 7.)

Ovate, moderately broad, reddish-testaceous, the prothorax with a large patch on the basal half of the disc

(interrupted down the middle by a stripe of the ground-colour), and the elytra with the disc broadly from

a little below the base nearly to the apex (leaving a broad margin on all sides of the ground-colour), black,

the surface shining and thickly clothed with fulvous pubescence. Antenne moderately long, joints 1-5

testaceous, the apical half of 11 yellow, the rest black, 5-11 moderately dilated ; eyes very large, approxi-

mate; prothorax very finely and shallowly punctured, the basal fovez scarcely indicated ; elytra very finely

striate-punctate, the punctures not distinct to the apex, the interstices closely and finely punctured

(much more distinctly so than the prothorax); beneath reddish-castaneous, the metasternum a little

darker, closely and finely punctured; prosternum parallel between the coxe, the apex deeply and angularly

emarginate ; legs reddish-testaceous. a

Hab. GuaTEMALA, Zapote (Champion).

Two examples. ‘This species differs from the others of the genus here noticed not

only in the colour of the upper surface, but in having the elytra very finely striate-

-punctate, the punctures on the apical portion of the disc not distinct from those of the

interstices; the antenne have the five basal joints and the outer half of the apical

one flavous.

80 - HETEROMERA.

5. Eustrophopsis bipunctatus. (Tab. IV. fig. 8, var.)

Ovate, moderately broad, flavous or testaceous, the elytra each with a transverse black spot on the disc before

the middle, this spot sometimes largely and obliquely extended inwardly and also posteriorly (in one

example confluent with the opposite one at the suture and forming a large common postmedian patch),

the surface shining and densely clothed with yellowish pubescence. Antenne with joints 1-5 and the

outer half of the apical one testaceous, the rest black, 5-11 moderately dilated; eyes very large and

approximate; prothorax very finely and shallowly punctured, the basal fovex indistinctly indicated ;

elytra very finely striate-punctate, the punctures not distinct to the apex, the interstices closely and

finely punctured ; beneath reddish-testaceous, closely and finely punctured; prosternum parallel between

the coxe, the apex rather deeply emarginate ; legs testaceous.

Length 6-63 millim.; breadth 33-33 millim.

Hab. Mexico, Cordova (Sallé) ; Nicaracua, Chontales (Belt).

In the serial rows of punctures on the elytra being confused with the punctures of

the interstices towards the apex and in the coloration of the antenne this species

resembles H. discoitdeus; it may be distinguished from it, however, by its less convex

shape and the different system of coloration of the upper surface. The spot on the

disc of each elytron varies exceedingly in size in the five examples under examination ;

in two of them it is quite small. An undescribed species from the Amazons only

differs from . bipunctatus in having the serial rows of punctures on the elytra

completely obliterated.

ORCHESIA.

Trans. Am. Ent. Soc. xv. p. 37.

Clinocara, Thomson, Skand. Col. vi. p. 306 (1864).

Numerous species of this genus have been described from Europe, North America,

Chili, and Australia. O. 15-maculata, Casteln., as already stated, is referable to Eus-

trophopsis. One is here recorded from Guatemala, this being the only true Orchesia

known as yet from the tropical zone *; the genus is doubtless represented in Mexico.

The exceedingly long spurs to the hind tibie, of equal length and pectinate beneath,

are very characteristic.

1. Orchesia guatemalensis. (Tab. IV. fig. 9.)

Elongate, strongly narrowed posteriorly, brown, castaneous, or fulvo-castaneous, thickly clothed with rather

coarse brownish pubescence. Eyes very narrowly separated; antenne slender, comparatively long,

gradually widening outwardly, the penultimate joints longer than broad, ferruginous or testaceous :

prothorax densely and very finely punctured, the punctuation coarser at the base, the basal fovee only

indistinctly indicated; elytra narrowing from a little below the base, very finely, densely, and somewhat

roughly punctured, the punctuation coarser at the extreme base and finer towards the apex; beneath with

the sides and side-pieces of the metasternum densely and roughly punctured, the venter very densely and

ferruginous.

Length 33-42 millim.

Hab. Guatemata, San Gerénimo, El Tumbador (Champion).

‘Four examples. ‘This species is, no doubt, closely allied to the North-American

O. gracilis, Melsh., the prosternum being similarly shaped; but, to judge from Dr.

Horn’s description of that insect, O. guatemalensis is still more narrowed posteriorly.

The form of the antenne of O. gracilis is not mentioned by Melsheimer or Dr. Horn ;

these organs are comparatively long and slender in O. guatemalensis, the species

differing considerably from the allied European forms in this respect.

MICROSCAPHA.

Microscapha, Leconte, New species Col. p. 152 (1866).

This genus was established by Leconte upon a single species from Illinois and |

Georgia; a second from Central America is here described. Microscapha is allied to .

Orchesia, but easily distinguished from it by the antenne being clubbed and having a

very stout second joint, and the maxillary palpi differently shaped. Both species are of

ovate shape and very small.

1. Microscapha minuta. (Tab. IV. fig. 10.)

Ovate, convex, sparsely pubescent, shining, black or piceous-brown, the front of the head, oral organs, antenne,

and legs testaceous. Prothorax very minutely and sparsely punctured ; elytra very finely, distinctly, and

rather closely punctured, without trace of serial rows of punctures.

Length 13 millim.

Hab. Mexico, Jalapa (Hoge); GuatemaLa, Chacoj in Vera Paz (Champion).

One example from each locality, both, unfortunately, in a mutilated condition.

M. minuta seems to agree precisely in structure with J. clavicornis, from which it

apparently only differs in its punctured elytra and considerably smaller size. . clavi-

cornis is described as “ fere impunctata,” whereas in V/. minuta the elytra are finely but

quite distinctly punctured.

CUPHOSIS.

Maxillary palpi very strongly serrate, the apical joint very long and securiform, the second and third joints

acutely produced at their inner apical angle and with their apical side deeply arcuate-emarginate, the

third joint only about half as long as the second; last joint of the labial palpi short, ovate; mentum

rather broader than long, widest behind; maxille with the inner lobe exceedingly narrow, the outer lobe

moderately broad; mandibles entire at the apex, without trace of tooth on the lower side; labrum

prominent, rounded in front; head vertical, the epistoma not defined; eyes large, not prominent,

emarginate in front; antenne very long and filiform, tapering a little outwardly, 11-jointed—3-11 very

elongate, almost equal in length, 3 about as long as 1, but very much more slender; prothorax about

as long as broad, convex, a little rounded in front (if viewed from above), strongly bisinuate at the base,

the basal foveee indistinctly indicated ; scutellum moderately large; elytra about as wide as the prothorax

at the base, exceedingly elongate, narrowing from the base to the apex; anterior coxe contiguous, the

cavities closed externally; prosternal episterna without well-defined suture in front, and not separated

from the prosternum ; middle coxe separated by the mesosternum, the latter long and slightly keeled

in front, the mesosternal epimera very sharply defined and extending to the cavities and closing them

externally ; metasternum long; legs very long, the four hinder tarsi exceedingly elongate, the four hinder

tibie with a series of coarse transverse ridges on their outer edge, the first joint of the posterior tarsi

equal in length to the second and third joints united; front, middle, and hind tibie with spurs of unequal

length (those of the hind pair only a little longer than those of the middle pair), one very long, the

other considerably shorter, both strongly pectinate beneath ; anterior tarsi broadly dilated in the male, the

penultimate joint of the anterior and intermediate pairs feebly lobed beneath (that of the anterior pair

strongly so in the male), the corresponding joint of the hind pair simple; claws slender, slightly

dilated at the base; body very elongate, narrow, and cuneiform, strongly compressed laterally beneath.

This interesting new genus contains a single widely distributed species, which ranges

from Mexico to the Amazons. In the structure of the maxillary palpi, Cuphosis very

nearly agrees with Serropalpus, Dentipalpus, and Ctenoplectron, but differs from each of

these in several important structural characters; in the pectinate tibial spurs it

approaches Orchesia. Cuphosis may be at once identified from all these allied genera

by its very elongate cuneiform shape, long and slender limbs, unequal and pectinate

tibial spurs, and strongly transversely ridged tibie. ‘The inner lobe of the maxille

is very narrow, much narrower than in Serropalpus. Closely allied forms inhabit

Australia. ‘Though so widely distributed, the insect appears to be everywhere very rare.

silky pubescence. Head very finely and closely punctured; antenne reaching to about the middle of the

elytra, fusco-testaceous; prothorax a little rounded at the sides, slightly narrowed in front, the hind

angles cbtusely rectangular, the sides finely margined from the base to a little before the middle, the disc

usually canaliculate and with a large and very shallow impression on each side a little behind the middle, the

surface very finely, densely, and uniformly punctured, the pubescence usually of a browner or more fulvous

colour in places, in some examples of a unicolorous ashy tint; elytra with a sharp sutural stria and very

shallow longitudinal grooves, in some examples with a longitudinal series of broad shallow transverse depres-

sions across the disc, the surface very finely and densely punctured, the punctuation becoming a little coarser

and more crowded at the base, on the shoulders assuming the form of transverse rugs, and more scattered

Very elongate, cylindrical, a little flattened above, varying in colour from ferruginous-brown to dark brown,

opaque, the entire upper surface very finely, uniformly, and densely punctured, and densely clothed with

short brownish or fulvous pubescence. Antenne in the male moderately long and slender, and with the

outer joints much longer than broad, in the female shorter and stouter, ferruginous; maxillary palpi very

long, the apical joint very elongate and securiform, and nearly twice as long as the elongate-trian-

gular second joint, the third joint rather narrower than the second; prothorax obliquely narrowed

anteriorly, the sides margined from the base to beyond the middle, the dise often with one or two

almost obsolete depressions on each side and a fine, slightly raised, central line, and sometimes feebly

impressed in the middle before the base, the base strongly bisinuate; elytra without trace of shallow

longitudinal grooves or cost, the punctuation uniform throughout (or, rarely, a little more rugose at -

the base on each side of the scutellum, but not at the shoulders), the apices obtuse; beneath finely and

densely punctured and densely pubescent; prosternal episterna limited anteriorly by a sharp oblique carina

extending from the anterior edge of the prothorax to the anterior coxe, the latter with the lateral

cavities closed; legs ferruginous, the outer edge of the four hinder tibise without transverse ridges;

Elongate, subcylindrical, piceous-brown, subopaque, somewhat thickly clothed with brownish pubescence.

Head densely and finely punctured; antenne (3) moderately long, not very slender, the joints much

longer than broad, piceo-testaceous; maxillary palpi(¢) with the second and third joints strongly dilated

internally and rather short, the apical joint securiform and about twice as long as the second; prothorax

longer than broad, the sides narrowly margined from the base to the apex, gradually narrowed in front,

and feebly rounded, the hind angles obtuse, the surface densely and finely punctured, with a shallow

transverse impression in front of the scutellum, and an indistinct oblique one on each side at the base, the

base only very feebly bisinuate; elytra with shallow longitudinal grooves, punctured at the base (and

shoulders) like the prothorax, the punctuation becoming finer, shallower, and more scattered beyond the

middle, the apices rounded; beneath finely and densely punctured and sparsely pubescent; prosternal

episterna limited anteriorly by an oblique carina extending from the anterior edge of the prothorax to the

anterior coxe, the latter with the lateral cavities completely closed ; legs ferruginous, the hinder tibie

without transverse ridges; ventral segments 1-4 each with a broad, transverse, densely pubescent patch in

the middle, the apical margin of the fifth feebly emarginate, and the anterior tarsi moderately dilated, in

the male.

Length 5% millim. (¢.)

Hab. Panama, Volcan de Chiriqui 4000 feet (Champion).

One male example. This small species is allied to D. vawdoweri (Muls.), an insect

inhabiting Europe and North America, but is much smaller and has the upper surface

more finely sculptured. The much more elongate apical joint to the maxillary palpi

and the more widely separated middle coxe distinguish it from Xylita.

There is a mutilated example of this species contained in the Sallé collection and

labelled as from Mexico, without more definite locality. The species is therefore

included in our list, though this southern habitat undoubtedly requires confirmation.

** Prosternal episterna not limited anteriorly by an oblique keel; antenne very long and

slender ; hinder tibie transversely ridged on their outer edge.

pubescence. Head finely and very densely punctured; antenne (¢) very long and slender (extending to

beyond the middle of the elytra), joints 4-11 exceedingly elongate, ferruginous ; maxillary palpi(d)

with the second joint one and a half times the length of the apical joint, the latter securiform and about

one third longer than the elongate-triangular third joint; prothorax longer than broad, the sides margined

from the base to the apex, narrowed in front, and a little rounded behind, the surface very densely and

finely punctured, and with a very shallow impression on each side at the base, the disc with traces of a

_ smooth central line, the base strongly bisinuate; elytra flattened on the disc towards the base, with well-

marked sutural stria and shallow longitudinal grooves, the surface very finely and densely punctured, the

punctures becoming coarser and still closer towards the base, granular, more scattered, and here and there

transversely confluent at the shoulders, and finer and more distant towards the apex, the apices obtuse ;

beneath finely and densely (the metasternum in the middle more coarsely and roughly) punctured and

pubescent, the ventral surface densely and uniformly so; prosternal episterna not separated from the

anterior portion of the prosternum ; legs fusco-ferruginous, the outer edge of the four hinder tibie with a

series of transverse ridges; apical margin of the fifth ventral segment produced in the middle and with its

apex truncate, and the anterior tarsi broadly dilated, in the male.

Length 14 millim. (¢.)

Hab. Mexico, Santecomapan (Sallé).

A single male example. This species has a very elongate second joint to the

maxillary palpi, and exceedingly long and slender antenne, characters of almost

generic importance, but agrees very closely in other respects with Dircwa; it is

accordingly included, provisionally, in this genus. The very elongate antenne, rugose

shoulders, ridged hinder tibie, &c., distinguish D. longicornis from D. mexicana. The

oblique ridge limiting the prosternal episterna anteriorly is not present in D. longi-

cornis. In the form of its antenne, tibie, &c., D. longicornis closely approaches the

Chilian genus Dentipalpus.

XEUXES.

Maxillary palpi with the apical joint cylindrical and moderately long, the second and third joints subtriangular ;

last joint of the labial palpi narrow, oblong ovate; mentum about as long as broad, widest behind ;

mandibles entire at the apex, but with a short, blunt tooth on the lower side beneath ; labrum prominent ;

head broad, vertical, the epistoma not distinctly defined; eyes convex, deeply emarginate in front ;

antenne short, passing a little beyond the base of the prothorax, 11-jointed—3 triangular, longer than 4,

4-10 short and strongly serrate, 5-8 the widest, 11 ovate and narrower and longer than 10; prothorax

broad and strongly transverse, with deep basal foves:; scutellum large; elytra depressed, moderately

long, very little wider than the prothorax, broadly rounded at the shoulders, subparallel to beyond the

middle; anterior coxe separated by the prosternum, the latter rounded off behind, the cavities closed

externally and without lateral fissure; prosternal episterna with well-defined suture in front; middle

coxee narrowly separated, the cavities open externally, and the trochantin visible; metasternum long; legs

slender ; tibial spurs short; tarsi slender, the penultimate joint not lobed or dilated, the first joint of the

posterior pair the length of the other three joints united ; claws slender, a little dilated at the base; form

elongate, rather depressed.

This genus is proposed to include a single species from North-western Mexico. It

is perhaps nearest allied to the recently-described Mallodrya, Horn, from the United

States, though approaching Melandrya &c. The chief characters of Xewxes are the.

short, serrate antenne, simple tarsi, short tibial spurs, and cylindrical apical joint of the

maxillary palpi. The maxille are formed very much as in Dircea.

86 HETEROMERA.

1. Xeuxes brevicollis. (Tab. IV. figg. 15,2; 15a, labium; 15 6, maxilla and

maxillary palpus; 15 c, mandible; 15d, antenna.)

Black, somewhat thickly clothed with very short pubescence, feebly shining. Head very finely and closely

punctured ; antenne brownish-black ; prothorax broad, strongly transverse, the sides very finely margined

from the base to the apex, a little narrowed in front, and rounded, the hind angles obtuse, the base

bisinuate and finely margined, the apex (if viewed from above) truncate, the surface closely and moderately

finely punctured (more coarsely so than the head), with an impression on each side just behind the

eyes (in a line with the deep longitudinal basal foves) and an interrupted smooth narrow groove down

the middle; elytra distinctly depressed within the shoulders, and with very shallow longitudinal grooves on

the disc, the surface very closely, finely, and uniformly punctured, the apices rounded ; beneath brownish-

black, finely and closely punctured, sparsely pubescent ; legs piceous-brown.

Length 63 millim. (9.)

Hab. Mexico, Ciudad in Durango (Hége).

Two examples, apparently both females, were captured by Herr Hoge during his

second expedition.

DRANCES.

Maxillary palpi with the second joint rather long, subtriangular, the third joint triangular, much shorter than

the second, the fourth joint large and triangular, longer than broad, its outer and apical sides about equal ;

labial palpi with the first joint small, the second joint very large and ovate, and with its apex obliquely

truncate, the third joint ovate, obliquely articulated to, and narrower than, though about as long as, the

second; mentum strongly transverse; ligula prominent, rounded in front; mandibles bifid; inner lobe

of the maxille rather narrow, the outer lobe moderately broad; head short and broad, subhorizontal,

the epistoma limited posteriorly by a shallow groove; eyes deeply emarginate, convex, moderately large,

very widely separated, a space in front of each raised for the insertion of the antenne; the latter

11-jointed, stout, and a little flattened, nearly reaching to the middle of the elytra, joint 3 three times as

long as and much broader than 2, rather shorter than 4, 4-10 longer than broad, 11 longer than 10, and

ovate; prothorax strongly transverse, broadly truncate in front, the sides dilated posteriorly, and rather

sharply separated from the flanks, the basal fovee not indicated, the base bisinuate ; scutellum transverse,

rather large; elytra long, a little wider than the prothorax at the base, the sides almost straight (though

gradually narrowing) to far beyond the middle, the apices separately rounded; anterior coxe contiguous,

the cavities closed externally, but widely open behind; middle coxse narrowly separated, the cavities open

externally, and the trochantin visible; legs rather long, moderately stout; penultimate joint of the tarsi

small, very feebly lobed beneath, the basal joint of the hind tarsi the length of the following joints united ;

form very narrow, elongate, rather depressed.

This genus is proposed for an inconspicuous insect from Mexico. Drances is

perhaps nearest allied to Symphora. The labial palpi differ in form from those of the

majority of the Melandryide in having the second joint very stout, stouter than the

apical one, and with its apex very obliquely truncate.

1. Drances angustatus. (Tab. IV. figg. 16; 16a, labium; 160, maxilla and

maxillary palpus; 16 c, mandible.)

Black, the front of the head and the oral organs fusco-ferruginous, sparsely pubescent, slightly shining. Head

very closely and coarsely punctured; antenne black; prothorax very closely and coarsely punctured,

broadest at the base, the sides almost straight behind, and rounded and a little narrowed in front, the

hind angles rectangular, the disc with traces of a very shallow oblique groove on each side behind; elytra

with very shallow intrahumeral depression, punctured like the prothorax, and without trace of serial rows

of impressions ; beneath piceous-black, the sides of the pro- and metasternum densely and somewhat

coarsely, the rest of the surface more sparsely, punctured; legs piceous-black, closely and roughly

punctured.

Length 44 millim.; breadth 14 millim.

Hab. Muxico, Guanajuato (Sailé).

One example, possibly a male.

SYMPHORA.

Symphora, Leconte, New species Col. p. 150 (1866).

Two species of this genus have been described, both from the United States; seven

are now added from Central America, of five of these single examples only have been

captured. The last joint of the maxillary palpi varies a little in shape in our species,

it being rather short and with the outer and apical sides more rounded in S. ruficeps

and more elongate and with the outer side straighter in 8. maculata. The penultimate

joint of the tarsi is feebly but distinctly lobed beneath in §. maculata, but in our other

species it is not or only very indistinctly lobed. The eyes also vary in size, 2. e. they

are moderately large and very prominent in S. maculata, and very small in S. ruficeps ;

in the North-American S. flavicollis they are larger than in either of the Central-

American species. With our very limited amount of material it is not advisable to

treat these differences as generic. These insects are of small size and have somewhat

the facies of Anaspis.

They are found about fallen trees.

1. Prothorax with an oblique groove on each side behind.

1. Symphora tropicalis. (Tab. IV. fig. 17.)

Moderately elongate, not very convex, varying in colour from piceous-black to brown, the head (the eyes

excepted), the prothorax above and beneath, and the oral organs reddish- or flavo-testaceous, sparsely

pubescent, shining. Head closely and finely punctured, the eyes rather small, very widely separated ;

antenne moderately long, the four basal joints, and usually the apical one also, testaceous, the rest

piceous ; prothorax strongly transverse, the sides slightly rounded anteriorly, narrowed in front, and

almost straight behind, the disc with an oblique deep groove on each side behind the middle, the surface

densely and somewhat coarsely punctured ; elytra rather long, subparallel to about the middle and thence

rapidly narrowed to the apex, very closely and moderately coarsely punctured; beneath very densely and

finely punctured, the metasternum almost smooth in the middle; legs testaceous, the tarsi sometimes a

little darker.

Length 23-3 millim. (¢ 2.)

minately defined) fusco-testaceous.

Hab. GuatemaLa, San Gerénimo (Champion).

Five examples, including one of the variety. These differ a little inter se, but are,

no doubt, all referable to one species. /. tropicalis closely resembles S. flavicollis, Lec.,

88 HETEROMERA.

two specimens of which from Texas are before me, but may be distinguished from it by

its smaller and more widely separated eyes, finer and more closely punctured elytra,

and rather more elongate shape. Though variable in colour S. tropicalis invariably

has the elytra darker than the head and thorax. S. rugosa, Lec., is unicolorous and

has a much more rugose and less convex thorax.

2. Symphora impressicollis.

Closely resembling S. tropicalis and differing as follows:—The antenne entirely testaceous; the prothorax

more convex, more rounded at the sides, scarcely narrower at the apex than at the base, the surface

rather more coarsely punctured, the impressions deep; the elytra with the sutural region broadly and

indeterminately (still more broadly so towards the base) fusco-testaceous ; the under surface a little more

coarsely punctured.

Length 22 millim.

Hab. Mexico, Acapulco (Hége).

Though only a single example has been received of this insect it seems impossible to

treat it as a variety of S. tropicalis.

8. Symphora apicalis. (Tab. IV. fig. 18.)

Moderately elongate, not very convex, shining, sparsely pubescent, black, the head and oral organs, the prothorax,

the apex of the elytra, and the legs flavo-testaceous. Head very closely and moderately finely punctured,

the eyes small and very widely separated; antenne moderately long, joints 1-4 testaceous, the rest

piceous ; prothorax strongly transverse, not very convex, narrowing from the base, the hind angles sub-

rectangular, the disc with a large and deep oblique groove on each side, the surface densely and coarsely

punctured ; elytra subparallel to about the middle, narrowing thence to the apex, very closely and rather

coarsely punctured ; beneath coarsely and densely punctured. the ventral surface much more finely so, the

last two segments fusco-testaceous, the rest (except the head and prothorax) black.

Length 22 millim.

Hab. Panama, Volcan de Chiriqui 4000 feet (Champion).

One specimen. ‘This species closely resembles S. tropicalis, and, at first sight, would

appear to be only a colour-variety of that insect; it differs, however, in the more

coarsely punctured under surface, the metasternum, especially, having very much

coarser impressions. The thorax is narrowed from the base, and has the oblique

impression on each side of the disc larger and deeper, and (like the elytra) is also a

little more coarsely punctured.

4. Symphora ruficeps.

Moderately elongate, convex, sparsely pubescent, slightly shining, piceous-brown or brown, the head (except the

eyes) and the shoulders, and sometimes the sides of the prothorax and of the elytra (indeterminately), reddish-

' testaceous or testaceous. Head very closely and rather coarsely punctured, the eyes small and very widely

separated, the last joint of the maxillary palpi piceous; antenne moderately long, thethree or four basal joints,

and sometimes the apical one or two, testaceous, the rest piceous ; prothorax convex, transverse, narrowing

from the base, the disc with a rather shallow oblique groove on each side towards the base, the surface densely

and rather coarsely punctured ; elytra subparallel to about the middle, rather obtuse behind, very closely and

moderately coarsely punctured; beneath piceous-brown or piceo-castaneous, densely and not very finely

punctured; legs testaceous.

Length 23-3 millim. ( 9.)

Hab. Guatemata, Duetias (Champion).

Three examples, apparently including both sexes. This insect is more convex and more

obtuse behind than S. tropicalis &c.; the apical joint of the maxillary palpi is piceous in

colour, and has the outer and apical sides, and also the inner angle, more rounded.

5. Symphora maculata. (Tab. IV. fig. 19, ¢ .)

Elongate, not very convex, moderately shining, sparsely pubescent; flavo-testaceous, the prothorax with an

ill-defined stripe on each side of the disc, the elytra with a triangular scutellar patch (not including the

scutellum), connected along the suture with a common transverse band near the apex, and a rather large

lateral spot placed a little before the middle, and the eyes, black or piceous. Head closely and somewhat

coarsely punctured, the oral organs testaceous ; the eyes convex, prominent, and moderately large ; antenne

very long, extending to beyond the middle of the elytra, joints 1-3 flavo-testaceous, 4-11 piceous, the apical

joint a little lighter; prothorax moderately transverse, rather convex, the sides straight behind and

narrowing and rounded in front, the hind angles subrectangular, the dise with a deep oblique impression

on each side towards the base, the surface densely and rather coarsely punctured; elytra narrowing from

about the middle, closely and moderately coarsely punctured; beneath (the head excepted) piceous, very

closely and rather coarsely, the ventral surface more finely, punctured; legs entirely testaceous, the

penultimate joint of all the tarsi feebly lobed beneath.

Length 2? millim. (<¢.)

Hab. Guaremana, Cerro Zunil 4500 feet (Champion).

One male example only of this very distinct species was captured. The antenne are

much longer in S. maculata than in the other members of the genus.

2. Prothorax without oblique groove on each side behind.

6. Symphora convexa. ('[ab. IV. fig. 20.)

Moderately elongate, very convex, strongly narrowed posteriorly, above and beneath piceous-black, the head

anteriorly and the oral organs fusco-testaceous, sparsely pubescent, not very shining. Head finely and

closely punctured, the space between the eyes more sparsely so, shining, the eyes rather small; antenne

moderately long, black, the basal four joints fusco-testaceous; prothorax strongly transverse, convex,

narrowing from the base, the surface very densely and rugosely punctured and without impressions ;

elytra narrowing from a little below the base, very closely and rather coarsely punctured ; beneath closely

and coarsely punctured, the ventral surface much more finely so; legs brownish-black.

Length 3 millim.

Hab. Guatemata, Cerro Zunil 4500 feet (Champion).

A single example. Viewed laterally and longitudinally this insect is of a more

arcuate shape than any other species of the genus. The thorax is narrowed from the

base, very densely and rugosely punctured, and quite unimpressed. The elytra are

more narrowed posteriorly. than in the allied forms. S. convera closely resembles some

of the black species of Anaspis; but, apart from other differences, may be at once known

from such by the more slender tarsi, the first joint of the hind pair being exceedingly

elongate and longer than the three other joints united *.

* In our figures of this species and of S. apicalis and S. maculata the hind tarsi are incorrectly drawn: the

first joint should be more elongate and the other joints shorter (as in fig. 17).

7. Symphora elongata.

Elongate, convex, moderately narrowed posteriorly, brownish-black, the head (the eyes excepted) reddish-

testaceous, sparsely pubescent, slightly shining. Head finely and very closely punctured, the eyes moderately

large, the palpi fusco-testaceous; antenne long, the joints elongate, 1-6 testaceous, the rest piceous ;

prothorax convex, strongly transverse, the sides slightly rounded and narrowing from a little before the

base, the surface densely and rugulosely punctured and without impressions ; elytra narrowing from about

the middle, very closely and rather coarsely punctured; beneath (the head excepted) brownish-black,

closely and coarsely punctured, the ventral surface much more finely so; legs fusco-testaceous, the femora

and coxe flavo-testaceous.

Length 3 millim. (<¢.)

Hab. Guatemata, Capetillo (Champion).

One specimen. This species is closely allied to S. convexa, but differs from it in its

less arcuate shape (viewed laterally and longitudinally), much longer antenne, more

closely punctured head, and paler legs, and, more particularly, in the elytra being more

parallel and less narrowed behind.

Group SCRAPTIIDES.

CANIFA.

Canifa, Leconte, New species Col. p. 14-4 (1866) ; Leconte and Horn, Class. Col. N. Am. p. 399

(1883).

Leconte has separated the North-American Seraptie into three genera, Scraptia,

Allopoda, and Canifa, basing these chiefly upon differences in the shape of the apical

joint of the maxillary palpi and upon the lobing or not of the penultimate joint of the

tarsi. ‘Three species from Central America agree very well with Canifa in having the

apical joint of the maxillary palpi rather long and subcultritorm, the third joint of the

antennee very short in the male, the penultimate joint of all the tarsi lobed beneath,

and the first joint of the hind tarsi about twice as long as the following joints united ;

they are accordingly referred to that genus. For the other allied forms from our

region a new genus has been required. Four species of Canifa have been recorded, all

from the United States. In those from Central America here described the sexes show

a very marked disparity in the size of the eyes (at least in C. speciosa) and in the form

of the antenne *, the latter, as in certain species of Cistela, having the second and third

joints in the male very short and equal in length and together only about, or not much

more than, half as long as the fourth joint. Cteniacantha marginata, Qued., from Puerto

Rico, to judge from the description and figure (cf. Berl. ent. Zeitschr. 1886, pp. 119-

121), is, no doubt, very closely allied to the species here referred to Canifa; but these

latter have the mandibles strongly bifid (at least in C. speciosa), the apical joint of the

maxillary palpi only moderately elongate, and the tibial spurs not or scarcely pectinate,

characters not agreeing with Quedenfeldt’s description.

* This is not mentioned by Leconte.

CANIFA. 91

The species of this and of the following genus are found about the branches of

felled or decaying trees.

1. Canifa speciosa. (Tab. IV. figg. 21,3; 21a, labium; 210, maxilla and

maxillary palpus; 21 ¢, mandible.)

Elongate, subparallel, flavo-testaceous or testaceous, the elytra sometimes with a brownish or piceous ill-

defined sublateral stripe, sparsely pubescent, moderately shining. Head very coarsely and closely punc-

tured; eyes black—in the male very large and subapproximate, in the female smaller and much more

distant; antenne testaceous—in the male very long, fully reaching to the middle of the elytra, with

joints 2 and 3 very short and equal, 4 three or four times as long as 3, and 4-11 very elongate and sub-

equal—in the female shorter and more slender, and with joint 3 considerably longer than 2 and about half

the length of 4; prothorax transverse, the sides much rounded anteriorly and straight behind, gradually

narrowing from the base in some examples, the hind angles rectangular or subrectangular, the basal

foveee large and very deep, the disc usually more or less distinctly canaliculate, the base trisinuate, the

surface coarsely, closely, and roughly punctured; scutellum coarsely punctured; elytra long and sub-

parallel, closely and moderately coarsely punctured; beneath finely and rather sparsely, the sides of the

pro-, meso-, and metasternum densely, punctured; legs hairy, testaceous; the penultimate joint of all the

tarsi lobed beneath, that of the two front pairs broadly so; anterior tibie slightly, the intermediate tibie

more or less distinctly, sinuate in the male, the anterior pair in some examples slightly dilated on the

inner side near the base.

Length (with the head extended) 5-83 millim. (¢ 2.)

Hab. Mexico, Real del Monte in Hidalgo, Jalapa (Hédge); GuatemaLa, Coban

(Conradt), San Joaquin, Cerro Zunil 4000 feet (Champion).

Var. Prothorax not so coarsely or roughly punctured; the eyes less approximate and the anterior tibie

triangularly dilated on the inner side before the middle in the male.

Hab. Mexico, Omilteme 8000 feet, Xucumanatlan, Amula, and Chilpancingo in

Guerrero (H. H. Smith).

This species is not uncommon in Mexico and Guatemala, whence we have about

forty specimens. C. speciosa varies greatly, not only in size but in sculpture and in the

development of the male characters. In the examples from each of the localities

slight differences are to be found, though not of sufficient importance to be regarded

as specific. The antennee of the male are stouter than those of the female. In the

single male of. the variety the anterior tibie are triangularly dilated within and the

middle tibie are more sinuous; intermediate examples, however, occur. Some of

our specimens are of a piceo-testaceous colour, but this is probably due to discoloration.

The apical point of the labial palpi (as in Scraptia &c.) is transversely securiform and

exceedingly broad, its apical side very much longer than the outer side. A male from

Cerro Zunil (where examples of both sexes of the insect were captured in numbers) is

shown on our Plate.

2. Canifa oculata.

Elongate, narrowing posteriorly, above and beneath (the eyes excepted), antennz, and legs flavo-testaceous,

sparsely pubescent, slightly shining. Head very coarsely and closely punctured; eyes black, very deeply

emarginate in front (the ocular canthus extending more than halfway across), narrowly separated in the

male, more distant in the female; antenne moderately long, joints 2 and 3 in the male very short, equal

in length, and together not nearly so long as 4, joint 3 in the female half as long again as 2; prothorax

transverse, narrowing from the base, the sides much rounded in front, the hind angles acutely rectangular,

the basal fovese shallow, the disc sometimes obsoletely canaliculate, the base feebly bisinuate and almost

straight, the surface coarsely, closely, and roughly punctured ; scutellum coarsely punctured ; elytra widest

a little before the middle and narrowing thence to the apex, closely and moderately coarsely punctured ;

beneath finely and sparsely punctured, the metasternum coarsely so at the sides and smooth in the

middle; anterior and intermediate tarsi distinctly, the posterior tarsi very narrowly and indistinctly,

lobed beneath.

Length (with the head extended) 32-44 millim. (d 2.)

Hab. Guatemata, San Gerénimo 3000 feet (Champion); Panama, Volcan de Chiriqui

3000 feet (Champion).

Seven examples from Guatemala and two from the State of Panama. Smaller and

more narrowed behind than C. speciosa; the antenne shorter and more slender; the

eyes more deeply emarginate; the thorax with shallow basal fovee and the base more

truncate; and the penultimate joint of the hind tarsi indistinctly lobed. The last

ventral segment in the male has very long, curved, and greatly-developed lateral lobes.

8. Canifa circumdata. (Tab. IV. fig. 22, ¢.)

Moderately elongate, pallid testaceous, the sides and apex of the elytra, and the sides of the prothorax less

distinctly, piceous brown, sparsely pubescent, slightly shining. Head closely and coarsely punctured ;

eyes (¢) black, very deeply emarginate, narrowly separated; antenne ( ¢') pallid testaceous, rather stout,

joints 2 and 3 very short and equal, together about half the length of 4; prothorax strongly transverse,

about twice as broad as long, convex, narrowing from the base, the sides much rounded, the hind angles

rectangular, the basal fovee minute, transverse, and placed just within the margin, the disc shallowly

impressed in the middle towards the base, the surface closely, moderately coarsely, and rather roughly

punctured; scutellum similarly punctured; elytra widest about the middle, rather obtuse behind, more

sparsely and much more coarsely punctured than the prothorax; beneath testaceous, the venter stained

with piceous ; legs pallid testaceous; the penultimate joint of all the tarsi (that of the posterior pair less

distinctly) lobed beneath.

Length (with the head extended) 3 millim. (<¢.)

Hab. Gvatemata, El Tumbador 2500 feet (Champion).

One male example, captured on the Pacific slope of Guatemala. This small species

may be readily identified by its system of coloration. The thorax is comparatively

very short and has very minute basal fovee ; the elytra are comparatively more coarsely

punctured than in the two preceding species, the punctuation being considerably

coarser than that of the thorax.

EVALCES.

Last joint of the maxillary palpi elongate, subtriangular, its apical side much shorter than the outer side and

somewhat rounded ; last joint of the labial palpi broad ovate, its apex truncate; mentum about as long as

broad, sinuate at the sides, broadest behind; lobes of the maxille long, the inner one very narrow ;

mandibles simply unidentate; head vertical, comparatively narrow, rather long, a little rounded behind,

suddenly constricted into a neck as in Scraptia; eyes small, similar in both sexes, deeply emarginate in

EVALCES. 93

front; antenne rather short, moderately stout, similar in both sexes, joint 8 much longer than 2 and as

long as 4;° prothorax moderately transverse, strongly narrowed in front, the sides much rounded, the base

feebly bisinuate or subtruncate, the basal fovee quite shallow; anterior coxs contiguous, with very pro-

minent trochantin ; intermediate coxe contiguous; tibial spurs equal in length, slender; penultimate joint

of the anterior and intermediate tarsi very distinctly lobed, that of the posterior tarsi simple; first joint

of the posterior tarsi shorter than the following joints united.

Several species from Central America agree in the above particulars. In form the

labial palpi and mandibles are quite different from those of Scraptia and its allies.

Evalces agrees in some respects with Leconte’s description of Allopoda, but the latter

is expressly stated to have the labial palpi formed as in Scraptia and Canifa; 7. e. very

transverse, with the apical side longer than the others. All the species referred to

Evalces have the head less truncate behind and narrower and more elongate in shape

than in Scraptia &c.; three of them possess very well-marked male specific characters.

The genus bears a deceptive resemblance to Anaspis.

1. Evalces griseus. (Tab. IV. figg. 23,4; 23a, labium; 23, maxilla and

maxillary palpus; 23 c, mandible; 23 d, cedeagus.)

Elongate, narrow, piceous or piceous-brown, rarely testaceous with the prothorax slightly stained with piceous,

the elytra in the dark examples sometimes with an indistinct piceo-testaceous vitta extending from the

shoulder to the apex, sparsely pubescent, slightly shining. Head densely and rather coarsely punctured ;

antenne and maxillary palpi varying in colour from piceous to fusco-testaceous; prothorax convex, nar-

rowing from the base, densely, roughly, and moderately coarsely punctured; elytra very closely, finely,

and somewhat coarsely punctured ; beneath finely and densely punctured, the metasternum more sparsely

so; legs slender, fusco-testaceous or testaceous, the tibiz similar in both sexes; central sheath of the

cedeagus of the male stout and cylindrical to the end, curved, and armed at the apex beneath with

about four very sharp teeth directed backwards and above with a few bristly hairs, the apex blunt

(fig. 23 d).

Length (with the head extended) 3 millim. (¢ 9.)

Hab. GuateMALa, San Gerénimo, Panajachel (Champion).

Ten examples. In each of the five male specimens the cedeagus is extruded and

exhibits the above-mentioned marked peculiarity: a similar armature is present in

many Cantharide and Meloide.

9. Evalces dentipes.

Elongate, narrow, fusco-testaceous (the apical half of the elytra a little darker in one specimen), sparsely

pubescent, moderately shining. Head closely and rather coarsely punctured, the eyes black; antenne and

oral organs testaceous; prothorax not very convex, densely, finely, and somewhat roughly punctured, the

sides almost straight behind; elytra closely and finely punctured; beneath testaceous, the venter a little

darker ; legs moderately slender, pallid testaceous; anterior tibiz in the male armed on the inner side

with a sharp triangular tooth about the middle; central sheath of the cedeagus of the male slender, very

little curved, and furnished beneath with numerous bristly hairs.

Length (with the head extended) 8-3; millim. (¢ 9.)

Hab. Guatemaa, San Gerénimo, Paso Antonio (Champion).

Three examples, two males and one female, two of which were captured in the low

hot region of the Pacific slope. E. dentipes is closely allied to E. griseus, from which

it not only differs in its male characters, but in the finer and less rough punctuation of

the upper surface, and less convex thorax.

8. Evalces sinuatipes. (Tab. IV. fig. 24, ¢.)

Elongate, narrow, testaceous or fusco-testaceous, sparsely pubescent, slightly shining. Head densely and rather

coarsely punctured, the eyes black; antenne stout, testaceous; prothorax not very convex, somewhat

flattened on the disc, densely, finely, and rather roughly punctured, the sides straight behind ; elytra finely

and densely punctured; legs testaceous, comparatively stout; the anterior tibie slightly serrate within in

their apical half, and the posterior tibie sinuate, in the male.

Length (with the head extended) 34-33 millim. (¢ 2.)

Hab. GuaTeMALA, Chiacam and San Gerdnimo in Vera Paz (Champion); Panama,

Pena Blanca (Champion).

Four specimens, two of each sex. Rather more depressed than F. griseus; the

antenne and legs much stouter, the punctuation of the thorax and elytra finer, denser,

and less rough; and the hind femora distinctly sinuate in the male. ‘The anterior tarsi

are dilated in the male. The example from Chiacam, a female, has the thorax and

elytra more densely punctured, but it is apparently referable to the same species, the

sculpture also varying a little in the other specimens.

4. Evalces luteus.

Elongate, moderately narrow, luteous, sparsely pubescent, slightly shining; above finely and densely, the pro-

thorax more roughly, the head more coarsely, punctured. Antenne varying in colour from fusco-testaceous

to piceous with the two basal joints lighter; eyes black; prothorax large and convex, much rounded at

the sides, narrowing from the base; beneath densely and finely punctured ; legs ferruginous.

Length (with the head extended) 44 millim. ( 9.)

fab. Muxico, Acapulco (Hége), Omilteme in Guerrero 8000 feet, Cuernavaca (/. H.

Smith).

Three examples, apparently all females. The individual from Omilteme is of a

piceous-brown colour, but this is apparently due to discoloration. Much larger than

. griseus, the elytra more finely and more densely punctured, the thorax convex

and largely developed and with the sides much rounded.

5. Evalces longulus.

Elongate, narrow, fusco- or piceo-testaceous, sparsely pubescent, slightly shining; above very densely and

very finely, the head more coarsely, punctured. Antenne ferruginous; eyes black; prothorax not very

convex, the sides straight behind; elytra proportionately very long; legs ferruginous; beneath densely

punctured; central sheath of the cedeagus of the male slender and narrowing towards the end.

Length (with the head extended) 33 millim. (<¢.)

Hab. Mexico, Guanajuato (Sallé).

Two examples, one of which is a male. Narrower and smaller than £. luteus; the

thorax more finely and still more densely punctured and rather less convex. Larger

Six species of this sharply-defined genus have been described, four from Europe and

two from North America. We have now to record two from Guatemala, one from the

Atlantic, the other from the Pacific slope. The male of only one of these has been

discovered: this has the posterior femora not thickened, the posterior tibiz strongly

sinuate and with the inner apical angle not abruptly bent inwards and spiniform at the

tip, and the ventral segments 1-3 each furnished with a stout erect compressed tuber-

cular elevation, the insect thus differing greatly from the typical species of the genus.

The name Nothus having been thrice occupied in zoology, we do not follow Lacordaire

and others in using it.

The different species are found upon flowers.

1. Osphya tuberculiventris. (Tab. IV. figg. 25,4; 25a, profile of abdomen.)

Moderately elongate, rather narrow, the anterior half of the head, the oral organs, the prothorax above and

beneath, and the meso- and metasternum in the middle, testaceous or reddish-testaceous, the rest of the

upper and under surfaces black, the disc of the prothorax on each side longitudinally (or almost entirely)

and the head in front sometimes piceous or black, the surface slightly shining, somewhat thickly clothed

with short fine pubescence, the suture and two longitudinal stripes on each elytron (towards the side, the

outer one the broadest) clothed with ashy, the rest of the elytra with black, pubescence, the discoidal

stripes sometimes not defined or indistinct. Head very closely and finely punctured, the epistoma more _

sparsely and coarsely so; antenne slender, comparatively short, extending to about the basal third of the

elytra, piceous, the three basal and the three or four apical joints more or less testaceous; prothorax

transverse, the sides expanded, rounded posteriorly, and obliquely narrowing in front, the hind angles

obtuse, the base truncate but shallowly emarginate in the middle, the surface densely, minutely, and

uniformly punctured; elytra very densely and finely punctured, the punctures here and there confluent ;

beneath very closely and finely punctured, the ventral surface much more sparsely punctate towards the

apex; legs pubescent, piceous, the basal two-thirds of the femora and the basal half of the tibize more or

less testaceous.

3. Intermediate tibiz a little curved and at the apex slightly dilated within ; posterior femora not thickened, a

little curved ; posterior tibiz dilated in the middle and strongly sinuous within, their outer edge straighter ;

ventral segments 1-3 each with an erect flattened longitudinal elevation in the middle towards the apex

(fig. 25 a).

Length 6-6$ millim. (¢ 2.)

Hab. Guatemata, San Gerdnimo (Champion).

Six examples, four males and two females.

96 HETEROMERA.

2. Osphya pallida.

Moderately elongate, shining, sparsely pubescent, above and beneath and the legs and antenne testaceous or

yellowish-testaceous. Head finely and somewhat closely punctured; antenne (@ ) very long, extending

to far beyond the middle of the elytra; prothorax strongly transverse, the sides rounded, scarcely more

narrowed in front than behind, and very sharply margined, the margins reflexed, the base subtruncate but

shallowly emarginate in the middle, the surface finely and somewhat closely punctured, the punctures more

scattered on the disc; elytra more closely and roughly punctured than the prothorax; beneath closely

and finely punctured.

Length 54 millim. (9.)

Hab. Guatemata, Cerro Zunil, Pantaleon (Champion).

Two female examples. This species differs from O. tuberculiventris in its very much

longer antenne, shorter and more sharply margined thorax, and much coarser and

more diffuse punctuation of the upper surface. Both specimens are of a unicolorous

testaceous colour. O. lutea (Horn), from California, is apparently an allied species.

O. pallida has much the facies of the European Conopalpus testaceus, but is very much

smaller than that insect.

Ten species of this genus have been described, six from Europe or North Africa and

four from the United States; one is now added from Mexico. They are found upon

flowers in open places.

1. Mycterus depressus. (Tab. IV. fig. 26, 9.)

Elongate, depressed, rather narrow, piceous, the head in front and the oral organs reddish-testaceous, clothed with

very short ashy pubescence, slightly shining. Head densely and very rugosely punctured ; antenne (2 )

stout, rather short, extending a little beyond the base of the elytra, fusco-ferruginous, the three basal joints

and the apical one ferruginous, joint 3 nearly twice as long as 4, 4-10 decreasing in length but increasing

in width, 10 about as long as broad; prothorax narrow, subquadrate, broadest at the base and there very

much narrower than the elytra, a little broader than long, the sides feebly rounded and gradually narrowing

from the base, the disc canaliculate towards the base and apex and with a broad shallow oblique impression

on each side behind the middle, the impressions confluent at the base, the basal fovez distinct, the surface

densely and rugosely punctured (more finely so than the head); elytra parallel to about the middle, the

surface subcoriaceops, with widely scattered moderately coarse punctures arranged in very irregular rows,

the flat interspaces shallowly, minutely, and closely punctured, the apices slightly pointed; beneath very

densely punctured; legs entirely testaceous.

Length 6} millim.; breadth 2 millim. (9.)

Hab. Mexico, Villa Lerdo in Durango (Hége).

One female example. This species is allied to the North-American Jf. quadricollis,

Horn, an insect found upon the flowers of Agave in California and New Mexico; it

differs, however, in several particulars from the two published descriptions of M. guadri-

collis. MJ. depressus is more depressed than any other member of the genus known to

me; the male doubtless possesses differently formed antenne.

POLYPRIA. 97

The following genera are provisionally referred to the Melandryide. They are in

some respects intermediate between the Melandryide and the Pythide; but they do

not agree in several of their characters with either of these families as defined by

most authors. The coarsely granulated eyes, which are deeply emarginate in front

in Polypria and entire in the others, and immarginate thorax, the latter narrower than

the elytra, bring these genera near to some of the heterogeneous forms (Boros &c.) at

present included in the Pythide, from which they differ in the more or less broadly

lobed penultimate joint of the tarsi. Hurypus, Kirby, a genus overlooked by Lacor-

daire, is one of these intermediate forms; and Ischyomius, Chevr., would, as already

stated, doubtless, be better placed here.

POLYPRIA.

Polypria, Chevrolat, Rev. et Mag. Zool. 1874, p. 330.

This interesting genus contains a single species, and is apparently peculiar.to Central

America. Polypriawas referred by its describer to the Othniide, and stated to resemble

Derestenus, a genus of Cleride. It cannot be included in the Othniide owing to the

widely open anterior coxal cavities (not mentioned by Chevrolat) and other important

differences of structure. The genus seems best placed in the Melandryide. The

anterior coxe are contiguous; the eyes are exceedingly large, deeply emarginate in

front, and very coarsely granulated; the thorax is immarginate at the sides; the tarsi

are heteromerous (not five-jointed, as stated by Chevrolat), the outer joints broad and

lobed beneath, the penultimate one very broadly so, the claws appendiculate; and the

antenne with joints 4-10 strongly serrate. Polypria is closely allied to Hurypus,

Kirby, a heteromerous genus doubtfully included in the Cleride by Spinola*; in the

latter, however, the eyes are not emarginate in front.

1. Polypria crux-rufa. (Tab. V. figg. 1; la, labium; 16, maxilla and

maxillary palpus.)

the lateral margin, and more or less dilated at the base and apex, leaving two large

lateral spots flavous or fulvous, is described by Chevrolat as rufous: in our specimens

the spots are each surrounded by a rather broad piceous line, the space within the

piceous lines being rufous.

CONOMORPHUS.

Last joint of the maxillary palpi long, nearly twice as long as the third, moderately broad, subsecuriform, and

with its apical side about as long as the inner, and very much shorter than the outer side, that of

the labial palpi long, widening outwardly, and with its apex subtruncate ; mentum transverse, broadest

behind, the anterior angles somewhat obtuse ; maxilla with the inner lobe largely developed and broad ;

mandibles with the apex broad and feebly bifid; head large, slightly narrowed behind, the epistoma

not defined, the antennary orbits very little raised (more distinct in C. gracilicornis) ; eyes moderately

convex, rounded, entire, exceedingly large, and occupying the whole of the side of the head, narrowly or

widely separated above, much more distant beneath; antennw more or less slender, in some species

scarcely reaching the base of the prothorax, and in others extending beyond it, joint 3 twice as long

as 2, 4 shorter than 3, joints 4-10 usually decreasing in length and increasing in width (in some species

becoming triangular), each widening towards their apex, 11 ovate, somewhat pointed, and much longer

than 10; prothorax as long as or longer than broad, subquadrate, subcylindrical, usually a little

flattened on the disc, the sides immarginate or very obsoletely margined behind, the base feebly bisinuate

or nearly straight, and with more or less distinct fovex, the fovee connected by a basilar groove;

scutellum flat, transverse, or as long as broad; elytra exceedingly long, wider than the prothorax at the

base, usually widest at or beyond the middle, the humeri rounded ; anterior cox cylindrical, strongly

exserted, contiguous, the cavities open behind, but closed laterally ; mesosternum long, broadly and

largely extended anteriorly, and closing the anterior coxal cavities, the coxe rather narrowly separated,

the cavities closed; metasternum long, largely developed and convex, without median groove; posterior

coxse transverse, rather widely separated by the produced and acutely triangular intercoxal process ;

abdomen with five visible segments, the third and fourth with coriaceous hind margin ; legs moderately

long; the penultimate joint of all the tarsi broadly lobed beneath; tibial spurs small, the first joint of

the hind tarsi about as long as or rather longer than the following joints united; claws with the basal

half broadly and angularly dilated within; body very elongate, widest behind and subconical, or sub-

cylindrical, winged.

This genus so closely resembles Stilpnonotus (= Calophthalmus, Thoms.), that it is

with considerable hesitation I refer it to a different family, the open anterior coxal

cavities notwithstanding (not easily seen unless the prothorax is detached); the only

other apparent discrepancies between Conomorphus and Stilpnonotus being the more

slender antenne, more convex eyes, and flat scutellum, and in the thorax having more

or less distinct basal foveze, the latter connected by a basilar groove. The open

anterior coxal cavities being regarded by most authors as a character of paramount

importance for the purposes of classification, these genera are here referred to different

families: but at the same time it is necessary to call attention to these closely allied

forms, the one with open, the other with closed cavities. Conomorphus approaches

Eurypus in some of its characters, from which it differs in its more conical and more

cylindrical shape, more slender antenne, larger and less convex eyes, &c.; and in

general facies it somewhat resembles Boros, a genus of Pythide. I include in it three

species from Central America and two from Parana (one of which is described in a

CONOMORPHUS. 99

footnote on p. 100); and Calophthalmus tenuicornis, Fairm., from Minas Geraes,

doubtless belongs to the same genus. As in Stilpnonotus, a short space on either side

of the suture of the elytra near the apex is usually darker in colour, and the suture at

this part longitudinally impressed on each side. C. pilosus (from which the description

of the mouth-parts is taken) may be considered as the type of the genus. ‘The sexes do

not exhibit any external distinguishing characters.

Our specimens of C. pilosus and C. hrevicornis were beaten from the withered branches

of fallen trees.

1. Conomorphus pilosus. (Tab. V. figg. 2; 2a, labium; 26, maxilla and

maxillary palpus.)

Subcylindrical, narrowing anteriorly, piceo-castaneous, sometimes with a slight seneous lustre, moderately shining,

somewhat thickly clothed with rather long appressed hairs. Head very closely and rather coarsely punc-

tured; eyes black, widely separated; antenne slender, extending to a little beyond the base of the

prothorax, varying in colour from piceous to ferruginous, joints 4-10 subtriangular, decreasing in length

and increasing in width, but all much longer than broad, 11 ovate, and much longer than 10; prothorax

subquadrate, as long as broad, the sides immarginate, the disc a little depressed, more or less distinctly

canaliculate (more deeply so behind), and sometimes with a shallow oblique impression on each side

towards the base, the basal fovese deep, extending obliquely upwards for a short distance, and usually

connected by a shallow groove, the surface densely, subrugulosely, and somewhat coarsely punctured ;

scutellum flat, densely punctured; elytra gradually widening to about the middle and thence to the apex

converging, slightly depressed on each side within the humeri, the disc shallowly transversely impressed

some distance below the base, the suture for a short distance longitudinally impressed on each side near

the apex, a narrow space external to this more or less piceous in colour, the surface rather more finely

and much more sparsely punctured than the prothorax, more closely so towards the base, the posterior

half often with traces of very shallow longitudinal grooves; beneath shining, the ventral surface and

metasternum closely and finely punctured, the rest coarsely and densely so; legs more or less piceous, the

base of the femora and the basal half and the apex of the tibize often reddish.

Length 7-114 millim.

Hab. GuateMata, Cerro Zunil 4000 feet (Champion).

Six examples. This species is no doubt allied to Calophthalmus tenuicornis, Fairm.

2. Conomorphus brevicornis. (Tab. V. fig. 3.)

Subconical, fulvo-testaceous, the head and prothorax of a more ferruginous colour, the latter with the sides

broadly, and the elytra with a sinuous sublateral stripe, extending from the shoulder to about the middle

and there turning abruptly inwards and then again outwards, enclosing a triangular lateral patch (this

being flavous in colour in one example), and sometimes a common sutural patch just before the apex,

piceous or black, slightly shining, the surface clothed with short appressed pubescence. Head very closely

and finely punctured ; eyes black, rather widely separated; antenne yellow, short, scarcely reaching the

base of the prothorax, slender, widening outwardly, joints 4-10 gradually becoming more triangular in

shape, 7-10 very distinctly so, 9 and 10 as broad as long, 11 much longer than 10 and ovate; prothorax

cylindrical, subquadrate, as broad as long, the sides very feebly rounded or almost straight, and very

obsoletely margined behind, the disc longitudinally impressed in the middle behind and a little flattened,

the base with a well-defined groove connecting the short basal foves, the surface very densely and finely

punctured and subopaque ; elytra gradually widening to the middle and thence to the apex converging,

very closely and finely punctured throughout, the suture slightly depressed just before the apex; beneath

very closely punctured ; legs flavous or ferruginous.

8. Conomorphus gracilicornis. (Tab. V. fig. 4.)

Subcylindrical, narrow, scarcely wider behind, a little flattened above, castaneous, the prothorax and elytra

much stained with piceous, the suture of the latter with a common longitudinal black patch near the

apex, the surface sparsely pubescent and slightly shining, the prothorax opaque. Head very large, very

closely and not very finely punctured, the eyes black and rather narrowly separated, the palpi testaceous ;

antenne flavous, very slender, comparatively long, extending considerably beyond the base of the pro-

thorax, joints 4-10 all much longer than broad and each gradually widening towards their apex, 7-10

about equal in length, 11 ovate, very much longer than 10, and almost pointed; prothorax subquadrate,

as long as broad, the disc a little flattened and unimpressed, the sides immarginate, the base with a well-

defined groove connecting the short basal fovesx, the surface very densely and subrugulosely punctured ;

elytra subparallel, scarcely wider at the middle than at the base, very closely and finely punctured ; beneath

piceous.

Length 34 millim.

One example only. This small narrow species is somewhat doubtfully included in

Conomorphus; it agrees, however, in its chief characters with the other members of

the genus, from which it differs in its more parallel and more cylindrical shape, rather

larger head, more narrowly separated eyes, more prominent (but small) antennary

orbits, and longer and much more slender antenne.

CLEODAUS.

Very near Conomorphus and differing as follows :—The last joint of the maxillary palpi three times as long as

the third joint, subcultriform, its apical and outer sides about equal in length and each nearly twice as

long as the inner side, the inner angle rectangular; the last joint of the labial palpi rather large and

ovate, with the apex truncate, the second joint stout; head very broad, strongly narrowed behind, with

small but rather prominent antennary orbits; eyes very large, convex, not very coarsely granulated,

distant; antenne about reaching the base of the prothorax, joint 1 long and stout, 2 short and stout,

* Conomorphus flavicornis.

Subconical, fulvo-castaneous, the head and prothorax of a more ferruginous tint, the latter and the elytra each

with a black sublateral stripe, the stripe on the elytra extending to a little beyond the middle, and with

its outer edge interrupted posteriorly by an extension inwards of the ground-colour (this part flavous in

one example), the suture also marked with black or piceous near the apex, the surface sparsely pubescent

and moderately shining. Head very closely and rather coarsely punctured ; antenne as in C. brevicornis ;

prothorax longer than broad, the sides immarginate and almost straight, the surface densely and rugulosely

punctured, the disc very shallowly and obliquely impressed on each side behind, the base with a deep

groove connecting the short basal fovex; elytra transversely impressed on each side at the base, closely

and moderately finely punctured ; legs ferruginous.

3 longer and much more slender than 2, 4 shorter and a little wider than 3, 5 very much wider than 4,

5-10 very strongly transverse, angularly dilated within, and increasing in width outwardly, 7-10 nearly

twice as broad as long, 11 the width of and twice as long as 10; prothorax transverse, immarginate, with

distinct basal fovese ; scutellum strongly transverse; elytra very long, wider than the prothorax, widening

to the middle and then narrowing to the apex; anterior coxe contiguous, the cavities open behind ;

intermediate coxe very narrowly separated; legs rather short, moderately slender; claws towards the

base angularly dilated within ; body very elongate, widest behind, rather depressed above; the rest as in

Conomorphus.

This genus is proposed for a single species from the State of Panama. The long

and subcultriform apical joint of the maxillary palpi, differently formed antenne, and

short thorax readily distinguish Cleodwus from Conomorphus, to which it is closely

allied. The form of the antenne approaches that of Stilpnonotus and Eurypus, but in

both these genera joints 4-10 of the antennz are dilated within; in Cleodeus joints

5-10 only are widened, and 3 and 4 are more slender than 2 or 5. The head is more

narrowed behind than in Conomorphus.

1. Cleodzus rugiceps. (Tab. V. figg. 5; 5a, labium; 50, maxilla and maxil-

lary palpus. )

Piceous-black, sparsely clothed with brownish pubescence, slightly shining, the oral organs testaceous. Head

densely and coarsely punctured, transversely flattened between the eyes; antenne black, the basal joint

testaceous ; prothorax transverse, very little narrower at the apex than at the base, the sides slightly

arcuate in front and almost straight or very feebly sinuate behind, the hind angles acutely rectangular,

the disc with a large oblique rather shallow impression on each side about the middle, the base feebly

bisinuate, the surface densely and very minutely punctured (very much more finely so than the head);

scutellum densely punctured; elytra with traces of very shallow longitudinal grooves, densely, minutely,

and uniformly punctured; beneath closely punctured; legs (including the coxee) testaceous, the tarsi a

little darker in colour.

Length 442 millim.

Hab. Panama, Volcan de Chiriqui 3000 feet (Champion).

Two examples, agreeing exactly with each other. The head is very much more

coarsely punctured than the thorax or elytra and is transversely flattened or depressed

between the eyes, the latter being less coarsely granulated than in Conomorphus.

PHYSCIUS.

Last’ joint of the maxillary palpi broadly triangular, its apical side very little shorter than the outer and

about one third longer than the inner side, the inner angle subrectangular ; last joint of the labial palpi

rather slender, elongate-pyriform, the narrow end outwards; mentum strongly transverse; mandibles

entire at the apex; head inclined, large and broad, broader than the prothorax, narrowed behind,

less abruptly so in the female, the epistoma not defined, the antennary orbits very little raised; eyes

large, moderately convex, coarsely granulated, entire, occupying the whole of the side of the head, not

very widely separated in the male, more distant in the female; antenne slender, extending a little

beyond the base of the prothorax, joint 3 narrower and longer than 2, joints 4-10 angularly dilated

within, 6—10 transverse, 11 nearly twice as long as 10, ovate, and with the apex rather blunt; prothorax

transverse, immarginate at the sides, with distinct basal fovese; scutellum small; elytra moderately long,

much wider than the prothorax, widening from the base to far beyond the middle, very obtuse behind ;

anterior coxee contiguous, the cavities open behind but closed laterally; intermediate coxe very narrowly

separated, the cavities almost closed; metasternum convex ; legs slender, rather short, the tibial spurs

very small, the penultimate joint of all the tarsi lobed beneath; body subconical, moderately long, rather

convex, winged.

A single species from Central America is referred to this genus. Physcius is closely

allied to Cleodeus, but differs from it in the form of the maxillary and labial palpi and

also in that of the antenne. PP. conicus has much the facies of some of the more

elongate forms of Xylophilus, from which genus, apart from other characters, it may be

distinguished by the head not being sharply cut off behind. The antenne have joints

4-10 short and angularly dilated within. The chief character of the genus, however,

is the elongate-pyriform (almost subulate) apical joint of the labial palpi.

1. Physcius conicus. (Tab. V. figg. 6; 6a, labium; 64, maxilla and maxillary

palpus.)

Piceous-black or piceous, the sutural region of the elytra sometimes obscure castaneous, the surface clothed

with short ashy pubescence and slightly shining, the oral organs more or less testaceous. Head coarsely

and rather closely punctured; antenne yellow; prothorax transverse, as wide at the apex as at the base,

the sides very feebly rounded anteriorly and slightly sinuate behind or almost straight, the hind angles

rectangular, the disc with an oblique impression on each side about the middle, the impressions only

separated behind by an indistinct median ridge (more distinct in some examples than in others), the

surface closely and finely punctured; elytra closely and finely punctured and with traces of very shallow

longitudinal grooves, the suture slightly depressed before the apex ; beneath densely and finely punctured,

the metasternum more sparsely and more coarsely so; legs (including the coxe) yellow, the femora some-

times a little darker.

THISIAS.

Last joint of the maxillary palpi long and narrow, gradually widening outwardly, and very obliquely cut off

at the apex, the apical side about as long as the inner and not much more than half the length of the

outer side; last joint of the labial palpi cylindrical, the apex truncate ; mentum strongly transverse, the

sides rounded; ligula prominent, as broad in front as the mentum, its anterior margin broadly and

shallowly arcuate-emarginate; mandibles feebly cleft at the apex; head horizontal, scarcely narrowed

behind, the epistoma limited posteriorly by a shallow transverse groove and laterally by a deeper

longitudinal one, the antennary orbits not raised; eyes oblong, entire, lateral, moderately large, coarsely

granulated, feebly convex and not very prominent, and very widely separated above and beneath;

antenne short, not reaching the base of the prothorax, moderately stout, joint 3 more slender and

rather longer than 2, joints 4 and 5 subequal and each shorter than 3, 5 wider than 4, 6-10 the

broadest and angularly dilated within, all rather broader than long, 11 ovate and about twice as long as

10; prothorax transverse, with deep basal fovee, the sides immarginate; scutellum rather small; elytra

behind; anterior cox contiguous, the cavities open behind and closed laterally; intermediate coxe

narrowly separated, with distinct trochantin ; hind coxe transverse, rather widely separated by the broad

and acutely triangular intercoxal process; legs rather short, the tibial spurs very small, the penultimate

joint of all the tarsi broadly lobed beneath, the first joint of the hind tarsi not so long as the other joints

united, the claws towards the base angularly dilated within; body obovate, moderately elongate, a little

depressed above, winged.

This distinct genus includes a single species from Central America. It is not closely

allied to any other yet described, though approaching Hurypus in some of its characters.

Most of the specimens obtained of 7. marmoratus were found in forest-clearings,

about the withered branches of fallen trees or upon leaves.

1. Thisias marmoratus. (Tab. V. figg.7; 7a, labium; 76, maxilla and

maxillary palpus.)

Varying in colour from fulvo-testaceous to reddish-castaneous, the entire upper surface to a greater or less

extent irregularly spotted or marbled with piceous or black, slightly shining, and somewhat thickly

clothed with ashy or brownish pubescence. Head closely and not very finely punctured ; antennee flavous

or testaceous ; prothorax moderately transverse, rather wider at the base than at the apex (more distinctly

so in some examples than in others), the sides angularly dilated about the middle, the base very feebly

bisinuate, the disc with a more or less distinct oblique groove on each side about the middle and some-

times deeply longitudinally impressed in the middle at the base, the basal impression usually connected

with the deep fovex by a fine groove, the surface very closely and finely punctured; elytra with shallow

longitudinal grooves, punctured like the prothorax, the suture slightly depressed before the apex; beneath

castaneous or testaceous, more or less stained with piceous, very closely and finely punctured, the meta-

sternum more sparsely, the head and the flanks of the prothorax more coarsely and densely so; legs

testaceous, the femora sometimes a little darker.

Fam. PYTHIDZ.

This is a family of small extent, and, like the Melandryide, more numerously

represented in temperate than in tropical regions. From Central America we have to

enumerate seven species only, six of these being described as new. Homalirhinus,

Chevr. (=Rhinomalus, Gemm., = Xenorhinus, Lec. & Horn), species of which are not

uncommon in Central and South America, was referred to this family by Chevrolat (and

this position is adopted in Gemminger and Harold’s Catalogue) ; but this, as pointed out

by Leconte and Horn [Class. Col. N. Am. p. 134 (1883)], is a mistake, the genus, in

reality, belonging to the Cucujide. Cononotus may eventually be found to inhabit

North-west Mexico; the three species described are from California, and are said to

occur under stones. ‘The other members of this family are found under bark or about

the dead branches of trees.

Dr. Horn, who has kindly forwarded a specimen for comparison, informs me that he

has examples of this species from above Canada in the north to the lower U. S. border

in New Mexico, and that the insect probably follows the Sierra Madre southwards at a

high altitude (10,000 feet).

The fragmentary specimen forwarded by Mr. Flohr is 21 millim. in length.

SPITHOBATES.

Last joint of the maxillary palpi broad and securiform, that of the labial palpi cylindrical or narrowly ovate ;

inner lobe of the maxille furnished with a long sharp claw ; mandibles bifid, not or scarcely denticulate

within; mentum very broad and short, about two and a half times as broad as long, the front angles

rounded, the hind angles obtuse; ligula broad and very prominent ; head short, broad, rather convex,

the epistoma not defined, the sides of the front obliquely converging, the apex truncate, the labrum pro-

minent; eyes convex, entire, large or moderately large, coarsely granulated; antenne extending to a

little beyond the base of the prothorax, with the joints from the fifth broader than the preceding three,

or gradually widening outwardly and with joints 9-11 longer and wider than those preceding, the apical

joint elongate-ovate, the basal joint stout ; prothorax longer than broad, rather convex, strongly constricted

behind, much narrower at the base than at the apex, the sides (except at the base) more or less denticulate,

the base truncate and margined ; scutellum transverse ; elytra moderately long, wider than the prothorax,

parallel in their basal half and narrowing beyond, and with rows of punctures; anterior coxe contiguous ;

intermediate and hind coxe narrowly separated, the former without visible trochantin ; fifth ventral

segment as long as the fourth; legs moderately long, the femora rather stout, the tibiz with distinct

spurs, the penultimate joint of all the tarsi small and short, the first joint of the hind tarsi rather long ;

body convex, elongate, winged, sparsely clothed with decumbent hairs (which are serially arranged on the

elytra), the upper surface, legs, and antenne also with scattered, long, erect bristly hairs.

This genus is proposed to include two species from Central America. These differ

a little inter se in the form of the antenne and in the size of the eyes; but in other

SPITHOBATES. 105

respects, more especially in the structure of the mouth-parts, they agree well with each

other. Spithobates differs from Lissodema and Salpingus and their allies in the broad

apical joint of the maxillary palpi, convex and non-rostrate head (the epistoma con-

founded with the front), coarsely faceted eyes, &c., and also in its more elongate shape.

In both species the inner lobe of the maxille is furnished with a sharp claw; and the

upper surface of the body and the legs and antenne are clothed with very long, erect,

bristly hairs (which are easily rubbed off) in addition to the short decumbent pubescence.

The sides of the thorax are denticulate as in Lissodema, but more sharply so; the

last-mentioned genus does not appear to have been detected as yet in North America.

Upper surface unicolorous; antenne with joints 5-10 broader than those preceding

and subequal, 11 elongate-ovate ; eyes large.

1. Spithobates setosus. (Tab. V. figg. 8; 8a, labium; 8 6, maxilla and maxil-

lary palpus.)

Elongate, moderately convex, piceo-castaneous or castaneous, shining, sparsely clothed above and beneath

with ashy decumbent hairs, the upper surface and the legs and antenne also with scattered long, erect,

black, bristly hairs. Head somewhat thickly and rather coarsely punctured at the sides, sparsely so along

the middle; eyes large and coarsely faceted; antennz with joints 5-10 broader than 2-4, each widened

towards its apex and longer than broad, 11 ovate and nearly twice as long as 10, 5-11 more or less stained

with piceous, the rest ferruginous ; prothorax with five very prominent teeth on each side (the anterior

one forming the anterior angle the shortest, the hinder one placed at some distance before the base and

sometimes followed by a shallow oblique groove extending inwards), the apex (narrowly), the base (rather

broadly), and a longitudinal space down the middle of the disc smooth, the rest of the surface coarsely and

irregularly punctured, the punctures longitudinally or sinuously confluent ; scutellum densely punctured ;

elytra a little depressed below the scutellum and also with a shallow transverse depression on the middle

of each below the base, the basal portion with rather coarse punctures arranged in irregular rows, the

punctures thence to the apex very much finer and shallower; beneath thickly and somewhat coarsely

punctured, the metasternum very coarsely so at the sides; legs piceo-castaneous, the tarsi lighter, the

tibize curved a little outwards.

Length 32-5 millim.

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

Numerous examples.

Elytra spotted ; antenne with joints 9-11 longer and broader than those preceding ;

eyes smaller.

2. Spithobates maculatus. (Tab. V. fig. 9.)

Moderately elongate, convex, shining, piceous, the head and prothorax piceo-castaneous or castaneous, the elytra

each with a large spot before and another behind the middle, not reaching the suture, flavo-testaceous ;

sparsely clothed above and beneath with ashy decumbent hairs, the upper surface, legs, and antenne also

with scattered, long, black, erect, bristly hairs. Head coarsely and somewhat closely punctured; eyes

rather small ; antenne more or less ferruginous, joints 2-8 very gradually widening outwardly, 9 and 10

each much broader and longer than 8, 11 elongate-ovate and nearly twice as long as 10; prothorax with

four or five not very distinct teeth on each side, the hinder one usually the longest and often followed by

an oblique groove extending inwards, the surface coarsely, closely, and irregularly punctured, the punctures

longitudinally or sinuously confluent, a longitudinal space down the middle of the disc impunctate; scu-

tellum densely punctured ; elytra with rows of coarse punctures, the punctures becoming very much finer

on the apical third ; beneath closely and rather coarsely punctured ; legs more or less testaceous.

Length 23-32 millim.

Hab. Mexico, Jalapa, Cerro de Plumas (Hége).

Var. a. Head and prothorax usually of a more reddish tint; the latter with the punctures less confluent and

in some examples quite separate from each other; the elytra marked as in the type.

Hab. Guatemaua, San Juan in Vera Paz (Champion); Panama, Bugaba, Volcan de

Chiriqui (Champion). |

Var. b. The elytra with a narrow transverse flavo-testaceous band below the base (not reaching the suture),

the second spot not indicated ; the punctures on the prothorax more or less confluent, but not so coarse

as in the type; the legs rather darker, the femora in one example stained with piceous.

Hab. Guatemata, Cerro Zunil (Champion).

Numerous examples of the type and of the var. a, four only of the var. 6. In the

long series of specimens the extreme forms of this variable insect are connected by inter-

mediate examples; and they cannot be regarded as more than local races of one species.

The teeth at the side of the thorax are sharper in some examples than in others (but

they are never so strong as in S. setosus), the hinder one being sometimes very promi-

nent; occasionally they are in part obsolete. The punctures on the elytra are placed

in much more regular rows than in 9. setosus, and the rows are distinct to beyond the

middle. S&. maculatus is also much smaller and less elongate than S. setosus; it some-

what resembles Lissodema denticolle, Gyll., an insect inhabiting Northern Europe.

SOSTHENES.

Last joint of the maxillary palpi ovate, rather broad, obliquely truncated at the apex ; mandibles bifid; mentum

twice as broad as long; head very broad, short, rather convex, deeply sunk into the prothorax, not rostrate

in front, the epistoma very short and limited behind by a transverse groove, the labrum prominent; eyes

convex, prominent, rather large; antenne moderately stout, short, not reaching the base of the prothorax,

11-jointed—1 stout, ovate, 2 shorter and more slender than 1, 3 more slender and a little longer than 2,

obovate, 4-8 gradually decreasing in length and submoniliform, 9 nearly twice as wide as and much longer

than 8, transverse, 9-11 forming a moderately stout three-jointed club, 10 transverse, 11 ovate and longer

than 10; prothorax convex, very broad, transverse, narrower at the base than at the apex, the sides

immarginate, very strongly rounded, and constricted behind, the surface without depressions ; scutellum

very short, strongly transverse; elytra rather long, considerably wider than the prothorax at the base,

only a little wider than the latter in its broadest part, broadest about the middle, sparsely punctured ;

anterior coxe contiguous; intermediate and hind coxe moderately separated ; legs moderately stout, the

tibiee with distinct spurs, the penultimate joint of all the tarsi small; body winged, glabrous; form

elongate, subparallel, rather convex.

This genus contains a single species of small size from Guatemala.

Sosthenes is closely allied to Salpingus, but differs from it in the head and thorax

being broader; the head is shorter, non-rostrate in front, more convex behind, and

more deeply sunk into the thorax, the latter differently shaped; the elytra are only a

little wider than the widest part of the thorax; the eyes rather larger; and the

antenne shorter. A single example only having been captured, we have not ventured

to dissect the parts of the mouth.

1. Sosthenes dyschirioides. (Tab. V. fig. 10.)

1. Salpingus quichensis. (Tab. V. fig. 11.)

Dark brownish-bronze, shining. Head rather narrow, short, broadly and shallowly transversely impressed in

front, the epistoma broadly truncate, the surface coarsely and closely punctured ; antenne piceous, the

three basal joints ferruginous, joints 9-11 larger and wider than those preceding and forming a three-

jointed club; prothorax convex, narrow, the sides a little rounded anteriorly and constricted behind, the

disc with a very shallow oblique impression on each side about the middle, the surface closely and still

more coarsely punctured than the head; elytra very much wider than the prothorax, widest beyond the

middle, coarsely and irregularly striate-punctate, the punctures finer at the apex, the interstices flat, the

first with numerous, and the third, fifth, and seventh with a few finer impressions, the scutellar region

more irregularly punctured ; beneath and the oral organs and legs piceous, the extreme base of the tibie

and the tarsi lighter.

Hab. GuatemaLa, Quiche Mountains 8000 feet (Champzon).

A single example, found in the pine-forest region. S. guwichensis is, apparently, not

closely allied to any other species of the genus yet described. It has the head and

thorax comparatively narrow and closely and coarsely punctured, the punctures separate

one from another; the head is short and only slightly rostrate in front; and the antenne

have the apical three joints widened into a club.

LANTHANUS.

Last joint of the maxillary palpi subcylindrical, that of the labial palpi narrowly ovate; inner lobe of the

maxille longer and not narrower than the outer lobe ; mandibles bifid and with a short tooth before the

apex beneath, obsoletely denticulate within ; mentum strongly transverse, about twice as broad as long,

the apical angles broadly rounded, the hind angles rectangular ; ligula membranous and comparatively

small ; head wide, flattened and produced in front into a short broad beak, the labrum prominent; eyes

small, convex, very prominent; antennz reaching to a little beyond the base of the prothorax, inserted in

a cavity in the sides of the front, 11-jointed—1 small and very short (scarcely visible from above or

beneath), 2 large and ovate, more than twice as long as and very much stouter than 1, 3 as long as but much

more slender than 2, obovate, 4-8 decreasing in length and slightly increasing in width, 9 about three times

as wide and more than twice as long as 8, 9-11 forming a very large loosely-articulated three-jointed club,

11 broad ovate, a little longer than 10; prothorax transversely convex, broader than long, about as wide at

the base as at the apex, the sides very finely denticulate and somewhat rounded, the base and apex truncate,

the base narrowly grooved within on each side (the groove not always distinct), the disc (in one species)

with a deep oblique fovea on each side behind, the surface punctured; scutellum transversely triangular ;

elytra short and broad, convex, ovate, wider than the prothorax at the base, bluntly rounded at the apex,

smooth; anterior cox contiguous; intermediate coxe moderately separated; posterior coxe widely

separated; first ventral segment long, the intercoxal process broad, rounded in front; fifth segment short ;

legs slender, rather short, the tibie with distinct spurs, the penultimate joint of all the tarsi small; body

winged, very shining, clothed with a few scattered erect hairs; form oblong-ovate or obovate, convex.

Two small species from Central America are referred to this genus. One of these is

contained in the Sallé collection ; and it is labelled with the MS. name of Lanthanus

variegatus, Reiche, and placed in the Lathridiide. Lanthanus, however, has 5-, 5-, 4-

jointed tarsi, and is undoubtedly allied to Lvssodema, from which its more strongly

clubbed antenne, widely separated hind coxe, and other characters abundantly distin-

guish it. The antenne at first sight appear to be 10-jointed, the small basal joint being

partly hidden in a cavity in the sides of the front (and not easily seen unless the entire

organ is detached), and the second joint very large. The elytra are smooth and almost

destitute of sculpture (exceedingly minute scattered punctures only being visible under

a very strong lens). The thorax is thickly punctured ; and in one species has a very

deep fovea on each side of the disc behind, this being only feebly indicated in the other.

L. variegatus was found in abundance by myself in Guatemala, beneath the thin scaly

bark of old posts and in company with various subcortical Carabide and Histeride.

Lanthanus variegatus, Reiche, in coll. Sallé.

Oblong ovate, eneous or blackish-zneous, the front of the head of a more testaceous tint, the elytra each with

a transverse spot before and another behind the middle, not reaching the suture, pallid testaceous; very

shining, and clothed (especially on the prothorax) with fine scattered erect hairs. Head finely and somewhat

thickly punctured ; antennz with the basal joints testaceous, the rest piceous or black, in some examples

the club only black; prothorax strongly transverse, rather more coarsely punctured than the head,

and with a very deep oblique fovea on each side of the disc behind; scutellum with a few punctures ;

elytra smooth ; beneath varying in colour from piceous to piceo-testaceous, the metasternum, metasternal

side-pieces, and venter almost smooth, the rest thickly and rather coarsely punctured; legs testaceous, the

femora and tibie often more or less piceous.

Var. The entire upper surface of a brilliant eneous or golden-bronze tint; the elytra without spots.

Found in abundance at Zapote, sparingly elsewhere. The spotted and unicolorous

forms were collected together in about equal numbers at Zapote and also in British

Honduras. The Mexican examples are rather larger than the others. JL. variegatus

varies considerably in size, as well as in colour; the unicolorous variety is of a more

brilliant tint than the spotted form. One of the latter from Zapote is figured.

2. Lanthanus nitidus. (Tab. V. fig. 13.)

Obovate, golden-bronze, very shining. Head finely and somewhat thickly punctured ; antenne with joints 1-8

testaceous, the club piceous; prothorax moderately transverse, the basal groove deeply impressed laterally,

the disc with a very shallow almost obsolete oblique groove on each side behind, the surface sparsely and.

moderately coarsely punctured; elytra very much broader than the prothorax at the base, smooth ;

beneath piceo-seneous ; legs testaceous, the femora darker.

Length 2 millim.

Hab. Mexico, Cerro de Plumas (Hége).

One example only. This species is of more obovate shape than L. variegatus; the

thorax has the oblique fovea on each side of the disc barely indicated, and the basilar

groove more deeply impressed laterally ; and the elytra are relatively broader.

Fam. @DEMERIDA.

This is a family containing a large number of species in all parts of the World, and

most Oceanic islands possess one or more representatives. No systematic attempt has

hitherto been made to deal with the very numerous species inhabiting the warmer parts

of the globe, an immense number of which exist in collections, those of Europe and

North America only having been worked out as yet; and the comparatively few species

described from tropical regions have been in many cases erroneously referred to Kuropean

genera. A large number of species are now recorded from Central America, nearly all

of which are described as new; one only, and that an introduced one from Europe, has

hitherto been noticed from within the limits of our fauna. The inextricable confusion

existing at present amongst authors as regards the true limits of many genera, some

of which have not been really characterized*, has given me considerable trouble in

dealing with such a large amount of material. The form of the mandibles, which

ig not noticed by many authors, affords a good generic character In some cases;

while the clothing of the soles of the tarsi and the toothing or not of the claws often

cannot be depended upon. The false twelfth joint to the antenne in many genera is

characteristic of this family, it being really present in the males of some, e. g. Nacerdes

and Xanthochroa. No genus is known to me from Central America, except the intro-

duced Nacerdes, with a single spur to the front tibie. With some few exceptions,

the different species are apparently confined to a limited area, those frequenting the

sea-shore being rather more widely distributed. ‘The numerous representatives from

the Antilles, though closely allied in some cases, appear to be specifically different

from those from the mainland of America. Many of the Central-American forms

superficially resemble species of Telephoride. A considerable number of species

frequent the sea-shore in all parts of the World. |

We are much indebted to Dr. Horn for his assistance in communicating specimens

of many of the North-American species of this family ; and examples of all the North-

American genera and very many of the species have been examined; of the latter a few

are common to the Southern United States and Mexico.

CALOPUS.

Calopus, Fabricius, Syst. Ent. p. 182 (1775) ; Lacordaire, Gen. Col. v. p. 702.

Three species only of this genus have been described, one from Europe and two from

North America. Four are now added from Central America. The genus is remarkable

from having the antenne inserted in the canthus which extends partly across the eye.

The males of the Central-American species have the antenne subserrate and almost as

slender as in Sparedrus, and they thus differ considerably from the type. Calopus

much resembles some genera of Longicornia.

1. Calopus mixtus. (Tab. V. fig. 19, ¢.)

Very elongate, testaceous or piceo-testaceous, slightly shining, thickly clothed with ashy decumbent hairs, the

entire upper surface very closely and coarsely punctured. Head rather more sparsely punctured between

the eyes, the latter black and somewhat widely separated; antenne (d ) very long and slender, reaching

nearly or quite to the end of the elytra, joint 2 about one-third of the length of 3, the outer joints sub-

serrate ; prothorax about as long as broad, the sides rounded anteriorly and very gradually narrowing and

almost straight behind, the hind angles subrectangular, the disc somewhat flattened and with a shallow

oblique impression on each side and a transverse one before the base; elytra with numerous scattered,

smooth, irregular, slightly raised spots ; beneath very closely punctured ; the fifth ventral segment feebly

emarginate in the male.

Length 94-133 millim. (d.)

Hab. Guatema.a, Cerro Zunil 4000 to 5000 feet (Champion).

112 HETEROMERA.

Two examples, both males. In the smallest specimen the antenne extend fully to

the end of the body, but in the other and much larger one they are considerably

shorter. C. mixtus is closely allied to C. aspersus, Lec.; but differs from a Texan

specimen of that species before me in the more widely separated eyes and more slender

antennee in the male, the second joint of the latter being much longer (nearly twice as

long as in C. aspersus), the head and thorax not so closely punctured, and the elytra

with more numerous raised spots. The eyes are about as widely separated as in the

female of the European C. serraticornis.

2. Calopus obsoletus.

Closely allied to C. mixtus ; the prothorax more coarsely, the elytra less closely, punctured, the latter com-

paratively much less elongate and without smooth raised spots; the antenne ( ¢ ) extending to about two-

thirds of the length of the elytra and subserrate; the rest as in C. mixtus.

Length 11-113 millim. (¢.)

Hab. Guatemaa, Volcan de Atitlan 3000 feet (Champion).

Two male examples. C. obsoletus may prove to be only a local form of C. mirtus,

but it seems inadvisable to treat it as such, the two male specimens of each agreeing

well inter se. C. angustus, Lec., is an allied species, but differs in many important

particulars.

3. Calopus rugicollis.

Moderately elongate, comparatively convex, castaneous, slightly shining, sparsely pubescent. Head very coarsely

and closely punctured, the epistoma still more coarsely so, the eyes black and rather distant ; antenne ( 9 )

slender, reaching to the middle of the elytra, the outer joints moderately serrate ; prothorax convex, not

quite so long as broad, the sides rounded anteriorly and nearly straight behind, the disc with a short

shallow oblique impression on each side at the base only, the surface densely punctured, the punctures

very coarse but quite shallow and here and there confluent; elytra closely and coarsely punctured (the

punctures much finer and deeper than those on the prothorax), without traces of raised lines or spots, the

suture depressed below the scutellum and also for some distance before the apex ; beneath coarsely and

closely punctured.

Length 10 millim. (@.)

Hab. Guatemaa, El Jicaro in Vera Paz (Champion).

One example. This species is less elongate and more convex than the two preceding,

from both of which it differs in the very shallow, crowded, and coarser punctuation of

the thorax; the elytral punctuation is finer and rather more scattered than in

C. obsoletus.

4, Calopus depressus. (Tab. V. fig. 20, ¢.)

Very elongate, narrow, depressed, subparallel, testaceous, slightly shining, thickly pubescent. Head coarsely

and somewhat closely punctured, the eyes (3) black and rather distant ; antenne (¢ ) long and slender,

reaching to two-thirds of the length of the elytra, the outer joints subserrate ; prothorax about as long as

broad, widest a little before the apex and thence to the base very gradually narrowing, the hind angles

rectangular, the disc a little flattened behind and with a shallow arcuate impression just before the base,

the surface closely and rather coarsely punctured ; elytra depressed, very closely, shallowly, and moderately

CALOPUS.—MICROTONUS. 113

coarsely punctured; beneath finely and rather sparsely punctured ; legs slender; fifth ventral segment

feebly emarginate in the middle in the male.

Length 8 millim. (<¢.)

Hab. Mexico, near the city (Hoge).

One male example. Narrower, more depressed, more parallel, and much less coarsely

punctured than either of the preceding species, the thorax less rounded at the sides

anteriorly and broader in front, the legs more slender.

MICROTONUS.

Microtonus, Leconte, Class. Col. N. Am. p. 259 (1862); Leconte & Horn, Class. Col. N. Am.

pp. 404, 405 (1883).

This genus is referred by its author to the Gidemeride. Jtcrotonus has hitherto

only contained a single species from the United States; the six from Central America

here included in the genus differ considerably amongst themselves, and one or two of

them approach Symphora so closely that they might almost equally well be placed in

it. The typical representatives of Microtonus and Symphora have, it is true, a different

facies; but this is bridged over by the numerous additional species referred to these

genera in this work. ‘The structure of the maxillary palpi, antenne, legs, &c. seems to

be almost identical; and, apparently, the only difference of importance is the rather

longer mesosternum and more widely separated middle cox in Microtonus, the middle

coxee being about equally exserted in both. The thorax in both genera is without

distinct lateral suture, and it varies in shape in the different species—in typical

Microtonus it is subquadrate, sinuate behind, and with the hind angles acute, and in

Symphora short and subtrapezoidal; the transverse frontal suture of the head is also a

variable character, it being very distinct in some species and almost or quite obsolete in

others; the penultimate joint of the tarsi is feebly lobed beneath, and the basal joint

of the hind pair is very long in both. Microtonus would probably be better placed in

the Melandryide, after Symphora; but for the purposes of this work the position

assigned to it by Leconte is adopted for the present. Some of the Central-American

species referred to it (and to Symphora also) will no doubt have to be separated

eventually ; but with our wholly insufficient material it is inadvisable to propose new

genera for these intermediate forms.

The Central-American species may be separated thus :—

Body elongate or moderately elongate.

Eyes comparatively large, oblique; upper surface opaque, the pubescence

short and fine. |

Frontal suture distinct ; elytra spotted ; pubescence variegate . . jfiguratus.

Frontal suture indistinct ; elytra unicolorous; pubescence uniform. gracilis.

Pubescence longer and coarser; sides of the thorax converging from the

base, the hind angles acute and extending outwards. . . . . fusiformis.

1. Microtonus figuratus. (Tab. V. fig. 14, 2.)

Moderately elongate, comparatively broad, opaque ; brownish-black, the head and the sides and base of the pro-

thorax (broadly) reddish, the elytra each with a large transverse brownish-testaceous patch (angulate on

its lower edge and with a branch extending upwards) below the base, not quite reaching the suture and

enclosing an oblong spot, and an oblique stripe beyond the middle, this stripe confluent with the opposite

one at the suture, extending along the latter towards the apex, and in front connected with the transverse

patch ; the entire upper surface very densely and uniformly punctured and clothed with short ashy pubes-

cence, the elytra bare in places and with the pubescence assuming the form of stripes or spots. Head

with well-defined transverse frontal suture, the eyes comparatively large, the antenne and palpi testaceous ;

prothorax transverse, unimpressed, the sides converging from the base, rounded in front, and sinuate

behind, the hind angles acute; elytra comparatively broad, rather short; beneath piceous, densely and

somewhat coarsely punctured and pubescent ; legs piceous-brown, the tarsi testaceous, the first joint of

the hind tarsi longer than the following joints united.

Length 33 millim. (¢.)

Hab. Mexico, Jalapa (Hége).

One male example. This elegantly-marked little insect closely agrees with M. sericans,

Lec., in its general structure ; but differs in the thorax being less quadrate, and in the

elytra being comparatively broader and spotted and with the pubescence variegate. At

first sight, the pubescence appears to be abraded; but this is not the case, the arrange-

ment being exactly similar on each elytron. The punctuation of the elytra is very dense

and regular, and the minute interspaces have a somewhat granular appearance ; the

markings are difficult to describe and they will be best understood from our figure.

2. Microtonus gracilis. (Tab. V. fig. 15, 2.)

Elongate, narrow, convex, opaque, piceous-brown, the head reddish, the entire upper surface densely and

coarsely punctured, the head and prothorax rugosely so, and clothed with short silky pubescence. Head

with the transverse frontal suture shallow, the epistoma short, the eyes comparatively large and more

widely separated in the female than in the male, the antenne and palpi testaceous ; prothorax transverse,

narrowing from the base, the sides feebly sinuate behind and rounded in front, the hind angles acute, the

surface quite unimpressed; elytra less rugosely punctured than the head and prothorax and not so dull ;

beneath piceous, densely and coarsely punctured and pubescent ; legs very slender, testaceous, the femora

a little darker, the first joint of the hind tarsi much longer than the following joints united ; sixth ventral

segment in the male furnished on each side with a long spatulate appendage.

Length 23-22 millim. (¢ 2.)

Hab. Guatema.a, San Gerénimo 3000 feet (Champion).

MICROTONUS. 115

Two specimens. This species is allied to M. sericans, Lec., from which it differs in

its narrower shape, much more coarsely punctured surface, shallow frontal groove, and

unimpressed and differently-shaped thorax.

3. Microtonus pilosus.

Elongate, rather narrow, convex, subopaque, dull brown, the head reddish, the entire upper surface densely

and somewhat roughly punctured and clothed with rather long appressed ashy pubescence. Head with

the transverse frontal suture shallow, the apical joint of the maxillary palpi piceous; eyes small, very

widely separated, black; antenne piceo-testaceous, joints 2 and 3 testaceous; prothorax transverse,

unimpressed, very little narrowed anteriorly, the sides rounded in front and sinuate behind, the hind

angles acute; elytra comparatively elongate; beneath piceous, densely and coarsely punctured and

pubescent ; legs testaceous, the femora and the apices of the tibie piceous, the first joint of the hind tarsi

very little longer than the following joints united.

Length 33 millim.

Hab. GuatTeMALA, Quiche Mountains 8000 feet (Champion).

One specimen, apparently a female. This species differs from M. gracilis and

M. sericans in its very much smaller, more transverse, and more widely separated eyes,

and much longer pubescence; the thorax is less narrowed in front than in M. gracilis

(thus resembling J. sericans), and the first joint of the hind tarsi is shorter.

4, Microtonus nitidulus. (Tab. V. fig. 16.)

Elongate, shining, piceous or brownish-piceous, the entire upper surface thickly and rather coarsely punctured

and sparsely clothed with long appressed ashy pubescence. Head without distinct transverse frontal

suture, the eyes small and very widely separated in both sexes, the palpi and antennez piceous; prothorax

transverse, narrowed in front, the sides rounded anteriorly and strongly sinuate behind, the hind angles

acute, the surface not so closely punctured as that of the head, an ill-defined longitudinal space on the middle

of the disc impunctate ; elytra very long, each with a large shallow oblique impression below the base and

a much shallower oblong one near the suture about the middle (the latter sometimes indistinct), the

punctures more scattered than on the prothorax and becoming a little finer and shallower towards the apex ;

beneath closely punctured and pubescent; legs very long, piceous, the basal two-thirds of the tibie and

the first joint of the hind tarsi more or less testaceous, the latter as long as the following joints united.

Length 32-53 millim. (¢ 9.)

Hab. Guatemata, Totonicapam 9000 to 10,000 feet (Champion).

Four examples. This insect differs from the type of the genus, M/. sericans, in the

smaller and more transverse eyes, impressed elytra, shining and more sparsely punctured

surface, coarser pubescence, longer legs, and almost obsolete frontal suture. J. pilosus

is, however, intermediate between the two.

5. Microtonus elongatus. (Tab. V. fig. 17, ¢.)

Very elongate, narrow, subfusiform, subopaque ; varying in colour from testaceous with the head and prothorax

reddish and the elytral suture a little darker, to piceous with a testaceous stripe on each elytron extending

from the shoulder to the apex; the entire upper surface densely and coarsely (the head and prothorax

rugosely) punctured, and clothed with fine, short, appressed pubescence. Head without distinct transverse

frontal suture, the eyes moderately large, smaller and more distant in the female, the antenne varying

in colour from piceo-testaceous to testaceous ; prothorax convex, almost as long as broad, the sides nearly

straight behind and converging in front, the hind angles subrectangular, the surface unimpressed ; elytra

very elongate, the punctures separate one from another, and not confluent as on the head and prothorax ;

beneath piceo-testaceous or piceous-brown, closely and coarsely punctured and pubescent ; legs very long,

more or less testaceous, with the femora and the apices of the tibie stained with piceous, the first joint of

the hind tarsi rather longer than the following joints united.

Length 33-43 millim. (¢ 9.)

Hab. Mexico, Real del Monte in Hidalgo (Hége).

Five specimens. Larger and very much more elongate than Jf. sericans and

M. gracilis. The general outline more fusiform, the thorax longer, the frontal suture

obliterated. Our two male examples exhibit the above-described dark coloration,

the three females being of a much lighter tint; the males are considerably narrower

than the females.

6. Microtonus fusiformis. (Tab. V. fig. 18.)

Very elongate, fusiform, convex, slightly shining; the head and prothorax reddish-testaceous, the latter much

suffused with piceous; the elytra testaceous, with a large triangular scutellar patch, the suture narrowly,

but with a common oblong patch beyond the middle and another at the apex, and an oblong lateral patch

about the middle (extending narrowly upwards and downwards along the margin), piceous ; the entire

upper surface densely and coarsely (the head and prothorax rugosely) punctured, and clothed with long

appressed pubescence. Head without distinct transverse frontal suture; eyes moderately large, not very

convex, black; antenne and palpi testaceous; prothorax convex, not so long as broad, the sides rapidly

~ and obliquely converging from the base, the hind angles very acute and extending outwards as far as the

base of the elytra, the surface unimpressed ; elytra very elongate, more shining than the prothorax, the

punctures moderately close ; beneath piceous, the venter and metasternum in great part reddish-testaceous,

closely and coarsely punctured and pubescent; legs very long, testaceous, the basal joint of the hind tarsi

much longer than the following joints united.

Length 5 millim.

Hab. GuatEMA.a, Calderas 6000 feet (Champion).

At first sight, IZ. fusiformis appears to be only a colour-variety of MZ. elongatus; it

is, however, more convex, broader, and more fusiform; the thorax is differently-shaped,

the hind angles being very acute and extending outwards as far as the shoulders of the

elytra, and the sides rapidly converging from the base; the punctuation of the elytra

is more diffuse; the first joint of the hind tarsi is more elongate; and the pubescence

is much longer and coarser. The two examples obtained agree precisely in colour;

they are apparently both of the male sex.

NACERDES.—DITYLUS. 117

Nacerdes, like Xanthochroa, has twelve-jointed antenne in the male, a single spur to

the anterior tibia, and bifid mandibles. We have only to notice a single species from

our region, and this an introduced one from Europe, which seems to be rapidly

extending to various parts of North and Central America. This species, V. melanura

(Linn.), though a common insect on the sea-shore, where it breeds in old posts &c., is

frequently found inland; it has no doubt been transmitted in timber.

Leconte & Horn, Class. Col. N. Am. p. 404 (1883).

Mimetes, Eschscholtz, Mém. Ac. Petr. vi. p. 468 (1818).

Species of this genus have been described from Europe, East Africa, Madagascar,

North America, and the Canary, Salvages, and Cape Verd Islands. Six are here

enumerated from Central America, one from Mexico and five from the Los Altos

region of Guatemala; several of these differ widely from the known species of the

genus in the enormously enlarged head in fully-developed males, this development

being also present to a less degree in the female. Every degree of development is

present in the Central-American species, from that of the European D. levis (Fabr.),

in which the head is not at all dilated behind the eyes, to one in which the head in

the male is almost as large in proportion as it is in the same sex of the genus Horia.

In the lowest development of the.female of D. meaxicanus the head is formed as in

D. levis and various North-American forms; in most of our examples of the various

species, however, not only of the male but of the female also, the head is more or less

dilated at the sides behind the eyes, and in this respect the Central-American repre-

sentatives of the genus apparently differ from all others yet described.

In these latter the antenne are stout in both sexes, and about reach the middle of

the elytra (in the females of D. brachinoides and D. cephalotes they are shorter); the

eyes are small and distant from the point of insertion of the antenne, finely granulated,

rather transverse, and usually prominent; the mandibles are bifid; the joints 1-4 or

2-4 of the front tarsi, 1-4, 2-4, or 3 and 4 of the middle tarsi, and 3 of the hind tarsi

are spongy-pubescent beneath; the tibial spurs are long; and the claws are simple.

The three insular species described by Wollaston have larger, more depressed, and

118 HETEROMERA.

much more coarsely granulated eyes; and they will probably have to be separated

from Ditylus.

* Head largely developed in both sexes, in some species enormously large in the male.

1. Ditylus brachinoides. (Tab. V. fig. 21, 2.)

Elongate, rather convex, finely pubescent, varying in colour from brownish-ochraceous to ferruginous, the head

usually with a piceous patch in the middle below the eyes, the elytra often darker, and sometimes of a

blackish-brown tint, the prothorax shining, the head subopaque, the elytra very opaque. Head densely

and very finely punctured, with a smooth raised line on the vertex behind—in small males and in the female

moderately dilated behind the eyes, and as wide as the prothorax, in fully-developed males enormously

large, much wider than the prothorax, with the sides largely and obliquely dilated behind the eyes, and

extending laterally far beyond them, and abruptly constricted behind, and the mandibles also greatly

elongated,—the eyes black, quite small, and not prominent; antenne varying in colour from testaceous to

fusco-ferruginous ; prothorax about as long as broad, the sides much rounded anteriorly and strongly

constricted behind, the hind angles acute, very broadly transversely depressed in front, and deeply

impressed in the middle before the base, the disc usually with a shallow depression on each side about

the middle, the surface very minutely, closely, and irregularly punctured (more sparsely so than that of

the head), a very narrow longitudinal space down the centre, raised in the middle or in front, and deeply

impressed behind, impunctate, the apex emarginate in the middle in fully-developed males; elytra

moderately long, a little convex, rather narrow at the base and widening to far beyond the middle,

somewhat obtuse behind, very finely, closely, and shallowly punctured, with two rather broad vague coste

down the middle of the disc and one near the sides, extending from the base nearly to the apex, the suture

also a little raised; beneath rather dull, finely and densely punctured and pubescent, reddish-ochraceous

or ferruginous, sometimes stained with piceous; legs more or less ochraceous or ferruginous, very stout in

fully-developed males ; fifth ventral segment arcuate-emarginate in the middle in both sexes.

Length 83-15 millim. (¢ 9.)

Hab. Mexico, Jacale, Orizaba (Sal/é).

Numerous examples. This fine species is labelled D. brachynoides, Chevr., in the

Sallé collection. The head in fully-developed males is enormously enlarged; males

of minor development and females approach D. mexicanus &c. in this respect. The

species is exceedingly variable in size and colour, and also in the degree of development

of the head in the male. Examples of it from Mexico are also contained in the National

and other collections. D. brachinoides, as its name suggests, has much the facies of a

Brachinus.

A fully-developed male is figured.

2. Ditylus longicollis. (Tab. V. fig. 22, 4.)

Moderately elongate, rather convex, finely pubescent, above and beneath and the legs and antennz unicolorous

brownish-ochraceous, the head and prothorax slightly shining, the elytra opaque. Head closely and

minutely punctured, dilated behind the eyes, as wide as the prothorax—in well-developed males broader

than the prothorax and much larger,—the eyes black, quite small, and not prominent; prothorax longer

than broad, convex, the sides rounded in front and moderately constricted behind, the hind angles acute,

the disc deeply impressed in the middle before the base, and with one or two vague impressions on each side

anteriorly, the surface rather more finely and sparsely punctured than that of the head, a narrow longitudinal

space down the middle of the disc impunctate; elytra comparatively short, rather convex, widest about

the middle, very shallowly, minutely, and closely punctured, and with one or two very vague cost on the

DITYLUS. 119

middle of the disc (distinct only towards the base), and (in one example) with a more distinct one near

the side extending from the shoulder to beyond the middle, the suture also a little raised; beneath finely

and densely punctured and pubescent; fifth ventral segment broadly and shallowly arcuate-emarginate.

Length 7-84 millim. (¢.)

Hab. Guatema.a, Tepan 6000 feet (Conradt).

Two male examples. Closely allied to D. brachinoides, and differing as follows :—

The head more sparsely and finely punctured, not so dull, and without a smooth raised

line on the vertex; the thorax longer and more convex, the surface more even and

without distinct transverse depression in front; the elytra shorter, widest about the

middle, and with the vague costz on the disc almost obsolete.

3. Ditylus cephalotes, (Tab. V. fig. 23, 2 .)

Elongate, rather convex, finely pubescent; varying in colour from dark piceous-brown to ferruginous with

the prothorax testaceous, the latter in dark examples often more or less reddish or fulvous at the sides

anteriorly, and the shoulders also lighter in colour; the head slightly shining, the prothorax shining, the

elytra opaque. Head densely and finely punctured, and with a narrow smooth longitudinal space (slightly

impressed in some examples) on the middle of the vertex, dilated at the sides behind the eyes, and largely

developed in both sexes, broader than the prothorax in the male, the eyes convex and prominent, the

antenne stout; prothorax longer than broad in the male, broader and rather shorter in the female,

convex, the sides very much rounded anteriorly and strongly constricted behind, the hind angles

moderately prominent, the disc transversely depressed before the middle and also before the base, and

with an oblique impression on each side in front, the surface very closely and finely punctured, a smooth

narrow longitudinal space on the middle of the disc impunctate, this space more or less impressed towards

the base, the base finely margined (the margin not raised); elytra coriaceous, moderately long, widest

beyond the middle, very closely and minutely punctured, with two very vague coste on the middle of the

disc, these only distinct towards the base, and obsolete beyond, the suture also a little raised towards the

base; beneath and the legs coloured like the rest of the body, the former finely and densely punctured

and pubescent; fifth ventral segment unemarginate in the middle in both sexes.

Length 84-11 millim. (¢ 2.)

Hab. Guatemaa, Totonicapam 8500 to 10,600 feet (Champion).

Eleven examples, found beneath loose pine-bark. To judge from this series there is

very little sexual disparity in the development of the head in D. cephalotes; in the male

the thorax is rather narrower and longer than it is in the female, and the head, in con-

sequence, appears to be broader. More elongate than J. longicollis; the eyes much

more prominent and a little larger; the head more densely punctured; the thorax

more strongly rounded at the sides anteriorly, and more constricted behind. The

more evenly convex thorax, prominent eyes, &c., distinguish it from D. brachinoides

in all its varieties.

4, Ditylus tepanensis.

Elongate, rather convex, finely pubescent, piceous-brown; the head opaque, castaneous at the sides and in

front, the epistoma and mandibles testaceous, the latter with the tips black; the prothorax shining,

and with a reddish vitta on each side and an oblong spot on the middle of the disc behind; the

elytra slightly shining. Head finely and not closely punctured (the punctures closer at the base and

more distant in front), with a smooth impressed line on the middle of the vertex, moderately dilated at

120 HETEROMERA.

the sides behind the eyes, and largely developed, as wide as the prothorax, the eyes quite small and not

prominent, the antenne ferruginous and stout; prothorax longer than broad, convex, the sides much

rounded in front and moderately constricted behind, the hind angles very prominent, the base strongly

margined, the disc transversely depressed before the middle and also before the base, the surface irregularly

and rather sparsely punctured, a smooth, narrow, longitudinal space on the middle of the disc impunctate,

this space deeply impressed towards the base; elytra coriaceous, long, widest beyond the middle, depressed

on each side at the base in the centre, closely, shallowly, and finely punctured, with three vague coste

and several very irregular shallow longitudinal grooves extending from the base nearly to the apex, the

suture also a little raised; beneath finely and closely punctured and pubescent; legs fusco-ferruginous ;

fifth ventral segment unemarginate.

Length 143 millim. (2.)

Hab. Guarema.a, Tepan 6000 feet (Conradt).

One example. Larger and broader than the largest examples of the corresponding

sex of D. cephalotes ; the head and thorax much less closely punctured, the latter with

the base more strongly margined and the hind angles more extended; the eyes not so

prominent; the elytra more shining, more strongly (though very shallowly) punctured,

and with shallow longitudinal grooves and vague coste extending from the base nearly

to the apex.

** Head largely developed in the male (at least in D. mexicanus), normal

in the lowest development of the female.

5. Ditylus mexicanus. (Tab. V. fig. 24, 3.)

Elongate, depressed, finely pubescent, blackish-violaceous; the head and prothorax violaceous or bluish, and

slightly shining, the latter with a red spot on each side in front, or with the sides rather broadly, and the

disc also red; the elytra very opaque. Head as wide as the prothorax, a little dilated on each side behind

the eyes—in well-developed males longer and broader, with the sides behind the eyes more extended

(reaching outwardly as far as the eye itself), and more abruptly narrowed behind,—very finely and densely

punctured, the eyes small, the antenne black; prothorax about as long as broad, the sides strongly

rounded anteriorly and much constricted behind, the hind angles acute, the disc with a deep (or shallow)

transverse depression in the middle before the base, a shallow one in front, and two more or less distinct

rounded depressions on each side (one before, the other behind the middle), the surface densely, finely, and

irregularly punctured, the punctures in the depressions obliquely confluent, an irregular, narrow, longi-

tudinal, slightly raised space on the middle of the disc impunctate; elytra moderately long, subparallel in

their basal half, broadly flattened on the disc, very minutely and densely punctured, the punctures

connected by oblique scratches, with one or two vague coste down the middle of the disc, and one near

the side (the latter extending from below the shoulder to the apex, and limiting the flattened portion

laterally), the suture also a little raised; beneath finely and densely punctured and pubescent, violaceous,

the prothorax and venter sometimes reddish ; legs black; fifth ventral segment arcuate-emarginate in the

middle in the male, rounded in the female.

Length 73-103 millim. (¢ 2.)

Hab. Mexico (Sallé), near the city (Hoge).

Five examples, two males and three females. This species is distinguished by its

depressed form from all others of the genus yet described. The elytra, when viewed

under a strong lens, are obliquely strigose. D. meaicanus is apparently allied to

D. bicolor and D. cyanipennis, Horn.

DITYLUS.—DIPLECTRUS. . 121

- finely and densely punctured and pubescent; legs piceous ; fifth ventral segment truncate.

Length 8? millim. ( 9.)

Hab. Guatemana, Tepan 6000 feet (Conradt).

One female example. Narrower, less parallel, and more convex than D. meaicanus ;

the eyes more prominent; the thorax shorter, more minutely punctured, more shining,

and differently coloured; the elytra with exceedingly minute punctures, the punctures

not connected by oblique strige.

DIPLECTRUS.

Diplectrus, Kirsch, Berl. ent. Zeitschr. xxx. p. 210 (1866).

This genus was proposed by Kirsch for a single species, D. ferrugineus, from Colombia,

of which he had, apparently, only the female before him. Several other species from

Central America are here referred to it, and @demera (Nacerdes) marginata, Guér.,

from Colombia, and various undescribed forms from Tropical South America are, no

doubt, congeneric with them. Our species are of large size and elongate-parallel

shape, and they agree in the following particulars: —Antenne 11-jointed in both sexes ;

apical joint of the maxillary palpi elongate-triangular or cultriform, with the apex very

obliquely rounded or truncate, that of the labial palpi more or less securiform ;

mandibles bifid* ; eyes rather finely granulated, feebly emarginate, moderately large,

transverse when viewed from above; prothorax as long as or longer than broad, -

rounded at the sides in front, constricted behind, and with prominent hind angles ;

elytra very long, more or less parallel; anterior tibiee with two spurs; tarsi with all

the joints, except the apical one, densely tomentose beneath; claws feebly dilated at

the base. Male with the ‘fifth ventral segment more or less emarginate in the

middle; the sixth segment visible through the emargination of the fifth, or extending

a little beyond it, divided down the middle, and with the dorsal and ventral portions

about equally developed; the sheath of the cedeagus with an accompanying, separate,

spoon-shaped piece (the lateral ldbe of an additional segment f) on each side. Female

with the fifth ventral segment feebly emarginate or rounded.

* The form of the mandibles is not stated by Kirsch.

+ In the Cistelide the corresponding spoon-shaped piece forms part of the sixth ventral segment; in

Diplectrus it is part of an additional, or seventh, segment.

122 HETEROMERA.

In the males of some of the Central-American species the anterior, or the anterior

and intermediate, tibiee are furnished with a smooth triangular projection at their inner

apical angles, and the intermediate or the four hinder tibie are dilated within; in one

of these species all the femora are also much thickened.

* Upper surface entirely opaque.

1. Femora thickened, the anterior tibie with a smooth angular projection at their inner

apical angle, and the four hinder tibie dilated towards the apex, in the male.

1. Diplectrus nigripes. (Tab. VI. figg. 1,3; la, cedeagus.)

Elongate, parallel, opaque, densely and finely pubescent, yellowish-ochraceous ; the head and legs black or

piceous; the prothorax sometimes of an orange tint, and in rare individuals stained with piceous on

each side (in one example the piceous colour is much extended, and the base, apex, and a line down

the middle alone remain of the ground-colour); the elytra with the extreme base and the apical half or

less black (sometimes with the black portion less extended, and in the form of a very large oblong patch),

or entirely yellowish-ochraceous. Head densely and finely punctured, the eyes prominent and rather large ;

antenne black or piceous, sometimes with the outer joints ferruginous (joints 3-5 pale at the base in one

example), very long and slender, tapering outwardly, joint 2 one-third of the length of 3, 3 longer than 4;

prothorax convex, about as long as or rather longer than broad, strongly rounded at the sides in front and

much narrowed behind, the base with distinct margin, the hind angles prominent, the disc feebly trans-

versely depressed in the middle before the base, the surface punctured like that of the head; elytra long

and parallel, about one and a half times the width of the prothorax, a little flattened on the disc, finely and

densely punctured, sometimes with traces of one or two very faint coste on the disc, the apices separately

rounded; beneath very densely punctured, thickly clothed with long ashy pubescence, more or less piceous,

the prothorax and venter ochraceous; legs densely punctured and pubescent, the four hinder tibie a little

curved.

3. Femora very stout; anterior tibie slightly constricted on the inner side immediately before the apex, and

smooth and shining at this part, the inner angles strongly and triangularly produced ; intermediate tibie

dilated within on the inner side towards the apex ; hind tibie sinuously curved and strongly and abruptly

dilated within towards the apex ; fifth ventral segment slightly emarginate in the centre; sixth ventral

segment divided down the middle; the central sheath with an accompanying, separate, spoon-shaped piece

on each side, the latter fringed with long hairs at the apex.

Length 143-184 millim. (¢ 2.)

Hab. Nicaraceva (Sallé), Chontales (Belt, Janson).

This remarkable insect is not uncommon at Chontales, and is contained in many

collections. The amount of black on the apical portion of the elytra varies very much

in the numerous examples before me, and in about one-third of them it is altogether

obsolete; the head and legs, however, and the antenne in great part, are constantly

black or piceous. The male may be readily distinguished from the allied forms by the

thickened femora, dilated hinder tibiz, and peculiar form of the inner apical angles of

the anterior tibie. D. nigripes has very much the facies of certain Central-American

species of the Malacoderm-genus Chauliognathus.

DIPLECTRUS. 133

2. Femora slender, the anterior and intermediate tiliw with a smooth, sharp, angular

projection at their inner apical angle, and the latter dilated towards the apex, in

the male.

2. Diplectrus armatus.

a more rufous tint. Head very closely and finely punctured, the tips of the mandibles and the eyes

black, the latter large (antenne missing); prothorax rather longer than broad, not very convex, the sides

moderately rounded in front and converging behind, the hind angles prominent, the disc somewhat

flattened, obsoletely longitudinally depressed on each side, and with a transverse deeper depression in the

middle before the base, the surface punctured like that of the head; elytra very long, parallel, one and a

half times the width of the prothorax, minutely and densely punctured, and with two vague cost on the

dise and one close to the lateral margin (the inner one extending to about the middle and the others nearly

to the apex), the suture also a little raised, the apices separately rounded ; beneath coloured as above,

very densely punctured, and finely pubescent; legs very long, testaceous, the tibize and tarsi and the

apices of the femora piceous.

3. Anterior tibie armed at the inner apical angle with a smooth, sharp, triangular projection ; intermediate

tibie a little curved, widened within from the middle, and becoming still broader outwardly, the inner apical

angle produced into a smooth, short, triangular projection ; posterior tibie simple; fifth ventral segment

very deeply and rather narrowly emarginate in the middle (the emargination extending nearly halfway

across it) ; sixth ventral segment divided down the middle, and only visible through the emargination of the

fifth ; the central sheath with an accompanying, separate, largely-developed spoon-shaped piece on each side.

Length i9 millim. (¢.)

Hab. Nicaraeua, Chontales (Belt).

One male example, Much more elongate than D. nigripes, the elytra narrower and

proportionately very much longer; the eyes large; the thorax less convex, not so

strongly rounded at the sides in front; the elytra with more distinct coste; the

pubescence of the under surface shorter and finer. The male characters are totally

different :—-In the present species the femora are not thickened; the intermediate as

well as the front tibiee have a sharp projection at the apex; the intermediate tibie are

very much dilated towards the apex, the posterior pair being normal; and the fifth

ventral segment has a large and deep emargination.

The femora are not stouter than in the female of D. nigripes. |

3. Femora slender, the tibie without angular projection at their inner apical angle, and

not dilated (at least in D. annulicornis), in the male.

3. Diplectrus annulicornis. (Tab. VI. fig. 2, ¢.)

Elongate, subparallel, densely and finely pubescent, opaque, unicolorous, brownish-yellow or brownish-

ochraceous. Head closely and not very finely punctured, with traces of a smooth central line, the eyes

black. or piceous and moderately large, the maxillary palpi and the tips of the mandibles much stained

with piceous; antenne black or piceous, the base of each joint flavous or testaceous, moderately long,

tapering outwardly, joint 2 not half the length of 3, 3 a little longer than 4; prothorax rather longer than

broad, narrow, the sides rounded anteriorly and converging behind, the base and apex rather strongly

margined, the hind angles prominent, the disc a little flattened, shallowly transversely depressed in front

and more deeply so behind, and with traces of a smooth median line or ridge, the surface densely and

the sixth ventral segment divided down the middle; the central sheath with a separate, small, accompany-

ing spoon-shaped piece on each side.

Length 133-16 milliim. (¢ 9.)

Hab. Mexico (Flohr), Cordova (Sallé), Jalapa (Hoge); GuatTemaLa, Cerro Zunil

(Champion); Costa Rica, Volcan de Irazu, Rio Sucio (Rogers).

Many specimens. Smaller and less elongate than D. giganteus; the elytra much

shorter in proportion, narrower, and with the apices separately rounded; the antenne

differently coloured, and with less elongate joints, 3-5 being much shorter; the thorax

shorter, less compressed at the sides, and more finely punctured ; the legs less elongate ;

the fifth ventral segment emarginate in the middle in both sexes. In the male of

D. annulicornis the head is a little broader than in the female; and the fifth ventral

segment is as deeply emarginate as in D. armatus, but still more broadly so. A male

specimen from Cerro Zunil is figured.

According to Mr. Flohr, D. annulicornis is not uncommon in the temperate and

colder regions of Mexico.

4, Diplectrus giganteus. (Tab. VI. fig. 3, 2.) |

Very elongate, subparallel, opaque, ochraceo-ferruginous, the head and prothorax of a more rufous tint, densely

longer, depressed in front, and more densely and more finely punctured, the punctuation

becoming scabrous in places; the elytra relatively broader, with the apices rounded

‘ together (not separately and with the sutural angle rounded as in D. armatus), and of

a browner tint.

DIPLECTRUS, 125

5. Diplectrus concolor.

Very elongate, parallel, opaque, above and beneath and the legs and palpi yellowish-brown, densely clothed

very densely punctured, pubescent ; legs very long; fifth ventral segment (2) shallowly emarginate.

Length 20 millim. ( 9.)

Hab. Panama, Volcan de Chiriqui 4000 feet (Champion).

One specimen. Closely allied to D. giganteus and differing thus:—The head more

densely punctured; the thorax shorter, more rounded at the sides in front, flatter on

the disc, and less compressed at the sides; the elytra rather narrower, and with the

apices separately rounded ; the fifth ventral segment ( ? ) shallowly emarginate in the

middle; the legs, antenne, and palpi entirely testaceous; the upper surface of a more

luteous tint.

** Head and prothorax shining, the elytra opaque; femora and tibie slender

in the male.

6. Diplectrus nitidicollis, (Tab. VI. figg. 4,3; 4a, labium; 46, maxilla and

maxillary palpus; 4c, cedeagus.)

Elongate, parallel, finely pubescent, the head and prothorax shining, the elytra opaque, above and beneath and

the legs and palpi ferruginous. Head closely and moderately finely punctured, with traces of a shallow

transverse depression between the eyes, the latter ( $ ) black, convex, prominent, rather small, and widely

separated, the tips of the mandibles piceous; antenne moderately long, comparatively stout, joint 2 more

than half the length of 3, 3 and 4 equal; prothorax about as long as broad, moderately convex, the base

and apex slightly emarginate in the middle, the former with prominent margin, the sides strongly rounded

in front and converging behind, the hind angles prominent, the disc on each side transversely depressed

just before the apex, irregularly and obliquely depressed about the middle, and canaliculate in the centre

at the base (in one example canaliculate to the apex, in the other with a smooth central ridge in front),

in the middle; elytra long, about one and a half times as broad as the prothorax, very closely and finely

punctured, with three rather broad vague coste on the disc and one close to the lateral margin (the first

and third extending to about two-thirds of the elytral length and not raised, the others nearly reaching

the apex), the suture also a little raised, the apices separately rounded; beneath pubescent, densely

punctured ; legs moderately long, the hind tibie (¢) feebly sinuate; fifth ventral segment ( ¢) broadly

and deeply emarginate, the sixth divided down the middle, the central sheath with an accompanying,

separate, small spoon-shaped piece on each side. .

Length 16-19 millim. (¢.)

Hab. Costa Rica, Rio Sucio (Rogers).

_.Two male examples. This species agrees very nearly with the description of

126 HETEROMERA.

D. ferrugineus, Kirsch, from Bogota; it differs, however, in its entirely ferruginous legs

and antenne and other particulars. The shorter and stouter antenne, shining thorax,

less elongate elytra, and smaller and more convex eyes distinguish it from D. concolor.

DIPLECTROIDES.

Mandibles narrowing to the apex, the apex not cleft; last joint of the maxillary palpi long, elongate-

triangular, the apical side only about half the length of the inner side, the apex obliquely rounded

off, that of the labial palpi of somewhat similar shape; eyes finely granulated, convex, very large,

still larger and more approximate in the male (smaller and more distant in D. flavicollis, 2 ), feebly

emarginate ; antenne 11-jointed in both sexes, exceedingly elongate in the male, reaching nearly to the

apex of the elytra, shorter in the female, joint 2 very short, one-third or one-fourth the length of 3, 3

and 4 subequal, 11 slightly constricted beyond the middle (giving the appearance of a twelfth joint),

prothorax much as in Diplectrus (shorter in D. flavicollis, 2); elytra very elongate, broadest at the base,

the sides rectilinear or nearly so and gradually converging to the apex, the dise with very vague coste or

rows of double lines ; legs very long; anterior tibie with two spurs; tarsi with all the joints except the

apical one clothed with a dense brush of short hairs beneath; claws feebly dilated at the base; the rest as

in Diplectrus. Male with the fifth ventral segment deeply triangularly emarginate; the ventral portion

of the sixth segment very largely developed, furnished with two very large, long, spoon-shaped pieces

‘(placed one above the other in repose, resembling two additional segments) which extend far beyond the

fifth segment, the dorsal portion of the sixth short and without lateral appendages.

A single species from Mexico and Guatemala is referred to this genus, and a second,

from Mexico, of which female examples only have been received as yet, is also provi-

sionally included in it. Both are of large size and resemble the larger species of the

Malacoderm-genus Chauliognathus inhabiting the same region. ‘The above characters

are chiefly taken from D. longicornis. In the male of this latter the antenne are

exceedingly elongate; the eyes are very large and separated by quite a narrow space

above; the ventral portion of the sixth segment is very largely developed (the dorsal

portion being quite short), and the two, long, broad, spoon-shaped pieces with which it

is furnished lie one above the other in repose and extend far beyond the deeply emar-

ginate fifth segment (in Diplectrus the sixth segment is often only visible through

the emargination of the fifth, and though divided down the middle it lies quite flat in

repose), the sheath of the cedeagus being, apparently, unaccompanied by an additional,

separate, spoon-shaped piece on each side. In both sexes of D. longicornis the elytra

(when closed along the suture) are distinctly broadest at the base, and very gradually

and rectilinearly narrowed to the apex.

1. Diplectroides longicornis. (Jab. VI. figg. 5,¢; 5a, labium; 54, maxilla

and maxillary palpus; 5c, cedeagus.)

Very elongate, yellowish-brown, with the prothorax, the head in front, and the scutellum of a more flavous or

orange tint, and the head between and behind the eyes and the base of the elytra faintly suffused with viola-

ceous or bluish-violaceous; the head in some examples entirely of the latter colour; the elytra sometimes

with the apex as well as the base very distinctly marked with violaceous or bluish-violaceous, and the rest of

the surface often faintly suffused with violaceous or purplish, in one example entirely violaceous with the

base and extreme apex bluish; the upper surface very densely clothed with short ashy pubescence, and

DIPLECTROIDES.—VASACES. 127

opaque, the head and prothorax not so dull. Head (including the eyes) about as wide as the prothorax

in the female, broader in the male, densely and rather coarsely punctured, longitudinally depressed

between the eyes; the latter black, exceedingly large and narrowly separated in the male, smaller and

more distant in the female; antenne very long in both sexes, still longer in the male, black or blackish-

brown; prothorax about as long as broad, the sides moderately rounded in front and converging behind,

the base and apex somewhat strongly margined, the former indistinctly emarginate in the middle, the

hind angles prominent, the disc with a large triangular or V-shaped depression in front, irregularly trans-

versely depressed behind, and often with a smooth median ridge or channel, the surface finely and densely

punctured (in some examples less closely so); elytra very elongate, very densely and minutely punctured,

the apices separately rounded ; beneath very densely punctured, thickly pubescent, testaceous, the venter,

and sometimes the coxe, more or less suffused with violaceous; legs blackish-violaceous, the femora often

in great part testaceous.

3. Fifth ventral segment very deeply triangularly emarginate; the sixth with two very large spoon-shaped

pieces, these latter hairy within.

Length 13-19 millim. (¢ 9.)

flab. Mexico, Misantla (Hége); Guatemaza, Sinanja, Sabo, Purula, and San Geré-

nimo in Vera Paz (Champion), Vera Paz (Conradt).

Ten male and three female examples; the single specimen ( 2 ) from Mexico has

the head and elytra violaceous. The localities for this species are all upon the Atlantic

slope.

Our figure is taken from a typical male specimen from Sinanja.

2. Diplectroides flavicollis. (Tab. VI. fig. 6, 2.)

Elongate, black or brownish-black, the head and scutellum brownish in one example, the prothorax flavous’

the upper surface finely pubescent, the head and prothorax shining, the elytra opaque. Head very finely

and closely punctured, the eyes ( 2 ) moderately large and rather widely separated ; antenne ( 9 ) blackish-

brown or brown, moderately long ; prothorax ( 2 ) rather broader than long, moderately rounded at the sides

in front and constricted behind, the base and apex somewhat strongly margined, the hind angles promi-

nent, the disc a little flattened, transversely depressed on each side in front and also about the middle,

depressed in the centre at the base, and with traces of a smooth median ridge, the surface very minutely,

shallowly, and closely punctured ; elytra shorter than in D. longicornis, scabrous, the apices obtuse ; beneath,

the prothorax excepted, black or brownish, pubescent, finely scabrous ; legs black or brownish.

Length 143-163 millim. (9).

Hab. Mexico, Peras, Parada (Sallé).

Two female examples. Differs from the corresponding sex of D. longicornis in the

smaller and more widely separated eyes, much more finely punctured head and thorax,

the latter broader than long, shorter and stouter antennex, shorter and more scabrous

elytra, shorter legs, and different colour.

VASACES.

Mandibles bifid; last joint of the maxillary palpi long, elongate-triangular (V. wneipennis, V. sordidus) or

cultriform with the outer edge sinuate (V. costatus), that of the labial palpi subtriangular; mentum

about twice as broad as long; eyes somewhat coarsely granulated, rather small, oblique, very widely sepa-

rated in both sexes, rather distant from the point of insertion of the antenne, and, at most, very slightly

emarginate ; head about as broad as the prothorax, a little broader in the male, rather produced in front ;

antenne filiform, long, slender, 11-jointed in both sexes—1 stout or moderately stout, about as long as 3,

2 about half the length of 3 (in V. sordidus, 2 , nearly as long as it), 3 shorter than 4, the succeeding

128 HETEROMERA.

joints very elongate, 11 slightly emarginate at the middle; prothorax subquadrate, at least as wide at the

base as at the apex, the sides a little rounded in front and, at most, moderately constricted behind ; elytra

considerably broader than the prothorax, elongate and parallel, with regular raised lines or coste ; legs very

long and slender, the tibiz each with two rather long spurs; joints 1-4 of the anterior and intermediate

and 3 of the posterior tarsi, more or less (V. eneipennis), or the penultimate one only of all the tarsi

(V. sordidus and V. costatus), spongy-tomentose beneath; claws simple. Male with the fifth ventral

segment very deeply triangularly emarginate; the ventral portion of the sixth segment with a spatuli-

form lobe on each side which extends beyond the fifth segment (this being very long in V. enetpennis

and short in V. costatus), the dorsal portion furnished on each side with a quite slender and very much

shorter lobe, each of the lobes fringed with long hairs at the apex.

Closely allied to and of the general form of Xanthochroa; but differing in the

anterior tibie having two spurs, and in the antenne being 11-jointed in both sexes,

and with joint 2 more elongate, at least half the length of 3, the latter shorter than 4.

The three species from Central America referred to Vasaces have somewhat the

facies of a female of the genus Dryops, from which they differ in the more transverse

eyes, more quadrate thorax, longer tibial spurs, much longer second joint of the

antennee, broader apical joint of the maxillary palpi, &c.

Species of Xanthochroa have been recorded from the United States and from Colombia,

as well as from Europe and Japan, and Lacordaire states (Gen. Col. v. p. 705) that

numerous others from South America exist in collections; no species of Gidemeridee

from Central America described in this work agrees sufficiently well with Xanthochroa

to be included in it, and it is very possible that the South-American forms are not

really congeneric.

* Apical joint of the maxillary palpi elongate-triangular.

1. Vasaces xneipennis. (Tab. VI. fige. 7, ¢; 7a, labium; 70, maxilla and

maxillary palpus; 7 c, cedeagus.)

Very elongate, finely pubescent, slightly shining, testaceous or reddish-testaceous, the head in the middle, the

eyes, the tips of the mandibles, and the disc and sides of the prothorax more or less piceous, the scutellum

or rather longer than broad, moderately constricted behind (less distinctly so in one specimen), the base and

apex with prominent margin and very feebly emarginate in the middle, the disc deeply transversely

depressed in front and behind, with a rather deep sinuous groove on each side, and more or less canali-

culate, or with a slightly raised median ridge, in the centre, the surface very finely and densely punctured,

/more sparsely so on the disc; elytra very elongate, densely and finely punctured, the punctures more or

‘less confluent, each with four distinct raised lines or cost extending from the base nearly to the apex,

the suture also a little raised, the apices separately rounded; beneath densely and minutely punctured,

finely pubescent, testaceous, the metasternum and venter (and in one example the prothorax) stained with

piceous or obscure zneous; legs entirely testaceous; fifth ventral segment emarginate in the middle in

both sexes.

and moderately finely punctured, slightly infuscate on the middle of the vertex, the tips of the mandibles

and the eyes black, the latter feebly sinuate on their inner edge; antenne ( ? ) elongate, slender, reaching

to beyond the middle of the elytra, testaceous, the basal half of each joint darker, joints 1 and 3 about

equal in length, 1 slender, 2 a little shorter than 3, 3 a little shorter than 4, 11 feebly sinuate at the

middle and somewhat pointed at the apex; prothorax longer than broad, the sides feebly emarginate

behind and a little rounded anteriorly, the disc with a sinuous groove on each side, a short longitudinal

groove in the middle in front, and a transverse depression just before the base, the basal margin a little

raised, the surface thickly, finely, and very distinctly punctured; elytra moderately long, somewhat

attenuate at the apex, shallowly, densely, and finely punctured, each with four distinct raised lines or

costee extending from the base nearly to the apex, the suture also raised, the cost~@ and suture each with

an indistinct interrupted row of fine oblong fuscous streaks on either side; beneath testaceous; legs very

slender, pallid testaceous, the knees, the apices of the tibie, and the tarsi a little darker.

Length 83 millim. ( 9.)

Hab. Guatemata, Capetillo (Champion).

One immature female example. Smaller than V. costatus; the head and thorax

more coarsely, the elytra much more shallowly and less densely punctured, the latter

more acuminate behind and of the same colour as the thorax. ‘The last joint of the

maxillary palpi is also very differently shaped, it being triangular and formed very much

punctured, and with a feeble transverse elevation on each side between the points of insertion of the

antennee, the tips of the mandibles and the eyes black, the latter merely sinuate on their inner edge;

antenne (¢) exceedingly elongate and slender, nearly reaching the apex of the elytra, fusco-testaceous,

the. basal joint and the apices of the others testaceous, joint 1 stout, 1 and 3 about equal in length,

moderately elongate, very densely and finely punctured (the punctures more or less confluent), each with

four distinct raised lines or costa extending from the base nearly to the apex, the suture also a little

raised, the apices separately rounded and obtuse; beneath very closely and finely punctured, finely

pubescent, testaceous, the flanks of the prothorax, the metasternum, and venter much suffused with

piceo-seneous ; legs testaceous, the tarsi a little darker.

130 HETEROMERA.

Hab. Guatemata, Cerro Zunil 4000 feet (Champion).

One male example. Much smaller than V. eneipennis; the eyes almost entire; the

elytra less elongate; the antenne longer and more slender ; the tarsi more slender; the

sixth ventral segment and last joint of the maxillary palpi differently shaped.

SISENES.

Mandibles bifid ; last joint of the maxillary palpi long and narrow, narrowly ovate or widening a little out-

wardly, with the apex very oblique and truncate or somewhat rounded, that of the labial palpi subtri-

angular, with the apex more or less truncate or rounded; eyes finely granulated, more or less prominent—

larger, more transverse, more convex, and more deeply emarginate in S. cyanipennis and S. boops, more

oblong, moderate or small, and feebly emarginate in the other species; head as broad as or broader than,

and not deeply sunk into, the prothorax, a little prolonged in front, the mandibles long and exposed and

the labrum large; antenne 11-jointed in both sexes, tapering a little outwardly, filiform, or with joints

3-5 thickened in the female or in both sexes, the eleventh joint often a little constricted beyond the

middle; prothorax about as long as broad with the sides moderately constricted behind, or subquadrate

with the sides almost straight behind, at least as broad at the base as at the apex, the disc usually with

one or two transverse grooves or depressions on each side; elytra long or moderately long, subparallel—in

some few species flatter and in one or both sexes widening to beyond the middle,—with series of double

lines or fine cost; legs moderately long, stout in a few species (S. cyanipennis &c.), slender in others ;

femora similar in both sexes; tibiee each with two long spurs; tarsi in some species with joints 1-4 or 2-4

of the front and middle pairs and 2 and 3 or 3 of the hind pair, or in others with the penultimate joint only,

furnished with a brush of short hairs beneath; claws very feebly dilated at the base within. Male with

the fifth ventral segment in some species deeply, in others feebly, emarginate in the middle; sixth ventral

segment with long or short lateral lobes, these often projecting beyond the fifth segment.

Numerous species from Central America are referred to this genus, and it will

in all probability prove to be equally well represented in South America. The

narrower and differently shaped apical joint of the maxillary palpi and _ other

particulars distinguish it from Diplectrus, Vasaces, Copidita, Asclera, &c.; the

eleven-jointed antenne in the male and the two-spurred anterior tibize separate it

from Nacerdes and Xanthochroa; and the finely granulated and rather prominent

eyes, bifid mandibles, narrow apical joint of the maxillary palpi, and more quadrate

thorax distinguish it from Oxacis.

Several groups of species are indicated, these differing from one another in the form

of the antenne, extent of emargination and form of the eye, and in the clothing of the

soles of the tarsi; but as they are connected by various gradations it is not advisable to

separate them. The different species vary in size, but are mostly small; the majority

have much the facies of various genera of Telephoride, and in these species the antenne

taper very slightly or are more or less filiform, while a few resemble Lycide, these

latter having joints 8-5 of the antenne thickened or dilated. One, S. lineatocollis, has

these joints thickened in the female only. In S. cyanipennis the tarsi are formed and

clothed somewhat as in Diplectrus (from which the narrower last joint of the maxillary

palpi and different male-characters distinguish it); S. boops and S. varians are inter-

SISENES. 31

mediate in this respect between S. cyanipennis and the numerous species with the

penultimate joint only of the tarsi tomentose beneath.

The Lyciform species have the antenne formed very much as in the Chilian genus

Mecopselaphus ; the latter, however, has a Lampyriform facies (it was included in the

Malacoderms by its describer), the head more exserted and longer, and the thorax

very differently shaped ;. Mecopselaphus lycoides, Kirsch, from Peru, is, no doubt, con-

generic with these aberrant mimetic forms.

The members of this genus are all well defined, though in several the elytra vary

very considerably in colour. They are found upon leaves or herbage.

Seven examples. This very distinct species somewhat resembles Diplectroides flavi-

collis, from which its less elongate shape, more coarsely punctured head and prothorax,

shorter and stouter limbs, and violaceous colour distinguish it, apart from the differences

in the form of the mandibles, palpi, &c; the sixth ventral segment of the male is

very similarly shaped.

Length 9-10 millim. (¢ 2.)

Hab. Nicaraeva, Chontales (Belt).

One male and five female examples. The thorax, elytra, and under surface vary in

the extent of the dark markings, while the head is constant in colour in all the forms ;

the elytra have at least the apex piceous or black. In the example with dark elytra

the thorax is wholly reddish-yellow.

Fifteen examples, three from Mexico, the rest from Guatemala; of these, four, one

from Chacoj and three from Cordova (one of which is figured), have a well-defined pale

flavous longitudinal vitta on each elytron, and the apex of the femora more distinctly

marked with piceous, the Mexican specimens having the ground-colour of the elytra

short, hairy, and projecting beyond the fifth.

Length 53-7 millim. (¢ 9.)

Hab. GuaTEMALA, Purula and Sinanja in Vera Paz (Champion).

This insect has much the general facies of the Malacoderm-genus Parasilis, two

species of which inhabit Central America. SS. parasiloides is closely allied to S. suffusus,

but is smaller and differently coloured ; the head and thorax are not so densely punc-

tured and are less opaque, the oblique depression on each side of the disc of the latter

being much shallower; the antenne are more slender ; and the sixth ventral segment

of the male is very differently shaped.

Numerous examples, all captured in the humid forest-region of the ‘Aviantic slope.

elevated transverse space before the middle seneous, and the sides flavous at the base, or testaceous with the

disc greenish-seneous ; the elytra bluish-black with the disc dark brown, or brown with an seneous lustre,

and with a narrow sordid yellow stripe extending from the shoulders nearly to the apex, and the suture

also a little lighter in colour. Head very closely and finely punctured, the eyes oblong and rather large

but not prominent ; antennz piceous or fusco-testaceous, very long, slender, and filiform, extending nearly

to the end of the elytra in both sexes, joint 2 one-third of the length of 3, the succeeding joints very

_ elongate ; prothorax a little longer than broad, the sides moderately rounded in front and converging behind,

the base grooved within and the margin prominent, the disc shallowly transversely depressed in front, with

a deep oblique depression on each side behind the middle, and a more or less distinct median ridge, the

surface very closely and finely punctured; elytra long, parallel, densely and rather coarsely punctured,

and with two fine coste on the disc and one at the sides, the two outer ones nearly reaching the apex and

enclosing the yellowish vitta and the inner one extending to a little beyond the middle, the suture also

raised ; beneath closely punctured and thickly clothed with long ashy pubescence, fusco-testaceous, the

metasternum and the venter stained with eneous; legs slender, piceous, the base of the femora and of

the tibie lighter, the penultimate joint of the tarsi tomentose beneath.

3. Fifth ventral segment very deeply emarginate; the sixth with the lateral lobes long and spoon-shaped

and protruding beyond the fifth.

Length 73-83 millim. (¢ 2.)

Hab. Nicaraeva, Chontales (Belt); Panama, Volcan de Chiriqui 3000 feet (Champion).

A male from Nicaragua and a female from Chiriqui. From the striped form of

S. sugfusus this species may be distinguished by the closer and finer punctuation of the

head and thorax; the elytral vitta is narrower, placed nearer the lateral margin, and

extends upwards to the shoulder; the legs are darker, the eyes larger and more oblong,

the antenne longer, the under surface duller and more pubescent, and the fifth ventral

segment in the male more deeply emarginate.

The Chiriqui specimen is figured.

7. Sisenes rubricollis. (Tab. VI. fig. 15, 3.)

Elongate, finely and thickly pubescent, opaque, the elytra and the greater part of the head black or piceous-

brown, the latter with the anterior part (the labrum and the tips of the mandibles excepted) flavous and

the posterior part sometimes of a more eeneous tint, the prothorax dull red or rosy-red. Head very

densely and moderately finely punctured, the eyes rather small but prominent, the palpi fusco-testaceous ;

antennee long and filiform, about reaching the middle of the elytra in the female, longer in the male,

joint 2 rather more than one-third of the length of 3, black, the two basal joints sometimes testaceous

beneath ; prothorax about as long as broad, the sides moderately rounded in front and a little constricted

behind, the base grooved within and with rather prominent margin, the disc shallowly transversely

depressed in front, with a rather deep oblique depression on each side behind the middle, and a more or

less distinct median ridge, the surface very densely and moderately finely punctured ; elytra long, more

parallel in the male than in the female, densely and somewhat roughly punctured, and with two fine

costee on the disc and one at the sides, the two outer ones nearly reaching the apex and the inner one

extending to a little beyond the middle, the suture also raised ; beneath slightly shining, thickly pubes-

cent, variable in colour—usually flavo-testaceous with the metasternum and the sides of the venter piceous

or eneo-piceous, sometimes in great part piceous, the lower part of the flanks of the prothorax violaceous

and smooth, the rest of the surface closely and finely punctured ; legs slender, varying in colour from

piceous to fusco-testaceous, the penultimate joint of the tarsi tomentose beneath, the hind tibis in some

examples slightly curved or sinuous.

shaped and protruding beyond the fifth.

Length 63-83 millim. (¢ 2.)

Hab. Mexico, Cordova’ (Sallé), Jalapa, Oaxaca (Hoge), Atoyac in Vera Cruz (Schu-

mann). . .

This species is apparently common on the Atlantic slope of Southern Mexico, whence

we have received many specimens. S. rubricollis is allied to S. suffusus, from which its

more densely and less coarsely punctured head and thorax, duller and more closely and

more distinctly punctured under surface, more deeply emarginate fifth ventral segment

in the male, and more opaque and differently coloured upper surface distinguish it

at once. The specimens in the Sallé collection are labelled with the inapplicable MS.

Closely allied to S. rubricollis; the elytra variable in colour—bluish-black, blackish-brown, or brownish-

yellow; the head greenish-szneous or brownish, with the anterior part (the labrum and the tips of the

mandibles excepted, these parts being piceous) flavous; the antenne black, very long and slender, reaching

to far beyond the middle of the elytra in both sexes; the prothorax rosy-red or reddish-yellow, sometimes

with a coppery lustre ; the head and prothorax sparsely pubescent, very slightly shining, and much more

coarsely and less densely punctured than in S. rubricollis ; legs variable in colour—black or piceous-brown,

in the examples with pale elytra with the basal half of the four hinder femora, and the inner part of the

anterior femora nearly to the apex, testaceous; beneath thickly pubescent, very closely and finely

punctured, flavo-testaceous in light-coloured examples and almost entirely piceous in dark-coloured ones,

the flanks of the prothorax more or less suffused with cyaneous or violaceous; the rest as in S. rubricollis.

3. Fifth ventral segment very deeply triangularly emarginate; the sixth with the lateral lobes long and

spoon-shaped and protruding far beyond the apex of the fifth.

Hab. Guatemata, Sinanja and Senahu in Vera Paz (Champion).

One male and three female examples; the elytra are in two examples brownish-

yellow and in the other two (¢ 2) bluish-black or blackish-brown. As in S. rudri-

collis, the flanks of the prothorax are more cr less stained with violaceous and almost

bare. The very different sculpture of the head and thorax, longer and more slender

antenne, and other particulars, separate it easily from S. rubricollis. ‘The latter has

the head and elytra very constant in colour, while in the present insect the reverse is

the case,

9. Sisenes telephoroides.

Elongate, finely pubescent, subopaque, the head and prothorax slightly shining; the head bronze or greenish-

bronze, the anterior part flavous, the labrum and tips of the mandibles piceous ; the prothorax orange-

yellow ; the scutellum flavous or piceous; the elytra bronze-black or blackish-violaceous, sometimes of

a plumbeous tint. Head distinctly broader than the prothorax, still broader in the male, closely and

rather coarsely punctured, the eyes small; antennz moderately long, comparatively stout, black or piceous-

brown, joint 2 not half the length of 3; prothorax as long as broad, shorter in some examples, the sides

moderately rounded in front and feebly constricted behind, the base grooved within the prominent margin,

the disc broadly transversely depressed in front, with a shallow depression on each side behind the middle

(not always distinct), and an interrupted median ridge, the surface closely and rather coarsely punctured ;

elytra moderately long, parallel, densely, confluently, and rather coarsely punctured, and with oné costa

on the disc (the usual one between this and the suture obsolete) and another at the sides, the inner one _

of these obliterated beyond the middle in some specimens and in others continued nearly to the apex, the

suture also raised; beneath closely and finely punctured and pubescent, the meso- and metasternum and

the venter (except in the middle) eneous or sneo-piceous, the rest flavous; legs slender, variable in

colour—piceous or brown with the base of the femora more or less testaceous, in some examples with the

basal half or two-thirds of the latter abruptly flavous—the penultimate joint of the tarsi tomentose

beneath.

Silis and Telephorus. The ten specimens obtained vary a good deal inter se: in some

‘SISENES. 137

of them the second costa on the elytra is continued nearly to the apex, and in others it

only reaches to about the middle ; the usual first costa is obsolete in all. ,

shallow oblique depression on each side behind the middle, and sometimes with traces of a smooth median

line or ridge, the surface densely and finely punctured; elytra moderately long, parallel, densely and

rather finely punctured, and with two fine coste on the dise and one at the sides, the two outer ones

nearly reaching the apex and the inner one extending nearly to the middle, the suture also raised; beneath

closely and finely punctured and pubescent, obscure neous, the prothorax coloured as above but with the

lower part of the flanks zneous ; legs slender, piceous, the basal two-thirds of the femora, and sometimes

the tibie in part, testaceous, the penultimate joint of the tarsi tomentose beneath.

Length 42-53 millim. (9.)

Hab. GuatTeMaLa, Sinanja in Vera Paz (Champion).

Four examples. Closely allied to the Mexican S. telephoroides, and differing thus :—

in front of this, and traces of a fine median ridge (the depressions almost, and the median ridge quite,

obsolete in one example), the surface closely and rather coarsely punctured; elytra moderately long,

parallel, densely and rather coarsely punctured, and with two fine cost on the disc and one at the sides,

the two outer ones extending nearly to the apex and the inner one to about the middle, the suture also

Two examples from Chiriqui and one from Nicaragua (the latter in a mutilated con-

dition), apparently all females. The Nicaraguan specimen has the elytra violaceous and

the antenne darker, but otherwise agrees with those from Chiriqui. The reddish-

Elongate, finely pubescent, slightly shining; the head bronze, the anterior part reddish-yellow, the labrum

and tips of the mandibles piceous; the prothorax reddish-yellow; the elytra piceous with an «neous

lustre. Head broader than the prothorax, closely and coarsely punctured, the eyes small; antenne

Hab. Mexico, Oaxaca (Hége).

One example, apparently a female. The more shining, almost unimpressed, more

coarsely and more deeply punctured, rather narrower thorax, and the more coarsely

sculptured and less opaque elytra distinguish this species from S. telephoroides.

Elongate, finely pubescent, subopaque, the prothorax shining; the head greenish-eneous or red with the

extreme base piceous, the anterior portion yellowish or red, the labrum, tips of the mandibles, and palpi

piceous ; the prothorax red with a coppery lustre; the elytra blackish-violaceous. Head closely and

comparatively coarsely punctured, the eyes small; antenne black, moderately long, rather stout, joint

2 about half the length of 3; prothorax nearly as long as broad, the sides moderately rounded in

front and feebly constricted behind, the base deeply grooved within and with prominent margin, the disc

with a broad deep transverse depression on each side in front, a very deep, laterally extended, and

more sinuous one on each side just behind the middle, and an interrupted median ridge, the surface

coarsely and rather sparsely punctured, the transverse sinuous elevations separating the deep depressions

smoother; elytra moderately long, parallel, densely and rather coarsely punctured, and with two fine

sharply defined costz on the disc and one at the sides, the inner one abbreviated before the apex, the

pubescent ; legs black, slender, the penultimate joint of the tarsi tomentose beneath.

Length 63-63 millim. (9.)

Hab. Mexico (Sallé), Oaxaca (Hoge).

* Two examples, both females. Broader than S. viridipennis; the antenne very much

stouter; the thorax subquadrate and with the hind angles not prominent, less finely

punctured, more opaque, rosy-red, with the basal margin in the middle and the flanks

violaceous ; the elytra piceous-brown with a faint brassy (not greenish) lustre, and

the first costa extending far beyond the middle; the legs a little stouter.

2. Antenne with joints 3-5 a little thickened in the female, subfiliform or slightly

Hab. Mexico, Tapachula in Chiapas (Hége); GuatemaLa, Rio Naranjo, El Reposo,

Zapote (Champion).

Two examples from Mexico and seven from Guatemala, all but one from the lower

part of the Pacific slope. As in several of the allied forms, the elytra vary a good

deal in colour. The intermediate joints of the antenne of the female are thicker than

in the male. The dark stripe down the disc, the prominent median ridge, on either

distinguish this species from all others of the genus. In one of the Mexican examples

the elytra have the basal half indeterminately testaceous.

A female specimen from El Reposo is figured.

16. Sisenes eximius. (Tab. VI. figg. 20,9, var.; 21,6.)

Moderately elongate, thickly pubescent, opaque; the head blackish- or greenish-bronze, the sides of the front

and mandibles flavous, the tips of the latter, the epistoma, and labrum piceous; the prothorax orange or

ochraceous, with a blackish-eneous or blackish-violaceous stripe on each side of the disc; the scutellum

ochraceous ; the elytra variable in colour—-usually bluish-black or very dark violaceous with the basal

half-or more of the sides broadly, and the suture for a very short distance helow the scutellum, ochraceous,

or, more rarely, ochraceous with a narrow oblique dark violaceous stripe on each elytron running from the

and with two fine costz on the disc and one at the sides, the inner one extending to about the middle

and the others nearly to the apex, the suture also raised; beneath finely and closely punctured and

pubescent, piceous, with an seneous lustre; legs slender, black or brownish, the penultimate joint of the

tarsi tomentose beneath.

3. Fifth ventral segment very feebly emarginate; the sixth with the lateral lobes short and clothed with

long hairs.

Length 43-63 millim. (¢ 2.)

Hab. Panama, Bugaba, Volcan de Chiriqui, David (Champion).

Numerous examples, the majority of them being females. This little species is

allied to S. dilaticornis, from which it may be distinguished by its smaller size and

much shorter and differently-coloured elytra, and also by the less dilated intermediate

joints of the antenne in the female. As in the allied forms, the male seems to be

much rarer than the female.

We figure a typical male and a variety of the fondle. both from Bugaba.

3. Antenne with joints 3-5 much thickened in both sexes (at least in 8. lyciformis and

S. mimetes) ; eyes feebly emarginate ; elytra with fine coste. Species Lyciform.

17. Sisenes dilaticornis. (Tab. VI. fig. 22, 2.)

Moderately elongate, thickly pubescent, opaque, ochraceous, the head (except in the middle behind and at the

sides in front) bronze, the prothorax with a piceous stripe on each side of the disc, the stripe sometimes

continued on to the base of the elytra. Head as wide as the prothorax, very closely and finely punctured,

the labrum and the tips of the mandibles piceous, the eyes small ; antennx ( Q ) black or fusco-ferruginous,

moderately long, stout, with the joints from the third somewhat flattened, tapering outwardly and with

joints 3-5 broader than the others, joint 2 short; prothorax subquadrate, the sides a little rounded in

confluent behind, the suture also distinctly raised; beneath closely and finely punctured and pubescent,

piceous, the venter and prothorax sometimes brown; legs piceous or brown, the penultimate joint of the

tarsi tomentose beneath.

Hab. Nicaracua, Chontales (Belt, Janson).

Four examples.

18. Sisenes suturalis. (Tab. VI. fig. 23, ° .)

Elongate, thickly pubescent, very opaque, ochraceous, with the space between the points of insertion of the

antenne and the sides of the head, the labrum, the tips of the mandibles, the sides of the prothorax in

front, and the suture of the elytra very narrowly to beyond the middle, piceous-black. Head as wide as

the prothorax, densely and finely punctured, the eyes rather small; antenne ( @ ) black, moderately long,

very stout, tapering outwardly and with joints 3-5 much thicker than the others, joint 2 short ; prothorax

distinctly longer than broad, the sides very feebly rounded before the middle, a little constricted behind,

and shallowly emarginate in front immediately before the apex, the front and hind angles slightly

prominent, the base grooved within, the disc with a large oblique rather deep depression on each side just

behind the middle and very shallowly transversely depressed on either side in front of this, the surface

densely and finely punctured ; elytra very long, subparallel, densely and rather finely punctured, and with

two prominent coste on the disc and one at the sides, the inner one not reaching the apex and the two

outer ones confluent behind, the suture also distinctly raised ; beneath closely and finely punctured and

pubescent, entirely piceous; legs rather slender, brownish-black, the penultimate joint of the tarsi

tomentose beneath.

Length 9 millim. (@.)

Hab. Muxico, Cerro de Plumas (Hége).

One example. The much more elongate shape, larger size, differently-formed

antenne, &c. distinguish this insect at once from S. délaticornis.

19. Sisenes lyciformis. (Tab. VI. figg. 24,3; 24a, labium; 24 6, maxilla and

maxillary palpi; 24 ¢, edeagus.)

Elongate, the head and prothorax sparsely, the elytra thickly, pubescent, opaque; the prothorax and the basal

half of the head coppery- or crimson-red, the anterior portion of the latter bronze or obscure violaceous,

and the sides of the front and the mandibles pale flavous, the labrum and palpi piceous; the elytra

black, blackish-brown, or brown, often with a violaceous or coppery tint in certain lights, the shoulders (or

the sides for some distance), and sometimes the extreme base or a longitudinal space on either side of the

suture in front, brownish-yellow. Head about as wide as the prothorax in the female, broader in the

male, densely and rather coarsely punctured, the eyes small; antenne black, rather long, tapering out-

wardly, joint 2 short, joints 3-5 very much stouter than the others in both sexes but much stouter in the

female than in the male, the following joints comparatively slender; prothorax subquadrate, the sides

slightly rounded’ before the middle and feebly sinuate behind, the hind angles rather (and sometimes the

front angles slightly) prominent, the base grooved within, the disc with a large deep oblique depression on

each side behind the middle, shallowly transversely depressed in front, and with an interrupted more or

less distinct median ridge, the surface coarsely, closely, and roughly punctured, the punctuation much

coarser and rougher than that of the head; elytra long, a little flattened on the disc, narrow and more

parallel in the male, broader and widening to beyond the middle in the female, the surface very densely

punctured, and with two fine rather sharp coste on the disc and one at the sides, the inner one not

reaching the apex, the suture also distinctly raised, the apices obtuse and divergent; beneath closely

and finely punctured and pubescent, rather shining, piceous or piceous-brown with an ‘neous lustre, the

sides of the meso- and metasternum more or less violaceous, the head and prothorax brilliantly so, the

epipleure coppery or violaceous ; legs slender, black or brownish, the coxe pale testaceous, the penultimate

joint of the tarsi tomentose beneath.

3. Fifth ventral segment rather deeply emarginate ; the sixth with the lateral lobes projecting considerably

beyond the fifth and hairy at the apex.

Length 7-93 millim. (¢ 2.)

Hab. Guatemaua, Purula, Sabo, and Sinanja in Vera Paz (Champion).

Found in profusion by myself in the humid forest-region of the Atlantic slope at

elevations of from 1500 to 4000 feet. The insect superficially resembles Calleros sinanje,

Gorh., a species of Lycide inhabiting the same district, and, like it, is found resting

upon leaves in the moist forest. The thorax is much more coarsely and more roughly

punctured than the head and is of a uniform crimson- or coppery-red colour. The

elytra in certain lights appear purplish or violaceous, and their colour is obscured

by the brownish pubescence. A female example is figured.

20. Sisenes mimetes. (Tab. VI. fig. 25, 9 .)

Allied to S. lyciformis, and differing as follows :—The head closely and rather coarsely punctured, with the

sides piceous, dark bronze, or blackish-violaceous, a longitudinal space in the middle behind (narrowing

anteriorly and becoming broader towards the base) reddish or flavous; the prothorax yellowish- or brick-

red, with the sides in front narrowly violaceous, the surface densely and rather coarsely punctured ; the

elytra black, blackish-violaceous, or blackish-brown, with the sides to about the middle (very broadly at

the base and rapidly becoming more narrowly so) ochraceous ; the rest as in S. lyciformis.

Length 63-9 millim. (¢ @.)

Hab. Mexico, Cordova (Sallé), Jalapa (Hége).

Five examples. The very much finer and less rough punctuation of the thorax and

the differently-coloured upper surface distinguish this species at a glance from S. /yci-

formis, with which it agrees closely in size, shape, and sculpture. The antenne have

joints 83-5 very much thickened. This species, like many others of widely different

families, bears a remarkable resemblance to certain Lycide inhabiting the same dis-

tricts, a similar system of coloration and general facies—and, to a certain extent, form

of antenne—existing in various Central-American Longicornia, Hispide, Galerucide,

Lagriide, and Meloide.

21. Sisenes personatus. (Tab. VI. fig. 26, ¢ .)

Elongate, thickly pubescent, opaque; the head black, a narrow longitudinal space down the middle behind

ochraceous, the sides of the front and the mandibles (the tips excepted) flavous, the labrum black ; the

prothorax black, with a broad longitudinal band down the middle, and the sides narrowly at the’ base,

ochraceous; the scutellum ochraceous ; the elytra black, with a short lateral stripe at the base (starting

from the shoulder and gradually narrowing behind) ochraceous. Head about as wide as the prothorax,

densely and rather finely punctured, the eyes small ; antenne ( @ ) black, rather long, tapering outwardly,

joint 2 very short, joints 3-5 very much stouter than the others ; prothorax comparatively large, broader

than long, the sides a little rounded anteriorly and very slightly sinuate behind, the hind angles some-

the base grooved within and with prominent margin, the surface densely and finely punctured; elytra ( 9)

long, flattened on the disc, widening to far beyond the middle, the surface very densely punctured, each

elytron with four fine coste (the first not reaching the apex, the second and fourth confluent immediately

before the apex and enclosing the third, the latter short, much less distinct, and in a line with the

shoulder), the suture also raised, the apices obtuse and divergent; beneath very finely and closely punc-

tured and pubescent, black with an sneous lustre, the flanks of the prothorax bright violaceous ; legs

black, comparatively stout, the penultimate joint of the tarsi tomentose beneath.

Length 94 millim. (9.)

Hab. Nicaragua, Chontales (Janson).

One specimen only of ‘this very distinct species has been received. Larger and

broader than the corresponding sex of S. méimetes; the thorax broader than long, and

with two deep oblique grooves on each side of the disc; the elytra with an additional

costa on each; the upper surface differently coloured. Specimens of a closely allied

species from the Amazons are contained in Mr. F. Bates’s collection *,

VODOMARUS.

Last joint of the maxillary palpi oblong-ovate, narrow, the apex obliquely truncate, that of the labial palpi

oblong-ovate; mandibles deeply cleft at the apex; mentum strongly transverse; head moderately

produced in front; eyes entire (the inner edge not sinuate or emarginate), oblong-oval, lateral, very finely

granulated, moderately large; antenne slender, filiform, moderately long, 11-jointed,—1 and 3 about

equal in length, 2 not quite half the length of 3, 3 and the following joints subequal ; prothorax trans-

verse; elytra moderately long, very gradually narrowing from the base, without raised or impressed lines

on the disc, completely covering the wings, the apices obtuse and somewhat divergent; legs slender, the

femora not dilated in the male ; tibial spurs short; claws sharply toothed within near the base.

A single species from Central America is referred to this genus. Vodomarus

approaches the Old-World genus demera, but differs from it in the oblong-ovate and

shorter apical joint of the maxillary palpi, less subulate elytra, less elongate antenne,

the first and third joints of which are about equal in length, and toothed claws. The

oblong-oval and entire eyes, toothed claws, and more attenuate elytra distinguish it

from Sisenes.

1. Vodomarus quadrifoveolatus. (Tab. VII. figg. 1, 1 a, labium; 1 4,

Smaller, narrower, and more parallel than S. personatus; black or blackish-violaceous, the head in the middle

behind and in front, the prothorax with the sides narrowly (in one example at the base only) and a broad

stripe down the middle, the scutellum, the elytra with the suture for a short distance and in one example

the sides from the base nearly to the middle (but narrowly so behind), orange-yellow ; antenne ( 9 ) black

more slender than in S. personatus, joints 3-5 stouter than the others ; elytra with two fine sharp coste

prothorax flavous, with a median vitta (narrowing a little behind and not quite reaching the base) and the

sides very narrowly (the piceous marking on the flanks just visible from above) piceous; the elytra piceous,

each with a rather broad pale flavous vitta on the disc near the suture. Head very finely and thickly .

punctured ; prothorax rather convex, transverse, not so wide as the head, scarcely narrower at the apex

than at the base, the sides a little sinuate behind and feebly rounded, the disc with a long deep oblique

depression on either side behind the middle (the depressions separated from each other by a median ridge),

a transverse depression on each side in front, and a deep transverse one in the centre at the base, the

basal and apical margins raised, the former grooved within and slightly emarginate in the middle, the

surface very finely and closely punctured ; elytra a little flattened on the disc, longitudinally grooved at

the base near the shoulders, and with a sharp carina below the latter running parallel with the lateral

margin nearly to the apex, the suture also sharply raised, the surface very finely and closely punctured ;

beneath densely punctured, piceous, the prothorax (except the flanks) and the venter (except the hind

margins and sides of the segments) more or less flavous or testaceous; legs flavous or testaceous, the

tibiz and tarsi and the tips of the four hinder femora brownish or piceous.

Length 4-43 millim. (<¢.)

Hab. Mexico (Sallé); Guatemata, Sinanja in Vera Paz (Champion); Panama,

Bugaba (Champion).

One example only from each locality. The specimen from Bugaba is immature and

has the head and thorax flavous, the elytral vitta much broader, and the depressions on

the thorax shallow. The elytra do not exhibit the slightest trace of impressed or

raised lines on the disc, though the suture is sharply raised and there is a sharp carina

running along the side close to the lateral margin.

COPIDITA.

Copidita, Leconte, New Species Col. p. 164 (1866).

~ Numerous species from Central America are provisionally referred to Copidita.

They chiefly differ from the type of the genus, C. quadrimaculata (Motsch.), from

Sitkha and California, a male example of which is contained in the British Museum,

in having comparatively shorter elytra and less elongate antenne, and the fifth ventral

segment unemarginate laterally in the male; and from Osacis in the bifid mandibles.

The form of the head, eyes, and thorax is similar to that of Oxacis; the eyes, as in the

type, are coarsely granulated (in one species, C. nigripennis, they are much more finely

granulated); the penultimate joint of the tarsi (as in the type) is spongy-tomentose

beneath ; the claws are feebly dilated at the base; the antenne have eleven joints in

both sexes, the eleventh constricted or emarginate at the middle, the first about as long

as the third. Numerous undescribed species from Tropical South America, the

Antilles, Tahiti, &c. are, no doubt, congeneric with those from Central America; but

of the various species from the Antilles referred to Copidita by Mr. C. O. Waterhouse,

probably one only, C. dateralis, having bifid mandibles, really belongs to it as here

understood.

COPIDITA. 145

1. Eyes coarsely granulated, moderately large.

* Last joint of the maxillary palpi cultriform or subcultriform.

1. Copidita panamensis. (Tab. VII. fig. 2.)

Very elongate, opaque, brownish-yellow or yellowish-brown, thickly clothed with rather coarse yellowish

pubescence. Head densely and finely punctured, more sparsely so in front, the eyes and the tips of the

mandibles black or piceous, the eyes comparatively small; antenne testaceous, joints 1 and 3 about

equal in length, 11 strongly constricted a little beyond the middle; prothorax longer than broad, the

sides rounded anteriorly and converging behind, the disc broadly concave in front, largely depressed.

in the middle behind, and with a large oblique depression (shallow in one example, deeper in the other)

on either side anteriorly extending to the anterior angles, the anterior margin considerably raised, the

surface densely and finely punctured (a rather broad longitudinal space on the middle of the disc

impunctate in one example); elytra long, broadest beyond the middle, closely and more coarsely

punctured than the prothorax, and with three distinct feebly raised lines on the disc and one at the sides

extending nearly to the apex, the suture also raised; beneath testaceous, densely punctured; legs

testaceous, the extreme apices of the femora piceous.

Length 11-113 millim. (9.)

Hab. Panama, Bugaba (Champion).

Two examples. This is a comparatively large species, brownish-yellow in colour,

with the tips of the femora darker; the thorax is broadly concave in front and

depressed on either side of the disc before the middle; the elytra have three raised

lines on the disc and the suture also raised. The apical joint of the maxillary palpi

is long and subcultriform, and the mandibles are bifid. C. panamensis is not

very closely allied to any other species here noticed from Central America; but

an allied undescribed one from Venezuela is known to me, and the following comes

near it.

2. Copidita scabrosa.

Moderately elongate, opaque, brown, thickly clothed with rather coarse pubescence. Head very closely and

somewhat coarsely punctured, the eyes and the tips of the mandibles piceous, the eyes rather small ;

antenne testaceous, rather stout, joint 1 about as long as 3 (11 missing); prothorax longer than broad,

the sides strongly rounded anteriorly, slightly emarginate in front just before the rather prominent

anterior angles, and rapidly converging behind, the disc broadly concave in front, flattened in the middle

behind, and largely and deeply depressed on either side before the middle, the anterior margin considerably

raised and with_a triangular prolongation on the inner side in the centre, the surface densely and sub-

rugulosely punctured ; elytra comparatively short, rather more coarsely and more rugulosely punctured

than the prothorax, with three raised lines or coste on the disc and one at the sides, the suture

also raised, the latter and the coste accompanied on either side by a faint fuscous line; beneath

testaceous, densely punctured ; legs rather stout, testaceous, the extreme apices of the femora a little

darker.

Length 64 millim.

Hab. Guatemata, Capetillo (Champion).

on the latter this species differs from all others of the genus here recorded. ‘The raised

anterior margin of the thorax is triangularly prolonged inwards at the middle. The

last joint of the maxillary palpi is elongate aad subcultriform. The dense punctuation

of the thorax and elytra, that of the thorax much finer, differently formed palpi, bifid

mandibles, and other particulars distinguish it from Oxacis pilosa.

Hab. Nicaragua, Chontales (Belt).

One example only. In this species the thorax is long, much narrowed behind,

and has three deep depressions, and its basal and apical margins are raised; the elytra

have two distinct raised lines on the disc; the apical joint of the maxillary palpi is

subcultriform ; and the mandibles are bifid.

4, Copidita maculicollis. (Tab. VII. fig. 4, ¢.)

Elongate, thickly clothed with rather coarse pubescence; the head and prothorax slightly shining, testaceous

or flavo-testaceous, the former broadly infuscate between the eyes, the latter with the anterior half

marked with piceous or brown (this colour surrounding two or three flavous spots on each side of the

disc and divided along the middle by an extension of the ground-cclour, sometimes extending along the

lateral margin and on either side of the disc to the base); the elytra opaque, brownish-testaceous or

brown. Head finely and thickly (in some specimens more coarsely) punctured, the eyes and the tips of

the mandibles black, the eyes coarsely granulated, the oral organs testaceous or fusco-testaceous ; last joint

of the maxillary palpi long and cultriform, much longer in the male than in the female; antenne long

and slender, testaceous with the outer half of each joint (the first excepted) fuscous or piceous, or fuscous

constricted at the middle in both sexes; prothorax longer than broad, the sides rounded anteriorly,

feebly sinuate or emarginate just before the apex, constricted at the middle, and thence to the base con-

verging, the disc depressed in the centre before the base and with a large and deep depression on each side

before the middle, the basal and apical. margins raised, the surface very closely and finely (in some

specimens very densely) punctured, a narrow space along the middle of the disc smoother in some examples ;

Hab. Mexico, Santecomapan (Sal/é). Gana rar, m Uipe-arwo

One example.

This is a widely distributed and variable species. The description is taken from the

numerous specimens from the Volcan de Atitlan. In well-marked examples the dark

patch on each side of the thorax in front assumes the form of an eye-like spot, and

there is often a spot in front of this and another one external to it; in some specimens

the thorax is fuscous, with a central vitta and three spots placed one below the. other

on each side (the hinder one much the largest) flavous or testaceous. The last joint of

the maxillary palpi is long and cultriform, and much longer in the male than in the

female; the mandibles are bifid. In some examples the suture and the raised lines

on the elytra have an interrupted faint fuscous line on either side, this line formed by a

series of very shallow longitudinal impressions which are fuscous within. Our figure is

taken from a typical male example from Pantaleon.

5. Copidita palpalis.

Closely allied to C. maculicollis and differing thus: the head infuscate between and behind the eyes; the

prothorax with the sides very broadly, and a narrow median vitta towards the base (the vitta confluent

on each side with the lateral marking in one example), infuscate; the elytra as shining as the prothorax,

with a series of shallow oblong fuscous impressions along the suture and on each side of the raised

lines; the last joint of the maxillary palpi very elongate and cultriform in the male.

Length 81-9 millim. (<d.)

- Hab. Guatemata, Capetillo (Champion).

of C. maculicollis, and the mandibles are bifid.

** Last joint of the maxillary palpi shorter, subtriangular.

6. Copidita apicalis. (Tab. VII. fig. 5.)

Elongate, narrow, thickly clothed with rather coarse pubescence ; the head and prothorax rather shining, the

former testaceous with a broad longitudinal infuscate stripe on the middle of the vertex, and the anterior

half and the greater part of the mandibles pale flavous, the latter reddish-testaceous ; the elytra opaque,

fuscous, the suture rather broadly throughout, the lateral margin narrowly (but not visibly so from above),

and a transverse fascia (extending completely across) just before the apex, very pale flavous, the base and

the apex of a darker fuscous tint. Head rather broad, very closely and moderately finely punctured, the

eyes and the tips of the mandibles black ; palpi fusco-testaceous, the last joint of the maxillary pair

elongate-triangular and with its apical side a little longer than the inner side; antenne fuscous, filiform,

joints 1 and 3 about equal in length, 11 constricted at the middle; prothorax narrower than the head,

the sides rounded anteriorly, constricted at the middle, and thence to the base subparallel, the disc a little

flattened in the centre at the base and with a rather large depression on each side before the middle and a

smooth central line, the surface very closely and moderately finely punctured; elytra densely and much

more coarsely punctured than the prothorax, and with two fine raised lines on the disc; beneath

densely punctured, piceous, the prothorax testaceous with the flanks darker towards the apex ; legs pale

flavous, the apical half of all the tibie piceous-brown, the tarsi partly, and the femora towards the

apex, infuscate.

Length 5 millim.

Hab. Paxama, Bugaba (Champion).

This small narrow species differs from all the allied forms in the coloration of the

elytra. One specimen only was obtained, apparently a male.

7. Copidita parvula. (Tab. VII. fig. 6.)

Elongate, narrow, finely pubescent, opaque; the head flavous, with a Y-shaped median stripe and the sides

behind the eyes brown or piceous ; the prothorax flavous, with a broad median stripe, widening behind,

and the sides narrowly (but not visibly so from above in one example), piceous; the elytra piceous or

piceous-brown, the suture sometimes a little lighter. Head densely and finely punctured, the eyes and

the tips of the mandibles black, the former large and coarsely granulated; antenne black or piceous,

rather stout, tapering outwardly, joint 1 a little longer than 3, 11 constricted at the middle; prothorax

longer than broad, narrower than the head, the sides rounded anteriorly, constricted at the middle, and

thence to the base subparallel, the dise shallowly depressed in the middle behind and with a shallow

oblique depression on each side anteriorly, the surface densely and finely punctured ; elytra densely and

very much more coarsely punctured than the prothorax, and with three fine raised lines on the disc, the

suture also a little raised; beneath densely punctured, piceous or fuscous, the prothorax (the flanks

excepted) lighter; legs testaceous or flavous, the apices of the femora and the tibie (except at the base)

piceous or brownish,

Length 37-44 millim.

maxillary palpi is broad and similarly shaped. The antenne taper outwardly, joints

1-5 being stouter than the others. C. parvula somewhat resembles Sisenes lineatocollis,

from which it may be at once distinguished by the coarsely granulated and larger eyes,

broad apical joint of the maxillary palpi, posteriorly constricted thorax, shorter head,

&c.

2. Hyes finely granulated, small ; last joint of the maxillary palpi subtriangular.

8. Copidita nigripennis. (Tab. VII. fig. 7.) 3

Elongate, narrow, opaque, thickly clothed with rather coarse ashy pubescence; the head (the basal part of

the mandibles excepted) black; the prothorax reddish-yellow, slightly stained with piceous at the base in

front of the scutellum ; the elytra bluish-black. Head densely and very finely punctured, the eyes rather

small and finely granulated ; antenne piceous, the two basal joints fusco-testaceous, stout, rather short,

joints 1 and 3 about equal in length and comparatively short, 1 very stout, 2 half the length of 3, 11

strongly constricted at the middle; prothorax convex, much longer than broad, the sides moderately

rounded anteriorly and gradually converging behind, the disc canaliculate in the centre at the base and

with a very shallow oblique depression on either side before the middle, the surface densely and very

finely punctured; elytra comparatively short, very obtuse behind, the surface scabrous and with indistinct

traces of very fine raised lines; beneath densely punctured, piceous or black, the prothorax reddish-

yellow ; legs thickly pubescent; rather stout, piceous, the tibize and coxe fusco-testaceous.

Length 63-7 millim.

Hab, Mexico (Sallé).

Three examples, all in a bad state of preservation, apparently females. This species,

which is not labelled with any more exact locality, closely resembles a Chilian insect

described by Fairmaire under the name of Nacerdes brevipennis; from which it differs

in the head and thorax being more finely punctured, the latter more convex, with the

impressions shallower and the median ridge obsolete; the antenne shorter and stouter,

and with a very stout basal joint; the elytra more scabrous and unicolorous. The last

joint of the maxillary palpi is stout and elongate-triangular, with its inner side much

shorter than the apical side; the mandibles are bifid. In all three examples the ashy

pubescence of the elytra is more dense along the suture and at the sides, but this is

probably due to abrasion.

This will probably prove to be the most widely distributed genus of the Cidemeride ;

and, as understood here, it contains a large number of species from the warmer parts

of the Old and New Worlds, the Antilles, various Oceanic islands (Sandwich Is., Tahiti),

Fiji, New Caledonia, &c. ; it is, however, absent from Europe. ‘The only species hitherto

150 HETEROMERA.

referred to it are from North America, Colombia, or the Antilles; but very many of

those included in Ananca, by various authors undoubtedly belong to it. The last-named

genus was not characterized by its authors: of the five species enumerated as belonging

to. it, all of which are from Chili, one only is known to me, A. serville (Sol.), and this

is not congeneric with the Central and North-American species of Oxacis; A. servillei

agrees with Oxacis in the simple form of the mandibles (cf. Solier, in Gay’s Hist. fis. y

polit. de Chile, Zool. v. Atlas, t, 21. fig. 4 bis d), but differs in its longer head and more

depressed and more oblong eyes. The species here referred to Oxacis agree in having

the mandibles entire at the apex *; the antenne 11-jointed, with the apical joint usually

constricted or emarginate at or beyond the middle, in both sexes; the eyes coarsely

granulated (except in O. dugesi), very widely separated, oblique, and not prominent,

usually large, and, at most, feebly sinuate or emarginate on their inner edge; the last

joint of the maxillary palpi varying from subcultriform to subtriangular; the thorax

oblong-cordate, always narrower at the base than at the apex; the anterior tibie with

two spurs; the tarsi (except in O. variegata) with the penultimate joint only spongy-

tomentose beneath; the claws toothed or angularly dilated, or, usually, only feebly

dilated, at the base; the fifth ventral segment unemarginate in both sexes. Of the

ten species from North America included by Leconte and Horn in Ozacis, examples of

seven of which are before me, two at least, O. notoxoides and O. thoracica (Fabr.), have

bifid mandibles, and these do not belong to the genus as here understood ; the former

is apparently referable to Ditylus and the latter to Copidita. Hypasclera, Kirsch, based

upon three species from Colombia, is, no doubt, congeneric with Ovacis; and of the

numerous species of Copzdita from the Antilles described by Mr. C. O. Waterhouse

(cf. Trans. Ent. Soc. London, 1878, pp. 306-309) all but one, C. lateralis, probably

belong to the same genus, these having, apparently, the mandibles entire at the apex.

In two of the species from Central America the posterior femora are much thickened

in the male; this character, however, as in @demera, is not of generic importance.

Various species from North and Central America, chiefly those frequenting the sea-

shore, have the claws toothed within at the base; but as there are numerous others

with the claws angularly or subangularly dilated, and many in which the dilatation is

very feeble, this character cannot be regarded as of generic value ; the two species from

North America with toothed claws were supposed by Leconte to belong to Prodosca.

Elongate, opaque, thickly clothed with short ashy pubescence ; testaceous or pallid tosticdi, the prothorax

with a median stripe, and sometimes the sides very narrowly at the middle, and the elytra with a narrow

stripe near the suture and a broader one at the sides, confluent just before the apex, brownish or piceous.

Head closely and finely punctured, the eyes and the tips of the mandibles black; antenne testaceous, the

eleventh joint scarcely emarginate; prothorax longer than broad, the sides strongly rounded anteriorly

and gradually converging behind, the disc depressed in the middle before the base and with a large shallow

depression on either side anteriorly, the surface densely and finely punctured ; elytra subparallel, finely,

densely, and shallowly punctured, and sometimes with traces of one or two raised lines on the dise, the

apices very obtuse ; beneath densely and finely punctured, testaceous, the last three ventral segments and

Hab. Mexico, Juquila (Sallé), Morelia in Michoacan (Hdge).

Five examples, including both sexes from each locality. This and the following

species may be known from all others of the genus by the much thickened posterior

femora of the male. The female of O. femoralis closely resembles O. /ucana (Lec.), but

differs in the more finely punctured thorax, more parallel shape, and less sharply toothed

claws. O. femoralis is apparently confined to inland localities. Labelled dnanca

Hab. Guatemaa, San José (Champion); Panama, near the city (Champion).

Four male and two female examples, all from the Pacific coast; one only from

Panama. This insect was found in both localities in company with O. litoralis. It differs

from the latter in the finer punctuation of the head, the less close and shallower

punctuation of the thorax, and the differently marked elytra; the claws are only feebly

dilated at the base, and the posterior femora in the male are much thickened. From

O. femoralis, the much coarser and sparser punctuation of the head and thorax and the

less closely punctured elytra sufficiently distinguish it; the male of the present species

has the inner apical angle of the hind tibie armed with a very short tooth.

4. Oxacis holosericea. (Tab. VII. fig. 9.)

Elongate, opaque, densely clothed with very fine silky cinereous pubescence; testaceous or pallid testaceous,

the prothorax with the sides rather broadly and a median stripe (the latter somewhat interrupted at the

middle), and the elytra with two broad vitte which are confluent just before the apex (leaving only the’

suture, the lateral margin, and a discoidal stripe of the pallid ground-colour, the discoidal stripe indistinct

in one example), brownish or piceous. Head very closely and finely punctured, the eyes and the tips of

the mandibles black; antenne testaceous, the basal joints sometimes slightiy stained with piceous, the

eleventh joint constricted at the middle in both sexes ; prothorax longer than broad, convex, the sides a

little rounded in front and gradually converging behind, the disc longitudinally depressed in ‘the centre

before the base (canaliculate in the middle in one example) and with a very shallow indistinct depression

on either side anteriorly, the surface densely and minutely punctured; elytra subparallel, punctured like the

prothorax, and without distinct raised lines ; beneath densely and minutely punctured, pallid testaceous, the

flanks of the prothorax, the sides of the metasternum, and (sometimes) the sides of the venter stained with

piceous ; legs testaceous, the knees sometimes a little darker, the femora similar in both sexes, the claws

very distinctly toothed at the base.

The claws are toothed at the base as in O. lucana. The right mandible is armed on

the inner upper side near the tip with a small tooth, as in O. dorsalis, Lec. In one

example the vitte of the elytra are only separated by a narrow indistinct stripe.

In the National Collection there is an example of a species very closely allied to

this, but differing from it in having simple claws; it is from Pensacola and may be

referable to O. teniata, Lec.

5. Oxacis mandibularis. (Tab. VII. fig. 10, 2.)

Elongate, opaque, clothed with very fine short ashy pubescence ; the head and prothorax pale testaceous, the

latter with a large patch on the middle of the disc, and the sides at the middle narrowly, infuscate; the

elytra fuscous, with a discoidal stripe (starting from the middle of the base and gradually narrowing)

and the suture testaceous. Head deeply sunk into the prothorax, finely and rather thickly punctured,

sparsely so in front, the epistoma smooth, the eyes and the apical portion of the mandibles black, the latter

largely developed (when closed, projecting far beyond the sides and apex of the labrum) and simple;

antennex testaceous, joint 3 about as long as 1, 11 very feebly emarginate at the middle; prothorax about

as long as broad, broader than the head, the sides rounded in front and converging from a little before the

apex to the base, the disc flattened in the middle behind, and with a large oblique depression on each side

anteriorly and traces of a smooth central line, the surface densely and finely punctured ; elytra punctured

like the prothorax and without raised lines; beneath testaceous, densely and finely punctured ; legs

testaceous, the claws toothed at the base. .

Length 73 millim. (2.)

Hab. Mexico, Presidio (Forrer).

One example only of this distinct species was obtained. Closely allied to O. lucana

and O. holosericea; but differing from these in the more largely developed mandibles

and in having the head more deeply sunk into the thorax (much as in the European

genus Probosca), the latter wider in front and broadest just before the apex. ‘The

punctuation of the thorax and elytra is much finer than in 0. lucana, but a little

coarser and less dense than in O. holosericea. The right mandible is not toothed on

the inner upper side near the tip. The head is more deeply sunk into the thorax than

in any of the allied forms. The last joint of the maxillary palpi is triangular, its inner

and apical sides about equal in length.

This species, according to the description, would appear to be allied to 0. dorsalis;

but to differ from it in the toothed claws, and in the elytra having only a submarginal

fuscous vitta. ‘Three examples collected by Herr Hoge at Vera Cruz and another from

Mexico in Mr. F. Bates’s collection differ thus from O. dorsalis, and they are very

probably conspecific with Probosca pleuralis, Lec. ‘These Mexican specimens may also be

distinguished from O. dorsalis by having the eleventh joint of the antenne unemarginate,

are without trace of a median vitta on the thorax and of any marking near the suture

of the elytra.

7. Oxacis litoralis. (Tab. VII. fig. 11, 2.)

Elongate, opaque, somewhat thickly clothed with short ashy pubescence ; pallid testaceous or testaceous, the

head often infuscate between the eyes, the prothorax with the sides and a median stripe of variable width

(the latter often obsolete), and the elytra with a broad lateral stripe and sometimes a very short stripe on

either side of the suture at the base (the latter frequently obsolete), piceous or brown. Head coarsely and

closely punctured, the eyes and the tips of the mandibles black, the antenne testaceous or fusco-testaceous ;

prothorax longer than broad, the sides arcuate in front and gradually converging behind, the disc with a

shallow depression on each side anteriorly and transversely depressed in the middle before the base, the

surface coarsely and closely punctured ; elytra thickly and finely punctured, and usually with traces of one

or two slightly raised lines on the disc; beneath densely and very finely punctured, pallid testaceous, the

last two or three ventral segments sometimes darker; legs testaceous, the femora similar in both sexes,

Found in profusion by myself on the sea-shore at Champerico and San José, on the

Pacific coast of Guatemala. 0. litoralis is closely allied to O. /ucana (Lec.), but differs

from it in the sparser and much coarser punctuation of the head and thorax. It varies

exceedingly in size, and the male is usually (but not always) very much smaller than

the female; in about half the specimens the short stripe on the elytra on either side of

the suture at the base is obsolete. ‘The apical joint of the antenne is unemarginate in

both sexes. A fully-coloured female example from Acapulco is shown on the Plate.

8. Oxacis limbata. ,

Elongate, subopaque, thickly clothed with rather coarse ashy pubescence ; testaceous, the prothorax with a

piceous with the suture rather broadly and the lateral margin very narrowly pallid testaceous. Head

closely and rather coarsely punctured, the eyes and the tips of the mandibles black or brown, the vertex

darker in the middle in one example ; antenne testaceous, with the second and third joints infuscate ;

prothorax longer than broad, the sides moderately rounded anteriorly and gradually converging behind, the

disc depressed in the middle before the base and with a shallow depression on either side anteriorly, the

surface densely and rather coarsely punctured, the punctures coarser and less close along the middle of

the disc, the latter with traces of a smooth raised line in one example; elytra parallel to about the middle

and gradually narrowing beyond, closely and moderately finely punctured, and with one or two fine raised

lines on the disc; beneath very closely and finely punctured, testaceous, the venter more or less stained

Found in abundance by Herr Hoge on the sea-shore at Vera Cruz. The Mexican

specimens agree perfectly with others before me from Texas. The eleventh joint of

the antenne is constricted at the middle in both sexes *; the right mandible is armed

on the inner upper edge near the tip with asmall tooth; the claws are angularly dilated

10. Oxacis teapensis. (Tab. VII. fig. 12, ¢ .)

Elongate, opaque, thickly pubescent; the head testaceous at the sides and in front, for the rest brownish or

piceous, the eyes and the tips of the mandibles black, the palpi piceous; the prothorax pale yellowish-

testaceous, with the sides and a large ovate patch on the middle of the disc brown or castaneous ; the

elytra brownish or fuscous, with the suture very narrowly and the lateral margin rather more broadly

pale testaceous. Head densely and finely punctured; antenne (9) rather short, piceous, the two basal

joints and the three or four outer ones lighter, the eleventh strongly constricted at the middle; pro-

The species is not very closely allied to any other here enumerated.

11. Oxacis pictipennis, (Tab. VII. fig. 13.)

Elongate, narrow, thickly and finely pubescent; the head and prothorax shining, flavo-testaceous ; the elytra

very opaque, luteous, each with a brownish-black spot at the middle of the base and a similarly-coloured

longitudinal streak on the lateral margin just below the shoulder (not visible from above) and another on

the middle of the disc. Head broad, finely and sparsely punctured, a longitudinal space in the middle

between the eyes and the epistoma smooth, the tips of the mandibles, the last two joints of the maxillary

palpi, and the eyes black; antenna rather slender, extending to beyond the middle of the elytra, piceous,

the basal joint fusco-testaceous, the third joint shorter than the first, the eleventh constricted at the

middle; prothorax much longer than broad, the sides strongly rounded anteriorly, abruptly constricted at

the middle, and thence to the base parallel, the disc feebly canaliculate in the middle behind, the surface finely

and thickly punctured; elytra subparallel, densely and minutely punctured, and with two fine raised

lines on the disc; beneath densely and finely punctured, entirely testaceous ; legs testaceous, the tibia

and tarsi piceous.

Length 84 millim.

Hab. Guatemata, Teleman (Champion).

One specimen, apparently a male, captured by myself in the lower part of the

Polochic Valley. The peculiar coloration and other particulars mentioned above

distinguish this species at once from all the allied forms.

12. Oxacis bilineata. (Tab. VII. fig. 14, 2.)

Elongate, thickly pubescent; the head and prothorax shining, pale flavo-testaceous; the elytra opaque,

stramineous, each with a very narrow blackish-brown stripe along the lateral margin, extending from

just below the shoulder nearly to the middle and not visible from above, and a similarly-coloured very

narrow stripe on the disc, the latter extending three-fourths of the elytral length. Head finely and

sparsely punctured at the sides and behind, smooth along the middle and in front, the eyes and the tips of

the mandibles black, the apical joint of the maxillary palpi infuscate at the base; antenna ( 3) very long,

extending far beyond the middle of the elytra, slender, testaceous, joints 2-4 a little darker, 3 shorter

than 1, 11 constricted at the middle; prothorax much longer than broad, narrow, the sides moderately

rounded anteriorly, constricted at the middle, and thence to the base almost parallel, the dise shallowly

depressed in the middle behind and with a smooth median line, the surface closely and finely punctured ;

elytra subparallel, closely and minutely punctured and with one fine raised line on the disc (the usual

second line obsolete) ; beneath densely and finely punctured, pallid testaceous, the metasternum a little

darker ; legs slender, pallid testaceous, the tibiee and tarsi piceous-brown.

Length 74 millim. (¢.)

Hab. Panama, Bugaba (Champion).

One example. This species is closely allied to O. pictipennis, from which its narrower

head and thorax (the latter much less rounded at the sides anteriorly), more slender

limbs, and different elytral markings sufficiently distinguish it. The apical joint of the

maxillary palpi, as in O. pictipennis, is long and cultriform. The narrow lateral stripe

of the elytra is completely invisible from above.

prothorax rather longer than broad, the sides moderately rounded anteriorly and gradually converging

behind, the disc depressed in the middle before the base, and with a rather large depression on each side

anteriorly, the base emarginate in the centre, the surface coarsely, closely, and irregularly punctured ;

elytra closely and rather coarsely punctured, and with two raised lines or coste on the disc extending from

the base nearly to the apex, the suture also a little raised ; beneath testaceous or fusco-testaceous, closely

Length 72-94 millim. (¢ 9.)

Hab. Guatemata, San José (Champion).

Many examples of this species were found in rotten tree-stumps in the mangrove-

swaimps bordering the Pacific coast. The long coarse pubescence, hairy legs and

antenne, coarse punctuation, distinct raised lines or cost on the elytra, and somewhat

shining surface distinguish this species from all the allied forms. The last joint of the

maxillary palpi has the inner and apical sides about equal in length.

(Oxo ary)

14. Oxacis tropicalis.

Elongate, densely clothed with very fine silky pubescence; testaceous, the sides of the prothorax narrowly

(from above only visibly so from the middle to the apex), of the elytra broadly, piceous. Head finely and

somewhat thickly punctured, a space along the middle in front smoother, the eves and the tips of the

mandibles piceous; antenne rather stout, fusco-testaceous, joints 1 and 2 lighter, 3 fully as long as 1,

11 emarginate at the middle; prothorax longer than broad, the sides feebly rounded anteriorly and

gradually converging behind, the disc a little flattened in the middle before the base and slightly

depressed on either side anteriorly, the surface densely and minutely punctured; elytra subparallel in

their basal half, densely and minutely punctured, and with one or two raised lines on the disc, the piceous

colour at the base occupying less, at the apex more, than half of the elytral width; beneath densely and

minutely punctured, testaceous, the venter suffused with piceous; legs comparatively short and stout,

entirely testaceous, the claws only slightly dilated at the base.

Length 63-74 millim. (¢ 9.)

Hab. British Honpuras (Blancaneaur) ; Honpvuras, Ruatan I., Bay of Honduras

(Gaumer).

Two examples. ‘This species is not very closely allied to any other here enumerated:

the densely and very finely punctured surface, short silky pubescence, long thorax,

short, rather stout legs, and almost simple claws, chiefly distinguish it. The above

description is chiefly taken from the female specimen from Ruatan I.; the smaller,

male, example is immature, and has the sides of the thorax and of the elytra barely

darker than the rest of the surface. The apical joint of the maxillary palpi is

subcultriform. Copidita simplex, Waterh., from St. Bartholomew I., is a closely

allied species, and differs from O. tropicalis in having the thorax emarginate at the

middle of the base, and entirely flavous, and the sides of the elytra very broadly

marked with black; it apparently has the mandibles entire, as in O. tropicalis.

15. Oxacis nitidicollis, (Tab. VII. fig. 16, ¢.)

Elongate, clothed with rather coarse ashy pubescence; the head and prothorax shining, flavo- or reddish-

testaceous; the scutellum testaceous; the elytra opaque, brownish-violaceous with the suture and two

Head finely and rather closely punctured, the eyes and the tips of the mandibles piceous; antenne

piceous-brown, or testaceous with the apex of each joint darker, rather stout, joints 1-3 about equal in

length, 11 constricted at the middle; prothorax longer than broad, the sides moderately rounded anteriorly

and converging behind, the dise depressed in the middle before the base, and with a rather large rounded

depression on each side anteriorly, the base slightly emarginate in the centre, the surface finely and closely

punctured ; elytra densely punctured, and with two slightly raised lines on the dise; beneath densely and

finely punctured, testaceous or reddish-testaceous, the venter a little darker; legs piceous with the basal

two-thirds of the femora testaceous, or testaceous with the tarsi and the apices of the femora and tibiz

piceous-brown.

Length 73-83 millim. (¢ @.)

Hab. Mexico, Oaxaca (Hége).

Two examples. This species is allied to O. pallida, Lec., but differs from it in the

shining, less densely punctured, and unicolorous head and thorax, finer pubescence, &c.

The above description, except as regards colour, is chiefly taken from the dark-coloured

female example; the unique male appears to have the head and thorax abnormally

formed, the latter being not so long as broad, and having the discoidal impressions

deeper than in the female, and the former longitudinally grooved between the eyes.

16. Oxacis angustata.

Very elongate, narrow, finely pubescent; the head and prothorax slightly shining, piceous-brown, the former in

front, at the base, and at the sides behind, and the latter with an indeterminate longitudinal space on

either side of the disc, testaceous; the elytra opaque, piceous-brown, the suture a little lighter. Head

densely and finely punctured, the eyes black ; antennex piceous-brown, very long in the male, much shorter

in the female, joints 1-3 about equal in length, 11 constricted at the middle; prothorax longer than broad,

the sides moderately rounded anteriorly and gradually converging behind, the disc depressed in the middle

before the base and with a rather large but shallow oblique depression on each side anteriorly, the base

and apex feebly emarginate in the centre, the surface densely and finely punctured ; elytra very elongate,

subparallel, densely and finely punctured, and with three raised lines on the disc; beneath piceous-brown,

densely and finely punctured; legs piceous-brown, the basal two-thirds of the. femora and the coxe

testaceous.

Length 83-10 millim. (¢ 2.)

Hab. Mexico, Tehuacan (/ége).

One female and three male examples. This is a very elongate, natrow, moderate-

sized, obscurely-coloured species not very closely allied to any other here enumerated,

except O. variegata and the following, O. lineatula. The more finely punctured

surface, less opaque elytra, the lines on which are more distinctly raised, and different

colour distinguish it from any of the varieties of 0. cana. The apical joint of the

maxillary palpi is cultriform, its apical side much longer than the inner side.

17. Oxacis lineatula. (Tab. VII. fig. 17, ¢.)

Elongate, narrow, finely pubescent, slightly shining; pale brown or brownish-testaceous, the head in the middle,

the disc and sides of the prothorax, and the sides of the elytra broadly (and sometimes the suture on

either side for a short distance below the scutellum), fuscous or piceous-brown. Head densely and finely

punctured, the eyes and the tips of the mandibles black ; antenne brown or piceous-brown, with the two

«basal joints (and sometimes the extreme apex of the others) testaceous, very long in the male, shorter in

the female, joints 1 and 3 about equal in length, 11 constricted at the middle; prothorax longer than

broad, the sides moderately rounded anteriorly and converging behind, the disc depressed in the middle

before the base and with an oblique depression (very deep in some examples, quite shallow in others) on

either side anteriorly, the base and apex slightly emarginate in the middle, the surface densely and finely

punctured ; elytra subparallel, very closely and finely punctured (the punctures quite separate from each

other), with two raised lines on the disc and the suture also a little raised, the raised lines and the suture

accompanied on either side by a more or less distinct row of very shallow, fine, oblong, fuscous impressions ;

beneath densely and finely punctured, testaceous, the sides and venter piceous-brown ; legs testaceous, the

tibiee usually darker.

Length 5-8 millim. (¢ @.)

Hab. Mexico, Tehuacan (Hége).

Many examples. ‘This is one of several.species of which we have only received

examples from Tehuacan in the State of Puebla. 0. lineatula is closely allied to and

resembles an abraded example of O. angustata; but differs in its smaller size, less

elongate shape, and more shining, less densely punctured, and differently-coloured |

elytra. The raised lines and suture of the latter are accompanied on either side by fine

fuscous lines, formed by serially arranged very shallow oblong fuscous impressions.

Acapulco, Chilpancingo, Iguala, Oaxaca (Hége), Cuernavaca, Guanajuato, Leon, Sante-

comapan, Vera Cruz (Sad/é), Atoyac in Vera Cruz (H. H. Smith).

This is an exceedingly variable species in size and in the colour of the upper and

under surfaces, legs, and antenne; and some of its varieties are quite inseparable from

the numerous Texan examples before me. O. cana may be known from the allied

forms by its very elongate shape, finely and densely punctured head and thorax, densely

scabrous-punctate elytra, and very fine short ashy pubescence. In fresh examples the

pubescence on the front of the head and on each side of the disc of the thorax appears

to be thicker, and has the appearance of being transversely or obliquely combed. The

thorax usually has a median vitta, and the sides at the middle piceous or brownish (the

median vitta being sometimes quite obsolete, and the lateral marking conspicuous),

bat is sometimes entirely testaceous ; in some specimens there is a narrow smooth space

or raised line on the middle of the disc and, rarely, a minute bare space at the inner

limit of the lateral marking. The elytra are brownish or fuscous, sometimes with a

violaceous tinge, with the suture, and often the lateral margin also, testaceous; in rare

examples they are entirely testaceous.

The following varieties are connected with the typical form by numerous grada-

tions :—

In the Sallé collection the typical form is labelled Nacerdes chevrolati, Dej.; the

var. B, Oxacis sericea, Dugés; and the var. y, Oxacis concolor, Dugés. The typical

‘form and the var. 6 are about equally common in Mexico; the var. « was collected in

some numbers at San Gerdnimo, and one specimen of it has been received from Atoyac.

The species is still more variable in Mexico and Guatemala than in the Southern

United States. The antennz have the eleventh joint very strongly constricted at the

middle in both sexes (apparently, but not really, twelve-jointed), and the third joint

about as long as the first. Our specimens vary in length from 5-10 millimetres. We

figure a male example of the var. 6, and another of the same sex of var. a, the former

from Cuernavaca, and the latter from San Gerénimo.

19. Oxacis plumbea.

Very elongate, narrow, opaque, leaden-black (the elytra when denuded of pubescence with a violaceous tint in

certain lights), thickly clothed with fine ashy pubescence. Head (including the epistoma and labrum)

densely and finely punctured, the eyes not very coarsely granulated; antenne black, the first joint rather

longer than the third, the eleventh strongly constricted at the middle; prothorax convex, longer than

broad, the sides rounded anteriorly, constricted at the middle, and thence to the base subparallel, the disc

canaliculate behind, the base and apex with prominent margin and slightly emarginate in the centre, the

surface densely, very finely, and uniformly punctured; elytra scabrous-punctate, and without distinct

raised lines; beneath densely and finely punctured, piceous; legs piceous, the tibie a little lighter in one

example.

Two examples, apparently male and female. This insect is allied to, and of almost

the same colour as, the var. y of 0. cana; but differs from it in the less coarsely

granulated eyes and in the finer punctuation of the head and thorax, the pubescence

on the latter still finer and less dense. The unicolorous plumbeous colour, elongate

shape, and densely and very finely punctured surface distinguish this species from the

other allied forms.

median vitta and the sides, more or less, fuscous or piceous; the elytra piceous-brown or piceous

(with an eneous lustre when denuded of pubescence), with the suture, and sometimes the lateral

margin also, pale flavous or pale testaceous. Head densely and finely punctured, the eyes and the tips of

the mandibles black or piceous; antenne testaceous or fusco-testaceous, joint 1 a little longer than 3,

to O. cana, but differing from that species in the coarser and longer pubescence, less

scabrous elytra, more finely punctured thorax, the latter more gradually narrowed

from the middle to the base, &c. In its coarse pubescence the present insect

approaches 0. sericea, Horn, from California, and O. pallida, Lec., from Texas. ‘The

closely and finely punctured, the epistoma, and often a narrow space along the middle, smoother, the tips

of the mandibles, the eyes, and the palpi (usually) black ; antenne black, or black with the outer four or

five joints testaceous, or testaceous with joints 1-3 piceous, the third joint the length of the first, the

eleventh strongly constricted at the middle; prothorax convex, much longer than broad, the sides very

Eight examples from Mexico and one from Nicaragua, the latter agreeing perfectly

with the others. Closely allied to and much resembling some of the varieties of

O. cana; the thorax, however, is more regularly convex, more strongly rounded at the

sides anteriorly, and has the lateral spot placed near the anterior angles, instead of at

or near the middle as in 0. cana. The thorax is similarly marked in all the examples

before me, and the insect shows very little tendency to variation. An allied undescribed

species from Venezuela is known to me. A specimen from Presidio is figured.

An example of a species of this genus captured by Dr. O. Thiéme in July 1877 along

the line of the Panama railroad, and kindly given us by Dr. Sharp, agrees very nearly

with the description of Hypasclera schistacea, Kirsch ; it differs, however, in some minor

details and in being smaller in size. The unicolorous pale blue colour (which is much

obscured by the dense ashy pubescence) and testaceous legs distinguish this species from

the other allied forms. It is perhaps advisable to give a description of the Panama

insect :—

Elongate, narrow, subopaque, above and beneath pale ceruleous, densely clothed with fine ashy pubescence.

Head densely and minutely punctured, the labrum and the greater part of the mandibles testaceous, the

apices of the latter and the eyes black, the mandibles sharply pointed at the apex; palpi piceous, the last

joint of the maxillary pair elongate-triangular and with its inner side rather longer than the apical side ;

antenne (3) very long, joint 1 about as long as 3, 11 strongly constricted at the middle, fusco-testaceous,

the basal joint testaceous ; prothorax much longer than broad, as wide as the head, rather convex, the sides

a little rounded anteriorly and gradually converging from before the middle to the base, the disc canali-

culate in the centre behind and with a shallow oblique depression on either side anteriorly, the surface

quite so finely punctured as, above, densely clothed with coarse pubescence; legs brownish and thickly

pubescent ; tarsi with joints 1-4 of the front and intermediate pairs and 2 and 3 of the hind pair spongy-

tomentose beneath, the claws simple.

Length 84-14 millim. (¢ 92.)

Hab. Mexico, Tehuacan in Puebla (Hége).

Found in abundance by Herr Hége. This very distinct species differs from all the

allied forms in the colour and pubescence of the upper surface being variegate. The

pubescence is so close as to hide the dense and minute punctuation. ‘The thorax is

rather abruptly dilated on each side before the middle, the dilated portion strongly

rounded. ‘The tarsi have not only the penultimate joint tomentose beneath, but also

one or two of the joints preceding it. The mandibles are entire and rather broad at

the apex. The last joint of the maxillary palpi is elongate, and has its inner and apical

sides about equal in length, and the inner angle somewhat rounded. The species is

allied to O. angustata, but differs from it in having an additional number of tarsal joints

tomentose beneath and in the form of the maxillary palpi; it most certainly cannot be

separated from it generically.

PIRAS.

Last joint of the maxillary palpi broad, ovate, with the apex very obliquely truncate, that of the labial palpi

narrow, oblong ovate, with the apex abruptly rounded; mandibles entire at the apex, the right mandible

only with a short tooth on the upper inner side towards the tip ; mentum transverse; head prolonged into

a broad beak in front, not very deeply sunk into, and narrower than, the prothorax; labrum large,

subquadrate, and nearly as long as broad; eyes oblong, lateral, depressed, rather large, finely granulated,

very slightly sinuate on their inner edge; antenns inserted near the eyes, moderately long, 11-jointed,

1 longer than, 2 about one-third of the length of, 3, the following joints slightly decreasing in length,

11 sinuate at the middle; prothorax long and cylindrical; elytra about one-half broader than the

prothorax, moderately long, parallel to beyond the middle, and narrowing thence to the apex, the apices

rounded together ; legs moderately slender, the femora not dilated in the male; tibize each with two long

spurs ; penultimate joint of the tarsi rather broadly lobed; claws toothed.

This genus includes two species from the Pacific coast—one from Mexico and one

from Guatemala. Piras is allied to Rhinoplatia and Probosca, the former containing

one representative in California, and the latter several species in the middle or south of

EKurope*. It differs from the former in the much less prolonged head and toothed

claws, and in the antenne being inserted much nearer the eyes; and from the latter in

its longer and more exserted head, more ovate, oblong, and less emarginate eyes, broad

apical joint of the maxillary palpi, longer basal joint of the antenne, and toothed claws.

The species of all three genera appear to be chiefly found on the coast.

1. Piras nasalis. (Tab. VII. figg. 24, ¢@ ; 24a, labium; 246, maxilla and

maxillary palpus. )

Elongate, moderately shining, thickly clothed with rather long appressed ashy pubescence; the head and

prothorax dark bronze, the latter with a greenish or bluish lustre, the former with the mandibles (except

at the tip) and the anterior part of the epistoma testaceous; the elytra metallic blue. Head very closely

and finely punctured, the anterior part of the epistoma quite smooth, the palpi and antenne piceous or

piceous-brown; prothorax much longer than broad, cylindrical, as wide at the apex as at the base, the

sides feebly sinuate behind the middle, the basal and apical margins prominent, the base feebly emarginate

in the centre, the disc shallowly transversely depressed in the middle behind, and very shallowly obliquely

depressed on each side anteriorly, the surface very closely and finely punctured, a narrow longitudinal

space down the middle of the disc impunctate ; elytra nearly two and a half times as long as the prothorax,

densely, finely, and roughly punctured, and sometimes with indications of two fine raised lines on the disc ;

beneath bluish-black, the hind margins of the ventral segments sometimes paler, densely punctured; legs

roughly punctured and thickly and coarsely pubescent, piceous or piceous-brown; fifth ventral segment

unemarginate in both sexes; sixth ventral segment narrow, and with the lateral lobes slender, curved,

and setose, in the male.

Length 6-7 millim. (¢ 9.)

Hab. Guatemaua, Champerico (Champion).

Four examples of this species were captured by myself on the sea-shore at

Champerico.

2. Piras bicolor. (Tab. VII. fig. 25.)

Elongate, moderately shining, thickly clothed with ashy pubescence; the head blackish-bronze, the anterior

part of the epistoma and the mandibles (except at the tip) flavous; the prothorax orange-yellow; the

scutellum and elytra brassy-green. Head closely and finely punctured, the palpi and antenne piceous ;

prothorax much longer than broad, cylindrical, as broad at the apex as at the base, the sides very feebly

sinuate behind the middle, the disc feebly depressed in the centre before the base, and with the usual

depression on either side anteriorly quite small and almost obsolete, the base feebly emarginate in the

middle and with a rather prominent margin, the surface closely and finely punctured towards the sides

and more sparsely so on the disc (the punctuation much more diffuse here than upon the head); elytra

about three times as long as the prothorax, densely, finely, and roughly punctured, and with two fine

raised lines on the disc; beneath dark greenish-bronze, the prothorax orange-yellow, densely punctured ;

legs (including the coxe) testaceous, the tarsi and the apices of the tibie darker, finely punctured and

pubescent.

Length 54 millim.

Hab. Mexico, Mazatlan (Hoge).

One example only. This species differs from P. nasalis in its very different. colour ;

the head and thorax are narrower, and the legs are more finely pubescent and less

roughly punctured.

166 HETEROMERA.

Fam. XYLOPHILIDZ.

We follow Thomson (Skand. Col. vi. p. 367) in referring Xylophilus and the genera

formed at its expense to a separate family. The form of the abdomen and tarsi is very

different from that of the Pedilide or Anthicide, with one or the other of which they

are associated by most authors. The first and second ventral segments of the abdomen

are connate and immovable, a character noticed by Thomson, but overlooked by other

writers: Lacordaire, Mulsant and Rey, Jacquelin-Duval, and Leconte and Horn all

include Xylophilus in groups stated to possess five (distinct or free) segments, exclusive

of the short and sometimes visible sixth. The antepenultimate joint of the tarsi * is

produced beneath into a long and rather broad lobe, which extends beneath the small

penultimate joint to beyond the base of the apical one, the lobe itself being feebly

emarginate at the apex. These two characters, apart from others to be derived from

the shape of the head, &c., at once distinguish this family from all others of the

Heteromera {. Many authors place Xylophilus and Scraptia in the same group or

family; but these genera are not closely allied, though they have the head very

similarly formed.

Sixty-two species of this genus have been described; of these, twenty-three are from

Europe, five from Algeria, six from Japan, three from Ceylon, and sixteen from the

United States of North America. No less than thirty-six are here recorded from

Central America, and the genus will probably prove to be equally numerous in species

in the northern parts of South America; no American species has hitherto been

described from south of Texas or Florida. Of these thirty-six species, most of which

are exceedingly distinct, and not at all closely allied, nearly two thirds (twenty-two)

are represented by single examples only, and at least double this number must inhabit

Central America.

Not a single representative of the genus is contained in either of the very extensive

Mexican collections of M. Sallé or Herr Hoge; and the only specimens of Mexican

AXylophili we possess are a few recently captured by Mr. H. H. Smith. The general

XYLOPHILUS. 167

rarity of these insects is well known: they require special working for, and are not

often obtained by chance collecting. So far as my own observations go, they are, in

Central America, chiefly found in oak-woods, at elevations of from 3000 to 8000 feet ;

a considerable number of those collected by myself were beaten from the decaying

branches of oaks. The numerous genera and subgenera that have been proposed by

various authors are based solely upon European species, some of them upon single

species only, and upon slight differences in the form of the antenne or eyes. ‘Three of |

these, Phytobenus, Euglenes, and Aderus, have better claims than the others. These

differences, however, are of specific rather than generic value. Huglenes and Phytobenus

are not represented in Central America, but are replaced by other groups or subgenera

of equal value, of which X. flabellatus and X. lacertosus may be taken as typical

examples. The eyes in the Central-American species vary greatly in size (sometimes

reaching the base of the head, sometimes distant from it), in the extent of the emar-

gination (from very deeply emarginate to entire), and in the amount of pilosity (from

densely pubescent to apparently bare *). The antenne also vary considerably : in the

males of some species they are flabellate, or have a long apical joint; in others the

intermediate joints are transverse in the female; one, X. tantillus, has the second and

third. joints very short and subequal. The hind femora are often incrassate or clavate

in both sexes, sometimes incrassate in the male and slender in the female. The sexual

distinctions existing in many species in the form of the tibiz, femora, eyes, or antenne

are very remarkable; and in this respect Xylophilus is one of the most interesting

genera of the whole of the Heteromera. The peculiar pouch-like excavation of the

hind femora of the males of X. fragilis, X. unifasciatus, X. sericeus, and X. bicolor,

and the excavate, ciliate, and broadly dilated hind femora of the males of X. lacer-

tosus, X. forticornis, &c., are especially noteworthy.

In some of the Central- and North-American species the general shape is more

elongate and Anthiciform, and in these the sexual distinctions are less marked. All

are very fragile and difficult to obtain in perfect condition.

The earlier stages of many Xylophili are, no doubt, passed in rotten wood, especially

in that of various species of oak. :

The following table will assist in the identification of the Central - American

species :—

the suture very narrowly castaneous; the upper surface thickly clothed with rather long, somewhat

coarse, decumbent pubescence, the pubescence variegate (yellowish on the light-coloured parts and darker

elsewhere) and on the prothorax forming two irregular stripes on the disc and a marginal fringe at the

sides behind (the hairs longer here and almost forming atuft). Head large and broad, densely and roughly

punctured ; eyes (¢) hairy, very coarsely granulated, exceedingly large, occupying the whole of the

lateral portion of the head (viewed from behind the head appears to be very narrowly and subangularly

extended on either side beneath them), contiguous, very deeply emarginate; antenne (¢ ) extending

quite to the end of the elytra, rather slender, joint 1 stout, 2 transverse, stout, 3 nearly four times as

to the apex, 4-10 in great part (the rami excepted) testaceous, the rest more or less piceous, all the

joints (the rami included) thickly clothed with long fine hairs; prothorax moderately convex, much

narrower than the head, about as long as broad, the sides converging from the middle, almost straight at

the base, the disc obsoletely canaliculate, the surface very densely and finely punctured; elytra long,

very much wider than the prothorax, parallel, flattened on the disc, and with a broad and rather deep

oblique depression extending from the shoulders downwards towards the suture, the suture also depressed

at the base, the surface rather shining, densely and coarsely punctured, the punctures finer at the extreme

base; legs (including the tarsi) comparatively very elongate, the hind femora incrassate, piceous, the four

anterior tibiee beneath and the bases of the femora lighter, the tarsi and the knees (narrowly) testaceous

or fusco-testaceous; the tibiee almost straight, the hind pair only a little curved at the base, the front

pair with a short tooth on the inner side at the apex.

Length 34 millim. (d.)

Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith).

Two male examples of this exceedingly distinct species were captured by Mr. Smith

during his expedition to Western Mexico. X. flabellatus and the following five species

belong to the same section of the genus as the North-American X. melsheimeri, Lec.

The fringe of long hairs at the sides of the thorax behind extend to the shoulders of

the elytra, and resemble, at first sight, acute hind angles. In this and the allied species

the dark parts of the elytra are apparently almost bare; but when examined under a

strong lens, the dark pubescence is easily seen. The eyes are clothed with short, fine

erect hairs. The pattern of the elytra is different from that of X. melshewmeri.

2. Xylophilus ramosus.

Moderately elongate, parallel; head black; prothorax reddish-testaceous; elytra brownish-yellow, with an

interrupted fascia just below the base, a longitudinal extension of which runs some distance down the

suture, a broad, much interrupted fascia about the middle (formed by four partly confluent longitudinal

streaks on each elytron), and a very narrow transverse streak near the suture some distance before the

apex, piceous, the base and shoulders and the narrow dividing spaces of the median band brown; the pube-

scence long, that on the light parts ashy in tint. Head moderately large, densely and roughly punctured,

and with a smooth central line on the vertex; eyes (¢ ) hairy, very large, moderately coarsely granulated,

narrowly separated, very deeply emarginate ; antenne (<¢ ) reaching to beyond the middle of the elytra,

hairy, joint 3 nearly four times as long as 2, 4 barely half the length of 3, 4-10 gradually increasing in

length, and each with an exceedingly long and slender ramus, 11 about three times as long as 10, much

thickened beyond the middle, and then abruptly constricted and narrow to the apex, all the joints testa-

ceous, 1, the apical half of 11, and the tips of the rami slightly infuscate ; prothorax moderately convex,

narrower than the head, about as long as broad, the sides converging from the middle, straight behind,

the surface densely and finely punctured; elytra long, very much wider than the prothorax, parallel, a

little flattened on the disc, and with a broad oblique depression extending from the shoulders downwards

towards the suture, the suture also depressed at the base, the surface slightly shining, densely and

coarsely punctured, the punctures finer at the extreme base; legs long and slender, the hind femora

incrassate, testaceous, the hind femora towards the apex and the hind tibie infuscate, the tarsi flavous.

Length 3 millim. (¢.)

Hab. GUATEMALA, Quiche Mountains 8000 feet (Champion).

One male example. Smaller and less elongate than X. /labellatus; the antennze

considerably shorter and much paler in colour; the head smaller; the eyes not so

large, more finely granulated, and separated by a narrow space on the vertex (in

X. flabellatus they are contiguous); the thorax and elytra differently coloured; the

legs and palpi in great part testaceous.

8. Xylophilus sticticus. (Tab. VIII. fig. 2, ¢.)

Moderately elongate, parallel ; head black; prothorax reddish-brown, the disc stained with piceous; elytra

brownish-yellow, with an interrupted fascia immediately below the base, a longitudinal extension of

which runs some distance down the suture, an angulated fascia a little below the middle (connected with

basal one along the lateral margin and with three longitudinal branches extending upwards on the disc of

each elytron), and a transverse streak near the suture some distance before the apex, piceous, the shoulders

and the space in front of the basal fascia brown ; the pubescence long, that on the light parts of the elytra

ashy. Head large and broad, densely and roughly punctured; eyes (¢') hairy, very coarsely granulated,

exceedingly large, occupying the whole of the lateral portion of the head (the head very narrowly

extended behind them), contiguous, very deeply emarginate ; antennse ( ¢ ) reaching to beyond the middle

of the elytra, hairy, entirely testaceous, joint 3 about three and a half times as long as 2, 4 not half the length

of 3, 4-10 gradually increasing in length, and each with an exceedingly long and slender ramus, 11 about

three times as long as 10, much thickened beyond the middle and then abruptly constricted and narrow

to the apex ; prothorax moderately convex, much narrower than the head, about as long as broad, the

sides converging from the middle, straight behind, the surface densely and finely punctured; elytra

moderately long, parallel, very much wider than the prothorax, a little flattened on the disc, and with an

oblique depression extending from the shoulders downwards towards the suture, the suture also depressed

at the base, the surface densely and coarsely punctured, the punctures finer at the extreme base; legs

moderately long, the four anterior femora rather stout, the hind femora strongly incrassate, fusco-testa-

ceous, the hind femora and tibia much stained with piceous, the anterior tibia with a short tooth on the .

inner side at the apex.

Length 3 millim. (¢.)

Hab. Guatema.a, San Gerénimo (Champion).

One male example. Closely allied to X. ramosus, but differing from it in its less

elongate shape, shorter and stouter legs, much broader head, and larger, more coarsely

granulated, and contiguous eyes. The markings of the elytra and the form and colour

of the antenne are very similar in both species. The eyes are contiguous in the males

of X. flabellatus and X. sticticus, distinctly separated in the same sex of X. ramosus.

4. Xylophilus amule. (Tab. VIII. fig. 3, 2.)

Moderately elongate, parallel; head black ; prothorax reddish-brown, the disc stained with piceous; elytra

castaneous, with a small quadrangular patch on either side of the suture below the base, a short oblong

patch a little below this on the outer portion of the disc, an elongate patch below and in a line with this,

connected on its inner side with an elongate streak, and a common angulate fascia some distance before

the apex (not reaching the lateral margin), black, a narrow, angulate, transverse space before and behind

the anteapical fascia, an oblique space just below the first sublateral spot, and the shoulders (indetermi-

nately) brownish-yellow ; the pubescence long and variegate. Head moderately large, ensely and roughly

punctured ; eyes (2) clothed with short, erect, pubescence, coarsely granulated, large, occupying almost

the whole of the side of the head (the head very narrowly extended on either side behind them), rather

narrowly separated, very deeply emarginate; antenne ( @ ) testaceous, slightly infuscate at the base, about

reaching to the basal third of the elytra, moderately stout, thickening a little outwardly, joint 2 short and

globose, 3 more slender than, and nearly twice as long as, 2, 4—10 decreasing gradually in length, 9 and

10 as broad as long, 11 about twice as long as, and very much stouter than, 10, abruptly and obliquely

constricted beyond the middle, and with the apical portion slender; prothorax about as long as broad,

not very convex, narrower than the head, the sides obliquely converging from the middle, straight behind,

the surface densely and finely punctured ; elytra moderately long, parallel, rather broad, a little flattened

on the disc, and with a rather deep oblique depression extending from the shoulders downwards towards

the suture, the suture also depressed at the base, the surface slightly shining, densely and coarsely punc-

tured ; legs (2 ) moderately long, the hind femora incrassate, reddish-testaceous, the basal half of all the

tibize and the hind femora beyond the middle piceous, the tarsi flavo-testaceous.

Length 2? millim. (9.)

Hab. Mexico, Amula in Guerrero 6000 feet (1. H. Smith).

One female example. This elegant insect, the male of which doubtless has flabellate

antennee, is perhaps nearest allied to X. ramosus. ‘The less coarsely granulated eyes

distinguish it from X. flabellatus and X. sticticus; the legs are formed as in the latter,

but are less elongate than in the former. The pattern of the elytra is quite different

from that of these three species, and the insect cannot possibly be the other sex of one

of them.

5. Xylophilus trifasciatus. (Tab. VIII. tig. 4, 2.)

Rather short, parallel ; head black ; prothorax piceous, with the base and apex narrowly reddish-brown, or

reddish-brown and more or less suffused with piceous; elytra brownish-testaceous, with two angulated

fascize, one near the base and another below the middle, connected along the suture and at the sides,.

and a narrower subangulated fascia some distance before the apex, black or piceous—in some exam-

ples the fascize are broken up into spots, and do not reach the suture, in others the piceous colour is more’

extended ; the pubescence long, that on the elytral fasci# ashy. Head large, densely and roughly punc-

tured; eyes hairy—in the male exceedingly large, occupying the whole of the lateral portion of the

head (the head very narrowly extended behind them), very coarsely granulated, deeply emarginate

—in the female smaller, separated by a space about equalling half the diameter of the eyes as seen

from above, rather more finely granulated, and less deeply emarginate (the head a little more broadly

extended on either side behind them); antennz hairy—( ¢) reaching to beyond the middle of the elytra,

rather slender, joint 2 short and globose, 3 about three times as long as 2, 4 not half the length of 3,

4-10 very distinctly increasing in length, and each with an exceedingly long and slender ramus, 11

nearly three times as long as 10, much thickened beyond the middle, and then abruptly constricted and

slender to the apex, 1 and 2, the rami in great part (the tip only of the lower one), and 11 (except at the

base) piceous, the rest testaceous—( 9 )- reaching to about the basal fourth of the elytra, stouter,

widening outwardly, joint 3 about twice as long as 2, 4 shorter than 3, 4—8 almost equal in length, 9 and

- 10 a little shorter, 11 twice as long as, and much stouter than, 10, very obliquely truncate at the apex, the

apex pointed, 1 and 2 and 10 and 11 piceous or infuscate, the rest testaceous ; prothorax about as long

as broad, not very convex, narrower than the head, the sides converging from the middle, straight behind,

the surface densely and finely punctured ; elytra short, parallel, rather convex, with a shallow oblique

depression extending from the shoulders downwards, the suture also depressed at the base, the surface

densely and coarsely punctured ; legs moderately long, reddish- or fusco-testaceous, the four anterior

femora darker outwardly, the hind femora and hind tibie more or less piceous, all the tarsi flavo-testa-

ceous ; the hind femora strongly incrassate in the male, moderately so in the female.

Length 2-24 millim. (d 2.)

¥72 HETEROMERA.

Hab. Guatemaua, San Gerénimo (Champion); Panama, Bugaba, Volcan de Chiriqui

3000 feet, Boquete 3500 feet, David (Champion).

Numerous examples of both sexes, collected by myself at various elevations, from a

little above the sea-level up to 3500 feet. ‘The smaller size, the rather more convex and

less elongate shape, the differently coloured antenne, the third joint of which is rela-

tively shorter in the male, and the different system of coloration of the elytra distin-

guish X. trifasciatus from X. sticticus or X. ramosus. The elytra vary a little in the

markings, according to the predominance of the lighter or of the darker colour ; in some

specimens the fasciz are broken up into spots; the apex in all is testaceous. Chiriqui

examples do not differ from those from Vera Paz. Among the Central-American species

with flabellate antenne in the male, this seems to come nearest to the North-American

X. melsheimeri, Lec., but to differ from it in its much smaller size, less elongate shape,

and differently coloured antenne.

6. Xylophilus breviramus. (Tab. VIII. figg. 5, ¢; 6, 2.)

Of the same form and colour as X. trifasciatus; the elytra similarly marked, but with the extreme apex

usually piceous. Head large, densely and roughly punctured ; eyes very large and coarsely granulated

(as in X. érifasciatus)—in the male narrowly separated (not contiguous), in the female divided by a space

only twice the width of that of the male (this space narrower than that of the female of X. trifasciatus) ;

antenne—( ¢') shorter than in X. trifasciatus, joint 2 short and globose, 3 three times as long as 2, 4 about

half the length of 3, 4-10 subequal, and each with a comparatively short clubbed ramus (the longest

only about equalling joints 7-9 united), 11 very stout, twice as long as 10, abruptly constricted beyond

the middle, and then slender to the apex, 1, 10, and 11 and the tips of the outer rami piceous, the rest

testaceous—( ) much as in X. trifasciatus, joints 4-10 gradually decreasing in length and increasing in

width, 1 and 9-11 (except the tip of the latter) piceous, the rest testaceous; prothorax, elytra, and legs

as in X. trifasciatus ; the hind femora strongly incrassate in both sexes.

Length 2-23 millim. (¢ 9.)

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

Three male and two female examples. Very closely allied to X. trifasciatus, but

easily distinguished from it in the male sex by the different proportions of the antennal

joints, the rami of which are much shorter and more clubbed, and the less con-

tiguous eyes. The female is only to be separated from the corresponding sex of

X. trifasciatus by the rather more approximate eyes and the differently coloured

antenne. ‘The antennal rami are shorter and more clubbed than in any of the pre-

ceding species. The extreme apices of the elytra are more or less infuscate in four

examples, the fifth having the apices testaceous as in X. trifasciatus. While the eyes

in the male are less contiguous than in X. trifasciatus, the reverse is the case in

the female, the intraocular space being comparatively narrow in this sex of X. drew-

ramus. ‘Though apparently collected in company with X. trifasciatus in two localities,

there can be no doubt of its specific distinctness.

Moderately elongate, subparallel, broad, very robust, opaque, very densely clothed with rather long, semierect

pubescence ; the head and prothorax black or brownish-black, the former more or less ferruginous in

front, and the latter, in one example, indeterminately lighter at the sides; the elytra reddish- or piceous-

brown, or piceous with the base and shoulders brownish, with a rather broad, blackish stripe on either side

of the suture extending from the base to far beyond the middle, this stripe limited posteriorly by a

common triangular, ashy-pubescent, fusco-testaceous subapical patch, from which a line of ashy

pubescence runs up the suture, and another (but interruptedly) along the outer edge of the sutural stripe,

a similar streak of ashy pubescence extending from the shoulders downwards, and more or less confluent

with the triangular patch. Head large and broad, very densely and roughly punctured ; eyes very hairy,

moderately large, narrowly separated in the male, more distant in the female, coarsely granulated, deeply

emarginate, the head in both sexes somewhat broadly extended on either side behind them and rounded

externally ; antenne ferruginous, the apical joint usually darker, very hairy, in both sexes exceedingly

stout from the base—( ¢ ) very long, widening a little outwardly, joint 2 more than half the length of,

and a little stouter than, 3, 3-8 much longer than broad, subequal, 9 and 10 a little shorter, 10 as

broad as long, 11 fully three and a half times as long as 10, slightly curved—{ @ ) shorter, more widened

outwardly, the apical joint ovate, nearly twice as long as the tenth ; prothorax narrower than the head,

rather convex, as long as broad (a little longer in the male than in the female), the sides rounded and

narrowing in front and almost straight behind, the surface punctured like that of the head ; elytra broad,

parallel to about the middle, with a broad, shallow, oblique depression extending from the shoulders

downwards, the suture also depressed at the base, the surface densely, coarsely, and rather shallowly

punctured ; legs densely pubescent, moderately long, reddish-testaceous, the apical halves of the tibie

(and sometimes the femora in the middle) piceous, the tarsi flavo-testaceous ; the four anterior tibie

inner side at the apex in the male, the hind pair with a matted tuft of coarse fulvous hairs at the outer

apical angle in the female ; the femora rather slender, the hind pair in the male very broadly widened,

grooved on their inner side, and the concavity filled with a dense row of short fulvous hairs.

Length 3-34 millim. (3 9.)

Had. Guatemata, San Lucas Toliman 5000 feet, San Gerdnimo 3000 feet (Champion).

One male and three female examples. The large size, robust build, exceedingly

stout antennee, the apical joint of which is very elongate and subcylindrical in the male,

peculiar elytral markings, &c., distinguish this remarkable species from all others of

the genus here enumerated. In the excavate and densely ciliate inner margin of the

hind femora in the male it resembles the following, X. forticornis. The four anterior

tibiee are sinuously curved in both sexes, very strongly so in the male, the hind pair

having a thick tuft of fulvous hairs at the outer apical angle in the female. ‘The apical

joint of the antenne is ovate in the female and elongate and a little curved in the

male. This is one of a group of species somewhat numerously represented in Central

America, and, like the following, possesses very peculiar sexual characters.

8. Xylophilus forticornis. (Tab. VIII. figg. 8, ¢ ; 8a, hind leg.)

Rather short, subparallel, broad, robust, opaque, very densely clothed with rather long, semierect, silky pube-

scence ; the head and prothorax brownish-black, or ferruginous much stained with piceous, the anterior

part of the head always ferruginous ; the elytra brownish- or fusco-testaceous, with a broad, ill-defined

piceous-brown fascia before, and a rather narrower one below the middle, the pubescence between and

beyond these fasciz yellowish or ashy, and forming a more or less distinct transverse median band and

an apical patch (this latter sometimes showing a tendency to form a common triangular spot just below

174 | HETEROMERA.

the second fascia), which are connected along the suture by a line of similar pubescence. Head large and

broad, very densely and finely punctured; eyes very hairy, large, contiguous in the male, narrowly sepa-

rated in the female, coarsely granulated, deeply emarginate, the head in both sexes somewhat broadly

extended on either side behind them and rounded externally ; antenne piceous or fusco-ferruginous, with

the apical joint and one or more of the basal ones ferruginous, sometimes in great part ferruginous, densely

pubescent, in both sexes exceedingly stout—(¢ ) moderately long, widening a little outwardly, joint 2

more than half the length of 3, 3-9 about equal in length, 9 and 10a little shorter, 11 three times as long

as 10, slightly curved—(¢) shorter, more thickened outwardly, joints 8-10 transverse, 11 about twice

the length of 10, ovate ; prothorax narrower than the head, rather convex, as long as broad (a little longer

in the male than in the female), the sides rounded and converging in front, straight behind, the surface

punctured like that of the head ; elytra broad, parallel to about the middle, with a very shallow oblique

depression (sometimes obsolete) extending from the shoulders downwards, the surface densely, coarsely,

and rather shallowly punctured ; legs densely pubescent, moderately long, reddish- or fusco-testaceous,

the tarsi paler; the four anterior tibie sinuously curved in both sexes, strongly so in the male, the front

and middle pairs with a long sharp tooth on the inner side at the apex in the male, the hind pair with

a matted spine-like tuft of fulvous hairs at the outer apical angle in the female; the femora rather slender,

the hind pair in the male very broadly widened, grooved on their inner edge, and the concavity filled

with a row of short fulvous hairs.

Length 23-22 millim. (3 9.)

Hab. Panama, Bugaba, Volcan de Chiriqui 3000 feet (Champion).

Six examples, three of each sex. Smaller than X. lacertosus; the eyes contiguous

in the male, more narrowly separated in the female ; the elytra differently marked, the

ashy pubescence forming transverse bands instead of longitudinal streaks; the legs

almost unicolorous reddish-testaceous. The sexual characters are very similar.

9. Xylophilus humeralis. (Tab. VIII. fig. 9, ¢.)

Moderately elongate, parallel, broad, robust, opaque, very thickly clothed with rather long, fine, semierect pube-

scence; black, the shoulders of the elytra reddish or testaceous, the pubescence along the edge of the suture

ashy, and a longitudinal stripe of similarly-coloured pubescence running down from the humeral spot. Head

very large in the male, a little smaller in the female, densely and roughly punctured; eyes very hairy—

exceedingly large, coarsely granulated, and contiguous in the male, smaller, more finely granulated, and

narrowly separated in the female,—deeply emarginate, the head in both sexes extended on either side

behind them, but more broadly so in the female, and rounded externally ; antenne entirely black, densely

clothed with long pubescence, exceedingly stout in both sexes—(¢) long, extending to far beyond the

middle of the elytra, filiform, joint 2 a little shorter than 3, 3 considerably shorter than 4, 4-10 much

longer than broad, and about equal in length, 11 two a half times as long as 10, slightly curved—( ? )

much shorter, widening outwardly, joint 2 a little shorter than 3, 3 as long as 4, 5-8 gradually wider,

9 and 10 transverse, 11 ovate and nearly twice as long as 10; prothorax rather convex, narrower than the

head, as long as broad, the sides rounded and converging in front, straight behind, the surface punctured

like that of the head ; elytra nearly twice as wide as the prothorax, parallel to about the middle, densely

and coarsely punctured ; legs moderately long, piceous, the outer joints of the tarsi more or less testaceous ,

the four anterior tibie sinuously curved in the male, feebly so in the female, the front pair with a sharp

tooth on the inner side at the apex in the male, the hind pair with a matted spine-like tuft of fulvous hairs

at the outer apical angle in the female; the femora rather slender (the hind legs in the male broken off).

Length 3 millim. (¢ 2.)

Hab. Panama, Volcan de Chiriqui 3000 feet (Champion).

One specimen only of each sex. In this species the antenne are even stouter than

in X. lacertosus &c.; these organs are very long in the male (longer than in the same

XYLOPHILUS. 175

sex of Y. Jacertosus) and in the female are much shorter and still more thickened

outwardly. The unique male example is unfortunately imperfect, the hind Jegs being

missing. The only Central-American species nearly allied to it is the following.

10. Xylophilus curvipes. (Tab. VIII. figg. 10, ¢; 10a, hind leg.)

Moderately elongate, parallel, robust, opaque, very thickly clothed with rather long, fine, semierect pubescence ;

black, the base of the elytra fulvo-testaceous, the rest of the elytra uniformly clothed with greyish

pubescence. Head large, densely and roughly punctured; eyes (¢) hairy, very large, approximate,

coarsely granulated, deeply emarginate, the head extended on either side behind them and rounded

externally ; palpi piceous ; antenne ( ¢) black, the apical joint ferruginous at the tip, densely pubescent,

very stout, extending to beyond the middle of the elytra, filiform, joint 2 only a little shorter than 3,

3-8 about equal in length, 9 and 10 transverse, 11 fully three times as long as 10, slightly curved ; pro-

thorax narrower than the head, rather convex, as long as broad, the sides rounded and converging in

front, straight behind, the surface punctured like that of the head; elytra parallel in their basal half,

moderately broad, densely and coarsely punctured ; legs ( ¢ ) moderately long, rather slender, piceous, the

knees and the base of the femora reddish-testaceous, the tarsi (except the apical half of the first joint of

the hind pair) flavo-testaceous ; the hind femora broadly widened, grooved on the inner side, the concavity

filled with short fulvous hairs; the tibiee a little curved, the intermediate pair strongly so without, and

abruptly sinuate within, the anterior pair furnished on the inner side at the apex with a long sharp spur.

Length 23 millim. (¢.)

Hab. Guatemata, San Gerénimo (Champion).

One male example. Smaller and narrower than X. humeralis; the antenne shorter

and not nearly so stout in the male (the third joint not shorter than the fourth and the

penultimate joints transverse); the elytra with the entire base fulvous, and for the rest

uniformly pubescent (without trace of a sublateral greyish-pubescent stripe). The

usual oblique depression on each elytron is scarcely indicated.

Leconte’s brief description of X. basalis, from Illinois, agrees in many respects with

this insect. In X. basalis, however, the ninth and tenth joints of the antenne are

longer (transverse in X. curvipes) and the eleventh is shorter (as long as the two

preceding united in X. basalis, nearly as long as the three preceding in X. curvipes);

the palpi are rufous (piceous in XY. curvipes); and the elytra, apparently, have the base

more broadly fulvous. Leconte’s type of X. basalis had all the legs broken off; but

from the form of the antenne it was no doubt a male.

11. Xylophilus flavitarsis. (Tab. VIII. fig. 11, ¢.)

Rather short, subparallel, comparatively broad and robust, opaque, thickly clothed with fine, semierect pubescence;

black, the pubescence along the edge of the suture from the apex nearly to the base ashy, a transverse

band of similarly-coloured pubescence (not reaching the suture, and becoming wider outwardly and

extending to the lateral margin) at about the middle of the elytra, the pubescence at the sides of the pro-

thorax also ashy in tint. Head moderately large, densely and finely punctured; eyes (9) hairy, rather

large, coarsely granulated, deeply emarginate, separated by a space about equalling half the diameter of

the eyes as seen from above, the head broadly extended on either side behind them and rounded externally ;

antenne (9 ) black, the apical joint ferruginous at the tip, densely pubescent, exceedingly stout, widening

outwardly, reaching a little beyond the middle of the elytra, joints 2 and 3 subequal, 3-7 longer than

broad, 8 as broad as long, 9 and 10 transverse, 11 ovate and nearly twice as long as 10; prothorax

narrower than the head, rather convex, as long as broad, the sides rounded and converging in front,

176 HETEROMERA.

straight behind, the surface punctured like that of the head ; elytra nearly twice as wide as the pro-

thorax, parallel to about the middle, densely and coarsely punctured, with a shallow oblique depression

extending from the shoulders downwards ; legs ( 2 ) moderately long, rather slender (the femora included),

black, the tarsi entirely flavo-testaceous, the tibie almost straight, the hind pair with a matted spine-like

tuft of fulvous hairs at the outer apical angle.

Length 23 millim. ( 9.)

Hab. Guatemaua, Cerro Zunil 4000 feet (Champion).

Two examples, both females; the male doubtless has the hind femora incrassate.

Allied to X. humeralis, but smaller and shorter; the elytra black, with a transverse

median band (not reaching the suture) of ashy pubescence, the suture also clothed

with similarly-coloured pubescence ; the tarsi entirely flavo-testaceous.

12. Xylophilus v-notatus. (Tab. VIII. fig. 12, 2.)

Moderately elongate, subparallel, rather broad and robust, opaque, thickly clothed with fine, semierect

pubescence; brownish-black, the elytra each with a long narrow V-shaped mark (forming together a

perfect W) of whitish silky pubescence towards the suture about the middle, this mark connected internally

with a similarly-coloured streak of pubescence extending along the suture and externally with a large sub-

triangular lateral patch (the latter extended along the lateral margin to the apex), the base narrowly and the

apex more broadly clothed with whitish pubescence, for the rest clothed with dark brownish pubescence, the

prothorax also with whitish pubescence at the sides. Head moderately large, densely and finely punctured ;

eyes ( 2 ) hairy, rather large, coarsely granulated, deeply emarginate, narrowly separated, the head broadly

extended on either side behind them and rounded externally ; antenne ( ? ) piceo-ferruginous, the apical

three joints darker, densely pubescent, about reaching the middle of the elytra, exceedingly stout, widening

outwardly, joints 2 and 3 subequal, 4 a little longer than 3, 4-10 gradually becoming shorter and wider,

7 and 8 about as broad as long, 9 and 10 transverse, 10 strongly so, 11 a little narrower than, and nearly

twice as long as, 10, short, ovate; prothorax narrower than the head, rather convex, as long as broad, the

sides rounded and converging in front, straight behind, the surface punctured like that of the head ; elytra

.about twice as wide as the prothorax, parallel in their basal half, with an oblique depression extending

from the shoulders downwards, densely and coarsely punctured; legs ( 2 ) moderately long, rather slender

(the femora included), piceous, the four anterior femora fusco-ferruginous, the tarsi entirely testaceous,

the tibie almost straight, the hind pair with a matted spine-like tuft of fulvous hairs at the outer apical

angle.

Length 2? millim. ( 2.)

Hab. Guatemata, Cerro Zunil 4000 feet (Champion).

One female example only of this very distinct species was obtained. Allied tp

X. fiavitarsis ; but larger and rather more elongate, the elytra with a very acutely

angulated median fascia of silky whitish pubescence and the apex and lateral margins

also clothed with similarly-coloured pubescence. The North-American X. nedulosus,

Lec., seems to be an allied species; but it differs from X. v-notatus in having the

base of the elytra reddish-brown.

13. Xylophilus 2

Hab. Guatemata, San Gerénimo (Champion).

A single female example of a species closely allied to X. flavitarsis and X. v-notatus,

the head of which is unfortunately missing. The insect is blackish-brown in colour;

XYLOPHILUS. . 177

the elytra with an ashy-pubescent, testaceous, common, triangular patch towards the

apex (much as in X. lacertosus) and a transverse median band of ashy pubescence, the

latter connected externally with a stripe of similarly-coloured pubescence which extends

from the base to the apex. The hind tibia have a matted spine-like tuft of fulvous

hairs at the outer apical angle as in the female of X. flavitarsis.

14. Xylophilus laticeps.

Moderately elongate, convex, black, shining, thickly clothed with long, semierect, ashy pubescence. Head very

large and broad, thickly and not very finely punctured ; eyes ( ¢) very hairy, coarsely granulated, very

deeply emarginate, large, somewhat widely separated, the head rather broadly and subangularly extended

on either side behind them; palpi piceous; antenne (¢) very pubescent, moderately long, stout, black,

the tip of the last joint ferruginous, joint 2 rather more than half the length of 3, 3-10 about equal in

length, longer than broad, 5-10 scarcely differing in width, 11 a little stouter and much longer than 10,

ovate, acuminate; prothorax convex, much narrower than the head, nearly as long as broad, the sides

rounded and converging in front, almost straight behind, the surface thickly and somewhat coarsely

punctured ; elytra rather short, much wider than the prothorax, convex, somewhat rounded at the sides,

widest a little below the base, thickly and rather coarsely punctured ; legs ( ¢ ) stout, brownish-black, the

tarsi fusco-testaceous, the hind femora moderately clavate, the anterior tibize curved without, sinuous

within, and with a short tooth on the inner side at the apex.

Length 2-24 millim. (¢.)

Hab. Mexico, Teapa in Tabasco (H. H. Smith) ; Guatemata, El Reposo 800 feet

(Champion).

Two examples from the Pacific slope of Guatemala and one from the Atlantic slope

of Southern Mexico, all males. These differ from the same sex of the following

similarly-coloured species in their very large and broad head, somewhat widely-separated

eyes, and stout antenne. ‘The head is rather broadly and somewhat angularly extended

on either side behind the eyes.

15. Xylophilus atricolor.

Rather short, convex, black, shining, thickly clothed with long, semierect, ashy pubescence. Head moderately

large, finely and not very closely punctured; eyes very hairy, coarsely granulated, large, deeply emarginate,

narrowly separated in the male, more distant in the female, the head narrowly extended on either side

behind them and with slightly prominent hind angles ; palpi testaceous; antenne very pubescent, rather

slender, black, the last joint ferruginous at the tip—( ¢) moderately long, joint 2 considerably shorter

than 3, 3-10 increasing a little in width but about equal in length, longer than broad, 11 stouter than, and

more than twice as long as, 10, ovate, acuminate—( Q ) much shorter, joints 6-10 transverse ; prothorax

convex, a little narrower than the head, about as long as broad, the sides rounded and converging in front,

nearly straight behind, the surface thickly and somewhat coarsely punctured, the disc obsoletely canali-

culate behind ; elytra convex, rather short, at the base about one half broader than the prothorax, a little

rounded at the sides, widest at the middle, thickly and rather coarsely punctured ; legs stout, black, the

tarsi entirely flavo-testaceous, the hind femora moderately clavate in both sexes; the anterior tibie on

the outer side curved to beyond the middle and then abruptly bent inwards, on the inner side a little

sinuate and at the apex furnished with a sharp tooth, in the male.

Length 13-2 millim. (¢ Q.)

Hab. Panama, Bugaba (Champion).

Two examples. ‘The more slender antenne, narrower head, more approximate eyes,

and strongly-bowed anterior tibie distinguish the male of X. atricolor from the same

sex of X. laticeps. The palpi and tarsi are entirely testaceous. ‘The sexual differences

in the form of the antenne are similar to those of X. cinctipennis and X. equinoctialis.

16. Xylophilus funereus.

Moderately elongate, rather broad, convex, subparallel, black, shining, thickly clothed with long, semierect, ashy

pubescence. Head moderately large, closely and finely punctured ; eyes (¢ ) very hairy, large, somewhat

narrowly separated, moderately emarginate, not very coarsely granulated, the head narrowly extended

on either side behind them and with rather prominent hind angles; palpi piceous-brown; antenne (<¢)

moderately long, rather slender, black, joint 2 a little shorter than 3, 3-10 increasing a little in width,

10 about as broad as long, 11 stouter than, and about twice as long as, 10, ovate, acuminate ; prothorax a

little broader than long, not much narrower than the head, the sides rounded and narrowing in front,

almost straight behind, the surface thickly and somewhat coarsely punctured; elytra convex, much broader

than the prothorax, moderately long, subparallel in their basal half, very shallowly obliquely depressed

on either side at the base, thickly and rather coarsely punctured; legs ( ¢) rather long, black, the apical

joints of the tarsi testaceous, the hind femora moderately clavate, the anterior tibiz feebly sinuous within

and with a short tooth at the inner apical angle.

Length 23-23 millim. (¢.)

Hab. Guatemata, Quiche Mountains 8000 feet, Cerro Zunil 4000 feet, Chiacam

(Champion).

One male example from each locality. More parallel, more elongate, and larger

than the same sex of X. atricolor; the eyes a little more widely separated, the apical

joint of the antenne shorter, the tarsi and palpi darker, the anterior tibiee very feebly

curved and with the tooth at the inner apical angle shorter and finer. ‘The slender

antenne and much narrower head distinguish it from X. laticeps. The Quiche

specimen is immature, and has the basal joints of the antenne and the front tibie

fusco-testaceous. X. ater, Lec., from Texas, is probably a close ally of this species;

Leconte’s description is, however, too brief for identification, the form of the head and

legs not being mentioned.

17. Xylophilus flavicornis.

Rather short, subparallel, black, shining, thickly clothed with long, semierect, ashy pubescence. Head thickly

and finely punctured; eyes (2) hairy, very large, very coarsely granulated, rather narrowly separated,

feebly emarginate, the head very narrowly extended on either side behind them; palpi testaceous;

antenns ( 2 ) moderately slender, short, testaceous, the basal joint infuscate, joint 2 globose, a little shorter

than 3, 3 longer than 4, 4-10 transverse, 11 stouter than, and more than twice as long as, 10, ovate,

acuminate ; prothorax convex, narrower than the head, about as long as broad, the sides rounded and

converging in front, almost straight behind, the surface thickly and somewhat coarsely punctured ; elytra

much wider than the prothorax, rather short, subparallel in their basal half, thickly and coarsely punc-

tured ; legs rather short, testaceous, the hind femora infuscate and moderately incrassate.

Length 14 millim. (9.)

Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith).

One female example. The much smaller size and the testaceous antenne and legs

(the hind femora excepted) distinguish X. flavicornis from X. atricolor and X. funereus.

XYLOPHILUS. 179

The eyes are very coarsely granulated, the head very narrowly extended on either side

behind them :

Rather short, convex, shining, thickly clothed with long, semierect, ashy pubescence ; black, the elytra each with

two large testaceous spots, one at the shoulder and the other near the apex, the latter not quite reaching

the suture (in one example still larger and extending to the apex). Head large and broad, thickly and

somewhat coarsely punctured ; eyes (3) very hairy, deeply emarginate, very coarsely granulated, large,

narrowly separated, the head narrowly extended on either side behind them and with rather prominent

slightly curved without, sinuous within, and with a short tooth on the inner side at the apex.

Length 2 millim. (¢.)

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

Three male examples. Less parallel and more convex than X. cinctipennis, black,

the elytra with a large testaceous spot at the shoulder and another near the apex. The

pubescence is long, semierect, and rather coarse. The hind femora in the male are

much thickened and somewhat angularly dilated on the outer side beyond the middle,

the inner side being slightly sinuate.

19. Xylophilus cinctipennis.

Moderately elongate, subparallel, shining, thickly clothed with long, semierect, ashy pubescence ; the head and

prothorax black, the latter sometimes reddish ; the elytra testaceous, with a transverse more or less curved.

black or piceous fascia on either side at the middle, the fascia not reaching the suture and extending

180 HETEROMERA.

Hab. Mexico, Teapa in Tabasco (H. H. Smith); Guatemaua, San Joaquin and San

Gerénimo in Vera Paz, Volcan de Atitlan (Champion); Nicaracua, Chontales (Janson).

Two male and four female examples. A small shining species, with black head and

thorax and testaceous elytra, the latter with a transverse curved black median fascia on

either side; the pubescence is long, semierect, and rather coarse, and does not hide the

punctuation ; the eyes are very coarsely granulated, large, and hairy; the hind femora

are clavate in both sexes ; the anterior tibie in the male are slightly sinuate within and

somewhat hooked at the tip.

20. Xylophilus chiriquensis. (Tab. VIII. fig. 14, 3.)

Closely allied to X. cinctipennis and differing as follows :—The antenne rather more elongate, black, the apical

joint fusco-ferruginous; the median fascia of the elytra larger and broader, nearly reaching the suture

but not continued upwards along the lateral margin; the anterior tibie ( ¢ ) curved to beyond the middle

and then abruptly bent inwards, the inner edge sinuate, at the middle almost angulate, and furnished

with a long sharp tooth at the apex.

Length 23 millim. (¢.)

Hab. Panama, Volcan de Chiriqui 3000 feet (Champion).

One male example. This insect is extremely closely allied to X. cinctipennis, but

the form of the male anterior tibie is very different. In our two males of X. cincti-

pennis the anterior tibie are feebly curved without, sinuous within, and the tooth on

the inner side at the apex is fine and short; in the male of X. chiriquensis the anterior

tibie are very abruptly bent inwards a little beyond the middle, and the tooth at the

apex is longer and stouter.

21. Xylophilus xquinoctialis. (Tab. VIII. fig. 15, ¢.)

Short and rather broad, subovate, shining, thickly clothed with long, semierect, ashy pubescence ; the head

black ; the :prothorax reddish- or piceo-testaceous; the elytra testaceous or flavo-testaceous, with a

black or piceous median fascia, the fascia nearly or quite reaching the suture, widened towards the lateral

margin, and of variable width (in some specimens divided in the middle, in others narrow and sub-

XYLOPHILUS, 181

Hab. Mexico, Atoyac and Teapa (H. H. Smith); Guatemata, Cahabon, San Ger6-

nimo, Zapote (Champion); Panama, Volcan de Chiriqui and David (Champion).

Var, The prothorax and elytra piceous-brown, the latter with the base testaceous (9 ).

Hab. Guatemata, Cahabon (Champion).

Var, The prothorax piceous-brown; the median fascia of the elytra very broad and connected with a large

triangular scutellar patch (¢).

Hab. Panama, Tolé (Champion).

Numerous examples of both sexes of the type, a single worn example of each variety.

Apparently a widely-distributed and not uncommon species in Central America.

Allied to X. cinctipennis, but much smaller and much less elongate; the antenne are

entirely testaceous, and exhibit similar sexual differences, the apical joint, however, is

proportionately stouter in the male; the head is similarly shaped, and the eyes are very

hairy and very coarsely granulated; the thorax is broader than long; the elytra are

much shorter and a little rounded at the sides, and have a similar median fascia; the

hind femora are incrassate in both sexes; the anterior tibie in the male are similarly

shaped. In an immature female example from San Gerénimo the head is fusco-

testaceous and scarcely darker in colour than the thorax.

22. Xylophilus sexmaculatus. (Tab. VIII. fig. 16, 3.)

Moderately elongate, rather broad, shining, clothed with fine decumbent pubescence; the head black; the

prothorax reddish-testaceous; the scutellum piceous; the elytra testaceous, with a black spot at the

shoulders and two others at the middle (an oblong one on the centre of the disc and an oblique one

between this and the lateral margin) and a narrow infuscate fascia immediately before the apex. Head

moderately large, finely and somewhat closely punctured; eyes ( ¢) hairy, rather large, somewhat widely

separated, not very coarsely granulated, deeply emarginate, the head somewhat broadly extended on

either side behind them and with rather prominent hind angles ; palpi testaceous ; antennz ( ¢ ) testaceous,

long and slender, joint 2 short and globose, shorter than 3, 3-10 differing very little in length but

gradually becoming a little stouter, rather elongate, 11 twice as long as, and stouter than, 10, ovate, acumi-

nate; prothorax broader than long, narrower than the head, obsoletely canaliculate, the sides very

gradually converging from the base, rounded in front, the base grooved within in the middle, the surface

densely and somewhat coarsely punctured (more closely and more coarsely so than the head); elytra

rather broad, much wider than the prothorax, widest at the middle, with an oblique depression extending

from the shoulders downwards, the suture also depressed at the base, the sides almost straight in front,

the surface closely and somewhat coarsely punctured (the punctuation less dense but not coarser than that

of the prothorax); legs( ¢) entirely testaceous, rather long and slender, the hind femora slightly clavate,

the anterior tibie abruptly bent inwards at the middle and furnished with a sharp tooth on the inner

side at the apex, the four hinder tibize very slightly sinuous.

Length 2 millim. (<¢.)

Hab. Guatemata, Cerro Zunil 4000 feet (Champion).

One male example. This is one of several species of Xylophilus of which specimens

were obtained by myself in the vicinity of the coffee-estate of “Las Nubes,” on the

Pacific slope. In X. sewmaculatus the hind femora are not excavate on their inner

to about the middle. Several of the preceding species are closely allied to it.

23. Xylophilus fragilis, (Tab. VIII. figg. 17,4; 17a, hind leg.)

Moderately elongate, narrow, subparallel, finely pubescent, shining ; fusco-testaceous, the eyes black ; the elytra

flavo-testaceous, with a fuscous lateral patch (gradually shading off into the ground-colour) about the

middle and the suture very narrowly infuscate towards the apex. Head moderately large, finely and

closely punctured; eyes (¢) pubescent, large, occupying the whole of the side of the head (the head very

narrowly extended behind them), deeply emarginate, somewhat coarsely granulated, narrowly separated ;

antenne ( ¢ ) long and slender, testaceous, joint 2 globose, about half the length of 3, 3-10 elongate, 3

longer than 4, 6-8 each as long as 3, 9 and 10 a little shorter and broader, obovate, 11 wider than, and

nearly twice as long as, 10, ovate, acuminate ; prothorax broader than long, narrower than the head,

rather convex, subquadrate, the sides a little rounded and converging in front, the surface punctured

like that of the head, the disc with a smooth raised line in the middle at the base and transversely

depressed on either side of this; elytra rather long, parallel in their basal half, each with an oblique

depression below the shoulder, the suture also depressed at the base, the surface finely and closely punc-

tured (the punctuation not so dense but a little coarser than that of the prothorax); beneath piceous-

brown ; legs ( ¢ ) long and quite slender (including the femora), testaceous; the hind femora not stouter

than the others, excavate along their lower edge, the part of the femur on either side of this extended

tibiee scarcely curved.

Length 13 milliim. (<¢.)

Hab. Gvuatemata, San Lucas Toliman 5000 feet ( Champion).

One example, from the oak-woods in the vicinity of the Lake of Atitlan. Narrower,

smaller, and more parallel than X. sermaculatus ;.the upper surface, legs, and antenne

testaceous; the eyes black; the antenne and legs long and quite slender; the elytra

with an indeterminate fuscous lateral patch. The very peculiar form of the hind

femora of the male is a striking character in this insect: a somewhat similar structure

is to be found in Uroplatopsis appendiculata, a species of Lagriide.

24. Xylophilus bicolor. (Tab. VIII. fig. 18, ¢ .)

Short and rather broad, finely pubescent, shining; the head and prothorax fusco-testaceous, the eyes black ;

the scutellum and elytra black, the latter with the base rather broadly flavo-testaceous, this colour not

quite extending to the suture. Head comparatively small, finely and closely punctured; eyes (3)

pubescent, rather small, finely granulated, deeply emarginate, widely separated, the head narrowly

extended on either side behind them and with somewhat prominent hind angles; antenne ( ¢ ) short,

slender, thickening outwardly, testaceous, joint 2 globose, stout, 3 slender, one third longer than 2,

4-6 each shorter than 3, subequal, 7-10 stouter and gradually becoming shorter, 10 not much longer

than broad, 11 stouter than, and about twice as long as, 10, ovate; prothorax rather convex, narrower

than the head, subquadrate, nearly as long as broad, narrowing a little in front, very closely punctured

(the punctuation somewhat coarser than that of the head); elytra broad, rather convex, widest about the

angularly dilated near the apex); the tibie almost straight.

Length 1§ millim. (<¢.)

XYLOPHILUS. 183

Hab. Mexico, Amula in Guerrero 6000 feet (H. H. Smith).

One male example. This peculiar little species is not very closely allied to any

other here described; the short and rather broad form, shining surface, comparatively

small head, small eyes, and peculiar coloration distinguish it easily. The usual oblique

post-humeral impression on the elytra is scarcely indicated. The hind femora are

grooved on the inner edge, somewhat as in the same sex of X. fragilis.

25. Xylophilus unifasciatus. (Tab. VIII. fig. 19, 3.)

Short and rather broad, opaque, clothed with fine silky appressed pubescence; the head black, the prothorax

ferruginous, the scutellum piceous, the elytra brownish-testaceous, with a rather narrow, transverse,

piceous band about the middle, this band extending to the lateral margin and continued along it to the

base. Head large and broad, densely and very finely punctured, very opaque; eyes (¢) large, slightly

pubescent, coarsely granulated, occupying the whole of the side of the head, the head not extended behind

them, widely separated (the intraocular space as broad as the diameter of the eye seen from above), not

very deeply emarginate ; antenne (3) short, slender, thickening outwardly, testaceous, joint 2 stouter

and a little shorter than 3, 3 and 4 equal in length, 5-10 gradually increasing in width, 10 about as long

as broad, 11 twice as long as, and broader than, 10, ovate, acuminate ; prothorax considerably narrower than

the head, rather convex, nearly as long as broad, the sides straight behind and rounded and converging in

front, the surface very opaque and punctured like that of the head; elytra broad, widest at the middle,

feebly transversely depressed below the base, the sides straight in front, the surface finely, densely, and

shallowly punctured (the punctuation a little coarser than that of the prothorax); beneath, the prothorax

excepted, piceous; legs (¢) moderately long, testaceous; the femora rather slender, the hind pair

very little stouter than the others and grooved on the inner edge, the part of the femur on either side of

this a little extended and piceous in colour; all the tibie slender and almost straight.

Length 2 millim. (¢.)

Hab. Muxico, Teapa in Tabasco (H. H. Smith).

One male example. In this small species the head and thorax are scabrous; the

former is cut off behind in a line with the hinder portion of the eyes (the head being

not at all extended behind them), very broad, and opaque; the eyes are large and very

widely separated; the elytra are not so dull as the head and thorax, and have a

transverse fascia at the middle extending completely across. In the form of the hind

femora in the male it approaches X. dzcolor.

26. Xylophilus inflatus. (Tab. VIII. fig. 20, ¢.)

Short and broad, convex, finely pubescent ; the head black, opaque; the prothorax fusco-ferruginous, opaque ;

the scutellum black; the elytra black, with the base broadly, a large oblique spot a little below the middle

(not quite reaching the suture and distant from the lateral margin), and the apices brownish-testaceous.

Head large and broad, densely punctured ; eyes( 4) slightly pubescent, rather coarsely granulated, large,

occupying the whole of the side of the head (the head not at all extended behind them), very widely

separated (the intraocular space considerably broader than the diameter of the eye seen from above),

somewhat feebly emarginate; antenne (¢ ) short, slender, widening a little outwardly, testaceous, joint 2

very little shorter than 3, 3 and 4 subequal, 5-10 very gradually increasing in width, 9 as broad as long,

10 transverse, 11 about twice as long as, anda little stouter than, 10, ovate ; prothorax at the base scarcely

narrower than the head, broader than long, rather convex, the sides converging almost from the base,

the surface densely and finely punctured ; elytra about one half broader than the prothorax, comparatively

short and broad, widest about the middle, the sides a little rounded, the surface very closely and finely

punctured and without sutural or post-humeral depression ; beneath, the prothorax excepted, black ; legs

(dS) slender, rather short, testaceous ; the hind femora flattened and considerably wider than the others,

not excavate on the inner edge; the tibiw straight, the hind pair flattened and dilated from the base

to the apex.

Length 13 millim. (<¢.)

Hab. Mzxtco, Chilpancingo in Guerrero 4600 feet (H. H. Sinith).

One male example. In the form of the head and antenne this minute species

resembles X. unifasciatus. The hind femora and hind tibie are flattened and dilated,

the former simple and not excavate along their inner edge. The short, broad,

convex form and elytral markings distinguish it from all others of the genus here

enumerated.

X. ventricosus, Lec., has similarly inflated elytra.

27. Xylophilus laticollis.

Short and very broad, convex, finely and densely pubescent ; the head black, testaceous in front; the prothorax

and scutellum fusco-ferruginous ; the elytra obscure testaceous, with a broad brownish fascia before and

a narrower one beyond the middle, the pubescence on the light parts ashy in colour (forming three

transverse bands), that on the fascie sparser and darker. Head large and broad, densely punctured ;

eyes moderately large, pubescent, somewhat finely granulated, occupying the whole of the side of the

head and laterally projecting (the head not at all extended behind them), very widely separated, some-

what feebly emarginate; antenne short, slender, widening a little outwardly, testaceous, joint 2 stout

and moniliform, 3 much more slender and very little longer than 2, 3-5 about equal in length, 6-10

gradually becoming shorter and wider, 10 transverse, 11 stouter than, and about twice as long as, 10,

ovate, acuminate ; prothorax strongly transverse, fully as wide at the base as the head, narrowing almost

from the base, densely and finely punctured ; elytra comparatively short and broad, widest about the

middle, the sides a little rounded, the surface slightly shining, very closely and finely punctured, and

without sutural or post-humeral depression; beneath, the prothorax excepted, piceous; legs slender,

rather short, testaceous, the hind femora only a little stouter than the others, the tibiee almost straight.

Length 2 millim.

Hab. Mexico, Chilpancingo in Guerrero 4600 feet (H. H. Smith).

One example, apparently a female. .X. Jaticollis resembles X. unifasciatus and

X. inflatus in the shape of the head, and the eyes project in a similar manner. The

thorax is dull ferruginous and very strongly transverse; the elytra are even broader

than in X. inflatus, testaceous in colour, with a broad brownish fascia before and a

narrower one beyond the middle, the testaceous parts being densely clothed with ashy

pubescence ; the legs are short, slender, and testaceous, the hind femora very little

stouter than the others.

28. Xylophilus corticarioides.

Short and convex, obovate, piceous-black, the base of the elytra brownish, rather shining, the entire surface

uniformly clothed with fine, ashy, appressed pubescence. Head moderately large, closely and finely punc-

tured ; eyes small and prominent, entire, very widely separated, finely granulated, the head narrowly

extended on either side behind them and with rather prominent hind angles ; antenne short, very slender,

widening a little outwardly, testaceous, joint 2 about half the length of 1, 3 one and a half times the

length of 2, 4 shorter than 3, 4-7 elongate, subequal, 8-10 wider, 10 about as broad as long, 11 stouter

and much longer than 10, ovate, acuminate; prothorax about as long as broad, convex, narrower than

the head, the sides rounded and converging in front, almost straight behind, the surface punctured like

that of the head; elytra short and broad, widest about the middle, a little rounded at the sides, feebly

transversely depressed below the base, closely and finely punctured; beneath black, densely pubescent ;

legs very slender, moderately long, piceous-brown, the extreme base of the four hinder tibie, the anterior

tibie entirely, and the tarsi testaceous, the hind femora slender and only a little stouter than the

others.

Length 13 millim.

Hab. Panama, Los Remedios (Champion).

One example, of uncertain sex. X. corticarioides has somewhat the facies of a small

Corticaria; it is about the same size as X. sericeus, but has the head and antenne very

differently formed, the legs much more slender, and the elytra broader behind, the

general shape being obovate.

29. Xylophilus sericeus. (Tab. VIII. figg. 21,¢; 21a, hind leg.)

Short and broad, rather convex, piceous-brown, opaque, uniformly clothed with exceedingly fine, sericeous,

ashy, pruinose pubescence. Head large and broad, densely and minutely punctured ; eyes (¢) black,

pubescent, very large, occupying the whole of the side of the head (the head not at all extended behind

them), narrowly separated, coarsely granulated, deeply emarginate; antenne ( 3) very pubescent, long

and slender, filiform, extending to beyond the middle of the elytra, testaceous, joint 2 exceedingly short,

globose, not half the length of 3, 3 a little longer than 4, 4 shorter than 5, 5-10 elongate, becoming a

little shorter outwardly, 11 about twice as long as, and stouter than, 10, ovate, acuminate ; prothorax

convex, much narrower than the head, as long as broad, narrowing a little in front, the disc very finely

and obsoletely canaliculate, and with an oblique groove on either side, the grooves confluent just before

the base and together forming a U-shaped depression, the surface densely and exceedingly minutely

punctured (the punctuation only visible under a powerful lens); elytra rather short, comparatively convex,

very much broader than the prothorax, subparallel in their basal half, the surface densely and finely

punctured (the punctuation coarser than that of the prothorax), and without sutural or posthumeral

depression ; beneath coloured as above; legs slender and moderately long, testaceous ; the hind femora

(3) very little stouter than the others and deeply grooved on the inner edge, the part of the femur on

either side of this a little extended and densely fringed with short fulvous hairs; all the tibie moderately

curved.

Length 14 millim. (¢.)

Hab. Panama, Bugaba (Champion).

One male example. This minute species possesses a different facies from most of

the other Central-American members of the genus ; the upper surface is piceous-brown,

and uniformly clothed with exceedingly fine, silky, pruinose pubescence; the punctua-

tion of the head and thorax is very minute, and that of the elytra very fine; the

antenne are very pubescent, long and slender, with the second joint exceedingly short

and the apical joint longer and stouter than the tenth; the hind. femora (in the

male) are grooved on the inner edge and ciliate. In this last-mentioned character

X. sericeus approaches X. fragilis and X. unifasciatus.

30. Xylophilus femoralis, (Tab. VIII. figg. 22, ¢; 22a, hind leg; 224,

antenna.)

Oblong ovate, rather narrow, black, densely clothed with short, silky, appressed brownish pubescence, the

pubescence on the prothorax and on the base and apex of the elytra (the scutellar region excepted) whiter,

that of the under surface silvery-white, the prothorax opaque, the head and elytra (when denuded of

pubescence) shining. Head large, closely and finely punctured; eyes (¢) finely pubescent, very large,

occupying the whole of the side of the head (the head not extended behind them), narrowly separated,

rather coarsely granulated, moderately emarginate; palpi fusco-testaceous; antenne ( ¢) long and stout,

very pubescent, black, the two basal joints fusco-testaceous, joints 1-3 rather slender, 2 very short, not

half the length of 3, 3 and 4 about equal in length, 4-10 much wider than 3, flattened and subtriangular,

longer than broad, 11 stouter and about one third longer than 10, obliquely truncate at the apex; pro-

thorax convex, much narrower than the head, nearly as long as broad, rounded and narrowed at the sides

in front and a little narrowed behind, the disc with an oblique depression on each side a little before the

middle and a shorter and shallower one on either side near the base (the basal depressions nearer

together than the others), the surface closely and finely punctured ; elytra convex, at the base about one

half broader than the prothorax, a little rounded at the sides, widest at the middle, very shallowly trans-

versely depressed below the base, the surface closely and finely punctured; legs ( ¢ ) comparatively short,

black, the tarsi flavo-testaceous, the base of the tibize testaceous, the four anterior femora slender, the hind

femora exceedingly broad and stout, the anterior tibiz slightly hooked at the inner apical angle.

Length 13 millim. (¢.)

Hab. Guatemata, Zapote (Champion).

One male example. This insect may be known at once from the other unicolorous

black species here described by the short appressed silky pubescence and more opaque

surface. The antenne have their joints 4-10 subtriangular, broad, and somewhat

flattened. The thorax has four depressions, two on each side of the disc. The hind

femora ( 3 ) are exceedingly stout and broad, and have on the inner side at the middle

an indistinct tooth. The anterior tibie are scarcely more curved than the intermediate

pair.

31. Xylophilus argentatus. (Tab. VIII. fig. 23, ¢.)

Elongate, rather narrow, parallel, black, opaque, very densely clothed with fine,-scale-like, closely appressed,

bluish-white, submetallic pubescence; the labrum and oral organs piceous-brown ; the elytra each with a

very sharply defined, large, subtriangular, lateral patch a little below the middle, this patch deeply

triangularly excised behind, occupying about two-thirds of the width of each elytron as seen from above,

. and densely clothed with dark coppery-brown appressed pubescence. Head moderately large, closely and

minutely punctured; eyes (¢) comparatively small, very widely separated, finely granulated, feebly

emarginate, distant from the base of the head, the sides of the latter obliquely converging behind them ;

antenne ( ¢) slender, moderately long, subfiliform, piceous-brown, joint 2 short, rather more than half

the length of 3, 3-10 very gradually decreasing in length, 10 about as broad as long, 11 stouter and

considerably longer than 10, ovate, acuminate; prothorax about as long as broad, narrower than the head,

somewhat flattened on the disc, feebly dilated at the sides anteriorly (about as wide here as at the base),

and the sides behind this slightly compressed, the surface closely and minutely punctured ; elytra compa-

ratively very elongate, parallel, much wider than the prothorax, broadly and shallowly depressed below the

base, closely and finely punctured; beneath black, densely pubescent; legs (¢) long and quite slender

Length 24 millim. (¢.)

Hab. GuatEMALA, Quiche Mountains 8000 feet (Champion).

One male example. This remarkable insect is not closely allied to any other species

of the genus. The very dense, scale-like, bluish-white, almost silvery, pubescence

resembles that of certain Curculionide; the general shape is elongate and Anthiciform ;

XYLOPHILUS. 187

the pubescence (except on the elytral spots) is so dense as to completely hide the punc-

tuation ; the antenne are slender and subfiliform, with the second joint short and the

apical joint a little stouter and longer than the tenth; the legs are long and quite

slender, the hind femora neither dilated nor grooved and the front tibie not hooked

at the tip (in the male). The large lateral mark on the elytra is very sharply defined.

Narrower and more elongate than X. singularis, the antenne much shorter and more

filiform, the head somewhat similarly shaped.

Apparently allied to X. quercicola, Schwarz, from Florida.

32. Xylophilus singularis. (Tab. VIII. fig. 24, ¢.)

Moderately elongate, black, opaque, very densely clothed with fine, silky, closely appressed, bluish-white pubes-

cence; the labrum and oral organs testaceous ; the elytra each with a somewhat rounded, sharply defined

spot close to the suture at the base and a much larger one near the suture just below the middle, these

spots densely clothed with dark fulvous-brown pubescence. Head large and broad, sparsely and minutely

punctured ; eyes comparatively small, very widely separated, feebly emarginate, finely granulated, distant

from the base of the head, the sides of the latter obliquely converging behind them; antenne ( 3) long

and quite slender, the apical three joints somewhat abruptly larger, black, the two basal joints testaceous,

joint 1 comparatively elongate, as long as 2 and 3 united, 2 more than half the length of 3, 3-8 elongate

and subequal, 9 and 10 wider and subtriangular, each about as long as 8, 11 stouter and much longer

than 10, ovate, acuminate; prothorax about as long as broad, narrower than the head, somewhat flattened

on the disc, dilated at the sides before the middle and a little wider here than at the base, the sides com-

pressed behind this (viewed laterally, with a deep transverse groove extending from the flanks upwards),

the base feebly sinuate on either side, the surface closely and minutely punctured ; elytra rather short,

nearly twice as wide as the prothorax, widest at the middle, parallel in front, broadly transversely

depressed below the base, the space occupied by the basal spots a little raised, the surface very closely and

minutely punctured; beneath black, densely pubescent; legs very long and slender, black, the tarsi and

the anterior tibie fusco-testaceous; the hind femora ( ¢) slender, very little stouter than the others,

emarginate on the inner side some distance before the apex (appearing subangularly dilated*), and

grooved beneath ; the tibie almost straight.

Length 23 millim. (¢.)

Hab. Guatemata, San Lucas Toliman 5000 feet (Champion).

One male example. This is one of a group of species somewhat numerously repre-

sented in Central America, from the State of Panama to the Los Altos region of

Guatemala. X. singularis possesses a very different facies from any other member of

the genus: in the peculiar dense bluish-white submetallic pubescence it approaches

X. argentatus. The eyes are almost entire and distant from the base of the head ;

the antenne are very slender and elongate, and have the apical three joints stouter

than the rest ; the thorax is dilated in front and compressed at the sides; the legs are

very slender and elongate.

83. Xylophilus suturalis. (Tab. VIII. fig. 25.)

Elongate, parallel, moderately broad, black, densely clothed with fine pruinose pubescence, opaque (when

denuded of pubescence shining) ; the head brownish in front, with a triangular olivaceous patch at the base

(divided down the middle by a greyish line), for the rest grey; the prothorax with a sinuous olivaceous

band on either side of the disc (transversely connected a little behind the middle, confluent in front,

and extending inwards at the base), enclosing two narrow transverse greyish marks, and for the rest

grey; the scutellum grey; the elytra olivaceous, with a narrow well-defined sutural stripe, which is

widened towards the apex, and the shoulders and lateral margins, narrowly, bluish-grey. Head moderately

large, rather long, very closely and finely punctured, and with a smooth central line; eyes not very large,

prominent, distant from the base of the head (the head broadly extended behind them and rounded late-

rally), widely separated, rather deeply emarginate, finely granulated ; antenne rather short, moderately

stout, widening outwardly, piceous, the two basal joints and the apical one lighter, joint 2 short, half the

length of 3, 4 much shorter than 3, 4-10 subtriangular, gradually becoming shorter and wider, 9 and 10

broader than long, 11 stouter and much longer than 10, ovate, acuminate ; prothorax about as long as

broad, a little wider than the head, the sides dilated in front, somewhat compressed behind this, and thence

gradually converging to the base, the base feebly sinuate on either side, the disc obsoletely canaliculate

and with a transverse depression before the base, the surface densely and finely punctured ; elytra at the

base about one half broader than the prothorax, long, parallel, flattened on the disc and broadly and

shallowly transversely depressed below the base, closely and somewhat coarsely punctured, the space

occupied by the sutural stripe smoother; beneath blackish-brown, very densely clothed with greyish

pruinose pubescence ; legs long, moderately slender, blackish, the tarsi and the front tibiee lighter, densely

clothed with greyish pruinose pubescence, the hind femora simple, the tibie almost straight. .

Length 3 millim. .

Hab. Panama, Bugaba (Champion).

One specimen, probably a female. X. sutwralis is quite unlike any other species of

the genus known to me. In its elongate Anthiciform shape it approaches Y. argen-

tatus and X. anthicoides. The thorax is distinctly wider than the head, and broadest

in front; the antenne have their joints 4-10 subtriangular; the elytra are long and

parallel and flattened on the disc; the surface is covered with a pruinose pubescence,

which does not (as in X. argentatus) completely hide the punctuation. The peculiar

arrangement and colour of the pubescence on the elytra—the suture, lateral margins,

and shoulders being bluish-grey and the rest of the surface olivaceous—is very

characteristic.

34. Xylophilus anthicoides. (Tab. VIII. figg. 26, ¢; 26a, labium; 264,

Elongate, subparallel, black or dark brown (the humeri or sometimes the entire elytra paler), and shining when

denuded of pubescence, the latter exceedingly dense and closely appressed and variable in colour—usually

dark brown or coppery-brown, but sometimes lighter or even variegate, owing to an admixture of yellowish-

white pubescence; the head usually with the sides and a central line yellowish-white ; the prothorax

with a narrow sinuous line at the sides, enclosing a brown spot anteriorly, two small oblique spots in the

middle behind, and a median line in front whitish or yellowish-white; the scutellum whitish; the elytra

each with an oblique spot on the disc before the middle, the suture very narrowly in some specimens, the

lateral margins, and a large oblique H-shaped mark, confluent at the suture close to the apex, white or

yellowish-white (a line of this colour extending along the suture to the apex and there confluent with

the lateral stripe, thus enclosing an oblique patch, the oblique spot on the disc usually connected with

the lateral stripe). Head moderately large, with only a few scattered punctures (almost smooth when

denuded of pubescence); eyes (¢ @) small, distant from the base of the head, very widely separated,

feebly emarginate, finely granulated; antennew (¢ Q) thickly pubescent, rather short, varying in colour

from piceous-brown to testaceous, moderately slender, thickening outwardly, joint 2 short, rather more

than half the length of 3, 3-10 gradually decreasing in length and increasing in width, 10 as broad as

head, about as long as broad, the sides dilated in front, compressed behind this, and thence to the base

parallel or very slightly converging, the base feebly sinuate on either side, the disc with a short, deep,

oblique impression on each side near the base, the impressions confluent behind (in some specimens forming

a deep transverse pit, and filled with whitish pubescence), the surface closely and finely punctured ; elytra

long and subparallel, widest beyond the middle, about twice as wide as the prothorax, broadly transversely

depressed below the base, very closely and finely punctured; beneath black, densely pubescent; legs

varying in colour from piceous-brown to testaceous, long and slender, the tibie almost straight, the hind

femora simple (but a little stouter in the male than in the female); the hind tibie feebly dilated on the

inner side before the middle in the male.

Length 23-23 millim. (¢ 9.)

Hab. GUATEMALA, Quiche Mountains 7000 to 9000 feet (Champion).

Numerous examples of both sexes of this handsome species were beaten from the

branches of oak-trees on the mountain-slope above the village of Chimente, in the Los

Altos region of Guatemala. Allied to X. argentatus and X. suturalis, but differing

greatly from either. The species may be at once known from all others of the genus

by the elytra each having an oblique white or yellowish-white streak on the disc and a

large similarly-coloured oblique H-shaped mark near the apex, the inner portion of

the latter curved inwards behind and confluent with the corresponding portion of the

one on the opposite elytron at the suture. In one female specimen the brownish

pubescence of the elytra is paler and the white marks are edged with dark brown.

The colour of the legs and antenne is variable, as is also that of the darker portion of

the elytral pubescence. The eyes are almost entire. In one abraded, apparently

immature, example the head and thorax are quite black, the elytra, legs, and antenne

are testaceous, and the head is shining, smooth, and almost impunctate.

A. anthicoides much resembles an Anthicus.

35. Xylophilus stigmosus. (Tab. VIII. fig. 27.)

Broad, rather short, opaque, brownish-testaceous, densely clothed with fine, silky, closely appressed pubescence ;

the head, except in front, piceous-brown, the eyes black; the prothorax with a narrowly separated reddish-

brown triangular patch on each side of the middle of the disc, for the rest clothed with whitish pubes-

cence ; the scutellum whitish; the elytra with a rather large oblong dark brown spot on either side of

the suture at the base and a broad similarly-coloured zigzag fascia just below the middle (extending

nearly to the lateral margin), for the rest clothed with whitish pubescence. Head large and broad, finely

and rather sparsely punctured ; eyes small and prominent, entire, rather finely granulated, very widely

separated, distant from the base of the head, the sides of the latter obliquely converging behind them ;

antenne testaceous, clothed with long hairs, long and slender, the apical three joints stouter, joint 2

stouter and only a little shorter than 3, 3-8 elongate and subequal, 9 and 10 wider, much longer than

broad, 11 longer and stouter than 10, ovate, acuminate ; prothorax broader than long, a little narrower

than the head, somewhat flattened on the disc, the sides dilated in front, compressed behind this, and

thence to the base almost straight, the‘base feebly sinuate on either side, the surface closely and finely

punctured; elytra at the base about one half broader than the prothorax, gradually widening to beyond

the middle, the sides a little rounded behind but straight in front, broadly transversely depressed below

the base, closely and finely punctured ; beneath piceous-brown, densely pubescent; legs long and slender,

fusco-testaceous, the hind femora little darker, the tibie almost straight.

Length 14 millim.

190 HETEROMERA.

One example, probably a female. This small species has the eyes quite unemarginate

and distant from the base of the head, and in this respect it resembles an Anthicus (the

eyes, however, are transverse, and not oval asin Anthicus); the thorax is broader than

long and a little dilated at the sides in front; the antenne are long and slender, with

the second joint very little shorter than the third and the apical three joints stouter

than the preceding ones; the elytra are comparatively broad and short, widened from

the base to beyond the middle, and have a spot on either side of the suture at the base

and broad zigzag fascia just beyond the middle.

36. Xylophilus tantillus. (Tab. VIII. fig. 28, ¢.)

Short and rather broad, opaque, densely clothed with fine, silky, appressed, ashy pubescence ; the head black ; the

prothorax and scutellum ferruginous; the elytra brownish-testaceous, with a rather broad angulated

black fascia below the middle, the fascia not quite reaching the suture, and connected laterally with a

marginal brownish stripe (not visible from above) which extends from the fascia upwards to the base.

Head very large and broad, densely and finely punctured; eyes (¢) very finely pubescent, very large,

occupying the whole of the side of the head (the head not at all extended behind them), rather narrowly

separated, coarsely granulated, somewhat feebly emarginate; antenne (g) long and pubescent, piceous-

brown, the two basal joints lighter, joints 1-3 slender and shining, 4—11 stout, equal in width, and opaque,

2 and 3 very short and equal in length, 4 more than twice as long as, and very much stouter than, 3, 4-10

subequal, 11 considerably longer than 10, ovate, acuminate; prothorax transverse, much narrower than

the head, the sides rounded and converging in front, straight behind, the surface very densely and some-

what roughly punctured ; elytra rather broad, much wider than the prothorax, widest at the middle, the

sides straight in front, the surface very closely and finely punctured ; beneath, the prothorax excepted,

piceous ; the legs (including the femora) very slender, rather short, testaceous, the apical half of the tibise

infuscate.

Length 14 millim. (¢.)

Hab. Guatemata, San Gerdnimo (Champion).

One male example. This minute species belongs to the section Aderus, Westw., it

having the second and third joints of the antenne very short and equal in length.

Aderus contains one European species, A. boleti (Marsh.)=populneus, Panz., this being

a very much larger insect than X. tantillus; and the Japanese X. gibbulus, Mars., also

belongs to it *.

Fam. ANTHICIDA.

Leconte and Horn [Class. Col. N. Am. p. 409 (1883)] include the “ Pédilides ” (less

Scraptia and its allies) and the “ Anthicides” of Lacordaire in one family, Anthicide:

this arrangement is here adopted, with the exception that their “ Xylophilini” are

excluded. This is a family more numerously represented in temperate than in tropical

regions; we have, however, to enumerate a large number of species from Central

America, whence two only have hitherto been recorded. We have as yet received

very little material from the sea-coast, or from the interior of Northern Mexico.

* Since ay remarks on the genus were written (anted, p. 166), I have found a single specimen of a

Xylophilus in Herr Hége’s Mexican collection ; it is a male of an undescribed species allied to X. bicolor.

EURYGENIUS. 191

Group PEDILIDES.

So far as at present known, this group is represented in Central America by three

genera—Lurygenius, Bactrocerus, and Macratria. Pedilus (= Corphyra, Lec.) is almost

certain to be found eventually in Northern Mexico.

Six species of Hurygenius have been described, five from North America and. one

from Brazil, the genus ranging as far north as Vancouver. A large number of closely

allied forms inhabit Australia.

* Pubescence long and coarse, on the elytra forming spots; punctuation coarse ;

anterior constriction of the thorax not well defined on the disc.

1. Hurygenius mexicanus. (Tab. IX. figg. 1,2; 2, fifth ventral segment, ¢ .)

Black or brownish-black, the elytra (the scutellar region excepted) and the front of the prothorax piceous-

brown or dark castaneous, somewhat thickly clothed with long, greyish, coarse, decumbent pubescence, and

with a few scattered semierect bristly hairs, the pubescence forming a median line on the prothorax and

numerous spots on the elytra. Head densely, roughly, and irregularly punctured, obsoletely canaliculate

behind ; eyes large and prominent, rather coarsely granulated, scarcely at all emarginate in front; antennz

piceous or piceous-brown, slender, joint 3 much longer than 2, joints 3 and 4 subequal, 5-10 decreasing in

length ‘but gradually increasing in width, 8-10 obconic, 11 a little longer than 10; prothorax moderately

convex, about as long as broad, the sides broadly rounded at the middle, gradually converging behind, and

constricted (but not abruptly) before the apex, the disc transversely depressed in front and canaliculate

thence to the base, the base rather deeply grooved within on either side laterally, the sculpture consisting

of closely packed, more or less confluent, very short, sinuous or curved raised lines, which are longitudinally

or obliquely arranged (the surface appearing vermiculate), the apical portion with umbilicated punctures ;

elytra impressed with exceedingly coarse, deep, oblong, closely placed punctures (which are here and there

confluent) to about the middle, the punctuation thence to the apex abruptly becoming very much finer,

shallower, and closer, the interstices more or less granular on the apical half; beneath very densely punc-

tured and pubescent, the ventral segments 3-5 smooth in the middle behind in the male; legs coarsely

and roughly punctured, thickly clothed with bristly whitish hairs, piceous, the base of the femora, the tibice

in great part, and the basal joint of the tarsi more or less reddish.

¢. Fifth ventral segment extended on either side posteriorly into a long and broad spoon-shaped lobe, the

inner margin of which is densely fringed with hairs (fig. 2); the same segment in the female largely

depressed in the middle behind.

Length 6-104 millim. (¢ 9.)

Hab. Mexico, Durango city, Chilpancingo and Iguala in Guerrero (Hége), Mescala

in Guerrero, Puente de Ixtla in Morelos (H. H. Smith), Cordova (Sal/é).

Eight examples. The peculiar sculpture of the elytra and other particulars separate

E. mexicanus from all the N.-American species and from the Brazilian E. reichei,

La Ferté. The pubescence is long and coarse, and decumbent, the upper surface

also with scattered semierect bristly hairs. In the almost unemarginate eyes, form of

pubescence, &c. it agrees very nearly with Leconte’s description of £. murinus, an

insect inhabiting Georgia and Alabama.

2. Eurygenius lanuginosus. (Tab. IX. fig. 3, ¢.)

Brownish-black, the front of the head and the elytra obscure castaneous, thickly clothed with long, coarse,

decumbent whitish pubescence, amongst which arise very many long, semierect, similarly-coloured

bristly hairs, the decumbent pubescence on the elytra here and there forming rather large spots, the

head and prothorax opaque, the elytra shining. Head very densely and moderately coarsely punctured,

canaliculate behind; eyes large, prominent, coarsely granulated, unemarginate in front ; antenne testa-

ceous, moderately slender, joint 3 much longer than 2, joints 8-10 comparatively elongate, not much

widened towards their apex (11 missing); prothorax not very convex, about as long as broad, the sides

broadly rounded before the middle, almost straight behind, and rather abruptly constricted before

the apex, the disc transversely depressed in front and canaliculate thence to the base, the base grooved

within on either side laterally, the surface very densely but not coarsely punctured (the sculpture much

hidden by the pubescence); elytra impressed with deep, coarse, closely placed, oblong punctures (which

are here and there confluent), the punctures gradually becoming finer and more shallow towards the apex,

those on the apical portion of the disc finer and more scattered than those at the sides; beneath densely

and finely punctured and thickly pubescent; legs coarsely and roughly punctured, thickly clothed with

very long bristly whitish hairs, piceous, the base of the femora and the tibie in great part reddish-

brown; fifth ventral segment broadly semicircularly emarginate, the sides not produced, in the male.

Length 83 millim. (<¢.)

Hab. Mrxico, Cordova (Sallé).

One male example. The differently sculptured thorax and elytra (the punctures on

the latter becoming gradually, not abruptly, finer beyond the middle, and also less close

on this part), the testaceous antenne, the more numerous and much longer semierect

hairs (in addition to the still coarser decumbent pubescence) of the upper surface, and

the shape of the fifth ventral segment in the male distinguish this insect at once from

E. mexicanus. The Californian £. constrictus, Lec., is a closely allied species; but, to

judge from the brief description, L. lanuginosus is quite distinct from it.

3. Kurygenius crinitus.

Brownish-black, the elytra brown with a slight coppery lustre, the entire upper surface clothed with rather

long, ashy, decumbent pubescence, amongst which arise longer semierect hairs, the decumbent pubescence

on the elytra here and there forming spots, the head and prothorax opaque, the elytra shining. Head

very densely but not very coarsely punctured, distinctly canaliculate ; eyes large and prominent, not

very coarsely granulated, almost unemarginate in front; antenne piceo-testaceous, moderately slender,

joint 3 considerably longer than 2, 8-10 very little widened towards their apex, 11 one and a half

times the length of 10; prothorax not longer than broad, somewhat flattened on the disc, the sides

broadly rounded, converging behind, and feebly constricted immediately before the apex, the disc with a

fine smooth central line from the base nearly to the apex, and shallowly transversely depressed in front,

the surface densely and confluently punctured ; elytra very closely and coarsely punctured, the punctures

gradually becoming finer towards the apex; beneath piceous-brown, shining, coarsely pubescent, thickly

and coarsely punctured, the venter and the middle of the metasternum much more sparsely so; legs coarsely

and roughly punctured, clothed with long bristly whitish hairs, piceous, the base of the femora and the

tibize in great part reddish. .

Length 64 millim. ( 9.)

Hab. Guatemata, Yzabal (Sallé).

EURYGENIUS. 193

One specimen. This species has the elytra more uniformly punctured than in

EL. mexicanus or E. lanuginosus. It nearly agrees with E. mexicanus in the form of

pubescence; but differs from it in the more filiform antenne, and in the less marked

anterior constriction and finer sculpture of the thorax. Apparently allied to the

N.-American £. murinus.

4. Hurygenius horridus.

Very elongate, blackish-brown or piceo-castaneous, the sides, suture, and base of the elytra castaneous in one

example, the upper surface thickly clothed with long, coarse, greyish decumbent pubescence and very

long erect bristly hairs, the pubescence on the elytra here and there forming spots. Head densely and

rugosely punctured ; eyes very large, almost entire; antenne ferruginous; prothorax longer than broad,

the sides rounded before the middle, slightly converging and almost straight behind, and constricted just

before the apex, the surface sculptured much as in EL. meaicanus, but less coarsely vermiculate, the disc

with a very distinct smooth central line; elytra rather shining, very elongate, impressed with coarse, deep,

closely placed punctures, which become finer towards the apex ; legs fusco-ferruginous, coarsely and roughly

punctured, and thickly clothed with very long bristly hairs; fifth ventral segment triangularly depressed

in the middle behind and the apex truncate in the male.

Length 9 millim. (<¢.)

Hab. Mexico, Villa Lerdo in Durango (Hége).

Two male examples. In this insect the pubescence is longer and coarser and the

erect hairs are more numerous than in either of the other species described here.

More elongate than . lanuginosus, the punctuation of the elytra less coarse at the

sides and base.

** Pubescence short, fine, and silky, uniform ; punctuation fine; anterior

constriction of the thorax very sharply defined on the disc.

5. Hurygenius uniformis. (Tab. IX. fig. 4,3.)

Narrowly elongate, subopaque; reddish-testaceous, the prothorax suffused with piceous-brown, the elytra

piceous-brown, with the suture and lateral margins, and an ill-defined stripe extending from the shoulders

downwards, testaceous ; the entire surface sparsely clothed with short, fine, silky, appressed pubescence.

Head densely and finely punctured (the punctures umbilicate in form), obsoletely canaliculate behind, the

neck very narrow; eyes comparatively small, not prominent, coarsely granulated, moderately emarginate

in front, black, distant from the base of the head; antenns very long, fully reaching to the middle

of the elytra, filiform, testaceous, joints 6-11 slightly infuscate, 11 a little longer than 10; prothorax

longer than broad, convex, broadest before the middle, the sides much rounded anteriorly, constricted

at the middle and thence to the base almost straight, and very abruptly constricted just before the

apex, the apical constriction connected with a deep groove which extends across the disc and forms a

short and very distinct neck, the dise obsoletely canaliculate (distinctly so before the apical constriction),

the basilar groove extending completely across, the surface very densely and finely punctured; elytra

densely and finely punctured, the punctures becoming coarser towards the base and finer and shallower

towards the apex; beneath densely punctured and pubescent, testaceous, the venter in great part piceous ;

legs and palpi reddish-testaceous, the former finely and densely punctured and clothed with short

silky pubescence.

longer and more erect intermixed hairs), smaller eyes, longer antenne, narrower neck,

small size, &c. distinguish this species at a glance from the others of the genus here

described. The apical joint of the maxillary palpi is also longer, and approaches that

of Stereopalpus; but the shape is more triangular than cultriform (as exhibited in

S. mellyi, La Ferté, the type of the genus Stereopalpus), and the insect in this respect

agrees better with Hurygenius. In the finely punctured elytra &c. EH. wniformis

approaches the Californian Stereopalpus pruinosus, Lec. ; from which, to judge from

the description, it differs in the sharply defined anterior constriction of the thorax,

longer antenne, small size, &c., as well as in the more dilated apical joint of the

maxillary palpi. The legs are less coarsely punctured and more slender than in

the preceding species.

BACTROCERUS.

Bactrocerus, Leconte, New Species Col. p. 143 (1866); Leconte & Horn, Class. Col, N. Am. p. 410

(1883).

The single known species of Bactrocerus is from Cape San Lucas, Lower California ;

the one from the Pacific slope of Guatemala now added agrees well with Leconte’s

definition of the genus, which may be readily distinguished from Stereopalpus and

Eurygenius by the long apical joint of the antenne (more especially in the male sex)

and the short broad apical joint of the maxillary palpi. The description of Leconte

was, no doubt, based upon male examples only.

1. Bactrocerus fasciculatus. (Tab. IX. fige. 5,3; 6,2.)

Piceous- or reddish-brown, the prothorax usually a little darker, thickly clothed with coarse brownish or white

appressed pubescence, the pubescence on the elytra here and there forming spots. Head densely and

roughly punctured, finely canaliculate in the middle behind; eyes large, prominent, rather coarsely

granulated, moderately emarginate in front; antenne slender, widening a little outwardly, joints 1-5

piceous, the base and apex of each more or less testaceous, 6-10 black, 11 testaceous or flavo-testaceous,

the latter slightly constricted at the middle in both sexes—in the male about three times, in the female

twice, the length of the tenth ; prothorax much longer than broad, not very convex, a little flattened on

the disc, the sides rounded just before the middle (the prothorax as wide here as at the base), moderately con-

stricted behind, and rather feebly (not abruptly) constricted before the apex, the disc transversely depressed

in front and shallowly canaliculate (the pubescence appearing to be obliquely combed off on either side of

a median line), the basilar groove distinct only at the sides, the surface densely and coarsely punctured

(the punctuation hidden by the pubescence); elytra very much wider than the prothorax, very coarsely

and deeply punctured, the punctuation becoming still coarser and deeper towards the base, finer and closer

towards the apex, and here and there confluent, the minute interspaces almost granular at the apex;

beneath densely punctured and thickly pubescent; legs coarsely and roughly punctured and thickly

clothed with bristly hairs, piceous, the base and apex of the femora, the basal half of the tibia, and the

base of the first joint of all the tarsi more or less reddish-brown; fifth ventral segment in the male

transversely depressed in the middle behind, unemarginate.

apical joint of the antenne (in B. concolor equal to the preceding four joints united),

more distinctly emarginate eyes, the rather feeble and not abrupt anterior constriction

of the thorax, and fasciculate elytral pubescence. The apical joint of the maxillary

palpi is broad and subtriangular, the apical side rather longer than the inner side.

The colour of the pubescence is variable. The specimens obtained exhibit a very

great disparity in size, the males (as in some Cidemeride) being very much smaller

than the females.

MACRATRIA.

Twenty-nine * species of this very widely distributed genus have been described,

chiefly from the warmer parts of the globe; eleven are here recorded from Central

America. These latter are so closely allied that they are exceedingly difficult to

discriminate; this cannot always be satisfactorily done till the sex of the individual

under examination is ascertained. In some species the apical joint of the antenne is

much longer in the male than in the female, while in others it is of equal length in

both sexes. The form of the terminal segments (dorsal and ventral) of the hind body

often affords a good distinguishing character, more especially in the female sex. In

the male the fifth segment (dorsal and ventral) is usually more or less broadly truncate

(also emarginate in some species) at the apex; in the female it is longer, with the apex

of the dorsal portion rounded or produced in the middle and at the sides. In the

female of UM. incana the apex of the fifth dorsal segment} has not only a long

horizontal projecting piece in the middle (resembling the cedeagus of the male), but

the sides are also angularly produced. In the female of WM. princeps the fifth dorsal

segment is divided down the centre, and beyond this a long projecting piece from the

middle of the sixth segment (similar to that of the fifth in MW. incana &c.) is visible.

Our material is not sufficient to enable me to examine these parts in all the different

species; I. princeps exhibits, however, a very different structure from that of the

other members of the genus. The importance of the sexual characters in this genus

has been almost entirely overlooked by recent authors, and in the descriptions of many

of the eastern Macratrie no mention whatever is made of the sex of the, individuals

described; the males of some of these latter have the anterior tibie dilated. As in

Eurygenius and Bactrocerus, the eyes are clothed with short hairs. The following table

will assist in the identification of the Central- American, ‘forms: —

agree so nearly with La Ferté’s description and figures of M. goudotiw from Colombia

(which is based upon a single male example), that I, at first, identified them with it;

there is, however, in Mr. F. Bates’s collection a male example, from HEga, of a

Macratria which agrees still more closely with La Ferté’s figure; this last-mentioned

specimen has the apices of the elytra separately rounded (the form of the sutural

angle is, unfortunately, not mentioned in the description), while in M. princeps they

are rather sharp*. If this determination is correct, M. princeps differs from M. goudotii

not only in this respect, but in its more robust form, rather longer apical joint of the

antenne, stouter and more ferruginous legs, wider thorax, and still more coarsely

granulated eyes. The lanciform projection at the apex of the terminal segment of the

female, at first sight, resembles the central sheath of the cedeagus of the male, for which

it might easily be mistaken. The short, broad head, large, oblique, and very coarsely

granulated eyes, stout legs (the tarsi included), comparatively broad form, large size, &c.

separate IM. princeps from all the following species. The irregular rows of punctures

on the elytra are scarcely distinguishable through the pubescence, and the punctures

are separated one from another by somewhat granular elevations which become coarser

towards the base. The thorax has the flanks somewhat hollowed out, the lateral limits

being more sharply marked than in any of our other species, except I. canescens. ‘The

Mexican example is much larger than those from Guatemala.

2. Macratria canescens.

Black, the head reddish in front, the labrum paler, subopaque, very densely clothed with yellowish-grey silky

pubescence, and with scattered erect hairs. Head moderately large, very densely and somewhat roughly

punctured, slightly shining, the space behind the eyes broad and rounded laterally, the occipital channel

short but distinct; eyes comparatively small, moderately prominent, not very coarsely granulated ; palpi

that La Ferté could have overlooked a similar character in M. goudoti.

testaceous; antennz (2 ) testaceous, rather stout, joints 9 and 10 triangular, each very much wider than,

and nearly twice as long as, 8, 11 about one third longer than 10 and pointed; prothorax distinctly wider

than the head, one and a half times as long as broad, the sides much rounded anteriorly and strongly

converging behind, the flanks concave (the lateral limits of the prothorax somewhat sharply defined), the

basilar groove very deep and extending completely across, the surface very roughly and confluently punc-

tured; elytra moderately long, comparatively broad, subparallel in their basal half, and thence narrowing

to the apex, with irregular rows of fine but deep punctures extending from the base to far beyond the

middle, and a fine longitudinal impressed line extending from the shoulders downwards, the interstices

very densely and minutely punctured, and also with a few widely scattered punctures similar to those of

the striz, these punctures, however, more numerous along the suture and at the base, the apices rather

sharp; legs stout (the femora much thickened towards the apex), the front and middle pairs testaceous

with the base of the tibize and the femora in the middle above piceous, the hind pair piceous with the base

and extreme apex of the femora reddish and the tips of the tarsi testaceous,

Q. Fifth dorsal segment furnished in the middle at the apex with a long slender projecting piece which is

curved downwards, the apical margin somewhat angularly extended on either side laterally.

Length 53 millim. ( 9.)

Hab. Mexico, Jalapa (fHoge).

One male example. The longer, narrower, and more rounded head, the smaller and

more finely granulated eyes, the deep basilar groove of the thorax, the very distinct

rows of punctures on the elytra, the less elongate shape, &c. distinguish WZ. canescens

from MV. princeps and M. goudotii; and the larger head, shorter and broader thorax

(the sides of which are much more rounded anteriorly, the flanks more hollowed, the

basilar groove deeper, and the sculpture coarser), &c. separate it from I. incana and

M. tropicalis. The elytra are shaped and sculptured as in these latter, from both of

which it differs in the form of the fifth dorsal segment in the female: this segment is

furnished with a long projecting piece in the middle as in MW. encana, the apical margin,

however, being less sharply produced on either side laterally.

3. Macratria incana. (Tab. IX. figg. 8,3; 84, fifth ventral segment, 3; 8 4,

sixth ventral segment, ¢; 8c, edeagus, ¢; 9, fifth ventral segment, 2; 94a, fifth dorsal

segment, @ .)

Black or pitchy-black, the head reddish or testaceous in front, the labrum paler, the disc of each elytron from

just below the base to the apex usually indeterminately brownish (the suture broadly, the sides, and the

extreme base remaining of the ground-colour), subopaque, very densely clothed with fine, silky, ashy or

yellowish-grey pubescence, and with scattered erect hairs. Head very densely and finely punctured,

‘rounded at the sides behind the eyes, the occipital channel shallow and not extending upwards; eyes

moderately large, not prominent; antenne rather slender, testaceous, with joints 7-10 and the basal

half of 11 piceous or brownish (in some examples entirely testaceous), 3 only a little longer than 2, 9

and 10 triangular, each much longer and wider than 8, 11 in both sexes about half as long again as 10

and pointed; prothorax nearly twice as long as broad, not or very little wider than the head, the sides

moderately rounded anteriorly and converging behind, the groove on either side of the base deep (in fresh

specimens partly hidden by the pubescence), the surface very densely and roughly punctured; elytra

subparallel in their basal half, and thence somewhat rapidly narrowing to the apex, with irregular rows

of fine, rather deep, punctures extending from the base to far beyond the middle, and a fine longitudinal

impressed line extending from the shoulders downwards, the interstices very densely and exceedingly

minutely punctured, and also with a few very widely scattered punctures similar to those of the strie,

these punctures, however, more numerous along the suture and at the base, the apices rounded ; beneath

coloured as above, very densely punctured and pubescent; legs stout (the femora much thickened towards

the apex), the front and middle pairs flavo-testaceous or testaceous with the base of the tibie piceous and

sometimes the apices of the femora brownish, the hind pair piceous or piceous-brown with the knees and

the tips of the tarsi testaceous (in one example the four anterior femora are in great part piceous, in others

the hind tibiz are testaceous, except at the apex).

3. Fifth ventral segment broadly truncate at the apex, the apical margin feebly bisinuate (fig. 8a); the

corresponding dorsal segment very shallowly and broadly emarginate at the apex.

9. Fifth ventral segment deeply triangularly emarginate (fig. 9); the corresponding dorsal segment furnished

with a projecting piece in the middle, and angularly extended on either side (the apical margin thus

appearing tridentate) (fig. 9 a).

Length 4-53 millim. (¢ 9.)

Hab. Mxxico, Atoyac, Teapa (H. H. Smith); Guatemaua, Teleman and San Gerdénimo

in Vera Paz (Champion).

Apparently not uncommon in South-eastern Mexico and Eastern Guatemala. This

species is densely pubescent, and varies considerably in size, and also in the colour of

the legs and antennz. ‘The less parallel shape, shorter apical joint of the antenne,

and still more finely punctured elytral interstices distinguish it easily from the

N.-American VM. murina. From the Colombian WV. sericea, La Ferté (to judge from

the description), it differs in the less parallel shape, the shorter third joint of the

antenne (it being only a little longer than the second), duller elytral interstices, &c.

In the male the sixth ventral segment is furnished on either side with two long,

straight, slender processes which are clothed with long hairs at the tip (fig. 85), the

corresponding dorsal segment being divided down the middle into two pieces which

are pointed and somewhat hooked at the end (the tips often visible beyond the end of

the body in dried specimens *); and the central sheath of the cedeagus has an accom-

panying long, flattened piece on either side (forming part of the tubular piece enclosing

the central sheath), the ends of which are abruptly truncate, bent inwards, and some-

what hooked within (fig. 8 ¢).

4. Macratria tropicalis.

Pitchy-black or obscure reddish-brown, the head paler in front, the disc of the elytra brownish; the occipital

channel short and deep, not extending upwards; antenne testaceous, formed as in MM. incana; palpi

testaceous; prothorax, elytra, and legs as in M. incana, the legs equally variable in colour; fifth dorsal

segment arcuate-emarginate at the apex in the male, rounded and entire in the female.

Length 43-53 millim. (¢ 9.)

Hab. Guatemata, Panzos (Conradt), Teleman (Champion).

One male from Teleman and two female examples from Panzos. Except for the

different form of the fifth dorsal segment in the female, this insect is so closely allied

to UM. incana as to be scarcely separable from it; the occipital channel of the head is,

however, deeper in both sexes. The single male, which is somewhat doubtfully

referred to the same species, is much smaller in size, and has the antenne more

slender, and the basilar groove of the thorax deeper. The apical joint of the antennz

is about half as long again as the tenth in both sexes.

5. Macratria parallela. (Tab. IX. fig. 10, 3.)

Black, the head reddish in front, slightly shining, thickly clothed with rather coarse brownish pubescence and

with scattered erect hairs. Head densely but not very finely punctured, somewhat rounded at the sides

behind the eyes, the occipital channel short but distinct; eyes moderately large, not prominent; antenne

(d) comparatively long, extending a little beyond the base of the prothorax, black, joints 1-4 and 11 at

the extreme tip more or less testaceous, joints 2-8 slender, 3 distinctly longer and more slender than 2, 9

and 10 triangular and longer and wider than 8, 11 three and a half times as long as 10; prothorax about

twice as long as broad, not wider than the head, the sides moderately rounded anteriorly and converging

behind, the basilar groove deep and extending completely across, the surface very densely and roughly

punctured ; elytra subparallel (the sides, however, slightly converging from the base), with irregular rows

of fine but deep punctures extending from the base to far beyond the middle and a fine longitudinal

impressed line extending from the shoulders downwards, the interstices densely and somewhat roughly

punctured, the base and sutural region impressed with coarser punctures (as coarse as those of the strie),

the apices rounded; beneath coloured as above, very densely punctured and pubescent ; legs comparatively

slender, rather long, the femora moderately clavate, piceous, the knees, the base of the femora, and the

tarsi (except the basal joints of the hind pair) more or less reddish or testaceous ; fifth dorsal segment

truncate and emarginate in the male.

Length 5-54 millim. (<¢.)

Hab. Panama, Volcan de Chiriqui 4000 feet (Champion).

Three examples, all males. The duller and more densely and less finely punctured

head distinguishes this species from the following, to which it is very closely allied ;

the much longer apical joint of the antenne (in the male) and the denser punctuation

of the head separate it from MV. rujfifrons. |

6. Macratria nitidiceps.

Closely allied to and of the general form of M. parallela. The head indeterminately reddish or testaceous in

front, less densely and more finely punctured, almost smooth behind, shining; the antenne black, the

three or four basal joints and the extreme tip of the apical one usually testaceous, sometimes with only

the two basal joints lighter, joint 3 very little longer than 2, 9 and 10 triangular, longer and wider than

8, 11 in the male fully three times, in the female twice, as long as 10; the prothorax and elytra as in

M. parallela; the legs in some specimens almost entirely piceous, in others testaceous or flavo-testaceous

with the knees, tibia, and tarsi piceous-brown or brownish; the fifth ventral and fifth dorsal segments

truncate at the apex in the male, rounded in the female.

Length 43-53 millim. (¢ 9.)

Hab. Muxtco, Coscomatepec, Juquila, Cordova (Sallé), Cerro de Plumas, Jalapa

(Hoge).

Numerous examples. In this insect the head is more sparsely and more finely

punctured than in any other of the Central-American representatives of the genus.

7. Macratria rufifrons.

Closely allied to M. parallela, and differing as follows:—The head shining, less densely but somewhat coarsely

punctured, the anterior half reddish; the antenne black, with the four basal joints and the tip of the

eleventh testaceous, joints 9 and 10 triangular, longer and wider than 8, 11 in the male two and a half

times, in the female not quite twice, the length of 10; prothorax, elytra, and legs as in M. parallela;

fifth dorsal segment ( ¢) very broadly truncate at the apex.

Length 5-6 millim. (¢ 2.)

Hab. Guatema.a, San Gerénimo, Sinanja (Champion).

Two examples. Very closely allied to YM. parallela and M. nitidiceps. The punc-

tuation of the head is coarser and closer than in the latter, but not so dense as in the

former ; the apical joint of the antenne in the male is shorter than in either of these

species, it being only a little longer than in the female of M/. nitidiceps.

8. Macratria guatemalena.

Black, the head reddish in front, the labrum testaceous, slightly shining, thickly clothed with brownish pube-

scence and with scattered erect hairs. Head densely and finely punctured, somewhat rounded at the

sides behind the eyes, the occipital channel deep; eyes moderately large, not very prominent ; palpi

testaceous, the last joint of the maxillary pair sometimes darker; antenne testaceous, with the three

outer joints darker (in one example the tip of the eleventh only slightly infuscate), slender, joint 2 not

much shorter than 8, joints 9 and 10 triangular and each much longer and wider than 8, 11 in both

sexes nearly equal to 9 and 10 united; prothorax about one and a half times as long as broad, not wider

than the head, the sides moderately rounded anteriorly and constricted behind, the groove on either side

of the base deep, the surface very densely and roughly punctured ; elytra parallel, with somewhat regular

rows of fine but deep punctures extending from the base to far beyond the middle and a fine longitudinal

impressed line extending from the shoulders downwards, the interstices densely and somewhat roughly

punctured, the base and scutellar region impressed with coarser punctures (similar to those of the strie),

the apices rounded ; legs rather long and slender, the femora moderately clavate, testaceous, with the

knees and the base of the femora of the two anterior pairs and the hind pair in great part piceous; fifth

dorsal segment ( ¢ ) truncate at the apex.

Length 43-5 millim. (¢ 2.)

Hab. Guatema.a, Cubilguitz, Capetillo (Champion).

Three examples. This insect closely resembles UZ. parallela, M. nitidiceps, and

M. rujfifrons, but differs from all these in the much shorter apical joint of the antenne

in the male; this joint is similarly formed in both sexes, and not quite twice the length

of the preceding one. The female so closely resembles that sex of MZ. rujifrons that it

can only be distinguished by the rather more densely punctured head and the darker

anterior and middle legs. The description is taken from a pair from Cubilguitz; the

single female from Capetillo has the five outer joints of the antenne dark, and also

differs in some other particulars.

The North-American M/. confusa, Lec., is apparently an allied species.

9. Macratria crassicornis.

Black, the head dark reddish-brown, the labrum testaceous, rather shining, thickly clothed with fine, silky,

brown pubescence and with scattered semierect hairs. Head thickly and rather coarsely punctured, some-

what rounded at the sides behind the eyes, the occipital channel short. but deep; eyes moderately large,

not very prominent ; last joint of the maxillary palpi piceous, the other joints testaceous; antenne (¢ )

entirely black, stout, gradually widening outwardly, joints 9 and 10 triangular and each considerably

longer and wider than 8, 11 twice as long as 10 and pointed; prothorax one and a half times as long as

broad, not wider than the head, the sides moderately rounded anteriorly and converging behind, the basilar

groove deep and extending completely across, the surface densely and roughly punctured; elytra long and

parallel, with irregular rows of fine shallow punctures extending from the base to far beyond the middle

and a fine longitudinal impressed line extending from the shoulders downwards, the interstices finely,

densely, and somewhat roughly punctured, the apices rounded; beneath black, densely punctured and

pubescent; legs rather long and slender, the femora moderately clavate, black, the apical joints of the

tarsi testaceous ; fifth ventral segment truncate and broadly and shallowly emarginate in the male.

Length 52 millim. (¢.)

Hab. Mexico, Jalapa (Hoge).

One male example. Closely allied to WM. nigricornis, and differing thus :—The head

larger, rounded at the sides behind the eyes (not obliquely narrowing), and much less

‘closely punctured; the antenne stouter, the apical joint of the same length in the

male; the elytra with more irregular series of punctures and the interstices more

roughly and less densely punctured; the legs black. The stout and entirely black

antenne (the apical joint of which is much shorter in the male), the more thickly and

less finely punctured head, and the more finely punctured elytra (the punctures of the

series being much shallower), separate it from MM. nitidiceps &c.

10. Macratria obsoleta. (Tab. IX. fig. 11, ¢.)

Black, the head reddish-testaceous in front, the labrum pale flavous, thickly clothed with brownish pubescence,

the head and prothorax also with long erect hairs, shining (when denuded of pubescence). Head com-

paratively long, somewhat angularly dilated on either side behind the eyes, the post-ocular portion broad,

finely and thickly punctured, the occipital channel quite shallow ; eyes moderately large, not very promi-

nent, converging in front; palpi testaceous; antenne (g) comparatively long and slender, black, joints

1-4 more or less testaceous, 9 and 10 triangular, each wider and much longer than 8, 11 rather more

than twice the length of 10 and acuminate; prothorax about one third longer than broad, a little wider

than the head, the sides moderately rounded anteriorly and converging behind, the groove on either side

of the base deep but not extending inwards, the surface densely punctured ; elytra subparallel, thickly,

roughly, and confusedly punctured, with a fine sharp groove extending from the shoulders nearly to the

apex, the disc without trace of rows of coarser punctures or irregular rows of granular elevations, the

interspaces smooth and shining, the apices rounded ; legs slender, comparatively long (the tarsi especially),

the femora clavate beyond the middle, testaceous, the outer half of the hind femora, all the tibie at the

base, and the basal joint of all the tarsi piceous, the intermediate femora also darker towards the apex ;

the basal joint of the hind tarsi much longer than the following joints united ; fifth dorsal and fifth ventral

segments ( ¢ ) truncate at the apex.

Length 5 millim. (¢.)

Hab. Costa Rica, Volcan de Irazu 6000 feet (Rogers).

One maleexample. This species differs from all others of the genus here enumerated

in the elytra being confusedly punctured, without trace of irregular rows of punctures

or of granular elevations on the disc. The groove on either side of the base of the

thorax is not extended inwards so as to meet the opposite one at the middle (as in

the allied species), these being widely separated in W/. obsoleta. The head is somewhat

angularly dilated at the sides behind the eyes, not rounded.

MACRATRIA.—NOTOXUS. , 203

11. Macratria nigricornis. (Tab. IX. fig. 12.)

Black, the anterior part of the head (and the labrum) broadly and abruptly flavo-testaceous, subopaque, thickly

clothed with fine, silky, brownish pubescence and with scattered erect hairs. Head rather long and

narrow, very densely and very finely punctured, obliquely narrowed behind the eyes, the occipital channel

short but deep; eyes moderately large, rather prominent; last joint of the maxillary palpi piceous or

black, and sometimes the other joints also; antennex black (the basal joint testaceous beneath in one

example), comparatively stout, gradually widening outwardly, joints 9 and 10 triangular and each con-

siderably longer and wider than 8, 11 twice as long as 10 and pointed ; prothorax at least one and a

half times as long as broad, very little wider than the head, the sides moderately rounded anteriorly and

converging behind, the basilar groove deep, the surface densely, roughly, and confluently punctured ;

elytra parallel, with somewhat regular rows of fine shallow punctures extending from the base to far

beyond the middle and a fine longitudinal impressed line extending from the shoulders downwards, the»

interstices very densely and exceedingly minutely punctured, the sutural one with scattered punctures

like those of the stria, the apices rounded; legs slender, but with the femora strongly clavate, black, the

femora broadly testaceous in the middle (the base and apex only black); fifth dorsal and fifth ventral

segments slightly truncate, and the latter emarginate, in the male.

Length 43-54 millim. (<¢.)

Hab. Mexico, Coscomatepec (Sallé); GuatemaLa, Chacoj (Champion); Nicaraava,

Chontales (Belt).

Four examples, two of which are certainly of the male sex. This species differs from

the allied forms in the head being obliquely narrowed behind the eyes. The antenne

are black, comparatively stout (the intermediate joints becoming gradually wider, so that

the transition from the eighth to the ninth is not very abrupt), and the eleventh joint

in both sexes is as long as 9 and 10 united. The interstices of the elytra are more

minutely and much more densely punctured than in UM. nitidiceps, from which it also

differs in the denser punctuation and colour of the head. ‘The coloration of the legs is

apparently constant.

Group ANTHICIDES.

The genera Notorus and Anthicus are both well represented in Central America, and

when the Central-American coast-region is more thoroughly investigated additional

species of each genus are certain to be discovered. Tanarthrus, Lec., should occur in

Northern Mexico ; the three known species are from the Colorado Desert and Utah:

they are said to fly and run on salt mud, after the manner of a Cicindela.

known from America north of Mexico, two from the northern part of South America,

and one from the Antilles*. Sixteen are now recorded from Central America, eight of

which appear to be peculiar to Mexico. We follow, as nearly as possible, the arrange-

ment adopted by Dr. Horn in his excellent monograph of the North-American species

(op. cit.). As this author remarks, the elytral markings are often variable and not

always to be relied upon as specific characters unless supported by other marks of

distinction. Important characters exist in some species in the form of the apices of

the elytra (not only in the male but in the female also) and also in that of the fifth

ventral segment (in the male). We have,unfortunately, very insufficient material of

several of the species (more particularly of the Mexican ones), in some cases one sex

only being represented ; so that we are unable to describe the sexual marks of distinc-

tion in WV. opacus, N. ventralis, N. fraternus, N. truncatipennis, N. crucifer, &c.

Various Nearctic and Palearctic species (NV. monoceros, Linn., N. anchora, Hentz,

&c.) have the sutural angles of the elytra in the male retracted and the apices obliquely

truncate and more or less spinous externally ; none of the Central-American species of

which the males are known possess this peculiarity. MV. acuminatus is remarkable from

having the apices of the elytra subacuminate in both sexes.

These insects are chiefly found in sandy places, not only upon the ground, but upon

low herbage and bushes.

The Central-American species may be grouped thus :—

Elytra with fine or moderately coarse decumbent pubescence, sometimes

with scattered, longer, serially arranged, decumbent or erect hairs ;

apices conjointly rounded in both sexes, or separately rounded in the

male, or truncate in the female.

hairs in front; the prothorax reddish-testaceous, the horn and crest piceous, sparsely clothed with fine,

silky, decumbent, ashy pubescence and with scattered erect hairs, the basilar groove on either side filled

with dense whitish pubescence ; elytra leaden-black, dull, clothed with exceedingly short, fine, decum-

bent, ashy pubescence and with scattered, rather longer, serially arranged, decumbent hairs. Head

minutely punctured, the front concave, the eyes moderate in size; antenne pitchy black, the apical joint

lighter; prothorax broader than long, minutely and rather sparsely punctured—the horn moderately long,

rather narrow, slightly wider in the female, oval at the tip, the sides coarsely serrate and margined, the

sutural angle obtuse; beneath piceous ; legs pitchy-brown.

Length 3 millim.

Hab. Panama, San Lorenzo in Chiriqui (Champion).

Two examples, apparently male and female. Closely allied to J. bicolor (Say), a

common insect in the Atlantic States of North America, from a type of which (kindly

communicated by Dr. Horn) it differs in its narrower shape, narrower thoracic horn,

much more finely punctured elytra, darker head, antenne, legs, and thoracic horn, and

smaller size. The elytra are very opaque, and clothed with exceedingly short, fine,

decumbent pubescence and serially arranged rather longer hairs. The head and thorax

bear scattered long erect hairs, the thoracic horn is clothed with long hairs beneath,

and the basilar groove is filled on either side with dense whitish pubescence.

2. Notoxus atripennis.

Elongate, rather narrow, opaque; the head piceous-brown, testaceous in front, finely and sparsely pubescent ;

the prothorax reddish-testaceous, the horn and crest piceous, sparsely clothed with long, silky, decum-

bent fulvous pubescence, the horn above and beneath with rather long hairs, the basilar groove on

either side filled with dense whitish pubescence; elytra dull black, clothed with exceedingly short,

fine, decumbent, ashy pubescence. Head finely punctured, the~front slightly concave, the eyes large ;

moderately long, rather broad, rounded at the tip, the sides serrate and margined, the crest not much

raised, its margins indicated by a row of coarse tubercles; elytra long, widest about the middle, very

finely, shallowly, and closely punctured, the usual oblique depression below the shoulders obsolete, the

humeri moderately distinct, the apices conjointly rounded, the sutural angle obtuse ; beneath piceo-testa-

— ceous ; legs pitchy-brown. ;

Length 33 millim. (@.)

Hab. GuateMaa, Chacoj in the Polochic valley (Champion).

One female example. The eyes in this species are ‘unusually large, considerably

larger than in V. ruficollis or N. bicolor. ‘The thorax is‘longer than in N. ruficollis ;

the pubescence on the disc is longer and fulvous in colour ; ‘and the horn is broader and

less coarsely serrate laterally. As in V. ruficollis, the elytra are much more finely and

shallowly punctured than they are in WV. bicolor.

Elongate, narrow, piceous or piceous-brown, shining, somewhat thickly clothed with fine decumbent pubescence,

without intermixed erect hairs; the prothorax varying in colour from piceous to piceo-testaceous, the

horn reddish or reddish-testaceous; the elytra testaceous, with a spot on either side of the scutellum

below the base, a rather broad transverse fascia at or just beyond the middle, and the apex, piceous, the

piceous colour in some examples extended along the suture from the median fascia to the postscutellar

spot and also along the lateral margin to the base. Head with a few erect hairs, finely and sparsely

punctured, the front more or less concave ; prothorax globose, as long as broad, minutely and very sparsely

oval, finely and moderately closely punctured, the punctuation shallower towards the apex, the usual

oblique depression below the shoulders deep in both sexes, the humeri distinct, the apices conjointly

rounded in both sexes, the sutural angle rather obtuse; beneath varying in colour from piceous to piceo-

_ testaceous; legs and antenne testaceous, the latter and the femora and tibie sometimes slightly infus-

cate; fifth ventral segment with a shallow triangular depression in the middle at the apex, and the apex

truncate in the male.

Length 23-3 millim. (¢ 9.)

Hab. Guatemaa, Aceytuno (Salvin), Guatemala city (Salvin, Champion), Capetillo,

Calderas (Champion).

Not rare on the central plateau of Guatemala, at elevations between 5000 and 7000

feet. Narrower and more shining than WN. acwminatus; the apices of the elytra con-

jointly rounded (not subacuminate) in both sexes; the elytral pubescence entirely

decumbent, without intermixed erect hairs. The colour is variable. ‘The antenne are

very long and comparatively slender in the male, shorter and stouter in the female.

The thorax is shining and globose.

4. Notoxus eximius. (Tab. IX. figg. 15, 15a, 2.)

Moderately elongate, narrow, piceous, thickly clothed ‘with very fine decumbent pubescence, without inter-

mixed erect hairs; the prothoracic horn rufous or testaceous; the elytra piceous, each with oblique

stripe below the shoulders (not reaching the suture) and a curved oblique stripe beyond the middle

(curving upwards and narrowing towards the suture—in some specimens reaching it, in others not

extending so far inwards) testaceous or fusco-testaceous, the pubescence on these stripes more or less

whitish—in some examples silvery-white, the base and apex sometimes paler; the pubescence on the

head and on the base of the prothorax whitish. Head sparsely and minutely punctured, with a few erect

hairs in front, the front concave in the middle; prothorax globose, as long as broad, very densely and

minutely punctured, opaque—the horn moderately Jong, narrow in the male, much broader in the female,

rounded at the tip, the sides serrate and distinctly margined, the crest slightly raised, its margins feeble

or merely indicated by a row of tubercles ; elytra narrowing from the middle to the base, oblong-oval,

minutely and densely punctured, slightly shining, the usual oblique depression below the shoulders deep in

both sexes, the humeri distinct, the apices conjointly rounded in both sexes, the sutural angle rather

obtuse; beneath piceous; antenne testaceous, the outer joints often darker ; legs testaceous, the outer

halves of the femora sometimes infuscate or piceous ; fifth ventral segment unimpressed and broadly and

shallowly emarginate at the apex in the male.

Length 24-22 millim. (¢ @.)

Hab. GuateMata, near the city, Duefias, Zapote (Champion); Nicaragua, Chinandega

(Sallé); Panama, Tolé (Champion).

NOTOXUS. 207

Found in abundance at Zapote, more sparingly elsewhere. This elegant little species

is the smallest of the Central-American Wotoxi. It may be readily identified by the

two oblique fasciz on each elytron (one occupying the oblique post-humeral depression,

the other extending upwards and nearly or quite reaching the suture); the punctuation

is dense, not only on the thorax but on the elytra also, the thorax being quite opaque ;

the pubescence is fine and decumbent; the oblique depression on the elytra is deep in

both sexes; the thoracic horn varies greatly in width in the two sexes (in one female

example it is twice as wide as in some males). The North-American WV. bifasciatus,

Lec., approaches N. eximius in some of its characters, and an undescribed Notoxus from

Santarem on the Upper Amazons (specimens of which are contained in the British-

Museum collection) also comes near it.

5. Notoxus opacus. (Tab. IX. figg. 16, 16a, ¢.)

Elongate, subparallel, opaque, piceous, thickly clothed with rather coarse decumbent pubescence and scattered,

serially arranged, moderately long, erect hairs ; the prothoracic horn rufous ; the elytra with a large spot on

either side of the suture immediately below the base, a rather broad fascia just beyond the middle (formed

by a curved transverse band on each elytron, these extending upwards at the suture), and an apical patch,

these markings black and clothed with dark brown pubescence, the rest of the surface ofa dull leaden colour

and clothed, like the head and prothorax, with ashy pubescence. Head rather narrow, very finely and

sparsely punctured, the front slightly concave; prothorax relatively small, about as long as broad, very

finely and sparsely punctured, slightly shining—the horn ( ¢ ) long and narrow, rounded at the tip, very

feebly margined and slightly serrate at the sides, the crest moderately raised, a little narrower than the horn,

and finely margined ; elytra moderately long, comparatively broad, subparallel, very opaque, closely and very

finely punctured, the usual oblique depression below the shoulders rather deep (the postscutellar spot appear-

ing raised), the humeri distinct, the apices conjointly rounded ; beneath and the antennz piceous, the basal

joints of the latter ferruginous; legs piceous, the tibie at the base and the tarsi, in part, ferruginous ;

fifth ventral segment deeply transversely concave in the middle behind and the apex truncate in the

male.

Length 33 millim. (<¢.)

Hab. Mexico, Cerro de Plumas (fége).

One. male example. A very distinct species, recognizable by the opaque elytra,

narrow head and thorax, and long and narrow thoracic horn; the transverse concavity

of the fifth ventral segment of the male is very deep. ‘The markings of the elytra are

clothed with dark brown pubescence, the rest of the surface with ashy pubescence, the

transition from one to the other being very abrupt, though the ground-colour of the

elytra itself is very dark. When denuded of pubescence, the thorax is moderately

shining and the elytra are opaque.

6. Notoxus ventralis. (Tab. IX. figg. 17, 17a, ¢.)

Elongate, subparallel, piceous, thickly clothed with fine decumbent pubescence, without intermixed erect hairs ;

the disc of the prothorax and the horn and crest reddish-testaceous ; the elytra with a large elongate-

subtriangular lateral patch before the middle extending to the shoulders and along the base, and a narrow

strongly angulated fascia (formed by a V-shaped mark on each elytron) considerably beyond the middle, tes-

taceous, these marks clothed with whitish pubescence, the rest of the surface with brownish pubescence (the

208 HETEROMERA.

triangular mark darker in colour in one example, but its shape well defined by whitish pubescence).

Head finely and rather thickly punctured, finely pubescent, with a few short erect hairs in front,

the front flat or slightly concave; prothorax broader than long, sparsely and finely punctured, slightly

shining—the horn(<) long and subparallel, rather narrow, oval at the tip, distinctly margined, the

sides not or very feebly serrate, the crest moderately raised, considerably narrower than the horn, and

sharply margined; elytra subparallel, moderately long, shining, closely and finely punctured, the usual

oblique depression below the shoulders shallow, the humeri distinct, the apices conjointly rounded ;

beneath piceous ; legs testaceous or fusco-testaceous, the femora piceous in one example ; antennz testa-

ceous or ferruginous, with the outer joints a little darker; fifth ventral segment with a deep triangular

excavation at the apex, and the apex a little emarginate, in the male.

Length 3-33 millim. (<.)

Hab. Mexico, Guanajuato (Sallé), Jalapa (Hoge).

Two male examples. In the deep triangular excavation of the fifth ventral segment

in the male and in the fine and entirely decumbent pubescence this species resembles

the North-American V. nuperus, Horn; the elytra, however, are differently marked and

shining (not opaque), and the triangular excavation of the fifth ventral segment does not

extend to the tip of the preceding segment *. The large triangular whitish-pubescent

antemedian lateral patch and the narrow W-skaped similarly pubescent postmedian fascia

of the elytra are characteristic of this species, these whitish-pubescent markings being

present in both examples, though in one the testaceous colour is partly obliterated.

In the British-Museum collection there is a mutilated specimen of a Notorus from

Mexico which is perhaps referable to this species (or it may prove to be the other sex

of NV. truncatipennis) ; it has the thoracic horn and crest similarly shaped, but the post-

basal depression ot the elytra is very deep and the apices of the latter are somewhat

oblique and the sutural angle a little produced. Additional specimens of this and of

the following two species are much required, not only to determine the sexual marks

of distinction, but to show the amount of variation to which each is subject.

7. Notoxus fraternus.

Elongate, subparallel, piceous, shining, somewhat thickly clothed with moderately coarse decumbent hairs and

with scattered, more erect, serially arranged, rather longer hairs intermixed; the prothorax with the

extreme base, and in one example the horn and the sides and apex also, rufous; the elytra in one example

with a transverse testaceous patch on the middle of the disc towards the apex, in the other with a small

reddish spot on the disc before the middle, for the rest entirely piceous, a large, lateral, triangular,

antemedian patch and a postmedian transverse fascia (the ground-colour of which is partly testaceous in one

example) clothed with whitish pubescence, the rest of the surface with brownish pubescence. Head sparsely

and minutely punctured, finely pubescent, with a few short erect hairs in front, the front slightly concave

in the middle; prothorax broader than long, finely and not very closely punctured—the horn (¢ ) rather

narrow, moderately long, parallel, finely margined to the tip, the tip rounded, the sides not serrate, the

crest moderately or very little raised, finely margined, narrowing from the base ; elytra rather long,

subparallel, finely and closely punctured, the punctuation finer towards the apex, the usual oblique

depression below the shoulders very shallow, the humeri distinct, the apices ( $) separately rounded ;

beneath, the prothorax excepted, piceous; antenne testaceous with the apical joints piceous-brown, or

* Examples of N. nuperus, Horn, were found by Morrison in Arizona, just beyond our northern

boundary.

NOTOXUS. 209

almost entirely piceous ; legs testaceous with the femora darker, the femora and the tarsi (the basal joint

excepted) piceous in one example; fifth ventral segment transversely concave in the middle behind, and

the apex truncate in the male.

Length 3 millim. (¢.)

Hab. Mexico, Guanajuato (Sallé), Jalapa (Hoge).

Two examples, both males. The Jalapa specimen is abraded and darker in colour,

and has the elytra a little more finely punctured and the thoracic horn more distinctly

margined at the tip; in the separately rounded apices of the elytra and in the form of

the fifth ventral segment in the male it agrees well with the one from Guanajuato *.

The shorter thoracic horn and the less distinctly margined crest, the separately rounded

apices and the non-angulated post-median fascia of the elytra, and the transversely con-

cave (not triangularly foveate) fifth ventral segment distinguish it from the same sex

of NV. ventralis, an insect occurring at the same localities; the thoracic crest is narrowed

from the base in NV. fraternus, in N. ventralis it is more oval in shape. Labelled

NV. fraternus, E. Dugés, in the Sallé collection.

Apparently allied to the North-American JV. talpa, La Ferté.

8. Notoxus truncatipennis.

Elongate, subparallel, piceous, shining, somewhat thickly clothed with moderately coarse decumbent hairs and

with scattered, more erect, rather longer hairs intermixed; the prothoracic horn rufous; the elytra with

a transverse narrow fascia on the middle of the disc towards the apex, and in one example also the sides

below the shoulders, reddish-testaceous, for the rest entirely piceous, a large, triangular, lateral, ante-

median patch and a postmedian transverse fascia (the ground-colour of which is partly testaceous) clothed

with whitish pubescence, the rest of the surface with brownish pubescence. Head comparatively large

and broad, closely and finely punctured, finely pubescent, with a few erect hairs in front, the front flat ;

prothorax broad and transverse, densely and somewhat coarsely punctured—the horn (2) long and

large, oval, finely margined to the tip, the sides not serrate, the crest moderately raised, finely margined,

narrowing from the base ; elytra long and subparallel, closely and rather coarsely punctured, the punctu-

ation finer towards the apex, the humeri distinct, the usual oblique depression below the shoulders shallow,

the apices (2) broadly and abruptly truncate; beneath piceous; antenne ferruginous, with the apical

joints piceous ; legs reddish-testaceous, the femora infuscate or piceous.

Length 34 millim. (9.)

Hab. Mexico, Guanajuato (Sallé).

Two worn examples, both females. Also labelled WV. fraternus, EK. Dugés, in the

Sallé collection. It cannot possibly, however, be the female of the species here

described under that name, the difference in the size and shape of the thoracic horn

being more than sexual; the head and thorax are also considerably broader; and the

thorax is densely and more coarsely punctured (the punctuation in WV. fraternus is

fine and rather sparse). ‘The thoracic horn is long and largely developed; the crest is

moderately raised, finely margined at the sides, without central carina. WV. truncati-

pennis is the only Central-American species known as yet with abruptly truncate elytra

in the female sex; JV. talpa, La Ferté, possesses a similar peculiarity.

* In Herr Hoge’s collection there is a female example of a Notoxus, from Ciudad in Durango, allied to this :

it comes nearer, however, to the North-American J. bifasciatus, La Ferté.

9. Notoxus crucifer. (Tab. IX. figg. 18, 18a, 2.)

Moderately elongate, subparallel, piceous, shining, somewhat thickly clothed with fine decumbent hairs ; the

prothorax with the extreme base and the horn reddish-testaceous; the elytra each with an oblique stripe

extending from the shoulders nearly.to the middle, and a transverse band considerably beyond the middle,

neither of which reaches the suture (the transverse band widening inwardly, obliquely cut off on its inner

side, and extending to the lateral margin, the oblique stripe widening posteriorly and extending along the

base), testaceous. Head finely and rather closely punctured, finely pubescent, with a few short erect hairs

in front, the front concave ; prothorax rather broader than long, finely and somewhat closely punctured—

the horn ( 2) long and parallel, moderately broad, feebly margined, the sides finely but distinctly serrate,

the tip oval, the crest raised, subparallel, the sides finely margined and crenulate; elytra moderately long,

subparallel, finely and closely punctured, the punctuation finer towards the apex, the usual oblique depres-

sion below the shoulders shallow, the humeri distinct, the apices ( 2 ) conjointly rounded ; beneath entirely

piceous; antenna ferruginous; legs reddish-testaceous, the femora darker.

Length 3 millim. (92.)

Hab. Guatemaa, San Gerénimo (Champion).

One rather worn female example. Closely allied to V. fraternus, from which it differs

in the thoracic horn being distinctly serrate at the sides and considerably longer (though

of similar width), and the crest more parallel. The apices of the elytra are conjointly

rounded, and very differently formed from those of the opposite sex of VV. fraternus or

of the same sex of WV. truncatipennis. The elytral markings, as in the two last-mentioned

species, are, no doubt, subject to considerable variation; the pubescence appears to

partake of the colour of the surface, though it is whitish at the sides before the middle.

10. Notoxus acuminatus. (Tab. IX. figg. 19, 194, 3.)

Elongate, narrow, piceous, thickly clothed with fine decumbent pubescence and with scattered, serially arranged,

long, erect hairs intermixed; the prothorax with the horn, and sometimes the sides and base, rufous; the

elytra variable in colour—usually with an oblique stripe extending from the shoulders downwards (not

reaching the middle, but continued along the base to the scutellum), an angulated fascia of variable

width beyond the middle (separated from the oblique stripe by an angulated, broad, median fascia of the

ground-colour), and the extreme apex (except in one specimen) testaceous, in one example testaceous with

a large piceous median patch (not reaching the suture, but laterally extending upwards to the shoulders)

and the scutellar and ante-apical regions infuscate. Head dull, finely and rather thickly punctured, the

front concave ; prothorax as long as broad, oval, densely and finely punctured, opaque—the horn long, rather

broad, a little narrower in the male, rounded at the tip, the sides serrate and rather feebly margined, the

crest about half the width of the horn in both sexes, moderately raised, its margin indicated by a row of

small tubercles ; elytra narrowing from the middle to the base, elongate-oval, closely and very finely

punctured, the punctures still finer towards the apex, the usual oblique depression below the shoulders

deep in both sexes, the humeri distinct, the apices produced and the sutural angles rather sharp in both

sexes; beneath piceous; antenne and legs testaceous, the intermediate joints of the former and the

femora and tibie often infuscate; fifth ventral segment broadly transversely concave and the apex trun-

cate in the male.

Length 23-3; millim. (¢ 2.)

Hab. GuateMaua, Quezaltenango 7800 feet (Champion).

Four male and two female examples. ‘This small narrow species differs from the

allied forms in the subacuminate apices of the elytra in both sexes. The elytra are

distinctly narrowed towards the base; the markings are variable, according to the

NOTOXUS. 211

predominance of the piceous or of the testaceous colour, though the same general

-pattern is visible in all the specimens ; the oblique depression is deep in both sexes ;

the erect hairs are long and rather numerous; and the pubescence partakes very much

of the colour of the surface from which it arises.

This insect appears to be peculiar to the Los Altos region of Guatemala; a male

example of a closely allied, but apparently distinct, species, from Chinautla, Guatemala

(Salvin), comes very near to it; but this latter, unfortunately, has lost its head and

thorax.

11. Notoxus hirsutus. (Tab. IX. figg. 20, 20 a, 2 .)

Elongate, parallel, densely clothed with very coarse decumbent pubescence and very long erect hairs; the head

and prothorax reddish-testaceous, the latter with the sides broadly infuscate; the elytra testaceous, with

a small spot on either side of the suture at the base, a median fascia (formed by two oblong spots on each

elytron, one at the suture and one on the disc lower down, the four together forming an interrupted

inverted V), a narrow ill-defined transverse band some distance before the apex, .and the sides below the

shoulders indeterminately, piceous. Head thickly and finely punctured, dull, the front concave ; pro-

thorax about as long as broad, densely and rugosely punctured, opaque—the horn ( @ ) very large and

broad, narrowing behind, granulate within, with four very coarse blunt teeth on each side, the sides a

little raised and the tip obtuse, the crest strongly and abruptly raised, sharply carinate in the middle, and

with the margins crenulate and sharply raised to the tip; elytra long and parallel, very closely and some-

what coarsely punctured, the punctures finer towards the apex, rather shining, the usual oblique depression

below the shoulders strongly impressed, the humeri distinct, the apices conjointly rounded and somewhat

obtuse, the sutural angles rather sharp; beneath fusco-testaceous ; legs and antenne testaceous, the knees

a little darker.

Length 44 millim. ( 9.)

Hab. Mexico, Presidio de Mazatlan (forrer).

The thoracic horn (fig. 20 a) in this insect is larger and more coarsely serrate at the

sides than in any other of the Central-American species. The pubescence is also very

coarse and dense, and the erect intermixed hairs long and numerous. The elytra are —

parallel in their basal half; the median fascia is formed of two oblong confluent spots

on each elytron, one at the suture and one on the disc lower down; the other mark-

ings are less distinct. The thorax is opaque and densely and rugosely punctured. The

still coarser pubescence, the form of the horn, and the elytral markings distinguish

N. hirsutus from N. mexicanus &c.

Sent to us in abundance by Morrison. In this species the anterior tibie of the male

are furnished with a triangular tooth on the inner side at the middle; the elytra have a

band, and the apex, black or piceous; the upper surface is thickly clothed with coarse

decumbent pubescence and long, coarse, erect hairs. The thoracic horn is very broad

and stout in the female, a little narrower in the male, sharply margined and more or

less serrate at the sides; the crest is abruptly elevated, strongly margined, and has a

carina down the middle *. The fifth ventral segment has a shallow triangular impres-

sion at the apex in the male. The apices of the elytra are conjointly rounded in both

sexes.

This is by far the commonest species of Notoxus in Central America, and at the same

time one of the most widely distributed of the whole of the American Heteromera.

More than half of the large number of specimens before me, including the whole of

those from the State of Panama, have the sides of the thorax and the sides of the

elytra from the base to the median fascia marked with black, a few also having a

narrow subapical fascia. Most of those from Mexico have these markings obliterated,

and the elytra merely with a spot on either side of the scutellum and a transverse

fascia a little beyond the middle, the fascia extending upwards at the suture.

N. monodon is distinguishable from most of the other species here described by the

median elytral fascia curving up towards the suture and there forming a broad quadran-

gular patch ; the pubescence is long and coarse, with long erect hairs intermixed ; the

anterior tibie are simple, and the elytra are conjointly rounded, in both sexes; the

thoracic horn is moderately long and broad, and varies a good deal in the form of the

margin &c. WN. cumanensis was chiefly separated from NV. monodon by La Ferté owing

to the difference of locality ; the characters given by him to distinguish it are derived

entirely from the thorax and are of a variable nature. The example from Antigua in

Sallé’s collection is labelled with the MS. name of NV. angustatus, La Ferté. Dr. Horn

* Omitted by our artist.

gives the length of V. monodon as 2'5-5 millim. ; our largest example does not measure

more than 4 millim. with the head extended. I have examined a typical specimen

from the United States, communicated by Dr. Horn.

14. Notoxus mexicanus. (Tab. IX. figg. 22, 22a.)

Elongate, subparallel, reddish-testaceous, somewhat thickly clothed with coarse, decumbent pubescence and

rather long erect hairs; the elytra testaceous, with a large spot on either side of the suture just below

the base, a curved fascia commencing at the sides beyond the middle and extending upwards along the

~ suture (sometimes nearly reaching the postbasal spots, in one example interrupted and less extended),

and an anteapical patch extending upwards along the suture, piceous. Head thickly and finely punctured,

dull, the front flat; prothorax transverse, very closely and finely punctured, slightly shining—the horn

long and parallel, narrow in the male, a little broader in the female, concave within, coarsely or moderately

coarsely serrate at the sides, and oval at the tip, the crest considerably raised, narrower than the horn,

and sharply margined to the tip, the margins feebly crenulate ; elytra long and subparallel, rather shining,

very closely and somewhat coarsely punctured, the punctuation finer towards the apex, the usual oblique

depression below the shoulders very faintly impressed, the humeri distinct, the apices conjointly rounded

and somewhat obtuse; beneath and the legs and antenne testaceous or fusco-testaceous; fifth ventral

segment unimpressed in the male.

Length 32-4 millim.

Hab. Muxico, Presidio de Mazatlan (Forrer), Acapulco and Iguala in Guerrero (Hége),

Guanajuato (Sallé).

Nine specimens, agreeing well with each other. More elongate and larger than

N. monodon; the thoracic horn longer, narrower, and parallel, the thorax itself much

more closely punctured. The thoracic horn resembles that of VV. anchora, Hentz, in

shape, but has a more prominent crest. The pubescence is shorter and finer than in

N. calcaratus. This is one of several Central-American species allied to MW. apicalis,

Lec., WV. monodon (Fabr.), and NV. calcaratus, Horn. Our figure is taken from the

Guanajuato example; this has the median fascia of the elytra interrupted.

15. Notoxus cristatus. (Tab. IX. figg. 23, 23 a, 3.)

Elongate, subparallel, reddish-testaceous, thickly clothed with long coarse decumbent pubescence and long erect

hairs; the prothorax with a black spot on either side of the crest; the elytra testaceous or reddish-

testaceous, with a spot on either side of the suture just below the base, a similar spot a little lower

down below the shoulder (obsolete in one example), a very strongly angulated median fascia, and a

narrower anteapical fascia (extending upwards along the suture and also with two branches extending

upwards at the sides), black. Head densely pubescent and with numerous long erect hairs at the sides

and in front, sparsely punctured, dull, the front slightly concave; prothorax broader than long, finely and

rather closely punctured, dull—the horn broad, a little narrowed behind, and margined and serrate at the

sides, the.crest abruptly elevated, sharply margined to the tip, and with a distinct carina down the middle,

the margins crenulate; elytra long and subparallel, rather shining, closely and finely punctured, the usual

oblique depression below the shoulders rather shallow, the humeri distinct, the apices a little produced,

the sutural angles rather sharp in the male, more obtuse in the female; beneath fusco-testaceous ; legs

and antenne testaceous; fifth ventral segment unimpressed in the male.

O14 | HETEROMERA.

and the thoracic horn narrower and more coarsely serrate laterally ; the fifth ventral

segment is unimpressed. This species is allied to V. calcaratus, from which it differs

in the much more strongly angulated elytral fascie, simple anterior tibiz in the male,

and sharper sutural angles of the elytra in both sexes. The elytral markings are very

sharply defined, the two fasciz both very strongly angulated and only separated by a

W-shaped mark of the ground-colour. The unimpressed head, different elytral mark-

ings, &c. distinguish WV. cristatus from WV. pueblensis.

16. Notoxus pueblensis. (Tab. IX. figg. 24, 24a.) |

Moderately elongate, subparallel, reddish-testaceous, somewhat thickly clothed with long coarse decumbent

pubescence and long erect hairs; the sides of the prothorax broadly piceous ; the elytra testaceous, with

a spot on either side of the suture below the base, an angulate fascia a little beyond the middle, a narrow

indeterminate anteapical fascia (almost obsolete in one example), and the sides below the shoulders,

piceous. Head rather sparsely pubescent, and with numerous long erect hairs in front, very finely and

somewhat closely punctured, moderately shining, the front longitudinally excavate in the middle;

prothorax broader than long, sparsely and finely punctured, rather shining—the horn moderately broad,

feebly margined and subserrate at the sides, the crest abruptly elevated, more distinctly margined, and

carinate down the middle, the margins crenulate; elytra subparallel, moderately long, shining, closely

and finely punctured, the punctuation finer towards the apex, the usual oblique depression below the

shoulders deep, the humeri distinct, the apices almost separately rounded in the male, conjointly so in the

female; beneath fusco-testaceous ; legs and antenne testaceous; fifth ventral segment unimpressed in

the male.

Length 22? millim. (¢ Q.)

Hab. Muxtco, Puebla (Sal/é).

Two examples: in one of these, the supposed male, the apices of the elytra are

less conjointly rounded than in the other; the horn is similarly shaped in both.

NV. puedblensis has the elytra marked very much as in WV. calcaratus; from which it

differs in the shorter and more scattered erect pubescence, the more shining surface,

the longer thoracic horn, the less closely and more coarsely punctured elytra, and the

simple anterior tibie in the male. The upper surface is more shining than in most of

the allied forms, and the dark markings of the elytra show an eneous lustre in certain

lights.

Twenty-one species of this very widely distributed genus have been described: of

this number three only are from the New World, two from the South-eastern States of

North America and one from California. "We now have to record one from the Pacific

coast of Guatemala. Mecynotarsus will probably be found eventually on the Atlantic

Bronze-black, rather shining; the head clothed with silvery-white pubescence and with numerous very long,

coarse, erect hairs at the sides and in front; the prothorax clothed with brownish pubescence on the disc

and coarser silvery-white scale-like pubescence at the sides, the sides with two or three long erect hairs ;

elytra each with a large oblong lateral patch of coarse silvery-white scale-like pubescence below the

shoulder, a smaller patch a little below the middle, and a still smaller one close to the suture at the apex,

for the rest sparsely clothed with fine brown pubescence.. Head densely and minutely punctured, broadly

longitudinally depressed in the middle in front; antenne slender, piceous-brown; prothorax globose,

nearly as long as broad, thickly and finely punctured—the horn moderately large, wider in the female than

in the male, very coarsely tridentate on each side, and with a strong blunt tooth at the apex, the crest

long and narrow, very little elevated, strongly margined to the apex, the margins serrulate ; elytra oval,

densely and coarsely punctured (the punctuation much coarser than that of the head or prothorax), the

humeri distinct but obtuse, the apices obtuse and slightly divergent in the male, more rounded in the female ;

legs testaceous or fusco-testaceous, the femora in great part piceous; beneath piceous’or piceous-brown,

opaque, densely and finely punctured, thickly clothed with coarse whitish pubescence; fifth ventral

segment depressed in the middle and emarginate at the apex in the male.

Length 13-2 millim. (¢ 9.)

Hab. GuateMata, Champerico (Champion).

Found in profusion on the sea-beach at Champerico on the Pacific coast. Allied to

M. elegans, Lec., from Florida, but with very differently arranged pubescence on the

elytra. The elytra are coarsely punctured, and have three lateral patches of coarse

silvery-white scale-like pubescence; the thoracic horn is coarsely tridentate on each

side, and has a coarse blunt tooth at the apex; the head is longitudinally depressed

and furnished with numerous long, coarse, erect hairs at the sides and in front.

Certain Australian species somewhat closely resemble WM. seanotatus.

TOMODERUS.

Tomoderus,; La Ferté, Monogr. Anthic. p. 94 (1848); Lacordaire, Gen. Col. v. p. 593.

Of the sixteen described species of Tomoderus, five only are from the New World—

two from the United States and three from Colombia. The genus is represented in

Central America by seven species, all of which are apparently new; two of these are

of very small size, less than 2 millim. in length. In a rather large undescribed species

from Colombia, of which a single example is contained in Mr. F. Bates’s collection,

labelled ZTomoderus pallidicornis, Schauf., the shoulders of the elytra are completely

effaced (the elytra, in consequence, being more ovate) and the body is apterous; this

insect is, perhaps, generically distinct from Tomoderus.

The Central-American species may be tabulated thus :—

Prothorax deeply canaliculate ; species comparatively large.

Elytra with a large and deep post-basal depression. . . . . = + + excavatus.

Elytra with a very shallow post-basal depression . . » + « « « canaliculatus.

Prothorax at most obsoletely or very finely canaliculate (the groove some-

times confined to the constricted part); species smaller.

Elytra with a large deep post-basal depression extending outwards to the oe

humeri; basal joints of antenne slender and moderately moniliform . complanatus.

1. Tomoderus excavatus. (Tab. IX. tig. 26, 2.)

Short, broad, convex, shining, dark reddish-brown, the elytra (except at the base and apex) piceous or piceous-

brown; the head and prothorax very sparsely pubescent, the elytra somewhat thickly clothed with longer

and coarser semierect fulvous hairs. Head transverse, large, smooth, the eyes small and not prominent ;

antenne rather short, moderately stout, widening outwardly, joints 9 and 10 strongly transverse and

broader than 8, 11 about twice as long as 10, ovate, acuminate, 1 and 2 ferruginous, 3-8 black, 9-11

testaceous ; prothorax narrower than the head, one half longer than broad, smooth, very strongly

constricted behind the middle (the posterior portion nearly as wide at the base as the anterior portion),

the disc longitudinally suleate (deeply so on the posterior portion, more finely and shallowly so on the

anterior portion, the groove on the latter confined to the most elevated part, and not extending to the

apex); elytra broad and short, more than twice as wide as the prothorax, rather obtuse behind, a little

dilated at the sides about the middle, each with a large and deep transverse or oblique depression on the

disc below the base, and irregular rows of somewhat distantly placed punctures, the punctures coarser

and distinct at the base, fine and shallow beyond the basal depression, and becoming very faint’towards _

the apex; beneath piceous; legs testaceous or fusco-testaceous, the femora darker in the middle, the latter

moderately clavate.

Length 23 millim. (92.)

Hab. Guatemala, Chiacam and Senahu in Vera Paz (Champion).

Two examples, both females. Allied to the Colombian 7. signaticornis, La Ferté ;

but differing from it in the very deep post-basal depression (transverse in one example,

oblique in the other) of the elytra, and in the deeper longitudinal sulcature of the

posterior part of the thorax. The antenne are very similarly coloured.

2. Tomoderus canaliculatus.

Short, broad, convex, shining, pale castaneous, the elytra lighter at the apex, the head and prothorax very

sparsely pubescent, the elytra thickly clothed with longer and coarser semierect fulvous hairs. Head and

antenne almost as in 7’. excavatus, the antenne with joints 1 and 2 testaceous, 3-8 piceous-brown, and

9-11 flavo-testaceous ; prothorax very much as in 7’. excavatus, but with the longitudinal median groove

deep on both the anterior and the posterior portions (the groove on the anterior portion deeper and longer

than in 7. excavatus, but not reaching the apex); elytra longer than in 7. excavatus, a little dilated at the

sides before the middle, with only a very shallow transverse depression on the disc below the base, the

punctuation fine and shallow (much finer at the base than in 7’. ewcavatus), becoming almost obsolete

behind, the punctures forming irregular rows; beneath reddish-brown, the last two ventral segments

flavo-testaceous; legs flavo-testaceous, the femora a little darker at the base, the latter moderately

clavate.

Length 22 millim. (¢.) ‘

Hab. Nicaracua, Chontales (Janson).

One male example. This insect agrees closely with La Ferté’s description of

TL. signaticornis * ; the thoracic groove, however, is much deeper (apparently as distinct

as in the eastern 7’. su/cicollis, La Ferté) and the elytral punctuation finer. Compared

with 7’. excavatus, the thorax is more deeply sulcate on the anterior portion, and the

elytra are longer, much more finely punctured at the base, and have only a very shallow

post-basal depression. ‘The last dorsal segment is truncate at the apex.

8. Tomoderus complanatus.

Short, moderately broad, rather depressed, sbining, reddish-brown, the elytra reddish-testaceous or testaceous

with the disc of each indeterminately infuscate beyond the middle; the head and prothorax very sparsely,

the elytra more thickly, clothed with long, semierect, silky pubescence. Head transverse, smooth,

obsoletely canaliculate on the vertex ; eyes very small, not prominent, very finely granulated ; antenne

short, slender at the base and thickening outwardly, the joints strongly moniliform, 9 and 10 strongly

transverse, 1 ferruginous, 2-10 black, 11 testaceous; prothorax narrower than the head, about one fourth

longer than broad, smooth, very strongly constricted behind the middle, the posterior portion a little

narrower at the base than the anterior portion, both finely canaliculate; elytra more than twice as broad

as the prothorax, short, rather depressed, widest a little before the middle, the usual post-basal depression

large and rather deep (extending outwardly to the humeri), the surface confusedly punctured, the punctures

moderately fine at the base and becoming very much finer and shallower beyond the middle; beneath

dark reddish-brown ; legs testaceous, the femora moderately clavate.

Length 2} millim.

Hab. Mexico, Jalapa (Hége).

Two examples. The small and non-prominent eyes, the finely but distinctly canali-

culate thorax, and the large post-basal depression of the elytra separate 7. complanatus

from 7’. monilicornis and T. brevicornis. The elytra are more finely punctured at the base

than in 7. brevicornis, and the post-basal depression is much more extended than in

T. monilicornis; the punctuation is confused, and shows scarcely any trace of a linear

arrangement. ‘The vertex is distinctly canaliculate in one example, very obsoletely so

in the other. The thorax is considerably shorter than in 7. monilicornis, and the

anterior portion is rather broader than the posterior portion (more distinctly so in one

specimen). The North-American 7. interruptus, La Ferté, is an allied but _consider-

ably larger species. |

4. Tomoderus monilicornis.

Closely allied to 7’. brevicornis. The head and prothorax pitchy-black, the former testaceous in front, the elytra

castaneous ; the eyes rather prominent; the antenne stouter than in 7’. brevicornis (the basal joints especi-

ally), joints 2-8 more strongly moniliform and 9 and 10 more strongly transverse, piceous, the basal joint

a little lighter, 8-11 flavo-testaceous ; the prothorax a little longer than in 7’. brevicornis (about one half

longer than broad), the constricted part very distiftctly canaliculate, the groove extending to the posterior

but not to the anterior portion ; the elytra shorter and a little more convex than in 7’. brevicornis, more than

twice as broad as the prothorax, with a rather deep transverse depression on either side of the suture

below the base (the depressions almost confluent at the suture, and not extending outwards beyond the

third row of punctures), the punctures distinctly arranged in rows towards the base, moderately coarse

anteriorly, and becoming very much finer beyond the middle; beneath coloured as above; legs entirely

flavo-testaceous, the femora moderately clavate.

Length 27 millim.

Hab. Mzxico, Cordova (Sallé). :

One example, apparently a male. The black head and thorax, the stouter and more

moniliform basal joints of the antenne, the more deeply canaliculate constricted part of

the thorax, and the deeper post-basal depression and the more linear arrangement of

the punctures of the elytra distinguish 7. monilicornis from T. brevicornis.

5. Tomoderus brevicornis. (Tab. IX. fig. 27.)

Short, moderately broad, rather convex, shining, brownish-testaceous or pale castaneous, the head, or the head

and thorax, reddish-brown; the head and prothorax very sparsely, the elytra more thickly, clothed with

long, semierect, silky pubescence. Head transverse, smooth; the eyes slightly prominent, somewhat

- eoarsely granulated; antenne short, extending very little beyond the base of the prothorax, thickening

outwardly, the basal joints (the first excepted) slender, and the ninth and tenth strongly transverse,

piceous-brown or brown, with the three basal joints and the apical one, two, or three testageous ;

prothorax narrower than the head, about one third longer than broad, smooth, very strongly constricted

behind the middle, the posterior portion only a little narrower at the base than the anterior portion, the

constricted part distinctly canaliculate and in some examples the anterior and posterior portions obso-

letely so; elytra more than twice as broad as the prothorax, rather short, slightly rounded at the sides,

widest at the middle, the usual post-basal depression obsolete or very faint, the surface irregularly

punctured, the punctures deep and coarse at the base and gradually becoming finer towards the apex;

beneath coloured as above ; legs flavo-testaceous or testaceous, the femora moderately clavate.

Length 23-23 millim. (¢ 9.)

Hab. Mexico, San Juan Bautista in Tabasco (Hége), Teapa (coll. Oberthiir, H. H.

Smith); Guatemaua, El Reposo, Zapote, Tamahu, Chiacam (Champion).

Not uncommon in Guatemala, on both the Atlantic and Pacific slopes; four specimens

only from §.E. Mexico. Very much smaller than 7. canaliculatus; the thorax similarly

shaped, but, at most, very obsoletely canaliculate (the constricted part only, as a rule,

being channelled); the elytra more coarsely punctured at the base, the punctures

showing a tendency to a linear arrangement; the legs entirely flavo-testaceous; the

antennee more slender towards the base. The thorax is longer and the anterior

portion is relatively narrower than in the North-American 7. interruptus, La Ferté,

and 7’. constrictus (Say); in the majority of the specimens the anterior and posterior

portions are without trace of amedian channel. 7. hirtulus, La Ferté, from Colombia,

the type of which I have examined, is an allied species, but is a larger and broader

insect than 7. brevicornis, and also differs in the form of the antenne. An example of

the latter bears the MS. name of 7. flavipes, Deyr., in M. Oberthiir’s collection.

TOMODERUS. 219

6. Tomoderus exiguus.

Short, moderately broad, rather convex, shining, pale castaneous or reddish-brown, the head in one example a

little darker; the head and prothorax very sparsely, the elytra more thickly, clothed with long, fine,

semierect pubescence. Head transverse, smooth, obsoletely canaliculate on the vertex, the eyes very

small; antenne rather short, slender, thickening a little outwardly, and with joints 9 and 10 strongly

transverse, black or piceous, the basal joint usually a little lighter, the apical joint (except in one example)

testaceous; prothorax narrower than the head, about one fourth longer than broad, very strongly

constricted behind the middle, the posterior portion very little narrower at the base than the anterior

portion, both (when viewed in certain lights) finely canaliculate ; elytra short, more than twice as broad

as the prothorax, rather convex, widest a little before the middle, the usual post-basal depression exceed-

ingly shallow or nearly obsolete, the surface confusedly and somewhat coarsely punctured, the punctuation

becoming much finer beyond the middle; beneath coloured as above; legs testaceous or ferruginous, the

femora sometimes a little darker, the latter moderately clavate.

Length 12-12 millim. (¢ 9.)

Hab. Gvuatemata, Senahu in Vera Paz 2800 feet (Champion).

Six examples. This minute species resembles 7. brevicornis, from which it differs in

its much smaller size and more slender antenne. The punctuation of the elytra is coarse

and confused on the basal half, and the post-basal depression is very faint (as in

T. brevicornis); the antenne are slender and piceous in colour, the apical joint usually

testaceous and the basal joint ferruginous; the thorax is very finely canaliculate, and

the top of the vertex also. The following species is more nearly allied to it.

7. Tomoderus brevis.

8 Short, broad, convex, shining, unicolorous reddish-testaceous or pale castaneous, the head and prothorax with

~ < a few very fine erect hairs, the elytra sparsely clothed with long, fine, semierect pubescence. Head

transverse, smooth, the eyes very small; antenne rather short, slender, thickening outwardly, joints

9 and 10 strongly transverse, 1 and 2 testaceous, 3-6 or 3-7 fusco-testaceous, and 7-11 or 8-11

flavo-testaceous, sometimes testaceous with the apical four or five joints yellower; prothorax narrower

than the head, about one third longer than broad, very strongly constricted behind the middle, the posterior

portion a little narrower at the base than the anterior portion, the latter usually (when viewed in certain

_ lights) obsoletely canaliculate in front; elytra short, at least three times as broad as the prothorax, convex,

without post-basal depression, moderately rounded at the sides, widest at the middle, the surface very

sparsely, confusedly, and finely punctured, the punctures becoming very much finer beyond the middle, the

sides almost smooth ; beneath coloured as above ; legs testaceous or flavo-testaceous, the femora mode-

rately clavate.

Length 14-13 millim. (¢ 9.) ©

Hab. Guatemata, Las Mercedes, Cerro Zunil, San Isidro, Zapote (Champion);

Panama, Volcan de Chiriqui 3000 feet (Champion).

Many specimens, both from Guatemala and the State of Panama. Of the same size as

T. exiguus ; but differing from it in the colour of the antenne, the almost unchannelled

thorax, and the shorter, broader, and more convex elytra, the latter much more finely

and sparsely punctured, and without post-basal depression. In the Chiriqui specimens

and in one of those from Zapote the antenne are testaceous with the apical four or five

joints yellowish ; in all the others the intermediate joints are more or less infuscate.

T.. exiguus appears to be confined to the Atlantic, and T. brevis to the Pacific slope.

Anthelephilus (Hope), La Ferté, loc. cit. p. 65.

Formicilla, Leconte, Ann. Lyc. New York, v. p. 152 (1852).

Numerous species of this widely-distributed genus have been described. The

American representatives have the femora less strongly clavate than in the Old-World

forms. One species is now recorded from our region, this making the fourth known

from the American continent.

1. Formicomus gracilipes. (Tab. X. fig. 1.)

Bright reddish- or flavo-testaceous, very smooth and shining; the elytra with a broad transverse fascia at or

just before the middle (usually widening outwardly and not reaching the suture, sometimes extending

completely across, in rare examples almost obsolete), a broad transverse anteapical fascia extending

forwards at the suture (occasionally confluent with the median band, and sometimes occupying the whole

of the apical portion), and in rare examples the shoulders or the base, narrowly, piceous ; the upper surface

clothed with scattered exceedingly long, yellowish, erect, bristly hairs, those on the elytra serially arranged.

Head large and elongate, rounded at the sides behind, with a few widely scattered fine setiferous punctures ;

eyes black, coarsely granulated, rather large, moderately prominent; antenne testaceous, elongate, slender

at the base and thickening outwardly, the apical three joints distinctly stouter than the preceding ; pro-

thorax nearly twice as long as broad, very much narrower than the head, the sides much rounded before

and very strongly but not abruptly constricted behind the middle, the anterior portion transversely convex,

the posterior portion dilated laterally at the base, the flanks grooved in the narrowest part, the neck very

sharply defined, the surface with a few fine setiferous punctures ; elytra subovate, subtruncate at the base

and rounded at the apex, flattened on the disc (or with a very shallow transverse depression) below the

base, the humeri obtuse but distinct, the surface with a few widely scattered very fine punctures (in some

specimens almost obsolete, in others more distinct); legs entirely testaceous, long and slender, the femora

very feebly clavate; wings fully developed or merely rudimentary ; fifth ventral segment truncate in

the male.

Length 24-22 millim. (3 9.)

Hab. Mexico, Cordova (Sallé), Vera Cruz (Hoge); GuatemMaLa, Champerico, Paso

Antonio (Champion).

Found in abundance by myself on the sea-shore at Champerico on the Pacific coast

and by Herr Hoge at Vera Cruz on the Atlantic coast, and also occurring inland.

F, gracilipes is very closely allied to the North-American F. scitulus, Lec., a specimen

of which from Florida has been communicated by M. Sallé; but differs from it in the

more prominent humeri and less ovate elytra and in the longer legs and antenne.

F’, leporinus, La Ferté, from Brazil, the type of which I have examined, is also an allied

form, but differs from both these in its longer thorax and in the coloration of the elytra.

F. mundus, Lec., is stated to have a large and distinct post-humeral depression and the

thorax tripunctate at the base. In most of the Vera Cruz specimens the wings are

rudimentary, but others from the same locality have fully developed wings as in all the

Guatemalan examples and in the one from Cordova. The mesosternum (as noted by

La Ferté in his description of F. leporinus) is somewhat angularly extended on either

side in front, this part being clothed with very long erect bristles and visible from

above. The elytra are almost smooth in some examples, and distinctly punctured

in others.

Acanthinus, La Ferté, Monogr. Anthic. p. 186.

Ischyropalpus, La Ferté, loc. cit. p. 141.

This genus already contains upwards of 400 described species, and is represented in

almost every part of the world.’ Leconte, in his monograph of the North-American

species [Proc. Acad. Phil. vii. pp. 95-103 (1852)] enumerated fifty, of which ten were

unknown to him; and since the publication of this the genus seems to have been

almost ignored by American Coleopterists, though five species from California have

subsequently been described by Boheman (Kongl. Svenska Freg. Eug. Resa, Ins. pp. 104—

106), without the slightest reference to previously known forms *. We have now to

enumerate exactly the same number of species (fifty) from within our limits, of which

twenty-nine are described as new ; two only have hitherto been recorded from Central

America. Thanks to the kindness of M. Réné Oberthiir, I have been enabled to study

the La Ferté collection of Anthicide (which is still in an excellent state of preservation),

and by this means to identify very many of our species; Dr. Horn and M. Sallé have

also been kind enough to communicate named representatives of various North-

American forms. I have also studied, for the purposes of this work, Marseul’s very

extensive collection of Anthicide now in the Paris Museum. Many of the species of

this genus are widely distributed, some extending from the United States into Central

America, and others from Brazil &c. northwards to Guatemala or Southern Mexico;

this may be due to their activity, combined with, apparently, carnivorous habits. ‘The

majority of the Central-American representatives do not exhibit any marked peculiarity

from those of Tropical South America or from those of the United States; two

species, however, A. bactrianus and A. tumidicollis, differ from all others of the genus

previously known in having the posterior portion of the thorax gibbous. The

characteristic ‘Tropical-American subgenera Acanthinus and Ischyropalpus, La Ferté,

are both represented within our region—the former by four, the latter by one

species. A. albicinctus, A. bituberculatus, A. dromedarius, &c. are also characteristic

of the warmer regions of the New World; and the A. odscurus-group of the United

States, Central America, and the northern part of South America. Two species,

A. foveiventris and A, crassicornis, have poner: stout antenne, and A. clavicurnis

Peruvian forms being recorded by Boheman from Panama or the Sandwich Is. !

has these organs very distinctly clavate. A. dituberculatus has a stout conical tubercle

on either side of the suture at the base. Good specific characters are sometimes to be

found in the form of the fifth ventral segment of the males: this segment in the

majority of our species is unimpressed, but in some of them it is foveate or transversely

concave in the middle ; the apex is usually truncate, sometimes emarginate.

The American synonymy only is quoted.

In this peculiar little species the thorax has a deep transverse groove extending com-

pletely across the narrowest part, the anterior portion being globose and the posterior

portion subparallel; and the elytra have a very deep and large post-basal depression,

the space in front of this on either side of the suture being much swollen. The

ashy-pubescent transverse fascia occupying the basal depression ; the upper surface is

very shining, with only a few very widely scattered fine punctures, the punctures each

bearing a long erect hair; the head is transverse, the eyes rather large; the antenne

are distinctly thickened outwardly and somewhat clavate, and have the four or five basal

joints testaceous and the others piceous-brown or black; the legs are piceous or

brownish, with the tarsi more or less testaceous. ‘The male has the fifth ventral

segment very deeply triangularly emarginate.

Our specimens are blacker in colour than those contained in the La Ferté collection,

in which both sexes are represented. A specimen from Caracas in the La Ferté

collection is labelled A. sallei, mihi, ined. .

A. gibbicollis, La Ferté, from Venezuela, is an allied species, not yet received from

within the limits of our fauna.

2. Anthicus bituberculatus. (Tab. X. figg. 2; 2a, profile.)

Anthicus omoplatus, Deyr. in litt.

Moderately elongate, black or brownish-black, the head, prothorax, and base of the elytra sometimes pitchy-

red, the elytra with a transverse ashy-pubescent testaceous or yellowish fascia (not reaching the suture and

sometimes indistinct) occupying the post-basal depression; the entire upper surface very shining and

furnished with widely scattered long erect hairs. Head nearly as long as broad, rounded at the sides

behind, shallowly and irregularly punctured and clothed with fine greyish pubescence in front, smooth and

glabrous posteriorly, the eyes moderately large, the palpi piceous; antenne with the apical four joints

widened, joints 9-1] wider than 8, 1—4 or 1-5 flavous or testaceous, the rest black; prothorax very much

narrower than the head, longer than broad, very strongly constricted at the sides behind the middle and

with a transverse groove extending across the disc in the narrowest part, the anterior portion globose and

strongly gibbous, the posterior portion very short and not swollen, the base feebly margined, the flanks very

deeply excavated, the surface with a few fine widely scattered punctures; elytra rather short, widest

about the middle and narrowing in front, with a very deep transverse post-basal depression, and somewhat

gibbous behind this, the basal portion on cither side of the suture conically raised in both sexes, the

humeri prominent, the surface smooth or with irregular rows of fine shallow punctures towards the base ;

legs piceous or brownish, the tarsi more or less testaceous; fifth ventral segment deeply triangularly

depressed in the middle behind and the apex emarginate in the male.

Hab. Muxtco, Teapa (coll. Oberthiir); GuarumaLa, Paso Antonio (Champion) ;

Nicaragua, Chontales (Janson); Panama, Volcan de Chiriqui 3000 feet (Champion).

Ten examples. Closely allied to A. albicinctus, from which it may be at once

separated by the prominent conical elevation on either side of the base of the elytra

(this is very distinct when the elytra are viewed from behind or from the side). The

head is less transverse; the transverse groove of the thorax is shallower (the narrow

basal portion appearing less raised); and the elytra sometimes have irregular rows of

fine shallow scattered punctures towards the base. The male, as in the same sex of

A. albicinctus, has the fifth ventral segment emarginate.

A. vinculatus, La Ferté, from Cumana, has the elytra somewhat similarly tuberculate

at the base; this species, however, has a very differently shaped thorax.

3. Anthicus clavicornis. (Tab. X. figg. 3; 3a, profile.)

Moderately elongate, black or brownish-black, the head or the head and prothorax sometimes pitchy-red, the

elytra each with a transverse flavous fascia below the base (occupying the basal depression, and sometimes

nearly extending to the suture and to the lateral margin); the upper surface very shining and with a few

fine widely scattered erect hairs. Head as long as or longer than broad, convex, rounded at the sides

behind, very sparsely and finely punctured and clothed with fine longitudinally arranged appressed pubes-

cence, the eyes very prominent, the palpi varying in colour from piceous-brown to fusco-testaceous ;

antenne distinctly clavate, the apical three joints considerably widened, joints 1-3 or 1-4 flavo-testaceous,

the rest black ; prothorax a little longer than broad, narrower than the head, strongly gibbous anteriorly,

the sides rounded before and deeply constricted behind the middle and thence to the base straight (in some

specimens one or two very short teeth are visible at the broadest part, and the sides in these appear to: be

more angularly dilated), the flanks with a short but deep excavation, the base finely margined, the disc

(viewed laterally) cylindrical and uninterrupted behind and abruptly declivous in front, the surface very

finely and very sparsely punctured ; elytra rather short, rounded at the sides about the middle and

narrowing in front, obtuse behind, with a deep transverse: post-basal depression and convex or almost

gibbous behind this, the basal portion slightly swollen, the humeri prominent, the surface distinctly

striate-punctate to about one-third from the base and thence to the apex obsoletely so or almost smooth ;

legs piceous, the femora usually paler at the base, the tarsi flavous, the femora distinctly clavate; fifth

ventral segment broadly and shallowly emarginate in the male.

Nine examples. This insect inhabits both the Atlantic and Pacific slopes of Guate-

mala, extending along the Atlantic slope northwards to S. Mexico. It has much the

facies of A. albicinctus and A. bituberculatus, from either of which the very differently

formed thorax at once distinguishes it: in A. clavicornis the disc is not interrupted

by a transverse groove. The eyes are very prominent; the antenne are clavate; the

thorax is strongly gibbous in front; the elytra are short and convex, and have a deep post-

basal depression, the depression occupied by a flavous fascia, the surface striate-punctate

towards the base. The head is partly clothed with long, fine, appressed pubescence,

and appears at first sight to be longitudinally strigose. The thorax usually has one or

two very short indistinct teeth at the widest part. The hind tibie are simple in both

sexes. A. clavicornis is perhaps nearest allied to A. vinculatus, La Ferté, from which

it may be easily recognized by the clavate antenne, the more prominent eyes, the more

gibbous anterior portion of the thorax, and the non-tuberculate elytra. A. impressi-

pennis, La Ferté, from Texas, the type of which is not contained in this author's collec-

tion, is apparently an allied species, but differs in being more elongate &c.; this insect

was unknown to Leconte.

(Janson).— VENEZUELA, Cumana!.

A. dromedarius, La Ferté, described from a single abraded example, is one of the

commonest species of the genus in Central America. Our specimens vary in colour

from black to castaneous, the head and prothorax being often more or less reddish ; the

elytra have a transverse fascia of variable size a little below the base (in some examples

occupying the whole of the base) and an oblique one (rarely reaching the suture) below

the middle, and the base on either side of the scutellum, testaceous or flavous; the legs

vary in colour from pitchy-brown to flavo-testaceous, but the tibiee are invariably dark (a

character particularly mentioned by La Ferté, and especially noticeable in light-coloured

examples) ; the antenne have usually the outer joints piceous or brownish and the basal

joints testaceous, in one or two examples, however, they are entirely testaceous. The

head and thorax are densely and minutely punctured (more sparsely so in some

examples), the former usually smoother and more shining behind; the head is rather

long, rounded at the sides behind, the eyes large; the thorax is transversely convex

anteriorly and strongly constricted behind the middle; the elytra are very shining

and almost smooth, and have a very deep transverse post-basal depression, the basilar

portion being tubercularly raised on either side of the suture and the humeri swollen

and prominent, the depression (which is usually more than covered by the transverse

fascia) clothed with fine ashy pubescence and the oblique post-median fascia also finely

pubescent.

The darkest specimens have the femora, as well as the tibiae, piceous. In the male

the fifth ventral segment is broadly triangularly depressed in the middle behind, and

the apex is truncate.

The examples from Chacoj-and Senahu agree exactly with La Ferté’s type from

Cumana, with which I have compared them ; the type is a male.

Labelled A. gibbicollis, Deyr., in the Sallé and other collections.

ANTHICUS. 227

5. Anthicus punctatissimus.

Elongate, ferruginous, subopaque ; the elytra shining, fulvo-testaceous, each with an indeterminate transverse or

oblong brownish median patch (not reaching the lateral margin and distant from the suture), the apex in

one example darker; the upper surface very finely pubescent. Head not very convex, as long as broad,

rounded at the sides behind, very densely and minutely punctured, the eyes small, finely granulated, and not

prominent ; antenne slender, entirely testaceous ; prothorax longer than broad, a little narrower than the

head, rounded at the sides before and strongly constricted behind the middle, the anterior portion trans-

versely convex, the posterior portion cylindrical, the flanks deeply excavated, the base finely margined,

the surface sculptured like that of the head; elytra moderately long, somewhat rounded at the sides about

the middle, subparallel and narrower anteriorly, with a deep post-basal depression and convex beyond this,

the basilar portion gibbous on either side of the suture, the humeri rather prominent, the surface densely

and minutely punctured throughout ; legs entirely testaceous ; fifth ventral segment deeply triangularly

depressed in the middle behind and the apex truneate, and the posterior tibie slightly sinuate, in

the male. ,

Length 25 millim. (<¢.)

Hab. MExico, near the city (Hége).

Two male examples, both abraded. The densely and minutely punctured elytra

distinguishes this species at once from A. dromedarius. The depression on the fifth

ventral segment is deeper and narrower than in the same sex of that insect, and the

head is more finely and more densely punctured. The elytral markings are indistinct ;

they show a tendency to assume the pattern of A. dromedarius.

A mutilated specimen from Chilpancingo probably belongs to the same species.

6. Anthicus septemnotatus. (Tab. X. figg. 5; 5a, profile.)

Elongate, piceous or piceo-ferruginous, subopaque; the elytra shining, piceous or piceous-brown, with a rather

large spot on either side of the scutellum at the base, an oblique angulated stripe below the shoulders

(variable in size—sometimes extending to the suture and continued along it to the basal spot, sometimes

reduced to a lateral spot), a broad oblique stripe considerably beyond the middle (sometimes confluent with

the opposite one at the suture, sometimes not reaching it), and a common apical patch, flavo- or fulvo- —

testaceous ; the upper surface clothed with short, widely scattered, erect hairs. Head large, broader than

long, a little dilated at the sides behind, finely rugulose, dull, the eyes large, coarsely granulated, and

rather prominent ; antenne testaceous, the apical three joints more or less infuscate ; prothorax longer than

broad, narrower than the head, rounded at the sides before and strongly constricted behind the middle, the

anterior portion transversely convex, the posterior portion cylindrical, the flanks deeply excavated, the

base obsoletely margined, the surface finely rugulose; elytra moderately long, parallel in front, a little

dilated at the middle, with a deep post-basal depression and somewhat convex beyond this, the basilar

portion gibbous on either side of the suture, the humeri rather prominent, the surface sparsely, finely, and

confusedly punctured (the punctuation denser in the post-basal depression and finer at the apex); legs

rather stout, the apical half of the femora and the base of the tibie more or less infuscate; fifth ventral

segment triangularly depressed in the middle behind, and the apex truncate, in the male.

Length 23-3 millim. (¢ 2.)

Hab. Mexico, Teapa in Tabasco (H. H. Smith); Guatemaua, El Tumbador, Volcan

de Atitlan, Zapote (Champion).

Seven examples. The shining and sparsely punctured elytra distinguishes this insect

at a glance from A. guinguemaculatus and its allies; the more elongate shape, larger

size, and very distinct elytral punctuation separate it from A. dromedarius.

Our specimens agree exactly with La Ferté’s description and type, except as regards

the form and sculpture of the head. From a careful examination of the type, I have

not the slightest doubt that the head (which is detached and gummed down separately)

does not belong to the specimen described, and that it appertains to a totally different

species. A renewed description is given from the Central-American examples :—

Elongate, ferruginous, opaque; the elytra testaceous or flavo-testaceous, with an oblique humeral patch, a

common transverse median fascia (widened at the suture and laterally), and a narrow anteapical fascia

(formed by an oblique stripe on each elytron, these being confluent at the suture and extending up it to

the median fascia), piceous or piceous-brown ; the upper surface clothed with very short, fine, silky pubes-

cence, and with a few widely scattered short erect hairs. Head transverse, broad, somewhat dilated at

the sides behind, moderately convex, finely rugulose and opaque throughout, the eyes large, coarsely

granulated, and prominent ; antenn# about reaching the base of the prothorax, rather slender, testaceous,

the apical three joints slightly infuscate ; prothorax narrower than the head, longer than broad, rounded

at the sides before, and strongly constricted behind the middle, the anterior portion transversely convex,

the posterior portion subcylindrical, the flanks with a deep oblique excavation (scarcely visible from above),

the base very finely margined, the neck very sharply defined, the surface finely rugulose, the disc in some

specimens obsoletely canaliculate behind; elytra moderately long, the sides a little rounded about the

middle, parallel and narrower anteriorly, broadly transversely depressed below the base and feebly convex

beyond this, the basilar portion very little swollen, the humeri rather prominent, the surface very densely

and minutely punctured; beneath ferruginous ; legs entirely testaceous ; fifth ventral segment truncate

and with an exceedingly deep triangular excavation in the middle behind (extending forwards nearly to the

apex of the preceding segment) in the male.

Length 2$ millim. (¢ 2.)

Kight examples. If piceous be taken as the ground-colour, the elytra may be said to

have a broad oblique fascia before and another behind the middle (the latter not

reaching the suture, and the former extending up it to the base), and a common apical

patch, flavo-testaceous. The excavation in the middle of the fifth ventral segment in

the male is very sharply defined. The following two species are closely allied.

Anthicus concinnus, La Ferté, Monogr. Anthic. p. 115°.

Hab. Guiana, Cayenne!; Brazit, Bahia !.

Var.

Closely allied to A. quinquemaculatus ; the head, eyes, antenne, and prothorax as in that species, the head and

prothorax sometimes in great part piceous; the elytra similarly sculptured, the piceous colour more

extended—the median fascia more sharply angulated and only separated from the more extended oblique

humeral stripe (this being sharply excised on its lower edge below the shoulders) by a W-shaped mark of

_ ANTHICUS. 229

the testaceous ground-colour, the ante-apical fascia shaped as in A. quinquemaculatus but usually more

extended ; legs testaceous, the apices of the femora often infuscate; fifth ventral segment unimpressed,

truncate at the apex, and the apex furnished with a short tooth on either side of the middle, in the

male.

Length 23 millim. (3 9.)

Hab. British Honpuras, Belize (Blancaneaux); Nicaragua, Chontales (Janson).—

Souta America, Santiago (coll. La Ferté).

Six examples received from Central America agree very nearly with La Ferté’s

description and types of A. concinnus, except as regards the colour of the apex of the

elytra. In La Ferté’s collection, however, there is a specimen (not mentioned in his work)

placed under this name (labelled as from Santiago *) similar to the Central-American

examples. I accordingly treat these as a variety of the same species. In the type of

A. concinnus the entire apex of the elytra is piceous; in the variety the piceous colour

is less extended and in the form of an oblique ante-apical fascia.

9. Anthicus pulchellus. (Tab. X. fig. 8.)

Moderately elongate, ferruginous, opaque; the elytra rather shining, piceous, with a common angulated

transverse fascia below the base (extending upwards along the suture and connected with a small

basal spot), a narrow curved oblique stripe beyond the middle (not reaching the suture), and a small

apical patch (from which a short somewhat oblique branch usually extends upwards on either side of the

suture), testaceous ; the upper surface clothed with very short, fine, silky, appressed pubescence and with

rather numerous erect bristly hairs, those on the elytra serially arranged. Head strongly transverse,

somewhat dilated at the sides behind, moderately convex, finely rugulose and opaque throughout, the eyes

large and prominent ; antennz testaceous, the apical three joints infuscate and a little wider than the

others ; prothorax longer than broad, narrower than the head, rounded at the sides before and strongly

constricted behind the middle, the anterior portion transversely convex, the posterior portion subcylindrical,

widened a little at the base externally, the flanks with a deep groove, the base obsoletely margined, the

surface finely rugulose ; elytra rather short, the sides somewhat rounded about the middle, subparallel

and narrower anteriorly, rather deeply transversely depressed below the base and moderately convex

beyond this, the basilar portion gibbous on either side of the suture, the humeri obtuse but rather promi-

nent, the surface densely and minutely punctured, and with regular series (four on each elytron) of distinct

scattered setiferous punctures extending from the base to the apex; legs entirely pale testaceous, the

femora slightly clavate; fifth ventral segment truncate and slightly depressed in the middle behind in

the male.

Length 2-27 millim. (¢ 9.)

Hab. Panama, Volcan de Chiriqui 3000 feet (Champion).

Numerous examples. Less elongate and much smaller than A. guinguemaculatus and

A. concinnus ; the anterior portion of the thorax less convex; the elytra more shining

and with fine but very distinct series of setiferous punctures (in addition to, and very

distinct from, the dense minute punctuation). The peculiar pattern of the elytra will

be best understood from our figure: the testaceous mark on each elytron beyond the

middle is narrower and much more oblique than in A. coucinnus, and the apical patch

is smaller and has a branch extending upwards on either side of the suture.

* There are many places of this name in Central and South America; the insect is probably not Chilian.

230 HETEROMERA.

10. Anthicus foveiventris. (Tab. X. fig. 9, ¢.)

Elongate ; the head reddish-testaceous, shining; the prothorax fusco-ferruginous, dull; the elytra rather

shining, piceous, with a transverse testaceous fascia a little below the base and another beyond the middle,

the suture very narrowly and the space beyond the second fascia brownish; the upper surface clothed

with fine appressed pubescence, with scattered intermixed erect bristly hairs. Head broader than long,

a little dilated at the sides behind, with a shallow occipital groove, very finely, shallowly, and closely

punctured ; the eyes black, coarsely granulated, large, rather prominent ; antennee moderately long, very

stout, submoniliform, joints 9 and 10 transverse, 1-7 reddish-testaceous, 8—11 piceous-brown, the tip of

the eleventh ferruginous; prothorax longer than broad, a little narrower than the head, rounded at the

sides before and strongly constricted behind the middle, the anterior portion transversely convex, the

posterior portion short and feebly dilated at the base externally, the base without distinct margin, the

flanks moderately excavate, the surface finely rugulose, dull; elytra rather long, a little narrowed in

front, with a deep transverse post-basal depression (occapied by the first fascia) and moderately convex

beyond this, the humeri somewhat obtuse, the surface very finely and closely punctured; legs very stout

(the femora especially), testaceous, the tibie in great part and the hind femora (except at the base) piceous,

the four hinder tarsi fusco-testaceous ; fifth ventral segment deeply foveate in the middle behind and

emarginate on either side at the apex, the median portion angsty produced, and all the tibie slightly

sinuate on their inner side, in the male.

Length 3 millim. (<¢.)

Hab. Guatemata, El Reposo (Champion).

One male example, found in the Pacific coast-region.

This and the following species have the antenne very stout and submoniliform, and

the elytra piceous, with two testaceous, almost straight, transverse fascie. They are not

closely allied to any others known as yet from Central or South America. In A. fovei-

ventris the legs are very stout, the femora especially, and the transverse post-basal

depression of the elytra is deep; the male has all the tibie a little sinuous on their

inner edge and somewhat dilated, and the last ventral segment very deeply foveate in

the middle.

11. Anthicus crassicornis.

Very closely resembling A. foveiventris, and differing only as follows:—The antenne shorter, a little more

slender towards the base, and with joints 7-10 transverse; the elytra proportionately narrower, less

densely pubescent, and not so closely punctured; the legs not so stout, the anterior and intermediate

femora also infuscate in their outer half; all the tibie slightly sinuate within, the hind pair distinctly

curved (not straight) without, and the fifth ventral segment truncate at the apex and unimpressed, in

the male.

Length 3 millim. (<¢.)

Hab. Guatemaa, San Gerénimo (Champion).

One male example. This insect so exactly resembles the preceding at first sight as

to appear indistinguishable from it; the form of the fifth ventral segment in the

male is, however, totally different from that of the same sex of A. foveiventris, and this

peculiarity is accompanied by the other above-mentioned less important points of

distinction. Owing to the more strongly transverse penultimate joints and the rather

less stout basal ones, the antenne appear to be more widened outwardly than in

A. foveiventris ; the hind tibie in the male are distinctly curved outwardly in A. crassi-

corms, the outer edge being almost straight in A. foveiventris.

12. Anthicus dilatipes. (Tab. X. fig. 10, 3.)

Elongate, shining, finely and sparsely pubescent, the head and prothorax reddish-testaceous, the elytra piceous.

‘Head strongly transverse, a little rounded at the sides behind, sparsely and very minutely punctured ;

the eyes large and prominent, black; antenne moderately long, testaceous ; prothorax longer than broad,

narrower than the head, the sides very much constricted behind the middle and thence to the base parallel,

the anterior portion transversely convex, the posterior portion cylindrical, the flanks deeply excavated,

the base feebly margined, the surface minutely and somewhat closely punctured ; elytra long, widest at

the middle, subparallel in front, with a very shallow transverse post-basal depression, sparsely and very

finely punctured, the punctuation becoming very minute towards the apex; legs fusco-testaceous, the

base of the femora and the tarsi testaceous, the femora moderately clavate; fifth ventral segment truncate,

and the hind tibize on the inner side gradually dilated to beyond the middle and then abruptly narrowed

and concave to the apex, in the male.

Length 23 millim. (¢.)

Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith).

One male example. This species approaches A. obscurus and the allied forms, but

differs from these in the strongly dilated posterior tibiz in the male. The elytra have

a very shallow post-basal depression, and the punctuation is fine and sparse.

13. Anthicus obscurus.

Hab. Norra America, United States +, Coney I.2.—Merxico, Northern Sonora

(Morrison).

This insect is, I believe, widely distributed in the United States. Three examples

received from Sonora agree with one forwarded by Dr. Horn and with the types in

the La Ferté collection. A. obscurus has the thorax and elytra more minutely punc-

tured than in A. occidentalis ; the elytra have a shallow post-basal depression, and are

minutely and thickly punctured and finely pubescent ; the head is minutely punctured,

almost smooth, strongly transverse ; the antenne are piceous, with the basal two or

three joints lighter. The head and thorax are sometimes reddish-brown, The posterior

tibie are slightly sinuous within, and the fifth ventral segment is truncate, in the male.

14. Anthicus occidentalis.

Elongate, shining, varying in colour from fusco-testaceous to piceous, the head and prothorax often reddish,

finely pubescent. Head short, transverse, rounded at the sides behind, minutely and somewhat thickly

punctured (in some examples more obsoletely so), the eyes prominent and moderately large ; antennse

long, testaceous, the three or four apical joints usually infuscate; prothorax longer than broad, narrower

than the head, the sides very strongly constricted behind the middle and thence to the base almost straight,

the anterior portion transversely convex, the posterior portion cylindrical, the flanks with a deep exca-

vation, the base margined, the surface finely and closely punctured ; elytra long, subparallel in their basal

half, shallowly transversely depressed below the base and somewhat flattened beyond this, the humeri

obtuse but rather prominent, the surface finely and somewhat closely punctured, the punctuation becoming

coarser towards the base; legs testaceous or fusco-testaceous, the outer half of the femora sometimes

darker, the femora clavate; fifth ventral segment truncate, and the posterior tibie slightly swollen and

sinuous within, in the male.

Length 24-22 millim. (¢ @.)

232 HETEROMERA.

Var. The elytra more finely and more uniformly punctured, the punctuation becoming very little coarser

towards the base.

Hab. GUATEMALA, near the city, San J oaquin (Champion).

The typical form was found in plenty by Herr Hoge at Acapulco on the Pacific

coast, and the variety in equal numbers by myself in the vicinity of the city of

Guatemala. A single specimen from San Joaquin is somewhat intermediate, and some

of the Acapulco examples are more finely punctured than others, so that I am quite

unable to distinguish more than one species. A. occidentalis is almost intermediate

between A. obscurus, La Ferté, and A. nitidulus, Lec. ; but in the sculpture of the

head and the shallow post-basal depression of the elytra it approaches more nearly to

A. obscurus. The antenne are testaceous, with the three or four apical joints, at most,

infuscate ; the elytra are less minutely and more sparsely punctured than in J. obscurus,

finely and uniformly pubescent, and rather depressed. The head is much smoother

than in A. nitidulus, and more transverse than in A. asphaltinus. The elytral punc-

tuation is finer and more diffuse, and the pubescence is sparser than in A. punctipennis.

The head and thorax have a brassy lustre in some of the Guatemalan specimens.

A. occidentalis averages smaller in size than A. nitidulus.

15. Anthicus aterrimus.

Elongate, black, very shining, finely and very sparsely pubescent, the pubescence on the basal portion of the

elytra denser and ashy in colour. Head strongly transverse, a little rounded at the sides behind, sparsely

and minutely punctured, the eyes large and prominent; antenne long, piceous, the four or five basal

joints reddish-testaceous; prothorax much longer than broad, very convex, the sides very strongly con-

stricted behind the middle and thence to the base almost straight, the anterior portion transversely convex,

the posterior portion cylindrical, the flanks very deeply excavated, the base distinctly margined, the

surface sparsely and minutely punctured ; elytra long, widest at the middle, subparallel in front, with a

rather deep post-basal depression and moderately convex beyond this, the humeri somewhat prominent,

the surface sparsely and very minutely punctured, the punctuation closer and more distinct at the base,

the pubescence transversely arranged in the depressed part; legs piceous, the femora testaceous at the

base, the latter clavate; fifth ventral segment truncate, and the hind tibie rather stout and strongly

sinuous within, in the male.

Length 24 millim. (<¢.)

Hab. Guatemaa, El Tumbador 2500 feet (Champion).

Two examples, both males, from the Pacific slope of Guatemala. This species

resembles the Colombian A. ebeninus, La Ferté, in its very shining black colour and

comparatively smooth surface ; it differs from that insect (the types of which I have

examined) in the longer thorax and the much deeper post-basal depression of the

elytra; the hind tibie are stouter and more sinuous within, and the fifth ventral

segment is unimpressed, in the male. The short, transverse head and the sparse and

minute punctuation of the upper surface separate it from A. asphaltinus ; the sparser

punctuation of the thorax and elytra, the deeper post-basal depression of the latter,

and the more shining surface distinguish it from A. obscurus, A. occidentalis, &c.

pubescence ; the upper surface (when denuded of pubescence) moderately shining. Head large, trans-

verse, rounded at the sides behind, not very convex, densely and finely punctured; the eyes large and

prominent; last joint of the maxillary palpi very broad; antenne long, thickening a little outwardly,

piceous or piceous-brown, the three basal joints testaceous; prothorax considerably longer than broad,

. narrower than the head, the sides rounded before and very strongly constricted behind the middle, and

thence to the base almost straight, the anterior portion transversely convex, the posterior portion cylin-

drical and very little dilated laterally at the base, the flanks with a very deep groove, the base finely

margined, the surface very densely and finely punctured ; elytra long, subparallel to about the middle,

broadly transversely depressed below the base and moderately convex beyond this, the humeri obtuse but

prominent, the entire surface very closely and finely punctured, the punctuation on the basal portion very

dense, the ashy pubescence transversely arranged in the depressed part and obliquely or longitudinally so

before and behind this, the pubescence beyond the middle much darker and very much sparser and finer ;

legs varying in colour from piceous to piceous-brown, the femora more or less testaceous at the base and

sometimes entirely fusco-testaceous ; the femora distinctly clavate ; fifth ventral segment truncate, and

the hind tibie slightly sinuate on the inner side, in the male.

pion), Zapote, Duefias, San Gerénimo (Champion); Nicaragua (Sallé), Chontales

(Janson).—VENEZUELA, Caracas (coll. Oberthiir).

A widely-distributed and rather common species on the plateau of Central America,

and extending southwards to’Venezuela. A. punctipennis has quite the facies and

colour of A. bactrianus and A. tumidicollis, but differs from both in the thorax not

being gibbous behind; the dense punctuation of the elytra, more particularly of the

basal portion, and the dense appressed whitish pubescence of the latter distinguish

the species from the North-American A. obscurus, La Ferté, and A. nitidulus, Lec.

(typical examples of which are before me), and from the other allied forms here

described. The anterior portion of the elytra is duller than the rest of the surface,

the punctuation being very dense on this part; the basal portion is transversely convex

and without distinct swelling near the suture. The head in some specimens is pitchy-

red, but in a long series the elytra show no tendency, as in some of the allied forms,

to have the basal portion reddish.

17. Anthicus asphaltinus. (Tab. X. fig. 12.)

Of the same form and colour as A. punctipennis and differing as follows:—The head longer and narrower, the

sides behind the eyes obliquely converging and less rounded, the surface more finely and less densely

punctured (in some examples almost smooth); the antenne piceous-brown, with three or more of the

pasal joints testaceous, sometimes almost entirely testaceous ; prothorax a little more dilated laterally at

the base, rather narrower than the head, not quite so densely punctured; elytra less parallel, widest at

the middle and somewhat ovate, the post-basal depression deeper, the punctuation fine and sparse, and

closer and coarser on the basal portion; the entire upper surface more shining, and very sparsely and

finely pubescent, the pubescence not transversely arranged on the depressed part ; the male characters as

in A, punctrpennis.

Var. The head, the prothorax, and the shoulders of the elytra more or less reddish-brown.

Hab. Muxico, Guanajuato (Sallé, Dugeés).

Numerous examples of the typical form, three of the variety. The more ovate head,

the more shining surface, and the much more diffuse punctuation and the sparse

pubescence of the elytra distinguish this insect at once from A. punctipennis. The

much less transverse head separates it from A. obscurus, La Ferté, A. occidentalis, and

other allied forms. The punctuation of the head is fine and rather dense, but in some

examples is almost obsolete. In a long series of specimens the elytra vary a little in

the intensity of the punctuation and in the depth of the post-basal depression, this

latter being scarcely visible in one male example.

18. Anthicus bactrianus. (Tab. X. figg. 13, ¢; 134, profile.)

Elongate, black or brownish-black, the head and prothorax in one example pitchy-red, shining ; the head and

prothorax sparsely, the elytra more thickly, clothed with fine decumbent pubescence, the pubescence on

the elytra ashy in tint at the base. Head broader than long, moderately convex, rounded at the sides

behind, thickly and not very finely punctured, the eyes large and prominent; the last joint of the maxil-

lary palpi very broad; antenne long, very gradually and only a little thickened outwardly, piceous or

piceous-brown, the basal joints lighter; prothorax much longer than broad, narrower than the head, the

sides rounded before and very strongly constricted behind the middle and thence to the base almost

straight, the anterior portion convex, the posterior portion rather long and strongly and abruptly gibbous,

the flanks with a very deep excavation extending upwards, the base finely margined, the disc thickly

and finely punctured, the sides smooth; elytra long, subparallel to about the middle, broadly transversely

depressed below the base and moderately convex beyond this, the basal portion finely and rather densely,

the rest of the surface more shallowly and sparsely, punctured, the humeri obtuse but somewhat promi-

nent; legs varying in colour from piceous to fusco-testaceous, the tarsi not lighter than the femora or

tibiz, the femora distinctly clavate, the spurs of the hind tibie long ; fifth ventral segment truncate, and

the hind tibie slightly sinuate on the inner side, in the male.

Length 23-22 millim. (¢ 9.)

Hab. Mexico, Cerro de Plumas (Hége), Guanajuato (Sallé); GuaTEMALA, Quiche

Mountains, Capetillo, Santa Rosa in Vera Paz (Champion).

Nine examples. This insect resembles A. obscurus, La Ferté, and A. nitidulus, Lec.,

from both of which it differs in having the posterior portion of the thorax strongly

gibbous and raised very much above the level of the convex anterior portion, the space

between the two very deeply excavate at the sides. No species possessing this peculiarity

was known to La Ferté. The last joint of the maxillary palpi is largely developed,

and the spurs of the hind tibiz are very distinct. A. bactrianus appears to be confined

to Mexico and the highlands of Guatemala ; the following species comes very near it.

19. ‘Anthicus tumidicollis.

Closely allied to A. bactrianus. The head much more sparsely and less distinctly punctured, and more shining ;

the posterior portion of the prothorax less strongly gibbous and not so abruptly raised in front (viewed

laterally, the disc appears to be very little depressed between the anterior and posterior portions), the

excavation in the flanks not so deep; the rest, including the male characters, as in A. bactrianus.

Length 23 millim. (¢.) : .

Hab. Panama, Pefia Blanca 2000 feet (Champion).

Two male examples. In the form of the thorax this insect is somewhat intermediate

between A. bactrianus and A, obscurus and its allies. The posterior portion of the

thorax is raised above the level of the anterior portion, but is more rounded and less

conically elevated than in A. bactrianus.

Hab. Nortu America, Delaware 3, New Jersey °, Texas, California 1, San Diego ?.—

Mexico (coll. Oberthiir), Manzanillo (Hége), Guanajuato (Sallé, Dugés), Mexico city

(Hoge, H. H. Smith).

We have received four examples of this species from within the limits of our fauna,

two of the typical form and two of the var. 8; others from Mexico are also contained

in the collection of M. Réné Oberthiir. These agree well with La Ferté’s types. The

insect appears to be widely distributed in the United States. A. californicus is an

ally of the European A. humilis, Germ., and equally variable in colour ; the head is

about as long as broad ; the thorax is strongly constricted behind, obsoletely bituber-

culate in the middle at the base, and very distinctly punctured, the punctuation

_ becoming denser towards the base; the elytra are long, without post-basal depression,

and closely and rather coarsely punctured ; the upper surface is shining and sparsely

pubescent. The locality “California” requires confirmation.

21. Anthicus invalidus. (Tab. X. fig. 14.)

Anthicus invalidus, La Ferté, Monogr. Anthic. p. 136°.

Two specimens of this species are contained in the La Ferté collection: one, the

type, from Colombia, is in a very mutilated condition and without antenne ; the other,

from Panama, labelled .A. aldicornis, Motsch., is not mentioned by the author in his

monograph. We give a fresh description from the additional examples captured by

myself in Guatemala; these differ from La Ferté’s definition of the species in having a

distinct post-basal depression to the elytra.

Elongate, reddish-testaceous or ferruginous, very shining; the elytra with the base rather broadly and a

common transverse fascia just beyond the middle piceous or brownish, sometimes with only a large spot

at the shoulders and another at the sides at the middle brownish; the upper surface clothed with long

erect, scattered hairs, those on the elytra serially arranged. Head nearly as long as broad, rounded at

the sides behind, foveate on each side in front and with a few widely scattered fine, deep punctures ; the

eyes black, coarsely granulated, large and prominent ; antenns long and slender, the apical three or four

and the two basal joints testaceous or flavo-testaceous, the others black or piceous, the apical joint acumi-

nate and rather long; prothorax longer than broad, narrower than the head, rounded at the sides before

and strongly constricted behind the middle, the anterior portion transversely convex, the posterior portion

a little dilated at the base externally, the base distinctly margined, the flanks deeply excavated, the sur-

face with rather coarse, deep, very widely scattered punctures; elytra broadly truncate at the base, mode-

rately long, the sides subparallel in front, a little dilated at the middle, and obliquely converging behind,

moderately convex, and with a shallow quite distinct transverse post-basal depression, the humeri obtuse

but distinct, the basal fourth with rather coarse scattered punctures, the rest of the surface almost smooth ;

legs pale testaceous, the tibie usually infuscate in their basal half; fifth ventral segment deeply semi-

circularly emarginate in the male.

Hab. GuateMALA, Rio Naranjo, San Joaquin, Lanquin, Chiacam ( Champion); _ PANAMA

(coll. La Ferté).—Co.tomstia * (coll. Oberthiir).

A. invalidus has much the facies of A. varicornis and A. striato-punctatus, from which

it may be at once distinguished by the simply rounded (not denticulate) sides of the

thorax; the antenne are differently coloured; the elytra are more obliquely narrowed

behind and the punctuation is more irregularly arranged and scarcely extends beyond

the basal depression.

This insect frequents the sandy banks of rivers and occurs on both the Atlantic and

Pacific slopes of Guatemala.

22. Anthicus concolor. (Tab. X. fig. 15.)

Moderately elongate, pale castaneous, very shining ; the upper surface clothed with long, erect, scattered hairs,

those on the elytra serially arranged. Head about as long as broad, rounded at the sides behind, with a

few very widely scattered minute punctures; the eyes black, comparatively large, coarsely granulated,

prominent ; antenne entirely testaceous, slender, the apical joint acuminate and comparatively long ;

prothorax longer than broad, much narrower than the head, rounded at the sides before and strongly

constricted behind the middle, the anterior portion transversely convex, the posterior portion dilated at

the base externally, the base margined, the flanks deeply excavated, the surface punctured like that of

the head; elytra broad, comparatively short, gradually widening to about the middle and there more

than three times the width of the prothorax, slightly compressed behind the shoulders, and obliquely con-

verging behind, broadly truncate at the base, the disc flattened anteriorly and moderately convex behind,

without post-basal depression, the humeri prominent, the surface with very minute widely-scattered

punctures ; legs long and slender, entirely testaceous.

Length 2 millim. (9.)

Hab. GuateMata (Sallé), Rio Naranjo (Champion).

Four female examples of this insect were captured by myself on the sandy banks of

the Rio Naranjo, in the Pacific coast-region of Guatemala, and there is a very immature

example of it in the Sallé collection. The unicolorous, very shining, almost smooth

surface, slender limbs, and comparatively broad, short elytra, the latter merely

flattened on the basal portion of the disc, and with the humeri very prominent, chiefly

distinguish A. concolor.

23. Anthicus festivus.

Moderately elongate, pale castaneous, very shining ; the elytra with an indistinct brownish median fascia; the

upper surface clothed with long, erect, scattered hairs, those on the elytra serially arranged. Head as

long as broad, rounded at the sides behind, with a few very widely scattered minute punctures; the eyes

black, large, moderately prominent; antennz submoniliform, short, about reaching the base of the pro-

thorax, the apical three joints distinctly wider than the preceding, the tenth transverse, joints 1-3 and

10 and 11 testaceous, the others piceous-brown; prothorax longer than broad, narrower than the head,

rounded at the sides before and strongly constricted behind the middle, the anterior portion transversely

convex, the posterior portion subcylindrical, the base distinctly margined, the flanks deeply excavated, the

surface punctured like that of the head; elytra moderately long, a little narrowed in front, somewhat

obliquely narrowing behind, transversely flattened anteriorly and rather convex beyond, without post-

basal depression, the humeri obtuse, the surface with a few widely scattered minute punctures, almost

smooth ; legs testaceous, the tibie slightly infuscate.

Length 12 millim.

Hab. Mexico, Cordova, (Sal/é).

One example, apparently a male. Narrower and smaller than A. concolor; the

elytra more ovate and with less prominent shoulders; the antenne differently coloured,

much shorter and more moniliform, and with the apical three joints distinctly widened,

the tenth being transverse (instead of longer than broad) and the eleventh shorter.

Very much smaller than A. invalidus, La Ferté, the elytra not coarsely punctured

towards the base, the antenne much shorter, &c.

24, Anthicus isthmicus. (Tab. X. fig. 16.)

Moderately elongate, reddish-testaceous or ferruginous, very shining ; the elytra with a broad yellowish trans-

verse median fascia, the fascia preceded and followed and sometimes interrupted at the suture by an

indeterminate piceous-brown cloud; the upper surface clothed with fine, scattered, long, erect yellowish

hairs, those on the elytra serially arranged. Head about as long as broad, rounded at the sides behind,

with a few widely scattered fine punctures, the eyes black and rather prominent ; antenne moderately

long, very little thickened outwardly, piceous, the basal joint (and sometimes the second also) testaceous,

the apical two or three joints flavous, the eleventh acuminate; prothorax longer than broad, narrower

than the head, rounded at the sides before and strongly constricted behind the middle, the anterior portion

transversely convex, the posterior portion subcylindrical, slightly dilated at the base externally, the flanks

deeply excavated, the base finely margined, the surface punctured like that of the head; elytra short,

ovate, regularly convex, without trace of a post-basal depression, the sides compressed just below the

shoulders, the base subtruncate, the apex broadly rounded, the humeri obtuse but distinct, the basal third

with very distinct serially arranged punctures, the rest of the surface almost smooth; legs testaceous, the

basal two-thirds of the tibize piceous or infuscate, the femora slender; fifth ventral segment truncate at

the apex in the male.

Length 137-2 millim. (¢ 9.)

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

Not uncommon in the warmer parts of Central America, more particularly on the

Atlantic slope. Allied to A. equinoctialis, La Ferté, from which it differs in having

the elytra closely and confusedly punctured from the base to the apex (the punctures

becoming a little coarser towards the base). The head and thorax are duller and more

finely rugulose; the head is more angularly extended at the sides behind; the thorax

has the lateral tooth sharper and longer, this tooth usually preceded and followed by a

shorter one, each tooth bearing a long projecting bristly hair; and the elytra have a

transverse subangular black median fascia and a transverse anteapical one, these fascie

connected along the suture.

Central-American specimens, of which about forty are before me, have the elytra a

little more coarsely punctured than the La Ferté types, and the thoracic teeth less -

distinct. La Ferté’s outline figure of the thorax is incorrect and misleading. One

example, from Mexico, labelled A. nigrosignatus, Deyr., in M. Réné Oberthiir’s collec-

tion, has the elytra still more coarsely punctured; but with the extensive series before

me Iam unable to distinguish more than one species. Specimens of what is apparently

an extreme form, from the Amazons, are separated in the La Ferté collection and

labelled A. longicornis; these have the thoracic teeth almost obsolete. In one of the

typical examples of La Ferté the thoracic teeth are much longer than in the others.

The eight examples before me from Central America only differ from La Ferté’s

description of this species in having the head and thorax lighter in colour—pitchy-red

instead of black—and the basal one or two joints of the antennz fusco-testaceous or

testaceous ; they agree perfectly with the types. Allied to A. spinicollis, but differing

from it by the very coarse sculpture of the head and thorax and the very prominent

eyes. The antenne (the basal one or two joints excepted) are black, with the apical

joints flavous; the head is very coarsely and rugosely punctured, and has a smooth

longitudinal space along the middle, the basal portion being also smooth and shining ;

the thorax is shining, angularly dilated at the sides before the middle (and also furnished

with one or two short teeth in front of this), and very coarsely punctured, the punctures

confluent on the anterior portion; the elytra are rather coarsely striate-punctate to a

little beyond the middle and thence to the apex almost smooth, and have a common

Central-American specimens agree well with La Ferté’s types and description. In

this insect the head and thorax are rugulose and opaque, and ferruginous in colour ;

the elytra are testaceous or reddish-testaceous, shining, rather coarsely striate-punctate

to a little beyond the middle, the punctures thence to the apex abruptly becoming very

much finer; the eyes are large and prominent ; the thorax has a short tooth at the sides

before the middle ; the transverse post-basal depression of the elytra is moderately deep ;

the antenne are pale ferruginous; the legs are entirely testaceous; the posterior tibie

in both sexes are slightly curved and somewhat dilated. A. rugosus, La Ferté, from

Brazil, is a very closely allied form.

28. Anthicus varicornis.

Elongate, pitchy-red, shining ; the elytra testaceous or flavo-testaceous, with a common black or piceous median

fascia (not reaching the lateral margin) and a brownish apical patch, these markings usually connected

along the suture and showing a tendency to enclose a large ante-apical spot of the ground-colour on each

elytron, the extreme base and scutellar region sometimes brownish (in one example this brown marking

extends along the suture to the median fascia); the entire upper surface sparsely clothed with long, erect,

bristly hairs, Head rounded at the sides and very convex behind, with only a few very widely scattered

punctures at the sides and in front, the eyes not very prominent; the palpi piceous; antenne black, the

basal one or two joints testaceous, the apical one flavous; prothorax much longer than broad, transversely

convex anteriorly, the sides obsoletely denticulate and somewhat angularly dilated before the middle, strongly

constricted behind, and feebly dilated at the extreme base, the latter margined, the flanks with a deep

excavation, the surface sparsely and rather finely punctured; elytra coarsely striate-punctate to a little

beyond the middle and thence to the apex almost smooth, the transverse post-basal depression shallow but

distinct ; legs flavo-testaceous or testaceous, the base of the tibie usually black or infuscate ; fifth ventral

segment deeply triangularly depressed in the middle behind and the apex truncate in the male.

Length 2-23 millim. (¢ 9.)

Hab. GuateMaa, San Juan and Senahu in Vera Paz (Champion); Nicaracvua (Sallé),

Seven examples. Closely allied to A. striato-punctatus, La Ferté, from which it may

readily be distinguished by the very much smoother thorax and the much less prominent

eyes; the elytra are similarly marked and similarly sculptured, and the antenne also

have the apical joint flavous. In some specimens the head and thorax are reddish-

testaceous.

Anthicus (Ischyropalpus) quadriplagiatus, La Ferté, Monogr. Authic. p. 148°.

Hab. Panama, San Lorenzo in Chiriqui (Champion).—CoLomBIA 1.

Three female specimens of this species were captured by myself in the “ tierra

caliente” of Chiriqui; they agree perfectly with the type contained in the La Ferté

collection. A. sericans (Er.), La Ferté, from Peru and Brazil, is a closely allied form.

The subgenus Jschyropalpus was proposed by La Ferté to include these and some other

species from Tropical South America, all of comparatively large size ; they have the

thorax greatly rounded and dilated at the sides anteriorly, abruptly and obliquely

narrowed from about the middle, slightly dilated at the base, the flanks concave, and

the lateral margins rather prominent. In A. guadriplagiatus the entire upper surface

is very densely and finely punctured and almost opaque; the head and thorax are

ferruginous ; the elytra reddish- or flavo-testaceous, with an ill-defined triangular scutellar’

patch, a common transverse fascia a little beyond the middle, and the suture narrowly,

piceous or brownish. The elytra are long, parallel, and rather depressed. The form

of the head is well shown by La Ferté (op. cit. t. 27. fig. 23). The thorax is as wide

as, or even wider than, the head.

30. Anthicus exiguus. (Tab. X. fig. 20.)

Short, of a uniform testaceous colour, slightly shining, thickly clothed with fine, silky, appressed, yellowish

pubescence. Head large and broad, somewhat angularly extended on either side behind, coarsely and

closely punctured, with a smooth central line, the occiput distinctly impressed, the eyes black and mode-

rately prominent ; antenne short, about reaching the base of the prothorax, entirely testaceous ; prothorax

broader than long, as wide as or wider than the head (in some examples more strongly transverse than in

others), moderately convex, broadest in front and obliquely narrowing thence to the base, the surface

finely and densely punctured, the base very obsoletely margined ; elytra short, moderately convex, rounded

at the sides, the humeri obtuse, the base slightly emarginate, the surface densely but less finely punctured

than that of the prothorax; legs entirely testaceous; fifth ventral segment truncate and unimpressed in

the male. ,

Length 13-13 millim. (¢ 2.)

Hab. GUATEMALA, Champerico (Champion).

Found in plenty by myself on the Pacific coast. This minute species is allied to the

European A. bimaculatus, Illig., and to the North-American A. maritimus, Lec., and

A. ictericus, La Ferté ; it differs from A. ictericus, which it resembles in its small size,

in having the head very much more coarsely and less closely punctured and also more

rounded at the sides behind (the head in A. ictericus being broadly truncate at the base).

The type of A. ictericus is not contained in the La Ferté collection, but Dr. Horn has

kindly forwarded an example of the species for examination. This insect, as noted by

Leconte (Proc. Acad. Phil. vi. p. 102), is from the Atlantic coast.

31. Anthicus dilaticollis.

Moderately elongate, of a uniform testaceous or fusco-testaceous colour, the suture of the elytra often infuscate

for a short distance before the apex, thickly clothed with fine decumbent pubescence. Head large and

broad, somewhat angularly extended on either side behind (the sides parallel immediately behind the eyes),

closely and rather coarsely punctured, with a smooth central line, the occiput slightly impressed, the eyes

black and moderately prominent; antenne short, about reaching the base of the prothorax, testaceous ;

prothorax moderately convex, about as broad as (or rather broader than) long, as wide as the head, widest

in front and obliquely narrowing thence to the base, the surface densely and finely punctured, the base

obsoletely margined ; elytra comparatively short, a little rounded at the sides, the humeri obtuse but

moderately prominent, the base slightly emarginate, the surface densely but less finely punctured than

that of the prothorax ; legs entirely testaceous ; fifth ventral segment truncate in the male.

Hab. Mexico, Ventanas (Forrer, in coll. Oberthiir), Guanajuato, Soledad (Sal/é),

Thirteen examples. Larger and more elongate than A. exiguus, the elytra relatively

longer and less ovate; also closely allied to the N.-American A. ictericus, La Ferté, but

differing from that species in its more coarsely punctured head. From A. spretus, Lec.,

a specimen of which from Arizona has been communicated by Dr. Horn, it may be

known by the thorax being broader in front and more transverse, the head less coarsely

punctured, and the elytra less elongate. A. lugubris, La Ferté, from California, also

resembles A. dilaticollis, but differs from it in its black colour and smaller eyes.

32. Anthicus basimacula. (Tab. X. fig. 21.)

Moderately elongate, black, the shoulders of the elytra broadly testaceous, slightly shining, thickly clothed with

fine, ashy, appressed pubescence. Head large and broad, somewhat angularly extended on either side

behind, densely and finely punctured, with a smooth central line, the occiput distinctly impressed ; the

eyes moderately prominent, rather small; the palpi testaceous ; antennx short, barely reaching the base

of the prothorax, entirely testaceous ; prothorax moderately convex, about as broad as long, rather wider

than the head, widest in front and obliquely narrowing thence to the base, the surface densely and finely

punctured, the disc with an obsolete median groove behind the middle ending in a distinct impression

before the base, the base feebly margined ; elytra moderately long, a little rounded at the sides, subparallel

in front, the humeri rounded but rather prominent, the surface very closely punctured, the punctuation

coarser than that of the prothorax ; legs testaceous, the femora slightly darker. .

Length 24 millim.

Hab. Mexico, Aguas Calientes city ( Hoge).

One example only, apparently a female. In the elytral markings this insect

resembles the European A. fenestratus, Schmidt; it is perhaps nearest allied to

A. dilaticollis.

33, Anthicus pauxillus. (Tab. X. fig. 22.)

Moderately elongate; the head and prothorax varying in colour from ferruginous to piceous ; the elytra testa-

ceous, with a broad transverse median fascia (not quite reaching the suture) and an apical patch piceous

or black, these markings usually connected along the lateral margin and near the suture (thus enclosing a

spot of the ground-colour) ; the upper surface shining and finely pubescent. Head very large, strongly

transverse, broadly truncated behind, very closely and finely punctured, with a smooth central line, the

occiput not impressed, the eyes large ; antenne testaceous or fusco-testaceous, slender, extending a little

beyond the base of the prothorax, the penultimate joints transverse ; prothorax a little narrower than the

head, about as broad as long, widest in front and obliquely narrowing thence to the base, the base feebly

margined, the surface very closely and finely punctured; elytra convex, comparatively short, slightly

rounded at the sides, the humeri rounded, the surface densely and finely punctured, the punctuation coarser

than that of the prothorax ; legs testaceous or flavo-testaceous.

Length 13 millim. (¢ 9.)

Hab. Guatemata, Zapote, Capetillo, Balheu (Champion).

Five examples. This insect is very like A. minusculus, but differs in the head being

more finely punctured, the thorax broader in front and more obliquely narrowing

behind, and the elytra less densely punctured. The elytra are entirely testaceous at the

base, and the median fascia is usually connected near the suture and at the sides with

the apical one, so as to enclose a spot of the ground-colour (the markings thus resem-

punctured and the thorax less dilated at the sides in front. Examples of a closely

allied undescribed form from San Domingo (Sallé) are contained in La Ferté’s collection,

and there labelled A. dominicanus, La Ferté. :

Central-American specimens of this variable species belong to the var. 6 of La Ferté.

I have examined his types of A. vicinus and A. letus, and fail to find any difference of

importance between them ; the latter chiefly differing from the light-coloured form of

A. vicinus in having the elytra black at the base. Texan examples of the typical form

and of the var. 6 of A. vicinus have been communicated by M. Sallé and Dr. Horn for

comparison. ‘The species is common in Mexico and Guatemala. A. vicinus is allied

to A. floralis, but is very much narrower and smaller than that insect, and the head is

without occipital impression. Central-American specimens are of a bright reddish-

testaceous colour, the elytra each with a large spot on the disc about the middle

(sometimes in the form of a broad transverse fascia almost united to the opposite one

at the suture) and the apex black; sometimes the elytra have a triangular scutellar

patch, or the base narrowly, infuscate. In the United States entirely dark forms occur.

The upper surface is very shining and almost glabrous; the head and thorax bear fine

widely scattered punctures ; the elytra are long, rather depressed, coarsely and some-

what thickly punctured ; the legs and antenne are testaceous.

Anthicus infernus, La Ferté, Monogr. Anthic. p. 159°.

Hab. Mexico! (coll. Oberthiir), Mexico city (Hage), Guanajuato (Sallé, ex Dugés).

Our specimens from Guanajuato and Mexico city agree perfectly with La Ferté’s

type. They are black and very shining ; the head is comparatively long, and subangu-

larly dilated at the sides behind; the eyes are very small; the thorax is obliquely

narrowed from a little before the middle, margined at the base; the elytra are long,

parallel, and depressed, coarsely punctured, with prominent humeri and the suture a

little raised ; the upper surface is almost bare.

glabrous.

A single example captured on our northern boundary by Herr Hoge during his

second expedition agrees very well with Leconte’s diagnosis *:—‘ Elongatus, testaceus,

longiusculo subcampanulato, elytris grosse punctatis, fascia obscura pone medium

ornatis. Long. °11.”

39. Anthicus macrocephalus. (Tab. X. fig. 24.)

Elongate, of a uniform fusco-testaceous colour, shining, thickly clothed with long, rather coarse, decumbent

whitish pubescence. Head convex, comparatively elongate, narrow, rounded at the sides behind, thickly

and finely punctured, a longitudinal space down the middle smooth, the occiput unimpressed, the eyes

black, large, and somewhat prominent ; antenne moderately long, rather slender, entirely testaceous ; pro-

thorax convex, rather longer than broad, very little narrower than the head, the sides gradually and

obliquely converging from the middle and slightly dilated at the extreme base, the base shallowly grooved

within, the surface densely and finely punctured; elytra elongate-oval, about twice the width of the

prothorax, feebly depressed on either side of the suture towards the apex, without post-basal depression,

the humeri rounded but rather prominent, the surface densely and somewhat coarsely punctured, the punctu-

ation becoming very much finer beyond the middle ; legs entirely testaceous ; fifth ventral segment simply

truncate in the male.

Length 24 millim. (<¢.)

Hab. Mexico, Teapa in Tabasco (H, H. Smith), Yucatan (coll. Oberthiir).

Two examples. Amongst the species described by La Ferté, 4A. macrocephalus is

nearest allied to A. pusillus, from which it differs by the much narrower and longer

head, the much longer and entirely testaceous antenne, and the longer thorax. The

comparatively narrow elongate head distinguishes the species from all the other Central-

American representatives of this section of the genus.

40. Anthicus lutescens.

Moderately elongate, of a uniform testaceous or fusco-testaceous colour, rather shining, somewhat thickly

clothed with fine, decumbent, yellowish pubescence. Head transverse, convex, rounded at the sides

behind, subtruncate at the base, closely and finely punctured, and with a smooth central line, the occiput

not or very faintly impressed; the eyes black, moderately large, not very prominent; antennz testaceous,

extending a little beyond the base of the prothorax, slender, thickening outwardly ; prothorax convex, as

long as broad, a little narrower than the head, broadest in front, the sides gradually and obliquely con-

verging posteriorly and a little dilated at the extreme base, the base finely margined towards the sides,

the surface densely and finely punctured; elytra moderately long, a little rounded at the sides, the humeri

rounded, the base feebly emarginate and slightly swollen on either side of the scutellum, the surface very

closely punctured, the punctuation coarser than that of the prothorax ; legs flavo-testaceous ; fifth ventral

segment truncate and unimpressed in the male.

Length 23-23 millim. (¢ 9.)

Hab. Muxico, Teapa (H. H. Smith, Hoge) ; GUATEMALA, Paso Antonio (Champion).

Four examples, two from the Atlantic and two from the Pacific slope. . Less elongate

than A. macrocephalus; the head very much shorter; the elytra broader, more rounded

at the sides, and more finely punctured; the pubescence shorter and much finer. Very

near A. pusillus, La Ferté, from New Orleans (the type of which I have examined), but

differing from it in having the head narrower, the antenne longer, and the elytra not

so coarsely punctured, the punctuation of the head also coarser and less close; also

closely allied to a Texan insect communicated by M. Sallé (under the name A. pusillus,

but not agreeing with La Ferté’s type), but with less truncate head and shorter and finer

pubescence. A. spretus, Lec. (=A. facilis, Casey), much resembles A. lutescens, but

has a flatter, more truncate, and much more coarsely punctured head, and the sides of

the thorax not dilated at the base.

A female example of an Anthicus received from Western Mexico merely differs from

La Ferté’s type of A. cervinus and from others of the same species from the United States

communicated by M. Sallé and Dr. Horn in having the elytra a little broader and less

parallel : in the absence of further material it is not advisable to separate it from that

insect. A. cervinus is stated by Leconte 4 to be avery variable species; it has the upper

surface densely and somewhat coarsely punctured and rather thickly pubescent; the

head with a smooth central line and without occipital groove. The specimens before

us are ferruginous or reddish-testaceous in colour; the elytra with a broad transverse

fascia beyond the middle (not reaching the suture and widening outwardly), and the

apex piceous or black, these markings connected near the suture and enclosing a spot

of the ground-colour on each elytron.

A second example, from Villa Lerdo in Durango (£dége), is perhaps an extreme form

of the same species.

Anthicus quadrilunatus, La Ferté, Monogr. Anthic. p. 201, t. 29. figg. 1 a-1d (nec. Lec.) ’.

Hab. Nort America, ? California!.—Mexico (coll. Oberthiir), Mexico city (Hoge,

H. H. Smith).

We have received seven examples of this variable species from the neighbourhood of

the city of Mexico, and there are three others from Mexico in the collection of M. Réné

Oberthiir: those in which the elytral spots are well defined agree precisely with La

Ferté’s type. ‘The insect varies according to the predominance of the ferruginous or of

the pitchy-black colour ; in one specimen the anterior spots of the elytra are entirely

obsolete and the posterior ones much reduced in size, in others the spots are greatly

extended: and more or less confluent; in some examples the spots are of a bright red

colour. i

A. quadrilunatus is an elongate rather convex species allied to the European A. anthe-

rinus, Linn. ; the entire upper surface is coarsely and closely punctured, and clothed with

rather long, coarse pubescence; the punctuation of the elytra is much coarser than

that of the head and thorax; the legs vary in colour, but the femora are always

darker towards the apex. It is more convex than the North-American A. haldemani,

Lec. (a specimen of which I have before me), and also differs in the head being unim-

pressed behind, &c.

Hab. Nortu America, New Mexico1, Texas (coll. Sallé), Arizona (Horn).—Guvats-

MALA, Rio Naranjo (Champion).

A single example, captured by myself in the Pacific coast-region of Guatemala, is

referable to this species; it agrees well with a specimen from Texas, communicated

by M. Sallé, and with one from Arizona forwarded to us by Dr. Horn under the name

of A. quadrilunatus. Smaller and less convex than A. guadrilunatus, La Ferté; the

head with a very distinct occipital impression and a smooth central line; the pubes-

cence of the upper surface shorter and finer and the punctuation not nearly so coarse ;

the legs and antenne testaceous ; the elytra much flatter on the disc.

Leconte’s doubts as to his correct identification of A. guadrilunatus, La Ferté, prove

to be well grounded, the New-Mexican specimen described by him under that name !

belonging to a very different species.

44, Anthicus currax.

Elongate, moderately shining ; the head and prothorax testaceous or flavo-testaceous ; the elytra piceous, each

with two large flavous spots, one below the base and another near the apex (the anterior one transverse

and extending to the lateral margin and sometimes to the suture); the upper surface finely and somewhat

thickly pubescent. Head moderately large, strongly transverse, feebly convex, subangularly dilated at

the sides behind, broadly truncate at the base, and with a distinct occipital impression, very sparsely and

finely punctured, a longitudinal space down the middle smooth, the eyes large; antenne entirely testaceous ;

prothorax about as long as broad, moderately convex, a little narrower than the head, the sides obliquely

converging from before the middle and parallel at the extreme base, the base very shallowly grooved on

either side within, the disc distinctly canaliculate, the surface very finely and densely punctured ; elytra

long and subparallel, flattened on the disc, with an exceedingly shallow broad post-basal depression (occu-

pied by the anterior flavous spot), the humeri rounded, the surface closely and finely punctured (the

punctures coarser than those on the prothorax) ; legs slender, pale testaceous ; the fifth ventral segment

simply truncate in the male.

Length 3} millim. (¢ 9.)

Hab. Mexico (coll. Oberthiir), Soledad (Sal/é).

Four examples. This species is allied to A. tetrops, but it has the head and thorax

more convex, narrower, shining, and flavo-testaceous in colour ; the head is much

smaller ; the elytral spots are larger, the anterior one extending to the lateral margin.

More elongate than A. lecontei, the upper surface much more finely punctured.

The only known locality for A. currasz is Soledad, on the Atlantic slope.

45. Anthicus tetrops. (Tab. X. fig. 27.)

Elongate, depressed ; the head and prothorax ferruginous or flavo-ferruginous, opaque; the elytra piceous, each

with a rather large transverse or slightly oblique testaceous spot on the dise before the middle and a

smaller one on the disc towards the apex, slightly shining ; the upper surface somewhat thickly clothed

with fine, silky, appressed pubescence and with a few widely scattered short erect hairs. Head very large

and broad, strongly transverse, dilated at the sides behind, broadly truncate at the base, and with a very

distinct occipital impression, somewhat flattened in front, sparsely and very finely (but quite distinctly)

punctured, a longitudinal space down the middle smooth, the eyes black, large, and rather prominent ;

antenne rather slender, joints 7-10 subtriangular, testaceous, the outer joints slightly infuscate ; prothorax

about as broad as long, a little narrower than the head, slightly flattened on the disc, the sides obliquely

converging from before the middle and a little dilated at the extreme base, the base shallowly grooved on

either side within, the dise obsoletely canaliculate, the surface very finely and densely punctured ; elytra

long and subparallel, slightly narrowed anteriorly, a little flattened on the disc, the humeri rounded, the

surface closely and finely punctured (the punctures coarser than those on the head and prothorax), without

post-basal depression ; legs slender, testaceous ; the fifth ventral segment simply truncate at the apex in

the male.

Length 23-33 millim. (¢ 9.)

Hab. Guatemaua, Champerico (Champion).

Ten examples, found on the Pacific coast at Champerico. Allied to A, lecontei,

but with the head and thorax ferruginous, much less convex, more finely punctured, and

opaque, the head more strongly transverse, the elytra more finely punctured, &c. The

elytral spots vary a little in size, but they do not reach the suture. The head is sub-

triangular and comparatively very large.

46, Anthicus minusculus.

Moderately elongate; the head varying in colour from flavo-testaceous to piceous, the prothorax from testa-

ceous to piceous with the dise obscurely ferruginous ; the elytra testaceous or ferruginous, with the base

(in one specimen indistinctly), a very broad transverse median fascia (not reaching the suture), and the

apex black (these markings connected along the lateral margin in one specimen); the upper surface

shining, finely pubescent. Head moderately large, truncate behind, closely and somewhat coarsely punc-

tured, with a smooth central line, the occiput not or very feebly impressed, the eyes large; antenne

testaceous or fusco-testaceous, short, about reaching the base of the prothorax, slender, the penultimate

joints transverse ; prothorax convex, about as long as broad, narrower than the head, narrowing behind,

the base obsoletely margined, the surface densely and finely punctured ; elytra convex, comparatively

short, feebly rounded at the sides, the humeri rounded, the surface densely and finely punctured, the

punctuation a little coarser than that of the prothorax ; legs testaceous or fusco-testaceous.

Length 1 millim. (¢ 9.)

Hab. GuatTEMALA, Panajachel, San Gerénimo (Champion).

Three examples. This species is closely allied to the N.-American A. nanus and

A. bellulus, Lec. Compared with an example of the former, from Arizona, communicated

by Dr. Horn, A. minusculus is smaller, more convex, and a little less elongate; the head

is smaller and not so broad, and the elytra are black at the base and apex. A. bellulus,

from San Diego, California, appears to have a more densely and more finely punctured

head and a finer frontal line. All four species are of very small size.

Hab. Nortu America, ¢ California (Piccolimini) 1—Mexico (coll. Oberthiir), Ciudad in

Durango (Hége), Guanajuato (Sallé, Dugés).

This very distinct Anthicus has been captured in some numbers by M. E. Dugés at

Guanajuato. Our examples agree precisely with La Ferté’s type. The locality

“California” is probably erroneous. The insect was unknown to Leconte. An elon-

gate, parallel, rather convex species, brownish-black in colour, and subopaque; the

entire upper surface very densely and finely (the elytra a little more coarsely) punctured,

and thickly clothed with extremely short, appressed, scale-like, greyish pubescence; the

antenne and legs fusco-ferruginous or ferruginous. A. sguamosus has much the facies

of a Monotoma.

pion).

Our numerous Central-American specimens of this species are smaller and less elon-

gate than the La Ferté types or than any I have seen from the United States; but in a

long series of examples there is considerable variation in size. The elytra are also not

quite so coarsely punctured. Mexican and Guatemalan examples are smaller and

shorter than the others; Chiriqui specimens are more like those from Florida &c. The

ANTHICUS. 249

species of this section have a peculiar facies, owing to the short head and thorax and

elongate comparatively broad elytra. The head is sparsely and minutely punctured and

has a smooth central line; the occiput is not impressed. The antenne are short, very

slender at the base, and thickened outwardly, the penultimate joints as broad as long ;

the basal joints are testaceous, the apical joints infuscate. The thorax is scarcely so

long as broad, very densely and minutely punctured, distinctly margined at the base.

The elytra are rather convex, closely and coarsely punctured, the punctuation becoming

very much finer towards the apex. The fifth ventral segment is truncate and unim-

pressed in the male. Examples occur of a light reddish-brown colour.

49. Anthicus teapensis, (Tab. X. fig. 28.)

Moderately elongate, pitchy- or brownish-black, the prothorax sometimes ferruginous at the base and apex, the

head and prothorax dull, the elytra moderately shining, the upper surface thickly clothed with fine decum-

bent pubescence. Head strongly transverse, truncate behind, densely and minutely punctured and with

a fine smooth central line, the occiput distinctly impressed, the eyes very large and moderately prominent ;

antenne very short, about reaching the base of the prothorax, the penultimate joints transverse, testa-

ceous, the three or four apical joints infuscate ; prothorax not quite so long as broad, much narrower than

the head, moderately convex, narrowed at the sides behind and dilated at the base, the base very distinctly

margined, the surface densely and minutely punctured; elytra rather convex, twice as wide as the pro-

thorax, moderately elongate, subparallel in the male, a little more ovate in the female, truncate at the

base, the humeri rounded, the base a little swollen on either side of the scutellum, the surface closely and

coarsely punctured, the punctuation becoming very much finer beyond the middle; legs entirely testa-

ceous; fifth ventral segment deeply foveate in the middle and truncate at the apex in the male.

Length 23-23 millim. (¢ 9.)

Hab. Muxico, Frontera and San Juan Bautista in Tabasco (Hége), Teapa in Tabasco

(Hoge, H. H. Smith).

This insect is not uncommon in the Mexican State of Tabasco, whence we have

received numerous examples. A. teapensis is closely allied to A. fulvipes, La Ferté (an

insect also occurring in Tabasco), but differs from that species in the head being densely

and more minutely punctured, the occiput distinctly impressed, and the antenne shorter,

the latter having the penultimate joints transverse; the fifth ventral segment is also

deeply foveate in the male. In A. fulvipes the head is much smoother than the thorax ;

in A. teapensis the head and thorax are almost equally densely punctured.

50. Anthicus federatus.

Moderately elongate, the head and prothorax ferruginous, piceous-brown, or piceous, the elytra piceous-brown,

with the suture very narrowly darker; the head and elytra moderately shining, the prothorax dull; the

upper surface clothed with rather long, fine, decumbent pubescence. Head transverse, convex, truncate

behind, sparsely and minutely punctured, with a fine smooth central line, the occiput unimpressed, the

eyes very large; antenne extending beyond the base of the prothorax, moderately slender at the base,

‘thickening outwardly, the penultimate joints subtriangular, testaceous, the outer four or five joints usually

infuscate ; prothorax as long as broad, narrower than the head, moderately convex, narrowed at the sides

behind and slightly dilated at the base, the base distinctly margined, the surface very densely and minutely

punctured ; elytra rather convex, twice as wide as the prothorax, moderately elongate, subparallel towards

the base, the humeri rounded, the base a little swollen on either side of the suture and truncate, the

surface closely and coarsely punctured, the punctuation becoming very much finer beyond the middle; legs

entirely testaceous; fifth ventral segment shallowly transversely depressed in the middle and truncate at

the apex in the male.

Length 23-24 millim. (¢ 9.)

Hab. Guatemata, Yzabal (Sallé), Rio Naranjo (Champion).

Eleven examples, ten from the Pacific and one from the Atlantic slope. Extremely

close to A. fulvipes, La Ferté, and only separable by the longer and stouter antenne

and by the male having the fifth ventral segment transversely concave in the middle.

It also approaches A. lutescens, but differs from that species in having the thorax more

densely and more minutely punctured (and consequently more opaque), the elytra more

truncate at the base and more uniformly punctured (the punctuation much coarser on

the basal half), and the pubescence longer and coarser.

Fam. MORDELLIDZE.

Group ANASPIDES.

The three known North-American genera are all represented within our region, and

anew genus is required for some of the Central-American forms. The group is not

nearly so numerous in species as the Mordellides in the warmer regions of the earth,

and seventeen only are here recorded from Central America; of these ten belong to

Pentaria, one to Diclidia, one to Anaspis, and five to a new genus.

All the Central-American members of the group were obtained at a considerable

elevation above the sea.

DICLIDIA.

Diclidia, Leconte, Proc. Acad. Phil. xiv. p. 48 (1862); J. B. Smith, Trans. Am. Ent. Soc. x. p. 75.

The single species from Guatemala referred to this genus agrees accurately with

Leconte’s definition. The compressed and much elevated mesosternum (this being very

sharply carinate between the middle coxe in front) and the bilobed penultimate joint

of the anterior and middle tarsi are its chief characters. The male of the Guatemalan

insect, like that of the North-American one, possesses very peculiar appendages to the

abdomen. ‘The sixth ventral segment is well exposed in the male, but it is covered by

the fifth and not visible in the female.

1. Diclidia undata. (Tab. XI. fige. 1, 9; la, terminal ventral segments of

the abdomen, ¢ .)

Moderately elongate, densely and very finely pubescent, finely transversely strigose above ; testaceous or flavo-

_testaceous ; the prothorax irregularly mottled with piceous (between which ill-defined spots of the

ground-colour are visible); the elytra with an irregular oblong patch on the middle of the disc at the

base, a common strongly angulated rather broad median fascia, from which a branch extends upwards on

either side of the suture, a broad anteapical fascia (extending forwards at the suture and sometimes on the

middle of the disc also, and usually with an oblique branch extending downwards), and the suture. at the

base narrowly, piceous. Eyes coarsely granulated, black ; antenne testaceous, the intermediate joints a

little darker in one example, very long and slender, thickening a little outwardly, distinctly shorter in the

female than in the male, joints 3 and 4 equal in length, each about as long as 1 and 2 together, 5 much

shorter than 4, 5-7 decreasing in length, 8-10 wider than 7, subtriangular, equal, 11 ovate, much longer

than 10; prothorax about one half broader than long, the sides rounded and rapidly converging from a

little before the base, the hind angles subrectangular ; beneath in great part infuscate ; legs testaceous or

fusco-testaceous, very long and slender, the penultimate joint of the front and middle tarsi as long as the

preceding joint, and strongly bilobed.

¢. Abdomen with two long flattened appendages proceeding from the tip (between which the central sheath

of the cedeagus is extruded), the appendages concave and clothed with long fine hairs within, widened out-

wardly, and very obliquely truncate at the apex; the sixth ventral segment exposed, fully half the length

of the fifth, and finely carinate down the middle behind ; the fifth ventral segment unemarginate.

Length 34-4 millim. (¢ 2.)

Hab. Gexremata, Cerro Zunil 4000 feet, Panajachel 5000 feet (Champion).

One male and four female examples. This insect has much the facies of an Hallo-

menus. It differs from the Texan D. letula, Lec., a specimen of which has been kindly

communicated by Dr. Horn, in the strongly angulated and more numerous dark markings

of the elytra (these being equally variable in extent) and in the infuscate thorax; and

also in the unemarginate fifth ventral segment in the male. The abdominal appendages

of the male are only visible when the genital organs are extruded.

PENTARIA.

Anthobates, Leconte, in Agass. Lake Superior, p. 231.

Of the six described species of Pentaria four are from the United States. The genus

proves to be well represented in Central America, whence ten species are now recorded ;

it evidently replaces Anaspis in the warmer regions of the New World. The species

here referred to it agree in having the fourth joint of the four anterior tarsi bilobed

and nearly equal to the third in length and breadth, the posterior tibie long and

slender, and the prothorax and elytra transversely strigose. Most authors state that the

sixth ventral segment is visible in this genus: in some of our species it is just visible

beyond the fifth, in others (in the males especially) it is well exposed, but in several

cases (in both sexes) it is completely covered by the fifth. The ventral segments are

apparently similar in form in the two sexes of Pentaria, except in P. trisiqnata, in

which the fifth is triangularly emarginate and does not cover the sixth. In P. canescens

the tibies show distinct traces of oblique grooves on their outer face. ‘The apical joint

of the labial palpi appears to be more slender in this genus than in Anaspis, and less

abruptly truncate at the apex.

1. Pentaria canescens.

Moderately elongate, black, the labrum only a little lighter in colour ; the upper surface opaque, thickly clothed

with fine sericeous ashy pubescence, the prothorax and elytra densely transversely strigose. Head

moderately large; antenne rather short, thickening outwardly, joints 9 and 10 transverse, black, the

One male and three female examples. The former has been quite recently sent me

by Mr. Flohr, who states that the insect was beaten from the branches of an oak. The

species is not closely allied to any of the North-American Pentariew. In fresh examples

the pubescence is almost white in certain lights. The sixth ventral segment is not

visible in the male,

PENTARIA. 253

2. Pentaria flavipes.

Moderately elongate, pitchy-black, the elytra usually fuscous or brownish from a little below the base to the

apex, the labrum and mouth-parts testaceous or fusco-testaceous; the upper surface opaque, finely

pubescent, the prothorax and elytra very densely transversely strigose. Head comparatively broad ;

antenne short (not nearly reaching the base of the prothorax when the head is extended), thickening

outwardly, joints 8-10 strongly transverse, 1-6 testaceous, 7-11 piceous or black ; palpi testaceous, the

apical joint sometimes darker at the tip; prothorax about one half broader than long, very feebly bisinuate

at the base, rounded at the sides, the hind angles subrectangular; beneath piceous; legs slender, testaceous,

the anterior tarsi very feebly dilated in the male; fifth ventral segment similar in both sexes.

Length 23-25 millim. (¢ Q.)

Hab. Mexico, Guanajuato (Sal/é).

Six examples. Smaller and a little less elongate than P. canescens; the antenne

shorter and with the basal six joints testaceous; the elytra not so black ; the legs more

slender and entirely testaceous. The male apparently has the head broader than in the

female, and the anterior tarsi feebly dilated (less so than in P. canescens). P. fuscula,

Lec., from Texas and New Mexico, seems to be an allied species.

3. Pentaria brunneipennis.

Moderately elongate, rather narrow; the head and prothorax piceous ; the elytra reddish-testaceous to about

one-third from the base, thence to the apex brown, the apical third a little paler in colour, the suture very

narrowly infuscate ; the upper surface slightly shining, finely pubescent, the prothorax and elytra exceed-

ingly finely transversely strigose. Head small; antenne rather short (not quite reaching the base of the

prothorax when the head is extended), thickening outwardly, joints 9 and 10 transverse, 1-6 flavo-

testaceous, 7-11 piceous; palpi flavo-testaceous ; prothorax about one-third broader than long, bisinuate

at the base, moderately rounded at the sides, the hind angles rectangular; beneath piceous; legs rather

stout, testaceous, all the femora piceous, but paler towards the apex, the tarsi slightly infuscate; the hind

tibize about as long as the three basal joints of the posterior tarsi united, with traces of oblique grooves on

their outer face.

Length 24 millim. (9.)

Hab. Muxico, Chilpancingo (H. H. Smith).

One female example. Smaller, narrower, and more shining than P. canescens; the

thorax relatively longer; the elytra brown, this colour becoming more dilute and redder

in tint towards the base; the transverse strigation of the upper surface less dense.

4. Pentaria brevicornis.

Moderately elongate, rather narrow, black, the mouth-parts testaceous ; the upper surface dull, finely pubescent,

the prothorax and elytra very finely transversely strigose. Head small; antenne very short (reaching very

little beyond the middle of the prothorax when the head is extended), thickening outwardly, joints 8-10

transverse, 1-5 testaceous, 6-11 piceous; palpi testaceous; prothorax about one third broader than long,

the sides somewhat obliquely converging anteriorly and very little rounded, the hind angles rectangular,

the base a little produced in the middle behind; beneath piceous; legs slender, piceo-testaceous or

infuscate, the tibie a little lighter.

Length 23-23 millim.

slender than P. canescens, the antenne much shorter and more clavate, the head

smaller and narrower. ‘The darker legs, smaller head, less transverse thorax (the sides

of which are less rounded, and the base is more produced in the middle behind), and

shorter antenne distinguish it from P. flavipes. The base of the thorax is somewhat

strongly bisinuate, and the tarsi are slender. This species also would appear to be

allied to P. fuscula, Lec., the description of which (copied by Smith) is insufficient

for identification *. |

5. Pentaria bicincta.

Very elongate, testaceous ; the elytra with a brownish or piceous fascia just beyond the middle, and another a

little before the apex (the former extending upwards at the suture and at the sides, the latter not reaching

the lateral margins, and in one example not reaching the suture), and the base on either side of the suture

slightly infuscate; the upper surface opaque, finely pubescent, the prothorax and elytra finely transversely

strigose. Head moderately large, the eyes black; antenne testaceous, rather slender, elongate (extending

beyond the base of the prothorax when the head is extended), thickening outwardly, joints 3 and 4 com-

paratively long, subequal, 9 and 10 about as broad as long; palpi pale testaceous; prothorax about

one third broader than long, bisinuate at the base, feebly rounded at the sides, the hind angles sharply

rectangular; beneath fusco-ferruginous ; legs entirely testaceous.

Length 3-4 millim. (¢ 9.)

Hab. Mexico, Pinos Altos in Chihuahua (Buchan-Hepburn).

Two examples. The largest of the Central-American species of the genus. It differs

from the following, P. trisignata, in its more elongate shape (the elytra being relatively

much longer) and less distinct markings, those at the base of the elytra being scarcely

visible, and the others much less extended (in one example the median fascia is almost

obliterated); the legs and antenne are paler; and the fifth ventral segment in the male

is unemarginate. ‘The longer and more slender antenne and the different pattern of

the elytra distinguish it from P. trifasciata. The sixth ventral segment is not visible.

6. Pentaria trisignata. (Tab. XI. fig. 2.)

Moderately elongate, rather broad; the head and prothorax ferruginous; the elytra testaceous, with a broad

median fascia, which extends forwards along the suture and also at the sides, and is connected at the

suture with a broad basal patch, and an anteapical fascia (in some examples not reaching the lateral

margins, in others extending to the apex), black; the upper surface opaque, very densely and finely

pubescent, the prothorax and elytra finely transversely strigose. Head moderately large, the eyes black ;

antenne testaceous or fusco-testaceous, comparatively long (reaching beyond the base of the prothorax

when the head is extended), rather slender, thickening outwardly, joints 3 and 4 elongate, subeqnal, 5-10

increasing in width but decreasing in length, 9 and 10 about as broad as long; palpi testaceous ; prothorax

about one third broader than long, feebly bisinuate at the base, a little rounded at the sides, the hind angles

rectangular; beneath ferruginous or flavo-ferruginous, the venter, and sometimes the metasternum also,

infuscate or piceous ; legs testaceous or fusco-testaceous, moderately slender; fifth ventral segment trian-

gularly emarginate at the apex and the sixth well exposed in the male, the anterior tarsi slender in

this sex.

Length 2$-33 millim. (3 @.)

Hab. Muxico, Guanajuato (Sallé).

* «“ Body entirely fuscous or piceous, legs and base of antenne paler.”

- PENTARIA, 259

Six examples. Duller and more densely pubescent than the North-American

P. trifasciata, Melsh. (a specimen of which has been communicated by Dr. Horn),

the antennz longer, the black markings of the elytra more extended—the median

fascia broadly connected along the suture with the basal one, but the latter does not

(as in P. trifasciata) reach the humeri. If black is taken as the ground-colour,

the elytra may be described as having an oblique stripe extending from the shoulders

downwards (curving upwards near the suture in some specimens), a narrow fascia

beyond the middle, and sometimes the extreme apex, brownish-yellow.

7. Pentaria quadriguttata. (Tab. XI. figg. 3; 4, var.)

Moderately elongate ; the head testaceous or reddish-testaceous; the prothorax in great part piceous, the base

and apex of the same colour as the head (the light colour often forming a large spot on either side of the

middle at the base); the elytra piceous or fuscous, each with a broad flavo-testaceous fascia before and

another beyond the middle (the former sometimes connected with the opposite one at the suture, and

extending along the side to the base, the latter not reaching the suture), the suture a little lighter in

colour; the upper surface subopaque, finely pubescent, the prothorax and elytra finely transversely

strigose. Head moderately large, the eyes black; antennew short (scarcely reaching the base of the

prothorax when the head is extended), thickening outwardly, joints 9 and 10 subtransverse, 1-4

testaceous, 5-11 piceous or brown; palpi testaceous; prothorax about one third broader than long

feebly bisinuate at the base, slightly rounded at the sides, the hind angles rectangular; beneath piceo-

testaceous, the metasternum and venter darker; legs testaceous, moderately slender; sixth ventral

segment visible.

Length 23-3} millim. (¢ @.)

Hab. Guatemata, Capetillo, Guatemala city, San Gerénimo (Champion); Panama,

Volcan de Chiriqui (Champion).

Var. The piceous colour on the prothorax reduced to a well-defined transverse median band ; the testaceous

elytral fasciee much larger and longer, but not reaching the suture, the dark basal mark in the form of a

large triangular scutellar patch, this being lighter in colour than the median and apical bands. (@.)

Hab. Mexico, Cuernavaca (H. H. Smith).

Eight examples of the typical form and one of the variety. The much shorter

antenne, more shining surface, partly infuscate thorax, different elytral markings, &c.,

distinguish this species at a glance from P. trisignata and P. trifasciata. The insect

varies in the amount of the dark and light colour, but two very distinct transverse

or oblong spots are always visible on each elytron, and the thorax is more or less

infuscate across the middle; the pubescence partakes of the colour of the surface from

which it arises. P. guadriguttata has much the facies of a banded Addera.

8. Pentaria unifasciata. (Tab. XI. fig. 5.)

Comparatively short ; testaceous, the elytra each with a rather broad black transverse median band which does

not reach either the suture or the lateral margin; the upper surface slightly shining, finely pubescent, the

prothorax and elytra very finely transversely strigose. Head moderately large, the eyes black; antenne

testaceous, slightly darker towards the apex, short (not nearly reaching the base of the prothorax when

the head is extended), thickening outwardly, joints 9 and 10 transverse; prothorax about one half broader

than long, feebly bisinuate at the base, a little rounded at, the sides, the hind angles rectangular; beneath

in great part piceous ; legs slender, entirely testaceous.

Length 23° millim.

Hab. Guatemata, Capetillo (Champion).

One example. Less elongate than P. guadriguttata, the antenne a little shorter, the

thorax and elytra testaceous, the latter with a median black fascia divided at the suture.

The elytra are, relatively, a good deal shorter than in the above-mentioned species.

P. nubila, Lec., from California, is evidently an ally of P. unifasciata; but, according

to J. B. Smith’s figure (Trans. Am. Ent. Soc. x. t. 1. fig. 11), it is a more elongate insect,

and has the elytral fascia uninterrupted at the suture.

9. Pentaria decolor.

Moderately elongate; testaceous, the elytra sometimes slightly infuscate along the middle of the dise and having

the suture and sides paler, the prothorax more ferruginous in colour in some examples; the upper surfaee

opaque, thickly clothed with fine silky pubescence, the prothorax and elytra finely transversely strigose.

Head moderately large, the eyes black; antenne rather short, thickening outwardly, joints 9 and 10

subtransverse, testaceous, the apical joints sometimes infuscate; palpi testaceous; prothorax about one

half broader than long, feebly bisinuate at the base, moderately rounded at the sides, the hind angles

rectangular; beneath varying in colour from testaceous to fuscous; legs entirely testaceous; sixth ventral

segment partly exposed in the male, and sometimes visible in the female.

Length 2-3 millim. (¢ 2.)

This species appears to be common in Mexico, whence we have received a large

number of specimens. Those forwarded by Morrison from Sonora were labelled

Anaspis rufa; the present insect, however, differs from Anaspis in having a well-

developed bilobed penultimate joint to the anterior and middle tarsi. The entirely

pale colour and the less elongate shape distinguish it at once from P. quadriguttata,

and the larger size, longer antenne, and immaculate elytra separate it from P. unifas-

ciata; P. decolor is, however, not very closely allied to any of the other species here

described, though P. angustata comes near it.

10. Pentaria angustata.

Moderately elongate, narrow, testaceous; the upper surface opaque, finely pubescent, the prothorax and elytra

very finely transversely strigose. Head moderately large, the eyes black ; antennz rather short, thickening

outwardly, joints 9 and 10 transverse, testaceous, the apical four joints a little darker; prothorax about

one half broader than long, narrowing from the base, the sides very little rounded, the hind angles rectan-

gular; beneath and the legs testaceous.

Length 12 millim. (¢.)

Hab. Nicaragua, Chontales (Janson).

One male example. Narrower and smaller than P. decolor, the antenne shorter, the.

thorax less rounded at the sides. The transversely strigose elytra and the longer and

PENTARIA.—NAUCLES. 257

more slender tibie (the hind pair longer than the two basal joints of the posterior tarsi

united) distinguish it from all the species of the following genus, to some of which it

bears a close resemblance.

NAUCLES.

Mandibles toothed within just before the apex; last joint of the maxillary palpi stout, oblong-ovate, very

obliquely truncate at the apex, the apex acuminate ; second joint of the labial palpi very stout, ovate, the

apical joint quite slender and acuminate; lobes of the maxille narrow, rather long; mentum strongly trans-

verse, narrowing a little in front ; antenne short, somewhat clavate, the penultimate joints transverse ; eyes

coarsely granulated; fourth joint of the anterior and middle tarsi bilobed, as broad as, but shorter than,

the third; all the tibia short and compressed, considerably dilated towards the apex, the posterior pair

not longer than, or scarcely us long as, the first two joints of the posterior tarsi united ; upper surface

very densely and minutely punctured, the punctures on the prothorax and on the extreme base of the

elytra only forming faint transverse strige; ventral segments similar in both sexes, the sixth covered by

the fifth; epipleuree much narrowed behind the posterior cox, and extending to about the apex of the

third ventral segment; body oblong, subovate; the rest as in Pentaria.

The above generic name is proposed to include several minute closely allied species

from Central America. Most of the characters are very similar to those of Pentaria;

but the short and conspicuously dilated tibie and the form of the labial palpi, the

apical joint of which is very slender and acuminate, and the second joint very stout,

forbid association with that genus. The four anterior tibie are broader at the apex

and more compressed than in Anaspis, the hind pair similarly shaped. The short

posterior tibie and the larger penultimate joint of the four anterior tarsi separate

Naucles from Cyrtanaspis, Emery. The general shape is shorter and more ovate than

in Pentaria. In the sculpture of the upper surface the genus differs from all the allied

forms, there being no trace of transverse strigze on the greater part of the elytra, the

thorax and the extreme base of the elytra only, at most, being very faintly transversely

strigose. The ventral segments, as in Pentaria, are without external appendages in the

male. ‘The characters of the mouth-parts are taken from J. tibialis. The species are

very feebly differentiated, and in the absence of external male characters difficult to

distinguish.

1. Naucles tibialis. (Tab. XI. figg. 6; 6, labium; 66, maxillary palpus.)

Oblong-ovate, entirely testaceous; the upper surface very densely and minutely punctured, the punctures on

the prothorax and on the extreme base of the elytra only showing a tendency to form faint transverse

strige, thickly clothed with very fine silky pubescence. Head moderately large, the eyes black; antennse

short (not nearly reaching the base of the prothorax when the head is extended), joints 1 and 2 oblong,

stout, subequal, 3-6 more slender, 3 shorter than 2, 4 much shorter than 3, 4-6 subequal, 7-11 much

wider than 6, 7 about as broad as long, 8-10 strongly transverse, 11 ovate, longer than 10, testaceous,

the basal joints a little lighter in colour; prothorax about one half broader than long, feebly bisinuate at

the base, the sides moderately rounded, the hind angles subrectangular ; all the tibiee becoming broadly

dilated towards the apex, the hind pair not longer than the two basal joints of the posterior tarsi united.

2. Naucles basalis.

Oblong ovate, rather narrow; the head ferruginous; the prothorax piceous or fusco-ferruginous; the elytra

piceous, the shoulders and the sides towards the apex indeterminately testaceous or reddish; the upper

surface very densely and minutely punctured, the punctures forming faint transverse strige on the pro-

thorax and on the extreme base of the elytra only, very finely and thickly pubescent. Head moderately

large, the eyes black; antenne as in N. tibialis, but with the joints 7-10 infuscate; prothorax about one

half broader than long, moderately rounded at the sides ; beneath piceous; legs testaceous.

Length 13-1} millim.

Hab. Guatemaua, Capetillo, San Gerénimo (Champion).

Two examples, one of which is a female. Closely allied to WV. tibialis; the elytra

piceous with a spot at the shoulders and the sides towards the apex reddish or testa-

ceous; the intermediate joints of the antenne infuscate.

3. Naucles quercus.

Oblong ovate, rather convex, entirely reddish-testaceous ; the upper surface very densely and minutely punc-

tured, the punctures forming very fine transverse strige on the prothorax and on the extreme base of the

elytra, very finely and thickly pubescent. Head, prothorax, and antenne much as in N. tibialis, the elytra

more distinctly punctured; beneath ferruginous ; legs testaceous.

Length 13 millim.

Hab. Mexico, near the city (Flohr).

Three examples, beaten from oaks in the vicinity of the city of Mexico, and recently

forwarded to me by Mr. Flohr. Very near WN. ¢idiatis, from which it can only be distin-

guished by its more convex and rather broader shape, larger size, and more distinctly

punctured elytra. A mutilated example from Guanajuato (Sallé) perhaps belongs to

the same species.

4. Naucles affinis.

Oblong ovate, rather narrow, still narrower in the male, brownish-testaceous ; the upper surface thickly clothed

with fine silky pubescence, very densely and minutely punctured, the punctures forming very fine trans-

verse strigze on the prothorax and on the extreme base of the elytra. Antenne brownish, with the basal

joints paler; prothorax narrowing from the base, about one half broader than long, the sides feebly

rounded ; beneath ferruginous ; legs testaceous.

Length 13-12 millim. (¢ 9.)

Hab. Panama, Pefia Blanca (Champion).

This familiar genus is almost confined to the temperate regions of the northern

hemisphere. One of the North-American forms extends southwards to just within our

limits. Anaspis has been divided into several subgenera by Emery ; the single species

here recorded belongs to his section “ Anaspis sensu stricto.”

Hab. Norra America, California! 2, Colorado ?.—Mexico, Northern Sonora (Morrison).

Specimens received from the late Mr. Morrison are apparently referable to this

species. Neither Leconte nor J. B. Smith mention the sex of the examples described

by them: in the male of the Sonoran insect the fifth ventral segment is cleft down the

middle from the apex nearly to the base, and from the apex of the third segment two

long slender appendages are extruded, these being very narrowly separated and resting

parallel to each other along the centre of the segments 3-5, and extending to the apex,

the space between them smooth but not depressed. The insect is closely allied to

A. frontalis (Linn.) and other Kuropean species.

Group MORDELLIDES.

This group is very largely represented in Central America, the majority of the

species, as in other regions, belonging to Mordella or Mordellistena. One remarkable

new genus is added, this being without the characteristic anal style, and thus differing

from all other known members of the group. Most of the Central-American repre-

sentatives are described as new, two only having hitherto been recorded from within

our limits. In the descriptions of the new species the length-measurements are taken

from the front of the thorax to the end of the elytra and from the front of the thorax

to the tip of the pygidium when the insect is extended; and the breadth-measurements

from the widest part of the thorax.

COTHURUS.

Last joint of the maxillary palpi exceedingly broad, large, and securiform, its apical side concave and nearly twice

the length of the outer side, the latter not much shorter than the inner side; eyes finely granulated ;

scutellum trapezoidal, twice as broad as long, a little produced in the middle behind; the last dorsal

segment obtuse at the apex, not prolonged into a style; metasternum sharply transversely keeled in front

immediately behind the widely separated middle coxa, its anterior edge vertical, the keel extending outwards

as far as the coxe; penultimate joint of the four anterior tarsi dilated, excavate; hind tibie without

oblique ridges on their outer face (the short subapical one excepted); body very broad, short; the form

of the claws and other characters as in Mordella.

This new genus is proposed for a single species from Mexico. It is one of the most

interesting forms of Mordellide yet discovered, differing as it does from all other

members of the group Mordellides in the shape of the last dorsal segment and in that

of the metasternum.

1. Cothurus iridescens. (Tab. XI. figg. 7; 7a, maxillary palpus.)

Very broad, short, metallic blue, the prothorax in front and the head with brassy reflections; the elytra densely

and coarsely, the prothorax more finely, punctured; the elytra, scutellum, disc of the prothorax, and the

head in the middle sparsely blackish-brown-pubescent, the sides of the head and of the prothorax more

densely clothed with whitish pubescence, the head golden-pubescent in front. Head exceedingly broad,

short; the eyes very large, extending to the occiput, and thickly pubescent; the oral organs (the tip of

the mandibles excepted) flavo-testaceous; antenne flavo-testaceous, the outer four or five joints infuscate,

slender, rather short, joints 3-5 thin, equal in length, 5 a little wider than 4, 6-10 serrate, 8-10 about

as broad as long; prothorax strongly transverse, deeply sinuate on either side of the broad median basal

lobe, the latter subtruncate ; elytra convex, a little narrower than the prothorax, short, only about one

and a half times as long as broad, broadly and separately rounded at the apex; the last four dorsal and

ventral segments fulvous, thickly clothed with fulvous-golden-pubescence, the rest of the under surface

obscure violaceous and yellowish-cinereous-pubescent; anterior and intermediate legs in great part and

the hind tibial spurs testaceous; the hind femora, tibiw, and tarsi black, the base of each tarsal joint

sometimes paler; the inner spur of the hind tibise very elongate, three times as long as the outer one.

Length to end of the elytra 3-3}, breadth 1-2 millim.

Hab. Mxxico, Cordova (Sallé).

Five examples. In some of these specimens the anterior tibie are more strongly

bowed inwards than in others; the former, no doubt, are males. All have the palpi,

antenne, and pygidium similarly formed. Labelled Mordella iridescens, Chevr., in the

Sallé collection.

TOMOXTA.

Tomoxia, Costa, Fauna Regn. Napol., Col. Eter. Mord. p. 8 (1854); Lacordaire, Gen. Col.

v. p. 609.

Four species are here referred tc this genus: two of these agree exactly in their

general structure with the European type of the genus; the other two differ in having

the scutellum less transverse, the middle tibiee a little longer (not, however, exceeding

the entire tarsus in Jength), the penultimate joints of the anterior and middle tarsi

feebly dilated, and the last joint of the maxillary palpi not so stout. The North-

American 7. bidentata (Say) has the penultimate joints of the anterior and middle

tarsi broader, and the eyes not extended to the occiput or lateral margin. In the

European 7’. biguttata the eyes are hairy; but in 7. didentata and the species here

described they are apparently bare.

TOMOXTA. . 261

a. Scutellum about twice as broad as long, emarginate behind ; penultimate joints of the

anterior and middle tarsi filiform ; middle tibie shorter than the tarsi of the same

pair of legs; last joint of the maxillary palpi stout, subsecuriform ; head mode-

rately convex.

1. Tomoxia spinifer. (Tab. XI. figg. 8,2; 8a, hind leg, d .)

Short, broad, black; the head and prothorax with brown or griseous pubescence, that on the disc of the

prothorax in light-coloured examples indeterminately darker; each elytron with a transverse or oblique

spot of variable size on the middle of the disc a little beyond the middle—sometimes interrupted or in the

form of an irregular angulated fascia, sometimes reduced to a small spot,—the suture, the base broadly in

some examples, and, rarely, some markings at the apex, yellowish-grey- or griseous-pubescent, the rest of

the surface with blackish or blackish-brown pubescence. Head exceedingly broad, moderately convex, the

eyes reaching to the occiput; last joint of the maxillary palpi large, its outer and apical sides about equal

in length, and each nearly twice as long as the inner side; antennz moderately long, in the male slender,

with the joints 5-10 feebly serrate, longer than broad, in the female shorter, with the joints 5-10 broader

and more serrate, the penultimate ones about as broad as long, the apical joint scarcely emarginate on the

inner side towards the tip; prothorax broadly and shallowly emarginate in the middle behind; scutellum

transversely subquadrate, about twice as broad as long, emarginate in the middle behind; elytra broad,

short, only about twice as long as the prothorax; epipleure broad at the base, but abruptly narrowed a

little behind the anterior limit of the hind coxe; pygidium moderately long, extending some distance

beyond the hypopygium, a little shorter in the female, truncate at the apex ; anterior and middle tarsi

very slender and filiform, the penultimate joints not in the least dilated; middle tibie about the length of

joints 1-4 of the tarsi of the same pair of legs; hind legs stout, the tibize as long as the basal two joints of

the tarsi united; anterior tibia curved inwards from the base and the hind trochanters produced into a

stout curved tooth in the male.

Length to the end of the elytra 43-5}, to tip of the pygidium 53-6, millim. ; breadth 24 millim. (3 2.)

Hab. Nicaragua, Chontales (Belt); Panama, Bugaba, Volcan de Chiriqui (Champion).

Seven examples. This species resembles the European 7. biguttata, Gyll., with

which it agrees exactly in the form of the tarsi, scutellum, &c.; but it is much broader

than that insect, and the elytra are relatively very much shorter. The reflexed limb of

the.elytra (viewed from the side) is very strongly sinuate; the hind coxe are enormously

developed; the pygidium is of similar form to that of 7’. diguttata. The amount of

griseous pubescence varies considerably: in the single specimen from Chontales it is

more extended, occupying the basal third of the elytra, and the post-median fascia 1s

larger, and there are some markings at the apex; in one or two of the Chiriqui

examples it is reduced to a very small spot behind the middle of the disc of the elytra,

the rest of the pubescence being dark brown. 7. muriniceps, Chevr., from Colombia,

is apparently an allied species, but the brief diagnosis given by its author does not.

agree in several particulars with 7. spinifer.

9. Tomoxia contracta. (Tab. XI. fig. 9, 2.)

Short, moderately broad, black; the head and prothorax clothed with cinereous pubescence, the prothorax’’

with a median vitta and a triangular spot on either side of it blackish-brown-pubescent ; the elytra with

a large oblong sublateral median patch, the suture, and the apex rather broadly, cinereous, the rest of the

surface blackish-brown-pubescent ; the pygidium cinereous-pubescent, blackish-brown along the centre.

Head very broad, the eyes reaching to the occiput; last joint of the maxillary palpi large, subsecuriform ;

262 HETEROMERA.

antenn ( 2 ) short, joints 5-10 moderately serrate, 9 and 10 subtransverse ; prothorax broadly emarginate

in the middle behind; scutellum twice as broad as long, emarginate in the middle behind; elytra only

about twice as long as the prothorax; pygidium (@) very short, rather broadly truncate at the apex;

anterior and middle tarsi very slender, filiform ; middle tibie barely equalling in length joints 1-4 of the

tarsi of the same pair of legs.

Length to end of the elytra 84, to tip of the pygidium 33, millim.; breadth 13 millim. ( 9.)

Hab. Panama, Bugaba (Champion).

One female example. Very much smaller and relatively narrower than 7. spinifer ;

the pygidium shorter and more obtuse in the female; the thorax and elytra differently

marked. ‘The elytral markings are very sharply defined.

b. Scutellum subquadrate, as long as broad, not emarginate behind; penultimate joints

of the anterior and middle tarsi feebly dilated, spongy-pubescent beneath ; middle

tibie as long as the tarsi of the same pair of legs; last joint of the masxillary .

palpi elongate-triangular ; head very convex.

3. Tomoxia fulviceps. (Tab. XI. fig. 10, ¢.)

Elongate, black ; the head densely clothed with fulvous or golden-brown pubescence, the pubescence becoming

darker in the middle and paler at the sides; the prothorax with a rather broad median vitta extending

from the base to the apex, and widened in front, and an elongate-triangular mark or stripe on either side of

it (extending from the base to beyond the middle), from which a short branch extends outwards, and meets

an oblique stripe placed near the anterior margin, these markings for the greater part brownish-black,

but becoming fulvous towards the anterior margin, the rest of the surface yellowish-cinereous-pubescent ;

the elytra with interrupted lines of cinereous pubescence extending to about a fourth from the apex, the.

apical fourth uniformly brown or fulvous-brown-pubescent, an oblique ill-defined brownish stripe extending

from the shoulders downwards, the rest of the surface clothed with blackish pubescence. Head very

convex, the eyes extending to the occiput ; palpi testaceous, the last joint of the maxillary pair elongate-

triangular, its outer side concave, its inner side a little longer than the apical side; antenna ( ¢ ) testaceous,

darker towards the apex, rather slender, joints 5-10 feebly serrate, longer than broad; prothorax rounded

in the middle behind; scutellum quadrate, about as long as broad; elytra a little flattened on the dise,

about two and a half times as long as the prothorax, the humeri somewhat swollen ; pygidium ( ¢) short,

rather broadly truncate at the apex; beneath cinereous-pubescent, the pubescence on the hind coxe and on

the last ventral segments yellowish or fulvous in colour; legs black, the knees and the base of the anterior

femora obscure testaceous, the tibial spurs testaceous; anterior and middle tarsi with the third and fourth

joints slightly dilated; middle tibie as long as the tarsi of the same pair of legs; posterior tibial spurs

very long, the inner one much longer than the outer; the anterior femora and tibie (¢ ) slightly curved.

Length to end of the elytra 53-64, to tip of the pygidium 63~73, millim.; breadth 21-23 millim. (<¢.)

Hab. Mexico, Teapa in Tabasco (/. H. Smith); Nicaracua, Chontales (Belt).

Three examples, all males. In its elytral markings this elegant insect somewhat

approaches the North-American 7. lineella, Lec., but the latter has not the apical

fourth of the elytra uniformly brown-pubescent, and also differs in numerous other

particulars.

4, Tomoxia interrupta. (Tab. XI. fig. 11.)

prothorax with a median vitta (narrowing in front and behind) and a large triangular mark on either

side of this about the middle brownish-black, the rest of the surface with golden-cinereous pubescence, the

pubescence whitish along the lateral margins ; elytra with rather broad partly confluent lines of yellowish-

cinereous pubescence, interrupted by an oblique spot on either side of the scutellum at the base, two

parallel oblong marks below this, a quadrangular spot on either side of the suture about the middle,

and an anteapical patch, these markings brownish-black-pubescent, the apical two-thirds of the suture

cinereous. Head very convex, the eyes extending to the occiput; palpi coloured and formed as in

Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith); Paxama, Bugaba (Champion).

Two examples, agreeing exactly with each other, apparently both males. Smaller

than 7. fulviceps; the markings of the upper surface very different; the anterior and

middle femora entirely flavo-testaceous.

GLIPA.

Glipa, Leconte, Col. of Kansas & Eastern New Mexico, p. 17 (1857).

The characters of this genus as given by Leconte are:—‘ The last joint of the

maxillary palpi strongly dilated, securiform (in the form of an isosceles triangle,

attached by its apex); the outer joints of the antenne triangular; the scutellum

triangular, rounded at the apex; the middle tibiz longer than the tarsi; the posterior

tibiee only moderately dilated, longer than the first joint of the tarsi, and destitute of

oblique ridges; the anal style short, truncate, and subemarginate; the body slender.”

The single species included in it by Leconte, Mordella hilaris, Say, also inhabits

Central America. J. B. Smith, in his “ Monograph of the Mordellide of the United

States” (Trans. Am. Ent. Soc. x. pp. 73 e¢ seg.), merges the genus Glipa into Tomoxia :

he overlooking altogether the abnormally elongate middle tibiz, the very long elytra,

and other characters. The thorax is much broader than the elytra; the elytra are

very elongate (relatively longer than in Tomoaia or Mordella), with the sides almost

straight, but gradually converging from the base ; the anterior and middle tarsi have

their third and fourth joints moderately dilated, and (with the base of the second)

spongy-pubescent beneath; the eyes are finely granulated and pubescent. Various

species from the tropical regions of the Old World belong to it; and two from Brazil

have been described by Chevrolat.

Hab. Nortu America, Indiana!, Middle and Western States? 4, Florida ®>.—Mexico,

Three specimens of this species have been received from Central America. They

agree well with a female example from the United States kindly forwarded by Dr. Horn.

The elytral rmarkings are variable, but the general pattern is constant; the head is

angularly extended beyond the eyes; the anterior femora are more or less testaceous

towards the base. ‘The Nicaraguan specimen is of the male sex: it has the anterior

tibie bowed inwards from the middle; the anterior femora and the basal portion of the

anterior tibiz fringed with long hairs within; and the fifth ventral segment broadly

and deeply excavate along the centre from the apex nearly to the base. Schwarz’s

description of G. hieroglyphica® is evidently based upon male examples, as he mentions

the excavate fifth ventral segment ; he gives as a possible male-character “ penultimate

joint of the maxillary palpi fringed internally with dense whitish pubescence,” but this

is not evident in the Nicaraguan male.

“MORDELLA.

Mordella, Linneus, Syst. Nat. 10th edit. 1. p. 420 (1758); Lacordaire, Gen. Col. v. p. 609.

Sphalera, Leconte, Col. of Kansas & Eastern New Mexico, p. 17 (1859).

This genus contains an immense number of species from all parts of the world, and

it is, no doubt, more numerously represented in tropical than in temperate regions.

One only has hitherto been recorded from within our limits, whence fifty-eight are now

enumerated ; nineteen only are known from America north of Mexico. Comparatively

few species of Mordelia have been described as yet from Tropical South America (and

those chiefly Brazilian); but some hundreds must exist there. As in Tomozia, two

groups of species are indicated—one with the penultimate joint of the four anterior

tarsi dilated and excavate (as in the type of the genus), and the other with this joint

simple. Both groups include species with the antenne clavate and species with the

antenne only moderately widened or slender. Upon a member of the clavate series

(with dilated penultimate tarsal joints) Leconte founded (and subsequently abandoned)

his genus Sphalera.. The form of the fourth antennal joint is an important specific

character in this genus, but, like that of the tarsi, it seems to have escaped the

notice of authors. The antenne in most of the species differ very little sexually; in

M. chevrolati the apical joint is elongated in both sexes, and is longer in the male than

in the female. The last joint of the maxillary palpi varies greatly in shape according

to the species, and in a few cases differs sexually: in the male of UZ. biformis it is

securiform, and very much broader than in the female; in the male of IZ. fenestrata

MORDELLA. 265

it is quadrangular, and more than twice as broad as long. In one or two species the

thorax and pygidium are black in the male and rufous in the female; in two or three

others, of small size, there is a trace of a faint carina on the outer edge of the hind

tibia. All the species here referred to Mordella have the hind tibiz without oblique

ridges on their outer face (the short subapical one excepted), the scutellum triangular,

and the eyes finely granulated. The antenne vary in shape according to the species

from clavate to subfiliform, and the pygidium from short and obtuse to long and

acuminate. The eyes very nearly or quite reach the occiput in all the Central-

American species, the head, at most, being very narrowly extended behind them. A

few of the species with a simple penultimate joint to the four anterior tarsi have

the intermediate tibie distinctly shorter than the tarsi of the same pair of legs (the

reverse being the case in the genus Gilipa); and in certain of the species with a simple

penultimate tarsal joint the antenne have some of the joints (the apical one or two, or

joints 5—7 or 6 and 7) yellow, and the preceding or following joints black. MU. fenestrata

is perhaps generically distinct from Mordella; but as Mordellistena includes species

with the palpi somewhat similarly shaped in the male it is inadvisable to separate it.

The three species here placed at the head of the genus, all of very large size, have a

strong oblique callus extending from the shoulders downwards towards the suture, the

disc of the elytra thus appearing to be flattened or depressed. VW. quadrisignata varies

to a great extent in the size and shape of the pubescent spots on the elytra and also

in the colour of the pubescence of the under surface. In this insect, as in the majority

of the Mordelle, the markings of the thorax and elytra are formed entirely by the

arrangement of the pubescence; but in several of the species here described the

markings are derived from the ground-colour. The eyes are clothed with a short erect

pubescence in many species: this pubescence, however, is easily abraded, and is only

visible in fresh examples.

The following table will assist in the identification of the Central-American

species :—

some species stouter in the male.

de Chiriqui, Tolé (Champion).—Brazin ! 234567,

A variable species. Two forms occur :—(1) The elytra each with two small silvery-

or golden-pubescent spots placed obliquely some little distance below the base and a

transverse crescent-shaped larger mark at about one-third from the apex (M. imperator,

Cast.); (2) the elytra with only the anteapical crescentiform mark (I. clavicornis,

Kirby, J. lunata, Sturm). Examples of both forms are before me from British

Honduras, Nicaragua, and the State of Panama, and also from Brazil. J. clavi-

cornis is closely allied to IZ. guadrisignata, but differs in its elytral markings and in

having the oblique humeral callus more prominent, and continued for at least three-

fourths of the length of the elytra, enclosing a large elongate-triangular depressed

space. The pygidium is more compressed at the sides, more sharply pointed, and, if

anything, longer; in the male it is more than twice the length of the hypopygium.

The underside is in most specimens entirely black ; but in a few of the var. imperator

the sides or base of the ventral segments have a little whitish or golden pubescence.

The other characters are very much the same as in MW. quadrisignata. The length of

the insect, from the front of the thorax to the tip of the elytra, varies from 64-103

millim., the pygidium from 3-5 millim.

2. Mordella quadrisignata. (Tab. XI. figg. 14-18.)

Mordella quadrisignata, Chevr. Col. Mex., Cent. i. fase. 3, no. 55 (1834) *.

An exceedingly variable species, as regards the colour—fulvous, ochreous, golden-

yellow, or ashy—and size of the elytral and thoracic pubescent spots, those on the

thorax being sometimes entirely absent, and those on the elytra being sometimes

greatly enlarged, and sometimes much reduced in size, the anterior one occasionally

entirely obsolete.

Eight well-marked forms occur :—

a. The elytra each with two rounded spots of moderate size (the posterior ones usually the largest) and a faint

or small scutellar patch golden-yellow- or ochreous-pubescent ; the thorax with the base on either side of

the scutellum and a very faint curved or angular line on either side of the disc anteriorly (often oheolere)

ashy-pubescent. This is the form described by Chevrolat!. (Fig. 14.) .

Hab. Mexico, Vera Cruz! (Sal/é); Guatemaza, San Juan in Vera Paz (Champion) ;

Nicaragua, Chontales (Janson, Belt); Panama, Volcan de Chiriqui (Champion).

3. The elytral spots ashy or whitish, smaller, sometimes very small, the scutellar patch usually present; the

thorax usually with a triangular spot on either side at the base and a “t-shaped line on either side of

the disc anteriorly whitish-pubescent. (Fig. 15.)

6. The elytral spots golden-yellow, ochreous, or fulvous, still larger—the anterior ones rounded or slightly

oblong, the posterior ones showing a tendency to form a broad fascia interrupted at the suture,—the

scutellar patch large; the thoracic markings larger and more distinct, the triangular mark at the base

extending forwards and nearly meeting the anterior 1-shaped mark, so as to partly enclose a large spot

of black pubescence. (Fig. 16.)

posterior ones in the form of a broad anteapical fascia narrowly interrupted at the suture; the thorax

without markings,

Hab. Guatemata, Capetillo, Duefias, San Gerénimo (Champion).

Three examples.

6. As in y, but with the posterior spots narrowing behind and extending nearly to the apex (occupying nearly

a third of the entire length of the elytra). (Fig. 18.)

Hab. Mexico, Cordova (Sallé), Cerro de Plumas (Hége).

Three examples.

This is one of the finest of the Central-American species of Mordellide. There can

be no doubt that the various forms all belong to one and the same species, the large

number of examples (fifty) before me being connected one with another by numerous

gradations. Two or three of the varieties occur in the same localities. The light-

MORDELLA. 271

coloured pubescent spots at the sides of the ventral segments and on the sides of

the breast are equally variable :—in a, 6, 8, « they are more or less well marked, in

y, ¢ 9 they are altogether obsolete, and in » they are very small or quite obliterated.

The antenne in both sexes have their joints 5-10 broadly serrate, 7-10 being very

/strongly transverse ; the head is very narrowly extended behind the eyes and distinctly

canaliculate; the elytra are flattened on the disc, and have a long oblique humeral

callus; the pygidium is very long and acuminate (in some specimens fully equalling

half the length of the elytra), only a little shorter in the female, about twice the length

of the hypopygium ; the penultimate joints of the anterior and middle tarsi are mode-

rately widened; the anterior tibie are slightly curved in the male; the last joint of

the maxillary palpi is triangular, not very stout. Var. 6 bears the name U/. terminalis,

Chevr., in the Sallé collection. The insect varies in length from 74-104 millim.

(pygidium excluded), the pygidium from 3-44 millim.

8. Mordella picta. (Tab. XI. figg. 19-21.)

Mordella picta, Chevr. in Guérin’s Icon. Regn. Anim., Ins. p. 130, t. 34. figg. 7, 7 a-c’.

Like MZ. quadrisignata, Chevr., a very variable species, as regards the colour—ashy,

golden, or fulvous—and pattern of the thoracic and elytral pubescent markings. ‘The

insect is apparently much rarer than J. quadrisignata ; but the few examples received

of the different forms clearly run one into the other, though none of them agree exactly

in the elytral markings with the type. The following variations occur :—

a. Head, two transverse lines on the thorax—one along the base, the other towards the anterior margin,

the latter with a short line extending downwards on either side of the middle,—the scutellum, the

commencement of the suture, two punctiform spots towards the middle, and two fascize—the first

elbowed, the second widened in front, without reaching the suture,—cinereo-pubescent.

Hab. Guiana, Cayenne !.

3. Head, three transverse lines on the thorax—one along the base, rather broad, the others narrow, one

towards and the other along the anterior margin,—the scutellum, an oblique stripe on the disc before

the middle—very nearly coalescent with an oblong antemedian sutural patch (forming with this and the

oblique mark on the opposite elytron a large V-shaped mark), and with a transverse ramus in front

extending outwards,—an anteapical fascia (narrowing outwardly), and the suture from the base to the

antemedian patch and from this to the anteapical fascia yellowish-cinereous, (Fig. 19.)

Hab. Panama, San Feliz in Chiriqui (Champion).

One example.

y. Head in front and narrowly along the base, three transverse lines on the thorax—one at the base, rather

proad, one a little distance before and another along the anterior margin, both narrow, the former with a

short line on either side of the middle extending downwards,—the suture nearly to the middle, broadly

so behind, a punctiform spot on the disc a little below the base, a faint transverse mark between this and

the lateral margin, and a broad anteapical fascia, nearly reaching the suture and excised on its anterior

edge, yellowish-cinereous; the scutellum black. (Fig. 20.)

Hab. Nicaraeua, Chontales (Belt).

One example.

272 HETEROMERA.

5. The markings ashy, golden, or fulvous, those on the thorax partly or almost entirely obliterated ; the

sutural stripe extending to the anteapical fascia, the former widened at the middle, the latter broad and

extending completely across, the other markings on the dise towards the base obsolete; the scutellum

black. (Fig. 21.)

Hab. Mexico, Orizaba (Sallé) ; GuatemaLa, Coban (Conradt).

Four examples, three from Guatemala, one from Mexico.

The amount of cinereous pubescence on the sides of the ventral segments and meta-

sternum is also variable, the pubescence on the underside being sometimes entirely

black, sometimes in great part cinereous. The oblique humeral callus is prominent

and continued nearly to the apex of the elytra (the sutural region appearing to be

much depressed, owing to the convexity of the adjoining portion of the elytra); but it

is less distinct in the single female specimen received. The pygidium is strongly

compressed at the sides; in the male it is very long and acuminate, two or three times

the length of the hypopygium, and not very much shorter than the elytra (measuring

from 5-6 millim.) ; in the female it is more obtuse at the tip, and a little shorter,

though more than twice the length of.the hypopygium. The length of the insect,

from the front of tbe thorax to the tip of the elytra, varies from 7-10 millim.

M. picta is allied to M. quadrisignata and M. clavicornis, but differs from both in its

very much more slender antenne, as well as by the elytral markings. ‘The elytra

appear to be more narrowed behind in the male than in the female. The head is very

narrowly extended behind the eyes.

transverse. In six specimens of small size from the State of Panama the antennal

joints 5-11 are less widened, and 11 is very little narrower.than 10; these examples

are connected by intermediate forms and apparently belong to the same species. The

pygidium varies in length, but it is usually short and blunt at the tip in both sexes.

In the single specimen (of large size) from the Volcan de Irazu the antenne are still

more strongly clavate, and the pygidium is longer than usual; others from Oaxaca,

collected with the ordinary form, also have the pygidium unusually elongate; two

from Guatemala (Sai/é) have traces of a median groove on the upper portion of the

head. The second joint of the maxillary palpi is more slender than in MW. scutellaris.

The genus Sphalera, Lec., was based upon this species. Like many other Vordelle,

M. melena varies very greatly in size.

5. Mordella metallica. (Tab. XI. fig. 22.)

Short, broad, metallic bluish-green with brassy reflections, the upper surface rather sparingly punctured,

sparsely clothed with blackish pubescence, the pubescence on the pygidium, scutellum, head, and anterior

margin of the prothorax cinereous. Head obsoletely canaliculate behind, emarginate in the middle at

the base ; palpi testaceous, the last joint of the maxillary pair darker, the latter stout, cultriform ;

antenne with the basal five joints testaceous, the rest black, very short and clavate, joint 5 triangular,

much wider than 4, 6-11 broadly widened and forming a compact club, 7-10 more than twice as broad as

long ; prothorax bisinuate and with a projecting median lobe in front, distinctly depressed within the

basal margin on either side of the middle; scutellum large, triangular ; elytra more than twice as long

as the prothorax, rather convex, gradually narrowing from the base, the suture a little depressed beyond

the middle ; beneath cinereo-pubescent, the sides metallic green, the ventral segments more obscure;

pygidium very short and stout, truncate at the apex, about one and a half times the length of the

hypopygium ; legs black, rather stout.

Length to end of the elytra 5, to tip of the pygidium 54, millim.; breadth 23 millim.

Hab. Mexico, Playa Vicente (Sal/é).

This peculiar species agrees very closely with the description of the European

M. viridipennis, Muls.; but it is evidently much broader in shape, and has more

clavate antenne and a much shorter pygidium. ‘The only other American species of

Mordellide known to me with similar coloration is Cothurus iridescens. The pubes-

cence of the upper surface is rather sparse and it does not hide the punctuation, which

is only moderately dense upon the elytra and more diffuse and finer upon the thorax.

One specimen only has been received ; it is probably a female.

6. Mordella zruginosa, (Tab. XI. fig. 23.)

Elongate, rather broad, cuneiform, black; the head clothed with coarse ashy-eruginous pubescence ; the

prothorax with two narrow parallel black lines on the middle of the disc (nearly reaching the base), for

the rest thickly clothed with coarse ashy-eruginous or eruginous pubescence; the scutellum and elytra

eeruginous-pubescent ; the latter with a rather broad angulated fascia just beyond the middle, two

narrow parallel slightly oblique stripes on the disc extending from the base to the fascia, a short

oblique humeral stripe, the suture very narrowly, and the apex black; the pygidium ashy- or ashy-

seruginous-pubescent, with a narrow black line along the middle. Head obsoletely canaliculate ; last

joint of the maxillary palpi long and stout, cultriform, its apical and outer sides subequal, fully twice

the length of the inner side; antenna black, the basal four joints testaceous or fusco-testaceous, joints

3 and 4 slender, 5-11 very broadly flattened, 5-10 strongly serrate, 5 more than twice the width of 4 and

longer than 6, the penultimate joints strongly transverse; elytra moderately long; beneath and the legs

eeruginous-pubescent; pygidium rather stout, moderately long, blunt at the tip, about twice the length

of the hypopygium ; legs, including the tibial spurs, black.

Length to end of the elytra 54-6, to tip of the pygidium 64-7, millim. ; breadth 23-23 millim.

Hab. Mrxtico, Cordova (Sal/é).

Two examples only of this remarkable species have been received; these agree

precisely with each other in their external characters, though they are apparently male

and female. The pubescence is dense, coarse, and scaly, and of a pale bluish-

verdigris colour, but in certain lights it appears to be cinereous. No species of

Mordella with similarly coloured pubescence is known to me. The antenne are

broadly flattened and serrate from the fifth joint.

7. Mordella dilaticornis. (Tab. XI. figg. 24; 24a, antenna.)

Elongate, cuneiform, black; densely cinereo-pubescent, the pubescence on the prothorax yellowish in tint ;

the prothorax with four small black spots placed transversely (two close together on the middle of the

disc behind and two external to these a little more forward), the elytra with a small spot on either side

of the suture near the base, a transverse fascia just beyond the middle, not reaching the suture and

widening outwardly, and the apex, black; the pygidium cinereo-pubescent at the sides, black along the

middle. Head grooved in the middle behind; antenne black with the basal four joints reddish, short

and clavate, joint 5 triangular, very much wider than 4, 6-10 short, widened, broadly serrate, 7--10 about

twice as broad as long; elytra moderately long, rapidly narrowing from the base, flattened on the disc,

declivous laterally, the shoulders prominent, the sides straight; beneath cinereo-pubescent ; pygidium

rather short, twice the length of the hypopygium, obtuse at the tip; legs black, the tibial spurs

pitchy-red.

Length to end of the elytra 6, to tip of the pygidium 7, millim.; breadth 23 millim.

Hab. Panama, Volcan de Chiriqui (Champion).

One example only of this very distinct species was obtained. In the short clavate

antenne it approaches JZ. clavicornis and M. quadrisiqnata, this character separating

it from all the other somewhat similarly marked Central-American species. The spots

or markings of the thorax and elytra are comparatively small, so that by far the

greater portion of the surface is covered by cinereous pubescence. The six outer

joints of the antenne form a compact club.

8. Mordella triangulifer. (Tab. XI. fig. 25.)

Moderately elongate, rather broad, black ; the head, prothorax, and scutellum densely clothed with yellowish-.

cinereous pubescence, the prothorax with a narrow blackish-pubescent stripe on either side of the middle

of the disc (extending almost from the base to a little beyond the middle and widening anteriorly) and a

similarly coloured spot on either side of these externally ; the elytra brownish-yellow or fulvous, with a

very large, broad, triangular common basal patch and the suture narrowly from this to the apex black, in

one example with a broad interrupted postmedian fascia and the apex pitchy-brown, the pubescence in

great part yellowish-cinereous, the triangular basal patch (except along the base and suture) blackish-

pubescent, the apex and the postmedian fascia brown-pubescent; the pygidium yellowish-cinereous-

pubescent, the apical half blackish-brown. Palpi obscure testaceous, the apical joint of the maxillary

MORDELLA. 275

pair subtriangular, not very broad, its inner and apical sides about equal in length, and both much

shorter than the outer side; antennz piceous with the four basal joints testaceous, short, joints 3 and 4

slender, about equal in length, 4 a little stouter than 3, 5-11 widened, 5-10 gradually increasing in

width and decreasing in length, 5 triangular, longer than broad, 6 about as broad as long, 7-10 very

strongly transverse, strongly serrate, 11 subtriangular, narrower and a little longer than 10; elytra

rather short; beneath densely yellowish-cinereous-pubescent ; pygidium short, blunt at the tip, about

twice the length of the hypopygium ; legs, including the tibial spurs, black or piceous, the anterior and

middle femora obscure testaceous.

Length to end of the elytra 3-44, to tip of the pygidium 33-43, millim. ; breadth 13-2 millim.

Hab. Mexico, Cordova (Sallé).

Two examples, one in very good condition, the other denuded of pubescence. In

the structure of the antenne this small species approaches J. clavicornis, M. quadri-

signata, &c. The coloration of the elytra somewhat resembles that of VW. rufovittata,

but I. triangulifer differs greatly from that insect in the form of the antenne and

pygidium. In one specimen the elytra have the apex and a broad post-median fascia

darker, but this is partly formed by the colour and arrangement of the pubescence.

The typical form of this species is black without conspicuous markings. /. érrorata,

Lec., has single intermixed cinereous hairs on the elytra, and a few of the Chihuahua

and Durango specimens exhibit this peculiarity. The longer pygidium, the longer

and non-clavate antennz, and the rounded median basal lobe of the thorax’ distinguish

the species from IM. melena, Germ. The second joint of the maxillary palpi is

unusually stout in both sexes. The outer lobe of the maxille is elongated, very much

as in VV. aculeata, Linn. It is perhaps doubtful if the specimens from the above-

quoted localities really all belong to one species; but I am unable to distinguish more

than one amongst those from Central America.

The identification with the Fabrician species is given on the authority of Leconte 2.

276 HETEROMERA.

10. Mordella signata. (Tab. XI. figg. 26; 26a, antenna; 27, var.)

Elongate, broadly cuneiform, black ; the head cinereous-pubescent ; the prothorax with a broad black median

vitta (extending to the apex but not to the base) and a very large rounded black spot on either side of

this about the middle, for the rest cinereous- or yellowish-cinereous-pubescent; the scutellum cinereo-

pubescent; the elytra with a rather broad angulated fascia at about one-third from the base, extending

upwards and downwards along the suture and reaching the base, and an equally broad transverse lunate

mark on the disc beyond the middle (these markings in one example coalescent at the suture with those

on the opposite elytron, in the other narrowly separated) cinereous- or yellowish cinereous-pubescent,

the pubescence on the rest of the surface black. Head canaliculate; antenne black, reddish towards the

base, rather slender, joints 3 and 4 narrow, 5-11 broader, 5-10 moderately serrate, in the female a little

shorter; prothorax transverse, very little rounded at the sides when viewed from in front; elytra

moderately long, narrowing from the base, more rapidly so in the male, the sides almost straight, the

disc flattened or depressed, the shoulders prominent; beneath cinereous-pubescent, a broad sublateral

band and the last three ventral segments (except laterally in front) black; pygidium long and stout,

not much compressed at the sides, bluntly rounded at the apex, a little shorter in the female.

Var. a. The pubescence on the head darker, fuscous behind, cinereous in front; the light markings on the

prothorax reduced to a line along the base and a sinuous transverse line towards the anterior margin;

the antemedian angulated fascia of the elytra broken up into spots and disconnected from the short

sutural mark at the base, the lunate mark on the disc beyond the middle not reaching the suture (in one

specimen broad, in two others much reduced in size); the pubescence of the under surface in great part

black. (Fig. 27.)

Var. B. Above and beneath black, the head with a little cinereous pubescence in front.

Length to end of the elytra 84-10, to tip of the pygidium 12-133, millim.; breadth 33-43 millim. (¢ 2.)

Hab. Mexico (Sturm, in coll. Sallé), Cerro de Plumas (Hége), Santecomapan (Sal/é) ;

Nicaraaua, Chontales (Belt, Janson).

Seven examples. The description is taken from two well-marked specimens, one

from Chontales and one from Cerro de Plumas; of the var. @ there are three speci-

mens, two from Mexico (labelled M. signata, Sturm, in Sallé’s collection) and one

from Chontales; of the var. 8, two specimens from Santecomapan. ‘This species is

fully as large as MW. picta, from which its distinctly shorter, broader, less compressed,

obtuse pygidium, less prominent humeral callus, &c., distinguish it at once. The

elytra are flattened or slightly depressed on the disc, and the shoulders prominent. In

the male the hypopygium is nearly two-thirds, in the female about half the length of

the pygidium, the latter being a little longer in the male than in the female.

11. Mordella tripartita, (Tab. XII. fig. 1.)

Elongate, broadly cuneiform, black; the head cinereo-pubescent ; the prothorax with a broad black median

vitta (not quite reaching the base or apex) and a large black patch on the disc on either side of it, for

the rest cinereo-pubescent ; the scutellum cinereo-pubescent ; the elytra with three narrow fascize—one

some distance below the base, one a little beyond the middle, and one before the apex, the anterior two

partly interrupted,—and the suture very narrowly from the base to the anteapical fascia, cinereo-

pubescent, the rest of the pubescence black; the pygidium narrowly cinereo-pubescent at the base, for

the rest black. Head somewhat deeply canaliculate ; antenne (¢ ) moderately long, rather stout, joints

3 and 4 narrow, 5-11 broader, 5-10 subserrate, decreasing in length, 9 and 10 not much longer than

broad; elytra moderately long, rapidly narrowing from the base, flattened on the disc, with rather

prominent shoulders, the sides straight ; beneath (and the lower side of the femora) cinereo-pubescent, a

broad sublateral band and the last three ventral segments (except at the sides anteriorly) black ;

MORDELLA. 277

pygidium (¢ ) very stout, moderately long, truncate at the tip, one third longer than the hypopygium ;

legs black, the tibial spurs piceous, the anterior tibie almost straight, the four basal joints of the anterior

and intermediate tarsi rather stout, densely pubescent beneath.

Length to end of the elytra 74, to the tip of the pygidium 94, millim.; breadth 3} millim. (d¢.)

Hab. Mexico, Tehuantepec (Sallé).

One male example only. The trimaculate thorax, trifasciate elytra, stout and

obtuse pygidium, and broad cuneiform shape chiefly distinguish J. tripartita. It is

not very closely allied to any of the other species here described.

12. Mordella arcuata. (Tab. XII. fig. 2.)

Elongate, broadly cuneiform, rather convex, black; the head in part, the sides of the prothorax indeter-

minately, the scutellum, a transverse fascia (sometimes reduced to a spot on either side of the suture) a

little below the base of the elytra—extending upwards along the suture to the base and usually connected

with a short oblique humeral stripe so as to enclose a large spot at the base of each elytron,—and

another fascia a little beyond the middle (widening inwardly and nearly or quite reaching the suture,

its anterior and posterior edges concave) fusco- or olivaceo-cinereous-pubescent, the rest of the pubes-

cence black or brownish-black. Palpi obscure testaceous or reddish, the last joint of the maxillary pair

darker, stout, elongate-triangular, its apical and outer sides about equal in length, each very much

shorter than the inner side; antenne piceous with the basal joints reddish, rather slender, joints 3 and 4

equal in length, 4 a little stouter than 3, 5-11 moderately widened, equal in width, 5-10 serrate,

decreasing gradually in length, longer than broad (10 nearly as broad as long), 11 much longer than 10;

scutellum triangular ; elytra moderately long, rapidly narrowing from the base, distinctly depressed

along either side of the suture; beneath with a little fusco-cinereous pubescence at the base of the first

ventral segment laterally and at the sides of the metasternum, for the rest brownish-black-pubescent ;

pygidium broad and stout (forming almost a continuous line with the sides of the elytra), moderately

long, truncate at the tip, scarcely shorter in the female, not more than one half longer than the hypopy-

gium, the latter comparatively elongate; legs stout, black, the anterior femora reddish at the base, the

tibial spurs piceous.

Length to end of the elytra 53-63, to tip of the pygidium 7-8, millim.; breadth 23-3 millim. (¢ 2.)

Hab. Mexico, Cordova (Sallé), Oaxaca (Hoge); Guatemata, Yzabal (Sal/é).

Five examples. Perhaps nearest allied to WM. tripartita, but with much more

slender antenne, the light pubescence very differently arranged and brownish or olivaceo-

cinereous in colour, and the elytra more convex and distinctly depressed along either

side of the suture. The pygidium is very stout, forming almost a continuous outline

with the sides of the elytra, and truncate at the tip. The specimens in the Sallé

collection are separated into three species, one of them bearing the MS. name of

M. arcuata, Chevr. The post-basal fascia of the elytra is sometimes reduced to a

spot on either side of the suture, so that it becomes disconnected from the short

oblique humeral stripe.

13. Mordella sellata. (Tab. XII. fig. 3.)

Elongate, rather narrow, black; the head densely cinereo-pubescent ; the prothorax with a broad black

median vitta posteriorly (not extending to the base and reaching to a little beyond the middle in front)

and a black triangular spot on either side of it, for the rest densely cinereo-pubescent ; the scutellum

cinereo-pubescent ; the elytra with a common transverse rhomboidal mark a little below the base, a

278 HETEROMERA.

large humeral patch, a broad median fascia (divided at the suture by a very narrow line of cinereous

pubescence), and the apex, rather broadly, black, for the rest densely cinereo-pubescent ; the pygidium

cinereo-pubescent at the base, for the rest black. Last joint of the maxillary palpi moderately stout,

triangular, its inner side shorter than the outer or apical sides; antenne black with the four basal joints

testaceous, joints 3 and 4 slender, 5-11 moderately dilated and serrate, 5 triangular, twice as broad as 4,

9 and 10 transverse ; elytra moderately long ; beneath cinereo-pubescent, the ventral segments marked

with black at the sides, the last three with the apices also black; pygidium moderately long, rather

stout, truncate at the tip, about twice as long as the hypopygium ; legs, including the tibial spurs, black.

Length to end of the elytra 44, to tip of the pygidium 53, millim.; breadth 1? millim.

Hab. Mexico, Tehuantepec (Salié).

One example. In the markings of the upper surface this insect differs considerably

from all the other Mordellw here described. It is, however, closely allied to several

of the following species. The light pubescence is of an ashy-white colour.

14. Mordella albopicta.

Elongate, narrow, black; the head cinereo-pubescent; the prothorax (apparently) with a broad median black

vitta (not reaching the base or apex and widened behind) and a large black spot on either side of it at

the middle, for the rest cinereo-pubescent ; the scutellum cinereo-pubescent; the elytra with the suture

at the base, a short curved stripe on the disc in front (widened behind so as to partly enclose a black spot

and in one specimen extending narrowly along the base to the suture), a short oblique stripe or two spots

below this externally, an oblong spot close to the suture before the middie (connected in one specimen

with the sutural mark at the base), and a rather narrow fascia at one-third from the apex (not reaching

the suture or lateral margin and deeply excised on its anterior edge) cinereo-pubescent, the rest of the

pubescence black ; the pygidium cinereo-pubescent at the base, black beyond. Last joint of the maxillary

palpi as in M, sellata; antenne piceous with the basal four joints fusco-testaceous, short, joints 3 and 4

slender, 5-11 moderately dilated, subserrate, 5 triangular, twice as broad as 4, 6-8 about as broad as

long, 9 and 10 transverse; elytra moderately long; beneath cinereo-pubescent, the sides in part black;

pygidium rather short, moderately stout, blunt at the tip, about twice as long as the hypopygium ; legs,

including the tibial spurs, black, the anterior and intermediate femora and tibiee fusco-testaceous in one

specimen (<¢ ).

Length to end of the elytra 4, to tip of the pygidium 43, millim.; breadth 13 millim. (¢.)

Hab. Mexico, Cordova (Sallé).

Two worn specimens only, one of which is a male. Allied to Jf. sellata, but with

very different cinereo-pubescent markings. The light pubescence is almost white in

one example. Labelled MU. albopicta, Chevr., in the Sallé collection.

15. Mordella tetraspilota. (Tab. XII. fig. 4.)

Elongate, rather narrow, the female broader, black; the head cinereous- or brownish-pubescent ; the pro-

thorax with three broad black or blackish-brown vittee (the median one widened behind, the lateral ones

oblique, the median sometimes divided before the middle by a fine transverse line of cinereous

pubescence), the rest of the pubescence cinereous; the scutellum cinereo-pubescent ; the elytra each

with an elongate oblique spot on the middle of the disc a little below the base, and a subquadrate

transverse spot (not reaching the suture or lateral margin, and sometimes excised on its anterior or

posterior edge) on the disc beyond the middle whitish- or cinereo-pubescent, the rest of the pubescence

blackish-brown ; the pygidium cinereo-pubescent at the base laterally, for the rest black. Last joint of

the maxillary palpi moderately stout, triangular, the inner side much shorter than either the outer or

apical sides; antenne black, the basal three or four joints testaceous, joints 3 and 4 slender, 5-11

subserrate, much longer than broad, moderately dilated, 5-8 a little more distinctly serrate; elytra

moderately long; beneath cinereo-pubescent, the ventral segments black at the apex; pygidium short

and stout, blunt at the tip, not twice the length of the hypopygium in either sex, a little shorter in the

female; legs, including the tibial spurs, black.

Var, The prothorax with a median basal patch and the sides in front alone cinereous; the elytra with a

little additional cinereous pubescence at the extreme apex.

Length to end of the elytra 33-44, to tip of the pygidium 42-53, millim.; breadth 14-13 millim. (¢ 92.)

Hab. Mxxico, Iguala in Guerrero (Hége), Chilpancingo (H. H. Smith), Capulalpam

(Sallé).

Five examples, four of the type and one of the variety. Allied to MW. albopicta and

M. sellata, but with the pygidium still shorter. The elytra have merely a whitish-

pubescent oblique mark before and a transverse spot on the disc beyond the middle ;

in the variety the apices are also whitish-pubescent. The species is apparently confined

to Western Mexico. The variety is from Capulalpam.

16. Mordella leucosticta. (Tab. XII. fig. 5.)

Elongate, rather narrow, black ; the head cinereo-pubescent ; the prothorax with indications of a broad black

median vitta and a large black spot in the middle on either side of it, for the rest cinereo-pubescent ;

the scutellum cinereo-pubescent ; the elytra each with an oblique stripe extending from the shoulder

downwards towards the suture (widened behind into a triangular mark and about reaching to the basal

third of the elytron, but not nearly extending to the suture) and a narrow fascia a little beyond the

middle (not reaching the suture or lateral margin and more or less excised in front and behind) cinereo-

pubescent, the rest of the pubescence black ; the pygidium cinereo-pubescent at the sides in front, for the

rest black. Last joint of the maxillary palpi stout in both sexes, triangular, broader in the male ; antenne

black with the basal three or four joints testaceous, rather long, joints 3 and 4 slender, 4 much longer

than 3, 5-11 moderately widened, much longer than broad, 5 triangular, fully twice as broad as 4, 5-7

in the male a little more distinctly serrate ; elytra moderately long; beneath with the pubescence in

great part black, the sides of the ventral segments in front and the metasternum cinereo-pubescent ;

pygidium rather slender, long and acuminate, about twice the length of the hypopygium; legs black, the

anterior femora in some examples fusco-testaceous, the tibial spurs pale testaceous.

Length to end of the elytra 23-4, to tip of the pygidium 34-54, millim.; breadth 1j-1? millim. (¢ 9.)

Hab. GuateMA.a, San Isidro (Champion); Nicaracua, Chontales (Janson); Panama,

Bugaba, Tolé (Champion).

Six examples. ‘These vary greatly in size, but the elytral markings are constant.

The longer and more slender pygidium and the testaceous tibial spurs distinguish

M. leucosticta from M. albopicta, M. tetraspilota, &c. This is one of several closely

allied Central-American species.

17. Mordella astuta.

Short and narrow, black ; the head, the entire base of the prothorax narrowly, and the elytra with the suture

very narrowly from the base to a little beyond the middle and an ill-defined obliquely placed V-shaped

mark at the base laterally cinereous- or brownish-cinereous-pubescent, the rest of the pubescence

black. Palpi pitchy-brown, the last joint of the maxillary pair darker, the latter triangular, its apical

and inner sides about equal in length ; antenne piceous or black, the basal joints paler, joints 3 and 4

slender, subequal, 5-11 moderately widened, 5-10 serrate, gradually decreasing in length, 9 and 10

280 HETEROMERA.

rather broader than long, 11 short ovate, very little longer than 10; elytra rather short; beneath with

the metasternum, the sides of the posterior coxe in front, and the base of each ventral segment cinereo-

pubescent, for the rest blackish-pubescent ; pygidium long, about twice the length of the hypopygium ;

legs black, the tibial spurs piceous. .

Length to end of the elytra 22, to tip of the pygidium 33, millim.; breadth 1 millim.

Hab. Mexico, Teapa (7. H. Smith); Guatemata, Cahabon in Vera Paz (Champion).

Four examples of this very obscure little species have been obtained. It is perhaps

nearest allied to WM. dimidiata, from which it differs not only in colour but in the

longer antenne and pygidium. The light-coloured pubescence on the elytra is limited

to an obliquely placed V-shaped mark below the shoulder and a narrow line along the

basal half of the suture.

18. Mordella fluctuosa. (Tab. XII. fig. 6.)

Moderately elongate, rather broad, black; the head cinereo-pubescent ; the prothorax with the apex narrowly,

a narrow angulated line in front extending completely across (with the marginal line almost enclosing

three transverse black marks), and a rather large triangular patch at the base on either side of the

middle (extending forwards but not reaching the centre, and also laterally to the posterior angles)

cinereo-pubescent, for the rest black; the scutellum cinereo-pubescent ; the elytra with two narrow

strongly angulated cinereo-pubescent fascize—one some distance before and the other beyond the middle,

the former not reaching the suture and with a short narrow branch laterally extending upwards to the

base, the latter extending completely across and with the portion on the opposite elytron forming a

W-shaped mark,—the suture very narrowly at the extreme base and the apical third with a little

scattered cinereous pubescence, the rest of the pubescence black; the pygidium cinereo-pubescent at the

base, black beyond. Palpi piceous, the last joint of the maxillary pair stout, triangular; antenne

piceous with the basal four joints paler, short and slender, joints 3 and 4 very thin, long, and equal, 5-11

wider, 5 triangular, longer than 4, 6-10 serrate, decreasing in length, the penultimate joints transverse ;

elytra not quite two and a half times the length of the prothorax; beneath in great part cinereo-

pubescent ; pygidium slender, pointed at the tip, moderately long, more than twice the length of the

hypopygium ; legs black, the tibial spurs piceo-testaceous, the anterior tibie curved.

Length to end of the elytra 3, to tip of the pygidium 32, millim.; breadth 14 millim.

Hab. Panama, Volcan de Chiriqui (Champion).

One example, probably of the male sex. Of the size and general appearance of

M. acuticauda, but with very different cinereo-pubescent markings on the thorax and

elytra, short serrate antenne, &c. MM. fluctuosa is perhaps nearest to WM. albo-

picta, but it is less elongate and much smaller; the antenne and pygidium are much

more slender, the elytral markings very different.

19. Mordella acuticauda. (Tab. XII. fig. 7.)

Moderately elongate, the female broader, black, somewhat sparsely pubescent; the head cinereo-pubescent ;

the prothorax with the sides and base and a line along the disc on either side of the middle (not reaching

the apex) cinereo-pubescent, for the rest black; the scutellum cinereo-pubescent; the elytra with three

rather narrow cinereo-pubescent fascize—one at about one fourth from the base, curving forwards at the

sides and extending to the shoulders, one at the middle, angulated or a little excised on its upper or

lower edge, and one some little distance before the apex, the latter curving upwards and confluent with

the opposite one at the suture, the anterior two nearly reaching the suture,—for the rest black; the

pygidium cinereo-pubescent at the base, black beyond. Head very broad and convex, without distinct

median groove ; palpi testaceous, the last joint of the maxillary pair sometimes darker, the latter broad

and subequilaterally triangular in the male, smaller and with the apical side shorter than the inner or

outer sides in the female ; labrum testaceous ; antennz piceous or dark brown with the basal four or five

joints testaceous, slender, joints 3 and 4 very thin, 4 a little longer than 3, 5-11 wider and very feebly

serrate, 11 longer and distinctly stouter than 10; elytra moderately long; beneath with a good deal of

silvery or whitish pubescence ; pygidium long and pointed, compressed laterally, very slender, nearly three

times the length of the hypopygium, only a little shorter in the female ; legs black, the anterior pair (the

tips of the tarsi excepted) and the posterior tibial spurs testaceous, the intermediate pair often piceo-

testaceous, the latter and the anterior pair very slender but with their penultimate tarsal joint very

distinctly dilated.

Length to end of the elytra 23-3, to tip of the pygidium 33—4, millim.; breadth 13-1} millim. (¢ 2.)

Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith); Guaremaua, Senahu, Cachil, and

San Geronimo in Vera Paz (Champion); Panama, Bugaba (Champion).

Numerous examples. The pubescence of the upper surface is rather scanty, and the

ashy- or obscure ashy-pubescent markings are less sharply defined than usual owing to

the dark ground-colour showing through. The markings of the elytra are placed

somewhat as in the North-American WM. triloba, Say (figured by J. B. Smith, in Trans.

Am. Ent. Soc. x. t. 2. fig. 6); but the basal fascia encloses one spot only (instead of

two) on each elytron. The pygidium is very slender, long, and pointed, and by

this character alone /. acuticauda may be separated from all the allied species, the

following excepted.

20. Mordella analis.

Closely allied to M. acuticauda, and only differing as follows:—Smaller; the median fascia of the elytra

broader and straighter, the posterior fascia completely obliterated; the last two or three ventral

segments testaceous or fusco-testaceous ; the pygidium much shorter, not more than twice the length of

the hypopygium.

Length to end of the elytra 27-24, to tip of the pygidium 22-3, millim.

Hab. Panama, Bugaba, Tolé (Champion).

Two imperfect examples. Perhaps only a variety of UM. acuticauda, but in our

series of the latter there is nothing intermediate. UM. amalis resembles M. cingulata

in its markings, but differs totally from that insect in the form of the antenne, the

slender and short pygidium, and the slender legs.

21. Mordella octolineata. (Tab. XII. fig. 8.)

Comparatively short, black; the head, prothorax, and scutellum densely clothed with yellowish-cinereous

pubescence, that on the prothorax intermixed with brown hairs which in certain lights assume the

appearance of four narrow longitudinal stripes; the elytra black, sometimes with an oblique reddish or

fulvo-testaceous spot below the shoulders, each with four narrow, parallel, more or less distinct, oblique

stripes of yellowish-cinereous pubescence extending from the base downwards—two of them extending

to the apex and two of them becoming evanescent at about one-third from the apex,—the rest of the

surface clothed with brownish-black pubescence ; the pygidium blackish-pubescent, cinereous at the base

only. Head almost smooth when denuded of pubescence; palpi testaceous, the last joint of the maxillary

pair a little darker at the tip, the latter elongate-triangular, rather narrow, its inner side longer than the

apical side, each much shorter than the outer side; antenne obscure testaceous, piceous towards the tip,

joints 3 and 4 short, subequal, 5-11 moderately widened, 5-10 serrate, decreasing in length, 5 rather

longer than broad, 6-10 about equal in width, 9 and 10 strongly transverse, 11 short ovate, longer but a

little narrower than 10; scutellum triangular; elytra comparatively short ; beneath cinereo-pubescent,

the ventral segments at the sides behind clothed with dark brown pubescence; pygidium short and

rather stout, blunt at the tip, about twice the length of the hypopygium ; legs stout, black, the anterior

and intermediate femora and tibie testaceous or fusco-testaceous, the tibial spurs piceous.

Length to end of the elytra 34, to tip of the pygidium 4, millim.; breadth 13 millim.

Hab. Mexico, Jalapa (Hoge); GuatemMata, near the city, Capetillo (Champion).

Three examples only of this peculiar little species have been obtained. ‘The arrange-

ment of the elytral pubescence is different from that of all the other Central-American

Mordeile, each elytron having four narrow, parallel, slightly oblique, lines of light

pubescence, and these lines separated by narrow stripes of blackish pubescence; the

Guatemalan examples have a reddish spot below the humerus. I. octolineata has

much the facies of a small Tomoaia, but the scutellum is triangular; the N. American

T. lineella, Lec., seems to have somewhat similar markings.

22. Mordella subdola. (Tab. XII. fig. 9.)

Moderately elongate, black ; the head, the prothorax on all sides indeterminately (and in one specimen the

sides of the disc also), the scutellum, the elytra with the suture and base very narrowly and a very

narrow oblique stripe extending from the shoulder to the middle, and the basal half of the pygidium,

cinereo-pubescent, the rest of the pubescence of the upper surface black. Palpi piceous, the last joint of

the maxillary pair stout, subcultriform, its outer and apical sides about twice the length of the inner

side; antenne piceous, the basal four joints paler, joints 3 and 4 slender, subequal, 5-11 moderately

widened, longer than broad, differing very little in length, 5-10 subserrate; elytra moderately long,

flattened on the disc ; beneath with the metasternum, the sides of the hind coxe in front, and the base

of each ventral segment cinereo-pubescent, for the rest blackish-pubescent ; pygidium rather short, not

very stout, blunt at the tip, twice the length of the hypopygium ; legs black, the tibial spurs obscure

testaceous.

Length to end of the elytra 4, to tip of the pygidium 5, millim. ; breadth 13 millim.

Hab. Mexico, Juquila and Yolotepec, both in Oaxaca (Sal/é).

One worn example only from each locality. Easily separable from most of the

Mordelle here described by the suture being narrowly cinereo-pubescent from the base

to the apex ; on each elytron there is also a very narrow oblique slightly interrupted line

of cinereous pubescence extending from the shoulder to. the middle. The antenne are

longer and less strongly serrate than in W/. astuta, from which it also differs in the form

of the last joint of the maxillary palpi. |

Perhaps a variety of the North-American MW. obliqua, Lec. (Proc. Am. Phil. Soc. xvii.

p. 428, fig.), from the figure of which it only seems to differ in having a shorter and

more oblique discoidal stripe on the elytra. MV. obliqua is treated by J. B. Smith in his

‘ Monograph’ as a variety of M/. lunulata, Helm. ; the type of MW. obliqua is also figured

by him (Trans. Am. Ent. Soc. x. t. 2. fig. 1).

MORDELLA. 283.

23. Mordella chevrolati. (Tab. XII. figg. 10,3; 10a, antenna, 3.)

Comparatively short, black, the punctuation of the upper surface very dense and granular; the head with a

large broad-ovate brown-pubescent patch in the middle (extending to the base and apex), the sides with

silvery-white pubescence ; the prothorax with the sides and a triangular mark on either side of the

middle at the base silvery-white-pubescent, the pubescence between and just in front of these marks

brownish-black, for the rest golden- or fulvous-brown ; the scutellum with blackish-brown pubescence ;

the elytra brown-pubescent, each with a very large oblong patch of black or blackish-brown pubescence

on the disc extending from the base to the middle (not reaching the suture or lateral margin and narrow-

ing behind) and enclosing two oblong, slightly oblique, silvery-white-pubescent spots; the pygidium

silvery- or cinereo-pubescent, with a line of brown pubescence along the middle. Palpi obscure testaceous,

the last joint of the maxillary pair broadly triangular in both sexes; antenne pitchy-brown with the basal

joints testaceous, long and slender in both sexes, joints 3 and 4 thin, subequal, 5-11 broader but very

little widened, much longer than broad, 5-10 decreasing in length, only feebly subserrate, 11 in the male

considerably more than, in the female nearly, twice as long as 10; elytra rather short; beneath silvery-

white-pubescent, the pubescence on the inner portion of the posterior coxe blackish-brown; pygidium

rather short in both sexes, blunt at the tip, a little more than twice the length of the hypopygium; legs

black, the anterior femora and tibis, the intermediate femora, and the tibial spurs testaceous, the inner

posterior tibial spur very long.

Length to end of the elytra 34-33%, to tip of the pygidium 33-43, millim.; breadth 1% millim. (¢ 9.)

Hab. Mexico, Cordova (Sallé); Guatemata, Yzabal (Salié), Teleman and San Juan

in Vera Paz (Champion).

Four specimens, all from the Atlantic slope of Southern Mexico or Guatemala.

This handsome species differs from all other JMordelle known to me in having the

apical joint of the antenne more than twice the length of the tenth in the male, the

antenne themselves being very slender. The two oblong silvery-pubescent spots on

each elytron and the triangular basal mark on the thorax are placed in an oblique line

and are almost equidistant from each other; these spots being surrounded by blackish

pubescence are very conspicuous. Labelled with the preoccupied name of MM. albo-

_ guttata, Chevr., in the Sallé collection.

24, Mordella sexnotata. (Tab. XII. fig. 11.)

Comparatively short, black, very densely and somewhat roughly punctured ; the head broadly brown-pubescent

along the middle, the sides with silvery-white pubescence ; the prothorax with a line along either side of

the middle extending for two-thirds of its length, widening behind and forming an elongate-triangular

mark, the basal margin very narrowly, and the sides silvery-white-pubescent, for the rest clothed with

blackish pubescence (this being nearly separated into three broad vitte by the white pubescence, and

becoming browner in front); the scutellum blackish-pubescent ; the elytra with more than the apical

half brown-pubescent, each with a very large blackish basal patch (extending laterally almost to the

middle and reaching the suture at the base, but cut off obliquely behind from a little below the base), this

patch almost enclosing three triangularly-placed silvery-white-pubescent spots—one, almost rounded, near

the base, one, in the form of a short oblique stripe, below the shoulder, one, triangular, on the disc, below

and more distant from the suture than the basal one,—the shoulders with a little brown pubescence ;

the pygidium silvery-pubescent, with a line of brown pubescence along the middle. Head, eyes, and

palpi as in M. chevrolati, the antennz formed as in the female of that species, but a little more slender ;

beneath silvery-white-pubescent ; pygidium and legs much as in WM. chevrolati, the latter a little more

slender.

Length to end of the elytra 23, to tip of the pygidium 3, millim. ; breadth 1 millim.

284 HETEROMERA.

Hab. Panama, Bugaba (Champion).

One example, which, from the form of the apical joint of the antennae, is probably

of the female sex. Perhaps a small varietal form of M. chevrolati, but differing from

our four examples of that species in the markings of the thorax and elytra: the tri-

angular silvery patch on either side of the middle of the thorax at the base is continued

forwards to beyond the middle, so as to partly divide the blackish pubescence into three

vittee, this pubescence being very much darker than it isin UM. chevrolati; the elytra

have an additional silvery spot under the shoulder, the two other spots are less elongate

and more obliquely placed, and the blackish pubescence on the basal half extends to

the lateral margin.

25. Mordella dimidiata, (Tab. XII. fig. 12.)

Moderately elongate, black, the prothorax usually entirely rufous—sometimes with the base very narrowly or

the basal half, sometimes entirely, piceous; the head cinereo-pubescent ; the prothorax bordered with

cinereous pubescence at the base, the pubescence of the rest of the surface partaking of the ground-colour

or brown in dark-coloured specimens; the scutellum brownish- or cinereo-pubescent; the elytra with a

little more than the apical half uniformly brown-pubescent, a line of cinereous or brownish-cinereous

pubescence extending upwards along the suture to the base and continued along it to meet a longitudinal

line of pubescence running from the base downwards on the outer portion of the disc, this latter not

reaching the brown pubescence but abruptly ending and with an oblique branch running upwards from

its point of termination to a little below the shoulder, the rest of the pubescence on the basal portion

black ; the pygidium cinereo- or fusco-pubescent. Last joint of the maxillary palpi piceous, not very

broad, subtriangular, its outer side much longer than the inner or apical sides; antenne black with the

basal joints obscure testaceous, short, joints 3 and 4 narrow, subequal, 5-11 wider and moderately dilated,

5-10 serrate, decreasing in length, 8-10 transverse ; elytra moderately long, shorter in some specimens ;

beneath in great part cinereo-pubescent, the ventral segments (except in the middle) black along their

posterior half; pygidium rather slender, moderately long, shorter in the female, blunt at the tip, in the

male more than twice the length of the hypopygium ; legs black, the tibial spurs piceous, the anterior

coxee and femora usually paler in colour, the posterior tibial spurs comparatively short.

Length to end of the elytra 23-4, to tip of the pygidium 3-5}, millim.; breadth 13-12 millim. (¢ 9.)

Hab. Mexico, Jalapa, Cerro de Plumas (Hége), Teapa in Tabasco (H. H. Smith);

Guatemala, Cahabon (Champion); Nicaraeua, Chontales (Janson); Panama, Volcan de

Chiriqui, Caldera, San Lorenzo (Champion).

Widely distributed but apparently scarce, one or two examples only having been

found at each locality. This species differs from all the other Central-American

Mordelle in the arrangement and colour of the pubescent markings on the elytra.

The thorax is usually rufous, rarely piceous, this difference in colour not being sexual.

The antenne are short, serrate from the fifth joint, and rather slender. The last joint

of the maxillary palpi is subtriangular and only moderately stout. The lines of light

pubescence on the basal half of the elytra are of a more ashy colour than the pubescence

on the posterior half, the latter being brown; the pubescence on the rest of the anterior

portion is black. The insect varies greatly in size.

MORDELLA. 285

26. Mordella rufomaculata. (Tab. XII. fig. 13.)

Rather short, black; the head broadly brown-pubescent along the middle, the sides with silvery-white

pubescence ; the prothorax with a broad median vitta, narrowing before and behind and extending com-

pletely across, and a large transverse triangular spot on either side of it behind the middle blackish-

pubescent, the rest of the pubescence silvery-white; the scutellum with white pubescence ; the elytra

with a sparsely pubescent broad fulvo-rufous lateral patch occupying the basal third, a silvery-white-

pubescent stripe extending from the base downwards (a little distant from the suture) and nearly meeting

a transverse similarly coloured median fascia (the latter not reaching the suture), the median fascia

preceded and followed and the discal stripe rather broadly bordered within with blackish pubescence,

the apical third brown-pubescent, a narrow line of similarly coloured pubescence extending up the suture

nearly to the base, the extreme apex and the scutellar region also with a little white pubescence ; the

pygidium silvery-white-pubescent, with a narrow line of brown pubescence along the middle. Palpi

testaceous, the last joint of the maxillary pair broadly triangular, its inner and outer sides subequal and

each shorter than the inner side; antenne pitchy-brown with the basal four joints testaceous, slender

and rather short, joints 3 and 4 thin, subequal, 5-11 broader but very little widened, 5-10 decreasing in

length and subserrate, 10 about as broad as long, 11 nearly twice as long as 10; elytra less than two and

a half times the length of the prothorax; beneath densely silvery-white-pubescent, the posterior coxe

behind and the first ventral segment at the apex laterally brown; pygidium moderately long and

acuminate, more than twice the length of the hypopygium; legs black, the anterior pair (the tarsi

excepted) testaceous, the intermediate femora and tibia brownish, the tibial spurs testaceous.

Length to end of the elytra 34, to tip of the pygidium 4, millim.; breadth 13 millim.

Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith).

Allied to M. chevrolati and M. seanotata, but with a very different arrangement of

the pubescence, and the sides of the elytra broadly fulvo-rufous at the base; the

antenne are also much shorter. As in the two species mentioned, the silvery-white

pubescent spots on the elytra are almost surrounded by dark pubescence, and are very

conspicuous.

27. Mordella crassipes. (Tab. XII. fig. 14.)

Moderately elongate, rather broad, black; the head, the prothorax in part, and the scutellum yellowish-

cinereous-pubescent, the prothorax with an irregular very broad blackish-brown-pubescent patch on the

disc (occupying the greater part of its width and interrupted behind on either side of the middle by a

short longitudinal extension of the light pubescence); the elytra with a broad oblique fulvous stripe ex-

tending from the shoulders to beyond the basal third and curved inwards anteriorly, this stripe, the

suture rather broadly from the base to a narrow angulated fascia at one-fourth from the apex, and the

extreme base densely yellowish-cinereous-pubescent, for the rest clothed with black pubescence ; the

pygidium yellowish-cinereous-pubescent in its basal half, black beyond. Head distinctly canaliculate

behind ; palpi pitchy-brown, the last joint of the maxillary pair elongate-triangular, its outer side not much

longer than the apical side, each very much longer than the inner side; antenne black, the five basal

joints obscure red, joints 3 and 4 short, 4 subtriangular, a little wider than 3, 5-11 moderately widened,

very strongly so, 11 a little longer but not narrower than 10; elytra moderately long; beneath black,

cinereo-pubescent, the ventral segments with a good deal of dark brown pubescence at the sides behind ;

pygidium stout, rather short, blunt at the tip, about twice the length of the hypopygium ; legs short and

stout, black, the posterior tibial spurs fusco-testaceous, the latter comparatively short.

Length to end of the elytra 4, to tip of the pygidium 5, millim. ; breadth 13 millim.

Hab. Panama, Volcan de Chiriqui (Champion).

One example only. The much shorter, stouter, and blacker legs, the differently

formed antenne, the arrangement of the elytral pubescence, &c., distinguish this species

at once from the Mexican W. triangulifer, which it perhaps most nearly resembles.

The antennal joints 5-11 are about equal in width, 3 and 4 comparatively stout. The

oblique humeral pubescent stripe partly partakes of the ground-colour from which

it arises, the rest of the surface beneath the pubescence being black.

28. Mordella rufovittata. (Tab. XII. fig. 15.)

Elongate, black, sparsely pubescent, the prothorax reddish at the sides behind, the elytra with a broad reddish

stripe at the sides extending to considerably beyond the middle and reaching the lateral margin in front ;

on the elytra traces of a yellowish-pubescent common anteapical fascia and a line of similarly coloured

pubescence extending up from it to the base are visible, the apical portion before and beyond the fascia

being blackish-pubescent (the remainder of the pubescence is abraded). Antenne testaceous, long and

thin, subfiliform, joints 3 and 4 very slender, 4 much longer than 3, 5-10 (11 is broken off) only a little

wider, all more than twice as long as broad; beneath black, the last two ventral segments reddish-

testaceous ; pygidium reddish-testaceous, the apical half a little darker, slender and moderately long,

nearly three times the length of the hypopygium; legs long and slender (the hind pair excepted),

testaceous, the posterior femora and tibise piceous, the inner posterior tibial spur exceedingly elongate.

Length to end of the elytra 34, to tip of the pygidium 4, millim.; breadth 13 millim.

Hab. Mexico, Cordova (Sallé).

Though only a single abraded, broken, specimen has been received, it is advisable to

name it, the insect differing from all the other Central-American Mordelle, M. flavi-

frons excepted, in the form of the antenne. The species is perhaps nearest allied to

M. badiipennis, from which its much more elongate shape, longer legs, and very

different colour distinguish it.

29. Mordella badiipennis. (Tab. XII. fig, 16.)

Elongate, sparsely pubescent, black, the mouth-parts (the tips of the mandibles excepted) testaceous, the pro-

thorax at the sides behind and at the base laterally reddish-brown, the elytra light reddish-brown, their

apical half indeterminately darker; the head and the prothorax at the sides in front cinereo-pubescent,

the remainder of the pubescence on the latter partaking of the ground-colour ; the elytra each with a faint

oblique yellowish-cinereous-pubescent stripe on the basal third extending from the shoulders to the suture

and a broader and more distinct similarly pubescent oblique stripe on the apical half extending from the

middle of the dise to the apex, the rest of the pubescence darker ; the pygidium cinereo-pubescent at the

base, blackish beyond. Palpi testaceous, the last joint of the maxillary pair stout, subtriangular; antenne

pitchy-testaceous with the basal four joints paler, slender, joints 3 and 4 thin, subequal, 5-11 broader but

very little widened, 5-10 feebly subserrate, gradually decreasing in length, all longer than broad (8-10

subequal), 11 stouter and a little longer than 10; elytra moderately long ; beneath silvery-white-pubescent,

black, the last ventral segments obscure testaceous ; pygidium very long and slender, compressed laterally,

pointed at the tip, more than three times the length of the hypopygium ; legs long and comparatively very

slender, in great part testaceous, the tips of the four anterior tibiee and of all the tarsal joints and the

posterior femora and the greater part of the posterior tibiz piceous.

Length to end of the elytra 3, to tip of the pygidium 44, millim.; breadth 13 millim.

Hab. GUATEMALA, Chacoj in the Polochic valley (Champion).

One specimen only, probably of the male sex. Allied to I. acuticauda, but differing

from it by the longer and more slender legs, which are in great part testaceous, the

MORDELLA. 287

reddish-brown elytra and sides of the thorax, the sparser pubescence, &c. The elytra

have a distinct broad oblique stripe of paler pubescence on the posterior half and a

faint oblique line of paler pubescence running from the shoulders downwards. The

pygidium is very long and slender, pointed at the tip. The intermediate tibie are

sinuously curved inwards. The punctuation of the upper surface is very fine and

shallow.

30. Mordella flavolineata, (Tab. XII. fig. 17.)

Moderately elongate, rather broad, black, the humeri obscure castaneous, the pygidium reddish; the head with

a line of bright golden pubescence on either side (not extending behind the eyes), for the rest brownish-

black-pubescent ; the prothorax with an oblique stripe of bright golden pubescence on either side of the

middle of the disc extending from the apex nearly to the base, and a little golden pubescence at the base

near the hind angles, for the rest blackish-pubescent ; the scutellum blackish-pubescent ; the elytra each

with a narrow interrupted slightly oblique fascia towards the sides just below the base, a narrow

transverse fascia some little distance beyond the middle (not reaching the suture), and the apex narrowly

bright golden-pubescent, for the rest clothed with blackish pubescence; the pygidium golden-pubescent to

about the middle, darker beyond. Head obsoletely canaliculate ; palpi and oral organs testaceous, the

last joint of the maxillary palpi elongate-ovate, narrow ; antenne entirely flavo-testaceous, very long,

joints 3 and 4 very slender, elongate, subequal, 5-11 moderately dilated, equal in width, all very much

longer than broad, 5-10 slightly decreasing in length, serrate, 11 elongate-ovate, scarcely longer than 10 ;

elytra moderately long; beneath black, the last two ventral segments reddish, the latter and a small spot

on the sides of the first ventral segment in front bright golden-pubescent, for the rest clothed with

brownish-black pubescence ; pygidium rather slender, comparatively short, twice the length of the hypo-

pygium; legs slender (the hind pair excepted), the two anterior pairs and the posterior tibial spurs

testaceous, the hind pair piceous but with the tarsi in great part reddish, the third and fourth joints of the

anterior and middle tarsi very feebly widened.

Var. The lines of pubescence on the head and prothorax white, those on the latter extending to the base, the

sides of the prothorax also with some whitish pubescence ; the pubescence on the scutellum and at the

base of the first ventral segment white ; the postmedian fascia of the elytra placed nearer the apex, a

little curved, and almost extending to the suture, the golden pubescence at the apex quite obsolete.

Length to end of the elytra 43-43, to tip of the pygidium 5-53, millim.; breadth 2 millim.

Hab. Mexico (Sallé); Guatemana, Senahu (Champion).

One example only from each locality, probably male and female; the Guatemalan

one is taken as the type. In the variety the lines of pubescence on the head and thorax

are white instead of golden-yellow, the markings on the elytra being of this colour in

both forms. The species is not at all closely allied to any of the other Central-American

Mordelle. In the form of the antenne it approaches J. pretosa, but it has shorter

legs and a more slender pygidium ; the antennz are entirely flavo-testaceous, long, and

have their third and fourth joints very slender; the penultimate joints of the anterior

and middle tarsi are very slightly dilated, these joints being narrow and filiform in

M. pretiosa. The typical example is figured.

31. Mordella flavofasciata. (Tab. XII. fig. 18.)

Moderately elongate, narrow, black, the mouth-parts (the tips of the mandibles excepted) testaceous ; the head,

prothorax, and pygidium sparsely clothed with yellowish-cinereous pubescence ; the elytra with a broad

fulvous-yellow transverse fascia a little below the base and a similarly coloured fascia beyond the middle

288 HETEROMERA.

(the former not nearly, the latter almost or quite, reaching the suture, the posterior one usually widening

inwardly and with its upper and lower edges concave, the anterior one sometimes extending upwards to the

shoulder), these markings golden-pubescent, the rest of the surface with dense brownish- or purplish-black

pubescence. Palpi pitchy-brown, the last joint of the maxillary pair subtriangular, moderately broad ;

antenne slender, testaceous, the outer joints sometimes darker, joints 3 and 4 short, not much longer than

broad, 4 subtriangular, slightly wider than 3, 5-11 broader than 4, longer than wide, 5-10 scarcely serrate,

subequal, 11 a little longer but not wider than 10; elytra scarcely narrower at the base than the pro-

thorax, moderately long; beneath black, the ventral segments cinereo-pubescent at the base, for the rest

clothed with dark brownish pubescence ; pygidium long and slender, considerably more than twice the

length of the hypopygium in both sexes; legs piceous, the anterior and middle knees, tibie, and tarsi

(except the tips), the hind tarsi in great part, and the base of the hind tibie and their spurs testaceous,

the anterior and intermediate tibie slightly sinuous within in the male.

Length to end of the elytra 3-32, to tip of the pygidium 4-43, millim.; breadth 13-13 millim. (¢ 92.)

Hab. Mexico, Cordova (Sallé), Teapa in Tabasco (H. H. Smith); Guarema.a, San

Gerdnimo, Capetillo (Champion).

Seven specimens. ‘This species has, unlike most of the members of the genus, the

pubescent markings of the elytra accompanied by a corresponding difference in the

ground-colour, the pubescence in fact partaking of the colour of the surface from

which it arises. The prothorax at the base is scarcely broader than the base of the

elytra. The antenne have their joints 5—11 so feebly subserrate as to be almost filiform.

M. flavofasciata cannot be confounded with any of the other species of Mordella here

described, but it seems to come near the Brazilian MZ. fulvonotata, I. quadripustulata,

and WM. decorata, Mak).

32. Mordella flavonotata. (Tab. XII. fig. 19.)

Moderately elongate, rather shining ; the head testaceous, with a piceous patch in the middle (this patch in

one specimen much extended, so that only the sides and front of the head remain testaceous), the eyes

black ; the prothorax flavo-testaceous, with a black median vitta extending from the base to the apex;

the scutellum black ; the elytra black, with two flavo-testaceous transverse fasciw—one before and the

other beyond the middle, the anterior one interrupted at the suture; the pygidium flavo-testaceous; the

pubescence sparse and partaking of the ground-colour. Head regularly convex ; palpi testaceous, the last

joint of the maxillary pair rather narrow, its apical side very much shorter than the inner or outer sides ;

antenne testaceous, slender, moderately long, joints 3 and 4 short, small, subequal, 5-11 a little widened,

longer than broad, 5 and 7 the widest; elytra convex, rather short; beneath with the metasternum

(except in the middle), the sides of the posterior coxw in front, and the sides of the first three ventral

segments black, for the rest flavo-testaceous ; pygidium exceedingly long (more than half the length of

the elytra), slender, and acuminate, more than twice the length of the hypopygium; legs flavo-testaceous,

the extreme apex of the hind tibie and of each hind tarsal joint piceous, the hind tibial spurs very

elongate.

Length to end of the elytra 23, to tip of the pygidium 34, millim.; breadth 1 millim.

Hab. Mexico, Teapa in Tabasco (H. H. Smith).

Two examples. Resembling I. flavofasciata in the elytral markings ; but differing

from it by the much longer pygidium, and by the head, thorax, and under surface

being partly yellow. The upper surface is sparsely pubescent and rather shining.

Evidently a close ally of the Brazilian MU. amena, Makl., but not altogether agreeing

with the description of that insect, MM. flaviventris, Smith, from Texas and Florida,

MORDELLA. 289

apparently comes near M. flavonotata, but is much larger (4 millim.) and also differs

in colour. MV. flaviventris is said to have a dorsal carina on the posterior tibiee and on

the first joint of the posterior tarsi; in If. flavonotata there is only the faintest trace

of a dorsal carina on the tibie.

33. Mordella nigromaculata. (Tab. XII. fig. 20.)

Moderately elongate, narrow, reddish-yellow, the eyes black, the elytra with a common scutellar spot, the

shoulders, a broad median fascia, and the apices black; the pubescence partaking of the ground-colour.

Head regularly convex ; palpi testaceous, the last joint of the maxillary pair broadly triangular, its apical

side scarcely shorter than the inner or outer sides; (antenne broken off); elytra elongate, convex, the

scutellar region somewhat depressed ; beneath entirely testaceous ; pygidium very slender and compressed,

very long and acuminate, more than twice the length of the hypopygium; legs testaceous, the extreme

apex of the hind tibie and the apex of each hind tarsal joint piceous ; hind tibie and first joint of hind

tarsi with a faint dorsal carina.

Length to end of the elytra 32, to tip of the pygidium 44, millim.; breadth 13 millim.

- Hab. Mexico, Cordova (Sal/é).

One example. Allied to M. flavonotata, but much more elongate and with a very

different system of coloration. The black median and apical fascize are formed by

rounded spots which are confluent at the suture with those on the opposite elytron.

34. Mordella lineatipyga. (Tab. XII. fig. 21.)

Elongate, narrow, cuneiform, black; the head in great part brown-pubescent, the sides narrowly white-

pubescent; the prothorax with a very broad blackish-pubescent median vitta and a narrower similarly

coloured stripe on either side of it (the former extending to the apex but not to the base, the latter not

reaching either the base or the apex), for the rest clothed with whitish pubescence which (except at the

sides) is intermixed with brown hairs; the elytra obscure testaceous at the shoulders, for the rest black,

with the following brownish-cinereous-pubescent markings—a short stripe (widened in front) on the

middle of the disc just below the base, a transverse fascia a little beyond the middle (not reaching the

suture or lateral margin), and a curved narrower fascia just before the apex, the latter connected at the

suture with a narrow stripe which extends upwards to the base and is continued along it to the shoulders,

—the pubescence on the rest of the surface (the humeri excepted) black; the pygidium whitish-

pubescent, with a blackish line along the middle. Palpi testaceous, the last joint of the maxillary pair

broadly securiform ;, antenne pitchy-brown with the basal four joints testaceous, long and slender, joints

3 and 4 about equal in length, 4 a little stouter than 3, 5-11 broader than 4, all much longer than broad,

5-10 slightly decreasing in length, feebly subserrate, 11 much longer than 10; scutellum transversely

triangular, rounded behind; elytra elongate, narrowing from the base; beneath black, densely clothed

with white pubescence, the ventral segments with alittle brown pubescence at the sides behind; pygidium

short and stout, conical, not twice the length of the hypopygium; legs moderately slender (the hind pair

excepted), the two anterior pairs in great part and the posterior tibial spurs testaceous, the hind pair

piceous, the penultimate joint of the anterior and middle tarsi feebly dilated.

Length to end of the elytra 3, to tip of the pygidium 4, millim. ; breadth 13 millim.

Hab. Panama, Bugaba (Champion).

One example. In the form of the scutellum this little species is almost intermediate

between Tomoxia interrupta and Mordella; but as the scutellum is really subtriangular

(or rather trapezoidal), the insect is best placed in Mordella. The last joint of the

maxillary palpi is broadly securiform ; the antennz long and slender. M. lineatipyga

is not at all closely allied to any other species here described. ©

85. Mordella univittata. (Tab. XII. fig. 22.) ©

Elongate, convex, black, very densely punctured ; the head, prothorax, and scutellum densely clothed with

yellowish-cinereous or golden pubescence, the prothorax with a faint median blackish-brown-pubescent

vitta and a large similarly coloured oblong spot on either side of it (the former much narrowed in front,

extending to the apex and almost: to the base, the latter placed nearer to the base than to the apex); the

elytra each with a broad oblique stripe on the disc extending from the shoulder to the apex and the suture

narrowly from the base downwards yellowish-cinereous- or golden-pubescent, for the rest clothed with

blackish-brown pubescence ; the pygidium yellowish-cinereous-pubescent to about the middle, darker

beyond. Head very convex; palpi testaceous, the last joint of the maxillary pair stout, broadly trian-

gular; antenne pitchy-brown with the two basal joints testaceous, long and slender, joints 3 and 4 thin,

subequal, 5-11 moderately widened, much longer than broad, 5-10 subserrate, almost equal in length, 5-7

rather wider than the following joints, 11 a little longer than 10 ; elytra moderately long; beneath densely

and uniformly clothed with yellowish-cinereous pubescence, without darker markings; pygidium rather

slender, elongate, pointed at the tip, more than twice the length of the hypopygium ; legs black, the anterior

and intermediate coxe, femora, and tibie (the apical half of the latter excepted), and the hind tibial spurs,

testaceous.

Length to end of the elytra 33-4, to tip of the pygidium 43-53, millim.; breadth 13-13 millim.

Hab. Mexico, Teapa in Tabasco (H. H. Smith); Panama, Bugaba (Champion).

Two examples, agreeing perfectly with each other; the one from Bugaba is a female,

the other possibly a male. In this species the head is very convex, much as in Tomoazia

interrupta and T. fulviceps. It may be recognized from the other Mordelle here

described by the broad uninterrupted oblique stripe of yellowish-cinereous pubescence

on each elytron, this stripe extending from the shoulder to the apex and there connected

with the very narrow sutural one. ‘The antenne are long and comparatively slender,

the last joint of the maxillary palpi is broadly triangular, and the pygidium is elongate

and rather narrow.

36. Mordella atricolor.

Elongate, rather broad, entirely black, the pubescence above and beneath black, the elytra in one example

with a few scattered intermixed single cinereous hairs. Labrum, mandibles, and palpi black, the last

joint of the maxillary palpi stout, triangular; antenna biack, long, joints 4-11 moderately widened, 4

much wider and longer than 3, 5 broader than 4, 6-10 obliquely subquadrate, about as broad as long, and

decreasing slightly in width, 11 longer and rather narrower than 10; prothorax with the median basal

lobe broadly rounded ; elytra comparatively long and convex; pygidium conical, moderately long, about

twice the length of the hypopygium ; legs entirely black, comparatively stout.

Length to end of the elytra 54, to tip of the pygidium 6%, millim.; breadth 23 millim.

Hab. Mexico, Hacienda de la Imagen 4000 feet, Acaguizotla 3500 feet, both in

Guerrero (H. H. Sinith).

Two examples. Exceedingly like the European WM. aculeata, Linn., but differing

from it by its larger size, stouter build, broader apical joint of the maxillary palpi, and

black mouth-parts, and also by the form of the antenne—in WV. aéricolor joints 6-10

MORDELLA. 291

are widened on the inner side from near the base and are therefore less triangular in

shape. The more elongate antenne, the stouter fourth joint, and the obliquely

quadrate shape of joints 6-10 separate WM. atricolor from M. scutellaris. So far as can

be ascertained without dissection, the outer lobe of the maxilla is short, not elongated

as it is in M. aculeata. The pubescence of the head, thorax, and elytra is uniformly

black; in one example, however, a few single scattered cinereous hairs are visible upon

the elytra.

37. Mordella pustulosa, (Tab. XII. figg. 23-25.)

Elongate, rather broad, black ; the head cinereo-pubescent; the prothorax with a broad black median vitta

(extending to the apex but not to the base) and a large rounded transverse black spot on either side of

this about the middle, for the rest yellowish-cinereous-pubescent ; the scutellum cinereo-pubescent ; the

elytra with the suture for a short distance from the base downwards, an oblique mark on the disc in a

line with the lower portion of this, curving outwards and narrowly extended to the base, a short curved

oblique stripe external to it, an oblong rounded spot close to the suture before the middle, and a rather

broad angulated fascia some distance beyond the middle (deeply excised on its anterior edge near the

suture and almost divided in the middle of the disc by a line of black pubescence extending inwards from

its posterior margin) golden-pubescent, the rest of the pubescence black; the pygidium cinereo-pubescent

towards the base, black beyond. Head convex, obsoletely canaliculate ; the last joint of the maxillary

palpi piceous, broad and securiform in both sexes; antenne black, sometimes reddish towards the base,

moderately long in both sexes, joint 3 slender, 4-11 wider, much longer than broad, 4-10 serrate, 5-7

more strongly so; elytra narrowing from the base, moderately long, flattened on the disc, declivous

laterally, with rather prominent shoulders ; beneath with the pubescence in great part cinereous; pygidium

moderately long, somewhat obtuse at the tip, especially in the female, one and a third or one and a half

times as long as the hypopygium, a little shorter in the female; legs black, the hind tibial spurs (and the

anterior femora in part) testaceous; the anterior tibie a little curved and the anterior femora ciliate

within in the male.

Var, a. The postmedian fascia divided into two spots on each elytron (placed obliquely, one before the other) ;

the anterior femora entirely testaceous.

Var. 3. The sutural patch abbreviated, the oblique mark on the disc at the base divided into two spots (placed

one below the other), the curved oblique stripe external to it lower down extending to beyond the middle

of the elytra and broken up into a series of spots, and the postmedian fascia much narrower than in the

type, not reaching to the suture and deeply excised on its lower edge. (Fig. 24.)

Var. y. As in B, but with the oblique stripe below the shoulders much abbreviated or almost obsolete (some-

times represented by a short transverse mark), and the postmedian fascia reduced to a narrow transverse

lunate mark or small spot on each elytron. (Fig. 25.)

Length to end of the elytra 44-7, to tip of the pygidium 63-84, millim.; breadth 24-3 millim. (¢ 9.)

_ Hab. Nicaracua, Chontales (Belt); Panama, Bugaba, Volcan de Chiriqui (Champion).

Nine examples. The description is chiefly taken from a large well-marked example

from Chontales; of the var. « we have only one specimen, from Chiriqui; of the var. 3

one female only, from Chontales ; and of the var. y six specimens, one from Chontales

and the rest from Chiriqui. The insect varies very much in size, and also in the form of

the postmedian fascia—in the var. y it being reduced to a small lunate mark or puncti-

form spot. In the var. @ the oblique line of spots on the outer portion of the disc is

not symmetrical with that on the opposite elytron. The anterior femora in one example

are entirely testaceous. The thorax is similarly marked in all the forms. The much

smaller size, shorter and more pointed pygidium, very different elytral markings, &c.

distinguish the species from WZ. signata. The antenne have their joints 4-10 serrate,

5-7 more strongly so; the penultimate joints are in both sexes about twice as long as

broad. In UM. signata the fourth antennal joint is very little wider than the third.

The tibial spurs are testaceous. The light pubescence varies in colour from ashy-

white to golden.

38. Mordella septemnotata. (Tab. XII. fig. 26.)

Elongate, moderately broad, black ; the head with a very narrow line of cinereous pubescence along the base

and also with some cinereous pubescence i in front, the rest of the pubescence black ; the prothorax some-

what broadly margined on all sides with cinereous pubescence, the rest of the pubescence black ; the

scutellum cinereo-pubescent ; the elytra densely clothed with whitish-cinereous pubescence, a large rounded

transverse spot on either side of the suture close to the base, a short elongate stripe external to it reaching

the base, a broad median fascia, narrowing inwardly and not quite reaching the suture, and the apical

third black ; the pygidium cinereo-pubescent at the extreme base, for the rest black. Palpi black, the last

joint of the maxillary pair stout, subtriangular (2); antenne black, moderately stout, joints 4-11

widened, 4 very much longer and wider than 3 but narrower than 5, 5-9 rather longer than broad, 10

about as broad as long; elytra moderately long, gradually narrowing from the base, flattened on the

disc, with rather prominent humeral callus; the underside in great part black, the ventral segments

at the base and the side-pieces of the metasternum with a little cinereous pubescence; pygidium ( 9 )

short, rather obtuse at the tip, about twice the length of the hypopygium; legs black, the tibial

spurs lighter.

Length to end of the elytra 64, to tip of the pygidium 74, millim.; breadth 23 millim. ( 9.)

Hab. Mexico, Acaguizotla in Guerrero (H. H. Smith).

One female example. Allied to MW. mexicana; the black pubescence much more

extended, occupying by far the greater portion of the head and thorax (the sides only

of the latter being cinereous), the elytra with an elongate additional mark at the

shoulders, a much broader apical patch (which is not narrowed towards the suture in

front), the median fascia more widened outwardly, and the basal spot much larger and

placed more in front; the legs and antenne are stouter, entirely black, the antenne

considerably shorter.

39. Mordella mexicana. (Tab. XII. fig. 27.)

Elongate, moderately broad, black, cinereo-pubescent ; the prothorax with a small rounded, oblique black spot

on either side of the middle of the disc; the elytra with a small rounded spot on either side of the suture

near the base, a rather broad median fascia, not extending to the suture and widening a little externally,

and the apex broadly (but more narrowly so towards the suture in front) black ; the pygidium and entire

under surface cinereo-pubescent. Head obsoletely canaliculate behind.’ Palpi testaceous, the last joint

of. the maxillary pair darker, the latter stout, subtriangular; antenne pitchy-brown with the basal four

joints testaceous, rather slender, joint 3 narrow, 4-11 wider, much longer than broad, 4—10 serrate, 5-7

more strongly so; elytra moderately long, gradually narrowing from the base, flattened on the disc, with

rather prominent. humeral callus; pygidium moderately long, obtuse at the tip, nearly twice the length of

the hypopygium ; legs black, the anterior femora flavo-testaceous, the tibial spurs testaceous; the anterior

tibiz a little curved, and the anterior femora fringed with long hairs within, in the male.

Length to end of the elytra 5, to tip of the pygidium 6, millim.; breadth 24 millim. (¢.)

Hab. Mexico, San Andres Tuxtla (Sallé).

One male example. In the form of the antenne and. pygidium this insect resembles

MORDELLA. 293

M. pustulosa, and in the elytral markings M. septemnotata ; the cinereous pubescence

on the thorax and elytra, however, occupies a much larger portion of the surface than

it does in M. septemnotata. The black apical fascia is partly interrupted in front,

owing to the cinereous pubescence being extended a short distance downwards along

the suture. The antenne are longer and more slender than in I. septemnotata, and

have the basal joints testaceous.

40. Mordella cata.

Moderately elongate, black; the head, prothorax, and scutellum yellowish-cinereous-pubescent, the prothorax

with an ill-defined black median vitta (not reaching the base or apex) and a large oblong black patch on

either side of it; the elytra obscure castaneous at the shoulders, with an oblique stripe extending from

the humeri towards the suture, a small spot below it on the lateral margin, an oblique spot extending

outwards from the suture a little below the middle, the suture very narrowly from this spot to the base,

and the base itself, narrowly, yellowish-cinereous-pubescent, for the rest clothed with black pubescence ;

the pygidium blackish-pubescent. Palpi testaceous, the last joint of the maxillary pair a little darker at

the tip, very broadly triangular, its apical and outer sides about equal in length, each a little longer than

the inner side; antenne testaceous with the apical four joints pitchy-brown, long and rather slender, joint

3 short, as long as but more slender than 2, 4~11 moderately widened, much longer than broad, 4 nearly

twice as long as and very much broader than 3, 5-7 the widest, 11 oblong-ovate, the width and length

of 10; elytra moderately long, rather convex ; beneath cinereo-pubescent, the ventral segments cinereo-

pubescent at the base only, for the rest clothed with dark brownish pubescence ; pygidium long and

rather slender, broad at the base, not quite twice the length of the hypopygium; the intermediate and

posterior tibiee and tarsi in great part and the anterior legs entirely testaceous, the four hinder femora

piceous.

Length to end of the elytra 44, to tip of the pygidium 53, millim.; breadth 13 millim.

Hab. Mexico, Cordova (Sallé).

One example, probably a male. Somewhat resembling J/. arcwata in the arrange-

ment of the cinereous pubescence of the elytra (in M. arcuata, however, the suture is

not cinereo-pubescent); but much smaller than that insect, the apical joint of the

maxillary palpi broadly triangular, the antenne more filiform and with the fourth joint

stouter, the pygidium more slender and almost pointed, and the post-median fascia of the

elytra reduced to an oblique mark on either side of the suture. The yellowish-cinereous-

pubescent markings on the basal portion of each elytron almost enclose a large blackish-

pubescent spot.

41. Mordella leucogramma. (Tab. XIII. fig. 1, 2.)

Elongate, rather narrow, black ; the head cinereo-pubescent ; the prothorax with a black median vitta (slightly

widened behind and not quite reaching the base or apex) and a very large black triangular patch on either

side of it, the rest of the pubescence cinereous ; the scutellum cinereo-pubescent; the elytra each with an

oblique curved stripe extending from the shoulders downwards towards the suture and widened behind

into a rather large patch (so as to partly enclose a large black basal spot), a curved oblique stripe below this

externally (more or less divided into two spots—one on the disc and one some distance below the shoulder),

a rather broad fascia beyond the middle (excised on its lower edge, curving a little downwards towards

the suture, and sometimes not reaching the suture or lateral margin), and the base behind the scutellum

einereo- or whitish-pubescent, the rest of the pubescence black ; the pygidium cinereo-pubescent to about

the middle, black beyond. Palpi testaceous, the last joint of the maxillary pair darker, the latter very

large, stout, and subequilaterally triangular in the male, smaller and subcultriform in the female; antenne

294 HETEROMERA.

black with the basal four or five joints testaceous, rather long, joint 3 slender, 4-11 moderately widened,

longer than broad, 4 triangular, a little narrower than 5, 5-10 subserrate ; elytra moderately long; beneath

cinereo-pubescent, the ventral segments black at the apex; pygidium rather short and slender, acuminate,

shorter in the female, not quite twice the length of the hypopygium ; legs black, the anterior femora and

tibiz more or less and the posterior tibial spurs testaceous.

Length to end of the elytra 3-33, to tip of the pygidium 37-47, millim.; breadth 1j-13 millim. (¢ 9.)

Hab. Guatemaua, Capetillo, Duefias (Champion).

Three examples. As in J. biformis and WM. leucosticta, the last joint of the maxil-

lary palpi in the male is much stouter than in the female. In the slender pygidium

&c. M. leucogramma comes very near MV. leucosticta, but differs from that species in

having the fourth joint of the antenne triangular and much wider than the third ;

the oblique stripe extending from the shoulder downwards is shorter and bent more

abruptly inwards behind, and this is followed externally by a second oblique stripe

or two oblong spots, of which there is no trace in M/. leucosticta. The more slender

pygidium, the broader fourth joint of the antenne, and the testaceous tibial spurs

distinguish it from MW. albopicta, M. tetraspilota, &c. In two of the specimens the

second oblique stripe is represented by two oblong (or small) rather widely separated

spots—one on the disc and one below the shoulder-stripe ; these marks are not always

symmetrical, and in two examples they are differently formed on one elytron to what

they are on the other.

42. Mordella cingulata. (Tab. XIII. figg. 2,¢; 2a, maxillary palpus.)

Elongate, rather narrow, black; the head, prothorax, and scutellum brownish-cinereous-pubescent, the pubes-

cence on the disc of the prothorax indeterminately darker; the elytra each with a broad patch in front

(occupying the basal third, narrowing on the disc behind, and extending a little downwards at the

sides), enclosing a large black basal spot, and a narrow fascia just beyond the middle (not quite reaching

the suture or lateral margin, and curving downwards towards the suture) brownish-cinereous-pubescent ;

the pygidium clothed with black pubescence, cinereous only at the extreme base. Palpi testaceous, the

last joint of the maxillary pair a little darker, the latter stout and securiform. Antenne (d) black with

the basal three joints and the basal half of the fourth testaceous, rather long, joint 3 slender, very short,

4-11 moderately dilated, much longer than broad, 4 triangular, more than twice as long and fully twice as

wide as 3, very little smaller than 5, 4—8 distinctly serrate, 9 and 10 slightly narrower and more parallel ;

elytra moderately long ; beneath in great part cinereo-pubescent; pygidium rather slender, long and

acuminate, about twice the length of the hypopygium; legs black, the anterior and intermediate femora

testaceous, the tibize of the same pairs of legs pitchy-brown, the tibial spurs testaceous; the anterior

tibiee ( ¢ ) distinctly curved.

Length to end of the elytra 33, to tip of the pygidium 4, millim.; breadth 13 millim. (¢.)

Hab. Panama, Caldera in Chiriqui (Champion).

One male example. Closely resembling M. leucosticta, but differing from it by the

triangularly dilated fourth joint of the antenne, the third joint also being shorter ;

the light pubescence is of a fusco-cinereous colour and is more extended on the basal

portion of the elytra, completely enclosing a large black basal spot; the post-median

fascia is placed a little more forwards and is curved downwards towards the suture. In

the form of the antenne the species resembles I. pustulosa.

43. Mordella biformis. (Tab. XIII. figg. 3,3; 3a, antenna, 30, maxillary

palpus, ¢; 4,2; 4a, maxillary palpus, ? .)

dg. Elongate, rather narrow, black ; the mentum and mouth-parts (the tips of the mandibles excepted) testa-

ceous ; the head cinereo-pubescent; the prothorax rather broadly bordered on all sides with cinereous

pubescence, which in one or two examples extends upwards on either side of the middle to the anterior

margin so as to enclose three large oblong ill-defined spots, the rest of the surface sparsely clothed with

blackish pubescence ; the scutellum cinereo-pubescent; the elytra each with two short stripes (often

confluent) placed parallel to each other near the suture some distance before the middle—the external

one curving outwards, extending forwards to the base and continued along it to meet a triangular scutellar

patch (nearly or quite enclosing a large oblique black spot), and more or less coalescent with an oblique

post-humeral stripe,—and a long comma- or c-like mark on the dise beyond the middle cinereo-pubescent,

the rest of the pubescence black; the pygidium cinereo-pubescent at the base, black beyond. Palpi

testaceous, the apical joint of the maxillary pair infuscate, the latter very stout, securiform, and thickly

eeneous lustre, the venter piceous, the last two segments a little paler, the pubescence in part cinereous, in

- part black ; pygidium rather slender, long and acuminate, compressed at the sides, nearly twice as long as

the hypopygium ; legs piceous or black, the anterior femora in great part and the coxe flavous, the inter-

mediate femora (except at the apex), and sometimes the base of the anterior tibis reddish-testaceous, the

Hab. Murxico, Cerro de Plumas, Oaxaca (Hage), Cordova, Tehuantepec (Sallé), Teapa

(H. H. Smith); Britisn Honpuras (Blancaneauax) ; GuateMALA, Cahabon, Chiacam, San

Juan, and San Gerénimo in Vera Paz, Zapote (Champion), Coban and Panzos (Conradt).

This is one of the commonest species of Mordella in Southern Mexico and Guate-

mala, whence we have obtained a large number of examples. The sexes, both of which

have been obtained in most of the above localities, differ considerably in the colour of

the thorax and in that of the terminal segments of the body, as well as in the shape

and clothing of the apical joint of the maxillary palpi. The cinereo-pubescent markings

of the elytra are sometimes reduced a little in size, sometimes much more extended ;

the comma-like mark on each elytron beyond the middle is always distinct. The

thorax usually has the base, apex, and sides cinereo-pubescent, the rest of the surface

being only very sparsely pubescent. In the rufous thorax, terminal ventral segments,

and pygidium the female closely resembles the corresponding sex of the following

species. The sexes of the European Mordellistena abdominalis (Fabr.) differ from each

other in colour in a somewhat similar way. The N.-American I. oculata, Say (= jovi-

alis, Lec.), seems to be an ally of MW. biformis.

44, Mordella rutilicollis. (Tab. XIII. fig. 5, 2 .)

Q. Elongate, cuneiform, moderately broad, black, the labrum and mouth-parts (the tips of the mandibles

excepted) testaceous ; the head cinereo-pubescent, the pubescence sometimes golden-brown in colour on

either side of the middle; the prothorax rufous, with the lateral margins and base, narrowly or somewhat

broadly, infuscate or black, the sides, base, and apex bordered with cinereous pubescence, the rest of the

surface much more sparsely clothed with darker pubescence; the scutellum cinereo-pubescent; the

elytra each with an elongate-subtriangular mark on the disc some distance before the middle, con-

nected anteriorly at its outer extremity with a short stripe which extends along the base to the suture

(nearly enclosing a large oblique black spot), an oblique stripe some distance below the shoulders, a

narrow transverse fascia beyond the middle (not reaching the suture or lateral margin), and the suture

very narrowly from the base nearly to the apex cinereo-pubescent, the rest of the pubescence entirely

black ; the pygidium, except at the tip, rufous, cinereo-pubescent. Head obsoletely canaliculate behind ;

the palpi testaceous, the last joint of the maxillary pair infuscate, the latter stout, subtriangular ; antenne

black with the three or four basal joints testaceous, long, rather slender, joint 3 narrow, 4-11 wider,

much longer than broad, 4—7 subtriangular, 8-11 more parallel and slightly narrower ; elytra moderately

long; beneath black, the last two ventral segments, and sometimes the third in the middle, rufous, the

pubescence in great part cinereous; pygidium moderately long, blunt at the tip, about twice the length

of the hypopygium ; legs black, the anterior femora and the base of the anterior tibie sometimes fusco-

testaceous, the tibial spurs testaceous.

Length to end of the elytra 4-64, to tip of the pygidium 5-83, millim.; breadth 13—2% millim.

Hab. Guatemata, Capetillo (Champion).

Four examples, apparently all females. Closely allied to MW. diformis, but differing

from the female of that species by having the suture of the elytra narrowly cinereous,

the long comma-like mark beyond the middle replaced by a transverse fascia, the two

parallel stripes near the suture before the middle replaced by an elongate-triangular

spot, and the pygidium shorter and more obtuse at the tip. None of the examples of

either sex of I. biformis show the slightest trace of a cinereous line along the suture

nor of the comma-like mark being replaced by a transverse fascia. It is not improbable

that the male of MV. rutilicollis has the thorax and the terminal segments of the body

black. The markings of the elytra approach those of MW. insulata, Lec. (figured by

J. B. Smith, Trans. Am. Ent. Soc. x. t. 2. fig. 5).

45. Mordella erythrocephala. (Tab. XIII. fig. 6.)

Elongate, rather narrow; the head entirely rufous, the prothorax black, with the base and sides rather broadly

flavo-testaceous, the scutellum black, the elytra black, each with a flavo-testaceous discoidal stripe exten-

ding from the base nearly to the apex (wide at the base and narrow beyond), the pygidium reddish-testa-

ceous ; the pubescence in great part partaking of the ground-colour. Head regularly convex; palpi

obscure testaceous, the last joint of the maxillary pair piceous, the latter subtriangular, its inner and

outer sides about equal in length, each very much longer than the apical side; antenne long and rather

stout, black, the three basal joints a little paler, joints 4-11 moderately widened, longer than broad, 4

much longer and wider than 3 but narrower than 5, 7-10 decreasing in width, 11 as long as but much

narrower than 10; elytra convex, nearly four times as long as the prothorax; beneath broadly black at

the sides, for the rest flavo-testaceous, cinereo-pubescent ; pygidium very slender and compressed, long,

and acuminate, more than twice the length of the hypopygium ; legs rather slender, the anterior and

intermediate femora entirely, the basal two-thirds of the hind femora, the anterior and intermediate tibise

in their basal half, the base of the hind tibizw and their spurs, and the hind tarsi in great part testa-

ceous, for the rest piceous, the penultimate joint of the four anterior tarsi somewhat broadly dilated,

the inner spur of the hind tibise exceedingly elongate.

convex, a little more than three times as long as the prothorax; beneath with the metasternum (except

in the middle) and the sides of the ventral segments 1-4 black, for the rest flavous ; pygidium very slender

and compressed, moderately long ; legs entirely flavo-testaceous ; hind tibie with traces of a faint dorsal

carina.

Length to end of the elytra 3, to tip of the pygidium 33, millim.; breadth 1 millim.

Hab. Mexico, Teapa in Tabasco (H. H. Smith).

One specimen. Near WW. erythrocephala, but differing by its less elongate shape, the

much more slender antenne, and the longer and narrower apical joint of the maxillary

palpi, as well as in colour. The discoidal vitta on each elytron is broader and placed

nearer the suture than in UW. erythrocephala. ‘The posterior cox are entirely flavous,

as well as the ventral segments in the middle and the centre of the metasternum.

47. Mordella flavifrons. (Tab. XIII. fig. 8.)

Short, broad, thickly and uniformly clothed with cinereous or yellowish-cinereous pubescence, the pubescence

paler on the light-coloured parts and a little more obscure on the dark parts but not forming spots or

markings ; the head reddish- or flavo-testaceous, with the vertex black, the black colour sometimes more

extended and reaching to the occiput, the eyes also black ; the prothorax more or less reddish or reddish-

testaceous on either side of the middle anteriorly, this colour sometimes more extended so as to leave

only a broad median vitta and a large patch on either side of the base laterally black or piceous; the

scutellum and elytra black, the apex of the latter narrowly testaceous or yellow; the pygidium reddish-

testaceous, darker towards the tip. Palpi testaceous, the last joint of the maxillary pair very broad and

a little longer than 10; elytra short, not two and a half times the length of the prothorax ; beneath,

the prothorax excepted, black, the ventral segments at the apex or in great part reddish-testaceous,

densely and finely punctured, each ventral segment with a row of coarse punctures on the hind margin

extending completely across, each of these punctures bearing a long coarse golden hair, the rest of the

under surface cinereo-pubescent ; pygidium moderately long, rather slender, very little shorter in the

female, more than twice the length of the hypopygium ; legs comparatively slender, the two anterior pairs

of the tarsal joints excepted) piceous, the tibial spurs testaceous; penultimate joint of the anterior and

middle tarsi produced into a Jong broad lobe beneath the apical joint and extending to two-thirds of its

298 HETEROMERA.

Four specimens only of this curious species were obtained, all from the low hot

Pacific coast-region. ‘The form of the penultimate joint of the four anterior tarsi,

together with the very slender antenne, almost uniform pubescence, &c., distinguish it at

once from all the other Mordell@ here described. Viewed from above the penultimate

joint appears to be strongly bilobed, the lobes extending to two-thirds the length of the

apical joint and connected beneath by a membranous piece which is slightly emarginate

at the apex. In addition to the usual pubescence, each of the ventral segments has a

fringe of much coarser hairs on its hind margin, these hairs arising from a line of

coarse punctures.

48. Mordella seriata, (Tab. XIII. figg. 9; 9 a, antenna.)

Moderately elongate, rather broad, pitchy-brown; the head with a broad band of dark brown pubescence

along the middle, the sides with yellowish-cinereous pubescence; the prothorax with small yellowish-

cinereous-pubescent spots scattered over the greater part of the surface, these becoming partly coalescent

on the anterior portion, a large oblong patch on the middle of the disc behind and a small one at the

apex free from spots, the rest of the surface with dark brown pubescence; the elytra with the following

yellowish-cinereous markings—a small spot at the base close to the shoulders, a larger spot near the

suture a little below the base, one opposite to it on the lateral margin, one lower down on the outer

portion of the disc midway between these, a narrow angulated fascia at one-third from the apex (not

reaching the suture or lateral margin), and numerous serially-arranged small punctiform spots (a row on

either side of the suture the most distinct), these latter extending from the base to the apex,—the rest of

the pubescence dark brown; the pygidium yellowish-white-pubescent, with a dark brown stripe along the

middle. Head with a very distinct median groove ; palpi piceous, the last joint of the maxillary pair oblong

ovate, narrow; antenne rather long, joints 3-5 very slender, 4 and 5 subequal, each a little shorter than 3,

6-11 broadly widened and forming a long club, 6-10 strongly serrate, 6 triangular, about as broad as long,

short and stout, blunt at the tip, barely twice the length of the hypopygium ; legs slender (the hind pair

excepted), pitchy-black, the two anterior pairs paler, the tibial spurs testaceous, the penultimate joint of

the anterior and intermediate tarsi filiform, the intermediate tibie and tarsi about equal in length.

Length to end of the elytra 4, to tip of the pygidium 43, millim.; breadth 13 millim.

Hab. Panama, Bugaba (Champion).

One specimen only. In the markings of the upper surface extremely like W/. sticti-

coptera (the Chacoj example of which agrees almost exactly with it); but differing

totally from that species in the form of the fifth antennal joint—very slender and

scarcely wider than the fourth in J. seriata, broadly triangularly widened and fully

three times as wide as the fourth in W. sticticoptera. At first sight WZ. seriata would

appear to be only the other sex of M. sticticoptera; the difference, however, in the

form of the antenne is too great to be sexual.

This is one of a little group of species characterized by the oblong ovate apical joint

of the maxillary palpi, the very short blunt pygidium, the simple penultimate joint of

the four anterior tarsi, and the more or less dilated antenne, the latter with the apical

or intermediate joints yellow. .

and equidistant from each other (the first transverse, the two others punctiform and smaller), two minute

spots placed obliquely at the side near the anterior one, and a small spot at the side opposite the third, and

two transverse marks placed in a line transversely just before the apex (these latter forming with the marks

on the opposite elytron a common narrow interrupted fascia),—the extreme apex also edged with golden

pubescence, the rest of the pubescence blackish-brown with a few intermixed golden hairs; the pygidium

with yellowish-white pubescence at the sides, blackish-brown along the middle. Head with traces of an

Panama, Volcan de Chiriqui (Champion).

One example only from each locality ; these evidently include the two sexes, one of

the specimens being much narrower than the others. The elytral markings vary

slightly, the serially-arranged spots being larger and showing a tendency to coalesce in

one example. In the peculiar coloration of the antennal joints this species somewhat

resembles M. varicornis, the latter, however, has the apical joint yellow; the elytral

markings are also somewhat similar, but in MW. sticticoptera the fasciee and larger spots

are much reduced in size or partly obsolete.

One example. Allied to M. xanthosticta and M. sticticoptera, but differing from both

these species in having the antenne considerably longer, more gradually and less

broadly dilated (joints 5-7 relatively much narrower), and with the joints 8-10 only

black, the eleventh being yellow; it is also larger and more elongate, and the golden

pubescence on the elytra is differently arranged, the pubescence forming two fascie near

the apex and two patches on the disc, between which are numerous small spots, these ©

spots arranged in a line on either side of the suture.

markings at the base (enclosing an oblique spot on either side of the suture), some longitudinal markings

at the side below these, a strongly angulated fascia at one-third from the apex, and an angulated

fascia between this and the apex (both reaching the suture) yellowish-cinereous-pubescent, for the rest

clothed with blackish pubescence (this forming a common large subquadrate patch before the middle and

numerous spots); the pygidium cinereo-pubescent to the middle, blackish beyond. Palpi testaceous, the

One specimen. This little species is allied to M. tenuipes, from which it differs in

its much shorter, serrate antenne (the apical joint being yellow,,not piceous), much

shorter legs, and shorter elytra; the elytral pubescence is also differently arranged.

The antenne are slender, though joints 5-10 are very distinctly serrate.

54. Mordella T-album. (Tab. XIII. fig. 15.)

Elongate, the head (except in the centre) and oral organs testaceous, the eyes, an indistinct spot on the middle

of the vertex, the prothorax, elytra, and pygidium black; the head cinereo-pubescent ; the prothorax

with a broad black median vitta and a large oblong oblique black spot on either side of it (these markings

not reaching the base or apex), for the rest clothed with white pubescence; the scutellum white-pubes-

cent; the elytra each with a long T-shaped white-pubescent mark on the middle of the disc just before

the middle and a similarly-pubescent rather broad curved fascia a little before the apex, the latter coalescing

with the mark on the opposite elytron at the suture and extending narrowly along it to the middle, the

suture also narrowly bordered with white pubescence at the base; the pygidium white-pubescent at the

sides, brown along the middle. Last joint of the maxillary palpi moderately stout, elongate-triangular,

its outer side much longer than the inner or apical sides, the latter shorter than the inner side; antenne

slender, pitchy-brown, the five. basal joints testaceous, joints 3 and 4 thin, 3 short, not longer than 2, 4

prothorax ; beneath black, thickly clothed with white pubescence; pygidium very long, moderately stout,

nearly twice the length of the hypopygium, the latter unusually elongate ; legs comparatively very slender

(the hind pair excepted), the anterior and middle pairs (the middle tarsi excepted) testaceous, the hind

pair (the tibial spurs excepted) black, the penultimate joint of the anterior and middle tarsi filiform, the

intermediate tarsi considerably longer than the tibie of the same pair of legs, the anterior and intermediate

tibiz sinuous within.

Length to end of the elytra 3, to tip of the pygidium 4, millim.; breadth 14 millim.

Hab. Guatemaa, Chacoj in the Polochic valley (Champion).

One specimen only of this peculiar little species was obtained, evidently a male. It

differs in many respects from all the other Central-American forms: the last joint of

the maxillary palpi is unusually elongate; the intermediate tarsi are considerably longer

than the tibie of the same pair of legs; the penultimate joint of the four anterior tarsi

is filiform, not in the least dilated, and formed as in the type of the genus Tomowia.

55. Mordella pretiosa. (Tab. XIII. fig. 16.)

Moderately elongate, broad, black or brownish-black, the sides of the prothorax and the elytral humeri obscure

castaneous ; the head with a broad band of dark brown pubescence along the middle, the sides with

yellowish-cinereous pubescence; the prothorax with a reversed cruciform brownish-black-pubescent mark

on the middle of the disc (not quite reaching the base or apex, narrowing anteriorly, and interrupted in

front by a line of the lighter pubescence), connected at the sides in front with a similarly-coloured oblique

subtriangular patch, the rest of the surface densely and uniformly clothed with yellowish-cinereous pubes-

cence; the elytra with the following yellowish-cinereous markings—a common transverse band at the base

(enclosing one or two spots on each elytron), from which a broad branch runs a little way downward on the

middle of the disc, a short interrupted stripe external to this posteriorly, an angulated fascia at about one

third from the apex, a narrow straight fascia immediately before the apex (both very nearly extending to

the lateral and sutural margins), and numerous scattered almost serially arranged punctiform spots,—the

rest of the pubescence brownish-black; the pygidium yellowish-cinereous-pubescent, with a dark brown

stripe along the middle. Head obsoletely canaliculate ; palpi testaceous, the last joint of the maxillary

pair slender, elongate-ovate, its apex obliquely truncate; antennz long, testaceous, the apical one or two

joints piceous, joints 3 and 4 very elongate and slender, subequal, 5-11 moderately widened, all very

much longer than broad, 5-10 serrate, gradually decreasing in length, 5 longer than 4, 11 elongate-ovate,

longer than 10; elytra moderately long; beneath densely yellowish-cinereous-pubescent, the posterior

coxee and the ventral segments at the sides behind with some dark brown pubescence; pygidium stout,

rather short, blunt at the tip, not twice the length of the hypopygium ; legs very long and slender (the

hind pair excepted), the hind pair black with the tibial spurs testaceous, the two other pairs in great part

testaceous, the penultimate joint of the anterior and intermediate tarsi filiform, the intermediate tarsi

slightly longer than the tibiz of the same pair of legs.

Length to end of the elytra 5, to tip of pygidium 6, millim.; breadth 24 millim.

Hab. Mexico, Cordova (Saillé).

Two examples, agreeing perfectly with each other, their sex not ascertained. At once

separable from M. varicornis, M. sticticoptera, &c., by the more slender antenne (joints

MORDELLA. 303

5-11 equal in width), longer legs, longer pygidium, and different thoracic and elytral

markings. The peculiarly shaped dark markings on the centre of the thorax are very

sharply defined from the dense pale pubescence ; the elytra have, as in M. varicornis

&c., numerous punctiform subserially arranged spots in addition to the larger markings,

these latter being more extended on the basal portion than they are in MV. sticticoptera

and WW. seriata. The legs are very elongate, especially the intermediate pair.

56. Mordella tenuipes. (Tab. XIII. fig. 17.)

Moderately elongate, rather broad, brownish-black; the head and prothorax clothed with yellowish-cinereous

pubescence, the latter with a broad median brownish-black-pubescent vitta and an oblique similarly-

coloured stripe on either side of it (the former narrowing anteriorly and interrupted in front by a trans-

verse line of light pubescence, the two latter widening posteriorly, these markings not quite extending to

the base or apex); the scutellum brownish-black-pubescent; the elytra with numerous small yellowish-

cinereous-pubescent spots scattered all over the surface, these spots coalescing here and there and at one

third from the apex forming a rather broad irregular fascia and at the base laterally a short stripe, the

rest of the pubescence brownish-black; the pygidium yellowish-cinereous-pubescent at the base, brown

towards the tip. Palpi testaceous, the last joint of the maxillary pair darker, the latter slender, oblong-

ovate; antenne long and very slender, thickening a little outwardly, obscure testaceous, the apical four

joints piceous, joints 3 and 4 very elongate and thin, subequal, 5 considerably longer than 4, widening

outwardly, 6—10 slightly wider, about equal in width but gradually decreasing in length, all much longer

than broad and scarcely subserrate, 1] stouter and one half longer than 10; elytra moderately long;

beneath blackish-brown, the venter paler, yellowish-cinereous-pubescent ; pygidium short and stout, almost

‘pointed at the tip, not twice the length of the hypopygium ; legs long and slender (the hind pair excepted),

in great part obscure testaceous, the hind femora piceous, the anterior and intermediate tibiee and tarsi

very long and thin, the intermediate tarsi distinctly longer than the tibiee of the same pair of legs, the

penultimate joint of the four anterior tarsi filiform.

Length to end of the elytra 3, to tip of the pygidium 4, millim.; breadth 14 millim.

Hab. Panama, Volcan de Chiriqui (Champion).

One example only. MV. tenuipes is not at all closely allied to any of the other species

here described, but (though much smaller) perhaps comes nearest to M/. pretiosa. The

four anterior legs are exceedingly slender and elongate; the antenne are subfiliform,

long, and very slender, but a little thickened outwardly; the apical joint of the maxil-

lary palpi is quite slender, oblong ovate in shape; the pygidium is short and stout,

but pointed at the tip. The antenne, legs, and palpi are still more slender than in

M. pretiosa; the elytra (but not the head and thorax) are marked somewhat as in

that species. —

57. Mordella tantilla.

Short, cuneiform, black, the mouth-parts (the tips of the mandibles excepted) testaceous, above and beneath

uniformly clothed with brownish-cinereous pubescence. Last joint of the maxillary palpi piceous, stout,

subtriangular, its apical and inner sides about equal in length, and both much shorter than the outer side ;

antenne piceous with the basal four joints testaceous, very short, joints 3 and 4 narrow, equal in length, 5-

11 alittle widened, 5-10 serrate, decreasing in length but increasing in width, 9 and 10 transverse, 11 a little

longer than 10, blunt at the tip; elytra short, convex; pygidium very long and almost pointed, more than

twice the length of the hypopygium ; legs (the hind pair excepted) long and slender, black, the anterior

femora and tibie testaceous, the penultimate joint of the anterior and middle tarsi filiform, the inter-

mediate tibie shorter than the tarsi of the same pair of legs, the posterior tibial spurs obscure testaceous,

the inner spur very elongate.

Length to end of the elytra 24, to tip of the pygidium 34, millim.; breadth 1 millim.

Hab, Guatemana, Sinanja in Vera Paz (Champion).

One example only. Much smaller than the smallest examples of MW. scutellaris or

M. melena; the anterior and middle pairs of legs more slender and with their

penultimate tarsal joint filiform; the intermediate tarsi a little longer than the tibize

of the same pair of legs; the pygidium more slender, much more elongate, and almost

pointed. The last joint of the maxillary palpi is comparatively stout, as stout as in

M. melena; the antenne are very short and slender, the joints from the fifth serrate

and a little widened. A mutilated example from Bugaba perhaps belongs to the

same species.

58. Mordella fenestrata. (Tab. XIII. figg. 18,3; 18a, maxillary palpus )

Elongate, narrowly cuneiform, black, the head narrowly (and abruptly) in front and the labrum testaceous, the

prothorax with a small fulvous spot at the sides, the elytra each with an oblong subtriangular sordid

yellow patch on the dise below the base and a much smaller and more obscure spot beyond the middle

(the anterior spot deeply concave in front); the basal and apical margins of the prothorax narrowly

cinereo-pubescent, the pubescence on the rest of the surface partaking of the ground-colour, sparse, and

not altogether hiding the punctuation. Head exceedingly convex, the eyes pubescent ; palpi testaceous,

the last joint of the maxillary pair ( ¢ ) piceous, subquadrangular, more than twice as broad as long, deeply

excavate on its apical side, and abruptly truncate at the tip ; antennee with the basal four joints testaceous,

the others in great part piceous, long and rather slender, joint 3 short and narrow, 4-11 moderately

widened, longer than broad, 4~7 the widest and more distinctly serrate than 8-10, 11 fully one and a

half times as long as 10; prothorax transverse, very convex, the base deeply bisinuate; elytra convex,

narrower than the prothorax, and gradually narrowing from the base; pygidium very long and acuminate,

moderately stout, nearly twice the length of the hypopygium ; beneath with a little cinereous pubescence

at the sides of the ventral segments in front, for the rest blackish-pubescent ; legs moderately stout, black,

the anterior femora and tibie and the middle femora (partly) testaceous, the tibial spurs flavous; the

penultimate joint of the four anterior tarsi dilated and excavate; intermediate tibiee and tarsi equal in

length; the inner spur of the posterior tibie very elongate.

Length to end of the elytra 33, to tip of the pygidium 4, millim. ; breadth (prothorax) 1 millim. (<¢.)

Hab. Panama, Taboga Island (Champion). —

One example. Differs from all the preceding in the form of the last joint of the

maxillary palpi in the male. This joint has its apical and lower sides straight and

parallel to each other, and is abruptly truncate at the tip; it is articulated at its

lower external angle to the third joint. The head is exceedingly convex. The pubes-

cence is sparse, and does not hide the punctuation. MM. fenestrata has much the facies

of the European genus Stenalia, Muls. It may have eventually to be separated from

the genus Mordella; but as Mordellistena also contains species with somewhat similarly

formed palpi in the male, it is not advisable to separate it. The hind tibie are without

oblique ridges on their outer face, the subapical one excepted.

GLIPODES. 305

GLIPODES.

Glipodes, Leconte, Proc. Acad. Phil. xiv. p. 47 (1862)’; J. B. Smith, Trans. Am. Ent. Soc. x. p. 84

(1882).

Leconte ! states that ‘the species of this genus are cuneiform, narrow, fuscous, and

covered with a dense sericeous brown pubescence. The scutellum is rounded-trian-

gular; the anal style is moderately long; the hind tibie have no subapical ridge

(which exists in all the other genera), but are carinate along the dorsal line, and

furnished with a long oblique ridge on the outer surface, which is connected with the

dorsal ridge near the tip; the first joint of the hind tarsi has two oblique ridges. The

eyes are coarsely granulated; the antenne are feebly serrate. The last joint of the

maxillary palpi is scalene-triangular in form, and in the male of G. sericans is covered

on the under surface with a dense brush of short fine hair; in the same sex there is at

the base of the last joint an external articulated bifurcated appendage, the branches of

which are as long as the joint; no vestige of this is seen in the female ; the last joint

of the labial palpi of both sexes of G. sericans is triangular and broadly emarginate at

tip; in G. helva the same joint is bell-shaped and truncate at tip.” In the single

Central-American Glipodes, which I refer without hesitation to G. sericans (Melsh.),

the first, second, and third joints of the hind tarsi have each a single oblique ridge

extending to about half the length of the joint (there being no trace of a second ridge

on the first joint *), the intermediate tibie are (as in Glipa) longer than the tarsi of the

same pair of legs, and have each a single long spur, and the penultimate joint of the

anterior and middle tarsi is dilated and excavate. The middle tibiz are conspicuously

longer than the tarsi of the same pair of legs, a character overlooked by Leconte and

also by J. B. Smith.

Of this very widely distributed species we have obtained nine examples from Central

spurs are testaceous, the inner spur nearly twice as long as the outer one. The third

and fourth joints of the antenne are slender, the fourth longer than the third and much

narrower than the fifth.

CONALIA.

Conalia, Mulsant, Ann. Sc. Nat. Lyon, 1858, p. 313; Opusc. Ent. ix. p. 55; Emery, Essai

Monogr. sur les Mordellides, in L’Abeille, xiv. p. 73 (1876).

The chief characters given by Mulsant for this genus are :—“ Tibias postérieurs sans

dent sur leur aréte dorsale; rayés sur leur face externe d’une hachure ou d’une ligne,

naissant de leur angle postéro-externe et longitudinalement avancée au moins jusqu’a

la moitié de la longueur des dits tibias, en sécartant graduellement un peu du bord

externe.” This description was taken from a mutilated example (without hind tarsi),

from Hungary, and the insect named C. baudii. A Central-American species merely

differs from the above definition in having the single oblique ridge on the outer

face of the hind tibie extending to fully three-fourths of their length. In the

American insect the first and second joints of the hind tarsi have each a similar ridge

to that on the tibie; the hind tibie (as in Glipodes) are without a short subapical

ridge, and also without a dorsal carina (this being conspicuous in Glipodes); the

labial palpi are long and slender, their apical joint very elongate and subacuminate ;

the lobes of the maxilla are moderately long, the outer lobe only a very little longer

and stouter than the inner one; the last joint of the maxillary palpi is moderately

stout, and subcultriform in both sexes; the eyes are finely granulated ; the intermediate

tibia and tarsi are equal in length; the penultimate joint of the four anterior tarsi is

very feebly dilated and excavate ; the inner spur of the hind tibiz is very long, more.

than twice the length of the outer one; the last dorsal segment or pygidium is very

shert (much shorter than in C. daudii, Muls., and only a little longer than in Cothurus),

broadly conical, very little longer than the hypopygium, and, owing to the curvature

of the abdomen, not visible beyond the apex of the elytra.

1. Conalia ebenina. (Tab. XIII. figg. 20; 20a, labium; 208, maxilla and

maxillary palpus; 20, hind leg.)

Moderately elongate, subparallel, black or brownish-black, uniformly clothed with dark brown pubescence.

Head regularly. convex, very narrowly extended on either side behind the eyes; palpi pitchy-black ;

antenne black with the basal joints a little lighter, short, joints 3 and 4 slender, 5-11 moderately dilated,

5-10 subserrate, 5 very much broader than 4, the penultimate joints moderately transverse in the male,

strongly so in the female, 11 a little longer than 10; prothorax transverse, deeply bisinuate at the base,

the median lobe broadly produced and subtruncate behind, the sides sinuate behind the middle (parallel

posteriorly if viewed from above) ; elytra very little narrower than the prothorax, convex, moderately long ;

beneath with a little cinereous pubescence at the base of the first ventral segment and on the meta-

sternum, for the rest clothed with dark brown pubescence ; pygidium exceedingly short and obtuse,

scarcely longer than the hypopygium, not visible from above; legs black, the four anterior femora some-

times a little lighter, the posterior tibial spurs piceous.

CALYCE.

Head rather broadly extended behind the eyes and at the sides angularly projecting beyond them; the eyes

rounded, comparatively small, coarsely granulated; (palpi missing); antennz with joints 5-10 very

broadly dilated and strongly transverse ; prothorax short, strongly transverse, with a broad median lobe

in front and behind, the basal lobe produced far beyond the hind angles, the latter obtuse; scutellum

subtriangular; elytra long, parallel for three-fourths of their length; pygidium very short, broadly

conical, very little longer than the hypopygium; the penultimate joint of the four anterior tarsi very

feebly dilated and excavate; the intermediate tibiz and tarsi equal in length; the hind tibie and first

joint of the hind tarsi with oblique ridges on their outer face, the middle tibie with a single long spur ;

body broad, parallel, rather depressed.

This genus is proposed for a species from the State of Panama*. In the shape

of the head, thorax, and pygidium, as well as in general facies, it differs greatly from

Mordellistena, to which, however, it is very closely allied. ‘The palpi and the apical

joint of the antenne are unfortunately broken off in the single example obtained.

The pygidium is shorter than in any species of Mordellistena.

1. Calyce fulva. (Tab. XIII. figg. 21; 21 a, antenna.)

Elongate, above and beneath fulvous, thickly clothed with rather coarse similarly-coloured pubescence. Head

very broad, somewhat flattened in the centre, and with a short median groove in front, the tips of the

mandibles and the eyes black ; antennez rather short, joints 1-3 testaceous, 4 slightly infuscate, 5-10

black (11 missing), 3 and 4 short, 4 much wider than 3, transverse, 5-10 very broadly widened, equal in

width ; prothorax strongly transverse, broad, rounded at the sides behind, the hind angles obtuse, the

median basal lobe rounded and much produced; elytra a little narrower than the prothorax, rather

depressed on the disc, long and parallel ; legs fulvo-testaceous ; the hind tibiz with five (including the

subapical one), the first joint of the hind tarsi with three (the first rudimentary), short, oblique, parallel

ridges ; the middle tibiee with a single rather long spur ; wings black.

southwards, the converse being the case in the genus Mordella. Mexico and Central

America prove to have almost the same number of species as the United States:

seventy-five in the former, as against seventy-seven in the latter. Of the seventy-five

here enumerated, forty-one occur in Mexico, thirty-four in Guatemala, and sixteen in

the State of Panama. Very few species extend from Mexico to Panama, but many

are common to Mexico and Guatemala; a considerable number seem to be peculiar to

Western Mexico. Twenty-three species only have been recorded as yet from South

America——one from Colombia, four from Peru, sixteen from Brazil, and two from

Chili; but several of the species of Mordella of the older authors belong to it, as

M. ferruginea, Fabr., from §. America, M. rubida, Er., from Peru, &c. One species

only has hitherto been described from within our limits. Important sexual characters

are to be found in many species of Mordellistena, more particularly in the form of the

apical joint of the maxillary palpi. In I. ephippiata, M. lineatocollis, and M. equi-

noctialis, and also in some very small species, M. xanthopyga, M. palpalis, M. perexigua,

&c., this joint is hammer- (or boat-) shaped in the male, and more or less elongate-

triangular or oblong-ovate in the female: J. ephippiata and its allies agree very nearly

with the European J. abdominalis, Fabr., a species placed by Emery in his section

Mordellochroa, though he did not notice the form of the maxillary palpi in the male;

M. xanthopyga, &c., with the species placed by the same author in his section Tolida.

The apical joint of the maxillary palpi is often a little longer in the male than in the

female, in some cases being stouter and more angular, and in others more cultriform,

in the first-ementioned sex; the second joint in several species is considerably stouter

in the male than in the female. In the males of WM. distorta and M. curvimana the

anterior tibiee are broadly dilated and flattened, and the first joint of the anterior tarsi

is bowed inwards and much elongated. In the male of I. sexmaculata the eight outer

joints of the antenne are thickened and much elongated, the fourth and fifth being

equal; in the female of the same species the fourth joint is small and subequal with

the third, the fifth being more than twice as long as, and very much stouter than,

the fourth. ‘The number and position of the ridges on the hind tibiz and on one

or more of the hind tarsal joints is also a very useful character in discriminating the

numerous species; but American authors have placed far too much reliance upon the

exact number of these ridges. Amongst a long series of examples of some species an

additional, often short or rudimentary, ridge (or two) is to be found in advance of the

others on the tibie or tarsal joints of one or more specimens, the additional ridge (or

ridges) not always being symmetrical on both legs; in M. murina &c. the ridges vary

in number from 3-5 on the tibie and first tarsal joint. In a number of species (as in

many from the United States) the anterior ridge on the hind tibie is obliquely extended

across their outer face to near the base, this character easily distinguishing several very

closely allied forms. In two Mexican species undoubtedly belonging to this genus,

M. fasciculata and M. festiva, the hind tibie have only a subapical ridge (as in

MORDELLISTENA. 309

Mordella) ; but rudimentary or subobsolete ridges are present on some of the hind

tarsal joints.

In J. B. Smith’s monograph of the North-American species (Trans. Am. Ent. Soc. x.

pp. 85-98), and in that of Leconte (Proc. Acad. Phil. xiv. pp. 48-50), the form of the

antennee and palpi is not even noticed in the descriptions; the first-mentioned author

states (doc. cit. p. 85) that “there appear to be no external sexual peculiarities.”

The subapical ridge of the hind tibie is counted with the others in the following

descriptions.

The annexed table will assist in the identification of the Central-American species ;

palpus.)

Moderately elongate, robust, cuneiform, fulvous; the eyes and the tips of the mandibles black; the palpi

testaceous ; the elytra with a common broad fascia just beyond the middle (extending upwards along

the epipleure towards the base, and partly divided at the suture behind) and the scutellar region, inde-

terminately, piceous ; the pubescence dense and partaking of the ground-colour. Head slightly depressed

in the middle behind, the eyes rather small; last joint of the maxillary palpi (¢) exceedingly large,

than 10; prothorax transverse, the base with a few dark hairs in the middle; elytra convex, moderately

long, narrower than the prothorax ; pygidium long and rather slender, more than twice the length of the

hypopygium; beneath entirely fulvous; legs moderately stout, reddish-testaceous, the ridges on the

hind pair black; the hind tibie with three oblique ridges (the first and second very long, the third

shorter and subapical) ; the first joint of the hind tarsi with three, the second and third joints each with

two, oblique ridges.

Length to end of the elytra 4, to tip of the pygidium 5, millim.; breadth 14 millim. (<.)

Hab. GuateMaa, Zapote (Champion).

One male example. Easily distinguished from all the other Central-American

species by the broadly fasciate elytra and fulvous colour, and by the exceedingly large,

curved, hammer-shaped apical joint of the maxillary palpi in the male sex. The head,

MORDELLISTENA. 311

when viewed in certain lights, has an opalescent lustre. The middle tibie are without

spurs, but they may be broken off.

2. Mordellistena lineatocollis. (Tab. XIII. figg. 23,9; 23a, antenna, 9;

23 6, maxillary palpus, 2; 24, maxillary palpus, 3.)

Elongate, robust, cuneiform ; the head rufous, with a large broad black patch in the middle behind, and with

coppery and violaceous reflections in certain lights; the prothorax fulvous, with a black median vitta

extending from the base to the apex, but narrowing in front; the scutellum piceous; the elytra black

(violaceous when the pubescence is removed); the pygidium obscure reddish-yellow, infuscate at the

tip ; the pubescence dense, on the elytra and on the median vitta of the prothorax black, and on the head

and scutellum yellowish-cinereous, that on the rest of the prothorax and on the pygidium partaking of the

ground-colour. Head slightly depressed in the middle behind; the eyes black; palpi piceous, the last

joint of the maxillary pair differing greatly in shape in the two sexes—(¢) about three times as broad

as long, a little curved, and somewhat hammer-shaped, the apical and inner sides almost parallel, the tip

obliquely truncate, the apical side deeply excavate within—( ?) stout, scalene-triangular; antenne

black, the two basal joints obscurely rufous in one specimen, moderately stout in the male, very stout in

the female, joints 3 and 4 short, 3 narrow, 4 subtriangular, wider than 3, about as broad as long, 5 nearly

twice as long and twice as broad as 4, 5-10 gradually decreasing in width, but equal in length, all longer

than broad, 11 oblong-ovate, longer than 10; prothorax much broader than long; elytra convex, elongate,

narrowing from the base ; beneath with the head, the prothorax, the posterior coxe in the middle, and

the last ventral segment reddish-yellow, for the rest black, the pubescence along the middle of the venter

and at the sides of the segments in front yellowish-cinereous, for the rest partaking in great part of the

ground-colour; pygidium very long, rather slender, more than twice the length of the hypopygium ; legs

piceous, the hind pair lighter in colour, the four anterior femora obscure testaceous, the tibial spurs

testaceous ; the hind tibie with three long oblique ridges and a shorter subapical one; the first joint of

the hind tarsi with three, the second and third joints each with two, long oblique ridges; the middle

Hab. GuatemaLa, Panima and San Juan in Vera Paz (Champion).

Two specimens only. Somewhat allied to the European M. abdominalis, Fabr.; but

similar in colour in the two sexes, and with the antenne very differently formed.

These organs, as in MW. wquinoctialis, are stouter in the female than in the male, and

the fifth joint is the stoutest in both sexes. When denuded of the black pubescence,

the elytra and the median vitta of the thorax are metallic violaceous. The first of the

three long ridges on the hind tibie might be almost described as a dorsal carina, it

being placed almost on the outer edge of the tibia.

3. Mordellistena gequinoctialis. (Tab. XIII. figg. 25, ¢; 25a, antenna, 25 8,

maxillary palpus, 25 ¢, hind leg, ¢; 26, antenna, 26a, maxillary palpus, 9 .)

Elongate, rather broad, robust, subparallel, the female more cuneiform ; varying in colour from obscure cas-

taneous to blackish-brown ; the prothorax in both sexes usually reddish or obscure testaceous, with a large

oblong blackish patch on the middle of the disc, and a smaller patch on either side towards the lateral

margin—these markings sometimes connected and more or less surrounding a transverse patch of the

ground-colour on each side of the base; the pygidium reddish or obscure castaneous ; the pubescence

dense, in great part partaking of the ground-colour, but often more or less golden-brown on the apical

fourth of the elytra (in rare examples the apical patch is extended a short distance up the suture, or an

ill-defined broad oblique stripe extending from the shoulders inwards is golden-brown-pubescent). Head

regularly convex, the eyes very large; palpi testaceous, with the last joint of the maxillary pair darker,

the latter differing greatly in shape in the two sexes—() nearly three times as broad as long, a little

curved, and somewhat hammer-shaped, the apical and inner sides almost parallel, the tip obliquely

truncate, the apical side deeply excavate within—( 9 ) elongate-triangular, with the angles rounded, the

inner side not very much shorter than the outer side, the apical side only about half the length of the

latter ; antenne varying in colour from testaceous to piceous with the two basal joints paler—(d)

moderately stout, joints 3 and 4 short, 3 narrow, subtriangular, 4 wider than 3, fully as broad as long, 5

very much broader than and more than twice as long as 4, 6 narrower and a little shorter than 5, 6—10

gradually decreasing in width, about equal in length, all considerably longer than broad, 11 elongate-ovate,

longer than 10—( 2 ) shorter, much stouter, and more tapering, joints 5-10 rapidly decreasing in width,

5 very thick, 6 and 7 as broad as long, 8-10 rather longer than broad, 11 a little longer than 10; pro-

thorax much broader than long; elytra elongate, convex, more parallel in the male than in the female;

beneath (the prothorax excepted) usually in great part piceous, with the apex of each ventral segment

reddish ; pygidium rather slender, very long in the male, shorter in the female, in the male nearly two

and a half times, in the female twice, the length of the hypopygium; legs piceous or brownish, with the

four anterior femora usually, and the tibial spurs, testaceous; the hind tibiz with two long oblique ridges

and a shorter subapical one, and a long faint subdorsal ridge towards the base; the first joint of the hind

tarsi with three, the second and third joints each with two, long oblique ridges; the middle tibize with a

single long fine spur.

Length to end of the elytra 4-54, to tip of the pygidium 5-64, millim.; breadth 13-13 millim. (¢ 9.)

Hab. GuateMata, Capetillo, Teleman, Senahu (Champion) ; Panama, Bugaba, Volcan

de Chiriqui (Champion).

Numerous examples of both sexes. ‘This is one of a little group of closely-allied

Central-American species. It has the fifth joint of the antenne very stout, and the

fourth short in both sexes, these organs themselves being much thicker and more

tapering in the temale than in the male. The last joint of the maxillary palpi in the

male is formed as in UY. lineatocollis; but this joint in the female is more elongate,

and not so broad as in that insect, with the angles more rounded. ‘The median patch on

the disc of the thorax is distinct in all the specimens, but in two examples the lateral

marks are obsolete. ‘The pubescence on the apical fourth of the elytra is usually

golden-brown. The hind tibiz have in addition to the three well-marked oblique ridges

a long fine ridge near the base (only visible when the tibia is detached or viewed in a

particular way), this latter being less distinct than in J/. léneatocollis.

4. Mordellistena valens. (Tab. XIII. fig. 27, 2 .)

Elongate, broad, robust, cuneiform ; the head castaneous or reddish-yellow, darker in front, the eyes black,

the prothorax luteous, the scutellum and elytra pitchy-brown, the elytra paler at the base and beyond

the middle, the pygidium reddish; the elytra with nearly the apical half, an interrupted fascia before

the middle (formed by oblique lines of pubescence), and some lines at the base golden-brown-pubescent,.

the pubescence on the rest of the elytra blackish-brown, that on the prothorax and scutellum partaking

of the ground-colour. Head regularly convex; palpi (Q) testaceous or pitchy-brown, the last joint of

tie maxillary pair elongate, moderately stout, scalene-triangular, with the angles somewhat rounded ;

antenne (@) similar in colour to the palpi, moderately stout, subfiliform, joints 3 and 4 small, rather

longer than broad, 4 a little wider than 3, 5 about twice as long and twice as wide as 4, 5-10 decreasing

in width, all considerably longer than broad, 11 slightly longer than 10; elytra elongate, narrowing

almost from the base; pygidium (Q) very long and pointed, more than twice the length of the hypo-

pygium ; beneath with the metasternum, the posterior cox, and the base of each ventral segment piceous,

for the rest reddish ; legs testaceous or reddish testaceous, the dorsal edge of the hind tibi and tarsi piceous ;

hind tibize and tarsi with the ridges as in MV, equinoctialis ; the middle tibie with a single long fine spur.

Length to end of the elytra 5, to tip of the pygidium 6, millim.; breadth 12 millim. (9.)

Hab. Panama, Bugaba (Champion).

‘Two female examples. Very close to M. wquinoctialis, from the corresponding sex

of which it differs as follows :—The antenne are longer, more slender, and less tapering

(resembling those of the male of that species), and have their joints 5-10 all consider-

ably longer than broad ; the last joint of the maxillary palpi is wider and more angular ;

the thorax is luteous ; the elytra have an interrupted antemedian fascia, as well as more

than the apical third, golden-brown-pubescent ; the pygidium is longer (as long as in the

male of MZ. equinoctialis); and the body is stouter, broader, and more cuneiform.

5. Mordellistena castaneicolor. (‘lab. XIV. figg. 1, @; 1a, maxillary

palpus. )

Elongate, robust, cuneiform, castaneous, clothed with golden-brown-pubescence, the eyes and the tips of the

mandibles black. Head regularly convex, the eyes very large; maxillary palpi ( 2 ) testaceous, the apical

joint castaneous, the latter elongate, rather stout, scalene-triangular ; antenne ( 2 ) testaceous, compara-

tively slender, joints 3 and 4 narrow, longer than broad, subequal, 5-10 moderately widened, subserrate,

about equal in length but slightly decreasing in width, all considerably longer than broad, 5 very much

longer than 4, 5 and 6 almost equal, 11 longer than 10; prothorax transverse; elytra long and convex,

gradually narrowing from the base; beneath castaneous, the breast slightly darker; pygidium conical,

moderately long, twice the length of the hypopygium; legs testaceous, the dorsal edge of the hind pair

piceous ; the hind tibie with two long oblique ridges and a shorter subapical one, anda long fine sub-

dorsal ridge towards the base; the first joint of the hind tarsi with three, the second and third joints

each with two, long oblique ridges ; the middle tibia with a single long fine spur.

‘Length to end of the elytra 53, to tip of the pygidium 6, millim.; breadth 12 millim. ( 9.)

Hab. Panama, David in Chiriqui (Champion).

One female example. Allied to WM. equinoctialis and WM. valens, but with the

antenne much more slender, and the apical joint of the maxillary palpi stouter than

in the females of these species; the antennal joints 5-10 are subserrate, and the fifth

and sixth are almost equal (the fifth scarcely stouter than the sixth); the pygidium is

shorter than in the females of WM. valens. The apical joint of the maxillary palpi is

almost as stout as in M/. lineatocollis ( ¢ ), but it is more elongate. The pubescence is

uniformly golden-brown. ‘The eyes are very large.

6. Mordellistena verzpacis. |

Elongate, robust, cuneiform, castaneous, clothed with golden-brown-pubescence, the eyes and the tips of the

mandibles black. Head regularly convex ; maxillary palpi ( Q ) obscure testaceous, the apical joint piceous,

the latter short and stout, broadly triangular, its apical and inner sides about equal in length, both much

shorter than the outer side; antenne (@) piceous with the two basal joints testaceous, moderately stout,

short, joints 3 and 4 short, 3 narrow, 4 as broad as long, 5 very much wider than and nearly twice as long

as 4, 5-10 slightly decreasing in width, all about as broad as long, 11 longer than 10; prothorax, elytra,

pygidium, and legs as in M. castaneicolor ; beneath castaneous, the posterior coxee and metasternum piceous.

Length to end of the elytra 4, to tip of the pygidium 5, millim.; breadth 13 millim. (@.)

314 ; HETEROMERA.

Hab. Guatemata, Teleman (Champion).

One female example from the Polochic valley. Exceedingly like the same sex of

M. castaneicolor, and only separable therefrom by the very different form of the palpi

and antenne. In the shape of the antenne the present insect approaches JM. wqui-

noctialis (2 ), from which it may be at once distinguished by the much shorter and

broadly triangular shape of the apical joint of the maxillary palpi. The fifth antennal

joint, as in I. wquinoctialis, &c., is distinctly stouter than the sixth ; in M. verwpacis

joints 5-10 are much shorter and stouter than they are in MV. castanetcolor(2). A

single specimen from San Juan, Vera Paz, is perhaps a small male of the same species ;

it has the pygidium much longer, and each elytron marked with an arcuate indistinct

dark brown fascia about the middle; the antenne are unfortunately broken off.

7. Mordellistena vafer.

Elongate, robust, cuneiform ; the head piceous in front, obscure castaneous behind, the labrum testaceous, the

prothorax castaneous, with the disc largely suffused with piceous, the elytra blackish-brown, with the

shoulders indeterminately castaneous, the pygidium piceous, reddish at the base and tip ; the sides of the

prothorax and of the elytra and the suture with a little golden-brown pubescence, the pubescence on the

rest of the surface partaking of the ground-colour. Head regularly convex; palpi ( 2 ) testaceous, the

last joint of the maxillary pair infuscate, the latter rather stout, elongate-triangular, with the angles

rounded ; antenne (@ ) pitchy-brown with the two basal joints testaceous, moderately stout, subfiliform,

joints 3 and 4 small, equal in length, longer than broad, 4 wider than 3, 5 nearly twice as long as and much

broader than 4, 5-10 subequal, longer than broad, 6 not quite so stout as 5, 11 a little longer than 10;

prothorax transverse ; elytra elongate, gradually narrowing from the base ; beneath castaneous, the breast

piceous ; pygidium moderately long and comparatively stout, twice the length of the hypopygium, blunt

at the tip; legs testaceous, the hind pair reddish with the dorsal edge black; the hind tibie with two

long very oblique ridges and a shorter subapical one, and a faint subdorsal ridge towards the base; the

first joint of the hind tarsi with three, the second and third joints each with two, long, oblique ridges.

Length to end of the elytra 4, to tip of the pygidium 43, millim.; breadth 13 millim. ( 2.)

Hab. Panama, Tolé (Champion).

One female example. Very similar to IZ. equinoctialis (2); but with the last joint

of the maxillary palpi stouter, the antenne more slender and subfiliform, the pygidium

stouter and less pointed at the tip, and the suture narrowly golden-brown-pubescent.

The last joint of the maxillary palpi is more ovate in shape than in the same sex of

M. valens, M. castaneicolor, or M. verepacis; the antennz are almost as slender as in

M. castaneicolor ( 2 ), but joints 5-11 are not so elongate. In the form of the antenne

the insect is most closely allied to MW. valens.

8. Mordellistena bicarinata.

Moderately elongate, cuneiform, ferruginous or flavo-ferruginous, the elytra a little darker, the pubescence

uniform and partaking of the ground-colour. Palpi testaceous or fusco-testaceous, the last joint of the

maxillary pair elongate, scalene-triangular ; antenne testaceous, or fusco-testaceous with the basal four

joints paler, filiform, slender, moderately long, joint 3 thin, 4 longer and stouter than 3, 5-10 elongate,

about equal in length, 5 a little longer and stouter than 4; prothorax transverse; elytra gradually

narrowing from the base; beneath coloured as above; pygidium very long and slender, two and a half

MORDELLISTENA., 315

times the length of the hypopygium; legs testaceous, the hind pair a little darker ; the hind tibise with

two rather long, very oblique, ridges and a short subapical one: the first joint of the hind tarsi with three,

the second and third joints each with two, short, oblique ridges.

Length to end of the elytra 3-33, to tip of the pygidium 32-42, millim.; breadth 1-1} millim.

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

‘Two examples, probably male and female, one of them having the antenne shorter

and more slender, and the fourth joint a little shorter, than in the other. Less elongate

than M. gracilicornis, the pygidium longer and more slender, the hind tibie with two

long, very oblique, ridges and a short subapical one (instead of five short parallel ones).

The shorter, broader, and more cuneiform shape, &c., distinguish it from the other

similarly-coloured Mordellistene here described.

9, Mordellistena callens.

Rather short and robust, cuneiform, black or pitchy-brown, the mouth-parts testaceous; the pubescence

sericeous-brown, uniform. Head large, very broad; maxillary palpi pitchy-brown or obscure testaceous,

stout, the last joint broad-ovate with the apex very obliquely truncate; antenne pitchy-brown with

the basal joints paler, rather short, joints 3 and 4 narrow, subequal, 5-11 moderately thickened, 5-10

subequal, a little longer than broad, 5 much longer and stouter than 4, 11 longer than 10; prothorax

transverse; elytra rather short, narrowing from the base; beneath black, the apical margins of the

ventral segments obscure testaceous ; pygidium long and moderately stout, more than twice the length

ot the hypopygium ; legs testaceous or brownish, the hind pair darker ; the hind tibize with three oblique

ridges—the first and second long, extending partly across the outer face of the tibia, parallel, equal, the

third (subapical) short ; the first joint of the hind tarsi with three, the second and third joints each with

two, oblique, parallel ridges.

Length to end of the elytra 3-33, to tip of the pygidium 33-43, millim.; breadth 1-1} millim.

Hab. Mexico, Vera Cruz (Sallé), Atoyac in Vera Cruz (H. H. Smith); Guatema.a,

Senahu (Champion) ; Nicaracua, Chontales (Janson).

Five examples, apparently including both sexes. From J. valens and its allies this

species may be known by its less elongate shape and much smaller size, and by the

first and second carine of the hind tibie being extended partly across their outer face

(instead of being placed one behind the other just below the dorsal edge). From

M. instabilis, var. n, the position and number of the carine on the hind tibiz (two of

these being elongated in WY. callens) sufficiently distinguish it; the third hind tarsal

joint of the former is without carine.

10. Mordellistena isthmica. (Tab. XIV. fig. 2.)

Comparatively short, cuneiform, black, the mouth-parts testaceous, the elytra with an oblique rather broad

flavo-testaceous stripe extending from the shoulders almost to the middle and a longitudinal obscure

testaceous stripe extending from a little below this to the apex (these markings forming an interrupted

dorsal stripe on each elytron), the pygidium black, obscurely reddish towards the apex ; the pubescence

yellowish-cinereous on the elytral markings, for the rest blackish, that on the prothorax and head partly

cinereous. Head broad, short; palpi testaceous, the last joint of the maxillary pair darker, the latter

not very stout, elongate-ovate, with the apex abruptly truncate, the apical side very much shorter than

the inner side ; antenne rather short, obscure testaceous, with the basal joints paler, joints 3 and 4 short,

narrow, subequal, 5-11 moderately thickened, 5-10 gradually decreasing in length and width, subserrate,

not much longer than broad, 5 nearly twice as long as, and very much wider than, 4; prothorax trans-

verse ; elytra rather short, gradually narrowing from the base; beneath black, the middle of the breast

and the apex of each ventral segment testaceous; pygidium comparatively short, rather stout, conical,

twice the length of the hypopygium ; legs testaceous, the hind pair a little darker; the hind tibize with

three oblique parallel ridges—the first extending more than halfway across the outer face of the tibia,

the third short; the first joint of the hind tarsi with three or four, and the second and third joints each

with two, oblique ridges. .

Length to end of the elytra 24-3}, to tip of the pygidium 34-4, millim.; breadth g-13 millim. (@.)

Hab. Panama, San Lorenzo, Tolé (Champion).

Two examples. This species resembles the typical form of MW. mutabilis in its

elytral markings, but it is shorter and broader, and has a more transverse head and

thorax, and 2 much shorter and stouter pygidium; the ridges on the hind legs extend

on to the third tarsal joint; the last joint of the maxillary palpi is stouter, more

abruptly truncate at the apex. In the larger example there is an additional (finer)

ridge in front of the others on the dorsal edge of the hind tibie.

11. Mordellistena sexmaculata. (Tab. XIV. figg. 3,¢; 3a, antenna, 6;

4, 2, var.; 4a, antenna, 2.)

Moderately elongate, robust, cuneiform ; the head and prothorax flavo- or reddish-testaceous, the former (when

viewed laterally or from behind) with a more or less brilliant opalescent lustre, the eyes black, the pro-

thorax with indications of a very faint oblong median patch and a large spot on either side of it, the

median patch in one example piceous (violaceous in certain lights); the scutellum and elytra piceous, or

black with a violaceous lustre, the elytra each with a large oblique patch just below the shoulders extend-

ing inwards, but not nearly reaching the suture, a broad transverse fascia or rounded spot at the middle,

and a similar mark immediately before the apex (neither of which quite reach the suture) flavo-testaceous ;

the pygidium flavous or reddish to about the middle, darker beyond; the pubescence on the dark parts of

the elytra black, for the rest partaking of the ground-colour. Head convex ; palpi testaceous or flavous,

the last joint of the maxillary pair moderately long, scalene-triangular, with the angles somewhat rounded,

similar in both sexes; antenne piceous or pitchy-brown, with the four basal joints testaceous, very

differently formed in the two sexes—( ¢ ) filiform, exceedingly elongate, fully as long as the elytra, joint

3 slender, about as broad as long, 4-11 very elongate, gradually increasing in length and decreasing in

width, the penultimate joints about two and a half times as long as broad, 11 longer than 10—(? ) one

third shorter, joints 3 and 4 slender, 4 slightly wider and only a little longer than 3, 5-11 almost equal in

length, 5 very much longer and wider than 4, the penultimate joints twice as long as bread ; prothorax

transverse; elytra moderately long, gradually narrowing behind; beneath entirely flavo-testaceous, or

testaceous with the sides of the metasternum, posterior coxe, and ventral segments, to a greater or less

extent, piceous; pygidium slender and very elongate in both sexes, two and a half times the length of

the hypopygium ; legs testaceous, the dorsal edge of the hind pair darker; the hind tibie with five

(including the subapical one), the first joint of the hind tarsi with four, and the second and third joints

each with two (those on the third very faint), short, oblique, parallel ridges.

Length to end of the elytra 3j-4, to tip of the pygidium 43-5, millim.; breadth 1-14 millim. (do 2.)

Hab. Mexico, Atoyac in Vera Cruz (//. H. Smith); Guatmmata, Chacoj and Panima

in Vera Paz (Champion).

Three examples from Mexico (two females and one male), and two (both females)

from Guatemala, all from the lower part of the Atlantic slope. The antenne are very

elongate in the male, and their fourth and fifth joints are differently shaped in the two -

MORDELLISTEN A. 37

sexes. The palpi and pygidium are similarly formed in the male and female. The

Guatemalan specimens have their under surface darker in colour than those from

Mexico, and one of them has a well-defined dark vitta on the disc of the thorax ; these

examples also have the opalescent. lustre on the head much more distinct. The ground-

colour of the elytra is apparently dull piceous or black, but when the pubescence is

removed the surface is shining and has a metallic violaceous lustre. I. hexastigma is

very similar in colour, but it has differently formed palpi and antennz and a shorter

pygidium.

12. Mordellistena crassipyga. (Tab. XIV. fige. 5; 5a, antenna; 54, hind

leg.)

Elongate, robust, rather broad, cuneiform, black; the head, the prothorax in front and at the base, the

scutellum, the elytra with the extreme base, a large oblique postmedian spot on the disc, the suture very

narrowly to about the middle, and the apices, yellowish-cinereous-pubescent, the rest of the pubescence

on the elytra purplish-black, and that on the prothorax brown. Head moderately convex ; palpi reddish-

testaceous, the last joint of the maxillary pair darker, the latter elongate, scalene-triangular, its outer

side straight ; antenne long and filiform, pitchy-black with the four basal joints reddish-testaceous,

joint 3 slender, 4-11 thickened, almost equal in width but slightly decreasing in length, 4 about twice

the length and nearly twice the width of 3, the penultimate joints twice as long as broad; prothorax

transverse ; elytra long, gradually narrowing from the base; beneath black, the sides of the breast and

the extreme base of the first and second ventral segments with some yellowish-cinereous pubescence ;

pygidium stout, broad at the base, conical, short, twice the length of the hypopygium; legs piceous, the

anterior femora and the anterior and intermediate tibie partly testaceous, the hind tibial spurs testaceous ;

the hind tibiee with six (including the subapical one), the first joint of the hind tarsi with five, and the

second joint with two, short, oblique, parallel ridges.

Length to end of the elytra 43, to tip of the pygidium 5, millim.; breadth 14 millim.

Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith).

One example. Very close to M. forticornis, of which I at first supposed it to be

the female. In the females of the allied I. sewmaculata (which has similarly formed

antenn in the male) the fourth antennal joint is short and very little larger than the

third; in MV. crassipyga the fourth and fifth joints are thickened, elongate, and equal

(as in the male of M. forticornis), and to judge from analogy the specimen described is

a male. It has the antenne much shorter and more slender than in M. forticornis ( 3);

the elytra are without an oblique post-basal pubescent fascia; and the pygidium is

much shorter and stouter.

13. Mordellistena forticornis, (Tab. XIV. figg. 6,3; 6a, maxillary palpus.)

Elongate, cuneiform, black ; the head, the prothorax at the sides and base, the scutellum, the elytra with the

extreme base, an oblique stripe extending from the shoulders inwards but not quite reaching the suture,

an oblique patch on the disc a little beyond the middle (widening inwardly and not reaching the suture),

the hind tibial spurs testaceous; the hind tibie with six (including the subapical one, the basal one

abbreviated), the first joint of the hind tarsi with four, and the second joint with two, short, oblique,

parallel ridges.

Length to end of the elytra 33, to tip of the pygidium 44, millim.; breadth 13 millim. (<¢.)

Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith).

One male example. Lasily recognizable amongst its allies by the very long and

comparatively stout antenne in the male sex, the fourth and fifth joints equal in size ;

the last joint of the maxillary palpi is elongate and rather narrow, and has its outer

side concave. The first ridge on the hind tibie is very short; the corresponding

ridge on the first hind tarsal joint is distinct on one leg and obliterated on the other.

14. Mordellistena rufonotata. (Tab. XIV. fig. 7, ¢.)

Elongate, cuneiform, rather narrow, above and beneath black, the elytra with a large reddish spot at the

shoulders ; the suture very narrowly, and a narrow line along each elytron at the sides, to about one

third from the apex, yellowish-cinereous-pubescent, the prothorax with the basal margin narrowly, and

an interrupted line along either side of the disc, similarly pubescent, the rest of the pubescence partaking

of the ground-colour. Head large, broad ; palpi testaceous, the last joint of the maxillary pair piceous at

the tip, the latter (¢) moderately long, stout, scalene-triangular; antennz (d) black with the basal

three joints a little lighter, very elongate, stout, joint 3 short, narrow, 4-11 much thickened, 4-10 sub-

‘equal, very much longer than broad, 11 longer than 10 ; prothorax strongly transverse ; elytra moderately

long, narrowing from the base ; pygidium elongate (the apical half broken off); legs comparatively stout,

black, the tibial spurs testaceous ; the hind tibie with five, the first joint of the hind tarsi with four, the

second joint with two, short, faint, parallel, oblique ridges.

Length to end of the elytra 4, breadth 14, millim. (<¢.)

Hab. Muxtco, Jalapa (Hége).

One male example. This species has the antenne (¢ ) stout and very elongate, and

formed asin WM. forticornis and MM. opalescenticeps, the fourth joint being equal in

length and breadth to the fifth ; it has the last joint of the maxillary palpi shaped as

in the latter. MM. rufonotata is not closely allied to any other Mordellistena here

described. ‘The hind tibiz and the first two joints of the hind tarsi have numerous

very short faint parallel ridges ; and in addition to those mentioned above there are

traces of others on the basal portion of the tibia and of the first tarsal joint.

15. Mordellistena gracilicornis. (Tab. XIV. figg. 8, ¢; 84, maxillary

palpus, ¢; 846, hind leg.)

Elongate, subcuneiform, castaneous or rufo-luteous, the elytra usually with a large triangular common basal

patch, two very oblique fascize of variable extent on the disc, and an anteapical spot piceous, these

markings in some examples completely obliterated ; the pubescence yellowish-cinereous, blackish-brown

on the elytral markings. Palpi testaceous, the last joint of the maxillary pair moderately long, scalene-

sometimes infuscate; pygidium elongate, a little shorter in the female, twice the length of the hypo-

pygium ; legs reddish-testaceous, the hind pair darker; the hind tibiz with five, the first joint of the

hind tarsi with four, and the second joint with two, oblique, parallel ridges.

Length to end of the elytra 33-4, to tip of the pygidium 44-5, millim. ; breadth 13-14 millim. (¢ 9.)

Hab. Guatemata, Cerro Zunil, Mirandilla, Panajachel (Champion).

Six examples—one pair from each of the first-mentioned localities, two females from

Panajachel; the description is made from the former. The two Panajachel females

differ from the others of the same sex in having the third and fourth antennal joints

subequal. A narrower and less robust species than MW. castaneicolor and its allies; the

antenne elongated in the male and much more slender, the pygidium more slender.

From WV. instabilis in all its varieties, some of which have the elytra very similarly

marked, the more elongate shape and the long and slender antenne sufficiently

distinguish it.

16. Mordellistena opalescenticeps. (Tab. XIV. figg. 9, ¢; 9a, antenna.)

Moderately elongate, rather robust, cuneiform, black, the head with a brilliant opalescent lustre; the head,

the prothorax with the base and apex laterally, and the sides indeterminately, the scutellum, the elytra

with a short oblique stripe extending from the shoulders inwards but not reaching the suture, a broad

transverse fascia a little beyond the middle (not quite reaching the suture or lateral margin, slightly

excised in front and behind, and widening a little outwardly), the suture narrowly thence to the base,

and a large spot at the apex of each (not quite reaching the suture), and the base of the pygidium,

yellowish-cinereous-pubescent, the rest of the pubescence brownish-black. Head somewhat flattened in

the middle, obsoletely channelled in the centre behind; palpi (¢) testaceous, the last joint of the

maxillary pair long and stout, scalene-triangular ; antenne ( ¢ ) piceous with the four basal joints reddish-

testaceous, elongate, filiform, joint 3 slender, 4-11 stout, 4 twice as wide as and very much longer than 3,

5-10 decreasing gradually in width, 7-10 very much longer than broad, 11 longer than 10; prothorax

transverse ; elytra moderately long, gradually narrowing from the base; beneath black, the sides of the

breast and the base of each ventral segment yellowish-cinereous-pubescent ; pygidium very elongate,

rather stout, about two and a half times the length of the hypopygium ; anterior legs testaceous, the

middle pair piceous, the hind pair black with the tibial spurs testaceous; the hind tibise with five

(including the subapical one), the first joint of the hind tarsi with four, and the second joint with two,

short, oblique, parallel ridges.

Length to end of the elytra 34, to tip of the pygidium 43, millim.; breadth 1j millim. (¢.)

Hab. Guatemata, Senahu in Vera Paz (Champion).

One male example. Allied to UV. forticornis, from the same sex of which it may be

easily distinguished by the much shorter antenne and longer pygidium, the flattened,

opalescent head, and the stout and much more angular apical joint of the maxillary

palpi. The fourth and fifth joints of the antenne are subequal; this character will

distinguish 1. opalescenticeps from all the varieties of MW. instabilis (3), in which,

however, these organs are paler in colour, shorter, and more slender.

17. Mordellistena sanguinicollis, (Tab. XIV. figg. 10, ; 10a, antenna;

10 4, maxillary palpus.)

Elongate, cuneiform ; the head black with a brilliant opalescent lustre, the prothorax rufous, the elytra with

two rather broad reddish fascie—one a little below the base, extending obliquely upwards to the shoulder

(with the one on the opposite elytron nearly enclosing a broad scutellar patch), the other beyond the

middle, transverse, both interrupted at the suture,—the pygidium broadly rufous at the base, blackish

beyond ; the pubescence on the head, prothorax, scutellum, and elytral fascie, and also (very narrowly)

along the basal half of the suture and at the apex of the elytra, yellowish-cinereous, for the rest brownish-

black. Palpi testaceous, the last joint of the maxillary pair moderately long, scalene-triangular, rather

slender ; antenne piceous with the three basal joints testaceous, joint 3 short, slender, 4 much longer and

stouter than 3, 5 a little wider and about one half longer than 4, 5-11 filiform, moderately thickened,

7-10 subequal, twice as long as broad; prothorax transverse; elytra gradually narrowing from the base ;

beneath black, the posterior coxe and venter, in great part, and the prothorax rufous ; pygidium very

long, twice the length of the hypopygium ; legs testaceous, the hind pair reddish; the hind tibie with

five, the first joint of the hind tarsi with four, and the second joint with two, short, oblique, parallel

ridges.

Length to end of the elytra 3}, to tip of the pygidium 43, millim.; breadth 13 millim. (<¢.)

Hab. Panama, San Feliz in Chiriqui (Champion).

One male example. Somewhat resembling J. forticornis (3), but with the

antenne much less elongate, the fourth joint shorter and narrower than the fifth

though much stouter and longer than the third; the last joint of the maxillary palpi

less elongate ; the thorax, the venter, the pygidium at the base, the elytral fascize, and

the hind legs rufous, the anterior and intermediate legs testaceous. ‘The elytral fascize

in UM. forticornis are formed entirely by the arrangement and colour of the pubescence ;

in MZ. sanguinicollis there is a corresponding difference in the ground-colour.

A single worn specimen from Tolé is perhaps a female of the same species; it has

the antennee very much shorter and more slender, the third and fourth joints subequal,

and the outer eight joints obscure testaceous ; the head pitchy-red ; and the postmedian

fascia of the elytra broken up into two oblong spots. It is considerably smaller than

the male above described.

18. Mordellistena trilinea. (Tab. XIV. figg. 11; lla, maxillary palpus;

114, hind leg.)

Moderately elongate, broad, robust, cuneiform ; the head reddish-testaceous with an opalescent lustre, the eyes,

the prothorax, scutellum, elytra (the extreme apex excepted), and pygidium black, the apex of the

elytra testaceous; the head, the sides of the prothorax indeterminately, the scutellum, the suture and a

sublateral stripe on each elytron to one third from the apex, and also the apex itself, yellowish-cinereous-

pubescent, the rest of the pubescence brownish-black. Head not very convex, obsoletely channelled in

the middle behind; palpi testaceous, the last joint of the maxillary pair moderately stout, scalene-

triangular, the apical side somewhat rounded; antenne obscure testaceous, short, comparatively slender,

narrowing from the base; beneath (the head and prothorax excepted) black, the base of the ventral

segments yellowish-cinereous-pubescent ; pygidium moderately long, twice the length of the hypopygium ;

anterior and middle legs testaceous, the hind pair pitchy-black with the tibial spurs testaceous ; the hind

Length to end of the elytra 34, to tip of the pygidium 44, millim.; breadth 12 millim. ( 2.)

Hab. Panama, Volcan de Chiriqui (Champion).

One example. A stoutly built, rather broad species, with reddish-testaceous head,

palpi, and antenne, and black thorax, elytra (the testaceous tip excepted), and body ;

the sides of the thorax, the suture and a sublateral stripe on the elytra to one fourth

from the apex, and the apex itself, yellowish-cinereous-pubescent.

19. Mordellistena texana.

Mordellistena texana, J. B. Smith, Trans. Am. Ent. Soc. x. pp. 89, 98°.

Elongate, broad, robust, subparallel, black, the head (the eyes excepted) and prothorax rufous ; the pubescence

on the elytra black with intermixed yellowish hairs, for the rest partaking of the ground-colour. Head

large and broad, the eyes large ; maxillary palpi obscure testaceous, short, stout, the last joint triangular,

its inner and apical sides about equal in length; antenne short and stout, obscure testaceous, the five

outer joints piceous, joints 3 and 4 short, about equal in length, 5 nearly twice as long as and very much

wider than 4, 5-10 gradually decreasing in width, 8-10 almost as broad as long, 11 longer than 10;

prothorax not much broader than long; elytra elongate, parallel in their basal half; beneath, the pro-

thorax excepted, black, the base of each ventral segment cinereo-pubescent ; pygidium moderately long,

twice the length of the hypopygium ; legs black, the anterior and middle femora and tibie in great part,

and the hind tibial spurs, testaceous; the hind tibie and the first joint of the hind tarsi each with about

five (the basal one on each indistinct), the second joint of the hind tarsi with three, short, oblique,

parallel ridges.

Length to end of the elytra 44, to tip of the pygidium 54, millim.; breadth 1} millim.

Hab. Norra America, Texas .—Mexico, Monterey in Nuevo Leon (fége).

One example, apparently of the female sex. This species is extremely like J. atri-

pennis, but it has much shorter maxillary palpi, shorter antenna, larger eyes, and the

elytral pubescence with intermixed yellowish hairs. The lateral margin of the thorax

behind, and also the extreme basal margin, is slightly stained with piceous. The

description of WM. texana is inadequate for determination, but so far as it goes it agrees

with our insect.

20. Mordellistena hexastigma. (Tab. XIV. figg. 12, ¢; 12a, maxillary

palpus.)

Moderately elongate, rather robust, cuneiform ; the head and prothorax testaceous, the eyes and the tips of

the mandibles black, the prothorax with traces of a slightly darker broad oblong median vitta anda patch

on either side of it; the elytra piceous, with an oblique stripe extending from the shoulders almost to the

suture (nearly surrounding a common rhomboidal basal spot of the ground-colour), an angulated fascia a

little beyond the middle, the suture and lateral margin beyond this (narrowly), and the apex, flavo-

testaceous ; the pygidium flavo-testaceous at the base, darker towards the tip; the pubescence partaking

of the ground-colour. Head moderately convex ; palpi ( ¢ ) testaceous, the last joint of the maxillary pair

rather long and stout, subtriangular, its inner and apical sides almost equal in length, the outer side

coneave, the second joint stout; antennw (¢) fusco-testaceous with the basal joints paler, short and

slender, joints 3 and 4 short, narrow, subequal, 5-11 widened, equal in width, 5 about twice as long as

the hind tibiew with five (including the subapical one), the first joint of the hind tarsi with four (the

basal one very short), and the second joint with two, short, oblique, parallel ridges.

Length to end of the elytra 3, to tip of the pygidium 32, millim.; breadth 1 millim. (¢.)

Hab. Panama, Bugaba (Champion).

One male example. Deceptively like I. sermaculata (2), but with the antenne

much shorter and more slender, the palpi differently shaped, the pygidium shorter, &c.

The head is without opalescent lustre; the ground-colour of the elytra is piceous, and

the flavo-testaceous markings extend to the lateral margin and also (the oblique basal

one excepted) to the suture; the last joint of the maxillary palpi is wider than in

MM. sexemaculata and has its outer side hollowed out; the third joint of the hind tarsi is

without ridges. From the paler varieties of IZ. instadilis the more angulated elytral

fascize will easily distinguish it.

21. Mordellistena venusta. (Tab. XIV. figg. 13; 13a, hind leg.)

Moderately elongate, robust, cuneiform; the head and prothorax flavo-ferruginous, the head with a brilliant

opalescent lustre, the eyes and the tips of the mandibles black, the elytra black, with a reddish-yellow

oblique stripe on the disc extending from the base some little distance downwards, the pygidium reddish-

yellow to the middle, black beyond; the elytra with an oblique stripe of yellowish-cinereous pubescence

extending from the base to fully four-fifths of their length—this pubescence placed upon and forming a

continuation of the stripe on the surface beneath—and the suture towards the base also with a little

yellowish pubescence, for the rest densely black-pubescent ; the pubescence on the head and prothorax

partaking of the ground-colour and rather sparse. Head moderately convex; palpi testaceous, the last

joint of the maxillary pair piceous, the latter triangular, rather narrow, its inner side not much shorter

than the outer side, the latter nearly twice as long as the apical side; antenne moderately long, com-

elongate, twice the length of the hypopygium ; legs pitchy-brown, all the femora and the base of the hind

tibie testaceous ; the hind tibize with five (including the subapical one, the basal one abbreviated), the

first joint of the hind tarsi with three, and the second joint with two, rather long, oblique, parallel

ridges,

Length to end of the elytra 34, to tip of the pygidium 4, millim.; breadth 13 millim.

Hab. Panama, Volcan de Chiriqui (Champion).

‘One specimen, its sex not ascertained. A species without near ally, as regards

colour and the arrangement of the elytral pubescence. The oblique ridges on the

hind tibie are longer than in I. sexamaculata, &c.: they extend fully halfway across

the outer face of the tibia. The North-American WM. attenuata, Say (vittigera, Lec.),

has the elytra somewhat similarly marked.

22. Mordellistena pictipennis. (Tab. XIV. fig. 14,2.)

Moderately elongate, cuneiform, black; the head, the prothorax with an elongate-triangular mark on either

side of the middle behind—extending forwards nearly to the apex and connected along the basal margin,

interrupted fascia, the outer one the longest), the apex, the suture very narrowly to beyond the middle,

and the extreme base, and also the pygidium at the base, yellowish-cinereous-pubescent, the rest of the

pubescence black. Palpi obscure testaceous, the last joint of the maxillary pair stout, elongate-triangular,

its inner and apical sides about equal in length, both much shorter than the outer side; antenne com-

paratively short, black, the basal four joints testaceous, joints 3 and 4 short, slender, equal in length, 4 a

little stouter than 3, 5-11 moderately widened, 5 nearly twice as broad as and very much longer than 4,

5-10 longer than broad, about equal in length; prothorax transverse; elytra gradually narrowing from

the base; beneath black, the sides of the breast and the base of each ventral segment yellowish-cinereous-

pubescent ; pygidium moderately long, twice the length of the hypopygium ; anterior and middle legs

piceous, the hind pair black with the tibial spurs testaceous; the hind tibie with five, the first joint

of the hind tarsi with four, and the second joint with two, short, oblique, parallel ridges.

Hab. Panama, Volcan de Chiriqui (Champion).

One male example. Differs from all the other Mordellistene here described in the

arrangement of the pubescent markings of the elytra. The fourth joint of the antenne

is slender, asin M. trilinea, &c.; the apical joint of the maxillary palpi is comparatively

_ stout and angular; the pygidium is moderately long.

23. Mordellistena guttifer. (Tab. XIV. fig. 15, 3.)

Moderately elongate, cuneiform, black ; the head, the prothorax with a narrow stripe on the disc, an indistinct

stripe on either side of it, the base, and the sides, indeterminately, the scutellum, the elytra with an

angulated fascia a little below the base, a spot at the shoulders connected with it, another fascia just

beyond the middle (formed by three oblong coalescent spots on each elytron, the outer one much longer

than the others), an angular spot near the suture beyond this, the apex, and the entire suture, narrowly,

and the pygidium, yellowish-cinereous-puhescent, the rest of the pubescence on the elytra purplish-black

and that between the pubescent markings on the prothorax brown. Head moderately convex ; palpi( ¢)

inner and apical sides about equal in length; antenne ( ¢ ) flavo-testaceous, but becoming darker beyond

the middle, the terminal four joints pitchy-brown, comparatively short, rather slender, joints 3 and 4

short, equal in length, 4 a little wider than 3, 5-11 equal in width, broader than 4, 5-10 subserrate,

Hab. Mexico, Cerro de Plumas (ége).

One male example. This small species has the pubescent markings of the elytra

very neatly and sharply defined. The last joint of the maxillary palpi is stout and

triangular. The antenne are comparatively short, not elongated as in the males of

some of the allied forms. In the arrangement of the elytral pubescence, I. guttifer

differs considerably from all the other Mordellistene here described.

Moderately elongate, cuneiform, black or piceous, the mouth-parts testaceous, in some examples the sides of

the prothorax and the elytra and pygidium in part reddish-brown; the elytra each with two fascia of

variable size—one below the base, oblique, extending to the shoulders, the other, oblique or transverse, a

little beyond the middle, the two often connected laterally,—the apex, and the suture, more or less,

yellowish-cinereous-pubescent, the rest of the pubescence black, the markings in dark examples entirely

formed by the colour and arrangement of the pubescence, in the light ones accompanied by a difference in

A very variable and perplexing species, the different varieties of which are more or less

connected by intermediate forms, several of which were obtained in the same localities.

The Caldera specimens possibly belong to a distinct species, but with our limited

amount of material it is inadvisable to separate them. The colour of the head and

thorax varies from black to luteous, and the pubescent elytral markings may or may

not be accompanied by a difference in the gronnd-colour; the antenne and palpi are

testaceous, the outer joints of the former, at most, slightly infuscate. Light-coloured

examples have a common triangular basal patch and two oblique or quadrangular spots

on the disc of each elytron black, and the rest of the elytral surface densely yellowish-

cinereous-pubescent. The post-median pubescent fascia in some specimens is widened

laterally in front and coalescent with the post-basal fascia; in others it is transverse

and not continued upwards. The number of ridges on the hind tibiz and first hind

tarsal joint is variable, the basal one on each of: them being often more or less oblite-

rated. A single specimen from Bugaba perhaps belonging to this species has six

ridges on the hind tibie. IM. instabilis seems to be allied to the North-American

M. pubescens, Fabr.

26. Mordellistena pilosa.

Elongate, cuneiform, robust, black, densely clothed with rather coarse brownish pubescence. Head large,

broad, the eyes not quite reaching the occiput; maxillary palpi testaceous, the apical joint brown or

piceous at the tip, this joint cultriform, very elongate in the male, a little shorter in the female; antennz

black or piceous with the four or five basal joints testaceous, rather stout, moderately long in the male,

shorter in the female, joints 3 and 4 short, 4 a little longer than 3, 5 stouter and very much longer than

4, 5-10 subserrate, decreasing a little in length but equal in width, elongate in the male, shorter in the

female ; prothorax transverse; elytra very long, gradually narrowing from the base; beneath black,

326 HETEROMERA.

cinereous- or yellowish-cinereous-pubescent ; pygidium moderately long in the male, shorter in the female,

twice the length of the hypopygium; legs comparatively stout, black, the anterior pair in great part or

entirely, the middle femora and tibie in some specimens, and the hind tibial spurs testaceous; the hind

tibiee with five, the first joint of the hind tarsi with five (rarely six), and the second joint with three

(rarely four), short, strong, oblique, parallel ridges.

Var. The head, except the eyes and a large patch in the middle behind, and the anterior third of the pro-

thorax, reddish-testaceous.

Length to end of the elytra 4—44, to tip of the pygidium 5-52, millim.; breadth 13-12 millim. (d 2.)

Hab. Mexico, Cordova (Sallé) ; Guatemaa, Capetillo, Duefias (Champion).

Five examples of the type, one of the variety, the latter from Capetillo. An elongate,

robustly-built species, with very elongate, cultriform, apical joint to the maxillary palpi,

and numerous ridges on the hind tibie and first two joints of the hind tarsi, the legs

comparatively stout. It is perhaps nearest allied to M. incana, from which it differs

in the more numerous carine on the hind legs and in the more elongate shape. The

head is narrowly extended on either side behind the eyes; the latter in I. incana

extend to the occiput. From M. murina &c. the less parallel shape, the more

numerous carine on the hind legs, and the longer apical joint to the maxillary palpi

sufficiently distinguish it.

27. Mordellistena longipalpis. (Tab. XIV. figg. 19, ¢ ; 19a, maxillary

palpus; 19, hind leg.)

Elongate, slightly cuneiform, black, the head in front and the prothorax at the sides (to a greater or less

extent) usually testaceous or reddish-testaceous ; the pubescence rather coarse, brownish-cinereous, with

intermixed blackish hairs. Head transverse, very much narrower than the prothorax; maxillary palpi

testaceous, the apical joint in two examples (2) piceous, very long—the last joint in the male very

elongate, cultriform, in the female shorter and with the apex more rounded; antenne slender, filiform,

rather long in the male, slightly shorter in the female, black, the four basal joints testaceous, joint 3 short,

4 a little longer than 3, 5 nearly twice as long as 4, 5-11 moderately elongate ; prothorax broader than

long, somewhat narrowed behind in the male, the hind angles sharply rectangular; elytra elongate, sub-

parallel towards the base ; beneath black, cinereo-pubescent ; pygidium very elongate in both sexes, about

two and a half times the length of the hypopygium; legs black, the anterior femora and tibie usually,

and sometimes part of the middle femora also, and the hind tibial spurs, testaceous ; the hind tibis and

the first joint of the hind tarsi each with four or five, the second joint of the hind tarsi with three, short,

oblique, parallel ridges.

Length to end of the elytra 33-4, to tip of the pygidium 43-5, millim. (¢ 9.)

Hab. Mexico, Omilteme, Chilpancingo, Xucumanatlan, Cuernavaca (H. H. Smith).

Six males and two females. These latter differ from the others in having the head

and thorax black, the apical joint of the maxillary palpi piceous, and the sides of the

thorax more parallel behind ; but there is little doubt they belong to the same species.

In all the males but one the sides of the thorax are testaceous. The dark examples

very closely resemble J. murina; but they are separable therefrom by the longer

maxillary palpi and the less uniformly coloured pubescence, and by the second joint of

the hind tarsi having three (instead of two) ridges. The apical joint of the maxillary

palpi of the male is more elongate and more cultriform than in the same sex of

M. murina. The following, WM. discicollis, is a closely allied species.

MORDELLISTENA. 327

28. Mordellistena discicollis. (Tab. XIV. figg. 20, ¢ ; 20a, hind leg.)

Moderately elongate, subparallel, black, the head in front and the prothorax very broadly at the sides (so as to

leave a black anteriorly narrowed median vitta) testaceous ; the pubescence brownish-cinereous, with

intermixed blackish hairs. Head and prothorax as in WM. longipalpis; maxillary palpi (¢) testaceous,

the last joint piceous, formed very much as in the female of MU. longipalpis ; antennee ( ¢ ) black with the

two basal joints testaceous, filiform, stouter and considerably shorter than in UM. longipalpis (3), joints 3

and 4 very short, subequal, 5 nearly twice as long as 4,5-10 about equal in length but decreasing in

width, not twice as long as broad ; elytra moderately long, subparallel in their basal third ; pygidium

very elongate ; beneath, the head and prothorax excepted, black; legs black, the anterior femora, the

base of the anterior tibis, the basal half of the middle femora, and the hind tibial spurs testaceous ; the

hind tibie and the first joint of the hind tarsi each with four, the second joint of the hind tarsi with

three, oblique, short, parallel ridges.

Length to end of the elytra 3, to tip of the pygidium 3, millim. (<¢.)

Hab. Guatemata, Senahu in Vera Paz (Champion).

One male example only, from the humid forest-region of the Atlantic slope. It has

the antenne and palpi formed very much as in the female of WM. longipalpis.

29. Mordellistena vicina.

Elongate, slightly cuneiform, black ; the pubescence coarse and close, and consisting of intermixed yellowish-

cinereous and black hairs, the latter in one example forming a broad discoidal stripe on the basal two-

thirds of each elytron. Head strongly transverse, narrowly extended on either side behind the eyes, the

latter somewhat prominent; maxillary palpi black, the apical joint (¢) long and stout, cultriform ;

antenne ( ¢) filiform, slender, moderately long, black, joints 2 and 3 or 2-4 testaceous, 4 distinctly longer

than 3, the latter short, 5 about one half longer than 4, 5-11 elongate; prothorax broader than long;

elytra moderately elongate; beneath black, cinereo-pubescent ; pygidium elongate, more than twice the

length of the hypopygium; legs black, the hind tibial spurs testaceous ; the hind tibiz and the first joint

of the hind tarsi each with four or five, the second joint of the hind tarsi with two or three, short, oblique

ridges.

Length to end of the elytra 37-33, to tip of the pygidium 4-44, millim. (¢.)

Hab. Mexico, Omilteme 8000 feet, Chilpancingo 4600 feet, both in Guerrero

(H. H. Smith).

Two male examples. Very near /. murina, var. a, and perhaps only another form

of that variable species; but differing from it by the more transverse head, the eyes

somewhat prominent and not quite reaching the occiput, the apical joint of the maxillary

palpi a little longer and more cultriform, and the elytral pubescence largely intermixed

with black hairs. In both examples the basal joint of the antenne is infuscate.

30. Mordellistena atripennis, (Tab. XIV. figg. 21; 21a, maxillary palpus.)

Elongate, subparallel, moderately broad, black ; the head (the eyes excepted) and prothorax (except the lateral

margins posteriorly) rufous, very finely pubescent ; the elytra with some cinereous hairs along the basal

margin and on the basal fourth of the suture, for the rest entirely black-pubescent. Head moderately

large, the eyes small; maxillary palpi piceous, long and stout, the apical joint elongate-triangular, its

inner and apical sides about equal in length, the outer side concave; antenne black, rather stout,

moderately long, joints 3 and 4 short, subequal, 5 almost twice as long as and very much stouter than 4,

5-10 decreasing in width, longer than broad; prothorax about as long as broad; elytra elongate, sub-

parallel in their basal half; beneath, the head and prothorax excepted, black, yellowish-cinereous-

pubescent ; pygidium slender, comparatively short; legs, the anterior coxw, the base of the anterior

femora, and the hind tibial spurs excepted, black; the hind tibie and the first joint of the hind tarsi each

with four, the second joint of the hind tarsi with three, short, faint, oblique ridges.

Length to end of the elytra 4, to tip of the pygidium 5, millim.; breadth 13 millim.

Hab. Mexico, Guanajuato (Sallé).

One example, probably of the male sex. Very like WM. tevana, of which I at first

supposed it to be the male: the long maxillary palpi, smaller head, small eyes, and the

narrower and relatively more elongate shape will, however, distinguish it from that

species. The pubescence of the elytra, except along the suture anteriorly and along

the basal margin, is uniformly black, that of the under surface being yellowish-cinereous.

The larger size and more elongate shape, stouter limbs, &c., separate I. atripennis

from IM. rubricollis. M. conformis, Smith, from Texas (Bull. Brooklyn Ent. Soc. vi.

p- 4), is similarly coloured and has the carine of the hind legs as in this species ; but

the description is inadequate for determination.

31. Mordellistena incana,

Moderately elongate, broad, cuneiform, bronze-black, the head and prothorax reddish-yellow, the prothorax

broadly infuscate on the middle of the disc behind, the upper and under surfaces very densely and

uniformly clothed with coarse yellowish-cinereous pubescence, the elytral punctuation very dense and fine.

Head very broad, short; palpi obscure testaceous, the last joint of the maxillary pair very elongate,

narrow, obliquely truncate at the apex; antennz black with the basal four joints testaceous, short, mode-

rately stout, joints 3 and 4 about equal in length, 5 stouter but scarcely longer than 4, 5-10 not much

longer than broad, 11 longer than 10; prothorax broad, transverse; elytra gradually narrowing from

the base, moderately long; beneath, the head and prothorax excepted, black; pygidium short and stout,

blunt at the tip, not twice the length of the hypopygium; legs comparatively stout, testaceous, the hind

tibiee and tarsi a little darker, the hind femora piceous ; the hind tibiz with four, the first joint of the hind

tarsi with four (the first abbreviated), and the second joint with two, short, parallel, oblique ridges.

Length to end of the elytra 4, to tip of the pygidium 43, millim.; breadth 14 millim.

Hab. Mexico, San Pedro in Coahuila (Dr. Palmer).

One example. This species differs from all the allied Central-American forms by its

very dense coarse pubescence, the pubescence being similar in colour on the light and

dark portions of the body. The head and thorax are very broad; the pygidium is

short, blunt at the tip; the fifth joint of the antenne is scarcely longer than the fourth ;

the ridges on the hind tibize and tarsi are short, but very sharply defined. It has more

the facies of a Mordella.

82. Mordellistena nigriceps. (Tab. XIV. figg. 22, ¢; 22a, maxillary palpus;

22 6, hind leg.)

Moderately elongate, subcuneiform, the head black, the prothorax and elytra pale castaneous, each elytron

with a blackish spot on the middle of the disc at one third from the apex; the pubescence yellowish-

cinereous, dark brown on the elytral spots. Palpi testaceous, the last joint of the maxillary pair stout

and securiform, its apical side rounded ; antenne testaceous, filiform, rather short, joints 3 and 4 about

equal in length, 4 a little stouter than 3, 5-10 slightly thickened, subequal, nearly twice as long as broad,

5 much longer than 4; prothorax transverse ; elytra very gradually narrowing from the base; beneath

reddish-brown, the breast darker; pygidium elongate, slender, twice the length of the hypopygium ; legs

testaceous, the hind pair darker on the dorsal edge; the hind tibie with four, the first joint of the hind

tarsi with four (the basal one rudimentary), and the second joint with two, short, oblique ridges.

Length to end of the elytra 3, to tip of the pygidium 4, millim.; breadth 1 millim. (¢.)

Hab. Mexico, Jalapa (Hége).

One male example. Easily separable from UV. instabilis in all its varieties (the

form 7 of which resembles it in the elytral markings, when present) by the stout, securi- -

form joint of the maxillary palpi in the male. In its black head ,and yellowish-red

thorax and elytra, the latter with a black spot on the disc of each posteriorly, it differs

from all the allied forms.

33. Mordellistena subsenea.

Hab. GuateMa.a, Capetillo (Champion).

One example. A densely pubescent, elongate, narrow species; the upper surface

with a brassy lustre, the pygidium very slender, the femora and tibie in great part

reddish-testaceous. ‘[he carinz on the hind legs are faint and not easily seen.

34, Mordellistena cinereonotata. (Tab. XIV. fig. 23, 2.)

Rather short, cuneiform, dull black, the elytra with two transverse fascise—one some little distance below the

base and the other beyond the middle, both interrupted at the suture, the anterior one excised on its

anterior and posterior edges and the posterior one interrupted laterally,—the suture from the base to the

middle, and the apex cinereo-pubescent, the pubescence along the base and on either side of the disc of

the prothorax and also that on the head cinereous, for the rest black. Head with a slight opalescent

lustre, channelled in the middle behind; palpi obscure testaceous, the last joint of the maxillary pair

Length to end of the elytra 23, to tip of the pygidium 3, millim.; breadth 1 millim. (9.)

Hab. Panama, Volcan de Chiriqui (Champion).

One female example. Allied to IZ. pictipennis, from which it differs in having the

elytral fasciz more transverse and less interrupted (though in the form of confluent

s pots); the antenne much shorter; the last joint of the maxillary palpi considerably

narrower and less angular ; and the ridges on the hind tibie and first hind tarsal joint

fewer in number.

35. Mordellistena tabascana.

Comparatively short, subcuneiform ; the head luteous or reddish, the prothorax luteous, or piceous with the

margins reddish, the elytra black with a curved oblique reddish-yellow stripe at the shoulders, the basal

half of the pygidium reddish, for the rest black; the elytra with two fascia—one below the base, extend-

Length to end of the elytra 23-23, to tip of the pygidium 3-33, millim.; breadth 3-1 millim. (¢ 2.)

Hab. Mexico, Teapa in Tabasco (H. H. Smith).

Two examples, one, a male, in good condition, the other, a female, mutilated and

without antenne. This species has the facies of a very small example of the var. y of

M. instabilis. The male specimen described differs from M. instabilis ( ¢ ) by the much

narrower apical joint of the maxillary palpi.

36. Mordellistena luteifrons. (Tab. XIV. figg. 24,4, var.; 24a, maxillary

palpus. )

more or less reddish-testaceous ; the pubescence coarse and close, brownish-cinereous, and usually with

intermixed black hairs. Head short, strongly transverse; maxillary palpi black, in one example obscure

testaceous, rather stout, the last joint comparatively short, scalene-triangular ; antenne short in both

sexes, rather stout, black, the basal joints sometimes pitchy-red, joints 3 and 4 short, subequal, 5 stout,

collts, from which it may be separated by the less transverse thorax and by the coarser

elytral pubescence, the latter with intermixed black hairs. MW. nigripilis has a longer

thorax and the elytral pubescence black. In the Sallé collection the two specimens

(3) of the variety are labelled WM. rubronotata, Dugés; and some of those with the

thorax black are ticketed M. luteifrons, Dugés. The head is usually very broad in

both sexes, but in three examples collected by Hége it is smaller and narrower.

37. Mordellistena nigripilis.

Moderately elongate, somewhat cuneiform, above and beneath black, the anterior part of the head sometimes

reddish-testaceous ; the pubescence on the elytra uniformly black, that on the prothorax blackish-brown.

anterior femora also, testaceous ; the elytra with a little brownish-cinereous pubescence at the extreme

base.

Length to end of the elytra 23-33, to tip of the pygidium 34-4, millim. (¢ 9.)

Hab. Mexico, Amula, Chilpancingo, Tepetlapa, Acaguizotla (ZZ. H. Smith), Tupa-

taro ({Hége).

Six examples of the type, three of the variety. Very near I. luteifrons, but differing

elytra moderately long; beneath, the head and prothorax excepted, black, the pubescence brownish-

cinereous; pygidium slender and moderately long in the male, short and conical in the female ; anterior

and middle femora and tibize, and the hind tibial spurs, testaceous, the rest of the legs usually in great

part piceous or black; the hind tibie and the first joint of the hind tarsi each with three or four, the

second joint of the hind tarsi with one or two, short, faint, oblique ridges.

3382 HETEROMERA.

Hab. Guatema.a, San Joaquin in Vera Paz (Champion).

Four examples. This species has the thorax unusually short and very strongly

transverse, the thorax itself and the head peculiarly coloured. The form of the

Hab. Guatemata, Totonicapam 8500 to 10,500 feet (Champion).

Numerous examples, all from the pine-forest region of Los Altos. This is one of

numerous very closely allied species. It is chiefly distinguished by its short, strongly

Length to end of the elytra 3-44, to tip of the pygidium 33-53, millim. (¢ 2.)

Hab. Muxtco, Omilteme, Amula, Chilpancingo, Tepetlapa, Cuernavaca, Atoyac,

Fortin, Teapa (H. H. Smith), Oaxaca, Guanajuato (Sallé), Tupataro (Hége); GuatE-

MALA (Sallé), Duefias (Champion).

A common insect in Mexico. I am quite unable to distinguish more than one species

amongst the large number of specimens before me. Of the var. « we have three male

examples, all from Omilteme; of the var. 8 two only, male and female—the former

from Omilteme, the latter from Chilpancingo. From several of the similarly coloured

forms here described the elongate antenne in the male sex sufficiently distinguish

M. murine.

42. Wordellistena debilis.

Moderately elongate, slightly cuneiform, black, thickly clothed with fine, silky, brown or brownish-cinereous:

pubescence, the pubescence sometimes blackish at the apex of the elytra. Head moderately convex, the

eyes large; palpi varying in colour from pale testaceous to pitchy-brown, the last joint of the maxillary

pair long and subeultriform in the male, shorter and elongate-triangular in the female ; antenne usually

piceous with the four basal joints testaceous, sometimes in great part testaceous, slender, filiform, elongate

in the male, much shorter in the female, joints 3 and 4 short, equal, 5 nearly twice as long as 4, 5-10

subequal, elongate in the male, shorter in the female ; prothorax broader than long; elytra subparallel in

their basal half, moderately long ; beneath black, brownish-cinereous-pubescent ; pygidium very slender,

elongate in the male, shorter in the female; legs black, the front pair usually, the middle pair rarely, and

the hind tibial spurs testaceous; the hind tibie and the first joint of the hind tarsi each with three, the

second joint of the hind tarsi with two, short, parallel ridges.

Var. The head testaceous, with the vertex piceous ; the antenne entirely testaceous ; the prothorax testaceous

with a broad interrupted median vitta, in one example black with a transverse testaceous patch on either

side before the apex.

Length to end of the elytra 2-3, to tip of the pygidium 23-33, millim. (¢ 9.)

Hab. Mexico, Chilpancingo (H. H. Smith); Guatemata, San Gerdnimo, Aceituno,

Capetillo, Duefias (Champion), Coban (Conradt).

Numerous examples of the type, two only of the variety. A perplexing little species,

separable from the allied forms, IZ. murina &c., by its very small size, slender antenne,

and fine brownish pubescence. The colour of the palpi, legs, and antenne is variable.

In some of the females the antenne are shorter than in others. The non-elongated

anterior carina of the hind tibie distinguishes /. debilis from WU. funerea, M. flavicornis,

&c. The thorax is shorter than in I/. flavicornis. Some of the Guatemalan specimens

seem to be more finely pubescent than those from Mexico, but I am unable to separate

them.

43, Mordellistena rubricollis. (Tab. XV. figg. 2,¢; 2a, maxillary palpus.)

Moderately elongate, subparallel, black, the head (the eyes excepted) and prothorax, and sometimes the

scutellum, reddish- or flavo-testaceous, the pubescence partaking of the ground-colour. Head moderately

large; maxillary palpi long, testaceous, the apical joint sometimes infuscate, the latter elongate-triangular

in the male, a little shorter and more bluntly truncate at the apex in the female, the second joint stout in

the male, more slender in the female ; antennz short in both sexes, a little stouter in the female than in

the male, black or pitchy-brown, the basal three or four joints more or less testaceous, joints 3 and 4

short, equal in length, 5 considerably longer and much stouter than 4, 5-10 gradually deereasing in width

but equal in length, longer than broad; prothorax not much broader than long; elytra moderately elon-

gate, subparallel in their basal half; beneath varying in colour from black with the head and prothorax

reddish-testaceous to reddish-testaceous with the venter and pygidium black, the pubescence on the dark

parts brownish-cinereous (of a more ashy colour than that on the elytra); pygidium elongate in the male,

shorter and stouter in the female, about twice the length of the hypopygium; the anterior femora and

tibie, the middle femora (except sometimes at the tip), the middle tibie in some examples, and the hind

tibial spurs, testaceous, the rest of the legs black ; the hind tibia with three or four—the first sometimes

indistinct or obsolete,—the first joint of the hind tarsi with three, and the second joint with two, short,

oblique, parallel ridges.

Length to end of the elytra 24-334, to tip of the pygidium 3-4, millim. (d 9.)

Hab. Mexico, Chilpancingo, Venta de Zopilote, Atoyac, Teapa (H. H. Smith);

GuaTEMALA, El Jicaro in Vera Paz (Champion).

Seven specimens from Mexico and one (¢) from Guatemala. Very like M. azteca,

but differing from that species in the much shorter and less slender antenne in both

sexes, the black (not brownish-cinereous) elytral pubescence, and the shorter pygidium

(especially in the female sex). The short, subequal carine of the hind tibie and

the black elytral pubescence separate M. rubricollis from M. occidentalis. The

underside varies in tint according to the predominance of the reddish or of the

black colour. It is not impossible that MW. rubricollis may prove to be a colour-variety

of UM. nigripilis.

44, Mordellistena azteca. (Tab. XV. figg. 8,36; 3a, maxillary palpus.)

Moderately elongate, narrow, subparallel, black, the palpi, head (the eyes excepted), and prothorax flavo-testa~

ceous or testaceous ; densely sericeous-pubescent, the pubescence on the elytra brownish-cinereous, for the

rest partaking of the ground-colour. Head moderately large; maxillary palpi very long, the last joint

cultriform, long, rather stout; antenne long, very slender, filiform, testaceous, the outer joints usually

darker, joints 3 and 4 short, equal, 5 twice as long as 4, 5-10 elongate, subequal; prothorax a little

broader than long, somewhat strongly rounded at the sides, narrowing a little behind ; elytra moderately

long, subparallel in their basal half; beneath, the head and prothorax excepted, black, brownish-cinereous-

pubescent ; pygidium very elongate, about two and a half times the length of the hypopygium; anterior

and middle legs, the middle tarsi excepted, flavo-testaceous, the hind legs b ack with the tibial spurs

testaceous ; the hind tibie and the first joint of the hind tarsi each with three or four, the second joint

with two, short, oblique ridges.

Var. The prothorax with an oblong stripe on the middle of the disc behind (and the apex in the centre in one

example), and the basal half of the head, more or less infuscate or piceous.

Length to end of the elytra 23-34, to tip of the pygidium 3-47, millim.; breadth 2-1 millim.

Hab. Mexico, Chilpancingo and Amula in Guerrero, Cuernavaca, Teapa (H. H.

Smith).

Numerous examples of the type, two only of the variety. This is one of numerous

very closely allied Mexican species, and it may be only a colour-variety of MZ. murina.

Its chief characters are:—the long and slender antenne, with joints 3 and 4 short

and equal, the long maxillary palpi, the apical joint of which is cultriform in shape,

the long pygidium, &c. The ridges on the hind tibie are short, this character

readily separating M. azteca from WM. occidentalis. Sexual differences I am unable to

detect.

45. Mordellistena rufopyga. |

Moderately elongate, parallel, black, the head (the eyes excepted) and prothorax reddish-testaceous, the antenne

and palpi testaceous, the pygidium reddish, the pubescence partaking of the ground-colour. Head broad,

short, the eyes large; maxillary palpi rather stout, the last joint triangular, oblong, its inner and apical

sides about equal in length; antennz comparatively stout, filiform, moderately long, joints 3 and 4 very

short, subequal, 5 two anda half times as long as 4, 5-10 about equal in length and width, 11 longer than

10; prothorax a little broader than long; elytra moderately long, parallel in their basal half; beneath

with the head, prothorax, the middle of the breast, and the last two ventral segments reddish-testaceous,

for the rest black ; pygidium elongate, about two and a half times the length of the hypopygium ; anterior

and middle legs testaceous, the hind pair (the tibial spurs excepted) in great part piceous; the hind tibize

and the first joint of the hind tarsi each with three, the second joint of the hind tarsi with two, short,

oblique, parallel ridges.

Length to end of the elytra 23, to tip of the pygidium 3, millim. (¢.)

Hab. Guatemata, Capetillo (Champion).

One male example. Smaller and less elongate than IZ. rubdricollis; the antenne( ¢ )

a little longer, and with their joints 5-11 equal in width, 5 longer than 3 and 4 united ;

the maxillary palpi less elongate, and with a much shorter apical joint; the head more

transverse ; the pygidium and last two ventral segments reddish, the former more elon-

gate; the elytral pubescence black. The stouter and less elongate antenne, short

tibial carine, &c., distinguish it from UZ. filicornis.

46. Mordellistena sparsa. (Tab. XV. figg. 4,3; 4a, maxillary palpus.)

Moderately elongate, narrow, subparallel, above and beneath, the antenne, palpi, and legs (except the hind

tibial spurs, which are testaceous) black, densely and rather coarsely pubescent ; the elytra from the base

to the apex with small, somewhat closely placed, transverse, partly confluent, irregular patches of cinereous

or yellowish-cinereous hair, for the rest black-pubescent, the pubescence on the head and prothorax in

part cinereous. Maxillary palpi stout, the last joint moderately long, triangular ; antennee comparatively

short, joints 3 and 4 short, narrow, subequal, 5-11 moderately thickened, 5 much longer and stouter than

4, 5-10 equal in width and length, about as broad as long, 11 very much longer than 10; prothorax

broader than long; elytra moderately elongate, subparallel in their basal half; beneath in great part

cinereo-pubescent ; pygidium comparatively stout, moderately long, shorter and blunter in some examples,

about twice the length of the hypopygium ; the hind tibie and the first joint of the hind tarsi each with

two (rarely three) short, faint, oblique ridges near the tip, the second joint of the hind tarsi with one or

two ridges.

Length to end of the elytra 2-3, to tip of the pygidium 24-31, millim. (¢ 2.)

Hab. Mexico, Saltillo in Coahuila (Dr. Palmer), Chilpancingo, Xucumanatlan,

Mexico city (H. H. Smith), Puebla, Guanajuato (Sallé), Tupataro (Hége), Amecameca

(Flohr).

Not uncommon in Central and Northern Mexico, whence we have received numerous

examples. I am unable to identify the species with any of those described from North

America. ‘The pygidium varies in length, it being shorter and stouter in some males

than in others. The legs, antenne, and palpi are black.

47. Mordellistena dispersa.

Broader, larger, and more robust than M. sparsa; the upper surface with a brassy lustre; the antenne, palpi,

and legs similar in form and colour; the dense coarse pubescence consisting of intermixed dark brown and

yellowish-cinereous hairs, the light-coloured hairs on the elytra not forming distinct, transverse, irregular

patches, but seattered here and there (as on the prothorax) over the surface ; head large and broad, almost

as wide as the prothorax, the latter broad, strongly transverse; the pygidium stout, conical, short; the

hind tibie and the first joint of the hind tarsi each with four, the second joint of the hind tarsi with two,

short oblique ridges.

Length to end of the elytra 34, to tip of the pygidium 43, millim. (@.)

Hab. Mexico, Amula in Guerrero 6000 feet (7. H. Smith).

One specimen only, apparently quite distinct from M/. sparsa. The pubescence

consists of intermixed dark brown (not black) and yellowish-cinereous hairs, the latter

showing no tendency to form transverse fascicles on the elytra as in W/. sparsa; the

carine on the hind legs are also more numerous.

48. Mordellistena tessellata. (Tab. XV. figg. 5, ¢; 5a, maxillary palpus.)

Moderately elongate, very narrow, subparallel, above and beneath black, the pubescence dense and rather

coarse ; the elytra with numerous rather large, transverse or oblique, patches of cinereous hair, these

patches tending to form irregular fascie, for the rest black-pubescent; the pubescence on the head and

prothorax, and at the base of the pygidium, partly cinereous. Head very convex ; maxillary palpi (¢ )

piceous with the basal joints paler, the apical joint very long, stout, and cultriform; antennz (¢ ) mode-

rately long, slender, filiform, piceous, the four basal joints flavo-testaceous, joints 3 and 4 subequal,

5 considerably longer but not much stouter than 4, 5-10 equal in length and breadth, much longer than

broad, 11 very much longer than 10; prothorax a little broader than long; pygidium moderately elon-

gate; legs black, the anterior cox flavo-testaceous, the hind tibial spurs piceous; the hind tibie with

three, the first and second joints of the hind tarsi each with two, very short oblique ridges near the tip.

Length to end of the elytra 14, to tip of the pygidium 27, millim.; breadth 3 millim. (¢.)

Hab. Mexico, Amula in Guerrero 6000 feet (H. H. Smith).

One male example only of this minute species has been received. Very like J. sparsa,

but easily separable from the same sex of that insect by the much more elongate apical

MORDELLISTEN A. ; 337

joint of the maxillary palpi, the slender antenne, the four basal joints of which are

yellow and the fifth joint not very much stouter than the fourth, &c. The patches of

cinereous pubescence on the elytra are larger and less numerous, and they tend to form

irregular zigzag fascie; the anterior coxe are yellow, the hind tibial spurs piceous.

49. Mordellistena quadrifasciata. (Tab. XV. fig. 6.)

Moderately elongate, narrow, subparallel, black, finely and rather sparsely pubescent ; the elytra with nume-

rous, transverse, irregular patches of yellowish-cinereous hair, these patches forming four zigzag fascie,

for the rest blackish-brown-pubescent, the head and prothorax partly cinereo-pubescent. Head very

convex ; maxillary palpi pitchy-brown, the apical joint moderately stout, somewhat cultriform; antenne

piceous with the four basal joints obscure testaceous, moderately long, joints 3 and 4 short, equal, 5 very

much longer and stouter than 4, 5-10 equal in width and length, a little longer than broad, 11 much

longer than 10; prothorax almost as long as broad ; pygidium elongate ; legs black, the hind tibial spurs

testaceous ; the hind tibie and the first joint of the hind tarsi each with three, the second joint of the hind

tarsi with two, very short, oblique ridges near the tip.

Length to end of the elytra 24, to tip of the pygidium 3, millim.

Hab. Mexico, Northern Sonora (Morrison).

One specimen. Very near JZ. sparsa and M. tessellata: from the former it differs by

its longer thorax and finer pubescence, and by the cinereous patches on the elytra being

much less scattered and forming four zigzag fascie; from the latter it may be distin-

guished by the less slender antenne and by the more regular arrangement of the sparser

and finer elytral pubescence.

50. Mordellistena cincta.

Short, cuneiform, black, the mouth-parts testaceous: the elytra with the base, a median fascia, and in one

specimen the apex broadly, yellowish-cinereous-pubescent, the rest of the elytral pubescence in great part

black, that on the head and prothorax brownish. Head very convex; maxillary palpi testaceous or brown,

the last joint in both sexes elongate-triangular with the inner apical angle almost rounded; antenne

pitchy-brown with the four basal joints testaceous, slender, filiform, elongate in the male, shorter in the

female, joints 8 and 4 short, equal, 5 fully twice as long as 4, 5-10 in the male elongate, subequal, in the

female a little shorter ; prothorax broader than long; elytra comparatively short; pygidium elongate,

more than twice the length of the hypopygium; legs black, the anterior femora and tibiz obscure testa-

ceous, the hind tibial spurs testaceous ; the hind tibize with three, the first and second joints of the hind

tarsi each with two, short, oblique ridges.

Length to end of the elytra 13-1}, to tip of the pygidium 2-23, millim. (¢ 9.)

Hab. GuateMALa, Zapote, San Gerénimo (Champion).

Two examples. This very minute species closely resembles M. perexiqua and

M. pulicaria; but it has very much longer antennex, the last joint of the maxillary

palpi very similarly formed in both sexes, and the carine on the hind legs differently

arranged. MV. cincta is perhaps nearest allied to M. annulipyga, from which its longer

and more slender antenne and pygidium, narrower apical joint of the maxillary

palpi, much smaller size, &c., sufficiently distinguish it. The cinereo-pubescent median

fascia and apical patch are well marked in the female, but in the male they are not

very distinct.

Elongate, narrow, subparallel, shining; the head (the eyes excepted), prothorax, and scutellum flavo-testaceous ;

the elytra piceous, each with the middle of the disc anteriorly testaceous or brownish (the sides and apical

half, and the suture also in one example, more or less piceous); the pygidium obscure testaceous ; the

pubescence sparse and partaking of the ground-colour. Head moderately large, the eyes small ; maxillary

palpi obscure testaceous, the last-joint quite slender, elongate-ovate ; antenne moderately long, rather

the last two ventral segments slightly infuscate; pygidium very slender and elongate, at least three times

the length of the hypopygium ; legs flavo-testaceous, the carine on the hind legs piceous; the hind tibize

with three ridges—the first and second oblique, parallel, extending halfway across the outer face of the

tibia, the third (subapical) short; the first joint of the hind tarsi with two oblique ridges, the second

joint with one only.

Length to end of the elytra 3-34, to tip of the pygidium 3-4, millim.

Hab. Guatemata, Calderas on the slope of the Volcan de Fuego 7000 feet (Cham-

pron).

Two examples, apparently male. and female, one of them having a longer pygidium

than the other. This species differs from all others of the genus here described by

the very narrow, elongate-ovate apical joint of the maxillary palpi. The antenne are

comparatively stout, their fourth and fifth joints subequal, the fourth much longer and

stouter than the third ; the pubescence is quite sparse ; the pygidium is very elongate

and slender.

triangular, its inner and outer sides somewhat concave; antennee piceous with the basal four joints testa-

ceous, long and slender, filiform, joints 3 and 4 short, equal, together as long as 5, 5-11 very little thick-

ened, subequal, more than twice as long as broad; prothorax transverse; elytra elongate, subparallel in

three times the length of the hypopygium; anterior and middle legs in great part testaceous, the hind

pair piceous with the tibial spurs testaceous ; the hind tibiee with four oblique ridges—the first abbrevi-

ated, the second very long, extending across the outer face of the tibia to near the base, and sometimes

interrupted in the raids, the others short; the first joint of the hind tarsi with four or five, and the

second joint with two or three, parallel ridges.

Length to end of the elytra 33-4, to tip of the pygidium 54-53, millim.

Hab. Mexico (Boucard '), Cordova (Sallé).

The ridges on the hind tibie are rather irregular and sometimes interrupted. ‘The

pygidium is exceedingly elongate. Three specimens of this species are contained in the

Sallé collection, two of which are males.

MORDELLISTEN A. 339

53. Mordellistena mutabilis. (Tab. XV. figg. 9,2; 10,3, var.; 11,9, var.)

Moderately elongate, narrow, subparallel, black, the head pitchy-brown or reddish-testaceous ; the prothorax

with an obscure testaceous spot at the sides in front in one example; the elytra each with a large flavo-

testaceous patch immediately below the base (extending to the lateral margin, but not to the suture, and

obliquely cut off behind) and a large, oblong, obscure testaceous patch on the disc beyond the middle (very

narrowly interrupted at the suture); the pygidium piceous, reddish at the base; the pubescence on the

elytral markings yellowish, for the rest partaking of the ground-colour. Head rather elongate, the eyes

not very large; maxillary palpi testaceous, the last joint elongate-triangular, comparatively narrow, its

apical side as long as the inner side, the inner apical angle rounded; antenne testaceous, slender, filiform,

moderately long in the male, considerably shorter in the female, joints 3 and 4 short, together not much

longer than 5, 4 slightly longer than 3, 5-11 very little stouter, subequal, in both sexes very much longer

than broad; prothorax nearly as long as broad; elytra moderately long, subparallel in their basal half;

beneath black, with the apex of the ventral segments, in one example the entire apical one, testaceous ;

pygidium very elongate and slender; legs testaceous, the hind pair and the middle femora piceous or

infuseate, the anterior tibie a little thickened in the male; the hind tibie with three oblique ridges—

the first extending across the outer face of the tibia to near the base, the second much shorter, the third very

short; the first joint of the hind tarsi with three, the second joint with two, oblique ridges.

Var.a. The prothorax and elytra black, the latter with a flavo-testaceous oblique spot below the shoulders only.

(Fig. 10.) .

Var. 6. The elytra fusco-testaceous, paler towards the base, with the suture—broadly at the base, very narrowly

beyond,—and the sides at the middle, black or piceous; the sides of the prothorax broadly, the pygidium,

and the posterior coxe sometimes obscure testaceous ; the apical joints of the antenne slightly infuscate.

Var. y. Testaceous, the prothorax with a black spot on the disc; the elytra flavo-testaceous, with the base

narrowly, an angulated ante-median fascia (widening outwardly, interrupted on the disc in one example),

the suture from this to the base, and in one specimen the apex, black. (Fig. 11.)

Var. 6. Testaceous, the sides of the elytra narrowly from the base to the middle and the anterior portion of the

breast piceous.

Hab. Mexico, Chilpancingo, Teapa (H. H. Smith), Cordova (Sallé), Jalapa (Hoge) ;

GuaATEMALA, Cerro Zunil, San Geronimo, Lanquin (Champion); Panama, Bugaba, Volcan

de Chiriqui (Champion).

A very variable species, according to the predominance of the black or of the testa-

ceous colour. Ten examples are referred to it: two of the typical form (from Cordova

and Lanquin), two of the var. a (from Guatemala), three of the var. 6 (from Mexico),

two of the var. y (from Chiriqui), and one of the var. 8 (from Jalapa). ‘The var. 8

closely resembles M. luteola and M. distorta; but it is separable from both these by

its much smaller eyes, and from the former also by its less elongate shape. The var. y

has the elytra marked very much as in J. crux; but it differs from that species in its

longer thorax and in the number and arrangement of the ridges on the hind legs. The

var. « (of which both sexes have been obtained) is perhaps distinct ; it has the elytra

marked as in UM. curvimana. Numerous North-American forms (some of which, as

noted by J. B. Smith, are evidently no more than colour-varieties of one or the other)

are closely allied to this, e.g. WZ. andrew, M. varians, M. ustulata, M. semiusta, &c.

Hab. Mexico, Cerro de Plumas (Hoge), Teapa (H. H. Smith); Guatemana, Cuabil-

guitz (Champion); Panama, Bugaba (Champion).

One male and three female examples, the male being from Bugaba. Very near

M. distorta, but easily separable in the male sex by the form of the anterior tibie

and tarsi: the tibiee, instead of being broadly flattened, are merely a little thickened

and sinuous, and the tarsi have their first joint very feebly curved. ‘The eyes are equally

large in the two species.

55. Mordellistena isabellina. (Tab. XV. figg. 12; 12a, hind leg.)

Very elongate, narrow, cuneiform, above, the oral organs, antennez, and legs brownish-yellow, beneath reddish-

testaceous, the eyes black, the hind tibia and tarsi slightly infuscate along their dorsal edge, the pubescence

uniform. Head rather elongate, the eyes large; last joint of the maxillary palpi elongate, rather narrow,

its inner and apical sides about equal in length, the inner apical angle rounded ; antenne very slender,

filiform, comparatively short, joints 3 and 4 short, narrow, subequal, together about as long as 5, 5-11

legs very elongate; the hind tibize with three parallel oblique ridges—the first extending across the outer

face of the tibia to near the base, the others short; the first joint of the hind tarsi with three, the second

joint with two, oblique ridges.

Length to end of the elytra 33, to tip of the pygidium 43, millim.; breadth 1 millim.

Hab. Guatemata, Capetillo (Champion).

One example, probably of the female sex. Closely resembling M. luteola, but more

cuneiform ; the elytra relatively much longer, distinctly narrowing from the base, the

antenne with joints 5-11 more slender, the last joint of the maxillary palpi less angular,

the pygidium stouter, and the eyes a little smaller. On the hind tibie and on the first

joint of the hind tarsi there are traces of a short additional ridge in front of the

others.

eyes moderately large ; last joint of the maxillary palpi rather stout, elongate, subsecuriform ; antenn

filiform, slender, comparatively short, joints 3 and 4 short, subequal, together. as long as 5, 5-11 about

twice as long as broad, subequal ; prothorax as long as broad; elytra elongate, subparallel in their basal

half ; (pygidium broken off); the hind tibiee with three oblique ridges—the first extending across the outer

face of the tibia to near the base, the others short; the first joint of the hind tarsi with three, the second

joint with two, oblique ridges.

Moderately elongate, narrow, subparallel, black, the head (the eyes excepted) and prothorax flavo- or reddish-

testaceous, the base of the pygidium sometimes reddish; the pubescence on the elytra brownish or

brownish-cinereous, for the rest partaking of the ground-colour. Head moderately large; maxillary palpi

testaceous, darker at the tip, the last joint elongate-triangular and with its outer side slightly concave ;

across the outer face of the tibia to near the base, the second short, the third (subapical) very short; the

first joint of the hind tarsi with three, the second joint with two, short, oblique ridges.

Length to end of the elytra 23-33, to tip of the pygidium 3-33, millim. (¢ 9.)

Hab. Muxtco, Chilpancingo in Guerrero 4600 feet (1. H. Smith).

Numerous examples. Easily separable from all the allied forms, the following three

species excepted, by the position of the carine on the hind tibie: of these the first

extends completely across the outer face of the tibia. In the form of the antenne and

the colour of the pubescence J. occidentalis is very similar to MM. azteca.

58. Mordellistena oculata.

Elongate, narrow, subparallel, pitchy-black, the head (the eyes excepted) reddish-testaceous ; the pubescence

tarsi with three, the second joint with two, sharp, oblique ridges.

Length to end of the elytra 33, to tip of the pygidium 33, millim. (<¢.)

Hab. Mexico, Zacualtipan in Hidalgo (Hége).

One male example. Very near MV. occidentalis; but differing from the same sex of

that species by its very elongate antenna, the fifth joint of which is more than twice as

long as the fourth, the larger and more coarsely faceted eyes, and the piceous thorax.

The antenne are not so slender as in WM. filicornis (¢ ).

59. Mordellistena filicornis. (Tab. XV. fig. 14, ¢.)

Moderately elongate, subparallel, very narrow, pitchy-brown, the head (the eyes excepted), antenne, palpi, and

prothorax flavo-testaceous, the pygidium reddish at the base ; the pubescence fine, on the elytra brownish-

cinereous, for the rest partaking of the ground-colour. Head exceedingly convex, the eyes unusually large;

hind tibise with three ridges—the first extending obliquely across the outer face of the tibia to near the

base, the others short, subequal; the first joint of the hind tarsi with three, the second joint with two,

short, oblique ridges.

Length to end of the elytra 23, to tip of the pygidium 3, millim.; breadth 2 millim. (¢.)

Hab. GuaTEMALA, Zapote (Champion).

One male example. Narrower and much smaller than J. occidentalis (3); the

eyes larger and more coarsely faceted ; the antenne longer, more slender, and entirely

flavous. ‘The carine on the hind legs are piceous, and, owing to the pale colour of

these limbs, very prominent.

60. Mordellistena flavicornis. (Tab. XV. fig. 15.)

Moderately elongate, subparallel, black, the head (the eyes excepted) reddish-testaceous, the palpi and antennxe

flavous, the pygidium reddish at the base; finely sericeous-pubescent, the pubescence on the dark parts

brownish-cinereous, purplish on the elytra in certain lights. Head moderately convex, the eyes large and

coarsely faceted ; last joint of the maxillary palpi scalene-triangular, moderately long, rather stout; antenne

short and slender, subfiliform, joints 3 and 4 short, equal, 5 nearly twice as long as 4, 5-10 subequal,

longer than broad, 11 one half longer than 10; prothorax nearly as long as broad; elytra moderately

long, subparallel in their basal half; beneath, the head excepted, black, the last ventral segment testa-

ceous, cinereo-pubescent ; pygidium very elongate ; the anterior legs flavous, the middle legs pitchy-brown,

the hind legs (the tibial spurs excepted) piceous ; the hind tibiz with three well-defined ridges—the first

extending across the outer face of the tibia to near the base, the others short, equal in length; the first

joint of the hind tarsi with three, the second joint with two, oblique, well-defined ridges.

Length to end of the elytra 24, to tip of the pygidium 34, millim.

Hab. GuatemMata, Duefias (Champion).

Two examples, apparently females. Closely allied to M. filicornis, but differing from

that insect in having the antenne one third shorter, the head less convex, the eyes a

MORDELLISTEN A. 34:

little smaller, the prothorax and underside (the last ventral segment excepted) black,

and the intermediate legs pitchy-brown. At first sight, WZ. flavicornis would appear to

be a variety of the female of WV. filicornis; but the difference in the form of the

antennee is much greater than in the sexes of the allied species.

61. Mordellistena funerea.

Moderately elongate, narrow, subparallel, black; the pubescence sericeous, fine, uniformly brown. Palpi

black, piceous, or obscure testaceous, the last joint of the maxillary pair long and subcultriform in

the male, shorter in the female; antenne moderately long in the male, a little shorter in the female,

slender, filiform, black, the four basal joints usually obscure-testaceous, joints 3 and 4 short, equal, 5

stouter than and about twice as long as 4, 5-10 subequal, longer than broad ; prothorax nearly as long

as broad; elytra moderately long, subparallel in their basal half; beneath black, brownish-cinereous-

pubescent; pygidium very elongate, about two and a half times the length of the hvpopygium ; legs black,

the anterior femora and the anterior and middle tibia sometimes obscure testaceous, the hind tibial spurs

flavous ; the hind tibiee with three well-defined ridges—the first extending across the outer face of the

tibia, the others short; the first joint of the hind tarsi with three, the second joint with two, oblique,

parallel ridges.

Length to end of the elytra 2-33, to tip of the pygidium 25-4, millim. (¢ 2.)

Hab. Mexico, Chilpancingo (H. H. Sinith, Hoge), Tierra Colorada, Teapa (H. H.

Smith); Guatemaua, Chiacam, Tamahu (Champion).

Nine examples, varying greatly in size. Exceedingly like MW. murina and only

separable therefrom by the elongated anterior carina of the hind tibie. M. funerea is

the only unicolorous Central-American species possessing this peculiarity. The last joint

of the maxillary palpi is almost cultriform in shape in the male. From M. occidentalis,

of which it may prove to be acolour-variety, it differs in the black head and thorax and

darker limbs. The eyes are more finely faceted and the antenne much shorter than in

M. oculata (3).

62. Mordellistena distorta. (Tab. XV. figg.16,¢; 16a, antenna; 16 4, ante-

rior tibia and tarsus ; 16 ¢, hind leg.)

3. Elongate, narrow, subparallel, above and beneath, the oral organs, and antenne flavo-testaceous, the eyes

black, the elytra slightly infuscate at the sides about the middle and also posteriorly, the pubescence

uniform. Head comparatively long, very convex ; the eyes exceedingly large, occupying the whole of the

side of the head, coarsely granulated; last joint of the maxillary palpi elongate, not very stout, scalene-

triangular ; antenne slender, filiform, moderately long, joints 3 and 4 very short, subequal, the two

together shorter than 5, 5-11 elongate, subequal, rather more than twice as long as broad; prothorax as

long as broad; elytra elongate, subparallel in their basal half; pygidium exceedingly elongate, slender,

about three times the length of the hypopygium; legs very elongate, flavo-testaceous, the hind pair

slightly darker, the intermediate pair very slender; anterior tibiz very broadly dilated and flattened, the

inner edge almost straight for the greater part of its length and then rounded to the apex, the outer edge

sparsely setose and a little rounded, armed on the lower side near the outer apical angle with a very fine

sbarp black spur; anterior tarsi with joint 1 as long as the others united, very strongly curved inwards,

exceedingly slender for two-thirds of its length, and becoming club-shaped at the apex, joints 2 and 3

moderately dilated, 4 short and narrow, slightly lobed beneath ; the hind tibiz with three oblique parallel

ridges—the first extending across the outer face of the tibia to near the base, the second much shorter

344 HETEROMERA.

the third (subapical) very short; the first joint of the hind tarsi with three, the second joint with two,

oblique ridges.

Length to end of the elytra 24, to tip of the pygidium 33, millim.; breadth 7 millim.

Hab. Nicaracua, Chontaies (Janson).

One immature male example of this extraordinary species has been received. ‘The

very abnormal form of the anterior tibiz and tarsi of the male separates MM. distorta

from all the known members of the genus, the following excepted. In other respects

the species is exceedingly close to MJ. luteola.

63. Mordellistena curvimana. (Tab. XV. figg. 17, ¢; 17a, anterior tibia

and tarsus.)

3. Elongate, subparallel, rather narrow, the head, oral organs, antennew, and prothorax testaceous, the eyes

and elytra black, the latter with a large, oblong, slightly oblique, testaceous spot immediately below the

shoulders (not quite reaching the base or lateral margin), the pygidium infuscate, reddish at the base ;

the pubescence on the dark parts brownish, for the rest partaking of the ground-colour. Head compara-

tively long; the eyes moderately large, somewhat finely granulated ; last joint of the maxillary palpi elongate,

moderately stout, scalene-triangular ; antennee long and very slender, filiform, joints 3 and 4 short, together

barely as long as 5, 4 a little longer than 3, 5-11 very elongate and thin, about three times as long as

broad; prothorax as long as broad; elytra very long, subparallel in their basal half; beneath testaceous,

the ventral segments 1—4 in great part piceous; pygidium very elongate and slender, nearly three times

the length of the hypopygium ; legs very elongate, flavo-testaceous, the hind tibie and tarsi darker ;

anterior tibise very broadly, triangularly dilated and flattened—the inner edge straight to a little beyond

the middle and then cut off obliquely to the apex, the outer edge almost straight and finely and densely

setose; anterior tarsi with joint 1 nearly as long as the others united, curved inwards, slender to

about the middle, and then gradually widened to the apex, joints 2-4 elongate and slender, 3 and 4

subequal ; intermediate tibie sinuous within ; the hind tibie with three oblique parallel ridges—the first

interrupted in the middle and extending across the outer face of the tibia to near the base, the second

shorter, the third very short ; the first joint of the hind tarsi with three, the second joint with two, rather

long, oblique ridges.

Length to end of the elytra 3, to tip of the pygidium 4, millim.; breadth 3 millim.

Hab. Guatemata, Cerro Zunil (Champion).

One male example. Allied to WV. distorta, but differing from the same sex of that

species by the smaller and less coarsely granulated eyes, the longer and more slender

antennee, the triangularly dilated anterior tibiz, &c.; the anterior tarsi have their first

joint less curved and not so thin towards the base, and the penultimate joints longer

and more slender. The anterior ridge on the hind tibiz is interrupted in the middle, but

this is probably abnormal.

64. Mordellistena xanthopyga. (Tab. XV. figg. 18,9; 18a, hind leg.)

Short, cuneiform, the head reddish-testaceous, the prothorax black with the sides yellow (broadly so posteriorly),

the scutellum and elytra black, the latter with two transverse yellow fascize—one before, the other beyond

the middle, the anterior one broadly interrupted at the suture, the posterior one entire,—the pygidium

flavo-testaceous, the pubescence partaking of the ground-colour. Head short and broad, the eyes rather

small; palpi testaceous, the last joint of the maxillary pair more than twice as broad as long and some-

what hammer-shaped in the male, elongate-triangular in the female; antenne very short in both

sexes, testaceous, the apical two or three joints slightly darker, joints 3 and 4 narrow, subequal, 5-11

a little thickened, 5-10 scarcely longer than broad, 11 a good deal longer than 10; prothorax transverse :

elytra comparatively short, gradually narrowing from the base; beneath in great part black, the last

ventral segments yellow ; pygidium very elongate in both sexes, two and a half times the length of the

hypopygium ; legs more or less testaceous, the hind pair, and also the middle femora, piceous; the hind tibize

with three sharp ridges—the first extending across the outer face of the tibia, the second one-half shorter,

the third very short, subapical; the first joint of the hind tarsi with two rather long oblique ridges, the

second joint with one only.

Length to end of the elytra 13-2, to tip of the pygidium 23-24, millim. (¢ 2.)

Hab. Mextco, Amula in Guerrero (H. H. Smith).

Three examples. Easily separable from the other similarly-coloured species, /. bi-

cinctella &c., by the first ridge of the hind tibie extending obliquely across their

outer face to near the base. The first joint of the maxillary palpi in the male, as in

M. palpalis, is wn0ore than twice as broad as long and somewhat hammer-shaped.

M. amica, Lec., and M. minuta, Smith, both from Georgia, have the hind legs formed

as In this insect.

65. Mordellistena nigerrima. (Tab. XV. figg. 19; 19a, antenna; 198,

hind leg.) :

Rather short, slightly cuneiform, moderately broad, above and beneath, the legs (including the hind tibial

spurs), palpi, and antenne black; the pubescence of the upper surface very fine, silky, black. Head

broad, short, the eyes large; last joint of the maxillary palpi moderately stout, elongate-triangular, its

inner and apical sides about equal in length, the inner apical angle rounded ; antenne extremely short,

stout, joints 3 and 4 narrow, very short, equal, 5 about twice as wide as and much longer than 4, 5-11

subparallel in their basal half; beneath with some cinereous pubescence on the breast and on the base of

each ventral segment ; pygidium short, stout, conical ; the hind tibiee with three, the first joint of the hind

tarsi with two, short, faint ridges near the tip, the second joint of the hind tarsi simple.

Length to end of the elytra 23-3, to tip of the pygidium 33-33, millim.; breadth 3 millim. (9.)

Hab. Mexico, Saltillo in Coahuila (Dr. Palmer), Tupataro (Hége).

Two examples, apparently both females. The form of the antenne and the very fine

black silky pubescence of the upper surface chiefly distinguish this little species from

the other black Mordellistene here described. The antenne, palpi, and legs are entirely

black. The second joint of the hind tarsi is without ridges.

66. Mordellistena annulipyga. (Tab. XV. figg. 20, ¢; 20a, hind leg.)

Comparatively short, cuneiform, above and beneath black, the oral organs, the basal half of the pygidium, and

the last ventral segment testaceous ; the elytra with two cinereo-pubescent fasciee—one before, the other

beyond the middle, the first broad, angulate on its anterior edge, the second narrower, straight,—for the

rest black-pubescent ; the pubescence on the head and prothorax cinereous. Last joint of the maxillary

palpi piceous, long and stout, scalene-triangular ; antenne obscure testaceous, darker towards the tip, short

and slender, joints 3 and 4 subequal, 5-10 a little stouter, not much longer than broad, 5 slightly longer

than 4,11 very much longer than 10; prothorax transverse ; elytra comparatively short, gradually

narrowing from the base; pygidium elongate, stout, twice the length of the hypopygium ; anterior and

middle legs testaceous, the hind pair (the spurs excepted) piceous; the hind tibize with three, the first

joint of the hind tarsi with two, short, oblique, parallel ridges.

_ One female example. In the arrangement of the elytral pubescence this species

resembles M/. palpalis, from the same sex of which it differs in its larger size, more

elongate shape, black head, stouter pygidium, and the very much stouter and more

angular apical joint of the maxillary palpi. The pubescence is rather sparse. The

second hind tarsal joint is without ridges.

“pp. 85, 90, t. 2. figg. 15, 16°; Bull. Brooklyn Ent. Soc. vi. p. 3.

Short, subparallel ; the head varying in colour from black with the anterior part testaceous to entirely testa-

ceous; the prothorax black, sometimes paler at the sides; the elytra black, with two flavo-testaceous fasciee

—one a little below the base, interrupted at the suture (formed by an oblique stripe on each elytron), the

other postmedian, transverse, uninterrupted ; the pygidium testaceous; the, pubescence partaking of the

ground-colour. Head strongly transverse, the eyes rather small; palpi testaceous, the last joint of the

maxillary pair elongate, moderately stout, scalene-triangular in both sexes, its apical side fully as long as

the inner side; antenne pitchy-brown with the basal joints testaceous, or entirely testaceous, very

short in both sexes, joints 3 and 4 narrow, short, subequal, 5-11 a little thickened, 5 considerably longer

and stouter than 4, 5-10 decreasing in length, 10 as broad as long in the female ; prothorax transverse ;

elyira short, subparallel in their basal half; beneath black, the last ventral segment often testaceous ;

pygidium elongate, very slender; legs partly testaceous, the hind femora piceous; the hind tibie with two

short oblique ridges, the first joint of the hind tarsi with one only, near the tip.

Length to end of the elytra 13-2, to tip of the pygidium 2-23, millim. (d 2.)

Hab. Norta America, Southern States12,—Mexico, Chilpancingo, Teapa (H. H.

Smith); Guatumaa, Capetillo, Zapote (Champion).

Eight specimens, agreeing fairly well with the imperfect descriptions of Leconte and

Smith. Of the same size and colour as M. xanthopyga, which also has very short

antenne in both sexes; but easily distinguishable from it by the ridges on the hind

tibiee being subequal and by the last joint of the maxillary palpi being very similarly

formed in the two sexes (in M. xanthopyga, 3 , this joint is hammer-shaped). If. beata

has similarly carinate hind legs; but it has the male maxillary palpi formed as in

M. xanthopyga. The Zapote specimen is smaller and narrower than the others.

68. Mordellistena crux. (Tab. XV. figg. 21; 21a, hind leg.)

Moderately elongate, narrow, subparallel, black; the head narrowly in front, the sides of the prothorax broadly

behind, a curved oblique stripe on each elytron some little distance below the base, connected near the

suture with a postmedian fascia, and also the extreme margin of the elytra, except at the base, flavo-

testaceous ; the pubescence partaking of the ground-colour. Head short and broad, the eyes moderately

large ; palpi testaceous; the last joint of the maxillary pair oblong-ovate, blunt at the apex; antenne

obscure testaceous with the basal joints paler, slender, filiform, moderately long, joints 3 and 4 narrow,

subequal, together not so long as the fifth, 5-11 a little stouter, 5-10 elongate, subequal, 11 longer than

10; prothorax transverse ; elytra moderately long, subparallel in their basal half; beneath black, the

ventral segments with their apical margins testaceous; pygidium elongate, slender ; legs in great part

testaceous, the hind femora piceous; the hind tibie with two very short ridges, the first joint of the hind

tarsi with one only, near the tip.

Length to end of the elytra 23, to tip of the pygidium 27, millim.

MORDELLISTENA. 347

Hab. GuateMaLa, Calderas, on the slope of the Volcan de Fuego 7000 feet

(Champion).

One example. Closely resembling the var. y of IZ mutabilis, from Chiriqui, but

differing from it in having two very short ridges only on the hind tibiz near the tip,

and one only on the first hind tarsal joint; the apical joint of the maxillary palpi is

more ovate, the thorax is transverse, the pygidium is a little shorter, &c. The black

colour is more extended on the elytra, and the yellow markings are very sharply defined.

The form of the palpi, the much longer antenne, and the more elongate shape distin-

guish it from MW. bicinctella. M. crua resembles the North-American MM. trifasciata

and its allies in colour, but the carine on the hind legs are formed as in MV. bicinctella.

69. Mordellistena beata. (Tab. XV. fig. 22, 3.)

Short, cuneiform, the head reddish-testaceous, the prothorax flavo-testaceous with a broad black median vitta

extending from the base to the apex, the scutellum and elytra black, the latter with a broad oblique flavo-

testaceous stripe extending from the shoulders towards the suture, but not reaching it, the pygidium

testaceous ; the elytra with a sharply defined yellowish-cinereous-pubescent fascia beyond the middle and

some similarly coloured pubescence at the base, the rest of the pubescence partaking of the ground-colour.

Head short and broad; palpi (3) testaceous, the last joint of the maxillary pair twice as broad as long,

hammer-shaped ; antennz as in VM. palpalis; pygidium very elongate, two and a half times the length

of the hypopygium ; beneath black, the last ventral segments testaceous ; legs testaceous, the hind femora

piceous ; the hind tibize with two very short ridges (and traces of a third) near the tip, the first joint of

the hind tarsi with one only.

Length to end of the elytra 2, to tip of the pygidium 24, millim. (¢.)

Hab. Mexico, Cuernavaca (H. H. Smith).

One male example. Very near I. palpalis, but with the elytral punctuation finer

and denser; the sides of the thorax broadly, and an oblique stripe extending from

the shoulders inwards, flavo-testaceous. As in I. palpalis, the postmedian fascia of

the elytra is formed entirely by the colour and arrangement of the pubescence; in

M. xanthopyga it is accompanied by a difference in the ground-colour.

70. Mordellistena perexigua.

Comparatively short, cuneiform, narrow, black, coarsely pubescent, the elytra with two broad cinereo-pubescent

fasciee—one before, the other beyond the middle,—the rest of the elytral pubescence blackish-brown, that

the last joint of the maxillary pair twice as broad as long, very stout, hammer-shaped; antenne ( ¢ )

pitchy-brown, very short, joints 3 and 4 slender, 4 slightly stouter than 3, 5-11 a little thickened, 5-7 as

broad as long, 8—10 transverse, 11 longer than 10; prothorax transverse; elytra narrowing from the

base; beneath black, the venter and the sides of the breast cinereo-pubescent ; pygidium elongate, more

than twice the length of the hypopygium; legs piceous, the anterior femora and tibiz testaceous ; the

hind tibiz with two very short ridges near the tip, the first joint of the hind tarsi with one only.

Length to end of the elytra 2, to tip of the pygidium 23, millim. (<¢.)

and pygidium black, the legs (the anterior pair excepted) piceous; the antenne pitchy-

brown, much shorter, and with joints 8-10 transverse. The pubescence is long and

coarse, and the punctuation is coarse also.

71. Mordellistena minutissima. (Tab. XV. figg. 23, ¢; 23¢, maxillary

palpus; 23 0, hind leg.)

Short, cuneiform, the head and prothorax flavo-testaccous, the scutellum and elytra black, the pygidium testa-

ceous; the elytra with two broad, not very distinct, transverse cinereo-pubescent fasciee—one before, the

prothorax excepted, the last ventral segment testaceous ; pygidium very long and slender, more than twice

the length of the hypopygium ; legs flavo-testaceous, the hind femora piceous ; the hind tibie and the

first joint of the hind tarsi with two very short faint ridges near the tip.

Length to end of the elytra 14-14, to tip of the pygidium 13-2, millim. (¢.) ©

Hab. GuateMata, near the city, San Geronimo (Champion).

Three male examples. Smaller than the smallest example of M. palpalis ; the head

and thorax entirely flavo-testaceous, the antenne shorter and more slender. ‘This and

M. pulicaria are perhaps the smallest species of the genus yet described.

72. Mordellistena palpalis. (Tab. XV. figs. 24,3; 24 a, maxillary palpus, 3;

24 6, maxillary palpus, 2 .)

Stout, cuneiform, black, the head reddish-testaceous, the pygidium reddish or testaceous, the elytra with two not

very distinct cinereo-pubescent fascisee—one post-basal, the other post-median,—the rest of the pubescence

rather sparse and partaking of the ground-colour ; the elytral punctuation coarse. Head broad and short,

the eyes rather small; palpi testaceous, the last joint of the maxillary pair usually darker at the tip, the’

latter more than twice as broad as long and somewhat hammer-shaped in the male, elongate-ovate with the

apex obliquely truncate in the female ; antenne very short in both sexes, testaceous, joints 3 and 4 about

Eight examples. This is one of a little group of species, all of which are of very

small size, and have the apical joint of the maxillary palpi very broad and somewhat

hammer-shaped in the male, the hind tibiee with two or three very short ridges near

the tip only, the antenne very short in both sexes, and the elytra spotted or with

cinereo-pubescent fascize. ‘The pubescence of the elytra is rather sparse and the punc-

tuation comparatively coarse. M. palpalis belongs to the subgenus Tolida, Muls., as

defined by Emery.

73. Mordellistena pulicaria,

Short, cuneiform, black, finely pubescent, the elytra with two cinereo-pubescent fasciee—one basal, the other

postmedian,—the rest of the pubescence partaking of the ground-colour. Head short and broad; palpi ( 2 )

fusco-testaceous, the last joint of the maxillary pair oblong-ovate with the apex obliquely truncate;

antennee ( 9 ) fusco-testaceous, very short, joints 3 and 4 narrow, subequal, 5-11 a little thickened, 5-10

as broad as long, 11 longer than 10; prothorax transverse; elytra short, gradually narrowing from the

base; beneath black, the sides of the breast in front and of the venter cinereo-pubescent ; pygidium mode-

rately long; legs piceous, the anterior pair obscure testaceous, the hind tibial spurs testaceous ; the hind

tibiee with two ridges towards the tip—the first obliquely extending across the outer face of the tibia, the

other short, subapical; the first joint of the hind tarsi with a single ridge.

Length to end of the elytra 14, to tip of the pygidium 13, millim. ( 9.)

Hab. GuateMata, Zapote (Champion).

Though we have but:a single female example of this little insect, I do not hesi-

tate to give ita name. It comes nearest to W/. perexiqua, but differs from that species

in its finer pubescence, smaller head, and shorter elytra, the latter with the anterior

fascia at, not below, the base. The pygidium is also shorter, and the first ridge on

the hind tibie extends across their outer face. ‘The species is of about the same size

and build as WV. minutissima.

74. Mordellistena fasciculata, (Tab. XV. figg. 25; 25a, maxillary palpus.)

Very elongate, narrow, subparallel, black, the sides of the prothorax narrowly and the pygidium reddish ; the

prothorax with the base narrowly and an indistinct line on either side of the disc, the scutellum, and

numerous small, transverse, partly confluent spots scattered irregularly all over the elytra golden-pubescent,

the rest of the pubescence on the prothorax and elytra black, that on the head yellowish, the pubescence

coarse and somewhat dense. Head rather small, the eyes not very large; palpi very elongate, testaceous,

the last joint of the maxillary pair elongate-triangular, moderately stout, its inner and apical sides about

equal in length and very much shorter. than the outer side, the latter slightly concave, the apical side

rounded; antenne obscure testaceous, very slender, filiform, moderately elongate, joint 3 narrow, short,

4 considerably longer than 3, 5 longer than 4 or 6, 5-11 elongate, 6-10 subequal, 11 longer than 10 ;

prothorax transverse, much wider than the head; elytra very elongate, more than four times the length

of the prothorax, subparallel in their basal half; beneath black, the apical margin of each ventral segment

testaceous ; pygidium elongate, slender, more than twice the length of the hypopygium ; legs testaceous,

the middle and hind femora, the hind tibiz in part, and the extreme tips of the tarsi piceous; the hind

tibie with a short subapical ridge only; the first joint of the hind tarsi with traces of several oblique

ridges.

Length to end of the elytra 3-4, to tip of the pygidium 33-43, millim.; breadth 3-1 millim.

Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith).

Two examples, probably females. This peculiar species has a subapical ridge only

to the hind tibie, and in this respect agrees with Mordella; but it evidently belongs

to Mordellistena, the following closely allied form being intermediate between it and

those species with the ridges on the hind legs not very sharply indicated. The larger

size, the very elongate elytra, and the long testaceous antenne distinguish it from

M. festiva, apart from the differences in the sculpture of the hind tibie and tarsi.

75. Mordellistena festiva. (Tab. XV. figg. 26,3; 26a, hind leg.)

Elongate, very narrow, parallel, the head (the eyes excepted), prothorax, antennex, and palpi clear testaceous,

the elytra black, each with a small obscure testaceous spot in the middle at the base, the pygidium reddish-

testaceous ; the elytra with numerous transverse, partly confluent, yellowish-cinereous-pubescent spots

scattered over the surface, these spots tending to form fascie, the scutellum with similarly coloured

pubescence, that on the rest of the surface partaking of the ground-colour. Head moderately large ;

palpi as in M. fasceculata; antenne moderately long, filiform, joints 3 and 4 short, subequal, 5~11 elon-

gate, a little thickened, 5-10 subequal, 5 nearly twice as long as 4; prothorax transverse; elytra elongate,

subparallel to beyond the middle; beneath black, the head, prothorax, front of the breast, and apex of

each ventral segment testaceous ; pygidium very long, slender; anterior and middle legs entirely flavo-

testaceous, the hind pair a little darker, the hind femora piceous; the hind tibize with a short subapical

ridge and indications of a faint carina along the dorsal edge; the first joint of the hind tarsi with three,

the second joint with two, very faint, oblique, parallel ridges.

Length to end of the elytra 3, to tip of the pygidium 4, millim.; breadth 1 millim. (¢.)

Hab. Mexico, Amula in Guerrero 6000 feet (H. H. Smith).

One male example. Closely allied to I. fasciculata, from which, apart from colour,

it differs by its relatively shorter elytra, rather stouter antenne, the fourth joint of

which is only about half the length of the fifth, and the more fasciate arrangement of the

pubescence. Viewed in certain lights, the hind tibiz seem to have a faint carina along

the dorsal edge. |

Fam. RHIPIDOPHORIDA.

Three genera only of this group are known to me as yet from Central America; two

of these, Emenadia and Rhipidophorus, are common to North and South America, but

the third, Pelecotomoides, does not extend north of the Mexican State of Vera Cruz.

It is probable that Toposcopus will eventually be found in Northern Mexico; it has the

eyes completely divided and the claws serrate. A good deal of diversity of opinion

exists amongst authors as to the application of the generic names in this family; the

Munich Catalogue is here followed.

PELECOTOMOIDES.

(1855); Lacordaire, Gen. Col. v. p. 620.

Pelecotomoides, Gemminger & Harold, Cat. vii. p. 2118.

This genus is chiefly confined to Tropical America and Australia. Gersticker in his

“ Monograph” enumerated thirteen species as belonging to it, but he appears to have

overlooked those described by Shuckard and Blanchard. ‘Four are now recorded from

PELECOTOMOIDES. 301

within our limits, but of all of them very insufficient material has been obtained. The

great variation in the colour of the pubescence in certain species has been noted by

Lacordaire ; and large series af most of them are required before the specific variation

can be properly understood. The males and females of two species only were known

to Gerstacker.

Our species may be tabulated thus :—

Eyes very large, coarsely granulated, approximate ; antennze with the four basal

joints simple (the fourth angularly produced within in the male). . . . . nubila.

Eyes smaller, more finely granulated, distant.

Antenne with the three basal joints simple . . . . . . . . . . « Uneata.

1. Pelecotomoides nubila. (Tab. XVI. figg.1,¢; 2, 24,9.)

Trigonodera nubila, Gerst. Rhipiph. Col. Fam. Disp. Syst. p. 4 (¢)’.

Hab. Mexico, Tehuantepec (Sallé); Nicaragua, Chontales (Belt); Panama, Bugaba

(Champion).—Pert !.

Five specimens—a pair from Tehuantepec, a female from Chontales, and a pair from

Bugaba,—agree so nearly with Gersticker’s description of P. nubila that there can be

little doubt they belong to his species. The eyes are very large, feebly emarginate,

coarsely granulated, and in both sexes only separated by a narrow raised line. The

antennee have their four basal joints simple; the second and the fourth joints are very

short in the male, a little longer in the female; joints 5-11 have each a very elongate

ramus in the male, and are very acutely serrate in the female. The Panama specimens

have the elytral pubescence; interrupted by ill-defined transverse or oblong patches

of a fuscous colour, the other examples being uniformly yellowish grey-pubescent.

Gersticker particularly notices the ‘‘fronte inter oculos lineari ” as characteristic of his

P. nubila; the male only of the species was known to him. Our specimens vary in

length from 6-11 millim.

2. Pelecotomoides lineata. (Tab. XVI. figg. 3, 3a, 2.)

Q. Moderately elongate, brown, the elytra darker, densely and finely punctured, thickly pubescent; the

pubescence on the head and prothorax golden or greyish-yellow, the prothorax with a well-defined median

vitta (narrowed before and behind), and in one specimen a small oblong spot at the sides about the middle,

brown-pubescent; the pubescence on the scutellum and elytra brown, the latter with a narrow, well-

defined, longitudinal stripe extending obliquely from a little below the base to the suture just before the

apex (and widening a little posteriorly) golden- or greyish-yellow-pubescent. Head small; the eyes widely

separated, deeply emarginate, finely granulated ; antenne pitchy-brown with the three basal joints reddish,

rather short, joints 1-3 narrow, 2 very short, 3 about twice as long as 2, subtriangular, 4-10 very strongly

serrate; prothorax convex, about as long as broad, with the sides rapidly converging from the base, almost

straight, a little rounded in front only, the hind angles acute, the basal lobe shallowly emarginate in the

middle; elytra moderately long, gradually narrowing from the base, rounded at the apex; lege and under

surface pitchy-brown or reddish, the latter densely pubescent.

Length 77-10 millim.

Hab. Mexico, Jalapa (Hoge).

Two female examples. P. lineata differs from all the species described by Gerstacker

in having the three basal joints only of the antenne simple.

3. Pelecotomoides bivittata.

Pelecotomoides bivittata, Chevr. in litt.

Q. Closely resembling the same sex of P. lineata, but differing as follows:—The antennex entirely reddish,

with the five basal joints simple—2 and 3 very short, 4 and 5 wider, about as broad as long, 5 a little

wider than 4,—6-10 very strongly serrate, 6 twice as wide as 5; the brownish-pubescent median vitta of

the prothorax more dilated at the middle and less sharply defined ; the longitudinal golden-pubescent vitta

on each elytron wider and less oblique, extending inwards in front and reaching the base, the brown pubes- _

cence on the rest of the surface with intermixed golden hairs.

Length 83 millim.

Hab. Mrxico, Cordova (Salié).

One female example. Closely resembling the same sex of P. lineata, but differing

from it by the small non-serrate fourth and fifth joints of the antenne. This specimen

has the seventh antennal joint on one side abnormally formed, it being biserrate.

P. bivittata agrees in some respects with the description of P. bistriata (Gerst.), from

Peru; but it cannot be satisfactorily identified therewith. As in P. lineata, the elytral

stripes are confluent at the suture a little before the apex.

A second specimen from Cordova (Sad/é) has the upper surface very densely and

uniformly greyish-yellow-pubescent; it may be a variety of P. bivittata, or it may be

referable to P. helva, Perty (the figure of which it closely resembles), but as the

antenne are broken off it is impossible to identify it. P. helva (2), according to

Gerstacker, has the five basal joints simple, the third joint twice as long as the second.

4. Pelecotomoides nebulosa. (‘Tab. XVI. figg. 4, 40,9.)

Q. Moderately elongate, rather broad, brown or blackish-brown, thickly pubescent, densely and finely punc-

tured; the pubescence yellowish-grey, more or less mottled with fuscous (the dark hairs showing a

tendency to form a median patch on the prothorax, and transverse, irregular, partly confluent patches on

the elytra). Head small; the eyes widely separated, deeply emarginate, finely granulated; antennz rather

short, black or piceous, with the five basal joints more or less rufous, joints 2, 4, and 5 very short, 3 about

twice as long as 2, 5 acutely produced within, 6-10 very strongly serrate, 6 nearly twice as long and twice as

wide as 5; prothorax convex, about as long as broad, with the sides a little rounded and rapidly converging

from the base, the hind angles acutely produced behind, the basal lobe emarginate in the middle ; elytra

moderately long, gradually narrowed from the base, a little flattened on the disc anteriorly, obtuse at the

apex, the apices slightly divergent and somewhat angular; beneath brown or reddish-brown, densely

cinereo-pubescent, the apical ventral segment with some brown pubescence at the tip; legs pitchy-brown

or reddish, the tibial spurs black.

Length 74-11 millim. .

Hab. Panama, Taboga I. (Champion).—Cotomsia (coll. F. Bates).

PELECOTOMOIDES.—EMENADIA. 353

Three examples, all females. A specimen of the same sex, from Brazil, in Mr. F.

Bates’s collection (from that of Dejean), labelled Trigonodera nebulosa, is no doubt a

variety of the same species ; it has the pubescence of the upper surface golden-brown,

with the base of the thorax and some markings at the base of the elytra, and a few

small spots on the disc of the latter, whitish. The description of Zrigonodera

pallipes, Gerst., based upon a male example from Brazil, nearly agrees with the

present insect as regards the form of the antenne; but Gerstiicker says “articulo

primo oblongo-triquetro, sequentibus quatuor transversis,” a definition not applicable

to P. nebulosa ( ¢ ).

This genus is represented in most parts of the world, and several of its members are

extremely variable in colour. Some of the American species are very widely distri-

buted, and out of the eight enumerated by Dr. Horn in his excellent monograph of

the species of the United States (op. cit. pp. 121-125), no less than six occur within

our limits; of these latter one only was noticed by Gerstiicker as from Mexico. Four

other species are also recorded here from Mexico or Central America, two of which are

described as new. ‘The important structural characters to be found in the form of the

prosternum and in the anterior and hind tarsi are noticed by Dr. Horn; they seem to

_have been entirely overlooked by Gerstacker. The name Macrosiagon, Hentz, though

it is ten years earlier than that of Castelnau, has not been adopted by authors. The

Central-American species may be tabulated thus :—

between this and the tip deeply excavate . . . . . . . . . . . Species 1.

One female specimen from Durango, agreeing very closely with Dr..Horn’s descrip-

tion?. It is black, with the abdomen red and the elytra with a broad pale yellow fascia

immediately below the base; the median lobe of the thorax is strongly raised just

before the base, and the space between this and the tip is transversely hollowed; the

second joint of the hind tarsi is simple, and slightly shorter than the third.

A Guatemalan example of this insect has been kindly communicated by Dr. Horn.

The species is apparently not uncommon in Mexico and Guatemala, whence we have

received upwards of twenty specimens. The elytra are described! as “brownish,

gradually becoming black at the base, a small arcuate space one-fourth from the

humerus pale luteous:” two-thirds of the specimens received have the elytra entirely

black, the others having them coloured as described by Dr. Horn. The thorax has a

large, very deep, triangular fovea on either side of the disc before the base, the space

between the foveee appearing to be longitudinally raised, this elevation extending down

the median lobe to the tip, which is transversely notched. The second joint of the

hind tarsi is shorter than the third, and broadly dilated. The anterior coxe are

- separated for half their length by a prolongation of the prosternum. Our specimens

vary from 74 to 134 millim. in length. . bifoveata was described from a single male

example.

3. Emenadia excavata, (Tab. XVI. figg. 7,9; 8,2, var.)

Elongate, rather narrow, moderately shining; the head and prothorax black, pitchy-red, or rufous; the elytra

testaceous or flavo-testaceous with the base, the sutural and lateral margins, and a sublateral stripe—

extending from the apex to a short distance below the base, and widening anteriorly (in one example

extending to the base)—more or less black or piceous, these markings abbreviated posteriorly in light-

coloured examples, but always distinct, the base sometimes rufous; antenns in the male testaceous or

reddish with the rami fuscous or black, in the female black with the two basal joints reddish-testaceous’;

beneath varying in colour from black to ferruginous, the metasternal epimera and the hind coxe flavous

behind; legs varying in colour from black to rufous with the knees and the tips of the tarsi piceous, the

claws yellow. Head finely and sparsely punctured anteriorly, the vertex almost smooth and very much

raised, the front moderately convex, the epistoma truncate, the occiput confusedly punctured, slightly

concave ; prothorax about one-third longer than broad, rapidly narrowing from the base, the sides sinuate

behind the middle, the hind angles sharp but not prolonged backwards, the surface thickly and somewhat

coarsely (in some specimens quite finely) punctured, the disc with a broad and rather deep longitudinal

groove on either side extending from the base to about the middle, the intermediate space strongly convex,

the basal lobe equilaterally-triangular, obsoletely carinate or slightly raised, and usually (but not always)

transversely notched at the tip, the tip obtuse; elytra long, sharply pointed at the apex, becoming gradually

dehiscent from a little below the base, punctured like the prothorax, but with a deep longitudinal channel

on the disc of each almost impunctate, this channel accompanied externally by a more or less elevated

ridge or carina; beneath sparsely, the legs thickly, punctured; anterior coxz separated for about half

their length by a narrow prolongation of the prosternum, contiguous behind ; second joint of the hind tarsi

broadly flattened, a little shorter than the third joint; anterior tarsi in the male with joints 2-4 thickly

pubescent beneath.

Of this species, the commonest of the genus in Mexico, we have received forty-one

examples: out of this number three only are of the male sex. Though very variable as

regards the colour of the head, thorax, under surface, and legs, E. excavata is unusually

constant in the colour and markings of the elytra, these latter only varying in the

predominance of the yellow or of the black, the markings being always distinct.

E. excavata is nearest allied to E. bifoveata (Horn), from which it differs, apart from

the colour and markings of the elytra, by the shallower, longer, and much less abrupt

depression on either side of the disc of the thorax behind ;

shape, and less dehiscent and less acuminate elytra. ‘The punctuation of the head and

thorax is rather variable; the vertex is usually almost smooth, at most sparsely punc-

the intermediate space much less convex; the vertex a little flattened in front; the

antenne, the extreme tips of the rami excepted, brownish-yellow; the legs reddish-

spot, and the apex black ; in the female the elytra are black and the abdomen is red.

The median lobe of the thorax is transversely notched at the tip. The second joint of

the hind tarsi is broadly dilated, shorter than the third. |

This extremely variable species seems to have been described under no less than

fifteen different names.

We have received about twenty specimens of this extremely variable species, all but

three of which are from Mexico: of .these, six are black; two are black, with the

thorax rufous; two are black, with the head and thorax rufous; two are black, with

the disc of the elytra (and the sides of the thorax also in one specimen) partly rufous ;

five have the thorax and elytra flavo-testaceous or stramineous, the former broadly

marked with black on the anterior half of the disc and the latter with the sutural and

lateral margins and the base black; one (from Chiriqui) has the thorax and elytra

entirely stramineous ; two are rufous, with the base or apex of the elytra black. The

anterior coxee are narrowly separated by the prosternum ; the head is almost smooth,

with the vertex only moderately raised ; the second joint of the hind tarsi is a little

widened, not or very little more than half the length of the third.

_ The representatives in the Sallé collection are separated into five species. Iam

indebted to Dr. Horn for an example of #. limbata for comparison. We figure four

We have received four female specimens of an Emenadia from Mexico agreeing very

well with Gerstacker’s description of H. discicollis1, and there is also a Mexican

example of the same species in the British Museum. In three of these the elytra are

black with a slight bluish tint in certain lights, and the thorax is rufous or reddish-

testaceous with the disc to a variable extent black; one (from Sturm’s collection) is

reddish-testaceous above and beneath, with the apices of the elytra black ; one (in the

EMENADIA.—RHIPIDOPHORUS. 309

British Museum) is reddish-testaceous, with the base of the elytra ‘very broadly and also

a large apical patch black.

E. mutilata (Gerst.), from Colombia, is stated? by its author to differ from E. disci-

collis by its smaller size and by having the head and prothorax entirely rufous ; it is,

no doubt, a variety of #. discicollis. EH. 4-maculata (Gerst.), from Cuba, is rufous,

with the anterior half of the ‘thorax and the base and apex of the elytra black.

E, vitraci, Fleut. & Sallé, from Guadaloupe, of which I have examined two examples—

a male (agreeing precisely in colour with H..4-maculata, Gerst.) kindly communicated

by M. Fleutiaux and a female in the British Museum,—belongs to the same species.

E. melanoptera, Chevr., from Porto Rico, agrees with EH. mutilata (Gerst.) in colour.

The species in all its varieties may be easily separated from the other Central-American

forms by its comparatively short, obliquely truncate elytra, the inner apical angles of

which are rounded, very fine punctuation, and shining surface; the head is smooth and

very shining, and has the vertex very little raised; the outer lobes of the maxille are

greatly elongated; the anterior cox are narrowly separated by the prosternum ; the

second joint of the hind tarsi is dilated, not more than half the length of the third. As

in several other members of the genus, the colour is exceedingly variable, and of no

value whatever as a specific character.

This widely distributed and exceedingly interesting genus is well represented in

North and Central America, but from south of the Isthmus of Panama a single species

only, &. rugosus (Waterh.), has been recorded as yet. Leconte in his monograph (op.

cit.) enumerated eleven species from the United States, and mentions two others from

North America as being unidentified by him ; but it is more than probable that several

of these are not really distinct. Seven are here enumerated from Central America. The

species of this genus are exceedingly rare in collections, and the majority of them have

been described from single examples only. The European R. suddipterus, Bosc, is

parasitic upon Halictus sexcinctus, Latr., according to Fabre; and it is probable that

the other members of the genus are of similar parasitic habits. In two of the species

here described the abdomen apparently has a sharp carina along the centre of the

dorsal segments, but this may be partly due to contraction after death. In one group

of species the first joint of the hind tarsi is short, stout, and very much compressed ;

sae

viewed laterally this joint appears to be very obliquely truncate at the apex, owing to

the deep apical emargination. In one species, R. rev, the anterior coxe (and the

middle coxe also to a less extent) havea hairy process on the inner side towards the base.

The abdomen in the European R. subdipterus differs in colour in the two sexes; in

R. tuberculatus and R. niger, however, the only species of which we possess males and

females, there is little or no variation in this respect.

One male example. This is perhaps the finest species of the genus yet described.

The antenne (including the rami) and legs are very stout. The dorsal segments

of the abdomen (the first excepted) are very sharply carinate down the middle. The

anterior coxe have a stout hairy process on the inner side, this process being of the

same yellow colour as the femur, while the coxa itself is black. The first joint of the

hind tarsi is very much compressed and raised, the apex (viewed laterally) very

oblique.

One female example. A large species, readily separable from its allies by the smooth

and shining thorax and abdomen; the latter is reddish-yellow, with the apical segment

black. In its smooth thorax &c. this species agrees with the description of R. popenot

the outer margin) about the middle, the apical margins reddish; the antennz fusco-testaceous ; the

abdomen reddish-yellow, with the base and the extreme apex stained with piceous ; the legs black, with

the tibial spurs and the claws reddish-yellow. Head closely and rather coarsely punctured, the front

concave; the vertex strongly transversely raised in the middle, and thickly clothed with erect fuscous

hairs; antenne with the rami very long and slender; prothorax canaliculate in its median third,

to the apex, above and beneath with widely scattered fine punctures, the first two dorsal segments almost

smooth ; legs stout, the tibize broad and compressed ; the first joint of the hind tarsi short, not longer than

the apical one, very stout, strongly compressed and much raised, very deeply emarginate at the apex

above, the second joint also stout and compressed, more than twice as long as the third ; wings suffused

with yellow throughout, the basal half of the costa reddish-brown, a patch on the costa beyond this

smoky.

Hab. Mexico, Atoyac in Vera Cruz (Schumann).

One female and two male examples. This species differs from all the others here

described by the strongly raised, very stout, blunt tubercle on the vertex in the male

sex, this tubercle being replaced in the female by an angular elevation. ‘The abdomen

is thickly and finely punctured. The angular elevation on the vertex of the female

will easily distinguish 2. tuberculatus from the same sex of the closely allied 2. simplex ;

the latter, moreover, has an angular prominence beneath the point of insertion of

each antenna, of which there is no trace in &, tuberculatus.

stout ; prothorax densely, finely, and shallowly pan etined, an interrupted median line, an irregular space

on either side of it about the middle, and a much smaller one near the base, smooth ; elytra shining, with

scattered shallow fine punctures, the base more closely and coarsely punctate ; sidetien above and beneath

The specimen described by Mr. Waterhouse ! is evidently a female, and we have an

example from Orizaba agreeing with it. A male from Panzos, from which the above

description is taken, no doubt belongs to the same species, the head, as in the same

sex of R. tuberculatus, having a prominent tubercle on the vertex. In the females of |

both species this tubercle is replaced by an obtuse elevation. ‘The tubercle (or median

carina) on the vertex in the male is compressed and not nearly so stout as in R. tubercu-

latus: viewed from behind it appears to be conical.

very broad, closely and finely punctured, the front flattened ; the vertex with a small, compressed, acute

tubercle in the middle, and numerous long erect hairs; antenne with the rami very long, slender, and

slightly curled; prothorax closely and finely punctured, with a smooth median line, the disc obliquely

depressed on either side towards the base, the depression limited anteriorly by a short, oblique, smooth

ridge ; elytra shining, finely punctured at the base, the apical half smooth; abdomen closely and finely

punctured, the first two dorsal segments smoother; legs rather slender, the tibie moderately compressed ;

Fam. MELOIDA.

Two Monographs of the Mexican species of this family have been published by

Dr. E. Dugés:—(1) La Naturaleza, i. pp. 100 et seg. (1870); (2) An. Mus. Michoacano,

li, p. 34 et seg. (1889).

Subfam. MELOINA.

The subfamily Meloine is represented within our limits by ten species, belonging to

four genera. Cysteodemus is one of the most remarkable forms of Meloide, and, like

Henous and Megetra, is peculiar to the American continent,

MELOE.

Meloe, Linnzus, Syst. Nat. 10th edit. p. 419 (1758) & 12th edit. i. 2, p. 679,

Michoacano, ii. p. 35 (1889).

Four species of this genus occur within our limits; one only appears to have been

known to Dugés from Mexico, whence three are now recorded. America north of

Mexico contains fourteen representatives, the species becoming more numerous north-

wards. Meloe is a characteristic genus of the temperate zone, and in Mexico and

Central America its members are confined to the elevated regions of the interior. It

apparently does not extend south of Costa Rica, as we have not a single representative

of the genus from the State of Panama; the South-American forms probably all

belong to Pseudomeloe, Fairm. & Germain. WM. levis, Leach (=cordillere, Chevr.,

and barranci, Dugés), has the mandibles tridentate within, and it forms the type of the

genus Treiodous, Dugés. This character is probably common to many other species

with simple antenne, ¢.g. of Mulsant’s subgenus Meloe; M. cicatricosus, Leach,

agrees with MV. Jevis in this respect. As is well known, some of the species of Meloe,

more particularly those of the If. proscarabeus-group, vary to such an extent that it is

MELOE. 365

almost impossible to separate them in a satisfactory manner. The cedeagus of the

male scarcely differs in form in MZ. levis and M. dugesi: the central sheath is furnished

on the lower side with two long, curved, sharp, compressed teeth directed backwards;

on the upper side in Mf. levis there is a very short curved tooth (also directed back-

wards) near the tip, this short tooth being obsolete in M. dugesi. The Mexican and

Central-American species all have the head and thorax smooth, or, at most, very finely

and sparsely punctured. |

Motschulsky, in the fifth volume of his “ Etudes,” enumerates certain Coleoptera

found by Wagner in Nicaragua; and amongst them he mentions a Meloe “ voisine par

la taille, la couleur, et la forme des antennes de I. proscarabeus, mais presque lisse,

je la nomme WM. tropicus” 1. Long afterwards, he gives some further particulars about

a male of the same species and names it WM. seulpticornis. He describes? “the head,

thorax, and abdomen as almost smooth; the elytra very finely rugulose and a little

longer than the head and thorax united ; the thorax elongate, distinctly angular at the

sides anteriorly, and with an impressed median line; the colour as deep as in U/. pro-

scarabeus, but with a greenish reflection ; the intermediate joints of the antenne very

strongly dilated.” A male Meloe of very large size, from Costa Rica, labelled WM. tro-

picus, Motsch., in Sallé’s collection, agrees very well with this description ; and I also

refer two females from Guatemala to the same species. It closely resembles the N.-

American I. americanus, Leach (the type of which is contained in the British Museum),

and M. angusticollis, Say, but differs from both these species by the much smoother head,

thorax, and elytra. The thorax is considerably longer than broad, with the sides

somewhat angularly dilated anteriorly and sinuate or compressed behind this; it has a

smooth, more or less impressed median line and a faint depression on either side of it

on the disc about the middle; the surface bears a few very widely scattered exceedingly

minute punctures, these being chiefly placed near the anterior margin. The names

MW. tropicus and M. sculpticornis, Motsch., are omitted by Escherich (Deutsche ent.

Zeit. 1889, pp. 333-335) in his list of species of Meloe added since the e pubheption of

the Munich Catalogue.

little before the middle to the base, the base emarginate in the centre, thé disc usually with a faintly

Thirty-four specimens, the majority of which are from Villa Lerdo and. Jalapa.

Closely allied to WM. tropicus, and perhaps only a variety of that species. Some

examples are black, smooth, and quite opaque. Others, equally dull black, have the

thorax very finely and distinctly punctured: such specimens closely resemble the

North-American MM. strigulosus, Mann.; they have the thorax, however, always more

narrowed behind than in that species (of which I have three Californian examples

before me for comparison). MW. dugest differs from MM. tropicus by its black or

violaceous-black colour, opaque surface, and less elongate thorax, the sides of the latter

Jess angularly dilated anteriorly and less sinuate behind. The female is exceedingly —

like I. levis, but may be easily known-from it by the form of the antenne. The

thorax varies in width : in three males from Jalapa it is very narrow, and in one male

from Cordova it is, on the contrary, very broad.

This species appears to have been quite overlooked by Dugés, after whom [ have.

much pleasure in naming it. In the British Museum there is a single female example

of a Meloe, labelled “ Mexico (Glennie),” which is apparently an extreme form of

M. dugesi; from which it differs. by its stouter antenne (their penultimate joints not

much enger than broad), and very broad head and thorax. Segue

This is a common and very widely distributed species in the elevated regions of

Central America, extending northwards into the United States and southwards to

Costa Rica. MV. levis may be chiefly known by its almost impunctate, dull surface,

and rather elongate thorax; the elytra in some examples are longitudinally wrinkled’;

the antenne are simple in both sexes, distinctly thickened towards the tip, and more

elongate in the male than in the female. A few specimens of the male sex from

Capulalpam, Peras, and Toluca have the antenne more slender than usual, but Iam

unable to separate them from WV. levis. MV. cordillerw, Chevr., does not differ in any

way from MM. levis, Leach, the type of which is contained in the British Museum.

M. sublevis, Lec., of which I have a male specimen from Colorado before me, merely

has the elytra more distinctly rugulose than in typical M. levis; several of our

Mexican examples exhibit this peculiarity, JI have examined upwards of one hundred

examples, and there can be no doubt that all the above names refer to one and the

same species. .

. Antenne long and comparatively slender in both sexes, very little longer in the male,

not thickened towards the tip. se

4. Meloe gracilicornis. (Tab. XVII. fig. 4, 2.)

Entirely black, opaque, smooth (the elytra included), impunctate. Antenne elongate and comparatively

slender in both sexes, a little longer in the male than in the female, straight, not thickening outwardly

in either sex, joints 3-7 about equal in length, 8-10 slightly longer, 11 nearly twice as long as 10, of

equal thickness to beyond the middle and then rapidly narrowing to the apex, its apex somewhat pointed;

prothorax about as long as broad, narrowing behind, the base rather deeply emarginate in the middle,

the disc with a smooth central line ; abdomen above and beneath smovth, impunctate; sixth ventral seg-

ment triangularly emarginate in the male.

Length 164-36 millim. (¢ 9.)

Three examples—a pair from Omilteme and a male from Juquila. M. gracilicornis

is very closely allied to MU. levis, but may easily be distinguished from it by the slender

antenne in both’ sexes, this difference being especially noticeable in the female sex: in

the female of WM. levis these organs are much shorter than in the male, and distinctly

thickened towards the apex. In Sallé’s collection there are four male specimens

labelled with the MS. name I. gracilicornis, Sallé: one of these, from Juquila, I refer

to this species, the other three (though they have the antenne unusually slender), from

Capulalpam and Peras, I treat as an extreme form of WM. levis. 7

We have received five females and two males of this species. The female only was

known to Dugés. H. cardui is closely allied to H. confertus, but differs from it by

the finer and shallower punctuation of the head and thorax, the interspaces between

the punctures not being granular; the elytra are also less rugosely punctured ; the

thorax is less convex; the head has a more or less distinct, smooth, impressed median

line extending from the epistoma to the occiput; the third joint of the antenne is not

so long as the following two joints united; and the pubescence is brown, with a few

intermixed ashy hairs. The male has the elytra contiguous for about two-thirds of

their length, and subconnate towards the base; in the same sex of H. confertus they

are contiguous nearly to the apex, and in some specimens connate throughout. In

this, as in the other species of the genus, the anterior femora and tibie have a silky-

pubescent patch on the inner side about the middle, this character being also present

in some genera of the group Cantharides, e. g. Macrobasis, Epicauta, &c. The males

of H. cardui have the side-pieces of the meso- and metasternum covered by the

inflexed portion of the elytra, these pieces being more or less exposed in the female.

. Two specimens of ‘this insect were captured by Hoge at Misantla. It differs from

H. confertus and H. cardui by its smoother and almost glabrous upper surface. The

elytra are very minutely and sparsely, the head and prothorax more closely and distinctly,

punctured, Fresh specimens appear to be clothed with a very fine scattered pubescence,

which is easily abraded. H. mexicanus is nearly allied to H. sublevis.(Horn), from

California. |

This genus includes two species from the Southern United States and Northern

Mexico. According to von Harold (Col. Hefte, xiii. p. 105), the genus Pseudomeloe,

Fairm. & Germain, which contains numerous species from the South-American Andes,

is synonymous with Megetra; but this is probably incorrect, as Pseudomeloe is particu-

larly stated to have the two portions of each tarsal claw equal. In Megetra the

anterior tibize are densely clothed on the inner side with fine silky pubescence.

This group contains two very anomalous insects, one (Hornia minutipennis, Riley)

from the United States, and the other (Leonea rileyi, Dugés) from Mexico; both

appear to be parasitic on the Hymenopterous genus Anthophora. Leonia seems chiefly

to differ from Hornia by the tarsal claws being provided on the underside with “a long,

straight, acute spine, which attains three-fourths of the length of the claw;” we have

not received an example of it. Hornia is referred by Leconte and Horn (Class. Col.

Two species are confounded by authors under the name of H. maculata (Swed.); their

H. maculata we have only received three examples from within our limits—a male

from Morelia, a female from Chontales, and a male from Bugaba. The H. maculata

of Dugés, and of Leconte and Horn, is no doubt referable to the species described

below under the name of H. auriculata. H. apicalis, Perty, from Brazil, is apparently

nothing but a variety of H. maculata (Swed.), from which it differs in having the base

and apex only of the elytra black. A variety with the elytra entirely black occurs in

Colombia. The head in H. maculata is flattened in front, or has a broad shallow

median depression; the antenne are comparatively short in both sexes; the thorax is

very broad, in some male specimens wider in front than at the base, strongly transverse,

with the obtuse anterior angles raised, not deflexed ; the first joint of the hind tarsi is

shorter than the following joints united. The spots on the elytra are usually smaller

than in H. auriculata: in the latter the antemedian juxta-sutural spot is extended to

the suture, so as to form with the one on the opposite elytron a common, transverse,

large black patch.

Reddish-testaceous, shining ; the mandibles, eyes, palpi, antenns, and legs, the base of the femora excepted,

black ; the elytra with the base and apex and two interrupted fascia (formed by four large spots on each

elytron) black. The head almost smooth—in the male exceedingly large, with the temples greatly

swollen on either side, so as to leave a very deep median groove, the convex portion forming ‘a

more or less prominent ear-like lateral projection, which is deeply excavate behind for the reception

of the anterior angle of the prothorax—in the female much smaller, with the temples only moderately

swollen on either side, and the median groove shallow; the antenne in both sexes much more elongate

than in H. maculata, with the fourth joint longer than the second and third joints united; the prothorax

in the male much narrower than in H. maculata, not so wide anteriorly, less transverse, with the

anterior angles deflexed and considerably produced in front, the transverse basal depression shallower,

the deep transverse depression on either side near the anterior margin almost or quite obsolete, the surface

smooth or minutely and sparsely punctured,—in the female not nearly so wide as in the same sex of

HI. maculata, and very much narrower at the apex than at the base; the first joint of the hind tarsi much

more elongate than in H. maculata, as long as the following joints united; the sixth ventral segment cleft

Specimens of this species were chiefly obtained by me in the open verandahs of

houses; and on more than one occasion I have observed the insect crawling on the

wood-work in the close vicinity of the nests of a large blue wasp, these nests being

commonly found in such places. It is probable, therefore, that H. auriculata really

preys upon this wasp, and not upon Xylocopa.

The insect from Barbados mentioned by Landsdown Guilding is evidently referable to

H. auriculata. I have not seen an example of H. auriculata from south of Costa Rica.

NEMOGNATHA. 3738

This genus contains numerous representatives in the New World, the majority of

which are from the United States, Mexico, or Guatemala, the species becoming fewer in

number southwards. Some of its members vary greatly in colour, more particularly as

regards the elytra—from flavous or fulvous to entirely black (WV. lurida, N. nigripes,

&c.), or with a black vitta (NV. piezata, N. tarasca, &c.); others, WV. cwruleipennis,

Perty (=versicolor, Chevr.), are equally variable as regards the colour of the head, —

thorax, and underside. Leconte, in his second Monograph of the North-American

Nemognathe 1, sinks seven out of the twenty-five described species as varieties. The

elongated outer lobe of the maxillz is the only character by which this genus can be

separated from Zonitis, and this character fails in one of the new species here

described, VV. ephippiata. In a series of eight examples of this insect, six have the

lobe a little longer than the head, one has it very much abbreviated, and in another

it is not longer than in typical Zonitis*. In N. cwruleipennis, Perty, it is fully as long

as the body.

The Central-American species may be tabulated thus :—

The different forms of this species occur together, upon flowers on the open savanas,

in various places in Mexico, in Guatemala, and in South America. The head, thorax,

violaceous or ceruleous, metallic. The varieties with the head and thorax black (y and 6)

occur commonly at Matamoros Izucar; but they are not mentioned by Chevrolat or

Dugés. Numerous South-American examples of the forms described by Lucas under

the names of NV. bicolor and NV. abdominalis are before me; they do not differ in any

way from those from Central America. In the male of WN. ceruleipennis the fifth

the under surface, legs, scutellum, and elytra black. NV. decipiens is stated by its

author? to be a variety of WV. lurida; if this is the case, Leconte’s description ® of the

posterior tibial spurs of NV. decipiens is inaccurate. In WV. lurida the outer spur of the

posterior tibic is exceedingly stout, broad, and truncate at the apex, and the inner one

is short and small. Amongst the large number of specimens collected by Hoge at

Villa Lerdo, there are several with the elytra entirely piceous. The general colour

is fulvous.

the under surface, tibiee, and tarsi more or less infuscate. The vittate form agrees well

with typical V. piezata from Texas; the unicolorous ones with Leconte’s var. ¢exana,

of which I also have Texan examples before me.

In the male of this species the fourth and fifth ventral segments are deeply excavate

along the middle, the concave portion being densely clothed with fine pubescence; the

sixth segment, as usual, is cleft down the middle, and broadly and deeply excavate

in the centre. ‘The spurs of the hind tibie are moderately stout and obtuse, the outer

one a little stouter than the other. According to Leconte, WV. dicolor, NV. discolor, and

N. palliata, Lec., are probably nothing more than varieties of WV. piezata. The only

specimen I have seen of JV. bicolor, a male, has the elytra more rugosely punctured than

in WV. piezata.

5. Nemognatha brevicollis. (Tab. XVII. fig. 11.)

Elongate, parallel, depressed ; above and beneath, the legs, palpi, and antennz black, the prothorax and the

extreme base of the elytra (including the humeri), and in one specimen a transverse patch between the

eyes, flavo- or reddish-testaceous ; clothed with very fine pubescence, that on the prothorax semierect and

partaking of the ground-colour. Head triangular, not much prolonged in front, thickly and not very finely

punctured; the mandibles and palpi comparatively short ; the outer lobe of the maxille a little shorter

than the antenn, not half the length of the body; the antenne comparatively short, rather stout,

filiform, the second joint extremely short, not nearly half the length of the third; prothorax a little wider

than the head, nearly twice as broad as long, narrowed behind, the hind angles almost rounded, the surface

finely and somewhat thickly punctured; elytra long and parallel, densely rugulose, with traces of three

faint raised lines extending from the base to about one-fourth from the apex; beneath shining, sparsely

punctured ; the spurs of the hind tibize slender, subequal.

Length 84-104 millim. (9.)

Hab. Mexico, Matamoros Izucar (Sallé, Hoge).

Two examples. Closely allied to the North-American WV. nemorensis, Hentz; but

differing from it by the pale thoracic pubescence, the thorax itself wider and still more

transverse; the elytra black, with the extreme base coloured like the thorax, densely

rugulose (not densely and minutely punctured). The second joint of the antenna is

extremely short. The elytra in certain lights have a violaceous lustre. The specimens

I have seen of V. nemorensis have the head broader than the thorax.

6. Nemognatha foveifrons. (Tab. XVII. fig. 12.)

Moderately elongate, rather broad, somewhat depressed, flavo-luteous, the eyes, the antenne, and the tips of

the mandibles and palpi black; very finely pubescent, the pubescence very short and partaking of the

ground-colour, the head and prothorax shining, the elytra opaque; the legs testaceous, with the knees and

the tarsi piceous. Head short, triangular, deeply transversely depressed between the eyes, thickly and

finely punctured, the mandibles comparatively short, the labrum transverse, the palpi moderately long ;

the outer lobe of the maxille nearly half the length of the body; antenn elongate, filiform, the second

joint about half the length of the third; prothorax wider than the head, strongly transverse, a little

constricted at the sides behind, and dilated at the base, the anterior angles broadly rounded, the hind

angles prominent, the surface sparsely and finely punctured, the disc shallowly transversely depressed

‘before the apex, an oblique depression on either side externally at the base; scutellum sparsely punc-

tured; elytra moderately long, parallel, flattened on the disc, minutely but not very densely granulate,

each elytron with four, faint, slightly impressed lines extending from the base nearly to the apex; beneath

testaceous, sparsely and finely punctured; the spurs of the hind tibie slender, equal.

Length 93 millim. (2.)

Hab. Mexico (coll. F. Bates), Yolos (Sallé); Guatemata (Mus. Brit.).

Four examples, one of the type and three of the variety, all in a bad state of

preservation, and their sex not ascertained. In its long, erect, dark pubescence,

strongly transverse thorax, and dark underside and legs this species approaches the

N orth-American WN. scutellaris, Lee. ; it differs, however, from the two Californian

examples of that insect before me by its more finely punctured upper surface, the punc-

tures on the elytra much more closely placed, the smoother abdomen, &c. NV. nigripennis,

Lec., from New Mexico and California, is an allied species, but apparently has a less.

strongly transverse thorax.

Both forms of WV. nigripes were obtained at Yolos. The specimen in Mr. F. Bates’s

collection, from that of Dejean, is labelled with the name I have adopted. 7

- 8. Nemognatha ephippiata. (Tab. XVII. fig. 13.)

Moderately elongate,’ flattened above, a little widened posteriorly, opaque, finely and densely pubescent; the

head testaceous, with two oblong spots between the eyes and an oblique mark on either side behind these:

extending to the occiput, black, these markings in some examples coalescent, largely extended, and

forming two broad sinuous stripes; the prothorax testaceous or ochraceous, with a broad, slightly

oblique, black vitta on either side ‘of the disc extending from the apex nearly to the base; the scutellum

varying in colour from ochraceous to. piceous; the elytra ochraceous, with a fascia below the base, more

: or less excised on its lower edge, and extending upwards at the suture and laterally to the base (so as to

enclose a large rounded spot on each elytron), and the apical third or more, black ; the antenna, palpi,

tips of the mandibles, and legs black, the base of the femora sometimes testaceous; the under surface

varying in colour from piceous to testaceous. Head transverse, densely, rugosely punctured, with a

_ the outer lobe of the maxille a little longer than the head, in some specimens abbreviated and not

longer than in Zonitis; antenne long and filiform, the second joint scarcely shorter than the third ;

prothorax of the same width as the head, broader than long, subcampanulate, the sides broadly rounded

_ in front and slightly sinuate behind, the hind angles rather prominent, the surface densely, rugosely

punctured, transversely depressed on either side anteriorly, and with a smooth, impressed, median line;

elytra narrowed a little towards the base, separately rounded at the apex, very densely punetured,

Fight examples—seven of the type and one of the variety, the latter from Teapa.

This peculiar species closely resembles Zonitis nigromaculata, Dugés, but it is less

elongate, the head and thorax are shorter, and the antenne are filiform ; the ochraceous

basal spot on each elytron is more oblong in the Zonitis, and placed at the shoulders

instead of at the middle. ‘The variation in the length of the outer lobe of the maxilla

in WV. ephippiata is remarkable, and the species connects the genus Nemognatha with

Zonitis.

Found in abundance by Hége in Chihuahua. This species may be easily known by

its uniform pale greenish-yellow colour, shining surface, and glabrous thorax and elytra ;

the thorax is smooth and as long as wide, and the elytra are sparsely, very coarsely,

irregularly punctured, with two fine lines on the disc showing through from beneath.

- The head is obliquely and rapidly narrowed in front of the eyes. WV. immaculata is

recorded as having been found in plenty upon thistle-flowers.

10. Nemognatha tarasca. (T'ab. XVII. fig. 14, vittate form.)

Nemognatha tarasca, Dugés, An. Mus. Michoacan, ii. p. 112 dis".

Flavo-testaceous or testaceous, shining, each elytron usually with a broad piceous or brownish vitta on the

disc extending from the base to the apex—sometimes extended and leaving only the sutural and lateral

margins pale, sometimes entirely obliterated; the antenne, the tips of the mandibles, the palpi, and eyes,

and sometimes the labrum in part, piceous or black; the legs testaceous or flavo-testaceous, the tibiz and

tarsi usually more or less infuscate ; beneath testaceous, the venter sometimes piceous; the prothorax

and elytra glabrous, the head and the under surface very finely pubescent. Head rather coarsely punc-

tured, thickly so in some examples, more sparsely so in others; the mandibles considerably elongated and

the labrum large ; the outer lobe of the maxille about as long as the head; palpi slender, elongate ;

antennex elongate, filiform, the second joint a little shorter than the third; prothorax convex, subquadrate,

nearly or quite as long as broad, usually a little dilated at the base, rounded at the sides in front, with a

few very widely scattered punctures, and sometimes with indications of a short impressed median line

behind the middle; scutellum depressed, thickly punctured anteriorly ; elytra convex, subparallel, each

with three raised lines or coste extending from the base nearly to the apex, the two inner ones usually

very sharply defined, for the rest coarsely and rather sparsely punctured; the outer spur of the hind

tibie stouter than the inner one, spoon-shaped ; beneath with the ventral surface in the male dull, and

densely and finely punctured, in the female shining and sparsely punctate ; sixth ventral segment in the

male cleft down the middle, the fifth unimpressed.

Var. a. Larger ; the elytra pale gréenish-yellow ; the legs, the tarsi and knees excepted, flavous.

Length 7-12 millim. (¢ 9.)

Hab. Mexico, Morelia (Leon 1), Chilpancingo (H. H. Smith), Etla, Tuxtla, Yucatan

(Sallé), Temax in North Yucatan (Gaumer); GuatemaLa, San Gerénimo (Champion) ;

Nicaragua, Chontales (Belt); Panama, near the city (Champion).

Notwithstanding various discrepancies from the description (which is apparently

based on a single specimen), I have very little doubt that I have correctly identified

Dugés’ species. It is advisable, however, to give a renewed description from the large

number of specimens received, the species being a very variable one.

The species is common in Yucatan, but is apparently rare elsewhere. About three-

fourths of the Yucatan examples, and the one from Chontales also, have a broad

piceous or brownish vitta on each elytron; in the other examples the elytra, as stated in

Dugés’ description, are entirely brownish-yellow. Of the var. « we have three specimens,

one from Etla and a pair from San Gerénimo. Two examples—one from Chilpan-

cingo and one from Panama—have the head and thorax more thickly punctured, but

they are connected with the type by intermediate gradations. It is probable that our

Yucatan specimens are somewhat discoloured and that the ground-colour of the elytra

is pale greenish-yellow, as in var. « NV. tarasca is closely allied to WV. immaculata,

Say, and has the thorax and elytra glabrous as in that species ; it differs from it, how-

ever, by the three well-marked raised lines or coste of the elytra, the latter more

closely and not so coarsely punctured. The thorax is very sparsely but quite distinctly

punctured, instead of being almost impunctate as in NV. immaculata, and the head is

more prolonged in front than in that species. NV. punctipennis, Lec., from Arizona,

and WV. dunniana (Casey), from Texas, are also allied forms; the former has the head

more prolonged in front*, and the latter has the elytra more coarsely and more sparsely

punctured. Labelled V. marginata, Pilate, in the Sallé collection.

extending northwards to near the Mexican frontier. WV. zonitotdes agrees very néarly

with Leconte’s description of V. cribricollis (=porosa and fuscipennis, Lec. (Trans. Am.

Ent. Soc. viii. p. 215), but it has the head black. This species has the head consider-

ably prolonged in front and very long mandibles, and in this respect (as Leconte

remarks of W. cribricollis) resembles Gnathium. The colour of the thorax, elytra, and

legs is variable. The specimens from Coahuila and Guatemala have the elytra more

closely and less coarsely punctured than in most of those from the intervening localities,

but they are connected by intermediate forms. The length (with the head fully

extended) varies from 44-9 millim. Labelled WV. egena, Dej., in Mr. F. Bates’s

We have received ten examples of this species—seven from Mexico, two from

Guatemala, and one from Costa Rica. This insect has the thorax longer than broad,

considerably narrowed in front, and constricted before the apex, the disc transversely

depressed anteriorly and with a well-marked median channel, the surface densely and

finely punctured. The elytra are very densely and finely punctured, with the inter-

Spaces somewhat granular. The antenne are elongate and filiform, black. The upper

surface is opaque, flavous or flavo-luteous, and clothed with fine, short, golden pubes-

cence. The outer lobe of the maxille is longer than the head, the head itself

prolonged in front, and the mandibles are elongate (as in WV. zonitoides). The legs are

variable in colour. In two or three examples the head has a narrow transverse space

between the eyes infuscate. .

M. Sallé has recently forwarded me an example of this species. It is closely allied

Found in abundance by Herr Hége at Jalapa. Dugés’ description ' appears to have

been made from a greasy or discoloured specimen.. This insect much resembles the

var. 3 of Nemognatha ceruleipennis, Perty, but it has the elytra dull instead of shining.

The head (the eyes excepted), thorax, and under surface, the femora, and the base of

the elytra are metallic blue or violaceous (more obscure in greasy examples), opaque.

The head is triangular, broad, short; the thorax is strongly transverse, narrowed and

broadly rounded at the sides anteriorly, and has a deep transverse depression on either

side in front and a deep median groove behind, the surface with fine, widely scattered

known by its long and narrow head, campanulate, sanguineous thorax, and depressed,

broad, dull black, granulated elytra. The head, scutellum, and under surface vary in

colour. In some of the specimens with the head flavous, the head itself is longer,

narrower, and more parallel than usual. The second joint of the antenne varies in

length, it being considerably shorter than the third in some specimens. The thorax

often has the punctures confluent, and when this is the case the surface is opaque, not

shining. The different varieties are connected by intermediate forms.

This insect agrees in some respects with Dugés’s description of Z. flavicollis; the

colour of the thorax, however, is not yellow, but pale sanguineous; and the head is

narrow and subparallel, not broadly triangular. We figure two specimens, one from

Duenas and one from Chontales.

7. Zonitis lateritia, (Tab. XVII. fig. 22.)

Elongate, finely pubescent, above and beneath reddish-testaceous, opaque; the eyes, the tips of the mandibles,

the palpi, antenne, tibie, and tarsi black. Head comparatively small, narrow, prolonged in front, with

the labrum rather longer than broad and the mandibles elongate, closely and finely punctured ; the eyes

transverse, rather small; antenuz setaceous, very long and slender, joint 1 stout, 2 and 3 more slender,

equal, 4-11 decreasing in thickness, 4-7 almost equal in length, very much longer than 3, 8-11 very

slender, 11 a little longer than 10; prothorax much wider than the head, rather longer than broad, sub-

campanulate, considerably narrowed in front, subparallel at the sides behind, depressed on either side of

the middle anteriorly, closely and finely punctured, with a well-marked smooth median line (raised before

the middle and depressed behind) ; scutellum densely, minutely punctured; elytra elongate, widening a

little posteriorly, very densely and finely punctured ; beneath more sparsely punctured, shining; hind

tibial spurs stout, spoon-shaped, subequal.

Length 13 millim.

Hab. Nicaracua, Chontales (Belt).

One example. The small, narrow, anteriorly prolonged head, small eyes, uniform

reddish-testaceous body, and black antenne distinguish this species at a glance from

Z. megalops.

8. Zonitis nigromaculata. (Tab. XVII. figg. 23; 23 a, maxillaand maxillary

palpus. )

Zonitis nigromaculata, Dugés, An. Mus. Michoacano, ii. p. 111 dis’.

Hab. Mexico, Atoyac (Flohr 1), Tuxtla (Sallé).

We have received four examples of this very distinct species, two from Atoyac and

two from Tuxtla. It closely resembles Nemognatha ephippiata, but is more elongate

and has a longer and narrower head, and very differently formed antenne. The head

and thorax have a black vitta on either side ; tbe elytra have a very broad fascia below

the base, extending broadly upwards along the suture to the base, and the apical third

black ; the rest of the upper surface is tawny-yellow. ‘The antenne have their five

basal joints stout, and the following ones gradually tapering to the apex ; joints 1-3 are

rather short, subequal, 4-6 each nearly one half longer than 3, 11 very slender. The

underside is black ; the coxe and trochanters, and usually the base of the femora also,

are testaceous. The elytra are a little widened posteriorly, and this character gives the

insect a Lyciform appearance. The fifth ventral segment is divided down the middle

in the male. Z. nigromaculata much resembles some species of the Longicorn genus

Pteroplatus.

9. Zonitis fulva. (Tab. XVII. figg. 24, 25, varr.)

Tab. Mexico, Atoyac ([lohr1), Cordova (Sallé), Cerro de Plumas (Hége) ; GUATE-

MALA, Coban (Conradt).

We have not received an example of the form of this insect described by Dugeés'.

The following are, I have no doubt, colour-varieties of the same species :—

Var. a. The head with the sides and a median vitta extending forwards as far as the middle of the eyes (this

marking obsolete in one example), and a rather broad line along the prothorax and scutellum in con-

tinuation of this, piceous or black ; the elytra entirely reddish-yellow ; the underside and legs black.

Var. B. The head, prothorax, and scutellum with a median vitta, asin a. The elytra black, with the sides to

about one third from the base rather broadly reddish-yellow ; or reddish-yellow, with the apical half or

more, and two or three stripes extending from it forwards, black—the stripe nearest the suture extending

to the base, widened anteriorly, and there confluent with the one on the opposite elytron. The underside

and legs black.

The following are the chief characters mentioned by Dugés ! :-—“ 'Tawny-yellow, with

the antenne, the apices of the tibie, the tarsi, and sometimes the sides of the abdomen

black; the head triangular; the antenne setaceous—joints 1-3 triangular and sub-

equal, 4 longer than 3, 5-10 equal in length but decreasing in thickness, 11 sub-

cylindrical; the thorax long, campanulate, with a well-marked dorsal groove, the

surface very densely punctured ; the elytra separately rounded at the apex, pubescent.”

‘The insect has a very Lyciform appearance. The elytral pubescence is dense, and of

a brick-red colour, the surface beneath being yellowish. The antenne are strongly

setaceous, the joints from the fifth rapidly diminishing in thickness. ‘Lhe entire upper

surface is very densely and finely punctured.

Both the varietal forms were obtained at Cordova.

10. Zonitis megalops. (ab. XVII. fig. 26, ¢.)

Elongate, parallel, opaque, finely pubescent; brownish-testaceous, the head in front, an ill-defined median vitta

on the prothorax, and a similar mark on the scutellum, reddish-brown, the eyes black, the tips of the

mandibles and the palpi piceous, the base of the elytra slightly infuscate (perhaps owing to discoloration) ;

the antenne piceous, with the base of each joint very narrowly testaceous; beneath pitchy-brown ; the

legs testaceous, with the middle of the femora, the apices of the tibia, and the tarsal joints (except at the

base) stained with fuscous. Head as wide as the prothorax, rounded at the sides behind, moderately

prolonged anteriorly, densely and finely punctured, more coarsely so in front; the labrum about as broad

as long, the mandibles rather elongate; the eyes very large, deeply emarginate, alm<st contiguous beneath

and rather narrowly separated above ; last joint of the maxillary palpi elongate, subcylindrical, truncate

at the tip; antenne nearly as long as the body, very slender, subfiliform, joints 2 aud 3 subequal, 4 nearly

twice as long as 3, 4-6 subequal, 7-11 a little thinner and rather shorter; prothorax longer than broad,

flattened on the disc, subcampanulate, gradually narrowing from the middle to the apex, subparallel at

the sides behind, densely, finely, confluently punctured, and with an impressed median line; scutellum

densely, minutely punctured ; elytra elongate, parallel, very densely and finely punctured; beneath more

shining, closely and finely punctured; hind tibial spurs rather stout, spoon-shaped, subequal; sixth

ventral segment very deeply triangularly emarginate in the male.

Length 124 millim. (<¢.)

Hab. Guatemata, Volcan de Atitlan 3000 foet (Champion).

One male specimen, apparently immature. A species readily recognizable by its

exceedingly large eyes, very long and slender antenne, elongate, subcampanuliform

thorax, and very dense, fine punctuation. ‘The upper surface is obscure testaceous,

opaque, and on the thorax and scutellum there is a reddish-brown median vitta. The

antenne and tarsi have an annulated appearance, the extreme base of their articulations

being pale testaceous. ‘The antenne are very slender, and become slightly thinner

towards the tip.

To judge from the description, Z. megalops approaches Z. longicornis, Horn, from

Illinois, in some of its characters.

An exclusively American genus, and particularly rich in species in the tropical

regions of the Southern continent; it extends southwards to Chili and the Argentine

Republic and northwards to the Southern United States, and is also represented in the

Antilles. Haag in his Monograph (Stett. ent. Zeit. 1879, pp. 249 e¢ seq.) enumerates

seventy-five species as belonging to it, thirteen of which occur within our limits; of

these latter, however, three are not represented in the collections before me, and the

locality is in two cases doubtful. Three species only have been recorded from north of

the Mexican frontier: one of these, 7. guadrimaculatus (Fabr.), is almost certain to be

found eventually in Mexico ; the other two are known to be Mexican. Some of the

species, 7. sexguttatus &c., are extremely variable as regards the colour and markings

of the elytra. The males in this genus have the sixth ventral segment deeply emargi-

nate; and in some cases, 7’. fulvus, 7. frontalis, &c., the front tarsi dilated, with their

large species, of a uniform dull cyaneous or greenish-cyaneous colour. Z. pectoralis

is very closely allied to 7. crassus (Klug), from Brazil, but differs from it by the denser

and finer punctuation of the upper surface and by the cyaneous hind coxe.

Haag®. This author has separated the Mexican and Central-American forms from

T. sexguttatus under the collective name of 7. proteus; but in this [am unable to

-followhim. The form described by Olivier and Klug has three rounded spots on each

—elytron, and some of our Mexican examples (one of which has been determined by Haag

himself as 7. sexguttatus) agree exactly in this respect with Brazilian ones.

In addition to the five varieties named by Haag, I have to notice two others :-—

Var. a. humboldti, Haag (=ochraceoguttatus, Dugés).—Size large; the elytra black, with three large orange

spots (2, 1), the posterior one broad.—Mexico, Surinam, Brazil.

Var. 3. biguttatus, Haag.—Smaller; the elytra with the two anterior spots partly or entirely connected, and

the posterior one large and more or less excised, these markings forming two angulated fascie. (Figg. 1, 2.)

——Mexico, Honduras, Nicaragua, Chiriqui.

Var. y. sanguinolentus, Haag. Large; the elytra black, with two orange or rufo-fulvous fasciee extending com-

pletely across, the anterior one more or less angulated, the posterior one broad. (Fig. 3.)—-Mexico.

Var. 6. Large; the elytra black, with two narrow rufo-fulvous fascie, and the sides, base, and apex narrowly

margined with the same colour. (Fig. 4.)—Guatemala.

Var. e. sellatus, Haag.—Large ; the elytra orange, with the base and apex black. (Fig. 5.)--Mexico.:

Var. Z. Large; the elytra red, with a scutellar patch, two spots placed transversely on the disc beyond the

middle, a spot at the inner apical angle, and the apex itself, narrowly, black. (Fig. 6.)-—-Guatemala.

Var. n. centromaculatus, Haag. Large; the elytra orange, with a rounded spot below the scutellum black.—

Loc.?

Several of these varieties occur together at the same places; and though the typical

form is common to Mexico and Tropical South America, I have not seen examples of

it from intermediate localities. South-American specimens seem to vary very little.

3. Tetraonyx octomaculatus.

This species, the type of the genus, has not been identified by modern writers. It

is black, each elytron with four blood-red spots—two at the base (one median, in the

form of a narrow band, the other humeral, triangular) and two at the middle (placed

transversely). Latreille states that the insect was found upon the Liquidambar '.

T. octomaculatus is an ally of T. sexguttatus (Oliv.); but it can scarcely be a variety

of it.

* The locality mentioned by Latreille is “ Xalapa, New Spain”; Castelnau gives Mexico, but this requires

confirmation, there being several places of this name in America.

example of it in Mr. F. Bates’s collection. This insect is black above and beneath ;

the elytra yellow or luteous-yellow, with eleven black spots of variable size arranged

thus—five on each elytron, placed transversely, 2, 2 (sometimes coalescent), 1, and one

at the suture below the scutellum.

In Mr. F. Bates’s collection there is a Mexican specimen of a Tetraonyx agreeing

perfectly with Klug’s excellent figure of 7. dimaculatus; and this specimen has been

so named by Haag. IT. bimaculatus chiefly differs from 7’. maculatus by having the

basal black spot of the elytra extending to the humeri, and the transverse flavous space

behind this spot broader; the head is black. The basal joint of the anterior tarsi is

very stout, and dilated on the inner side, in the male. TZ. guadrimaculatus (Fabr.),

from the Southern States and the Antilles, is an allied species; it has the thorax

closely punctured.

We have received nine specimens of a Tetraonyx agreeing very well with Haag’s

definition of 7. maculatus, Casteln. A small species, of a flavous or flavo-testaceous

colour; the elytra each with two very large black spots—one basal, not quite reaching

the suture and more or less-excised near the shoulders in front, the other apical, the

latter confluent with the one on the opposite elytron; the antenne, the apices of the

femora, the tibie, and tarsi black; the underside reddish-testaceous. ‘The head is

sometimes partly brownish, and the thorax often has a piceous or brownish patch, or

two small spots placed transversely, on the middle of the disc. Haag appears to have

examined some of Sallé’s Mexican and Nicaraguan examples; but the only locality

mentioned by him ? is Brazil.

In Sallé’s collection the specimens with the thorax immaculate are labelled 7’. macu-

latus and those with the thorax spotted 7. maculicollis. 'The basal joint of the anterior

tarsi is slightly widened in the male.

(Sallé, Dugés*°, Hoge).

A common species in Mexico, extending over the northern frontier into the United

States and southwards into Guatemala. The variety femoralis has been received from

two localities in company with the typical form, and I have not the slightest doubt that

it is conspecific with it. Haag mentions* two other varieties :—(1) ‘‘ Capite nigro-

lineato, thorace nigro-bimaculato, scutello apice nigro, femoribus anticis rufomaculatis ” ;

(2) ‘*Capite nigro, post oculos rufomaculato; thorace bimaculato; scutello nigro.”

In the male the anterior tarsi are dilated, and the basal joint is angularly produced

within. 7. frontalis has much the facies of a large Pyrochroa. It may be easily distin-

guished from 7. fulvus by the head being black in front, and by the more densely

punctured opaque upper surface.

A single species only of this remarkable genus is known, peculiar to New Mexico

connate with it. |

An allied genus, Phodaga, Lec., containing a single species, P. alticeps, Lec., occurs

in Arizona; it will probably be found eventually in Northern Mexico.

Nine species are known of this genus, all from the Southern United States, chiefly

from Southern California. One of these crosses the Mexican boundary into Coahuila.

A single species is now added from Western Mexico. Calospasta is closely allied to

Kupompha, but differs from it by the vertex being much less raised. The lower portion

of the tarsal claws is a little shorter than the upper and connate with it. C. sulcifrons

resembles Eupompha in having the three basal joints of the anterior tarsi smooth and

greatly swollen in the male, but these joints are not grooved above as in FE. fissiceps :

this character, however, is present in the Californian C. histrionica, Horn. The genus

Tegrodera is a close ally of Calospasta, and the single species belonging to it will

probably be found eventually in Northern Mexico; it occurs in Lower California.

rugulosely punctured ; beneath and the legs closely and finely punctured, the metasternum smoother ; outer

spur of the hind tibie very broad, subtruncate at the tip, the inner one slender, acute.

CALOSPASTA.—MACROBASIS, 395

One male and two female examples of this remarkably distinct species have been

received from Mr. H. H. Smith. It is one of the most interesting of the Mexican

species of Meloide. The elytra are comparatively broad and parallel, and flattened on

the disc. The upper and under surfaces are very sparsely and finely pubescent.

Apterospasta, Leconte, loc. cit.

This genus is confined to the New World, and ranges from Canada to Guiana *, its

headquarters being in the Southern United States and the highlands of Mexico. From

north of Mexico fifteen species are known, five of which extend into our region, whence

fourteen are now recorded. Of this number two only occur south of Mexico. Macrobasis,

as Dr. Horn remarks, is only separable from Epicauta by the relatively longer second

joint of the antenne. The males of most of the species, as in some picauta, exhibit

_ remarkable characters in the form of the basal joints of the antenne and in the first

joint of the anterior tarsi. MV. curvicornis (Haag) (antennalis, Dugés), and WM. labialis,

Dugés, both from Mexico, belong to Epicauta as here understood.

Antenne dissimilar in the two sexes: the basal joint elongated (in some

species exceedingly so) or distorted in the male.

Joints 2-11 more or less elongate, 2 in some species thickened and very

Hab. Muxtco } (Sallé, ex coll. Sturm), Tupataro (Dugés? *), Guanajuato (Salle).

We have received two examples of this species, both males. The basal joint of the

antenne in this sex is moderately elongate, strongly sinuate, broadly and angularly

dilated on the inner side about the middle, and concave between this and the apex, the

latter truncate; the second joint is articulated to the first at the inner apical angle, and

is about half the length of the first; the third and fourth joints are short, subequal.

The anterior tibie have two spurs. The basal joint of the anterior tarsi is elongate

and quite normal, and considerably longer than the second.

Lytia fumosa, Germ., from Brazil, is an Epicauta.

2. Macrobasis distorta. (Tab. XVIII. figg. 16, ¢; 164, antenna, d .)

Elongate, parallel, sparsely and finely pubescent ; the head, prothorax, and underside testaceous or ferruginous,

sometimes in part piceous, the labrum usually paler in colour; the elytra luteous or fusco-luteous; the

legs testaceous or reddish-testaceous, with the knees, tibia, and tarsi usually darker; the elytra with the

sutural and lateral margins very narrowly and a fine median line extending from the base nearly to the

apex more densely clothed with paler or whitish pubescence, and sometimes with a spot on either side of

the scutellum at the base and a short streak on the humeri brown-pubescent, the rest of the pubescence

of the upper surface .yellowish-cinereous. Head moderately large, closely and finely punctured, with a

fine, sharply-defined, median line; antennz setaceous, black, the two basal joints in the male obscure

ferruginous ; prothorax narrower than the head, rather longer than bro ad, rounded at the sides anteriorly,

parallel behind, closely and finely punctured, with a fine, smooth, impressed median line; elytra long and

parallel ; beneath closely and finely punctured.

3g. Antenne with the basal joint nearly as long as joints 2-5 united, very stout and much flattened,

sinuous beyond the middle, broadly and angularly widened on the inner side at about one-third from the

apex, and deeply emarginate between this and the tip; joint 2 stout, flattened-cylindrical, slightly longer

than 3 and 4 united; joints 3-11 slender, decreasing in thickness, 3 shorter than 4; joints 1 and 2

shining, sparsely punctured, 3-11 opaque, densely and very finely punctate. Anterior tibiz with a single

spur. Anterior tarsi with the basal joint scarcely dilated, concave and almost smooth beneath, fully as

long as the second. Sixth ventral segment triangularly emarginate.

A pair from Nicaragua and three females from Mexico. In the greatly distorted

basal joint of the male antenna this species approaches VM. fumosa, from which it may

easily be distinguished by its more elongate shape, fine pubescence, and different colour,

and also by the single spur to the anterior tibie and the concave basal joint of the

anterior tarsi in the male. I. forticornis (Haag) is a similarly coloured allied form ;

but, to judge from the description, it has a much less angularly dilated basal joint—

Hab. Nortu America, Arizona !.—Mexico, Ventanas in Durango (Hége).

Dr. Horn’s description !, taken from a single male, from Arizona, nearly agrees with

a specimen of the same sex from Durango. The Durango male has the basal joint of

the antenne sinuous in its apical half, and excavate on the inner side beyond the

middle: the Arizona male is described! as having “the basal joint arcuate, gradually

wider from base, not contorted at apex.” As there are some other slight discrepancies,

I have thought it advisable to give a description of the Durango insect.

6. Macrobasis disparilis. (Tab. XVIII. figg. 18,3; 184, antenna, g .)

Elongate, narrow, parallel, black; the head, the flanks, the basal and apical margins, and sometimes a line on

the middle of the disc of the prothorax, the scutellum, the suture, the apical and lateral margins of

the elytra very narrowly, and a small spot at the middle of the base of each, the under surface, and legs,

cinereo-pubescent, the rest of the pubescence black or blackish-brown, sparse, and fine. Head moderately

large, closely and finely punctured, finely canaliculate in the middle, the epistoma separated from the front

by a deep groove; antenne slender, setaceous, black ; prothorax narrower than the head, about as long as

broad, the sides rounded anteriorly, parallel behind, and slightly widened at the base, the disc triangularly

depressed in the middle behind and with a well-marked median groove, the surface closely and finely

punctured; elytra very long and parallel, wider than the head, sparsely, minutely punctate; beneath

closely punctured; legs black.

3. Antenne with the basal joint exceedingly elongate, nearly reaching the base of the prothorax, and about

equalling joints 3-9 united, flattened and moderately stout, gradually thickening outwardly, and abruptly

sinuous in its apical third ; the second joint equally stout, flattened-cylindrical, slightly curved, as long as

joints 8-5 united, and not half the length of 1; joints 3-11 slender, moderately elongate, gradually

becoming thinner outwardly, subequal in length; joints 1 and 2 very sparsely, the others densely

punctured. Maxillary palpi flavous. Anterior tibie with a single spur, sinuous, Anterior tarsi with

the first joint partly flavous, flattened and sinuous, much shorter than the second, above and beneath

shining and almost glabrous, concave on the underside and at the base on the upperside. Sixth ventral

segment feebly emarginate.

9. Antenne slender from the base; joint 1 not equalling 2 and 3 united, 2 one-half longer than 3, 3-11

(voll. Haag *, Sallé, Conradt), Guatemala city (Rodriguez), Chacoj (Champion); Costa

Rica, Caché (Rogers).

This is the commonest species of Macrobasis within our limits, and ranges as far

south as Costa Rica. It was found in numbers by Herr Hoge at Chilpancingo. An

elongate, narrow species, varying greatly in the colour of the pubescence—from

cinereous to yellowish—and in the colour of the elytra—from piceous to testaceous.

The tarsi are piceous or black, the femora and tibie usually in great part testaceous.

The male has the basal joint of the antenne broadly flattened and slightly curved,

unemarginate on the inner side before the apex, and as long as joints 2-6 united, its

upper face sometimes grooved along the middle; the second joint flattened-cylindrical,

narrower, nearly one-third the length of the first and a little longer than the next two

joints together; joints 3-11 slender, 3 a little shorter than 4; joints 1 and 2 are

subglabrous, and almost smooth, the following ones densely rugose and pubescent.

The anterior tibiz in this sex have a single spur, and the basal joint of the anterior

tarsi is flattened and sinuous, and almost smooth. The basal joint of the male

antenna varies in width, it being considerably wider in some specimens than in others ;

in these in which it is widest (particularly in two from Guatemala) the median groove

is well defined. J. candezi is a dark form, and UM. pallida probably a light one, of

M. diversicornis. M. linearis, Lec., from Texas, is an allied species; it differs from

M. diversicornis in the relative length of the basal joints of the male antenna.

Found in numbers by Mr. Becker. Specimens of both sexes are before me.

M. beckeri agrees with M. diversicornis in the form of the antenne and anterior

tarsi in the male; but differs from that species in the finer, darker, and sparser

pubescence of the upper surface. The sides and front of the head, the occiput, and

the sides, base, and apex of the thorax, and the suture very narrowly, are cinereo-

pubescent, the rest of the pubescence being brown. All our specimens are more or

less abraded and discoloured.

10. Macrobasis humeralis.

Macrobasis humeralis, Dugés, An. Mus. Michoacano, i. p. 58°.

Hab. Mexico, Tepic (Flohr *).

We have apparently not received an example of this species, both sexes of which are

described by Dugés. “The antenne of the male are filiform, their first joint longer

than the head, and equal to joints 2-4 united, the second joint longer than the third,

and about one half as long as the first, joints 3-10 subequal, 1 and 2 shining. The

head and thorax are black, the elytra ferruginous. The pubescence is greyish-yellow ;

the elytra with a spot on either side of the scutellum and a streak on the humeral

callus blackish-pubescent.” The form of the anterior tarsi of the male is not mentioned.

11. Macrobasis tenuicornis. (Tab. XVIII. figg. 21,3; 21a, antenna, ¢ .)

Elongate, black, above and beneath rather densely cinereo-pubescent, the elytra with a small spot at the base

on either side of the scutellum and a small patch on the humeri blackish- or brown-pubescent ; the legs

cinereo-pubescent, the tarsi in great part and the tips of the femora and tibize brown-pubescent. Head

moderately large, very closely and finely punctured, with a fine median line, the latter ferruginous

anteriorly, the palpi pitchy-brown; antennx black, very slender, setaceous, the basal joints very little

thickened in the male; prothorax nearly as wide as the head, as long as broad, rounded at the sides

anteriorly, parallel behind, closely and finely punctured, and with a fine median line; elytra elongate,

much wider than the prothorax. .

3. Antennz with the first joint long and slender, extending to the base of the head, and about as long as

joints 2-4 united, not sinuate or emarginate on the inner side before the tip; joint 2 very little stouter

than 3, and fully one-half longer than it; joints 3-11 elongate, subequal in length; joints 1 and 2 thickly,

the others densely, punctured. Anterior tibia with a single spur. Anterior tarsi with the first joint

slightly longer than the second, not dilated, concave and smooth at the base beneath. Sixth ventral

segment feebly emarginate.

Length 124-144 millim. (¢ 9.)

Hab. Mexico, Chilpancingo (fH. H. Smith).

Two males—one from Chilpancingo, the other from an unknown locality; the latter

is contained in Mr. F. Bates’s collection. ‘This species differs from its allies in the

very long and slender basal joint of the male antenna, this joint being unemarginate on

the inner side before the tip; the second joint is quite slender, and one-half longer than

the third. I. tenuicornis approaches M. tenuis and M. diversicornis, but differs from

both in the form of the male antenna. J. unicolor (Kirby) has two spurs to the male

anterior tibia, and I. immaculata (Say) a very much shorter basal joint to the male

antenna. J. tenuicornis agrees very nearly in its male characters with M. humeralis,

Dugés; but there are considerable discrepancies in colour and other particulars, and it

cannot be satisfactorily identified with that species.

Leconte’s description ! (and apparently Dr. Horn’s also?) was made from a single male

example of unusually large size and somewhat pallid colour. Dugés describes and

figures both sexes4, from specimens found in a house at Guanajuato. I. ochrea

differs from all its allies in the short antenne, joints 2-11 being obconic, and 2 a little

shorter than 8. In the male the basal joint of the antenne is nearly one-third of their

entire length, the first joint of the anterior tarsi is broad, concave above, very much

shorter than the second, and obliquely produced within, and the last ventral segment

is emarginate. The elytra are uniformly testaceous; the head and thorax vary in

colour from piceous to testaceous. This species might equally well be placed in

Epicauta, the second antennal joint being slightly shorter than the third in both sexes.

Dr. Horn remarks* that the wings in this species are usually very small and

rudimentary, and that specimens occasionally occur in which they are fully developed.

The six examples, including both sexes, received by us from Mexico all have fully-

developed wings. A large black species, the thorax with a fringe of cinereous hair

along the base and apex, the rest of the pubescence of the upper surface (and that

of the under surface also in great part) black. The basal joint of the antenne is very

similarly formed in both sexes, and about as long as the following two joints united,

the second joint being a little shorter than the third; the anterior tibie have two

spurs in the male.

14. Macrobasis megacephala. (Tab. XVIII. figg. 24,3; 24a, antenna, ¢ .)

Elongate, black, finely and rather densely pubescent ; the pubescence on the head, the scutellum, and the apical

margin of the elytra cinereous, that on the rest of the elytra blackish-brown; the prothorax cinereo-

pubescent, with a large oblong patch on either side of the middle of the disc brown-pubescent; the

pubescence on the under surface cinereous, the ventral segments each with a transverse band in the

middle extending completely across blackish-pubescent. Head very large and convex, densely and finely

punctured, with a fine, smooth median line, which anteriorly is of a ferruginous colour, the anterior part

of the epistoma and the palpi flavous, the labrum deeply emarginate; antenne black or piceous, brownish

towards the base, slender, setaceous ; prothorax much narrower than the head, as long as broad, the sides

converging and rounded anteriorly and parallel behind, the disc triangularly depressed in the middle

before the base, and with a faint median line, the surface very closely punctured; elytra only a little

broader than the head, elongate, closely and shallowly punctured.

3g. Antenne with the basal joint slender, thickening a little outwardly, twice as long as the second, unemar-

ginate on the inner side before the apex; the second joint shorter than the third, equal to the fourth;

joints 5-11 equal in length. Anterior tibiee with two spurs. Anterior tarsi with the basal joint normal,

elongate, nearly as long as joints 2 and 3 united. Sixth ventral segment subtruncate.

Length 194-21 millim. (<¢.)

Hab. Mexico, Monclova in Coahuila (Dr. Palmer).

Two male examples, both worn. Closely allied to, and perhaps an extreme form of,

M. segmentata, from which it may be known by the larger and more convex head, and

the different colour of the pubescence of the head, thorax, and under surface. The

antenne are more slender in the male, but otherwise they are formed as in I. segmentata.

The following species is placed by Dugés in Epicauta, but it belongs to Macrobasis,

the second joint of the antenne (<¢ ) being comparatively elongate and as long as the

third. The insect was omitted from the table of species of Macrobasis, antea, p. 395.

Hab. Mexico (coll. F. Bates), State of Vera Cruz! 2, Orizaba (Sailé).

The female of this insect is so like the same sex of M. albida that I incorrectly

identified two specimens of it with that species, anted, p. 397; the locality “ Orizaba ”

must therefore be erased and transferred to I. basalis. The male, of which I have

since detected an example in Mr. FI’. Bates’s collection, has the basal joint of the

antenne flattened and curved, and nearly as long as 2 and 3 united, the latter

subequal, these organs being entirely black (in WM. albida the basal joints are usually

MACROBASIS.—GNATHOSPASTA. 403

rufo-testaceous) ; in the female the basal joint is shorter and less dilated, and the third

is a little longer than the second or fourth. ‘The anterior tibiz have two spurs in the

male. MM. basalis approaches M. segmentata in the structure of the antenne; it very

closely resembles the cinereous variety of Epicauta cinerea, but may be known at once

from that insect by the third joint of the antenne being much less elongate, not or

very little longer than the second.

GNATHOSPASTA.

Gnathospasta, Horn, Trans. Am. Ent. Soc. v. p. 154, fig. (mouth-parts) (1875).

This genus is closely allied to Epicauta and Macrobasis, but differs from both in the

very deeply emarginate labrum, and in the largely-developed, prominent, pincer-like,

unemarginate mandibles. A single species, G. mimetica, from Texas, is included in it

by Dr. Horn. Cantharis (Macrobasis) labialis, Dugés *, is a true Gnathospasta, and

apparently only differs from G. mimetica by its black (not cinereous) pubescence. The

anterior tibie of G. labialis have two spurs in both sexes—the inner one slender, acute,

and curved, the outer one very long and stout, concave, and truncate at the tip,—a

character not mentioned by Dr. Horn or Dugés. The basal joint of the antenne in the

male, as in various Macrobases, is flattened and elongated, and sinuate on the outer

side towards the tip.

Hab. Mexico, Pénjamo in Guanajuato (Dugés! 2).

Described from abraded examples, which were found mixed with a large quantity of

Cantharine collected at Pénjamo for medicinal purposes. The antenne of the male are

described and figured as having their first joint about three times as long as the second,

curved, and emarginate internally beyond the middle (so that the interior edge appears

to be angularly dilated), the second joint cylindrical, and the third one half the length

of the first.

The head is very large in both sexes. It is not unlikely that G. labialis will prove

to be inseparable from G. mimetica, Horn. Of G. labialis we have received two males

and one female; a single example only (¢ ) of G. mimetica served Dr. Horn for his

description.

Epicauta.

EPICAUTA.

p- 95 (1873); Leconte & Horn, Class. Col. N. Am. p. 421 (1888).

The highlands of Mexico and the adjacent regions to the northward are particularly

rich in species of this genus, and the headquarters of Zpicauta in the New World would

appear to be in Mexico, its members rapidly diminishing in number southwards.

Forty-nine species * (as against thirty-five from the United States) are here enumerated

from Mexico or Central America: of this number seven only extend to Guatemala or

Nicaragua, and one (E. carmelita) to Colombia. Panama appears to have but three

species, two of which are South American. The Mexican picautw have been

monographed by Dugés [An. Mus. Michoacano, ii. pp. 60-91 (1889)], and many

species have also been described by Haag, these authors having in numerous cases

described the same species under different names; thirty-two are enumerated by

Dugés. As in Macrobasis, the male-characters in the antenne, anterior tibiae, &c.

are of the utmost importance for discriminating between the numerous closely-allied

forms, more particularly as regards the species with cinereous or black pubescence,

the colour of the pubescence itself being sometimes variable (E. cinerea, &c.). The

punctuation of the head and thorax also varies greatly in some of the species (¢. g. in

E. curvicornis), and it cannot always be relied upon as a specific character. In one

interesting new species from Coahuila (£. singularis) the suture of the elytra is

longitudinally raised at about one-third from the apex in the female. The antenne,

the intermediate joints of which are sometimes distorted (E. curvicornis) or dilated

(E. basimacula, &c.) in the male, show every gradation in structure from strongly

setaceous to filiform; but in the following “Key” I have not thought it safe to group

the species upon this character (as is done by Dr. Horn), as some of them would be as

well placed in one section as the other. All the species here referred to Epicauta have

a silky-pubescent concave space on the inner face of the anterior femora and tibie

in both sexes. E. subatra, E. apicalis, and EF. subrubra, Dugés, and £. dohrni,

E. haroldi, and E. modesta (Haag) are unknown to me, and may be incorrectly placed

in the “Key.” These insects are chiefly found in the dry-season, upon flowers, some-

times in the greatest profusion.

Not uncommon in Mexico. ‘There are two well-marked forms of this remarkable

species: one (as described by Haag * and Dugés®) with the head and thorax sparsely,

coarsely, irregularly punctured, the pubescence of the upper surface sparse and black,

the sutural and lateral margins of the elytra cinereous; the other with the head and

thorax closely, finely punctate, and the pubescence denser and uniformly cinereous, or

(two examples from Amula) purplish-red. The sexual characters are precisely similar

in both forms. In the male the antennal joints 1-6 are shining and almost smooth,

7-11 densely punctured and opaque; 1, 3, 4, and 5 are exceedingly stout, 2 very short ;

6 is strongly and obliquely produced on the inner side, and 7 is articulated to it at the

middle of the outer side, instead of at the apex. In the female the antenne are

subfiliform, joints 4-6 being subequal and much shorter than 3 or 7, 7-11 elongate

and gradually increasing in length. The basal joint of the anterior tarsi is feebly

dilated, and the anterior tibiee are bicalcarate, in the male. The spurs of the hind

tibiz are long and subequal. All the numerous Oaxaca examples but one belong to

the dark form, those from Guerrero to the light one; intermediate forms occur at

Parada, Orizaba, and Oaxaca.

apices are luteous or fulvous, ‘The pubescence on the head, thorax, and scutellum is

cinereous- or brownish-cinereous, that on the elytra brown or blackish-brown; the basal

margin of the thorax and the sutural and lateral margins of the elytra are whitish-

pubescent. The outer spur of the hind tibie is broader and stouter than the inner

one. The male has the joints 3-6 of the antenne flattened and considerably dilated,

and a single spur to the anterior tibia. There can be little doubt that the insects

described by Haag! and Dugés? belong to one and the same species, notwithstanding

certain discrepancies in the description: Dugés omits to mention the basal spots of the

elytra, and Haag the fulvous apex. It is probable that they only had discoloured or

worn specimens before them. A male from Iguala is figured.

Geronimo (Champion); Nicaragua, Chontales (Janson).

This is the commonest species of the genus in Mexico, and we have received hundreds

of specimens of it. Two forms occur:—one with the apices of the elytra, and some-

times the humeri and sides also, luteous, and the suture, lateral margin, and a median

line on the disc clothed with lighter pubescence than the rest of the surface (E. rujfipedes,

Dug., = subvittata, Haag); the other with an elongate-triangular scutellum patch,

and the suture, apex, and lateral margin of the elytra, to a variable extent, luteous or

ferruginous, and the median line of lighter pubescence partially or entirely obsolete

(£. cinctella, Dug.). The Yucatan and Guatemalan specimens are intermediate, and

might equally well be placed with either. Both forms were found in plenty at Oaxaca.

In many undoubted examples of HL. rufipedes the median line of lighter pubescence is

more or less evanescent, or even obsolete, so that but little value can be placed on it as

a specific character. In the male of this species the third and following joints of the

antenne are flattened and strongly compressed—3 elongate-triangular, three times as

long as, and twice the width of, 2, 4-10 subequal in length, but diminishing in width,

4 and 5 as wide as, but much shorter than, 3; the anterior tibie with a single spur.

The legs are reddish-testaceous, with the tarsi infuscate or black. The antenne are

long and setaceous, black, the intermediate joints much narrower in the female than

in the male.

In two examples (2 )—one from Tapachula, the other from Chontales—the elytra

are fuscous, with the median vitta unusually well defined, the reverse being the case in

all those from Guatemala and Yucatan.

Specimens of Lytta subvittata, determined by Haag himself, are before me; they

differ in nothing from &. rufipedes, Dugés.

Hab. Nortn America, Texas ?,—Mexico, Guanajuato (Dugés 12, Sallé).

In the Sallé collection there are ten specimens labelled as belonging to this species.

If these are correctly named, EH. cupreola is extremely close to #. rufipedes, and only

differs from it in its darker body and legs, and in the elytra not having a median line

of lighter pubescence on the disc. The pubescence is cinereous, with the sutural,

apical, and lateral margins paler. The male has a single spur to the front tibie, and

the antenne formed as in EL. rufipedes; but the apical joint of the maxillary palpi

appears to be more dilated. Dr. Horn® states that E. cupreola is closely related to the

uniformly cinereous variety of H. cinerea: the dilated, strongly compressed intermediate

joints of the antenne, and the single spur to the anterior tibie, in the male,

sufficiently distinguish E. cupreola from E. cinerea in all its varieties. There are

discrepancies between Dugés’s descriptions 1, and the specific name is alogether mis-

leading.

EPICAUTA. 409

A common species in Mexico, extending southwards into Alta Vera Paz. £. rufi-

pennis was described by Chevrolat from an abraded example, and the specific name is

misleading, the elytra being testaceous or luteous, with yellowish pubescence. The

pubescence on the head is in great part ochreous, that on the thorax and under surface

cinereous. The last joint of the maxillary palpi is short and dilated, and the anterior

tibiz have a single spur, in the male.

In this species the head, thorax, scutellum, and under surface are deep black; the

elytra with a large apical patch, and usually the base very narrowly, black, and for the

rest luteous or fulvous, with dense yellowish-cinereous or fulvous pubescence. The

male has a single spur to the front tibie. The eyes are deeply emarginate. The

following species, E. apicalis, Dugés, appears to be a closely-allied form.

Not uncommon in the highlands of Mexico. The species is black, densely clothed

with rather coarse cinereous pubescence, the elytra each with a small black spot on

the middle of the disc towards the apex. The antenne are moderately long, sub-

filiform, very little thinner towards the tip, and rather stout in both sexes, the third

joint twice as long as the second. The male has the anterior tibie strongly sinuous

11 longer than 10, pointed; prothorax longer than broad, subparallel behind, somewhat obliquely

narrowed anteriorly, densely, moderately finely punctate, the punctuation becoming coarser towards

the apex, the disc feebly transversely depressed before the middle, depressed in the centre before the

base, and with a faint median line; elytra moderately elongate, widened a little posteriorly, densely,

very finely punctate; beneath densely punctured ; the spurs of the hind tibia stout; the anterior tibie

with a single spur in the male.

Length 13-18 millim. (¢ 92.)

Hab. Mexico, Cordova and Oaxaca (Hodge).

Found in numbers by Herr Hoge. Very close to &. nigra, with which I at first

confounded it; but differing from that species in the coarser punctuation of the head

and thorax, the latter more obliquely narrowed anteriorly, less depressed in the middle

behind, and more obsoletely canaliculate, the antenne stouter, the anterior tibie with a

single spur in the male. The only North-American species nearly allied to £. atripilis

are LE. funebris, Horn, and &. levettei, Casey, but both these have two spurs to the

anterior tibiz in the male. . corvina has a much less elongate thorax.

13. Epicauta cinereiventris. (Tab. XIX. fig. 8,4, var.)

Elongate, deep black, sparsely pubescent, the head and prothorax shining, the elytra opaque; the pubescence

of the upper surface, the scutellum (and: sometimes the basal margin of the prothorax) excepted, black,

that of the under surface and of the femora to a greater or less extent (the apex of the latter excepted)

cinereous or yellowish-cinereous. Head coarsely but not very densely punctate, with a smooth, narrow

rufous space in the middle between the eyes; antenne and palpi as in &. atripilis; prothorax as in

E. atripilis, but more coarsely and less densely punctured, the punctures becoming still coarser anteriorly,

those on the middle of the disc usually separated by irregular smooth spaces ; the elytra asin £, atripils ;

the anterior tibize with a single spur in the male.

Var. The apices of the elytra towards the suture rather broadly, and the basal margin of the prothorax, very

narrowly, cinereo-pubescent.

Hab. Mexico, Tehuantepec (Sal/é).

Nine examples of the type, one only (a male) of the variety. At first sight,

E. cinereiventris would appear to be only a variety of HL. atripilis with the pubescence

of the lower surface cinereous; the punctuation of the head and thorax, however,

is much coarser and not so dense, the latter having smooth, irregular, small spaces on

the disc, and the pubescence sparser. In the single (?) example from Acaguizotla

the under surface and the femora (except at the tip) are entirely cinereo-pubescent ; in

the other specimens the apical one or two segments are black, the sides of the meta-

sternum and of the abdomen also marked with black. . melanota (Makl.), from

Colombia, is an allied form, but differs in its very densely and finely punctured thorax

and slender antenne.

14. Epicauta evanescens.

Moderately elongate, black or blackish-brown, the head and prothorax shining, the elytra opaque; finely,

sparsely pubescent, the pubescence not hiding the sculpture, in great part cinereous, that on the elytra

variable—black or purplish, or with intermixed cinereous hairs, the base, suture, and apex rather broadly,

and in one specimen the sides also, indeterminately cinereous; the under surface very sparsely cinereo-

pubescent. Head rather coarsely, closely punctate, with an indistinct median groove and the usual fulvous

streak between the eyes, the latter large and somewhat prominent, the labrum rather deeply emarginate ;

last joint of the maxillary palpi (¢) elongate, obliquely truncate at the tip; antenne black (obscure

ferruginous in one specimen), subfiliform, becoming a little thinner towards the tip, moderately long, stout,

joints 1 and 3 about equal in length, 2 short, 4-10 subequal, much shorter than 3, 11 a little longer

than 10; prothorax campanulate, slightly dilated at the base, fully as long as broad, closely, rather coarsely

punctate, with a smooth, well-marked median groove; elytra moderately long, subparallel, finely scabrous-

punctate; legs stout, black or blackish-brown, the spurs of the hind tibie equal; anterior tibiee with a

single spur in the male.

Length 103-14 millim. (¢ 9.)

Hab. Guatemata, Champerico (Champion).

Two males and one female, from the vicinity of the Pacific coast. ‘This obscure

species is perhaps nearest allied to #. unicalcarata, from which it differs in the coarsely-

punctured head. The filiform, shorter antenne, the more campanulate thorax, the

latter with sharply-defined median groove, and the less elougate shape distinguish

E. evanescens from E. cinereiventris, which has a variety with the apex of the elytra

cinereous. It is probable that the elytral pubescence may vary in colour to entirely

Epicauta vicina, Dugés, An. Mus. Michoacano, ii. p. 70°.

Hab. Mexico, Guanajuato (Dugés1, Sallé), Michoacan (Dugés *).

We have received one female and two male examples of this species. H. horni

chiefly differs from its allies by the fine punctuation of the head and thorax. The

antenne are moderately long and filiform, not thinner towards the tip. The anterior

tibie have a single spur in the male. The pubescence above and beneath is uniformly

cinereous and rather dense. Dr. Horn (Trans. Am. Ent. Soc. xii. p. 107) remarks that

“ E. vicina belongs to the series with filiform antenne, and is most closely related to

E. sericans, Lec.” ; the antenne, however, are much more elongate, the joints less

closely articulated. JLytta vicina, Haag (1880), from Brazil, is an Hpicauta, and

Dugés’s second name, vicina, as well as his first, cinerea, is preoccupied.

16. Epicauta unicalcarata.

Elongate, narrow, subparallel, black, opaque, above and beneath sparsely uniformly clothed with fine cinereous

pubescence. Head finely, sparsely, shallowly punctate, with a faint median line and a longitudinal

fulvous streak in the middle between the eyes, the latter large and deeply emarginate, the labrum feebly

so; maxillary palpi stout, black, the apical joint oblong-ovate, obliquely truncate at the tip; antenne

black, stout, filiform, the joints flattened-cylindrical and not tapering outwardly—1 and 3 about equal

in length, 2 short, not half the length of 3, 4-10 subequal, much shorter than 3, 11 longer than 10; pro-

thorax rather longer than broad, narrower than the head, campanulate, slightly dilated at the base, densely,

rather coarsely punctate (the punctures here and there confluent and very much coarser than those on the

head), and finely canaliculate; elytra elongate, broader than the prothorax, shallowly and thickly punc-

tured ; legs stout, comparatively short, the tarsi especially, the spurs of the hind tibiz subequal ; anterior

tibiee with a single spur in the male.

Length 10 millim. (¢.)

Hab. Mexico, Amula in Guerrero 6000 feet (H. H. Smith).

Though we have received but a single ( ¢ ) example of this species, it is advisable to

name it. In having a single spur to the male anterior tibia and filiform antenne,

E. unicalcarata approaches E. horni (vicina, Dugés), from which its longer, more

coarsely punctured, thorax, larger eyes, and stouter antenne distinguish it at a glance.

The pubescence is sparse, and does not hide the punctuation; the punctures on the

head are fine and sparse, those on the thorax much coarser and more closely placed ;

the legs and antenne are stout and comparatively short.

The dissimilar punctuation of the head and thorax (resembling that of the

N.-American £. trichrus, Pall.), apart from other characters, will separate EF. unical-

carata from LE. stigmata, FH. cinerea, &c.

feet (Champion).

Apparently a common species in Mexico, whence we have received a large number

of specimens from various widely-separated localities, and extending southwards to the

Los Altos region of Guatemala. It varies in the number and size of the denuded spots

on the upper surface. In the typical E. maculata (Say) (as in E. ocellata, Dugés) the

elytral spots are numerous and comparatively large; in the var. conspersa, Lec.

(= punctuata, Dugés), they are smaller and more scattered; and in the var. media, Dugés,

414 HETEROMERA.

they are very small and few in number. Of upwards of fifty specimens before me

thirteen belong to E. maculata, two (including the single example from Guatemala) to

. media, and the remainder to E. conspersa. . conspersa (punctuata, Dugés) appears

to have longer antenne (in both sexes) than E. maculata, as stated by Leconte‘.

Allied forms, £. nigropunctata (Blanch.), E. atomaria (Germ.), &c., occur in South

America.

Hab. Mexico, Hacienda de la Noria in Michoacan (Dugés!), Michoacan (Flohr 2),

This species is exceedingly close to the typical form of EF. maculata, which also

occurs in Mexico, and only separable therefrom by the elongate apical joint of the

maxillary palpi in the male sex: this joint is more than twice as long as broad in the

single male example before me (in E. maculata, 3, it is shorter and wider, nearly as

broad as long). Dr. Horn (Trans. Am. Ent. Soc. xii. p. 107) states that E. ocellata is

a variety of L. maculata.

Not uncommon on the Atlantic slope, extending from the Mexican State of Vera

Cruz to Nicaragua. It was found in plenty by Mr. Smith at Teapa in Tabasco.

Closely allied to E. lemniscata, but broader; the ground-colour of the head and thorax

entirely or in great part black, the underside and the legs, the trochanters and the

basal two-thirds of the femora excepted, also black. In most of the southern specimens

EPICAUTA. A415

and in one from Frontera, Mexico, the two external black vitte of the elytra

are confluent, or, at most, separated by a fine line of light pubescence. The

thorax is elongate, transversely depressed before the apex, and parallel at the sides

behind. The anterior tibiz have two spurs in the male. The labrum is rather

deeply emarginate.

Dugés* describes an Hpicauta from the Sierra de San Luis Potosi, Mexico, under

the name of £. vittata (Fabr.); but, from the description, I have no doubt that his

insect is really referable to the closely-allied EH. lemniscata. Both Leconte? and

Horn? state that E. lemniscata replaces E. vittata in the Southern States. I have not

seen a specimen of either from within our limits. According to Dr. Horn?, E. vittata

is abundant in early summer on potato and tomato-plants in the Middle States.

Not uncommon in Chiriqui. Allied to £. vittata, but smaller and narrower; the

thorax black ; the elytra with the shoulder, the lateral margin, a slender median vitta

nearly or quite reaching the apex, and sometimes a narrower abbreviated vitta within

the margin, luteous, the suture, at most, very narrowly luteous; the underside and

legs black, the coxe and the extreme base of the femora reddish-testaceous. The

thorax is long and narrow, parallel at the sides behind. The eyes are very large and

deeply emarginate; the spurs of the hind tibie are slender and subequal; and the

anterior tibiz are bicalcarate in the male. In E£. vittata and E. lemniscata the suture

is rather broadly luteous, the black stripe on either side of it does not extend so near

to the base, and the humeri (as in £. vitticollis) are not entirely luteous. |

23. Epicauta unilineata. (Tab. XIX. fig. 13.)

Elongate, opaque, very finely and closely punctured, finely pubescent; the head reddish-testaceous, with two

spots of variable size on the vertex, the mouth-parts, and eyes black, the pubescence yellowish; the

thorax black, with a median vitta and the sides yellowish-pubescent ; the scutellum luteous ; the elytra

black, with the lateral margin, the apex, and a narrow median vitta—widening a little in front and

curving round towards the scutellum, but not extending to the humerus—flavo-luteous, the pubescence

partaking of the ground-colour ; beneath black, cinereo-pubescent ; legs black, the coxe, the basal third

or more of the femora, and the claws reddish-testaceous. Head broad, with a well-marked median groove,

the eyes moderately large and deeply emarginate, the labrum also deeply emarginate ; antenne setaceous,

rather slender, black, the two basal joints sometimes paler, joint 3 a little longer than 1 ; prothorax

longer than broad, very much narrower than the head, transversely depressed anteriorly, and with a

median groove, the sides converging in front, subparallel behind ; elytra wider than the head, moderately

elongate; posterior tibial spurs subequal, slender ; anterior tibia with two spurs in the male.

Length 9-12 millim. (¢ @.)

Hab. GuaTEMALA, near the city 5000 feet (Salvin), San Gerdnimo (Champion).

Closely allied to E. grammica, but with the discoidal luteous vitta of the elytra not

extending to the shoulder and the apex rather broadly margined with yellow: in

E. grammica the lateral and discoidal luteous stripes are rather broadly confluent at

the base. Numerous examples.

Hab. Mexico !? (Saillé, ex coll. Sturm), Acapulco (Hoge, H. H. Smith), Acaguizotla,

Tierra Colorada, and Hacienda de la Imagen, all in Guerrero (H. H. Smith), Jalapa

(Hoge).

This fine species appears to have been unknown to Dugés. ‘The pubescence of the

head and thorax is variable in colour: in one example, from Jalapa, the thorax is

cinereo-pubescent, with a black stripe on either side of the disc, and the head is in

part cinereous, this example nearly agreeing with the description’; in the eight others

before me the head and thorax are black-pubescent. The light pubescence is very

coarse, and may be white, cinereous, or golden; in some specimens the median vitta

of the elytra is dilated posteriorly and nearly joins the sutural stripe. ‘The ventral

segments 1-3 or (rarely) 1-4 have each a broad belt of light pubescence at the apex.

The anterior tibie have two spurs in the male. The antenne are long and subfiliform,

tapering towards the apex, the third joint very elongate. Haag has described (op. cit.)

two different species under the name Lytta niveolineata—one from Mexico, the other

from the Himalaya; the latter has been renamed atkinsoni by Beauregard.

appears to have been known to Dugés. In the male joints 3-6 of the antenne are

flattened and almost smooth, 3 being very stout and about twice as long as 5; the

anterior tibiz are strongly compressed before the middle, widened towards the apex,

their lower surface concave, smooth, and glabrous, and furnished with a dense brush

of hairs.at the base, the apex bicalcarate ; the lower surface of the anterior femora is

hollowed out towards the apex and glabrous; and the basal joint of the anterior tarsi is

somewhat abruptly widened from the middle, and glabrous at the base beneath. In

some specimens the inner discoidal stripe of the elytra is obsolete; the short, fine,

submarginal line is rarely visible. The outer spur of the hind tibie is broad and

compressed, rounded at the tip, the inner one slender and acute. E. duplicata, Casey,

is, no doubt, based upon a small female example of this species.

We have received seven specimens of this species—six from Canelas and one from

Ventanas. E. jimenezi is perhaps nearest allied to E. pennsylvanica, but is very much

larger than that insect (equalling E. corvina in this respect), and also differs from it in

the purplish elytra and in having the spurs of the hind tibiz subequal ; the male, as

in E. pennsylvanica, has two spurs to the anterior tibiz. The antenne are filiform,

becoming a little thinner outwardly, the third joint very elongate ; the labrum is rather

deeply emarginate.

Found in plenty by Herr Hoge at Villa Lerdo. As Dugés remarks, this species

may be known from &. corvina (=nigerrima, Dug.) by its smaller size and by the outer

spur of the posterior tibiz being spoon-shaped and much broader than the inner one.

Durango specimens agree perfectly with others from Texas before me. This insect is

We have only received three specimens that can be satisfactorily referred to

. nigra. Dugés also quotes? Jalapa (Flohr) as a locality, but it is probable that the

Jalapa insect belongs to another species. E. nigra is one of several very closely-allied

forms, which are difficult to separate except by male characters; and, as Dugeés

remarks ?, small examples of it resemble the black variety of E. stigmata. The speci-

mens I refer to the present species have the pubescence entirely black; the antenne

long and setaceous*, the first joint elongate, longer than the third, the latter also

elongate; the thorax longer than broad, more elongate than in E. stigmata, sub-

parallel at the sides behind, densely and finely punctate, and with well-marked median

depression ; the anterior tibie with two spurs in the male; the spurs of the posterior

tibize subequal, stout. Dr. Horn informs me that £. funedris differs from E. nagra,

Dugés, in its stouter hind tibial spurs, and in not having a median thoracic impression ;

nevertheless, it is probable they are not really distinct.

31. Epicauta atricolor.

Elongate, black or blackish-brown, above and beneath somewhat thickly clothed with similarly-coloured

decumbent pubescence. Head densely, finely punctate, ohsoletely canaliculate, with a smooth reddish,

narrow, longitudinal space in the middle between the eyes, the latter large and deeply emarginate ; last

joint of the maxillary palpi ( d ) elongate-ovate, obliquely truncate at the tip; antenne stout and filiform

in both sexes, becoming slightly thinner towards the apex, moderately long in the male, a little shorter in

the female, joint 1 comparatively short, stout, 2 very short, 3 twice as long as 2 and one-half longer than

4, 4-10 subequal ; prothorax about as long as broad, subcampanulate, densely, finely punctate, and with

a smooth, impressed median line, the disc depressed in the middle before the base ; elytra densely, finely

punctate; spurs of the hind tibie rather stout, subequal ; the anterior tibia with two spurs in the male.

Length 10-14 millim. (¢ 9.)

Hab. Mexico, Matamoros Izucar, Oaxaca (coll. F. Bates, Sallé), Jalapa (Hedge).

Eight examples. Specimens of this perplexing species are labelled with the pre-

occupied name of Cantharis fumosa, St., in the Sallé collection; others are ticketed

E. nigra, Dugés, teste Haag, in that of Mr. F. Bates. 4. atricolor approaches the

N.-American E. puncticollis and E. oblita in the form of the antenne, but differs from

both of them in the densely-punctured head and thorax, decumbent pubescence, and

longer antenne. The much shorter, stouter, and more filiform antenne separates it

from E. nigra (as here understood) and £. atripilis; in its bicalcarate anterior tibie in

the male it agrees with HL. nigra. E. pennsylvanica has a more quadrate thorax,

unequal hind tibial spurs, more setaceous antenne, &c. In one abraded (? abnormal)

example from Matamoros Izucar the head and thorax are more coarsely and sparsely

punctate; it may belong to another species.

We have received an abraded example (3) of an Epicauta possibly belonging to

this species. E. leoni (3) is described as having the first joint of the antenne

sinuous on the inner side towards the apex, appearing subangular in the middle, joint

2 half the length of 3, 3 longer than 4, 4-10 subequal. The specimen (¢) from

Tenango del Valle is black, with sparse, fine, black pubescence, and, at first sight,

Not uncommon in the highlands of Mexico. . cinctipennis may easily be known

from E. cinerea (margined form) by its short, subtransverse, less densely-punctured

thorax, more filiform antenne, and more slender hind tibial spurs. The antenne, as

in E. cinerea, have the third joint unusually elongate, longer than the first, the latter

short. The anterior tibiz have two spurs in the male.

Found in plenty by Herr Hége at Tupataro. This species, as Dr. Horn remarks

(Trans. Am. Ent. Soc. xii. p. 107), is related to E. cinerea, but is more slender; the

thorax is much more elongate and more rugosely punctured, and the first joint of the

~ antenne is longer (not shorter) than the third, the latter relatively less elongate. The

elytra are stated by Dugés? to have the sutural, apical, and lateral margins fringed

with yellow pubescence; in all the examples before me the pubescence along the

apical margin is black. The apical margin of each ventral segment Is yellowish-

pubescent. The anterior tibie have two spurs in the male. Dugés’s figure (5) is

incorrect and misleading, the elytra being re presented much too short.

of the upper surface cinereous ; beneath cinereo-pubescent, the metasternal side-pieces and the sides and

tip of the venter sometimes marked with black; legs black-pubescent, the base of the femora only with

cinereous hairs. Head densely, finely punctate, more sparsely so in front, with a smooth median line,

which is of a fulvous colour between the eyes, the latter deeply emarginate and not prominent, the labrum

and stout, the spurs of the hind tibie long, stout, and subequal; last ventral segment rather deeply

emarginate, and the anterior tibie with two spurs, in the male,

Length 18-19 millim. (¢ 2.)

One female and two males. Allied to Z. cinerea, but differing from that species in

all its varieties by the more elongate basal joint of the antenne (this joint is shorter

than the third in E. cinerea) and the longer thorax, as well as in the arrangement of

the pubescence on the elytra. The punctuation of the head and thorax is dense and

fine, finer than in E. funesta, E. atripilis, E. atra, &c. The antenne in the female are

a little shorter than in the male. The pubescence on the terminal dorsal segment is

black.

This appears to be an extremely variable insect as regards the colour of the pubes-

cence, the two forms apparently belonging to one and the same species. We have

received about an equal number of each from within our limits, mostly from the

Atlantic slope; the cinereous variety does not extend south of Mexico. The two forms

have not been received from any one locality in Central America, and they may prove

to be distinct. Central-American specimens of the typical form agree with others

before me from the United States. The insect also varies enormously in size, from

10-24 millim. The cinereous variety of it may chiefly be known from the similarly-

coloured allied forms by the slender, moderately long, and gradually tapering antenne,

the third joint of which is unusually elongate; the apical three joints in the female are

much shorter than the intermediate ones; the basal joint is comparatively short. ‘Lhe

anterior tibie have two spurs in the male.

E. cinerea by its filiform (not setaceous) antenne, joints 3-6 of which (3 especially)

are much less elongate ; and by its narrower and less robust shape. . stigmata is, in

fact, exceedingly closely allied to E. horni (vicina, Dugés); but differs from it by the

more finely punctured head and thorax, the latter more campanulate in shape, and by

the anterior tibiz having two spurs inthe male. The pubescence varies in colour from

cinereous to black, with intermixed cinereous hairs.

Found in plenty by Herr Hoge at Oaxaca and Mexico city. Variable in the colour

of the pubescence, from black with intermixed cinereous hairs (as described by both

Haag and Dugés) to entirely cinereous or fulvo-cinereous. The thorax is subquadrate,

rounded at the sides anteriorly, shorter in the female than in the male, deeply canali-

culate, and somewhat densely, finely punctate. In about half the specimens before me

(including a typical EL. neglecta determined by Haag himself) there is a smooth bare

spot on either side of the disc about the middle (as in £. callosa, Lec.), a character

not mentioned by either Haag or Dugés; this is most distinct in the specimens with

light pubescence, in many of the dark examples there is no trace of it. The antenne

are long and subfiliform, becoming slightly thinner towards the tip, the third joint

elongate. The anterior tibize have two spurs in the male; those of the hind pair are

subequal. In one male example from Mexico city (fig. 21) the head is enormously

enlarged. The typical specimen (3) of HE. neglecta (Haag), in Mr. F. Bates’s collec-

tion, is more elongate than usual, but with the long series before me I am unable to

separate it as distinct. The much longer antenne and subequal hind tibial spurs

separate L. neglecta from E. candidata, the last-mentioned character also distinguishing

the dark varieties of it from EH. pennsylvanica. In most of the specimens with

light pubescence the smooth spots on the thorax are as distinct as they are in

E. callosa.

Not uncommon in the State of Vera Cruz, whence we have received upwards of fifty

examples. . obesa may be known from the allied uniformly cinereo-pubescent species

by the strongly setaceous antenne in the male sex, joints 3-6 moderately thickened,

and 4 and 5 together not much longer than 3, 1 comparatively short; in the female

joints 3-6 are more slender, 4—6 more elongate. The pubescence is fine and not very

dense. The anterior tibie have two spurs in the male; the outer spur of the hind

pair is stouter than the inner one. The head and thorax are closely, finely punctate,

the epistoma and labrum more coarsely and sparsely so.

Lytta mus, Haag, to judge from a specimen ( 2 ) from Orizaba (determined by Haag

himself) before me, is inseparable from E. obesa.

42. Epicauta auricomans, (Tab. XIX. figg. 22,¢; 22a, antenna, ¢ .)

Moderately elongate, black, above and beneath densely, uniformly clothed with rather coarse golden or

cinereous pubescence ; the legs yellowish- or cinereo-pubescent, with the tips of the femora and tibie and

the tarsi entirely piceous or black. Head closely, finely punctate, coarsely so in front, and with a fine

median groove, the labrum feebly emarginate; antenne black or piceous, setaceous, moderately long,

joints 3-6 stouter in the male than in the female, 3 very elongate, much longer than 1, the latter com-

paratively short ; prothorax subquadrate, with the sides rounded and converging in front, punctured like

the head, and with a fine median channel ; elytra wider than the prothorax in both sexes, very finely

scabrous-punctate ; legs piceous or black, long and stout; the spurs of the hind tibie rather stout, sub-

obtained with others of the same sex at the same locality, the hind tibie are strongly

and abruptly bowed inwards at about one third from the base.

43. Epicauta leucocoma, (Tab. XIX. fig. 23, 3.)

Elongate, narrow, subparallel, black, somewhat thickly clothed with fine, whitish-cinereous pubescence, the

under surface with whiter hairs. Head minutely and closely punctured, somewhat flattened between the

eyes, and with a smooth median line, the labrum feebly emarginate, the eyes large; maxillary palpi

reddish-testaceous, the apical joint infuscate, the latter elongate and rather narrow in the male ; antenne

black or piceous, with joints 1-3 or 1-4 reddish-testaceous towards the base, long, slender, and filiform,

426 HETEROMERA.

We have received five specimens of this species from Northern Mexico. Haag®

states that his LZ. sartori?, which he described (imperfectly) from a single example, is

possibly a variety of E. ferruginea, and in this I am inclined to agree with him; I have

not, however, seen a specimen from so far south. The Mexican:examples have

cinereous pubescence and they agree well with the similarly-coloured Texan specimens

before me.

E. ferruginea and the following two species belong to a little group in which the

antenne are very short, similar in thickness throughout, and with the joints closely

articulated; no species of this section appears to have been known to Dugés. An

abundant species in the Southern States.

46. Epicauta candidata.

Moderately elongate, black, above and beneath densely clothed with coarse, decumbent, whitish-cinereous

pubescence; the head and prothorax closely and finely punctured, and each with an impressed median

line, the prothorax with an ill-defined, small, smooth spot on either side of the disc about the middle,

the elytra more finely punctate. Head very little wider than the prothorax, the epistoma and labrum

with a few coarse scattered punctures, the labrum feebly emarginate, the eyes narrow and feebly emargi-

nate; antennee black, short, about reaching the base of the prothorax, the joints closely articulated,

cylindrical, 1 and 3 about equal in length, 3 twice as long as 2, and one-half longer than 4, 4-10 sub-

equal; prothorax as long as broad, subcampanulate, slightly sinuous at the sides behind; elytra con-

siderably wider than and about four times as long as the prothorax, widening to beyond the middle ;

beneath closely and finely punctured ; the spurs of the hind tibiz stout, unequal, the outer one broad and

spoon-shaped.

Length 144 millim. ( 9.)

Hab. Mexico, Villa Lerdo in Durango (Hége).

In having a smooth, bare, small spot on either side of the disc of the thorax, and

‘also in its short antenne, this species resembles the North-American £. callosa, Lec.

(numerous specimens of which from Texas are now before me), from which it differs in

its much larger size and more elongate shape, the narrower and more transverse eyes,

the unequal spurs to the hind tibiz, and the less dense punctuation of the head and

thorax. The hind tibial spurs resemble those of HE. pennsylvanica. The pubescence

is very coarse, dense, and uniform.

47, Epicauta emarginata, (Tab. XIX. fig. 24.)

Moderately elongate, subparallel, black, very densely clothed above and beneath with coarse whitish pubes-

cence, the pubescence completely hiding the sculpture. Head densely, finely punctate, with a distinct

median line; the eyes rather prominent, scarcely emarginate ; labrum broadly, deeply, semicircularly

emarginate (having the appearance of being obtusely produced on either side in front); mandibles toothed

on the inner side towards the base, entire at the tip; last joint of the maxillary palpi oblong-ovate,

obliquely truncate at the tip; antennz black, short, about reaching the base of the prothorax when the

head is extended, the joints cylindrical, closely articulated, and not tapering outwardly—1 stout, about

as long as 3, 2 very short, 3 nearly twice as long as 4, 4-10 subequal, 14 one-half longer than 10; pro-

thorax a little broader than long, narrower than the head, transversely convex, the sides strongly rounded

before the middle and slightly converging behind, the hind angles very obtuse, the surface densely, finely

punctate, with a faint median line; elytra subparallel, moderately elongate, densely and finely granulate ;

beneath densely, finely punctate; legs short and stout, the hind tibial spurs slender, subequal; anterior

femora slightly dilated and with their inner face concave, and the anterior tibie with two spurs, in the

male.

Length 83-10 millim. (¢ 9.)

Hab, Mexico, San Isidro in Coahuila (Zége).

Five examples of this species were obtained by Herr Hoge during his second Mexican

expedition. In the form of the labrum F. emarginata is intermediate between

Gnathospasta and the normal Epicaute ; the mandibles, however, are shorter and less

developed than in Gnathospasta, and they are toothed on the inner side towards the

base. The present species resembles the cinereous variety of E. ferruginea, and has

the antenne formed as in that insect, but the thorax is more rounded at the sides, with

less prominent hind angles; the upper and under surfaces are densely, finely punctate,

and thickly clothed with coarse, whitish pubescence. . fisstladris, Lec., from Lake

Superior, &c., appears to have a similarly emarginate labrum.

maxillary palpi piceous or black, the apical joint oblong-ovate, rounded at the tip; antenne black, elon-

gate, filiform, rather stout, the joints flattened-cylindrical—1 comparatively short, not so long as 4, 2 very

longer than 10; prothorax transversely-subquadrate, the sides parallel in front and slightly sinuous

behind, the anterior angles prominent, the surface uneven, densely and finely punctate, the disc trans-

versely raised in the centre anteriorly, depressed between this and the apex, and with an interrupted

median groove, which is more distinct in front than at the base; elytra somewhat flattened on the disc,

minutely punctured ; beneath with an almost bare spot on the middle of each of the ventral segments,

these latter densely, finely punctate; legs black, densely cinereo-pubescent, the spurs of the hind tibie

slender; the anterior tibiee with two spurs.

The species hitherto referred to this genus are all American, and range from the

United States to Brazil. Pyrota differs from Cantharis and Pomphopea in the antenne

being setaceous or subfiliform, not thickened externally, and from Kpicauta, &c., by the

anterior femora and tibie being without a silky-pubescent concave space on their inner

face; all our species have the upper surface more or less yellowish, with black vitte or

spots, the black sometimes preponderating, and the elytra usually glabrous. The last

joint of the maxillary palpi in the male varies greatly in shape according to the species,

from exceedingly broad and somewhat scaphiform to obliquely pyriform, with the under-

side deeply excavated ; in P. rugulipennis, &c., it is elongate-ovate in both sexes, and not

excavate beneath in the male *. ‘The antenne have their first joint obliquely truncate,

and the second joint articulated to it near the outer apical angle, so that they appear to

be subgeniculate. In P. rugulipennis, 3, the sixth ventral segment (not the terminal,

or seventh, which is incised) has an elongate-triangular depression extending trom the

apex forwards, the depression filled with membrane, the same segment in the female

being deeply arcuate-emarginate at the apex.

only extending south of Mexico.

This species closely resembles the true P. myladrina, but differs constantly in the

elytral markings: the spot at the apex is in the form of a narrow transverse] y-lunate

fascia, which does not reach the apical, sutural, or lateral margins, this spot being very

rarely obsolete ; the post-median fascia is formed by two oblong, more or less coalescent,

spots, the inner one extending forwards; the two basal spots are oblong, the outer one

narrow and extending downwards. P. punctata also differs from P. mylabrina in its

much larger eyes, and in the sparser and more distinct punctuation of the elytra.

P. terminata has three broad black fasciz (the anterior two not reaching the suture),

and the elytra are more distinctly punctured. The apical joint of the maxillary palpi

in the male is moderately stout, obliquely-pyriform, Found in plenty by Herr Hoge

We have received nine examples of this species—six from Coahuila and three from

Tuspan; and others are contained in Mr. F. Bates’s collection.

P. mylabrina, Chevr., to judge from the specimens before me, varies but little in

elytral markings; it may always be known from the allied forms, P. terminata, Lec.,

and P. punctata, Casey, by its much smaller, more transverse eyes. The apical joint

of the maxillary palpi in the male is very stout, obliquely-pyriform. The elytra have

two spots at the base (the inner one rounded, the outer one narrow and oblong), a

transverse moderately large spot or fascia at the middle (not reaching the sutural or

lateral margins), and the apex rather broadly black, the apical fascia excised in the

middle in front. The allied P. engelmanni, Lec., from Texas, &c., has a broader

median and a narrower apical fascia, and the underside and legs black.

Head and prothorax shining, reddish-yellow, the former on all sides (so as to enclose a large oval frontal patch),

and the latter with an oblique patch on either side of the disc behind (the two more or less coalescent)

and a lateral spot, black—in one specimen both are entirely reddish-yellow; the elytra opaque, yellow,

with a large rounded spot close to the base (not reaching the suture or lateral margin) and a very broad

post-median fascia (not extending on to the lateral margin), black; beneath black, the terminal ventral

segments sometimes reddish-yellow ; legs reddish-yellow, the femora and tibie at their apex and the

tarsi black; antenne black, the basal one or two joints more or less reddish-yellow; the head and

prothorax finely and sparsely, the under surface coarsely and thickly, pubescent. Head sparsely,

coarsely punctate, the vertex sulcate, the eyes moderately large; apical joint of the maxillary palpi

~ narrow in both sexes, elongate-ovate, with the tip truncate, the underside not excavated in the male;

antenne strongly setaceous, moderately stout, joint 1 as long as 2 and 3 united, 3 considerably longer

than 4, 4-10 subequal in length, 7-11 rapidly diminishing in thickness, 11 very slender; prothorax

slightly longer than broad, narrowing in front, sparsely, irregularly, and rather coarsely punctate,

the disc transversely flattened before the middle, depressed in the centre at the base, and with a

smooth median space ; elytra densely scabrous-punctate, and with four very fine raised lines; beneath

thickly punctured; legs stout, the hind tibial spurs slender, subequal; sixth ventral segment (3) with

an elongate-triangular depression in the middle, extending from the apex nearly to the base, the

depression filled with membrane—( ? ) deeply arcuate-emarginate at the apex.

Length 134-20 millim. (¢ 2.)

Hab. Mexico, Canelas in Durango (Becker).

Five males and one female. This species, the sexes of which are difficult to distin-

guish, except by the form of the sixth ventral segment, may easily be known from all

the other Mexican Pyrote by its finely rugulose, opaque elytra, the latter with a large

rounded basal spot and a very broad, common, post-median fascia. The head and

thorax vary in colour, the black markings being entirely obliterated in one example ;

the apices of the elytra are yellow, the post-median fascia occupying from one-third to

nearly one-half of their total length.

extending forwards ; and two ( ¢) have this spot extending forwards so as to nearly or

quite join the humeral spot (as figured by Lacordaire®). The femora and tibiew are

usually yellow, with the tips black, but in one example they are entirely black; the

antenne and underside also vary in colour to entirely black; the apices of the elytra

are always broadly yellow. In the male the basal joint of the antenne is much

elongated, almost entirely yellow, and the apical joint of the maxillary palpi is very

large, obliquely pyriform, and considerably extended on the external as well as on the

inner side. P. maculata (Lacord.) is incorrectly identified by Burmeister (Stett. ent.

Zeit. 1881, p. 22) with P. vittigera, Blanch. ; and by Berg (An. Soc. Arg. xv. pp. 67,

(Dugés*), Plan del Rio (Hége), State of Vera Cruz (Sallé?, Dugés *), San Andres Tuxtla

(Sallé), Teapa in Tabasco (7. H. Smith).

Found in abundance by Herr Hoge at Plan del Rio. In this species the elytra have

a very broad black discoidal stripe, extending almost from the base to very near the

apex, often narrowed anteriorly and with a black spot between it and the suture; the

thorax with a large oblique patch on either side of the middle behind, and an oblong

patch on either side in front also black ; the antenne, the underside in great part, and

the legs (the coxee and the base of the femora excepted) black. The head is sulcate

between the eyes; the thorax has some coarse scattered punctures near the base; the

elytra (except at the base) are dull, densely, finely punctate, vaguely sulcate, with four

faint carine on the disc, and the sutural and lateral margins raised. In the male the

last joint of the maxillary palpi is exceedingly large, broadly transverse, and somewhat

scaphiform, the three basal joints of the anterior tarsi are very strongly, subangularly

produced on their inner side at the apex, and the sixth ventral segment is entire.

There can be little doubt that Lytta vittigera, Lec. (females only of which are known,

and whether they were obtained in Texas or Mexico is uncertain), is a variety of

P, tenuicostatis, Dugés, with the black vitta on the elytra narrowed anteriorly and

having a spot between it and the suture at the base; Dr. Horn’s description? applies

well to this form, which occurs also at Plan del Rio and Tuxtla.

We have received about forty specimens of this species, of which six belong to the

var. clavipalpis. Varies greatly in the extent of the black markings on the thorax

and elytra, and in the colour of the underside and legs, also in size, from 83-25 millim.

P. clavipalpis only differs in colour, and an example of it was obtained at Yautepec

with one of the palest forms of P. divirgata.

In the palest specimens the elytral vitta is very narrow, in some specimens abbre-

viated anteriorly, and the basal spot is obsolete or nearly so. ‘The femora and tibie

may be yellow, with the tips only black. ‘The variety clavipalpis has the black greatly

extended on the elytra, a short median vitta and some additional spots on the thorax, and

the underside and legs almost black. The elytra are thickly, minutely punctate, and.

have some widely-scattered, shallow, coarser impressions. The antenne always have

their basal two or three joints pale. The last joint of the maxillary palpi is very

stout and obliquely pyriform in the male. The much longer, smoother, differently-

marked thorax, non-sulcate elytra, and different male-characters separate P. divirgata

in all its varieties from P. tenwicostatis.

434 HETEROMERA.

This is the only species of Pyrota known as yet as inhabiting the southern part of

our region, it ranging from the Mexican State of Vera Cruz to Panama. P. decorata

may be recognized in all its varieties by the dark suture of the elytra, in this respect

approaching the North-American P. germari (Hald.), with the description of which it

nearly agrees. The head and thorax vary in colour from black to rufous, two small

black spots on the disc of the latter excepted. In dark specimens the sutural stripe

of the elytra is dilated anteriorly into a large triangular patch—in pale ones it is

extended narrowly to the base, with a small oblong spot on either side of it; the

discoidal vitta varies from about half to two-thirds of the elytral width, and extends

from the humerus (where it is narrow) to near the apex. The legs, antennae, and

underside are black. The elytra are dull, densely, finely punctate; the thorax is

narrow and very elongate, with some fine, widely-scattered punctures and indistinct

transverse ruge; the head is sparsely, somewhat coarsely punctate, the vertex sulcate.

In some specimens the third joint of the antenne is shorter than the fourth. The

apical joint of the maxillary palpi in the male is very stout, obliquely pyziform.

Varies in length from 10 to 27 millim. The female only appears to have been known

to Haag. P. germari has a black head, with yellow frontal space, a reddish-yellow

thorax, with two black spots, and the basal half of the femora and tibie yellow.

Head and prothorax shining, reddish-testaceous, the prothorax with two spots on the disc and two on the

flanks, the eyes, and labrum black, the elytra dull reddish-brown, the antennew, legs (the rufous base of

the femora excepted), and underside black ; the head sparsely, the prothorax thickly, clothed with erect

yellowish-cinereous hairs, the elytra also with a few very widely-scattered, shorter, erect hairs; the

metasternum thickly, the rest of the under surface very sparsely, clothed with long hairs. Head sparsely

and somewhat coarsely punctate, sulcate on the vertex, the eyes large, feebly emarginate ; apical joint of

the maxillary palpi (¢ ) exceedingly broad and scaphiform, concave beneath, that of the labial pair (¢)

also very stout; antenne rather slender, setaceous, joints 3-10 subequal in length, but diminishing in

thickness ; prothorax'narrower than the head, longer than broad, narrowing in front, depressed in the

centre behind and broadly transversely flattened before the middle, thickly and somewhat coarsely

punctate, with a smooth, flattened, longitudinal median space; elytra about twice as wide as the

prothorax, elongate, vaguely, broadly, and rather deeply sulcate, sharply margined at the sides and along

the suture, and with four fine distinct raised lines, the surface (except at the base) closely and minutely

punctured ; beneath very shining, with widely-scattered minute punctures, the metasternum more

closely punctate; legs rather slender, the hind tibial spurs subequal; the three basal joints of the

anterior tarsi produced on their inner side at the apex, and the sixth ventral segment entire, in the male.

Length 15-21 millim. (¢ Q.)

Hab. Mexico, Acapulco (Hége).

One female and two males of this very distinct species were obtained by Herr Hoge.

The somewhat thickly punctured, hairy thorax, and the sulcate unicolorous elytra

distinguish P. hirticollis at a glance from all the allied forms. The elytral pubescence

is easily abraded, and it is probable that the elytra themselves are discoloured (by

immersion in alcohol) in the specimens described.

13. Pyrota mariarum,

Rather slender, luteous, the head with the labrum, a transverse spot between the eyes, the eyes themselves,

and sometimes the sides behind, black ; the prothorax piceous or black, with an elongate-triangular

median patch in front, sometimes extending to the base, and the basal margin, luteous; the antenne,

underside, and legs (except sometimes the base of the femora) black; the head and prothorax sparsely

clothed with erect hairs, the elytra also with a few shorter hairs; the metasternum thickly, the rest of

the under surface sparsely, clothed with long hairs. Head with a few widely-scattered punctures, sulcate

on the vertex, the eyes large, feebly emarginate; antenne and palpi as in P. hirticollis; prothorax

slightly longer than broad, very sparsely and finely punctate, with a smooth median space; the rest as

This is an insular form of P. hirticollis, which inhabits the adjacent mainland, but

differs from it in the much sparser and finer punctuation of the head and thorax, and

in having the thorax in great part black ; it is also much smaller and less robust. The

thorax has an elongate-triangular luteous patch on the disc in front, this marking in

two specimens extending to the base, the rest being black or piceous. The legs are

long and very slender. Three males and one female were obtained by Mr. Forrer.

the anterior and middle tarsi are considerably dilated in the male; the outer spur of

the hind tibie is very broad, the inner one acute and slender; the under surface is

clothed with very coarse, long, yellowish hairs ; the sixth ventral segment in the male

is very broadly triangularly excavate along the middle from the deeply-emarginate

apex nearly to the base, the cavity being filled with membrane. The short, stout

antenne, the intermediate joints of which are much thickened, the stout legs, &c.,

distinguish this insect from P. nobilis.

Lytta, Fabricius, Syst. Ent. p. 260.

Cantharis, as adopted here, following Leconte and Horn’s classification of the

North-American Vesicants, includes only those species with the antenne thicker

externally (at least in the female, the intermediate joints often thickened in the male),

the anterior femora and tibize without a silky-pubescent concave space on their inner

face, the labrum feebly emarginate, and the two portions of each tarsal claw equal in

length and separate.

Twenty-five species are here recorded from within our limits, as against thirty-five

from the United States; four only occur south of Mexico. Dr. Horn’s Group III. is

not represented in Central America, and five only of our species (as against eighteen)

belong to his Group IT. There is a good deal of confusion in the synonymy of several

Mexican species, Dugés and Haag having each described certain of them under different

names *.

The form of the sixth ventral segment, and in some cases that of the last dorsal

segment also, in the male, is a very important character for discriminating between the

various species of this genus; but it is not noticed by Haag. In C. quadrimaculata,

Chevr., and C. sanguineoguttata, Haag, the last dorsal segment (or pygidium) has an

elongate process in the male; C. sangwineoguttata also possesses other extraordinary

male characters. C. quadrimaculata, C. biguttata, C. proteus, and C. variabilis vary

very much in colour; of the two latter, varietal forms still “in copula” have been

received from M. Sallé or Herr Hoge. C. dichroa, Lec., is recorded by Dr. Horn

(Proc. Am. Phil. Soc. xiii. p. 112) as from Mexico, but no specimen of it has been

received by us. |

A common insect of the “ tierra templada ” of Mexico and Central America, occurring

chiefly at elevations of from 3000 to 5000 feet. Thisis the largest species of the genus

in Central America, and may be readily known by its black body and partly rufous

head. In the male, joints 4-6 of the antenne are thickened and deformed, greatly

produced on the upper side ; the middle tibie are distorted and compressed, dilated at

the apex, and excavate above and beneath in their outer half; and the sixth ventral

segment is feebly emarginate. In the female the antenne are thickened towards the

tip. The spurs of the hind tibie are stout and obtuse, the outer one much wider than

the other. Varies in length from 14-45 millim. (exclusive of abdomen).

emarginate at the apex. The discal spots on the thorax vary in size, and in one

specimen they are almost obliterated. ‘The outer spur of the hind tibiz is very broad,

the inner one slender.

Of this species we have received ten examples, one only of which is of the male sex.

As Dr. Horn states (Trans. Am. Ent. Soc. xii. p. 108), C. mutilata is allied to C. ery-

throthorax, but differs from it in the entirely rufous thorax, as well as by its male

characters. In the male of C. mutilata the basal joint of the middle tarsi is strongly

dilated internally ; the anterior femora are simple; joint 4 of the antenne is thickened,

5 is deformed and strongly produced on the upper side, and 6 is slightly flattened, but

not wider than 7; and the sixth ventral segment is very feebly emarginate. The

antenne in both sexes are shorter, stouter, and more moniliform than in C. erythro-

thorax, and the thorax is less depressed anteriorly. The outer spur of the hind tibize

is very stout, the inner one acute.

Vera Cruz ® (Sallé).

An extremely variable and abundant insect in Mexico, but not extending south of

the State of Vera Cruz, and only just passing the northern frontier. The males have

joints 4-7 of the antenne thickened, the last dorsal segment (or pygidium) prolonged

in the middle, and the fifth and sixth ventral segments emarginate, the latter very

deeply triangularly so, with the lateral portions considerably produced.

The dorsal process of the male varies not only in width but in shape also: in the

specimens from Orizaba, Esperanza, &c. it is acutely dilated on either side at the apex

(fig. 14a), and in those from Villa Lerdo it is slightly rounded and not at all dilated

at the apex (fig. 15a); but amongst the long series from San Luis Potosi &c.

numerous intermediate forms are to be found, so that no importance can be attached

to this as a specific character. The Villa Lerdo specimens have the elytra black, with

a common median fascia, the sides, base, and apex yellow; in about one-fourth of them

the elytra are entirely black. The San Luis specimens are intermediate as regards the

CANTHARIS, 44]

amount of black upon the elytra between those from Villa Lerdo and those from

Orizaba ; in two examples (from Orizaba and Tacambaro) the elytra are entirely yellow.

We have received about 200 specimens, including large series from Villa Lerdo, San

Luis Potosi, Esperanza, Mexico city, and Zapotlan. In two (? aberrant) females from

Villa Lerdo the sixth ventral segment (instead of being rounded at the tip and entire)

is divided in the middle.

C. alemant, Dugés, seems to be based upon a pallid variety with the thorax smoother

than usual. We figure a typical male (=fasciolata, Jimenez) from Orizaba (fig. 14);

and a male (fig. 15) and a female (fig. 16) of the var. bifasciata, Sturm, the former

from Villa Lerdo, the latter from Toluca. .

Lytta corallifera, Haag, Berl. ent. Zeitschr. 1880, p. 35°; Sturm, Cat. p. 174°.

Hab. Mexico! ? (Sallé, ex coll. Sturm; coll. F. Bates), Sierra de San Miguelito

(Dr. Palmer).

“ Elongata, nigra, nitida, macula frontali, margine posteriore capitis, lateribus thoracis femoribusque rufo-

sanguineis, elytris reticulatis, humeris fere levibus ; subtus opaca.—Long. 19-25, lat. 7-9 millim.”

Four examples of this species are before me, all males. In this sex, joints 4-6 of

the antenne are moderately thickened; the basal joint of the middle tarsi is slender ;

the fifth ventral segment is broadly, deeply emarginate; and the sixth segment is

very deeply, circularly excised at the apex, the excision extending to beyond the middle

of the segment. The elytra (as in the allied C. magister, Horn, from Arizona, &c.)

are very coarsely reticulated.

In the specimens we have received the femora are black at the base and apex. The

outer spur of the hind tibie is stout, the inner one acute. In the form of the sixth

ventral segment in the male C. corallifera approaches C. cribrata, Lec.

7. Cantharis intricata. (Tab. XX. figg. 18, ¢; 18, sixth ventral seg-

ment, 3.)

Elongate, rather broad, black, a large patch between the eyes and the sides of the prothorax to a greater or

less extent reddish-yellow, the head and prothorax shining, the elytra opaque. Head with a few very

widely scattered fine punctures, the eyes large; antennz stout, moderately long in the male, shorter

in the female, thickening a little towards the tip, the outer joints ovate; prothorax broader than long,

. strongly rounded at the sides anteriorly and narrowed behind, with an interrupted median groove and a

broad shallow depression on either side of the disc about the middle, the surface with a few very widely

scattered fine punctures ; elytra about twice as wide as the prothorax, closely and rather finely reticulate ;

beneath opaque, thickly and finely punctured, the metasternum pubescent; the outer spur of the hind

tibia broad, spoon-shaped, the inner one slender.

g. Antenne with joints 4-6 slightly thickened ; fifth ventral segment broadly, the sixth segment triangularly,

emarginate.

Length 16-22, breadth 5-7 millim. (¢ 9.)

442 HETEROMERA.

Hab. Mexico, Villa Lerdo in Durango (Hoge).

This species agrees very closely with Dr. Horn’s description of C. cribata, Lec., from

Texas, but has different male-characters. In C. cribrata, 3, the sixth ventral segment

is semicircularly notched, and the intermediate joints of the antennz are not thickened.

C. intricata is closely allied to C. corallifera, but may easily be known from it by the

much finer reticulation of the elytra, the entirely black legs, the black head (the imtra-

ocular spot excepted), and the very different form of the sixth ventral segment in the

male. Numerous examples.

ment, 3.)

Lytta sanguinea, Haag, Berl. ent. Zeitschr. 1880, p. 35".

Hab. Mexico (coll. Haag*), Mochitlan in Guerrero (Baron).

“Tota rufa, elytris pallidioribus, antennarum apice marginibusque segmentorum nigris; capite thoraceque

canaliculatis, sparsim punctatis; elytris dense diffuse ruguloso-punctatis, nervatis; pectore pedibusque

breviter flavo-pilosis.—Long. 27, lat. 74 millim. (cap. exc.).”

We are indebted to Mr. Harford for a male example of this species. C. sanguinea

approaches C. erythrothorax &c., but has joints 4-6 of the male antenne merely

thickened. The male also has the basal joint of the middle tarsi strongly dilated on

the inner side, concave beneath; the fifth ventral segment unemarginate ; and the

sixth segment depressed and smooth in the middle, and feebly emarginate at the apex.

The elytra are rather coarsely scabrous-punctate, with three well-marked raised lines

or coste. The thorax is as long as broad, the disc deeply transversely depressed before

the middle. The outer spur of the hind tibie is very stout, the inner one slender.

Haag’s description | was made from a single (female) example.

9. Cantharis erebea. (Tab. XX. figg. 20,6; 20a, sixth ventral segment, ¢.)

Elongate, black, a small fulvous spot between the eyes excepted, moderately shining, the elytra opaque. Head

with a few very widely scattered fine punctures, the occiput impressed in the middle and more coarsely

and closely punctate, the eyes rather small; antenne moderately elongate, gradually thickening outwardly,

the outer joints oblong-ovate, the eleventh very much longer than the tenth; prothorax as long as broad,

rather convex, subquadrate, the sides rounded in front, the disc transversely depressed before the base,

and with an interrupted median groove and a deep fovea on either side a little behind the middle, the

surface with a few very widely scattered fine punctures; elytra elongate, finely scabrous-punctate, and

with two very faint raised lines on the disc; beneath shining, very sparsely, finely punctate, the meta-

sternum sparsely pubescent ; outer spur of the hind tibia very broad, truncate at the tip, the inner one

acute.

6. Antenne with joints 4—7 dilated and thickened, the fifth strongly so; the middle tibiz distorted and

compressed towards the tip; the basal joint of the middle tarsi thickened; the sixth ventral segment

depressed and smooth in the middle and very feebly emarginate at the apex; the last dorsal segment

broadly rounded at the tip.

Length 19-25 millim. (¢ 2.)

Hab. Mexico (Sallé), Huetamo in Michoacan (Hoge).

CANTHARIS, 443

Four examples, one only of which is of the male sex. This insect nearly agrees with

Dr. Horn’s description of C. melena, Lec. (Proc. Am. Phil. Soc. xiii. p. 105), from

Sonora and Arizona; but C. melena, 3, has the last dorsal segment acutely oval at

tip, and the sixth ventral segment deeply emarginate.

10. Cantharis ebenina.

Hab. Mexico ? (Boucard 1), State of Vera Cruz (Boucard?), Boca del Monte (Flohr 2),

Matamoros Izucar, San Andres Tuxtla (Sallé), Esperanza (Hége).

Found in abundance by Herr Hoge at Esperanza. ‘This insect is of a uniform dull

black colour; the head and thorax are very finely, sparsely, irregularly punctate, the

disc of the latter almost smooth; the elytra are very finely scabrous-punctate; the

outer spur of the hind tibiz is moderately stout, the inner one slender. The male has

joints 4-6 of the antenne a little thickened and the sixth ventral segment feebly

emarginate.

C. ebenina is closely allied to C. tenebrosa, Lec., from California, but is smaller and

less elongate, and has the head and thorax much more finely punctured and the elytra

smoother ; the sixth ventral segment is feebly emarginate in the male in both species.

Varies in length from 7-15 millim.

11. Cantharis plumbea.

Lytta plumbea (Klug), Haag, Berl. ent. Zeitschr. 1880, p. 38°.

Hab. Mexico (coll. Haag*), Canelas in Durango (Becker).

‘ Elongata, opaca, obscure eenescens ; capite dense punctato, postice canaliculato; thorax rugulis minutissimis

elytris latis, humeris distinctis, rugulosis. Long. 12-18, lat. 4-44 millim.”

Six examples from Durango agree very nearly with this diagnosis. They are dull

black, with a slight brassy lustre ; the head and thorax coarsely, rugosely punctate, the

latter transverse, somewhat rounded at the sides, transversely depressed anteriorly, and

with a depression on either side of the disc behind ; the elytra finely scabrous-punctate,

flattened on the disc, and vaguely sulcate towards the base; the antenne stout, with

joints 4-6 a little thickened in the male; the outer spur of the hind tibiee moderately

stout, the inner one slender. The male has the fifth ventral segment broadly and

shallowly, the sixth very deeply, emarginate.

444 HETEROMERA.

Hab. Mexico, Mochitlan in Guerrero (Baron), Amula in Guerrero (H. H. Smith),

Jalapa (Hoge), Cordova, Oaxaca (Sallé).

Of this species, the locality for which is not mentioned by its describer', we have

received fifteen examples. The head is black or bronze-black, the thorax reddish-yellow,

with a small black spot on either side of the middle of the disc, the elytra cyaneous or

green. The head and thorax are shining, very sparsely, finely punctate, the latter

transverse, rounded at the sides, more or less distinctly canaliculate, and transversely

depressed in front; the elytra are finely scabrous-punctate ; the antenne are short and

stout, with submoniliform joints, the fourth and fifth thickened in the male; the outer

spur of the hind tibie is stout, the inner one slender. The sixth ventral segment is

very deeply, the fifth broadly and arcuately, emarginate in the male. Varies in length

from 10-17 millim. A specimen from Jalapa is figured.

Hab. Mexico, Uruapan??, Moroleon ®, and Valley of Mexico? (Dugés), Mexico city

(Dr. Palmer), Guanajuato, Toluca (Sal/é); Panama (coll. Haag *).

Both Haag and Dugés seem to have confused two closely allied species under one

name; the variety they mention differs constantly from the type in the very much more

deeply emarginate sixth ventral segment in the male.

In C. koltzei, 3, the sixth ventral segment is depressed in the middle and rather

deeply triangularly emarginate ; the fifth segment is feebly emarginate; and joints 4-6

of the antenne are thickened. C. koltzei also has the head and thorax duller and more

closely punctured, the thorax more transverse. Dugés* gives the colour as black,

Haag! as “eenescent.” ‘The six specimens before me (four @ and two ¢, including

one named by Dugés) have a faint violaceous lustre.

Both species occur in the vicinity of the city of Mexico.

In the male of this insect the sixth ventral segment is very deeply emarginate (the

emargination extending to three-fourths the length of the segment), with the lateral

processes considerably prolonged ; the fifth segment is deeply arcuate-emarginate ; and

: CANTHARIS. 445

joints 4-6 of the antenne are slightly thickened. C. cyanescens also differs from C. koltzez

by its cyaneous or greenish colour, and by the more shining, less closely punctured head

and thorax, the latter less transverse. Six males and two females of C. cyanescens

are before me.

15. Cantharis humilis.

tibus albidis tectis. Long. 8-10, lat. 2-24 millim.”

This species is said to be closely allied to C. koltzei ; we have not received a specimen

of it. Apparently described from a single female example.

16. Cantharis subviolacea.

Cantharis augusti, Deyr. in litt.

Moderately elongate, obscure violaceous, the head and prothorax of a more neous tint, sparsely pubescent,

shining, the elytra opaque. Head sparsely, rather coarsely punctate, the eyes large; antenne short and

stout in both sexes, thickening outwardly, the joints moniliform; prothorax transverse, narrowed before

and behind, canaliculate in the middle, the sides, base, and apex very sparsely and rather coarsely punc-

tate, the disc almost smooth; elytra finely scabrous-punctate ; beneath sparsely, finely punctured ; the

outer spur of the hind tibiz stout, the inner one slender.

from C. variabilis in the much more finely and sparsely punctured head and thorax, and

in its violaceous colour.

one-fourth from the apex. In some of the Guanajuato specimens, several of which are

before me, this spot is replaced by two longitudinal streaks (as shown in Dugés’s figures

2 and 2G); in one from Villa Lerdo, obtained with the typical North-American form,

the elytra are black, with the sides anteriorly and the apex yellow (as in Dugés’s

figure 2J). In the male, joints 4—6 of the antenne are moderately thickened, the fifth

ventral segment is broadly, feebly emarginate, and the sixth segment is very deeply,

triangularly emarginate, the apex acutely produced on either side (as in Dugés’s

figure 2g). An abundant insect in New Mexico and Arizona, according to Dr. Horn ?®.

18. Cantharis scitula. (Tab. XX. figg. 25, ; 25a, sixth ventral segment, ¢ .)

Moderately elongate, brassy-black, the elytra with the lateral margin and a broad median vitta extending from

the base nearly to the apex yellow, the tibie and tarsi in part, and a spot on the hind femora, testaceous ;

sparsely and rather coarsely pubescent, shining. Head sparsely, coarsely punctate; antenne rather

short, the outer joints oblong-ovate; prothorax subcampanulate, almost parallel at the sides behind, fully

as long as broad, transversely depressed before the middle, feebly emarginate in the centre at the base,

sparsely, coarsely, irregularly punctate, a longitudinal space in the middle impunctate; elytra rather

coarsely scabrous-punctate ; beneath sneous, thickly punctured, the outer spur of the hind tibis broad,

the inner one slender.

Moderately elongate, black or pitchy-brown, the prothorax with an ill-defined patch on the middle of the disc

in front and sometimes the sides also anteriorly, a small lateral spot excepted, reddish-yellow, the sides of

the elytra anteriorly and a spot between the eyes sometimes of the same colour ; somewhat thickly and

coarsely pubescent, shining, the elytra subopaque. Head coarsely and rather thickly punctured ; antennx

moderately long in the male, shorter in the female, the outer joints oblong-ovate ; prothorax convex,

almost as long as broad, emarginate in the centre at the base, transversely flattened anteriorly, rounded

at the sides in front, almost parallel behind, sparsely, coarsely punctate, the disc with a smooth space on

either side of the middle; elytra finely scabrous-punctate, and with two faint raised lines on the disc ;

beneath thickly punctured and pubescent; outer spur of the hind tibie broad, obliquely truncate at the

tip, the inner one acute.

3. Antenne with joints 4 and 5 flattened and dilated, 6 a little stouter than 7: fifth ventral segment

joints in the male. The longer antenne in both sexes and the less transverse thorax

distinguish it from C. variabilis, Dugés, apart from the different male-characters; and

the coarsely punctured head and thorax &c. separate it from C. michoacane, C. bigut-

tata, &c. The thorax in two specimens shows traces of four spots in a transverse line

across the middle, a system of coloration not visible in any of the varietal forms of

C. proteus or C. variabilis.

A variety of this species with the thorax reddish-yellow with two black spots on the

disc occurs at Guanajuato, the thorax in the typical form being entirely black : copulated

specimens of the two forms have been received by us from M. Sallé. The head and

thorax are coarsely punctured, the latter transverse, rounded at the sides anteriorly,

feebly emarginate in the centre at the base, obsoletely canaliculate, and with a smooth

bare spot on either side of the disc at the middle; the ‘elytra are finely scabrous-

punctate ; the antenne are comparatively short, gradually thickened outwardly in both

sexes, the joints moniliform; the outer spur of the hind tibiz is very stout, the inner

one acute. The male has the sixth ventral segment very feebly emarginate. C. varia-

bilis is possibly synonymous with C. puberula, Lec., as noted by Dr. Horn (Trans. Am.

Ent. Soc. xii. p. 107); but till the male of Leconte’s species is discovered it is impos-

sible to speak with certainty. C. variabilis is the only one of several allied Mexican

forms to which Leconte’s description will apply.

921. Cantharis michoacanez.

Moderately elongate, brassy-black, the prothorax reddish-yellow with a small black spot on either side of the

middle of the disc, sparsely pubescent, shining, the elytra opaque. Head very sparsely, coarsely punctate,

the eyes large ; antenne rather short, thickening outwardly in both sexes, the outer joints ovate; pro-

thorax as long as broad, emarginate in the centre at the base, the sides rounded in front and almost

parallel behind, the disc transversely depressed anteriorly, the surface very sparsely punctured ; elytra

finely scabrous-punctate; beneath somewhat thickly punctured ; the outer spur of the hind tibize mode-

rately stout, the inner one acute.

We have received about seventy examples of this variable species, including a pair

still “in copula” from Herr Hoge (from Matamoros Izucar), whereof the male belongs

to C. sobrina and the female to C. bipartita, Dugés. Haag! enumerates five colour-

varieties of this insect, specimens of all of which are before me, including some deter-

mined by himself; these are as follows :—(1) Tota nigra, interdum obscure enescens,

puncto capitis rufo (=sobrina, Dugés) ; (2) Thorace rufo, bipunctato ; (3) Capite rufo,

ante oculos nigro-bipunctato, thorace rufo, bipunctato; elytris rufis, apice nigris (=07-

partita, Dugés) ; (4) Idem, sed capitis nigrescente, rufo-punctato ; (5) Idem, sed humeris

solis rufis. ‘The head and thorax are coarsely punctured, the latter as long as broad

and with a smooth spot on either side of the disc about the middle; the antenne are

gradually thickened to the tip in both sexes, moderately long in the male, shorter in

the female; the elytra are rather coarsely scabrous-punctate ; the outer spur of the hind

tibie is broad, the inner one slender. In the male the fifth ventral segment is broadly,

and the sixth segment very deeply and acutely, emarginate, the lateral processes of the

sixth elongate.

tate, with intermixed larger punctures; the head is sparsely, finely punctate; the thorax

is rather broader than long, subquadrate, deeply transversely depressed in the middle

behind and shallowly so in front, and finely punctured at the sides, base, and apex; the

antenne are short and stout, and thickened outwardly in both sexes; the spurs of the —

hind tibie are very slender, subequal, and yellow in colour. The male has a single

spur to the anterior tibie, and the sixth ventral segment crescentically depressed and

triangularly emarginate.

We have received a pair of this remarkable species from Mr. Becker.

Hab. Guaremata (coll. Haag and mus. Vindob.1; Sailé), Calderas (Champion),

Chimaltenango, Tepan (Conradt).

A narrow, elongate species, of an obscure violaceous, green, or eneous colour, the

thorax with a rufous lateral patch, which is often obsolete; the legs and antenne

elongate. The thorax is shining, impunctate, longer than broad, the sides obliquely

converging from the middle forwards ; the elytra are very finely scabrous-punctate ; the

hind tibial spurs are slender, equal. The male possesses extraordinary characters,

which were mostly overlooked by Haag :—antenne with joints 4-7 greatly elongated ;

anterior and posterior trochanters with a slender acute spine on their lower face ; first

joint of the middle tarsi with a long, slender tooth on the inner side at the base, this

tooth placed at right angles to the joint; last dorsal segment (or pygidium) with an

elongate process in the middle at the apex, this process triangularly dilated at the tip,

the apex of the segment semicircularly excised on either side of it; sixth ventral seg-

ment very broadly and deeply excavate from the middle to the apex, deeply triangularly

emarginate. In the female the antenne are very gradually thickened outwardly, joints

4-10 slightly decreasing in length.

STATIRA (p. 3).

40 (a). Statira pilifera.

és Elongate, obscure rufo-testaceous, the elytra reddish-brown with an neous lustre, the upper surface

moderately shining, the legs, antenne, and under surface rufo-testaceous ; the elytra clothed with very

long, erect hairs. Head finely, sparsely punctate, almost smooth in front, the eyes very large, rather

the fourth, sixth, and eighth interstices also with four or five setiferous punctures towards the apex ;

beneath almost smooth ; legs elongate, rather slender, the femora glabrous on their inner edge.

Length 103, breadth 3 millim.

Hab. Mexico, Cerro de Plumas (Flohr).

One specimen. Allied to S. alternans, but easily distinguishable from it by the

longer and more shining thorax, and the more numerous setiferous impressions on the

elytra, these being arranged in double rows on each of the alternate interstices, the

first excepted. SS. pilifera somewhat resembles S. cribrata and S. ciliata, but it has

the thorax completely margined at the sides and the legs without long hairs.

41 (a). Statira spiculifera, (Tab. XXI. fig. 3, 3.)

g. Elongate, the head and prothorax dull, ferruginous, the elytra shining, obscure ferruginous, with the

sides brilliant metallic green, the antennz, legs, and under surface reddish-testaceous. Head finely and

rather densely punctured, almost smooth in front, the eyes very large; antenne moderately long, not

very slender, the apical joint nearly equalling joints 6-10 united ; prothorax as long as broad, completely

margined at the sides, the sides somewhat obliquely converging in front, the anterior angles rounded, the

preceded by a feeble elevation, these elevations becoming more distinct towards the sides ; legs moderately

stout ; hind femora sinuate on their inner edge, densely ciliate towards the base; hind tibie sinuate.

Length 10, breadth 33 millim.

Hab. Mexico, Motzorongo in Vera Cruz (Lohr).

One specimen. Allied to S. tuberosa and S. nodulosa, but less elongate, with the

legs shorter and stouter, the thorax not so smooth, the elytra more shining, &c. The

elytral sculpture resembles that of S. nodulosa, but the punctures of the alternate

interstices do not bear long, erect hairs.

63 (a). Statira flohri.

Moderately elongate, rather depressed, very shining, piceous or pitchy brown, the head and the base and apex

of the prothorax ferruginous in one example, the elytra metallic green, seneous or cupreo-sneous at the

tip. Head very finely, sparsely punctured, the eyes comparatively small and very widely separated in

the female, larger in the male ; antenns rufo-testaceous, long, very slender, thickening outwardly, the

apical joint in the female about three times as long as the preceding one (in the male broken off);

prothorax as long as broad, very finely margined at the sides, the latter a little rounded anteriorly, the

anterior angles obtuse, the disc transversely depressed on either side behind the middle, the surface very

finely, sparsely punctured’ elytra moderately long, transversely depressed below the base, finely and

rather deeply striate, the stria with exceedingly closely placed fine punctures, the interstices almost flat,

the first with four (near the apex), the third, fifth, seventh, and ninth each with from six to eight (widely

scattered) rather fine punctures ; beneath almost smooth: legs long and slender, pitchy-brown, the tarsi

paler, the femora and tibie with a few very long, scattered, projecting hairs.

Length 9-10, breadth 3-33 millim. (¢ 9.)

Hab. Mexico, Juquila (Lohr).

Two specimens, the male with mutilated antenne. This species resembles

S. ewrata, but it has longer and much more slender antenne, smaller eyes, &c The

femora and tibiz bear a few very long projecting hairs, and S. flohri, following the

arrangement here adopted, should be placed near S. pilipes and its allies, from all of

which it differs in the completely margined thorax. The long hairs on the femora

and tibie are easily abraded.

Mr Flohr informs me that he has also met with this insect at Cerro de Plumas.

formed by four partly confluent longitudinal streaks on each elytron, and nearly

enclosing three oblong spots; it also has the eyes smaller, and the antenne shorter

and more slender.

Length 73 millim.

Hab. Mexico, Atoyac in Vera Cruz (Flohr).

One specimen, apparently a female. This species is not very closely allied to any

of the other members of the genus described in this work; it resembles Copidita

trifoveata in colour, from which it may be known by the simple mandibles, shorter

antennes, flatter thorax, &c. The thorax is considerably dilated anteriorly, narrow

and parallel behind.

XYLOPHILUS (p. 166).

Since the publication of the preceding pages, Mr. Flohr has paid especial attention

to this genus in Mexico, his investigations resulting in the discovery of numerous

interesting new species. He informs me that all his specimens have been beaten

from oak trees, especially those with large leaves. Xylophilus, so extraordinarily rich

in species within our limits, is one of the most interesting genera that I have had to

deal with in this work.

abruptly bowed inwards at about one-third from the apex, the anterior pair armed with a long sharp

tooth at the inner apical angle; hind tibie slightly curved ; intermediate femora thickened on the inner

side towards the tip; hind femora broadly widened, grooved along the inner side, the concavity filled

with short fulvous hairs,

Length 33 millim.

Hab. Mexico, Tlalpam (flohr).

Mr. Flohr informs me that he has only been able to secure three specimens of this

fine species as yet, two males and one female. The description is taken from one of

the former. The female, he says, is larger and more robust, and has shorter and

stouter antenne, and straighter tibie. X. mexicanus is allied to X. humeralis and

X,. curvipes; but it is much larger and very much more elongate, the eyes are less

approximate (in ¢ ), the upper surface is more coarsely punctured, &c. The antenne

resemble those of X. humeralis (3), but their apical joint is still more elongate.

This is one of several species of Xylophilus occurring on oaks at Tlalpam, eleven

miles from the city of Mexico.

15 (a). Xylophilus flavipalpis. (Tab. XXI. fig. 7, ¢.)

3. Rather short and robust, pitchy-black, shining, somewhat thickly clothed with long, moderately coarse,

densely punctured, the punctures coarse on the elytra, finer on the head and prothorax, not hidden by

the pubescence. Head very large, rather narrowly extended on either side behind the eyes, the latter

hairy, exceedingly large and narrowly separated ; antennee very hairy, moderately stout, not extending

to the middle of the elytra, joint 3 longer than 2, 3-10 about equal in length and increasing slightly in

width, longer than broad, 11 twice as long as 10, stout, ovate, obliquely acuminate ; prothorax convex,

nearly as long as broad, distinctly wider at the base than at the apex, the sides straight, feebly rounded

in front, the disc feebly, transversely depressed on either side before the middle; elytra rather short,

more than twice as wide as the prothorax, gradually narrowing from about the middle, the disc with a

shallow oblique groove extending from the shoulders inwards, the suture depressed at the base ; legs very

hairy, moderately long ; the anterior and posterior femora very stout, the intermediate pair moderately

so, the hind pair unarmed ; anterior tibia sinuous within, slightly bowed inwards at the tip, and armed

with a long sharp tooth at the inner apical angle.

One male example. Closely allied to X. atricolor, from the State of Panama; but

larger and broader than the male of that insect (the head and elytra wider in propor-

tion to the width of the thorax), the head and thorax more densely punctured, the

latter a little wider at the base, with the sides less parallel, the elytra obliquely

depressed on the basal portion of the disc, the anterior femora stouter and the anterior

tibize less bowed in the male. |

equalling the width of the eye as seen from above; antennw—( g ) moderately elongate, rather slender,

joint 3 much longer than 2, 3-10 about equal in length and increasing slightly in width, longer than

broad, 11 stout, twice as long as 10, ovate, obliquely acuminate—( @ ) a little shorter, with the penultimate

joints as broad as long and the apical one shorter ; prothorax broader than long, moderately convex, the sides

parallel behind, rounded in front, the disc almost unimpressed ; elytra rather short, narrowing from about

the middle, about twice as long as broad, without oblique groove on the disc anteriorly ; legs moderately

long, slender, the femora a little thickened, the hind pair stout in the male, more slender in the female ;

anterior tibie feebly sinuate within and armed with a very short, fine tooth at the inner apical angle in

the male.

Hab. Mexico, Tlalpam (Flohr); Guatema.a, Quiche Mountains 8000 feet (Champion).

Four examples. The single ( ¢ ) specimen from Guatemala was doubtfully referred by

me (ante, p. 178) to X. funereus; from which the present species may be known

by its less elongate, less parallel shape, rather more widely separated eyes, and differently

coloured legs and antennee—these organs being entirely black in X. funereus. ‘The dark

tarsi &c. will distinguish X. geniculatus from X. atricolor and X. flavipalpis.

Xylophilus bicolor (p. 182).

To the Mexican locality given, add:—Near the city (Hoge), Tlalpam, Amecameca

(Mohr).

Found in numbers by Mr. Flohr on oaks near the city of Mexico. This species

varies greatly in the colour of the elytra, from black with a flavo-testaceous or testaceous

humeral patch (as in the type) to entirely testaceous. The following forms may be

noticed :— |

(1). Elytra black, with a transverse, rounded, or oblique humeral patch testaceous.

(2). Elytra piceous or brown, with an oblique patch extending from the shoulders downwards and a large

patch of variable size on the disc beyond the middle testaceous *, these markings sometimes confluent.

(3). Elytra entirely testaceous.

* The Mexican Xylophilus mentioned by me, antéa, p. 190, nota, belongs to this form of X. bicolor.

with the basal three joints yellow; the legs flavo-testaceous, with the hind femora (except at the base)

black, and the hind tarsi and the apical third of the hind tibie infuscate; the under surface (the head

and prothorax excepted) black; the entire upper surface thickly, moderately coarsely punctured, and very

finely, sparsely pubescent, the pubescence not hiding the punctuation. Head rounded at the sides behind

the eyes, the latter moderately large and rather widely separated; antenne slender, thickening out-

wardly, very elongate, joint 2 stout, about half the length of 3, the latter shorter than 4, 4-10 not

differing much in length, longer than broad, 11 stout, twice as long as 10, ovate, obliquely acuminate ;

prothorax as long as broad, convex, with the sides parallel behind and slightly rounded in front, the disc

with a very feeble arcuate depression in the middle behind; elytra nearly twice as wide as the

prothorax, moderately long, parallel in their basal half, obliquely depressed on the disc below the base ;

legs moderately elongate, slender ; the hind femora with a narrow pouch-like appendage along their inner

edge ending abruptly a little before the apex (thus appearing angularly dilated), and a large rounded

prominence on their anterior face towards the tip—this prominence being formed by a rounded lamellate

process, which is abruptly twisted and bent downwards, and is only partly visible from above,—their lower

face deeply concave beneath this ; the intermediate tibie deeply triangularly notched on their outer edge

near the apex.

Hab. Mexico, Amecameca in Morelos (Flohr).

One specimen only of this extraordinary insect has been received. X. appendiculatus

is coloured exactly like the typical form of X. dicolor, which occurs at the same locality ;

but differs from it in its more elongate, more parallel shape, very elongate antenne, and

extraordinary male characters. The hind femora( dé ) are greatly thickened towards the

apex. X. guadrisignatus is the only other species of the genus known to me with the

hind femora thickened on their anterior face in the male sex.

paler, the elytra obscure testaceous, with the apex and a rather broad oblique streak on the disc of each

beyond the middle brown, the antenne, palpi, and legs testaceous ; the upper surface finely, rather densely

pubescent, the pubescence partly hiding the punctuation. Head rather broad, minutely punctured,

narrowly extended on either side behind the eyes, the latter very large, somewhat narrowly separated ;

antenne long and slender, joint 2 very short, not half the length of 3, 3-5 very elongate (the other joints

behind and a transverse groove on either side about the middle; elytra moderately long, about twice as.

wide as the prothorax, widest beyond the middle, parallel anteriorly, depressed along the suture at the

base, and with a shallow oblique groove on the disc extending from the shoulders inwards; legs very

slender, moderately long.

Length 2 millim.

Hab. Mexico, Real del Monte 9300 feet (Lohr).

One female example. This species comes near the preceding, X. odliquus, but has

the first and second joints of the antenne stouter, the second not so short, the third not

twice the length of the second. The insect is of a uniform piceous colour, clothed

with rather long ashy pubescence. The slender limbs, deeply foveate thorax, &c.,

separate it from X. funereus and its allies.

Xylophilus argentatus (p. 186).

Mr. Flohr has sent us the fragmentary remains of a Xylophilus from Jalapa, Mexico,

which belong to X. argentatus or to a closely allied species. This insect has a brown

spot on the disc of each elytron close to the base (of which there is no trace in

X. argentatus) and a triangular blackish-brown patch beyond the middle, this patch

very deeply excised in the middle behind; the rest of the upper surface very densely

clothed with bluish-white pubescence.

31 (a). Xylophilus lactineus. (Tab. XXI. fig. 12.)

Elongate, rather narrow, parallel, black, very densely clothed with fine, scale-like, closely appressed, bluish-

white pubescence; the elytra each with a rounded black patch on the disc beyond the middle, this patch

slightly excised in the middle behind; the upper surface thickly and finely punctured, the punctuation

hidden by the pubescence. Head as in X. argentatus; antenne thickening a little at the apex, black,

the two basal joints testaceous in one example, joint 2 scarcely shorter than 3, 5-10 subtriangular,

decreasing in length, 9 and 10 about as broad as long, 11 much longer and stouter than 10, ovate,

acuminate; prothorax as broad as long; elytra elongate, subparallel; legs slender, piceous, the tarsi

paler, the femora and tibi clothed with bluish-white pubescence.

Length 24-23 millim. (9.)

Hab. Mexico, Amecameca in Morelos (fohr).

460 SUPPLEMENT.

Two specimens. ‘This species is closely allied to X. argentatus, but differs from it in

having the dark patch on each elytron rounded (instead of triangular), not extending

forwards at the side in front, and only feebly emarginate behind; the antenne are a

little thickened at the tip, and their second joint is very little shorter than the third.

Mr. Flohr informs me that the insect also occurs in the vicinity of the city of Mexico.

32 (a). Xylophilus silaceus. (Tab. XXI. fig. 13, ¢ .)

Moderately elongate, rather broad, subopaque, pitchy-brown, or obscure brownish-yellow with the prothorax

ferruginous, the head a little darker; the upper surface clothed with very fine, appressed, pruinose

pubescence, which almost hides the punctuation; the head and prothorax exceedingly minutely, the

elytra very finely, punctate. Head moderately large, rounded at the sides behind the eyes, the latter

very small in both sexes; antennz fusco-testaceous, slender—( ¢ ) very elongate, thickening outwardly,

joint 2 short, about half the length of 3, 3-8 very long, increasing in length, 9 and 10 a little shorter

than 8,11 longer and stouter than 10, ovate, acuminate—( ?) shorter, with the penultimate joints

much less elongate; prothorax about as long as broad, compressed at the sides about the middle, and with

a deep oblique groove on either side of the disc behind, the grooves separated by a short carina; elytra

parallel in their basal half, with an oblique depression on the disc extending from the shoulders inwards ;

legs fusco-testaceous, elongate, slender, the femora and tibize simple in both sexes.

Length 12-2; millim. (¢ @.)

Hab. Mexico, Tlalpam (flohr).

Three specimens, two males and one female. In its fine pruinose pubescence this

species resembles X. sericeus; but it is more elongate than that insect, and has a

smaller head, small eyes, and more elongate legs, the hind femora simple in both sexes.

_X. silaceus is perhaps nearest allied to X. singularis, with which it nearly agrees in the

form of the head, antenne, and legs.

CNOPUS.

Head very broad ; eyes rounded, entire, prominent, moderately large, coarsely granulated, separated by a space

equalling the width of the prothorax; antennz elongate, with the second and third joints subequal in

length and thickness; prothorax transverse, very much narrower than the head, with a deep, transverse

groove before the base, and an oblique one on either side towards the apex; elytra short, broad, mode-

rately convex, a little rounded at the sides; first and second ventral segments connate; legs very short

and slender; the tarsi with their penultimate joint minute, their basal joint very short, scarcely longer |

than the following two joints united; the other characters as in Xylophilus.

The above generic name is proposed for a very minute insect from.Mexico, of which

we have received a single male example.

It differs from Xylophilus in having the basal joint of all the tarsi very short, scarcely

longer than the following two joints united. The legs themselves are also much shorter

than in that genus. The thoracic grooves are very deep and sharply defined.

1. Cnopus flohri. (Tab. XXI. figg. 14,3; 144, antenna; 144, hind leg.)

g. Very short, moderately broad, shining; the head (the eyes excepted) and prothorax rufo-testaceous, the

elytra black, the antennw, palpi, and legs testaceous, the under surface (the head and prothorax excepted)

black; the upper surface very sparsely pubescent, the pubescence not hiding the sculpture. Head with a

HETEROMERA. 461

few very minute scattered punctures, very narrowly, subangularly extended on either side behind the

eyes; antenne about three-fourths the length of the body, comparatively stout, thickening a little

outwardly, joint 2 moniliform, shorter than 1, 3 as stout as 2, and about equal to it in length, 3-10

gradually increasing in length and width, all longer than broad, 11 ovate, acuminate, nearly twice as long

as 10; prothorax transverse, moderately convex, the sides parallel behind and rounded and converging in

front, the disc with a very deep, sharply defined, transverse groove before the base (extending across four-

fifths of the entire width of the prothorax, and abruptly limited on either side), and an equally deep

oblique groove on either side anteriorly, the surface with minute scattered punctures; elytra sparsely,

moderately finely punctate, without trace of depression on the disc; femora unarmed, the tibiz almost

straight.

Length 1 millim.

surface with a few, widely scattered, fine punctures, the disc foveate in the middle behind: elytra parallel

finely and moderately densely punctate, with a few widely scattered coarser punctures, the dise with

three feebly raised lines.

Var. The elytra, except at the base, more densely punctured and duller.

Length 94-18 millim. (¢ 9.)

Hab. Mexico, Villa Lerdo in Durango, Chihuahua City, Monterey in Nuevo Leon

(Hoge).

Capt. Casey, to whom I have ‘communicated a specimen (¢ ), informs me that this

insect cannot be treated as a variety of P. terminata, Lec., nor of P. concinna, Casey.

According to him, it is somewhat intermediate, but differs from both by the structure of

the maxillary palpi of the male and by the elytral maculation.

Pyrota divirgata (p. 433). (Tab. XXI. figg. 16, 17, 3, varr.)
