(SUPPLEMENT To Vou. VI. Parr 1.)

Since the publication of this portion of the Phytophaga was commenced in June

1880 a great number of accessions have been added to the collections placed at my

disposal for examination. These relate chiefly to the earlier groups, those referable to

the later ones having been duly inserted in their places. The additions therefore in

all the Families from the commencement to the Eumolpide are very numerous and

will render this part of the Supplement much more extended than that relating to the

large Families which follow. The collection of M. Sallé had not then been acquired ;

and Mr. Champion had only been working for a short time in Guatemala, and his

explorations in the State of Panama had not been commenced. Most of the additions.

derived from Herr Hége’s second Mexican expedition have also still to be dealt with.

These and many smaller consignments received from time to time have all swelled the

materials which I now propose to examine.

2 PHYTOPHAGA.—SUPPLEMENT.

An examination of Kirby’s type of O. childrent in the British Museum has proved

to me that the Sonoran examples are conspecific with it. Kirby's description is,

however, based upon an immature specimen in which the thorax (instead of being

black, as in all the examples from Mexico before me) is fulvous with the disc obscure

piceous, and the elytra are of a greenish colour. In the North-Mexican specimens the

pattern of the elytra and other characters agree well with the type. The figure given

by Kirby fairly represents the species, which may be known by the narrow black

suture and the laterally widened transverse black band below the middle of the elytra.

AULACOSCELIS (p. 1).

Of this interesting genus, which up to the present time has included only three

species, many others have since been received from Central America. Amongst the

latter are two or three which may hereafter have to be removed to another genus, as

they differ considerably from the typical forms in the structure of the antenne and in

the shape of the head and thorax.

These new species, however, possess all the more constant structural characters of

Aulacoscelis, such as the more or less well-marked longitudinal grooves at the sides of

the base of the thorax, and the rather flattened and depressed appearance of the elytra,

and I accordingly refer them to it.

Aulacoscelis melanocera (p. 1).

To the locality given, add :—Mexico, Oaxaca (Hége), Northern Yucatan (Gawmer) ;

GUATEMALA, Chacoj, Panzos (Champion); Costa Rica (Van Patten); Panama, Volcan

de Chiriqui (Champion).

Aulacoscelis candezei (p.1). (Tab. XXXV. fig. 7.)

Black or piceous ; above fuscous, the elytra margined with fulvous.

Var. a. Head, thorax, and elytra nearly black. |

Var. 6. Above fulvous.

Length 34 lines.

To the locality given, add:—Mexico, Cerro de Plumas, Ventanas (Hége), San

Miguel del Rio (Sallé).

I have no doubt that I refer rightly the Mexican specimens before me to this

species, and | am now enabled to give a more detailed description than the author has

done in his short diagnosis. A. candezei seems to be a most variable insect in regard

to colour, and it is very probable that other varieties exist; it greatly resembles A. hégei

in shape, but may be at once separated from that species by having two cost on the

elytra (instead of one) in both sexes. The thorax is of more transverse shape (agreeing

w this respect with A. melanocera) and is either fuscous, black, or fulvous, with a few

AULACOSCELIS. 8

fine punctures here and there. The elytra are opaque, finely punctured towards the

base only, the posterior portion being nearly impunctate; a longitudinal costa,

abbreviated at each end, is to be seen near the middle of the disc, and a more distinct

one extends from the shoulder to the suture; and there is also a trace of a third costa

between the other two at the base (all the coste are, however, nearly obsolete in one

male example) ; in the female insect these coste are much more strongly raised and

acute. The male has the first joint of the anterior and intermediate tarsi strongly

dilated. The antennz and the legs are entirely black in all the varieties. The elytra

have a peculiar whitish or violaceous bloom, as in A. héget. Chapuis gave Guatemala as

the locality for this species, but we have not received specimens of it from that country.

4. Aulacoscelis tibialis. (Tab. XXXV. fig. 2.)

Pale fulvous, the antenn (the first joint excepted), knees, tibiee, and tarsi black ; thorax impunctate ; elytra

opaque, finely punctured.

@. Elytra with two longitudinal coste, the inner one very short, the outer one strongly raised and extending

below the middle.

Length 5-5} lines.

Head narrowed in front, impunctate, shining, depressed between the eyes; palpi black; antenne half the

length of the body, black, the first joint fulvous, the joints somewhat triangularly shaped, the terminal

ones more elongate and slender; thorax scarcely broader than long, the sides straight behind and

slightly rounded in front, the posterior margin straight, the surface shining, with a round fovea at each

side and a less distinct depression at the middle of the base in the male, the base with a short.

longitudinal groove on each side, the disc impunctate; scutellum fulvous; elytra broadly ovate, opaque,

extremely finely and closely punctured, almost smooth in the male, distinctly costate in the female (the

outer costa commencing at the shoulder and extending to below the middle, the inner one only distinct

at the base); the underside and the femora fulvous, the knees, tibia, and tarsi black.

Hab. Guavemata, San Juan and Senahu in Vera Paz (Champion).

Almost of the same size and shape as the male of A. grandis, but with the head and

thorax more typical of the genus. The first joint of the intermediate tarsi in both sexes

is widened and flattened. The thorax in the female is devoid of the depressions peculiar

to the male, with the exception of the short longitudinal grooves at the base. Two

specimens only were obtained.

5. Aulacoscelis hogei. (Tab. XXXV. fig. 6.)

Reddish-fulvous; antenne (the first joint excepted) black; thorax not visibly punctured; elytra elongate,

very minutely punctate ; the knees, tibie, and tarsi black.

©. Elytra with a strongly raised costa at the sides.

Length 3-34 lines.

Head with a few minute punctures ; the palpi piceous or black ; antenne black or with the first joint fulvous ;

thorax subquadrate, the sides rounded at the middle, the base with a narrow transverse sulcation which

is bounded at the sides by a deep and distinct longitudinal groove, the surface not visibly punctured,

shining; elytra (¢ ) opaque and finely punctured, ( ) shining, more distinctly punctate, the sides with

a strongly raised longitudinal costa extending to the suture, and a longitudinal depression within the

shoulders.

Hab. Norta America, Vancouver Island (coll. Jacoby).—Mexico, Jalapa, Oaxaca,

Chilpancingo, Acapulco, Ventanas, Tapachula in Chiapas (Hoge), Tehuantepec (Sallé).

4 PHYTOPHAGA.—SUPPLEMENT.

At first sight this species seems to be but a variety of A. melanocera, to which indeed

it bears a great resemblance. A. héger differs, however, in the following manner: the

shape is much more elongate and narrow, the thorax is distinctly less transverse,

especially in the male, and the elytra are less shining and almost imperceptibly

punctured. The elytra in the female of A. melanocera are, moreover, devoid of the

lateral costa, and have only the shoulders acutely raised. Of both species I have the

two sexes before me and they can be at once distinguished. The male of A. melanocera

is shorter and of more widened shape than that of A. hége?, and has the elytra much

more shining and distinctly punctured and the thorax more transverse. In the male

of A. hégei a curious whitish bloom is to be seen on the elytra (when held sideways),

which is entirely absent in the allied form. About fifty specimens have been

received.

An example from Tehuantepec is figured.

6. Aulacoscelis variabilis. (Tab. XXXV. figg. 8, 9.)

Black ; thorax fulvous, closely punctured; elytra very finely punctured, black, the lateral margins narrowly

fulvous.

Var, Entirely black.

Length 3-4 lines.

Head piceous or obscure fulvous, distinctly and rather closely punctured at the sides; antenne black, the

joints short and subtriangular; thorax not or scarcely broader than long, the sides nearly straight,

slightly narrowed at the base, the latter with a distinct short longitudinal groove on each side, the

surface rather closely punctured, opaque; elytra very minutely punctured, of an opaque greenish-black

tint, the base and the margins generally furnished with very short silvery-greyish pubescence, the extreme

lateral margins and the epipleuree fulvous; legs and underside black.

Hab. Mxxico, Pachuca in Hidalgo (Hége), Real del Monte (Flohr).

A. variabilis may be readily known by the closely punctured head and thorax; its

general coloration, although variable, is constant in the black ground-colour of the

elytra. Herr Hoge obtained more than a hundred specimens at Pachuca, amongst

which those with a fulvous thorax predominate ; the elytra in the black specimens are

devoid of the fulvous margin and epipleure, and do not seem to differ much according

to sex—a slight depression within the shoulder in the female being the only indication.

The antenne in the male are, however, rather longer than in the female. We figure

both forms.

7. Aulacoscelis fulvipes.

Black or fuscous, pubescent; thorax finely punctured; elytra closely covered with greyish pubescence ; legs

fulvous.

Length 3 lines.

Entirely black or piceous, the head and thorax finely punctured, clothed with rather long greyish pubescence ;

the thoracic basilar groove somewhat indistinct ; elytra closely pubescent, the punctuation not visible -

legs entirely fulvous, the tarsi darker. . ,

Hab. Mexico, Guanajuato (Sailé).

AULACOSCELIS. 5

Closely allied to A. femorata, but differing in the thorax being more quadrate and

much more finely punctured, and also in the general dark, nearly black, coloration.

8. Aulacoscelis sanguinea. (Tab. XXXV. fig. 10.)

Broadly ovate, sanguineous, the antenne, knees, tibie, and tarsi black ; elytra opaque, entirely impunctate.

Length 4 lines.

Hab. Mexico, Chilpancingo in Guerrero (Hége).

Closely allied to A. hégei, but much shorter and more broadly ovate; the thorax

distinctly transverse, with the sides nearly straight; the elytra entirely opaque and

impunctate, without depression or coste in either sex; the antenne longer and nearly

half the length of the body; and the colour of the upper surface bright red, the head

and thorax only being shining.

9. Aulacoscelis elongata. (Tab. XXXV. fig. 5.)

Elongate, parallel, pale fulvous, the antenne (the first joint excepted), knees, tibie, and tarsi black; head and

thorax impunctate, shining ; elytra finely pubescent, opaque.

Length 6 lines.

6. Head longer than broad, not constricted behind, with only a few fine punctures near the eyes; the clypeus

separated from the face by a transverse groove, and at the sides by a short thick ridge in front of the

antenne; antenne half the length of the body, the first joint fulvous, the others black, the third joint

one half longer than the second but shorter than the fourth; thorax quadrate, not broader than long, the

sides evenly rounded at the middle, the basal and apical margins nearly straight, the surface slightly

convex, entirely impunctate, the base with a short and rather obsolete longitudinal groove on each side;

scutellum pubescent ; elytra but slightly narrowed towards the apex, covered with a long and silky

pubescence which hides any punctuation ; underside and the femora fulvous, the breast pubescent like

the elytra, the intermediate tibie curved; the first joint of the anterior tarsi dilated ; the last abdominal

segment deeply emarginate at the apex.

Hab. Mexico, Playa Vicente (Sallé).

This is a large and peculiar-looking Awlacoscelis and has much the appearance of a

species of the family Elateride. The typical characters of the genus are, however,

well expressed in the shape of the thorax and its short longitudinal groove, as well as

in the broad elytral epipleure, the armed tibie, and the simple claws. Only a single

male specimen is contained in the Sallé collection. A. elongata differs from all its

allies in the elongate and parallel shape and pubescent elytra.

10. Aulacoscelis femorata. (Tab. XXXV. figg. 3, 4.)

Elongate, parallel, fuscous or piceous; head and thorax fulvous, the latter distinctly punctured; elytra

testaceous, finely pubescent.

Var. Head partly, the elytra entirely, dark fuscous.

3. Head broad, all the femora strongly dilated.

9. Head narrower, the elytra with a longitudinal depression at the base, the femora less strongly developed.

Length 34-43 lines.

g. Head broad, not constricted behind the eyes, the latter small, the vertex and lower portion finely and

rather closely punctured and sparingly pubescent, the space between the antenne raised on each side into

6 PHYTOPHAGA,—SUPPLEMENT.

short but thick ridges which are separated by a transverse groove; mandibles long and slender; antenne

black, the first joint fulvous; thorax distinctly transverse, slightly narrowed near the base, the anterior

margin rather strongly produced in the middle, the anterior angles somewhat prominent, the surface

irregularly but distinctly punctured, with more or less distinct pubescence at the sides, the usual

longitudinal groove scarcely visible; scutellum transverse; elytra closely covered with long fulvous

pubescence, testaceous or nearly black, rather opaque; femora fulvous, strongly widened ; tarsi fuscous. -

Hab. Mexico, Capulalpam (Sal/é), Ventanas in Durango, Chilpancingo (Hoge).

The head and elytra in this insect vary in colour from testaceous to black, with

occasional intermediate shades. In the male the short depression which is to be seen

within the shoulders of the elytra in the female is absent, and the femora are much

more strongly developed. Occasionally the thorax is much more thickly pubescent

at the sides (in most specimens this is probably rubbed off) ; and in one female example

the elytra are densely covered with dark yellowish pubescence and the intrahumeral

depression is bounded at the sides by two short coste. The antenne in the male are

longer than in the female, but the joints are rather short and robust in both sexes

and shining.

11. Aulacoscelis grandis. (Tab. XXXV. fig. 1, ¢.)

Broadly ovate, subdepressed, black; thorax with three basal depressions; elytra orange-coloured, finely

pubescent.

Q. The intermediate joints of the antenne flattened and widened.

Length: ¢ 5, 2 7 lines.

Head elongate, constricted behind the eyes, the latter prominent, and with the space in front of their inner

margin longitudinally depressed, the centre raised, sparingly covered with whitish pubescence ; palpi

black, the terminal joint elongate, ovate, and thickened; antenne in the male half the length of the

body, all the joints, with the exception of the first and second, of nearly equal length, slightly flattened,

black; thorax scarcely broader than long, the sides with a narrow flattened margin, slightly narrowed in

front and nearly straight, the basal margin with a short longitudinal groove on each side, and a deeper

and larger one of subtriangular shape in the middle, the disc impunctate, with some more or less distinct

obsolete depressions and longitudinal stripes of white pubescence; scutellum broad, black; elytra

flattened, widened towards the middle, opaque, of a bright orange colour, covered with fine fulvous

pubescence; underside and legs black, the latter slender; claws simple.

Hab. Mexico, Ventanas in Durango (Hége).

Of this fine large species, a male and a female specimen were obtained by Herr

Hoge during his second Mexican expedition. Although the typical characters of

Aulacoscelis are here partly modified on account of the posteriorly constricted head

(which somewhat resembles that of a species of the family Carabide), and the sculpture

of the thorax differs from that of the other species, the main features of the genus are

present ; and taking into account the somewhat doubtful position and transitory form

of Aulacoscelis amongst the Phytophaga, it would not have been of any advantage to

establish another genus for the present insect.

The female of A. grandis is much larger than the male and has the intermediate

joints of the antenne more distinctly widened; it also has a deeper longitudinal

AULACOSCELIS.—HZMONIA. 7

depression at the sides of the thorax. The thorax is without a transverse basal groove

in either sex. The first abdominal segment is not three times longer than the second

(as Chapuis says of the type), but is scarcely twice as long, and the whole underside is

covered with thin yellowish pubescence.

Fam. DONACIIDE.

(To precede the Crioceride, p. 2.)

We have now to record from Central America both the known genera of this family.

DONACIA.

Donacia, Fabricius, Syst. Ent. p. 195 (1775).

This genus contains a large number of species, mostly inhabitants of the Palearctic

and Nearctic Regions, but also widely distributed in the warmer parts of the Old World.

South America has apparently no representative, and the southern limit of the genus

in the New World is in Cuba or Mexico. The single species here added to the Central-

American fauna is a well-known North-American form.

Donacia cincticornis, Newm. Ent. Mag. v. p. 391 (1838)’.

Var. Donacia rufipennis, Lac. Monogr. in Mém. Soc. Liége, iii. p. 110 (1845).

Hab. Nortu America! ?.—Mexico, Toxpam (Sal/é).

I am not able to find any difference of importance between the Mexican specimens

and one from North America contained in my own collection. The elytra are without

transverse rugosities, except at the sides, and their apices are truncate; they are

obscure brownish-eneous on the disc, this colour changing to a more metallic green at

. the sides. The thorax is slightly broader than long, without distinct angles, nearly

smooth and impunctate, and with a distinct central groove. The antenne are brownish,

each joint being dark at its apex, the fourth being nearly twice the length of the third.

The posterior femora extend slightly beyond the elytra and have a minute anterior and

a distinct posterior tooth.

HA:MONIA.

Hemonia, Latreille in Cuvier’s Régn. Anim. v. p. 186 (1829).

This genus contains about a dozen members, all from Europe or North America.

The different species are attached to water-plants and are more aquatic in their habits

than Donacia. One inhabits Mexico; it has lately been obtained by Herr Hoge in

great numbers, in the lagoons in the vicinity of the city of Mexico.

Ixtacalco (Flohr).

The insect described by me as H. flohri, upon comparison with a North-American

example of H. nigricornis, kindly communicated by Dr. Horn, proves to be conspecific

with that species, the black head and underside not being a constant character.

Amongst the 200 examples obtained by Herr Hoge there are several nearly black-

coloured specimens ; the legs, however, always remain fulvous.

LEMA (p. 2).

During the eight years this work has been in progress, a great many more species,

the majority of which are apparently undescribed, have been obtained from our region.

Many of the species are very closely allied and difficult to separate and require long

series from the same localities before their differences can be thoroughly understood ;

it is therefore quite possible that some of those described as new in this work, as well

as others included in Lacordaire’s monograph, will eventually be regarded as varieties

only, many having been founded on single specimens. In a monographic or faunistic.

work it is frequently necessary to describe from single examples, or three fourths of the

species would have to remain unnamed; for the monographer there is no choice but

to point out differences which he considers specific and which in so many closely allied

forms as in Lema must often of necessity be minute.

Lema bituberculata (p. 2).

To the Mexican locality given, add:—La Parada (Sallé), Amecameca in Morelos.

(Hoge).

I refer two specimens from the above localities to this species, with the description.

of which they agree in the main points. In both examples the two red frontal.

tubercles are present, although they are not equally well marked; the thorax in one

specimen is scarcely punctured and the elytral punctuation is also less deeply impressed,

but this may be a sexual difference; the antenne are rather short and robust (as given

by Clark); and the ninth row of elytral punctures is interrupted, though Clark Says.

nothing about this and places the species after L. nigrita. In this last-named insect,

however, as well as in all others belonging to the same group, the ninth row of punc-.

tures is entire, and L. bituberculata must therefore find its place in Lacordaire’s second

division.

LEMA. 9

8 (a). Lema quadraticollis.

Black; above metallic blue; antenne rather short; thorax subquadrate, punctured at the middle and ante-

riorly ; elytra slightly depressed below the base, deeply punctate-striate, the ninth stria not interrupted.

Var. Above obscure eneous.

Length 2 lines.

Head entirely impunctate, not constricted behind, the space round the eyes rugose, the latter but slightly

notched; antenne scarcely half the length of the body, black; thorax slightly broader than long, the

anterior angles somewhat tuberculiform, the basilar sulcation deep, oblique at the sides, and impressed

with some punctures, and from its middle a short longitudinal groove extends downwards to the base, the

surface with two central rows of punctures, the sides also sparingly punctured anteriorly ; elytra narrowly

parallel, with a very short depression near the suture below the base, the punctuation deep, but as usual

gradually diminishing towards the apex, the interstices flat.

_ Hab. Mexico, Jalapa, Cuernavaca (Hoge).

Amongst the small metallic blue species with uninterrupted ninth row of elytral

punctures the present insect may be known by the slightly indented eyes, the punc-

tured thorax, and the almost obsolete postbasal depression of the elytra (the latter

being very deeply depressed in L. angelica and most of the allied forms); the variety

only differs in colour. JL. fryi, Clark, belongs to the second division of Lacordaire’s

arrangement, and may be distinguished from the present species by the interrupted

ninth row v of elytral punctures.

8 (z). Lema fabricii.

Bluish-black; above metallic blue; head and thorax distinctly punctured; elytra obsoletely depressed below

the base, deeply punctate-striate, the ninth stria not interrupted.

Length 2 lines.

Hab. Mexico, Pinos Altos in Chihuahua (Buchan-Hepburn).

It will be sufficient to point out the differences which separate L. fabricit from the

other species of this section, although only a single specimen was obtained. The head

is very finely punctured and slightly wrinkled at the vertex, and the space surrounding

the eyes is raised and distinctly punctured ; the eyes are deeply notched; the antenne

are stout, short, and thickened at the terminal joints; the thorax, although of similar

shape and structure to that of Z. guadraticollis, is much more closely and distinctly

punctured than in that species, and has the two central rows of punctures more promi-

nent than the others; the elytra are still more deeply and very regularly punctured, but

their basal depression is not more strongly developed than in L. quadraticollis. The

principal characters by which L. fabricii may be known are the distinctly thickened

terminal joints of the antenne and the punctured head and thorax; the latter has

a deep transverse groove and in the centre a shorter longitudinal one extending to

the base.

3 (c). Lema propinqua.

Black or metallic blue; thorax but slightly constricted at the sides, the disc with two rows of punctures.

(sometimes obsolete); elytra flattened, scarcely depressed below the base, deeply punctate-striate, the

ninth stria entire ; femora short.

Length 13 line.

Hab. Panama, Volcan de Chiriqui 4000 to 5500 feet (Champion).

L. propingua, although not differing in any marked degree from several others of -

this section with uniformly coloured upper surface, may be known principally by its

small size and subdepressed elytra. The head is convex at the vertex and impunctate ;

it is not constricted behind the eyes and has no central groove; the lower part of the

face and the space surrounding the eyes, which latter are not very deeply notched, is

covered with yellowish pubescence; the antennz have the third joint one half longer

than the second, and scarcely extend to the middle of the body (in which they differ

from several similarly-coloured species described by Lacordaire). .The thorax is but

very moderately constricted at the sides and scarcely longer than broad; the basilar

groove is distinct, placed at some distance from the base, and slightly rugose within ;

the disc in some examples is impressed with two more or less distinct rows of punctures

which in others are often obsolete; some smaller punctures are also here and there

visible at the sides. The elytra are almost imperceptibly depressed below the base and

deeply and regularly punctured, the interstices becoming slightly costate towards the

apex where the punctuation is much finer. The posterior femora are very short.

Many specimens; the majority are entirely black, others are blue above.

5 (a). Lema chapuisi.

Lema chapuisi, de Borre, Ann. Soc. Ent. Belg. xxv. p. 75 (188])’.

Hab. Mexico}.

This seems to be one of the largest-sized species of Lema, the length, as given by the

author, being 9 millim. L. chapuisi is placed near L. chalybeipennis, Lac.

5 (ps). Lema amabilis.

Rufous, the antenne (the first two joints excepted), tibise, and tarsi black ; elytra metallic violaceous-blue, with

basal depression, the punctuation nearly obsolete below the middle.

Length 3 lines.

Head rufous, impunctate, the lateral grooves very deep; the eyes very deeply notched, surrounded by a

blackish space; antenne about half the length of the body, the first two joints rufous, the others black;

thorax not longer than broad, deeply constricted at the middle, the basal groove obsolete, the surface

impunctate, rufous, shining; scutellum black; elytra subdepressed, with a short impression below the

base, the latter and the impression deeply punctured, the punctuation thence to the apex very fine but a

little more distinct at the sides; underside and the femora rufous; tibie and tarsi black.

Hab. Mexico, Vera Cruz, Cordova (Sallé); Guatemana, Mirandilla (Champion).

This species although no doubt closely allied to L. chalybeipennis appears to be distinct,

on account of the rufous head and basal joints of the antenne, and the colour of the

femora; the elytra seem, however, to be similarly punctured. In the Guatemalan

LEMA. 11

example the head is entirely rufous (without the narrow black space surrounding the

eyes), the thorax is slightly more transverse, and the femora are tinged with fuscous at

the apex; other differences I am not able to find, and although it is possible that this

specimen may represent a closely allied but distinct species (on account of the more

transversely shaped thorax) I am not able to say so with certainty. The very fine

punctuation from the middle to the apex of the elytra will assist in the better recog-

nition of L. amabilis.

5 (c). Lema interstitialis.

Ferruginous, the antenns (the first joint excepted), knees, tibie, and tarsi black; thorax punctured on the

disc; elytra dark metallic blue, finely punctured, the interstices minutely punctate.

Var. The four anterior legs and the base and apex of the posterior femora black.

Length 23-33 lines.

Head impunctate, without central groove; the eyes deeply notched; antenne half the length of the body,

black, the first joint fulvous; thorax slightly longer than broad, the sides moderately constricted, the

surface with two rows of small punctures, not extending to the base, the basal sulcation shallow; scutellum

fulvous; elytra almost imperceptibly depressed below the base, the latter more deeply punctured than the

rest of the surface, the interstices somewhat transversely wrinkled and impressed with more or less distinct

fine punctures, the lateral margins strongly thickened and accompanied by a row of deep punctures ;

underside and the femora ferruginous, the knees, tibia, and tarsi black.

Hab. Muxico, Toxpam (Sailé).

L. interstitialis differs from L. amabdilis in having only the basal joint (instead of the

first two joints) of the antenne fulvous, in the punctured thorax, and in the elytra

being scarcely depressed below the base; and also in the finely punctured interstices

of the elytra. The allied Z. chalybeipennis, Lac., has the lower part of the head and

the antenne entirely black, and the basal depression of the elytra deep. Two speci-

mens, also obtained at Toxpam, are considerably smaller and differ from the type, as

well as from each other, in having the femora almost entirely, or partly at the apex,

and the sides of the breast, black; it is possible that they represent a closely allied but

distinct species. L. mannerheimi, Lac., from Cuba and San Domingo, differs from

L. interstitialis in the colour of the head, antenne, and legs.

Head black, impunctate; eyes deeply notched; antenne black, less than half the length of the body, the

terminal joints short and slightly flattened and scarcely longer than broad ; thorax not longer than broad,

deeply constricted at the sides, the middle of the disc with two rows of small punctures ; scutellum black ;

elytra with a slight depression below the base, the latter distinctly punctured, the lower portion finely

punctate-striate, the ninth stria entire, the surface of a dark metallic blue colour, with a narrow fulvous

transverse median band which is interrupted at the suture (in one specimen also at the sides); breast and

legs black; abdomen fulvous, the sides (sometimes the middle) of the segments marked with black.

The Mazatlan examples differ from the type in the abdomen being fulvous and

spotted with black (instead of wholly black), but apparently in no other way.

7 (a). Lema fulvo-fasciata. (Tab. XXXV. fig. 19.)

Reddish-fulvous, the antenne, tibie, and tarsi black; elytra distinctly punctate-striate, purplish-black, with a

broad transverse fulvous band across the middle.

Var. Elytra with the posterior purplish portion in the shape of an ovate spot, the extreme apex black; the

knees black. ;

Length 22-3 lines.

Head impunctate, the space round the eyes strongly raised, but not punctured (in one specimen black);

antennee rather short and robust, not extending much beyond the base of the elytra, black, the basal joint

sometimes fulvous; thorax not longer than broad, moderately constricted at the sides, the basal sulcation

not very strongly marked, the surface (with the exception of a few minute punctures on the middle of the

disc) impunctate; scutellum fulvous or black; elytra with a shallow depression below the base, very

regularly and rather closely punctate-striate, the punctuation as usual more strongly impressed anteriorly

than posteriorly, the interstices slightly convex towards the apex, the broad fulvous band dividing the

purplish-black portion convex at its middle and with its margins rather uneven; underside and the

femora fulvous (in one specimen the latter are black at the base and apex); tibie and tarsi black.

Hab. Mexico, Acapulco in Guerrero (Hége), N. Yucatan (Gawmer).

Two examples of the type, and one of the variety.

L. fulvo-fasciata differs from any other species of our region (L. cingulata excepted)

in the elytra having a broad fulvous median band, the rest of the surface being

purplish-black; in one specimen there is an additional small fulvous spot placed at

the margin near the extreme apex of each elytron. The last-named example has the

head and femora entirely fulvous; the other has several black markings on the head

and legs, as pointed out in the description. The colour of the head and underside

and other details separate L. fulvo-fasciata from L. cingulata. The variety is from

Yucatan.

Lema bitzniata (p. 4).

To the locality given, add :—Mzexico, Toxpam, Cordova (Sallé); GuaTemaLa, Panima

in Vera Paz (Champion).

The single specimen from Guatemala only differs from the Mexican examples in

having the antenne fuscous instead of fulvous.

11 (a). Lema incerta.

Black, the two basal joints of the antenns, the head, and thorax red; elytra violaceous-blue, the lateral

margins, a transverse band at the middle, and another at the apex, flavous; femora flavous, the tibie

black.

Length 24 lines.

Hab. Mexico, Tuxtla (Sallé).

It will only be necessary to point out the differences between L. incerta and

L. biteniata. The antenne in Z. incerta are shorter, and, with the exception of the

two basal joints, nearly black (in L. diteniata they are fulvous); and the thorax is

narrower and more constricted in the middle, and the disc is impressed with a single

row of rather distinct punctures. The punctuation and the pattern and colour of the

elytra are absolutely the same as in L. ditewniata, but the tibie and tarsi are black.

Although there is only a single example before me, there can be no doubt of its being

a good species.

11 (s). Lema dimidiaticornis. (Tab. XXXV. fig. 13.)

Lema dimidiaticornis, de Borre, Ann. Soc. Ent. Belg. xxv. p. 78 (1881)*.

Hab. Mzxico1, Toxpam (Sallé), Cerro de Plumas (Hége); Panama, Bugaba (Cham-

pion).

This species seems subject to a good deal of variation in regard to colour, that is, if

all the specimens before me are to be regarded as one and the same species. Only a

single example agrees perfectly with the author’s description; the others differ in the

antenne being fulvous, with the last joint black or nearly so (in the description the

antennge are stated to be fulvous with the last four joints fuscous); the fulvous spot at

the base of the elytra is as often wanting as present, and the central fulvous band is in

most specimens narrow and of equal width (instead of being broader at the lateral

margin). L. dimidiaticornis may be separated from L. equestris by the colour of the

legs and underside, and from L. elegantula and L. biteniata by the elytra not having

a narrow fulvous or flavous lateral margin. The author states that the punctuation of

the elytra is rather feeble; in the specimens before me the punctuation is strong and

deep at the base, but very fine below the middle. In the examples from Bugaba the

elytra have their central fulvous band narrower and very regular, extending across the

suture, and the apical spot in the shape of a narrow oblique stripe (instead of a spot as

14 PHYTOPHAGA.—SUPPLEMENT.

in the typical form) which sometimes (in two specimens) is entirely absent; the colour

of the underside and legs is, however, constant. An example from Toxpam is figured.

12 (a). Lema distincta.

Pale fulvous, the head, the intermediate joints of the antenne, the basal margin of the thorax, the breast, and

the tibie and tarsi black; elytra black, a small spot at the base, a narrow transverse band at the middle,

and the apices fulvous.

Length 3 lines. .

Head impunctate; eyes deeply notched; antennze slender, half the length of the body, the basal joint black,

the second and third joints obscure piceous, the four following joints black, the three apical ones flavous ;

thorax scarcely longer than broad, obscure testaceous, the sides very moderately constricted, the basal

sulcation nearly obsolete, the disc with four obscure small piceous spots, placed transversely, the basal

margin black; elytra with an obsolete depression below the base, rather strongly punctured on the

anterior portion, the punctuation almost obsolete from the middle downwards, the interstices flat, with

a broad black band, including a small fulvous spot, occupying their anterior half, and a similar band (the

lower edge of which is deeply emarginate near the suture, and also extends a little distance down the

latter) below the middle; femora above and the tibie and tarsi black.

Hab. Guatemata, Panima in Vera Paz (Champion).

The single specimen obtained, although closely allied to L. flavo-fasciata, Clark,

differs sufficiently to regard it as distinct. The colour of the antenne and legs and the

nearly impunctate posterior portion of the elytra will help to distinguish L. distincta.

The elytral punctuation is only deep near the suture, and anteriorly on all other parts

it is almost imperceptible; the posterior black band extends to the extreme lateral

margin, but the anterior one is interrupted by the latter.

12 (s). Lema sexsignata.

Ferruginous, the apical four joints of the antennx fuscous; elytra dark violaceous-blue, the extreme lateral

margin, a spot at the base, a transverse band at the middle, and the apex, bright yellow ; abdomen flavous.

Var. Tibie black.

Length 24-3 lines.

Hab. Mexico, Tuxtla (Sallé).

L. sexsignata is closely allied to L. dimidiaticornis and several other species belonging

to the same group (e. g. L. equestris and L. troberti), but apparently distinct from all of

them; it differs from the first named in the narrow yellow lateral margin of the elytra

and in the flavous (not black) abdomen. It may be separated from L. biteniata by

the colour of the underside, and from L. biornata by the colour of the head. The

elytra have a short postbasal depression within which the punctuation is, as usual,

deep, though diminishing gradually towards the apex. The variety only differs in the

colour of the tibiz.

12 (c). Lema apicicornis. (Tab. XXXV. fig. 14.)

Black, the three apical joints of the antennx, the thorax, and the abdomen flavous; elytra metallic violaceous-

blue, a transverse band at the middle, and an oval spot at the apex, flavous.

Length 3-4 lines.

LEMA. | 15

Head impunctate, black, with the usual grooves; antenne black, the three (sometimes four) apical joints

flavous, the fourth joint twice as long as the third; thorax about as long as broad, somewhat deeply

constricted at the middle, the transverse basal sulcation not strongly marked, the disc with two rows of

minute punctures arranged longitudinally, and the space between sometimes with a longitudinal groove ;

elytra with a distinct transverse depression below the base, deeply and regularly punctate-striate anteriorly,

the punctuation becoming very much finer below the middle, and here replaced by lines, the interspaces

between which are raised, each with a broad transverse flavous spot or band at the middle (not extending

to the suture or lateral margin), and a rounded spot near the apex, the latter surrounded posteriorly by a

narrow margin of the ground-colour; breast and legs black; abdomen flavous.

Hab. Panama, Bugaba, David (Champion).

Numerous examples. In a single specimen the anterior femora are flavous, and the

posterior femora have a flavous spot at the middle.

12 (vp). Lema sexplagiata, (Tab. XXXV. fig. 15.)

Head, the eight lower joints of the antenne, and the breast, black, the thorax, the femora more or less, and the

abdomen, flavous; elytra black, a spot at the base, a larger one at the middle, and the apices, flavous.

Var. Legs entirely black.

Length 23-3 lines. .

Head deeply constricted behind, almost impunctate, the space surrounding the eyes alone finely punctured ;

antenne black, the three (sometimes four) apical joints flavous, long and slender, the third joint twice as

long as the second, but shorter than the fourth; thorax scarcely longer than broad, deeply constricted at

the sides, the basilar sulcation almost obsolete, the disc impunctate, flavous, the basal margin (in some

specimens) black; elytra without trace of a basal depression, finely punctate-striate, the punctuation

scarcely stronger anteriorly than posteriorly, the interstices towards the apex more or less distinctly

costate, black, with a round spot immediately below the base, a larger and more transversely shaped one

_at the middle, and the apices broadly, flavous; legs variable in colour, generally flavous, the base of the

femora and their upper portion as well as the tibie and tarsi, black; abdomen flavous.

Hab. Panama, Bugaba (Champion).

Many specimens. In general coloration and in the pattern of the elytra L. sexplagiata

exactly resembles L. apicicornis, a species obtained at the same locality; but differs in

its generally smaller size, and in the elytra being without a basal depression, and having

an extra spot placed near the base. The elytra in L. sexplagiata are flavous at the

apex as well as at their margins (in L. apicicornis a narrow black margin surrounds

the flavous portion), and their ground-colour is, moreover, entirely black instead of being

of a distinct blue shade at all the darker portions as in L. apicicornis. In some speci-

mens the black bands separating the elytral spots do not extend to the lateral margins,

these latter as well as the epipleure remaining flavous; in all the lower margin of the

posterior black band is deeply emarginate.

Lema transverso-fasciata (p. 4).

To the localities given, add:—Panama, Bugaba (Champion).

Panama specimens differ from those from Costa Rica in having a slightly narrower

blue band to the elytra, and in the interstices between the punctures being somewhat

more convex. . transverso-fasciata in regard to the elytral pattern is no doubt as

variable as many of its allies, thus necessitating the examination of long series of

specimens to distinguish between varieties and species.

15 (a). Lema obliterata.

Rufous, the antenne: and legs black ; thorax deeply constricted at the sides, impunctate; elytra convex, without

basal depression, metallic blue, the punctures obliterated below the middle, the extremé apex obscure

fulvous.

Length 2 lines.

Head constricted, impunctate, rufous, the eyes somewhat deeply notched, the lateral grooves deep; antennz

entirely black, half the length of the body, the third joint slightly shorter than the fourth; thorax about

as broad as long, deeply constricted at the middle, the anterior angles rounded, the surface impunctate,

the basal sulcation not deep but distinct; scutellum piceous; elytra convex, subcylindrical, with an

indication of a slight impression below the middle near the suture, the intrahumeral groove very short,

the punctuation distinct at the base, but almost entirely obsolete from the middle, where it is replaced

by slightly impressed stris, the apical margin fulvous, the ninth row of punctures entire; legs entirely

black; underside rufous.

Hab. Panama, David in Chiriqui (Champion).

A single specimen. This species is distinguished from its allies by the elytra being

almost without depression, and with the punctuation at the middle nearly obsolete, in

connection with its apical fulvous margin and the black legs and antenne.

Lema salvini (p. 6).

Also obtained by Mr. Champion at the locality given ; this insect may be readily

25 (a). Lema bistriata.

Fulvous, the antenne (the basal joint excepted) and the tibie and tarsi black; elytra closely and deeply

punctate-striate, the interstices longitudinally costate, the suture very narrowly, and a sublateral stripe,

metallic bluish-black.

Length 23-22 lines.

Head constricted behind the eyes, very finely transversely strigose on the vertex, the space surrounding the

eyes swollen, the latter somewhat deeply notched; the labrum and mandibles fulvous; antenne two

thirds the length of the body, slender, black, the first joint fulvous; thorax scarcely broader than long,

but very moderately constricted at the sides, the basal sulcation not very strongly marked, the surface

impressed with a few very minute punctures on the middle (only to be seen under a very strong lens);

scutellum fulvous; elytra rather flattened, without any trace of a basal depression, closely and deeply

punctured, the interstices distinctly longitudinally costate, the second and the two outer coste much

broader than the others, the intermediate coste confluent behind at some distance from the apex, with

the suture narrowly, and a narrow stripe (placed just within and accompanying the strongly thickened

lateral margin), commencing at the shoulder (where it is much h wider) and extending nearly to the apex,

metallic blue, the ninth row of punctures entire.

the eighteenth group of Lacordaire’s monograph, by the costate interstices, the obsolete

basal depression, and the narrow sutural and sublateral stripes of the elytra.

In one specimen the upper edge of the femora is more or less stained with black.

25 (z). Lema nigro-lineata. (Tab. XXXV. fig. 25.)

Fulvous, the head, the seven lower joints of the antenne, the sides of the breast, and the tibia and tarsi black ;

thorax impunctate ; elytra closely punctate-striate, flavous, narrowly margined with black, the black

margin interrupted before the apex.

Length 23 lines.

Head black, impunctate; antennz about half the length of the body, black, the apical four joints fulvous, the

third joint twice as long as the second; thorax slightly longer than broad, fulvous, moderately constricted

at the sides, the basilar groove rather shallow but well marked, the surface entirely impunctate, very

shining; elytra without basal depression, deeply and closely punctured, the interstices costate near the

apex, the sutaral, basal, and lateral margins narrowly black (this colour extending to about four fifths of

the length of the elytra, and forming a broader spot at the shoulders) ; the epipleurs, underside (with the

exception of a narrow black band at the sides of the breast), and femora flavous, the tibie black, the

tarsi piceous.

Hab. Mexico, Toxpam (Sallé).

A single specimen. J. nigro-lineata will enter the nineteenth group of Lacordaire’s

arrangement, on account of the fulvous terminal joints of the antenne. ‘The details of

the elytral pattern, and the colour of the legs &c., separate the species from any of its

allies of somewhat similar markings, more particularly from L. abrupta, Lac.

25 (c). Lema variabilis.

Fulvous, the head, the intermediate joints of the antenne, the breast, and the tibie and tarsi black; thorax

fulvous ; elytra testaceous, a sublateral longitudinal stripe, a spot below the base, a transverse band beyond

the middle, and the suture, black.

Var, The black markings more or less confluent.

Length 4 lines.

Head black, impunctate, the base more or less fulvous ; antenne less than half the length of the body, black,

the apical three joints obscure fulvous; thorax subquadrate, the basilar sulcation not very deep, the

surface entirely impunctate, fulvous; scutellum black; elytra slightly depressed below the base, finely

punctate-striate, the interstices slightly convex towards the apex, the suture, a narrow sublateral stripe

extending to the middle, an elongate spot below the base, and a subangulate transverse band of variable

size below the middle, black; the breast black, the abdomen and the femora fulvous.

Hab. GuatemMata, Las Mercedes, Cerro Zunil (Champion).

L. variabilis seems somewhat allied to L. suffriani and L. semisepta, but differs in the

elytra having a transverse postmedian band. In the variety the basal spot is confluent

with the black lateral stripe, and the transverse band is slightly curved in shape and

extends across the suture; in the typical forms this band is abbreviated on each side,

and angulate at its outer ends.

25 (p). Lema maculigera. (Tab. XXXV. fig. 17.)

Head and breast black, the antenne and the thorax fulvous, the latter punctured on the disc; elytra testaceous,

LEMA. 19

deeply punctate-striate, the interstices costate towards the apex, a short sutural stripe at the base, a semi-

lunate band at the shoulders, and another below the middle, black or bluish-black ; legs fulvous.

Length 33-4 lines.

Hab. Mexico, Pinos Altos in Chihuahua (Buchan-Hepburn), Jalapa (Hége).

Two specimens. The pattern of the elytra in Z. maculigera resembles that of

L. suffriani and L. hamata, from both of which the deep elytral punctuation and the

more strongly costate interstices separate it. The thorax, instead of being impunctate,

has some punctures at the sides of the anterior margin, and others placed longitudinally

on the middle of the disc. The elytra are almost imperceptibly raised at (or depressed

below) the base, but the markings vary in shape—in the specimen from Jalapa the

humeral stripe is curved towards the suture at its lower end and is of equal width, in

the other this stripe is narrower, more strongly curved, and extends nearer to the

suture; in the latter the posterior semilunate band is interrupted at its middle, while

the corresponding mark in the Jalapa specimen is shorter, less curved, and thicker. I

cannot find any other differences to separate the two forms, except the more strongly

raised elytral cost, which I think indicate sexual difference only, in the Jalapa insect.

The Jalapa specimen is figured.

27 (a). Lema sexlineata. (Tab. XXXV. fig. 22.)

Testaceous, the head, the basal joint of the antenne, and the breast black; thorax impunctate; elytra finely

punctate-striate, the suture anteriorly and posteriorly, a short stripe on each shoulder, and another near

the apex at the sides, black.

Length 3 lines.

Hab. Guatemana, Cerro Zunil (Champion).

The single specimen before me differs again from L. suffriani and other allied forms

in the elytral pattern and in the entirely testaceous legs. The antenne are testaceous,

but with the first two joints black, and of half the length of the body; the space

surrounding the eyes is rugose. The thorax is subquadrate, impunctate, and of pale

testaceous colour like the rest of the upper surface. The elytra have a shallow

depression below the base, and are finely punctate-striate beyond the middle; the

three anterior stripes are of equal length, the humeral stripe being rather broader

than the sutural one; the posterior lateral stripe is placed in a line with the one on the

shoulder and close to the lateral margin, but is only half the size of the posterior sutural

stripe, the latter does not quite extend to the apex.

Two specimens obtained by Mr. Champion agree well with the description of

20 PHYTOPHAGA.—SUPPLEMENT.

L. hamata. The Panama specimens have the elytral markings blue instead of black,

as stated by Lacordaire.

Lema biannularis (p. 7).

To the locality given, add :—Muxico, Cordova (Sallé), Jalapa, Tapachula in Chiapas

(Hoge); Costa Rica (Van Patten), Cache (Rogers); Panama, Volcan de Chiriqui

(Champion).

The type of this species is unfortunately not contained in the British Museum, and

is probably lost. The numerous specimens received from the above localities nearly

agree with Clark’s description, but show so much variation amongst themselves that it

is quite impossible to say if all (or any) of them represent the true L. biannularis; in

several the elytral rings are blue (not black, as stated in the description); and the

posterior semilunate mark is scarcely of the same shape in any two specimens, it being

more or less curved or straighter, and longer or shorter, in different individuals. The

Chiriqui examples are much smaller, and have the elytral markings equally variable in

shape. Clark gives Guatemala as the locality, whence, in spite of the very large

amount of material at my disposal, I have not seen a specimen. If I were to treat

those before me as distinct, I should have to describe half a dozen extremely closely

allied and doubtful species. For the present I prefer to regard them as belonging to

one variable and widely distributed species.

Lema bicincta (p. 7).

To the locality Mexico, add :—Jalapa, Colima city (Hége), Cuernavaca, Juquila (Sallé).

To judge from Lacordaire’s description it is somewhat doubtful whether the specimens

obtained from the above localities really represent this species or L. lucublanda, Lac. ;

I think that I rightly refer them to ZL. bicincta. In all our examples (with one

exception) the first joint of the antenne is black (of which Lacordaire says nothing);

the anterior blue band of the elytra is rather deeply dentate at its posterior margin,

and the posterior band is only half the width of the anterior one, and does not extend

(as it is stated to do in L. bicincta) to the lateral margin. I am, however, unable to

find any other difference, and it is quite possible that the bands of the elytra are subject

to variation.

80 (a). Lema chiriquensis. (Tab. XXXV. fig. 18.)

Testaceous, the basal joint of the antenne, the head, and the breast black ; elytra strongly punctate-striate

anteriorly, a broad transverse band at the base and another below the middle violaceous-blue

Length 23-3 lines. -

Hab. Panama, Volcan de Chiriqui (Champion), Colon (Boucard).

LL. chiriquensis averages rather smaller in size than Z. bicincta, and differs in having

LEMA. 21

an elytral depression near the suture below the base (this being absent in L. bicincta) ;

the punctures within this depression are distinctly deeper and larger than the others,

the latter gradually diminishing towards the apex, where the interstices are more or

less convex. The posterior band of the elytra is as broad as the anterior one, and

nearly straight (in ZL. dicincta it is strongly curved), and does not extend to the lateral

margin. The ground-colour of the thorax and elytra of L. chiriquensis is generally paler

than in L. bicincta; the antenne extend to about half the length of the elytra; the

thorax is but moderately constricted at the sides, the transverse basal groove is also not

very deep, and a few fine punctures may be seen (under a strong lens) on the middle

of the disc; the rest is as in LZ. bicincta. I have examined eighteen specimens, all

agreeing in the above particulars.

30 (s). Lema forreri. (Tab. XXXV. fig. 16.)

Fulvous, the head, the basal joints of the antenne, and the breast black; elytra very deeply punctate-striate,

a transverse band at the base, and another below the middle, blue; posterior femora with a black spot.

Length 24-3 lines.

Head impunctate, black, the grooves round the eyes very deep; antenne short and robust, not extending beyond

the base of the elytra, fulvous, the basal joint black, the second and third joints very short and nearly

equal; thorax reddish-fulvous, but moderately constricted at the middle, the basilar sulcation not very

deep, the middle of the disc with several rows of minute punctures which disappear towards the base ;

scutellum black; elytra with a short depression below the base, very deeply, strongly, and closely punc-

tured on the anterior portion, more finely so behind, the interstices convex towards the apex, the anterior

blue band sinuate at its posterior margin near the suture, and extending to the extreme lateral margin,

the posterior band of equal width, but not reaching to the margin; the underside and legs fulvous, the

breast and a spot at the middle of the posterior femora black.

Hab. Mexico, Presidio (forrer).

The elytral pattern of this species is again similar to that of L. dicincta and several

others; the deep punctuation of the elytra, however, in connection with the short and

robust antenne, separate L. forrert from any of its allies. The spot on the posterior

femora is present in three out of the four specimens before me.

30 (c). Lema cyaneo-fasciata.

Head and thorax rufous, the antenne and legs fulvous; elytra strongly punctate-striate, flavous, a transverse

band at the base, and another below the middle, blue; breast black; abdomen flavous.

Length 24-3 lines.

Hab. Mexico, Oaxaca (Salié).

Although at first sight the present insect seems identical with LZ. bicincta, L. forreri,

and other similarly-marked species, the colour of the head and of the antenne does not

allow of its identification with either. The two specimens before me, although obtained

at the same locality, differ somewhat from each other—in one the antenne are compa-

ratively short and robust, and entirely fulvous, and the elytra are very strongly

punctured anteriorly, but the punctuation gradually diminishes in depth towards the

22 PHYTOPHAGA.—SUPPLEMENT.

apex, and the blue bands extend to the extreme lateral margin; in the other (which

has unfortunately lost its antenne) the punctuation of the elytra is much finer

posteriorly, and the second band is widened at the lateral margin, and extends down-

wards along the suture to the apex. In both examples the thorax is subquadrate, and

only moderately constricted at the sides, and impunctate; the elytra are scarcely

depressed below the base, and the posterior margin of the anterior blue band is rather

deeply indented at its middle, and the second band is of the same size, but more regular

and slightly curved; and the legs are entirely fulvous or flavous, but with the claws

nearly black.

Lema championi (p. 7).

To the locality given, add :—GuateMaLa, San Isidro, Cerro Zunil (Champion) ; Nica-

racua, Chontales (Janson); Panama, Volcan de Chiriqui (Champion).

A few specimens have been obtained at the above localities which differ from the

others in having a small fulvous spot placed within the blue basal band of the elytra.

In L. championi the entire apical portion, as well as the central transverse band, of the

elytra is fulvous or flavous.

82 (a). Lema strigipennis.

Fulvous, the head, the sides of the breast, and a spot on the four hinder femora black ; thorax longitudinally

punctured ; elytra with a deep depression below the base, strongly punctate-striate, the interstices finely

reticulate, fulvous, a transverse band at the base, and another near the apex, metallic greenish.

Length 24 lines.

Head black, impunctate, the neck fulvous, the lateral grooves very deep; antenne robust, scarcely half the

length of the body, fulvous, the basal joint piceous ; thorax not longer than broad, strongly constricted at

the sides, the basal sulcation moderately distinct, the surface with three longitudinal rows of punctures on

the middle of the disc and some scattered punctures near the anterior margin at the sides; scutellum

black ; elytra with a deep depression below the base, strongly and closely punctured anteriorly, less deeply

so behind, the interstices costate towards the apex, finely reticulate, and punctured; below fulvous, the

sides of the breast, a spot on the intermediate, and another on the outer side of the posterior, femora,

black, the tibiee and tarsi fulvous.

Hab. Mexico, Ventanas (Forrer).

A single specimen. J. strigipennis seems to be nearest allied to Z. lucublanda, from

which it differs in the shorter antenne, the punctured thorax, the finely reticulate

elytral interstices, and the colour of the femora; it agrees with Z. lucublanda in the

elytra having the ninth row of punctures uninterrupted.

Lema bisbivittata (p. 8).

To the locality given, add :—Guatema.a, Cerro Zunil (Champion).

I have already drawn attention to the mistake made by Clark in comparing this

species with Z. signaticollis. The author, moreover, gives the thorax as “ punctatus,”

LEMA. . 93

’

and states afterwards that ‘no traces of punctures are visible:” an examination of the

type proves the thorax to be impunctate. Clark has further omitted to state that

the knees are black in the example he described. One of the specimens obtained by

Mr. Champion in Guatemala agrees very nearly with the type, but the other differs in

having the abdomen and legs entirely fulvous; the latter doubtless represents a variety

of the same species.

34 (a). Lema clarki, (Tab. XXXV. fig. 21.)

Black; antenne pale fulvous; thorax reddish-fulvous, distinctly punctured on the disc and anteriorly ; elytra

fuscous, tinged with violaceous, a narrow subsutural and lateral longitudinal stripe, joined at the apex,

flavous ; legs fulvous, the knees, the apices of the tibiee, and the tarsi, black.

Length 3-4 lines.

Hab. Mexico, Ventanas (Forrer), Juquila, La Parada (Sai/é).

Five specimens. ‘The distinctly punctured thorax separates this species from JZ. bisbi-

vittata, which in other respects it closely resembles. The base of the head is in several

examples rufous (as is also the case in Clark’s species); the thorax is rather broad and

flattened, and has two rows of punctures on the middle of the disc and some other

punctures near the anterior angles. The elytra are longitudinally costate, deeply

punctured between the raised spaces, and here and there with traces of minute

punctures on the coste themselves; the subsutural flavous band occupies the space

between the second and fourth row of punctures, but the lateral stripe is confined to

the raised margin only.

34 (p). Lema bella. (Tab, XXXV. fig. 23.)

Fulvous, the head, antennew (the two basal joints excepted), the breast, knees, and the apices of the tibia

black ; thorax finely punctured on the disc, fulvous; elytra deeply punctate-striate, the suture, and a broad

longitudinal band (not extending to the apex) on the disc, metallic blue.

Length 4 lines.

Head impunctate, black; the eyes not very deeply notched; antenne short, extending very little beyond the

base of the elytra, black, the two basal joints fulvous; thorax broader than long, fulvous, the disc rather

flat, and with two rows of fine punctures down the centre, the anterior angles also punctured, the basal

sulcation distinct at the middle only and there forming a kind of fovea; scutellum black, depressed ;

elytra with the first four rows of punctures placed somewhat in pairs, the other rows very deeply impressed

and with their interstices costate, the sutural blue stripe gradually narrowing and abbreviated at some

distance from the apex and extending laterally to the second row of punctures, the extreme sutural

margin piceous at the apex, the discoidal band widened posteriorly, not extending to the apex, and

occupying the space between the fourth row of punctures and the lateral margin, the latter narrowly

flavous; abdomen and femora fulvous, the breast, knees, tibiee (their base excepted), and tarsi black.

Hab. Mexico, La Parada (Sal/é).

Of this handsome species only a single specimen is contained in the Sallé collection.

The metallic blue colour of the elytral bands and the colour of the antenne and

abdomen sufficiently separate Z. bella from L. clarki and L. signaticornis.

24 PHYTOPHAGA.—SUPPLEMENT.

Lema varipes (p. 8). |

To the locality given, add:—Mexico, Vera Cruz (Sallé), Jalapa (Hoge) ; Costa Rica

(Van Patten).

Lema nupta (p. 8).

To the localities given, add :—Mexico, Tuxtla, Vera Cruz, Playa Vicente (Sal/é),

N. Yucatan (Gawmer); Guaremata, San Isidro (Champion).

It seems rather doubtful to me whether Z. nupta and L. varipes are really distinct ;

apparently they only differ in the colour of the antenne, these organs having the first

six joints fulvous (instead of the first four) in Z. nupta. I now possess specimens in

which the five basal joints of the antenne are fulvous; these agree in other respects

with both Z. nupta and L. varipes, thus showing that this colouring is subject to

variation. The elytral spots are equally variable, some specimens being devoid of

several, while others have them largely developed; intermediate degrees are also not

wanting. J. varipes is stated by Lacordaire to be from Mexico; in speaking of

L. nupta he says, however, that this species, as well as the preceding (ZL. varipes), is

found in Colombia; several specimens of Z. nupta having now been received from

Mexico proves this locality to be the correct one.

86 (a). Lema stigmula.

Pale fulvous; antenna (the first joint excepted), a spot on the vertex, another on the anterior part of the

thorax, three spots on each elytron, placed triangularly, and the tibiae and tarsi, black.

Length 33 lines.

Head impunctate, with a small black spot on the middle of the vertex; eyes nearly entire; palpi robust;

antenne short and stout, gradually widened and flattened towards the terminal joints, black, the basal

joint fulvous; thorax scarcely broader than long, moderately constricted at the sides, with a deep fovea

near the base, the basilar sulcation nearly obsolete, the surface with two rows of punctures on the middle

of the disc and a few fine punctures near the anterior margin, the latter with a small black spot in the

middle; scutellum small, black ; elytra of a paler colour than the thorax, very convex, robust, and without

basal depression, distinctly punctate-striate, the interstices very minutely punctured, here and there some-

what wrinkled, and towards the apex becoming subcostate, the three spots placed thus—one at the

shoulders, one near the suture before the middle, and one a little lower down near the lateral margin ;

underside fulvous, except a small black spot at the sides of the breast below the middle; tibie and

tarsi black.

Hab. Costa Rica, Cache (Rogers).

A single specimen. JL. stigmula is distinguished from L. varipes and L. nupta by

the broadly widened joints of the antenne, and the position of the spots and the fine

punctuation of the interstices of the elytra.

36 (p). Lema regularis,

Testaceous ; antenne black, the two basal joints fulvous ; head with one spot, and the thorax with two lateral

spots and a central line, black; elytra closely punctate-striate, a small spot at the shoulder, another

LEMA. 25

across the middle, and the sutural and lateral margins, black; tibie and tarsi and several spots on the

breast, black.

Length 32 lines.

Of robust and convex appearance; the head impunctate, with the usual deep grooves, the vertex with a large

triangular black spot ; antenne short and robust, gradually widened towards the apical joints, the latter

not longer than broad, the first two joints fulvous, the rest black; thorax subquadrate, the anterior margin

straight, the sides moderately constricted, the basal groove almost obsolete but impressed with a small

fovea at the middle, the surface with some very minute punctures on the middle and anteriorly at the

sides, the latter with two black spots placed one below the other, the disc with a narrow straight black

central stripe which extends from the anterior margin nearly to the base; scutellum black; elytra convex,

broad, with a scarcely visible depression below the base, strongly and closely punctate-striate anteriorly,

the punctuation gradually diminishing in depth posteriorly, and-with some very small punctures scattered

between the larger ones, the interstices costate towards the apex; each elytron with a transverse black

spot on the middle and an obliquely shaped one at the shoulder, the sutural and the lateral margins, from

a little distance below the base to the apex, also deep black; the epipleure, underside, and femora pale

fulvous, a spot on each coxa, another at the sides near the anterior coxe, two spots (one anterior and the

other posterior) on the parapleure of the breast, and the’knees, tibia, and tarsi, black.

Hab. Panama, Volcan de Chiriqui (Champion).

Of this well-marked species only one specimen has been received. On account of its

general robust appearance and the structure of the antenne L. regularis should be

placed near L. nupta and L. varipes, from which the black margins and the position of

the spots of the elytra will readily distinguish it.

36 (c). Lema brunnea.

Robust, convex, pale brownish, joints 6-10 of the antennw, a central streak and two small spots on the sides

of the thorax, the apices of the tibie, and the tarsi, black; elytra strongly punctured anteriorly and

finely so posteriorly.

Length 34 lines.

Head impunctate, entirely fulvous, the neck scarcely constricted, the usual grooves deep; antenne short and

robust, the terminal joints widened and flattened, the five basal joints and also the apical one fulvous,

the others black ; thorax slightly longer than broad, the sides somewhat deeply constricted, the posterior

margin strongly rounded, the basal sulcation entirely obsolete, the surface smooth, shining, very minutely

punctured on the disc, fulvous, with a narrow black longitudinal stripe (interrupted anteriorly and not

extending to the base), and two small spots placed one below the other at the sides; elytra convex, without

basal depression, strongly punctured anteriorly and very finely so from the middle to the apex; underside

and legs fulvous, the extreme apices of the tibiz and the tarsi black.

Hab. Mexico, Tehuantepec (Sa//é).

A single specimen, differing from L. nupta and L. varipes in the colour of the

antenne, absence of elytral spots, and unicolorous underside; it is, however, quite

possible that L. brunnea is but a variety of L. nupta.

36 (p). Lema immaculipennis.

Obscure pale fulvous, the antenne (the basal joint excepted), the knees, the apices of the tibia, the tarsi, and

some small spots at the sides of the abdomen, black; thorax nearly impunctate ; elytra convex, without

depression, distinctly punctured at the base only.

Length 23 lines.

Head strongly constricted behind the eyes, the latter deeply notched, the lateral grooves also very deep; labrum

BIOL. CENTR.-AMER., Coleopt., Vol. VI. Pt. 1, Suppl., August 1888. e

26 PHYTOPHAGA.—SUPPLEMENT.

piceous; antenne half the length of the body, black, the basal joint fulvous, the third and following joints

rather slender and each longer than broad ; thorax rather longer than broad, the sides somewhat deeply

constricted, the basal sulcation obsolete, the surface obscure fulvous, with some nearly obsolete longitudinal

black spots at the sides, the disc impunctate ; scutellum fulvous ; elytra convex, subcylindrical, without any

trace of a basal depression, the punctuation only well-marked anteriorly near the suture, the rest of the

disc very finely and obsoletely punctured, the interstices flat ; underside fulvous, the knees, the apical

third of the tibie, the tarsi, and a small spot at the side of each abdominal segment, black.

Hab. Panama, David in Chiriqui (Champion).

A single specimen. On account of the filiform (not widened) joints of the antenne I

am unable to treat this insect as a variety of L. varipes or L. nupta; the upper surface

immaculate, and the apices only of the tibie (instead of the middle portion, as in

L. intricata) are black. In the sculpture and shape of the elytra this species very

closely resembles L. intricata.

86 (c). Lema modesta.

Pale fulvous ; labrum piceous ; antenna with shortened terminal joints; thorax longer than broad, impunctate ;

elytra convex, distinctly punctured towards the base only, the rest of the surface very finely punctate ;

underside and legs obscure fulvous, the abdomen lighter.

Length 23 lines.

Hab. Panama, Bugaba (Champion).

This insect is closely allied to L. immaculipennis, but I believe distinct; it differs |

thus:—the antenne are entirely fulvous, and the terminal joints (instead of being

elongate) are short and gradually, but slightly, thickened; the thorax is longer, and

the underside and legs are without black spots.

The elytra are shaped and sculptured exactly as in L. mmaculipennis.

A single specimen only was obtained.

Lema atricornis (p. 9).

To the locality Mexico, add:—Playa Vicente (SaJlé).

Lema sexnotata (p. 9).

To the locality Mexico, add :—Jalapa, Cordova (Hége), Vera Cruz (Sallé).

39 (a). Lema intricata.

Fulvous, the antenne, four spots on the head, a spot on each side of the thorax, and the scutellum, black ;

elytra strongly punctate-striate, a spot at the sides before and another below the middle, and a sutural

spot below the base, black ; breast with two spots ; legs black at the base, at the knees, and at the middle

of the tibise.

Length 24 lines.

Head impunctate, fulvous, the space round the eyes punctured, the vertex with a central black spot, the base

with three spots placed transversely ; antenne less than half the length of the body, black, the basal

joint fulvous ; thorax not longer than broad, deeply constricted at the sides, the basal groove rather deep,

the surface with a few minute punctures at the middle of the disc, the sides with a black spot at the middle

LEMA. 27

of the constriction; scutellum black; elytra deeply punctate-striate, the punctures indistinct below the

middle, the ninth stria entire, the interstices rather convex at the apex, the three spots placed thus—one

on the suture below the base, one, a little lower down, at the sides, and one below the middle at the centre

of the disc; underside and legs fulvous, the breast with a spot in front and another behind at the sides,

the femora at the base, the knees, a band at the middle of the tibie, and the tarsi, black.

Hab. Mexico, Oaxaca (Salié).

L. intricata may be recognized by the position of the elytral spots and by the black

mark surrounding the tibie. The spots at the base of the head are occasionally absent,

and of the elytral spots sometimes only the posterior ones are present ; the legs, however,

agree in coloration in all the specimens I have for examination. The uninterrupted

ninth elytral stria and the system of coloration places the species near L. sexnotata.

89 (s). Lema rugifrons.

Elongate, subdepressed, black; above fulvous; the head with three tubercles; thorax subcylindrical, punctured

anteriorly and on the disc; elytra strongly punctate-striate, the ninth row entire, fulvous, the suture to

beyond the middle, and a spot on the shoulders, black.

Var. Elytra entirely fulvous.

Length 12 line.

Head reddish-fulvous, the space between the eyes occupied by irregularly shaped tubercles (two lateral and one

central), the space between the tubercles irregularly rugose and clothed with some yellow pubescence ; eyes

distinctly notched ; labrum and mandibles black ; antennse half the length of the body, gradually thick-

ened towards the apical joints, entirely black ; thorax longer than broad, subcylindrical, widened in front,

the sides moderately constricted, the basal sulcation distinct and with a small central fovea at the middle,

the surface with a row of punctures on the middle of the disc and some punctures near the anterior margin

at the sides; scutellum obscure fulvous; elytra rather flattened, without basal depression, the punctuation

deep and regular but shallower behind, the outer interstices costate towards the apex, the ninth row of

punctures uninterrupted, the suture at the base, or to below the middle, black, the shoulders with a small

black spot; the underside and the legs black.

Hab. Guaremata, San Gerénimo (Champion).

On account of the sculpture of the head this very distinct species differs from all

others of our region; it belongs to the division with the ninth stria of the elytra entire.

Lema nigromaculata (p. 9).

To the locality given, add:—GuatemaLa (mus. Stuttgart), Las Mercedes, Zapote

(Champion).

The specimens obtained at the above localities differ from the type in the elytra

being devoid of the sutural spot, and also of the transverse posterior band, so that only

a small humeral and a small apical spot remain (a single specimen from Zapote is

without any spots whatever) ; and in the underside being more largely marked with black.

The chief characters for L. nigromaculata are the black sides of the breast and abdomen ~

and the black upper margin of the femora in connection with the uninterrupted ninth

row of punctures on the elytra. The Guatemalan specimens do not differ in any other

way whatever from the type.

28 PHYTOPHAGA.—SUPPLEMENT.

Lema godmani (p. 9).

To the locality given, add:—Mexico, Toxpam, Tuxtla (Sallé); GuatemMaua, Senahu

in Vera Paz (Champion).

Although the Mexican and Guatemalan specimens of this species, since received, are

for the most part of larger size (3 lines) than the type from Nicaragua, they agree in

all other respects with it; Z. godmani no doubt represents a really distinct species

amongst the several similarly coloured forms with uninterrupted ninth elytral stria. In

one specimen the abdomen, as well as the sides of the breast, is black.

Lema hexastigma (p. 10).

Lema scutaria, huj. op. p. 10.

To the locality Mexico, add :—Oaxaca, Toxpam, Cordova, Vera Cruz, Puebla (Sallé),

Orizaba (F. D. Godman & H. H. Smith).

This is a very variable species, of which Lacordaire had only the single specimen which

served him for his type. From the material now before me I have come to the con-

clusion that Z. scutaria must be considered a variety of L. hexastigma. I have, how-

ever, only seen a single specimen (from Puebla) entirely agreeing with Lacordaire’s

description ; in all the others the neck is not marked with black, and in many the suture

is entirely black, or black only at the base (as in the type of ZL. scutaria); the elytral

spots vary greatly in size in the different specimens, being sometimes connected at the

suture and forming almost transverse bands and sometimes very small, the several inter-

mediate stages proving the variability of the species. In all our examples, however,

the breast is entirely, or partially, black, and the base of the femora is fulvous.

Lacordaire had a specimen before him which had no sutural black stripe. The deep

depression at the base of the elytra (mentioned in the description of L. scutaria) is

present more or less distinctly in all the specimens. It seems to me doubtful whether

L. hexastigma itself is anything more than a variety of the North-American L. sea-

punctata, Oliv., typical examples of which I have not seen.

45 (a). Lema ancoralis.

Testaceous, the breast black ; thorax scarcely longer than broad; elytra indistinctly depressed below the base,

deeply punctured, the ninth row interrupted, a spot at the shoulder, a subtriangular patch at the base,

and a broad transverse band below the middle, connected at the suture, black ; legs pale.

Var. a. Elytra with the suture, a small spot at the shoulder, one before and another below the middle, black.

Var. 6. Elytra immaculate.

Length 13-27 lines.

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

At first sight, LZ. ancoralis seems again to represent only another variety of L. hexa-

stigma, and I regarded it as such at the first examination ; but the nine specimens before

LEMA. 29

me agree so well in the differences pointed out below that I am compelled to treat the

insect as specifically distinct. The head is not marked, either posteriorly or anteriorly,

with black (thus differing from several species described by Lacordaire, e. g. L. septem-

punctata, L. septem-plagiata, &c.) ; the antenne are pale or pale fuscous (not black as

in the allied species); and the elytra in the typical form have a black anchor-shaped

patch connected at the suture with a broad posterior band (resembling in this respect

L. dorsalis, L. gracilis, and allied forms, in which, however, these marks are blue).

The principal difference between L. ancoralis and L. hexastigma and its varieties is to

be found in the pale testaceous legs and tibie, this coloration being constant in all the

specimens from Bugaba; and in the basal depression of the elytra being very shallow.

The var. a. resembles closely in the markings of the elytra L. hexastigma, and can only

be separated by the colour of the antenne and legs; while var. 6., although agreeing in

every other way with the type, is entirely devoid of any black markings. In the costate

apical interstices and the deep punctures of the elytra this species closely resembles

LL. hexastigma.

45 (s). Lema laticollis.

Testaceous, the antenna, the lower part of the face, and the tibiz black ; thorax subquadrate; elytra strongly

punctate-striate, the suture, a spot at the shoulder, another before the middle, and a third near the apex,

black.

Var. Elytra with the suture black towards the base only ; the two posterior spots obsolete.

Length 2 lines.

Hab. Mexico, Cordova, Vera Cruz (Sal/é).

Four specimens. J. laticollis cannot be treated as a variety of L. heaastigma, on

account of the following differences:—The clypeus and the labrum are black; the

thorax is less elongate (being slightly broader than long), and its sides are but very

moderately constricted; the elytra (though marked and punctured in the same way as

in L. hewastigma) have their basal depression shallower; the underside and the femora

are entirely testaceous or flavous; and the posterior femora extend very nearly to the

end of the abdomen. The ninth row of punctures on the elytra is, as in L. ancoralis,

largely interrupted and costiform.

45 (c). Lema palmeri.

Black ; antenne very short, the apical joints obscure fulvous ; thorax finely punctured, bi-impressed, the sides

black, the rest of the surface testaceous; elytra testaceous, deeply punctured, the suture and a shert

humeral streak, black; legs testiaceous, the femora with a black spot.

Length 2 lines.

Head impunctate ‘at the vertex, black, the lower portion rugose, covered with pubescence ; antenne extremely

short, not extending beyond the base of the thorax, all the joints short, the first and the terminal four

joints fulvous, the others black; thorax subquadrate, testaceous, the sides black, the basilar sulcation

well-marked, the surface with a double row of punctures on the disc, some scattered punctures near the

anterior angles, and two short longitudinal fovee near the anterior margin; scutellum black; elytra

without basal depression, deeply and closely punctate-striate, the ninth row entire, the interstices slightly

30 PHYTOPHAGA.—SUPPLEMENT.

costate near the apex, a narrow sutural stripe extending from the base to the apex, and a short streak at

the shoulders, black; underside black ; legs fulvous, all the femora with a black median spot.

Hab. Mexico, near the city (Dr. Palmer).

Of this species, remarkable for its short antenne and the rugose lower portion of the

head, only a single specimen was obtained.

45 (p). Lema insularis. (Tab. XXXV. fig. 20.)

Fulvous, the head, antenne (the last three joints excepted), and breast black ; elytra testaceous, a short stripe

at the shoulder, an elongate spot surrounding the scutellum, and a transverse band below the middle of

each, bluish-black, the ninth row of punctures entire.

Length 4 lines.

Head impunctate, black, the neck fulvous; antenne slender, half the length of the body, the three lower joints

stained with fulvous, the three apical ones flavous, the others black, the fourth joint one half longer than

the third; thorax slightly longer than broad, deeply constricted at the middle, the surface impunctate, the

basilar sulcation shallow; elytra with a slight depression below the base, distinctly punctured anteriorly,

almost entirely impunctate below the middle, the interstices very slightly convex towards the apex, the

markings arranged thus—a humeral stripe extending to one third of the elytral length and widened at

its lower extremity, a scutellar spot (common to both elytra) slightly shorter than the lateral one, and a

posterior transverse band not quite extending to either margin; legs and abdomen fulvous.

Hab. Panama, Taboga Island (Champion).

Very closely allied to the Colombian L. divalis, Clark, and possibly only a variety of

that species; it differs in having the last three (instead of the last four) joints of the

antenne flavous and in the fulvous (not black) legs. A single specimen only was

obtained.

45 (x). Lema incisa. (Tab. XXXV. fig. 24.)

Piceous, the head and breast entirely, or partly, black ; antenne obscure fulvous; thorax deeply grooved at

the base, the latter flavous; elytra depressed below the base, strongly punctate-striate, the anterior portion

piceous, the posterior portion flavous, the ninth row of punctures entire.

Length 24-3 lines.

Head entirely impunctate, not constricted behind the eyes, piceous or black, the extreme base more or less

fulvous, the space surrounding the eyes almost entirely impunctate ; antenne fulvous, the terminal joints

sometimes darker, the third and fourth joints equal and each much longer than the second; thorax

transverse, short, at least twice as broad as long, deeply constricted at the sides, the anterior angles

slightly tuberculiform, the basilar groove very deep, the basal portion flavous, the” anterior portion dark

brown and with a few fine scattered punctures; scutellum brown at the base, black at the apex; elytra

with a shallow depression below the base, the shoulders prominent, the punctuation rather deep anteriorly

and diminishing gradually towards the apex, the ground-colour flavous, the anterior half occupied by a

subquadrate piceous patch which does not extend to the shoulders nor to the lateral margins and is of a

browner tint near the suture ; the breast black, the abdomen piceous, the legs fulvous.

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

I know of no described species with which the present insect can be compared. The

deep thoracic groove and the pattern and colour of the elytra will readily distinguish

i. incisa,

LEMA. 31

45 (r). Lema variegata.

Head, the basal joints of the antenne, the breast, and the tibie, black ; thorax rufous; elytra pale yellow, a

transverse band at the base, the suture narrowly, and a small spot below the middle, bluish-black, the

ninth row of punctures entire.

Length 23 lines.

Head black, impunctate, the space surrounding the eyes punctured; antennz obscure fulvous, the basal joint

entirely black, the three following joints blackish above, the third joint distinctly shorter than the fourth ;

thorax subquadrate, deeply constricted at the sides, rufous, the basilar groove not very deep, the middle of

the dise with a few very fine punctures; scutellum black ; elytra convex, without basal depression, the

anterior third deeply, the rest very finely, punctured, the surface pale yellowish, the markings arranged

thus—the base occupied by a transverse bluish-black band which does not extend to the lateral margin

and has its posterior edge rather deeply bi-emarginate, the suture narrowly bluish-black, this colour

slightly widened out at the middle into a lozenge-shaped mark, and below this is a small dark spot; the

breast black, the abdomen and femora flavous, the tibize and tarsi black.

Hab. GuatTEMALA (coll. Jacoby).

I possess a single specimen of this rather curiously-marked species, without more

particular locality.

Lema discoidalis (p. 11).

To the locality given, add :—Mexico, Cosamaloapam, Vera Cruz (SaJ/é).

It is probable that the specimen from Guatemala which served me for the type is

somewhat immature, and that it represents a variety in which the two triangular elytral

patches have united. ‘The Mexican examples are reddish-fulvous and have the elytral

markings more or less isolated (though sometimes connected by a narrow sutural stripe),

and the punctuation finer and more regular; in other respects they agree with the type.

L. discoidalis may be known from its allies by the blackish colour of the elytral markings,

the immaculate humeri, and the entirely fulvous underside and femora.

46 (a). Lema permutans.

Rufous, the antenne (the first joint excepted), the sides of the breast, the apices of the femora, and the tibie

and tarsi black; elytra deeply depressed below the base, subfoveolate-striate, a large triangular spot at

the base, and a small spot below the middle, black.

Var. The elytral spots small and of equal size.

Length 2 lines.

Head not constricted behind the eyes, impunctate; antenns about half the length of the body, black, the basal

joint fulvous; thorax rather broader than long, not very deeply constricted at the middle, the basilar

groove well-defined, the surface with a few fine punctures; elytra with a deep depression below the base,

the punctures very deep and large, the interstices near the base and within the depression swollen and

somewhat irregular and towards the apex subcostate, the punctures distinct but becoming much finer

behind, the ninth row largely interrupted at the middle; below fulvous, the sides of the breast, the upper

edges of the four anterior and the apices of the posterior femora, and the tibie and tarsi, black.

Hab. Mexico, Teapa, Vera Cruz (Sallé); Nicaragua, Chontales (Janson).

L. permutans belongs to Lacordaire’s twenty-eighth group, and on account of the

deep punctuation of the elytra seems closely allied to the North-American L. ephippium ;

32 PHYTOPHAGA.—SUPPLEMENT.

it differs, however, from that species in its entirely fulvous head and in the shape of the

elytral markings. From the other closely allied forms of the same group L. permutans

may be known by the black (not blue) colour of the markings, the want of the humeral

spot, and the deep punctures of the elytra, and other details pointed out in the above

description. The variety differs from the type in the elytral spots being smaller—one

is placed within the depression and the other below the middle; other differences I am

not able to find.

Clark’s species was unfortunately overlooked by me and described under a new name.

It may be known from Z. maculipennis by the much more coarsely punctured elytra

and by the want of the black shoulder-spot. It is, however, not correct to say, as

Clark does in his description, that the punctuation is ‘‘ unarranged ”—neither in the

type nor in the other specimens before me is this the case; all that can be said is that

the interstices within the deep fovea below the base of the elytra are rather swollen,

the linear arrangement of the punctures (as in most other species of Lema) being

perfectly clear. Some specimens have a black spot placed within the elytral depression,

but in others this is absent. Iam unable to find any trace of a fuscous spot at the

sides of the thorax or of the similarly-coloured elytral punctures mentioned by Clark.

The form with a single black spot within the elytral depression was described by me in

the earlier part of this work under the name of L. hégei.

L,. albini is evidently a very variable species and is considered by Crotch (Proc. Ac.

Phil. 1873, p. 26) to be a variety of L. serpunctata, Oliv., with which I am inclined to

agree. The elytral spots are very variable in size and also in number: in the true

L. sexpunctata there are three spots on each elytron; in L. aldini these spots are larger

—the sutural with the corresponding one on the opposite elytron is confluent (together

forming a triangular patch), and the posterior one assumes the shape of a transverse

band. In these forms of L. albinj the sides of the breast and a@ spot on the first

LEMA. 33

abdominal segment are black; but examples with entirely fulvous underside are not

rare. The legs in all, with the exception of the femora being fulvous at the base, are

black. There are some specimens before me which have only one small black spot

below the base of the elytra, but the other differences (if any) are so slight that I

cannot treat these examples as representing distinct species; in this case, as in many

other instances, it is almost impossible to draw the line between species and variety.

49 (a). Lema pardalina.

Fulvous, the antenne (the fulvous basal joint excepted), the apices of the femora, and the tibie and tarsi black ;

elytra deeply and remotely punctate-striate, with a fovea below the base, the suture anteriorly, a spot on

the shoulder, two spots placed obliquely below the base, and one below the middle, black.

Var, The sutural and humeral spots wanting.

Length 23 lines.

Hab. Mexico, Vera Cruz, Cordova (Sallé).

I cannot treat this as a variety of L. sexpunctata, to which, however, it is closely

allied; the differences are as follows:—The thorax is slightly shorter; the elytra have

their punctures deeper and more remotely placed, the fovea is situated close to the

suture, the latter is black for a short distance near the base, and there is an extra black

spot placed a little lower down than the one within the fovea (this spot is always absent

in all the specimens I refer to L. sexpunctata) at the sides below the base. The entire

underside is fulvous; and the elytral punctuation is very fine below the middle. The

three specimens before me only differ from each other in the spot on the shoulder and

suture of the elytra being obsolete in one of them.

49 (c). Lema flavipennis.

Pale flavous, the antenna, labrum, tibiz, and tarsi black; thorax subquadrate, rather transverse; elytra very

Of rather broad general shape; the head impunctate, with a short longitudinal groove between the eyes, the

latter somewhat deeply indented; labrum and mandibles black; antenne slender, two thirds the length

of the body, black, the third and fourth joints equal; thorax almost broader than long, the sides very

moderately constricted at the middle, the basilar groove not strongly marked (in one specimen with a

central depression) ; elytra much broader than the thorax, rather flattened, almost imperceptibly depressed

below the base, pale flavous, deeply and regularly punctate-striate anteriorly, the punctuation becoming

more feeble behind, the interstices costiform towards the apex, the ninth row of punctures only visible on

the apical third; breast brownish, covered with thin pubescence; posterior femora extending to the apex

of the elytra; the tibice and tarsi black.

34 PHYTOPHAGA.—SUPPLEMENT.

L. flavipennis seems to belong to Lacordaire’s thirty-first group, and is no doubt

closely allied to L. simples, L. ferrugata, and L. helvola. It seems to differ, however,

from all of these in the want of the basal depression of the elytra, the scarcely con-

stricted sides of the thorax, and the entirely black antenne. In one specimen the

space surrounding the inner margin of the eyes is black. ‘The space at the sides of the

elytra occupied by a remnant of the ninth row of punctures is broad, smooth, and

costiform.

49 (p). Lema planipennis.

Fulvous, the five basal joints of the antenne, the labrum, the apices of the tibia, and the tarsi black; thorax

with some fine punctures on the disc; elytra metallic green, flat, without basal depression, strongly and

regularly punctured, the interstices costate at the apex, the ninth row of punctures interrupted.

Length 2 lines.

Head with a short fovea between the eyes, the latter not very deeply notched, the space in front clothed with

yellow pubescence; labrum black; antenne about half the length of the body, the six apical joints

fulvous, the others black ; thorax very slightly longer than broad, scarcely constricted at the sides, the basal

sulcation not very deep, the disc with two rows of fine punctures at the middle and some other punctures

near the sides anteriorly; scutellum fulvous; elytra somewhat flattened, without basal depression, very

regularly and deeply punctured throughout, the interstices at the apex and at the sides costate.

Hab. Muxico, Ventanas in Durango (forrer).

L have no doubt about the specific distinction of this insect, although I have only a

single specimen for examination. ‘The colour of the antenne, the scarcely constricted

thorax, the unimpressed base of the elytra, and their deeply impressed and regular strie

of punctures visible to the apex, form characters by which L. planipennis may be

recognized with comparative ease.

49 (n). Lema approximata.

Flavous, the head, antenne, tibie, and tarsi black ; thorax subcylindrical; elytra testaceous, the apex greenish,

subgeminate punctate-striate, a broad sutural and a broad lateral stripe, black, the ninth row of punctures

interrupted.

Length 2 lines.

Head black, the neck fulvous; the vertex with a narrow central groove; eyes deeply notched, the lateral

grooves deep; antenne half the length of the body, entirely black; thorax subcylindrical, fulvous,

slightly longer than broad, the sides moderately constricted, the basal sulcation distinct but not deeply

impressed, the surface impunctate; scutellum black; elytra narrowed posteriorly, with a very obsolete

depression below the base, the punctuation anteriorly arranged in double rows, the interstices towards

the apex very broad and costate, the punctures nearly obsolete behind, the ninth row only distinct

anteriorly, with a broad sutural and a broad lateral longitudinal black stripe, the latter at the shoulder

widening into a subquadrate spot; underside entirely flavous, covered with fine silvery pubescence; tibiae

and tarsi black. the posterior tibiee slightly curved.

Had. Guatemata, Torola (Champion); Panama, Taboga Island (Champion).

This species seems closely allied to the Colombian L. marginata, Oliv. ; the head and

antenne, however, are entirely black; and the elytra have their punctures somewhat

arranged in double rows, and are more or less greenish towards the apex. In the

female the antenne are shorter than in the male.

LEMA. 35

49 (Fr). Lema cinctipennis.

Piceous, the head and antenne (the first joint excepted) black; thorax fulvous, scarcely constricted at the

sides; elytra flavous, deeply punctate-striate, without basal depression, a sutural and a sublateral longi-

tudinal stripe, abbreviated at the apex, black; legs fulvous.

Length 2 lines.

Head entirely black, with a small central fovea; palpi fulvous; antenne two thirds the length of the body,

black, the first joint fulvous; thorax subquadrate, scarcely constricted at the sides, the basal sulcation

obsolete, the surface impunctate, fulvous; scutellum piceous; elytra very deeply punctured, without

depression, the interstices costate at the sides and at the apex, the ninth row of punctures interrupted,

the suture narrowly and a broader sublateral stripe, both abbreviated before the apex, black; the under-

side piceous, covered with fine yellowish pubescence; legs fulvous.

Hab. Mexico, Panistlahuaca (Sal/é).

There is only a single specimen of this insect contained in the Sallé collection. From

_L. approximata it is sufficiently distinguished by the scarcely constricted thorax, the

deep punctures and colour of the elytra, and the colour of the underside and legs;

both species should be placed near L. marginata.

Lema longicornis (p. 12).

Zunil, Volcan de Atitlan, Torola, Tamahu (Champion); Nicaraeva, Chontales (Janson,

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

As already remarked, it is very probable that L. longicornis and the present species

are not specifically distinct; at any rate I am not able to separate the numerous

examples before me from the above localities in a satisfactory way. The elytral pattern

is subject to great variation, the two large blue patches being often confluent and

occupying nearly the entire disc. Guatemalan specimens differ from most of those

received from Mexico in having the breast black, but Mexican examples also occur

with the breast similarly coloured. All the specimens I refer to Z. dorsalis agree,

however, in the elytra being deeply depressed below the base, with the interrupted

ninth row of punctures costate, and the patches of a metallic blue colour; and also in

the femora being black at the apex and fulvous at the base. JZ. dorsalis and L. longi-

cornis vary considerably in size and in the intensity of the punctuation.

Amongst the great number of specimens before me with fulvous head and thorax,

metallic blue elytra, and black underside, it is almost impossible to come to a conclusive

opinion in regard to the number of species which they represent, or which of them

may be the true L. plumbea, Lac. The examples I refer to L. plumbea have the under

surface, antenne, and legs (the base of the femora excepted) black; and the elytra

violaceous-blue, with a feeble basal depression, and deeply punctured strie. Some

specimens lately obtained by Messrs. Smith and Godman at Orizaba are of a more

greenish tint above, and are rather smaller and more narrowed posteriorly, and have

the black colour of the lower portion of the head extending upwards between the

antenne ; possibly these may represent another species.

54 (a). Lema yucatana. ,

Rufous, the labrum, antenne (the first joint excepted), the apices of the tibie, and the tarsi black; thorax sub-

quadrate, moderately constricted ; elytra without basal depression, strongly punctate-striate, the ninth »

row entire.

Length 12 line.

Head impunctate, constricted behind the eyes, the latter prominent and deeply notched ; the labrum and mandi-

bles black; antenne: half the length of the body, black, the basal joint fulvous ; thorax scarcely longer than

broad, moderately constricted at the sides, wider in front than behind, the surface with a few very minute

punctures (only visible under a strong lens); scutellum black ; elytra subcylindrical, without any trace of

a basal depression, deeply and regularly punctate-striate, the ninth row uninterrupted, the interstices

strongly costate towards the apex; the posterior femora strongly thickened, reaching nearly to the end

of the abdomen.

Hab. Mexico, Temax in N. Yucatan (Gaumer).

A single specimen. This species belongs to the first division of Lacordaire’s mono-

graph, it having the ninth row of elytral punctures uninterrupted. JL. yucatana may be

recognized by its small size, the anteriorly widened thorax, and the colour of the

antenne.

55. Lema guatemalensis.

Lema pudens, huj. op. p. 13 (nec Lacord.).

To the Guatemalan localities given, add :—Panajachel, Senahu (Champion).

The specimens referred by me (ante, p.13) to L. pudens proving to belong to another

species, I now describe it :—

Black, the extreme base of the femora, the upper portion of the head, and the thorax fulvous ; the latter

impunctate ; elytra dark metallic blue, with a distinct oblique depression below the base, strongly punc-

tured anteriorly, finely so posteriorly.

Length 2-22 lines.

I am obliged to separate this species from L. plumbea on account of the very distinct

basal depression and the different system of punctuation of the elytra, the punctures

being less closely placed and much finer posteriorly. Lacordaire says nothing about a

basal depression in L. plumbea or L. pudens and only speaks of the longitudinal groove

within the shoulder, whereas in L. guatemalensis the elytra are distinctly depressed below

LEMA. af

the base. The head in the latter is frequently marked with black between the antenne.

Some of the specimens before me, however, I am not able to refer with certainty to either

species, and it is very doubtful whether the present insect is anything but a local variety

of L. plumbea. Lacordaire gives Bahia as the locality for L. pudens.

55 (a). Lema eremita.

Rufous, the antenne (the first joint excepted) black; thorax scarcely constricted at the sides, longer than

broad; elytra distinctly depressed below the base, dark blue, strongly punctured, the interstices costate at

the apex, the ninth row of punctures interrupted.

Length 2 lines.

Head not constricted behind, impunctate, rufous; the eyes not deeply notched; the labrum black; antenne

half the length of the body, black, the first joint rufous; thorax slightly longer than broad, the sides very

little constricted at the middle, the basal sulcation moderately deep, the surface impunctate, rufous;

scutellum rufous; elytra with a small but rather deep depression below the base, the punctuation very

regular and more deeply impressed anteriorly than towards the apex, the interstices costate behind, the

ninth row of punctures interrupted for a short distance below the middle; underside and legs rufous, the

tibie slightly darker at the apex.

Hab. Mexico, Tuxtla, San Miguel, Vera Cruz (Sailé), Jalapa (Hoge); Bririsu

Hoypvras, R. Hondo (Blancaneaur).

It will be comparatively easy to distinguish L. eremita from other similarly-coloured

species, on account of the feebly constricted thorax and the distinct basal depression of

the elytra in connection with the rufous underside and legs. Amongst the small species

with blue elytra L. eremita differs entirely in the shape of its thorax.

55 (B). Lema illigeri.

Rufous, the antenne (the first two joints excepted) black; thorax subquadrate, slightly constricted; elytra

without basal depression, dark metallic blue, strongly punctured, the ninth row slightly interrupted

below the middle.

Length 2 lines.

Head impunctate, with a short central fovea, the lateral grooves deep, the eyes but slightly notched; antennz

about half the length of the body, fuscous, the lower two and the base of the third and fourth joints

fulvous; thorax scarcely longer than broad, very slightly constricted at the middle, the basal groove

distinct in the centre only, the surface impunctate; scutellum fulvous; elytra subcylindrical, without

depression below the base, closely and coarsely punctate-striate, the interstices strongly longitudinally

costate behind, the ninth row very slightly interrupted below the middle; underside and legs rufous, the

apices of the tibize and the tarsi stained with fuscous.

Hab. Mexico, Temax in N. Yucatan (Gaumer).

L. illigeri seems closely allied to L. eremita, but differs from this and several other

similarly-coloured species in the want of an elytral depression below the base and in

the not very distinctly interrupted ninth row of punctures. The last-named character,

generally so well-marked in the species of Lema belonging to the second division of

Lacordaire, is here very indistinct (the extent of the interruption being confined to

about the length of two punctures); this character, therefore, in connection with the

slightly constricted thorax and the deep punctures of the elytra, the latter without

38 PHYTOPHAGA.—SUPPLEMENT.

depression, will enable L. illigeri to be more readily recognized. In a single specimen,

also obtained in Yucatan, and which possibly represents another closely allied species,

the posterior femora are strongly thickened and have a black streak on their inner side,

the breast has (on one side) a black mark, and the head several black spots; but these

markings are possibly abnormal.

55 (c). Lema jalapensis.

Reddish-fulvous, the clypeus, labrum, antenne, and legs (the base of the femora excepted) black; thorax

impunctate; elytra metallic blue, deeply impressed below the base, strongly punctured, the interstices

flat, the ninth row of punctures interrupted.

Length 23 lines.

Hab. Mexico, Jalapa (Hége).

L. jalapensis has the general appearance of L. eremita ; it differs principally in the

thorax being deeply constricted at the sides, and the anterior portion diverging strongly

outwards, and having (as in Z. sallei and L. guatemalensis) a small tubercle placed at

the anterior angles. From the two last-named species L. jalapensis may be separated

by the fulvous underside and base of the femora. The elytra have a deep (but small)

depression below the base, the punctures are not very closely placed, and the interstices

are flat. The antenne are entirely black. From ZL. guatemalensis the species is distin-

guished by its larger size and the much deeper elytral depression.

55 (p). Lema spectabilis.

Black, the head, the basal joints of the antenne, thorax, and legs fulvous; elytra metallic blue, the base with

a short and deep depression, strongly punctured, the ninth row interrupted.

Length 2 lines.

Head entirely fulvous; the eyes somewhat deeply notched, the space surrounding them somewhat rugose ;

antenne proportionately short, the third joint shorter than the fourth, the three or four lower joints (in

one specimen nearly all the joints) fulvous, the others black; thorax not longer than broad, the sides

moderately constricted, the basal groove distinct but not deep, the surface impunctate, fulvous; scutellum

fuivous; elytra with a short but rather deep depression below the base, somewhat strongly punctured

anteriorly and much more finely so towards the apex, the ninth row of punctures interrupted for a short

distance; underside and legs entirely fulvous.

Hab. Mexico, Cuernavaca (Sallé).

Two specimens. JL. spectabilis may perhaps best be compared with ZL. eremita, on

account of the thorax, though shorter, being feebly constricted at the sides; it also

differs in the fulvous (not black) labrum, the colour of the antenne (in one specimen

the six, in the other the four, basal joints are fulvous), and the black (not fulvous)

under surface. |

55 (z). Lema sallei.

Black, the head (the clypeus excepted) and thorax rufous; thorax with the anterior angles acute; elytra

posteriorly, the ninth row interrupted.

Length 2} lines.

Hab. Mexico, Toxpam (Saillé), Jalapa, Cordova (Hége); GuaTemaua, Llano grande

(mus. Stuttgart); Costa Rica (Van Patten).

It is with considerable hesitation that I describe the present insect as new, it being

extremely near to two of the species included by Lacordaire in his twenty-ninth group ;

yet I cannot identify it with either. In Z. sall@i the antenne are entirely black (the

first two joints are sometimes slightly stained with fulvous below, but never above), the

species differing in this respect from L. dichroa, L. tricolor, and others; the head is

rufous (with the exception of the black epistome); the anterior margin of the thorax is

acute at the sides, that is, a small pointed tubercle is visible when the insect is viewed

from above (this is absent in most of the other similarly-coloured species); the elytra

have a deep basal depression (absent in L. plumbea); and the legs are entirely black,

with the exception of the extreme base of the femora being sometimes slightly stained

with fulvous. JZ. guatemalensis has a similar tubercle at the sides of the thorax, but

is smaller in size, and the elytra have the depression at their base shallower (the base

itself in consequence less elevated) and their punctuation much stronger; the two

species, however, are very closely allied, and it is possible that they may not be really

distinct.

This species was overlooked by me in the earlier part of this work; it should follow

L. inquinata, Lac. Clark makes no mention of a deep depression below the base of

Head rather broad, constricted behind the eyes, the lateral grooves very deep; the vertex with two rounded

tubercles, which are divided by a longitudinal groove ; eyes slightly notched, very large and prominent, the

the female, black, the third and fourth joints equal; thorax slightly broader than long, deeply constricted

at the sides, the basal sulcation also rather deep, the anterior angles rounded, the surface entirely impunc-

tate; scutellum black; elytra with a deep longitudinal depression within the shoulders and an equally

deep transverse depression below the base, the latter distinctly raised, the punctuation rather fine and

L. foveipennis approaches L. fryi, Clark, a species placed by me at the beginning of

the genus, from which it is separated by the deep transverse elytral depression, long

antenne, and the wart of the small rufous spots on the head. LL. violacea, Lac., and

L. cerulea, Lac., are larger, the former having more strongly developed femora, and the

latter a differently shaped head; Z. lepida, Lac., has the head rufous in front, and the

eyes deeply notched. Many specimens from the State of Panama, but one only from

Guatemala, and one from Mexico. ‘This latter does not differ from the others, except

in having (as is the case with so many other similarly-coloured species) two rufous

spots behind the eyes, and in the more violaceous colour of the elytra; in the absence

of other distinctive characters, I think it best to look upon the Mexican form asa

variety of L. foveipennis.

I am not able to refer with certainty the specimens before me from the above

localities to this or to any one of the several closely allied species described by

Lacordaire; all are apparently subject to a good deal of variation. They agree with

the description of Z. azuretpennis in having the first two joints of the antenne red, but

in a few examples the first joint only is of that colour. The elytra are either metallic

blue or violet, and have a deep basal depression; their punctuation is much finer than

in most of the other similarly-coloured species of our region, the apex being almost

impunctate, and the ninth row interrupted. In most specimens the colour of the

underside is black, but in a few (which differ in no other way) it is fulvous: this

variation prevents the certain identification of the species with any one of those

included in Lacordaire’s monograph. The present insect varies in size from 14 to 2

lines; and the legs vary in colour from black to fulvous, but are usually of the latter

colour with the tibiz darker; it has the third joint of the antenne shorter than the

fourth, and the elytral punctures are rather distantly placed.

60 (c). Lema bisulcata.

Black, the head rufous at the base; thorax finely punctured on the disc, sulcate in front and at the base; elytra

metallic blue, with a deep basal depression, very strongly punctate-striate, the ninth row interrupted.

Length 14-2 lines.

LEMA. 4]

Head constricted towards the base, rather elongate, impunctate; the eyes large and prominent, and somewhat

deeply notched, bounded behind by a narrow transverse rufous band, and with a short longitudinal groove

in the middle between them; antenne half the length of the body, thickened towards the apical joints,

black, the third joint slightly shorter than the fourth; thorax transverse, broader than long, the sides

rather deeply constricted at the middle, with a transverse groove (more distinctly visible at the sides) in

front of the anterior margin, and another (oblique at the sides) at some distance from thu base, the middle

of the disc impressed with a row of fine punctures; elytra slightly narrowed at the middle, deeply longi-

tudinally depressed within the shoulders and also below the base, the punctures very deep and rather

remotely placed, and those of the eighth row larger than the others, the ninth row interrupted in the middle,

the interstices costate at the apex; the underside and legs black.

Hab. Mexico, Jalapa (Hége).

L. bisulcata differs from the other species with blue elytra belonging to this division

in the structure of the antenne and the rufous band on the vertex, in connection with

the black head and thorax, the anterior sulcation of the latter, and the deep depression

and punctures of the elytra.

It cannot be mistaken for any other species with unicolorous upper surface.

60 (p). Lema brevicornis.

Black; above dark metallic blue; antenne very short and robust; thorax minutely punctured and finely

strigose; elytra without basal depression, very regularly punctate-striate, the ninth row of punctures

interrupted.

Head slightly constricted behind, the vertex impunctate; eyes moderately large, not deeply notched, bounded

behind by a transverse groove, the latter with two ill-defined rufous elevations in the middle, the entire

lower part of the face thickly covered with yellowish pubescence; antennez scarcely extending beyond

the base of the elytra, distinctly thickened towards the apex, all the joints robust and short; thorax

transverse, distinctly widened in front, the sides rather deeply constricted, the basal groove distinct, the

entire surface impressed with very fine punctures and strige, and of a bluish-green tint; scutellum black,

its apex deeply emarginate; elytra rather cylindrical, the basal depression almost obsolete, very regularly

and rather deeply punctured, the punctuation (as usual) becoming rather finer posteriorly, the ninth row

broadly interrupted (the anterior punctures composing it strongly, the posterior ones very finely, impressed) ;

underside covered with fine yellowish pubescence.

Hab. Mexico, Salazar (Hége).

A single specimen obtained by Herr Hoge during his second journey. This insect is

apparently a close ally of Z. fryi, Clark, but it cannot be identified with it, The very

short and robust antenne (which are similarly formed in L. fryi), in connection with

the finely punctured and rugose thorax and the much smaller general size, will separate

L. brevicornis from any other species of this division.

Lema mexicana (p. 14).

To the locality Mexico, add :—Puebla, El Mirador (Sal/é).

In the description of this species I have omitted to mention that the sides of the

head below the eyes are black: this seems to be a good and constant character by

which Z. mexicana may be separated from the allied forms with similar elytral pattern.

In the four specimens before me the head is thus coloured.

ninth row of punctures interrupted at the middle, the transverse blue bands placed thus— one (extending

to the sides and occupying about one fourth of the length of the elytra) at the base, and one (not extending

to the sides, and widened at the suture) near the apex; underside fulvous, the legs piceous or black with

a slight bluish gloss.

Hab. Mexico, Ventanas, Presidio (Furrer), Cordova (Sallé), Vera Cruz (H. H. Smith).

L. relucens cannot be mistaken for Z. mexicana, on account of the elytra being much

more strongly and closely punctured, and without basal depression, and the underside

and legs differently coloured. The species belongs, however, to the same division as

L. mexicana, it having the ninth row of elytral punctures interrupted. The seven

specimens before me agree in every way with each other.

63. Lema dilaticollis.

Obscure piceous or dark fulvous below; antenne (the first joint excepted) black; head and thorax fulvous

(both sometimes marked with fuscous); thorax widened anteriorly ; elytra dark blue or greenish, strongly

punctate-striate, the base without depression ; legs fulvous, the femora with an obscure piceous spot.

Length 2 lines.

Head rather elongate; the clypeus piceous, the vertex generally stained with the same colour; eyes deeply

notched ; antenne half the length of the body, black, the first joint, and sometimes the second also, fulvous ;

thorax rather broader than long, the sides somewhat deeply constricted at the middle, the anterior portion

distinctly widened towards the apex, the basal groove rather strongly marked, the surface impunctate ;

scutellum fulvous ; elytra narrowed towards the apex, with a scarcely visible depression below the base,

the latter not raised, the punctuation deep and strong anteriorly, but very finely impressed towards the

apex (where not more than six or seven rows are visible), the ninth row greatly interrupted at the

middle; the underside obscure piceous, the sides of the breast and the middle of the abdomen more or

less fulvous, clothed with fine silky pubescence: femora marked with an obscure fuscous spot at the

middle, the posterior pair robust and extending to the end of the abdomen; tarsi sometimes stained with

fuscous on their outer edge.

Hab. Mexico, Cordova, Toxpam (Sallé), Jalapa (Hoge); Guatemata, San Gerdénimo,

Cerro Zunil (Champion).

I am not able to satisfactorily identify this species with any of those included in the

twenty-ninth group of Lacordaire’s monograph. L. dilaticollis is distinguished amongst

its allies by the rather elongate head and the black or dark epistome; in some speci-

mens there is a dark marking on the vertex and two short longitudinal stripes on the

thorax. The sides of the thorax from the middle to the apex are strongly divergent,

so that the anterior margin is wider than the head (although the latter is not constricted

LEMA. 43°

behind the eyes); the elytra have a scarcely visible basal depression; and all the

femora have an obscure dark spot at the middle. One of the specimens from

Guatemala differs in having fulvous antenne and immaculate legs; but as it does not

differ in any other way I treat it as a variety of the same species. The robust femora

and the partly piceous and partly fulvous underside will assist in the recognition of

L. dilaticollis.

65. Lema sneipennis.

Obscure piceous, the antenne and the clypeus black ; thorax fulvous, spotted with black, the disc punctured ;

elytra seneous, deeply and remotely punctured, the apical margin testaceous, the space in front of it

thickened, the ninth row of punctures only indicated at the base and apex; legs testaceous, spotted

with fuscous.

Length 13 line.

Head impunctate, obscure fuscous at the vertex; eyes not deeply notched, the space between them bounded by

a deep transverse groove; labrum black, clothed with rather long whitish pubescence; antenne two

thirds the length of the body, black, the three or four basal joints testaceous at the base, the third and

fourth joints equal; thorax rather transverse, short, deeply constricted at the sides, the basal sulcation

also very deep, the surface obscure fulvous, with a greenish-zneous longitudinal band at the middle and

a short similar marking at each anterior angle, and a distinct transverse groove on each side within the

anterior margin, the middle of the disc and the sides anteriorly distinctly punctured; elytra with a

distinct depression below the base, bronze-coloured, the punctures deep and distantly placed, those near

the apex very fine and still more remote, the ninth row only indicated at the base and apex, by a few

punctures, the interspace near the lateral margin strongly swollen behind, the margin itself from the

middle to the apex narrowly testaceous; underside piceous, the sides of the abdominal segments more or

less fulvous; legs testaceous, the femora with a fuscous spot at the knees above.

Hab. Guatemata (coll. Jacoby).

Of this apparently very distinct species I have received a specimen from the Museum

of Stuttgart.

Too late to be fully noticed in their proper place we have received a large number of |

examples of many species of Lema from Mexico. Amongst these are the following two

new species :—

66. Lema ceruleo-plagiata.

Black ; head usually more or less fulvous in front ; elytra with a distinct basal depression, fulvous, a triangular

mark at the base, and a transverse band below the middle, metallic blue.

Var. The elytral spots more or less confluent.

Length 2 lines.

Hab. Mexico, Teapa in Tabasco, Atoyac in Vera Cruz (H. H. Smith).

Numerous specimens lately received from the above localities differ so much in

coloration from Z. dorsalis, L. longicornis, and several allied species, that I am obliged

to separate them. In ZL. cwruleo-plagiata the head is either entirely black or has the

front marked with fulvous to a greater or less extent; the antenne and the thorax

are entirely black, the latter being impunctate; the elytra are without a spot on the

shoulders; and, lastly, the entire underside and the legs are black. In the variety the

44 PHYTOPHAGA.—SUPPLEMENT.

entire elytral disc is occupied by the dark blue bands, the margin only being narrowly

fulvous. L. cewruleo-plagiata should follow L. dorsalis.

67. Lema fulvo-marginata.

Fulvous; labrum black; thorax subquadrate, sometimes punctured on the disc; elytra with a deep basal

depression, metallic blue or greenish, the extreme lateral and apical margins fulvous; legs entirely fulvous.

Length 13 line.

3. Head slightly constricted behind the eyes, the space surrounding the latter remotely punctured and sparsely

pubescent; labrum piceous; antenne nearly as long as the body, the basal joints fulvous, the others

slightly darker, the second to the fourth joints gradually increasing in length, the rest still more elongate

and equal; thorax subquadrate, the sides but very moderately constricted, the anterior angles without

tubercles, the basal sulcation distinct but not very deep, the surface with a double row of punctures on the

middle of the disc and a few punctures near the anterior angles; scutellum fulvous; elytra subdepressed,

with a short but deep impression below the base near the suture, strongly and not very closely punctured

anteriorly, much more finely posteriorly, the interstices costate near the apex, the surface of a metallic

greenish-blue colour, the lateral margin narrowly fulvous, this colour generally extending to the space

between the interrupted ninth row of punctures and to the apex ; underside and legs fulvous; the posterior

femora extending to the apex of the abdomen.

Hab. Muxico, Teapa in Tabasco (H. H. Smith).

The typical form of L. fulvo-marginata is well distinguished from the numerous small

species with metallic blue elytra by the narrow fulvous margin of the latter, this colour

being, however, in some specimens confined to the apex. Inthe female the antenne and

the posterior femora are shorter than in the male. The intermediate joints of the

antenne are more or less stained with fuscous, and sometimes the anterior tarsi and the

apices of the tibiz also.

CRIOCERIS.

Crioceris viridis (p. 15).

To the locality given, add:—Mexico, Almolonga, Jalapa (Hége), Orizaba (Godman),

Cordova (Sallé); Guatema.a, Sabo in Vera Paz (Champion).

There is a small, more or less distinct, fovea visible at the sides and near the middle

of the elytra in all specimens; of this Lacordaire makes no mention.

Crioceris nitida (p. 15).

To the locality given, add :—Guatema.a, Cerro Zunil (Champion).

Lacordaire places C. nitida amongst those species in which the prosternum is narrow

but distinct, which is the case in the Guatemalan examples. The latter are much

more shining than C. viridis, and are also more robust and generally larger; the thorax,

instead of having fine transverse ridges, is sparingly and finely punctured; and the

elytra are finely punctate-striate, and have (as in C. viridis) a distinct lateral fovea,

and the interstices are elevated at the apex. There appear to be several very closely

allied metallic green Central-American species which are not easy to separate. I have

not seen any Mexican specimens of C. nitida. |

CRIOCERIS. 45

Crioceris alternans (p. 15).

Crioceris costulata, Lac. huj. op. p. 15.

To the locality Mexico, add :—Queretaro (Dr. Palmer), Oaxaca, Yolotepec (Sallé).

An examination of a series of specimens subsequently received has proved to me

that C. costulata is the female of C. alternans, Lac. The differences pointed out by

Lacordaire are only sexual—thus in the male the punctuation of the elytra is closer

and more or less confluent, while the raised coste are less distinct than in the female ;

the posterior femora are, as usual, shorter in the female; and the abdominal tufts

of hairs are nearly always present in the males of the Central-American species of

Crioceris. The punctuation of the elytra in the present species is subject to a good

deal of variation, and in one specimen (a female) the coste are very strongly raised and

smooth. In all other respects the two insects treated by Lacordaire as distinct are

similar. -

Crioceris smaragdina (p. 15).

The specimens from Zapote referred to C. smaragdina belong, I think, to the following

closely-allied species. I have not seen any specimens which I can satisfactorily refer

to Lacordaire’s species.

8 (a). Crioceris curvipes.

Metallic green; the seven terminal joints of the antenne dark blue; thorax finely transversely strigose ;

elytra very finely semipunctate-striate, the interstices finely rugose at the sides ; femora very robust, the

anterior and posterior tibiz curved.

Length 3-44 lines.

Head with a few fine punctures, and a deep longitudinal median groove, the space round the eyes strongly

rugose; antennz more than half the length of the body; the first four joints metallic green, the others

dark blue ; thorax slightly longer than broad in the male, the sides scarcely constricted, the surface trans-

versely strigose throughout; scutellum finely punctured; elytra with a very shallow depression below the

base and a more or less distinct lateral fovea, the surface very finely and rather indistinctly punctate-

striate, with two rows of deeper punctures extending from the shoulder obliquely inwards, the sides

irregularly rugose towards the apex, the apical interstices not raised; femora short and swollen, the

tibiz in the male (and to a less extent in the female) distinctly curved; abdominal segments in the male

furnished with small tufts of whitish hairs at the sides.

Hab. Guatemaua, Cerro Zunil, Zapote (Champion).

C. curvipes may at once be separated from C. nitida and C. smaragdina by the tibie

being distinctly curved, in connection with the finely rugose sides of the elytra; it also

differs from C. smaragdina by the strigz of the thorax. The prosternum is very narrow,

but just visible ; the femora in the female insect are less robust, and the tibia are not

quite so much (though distinctly) curved.

8 (z). Crioceris nitidicollis.

Metallic green; thorax transverse, nearly impunctate, shining; elytra very finely and almost regularly pune-

46 PHYTOPHAGA.—SUPPLEMENT.

tured, the interstices not costate at the apex ; femora robust and incrassate, the intermediate and posterior

_ tibiee strongly curved.

Length 4 lines.

Hab. Mexico, Tapachula in Chiapas (Hége); GuatemMaLa, Zapote (Champion).

Although there are but two specimens of this species, I am obliged to separate them

from C. curvipes. They resemble the latter in the incrassate femora and curved tibie,

but differ in the almost impunctate and smooth thorax, and in the punctuation of ©

the elytra. The head in C. nitidicollis is rather closely punctured on each side; the —

antenne are coloured as in the allied species, but they have the third and fourth

joints short and equal (in C. curvipes the fourth joint is longer than the third, and

both are more slender); the thorax is scarcely constricted at the sides, and has several

transverse shallow depressions (the transverse rugosities or strigee are entirely absent,

and very fine punctures are visible only under a strong lens); the elytra are rather

closely and finely punctured, the punctures here and there arranged in lines, and the

interstices are not costate, but at the extreme apex they are irregularly rugose; the

legs resemble those of C. curvipes ; and the prosternum is just visible.

The specimen from Tapachula seems to be a female with shorter posterior femora ;

it has the thorax rather more distinctly punctured, but resembles in other respects the

Guatemalan insect.

8 (c). Crioceris championi.

Metallic green ; antenne dark blue; thorax short, almost imperceptibly wrinkled ; elytra distinctly depressed

below the base, each with a deep lateral fovea, the surface extremely finely punctured, the punctuation

semi-regular ; femora short, the tibie slightly curved.

Length 4-5 lines.

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

It will only be necessary to point out the differences between this and the preceding

closely allied species. C. championi is of the same brilliant metallic green colour, but

differs thus:—The thorax is very short and extremely finely wrinkled (the wrinkling

only visible under a strong lens); the elytra have a distinct depression below the base

(which is not visible in the allied species), the lateral fovea is deep and distinct, the

punctuation is very fine and scarcely arranged in rows, and the interstices are flat,

without coste or rugosities, but with traces of pubescence; and, lastly, the femora are

short and but slightly thickened, and the posterior tibie are scarcely curved. The

prosternum is invisible between the coxe. The male of C. curvipes has strongly

incrassate and longer posterior femora; in the corresponding sex of C. championi the

femora do not extend beyond the second abdominal segment.- The abdomen in the

Jatter has small white tufts,

Crioceris gemmans (p. 16).

To the locality Mexico, add:—San Andres, Cordova, Orizaba, Playa Vicente, Sante-

comapan (Sallé), Atoyac in Vera Cruz (H. H. Smith).

CRIOCERIS. AT

Crioceris nullicedo (p. 16).

To the localities given, add :—Mexico, Sacatepec (Sallé), Tapachula (Hége) ; GuaTE-

MALA, Cerro Zunil, Purula, Senahu, San Gerdnimo (Champion).

As an aid to the separation of this species from C. gemmans, I may add that, in

addition to the absence of the cupreous middle portion of the head, and the spot on the

thorax and shoulder, the first cupreous band of the elytra is in nearly every instance

obliquely shaped, the corresponding broader band in C. gemmans being always perfectly

‘straight. The variety callizona, Clark, was also obtained in several of the above-

mentioned localities.

Crioceris intermedia (p. 16).

To the localities given, add :—PanaMa, Volcan de Chiriqui (Champion).

This species is rather broader and more robust in appearance than C. nullicedo,

and differs in the broad cupreous elytral bands, these being as broad as in C. gemmans.

The last-mentioned character and the partly fulvous and partly metallic abdomen is the

only difference between C. nullicedo and C. intermedia; it is therefore possible that

the latter is but a local variety of C. nullicedo.

11 (a). Crioceris flohri. (Tab. XXXVI. fig. 1.)

Metallic cupreous ; the sides of the head and the antenne metallic green ; thorax finely rugose, metallic green,

the sides cupreous; elytra green, finely punctate-striate and pubescent, the basal margin and the

shoulders reddish-cupreous.

Length 5-6 lines.

Head metallic green at the sides, the middle reddish-cupreous and with a deep longitudinal groove, distinctly

punctured, the space surrounding the eyes strongly rugose and purplish in colour, the epistome cupreous ;

labrum and palpi metallic green; antenne more than half the length of the body, the four basal joints

bright metallic green, the following joints bluish and more opaque; thorax transverse, nearly twice as

broad as long, the sides slightly constricted, the surface with some irregular depressions, finely and closely

punctured and sparingly pubescent, the disc metallic green, the anterior angles reddish-cupreous ;

scutellum green or cupreous; elytra convex, without any trace of a basal depression, finely punctate-

striate and still more finely and very closely punctured on the rest of the surface, clothed with fine

whitish pubescence, metallic green, the extreme base and the shoulders reddish-cupreous; below and the

legs cupreous, mixed with metallic green or blue, the sides of the abdominal segments fulvous or

flavous.

Hab. Mexico, Almolonga (Flohr); Guatemata, Purula (Champion).

Of this large and beautiful species Mr. Flohr has kindly sent me a single specimen ;

another was obtained by Mr. Champion. The latter, probably a female, is larger, and

has the punctured strie of the elytra scarcely visible, and the rest of the punctuation

extremely fine, but agrees in all other respects with the Mexican insect.

The Guatemalan example is figured.

Crioceris scabrosa (p. 17).

To the locality Mexico, add :—Yolotepec (Sallé).

14. Crioceris rugipennis. (Tab. XXXVI. fig. 2.)

Obscure zeneous, the head, antenne, and thorax black ; head rugosely punctured ; thorax transversely strigose ;

elytra each with four rows of black irregular rugosities, closely rugose-punctate, the punctures obscure

cupreous or eneous.

Length 4 lines.

Head rather elongate, rugose throughout, the interior of the rugosities furnished with very short silvery pubes-

cence; antenne extending a little beyond the base of the elytra, the terminal joints widened, the basal

joint subquadrate, the third and fourth joints equal and more slender than the following ones ; thorax

scarcely longer than broad, subconical, the sides not, or scarcely, constricted, the surface impressed with

fine transverse ruge, the middle of the disc with a longitudinal groove, the groove clothed with very

short silvery hairs ; scutellum clothed with whitish pubescence; elytra without any basal depression or

elevation, their entire surface impressed with pale reddish metallic punctures, the punctures clothed with

very short silvery pubescence within (only visible in a certain light) and interrupted by four longitudinal

rows of smooth black irregular elevations which are here and there transversely connected ; underside

and legs obscure metallic cupreous, clothed with very short silvery hairs.

Hab. Mexico, Almolonga (Flohr).

It is difficult to convey a correct idea of the sculpture of the elytra, it resembling to

a certain extent that of certain species of Curculionide ; to the naked eye the surface

is dull, of a reddish-white colour, interrupted by black stripes; under a lens the pale

metallic cupreous colour of the punctuation is at once to be seen. C. rugipennis is

somewhat allied to C. scabrosa, Baly.

A single specimen of this interesting new species has been kindly sent me by

Mr. Flohr.

Hab. Guatemata 1, Totonicapam 7000 to 10,000 feet (Champion).

This species is distinguished by the curious sculpture of the elytra, the posterior portion

being striate, and the anterior portion irregularly punctured, A very large number of

specimens were obtained by Mr. Champion in the Los Altos region of Guatemala.

CRIOCERIS.—MEGASCELIS. 49

Of this well-known species, which has been recorded not only from Europe but

from India and Brazil, two specimens have been received from Mr. Forrer: thus the

geographical range of C. merdigera seems to be one of the most extended amongst the

Coleoptera. It is impossible to say, however, whether the species is indigenous in all

these different parts of the World, or has been introduced accidentally. The com-

plicated synonymy of C. merdigera is given in full in Lacordaire’s monograph, as well

as in Gemminger and Harold’s catalogue. It is probable that the species will eventually

be found in North America.

MEGASCELIS (p. 17).

It has already been remarked by Lacordaire in his excellent monograph, and’ by

myself in speaking of the genus, that the determination of the numerous species of

Megascelis is extremely difficult; and that the best descriptions cannot always convey

a correct idea of the minute specific differences which separate so many variable and

closely allied forms. A comparison with the types can only settle the many doubts

which arise in the determination of these insects. I have fortunately been enabled to

examine many of Lacordaire’s types, those of Baly, Bates, and Clark, contained in the

British Museum, but only a few of the species from Central America have I been able

to identify with these. In many cases I have been obliged to found species upon

single specimens, often females, and it is therefore quite possible that eventually some

of those described here may prove to be synonymous with others of Lacordaire. There

is scarcely a single structural character to be pointed out which can be relied upon in

the separation of the species; the elytra are very similarly sculptured in all, their

colour variable, and the same is the case with the underside; and the differences in the

shape and sculpture of the thorax, which seem to be of a more constant kind, are often

so slight that it is impossible to convey a proper description by words. Under these

circumstances it will always be more satisfactory to treat the different species according

to their localities, or, in other words, to monograph those of a certain region.

When the earlier part of this work was published I had not a single representative

of the genus from either Mexico or the State of Panama before me, and the additional

species are in consequence very numerous.

Megascelis dilecta (p. 17).

This species seems only to differ from the following in the more narrow and regularly-

shaped sutural stripe, and in the darker green upper surface. Had Clark read

Lacordaire’s description of VM. suturalis the very close affinity of M. dilecta with it

could not have escaped him; instead of that he compares M. dilecta with M. amabilis

(of which a type specimen is contained in the British Museum), with which it has no

affinity whatever, and the type, which Clark could never have seen.

Hab. Mexico !, Toxpam, Cordova, Playa Vicente (Sallé), Cerro de Plumas (Hoge),

Teapa in Tabasco (H. H. Smith).

This species was unfortunately overlooked by me in the earlier part of this work,

and will find its place close to WM. dilecta. It differs from the latter in the elytra being

rounded at the apex, and in the fuscous sutural band (instead of being widened poste-

riorly) being widest anteriorly and gradually narrowed behind. The general colour of

the upper surface of MM. suturalis isa pale green, with the exception of the more or

less broad fuscous sutural stripe; this stripe is described by Lacordaire as “ nigricante,”

but specimens with so dark a stripe I have not seen.

A good many specimens have lately been received from Teapa ; these vary con-

siderably in size, but only a little in colour. In all the head is strongly rugose and

the suture narrowly fuscous; the sutural stripe, however, is not (as usual) widened

anteriorly, but is of equal width throughout or slightly widened towards the apex.

1 (s). Megascelis minuta.

Narrowly elongate, pale testaceous, above with a metallic green tint; terminal joints of the antenne black ;

head distinctly punctured ; thorax not longer than broad, closely punctured ; elytra sparingly pubescent,

strongly punctured, the interstices transversely rugose. .

Length 14 line.

Head pale metallic green, distinctly and rather closely punctured, the epistome not separated from the face ;

mandibles black; antenne two thirds the length of the body, black, the basal three or four joints testa-

ceous; thorax not longer than broad, rather distinctly narrowed at the base, the sides rounded and

widened, the surface with a shallow but distinct transverse groove across the disc, the latter closely

impressed with distinct punctures which are a little larger than those on the head, the interspaces only

very slightly rugose near the base; scutellum truncate at the apex, distinctly punctured; elytra narrowly

parallel, pale fulvous with a more or less distinct metallic green gloss which is more intense at the

shoulders, the latter prominent and acute, the surface strongly punctate-striate, the interstices trans-

versely rugose and sparingly covered with short pubescence; underside pale piceous or testaceous; legs

entirely testaceous.

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

This small species is closely allied to WU. suturalis, Lac., but differs apparently in the

very pale colour of the upper parts and in the sculpture of the head; the latter (instead

of being closely rugose) is impressed with single punctures, the interspaces being smooth.

M. minuta may be known from I. viridipallens, Clark, by the much smaller size and

several other differences, which will be seen by a comparison of the respective descrip-

tions. WM. gracilis, Lac., seems to be another close ally of MZ. minuta.

(Champion).—Cotompta 1,

Numerous specimens from the above localities agree so well with the description of

this species that I must refer them to it. The elytra in all of them have their extreme

apex subtruncate, and their inner angle produced into a small and more or less distinct

tooth (Lacordaire says nothing of this tooth, which would place the insect in his first

division), and the suture accompanied by a pale fuscous band which gradually widens

posteriorly ; this band is similar in shape in all the specimens before me, and it seems

to distinguish Jf. lacertina from M. suturalis, Lac., in which the band is widened

anteriorly. | |

Megascelis affinis (p. 18).

To the Guatemalan locality given, add :—Senahu in Vera Paz (Champion).

Several more specimens of this species are now before me. In these the underside

varies in colour from metallic blue to testaceous ; the upperside is very depressed and of

a uniform metallic dark green or eneous; and the size varies from two to four lines.

Our insect agrees so well with Lacordaire’s description of MW. affinis that I have not

hesitated to identify it with that species, though in the present genus only a comparison

with the type can remove all doubt. 7

4. Megascelis vittatipennis.

Megascelis vittata, huj. op. p. 18 (nec Fabr.).

Fulvous or piceous; above metallic green, clothed with yellow pubescence; head and thorax finely rugose ;

thorax with a raised central line; elytra opaque, metallic green, with a broad subsutural fuscous or

purplish stripe.

Length 2-2; lines.

Head metallic green, finely rugose, clothed with golden pubescence at the base, the epistome more coarsely

punctured ; antenne nearly as long as the body, fuscous, the four or five basal joints testaceous ; thorax

scarcely longer than broad, slightly constricted at the base, transversely grooved at the middle, finely

rugose, and clothed with golden pubescence, the disc with a raised longitudinal line in the middle, this line

being furnished at some distance from the base with a small tubercle ; elytra with the usual transversely-

shaped punctures, the suture clothed with golden pubescence, and accompanied by a broad longitudinal

fuscous or purplish band, followed by an equally broad metallic band occupying the rest of the sides ; legs

testaceous.

Hab. GuatemMata, San Isidro, Zapote (Champion).

M. vittatipennis differs from J. vittata (Fabr.), in having the thorax much longer than

broad and of more cylindrical shape, and the elytra, as well as their bands, more metallic.

The present insect is of a rather opaque colour, caused by the golden pubescence; in all

specimens the small tubercle placed on the dorsal carina of the thorax is present. This

species was erroneously identified as J. vittata in the earlier part of this work.

52 PHYTOPHAGA.—SUPPLEMENT.

Megascelis purpureicollis (p. 18).

To the locality given, add:—Guatemaa, Panzos in Vera Paz (Champton); Panama,

Caldera, Tole (Champion).

The example from which the original description was drawn is a female of large size

(4 lines) ; amongst the specimens since received there are several males, which are, as

usual, much smaller. IM. purpureicollis may be known from ‘most of its congeners by

the elytra being of a dull, opaque, obscure greenish colour, with the suture and a very

narrow lateral stripe (composed of closely arranged pubescence) yellowish ; these stripes

are not always distinct, and can only be seen in certain lights, although when present

they are visible to the naked eye. The head and thorax are generally purplish,

occasionally greenish, and covered with rather long but fine golden pubescence. The

underside in all the specimens is dark fulvous with a more or less distinct metallic

gloss, and clothed with short silvery pubescence. There are few species of the genus

having the dull appearance of the present insect, this being partly due to the short

yellow pubescence which covers the elytra; the last-named character and the reddish

colour of the head and thorax will assist in the recognition of M/. purpureicollis.

Megascelis stratiotica (p. 19).

The specimen from Capetillo which I doubtfully referred to this species belongs to

the following. WV. stratiotica must accordingly be erased from our list.

7. Megascelis spinipes.

Megascelis stratiotica, huj. op. p. 19 (nec Lacord.).

Obscure dark metallic green; below dark fulvous or piceous; the basal joints of the antenne and the legs

testaceous ; thorax cylindrical, elongate, rugosely punctured, with a smooth central ridge; elytra trans-

versely punctured, with some longitudinal depressions ; posterior femora of the male with a long spine.

Length 12-23 lines.

Head rugosely punctured ; eyes notched; the epistome separated from the face by an indistinct groove, and

more coarsely punctured; labrum fulvous; antenne fuscous, the basal four joints testaceous ; thorax

longer than broad, cylindrical, narrowed from the middle to the base, the disc with a raised more or less

distinct central ridge, the surface finely and rugosely punctured and clothed with fine golden pubescence ;

elytra rather flattened, with a more or less distinct short longitudinal depression near the scutellum and

another along the suture, the surface of an obscure dark metallic green colour, the lateral margin dark

fulvous or purplish, clothed (like the thorax) with golden pubescence, the punctures close and of transverse

shape, the interstices slightly raised longitudinally ; the underside piceous or dark fulvous, clothed with

silvery pubescence, the breast more or less metallic greenish ; legs testaceous; the posterior femora of the

male strongly curved, rather slender at the base, and armed near the apex with a long stout spine.

Hab. Mexico, Tapachula in Chiapas (Hége); Guaremana, Cubilguitz, El Tumbador,

San Isidro, Capetillo (Champion).

So far as I am aware, there is only one species described by Lacordaire the male of

which, like that of the present one, is distinguished by having a long femoral spine.

From that insect (MU. stratiotica) M. spinipes differs in being of a sombre and scarcely

metallic green colour, the lateral margin alone being brownish or purplish ; the thorax

MEGASCELIS. 538

(which in M. stratiotica is described as being finely transversely wrinkled and without

punctures) is very distinctly and closely punctate ; and the two longitudinal depressions

on the elytra are rather distinct in the male, the one along the suture being bounded

outwardly by a perceptible elevation of the third elytral costa. In two female specimens

obtained at Cubilguitz the whole underside is metallic green; these specimens are

larger, but do not seem to differ in any other way. J. spinipes is no doubt closely

allied to M. stratiotica, but I cannot identify it with that species on account of the

above-mentioned differences.

9. Megascelis curta.

Subdepressed, slightly widened posteriorly, below obscure greenish-sneous or piceous, above bright green, the

first four joints of the antenne and the legs testaceous; head and thorax rugosely punctured; elytra

transversely punctate.

Var. The legs more or less metallic green.

Length 13-1 line.

Head closely rugose-punctate ; the eyes broadly but feebly notched; epistome separated from the face by a

triangular not very distinct groove, metallic green, very shining, deeply but not very closely punctured ;

palpi pale fulvous, the apical joint fuscous ; antennz about two thirds the length of the body, fuscous,

the lower four joints testaceous ; thorax scarcely longer than broad, slightly widened at the middle, with

an indistinct transverse depression at the sides, the surface closely and deeply punctured, without

longitudinal ridge, and very sparingly clothed with short silvery hairs; scutellum subquadrate; elytra

more or less distinctly widened posteriorly, impressed throughout with transversely-shaped punctures, the

interspaces scarcely raised, and sparsely clothed with short silvery hairs; underside dark greenish-

piceous, more or less metallic, the abdomen paler and densely covered with silvery pubescence; legs

testaceous or more or less metallic green.

Hab. Mexico, Cerro de Plumas (Hége), Juquila (Salié).

M. curta is comparatively easy to recognize amongst its numerous congeners if the

following details are considered :—lIn its general shape (instead of being narrow and

parallel as is usually the case) it is slightly widened behind ; the colour of the upper

surface is a uniform bright green, without any tint of fulvous or testaceous, and not

obscured by a fine pale pubescence ; the underside is obscure piceous with a metallic

gloss; and the eyesare largely (not triangularly) notched. MM. curta seems to be closely

allied to WM. smaragdula, from which it differs in the coarsely punctured epistome, and

the colour of the underside.

10. Megascelis mexicana. (Tab. XXXVI. fig. 4.)

Fulvous; the antenne (the apical joints excepted), knees, tibie, and tarsi black; thorax subquadrate,

rugosely punctured ; elytra purplish or bluish, finely pubescent, strongly punctured, the interstices longitu-

dinally costate.

Var, The abdomen and legs entirely black.

Length 3-4 lines.

Head rugosely punctured, fulvous; the space below the insertion of the antenne rather deeply excavated on

each side and very strongly rugose; the mandibles and the terminal joint of the palpi fuscous; eyes

broadly but not deeply notched ; antennz about half the length of the body, black, the apical two joints

more or less distinctly testaceous ; thorax not longer than broad, slightly constricted at the base, fulvous,

closely punctured at the sides and at the base, more sparingly so on the middle of the disc, the latter

very sparsely pubescent; scutellum truncate at the apex, finely punctured, fulvous; elytra depressed, the

54. . PHYTOPHAGA.—SUPPLEMENT.

apex rounded, very sparingly clothed with yellowish pubescence, closely and strongly punctate-striate,

the punctures often of transverse shape, the interstices longitudinally (but not strongly) raised ; underside

fulvous ; the knees, tibiee, and tarsi black ; the posterior femora in the male extending to the apex of the

abdomen.

Hab. Mexico, Cordova, Toxpam (Sailé), Oaxaca (Hoge).

This is one of the largest species of Megascelis; it may be known by the uniform

dark purplish or bluish colour of the elytra, the fulvous underside without metallic

gloss, and the black knees, tibie, and tarsi. The scutellum in some specimens is

metallic green instead of fulvous. The black basal joints of the antenne will further

assist in the recognition of WM. mexicana.

The variety (from Cordova) differs only in the colour of the abdomen and legs.

11. Megascelis sallzi.

Obscure fulvous ; head and thorax darker fulvous with a purplish gloss, finely rugose ; elytra obscure purplish,

the shoulders and the sides metallic blue or greenish ; legs testaceous.

Var. Elytra obscure fulvous with a greenish tint.

Length 14 line.

Head rugosely punctured throughout; the epistome not separated by a groove, more strongly punctured ;

antenne two thirds the length of the body, fuscous, the basal four or five joints testaceous; thorax

slightly longer than broad, narrowed at the base, with an almost obsolete transverse depression across

the middle, the surface more strongly rugose-punctate than the head, with a slight indication of a dorsal

carina, fulvous with a purplish gloss (like that of the head); elytra clothed with very short silvery

pubescence, opaque, the middle of the dise purplish, the shoulders and sides metallic bluish.

Hab. Mexico, Playa Vicente, Orizaba (Sailé).

M. salle is of rather broad and robust shape and of very sombre and dull appearance.

Some specimens differ from the type in having almost the entire upper surface brownish,

with a slight metallic green tint. The dorsal carina in most specimens shows a raised

longitudinal tubercle near the base. The elytra have the interstices longitudinally

raised, and the spaces between impressed with transversely shaped rugosities; their

pubescence is very short, in the type whitish, in the varieties more fulvous. The

underside varies in colour from piceous to testaceous. It is difficult to fix the limit of

this species; but the dull opaque colour of the upper parts will perhaps best assist in

the recognition of WM. sallai.

12. Megascelis robusta.

Broadly parallel, pale fulvous, the breast obscure greenish ; above obscure metallic green ; head and thorax

finely rugose, clothed with fulvous pubescence ; elytra transversely punctured, the interstices longitudinally

costate.

Length 3 lines.

Head very finely rugose throughout, with a tubercle between the antenneg; eyes distinctly emarginate ;

antenne: fuscous, the base of each joint testaceous, the three or four basal joints entirely of that colour ;

thorax scarcely longer than broad, distinctly widened at the middle, with an obsolete transverse depres-

sion at the centre of the disc, the surface very finely rugose (like that of the head) and sparingly clothed

with fulvous pubescence ; scutellum finely punctured ; elytra broad, robust, entirely covered with trans-

verse rugosities, the interstices longitudinally raised, the colour a dull metallic green obscured by the

MEGASCELIS. 55

fulvous pubescence ; underside clothed with fine silvery pubescence, the abdomen and legs fulvous, the

breast with a tinge of pale metallic green; claws piceous.

Hab. Mexico, Panistlahuaca (Sallé).

Of this rather large-sized Megascelis there are two female specimens before me which

I cannot satisfactorily identify with any described species of similar size. The very

finely rugose head and thorax, the dull colour of the upper parts, and the costate

interstices of the elytra will assist in the determination of I. robusta.

13. Megascelis tibialis,

Metallic blue ; above obscure dark green or purplish; the antenne, tibie, and tarsi black.

Length 2~23 lines.

Head metallic green or blue, deeply and closely punctured ; the epistome separated by a more or less distinct

triangular groove, very coarsely rugose-punctate ; labrum testaceous; palpi fulvous; antenne almost

entirely black, the basal joints sometimes fulvous below ; thorax about one half longer than broad, distinctly

narrowed below the middle, deeply and closely punctured, the interspaces towards the base transversely

rugose, the surface clothed with thin fulvous pubescence, and without central ridge; elytra dull greenish

or purplish, clothed with whitish pubescence, deeply and closely punctured, the interstices transversely

wrinkled ; underside metallic blue or green; the femora fulvous, the knees, tibiee, and tarsi black.

Hab. Mexico, Toxpam, Cordova, Orizaba (Sallé), Oaxaca. (Hoge).

From all the species of the genus, with the exception of two or three, UM. tibialis

may be known by the metallic underside in connection with the dull coppery or

greenish colour of the upper surface. From the Brazilian I. ewilis and MW. anguina,

Lac., the present insect is separated by the black colour of the knees, tibie, and tarsi.

The four specimens before me show no difference in the above particulars.

14. Megascelis collaris.

Fulvous ; the breast black or piceous; head and thorax very finely punctured, the latter deeply transversely

grooved ; elytra metallic blue, the suture narrowly purplish.

Var. The elytral suture narrowly fulvous.

Length 2 lines.

Hab. GuatEMaLa, Zapote (Champion); NicaRracva, Chontales (Janson); PANAMA,

Bugaba, Caldera in Chiriqui (Champion). 7

I can only compare MV. collaris to M. amabilis or M. frenata, Lac., of Colombia,

with which it agrees in size and, partly, in colour. In the present species the head and

thorax are fulvous, with a pale metallic green tint; the head is very finely and

sparingly punctured (in which J. collaris differs from most other known species) ; the

antenne are black, with two or three of the basal joints fulvous; the thorax is of the

same colour as the head, rather closely and distinctly punctured at the sides, less closely

in front, without any transverse rugosities, the anterior portion being rather strongly

swollen, and bounded behind by a deep transverse depression (in If. amabdilis the thorax

is of similar colour and punctuation, but the anterior portion is far less strongly deve-

loped, and the groove is shallower); the elytra are impressed with the usual transverse

56 PHYTOPHAGA.—SUPPLEMENT.

rugosities, and punctured on the interstices, sparingly clothed with fulvous pubescence,

and generally of a dark metallic-blue colour, with the sutural and lateral margins

narrowly purplish. In some specimens all the colours are paler, but perfectly recog-

nizable. Usually the underside, as well as the legs, is fulvous, and the breast nearly

black ; in one or two examples, however, the underside is altogether darker. M. frenata

has the elytra similarly coloured, except that the suture is more broadly purplish; and

the thorax much longer and with a less distinct transverse groove. The variety only

differs in colour ; it is from Chontales.

15. Megascelis championi.

Pale testaceous ; above pale metallic green; head remotely, the thorax more closely, punctured ; the latter

strongly narrowed posteriorly, and with a distinct transverse groove; elytra sparingly pubescent, the

suture pale testaceous, the basal and lateral margins purplish or blue.

Length 14-2 lines.

Hab. Guarema.a, Zapote (Champion) ; Panama, Caldera in Chiriqui (Champion).

The general colour of the upper surface is similar to that of IZ. quadrisignata, except

that there are no spots, a pale metallic green covering a testaceous ground-colour ; the

head is remotely punctured, and the punctures are much deeper anteriorly than at the

base (the distant punctuation is therefore one of the characters by which M/. championi

may be known from most of its allies); the thorax is not longer than broad, more

closely punctured than the head, almost without transverse wrinkles, the surface of the

same testaceous colour as the head, with a similar pale green metallic gloss, and with

a distinct transverse groove; the scutellum is also of the same colour as the thorax ;

the elytra are of a brighter metallic green, the basal and the lateral margins more or

less distinctly blue or purplish and the suture pale fulvous or testaceous, and the punctua-

tion is distinct and less interrupted by transverse strigee than usual ; and the antenne are

black, with pale basal and (in one specimen) apical joints. MU. championi resembles in

the shape, colour, and punctuation of the thorax MV. collaris ; and it is quite possible

that the former is only a pale variety of the last-named species. I have, however, three

specimens before me which agree with each other in the colour of the elytra (it is dark

blue in I. collaris); and in the absence of intermediate specimens I cannot look upon

them as varieties.

16. Megascelis quadrisignata.

Testaceous or fulvous; above pale metallic greenish ; thorax closely punctured, with a raised longitudinal

central line; elytra covered with very short pubescence, each with a spot at the base and another below

the middle purplish-blue.

Length 14 line. ,

Head not very closely but distinctly punctured, light metallic green ; antenne black, the four basal joints

testaceous ; thorax not longer than broad, widened at the middle, with a transverse central depression,

closely punctured, without transverse strige, the disc with a central longitudinal ridge, the punctures

larger anteriorly than at the base; scutellum deeply punctured ; elytra with the usual transverse strige,

MEGASCELIS.—MASTOSTETHUS. 57

clothed with short fulvous pubescence, testaceous with a pale metallic green gloss, each with a sub-

quadrate purplish or bluish spot at the base and a smaller one below the middle; underside and legs

fulvous.

Hab. Panama, Bugaba, Caldera in Chiriqui (Champion).

This pretty little species, of which there are two specimens before me, greatly

resembles in the elytral markings M. quadrimaculata, Bates, from the Amazon region.

The latter, however, differs from the Panama insect in the nearly impunctate head

and in its generally larger size; it also has the thorax much less closely and finely

punctured.

MASTOSTETHUS (p. 19).

Mastostethus balteatus (p. 19).

Mastostethus nigrocinctus, huj. op. p. 20.

Cubilguitz, Purula and Chacoj in Vera Paz, Las Mercedes (Champion); Costa Rica

(Van Patten); Panama, Bugaba, Volcan de Chiriqui (Champion).

After comparing carefully more than fifty specimens I can only come to the con-

clusion that If. nigrocinctus is a variety of M. balteatus. The two insects in question

have been separated merely by slight differences in coloration, which cannot be con-

sidered a character of distinction, as the many varieties enumerated by Lacordaire of

M. nigrocinctus prove. M. balteatus is most variable, and specimens occur which are,

with the exception of the underside, entirely fulvous. The punctuation of the elytra

does not furnish a distinctive character between the two so-called species.

Mastostethus cingulatus (p. 20).

M. cingulatus is undoubtedly nothing but an immature form of either M. balteatus

or WM. bilobus ; I have several specimens agreeing with the type and also intermediate

degrees in coloration before me, and as no structural character has been pointed out by

Lacordaire, and the species is a most variable one in regard to colour, I do not think it

any advantage to retain it as distinct.

Mastostethus bilobus (p. 20).

To the localities given, add :—GuatEMaLA, Yzabal (Sal/é), Panzos, Teleman, and San

Juan in Vera Paz, El Reposo (Champion) ; Panama (Boucard), San Lorenzo (Champion).

It seems to me also doubtful whether UW. bilobus should be looked upon as anything

but a variety of WZ. balteatus, from which it does not differ except in the colour of the

thorax and underside. There are several specimens before me which show intermediate

stages of variation in this respect, and scarcely two are exactly alike ; structural differ-

58 PHYTOPHAGA.—SUPPLEMENT.

ences I am unable to find. In the Panama examples the elytral black spots are

enlarged into elongate triangular patches occupying the principal portion of the disc ;

in these examples the thorax is almost entirely black, with the exception of the anterior

angles and the posterior margin, and the sides of the breast and the legs are entirely

black. All the Panama specimens are thus marked, and if I had not intermediate forms

from other localities before me I should have looked upon them as a distinct species.

Examples from Panzos have entirely fulvous antenne and legs.

Mastostethus duplocinctus (p. 20).

To the locality Mexico, add :—Cordova (Saldé).

Mastostethus tricinctus (p. 20).

To the localities given, add:—Guaremata, Zapote (Champion) ; Panama, Volcan de

Chiriqui (Champion), Colon (Boucard).

Mastostethus salvini (p. 21). (Tab. XXXVI. fig. 5, var.)

To the locality given, add :—Mexico, Atoyac in Vera Cruz (H. H. Smith) ; Panama

Bugaba, Volcan de Chiriqui (Champion).

The specimens since obtained in the State of Panama differ from the type in being

smaller in size, and in having the black portion of the elytra reduced, so that the

testaceous ground-colour occupies a greater space ; the elytra may therefore be described

as testaceous, with a subquadrate black patch at the base, not extending to the suture,

and a transverse band below the middle extending to either margin. MV. salvini differs

from UW. rogersi in the less narrow and attenuate general shape, in the colour of the

head, and in the impunctate thorax. MU. duplocinctus, Clark, is a much broader insect,

and has the head, antennee, and legs black, and the elytral bands different in shape and

position. Lastly, MZ. salvint may be known from several allied species of somewhat

similar pattern by the testaceous apex of the elytra. An example from Bugaba is

figured.

8 (4). Mastostethus cordovensis. (Tab. XXXVI. fig. 7.)

Testaceous, a band on the head, the antenne, the disc of the thorax, the scutellum, and the legs, black;

elytra testaceous, a triangular spot at the base, and a broad transverse band at the middle, black ; sides of

the breast and of the abdominal segments black.

Length 4 lines.

Head fulvous, punctured near the eyes, the base and a central longitudinal band black; antenne entirely

black ; thorax narrowed in front, about one half broader than long, the sides nearly straight, the surface

impunctate, black, the sides narrowly fulvous; elytra rather strongly but not very closely punctured,

with a triangular black spot at the base, surrounding the shoulders, but not extending to the sides, and a

black band at the middle extending to the sides, the anterior edge of the latter straight, the posterior

edge strongly concave ; below testaceous, the parapleure and sides of the breast, and the sides of the

first abdominal segments, black.

Hab. Mexico, Cordova (Sallé).

MASTOSTETHUS. 59

The elytral pattern of WM. cordovensis agrees nearly with that of WU. salvini; but the

colour of the head, thorax, and legs and the shape of the elytral spots are different.

The three specimens obtained do not differ from each other, except in the broader

shape of the transverse elytral band in one example; the flavous or testaceous apical

portion of the elytra forms a large ovate spot. IU. duplocinctus has a similar elytral

pattern, but is a much broader insect ; it has the head entirely black, and the shape of

the elytral black band is quite different. From other somewhat similarly-coloured

species M/. cordovensis may be known by the flavous apex of the elytra; from M. rogerst

by the colour of the head, thorax, and legs; and from MW. chontalensis by the triangular

shape of the humeral spot, and the position and shape of the posterior band, also by

the different coloration of the underside and legs. MW. zonatus, Klug, from Brazil, is

another closely allied species; but in this the head has a transverse (not longitudinal)

black band, the elytral fascia is narrower and of different shape, and the colour of the

legs is not entirely black, but fulvous and black.

8 (s). Mastostethus gracilenta. (Tab. XXXVI. fig. 6.)

Testaceous, a transverse band on the head, the antenne, two spots on the thorax, the upper edge of the

anterior femora, the tibia, and the sides of the breast, black ; elytra very closely and strongly punctured,

testaceous, a narrow transverse band at the base, and a broad band at the middle, black.

Length 3 lines.

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

In coloration this species closely resembles MM. salvini and its allies, but it differs

from them all in the strong and close (almost rugose) punctuation of the elytra. The

head is black at the base and between the eyes, the black markings being connected

together in one of the specimens, and enclosing two small fulvous spots. The thorax

is rather broad, and entirely impunctate; and has two large subquadrate black spots

on each side, joined in one specimen at its base. The elytra are rather narrow and

somewhat convex, and have a slight depression below the base at the suture; the band

at the base is narrowed at the suture; the posterior band is broad, slightly curved, and

extends to the sides, leaving the apex largely flavous, its anterior edge is nearly even,

the posterior one slightly irregular. The femora are testaceous, the two anterior pairs

streaked with black above. The underside is flavous or testaceous, with a spot near

the anterior coxe, and the sides of the breast (more widely so in front) and of the

metasternum, black.

Mastostethus rubricollis (p. 21).

To the locality Mexico, add :—Toxpam, Cordova (Sallé), Jalapa (Hoge).

The thorax in all the specimens before me has either a black transverse band or two

more or less distinct spots on the middle of the disc.

Mastostethus vicinus (p. 22).

To the locality Mexico, add :—Toxpam (Sal/é).

A single specimen from the above locality agrees well with Lacordaire’s description

of this species. It has the antennz entirely black, and the elytral bands are slightly

different in shape from those of I. rubricollis. |

Mastostethus rogersi (p. 22).

To the locality given, add:—Mexico (coll. Jacoby).

Mastostethus chontalensis (p. 22).

To the locality given, add :—Panama, Bugaba (Champion).

The specimen since received from the State of Panama only differs from the

Nicaraguan type in its smaller size, and in the larger black basal band of the elytra,

the intermediate flavous band being thus reduced to half its size.

15 (a). Mastostethus femoratus, (Tab. XXXVL. fig. 8.)

Black, the sides of the thorax and the first abdominal segments flavous; elytra finely punctured, flavous, a

narrow transverse band at the base, a broader one at the middle, a spot near the apex, and the suture at

the same place, black.

¢. The posterior femora robust and triangularly widened at the apex, and the posterior and intermediate

tibie strongly curved.

Length 43 lines.

Of elongate, slightly convex and posteriorly narrowed shape; the head black, rather closely punctured between

the eyes, deeply transversely grooved below the insertion of the antenne; the anterior margin of the

clypeus and that of the labrum and the apical joint of the palpi fulvous; antennx black, the lower four

joints shining, the rest opaque, dilated from the fifth joint; thorax nearly twice as broad as long, the

posterior margin nearly straight, the anterior angles somewhat prominent and bounded by a groove

within, the surface black, impunctate, the lateral margins narrowly flavous, a small black spot imme-

diately below them ; scutellum black ; elytra finely and not closely punctured, the punctuation scarcely

visible near the apex, the black basal band narrow, not extending to the lateral margin, its posterior

margin uneven, the band at the middle broader, straight, and extending to the sides, the suture below

this band black, the black not extending to the apex, and slightly widened behind, and a roundish spot

at the sides near the apex, also black ; underside black, the first two abdominal segments flavous.

Hab. Guatemata, Purula (Champion).

M. femoratus almost exactly resembles in coloration WV. stalii, but is larger and more

23. Mastostethus modestus. (Tab. XXXVI. fig. 13.)

Black; the head punctured near the eyes; thorax with afew very fine punctures; elytra pale brownish,

sparingly pubescent and strongly punctured, the base and a sublateral longitudinal narrow stripe on each

black.

Length 44 lines.

Head black, rather strongly punctured near the eyes; the anterior margin of the clypeus and that of the

labrum fulvous; antenne scarcely extending to the base of the thorax, entirely black; thorax twice as

broad as long, the sides slightly rounded before the middle, a transverse groove near the anterior margin,

the latter rather closely punctured, the disc with a few very fine punctures; scutellum black, punctured,

and with some fulvous hairs ; elytra depressed, rather elongate and narrowed posteriorly, the basal margin

narrowly black, the black deeply indented in front of the shoulders, and connected with the narrow

longitudinal black stripe, this latter being placed close to the lateral margin, and abbreviated just before

the apex; underside and legs entirely black, clothed with fulvous pubescence.

Hab. Mextco (Sallé, ex coll. Sturm).

A single specimen, labelled “ Megalopus modestus,” is contained in the Sallé col-

lection.

24. Mastostethus panamensis. (Tab. XXXVI. figg. 9, 10.)

Depressed, narrowed posteriorly, flavous, the base of the head, the antenne, the disc of the thorax, and the

tibie, black ; elytra finely punctured, black, the basal margin obliquely flavous.

Var. Elytra with the apex, as well as the base, flavous.

Length 34-4 lines.

Head black to the insertion of the antennz, the lower portion flavous, the space near the eyes closely punc-

tured, the indented portion of the eyes obscure testaceous ; antenne black, the lower four joints shining,

the rest opaque and transversely flattened ; thorax with the sides straight, narrowed in front, the surface

with a few minute punctures, the sides flavous, the disc occupied by a transverse black band, which is

rather deeply indented at the sides; scutellum black ; elytra depressed, finely and rather closely pune-

tured, with an obsolete oblique depression below the base, black, the depression (in the shape of a narrow

transverse band) flavous ; underside and femora flavous, the tibiz black, the two anterior pairs strongly

curved, the tarsi black.

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

M. panamensis seems to be somewhat allied in coloration to the South-American

62 PHYTOPHAGA.—SUPPLEMENT.

M. curvipes (Fabr.), but differs in the colour of the antenne and in the shape and

position of the elytral markings. In the specimens which have the greater part of

the elytra and their apex black, the narrow fulvous basal margin is of a more oblique

shape than in those which have the apex to a greater or less extent flavous; in these

dark-coloured examples the anterior edge of the black portion is straighter.

25. Mastostethus imitans. (Tab. XXXVI. fig. 11.)

Flavous ; the base of the head, the antenne, a large spot on the thorax, the elytra (the basal margin excepted),

the apices of the tibie, and the tarsi, black.

Length 4 lines.

Hab. Panama, Bugaba (Champion).

M. imitans so exactly resembles the preceding species in coloration that it will only

be necessary to point out the differences:—The thorax in J. imitans is a little more

distinctly and closely punctured on the disc, and the sides of the black patch are but

slightly sinuate, not deeply dentate; the scutellum in three specimens is flavous (in

one it has a small black spot); and the elytra show no postbasal oblique depression—

they are black with a narrow, mesially widened, flavous basal margin, as in WM. pana-

mensis, and are also punctured as in that species, but the lateral margin is accompanied

by a narrow, smooth, impunctate space, bounded within by an impressed stria which

extends to the apex (this being altogether absent in the allied species); and the tibie,

instead of being black, have only their extreme apex of that colour. These characters

are constant and not sexual, as an examination has proved; in all other respects

M. imitans agrees with I. panamensis.

26. Mastostethus humero-notatus. (Tab. XXXVI. fig. 12.)

. Flavous, a transverse band on the head, the antenne, the disc of the thorax, the scutellum, tibie, and tarsi,

black ; elytra fulvous, a small spot on the shoulder, and the greater part of the disc, black.

Length 3% lines.

Hab. Panama, Volcan de Chiriqui (Champion).

M. humero-notatus again closely resembles M. panamensis and Wl. imitans, but differs

from both in the small triangular additional humeral spot, as well as in other parti-

culars. The head is fulvous and has a black spot at the extreme base, and a transverse

black band between the eyes, and near the inner margin of the latter are some distinct

punctures. ‘The antenne are black. The thorax agrees in shape and coloration with

that of the two preceding species, and shows no trace of punctures; the middle of the

disc is occupied by a broad black band which extends from the base to the anterior

margin, the sides of this band being nearly straight and without indentation. The

scutellum is black, and smaller than in UM. imitans. The elytra have no postbasal

depression, and are rather more strongly punctured than in the two preceding species ;

the lateral margin is not accompanied by a smooth narrow space as in Vf. imitans; the

shoulder is occupied by a triangular-shaped black spot, and the black portion of the

MASTOSTETHUS.—AGATHOMERUS. 63

disc commences a little below the base and ends at some distance from the apex (if

the black is taken for the ground-colour, the elytra may be described as having a

narrow oblique transverse band at the base and the apex fulvous, with the extreme

lateral margin also of this colour). The underside is flavous, with the exception of a

small black spot on the sides of the thorax, and another on the side-pieces of the meso-

and metasternum. The femora are flavous, the two anterior pairs streaked with black

above; the tibie and tarsi are entirely black. The metasternum, as in the preceding

species, is raised into a conical projection.

Four specimens, all agreeing in the above particulars.

27. Mastostethus octomaculatus. (Tab. XXXVI. fig. 14.)

Testaceous, the base of the head, the basal joints of the antennx, the scutellum, the sides of the breast, and

the tibise, black ; thorax with a black basal band; elytra remotely punctured, black, each with a round

spot at the base, a transverse one at and another below the middle, and a small spot at the sides of the

base, flavous; femora strongly dentate.

Var. Thorax without black band, the two anterior elytral spots confluent, the femora spotted with black.

Length 4—43 lines.

Head rather closely punctured, flavous, the upper portion, labrum, and mandibles black; antennse compara-

tively long, extending beyond the base of the thorax, the four basal joints and the upper surface of the

following three joints black, the rest fulvous ; thorax twice as broad as long, the sides straight, the surface

with some fine punctures, obscure testaceous, the basal margin with a narrow black stripe which does

not extend to the sides; scutellum black; elytra distinctly and rather remotely punctured, each with

three large spots (a round one at the base, a similar but larger spot near the apex, and one of more

transverse shape at the middle), a small spot also being placed on the lateral margin at the sides of the

shoulders, the spots divided from each other by narrow black bands of the ground-colour ; below fulvous,

the middle portion of the anterior femora, the tibiz, and the sides of the breast, black, the posterior

femora also streaked with black above, the latter armed with a strong tooth near the apex in the male,

the tarsi black.

Hab. Panama, Bugaba (Champion).

M. octomaculatus may be known from its allies by the elytra having six (three on

each) large testaceous or flavous spots, and also a small lateral one at the base.

The variety has the two anterior spots on the disc joined into a somewhat pear-

shaped single spot ; in this specimen the posterior femora have their outer half entirely

black, but the narrow black band on the thorax is absent. WU. sexguttatus, Lac., from

Guiana, seems to be a closely allied species; but differs in the absence of the small

shoulder-spot, and in the thorax having a black discoidal band, as well as in other

particulars. A typical example is figured.

AGATHOMERUS (p. 24).

Agathomerus rufus (p. 24).

To the locality Mexico, add :—Ventanas (Yorrer), Puebla, Cuernavaca, Panistlahuaca,

Oaxaca, Tuxtla, Tehuantepec (Sal/é).

There are some specimens contained in the Sallé collection in which the head has a

small black spot on the vertex and the thorax a similar one on the disc; these examples

64 PHYTOPHAGA.—SUPPLEMENT,

thus resemble A. saliei, from which they differ, however, in the elytra being entirely

fulvous and also in the smaller size.

Agathomerus dubiosus (p. 24).

To the locality Mexico, add :—Cuernavaca (Sal/é).

In the typical specimens contained in my collection the scutellum is black; in the

example from Cuernavaca it is fulvous. A. dudiosus differs from A. rufus, to which it

is otherwise closely allied, in the lower surface of the femora and the underside being

black ; but it is possible that these differences may be due to variation.

MEGALOPUS (p. 26).

2. Megalopus violaceo-fasciatus. (Tab. XXXVI. fig. 15.)

Elongate, testaceous, the base of the head and the breast black ; thorax with two transverse grooves, impunc-

tate; elytra very finely and remotely punctured, each with a triangular spot at the base, a transverse one

before the middle, and a large ovate spot near the apex, dark violaceous; legs spotted with black.

Length 43 lines.

Head broad, punctured near the eyes, the upper portion to the antenne black, the lower portion flavous ;

antenn extending to the base of the elytra, pale fulvous, the lower joints entirely, and the following three

or four joints partly, black; thorax about one half broader than long, somewhat convex, the sides slightly

rounded at the middle, the surface with a narrow, transverse anterior, and a similar posterior groove,

impunctate, obscure testaceous ; scutellum partly black and partly testaceous ; elytra narrowed posteriorly,

the base slightly raised, the surface remotely and finely punctured, testaceous, a triangular-shaped basal

spot, a transverse oblique one before the middle, and a large subtriangular spot near the apex of each,

dark violaceous-blue ; below testaceous, a spot near the anterior cox, the breast, the four anterior

femora above, the outer edges of the tibiee, and the tarsi, black.

Hab. Panama, Volcan de Chiriqui (Champion).

A single specimen. The elytra have the shoulders very prominent, their anterior

margin in the shape of an acute oblique ridge; the two anterior spots are placed close

together, but the posterior ones are divided by a larger space; neither of the spots

extend to the lateral margin.

Many specimens, which agree perfectly with Lacordaire’s description. The small

testaceous spot visible in the type near the apex of the elytra in the male is, however,

absent in all the examples before me. All the females have three oblique testaceous

bands on the elytra, as described by Lacordaire; the males possess only a very narrow

single band, placed at the middle, the rest of the surface being black. The posterior

tibie in the male are very strongly curved, in the female much less so. In some

specimens the elytra are entirely black in the male.

TITUBGA. 65

TITUBEA (p. 26).

Titubea mutabilis (p. 27).

To the localities given, add :—Mexico, La Noria in Sinaloa, Ventanas in Durango,

Acapulco, Iguala, Chilpancingo in Guerrero (Hége), San Miguel, Playa Vicente,.

Oaxaca, El Cameron, Cordova, Juquila (Sallé), Atoyac in Vera Cruz, Cuernavaca (Hi. #1.

Smith), Temax in North Yucatan (Gawmer); Guatemaza, Capetillo (Champion).

In some specimens from Mexico the black colour of the elytra predominates to such

an extent as to leave only the shoulders and a small apical spot fulvous; all the

specimens from Yucatan are smaller in size.

Titubea rufifrons (p. 27).

_ To the Mexican locality given, add:—El Cameron (Sallé), Atoyac in Vera Cruz

(1. H. Smith).

As already remarked, 7’. rujifrons and T. mutabilis may be but varieties of the same

species ; even the additional material since received does not enable me to separate

these insects satisfactorily, the different specimens varying considerably in coloration

and also in punctuation. The male of 7. rujifrons differs from that of T. mutabilis, as

a rule, in general colour and in the want of the transverse elytral band; but the

females of both are alike and cannot be separated. I may further add that the

cedeagus of the male in the two insects is similar.

Titubea sphacelata (p. 27).

To the locality Mexico, add :—Cuernavaca (Saldé).

Titubea sanguinipennis (p. 27).

To the localities given, add :—Mexico, Tapachula in Chiapas (Hodge); Guatema.a,

Escuintla, Capetillo, Panzos, Teleman (Champion); Panama, Volcan de Chiriqui

(Champion).

It is quite possible that the specimen figured as the male of this insect (Tab. II.

fig. 16) in reality represents a closely allied but distinct species. Several other males,

as well as a good many females, since received seem at first sight to be totally different

in coloration. to the typical form of 7’. sanguinipennis (Tab. II. fig. 17); and I should

regard these as certainly distinct, if I had not intermediate examples before me which

_it is impossible to refer with certainty to either of the two forms. In nearly all the

specimens from Panzos, the city of Guatemala, and Zapote, and in the one from

Chontales, the upper surface is pale fulvous; the thorax has either a transverse black

basal band or spots; the elytra have one or two basal spots of variable size and a

narrow black band (generally constricted at the suture) below the middle; and the

66 PHYTOPHAGA.—SUPPLEMENT.

underside and legs are usually fulvous, but specimens occur with black underside.

The other or more typical form is well represented in fig. 17, all the specimens

obtained at Tapachula, as well as a single male at Escuintla (which certainly seems to

better represent this sex of 7. sanguinipennis than the figure given of the variety),

being thus coloured; this male has a narrower and entirely black thorax, agreeing in

that respect with the females of 7. sanguinipennis. I have, however, received Guate-

malan specimens from the Museum of Stuttgart which are intermediate between these

two forms, these specimens having the thorax of the paler form and the elytra of the

darker red variety, and the legs either black or fulvous. It seems to me that all these

examples must be referred to one and the same species: they cannot be separated on

such variable characters as the colour and markings of the upper surface and the

sculpture of the thorax.

6. Titubea brevilineata. (Tab. XXXVI. fig. 18.)

Black; the basal joints of the antenne and the labrum fulvous ; thorax fulvous, impunctate; scutellum black ;

elytra finely and semiregularly punctured, the suture, a marginal stripe at the middle, and an abbreviated

stripe on the disc, black.

6. Thorax with two small black spots; legs fulvous, the tarsi black.

Length 3}-4 lines.

3. Head finely rugose between the eyes, the vertex smooth and shining, black, with a small fulvous spot

near each eye; anterior margin of the clypeus deeply concave-emarginate, fulvous, as well as the labrum

and mandibles, the extreme apex of the latter black ; antennz not extending to the base of the thorax,

the fifth and following joints strongly serrate, black, the lower four joints fulvous, the third joint monili-

form and not longer than the second; thorax more than twice as broad as long, the sides strongly

rounded, the posterior margin but slightly produced at the middle, the surface with some very minute

punctures, fulvous, with a small obscure spot on each side; scutellum black, its apex raised, the base

pubescent; elytra finely and closely punctured, testaceous, the sutural margin narrowly black, a narrow

black stripe occupying the lateral margin from before to below the middle, and another narrow, slightly

eurved, black line (parallel to the lateral stripe, and not extending to the base or apex) being placed at

the middle of the disc; legs fulvous, the anterior tibie partly, and the tarsi entirely, black.

Hab. Mexico, Refugio in Durango, Durango city, Jalapa (Hége).

T. brevilineata seems closely allied to T. sphacelata, from which it differs in the

narrow longitudinal discoidal stripe of the elytra, this being constant in the four

specimens before me. In the female insect the legs are sometimes fulvous, sometimes

black ; the thorax is, as usual, less transverse and more shining than in the male.

7. Titubea hogei. (Tab. XXXVI. fig. 16.)

3. Pale fulvous ; elytra opaque, pale testaceous, finely punctured ; anterior legs elongate, the tibie curved ;

sides of the breast darker.

2. Underside black ; elytra more strongly punctured.

Length 3-34 lines. ‘

¢. Head fulvous, the vertex smooth, the lower portion finely strigose, the epistome separated from the face

by a distinct triangular groove; the anterior margin of the clypeus deeply concave-emarginate in the

middle and on each side; the apex of the mandibles black ; antennz black, the lower four joints fulvous,

the third joint moniliform, the fifth and following joints strongly transversely serrate; thorax more than

twice as broad as long, the sides strongly rounded, the surface with a few minute punctures and some

TITUBGA. 67

irregular depressions, of which a more strongly marked one is placed near the anterior angles; scutellum

fulvous; elytra narrower than the thorax, very pale testaceous, opaque, with indistinct rows of fine

punctures, the interstices sparingly clothed with short fulvous hairs; below and the legs fulvous, the

breast black; anterior legs much longer than the others, their tibie strongly curved at the apex, their

tarsi piceous and with the first joint as long as the two following ones together.

Hab. Mexico, Iguala in Guerrero (Hége).

This species, of which only one male and three females were obtained, may be at

once known from its allies by the absence of any dark markings above, the whole

upper surface being pale fulvous. The females (in which, as usual, the thorax is less

transversely-shaped) have the entire underside black and clothed with yellowish

pubescence; and the elytra much more strongly punctured and the punctuation

arranged near the suture in double rows.

8. Titubea guatemalensis.

Fulvous, the terminal joints of the antenne, the anterior tibie and tarsi, and the breast, black; elytra testa~

ceous, almost imperceptibly punctured, the interstices sparingly clothed with short black erect hairs.

Length 33 lines.

Hab. Guatemata, San Gerénimo (Champion).

Only a single male specimen of this species, which I must separate from the pre-

ceding, is before me. Like 7. hégei, the colour of the upper surface is pale fulvous,

but the elytra are almost impunctate and their pubescence is black and only visible in

certain lights; two very small obscure spots (which may be the remnants of a band)

are visible below the middle of the latter; the anterior tibize are entirely black, and

not so strongly curved as in the male of 7. hégei; and the general shape of the body

is much broader and more robust. T. guatemalensis may, however, be only a local

form of 7. héget.

9. Titubeea villosa. (Tab. XXXVI. fig. 17.)

Black, pubescent; the labrum fulvous, spotted with black; elytra fulvous, clothed with short, pubescence, a

broad transverse band below the middle, extending upwards along the suture, black.

Length 3-33 lines.

Hab. Mexico, San Miguel, Etla (Sal/é).

This species exactly resembles in colour 7’. mutabilis, and can only be separated from

it by the short greyish pubescence which covers the entire upper surface. The head

is either entirely black or has two fulvous spots at the sides; the three basal joints of

the antenne are generally fulvous, but sometimes the first joint is black; the thorax is

- entirely black in some specimens, or margined with flavous in others; and the broad

elytral band varies as much in width and length as it does in 7. mutabilis. The single

male specimen before me is larger and has, as usual, a more transversely-shaped thorax,

and the four anterior femora fulvous below. In all examples the elytra are finely

margined with black at the apex and at the posterior portion of the suture.

GYNANDROPHTHALMA (p. 28).

Gynandrophthalma agilis (p. 28).

To the locality Mexico, add :—Tuxtla, Cordova, Teapa (Sal/é), Acapulco in Guerrero

This species varies much in regard to the amount of the fulvous colour of the

thorax ; the size is equally variable.

Gynandrophthalma aviculus (p. 29).

To the locality given, add :—Mexico, Peras (Sal/é).

4 (a). Gynandrophthalma ruatanensis.

Fulvous, pubescent below, the terminal joints of the antenna, the tarsi, and breast, black; thorax and elytra

shining, fulvous, the latter strongly and semirugose-punctate.

Length 27 lines.

Head rather flattened, impunctate, shining; the terminal joints of the palpi black; antenne extending to the

base of the thorax, the four or five lower joints fulvous, the rest black, strongly flattened, the second and

third joints very small; thorax three times broader than long, the sides rather deflexed, widened towards

the base, the surface impunctate, the posterior margin only with some punctures; scutellum broadly

triangular, strongly pointed at the apex, impunctate; elytra convex, subcylindrical, strongly and rather

closely punctured, the punctures near the suture arranged in somewhat regular rows; underside clothed

with fulvous pubescence, the breast black; the tibia sometimes fuscous, but generally fulvous, the tarsi

black.

Hab. Honpuras, Ruatan Island (Gawmer).

The entirely fulvous and shining upper surface, the absence of any markings, and

the strongly punctured elytra distinguish G. ruatanensis. from any of its congeners

inhabiting our region.

4 (s). Gynandrophthalma panamensis.

Obscure fulvous or fuscous, densely covered with silvery pubescence below; head black ; thorax fulvous,

impunctate ; elytra finely punctured, fulvous, a triangular spot at the shoulder (prolonged inwards), a

transverse band below the middle, and the apex, black.

Length 2-23 lines.

Head black, impunctate, with a triangular groove between the eyes; the anterior margin of the clypeus

deeply concave at the middle; labrum obscure fulvous ; antenne black, the four basal joints fulvous, the

terminal joints strongly flattened ; thorax nearly three times broader than long, fulvous, the anterior

margin narrowly black at the middle, the surface impunctate; scutellum black at the base, its apex

fulvous and acute; elytra rather remotely and finely punctured, fulvous, with a short subtriangular or

subquadrate band at the shoulder (which extends inwards towards the suture but does not touch it), a

transverse band of variable width below the middle (extending to the sutural but not to the lateral

margin), and the apex and part of the apical margin, black; underside and the legs black, the base of

the femora more or less fulvous; abdomen obscure fulvous, like the breast densely covered with silvery

pubescence.

- GYNANDROPHTHALMA.—MEGALOSTOMIS. 69

Two specimens, one of which is nearly double the size of the other, were obtained

by Mr. Champion. This species differs from all others described in this work in the

pattern of the elytra. |

Gynandrophthalma leucognatha (p. 29).

To the locality Mexico, add:—Pachuca in Hidalgo, Juquila (Hége), Guanajuato, La

Parada, Oaxaca (Sallé).

Although none of the specimens received from the above localities quite agree with

Lacordaire’s description of G. leucognatha, I do not think it advisable to describe them

as new, taking into consideration the great variability of the species of the present

family ; and I am not even sure whether these Mexican specimens may not equally

well be varieties of G. quadripartita, this latter species having been described by

Lacordaire from one female specimen only. In the examples from the above-mentioned

localities, the head and thorax agree with Lacordaire’s description of G. leucognatha,

but the elytra differ in having black (instead of bluish) markings; the sutural band is

very narrow and of equal width (not wider anteriorly); there is only a small spot

(instead of a large triangular one) at the middle of each elytron, this spot not being

connected with the black lateral margin; the basal margin and a spot on each shoulder

are black ; and the punctuation is very strong and continued to the apex. The colour of

the legs agrees with the description of that author. In one specimen the posterior spot

of the elytra is subquadrate and in the shape of a transverse band, and the sutural band

is widened posteriorly ; another has the entire posterior half of the elytra black.

It will be seen, therefore, that in a species so variable no reliance can be placed on

colour or pattern, and that differences in this respect cannot be considered specific.

MEGALOSTOMIS (p. 29).

Megalostomis pyropyga (p. 30).

To the localities given, add :—Muexico, Ventanas (Forrer), Oaxaca, Capulalpam, Vera

Cruz, Etla, Cuernavaca, Puebla, Tehuantepec (Sallé), Matamoros Izucar, Huetamo in

Michoacan, Guadalajara in Jalisco, Chilpancingo in Guerrero, Acapulco (Hége) ;

SatvaDor (Sallé) ; Nicaracua, Chontales (Belt).

Many specimens obtained by Herr Hége. This species is distinguished by the

metallic cupreous anterior margin of the thorax, as well as by the similarly-coloured

apical spot of the elytra, although this latter is sometimes very obscure and even

absent.

(a). Megalostomis metallica. (Tab. XXXVI. fig. 19.)

Black, densely pubescent below ; above metallic purplish or greenish ; thorax sparingly and finely punctured

elytra more closely and distinctly punctate, the basal and sutural margins metallic green.

Length 3 lines.

70 PHYTOPHAGA.—SUPPLEMENT.

Of rather depressed, posteriorly narrowed shape; the head impunctate, with the exception of a row of deep

punctures near the inner margin of the eyes, the latter distinctly notched, the surface obscure greenish,

variegated with purplish ; the anterior margin of the clypeus deeply concave-emarginate ; labrum fulvous ;

antenne bluish-black, the lower three joints fulvous, the first stained with metallic green above; thorax

twice as broad as long, the sides strongly deflexed anteriorly, narrowed in front, the posterior margin

broadly rounded and produced at the middle, the surface with some very fine and distantly placed punc-

tures and an oblique transverse depression on each side, where the punctures are much deeper than on

the disc, the latter obscure greenish-seneous or purplish; scutellum very broad, subpentagonal, purplish

or greenish, impunctate; elytra rather flattened, gradually narrowed behind, with a short depression

below the shoulder, dark purplish, finely and rather closely punctured, the punctures arranged near the

suture in irregular rows; underside covered with dense greyish pubescence ; legs obscure fulvous, with a

slight metallic gloss.

Hab. Panama, Volcan de Chiriqui (Champion).

This species is not difficult to distinguish, on account of its metallic colour, which

changes from purple to greenish according to the way the specimens are viewed.

2 (8). Megalostomis affinis.

Subdepressed, narrowed behind, below black and densely pubescent, above dark greenish-wneous ; thorax finely

and sparingly, the elytra more closely, distinctly, and semiregularly, punctured.

Length 4 lines.

Hab. Guatemata, Panima in Vera Paz 1500 feet (Champion).

M. affinis, of which only a single specimen was obtained, is no doubt closely allied to

M. metallica, but differs sufficiently from that species, as well as from WU. splendida, to

be regarded as specifically distinct. In general shape MW. affinis agrees with the pre-

ceding species ; but it is rather larger, the head is more strongly and closely punctured

(especially near the eyes), the clypeus is bright metallic green, bordered with cupreous

above, and the antenne do not extend further than the middle of the thorax and are

black with the exception of the first three joints, these being eneous; the thorax is

similar in shape to that of I. metallica, and has a narrow green and cupreous basal

margin ; the scutellum is metallic green, its base cupreous; the elytra are of the same

obscure dark greenish colour as the thorax, and have a very narrow bright metallic

green sutural border, their punctuation being more strongly impressed than is the case

in M. metallica, and the punctures are placed rather regularly in lines; and the legs

are nearly black. M. affinis may principally be distinguished from WM. metallica by its

larger and more robust shape, the dark green (not purplish) colour, and the more

strongly punctured elytra. |

Megalostomis notabilis (p. 30).

To the locality Mexico, add :—Acapulco, Iguala in Guerrero (Hoge).

M. notabilis is of more cylindrical and posteriorly less narrowed shape than MW. dimi-

diata, which it otherwise much resembles. The fulvous portion of the elytra extends

to about one third their length; and the pygidium is furnished with a distinct conical

tubercle near the apex, this being absent in WM. dimidiata.

MEGALOSTOMIS. | 71

Megalostomis dimidiata (p. 30).

To the localities given, add :—Mextco, Monclova in Coahuila (Dr. Palmer), Ciudad

in Durango 8100 feet (Forrer), Durango city, Zapotlan, Colima city, Guadalajara in

Jalisco, Chilpancingo in Guerrero, Irapuato, Matamoros Izucar in Puebla, Tacambaro

in Michoacan (Hége), Oaxaca, Capulalpam, Cuernavaca, Guanajuato, Vera Cruz (Sailé).

Numerous additional specimens have been received from Mexico; these vary in the

pattern of the elytra, that is in regard to the amount of fulvous and black. In the

variety figured (Tab. II. fig. 14) the black colour is absent; in the normal form the

anterior half of the elytra is fulvous. The more conical, posteriorly narrowed, shape

and the absence of the conical tubercle on the pygidium (instead of which a narrow

denuded space with a raised central ridge is visible) principally distinguish IM. dimidiata

from M. notabilis.

Megalostomis tomentosa (p. 30).

To the localities given, add:—MeExico, Oaxaca, Cuernavaca (Sallé), Colima city,

Acapulco, Iguala in Guerrero, Matamoros Izucar, Tehuantepec (foge); GUATEMALA,

Las Mercedes (mus. Stuttgart); Panama, Bugaba (Champion).

The additional material, since received, enables me to add some more particulars in

regard to this species :—The antenne vary in length according to the sexes, and extend

in some specimens quite to the middle of the thorax ; the black posterior portion of the

elytra often varies considerably in extent, and assumes in some examples the shape of a

narrow transverse band, leaving the apex fulvous. I. tomentosa is not more than half

the size of WV. dimidiata, and the elytra are always very finely rugose and transversely

wrinkled. In the original description I have omitted to state that the tibie are more

or less fulvous and densely pubescent and the tarsi black. The individuals obtained

in the State of Panama are all of small size (3 lines), and some are so densely clothed

with white pubescence as to nearly obscure the colour of the upper parts; but I am

unable to detect any other difference between these specimens and those from Mexico.

5 (4). Megalostomis femorata. (Tab. XXXVI. fig. 20.)

Subcylindrical, parallel, black, pubescent; thorax twice broader than long, finely punctured and pubescent ;

elytra finely rugose-punctate and pubescent, fulvous, the posterior portion of the disc and the suture black ;

posterior femora dentate.

Length 3 lines.

Hab. Mexico, Ventanas in Durango (Hége).

The single male specimen obtained by Herr Hoge during his second expedition

differs so much from the corresponding sex of the preceding species in the shape of its

thorax and in the tooth near the apex of the posterior femora that I must separate it,

although the general system of coloration is exactly similar. The thorax in JZ. femorata

is much less transverse than is the case in I. tomentosa, and its lateral margin (instead

72 PHYTOPHAGA.—SUPPLEMENT.

of being rounded at the middle) is rounded anteriorly and distinctly narrowed or con-

stricted at the base; the median lobe of the posterior margin is not rounded, but

straight; and the pubescence on the disc is very long. The elytra scarcely vary in

punctuation from those of M. tomentosa, and the black portion does not extend to the

lateral nor to the apical margin. The legs are obscure fulvous; the posterior femora

are dilated into a distinct tooth near the apex; and the tarsi (as well as the antennz)

are black.

Megalostomis flavipennis (p. 31).

To the locality given, add:—Panama (Boucard), Bugaba, Volcan de Chiriqui

(Champion).

In some of the Panama specimens the tibie and tarsi are flavous; in all, the elytra

(instead of being flavous as in the type) are fulvous, and in one specimen there is a

small black spot placed on the shoulders.

7. Megalostomis punctatissima. (Tab. XXXVI. fig. 22.)

Subcylindrical, convex, black, finely pubescent ; thorax extremely finely and closely punctured; elytra very

closely but distinctly punctured, finely pubescent, fulvous, a spot on the shoulders, and the posterior two-

thirds, bluish-black.

Length 4 lines.

Hab. Guaremata, San Gerdénimo (Champion).

This species, of which we have received but a single specimen, at first sight might

easily be mistaken for M. dimidiata, as the coloration is exactly similar; the differences

are, however, as follows :—The thorax in UW. punctatissima is distinctly more narrowed

in front and less transverse, and its punctuation (instead of being distinct as in M/. dimi-

diata) is extremely close and fine, so as to be scarcely visible, and the colour is not

black but bluish ; the elytra also have their dark portion with a distinct bluish gloss,

and the punctuation is like that of the thorax and finer than in the allied species, and

the fulvous colour of the anterior third is narrowed at the suture, the black portion

extending upwards nearly to the scutellum; the head is punctured like the thorax ;

and the antenne are black, with the third joint only fulvous.

8. Megalostomis fulvipes. (Tab. XXXVI. fig. 21.)

Subcylindrical, black, pubescent, the sides of the thorax and the legs fulvous; elytra rather strongly and

closely punctured, a large subtriangular band at the shoulder, and a spot at the apex, fulvous.

Length 3 lines.

Head very finely and closely punctured, finely pubescent; the anterior margin of the clypeus semicircular;

labrum black; eyes notched; antennz fuscous, the basal joint black, the following two joints fulvous

thorax subcylindrical, extremely closely and finely punctured and pubescent, the sides slightly narrowed

towards the base, fulvous, the rest of the surface black; elytra subcylindrical, strongly punctured and

legs fulvous, pubescent, the tarsi black.

Hab. Satvapor (Sallé).

A single specimen, differing entirely from all its allies in the system of coloration,

especially in the broad fulvous sides of the thorax and in the similarly-coloured legs.

The Panama specimens and those from Venezuela contained in my collection agree

so well with Lacordaire’s description that I must refer them to this species. The male

is furnished with very robust and long mandibles, the right and larger one of which

is strongly bidentate. A male specimen from Taboga Island is figured.

Hab. Panama, Bugaba (Champion).—Amazons }.

Two specimens, agreeing in every respect with the type in my collection.

In a collection of Coleoptera just received from Guatemala there is an interesting

new species of Megalostomis :—

11. Megalostomis viridifasciata.

Dark cupreous, the base of the head and the posterior margin of the prothorax metallic green ; elytra closely

and rather strongly semipunctate-striate, the suture and a short transverse band at the middle metallic

green.

Length 3-4 lines.

Head irregularly punctured near the eyes, dark cupreous, the base and the anterior margin of the epistome

metallic green ; antenne as long as the thorax, black, the basal joints cupreous ; thorax strongly narrowed

in front, the sides straight, the base sinuate on either side of the median lobe, the surface finely and very

remotely punctured on the disc, much more strongly and subrugosely so at the sides, the latter with a

more or less distinct transverse depression towards the base; scutellum metallic green, its base cupreous ;

elytra rather strongly depressed below the shoulders, the latter very prominent, the surface strongly and

closely (but not very regularly) punctate-striate, the suture very narrowly (more broadly so just before

the apex) metallic green, the disc of each elytron with a short and narrow metallic green transverse band

at the middle; underside and legs cupreous, closely covered with whitish pubescence.

Hab. Guatemata, Coban in Vera Paz (Conradt).

M. viridifasciata agrees almost entirely with J. splendida in its system of coloration,

but in its shape, size, and sculpturing it approaches MZ. metallica. In the last-named

species the thorax is, however, less straight at the sides and subangulate near the

base; the elytra are more finely and much less regularly punctured and devoid of

the green metallic band ; and the legs are fulvous.

Five specimens, captured in April 1888.

To the locality Mexico, add :—Presidio (Forrer), El Camaron (Saldé), Cordova, Zapotlan

The Mexican specimens before me agree entirely with those from North America

contained in my collection. The thorax in this species is longer than in C. cribrata,

and has a smooth narrow central line; the elytra are almost regularly punctate-striate* ;

and the general size of the insect is much larger than that of C. cribrata.

4, Coscinoptera purpurea. (Tab. XXXVI. fig. 25.)

Obscure purplish, densely pubescent below, more finely pubescent above; antenne and legs fulvous; thorax

twice as broad as long, finely punctured as well as the elytra.

Length 13-23 lines.

Hab. Panama (Boucard), Bugaba, David, Tolé (Champion).

C. purpurea seems to differ from the preceding and other species of the genus by the

upper surface being dark purplish in colour and clothed with very fine whitish pubes-

* In Crotch’s description the elytra are stated to be ‘ subseriate, impunctate,” instead of “ subseriate-

punctate.” |

COSCINOPTERA.—EURYSCOPA. 75

cence. The antenne have the basal joint blackish, the others fulvous, the second and

third joints being very small. The labrum is generally fulvous. The thorax. is at least

twice as broad as long (which separates C. purpurea from C. desmiphora, Lac., in which

the thorax is stated to be nearly as long as broad); its punctuation is very close and

fine, while that of the elytra, although as fine, is more rugose in appearance. The

specimens before me, however, vary in the intensity of the punctuation and also in size ;

but, judging from examples collected together in the same localities, I believe them to

represent one and the same species.

5. Coscinoptera quadrillum ?

Coscinoptera quadrillum, Lac. Monogr. in Mém. Soc. Liége, v. p. 514°.

Hab. Mexico (Sallé).—Braziu 1.

A single specimen contained in the Sallé collection agrees very nearly with the

description of C. guadrillum, a species said to come from Brazil. Most of the species

of this and the following genus are, however, so closely allied that they can hardly be

identified for certain without comparison with the type. In the Mexican example

before me the thorax is obscure eneous, very finely and closely punctured and pubes-

cent, and about twice as broad as long; the elytra are black, scarcely more strongly

punctured than the thorax, and have a subquadrate red humeral patch (extending

inwards to the middle of the base and downwards to a fourth of the elytral length, and

reaching to the lateral margin); and the antenne, femora, and tibia are fulvous, and

the tarsi black.

EURYSCOPA (p. 31).

Euryscopa pilatei (p. 32).

Lacordaire compares this species with #. pulchella, and says that it resembles it

entirely in form; he, however, describes the thorax of KE. pulchella as “scarcely one

fourth broader than long,” while in Z. pilatei (and in most other species of Huryscopa)

the thorax is at least twice as broad as long. It is therefore difficult to account for

Lacordaire’s statement in his otherwise excellent descriptions; and it is not likely that

he referred to another species, as all the other particulars agree entirely with Z. pilatet,

of which correctly-named specimens are also contained in the collection of M. Sallé

and that of Mr. Baly.

Euryscopa scapularis (p. 32).

To the locality Mexico, add:—Cuernavaca, La Parada, Guanajuato, Izucar (Sal/é),

Iguala in Guerrero, Irapuato, Colima city, Huetamo (Hoge), Temax in North Yucatan

(Gaumer) ; GuateMaLa, San Geronimo (Champion), Llano grande (mus. Stuttgart).

E. scapularis differs principally from H. pilatet in its black and longer thorax. It

76 _ PHYTOPHAGA.—SUPPLEMENT.

varies considerably in size; and the scutellum is clothed with white hairs (not smooth

as in J. pilatei). Lacordaire describes the second to the fifth joints of the antenne

as fulvous; in all the specimens I have examined the second and third joints only are

of that colour. :

5. Huryscopa nigritarsis. (Tab. XXXVII. fig. 1.)

Broadly subcylindrical, black; legs fulvous, the tarsi black; thorax sparingly punctured on the disc ; elytra

distinctly punctured anteriorly, very finely so below the middle, the anterior third and a round spot near

the apex fulvous.

Length 23 lines.

Hab, Panama, Bugaba (Champion).

E. nigritarsis, of which a single female specimen only is before me, seems closely

allied to F. carnifer and LF. specularis, Lac., without agreeing sufficiently to identify it

with either of these species. The thorax in the Panama insect is at least twice as

broad as long, finely and closely punctured and pubescent at the sides, nearly smooth

and impunctate at the middle of the disc. The scutellum is much broader than long,

and closely punctured. The elytra, which are scarcely, if at all, narrowed posteriorly,

are distinctly, but not very strongly, punctured anteriorly and very finely so from the

middle downwards; the basal third is occupied by a perfectly regular fulvous band of

even width, which extends to the lateral and sutural margins and includes the humeral

callus; and there is an oval spot close to the apex of each.

E. nigritarsis differs, therefore, from 2. carnifex by the broad thorax and the black

tarsi; and from F. specularis by the smaller eyes, the differently punctured red thorax,

and the fulvous band of the elytra occupying the entire base. ‘The antenne are short,

and their second and third joints are fulvous; the prosternum is rather broad and of

even width.

6. Kuryscopa mexicana. (Tab. XXXVII. fig. 2.)

Broadly ovate, subcylindrical, black ; head and thorax finely pubescent and closely punctured ; elytra deeply

punctate-striate, with a broad transverse fulvous band at the base, the band not quite extending to the

suture nor to the humeral callus.

Length 4 lines.

Head longer than broad, much flattened between the eyes, finely punctured and closely pubescent, the disc

piceous ; labrum fulvous; antenne not quite extending to the base of the thorax, black, the third joint

fulvous ; thorax slightly broader than long, the sides strongly narrowed anteriorly and very much deflexed,

the median lobe perfectly straight, the surface very closely and rather finely punctured, clothed at the sides

with long whitish pubescence, the disc very sparsely covered ; scutellum pubescent and punctured ; elytra

broad at the base, gradually and slightly narrowed posteriorly, the punctuation very deep anteriorly and

fine towards the apex, the fulvous basal band occupying rather more than the anterior third and not quite

extending to either the basal or sutural margins, the humeral callus remaining of the black ground-colour

and in the shape of a small spot; underside and legs thickly pubescent, black, the tibis obscure fulvous,

the last abdominal segment with a deep fovea.

Hab. Muxico, Cuernavaca (Sallé).

Many specimens were obtained by Mr. Champion of this apparently not uncommon

and handsome species. Examples occur in which the posterior band of the elytra

occupies the entire apical portion. Lacordaire, in his excellent description, does

not mention that the apical margin of the elytra as well as the suture is narrowly

black.

8. Euryscopa fulvilabris.

Subcylindrical, black; labrum fulvous ; thorax with a longitudinal central ridge, pubescent; elytra strongly

punctate-striate, each with a subquadrate red humeral spot enclosing the callus.

Length 2 lines.

Hab. Mexico, Ventanas in Durango (Hége).

Closely allied to #. scapularis, Lac., but at once separated by the bright fulvous

labrum, the longer antennz (which extend to the base of the thorax), and the distinctly

raised longitudinal line in the centre of the thorax. The scutellum is pubescent, as in

£. scapularis; but the red humeral spot is quite different in shape, it being nearly

square (instead of elongate) and surrounding the callus (this part is always black in

E. scapularis, and its inner margin is oblique at the base).

A single specimen.

9. Kuryscopa villosa. (Tab. XX XVII. fig. 3.)

Subcylindrical, black, pubescent ; labrum, the basal joints of the antenne, and the tibiz fulvous ; elytra each

with an oblique red spot, finely pubescent, semiregularly and extremely closely punctured, the interstices

irregularly rugose.

Length 3 lines.

Head very finely punctured and closely pubescent; labrum fulvous; antenne dentate within from the third

joint, the second, third, and fourth joints fulvous, the rest black, pubescent ; thorax about twice as broad

as long, closely and finely punctured, clothed with rather short white pubescence, the middle of the disc

with a distinct smooth longitudinal line, the median lobe slightly widened and scarcely produced ; scu-

tellum with a few punctures and hairs; elytra cylindrical, crowded with larger and smaller punctures,

which are irregularly arranged in lines, the interstices sparingly pubescent and slightly convex, the red

spot commencing below the humeral callus, gradually narrowing behind, and obliquely extending nearly

to the suture; tibize fulvous, the femora and tarsi black, pubescent like the underside.

Hab. Mexico, Chilpancingo and Acapulco in Guerrero (Hége).

78 PHYTOPHAGA.—SUPPLEMENT.

The close and irregular punctuation of the elytra and their fine pubescence at once

separate this species from its allies.

10. Euryscopa semistriata. (Tab. XXXVII. fig. 4.)

Subcylindrical, black, finely pubescent; elytra closely and rather irregularly punctured, with longitudinal

rows of larger punctures, finely pubescent, a subquadrate spot at the shoulders reddish-fulvous.

Length 24 lines.

Hab. Muxico, Durango city (Hége).

Like Z, villosa, the present species (of which only a single example was obtained)

has the elytra finely pubescent and the punctures closely and rather irregularly placed ;

the punctuation is, however, finer than in Z. villosa, and interrupted by more regular

rows of closely placed deeper punctures; the red shoulder-spot is very small, almost

quadrate, and occupies the humeral callus. In all these details #. semistriata differs

from Z. villosa. The size is also smaller ; the antenne do not extend to the base of

the thorax, and have, as usual, the second and third joints fulvous; the thorax is twice

as broad as long, finely punctured, and clothed with long white pubescence; and the

legs are entirely black. The punctuation of 2. semistriata does not seem to me to be

irregular enough to place the species in Coscinoptera.

11. Euryscopa longicollis. (Tab. XX XVII. fig. 5.)

Narrowly elongate, black ; head, thorax, scutellum, and underside densely pubescent; elytra each with a small

red humeral spot, closely and strongly punctate-striate, the interstices longitudinally costate.

Length 22 lines.

Head elongate, closely and finely punctured, and clothed with long white pubescence; eyes moderately large ;

the labrum and mandibles black; antenn# extending only to the middle of the thorax, black, the

second and third joints fulvous; thorax elongate, about one half broader than long, subcylindrical, the

sides strongly deflexed, the surface very closely and rather finely punctured, clothed (like the head)

with long white pubescence ; scutellum pubescent; elytra narrowed posteriorly, with closely-arranged

rows of transversely-shaped punctures, the interstices narrowly but distinctly costate (especially near

the apex), the shoulder with a small subquadrate red spot; femora black, the apex of the tibie obscure

fulvous.

Hab, Mexico, Northern Sonora (Morrison).

This species and /. parvula were both labelled #. lecontet by Morrison, although

certainly quite distinct from each other as well as from Z. lecontei ; Crotch, in his short

description of the latter, says that the thorax is coarsely punctured. In #. longicollis

the thorax is decidedly elongate; the interstices of the elytra are costate, and the punc-

tures transverse ; and the red shoulder-spot only extends to the third stria, and leaves the

callus black: these characters, together with the narrowly elongate and comparatively

large size, will assist in the recognition of the species.

Only a single specimen was sent.

EURYSCOPA. 79

12. Kuryscopa fulvipes.

Black ; head and thorax closely pubescent, finely punctured ; elytra each with a large oblique red humeral

spot surrounding the callus, deeply punctate-striate, the interstices convex ; legs fulvous.

Length 2-24 lines.

Hab. Mexico, Presidio (Forrer), Sayula in Jalisco (Hége).

The thorax is twice as broad as long, very finely punctured, and rather more sparingly

pubescent than in /. longicollis. The elytra are impressed with very closely placed

deep round punctures, and have slightly convex interstices; the humeral spot extends

obliquely downwards nearly to the middle, and to the third row of punctures from the

suture—this spot (unlike the corresponding one in #. longicollis) occupies the humeral

callus as well as the lateral lobe. ‘The legs and the second and third joints of the

antenne are entirely fulvous.

The female is much larger than the male, In the four specimens received the

humeral spot is similarly shaped, and the legs are fulvous in colour.

13. Kuryscopa regularis. (Tab XXXVII. fig 6.)

Robust, subcylindrical, parallel, black, the second and third joints of the antenne and the tibic fulvous; thorax

finely punctured and pubescent, the sides obscure reddish; elytra very closely punctate-striate, each with

a narrow transverse red band below the shoulder.

Length 2 lines.

Head finely rugose at the vertex, pubescent; labrum black; antenne extending nearly to the base of the

thorax; the latter twice as broad as long, very closely punctured, the sides finely pubescent, of an obscure

reddish-fulvous colour, and obsoletely depressed, the disc with a narrow obscure smooth central line;

scutellum broad, glabrous; elytra nearly parallel, the basal margin distinctly raised near the scutellum,

the punctures deep and slightly transverse in shape, more finely impressed posteriorly, each elytron with a

narrow transversely-shaped red band, the band extending as far as the third stria from the suture, but not

reaching the humeral callus.

Hab. GuatEMALA, near the city 5000 feet (Champion).

The single, apparently female, specimen before me differs sufficiently from any of its

allies to justify its being treated as distinct; the thorax is extremely closely punctured,

especially at the sides, where the punctures are partly confluent and the ground-colour

obscure reddish; the elytral band commences in front of the humeral callus, and

after extending downwards to about a third of the length of the elytra, turns nearly at

a right angle inwards towards the suture, and the posterior margin of the band is

nearly straight, the anterior one slightly curved. The shape of the elytral band, the

punctuation of the thorax and its colour, and the rather long antenne will help to

distinguish /. regularis.

13. Kuryscopa parvula. (Tab. XX XVII. fig. 7.)

Narrowly elongate, black ; head and thorax densely pubescent, finely and closely punctured; elytra strongly

punctate-striate anteriorly, finely so posteriorly, the shoulder with a red subquadrate spot.

Length 1} line.

80 PHYTOPHAGA.—SUPPLEMENT.

Hab. Mexico, Northern Sonora (Morrison).

This isa very small species which I cannot identify with any Huryscopa yet described,

although it may be identical with one or the other of the North-American forms

described by Crotch. The labrum is black; the antenne are black, but with the second

and third joints obscure fulvous. The thorax is much longer than in Z. pilatei (being

about one half broader than long), finely and rather closely punctured, and clothed

(like the head) with long white pubescence. The scutellum is glabrous, and impressed

with a few punctures. The elytra are rather strongly narrowed posteriorly ; the punc-

tuation is strong anteriorly, but much finer towards the apex, and the punctures are not

very closely placed ; the red shoulder-spot is of an elongate-subquadrate shape, extend-

ing inwards to the middle and downwards to less than a third of the elytral length,

the humeral callus itself remaining of the black ground-colour. The legs are entirely

black. Crotch’s description of #. lecontei is too short and superficial to distinguish that

species from the many closely allied and similarly-coloured forms; the author describes

the thorax as “ coarsely punctured” (so that #. leconte: cannot be identical with £.

parvula), but he does not even mention the colour of the elytra.

14. Kuryscopa [

Black ; labrum fulvous; head and thorax pubescent; elytra regularly punctate-striate, glabrous, a quadrate

spot at the shoulder fulvous.

Length 2 lines.

Hab. Mexico, Hacienda de Bleados in San Luis Potosi (Dr. Palmer).

The single example obtained seems closely allied to #. fulvilabris, but differs from it

in some minor details: the thorax is more finely punctured, and (instead of having a

central raised line) has a broader smooth longitudinal space down the middle; the

scutellum is pubescent (as in #. fulvilabris); the elytra are rather more finely punc-

tured, and the fulvous humeral spot (although not larger and similarly occupying the

callus) is almost quadrate in shape, its inner edge being straight and not oblique. In

the absence of further material I have, at present, only pointed out the differences

between this insect and F. fulvilabris.

PROCTOPHANA (p. 32).

Proctophana basalis (p. 32).

To the localities given, add :—-MExico, Atoyac in Vera Cruz (H. H. Smith); Guate-

MALA, San Gerénimo (Champion); Panama, Bugaba, Volcan de Chiriqui, David

(Champion).

These localities extend considerably the geographical distribution of this species.

PROCTOPHANA —BABIA. 81

2. Proctophana fulvicollis. (Tab. XXXVII. fig. 8.)

Broadly subquadrate, purplish-black ; thorax fulvous, pubescent at the sides ; elytra punctate-striate, a large

transverse band at the base, and an elongate spot at the apex, fulvous.

Length 23 lines.

2. Head dark purplish, the vertex swollen, impunctate, the lower portion closely and strongly punctured near

the eyes, the latter slightly notched ; antenne not quite extending to the base of the thorax, black, the

second and third joints obscure fulvous, the latter smaller than the preceding joint, the others strongly

transversely serrate ; thorax more than twice as broad as long at the base, the sides perfectly straight

though rapidly converging, the disc fulvous, the anterior and posterior margins black, the surface strongly

but irregularly punctured, obsoletely depressed at the sides, the latter pubescent, the posterior margin

strongly oblique at the sides, its median lobe straight at the middle; scutellum black, triangular, impunc-

tate ; elytra broad, not very evenly, but rather strongly, punctate-striate (each elytron with ten rows of

punctures), the interstices slightly transversely wrinkled (when viewed in a certain way), the fulvous

portion surrounded by the black margins and interrupted at the middle by a broad mesially widened dark

purplish band; femora fulvous at the base, the tibie more or less fulvous, closely pubescent ; last abdo-

minal segment with a deep fovea.

Hab. Panama, Volcan de Chiriqui (Champion).

A single female specimen. LP. fulvicollis forms the third known species of the genus

Proctophana ; it has the humeral callus very prominent and the elytral lobe strongly

developed : this latter is closely and irregularly punctured.

DACHRYS (p. 33).

Dachrys bipartita (p. 33).

To the locality given, add:—Panama, Bugaba, Volcan de Chiriqui (Champion).

The Panama examples do not seem to differ from the typical form from Nicaragua

except in size, our specimens varying from one to two linesin length. JD. bipartita

seems to be closely allied to D. pusilla, Lac., but differs from it in the anterior fulvous

portion of the elytra being quadrate in shape and not prolonged suturally.

BABIA (p. 33).

Babia pudica (p. 33).

According to Lacordaire’s description the red basal spot of the elytra commences

below the shoulders; I have seen no species of Babia from Central America thus

coloured.

Babia magnicollis (p. 34).

Though the two specimens before me from Juquila do not quite agree with Lacor-

daire’s description, I must refer them to B. magnicollis, the thorax being comparatively

long (in one specimen, however, it is decidedly broader than long, in the other nearly

as long as broad, the latter agreeing with the description). In these examples the

head is extremely finely granulate; the thorax (which, according to Lacordaire,

shows no trace of punctuation even under the strongest lens) is extremely minutely

BIOL. CENTR.-AMER., Coleopt., Vol. VI. Pt. 1, Suppl., February 1889. m

‘

82 PHYTOPHAGA.—SUPPLEMENT.

punctured, when seen under a high magnifying-power ; and the elytra have the inter-

spaces between the two or three inner strize closely and finely punctured (of which

Lacordaire says nothing). In other details our insect agrees with Lacordaire’s descrip-

tion; the long thorax is, however, the characteristic peculiarity of 2B. magnicollis.

Babia stabilis (p. 34).

To the locality Mexico, add:—Iguala and Acapulco in Guerrero, Cuernavaca in

Morelos, Huetamo in Michoacan (Hoge).

Specimens lately received from Herr Hége agree well with the description of this

species. These have the antenne dentate from the fifth joint; the thorax almost

impunctate (under a very strong lens minute punctures are visible) ; and the elytra

finely and closely punctate-striate, their interstices being also minutely punctured.

These characters and the shape of the red spots of the elytra, as well as the small size

of the insect, agree with the author’s description.

Babia pulla (p. 34). |

To the locality Mexico, add :—Northern Sonora (JJorrison).

‘The Sonoran specimens agree so well with Lacordaire’s description of B. pulla that

I refer them to that species. Crotch (Proc. Ac. Phil. 1873, p. 27) treats the latter as a

variety of B. quadriguttata (Oliv.); but as I have no North-American specimens of

either species for examination I am unable to form au opinion on this point, and I am

inclined to believe that the two species in question are really distinct. The specimens

obtained by the late Mr. Morrison are all smaller in size than b. quadriguttata: they

have the thorax very finely (instead of distinctly and closely) punctured, but the punc-

tures are only visible under a strong lens; and the elytral strie regular and plainly

visible, and not obscured by very similar punctures on the interstices as in the allied

species (although Lacordaire does not mention a difference in this respect between the

two insects). The Guatemalan examples do not seem to differ in any important way

from the others, but they vary considerably in size amongst themselves.

4 (a). Babia distinguenda.

Subquadrate, black; pubescent below; thorax almost imperceptibly punctured; elytra rather strongly

_ punctate-striate, the interstices also distinctly punctured, a humeral and an apical spot reddish-fulvous.

Length 14-23 lines.

Hab. Mexico, El Cameron, Cordova (Sallé), Oaxaca (Hoge) ; Guatemaa, San Gero-

nimo (Champion), Las Mercedes (mus. Stuttgart).

This species is closely allied to B. quadriguttata, but differs from it as follows:—

The thorax is microscopically, but the elytra are much more strongly and closely,

punctured; and the anterior red spots of the latter are of a different shape, these

(instead of having their posterior margin rounded as in B. quadriguttata) being concave

BABIA. 83

behind and extending downwards a little distance along the lateral margin. In

B. distinguenda the head is either impunctate or extremely minutely punctured; the

antenne are dentate within from the fifth joint ; the thorax is at least twice as broad as

long (but agrees in shape with that of B. quadriguttata) ; and the elytra have so many

extra punctures placed between the more regular strie that the latter are difficult to

define, all the punctures being of nearly equal size, and also a shallow (but distinct)

transverse depression below the base. In the Sallé collection this species bears the

name of #. pudica, Lac., with which I cannot identify it; Lacordaire says (as above

remarked) that the humeral spot commences below (“sous ”’) the shoulder, and that

the punctuation of the elytra is scarcely visible, while, on the contrary, in the present

species it is more strongly impressed than usual. The fifteen specimens received from

the above localities agree very nearly with each other; in all, the humeral spot is

transversely-subquadrate in shape (extending to the basal and lateral, but not to the

sutural, margins), and its posterior margin concave.

4 (s). Babia amplicollis.

Babia amplicollis, Deyr. in litt.; Gemm. & Harold, Cat. Col. xii. p. 32987.

Oblong, widened posteriorly, black; thorax finely punctured, the sides narrowly flattened ; elytra finely

punctate-striate, a quadrate humeral and a round apical spot, flavous.

Length 2 lines.

Hab. Mexico!, La Parada, Toxpam, San Miguel (Sailé).

B. amplicollis although closely allied to B. guadriguttata seems to differ sufficiently

to justify its separation. It is much larger and more widened posteriorly. The thorax

is strongly transverse, and has a narrow but distinctly flattened and much rounded

lateral margin (which is not the case in PB. quadriguttata); and its surface is very

closely (though finely) punctured. The elytra have their anterior spots nearly square

(that is, their posterior margin, instead of being rounded, is slightly concave or

straight), the strize distinct, and between the first row and the suture a number of

labelled as above ; another, formerly in the collection of Sturm, is labelled B. consen-

tanea.

4 (c). Babia parvula.

Obscure fulvous below ; above black; head punctured near the eyes; thorax extremely finely punctured ;

elytra widened towards the middle, strongly punctate-striate, the interstices minutely punctured, a

subquadrate spot at the base of each, and the apex, rufous.

This very small species also seems to be closely allied to B. quadriguttata, but differs

from it in several particulars. The general shape of B. parvula is ovate and widened

posteriorly. ‘The head is distinctly impressed with rather elongate punctures near the

eyes ; the antenne extend to the base of the thorax and are black, with the exception

of the two or three basal joints, which are fulvous. The thorax agrees with that of

B. quadriguttata, and is finely and sparingly punctured. The elytra are, however,

quite different in shape and punctuation, the latter being much stronger and the

interstices also are punctured ; the humeral fulvous spot extends nearly to the suture

and is narrower at the base than at its extremity ; and the posterior spot is round and

placed at the extreme apex. The legs and under surface are more or less distinctly

fulvous. ‘The Guatemalan specimen differs from those from the State of Panama in

having the head impunctate, and the basal joint of the antennae and the legs black ;

but as I cannot find other differences, I treat it as a variety of the same species.

Babia costalis (p. 34).

To the locality Mexico, add :—Oaxaca (Sallé).

This species may be known from its allies by having only a single humeral fulvous

mark, the usual hinder spot being absent ; the thorax is more or less distinctly punc-

tured at the sides, nearly impunctate on the disc. The species seems to be rare, as I

have only seen two specimens as yet.

6. Babia mexicana.

Black ; the second and third joints of the antenne fulvous; head and thorax distinctly punctured ; elytra

strongly punctate-striate, the interstices subconvex, a quadrate humeral and an apical spot on each,

fulvous.

Length 14 lines.

Head closely and somewhat rugosely punctured ; antennz robust, the fourth and following joints transverse ;

thorax more than twice as broad as long, the sides but moderately deflexed, the lateral margins rounded,

the anterior margin moderately produced, the median lobe of the posterior margin scarcely produced and

straight, the surface rather closely and finely punctured ; elytra with a slight basal transverse depression,

regularly and strongly punctate-striate, the interstices each with a single row of smaller punctures and

slightly convex, the shoulders with a subquadrate small fulvous spot, the apex with a round one.

Hab. Mexico, Cuernavaca (Sailé).

B. mexicana may be known from any of the other species of the genus inhabiting our

region by the elytra being strongly punctate-striate and with the interstices also punc-

tured; the humeral spot is subquadrate in shape and occupies about half the width of

each elytron at the base. The four specimens received agree entirely with each other.

7. Babia chiriquensis. (Tab. XX XVII. fig. 9.)

Ovate, convex, black ; thorax transverse, impunctate; elytra convex, finely punctate-striate, reddish-fulvous,

a broad band across the middle (widened at the suture) black.

Length 2-23 lines.

Hab. Panama, Volcan de Chiriqui (Champion).

B. chiriquensis is a small species of rather convex and subcylindrical shape ; it

BABIA.—URODERA. 8)

exactly resembles Urodera crucifera, Lac., in the elytral pattern, except in the non-

prolongation of the black band along the suture. ‘The thorax is twice as broad as long ;

its anterior margin is strongly produced in front, but the posterior margin is nearly

straight at the sides and but feebly lobed (in which the species differs therefore from

the genus Urodera) ; the surface is entirely impunctate, and in some specimens of a

bronze tint; and the lateral margin is also impunctate (and not rugose, as is generally

the case). The broad black elytral band does not extend in some specimens to the

sides, and the anterior margin of this band is concave near the suture. ‘The prosternum

is extremely narrow. |

B. chiriquensis differs from B. distinguenda in the uninterrupted fulvous basal band

of the elytra, this band extending to the suture in the present species.

STEREOMA (p. 34).

Stereoma anchoralis (p. 34).

To the locality given, add :—Braziu (coll. Jacoby).

I think it is somewhat doubtful whether the locality, “ Mexico,” given by Lacordaire

is the true habitat of this species. Amongst the very large amount of material from

Central America I have had for examination, not a single example of this propor-

tionately large-sized insect has been found; some years ago, however, I received from

Herr F. Baden of Altona a single specimen answering perfectly to Lacordaire’s

description of the variety of S. anchoralis, and this was labelled ‘ Brazil.”

URODERA (p. 34).

Urodera crucifera (p. 35).

To the locality given, add :—-Mzxico, Ventanas in Durango, Monterey in Nuevo Leon,

Tacambaro, Huetamo in Michoacan, Chilpancingo, Iguala in Guerrero, Tapachula in

Chiapas (Hége), Oaxaca, Etla, Vera Cruz (Sallé), Cuernavaca (H. H. Smith), Temax in

North Yucatan (Gaumer); Nicaraeva, Chontales (Belt).

A long and careful examination of great numbers of specimens has convinced me

that no single character can be pointed out to distinguish with certainty U. crucifera

from U. chevrolati and U. hépfneri, Lac. ; and I much doubt whether the two latter are

‘anything more than varieties of the first-mentioned species. If the extreme forms

with differently-shaped thorax and elytral markings are placed side by side, they may

be supposed to represent distinct species; but an examination of the intermediate

varieties proves the inutility of separating them. Our examples vary to such a degree

that they might with equal propriety be referred to either of the three above-named

species described by Lacordaire; neither the more or less transversely-shaped thorax

nor the narrower or wider elytral band is a guide for specific separation. I provisionally

retain Lacordaire’s species as distinct; but the real specific limit of these insects can

only be satisfactorily settled by a study of their life-history.

86 PHYTOPHAGA.—-SUPPLEMENT.

Urodera hopfneri (p. 35).

According to Lacordaire the thorax of U. hépfneri is scarcely wider than long:

specimens with the thorax thus formed I have not seen, although nearly a hundred

from different localities in Mexico are before me. The Guatemalan examples in

Sallé’s collection labelled U. hépfneri I am unable to distinguish from U. crucifera.

Urodera chevrolati (p. 35).

To the locality Mexico, add:—Pinos Altos in Chihuahua (Buchan-Hepburn),

Ventanas in Durango (Hége), Almolonga (Flohr), Oaxaca, Cordova, Vera Cruz, Etla

(Sallé).

The specimens I provisionally refer to this species have the thorax more transversely

shaped than in U. crucifera, and the elytra fulvous, with a narrow oblique transverse

black band placed at the middle (this band being generally twice as wide as it is in

the examples I identify with U. crucifera); but the elytra are sometimes entirely

fulvous, or have each a small black lateral spot placed before the middle.

5. Urodera dilaticollis.

Black; thorax much broader than long, with flattened sides, impunctate; elytra fulvous, finely punctate-

striate, a central transverse band (angulate at the sides), and the margins narrowly, black.

Var, Elytra with a small black anterior spot.

Length 23-3 lines.

Somewhat widened posteriorly ; the head very shining and impunctate, with the exception of a few punctures

near the inner margin of the eyes ; antenne with the third joint fulvous, the other joints black; thorax

strongly transverse, the sides flattened and rounded, the median lobe moderately produced, the surface

very shining and impunctate; scutellum rather broader than long; elytra narrowed at the base,

extremely finely punctate-striate, fulvous, narrowly margined with black, and with a narrow transverse

black band at the middle, this band widened at the suture and laterally angulate.

Hab. Mexico, Santa Clara in Chihuahua, Refugio in Durango (Hége).

Five specimens. U. dilaticollis might at first sight easily be mistaken for U. cruci-

Sera or U. chevrolati; but it differs very considerably from both in the shape of the

thorax and elytra. The thorax in the present insect is very shining and smooth,

without trace of punctures, and only the flattened sides show the usual fine rugosities ;

it has the sides rounded and flattened to a much greater degree than in any of our

numerous examples of the two above-named allied species ; in these latter its sides do

not project beyond the elytra. ‘The elytra are distinctly narrowed at the base, giving a

posteriorly widened shape to the insect (in opposition to the more narrowed appearance

of U. crucifera) ; and the band, instead of being straight as in U. crucéfera, is angulate

at the sides. In the variety, which was obtained at Refugio, the elytral band is

replaced by a small black spot; but the structure of the thorax and of the elytra agrees

exactly with that of the typical form. Babia undabunda, Lac., seems to agree in the

markings of the elytra with U. dilaticollis; but Lacordaire does not mention the shape

of the thorax in that species, which, moreover, inhabits Brazil.

Hab. Guatemaua, San Gerénimo ( Champion); Panama (Boucard).—CotomBta }.

The single specimen from Guatemala agrees well with the author’s description, and

with examples from Colombia contained in my own collection. In the Guatemalan

specimen the thorax is scarcely one half broader than long, finely and closely punc-

tured, and has two distinct oblique depressions close to the basal lobe; the elytra are

rather strongly punctate-striate, with a transverse almost regular red basal band (not

extending to the suture) and a similarly-coloured small apical spot; the tibie are

short, strongly dilated, and with an acutely raised lateral and frontal ridge; and the

first joint of the anterior tarsi is greatly widened in the male.

Two specimens obtained by M. Boucard at Panama also agree with Lacordaire’s

description of U. quadrisignata.

7. Urodera inflata (2),

Hab. Panama (Boucard).—Co.omsra },

It is with some doubt that I refer our Panama specimen to U. inflata, so many

closely allied forms (some of which are probably mere varieties) having been described.

This example differs from the two from the same locality referred by me to U. quadri-

signata, in having a broader thorax (though agreeing in the punctuation), and in the

red basal band of the elytra being connected with a similarly-coloured narrow lateral

band which extends quite to the sutural angle. The first-mentioned specimen agrees

well with Lacordaire’s description of U. inflata; the two others may represent a variety

of the same species.

SAXINIS (p. 36).

The members of this genus seem to vary amongst themselves to a very great degree,

scarcely two specimens agreeing perfectly with each other ; and the true limits of the

species are at present, I think, very unsatisfactory and doubtful. The division into

two sections, as adopted by Lacordaire, of the species with a rounded and the species

with a subangulate lateral lobe of the elytra does not give much assistance, as there

are several others that are intermediate in this respect. Hach sex seems again subject

to considerable variation. |

‘Saxinis basilaris (p. 36).

To the Mexican locality given, add:—Oaxaca (H6ge).

The specimens which I refer to this species agree in the punctuation of the thorax

88. PHYTOPHAGA.—SUPPLEMENT.

with Lacordaire’s description, these having the middle of the disc very finely and

sparingly punctured, the reverse being the case in most of the allied species. Here

again, as in many other instances, the shape of the thorax as given by the author

seems to be incorrect. The thorax in S. basilaris is described as about one third

broader than long ; in our specimens it is twice as broad as long (which indeed is the

shape of the thorax of most of the species of Sawinis, if the width of the base is

compared with the greatest length across the middle). The elytra in our insect are

rather strongly and regularly punctate-striate, the punctuation becoming finer towards

the apex and the punctures themselves being somewhat transverse in shape, and there

are traces of transverse wrinkles near the base (I cannot say, however, that the inter-

stices are finely alutaceous as given by Lacordaire—they are, on the contrary, shining

and with a few fine punctures here and there). In our specimen from Orizaba the

humeral spot extends to half the length of the elytra; in those from Oaxaca this spot

is shorter (in one specimen, however, extending much nearer to the suture than in the

other). In the Sallé collection the name of S. dasilaris is attached to the Orizaba

specimen, but, as may be seen, all doubt is not removed as to the proper identification

of the species.

Saxinis quadrina (p. 36).

To the localities given, add :—GuatemaLa, Duefias (Champion), Zapote (mus. Stutt-

gart).

A specimen of this species labelled in Lacordaire’s handwriting is contained in the

British Museum; I am therefore enabled to give a more detailed description of

S. quadrina after having carefully compared the specimens from the above localities.

These examples are all of a very dark bronze colour or entirely black (like the variety

mentioned by the author), The thorax is stated by Lacordaire to be scarcely broader

than long, but this only applies to the male insect, the female having a considerably

broader thorax ; the disc in both sexes is very finely and not very closely punctured,

the punctuation becoming, however, very close at the sides. The elytra may be

described as rather regularly punctate-striate, the striz consisting of single rows of

punctures which diminish gradually in size towards the apex; the interstices are more

or less convex (but not strongly so) and impunctate ; and the red humeral mark is of

nearly quadrate shape, with its posterior margin perfectly straight. S. guadrina varies

from 14—23 lines in length.

2 (a). Saxinis sonorensis. (Tab. XX XVII. fig. 10.)

Bluish-green ; head rugosely punctured; thorax closely and distinctly punctate; elytra closely punctate-

striate, the interstices more finely punctured, the shoulders with a rounded reddish-fulvous spot.

Length 13-2 lines.

Head very closely punctured, with longitudinal raised strige ; antenne with the joints transverse from the

fourth outwardly, the basal joint metallic bluish, the third joint fulvous ; thorax one third broader than

long in the male, distinctly broader in the female, very closely and distinctly punctured on the disc, a

little more strongly but less closely so at the sides, the anterior margin strongly produced at the middle ;

elytra with closely approached rows of rather deep punctures, the interstices also closely and finely

punctured and more or less transversely rugose. .

Hab. Mexico, Northern Sonora (Morrison), Juquila, Oaxaca, La Parada (Sal/é).

I cannot treat S. sonorensis as a variety of S. guadrina or refer it to any of the

species described by Lacordaire, the fifteen specimens received being constant in the

above-mentioned particulars. The insect averages larger in size than S. guadrina, and

is of a bluish-green colour. The thorax instead of being very finely and rather

remotely punctured is very closely and much more strongly punctate on the disc.

The elytra are very differently punctured to those of S. guadrina, the punctures being

so closely arranged below each other as to form almost continuous striz, and the inter-

stices are also closely but finely punctured ; and the humeral spot (which in S. guadrina

is quadrate) has its posterior margin rounded—it extends inwards to half the width

and downwards to not quite half the elytral length. A certain number of specimens,

also obtained in Northern Sonora, differ from the type in the much less closely

punctured thorax, and in the rather smaller red humeral spot; but I cannot find any

other characters of importance by which to separate them (they may still be distin-

guished from S. guadrina by the dark bluish or greenish colour, and the punctuation

of the elytra and their more rounded red spot). The other Mexican examples agree in

the punctuation of the thorax and in that of the elytra, but they differ in the form of

the humeral spot (this being shaped as in S. quadrina) ; it is therefore impossible

to say with certainty whether these specimens represent another closely allied species

or a variety of S. sonorensis, the latter being the most probable.

2 (s). Saxinis irregularis.

Metallic dark blue; thorax shining, rather remotely punctured; elytra strongly and irregularly punctured

anteriorly, each with a subquadrate fulvous humeral spot.

Length 14 line.

Hab. Mexico, Ciudad in Durango (Forrer).

The thorax in this species is not closely and rather evenly punctured throughout,

very shining, and of a metallic dark blue colour; it is about one half broader than

long, but more transverse in the female. The scutellum is closely and strongly

punctured. The elytra are very strongly and closely punctured, the punctures being

all of similar size and not intermixed with smaller ones and scarcely showing a trace of

a linear arrangement ; this punctuation extends also to the fulvous humeral spot, the

latter being similar in shape to that of S. guadrina. S. irregularis is therefore

principally distinguished amongst its allies by the punctuation of the thorax being remote

and that of the elytra irregular ; in most of its congeners the thorax is more closely

punctured at the sides than on the disc, which in the present insect is not the case.

This is the largest species of the genus and it has the lateral lobe of the elytra

distinctly angulate; the elytra themselves are very deeply but not very regularly

punctate-striate. According to Dr. Horn, 8. sawcia, Leconte, is synonymous with the

present insect. |

8 (a). Saxinis hogei. (Tab. XXXVII. fig. 11.)

Metallic greenish-blue ; antenne black; head closely punctured; thorax closely and strongly punctured at

the sides; elytra very strongly punctate-striate, the interstices impunctate and rather convex, a sub-

quadrate spot on the shoulders rufous. .

Length 13-2 lines.

Of somewhat posteriorly narrowed shape, the. head closely and strongly rugose-punctate, the vertex strigose,

the labrum and palpi black; antenn not quite extending to the base of the thorax, black, the second

and third joints obscure fulvous ; thorax twice as broad as long, the sides but slightly rounded, the disc

remotely, the sides closely and strongly, punctured ; scutellum deeply punctured ; elytra flattened, but not

visibly depressed below the base, very deeply and closely punctate-striate, the interstices smooth and

shining, subcostate, the lateral lobe rather rounded and moderately produced, the shoulders with the usual

subquadrate fulvous or rufous spot.

Hab. Mexico, Ventanas in Durango, Tupataro in Guanajuato (Hoge), Amula and

Xucumanatlan in Guerrero (Smith).

In its metallic-blue colour S. hégei most nearly resembles S. sonorensis, though

differing from that insect and most of its allies in the impunctate and rather convex:

interstices of the elytra. SS. saginata is a very closely allied species, but is larger and

more robust. The numerous examples obtained all agree in the above particulars, and

although they may possibly represent only a small variety of S. saginata, I must

consider them at present as distinct, no intermediate specimens having come under my

notice.

6. Saxinis hirtipennis.

Dark greenish-blue ; head strigose-punctate; thorax shining, closely punctured at the sides; elytra more

opaque, closely punctate-striate and clothed with short pubescence, each with a subquadrate fulvous

humeral spot; below densely pubescent.

Of broad and flattened shape, metallic greenish-blue, the head very closely longitudinally strigose and finely

punctured, the eyes reniform; antenne extending to the base of the thorax, black, the basal joint obscure

metallic blue, the third joint slender and more elongate, the following joints strongly transverse; thorax

twice as broad as long, the sides evenly and strongly rounded, the anterior angles produced into a blunt

point, the surface transversely convex, very deeply and closely punctured at the sides, more remotely and

finely so on the disc; scutellum strongly and closely punctured ; elytra slightly depressed below the

scutellum, flattened on the disc, distinctly and regularly, but not very strongly, punctate-striate, the

cence, the shoulders occupied by a subquadrate fulvous spot extending inwards to the sixth row of

occasionally. In every other particular the Panama specimens agree with those from

Guatemala. MW. basilaris, Suffr., from Colombia, seems to be very closely allied to

M. bimaculatus, but to differ, according to the description, in the absence of punctua-

tion below the middle of the elytra, which, on the contrary, is very distinct to the

apex in WZ. bimaculalus.

T have already remarked that Central-American specimens are somewhat doubtfully

referred to M. nigritulus, Suffr.; they agree with the description of the author,

however, in the main points, but they have the elytra more strongly punctured.

In the male insect the entire head, with the exception of the vertex, and the apices

of the tibize and the tarsi are fulvous; in the female the head is bluish-black, the

labrum only being fulvous; and the colour of the prosternum seems to vary in the

different sexes in the same way. In any case, the differences between’ the Central-

American and the Brazilian examples seem to me to be of too slight a character to

justify their separation. Specimens from San Gerénimo differ in having the antenne

almost entirely fulvous and the elytra more strongly punctured ; but these details vary

in the different individuals.

Herr Hoge obtained about twenty specimens of this species during his second expe-

dition. MM. sculptilis may be known from the allied forms by its entirely opaque upper

surface, this part being of a very dark bluish colour; the elytra, which are strongly

punctured to the apex and have the interstices at the sides strongly convex, differ

further from those of other similarly-coloured species in the more strongly transversely

rugose and minutely punctured spaces between the punctures; the legs and antenne

are entirely black, with the exception of the basal two joints of the latter, which are

fulvous ; the underside is black, with a slight greenish tint; and the prosternum is

finely punctured and much broader than long.

The thirty specimens obtained by Mr. Champion at the above localities agree almost

entirely with the description given by Suffrian of Fabricius’s species, with the exception

of the colour of the head; the latter in all the Panama specimens is (as Fabricius

states) fulvous like the thorax, instead of blue as described by Suffrian. I cannot,

however, find the slightest difference in any other respect between the Panama speci-

mens and Suffrian’s description of M. bicolor; and it is probable that specimens

occasionally occur in which the head is bluish instead of fulvous.

13. Monachus panamensis.

Hab. Panama, Bugaba, David (Champion).

This small species is no doubt closely allied to M. gemellus, Suffr., and M. bicolor

other Monachus described by Suffrian. The head above is generally bluish-black, and

the lower part more or less fulvous (in one specimen the entire head is fulvous); the

94 PHYTOPHAGA.—SUPPLEMENT.

antenne, which extend to the base of the thorax, have their terminal joints gradually

thickened, and are black, with the basal two or three joints generally fulvous. The

thorax is fulvous and opaque, strongly transverse, and (when viewed under a strong

lens) closely covered with minute punctures, the extreme posterior margin having, as"

usual, a deeper row of punctures, the margin itself being black. The elytra are dis- -

tinctly narrowed at the apex, strongly punctate-striate, and blackish-green or bluish in

colour; the striae commence at a little distance below the base and the punctures

compdsing them gradually become smaller towards the apex; the interstices are

extremely finely wrinkled and punctured, and the ninth is distinctly convex. The

underside is black, with the exception of the prosternum, the latter being stained

with fulvous. The legs are black, the tibie slightly stained with fulvous.

M. panamensis differs therefore from M. gemellus in the black colour of its upper

surface, in the absence of the spots on the thorax, and in the fulvous prosternum and

almost black legs. The nearly black colour of the elytra, the punctuation of the thorax,

and the fulvous prosternum separate the species from WV. bicolor (Fabr.). Suffrian,

who described the last-named species at length, says nothing about the sculpture of

the thorax; but he certainly would have mentioned the colour of the prosternum if it

differed from that of the rest of the underside. The seven specimens obtained agree in

all the above details.

14. Monachus puncticollis,

opaque reddish-fulvous colour, and closely covered with deep punctures at the middle of the disc and near

men obtained is a male; nevertheless, the differences shown between this specimen and

the female of MZ. puncticollis do not seem to me to be sexual. In the present insect,

which is much smaller and more parallel than M. puncticollis, the head is obscure

piceous ; the antenne are black, with the exception of the basal four joints, these latter

being fulvous; the thorax is of the same shape and sculpture as in M. puncticollis,

although the punctures are proportionately finer, but the elytra are differently punctured,

the punctuation being very distinct to below the middle, and the interstices are not

finely granulate but shining; and the prosternum is black (instead of fulvous) and not

so transverse. In this genus the female insect is, asa rule, more strongly sculptured

than the male, and I believe, therefore, that M. semiviridis is really distinct from

MM. puncticollis.

This is the smallest species of Monachus known to me from our region, and it agrees

in every respect with Suffrian’s description; the general colour of the insect is pale

flavous. Numerous examples were captured by Mr. Champion.

17. Monachus simplex.

Fulvous; antenne (the basal joints excepted) black; thorax finely but distinctly punctured ; elytra very finely

punctate-striate, the punctures strongly impressed at the base, fulvous, the extreme basal margin blackish ;

tarsi piceous.

The nearest allied species to VU. simplex is apparently J. sordidulus, Suffr., which

is, however, a much smaller insect, being one of the smallest of the genus, and differs

also in several other details. /. simplex may be known by its unicolorous fulvous

upper and under sides. ‘The basal three or four joints of the antenne are of the same

colour, the other joints being black and distinctly thickened. The thorax is at least twice

as broad as long, but rather strongly narrowed in front, the sides slightly rounded ; the

surface is somewhat closely impressed with rather elongate punctures, the interstices

being minutely granulate; and the basal margin is furnished with the usual deeper

row of punctures. The elytra are narrowed towards the apex; the punctures are

strongly impressed immediately below the base only, the punctuation becoming very

fine beyond and disappearing altogether near the apex; the colour, like that of the

thorax, is fulvous, with the exception of the extreme basal margin, the latter being

nearly black. The pygidium is finely and closely punctured and also fulvous. The

underside shows scarcely any trace of punctuation; the prosternum is nearly twice as

broad as long. ‘The tarsi are more or less piceous. A single specimen from Chontales

does not seem to differ from the others, except in the breast and the anterior portion of

the abdomen being black, which may probably be due to local variation.

18. Monachus longicornis.

Piceous or black, the head, antennz, thorax, and legs fulvous or flavous ; antenne proportionately long ;

elytra piceous or black, strongly punctate-striate.

Length ? line.

Hab. Panama, Bugaba, David (Champion).

In this small species the antenne are long and entirely fulvous, and in the male

insect extend to beyond the middle of the elytra; the head is flavous and impunctate,

and the eyes nearly meet at the vertex; the thorax is fulvous and entirely impunctate,

about twice as broad as long, and has the anterior and lateral margins sometimes very

narrowly pale flavous; the scutellum is narrowly elongate and raised; the elytra are

more or less dark piceous or entirely black, strongly and regularly punctate-striate, the

punctures visible to the apex, with the interstices more or less swollen posteriorly and

at the sides; and the legs and prosternum are entirely fulvous, the latter being broader

than long. The four specimens before me differ but little from each other ; but in one

the terminal joints of the antenne are stained with fuscous. The length of these organs

will distinguish M. longicornis from any similarly-coloured species here enumerated

from our region.

19. Monachus teapensis.

Black, the head, the basal joints of the antenne, the sides of the thorax, and the tarsi fulvous; thorax impunc-

tate, opaque; elytra finely punctate-striate, the outer interstice convex.

Var. Head and elytra obscure bluish.

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

I cannot identify this insect, of which very many specimens have been received,

with any of the species described by Suffrian, although it is no doubt very closely

allied to several of them, in particular to M. nigritulus and MW. scrobiculatus. It will

suffice, therefore, to point out the differences:—In most specimens of J. teapensis

the head is fulvous, but in some it is bluish-black, the labrum, however, always remain-

ing fulvous ; the antenne have their basal two or three joints fulvous, the others being

MONACHUS. 97

black ; the thorax has no trace of punctuation, even when seen under a very strong

lens, and the middle portion of the disc is occupied by a larger or smaller black patch

which sometimes extends nearly to the lateral margins, and there is no row of deep punc-

tures to be seen at the posterior margin (this being very distinct in several closely-allied

species); the elytra are generally black, sometimes bluish, with prominent shoulders,

and they are strongly and regularly punctate-striate, the punctures, although becoming

gradually finer posteriorly, being distinct to the apex, the ninth row consisting of larger

punctures, and the following space distinctly raised; the underside and legs are

black, but the anterior femora (as wellas the base of the two other pairs) are frequently,

and the tarsi entirely, fulvous.

If this description is compared with those given by Suffrian of several closely allied

forms, it will be seen that I. teapensis differs either in coloration or sculpture from

any of them. J. orbicularis, from Caracas, has a finely punctured thorax, and WM.

obscurellus and M. scrobiculatus have yellow legs. In M. nigritulus (the thorax of

which is not marked with flavous at the sides), as well as in J. umbrosus, the punctua-

tion becomes obsolete towards the apex of the elytra. _

About 100 examples of /. teapensis have been received, all from the Mexican State

of Tabasco.

20. Monachus elegans.

Black, the head, abdomen, and pygidium flavous; elytra with a broad triangular basal band, narrowed at the

suture, red. .

Var. Thorax with tke anterior and lateral margins narrowly fulvous; elytra red, with a transverse black band

below the middle.

Length 14-18 lines.

Hab. Panama, Volcan de Chiriqui, Caldera, David (Champion).

Closely allied to WM. bimaculatus, but differing in the following particulars :—The

head (in most specimens) is entirely flavous, and the eyes in the male insect meet at

the top of the vertex ; the elytra are similarly punctured, but their anterior half is

occupied by a red transverse band which greatly narrows towards the suture, though

extending to it. The fulvous portion of the abdomen seems to vary in extent; the

pygidium, however, is always of that colour. In the variety the anterior and lateral

margins of the thorax are also narrowly fulvous, and the red colour of the elytra pre-

dominates, it being interrupted behind the middle by an irregular transverse black

band which extends narrowly upwards along the suture to the base. M. elegans also

differs from WV. bimaculatus in its larger size, and in the more transversely shaped

and less conical thorax. All the specimens agree in having the large red basal band

of the elytra extending quite to the suture.

I can only refer doubtfully the three specimens from Central America to Suffrian’s

species, as they agree in the principal points with his description; but they also show

some differences amongst themselves. The general colour of the upper and undersides

is fulvous, the legs also being of this colour in one specimen, in the others the latter

are piceous. The thorax in the San José example has two small piceous spots (as in

the type); in the others these spots are wanting, and the punctuation is scarcely, if at

all, visible. The elytra have the base narrowly margined with piceous, this colour in

one specimen extending downwards fora short distance along the suture ; the punctures

are finer posteriorly, but they do not disappear (as stated by Suffrian). It will be seen,

therefore, that without more specimens for comparison it would be inadvisable to

describe the present insect as new.

CRYPTOCEPHALUS (p. 42).

In this as in so many other genera of Phytophaga, the separation of specimens into

species is very often connected with insuperable difficulties, these insects being subject

to great variation ; and there is little doubt that many of the species at present regarded

as distinct will be found to be mere varieties. Even the punctuation of the elytra, a

character used by Suffrian to divide the species into a large number of groups, offers

no certain guide ; for example, in the same species the transverse smooth space which

frequently interrupts the lateral striz behind the shoulders is present in one, and absent

in another specimen, while the strize themselves do not always run in the same direction

in the different individuals. Leeonte has briefly described many North-American

species; but short diagnoses in the Cryptocephalide, a family represented by so many

closely-allied species, even in the same localities, are of no assistance to a monographer,

and it is therefore quite possible that some of the species treated as new in this work

may prove to be identical with some already described. ‘here are, however, I believe,

but few species common to North America and our region, and I have, as far as pos-

sible, avoided describing from single or doubtful specimens. Very many additional

species have now to be added to our list.

‘Cryptocephalus abruptus (p. 42).

I refer two specimens from the above localities to C. abruptus. C. maculipennis,

Suffr., is very probably a variety of this species; it seems only to differ from it in

having the elytral bands broken up into spots. Both insects were obtained at

Tupataro. Suffrian says nothing about the punctuation of the elytra being arranged in

pairs, a character common to both C. abruptus and C. maculipennis, between which the

brown bands are placed; the latter are, without doubt, subject to interruption in

various ways.

Cryptocephalus alternans (p. 42).

To the locality Mexico, add :—Near the city, Tupataro in Guanajuato (Hége).

The two specimens obtained by Herr Hoge agree very closely with Suffrian’s

description, and only differ from it in having the sixth and seventh rows of punctures

(which according to Suffrian are entirely wanting) indicated by some impressions

below the shoulder ; the short sixth row is united, however, below the shoulder with

the seventh in a hook-like manner, In one specimen the three elytral stripes are

strongly marked and black; in the other they are only indistinctly indicated,-so that

the punctures between which the stripes are placed are here more distinct and blacker

than the interstices ; in the last-mentioned example the formation of the sixth row of

punctures is especially plain, it being obscured in the other by the black colour. The

thorax is proportionately very short, and is better described as yellow, with a V-shaped

central black mark. The specimen from Tupataro also has a small black spot placed

near the lateral margin of the thorax (thus agreeing with Suffrian’s description); in the

other this spot is enlarged into a hook-like transverse line which divides the yellow colour

of the sides. The underside and legs also vary in the amount of black and yellow.

Cryptocephalus flavonotatus (p. 43).

To the locality Mexico, add:—Ventanas and Ciudad in Durango (Hoge).

I refer the three specimens obtained in the State of Durango to this species; they

might, however, be almost equally well referred to C. circumflezus, Suffr., which is

probably nothing more than a variety of C. flavonotatus. The Ventanas specimens

are large-sized insects (34 lines) and agree with the description of the author, with

the exception of the colour of the legs, the femora in our examples being yellow with

a brown central spot (not yellow with paler knees), The elytra are deeply punctured,

and have three transverse dentate brown bands (more plainly visible when seen without

alens). The male insect is unknown to me; Suffrian also only speaks of the female.

The example obtained at Ciudad differs considerably from the Ventanas specimens in

having the head and thorax entirely dark brown without yellow markings ;

; it also has

the thorax shorter and narrower, but similarly punctured, and the elytra marked

more irregularly placed and difficult to trace, although the general arrangement is

indicated as in the typical form.

6 (4). Cryptocephalus difficilis, (Tab. XX XVII. fig. 14, 2.)

Dark or yellowish-brown ; antenne (the basal joints excepted) black ; thorax smooth (¢), or finely punctured

( 9’), the margins and two spots at the base bright yellow ; elytra deeply punctate-striate, flavous, with

three broad transverse brown bands.

Length 2 lines.

Hab. Mexico, Las Vigas (Hége).

Of this species, which is doubtless closely allied to C. flavonotatus, if not a variety

of that insect, two specimens were obtained by Herr Hoge during his second expedi-

tion. The ground-colour in the male is bright flavous. The head is finely and

sparingly punctured, its middle portion, as well as the disc of the labrum, dark brown ;

the antenne are nearly black, with the two basal joints dark fulvous. The thorax is

about twice as broad as long, rather strongly narrowed in front, with long and acutely-

pointed posterior angles; the surface is shining and scarcely visibly punctured in the

male, more distinctly so in the female; the dark brown colour of the disc is interrupted

by the narrow anterior and the broadly lateral flavous margins and at the base by two

narrow and widely-separated oblique flavous spots which are connected by the narrow

similarly-coloured portion of the posterior margin. The elytra have the transverse brown

bands much more pronounced than they are in C. flavonotatus ; the punctures are not

so closely placed, and the interstices are much flatter; the fifth row (which in C. flavo-

notatus forms an acute angle below the middle, and is joined at that place to the

posterior end of the sixth row) is in part broken up and irregularly arranged, the punc-

tures being placed in two rows (indicating the fifth and sixth rows), but is continued

anteriorly to the shoulder; the seventh and eighth rows, which are joined at the apex

(as in C flavonotatus), form each below the middle a short transverse angle, and enclose

between them a smooth, slightly raised transverse space, immediately above which there

is another similar transverse space. The underside of the male is much lighter in

colour than that of the female, the latter also having the legs entirely brown, the

femora in the other sex being marked with a yellow spot at the base. C. difficilis

differs, therefore, from C. flavonotatus in the thorax being less closely punctured and

more shining, and in having the brown and yellow colours sharply divided, and also

in the different system of punctuation of the elytra. ‘The female insect is figured.

6 (3). Cryptocephalus dissolutus.

Pale flavous or fulvous, the terminal joints of the antenne black; thorax extremely finely punctured, flavous,

a lozenge-shaped spot at the middle, fulvous ; elytra flavous, a transverse band at the base, two spots

below the middle and one at the apex, dark brown.

102 PHYTOPHAGA.—SUPPLEMENT.

C. dissolutus closely resembles C. flavonotatus, and, to a less degree, C. difficilis ; it

seems, however, to differ sufficiently from both to justify its separation, if characters

derived from colour and elytral punctuation are considered of any specific value. It

will be sufficient to point out the differences between the present and the allied species:—

In C. dissolutus the thorax is nearly impunctate on the disc, and has a fulvous lozenge-

shaped spot (this spot in the Guatemalan specimen is almost obsolete). The elytra

have only two bands (each broken up into two spots), and a small spot at the apex

placed between the third and fourth, and the seventh and eighth rows ; these rows

are, as usual, connected posteriorly, as are also the shorter fifth and sixth ; the seventh

and eighth rows are only distinct anteriorly near the shoulder, and below this they are

connected by a few transversely placed punctures which surround a smooth transverse

space. The underside and legs are entirely fulvous. Two specimens, both females.

6 (c). Cryptocephalus separatus.

Obscure flavous, the antenne (the basal joints excepted) black; thorax impunctate ; elytra flavous, strongly

punctate-striate, the stric not interrupted by a raised space, a spot on the shoulder, an angular transverse

band at the base, another band below the middle, and a spot at the apex, dark brown.

Length 23 lines.

2. Head depressed, finely punctured, the middle stained with fulvous; antenne two thirds the length of the

body, black, the lower four joints fulvous; thorax twice as broad as long, widened at the middle,

the sides rounded, the surface entirely impunctate, obscure flavous ; scutellum flavous, its apex truncate ;

elytra robust, cylindrical and parallel, the punctured strie strong and regular, the fifth and sixth rows

abbreviated and connected before the apex, the seventh row represented anteriorly by a few remotely-

placed punctures only, but complete posteriorly, and there joined to the eighth row, the interstices

finely transversely rugose, the ground-colour flavous (brighter than that of the thorax), the extreme

basal margin black, a spot on the shoulder, a transverse band of angulate shape at the base, a similarly

shaped band below the middle extending to the lateral margin, an obscure spot at the junction of the

strie near the apex, and the extreme lateral margin posteriorly, dark brown; underside obscure flavous,

the breast darker and clothed with yellowish hairs ; legs obscure fulvous.

Hab. Mexico, Xucumanatlan in Guerrero (ZZ. H. Smith).

C. separatus somewhat resembles C. sordidus in coloration, but differs from that

species in having the dark bands of the elytra strongly marked, and their punctuation

finer and differently arranged ; there is an entire absence of a transversely raised space

and the rows of punctures are nearly all distinct. C. dissolutus is a still more closely

allied species of almost exactly similar markings, but that insect has the lateral rows

of punctures on the elytra interrupted by a comparatively broad impunctate space, and

the interspaces smooth (not finely rugose); it is, however, possible that C. separatus

may only be a local form of C. dissolutus. <A single female example, captured in July

CRYPTOCEPHALUS. .. ~ 103

-.It.seems to me almost impossible to refer with certainty several species with nearly

similar and equally variable elytral pattern to either of those described by Suffrian,

notwithstanding the large amount of material now available for examination. The

descriptions of C. plagiatus, C. patheticus, and C. rhombeus, Suffr., agree only partially

with some of the Central-American specimens; and, if the necessary allowance is

made for variation, our examples might equally well be referred to either of them. In

C. plagiatus, for example, to which I refer the specimens from the above-mentioned

localities, the thorax is described as black, with yellow interrupted anterior and

lateral margins, and two similarly-coloured basal spots. -In our specimens, however,

the anterior margin of the thorax is entirely yellow and not interrupted ; and the

elytra, instead of having eight, have only seven yellow spots (the small basal spot on

the lateral margin being connected with the large one below it), and the spot near the

scutellum (which is described as being the largest of the three) is in several examples

the smallest. As our insect agrees in its other characters with Suffrian’s description,

I prefer to point out these differences, and to look upon them as varietal rather than

specific.

10 (a). Cryptocephalus godmani.

Black ; the head, the anterior and lateral margins of the thorax, as well as two spots at the base of the

-latter, yellow ; elytra black, each with seven or eight more or less interrupted yellow spots, deeply punctate-

striate, the punctures interrupted laterally ; legs spotted with black and yellow.

Length 13 -14 i lines.

Head bright yellow, with a central longitudinal and sparingly punctured black stripe, the rest of the surface

impunctate ; labrum and mandibles obscure piceous ; antenne as long as the body, black, the lower five

joints fulvous ; thorax more than twice as broad as long, the sides nearly straight, and narrowed in front

the surface entirely impunctate, black, the anterior margin narrowly, the anterior and posterior angles

broadly, a central short stripe anteriorly, and two oblique spots at the base (sometimes preceded by

two other small yellow spots), yellow; scutellum black; elytra cylindrical, strongly punctate-striate, the

fifth to the eighth rows interrupted anteriorly and posteriorly by several transverse smooth and raised

spaces, an elongate spot near the scutellum, an angular narrow stripe at the middle of the base, the lateral

margin to the middle, the raised transverse spaces, and three spots placed triangularly (the two upper

ones each consisting of three e'ongate short stripes, separated by the black punctures, and the hinder one

transversely shaped and composed of two markings) near the apex, bright yellow; below black, the

anterior coxw, the prosternum, and a quadrate spot at the base of the first ventral segment, yellow ; legs

dark fulvous, the apex of the femora with a yellow spot margined with black ; pygidium black, with two

yellow spots.

Hab. Muxico, Omilteme and “Chilpancingo j in Guerrero (fH. H. Smith).

- C. godmani is no doubt somewhat closely allied to C. plagiatus, Suffr., but shows, I

think, sufficient differences to be considered distinct. The black disc of the thorax is

divided anteriorly by a narrow yellow stripe, which is connected with the similarly-

coloured anterior margin. ‘The elytra are more deeply punctured, and the rows at the

sides are interrupted by three, partly united, trausverse raised spaces, which form the

largest of the yellow spots; these latter are also differently shaped to those of

C. plagiatus ; and the lateral margin is yellow from the base to the middle. The

femora have a yellow spot margined with black near the apex. The three specimens

lately received agree in these particulars in both sexes.

Cryptocephalus patheticus (p. 45). (Tab, Il. fig. 17.)

To the localities given, add :—GvaTEMALa, Zapote, Guatemala city, San Gerénimo,

Chacoj (Champion), Chinautla (Salvin), Llano grande (mus. Stuttgart); PanaMa,

Bugaba (Champion).

As already remarked on p. 45 this species is subject to great variation, and it cannot

be separated from C. ocellatus by its colour only; the elytra have a few or many yellow

spots which are arranged as in C. plagiatus and C. 14-pustulatus. C. patheticus may,

however, be distinguished by the punctured strie being interrupted laterally, and

separated by a transverse smooth space, a character peculiar to many species of Crypto-

cephalus. The thorax seems invariably to have the sides marked with flavous and the

two basal spots more or less plainly visible; but the underside varies from black or

partially black to flavous. A single specimen from Bugaba, which I refer somewhat

doubtfully to C. patheticus, has the thorax dark brown, with two lateral subquadrate

yellow spots, and the two usual ones at the base very strongly marked, and the elytra

with eight well-developed spots.

By an oversight the reference to the Plate was omitted on p. 45. The Guatemalan

examples referred by me to C. rhombeus (p. 52) prove to belong to this species.

11 (a). Cryptocephalus affinis.

Flavous; thorax impunctate, fulvous, the sides and spots at the base obscure flavous ; elytra strongly punctate-

striate, with a transverse lateral smooth space, each with eight large flavous spots (3.2.2.1) divided by

dark brown narrow bands. |

Var. The elytral dark bands only indicated by short markings.

Length 1-2 lines.

Hab. Mzxico, Iguala, Acapulco (Zége), Tepetlapa in Guerrero (H. H. Smith) ;

Guatema.a, Chacoj in Vera Paz (Champion).

At first sight, C. affinis seems only to be a colour-variety of C. patheticus; but as

all the specimens of both sexes obtained by Herr Hoge agree with each other in the

following details, I am obliged to separate them from C. patheticus and C. plagiatus.

The head is flavous, with the usual darker central line at the vertex, and nearly

impunctate; the antenne extend to beyond the middle of the elytra, and have their

basal six joints fulvous, the others darker. The thorax is quite impunctate, in the

male scarcely twice as broad as long, and has the sides strongly deflexed ; the posterior

angles are acute, but not prolonged ; the disc is darker or paler fulvous, with a trace

of the usual lighter margins and basal spots; and the posterior margin is narrowly

edged with black. The elytra in the well-marked specimens have similarly-placed

and the same number of spots as in the allied forms; the eighth row of punctures.

CRYPTOCEPHALUS. 105

forms an angle before the middle and is connected with the fifth row, above which a

narrow transverse space is bounded by a similar transverse row of punctures connecting

the commencement of the sixth and seventh rows. These last-mentioned characters

are nearly the same as in C. patheticus; but in the present insect there are no black

markings on the underside or on the pygidium, these parts in all the specimens being

entirely fulvous. The elytral markings are better defined in some examples, the others

having only a few darker spots in place of the bands; the interstices are apparently

more convex in the male than in the female. Specimens of the last-mentioned sex

from Iguala are twice the size of the males from Acapulco, and are of a bright flavous

colour. <A single example from Guatemala is apparently referable to the same species.

11 (8). Cryptocephalus testudineus.

Flavous or fulvous; antenne as long as the body, black, the basal joints fulvous ; thorax impunctate, the sides

and two obscure spots at the base yellowish; elytra with eight large flavous spots divided by narrow

fulvous bands, the interstices more or less convex. ,

Length 14 line.

Hab. Mexico, Oaxaca (Hége); GUATEMALA, near the city (Champion), Coban in Vera

Paz (Conradt). |

C. testudineus resembles in the pattern of the elytra C. 14-pustulatus, C. ocellatus, and

several other species; but I cannot identify it with either of these, the antenne being

very long and extending quite to the apex of the elytra. The head is entirely fulvous,

and the space between the eyes on the vertex is somewhat rugosely punctured ; the

antenne are black, with the basal four joints fulvous. ‘The thorax is entirely impunctate,

strongly convex, and proportionately long; fulvous in colour, with the margins and the

usual two basal spots very obscurely flavous. The elytra have each eight large flavous

spots in the same position as the allied species (3.2.2.1), these spots, however, being

divided by the rows of closely placed dark brown punctures into short longitudinal

stripes; the eighth row is interrupted before the middle by two short transverse rows

of punctures which enclose between them a raised and smooth space, a character

common to many species of this genus; the interstices are also longitudinally raised ;

and, moreover, there is a rather distinct transverse depression before the middle. The

underside and legs are entirely flavous or fulvous. The four male specimens received

do not vary from each other in any marked degree. The transversely raised smooth

space at the sides of the elytra would place C. testudineus near C. patheticus and other

species of Suffrian’s eleventh group, from all of which it differs in the long antenne

and in the deep punctuation and interrupted flavous spots of the elytra. The brown

colour of the elytral bands is much more intense in the specimen from Mexico.

In this species the dark elytral bands are apt to join each other, or, on the contrary,

to become obsolete; it is the two outer ones which generally unite. The thorax is

entirely impunctate, and the outer rows of punctures on the elytra are more or less

distinctly interrupted before and below the middle.

20(a). Cryptocephalus forreri. (Tab. XXXVIL. fig. 15.)

Broad and robust, fulvous; head finely, the thorax more strongly and closely, punctured; elytra flavous,

strongly subgeminate-punctate, the fifth row deeply indented in two places, each elytron with about five

brown spots placed between the strie.

Length 8 lines. . .

2. Head finely rugosely punctured at the vertex, the parts of the mouth piceous; antenne entirely fulvous,

extending to the middle of the body; thorax twice as broad as long, strongly narrowed anteriorly, the

sides nearly straight, the posterior angles strongly produced, the posterior margin finely serrate, and, like

the lateral margins, narrowly black, the surface closely and somewhat rugosely punctured, fulvous, with

a small almost obsolete piceous spot at the sides, the disc with an indistinct oblique depression on each

side near the base; scutellum flavous, margined with piceous; elytra broad, scarcely narrowed behind,

flavous, strongly punctured, the scutellar row consisting of five widely placed punctures, the other rows

arranged in pairs, the first and second confluent below the middle, the third and fourth near the apex, the

four following rows interrupted below the shoulder (the seventh and eighth united) and bounded lower

down by a transverse row of punctures connecting the fifth with the eighth row (the fifth row curved

abruptly inwards in two places and joining the eighth near the apex), the markings arranged thus—at the

junction of the first and second rows a brown spot is placed, and similar spots occupy the middle of the

following two rows, the junction of the fifth and sixth strie, the humeral callus, and the ends of the two

middle pairs of punctures, another spot is also visible below the first curve of the fifth row, and the

punctures themselves are also dark brown; pygidium rugosely punctured, fulvous, like the rest of the

finely pubescent underside and legs.

CRYPTOCEPHALUS. 107

The single female specimen received differs too much from any of its allies of Suffrian’s

eleventh group, with angulate fifth row of punctures, to identify it with either of these.

C. forreri is a large and robust species, which may be known by the finely and rugosely

punctured thorax and the other details mentioned above. When viewed without a lens,

the elytra seem to have about eight small brown spots, caused by the deeper coloured

interior of the punctures, the latter uniting here and there.

Cryptocephalus insolidus (p. 48).

To the locality given, add :—GuateMaLa, Calderas (Champion).

No specimen from Mexico has come under my observation; the one obtained by

Mr. Champion in Guatemala agrees sufficiently well with Suffrian’s description of

C. insolidus to be identified with it.

Cryptocephalus maculipennis (p. 48).

To the Mexican localities given, add:—Durango city, Iguala and Amula in Guerrero,

Tupataro in Guanajuato, Yautepec in Morelos (Hoge).

As already remarked when speaking of C. abruptus (Suppl., p. 99), there seems but

little to distinguish C. maculipennis from that species. The elytra in the present

insect are also punctured in pairs (not mentioned by Suffrian); and, instead of the

three black bands, have three rows of short brown longitudinal spots placed between

the punctures, if counted longitudinally or transversely.

23 (a). Cryptocephalus subcurvatus, (Tab. XX XVII. fig. 16.)

Fulvous ; thorax impunctate, the margins and two spots near the base obscure flavous ; elytra strongly

punctate-striate, the eighth row joined to the sixth anteriorly, flavous, a spot at the shoulders, another at

the apex, a semilunate band at the base, and a transverse band below the middle, black.

Length 2-23 lines.

Head punctured on the vertex, the latter of a darker brown tint than the lower portion of the face; labrum

piceous ; antenn black, the three or four basal joints fulvous ; thorax subcylindrical, narrowed in front,

entirely impunctate, with an obsolete oblique depression on each side, fulvous, the margins (the anterior

one narrowly) and two oblique spots near the base flavous ; scutellum black; elytra rather regularly and

deeply punctate-striate, the sixth row abbreviated before the middle and joined by a transverse row of

punctures to the eighth, the seventh and eighth rows also only visible just below the shoulder, the third

and fourth and the fifth and eighth rows united at the apex, the surface flavous with the following black

markings—a semilunate band at the base, the ends of which extend to the fourth row of punctures and

upwards to the basal margin, a slightly oblique band below the middle, dentate in the centre and a little

widened at the suture, and a small spot on the shoulder and a larger one at the junction of the united

strice at the apex ; the underside and legs dark fulvous.

Hab. Mexico, Ventanas in Durango (Hége).

The curved elytral band surrounding the scutellum principally separates C. subcurvatus

fromiits allies. The interrupted strie form in some specimens a smooth transverse

108 PHYTOPHAGA.—SUPPLEMENT.

space which in others is almost entirely absent, thus proving that reliance cannot

_ always be placed on the sculpture of the elytra as a specific character; there is some-

times a black streak placed along the suture near the apex. C. subcurvatus is somewhat

closely allied to C. atrofasciatus, Jac.

Cryptocephalus irroratus (p. 49).

To the localities given, add :—Mzexico, Villa Lerdo in Durango, Colima city, Cuerna-

vaca, Acapulco in Guerrero, Jalapa (Hége), Teapa (H. H. Smith), Temax in North

Yucatan (Gaumer); Panama, San Miguel in the Pearl Islands (Champion).

C. irroratus is a comparatively short and robust species, strongly narrowed posteriorly,

with a greatly developed and somewhat gibbous thorax. The coloration seems to be

subject to great variation. Suffrian describes the elytra as brown, with three sinuate,

obscure, transverse, flavous bands (this does not altogether answer to the insects referred

by me to C. irroratus), a definition I would rather give as yellow, with three more or

less distinct brown transverse bands; these bands are frequently broken up into spots,

but where they are more connected they separate well the yellow colour, which does

not at all appear obsolete (as Suffrian states in his diagnosis) ; ‘the punctuation is very

deep, widely placed, and partly irregular in both sexes, the punctures being frequently

connected by transverse wrinkles, and there is no trace of any arrangement in pairs ;

and frequently the first brown band is only indicated by a sutural spot. C. trroratus

may principally be known by the very coarse and distant punctures of the elytra; the

specimen from Panistlahuaca mentioned on p. 49 represents, I think, a closely allied

but distinct species.

Cryptocephalus trizonatus (p. 49).

To the localities given, add :—Acapulco, Las Vigas, Tapachula in Chiapas (Haye),

Atoyac in Vera Cruz (H. H. Smith), Temax in North Yucatan (Gauwmer); Brrvisu

Honpuras, Belize (Blancaneaux) ; GuaTeMaa, El Reposo, San Gerénimo, San Joaquin

(Champion); Costa Rica (Van Patten), Cache, Ivazu (Rogers); Panama, Volcan de

Chiriqui, Caldera, David, Petia Blanca, Taboga I. (Champion).

Nearly all the numerous specimens received from the State of Panama belong to a

pale variety in which the brown bands of the elytra are separated into spots or even

only indicated. C. trizonatus may be better described as having the elytra yellow, with

two transverse brown bands, and the thorax with a similar band at the middle; this

band on the thorax in some specimens is connected with the base by a narrow streak on

each side. ‘The punctuation of the elytra also varies, the punctures being placed more

closely in some examples than in others. C. trizonatus proves to be a widely distributed

and common insect in Central America.

CRYPTOCEPHALUS. 109

Cryptocephalus guatemalensis (p. 49).

To the localities given, add:—Mexico, Presidio, Ventanas (Forrer), Durango city,

Guadalajara in Jalisco (Hége); Guatemaua, Chimaltenango (Conradt).

Cryptocephalus xanthospilus (p. 50).

To the locality Mexico, add:—Colima city (Hége), Tepetlapa in Guerrero (Hi.

Smith), Panistlahuaca (Salé).

I give a renewed description of this species, that of Suffrian being no doubt based

upon insufficient material :—

Dark brown ; thorax finely rugose, the anterior margin narrowly and the lateral margins broadly, as well as

two narrow spots at the base, bright yellow ; elytra coarsely and closely punctate-striate, the basal margin, -

a narrow central transverse band, and the apex (two small brown spots excepted) yellow.

Length 24 lines.

Head punctured at the vertex, brown, a narrow transverse space between the eyes flavous; antenne more

than two-thirds the length of the body, the basal five joints fulvous, the others nearly black ; thorax

about one half broader than long, very strongly narrowed in front, the sides rounded, the surface finely

rugosely punctured throughout, dark brown, the anterior margin very narrowly, the lateral margins

broadly, yellow, the base with a short oblique yellow stripe on each side, the stripes not connected with

each other; scutellum brown ; elytra slightly narrowed posteriorly, the punctures very deep and closely

placed, but interrupted in the centre by the transverse flavous band (across which the fifth and seventh —

rows form short oblique rows of three punctures each) and again at the apex (so that only the remnants

of the fourth and fifth and sixth and tenth rows of punctures, joined posteriorly, are visible); the under-

side and legs dark brown, a spot at the side of the breast above the epipleurs and a narrow margin to

the ventral segments yellow.

Specimens from the above localities agree very closely with Suffrian’s description.

The elytral punctuation varies somewhat in our specimens, these having a short, strongly

oblique row of three or four punctures intersecting the central yellow band, a character

not mentioned by Suffrian. The elytra may be described as yellow, with two transverse

regular bands, one before, the other below the middle, and two small spots within the

apex of each, brown.

27 (a). Cryptocephalus complicatus. (Tab. XXXVII. fig. 17.)

Flavous, variegated with brown ; thowax dark brown, with eight large yellow spots placed transversely ; elytra

coarsely subgeminate-punctate-striate, flavous, this colour separated by longitudinal and transverse irre-

gular stripes ; femora brown, with a large yellow spot near the apex.

Length 2-24 lines.

Head flavous, a spot on the vertex, a short central line, and the base of the antenne brown; antenne two-

thirds the length of the body, the basal five joints fulvous, the others black ; thorax more than twice as

broad as long at the base, greatly narrowed in front, the posterior angles acutely produced, the surface

almost imperceptibly punctured, dark brown, with four flavous spots placed along the anterior and four

others along the posterior margin, the base with a short but distinct depression on each side near the

scutellum ; scutellum dark brown; elytra with the rows of punctures arranged in pairs, and placed in dark

brown strie below the middle, the fifth row connected at the apex with the eighth, but in front of this

making a wide turn inwards (so that it closely approaches the preceding rows and then turns back again

towards the shoulder), the broader space caused by this change of direction of the fifth row having some

110 PHYTOPHAGA.—SUPPLEMENT.

few brown punctures, the eighth row interrupted near the middle by a smooth raised yellow transverse

space, the complicated markings may be described thus—three transverse brown bands, one before and

one below the middle (both widened at the suture), and one near the apex, these bands separating the

yellow colour into differently-shaped spaces (five, more or less irregular, placed transversely across the

base, four at the middle, six, longitudinal in shape, below the middle, and one, in the shape of a trans-

verse spot, at the apex); pygidium yellow, with the margins and a central stripe brown; the under-

side entirely flavous, or with the sides of the breast and the ventral segments spotted with brown ; femora

flavous, marked with a piceous ring at the middle, their apices, as well as the tibiee and tarsi, brown.

Hab. Panama, Bugaba (Champion).

C. complicatus, of which male and female specimens were obtained by Mr. Champion,

seems to be closely allied to C. maculipennis and C. irroratus; but may be at once

known from either by the thorax having eight yellow spots—four placed along the

anterior margin and four along the posterior margin. The pattern of the elytra will

be best understood from our figure.

Cryptocephalus quatuordecimpustulatus (p. 51).

To the localities given, add:—Muxico, Acapulco, Tapachula in Chiapas (Hége) ;

British Honpuras, R. Sarstoon (Blancaneaux); GuateMaLA, Zapote, Calderas, San

Gerénimo, Purula, Chacoj, Sinanja, San Juan in Vera Paz (Champion) ; Costa Rica,

Cache (Rogers); Panama, Bugaba, Volcan de Chiriqui (Champion). |

Upon again comparing the specimens referred by me to C. 14-pustulatus with

Suffrian’s description, I find that they do not at all agree with it in the sculpture of the

elytra. Yet I cannot be mistaken as to the identity of the present species, it being

the only one from Mexico so marked which reaches the length of 24 lines. Specimens

contained in the collection of M. Sallé are labelled C. tesseratus (a synonym of C. 14-

pustulatus) ; and another in the same collection, from that of Sturm, which is quoted

by Suffrian, is labelled, in Sturm’s handwriting, C. 14-pustulatus.

In the thirty specimens before me the elytra are punctured as follows :—The first

subsutural row (not counting the short abbreviated sutural row) extends to below the

middle, where it ends, the second row is joined near the apex to the ninth, the third

and fourth and the fifth and eighth also being joined at the apex, the sixth and seventh

are only indicated anteriorly by a few punctures, the eighth is interrupted below the

shoulders and near the middle by a short row of transversely-placed punctures, which

between them leave a smooth slightly raised transverse space, and the third, fourth,

and fifth rows are closely approached at the middle, so that the other interstices appear

much wider; of all this Suffrian says nothing, this author merely stating that C. 14-

pustulatus may be separated from other allied species by the very finely punctured and

regular striz, and by the want of a smooth transverse space (‘‘ Querunzel ”) below the

shoulder. All the specimens from the State of Panama differ again from those from

Mexico in having regularly-punctured strie (that is, the strie are not interrupted by a

CRYPTOCEPHALUS. 111

transversely raised space) and a M-shaped thoracic mark; they agree in other respects,

but the elytra have frequently only seven instead of eight spots. It is quite possible

that these Panama examples represent a distinct species (perhaps another of Suffrian’s).

C. 14-pustulatus is placed by its author in a division in which the elytra have a deep

transverse depression below the shoulders: this depression is visible in most specimens,

though not to a very marked degree; the punctuation, however, in these examples,

does not accord with Suffrian’s description. C. guttulatus, Oliv., is a closely allied

North-American species; but Suffrian’s description of this insect does not agree so well

with the specimens from our region. C. guttulatus is, moreover, distinguished from

C. 14-pustulatus by the prosternum being anteriorly produced, a character not shared

by the Mexican insects.

This species is figured on Tab. III. fig. 7 under the name of C. tesseratus.

Cryptocephalus ocellatus (p. 51).

To the localities given, add :—Mexico, Oaxaca, Cerro de Plumas (Hége), Teapa

(Hl. H. Smith).

In most of the specimens which have come under my observation, notably in those

from Teapa, there are not more than five or six spots visible on each elytron, that is to

say, that five or six broad spaces are separated by narrow brown lines in the same

manner as in C. 14-pustulatus. Suffrian gives the number of these spots as eight; but

specimens so marked are probably rare. C. ocellatus is distinguished amongst its allies

by the deep and regular punctuation and the raised interstices of the elytra ; the speci-

mens from Teapa are of a very pale flavous colour.

Cryptocephalus rhombeus (p. 52).

_ The Guatemalan localities quoted, and my remarks on the Guatemalan specimens and

on the one from Zapote figured, refer to C. patheticus. C.rhombeus must be considered

as a very doubtful species, it having been described from a single female example.

C. patheticus, on the receipt of a large amount of additional material, proves, like many

of its allies, to be a very variable insect.

32 (a). Cryptocephalus decemplagiatus. (Tab. XXXVII. fig. 18.)

Dark brown, the head, the anterior and lateral margins of the thorax, and two spots at the base of the latter,

flavous; elytra finely punctate-striate, the punctures interrupted at the sides, brown, a spot near the

scutellum, three others placed triangularly at the apex, and a large oblique spot at the sides, yellow.

Length 1-13 line. . |

Head scarcely visibly punctured, flavous, the vertex dark, the lower part of the face paler brown; antenne

two-thirds the length of the body, dark fulvous, the apical joints darker; thorax subcylindrical, entirely

impunctate, dark brown, the anterior margin at the middle, the lateral margins broadly, and two roundish

spots at the base, flavous ; -scutellum dark brown, with a fovea at the base; elytra nearly cylindrical,

finely punctate-striate, the scutellar row only indicated by a few punctures below the yellow spot, the

112 PHYTOPHAGA.—SUPPLEMENT.

first and second rows united below the middle, the third and fourth and the fifth and eighth rows joined

at the apex, but interrupted before the middle, the other rows only distinct at the base, the five yellow

spots placed thus—one near the scutellum, one, large and somewhat pear-shaped, occupying the middle of

the lateral margin (commencing at the shoulder, surrounding the humeral callus, and extending down-

wards to below the middle), a smaller one beyond this at the sides and another at the apical angle, and

one near the suture before the apex; underside brown, the pro- and mesosternum, and the first ventral

segment and the apex of the last, yellow; the pygidium yellow with a brown central line and margin, or

brown with two yellow, spots.

Hab. Panama, Boquete in Chiriqui 3000 feet (Champion).

C. decemplagiatus may be compared in coloration to certain varieties of C. rhombeus,

Suffr.; but is perfectly distinct from that species. It may be known from it by the

distinct yellow markings of the thorax and the fine punctuation of the elytra, and also

by the large yellow lateral spot of the elytra only showing a few punctures at its lower

end; the antenne are also much longer than in C. rhombeus. The dozen specimens

obtained show scarcely any variation except in size.

Cryptocephalus militaris (p. 53).

To the localities given, add :—Mzxioo, Tonila in Colima, Chilpancingo, Iguala, and

Acapulco in Guerrero, Matamoros Izucar in Puebla, Tacambaro and Huetamo in

Michoacan, Cuernavaca (Hége), Ringon, Acaguizotla, and Amula in Guerrero (H. H.

Smith); Honpuras (Sallé).

In some of the additional specimens now before me the elytra want the red apical

spot, and also differ considerably in sculpture from the typical form ; in the latter they

are impressed with very deep subfoveolate and not closely arranged punctures, the

interspaces of which form strongly raised transverse rugosities, while in the variety

without the apical spot they are much more regularly and more closely punctate-striate,

the punctures being shallower and the interstices longitudinally costate at the sides and

at the apex. Both forms (¢, 2) were, however, obtained in various localities. In

another variety, specimens of which were obtained at Cuernavaca, Amula, and Chilpan-

cingo, the punctuation of the elytra is closer, shallower, and regularly placed, the inter-

spaces being scarcely, if at all, transversely raised, and the basal spot is interrupted at

the suture.

Cryptocephalus basalis (p. 53). (Tab. IV. fig. 6, var.)

To the localities given, add:—Mexico, Ciudad and Milpas in Durango (forrer),

Ventanas and Refugio in Durango, Huetamo in Michoacan, Acapulco and Chilpancingo

in Guerrero (Hége), Omilteme in Guerrero 8000 feet (H. H. Smith).

I have already remarked that in my opinion C. cruentatus is only a colour-variety of

C. basalis; this opinion is further strengthened by a male specimen of C. dasalis now

before me, which has all the structural] peculiarities (raised prosternum and dilated and

CRYPTOCEPHALUS. 113

curved posterior tibiee) pointed out by Suffrian as distinguishing the male of C. eruen-

taius. Both forms vary much in size and very greatly in colour; the pubescent upper

surface will, however, help in the recognition of C. dasalis.

The reference to the insect figured on Tab. IV. fig. 6 was omitted on p.53; it repre-

sents the variety cruentatus, Suffr.*

36 (4). Cryptocephalus smithi.

Black ; head pubescent ; thorax finely wrinkled, the margins and two spots at the base reddish-fulvous ; elytra

deeply and closely punctate-striate, fulvous, a quadrate sutural spot at the base, a transverse band below

the middle, and a spot near the apex, black.

Var. Thorax fulvous, with three black spots; elytra with the markings less distinct ; legs fulvous,

Length 2-22 lines,

Head closely punctured, sparingly clothed with whitish pubescence ; antenne nearly as long as the body in the

male, black, the lower four joints fulvous; thorax twice as broad as long, the sides moderately rounded,

narrowed towards the front, the surface finely wrinkled and punctured, black, the anterior and posterior

angles rather broadly, the anterior margin narrowly, and two rather obscure spots at the base, fulvous ;

scutellum black, raised, subquadrate; elytra cylindrical, closely and deeply impressed with somewhat

transversely-shaped punctures, the interstices transversely wrinkled at the sides, the first and second, the

third and fourth, and the eighth and ninth rows joined at the apex, the surface reddish-fulvous, with a

quadrate sutural spot at the base, a narrow transverse band below the middle, not extending to the sides,

and a small spot placed at the end of the rows of punctures, black; underside and legs black, finely

pubescent.

Hab. Mexico, Omilteme and Chilpancingo in Guerrero (H. H. Smith).

Allied to C. sordidus, but differing in the black thorax and legs, and the strongly

marked black pattern of the elytra; the female is more robust. In the variety the

fulvous colour predominates, and the elytra have only some small black spots in the.

same position as the bands in the type.

C. dolorosus is more finely punctured, and differs in the design of the elytra.

Cryptocephalus levipennis (p. 55).

To the localities given, add :—-GuatemaLa, Duefias (mus. Stuttgart).

An extremely variable species in regard to colour, scarcely two specimens being alike ;

the elytra are sometimes almost entirely black, with two yellow spots only at the apex,

and the thorax is equally variable in this respect.

Cryptocephalus inconspicuus (p. 56).

To the localities given, add :—Mzexico, Atoyac in Vera Cruz (H. H. Smith), Cerro de

Plumas (Hége).

Several examples of this comparatively large species have also been recently obtained

by Herr Conradt at Panzos, and another is contained in the Stuttgart Museum. None

of the specimens vary to any perceptible degree ; the regularity of the elytral strie,

with only an indication of the seventh row at the shoulder, the raised interstices, and

ihe absence of any markings (a small brown spot at the shoulder excepted), as well as

the uniformly flavous or pale fulvous colour, will help to distinguish C. inconspicuus.

Cryptocephalus zapotensis (p. 56).

To the localities given, add:—Mexico, Tapachula in Chiapas (Hoge); GUATEMALA,

San Isidro, Chacoj (Champion).

Cryptocephalus auratus (p. 57).

To the localities given, add:—Mexico, Saltillo in Coahuila (Dr. Palmer), Xucuma-

natlan and Chilpancingo in Guerrero (H. H. Smith), Orizaba (Sallé); Panama, Volcan

de Chiriqui, Pefia Blanca (Champion).

42 (a). Cryptocephalus amulensis.

Black, above dark metallic blue, the basal joints of the antenne and the tibiee and tarsi obscure fulvous ; thorax

impunctate ; elytra finely punctate-striate, with two tubercles below the shoulders, the interstices convex

at the sides.

Length 1 line.

Head with its lower portion rather deflexed, obscure piceous, the space near the eyes marked with flavous, the

intraocular space impressed with a distinct longitudinal groove; antenns with the three or four basal

joints flavous beneath, piceous above (the last five joints wanting); thorax twice as broad as long, convex,

the sides rounded, the surface entirely impunctate ; scutellum slightly longer than broad, without basal

fovea ; elytra cylindrical, of a lighter blue tint than the thorax, finely and regularly punctate-striate on

the disc, the rows of punctures interrupted below the shoulders by a short transverse tubercle, the latter

followed by a short, oblong, strongly raised ridge, the outer interstices also longitudinally costate ;

prosternum longer than broad, its posterior margin produced at each angle into a point.

Hab. Mexico, Amula in Guerrero (H. H. Smith).

Although only a single female specimen of this insect was obtained, the curious and

almost unique sculpture of the elytra will readily distinguish C. amulensis; the punc-

tures are plainly visible on the middle of the disc, but very obscure at the sides, and

the short and more elongate tubercles are isolated and strongly marked.

45. Cryptocephalus ccelestinus.

Below black, above metallic blue, the base of the antennz, the anterior tibia, and the base of the femora

flavous; thorax extremely finely punctured; elytra finely punctate-striate, the sixth and seventh strie

obsolete.

Length 2 line.

Head depressed between the eyes, dark blue, the labrum fulvous, the clypeus much broader than long ; antenne

scarcely half the length of the body, the lower five joints fulvous, the others black, the terminal joints

distinctly widened ; thorax twice as broad as long, the sides nearly straight, narrowed in front, the poste-

rior angles acutely produced, the surface extremely minutely punctured (the punctures only visible under

a strong lens) and with a narrow and obsolete transverse groove in front of the basal lobe; scutellum

not raised, as broad as long, dark blue; elytra finely and rather regularly punctured, the sixth and

seventh rows only indicated by a few punctures, the interstices between the eighth and following rows

convex; underside black; the anterior legs, the base of the posterior femora, and the tibie and tarsi, flavous.

Hab. Panama, Volcan de Chiriqui (Champion).

The bright metallic blue colour, the finely punctured thorax, and the colour of the

legs distinguish C. celestinus from several small metallic species inhabiting South

America.

46. Oryptocephalus sculptilis.

Flavous; thorax closely punctured, the disc obscure piceous; elytra very closely and deeply punctured, the

interstices convex, the space between the fifth and eighth rows also deeply and irregularly punctured, all

the punctures piceous.

Length 2} lines.

Head closely and strongly punctured, with a central darker mark; antenna two-thirds the length of the body,

entirely fulvous; thorax at the base twice as broad as long, of half the width anteriorly, the posterior

margin finely serrate and very narrowly black on the extreme edge, the surface closely and finely, but

somewhat irregularly, punctured, piceous, the margins flavous; scutellum flavous, margined with black ;

elytra flavous, the punctures very deep and closely placed, piceous, the first row joined to the second

below the middle, the third and fourth rows united at the apex, the fifth row curved outwards near the

apex and there joined to the eighth, the intervening space impressed with transversely placed and other

deep punctures and above the middle by another transverse row of punctures which interrupts the short

sixth row below the shoulder, the seventh row entirely absent, the interstices longitudinally costate ;

underside finely pubescent, flavous, the breast darker; the legs fulvous, the femora with a flavous spot at

the apex.

Hab. Mexico, Ventanas in Durango (Hége). A single specimen.

From the large-sized pallid unicolorous species inhabiting our region C. sculptilis

differs in the sculpture of the elytra, the punctures being deep, closely placed, and of

rather transverse shape, and the interstices longitudinally convex; the space between

the fifth and eighth striz is also closely punctate.

In the last-mentioned character C. sculptilis differs from all other species of the

genus known to me.

47. Cryptocephalus graphipterus.

Piceous; thorax fulvous, the margins and two spots at the base pale yellow; elytra flavous, strongly punctate-

striate, a sutural stripe, narrowed posteriorly, piceous,

Var. Elytral stripe dark metallic green.

Length # line.

Head flavous, a central stripe between the eyes and the parts of the mouth brown; antenney black, the basal

four joints flavous, the terminal joints slightly thickened ; thorax twice as broad as long, the surface finely

punctured, fulvous, the margins narrowly and two small oblique spots at the base flavous; scutellum

elongate, raised ; elytra with uninterrupted and strong rows of punctures, the sixth row consisting of a

few punctures only ; the seventh row entirely absent, the interstices at the sides convex, the surface

flavous, a small spot at the shoulders, a stripe along the suture (pointed at the apex) and the lateral

margins, piceous ; underside fulvous, i one example stained with piceous ; legs fulvous.

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

This small species is of cylindrical shape, and may be known from its allies by the

piceows or greenish sutural stripe, which in one specimen, however, is very obscure.

Only two examples were obtained. |

Length 2 lines.

Head fulvous, impressed with a few fine punctures and a short central groove, the clypeus rather deflexed and

darker; labrum flavous, raised ; eyes widely separated ; antenne with the basal four joints fulvous (the

other joints broken off); thorax at the base nearly two and a half times broader than long, convex and

widened at the middle, the sides slightly rounded, the surface extremely minutely granulate and punc-

tured (or finely wrinkled, when seen under a strong lens), black, the middle portion of the anterior

margin, the sides, and two spots at the base, pale fulvous (or pale fulvous, the disc occupied by a large

N-shaped black mark from each side of which a branch extends upwards to the anterior margin); scutellum

scarcely longer than broad, black, stained with fulvous in the middle, and with the usual groove at the

base ; elytra broad, not very convex, slightly narrowed posteriorly, the punctuation fine, the punctures

(as well as the rows themselves) widely separated, but becoming much closer near the apex, the eighth row

interrupted for a long distance near the middle (the impunctate space, however, not raised nor bounded

by transversely placed punctures), the black portion interrupted by a broad transverse flavous band at

the middle (not quite extending to the suture and constricted in the centre by a protruding point of the

black band separating it from the apical spot), and the apex occupied by a large round flavous spot

(surrounded by the narrow black apical margin); underside and legs fulvous; the prosternum flavous,

produced anteriorly in the middle and very strongly so at the posterior angles into an acute point.

Hab. Mexico, Juquila (Hoge). A single specimen.

49, Cryptocephalus septempunctatus. (Tab. XX XVIII. fig. 2.) .

Pale fulvous, the antenne (the basal joints excepted), the apices of the femora, and the tibie and tarsi black ;

thorax closely punctured, with a central black spot; elytra finely punctate-striate, fulvous or flavous, each

with two spots at the base and one below the middle, black, the striz interrupted below the shoulder.

Length 14 line.

Head impunctate, pale fulvous, the eyes closely approached, the clypeus wedge-shaped, the mandibles black ;

antenne slender, two-thirds the length of the body, the basal four joints obscure fulvous; thorax scarcely

twice as broad as long, the anterior portion scarcely, the sides but moderately, deflexed, the latter straight

at the base, but little rounded, and narrowed in front, the surface with a rather deep transverse groove in

front of the anterior margin, rather strongly and closely punctured, and with a central rounded black spot ;

scutellum not longer than broad, without a basal fovea, fulvous, margined with black; elytra distinctly

punctate-striate, the first stria extending to beyond the middle, the sixth and seventh stria interrupted

below the shoulder by a transverse row of punctures and a little lower down by a similar row (including

a transverse, but not raised,’smooth space), all the striz more finely impressed below the middle, the

interstices also impressed with minute punctures, the black spots arranged thus—two at the basal margin,

placed transversely (one at the shoulder, the other near the scutellum), and a similar one immediately

below the middle (halfway between the lateral and sutural margin); pygidium and underside flayous or

pale fulvous; legs black, the femora fulvous at the base ; prosternum longer than broad.

Hab. Panama, Volcan de Chiriqui (Champion).

_ the dise obscure piceous ; elytra strongly punctured, the interstices and a spot on the shoulders more or

less piceous, the three outer interstices costate.

Length 1 line.

Head not visibly punctured, slightly depressed between the eyes, obscure fulvous; antenns extending to about

half the length of the elytra, fulvous, the five apical joints more or less fuscous; thorax twice as broad as

long, not very convex, the sides narrowed in front, the posterior angles acutely produced, the surface

impunctate (extremely minutely granulate when seen under a strong lens) and only slightly shining ;

scutellum not longer than broad, nearly black ; elytra rather regularly and strongly punctate-striate, the

second and third and the fifth and eighth striw joined at the apex, the sixth and seventh indistinct and

interrupted near the middle by a short raised smooth space, the remainder of the sixth and the two outer

interstices strongly costate ; the breast more or less piceous, the rest of the underside and the legs fulvous ;

prosternum subquadrangular, its posterior margin slightly concave.

Hab. Panama, Volcan de Chiriqui (Champion).

C. tricostatus varies in colour, some examples being nearly unicolorous testaceous and

others spotted with black at the shoulders and between the punctures (assuming the

shape of an obscure longitudinal band near the suture). ‘The principal characters by

which the species may be recognized are the entirely impunctate and minutely granulate

thorax and the costate lateral interstices of the elytra, the sixth interstice being inter-

rupted before the middle by the tubercular smooth raised short space which limits

the punctures below the shoulders; the extreme basal margin of the elytra is narrowly

black.

51. Cryptocephalus laterifasciatus.

Black, the head, the base of the antenne, and the thorax fulvous, the disc of the latter black and nearly

impunotate ; elytra greenish-black, deeply punctate-striate, the fifth and sixth interstices and the apex

flavous; legs fulvous.

Var. Thorax not marked with black on the disc.

Length -1 line.

Head with a longitudinal depression between the eyes, flavous, the eyes closely approached ; antenne half the

length of the body, the lower four joints flavous, the other joints black and distinctly thickened ; thorax

strongly narrowed in front, the sides rounded, the surface extremely finely punctured, fulvous, with a

plackish-green spot at the middle of the disc; scutellum strongly raised, scarcely longer than broad,

blackish-green ; elytra cylindrical, with distinct rows of punctures, the lateral interstices longitudinally

costate but interrupted below the shoulders by a short transverse smooth space which is bounded above

and below by a few deep punctures, the surface metallic greenish-black, the sides with a narrow flavous

longitudinal stripe which is connected by a very narrow streak with the flavous marking at the apex ;

pygidium black, with two obscure flavous spots at the sides; legs fulvous.

Hab. Guavemata, Pantaleon (Champion); Panama, Bugaba, Volcan de Chiriqui

(Champion).

In its peculiar coloration, this small species has no near ally amongst its many con-

geners from our region. Some specimens have the thorax fulvous, with the margins

paler; in others the disc is very obscurely marked with fuscous. In the male the sixth

elytral interstice is very distinctly interrupted below the shoulder ; in the female the cor-

responding transverse space is broader and less deeply bounded by punctures, but still very

plainly visible. The flavous stripe is confined at the base and near the apex to a single

118 PHYTOPHAGA.—-SUPPLEMENT.

interstice (extending to two interstices at the middle), and the flavous spot at the apex

is of transverse shape.

52. Cryptocephalus dolorosus. (Tab. XX XVII. fig. 19.)

Black, the basal joints of the antenne and the anterior and lateral margins of the thorax fulvous; thorax

finely rugose ; elytra deeply punctate, with anteriorly uninterrupted striz, fulvous, a spot at the shoulder

and a large subquadrate discoidal patch, black.

Length 23 lines.

Head closely and rather irregularly punctured, black; labrum fulvous; eyes not closely approached ; antenne

more than half the length of the body, black, the basal two or three joints sometimes fulvous ; thorax

more than twice as broad as long, but moderately narrowed in front, very closely punctured, the interspaces

slightly rugose, black, shining, the anterior margin narrowly (more widely.at the middle) and the lateral

margin reddish-fulvous, this colour widening at the anterior angles into a subquadrate spot; scutellum

short, black; elytra subcylindrical, scarcely narrowed posteriorly, the punctures deep and regular, the ten

rows present, the fifth and sixth abbreviated at some distance from the apex and, as well as the second

and third and the seventh and eighth rows, joined at their ends, the interstices slightly transversely

wrinkled, the surface of a bright reddish-fulvous colour, a small spot at the shoulder, and another (in one

specimen) near the apex, black, the middle of the disc occupied by a large common subquadrate anteriorly-

divided black patch which extends downwards to or beyond the middle, but does not quite reach the base ;

underside and legs black, finely pubescent, the tarsi obscure fulvous; prosternum not produced anteriorly,

much longer than broad, the posterior margin produced into a short and blunt tooth on each side.

Hab. Mexico, Las Vigas ({ége).

The very regularly punctured strie and the colour of the upper surface seem to place

C. dolorosus in Suffrian’s seventeenth group; the colour of the thorax and the marking

of the elytra will separate this species from any of its allies.

53. Cryptocephalus flavofasciatus. (Tab. XX XVII. figg. 20; 21, var.)

Metallic dark blue; thorax impunctate, the anterior and lateral margins yellow; elytra regularly and deeply

punctate-striate, metallic blue, a lateral longitudinal band, narrowed posteriorly, bright yellow.

Var. Entirely blue or with indications only of the lateral band.

Length 2-22 lines.

Head entirely blue, depressed between the eyes, closely and finely punctured ; antenne two-thirds the length

of the body, black, the basal joint more or less fulvous beneath ; thorax twice as broad as long, narrowed

in front, the posterior angles not much produced, the posterior margin only slightly concave at the sides,

the surface extremely finely punctured, with a slight oblique depression on each side at the base, the

anterior margin and the posterior half of the lateral margin very narrowly bright flavous, this colour

greatly extended at the anterior angles; elytra cylindrical, deeply and closely punctured, the third and

fourth and the seventh and eighth rows united at the apex, the yellow lateral stripe is formed thus—it

commences at the middle of the base and extends to the apex, but its posterior is only half the width

of its anterior portion, so that the lower half of the lateral margin and a small humeral spot remain

of the ground-colour; underside and legs metallic blue, the sides of the breast finely pubescent ; pro-

sternum longitudinally depressed, its posterior margin straight.

Hab. Mexico, Ciudad in Durango (f/ége, Forrer).

Of this handsome Cryptocephalus many specimens were obtained by Herr Hége, not

only of the type but of the variety also; in the latter there are generally more or less

distinct traces of the flavous colour at the sides of the thorax and of the elytra, but in

some examples the flavous colour is obliterated and the insect is entirely dark blue.

CRYPTOCEPHALUS. | 119

In the female the oblique impression on each side of the base of the thorax is much

more strongly marked than in the male.

54. Cryptocephalus flavomaculatus. (Tab. XXXVIIL. fig. 3.)

Black ; the head, the anterior and lateral margins of the thorax, and two spots at the base of the latter, yellow ;

elytra deeply punctate-striate, black, each with five yellow spots (1.2.1.1), the two apical ones transverse ;

femora yellow beneath,

Length 13 line. .

Head with a few punctures, the vertex black and impressed with a longitudinal groove, the rest of the surface

(except round the base of the antenne) yellow ; labrum piceous ; mandibles black; antenng black, the

lower four joints flavous ; thorax twice as broad as long, black, the anterior margins narrowly, the lateral

margins broadly (but interrupted at the middle by a short transverse black streak), flavous, the base

with two transversely-shaped yellow spots, the surface with a few scarcely visible punctures, the posterior

margin finely serrate ; scutellum rather short, its apex truncate; elytra with very deep and closely placed

punctures, the sixth and seventh rows interrupted below the shoulder by a smooth transverse space, the

lateral interstices strongly costate, the yellow markings arranged thus—a spot at the middle of the base,

two spots, more transversely-shaped, at the middle (the outer one extending upwards along the lateral

margin to the base), and a short band near and another at the apex, the latter surrounded by the narrow

black margin; pygidium yellow, with a black central band ; underside black, a spot above the anterior

coxe, another at the sides of the last ventral segment, and the prosternum flavous; legs black, the

entire under surface of the femora yellow.

Hab. Mexico, Ventanas in Durango (Hége). <A single specimen.

In this brightly-marked species the elytra have well-defined yellow spots, the posterior

spots being divided by the black punctures of the striae. These spots are placed as in

C. plagiatus and several other species, but are fewer in number ; the elytral punctuation

is much stronger and deeper than in the allied forms, it being well visible to the naked

eye.

55. Cryptocephalus multipunctatus. (Tab. XXXVII. fig. 22.)

Fulvous ; the head and thorax finely and closely rugose-punctate; elytra deeply, closely, and regularly

punctured, all the interstices strongly costate.

Length 2 lines.

Q. Head closely punctured at the vertex ; antennz entirely fulvous, the apical joints slightly darker ; thorax

quite twice as broad as long, fulvous, narrowly margined with piceous, the surface closely and finely

rugose, the interspaces finely punctured ; elytra each with ten closely-approached rows of deep punctures

divided only by narrow cost, the cost still more strongly raised at the apex, and here and there

connected by transverse wrinkles.

Hab. Mexico, La Parada (Sailé).

This Cryptocephalus is entirely falvous in colour and only represented by a single

female specimen. The sculpture of the elytra is, however, very different from that of

any other species of our region: all the punctures are extremely closely placed, the rows

divided by strongly raised coste, of which the sixth and seventh are joined at a little

distance from the apex, and connected behind by a short stem or branch with one

of the preceding and one of the following rows, which are also posteriorly united and

form a ridge parallel to the apical margin; the punctures and coste are nowhere inter-

rupted, although here and there running into each other, causing broader and irregular

smooth spaces. |

56. Cryptocephalus nigrofasciatus.

Black, the basal joints of the antenne and the legs fulvous; above flavous; thorax with a N-shaped black

mark ; elytra with a lateral transverse smooth space, strongly punctate, flavous, a broad irregular longi-

tudinal band on the disc, constricted at the middle, and a subapical spot, black.

Var. The elytral band almost obsolete. .

Length 14 line.

Head fulvous, sparingly punctured between the eyes, with a distinct central fovea; eyes but slightly sinuate,

widely separated ; clypeus triangular ; antennz about half the length of the body, the lower four or five

joints fulvous, the other joints black; thorax rather more than twice as broad as long, scarcely visibly

punctured, flavous, with a large M\-shaped black mark, or black with the lateral and anterior margins and

two spots at the base yellow; scutellum black; elytra rather strongly and regularly punctate-striate, the

first (subsutural) row of punctures abbreviated below the middle and closely approaching the second row,

this latter apparently joined at the apex to the two following rows, the fifth row turned outwards below

the middle, limiting a smooth transverse space, and beyond this parallel and eventually joining the eighth,

the sixth and seventh rows interrupted below the shoulder, the colour very variable—in well-marked

specimens the dise almost entirely occupied by a broad black band which is strongly constricted at and

abbreviated below the middle, this band being followed by a spot of variable size (placed at the junction

of the striw), the lateral margin also narrowly black; underside black, with the sides of the ventral

segments more or less testaceous ; legs entirely fulvous ; prosternum flavous, the posterior angles thickened

and of blunt triangular shape.

Hab. GuateMata, Quiche Mountains 8000 feet, Totonicapam 10,500 feet (Champion).

The elytral pattern of this species is only well defined in one or two specimens: it is,

no doubt, subject to great variation, as in the variety the black bands are indistinct.

The North-American C. incertus, Oliv., seems to be somewhat closely allied, but differs

in the coarsely punctured thorax and in having three bands on the elytra.

57. Cryptocephalus undecimplagiatus. (Tab. XXXVII. fig. 23.)

Black, the head, antenne, and legs fulvous; thorax impunctate, black, the anterior and lateral margins in

part and two large spots at the base obscure fulvous; elytra scarcely visibly punctate, each with two spots

at the middle, and one at the apex, pale fulvous.

Length 13-13 line.

Head impunetate, obscure fulvous ; mandibles black ; antenne two-thirds the length of the body, entirely

fulvous ; thorax subconical, twice as broad as long, the sides strongly narrowed in front, greatly deflexed,

and obliquely and very rapidly converging from the base, the posterior margin finely serrate, the surface

quite smooth, fulvous, with a black M\-shaped mark (or, if the black is taken for the ground-colour, with

five large fulvous spots—these consisting of a broad patch on the anterior margin and thestill broader one

along the lateral margins and two large oblique spots at the base); scutellum longer than broad, with a fovea

at the base; elytra scarcely twice as long as the thorax, broad, the punctures very minute (only visible

under astrong lens) and placed widely apart, the sutural stria, and the ninth also, more deeply punctured,

the surface black, with two large spots placed transversely across the middle of the disc (one lateral and

one near the suture), and a round spot at the apex, obscure fulvous; legs, prosternum, and last ventral

segment obscure fulvous, the rest of the underside black. _

Hab. Guatemata, San Juan in Vera Paz (Champion).

C. undecimplagiatus is well distinguished from its allies by the elytra being very

faintly punctured and with the spots of a dull flavous or fulvous colour.

CRY PTOCEPHALUS. 121

58. Cryptocephalus problematicus. (Tab. XX XVII. fig. 24.)

Reddish-fulvous, the sides of the breast, the apex of the femora, and the tibia piceous ; thorax impunctate ; elytra

strongly punctured, each with two spots at the base and another at the apex, and a short transverse band

below the middle, black.

Length 14-2 lines.

Head fulvous, with a deep longitudinal depression on the vertex, the lower portion with a few punctures, the

space between the points of insertion of the antenne with a deep transverse groove, the eyes rather closely

approached ; antenne black, the basal four joints fulvous; thorax nearly three times wider than long,

the sides finely marginate and rather distinctly rounded, the surface entirely impunctate, fulvous ; scutellum

scarcely longer than broad, foveolate at the base, fulvous, margined with piceous ; elytra broad, not very

convex, slightly narrowed posteriorly, the punctured stria deep and regular and rather wide apart, the

third, fourth, and fifth a little closer together than the others, the sixth and seventh only indicated

by a few separate punctures, the lateral lobe feeble, each elytron with four black spots—one at the

shoulder, a more transversely-shaped one near the scutellum, a smaller one at the junction of the fifth

and eighth strie, and a short transverse band, not extending to either margin, below the middle; the

knees, tibiz, and tarsi black, the breast more or less piceous and strongly punctured ; prosternum strongly

produced anteriorly into a cup-shaped protuberance.

Hab. Muxico, Cerro de Plumas (Hége).

Somewhat allied to C. quaternarius, Suffr., but differing from that species in its reddish

colour and in the number and position of the elytral spots.

59. Cryptocephalus admirabilis. (Tab. XX XVII. fig. 25.)

Fulvous, the apical joints of the antennae, the apex of the tibia, and the tarsi, black; above dark brown;

thorax extremely finely longitudinally strigose ; elytra with all the interspaces between the rows of coarse

punctures very strongly longitudinally costate.

Length 17 line.

Head fulvous, not visibly punctured; the eyes contiguous at the vertex, the space between the points of inser-

tion of the antennz with a depression ; mandibles black; antennz slender, extending to the end of the

elytra *, black, the lower four joints fulvous, the third and following joints very elongate ; thorax more

than twice as broad as long, the sides rounded, very distinctly margined, and with a fovea placed at some

distance within the margin at about the middle, the base with a deep oblique depression on each side near —

the scutellum, the disc (when viewed under a strong lens) extremely closely and finely longitudinally

strigose (giving the surface a silky gloss with whitish reflections) ; scutellum very narrowly elongate ;

elytra narrowed posteriorly, castaneous, the interspaces between the rows of coarse punctures occupied by

strongly raised longitudinal coste which are interrupted for a little distance below the shoulder, the

punctures often connected by transversely raised spaces.

Hab. Panama, Bugaba (Champion).

Of this most interesting species only a single specimen was obtained by Mr. Cham-

pion. It belongs, without doubt, to Suffrian’s seventeenth group, being evidently allied

to the Brazilian C. dar, Fabr., and C. carneolus, Perty; it differs, however, from both

these in having the thorax extremely finely strigose (instead of punctured) and ofa

somewhat purplish-brown colour with light reflections. The elytral cost are here and

there interrupted, but are for the most part joined near the apex: our figure will give

a better idea of their shape.

60. Cryptocephalus constricticollis.

Entirely pale fulvous or flavous; thorax impunctate, deeply obliquely grooved at the sides; elytra strongly

punctate anteriorly, the interstices at the sides and the one within the shoulders strongly costate.

Length 1-12 line.

Head impunctate, flat, pale flavous, the eyes closely approached, the labrum brownish; antenne flavous, two-

thirds the length of the body in the male, the basal two joints strongly swollen, the following four joints

slender and elongate, the terminal ones slightly widened ; thorax twice as broad as long, of nearly equal

width, the sides straight at the base, rounded in front, and strongly deflexed, the surface impunctate,

with a very deep oblique groove on each side near the base, the groove not reaching the lateral margin

but extending shallowly across the base; scutellum narrowly elongate, strongly pointed ; elytra slightly

wider at the base than the thorax, nearly parallel, transversely depressed below the base, deeply punctured »

anteriorly, more feebly so posteriorly, the fourth row of punctures divided into two branches below the

shoulder and followed by a short, oblique, strongly raised costa, the lateral interstices also strongly

costate ; underside and legs flavous; prosternum nearly quadrate, its posterior margin straight.

Hab. Panama, Bugaba, Volcan de Chiriqui, David (Champion).

This small Cryptocephalus is of peculiar shape, and in the form of the thorax it

resembles some species of the genus Scolochrus; it differs, however, from Scolochrus

and the allied genera in the form of the prosternum. C. constricticollis resembles

C. esuriens, Suffr., from Parad, in the uniform flavous colour; but it has the thorax

transversely subquadrate, with the lateral groove deeply impressed (more deeply so

than in any species of the genus known to me) and extending shallowly across the entire

base, giving the anterior portion a swollen appearance. The sculpture of the elytra is

again peculiar, there being a short oblique costa within the shoulder ; the seventh row of

punctures is entirely absent, and the interstices which follow are strongly costate; all

the rows of punctures are abbreviated at some distance from the apex, the latter in

consequence being entirely smooth and impunctate.

Many specimens.

STEGNOCEPHALA. (To precede the genus Scolochrus, p. 58.)

Stegnocephala, Baly, Trans. Ent. Soc. Lond. 1877, p. 32.

This genus is stated by its author to differ from M/onachus in the different structure

of the prosternum, large size, larger eyes, longer antenne, &c.; and from Crypto-

cephalus in its broader form, widely separated hind coxe, and more strongly produced

lateral lobe of the elytra. The species hitherto included in Stegnocephala are from

Tropical South America; one of these extends northwards to the State of Panama,

whence two additional species are now added.

1. Stegnocephala perplexa.

The differences, if any, between the Panama specimens and one from the Amazons

region contained in my collection are too trivial to be regarded as specific. In

S. perplexa the head, thorax, underside, and legs are flavous or fulvous, and the

elytra metallic blue or violaceous.

2. Stegnocephala costata. (Tab. XXXVIII. fig. 4.)

Broadly ovate, robust, fulvous, the apical joints of the antenne and the scutellum black; thorax scarcely

perceptibly punctured; elytra dark metallic blue, strongly punctured, the interstices strongly longitudi-

nally costate.

Length 14 line.

Head impunctate ; eyes closely approached ; antennez scarcely half the length of the body, black, the lower

four joints fulvous; thorax strongly deflexed at the sides, the latter much narrowed in front and rapidly

and obliquely converging from the base, the surface finely and very obsoletely punctured; scutellum

elongate, triangular, black, impunctate; elytra raised at the base, the shoulders very prominent and

tuberculate, the punctures deep and closely placed, the interstices strongly costate throughout ; epipleurse

black, produced at the base, and coarsely punctured.

. Hab. Panama, Bugaba (Champion).

S. costata, of which only a single specimen was obtained, differs from S. perplexa in

the strongly costate elytral interstices.

3. Stegnocephala longicornis. (Tab. XX XVIII. fig. 5.)

Subcylindrical, robust, black ; antenne long and filiform, the basal joints fulvous; thorax deeply depressed at

the base, finely punctured ; elytra reddish-fulvous, strongly punctate-striate, a sutural spot below the

middle black.

Length 14 line.

Head finely granulate ; the eyes very closely approached in the female, touching at the vertex in the male;

the epistoma bounded by a transversely raised ridge between the antenne; the anterior edge of the

labrum and the palpi fulvous ; antenne two-thirds the length of the body, filiform and slender, the lower

four joints fulvous, the others black; thorax more than twice as broad as long at the base, much

narrowed in front, the sides with a very narrow margin, the posterior margin strongly oblique, the surface

rather closely and finely punctured, with a deep transverse depression in front of the scutellum, the

depression rather strongly punctured; scutellam elongate, pointed, with a fovea at its base; elytra convex,

subcylindrical, scarcely narrowed posteriorly, the shoulders very prominent, the lateral lobe strongly

subangularly produced, the surface very deeply punctured, the punctures more finely impressed poste-

riorly, the interstices slightly convex and minutely punctured, the surface of a bright reddish-fulvous

colour, with a common black ovate spot placed across the suture below the middle and slightly prolonged

into a point upwards ; underside and legs piceous; prosternum much broader than long, rugosely punc-

tured, the posterior margin but slightly concave, the angles acute.

Hab. Panama, Bugaba, Volcan de Chiriqui, Caldera (Champion).

If the antenne and the prosternum of the present insect are examined, it will be

seen that S. /ongicornis cannot find its place in either Cryptocephalus or Monachus, and

that it agrees much better with Stegnocephala; but even from the last-named genus

the entirely filiform antenne seem to separate it. Suffrian has described several species

of Monachus which have a similarly depressed or posteriorly grooved thorax, and are

also somewhat allied in their system of coloration to the present insect ; S. longicornis

cannot, however, be possibly mistaken for any true species of Monachus.

124 PHYTOPHAGA.—SUPPLEMENT.

SCOLOCHRUS (p. 58).

If the diagnoses of the genera Scolochrus and Metallactus are compared it will be -

seen, as their author states, that no differences of importance exist, although they differ

slightly in the form of the prosternum &c. In my opinion it matters not whether the

two genera in question are maintained or united into one, as it will always be necessary

to compare Suffrian’s descriptions of the numerous species of either genus (and indeed

of Pachybrachys also) when the determination of any is in question: for the present I

have placed all those from our region in Scolochrus. The separation of these into species

is frequently very difficult and doubtful, owing to the great variability they are subject to;

I have, however, been enabled to compare them with many of Suffrian’s types contained

in the British Museum. |

We have now to add no Jess than eighteen additional species to our list, fifteen of

which are described as new, the majority of these latter being from the State of Panama.

Scolochrus purpurascens (p. 58).

To the localities given, add :—Mexico, Acapulco in Guerrero (Hége), Juquila (Sad/é) ;

Costa Rica, Cache (Rogers); Panama, Volcan de Chiriqui (Champion).

Var. a. Entirely dark purplish.

Var. b. Elytra flavous.

S. purpurascens apparently varies as much in colour and punctuation as S. albilabris,

and it is difficult to find two exactly similar specimens. The former is chiefly distin-

guished by the thorax being rather suddenly narrowed in front, and having a purplish

and very finely punctured surface. In the Mexican specimens the black transverse

band of the elytra extends upwards along the suture to a greater or less degree; in

those from Panama, however, the band is regular in shape and the suture remains of

the red ground-colour. The legs vary from red to black, and the punctuation of the

elytra is also very variable, so that almost every specimen might be treated as a distinct

species, if too much importance is attached to these variations. The sides of the thorax

are often reddish in colour and clothed with hairs; these latter are sometimes entirely

absent. Specimens also occur in which the red colour of the elytra is replaced by

violaceous or purplish (var. a), or even by yellow (var. 6). The varieties were all

obtained in Chiriqui in company with normally-coloured forms,

Scolochrus albilabris (p. 59).

To the localities given, add:—Mexico, Acapulco and Chilpancingo in Guerrero,

Tacambaro and Huetamo in Michoacan, Tupataro in Guanajuato (Hége), Rincon, Dos

Arroyos, and Amula in Guerrero (H. H. Smith); Nicaragua, Chontales (Belt).

The two specimens obtained by Herr Hége at Tupataro must, no doubt, be included

SCOLOCHRUS. 125

among the numerous varieties of 7. aibilabris. In one of these examples the thorax

is black, with the anterior and lateral margins, a narrow central longitudinal band

extending to the middle, and two spots at the base, flavous, and the tibie and the

greater part of the femora also flavous ; in the other the thorax has the disc black, the

central band only just indicated, and the basal spots absent. In these two specimens,

as well as in those obtained at Huetamo, the scutellum and the entire pygidium are

likewise flavous, thus answering partly to Suffrian’s description of S. suturalis.

Scolochrus zonatus (p. 59).

I think it very probable that S. zonatus is but another variety of S. albilabris; the

differences pointed out by Suffrian do not seem to be important enough to separate it

from S. albilabris, which is one of the most variable species of the genus.

4 (a.) Scolochrus pallipes. (Tab. XXXVIILI. figg. 6, 7, var. 3.)

Black, the scutellum, legs, pygidium, and sides of the abdomen pale yellow ; head, and the anterior margin of

the thorax, rufous ; elytra finely punctate-striate, rufous, a transverse band across the middle, and a

humeral spot, black.

Var. a. Thorax black, the sides and two spots at the base flavous; elytra black, with an oblique basal trans-

verse red band.

Var. 6. Thorax and elytra entirely black.

Length 24 lines.

. Head entirely rufous, with a few punctures at its lower portion ; eyes distant, very large and triangularly

notched ; labrum flavous ; mandibles black; antenne extending only to the base of the elytra, black, the

basal joint flavous, the following four joints marked with flavous at the base only, shining, the terminal

joints widened, the fourth twice as long as the preceding joint; thorax three times broader than long, the

sides strongly and rather suddenly narrowed in front, the disc with a few fine punctures, the sides a little

more strongly and closely punctured and with an oblique moderately deep depression, the surface black,

the anterior margin (more widely so at the middle), a spot in front of the scutellum, and the extreme

posterior angles fulvous ; scutellum yellowish-white, smooth ; elytra scarcely narrowed behind, the basal

margin strongly raised, the punctures fine and rather regular and distinct to the apex, bright red, with a spot

at the shoulders, the middle of the disc, and a transverse band (narrowed at the suture and not extending

to the sides, its anterior margin strongly convex, its posterior one concave between each alternate row of

punctures), black; underside black, the closely punctured prosternum, the sides of the last ventral segments,

the pygidium, and the legs, nearly white; the upper portion of the anterior femora and their tibie light

brown.

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

At first sight this species might easily be mistaken for one of the numerous varieties

of §. albilabris. It differs, however, from &. albilabris, not only in colour, but in the

shape of the thorax (which resembles that of S. purpurascens) and in the much finer

elytral punctuation. 8. pallipes seems to be subject to the same amount of variation

as S. albilabris, the five specimens received being all somewhat differently coloured.

In the var. a the thorax, instead of having the anterior margin fulvous, has the sides of

that colour, and the elytra marked as in some varieties of S. albilabris ; while in the

var. @ the thorax and elytra are entirely black. But in all these forms the sides of the

abdomen and the pygidium, as well as the legs, remain pale yellowish. We figure two

examples, one of the typical form and one of the var. 0.

Scolochrus suffriani (p. 60).

Var. 2. The anterior edge of the thorax narrowly flavous ; elytra black, with a quadrate whitish sutural spot

at the base.

Hab. Mexico, Iguala in Guerrero (Hége).

- J must refer a female example of a Scolochrus lately received to S. suffriani, with the

type of which, a male, it agrees in its principal characters, although differing from it in

colour. The eyes in this female specimen are, as usual, more widely separated than

those of the male, while the thorax is shorter and more transversely shaped ; the latter is

coloured exactly as in the type, with the exception of having the anterior edge narrowly

flavous; the elytra are more regularly punctured than in the male, and the black portion

predominates to such an extent as to leave only a whitish quadrate sutural patch at the

base ; and the pygidium and the abdominal segments are yellowish, as in the type. It

is probable that S. suffriani is as variable in colour as most of the species of Scolochrus.

In the allied S. cazicus the pygidium is black.

Scolochrus decoratus (p. 61).

To the localities given, add:—Mexico, Temax in North Yucatan (Gaumer) ;

GuatemaLa, Panzos (Conradt).

Another variety of this species has been received from Yucatan, this having the

elytra entirely black. Entirely fulvous specimens, as well as normally coloured or

spotted ones and the black variety, were received from Mr. Gaumer.

13 (a). Scolochrus panamensis. (Tab. XXXVIII. fig. 8.)

Black ; thorax finely punctured, the sides red and closely and more strongly punctate; elytra closely punctate-

striate, a quadrate spot at the shoulders, and the apex, red; abdomen, pygidium, and the underside of the

femora yellowish-white.

Length 2 lines.

Q. Head entirely black, very finely and rather closely punctured ; antenne slender, black, the terminal joints

not thickened ; thorax about two and a half times broader than long, narrowing from the middle to the

apex, the dise black and closely and finely punctured, the sides broadly red, strongly punctured, and with

a shallow oblique depression ; scutellum black, very finely punctured ; elytra slightly narrowed posteriorly,

the punctures strong and closely placed in rows, those near the suture irregularly arranged, black, a large

quadrate spot occupying the shoulders and the entire lateral lobe, and a round spot at the apex, red ;

underside finely pubescent, the entire abdomen and the pygidium almost white; legs black, with the

exception of the underside of the four posterior femora and the base of their tibie.

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

S. panamensis, of which two female specimens only were obtained, may be distinguished

from S. purpurascens by the thorax being glabrous at the sides and also differently

SCOLOCHRUS. , 127

coloured; from S. albilabris and its varieties by the close punctuation in connection

with the different colour ; and from 8. jfotens by the colour of the thorax and the

elytral pattern. It is, however, not improbable that S. panamensis is a variety of

S. feetens ; but, taking into consideration the great variability to which these insects

are subject, additional specimens are required to come to a more definite conclusion.

Scolochrus fotens (p. 63).

To the locality Panama, add :—Taboga I. (Champion).

A male of this species, which sex was unknown to Suffrian, was obtained by

Mr. Champion ; it agrees in most respects with the female, but the red colour is

replaced by yellowish-red, the eyes are contiguous, and the thorax is finely and rather

closely punctured.

Scolochrus sulcipennis (p. 63). (Tab. IV. fig. 4.)

To the locality Panama, add:—Volean de Chiriqui, David, Caldera, Taboga I.

(Champion).

Many specimens of this species were obtained by Mr. Champion in Chiriqui. It proves

to be more constant in coloration than is usually the case in this genus; amongst these

Chiriqui examples, however, are some in which the sutural portion of the elytra is more

or less yellowish-white. S. sulcipennis has the upper surface entirely opaque.

The reference to the Plate was accidentally omitted on p. 63.

16. Scolochrus maculicollis. (Tab. XX XVIII. fig. 9.)

Piceous, the head and a spot on the anterior part of the thorax black, the latter finely punctured ; elytra strongly

.subgeminate punctate-striate, the sutural and lateral margins, a narrow transverse band at the base and

another below the middle, black.

Var. The thoracic spot obsolete ; elytra fulvous, with the margins and a spot at the shoulders black.

Length 2 lines.

Head black, sparingly punctured ; the labrum and oral organs fulvous; eyes (9) not closely approached ;

antenne black, the lower joints stained with fulvous at their base; thorax narrowly transverse, strongly

narrowed from the middle to the apex, the surface very finely but not very closely punctured, the punctures

_ a little coarser at the sides, the latter with an obsolete transverse depression near the base, pale fulvous,

the disc with a smaller or larger black spot placed at the middle of the anterior margin and a short piceous

stripe in the centre; scutellum black ; elytra with distinct strie of punctures, the stria placed somewhat

in pairs, the interstices also impressed with scattered punctures (those near the suture very closely

approached in pairs), the surface fulvous, a narrow transverse band at the base and another below the

middle, widened at the sides and connected along the lateral and sutural margins with each other, black ;

the pygidium and the sides of the abdomen nearly white; legs fulvous, the femora more or less darkened

or stained with piceous, the posterior tibiew often paler.

Hab. Panama, Bugaba, David in Chiriqui (Champion).

S. maculicollis is very similar in coloration to S. fetens, Suffr.; but differs from it in

the punctuation of the elytra. In S. feetens the thorax is crowded with small punctures

128 PHYTOPHAGA.——-SUPPLEMENT.

and the elytra are almost equally closely punctured; while in the present insect the

strie of the elytra are subgeminate and the interstices broad and with only a few

punctures. The male of 8. maculicollis is unknown to me, but of 8. fatens we have

examples of both sexes. In the variety the anterior portion of the thorax is only

obscurely stained with piceous, and the elytra are without bands, the extreme apex of

the latter being whitish and the margins very narrowly black, a small black spot being

also placed on the shoulders. |

17. Scolochrus quinque-maculatus. (Tab. XXXVIII. fig. 10.)

Pale flavous, the antenne, the underside (partly), and the legs black or piceous; thorax minutely punctured,

with two large black spots ; elytra finely punctate-striate, a subtriangular sutural spot at the middle, a

small spot at the sides, and the lateral margins posteriorly, black.

Length 2 lines.

Head flavous, finely and closely punctured at its lower portion, the vertex more or less stained with fuscous ;

antenne half the length of the body, the lower five joints obscure fulvous, the rest black; thorax nearly

three times as broad as long, strongly narrowed in front, the surface remotely and finely punctured at the

sides and still more sparingly so at the disc, testaceous, with a large anteriorly-pointed piceous spot on

each side, the spot touching the base but not extending to the anterior margin, the sides with a shallow

oblique depression ; scutellum pale piceous, finely punctured, its apex truncate ; elytra slightly narrowed

posteriorly, the stric distinct and rather regular, those at the sides a little more irregularly placed, the

surface bright flavous with a subtriangular sutural spot at the middle, the point of which extends upwards

nearly to the base, and a small spot below the middle on the lateral margin, black; pygidium and the

sides of the abdominal segments pale flavous, the rest of the underside and the legs black, the femora

more or less stained with fulvous at the base.

Hab. Panama, David in Chiriqui (Champion).

Of this pretty and well-marked species fifteen specimens were obtained ; these show

no perceptible variation. ‘The eyes in the male insect are, as usual, more approximate

than in the female; the elytral spots, of which the sutural one is the largest, are placed

transversely, the smaller and lateral one being rather lower down, and there is also a

very small one (sometimes absent) on the shoulder. |

18. Scolochrus yucatanus. (Tab. XX XVIII. fig. 11.)

d. Black, a spot between the eyes, the base of the scutellum, the last abdominal segment, and the apex of the

posterior femora whitish; thorax finely punctured; elytra finely and regularly punctate-striate, red, with

a black triangular sutural spot.

Q. Head and scutellum entirely black.

Length 22-3 lines.

Head black, nearly impunctate; the eyes rather closely approached, but separated by a distinct space; a

quadrate spot between the antenne yellowish; labrum fulvous, with a black spot; antenne black, the

basal joint at the apex and the second joint also flavous; thorax about two and a half times broader than

long, strongly narrowed in front, the sides obsoletely angled at the middle, the surface entirely black,

remotely and finely punctured on the disc, the sides more strongly and closely punctate and with

an obsolete transverse oblique depression; scutellum black, the base flavous; elytra with regular and

finely punctured strie, the interstices very minutely granulate, red, the apical and sutural margins very

narrowly, and a triangularly-shaped acutely-pointed spot at the middle across the suture, black; below

black, clothed with silky white pubescence, a spot between the posterior coxa, the last abdominal

segment, and the lower margin of the four posterior femora and tibiw yellowish-white.

SCOLOCHRUS. 129

Hab. Muxico, Temax in North Yucatan (Gaumer).

This is a large-sized and robust species of which one male and five female examples

have been received. The entirely black and finely punctured thorax, the design of the

elytra, and the regular and fine punctuation of the latter, separate S. yucatanus from

the preceding species.

19. Scolochrus duodecim-guttatus. (Tab. XXXVIII. fig. 12.)

Dark brown, the thorax with the sides and three spots placed triangularly on the disc flavous; elytra strongly

punctured, the brown portion interrupted by six flavous spots (3.2.1); pygidium, abdomen, and legs

pale flavous.

Length 2~22 lines.

Head closely punctured throughout, flavous, more or Jess stained with brown, the middle with a dark impressed

longitudinal line; antenne flavous, the apical joints darker; thorax more than twice as broad as long,

narrowed from the middle to the apex, irregularly but distinctly punctured, the sides with an oblique

depression, the lateral and anterior margins, a small spot at the middle, and two oblique elongate spots

at the base (all sometimes nearly obsolete), yellow; scutellum fulvous, margined with brown; elytra

with strongly punctured striz distinctly arranged in pairs, the fifth and sixth and the eighth and ninth

rows interrupted before the middle, the dark portion consisting of narrow bands which surround the

yellow spots, the six spots placed thus—one near the suture at the base, of elongate shape, its lower

portion turned inwards, a similar one surrounding the shoulder and nearly meeting the sutural one at its

apex, another, less elongate in shape, at the middle of the basal margin, two others of more quadrate

shape, one across the suture, the other at the sides but not extending to the margin, and a transverse one

at the apex; pygidium, abdomen, and legs pale flavous, the breast obscurely piceous and finely pubescent.

Hab. Panama, David in Chiriqui (Champion).

S. 12-guttatus, although evidently allied to S. 17-guttatus, Suffr., differs from it in

the shape and position of the flavous elytral spots; of these latter the outer and inner

of those at the base are subcrescentiform and bounded above by a similarly-shaped

narrow brown band, which in its turn includes the third spot. The design of the

thorax is in some specimens very obscure; that of the elytra, however, is constant in

the nine specimens obtained.

20. Scolochrus septemdecem-guttatus. (Tab. XXXVIII. fig. 13.)

Scolochrus 17-guttatus, Suffr. Monogr. in Linn. Entom. xvi. p. 99'.

Hab. Panama, David in Chiriqui (Champion).—VeEneEzvE.a 1.

Numerous specimens of a Scolochrus obtained by Mr. Champion in Chiriqui agree

so well in their main points with Suffrian’s description of 8, 17-guttatus that I must

refer them to that species. There are, nevertheless, some slight differences present in

all these examples: the bands which surround the flavous spots are not brown but

black; the punctuation of the elytra, instead of being entirely obsolete below the

middle (as stated by Suffrian), is visible nearly to the apex; and the underside and legs

are not brown-yellow, but nearly black (the sides of the abdomen excepted). In one

or two instances, however, these last-mentioned parts are paler, and it is possible that

BIOL. CENTR.-AMER., Coleopt., Vol. VI. Pt. 1, Suppl., August 1889. g

130 PHYTOPHAGA.—SUPPLEMENT.

Suffrian had only such specimens for his type. All other characters and the pattern of

the thorax and elytra agree with the author’s description, and the Panama specimens

are, no doubt, local varieties of S. 17-guttatus.

21. Scolochrus robustus. (Tab. XX XVIII. fig. 14.)

@. Broad and robust, dark fulvous, the labrum and scutellum, the abdomen partly, and the legs flavous;

thorax very sparingly punctured ; elytra finely punctate-striate.

Length 4 lines.

Hab. Guatemata, Panzos in Vera Paz (Conradt).

In general shape this species is very broad and robust. The head is impressed with

a few fine punctures on the vertex and some deeper ones at its lower portion; the

antenne are black, the lower three joints fulvous. The thorax is suddenly narrowed

from the middle to the apex, and very minutely and sparingly punctured on the disc;

the sides are impressed with a rather deep oblique groove which is more strongly

punctured than the rest of the surface; and at the base are two obscure flavous

spots. The scutellum is entirely flavous. The elytra are entirely dark fulvous;

the region round the scutellum is distinctly raised, this elevation being followed by a

transverse depression, and there are two other deep depressions on the basal margin ;

the punctures are fine but distinct to below the middle, and deeper within the different

depressions. ‘The pygidium and the abdomen are flavous, the intermediate segments of

the latter and the breast being brown. The anterior femora are brown, and have a

flavous spot at the apex; the rest of the legs and the prosternum are also flavous.

22. Scolochrus brunneo-fasciatus.

Q., Broad and robust, flavous; head pale, the thorax dark fulvous, both minutely punctured ; elytra very finely

punctate-striate, yellow, with a broad transverse dark brown band at the middle, the band surrounding

the shoulders ; underside clothed with short golden pubescence.

3. Var. Smaller, entirely fulvous, the base of the elytra paler.

Length 3 lines.

g. Head closely punctured below the eyes, the latter approximate ; antenne with the basal two joints fulvous,

the following three joints piceous, shining, the rest black, opaque; thorax three times as broad as long,

abruptly narrowed from the middle to the apex, the surface finely and not very closely punctured ; elytra

finely punctate-striate, the stri rather regular and distinct below the middle; the underside clothed with

short golden-yellow pubescence.

Q. Broader; the elytra flavous, with a broad transverse central brown band, the anterior edge of this band

angulate near the middle, the posterior edge straight.

Hab, Panama, Bugaba in Chiriqui (Champion).

The two specimens received differ much inter se, though they evidently represent the

sexes of the same species. The male example is, no doubt, a variety in which the

basal margin of the elytra only remains yellow. In punctuation and in the golden-

yellow pubescence of the under surface the two specimens agree. The lower part of

the head in the male is also clothed with golden pubescence. S. brunneo-fasciatus

SCOLOCHRUS., 181

seems to be allied to S. flavo-fasciatus, Suffr., in coloration; the finely punctured thorax

and elytra and the uniformly pubescent under surface will, however, sufficiently distin-

guish it from that species.

23. Scolochrus imitans. (Tab. XX XVIII. fig. 15.)

2. Flavous, the head, the disc of the thorax, and the breast fulvous ; elytra strongly punctate-striate, flavous,

the middle occupied by a broad transverse dark brown band which extends to the shoulders.

Length 2 lines.

Hab. Panama, David in Chiriqui (Champion).

Closely resembling the typical form of S. brunneo-fasciatus in colour, but differing

considerably from it in sculpture. The head is closely punctured throughout, especially

on the vertex, its colour dark brown, the disc being stained with flavous; the labrum

is testaceous; the antenne are black, with the five basal joints flavous. The thorax is

remotely but more distinctly punctured than in S. brunneo-fasciatus, and has the lateral

margin broadly flavous. The elytra are coloured exactly as in S. brunneo-fasciatus, but

the punctures are deep and strongly impressed, the yellow apical portion, however,

being impunctate; the first row of punctures (following the short sutural one) extends

to half the length of the elytra and joins the suture, its anterior portion closely

approaching the second row; the following two rows are also arranged in pairs ante-

riorly, while the rows at the sides are only intact towards. the base and interrupted

lower down, the ninth row being again entire. The underside and legs are flavous,

clothed with short silvery pubescence ; the breast is darker. |

From the corresponding sex of S. brunneo-fasciatus the present insect differs, there-

fore, in the closely punctured head, the broad flavous sides of the thorax, and the strong

elytral punctuation, and also in its much smaller size and less robust form.

24. Scolochrus minutus. (Tab. XXXVIII. fig. 16.)

Black, a small spot below the eyes, the lateral margin of the thorax, the sides of the abdomen and of the

pygidium, and the tibie, partly, yellowish-white; thorax finely and closely punctured; elytra finely

punctate-striate, the anterior half fulvous, the posterior half black.

Var, Thorax entirely black, the elytra fulvous.

Length 1-14 line.

In this species, one of the smallest of the genus, the upper and lateral portions of the head are almost entirely

occupied by the large eyes (these being contiguous in the male), the lower portion being remotely punc-

tured and having a transverse yellowish spot; labrum yellowish-white; antennz two-thirds the length of

the body, black, the lower three joints yellowish beneath; thorax two and a half times as broad as long, the

sides rounded at the middle, with an oblique depression at the base, and strongly punctured, the rest of the

surface very finely and closely punctate. the interspaces extremely minutely aciculate and wrinkled, the

lateral margin narrowly flavous, the disc black; seutellum yellowish; elytra regularly punctate-striate,

the space near the scutellum almost impunctate, the anterior half fulvous, the posterior half black;

pygidium whitish, with a central black band; legs black, the base of the posterior femora and their tibie

to a greater or less degree, as well as the tarsi and the sides of the abdomen, yellowish-white.

Hab. Panama, Bugaba, David in Chiriqui (Champion).

132 PHYTOPHAGA.—SUPPLEMENT.

This very small species seems to be somewhat allied to S. memnonius, Suffr., but to

differ from it in several particulars. S. minutus is apparently subject to a good deal of

variation, not one of the five specimens obtained agreeing perfectly with each other; in

one the pale lateral margin to the thorax is almost entirely absent and the fulvous colour

of the elytra extends to two-thirds their length, and-in the variety noticed above the black

colour of the elytra has entirely disappeared. The small pale spot below the eyes is

present in all the specimens, and the strong punctuation at the sides of the thorax only

is also constant. The prosternum is strongly punctured and its apex is subtriangular.

25. Scolochyus cordovensis. (‘lab. XX XVIII. fig. 17.)

Fulvous, the antenne “he basal joints excepted) black; thorax sparingly punctured; elytra moderately

strongly puncta3s-striate, two spots at the base, placed transversely, and a narrow band below the middle

of irregular shape, black.

Length 12-2 lines.

Head fulvous, impunctate, the eyes almost contiguous in the male, more distant in the female, the intermediate

space impressed with a narrow central longitudinal groove; labrum flavous; antenne black, the two or

three basal joints fulvous; thorax about two and a half times as broad as long, the sides rounded and

widened at the middle, the surface very finely and rather closely punctured, the lateral portion more

strongly punctate and with a rather deep transverse oblique depression; scutellum flavous; elytra with

rows of rather deep punctures, the punctures at the sides and near the suture more irregularly and closely

placed, the extreme apex impunctate, each elytron with a spot on the shoulder, a rather larger spot near

the scutellum, a transverse band below the middle (not touching either margin and widened towards the

suture), and the lateral margin very narrowly, black; underside entirely fulvous, clothed with very short

yellowish pubescence.

Hab. Mexico, Cordova (Sal/é).

S. cordovensis differs in its elytral design from any other species of our region;

specimens of both sexes of it are before me.

26. Scolochrus gamma. (Tab. XX XVIII. fig. 18.)

Flavous, the breast piceous; thorax closely punctured and finely rugose, with a Y-shaped central brown mark ;

elytra opaque, distinctly punctured, the interstices finely wrinkled, a spot at the shoulder, two others

below the middle, placed transversely, and a semicircular band surrounding the scutellum, piceous. _

Var. The elytral spot fulvous, divided, and small.

Length 2-23 lines.

3. Head closely and rather strongly punctured, the entire sides occupied by the large and contiguous eyes ;

labrum bright flavous; antenne entirely flavous, extending beyond the middle of the elytra, the basal five

joints shining, the following joints finely pubescent, opaque, and slightly widened; thorax about two and

a half times as broad as long, rather suddenly narrowed from the middle to the apex, the dise with the

usual oblique depression on each side, closely and strongly punctured, the interspaces finely rugose and

aciculate, flavous, with a piceous spot placed within the lateral depression and a similarly-coloured very

distinct Y-shaped central mark; scutellum flavous; elytra regularly and rather strongly punctate-striate,

the space surrounding the scutellum with a few punctures only placed near the suture, and bounded

laterally by the short first row of punctures, the following four rows placed at nearly equal distances

from each other, but followed by a wider space, the eighth and ninth rows closely approached, the colour

similar to that of the thorax, the interstices closely and finely wrinkled and opaque, the pattern in the

plainly-marked specimens consisting of a semicircular narrow dark band extending across the suture

below the base and another band below the middle, the latter being nearly semicircular in shape, but

opposed to the anterior band in its convexity, and often composed of two nearly-connected spots, the sutural

and lateral margins also narrowly dark brown; underside and legs flavous, the breast piceous.

Hab. Muxtco, Acapulco in Guerrero (Hoge).

S. gamma might almost be mistaken for one of the varieties of S. decoratus, from

which, as well as from the other species of the genus, it differs in its finely rugose

thorax and elytra and opaque appearance. I have taken for the type the specimen

with the darkest markings, the colour in the other examples being dark fulvous, and

the markings frequently represented by spots only; the Y-shaped mark of the thorax

in all is plainly and clearly visible. The female has, as usual, the eyes separated, but

in the male they are absolutely approximate. Nine specimens.

This species is one of the most variable of the genus Scolochrus in regard to colour,

and one of which Suffrian has described no less than ten varieties. The Panama

specimens agree in having a fulvous head, thorax, and legs (the latter alone being some-

times darker), and black elytra, the anterior part of the lateral margin excepted (a

single male, however, has a white apical spot on each elytron, and a small pale central

spot on the left one only) ; but they differ slightly in sculpture from Suffrian’s description,

this author stating that “the male insect has the elytral punctures very closely placed

between the suture and the shoulder, and that scarcely any arrangement of rows is

perceptible at that portion ”—in the Panama male specimens all the rows are distinctly

separated, and visible below the middle as well as at the base, while the females agree

with the author’s description in having the rows indistinct below the middle. The

narrow white lateral margin to the basal portion of the elytra and the similarly-coloured

pygidium and sides of the abdomen are exactly as in the type; and I think that the

above-mentioned differences in regard to the punctuation are probably local.

An example from David is figured.

28. Scolochrus modestus. (Tab. XXXVIII. fig. 20.)

Black, the labrum, the sides of the thorax, the pygidium, and the sides of the abdomen white; thorax strongly,

the elytra closely and distinctly, punctured, the basal margin of the latter with a yellowish spot.

g. Of about the same small size as S. menutus. The head black, punctured at its lower portion only ; the eyes

divided by a very narrow space; two small spots below the eyes, placed transversely, and the labrum,

yellowish ; antennz black, the basal joints more or less piceous; thorax nearly three times as broad as

long, with a deep and broad oblique depression on each side, the lateral margins narrowly yellowish-white,

this colour also extending along a part of the anterior margin, the rest of the surface black, strongly and

irregularly punctured, more closely so within the depressions and anteriorly, the posterior margin perfectly

straight at its middle; scutellum scarcely longer than broad, impunctate, black; elytra strongly and

comparatively closely punctured, the strie rather irregular, the first row running nearly parallel with the

suture throughout its entire length, the two or three following rows more irregular and confused together,

those at the sides regular and scarcely interrupted, the interstices almost imperceptibly granulate, the

entire disc black and shining, the base with a small yellowish spot on each side near the scutellum; the

pygidium and the sides of the abdomen white, the rest of the underside black ; legs fulvous, the apices of

the femora obscure piceous.

Of this, according to Suffrian, extremely rare species I have lately received a specimen

from the Stuttgart Museum. The description given by Suffrian agrees in all particulars

with this example, except in some differences in colour. In the Guatemalan specimen

the pygidium is not black but yellow, and is without spots. The underside is flavous,

with the exception of the middle and sides of the breast and the centre of the inter-

mediate abdominal segments. The elytra are deeply and closely punctured, the

punctures rather regular at the sides and a little more confused and scattered on the

disc; they have the lateral margin at its posterior two-thirds, as well as three spots

(2.1), black, but there is no other mark placed near the sides (as Suffrian mentions in

his description). ‘The thorax is deeply and remotely punctured, and has two black

spots placed near the middle.

80. Scolochrus geometricus. (Tab. XX XVIII. fig. 21.)

Flavous, the breast and legs fulvous; thorax sparingly punctured, with a central and lateral brown mark;

elytra with brown or black punctured double stris, the interstices near the suture swollen and angularly

widened, and, like the apex, pale flavous.

Var. Elytra dark fulvous, the flavous spots smaller.

Length 13-14 line.

Head pale, a triangular spot at the vertex, and some narrow stripes round the eyes, dark brown; the latter

very large and subapproximate; the lower portion of the face with a few dark punctures; antenne

rather more than half the length of the body, black, the basal joint and part of the second fulvous; thorax

very short, at least three times as broad as long, the sides nearly straight, the disc rather sparingly

punctured, more closely so near the anterior margin, the surface with a deep transverse sublateral

depression, pale flavous, the sides with a longitudinal and the disc with a more or less distinct trian-

gularly-shaped brown band; scutellum raised, its apex truncate, pale brownish; elytra with deep and

closely-placed double rows of punctures, the punctures surrounding smooth and raised pale flavous spaces,

these latter defined and placed thus—a short one immediately below the scutellum, not extending to

the middle, followed by a large, elongate, and triangular space extending to below the middle, and other

similar but smaller spaces (one, elongate in shape, extending from the middle of the base as far as the

first sutural space, one, broader and more rounded, below the middle, and one small and triangular, near

the centre of the lateral margin), the entire apex and the basal and lateral margins also raised and smooth ;

pygidium flavous; the underside more or less fulvous, the sides of the abdomen, and a spot near the apex

of the femora, yellowish-white ; prosternum flat, broadly rounded posteriorly.

Hab. Panama, Volcan de Chiriqui (Champion).

This species may be easily distinguished by its curious sculpture, something like that

of several species of Pachybrachys (from which genus the differently-shaped prosternum

separates it), and its pale general coloration and small size. All the specimens obtained

seem to be females; the male probably has the eyes contiguous. One example differs

from the others in having deep black and partly confluent punctured striz, the stric

forming dark bands and surrounding the smooth yellow spaces. The apical portion

of the elytra for some distance upwards is smooth, and interrupted only by the joined

ends of the subsutural and sublateral punctured strie. In some specimens the fulvous

colour of the elytra is much more extended, the flavous spots being thus greatly

reduced in size.

31. Scolochrus quadrimaculatus. (Tab. XX XVIII. fig. 22.)

Black, some spots on the head, the labrum, and the lateral margin of the thorax yellow; thorax rugose-

punctate ; elytra closely punctate-striate at the sides, black, a large subquadrate humeral, and a round

apical spot, yellow; three spots on the pygidium, the sides of the abdomen, and part of the femora,

yellow.

Length 2 lines.

Head closely punctured, black, a small spot on each side of the vertex, the indented portion of the eyes, a Spot

at the middle, and the labrum, flavous; antenne black, the lower five joints fulvous; thorax rather more

than twice as broad as long, the sides evenly rounded at the middle, but slightly narrowed at the base

and apex, the disc with an oblique obsolete depression on each side, closely and rather strongly rugose-

punctate, black, the lateral margins narrowly flavous; scutellum black; elytra rather flattened on the

dise, scarcely more strongly punctured than the thorax, the punctuation irregular near the suture, but

arranged in close rows on the rest of the surface, the interstices scarcely raised, finely wrinkled, and but

little shining, the surface black, a humeral spot not extending to the suture, and a round apical spot,

bright flavous; below black, the anterior coxs, a spot in front and a streak at the sides of the breast, the

sides of the abdomen, and the greater part of the four posterior femora beneath, yellow, the base of the

tibie also more or less flavous ; prosternum with the apical margin yellow, and broadly rounded.

Hab. Mexico, Juquila (Sallé). A single specimen.

This species would doubtless have been included by Suffrian in the genus Metallactus ;

but for reasons already stated I prefer to place all the allied Central-American forms in

the one genus Scolochrus. Several of Suffrian’s species of Metallactus approach the

present insect very closely, though none of them come near enough to be identified

with it. Of these WM. lubricus is, perhaps, nearest allied to 8. guadrimaculatus; the

latter differs from IM. lubricus, however, in the thorax being rugosely punctured, in

the elytra being distinctly punctured nearly to the apex (instead of having

the punctures almost obsolete below the middle), and in the pygidium being black,

with yellow (not white) spots.

PACHYBRACHYS (p. 64).

Most of the American species of this genus are so inconstant in size, shape, sculpture,

and colour that unless the limit of their variation is known and understood it is almost

impossible to separate them; and many of those described by Suffrian are, no doubt,

nothing more than varieties of one or the other of these variable forms. It is the same

as in the genus Colaspis amongst the Eumolpide and Disonycha amongst the Halticide.

Fortunately, we have received long series of specimens of many of the Central-American

species, so that I am enabled to come to a definite conclusion in several instances.

Hab. Norra America ! 2 3,—Mexico, Northern Sonora (Morrison).

This species seems to have a rather wide distribution, and is said to be not uncommon

in different parts of North America. Suffrian has given a detailed description; but

several specimens obtained by the late Mr. Morrison amongst others of the normal form

show some very obscure red markings at the sides of the thorax and on the elytra.

Examples thus coloured resemble P. hematodes, from which they differ, however, in

shape and other details; this red coloration seems to be peculiar to a greater or less

degree to the few pubescent species of Pachybrachys at present known.

1 (s). Pachybrachys thoracicus. (Tab. XX XVIII. fig. 23.)

Cylindrical, black, pubescent ; thorax finely punctured, the posterior half of the sides bright red ; elytra strongly

punctured, the interstices subcostate near the apex.

Length 2 lines.

Hab. Mexico, Pinos Altos in Chihuahua (Buchan-Hepburn).

The only, apparently female, specimen I have for examination differs sufficiently from

P. pubescens to treat it as distinct. P. thoracicus is of an entirely black colour, with

the exception of a narrow basal margin to the elytra and the posterior half of the sides

of the thorax (in the shape of a broad triangular space extending inwards to the middle

of the base), these parts being red; the surface of the thorax is closely and finely rugose-

punctate and clothed with long whitish hairs; the elytra are similarly pubescent, but

much more strongly and less closely punctured, the punctures being arranged here and

there in indistinct rows, the interstices being also minutely punctured and becoming

slightly convex towards the apex; the underside and legs are black and pubescent, the

tibiee at the base being very obscurely stained with fulvous. In P. pubescens the elytral

punctuation is much finer and shows no trace of regular arrangement. P. analis, Lec.,

seems to be an allied species, but is stated to have a red margin to the elytra.

PACHYBRACHYS. 137

1 (c). Pachybrachys semibrunneus. (Tab. XXXIX. fig. 1.)

Black ; above obscure fulvous, finely pubescent ; thorax very closely and finely punctured, clothed with silvery

pubescence; elytra similarly pubescent, and as closely but more strongly punctured, the interstices sub-

rugose ; legs with yellow spots.

Length 14 line.

Head closely punctured, and clothed with silvery pubescence, blackish, a narrow stripe near the eyes, and some

spots below the middle, obscure fulvous; antennz extending to beyond the middle of the elytra, black, the

lower five joints more or less fulvous; thorax about twice as broad as long, scarcely narrowed in front,

the sides rather strongly deflexed, the disc very closely and rather strongly punctured, clothed with

comparatively long silvery hairs; scutellum black; elytra subcylindrical, more deeply and strongly

punctured than the thorax, the interstices irregularly rugose, but with scarcely any traces of longitudinal

coste, the surface obscure fulvous, and pubescent like the thorax, the shoulders with a black spot;

pygidium black, with two yellow spots; underside black, clothed with long whitish hairs, the last

abdominal segment with a yellow spot on each side; legs black, the femora with the base and an apical

spot, and the base of the tibie, fulvous.

Hab. Mexico, Durango city (Hége).

Narrower and more cylindrical in shape than P. pubescens (Oliv.); the entire upper

surface very obscure fulvous (in certain lights, however, some darker spots are visible

on the elytra). A single specimen.

Pachybrachys rubronotatus (p. 65).

To the Mexican locality given, add :—Zacualtipan in Hidalgo (Hége).

The single specimen, a female, obtained by Herr Hége does not differ much from the

type, except in colour; the thorax is more transversely shaped and the red colour

prevails along the entire anterior margin as well as at the sides, and the punctuation is

rather stronger ; the elytra are entirely black, with the exception of the basal margin

near the scutellum ; and the femora are only fulvous at their extreme base and have no

apical spot. The close and deep punctuation of the elytra is interrupted here and there

by longitudinal irregular raised coste as in the type.

Pachybrachys varicolor (p. 65).

To the locality Mexico, add:—Ciudad in Durango (Hége).

Herr Hoge obtained ten specimens of this apparently rare and variable species. In

most of these the black colour of the elytra predominates; but sometimes the elytra

are flavous, the punctures only being black and arranged in close longitudinal rows ;

the extreme apex is always flavous, and generally the two marginal interstices also.

Specimens with yellow elytra frequently have the thorax spotted with that colour.

Pachybrachys bajulus (p. 66).

in Guerrero, Orizaba (H. H. Smith); Guatemaa, San Joaquin in Vera Paz, Calderas

(Champion).

138 PHYTOPHAGA.—SUPPLEMENT.

P. bajulus being evidently a very variable species, I have ventured to refer all the

specimens from the above localities to it,.more especially as they have most of the

principal characters in common. The thorax has a semiangular (not rounded) lateral

margin and a closely punctured surface, the punctures interrupted by small yellow

spots which often form themselves into two more or less distinct yellow lateral stripes

and a shorter central one. The elytral sculpture it is almost impossible to describe,

scarcely two specimens being alike in this respect, and in some cases one elytron is

differently punctured to the other; as a rule, however, the entire lateral portion is

impressed with black semiregular rows of punctures, and between these short yellow

spots and stripes are visible, amongst which a small raised spot is particularly promi-

nent near the suture at the middle. The underside and legs are generally black. The

pygidium has four yellow spots, and the last abdominal segment is entirely of that

colour. Specimens occur in which the black punctures and lines of the upper surface

are replaced by brown.

6 (4). Pachybrachys minutus. (Tab. XXXIX. fig. 2.)

Black; thorax closely punctured, flavous, with three broad black bands, the middle one divided anteriorly ;

elytra flavous, this colour interrupted by deep black punctured irregular strie; pygidium black, with

four yellow spots; underside and legs black, the last abdominal segment and the femora spotted with

white.

Length 2-1 line.

Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith).

This very small species, of which several specimens were obtained, seems to be most

nearly allied to P. bajulus; it differs from it, however, in the entirely black antenne,

the differently-marked thorax, different sculpture of the elytra, and the much smaller

general size. The head is black, very closely punctured, and has six bright flavous

spots, of which two, obliquely shaped, are placed on the vertex, two in front of the

eyes, and two others within their emargination; the lower portion of the epistome is

also more or less flavous. The antenne extend to about two-thirds the length of the

elytra, and are black, with the exception of the lower joints, which are slightly tinged

with piceous beneath. The thorax is rather closely and strongly punctured, with evenly

rounded sides, and the bright flavous ground-colour is divided by a black band at the

sides, including a small yellow spot, and a central band divided anteriorly by a narrow

flavous stripe; the basal margin has a narrow flavous stripe in front of the scutellum,

the latter being entirely black. The elytra seem to differ from those of P. bajulus in

having more yellow longitudinal raised interspaces, which are even visible at the base

between the shoulder and the scutellum; the deep black punctured strize interrupt in

many places the yellow portion, dividing it into unequal stripes, and they often unite to

form spots near the apex and at the sides. The underside is entirely black, with the

exception of a yellow spot at the sides of the last abdominal segment. The legs do not

seem to differ in colour from those of P. bajulus. The markings of the head and thorax

are exactly similar in the three specimens obtained.

Pachybrachys scenicus (p. 66).

To the locality Mexico, add :—Cuernavaca, Juquila (Sai/é), Amula, Omilteme, Chil-

pancingo, Xucumanatlan in Guerrero (H. H. Smith).

P. scenicus is not easy to distinguish from the darker varieties of P. labyrinthicus,

and the two species seem to me to be somewhat doubtfully distinct. Both have an

elongate-triangular, raised, smooth space at the suture near the middle, this space being

rather shorter in the present insect than in P. labyrinthicus (this in itself is of no

importance); the thorax does not seem to differ much in the two species, and is simi-

larly marked in both (the markings being often obsolete in the paler specimens of

P. labyrinthicus) ; but the sculpturing of the elytra seems certainly to differ considerably.

In P. scenicus the black punctured striz are much more irregular and often interrupted

by smooth yellow narrow spaces, so that it is almost impossible to convey a correct

impression by a description of their direction. Suffrian gives the elytra as black and

speaks of yellow spots; but it would be better to describe the elytra as yellow with

black punctured strie, the latter placed thus :—two short curved striz surrounding the

scutellum, the outer one connected with the third and ninth stria at the apex and

including an elongate-triangular smooth space near the suture, and both abbreviated

behind; the fourth and fifth strie closely approached and shorter than the preceding

ones; the next pair of strie interrupted at and below the middle; the outer one

parallel to the lateral margin, at some distance from it, and enclosing a smooth yellow

space which extends from the shoulder to the apex, and is continued to the suture.

These black striz are often united, forming elongate black markings here and there ;

the underside for the greater part is black; the legs are fulvous, the femora with a

black mark. P. labyrinthicus is generally much paler; it also has the elytral strie

more regular (although nearly similar in direction to those of P. scenicus), and the

triangular smooth sutural space longer and carried lower down. I also refer some

smaller specimens from Omilteme and Xucumanatlan to the present species; some of

them have the thorax much more closely punctured, but others are intermediate in

this respect.

7 (a). Pachybrachys inclusus. (Tab. XXXIX. fig. 3.)

Black ; above yellow; the thorax with three black, elongate, partly divided, stripes; elytra with closely

approached deep-black strie, often connected, forming three distinct black spots at the sides, and enclosing

a rounded smooth yellow space near the suture at the middle; pygidium yellow, scarcely spotted; legs

fulvous, the femora with a dark spot.

140 PHYTOPHAGA.—SUPPLEMENT.

P. inclusus is closely allied to P. scenicus and its allies, but it cannot well be regarded

as a variety of either, the eight specimens I have for comparison all agreeing in the

following particulars:—The thorax is rather more strongly punctured (though the

black markings are very similar); the elytra have the black strie more frequently

united, forming black markings, the elongate-triangular space near the suture replaced

by a nearly round one (similar to that present in P. irregularis), the strie at the sides

united in three places, forming three deep black spots, the strie below the scutellum

frequently joined, by which another black mark is formed, and the immediate space

surrounding the scutellum often closely and irregularly impressed with black punctures ;

and the pygidium (its lower edge excepted) and the sides of the last abdominal segments

are yellow. The legs agree in colour with those of P. scenicus. P. inclusus is a larger

and more robust insect than P. irregularis, and has the markings of the thorax and of

the elytra deep black and the strie more frequently united; our figure, which is taken

from a specimen with the pale spots rather more conspicuous than in the others, will

convey a better idea of the differences between the two species.

Pachybrachys irregularis (p. 67).

To the localities given, add :—Mexico, Colima city (Hége), Tepetlapa, Chilpancingo,

and Amula in Guerrero, Orizaba (H. H. Smith); Guatema.a, Cerro Zunil, San Isidro |

(Champion).

This seems to be a most variable species, of which it is difficult to fix the limit.

Suffrian describes the thorax as being closely punctured, the space surrounding the

scutellum irregularly, the rest of the elytral surface rather regularly, punctured; the

elytra with a more or less ovate (not elongate), smooth, and raised space near the

suture at the middle of each (this space being more rounded in shape than in P. lady-

rinthicus); the underside for the greater part black; and the pygidium and legs more

or less fulvous. The author speaks further of a transverse black spot near the apex of

the elytra, which in the otherwise typical specimens that have come under my obser-

vation is absent. The description, however, if carefully compared, agrees very well

with the specimens obtained in Mexico ; but nearly all those received from Guatemala

differ in the following particulars:—They are smaller; the thorax is much less closely

punctured, and has on each side a nearly smooth, slightly raised space; and the elytra .

have the space surrounding the scutellum generally with two short curved rows of

impressions (not irregularly punctured), and the rest of the punctuation regular (but the

punctures much more distantly placed than in the typical specimens), and have also a

small nearly black shoulder-spot, and frequently a dark transverse band of variable

width near the apex (which agrees with Suffrian’s description).

I would certainly have looked upon these Guatemalan specimens as distinct from

P. irregularis, if we had not several examples with an intermediate form of sculpture.

PACHYBRACHYS. 141

8 (a). Pachybrachys forreri. (Tab. XX XVIII. fig. 24.)

Black; thorax very closely punctured, the sides, and three spots placed triangularly, yellowish-brown; elytra

closely punctured, the posterior portion costate, the base and the apex, and two spots placed transversely

at the middle, yellowish.

Length 13 line.

Head very closely punctured, black, a narrow margin surrounding the eyes, a spot at the middle, and the

labrum, dark yellow ; antenne more than two-thirds the length of the body in the male, black, the lower

five joints fulvons: thorax rather convex, with strongly rounded sides, extremely closely punctured, the

interspaces here and there rugose, with a more or less distinct central longitudinal raised line, the surface

black, with the lateral margins broadly, part of the anterior margin, the raised middle line (sometimes

widened into a triangular space), and two small spots at the sides, dark yellow; scutellum with a few

punctures, black, its apex truncate; elytra with deep and very closely arranged punctures, the interstices

in part longitudinally costate, much more regularly so towards the apex than at the base, a smooth rounded

space placed below the middle near the suture, the base (in the shape of a broad transverse band

extending downwards at the sides), a spot at the apex, another at the sides below the middle, and the

raised space near the suture, dark yellow; pygidium yellow, with the margins and a central longitudinal

line black ; underside and legs black, the femora with the base and a spot at the apex, and the last

abdominal segment, yellow.

Hab. Mexico, Ciudad in Durango (Forrer), Ventanas in Durango (Hoge).

This is a well-marked and somewhat easily recognized species, quite distinct from

any other known from our region. The amount of yellow on the thorax varies (in one

specimen the middle spot occupies a broad triangular space), but is regularly placed.

If the yellow of the elytra is taken for the ground-colour, the black forms a broad

common subquadrate patch, which sends a short branch upwards and two longer branches

sideways, the latter extending to the lateral margin; the arrangement of the punctures

in rows is very indistinct owing to the close punctuation.

8(s). Pachybrachys durangoensis. (Tab. XX XVIII. fig. 25.)

Subcylindrical, dark brown or obscure fuscous ; thorax extremely closely and finely punctured, lighter brown

with obscure darker markings; elytra flavous, closely impressed with dark brown punctures irregularly

placed, the interstices finely wrinkled; legs light brown, with dark markings.

Length 2-22 lines.

Hab. Mexico, Ventanas in Durango (/ége).

This Pachybrachys, of which we have received two specimens, may be recognized by

its opaque obscure fuscous colour and extremely closely punctured head and thorax,

and by the absence of all longitudinal coste to the elytra. The head has the usual

paler rings round the eyes, and some flavous spots on the lower portion; the antenne

(2) do not extend to the middle of the elytra, and are dark fulvous, with the

terminal joints darker. The thorax is about twice as broad as long, the sides being

rounded at the base but distinctly narrowed towards the apex; the surface is

extremely closely punctured, and very sparingly clothed with grey pubescence, and

is light brown in colour, with an obscure (Y)-shaped brown mark on the middle of

the disc. The ground-colour of the elytra is flavous, as well as the extreme and

narrowly-raised basal margin; almost the entire surface is irregularly impressed with

142 PHYTOPHAGA.—SUPPLEMENT.

dark brown punctures, which only at the extreme apex show traces of arrangement

into rows; the interstices are finely wrinkled throughout, the wrinkles very slightly

raised above the punctures; from the basal margin two very narrow and indistinct

flavous raised lines extend a little way downwards. The pygidium is dark brown, and

clothed with long greyish pubescence. The underside and legs are pale brownish, and

the femora have a piceous ring-shaped mark.

8 (c). Pachybrachys maculicollis. (Tab. XXXIX. fig. 4.)

Black ; above yellowish-brown; the head with four, the thorax with five partly connected black spots; elytra

strongly and rather irregularly punctured, the punctures black, the interstices scarcely raised, three spots

at the sides, and three others near the suture, black; pygidium and legs spotted with yellow.

Length 2 lines,

2. Head flavous, finely punctured, the vertex, an elongate-triangular spot at the middle, and two small spots

at the base of the antenne, black; antenne scarcely half the length of the body, the lower six joints

fulvous, the others black; thorax about twice as broad as long, the sides narrowed towards the apex, the

surface rather irregularly and finely punctured, but with some smooth yellow spaces here and there, and

with three spots placed triangularly at the middle of the base and one on each side (which, if connected,

form the usual (¥)-shaped mark), black; scutellum black; elytra pale brownish like the thorax, the

punctures black and irregularly distributed, but forming here and there double rows, of which one may

be distinguished near the suture and two others at the sides, the outer row connected with the three

black lateral spots (one placed at the shoulder, one at the middle, and one near the apex), the spots near

the suture more or less elongate in shape and placed slightly lower than the lateral ones, the disc and the

sides with a single longitudinal costa; pygidium black spotted with yellow, this colour extending to the last

abdominal segment; legs fulvous, the femora having the usual black mark, followed by a bright yellow spot.

Hab. Mexico, Milpas in Durango (orrer).

In this species, females only of which are before me, the elytra are devoid of the

numerous longitudinal raised cost found in most Pachybrachys at the sides and apex,

two only being visible; and this form of sculpture places P. maculicollis in Suffrian’s

fifth group. From the closely allied species described by Suffrian it may be known

by its yellowish-brown upper surface, the five distinct spots on the thorax, and the

irregular elytral sculpture. If the latter is carefully examined, three double rows of

punctures may be seen, between which the interstices are slightly raised; the outer

rows of these punctures are united at a little distance from the apex; the other portion

of the surface is irregularly impressed with black punctures; the black lateral and

discoidal markings are plainly visible to the naked eye, forming three irregular,

transverse, broken bands as in P. scenicus, P. irregularis, and others. P. maculicollis,

however, differs from these species in having the lateral rows of punctures much more

regular, and the thorax is marked with bands, not spots.

Pachybrachys labyrinthicus (p. 67).

To the locality Mexico, add:—Ciudad in Durango (forrer), Chilpancingo, Amula,

Xucumanatlan, and Acapulco in Guerrero (Hoge, H. H. Smith), Mexico city (Flohr).

An examination of the numerous specimens since received from the above localities

PACHYBRACHYS. — 148

seems to prove the validity of P. labyrinthicus. The colour is pale yellowish above ;

_ the thorax has the usual markings much less conspicuous than is generally the case, a

' small dark brown spot in front of the scutellum alone being prominent ; and the elytra

have the smooth subsutural space drawn out into an elongate triangle (this space not

being ovate or rounded as in P. irregularis). P. labyrinthicus seems to be constant in

colour and sculpture, and it differs also from P. irregularis in having a short double

row of punctures surrounding the scutellum (instead of the corresponding space

irregularly punctured as in the allied species). The specimens from Ciudad are much

darker, and have the interstices between the punctures marked with streaks of black,

the punctured rows themselves often becoming nearly united; these examples cannot

be satisfactorily separated from P. labyrinthicus.

Pachybrachys punctatissimus (p. 68).

To the Mexican localities given, add:—Jalapa (Hége).

To the description of this species I may add that the interspaces between the punc-

tures of the thorax are unevenly rugose or wrinkled, and, therefore, the sculpture is

quite different from that of most other species of the genus; the thorax also has a

more or less distinct narrow raised central ridge extending from the anterior to the

basal margin; the elytra are nearly white, and everywhere impressed with brown

punctures, which near the suture and apex aggregate and form short stripes, and are

without longitudinal striz or coste.

Pachybrachys umbraculatus (p. 69).

To the Mexican locality given, add :—Saltillo in Coahuila (Dr. Palmer).

This is evidently a good species, of which our figure is a good representation. The

sixteen specimens received from Saltillo scarcely show any variation; the thorax is

proportionately longer than in most other species of the genus, and its markings are

nearly always only indicated by obscure dark fulvous or piceous spots.

14 (a). Pachybrachys flavescens. (Tab. XXXIX. fig. 5.)

Broad and robust, pale flavous, the sides of the breast darker; thorax irregularly and subremotely punctured ;

elytra with regular rows of dark and deep punctures, the space between the second and fourth rows

triangularly widened. .

Length 2 lines.

Head entirely pale flavous, finely but not very closely punctured ; the eyes widely separated; antenna nearly

as long as the body, flavous, the apical two joints more or less black ; thorax scarcely twice as broad as

long, of about half the length of the elytra, the sides obliquely narrowed from below the middle to the

apex, the disc irregularly but not very closely punctured, entirely flavous ; scutellum flavous, margined

with piceous; elytra of the same colour as the thorax, with eleven nearly regular rows of large black or

brown punctures—of these three short rows are placed round the scutellum, the first row straight, the

second and third rounded, the latter after curving round towards the suture at the middle running parallel

rows abbreviated before the apex, the following rows nearly regular and parallel, and their interstices but

moderately convex ; pygidium and the underside pale flavous, the sides of the breast and the abdominal

segments more or less dark brown; legs pale fulvous, the femora with a whitish spot; the female with a

narrow triangular fovea on the last abdominal segment.

Hab. Mzxico, Rincon in Guerrero (H. H. Smith).

Of this rather large and plain species two specimens, apparently male and female, were

obtained by Mr. Smith. Except for the occasionally confluent punctures of the elytra,

which form short brown streaks here and there, the upper surface is entirely of a uniform

flavous colour; in one example the sixth, seventh, and eighth rows of punctures are

interrupted by a raised smooth space at the middle, which may be accidental, as it is

absent in the other. P. flavescens agrees with P. umbraculatus in the arrangement of

the elytral punctuation ; but differs in the much more robust and broader shape, the

more evenly punctured thorax, and the colour of the underside, and also in the almost

entirely flavous antenne.

16 (a). Pachybrachys brunneo-maculatus. (Tab. XX XIX. fig. 6.)

Head and thorax testaceous, the latter very finely punctured and obscurely spotted with brown ; elytra with

finely impressed, partly geminate, rows of punctures, flavous, the interstices spotted with brown, the

brown markings forming short longitudinal bands ; underside and legs dark brown, spotted with flavous.

Length 13-14 line.

Head entirely testaceous, or obscurely spotted with fulvous on the vertex, sparingly impressed with small and

at the middle closely-approached punctures; eyes widely separated in both sexes (rather more contiguous

in the male); antenne nearly as long as the body in the male, the basal two joints fulvous, the others

pale at their base; thorax proportionately short, more than twice as broad as long, still broader in the

female, the sides with an oblique depression, the surface finely and rather closely punctured, pale flavous

or testaceous, a V-shaped obscure brown mark on the disc and a spot on each side ; scutellum raised, flavous,

its apex truncate ; elytra with the basal portion slightly raised, bounded on each side behind by a transverse

oblique depression, the basal margin strongly thickened (especially round the scutellum), the punctures dark

brown and rather regularly but distantly placed in more or less distinct double rows, which are joined at

some distance from the apex, and somewhat interrupted by irregular punctures placed within the oblique

postbasal depression, the rows at the sides often sinuate and interrupted by extra punctures, the apex

entirely impunctate, the interstices forming longitudinal stripes, partly flavous and partly dark brown, the

short dark brown stripes being generally more distinct at the suture below the scutellum, at the middle of

the base, on the shoulder, and within the oblique depression, some other brown markings being visible below

the middle and along part of the punctured strie ; pygidium flavous, with a darker margin ; underside and

legs brown ; abdomen more or less flavous at the sides ; prosternum longitudinally depressed in the middle,

its base broadly subtriangular.

Hab. Panama, Volcan de Chiriqui (Champion).

The punctuation of the elytra in P. brunneo-maculatus resembles somewhat that of

P. reguiaris, but it is not so clearly defined. The elytra have also a similar transverse

depression extending across the middle, so that the basal portion appears to be raised ;

besides this, the basal margin, especially the part surrounding the scutellum, is strongly

thickened ; the space below this is irregularly punctured, but the rest of the surface is

impressed with rather regular rows of punctures which are, however, often closely

approached, the interstices thus appearing narrower in places. The entire surface of

the elytra is varied with longitudinal flavous or brown markings, a character that will

principally distinguish P. brunneo-maculatus from its allies. The ten specimens

obtained do not show any variation of importance.

16 (8). Pachybrachys juquilensis. (Tab. XX XIX. fig. 7.)

Dark brown below ; above flavous; thorax extremely closely and finely punctured, with obscure flavous lateral

and central markings; elytra with deep and regular rows of punctures at the sides, the interstices costate,

a spot on the shoulder, two short transverse bands at the sides, and a spot near the scutellum, dark brown

or black; pygidium flavous; legs fulvous, spotted with pale yellow.

Length 1? line.

Hab. Mexico, Juquila (Hége).

P. juquilensis seems most nearly allied to P. brunneo-maculatus, from which it differs

in the thorax being very closely punctured and also devoid of the oblique lateral groove

(distinctly visible in P. brunneo-maculatus). The entire upper surface is opaque and of

a pale flavous colour. ‘The fine and pale brown punctures of the thorax are arranged in

such a way as to leave at the base (in plainly-marked specimens) a narrow lateral flavous

line and a short central similar stripe. The elytra are very regularly and deeply punc-

tured almost throughout, only a small sutural space being (as usual) more irregularly

punctate; the three lateral transverse spots and an oblique mark surrounding the

scutellum are very distinct and of dark brown or nearly black colour, these markings

being much more decided and plainly visible than in any other species of the genus

known to me. The pygidium is flavous (sometimes with an obscure central stripe), the

underside is brown, and the femora are fulvous with the usual whitish spots.

The distinct spots of the elytra being placed on a pale opaque ground-colour and the

closely and finely punctured thorax will assist in the recognition of the present insect,

of which both sexes were obtained by Herr Hége at Juquila.

Pachybrachys cribellatus (p. 70).

Pachybrachys uniformis, huj. op. p. 70.

To the localities given, add:—Mexico, Teapa in Tabasco (H. H. Smith).

A close examination of many more specimens lately received seems to prove that

P. uniformis, Jac., cannot be considered as distinct from P. cribellatus, Suffr. The

species varies much in size ; the male insect, which was unknown to Suffrian, does not

differ materially from the female. The thorax of P. cribellatus is stated to be “ rather

closely punctured ”: I must apply the term “extremely closely” to our insect, which

in all other respects agrees with Suffrian’s description.

19 (a). Pachybrachys salle#i. (Tab. XXXIX. fig. 8.)

obscure lateral marks flavous; elytra irregularly punctured, with two indistinct discoidal cost and a

narrow sublateral one flavous, the disc with two, the sides with three, indistinct brown spots.

Length 12-2 lines.

Hab. Muxico, Oaxaca, La Parada (Sal/é).

The sculpture of the elytra of P. sall@i would seem to place the insect in Suffrian’s

sixth group, the nearest allied species being, apparently, P. cribellatus. From this

latter P. sall@i differs in the colour of the underside and in several other particulars.

The head is closely covered with brown punctures, but with a narrow margin round

the eyes bright flavous ; the antenne do not extend to the middle of the body, and are

black with the basal four or five joints fulvous. The thorax is strongly transverse in

shape, and the sides are much deflexed, so that the lateral margins cannot be seen

when the insect is viewed from above; these latter are somewhat prominent behind the

middle but oblique towards the apex; the surface is crowded with brown punctures,

which leave one central and two obscure lateral marks of the flavous ground-colour

(these markings are very obscure and better seen without a lens). The scutellum is

black or brown. The elytra are more strongly punctured than the thorax, and the

punctuation for the most part is irregular; two raised longitudinal narrow flavous

spaces are visible between the shoulder and the suture, and there is a similar costate

space near the lateral margin; the interior of all the punctures is dark brown in colour,

although the ground-colour may be described as flavous; and there are about five very

obscure brown spots, of which three are placed along the sides and two on the disc.

The pygidium is yellow, with its basal margin black; the underside is black (in some

specimens of a dark brown colour), spotted with yellow at the sides of the abdominal

segments ; the legs are dark fulvous, with the apex and base of the femora more or less

flavous.

The absence of well-defined longitudinal coste on the posterior portion of the elytra

(these being present in so many species of Pachybrachys) will make P. sallei compa-

ratively easy of recognition ; and the rusty-brown colour of the upper surface, interrupted

by the obscure paler spots, the very closely punctured thorax, and the dark underside

and fulvous legs will further assist in its determination.

Female examples only have been received.

Pachybrachys hepaticus (p. 71).

To the localities given, add :—Mexico, Amula and Tepetlapa in Guerrero (ZH. H.

Smith); Guatemaa, Las Mercedes, Cerro Zunil (Champion).

P. hepaticus seems subject to so much variation in colour and in the pattern of the

elytra that it is somewhat doubtful whether all the specimens from the above localities

are really referable to it. Suffrian’s description of Melsheimer’s species does not agree

with most of the Guatemalan examples, these being rather more robust and cylindrical,

PACHYBRACHYS. 147

of darker colour, and different elytral sculpture; we have, however, some few inter-

mediate specimens, which show that no great stress can be laid on these differences.

The elytra in the Guatemalan insects, and also in one from Amula, have a nearly black

round spot placed across the suture near the apex, this spot being bounded above by a

narrow zigzag flavous spot (which sometimes extends laterally or is composed of several

spots partly united), and they have other bright and raised flavous spots placed below

the shoulder at the sides and round the scutellum ; in the type their entire surface is

paler, the flavous stripes and spots are less prominent (of a round dark sutural spot

Suffrian says nothing), and the surface more evenly punctured. In the Guatemalan

specimens the elytral punctuation is also partly arranged in double rows and interrupted

in front of the flavous spots, and the thorax is mottled with flavous and dark brown ;

it is possible that these are really specifically distinct from P. hepaticus, but in the

absence of sufficient material for comparison it is better to treat them as a local

variety.

20 (a). Pachybrachys mexicanus. (Tab. XX XIX. fig. 9.)

Black below; above pale greyish, closely punctured throughout; elytra without longitudinal interspaces, a

spot on the shoulder, two or three others placed obliquely near the apex, and an elongate spot near the

suture below the middle, black.

Length 2-1 line.

Hab. Mexico, near the city (H. H. Smith).

P. mexicanus although very closely allied to P. hepaticus differs from that species in

the following details:—The general shape is less cylindrical and robust, which is

especially apparent in the elytra; the latter are evenly and closely punctured through-

out, without any traces of smooth longitudinal spaces except at the lateral margin, this

part remaining narrowly impunctate and nearly white in colour, and the spots are also

different in shape and position. The eyes are unusually widely separated in both sexes ;

the intraocular space is very closely and deeply punctured, and pale greyish in colour

with some obscure dark markings. The antenne extend a little beyond the base of the

thorax in the male, and resemble those of P. hepaticus. The thorax is less cylindrical

than in P. hepaticus, narrowed at the sides, with an obscure lateral depression above,

and extremely closely punctured. The elytra are rather flattened along the suture, and

a little less closely punctured than the thorax (especially near the apex); near the apex

and close to the suture is an elongate blackish spot, and at the sides are three others

(more or less distinct) placed obliquely above each other, a similar spot being placed at

the shoulder and sometimes another near the scutellum ; the lateral margin is accom-

panied by a narrow smooth whitish space. The underside and legs are blackish, with

a yellowish spot on the last abdominal segment and another at the apex of the femora.

The four specimens obtained agree closely with each other.

20 (zs). Pachybrachys marmoratus. (Tab. XXXIX. fig. 10.)

Obscure fulvous, mottled with black, pubescent; thorax very finely and closely punctured, with four very

obscure black bands; elytra finely and semiregularly punctate-striate, pubescent, with two obscure

longitudinal black bands.

Var. Thorax and elytra nearly black, the sides and apex of the latter obscure flavous.

Length 2 lines.

Head closely punctured, fulvous, a spot at the middle and the vertex, partly, black ; antenne short, the lower

six joints fulvous, the two basal ones stained with black above, the terminal joints entirely black ; thorax

twice as broad as long, the sides nearly straight and gradually narrowed in front, the posterior angles

acutely pointed, the surface closely impressed with fine but deep oblong punctures, leaving a smooth

central slightly raised line, and pale fulvous or ferruginous in colour, a longitudinal band on each side and

another near the middle black, these bands partly obsolete and forming a M-shaped mark; scutellum

narrowly transverse, fulvous, margined with black; elytra with irregular rows of fine punctures—the

three nearest the suture more widely separated, the others closely approached in threes,—the interstices

minutely punctured, the surface opaque, pale fulvous, and clothed with short pubescence, the sides and

the disc with a broad obscure black band of unequal width; pygidium flavous; underside black, the

abdomen more or less fulyous at the sides; legs fulvous, the femora with a black spot, the tibiz more or

less black at the apex.

Hab. Mexico, Pinos Altos in Chihuahua (Buchan-Hepburn).

It is possible that this insect is closely allied to or even identical with P. analis, Lec.

20 (c). Pachybrachys immaculatus.

Black; above pale yellowish-grey ; head and thorax rather closely punctured, the latter with obsolete pale

brownish bands; elytra semiregularly punctured, without markings; pygidium and last abdominal

segment pale yellowish ; femora darker in the middle.

Length | line.

Hab. Mexico, near the city (H. H. Smith), La Parada (Salié).

I cannot refer the two specimens obtained by Mr. Smith and a third from the Sallé

collection to P. posticus, P. hepaticus, or P. pinguis, Suffr.: in these species the

antenne scarcely extend beyond the base of the thorax, and their apical joints are

thickened; in P. immaculatus they are of half the length of the body, and their apical

joints although slightly thickened are elongate, not short. The thorax is punctured in

such a way as to leave two narrow pale divisions between the darker portions in the

shape of yellowish basal spots; the elytral punctuation is arranged, except near the

suture, in semiregular rows almost throughout, and the entire surface is of a pale

greyish or greenish-yellow colour without any spots. ‘These differences will help to

distinguish P. immaculatus from its allies, including P. mexicanus; the latter has

much more closely and irregularly punctured elytra than P. immaculatus.

Pachybrachys bifasciatus (p. 71).

Var. Elytra black, a spot near the basal margin, the lateral margin anteriorly, two spots placed transversely

across the middle, and the apex, flavous.

Hab. Mexico, Cordova (Sallé), Atoyac in Vera Cruz (H. H. Smith).

This variety, at first sight, seems to be referable to another species, as its system of

coloration is totally different from the banded type; I am, however, unable to find any

PACHYBRACHYS. 149

other characters of separation. P. bifasciatus might perhaps have been placed equally

well in Scolochrus, with some of the small species of which it quite agrees in shape and

sculpture. The variety differs from the type in having the elytra black with five or six

fulvous spots (the remnants of the light-coloured raised spaces of the type); of these

the middle ones are placed obliquely and transversely across the centre and a larger

one at the apical angle of each elytron.

Pachybrachys laticollis (p. 72).

To the Mexican localities given, add:—Chilpancingo (Hége), Amula in Guerrero

(H. H. Smith). :

P. laticollis is apparently a rather doubtful species. The description was taken from

a male specimen from San Gerdnimo, this having the terminal joint of the antenne

distinctly elongate and widened ; and other examples of the same sex, obtained subse-

quently at Chilpancingo, also possess this character, which seems to be a constant one.

The thorax, which is proportionately wide and rather strongly rounded at the sides at

the middle (forming a continuous outline with the sides of the elytra), is extremely

closely punctured, and is either black with the margins narrowly and an irregular

number of small spots flavous, or brown with similar pale spots and three darker longi-

tudinal bands ; the elytra are flavous, mottled with dark brown, irregularly and closely

punctured near the suture, and longitudinally costate at the sides and apex. ‘The

temale has simple antenne. Specimens from Vera Cruz are entirely obscure dark

brown above ; but being all females I am not able to say whether they belong to this

or to an allied species. P. laticollis can therefore at present only be distinguished

from its allies by the structure of the antenne in the male sex, and the broad and

extremely closely punctured thorax; the pygidium has four yellow spots.

It is impossible to refer the numerous specimens from the above localities with

certainty to the present or to either of the numerous similar closely-allied species

described by Suffrian without comparing the types. This author’s description of

P. femoratus seems, however, to agree best with the insects before me; they almost

entirely resemble P. laticollis, but are for the most part smaller, and the male differs

from the corresponding sex of that species in the apical joint of the antenne not being

dilated, and also in the thorax being less broadly shaped. The colour is extremely

variable, either the brown, black, or flavous predominating ; the thorax is crowded with

small punctures and irregularly marked with very small flavous spots, and generally

has three broad obsolete dark bands placed at the sides and middle (as in so many other .

species of the genus) which sometimes occupy almost the entire disc; the elytra have

the sutural portion to below the middle and laterally to half their width irregularly

punctured, the rest of the surface (especially towards the apex) being impressed with

sinuous longitudinal rows of punctures between which the interstices rise as narrow

flavous spaces; the pygidium is yellow, with the margins and a central stripe darker ;

the underside varies from dark brown to nearly black, with the last abdominal segment

generally flavous; the base and apex of the femora are flavous, the rest of the legs

nearly black. P. spumarius, Suffr., from North America, seems to be almost identical

with P. femoratus. In regard to the elytral punctuation of P. femoratus, or rather to

that of the specimens I refer doubtfully to this species, ] may add that in all our

examples the irregularly punctured area near the suture is bounded below by a small

smooth transversely-shaped space which interrupts the first two rows of punctures (of

this Suffrian makes no mention).

Two specimens from Guatemala received from the Stuttgart Museum agree so well

with the description given by Suffrian of P. pectoralis that I must refer them to that

species. It may be distinguished by the closely approached eyes in the male, in con-

nection with the one central and two lateral flavous stripes of the thorax (common to

so many species of the genus); the elytra have very conspicuous bright yellow spots or

spaces placed between the black or dark brown strie—of these spots, four, especially

prominent, are placed transversely below the middle, and a single spot above them and

four below them, transversely placed, as well as the flavous apex, may be distinguished ;

the underside is brown, spotted with pale flavous at the sides of each abdominal segment,

the breast being darker.

Hab. Nortu America, California }.—Mexico, Northern Sonora (Morrison).

The specimens obtained in Sonora by the late Mr. Morrison and named by himself

P. livens agree nearly, but not entirely, with Leconte’s description; and I can only

therefore refer them doubtfully to his species. The Sonoran examples are of a very

pale testaceous colour (in which they agree with the description); the thorax and

elytra are very closely and irregularly punctured, the latter with scarcely any arrange-

ment of the punctures in rows, except at the posterior portion, where traces of strie are

visible (Leconte says that the rows are regular but closer than usual and confused near

the suture); the breast and sometimes part of the abdominal segments are usually

darker (of which Leconte says nothing); and of an occasional testaceous spot on the

‘middle of the thorax (as mentioned in the description) there is no trace in any of the

twelve specimens before me. :

30. Pachybrachys sonorensis.

Black ; above dull flavous; thorax very closely punctured, mottled with dark brown ; elytra closely and irre-

gularly punctured almost throughout, without longitudinal coste, the sides and the disc with some obscure

spots; pygidium black, with two yellow spots ; legs fulvous, spotted with black and white.

Length 14-1? line.

Hab. Mexico, Northern Sonora (Morrison).

Of this, somewhat doubtful, species we have received two specimens, which, owing to

the almost entire absence of elytral coste, I cannot well refer to any yet described.

The head has the usual black vertical and central mark, and is closely punctured ; the

antenne (@ ) extend to about half the length of the body, and are black with the basal

joints fulvous. The thorax is short, nearly three times as broad as long, with rounded

sides and a rather closely punctured disc, the latter having the usual obscure dark lateral

and central bands. The elytra are everywhere impressed with black punctures which

are arranged here and there in ill-defined rows, but the interstices show no trace of

longitudinal coste, either laterally or near the apex; they are of a dull opaque fuscous

colour, interrupted by three obscure flavous spots near the lateral margin, the apex

being of the same colour (if viewed under a lens, the flavous ground-colour is every-

where visible between the punctures). The pygidium is entirely black, closely pubes-

cent, and has two small yellow spots near the apex; the underside is also entirely black,

with a more or less distinct yellow spot on the last segment. The nearest allied species

to P. sonorensis seems to be P. maculicollis; but this latter is of entirely different

152 PHYTOPHAGA.—SUPPLEMENT.

colour, and although the elytra are only furnished with two coste they have the

punctures much more closely placed and forming distinct rows at the sides; the thorax

of P. maculicollis has also well-defined spots. There are but few species from our

region which are devoid of elytral coste, therefore P. sonorensis is rather more easy

to recognize than most of its congeners.

31. Pachybrachys longicollis. (Tab. XXXIX. fig. 12.)

Dark or lighter brown, finely pubescent beneath; thorax proportionately elongate, very closely and finely punc-

tured, with the usual scarcely perceptible darker markings ; elytra irregularly punctured, the sides more

or less distinctly longitudinally costate ; pygidium flavous; legs fulvous, with or without black marks

on the femora.

Length 2 lines.

Hab. Mzxico, Cordova (Sallé).

P. longicollis is well distinguished from the numerous allied forms by its elongate

thorax, the latter being half the length of the elytra in the male and but slightly

shorter in the female. The antenne are scarcely half the length of the body in the

male, and still shorter in the female. The head is finely and closely punctured, pale

brownish, with a dark central line which is widened at its apex. The thorax is very

closely and finely punctured, pale brown, very obscurely spotted with darker brown at

the sides and middle (the usual darker bands to be found in many other species of the

genus being indicated). The scutellum is flavous, margined with dark brown. The

elytra are pale brown, with the interior of the punctures nearly black, the punctures

somewhat differently arranged in the two sexes—in the male they are more widely

separated and form very irregular rows, even on the space near the suture, the outer

portion being, as usual, more regularly punctured and with the interstices slightly

costate; in the female they are very closely placed, very irregularly so on the sutural

space, and the lateral costee are much more distinctly raised; each elytron is also very

obscurely but distinctly marked with two or three dark spots near the sides and two

others near the suture, one below the other. The pygidium is entirely flavous; the

underside and legs in the female are fulvous, and the femora have a dark ring at the

middle which is absent in the male.

82. Pachybrachys brevicollis.

Pale yellowish-white ; the breast and part of the abdomen black; thorax with the sides nearly straight, not

closely punctured, the disc with a pale brown M-shaped mark; elytra with semiregular lines of brown

strie, the sutural two enclosing a wider interstice.

Length 1 line.

Head nearly white, with a narrow brown central stripe which diverges anteriorly into two branches; the

clypeus with a few brown punctures, the rest of the surface impunctate; antenne half the length of the

body, the lower joints fulvous, the rest black; thorax very short, the sides but slightly rounded, the

surface finely punctured on the darker portion, the latter pale yellowish-brown and occupying the usual

position, the lateral spot including a small whitish one; scutellum yellowish-white; elytra with three

double TOWS of brown punctures, the sutural two more separated and enclosing a narrow elongate space,

the portion near the scutellum with some irregularly distributed punctures and bounded by a more regular

short row of punctures within, the interstices at the sides swollen but here and there interrupted by extra

punctures ; underside and legs pale yellowish ; the breast (a spot at the sides excepted), and the middle

of the abdomen, black.

Hab. Guatemaus, Zapote, Duefias (mus. Stuttgart).

The present insect, of which we have received two specimens from the Stuttgart

Museum, very nearly agrees with Suffrian’s description of P. abdominalis (Say), but

differs thus:—The upper surface is not yellowish-grey, but nearly white, the darker

portions and markings of the head and thorax being pale brownish (instead of black);

the thorax, in both specimens, has a M-shaped marking (of which Suffrian says nothing) ;

and the elytral striz enclose strongly raised and shining interstices.

Both examples have the breast black, and they are, no doubt, mature.

33. Pachybrachys nigrofasciatus. (Tab. XXXIX. fig. 13.)

Black 5 legs obseure fulvous ; thorax closely and strongly punctured, with three longitudinal black bands, the

middle one divided anteriorly ; elytra deeply and regularly punctate-striate, the suture and two longitudinal

bands on the disc black.

Length 14 line.

Hab. Mexico, Saltillo in Coahuila (Dr. Palmer).

The presence of two longitudinal black bands on each elytron places P. nigrofasciatus,

of which only a single specimen has been received, in a group containing about six

species, from all of which it seems quite distinct. The head is closely punctured at its

lower portion, fulvous, with the vertex, an elongate spot in the centre (widened at its

middle), and a spot at the base of each antenna black; the antenne extend to a little

beyond the middle of the body, and are black with the lower joints fulvous beneath.

The thorax is not more than twice as broad as long, transversely convex, and strongly

and closely punctured on the black portion, less so on the fulvous interspaces ; the

broad black lateral bands are suddenly narrowed at the apex and extend nearly from

the basal to the apical margin; the central band is widened anteriorly and divided by a

narrow fulvous stripe to its middle. ‘The scutellum is black. The elytra are flavous,

and very regularly punctate-striate; the suture is narrowly black and accompanied by

a row of punctures for its entire length, this row being joined anteriorly to a short

oblique one and followed by a subsutural row which curves outwards from the middle

to the base; the discoidal black band is occupied by three rows of punctures, and is

followed by a narrow costate flavous interspace placed between the next row and

another black band occupying the next three rows of punctures; the flavous lateral

space accompanying the margin is again impressed with a single row of punctures; the

posterior portion of the lateral margin is black, the anterior portion flavous. The

pygidium and the last abdominal segment are flavous, the rest of the underside black ;

the legs fulvous. P. litigiosus, Suffr., differs from P. nigrofasciatus in the sculpture and

Lec., is described as having a diverging central thoracic band; P. othonus (Say) has a

much more transversely-shaped thorax.

34. Pachybrachys decoratus. (Tab. XX XIX. fig. 14.) _

Black ; the thorax closely punctured, the sides, and three spots in front and two at the base, obscure flavous ;

elytra almost regularly punctate-striate, black, two spots at the base, two at the sides, three below the

middle, and one at the apex pale flavous.

Head flavous, the vertex and a central stripe black ; the lower portion of the face strigose-punctate, the upper

portion finely punctured ; antenne extending a little beyond the base of the thorax, flavous, the three or

four terminal joints distinctly thickened and darker ; thorax subcylindrical, transversely convex, the sides

evenly rounded, the surface closely covered with deep and somewhat elongate punctures, the sides, the

anterior margin (the extreme edge excepted), three short stripes in front, and an oblique spot on each

side at the base flavous; scutellum black; elytra convex, with regular rows of punctures, the interstices

flat, except at the sides, where two broader raised spaces are visible, the surface black, with seven pale

flavous spots placed thus :—a round one near the scutellum, an elongate one within the shoulder, followed

by two larger elongate spots placed close together, three shorter ones placed triangularly below the middle,

and a transversely-shaped one at the sutural angle, and in front of this latter spot and close to the lateral

margin is another very narrow short stripe; the pygidium has the sides flavous and the last abdominal

segment is of the same colour ; legs fulvous, the femora with a black spot.

Hab. Mexico, Juquila (Hoge).

Of this well-marked species, differing in the sculpture and elytral pattern from any of

its allies, only a single specimen was obtained. The two bright yellowish-white spots

placed below the shoulder at the sides are the largest and are rather strongly raised ;

the flavous-coloured anterior margin of the thorax is encroached upon by the black

markings on the disc, which in front assume the shape of teeth.

This is a small-sized species, some examples of which are less than one line in length.

I cannot separate our specimens from one contained in the British Museum and named

by Suffrian, whose description, except as regards the colour of the pygidium and under-

side, agrees very nearly with the Central-American insect. In the latter the pygidium

is yellow, with a central black, posteriorly pointed, stripe and narrow similarly-coloured

margins (Suffrian describes it as brown with paler lower margin); the sides of all the

abdominal segments are yellow (the underside of the type is described as black with

the last abdominal segment pale); and the legs are pale brown, with the apex of all

the femora pale yellow. The sculpture of the upper surface agrees entirely with that

of the type, and the above differences are probably due to local variation. The specimens

from Caldera and David are nearly all larger and of more uniform coloration, but agree

in other respects. |

DIASPIS.—CHLAMYS. 155

DIASPSIS (p. 74).

The opinion -expressed by myself that the presence of a second scutellum in this .

genus might be due to the imperfect closing of that part of the elytra is erroneous ;

it is certain, however, that the second scutellum is not always so plainly visible as in

the case of D. paradoxus, and that it is sometimes represented by a very narrow ridge.

Diaspis mestifica (p. 75).

To the Mexican localities given, add :—Acapulco in Guerrero, Huetamo in Michoacan

(Hoge).

The Mexican specimens I refer to this species have two very distinct scutella ; they

are of an obscure dark eneous colour and devoid of the dark velvet-like discoidal mark

mentioned by the author; the elytra have the tubercles nearly all isolated, and they

are distributed as follows—one at the middle of the base, three placed in an oblique

line from the shoulder to the suture, four near the latter towards the apex, and three

or four others near the lateral margin, the interstices being very finely strigose, and

having some deep, remotely placed punctures; the form of the thorax agrees with the

description given by Lacordaire.

Diaspis memnonia (p. 75).

To the Mexican localities given, add:—Northern Sonora (Morrison), Acapulco

(Hoge), Omilteme in Guerrero (H. H. Smith), Juquila (Saldé).

The second scutellum in D. memnonia is very narrow and sometimes only just visible ;

‘there are some true species of Chlamys found in Mexico and Guatemala which almost

exactly resemble the present one, but differ in having red tarsi. The Guatemalan

locality Zapote given for D. memnonia on page 79 is erroneous, and refers to the species

of Chlamys (C. punctipennis) mentioned above. JD. memnonia is a broader and poste-

riorly less narrowed insect than D. mestifica, and has not so many tubercles on the

elytra; the latter have an elevated irregular ridge running from the shoulder nearly to

the suture, and then extending upwards to the base, this ridge surrounding a distinct

blackish space. The specimens from Sonora do not seem to differ from those obtained

at the other localities, and were received from Morrison under the name of Chlamys

polycocca ; they certainly agree very nearly with Lacordaire’s description of that species,

but the double scutellum and the different and more tuberculate structure of the thorax

readily distinguish .C. polycocca from D. memnonia.

CHLAMYS (p. 75).

1 (4). Chlamys godmani. (Tab. XXXIX. fig. 16.)

Head (the vertex excepted), the antenne, legs, and underside ferruginous; above finely pubescent ; thorax.

156 PHYTOPHAGA.—SUPPLEMENT.

greenish-plumbeous, opaque, finely punctured, without elevations; elytra with the basal portion blackish

and finely rugose, the rest bluish and finely punctured and shining.

Length 23 lines.

Of subquadrate, robust, and very convex shape; the head minutely punctured, the vertex with an opaque

greenish spot, the rest ferruginous ; mandibles black ; antenne not extending to the base of the thorax,

dentate from the third joint, entirely fulvous; thorax transversely convex, the convexity even, without

callosities, the basal margin on either side of the median lobe strongly oblique, and thence to the posterior

angles sinuate, the surface dark greenish, velvety in appearance, impressed with minute punctures, and

clothed with very short silvery hairs; elytra very convex towards the middle, the apex of each broadly

rounded, the basal portion finely rugose, rather closely punctured, blackish, and opaque, the posterior

portion metallic bluish or purplish, more remotely punctured, and finely pubescent, a very short trafsverse

ridge (only visible in certain lights) at the middle near the suture; pygidium rugosely punctured, ferru-

ginous, with a large transverse greenish spot ; prosternum gradually narrowed posteriorly.

fab. Panama, Volcan de Chiriqui (Champion).

This species may be distinguished from C. amena by its robust shape and different

punctuation ; the elytra have their posterior portion metallic, and some small, more

shining, metallic spaces along the basal margin. One specimen.

Chlamys pavonina (p. 76).

To the locality given, add :—Mexico, Cordova (Sallé), Jalapa (Hége) ; GUATEMALA

(mus. Stuttgart).

Chlamys cinerea (p. 76).

To the localities given, add:—Mexico, Chilpancingo, Juquila in Guerrero, Jalapa

(Hoge), Teapa in Tabasco (H. H. Smith); British Honpuras, R. Hondo (Blancaneaua).

Lacordaire, in describing this species, says that the head has a subquadrate eneous

spot, and that the antenne are of half the length of the body: in more than twenty

specimens which I have examined the head is entirely fulvous or ferruginous, without

any trace of a spot, and the antenne do not extend beyond the base of the thorax, but

are even much shorter. The examples from British Honduras are almost entirely black

above, but they do not differ in other respects from those from Mexico.

3 (a). Chlamys militaris. (Tab. XX XIX. fig. 17.)

Head fulvous; thorax non-tuberculate, metallic greenish, finely punctured and pubescent, the posterior angles

more or less fulvous; elytra finely punctured and pubescent, with two narrow tubercles near the suture,

fulvous, the sides with a broad longitudinal metallic green band; pygidium, legs, and underside fulvous,

spotted with greenish.

Length 13 line.

Hab. Guatemata, Las Mercedes (mus. Stuttgart).

It is not improbable that this curiously-marked Chlamys is only a variety of C. cinerea ;

the three specimens, however, before me agree with each other and no intermediate

forms have come under my notice. C. militaris is comparatively shorter than C. cinerea,

CHLAMYS., 157

from which it scarcely differs except in coloration. The thorax is fulvous at the sides

behind, or has a small fulvous spot at the middle of the basal margin; the elytra may

be described as metallic greenish, with the suture and the apex fulvous, this colour |

extended on either side of the suture towards the base and occupying the inner half of

the basal margin.

Chlamys episcopalis (p. 77).

To the Mexican localities given, add :—Jalapa, Iguala in Guerrero (Hoge).

Chlamys maculipes (p. 78). —

To the localities given, add :—Mexico, Cosamaloapam, Playa Vicente (Salle), Acapulco

and Chilpancingo in Guerrero, Matamoros Izucar in Puebla (Hoge, H. H. Smith), Atoyac

in Vera Cruz, Teapa in Tabasco (H. H. Smith); Guatemaza, Llano grande (mus. Stutt-

gart), San Gerénimo (Champion).

8 (4). Chlamys maculifrons.

Obscure dark greenish, opaque, pubescent ; the head, the base of the antennzx, a short central stripe in front of

the thorax, the sides of the pygidium and of the abdomen, and the legs in great part, ferruginous; elytra

with four or five short tubercles, four discoidal and one subsutural near the apex.

Length 13-2 lines.

Hab. Mexico, Ventanas in Durango, Tapachula in Chiapas (Hoge); GuaTEMALa,

Zapote (Champion).

Closely allied to C. maculipes, but differing in the much longer and more slender

antenne and in the shape and colour of the thorax. ‘The thorax (if looked at sideways)

is depressed anteriorly, and is not so convex and evenly rounded as in the allied species ;

the two small bare spots at the sides, very distinct in C. macudipes, are absent, and a

narrow ferruginous longitudinal stripe extends from the centre of the anterior margin

to about the middle, the anterior margin itself being narrowly ferruginous. ‘The elytra

are of a very dull opaque greenish-black, rather remotely punctured, and clothed with

extremely short pubescence (this being more scattered than in C. maculipes); the

tubercles are very similar to those of C. maculipes. About a dozen specimens were

obtained, all but one being from Mexico.

8 (s). Chlamys semilutea. (Tab. XXXIX. fig. 15.)

Below ferruginous, above obscure dark olive-green ; thorax finely punctured, its sides ferruginous, the elevation

with a lateral ridge; elytra distinctly punctured, opaque, with longitudinal and short transverse ridges.

Length 13 line.

Head bright ferruginous, indistinctly punctured, the vertex with a small elongate obscure blackish spot which

is divided at its apex; antennz with the fourth and following joints transverse, fuscous, the lower four

joints fulvous; thorax minutely and closely punctured, the disc gradually raised into a strong elevation

(this being nearly perpendicular behind and furnished above with an acute oblique ridge which runs halfway

158 PHYTOPHAGA.—SUPPLEMENT.

down the elevation), the sides ferruginous (but the edge of the darker portion strongly dentate near the

base, so that the two colours are not divided by a straight line) ; elytra very slightly narrowed posteriorly,

rather flattened, of a very opaque dark greenish colour, more strongly punctured than the thorax, with

the following prominences—an elongate tubercle near the suture before the middle, another, but shorter,

one at the middle of the base, two rows of tubercles, placed one below the other and extending obliquely

downwards from the shoulder to the middle of the suture, a strongly raised conical tubercle close to the

suture near the apex, and a smaller tubercle at the sides ; pygidium ferruginous, with two dark greenish

spots near the apex ; legs ferruginous, the tibie with the apex more or less black or greenish.

Hab. Panama, Volcan de Chiriqui (Champion).

C. semilutea is well distinguished by its peculiar coloration, and cannot be mistaken

for C. maculipes or its allies, owing to the absence of pubescence from the upper surface

and the presence of rather numerous tubercles on the elytra; it seems somewhat allied

to the Brazilian C. corrugata, Lac. Two specimens. .

Chlamys insularis (p. 78). (Tab. XX XIX. fig. 19, var.)

To the localities given, add:—Panama, Bugaba, Volcan de Chiriqui, David, Caldera

(Champion).

We now figure a Chiriqui specimen of one of the varieties of C. insularis, in which

the thoracic and elytral tubercles are more strongly prominent than in the type. The

general colour of the upper surface is either black with more or less fulvous tubercles,

fulvous with the tubercles black, or entirely brownish-eneous; the amount of the

fulvous colour of the thorax also varies; the legs are more or less spotted with fulvous.

Chlamys frontalis (p. 79). (Tab. V. fig. 12 a.)

The reference to the Plate was accidentally omitted on page 79.

11 (a). Chlamys fulvomaculata. (Tab. XL. fig. 1.)

Subquadrate, narrowed posteriorly, black ; the head, thorax, abdomen, and legs spotted with fulvous; thoracic

elevation divided, each division trituberculate ; elytra metallic bluish, eneous, or black, strongly tuber-

culate at the base and apex, the disc with a high oblique ridge; pygidium carinate, nearly smooth,

Length 13-13 line.

Evidently very variable in colour and also to some extent in sculpture; head black spotted with fulvous, or

entirely fulvous, rather sparingly punctured ; antenne fulvous, the apical joints darker; thorax with a

moderate elevation, the latter divided into two portions each of which is furnished with three tubercles

placed triangularly, the lateral portion finely punctured and with one or two very obscure tubercles, the

anterior portion almost entirely fulvous or only spotted with that colour; elytra with a large tubercle at

the middle of the base and two others near the apex, and an oblique more or less interrupted ridge ex-

tending from the shoulder towards the suture, where it forms a strongly raised transverse ridge; pygidium

sparingly punctured, rather smooth, with a longitudinal central ridge ; legs fulvous, more or less spotted with

fuscous; abdomen with some fulvous spots.

Hab. Mexico, Cordova (Sallé); GuaTEMALA, near the city (mus. Stuttgart).

In the single example from Mexico the thorax shows at the apex of each division of

the elevation an oblique ridge, in front and also at the side of which a small round

CHLAMYS. 159

tubercle is placed; in the Guatemalan specimens this ridge is scarcely perceptible and

of a more tuberculate shape, three tubercles being visible when the thorax is looked at

in a certain way. One of the Guatemalan specimens has the elytra of an obscure

purplish colour; in the other they are slightly eneous and the tubercles partly fulvous.

C. fulvomaculata is allied to C. frontalis, but is more narrowed posteriorly and also

differs in the form of the thorax; the latter in C. fulvomaculata is sparingly punctured

and has no reticulations, while in C. frontalis it is very closely punctured and finely

rugose, and has two short oblique ridges behind only.

11 (8). Chlamys collaris. (Tab. XXXIX. fig. 20.)

Subcylindrical, black, opaque ; the head, antennz, a small spot near the anterior margin of the thorax, and the

four anterior legs fulvous; thorax finely punctured and reticulate, with a rounded elevation; elytra with

longitudinal and transverse ridges, the interstices foveolate and reticulate.

Var. The thorax with the anterior portion and some small spots flavous.

Length 14 line.

Head closely and finely punctured, fulvous, a2 small elongate spot at the middle of the vertex, and two smaller

spots above the base of the antenne black; antennz fulvous, the last four joints fuscous, the fourth and

following joints transverse ; thorax with a strongly raised but evenly rounded central elevation, the middle

of which is distinctly but not deeply channelled, the sides of this channel bounded by a ridge, the surface

closely and finely punctured at the sides, the elevation itself reticulate, the anterior angles, and a small

more or less distinct spot placed at the middle near the anterior margin, fulvous; scutellum impunctate ;

elytra parallel, subcylindrical, black, without isolated tubercles but with the following longitudinal ridges

—one running obliquely from the middle of the base to the apex and gradually approaching the suture,

another commencing between the shoulder and the first ridge, and a third close to the lateral margin

behind,—these ridges connected by transverse or oblique shorter ones (an oblique ridge near the base

between the first longitudinal one and the suture, a more strongly raised and transverse ridge immediately

below the middle, often connected along the suture with the first oblique ridge, and two other transverse

ridges at the sides, one at, the other below, the middle), all the spaces between the ridges closely punc-

tured but not reticulate, the suture dentate throughout; pygidium closely punctate, and with a long

central, and two shorter lateral, ridges ; the underside foveolate-punctate; the four anterior legs fulvous,

the posterior femora and tibie partly black, but varying in this respect.

Hab. Mexico, Acapulco in Guerrero (Hoge).

C. collaris, although not differing to any great extent in its general system of sculp-

turing from many of its Brazilian congeners, may be known by the thorax being spotted

(the anterior spot being present in all the specimens), closely punctured, and without

tubercles; the elytra without isolated tubercles, but with longitudinal, oblique, and

transverse ridges (which are seen to better advantage if the insect is viewed from in

front).

11 (c). Chlamys hogei. (Tab. XXXIX. fig. 18.)

Black, shining, the antenne (the apical joints excepted), labrum, palpi, and tarsi flavous; head and thorax

closely punctured, the latter with an evenly rounded, scarcely channelled, elevation ; elytra with two

distinct subsutural costs, these connected with a short transverse ridge at the middle and with another at

the sides, the interstices very uneven and remotely punctured.

Var, The head and the anterior margin of the thorax flavous.

Length 13 line.

160 PHYTOPHAGA.—SUPPLEMENT.

Head flat, closely punctured, with a small and very obscure fulvous central spot; antenne flavous, the apical

four joints fuscous ; thorax black and shining, the middle portion raised into a rounded and moderately

high elevation which is bounded at the sides and posteriorly by a distinct groove, the surface of the

elevation reticulate throughout and remotely punctured, and with the centre traversed by an obsolete

channel which is bounded laterally by a very short ridge, the sides also raised into an obsolete tubercle ;

elytra very slightly narrowed posteriorly, each with a longitudinal costa commencing near the scutellum

and extending to the middle, and here joined by a transverse ridge to the second costa, the latter com-

mencing at the middle of the base and extending nearly to the apex (the middle portion appearing to be

double owing to another closely approached ridge running parallel with it), and a short third ridge running

from the middle of the second to the shoulder (its lower portion bounded by a transverse ridge which

turns downwards near the lateral margin and below the middle joins another transverse one so as to

include a subquadrate excavated space), the apical portion entirely occupied by fovew and short tubercles,

the interstices remotely punctured, the suture dentate throughout its entire length; pygidium finely

punctured, with an obsolete central ridge ; legs black, with the upper margin of the anterior and inter-

mediate femora more or less fulvous, the tarsi flavous.

Hab. Mexico, Acapulco in Guerrero (Hé6ge).

C. héget is very closely allied to and possibly only a variety of C. collaris, but differs

from it in the sculpture of the thorax :—in C. collaris the thorax is very closely punc-

tured at the sides and the interspaces are almost as closely wrinkled, the wrinkles

forming reticulations at the top of the elevation ; in C. héget the sides of the thorax

are comparatively remotely punctured, and the interstices are smooth and shining and

the reticulations few.

11 (vp). Chlamys inconspicua.

Elongate, subcylindrical, black, opaque ; the labrum, antenne, and tarsi fulvous; thorax finely punctured, the

central elevation channelled in the middle; elytra with obsolete short longitudinal ridges, partly connected,

the suture smooth.

Length 3~1 line.

Head finely rugose and reticulate ; labrum fulvous ; antenne with the fourth and following joints transverse,

fulvous, the terminal joints obscure fuscous; thorax with the centre raised into a rounded hump, which is

channelled in the middle and has its sides near the top reticulate and divided by some ridges, the lateral

portion very finely punctured, the interstices nearly smooth ; elytra entirely opaque, finely granulate and

punctured, the longitudinal ridges partly indistinct (one placed close to the suture, another running from

the middle of the base to the apical portion, and a third starting from the shoulder and extending almost

as far posteriorly as the second) and with short transverse ridges between them, the interspaces uneven

and finely punctured, the suture entirely smooth; pygidium rugose and with three more or less distinct

longitudinal ridges ; underside and legs black and opaque, the tarsi bright fulvous.

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

This opaque, dull black Chlamys may be known at once from the allied forms by

the elytral suture being smooth (or without teeth), which character it has in common

with several species found in Brazil. There is no characteristic design in the elytral

sculpture, and the arrangement of the ridges is less distinct than in many of the allied

species: in some specimens a short transverse ridge placed at the middle close to the

suture and two subtubercular longitudinal elevations at the apex (one near the suture,

the other at the sides) are plainly visible. Two diverging rather distinct ridges, one

on either side of the median channel, are placed at the top of the thoracic elevation.

CHLAMYS. é 161

Chlamys celocephala (p. 80).

To the Mexican locality given, add :—Jalapa (Hoge), Cordova (Sallé).

The two specimens obtained at the above localities agree with Lacordaire’s description

as regards the excavated head, the carinate epistome, and the sculpture of the pygidium,

but differ from it in size and colour: the length, instead of two and a quarter, is barely

two lines, and the colour (with the exception of that of the head, antenne, part of the

thorax, and the legs) is nearly black. Similar differences are, however, frequently to

_ be found in species of this genus. The present insect differs distinctly from the allied

forms in the sculpture of the head; the upper surface is nearly black but with a slight

bronze tint, the thorax having fulvous spots at the sides and also near the anterior

margin.

14 (4). Chlamys instabilis. (Tab. XL. fig. 2.)

/Eneous or black, the labrum, antenne, and tarsi fulvous; thorax finely strigose, its elevation deeply divided,

the sides with one or two tubercles; elytra with a sinuate strongly raised oblique ridge extending from

the shoulder to the apex, the apical portion with five isolated tubercles, the interstices deeply punctured.

Length 14-14 line.

Head with some irregularly placed punctures, and with a groove in the middle; thorax finely strigose and

remotely punctured, the elevation divided by a broad channel (the part on either side of it distinctly ridged

posteriorly) and laterally furnished with a rounded tubercle preceded by a short ridge, the sides with a

distinct tubercle, the surface finely strigose throughout; elytra minutely granulate, with a very strongly

raised ridge, formed by three semicircular protuberances, extending from the shoulder to the suture, the

posterior portion with five distinct isolated tubercles, of which the two placed nearest the suture are the

' largest, the interspaces rather deeply punctured.

Hab. Mexico, Tepetlapa in Guerrero, Cuernavaca in Morelos, Orizaba, Atoyac in

Vera Cruz, Teapa in Tabasco (H. H. Smith); Guaremaa, Las Mercedes (Champion) ;

PanaMA, Bugaba, David in Chiriqui (Champion).

C. instabilis is perhaps best placed near C. assimilis, Lac.; it is also, no doubt, closely

allied to several Brazilian species described by Lacordaire, but seems to differ from all

these either in the sculpture of the thorax or in the fulvous tarsi. The general colour

varies from bronze to black. If the insect is looked at from above, three distinct

transversely-placed tubercles are to be seen at the apex of each elytron, the outermost

one being the smallest; in most of the allied species there are only two tubercles visible

and these protrude, apparently, beyond the apex.

A specimen from Cuernavaca is figured.

14 (s). Chlamys sublevicollis. (Tab. XL. fig. 3.)

Subquadrate, parallel, black, the antennae, labrum, and tarsi fulvous; thorax with a rounded elevation, the

latter channelled and bicarinate, the sides nearly smooth ; elytra with strongly raised longitudinal costz

and two tubercles, the latter placed near the apex.

Length 13 line.

Hab. Mexico, Matamoros Izucar in Puebla (Hége). A single specimen.

BIOL. CENTR.-AMER., Coleopt., Vol. VI. Pt. 1, Suppl., November 1889. y

162 PHYTOPHAGA.—SUPPLEMENT.

C. sublevicollis is of a deep black general colour with a slight silky gloss. The head

is finely punctured and has some small fulvous spots placed at the sides, at the middle,

and within the ocular indentation ; the labrum and the antenne are entirely fulvous.

The thorax at the sides has only a few fine punctures and an obscure tubercle ; the

raised central portion is rounded and distinctly channelled at the top, bounded laterally

by a very distinct ridge, and with the sides rather strongly reticulate but scarcely

punctured. The elytra are sparingly punctured and have two strongly raised coste

extending from the base to the middle, the coste being here joined and continued as a

single ridge nearly to the apex and ending in a strongly raised tubercle; a third costa

is placed close to the second one and extends from the middle to some distance from

the apex, where it ends; the sides below the shoulders are furnished with a U-shaped

ridge, which is again connected by a straight costa with a similar curved ridge near the

apex, the latter being reversed in shape and joined to an elongate tubercle near the

lateral margin. The pygidium has a central carina and is excavated in several places

at the sides. The deep black and silky surface, the nearly smooth sides of the thorax,

and the strongly raised elytral coste will assist in the recognition of C. sublevicolits.

14 (c). Chlamys scabrosa. (Tab. XL. fig. 4.)

Subelongate, parallel, obscure dark seneous, the labrum, the basal joints of the antennz, and the tarsi flavous ;

thorax with the central elevation divided, the elevation reticulate above; elytra with indistinct longitudinal

and more distinct transverse ridges, the apex with two conical tubercles.

Length 13-12 line.

Of rather elongate shape, very obscure dark cupreous or eneous, with a slight reddish tint ; head closely rugose,

the rough portion divided by a narrow transverse smooth space ; antennz with the second and third joints

very small, the fourth and following ones strongly transverse, the lower six joints fulvous, the rest fuscous ;

thorax with a moderately raised central elevation which is divided into two parts at the top, each of these

parts being blunt, divided again, and foveolate, and velvety-black in appearance (when seen in certain

lights), the sides finely punctured, extremely minutely granulate, and with an obsolete tubercle placed at

the base of the elevation on either side; scutellum strongly transverse, ending laterally in a rather distinct

point; elytra minutely granulate, with three or four very indistinct longitudinal ridges, of which the first

two near the suture are connected before and immediately below the middle by a transverse ridge (these

transverse ridges extending nearly across the disc to the lateral margin), and a strongly raised conical

tubercle at the suture near the apex and two less distinct tubercles nearer the sides, the interspaces more

or less excavated and finely punctured; pygidium closely punctured, and excavated at the base and at the

sides.

Hab. Mexico, Chilpancingo in Guerrero, Zacualtipan in Hidalgo (Hoge).

I cannot with certainty refer this insect to any species described by Lacordaire ; it is,

no doubt, closely allied to C’. melancholica, C. affinis, &c. C. scabrosa, if looked at with

the naked eye, is dull and nearly black—with a lens, its reddish or brownish-zneous

colour becomes at once apparent; the longitudinal ridges of the elytra can only be

distinguished when the insect is held in certain positions, and well-defined tubercles,

except the one near the apex, are absent.

CHLAMYS. 163

14 (p). Chlamys punctipennis. (Tab. XX XIX. fig. 22.)

Subquadrate, narrowed posteriorly, obscure zneous, the labrum, antennx, and tarsi fulvous; thorax minutely

granulate, the elevation channelled and with a tubercle on each side; elytra with a strong oblique ridge

before the middle, the space between this and the base closely punctured, the posterior portion with four

or five tubercles.

Length 14 line.

Hab. Mexico, Jalapa (Hoge), Cordova (Sallé); Guatemata, Zapote (Champion) ;

PanaMA, near the city (Champion).

In colour and in sculpture this species resembles Diaspis mestifica, from which the

single scutellum and the red tarsi at once distinguish it; the last-mentioned character

and the different sculpture of the elytra will separate it from C. assimilis and C. plicata,

Lac. The thorax has the surface minutely granulate throughout and remotely punc-

tured, and has a rounded tubercle on each side; the elevation is, as usual, divided at

the top, each part having a rather obsolete ridge running down sideways, and another

_ obsolete and shorter ridge may be seen near the anterior portion. The elytra have the

space between the oblique ridge and the base closely punctured and semireticulate, and

of a darker appearance in certain lights than the rest of the surface; the oblique ridge

is strongly raised (as in some of the allied species) and near the suture forms an arcuate

transverse tubercle ; immediately behind this another transverse, less acutely raised ridge

is placed, and an elongate elevated tubercle is situated close to the suture near the apex.

C. punctipennis may be known by the posteriorly narrowed shape, the closely punctured

anterior portion of the elytra, and the red tarsi; C. tragulus, Lac., differs in the colour

of the underside and in other particulars.

Our figure is taken from a specimen from Cordova.

Chlamys decipiens (p. 80).

To the locality Mexico, add:—Chilpancingo in Guerrero (H. H. Smith), Cordova

(Hoge).

Two specimens from the above localities agree very well with Lacordaire’s description.

C. decipiens is of a very obscure eneous colour, and may be known from other similarly-

coloured species by the sides of the pygidium and of the abdomen being fulvous; the

thoracic elevation is divided at the top into two parts, each of which has a distinct

ridge running to the base.

Hab. Norra America 1.—Mextco, Cordova (Hoge).

164 PHYTOPHAGA.—SUPPLEMENT.

The single specimen obtained by Herr Hége in Mexico does not seem to differ from

others from North America contained in my own collection. The thorax has the raised

middle portion divided into two rather pointed parts, but this division is placed at a

very short distance from the base (in many species of Chlamys the separated portion is

placed more towards the middle), and almost the entire surface is finely strigose. The

Mexican specimen is nearly black, but with the head of a brownish-zneous colour and

the antenne entirely fulvous.

17 (s). Chlamys strigicollis. (Tab. XXXIX. fig. 21.)

Subquadrate, black, the head, antenne, and legs (part of the femora excepted) fulvous; thorax with a nearly

perpendicular high elevation, obliquely strigose throughout ; elytra with four very strongly raised longi-

tudinal ridges near the base, and two shorter, still more elevated elongate tubercles near the apex.

Length 13-14 line.

Head scarcely visibly punctured, fulvous, the vertex sometimes with a small black spot; antenne short, dentate

from the fifth joint, entirely fulvous; thorax with a strongly raised perpendicular hump, the top of which

is deeply channelled but rounded, its sides and the rest of the surface traversed by oblique strige which

are shining and partly united, the interspaces here and there impressed with a few punctures ; scutellum

impunctate, transverse ; elytra nearly subquadrate, black, with three very distinct ridges commencing at

the base and united at the middle by an equally distinct transverse ridge which extends obliquely towards the

shoulder, and behind the transverse ridge a longitudinal one running parallel with the suture and another

with the lateral margin, both with acute edges, the interspaces deeply punctured and minutely strigose ;

pygidium with three longitudinal ridges; legs fulvous, the outer sides of the four posterior femora more

or less black.

Hab. Panama, Bugaba (Champion).

C. strigicollis seems to be allied to C. chrysocephala, Klug, by its coloration and other

characters; but differs in the shape and size of the thoracic elevation, and in having the

entire surface of this part covered with strige; the elytral elevations or ridges are also

more than usually raised, the most prominent one being placed near the lateral margin

at the apex.

17 (c). Chlamys scrobicollis.

Chiriqui specimens agree well with Lacordaire’s description of this insect. C. scrobi-

collis is a small-sized species (3-1 line), of shining black colour, and may be known by

the three more or less distinct sinuate ridges on each side of the thoracic elevation; the

elytral costa, which extends from the shoulder to the middle of the suture, is very

strongly raised, and some prominent tubercles are placed near the apex ; the labrum,

antenne, palpi, and tarsi are fulvous or flavous.

20 (a). Chlamys brunnea.

elytra impressed with brown punctures, and each with four longitudinal coste, the first two joined below

the middle.

Length 14-2 lines.

Head with a shallow depression between the eyes, impressed with a few dark brown punctures; antenne

fulvous, the apical four joints fuscous; thorax of a yellowish-brown colour, rather closely impressed with

brown punctures at the sides, the middle portion raised into a rounded comparatively slight elevation

which is limited posteriorly by a constriction or groove, the elevation channelled in the middle and

bounded on each side by a distinct ridge which extends nearly to the anterior margin (this ridge much

interrupted at the top and sending off three or four transverse branches which run down each side of the

elevated portion); elytra subquadrate, opaque, of the same colour as the thorax, with numerous larger

dark punctures, four longitudinal coste—the first commencing near the scutellum and extending to the

middle near the suture and joined by a short oblique branch to the second costa immediately below the

middle, the latter extending upwards to the middle of the base and downwards to a little distance from

the apex, where it turns outwards, the third costa placed near the shoulder and joining the second before

the middle (but indistinctly continued posteriorly), the fourth very indistinct, shorter than the third, and

running from the shoulder obliquely downwards,—a single short tubercular ridge near the suture below

the middle, a similar ridge marking the apex of the second costa before it turns outwards, and at the

apical and lateral portions some more or less distinct transverse coste, the suture dentate throughout ;

pygidium deeply punctured, and furnished with some short ridges ; underside closely foveolate-punctate.

Hab. Panama, Volcan de Chiriqui (Champion).

The absence of isolated pointed tubercles from the elytra and the differently sculptured

thorax separate C. brunnea from C. luteola. The uniformly-coloured upper surface and

the feebly raised disc of the thorax distinguish the species from most of its allies.

20 (p). Chlamys insignis. (Tab. XXXIX. fig. 25.)

Subquadrate, robust, entirely pale ochreous; thorax finely punctured, the base conically raised and the apex

of the raised part impressed with a fovea; elytra with about ten isolated tubercles, the interspaces remotely

impressed with brown punctures.

Length 13-2 lines.

Head finely punctured, the punctures irregularly distributed ; antenne fulvous, the fourth and following joints

broadly widened ; thorax finely punctured throughout, the posterior portion gradually raised into a conical

protuberance, which is slightly foveate at the apex only, the surface of an opaque pale ochreous or

fulvous colour with indications (in some specimens) of spots at the sides and darker markings ; scutellum

flavous or ochreous; elytra nearly subquadrate, of the same colour as the thorax, each with ten or twelve

isolated rounded tubercles placed thus—four nearly parallel with the suture (the second placed close to it),

four others, forming a second row, three placed triangularly near the apex, and one or two (nearly obsolete)

anteriorly at the sides,—the interstices remotely impressed with small piceous punctures and the extreme

basal margin also of that colour, the suture dentate throughout; pygidium, underside, and legs entirely

flavous.

Hab. Panama, David, Caldera in Chiriqui, Tolé (Champion).

This species is perhaps nearest allied to C. luteola, from which the unicolorous upper

surface, the undivided thoracic elevation, which only at its apex has a shallow groove,

and the isolated rounded tubercles of the elytra distinguish it; the elytra have the

usual oblique lateral constriction.

20 (c). Chlamys prodigiosa. (Tab. XL. fig. 5.)

Subquadrate, flavous, spotted with black; thorax with two crests, each divided at the top; elytra with five or

166 PHYTOPHAGA.—SUPPLEMENT.

six strongly raised and some smaller black or metallic purplish isolated tubercles; breast and legs spotted

with black.

Length 2 lines.

Head flavous, with a few dark punctures and a black spot on the vertex, and a smaller spot above each eye;

antenne fulvous; thorax with two acutely-raised crests or ridges which are separated by a deep channel,

each crest being divided at its apex into three prominences or tubercles, the disc flavous, the sides, the base,

and the space between the two principal ridges spotted with black; scutellum flavous, its base black ;

elytra with deep punctures, strongly raised isolated tubercles (one at the middle of the basal margin, two

smaller ones placed obliquely between the shoulder and the suture, three in the same direction below the

middle, and two large ones of trigonate shape near the apex), and a short transverse prominent ridge near

the suture at the middle, the tubercles of a shining black colour, the two apical ones purplish-blue ;

pygidium flavous, with a large black spot near the apex; the underside flavous, spotted with black ;

abdomen with a small tubercle on either side, the tubercle marked with black; legs flavous, the femora

with a large central black patch.

Hab. Guatemata (coll. Jacoby).

Allied to the Brazilian C. schotti, Koll., but differing in the sculpture of the thorax

and of the elytra, and in: the tubercles of the latter being partly metallic in colour.

We have received a single specimen of this interesting new species from the Stuttgart

Museum.

20 (p). Chlamys nitidiceps. (Tab. XI. fig. 6.)

Narrowly elongate, obscure reddish-cupreous, the base of the antenne, the labrum, and the tarsi flavous; thorax

irregularly tubervulate, its elevation channelled; elytra deeply punctured, the apex with some blunt

tubercles, the disc with obscure longitudinal ridges.

Length 1 line.

Head flattened, finely reticulate-rugose ; labrum fulvous; antenng with the basal joint flavous, the other joints

obscure fuscous ; thorax with the middle portion moderately raised, the elevation bounded posteriorly and ~

at the sides by a deep sulcation and divided in the middle by a shallow channel—each division forming a

blunt longitudinal ridge at the apex and indistinctly divided into two blunt tubercles, the anterior portion

with a short transverse ridge placed in front of the longitudinal one,—the entire surface irregularly reti-

culate; elytra closely and deeply punctured, with a broad longitudinal ridge down the middle—the surface

of the ridge impressed with two rows of punctures and the ridge itself ending near the apex in a blunt

tubercle,—three blunt tubercles near the apex, an indistinct costa running close to the suture from the

base to the middle, where it joins the broad ridge by a transversely-shaped tubercle, a blunt tubercle at

the middle of the base, and a short transverse ridge at the sides near the middle, the suture denticulate

throughout ; pygidium with three distinct longitudinal coste, the spaces between the coste hollowed ; the

femora dark fuscous, the tibia cupreous in tint.

Hab. Guatemaua, Cerro Zunil (Champion). A single specimen.

The uniform obscure reddish-cupreous colour, the elongate shape, and the tricarinate

pygidium distinguish this small species from its allies, C. schuchtt, Koll., from Brazil, &c.

It also differs from C. schuchti in the sculpture of the thorax and in the colour of the

legs. In C. nitidiceps the tibie are distinctly cupreous.

Chlamys stictica (p. 83).

To the Mexican locality given, add:—Cuernavaca, Jalapa (Hoge), Atoyac in Vera

Cruz, Cordova (Sallé), Teapa in Tabasco (H. H. Smith).

CHLAMYS. 167

Specimens from the above localities agree fairly well with Lacordaire’s description of

C. stictica; they vary a good deal ‘iin colour, the thorax being pale and almost un-

spotted in some examples, and in others covered with black spots which occasionally

form two lateral bands and a short central stripe at the base; nearly all have a pale

bright flavous or ferruginous stripe on the disc of the thorax. The middle portion of

the thorax is raised into a round moderate elevation, which is not channelled but has

generally a small oblong depression at the top: this is evidently the principal character

by which C. stictica may be known. It is somewhat doubtful whether the Guatemalan

specimens belong to the same species, as they have the elytra constricted at the middle

and are also more elongate ; they agree, however, in the main points with the Mexican

insect.

25 (a). Chlamys bugabensis. (Tab. XX XIX. fig. 24.)

Pale flavous ; thorax with four tubercles, the disc with a transverse dark band; elytra closely punctured, with

a subsutural ridge on the disc extending from the middle to the apex and five tubercles, a transverse band

at the base and the tubercles greenish.

Length 2 lines.

Head flat, with a few fine punctures, pale flavous; antenne flavous; thorax finely granulate and punctured,

the posterior portion raised into a rounded feeble elevation, the top of the elevation being broadly but

shallowly channelled and furnished with four small tubercles, the disc with a transverse strongly sinuate

dark greenish band which does not extend to either margin ; scutellum black, impunctate; elytra sub-

quadrate, constricted at the sides, closely punctured in longitudinal rows, with a distinct ridge running

obliquely from the middle of the base towards the suture near the apex, where it is more strongly raised,

and numerous tubercles—two near the basal margin, one near the suture before the middle, a transverse

one at the middle, and two others at the sides below the middle,—the tubercles, a spot on the shoulder,

and a transverse band at the base, not extending to the middle, dark olive-green ; the elytral epipleurse

at the base and some small spots at the sides of the breast dark olive-green, the rest of the underside and

the legs bright flavous.

Hab. Panama, Bugaba (Champion).

The coloration and sculpture of this species distinguish it readily enough from the

allied forms. ‘The elytra, in addition to the more prominent subsutural costa, have two

other coste (only visible in certain lights), one placed near the shoulder and one

towards the apex near the lateral margin.

25 (s). Chlamys semifulva. (Tab. XL. fig. 7.)

Head and thorax fulvous; the latter with two more or less distinct brown bands, its elevation subglobose ;

elytra with longitudinal and transverse ridges, brownish-fuscous, with a narrow fulvous transverse band

near the apex; legs and abdomen fulvous.

Length 1 line.

Head entirely fulvous, rugose; antenne fulyous; thorax finely rugose-punctate, the elevation finely reticulate,

subglobose, and with a narrow channel on the top bounded on either side by a fine raised ridge, the

surface bright fulvous, the elevation with two dark brown stripes behind and a small spot on either side

laterally ; scutellum stained with fulvous; elytra subquadrate, slightly narrowed posteriorly, dark fuscous,

with a narrow fulvous or flavous transverse band near the apex, four very distinctly raised sinuate

longitudinal ridges—the first subsutural, S-shaped, and joined below the middle to the second ridge, the

latter extending upwards to the middle of the base and downwards to near the apex, where it turns

168 PHYTOPHAGA.—SUPPLEMENT.

outwards, the third ridge commencing near the shoulder and joined before the middle by a transverse

costa to the second ridge, the fourth commencing at the shoulder and connected by @ transverse costa (in

a line with the first transverse ridge) with the third ridge,—and several small tubercles near the apex,

the interstices simply punctate; pygidium fulvous, spotted with black at the base, its surface finely

rugose ; below fulvous, the breast dark fuscous ; the posterior femora more or less fuscous.

Hab. Mexico, Jalapa (Hoge), Puebla (Salié).

Much smaller than C. stictica or C. pectoralis, and differing from these in the colour

of the elytra (which is, however, probably subject to variation) and of the underside.

Two specimens.

27 (a). Chlamys pectoralis.

Obscure fulvous, the middle of the breast and of the abdomen black ; thorax with a regular rounded elevation ;

elytra with excavated longitudinal spaces bounded by raised cost, and without isolated tubercles ;

pygidium longitudinally carinate in the middle, spotted with black.

Length 14 line.

Nearly cylindrical in shape; head finely punctured and granulate, fulvous, with a small black spot on the

vertex ; antenne entirely fulvous ; thorax twice as broad as long, fulvous, the middle portion raised into

a regularly rounded elevation which is bounded posteriorly and laterally by a distinct sulcation, the sides

covered with shallow non-confluent fovew, the elevation shallowly grooved in the middle, reticulate, and

with a small black spot at the top; elytra slightly constricted at the middle, fulvous, opaque, with the

excavated spaces and raised coste placed thus—a longitudinal sulcation near the suture, the sulcation

limited by two strongly raised costs at the sides and by a transverse ridge at the middle, and followed

below the latter by a smaller similarly enclosed sulcation (the first of these coste continued towards the

apex, where it forms an elongate tubercle and then curves towards the sides where it is connected with

other coste), an excavation at the middle near the sides, bounded laterally by a short longitudinal ridge

(which forms the continuation of a longer one commencing at the shoulders) and inwardly by a strongly

raised ridge (these connected by a short transverse elevation), and a strongly raised elongate tubercle

near the apex (in a line with the subsutural one),—the interstices between the numerous ridges closely

foveolate-punctate, the suture dentate throughout ; pygidium reticulate and punctured, carinate in the

centre, its base spotted with black; underside closely reticulate-punctate, fulvous, the breast and middle

portion of the abdominal segments, as well as the coxal cavities, black ; legs fulvous, with a more or less

distinct black spot on the middle of the posterior femora.

Hab. Mexico, La Parada, Juquila (Sallé).

C. pectoralis closely resembles the specimens which I have referred to C. gysseleni ;

but the thorax in the present insect is much more narrowed in front, and its elevation

is bounded by a distinct sulcation at the sides and base; the elytra are more deeply

excavated and have the coste more strongly raised ; the antenne are entirely fulvous;

and the breast and the abdomen are partly black. C. stictica may be known from

C. pectoralis by the less deeply excavated elytra and less strongly raised coste.

Chlamys insidiosa (p. 85). (Tab. XL. fig. 8.)

To the locality given, add:—Mexico, Ventanas in Durango (Hége); Guaremata, San

Gerénimo (Champion).

Two specimens from the above localities agree exactly with Lacordaire’s description.

We figure the one from Ventanas.

Chlamys venusta (p. 88).

Chlamys fasciaticollis, Jac. huj. op. p. 85.

To the Mexican localities given, add :—Jalapa (Hége).

An examination of the additional material now at my disposal proves that C. fascia-

ticollis (Tab. V. fig. 7) cannot be separated from C. venusta.

43. Chlamys admirabilis. (Tab. XX XIX. fig. 23.)

Subquadrate, black, the head, the sides and front of the thorax, the pygidium, and the sides of the abdomen

flayous ; thorax with a very strongly raised perpendicular elevation, the elevation divided at the top, the

sides impunctate; elytra with a very acute ridge at the middle, a tubercle at the base, and three tubercles

near the apex, the central ridge fulvous within.

Length 23 lines.

Head finely punctured, flavous, the vertex darker and finely rugose; antenne fulvous, the apical seven joints

broadly dilated ; thorax with its middle portion suddenly and perpendicularly raised, the elevation deeply

divided at the top, and each part furnished with a ridge on its inner side and some deep punctures at the

apex, the central portion deep black, this colour extending in two lines down the middle to the anterior

margin, the base with two elongate fulvous spots placed in front of the scutellum, the sides broadly

flavous and entirely impunctate (the flavous colour forming a broad triangular patch which extends to

the top of the elevation); scutellum shining, impunctate, black; elytra velvety-black, with a very

prominent trigonate tubercle at the middle of the base and three others placed triangularly at the apex

(the one nearest the suture the largest), the dise occupied by the usual oblique ridge (extending from the

shoulder to the suture where it forms a more than usually raised V-shaped prominence), the inner side of

which is fulvous, the space between the oblique ridge and the base remotely punctured and furnished

with some small fulvous tubercles, the suture deeply dentate ; the pygidium, the last abdominal segment,

as well as the sides of the other segments and some spots on the shoulders, flavous ; legs black, with a

flavous spot placed at the base and apex of the femora and tibie.

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

Only a single specimen of this remarkable Ch/amys was obtained. It seems to belong

to the group containing C. dromedarius, Koll., and others; the colour of the elytra is

probably subject to variation as regards the amount of fulvous or black.

44, Chlamys biplagiata. (Tab. XL. fig. 9.)

Black, the labrum, the basal joints of the antenne, and the tarsi fulvous; thorax granulate-punctate, the

elevation round; elytra with four or five longitudinal ridges, bright fulvous, a spot on the shoulder, and

a transverse band below the middle black.

Length 1 line.

Subcylindrical, slightly narrowed posteriorly ; head extremely finely granulate, entirely black; labrum and

_ palpi fulvous; antenne short, the lower five joints fulvous, the rest black; thorax with a regularly

rounded undivided central elevation, entirely black, the surface very finely punctured at the sides only,

the raised portion closely reticulate ; scutellum black ; elytra with four or five more or less distinct cost

in the usual position (the first two united by a transverse ridge at, and the third and fourth by a similar

ridge before, the middle), the interstices closely punctured and excavate, the surface fulvous, a round spot

at the shoulder, a short transverse band below the middle, abbreviated at the sides, and the suture, rather

broadly, black ; pygidium, underside, and legs black.

45. Chlamys multifasciata. (Tab. XL. fig. 10.)

Dark fulvous, with a slight purplish tint; thorax with a central longitudinal and a lateral semicircular black

band; elytra with a subsutural and a lateral short black band, the bands limited by strongly raised coste,

the interstices deeply punctured; the breast with a black lateral stripe.

Length 1? line.

Head finely rugose, the vertex with a narrow black central stripe; antenne with the first joint fulvous (the

rest broken off); thorax with the posterior portion only moderately raised and limited behind by a rather

deep transverse sulcation, the raised portion with a ridge on each side at the top, the surface rather

rugose, dark fulvous, the disc with a narrow black band, which extends from the top of the elevation to

the anterior margin, and some irregularly distributed black punctures, the sides with a semicircular black

band, the end of which extends to the lateral margin; elytra dark fulvous, with a slight purplish tint, partly

shining, closely foveolate-punctate on the disc, with a deep sulcation near the suture, extending from the

base to the middle, and an oblique lateral one below the shoulder, the sutural sulcation bounded on the

inner side by a strongly raised ridge (the commencement and end of which is marked by a tubercle) and

deep black within, and a trigonate tubercle near the suture close to the apex, the space between the first

and second grooves occupied by reticulations which are divided by less strongly raised coste, the suture

dentate throughout; the underside is impressed with shallow fovee ; the breast has a longitudinal stripe

on either side, and there are two oblique stripes on the abdominal segments; pygidium with two spots

at the base and two others near the apical margin ; tibiee with a small black spot at the middle.

Hab. Panama, Volcan de Chiriqui (Champion).

In this species the bands of the thorax and of the elytra are placed within the

grooves; the elytra have four longitudinal coste in the usual position, the spaces

between the costz closely foveolate-punctate, and the suture dentate throughout. One

specimen.

46. Chlamys quadricarinata.

Subquadrate, fulvous; thorax with seven obscure brown spots, its elevation with two ridges on each side, the

surface granulate-punctate ; elytra with four very strongly raised coste and some transverse ridges, these

surrounding excavate spaces, the latter remotely punctured; pygidium with a central and two lateral

carinations.

Length 12 line.

Head rugosely punctured, the labrum and other parts of the mouth black; antenne with the lower joints

fulvous (the rest broken off); thorax rather strongly narrowed anteriorly, the sides rectilinear, the disc

moderately raised behind but with the elevation abruptly deflexed posteriorly, the latter with a strongly

marked and a less distinctly raised ridge at the top (the inner one oblique, the outer one straight), the anterior

portion with some very obscure tubercles placed in a transverse row, the surface entirely covered with

deep punctures and of a pale fulvous-colour, marked with obscure, more or less longitudinal, dark brownish

spots, three on each side and one at the top of the elevation ; elytra with a rather deep sulcation extending

from below the shoulder towards the suture, four strongly raised coste (two running close to the suture

and connected by a transverse ridge at the middle, these being more widely separated anteriorly than

posteriorly and enclosing excavated spaces, and two in the usual position near and at the shoulder, these

latter being joined to the others), and a strongly raised transverse lateral ridge, the latter placed in a line

with the shorter subsutural ridge and sending off longitudinal cost towards the apex, the surface of a

rather bright fulvous colour here and there marked with paler stains, the interspaces between the coste

being darker and deeply but not very closely punctured; pygidium with a central longitudinal and a

shorter lateral carina; underside and legs entirely fulvous, the former closely foveolate-punctate.

Hab, Panama, Bugaba in Chiriqui (Champion).

CHLAMYS. 171

The single male specimen obtained by Mr. Champion is well distinguished from

similarly-coloured species by the sculpturing of the thorax.

47, Chlamys angulicollis. (Tab. XL. fig. 11.)

Obscure dark fulvous, opaque ; thorax finely granulate-punctate, with two lateral black bands, the posterior

angles tuberculiform ; elytra with two longitudinal coste (the first short and S-shaped) connected by

transverse short ridges, the apex with two tubercles.

Length 2 lines.

Head finely rugose, fulvous; antennz obscure fulvous, the last four joints black, the fourth and following

joints strongly transversely serrate; thorax with its middle portion gradually raised, the elevation

bounded at the base by a deep transverse groove, and with a rather acute edge behind, the posterior

angles produced into a blunt tubercle, the surface extremely closely and finely punctured and granulate,

reddish-fulvous, entirely opaque, with a black, anteriorly widened, dentate band on each side, extending

from the top of the elevation nearly to the anterior margin, and a small very obscure black spot near the

lateral margin ; elytra of a paler colour than the thorax, rather closely impressed with black punctures,

and with two distinctly raised costee—the first S-shaped, near the suture (its commencement marked by a

tubercle), and joined at the middle by a short transverse ridge to the second costa, the latter commencing

at the middle of the base and extending nearly to the apex where it ends in a tubercle,—the shoulders

also costiform and with a short black stripe (if looked at sideways, the elytra also appear to have a

transverse ridge before the middle, this ridge connecting the second costa with the more indistinct

lateral ones, and a ridge at the sides below the transverse one); pygidium rather remotely punctured ;

underside and legs dark brown, with black markings in the coxal cavities.

Hab. Guatemata, San Gerénimo (Champion).

A single specimen.

The black bands and shape of the thorax, in connection with the two plainly marked

elytral costa, separate C. angulicollis from any of its congeners.

48. Chlamys gaumeri.

Cylindrical, obscure fuscous; thorax transversely convex, the elevation reticulate-punctate and scarcely

perceptible ; elytra closely punctate and reticulate, without tubercles and with very indistinct ridges, a

black spot on either side of the suture near the base.

Length 17 line.

Head finely rugose, obscure fulvous, with a small indistinct fuscous spot on the vertex ; anterior margin of the

epistome black ; labrum testaceous ; antenne fulvous, the terminal joints darker ; thorax subcylindrical,

regularly convex, the middle portion scarcely perceptibly raised, the surface of a dull brownish-fuscous

colour, closely reticulate on the disc, finely punctured at the sides; elytra of the same colour as the

thorax, with some slightly raised ridges, of which two extending from the middle of the base to near the

apex are more plainly marked than the rest, the former limiting externally a black smoother space placed

below the scutellum, the rest of the surface closely and deeply punctured and reticulate, the suture

dentate throughout ; pygidium closely punctured, and with two very short coste at the base; underside

and legs coloured as above, the former closely reticulate.

Hab. Mexico, Temax in North Yucatan (Gawmer).

The feebly raised thoracic elevation and indistinct elytral ridges, the subcylindrical

shape, and the very dull fuscous colour distinguish C. gawmeri from any of its congeners.

One example only, a female, has been received.

There can be little doubt that Chlamys conspersa, Mannerh., and Exema dispar, Lac.,

4, Exema octocarinata.

Black; thorax with eight ridges, the two lateral ones interrupted; scutellum not visible; elytra each with

four longitudinal coste on the disc and some shorter coste towards the apex, the interstices strongly

punctured anteriorly.

Length 4—# line.

Hab. Panama, Volcan de Chiriqui (Champion).

This small species differs from all its allies in the absence of a visible scutellum, and

a new genus seems almost required for its reception. The head is minutely granulate

and finely punctured. The thorax has its median lobe prolonged and acutely pointed

and extending to the usual position of the scutellum (the species thus differing from all

others of the genus known to me); on the disc are four strongly raised coste radiating

from the base towards the anterior margin, the sides being furnished with a short ridge

anteriorly and a longer but interrupted one placed more inwards; the interstices are

impressed with single rows of fine punctures. The scutellum is not visible. The

elytra have altogether about eight longitudinal coste, of which three are entire; the

first two coste are joined below the middle near the suture by a short transverse ridge,

and the second is also joined to the third and fourth by an oblique transverse ridge

before the middle; the posterior portion of the elytra is furnished with numerous

shorter longitudinal coste; the interstices between these latter are foveolate-punctate,

while those of the anterior portion are closely and strongly punctured ; the suture is

LAMPROSOMA (p. 90).

Lamprosoma nicaraguense (p. 91).

To the localities given, add:—Muxtco, Teapa in Tabasco (H. H. Smith), Almolonga

(Hoge).

Mexican specimens are of a bright metallic green colour, and differ from those from

Guatemala and Nicaragua in the shape of the golden-cupreous band of the thorax, this

band, instead of being confined to the sides only, extending very narrowly along the

anterior margin. L. nicaraguense may also be known by the underside being entirely

bright reddish-golden. ;

Lamprosoma sallzi (p. 91).

To the Mexican locality given, add :—Ventanas in Durango, Acapulco in Guerrero

(Hoge).

‘This species greatly resembles the Mexican form of L. nicaraguense; but may be

known from it by the thorax being almost impunctate, and with the aureous colour

more extended, and by the abdomen being nearly black. The specimens from Acapulco

are somewhat smaller and of a more leaden-blue colour, and they have the aureous

lateral markings of the thorax not so broad and more obliquely shaped ; it is probable,

however, that this is only due to local variation. |

2 (a). Lamprosoma bugabense.

Above leaden-blue, the head, sides of the thorax, apex of the elytra, and the underside and legs golden-reddish-

eupreous; thorax strongly transverse, finely punctured; elytra finely punctate-striate, the interstices

minutely aciculate.

Length 22 lines.

Hab. Panama, Bugaba in Chiriqui (Champion).

This species is so closely allied to L. nicaraguense and L. sallei, that it is only

necessary to point out the differences: the colour of the upper surface is leaden-blue

(in one specimen the elytra are duller than in the other) ; the head is minutely and

174 PHYTOPHAGA.—SUPPLEMENT.

closely granulate and punctured; the thorax is much more transverse, being, at the

base, more than three times as broad as long, and is impunctate at the sides and finely

punctured at the middle; the elytra have their interstices finely scratched or aciculate,

and the golden-cupreous band at the apex is shorter and narrower; and the prosternum

is narrower and much more strongly punctured.

Lamprosoma hypochryseum (p. 92).

A specimen obtained by Herr Hége at Cuernavaca during his second expedition

differs from the typical form in being of a greenish-blue colour above, and in having

the elytra more strongly punctured.

Lamprosoma gratum (p. 92).

A specimen lately received from Northern Yucatan (Gauwmer) differs from Lacor-

daire’s description in having the prosternum scarcely one half longer than broad:

Lacordaire gives the length as at least twice as long as broad, which, I think, is

erroneous. |

Lamprosoma chapuisi (p. 92).

To the locality Panama, add :—vVolcan de Chiriqui, Boquete, Caldera (Champion).

Specimens from these additional localities differ from the type in the greater extent

of the metallic colour of the thorax; in some of them the tarsi show a slight metallic

gloss.

contained in the Sallé collection (both formerly belonging to that of Sturm and

labelled by him LL. superbum), and a third has been found at Tonila by Herr Hoge;

these specimens agree well with Lacordaire’s description, although in one the thoracic

blue spot is narrowly transverse and undivided. JI must further add that in these

examples the head has a triangular depression at its lower portion, a character not

mentioned by Lacordaire.

13(a). Lamprosoma imitans.

Lamprosoma opulentum, buj. op. p. 94 (partim).

Metallic green ; head and legs green, the former finely granulate ; thorax with a narrow transverse violaceous

LAMPROSOMA. 175

band; elytra distinctly punctate-striate, a transverse band at the base, and another at the middle, and a

sutural spot at the apex, dark violaceous; abdomen black.

Length 2 lines.

Head flattened, finely granulate and opaque, subremotely punctured, the anterior margin of the epistome nearly

straight ; the base of the mandibles metallic green; antenne black, the basal joint metallic green above ;

thorax impressed with a few scarcely perceptible punctures, metallic green, the middle of the disc with a

narrow (sometimes divided) dark violaceous band ; elytra rather elongate, narrowed posteriorly, somewhat

strongly punctate-striate, with two transverse bands (the first occupying less than the basal third of the

elytra, the second, placed at the middle, not extending to the lateral margin and more or less widened

outwardly), a subapical spot placed across the suture, and the latter itself, narrowly, violaceous ; the

abdomen and tarsi black; the prosternum longer than broad, nearly smooth, and shining.

Hab. Mexico, Juquila (Sallé).

L. imitans, I have no doubt, is quite distinct from ZL. opulentum; the head is flat

and has no depression at its lower portion, and the elytral markings are quite different

in shape and position. ‘Three specimens have been received from Juquila; a fourth,

without exact locality, contained in my own collection, resembles these, but has the

head bright metallic cupreous, and the thorax distinctly punctured; the latter may

prove to be distinct.

Lamprosoma refulgens (p. 95).

To the Mexican localities given, add:—Acapulco (Hége); Panama, Bugaba

(Champion). |

The Guatemalan locality given is erroneous; it refers to L. guatemalense. A single

specimen obtained by Mr. Champion at Bugaba seems only to differ from those from

Mexico in its rather smaller size.

14 (a). Lamprosoma aureolimbatum.

Black ; the head and thorax reddish-cupreous, finely punctured ; elytra distinctly punctate-striate, violaceous-

blue, a small spot at the middle of the base and the sides (rather narrowly at the base but gradually

becoming more broadly so towards the apex) golden-cupreous,

Length 2 lines.

Head extremely minutely granulate, finely but not very closely punctured, bright reddish-cupreous, the

anterior edge of the epistome nearly straight and narrowly black; antenne black, the basal joint fulvous

below; thorax punctured like the head (without being granulate), very shining, bright reddish-cupreous ;

scutellum black; elytra with rather deep punctured stris, violaceous-blue, with the sides from the base to

the apex, but gradually becoming more broadly so posteriorly, golden-cupreous ; underside and legs

entirely black.

Hab. Mexico, Tapachula in Chiapas (Hége).

This species, of which a single specimen only was obtained, may be at once distin-

guished from L. refulgens and the allied species by the shape of the cupreous limb of

the elytra (the cupreous colour extending upwards to the base), and by the entirely

black underside and legs; at the middle of the base of each elytron there is another

small cupreous spot.

Lamprosoma bifasciatum (p. 95).

To the Mexican localities given, add :—Acapulco (Hége).

Lamprosoma guatemalense (p. 96).

To the locality given, add :—Muexico, Tapachula in Chiapas (Hége) ; GUATEMALA,

Teleman in Vera Paz (Champion).

The single specimen obtained by Herr Hége does not differ materially from those

from Guatemala.

18 (a). Lamprosoma dubiosum.

Broadly rounded, black ; the head and thorax (a spot at the base excepted) reddish-cupreous ; elytra violaceous-

blue, distinctly punctate-striate, the apex with a common cupreous transverse band.

Length 14-14 line.

Hab. Panama, Bugaba, Caldera (Champion).

Two examples. This insect almost agrees in coloration with L. guatemalense, but

differs from it in its broadly rounded shape and in the elytra being very obtuse behind.

The apical portion of the latter in L. guatemalense is also more strongly punctured and

somewhat rugose; in L. dubiosum it is very finely punctured. The two species are

smaller than any of the other similarly-coloured allied forms. In one specimen of

LL. dubiosum the thorax has nearly the entire middle of the disc violaceous-blue; in the

other this colour is reduced to a small spot at the base.

20 (a). Lamprosoma femoratum.

Lamprosoma testudineum, huj. op. p. 97 (partim) (nec Lacord.).

Black below; above dark violaceous or blue; head finely granulate, the epistome deeply emarginate ; thorax

finely and remotely punctured ; elytra finely punctate-striate; anterior femora angulate near the base;

prosternum slightly longer than broad.

Length 23-3 lines.

Hab. Mexico, San Andres Tuxtla, Playa Vicente (Sad/é), Almolonga (Hoge).

Our Mexican specimens of this insect were referred in the earlier portion of this

work to L. testudinewm ; but a more careful examination has convinced me that they

are distinct from that species and apparently undescribed. The principal differences

are the deeply emarginate epistome, the sides of which are prolonged into an acute

point; the largely developed mandibles; and the enlarged and subangulate anterior

femora. There is only one species described by Lacordaire (Z. azureum) which has

similarly-formed femora; L. azwrewm, however, has the thorax and elytra finely granu-

late. In the present species the colour of the upper surface varies from violet to

blackish-blue, and the general shape is broad ovate and but slightly narrowed poste-

riorly. The head alone is minutely granulate and finely punctured, with or without a

fovea at its lower portion; the antenne are black and have the underside of the first

LAMPROSOMA. Li7

joint and the second one entirely more or less fulvous; the thorax is very finely and

rather remotely punctured ; the elytra are finely punctate-striate; and the prosternum

is rugosely punctured. ‘hese characters are constant in the seven specimens .before

me. The legs have a bluish gloss in some examples. L. amethystinum, Lac., seems

to be a closely-allied but distinct species.

Lamprosoma approximans (p. 97).

To the Mexican locality given, add:—Ventanas in Durango, Chilpancingo in

Guerrero (Hoge), Puebla (Sallé). 7 |

The specimens obtained by Herr Hoge differ from the others in being of a bright

metallic green colour above; but in the produced shoulders and extremely fine punc-

tuation they agree with the typical form.

Lamprosoma amabile (p. 99).

In a specimen obtained by Mr. Gaumer in Northern Yucatan the thorax is of a

darker and more leaden hue than the elytra; and the prosternum is scarcely longer

than broad, rather convex, excavate in front, almost smooth, with a few punctures only

on the surface.

Lamprosoma pediculus (p. 101).

A further examination of the specimens referred by me to this species proves that

they cannot well be identified with it, if Lacordaire’s description is correct, as the head

and thorax show a distinct punctuation; our localities for L. pediculus refer to the

following two species :—

35 (a). Lamprosoma juvencum.

Lamprosoma pediculus, huj. op. p. 101 (nec Lacord.).

Ovate, scarcely narrowed posteriorly, black ; above metallic cupreous ; head minutely granulate and punctured ;

thorax extremely finely punctured; elytra distinctly punctate-striate, the interstices very minutely

punctured ; prosternum not longer than broad, finely punctured.

Length 14 line.

Hab. Mexico, La Parada, Oaxaca (Sallé), Playa Vicente (Hége).

L. juvencum agrees in size with L. pediculus, but differs from it in the finely

granulate and punctured head (the punctures quite distinct when seen under a strong

lens); the punctuation of the thorax is very minute, and the interstices are not

granulate but shining; the elytra have their apex broadly rounded, and the surface

very distinctly punctate-striate, some minute punctures being also visible on the inter-

stices. Lacordaire says that L. pediculus has a nearly impunctate head and thorax,

even when examined under a powerful lens.

35(s). Lamprosoma ovulum.

Lamprosoma pediculus, huj. op. p. 101 (nec Lacord.).

Ovate, narrowed behind, black ; above bright reddish-cupreous ; head shining, finely punctured ; thorax finely

_ and distinctly punctured ; elytra strongly and remotely punctate-striate ; prosternum longer than broad,

longitudinally sulcate.

Length 14 line.

Hab. GuatemaLa, Chacoj in Vera Paz (Champion).

‘Of the same size as . guvencum, but distinctly narrowed behind. ‘The head is finely

punctured (not granulate), the space between the eyes proportionately narrow. The

thorax is also finely but distinctly punctured, and the punctures are remotely placed.

The punctuation of the elytra is proportionately strong, and the punctures are rather

widely separated. The prosternum is quite different in form from that of L. juvencum,

it being longer than broad and longitudinally sulcate.

35 (c). Lamprosoma pusillum. |

Ovate, slightly narrowed behind, black ; above bright cupreous; head impunctate, the anterior margin of the

epistome raised into a ridge; thorax distinctly punctured; elytra strongly punctured, the interstices

_ finely punctate; prosternum slightly longer than broad ; claws simple.

Length 1 line.

Hab. Panama, Bugaba (Champion).

Of short, convex shape, scarcely narrowed behind, and separated from L. ovulum by

the impunctate head and the narrow but distinct transverse ridge which forms the

anterior margin of the epistome; the antenne have the first joint metallic above, the

rest black; the thorax is much more distinctly punctured than in Z. juvencum and

L. ovulum ; the punctuation of the elytra is strong and deep, and the punctures are

closer than in L. ovulum. The claws in the present species appear to be simple. In

one specimen the head and the anterior legs are metallic green. | |

85(p). Lamprosoma intermedium.

Oblong-ovate, slightly narrowed posteriorly, black ; above metallic reddish-cupreous; head and thorax finely

punctured ; elytra strongly punctate-striate, the interstices finely punctured; prosternum slightly broader

than long, finely punctured.

Length 13-1? line.

Hab. Mexico, J nquila (Flohr), Ohilpancingo in Guerrero (H. H. Smith), La Parada

(Sallé).

Of somewhat elongate shape, scarcely narrowed behind, and distinguishable from

L. pediculus, Lac., by the finely punctured head and thorax and the shape of the

prosternum. ‘The head, when seen under a strong lens, is minutely granulate and

very finely punctured, with a shallow depression at its lower portion; the thorax is as

finely punctured, except near the base where the punctures are stronger, the median

lobe not very acutely produced but somewhat rounded; the elytra are only moderately

convex, broadly rounded at the apex, their punctuation distinct, the interstices also

here and there extremely finely punctured ; the entire underside and the legs are black ;

the prosternum is broader than long (this and the punctured elytral interstices distin-

guish L. intermedium from several other closely allied forms) and finely punctured. In

the specimen from La Parada the thorax is much more strongly punctured, and the

elytral interstices are also much more distinctly (though finely) punctate ; this example,

although of similar shape, is broader than the others ; it is probably a female of the

same species.

36 (a). Lamprosoma chiriquense.

Very convex, narrowed behind, black; above bright metallic green; head and thorax very finely punctured ;

elytra rather strongly punctate-striate ; prosternum slightly longer than broad, smooth.

Length 3 lines.

Hab. Panama, Volcan de Chiriqui (Champion).

This large-sized Lamprosoma, of which Mr. Champion obtained but a single spe-

cimen, is closely allied to LZ. salvini and also to several species described by Lacordaire.

In shape it is very different from L. salvini, the latter being very much less convex and

more evenly rounded; in L. chiriquense the greatest convexity of the elytra is at the.

base, the entire posterior portion being strongly.deflexed. The head.is finely and

closely punctured, and has an obscure short central groove; the epistome is continuous

with the front, its anterior margin being moderately emarginate (in L. salvini the

angles are prolonged into points); the antenne are short, black, the underside of the

first joint, and the second one entirely, fulvous, the basal joint strongly widened. The

thorax has its median lobe rather more pointed than in L. salvini, and also has two

rather distinct depressions at the base in the middle; it is as finely punctured as the

head, except near the base, where the punctures are, as usual, stronger. ‘The elytra

are punctured as in L. salvini. The prosternum is smooth, narrowed posteriorly, and

excavate at its anterior portion.

36 (Bs). Lamprosoma opacicolle.

Ovate, scarcely narrowed posteriorly, black; the head and the legs reddish-cupreous, the thorax greenish-blue,

and the elytra dark plumbeous, the sides of the thorax and the apex of the elytra reddish-cupreous ; thorax

opaque, impunctate; elytra strongly punctate-striate ; prosternum scarcely broader than long.

Length 1 line. .

Head very finely granulate, with a few scarcely perceptible punctures ; labrum and mandibles black; antenna

scarcely extending to half the length of the thorax, black, the first joint cupreous ; thorax extremely

finely granulate, opaque, of a dull greenish-blue colour, the sides, but more narrowly so at the base,

reddish-cupreous; elytra of a bluish-plumbeous colour, more shining than the thorax, very strongly

punctured, the interstices slightly rugose and with a few fine punctures, the sides with a metallic cupreous

band extending from below the middle to the apex; the underside and tarsi black ; ‘Prosteraum slightly

broader than long, with a few fine punctures and hairs.

Hab. Panama, Volcan de Chiriqui (Champion).

‘180 PHYTOPHAGA.—SUPPLEMENT.

L. opacicolle differs from the similarly-coloured allied forms in the shape of the

prosternum, and in the opaque and impunctate thorax, dull leaden colour of the elytra,

bright red, but not very shining, head and sides of the thorax, and posteriorly broad

shape. One specimen.

36 (c). Lamprosoma angustatum.

Ovate, strongly narrowed posteriorly, black, above reddish-cupreous; head and thorax finely punctured ; elytra

finely punctate-striate ; prosternum broader than long.

Length 2} lines.

Head extremely finely granulate, finely and rather closely punctured, the anterior margin of the epistome

nearly straight, the parts of the mouth black; antenne black, the basal joints fulvous below; thorax

strongly transverse, very finely and remotely punctured at the sides, more closely and strongly so on the

disc ; elytra much narrowed posteriorly, finely punctate-striate, the interstices somewhat aciculate ; under-

side and legs black ; prosternum distinctly broader than long, with a few punctures.

Hab. Paxama, Caldera in Chiriqui (Champion).

I am unable to refer this insect, of which only a single specimen was obtained, to

any described species, owing to its posteriorly narrowed shape and broad prosternum,

the latter in most of the similarly-coloured congeners being longer than broad. In the

example before me there is an obscure dark band at the base of the thorax which i is

probably accidental.

86 (p). Lamprosoma constrictum.

Ovate, strongly convex, much narrowed posteriorly, bright metallic green ; antenne and abdomen black ; head

and thorax strongly punctured; elytra deeply punctate-striate, the interstices obsoletely aciculate; pro-

sternum excavate.

Length 2 lines.

Of very convex and posteriorly narrowed shape, bright metallic green ; head minutely granulate and strongly

but not very closely punctured, the epistome strongly deflexed, deeply emarginate anteriorly, the labrum

and mandibles black; antenne black, the first joint below and the second one entirely fulvous ; thorax

short, very strongly transverse, the median lobe rather rounded and with a depression near its apex, the

surface punctured like that of the head; elytra only half as wide at the apex as at the base, strongly

punctate-striate, the interstices irregularly and ubsoletely aciculate, the lateral lobe moderately produced

and not very pointed ; underside black, the sides of the metasternum and the femora metallic greenish ;

prosternum quadrate, excavate throughout its entire length, and punctured.

Hab. Guatemata, Panzos in Vera Paz (Conradt).

The strongly punctured head and thorax and the excavate prosternum, in connection

with the posteriorly narrowed shape, separate this species from any of its 's similarly-

coloured allies. One example.

36 (c). Lamprosoma unicolor.

Broadly ovate, metallic violaceous-blue; head and thorax minutely and closely punctured; elytra finely

punctate-striate, the interstices obscurely aciculate ; prosternum subquadrate, deeply excavated.

Length 2 lines.

Head very finely and closely punctured ; the epistome separated from the face by an obscure transverse groove,

a little more strongly punctured than the rest of the head, its anterior margin moderately concave-

emarginate; the eyes very fecbly notched; antenne black, the first joint partly fulvous below ; thorax

punctured like the head ; elytra moderately convex, their apex broadly rounded, the disc finely punctate-

striate.

Hab. Guatemata, Santa Ana on the Rio Negro (coll. Jacoby).

The broadly ovate, scarcely narrowed shape, the blue underside and legs, and the

broad and deeply excavated prosternum distinguish Z. wnicolor from all the other

species of the genus here enumerated. A single specimen, received from the Stuttgart

Museum.

36(r). Lamprosoma aterrimum.

Very convex, narrowed posteriorly, entirely black ; head and thorax finely and sparingly punctured ; elytra

very finely punctate-striate, the interstices smooth; prosternum scarcely longer than broad, flat.

Length 24 lines. .

Hab. Nicaraaua, Chontales (Janson).

Of an entirely black colour, and therefore easily distinguishable from any other

species of the genus. The head is very finely and remotely punctured, the anterior

margin of the epistome moderately emarginate ; the thorax is only visibly punctured

near the median lobe, the latter itself being rather rounded; the elytral punctuation is

only visible under a strong lens; the prosternum is somewhat rugose in front, for the

yest smooth and shining. If looked at sideways, the greatest convexity of the elytra is

at the base. A single specimen.

finely punctured ; elytra blackish-violaceous, distinctly punctate-striate at the base, the apex almost

impunctate.

Length 3 line.

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

This small species differs from LZ. godmant in being more narrowed posteriorly and

in having the head very finely granulate. The head is sometimes black, frequently

metallic greenish, with a fine longitudinal groove down the centre. The elytra have a

violaceous or bluish tint, and the punctuation is only distinct near the base, and

almost entirely obliterated below the middle; in LZ. godmani the punctures are distinct

to the apex, and the interstices are also sparingly and very finely punctured (scarcely

rugose, as given in the description). The prosternum is subquadrate, and has a few

fine punctures.

42(s). Lamprosoma verepacis.

Black; head greenish, finely granulate; thorax finely and rather closely punctured ; elytra narrowed poste-

riorly, very finely punctate-striate ; prosternum constricted at the middle, longer than broad.

Length 2 line.

Hab. Guatemata, San Gerénimo (Champion).

Of posteriorly less narrowed shape than L. atro-violaceum, almost entirely black, the

thorax more distinctly and closely punctured ; but principally distinguished from that

species by the elongate and distinctly constricted prosternum. The head is minutely

eranulate, of a metallic greenish colour, and impressed with a few punctures (but

not with a longitudinal groove). The underside, instead of being distinctly punctured,

as in several of the allied species, is entirely impunctate.

Lamprosoma modestum (p. 104).

To the locality given, add :—Panama, Boquete (Champion).

A specimen subsequently received from the State of Panama is slightly larger and of

somewhat broader shape than the Guatemalan type.

45. Lamprosoma punctifrons.

Ovate, very convex, narrowed behind, black; above metallic cupreous; head greenish, strongly punctured ;

thorax closely and finely punctured; elytra strongly punctate-striate, the interstices finely punctured ;

prosternum slightly longer than broad, narrowed at the middle.

Length ? line.

Hab. Panama, Caldera in Chiriqui (Champion).

The head in this small species is very strongly punctured near the eyes; the latter

are large and their diameter is equal to that of the space dividing them, this space

being extremely finely granulate and having a longitudinal groove down the centre.

The thorax is three times as broad as long; its median lobe is very little prominent or

produced, the margin on each side of it being slightly sinuate; the surface is closely

and finely punctured. ‘The elytra are more strongly punctured than the thorax, and

the interstices each bear a single row of finer punctures. The underside is black,

the meso- and metasternum finely and remotely punctured; the prosternum is

elongate.

OOMORPHUS. (To follow the genus Lamprosoma, p. 105.)

Three species are at present placed in this genus, which principally differs from

OOMORPHUS.—CHRYSODINA. 183

Lamprosoma in the short eighth joint of the antenne and in the simple claws. The

two species from Central America referred to it seem to possess these characters, as

well as wings, and they are of somewhat more elongate shape than their Old-World

congeners,

1. Oomorphus mexicanus.

Oblong, subcylindrical, dark neous ; the basal two joints of the antenne fulvous; head and thorax almost

impunctate; elytra finely punctate-striate, greenish-zeneous.

Length ? line.

Head entirely impunctate; eyes entire; antenne extending to the base of the thorax, black, the lower two or

three joints fulvous ; thorax more than twice as broad as long, the sides straight but slightly converging

towards the apex, the base oblique on each side and with the median lobe scarcely pointed, the surface

exceedingly finely punctured (the punctuation only visible under a very strong Jens) ; scutellum scarcely

visible; elytra cylindrical, very little narrowed posteriorly, not lobed at the sides, the punctuation

fine but distinct, but stronger at the base than near the apex, the interstices also with some minute punc-

tures; underside blackish-zeneous ; the prosternum broad, a little longer than wide, and longitudinally

sulcate throughout its entire length; abdomen finely pubescent.

Hab. Mexico, Chilpancingo and Omilteme in Guerrero (H. H. Smith).

The unnotched eyes and the absence of a lateral lobe to the elytra, together with the

‘subcylindrical shape, will help to distinguish O. mexicanus from any species of

Lamprosoma.

2. Oomorphus hirtipes.

Oblong, black; above and the prosternum and tibie dark eneous; antenne obscure fulvous, the apical joint

black; head and thorax finely punctured ; elytra strongly punctate-striate; tibiee with long grey hairs;

prosternum quadrate.

Length 13 line.

Hab. Panama, Volcan de Chiriqui ( Champion)

Much larger and more robust than 0. mexicanus ; the head extremely finely granulate

and punctured ; the eyes entire; the antenne differently coloured; the elytra much

more strongly punctured and with smooth interstices; the tibie and the prosternum

obscure seneous, the former with a long fringe of greyish hairs along their outer edge.

Closely allied to C. festiva ; but differing from it in the unicolorous and much les

deeply punctured head (in C. festiva the space above the insertion of the antenne and

part of the epistome is metallic blue), and in the much broader prosternum. Many

specimens, including the type.

The general colour of the upper surface is better described as cupreous rather

than wneous.

Chrysodina ornata (p. 107).

To the Mexican locality given, add:—Ventanas in Durango (Forrer), Iguala and

Mescala in Guerrero (Hége).

In the specimens obtained by Herr Hége the cupreous colour at the sides of the

elytra does not extend quite so far upwards as in the type.

Chrysodina ornaticollis (p. 108).

To the Mexican localities given, add:—Amula in Guerrero (H. H. Smith).

C. ornaticollis seems subject to great variation, and it is scarcely possible to say

whether all the specimens before me really belong to one species. ‘The punctuation

of the head in the example from Playa Vicente is very strong, in that of one from

Guanajuato quite fine. The specimen from Amula has entirely fulvous antenne and

legs, yet in general shape and other particulars it does not differ from the rest.. In

general shape, C. ornaticollis is cylindrical, convex, and rather more elongate than most

of its congeners.

8 (a). Chrysodina cyanipennis.

Black ; the basal joints of the antenna, the apex of the tibiae, and the tarsi, fulvous; thorax metallic cupreous,

strongly punctured ; elytra metallic blue, strongly punctate-striate.

Length 1 line.

Head metallic green or blue, rather strongly and remotely punctured; the vertex strigose; the clypeus

triangular, coarsely punctured ; the labrum fulvous; the antenne extending to beyond the middle of the

body, the lower five joints fulvous, the rest black, thickened; thorax strongly transverse, the sides

moderately rounded, narrowed anteriorly, and here rather strongly deflexed, the surface bright aureous

or cupreous, rather deeply and closely punctured; scutellum violaceous, broad; elytra more strongly

punctured than the thorax, metallic blue, the punctures arranged in closely approached, rather regular

rows; underside black, the sides of the breast and the legs metallic blue; the apex of the tibie and

the tarsi fulvous. .

Hab. Mexico, Acapulco in Guerrero, Tacambaro in Michoacan (Hoge).

This species is similarly coloured to C. ornaticollis; but is only half the size, and has

the thorax and elytra more deeply punctured. The legs (including the tarsi) also differ

in colour; the specimen from Tacambaro, however, has unicolorous tibie.

Chrysodina pubescens (p. 108).

To the Mexican locality given, add :—Tupataro and Irapuato in Guanajuato (Hége).

CHRYSODINA, 185

Of this curious species more than twenty specimens were obtained by Herr Hoge

during his second expedition.

9 (a). Chrysodina pilosa.

Carysodina pilosa, Lefévre, Bull. Soc. Ent. Fr. 1887, p. clv °.

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion ').

This is a pubescent species which differs from C. pubescens in the closely punctured

and more shining elytra and their much longer pubescence ; the thorax is very strongly

rugose-punctate, and the elytra are finely granulate, with more distinct rows of punc-

tures; the pubescence is long, silky, and whitish in appearance.

9 (ps). Chrysodina fulvicornis.

Below blackish, the sides of the breast and abdomen metallic greenish, the antenne and legs fulvous; thorax

reddish-cupreous, minutely punctured ; elytra metallic green, rather remotely punctate-striate.

Length 1] line.

Of subcylindrical, oblong shape; the head metallic green, rather strongly but not very closely punctured, the

space above the insertion of the antenne obscure cupreous; labrum and palpi fulvous; antenne scarcely

extending beyond the base of the thorax, fulvous, the last five joints thickened ; thorax strongly transverse,

widened at the middle, the sides moderately rounded and narrowed towards the apex, the surface extremely

finely and rather remotely punctured, bright reddish-cupreous; elytra metallic greenish, proportionately

strongly punctate-striate, the punctures becoming finer towards the apex, and (like the striz) somewhat

remotely placed; legs fulvous.

Hab. Mexico, Cerro de Plumas (Hége). A single specimen.

C. fulvicornis differs from C. championi and C. ornaticollis in its smaller size and

different shape, and in the fulvous antenne and legs.

Chrysodina purpureicollis (p. 109).

To the Mexican localities given, add :—Pinos Altos in Chihuahua (Buchan-Hepburn),

Ciudad in Durango (Forrer), Juquila (Flohr), Zacualtipan in Hidalgo, Jalapa (Hége).

Chrysodina cupriceps (p. 109).

To the localities given, add:—Mexico, Tapachula in Chiapas (Hége).

The broad, oblong shape, less transverse thorax, proportionately long antenne, broad

scutellum, and medially constricted prosternum, give C. cwpriceps a very different facies

to the other members of the genus Chrysodina; it might, perhaps, equally well be

placed in Noda, near NV. curtula, Jac., a species of nearly similar shape and structure.

Chrysodina minuta (p. 110).

This species was provisionally placed by me in Chrysodina, although the more elongate

shape and long prosternum suggest the possibility of its requiring another genus for its

cannot find its place in that genus, owing to its elongate shape and the thickened

terminal joints of the antenne, the filiform antenne being one of the principal

characters of Lamprospherus. If M. Lefévre’s view is adopted, the Lamprospherus

described by me as minutus will require a new name.

15. Chrysodina nana.

Blackish, the labrum, antenne, and legs fulvous, above greenish-geneous ; the head remotely, the thorax finely

and more closely, punctured ; elytra regularly punctate-striate, the punctuation diminishing towards the

apex.

Length 1 line.

Of oblong and subcylindrical shape; the head finely and remotely punctured, the epistome more strongly

punctate, the latter triangularly emarginate at its lower edge ; labrum fulvous ; antenne rather long and

robust, fulvous, the terminal joint darker; thorax transverse, narrowed in front, the sides rounded, the

anterior angles acute but not produced, the surface finely, evenly, and rather closely punctured ; elytra

regularly punctate-striate, the punctures rather strong near the base, gradually becoming finer towards

the apex, the interstices smooth ; prosternum broad, nearly quadrate.

Hab. Mexico, Tapachula in Chiapas (Hége).

I include this very small species in Chrysodina (although from its general shape it

might almost equally well be placed in Noda), owing to its regularly punctate-striate

elytra and broad quadrate prosternum. It differs from the closely-allied C. minuta,

Jac., by the thorax being less transverse, more narrowed anteriorly, and more finely

punctured, and by the elytral strie being more regular and less closely punctured.

The general shape of the insect is also shorter and broader than in the allied species.

16. Chrysodina pusilla.

Oblong, blackish-sneous, above light bronze; antenne and legs fulvous; head and thorax rather strongly

punctured ; elytra regularly punctate-striate, the punctures finer towards the apex.

Length 1 line.

Head minutely granulate, rather strongly punctured, with a transverse depression between the eyes; labrum

fulvous ; antenne not extending to half the length of the elytra, fulvous, the second to the sixth joints

short, equal, the terminal joints strongly thickened ; thorax moderately transverse, the sides rounded,

narrowed in front, the surface punctured like that of the head, the punctures somewhat oblong in shape ;

elytra oblong, subcylindrical, convex, the punctures coarser and of more rounded shape than those of the

thorax, but becoming finer towards the apex, where they form single and remotely placed rows, the shoulders

rather prominent and angular, the submarginal interstices convex; legs robust, fulvous, the basal joints

of the front and middle tarsi much widened in the male; prosternum very broad, subquadrate, rugosely

punctured.

Hab. Panama, Tolé, Petia Blanca (Champion).

This species resembles C. minuta, Jac., in colour; but in the latter the thorax is

still more transverse, and its sides are more strotigly rounded near the apex. In

C. pusilla the head is much more fitely and closely punctured than in C. minuta, and

the thorax is minutely granulate; the antennee of the female generally have the

CHRYSODINA. | 187

seventh joint and also the apical one obscure fuscous. One specimen is of a violaceous

colour above, but does not otherwise differ from the rest.

17. Chrysodina vicina.

‘Blackish-eneous, above bright metallic green, the basal joints of the antenne fulvous; thorax finely and

closely punctured; elytra strongly punctate-striate.

Length 14 line.

Cylindrical and convex, proportionately short; head distinctly but not closely punctured ; eyes widely distant,

notched; mandibles robust, piceous; antenne rather short, the lower five joints fulvous (the basal one

metallic blue above), the others black, the latter transversely widened ; thorax transverse, convex, twice

as wide at the base as at the apex, the sides but slightly rounded, the surface evenly, closely, and finely

“punctured; scutellum broader than long, smooth; elytra convex, with an obscure depression, the surface

with deep, rather strong, and closely-placed rows of punctures, the punctures gradually becoming finer

towards the apex, the submarginal interstices rather strongly gostate; legs dark bluish-green ; prosternum

longer than broad.

Hab. Mexico, Chilpancingo in Guerrero (Hége).

Very closely allied to, and perhaps only a local variety of, C. hegei, from which it

differs in the dark blue or greenish legs, and in the finely punctured and more trans-

versely shaped thorax. In C. hegei the legs are entirely fulvous.

18. Chrysodina atro-violacea.

Bluish- or violaceous-black, the lower four or five joints of the antennz fulvous; head opaque; thorax im-

punctate ; elytra finely punctured, the punctuation becoming almost obsolete towards the apex; legs

violaceous-black.

Length 3—1} line.

Hab. Panama, Bugaba, David, Caldera, Tolé, Taboga Island (Champion).

According to Lefévre, who kindly examined our specimens, this is only a variety of

his C. levicollis ; but in my opinion it is specifically distinet, The colour of the insect

is blackish-blue or blackish-violaceous, with the exception of the basal joints of the

antenne. In C. levicollis the apices of the tibie and the tarsi, as well as the antenne,

are rufous; in more than twenty specimens obtained of the present insect, the legs

(including the tarsi) are violaceous-black. In C. atro-violacea the head is entirely opaque,

with a few scarcely perceptible punctures, the front generally impressed with a more

or less distinct oblong depression ; the thorax is impunctate (but shows some minute

punctures in the female); the elytra have the punctuation remote and only visible on

the anterior half, and the submarginal interstice convex; the legs are coloured like

the underside. C. atro-violacea differs, therefore, from C. levicollis in the black apical

joints of the antenne, the violaceous-black colour of the upper and undersides, and in

the unicolorous legs.

188 PHYTOPHAGA.—SUPPLEMENT.

The antenne in this species are much more elongate and slender than in most other

species of this genus. The insect is of a pale fulvous colour, with the disc of the

thorax more or less zeneous (in some specimens the entire head and thorax are of this

colour); the elytra have frequently the extreme sutural and lateral margins zneous.

20. Chrysodina (?) granulata.

Black, the basal joints of the antenne and the legs fulvous, above greenish-seneous ; head and thorax finely

granulate and sparingly punctured ; elytra very finely punctate-striate, the punctuation obsolete towards

the apex.

Length 1} line.

Head greenish, very minutely granulate and scarcely perceptibly punctured; the clypeus separated from the

face at the sides by a very fine groove, its lower edge angulate-emarginate, the surface punctured like the

rest of the head; labrum fulvous, its anterior margin piceous; palpi and the apices of the mandibles

fulvous; antenne two-thirds the length of the body, the lower six joints fulvous, the rest black, the

latter strongly thickened ; thorax transverse, scarcely narrowed in front, slightly widened at the middle,

the sides nearly straight behind, but slightly rounded anteriorly, the posterior angles produced into a

short point, the surface granulate like that of the head and nearly as finely (but more closely) punctured ;

scutellum broader than long; elytra moderately convex, parallel, minutely granulate, the punctuation fine

and somewhat serially arranged (distinct at the base, impressed in fine and scarcely perceptible strie

towards the apex), the interstices perfectly flat ; prosternum broader than long, punctured ; legs fulvous.

Hab. Mexico, Chilpancingo in Guerrero (Hége).

One specimen only of this small species was obtained. The antenne are propor-

tionately long, and the entire upper surface is finely granulate and finely punctured.

C. granulata differs from the allied forms in its elongate general shape and in the

transverse-subquadrate form of the thorax.

CHALCOPLACIS (p. 111).

8. Chalcoplacis fulvitarsis.

Broadly ovate, very convex, metallic green or blue, the antennsz and tarsi fulvous; head and thorax closely

punctured ; elytra punctate-striate.

Length 2 lines.

Head rather opaque, closely punctured throughout, the punctures on the vertex in the form of strige, the

clypeus bounded above by two raised metallic green spaces; antenne more than half the length of the

body, fulvous, the terminal joints slightly compressed; thorax three times as broad as long, the sides

nearly straight at the base, rapidly converging towards the apex from the middle, the anterior angles

produced beyond the eyes, the surface very closely impressed laterally with somewhat elongate punctures

(which are here and there confluent and extend quite to the lateral margin), the middle of the disc much

more remotely punctured ; elytra finely and regularly punctate-striate on the disc, a broader space near

the lateral margin impunctate, the epipleure nearly flat; underside and legs metallic green or blue, the

tarsi fulvous.

Hab. Panama, Volcan de Chiriqui (Champion).

A single specimen. The closely and somewhat rugosely-punctured head and the

fulvous tarsi distinguish C. fulvitarsis from any of its allies.

CHALCOPLACIS.—PHEDRA. 189

4, Chalcoplacis mexicanus.

Ovately rounded, black, above dark bluish or greenish, the antenne and legs fulvous; head and thorax

minutely granulate and finely punctured; elytra very closely punctate-striate.

Length 1-1} line.

Of moderately rounded and convex shape; the head in the male not perceptibly punctured, in the female

finely punctate, in both sexes minutely granulate ; the epistome not separated from the face, its anterior

edge moderately emarginate; mandibles large, partly fulvous ; antennx about half the length of the body,

subfiliform, entirely fulvous ; thorax nearly three times as broad as long, scarcely widened at the middle,

the sides rounded and slightly narrowed in front, the surface granulate like that of the head, and very

finely and rather distantly punctured, the punctures only visible under a strong lens; scutellum smooth,

scarcely broader than long ; elytra ovate, moderately convex, dark bluish, with closely approached rows

of fine punctures, which become rather more obsolete posteriorly ; underside nearly black, the breast with

a greenish gloss; legs dark fulvous, the apex of the posterior femora stained with piceous, .

Hab. Mexico, Acapulco in Guerrero (Hége).

Two specimens, apparently male and female, the former being at least one third

smaller than the latter, and the female having the punctuation of the thorax and elytra

very much more strongly marked; the shoulders are prominent, acute, and of a

metallic greenish colour; the prosternum in the smaller example (male?) is broader

than long, quadrate, and flat. In the strongly transverse thorax, its thickened flanks,

and the ovately rounded general shape, the insect agrees with Chalcoplacis.

PH.ZDRA (p. 111).

The generic name Phedra having already been used three times in zoology, it has

been changed by Lefévre [Cat. Eumolp. p. 166 (1885) ] to Phedrias.

This author, in his diagnosis of the genus, gives the femora as unarmed; in

P. maxima, Lefevre, however, they have a distinct tooth.

Phedra maxima (p. 112).

To the locality given, add :—Gvatemata, Coban in Vera Paz (Conradt).

8. Phedra chapuisi.

Above dull greenish, opaque, the antennm (the seventh and the apical two joints excepted), abdomen, and legs

fulvous ; head, thorax, and elytra minutely granulate and finely punctured ; breast piceous.

Length 13 line. .

Hab. Panama, Bugaba (Champion).

P. chapwisi seems to resemble P. rufipes, Chap., from Guiana, in coloration, so far as

I can judge from the short diagnosis given by that author; P. rufipes, however, is

described as “subnitida,” and with dark terminal joints to the antenne. In the

Panama insect the entire upper surface is opaque, and of a greenish-leaden colour; the

head has a few fine punctures (more numerous on the clypeus); the labrum and palpi,

as well as the antenne, are fulvous, the latter having the seventh and the apical two

joints fuscous; the thorax is more than three times as broad as long, rounded at the

sides (but without projecting anterior angles), and very finely and rather closely punc-

tured ; the scutellum is impunctate, minutely granulate, and narrowly margined with

blue; the elytra are very convex at the base, very finely and rather closely punctate-

striate, their epipleure broad and concave; the breast, cox, and extreme base of the

femora are piceous, the rest of the legs and the abdomen being fulvous. A single

specimen.

4. Phaedra abdominalis.

Dark violaceous-blue, the basal joints of the antennse and the abdomen obscure fulvous; thorax finely and not

closely (the sides more remotely) punctured ; elytra closely and more strongly (semi-regularly) punctate.

Length 23 lines.

Broadly rounded, very convex; the head shining, sparsely impressed with deep punctures ; the clypeus wedge-

shaped, sparingly punctured; labrum and mandibles piceous; antenne rather short, the lower three

joints obscure fulvous, the rest black ; thorax about three times as broad as long, the sides but moderately

rounded, the anterior angles rather obtuse and preceded by a short impressed line, the surface finely but

not closely punctured, the punctures at the sides more strongly impressed and still more remote from each

other; elytra much more strongly and closely punctured than the thorax, with a short semicircular row

of punctures extending from the shoulder to about the middle of the lateral margin, and a broad smooth

impunctate space within the margin, the inflexed limb deeply concave ; underside and legs blackish-blue ;

abdomen dark fulvous.

Hab. Panama, Volcan de Chiriqui (Champion).

This insect has the elytral epipleuree broad and deeply concave, as usual in Phedra,

from the other species of which it may be known by the sparingly-punctured head and

the colour of the abdomen. A single specimen.

5. Pheedra brevicornis.

Rotundate, convex, metallic purplish; above cupreous; antenne short, the basal joints flavous; thorax

strongly transverse, closely punctured; elytra rather remotely punctate-striate.

Length 2 lines.

Of a brilliant cupreous colour above, bluish-purple beneath ; the head strongly and closely punctured ; the

labrum and mandibles piceous; antenne extending only to the base of the elytra, the lower six joints

flavous, the others fuscous, the latter slightly thickened; thorax three times as broad as long, the sides

obliquely rounded and strongly narrowed in front, the anterior margin deeply concave-emarginate, the

surface strongly and closely punctured at the sides, more sparsely so on the disc; scutellum not broader

than long; elytra wider at the base than the thorax, rounded at the sides, regularly convex, the surface

rather remotely but not more finely punctured than the thorax, the punctures arranged in semi-regular

rows, the epipleure broad and nearly flat; prosternum subquadrate.

Hab. Nicaragua, Chontales (Janson).

This handsome species, of which only a single specimen was obtained, seems to

possess all the structura characters of Phedra; but is distinguished from the other

members of that genus by the comparatively very short antenne.

Lamprospherus apicalis (p. 112).

The Mexican specimen belongs to the fulvous variety, but does not otherwise differ

from the Guatemalan form.

1 (a). Lamprospherus submetallicus.

Fulvous, tinged with metallic green above, the seventh and the apical two joints of the antenne fuscous;

thorax finely and sparingly punctured ; elytra strongly punctate-striate, the interstices at the sides and at

the apex costate.

Length 14-14 line.

Head fulvous, the vertex greenish, exceedingly finely granulate, and with a few fine punctures, longitudinally

grooved in the centre; the clypeus trigonate, separated from the face by a transverse groove, its surface

sparingly but strongly punctured; antenna filiform, extending beyond the middle of the elytra, fulvous,

the seventh and the apical two joints fuscous; thorax nearly three times as broad as long, the sides

moderately rounded and narrowed towards the apex, with a narrow margin, the surface remotely, irre-

gularly, and finely punctured; elytra with a scarcely perceptible depression below the base, very strongly

and regularly punctured, the punctures at the sides still coarser, the interstices at the sides and at the

apex strongly costate; underside and legs fulvous.

Hab. Panama, Volcan de Chiriqui, David, Caldera (Champion).

L. submetallicus may be known from the fulvous varieties of L. apicalis by the

metallic gloss of the upper surface, the scarcely punctured head, and the colour of the

antenne. .

Although M. Lefévre himself has kindly examined our Panama specimens, I have

some doubt as to the correctness of his determination. The Panama insect is smaller

than South-American examples of Z. cwruleatus; the thorax is nearly black and more

finely punctured; and the general shape is more pointed. It is possible, however, that

these differences are only due to local variation. Some of the Panama specimens have

entirely black elytra.

1 (c). Lamprospherus variabilis. |

Below piceous or black, above metallic green or violaceo-cupresws § the head strongly; the thorax ferhotely, the

elytra strongly and closely, punctured ; antenne and legs fulvous.

Length 13 line.

Head cupreous, remotely and coarsely punctured, with an obsolete longitudinal groove in the centre; the

clypeus as strongly punctured as the rest of the head; labrum and antenne fulvous, the third and fourth

joints of the latter equal; thorax more finely punctured than the head, the punctures rather remote, the

punctate-striate, the punctures distinct to the apex, and with a deeply impressed sutural stria.

Hab. Guatemata, Cerro Zunil (Champion).

Two examples. JI am obliged to separate this insect from L. ewruleatus, owing to

the strong punctuation of the head and elytra, and the cupreous colour of the thorax.

The elytra in one specimen are violaceous (almost black) in colour; in the other they

are metallic green; in L. cwruleatus the punctuation is almost obsolete near the apex.

Lamprospherus minutus (p. 113).

To the localities given, add:—Panama, Bugaba, Caldera, Tolé (Champion).

Var. Above brownish-seneous or dark blue.

This small species seems to be very variable in colour, the specimens from Guate-

mala being generally bright metallic green, those from Bugaba dark metallic blue, and

those from Tolé brownish-zneous; there is also a slight difference in shape, some

examples being rounded, others more pointed at theapex. The filiform (not thickened)

antennee and the more transverse thorax distinguish it from Chrysodina pusilla, an

insect found at the same locality. LZ. minutus is the smallest known member of the

genus,

8. Lamprospherus semipurpureus.

Subrotundate, very convex, black, above obscure dark purplish ; the basal joints of the antenne fulvous ; the

head and thorax finely punctured; elytra remotely and rather finely punctured, the punctures coarser

towards the base.

Length 3-1 line.

Head with a few fine punctures on the vertex, the lower portion and the clypeus more strongly punctured, and

with a deep longitudinal groove down the centre, not extending to the vertex ; labrum fulvous; antenne

about half the length of the body, the lower four joints fulvous, the rest black; thorax of usual shape,

dull purplish, the surface impressed with not very closely-placed somewhat elongate punctures; elytra

purplish-violaceous, rather strongly punctured anteriorly, more finely so towards the apex ; underside and

legs black, the anterior tarsi and the knees more or less fulvous.

Hab. Panama, Volcan de Chiriqui (Champion).

The dark purplish colour and the black legs separate this small species from its

allies, Z. janthinus and LL. luctuosus, Lefévre ; it differs from the former in the colour

of the legs and in the rugosely punctured head, and from the latter in the purplish

colour of the legs and upperside.

4, Lamprospherus plumbeus.

Bluish-black, the labrum, antennz, and legs fulvous; head and thorax opaque, finely punctured and granulate;

elytra strongly and closely punctate-striate.

Head broad, minutely granulate, and scarcely perceptibly punctured, the upper portion entirely impunctate ;

labrum broad, fulvous; antenne more than half the length of the body, fulvous, the terminal joints

slightly thickened; thorax at least three times as broad as long, nearly equal in width, the sides very

moderately rounded and but slightly narrowed in front, the surface very minutely punctured, the punctures

more distinct at the middle than at the sides, the interspaces very finely granulate, opaque; elytra more

shining, dark blue, closely and strongly punctate-striate ; legs fulvous.

Hab. Mexico, Acapulco in Guerrero (ége).

A single specimen. The opaque and minutely punctured thorax and the fulvous

antenne and legs characterize this species.

NODA (p. 113).

I cannot help expressing here my regret that in Moda, as well as in so many other

difficult genera, short diagnoses should have been published of extremely closely allied

species, which makes their determination impossible without an examination of the

types ; moreover, there are some species almost intermediate between this genus and

Chrysodina, either in the structure of the antenne or in the form of the thorax. In

his general diagnosis of the group Iphimeine, into which Noda enters, M. Lefévre

gives the anterior femora as armed with a tooth; but this applies only to some of the

genera in this group and certainly not to Noda.

The name Noda being preoccupied in Diptera, it has been changed by M. Lefévre

[Cat. Eumolp. p. 166 (1885)] to Nodonota.

Noda cretifera (p. 114).

To the localities given, add :—MExico, Omilteme and Chilpancingo in Guerrero,

Cuernavaca (H. H. Smith), Michoacan (Flohr); GuateMata, Cubilguitz, Zapote, Dueiias

(Champion).

N. cretifera seems to be subject to great variation, and the male insect is conse-

quently often very difficult to recognize, as it has not the distinguishing curved elytral

costa of the female. The punctuation of the elytra is always very fine, and arranged in

more or less double rows; while that of the thorax is variable, though usually very

fine and close. The elytra of the male insect have a more or less smooth space below

the shoulders, corresponding to the place occupied by the raised costa of the female.

The general colour of the upper surface varies from blue to green and violaceous; and

the tibise, or the entire legs, are as frequently fulvous as they are violaceous. Specimens

from Juquila, Omilteme, and Chilpancingo are smaller, more robust, and more convex

than those from the other localities.

Oblong-ovate, narrowed posteriorly, eneous, the base of the antenne fulvous ; thorax very closely punctured ;

elytra closely and strongly geminate-punctate-striate, the interstices minutely punctured and slightly

costate at the sides.

Length 12 line.

Q. Head irregularly but rather closely punctured, the labrum and palpi piceous; antennae short, scarcely

extending beyond the base of the thorax, the basal and the five terminal joints piceous, the others fulvous ;

thorax rather more than twice as broad as long, the sides very slightly rounded, the anterior angles acute,

the surface closely and distinctly punctured, the sides more closely than the disc ; elytra with deep and

closely-placed double rows of punctures, the interstices convex at the sides ; underside and legs seneous,

the underside finely granulate and punctured.

Hab. Mexico, Durango city (Hége).

In the strongly and closely geminate-punctate-striate elytra this insect resembles

N. lateralis, from which it differs, however, in having the lateral interstices only

slightly raised (these in W. lateralis being replaced by highly raised ridges). A

single male specimen, also obtained at Durango, agrees in colour with the females _

from which our description is taken, and may be the other sex of the same species; it

has the thorax more convex and more strongly rounded at the sides; the elytra,

however, are quite differently punctured, the punctuation being fine and arranged in

closely approached single rows. The general colour may be described as obscure

cupreous or bronze.

Noda lefevrei (p. 117).

To the localities given, add :—Mexico, Vera Cruz, Orizaba (Sallé), Atoyac, Teapa

and Frontera in Tabasco (H. H. Smith); Guatemata, Sabo, Tamahu, El Jicaro, Purula,

and San Gerénimo, all in Vera Paz (Champion), Aceytuno (Salvin).

N. lefevrei is evidently subject, like most of its congeners, to great variation ; and I

refer all the specimens which show distinctly raised or costate elytral interstices at the

apex, and which have the extremities of the tibie more or less fulvous, to this species.

In the Sallé collection, WV. lefevret bears the name of NV. apicecostatis.

The present insect cannot be mistaken for WN. lateralis, Jac., which has also the

elytra costate at the apex, owing to the thorax being rounded at the sides (in WV. late-

ralis the sides are nearly straight). In both sexes of WV. lefevrei the elytra are without

tubercles, the female thus differing from that of NV. lateralis.

Mr. Smith obtained numerous specimens at Teapa.

NODA. 195

Very closely allied to, and perhaps only a local variety of, WV. lefevrei ; the numerous

specimens, however, before me agree in having the tibie entirely fulvous and the thorax

opaque. The general colour of the upper surface varies from light or dark neous to

metallic blue; the head is finely punctured on the vertex, much more strongly so

between the eyes; the antenne have the second to the sixth or the second to the

seventh joints fulvous, the first one above and the terminal joints fuscous or bluish-

black; the thorax is nearly always of a duller colour than the elytra, and its sides are

strongly narrowed anteriorly; the surface is usually much more finely and sparingly

punctured than in N. lefevrei (the punctuation sometimes almost obsolete); the disc of

the elytra is generally finely geminate-punctate-striate, the sides much more strongly

punctured in single rows, and the interstices at the apex are strongly costate; the legs

are eneous, the tibie entirely fulvous. The female insect, although more strongly

punctured than the male, does not differ materially in other respects. The Teapa

specimens may represent yet another closely-allied species: they differ in having the

thorax and elytra more shining and more strongly punctured, and in the base of each

of the apical joints of the antenne being fulvous; the tibie agree, however, in colour

with those of the specimens from Tapachula (I have not seen a single specimen of

N. lefevre thus coloured, the fulvous tint being always confined to the extreme apex

of the tibiz). .

It may be remarked that one of the localities for WV. opacicollis is on the Pacific, the

other on the Atlantic slope.

9 (s). Noda chontalensis.

Var. Legs obscure fulvous.

Length 13-1? line.

Hab. Nicaracva, Chontales (Janson).

Of rather convex and subcylindrical shape, dark blue or metallic cupreous; the

thorax but little rounded at the sides, its surface not very closely nor very finely

punctured ; the elytra a little more strongly and rather closely punctate-striate, the

arrangement in double rows only here and there perceptible, the interstices smooth.

N. chontalensis, of which the sexes scarcely vary except in size, is more finely punctured

than NV. lefevrei, from which it also may be known by the elytra having the interstices

smooth near the apex in both sexes. In N. viridis the thorax is almost rugosely punc-

tured; in WV. subdcylindrica the thorax is also quite differently sculptured, and the

elytra are strongly punctate-striate; in WV. fulvicornis the thorax is proportionately

longer, and the antenne and legs are fulvous.

Head minutely granulate, rather strongly and closely punctured, a triangular space above the insertion of the

antenne shining and smooth; mandibles and the terminal joints of the palpi piceous; antenne nearly

two-thirds the length of the body, the basal two or more joints (sometimes as many as the basal six)

fulvous (the first stained with piceous above), the rest black; thorax transverse, more than twice as

broad as long, the anterior margin perfectly straight, the posterior margin produced at the middle, the sides

rounded, concave near the base, the posterior angles pointed and produced, the surface finely, irregularly,

and not very closely punctured, the interspaces minutely granulate; scutellum smooth; elytra convex,

without basal depression, rather evenly and finely punctate-striate, the punctures distinct to the apex and

stronger at the sides than on the disc, the interstices flat ; underside and legs greenish-seneous.

Hab. Mexico, Chilpancingo in Guerrero, Huetamo in Michoacan (f6ge).

Closely allied to, but apparently distinct from, WV. chontalensis, from which it chiefly

differs in having the sides of the thorax sinuate or concave near the base (instead of

simply rounded) and the posterior angles acutely pointed, and the head more strongly

punctured. The antenne are comparatively elongate; the colour of the basal joints

is variable. The female only differs from the male in the stronger elytral punctuation

and in the raised submarginal interstices.

Elongate, subcylindrical, blackish-zeneous, above dark blue (3) or violaceous (9); antenne and legs fulvous ;

elytra strongly and closely punctate-striate, with a slight transverse depression below the base.

$. Thorax remotely and finely punctured.

@. Thorax more transverse, more closely punctured ; the elytra broader, the lateral interstices obsoletely

costate.

Length 13-14 line.

3. Of unusually elongate shape, metallic dark blue above; the head without central groove, rather irregularly

but distinctly punctured; the labrum, palpi, and antenne fulvous, the terminal joints of the latter

slightly darker; thorax about twice as broad as long, the sides evenly rounded and moderately narrowed

in front, the anterior angles not produced, the surface finely, very remotely, and irregularly punctured ;

scutellum slightly broader than long; elytra convex and nearly parallel, scarcely perceptibly depressed

below the base, the punctures strong and arranged in close rows, the submarginal row very regular and

even; legs fulvous.

Hab. Mexico (Sallé).

There are two specimens of this insect, marked ¢ and 9, and named W. inconstans,

in the Sallé collection. The fulvous antenne, less transverse and more remotely punc-

tured thorax, the entirely fulvous legs, and more elongate general shape (especially of

the male) separate NV. elongata from N. chontalensis. In the female of the present

species the elytral depression is a little more distinct than in the other sex.

Noda violaceipennis (p. 118).

To the localities given, add :—Mextco, Oaxaca (Sallé), Juquila (Flohr).

Mexican specimens differ from those from Guatemala in having the thorax rather

less transverse and less rounded at the sides, the elytral punctuation somewhat finer

and more remotely placed, and the upper surface of a more decided dark blue colour.

Mr. Flohr has kindly sent me examples of both sexes. ‘The female was hitherto

unknown to me; it differs from the male in the costate lateral interstices of the elytra,

and in its more pointed shape and rather stronger punctuation.

14 (a). Noda fulvicornis.

Subcylindrical, convex, eneous, dark metallic blue or greenish-blue; the antenne and legs fulvous; thorax

transversely convex, very finely and closely punctured ; elytra rather closely punctate-striate, the punc-

tures coarser than those of the thorax.

Length 1 line.

Of rather parallel, convex, and cylindrical shape; the head finely but irregularly punctured (but variable in

this respect) ; labrum and palpi fulvous, the last joint of the latter comparatively robust ; antenne entirely

fulvous, or with the terminal joints slightly darker; thorax transverse, still more convex than in the

allied forms, the sides rounded, the surface very closely and finely punctured; scutellum slightly broader

than long, its sides rounded; elytra parallel, rather regularly punctate-striate, the punctures gradually

becoming finer towards the apex and arranged in close and slightly geminate rows; legs fulvous, robust,

the femora in some specimens darker.

Hab. Mexico, Oaxaca, Cordova, Capulalpam (Sal/é).

Very closely allied to WV. balyi, but differing in the dark blue colour of the upper

surface; the thorax is also longer, less rounded at the sides, more narrowed in front,

and more finely and more closely punctured (the punctures equal in size, this not

being the case in NW. balyi). N. balyi is also larger, and of an eneous or obscure

cupreous colour.

Noda curtula (p. 120).

To the Mexican localities given, add :—Presidio, Tres Marias Is. (Forrer), Amula,

Chilpancingo, and Tepetlapa, all in Guerrero (H. H. Smith), Tacambaro in Michoacan,

Matamoros Izucar in Puebla (Hoge).

Numerous examples since received from the above localities prove that N. curtula,

like so many of its congeners, is a very variable species, not only in colour but in

shape, some specimens being broadly ovate, others more oblong and less rounded ; the

punctuation of the elytra is close and distinct (but often very fine near the suture), that

of the female much coarser, the interstices at the sides in this sex being costate; the

thorax is very finely punctured on the disc, extremely closely so at the sides.

N. curtula somewhat resembles Chrysodina cupriceps in shape, but, in my opinion,

is better placed in Noda.

18 (a). Noda basalis.

Broadly ovate, dark brownish-eneous, the basal joints of the antenne fulvous; thorax finely and closely

punctured at the sides, more remotely so on the disc; elytra irregularly geminate-punctate-striate, and

laterally with three or four short costz at the base.

Length 2 lines.

198 PHYTOPHAGA.—SUPPLEMENT.

¢. Head moderately closely and finely punctured, with an obsolete depression between the eyes, the latter

sinuate at the inner margin; epistome not separated from the face, a little more strongly punctured than

the head; labrum piceous; antenne scarcely extending to the middle of the elytra, the lower eight joints

fulvous, the terminal ones nearly black, the latter thickened ; thorax strongly transverse, but moderately

‘narrowed anteriorly, the sides very little rounded, the anterior angles produced into a short straight

point, the surface very finely and closely punctured at the sides, more remotely so on the disc; scutellum

much broader than long, impunctate ; elytra broadly ovate, scarcely narrowed posteriorly, with a short

depression below the base, the punctuation fine and arranged in irregular double rows, which are inter-

rupted near the shoulders and at the sides by four or five short coste (these extending as far as the basal

depression, the outer one, however, accompanying the lateral margin throughout), the apical portion im-

pressed near the suture with a deep stria, the extreme apex rather pointed ; the tibiee are generally more

or less fulvous at the apex; the prosternum is distinctly longer than broad and constricted at the middle,

Hab. Mexico, Ventanas in Durango, Presidio (forrer).

Like WV. curtula, the present species is broadly ovate (instead of having the more

oblong shape of a typical Noda); it agrees, however, with Moda in the form of the

antenne, scutellum, and prosternum. WW. basalis, of which apparently only female

specimens were obtained, may be distinguished from NV. curtula by the short longitu-

dinal coste at the base of the elytra and by the less crowded punctuation at the sides

of the thorax.

22. Noda placida.

Metallic greenish-blue, the basal joints of the antenne and the legs fulvous; thorax short, extremely finely

and rather remotely punctured; elytra with a shallow transverse basal depression, closely and rather

strongly punctate-striate.

@. Above brownish-cupreous ; elytra with a deeper basal depression, and with three or four longitudinal

cost at the sides.

Length 14-13 line.

Hab. Mextco, Cordova, Jacale (Sallé), Zacnaltipan in Hidalgo (Hoge) ; PANAMA,

Volcan de Chiriqui (Champion).

Of this species a male and a female specimen from Cordova (taken “in copula ”), as

well as two others from Jacale, are contained in the Sallé collection. NH. placida seems

to me to differ from most other species from our region in the well-marked basal

depression of the elytra in connection with the very fine punctuation of the thorax,

the closely-punctured elytra, and the fulvous legs. In the female the elytral depression

is deeper, but the punctuation is much finer and somewhat arranged in double rows.

In the male the thorax is short, strongly transverse, and rather strongly rounded at the

sides, the anterior angles being produced into a short outwardly-directed point.

The specimens from Zacualtipan agree entirely with the others, as well as those

obtained by Mr. Champion in Chiriqui.

23. Noda metallica.

Pale metallic green; antenna black; the basal five joints fulvous; thorax strongly transverse, finely and

rather closely punctured ; elytra finely subgeminate-punctate-striate ; legs obscure cupreous.

NODA. — 199

Q. Elytra with the two submarginal interstices costate.

Length 13-12 line.

Moderately convex, of a metallic-green colour, slightly tinged with yellowish; the head distinctly but irregu-

larly punctured ; the labrum and mandibles piceous; antenne half the length of the body, fulvous, the

terminal six joints bluish-black; thorax nearly three times as broad as long, the sides moderately and

evenly rounded, the anterior margin straight, the anterior angles not produced but acute, the surface

finely punctured, the punctures a little more closely placed at the sides than on the disc, the inter-

spaces here and there impressed with very minute punctures and finely granulate; elytra scarcely more

strongly punctured than the thorax, the punctures arranged in regular but somewhat geminate rows

(more distinctly geminate in the female), which near the apex form single strie ; legs entirely dark

cupreous or geneous.

Hab. Mexico, near the city (Flohr), Guanajuato, Orizaba (Sallé), Chilpancingo in

Guerrero (Hoge). |

Although not greatly differing from several other species of this genus, V. metallica

may be known by its pale greenish colour, the fine punctuation of the thorax and

elytra, and the semi-cupreous legs; the sexes are very similar in sculpture. NW. creti-

fera, Lefévre, has the apices of the tibie fulvous, and the elytra in the female

differently sculptured ; WV. subcylindrica, Jac., is of a more convex shape, and has the

thorax and elytra much more closely punctured. The coste at the sides of the elytra

in the female of WV. metallica are not very strongly raised but distinct.

24. Noda plumbea.

Dark leaden-blue; the head and thorax very finely and sparingly punctured; elytra convex, finely and regu-

larly punctured.

2. Slightly larger, the thorax more transversely shaped, the elytra similar to that of the male.

Length 13-14 line.

Of convex, somewhat posteriorly narrowed shape; the head broad, sparingly punctured, the epistome not

separated from the face; antenne half the length of the body, proportionately slender, the lower five

joints fulyous (the first stained with dark blue above), the others bluish-black ; thorax twice as broad as

long in the male, narrowed in front, the sides moderately rounded, the surface very finely and remotely

punctured, almost impunctate at the sides; scutellum scarcely broader than long, smooth; elytra convex,

very little narrowed posteriorly, not depressed below the base, the punctures fine, rather widely separated,

and placed at regular distances in rows, which are distinct to the apex; underside coloured as above ;

the prosternum constricted between the coxe.

Hab. Mexico, Teapa (H. H. Smith).

The uniform and rather dull leaden-blue colour, the sparingly punctured thorax, and

the regularly punctured elytra distinguish WV. plumbea from its allies. The female is

very similar to the male, except that it has the thorax more transversely shaped.

Several specimens.

25. Noda parvula.

Violaceous-black, the antenne and tibie fulvous; thorax scarcely perceptibly punctured ; elytra finely punc-

tate-striate on the disc, more strongly so at the sides, the base with an obscure depression.

Length 1 line.

Head strongly but not very closely punctured ; the epistome wedge-shaped, the anterior margin deeply con-

cave-emarginate; labrum and palpi fulvous; antenne half the length of the body, entirely fulvous;

200 PHYTOPHAGA.—SUPPLEMENT.

thorax about twice as broad as long, narrowed in front, the sides but slightly rounded, the surface minutely

granulate, opaque, with remotely-placed extremely fine punctures (only visible under a strong lens) ;

scutellum broader than long; elytra with regular rows of fine and rather closely placed punctures, the

shoulders prominent but narrow, the base with a very obsolete depression, the punctures at the sides

much stronger than those on the disc ; femora dark wneous, the tibie entirely (or partly) fulvous.

Hab. Panama, Bugaba, David, San Lorenzo (Champion).

The small size, the dark opaque violaceous colour, and the almost impunctate thorax

separate WV. parvula from its many congeners. A specimen from Bugaba, which I take

to be the female of the same species, has an elongate tubercle placed parallel with and

close to the shoulder and a transversely-shaped similar tubercle below it; in this

example the terminal joints of the antenne and the tibie are dark.

26. Noda cyanella.

Oblong, pointed posteriorly, obscure eneous; above dark blue; the antenne and legs fulvous; thorax trans-

verse, short, closely punctured; elytra very closely and rather irregularly punctured, the interstices at

the apex subcostate.

Length 1? line.

6. Head strongly and rather closely punctured; the mandibles piceous ; the palpi fulvous, their terminal

joint very elongate and subcylindrical ; antenne extending to the middle of the elytra, entirely fulvous ;

thorax short, transverse, more than twice as broad as long, the sides evenly rounded, the anterior angles

slightly produced, the surface extremely finely granulate and closely impressed with punctures of unequal

size, the punctures more crowded at the sides than on the disc, the interspaces also here and there minutely

- punctate; scutellum broader than long, its disc impressed with a few minute punctures; elytra very

closely punctured, the punctuation stronger than that of the thorax, with a narrow smooth longitudinal

space near the suture, the interstices towards the apex slightly costate, those at the sides somewhat rugose ;

legs entirely fulvous.

Hab. Mexico, Oaxaca (Sallé).

NN. cyanella, of which only a single male specimen is before me, may be known by

the very close and almost rugose punctuation of the thorax and elytra, the punctures

on the latter scarcely arranged in rows; the fulvous antenne and legs will further

assist in the recognition of the species.

27. Noda acutangula.

Blackish-ezneous, above metallic green or bluish; antenne and legs fulvous; head and thorax closely punc-

tured, the anterior angles of the latter dentiform ; elytra strongly and closely punctate-striate.

Length 1? line.

Of rather broad, posteriorly pointed shape ; head strongly and rather closely, the vertex more finely, punctured ;

antenne extending nearly to the middle of the elytra, entirely fulvous, the terminal joints much thickened ;

thorax rather strongly transverse, the sides evenly rounded, narrowed anteriorly, the angles produced into

a short but distinct acute point or tooth, the surface rather closely impressed with punctures of unequal

size; scutellum broader than long, with a few fine punctures; elytra more coarsely punctured than the

thorax, the punctures arranged in close and rather regular rows; legs fulvous or rufous.

Hab. Mexico, Silao (Sallé), Zacualtipan in Hidalgo (Hége).

Of this species (which may be distinguished from most others from our region with

fulvous antenne and legs by the produced angles of the thorax) three specimens are

NODA. 201

contained in the Sallé collection; two of these are metallic green above, and one is

nearly black. The three others obtained by Herr Hoge are bluish-green.

28. Noda hondurensis.

Oblong-ovate, metallic green, the antenne and legs fulvous; thorax closely and irregularly punctured, the

interspaces very finely granulate, the anterior angles produced ; elytra rather irregularly punctate-striate,

the strive almost equidistant from each other, the interstices minutely granulate.

@. Elytra with three or four lateral coste and a small tubercle.

Length 13-2 lines.

Head minutely granulate, rather closely and distinctly punctured, longitudinally depressed between the eyes ;

anterior margin of the epistome but moderately emarginate; mandibles piceous; antenne entirely

fulvous; thorax strongly transverse, more than twice as broad as long, the sides strongly rounded, the

anterior angles produced outwardly into a small tooth, the surface closely but rather regularly impressed

with punctures of unequal size, the interspaces very finely granulate; scutellum with its sides oblique, the

apex pointed, its surface slightly concave or depressed ; elytra moderately convex, more strongly punc-

tured than the thorax, the punctures arranged in close but not very regular rows, the interstices flat and

minutely granulate ; legs robust, entirely reddish-fulvous; prosternum longer than broad, constricted at

the middle, and clothed with rather long yellow pubescence.

Hab. British Honpuras, R. Sarstoon (Blancaneaux).

_ The principal characters by which this species may be recognized are the transversely-

shaped thorax and its acutely produced anterior angles in connection with the fulvous

antenne and legs and the finely granulate upper surface. The female has the frontal

groove between the eyes more deeply impressed, and the elytra furnished with three

or four more or less distinct coste at the sides, the innermost of which is interrupted

and preceded before the middle by a small tubercle, the base in front of this tubercle

being somewhat transversely depressed. Some specimens are of a very obscure

brownish-eneous colour, but this is probably due to immaturity.

N. hondurensis is very closely allied to NV. acutangula; the latter, however, has the

head, thorax, and elytra still more closely punctured, the elytra with the punctures

much less distinctly arranged in rows and the interstices not granulate.

29. Noda obliterata.

Blackish-green, above metallic blue, greenish, or cupreous ; antenne and legs fulvous ; thorax finely and closely

punctured ; elytra very finely punctured at the base, the punctures nearly obsolete below the middle.

.Q. Of a darker cupreous tint, the antenne and legs sometimes infuscate, the elytral interstices at the sides

slightly convex. .

Length 14-13 line.

Generally of a bright pale cupreous or green colour, with entirely fulvous antenne and legs; the head distinctly

but not very closely punctured; the antenne about two-thirds the length of the body, the terminal joints

strongly thickened ; thorax twice as broad as long, narrowed in front, the sides distinctly rounded, the

anterior angles produced into a small tooth, the surface closely and irregularly punctured, the punctures

of unequal size; scutellum with a few fine punctures ; elytra convex, subcylindrical, with a shallow

depression below the base, the shoulders prominent, the punctuation very fine (but well marked in the

female), arranged in single not very closely approached rows, and almost obsolete below the middle.

elytra (the base of which is depressed), in connection with the fulvous antenne and

legs, distinguish 1. obliterata from its allies. The female varies in regard to the

colour of the legs and is more strongly punctured; but is not distinguished by strongly

marked elytral coste, the interstices being only slightly convex at the sides. |

A somewhat doubtful species.

30. Noda ovata.

Ovate, obscure eneous, the antenne and legs fulvous ; thorax transverse, the sides rounded, the surface finely

and closely punctured ; elytra more or less widened at the middle, the apex pointed, the disc very closely

punctate-striate.

Q. Elytra more elongate, less widened, the rows of punctures separated by narrow smooth longitudinal

spaces, the sides with about six tubercles, which are placed longitudinally in two rows.

Length 14-2 lines.

Hab. Panama, Pefia Blanca, Tolé (Champion).

NV. ovata may be at once separated from its allies by its ovate, posteriorly pointed

shape, the dull brownish-eneous colour, the fulvous antenne and legs, the transversely

shaped thorax (the sides of which are rounded), and the very closely punctured elytra.

The head is somewhat remotely punctured ; the labrum and the robust mandibles are

fulvous ; the antenne barely extend to the middle of the elytra, and are rather stout ;

the thorax is scarcely narrowed anteriorly, and its anterior angles are subtuberculiform

and furnished each with a single hair; the elytra have the shoulders rounded (scarcely

prominent), and are devoid of any post-basal depression. The female differs considerably

from the male in the sculpture of the elytra ; and has, in addition to the six more or

less elongate tubercles at the sides, a strongly raised costa placed parallel with the

lateral margin, all the other interstices being also more or less convex.

It is possible that WV. ovata may be better placed in Lefévre’s genus Hphyrwa (Ann.

Soc. Ent. Fr. 1889, p. 832), the thorax being very strongly transverse. Many species

of Noda, however, vary greatly in the form of the thorax (and also in having more or

less filiform antenne), and this seems to me to be an inconstant character.

31. Noda bella.

Greenish-black; above metallic yellowish-green, golden-yellow, or pale cupreous; the base of the antenne

fulvous ; thorax transversely convex, very closely punctured ; elytra very closely geminate-punctate-striate.

_Q. Larger, more pointed posteriorly, the legs fulvous.

Length 13-2 lines.

Hab. Mexico, Juquila (Sallé, Flohr).

Of rather convex, subcylindrical, and somewhat posteriorly narrowed shape, and

bright golden-yellow or yellowish-green colour; the head, thorax, and elytra very

closely but not very finely punctured ; the elytra with an obsolete depression below the

shoulders, the punctuation arranged in closely approached double rows which towards

the apex become single (as is generally the case in this genus), and the interstices

-NODA.—SPINTHEROPHYTA. 203°

shining and not granulate. The specimens which I consider to be the females of the

same species are larger, more pointed posteriorly, and have the legs fulvous and the

elytra entirely devoid of lateral coste (this character separating the female of WV. bella

from that of most other species of the genus).

The bright golden-yellow colour, the rounded sides of the thorax, and the crowded

punctures of the upper surface will help to distinguish the male, of which a single

example has been kindly given me by Mr. Flohr.

32. Noda congregata.

Oblong-ovate, black ; above metallic dark blue, the basal joints of the antenne fulvous; thorax transverse,

its surface crowded with oblong punctures ; elytra closely and finely punctate-striate.

Length 14 line.

Head finely and remotely punctured ; the anterior edge of the clypeus but slightly concave-emarginate ; labrum

and mandibles nearly black ; antenne less than half the length of the body, black, the lower three joints

fulvous, the terminal ones gradually thickened ; thorax twice as broad as long, the anterior lateral portion

rather strongly deflexed, the sides much rounded, the anterior angles slightly produced, the posterior

angles simple, the anterior and posterior margins somewhat produced at the middle, the entire surface

very closely covered with oblong punctures, the punctures equal in size throughout; scutellum smooth ;

elytra rather broadly ovate and convex, the shoulders prominent, the disc impressed with very regular

and rather close rows of fine somewhat distantly placed punctures; underside and legs black; tarsi

piceous ; prosternum strongly narrowed between the coxex.

~ Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith).

A very distinct species, of which only a single specimen (apparently a female) was

obtained. The crowded punctuation of the thorax, its anteriorly deflexed shape, and

the black underside and legs, are the chief characters of V. congregata.

The sexes of this species seem to differ somewhat in the strength of the punctuation

of the thorax; in some specimens the tibie are almost entirely fulvous, but this colour is

restricted in the type of S. cyanea, Lefévre, to the base of the femora. The insect is of

a dark blue colour, the thorax being more opaque, and closely and strongly punctured.

The name thoracica has three years’ priority over that of cyaned ; the species is rightly

included in Spintherophyta by Lefévre.

Head not longer than broad, minutely granulate and opaque; eyes notched ; labrum fulvous ; mandibles very

robust and prominent, obscure fulvous; palpi flavous, the terminal joint piceous, elongate, and cylindrical ;

antenne not extending much beyond the base of the elytra, pale fulvous, the terminal joints moderately

and gradually thickened; thorax transverse, more than twice as broad as long, the sides rounded and

remotely and finely punctured, the punctures only visible under a strong lens; elytra short and broad,

more shining than the thorax, rather strongly and closely punctured, the punctures arranged in irregular

rows, the interstices near the lateral margin convex; underside and legs black, the latter robust, the apex

The species of this genus described below agrees well in its structural characters with

the type, which is from the Amazon region. Ischyrolampra is allied to Spintherophyta,

but differs from it in the dilated terminal joints of the antenne.

1. Ischyrolampra panamensis. (Tab. XL. fig. 12, 3.)

finely punctured in rows, the interstices at the apex subcostate.

¢. Antenne with the terminal six joints strongly dilated.

¢. Antenne much less strongly dilated ; elytra longitudinally costate at the sides.

Length 14 line.

Head broad, the eyes widely separated and entire, the vertex finely and rather closely punctured, the interspaces

extremely minutely granulate, the surface pale fulvous with a more or less strong metallic green gloss ;

the clypeus transverse, its lower edge moderately concave ; labrum and palpi fulvous, the terminal joint

of the latter fuscous, rather elongate, subcylindrical ; antennee fulvous, the apical joints fuscous, the sixth

to the eleventh joints gradually and strongly dilated, the apical one more elongate, emarginate near the

apex ; thorax transverse, the sides nearly straight and narrowly margined, the anterior margin sinuate

behind the eyes, the posterior angles acute and pointed, the surface transversely convex, finely punctured,

of a pale metallic greenish colour much suffused with fulvous ; scutellum smooth ; elytra slightly widened

towards the apex, subcylindrical, scarcely more strongly punctured than the thorax (except at the sides),

the punctures arranged in rather close rows which show a tendency to form pairs, the interstices near the

lateral margin and at the apex costate; underside and legs fulvous, the latter robust, the femora very

strongly inerassate, the first joint of the posterior tarsi longer than the following one; claws appendiculate ;

prosternum narrowed between the coxe, its lower margin slightly concave.

Hab. Panama, Tolé, Pefia Blanca (Champion).

The ground-colour of this insect is pale fulvous, but the entire upper surface has a

AGBALUS (p. 123).

The type of this genus (A. sericeus) has short, robust antenne and legs, but several

of the species placed in it by Lefévre (including A. chalybeus) possess long, filiform

antennee and slender legs. |

Many examples of A. chalybeus were obtained by Mr. Champion; it is evidently a

very variable insect. The typical form, specimens of which from Panama M. Lefévre

has kindly examined, is of a dark blue colour above; the punctuation of the thorax is

fine, and that of the elytra strong and arranged in close rows. Other specimens, also

from the State of Panama, are much more finely punctured, and have the thorax more

rounded at the sides, and the antenne pale; some of these have dark fulvous legs.

Besides these varieties, two others are before me, one of them of a greenish-eneous or

bronze colour, the other metallic cupreous, the legs being either neous or fulvous. I

am unable to satisfactorily separate these forms, although they differ a little in shape

and punctuation, as well as in size and colour. The males of all of them have the usual

characteristic long spine to the posterior tibie.

4, Agbalus puncticollis.

Broadly ovate, black; above dark violaceous; the basal joints of the antenne fulvous; thorax closely and

evenly punctured, the punctures elongate in shape; elytra irregularly and closely punetate-striate.

Length 13 line.

Head very sparingly punctured, the labrum and mandibles black ; antenn two-thirds the length of the body,

black, the lower four joints fulvous, the terminal five joints thickened; thorax transversely convex, twice

as broad as long, the anterior portion deflexed, the anterior angles produced, the surface closely impressed

with very evenly distributed, deep, elongate punctures; elytra convex, rather short, closely and compara-

tively strongly punctate-striate, the shoulders prominent ; prosternum slightly narrowed at the middle.

Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith).

A single specimen. A. puncticollis seems to possess the structural characters of

Agbalus, although the tibie in the (apparently male) specimen obtained are unarmed;

the crowded and elongate punctures of the thorax will help to distinguish the

species.

5. Agbalus hogei.

Oblong-ovate, bluish-black ; above obscure purplish or violaceous; antenns and legs fulvous; thorax very finely

and closely punctured ; elytra strongly and closely punctate-striate, with an obsolete basal depression.

Length 14 line. .

Of rather short and broadly ovate shape; the head with some oblong and not very closely placed punctures on ©

the vertex, and an obscure median longitudinal groove; the clypeus rugosely punctured, bounded above

on each side by a smooth bluish space; labrum and palpi fulvous; antenne extending beyond the middle

of the. elytra, fulvous, the terminal joints slightly thickened and marked with fuscous at the apex ; thorax

transverse, convex, the sides strongly rounded and narrowed towards the apex, with a narrow reflexed

margin, the anterior angles acute but not produced, the surface very closely and finely punctured at the

sides, more remotely so on the disc; elytra with a rather distinct transverse depression below the base,

strongly punctured in rows, the sides with two or three strongly raised coste towards the apex, the suture

also narrowly but distinctly raised; legs fulvous.

Hab. Mexico, Refugio in Durango (fHége).

This insect agrees in shape and in its main characters with Agbalus; the specimens

received are apparently all females. The dark purplish colour and the fulvous antenne

and legs distinguish A. hégei from its allies from our region.

6. Agbalus tenebrosus.

Oblong-ovate, dark greenish-zeneous; the lower joints of the antenne fulvous; thorax transversely convex,

minutely punctured ; elytra finely and closely semiregularly punctate-striate.

Length 13 line.

Head finely and remotely punctured on the vertex; the clypeus more closely punctate, not separated from the

face, its lower edge concave-emarginate; eyes sinuate at their lower margin; labrum piceous ; terminal

joint of the palpi robust and rather elongate; antenne not extending much beyond the base of the thorax,

robust, the lower six joints fulvous (the first piceous above), the others black and much thickened; thorax

transversely convex, its sides strongly rounded, the anterior margin straight, the angles acute but not

produced, the surface very finely and rather closely punctured ; scutellum broad, smooth ; elytra slightly

widened towards the middle, rather short, the shoulders scarcely prominent, the base with a very obsolete

depression, the surface punctured in closely-arranged but not very regular rows, which are more widely

separated towards the apex, the interstices flat ; underside metallic greenish ; legs robust, the tibie clothed

with long fulvous pubescence near the apex; prosternum elongate, narrowed between the coxe.

Hab. Panama, Volcan de Chiriqui (Champion).

A, tenebrosus, of which only a single example was obtained, is much more typical of

the genus than many of its congeners, although the posterior tibial spine, peculiar to

the male in some species, is here absent; the specimen described is undoubtedly a

male, it having the anterior tarsi dilated. In the robust antenne and legs and the

general shape it agrees with Agbalus; the elytra have a slight purplish tint when

viewed in certain lights. |

7. Agbalus violaceus.

Corysthea violacea, Jac. huj. op. p. 154, t. 9. fig. 3.

According to Lefévre (Ann. Soc. Ent. Fr. 1889, p. 340) this species should be placed

in Agbalus; but as in my opinion neither this genus nor Corysthea is sufficiently well

defined (containing species with short, robust, and long filiform antennee and emar-

' AGBALUS.—EUPHRYTUS, — 207.

ginate or nearly truncate prosternum respectively), it matters but little where the

insect is placed. A. violaceus has the antenne long and filiform, and the prosternum

slightly emarginate.

EUPHRYTUS (p. 124).

Euphrytus zneus (p. 125).

Var. Entirely fulvous, the apical joints of the antenne black.

To the Mexican locality given, add :—Refugio in Durango, Cuernavaca in Morelos,

Acapulco and Chilpancingo in Guerrero, Mexico city (Hége).

E. eneus, like the other members of this genus, seems to vary greatly in many

respects, and it is a species very difficult to define. Entirely fulvous specimens (the

elytra with a slight eneous gloss) have been obtained at Chilpancingo.

Euphrytus simplex (p. 125). |

To the Mexican localities given, add:—Milpas in Durango (Forrer), Durango city,

Jalapa, Mexico city (Hége).

It is somewhat doubtful whether LE. simplex is specifically distinct from H. @neus, or

is merely a variety in which the femoral tooth is not developed. The specimens vary

to such an extent that I am unable to form any conclusive opinion. As a rule,

E. simplex is smaller than E. wneus, and has the femora unarmed in both sexes.

2(s). Euphrytus pallipes. |

Narrowly elongate, obscure neous; the basal joints of the antenne and the legs pale flavous; thorax very

closely punctured ; elytra a little more strongly punctured, the punctures arranged in close rows; posterior

femora in the male with a triangular tooth.

Length 23 lines.

Hab. Mexico, Durango and Chihuahua city (Hége).

E. pallipes may be known from E. eneus, E. simplex, &c. by its smaller and more

narrowly elongate general shape. The antenne, which extend to two-thirds the length

of the body, are generally pale fulvous, with the apex of each joint darker, and the

terminal joint entirely black; the apical joint is broadly triangularly widened, its

extreme apex being pointed. The thorax is very closely punctured. The legs are

pale flavous (the lower portion of the femora alone being darker); the posterior femora

in the male are strongly toothed. The colour of the upper surface is brassy-zneous.

Four specimens, agreeing entirely in the above particulars.

2(). Euphrytus intermedius.

Piceous, the base of the antenne and legs pale flavous ; thorax very finely and closely punctured ; elytra more

strongly punctate, the punctures geminate, the interstices costate ; femora unarmed.

Length 2-23 lines.

Head rather sparingly punctured, with a more or less distinct metallic greenish gloss, the clypeus more closely

208 PHYTOPHAGA.—SUPPLEMENT.

punctured, the labrum fulvous, the palpi flavous; antennz nearly as long as the body in the male, the

five or six lower joints pale flavous, the others fuscous; thorax transverse, the sides but slightly rounded,

narrowed towards the apex, the angles obtuse, the surface very closely and finely punctured, piceous, with

a more or less distinct greenish gloss; elytra not wider at the base than the thorax, and of the same

colour, nearly parallel, the punctures closely and irregularly placed anteriorly, but arranged in double

rows towards the apex, the interstices costate ; femora unarmed; the first joint of the posterior tarsi as

long as the following three joints united.

Hab. Mexico, Northern Sonora (Morrison), Chilpancingo in Guerrero, Puente de

Ixtla in Morelos (H. H. Smith), Iguala in Guerrero (Hége).

Smaller and less elongate in shape than its congeners, and piceous in colour. The

thorax is much more finely punctured than in £. simplex; and the elytral interstices

are more or less raised (especially in the specimens from Chilpancingo and Puente de

Ixtla, these also having the punctuation more distinctly arranged in double rows). In

some of the females the antenne and legs are nearly black. The male insects are

generally smaller, pale brown in colour, and have each joint of the antenne furnished

below with a long, stiff, whitish bristle (this can be seen only in certain lights, and not

in all specimens).

Euphrytus fulvicollis (p. 126).

A renewed examination of the specimens referred to HL. fulvicollis has convinced me

that they do not all belong to the same species; the type has only been obtained at

Cuernavaca, the other localities should be erased and transferred to the following closely

allied form which I now describe under the name of E. varipennis. The insect figured

under the name of E£. fulvicollis is also referable to E. varipennis.

5. Euphrytus varipennis. (£. fulvicollis, Tab. VIII. fig. 19.)

Euphrytus fulvicollis, huj. op. p. 126 (pars).

Bluish-black, the head, thorax, and legs fulvous; thorax impunctate; elytra very finely geminate-punctate-

striate, dark blue, violaceous, or green, scarcely shining; femora unarmed.

Length 2-23 lines.

Hab. Mexico, Puebla, Capulalpam, Juquila, Oaxaca (Sallé), Orizaba (Flohr), Xucu-

manatlan in Guerrero (H. H. Smith).

E. varipennis differs in the following particulars from E. fulvicollis :—The antenne

are black, with the exception of the basal two or three joints, which are fulvous; the

elytra (instead of being finely and closely punctured in rows) are very finely geminate-

punctate-striate, and have the interstices slightly convex ; and the femora are not dilated

into a tooth. An example from Guatemala (Sal/é), of smaller size and with long and

slender antenne, is perhaps the male of the same species; this specimen has the elytra

more shining and with fine irregular rows of double punctures, and the tarsi black ; it

is possible that it belongs to yet another species.

EUPHRYTUS. 209

6. Euphrytus fulvicornis.

Bluish-black ; the antenne, head, and thorax fulvous; elytra dark bluish or greenish, opaque, very finely

geminate-punctate-striate.

Length 2-23 lines.

Hab. Mexico, Ventanas and Milpas in Durango (Forrer).

Closely allied to L. varipennis, but differing from it by the entirely fulvous antenne

and by the opaque and silky appearance of the elytra, the punctuation of which is

extremely fine, and in some specimens scarcely perceptible. The thorax is impunctate,

and shaped as in E. varipennis; the femora are also unarmed. The specimens received

are apparently all females.

7. Euphrytus umbrosus.

Elongate, subcylindrical, dark sneous, the base of the antenne pale; thorax finely and closely punctured ;

elytra more strongly and very closely punctured, the interstices at the apex convex.

¢g. The antenne more than half the length of the body; the posterior femora toothed.

@. The antenne much shorter; the posterior femora unarmed. ~

Length 3 lines.

Hab. Mexico, Chilpancingo, Omilteme, and Tepetlapa, all in Guerrero, Cuernavaca in

Morelos (H. H. Smith).

Of darker general colour than ZH. wneus; the antenne black (the second to the fourth

joints excepted) and much shorter, the terminal joint in the male curved and widened ;

the legs dark neous; the tooth on the posterior femora in the male smaller and shorter,

and the intermediate tibie curved near the apex. The armed femora and dark legs

distinguish it from E. simplex ; and the shorter antenne and their colour from the last-

named species and from £. varicornis also.

8. Euphrytus varicornis.

Elongate, obscure dark bronze ; antenne testaceous, the seventh and the two terminal joints fuscous; thorax

very closely punctured ; elytra very closely semipunctate-striate ; legs testaceous; femora unarmed.

Length 3 lines.

Hab. Mexico, Chilpancingo, Iguala, and Amutla, all in Guerrero (Hoge, H. H. Smith).

E. varicornis is very closely allied to E. simplex, and is possibly only a variety of

that species; it differs principally by the colour of the antenne, which is constant in

the eight examples before me. The thorax is also rather longer and devoid of any

depression. In the specimens which I suppose to be the females the antenne are only

half the length of the body.

9, Euphrytus pallidus. (Tab. XL. fig. 13.)

Elongate, entirely pale flavous; thorax minutely and closely punctured; elytra more strongly and very closely

punctured, the interstices slightly raised on the disc, distinctly costate near the apex.

Length 23 lines.

Head closely and distinctly punctured; eyes large and prominent, sinuate; antenne two-thirds the length of

the body, flavous, the third and fourth joints equal; thorax about one half broader than long, the sides

rounded and slightly sinuate, the surface extremely minutely and closely punctured, flavous ; scutellum

with a few fine punctures; elytra rather strongly and closely punctured, the punctures arranged almost

in double rows, the interstices transversely rugose at the sides, slightly raised in narrow lines on the disc,

these lines being more strongly raised and broader at the apex ; femora unarmed ; the first joint of the

posterior tarsi as long as the following three joints united; prosternum narrowly elongate.

Hab. Muxico, Iguala in Guerrero (Hége).

A typical species, recognizable at once by the entirely flavous colour.

10. Euphrytus nigritarsis.

Fulvous, the antenne (the three basal joints excepted), the apices of the tibie, and the tarsi black; thorax

extremely closely and finely punctured; elytra metallic green, subgeminate-punctate-striate, the inter-

stices slightly raised.

Length 3 lines.

. Head finely and rather closely punctured; antenne black, the lower three joints fulvous, the terminal

joints gradually thickened ; thorax scarcely twice as broad as long, the sides slightly sinuate, narrowed in

front, with a narrow flattened margin, the surface extremely finely and closely punctured throughout ;

scutellum fulvous; elytra with closely arranged double rows of strong punctures, separated by narrow

longitudinal smooth spaces, metallic green; underside and legs fulvous, the apices of the tibis and the

tarsi black; femora unarmed.

Hab. Mexico, Chilpancingo in Guerrero (Hége).

11. Euphrytus elongatus. (Tab. XL. fig. 14.)

Elongate, blackish or purplish-sneous ; thorax closely and finely rugose; elytra strongly and closely geminate-

punctate-striate, the interstices longitudinally raised.

3. Antenne robust, the terminal joints gradually widened and flattened; the posterior femora obsoletely

angulate.

. Antenne much shorter, the joints scarcely widened ; the posterior femora simple.

Length 3 lines.

dé.

Head rugosely punctured; the antenne robust, two-thirds the length of the body, the first joint short,

nearly subquadrate, piceous above, the second joint very short, the third and fourth joints fulvous, the

third widened at its apex and much shorter than the fourth, the following joints subtriangularly widened,

black, the apical one concave and sinuate at its apex; thorax about one half broader than long, the sides

rounded, narrowed in front, the surface very closely punctured and finely rugose throughout ; elytra with

strong double rows of punctures, divided by longitudinal narrow raised lines; the first joint of the posterior

tarsi as long as the following two joints united, the claw-joint very long and slender.

Hab. Mexico, Durango city (Hoge).

The colour of this very elongate and narrow species is dull black, purplish, or eeneous ;

the general shape, the structure of the antenne in the male, the rugosely sculptured

thorax, and the semicostate elytra separate E. elongatus from any of its allies.

12. Euphrytus humeralis. (Tab. XL. fig. 15.)

Elongate, black, the basal joints of the antenne testaceous; thorax closely and finely punctured; elytra

subgeminate-punctate-striate, black, a large subquadrate spot at the shoulders rufous.

terminal joints elongate, but slightly thickened ; thorax transverse, the sides nearly straight, narrowed in

front, with a narrow greenish margin, the disc finely and closely punctured, black; elytra black, with a

large subquadrate rufous spot surrounding the shoulders, slightly depressed below the base, the disc closely

geminate-punctate-striate, the interstices forming narrow longitudinal spaces, which become costate near

the apex; legs and underside black ; femora unarmed.

Hab. Mexico, Chilpancingo (H. H. Smith). A single specimen.

13. Euphrytus (?) semirugosus.

Elongate, dark xneous; antenne short, the apical joints thickened; thorax very closely and rather strongly

punctured ; elytra as closely and more strongly punctured, the interstices at the sides semirugose.

Length 2 lines.

Head not closely but distinctly punctured on the vertex; the eyes widely separated, sinuate at the inner

margin; labrum fulvous; terminal joint of the palpi thickened, its apex subtruncate, piceous; antenne

(2) only extending a little beyond the base of the elytra, black, the basal joints testaceous at their apex,

the terminal five joints thickened ; thorax twice as broad as long, the sides rather strongly rounded, the

anterior angles slightly thickened and produced, the surface very closely punctured (especially near the

sides), and with a more or less distinct lateral depression; elytra narrowly parallel, more strongly punc-

tured than the thorax, the punctures arranged in very close, somewhat geminate, rows near the suture,

but becoming irregular at the sides, the sutural interstices slightly raised in lines, the lateral inter-

stices obscurely wrinkled; legs piceous or black; femora unarmed, their base sometimes paler; the first

joint of the posterior tarsi as long as the following two joints together ; prosternum comparatively broad,

not much narrowed between the coxe.

Hab. Mexico, Refugio in Durango (Hége).

I place this comparatively small species, of which only female specimens seem to

have been obtained, in Kuphrytus, as it agrees with the members of that genus in its

general shape; it differs, however, from the allied forms in the short and thickened

antenne, the short metatarsus of the posterior legs, and the broader prosternum.

E. semirugosus may be known by its small size, short antenne, and semirugose lateral

interstices of the elytra.

14. Euphrytus apicicornis. (Tab. XL. fig. 16.)

Greenish-zneous, the antennae (the apical three joints excepted), elytra, and legs fulvous; head and thorax

finely and closely punctured; elytra rather regularly punctate-striate; femora unarmed.

Length 3 lines.

Head finely and rather remotely punctured on the vertex, the lower portion and the clypeus more strongly and

closely punctured ; the latter wedge-shaped, bounded on each side by a smooth triangular space; labrum

and mandibles fulvous; antenns two-thirds the length of the body, fulvous, the basal joints very slender,

the apical three joints fuscous ; thorax about one half broader than long, the sides very slightly rounded, the

anterior angles thickened, the surface closely and finely punctured, greenish-zeneous, somewhat depressed

near the posterior angles; scutellum metallic swneous; elytra nearly parallel, slightly transversely

depressed below the base, reddish-fulvous, the punctuation stronger than that of the thorax, and arranged

in close and rather regular rows, the interstices forming narrow, somewhat raised, smooth longitudinal

spaces; underside dark wneous, the last abdominal segment obscure fulvous; legs fulvous; the first joint

of the posterior tarsi as long as the following three joints together ; prosternum narrowly elongate.

Hab. Mexico, Ciudad in Durango (Forrer).

Of this distinct species only one specimen was obtained ; the colour of the antenne,

2e2

the comparatively narrow thorax, and the colour of the elytra separate L. apicicornis

from its congeners. .

15. Euphrytus (?) rugosus. (Tab. XL. fig. 17.)

Elongate, subdepressed, obscure seneous; the head, thorax, and legs rufous; elytra greenish-eneous, closely

punctured and finely transversely rugose; tarsi black.

Length 3 lines.

Head closely rugose-punctate, rufous; the clypeus transverse, separated from the face by a transverse groove,

rugosely punctured; the labrum with a large black patch; mandibles and palpi black; antenne (9 )

scarcely extending to the middle of the elytra, black, pubescent, the basal joints fulvous at the apex, the

seventh and following joints gradually thickened; thorax transverse, twice as broad as long, the sides

strongly rounded, the anterior angles obtuse, the surface finely and very closely semirugose punctate,

rufous; scutellum black ; elytra obscure greenish-ceneous, more strongly punctured than the thorax, the

interstices transversely rugose or wrinkled throughout, with traces of longitudinal narrow lines on the

disc and near the apex; legs rufous, the tarsi black; the first joint of the posterior tarsi as long as the

following two joints together ; prosternum rather broad, widened and truncate posteriorly.

Hab. Mextco, Yolos (Salié).

A single specimen, apparently a female. This insect is provisionally included in

Euphrytus, from the typical forms of which it differs in the broader prosternum and in |

the shorter metatarsus of the posterior legs. E. rugosus may be easily recognized by

its coloration and sculpture.

THERSES. (To follow the genus Euphrytus, p. 126.)

Body oblong ; antennz subfiliform, the terminal joints thickened ; thorax transverse, strongly narrowed in

front ; elytra semipunctate-striate ; legs rather slender; femora unarmed ; tibiee channelled; claws bifid ;

prosternum narrowly elongate; the anterior margin of the prothoracic episterna concave.

This new genus may be at once distinguished from all others of the Iphimeine by

the bifid claws. The two species referred to it, both of which are from Mexico, have

somewhat the general appearance of certain members of the family Erotylide; they

differ from Euphrytus and the allied genera in the shape of the thorax, as well as by

the form of the claws. |

1. Therses nigricollis.

Body narrowed posteriorly, black; head and thorax opaque, impunctate; elytra metallic greenish, finely

geminate-punctate-striate, the interstices more or less longitudinally convex.

Length 2 lines.

Head impunctate ; the eyes widely separated, slightly sinuate at their inner margin ; the antenne extending

to the middle of the body, black, the lower three joints fulvous at the apex, the third joint distinctly

longer than the second but shorter than the fourth, the apical joints shorter and stouter ; thorax rounded -

at the sides and strongly narrowed in front, the anterior angles not produced, the surface opaque, black,

impunctate (under a very strong lens, some minute punctures are visible); scutellum black ; elytra nar-

rowed and pointed towards the apex, metallic greenish, geminate-punctate-striate, the punctures towards

the apex arranged singly, the interstices (especially towards the sides) longitudinally convex ; underside

and legs black, the knees piceous, the first joint of the posterior tarsi as long as the following two joints

together,

THERSES.—PSEUDOCHORIS. 213

Hab. Mexico, Jalapa (Hoge).

A single specimen, apparently a female.

2. Therses ochripes.

Elongate, slightly narrowed posteriorly, black; the head, antenns, thorax, and legs fulvous ; elytra greenish-

eeneous, extremely finely punctured in rows.

Length 14 line.

Head impunctate, the clypeus with a few minute punctures only ; antenne fulvous, about two-thirds the length

of the body, the third and fourth joints equal, the following joints slightly and gradually thickened ; thorax

twice as broad as long, the sides rounded near the base, strongly narrowed in front, the anterior and

posterior margins nearly straight, the surface opaque, impunctate, fulvous ; elytra of a brassy-green colour,

with rows of minute punctures, which are a little more distinct at the sides, the interstices somewhat silky

in appearance ; legs entirely fulvous.

Hab. Mexico, Chilpancingo in Guerrero (Hége).

PSEUDOCHORIS.

Elongate, subparallel. Eyes entire. Antenne filiform, the terminal joints but slightly thickened, the second

joint short, the others nearly equal in length. Thorax transverse, the anterior margin nearly straight,

the sides moderately rounded, the anterior angles not produced. LElytra punctured in rows. Femora

unarmed. The first joint of the posterior tarsi as long as the following two joints together. Claws

appendiculate. Prosternum narrowed between the coxe, its base truncate. The anterior margin of the

prothoracic episterna concave.

This new genus is proposed for the reception of an insect having the general

characters of the Iphimeine, without agreeing entirely with any of the genera of

that group. The filiform, scarcely thickened antenne and the truncate base of the

prosternum separate Pseudochoris from Choris; the transverse thorax, entire eyes, and

much shorter metatarsus of the posterior legs from Euphrytus, to which genus, however,

Pseudochoris is closely allied.

1. Pseudochoris fulvicollis. (Tab. XL. fig. 18.)

Obscure greenish-zneous, the head, antenna, thorax, and legs fulvous ; thorax finely punctured; elytra metallic

green, strongly punctured, the interstices at the sides obsoletely transversely rugose.

Var. Thorax and elytra obscure seneous.

3g. Head rather closely punctured, with a metallic green gloss; palpi fulvous, the terminal joint robust;

antenne extending to a little beyond the middle of the elytra, fulvous; thorax about one half broader than

long, scarcely narrowed in front, the sides evenly and moderately rounded, with anarrow margin, the base

very slightly produced at the middle and accompanied by a deeply impressed line, the anterior angles some-

what oblique and thickened, the surface finely and rather closely punctured (especially .at the sides),

fulvous, with a slight metallic gloss; scutellum metallic green, smooth, not broader than long; elytra

parallel, with a very shallow depression below the base, metallic green or bronze, rather strongly

punctured in rows, the punctures on the disc finer and more distant than those at the sides, the lateral

interstices transversely rugose ; legs fulvous, rather robust; the first joint of the anterior tarsi dilated

in the male, that of the posterior pair not longer than the following two joints together.

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

Some specimens, especially females, have the thorax and elytra eneous, and the

terminal joints of the antenne black; these examples much resemble Coytiera fulvipes,

which may, however, be distinguished by the strongly rounded sides and acute angles

of the thorax.

| EPHYRHA. (To precede the genus Coytiera, p. 126.)

Ephyrea, Lefévre, Aun. Soc. Ent. Fr. 1889, p. 332.

Ephyrea contains some small species having the general shape of Noda, but with

more elongate antenne and a strongly transverse thorax. Two species from the State

of Panama are here referred to it.

1. Ephyrea exigua.

Greenish-black, the basal joints of the antenne and the legs fulvous; thorax and elytra obscure violaceous-

black, the former finely and remotely punctate, the latter finely punctate-striate.

Length 3 line.

Head finely’ and remotely punctured, the clypeus not separated from the face, the eyes entire, the labrum

and palpi fulvous; antenne more than half the length of the body, fulvous, the seventh and following

joints stained with fuscous and gradually thickened ; thorax very short and transverse, the sides strongly

widened and rounded at the middle, and: thence to the base nearly straight, the surface finely and remotely

punctured, the punctures of unequal size, the anterior angles produced into a small tooth; elytra with a

shallow depression below the base, of a dark violaceous or purplish colour, distinctly and regularly

punctate-striate, the punctures somewhat geminate towards the base, in single rows and more distant

near the apex; legs fulvous; prosternum broad, widened at the base.

Hab. Panama, Volcan de Chiriqui (Champion).

2. Ephyrea isthmica. (Tab. XL. fig. 19.)

Elongate, strongly narrowed posteriorly, metallic greenish; antennsw and legs fulvous; thorax rather closely

punctured ; elytra strongly geminate-punctate-striate, the sides with three sharply raised longitudinal

coste.

Length 1 line.

Head remotely and finely punctured, the interstices minutely granulate; labrum and mandibles fulvous ;

antenne: extending to about one-third the length of the elytra, fulvous, the terminal joints strongly thick-

ened ; thorax short, more than twice as broad as long, the sides strongly widened and rounded, the ante-

rior angles dentiform, the surface closely punctured at the sides, more sparsely so on the disc; scutellum

impunctate; elytra narrow and convex, pointed at the apex, the punctuation stronger than that of the

thorax, arranged in double rows anteriorly, but in single rows near the apex, the interstices somewhat

opaque, raised into three sharp coste at the sides, of which the intermediate one is the highest, this

latter commencing at the shoulder, and extending towards the apex, where it is joined to the pre-

ceding costa; legs fulvous.

Hab. Panama, Peta Blanca (Champion).

A single specimen. In its narrowly elongate and pointed shape this insect differs

totally from the allied species; but the form of the thorax and other structural

characters agree with Ephyrea. It is probable that the example before me is of the

female sex. . isthmica is well distinguished by the sharply raised lateral coste of

the elytra.

COYTIERA.—CHORIS. 215

COYTIERA (p. 126).

Coytiera fulvipes (p. 126). (Corysthea hégei, Tab. VIL. fig. 3.)

To the Mexican localities given, add:—Chilpancingo, Tepetlapa, and Soledad, all in

Guerrero (H. H. Smith), Iguala in Guerrero (Hoge),

In a single male specimen, obtained at Chilpancingo, the posterior femora are dilated

into a triangular tooth: the insect in this respect agrees with Huphrytus, although it

has the prosternum, and also the thorax, differently shaped. The elytra have a more

or less distinct depression below the base, and they vary in colour from cupreous to

metallic green or blue.

The insect figured on Tab. VII. under the name of Corysthea hégei is, as noted on

p. 154, only a variety of this species.

3. Coytiera costata.

Oblong, obscure wncous; the antenne and legs fulvous; thorax very closely and finely punctured; elytra

geminate-punctate-striate, the interstices longitudinally costate.

Var, Antenne and legs piceous.

Length 2 lines.

Head rather closely punctured, the eyes widely separated, the labrum fulvous; antenne nearly as long as the

body, filiform, the first joint thickened from the base to the apex, and slightly curved, the second very

small, the third and fourth joints equal, the following joints slightly longer; thorax transversely

subquadrate, the sides rounded, equally constricted at the base and apex, the anterior angles slightly

produced outwards, the surface very closely, evenly, and finely punctured throughout, with or without

a shallow fovea on each side; scutellum with a few minute punctures; elytra parallel, with seven or

eight distinctly raised longitudinal coste extending from the base to the apex, the interstices geminate-

punctate; legs robust, the femora thickened, the tibie bicarinate on each side, clothed with yellowish

pubescence, the first joint of the posterior tarsi scarcely so long as the following two joints united; claws

appendiculate ; prosternum slightly narrowed at the middle.

Hab. Mexico, Chilpancingo and Iguala in Guerrero (Hége).

Like C. fulvipes, the present species has not the facies of a Coytiera, but it agrees in

the principal structural characters with that genus. In the single female example

received, which was obtained at Chilpancingo, the antenne are much shorter than

in the male (from Iguala), and the terminal joints are much more robust; the elytral

punctuation is stronger; and the legs are piceous.

The species for which this genus was established are of small size, and prineipally

distinguished by the transversely-shaped thorax, its rounded margin, and the elongate

and narrowed prosternum. The Mexican representative described below does not

agree entirely in its structural characters with Choris, differences being visible in the

Narrowly elongate, subcylindrical, blackish, above brownish- or greenish-gneous ; the basal joints of the

antenne and the legs fulvous; thorax extremely closely punctured, the sides finely pubescent ; elytra

strongly and closely punctured, transversely rugose at the sides.

Length 13-12 line.

Head broader than long, strongly punctured, and sparsely clothed with short whitish pubescence; eyes very

widely separated, entire; clypeus transverse, not more closely punctured than the head, its lower edge

concave-emarginate; labrum and palpi fulvous, the terminal joint of the latter subcylindrical, piceous ;

antenns two-thirds the length of the body in the male, much shorter in the female, robust, black, the

lower four joints fulvous, the basal joint short and thick (almost cylindrical), stained with piceous above,

the second joint half the size, the following four joints nearly equal, the rest more thickened but elongate ;

thorax strongly transverse, more than twice as broad as long, the sides very strongly rounded at the

middle, entire, the anterior margin slightly produced in the centre, the anterior angles thickened but not

produced, the surface extremely closely and rather finely punctured, the interspaces slightly rugose, and

clothed with short pubescence at the sides; scutellum broadly ovate; elytra slightly wider at the base

than the thorax, convex and subcylindrical, eneous, the disc much more strongly punctured than the

thorax, the punctures arranged in irregular rows, the interstices here and there raised in longitudinal

lines, transversely rugose at the sides; legs robust, fulvous, the femora incrassate ; tibie longitudinally

carinate, widened towards the apex, the latter deeply hollowed; claws appendiculate ; prosternum strongly

convex, narrowed at the middle and elongate, its base truncate.

Hab. Mexico, Chilpancingo in Guerrero (Hoge, H. H. Smith).

In general appearance this insect closely resembles a Spheropis, the antenne, thorax

and its pubescence, as well as the shape of the prosternum, agreeing with that genus ;

but it has the claws appendiculate (not bifid), and the species is therefore better placed

in Choris.

CLISITHERA. (To precede the genus Beltia, p. 128.)

Clisithera, Baly, Journ. Ent. ii. p. 220 (1864).

This genus belongs to the group Iphimeine, and as yet contains only a single species ;

it is principally distinguished by the dilated intermediate joints of the antenne and

the transverse thorax.

TALURUS. (To precede the genus Metaryonycha, p. 128.)

Talurus, Lefévre, Ann. Soc. Ent. Fr. 1889, p. 337.

This genus has been lately established by Lefévre on two species placed by me in

Rhabdophorus* ; these species differ, however, from Rhabdophorus in the very transverse

thorax, the sides of which are rounded and entire, the filiform antennee, and the longer

first joint of the posterior tarsi. Lefevre erroneously describes the eyes as entire; they

are distinctly emarginate on their inner edge.

Testaceous; thorax closely punctured, the lateral margins obsoletely bidentate; elytra strongly and closely

punctured in rows, sparsely pubescent, strongly costate at the apex, a subquadrate spot at the base and a

transversely shaped one below the middle metallic green.

Length 33-43 lines.

Head rather closely and strongly punctured at the sides, deeply triangularly depressed between the eyes, the

apices of the mandibles black ; antenne long and slender, entirely testaceous ; thorax about one half

broader than long, closely but irregularly and not very strongly punctured, the lateral margins obsolétely

bi- or tridentate or merely sinuate, the anterior angles produced ; elytra not very deeply punctured, more

sparsely so near the suture than at the sides, the interstices strongly costate near the apex, and sparingly

clothed with stiff fulvous hairs, the shoulders with a subquadrate metallic green spot not extending to

either margin, another spot of the same size, but of more transverse shape, placed below the middle; the

first joint of the anterior tarsi widened, and the intermediate tibie strongly curved at the apex, in the

male; the female with three or four short cost at the base of the elytra within the metallic green spot.

218 PHYTOPHAGA.—SU PPLEMENT.

In its markings MV. hirsuta resembles many of its congeners (especially M. chloro-

spilota), but is well distinguished by the entirely testaceous antenne, and the non-costate

elytral interstices on the disc and their pubescence; the latter consists of a single row

of erect hairs on each interstice, but is very marked in well-preserved examples. In the

female the thorax is, as usual, more transverse. Many specimens. —

2(s). Metaxyonycha panamensis. (Tab. XL. fig. 23.)

Testaceous, the intermediate joints of the antenne piceous; thorax remotely punctured, the sides tridentate ;

elytra strongly and irregularly punctured in rows, the interstices costate at the apex, a humeral spot and

a narrow short transverse band below the middle metallic blue or green.

Length 34-43 lines.

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

Although closely allied to several other species of the genus, M. panamensis, of

which many specimens are before me, differs constantly in the following particulars :—

The antenne have the fifth and the following two joints piceous; the thorax is irre-

gularly and remotely punctured (the species differing in this respect from M. tridentata) ;

the elytra have smaller metallic spots, and the posterior one is in the shape of a short.

transverse narrow band (thus agreeing with UW. tridentata, but in that species the

elytral interstices are convex throughout—in the present insect they are only so at the

apex). MM. panamensis may be separated from various South-American forms by the

entirely testaceous legs, and from MM. hirsuta by the glabrous elytra. Several

examples have the left lateral margin of the thorax nearly entire or unidentate, and in

others the teeth are placed in different positions to those of the right side.

5. Metaxyonycha variolosa.

Testaceous; the antenns (the basal three joints excepted) black; thorax deeply and rather closely punctured,

bifoveolate at the sides, the latter tridentate; elytra metallic green, rugosely punctured, the lateral and

apical margins testaceous ; intermediate tibie emarginate at the apex.

Length 4 lines.

Hab. Mexico, Tapachula in Chiapas (//ége).

A single specimen. This species has much the appearance of Prionodera chloroptera

(Germ.); the colour of the antenne and the different structure of the thorax and of the

intermediate tibize will, however, separate WZ. variolosa from it. The three teeth on the

lateral margin of the thorax are very distinct; the elytra are very strongly transversely

rugose between the punctures, and also show traces of longitudinal coste near the

suture; the underside and legs are entirely testaceous.

sides ; elytra metallic green, deeply punctured and transversely rugose, the lateral and apical margins

_ fulvous.

Length 3 lines.

Head rather closely impressed with large and small punctures; antenne fulvous, the sixth and seventh and the

apical two joints black; thorax about one half broader than long, the sides with two more or less distinct

teeth, the anterior angles produced, the surface irregularly and rather closely punctured, the punctures

unequal in size; scutellum fulvous; elytra bright metallic green, closely and strongly rugose-punctate,

the interstices longitudinally and also transversely raised, the lateral and apical margins evenly and rather

broadly fulvous; underside and legs fulvous,

Oblong, piceous; the lower five joints of the antenne, the head, thorax, and legs rufous; elytra opaque, dull

greenish, very closely punctured, with three or four obsolete longitudinal costz, the extreme apex dentiform

and rufous in colour.

Length 3 lines.

Head coarsely rugose at the middle, more finely so on the vertex; antenn less than half the length of the

body, black, the lower five joints rufous; thorax one half broader than long, narrowed in front, the sides

undulate, and with a flattened margin, the surface irregularly impressed with large and small punctures,

the interspaces wrinkled at the sides, the disc with a smooth narrow longitudinal space in the middle ;

scutellum fulvous, its apex truncate; elytra scarcely widened at the middle, opaque, greenish, very closely

punctured, the interstices finely granulate, but hardly rugose, the sides with two distinct, the dise with

two very obsolete, longitudinal coste, the extreme lateral margin at the apex rufous, the apex itself

produced into a tooth ; below nearly black, the sides of the breast and the legs rufous.

Hiab. Mexico, Refugio in Durango, Durango city (Hége), Maravatio (£lohr).

This species is perhaps nearest allied to P. dispar; but differs from that insect and

most of its allies in the elytra being simply punctured (not rugose) and having the

apex produced. I have received a single specimen from Mr. Flohr, and a dozen others

were obtained by Herr Hoge; some of these latter have the antenne fulvous, with the

seventh and apical joints alone fuscous.

piceous or fulvous.

Length 3 lines.

Hab. Mexico, Santa Clara in Chihuahua, Ventanas in Durango (Hoge).

Of broadly ovate, medially widened shape, depressed above; the elytra deeply punc-

tured, and the interstices transversely rugose, with traces of longitudinal coste near

the suture and apex. The elytra in the female have more strongly raised transverse

wrinkles and a distinct costa near the lateral margin. PP. sutwrale is distinguished

from its congeners by the flavous sutural and lateral margins of the elytra; the antenne

generally have the four basal joints flavous ; the intermediate tibiz are deeply emarginate

Additional specimens of both sexes since received agree with the type, and differ

from C. splendida in the way described ; another distinctive character is to be found in

the central metallic green mark of the thorax, which in C. splendida is reduced toa

narrow longitudinal stripe, while in the present species it assumes the shape of a broad

triangular patch. It is not impossible, however, that the sculpture may vary, and I

have as yet only seen two specimens of C. splendida.

Var. Entirely fulvous, with the exception of a common transverse more or less distinct piceous mark below the

base of the elytra.

To the localities given, add:—Panama, Bugaba, Volcan de Chiriqui, Caldera

(Champion).

The variety, which at first sight seems quite distinct, was collected in numbers in

Chiriqui together with the typical form; it cannot be mistaken for C. beltt (which has

also a mark at the base of the elytra), as it is smaller, and has a differently shaped

thorax, and differently coloured antenne and legs. Some examples show a distinct

metallic gloss over the fulvous ground-colour.

Panama specimens differ somewhat from the typical form in having the thorax and

elytra less closely punctured. The general colour of C. fastidiosa is greenish-eneous, or

fulvous with a metallic gloss; the thorax is more or less distinctly bidentate or biangu-

late at the sides; the elytra have very closely arranged double rows of punctures, and

the interstices very obscurely longitudinally raised and smooth; the antenne and legs

are fulvous. Some examples are entirely fulvous.

From an examination of the large amount of additional material since received,

—C. laticollis, Jac. (of which an example is figured on Tab. VII. fig. 6), proves to be

only a variety of C. impressa, from which it differs in its less closely punctured thorax.

C. impressa varies greatly in size, sculpture, and shape, and the legs also vary in colour,

being either fulvous with black tarsi or entirely dark blue; the species may be princi-

pally known by its dark blue colour, and by having the elytra impressed below

the base.

Central-American examples agree in all essential details with typical forms contained

23 (a). Colaspis sculpta.

Fulvous, the apical joints of the antenne fuscous; above metallic green or eneous; thorax subremotely and

strongly punctured, the sides angulate at the middle; elytra punctate-striate near the suture, the lateral

interstices strongly transversely rugose.

Length 23 lines.

Hab. PanaMa, Bugaba, Volcan de Chiriqui, Tolé (Champion).

Closely allied to C. compta, from which it differs thus :—The four or five lower joints

of the antenne are fulvous; the punctuation of the thorax is coarser and much more

remote, with the interspaces smooth and somewhat raised; the elytra are more strongly

punctured, the lateral interstices are rugose, and the basal depression is much shallower.

In C. compta the elytra have a cupreous basal spot and band, this being entirely absent

in C. sculpta. A dozen specimens were obtained.

This is a species of rather robust and parallel shape; fulvous, with the terminal

joints of the antenne, the apices of the tibie, and the tarsi black; the elytra are

metallic green, or fulvous with a metallic-green gloss, strongly transversely rugose at

the sides, punctate-striate near the suture; the punctuation of the thorax is remote

but strong; the length is four lines. The posterior femora in the male insect are

unusually thickened, almost as much as in a species of Halticide.

Found in numbers in Chiriqui; single specimens only have been obtained from

Mexico and Guatemala.

224 PHYTOPHAGA.—SUPPLEMENT.

27. Colaspis subzenea.

Obseure dark seneous or piceous, the antennw and legs flavous; thorax rather strongly and closely punctured,

the sides obsoletely bisinuate at the middle; elytra strongly and closely punctured, the interstices sub-

rugose and longitudinally costate.

Length 2-23 lines.

Hab. Guatemaua (mus. Stuttgart), near the city 5000 feet (Salvin).

C. subenea is of a uniform dull fusco-eneous colour. It varies a little in the amount

of the punctuation, the head and thorax, however, are generally rather closely and

distinctly punctate; the lateral margin of the thorax is not dentate but obsoletely

bisinuate; the elytra are almost rugosely punctured (owing to the interstices being

cregularly raised on either side), and have the longitudinal interspaces broad and

especially distinct near the apex, the interspaces costate, but not forming acute ridges.

C. subenea is perhaps nearest allied to C. interstitialis, Lefévre, in regard to colour, but

differs entirely in the shape of the thorax and in the elytral sculpture.

28. Colaspis inconspicua.

Obscure piceous or brownish-zneous; thorax more or less distinctly punctured, the sides dentate or subangulate

below the middle; elytra opaque or slightly metallic, geminate-punctate-striate, the interstices longi-

tudinally costate.

Length 24-3 lines.

Of rather elongate and convex shape; the head closely and somewhat rugosely punctured ; the antennz two-

thirds the length of the body, the basal joints more or less fulvous, the others fuscous ; thorax twice as

broad as long, narrowed in front, the sides narrowly margined, sinuate before and angulate or dentate

below the middle, the surface rather more strongly and closely punctured at the sides than at the middle ;

elytra with regular and deep rows of punctures arranged in pairs, the interstices strongly and regularly

costate throughout (each elytron with eight costa); legs piceous or fulvous.

Hab. Panama, Volcan de Chiriqui (Champion).—BraziL, San Paulo (coll. Jacoby).

This species, of which about twenty examples were obtained in Chiriqui, may be

known by its dull opaque colour: some specimens are nearly black, others are obscure

brownish-eneous. The thorax varies in the amount and intensity of the punctuation,

but the sides are always toothed below the middle; the elytra are regularly geminate-

punctate-striate, and have the interstices costate. A single specimen from San Paulo

in my collection does not differ in any particular from those from Chiriqui. C. inter-

stitialis, Lefévre, from Brazil, is a closely allied species; it is, however, of a much more

metallic and shining colour, and has the antenne and legs testaceous, the elytral coste

much less strongly raised, and the lateral tooth of the thorax situated at (not below)

the middle. Two specimens obtained by Mr. Champion differ from the others in having

a fulvous head and thorax.

29. Colaspis yucatana.

Oblong, convex, dark violaceous, the labrum and antennxy fulvous; thorax sparingly punctured, the sides

angulate just below the middle; elytra closely and deeply punctured at the sides, punctate-striate near

the suture, the interstices convex at the apex.

Length 2} lines.

COLASPIS.—ALETES. 225

Head of a more brilliant metallic bluish colour than the thorax and elytra, finely and rather sparingly punc-

tured, with a more or less distinct longitudinal groove down the middle ; labrum and palpi fulvous; antenne

entirely fulvous; thorax about twice as broad as long, moderately convex, the sides distinctly toothed

immediately below the middle, the punctuation rather deep and strong, the disc somewhat remotely, the

sides a little more closely punctured ; elytra convex, the punctures arranged in somewhat regular rows

near the suture, closely and irregularly placed at the sides in the male, more scattered in the female ;

underside and legs violaceous, the tarsi obscure piceous.

Hab. Muxico, Temax in North Yucatan (Gawmer).

The difference in the elytral punctuation in the two specimens obtained, and which

is apparently sexual, is considerable. The dull dark violaceous colour and the fulvous

antenne principally separate C. yucatana from its allies.

Chiriqui examples do not show any important differences from those from Muzo, of

which several have been kindly given to me by M. Lefévre; most of the specimens

from both localities have the knees, as well as the tibie and tarsi, black, and the

femora are not always entirely reddish-testaceous as stated by Lefévre.

Length 23-2? lines.

Of elongate and parallel shape; the head very closely and rather finely punctured ; labrum fulvous; antennz

(¢ ) two-thirds the length of the body, robust, fulvous, the basal joint thickened, rather short, the second

extremely short, the third and fourth joints equal, the others slightly longer ; thorax twice as broad as

long, the anterior and posterior margins nearly parallel, the sides rounded, obscurely bisinuate at the

middle, the surface densely impressed with fine punctures (which are a little less closely placed at the

middle), and with a short smooth median line near the base, the anterior angles slightly produced

outwards; scutellum a little longer than broad, with a few punctures ; elytra more strongly but not less

closely punctured than the thorax, the interstices (especially at the sides) finely transversely rugose, the

shoulders smooth and prominent; underside nearly black, very finely punctured; legs fulvous, sparingly

pubescent, the apices of the anterior tibiz produced into a strong tooth.

Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith, Hoge).

In the robust antenne in the male, the shape of the thorax and its sinuate margin,

&c., this species agrees well with Aletes. The female insect has the antenne shorter

and scarcely thickened. The upperside is very slightly metallic.

6. Alethaxius pubicollis.

Blackish-green, the basal joints of the antenne and the femora obscure fulvous; head and thorax geneous, the

latter closely punctured and sparingly pubescent ; elytra metallic greenish, strongly punctured, the sides

transversely rugose.

Length 14 line.

Elongate, parallel; the head rather remotely impressed with oblong punctures, eneous ; the clypeus transverse,

defiexed ; labrum piceous; antenne robust, two-thirds the length of the body, black, the lower four joints

more or less fulvous ; thorax more than twice as broad as long, the sides strongly rounded, very obscurely

angulate at the middle, the surface crowded with small punctures (especially at the sides), sneous, laterally

clothed with fine short whitish pubescence ; elytra with a very obsolete depression below the base, greenish,

the punctuation much deeper than that of the thorax, and obsoletely arranged in rows, the interstices at

the sides strongly transversely rugose ; legs robust; the underside and tibie nearly black.

Hab. Mexico, Chilpancingo (H. H. Smith).

A single specimen only of this small species was obtained. It is well distinguished

by the sparingly pubescent thorax and its general colour.

A single female specimen from Chontales served me for the description of this

species ; the numerous examples since received, obtained principally at Bugaba, do not

differ from it to any marked degree, and amongst them are many males; these latter

have the tarsi entirely black, and the first joint of the anterior pair (as usual) broadly

in Talurus.

Hab. Guatemaua, Cerro Zunil (Champion); Panama, near the city (Champion).—

CoLomBia 1.

Single specimens only were obtained by Mr. Champion in Guatemala and the State

of Panama ; one of these M. Lefévre has kindly compared with the type. &. curtus is

of comparatively short, parallel shape; the thorax is finely and rather sparingly

punctured, rounded or scarcely perceptibly angulate at the sides; the elytra are

punctate-striate near the suture, strongly punctured at the sides, where the interstices

are subrugose, those near the apex being costate. The length of the insect is about

one line and a half.

13. Rhabdopterus fulvus.

Fulvous, joints 7-9 of the antennz fuscous; thorax remotely punctured, the sides sinuate or angulate ; elytra

strongly and rather distantly punctured in rows, the interstices flat.

Length 13-14 line. ;

Of oblong, parallel shape; the clypeus with some remotely placed strong punctures, the rest of the head entirely

impunctate ; the antennz nearly extending to the end of the elytra in the male, fulvous, the seventh to

the ninth joints fuscous, the third and fourth joints slender, equal, the following joints still more elongate ;

thorax transverse, more than twice as broad as long, the anterior margin nearly straight, the sides

angularly widened or sinuate at the middle, the surface irregularly, remotely, and rather strongly

punctured ; elytra not wider at the base than the thorax, parallel, with an obsolete depression below the

base, strongly punctured within this depression and at the sides, more finely so towards the apex, where

the punctures are arranged in rows, the suture accompanied by a deeply impressed stria; prosternum

rather elongate, slightly narrowed between the coxe.

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

This comparatively small species agrees in shape, the structure of its thorax, antenne,

&c., with Rhabdopterus; it may be easily distinguished from the allied forms by its

uniform fulvous colour. .

HERMESIA. (To follow the genus Rhabdopterus, p. 193.)

Hermesia, Lefévre, Bull. Soc. Ent. Fr. 1877, p. clxxviil.

A few species from Tropical America, one of which extends northwards into our

region, are placed by Lefévre in this genus; they resemble Colaspis in general appear-

ance, but differ from it in having a rather more transversely-shaped thorax, the sides of

which are dilated and have a more or less sinuate margin.

Panama specimens are either of a metallic green or dark blue colour; they have the

thorax rather more transversely-shaped than in the type. The dark blue variety, which

agrees entirely with the green specimens in every way except in colour, has been

described by myself as a distinct species under the name of Rhabdophorus violaceus °.

CORYSTHEA (p. 153).

If Lefévre’s opinion of the true affinity of the single species included by me in this

genus proves to be correct, Corysthea must be erased from our list.

CHALCOPHANA (p. 154).

Chalcophana cincta (p. 155).

To the localities given, add:—Mexico, Cerro de Plumas, Matamoros Izucar (Hége),

Fortin and Atoyac in Vera Cruz (H. H. Smith).

The fulvous elytral band is only just indicated at the sides (and entirely obsolete on

the disc) in some specimens; it is very variable in width. I have also examples before

me with only the four (instead of the six) basal joints of the antenne fulvous.

Chalcophana championi (p. 155).

To the localities given, add :—Muxtico, Soledad, Xautipa, Chilpancingo, Amula, all

in Guerrero (H. H. Smith); Brrrish Honpuras, R. Sarstoon (Blancaneauz).

The Mexican specimens lately received have the first four joints of the antenne

fulvous and the elytral band prolonged laterally to the margins; in other respects they

agree with the type. They have the thorax narrower than in C. cincta, and much

more strongly and more closely punctured, and the elytral punctuation coarse and irre-

gularly placed in single rows, the interstices being more or less convex ; this is also the

case with the Guatemalan examples, which, however, have only two or three joints of

the antenne fulvous and the elytral band abbreviated at the sides.

Chalcophana ancora (p. 156).

The Guatemalan specimens referred to C. ancora prove on renewed examination to

belong to a closely allied but distinct species, which I describe below under the

CHALCOPHANA. 229

name of C. emarginata; the Guatemalan localities have therefore to be transferred to

that insect. The locality Costa Rica (Van Patten) should be erased altogether.

4 (a). Chalcophana emarginata.

2. Fulvous, the seven outer joints of the antenne black; thorax sparingly punctured ; elytra with a metallic-

green transverse band at the base and a round spot below the middle, coarsely punctured, the interstices

strongly longitudinally costate, the apex deeply emarginate.

Length 33 lines.

Hab. Guatemata, near the city, Zapote (Champion).

C. emarginata is the only species of the genus known to me in which the apex of

the elytra shows a deep emargination, the sutural angle (as in C. guadricostata) being

produced into a short tooth; this may or may not be a sexual peculiarity. The general

system of coloration is that of C. ancora; but the transverse basal band of the elytra in

the present insect is not so long, and its posterior margin is concave, while the posterior

spot (instead of being elongate-triangular) is of a more rounded shape. The sculpture

of the elytra is coarse and deep, and the coste are very strongly raised except near

the suture. These characters will assist in the recognition of C. emarginata.

4 (s). Chalcophana nigritarsis.

Fulvous, the antenne (the first four joints excepted) and tarsi bluish-black ; thorax irregularly and subremotely

punctured; elytra metallic green, the extreme lateral margins, the 4pex, and a transverse central band,

much widened at the middle, fulvous, closely geminate-punctate.

Length 22 lines.

Hab. Panama, Volcan de Chiriqui (Champion).

Similar in its system of coloration to C. cincta and several allied species, but differing

principally from these by the colour of the tarsi and by the elytral punctuation. The

antenne extend to two-thirds the length of the body, and have their four basal joints

fulvous. The thorax is twice as broad as long, scarcely narrowed in front, with rounded

sides; the surface is irregularly punctured, more closely so at the sides than on the

disc. The elytra have a slight but distinct post-basal depression and prominent

shoulders; the punctuation is arranged in close double lines which become indistinct

outwardly ; the fulvous band is lozenge-shaped across the suture and extremely narrow

towards the sides, where it widens again slightly and is connected with the similarly-

coloured lateral margin; the tarsi are metallic bluish-black.

The single example obtained is a male.

Chalcophana simplex (p. 162).

To the locality given, add :—Mextco, Tapachula in Chiapas (Hége).

The Mexican specimens obtained by Herr Hége during his second journey agree

sufficiently well with C. simplex to refer them to that species; they have, however, the

230 PHYTOPHAGA.—SUPPLEMENT.

basal four joints of the antenne fulvous (instead of three, as in the type), and the elytra

obsoletely costate at the sides in the female sex. The elytra are strongly costate at the

sides in the corresponding sex of most of the allied species, though they are not so in

the single female of C. simplex from which my description was taken. The compara-

tively fine punctuation arranged in single rows, which become almost obsolete near the

apex, in connection with the fulvous tibie and tarsi, form the principal characters of

distinction of C. simplex.

20. Chalcophana brevicollis.

©. Reddish-fulvous, the antenne (the basal two joints excepted), the apices of the tibia, and the tarsi black ;

thorax narrow, closely punctured ; elytra closely semirugose-punctate, metallic green, the extreme lateral

and apical margins fulvous ; prosternum very slightly emarginate.

Length 3 lines.

Head deeply punctured near the eyes, with a deep longitudinal median groove which ends in a fovea; clypeus

very minutely punctured; antenne bluish-black, the basal two joints fulvous; thorax not more than one

half broader than long, the sides obtusely rounded at the middle, rather strongly narrowed in front, the

anterior angles distinct but not produced, the surface closely impressed with punctures of unequal size ;

elytra deeply and closely punctured, the punctures near the suture arranged in semiregular rows, irregu-

larly and coarsely rugose at the sides, and with an indistinct costa running downwards from the shoulder

to the middle, the shoulders themselves prominent.

Hab. Muxico, Jalapa (Hoge).

A single female specimen. The comparatively narrow thorax and its close punctua-

tion, the rugosely punctured elytra without costz (the ill-defined humeral one excepted),

and the scarcely emarginate prosternum, separate this species from any of its similarly-

coloured allies.

21. Chaleophana quadricostata.

9. Reddish-fulvous, the eight terminal joints of the antenne, the apices of the tibise, and the tarsi black ;

head and thorax closely punctured; elytra metallic green, strongly geminate-punctate-striate, the sides

with four longitudinal coste, the lateral and apical margins fulvous, the sutural angle dentiform.

Length 3 lines.

Hab. Guatemata, Sabo in Vera Paz (Champion).

Two female specimens. Similar in coloration to C. godmani, C. hybrida, C. germari,

&c., but differing thus :—The head and thorax are much more closely punctured; the

elytral punctuation is strong and very closely placed, so that the geminate arrangement

is indistinct except at the sides, where the double rows of punctures are divided by

strongly raised coste (of these the inner one is more or less feeble); and the sutural

angle of the elytra is produced into a tooth. C. puncticollis, Lefévre, from Colombia,

is described as having black intermediate joints to the antenne and rufous tibie ;

C. landolti, Lefévre, has a deep basal depression to the elytra, instead of a shallow one

as in C. quadricostata. ‘The thorax in C. qguadricostata is rather short and strongly

transverse.

CHALCOPHANA.—THOOTES. 231

22. Chalcophana dimidiaticornis.

Pale fulvous ; antennew with the seventh joint fuscous ; thorax sparingly punctured ; elytra deeply semigeminate-

punctate-striate, the interstices slightly convex, a transverse band at the base and a rounded spot below

the middle metallic green.

Var, Elytra metallic green, the posterior portion of the suture and the apex fulvous.

Length 24-32 lines.

d. Head rather closely and distinctly punctured ; the clypeus separated from the face by distinct grooves ;

antenne nearly as long as the body, fulvous, the seventh joint (and sometimes the eighth also) obscure

fuscous; thorax transverse, the sides straight at the base but rounded from the middle to the apex, the

anterior angles mucronate, the surface sparingly punctured ; elytra deeply punctured, the punctures mostly

arranged in single rows but here and there geminate, the interstices somewhat swollen, costate at the

apex and at the sides, the metallic-green basal band strongly oblique or rounded on its hinder edge, the

posterior spot not extending to either margin; underside and legs entirely fulvous.

Hab. Mexico, Tapachula in Chiapas (Hége).

Similar in coloration and pattern to C. ancora &c., but differing from these in the

coloration of the antenne. The elytra are coarsely and more sparsely punctured than

in C. ancora, with the interstices more or less swollen; in the female (which is much

larger than the same sex of C. ancora) the interstices are strongly costate at the sides,

and the punctures are also more distinctly geminate. In one specimen the fifth to the

eighth joints of the antenne are fuscous; in the variety the metallic-green band is

united with the posterior spot on the disc.

XANTHONIA (p. 164).

Xanthonia marmorata (p. 165).

'To the localities given, add :—Mexico, Ventanas in Durango, Zacualtipan in Hidalgo

(Hoge), Amula and Chilpancingo in Guerrero (H. H. Smith); Panama, Pefia Blanca

(Champion).

The specimens lately obtained at the above localities vary considerably in the extent

of their markings and also in size and sculpture: in some examples the elytral punc-

tuation is irregular, in others it is arranged in rows and the interstices are finely

costate, this latter peculiarity being probably sexual. Of the light fulvous variety

many additional specimens have also been received. It is not impossible that

X. marmorata may ultimately prove to be a variety of X. decemnotata (Say) or of some

other described species. In a few specimens from Chilpancingo the elytral spots form

irregular patches.

THOOTES. (‘To follow the genus Xanthonia, p. 166.)

’ Body oblong-ovate, glabrous; eyes entire; antenne gradually thickened ; thorax transverse, flattened on the

disc, with a distinct lateral margin; elytra punctured in rows; legs slender, the femora unarmed; the

first joint of the posterior tarsi as long as the following two joints united; claws appendiculate ; pro-

sternum strongly narrowed between the coxe, its base truncate; the anterior margin of the prothoracic

episterna concave.

232 PHYTOPHAGA.—SUPPLEMENT.

The Mexican insect for which this new generic name is proposed has the general

appearance of a Xanthonia, from which it differs in the thorax having a very distinct

lateral margin and a glabrous upper surface; the prosternum also is much more

strongly constricted at the middle than it is in Xanthonia.

1. Thootes glabratus.

Fulvous ; the head and thorax closely punctured ; elytra metallic blue, strongly punctate-striate.

Var, Elytra fulvous with a more or less distinct bluish gloss on the disc, or entirely fulvous.

Length 1-13 line.

d. Head distinctly but not very closely punctured, fulvous; palpi flavous, the terminal joint thickened ;

antenne two-thirds the length of the body, fulvous, the terminal joints gradually but rather strongly

thickened, the third and fourth equal, the following joints slightly longer; thorax about one half broader

than Jong, the sides strongly rounded, the disc with a shallow transverse depression at the middle, the

surface strongly and closely punctured, fulvous ; scutellum small, obscure fulvous; elytra much wider at

the base than the thorax, the shoulders prominent’ and raised, the surface dark metallic blue (the

shoulders and apex sometimes fulvous), the punctures strong, arranged in regular but not very close rows,

those near the apex more distantly placed; underside obscure piceous ; legs flavous or fulvous.

Hab. Mexico, Zacualtipan in Hidalgo (Hége).

I have taken a male specimen with blue elytra for the type; the females are

larger, more flattened and widened posteriorly, and have much shorter and thinner

antenne.

In this insect the thorax is transversely sulcate on the middle of the disc, while in

Xanthonia it is sulcate in front.

FIDIA (p. 166).

Fidia albovittata (p. 167). |

To the localities given, add :—Mexico, Atoyac in Vera Cruz (H. H. Smith), Frontera

11. Fidia tibialis.

Obscure eneous, finely pubescent, the tibie and tarsi fulvous; thorax very finely and closely punctured;

elytra subquadrate, closely punctured and pubescent, the interstices at the sides finely transversely

rugose.

Length 13 line.

Head closely punctured and pubescent; eyes widely separated, entire; antennz extending only to the base of

the elytra, black, the lower joints piceous at the base, the terminal joints thickened; thorax somewhat

depressed, subcylindrical, narrowed posteriorly and at the apex, without distinct lateral margin, the disc

closely punctured, clothed with fine greyish pubescence; scutellum thickly pubescent; elytra punctured

in close irregular rows near the suture and clothed with rather long whitish pubescence, the sides finely

wrinkled ; femora unarmed, black; tibiee and tarsi fulvous, the latter darker at the base of each joint ;

underside closely pubescent.

Hab. Mexico, Chilpancingo in Guerrero (Hdége).

A single specimen.

HABROPHORA (p. 169).

2. Habrophora viridicollis.

Dark fuscous; the antenne fulvous, the seventh and the apical two joints black; head and thorax obscure

metallic green, finely pubescent ; elytra very closely punctate-striate, each with four whitish spots ante-

riorly and an irregular dentate transverse band below the middle.

Length 23-3 lines.

Hab. Panama, Volcan de Chiriqui (Champion).

In general shape and appearance this species resembles H. maculipennis, from which

it may be at once distinguished by the metallic green head and thorax and the slightly —

different pattern of the elytra. The metallic colour is not very bright, owing to the

fine pubescence and the close punctuation; the spots and the elytral band are formed

by fine pubescence, the spots being placed before the middle obliquely, the lateral one

more elongate than the others and connected with the band at the sides, this band

being of variable width and extending across the suture.

The members of this genus resemble in shape a small Noda or Colaspis, from which

they may be known by the thickly pubescent upper surface; from Colaspis they also

differ by the thorax being without lateral teeth or distinct angles, and by the terminal

joints of the antenne being thickened. One species has been obtained in plenty in

various parts of the State of Panama; the five other members of the genus are inhabi-

tants of Tropical South America.

I refer some specimens from Southern Mexico to this species, as these have the

thorax and the apex of the elytra impunctate; in a few others, however, from the

same locality there is an extremely fine punctuation visible on the thorax, and it is

therefore possible that M. regularis, Jac., may only be a variety of MW. variabilis.

7. Metachroma longicollis.

Obscure neous, the basal joints of the antenne and the legs fulvous; head and thorax closely punctured, the

latter scarce.y broader than long; elytra obscure fulvous with a strong neous gloss, rather strongly

punctate-striate.

Length 1 line.

Of narrowly elongate shape; the head eneous, rather remotely punctured on the vertex, more closely on the

clypeus, the latter not separated from the face, its lower margin very slightly concave, the labrum and

palpi fulvous; antenne extending very little beyond the base of the elytra, black, the lower four joints

fulvous; thorax but slightly broader than long, the sides rounded, slightly subangulate at the middle, the

anterior angles not or scarcely produced, the surface rather closely and strongly punctured, a little more

sparsely on the disc, the latter with a narrow longitudinal smooth space in the middle; elytra obscure

fulvous with a metallic eneous gloss, without any basal depression, the punctures rather strong and very

regularly placed, gradually diminishing towards the apex, the interstices flat and impunctate; underside

eneous, coarsely punctured; legs fulvous, the femora with a slight seneous gloss.

Hab. Mexico, San Juan Bautista in Tabasco (Hége); Guaremaua, San Gerdénimo

Of this very distinct but typical species only a single specimen was obtained by

Herr Hoge, two others by Mr. Champion. These latter are rather smaller, and have

the elytra of a more decided eneous colour. .

8. Metachroma ornata.

Black or piceous, the basal joints of the antenne and the legs fulvous; above fulvous, the head with one, the

thorax with two black spots; elytra strongly punctate-striate, the apex nearly impunctate, the disc with

an irregularly shaped subquadrate black patch.

Length 13 line.

Head rather closely and finely punctured, the vertex with a central black spot, the clypeus not separated from

the face, finely rugose ; labrum fulvous ; eyes deeply notched; antenne black, the lower six joints fulvous ;

thorax transverse, the sides strongly rounded, the surface scarcely perceptibly punctured, fulvous, a large

transverse slightly sinuate black spot on either side; scutellum fulvous; elytra pale fulvous, deeply punc-

tate-striate, the humeral interstice convex and extending obliquely to the sides, the other interstices flat.

and impunctate, the disc with a large subquadrate black patch (commencing below the base and extending

beyond the middle, and with all its margins concave, the lateral ones deeply so), which extends upwards

along the suture to the scutellum, and laterally in a narrow stripe to the shoulders, and is interrupted

in the middle on either side of the suture by a narrow stripe of the ground-colour, the sides with

two small black spots placed close to the lateral margin—one below the shoulders, the other a little

before the middle.

closely punctured; elytra flavous, strongly punctate-striate, the suture and a small spot below the

middle, black.

Length 23 lines.

Head finely and closely punctured on the vertex, the latter stained with piceous at the sides ; the clypeus mor

strongly and remotely punctured, its lower margin moderately strongly emarginate ; labrum fulvous ;

mandibles black; antennz with the lower six joints fulvous, the others black; thorax transverse, the sides

strongly rounded, the anterior angles dentiform, the surface very closely punctured, the punctures more

distinct at the sides than on the disc, the latter fulvous, with two elongate, rather distantly placed, black

spots; scutellum piceous; elytra flavous, very strongly, deeply, and regularly punctate-striate, the punc-

tures piceous in colour and distinct to the apex, the interstices minutely punctured, and at the sides

rather strongly costate, the suture and a small spot on the fifth interstice below the middle black ;

underside black; legs fulvous.

Hab. Mexico, Vera Cruz (Hége).

10. Metachroma quadrimaculata.

Fulvous, the antenns (the lower four joints excepted) black; thorax very finely punctured, with four black

spots, placed transversely ; elytra rather finely punctate-striate, the sutural and lateral margins, an oblique

stripe at the shoulder, and another near the apex, black.

Length 13 line.

Head with a black spot in the middle, rather coarsely and closely punctured on the vertex, the punctures some-

what elongate, the clypeus strongly and irregularly punctured ; antennx proportionately slender, black,

the lower four or five joints pale fulvous; thorax of the same shape as in M. ornata, very finely and

remotely punctured, the dise with four elongate equidistant black spots; scutellum with a few fine

punctures; elytra more finely punctured than in M. ornata, with a distinct lateral depression below the

base, the punctures becoming indistinct towards the apex, each elytron with an oblique short stripe

extending from the shoulder towards the middle, and another (longer or shorter) spot or stripe below the

middle, the suture and lateral margin (narrowly) black, the sutural stripe in some specimens being widened

into a spot below the scutellum; underside and legs fulvous.

The specimens from Sonora differ from all those from the cther localities in having

the oblique lateral grooves which separate the clypeus from the face obsolete, and it is

possible that they represent a closely allied species; but in the absence of other marks

of distinction, it is not advisable to separate these forms.

6. Myochrous carinatus.

Obscure sneous, clothed with yellow scales; the basal five joints of the antenne fulvous; the head with two

oblique ridges on the vertex; the thorax with three lateral teeth; elytra rather finely punctate-striate ;

anterior tibie distinctly, the posterior femora obsoletely, toothed.

Length 2-23 lines.

Hab. Mexico, Toxpam (Sallé), Teapa and San Juan Bautista in Tabasco (H. #.

Smith, Hoge).

M. carinatus differs from all the other species of the genus known to me by the more

or less distinct oblique ridges on the vertex of the head. The entire upper surface is,

as usual, covered with thick yellowish scales, which often obscure the punctuation; the

labrum and the basal five joints of the antenne are fulvous; the thorax is about as

broad as long, but the teeth at the sides are much more distantly placed than they are

in M. melancholicus.

TYPOPHORUS (p. 177).

2(a). Typophorus interstitialis.

Bluish-black, the basal six joints of the antenne fulvous; thorax strongly rugosely punctured; elytra with a

large pale red basal spot, strongly punctate-striate, the interstices finely punctured.

Length 3 lines.

Hab. Mexico, Iguala in Guerrero (Hége).

The strongly, semirugosely, punctured head and thorax and the finely punctured

elytral interstices distinguish this species from all others of the genus known to me.

The red basal spot extends nearly to the middle, but not quite to the sutural margin

of the elytra, and its posterior edge is strongly oblique; the elytra have no basal

transverse depression, and their punctured striz are visible to the apex. The femora

are armed with a minute tooth. A single specimen. |

Typophorus chalceus (p. 179).

To the Mexican localities given, add:—Acapulco in Guerrero, Tapachula in Chiapas

Very variable in size and punctuation, as well as in colour. T. viridicyanea (Crotch)

seems to me to be only a blue variety of this species ; if so, Lefévre’s name cannot stand.

Numerous specimens were obtained by Herr Hoge during his second expedition.

Variable in size, and occasionally also in the colour of the legs, which in some

much longer antenne, these organs extending considerably beyond the middle of the

elytra.

Dark or pale fulvous, the sixth to the tenth joints of the antenne black; thorax obsoletely punctured ; elytra

strongly punctate-striate anteriorly, much more finely so posteriorly, each with two spots at the base, and

a larger one on the disc, obscure piceous; apices of the femora and the tibie black.

Var. Entirely fulvous.

Length 14 line.

Head nearly impunctate, smooth; the clypeus not separated from the face, but forming a plane surface; the

ocular sulci deep; antenne black, the lower five joints and the apical one fulvous ; thorax rather broad

and not very convex, the sides deflexed, the lateral margin nearly straight, the surface with a few fine

irregularly distributed punctures; elytra with a very obsolete depression below the base, strongly

punctate-striate anteriorly, the punctures nearly obsolete on the apical portion, each elytron with a small

spot on the shoulder, another near the scutellum, and a larger more elongate one on the middle of the

disc ; legs and underside fulvous, the knees and the apices of the tibiw more or less black.

apparently differs from it in the colour of the antenne, the entirely smooth head

without transverse groove, the finely punctured thorax, and the more strongly punctate

elytra, as well as in the colour of the legs. Some of the specimens are pale fulvous,

rather broader in shape, and more finely punctured.

This species agrees with Typophorus in having broad ocular sulci, and with Paria in

the absence of any grooves on the head.

14. Typophorus limbata.

Greenish-black, the lower five joints of the antennz pale fulvous; head impunctate; thorax extremely finely

punctured ; elytra very finely punctate-striate, the punctures obsolete below the middle, the disc greenish-

black, the sides broadly reddish-fulvous.

Length 3 lines,

Hab. Guatemata (coll. Jacoby).

Of this very distinctly marked species I have received a single specimen from the

Stuttgart Museum. The impunctate head, scarcely perceptibly punctured thorax, and

very finely punctured elytra, as well as the peculiar coloration of the latter, will help

to distinguish 7. limbata. The fulvous colour of the sides of the elytra gradually

extends inwards towards the apex, the greenish sutural portion terminating in a point.

The femora have a small tooth.

PARIA (p. 182).

Paria nigritarsus (p. 184).

To the locality given, add :—Panama, Bugaba in Chiriqui (Champion).

Some differences which I attribute to local variation are to be found in the Chiriqui

specimens, these being rather smaller and having neither the suture nor the tarsi

black; in one of these examples, however, the tarsi are piceous.

6. Paria picta.

Fulvous, a spot on the head, three spots on the thorax, and two on the elytra, as well as the knees, black ;

thorax nearly impunctate; elytra with some strong punctures anteriorly, scarcely punctured posteriorly.

Length 1 line.

Head impunctate, the clypeus not separated from the face, the ocular grooves deep, the vertex with an elongate,

posteriorly widened, spot; antennz: fulvous, each joint fuscous at its apex; thorax with a few very fine

punctures, fulvous, the margins darker, the disc with three black spots placed transversely, of which the

middle one is more elongate than the others; elytra with a slight depression below the base, the punctured

strie rather deep anteriorly, but diminishing gradually and scarcely visible near the apex, a short black

streak at the centre of the base, and a longer one (widened anteriorly) below the middle; beneath fulvous,

the apex of the femora and the base of the tibise black.

Hab. British Honpuras, R. Sarstoon (Blancaneauz).

In one of the specimens obtained the lateral margins of the elytra and the sides of

the breast are also black.

PARIA.—PHANATA., 239

7. Paria binotata.

Pale fulvous, the last five joints of the antennx piceous; thorax finely but distinctly punctured; elytra finely

punctate-striate, the punctures indistinct near the apex, a short elongate spot near the base, and a more

rounded one at the middle, black.

Length 13 line.

Head impunctate on the vertex; the clypeus with a few fine punctures, not separated from the face; antennz

with the lower six joints fulvous, the others piceous or black ; thorax much broader than long, the sides

rather strongly deflexed, the surface not very closely but distinctly punctured ; scutellum broader than

long; elytra not visibly depressed below the base, more strongly punctured than the thorax, the punctures

becoming almost obsolete towards the apex.

Hab. Mzxico, Ventanas in Durango, Tupataro in Guanajuato (Hége).

This species, of which more than a dozen examples were obtained, agrees very nearly

with the description of P. le@vicollis, Crotch; this latter, however, is said to have the

thorax impunctate. The basal spot on the elytra is elongate, and placed between the

fourth and fifth strie, the other being round, and situated a little nearer the lateral

margin. No varieties are to be found amongst the specimens.

—

PHANZETA (p. 185).

2. Phansta (?) strigicollis.

Metallic greenish, zneous, or bluish; the basal joints of the antenne and the base of the femora fulvous;

thorax closely strigose-punctate ; elytra strongly and closely punctate-striate, the sides with a longitudinal

costa near the margin,

Length 13-12 line.

Head strongly punctured, the interspaces finely granulate; eyes notched at their inner margin ; antenne with

the terminal five joints strongly thickened, black, the lower six joints fulvous; thorax transversely

convex, twice as broad as long, the sides straight at the base, strongly rounded in front, the posterior

angles produced into a point, the surface crowded with elongate deep punctures which assume the shape

of strigee at the sides; elytra not wider at the base than the thorax, convex, subcylindrical, the punc-

tuation stronger than that of the thorax, and placed in close rows, the interstices scarcely perceptibly

punctured, the sides with a narrow but acute ridge extending from the shoulder to the apex; underside

ereenish-black, the breast metallic green; legs variable in colour—greenish-black with the base of the

femora fulvous, or fulvous with black tarsi; the anterior margin of the prothoracic episterna strongly

convex ; prosternum longer than broad, widened at the apex.

Hab. Muxtico, Puebla (Sallé), Tacambaro in Michoacan, Tonila in Colima, Acapulco

in Guerrero, Yautepec and Cuernavaca in Morelos (Hége).

This insect bears a most striking resemblance in colour, shape, and sculpture to

Spintherophyta thoracica (=cyanea, Lefévre); it can scarcely be distinguished from

that species without an examination of the anterior margin of the prothoracic episterna,

this being straight in Spintherophyta, and strongly convex in P. strigicollis. For this

reason I have placed the species in Phaneta, notwithstanding its somewhat different

general appearance. The colour of the elytra varies from dark to lighter blue and from

green to zneous.

240 PHYTOPHAGA.—SUPPLEMENT.

3. Phaneta (?) chrysodinoides.

Blackish, above metallic dark blue or obscure wneous; the base of the antenne, the apex of the tibia, and the

tarsi more or less fulvous ; thorax closely punctured, the punctures partly oblong ; elytra closely punctate-

striate; the apex of the anterior tibie produced into a tooth.

Var. Legs entirely fulvous.

Length 13 line.

Head rather closely and strongly punctured, the clypeus not separated from the face, the eyes notched at their

inner margin; labrum fulvous, the disc piceous; antenne extending to the middle of the elytra, the

terminal joints gradually thickened, the lower six joints fulvous, the basal one stained with piceous above,

the third and fourth joints equal; thorax transversely convex, narrowed in front, the sides rounded, the

anterior angles acute, the surface rather closely punctured, the punctures somewhat elongate in shape at

the sides; scutellum broad, smooth ; elytra subcylindrical, convex, without basal depression, more strongly

punctured than the thorax, the punctures arranged in close rows ; legs robust, the apices of the tibiz and

the tarsi fulvous; the anterior tibie produced into an acute tooth at the apex; the anterior margin of the

prothoracic episterna slightly convex.

Hab. Mexico, Pinos Altos in Chihuahua (Buchan-Hepburn), Ventanas, Refugio, and

Ciudad in Durango (Hoge, Forrer).

This insect has the appearance of a species of Chrysodina. It possesses the principal

structural characters of Phaneta; but is somewhat doubtfully included by me in that

genus, owing to the more transversely-shaped thorax, the much less convex anterior

margin of the prothoracic episterna, and the dentate anterior tibiae. M. Lefévre is of

opinion that the species is best placed in Phaneta. The breast has generally a metallic

greenish tint, but the rest of the underside is nearly black.

COLASPOIDES (p. 185).

Colaspoides chiriquensis (p. 186).

To the Panama locality given, add :—Bugaba (Champion).

This species proves to be very variable in colour, and amongst the numerous

specimens since received the following varieties are to be found :—

a. Above bright cupreous or aureous.

b. The head and thorax aureous, the elytra dark blue with the apical margin aureous.

c. Above entirely dark blue, the legs piceous.

These additional examples vary in size from 24 to 3 lines. The dark blue form

might easily be mistaken for C. wnicolor, Jac.; but in that species the general shape is

narrower, the head has a triangular groove, the antenne have only the basal joints

fulvous, and the thorax is strongly narrowed at the sides and more punctured.

4(a). Colaspoides fulgurans.

Coiaspoides fulgurans, Lefévre, Revue et Mag. Zool. 1875, p. 188°.

Hab. Costa Rica (Van Patten).—Braziu1.

Two Costa Rican specimens before me agree entirely with a Brazilian one named by

COLASPOIDES.—PHADON. 241

Lefévre, and contained in my collection. The entire upper surface of C. fulgurans is

bright metallic aureous; the underside and legs are metallic violaceous blue, and the

tarsi are fulvous.

PHZEDON (p. 188).

5. Pheedon fusculum.

Ovate, obscure fusco-zneous, the basal joints of the antenn# and (sometimes) the head and thorax obscure

fulvous; thorax irregularly and finely punctured; elytra finely punctate-striate, the interstices very

finely coriaceous.

Length 12 line. .

Head finely and somewhat closely punctured, the clypeus separated from the face by a narrow triangular

groove; antenne extending to the base of the elytra, fulvous, the terminal five joints black, transverse ;

thorax more than twice as broad as long, the sides straight at the base, slightly rounded anteriorly, the

surface irregularly and very finely punctured, the punctures of elongate shape and closely placed along

the posterior margin; scutellum impunctate; elytra nearly parallel, generally darker in colour than the

thorax, fusco-seneous, the shoulders not prominent, but marked within by a rather distinct depression, the

punctured striz very distinct and regular, the interstices finely coriaceous; underside obscure fulvous

with a slight seneous gloss.

Hab. Mexico, Huetamo and Tacambaro in Michoacan, Acapulco in Guerrero (Hége).

P. fusculum may be principally distinguished by its obscure fulvous head and thorax

and eneous or fuscous elytra; the basal joints of the antenne are also obscure fulvous.

6. Phedon varicolor.

Subelongate, metallic green, the antenne and tarsi black; thorax cupreous (or green), closely and finely punc-

tured ; elytra finely punctate-striate, the interstices very finely transversely rugose.

Length 13-2 lines.

Head greenish or cupreous, finely and rather closely punctured; the antenne black, extending to the base of

the elytra; thorax scarcely widened at the middle, transverse, the sides straight at the base, rounded in

front, the surface punctured like that of the head, not more strongly so at the sides than at the middle ;

scutellum cupreous or green; elytra rather elongate in shape, the punctured striw fine, the punctures

themselves closely placed, the interstices very finely transversely strigose or wrinkled.

Hab. Mexico, near the city (1. H. Smith).

Two examples. More elongate and less convex in shape than its allies from our

region, and principally separated by the evenly distributed punctuation of the thorax,

the finely transversely strigose elytral interstices, and the bright green metallic colour ;

one specimen has the head and thorax cupreous. In these particulars P. varicolor

differs from any of its North-American congeners.

7. Pheedon seticornis.

Obscure greenish-black, the antennze and tarsi black; head and thorax greenish-cupreous, closely punctured ;

elytra obscure violaceous, finely punctate-striate.

Length 13 line.

Of ovate, convex shape; the head finely and rather closely punctured, without distinct depression between the

eyes, obscure greenish-cupreous, semiopaque ; antenne black, the terminal joints gradually widened and

strongly transverse, each joint furnished with a few erect hairs; thorax nearly three times as broad as

BIOL. CENTR.-AMER., Coleopt., Vol. VI. Pt. 1, Suppl., February 1891. 91

242 PHYTOPHAGA.—SUPPLEMENT.

long, distinctly widened at the middle, the sides but slightly rounded at the base, more strongly so towards

the apex, the surface closely and rather strongly but somewhat irregularly punctured, the disc reddish, the

sides greenish-cupreous, semiopaque ; scutellum metallic greenish ; elytra narrowed at the base and apex,

fusco-violaceous, finely punctate-striate, the interstices extremely finely coriaceous.

Hab. Mzxico, Ventanas in Durango (orrer).

More convex than P. varicolor, the thorax more transverse, the elytra differently

punctured. A single specimen.

8. Phedon multipunctatus.

Dark eneous, the basal joints of the antennz, the lower part of the head, the sides of the thorax, the legs,

and the last two abdominal segments flavous; thorax impunctate; elytra strongly and very closely

punctured.

Length 13 line.

Of ovate, feebly convex shape; the head with a few minute punctures, rather deeply depressed between the

eyes, the vertex dark seneous, the lower portion, labrum, and palpi flavous; antenns scarcely extending

to the base of the thorax, the lower six joints flavous, the others black and strongly transverse; thorax

transverse, the sides nearly straight, narrowed in front, the disc impunctate, blackish-eneous, the lateral

portion with a few fine punctures, flavous, and with an obsolete fovea near the margin ; elytra widened

towards the middle, strongly and extremely closely punctured in rows, with three or four indistinct

longitudinal raised lines, the shoulders rather prominent; legs and the last two abdominal segments

flavous; prosternum narrowed between the coxe.

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

A single specimen. The comparatively small size, the feebly convex shape, and the

very close elytral punctuation separate P. multipunctatus from several somewhat

similarly coloured species found in the more southern parts of America.

14. Plagiodera bis-tripunctata. (Tab. XLI. fig. 1.)

Plagiodera bis-tripunctata, Duvivier, Comptes Rend. Soc. Ent. Belg. 1885, p. exviil!,

Hab. Panama, Volcan de Chiriqui (Champion), Chiriqui’.

Of this comparatively large-sized species very many specimens were obtained by

Mr. Champion. The head has one spot, the thorax has seven, and the elytra have

three spots, those on the latter placed in a triangle below the base; the general

ground-colour is fulvous; the antenne and legs are partly or entirely black. In some

specimens the thoracic spots are more or less confluent; in others the suture has a

short black streak anteriorly. Common on bushes on the savanas in Chiriqui at an

elevation of 4000 feet (Champion).

15. Plagiodera viridimaculata. (Tab. XLI. fig. 2.) .

Testaceous, the apical joints of the antenne and the tarsi black ; thorax impunctate ; elytra closely punctured,

each with six metallic green round spots (1, 2, 2, 1).

Length 2 lines.

(3)

PLAGIODERA. 243

Head impunctate ; the basal five joints of the antenne fulvous, the other joints black, strongly transverse, the

first joint thickened, the second elongate, the following three joints gradually shortened ; thorax about

three times as broad as long, slightly longer at the sides than at the middle, the lateral margins but little

rounded, the disc impunctate; scutellum obscure piceous; elytra rounded, convex, rather strongly and

closely punctured, the punctures arranged in very irregular rows, which are here and there separated by

smooth longitudinal spaces, the lateral margins thickened and accompanied by an impressed line, which is

very strongly marked towards the base, the suture very narrowly and six round spots on each elytron

metallic green, the spots placed thus—one at the shoulder, two obliquely before, two others (more

transversely) below the middle, and one near the apex; underside darker than above; the knees and

tarsi black.

Hab. Panama, Volcan de Chiriqui (Champion).

A single specimen.

16. Plagiodera obscuripennis.

Subrotundate, convex, fulvous, the apical joints of the antenne black; thorax nearly impunctate; elytra

blackish, finely and subremotely punctured, the lateral margins and the epipleure fulvous.

Length 23 lines. ;

Head fulvous, entirely impunctate; the antenne short, the last six joints strongly transverse, black, the others

fulvous; thorax strongly transverse, the sides straight, greatly narrowed in front, the posterior margin

oblique on each side, straight in front of the scutellum, the angles obtuse, the surface impunctate or with

a few minute punctures; scutellum fulvous, its apex broadly rounded ; elytra blackish, with a faint bluish

gloss, the shoulders slightly raised, the surface finely but not closely punctured, the punctures arranged

partly in double rows near the suture, the extreme lateral margins and the epipleure fulvous; underside

and legs fulvous, impunctate.

Hab. Mexico, Acapulco in Guerrero (Hége).

The nearly impunctate thorax, the blackish elytra, and the extremely narrow fulvous

margin of the latter principally distinguish P. obscuripennis.

17. Plagiodera arizone.

Plagiodera arizone, Crotch, Proc. Ac. Phil. 1873, p. 53°.

Hab. Norra America, Arizona !.—Mexico, Northern Sonora (Morrison).

The specimens received from Mr. Morrison, and named by him P. arizona, agree

with the short description given by Crotch, who says that the species is extremely near

P. californica, Rogers; this latter, however, belongs to the genus Lina, and differs

totally in colour from the present insect, being entirely of a blackish-green hue. In

P. arizone the head, thorax, underside (with the exception of the breast, which is

dark bluish), and legs are fulvous, and the elytra are obscure greenish or bluish; the

first four joints of the anteune are fulvous, the rest black; the thorax is finely and

very irregularly punctured (sometimes almost impunctate on the disc); the elytra

may be described as rugosely punctate, the interstices being everywhere transversely

wrinkled. PP. arizone is omitted from Gemminger and Harold’s Catalogue, and also

from that of Duvivier.

CALLIGRAPHA. 245

The specimens from the above localities differ from the type in the greenish-eneous

colour of the elytral markings; the markings themselves also vary somewhat in shape,

thus, the sutural band is interrupted at a little distance from the base, and the small spots

below the middle are often more or less confluent; the antenne and legs in all these

examples are, however, fulvous or piceous as in the type. C. suffriani may perhaps be

most readily identified by the shape of the elongate mark at the shoulder, this being

usually divided into three branches—one on the inner side and two behind.

Calligrapha suboculata (p. 200).

12 (a). Calligrapha fulvitarsis. (Tab. XLI. fig. 3.)

Greenish-sneous, the antenne, labrum, and tarsi dark fulvous; thorax sparingly punctured ; elytra flavous, a

broad sutural stripe with three lateral projections, an elongate shoulder-spot, a round spot near the

scutellum, and nine or ten small spots on the disc, greenish-seneous.

Length 4 lines.

Head finely punctured; antenne entirely fulvous, the terminal joints but gradually and slightly thickened ;

thorax twice as broad as long, scarcely widened at the middle, the sides straight at the base, very slightly

rounded in front, the disc finely and sparingly, the sides more deeply, but not closely, punctured; elytra

punctate-striate near the suture, the rest of the surface irregularly punctured, with a broad sutural stripe—

narrowed towards the base, and with a short branch on each side, obliquely angulate below this branch,

then narrowing, and below the middle suddenly widened again—and numerous spots—an elongate one,

pointed behind, placed on the shoulder, a round one near the scutellum, three small ones placed obliquely

before and two others below the middle, and a larger spot (sometimes divided) and two smaller ones

near the apex, and, in addition to these, one joins the sutural stripe near the apex, and a thin elongate

spot is placed near the lateral margin at the middle, all these markings being generally surrounded by

a paler yellowish margin ; the apices of the tibiz and the tarsi fulvous or obscure fulvous.

Hab. Panama, Bugaba (Champion).

Numerous examples. C. fulvitarsis is very closely allied to C. suboculata, C. ramu-

lifera, and several other species, but shows constant differences in the shape of the sutural

stripe of the elytra, and in the colour of the antenne and tarsi. The sutural stripe is

obliquely angulate below the base, the angle pointing downwards, this character being

constant in all the specimens obtained. The markings will be best understood from

our figure.

37. Calligrapha femorata. (Tab. XLI. fig. 4.)

Dark greenish-sneous, the labrum, antenne, and legs fulvous ; thorax with the sides straight ; elytra testaceous,

a broad sutural stripe (connected with a stripe at the middle), the lateral margins, a broad irregular mark

at the shoulder, and five spots below the middle brownish-sencous ; femora with a blackish spot at the

base.

Length 33 lines.

Head moderately closely punctured, the labrum and mandibles fulvous, their extreme apex black ; antennze

rather long, entirely fulvous, the terminal six joints gradually dilated ; thorax more than twice as broad

as long, the sides almost straight, the anterior margin strongly concave, the disc sparingly, the sides deeply

and more closely punctured ; elytra only punctured round the dark markings, the testaceous portion

impunctate, the sutural band joined to a curved stripe at the middle, and widened into a spot near the

apex, the lateral margins also brownish-eneous (more broadly so near the middle), the shoulder-spot broad,

extending downwards, and joined to the sutural stripe near the base and at the middle, its outer margin

biangulate, two small spots placed obliquely near the sutural stripe, a larger one below the middle connected

with the lateral stripe, a similar spot near the apex, and also joined to the lateral stripe, and a transversely-

shaped spot between these brownish-eneous ; legs bright fulvous, the base of the femora with a large

greenish-black spot.

Hab. Mexico, Xautipa in Guerrero (H. H. Smith).

A single specimen. The colour of the labrum, antenne, and legs, and the straight

sides of the thorax, in connection with the dark lateral margin of the elytra, separate

C. femorata from any of its allies.

38. Calligrapha marginipennis. (Tab. XLI. fig. 5.)

Greenish-sneous, the basal joints of the antenne fulvous; thorax foveolate-punctate at the sides, sparingly

punctured on the disc; elytra testaceous, the suture, lateral margin, an elongate broad spot at the shoulder,

and nine or more smaller spots at the sides, greenish-aneous.

Var. The antenne and legs obscure fulvous.

Length 34-43 lines.

Hab. Mexico, Acapulco in Guerrero (Hége); Guatemata (coll. Jacoby).

C. marginipennis resembles in the pattern of its elytra C. geographica, C. consputa,

and several other species; but differs from all these in having the sutural stripe entirely

uninterrupted, of equal width, and split or divided near the base, and in having a

similar narrow stripe accompanying the lateral margin for its entire length. The

usual mark at the shoulder is broad, and extends nearly to the middle of the elytra, its

posterior edge being divided into two points, the outer one of which curves outwards ;

a large V-shaped or angulated spot is placed close to the suture below the middle, and

the rest of the disc is occupied by nine or ten irregular spots; the lateral and sutural

stripes are joined at the apex. A Guatemalan specimen received from the Stuttgart

Museum is much larger, and has many more spots posteriorly.

It is somewhat doubtful whether the Mexican examples are really conspecific with

Z. conjuncta (Rogers). The elytral markings of the latter, as figured by the author,

are not like those of our specimens, but agree exactly in pattern with Z. tortuosa

(Rogers) ; the design of the thorax, however, resembles that of the Mexican insect, the

thorax in Z. tortuosa being unicolorous.

Zygogramma morbillosa (p. 216).

To the Mexican localities given, add :—Chilpancingo in Guerrero (H. H. Smith).

The specimens obtained by Mr. Smith vary so much amongst themselves, and also

from the type, in regard to the elytral design, that it is impossible to come toa decided

opinion as to whether they really belong to one species or not ; the shape and position

of the spots cannot be described in words, as they are frequently asymmetrical.

30. Zygogramma, fasciatipennis. (Tab. XLI. fig. 6.)

Obscure greenish-sneous; the head and legs fulyous; thorax closely punctured, flavous, the posterior portion

fulvous; elytra strongly punctured, flavous, a sutural stripe (divided anteriorly), two stripes on the disc,

joined at the apex, and the posterior portion of the lateral margin, piceous.

Length 34 lines.

Hab. Mexico, Northern Sonora (Morrison).

This insect resembles Z. conjuncta (Rogers), from which it differs in the strongly

punctured elytra, and in their fulvous epipleure and dark posterior portion of the

lateral margin; Z. exclamationis (Fabr.) and several other allied species are without a

marginal stripe. ‘The elytra are entirely devoid of spots; the terminal joints of the

antenne are black (as usual) ; the head is closely, the thorax more sparingly punctured

(finely on the disc, strongly at the sides); the basal band of the thorax is much widened

inwardly and sinuate or dentate on its anterior margin, though variable in this respect ;

the elytral stripes are of almost equal width and nearly black—the discoidal ones

coalesce at the apex and are produced into a point, the outermost of the two being

slightly sinuate exteriorly—and strongly and closely punctured, the interstices more

sparingly so and somewhat convex; the underside has a more or less metallic eneous

gloss over a dark fulvous ground-colour; the claws are united at the base.

31. Zygogramma, obscuro-fasciata. (Tab. XLI. fig. 7.)

Blackish-seneous, the head, thorax, and legs fulvous ; elytra pale flavous, the suture and a broad stripe towards

the sides obscure fulvous, the disc with numerous round blackish spots.

Length 2 lines.

Hab. Mexico, Chilpancingo and Omilteme in Guerrero (H. H. Smith).

Very closely allied to Z. guttulosa and resembling it in colour, but differing thus :—.

The thorax, instead of being rather strongly punctured on the disc, is nearly impunc-

tate or very sparingly punctured ; and the elytra have an obscure broad fulvous stripe

towards the sides and fewer spots, these being sometimes confluent and forming elongate

marks here and there (in Z. guttulosa the entire disc is closely spotted and the fulvous

stripe is absent). About thirty specimens were obtained.

32. Zygogramma durangoensis. (Tab. XLI. fig. 8.)

Dark fulvous, the terminal joints of the antenne black ; thorax foveolate-punctate at the sides; elytra flavous, |

a sutural and a marginal stripe, three spots placed triangularly at the base, a broad curved stripe extend-

ing from the shoulder to below the middle, and two rows of smaller spots at the sides, as well as several

other spots near the suture, fulvous.

Length 3-34 lines. ,

Head subremotely punctured; antenne fulvous, the terminal five joints strongly thickened, black ; thorax

three times as broad as long, slightly widened at the middle, the sides nearly straight, strongly produced

- and rounded in front, the surface irregularly but not very closely punctured, the interspaces somewhat

swollen, the sides foveolate and closely punctured ; elytra punctate-striate near the suture and lateral

margins, the disc irregularly punctured, the sutural stripe suddenly narrowed below the base, straight

and of equal width posteriorly, the marginal stripe extending from the middle to the apex, the stripe at

the shoulder broad, strongly curved, and reaching to below the middle but not to the suture, the three

larger spots triangularly placed near the scutellum, a row of punctures running parallel with the suture

posteriorly, and two rows of smaller punctures (unequal in size and numbers) running parallel to the

lateral margin; underside and legs dark fulvous, the breast with a more or less distinct «neous gloss.

Hab. Muxtco, Ventanas in Durango (Hége).

In its markings and general colour Z. durangoensis somewhat resembles Z. lemur,

but differs from it in having the lateral portion of the thorax rather strongly produced

in front, causing the anterior margin to be deeply concave behind the eyes; the three

spots near the scutellum, the broad curved humeral stripe, and the even sutural stripe

further distinguish the species. Several specimens.

33. Zygogramma maculicollis. (Tab. XLI. fig. 9.)

Fulvous, the terminal joints of the antenne black; the head with a fulvous spot; thorax flavous, the sides

and a'‘V-shaped mark on the disc fulvous; elytra testaceous, marked with numerous black spots, the

suture and a broad stripe at the sides, fulvous.

Length 3-34 lines.

Head nearly impunctate, dark fulvous, the middle flavous ; antenne dark fulvous, the terminal five or six joints

black, dilated ; thorax about twice as broad as long, the sides rather rounded, but slightly produced

anteriorly, the surface strongly punctured towards the sides and along the basal margin, the disc nearly

impunctate, flavous, the lateral portion partly and a V-shaped mark on the disc dark fulvous; elytra very

strongly and irregularly punctured, with a deep and regular row of punctures accompanying the lateral

margin, and a shallower row of punctures near the suture, the latter and a broad stripe towards the sides,

extending from the base to near the apex, dark fulvous, the rest of the disc and the lateral portion pale

testaceous, closely marked with small blackish spots of irregular shape and size, the epipleurs testaceous ;

underside and legs dark fulvous.

Hab. Mxxico, Durango city (Hége), Soledad in Guerrero (H. H. Smith).

I cannot recognize in this species Z. pustulosa or Z. guttaticollis (Stal), which are

described as testaceous or eneous, with testaceous bands to the elytra, and also differ

in some other particulars; possibly St&l’s descriptions are incorrect or taken from

immature or discoloured specimens.

In one example of Z. maculicollis the sublateral stripe of the elytra joins the sutural

one at the apex.

34. Zygogramma militaris. (Tab. XLI. fig. 10.)

Dark fulvous, the apical joints of the antenne black; thorax deeply punctured at the sides ; elytra testaceous,

a sutural stripe (narrowed at the base) and a broader stripe extending from the shoulder to below the

middle dark fulvous, several spots near the scutellum, two rows of spots at the sides, and a very narrow

stripe near the lateral margin, piceous or fuscous.

Length 3 lines.

Hab. Mexico, Ventanas in Durango (Hége).

Similar in colour and markings to Z. durangoensis, and with the thorax similarly

shaped and sculptured, but differing as follows :—The elytra (instead of having three

spots placed triangularly near the scutellum) have two small spots at the base and

several spots near the suture; the broad sublateral stripe (which in Z. durangoensis

has its outer margin deeply concave) is of nearly equal width throughout, being only

slightly sinuate towards the middle; the marginal stripe is absent, but is replaced by

a very narrow brownish line which runs parallel with the epipleure. Several speci-

mens, all agreeing in the above particulars.

35. Zygogramma decempustulata. (Tab. XLI. fig. 11.)

Dark fulvous; the thorax sparingly punctured on the disc, strongly so at the sides; elytra irregularly punc-

tured, fulvous, the lateral margins, a spot placed at the middle on either side, and four irregular spots

placed longitudinally near the suture, flavous, margined with fuscous.

Length 3-33 lines.

Head subremotely punctured; antenne fulvous, the terminal five joints black; thorax fulvous, strongly

transverse, the sides considerably produced in front, the disc very finely and sparingly, the lateral portion

very deeply punctured ; elytra with a subsutural and a submarginal row of punctures, the disc irregularly

punctured, dark fulvous, the lateral margins flavous, each elytron with four irregular spots placed close to

the suture—the basal one often rounded and enclosing a round spot of the ground-colour, but sometimes

angular, the second before the middle, the third triangular in shape and placed below the middle, the

fourth near the apex, irregularly ovate, and connected with the flavous lateral margin—and a small spot

extending inwards from the flavous margin at the middle, all the spots and the margin surrounded by a

piceous or fuscous line ; the epipleurz, the underside, and legs dark fulvous.

Black; the thorax pale fulvous, the basal margin broadly marked with black, the dise impunctate ; elytra

flavous, a sutural stripe (divided anteriorly), two stripes on the disc, and the posterior portion of the

lateral margin, black.

Length 33 lines.

Head black, closely punctured near the eyes ; palpi black, the terminal joint not longer than the preceding

one; antennee black, the terminal five joints pubescent, thickened, the others shining, the four or five

basal joints obscure fulvous ; thorax about twice as broad as long, rather strongly widened at the middle,

the sides straight at the base, rounded in front, but scarcely produced at the apex, the disc with a few

minute punctures, the lateral portion and base more closely and strongly punctured, pale fualvous, the

lateral and apical margins very narrowly, the basal margin broadly black; scutellum black; elytra

punctate-striate along the inner and outer margins of the dark stripes only, for the rest irregularly

punctured, flavous, a narrow sutural stripe (divided below the base), two broader stripes on the disc

(the inner one the shortest, the outer one not extending to the apex), and the lateral margin from the

middle to the apex, black ; underside and legs black with a bluish gloss, strongly punctured.

Hab. Mexico, Durango city (Hége).

A single specimen. Evidently allied to Z. rustica (Stal), but differing in the black

palpi, the divided sutural stripe, and the colour of the lateral margin of the elytra;

the basal black band of the thorax is strongly concave on its anterior edge.

Black ; head flavous ; thorax sparingly punctured, the sides flavous ; elytra distantly striate-punctate, flavous,

each with a black subsutural and a submarginal stripe.

Var. One of the elytral stripes obsolete or entirely absent.

Length 34—4 lines.

Head with a few fine punctures, flavous; the terminal joint of the palpi scarcely shorter than the preceding

one; antenne rather slender, the terminal joints but slightly thickened, black, the basal joints stained

with flavous beneath ; thorax about twice as broad as long, the sides nearly straight, the anterior angles

not very prominent and rather blunt, the disc with some scattered punctures, black, the sides flavous ;

scutellum black ; elytra wider at the base than the thorax, parallel, each with about seven rows of fine

punctures, the fourth and fifth rows much more widely separated than the others, the disc flavous, a

narrow black slightly curved stripe placed close to the suture (not extending to the apex) and a similar

stripe occupying the space between the fifth and sixth rows of punctures, the outer stripe extending nearly

to the suture ; underside and legs black.

Hab. Panama, Volcan de Chiriqui 4000 feet ( (Champion).

More than a dozen specimens were obtained by Mr. Champion, who states that the

species inhabits the dense forest only. When the insect is alive the elytra are of a

brilliant metallic golden colour, resembling in this respect many of the Cassidide.

L. lineolata has hitherto only been recorded from the United States, but many

specimens have now been received from the Mexican localities quoted above. The

species varies in size, colour, and elytral markings. The type has the head, thorax,

and elytral markings metallic green or eneous; but some of the Mexican examples

before me have these parts fulvous. The elytra are flavous and have each four stripes,

these being interrupted at the middle and varying in length, the posterior portion of

one or the other of them being often obsolete. JZ. lineolata is smaller than L. flavi-

tarsisand L. nitidicollis, which it resembles somewhat in colour and markings; but

in these species there are only two stripes on each elytron anteriorly and three

posteriorly, which are partly connected.

Leptinotarsa signaticollis (p. 232).

To the Mexican localities given, add:—Tacambaro and Morelia in Michoacan

(Hoge), Cuernavaca in Morelos, Amula and Xucumanatlan in Guerrero (H. H. Smith).

The elytral punctuation proves to be very variable in this species, the punctures

being sometimes arranged in irregular double rows with the interstices more or less

convex, and sometimes irregularly distributed over the entire surface.

I refer all the specimens from the above-mentioned additional localities to LL. decem-

lineata, all having fulvous legs, more or less marked or spotted with black. According

to Crotch, L. multilineata (Stl) is specifically distinct ; I believe, however, that it is

only a variety of L. decemlineata. The locality “‘ Costa Rica” quoted by me at p. 233

requires confirmation. ;

18 (a). Leptinotarsa angustovittata. (Tab. XLI. fig. 15.)

Leptinotarsa undecimlineata, huj. op. (partim). '

Black; the head with two flavous spots; the thorax and elytra flavous, the former spotted with black, the

latter with eight narrow black, strongly punctured, longitudinal stripes.

Length 5-6 lines.

Hab. Muxico, Guanajuato (Sallé), Morelia and Tacambaro in Michoacan (Hége),

Xucumanatlan in Guerrero (H. H. Smith).

This insect was previously treated by me asa variety of L. undecimlineata; but as

we have now received about twenty additional specimens, all alike, I am compelled to

treat it as a distinct species. It agrees in everything with L. undecimlineata, except

that the elytra have eight very narrow black stripes, each of which is abbreviated at

a short distance before the apex ; these stripes are deeply punctured in single, some-

times in double and very closely contiguous, rows (this character separating the species

from L. undecimlineata, in which each elytron has four much broader stripes, and the

stripes singly or doubly punctured along their margins).

Both L. angustovittata and L. undecimlineata occur at Guanajuato.

middle, a number of spots beyond the middle, and the lateral margins, black.

Length 4 lines,

LEPTINOTARSA.—DORYPHORA. 255

Head sparingly punctured and very finely semirugose, the vertex with a blackish spot; antenne black, the

basal five joints fulvous; thorax three times as broad as long, widened at the middle, the anterior margin

slightly convex, the posterior margin strongly rounded, the sides slightly converging towards the apex,

the surface opaque, fulvous, finely and rather closely punctured, the interspaces exceedingly minutely

punctate or coriaceous, all the margins (or the, basal and apical ones only) very narrowly piceous ;

scutellum dark fulvous; elytra strongly convex, testaceous, their epipleure fulvous, a subsutural stripe,

two shorter stripes placed anteriorly (the outer one connected with a stripe turned obliquely upwards), a

transverse band about the middle, eight or ten spots beyond the middle, and a small spot at the shoulders,

blackish ; underside blackish-green, with the sides of the breast obscurely fulvous, sometimes paler ; legs

entirely fulvous.

Hab. Mexico, Pinos Altos in Chihuahua (Buchan-Hepburn), Ventanas in Durango

(Hége).

Like several of its congeners, L. typographica has the elytra marked with dark

stripes; these stripes, however, in the present species are confined to the anterior

portion, the posterior part being spotted—five spots running parallel with the suture,

and some others forming two additional rows on the outer portion of the disc, the spots

bounded anteriorly by a transverse band at the middle; the short stripe near the

shoulders is joined in front to the second discoidal one.

256 PHYTOPHAGA.—SUPPLEMENT.

27 (a). Doryphora stabilis. (Tab. XLI. fig. 17.)

Obscure eneous; the antenne and legs fulvous; the thorax sparingly punctured, greenish-seneous ; elytra

flavous, finely punctate-striate, the suture broadly, the lateral margins, a large transverse patch anteriorly,

connected with the sutural stripe at the middle, and an equally large subtriangular pointed patch below

the middle, brownish-seneous. ,

Length 33-4 lines.

Hab. Panama, Bugaba in Chiriqui (Champion).

D. stabilis is a comparatively small species which may be best compared with

D. chontalensis, Jac., an insect resembling it in size and, to a certain extent, in the

elytral markings. The markings, however, in D. stabilis occupy almost the entire disc,

and are interrupted only by narrow flavous stripes of the ground-colour ; the anterior

patch has the appearance of two broad elongate spots joined together and to the sutural

stripe at the middle; the posterior spot is angulate and pointed at its apex. The

underside and the femora are more or less stained with greenish-eneous; the mesosternal

process is strong and rather long, and generally fulvous in colour.

ELYTROSPHERA (p. 260).

6. Elytrosphera tibialis.

Prosicela tibialis, huj. op. p. 241.

To the Mexican locality given, add :—Chilpancingo in Guerrero (H. H. Smith).

The two specimens obtained by Mr. Smith differ considerably from the type in the

elytral pattern: the posterior black bands are broken up into stripes, and there is an

additional submarginal stripe; the posterior transverse black band is much narrower.

The posterior portion of the elytra may be described as testaceous, with three narrow

brown or black stripes, which are joined at the apex; all the femora are fulvous at the

base. In other respects the Chilpancingo specimens agree with the type.

7. Elytrosphera marginicollis. (Tab. XLI. fig. 18.)

Oblong-ovate, widened posteriorly, greenish-seneous; the basal joints of the antenne, the base of the femora,

and the apex of the tibie, more or less, fulvous; thorax minutely punctured, the lateral margins flavous ;

elytra testaceous, marked with narrow dark stripes, which are interrupted at the middle by a pale

zigzag band.

Length 4-5 lines.

Head sparingly punctured, obscure seneous or purplish; antenne more than half the length of the body, black,

the lower two joints fulvous beneath; thorax transverse, the sides rather strongly rounded and dilated

the anterior angles produced, the surface obscure seneous, here and there with a purplish tint, extremely

finely and sparingly punctured, the lateral margins rather broadly flavous, the flavous portion somewhat

swollen ; scutellum broad, impunctate, purplish or greenish; elytra widened posteriorly, finely punctured

in rather regular double rows, each elytron with a subsutural and a submarginal purplish-sneous stripe,

and about seven or eight other stripes scattered over the rest of the surface, the latter of irregular length,

joined at the base and apex, and closely placed, but interrupted at the middle by a transverse zigzag band

of the ground-colour; beneath encous with a more or less purplish gloss, the sides of the breast and the

margins of the abdominal segments testaceous or obscure testaceous.

Hab. Muxtco, Omilteme, Chilpancingo, and Xautipa, all in Guerrero (H. H. Smith).

E. marginicollis resembles somewhat in the elytral pattern L. tibialis, but differs

from that insect in the flavous thoracic margin and in the numerous elytral stripes ;

these stripes are more or less united about the middle, and form spots which limit the

pale transverse band posteriorly, this band being strongly dentate in the centre (in

E. tibialis its place is taken by small flavous spots placed much more in a line). The

posterior portion of the elytra in E. marginicollis has also a more or less developed

flavous spot on the lateral margin and a smaller spot near the apex.

8. Elytrosphera bifasciata. (Tab. XLI. fig. 19.)

Oblong-ovate, widened posteriorly, neous; the thorax opaque, impunctate; elytra semipunctate-striate, the

interstices aciculate, fulvous, a very broad transverse band at the base and a narrow one at the middle, as

well as the sutural and lateral margins, obscure aneous.

Length 443-5 lines.

Of the same shape as E. marginicollis, obscure brownish or blackish-geneous ; the head rather closely punctured

near the eyes; the antenne not extending much beyond the base of the elytra, black, the lower three

joints stained with fulvous at the apex, the terminal joints gradually but moderately thickened; thorax

more than twice as broad as long, the sides rounded and dilated towards the apex, the surface opaque,

impunctate or nearly so on the disc, the lateral portion with a few fine punctures; scutellum impunctate ;

elytra with fine rows of punctures, which are arranged somewhat in double rows, more irregularly punc-

tured towards the base, the interstices everywhere aciculate and coriaceous, fulvous, the basal portion

occupied by a broad dark eneous band (slightly produced at the suture, and not extending to the lateral

margin), and a narrow band placed at or immediately below the middle (sometimes extending to the

lateral margin, but not to the suture, sometimes not to either), the suture and the lateral margin also

eeneous ; underside and legs more or less tinged with purplish.

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

Several examples. The antenne in this species have the terminal joints more

thickened than in most of the allied forms.

9. Elytrosphera erratica, (Tab. XLI. fig. 20.)

Obscure seneous, the head, antennx, and legs fulvous; thorax strongly punctured, more or less marked with

fulyous; elytra irregularly punctured, obscure violaceous or neous, with very narrow, short, irregular,

pale flavous or whitish transverse stripes.

Length 23-3 lines.

Head fulvous, sparingly punctured, the vertex often spotted with obscure eneous ; palpi and antenne entirely

fulvous, the latter with the terminal joints gradually thickened, and the last joint distinctly longer than

broad; thorax rather more than twice as broad as long, the sides rounded, not much produced in front,

the anterior angles obtusely rounded, the surface strongly punctured laterally, much more finely and

sparsely so on the disc, the latter greenish-eneous, the sides often with a large fulvous spot, this colour

sometimes extending over the entire surface; scutellum obscure fulvous ; elytra convex, widened towards

the middle, not strongly or closely punctured—the punctures here and there arranged in rows, but for the

most part irregularly distributed,—of a very dark violaceous or seneous colour, with the following pale

flavous or whitish markings—a narrow stripe along the basal margin near the scutellum, from which a short

branch extends downwards at its outer end, a narrow stripe along the lateral margin, curving inwards before

the middle and then extending outwards again, a narrow oblique stripe on the disc before the middle, a

transverse stripe below the middle, a transverse irregular angulated stripe before the apex, a shorter one

at the apex itself, and several small spots near the shoulders.

Hab. Mexico, Chilpancingo and Omilteme in Guerrero (H. H. Smith).

The markings of the elytra are very sharply defined, delicate, and thin, and of a

somewhat opalescent or golden tint; they vary greatly, and are in some specimens

interrupted or asymmetrical, but they generally follow the shape and position described.

The colour of the legs and of the thorax and the fine elytral punctuation principally

distinguish E. erratica from several of the allied forms; the different shape of the

markings and the much finer punctuation separate it from E. mexicana, Jac. Numerous

examples were obtained by Mr. Smith in Western Mexico.

DIPHAULACA (p. 263).

Diphaulaca intermedia (p. 264).

To the locality given add:—Mexico, Amula, Chilpancingo, R. Papagaio, all in

Guerrero (H. H. Smith).

The Mexican specimens differ somewhat from the type, and also vary amongst

themselves, but they agree in the closely punctate-striate elytra and in the black tarsi ;

in some examples, however, the antenne and the greater part of the legs are entirely

black.

Hab. Mzxico, Atoyac in Vera Cruz (H. H. Smith).—Cotomsta }.

The single specimen obtained by Mr. Smith agrees perfectly with the author’s

description; it is a species of very bright metallic blue colour, and is principally

distinguished by the deep fovea between the eyes, and the fulvous colour of the base of

the four anterior femora.

LACTICA (p. 270).

6 (a). Lactica inornata.

Testaceous, the antenne obscure fuscous ; thorax transverse, the basal sulcus deep, the surface impunctate ;

elytra microscopically punctured.

Length 12 line.

Head with one or two punctures near the eyes, the latter widely separated and broadly emarginate, the frontal

elevations absent, the clypeus broadly triangular; antenne three-fourths the length of the body, slender,

entirely pale fuscous, the fourth joint one half longer than the third ; thorax more than twice as broad

as long, the sides very slightly rounded, and with a narrow reflexed margin, the anterior angles obliquely

truncate, the surface entirely impunctate, the basal sulcus deep, slightly sinuate in the middle, and

parallel, the shoulders prominent, the surface only visibly punctured when seen under a very strong lens ;

underside and legs entirely testaceous.

Hab. Panama, Volcan de Chiriqui (Champion).

Larger and of a more obscure testaceous colour than L. uniformis ; the eyes more

widely separated ; the antenne unicolorous; the thorax much more transverse and its

sides more rounded. ;

Lactica scutellaris (p. 273).

To the Mexican localities given, add :—Colima city, Tapachula in Chiapas (Hoge),

Atoyac in Vera Cruz, Teapa in Tabasco (H. H. Smith).

Dr. Horn in his “Synopsis of the Halticini of Boreal America” (Trans. Am. Ent.

Soc. xvi. p. 231) remarks that LZ. scutellaris would be better placed in the genus

Haltica, and that it is congeneric (and probably also specifically identical) with #. rufa,

Ilig. I cannot agree with this opinion; moreover, the present species was not

described by myself in this work, as stated by Dr. Horn, but by Olivier, and at greater

length by von Harold. The last-mentioned author also places the species in Lactica,

although the thoracic depression is not so well marked as usual ; but this is frequently

the case in other members of the genus. In the broad (not acutely raised) clypeus

L. scutellaris agrees entirely with the present genus. As regards H. rufa, Dr. Horn

describes the third joint of the antenne as distinctly longer than the fourth, and the

entire antenne as piceous; in L. scwtellaris the third and fourth joints are equal or

nearly so, and the basal two joints are rufous. With scarcely an exception, all the

species of the genus Haltica have metallic blue or green elytra and a narrow thoracic

Lactica cupreata (p. 281).

To the locality Mexico, add :—Yolotepec, La Parada (Sallé).

The two additional specimens contained in the Sallé collection are more than double

the size of the type, and they belong doubtless to the female sex; in one of them the

260 PHYTOPHAGA.—SUPPLEMENT.

36. Lactica crassicornis.

Pale fulvous or testaceous, the antenne (the basal three joints excepted) black; thorax impunctate, the basilar

groove deep; elytra very finely punctured.

3. Basal joints of the antenne robust, the others with a fringe of long hairs.

@. Elytra with two longitudinal coste at the sides, the antenne normal.

Length 13 line.

3. Head with a few deep punctures near the eyes, the middle portion triangularly raised, the clypeus

acutely raised, but not broad, the apex of the mandibles black; antenne extending to a little beyond the

middle of the elytra, black, the basal three joints fulvous, the first joint long, strongly thickened, the

second short, the third and fourth equal, the others more slender and elongate, with a fringe of black

hairs on their inner margin; thorax twice as broad as long, the sides very little rounded, the anterior

angles somewhat oblique, the surface impunctate, with a transverse deep basal sulcus, which is sinuate

at the middle and interrupted by a deep longitudinal groove at the sides; elytra with an obscure depres-

sion below the base, the punctures only visible under a very strong lens; Jegs rather robust.

Hab. Mexico, Acapulco in Guerrero, Tapachula in Chiapas (/ége).

This Lactica will not be difficult to recognize in either sex, the antenne being robust

and hairy in the male, and the elytra having two cost in the female; these coste are

very strongly raised, and they arise from a common stem at the shoulder, and are

joined at the apex; the raised middle portion of the head is another peculiarity of

this species.

37. Lactica quadrinotata. (Tab. XLI. fig. 21.)

Ovate, pale testaceous ; the antenne, tibie, and tarsi piceous; head and thorax obscure fulvous, the basal

sulcus of the latter almost obsolete ; elytra extremely finely punctured, testaceous, with four small black

spots placed transversely along the basal margin.

Length 2 lines.

Head entirely impunctate, fulvous, the eyes large, a single deep puncture in front of their inner margin, the

clypeus strongly raised and widened anteriorly ; the antenne extending to about the middle of the elytra,

piceous, the basal two joints fulvous, shining, the third joint much shorter than the fourth; thorax more

than twice as broad as long, the sides straight, the anterior angles oblique, the surface entirely impunc-

tate, the basal sulcus almost obsolete, the lateral impression at each end of it a little more distinct ; elytra

ovate, pale testaceous, very minutely punctured, each with two small round blackish spots close to the

basal margin; underside and legs testaceous, the upper edge of the femora at the apex and the tibie and

tarsi more or less piceous; the first joint of the posterior tarsi rather longer than the following two joints

together.

Hab. GuatemaLa, Chiacam in Vera Paz (Champion).

One specimen.

38. Lactica hypocrita.

Lactica hypocrita, Harold, Col. Hefte, xiv. p. 22’.

Hab. Panama, Bugaba in Chiriqui (Champion).—Co.ompta |.

The single example obtained at Bugaba agrees in every respect with the author’s

description. L. hypocrita may be known from the other species of Lactica from our

region by the elytra having the anterior portion fulvous and the posterior portion

black ; it is only one line and a half in length.

39. Lactica elegans ?

Lactica elegans, Harold, Col. Hefte, xiv. p. 151.

A specimen from Chiriqui merely differs from von Harold’s description in having

the elytra black (the sutural and lateral margins excepted) instead of blue.

Hermeophaga, Foudras, in Mulsant’s Col. Fr. p. 299 (1860); Weise, Naturg. Ins. Deutschl. vi.

p- 849 (1885). .

The species belonging to this genus are few in number, and principally inhabit the

Old World. In their general appearance and structure they resemble Lactica and

Diphaulaca; the thorax has its posterior margin produced in the middle, and the

sulcus is generally sinuate; the four anterior tibie are armed with a small spine..

Haltica minuta and H. parvula, Jac., would, no doubt, be better placed in Hermeo-

phaga.

1. Hermeophaga parvula.

Haltica parvula, huj. op. p. 299.

To the localities given, add :—Mzexico, Tuxtla (Sallé), Teapa in Tabasco (H. H.

Smith); Guatemaua, Yzabal (Sallé).

2. Hermzophaga minuta.

Haltica minuta, huj. op. p. 299.

3. Hermzophaga fulva.

Fulvous, the legs black, the thorax impunctate, the elytra extremely minutely punctured.

Length 1 line.

Hab. GuateMaua, Tamahu in Vera Paz (Champion).

This small species agrees entirely in its structural characters with Herm@ophaga, but

differs from all the other members of the genus, H. semistriata excepted, by its fulvous

colour. The antenne are long and slender, and have their third joint twice as long as

the second. The thorax has the anterior angles oblique, and the posterior margin

produced in the middle ; the basal sulcus is deep, slightly sinuate, and interrupted by

a short longitudinal groove at the sides, beyond which it extends to the posterior

angles. The elytra are cylindrical in shape, scarcely perceptibly depressed below the

base, with extremely fine punctures placed in rows, which disappear almost entirely

near the apex. ‘The legs are black.

A single specimen.

262 PHYTOPHAGA.—SUPPLEMENT.

4, Hermeophaga cyaneipennis.

Black, the four or five basal joints of the antenne, the head, thorax, and legs fulvous; thorax distinctly

punctured ; elytra dark blue, strongly punctured in semi-regular rows. .

Length 13 line. _

Of rather broad, subcylindrical shape; the head impunctate, the frontal elevations trigonate, distinct, the

clypeus somewhat swollen ; antenne rather long, black, the lower four or five joints fulvous, the second

and third joints equal, the fourth slightly longer; thorax transversely convex, the sides very nearly

straight, the anterior angles oblique, the posterior margin moderately rounded, the median lobe broad,

but not much produced, the basal sulcus deep, slightly sinuate, and extending to the posterior angles

(but not interrupted by a longitudinal groove towards the sides), the surface finely but distinctly, and

not very closely punctured; scutellum black ; elytra convex, cylindrical, not depressed below the base,

the punctures strong and placed in closely approached and rather regular rows, which become less

distinct towards the apex; breast and abdomen black; legs fulvous, the posterior femora slightly

darker.

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

Easily known from H. parvula by the distinctly punctured thorax and the strongly

punctured elytra.

5. Hermzophaga smithi.

Black, above metallic green; thorax impunctate, the sulcus deep, sinuate, and interrupted laterally by a

longitudinal groove ; elytra convex, punctured in closely approached rows.

Length 1 line.

Of rather robust, subcylindrical shape, and bright metallic green colour; the head entirely impunctate, the

frontal elevations in the form of narrow oblique ridges, the carina acute, the eyes very large; antenne

slender, filiform, black, joints 3 and 4 but slightly longer than 2; thorax transversely convex, the sides

straight, the anterior angles oblique, the posterior margin arcuately produced at the middle, the basal

sulcus deep, sinuate, and interrupted towards the sides by a longitudinal groove, beyond which it is

continued to the lateral margin, the anterior portion also with an obsolete depression (only visible in

certain positions), the surface entirely impunctate; elytra cylindrical, slightly broader at the base than

the thorax, without basal depression, rather strongly punctured in closely approached rows, which become

less distinct towards the apex ; underside black, the breast with a metallic greenish gloss; legs black or

piceous, the cox, the apices of the tibie, and the tarsi more or less dark fulvous.

Hab. Mexico, Teapa in Tabasco (H. H. Smith); Guaremaua, Lanquin in Vera Paz

(Champion).

Broader and much more robust than H. minuta, and of a bright metallic green

colour.

6. Hermeophaga eneipennis.

Black, above greenish-zneous; the basal three joints of the antenne pale fulvous; thorax impunctate; elytra

obscurely depressed below the base, rather strongly and regularly punctate-striate.

Length 2 line.

Hab. GuatemMaua, Chiacam in Vera Paz (Champion).

Smaller, narrower, and of less robust shape than H. smithi; the colour of the upper

surface darker, zeneous (instead of metallic green); the antenne with the basal joints

pale fulvous; the thorax impunctate, slightly widened at the sides before the middle, the

basal sulcus deep and sinuate ; the elytra slightly depressed below the base, rather strongly

and regularly punctured in not very closely placed rows; the tibie and tarsi more or

less piceous. The allied H. teapensis differs in having the five or six basal joints of

the antenne and the anterior and intermediate legs flavous.

7. Hermezophaga semistriata.

Entirely fulvous; the thorax with a few fine punctures; elytra obscurely depressed below the base, finely

punctate-striate, the interstices finely punctured.

Length 1 line.

Head impunctate, the frontal elevations oblique ; the antenne scarcely extending to the middle of the elytra,

the lower seven joints shining, the others more opaque, pubescent, and slightly infuscate, the third and

fourth joints equal; thorax one half broader than long, the anterior angles oblique, the sides straight,

the posterior margin produced in the middle, the basal suleus moderately deep and extending to the

posterior angles, the surface with a few very minute punctures; elytra with a shallow depression below

the base, finely and regularly punctate-striate, the interstices finely punctured; underside and legs

fulvous.

Hab. Panama, Volcan de Chiriqui (Champion).

H. semistriata may be easily recognized by the punctate-striate elytra and the

entirely fulvous colour; the strie of the elytra are widely separated.

8. Hermzophaga teapensis.

- Black, above obscure greenish-ceneous; the basal joints of the antenne and the legs (the posterior femora

excepted) flavous ; the thorax impunctate, the elytra distinctly and rather regularly punctate-striate.

Length #-1 line.

Head impunctate, the frontal tubercles in the form of narrow oblique ridges; eyes large, not narrower than

the interocular space ; antenne very long and slender, the lower five or six joints flavous, the others

fuscous, the second, third, and fourth joints equal; thorax transversely convex, the sides straight, slightly

converging anteriorly, the anterior angles oblique, the posterior margin arcuately produced in the middle,

the transverse sulcus deep and extending completely’ across, the surface impunctate; scutellum small ;

elytra cylindrical, slightly widened towards the middle, the disc with close rows of fine punctures which

become entirely obliterated below the middle; underside black; legs flavous, the posterior femora

piceous.

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

9. Hermxophaga fulvitarsis.

Ovate, convex, black, above metallic dark blue, the basal three joints of the antenne and the tarsi fulvous ;

thorax finely, the elytra more distinctly, punctured.

Length 13 line. .

Head impunctate; the frontal elevations strongly raised, transverse, each divided at the middle by a broad

and deep depression ; the carina acutely raised ; antenne slender, filiform, black, the lower three joints

fulvous, the first joint long and slender, the third, fourth, and fifth joints each twice as long as the second,

the others shorter; thorax transversely convex, the disc swollen, the sides straight, the anterior angles

oblique, thickened, the posterior margin arcuately produced in the middle, the basal sulcus deep, sinuate,

and bounded at the sides by a deep longitudinal groove, the surface very finely punctured, bluish-black ;

elytra widened towards the middle, not depressed below the base, convex, more strongly punctured than

the thorax, the punctures somewhat regularly arranged in rows; underside and legs black, the extreme

apex of the tibiee and the tarsi fulvous.

Hab, Guatemata, San Gerénimo (Champion).

264 PHYTOPHAGA.—SUPPLEMENT.

In the shape of the thorax &c., this insect agrees with Hermeophaga, but it appa-

rently has no spine on the anterior tibie. The form of the frontal tubercles and the

colour of the tarsi are its most conspicuous characters.

PLECTROTETRA (p. 284).

Plectrotetra proxima (p. 286).

The locality for this species is Zapote, Guatemala, and not Bugaba, Panama, as

stated on p. 286.

Plectrotetra guatemalensis (p. 288).

To the locality given, add :—Mexico, Cuernavaca in Morelos (H. H. Smith).

16. Plectrotetra multipunctata.

Obscure piceous, pubescent, the head, thorax, and legs fulvous; thorax remotely punctured; elytra metallic

greenish, strongly punctate-striate, the interstices closely and finely punctured.

Var. Entirely pale testaceous.

Length 14 line.

Head with a few punctures, the vertex obscure piceous, the lower portion fulvous; the antenne extending

very little beyond the base of the elytra, black, the basal joint fulvous, the third and fourth joints equal,

the terminal joints slightly thickened ; thorax transverse, the sides rounded, slightly narrowed in front,

the basal sulcus deep and sinuate, the surface remotely punctured and sparingly pubescent; elytra

greenish, strongly punctate-striate, the interstices finely punctured throughout and clothed with greyish

pubescence ; beneath piceous; the breast in front and the legs fulvous, pubescent; the posterior tibise with

a distinct spine ; the claws obsoletely bifid.

Hab. Mexico, Yolos, Yolotepec (Salié).

This small species differs from its allies (P. hirsuta excepted) by the pubescence of

the upper surface, and from all others of the genus by the closely punctured elytral

interstices.

17. Plectrotetra nigripennis, (Tab. XLI. fig. 22.)

Broad and robust, fulvous, the antenne, tibie, and tarsi black; thorax without basal groove, strongly

transverse, sparingly punctured ; elytra black, opaque, closely punctured, the interstices finely aciculate.

Length 33 lines.

3. Of broad, subdepressed shape ; the head impunctate, the eyes oblique, entire, the frontal elevations broad,

not much raised, bounded behind by a transverse groove, the labrum flavous ; palpi slender; the antenne

extending to about the middle of the elytra, black, the basal joint fulvous below, the third joint slightly

longer than the fourth, the apical joints shorter, slightly tapering; thorax very strongly transverse, the

sides rounded towards the base, the anterior angles dentiform, produced outwards, the posterior angles

obsolete, the dise with a short longitudinal groove on each side at the base (the usual transverse sulcus

quite obsolete), a round fovea near the anterior angles, and an obsolete median channel,

sparingly and finely punctured at the sides and at the middle, reddish-fulvous ; scutellum broad, sub-

triangular, fulvous; elytra black, opaque, with a feeble basal depression near the suture, the entire disc

closely and rather strongly punctured, the punctures near the suture arranged somewhat in rows, the

interstices finely aciculate ; underside and the femora and tibix fulvous, clothed with whitish pubescence ;

the tibize dilated at the apex, canaliculate, the intermediate and posterior pairs mucronate; the tarsi black,

the first joint dilated, the claws bifid.

Hab. Mexico, Santiago Iscuintla (Flohr).

This species, the largest yet known of the genus, possesses the most important of the

characters of Plectrotetra, viz. the transverse thorax and the bifid claws, but it wants

the thoracic sulcus; the longitudinal groove on each side of the thorax, however,

indicates the usual limit or interruption of the sulcus. The antenne are formed as in

the typical species of Plectrotetra. A single specimen of this insect has been kindly

added to my collection by Mr. Flohr.

HEMIPHRYNUS. (To follow the genus Phrynocepha, p. 294.)

Hemiphrynus, Horn, Trans. Am. Ent. Soc. xvi. p. 212 (1889).

The generic name Hemiphrynus has been proposed by Dr. Horn to include Phryno-

cepha intermedia, Jac., this insect differing from Phrynocepha in the scarcely sulcate

tibie. Two other species are now added to it. Dr. Horn remarks (op. cit.) that

P. elongata, Jac., also probably belongs to Hemiphrynus; P. elongata, however, has

distinctly sulcate tibie.

2. Hemiphrynus tenuicornis. (Tab. XLI. fig. 23, 3.)

Fulvous, the antenne (the basal four joints excepted), breast, and abdomen black; thorax impunctate ;

elytra dark violaceous, closely punctured, the interstices obsoletely longitudinally depressed.

¢. Antenne as long as the body, the basal joints robust.

¢@. Antenna entirely filiform.

Length 13-2 lines.

3. Head impunctate, the frontal elevations but little raised, elongate ; antenne as long as the body, black,

the basal four joints fulvous, rather robust, the terminal joints gradually becoming thinner, the third

joint very elongate, distinctly longer than the fourth; thorax about one half broader than long, narrowed

in front, the sides rounded, the angles not prominent, the surface impunctate, with a shallow transverse

basal sulcus on either side of the middle; scutellum black; elytra widened posteriorly, dark metallic

violaceous, very finely and closely punctured, and with shallow longitudinal grooves ; legs robust, fulvous,

- the tibie not channelled.

Hab. Mexico, Yolotepec (Sallé).

H. tenuicornis may be at once distinguished from H. intermedius by the colour and

sculpture of the elytra in connection with the long antenne in both sexes; the elytral

grooves are a little more strongly marked in the female than in the male.

3. Hemiphrynus sulcatipennis. (Tab. XLI. fig. 24.)

Black, the head, the basal joints of the antenne, the thorax, and legs fulvous; thorax with the basal sulcus

very feeble ; elytra dark violaceous, closely punctured, the sides with a deep longitudinal groove.

Length 14—13? line.

Head somewhat rugosely punctured near the eyes, with a more or less distinct central ridge, the frontal

elevations small but distinct, the carina short and feeble; palpi fulvous, the apical joint fuscous, acute ;

antennz nearly two-thirds the length of the body, black, the basal four joints fulvous, the fourth joint

distinctly longer than the third; thorax transverse, the sides rather strongly rounded, the angles not

prominent, the surface very minutely and sparingly punctured, the basal sulcus only indicated towards

the sides, shallow, not extending across the entire disc; scutellum black; elytra very closely and finely

punctured, dark violaceous, shining, the sides with a deep longitudinal depression commencing below the

shoulders and terminating at some distance from the apex; the breast and abdomen violaceous-black, the

legs fulvous.

Hab. Mexico, La Parada (Sallé), Omilteme in Guerrero (H. H. Smith).

In the shape of the thorax and its obsolete transverse basal depression, in the un-

grooved tibie, and in the system of coloration, this species agrees with Hemiphrynus.

The elytra have a deep lateral depression in both sexes.

HALTICA (p. 294).

Haltica guatemalensis (p. 297).

To the locality given, add:—Mexico, Northern Sonora (Morrison).

The specimens from Sonora merely differ from the Guatemalan ones in being entirely

blue in colour and in having the elytral coste obsolete.

Hab. Norta America, Texas!?, New Mexico?, Arizona 2,—Mexico, Guanajuato,

Orizaba (Sal/é).

A North-American specimen kindly given to me by Dr. Horn agrees very nearly

with those from Mexico; but in the latter there are scarcely any punctures near the

eyes, and the fourth joint of the antenne is slightly longer than the third, these joints

being equal in length in the type.

Sonoran specimens agree perfectly with an example kindly given to me by Dr. Horn.

21. Haltica abdominalis,

Reddish-fulvous, the terminal joints of the antenne, the posterior femora partly, the tibie and tarsi more or

less, and the abdomen black ; thorax with the basal sulcus entire; elytra metallic blue, more or less

regularly punctate-striate, the sides longitudinally depressed.

_ Length 14-2 lines,

Head impunctate, reddish on the vertex, flavous on the lower portion, the frontal elevations strongly raised,

rather elongate ; antenn slender, the third and fourth joints equal, the lower three joints pale fulvous,

the others black ; thorax narrowed at the base, the basal sulcus entire, the surface impunctate, reddish-

fulvous ; scutellum fulvous; elytra with rather regular rows of punctures, which become much deeper

laterally, the sides with a more or less distinct longitudinal depression, the apex nearly impunctate ;

underside and the anterior femora flavous or fulvous, the tibie entirely or at the apex, the tarsi, the

apices of the posterior femora, and the abdomen black.

Hab. Mexico, Atoyac in Vera Cruz, Teapa in Tabasco (H. H. Smith); Guaremata,

La Tinta in Vera Paz (Champion).

H. abdominalis seems to be allied to H. burgessi, Crotch, from Florida; but differs

by its larger size, the colour of the tibie and tarsi, and the punctate-striate elytra, this

last-mentioned character giving it the appearance of a Diphaulaca. The blunt (not

produced) anterior angles of the thorax will prevent its being mistaken for a species of

that genus; there is also no depression whatever at the base of the elytra. The

Guatemalan specimen is much larger than those from Mexico.

22. Haltica satellitia. |

Oblong-ovate, dark metallic blue; the thorax blackish, impunctate, the basal sulcus entire; elytra closely and

finely punctured in rows.

Length 13-1? line.

Head impunctate, the frontal elevations and the carina broad; the antenn» robust, extending to beyond the

middle of the elytra, black ; the thorax one half broader than long, not wider at the base than in front,

the sides feebly rounded, the basal sulcus distinct, straight, and extending almost or entirely across the

disc, the surface smooth except for a few punctures near the anterior angles, almost black; scutellum

black ; elytra punctured in close and rather regular rows, which are distinct to the apex; underside and

legs black with a slight bluish tint. .

Hab. Mexico, Presidio de Mazatlan (Forrer), Jalapa (Hoge); GuatemaLa, Duefias

(Champion).

_ The nearly black and entirely impunctate thorax and the almost regular punctuation

of the elytra (the punctuation varying, however, in depth in different specimens, but

always distinct to the apex) distinguish H. satedlitia from the blue varieties of H. ignita,

to which it is perhaps most nearly allied. The last ventral segment of the male hasa

very slightly prominent median lobe, without depression. 4. satellitia is of a more

ovate shape than the examples I refer to H. cgnita.

23. Haltica simplex.

Obscure seneous or blue, the antenne and legs piceous or black; thorax in great part impunctate, the basal

sulcus entire, the space behind it finely punctured; elytra rather strongly, closely, semi-regularly

punctured.

Length 1? line.

Head impunctate, except for a few deep punctures near the eyes, the frontal elevations broad and not strongly

raised, the carina also comparatively broad and distinct ; antenne extending to about the middle of the

elytra, black, the terminal joints slightly thickened, the basal joints more or less stained with fulvous and

gradually increasing in length ; thorax about one half broader than long, the sides rather strongly rounded

at the middle, the basal sulcus distinct and extending completely across the disc, the latter smooth, a few

fine punctures near the anterior angles, the space behind the sulcus also more or less distinctly punctured ;

elytra with the shoulders rounded, finely and closely punctured, the punctures almost obsolete below the

middle.

Hab. GUATEMALA, Rio Naranjo, Paso Antonio (Champion); PanaMa, Bugaba, David,

Tolé (Champion).

Chiefly distinguished by the dull eneous or bluish colour, the comparatively broad

frontal elevations and carina, and the finely punctured basal part of the thorax.

Allied to H. ignita and H. forreri; the latter, however, has a rather longer thorax, and

more distantly and regularly punctured elytra.

24. Haltica amicula.

Oblong, narrowed posteriorly, metallic green ; thorax minutely punctured, the basal sulcus interrupted at the

sides ; elytra minutely granulate and very finely punctured, narrowed posteriorly.

Length 14 line.

Of a not very bright metallic green colour; the head entirely impunctate, the frontal elevations broad, the

carina much swollen; the antennex scarcely extending to the middle of the elytra, the terminal joints

gradually thickened, the third and fourth joints equal, the basal joints more or less metallic green or

cupreous ; thorax of equal width before and behind, about one half broader than long, the sides evenly

rounded, the surface extremely minutely and closely punctured (the punctuation only visible under a

strong lens), the basal groove narrow and abbreviated on each side; elytra narrowed at the base and

apex, finely granulate, and a little more distinctly punctured than the thorax; underside metallic

greenish, the last ventral segment of the male with a slight depression at the apex.

Hab. Mexico, Ventanas in Durango (Fforrer).

Closely allied to H. foliacea, Lec., but less parallel, the thorax not narrowed in front

and with the basal groove distinct.

HALTICA. 269

Head rugosely punctured between the eyes, the frontal elevations broad, trigonate, the carina also widened,

_ the mandibles fulvous; antenne extending to the middle of the elytra, black, the lower four joints fulvous

at the base, joints 2-4 gradually increasing in length ; thorax nearly quadrate, comparatively long, the

sides scarcely rounded, the basal groove almost entirely obliterated or only very faintly indicated, the

surface rather closely but somewhat irregularly punctured, the interspaces slightly granulate ; scutellum

broader than long, smooth; elytra narrow and parallel, the shoulders scarcely prominent, the surface

punctured like that of the thorax, but with the punctures arranged in close and rather regular rows which

are distinct to the apex; underside finely granulate, without punctures; legs entirely fulvous; the last

ventral segment of the male with a rounded scarcely projecting median lobe.

Hab. Mexico, near the city (H. H. Smith), Guanajuato (Sallé).

The narrowly elongate shape, the quadrate thorax and its close punctuation, and the

fulvous legs will help to distinguish this species. The variety with fulvous antenne

was obtained at Guanajuato.

26. Haltica angulicollis.

Narrowly elongate, black, above dark blue; antenne slender, filiform, the basal two joints obscure fulvous ;

thorax finely granulate, the sulcus almost obsolete on the dise but more distinct at the sides; elytra very

closely and irregularly punctured.

Q. Elytra with an acutely raised lateral ridge which is abbreviated near the apex.

Head somewhat rugose between the eyes, the latter large and prominent; the frontal elevations rather elongate,

not strongly raised ; the margins of the clypeus and labrum testaceous; antenne long and filiform, the

third and the following joints equal in length, the first and second joints more or less fulvous at the apex ;

thorax short, transverse, very little narrowed at the base, the sides feebly rounded, the anterior angles

oblique, thickened, the surface minutely granulate, without punctures, but with some small irregular

depressions, the basal sulcus very shallow, more distinct at the sides than at the middle, the basal margin

slightly sinuate in the centre; scutellum black; elytra with a feeble basal depression, the shoulders

rather prominent, the surface very closely and distinctly punctured throughout, the sides slightly longi-

tudinally depressed in the male, but with an acute ridge, commencing at the shoulder, in the female ;

underside and legs black; last ventral segment in the male simple.

Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith).

The long and filiform antenne, the short and finely granulate thorax, and the oblique

anterior angles of the latter chiefly define this species. The female has an acutely

raised lateral ridge to the elytra.

27. Haltica fulvipes.

Violaceous-black, the legs fulvous; thorax finely and sparingly punctured, the basal sulcus nearly obsolete ;

elytra closely and distinctly semi-regularly punctured, the apex nearly impunctate.

elevations broad and but feebly raised ; antenne black, the basal joints more or less stained with fulvous,

the second, third, and fourth joints gradually increasing in length, the terminal jointe slightly thickened ;

thorax rather convex, about one half broader than long, widened at the sides before the middle, the base

slightly narrowed, the surface finely but distinctly and not closely punctured, the basal sulcus only faintly

visible at the sides ; elytra with rather regular and closely placed rows of strong punctures, which gradually

diminish towards the apex; underside nearly black; legs entirely fulvous.

Hab. Nicaracua, Granada (Sallé); Panama, David in Chiriqui (Champion).

270 PHYTOPHAGA.—SUPPLEMENT.

Evidently allied to H. opulenta, Horn; the latter, however, is described as having

fulvous antenne, a very wide thorax, and finely but not closely punctured elytra. The

Nicaraguan specimens are of a bluish tint, and they have the elytra not quite so

strongly punctured as in the Chiriqui examples. H. elongata, which also has fulvous

legs, differs from H. fulvipes by the nearly quadrate thorax, and by the distinct punc-

tuation at the apex of the elytra.

28. Haltica gracilis.

Oblong, dark violaceous-blue, the antenne black ; thorax impunctate, the basal margin obsoletely depressed in

the middle and at the sides; elytra closely and finely punctured, the sides longitudinally costate in the

female; underside black; the extreme base of the coxe and the knees fulvous.

Length 1-12 line.

Head with the usual deep punctures near the eyes, the frontal elevations strongly raised, the carina acute ;

antenne with the terminal joints scarcely thickened, the third joint slightly longer than the second ;

thorax a little widened at the base, the sides nearly straight, the anterior angles oblique, the surface

impunctate, the usual sulcus only indicated by a depression at the middle of the basal margin and by

another on each side; scutellum large, triangular, black; elytra with a feeble depression below the base,

very finely and closely punctured in rows, the sides with a distinct ridge extending from the shoulder

almost to the apex in the female, simple in the male.

Hab. Panama, Volcan de Chiriqui (Champion).

This small species may be known by the thorax being impunctate and without a

well-defined groove. The laterally costate elytra in the female, and the fulvous colour

of the base of the coxe and knees, will further help to distinguish H. gracilis, which

seems to vary greatly in size.

29. Haltica purulensis.

Black, above metallic blue, the first three joints of the antennw fulvous; thorax impunctate, the sulcus only

indicated at the base by a depression; elytra extremely minutely punctured, the base somewhat swollen.

Length 1 line.

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

Rather smaller than H. gracilis; the antenne much more slender, with the third and

following joints more elongate, and the basal three joints fulvous; the thorax with the

usual transverse groove represented by a faint depression at the middle of the basal

margin; the elytra scarcely perceptibly punctured (even when seen under a strong

lens), and with the basal portion distinctly raised.

30. Haltica longicornis. (Tab. XLI. fig. 25, ¢ .)

Dark violaceous-blue or greenish; the antennew black, as long as or longer than the body in the male, much

shorter in the female ; thorax closely punctured and finely rugose, the basal sulcus very shallow; elytra

extremely closely and distinctly punctured, the interstices in the female rugose.

Length 2-22 lines.

Head finely rugose at the sides, with a single deep puncture near the eyes, the middle portion smoother and

triangularly raised; the frontal elevations broad, feebly raised, and somewhat elongate; the clypeus

swollen anteriorly; the margin of the labrum testaceous; antenne very long and slender, extending to

the end of the elytra in the male, the first joint robust, more or less stained with fulvous, the second joint

short, black (sometimes fulvous), the third and the following three joints very elongate and slender, the

other gradually decreasing in length; thorax nearly twice as broad as long, the sides rounded near the

middle, the anterior angles obliquely thickened, the basal groove very shallow, broad, and abbreviated

on each side, the anterior portion of the disc obsoletely bi-impressed, the surface irregularly and not

closely punctured, the interspaces minutely granulate; elytra very closely and rather strongly punctured

throughout, the sides somewhat depressed longitudinally, the apex broadly rounded ; the underside coloured

as above.

Hab. Guatemana, Ostuncalco, Cerro Zunil, Zapote, Calderas, San Gerénimo (Cham-

pion).

This is a rather abnormal species, having very long and slender antenne in the male,

and a somewhat rugose upper surface, characters not to be found amongst other members

of the genus Haltica. In the single specimen from Ostuncalco, a female, the colour is

greenish, and the thorax and elytra are finely rugose.

31. Haltica cupricollis.

Obscure cupreous or eneous, the antenne black; the thorax cupreous, semiopaque, the basal sulcus nearly

obsolete; elytra dark blue, very finely and rather closely punctured. .

Length 14 line.

Head minutely granulate, metallic greenish, the frontal elevations indistinct, the carina acute at its lower

portion; antenne black, the lower two joints more or less stained with fulvous, the others slightly

and gradually thickened ; thorax one half broader than long, the sides scarcely rounded, a little narrowed

in front, the surface cupreous, more or less shining, extremely finely punctured, the basal groove only

indicated at the sides; scutellum obscure cupreous; elytra dark blue, slightly widened towards the

middle, the punctuation extremely fine and arranged in close rows, which become finer towards the apex ;

underside and legs obscure cupreous, clothed with fine whitish pubescence.

Hab. Mexico, Ventanas in Durango (Porrer), Mexico city (H. H. Smith), Tupataro

(Sallé). |

The colour of the head and thorax and the almost entirely obliterated groove of the

latter separate this species from any other Haltica from our region. In coloration

H. cupricollis resembles H. carinata, Germ., the latter, however, has a very deep

thoracic groove. The specimens obtained near the city of Mexico have the legs

piceous and scarcely metallic, and the thorax shows some depressions at the side.

32. Haltica rugosa.

Elongate, greenish-sneous; the thorax finely rugose, without distinct basal sulcus; elytra closely punctured,

the interstices transversely rugose; underside clothed with greyish pubescence.

Length J] ?—2 lines.

Of rather elongate, posteriorly widened shape; the head scarcely perceptibly punctured and finely rugose ;

antenne blackish, rather robust, the third and following joints nearly equal; thorax about one half

broader than long, the sides and the posterior margin rounded, the former rather broadly margined, the

basal sulcus only indicated by a small median depression, the surface uneven, slightly raised at the sides,

strongly and rather closely punctured, the interspaces finely granulate; scutellum smooth, black; elytra

depressed, punctured like the thorax, with the interstices transversely rugose throughout; underside

of the male deeply bifurcate at the apex.

Hab. Mexico, Pinos Altos in Chihuahua (Buchan-Hepburn), Hacienda de San

Miguelito (Dr. Palmer), Guanajuato (Sallé), Morelia in Michoacan (Hége).

An aberrant species, differing from its allies by the ungrooved thorax in connection

with the rugosely sculptured upper surface. Some examples are of a more bluish

colour and less strongly rugose. The description is taken from Dr. Palmer’s specimens.

33. Haltica sublevipennis.

Fulvous, the terminal joints of the antenne and the breast and abdomen black ; thorax with the basal sulcus

distinct only at the sides; elytra violaceous-blue, entirely impunctate.

Length 2 lines.

Of posteriorly widened shape; head impunctate, the middle of the vertex longitudinally raised, the frontal

elevations very distinct ; antenne slender und filiform, extending nearly to the end of the elytra, the lower

four joints fulvous, the rest black, the second and the following two joints gradually becoming more

elongate ; thorax twice as broad as long, the sides rounded at the middle, with a narrow margin, the base

with a very obsolete depression at the sides and another at the middle, the surface entirely impunctate,

fulvous; scutellum large, black; elytra dark violaceous, extremely finely and not closely punctured, the

punctures only visible under a strong lens; breast and abdomen black, the legs fulvous.

Hab. Muxico, Coscomatepec (Sallé).

This species deviates considerably from the typical members of the genus, not only

in coloration, but in having very long antenne and an impunctate, scarcely sulcate

thorax. The specimens received are apparently all females. Labelled Diphaulaca

SYPHREA (p. 301).

Syphrea pretiosa (p. 302).

To the localities given, add:—Mexico, Ventanas in Durango (Hége), Chilpancingo

The Mexican specimens differ from the type in having entirely fulvous legs.

2. Syphrea angustata.

Elongate, subcylindrical, piceous or blackish, the head, the basal joints of the antenne, and the thorax fulvous ;

elytra nearly parallel, metallic blue, very finely and closely punctured.

Length 2-23 lines.

Hab. Mexico, Monclova in Coahuila (Dr. Palmer), Acapulco, Matamoros Izucar,

Jalapa (Hoge).

S. angustata differs considerably in shape from S. pretiosa, but possesses all its struc-

tural characters and also a similar system of coloration; the antenne, however, are

more robust and have either the first or the basal three joints fulvous; the thorax is

much less transverse, more elongate, and entirely impunctate; and the elytra are not

widened posteriorly but subcylindrical and parallel, and devoid of any basal depression,

their punctuation being either very close and fine or nearly obsolete. The underside

and legs are usually bluish-black or piceous, but in one specimen the legs are obscure

fulvous.

fourth ; thorax piceous, with a slight sneous gloss, subquadrate, one half broader than long, the sides

straight, slightly narrowed towards the base, the anterior angles tuberculiform, the posterior margin with

a produced rounded lobe, the basal sulcus deep, slightly sinuate, punctured, the rest of the surface entirely

impunctate; scutellum small, transverse; elytra broader at the base than the thorax, convex, subcylin-

drical, transversely depressed below the base, fulvous, with a slight metallic greenish gloss, strongly

punctate-striate, the punctures diminishing in size towards the apex and not closely placed; underside

and legs dark fulvous.

Two specimens obtained at Tapachula agree perfectly with the type; the others have

_ the thorax fulvous (instead of testaceous) and devoid of any darker markings, and the

dark stripes of the elytra broader and connected with each other (instead of partially

interrupted, as in the type).

The Guatemalan specimens are generally of small size, and have the sutural margin

very narrowly, the lateral margin more broadly, flavous.

Length 23-3 lines.

Hab. Guaremata, Zapote, Duefias (Champion) ; Costa Rica (Van Patten). +

Extremely close to C. varians, and possibly a variety of that species, from which

it only differs in having the antennae, elytra, underside, and legs entirely black.

DISONYCHA (p. 304).

Disonycha collata (p. 305).

To the localities given, add :—Panama, Bugaba (Champion).

Some of the Mexican localities quoted by me belong to D. politula, Horn, and will

be found mentioned under that species.

5 (a). Disonycha maculipes.

Flavous, the terminal joints of the antenne, a spot at the apex of the femora, and the tibiz and tarsi black ;

thorax impunctate; elytra dark metallic blue, closely and distinctly punctured.

Length 3 lines.

Head with some deep punctures near the eyes, flavous, the frontal elevations indistinct, the labrum and palpi

piceous; antenne not extending to the middle of the elytra, black, the lower three joints flavous, the

fourth joint slightly longer than the third ; thorax transverse, the sides nearly straight, the anterior and

posterior angles oblique, the surface impunctate, flavous; elytra dark violaceous or greenish-blue, very

closely and rather finely punctured ; underside flavous ; legs fulvous, the apices of the anterior femora, a

spot at the extreme apex of the posterior femora, and the tibie and tarsi, black.

Hab. Mexico, San Miguel del Rio (Sallé), Cordova (Hége).

The flavous head and thorax, the distinctly and closely punctured elytra, and the

spot at the apex of the posterior femora distinguish D. maculipes from any of its

similarly-coloured congeners; its size is also proportionately large.

DISONYCHA. ; 27

5 (Bs). Disonycha affinis.

Flavous, the base of the head, the antennsw, the tibie (partly), and the tarsi piceous; thorax and elytra

impunctate, the latter metallic green.

Length 23 lines.

Hab. Guaremata, Duefias (Champion).

Chiefly distinguished from its similarly coloured allies by the more transversely-shaped

thorax ; from D. melanocephala by the flavous colour of the anterior portion of the

head and the colour of the tibiz (which are piceous, except at the base); from

D. mellicollis (Say) by the entirely yellow metasternum and abdomen, and the shining

impunctate thorax.

Very closely allied to D. collata (Fabr.), and perhaps a local variety of that species,

from which it only seems to differ by the bicoloured posterior femora and the more

distinct elytral punctuation.

11 (4). Disonycha angulata. (Tab. XLII. fig. 2.) _

Fulvous, the terminal joints of the antenne and the legs black; head and thorax distinctly punctured, the

latter spotted with piceous; elytra closely punctured, flavous, the sutural and lateral margins, a spot at

the shoulder, an angulated fascia before the middle, another near the apex, and the apex itself, black.

Var. The legs more or less fulvous.

Length 3-33 lines.

Hab. Mexico, Playa Vicente (Sallé), Teapa in Tabasco (Hége) ; GUATEMALA, Teleman

in Vera Paz (Champion).

This species closely resembles D. trifasciata in its system of coloration; but differs

from it by the distinctly punctured head and thorax, and by the anterior fascia of the

elytra being angulate at the middle.

26 (a). Disonycha horni.

Disonycha crenicollis, huj. op. p. 316 (part.) (nec Say, Horn).

Pale fulvous and pubescent below, above flavous; the antennae, the upper margin of the femora, the tibie

276 PHYTOPHAGA.—SUPPLEMENT.

After carefully studying Dr. Horn’s description of D. crenicollis (Say) (Trans. Am.

Ent. Soc. xvi. p. 204), I must conclude that the specimens formerly referred by me to

that species, and many others since obtained at Teapa and elsewhere in Mexico, repre-

sent yet another closely-allied form. They differ from D. crenicollis, as defined by

Dr. Horn, in having the black discoidal stripe of the elytra always narrower than the

preceding yellow space, and in the abdomen not being densely punctured, the latter

thickly clothed with silvery pubescence. It may be remarked here that Say’s descrip-

tion was based upon Mexican specimens, and Dr. Horn’s upon examples from the

United States. In D. horni the thorax usually has two small black spots on the middle

of the disc; but these spots are not present in the specimens from Orizaba. D. caro-

liniana (Fabr.) is another allied species ; but it is described by Dr. Horn as having a

pale labrum, a closely punctured abdomen, and yellow legs, the latter with the tips

of the tibiz only piceous.

margined with black, almost imperceptibly punctured.

Length 3 lines,

Of proportionately convex shape; the head rugosely punctured, black, with some obscure flavous spots, the

punctures on the vertex interrupted by a narrow smooth central space ; antenne short and robust, black ;

thorax transversely convex, the sides strongly rounded, the posterior angles oblique, the disc finely and

rather closely punctured ; scutellum broad, black ; elytra pale flavous, very minutely punctured, the basal,

sutural, and lateral margins narrowly black ; underside and legs black, the sides of the breast and of the

abdomen pale fulvous.

Hab. Mexico, Ciudad in Durango (Forrer).

A single example. Quite distinct from any of its congeners by the rugosely punc-

tured head, the colour of the elytra, and the convex shape.

ORODES. (To follow the genus Disonycha, p. 318.)

Body elongate; palpi slender; antenne very long, slender, filiform ; thorax transverse, with a very shallow

transverse groove near the base; elytra punctured in rows; tibiee simple, the posterior pair mucronate ;

the first joint of the posterior tarsi as long as the following three joints together; claws appendiculate ;

prosternum narrowly elongate, flattened ; anterior coxal cavities open.

The single species for which this new generic name is proposed seems to be a

transitionary form between Disonycha, Systena, and Calliphron, differing from each of

them by the long and filiform antenna. The shape of the thorax and the punctate-_

striate elytra will also separate it from Disonycha, and the open coxal cavities from

Systena. ‘The thoracic groove is in some specimens quite obsolete.

1. Orodes nigropictus. (Tab. XLII. fig. 3.)

Testaceous, the antenns (the basal joints excepted) and the vertex black ; thorax impunctate ; elytra with the

basal portion raised, strongly and closely punctured in rows, testaceous, a common transverse patch at the

base extending downwards along the suture, and a longitudinal band at the sides, widened behind and not

_ reaching the apex, black.

Var. a. Elytra black, the lateral and apical margins testaceous.

Var. b. Elytra black, the apical margin testaceous.

Var. c. Elytra entirely testaceous.

Length 2 lines.

Head rather broad, not constricted behind the eyes, the latter moderately prominent; the frontal tubercles

small, indistinct ; the clypeus broad, flattened and strongly deflexed: the vertex remotely but distinctly

punctured, its base sometimes black; antenns extending to two-thirds the length of the elytra, black, the

lower three joints, and sometimes the apical two also, testaceous, all the joints with the exception of the

second elongate and slender, the terminal ones a little shorter; thorax scarcely twice as broad as long, the

sides nearly straight, the angles not prominent, the surface impunctate, testaceous, with a slight transverse

depression parallel to the basal margin, the latter rather sinuate at the middle; scutellum testaceous, its

apex rounded ; elytra with the basal portion distinctly swollen, strongly punctured in closely approached

but not very regular rows, which become almost obliterated near the apex, testaceous, with a more or less

extended common transverse black patch at the base, extending downwards along the suture, and a longi-

tudinal black band at the sides, commencing at the shoulders and gradually widened, but not reaching the

apex; underside and legs testaceous.

Hab. Panama, Volcan de Chiriqui (Champion).

The last abdominal segment in the male has a broadly rounded median lobe, this

being absent in the female. Many specimens. A typical example is figured.

NEPHRICA. (To precede the genus Ceporis, p. 318.)

Nephrica, Harold, Berl. ent. Zeitschr. 1877, p. 182.

A few species from Tropical America constitute this genus. It may be principally

known by the deeply emarginate reniform eyes, the medially dilated or thickened

antennee, and the shape of the thorax. A single species is now known from the State

of Panama.

1. Nephrica inornata. (Tab. XLII. fig. 4.)

Ovate, moderately convex, pale fulvous; the antenne (the first joint excepted), the anterior and intermediate

tibie, and the tarsi black ; thorax nearly impunctate ; elytra rather strongly and closely punctured.

Length 33 lines.

Head impunctate,

margin, the clypeus thickened an

the surface somewhat uneven, the eyes very deeply and broadly emarginate at their inner

d rather broad; the penultimate joint of the maxillary palpi incrassate ;

antenne short and robust, the first joint flavous, the others black, the fourth joint the longest, this and

the following two joints thickened, the five terminal ones much shorter and thinner; thorax nearly three

times as broad as long, the sides rounded at the middle, narrowed in front, the anterior angles obliquely

produced, the base with a short oblique depression on either side near the posterior angles, the surface with

a few minute punctures; scutellum broad, impunctate ; elytra rather convex, strongly and closely punc-

incrassate ; posterior tibie deeply channelled, with a spur at the tip, flavous at the base, black at the

apex; the tarsi and the four anterior tibiw black; claws appendiculate ; anterior coxal cavities open.

Hab. Panama, Bugaba (Champion).

One specimen.

ACANTHONYCHA. (To precede the genus Pelonia, p. 318.)

Body elongate, metallic above; antenna filiform; eyes large; palpi with the penultimate joint thickened ;

thorax subquadrate, subangulate at the sides, obsoletely transversely sulcate near the basal margin; elytra

closely and irregularly punctured, their epipleuree broad, continued to the apex; posterior femora but

slightly incrassate ; posterior tibia mucronate; the first joint of the posterior tarsi as long as the following

three joints united; claws appendiculate ; prosternum narrow; anterior coxal cavities open.

This new genus is proposed for Pelonia elegantula, Baly. It may be known from

Pelonia by the very differently-shaped thorax, the metallic elytra, and other particulars

mentioned above. From Cacoscelis, to which it is closely allied, it differs in the shape

of the thorax, and in the very shallow and more flattened basal groove of the latter.

Pelonia elegantula has the hind femora but little thickened, and the legs slender, these

characters giving it the appearance of a Galerucid; but the broad elytral epipleuree and

the distinct prosternum show that it belongs to the Halticine.

In addition to the varieties already noticed by me, another one, entirely reddish-

fulvous in colour, has been obtained in numbers by Mr. Champion in the Polochic

CALLIPHRON. (To follow the genus Megasus, p. 321.)

Body elongate ; antenne long and robust in the male, shorter and more slender in the female ; thorax transverse,

without basal depression, the sides rounded, the angles obsolete; scutellum large ; elytra punctate-striate ;

posterior femora moderately thickened ; posterior tibie not channelled, mucronate ; anterior tibie unarmed ;

the first joint of the posterior tarsi as long as the following two joints together; claws appendiculate ;

prosternum narrow, convex ; anterior coxal cavities open.

Calliphron. agrees in general appearance with Plectrotetra, but differs from it by the

want of a thoracic groove and by the appendiculate claws.

1. Calliphron ferrugineum. (Tab. XLII. fig. 5, 3.)

Dark fulvous, the antenne and legs piceous or black; head and thorax nearly impunctate; elytra distinctly

punctate-striate, the punctures indistinct near the apex, the interstices flat.

3. Head impunctate, the frontal elevations strongly raised, transverse, bounded behind by a deep transverse

groove, the carina short; palpi rather robust, the terminal joint acute; antenne nearly black, thickly

pubescent, two-thirds the length of the body, the third and following joints nearly equal; thorax trans-

versely convex, about twice as broad as long, the sides rounded, all the angles obsolete, the disc with a

few punctures only near the base; scutellum broad, its apex rounded ; elytra parallel, without any basal

depression, each with nine not very regular but distinct rows of punctures; underside fulvous ; legs

black.

Hab. Panama, Volcan de Chiriqui (Champion).

In the female the antenne are much shorter, the terminal joints particularly so ;

in the male joints 3-5 are more elongate than the others, and the third and fourth are

thickened at their apex. Many specimens.

IPHITROIDES. (To follow the genus Prasona, p. 322.)

Elongate, parallel; antenns filiform, slender; thorax subquadrate, narrowed at the base, the disc with a

transverse sulcus, terminated at the sides by a longitudinal groove; elytra glabrous, finely punctured,

their epipleure broad at the base and continued to the apex ; legs slender, the posterior femora but feebly

dilated ; posterior tibie with a small spine, not channelled ; the first joint of the posterior tarsi as long

as the following three joints together; claws appendiculate; prosternum narrow ; anterior coxal cavities

closed.

This genus is proposed to include some elongate species which somewhat resemble

Iphitrea, Baly, in the form of the thorax; but differ from it by the non-pubescent

upper surface and the appendiculate claws. The posterior femora are only feebly

dilated; but the general facies, the sulcate thorax, the broad elytral epipleure, and the

distinct prosternum are characteristic of the group Halticine.

1. Iphitroides quadrimaculata. (Tab. XLII. fig. 6.)

Pale fulvous ; the antennz nearly as long as the body ; head and thorax impunctate ; elytra very finely and

closely punctured, a rounded spot at the shoulders, and a more elongate one near the apex, piceous.

elongate; palpi rather robust, the terminal joint very short, acute; antenne extending to rather more

than two-thirds the length of the elytra, fulvous, the first joint elongate and thickened, the second less

than half the length of the first, the fourth joint longer than the third; thorax not broader than long,

narrowed at the base, the angles not produced but distinct, the base with a distinct transverse sulcus

bounded at the sides by a longitudinal groove, the surface impunctate, fulvous; scutellum rather long, its

apex broadly rounded ; elytra much wider at the base than the thorax, parallel, the surface rather flat-

tened, extremely closely and finely punctured, with traces of feebly raised longitudinal lines, fulvous or

flavous, each elytron with a rounded piceous spot at the shoulder, and a more elongate one near the

apex, these spots not extending to either margin; underside and legs pale fulvous; the last abdominal

segment of the male produced into a rounded lobe, and the preceding segment with a longitudinal

2. Iphitroides quadripunctata. (Tab. XLII. fig. 7.)

‘Flavous, the terminal joints of the antennz fuscous; head and thorax impunctate ; elytra scarcely perceptibly

punctured, each with a small round spot near the scutellum, and another at the middle, black.

Length 2-3 lines.

Hab. Mexico, Chilpancingo in Guerrero (Hoge, H. H. Smith).

This species only differs from the preceding in the markings of the elytra: the

anterior spot is placed at the basal margin near the shoulder ; the second spot is equally

small and placed nearer to the suture, at or immediately below the middle. The

antenne have the lower four or five joints flavous, the other joints fuscous. Numerous

specimens.

3. Iphitroides nigrocincta. (Tab. XLII. fig. 8.)

Pale testaceous ; the antennz (the basal joint excepted) black, each joint pale at the apex; thorax margined

with black and with a dark longitudinal stripe on the disc ; elytra scarcely punctured, testaceous, narrowly

margined with black.

Length 2-23 lines.

Hab. Mexico, Chilpancingo in Guerrero (H6ge).

In shape and structural details this species closely resembles both the preceding.

The antenne in the male are equally long, and have the basal joint entirely testaceous,

but all the other joints are of that colour at the apex only. The thorax is impunctate,

narrowly margined with black, and has a black median vitta, the latter in one

specimen extending only as far as the sulcus. The scutellum is black. The elytra

are exceedingly finely punctured, of a pale testaceous colour, and are narrowly margined

with black. The tibize are stained with fuscous at the base; the other parts of the

legs, as well as the underside, are testaceous. ‘Two specimens.

4, Iphitroides violaceipennis.

Fulvous ; the antenne (the basal three joints excepted) black ; head and thorax impunctate ; elytra violaceous-

blue, extremely minutely punctured ; legs fulvous; abdomen piceous,

Length 24 lines. |

Hab. Mexico (coll. Duvivier).

I. violaceipennis differs from the other species of the genus by the transverse sulcus

of the thorax being almost obsolete; the longitudinal grooves at the sides of the

thorax, however, are very distinct. ‘The elytra are violaceous-blue in colour; the head

and thorax are entirely impunctate; the antenne extend almost to the end of the

elytra, and are black, with the exception of the first three joints, these being fulvous ;

the posterior femora are scarcely thicker than the others.

The only specimen I have seen of this species was kindly given to me for description

by M. Duvivier.

Systena nigroplagiata (p. 324).

To the localities given, add :—Mexico, Chilpancingo, Omilteme, Amula, Tepetlapa,

Xucumanatlan, all in Guerrero (H. H. Smith) ; GuatemMaua, Duefias (Champion).

Several other varieties of this species have since been obtained at Omilteme and Chil-

pancingo; in one of these the elytra have a sutural and also a submarginal longitudinal

band, the former being widened at the base and at the middle, and the latter anteriorly

widened below the shoulder (corresponding to the small spot at the same place in the

type); in another variety the elytra are without spots, but have a narrow sutural

and also a submarginal black stripe of equal width; in another variety the elytra are

entirely testaceous, and in another they are entirely black. Of the two specimens

figured on Tab. XIX., fig. 23 is taken from an example from Duefias, fig. 24 from one

from Juquila. S. wndulata, Jac.,a specimen of which from Cerro de Plumas was figured

on Tab. XIX. fig. 22, is probably a variety of S. nigroplagiata.

According to Dr. Horn (op. cit. p. 274), 8. discicollis, 8S. capitata, and S. semivittata

are probably varieties of the widely distributed and variable S&. teniata (Say). Dr.

Horn has described the known varieties, and I have not much doubt about the

correctness of his views. JS. ¢eniata stands as a synonym of Phyllotreta vittata, Fabr.,

This very small species agrees in most of its characters with Systena, but differs

from it by the short joints of the antennz and the more transversely-shaped thorax.

Some specimens have a nearly black thorax and dark blue elytra; those from British

Honduras are entirely dark blue above, with an almost smooth head and thorax. Many

examples were obtained by Mr. Champion in Chiriqui. |

This is a large and comparatively robust species. It differs from. most of its con-

geners by the long and stout antenne, the basal joints of which are thickened, the

third longer than any of the following ones. The head is impunctate, broad, not

constricted behind the eyes; the thorax is closely and finely punctured, of the usual

shape, but with the basal groove sinuate at the middle and very distinctly marked ; the

elytra are depressed, with the basal portion somewhat swollen, extremely closely and

antenne gradually thickened towards the apex, the lower three joints piceous or dark fulvous; thorax

transverse, with straight sides, dark bluish, opaque, not or scarcely perceptibly punctured; elytra very

finely rugose, with irregular rows of punctures on the anterior portion, cupreous or bluish ; underside and

legs black, the posterior femora metallic bluish.

Hab. Mexico, Las Vigas, Jalapa (Hoge).

Separable from D. ovata by the narrow elongate shape, the opaque, nearly impunctate

thorax, the dark antenne and legs, and the finely rugose elytra. Numerous specimens

were obtained by Herr Hoge at Las Vigas.

the following joints gradually thickened; thorax short and very strongly transverse, the sides rounded,

the surface black, sparingly and finely punctured, the punctures rather larger near the base; elytra dark

metallic blue, oblong, nearly parallel, the punctures large and rather irregularly arranged near the suture,

more regularly placed at the sides, the interstices with a few minute punctures only ; underside and legs

black ; the posterior tibial spur long ; abdomen impunctate,

A single specimen.

PSEUDODIBOLIA. (To follow the genus Dibolia, p. 358.)

Body ovate, very convex ; head inserted in the thorax as far as the eyes; antenne short, the terminal joints

submoniliform, the second and third joints short, equal; thorax transverse, short; elytra convex, punctate-

striate, their epipleurs concave, extending to below the middle; posterior femora very strongly incrassate ;

posterior tibize dilated, deeply channelled, serrate on their outer edge, the apex furnished with two strong

spurs; the first joint of the posterior tarsi as long as the following joints together ; claws appendiculate ;

prosternum rather broad, slightly widened posteriorly ; mesosternum short; the first abdominal segment

as long as the following three segments together; anterior coxal cavities open.

The species for which this genus is proposed closely resembles a Homophyla or

Spheroderma, but differs from either in the armature of the posterior tibiee and in the

short submoniliform antenne. Dibolia has a double spur to the hind tibie, but the

spur is only divided at the apex; in Pseudodibolia there are two entirely separated

spurs, the inner one being longer than the other. In the present genus, moreover,

the outer edge of the posterior tibie is serrate. The sectional characters given by me

on p. 357 require modification to include this genus.

1. Pseudodibolia picea. (Tab. XLII. fig. 20.)

Piceous or black ; the basal six and the apical two or three joints of the antennx reddish-yellow, the other

joints black ; thorax finely longitudinally strigose ; elytra strongly punctate-striate, the interstices finely

punctured. ,

Head closely and finely punctured, piceous or dark fulvous, the frontal elevations absent, the clypeus with a

central ridge, fulvous, as well as the labrum; palpi scarcely thickened; antenne only extending to the

base of the elytra, reddish-yellow, the seventh to the ninth joints black, the apex of the terminal joint

concave ; thorax nearly three times as broad as long, slightly widened at the middle, the sides straight,

the anterior angles oblique and a little thickened, the surface very closely and finely longitudinally

strigose ; scutellum transverse ; elytra very convex, nearly black, rather closely and strongly punctate-

striate, the interstices minutely punctured, the apices conjointly rounded; underside and legs piceous or

dark fulvous, the first abdominal segment strongly punctured.

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

Numerous examples. Two specimens obtained by Mr. Smith at Dos Arroyos,

Guerrero, are perhaps females of the same species; they are much larger, the antenne

are longer, with three or four of the intermediate joints black, and the first joint of the

posterior tarsi is a little shorter. One of these specimens is black above, the other

entirely fulvous.

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

In its structural characters L. marginipennis agrees in every respect with the other

species of the genus, having very narrow elytral epipleure, an invisible prosternum,

open anterior coxal cavities, &c., thus forming a link between the groups Halticine

and Galerucine.

PTOCADICA (p. 360).

Ptocadica straminea (p. 360).

Additional specimens of this species have been received from Bugaba and the Volcan

de Chiriqui. These differ from the type and belong to two well-marked varieties :—

1. Elytra with a transverse band at the base and an arcuate mark at the middle piceous.

2. Elytra with a transverse band at the base only piceous.

2. Ptocadica bifasciata.

Yellowish-white ; the antenne, breast, and apex of the femora, and the tibiee and tarsi, black; thorax and

elytra impunctate, the latter with a transverse band at the base and another below the middle, black.

much larger than the others, and has the third and fourth and the apical two joints of

the antenne only flavous; the elytra flavous, with a metallic gloss, and more distinctly

depressed below the base. It is probably a variety of the same species.

straight, the anterior angles oblique, the surface remotely and strongly punctured; elytra with a distinct

depression below the base, strongly-punctured in closely approached rows.

Hab. Panama, Volcan de Chiriqui (Champion).

The coloration and the remotely punctured, transversely shaped thorax are the

principal marks of distinction of this species. The female is considerably larger than

the male, and has the thorax still more transverse and coarsely punctured. The

prosternum is broad and impunctate. ‘Two specimens.

Hab. Mexico, Amula in Guerrero (H. H. Smith).

The transverse, impunctate thorax and the minutely punctured elytra in connection

with the system of coloration principally distinguish A. amulensis from its congeners.

It is also of much more elongate parallel shape than is usual in this genus.

nearly as long as the body, fulvous, the terminal joints more or less fuscous, the third joint longer than

the second, the fourth longer than the third; thorax about one half broader than long, slightly narrowed

in front and at the base, the surface very finely punctured ; elytra elongate, but little wider at the base

than the thorax, the shoulders rounded, the surface very closely and finely punctured, the suture

narrowly piceous, this colour slightly extended posteriorly ; posterior femora infuscate.

Hab. Mexico, Cuernavaca in Morelos, Xucumanatlan, Amula, and Chilpancingo in

Guerrero (H. H. Smith), Guanajuato (Sallé).

Apparently the commonest species of the genus in Mexice. It may be chiefly distin-

guished by the long antenne, the finely punctured thorax, and the dark suture of the

elytra. L. occidentalis is exceedingly like several European species. A large number

of specimens were obtained by Mr. Smith.

PALAOTHONA. 301

PALEOTHONA (p. 377).

Palzothona guatemalensis (p. 377).

To the localities given, add :—Mexico, Rincon in Guerrero, Atoyac in Vera Cruz

Elongate, fulvous; the antenne (the first joint excepted), tibie, and tarsi black; the head and thorax fulvous ;

* elytra dark blue, more or less closely and strongly punctured ; legs piceous.

Var. Legs partly or entirely fulvous.

Length 13-2 lines.

Hab. Mexico, Tupataro (Sallé).

Very closely allied to P. guatemalensis, but evidently distinct therefrom. Larger

and much more elongate in shape; the antenne entirely black, or black with the first —

joint fulvous ; the head and thorax impunctate; the elytra not swollen at the base,

their punctuation very variable—in some specimens very fine, in others much stronger,

and arranged in very close semi-regular rows. ‘The first joint of the anterior tarsi is

dilated in the male. Four specimens.

2 (s). Paleothona imitans.

Below black; the head, the basal joints of the antenne, the thorax, and the anterior legs fulvous; thorax

impunctate ; elytra violaceous-blue, strongly and closely punctured.

Length 14 line.

Head broad, impunctate, the eyes very large, the frontal tubercles scarcely indicated, the carina short and

distinct ; antenne nearly extending to the apex of the elytra, the basal two joints and part of the third

fulvous, the rest black, the fourth joint much longer than the third; thorax transverse, slightly narrowed

at’ the base, the sides rather evenly but not strongly rounded, the surface impunctate, slightly depressed

in front of the scutellum ; the latter black ; elytra gradually widened posteriorly, rather swollen at the

base, strongly punctured in closely arranged rows; anterior legs and the base of the posterior femora

fulvous, the anterior femora with a dark streak on their upper edge.

Hab. Mexico, Xucumanatlan in Guerrero (H. H. Smith).

Two specimens. In the strong elytral punctuation this species approaches P. guate-

malensis. It differs from that insect, however, by the antenne being much longer,

and with the fourth joint distinctly longer than the third ; the thorax evenly rounded

at the sides (instead of being considerably widened at the middle); and the legs

differently coloured.

3 (a). Palwothona flavicollis.

Flavous ; the thorax transverse, impunctate; scutellum black; elytra bright metallic green, closely and finely

punctured ; the breast and abdomen black.

Length 1 line.

Head deeply punctured round the eyes, the middle portion smooth, the frontal elevations broad and distinct,

sides rounded at the middle, the anterior angles slightly thickened, the surface pale flavous, impunctate,

with a shallow transverse depression on each side near the base ; scutellum black ; elytra slightly broader

at the base than the thorax, metallic green, extremely finely and closely punctured, the interstices some-

what finely aciculate ; the underside of the thorax and the legs pale flavous; the breast and abdomen

black, shining.

Hab. Panama, Volcan de Chiriqui (Champion).

This species resembles P. longicornis in colour; but the antenne are shorter and

entirely flavous; the elytral punctuation is much finer; the head, thorax, and legs are .

lighter in colour ; and the general size is smaller. Three specimens.

5 (a). Paleothona smithi.

Black ; the head, the basal joints of the antenne, the thorax, and legs (the posterior femora excepted) fulvous ;

elytra metallic green, closely and semi-regularly punctured.

Length 17-13 line.

Of rather convex shape; the head impunctate, fulvous, the frontal elevations flat, somewhat indistinct ; antenne

rather stout, scarcely extending to the middle of the elytra, black, the basal five joints fulvous, the third

and following joints of equal length; thorax one half broader than long, the sides evenly and rather

strongly rounded, the surface with a few very minute punctures, and a depression in front of the

scutellum; the latter black or piceous; elytra rather convex, metallic green, distinctly punctured in

irregular rows, the shoulders prominent; legs fulvous, the posterior femora piceous ; the first joint of the

posterior tarsi as long as the following joints united.

Hab. Mexico, Xucumanatlan and Omilteme, both in Guerrero (H. H. Smith).

Differing from all its congeners, P. longicornis excepted, by the somewhat convex

shape of the elytra and their metallic green colour ; also by the rather robust antenne,

which have their third and following joints equal. P. smithi is also allied to P. semi-

fulva, but it may be known from that insect by the dark scutellum and underside.

9, Paleothona nigricollis.

Elongate, black; the head and thorax impunctate; elytra metallic greenish-blue, closely and strongly punc-

tured.

Length 12 line.

Hab. GuateMata, Calderas on the slope of the Volcan de Fuego 7000 feet (Cham-

pion).

A single specimen. This insect differs from any of its allies by the black head,

thorax, antenne, and legs in connection with the strongly and evenly punctured elytra;

the antenne are slender and elongate, the third and fourth joints equal; the thorax

has a deep fovea in the middle at the base; the elytra have no basal elevation, and are

of a metallic greenish colour, the punctuation being distinct to the apex.

10, Paleothona viridis,

Black; the basal three joints of the antenne, and the tibie more or less, fulvous ; thorax greenish-black,

minutely punctured ; elytra metallic green, closely punctured and finely rugose.

Length 1 line.

PALZOTHONA. 303

Elongate, slightly widened posteriorly; the head broad, impunctate, very finely granulate, the frontal

tubercles small; antenne two-thirds the length of the body, black, the basal three joints fulvous, the

third joint only one half longer than the second, and much thinner than it, the fourth longer than the

third ; thorax short, transverse, the sides slightly rounded, the anterior and posterior margins straight,

the latter with a depression in front of the scutellum, the surface minutely granulate and punctured,

greenish-black, not very shining ; scutellum greenish-black, pointed behind ; elytra metallic green, closely

and rather strongly punctured, the interstices finely rugose ; below and the femora blackish; the knees

and the tibie and tarsi more or less fulvous.

Hab. Panama, Volcan de Chiriqui 8000 feet (Champion).

Quite distinct from most of its congeners by the system of coloration and sculpture ;

and from P. nigricollis by the finely punctured thorax and the rugose elytral interstices.

The antenne are shorter in the female than in the male. Found in some numbers by

Mr. Champion, in a bamboo-thicket on the slope of the Volcan de Chiriqui at a high

elevation.

11. Paleothona godmani.

Black ; the antenne long and slender (¢); the head and thorax impunctate ; elytra metallic blue or greenish,

finely and semi-regularly punctured ; legs black, the tarsi sometimes obscure fulvous.

Length 1-14 line.

Hab. Mexico, Teapa in Tabasco (H. H. Smith) ; GuateMata, Chiacam in Vera Paz

(Champion). |

Of elongate, posteriorly slightly widened, shape ; the antenne black, with the third

joint only a little longer than the second, the fourth twice the length of the third, and

the other joints equal in length; the thorax rather convex, about one half broader

than long, entirely impunctate, black, very shining ; the elytra metallic blue, finely

punctured, the punctures remotely placed and arranged in semi-regular rows. This

species is principally distinguished amongst its allies by the black head and thorax.

The female is considerably larger than the male, and has much shorter antenne.

P. godmani resembles P. nigricollis in colour, but it is much smaller and has the elytra

finely (instead of strongly and rugosely) punctured.

12. Palzothona dilaticornis.

Fulvous ; antenne robust; head and thorax impunctate ; scutellum piceous ; elytra metallic green, strongly

and closely punctured.

Length 13 line. .

Head rather broad, fulvous, impunctate, the frontal elevations strongly raised, subquadrate; antenne more

than two-thirds the length of the body, entirely fulvous, the joints slightly dilated, the third and fourth

triangularly widened, nearly equal, the following joints more elongate; thorax rather convex, one half

broader than long, the sides evenly rounded, the angles not prominent, the surface impunctate, fulvous;

elytra much wider at the base than the thorax, metallic green, the punctures strong and placed in close

rows, less distinct at the apex ; underside and legs fulvous, the breast and abdomen slightly stained with

fuscous at the sides ; the first joint of the posterior tarsi as long as the following joints together.

Hab. Mexico, Jalapa (Hége).

A single specimen only, a male, of this species has been received. It may be known

by the long and robust antenne in connection with the system of coloration.

CHRYSOGRAMMA (p. 380).

2. Chrysogramma trifasciata. (Tab. XLII. fig. 12.)

Obscure fulvous; the thorax with a metallic sneous gloss, finely punctured; elytra blackish-bronze, with

three narrow angulated flavous fascie, very closely and finely punctured ; underside and the base of the

posterior femora spotted with greenish-zneous.

Length 23 lines.

_ Hab. Mexico, Yolotepec (Sal/é).

One example. C. trifasciata differs from C. octomaculata and the following two

species by the fulvous antenne and the system of coloration of the elytra; the fasciz

of the latter are arranged thus—one a little below the base, with three branches

extending upwards to the base (so as to enclose two spots of the ground-colour on

each elytron), one just before the middle, connected with the first at the sides and

slightly extended along the suture, and one before the apex, the latter deeply excised

posteriorly and in the form of an arcuate mark on each elytron.

3. Chrysogramma (?) septempunctata, (Tab. XLII. fig. 13.)

Broad, oblong-ovate, flavous ; the antenne, tibie, and tarsi black; head and thorax fulvous, sparingly punc-

tured ; elytra closely punctured, flavous, each with seven small black spots (1.2.2.2).

extending to the middle of the elytra, black, the third and fourth joints equal, the fifth a little longer

than the fourth ; thorax transverse, the anterior margin straight, the posterior one strongly rounded, the

sides rounded at the middle, the anterior angles slightly produced and each with a single seta, the surface

dark fulvous, sparingly and irregularly punctured, with an obsolete depression near the anterior angles,

and a still more obsolete transverse groove near the base; scutellum broad, piceous; elytra closely and

rather finely punctured, flavous, a spot at the shoulder, two spots before, two below the middle, and two

others near the apex, placed transversely in pairs, black—of these, the first spot near the suture forms

with the corresponding spot on the other elytron a cruciform mark, extending upwards to the base and

downwards for a short distance along the suture; epipleure broad, transversely wrinkled; underside

flavous, the sides of the breast, the knees, tibie, and tarsi black ; tibia mucronate; last abdominal seg-

ment fulvous, that of the male with a projecting tooth in the middle.

Hab. Mexico (Salié). ;

This species has a spine at the apex of all the tibiz, and the angles of the thorax

pointed and slightly produced (instead of being obtusely oblique); nevertheless, it is

inadvisable to separate it from Chrysogramma. Three specimens.

4, Chrysogramma (?) omiltemia. (Tab. XLII. fig. 14.)

Oblong, testaceous ; the vertex, antenne, knees, tibie, and tarsi black ; thorax with seven spots (4.3); elytra

punctured in irregular rows, testaceous,,each with a spot at the shoulder, two spots before and two below

palpi black ; antenne nearly extending to the end of the elytra, black; thorax twice as broad as long,

the sides rounded, the anterior angles slightly tuberculiform, the surface very sparingly punctured,

testaceous, with seven spots placed transversely in two rows; scutellum black; elytra strongly punctured

in irregular rows, a spot at the shoulder, another immediately below it on the lateral margin, a trans-

verse mark below the scutellum across the suture, two almost confluent spots on each elytron below the

middle, and two smaller and more rounded ones near the apex, black; below pale fulvous, a spot on the

flanks of the thorax and another on the anterior cox black; the femora on their upper edge near the

apex, and the tibie and tarsi, black; tibiee mucronate; the last abdominal segment of the male deeply

excavated, the apex in the form of a broad lobe, the anterior edge of which is sinuate.

Hab. Mexico, Omilteme in Guerrero (A. LT. Smith).

This species agrees with the preceding in having all the tibis mucronate; it also

has the elytra very similarly marked, but their punctuation is arranged in irregular

rows. The antenne are very long; the first joint of the anterior tarsi is broad; the

excavation of the last abdominal segment in the male is very large, and occupies the

greater portion of its surface.

5. Chrysogramma pictipennis. (Tab. XLII. fig. 15.)

Black, the head fulvous, the basal joints of the antenne and the thorax flavous; elytra very finely and closely

punctured, flavous, all the margins, a spot at the shoulders, two spots below this, one near the apex, and

an angulate longitudinal stripe extending from the middle of the disc to the lateral margin, black.

Var. The elytral spots and stripe more or less coalescent.

broader than long, narrowed in front, the sides nearly straight and narrowly margined, the anterior

angles obliquely rounded, the surface finely and closely punctured, the interspaces minutely rugose ;

scutellum broad, black: elytra moderately convex, nearly parallel, very finely punctured, the interspaces

markings—a subtriangular spot at the apex and’ another below the shoulders (connected with the lateral

stripe), a spot on the basal margin, two spots placed one behind the other below the shoulders (the lower

one larger than the upper.one), a narrow longitudinal stripe extending from the middle of the disc down-

wards for a little distance and forming an angle where it joins the lateral stripe (the angulate portion

being much broader than the longitudinal one), and a spot near the suture towards the apex; underside

and legs black.

Hab. Mexico, Ventanas in Durango (Hoge).

— Not unlike C. 8-maculata, Jac., but with the elytra differently marked, and the

underside and legs black. Fourteen specimens.

_ NOTOZONA (p. 382).

Of the five species of Wotozona from Mexico or Honduras described by Clark, four

have been figured by Mr. Waterhouse in his “ Aid to the Identification of Insects,” 11.

t. 167—W. elegans (fig. 4), WV. humilis (fig. 5), WN. rufofusca (fig. 6), and N. sparsa

Blepharida may prove to be varieties of one or other of these; but till further material

is obtained, it is impossible to speak with any certainty. I have already stated my

opinion (huj. op. p. 384) that W. sparsa ought to be placed in Blepharida.

BLEPHARIDA (p. 385).

12. Blepharida alternata. (Tab. XLII. fig. 18.)

Fulvous, the apical joints of the antenne fuscous ; thorax very finely punctured, with several depressions ;

elytra geminate-punctate-striate, pale flavous, the dise Jongitudin ally striped with fulvous, the shoulders

with an oblong darker spot.

some distance from the inner margin of the eyes, less than half the length of the body, fulvous, the last

three or four joints fuscous, the third and fourth joints equal, the fifth the longest, the following joints

shorter; thorax nearly three times as broad as long, the sides almost straight, the anterior margin

concave, the surface with a few punctures at the sides only and two fovee at the same place; elytra

convex, deeply and closely gemminate-punctate-striate, the disc fulvous, this colour divided by very narrow

longitudinal pale flavous stripes, the sutural and lateral margins more broadly of that colour, the shoulders

with an oblong obscure fulvous spot.

Hab. Mexico, Xucumanatlan in Guerrero (H. H. Smith).

A single specimen.

CYRSYLUS. (To follow the genus Pseudogona, p. 391.)

Ovately-subquadrate ; antenne filiform, the terminal joints slightly thickened ; palpi slender; eyes large ;

thorax transversely subquadrate, without transverse sulcus; elytra punctate-striate ; tibie simple, the

posterior pair mucronate ; prosternum rather broad, flattened, longer than broad ; anterior coxal cavities

closed ; claws appendiculate.

This genus is proposed for several small species which agree in some respects with

Systena, but differ from it by the thorax being without trace of a transverse sulcus, and

by the elytra being punctate-striate; the eyes are also larger than in Systena, and the

thorax is scarcely broader than long and of different shape. C. recticollis appears to be

one of the commonest and most widely distributed species of Halticine in Central

America.

1. Cyrsylus recticollis. (Tab. XLII. fig. 16.)

Black or piceous ; the antenne and the four anterior legs more or less fulvons ; ; the head impunctate ; the

thorax extremely finely punctured, subquadrate; elytra finely and regularly punctate-striate.

slightly shorter than the preceding, the terminal one acutely pointed; thorax subquadrate, about one half

broader than long, the sides strongly rounded, the angles slightly thickened, the posterior ones somewhat

oblique, the surface impunctate, fulvous, the base with a slight depression in front of the scutellum ; the

latter piceous ; elytra wider at the base than the thorax, metallic green, with a slight brassy gloss, strongly

and closely punctured in double rows near the suture, singly so at the sides; underside and legs fulvous ;

abdomen piceous, the last’ segment with a central furrow; anterior coxal cavities closed ; the first joint

of the posterior tarsi as long as the following joints united.

Hab. Guatema.a, San Gerdénimo (Champion).

A single male specimen, at once distinguishable by the length and structure of the

antenne. C. crassicornis is extremely like some of the species of Palcothona, and it

has a depression at the base of the thorax in the centre as in that genus; the closed

anterior coxal cavities will separate it, however, from Palwothona.

8. Cyrsylus fulvipes.

Fulvous; the head and thorax impunctate, the sides of the latter rounded ; elytra bluish-black, finely punctate-

striate, with a slight depression below the base.

Length 13 line.

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

In this species, which resembles in all its essential characters the preceding one, the

sides of the thorax are rounded, not straight; the thorax itself is scarcely one half

broader than long, rather convex, impunctate ; the elytra are regularly and finely

punctate-striate, bluish-black ; the underside and legs are entirely fulvous. The male

has a very narrow longitudinal groove on the middle of the last abdominal segment.

Euplectroscelis, huj. op. p. 892 (nec Crotch).

Dr. Horn has been kind enough to send me a typical example of Euplectroscelis

zanti, Crotch, which proves that both Baly and myself have wrongly identified Crotch’s

genus. All the species described in this work under the generic name of Euplectro-

scelis belong to Homophyla. A single species, from Peru, was referred to Homophyla

by its author.

HOMOPHYLA. | 809

1 (a). Homophyla nigrita.

Ovate, very convex, piceous, above black; the three basal joints of the antenne, and the terminal joint also,

fulvous; the head and thorax impunctate; elytra rather distantly punctate-striate, the apex nearly

impunctate ; the anterior legs fulvous.

Var. Entirely obscure fulvous.

Length 1 line.

Hab. Muxico, Teapa in Tabasco (H. H. Smith).

This small species differs from H. variabilis by its general smaller size, the colour of

the antenne, and the more distinct and more scattered elytral punctuation ; these

characters are constant in the numerous specimens obtained. H. variabilis also occurs

at 'Teapa.

1 (zs). Homophyla fulvifrons.

Piceous or black, the head, antennw, and anterior legs fulvous ; thorax extremely closely and finely punctured ;

elytra finely and regularly punctate-striate.

Length 1-1} line.

Head very finely and rather closely punctured, fulvous, without frontal tubercles, the carina distinct, broad ;

antenne scarcely half the length of the body, entirely fulvous, the second and third joints small, equal,

the others slightly longer and thickened; thorax more than twice as broad as long, narrowed in front,

the sides straight, the surface extremely closely and finely punctured; elytra regularly and distinctly

punctate-striate, the strie rather widely separated; posterior tibia deeply sulcate, with the usual acute

tooth below the middle; the first joint of the posterior tarsi rather longer than the other joints together.

Hab. Mexico, Xucumanatlan in Guerrero, Atoyac in Vera Cruz (H. H. Smith).

This insect seems to differ from all the numerous varieties of H. variabilis, and also

from H. nigrita, by the fulvous and closely punctured head, the fulvous antenne, and

the regularly and remotely punctured elytra. The male is of subparallel, somewhat

cylindrical shape, the female being more broadly, ovate. Two specimens, one of each

sex, were obtained at Atoyac; a female of much larger size, but not differing in any

other way, was captured at Xucumanatlan.

visible under a strong lens; elytra comparatively strongly and closely punctured in rows; legs piceous

or black, the coxee and the knees more or less dark fulvous ; posterior tibize strongly dilated beyond the

middle, toothed before the apex; prosternum impunctate.

Hab. Panama, Bugaba in Chiriqui (Champion).

SPHRODERMA. (To follow the genus Homoply/a, p. 393.)

Spheroderma, Stephens, Il. Brit. Ent., Mand. iv. p. 328 (1834).

Spheroderma, confined, so far as our knowledge goes, almost entirely to the Old

World, has a single species in North America. . The only representative of the genus

obtained by Mr. Champion does not seem to differ structurally from the European

forms, except in its more oblong (instead of rounded) shape and metallic blue

coloration.

PHYDANIS. (To follow the genus Spheroderma.)

Phydanis, Worn, Trans. Am. Ent. Soc. xvi. p. 198 (1889).

This genus has very little affinity with any of the known groups of Halticine. Its

-author places it in the Aspicelites of Chapuis; but in this I cannot agree with him,

the shape, structural characters, punctuation, &c., being quite foreign to that group.

Dr. Horn, in his diagnosis of the group “ Aspicele” (op. cit. p. 195), gives the antenne

PHYDANIS.—PSYLLIODES. ~ 3511

as ten-jointed: this is evidently a misprint, as both Aspicela and Phydanis have these

organs eleven-jointed.. A single species is now added from Mexico; it is closely allied

to the North-American P. bicolor,

1. Phydanis nigriventris, (Tab XLII. fig. 23.)

Black, the head, antennae, thorax, and legs fulvous; elytra metallic violaceous-blue, punctate-striate, the inter-

stices finely punctured.

Length 1 line.

Head broad, the vertex convex and with a few fine punctures, the frontal tubercles broad, not strongly raised,

the space below the eyes deeply excavated for the reception of the basal joint of the antenne; the antenne

extending to two-thirds the length of the elytra, fulvous, rather robust, the third joint slightly longer than

the fourth; thorax transversely convex, nearly three times as broad as long, the sides rounded, the angles

obtuse, the posterior margin sinuate on each side, the surface very minutely and finely punctured, fulvous ;

scutellum black; elytra short, subcylindrical, convex, dark blue, distinctly punctate-striate, the interstices

minutely punctured ; underside (that of the thorax excepted) black; legs fulvous; the tibice deeply

channelled ; claws appendiculate ; anterior coxal cavities open.

Hab. Mexico, Chilpancingo and Amula, both in Guerrero (H. H. Smith).

Two specimens. This species resembles P. décolor, Horn, in the coloration of the

upper surface; but. it differs from it in having the underside black, and the elytra

strongly punctate-striate, the punctures distinct to the apex. P. nigriventris is not

unlike Gastrophysa polygont in its general facies, though it is very much smaller than

that insect.

-PSYLLIODES (p. 393).

This genus possesses closed (not open) anterior coxal cavities, and it must therefore

be placed in the same section as Chetocnema &c. Weise gives the claws as appendi-

culate, in opposition to Chapuis.and Horn, who describe them as simple; they are

certainly simple in the American species which have come under my observation.

3. Psylliodes mexicana.

Below black, above bronze-coloured ; the basal joints of the antenne and the tibie more or less fulvous ; thorax

very strongly and closely punctured ; elytra deeply punctate-striate.

A Psylliodes obtained by Mr. Smith at Omilteme agrees very well with Dr. Horn’s

description of P. sublevis. It has the head almost impunctate; the thorax extremely

finely and sparingly punctured on the disc, more closely so at the sides, and with a

slightly raised central ridge (of this Dr. Horn makes no mention) ; the elytra finely and

rather remotely punctured, the punctures becoming almost obsolete below the middle;

thorax finely and closely punctured; elytra finely punctate-striate, the interstices flat and impunctate.

Length # line.

‘Hab. Mexico, Omilteme in Guerrero (H. H. Smith).

A single example. In this species the head is entirely impunctate, the labrum and

antennz are fulvous, and the thorax, as in C. smithi, has not oblique anterior angles,

the latter being, however, slightly thickened. It differs from C. smitht in having the

thorax much more closely and finely punctured, and with a row of very fine punctures

along the basal margin; the elytra are also more finely punctured, and the interstices

are flat throughout.

14. Chetocnema interstitialis. |

Oblong-ovate, robust, dark bronze-coloured, the basal joints of the antenne, the tibie, and tarsi pale fulvous ;

on the disc; elytra with regular and deeply punctured striz, the interstices extremely finely punctured,

the punctures on each arranged in a single row; prosternum closely punctured, the abdomen more

sparingly so.

and C. transversicollis, differing from the former by the densely punctured, rugose

clypeus, the broader thorax, the sides of which are more rounded, and the punctate

elytral interstices; and from the latter by the deeply punctured head and flat elytral

interstices. From the allied C. denticulata (Ill.), the brighter bronze-colour and the

less closely and strongly punctured head and thorax sufficiently distinguish it.

15. Cheetocnema horni.

Ovate, black, the antenne, tibie, and tarsi flavous; head impunctate; thorax transverse, the anterior angles

oblique, the surface finely and closely punctured ; elytra with a slight eneous lustre, strongly punctate-

striate, the interstices rather convex, impunctate.

Length 3 line.

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

This small species seems to resemble in many respects C. quadricollis, Schwarz, and

C. decipiens, Lec., but differs from both these in usually having all the femora dark

and the elytral interstices impunctate. The head is rather opaque, without any trace

of punctuation ; the thorax may be described as transversely convex, with the sides

very nearly straight and not converging in front, and the base without marginal line ;

the elytra are widened towards the middle, their interstices rather strongly convex and

impunctate. In some specimens the four anterior femora are almost entirely flavous. —

less distinct smooth central space ; elytra deeply punctate-striate, the punctures closely placed, the short

subsutural row straight, the interstices entirely impunctate ; tibise and tarsifulvous ; prosternum strongly

narrowed between the coxte,

Hab. Mexico, near the city (Hoge).

Closely allied to C. gravida, Baly, but smaller, and differing in the straight (not

rounded) sides of the thorax. From C. denticulata (Ill.), it may be distinguished by

the shining and much more strongly punctured head, and the different shape of the

thorax. .

six joints fulvous, the others black ; thorax twice as broad as long, the sides straight, the anterior angles

thickened and slightly oblique, the surface very closely and finely punctured, the interspaces minutely

granulate ; elytra slightly depressed near the suturé, deeply striate, the punctures within the strise very

closely placed and sometimes obsolete, the interstices strongly costate.

The thorax in this species is not at all narrowed in front, but of even width; this

character in connection with the costate elytra will help to distinguish C. costati-

pennis.

Dr. Horn (Trans. Am. Ent. Soc. 1889, p. 196) sinks the name Asphera as a synonym

of this genus, and perhaps rightly so; there is, however, always the distinguishing

character of the white frontal patch present in Homopheta (unless the entire head is

pale, as in some species), which I have never observed in Asphewra. For the present I

prefer to retain the two genera as distinct, Homopheta possessing but few, Asphera a

great many, species. I may here remark that the name Asphera is five years older

than Homopheta, and that if they are put together the first-mentioned name should be

retained.

This species, at first sight, closely resembles H. wquinoctialis, but differs from it in

the following particulars: the antenne are much shorter, only reaching a little beyond

the base of the elytra, all the joints being much less elongate; the elytra are more

depressed, and the spots (although similarly placed) are more elongate and often partly

confluent. |

In the var. 6 the elytra are entirely metallic blue.

The system of coloration, the characteristic fulvous frontal patch, the scarcely mar-

gined thorax, and the structure of the posterior tarsi are the chief characters of this

Homopheta, of which two specimens were obtained. It cannot be mistaken for the

blue variety of H. simulans, as it is very much wider, has a more transversely shaped

thorax, and is black (instead of fulvous) below.

Hypolampsis, Clark, Cat. of Halticide, p. 280 (1860).

More than thirty species have been placed in this genus by Clark. Its principal

distinguishing characters are the subquadrate thorax, the incrassate palpi, the single

spine to the posterior tibia, and the appendiculate claws.

Length 32 lines. .

Head longitudinally grooved in the middle in front, with a blackish patch on the vertex, the latter strongly

rugose, the rest of the surface pale fulvous; labrum and palpi black; antenne extending to about the

middle of the elytra, black, the apical joint fulvous, the third and fourth joints equal, the seven basal

tarsi as long as the following two joints together.

Hab. Mexico, Ventanas in Durango (I/ége).

A species easily known by the seven-spotted thorax and the variegated legs. It

agrees with Coraia in having the third and fourth joints of the antenne equal in length ;

the epipleurz, however, are prolonged beyond the middle of the elytra, and the surface

of the latter is glabrous and rugose. Numerous examples.

as the following two joints together ; claws bifid.

Hab. Mexico, Matamoros Izucar and Atlixco, both in Puebla (Hége).

N. longicornis might easily be mistaken for Coraia maculicollis. It is, however, less

robust; the structure of the antenne is different; and the elytra have no trace of the

bluish hue peculiar to Coraia. The female is more dilated posteriorly, and the antenne

in this sex are, as usual, shorter.

T. vicina is very closely allied to 7. variabilis, and is equally variable as regards the

colour of the elytra; it differs from it in the following particulars :—The antenne are

less robust, the thorax is much more strongly (almost rugosely) and closely punctured,

and the elytra are more distinctly rugose (in 7. variabilis they are extremely finely

coriaceous), and have three or four obsolete (sometimes more distinctly marked)

longitudinal ridges. In some specimens the spots on the thorax are confluent. The

elytra are similarly pubescent in both species. Numerous examples.

T. guatemalensis varies greatly in the colour of the elytra; the latter are coria-

ceous throughout, but more strongly so than in the other members of the genus from

our region. ‘This character in connection with the unspotted thorax will assist in the

recognition of the present species. Many specimens.

130 (a). Diabrotica quatuordecim-punctata. (Tab. XLITI. fig. 14.) |

Black, the antenn and legs fulvous ; the head testaceous; thorax testaceous, with four black spots ; elytra

closely punctured, testaceous, each with seven black spots (1, 2, 2, 2).

Length 3 lines.

Head with a deep fovea on the vertex, the latter with two black spots; the antenne extending to the middle

of the elytra, fulvous, the third joint twice as long as the second, the fourth much longer than the pre-

ceding one; thorax one-half broader than long, the sides rounded anteriorly, the surface impunctate, with

suture a little lower down, and two near the apex, placed transversely ; underside black ; legs fulvous.

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

A single specimen. The elytral spots are placed in two longitudinal rows, the four

outer spots at equal distances near the lateral margin, and the three inner ones at

‘unequal distances near the suture. In the position of the spots the present species

differs from any of its congeners in this section.

Diabrotica nitidula (p. 563).

granulate and finely rugose; underside piceous ; legs fulvous, the posterior tibie and the tarsi nearly

black. .

Hab. Mexico, Acapulco in Guerrero (Hége), Yautepec in Morelos (Flohr).

The head and the underside vary in colour. The long third joint of the antenne,

and the blackish, opaque, and slightly rugose elytra are the chief characters of this

species.

Diabrotica longitarsis (p. 567).

To the localities given, add :—Mexico, Jalapa (MZ. Trujillo).

159 (a). Diabrotica ribbei.

Black; antenne fulvous, the third joint elongate; thorax flavous, depressed at the sides, impunctate; elytra

finely and irregularly punctured, flavous, a spot on the suture at the base and the posterior third black.

Length 2 lines,

~DIABROTICA.—AGELASTICA. 333

Hab. Panama, Chiriqui (coll. Jacoby).

D. ribbei may be chiefly recognized by the pattern of the elytra. The head is

impunctate; the antenne extend to the middle of the elytra, and have their fourth

joint slightly longer than the third, both being of elongate shape ; the thorax is nearly

twice as broad as long, impunctate, and with a distinct fovea on each side; the elytra

are finely and not very closely punctured, and the sutural spot surrounds the scutellum,

the entire posterior third being black and shining; the underside and legs are black,

the extreme base of the femora having a yellow spot. A single specimen.

165. Diabrotica (?) antennata. (Tab. XLIII. fig. 15.)

Black ; the antenne, head, thorax, and legs fulvous; thorax bifoveolate, impunctate ; elytra finely punctured,

flavous, the suture anteriorly, a sublateral band, and three spots placed longitudinally near the suture,

black.

d. Face excavated anteriorly; the third joint of the antenne very elongate, and thickened towards the

apex.

Length 23 lines.

Hab. Mexico (Sallé, ex coll. Sturm).

Of this curious species there is a single specimen in Sallé’s collection; it is labelled

Diabrotica scutellata, Sturm. The claw-joints being all broken off I am unable to say

whether the species really belongs to Diabrotica. The head is transversely excavate at

its lower portion ; the palpi are strongly incrassate ; and the antenne have their third

joint extremely long and gradually thickened, the other joints being comparatively

short. The thorax is about one-half broader than long, impunctate and bifoveolate.

The sutural stripe of the elytra extends to one-third of their length and is pointed at

its apex ; the lateral band does not quite reach the apex and is indented at the middle ;

of the three spots placed near the suture, the first is small and antemedian, the second

is large, ovate, and placed below the middle, and the third is elongate and does not

extend to the apex.

AGELASTICA. (To follow the genus Diabrotica, p. 569.)

Agelastica, Redtenbacher, Fauna Austriaca, ed. 1, p. 525 (1849).

I refer, with some doubt, a single species from Mexico to this genus, which contains

but few representatives, and has not hitherto been recorded from our region. In the

Mexican insect, however, the tibie are all armed with a spine, the first joint of the

posterior tarsi is as long as the following two joints together, the claws are appendicu-

late, and the anterior coxal cavities are open. In its general shape and appearance

A. viridis differs considerably from the European A. aini.

334 PHYTOPHAGA.—SUPPLEMENT.

1. Agelastica viridis.

Fulvous, the antenne piceous; thorax subquadrate, shining, impunctate ; scutellum black; elytra metallic

green, finely and closely punctured, the interstices here and there minutely wrinkled.

Length 2 lines. .

Of elongate, parallel shape; the head impunctate, fulvous, the vertex with a faint metallic gloss, and a more

or less distinct dark central spot, the frontal elevations narrowly oblique ;. the clypeus in the shape of a

triangular ridge; the palpi slender, piceous; the antenne rather widely separated at their point of

insertion, scarcely extending to the middle of the elytra, piceous, the lower three or four joints fulvous,

the third joint one-half longer than the second, the following joints slightly longer than the third and

nearly equal ; thorax about one-half broader than long, rather convex, the sides slightly constricted at the

base and rounded before the middle, the anterior angles in the shape of a small tubercle, and furnished

with a single seta, the surface shining, impunctate, fulvous; elytra a little wider at the base than the

thorax, with a scarcely perceptible post-basal depression, rather convex and parallel, metallic green, very

closely and finely punctured, the interstices minutely granulate and transversely wrinkled, the epipleure

distinct. nearly to the apex; underside and legs fulvous, the breast metallic greenish at the sides; all

the tibise mucronate; the prosternum not visible between the coxe.

Hab. Mexico, Chilpancingo and Acapulco, both in Guerrero (Hége).

-PSEUDODIABROTICA. (To precede the genus Microbrotica, p. 569.)

Elongate; antenne long and slender; the thorax quadrate, with two oblique depressions ; elytra narrow,

very long and slender: the intermediate and posterior tibize mucronate; the first joint of the posterior

tarsi as long as the following joints together ; claws bifid ; anterior coxal cavities open.

This genus is proposed for a single species from Western Mexico. Pseudodiabrotica

possesses nearly all the structural characters of Diabrotica, but is narrower and more

slender. The legs are more elongate than is generally the case in Diabrotica, and the

first joint of the posterior tarsi is much longer than in that genus. The male is further

distinguished by the curious excavation at the apex of the elytra.

1. Pseudodiabrotica metallica, (Tab. XLIII. fig. 16, ¢.)

Black, above metallic green; head and thorax impunctate; elytra finely punctured, the interstices here and

there transversely wrinkled.

¢. Elytra with a deep longitudinal excavation before the apex, and the surface in front of this swollen, the

apex itself pointed.

Length 2-24 lines.

¢. Head impunctate, the frontal elevations small and indistinct, the clypeus with a strongly raised central

ridge extending between the point of insertion of the antenne ; the penultimate joint of the palpi incras-

sate, the apical joint acutely pointed ; antenne black, extending to the middle of the elytra, all the joints

(with the exception of the second) long and slender, and of nearly equal length ; thorax slightly broader

than long, the sides coverging towards the base, the anterior angles furnished with a small tubercle and a

single seta, the surface rather flat, metallic green, impunctate, and with a deep oblique fovea on each side

the anterior and posterior margins straight; scutellum black; elytra narrowed posteriorly, wider at the

base than the thorax, the shoulders scarcely prominent but distinct, the surface metallic green, finely and

closely punctured in irregular rows, the interstices minutely granulate, the apex with a deep longitudinal

excavation, and the surface in front of this much swollen; legs black, slender, elongate.

Hab. Muxico, Omilteme and Chilpancingo, both in Guerrero (H. H. Smith).

In the female the elytra are devoid of the apical excavation.

Dr. Horn has kindly given me a specimen of Phyllobrotica livida, Lec., and it proves

to belong to the species described by myself under the name of Triarius mexicanus. ‘The

insect is incorrectly referred to Phyllobrotica by Leconte, the tibiz being mucronate

NEOBROTICA (p. 571).

22. Neobrotica pallida.

Pale fulvous, the antenna, tibie, and tarsi black; thorax with a deep transverse depression, impunctate ;

elytra pale fulvous, impunctate.

23. Neobrotica ruatanez. (Tab. XLIII. fig. 17.)

Fulvous, the antennz (the lower two joints excepted) black; thorax obsoletely impressed, impunctate; elytra

extremely minutely punctured, fulvous, the suture broadly, and the posterior portion black.

Length 2 lines.

Head impunctate, flat, without any elevations ; antennew black, the lower two joints fulvous, the fourth longer

than the preceding two joints together; thorax scarcely broader than long, slightly constricted at the

base, the surface impunctate, with two shallow but large depressions; scutellum fulvous; elytra scarcely

perceptibly punctured in irregular rows, with a distinct flattened margin, fulvous, a sutural stripe,

widening anteriorly, and the posterior portion (the lateral margin excepted) violaceous-black ; legs fulvous ;

the first joint of the posterior tarsi as long as the following three joints together ; claws appendiculate.

90. Malacorhinus cobanensis. (Tab. XLIII. fig. 18, ¢.)

Black, above fulvous ; thorax impunctate; elytra very minutely punctured, with a subtriangular spot at the

base and a transverse one below the middle, black. ,

g. Elytra strongly widened at the middle, the sides with a deep fovea before this, and the lateral margin

turned inwards at.the same place.

Length 2 lines.

Hab. Guatemata, Coban in Vera Paz (Conradt).

Closely allied to several other species, especially to M. plagiatus and M. godmant ;

but differing from the first mentioned in the shape of the elytral spots, and in the

elytral fovea of the male being placed before (instead of below) the middle, and from

M. godmani in the colour and structure of the antenne, which are entirely black and

have the intermediate joints in the male undilated. The anterior elytral spot is of

elongate subtriangular shape, the species differing in this respect from all its allies.

The female is of more parallel shape, and devoid of the elytral fovea.

21. Malacorhinus exclamationis. (Tab. XLIII. fig. 19, ¢.)

Testaceous, the antenne, tibiw, and tarsi black; head and thorax impunctate; elytra extremely minutely

punctured, pale testaceous, the sutural and apical margins, and a narrow longitudinal stripe extending

from the shoulder to the middle of the disc, usually connected with a post-median spot, fuscous or piceous.

¢. Elytra with a deep elongate fovea at the middle of the lateral margin, bounded anteriorly and posteriorly

by a tubercle, the tubercles fulvous in colour.

Length 12 line.

Hab. Mexico, Tapachula in Chiapas (Hége).

This small species, of which several specimens of both sexes were obtained, may be

easily recognized by the pale testaceous colour, and by the !-like elytral markings.

These markings, however, are sometimes more or less interrupted, or, on the contrary,

confluent. The female is devoid of the elytral fovea, but has a slight humeral ridge

instead. |

Black ; the thorax flavous, impunctate; elytra bluish-black, finely rugose and closely punctured.

Length 3 lines.

Hab. Mexico, Amula and Chilpancingo, both in Guerrero (H. H. Smith).

M. rugipennis is so closely allied to M. ceruleipennis, Jac., that it may only be a

local variety of that species ; it differs from it, however, in the duller, more strongly

punctured, rugose elytra. The antenne extend nearly to the apex of the elytra in both

species. Three examples, all males.

PTELEON (p. 603).

2. Pteleon pubescens. |

Bluish-black, finely pubescent above ; thorax very finely and sparingly punctured ; elytra closely punctured

and finely rugose throughout.

dé. Elytra widened at the sides, each with a triangular elevation at the middle near the suture.

9. Elytra parallel, simple.

Length 3 lines. ;

3. Head with a few minute punctures, the frontal tubercles well developed; antenne short, the first joint

robust, the second short, the third nearly twice as long as the preceding one, subtriangular; thorax

about one-half broader than long, rounded at the sides, rather convex, with an obsolete transverse

depression near the base, finely and sparingly punctured and pubescent ; elytra much wider at the base

than the thorax, flattened and widened at the sides, finely rugose, and clothed with greyish pubescence,

the disc with a highly raised subtriangular elevation near the suture, the epipleuree extremely wide.

Hab. Mexico, near the city (Hage, Flohr).

Of this interesting species I have received several examples of both sexes from

M. Flohr, who states that the insect is found upon the flowers of a species of Convol-

vulus. P. pubescens may be at once known from P. semiceruleus by the finely

pubescent upper surface, and by the subtriangular elevation on the disc of the elytra

in the male. The elytra are bluish in this sex, and nearly black in the female. Herr

Hége only obtained one female specimen.

3. Antenne with the ninth joint enormously dilated, concave below, the apical two joints short and pointed.

Length 14 line.

Hab. Guatemata (coll. Jacoby).

Of this species I have received a single male specimen from the Stuttgart Museum.

It may be known from M. fulvipes and the allied forms by the flavous antenne (the

last two joints excepted, which are black) ; and by the ninth joint in the male being

enormously dilated (instead of the eighth, as in M. fulvipes). In this respect M. lav-

pennis agrees with M. guatemalensis, but in that species the antenne are nearly black,

and the dilated joint is pear-shaped (not rounded). It also differs from M. guatema-

lensis in the thorax being much shorter and transverse, and the elytra entirely

impunctate and of a metallic violaceous colour. The four anterior legs are flavous ;

the posterior femora are piceous (the posterior tibie and tarsi are broken off).

5. Metacoryna pretiosa. (Tab. XLIII. fig. 20, ¢.)

Black, the head metallic violaceous; the thorax flavous, impunctate ; elytra violaceous, very finely punctured

anteriorly.

¢. Antenne with the eighth and ninth joints very greatly thickened.

Length 2 lines.

Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith).

A single specimen. MV. pretiosa( ¢ ) agrees in the structure of the antenne with the

corresponding sex of M. fulvipes, but differs from it in the colour of the head, elytra,

and legs. The antenne have their lower joints more or less stained with fulvous; in

the male sex the fifth to the seventh joints are gradually widened, the eighth joint

greatly dilated and pear-shaped, and the ninth smaller. The head and thorax are

impunctate, and the elytra have a small longitudinal depression close to the suture

near the base.

CYPHOTARSIS.—SCELIDOPSIS. . 339

CYPHOTARSIS. (To follow the genus Scelida, p. 609.)

Body elongate, glabrous; eyes entire, small; antennw with the second and third joints subequal, the eighth,

ninth, and tenth thickened (¢); thorax subquadrate, narrowed at the base; elytra depressed, parallel ;

epipleure broad, indistinct at the apex; legs long and slender ; tibie unarmed ; the first joint of the four

anterior tarsi broadly dilated and elongate, that of the posterior pair longer than the following three

joints together ; claws appendiculate; anterior coxal cavities open.

This genus is proposed for the reception of a single species allied to Scelida and

Chthoneis. It differs from Scelida in the short third joint of the antenne, and in the

structure of these organs in the male; and from Chthoneis in the subquadrate thorax,

and the differently formed antenne. ‘The elytral epipleure are also much broader

than in either of these genera, and the anterior tarsi have their first joint more than

usually widened in the male.

¢. Head rather produced, entirely impunctate, the frontal tubercles broad and strongly developed; the palpi

filiform and pointed; antenne extending to the middle of the elytra, the third joint about one-half

longer than the second, both short, the fourth joint twice the length of the third, the following three

joints gradually widened, the eighth strongly thickened, robust and cylindrical, the apical joints

shortened and becoming gradually thinner; thorax scarcely one-half broader than long, rounded at the

sides before the middle, narrowed at the apex, the angles very slightly produced, the surface rather flat,

with a shallow depression at the base, entirely impunctate ; scutellum rather broad ; elytra elongate and

parallel, subdepressed, extremely minutely punctured, the punctuation only visible under a strong lens ;

legs long and slender; the first joint of the four anterior tarsi broadly dilated.

Mr. Flohr has kindly sent me a male specimen of this species; it is probable that

the female has simple antenne and tarsi.

348 PHYTOPHAGA.—SUPPLEMENT.

This species agrees with the type of the genus, UZ. fulvicollis from Guatemala, in

the strongly developed frontal tubercles and the robust and gradually tapering antenne,

in connection with the punctate-striate elytra and closed coxal cavities; the thorax,

however, is much more transverse and the elytral epipleure are broader. The female

has the antenne much thinner, the third and fourth joints being slender and elongate,

and the lateral interstices of the elytra costate. The elytra in both sexes have a slight

metallic zeneous lustre. Numerous specimens of both sexes. .

my name érevicollis is preoccupied by Leconte; I therefore propose to change it as

above.
