INTRODUCTION.

In this Volume twenty-two groups of Rhynchophora, all belonging to the Subfamily

Curculionine, the Sitonina to the Cryptorrhynchina inclusive, are dealt with. The

classification adopted is mainly that of Lacordaire, modified to some extent to conform

with the system followed by Leconte and Horn, who were the first to detect the

real structural differences between the Otiorrhynchine and the Curculionine proper.

The ‘ Munich Catalogue’ gives but little idea of the vast number of Rhynchophora,

especially as regards the group Cryptorrhynchina, inhabiting Tropical America, and it

will already be seen that they are probably more than twice as numerous in species

as the Phytophaga in this region. Gemminger and Harold (1871-6) give, for the

whole world, Rhynchophora [Curculionide, Anthribide, Brenthide, and Scolytide |

11,591 species, and for the Phytophaga [Chrysomelide, Hispide, and Cassidide] 10,196

species. In this Volume alone, one of four or five that will be required, no fewer

than 1365 species are enumerated ; whereas the total number of Central-American

Phytophaga (inclusive of Hispide and Cassidide) as given in this work (1892-4)

is 2619. In Schénherr’s ‘Genera et Species Curculionidum,’ concluded in 1845,

scarcely any species are recorded from Central America proper, 7. ¢. from between

Mexico and the South-American mainland, and it is therefore not surprising that a

very large proportion of the species enumerated are new. A few of those described,

however, will no doubt prove to be synonymous with South-American forms when the

types can be compared. The identification of closely allied obscure species from

description alone, from specimens from such distant localities as Mexico and Brazil

respectively, is obviously so uncertain that it is preferable to describe such forms as

new, notwithstanding the risk of adding to the synonymy. The genera of the group

Cryptorrhynchina still remain in inextricable confusion, and little more has been done

vil INTRODUCTION.

here than to follow Chevrolat, Pascoe, and Faust in placing a certain number of the

more striking forms under separate generic names. The completion of such a task is

beyond the scope of the present work, and it can only be attempted when the whole of

the American Rhynchophorous fauna is studied.

Amongst the various groups enumerated, it may be noted that only one of those

at all numerous in species, the Anthonomina, is about equally well represented in

the United States of North America. The Hyperina, Cleonina (Lizus excepted),

Pissodina, Erirrhina, Tychiina, and Balaninina are mostly Holarctic, the species

becoming fewer in number within the tropics, such well-known genera as Cleonus

and Pissodes not extending south of Mexico. On the other hand, the groups

Cryptorrhynchina, Hylobiina, Cholina, &c., the members of which mostly attack

trees in their various stages of decay, are extremely numerous, both in species and

individuals, throughout the warmer regions of America. The Sitonina have doubtless

been introduced into Mexico from Europe.

The food-plants and habits of scarcely any of the Central-American Curculionine

have been observed, unfortunately, though it may be stated in a general way that a

very large proportion of the specimens belonging to the groups Hylobiina, Anchonina,

Otidocephalina, Erodiscina, Lamosaccina, Cholina, and Cryptorrhynchina obtained

by the present writer were beaten from the withered leaves or branches of fallen

deciduous trees in forest-clearings. One species, however, Anthonomus grandis, the

‘* Mexican Cotton-boll Weevil,” has now become notorious as a destructive insect

wherever cotton is cultivated.

We are indebted to the authorities of the Berlin Museum for the loan of their

Mexican and Central-American Otidovephalina; to Dr. Chr. Aurivillius and Dr. Yngve

Sjostedt, of the Stockholm Museum, for communicating a number of types described

in Schonherr’s work, as well as some others contained in the Chevrolat collection ; .

and to Dr. K. M. Heller, of the Dresden Museum, for the loan of many Cryptorrhynchids

described by Faust. Prof. G. Biolley, of San José, Costa Rica, has from time to time

forwarded various Costa Rican forms, thus helping us to give a better account of the

fauna of that country than we have been able to do with the other families of beetles

already treated. Mr. H. F. Wickham, of Iowa City, too, has again been kind enough

to supply specimens of many North-American species, invaluable for comparison

with Mexican insects.

Of the thirty-five plates issued, all of which have been drawn and lithographed by

Mr. FE. Wilson, of Cambridge, nineteen (Plates X. and XVIII.—XXXV. inclusive) are

coloured and one (Plate XII.) partially coloured. The complete classified list of the

species figured, as given in the other Volumes of Coleoptera already finished, has been

omitted as unnecessary, the supplement to the present Volume being very short.

requires corroboration. Lacordaire includes the genus amongst the ‘‘ Naupactides,

I have seen one of the types of this species, which, as Allard states, is very like the

European 8. puncticollis, Kirby, but differs from it in having the head sharply sulcate

between the eyes, the prothorax a little more rounded at the sides, and the fifth elytral

interstice callose towards the apex.

Group HYPERINA.

Hypérides, Lacordaire ; Phytonomini, Leconte & Horn (part.) ; Hyperini, Bedel, Petri.

This group contains but few representatives in Tropical America, and these mostly

belonging to the genera Isorrhinus and Phelypera. Listronotus, Jekel (a genus

represented in Mexico, and extremely closely allied to Desiantha, Pase., of Australia),

referred to the Hyperina by Leconte and Horn, seems to me to be more nearly related

to the Erirrhina.

Petri, Monogr. Hyperini, pp. 6, 25 (1901).

- This genus, even if Phytonomus is retained as distinct, includes numerous represen

tatives, most of which inhabit the Palearctic region. The single species now added

from the mountains of Western Mexico is a very remarkable form *.

* In the Sallé collection there is a specimen of Phytonomus rumicis (Linn.) labelled as from “ Mexico,” but

further evidence is required before it can be admitted into our list.

P. rumicis (?=diversus, Gyll., and

comptus, Say) has, however, been recorded from North America.

HYPERA.—ISORRHINUS. 3

1. Hypera ocellata, sp. n. (Tab. I. figg. 1, 2; 1a, profile of head; 14, meso-

and metasternal side-pieces.)

Oblong-ovate, black, shining ; thickly clothed above and beneath with small, narrow, grey scales, these becoming

piliform on the head, rostrum, antenne, and legs, and on the terminal ventral segments, the upper surface

also with scattered decumbent hairs; the elytra with eleven conspicuous black spots, each surrounded by

a line of fulvous or ochreous scales—one on the humeral callus, one at the apex, and two on the dise

of each elytron, and three on the suture (the anterior one of these being immediately behind the

scutellum),—and a line of ochreous scales along the outer margin ; the head also with a line of similarly

coloured scales extending round the eyes, except in front. Head densely, very finely punctate, foveate

between the eyes; the latter transverse, somewhat coarsely facetted, and separated by a space about

equalling their own length; rostrum stout, about as long as the prothorax, gradually widening outwards,

densely punctate to near the tip, which is smooth ; joints 1 and 2 of the funiculus subequal in length, the

scape reaching back to the anterior margin of the eye. Prothorax transverse, barely one-half the width

of the elytra, narrowed and slightly constricted in front, the sides parallel from the middle to the base, the

surface densely, very finely punctate. Elytra oblong-oval, truncate at the base, the humeri obliquely

truncated and somewhat swollen, the disc flattened anteriorly ; finely punctate-striate, the interstices almost

flat and minutely, rugulosely punctate. Beneath closely, very finely punctate. Ventral segments 1 and 2

very broadly and feebly depressed down the middle in the ¢.

Length * 94, breadth 44 millim. (¢ 2.)

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

Two specimens. In its essential characters this insect agrees very well with [/ypera,

but the general coloration is very peculiar, the elytra having eleven irregularly shaped

black spots, each surrounded by a ring of ochreous or fulvous scales. The eyes are

somewhat widely separated.

ISORRHINUS.

Isorhinus, Capiomont, Ann. Soc. Ent. Fr. 1867, p. 443 ; Petri, Monogr. Hyperini, p. 5 (1901).

Isorrhinus, Gemminger & Harold, Cat. Col. viii. p. 2389.

A genus including a few Mexican species f, and differing from Phelypera in the very

short rostrum. J. gibbus and J. undatus have the eyes larger and more rounded than

in either of the forms described by Capiomont, J. gidbus also having the prothorax

widened behind, the elytra gibbous towards the base, and the legs elongate. It is

unnecessary, however, to treat either of these insects as generically distinct from

Lsorrhinus.

each of them being now before me, and these are female and male respectively ; the

male is labelled with the locality “Tuspan.” In this insect the eyes are coarsely

facetted and very narrowly separated above. ‘The elytraare irregularly and subequally

tessellated with fuscous and ochreous scales; and the prothorax has a line of ochreous

scales down the middle. ‘The male has the first ventral segment sulcate, and the fifth

slightly depressed down the middle, there being a patch of dark brown scales on

either side of this space at the apex. One of the types of J. chevrolati, from Tuspan,

is figured.

2. Isorrhinus depressus, sp. n. (Tab. I. figg. 8, ¢; 34, profile of head.)

Oblong-ovate, depressed, piceous, the antenns and the tarsi in part ferruginous ; variegated above with rather

coarse, piliform, fuscous and cinereous scales, and with scattered decumbent hairs, the prothorax with a

median line of cinereous scales ; the squamosity of the under surface and legs in great part cinereous.

Rostrum short and stout, closely punctate ; joints 1 and 2 of the funiculus equal in length; eyes large,

somewhat coarsely facetted, almost contiguous above. Prothorax transverse, densely punctate, the sides

parallel from the middle to the base. Elytra more than one-half wider than the prothorax, moderately

long, flattened on the disc to about the middle, subparallel in their basal half, the humeri rounded; seriate-

punctate, the interstices feebly convex, and closely, very minutely punctate. First ventral segment broadly

and deeply, and the fifth shallowly, depressed down the middle, and the latter with a broad patch of blackish

scales at the tip, in the ¢.

Length 5-6, breadth 23-3 millim. (d 2.)

Hab. Mexico, Cuernavaca in Morelos (/ége).

Eleven specimens. Very like I. fuscomaculatus, but less convex, the elytra flattened

on the disc anteriorly and with the sides straighter, the eyes larger and almost

contiguous above. The dark scales predominate on the elytra.

Hab. Mexico (coll. Chevrolat'), Oaxaca (Hoge).

The type of this species, kindly lent by Dr. Aurivillius, is a male, and a female

obtained by Herr Hége at Oaxaca agrees very well with it, except in its much larger

size. Both have the elytra asymmetrically tessellated with patches of fuscous scales,

the rest of their squamosity being ochraceous. ‘There is a line of ashy scales down the

middle of the prothorax. ‘The eyes are rather finely facetted, and separated above by

a space about equalling the length of the first joint of the funiculus. The first ventral

segment is depressed down the middle in the male. Compared with J. depressus the

present species is much smaller and less elongate, the eyes are less approximate above -

and more finely facetted, and the elytra are more irregularly tessellated with fuscous,

the light colour predominating.

ISORRHINUS. 5

4. Isorrhinus gibbus, sp. n. (Tab. I. figg. 5, 5a, ¢ ; 6, 2 ; 6a, last ventral

segment, 2.)

Ovate, robust, black, the antenne in part ferruginous; thickly clothed with narrow intermixed reddish-brown

(or fuscous) and whitish scales, which have a cupreous or violaceous iridescence in certain lights, and

also with scattered decumbent dark hairs, the squamosity of the scutellum black, and that of the under

surface and legs in part whitish, that of the under surface sometimes almost entirely of this colour.

Head closely punctate, faintly foveate between the eyes; the latter large, finely facetted, somewhat

prominent, rounded as viewed from the side, separated above by a space about equalling one-half the

width of the rostrum; rostrum very short and stout, closely punctate, deeply triangularly impressed at

the tip; joints 1 and 2 of the funiculus subequal in length. Prothorax transverse, subconical, the sides

rounded and converging in front and straight behind; the surface densely, minutely punctate, with

slightly larger punctures intermixed. Elytra oval, gibbous towards the base, about one-half wider than

the prothorax, gradually narrowing from a little below the shoulders, which are rounded; rather finely

seriate-punctate, the interstices almost flat and rugulosely punctate, the fifth very little raised posteriorly.

Beneath closely punctate. First and fifth ventral segments broadly depressed along the middle in the ¢,

the fifth foveate at the apex inthe 9. Legs elongate.

Length 9-103, breadth 43-53 millim. (d Q.)

Hab. Mexico, Acapulco, Iguala, Matamoros Izucar, Juquila (Hoge), Mescala in

Guerrero (H. H. Smith).

Sent in plenty from Acapulco. This species differs from the typical Jsorrhiné in

the larger and more rounded eyes (though they are still broader than long), which are

finely facetted and not all approximate above, the posteriorly widened prothorax, the

gibbous elytra, the longer legs, &c. In the form of the eyes it nearly agrees with

I. undatus, except that in the latter they are a little more transverse.

5. Isorrhinus undatus, sp.n. (Tab. I. fig. 7, 3; 74, profile of head.)

Ovate, convex, black, the antennee in part and the tarsal claws ferruginous ; densely clothed with brown or

brownish-grey piliform scales, and with scattered decumbent hairs, the elytra usually with a more or less

distinct, common, angulate, grey or greyish-ochreous fascia a little beyond the middle ; the squamosity of

the under surface and legs cinereous or brownish-cinereous. Rostrum short and stout, closely punctate,

except at the tip, feebly carinate down the middle ; joints 1 and 2 of the funiculus subequal in length ;

eyes large, rather prominent, finely facetted, narrowly separated above in the 2 and almost contiguous

in the ¢. Prothorax transverse, the sides rounded and converging anteriorly and straight behind ; the

surface densely, finely punctate, transversely depressed in front of the basal margin. Elytra more than

one-half wider than the prothorax, subcordiform in the g, somewhat parallel-sided in the 9; seriate-

punctate, the interstices flat and closely, rugulosely punctate. Beneath closely, finely punctate. First

and second ventral segments broadly and shallowly depressed down the middle, and the fifth flattened and

sparsely. squamose along the centre, in the ¢.

Length 6-7}, breadth 34-4 millim. (¢ @.)

Hab. Mexico, Ventanas, Acapulco, Juquila (Hdge).

Sent in numbers from Ventanas, in Western Mexico. Differs from J. fuscomaculatus

in its broader and more robust form, the larger, more prominent, and finely facetted

eyes, the piliform squamosity of the upper surface, &c. The elytra usually have a

common angulated pallid fascia (formed by an oblong patch at the middle of the

suture and a transverse postmedian fascia on the disc of each elytron) beyond the

behind than in J. fuscomaculatus.

PHELYPERA.

Phelypera, Capiomont, Ann. Soc. Ent. Fr. 1867 ; Petri, Monogr. Hyperini, p. 5 (1901).

Eight species were referred to this genus by Capiomont, one of these being a cma

and widely distributed insect within our limits, the genus ranging from Mexico to

Uruguay.

I. Pronotum without transverse impression at the base.

1. Phelypera isthmica, sp. n. (Tab. I. figg. 8, ; 84, profile of head.)

Broad-ovate, pitchy-black, the antenne and tarsi in part ferruginous ; thickly clothed with narrow tawny

scales, the elytra mottled with whitish and blackish scales, the lighter-coloured ones showing a tendency

to form spots on the alternate interstices. Head closely punctate ; the eyes large, coarsely facetted, and

contiguous above; rostrum slightly longer than the prothorax, moderately stout, thickly punctured,

obsoletely carinate down the middle ; joints 1 and 2 of the funiculus subequal in length. Prothorax

transverse, as wide at the middle as at the base, the sides slightly sinuate behind and rounded and

converging in front, the hind angles acute ; the surface densely, finely punctate, without trace of

transverse depression before the base. Elytra comparatively short, broad, nearly twice the width of the

prothorax, the humeri rounded ; rather coarsely seriate-punctate, the interstices convex, and minutely,

rugulosely punctate, the fifth very little raised posteriorly. Beneath closely, finely punctate. First and

second ventral segments slightly depressed along the middle. Legs comparatively short.

Length 7, breadth 4 millim. (¢ .)

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

One specimen, slightly abraded. This insect has the head and rostrum formed as in

PHELYPERA.—HILIPUS. 7

A very variable species as noted by Capiomont. Both light and dark forms (one of

each of which is figured) have been found at Tapachula, Acapulco, and Chacoj. The

males have the rostrum shorter than in the female, and the first ventral segment

broadly depressed in the middle behind.

Group HYLOBIINA.

This group is nearly equivalent to the “ Hylobiides vrais” and the ‘ Molytides ” of

Lacordaire, the “‘ Hylobiini” of Leconte and Horn, and the “Curculionini” of Bedel,

except that Pissodes, Anchonus, and Oncorrhinus are excluded, the two latter belonging

to the “ Anchonina,” which is distinguishable by the globose, smooth, deeply inserted

head. The Hylobiina are chiefly recognizable by the long curved claw at the apex of

each of the tibia, the apex itself being oblique, dilated, and concave, with the corbel

closely ciliate on either edge; and the stout or moderately stout rostrum, with the

anterior opening of the scrobes almost always visible from above. The gula, except

in Telys, is transversely strigose. The strongly retractile legs and the powerful tibial

claws enable these insects to cling very firmly to the foliage and bark of trees.

In most of the genera the femora are acutely spined and the wings fully developed.

Hilipus represents Hylobius* in Tropical America. Anchonomorpha and Rhecas form

a connecting-link with.the “ Anchonina,” the first-mentioned having the first and

second ventral segments connate at the middle, and the latter having the elytra

soldered together. |

HILIPUS.

Heilipus, Germar, Ins. Spec. Nov. p. 399 (1824) ; Lacordaire, Gen. Col. vi. p. 457.

Hilipus, Gemminger & Harold, Cat. Col. viii. p. 2425.

Hilipus, as here restricted, still includes a vast number of species, and in this respect

must far outnumber Otiorrhynchus, one of the most numerously represented genera of the

Rhynchophora. It might be further subdivided, as noted by Lacordaire, by the exclusion

of the forms having the inner apical angle of the tibie mucronate f (our Section II.) ;

but as this would -remove: more than half the species from the genus, and as it is in

some cases a peculiarity of the female only, I do not think it advisable to adopt this

course. The insects here referred to Hilipus have the scrobes formed to receive the

scape only of the antenna; the seventh joint of the funiculus not forming part of

the club; the eyes large and more or less approximating above; the scutellum mode-

rately large; the femora clavate and acutely dentate ; and the tibie armed with a long

claw at the apex, this (in the species of Section I1.) being sometimes ditferently placed

* In the Sallé collection there is a mutilated specimen of Hylobius pales, Herbst (=assimilis, Boh.),

labelled as from “‘ Toxpam, Mexico,” but there must be some mistake about the locality.

+ To avoid confusion the term “‘ mucronate ” is here applied only to the smaller tooth at the inner apical

angle of the tibie, the larger, apical, one being called the “ claw.”

in the two sexes. In Hilipus and the allied genera the tibie are furnished with two

matted, long, spine-like tufts of hair near the inner apical angle, these projecting

forwards on either side of the claw. The males are usually distinguishable by the

shorter and more rugose rostrum, and often by a longitudinal depression on the first

ventral segment, or two tufts of matted piliform scales at its apex, as well as by the

different position of the tibial claw in some cases. Various modifications of structure

are to be found in H. securiger (a peculiarly;formed antennal club in the ¢ ), H. appen-

diculatus (the claw of the posterior tibia replaced by a spoon-shaped process in the ¢ ),

H. strigipectus (a dense brush of long hairs on the first and second joints of the anterior

tarsi in the 3), H. empiricus, H. penicillatus, &c.

The genus is characteristic of the forest-regions of Tropical America, the various

species attacking the branches of fallen trees, by beating which very many forms were

obtained by myself in Guatemala and the State of Panama.

Hab. Mextco2, Playa Vicente, Toxpam (Sai/é), Jalapa, Cordova, and Paso de San

Juan in Vera Cruz (Hoge), Ojo Chico and Jalapilla (fide Chevrolat 1).

Apparently not uncommon in the State of Vera Cruz. Distinguishable from

H. elegans and other allied forms by the broad, sinuous, white vittee not reaching the

apex of the elytra, though sometimes extending along the suture to near the tip.

The head is deeply foveate between the eyes, which are narrowly separated. The

antenne are inserted before the middle of the rostrum, which is longer in the female

than in the male; the first and second joints of the funiculus are subequal in length.

The venter is broadly depressed down the middle in the males, The sculpture of the

prothorax and elytra is variable.

Panama, Bugaba, Volcan de Chiriqui 2000 to 8000 feet, Caldera, David (Champion),

Chiriqui (ex Boucard).—Co.omsiat.

A very variable insect, but always separable from the Mexican H. cruciatus by the

sinuous whitish or pale ochreous vitte extending to the apex of the elytra, and more

or less surrounding the subapical callosities, which are bare at the summit, as is also

the suture. In both species the elytral vittze are sometimes broadly interrupted

beyond the middle, and often show a tendency to become broken up into spots; and

in H. elegans they are sometimes again interrupted (as described by Guérin) before the

apex, so as to leave an isolated apical spot. The fifteen specimens from Cerro Zunil

(fig. 13) have the inner and outer margins of these stripes much less indented, and the

subapical callosities indicated by a large bare spot. Amongst our long series from

Chiriqui, one only (the insect obtained from Boucard) shows the broad depression on the

disc of the prothorax before the base, mentioned by Guérin, and exhibited in the South-

American individuals before me; others, again, from the same district, are much less

elongate. The rostrum is curved and stout. The antenne are inserted before the middle

in both sexes, but nearer the tip in the males than in the females. Length (excluding

rostrum) varying from 9-17 millim.

3. Hilipus albopictus, sp. n. (Tab. I. fig. 14, ¢.)

Very like H. cruciatus, Chevr., but differing as follows:—The white markings much reduced in extent—the

humeral patch on the elytra represented by a narrow stripe extending forwards from the second one,

and forming a continuation of the prothoracic vitta, which is also much narrowed before the middle, the

anteapical patch represented by an angulated transverse fascia ; the rostrum carinate at the base; the

prothorax less rounded at the sides, and therefore somewhat conical in shape, irregularly granulate

(due to the punctures being confluent and the interstices raised), without trace of raised median line; the

elytra closely seriato-granulatc, the punctures of the striw scarcely discernible; the upper surface duller

and thickly clothed with narrow, minute, greyish scales,

Length 16, breadth 63 millim. (d.-)

Hab. Muxtco, Cuernavaca in Morelos (H. H. Smith).

One specimen. This may be an extremely aberrant form of H. cruciatus ; but as we

have nothing intermediate, and the insect inhabits a different district in Mexico, it

is worthy of a name. In Dr. Sharp’s collection there is a single (2?) example

of a very closely allied species, from Colombia, labelled H. mirus, Chevr. (=viator,

Jekel), n. sp.

4. Hilipus fenestratus, sp.n. (Tab. I. fig. 19, ¢ .)

Oblong-oval, moderately shining, black or piceous, the prothorax with a white vitta on each side, narrowing

in front; the elytra each with three large, white, oblong, suboval patches—one at the base, oblique,

directed outward, another, below it, directed inward and downward (these two often connected laterally

and forming a large curved or S-shaped patch), and a third, transverse, sometimes connected with the

opposite one at the suture,—each enclosing numerous bare longitudinal spaces, and sometimes with an

additional white spot before the apex; the legs, rostrum, and under surface with scattered, narrow, white

scales. Head deeply foveate between the eyes, which are narrowly separated ; rostrum comparatively

slender, curved, about one-third longer than the prothorax, coarsely punctured at the sides towards the

base, for the rest almost smooth ; antenne inserted long before the apex of the rostrum, joints 1 and 2 of

the funiculus subequal in length. Prothorax about as long as broad, rounded at the sides before the

middle, and much narrowed in front; the surface coarsely, irregularly punctate, and often with minute

interstitial punctures and indications of a smooth median line anteriorly. Elytra moderately elongate,

one-half wider than the prothorax, conjointly rounded at the apex, the humeri rounded ; seriate-punctate,

the interstices flat and in some specimens transversely wrinkled. First ventral segment broadly depressed

down the middle in the male.

Length 12-154, breadth 43-63 millim. (¢ 9.)

Hab. Guatremaa, San Juan and Purula in Vera Paz (Champion).

Found in plenty in the forest-regions of Alta Vera Paz. This species is closely

allied to H. cruciatus, but has a longer rostrum, with the antenne inserted further

from the tip, the prothoracic vitte narrow, and the elytral markings very differently

arranged, each of the three large patches enclosing numerous, bare, parallel, longitudinal

spaces. A specimen in the British Museum, labelled “ Mexico,” may belong here;

but it has the white elytral patches much reduced in size, and without the distinct

black lines. :

5. Hilipus albovenosus, sp.n. (‘I'ab. I. fig. 16, 2.)

Oblong-ovate, shining, black, the prothorax with a white vitta on each side; the elytra with a double series

of zigzag white lines, which here and there coalesce, so as to enclose three subtriangular spaces on the

disc of each elytron, these spaces in one specimen including a small white spot; eke win ee

margin towards the sides, Head deeply foveate between the eyes, which are narrowly separated ; rostrum

stout, curved, about as long as the prothorax, thickly punctured towards the base, smooth at the tip;

antenng inserted a little before the apex of the rostrum, joint 1 of the funiculus slightly longer than 2.

- Prothorax about as long as broad, much narrowed in front, and slightly sinuate at the sides behind,

sparsely punctate, and with indications of a smooth, raised, median line towards the apex. Elytra one-

half wider than the prothorax, subparallel towards the base, conjointly rounded at the apex, the humeri

rounded ; seriate-punctate, the interstices smooth and flat. Ventral segments 1 and 2 broadly depressed

down the middle in the male.

Length 123-16, breadth 5-6} millim. (¢ 9.)

Hab. Mexico, Orizaba (Sal/lé).

Two specimens, the female much smaller than the male, and also differing from it in

having the white lines on the elytra a little wider and extending down the suture

towards the apex. JH. albovenosus is a close ally of the Mexican H. cruciatus; it may

be nothing more than an extreme form of H. fenestratus, but I have seen nothing

intermediate.

6. Hilipus hieroglyphicus, sp. n. (Tab. I. fig. 17, ¢ .)

Elongate-oval, moderately shining, black, the antennal scape in part and the tips of the tarsi reddish ; the

prothorax with a narrow submarginal vitta, which is continued down the elytra to near the middle, and

has three short branches extending inward and one outward, some very small spots on the elytra inside

this, an oblique fascia at about one-third from the apex, and four more or less coalescent streaks beyond

it, white; the legs, rostrum, and under surface with scattered, narrow, white scales. Head deeply foveate

between the eyes, which are somewhat distant; rostrum stout, curved, not longer than the prothorax,

closely, coarsely punctate, much smoother at the tip; antenne inserted a little before the apex of the

rostrum, joints 1 and 2 of the funiculus subequal in length. Prothorax about as long as broad, narrowed

in front, and sinuate at the sides behind; the surface very sparsely, coarsely, shallowly punctate, with

traces of a smooth, raised, median line in front. Elytra elongate, much wider than the prothorax,

almost parallel to about the middle, conjointly rounded at the apex, the humeri rounded, seriate-punctate,

depressed behind the scutellum, the interstices flat. First ventral segment broadly and shallowly

depressed down the middle. :

Length 144, breadth 53 millim. (? 2.)

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

One specimen. The arrangement of the elytral markings, the elongate anterior

streak of which is somewhat E-shaped, distinguishes this insect from H. sticticopterus

and other species with white submarginal prothoracic vitte and comparatively smooth

upper surface.

7. Hilipus limbatus, sp. n. (Lab. I. figg. 18, ¢; 184, profile of head.)

Oblong-ovate, rather broad, shining, piceous; the prothorax with a broad vitta on each side and the elytra with

a still broader, strongly sinuous one on the outer part of the disc (formed by a coalescent curved stripe

and a large apical patch), the latter nearly reaching the suture towards the apex and enclosing a rounded

bare space on the subapical callosities, brownish-ochreous, edged on either side with white; the rest of

the upper surface clothed with minute ochreous scales ; the under surface and legs with scattered, narrow,

whitish scales, the propleura with a line of larger whitish scales before the anterior cox. Head foveate

between the eyes, which are narrowly separated ; rostrum moderately stout, feebly curved, nearly twice

as long as the prothorax, punctured laterally on the basal half, for the rest almost smooth; antennz

inserted at about the middle of the rostrum, joint 1 of the funiculus nearly one-half longer than 2.

Prothorax broader than long, rounded at the sides, narrowed in front, depressed on the disc at the base ;

coarsely, confluently punctate, with a smooth, raised, median line. Elytra one-half wider than the

prothorax, subparallel in their basal half, depressed behind the scutellum, conjointly rounded at the apex,

the humeri rounded; deeply seriate-punctate, the interstices flat and transversely wrinkled. First ventral

segment depressed in the middle.

Length 10, breadth 43 millim. (¢.)

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

One specimen. Very like some of the smaller and less elongate forms of the variable

H. elegans; but with a longer, more slender, and less curved rostrum, the antenne

inserted at about the middle of the latter and with a more elongate basal joint to the

funiculus, the prothorax more transverse, &c. The markings of the upper surface are

brownish, bordered on their edge with white, and very like those of some of the

Guatemalan specimens of H. elegans.

8. Hilipus rectirostris, sp. n. (Tab. I. figg. 19, 2; 19a, profile of head.)

Oblong-ovate, comparatively broad and short, shining, piceous, the femora in part and the rostrum more

or less rufescent ; the prothorax with a broad whitish vitta on each side; the elytra with a very broad

curved stripe on the outer part of the disc, extending from the base to about the middle, and a large

apical patch, the two connected in one specimen, and the latter reaching the suture before the apex and

enclosing a small bare spot on the subapical callosities, whitish or pale ochreous; the rest of the surface

and the legs clothed with narrow ochreous scales. Head deeply foveate between the eyes, which are

narrowly separated ; rostrum a little longer than the prothorax, stout, almost straight, thickly punctured,

except towards the tip, obsoletely carinate at the base; antenne inserted far before the middle of the

rostrum, joint 1 of the funiculus longer than 2. Prothorax broader than long, the sides much rounded

and converging anteriorly; coarsely, confluently punctate, and with a smooth median carina. Elytra

about one-half wider than the prothorax, comparatively short, subparallel towards the base, depressed

behind the scutellum, conjointly rounded at the apex, the humeri rounded ; coarsely seriate-punctate, the

interstices transversely wrinkled and towards the base granulate.

Length 7-8, breadth 34-43 millim. (9.)

Hab. Mexico (Sallé); Guatemana, Cerro Zunil (Champion).

Two specimens, the Guatemalan one figured differing from the other in having the

elytral markings longitudinally confluent. Differs from H. elegans and H. limbatus

in the almost straight rostrum, which is also much shorter and stouter than in the

jast-mentioned insect, and the relatively shorter elytra. There are two nearly

allied South-American forms in the British Museum, labelled H. draco (Fabr.) and

H. parvulus, Boh., respectively.

9. Hilipus ornatus, sp. n. (Tab. I. fig. 20, ¢.)

Narrow, subcylindrical, shining ; rufo-piceous, the prothorax with a moderately broad whitish vitta on each

side, narrowing in front; the elytra with a broad, irregular, sinuous stripe at the sides extending from the

base to about the middle, from which a short ramus runs inward posteriorly to the third row of punctures,

and a large transverse oval patch before the apex, nearly reaching the suture and enclosing a bare smooth

space at the tip of the anteapical callus, also whitish, the edges of both markings more or less excised ;

the upper surface elsewhere clothed with a fine ochreous pubescence; the under surface and legs with

- HILIPUS. 13

narrow whitish scales. Head deeply foveate and punctured between the eyes, which are somewhat

distant ; rostrum stout, curved, longer than the prothorax, somewhat coarsely punctured, except towards

the tip, obsoletely carinate at the base, and with a short sulcus between the points of insertion of the

antenne ; the latter inserted at about one-third from the apex of the rostrum, and with joints 1 and 2 of

the funiculus subequal in length. Prothorax about as long as broad, somewhat rounded at the sides,

irregularly punctate, the punctures becoming coarser and transversely confluent towards the base, the

disc with a smooth central line, the flanks obsoletely granulate. Elytra elongate, subparallel in their

basal half, conjointly rounded at the apex, a little more than one-fourth wider than the prothorax,

flattened towards the suture, the humeri obliquely rounded, obtuse in front; seriate-punctate,

the interstices transversely wrinkled. First ventral segment somewhat deeply depressed down the

middle.

Length 11, breadth 33 millim. ( 92.)

Hab. Panama, Volcan de Chiriqui (Champion).

One specimen. This species is coloured almost exactly like some of the small

varieties of H. elegans occurring in the same district; but may be readily distinguish-

able therefrom by its narrow subcylindrical shape, and the relatively much narrower

elytra. The whitish markings are slightly tinged with ochreous, and those on the

elytra more or less excised at the edges.

10. Hilipus furcatus, sp.n. (Tab. I. fig. 21, ¢.)

Narrow, subcylindrical, shining, black; the prothorax with a rather broad whitish vitta on each side, which

is continued down the outer part of the elytra to far beyond the middle, and there connected with a

curved oblique fascia extending from near the outer margin to the suture before the apex, and has two

rami extending inwards to the second or third row of punctures and another running outwards to near

the margin ; the legs, rostrum, and under surface with scattered, narrow, white scales. Head coarsely

punctured and foveate between the eyes, which are somewhat distant; rostrum stout, curved, about as

long as the prothorax, coarsely punctured at the sides towards the base, for the rest almost smooth ;

antenns inserted some distance before the apex of the rostrum, joints 1 and 2 of the funiculus subequal

in length. Prothorax convex, about as long as broad, rounded at the sides, narrowed in front, almost

parallel behind ; the surface with widely scattered punctures, Elytra elongate, widest a little beyond the

middle and here barely one-third wider than the prothorax, conjointly rounded at the apex, the humeri

rounded; rather coarsely seriate-punctate, the interstices transversely wrinkled.

Length 104, breadth 3} millim. (2.)

Hab. Muxico, Jalapa (Hoge).

One specimen. This insect somewhat resembles H. hieroglyphicus in general colora-

tion; but is of more cylindrical shape, with the thorax more rounded at the sides and

the elytra relatively narrower.

11. Hilipus cylindricus, sp. n. (Tab. I. fig. 22, 9.)

Narrow, elongate, cylindrical, shining, rufo-piceous, blackish below the shoulders and at the apex of the

elytra, clothed above with very minute, piliform, ochreous scales, which tend to become more concentrated

towards the sides of the prothorax ; the prothorax with a small whitish spot on either side at the base ;

the elytra with numerous more or less coalescent spots at and below the humeri, forming an irregular,

oblong, humeral patch and an oblique one behind it, and others before the apex, the latter forming a

common transverse fascia, ochreous; the under surface and legs with scattered, narrow, whitish scales,

Head foveate and thickly punctured between the eyes, which are somewhat distant; rostrum stout,

curved, longer than the prothorax, thickly punctured towards the base and smooth at the tip, and with a

short sulcus between the points of insertion of the antenne ; the latter inserted at about one-third from

the apex of the rostrum, and with joints 1 and 2 of the funiculus equal in length. Prothorax rather

longer than broad, the sides slightly rounded and converging a little towards the apex; the surface

somewhat coarsely, confluently punctate, with a smooth, raised, median line in front, the interspaces here

and there asperate. Elytra elongate, subparallel to beyond the middle, conjointly rounded at the apex,

rather more than one-third wider than the prothorax, the humeri obliquely rounded, obtuse in front;

seriate-punctate, the interstices transversely wrinkled. First and second ventral segments feebly depressed

in the middle behind. .

Length 10, breadth 3 millim. ( 9.)

Hab. Nicaracva, Chontales (Belt).

One specimen. Not unlike H. ornatus, but still narrower and more cylindrical, the

prothorax without marginal vitte, the elytral markings reduced in extent and formed

by coalescent spots.

12. Hilipus collectus. (Tab. I. figg. 23, 3; 234, profile of head.)

Hilipus collectus, Pasc. Trans. Ent. Soc. Lond. 1881, p. 68°.

Hab. Nicaracua, Chontales 1 (Belt, Janson).

We have received five specimens of this species. It is chiefly recognizable by the

disposition of the pale ochreous markings on the upper surface, these consisting of a

small spot or oblong streak on either side of the base of the prothorax and numerous

spots on the elytra, the latter more or less concentrated in places, and showing

a tendency to form a patch at the shoulders, an oblique fascia below this, and a

transverse, common, anteapical band. The second joint of the funiculus is a little

shorter than the first.

13. Hilipus trifasciatus, sp.n. (Tab. I. figg. 24, ¢; 25, 3, var. f.)

Oblong-ovate, moderately shining, black, the head, the prothorax (except at the base and apex), the incras-

sate portion of the femora, the apical joint of the tarsi, and the metasternum, in part, often rufous;

the upper surface in fresh specimens thickly clothed with a very short fulvous or greyish pubescence ;

the prothorax sometimes with an interrupted ochreous vitta on each side, usually reduced to a single

spot at the base, and a similarly coloured streak beneath in front of the anterior coxe; the elytra with

numerous patches of ochreous or whitish scales, these concentrated in places and forming three interrupted

transverse fascie ; the underside and legs clothed with scattered, narrow, white scales. Head deeply

foveate between the narrowly separated eyes; rostrum stout, curved, as long as or a little longer than

the prothorax, irregularly and rugosely punctured at the sides, and sometimes carinate in the middle

towards the base, for the rest almost smooth; antenne inserted far before the middle of the rostrum,

joints 1 and 2 of the funiculus subequal in length. Prothorax about as long as broad, moderately convex,

rounded at the sides, much narrowed in front and slightly so towards the base; the surface rather

coarsely, irregularly punctate, usually with indications of a smooth central line, the interspaces sometimes

more or less granulate. Scutellum sometimes with a few white scales. Elytra about one-half wider than

and fully three times as long as the prothorax, subparallel in their basal half, conjointly rounded at the

apex, the humeri rounded ; seriate-punctate, the interstices flat, in some specimens faintly transversely

wrinkled or obsoletely granulate. Venter smooth, in the ¢ broadly depressed down the middle of the

first two segments.

Var. a. Duller, the spots on the elytra less numerous; the prothorax sparsely punctured or with a few widely

scattered granules.

HILIPUS. 15

Var. /3. Prothorax very sparsely finely punctate, and with a short ochreous vitta on each side at the base ;

the ochreous markings on the elytra in the form of short longitudinal streaks. (Fig. 25.)

Length 10-18, breadth 41-7} millim. (¢ @.)

Hab. Nicaraaua, Chontales (Belt, Janson, Richardson).

Sent in plenty from Chontales, the form « indiscriminately with the type, by all

three collectors, a few examples only showing a tendency to granulation on the

prothorax and elytra. The elytral markings resemble those of H. collectus, from which

the insect differs in its comparatively broader form, smoother rostrum, more distinctly

punctured prothorax, &c. The var. f (fig. 25) is represented by a single specimen.

14. Hilipus belti, sp. n. (Tab. I. fig. 26, 2.)

Oblong-ovate, shining, black, the prothorax (except at the base and apex), the incrassate portion of the femora

and the side-pieces of the metasternum rufous; the prothorax with a small patch of white scales on each

side in front; the elytra with numerous, irregular, transverse or oblique patches of white scales, tending

to form fascize; the underside and legs with scattered, narrow, white scales. Head deeply foveate between

the eyes, which are somewhat widely separated; rostrum very stout, curved, sparsely punctured towards

the base, smoother at the tip, the antennal grooves rapidly descending; antenne as in 4. trifasciatus.

Prothorax conical, distinctly longer than broad, sparsely punctate. Elytra more than three times the

length and (at the widest part) nearly twice the width of the prothorax, conjointly rounded at the apex,

the humeri rounded ; seriate-punctate, the interstices faintly transversely wrinkled.

Length 20, breadth 74 millim. (2.)

Hab. Nicaragua, Chontales (Belt).

‘The above description is taken from a single female specimen, which is separable at

a glance from the same sex of H. trifasciatus by the longer, conical prothorax, the

more widely separated eyes, and the stouter and smoother rostrum. A male from

Chontales (Janson) may belong here, as it has a similar head and rostrum; but

the general shape of the prothorax is very like that of H. trifasciatus, except that

there is a broad deep depression on each side of the disc before the middle. The

prothorax, however, appears to be abnormally formed in this insect, which cannot,

therefore, be certainly located till further material has been obtained. No such sexual

difference in the form of the prothorax is known to me amongst any of the other

species of the genus.

15. Hilipus albonotatus, sp. n. (Tab. II. fig. 1, ¢.)

Elongate-oval, moderately shining, piceous or rufo-piceous ; the prothorax with a broad vitta on each side,

narrowing in front, and the elytra with a small spot on the fifth interstice at the base, a short, oblique,

angulated fascia towards the sides before the middle, and another before the apex, the latter nearly

reaching the suture, white; the legs, rostrum, and under surface with scattered, narrow, whitish scales.

Head deeply foveate between the eyes, which are narrowly separated ; rostrum distinctly longer than the

prothorax, stout, curved, coarsely, sparsely punctate, except towards the tip, which is much smoother, the

antennal grooves narrowly separated behind; antenne inserted a little before the apex of the rostrum,

joints 1 and 2 of the funiculus subequal in length. Prothorax slightly longer than broad, narrowing

-4n front; the surface sparsely punctate, with a narrow, ill-defined, smooth space down the middle.

Elytra elongate, one-half wider than the prothorax, widest at the base, conjointly rounded at the apex,

the sides almost straight to beyond the middle, the humeri rounded; flattened on the disc, depressed

behind the scutellum, rather finely seriate-punctate, the interstices flat. Venter depressed along the

middle towards the base.

Length 133-15, breadth 43-5 millim. (¢ Q.)

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

Six specimens, apparently including both sexes, some of them having a longer

ventral depression than others. Distinguishable from all the other Central-American

forms by the disposition of the white markings on the elytra, these showing no tendency

to vary. The antennal grooves are only separated by a very narrow ridge at the base

of the rostrum beneath.

16. Hilipus albomaculatus, sp. n. (Tab. II. fig. 2, 2.)

Oblong-oval, moderately shining, piceous ; the prothorax with a broad vitta on each side, narrowing in front,

this being continued on the elytra to near the middle in the form of a broad, curved, submarginal band,

and the elytra also with a broad auteapical fascia, not quite reaching the suture, white; the under surface

and legs with scattered, narrow, white scales. Head deeply foveate between the narrowly separated eyes ;

rostrum distinctly longer than the prothorax, curved, stout, coarsely, closely punctate and obsoletely

carinate towards the base, much smoother at the tip, the antennal grooves narrowly separated behind 5

joints 1 and 2 of the funiculus subequal in length. Prothorax about as long as broad, narrowed in front

and slightly so behind, sparsely punctate, with a narrow smooth space down the middle towards the apex.

Elytra moderately elongate, widest a little below the base, conjointly rounded at the apex, the humeri

broadly rounded and not at all prominent ; rather finely seriate-punctate, the interstices flat, the scutellar

region depressed.

Length 14, breadth 34 millim. (9.)

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

One specimen. Very like H. albonotatus, but more robust, with shorter and stouter

legs, the elytra broader and widest a little below the base, the prothoracic vitte

continued on to the basal portion of the wing-cases in the form of a broad, curved, sub-

marginal stripe, which extends inwards to the third row of punctures, and (like the

subapical fascia) is not excised on either edge.

17. Hilipus stictopterus, sp. n. (Tab. II. figg. 3, ¢ ; 4, 3, var.)

Elongate-oval, dull or slightly shining, black or piceous, the head and rostrum usually rufescent; the pro-

thorax with a broad vitta on each side above and a narrow line in front of the anterior coxe whitish or

pale ochreous; the elytra with numerous, more or less coalescent, similarly-coloured spots towards

the sides, extending from the base to the apex; the under surface, legs, and rostrum with scattered,

narrow, whitish scales. Head very deeply foveate between the eyes, which are narrowly separated ;

rostrum about as long as the prothorax, stout, curved, thickly and rather coarsely punctured, except at

the tip, which is much smoother ; antenne inserted a little before the apex of the rostrum, joint 1 of the

funiculus slightly longer than 2. Prothorax as long as broad, narrowing from the middle forwards ;

the surface closely punctate in some examples, almost smooth in others, and with indications of a

smooth, raised, central line anteriorly. Elytra elongate, one-half wider than the prothorax, very

gradually narrowing from the base, conjointly rounded at the apex, the humeri rounded; flattened on the

disc, depressed behind the scutellum, seriate-punctate, the interstices broad and faintly transversely

wrinkled. Ventral segments 1 and 2 with a few scattered punctures, and in the ¢ broadly depressed

along the middle.

HILIPUS. 1?

Var. The elytral spots coalescent and forming a sinuous submarginal vitta (fig. 4).

Length 123-16, breadth 34-53 millim. (¢ 9.)

Hab. Panama, Volcan de Chiriqui (Champion).

Found in plenty by myself on the slopes of the Volcan de Chiriqui, the form with a

few shallow widely-scattered punctures only on the disc of the prothorax predominating.

The variety, of which a single specimen only was captured, is very like the Costa-

Rican Z. bivittatus, but has the prothorax more narrowed in front and the coalescent

spots on the sides of the elytra forming sinuous vitte. The present species is nearly

allied to H. collectus, from which it may be known by the complete prothoracic vitte,

and by the elytral spots being concentrated along the outer part of the disc, showing

no tendency to form oblique fasciz. The specimens with a closely punctured prothorax

are more shining than the others.

18. Hilipus bivittatus, sp.n. (Tab. II. fig. 5, 2.)

Elongate, subcylindrical, moderately shining ; the prothorax and elytra each with a broad submarginal pale

ochreous vitta, the two vitte not confluent at the apex, the elytra in one specimen (2?) also with two

detached similarly-coloured spots on the third interstice; the under surface with scattered ochreous

scales, which are concentrated into small patches towards the sides; the legs and rostrum with narrow

whitish scales. Head deeply foveate between the eyes, which are rather narrowly separated ; rostrum

stout, curved, as long as the prothorax, rugosely punctured towards the base, almost smooth at the tip;

antennee inserted far before the middle of the rostrum, joint 1 of the funiculus slightly longer than 2.

Prothorax longer than broad, very little narrowed in front, the sides more parallel in the ?; the surface

coarsely punctured (except upon the space occupied by the vittee), and with indications of a raised central

line, the flanks rugosely punctured and in one specimen (2) granulate. Elytra elongate, subparallel to

beyond the middle, at least one-half wider than the prothorax, conjointly rounded at the apex, the humeri

rounded ; seriate-punctate, the interstices broad and more or less wrinkled transversely. Ventral segments

1 and 2 with a few scattered punctures, and in the ¢ broadly depressed down-the middle.

Length, g 13, 2 19; breadth, ¢ 4, Q 6 millim.

Hab. Costa Rica (Van Patten), Caché (Rogers).

One pair. The female has the prothorax longer and less narrowed anteriorly than in

the male, and also much more coarsely and closely punctured. This species is allied to

H. peplus, Guér., and other South-American forms, from which it may be distinguished

by its narrower and more parallel shape, the straighter elytral vitte, &c. From

H. norrisii, Guér. ((=H. chevrolatii and H. bohemant, Guér.), from Colombia, it differs

in the regularly seriate-punctate disc of the elytra, and the absence of a line of yellow

scales near the suture, &c. .

19. Hilipus areolatus, sp. n. (Tab. II. fig. 6, ¢.)

Elongate-ovate, shining, black or pitchy-black, the rostrum and tarsi sometimes reddish ; the prothorax with

two lines of ochreous scales on each side, these becoming coalescent at the base and apex and enclosing

an elongate-triangular space ; the elytra with two zigzag lines of similarly-coloured scales on the disc and

another down the sutural stria, which are here and there connected so as to enclose large triangular

spaces, the lines themselves becoming more tortuous at the apex; the rest of the upper surface, as well

as the body beneath and the legs, clothed with widely-scattered; narrow, white scales, the pro-, meso-, and

metapleura with a line of larger ochreous scales. Head almost impunctate, deeply foveate between the

eyes, which are narrowly separated ; rostrum curved, considerably longer than the prothorax, moderately

stout, with a few scattered punctures only at the sides towards the base ; antenne inserted far before the

middle of the rostrum, joint 1 of the funiculus longer than 2. Prothorax about as long as broad, rounded

at the sides anteriorly, coarsely, confluently punctate, and sometimes with a narrow smooth space or

raised line down the middle. Elytra rather convex, about one-half wider than the prothorax, sub-

parallel at the base, conjointly rounded at the apex, the humeri rounded ; seriate-punctate, the interstices

smooth and flat. Ventral seements 1 and 2 deeply depressed down the middle in the male.

Length 11-144, breadth 4-5} millim. (¢ Q.)

Hab. Costa Rica (Van Patten); Panama, Volean de Chiriqui 4000 feet (Cham-

pion).

Six examples. Easily distinguishable from all the other Central-American species

of the genus by the network of narrow lines of ochreous scales on the upper surface,

those on the prothorax enclosing a triangular space on each side, and those on the

elytra here and there connected on the disc, enclosing large triangular spaces, except

towards the apex, where the lines become tortuous. The South-American H. mysticus,

Pasc., is an allied form, but differs from the present species in having the upper surface

smoother, the femora partly red, and the sinuous lines on the elytra differently arranged,

not forming a zigzag line on the disc of each.

20. Hilipus clathratus, sp.n. (Tab. IIL. figg. 7, ¢; 74, profile of head.)

Oblong-ovate, shining, pitchy-black, the rostrum and the legs and antenne in part rufescent; the prothorax

with a rather narrow ochreous vitta on each side, which curves inwards at the apex; the elytra with

various sharply-defined ochreous lines—two of these enclosing a very large, common, rhomboidal space on

the dise before the middle, the anterior line sending off a branch in front to meet the prothoracic vitta,

the posterior line followed by two transverse ones (one oblique and the other curved),—and the outer

and apical margins, a curved streak behind the subapical callus, and the punctures of the striew also,

more or less clothed with similarly-coloured scales ; the rest of the upper surface with widely-scattered,

narrow, ochreous, and the under surface and legs with whitish, scales, the pleura and each of the ventral

segments 1-4 at the sides in front with lines of larger ochreous scales. Head deeply foveate between

the eyes, which are rather narrowly separated; rostrum very nearly twice as long as the prothorax,

rather slender, feebly curved, smooth, with a few scattered punctures only at the sides towards the base ;

antenne inserted at about the middle of the rostrum, joint 1 of the funiculus nearly twice as long as 2.

Prothorax broader than long, rounded at the sides and much narrowed in front, very coarsely confluently

punctate, and with a smooth, raised, median line anteriorly. Hlytra one-half wider than the prothorax,

parallel at the base and narrowing thence to the tip, conjointly rounded at the apex, the humeri rounded;

coarsely seriate-punctate, the interstices smooth and flat. Ventral segments 1 and 2 broadly and

shallowly depressed down the middle.

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

One specimen. A very distinct species, with ochreous lines on the elytra, as

in H. areolatus (though very differently arranged), and a very long feebly curved

rostrum.

Heilipus lauri, Boh. in Schénh. Gen. Cure. viii. 2, p. 448.

Hab. Mexico, Capulalpam (Saldé).

Two specimens of this species are contained in the Sallé collection. The type is

stated to have passed its metamorphosis in a fruit of Persea (Laurus) drymifolia.

H., lauri is easily recognizable by its very long rostrum, conical prothorax, and some-

what cordiform elytra, the latter with two short, narrow, transverse, pale ochreous

fascie.

22. Hilipus longirostris, sp.n. (Tab. IT. figg. 9, 2; 94, profile of head.)

Oblong-ovate, shining, piceous, the rostrum, antenna, and legs reddish; the prothorax with an ill-defined

oblique vitta on each side of the disc, which becomes very narrow in front and is formed of intermixed

white and fulvous scales, the disc with scattered ochreous pubescence; the elytra with various oblong or

rounded fulvous spots, which form an irregular curved series on the outer part of the disc below the base,

a common, sinuous, transverse, subapical fascia, and a rounded apical patch, these markings interspersed

with very small pure white spots, the rest of the surface with minute, scattered, ochreous scales; the

under surface, legs, and rostrum with scattered, narrow, white scales. Head deeply foveate between the

eyes, which are narrowly separated; rostrum slender, about three times as long as the prothorax,

strongly curved, thickly punctured towards the base; antenne inserted slightly before the middle of the

rostrum, joint 1 of the funiculus one-half longer than 2. Prothorax a little broader than long, deeply

bisinuate at the base, narrowed in front, the sides rounded anteriorly and almost straight behind ;

coarsely confluently punctate, and with a narrow smooth space down the middle. LElytra about one-half

wider than the prothorax, narrowing from a little below the base, flattened on the disc, conjointly

rounded at the apex, the humeri rounded; coarsely seriate-punctate, the discoidal interstices strongly

transversely rugose, the punctures of the striz thus appearing to be transversely confluent. Metasternum

and venter almost smooth.

Length 12, breadth 42 millim. (2.)

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

One example. This species is extremely like H. mixtus and H. atomarius, both of

which inhabit the same district, but it is readily separable therefrom by the exceedingly

long, curved, and slender rostrum.

23. Hilipus atomarius, sp.n. (Tab. II. figg. 10, 2; 10a, profile of head.)

Oblong-ovate, shining, piceous or rufo-piceous, the rostrum rufescent at the apex in one specimen; the

prothorax with a narrow white vitta on each side, upon which a few ochreous scales are visible, and

scattered whitish pubescence ; the elytra with various oblong or rounded fulvous spots, which form a

curved longitudinal series on the outer part of. the disc below the base, a common, sinuous, transverse,

subapical fascia, and a small apical patch, these markings interspersed with very small white spots, which

become larger at the base, the rest of the surface with scattered ochreous or white scales; the under

surface, legs, and rostrum with scattered, narrow, white scales. Head very deeply foveate between’ the

eyes, which are narrowly separated; rostrum stout, moderately curved, nearly twice as long as

about one-third from the apex of the rostrum in the ¢, further back in the 2, joint 1 of the funiculus

slightly longer than 2. Prothorax a little longer than broad, narrowed in front, rounded at the sides

anteriorly; coarsely, confluently punctate, and with a smooth, raised, median line. Elytra one-half wider

than the prothorax, widest a little below the base and narrowing thence to the apex, flattened on the

interstices transversely rugose, the punctures of the striw thus appearing to be transversely contluent,

Ventral segment 1 broadly depressed along the middle in the male, and narrowly 80 in the female.

Length 11-14, breadth 43-5? millim. (d 2.)

Hab. Paxama, Bugaba, Volcan de Chiriqui (Champion).

One pair. Very like H. longirostris, but with a much stouter and shorter rostrum,

even in the female; the prothoracic vitte more distinctly defined; the markings of

the elytra very similar, except that there are larger patches of white scales at the base

in the present insect.

24. Hilipus mixtus, sp. n. (Tab. Il. figg. 11, ¢; 11, profile of head.)

Oblong-ovate, shining, piceous, the tarsi and the tip of the rostrum rufescent; the prothorax with an

ill-defined oblique vitta on each side formed of intermixed white and fulvous scales, the disc with

scattered ochreous pubescence; the elytra with various oblong or rounded fulvous spots, which tend to

form an oblique fascia below the shoulders, a short transverse fascia before the middle (the two together

forming an irregular curved band), a complete subapical arcuate fascia, and an apical patch, the rest of

the surface with very small, scattered, whitish spots and narrow, minute, ochreous scales; the under

surface, rostrum, and legs with scattered, narrow, white scales. Head very deeply foveate between the

eyes, which are narrowly separated ; rostrum stout, curved, about one-third longer than the prothorax,

thickly punctured towards the base, almost smooth at the tip; antenne inserted towards the apex of the

rostrum, joints 1 and 2 of the funiculus subequal in length. Prothorax a little longer than broad, much

narrowed in front, rounded at the sides before the middle; coarsely confluently punctate, and with

indications of a smooth, raised, median line. Elytra convex, one-half wider than the prothorax, widest

about the middle, and slightly narrowing thence to the base, conjointly rounded at the apex, the humeri

rounded ; seriate-punctate, the interstices transversely rugose. Ventral segments 1 and 2 very broadly

depressed down the middle.

Length 14, breadth 54 millim. (¢-)

Hab. Panama, Volcan de Chiriqui 5000 feet (Champion).

One specimen. Very like H. atomarius and H. longirostris, but with a shorter

rostrum, a longer prothorax, and more convex elytra, the latter widest at the middle

and narrowing forwards. The differences are too great to admit of its being treated as

the male of H. longirostris, the female only of which is known. ‘The present species

is also a close ally of the South-American /H. apiatus, Oliv., which is a larger insect

and has the elytral spots irregularly scattered over the whole surface, and nowhere

ageregated so as to form fasciz.

25. Hilipus guttiger, sp.n. (Tab. II. figg. 12, ¢; 124, profile of head.)

Oblong-ovate, shining, piceous or rufo-piceous, the prothorax (except at the base), head, rostrum, and legs

sometimes rufous; the prothorax with an ill-defined, narrow, oblique, whitish vitta on each side and for

the rest clothed with scattered ochreous pubescence ; the elytra with a broad curved stripe on the outer

part of the disc extending from the base to about the middle (in one specimen divided into two), and a

very large rounded patch immediately before the apex, the latter extending to the suture, but not to the

apical angle, and enclosing a bare spot on the subapical callus, ochreous or pale ochreous, the rest of

the surface with scattered, minute, whitish or ochreous scales, which fill up the depressions of the surface

and form small spots; the under surface, legs, and rostrum with scattered, narrow, whitish scales. Head

foveate between the eyes, which are narrowly separated; rostrum about three-fourths longer than the .

prothorax, feebly curved, moderately stout, thickly punctured towards the base ; antenne inserted far

before the middle of the rostrum, joint 1 of the funiculus nearly twice as long as 2. Prothorax broader

than long, narrowed in front, and rounded at the sides before the middle; coarsely confluently punctate,

and with an incomplete, smooth, raised, median line. Elytra comparatively short, one-half wider than

the prothorax, subparallel towards the base, conjointly rounded at the apex, the humeri rounded ;

coarsely seriate-punctate, the interstices strongly transversely wrinkled.

Length 8-94, breadth 4-44 millim. (¢.)

Hab. Mexico, Toxpam (Sallé); Guaremata, Zapote (Champion); Panama, Volcan.

de Chiriqui (Champion).

One specimen from each locality. This species somewhat resembles Z. rectirostris,

H. limbatus, H. elegans, &c.; but has narrow ill-defined prothoracic vittee and trans-

versely rugose elytra, the depressions of the surface between the markings being

clothed with minute ochreous or whitish scales, so as to form numerous, small,

coalescent spots.

26. Hilipus 12-guttatus, sp. n. (Tab. II. figg. 13, ¢; 134, profile of head.).

Elongate-ovate, shining, the rostrum and the prothorax and femora in great part rufous; the elytra each

with six fulvous spots—one at the base, two in an oblique line on the outer part of the disc before the

middle, and three before the apex, the outer anterior one of these in the form of a short curved fascia,—

the foves filled with pale ochreous scales; the depressions on the prothorax, as well as the under surface

and legs, clothed with whitish scales. Head deeply foveate between the eyes, which are depressed and

narrowly separated ; rostrum very stout, curved, about one-half longer than the prothorax, very sparsely

punctured at the base and smooth beyond; antenne inserted before the middle of the rostrum, joint 1

of the funiculus one-half longer than 2. Prothorax convex, broader than long, narrowed in front,

the sides rounded anteriorly; coarsely confluently punctate, the interspaces transversely rugose, the

disc with a smooth space down the middle. Elytra one-half wider than the prothorax, subparallel in

their basal half, conjointly rounded at the apex, the humeri rounded ; irregularly seriato-foveate, the

fovere here and there transversely confluent, the interstices smooth and shining. Ventral segments

1 and 2 broadly depressed down the middle.

Length 11, breadth 43 millim. (¢.)

Hab. Nicaraeva, Chontales (Belt).

One specimen. An isolated form, distinguishable by its convex rugose prothorax

and foveolate elytra, the latter each with six fulvous spots and the fovee filled with

pale ochreous scales. Not unlike H. paradorus, Pasc., from Cayenne, but more

elongate and with a much shorter rostrum, the eyes not rounded, the femoral tooth

patch at each of the hind angles, the elytra with various pale ochreous spots, these

tending to form a straight, transverse, median, and a curved subapical, fascia. ‘The male

has the first ventral segment broadly depressed down the middle. The head is deeply

foveate between the eyes. The scrobes are directed downwards, and are separated

only by an acute ridge at the base of the rostrum beneath. H. wndabundus, Boh.,

from Brazil, is very like the present species.

28. Hilipus sexmaculatus, sp.n. (Tab. II. figg. 1, 3; 15a, profile of head.)

Elongate-ovate, piceous, the prothorax with a rather narrow whitish vitta on each side; the elytra with a

small transverse spot at the shoulders, a short, oblique, angulated fascia at the sides before the middle,

and an irregular transverse spot or fascia on the disc before the apex, also white; the depressions on the

rest of the upper surface thickly clothed with minute ochreous scales, amongst which on the prothorax

some much longer ones are visible; the under surface, head, rostrum, and legs with scattered, narrow,

whitish or ochreous scales, the pleura and the sides of the ventral segments 1—4 with patches of whitish

half wider than the prothorax, flattened on the disc, subparallel towards the base, conjointly rounded at

the apex, the humeri rounded ; the entire surface granulate, the granulations here and there transversely

confluent. Ventral segments coarsely sparsely punctate, 1 and 2 broadly depressed down the middle in

the male.

Length 15-164, breadth 53-63 millim. (d 9.)

Hab. Guatemaa, Cerro Zunil (Champion).

Numerous specimens, varying only in the size of the elytral spots. The upper

surface is sculptured very much as in J. albifrons, which, however, is a much narrower

insect, with immaculate prothorax and elytra. This is one of many species of Hilipus

found by myself in forest-clearings on the Pacific slope of the Cerro Zunil, in the

immediate vicinity of the coffee-plantation known as “ Las Nubes.”

29. Hilipus albifrons, sp.n. (Tab. II. fig. 16, ¢ .)

Elongate-ovate, rather narrow, pitchy-black, the head with a patch of pale ochreous or whitish scales behind

the eyes; the prothorax and elytra covered with small, smooth, shining, granular elevations, which here

and there on the elytra are arranged in transverse irregular series, the interspaces dull and densely

clothed with minute ochreous scales: the under surface, rostrum, aud legs with scattered, narrow, whitish

scales, the ventral segments each with a transverse patch of pale ochreous scales on either side in front.

Elytra elongate, one-half wider than the prothorax, subparallel at the base, conjointly rounded at the

apex, flattened on the disc, the subapical callosities rather prominent, the humeri rounded. Metasternum

comparatively elongate, very coarsely confluently punctured at the sides. Ventral segments very sparsely,

rather coarsely punctate, the first slightly depressed down the middle in the male. .

Hab. Guaremata, Teleman (Champion); Nicaracua, Chontales! (Belé); PANAMA,

Caldera in Chiriqui (Champion).

We possess six specimens of this peculiar species. Apart from the confluent scrobes *,

it is recognizable by the broad, sinuous, sordid ochreous elytral vitte, which extend

from the base to the apex (or are occasionally interrupted), leaving two confluent,

common, diagonal patches on the disc and a transverse one before the apex, the

prothorax also with broad similarly-coloured vitte. The elytra are flattened on the

disc, coarsely seriate-punctate; the prothorax is as long as broad, coarsely rugose,

and with a smooth median carina; the rostrum is strongly curved and slightly longer

than the prothorax; the antenne are inserted before the middle of the rostrum in

both sexes; the second joint of the funiculus is slightly shorter than the first; the

eyes are narrowly separated above and beneath. ‘The first and second ventral segments

are broadly depressed down the middle in the male.

H. velamen, Boh., H. tetanicus and H. designatus, Pasc., are allied forms.

Secrion II.

31. Hilipus securiger, sp. n. (Tab. II. figg. 18, ¢; 184, profile of head ;

18 6, antenna.)

Oblong-ovate, very robust, slightly shining, black, the rostrum and legs more or less piceous; the prothorax

sparsely clothed with fulvous piliform scales, these tending to form a narrow, irregular, sinuous vitta on

each side of the disc and some spots on the flanks, the scutellum with white scales ; the elytra clothed

with brownish-fulvous piliform scales, with very small, irregularly scattered, white or ochreous spots, and an

oblong dark brown patch on the fourth interstice at about the middle; the mesepimera with a patch of

fulvous scales below the humeri; the under surface and legs with widely-scattered, narrow, whitish scales.

Head closely punctured, the eyes large and approximate ; rostrum curved, moderately stout, considerably

longer than the prothorax, rugosely punctured in its basal half, the scrobes extending forwards from the

points of insertion of the antenne to near the tip; antenne inserted at about the middle of the rostrum

in both sexes, joints 1 and 2 of the funiculus subequal in length. Prothorax convex, nearlv as long

as broad, bisinuate at the base, rounded at the sides, abruptly constricted and narrowed in front; con-

spicuously granulate, with an interrupted, smooth, median carina. LElytra one-half wider than the

prothorax, subtruncate at the base, gradually narrowing almost from the shoulders, conjointly rounded

at the apex, the humeri rounded; coarsely seriate-punctate, the interspaces dull, granulate. Lateral

portions of the metasternum coarsely foveolate.

g. First ventral segment, and the metasternum also, very broadly and shallowly depressed down the middle,

this space being pilose and closely punctate, and the fifth segment with a transverse depression at the

apex. Club of the antenne securiform, and the seventh joint of the funiculus furnished with a cluster

of fulvous bristly hairs.

Length 14-163, breadth 63-73 millim. (d 2.)

Hab. Guaremata, Cubilguitz in Vera Paz (Champion) ; Nicaragua, Chontales (Belt,

Richardson).

Two males and three females. A large robust species, distinguishable by the

irregularly-scattered, minute, white or ochreous spots on the elytra, the approximate

eyes, the convex granulated prothorax, and peculiar male-characters. The lateral

grooves of the rostrum (scrobes) extend forwards beyond the points of insertion of the

antenne to near the tip. This character, alone, will separate H. securiger from

the following nearly allied form. The oblong, blackish, velvety patch on the fourth

elytral interstice is not easily seen in abraded specimens. The abnormally-formed

antennal club of the male is a very remarkable peculiarity.

32. Hilipus nigrofasciatus, sp. n. (Tab. II. figg. 19, ¢; 194, profile of

head.)

Oblong-ovate, robust, slightly shining, black or piceous; the prothorax variegated with fulvous scales, the

scutellum and a spot below the humeri densely clothed with white scales, the elytra variegated with

fulvous and blackish scales, the latter forming a broad, irregular, angulated, transverse fascia a little beyond

the middle, the edges of this being here and there indicated by scattered small pure white spots, which

are variable in number, all the scales narrow and piliform; the under surface and legs with scattered,

narrow, whitish scales. Head closely punctured, the eyes large and contiguous; rostrum curved,

moderately stout, considerably longer than the prothorax, thickly punctured towards the base, smooth

towards the tip; antenne inserted at about the middle of the rostrum in both sexes, joints 1 and 2 of

the funiculus subequal in length. Prothorax considerably broader than long, convex, bisinuate at the

base, rounded at the sides, abruptly constricted and narrowed in front; sparsely and finely granulate,

with a more or less distinct, smooth, raised, central line. Elytra convex, about one-half wider than the

prothorax, gradually narrowing from a little below the base, conjointly rounded at the apex, the humeri

rounded; deeply seriate-punctate, the interspaces dull, obsoletely or finely granulate. Lateral portions

of the metasternum coarsely foveolate.

¢. First ventral segment, and the metasternum also, very broadly and shallowly depressed down the middle,

this space being pilose and closely punctate, and the fifth segment with a transverse depression before

the apex.

Found in plenty in Chiriqui. This is one of a group of species characterized by

their large approximate eyes and coarsely foveolate metasternum ; and amongst these

it may be identified by its finely granulate prothorax and irregularly fasciate elytra,

the edges of the fascia indicated here and there by small pure white spots.

A common species within our limits, extending to Northern Mexico and occurring on

both the Atlantic and Pacific slopes. Distinguishable by its broad short form and

the peculiar maculation of the upper surface, the prothorax having a large ochreous

patch at the sides in front and the elytra a similarly-coloured one on the disc before

the apex, and both, in addition, with numerous, scattered, white spots, those on the

middle of the disc of the prothorax and on the base and anterior portion of the elytra

being the most conspicuous. The eyes are almost contiguous above; the rostrum in

the male is short, stout, rugosely punctured, and carinate, it being smoother and more

slender in the female; the first and second joints of the funiculus are equal in length ;

the scutellum is without white scales; and the metasternum is almost smooth. The

first ventral segment is narrowly sulcate down the middle from the base to the apex in

the male. H. multiguttatus (Fabr.) is a nearly-allied form, having the ochreous

patches on the prothorax and elytra replaced by white spots.

34, Hilipus leucostictus, sp. n. (Tab. II. figg. 21, ¢; 21a, profile of head.)

Oblong-ovate, subopaque, black or piceous, the legs and rostrum usually reddish; the upper surface clothed

with brownish-ochreous piliform scales, the elytra sometimes variegated with blackish ones; the pro-

thorax with two white spots on the disc and one on each side in front, and the elytra each with five

conspicuous white spots—four in an oblique series on the disc, extending from the base to near the apex

(the third the largest, and the second and fourth sometimes obsolete or indistinct), and one at the side

below the base,—and often a few other smaller ones scattered along the outer margin posteriorly and on

26 RHYNCHOPHORA.

Six examples. Very like HW. multiguttatus (Fabr.) and H. guttatus, Boh., but with

the elytra truncate at the base and the white spots differently placed, the four on the

disc being almost equidistant and arranged in an oblique line. The single specimen

from Chiapas has the elytra variegated with blackish scales and the second white spot

in the discoidal series absent.

35. Hilipus chiriquensis, sp. n. (Tab. II. fig. 22, ¢ .)

Very like H. leucostictus and differing as follows :—The eyes separated by a narrow space, the rostrum more

coarsely punctured towards the base, the prothorax less rounded at the sides and much more sparsely

granulate, with a longer and more distinct median carina, the serrate punctures on the elytra rounded

(instead of transverse) and more scattered ; the prothorax with six very small white spots—two on the dise,

one on each side in front and one on each flank; the elytra with a small white spot on the fourth interstice

below the base (absent on the left elytron), several others (five or six on each elytron) a little beyond the

middle, these forming an irregular, common, transverse fascia, and a larger one at the sides a short distance

below the humeri.

Length 10, breadth 43 millim. (<¢.)

Hab. Panama, Volcan de Chiriqui (Champion).

One specimen. Perhaps an extreme form of H. leucostictus, differing, however, in

the sculpture of the prothorax and elytra, as well as in the arrangement of the white

spots.

36. Hilipus rotundicollis, sp.n. (Tab. II. fig. 23, ¢.)

Oblong-ovate, dull, black, the legs and rostrum piceous or nigro-piceous; the upper surface clothed with

brownish-fulvous piliform scales, the prothorax with two small whitish or pale ochreous spots on the disc

before the middle and one on each side in front, and the elytra with several small similarly-coloured spots

—one at the base near the shoulder, two (obliquely placed) on the flanks some distanee below the base,

one on the fourth interstice a little beyond the middle, and some others along the outer margin, being the

most distinct,—and each with two velvety-black patches on the disc—one at the middle, subquadrate,

the other towards the apex, irregular, and formed by two interrupted coalescent streaks,—the scutellum

clothed with pale ochreous scales; the under surface with narrow fulvous, and the legs with whitish,

scales. Head closely punctured, the eyes approximate; rostrum comparatively slender, curved, about

one-half longer than the prothorax in the ¢, a little shorter in the 2, thickly punctured to the middle and

smooth beyond ; antenne inserted at the middle of the rostrum, joint 2 of the funiculus slightly longer

than 1. Prothorax convex, a little broader than long, strongly rounded at the sides almost from the

apex to the base, abruptly constricted and narrowed in front; granulate and with a smooth median carina.

Elytra rather short, one-half wider than the prothorax, gradually narrowing from a little below the base,

which is subtruncate, conjointly rounded at the apex, the humeri rounded ; coarsely seriate-punctate and

very finely granulate, the interspaces dull. Lateral portions of the metasternum foveolate. Ventral

segments sparsely punctate, the first depressed and smooth in the middle in the ¢.

Hab. British Hoypuras, Rio Sarstoon (Blancaneauz).

One pair. Closely allied to H. leucostictus and H. chiriquensis, both of which have

similarly-placed whitish spots on the prothorax; but differing from these insects in

having two velvety-black patches on the disc of each elytron, placed one behind the

other, as well as in the very small size and position of the whitish spots. The —

We possess thirteen specimens of this species, distinguishable by its large size, the

scattered series of smooth, prominent, conical tubercles on the elytra, the apices of

the latter being separately acuminate and the subapical callosities prominent, the

sparsely tuberculate, carinate prothorax, &c. The rostrum is longer than the prothorax,

stout, closely punctured towards the base, and has a short longitudinal groove between

the points of insertion of the antenne. The latter are inserted far before the middle

of the rostrum; the second joint of the funiculus is, at most, a little longer than the

first *. The head is deeply foveate between the eyes. ‘The elytra have a large, sub-

triangular, black or brown, velvety patch on the disc about the middle, but this is not

always visible in old or dirty specimens and it is not mentioned by Pascoe. ‘The males

have the first ventral segment depressed in the centre.

39. Hilipus spiculosus, sp. n. (Tab. II. fig. 25, ¢.)

Oblong-ovate, opaque, black, the antennw and tarsi rufo-piceous; the prothorax and elytra densely clothed

with brown scales, the elytra each with a small, elongate-triangular, velvety-black patch on the disc, the

scutellum, rostrum, legs, and under surface with whitish pilitorm scales. Head shallowly foveate between

the eyes, which are somewhat narrowly separated ; rostrum stout, feebly curved, a little longer than the

prothorax, rugosely punctured in its basal half ; antenne inserted before the middle of the rostrum, joint 2

of the funiculus slightly longer than 1. Prothorax convex, transverse, rounded at the ‘sides, constricted

and narrowed in front, strongly bisinuate at the base ; sparsely tuberculate, each of the elevations bearing

a short decumbent seta in front, faintly carinate down the middle. Elytra one-half wider than, and

nearly three times the length of, the prothorax, sinuato-truncate at the base, subparallel anteriorly,

conjointly rounded at the apex, which is slightly emarginate at the suture, the humeri somewhat angulate

externally ; the surface very uneven, coarsely seriate-punctate, the interstices with numerous, scattered,

irregularly-arranged, smooth, conical tubercles, those on the disc large and prominent, each bearing a

Hab. Nicaracua, Chontales (Belt).

One specimen. Allied to the South-American H. muricatus and H. tuberculatus,

but not agreeing with the descriptions of those species. From H. phrynodes it may be

known by its much smaller size, the shorter rostrum, the more convex, more closely

tuberculate, and obsoletely carinate prothorax, the shorter elytra, the apices of which

are very feebly emarginate, &c. H. aspredo, Pasc., is also a very similar form.

Hab. Nicaracua, Chontales 1 (belt).

Recognizable by the coarsely tuberculate prothorax and elytra, the latter each with

two rounded patches of ochreous scales (one at the base close to the shoulder, and the

other some distance beyond the middle near the suture), the head also with a large

rounded patch of similarly-coloured scales. The rostrum is very stout, a little longer

than the prothorax, and coarsely foveolate on the basal half. The antenne are inserted

before the middle of the rostrum; the second joint of the funiculus is slightly longer

than the first. The eyes are somewhat widely separated. The male has the first

ventral segment deeply sulcate down the middle behind. Two specimens only have been

received by us, both of this sex.

27 b, front tibia ; 27 ¢, hind tibia; 28, 9; 28a, front tibia; 280, hind tibia, @ .)

Oblong-ovate, dull, black, somewhat thickly clothed with brownish or fulvous scales, a median line and a

narrow vitta on each side of the prothorax, the scutellum, and the posterior margin of the large, oblique,

velvety-black patch on the disc of each elytron clothed with ochreous scales; the under surface thickly

clothed with intermixed coarse ochreous and piliform whitish scales; the legs with piliform whitish scales.

Head densely punctured, foveate between the eyes, the latter widely separated and not at all prominent ;

rostrum feebly curved, moderately stout, laterally sulcate towards the base; joint 2 of the funiculus

longer than 1. Prothorax subconical, a little broader than long, feebly rounded at the sides, strongly

bisinuate at the base, finely granulate. Elytra rather more than one-half wider than the prothorax,

gradually narrowing from the base, the latter sinuate, the apices considerably produced and conjointly

rounded, the humeri rounded; seriate-punctate and finely granulate, the interstices transversely wrinkled.

3. Rostrum about as long as the prothorax, rugosely punctured to the tip. First ventral segment very

coarsely rugosely punctured and broadly excavate down the middle, and the fifth with a deep, sinuous,

transverse sulcus on each side towards the apex. Tibiew not mucronate, the hind pair strongly sinuous

within and produced at the inner apical angle into a flattened spoon-shaped process, the usual acute claw

absent.

armed with the usual claw at the apex.

Length 10-11, breadth 4-44 millim. (d 2.)

Hab. Mexico, Misantla, Jalapa (Hoge).

Six specimens. Differs from the other Central-American species of the genus in the

form of the hind tibie of the male, these being strongly sinuous and produced at the

inner apical angle into a flattened, spoon-shaped process, the usual claw being entirely

absent in this sex. All the tibiee have two long, matted, spine-like pencils of hair at the

apex. The velvety-black spot on each elytron is more obliquely placed than in any of

the other similarly-coloured Hilip: inhabiting our region.

This is a species with velvety-black markings on the prothorax and elytra, there

being a sinuous streak on either side of the disc of the former, and an elongate patch

of variable extent on the disc of each of the latter (this being often broken up and

reduced to narrow streaks), the elytral markings extending more or less posteriorly so

as to include the various fulvous or whitish discoidal spots; the prothorax has a

fulvous stripe on each side exterior to the black one, and on the flanks there is a large,

sinuous, white-edged, fulvous patch ; the scutellum is clothed with white scales; the

elytra have each a small fulvous spot at the base and an oblique white patch on the

outer margin below the shoulder; the rest of the upper surface is thickly clothed with

minute, narrow, chocolate-brown scales. The rostrum is curved, closely punctured

from the base to the apex, moderately stout and considerably longer than the prothorax

in the male, longer and more slender in the female. The head is not foveate between

the eyes, which are narrowly separated. The first and second joints of the funiculus

are subequal in length. ‘he disc of the prothorax and the base of the elytra are

obsoletely granulate. The first ventral segment is unimpressed in both sexes.

43. Hilipus pulchellus, sp. n. (Tab. III. fig. 2, 2.)

Oblong-ovate, opaque, black, the tarsi rufescent, the upper surface somewhat thickly clothed with minute,

rounded, chocolate-brown scales, the base of the rostrum, the head, the front of the prothorax, and the

scutellum clothed with bright fulvous piliform scales; the prothorax with three velvety-black streaks,

one along the middle of the disc and one on each side of it, the latter irregular, more or less interrupted,

and divided at the base by a curved longitudinal line of fulvous or whitish scales, the flanks also with a

sinuous line of similarly-coloured scales in front; the elytra each with a triangular mark at the base,

one-half wider than the prothorax, flattened along the suture anteriorly, gradually narrowing from the

base, the apices conjointly rounded, the humeri rounded externally and slightly hollowed in front, the

third interstice somewhat costate towards the base; seriate-punctate and sparsely granulate, each of the

smooth elevations bearing a short decumbent seta behind. First ventral segment somewhat deeply

depressed along the middle behind in the male.

This species may be recognized by the large velvety-black mark on the disc of each

elytron, this being triangular in shape and extending downwards at the inner angle,

often meeting a similarly-coloured longitudinal streak on the third interstice, followed

by a large ochreous or greyish evanescent patch. ‘The head is shallowly canaliculate

between the eyes. The rostrum is short and broad, carinate, and not longer than the

prothorax; the scrobes are lateral and in great part visible from above. The prothorax

has a narrow oblique line of greyish or ochreous scales on each side of the disc. The

males have a dense transverse patch of ochreous scales (sometimes divided into two) at

the middle of the posterior margin of the first ventral segment, which is unimpressed

in both sexes. The South-American specimens I have seen are considerably larger than

any of the nine obtained in our region.

Chiefly distinguishable by its very large size, broad elytra, and granulate upper

surface, which is thickly clothed with intermixed griseous and brownish scales, the

elytra each with a large, oval or subtriangular, velvety-black patch on the outer part of

the disc and some similarly-coloured markings near the apex. The rostrum is very

The fourteen specimens received of this species show considerable variation in the

size and shape of the large velvety-black patch on the disc of each elytron, and also

in the extent of the encircling ring of ochreous or ashy scales: in four (out of the

seven) examples obtained north of Nicaragua the black patch is reduced in size,

rounded, and with, at most, a faint line of ashy scales round it; in the two individuals

from Chiriqui, as in some of those from Chontales, the black patch is very large and

angular, and encircled (except on the outer edge) by a rather broad line of ochreous

scales. In fresh specimens there is an angulated line of ochreous or greyish scales on

each side of the disc of the prothorax. The rostrum is very stout, the antenne

inserted near the tip; the eyes are somewhat distant; the prothorax and elytra are

granulate ; the first ventral segment is flattened or very faintly depressed in the middle

in the male. A typical specimen from Nicaragua is figured.

velvety-black patch on the disc of each elytron beyond the middle, this patch bordered

with a narrow line of ochreous scales, and sometimes followed by a small triangular

one. The rostrum is stout, feebly curved, considerably longer than the prothorax in

the male, smoother at the apex and still longer in the female, rugose and 5-carinate

towards the base. The head is sulcate between the eyes, which are very narrowly

separated. The prothorax and elytra are sparsely granulate, each of the smooth,

tuberculiform, elytral elevations bearing a short decumbent seta; they have the surface

clothed (except upon the velvety patch) with minute, rounded, brownish scales. The

scutellum is clothed with whitish scales. The males have the metasternum and first

ventral segment very broadly and shallowly depressed down the middle.

48. Hilipus flavolineatus, sp. n. (Lab. III. figg. 7, 2; 7a, profile of head.)

Oblong-ovate, opaque, black, somewhat thickly clothed with very minute, rounded, brown scales; the elytra

each with a very large, oval, velvety-black, lateral patch, extending inwards to near the second row of

punctures and limited internally by a line of pale ochreous scales, which is continued forwards round the

humeri to the base of the sixth interstice, the scutellum also clothed with pale ochreous scales ;

the under surface and legs very sparsely clothed with piliform ochreous scales. Head foveate between the

eyes, which are rather widely separated ; rostrum dull, strongly curved, stout, considerably longer than

the prothorax, sparsely, finely punctate, smoother towards the tip, with a smooth narrow space down the

middle; antenne inserted at the middle of the rostrum, joints 1 and 2 of the funiculus subequal in

length. Prothorax transverse, convex, rounded at the sides, abruptly constricted and narrowed in front,

very sparsely granulate, the elevations transverse and not very prominent. Elytra one-half wider than

the prothorax, sinuate at the base, subparallel to near the middle, conjointly rounded at the apex, but

with the sutural angles somewhat pointed, the humeri rounded externally and concave in front; finely

seriate-punctate, the punctures becoming coarse towards the base, the interstices (except upon the

velvety patch) with a single, widely-scattered, irregular series of rather prominent granular elevations,

each of which bears a short decumbent seta on its posterior edge. Metasternum very sparsely foveolate

towards the sides. Ventral surface almost smooth, the first segment unimpressed.

Two specimens. Not unlike the South-American H. zoubkofii, H. ocellatus, &c.,

but with the velvety-black patch on each elytron very large and lateral, the interstices

each with a single series of scattered, setigerous, granular elevations. From H. intensus,

which has similar minute scales on the upper surface, it may be distinguished by the

more curved non-carinate rostrum, the much larger and differently-shaped velvety

patches on the elytra (which are not bordered externally with a line of ochreous

scales), the more widely separated eyes, &c.

Hab. Mexico, Jalapa ({Hége); Panama, Bugaba, Volcan de Chiriqui (Champion).

Three specimens, probably including both sexes. Very like H. flavolineatus, but

slightly shining, the prothorax a little less constricted in front and more finely

granulate, the elytra more closely and not so coarsely granulate, with the humeri less

hollowed in front, the velvety-black patches less elongate, and the line of ochreous

scales bordering them internally not extending sinuously forward to the base, the

brownish scales on the prothorax and elytra more elongate.

50. Hilipus decoratus, sp.n. (Tab. III. fig. 9, ¢.)

Oblong-ovate, opaque, black, the upper surface thickly clothed with griseous and brown scales, the latter

usually forming two obscure vitte on the disc of the prothorax and various spots on the disc of the

elytra, each elytron with a large rounded or rounded-triangular velvety-black. patch on the outer part

of the disc and a similarly-coloured triangular mark near the suture before the apex ; the under surface

thickly squamose, the legs with piliform scales. Head not or feebly sulcate between the eyes, which are

somewhat widely separated; rostrum stout, in the ¢ slightly curved, about as long as the prothorax,

and closely punctured and laterally sulcate towards the base, in the 2 longer, more curved, and smoother

at the tip; joint 2 of the funiculus slightly longer than 1. Prothorax broader than long, rounded at the

sides, narrowed in front, very sparsely granulate, the granules larger on the disc than on the flanks.

Elytra a little more than one-half wider than the prothorax, gradually narrowing from the base, the

latter sinuato-truncate, conjointly rounded at the apex, the humeri swollen, rounded externally; the

surface uneven, the third interstice interruptedly costate and the subapical callosities prominent, seriate-

punctate, the interstices with widely-scattered, smooth, prominent tubercles, each of these bearing a short,

pallid, decumbent seta.

3. First ventral segment hollowed down the middle, the depression limited on either side posteriorly by a

dense cluster of ochreous scales, and the fifth with a deep transverse sulcus on each side before the apex.

confined to the Pacific slope, and was found in plenty at Zapote, and the typical form

to the Atlantic slope. H. biplagiatus, Boh., which looks very distinct at first sight,

merely differs from H. circuliferus in having the velvety-black spot on the disc of the

elytra reduced in size, or broken up into spots, and not encircled by a line of greyish

or ochreous scales. Of the forty specimens before me, twenty-two belong to the

former. From H. cynicus the present species may be separated by its much smaller

size, the less prominent humeri, &c.

52. Hilipus atrosignatus, sp.n. (Tab. III. fig. 12.)

Oblong-ovate, subopaque, black, the head, rostrum, and legs rufo-piceous, the antennee and tarsi rufescent ;

the upper surface variegated with whitish and brown scales, the whitish ones forming a short median

and a sinuous submarginal line on the prothorax, a spot on the scutellum, and a line round the large,

rounded, velvety-black patch on the disc of each elytron, the latter also with a small velvety-black spot

on the subapical callus; the under surface and legs sparsely clothed with whitish and ochreous piliform

scales. Head foveate between the eyes, which are rather narrowly separated; rostrum stout, feebly

curved, a little longer than the prothorax, thickly punctured and laterally sulcate towards the base ;

joint 2 of the funiculus slightly longer than 1. Prothorax transverse, strongly bisinuate at the base,

rounded at the sides, constricted and narrowed in front; sparsely, coarsely granulate, Elytra rather

short, one-half wider than the prothorax, parallel towards the base, conjointly rounded at the apex, the

humeri rounded externally and hollowed in front; seriate-punctate and sparsely, coarsely granulate,

the smooth granular elevations each bearing a short decumbent seta. First ventral segment un-

impressed.

Length 93, breadth 44 millim.

Hab. Nicaragua, Chontales (Belt).

One specimen, probably a male. A second example (?%), found by myself at

Bugaba, Panama, belongs to this or to a very closely-allied species. It differs from

the Nicaraguan insect in having the prothorax and elytra much more finely granulate,

the interstices of the latter transversely wrinkled towards the base, the rostrum mote

elongate.

53. Hilipus asperatus, sp.n. (Tab. III. fig. 13.)

Oblong-ovate, black, the head, rostrum, antenne, and legs rufo-piceous ; the prothorax and elytta somewhat

thickly clothed with intermixed fulvous and whitish scales, the whitish ones on the prothorax coarse and

piliform, the elytra each with a triangular, brownish-black, velvety patch on the disc and a transverse

similarly-coloured streak near the apex; the scutellum with whitish scales; the under surface and legs

sparsely clothed with ochreous and whitish piliform scales. Head foveate between the eyes, which are

rather narrowly separated; rostrum short and very stout, feebly curved, very little longer than the

prothorax, towards the base rugosely punctured and laterally sulcate; joints 1 and 2 of the funiculus

subequal in length. Prothorax convex, much broader than long, rounded at the sides, considerably

narrowed in front, strongly bisinuate at the base, coarsely granulate, without trace of median carina.

Elytra comparatively short, one-half wider than the prothorax, sinuate at the base, gradually narrowing

from a little below the humeri, the latter rounded externally, the apices conjointly rounded; the surface

uneven, coarsely seriate-punctate, the interstices with scattered series of smooth tubercles, those on the

third interstice large, each bearing a rather long decumbent seta, the subapical callosities prominent,

Ventral segments 1-4 very sparsely, minutely punctate, the first unimpressed.

Length 9, breadth 4 millim.

Hab. Guaremaua, Cubilguitz in Vera Paz (Champion).

One specimen, no doubt a male, the rostrum being very short. Recognizable by

the coarsely tuberculate, transverse thorax, the rather stout, tuberculate, setigerous

elytra, each of which has a small triangular, dark, velvety patch on the disc, &c.

Compared with H. spiculosus it is less elongate and much smaller, the elytra are

narrower and more finely tuberculate, the tubercles on the prothorax, on the contrary,

being larger.

54. Hilipus costaricensis, sp. n. (Tab. III. fig. 14.)

Oblong-ovate, black, shining, the rostrum and the legs in part piceous, the tips of the tarsi and the scape

rufescent ; the upper surface variegated with rather coarse, narrow, ochreous and whitish scales, the

elytra each with a very large, black, subtriangular, lateral patch (extending from a little below

the shoulder to near the tip, and inwards to the third interstice) and a small transverse black mark

before the apex ; the legs and under surface with scattered, coarse, piliform, whitish and ochreous scales.

Head closely punctate, not foveate between the eyes, the latter large and somewhat narrowly separated ;

rostrum moderately stout, feebly curved, much longer than the prothorax, shining, sparsely punctate ;

antenne inserted considerably before the middle of the rostrum, joints 1 and 2 of the funiculus

subequal in length. Prothorax convex, transverse, rounced at the sides, constricted in front, and

and transverse in shape on the disc, in the centre of which is a smooth oblong prominence. Elytra

one-half wider than, and three times the length of, the prothorax, subtruncate ,at the base and

subparallel thence to the middle, flattened on the disc anteriorly, the humeri rounded, the subapica

callosities prominent, the apical portion somewhat abruptly declivous, the apices conjointly rounded ;

deeply seriate-punctate, the interstices slightly convex and each with a scattered series of smooth

tubercles. Beneath very sparsely, finely punctate, the sides of the metasternum foveolate ; metasternum

short, deeply sulcate in the middle behind. Legs comparatively short; tibisze mucronate, the claw

arising from near the outer angle.

Length 83, breadth 4 millim. (2.)

Hab. Costa Rica, Pital del Naranjo (Biolley, in Mus. Brit.).

Two specimens. This species is perhaps nearest allied to H. asperatus, H. nevulus,

and If. atrosignatus, but has relatively shorter and broader elytra, the black patch

very large and laterally placed, a long rostrum, &c. The shorter prothorax, more

parallel elytra, &c., separate it from H. decoratus. The white scales on the upper

surface are chiefly confined to a space on the disc of the elytra beyond the middle, the

scutellum, and a line down the middle of the prothorax.

55. Hilipus trinotatus, sp.n. (Tab. III. figg. 15; 15, profile of head &c.)

Elongate-ovate, black, the prothorax (except along the middle in front), scutellum, and elytra densely

clothed with flavo-cinereous scales, the disc of the prothorax and of that of the basal half of the elytra

mottled with brown, the elytra with a very large, subtriangular, sharply-defined patch at the sides a

little beyond the middle and a common apical patch brownish-black ; the head, rostrum, under surface,

and legs sparsely clothed with piliform greyish scales. Head foveate between the eyes, which are rather

widely separated; rostrum exceedingly stout, moderately curved, about as long as the prothorax,

closely punctured at the sides towards the base; antenna stout, inserted at about the middle of the

rostrum, joints 1 and 2 of the funiculus subequal in length, the following joints short and moniliform,

the club ovate and about as long as the last four joints of the funiculus united. Prothorax convex,

about as long as broad, much rounded at the sides, constricted and narrowed in front and narrowed

behind; the surface with widely-scattered, smooth, rounded granules, which become more crowded on the

dise behind and are flattened in front. Elytra comparatively elongate, subparallel in their basal half,

one-fourth wider than the prothorax, flattened on the disc, conjointly rounded at the apex, but with the

sutural angles somewhat pointed, the humeri rounded; coarsely seriate-punctate, the interstices

narrow, transversely rugose, and also very sparsely but conspicuously granulate. First ventral segment

faintly depressed in the middle behind. ‘Tibia acutely mucronate, the curved apical claw also long.

Length 133, breadth 5 millim.

Hab. Nicaracva, Chontales (Belt).

One specimen, probably a female. A very distinct species, not unlike H. jocosus,

but more elongate, densely squamose (the scales completely hiding the sculpture, with

the exception of the smooth granular elevations), the antenne stouter, with a shorter

club, the prothorax more rounded at the sides, the anterior tibie strongly mucronate

at the tip, &c.

Found in plenty at Bobo and Bugaba, and occurring on both the Atlantic and.

Pacific slopes of Guatemala. Distinguishable by its rather elongate shape and

greyish-white clothing, the elytra each with a large, subtriangular, postmedian, lateral

patch and an irregular transverse fascia immediately before the apex velvety-black,

the lateral patch bordered posteriorly with ochreous scales, the prothorax with a

more or less distinct, curved, whitish line on each side of the disc, the two lines

becoming confluent before the apex. The entire upper surface is sparsely granulate,

the elytra flattened towards the suture. In the males the first ventral segment

is slightly emarginate at the apex, and furnished with a dense patch of ochreous

and brown seales in the centre behind, the other scales on the ventral surface being

white.

57. Hilipus quadrinodosus, sp. n. (Tab. ITI. figg. 17, ¢ ; 17 a, profile of

elytra.)

Oblong-ovate, dull, piceous, more or less mottled with black, the upper surface variegated with a somewhat:

dense clothing of rather coarse whitish and fulvous scales, the elytra also with intermixed dark brown

at the sides. Elytra one-half wider tham the prothorax, subparallel in their basal half, strongly sinuate:

at the base, conjointly rounded at the apex, the humeri rounded; coarsely seriate-punctate and

conspicuously granulate, the interstices transversely wrinkled, the third shortly costate at about

one-third from the apex and then abruptly declivous, the blunt tooth thus formed being as prominent

as the subapical callus, these elevations limiting the flattened space on the apical declivity.

Metasternum transversely strigose. Ventral segments finely, shallowly punctate, the first sometimes

notched in the centre of the apical margin. _

Length 114-123, breadth 53-53 millim. (d @-)

Hab. Guatemata, Rio Maria Linda, Pacific slope (Champion) ; Nicaragua, Chontales

(Belt).

Four specimens. Not unlike H. jocosus, but less elongate and relatively broader ;

the elytra more coarsely granulate, with the third interstice raised into a blunt tooth

posteriorly, and the velvety-black markings consisting of a transverse series of three

or four small streaks on the disc at about one-third from the apex, the streak on the

fifth interstice being longer than the others; the metasternum transversely strigose.

The quadrinodose apical declivity of the elytra separates the present species from the

other allied Central-American forms.

Three specimens. Very like /. jocosus, but less elongate, the eyes somewhat

narrowly separated, the prothorax more transverse, the elytral markings very different,

&c. The common, subapical, white fascia on the elytra is broad and sharply limited

in front, and usually preceded by a transverse patch of blackish scales. There is also

a broad dense band of white scales extending along the pro- and mesopleura, this

Hab. Nicaragua, Chontales (Belt).

Three specimens. Distinguishable by the two conspicuous velvety-black patches

on each elytron—one median, transverse; the other oblong and subapical. From

H. jocosus and other allied species it may be recognized by the numerous, smooth,

small, shining tubercles on the prothorax and elytra, the variegate and rather coarse

squamosity, and the shape of the velvety-black patches on the elytra.

60. Hilipus nevulus. (Tab. III. fig. 20.)

Heilipus nevulus, Mann. in Schénh. Gen. Cure. iii. p. 188°.

Oblong-ovate, shining, nigro-piceous or black; the upper surface between the smooth granular elevations

Heilipus decussatus, Boh. in Schénh. Gen. Cure. vil. 2, p. 93°.

Hab. Mexico (coll. Chevrolat !), Toxpam (Saldé). —

In this species the prothorax has an oblique, angulated, white vitta on each side

of the disc, and the elytra have a common, interrupted, X-shaped, white mark

One specimen. This insect seems to be allied to the Brazilian H. leoninus, Boh.

The following species, H. lentiginosus, is not unlike it, and has similar male-characters.

The tibial claw in both sexes arises from near the outer apical angle, the tibie thus

being ‘“ unguiculate” (instead of “ mucronate”), in the sense of Lacordaire.

head.)

Oblong-ovate, black, the head, rostrum, legs, and antenne rufo-piceous; the prothorax and elytra

variegated with a dense clothing of small fulvous and whitish scales, the latter forming an irregular

patch on the disc of the prothorax and another on each flank, and an oblique fascia on the disc of each

elytron before the middle and a transverse one beyond it, the elytra also with a curved, longitudinal,

velvety-black streak on the disc between the fascie and some similarly-coloured marks near the apex;

at the sides, constricted and narrowed in front, strongly bisinuate at the base; the surface uneven, and

very sparsely, irregularly, finely granulate. Elytra fully one-half wider than the prothorax, parallel

in their anterior half, sinuato-truncate at the base, slightly emarginate at the apex, flattened along the

suture, the humeri somewhat angular externally ; coarsely seriate-punctate, the interstices with widely-

scattered, irregularly-arranged, smooth granules, each of these bearing a short decumbent seta; the

subapical callosities, and the third, fifth, and seventh interstices at about the middle, angularly or

declivity. Ventral surface very finely punctate, the first suture feebly bisinuate.

Length 114, breadth 5 millim. (?¢.)

Hab. Payama, Bugaba (Champion).

One specimen only of this curious form has been obtained. There is a Brazilian

Oblong-ovate, slightly shining, piceous or rufo-piceous, maculated with black; the upper surface variegated

- with a somewhat dense clothing of small ashy, fulvous, and brownish scales, the ashy scales tending to

form three streaks or a cruciform patch on the disc of the prothorax and two interrupted fascize on the

elytra, the fulvous ones predominating on the head, on the sides of the prothorax, and on the scutellum,

Three specimens. Closely allied to H. guadrinodosus, with which it agrees in the

transversely strigose metasternum; but smaller and narrower, with more prominent

humeri; the elytra less uneven and without a prominence on the third interstice, the

velvety-black spot placed further from the apex ; the rostrum not so stout. The strigose

surface of the metasternum looks as if it might be used for stridulatory purposes. ‘The

dense brush of long hairs on the first and second joints of the anterior tarsi in the male

is a very remarkable character.

66. Hilipus punctipectus, sp. n.

Extremely like H. strigipectus, but differing as follows:—The prothorax with a rather large patch of fulvous

scales on each side at the base, the velvety-black patch on the disc of each elytron a little more elongate,

the piliform scales on the under surface not so coarse, longer, and more abundant; the rostrum (¢)

stouter and a little longer, densely ragose to the tip, so as to appear dull; the metasternum clothed with

piliform scales like the rest of the under surface, closely and simply punctate, shallowly sulcate down the

middle; first ventral segment( ¢ ) impressed down the middle from the base to the apex ; first and second

joints of the anterior tarsi (¢) without brushes of long hair; the intermediate and hind tibie without

additional long hairs on the inner side towards the apex.

Length 11, breadth 45 milim.

spot on the disc beyond the middle, this spot surrounded by a line of ochreous or

whitish scales, the rest of the upper surface being sparsely clothed with narrow greyish

or brownish scales. The first two ventral segments are convex, and unimpressed in

both sexes. :

HILIPUS. 43

68. Hilipus cxcus, sp. n. (Tab. III. fig. 27, 2.)

Heilipus cecus, Chevyr. in litt.

Oblong-ovate, opaque, the granular elevations only shining, black, thickly clothed with brownish piliform

scales, with a few whitish ones intermixed, these latter tending to form a sinuous interrupted line on

either side of the prothorax, the elytra variegated with blackish scales, and each with a small, conspicuous,

oblong or oval, velvety-black patch on the fourth interstice slightly beyond the middle, the scutellum

clothed with white or pale ochreous scales; the under surface and legs with scattered, narrow, whitish

scales. Head foveate between the eyes, which are rather narrowly separated ; rostrum slightly curved,

moderately stout, considerably longer than the prothorax, thickly punctured towards the base; antennw

inserted before the middle of the rostrum, joints 1 and 2 of the funiculus subequal in length. Prothorax

much broader than long, rounded at the sides, constricted and much narrowed in front, sparsely granulate,

the elevations smooth and transverse, without trace of median carina. Elytra one-half wider than the

prothorax, subparallel in their basal half, conjointly rounded at the apex, the humeri rounded ; seriate-

punctate, the interstices with smooth, transverse, granular elevations, and transversely wrinkled towards

the base. Metasternum foveolate along the outer margins. Ventral segments 1 and 2 rather convex,

1-4 sparsely and finely, and 5 coarsely, punctate, 1 unimpressed in the male.

Length 10-12, breadth 43-53 millim. (¢ Q.)

Hab. Mexico, Toxpam (Sallé), Jalapa (Hoge, Trujillo).

Sent in plenty from Jalapa. ‘The specimens in the Sallé collection are labelled with

the MS. name H. cewcus, Chevr. Allied to H. bioculatus, from which it differs in the

opaque and more densely squamose upper surface, and in having the smooth, transverse,

granular elevations on the elytra extending to the base, instead of being confined to

the apical declivity, those on the prothorax being also more prominent. No definite

male-characters are visible beneath. There is a WHilipus from Brazil very like

H. cecus in Dr. Sharp’s collection labelled H. fallax, Sch., but this insect has the

scales on the upper surface much less elongate, and the elevations on the elytra more

transverse.

69. Hilipus unifasciatus, sp.n. (Tab. IV. fig. 1, 2.)

Heilipus unifasciatus, Chevr. in litt.

Oblong-ovate, shining, black; variegated above with very small widely-scattered patches of whitish or

ochreous, rather coarse piliform scales, and also with very minute, loosely-attached, narrow, brownish

ones, the larger scales sometimes aggregated so as to form a narrow, irregular, sinuous, postmedian

fascia on the elytra and a short median line at the base of the prothorax and a sinuous one on each side

of its disc, the scutellum with whitish scales; the under surface very sparsely, and the legs more thickly,

clothed with whitish piliform scales. Head closely punctured, foveate between the eyes, which are

narrowly separated; rostrum stout, feebly curved in the ¢, nearly as long as the head and prothorax,

and closely or rugosely punctured towards the base, in the ? smoother at the tip and a little more

elongate, the antennal grooves widely separated at the base beneath; joints 1 and 2 of the funicuius

equal in length. Prothorax transverse, rounded at the sides, narrowed and constricted in front and

narrowed behind, strongly bisinuate at the base; sparsely granulate at the sides and towards the base, a

space on the anterior part of the disc being impressed with intermixed, minute, and rather coarse punc-

tures. Elytra one-third wider, and about two and one-half times longer, than the prothorax, sinuate at

the base, gradually narrowing from the rounded, somewhat swollen humeri, conjointly rounded at the

apex ; deeply seriate-punctate, the punctures becoming finer and more scattered towards the apex,

the interstices slightly wrinkled towards the base and in some specimens finely granulate on the apical

segments 1-4 very sparsely, minutely punctate, 1 slightly depressed in the middle in the male.

Length 74-11, breadth 33-5 millim. (d @.)

Hab. British Honpvras, Rio Sarstoon (Blancaneaux) ; GuaTemaua, Panzos (Conradt,

Champion), Chacoj, San Juan, Senahu (Champion); Nicaracua, Chontales (Beit) ;

Panama, Bugaba, Volcan de Chiriqui (Champion).—CotomBia (Mus. Brit.).

Var. The squamosity of the upper surface a little more abundant; the elytra more rugose towards the base,

with the interstices faintly granulate, the punctures usually very coarse on the basal half. (¢ 2.)

Hab. Mexico, Sierra de Durango, Amatan, Motzorongo (Blot), Toxpam (Sallé),

Misantla (Hége).

Of this variable species, which may be known by its shining and very sparsely

squamose surface (approaching JI. bioculatus in this respect), we have received a long

series of specimens from within our limits, those from the Sallé collection being

labelled H. unifasciatus, Chevr. There is an example of it, too, from Colombia, in

Dr. Sharp’s collection, ticketed H. indistinctus, Jekel. Very similar forms seem to be

generally known under the name of H. clavipes (Fabr.); but I cannot reconcile our

insect with Boheman’s description of the Fabrician species, in which he says that it

is of the length of Cleonus sulcirostris, and has the elytra four times as long as the

thorax, &c. The minute brownish scales are easily abraded, the larger ones only being

conspicuous. Compared with H. bioculatus, the present species is relatively narrower.

70. Hilipus cinctipennis, sp. n.

Oblong-ovate, subopaque, black, the upper surface clothed with very fine, piliform, fulvous or brownish scales,

the elytra each with a rather broad transverse fascia of coarser whitish or ochreous scales on the disc a

little beyond the middle; the under surface and legs with scattered, whitish, piliform scales. Head deeply

foveate between the eyes, which are somewhat widely separated ; rostrum stout, feebly curved, short, not

longer than the prothorax, closely punctured, smoother at the apex and along the middle; joints 1 and 2

of the funiculus equal in length. Prothorax broader than long, moderately rounded at the sides, strongly

bisinuate at the base, narrowed and constricted in front ; subgranulate and also punctate at the sides and

base, a space on the anterior part of the disc irregularly punctured (the entire surface, when viewed under

a strong lens, densely minutely reticulate). Elytra about one-third wider than, and three times the

length of, the prothorax, subparallel in their basal half, somewhat compressed at the sides before the

middle, strongly sinuate at the base, conjointly rounded at the apex, the humeri rounded and a little

swollen; seriate-punctate, the punctures on the apical declivity almost obsolete and replaced by scattered

granular elevations, the interstices transversely wrinkled towards the base. Ventral segments 1-4 very

sparsely, minutely punctate, 1 flattened or faintly depressed in the middle.

Length 9-113, breadth 33-4? millim. (¢.)

Hab. Mexico (Sailé); Guatemauta, Panzos (Champion); Nicaragua, Chontales

(Janson).

A single specimen from each locality (the one from Mexico being immature),

evidently males, the rostrum being short and stout in all of them. Very like

H. unifasciatus, but less shining, the prothorax and elytra without small scattered

patches of whitish scales, the fascia on the elytra broader, more transverse, and more

distant from the apex, the punctures on the actual declivity almost obsolete and

replaced by scattered granules, the prothorax less rounded at the sides. ‘he tibie-

are sharply mucronate in the Mexican example, feebly so in the others.

71. Hilipus crux-alba, sp. n. (Tab. IV. fig. 2, 2.)

Oblong-ovate, somewhat shining, black or pitchy-black, variegated above with small scattered patches of

coarse, piliform, fulvous scales, and also with very minute brownish ones, the elytra each with a large,

irregular, cruciform patch of intermixed coarse, whitish and fulvous scales on the disc beyond the middle ;

the pleura with coarse, and the rest of the under surface and the legs with piliform whitish scales.

Head closely punctate, deeply foveate between the eyes, the latter rather widely separated; rostrum

curved, in the ¢ stout, not longer than the prothorax, and rugosely punctured to the tip, in the 9

more slender, as long as the head and prothorax, and smoother towards the tip, the antennal grooves

rapidly descending and somewhat narrowly separated at the base beneath; antenne inserted near the apex

of the rostrum in the ¢, much further back in the 9, joints 1 and 2 of the funiculus equal in

length. Prothorax convex, transverse, rounded at: the sides, constricted and narrowed in front, strongly

pisinuate at the base, broadly and deeply emarginate at the apex (so as to appear to have rather prominent

ocular lobes); somewhat closely granulate, the apex closely punctate, and sometimes with a faint,

abbreviated, median carina. Elytra one-half broader than, and two and one-half times the length of, the

prothorax, subparallel in their basal half, conjointly rounded at the apex, the humeri rounded; very

coarsely and closely seriate-punctate, the interstices narrow, somewhat raised, transversely wrinkled, and

finely granulate. Beneath very sparsely, minutely punctate, the sides of the metasternum and the apex

of the first ventral segment foveolate, the first segment unimpressed in both sexes.

Length 9-10, breadth 4-43 millim. (¢ 9.)

Hab. Mexico, Jalapa, Misantla (Hoge), Temax in North Yucatan (Gaumer).

Nine specimens. It is possible that these may prove to be a form of H. tugusti,

which is also said to have somewhat prominent ocular lobes to the prothorax; but as

Boheman does not mention the granulation of the elytra, &c., our insect must be treated

as distinct for the present. The rapidly-descending scrobes, the closer granulation of

the upper surface, the large cruciform patch on the disc of each elytron, the more

deeply emarginate apex of the prothorax, &c., readily separate H. crux-alba from

H. unifasciatus. H. albosignatus, Kirsch, from Bogota, must also be a nearly-allied

form.

72. Hilipus scutellaris, sp.n. (Tab. IV. fig. 3.)

Oblong-ovate, slightly shining, black, the head, rostrum, legs, and antennz more or less piceous or rufo-piceous,

the upper surface variegated with narrow fulvous and blackish scales ; the elytra each with a subtriangular

velvety-black or dark brown patch on the disc beyond the middle, this being followed by two or three

small pure white spots, and sometimes preceded by a single one, and with several small white spots along

the outer margin, there being also one on the mesepimera; the prothorax with a small white spot at the

base on each side and one in front of the anterior cox, the scutellum also clothed with white scales ;

the under surface and legs very sparsely clothed with narrow whitish scales. Head closely punctured,

foveate or sulcate between the eyes, which are somewhat narrowly separated ; rostrum curved, moderately

stout, much longer than the prothorax, thickly punctured to the middle; antenn inserted near the

middle of the rostrum, joint 2 of the funiculus a little longer than 1. Prothorax convex, broader than

long, bisinuate at the base, rounded at the sides, narrowed and constricted in front, sparsely conspicuously

granulate, without trace of central ridge. Elytra one-half wider than the prothorax, subparallel at the

base, conjointly rounded at the apex, the humeri rounded; seriate-punctate and finely granulate, the

interstices transversely wrinkled. Metasternum deeply foveate along the outer edge. Venter convex

towards the base, segments 1-4 almost smooth, unimpressed.

Length 11-18, breadth 43-5} millim.

Hab. Nicaracva (Sallé), Chontales (Belt); Panama, Bugaba, Volcan de Chiriqui

(Champion).

Six examples, probably including both sexes, the males of some of the allied forms

(H. bioculatus and H. cecus) also having the first ventral segment unimpressed. ‘The

present species is very like H. nigrofasciatus; but is narrower and less robust, the eyes

are not contiguous above, the prothorax has two white spots at the base and is more

coarsely granulate, the outer edges only of the metasternum are foveolate, &c.

73. Hilipus pulverulentus, sp.n. (Tab. IV. fig. 4.)

Oblong-ovate, shining, rufo-piceous, the head, rostrum, and tarsi rufescent; the upper surface (the head

excepted) somewhat thickly clothed with tawny scales, the legs and under surface with long piliform scales.

Head foveate between the eyes, which are somewhat widely separated ; rostrum moderately stout, curved,

one-half longer than the prothorax, closely and finely punctured towards the base; antenne inserted at

about the middle of the rostrum, joints 1 and 2 of the funiculus subequal in length, the club longer

than the five preceding joints united. Prothorax much broader than long, convex, rounded at the sides,

constricted and considerably narrowed in front, strongly bisinuate at the base; the surface, except for a

narrow space along the middle behind, finely and rather sparsely granulate, the interspaces densely,

minutely punctate. Elytra one-fourth. wider than the prothorax, strongly sinuate at the base, subparallel

in their basal half, conjointly rounded at the apex, the humeri rounded ; seriate-punctate, the interstices

transversely wrinkled and finely granulate. First ventral segment faintly depressed down the middle

behind.

Length 124, breadth 5 millim.

Hab. Nicaragua, Chontales (Belt).

One specimen, probably a female, though the first ventral segment is distinctly

impressed in the middle. Chiefly distinguishable by the dense uniform tawny clothing

of the prothorax, scutellum, and elytra, the strongly-sinuate base of the latter, and the

finely-granulated upper surface. H. pulverulentus is closely allied to the South-

American H. pertyi, Schonh. (=rufipes, Boh.), but differs from it in having the

squamosity of the elytra uniformly tawny (instead of variegate with black and white),

and the elytra themselves less elongate.

74. Hilipus fulvisquamis, sp.n. (Tab. IV. fig. 5, 2.)

Oblong-ovate, moderately shining, rufo-piceous, the rostrum and legs sometimes rufescent; the upper surface

somewhat thickly clothed with bright fulvous piliform scales, which on the pronotum are concentrated

into two broad oblique vitte: (a space down the middle and the flanks being very sparsely squamose); the

elytra with a small spot or transverse mark on the disc a little beyond the middle, sometimes extending

outward to near the margin, and usually a small spot immediately behind the subapical callosities, black ;

the legs and under surface sparsely clothed with whitish and fulvous piliform scales. Head foveate

between the eyes, which are somewhat widely separated ; rostrum feebly curved, stout, and about one-

fourth longer than the prothorax in the ¢, a little longer and more slender in the 9, rather closely

punctured towards the base; antenne inserted a little before the apex of the rostrum in the @,

further back in the @, joint 2 of the funiculus longer than 1(¢), or 1 and 2 subequal in length (2 ).

HILIPUS. 47

Prothorax broader than long, moderately rounded at the sides, considerably narrowed in front, bisinuate

at the base, sparsely granulate. Elytra one-half wider than the prothorax, subparallel towards the base,

conjointly rounded at the apex, the humeri rounded; seriate-punctate, the interstices transversely wrinkled

and also granulate. Ventral segment 1 in the ¢ shallowly grooved down the middle, and with a dense

oblong patch of ochreous and white scales on each side of the depression; in the Q sometimes

depressed along the middle behind. Tibise mucronate in the 9, obsoletely so in the ¢,

Length 94-12, breadth 33-5 millim. (¢ 2.)

Hab. Panama, Volcan de Chiriqui 2000 to 4000 feet, Bugaba (Champion).

Eleven specimens. Not unlike H. pulverulentus, but narrower and less robust, the

prothorax narrower, less rounded at the sides, and with the fulvous clothing more or

less concentrated into two broad converging vittee on the disc; the elytra less sinuate

at the base, and with a transverse black mark or fascia beyond the middle (sometimes

reduced to a small spot), and usually a spot beyond it.

75. Hilipus hyperoides, sp. n.

Oblong-ovate, shining, black, the legs and antenne in part piceous or rufo-piceous; the upper surface some-

what thickly clothed with fulvous scales, with some whitish ones intermixed, the latter concentrated into

a small patch on the disc of each elytron beyond the middle and also covering the scutellum; the under

surface and legs with scattercd, whitish, piliform scales. Head closely punctured, foveate between the

eyes, which are widely separated; rostrum moderately stout, curved—in the g about as long as the

prothorax and closely punctured throughout, in the Q a little longer, more slender, and smoother at

the tip; joints 1 and 2 of the funiculus subequal in length. Prothorax transverse, rounded at the sides,

abruptly constricted and narrowed in front, strongly bisinuate at the base ; closely granulate at the

sides, sparsely and transversely so on the dise. Elytra one-half wider than, and three times as long as,

the prothorax, sinuate at the base, subparallel in their basal half, conjointly rounded at the apex, the

humeri rounded and somewhat swollen; deeply seriate-punctate, the interstices broad, granulate on the

apical declivity, the outer ones granulate and transversely rugose. Metasternum and ventral segments

1-4 very sparsely, minutely punctate, the first segment unimpressed in both sexes, the metasternum

short, foveolate along the outer margin. Legs comparatively short, the tibie feebly mucronate.

Length 8, breadth 3? millim. (¢ 2.)

Hab. Mexico, Santecomapan in Oaxaca (Sallé); British Honpuras (Blancaneauz).

- Two rather worn specimens. ‘This species resembles H. dioculatus in general shape,

except that it is smaller and less convex, and has relatively shorter elytra. The amount

of white squamosity is variable, it being more abundant in the Mexican insect than in

the one from Honduras.

76. Hilipus sulcifer, sp. n. (Tab. IV. figg. 6, 6; 6a, terminal ventral

segments, 9 .)

Elongate-ovate, black or piceous, the antenne and legs sometimes partly rufescent; mottled above with a

somewhat dense clothing of fulvous and whitish scales, the latter often aggregated so as to form an oblique

stripe on the outer part of the elytra below the base and a common apical patch, the elytra with a spot

on the outer part of the disc beyond the middle (in some specimens large and sharply defined, in others

indistinct), an oblong one close to the suture at the apex, and sometimes several others on the apical half,

black; the under surface and legs thickly clothed with whitish and fulvous scales. Head rugosely

punctured and not or feebly foveate between the eyes, which are rather narrowly separated; rostrum

in the ¢ stout, feebly curved, as long as or longer than the prothorax, rugosely punctured and obsoletely

quadricarinate towards the base, smoother at the tip, that of the 2 a little longer and smoother, the

48 RHYNCHOPHORA.

antennal grooves in both sexes rapidly descending and closed behind; antenne inserted slightly before the

middle of the rostrum, joint 2 of the funiculus distinctly shorter than 1. Prothorax transverse, more or

less rounded at the sides, narrowed and constricted in front; coarsely or finely granulate, and with a short,

conspicuous, median carina at the middle. Elytra moderately long, one-half wider than the prothorax,

subparallel in their basal half, conjointly rounded at the apex, flattened on the disc, with the third

interstice often more or less costate, the humeri rounded; seriate-punctate, the interstices granulate and

usually transversely rugose. Metasternum long, foveolate at the sides. Ventral segments somewhat

closely, finely punctate, the fifth with a sharply-defined, deep, narrow sulcus down the middle in both

sexes, the first furnished with two backwardly-projecting matted tufts of fulvous piliform scales at the

middle behind in the ¢.

Length 63-9, breadth 24-34 millim.

Hab. Mexico (Sallé), Ventanas in Durango (Forrer), Jalapa, Cordova (Hége);

GuatTeMaLA, Chacoj, Teleman, Mirandilla, Cerro Zunil (Champion); Nicaragua,

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

The twenty-one specimens referred to this species agree in baving the fifth ventral

segment sulcate down the middle and the second joint of the funiculus shorter than

the first; but there is great variation amongst them in the sculpture and coloration

of the prothorax and elytra (the smoothest specimens having the prothorax straighter

at the base and less rounded at the sides), and in the relative length and sculpture of

the rostrum. The extreme forms were obtained with the more typical ones at several

localities, and there can be little doubt that they all belong to one variable species.

H. sulcifer resembles H. trinotatus in general facies, except that it is much smaller.

77. Hilipus penicillatus, sp. n. (Tab. IV. figg. 7, 2; 7a, part of under

surface, 3.)

_Oblong-ovate, black or piceous, the legs and antennze sometimes partly rufescent; thickly clothed with small,

rounded, greyish-brown scales, the prothorax with intermixed piliform scales, the elytra more or less

mottled with ochreous or whitish towards the apex, and each with a transverse or A -shaped velvety-black

mark on the disc beyond the middle, and a short black streak or triangular mark near the suture before

the apex, the scales on the scutellum whitish ; the under surface and legs thickly clothed with ochreous

or whitish scales, those on the pleura mostly rounded, the others piliform. Head rugosely punctate,

shallowly foveate between the eyes, the latter somewhat narrowly separated ; rostrum in the ¢ very stout,

moderately curved, not longer than the prothorax, rugosely punctured and tri- or quadricarinate at the

base, in the 2 a little longer and smoother, the antennal grooves descending to the lower angle of the eye

and closed behind ; antenne inserted near the apex of the rostrumin the ¢, further back in the @, joints

1 and 2 of the funiculus subequal in length. Prothorax transverse, convex, moderately rounded at the

sides, constricted and narrowed in front, feebly bisinuate at the base ; rather coarsely granulate, without

trace of median carina. Elytra one-half wider than, and three times the length of, the prothorax, parallel.

in their basal half, subtruncate at the base, conjointly rounded at the apex, the humeri rounded and rather

prominent ; seriate-punctate, the interstices transversely wrinkled, the third interruptedly costate, and all

of them with smooth scattered granular elevations, each bearing a long decumbent seta. Metasternum

and venter very minutely punctate, with scattered coarse punctures, these being deeply impressed on the

second ventral segment; first ventral segment broadly produced in the middle behind in both sexes, and

with two matted tufts of ochreous piliform scales in the middle at the apex in the ¢.

Length 5-74, breadth 24-31 millim. (¢ 9.) .

Hab. GuateMaLa, San Juan in Vera Paz (Champion); Panama, Bugaba, Volcan de

Chiriqui (Champion).

HILIPUS. 49

Fourteen specimens, one only being from Guatemala. This species, except that it

is very much smaller, has the same general shape and coloration as H. angulosus, in

which the apex of the first ventral segment is slightly produced in the centre behind.

In the setigerous elytra it resembles H. asperatus, &c.

The following species is unknown to me. It may belong to Hilipinus.

78. Hilipus tugusti.

Heilipus tugusti, Boh. in Schénh. Gen. Cure. vii. 2, p. 45°,

Hab. Mexico (coll. Chevrolat').

I am unable to certainly identify this species amongst our material, and the type of

it cannot be found in the Chevrolat collection at Stockholm. It is described as nigro-

piceous in colour, variegated above with yellowish piliform scales, the elytra with a

large, transverse, fulvous patch far beyond the middle. The prothorax broader than

long, rounded at the sides, closely granulate throughout, and with rather prominent

ocular lobes. The elytra one-half broader than, and nearly three times as long as, the

prothorax, with the sides straight to beyond the middle, and then convergent to the

apex, which is rounded; rather deeply and closely seriate-punctate, with the interstices

narrow, subconvex, and transversely rugose. |

In my remarks under J. belti (antea, p. 15) mention is made of a nearly allied form

with a peculiarly shaped prothorax: a second specimen of this insect has since come

to hand, and a description of it is therefore appended :—

14 (a). Hilipus compressicollis, sp.n. (Tab. IV. fig. 8, ¢.)

Oblong-ovate, shining, black, a broad space extending across the entire disc of the prothorax and the incrassate

portion of the femora rufous; the elytra with numerous, irregular, whitish, transverse spots and markings,

the latter tending to form two common angulated fascie, one before, the other beyond the middle. Head

foveate between the eyes; rostrum stout, curved, about as long as the prothorax, sparsely punctate

towards the base. Prothorax broader than long, rounded at the sides, sinuously narrowed behind and

constricted and much narrowed in front, the disc broadly and obliquely depressed on each side before the

middle (the depression extending inward from the lateral constriction), the base very strongly bisinuate,

the surface sparsely, irregularly punctate. lytra one-half wider than the prothorax, subparallel towards

the base, seriate-punctate, the interstices faintly transversely wrinkled. Venter with a broad depression

extending down the middle of segments 1 and 2.

ARNITICUS.

Arniticus, Pascoe, Trans. Ent. Soc. Lond. 1881, p. 96.

Parameleus, Faust, Stett. ent. Zeit. 1892, p. 33.

In the species referred to this genus the anterior opening of the scrobes is visible

from above, the scrobes. themselves extending forwards at the base of the rostrum

beneath, so as to receive the first joint of the funiculus, being, in fact, W-shaped in

both sexes. The antenne are inserted near the apex of the rostrum in both male and

female. The tibie are more or less distinctly mucronate at the inner apical angle (at

least in the females), the claw arising from about the middle of the apical margin in

the female, and from at or near the inner angle in the male.

Arniticus includes several South-American forms described by Pascoe and Faust, as

well as Hilipus lituratus and H. perturbatus, Boh., H. arrogans, Pasc., and others.

Two are now added from within our limits.

1. Arniticus cingulatus, sp. n. (Tab. IV. figg. 9, ¢; 9a, profile of head

and rostrum; 9 4, front tibia, ¢ ; 10, front tibia, 2 .)

Oblong-ovate, black or piceous, the upper surface variegated with ochreous, whitish, and black scales, the

whitish scales forming two narrow, sinuous, oblique vitte on the prothorax, a triangular spot on the

scutellum, and an irregular humeral patch and a broad curved, transverse, ante-apical fascia on the

elytra; the under surface and legs with scattered ochreous or whitish scales. Head rugose, feebly

foveate between the eyes, which are rather narrowly separated ; rostrum about one-third longer than the

prothorax, stout, moderately curved, rugose almost to the tip; joint 2 of the funiculus twice as long as 1.

Prothorax transverse, rounded at the sides anteriorly, slightly constricted before the apex and subparallel

behind ; rather sparsely granulate, and with a sharply-defined incomplete median carina. Llytra about

one-half wider than the prothorax, subparallel in their basal half, conjointly rounded at the apex, the

sutural angles somewhat pointed, the humeri rounded externally and truncate in front; deeply seriate-

punctate, the interstices more or less convex, each with a somewhat closely placed series of setigerous

granular elevations. Venter broadly depressed down the middle towards the base in the gd. Tibi

with the claw arising from the inner angle in the ¢, mucronate in the 2.

Length 10-134, breadth 4-6 millim. (¢ 2.)

Hab. Guatemata, El Tumbador, Cerro Zunil, San Isidro, Panajachel, Mirandilla

(Champion) ; Panama, Volcan de Chiriqui, Caldera (Champion).

Found in abundance at Cerro Zunil and sparingly elsewhere, all the localities being

on the Pacific slope. The coloration is somewhat variable, four of the specimens

(from Panajachel, Mirandilla, San Isidro, and Chiriqui respectively) having the light

markings pale ochreous, instead of white. A. cingulatus is extremely like the

Colombian A. lituratus (Boh.), but that insect has a much broader prothorax, and the

elytral setee shorter and less conspicuous. |

2. Arniticus setiger, sp.n. (Tab. IV. fig. 11, 2.)

Oblong-ovate, nigro-piceous, the upper surface variegated with ochreous, whitish, and black scales, the whitish

scales forming a triangular spot on the scutellum, a small spot at the base of the fifth interstice of the

elytra, and a narrow, curved, transverse, more or less distinct fascia on the disc of the latter beyond the

middle ; the under surface and legs clothed with ochreous scales. Head rugose, feebly foveate between

‘Var.? The curved whitish fascia on each elytron reduced to a small spot on the middle of the disc, the

interstitial granules larger and fewer in number. (<d.)

Hab. Nicaracua, Chontales (Belt). _

Seven examples of the typical form, and two of the variety, which should perhaps

be treated as a separate species. Very like A. cingulatus, but less elongate, the

prothorax more rounded at the sides and without distinct vitte, the elytra with fewer

granular elevations in the interstitial series and these bearing longer and stouter sete.

From A. perturbatus (Boh.) it differs in having a more distinctly carinate prothorax and

longer elytral sete.

HILIPINUS, gen. nov.

Scrobes partly visible from above, open and extending forward on the inner side beneath, in the ¢ reaching

to at least the middle of the rostrum, and receiving the whole or part of the funiculus, and sometimes the

club also, in the @ receiving the basal joint only of the funiculus. Tibial claw arising from: the inner

apical angle of the tibia in the d, and from near the middle of the apical margin in the Q, the inner apical

angle mucronate in the 2. Tibie usually more or less sulcate on their outer edge, and the rostrum

also on either side above. The other characters as in Hilipus.

This group of species, the characters of which were in part noticed by Lacordaire

(Gen. Col. vi. p. 457, nota 4), includes Heilipus ascius and I. cadivus, Germ.,

H. ziegleri, Boh., H. mortuus, Thoms., H. occultus and H. tetraspilotus, Pasc., and

others. ‘The males are easily distinguishable from those of the allied genera by the

extended antennal grooves on the underside of the rostrum; the females, however,

have these grooves \/-shaped, as in both sexes of Arniticus, from which genus they

sulcate tibia. The antenne are inserted in both sexes near the apex of the rostrum.

The humeri in many of the species are angular in front. The rostrum in the male has

two prominences at the base beneath, these sometimes forming sharp teeth. The

tibiee are deeply sulcate in many of the species, and shallowly so in others, the sulci,

however, are occasionally absent; their apical armature is similar to that of the species

and rostrum; 12, rostrum from beneath.)

Elongate, broad, robust, black, variegated above with minute fulvous scales, with still smaller scales intermixed ;

the under surface and legs also clothed with fulvous scales, those on the pleura and the sides of the

venter coarser than the rest. Head densely, rugulosely punctured, not foveate between the eyes, which

are somewhat widely separated; rostrum very stout, broad, feebly curved, a little longer than the

prothorax, rugulosely punctured to the tip and indefinitely tricarinate, laterally sulcate, the scrobes in

great part visible from above and forming deep sinuous furrows beneath for the reception of the funiculus

and club ; joint 2 of the funiculus considerably longer than 1. Prothorax transverse, feebly bisinuate at

the base and deeply emarginate at the apex, the sides almost straight behind and arcuate and converging

anteriorly, strongly constricted in front; the surface densely, very minutely punctate and also very finely

granulate, with an interrupted median carina. Elytra one-fifth wider than, and three and one-half times

as long as, the prothorax, moderately convex to the middle and flattened on the disc thence to the apex,

the sides subparallel to beyond the basal half, the apices a little produced at the sutural angle, the

humeri rounded externally and truncate in front; shallowly and rather finely seriate-punctate, the

interstices broad, densely rugulose, and minutely granulate. Venter closely, finely punctate, the first

and second segments very broadly depressed down the middle. Tibiz shallowly sulcate.

Length 214, breadth 9 millim. (<¢.)

Hab. Guatemata, Chacoj in the Polochic Valley (Champion).

One specimen. This species, which is more elongate in form than the allied

H. ascius and H. biguttatus, is remarkable from the fact of having the rostrum

sufficiently sulcate beneath to receive the entire antenna in repose, the sulci curving

outwards towards the apex of the rostrum and widely separated at its base. H. corruptor

(Boh.), from Brazil, is very like H. ingens, but the rostrum in the male of the latter 1 is

not nearly so stout, and has the funicular grooves parallel.

2. Hilipinus biguttatus, sp.n. (Tab. IV. fig. 18, ¢.)

Oblong-ovate, robust, subopaque, black, densely clothed with narrow, minute, intermixed fulvous and cinereou

scales, each elytron with a very large, velvety, brownish-black lateral patch a little beyond the middle,

the prothorax with indications of an oblique line of pallid scales on either side of the disc; the under

surface and legs with scattered ochreous or whitish piliform scales, the tip of the abdomen, the apices of

the tibize, and the soles of the tarsi with fulvous hairs. Head rugulosely punctured, not foveate between

the eyes, which are widely separated ; rostrum very stout, broad, feebly curved, slightly longer than the

prothorax, rugosely punctured and tricarinate, smoother at the tip, sulcate laterally, the scrobes in

Hab. Panama, Chiriqui (coll. Godman & Salvin).

One specimen. A close ally of the Brazilian H/. ascius (Germ.), differing from that

species in its broader form, the presence of a very large, lateral, brownish-black, velvety

patch on each elytron, and the broader and deeper sulci on the underside of the rostrum

in the male.

3. Hilipinus laticollis, sp.n. (Tab. IV. fig. 14, 2.)

Oblong, robust, slightly shining, black or piceous; thickly clothed with minute scales, which are mostly

fulvous in colour, the elytra with a common, indeterminate, transverse, blackish-brown fascia at about

the middle followed by a whitish one, and also with a few scattered whitish scales, the scutellum clothed

with whitish scales; the under surface and legs with fulvous piliform scales. Head densely rugose, not

foveate, the eyes rather widely separated; rostrum (3) broad, very stout, a little longer than the

prothorax, longitudinally rugose and also carinate, laterally suleate, the antennal grooves in great part

visible from above, (@) a little longer, narrower, and much smoother towards the tip; joint 2 of the

funiculus nearly twice as long as 1. Prothorax transverse, broad, deeply emarginate at the apex, feebly

pisinuate at the base, the sides rounded anteriorly, almost straight behind, and constricted in front ;

and three times the length of, the prothorax, moderately convex, subparallel in their basal half, conjointly

rounded and considerably produced at the apex, with the sutural angle slightly dentiform, the humeri

- rounded externally and truncate in front; closely seriate-punctate, the interstices somewhat convex, trans-

versely rugulose, and very finely granulate. Venter sparsely punctate, the first and second segments

Hab. Ntcaraeua, Chontales (Belt).

Two males and two females. Smaller and less elongate than H. ingens, and more

oblong than Hi. biguttatus and H. ascius, and differing from all three in the maculation

of the elytra, these having an irregular, common, dark fascia at about the middle

followed by a whitish one. The prothorax is very broad, as in H. ingens, but less

broader form.

4, Hilipinus alternatus, sp. n.

Oblong-ovate, slightly shining, black; the head and prothorax variegated with small fulvous scales, the

scutellum clothed with whitish ones; the elytra thickly clothed with fulvous scales, and each with a

subquadrate brownish-black spot about the middle of the disc and a smaller subtriangular one near the

apex, the stria with alternate brownish-black and whitish spots, the base with a fulvous spot near the

shoulder; the under surface and legs clothed with fulvous and whitish scales. Head densely, rugosely

punctate, not foveate, the eyes rather widely separated ; rostrum stout, a little longer than the prothorax,

sparsely, minutely punctate, with coarser punctures intermixed, the first segment depressed down the

middle behind.

Length 114, breadth 51 millim. (Q.)

Hab. Guatemata, Torola (Champion).

One specimen, from the “tierra caliente” of the Pacific slope, evidently a female

(to judge from the form of the rostrum), though it has a depression on the first ventral

segment. This species isa close ally of H. laticollis, but is much smaller, and has

less elongate and very differently marked elytra, each of the strie being maculated

with small whitish spots alternating with oblong brownish-black ones, there being also

a conspicuous subquadrate blackish spot on the middle of the disc. From similarly-

coloured varieties of H. punctatoscabratus the broader form and: more robust build, and:

the less rugose elytral interstices, sufficiently distinguish it.

angle. The rostrum is stout, rugose, and more or less carinate in the male, smoother

and more slender in the female. The upper surface is more or less variegated with

fulvous, whitish or greyish, and brown scales, and there is always a line of pallid scales

on each side of the base of the prothorax, a similarly-coloured patch on the scutellum,

and another at the base of the elytra near the shoulder, each elytron often having a

large irregular black patch (particularly noticeable in immature specimens, but not

visible in the type) on the middle of the disc: specimens thus marked are labelled

H. biplagiatus, Chevr., in the Sallé collection. The males have a broad depression

down the middle of the first or first and second ventral segments. In some specimens

the tibiz are faintly sulcate. ‘The species varies greatly in size, from 7-12 millim. in

length and 3-5 millim. in breadth. A female of large size from Purula, Guatemala,

has the elytra very much broader than the prothorax, with a sharply defined black

patch on the disc of each, and the sutural angles produced into a long tooth; it may

belong to a different species. A pair from Capetillo are very small and narrow, and

these also may have to be separated.

6. Hilipinus mucronatus, sp. n.

Oblong-ovate, moderately broad, black, the femora and tibie in part obscurely rufescent ; somewhat thickly

clothed with minute fuscous scales, the prothorax with a very small ochreous spot at the base on each side,

the elytra with a large rounded velvety-black patch on the disc beyond the middle, followed by two or

three small ochreous spots, and aiso with a few other scattered similar spots ; the legs and under surface

with scattered, minute, fulvous, piliform scales. Head rugosely punctate, faintly foveate between the

eyes ; rostrum moderately stout, feebly curved, much longer than the prothorax, sulcate laterally, closely,

finely punctate, the punctuation becoming rugose towards the base. Prothorax strongly transverse,

rounded at the sides, and narrowing from a little before the base to the apex, constricted in front, the

base almost straight; the surface closely and somewhat coarsely granulate, with an abbreviated median

carina. Elytra about one-half wider, and three and one-third times longer, than the prothorax, sub-

parallel in their basal half, the apices broadly produced and conjointly rounded, each furnished with a

rather long blunt tooth near the sutural angle, the humeri rounded ; seriate-punctate, the interstices.

densely rugulose and granulate throughout. Legs elongate. First ventral segment depressed in the

middle.

Hab. Mexico, Colonia (Lohr).

One specimen. Nearly allied to H. punctatoscabratus, but larger and with a much

longer rostrum than in the female of that species ; the elytra separately mucronate at

the apex, and with a large, rounded, velvety-black patch on the dise followed by two

or three small ochreous spots.

7. Hilipinus scabiosus, sp. n. (Tab. IV. fig. 16, ¢ .)

Oblong-ovate, broad, moderately shining, black, the antenna piceous ; the base of the rostrum, the prethorax,

scutellum, and elytra clothed with scattered ochreous scales, which tend to form longitudinal streaks on

the disc of the latter towards the apex, where they are intermixed with some white ones, the rest of the

upper surface clothed with minute fuscous scales ; the legs and under surface thickly, and the middle of

the metasternum and the venter sparsely, clothed with ochreous scales. Head rugosely punctured, not

funiculus nearly twice as long as 1. Prothorax transverse, much narrowed in front and slightly so

behind, the sides rounded ; coarsely and closely granulate throughout, with an incomplete median carina.

Elytra about one-third wider than the prothorax, comparatively short, subparallel in their basal half,

conjointly rounded at the apex, the humeri rounded externally and truncate in front; very coarsely

Legs short and stout, the tibie feebly mucronate.

Length 11, breadth 5 millim. (@.)

Hab. Panama, Bugaba (Champion).

One specimen. Recognizable by its short broad form, peculiar coloration, closely

granulate prothorax, and densely squamose legs.

8. Hilipinus fusiformis, sp. n.

Subfusiform, fmoderately shining, piceous, the head, rostrum, and legs more or less rufescent ; the upper

surface (? abraded) with a few scattered ochreous scales, which are aggregated into an oblique line on

each side of the prothorax and two minute spots on the outer part of the disc of each elytron (one at one-

third from the base, and the other at one-third from the apex); the under surface with scattered whitish

and ochreous scales, the ventral surface and legs with whitish piliform scales. Head densely punctate,

shallowly impressed between the eyes, which are somewhat widely separated ; rostrum (¢) broad and

stout, curved towards the tip, slightly longer than the prothorax, densely, rugosely punctate from the

base to the apex, conspicuously carinate down the middle, and sulcate at the sides, the grooves beneath

separated at the base by two flattened dentiform prominences ; joints 1 and 2 of the funiculus equal in

length. Prothorax transverse, subconical, closely granulate, the elevations here and there obliquely

confluent on the disc, and with an abbreviated median carina. Elytra convex, rather more than three

times the length of, and about one-third wider than, the prothorax, considerably produced at the apex,

gradually narrowing from the base, the humeri truncate in front and rounded externally, the subapical

callosities not prominent ; coarsely and closely seriate-punctate, the interstices smooth and narrow, and

on the apical declivity finely granulate. Ventral segments ( 3) 1-5 sparsely, minutely punctate, 1 and 2

with a broad depression down the middle, and 5 depressed on each side. ‘Tibie deeply sulcate on their

outer edge.

Length 104, breadth 44 millim. (¢.)

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

One specimen. In the sulcate tibie and the grooving of the underside of: the

rostrum this species agrees with H. sulcirostris and H. sulcicrus, from which it differs

in the conical prothorax, the shorter second joint of the funiculus, and the obtuse

humeri, the elytra themselves being more convex and gradually narrowing from the

base. Viewed in profile, the rostrum is sinuous on its lower edge, this being due to

the funicular grooves extending outwards towards the apex.

9. Hilipinus quadrimaculatus, sp.n. (Tab. IV. fig. 17, ¢.)

Oblong-ovate, slightly shining, piceous or rufous; the prothorax with an oblique vitta on each side, and the

elytra with a rounded or transverse patch at the sides below the shoulders and a rather broad transverse

fascia on the disc some distance before the apex, whitish or pale ochreous; the rest of the upper surface

clothed with minute scattered ochreous scales; the under surface and legs with scattered narrow white

scales, the cilia at the outer apical angles of the four hinder tibiee blackish. Head densely punctured,

without distinct fovea between the eyes, which are somewhat widely separated; rostrum a little longer

grooves in the ¢ extending sinuously forwards beneath ; joint 1 of the funiculus slightly shorter than 2.

Prothorax broader than long, rounded at the sides, considerably narrowed in front and slightly so behind ;

granulate, and sometimes with an abbreviated median carina, Elytra moderately long, a little flattened

on the disc, subparallel at the base, about one-third wider than the prothorax, the humeri rounded

externally and subangular in front, the apices somewhat produced and with the sutural angle pointed ;

yery coarsely seriate-punctate, the interstices narrow and more or less granulate. Tibie more or less

sulcate along their outer edge. First ventral segment sulcate down the middle in the male.

Hab. Guatremata, El Tumbador and Cerro Zunil, 4000 to 5000 feet (Champion).

Found in plenty on the Pacific slope. A close ally of H. integellus (Boh.), but with

very different and much more definite whitish markings, these consisting of two sharply-

limited spots or fascie on each elytron and a submarginal vitta on either side of the

prothorax. .

10. Hilipinus humeralis, sp.n. (Tab. IV. fig. 18, ¢ .)

Oblong-ovate, subopaque, piceous or rufo-piceous ; the prothorax with an oblique vitta on each side, and the

elytra with a small spot at the shoulder and a large triangular one below it (the two often coalescent

and forming a short curved stripe), as well as a broad transverse fascia on the disc some distance before

the apex, whitish or pale ochreous ; the rest of the upper surface clothed with minute scattered ochreous

scales ; the under surface and legs with scattered, narrow, white scales, the cilia at the apex of the four

hinder tibia ochreous. Head closely punctured, not or obsoletely foveate between the eyes, which are

somewhat widely separated ; rostrum about one-third longer than the prothorax, curved, very stout,

rugosely punctured, except at the tip, suleate laterally; joint 1 of the funiculus slightly shorter than 2.

Prothorax much broader than long, rounded at the sides, narrowed and constricted in front and slightly

narrowed behind; granulate, and with a smooth median carina. Elytra moderately long, subparallel at

the base, about one-third wider than the prothorax, the humeri rounded externally and subangular in

front, the apices somewhat produced and with the sutural angle pointed; very coarsely seriate-punctate,

the interstices granulate. First ventral segment sulcate down the middle in the male. Tibis obsoletely

sulcate on their outer edge.

Length 84-114, breadth 33-5 millim. (¢ 2.)

Hab. Guatemata, Cerro Zunil, Purula (Champion).

Found in numbers at Cerro Zunil with H. quadrimaculatus, of which at first sight it

would appear to be nothing more than a varietal form; apart, however, from the

additional humeral spot, which is often confluent with the second one, the prothorax is

more transverse, and the subapical fascia on the elytra is much broader, forming a large

transverse-oval patch on the middle of the disc.

tibiee (a character overlooked by Boheman), and the anteriorly prominent humeri.

The prothorax is transverse, rounded at the sides, constricted in front, granulate, with

a median carina and two irregular, narrow, sinuous, evanescent, ochreous vitte. The

elytra are considerably produced at the apex, coarsely seriate-punctate, with the

interstices granulate; the markings are sordid-ochreous in colour, and chiefly consist

of a large irregular patch on the outer part of the disc before the middle, from which

a branch extends forward to the base, a large angulated or cruciform patch on the disc

before the apex, and, sometimes, an apical spot. The first ventral segment is deeply

depressed down the middle in the male, and the fifth very coarsely punctured. ‘The

head is rugosely punctured, not foveate between the eyes, which are rather narrowly

separated. The rostrum in the male is about as long as the prothorax, very stout,

densely, rugosely punctured, and towards the base carinate and laterally sulcate, the

antennal grooves extending far forward along the middle beneath, and forming deep

sulci for the reception of the funiculus.

12. Hilipinus sulcicrus, sp.n. (Tab. IV. fig. 20, ¢.)

Oblong-ovate, slightly shining; piceous or rufo-piceous, the prothorax with a broad curved vitta on each side,

the elytra with a very broad, irregular, sinuous, more or less interrupted, band extending from just within

the humeri to the suture a little before the apex, and the head with a few scales between the eyes, white

or whitish ; the rest of the upper surface with minute ochreous scales, the under surface and legs with

narrow white scales, Head closely punctured, not or obsoletely foveate between the eyes, which are

rather narrowly separated; rostrum very stout, curved, a little longer than the prothorax, rugosely

punctured almost to the tip, carinate along the middle and shallowly sulcate at the sides ; joint 1 of the

funiculus slightly shorter than 2. Prothorax strongly transverse, rounded at the sides, narrowed and

constricted in front, and slightly narrowed behind; closely granulate, and with an incomplete median

carina. Elytra rather short, about one-fourth wider than the prothorax, subparallel below the base, the

humeri rounded externally and angular in front, the apices conjointly rounded ; coarsely seriate-punctate,

the interstices granulate. Ventral segments 1—4 almost smooth, 5 coarsely punctured, 1 depressed down

the middle behind in the male. Tibiz sulcate on their outer edge.

Length 74-9, breadth 3? millim. (d¢ 2.)

Hab. Panama, Bugaba (Champion).

Three specimens. Very like ZH. integellus, but easily distinguishable therefrom by

the broad white prothoracic vitte (the space occupied by these being free from

granules), which are continued as an irregular more or Jess interrupted band down the

elytra to the suture before the apex, the latter also less produced. The general

coloration is very like that of Hilipus cruciatus and its allies.

13. Hilipinus sulcirostris, sp.n. (Tab. IV. fig. 21, 2.)

Oblong-ovate, subopaque, nigro-piceous; the prothorax with a sinuous, oblique, pure white vitta on each

side, which becomes very narrow in front; the elytra with an irregular curved stripe on the outer part

of the disc extending down the basal third, and an interrupted cruciform patch on the disc some distance

before the apex, also white ; the rest of the upper surface clothed with minute ochreous scales, which on

the elytra are intermixed with fuscous ones, so as to form small spots; the under surface and legs with

narrow white scales. Head densely, rugosely punctured, not foveate between the eyes, which are rather

narrowly separated; rostrum exceedingly stout, curved, a little longer than the prothorax, densely,

rugosely punctured almost to the tip, obsoletely carinate, sulcate laterally, the antennal grooves extending

far forward along the middle beneath, forming broad, deep, sinuous sulci; joint 1 of the funiculus slightly

shorter than 2. Prothorax strongly transverse, rounded at the sides, much narrowed in front and slightly

so behind ; granulate, and with an incomplete median carina. Elytra about one-third wider than the

prothorax, subparallel below the base, the humeri rounded externally and subangular in front, the apices

conjointly rounded; coarsely seriate-punctate, the interstices granulate. Ventral segment 1 sulcate

down the middle. Tibiz sulcate on their outer edge.

Length 10, breadth 43 millim. (¢.)

Hab. Guatemaa (Conradt).

One specimen. Allied to H. integellus and H. sulcicrus, but with a still stouter and

more rugose rostrum, which is obsoletely carinate above and has longer, broader, and

deeper grooves beneath for the reception of the funiculus of the antenne. The

prothoracic and elytral markings resemble those of H. integellus, except that they are

pure white, and there is no trace of an apical spot; the prothorax, too, is more

transverse than in that species.

14. Hilipinus dentirostris, sp.n. (Tab. IV. figg. 22, ¢; 224, profile of

head and rostrum.)

Oblong-ovate, slightly shining, rufo-piceous, the legs rufescent, with joints 1-3 of the tarsi blackish ; the

prothorax with a very small spot on each side at the base near the hind angles, the elytra with a small

spot just within the humeri, about five others in an oblique series below this, and a somewhat cruciform

mark on the disc towards the apex, white, the rest of the upper surface clothed with minute greyish

somewhat widely separated ; rostrum very stout, curved, a little longer than the prothorax, rugose almost

to the tip, finely carinate down the middle, the antennal grooves extending far forward along the centre

beneath and separated at the base by two dentiform prominences ; joint 1 of the funiculus slightly shorter

than 2. Prothorax much broader than long, moderately rounded at the sides, constricted before the

apex, much narrowed anteriorly and slightly so at the base; finely granulate and with indications of a

raised line down the middle. Elytra moderately long, narrowing almost from the shoulders, barely one-

fourth wider than the prothorax, sinuate at the base, the humeri angular in front and rounded externally,

the apices somewhat produced and conjointly rounded; rather coarsely seriate-punctate, the interstices

transversely rugose and granulate. Venter deeply depressed along the middle. Tibi obsoletely sulcate

on their outer edge.

Length 11, breadth 43 millim. (¢.)

Hab. Nicaracua, Chontales (Belt).

One specimen. Allied to H. integellus and H. sulcirostris, but with the white

markings of the upper surface reduced to small spots, the rostrum armed with two

dentiform prominences at the base beneath, the prothorax finely granulate. The

grooves on the underside of the rostrum are broad, becoming evanescent beyond the

middle.

15. Hilipinus curvirostris, sp. n.

Elongate-ovate, narrow, shining, piceous, the antennal scape and the legs in part rufescent; above and beneath

clothed with scattered, coarse, oblong, ochreous and whitish scales; the legs with whitish piliform scales.

60 RITYNCHOPHORA.

Head densely punctate, foveate between the eyes, which are somewhat widely separated; rostrum

stout, strongly curved, about as long as the head and prothorax, for two-thirds of its length densely

rugosely punctate, and also carinate and laterally sulcate, the apical third minutely punctate and more

shining, the antennal grooves extending shallowly forwards along the middle beneath ; joint 2 of the

funiculus much longer than 1. Prothorax strongly transverse, convex, rounded at the sides, abruptly

constricted and much narrowed in front, moderately bisinuate at the base; closely and rather coarsely

granulate, carinate along the middle towards the apex. Elytra convex, a little wider than, and three

times as long as, the prothorax, subparallel in their basal half, the base subtruncate, the humeri

obtuse, the apices considerably produced and conjointly rounded, the subapical callosities not prominent ;

coarsely and deeply seriate-punctate, the interstices smooth, rather convex, about the same width as

the punctures, feebly, transversely wrinkled, and also very faintly granulate. Ventral segments sparsely

and finely, the apex of the fifth coarsely, punctate, the first depressed along the middle. Tibize sulcate

on their outer edge.

Length 84, breadth 3} millim. (<d.)

Hab. Panama, Volcan de Chiriqui (Champion).

One specimen, apparently somewhat abraded, the scales on the elytra not forming

definite markings. This insect agrees with H. imtegellus in having grooves on the

underside of the rostrum (except that they are shallower), as well as in the sulcate

tibie; but it differs from that species and other allied forms in the short convex

prothorax, the strongly curved rostrum, the subtruncate base of the elytra, the obtuse

humeri, &c. The second joint of the funiculus, as in H. integellus, H. sulcicrus,

and H. sulcirostris, is much longer than the first. ‘The coarsely granulate prothorax,

the less elongate, posteriorly narrowed elytra, &c., separate AH. curvirostris from

H. punctatoscabratus.

16. Hilipinus occultus. (Tab. IV. fig. 23, 2.)

Hilipus occultus, Pasc. Trans. Ent. Soc. Lond. 1881, p. 90°.

Hab. Nicaragua, Chontales! (Belt); Costa Rica (Mus. Brit.); Panama, Bugaba

(Champion).

This insect is extremely like H. integellus, but it is smaller and less robust, the

second joint of the funiculus is relatively longer (not, however, more than twice as

long as the first, as stated by Pascoe), and the antennal grooves on the underside of

the rostrum are shallower. Of the five specimens before me, one only is of the

male sex.

17. Hilipinus guatemalensis, sp. n.

Oblong-ovate, slightly shining, piceous ; the elytra with a large irregular patch on the outer part of the disc

before the middle, from which a branch extends forward to the base, a large somewhat cruciform patch

on the disc at about one-third from the apex, and an apical spot, obscure ferruginous ; the prothorax

with an indefinite sinuous vitta on each side, formed by scattered fulvous scales, the elytral markings also

clothed with fulvous scales, and sometimes bordered with a few ochreous or whitish ones, the rest of the

sparse squamosity of the upper surface obscurely coloured; the under surface and legs with widely

scattered, piliform, whitish scales. Head rugosely punctured, obsoletely foveate between the eyes, which

HILIPINUS.—TELYS. 61

are somewhat widely separated ; rostrum moderately stout, curved, a little longer than the prothorax,

densely, rugosely punctate, carinate, and laterally sulcate, smoother at the tip, in the Q less densely

punctate, and much smoother in its apical half; joint 2 of the funiculus nearly twice as long as 1.

Prothorax transverse, rounded at the sides, constricted and much narrowed in front and slightly narrowed

behind, strongly bisinuate at the base; the surface somewhat closely granulate, a narrow space along the

middle and a sinuous one on either side excepted, and with an abbreviated median carina, Elytra convex,

about one-third wider than the prothorax, considerably produced at the apex, subparallel at the base, the

humeri somewhat angular in front, the apices slightly prominent at the sutural angle; coarsely seriate-

punctate, and finely granulate, the interstices transversely rugulose. Venter and metasternum almost

smooth, the first ventral segment depressed down the middle in the male. Tibia obsoletely sulcate or a

little flattened on their outer edge.

Length 9-11, breadth 33-42 millim. (3 2.)

Hab. Guatemaa, Cerro Zunil, Senahu, Sinanja (Champion).

Six specimens, all more or less abraded. ‘This insect is extremely like H. integellus

and H. occultus, the general coloration of the elytra being similar; but the tibiz

are less distinctly sulcate, and the humeri are not so angular in front. The second

joint of the funiculus is elongate, as in H. occultus, and the grooves on the underside

of the male rostrum are formed as in that species, these being shallower than in the

same sex of HH. integellus, in which they are separated by an acute ridge.

18. Hilipinus ochreopictus, sp.n. (Tab. IV. fig. 24, 2 :)

Oblong-ovate, shining, the head and prothorax duller, black or piceous ; the prothorax with a small spot on

each side at the base, and the elytra with one at the shoulder, several others below this, and about six

clustered together on the disc at some distance before the apex (in one specimen united into a cruciform

patch), ochreous; the rest of the upper surface clothed with minute fuscous scales; the under surface and

legs with scattered, narrow, white scales, the propleura with an ochreous spot before the anterior coxe.

Head thickly punctured, feebly foveate between the narrowly separated eyes; rostrum a little longer than

the prothorax, stout, curved, rugosely punctured, obsoletely carinate towards the base, and sulcate

laterally in the ¢, smoother in the 2, the antennal grooves in the male extending shallowly forwards

beneath for the reception of the basal joints of the funiculus; joint 1 of the funiculus slightly shorter

than 2. Prothorax broader than long, much narrowed in front, the sides rounded anteriorly and almost

straight behind; finely and rather sparsely umbilicate-punctate, and with a more or less distinct smooth

median line. Elytra about one-fourth wider than the prothorax, subparallel below the base, conjointly

rounded at the apex, the humeri angular in front; coarsely seriate-punctate, the interstices flat and each

with a single series of minute granules, which become evanescent on the disc before the base. Ventral

segment 1 depressed down the middle in the male, 5 coarsely punctured. Tibiz more or less sulcate.

Length 9-11, breadth 34-44 millim. (¢ 2.)

Hab. Nicaragua, Chontales (Belt, Janson).

One male and three females. This species somewhat resembles Hilipus trifasciatus

in general coloration, but is really allied to Hilipinus integellus, the antennal grooves

in the male extending forwards on the underside of the rostrum for the reception of the

basal joints of the funiculus, the tibie are sulcate, and the humeri are angular in front.

TELYS, gen. nov.

Antenne inserted near the tip of the rostrum in the ¢, and at about one-third from the apex in the 9;

funiculus 7-jointed, joint 1 much stouter than 2; rostrum much curved and nearly equal in thickness in the

62 RHYNCHOPHORA.

two sexes, the scrobes descending to the lower front margin of the eye, the anterior opening only visible

from above ; eyes lateral, transverse, separated by a space equalling the width of the rostrum ; prothorax

broadly and shallowly arcuato-emarginate at the apex beneath; scutellum transverse, minute ; elytra

acutely margined at the base; femora moderately clavate and acutely toothed ; tibie curved, sinuous

within, the claw arising from near the inner apical angle ; anterior coxee contiguous, the intermediate pair

narrowly, the posterior pair very widely, separated ; metasternum shorter than the first or second ventral

segments ; form narrow, elongate, in profile bisinuate.

The single species referred to this genus cannot very well be included in Hilipus,

even in its extended sense, the scutellum being very minute and the basal margin of

the elytra acutely raised. When the prothorax and elytra are closely fitted together

and the rostrum is in its normal position, the general profile of the insect is )-shaped,

this being partly due to the transversely depressed anterior portion of the elytra. From

Lixomorpha, which also has a small scutellum and the basal margin of the elytra raised

at the middle, it may be distinguished by the very similarly formed rostrum in the two

sexes, the shorter metasternum, the relatively shorter tarsi, &c.; and from Epistrophus,

a genus including a single species from Colombia, by the transverse eyes (these being

large, rounded, and somewhat depressed in Hpistrophus), the minute scutellum, the

shorter metasternum, &c.

1. Telys bisinuatus, sp.n. (Tab. IV. figg. 25, 25a, 2.)

Elongate, narrow, moderately convex, slightly shining, black or piceous, the rostrum, antenne, and legs partly

rufescent ; above somewhat sparsely clothed with fulvous scales, and with a line of coarse, rounded,

ochreous scales running along the sides of the head and prothorax, and round the outer margin of the

elytra to a little below the humeri; the under surface sparsely squamose, the pleura with coarse rounded

pallid scales; the legs with piliform scales. Head rugulosely punctate, foveate between the somewhat

coarsely facetted eyes, smooth beneath; rostrum stout, strongly curved, in the ¢ about as long as the

prothorax, rugosely punctured to near the tip, and faintly carinate, in the Q longer and smoother ;

joints 1 and 2 of the funiculus subequal in length. Prothorax a little longer than broad, subcylindrical,

slightly narrowed in front and behind, strongly bisinuate at the base; densely, rugosely punctate, the

narrow interspaces appearing granulate. Elytra elongate, not much wider than the prothorax, flattened

on the disc and transversely depressed towards the base, somewhat abruptly narrowed at about one-fourth

from the apex, the apices conjointly rounded and produced, the humeri rounded and not prominent ; closely

seriate-punctate, the interstices narrow, transversely rugose, and finely granulate, the fourth nodose at

one-third from the base and the third at one-third from the apex, the fifth also carinate towards the

tip. Beneath coarsely punctate, the first ventral segment broadly depressed down the middle in the ¢.

Legs elongate, the femora and tibie rugose, the tarsi smooth and shining above.

Length 43-5, breadth 14-2 millim. (¢ @.)

Hab. Guatemata, Purula, Senahu, and Sinanja in Vera Paz (Champion).

Two males and two females, varying somewhat in the development of the nodiform

prominences on the third and fourth elytral interstices. The head is smooth beneath,

as in the species of the group Anchonina.

LIXOMORPHA, gen. nov.

Rostrum exceedingly stout in the ¢, much more slender in the ? ; scrobes deep, descending to the lower

anterior margin of the eye, the anterior portion visible from above ; eyes lateral, transverse, not prominent,

appearing very narrow as viewed from above; antenne inserted near the apex of the rostrum, the

LIXOMORPHA.—ANCHONOMORPHA. 63

funiculus 7-jointed, joint 2 slightly shorter than 1 inthe g and much longer than it in the 9? ; scutellum

very small, transverse as seen from above; anterior cox contiguous, the intermediate pair very narrowly

separated ; metasternum about as long as the first ventral segment, the episterna very narrow in the

Q, broader in the ¢ ; legs long and rather slender, the femora moderately clavate and armed with

a short tooth towards the apex, the tibiz sinuous and furnished at the inner apical angle with a sharp

claw, which is preceded by two matted spine-like tufts of hair, the tarsi elongate.

This genus, which includes a single species from Costa Rica *, is closely related to

Hilipus (Sect. I.), but differs from it in the small transverse scutellum, the feebly dentate

femora, the laterally placed eyes (which are separated by a space fully equalling

the width of the rostrum), &c. In general facies, Livomorpha resembles Callinotus

and Desmosomus, of the group Cholina, but in these latter the anterior and intermediate

coxee are more or less widely separated. The sexual differences in the form of the

rostrum and antenne are very remarkable. The genera Cheris, Pasc., and Hpistrophus

and Ischiomastus, Kirsch, also have the eyes similarly placed, but they are not other-

wise very nearly related to Lixomorpha.

1. Lixomorpha albomarginata, sp.n. (Tab. IV. figg. 26, 26a, 3; 27, 2.)

Elongate, subfusiform, opaque, the rostrum and under surface shining ; the head, prothorax, and elytra each

with a marginal stripe of white or pale ochreous scales, those on the head narrow and the others rounded,

the rest of the surface with widely scattered similarly coloured scales. Head shallowly foveate between

the eyes, almost smooth ; rostrum moderately curved, in the ¢ a little shorter than the prothorax,

closely punctured at the sides, smooth at the tip, carinate along the middle, and about one-half the width

of the apex of the prothorax, in the Q@ longer and smoother, cylindrical, and comparatively slender ;

joint 2 of the funiculus a little shorter than 1 in the g, and at least twice as long as it is in the Q.

Prothorax as long as broad, subconical, narrowing from a little before the base to the apex, the base

deeply bisinuate, the surface with extremely minute, scattered, shallow punctures, and with indications

of a smooth raised median line. Elytra elongate, much wider than the prothorax, narrowing almost from

the base, conjointly rounded at the apex, flattened on the inner part of the dise and obliquely sloping

towards the outer margin, the base trisinuate and with the margin raised and thickened on either side of

the scutellum ; seriate-punctate, the interstices flat and almost smooth, the third appearing a little raised,

but not callose towards the tip. Venter sparsely punctate, and in the ¢ with a broad, deep, oval

depression extending down the middle of the first and second segments.

Length 11-13, breadth 4-42 millim. (¢ @.)

Hab. Costa Rica, Rio Sucio, lrazu (Logers).

Two females from Irazu and a male from Rio Sucio, all in a rather bad state of

preservation.

ANCHONOMORPHA, gen. nov.

Antenne inserted near the apex of the rostrum, funiculus 7-jointed, joint 1 stouter than those following ;

rostrum stout, similar in form in the two sexes, the scrobes deep, visible from above in front, descending to

the lower anterior margin of the eye; eyes coarsely facetted, lateral, separated by a space fully as wide as

the rostrum, transverse, narrow and oblique as seen from above; prothorax very deeply and abruptly

arcuato-emarginate at the apex beneath, the prosternum broadly depressed along the middle; scutellum

small, oval ; elytra with series of rounded or oblong squamigerous prominences ; anterior coxze contiguous ;

* There is an undescribed species from Colombia in the British Museum, labelled Heilipus callinotoides,

Jekel, that may belong to it.

64 RHYNCHOPHORA.

first and second ventral segments connate at the middle; metasternum short; femora strongly clavate

and acutely toothed ; tibia sinuous within, the claw arising near the inner apical angle in the ¢, and

from about the middle of the apical margin in the 9, in which sex the inner apical angle is more or

less mucronate, and also furnished with two matted spine-like pencils of hair at the tip; penultimate

tarsal joint bilobed. ,

The three species referred to this genus, which will also include at least one South-

American form, are very like some of the members of the group Anchonina, from

which they may be distinguished by the more exserted, strongly punctured, and less

globose head. The very widely separated eyes, the partially connate first and second

ventral segments, and the peculiar sculpture of the upper surface separate them from

Hilipus, to which otherwise they are closely allied. The fusion of the first two ventral

segments is a character common to most of the Anchonina.

1. Anchonomorpha occulta, sp.n. (Tab. IV. figg. 28, 28a, 2.)

Oblong-ovate, dull above and shining beneath, black, the antenne and tarsi partly rufescent ; clothed above

with scattered, narrow, minute, brownish scales, these being coarser and more elongate on the elytral

elevations, the entire upper surface often coated with an earthy incrustation ; the under surface with

very few scales; the legs thickly clothed with curved setiform scales. Head densely punctate, foveate

between the eyes; rostrum stout, slightly longer than the prothorax, moderately curved, rugosely

punctured, 5-carinate ; joints 1 and 2 of the funiculus subequal in length. Prothorax a little broader

than long, rounded at the sides anteriorly, considerably narrowed in front, and slightly so behind, the

base strongly bisinuate; the surface densely, rugosely punctured, somewhat uneven towards the apex,

two feeble elevations being sometimes visible on the disc before the middle. Elytra fully one-half wider

than the prothorax, moderately long, parallel in their basal half, conjointly rounded at the apex, the

base feebly trisinuate, the humeri rounded ; seriate-punctate, the interstices 2-7 each with a scattered

row of oblong or rounded elevations, those on the third and fifth being the most conspicuous. Metasternum

foveolate at the sides. Ventral segments 1-4 very sparsely and finely, and 5 closely, punctate, the latter

transversely depressed in the middle at the apex in the ¢.

Length 6-9, breadth 24-4 millim. (¢ 2.)

Hab. Mexico, Toxpam (Sallé); Guatemata, Sinanja in Vera Paz (Champion) ;

Nicaragua, Chontales (Belt); Costa Rica, Tucurrique (Mus. Dresden); Panama,

Bugaba, Volcan de Chiriqui (Champion).

Found in plenty in Chiriqui. Differs from the following species in the absence

of the prominences on the prothorax, though two of these are sometimes traceable

on the disc.

2. Anchonomorpha tuberculifera, sp. n. (Tab. V. fig. 1.)

Oblong-ovate, broad, opaque above and slightly shining beneath, pitchy-black, the legs and antenne partly

rufescent; clothed above with minute brown scales, these being coarser and more elongate on the elytral

elevations, and also with scattered, short, erect setae, the inequalities of the surface more or less coated

with an earthy incrustation ; the under surface with a few scattered scales and erect sete; the legs with

setiform scales. Head densely punctate, foveate between the eyes; rostrum moderately curved, stout,

rugosely punctured, 5-carinate; joint 2 of the funiculus slightly shorter than 1. Prothorax a little

broader than long, the apex produced over the base of the head and emarginate in the centre, the sides

rounded at the middle, rapidly converging in front, and sinuate behind, the base strongly bisinuate; the

surface uneven, closely, irregularly punctate, with six prominent rounded tubercles—four in a transverse

series across the middle and one on each side immediately in front of the outer one,—the disc also

longitudinally raised on either side of the middle in a line with the two median tubercles, forming two

conspicuous ridges in front. Elytra moderately long, rather more than one-half wider than the prothorax,

conjointly rounded at the apex, subparallel in their basal half, the humeri prominent, rounded; seriate-

punctate, the interstices 2-7 each with scattered, large, subconical tubercles. Beneath very coarsely

sparsely punctate.

Length 83-10, breadth 33-42 millim. ( 9.)

Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion).

Five specimens. Broader than A. occulta, and with stouter tubercles on the elytra,

the pronotum also conspicuously tuberculate and produced in front over the base of

the head, the under surface coarsely punctate and sparsely setose.

3. Anchonomorpha debilis, sp. n.

Oblong-ovate, shining, black or piceous, the antenne and legs partly rufescent; clothed above with minute

brownish scales and short sete, which are partly hidden by an earthy incrustation ; the under surface

moderately stout and about as long as the prothorax, not carinate; joint 2 of the funiculus a little

shorter and much more slender than 1. Prothorax broader than long, somewhat produced in front over

the base of the head, constricted before the apex, the sides rounded at the middle, rapidly converging in

front, and slightly sinuate behind, the base bisinuate ; the surface uneven, densely rugulosely punctate,

with four conical tubercles placed in an irregular transverse series across the middle and two prominences

at the apex. Elytra fully one-half wider than the prothorax, subparallel in their basal half, conjointly

rounded at the apex; coarsely seriate-punctate, the interstices 2-7 with scattered oblong elevations.

Beneath sparsely punctate; the first ventral segment broadly depressed in the middle, and the fifth

emarginate at the apex and also slightly depressed down the centre, in the ¢.

Length 33-4, breadth 13-13 millim. (¢ @.)

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

Five specimens. This species is allied to A. tuberculifera, but it is very much

smaller and has fewer tubercles on the prothorax, and the rostrum is not carinate.

RHECAS, gen. nov.

Mandibles with a tridentate, downwardly curved, acute edge; rostrum very stout, curved, the scrobes deep,

descending to the lower anterior margin of the eye and commencing on the upperside; mentum

transverse, placed at the apex of a long peduncle, the palpi visible ; antenn inserted near the apex of

the rostrum in both sexes, the funiculus 7-jointed, joint 7 larger than 6; eyes lateral, transverse, not

prominent, separated by a space equalling the width of the rostrum; prothorax and elytra closely

articulated and truncate at the base, the prothorax deeply arcuate-emarginate at the apex beneath, the

elytra connate ; scutellum absent ; anterior cox contiguous ; metasternum short ; ventral sutures very

deep, the segments 2-4 convex, and 2 scarcely as long as 3 and 4 united; legs stout; femora clavate,

The single species referred to this genus has very much the appearance of an

Otiorrhynchid, but the mandibles are formed as in the Hylobiina and the other

characters are as in that group, with the exception of the deep ventral sutures. It is

perhaps nearest allied to Laccoproctus, which also has the prothorax and elytra

subtruncate at the base and the scutellum absent, but in that genus the anterior

coxe are separated, the mandibles are not toothed, the second ventral segment is

longer, &c.

1. Rhecas spurcus, sp.n. (Tab. V. figg. 2, 2a, 3.)

Elongate-ovate, rather convex, opaque, the rostrum and under surface shining, black, the tarsi and antenne

sometimes partly rufescent ; the prothorax and elytra somewhat thickly clothed with coarse, piliform,

brown scales, which are partly hidden by an earthy incrustation, the under surface very sparsely

squamose, the legs with clubbed setiform scales and an earthy coating. Head densely rugulosely

punctate above, transversely strigose beneath ; rostrum (¢) nearly as long as the prothorax, rugosely

twice its length, somewhat rounded at the sides, the apices produced and conjointly rounded ; seriato-

foveate, and with scattered irregular rounded prominences, which are most evident on the apical half.

Venter smooth, with a few fine scattered punctures only. Femora usually with a very short tooth

beneath.

Length 6-8}, breadth 23-33 millim. (d 2.)

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

Seven specimens. The only sexual difference observable is in the sculpture of

the rostrum.

LACCOPROCTUS.

Laccoproctus, Schénherr, Gen. Cure. vii. 2, p. 154 (1843); Lacordaire, Gen. Col. vi. p. 460.

A monotypic genus peculiar to Mexico and Guatemala. Neither Lacordaire nor

Schénherr noted that the mandibles in Laccoproctus are narrow and quite simple at

the edge, whereas in Hilipus and its allies they are broad and tridentate.

rostrum. The eyes in the typical genera (Anchonus, &c.) are depressed and finely

facetted, and placed low down on the globular portion of the head, whereas in

INoptrophorus, Ithaura, and Theognete they are more or less coarsely facetted and

placed at the sides of the rostrum behind. ‘The funiculus of the antenne is 8-jointed

in Anchonus, Rhyparonotus, Cestophorus, and Leprosomus (the two last-mentioned genera

have not yet been detected in Central America), 7-jointed in Oncorrhinus, Dioptro-

phorus, &c., and 6-jointed in Geobyrsa (Anephilus). All are apterous, except

Oncorrhinus, which has a scutellum and fully-developed wings. The apterous species,

as might be expected, are extremely local, and each confined to a limited district, the

winged forms, on the other hand, being somewhat widely distributed.

These insects are chiefly found under the bark of decaying trees, or by beating dead

branches, and some of them are often thicklycoated with an earthy incrustation, which

hides most of the surface-sculpture. I have found it impossible in many cases to identify

specimens till they were cleaned by immersion in caustic potash, which removes the dirt

without loosening the scales. In Anchonus and its allies the scales on the upper surface

of the body are more or less setiform, and sometimes clubbed at the tip ; they vary in

length according to the species, and are often arranged in fascicles on the prothorax

and on the more elevated portions of the elytra. Zyphloglymma, Dury, including a

blind form from Ohio, belongs to this group, near Jthaura. |

the specimens before me, including one from south of our region, the elytra are much

flattened on the disc, with the interstices narrowly and interruptedly carinate, the

carine formed by smooth, oblong, coalescent tubercles; and the prothorax is trans-

versely quadrate, not conspicuously carinate. In Lacordaire’s figure of O. scabricollis

(Gen. Col., Atlas, t. 69. fig. 1) the elytra are represented as uninterruptedly carinate

from the base to the apex.

2. Oncorrhinus latipennis, sp. n. (Tab. V. fig. 5, 3.)

Broad, moderately convex, black, the tarsi and antenne piceous or rufo-piceous, sparsely setose. Rostrum seriate-

punctate, shining at the apex, with a smooth median carina, the apical portion short in the d, and much

longer and almost entirely smooth in the 9; head deeply foveate in the middle in front. Prothorax

flattened on the disc, transversely quadrate, strongly bisinuate at the base and apex, the anterior lobe

considerably produced, the sides hollowed towards the base, the hind angles acute (as seen from above) ;

the surface (except in the hollow space on each side of the anterior lobe) very coarsely, irregularly,

foveolato-punctate, the punctures here and there confluent, and the interspaces sinuously raised and

shining, the disc sometimes with indications of an irregular, abbreviated, median carina. Elytra mode-

rately convex, somewhat heart-shaped, at the base strongly trisinuate and fully one-half broader than the

prothorax, gradually narrowing from the prominent and obliquely subtruncate humeral callosities ; finely

and shallowly seriate-punctate, the punctures becoming evanescent towards the apex, the interstices each

with a scattered series of small, rounded, shining tubercles, each of these bearing a stout, decumbent,

ochreous, piliform scale, the third subcarinate at the base. Femora coarsely punctate ; tibie in both.

sexes angularly dilated on the inner side before the middle, the anterior pair acutely so. Venter depressed

in the middle at the base in the ¢.

Ilab. Nicaragua, Chontales (Belt, Janson); Panama, Volcan de Chiriqui (Champion).

Found in numbers in Chiriqui. Very like A. nodulosus, Fahr., from Caracas, &c.,

but with the prothorax wider at the base, and the smooth, setigerous, elytral tubercles

rounded, instead of oblong *. The more convex, differently sculptured, and somewhat

heart-shaped elytra separate it at a glance from 0. scadricollis.

Lacordaire, Gen. Col. vi. p. 862 (part.) ; Faust, Deutsche ent. Zeit. 1892, p. 20.

Nearly one hundred species of Anchonus have been described, mostly from the

Antilles or the mainland of Tropical America, the genus extending from Florida to

Chile, and also occurring in the Galapagos and Cocos Islands; it is extremely well

represented within our limits. The chief characters of the genus are the 8-jointed

funiculus and the contiguous anterior coxe, Cestophorus differing from it in having a

Museum; but this insect has the prothorax longer and more parallel-sided, with a less pronounced anterior

lobe, and the entire surface foveolato-punctate, the rostrum smoother, and the head trifoveate. The habitat

relatively longer scape to the antenne and the anterior coxe not quite touching. The

males are separable from the females by the shorter and less cylindrical apical portion

of the rostrum, and they often have the venter depressed in the middle at the base.

Five specimens. “More robust than A. articulatus, the prothorax less dilated at

the sides and more sparsely granulate, the tubercles of the elytra rounded, larger, and

fewer in number, the humeri angular and projecting. The elytral elevations are nearly

as large as in the Mexican A. nodosus.

9. Anchonus articulatus, sp.n. (Tab. V. figg. 7, 7a, b, 2.)

Oblong, rather broad, black, the funiculus and tarsi obscurely rufescent; the sets very short, fine, and

finely granulate.

Length 64-8, breadth 31-31 millim. (¢ 2.)

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

Three males and two females. Differs from A. diolleyi, with which it agrees, in

having the first and second ventral segments separated by a deep suture, by the obtuse

humeri, &c. The prothorax is sinuously narrowed behind, so that the hind angles are

rectangular, as viewed from above; the disc is closely granulate, except along the

middle.

8. Anchonus brevisetis, sp. n. (Tab. V. figg. 8, 8a, 2.)

Oblong, black, the antenne and tarsi obscurely rufescent, the surface usually coated with an earthy incrustation ;

the setee very short, fine, and scattered, not forming fascicles on the prothorax or elytra. Rostrum (¢)

Length 53-72, breadth 23-34 millim. (¢ 2.)

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

ANCHONUS. Tt

Ten specimens, most of them encrusted with dirt, and varying greatly in size. In

this species, as in the allied A. articulatus, the first two ventral segments are separated

by a deep suture (instead of being fused together at the middle, as usual in this genus).

The setosity is short and scattered, not forming fascicles on the prothorax. The

prothorax is coarsely, closely punctate, with the raised interspaces smooth, shining, and

subgranulate. The elytral tubercles are small.

4, Anchonus mirus. (Tab. V. fig. 9, 9a, ¢; 96, antenna.)

Anchonus mirus, Faust, Deutsche ent. Zeit. 1892, pp. 28, 48 (¢)’.

Elongate, moderately convex, deep black, the antenne and tarsi obscurely rufescent; the sete short, coarse,

and very scattered, but forming four small fascicles on the prothorax. Rostrum stout, cylindrical, curved,

coarsely punctate to the tip, the widened apical portion rather long in both sexes, but a little longer and

narrower in the ¢ than in the 9; antenne stout, the funiculus short, joint 2 barely twice as long as 1,

7 and 8 transverse, 8 nearly as wide as the club. Prothorax slightly longer than broad, widest a little

before the middle, broader and more rounded at the sides in the ¢ than in the @, deeply constricted

before the apex and much narrowed behind; the surface trisulcate, extremely coarsely rugose, with the

ruge sinuous or transverse and shining at the summit, binodose and fasciculate at the apex and on the

middle of the disc; the flanks very coarsely punctate. Elytra oblong-ovate, at the base wider than the

prothorax ; very coarsely seriate-punctate, the interstices transversely rugose, conspicuously tuberculate,

and granulate, the elevations tending to coalesce and form interrupted caring, especially at the base of

the third and fifth interstices. Beneath very coarsely punctate. Femora shallowly, somewhat finely

punctate. Third tarsal joint moderately dilated, not very deeply excised at the apex.

Length 65-7, breadth 2-24 millim. (¢ 9.)

Hab. GuateMALa !, Totonicapam (Champion), Tecpam (Conradt).

We possess seven specimens of this species, all from a high elevation in the Los

Altos region. The stout and comparatively short antenne, with strongly transverse

eighth funicular joint, and the somewhat feebly dilated third tarsal joint, separate

A, mirus* from the other Central-American forms, the following excepted.

The antenne in the male are inserted further from the apex than usual in this

genus, so that there is very little difference observable in the form of the rostrum in

the two sexes.

5. Anchonus mexicanus, sp. n. (Tab. V. figg. 10, 10a, ¢.)

Oblong-ovate, black, the antennz and tarsi partly rufescent; the sete extremely short, scattered, and incon-

spicuous. Rostrum stout, curved, shorter than the prothorax, feebly constricted at the base, rugosely pune-

tured and longitudinally wrinkled, the scrobes extending along the underside; antenne stout, the funiculus

short, joints 7 and 8 transverse, 8 nearly as wide as the club, and much wider than 7. Prothorax longer

than broad, rounded at the sides, narrowing and strongly constricted in front and narrowing behind; the

surface, except along a narrow smooth space down the middle, very coarsely, irregularly punctate, the

interspaces here and there sinuously raised and shining on the disc and granulate at the sides, Elytra

oblong-ovate, at the base slightly wider than the prothorax ; seriate-punctate, the interstices transversely

wrinkled and finely granulate, 2-7 each with a series of oblong or rounded, not very prominent, tubercles,

* Dr. Heller has been kind enough to compare one of our specimens with the type.

these forming carine at the base of 3 and 5, and all finely granulate. Beneath and the femora coarsely

punctate. Third tarsal joint moderately dilated, not very deeply excised at the apex.

Length 6-64, breadth 23-24 millim. (<.)

Hab. Muxico, Mexico city (Hoge).

Three specimens. Allied to the Guatemalan A. mirus, but less elongate, with the

rostrum shorter and slightly constricted at the base, the antenne not quite so stout,

the prothorax less rugose, with much more definite punctuation, the elytra with less

prominent, finely granulate elevations. The distinctly constricted rostrum and the

form of the antenne, &c. separate it from A. elongatus and various other Mexican

forms. In dirty specimens the small, smooth, granular elevations are conspicuous on

both the prothorax and the elytra.

6. Anchonus gibbirostris, sp. n. (Tab. V. figg. 11, lla, 8, ¢.)

Elongate, nigro-piceous or black, the antenne and tarsi obscurely rufescent ; the setee rather long and coarse,

and arranged into fascicles on the prothorax and elytra. Rostrum (¢) stout, cylindrical, strongly

curved, gibbous above near the base, densely, rugosely punctate and minutely granulate to the tip,

(2 ) coarsely, closely punctate, smoother at the tip. Prothorax slightly longer than broad, narrowed behind

and constricted in front, flattened on the disc, the sides rounded at the middle; the surface irregularly

granulate, except along the depressed median space and a sinuous space midway between this and the

margin, which are smooth, and with two more or less distinct setigerous elevations at the apex and two

more on the disc; the flanks coarsely punctate. Hlytra ovate, convex, wider than the prothorax, but of

about the same width at the base, interruptedly seriate-punctate, the interstices 2-7 each with a scattered

series of oblong or rounded, prominent, setigerous, faintly granulate tubercles, the basal margin raised.

Beneath very coarsely, sparsely punctate. Femora coarsely punctate and minutely granulate.

Length 54-64, breadth 23-3 millim. (¢ 9.)

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

Twelve specimens, from a limited district in the forest-clad mountains to the north

of the Polochic Valley. Distinguishable from all the other Central-American species of

the genus by the gibbous rostrum. The elevations on the prothorax are partly formed

by the fasciculate arrangement of the sete, those on the elytra being more prominent.

The rostrum is not constricted at the base.

7. Anchonus nodosus, sp. n. (Tab. V. figg. 12, 124, ¢.)

Anchonus nodosus, Chevr. in litt.

Elongate, very convex, black, the antenne and tarsi obscurely rufescent; the sete very short and scattered.

Rostrum (¢) stout, cylindrical, strongly curved, coarsely punctate to the tip, feebly constricted at the

base, ( 2 ) slightly thickened towards the base, and smoother and more shining at the apex; joint 2 of

the funiculus twice as long as 1. Prothorax about as broad as long, nearly or quite as wide as the

elytra, strongly constricted behind and also before the apex, the sides rounded ; the surface very uneven,

coarsely nodose and granulate laterally and also along either side of the depressed median space, for the

rest smooth ; the flanks coarsely punctate. LElytra at the base very little wider than the prothorax,

convex, ovate; each with about twelve very prominent, large, rounded or oblong, granulate elevations on

the dise and scattered smaller tubercles towards the sides, between which seriate punctures are visible.

Beneath shining, very coarsely punctate. Femora granulate.

Length 7-10, breadth 3}-43 millim. (¢ 2.)

ANCHONUS. 73

Hab. Mexico (Mus. Brit.), Sierra de Durango (Flohr), Orizaba, Toxpam (Sal/é),

Jalapa (Hoge).

This is the largest and most distinct of the Central-American Anchoni; it is not

rare in the State of Vera Cruz, whence we have received a long series. The tubercles

on the elytra are large and very prominent, though variable in size, and there are also

six on the disc of the prothorax and two oblong prominences at the apex in the middle.

The prothorax appears to be transversely gibbous and trisulcate in the specimens with

very prominent elevations on the disc. In one of those from Durango the tubercles of

the elytra are smaller than usual.

8. Anchonus silvicola, sp. n. (Tab. V. figg. 13, 134, 3.)

Elongate, black, the antenne and tarsi obscurely rufescent; the sete rather long and coarse and arranged

in fascicles on the prothorax and elytra. Rostrum (¢) stout, curved, cylindrical, rugosely punctate to

the tip and obsoletely carinate, (2 ) smoother and shining at the tip. Prothorax about as long as broad,

a little flattened on the disc, rounded at the sides, much narrowed in front and behind, and moderately

constricted before the apex ; the surface sparsely granulate, except along the broad depressed median

space and a sinuous space midway between this and the margin, which are smooth, with two feeble

setigerous prominences at the apex and two or more on the disc; the flanks sparsely punctate. LElytra

a little broader than the prothorax, and of about the same width at the base, convex, ovate, coarsely

seriate-punctate, the interstices 2-6 each with a scattered series of oblong, prominent, setigerous, finely

granulate tubercles, the basal margin raised. Beneath coarsely, sparsely punctate. Femora coarsely

punctate and obsoletely granulate.

Length 54-64, breadth 2-23 millim. (¢ 2.)

Hab. Guatemaua, Sinanja, Sabo, and Purula in Vera Paz (Champion).

Seven specimens, from the mountains to the south of the Polochic Valley. Very

like A. gibbirostris, but easily separable therefrom by the non-gibbose rostrum, which

is also less densely punctate and obsoletely carinate, with the widened apical portion

relatively shorter in the male. Two females from Cerro Zunil, on the Pacific slope,

may belong here; but they have the granular elevations on the prothorax more

numerous and tending to form transverse or sinuous ruge, and the rostrum very slightly

thickened towards the base. ‘The less rugose surface, and the prominent, scattered,

fasciculate tubercles on the elytra, the elytra themselves being less widened at the base,

distinguish this species at once from A. elongatus.

9, Anchonus carinirostris, sp.n. (Tab. V. figg. 14, 14a, ¢.)

Oblong, black or piceous, the antenne and tarsi more or less rufescent ; the sete coarse, scattered, semierect,

and arranged in fascicles on the prothorax and elytra. Rostrum (<¢ ) curved, distinctly thickened towards

the base and there very feebly constricted, coarsely seriate-punctate, with the interspaces finely carinate,

(2) shining and sparsely, finely punctate at the tip. Prothorax broader than long, somewhat flattened

on the disc, nearly as wide as the elytra, the sides much dilated at the middle and abruptly constricted

before the apex ; the surface sparsely punctate and minutely granulate laterally and along each side of

the broad flattened median space, and binodose at the apex and on the disc, for the rest smooth. Elytra

slightly wider at the base than the prothorax, convex, ovate, with interrupted rows of shallow, somewhat

widely separated punctures, the interstices 2-7 each with a scattered series of setigerous tubercles, those

minutely granulate.

Length 5-6, breadth 23-23 millim. (d .)

Hab. Guatemata, Cahabon, Senahu, Sinanja and Purula in Vera Paz (Champion).

Numerous examples, most of which are in very clean condition. In this species the

sculpture of the prothorax and elytra is similar to that of A. gibbirostris, from which

the present insect differs in its much smaller size and less elongate shape, the carinate

non-gibbose rostrum, the transverse prothorax, &c. The prothorax 1s quite smooth

down the middle and along a sinuous space between this and the margin.

10. Anchonus penicillatus, sp.n. (Tab. V. figg. 15, 15a, ¢.)

Oblong, black, the antennz and tarsi more or less rufescent ; the setz coarse, rather long, semierect, forming

six fascicles on the prothorax. Rostrum (¢) curved, subeylindrical, coarsely punctate to the tip, and

longitudinally wrinkled, (2) shining and more sparsely punctate at the tip. Prothorax broader than

long, much narrowed behind and narrowed and abruptly constricted in front, narrower than the elytra ;

the surface granulate, except down the middle and along a narrow sinuous space midway between this

and the margin, binodose at the apex, and with an abbreviated median carina. Elytra ovate, slightly

wider at the base than the prothorax, coarsely seriate-punctate, the interstices 2-7 each with a series of

setigerous tubercles, the suture also tuberculate beyond the middle. Beneath very coarsely punctate.

Femora closely, coarsely punctate.

Length 4-5}, breadth 2-23 millim. (¢ 9.)

Hab. Guaremata, Senahu, San Juan, Sinanja, Sabo, San Gerdnimo (Champion),

Coban (Conradt).

Not rare in the humid forest districts of Alta Vera Paz. Chiefly distinguishable by

the granulate, faintly carinate, fasciculate, posteriorly narrowed prothorax, the seriate-

tuberculate, ovate elytra, the roughly punctured femora, and the coarse semierect

setosity. The less dilated and more closely granulated prothorax, the non-carinate

rostrum, &c., separate it from A. carinirostris, an insect inhabiting the same districts.

11. Anchonus abnormis. (Tab. V. figg. 16,164, 2.)

Anchonus abnormis, Fahr. in Schonh. Gen. Cure. vii. 2, p. 893°.

Hab. Mexico (coll. Chevrolat}, in Mus. Holm.).

The type of this small species, a female, has been lent me by Dr. Aurivillius.

It is in very dirty condition, but may be recognized by the prominent tuberculiform

elevations on the prothorax and elytra; the interspaces on the prothorax are sparsely

‘granulate; the scape reaches to the middle of the eyes, which are rather large ; the

under surface is very sparsely, finely punctate; the seriate punctures on the elytra are

very coarse and deep towards the sides; the femora are comparatively smooth. Length

43 millim. |

A, abnormis was not noticed by Faust in his papers on the genus.

ANCHONUS. (oy

12. Anchonus obovatus, sp. n. (Tab. V. figg. 17, 174, 3.)

Obovate, robust, convex, nigro-piceous or black, the antenne and tarsi obscurely rufescent ; the set coarse,

rather long, forming conspicuous erect fascicles on the prothorax and on the elytra, chiefly placed on the

elevated portions of the surface. Rostrum stout, curved, cylindrical, closely, rugosely punctate to the tip,

not carinate; joint 2 of the funiculus about twice as long as 1. Prothorax about as broad as long,

narrowed and constricted in front and narrowed behind, the sides rounded at the middle; the surface

closely punctate, in some specimens with a smooth slightly raised median line, binodose and fasciculate at

the apex, and with two other fascicles on the disc and one on each side before the middle. Elytra ovate,

convex, at the middle fully one-half wider than the prothorax, but at the base scarcely wider than it,

seriate-punctate, the interstices 2-6 each with a scattered series of very prominent oblong or rounded

setigerous tubercles, the suture also tuberculate beyond the middle. Beneath coarsely, sparsely punctate.

Femora coarsely punctate.

Length 6-7, breadth 3-34 millim. (d @.)

Hab. Costa Rica, Tucurrique (Mus. Dresden); Panama, Volcan de Chiriqui

(Champion).

Eighteen specimens, mostly in very clean condition. A rather large, convex species,

of obovate form, with the rostrum coarsely punctate to the tip in both sexes, the

prothorax coarsely, rugosely punctate and conspicuously fasciculate, and the elytra

with prominent setigerous tubercles. There is no trace of granulation on the pro-

thorax, the punctures appearing variolose in dirty examples.

13. Anchonus validus, sp. n.

Obovate, robust, convex, black ; the sete coarse and rather long, forming fascicles on the prothorax and on

the elytra, chiefly placed on the elevated portions of the surface. Rostrum very stout, curved, cylindrical,

nearly three times as long as 1. Prothorax broader than long, narrowed and constricted in front and.

narrowed behind, the sides rounded at the middle; the surface densely, rugosely punctate, the intervening

ruge here and there transversely confluent. Elytra ovate, convex, at the middle about one-half wider

than the prothorax, seriate-punctate, the interstices 2-6 each with a scattered series of moderately

prominent oblong setigerous tubercles, those on 2 and 3 larger and more conspicuous than the rest.

Legs very stout, the femora coarsely, rugosely punctate.

Length 73, breadth 4 millim. (¢-)

Hab. Guaremana, San Juan in Vera Paz (Champion).

One specimen, from the vicinity of the Polochic Valley. Very like A. obovatus,

from Costa Rica and Chiriqui, but larger and more robust, the prothorax transverse,

relatively broader, and with the ruge transversely confluent, the elytral elevations

less prominent, especially towards the sides, the tibie straighter.

14. Anchonus nodipennis, sp.n. (Tab. V. figg. 18, 184, ¢.)

Obovate, convex, black, the funiculus and tarsi obscurely rufescent, thickly clothed with an earthy incrustation ;

the sete short, fine, and scattered, but coarser, longer, and clustered together on the elevated portions of

the surface, forming eight fascicles on the prothorax. Rostrum stout, cylindrical, feebly curved, coarsely,

seriately punctate. Prothorax transverse, somewhat flattened on the disc, dilated at the sides a little

before the middle, gradually narrowing thence to the base and abruptly constricted and narrowed in

front; the surface very closely, coarsely punctate, with the narrow raised interspaces here and there

shining and granulate, distinctly binodose at the apex and on each side before the middle, and less

convex, wider at the base than the prothorax, seriate-punctate, the interstices 2-7 each with a series of

oblong or rounded, prominent, setigerous tubercles, those at the base of 3 and 5 cariniform, the suture

also tuberculate a little beyond the middle. Beneath very coarsely punctate, the ventral segments 1 and 2

connate. Femora coarsely punctate and minutely granulate.

Length 63-8, breadth 33-37 millim. (<¢.)

Hab. Nicaragua, Chontales (Belt).

Two males. In this species the prothorax is distinctly binodose on each side before

the middle, so as to appear subangularly dilated. It is not unlike A. obovatus and

A. validus, but has a more transverse, finely granulate prothorax ; the elytra are less

rounded at the sides, broader at the base, and with more numerous tubercles, these

being not so prominent as in A. obovatus; and the setosity is shorter.

15. Anchonus helleri, sp. n. (Tab. V. figg. 19,19 a, ?.)

Oblong-obovate, slightly depressed above, black ; the sete coarse and forming fascicles on the prothorax and

elytra. Rostrum moderately stout, slightly thickened towards the base, coarsely punctate. Prothorax

a little broader than long, constricted and much narrowed in front and gradually narrowing behind,

coarsely varioloso-punctate, with the narrow interspaces here and there granulate, distinctly binodose at

the apex and also on each side before the middle, and with the sete clustered together at these places,

the disc with an abbreviated sinuous smooth median line anteriorly. Elytra oblong-ovate, at the base a

little broader than the prothorax, seriate-punctate, the interstices 2-7 each with a scattered series of

oblong or rounded setigerous tubercles, those at the base of 3 and 5 forming a short ridge, the suture

granulate. Beneath somewhat coarsely punctate; ventral segments 1 and 2 connate and level at the

middle.

Length 8, breadth 41, millim. (9.)

Hab. Costa Rica, Piedras Negras (Mus. Dresden).

One specimen, communicated by Dr. Heller. Not unlike A. horridus, but much

larger, with a rougher fasciculate prothorax, which is binodose laterally and in

front. The connate first and second ventral segments, the narrower terminal joint

of the funiculus, and the less rounded sides of the prothorax and elytra separate it

from A. articulatus and A. brevisetis; and the more depressed form, &c., from

A. obovatus and A. validus.

16. Anchonus subcristatus, sp. n. (Tab. V. figg. 20, 204, 3.)

Elongate-ovate, black, the antenne and tarsi obscurely rufescent; the sets long, coarse, and abundant, and

showing a tendency to form four fascicles on the prothorax. Rostrum (¢) curved, stout, cylindrical,

slightly constricted at the base, coarsely punctate and longitudinally wrinkled, ( 2 ) slightly thickened

towards the base, and closely, coarsely punctate to the tip. Prothorax about as long as broad, a little

shorter in the 2, the sides rounded at the middle, converging thence to the base and apex, and constricted

in front; the surface closely punctate, except along a narrow space down the middle, with the inter-

spaces opaque and here and there transversely or obliquely raised, feebly binodose and fasciculate at. the

apex, the set also forming two indistinct fascicles on the disc. Elytra ovate or oblong-ovate, convex,

at the base scarcely wider than the prothorax ; seriate-punctate, the interstices 2-7 each with a series

of oblong or rounded prominent setigerous tubercles, the suture also tuberculate. Femora coarsely

punctate.

ANCHONUS. qT

Hab. Guaremata, Cerro Zunil, Pacific slope (Champion).

Three males and one female, varying a little in the length of the prothorax and

elytra. This is one of several very closely allied Guatemalan forms. From A. cirratus,

of the Atlantic slope, it may be separated by the less dilated prothorax (especially

noticeable in the males), the sete on which form about four fascicles only, the more

closely tuberculate elytra, and the rostrum in both sexes coarsely punctate to the tip,

it also being more thickened towards the base in the female. From A. coarctatus,

from the same district, the less constricted base of the prothorax and of the elytra,

and the more closely punctured and less uneven surface of the former, will serve to

distinguish it.

17. Anchonus coarctatus, sp.n. (Tab. V. figg. 21, 21a, 2.)

Elongate-ovate, narrow, black, the antenne and tarsi rufescent; the sete coarse, forming fascicles on the

prothoracic and elytral elevations. Rostrum cylindrical, strongly curved, stout, coarsely seriate-punctate,

distinctly carinate down the middle and obsoletely so towards the sides. Prothorax as long as broad,

widest at the middle, sinuously narrowing thence to the base, and narrowing and constricted in front,

the hind angles subrectangular: the surface very uneven, coarsely, closely punctate, except along a

narrow depressed space down the middle, binodose at the apex and also on the middle of the disc, and

podose at the sides, the elevations conspicuously fasciculate, the interspaces between the punctures here

and there raised and faintly granulate. Elytra convex, ovate, constricted at the base and there a little

wider than the prothorax, the basal margin appearing raised and the humeri rather prominent; coarsely

seriate-punctate, the interstices 2-5 each with a scattered series of very prominent, oblong, setigerous

tubercles. Femora somewhat finely punctate.

Hab. Guaremata, Cerro Zunil, Pacific slope (Champion).

Two males. Recognizable amongst its allies, A. subcristatus, &c., by the constricted

base of the prothorax and of the elytra, the carinate rostrum, the uneven, rugose, and

conspicuously fasciculate prothorax, and the prominent setigerous tubercles on the

interstices 2-5 of the elytra.

18. Anchonus cirratus, sp. n.

Oblong, black or nigro-piceous, the antenne and tarsi more or less rufescent; the sete long, coarse, and semi-

erect, forming numerous fascicles on the prothorax and elytra. Rostrum (¢) curved, slightly thickened

towards the base, and there very feebly constricted, coarsely punctate, obsoletely 5-carinate, (9) more

thickened towards the base, finely punctured and shining at the tip. Prothorax broader than long,

somewhat flattened on the disc, a little rounded at the sides, much narrowed behind, and narrowed and

constricted in front ; the surface rather uneven, closely varioloso-punctate, except along a narrow space

down the middle, and more or less distinctly binodose in front, the sete arranged in about twelve

conspicuous fascicles—three down each side of the middle of the dise and three on each lateral margin.

Elytra ovate, convex, about as wide at the base as the prothorax, coarsely seriate-punctate, the interstices

2-7 each with a widely scattered series of setigerous tubercles. Beneath sparsely punctate. Femora

coarsely punctate.

78 RHYNCHOPHORA.

Twelve examples. ‘his is a species with a closely varioloso-punctate prothorax, on

which the ochreous sete are clustered together in about twelve fascicles—a double

series down the middle of the disc and one on each lateral margin. The rostrum is

conspicuously thickened towards the base in the female, and slightly so in the male.

The elytra are similar in shape and sculpture to those of A. penicillatus and other allied

forms. ‘The peculiar sculpture of the prothorax distinguishes it from many very similar

species.

19. Anchonus granulatus, sp.n. (Tab. V. figg. 22, 22a, ¢.)

Oblong-ovate, black, the antenne and tarsi obscurely rufescent; the sets long and coarse, and arranged in

fascicles on the more elevated portions of the prothorax and elytra. Rostrum (¢) stout, cylindrical,

curved, coarsely seriate-punctate, not carinate, (Q) less coarsely punctate towards the tip, which is

shining. Prothorax about as long as broad, somewhat rounded at the sides, narrowing and strongly

constricted in front and narrowing behind; the surface, except along a narrow, flattened, smooth space

down the middle and a narrow, irregular, sinuous space midway between it and the margin, closely set

with small, smooth, shining tubercles, and more or less distinctly binodose and fasciculate at the apex,

and sometimes on the middle of the disc also; the flanks very coarsely punctate. Elytra oblong-ovate,

wider at the base than the prothorax, somewhat flattened on the disc and abruptly declivous at the apex ;

very coarsely seriate-punctate, the interstices 2-6 uneven, and here and there minutely granulate, each

with a series of oblong, prominent, setigerous tubercles, these forming carine at the base of 3 and 5,

the tubercle on 3 at the commencement of the apical declivity larger than the rest, this interstice being

interruptedly raised thence to the apex. Beneath sparsely punctured. Femora coarsely punctate.

Length 54-63, breadth 23-3 millim. (¢ @.)

Hab. Mexico, Toxpam (Sallé), Jalapa (Hége).

Five specimens. This is one of several very closely allied Mexican forms, and

amongst these it may be identified by the coarsely granulated prothorax (a character

separating the species from all the other Central-American Anchont known to me), the

unusually large tubercle on the third interstice at the commencement of the apical

declivity, and the long, coarse setosity. As in A. elongatus, the sexual difference in

the form of the rostrum is not very pronounced.

20. Anchonus salebrosus, sp. n. (Tab. V. fig. 23, ¢.)

Oblong-ovate, black, the antenne and tarsi obscurely rufescent, the surface usually thickly covered with an

earthy incrustation; the sete short, erect, and rather coarse. Rostrum stout, curved, cylindrical,

feebly constricted at the base, coarsely seriate-punctate, the interspaces longitudinally wrinkled, the apical

portion in the 2 shining, closely and more finely punctate. Prothorax about as long as broad, rounded

at the sides, constricted and narrowed in front and narrowed behind ; the surface, except down a narrow

median space and along a narrow sinuous space midway between this and the margin, coarsely, irregularly

punctate, with the interspaces here and there raised and granulate, more or less distinctly binodose at the

apex. lytra oblong-ovate, at the base slightly wider than the prothorax ; coarsely seriate-punctate, the

interstices uneven and sparsely, minutely granulate, 2-7 each with a series of conical setigerous tubercles,

these here and there united, forming short carine at the base of 3 and 5 and elsewhere on the disc, the

elevations on the apical declivity subequal in size. Beneath sparsely, coarsely punctate.

ANCHONUS. 79

Numerous examples, most of which were in such a dirty condition that they had to

be cleaned before the sculpture could be seen. Very like A. granulatus, and perhaps

nothing more than an extreme form of it, but differing from that species in the finely

granulated, coarsely punctured prothorax, the more uniform size of the elevations on

the third elytral interstice towards the apex, and the shorter setosity. ‘There is a good

deal of variation in the development of the tubercles on the elytra, these being mostly

conical in shape and coalescing on the disc into short ridges.

21. Anchonus sallei, sp.n. (Tab. V. fig. 24, ¢.)

Anchonus sallei, Faust, in litt.

Oblong-ovate, black, the antennz and tarsi more or less rufescent ; the sete extremely short. Rostrum stout,

cylindrical, curved, closely and rugosely punctured to the tip, the interspaces irregularly, longitudinally

wrinkled, the widened apical portion short and dull in the ¢ and a little longer, shining, and parallel-

sided in the 2. Prothorax distinctly flattened on the disc, slightly broader than long, rounded at the

sides, constricted and narrowed in front and narrowed behind; the surface coarsely, closely, irregularly

punctate, with the interspaces here and there raised and shining, shallowly sulcate down the middle, more

or less distinctly binodose at the apex, on the middle of the disc, and at the sides. Elytra oblong-ovate,

more or less flattened on the disc and abruptly declivous at the apex, at the base wider than the prothorax;

coarsely seriate-punctate, the interstices 2-7 uneven, and here and there minutely granulate, each with

a series of oblong or rounded, moderately prominent, setigerous tubercles, these forming a carina at the

base of 3 and 5, 2 with the larger tubercle at the commencement and middle of the apical declivity sub-

equal in size. Beneath very coarsely punctate.

Length 53-6, breadth 2}-23 millim. (¢ @.)

Hab. Muxico (Mus. Brit.), Toxpam (Sallé), Jalapa (Hoge).

Seven examples. We have received one of Sallé’s specimens of this insect from the

Dresden Museum, labelled with the MS. name of A. salle, Faust. Compared with its

Mexican allies, the present species may be known by the extremely short setosity of

the upper surface, the coarsely, irregularly, somewhat confluently punctured prothorax,

and the more or less flattened disc of the elytra, the latter with moderately prominent

tubercles, the larger ones at the commencement and middle of the apical declivity being

subequal in size. The single (2) specimen from Jalapa has the elytra more flattened

on the disc, and the tubercles on this portion of the surface less raised, forming inter-

rupted caring.

Hab. Mexico ? (coll. Chevrolat*), Toxpam (Sallé).

I am unable to separate A. pedestris from A. elongatus, the type or co-types of which

are before me, as well as a specimen from the Sallé collection. The setosity of the

upper surface is extremely short, showing no tendency to form fascicles on the pro-

thorax. In the type of A. elongatus the tubercles on the elytra form a conspicuous

ridge at the base of the third and fifth interstices, and the elytra themselves area little

more elongate than in the two other examples seen. The eighth joint of the funiculus

is transverse, and a good deal wider than the seventh. From dA. sal/@i it may be

distinguished by its more elongate shape, the relatively longer prothorax, and the

somewhat numerous tubercles on the second elytral interstice towards the apex, these

being subequal in size. ahreus’s type is figured.

23. Anchonus oblongus, sp. n. (Tab. V. fig. 26, 26 a, 2.)

Oblong-ovate, nigro-piceous or black, the antenne and tarsi obscurely rufescent ; the sete coarse, rather short,

and scattered. Rostrum stout, curved, slightly thickened towards the base, and there feebly constricted,

closely punctate throughout, the punctuation coarse, but becoming finer at the tip. Prothorax a little

broader than long, somewhat flattened on the disc, widest at the middle, gradually narrowing thence to

the base, and narrowing and constricted in front; the surface coarsely, closely punctate, except along

a narrow, smooth, somewhat convex space down the middle and on an irregular sinuous flattened space

midway between this and the margin, the interspaces between the punctures dull and here and there

obliquely or sinuously raised, in one specimen faintly granulate, the sete showing a tendency to form two

fascicles at the apex and two on the middle of the disc. Elytra oblong-ovate, convex, of the same width

at the base as the prothorax ; coarsely seriate-punctate, the interstices 2-7 each with a series of oblong

or rounded setigerous tubercles, those at the base of 3 and 5 cariniform, the suture also tuberculate

beyond the middle. Femora coarsely rugosely punctate.

Length 5-54, breadth 2-24 millim. (@.)

Hab. Guatemaua, Capetillo (Champion).

Two specimens, one in perfectly clean condition. Very like A. penictllatus, but

more elongate, the prothorax coarsely, closely punctate, except down the middle and

along a narrow space on either side of it (instead of being sparsely granulate), the sete

much shorter, and not forming conspicuous fascicles on the prothorax. ‘The narrower

and more elongate form, the irregularly punctured prothorax, the sides of which are

less rounded and the disc without prominent fascicles, and the slightly constricted,

closely punctured rostrum separate this species from A. cirratus(?). A specimen ( ¢ )

from San Gerénimo may also belong here ; but it has longer sete, and the elytra are

here and there minutely granulate, both on the flattened and on the elevated portions

of the surface.

24. Anchonus brevipennis, sp.n. (Tab. V. figg. 27, 27 4, 2 .)

Obovate, black, the antennee and tarsi obscurely rufescent; the sete very short, but coarse, and arranged in ©

fascicles on the more elevated portions of the surface. Rostrum curved, stout, cylindrical, slightly

constricted at the base, closely seriate-punctate, with the interspaces longitudinally wrinkled, the apical

portion densely punctured in both sexes. Prothorax about as long as broad, rounded at the sides,

narrowed and constricted in front and narrowed behind; the surface uneven, closely, coarsely punctate,

shallowly suleate down the middle, and binodose at the apex and on the middle of the disc. Elytra

convex, ovate, comparatively short ; seriate-punctate, the interstices 2-6 each with a scattered series of

prominent, oblong, setigerous tubercles, 7 with small conical elevations.

ANCHONUS. 81

Two specimens. Very like A. verrucosus, but with the rostrum less constricted at

the base, the prothorax not tuberculate at the sides, the prominences on the disc

of the elytra stouter and less conical in shape. Larger, broader, and more robust

than A. spiculosus, with the rostrum distinctly constricted at the base, the prothorax

quadrinodose, and the elytra with stouter setigerous prominences.

25. Anchonus spiculosus, sp.n. (Tab. V. figg. 28, 28a, 2.)

Oblong-ovate, black, the antenne and tarsi rufescent ; the sete very short, scattered, fine, and inconspicuous.

Rostrum stout, cylindrical, strongly curved, rugosely punctured, smoother at the tip. Prothorax a little

longer than broad, widest at the middle and narrowing thence to the base and apex, and constricted in

front; the surface uneven, shining, coarsely, rugosely punctate, the interspaces here and there raised and

granulate. Elytra convex, ovate; coarsely seriate-punctate, the interstices 2-7 each with a series of

smooth, shining, conical tubercles, those on 2-5 intermixed with smooth oblong elevations. Femora

_ coarsely punctate.

Length 37, breadth 14 millim. (9.)

Hab. Mexico (Sallé).

One specimen, not labelled with any definite locality. A very small isolated form,

distinguishable by the rugosely punctate, shining prothorax, the smooth, conical or

oblong tubercles on the elytra, and the short, fine, inconspicuous sete.

26. Anchonus quadrituberculatus, sp.n. (Tab. V. figg. 29, 29a, 2.)

Oblong-ovate, black, the apex of the rostrum, the antenne and tarsi rufescent; the sete short, erect, and

scattered. Rostrum stout, curved, slightly thickened towards the base, and there feebly constricted,

coarsely punctate, the punctuation becoming fine at the tip. Prothorax nearly as long as broad, widest

a little before the middle, obliquely narrowing thence to the base, and narrowing and constricted imme-

diately before the apex; the surface irregularly punctate and granulate, except along a narrow space down

the middle, and with two small shining nodules at the apex, two in a line with them on the middle of the

disc, and some others near the anterior angles, and two larger and more prominent elevations at the sides

before the middle ; the flanks closely punctate. Elytra ovate, convex ; seriate-punctate, the interstices

1-7 each with a scattered series of shining, conical tubercles, which are here and there placed close

together, so as to form short ridges.

Length 43, breadth 2 millim. (2.)

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

One specimen. The chief characters of this insect are the two smooth, prominent

tubercles on each side of the prothorax before the middle (the margins appearing

strongly sinuate), and the four smooth, minute, nodiform elevations on its disc, the

elytral interstices 1-7 each with a series of smooth, conical tubercles, which are here

and there contiguous. The non-carinate, non-tuberculate rostrum separates it from

A. verrucosus and A. tuderculirostris; and the basally constricted rostrum, different

prothoracic sculpture, &c., from A. spiculosus, near which the species seems best

placed.

Hab. Nicaragua, Chontales (Belt: ¢ ); Costa Rica, Tucurrique (Jus. Dresden: 2).

One pair. A small species, recognizable by the finely carinate, posteriorly con-

stricted rostrum, the tuberculate prothorax, and the convex, ovate, tuberculate elytra.

The setosity is short and scattered, nowhere forming fascicles. The rostrum is

distinctly tuberculate in front of the basal constriction. oe

Hab. Costa Rica, San Carlos (Mus. Dresden).

One specimen. Very like A. verrucosus, and perhaps an extreme form of it, but

with the tubercles on the elytra reduced to very small conical prominences, the

prothorax less uneven above, with some very small tubercles at the sides and along

either side of the middle of the disc. The rostrum is a little less constricted at the

Distinguishable by its convex, obovate form, the very short setosity, the strongly

constricted rostrum, the anteriorly constricted, very coarsely punctured, transverse

prothorax, and the regularly seriato-granulate elytral interstices, the granular

elevations closely placed and extending from the base to the apex, the seriate

punctures fine, the second interstice with a conspicuous tubercle before the apex.

We are indebted to the authorities of the Dresden Museum for a specimen of

this species; it is labelled as having been obtained originally from Motschulsky.

There is a closely allied undescribed form from Cocos Island in the British Museum.

In its basally constricted rostrum this species approaches dA. panamensis, Faust,

from which it differs in its more oblong shape, the less constricted prothorax, and

very dissimilar elytral sculpture. Dr. Heller has been kind enough to compare the

single specimen received by us with the type in the Dresden Museum.

RHYPARONOTUS.

Rhyparonotus, Faust, Deutsche ent. Zeit. 1892, pp. 20, 33.

Ten species of this genus have been described, all from Colombia and Venezuela,

one only of which (&. scapha) is known to me by name. They appear to be rare

insects, the three forms now added from Costa Rica or Nicaragua being represented

in our collection by seven specimens. Ahyparonotus is closely allied to Anchonus,

but differs from it in having the anterior coxe separated, and from Cestophorus in the

relatively shorter scape to the antenne. The funiculus is 8-jointed, the eighth joint

large and closely articulated to the club. The scrobes are shallow behind. ‘The eyes

are flattened and almost smooth, and not easily seen.

§1. Rostrum not constricted at the base.

1. Rhyparonotus serripes, sp.n. (Tab. VI. fig. 17, ¢.)

Elongate-ovate, black, the antenne and tarsi partly rufescent, the surface coated with an earthy incrustation ;

the sete very short. Rostrum not constricted at the base, curved, a little shorter than the prothorax,

granulate, rugusely punctured to the tip, obsoletely, longitudinally sulcate; scape reaching the anterior

margin of the eye. Prothorax considerably longer than broad, somewhat rounded at the sides, gradually

widening from the base to before the middle, and then narrowed to the apex and feebly constricted ; the

surface granulate, except down the middle and along a sinuous space midway between this and the

margin. LElytra about twice as long as the prothorax, oblong-oval, flattened on the disc, abruptly

declivous behind, conjointly rounded at the apex ; seriate-punctate, the interstices 3, 5, and 7 (2, 4, 6 on

the apical declivity) interruptedly costate, each with a scattered series of rounded, setigerous tubercles,

which become more raised towards the tip, the tubercles smooth and shining at the summit. Ventral

segments 1, 2, and 5, and the metasternum also, coarsely rugose. Legs rough, the femora granulate, the

anterior and intermediate tibie sharply, and the posterior pair more finely, denticulate within. Anterior

cox rather widely separated.

Length 74-94, breadth 3-35 millim. (d¢.)

Hab. Costa Rica, Caché, Volcan de Irazu (fogers).

Three specimens, one of which is clean and immature. Separable from the

following species by the non-constricted rostrum, the coarsely rugose under surface,

the sharply denticulate inner edge of the tibie, &c.

RHYPARONOTUS. 91

§ 2. Rostrum constricted at the base.

2. Rhyparonotus vermiculatus, sp. n.

Elongate-ovate, narrow, black, the antenne and tarsi obscurely rufescent, the surface coated with an earthy

incrustation ; the sete extremely short, the femora with a few longer ones beneath. Rostrum strongly

constricted at the base, stout, curved, nearly as long as the prothorax, rugosely punctured and shallowly,

longitudinally sulcate; scape reaching the anterior margin of the eye. Prothorax much longer than

broad, widest at the middle, more narrowed in front than behind, constricted before the apex ; the surface

irregularly rugose, the rug: here and there confluent and forming sinuous or oblique ridges, and some-

times shallowly grooved down the middle. Elytra oblong-oval, about twice as long as the prothorax,

flattened on the disc, with the apex broadly produced and conjointly rounded (truncate as viewed from

above), the humeri rather prominent, the basal margin raised ; coarsely seriate-punctate, the interstices

2 and 4 subcarinate, 5 and 6 also a little raised, 2,4, 6 each with a row of prominent, rounded, setigerous

tubercles beyond the middle, the tubercles large on the apical declivity and represented by a scattered

series of minute shining granules on the anterior half. Ventral surface very sparsely, finely punctate.

Tibie finely denticulate on their inner edge. Anterior coxee somewhat widely separated.

Length 74-8, breadth 24-3 millim. (<¢.)

Hab. Costa Rica, Volcan de Irazu (Rogers), Volcan de Turrialba (Biolley).

Three specimens. Distinguishable by its narrow form, the strongly constricted

rostrum, the finely punctured ventral surface, and the extremely short sete of the upper

surface. The prothorax in one example has the vermiculate sculpture interrupted at

the middle by a narrow groove.

8. Rhyparonotus inermis, sp. n. (Tab. VI. fig. 18, 2.)

margin of the eye. Prothorax slightly longer than broad, gradually widening from the base to near the

apex and then abruptly narrowed and constricted ; the surface, except down the middle and along a

sinuous space on each side midway between this and the margin, sparsely granulate, with intermixed

sinuous ruge. Elytra oval, about twice as long as the prothorax, sharply margined at the base, the apex

broadly produced and conjointly rounded ; seriato-foveate, the interstices 2, 4, and 6 more or less costate,

2 sharply so on the apical declivity, each set with scattered rounded or oblong setigerous elevations,

Hab. Nicaracua, Chontales (Belt).

One specimen. Allied to FR. vermiculatus, but broader, with the rostrum more

curved, the prothorax shorter, less rugose, and widest before the middle, the second

elytral interstice much more raised towards the apex, the anterior coxe more

approximate, the tibie not denticulate on their inner edge, the sete on the upper

surface slightly longer.

Geobyrsa, Pascoe, Journ. Linn. Soc., Zool. xi. p. 450 (1872).

Anephilus, Faust, Deutsche ent. Zeit. 1892, pp. 20, 34.

Five species are known of this genus—one from Central America, three from San

Esteban, Venezuela (two of which I have seen), and one from the Island of Guadeloupe.

They are very like the narrower and more elongate Anchont, but are easily separable

therefrom by the 6-jointed funiculus* to the antennew. The funiculus is short,

gradually widening from the elongate second joint, joints 3-6 being transverse, and 6

almost as wide as the club, These insects are usually so coated with dirt that nothing

can be seen of the sculpture till they have been cleaned.

Elongate-obovate, nigro-piceous, setose, the sete clubbed and forming fascicles on the prothorax and on the

elytral tubercles. Rostrum curved, as long as the prothorax, coarsely seriate-punctate, the widened

apical portion short in the ¢, and rather long and cylindrical in the 9. Prothorax subcylindrical, much

longer than broad, a little narrowed in front and behind, slightly constricted before the middle, and

emarginate in the centre at the base; the entire surface closely, deeply, and very coarsely punctate, the

setee forming two fascicles at the apex and four in a transverse row about the middle. Elytra oblong-

ovate, convex, closely and coarsely seriato-punctate, the interstices very narrow, the alternate ones each

with a row of scattered setigerous tubercles.

Length 4-5, breadth 14-2 millim. (¢ 9.)

Hab. Guatemaua, El Tumbador (Champion); Nicaragua (Sallé), Chontales ! (Belt).

Very like A. simoni, Faust, from Venezuela (a typical example of which is before

me), but with the punctuation of the prothorax and elytra very coarse and foveiform,

the prothorax without a smoother space down the middle, the setigerous tubercles on

the elytra a little more prominent. Pascoe’s type is in a very dirty condition, and the

puncturing of the surface was not noticed by him. Four specimens have been received

by us.

Sect. Il. Eyes placed at the sides of the rostrum.

DIOPTROPHORUS.

Dioptrophorus, Faust, Deutsche ent. Zeit. 1892, pp. 20, 35.

This remarkable genus is peculiar to Mexico, Guatemala, and Cubay. ‘The type,

D. ocularis, was included by Boheman in Anchonus, though he noticed that the

coarsely facetted eyes were placed at the sides of the rostrum, instead of on the smooth

globular portion of the head, as in Anchonus and its allies. The males, as in

angusticolls, Chevr.

DIOPTROPHORUS. . 98

Anchonus, differ from the females in having the antenne inserted nearer the tip of the

rostrum, with the apical portion of the latter somewhat rounded at the sides. In

D. verrucosus, which is larger and more robust than any of its allies, the facets of the

eyes are flattened, while in the other species they are convex.

Not seen by Faust, nor contained in our collection, the numerous specimens received

under this name from Sallé being incorrectly identified, and belonging to the genus

Anchonus. D. ocularis, to judge from the description, must be very nearly allied to

D. simplex, but with the prothorax widening from the base to before the middle and

then suddenly narrowed ; it is not unlikely that they will prove to belong to the same

species.

less distinct, and in others they are more elongate. Length 4-5 millim.

3. Dioptrophorus fausti, sp. n. (Tab. VI. figg. 20, 204, 3.)

Elongate-ovate, rather depressed, black, the legs piceous, the antennz obscurely rufescent ; covered in part by

a greyish incrustation and with scattered minute ochreous scales, the legs with short hairs. Rostrum

stout, nearly as long as the prothorax, coarsely, very shallowly punctate. Prothorax a little longer than

broad, widest at the middle, narrowed anteriorly and slightly so posteriorly, constricted before the apex,

the hind angles somewhat obtuse; coarsely punctate, except along a depressed space down the middle

and a sinuous space on each side between this and the margin. Elytra nearly twice as long as the

prothorax, flattened on the disc to near the apex and then abruptly declivous ; coarsely seriato-punctate,

the alternate interstices with scattered, feeble, oblong elevations, the third and fifth each with a very

prominent tubercle at the commencement of the apical declivity.

conspicuous elevations on the elytra culminating in four very prominent rounded

tubercles before the abruptly sloping apical declivity. ‘The single specimen obtained

appears to be a female; and, if so, the antenne are inserted a little nearer the apex

than usual.

5. Dioptrophorus sharpi. (Tab. VI. figg. 22, ¢ ; 23, 2.)

Dioptrophorus sharpi, Faust, Deutsche ent. Zeit. 1892, pp. 36, 58°.

Hab. Guatemata 1, Totonicapam 8500 to 10,500 feet (Champion).

Found in profusion under the bark of pines at Totonicapam. This insect is very

like D. simplex, but differs from it in having the prothorax more uneven on the disc,

and the sides straighter behind, the posterior angles being subrectangular. Length

4-54 millim.

6. Dioptrophorus fahrei. (Tab. VI. fige. 24, 24a, 9.)

Dioptrophorus fahrei, Faust, Deutsche ent. Zeit. 1892, pp. 86, 59°.

Hab, GuatemAta}, Totonicapam 8500 to 10,500 feet (Champion).

If I have identified it correctly, three specimens only of this species are contained in

our collection. They are narrower than D. sharpi, with the prothorax a little longer,

more uneven, and constricted nearer the apex, so as to appear wider anteriorly, and

the elytral elevations more elongate. Length (3 2?) 42-5 millim.

§ 2. Eye-facets flattened.

7. Dioptrophorus verruciger, sp. n. (Tab. VI. figg. 25, 25 a.)

Elongate-ovate, robust, black, coated in great part with an earthy incrustation ; the setosity extremely short.

Rostrum very stout, shorter than the prothorax, constricted at the base, coarsely, closely punctate, and

obsoletely carinate down the middle; eyes comparatively large, not very prominent, the facets flattened.

DIOPTROPHORUS.—ITHAURA. 95

Prothorax much longer than broad, widest a little before the middle and obliquely narrowing thence to

the base and apex, constricted in front, the apex emarginate; the disc somewhat flattened, irregularly

carinate down the middle, and with a large, depressed, subtriangular space on either side towards the

apex, the depression followed by two angular prominences, the rest of the surface with coarse scattered

punctures and irregular ruge, the margins subtuberculate at the middle. Elytra oblong-ovate, much

wider than the prothorax, but at the base of nearly the same width, considerably produced at the apex ;

interruptedly seriate-punctate, the interstices with a scattered series of large, rounded, exceedingly

prominent tubercles, these becoming more elongate towards the base and there forming ridges on the

third and fifth. Legs stout.

‘Length 9, breadth 4 millim. (?9.)

Hab. Mexico, Sierra de Durango (Flohr).

One specimen. Larger, more robust, and more elongate than any of the other

known species of the genus, the elytra strongly nodose, the eye-facets flattened, instead

of convex. In general facies D. verruciger is very like Anchonus nodosus.

ITHAURA.

Ithaura, Pascoe, Journ. Linn. Soc., Zool. ix. p. 215, t. 6. figg. 2-2 a-c (1871) ; Ann. & Mag. Nat.

Hist. (5) vu. p. 808 (1681).

Head globose, smooth; rostrum constricted at the base, stout, feebly curved, the apical portion a little

widened, the scrobes deep, visible from above anteriorly, descending to beneath the eyes, and some-

what widely separated behind; eyes rounded, coarsely facetted, placed at the sides of the rostrum

behind: antenne inserted at about one-third from the apex of the rostrum, the funiculus 7-jointed,

joints 1 and 2 subequal in length, the others transverse, the scape reaching to about the middle of the

eyes, the club short-ovate and pubescent; buccal opening large, the oral organs visible; prosternum

much developed in front of the anterior coxe, slightly hollowed at the apex, with a transverse sulcus

near the anterior margin; pronotum extending backward over the mesonotum; anterior coxe very

narrowly separated; mesosternum extending forward in front of the intermediate cox, which are

narrowly separated; scutellum wanting; elytra connate, hollowed at the base, with the subangular

humeri embracing the hind angles of the prothorax, covering the apex of the abdomen, and without

membranous apical margin ; first and second ventral segments connate at the middle, the third and

fourth short, the sutures 2 and 3 deep and straight ; femora stout; tibie mucronate at the inner apical

angle, the anterior pair sharply so, and with a terminal claw arising from about the middle of the apical

margin ; third tarsal joint a little widened, entire at the apex, the fourth joint articulated to it in a

cavity on the upperside; claws slender, simple, divergent; body elongate-oval, apterous, coated with

a hard permanent, glossy incrustation.

This remarkable genus was referred by Pascoe somewhat doubtfully to the

Calandrine, but it seems to me to be very closely related to Dioptrophorus, of

the group Anchonina. The two species described by him were from Colombia

and Parana respectively, and two others are now added from our region. Typhlo-

glynma, Dury *, also referred to the Calandrine by its describer, including a single

N.-American species, is a nearly allied form. The above-mentioned characters, taken

from the Central-American insects, will supplement Pascoe’s description.

In Ithaura there are well-developed eyes at the sides of the rostrum (as in

Dioptrophorus and Theognete), the scrobes are somewhat distant beneath, the first

* Journ. Cincinnati Soc. Nat. Hist. xix. pp. 243, 244, fig. (March 1901),

96 RHYNCHOPHORA‘

and second ventral segments are separated laterally, and there is no visible scutellum* ;

whereas in Typhloglymma the eyes are stated to be wanting, the scrobes are subcon-

tiguous beneath, the first and second ventral segments are completely fused, and there

is a small visible scutellum. From Dioptrophorus the present genus differs in having

the prosternum more developed in front of the anterior coxe, the pronotum extending

back over the mesonotum (the elytra being hollowed at the base for its reception), &c. ;

the entire surface, too, is coated with a permanent, smooth, glossy incrustation. The

two species here described were found at a high elevation in Guatemala and Mexico

respectively, one of them under the bark of fallen pines. The unique type of Typhlo-

glymma was taken out of debris from a cavity in a decayed oak, in which was a nest

of Formica pennsylvanica.

1. Ithaura pinicola, sp.n. (Tab. VI. figg. 26, 26a, 3; 27, 9.)

Moderately convex, grey or brownish-grey, the antenne and tarsi obscurely rufescent ; the upper surface very

coarsely and somewhat closely punctate, with the interspaces smooth, the punctures each bearing one or

two extremely minute golden scales ; the legs with a few short hairs, and some longer and more bristly

ones on the lower edge of the femora and on the inner edge of the tibie. Rostrum strongly constricted at

the base, much shorter than the prothorax in both sexes, smoother in the Q than in the g. Prothorax

longer than broad, feebly rounded at the sides, narrowed in front and slightly so behind, strongly

constricted at the sides before the apex, the groove not extending across the dorsal surface, the disc

finely carinate down the middle; the punctures large and rounded. Elytra oblong-oval, a little wider

and nearly one-half longer than the prothorax, conjointly rounded at the apex ; the punctures large, oval,

and arranged in nine regular rows ; the interstices flat in some specimens and distinctly convex in others.

Beneath very coarsely punctate, except the third and fourth ventral segments, which are smooth, the

first segment flattened in the middle in the ¢. Tibie very minutely denticulate on the inner edge ;

the anterior pair with a fine sharp tooth before the middle in the ¢.

Length 43-6, breadth 2-2} millim. (¢ @.)

Hab. Guatemata, Totonicapam 8,500-10,500 feet (Champvon).

Ten specimens, found under the bark of decaying pines. The sculpture of the

upper surface of this species is exactly like that of Typhloglymma puteolatum, from

Ohio, as figured by Dury. The much smaller size, the very coarsely punctured

thorax, &c., separate it from J. strangulata, the type of the genus.

2. Ithaura exarata, sp.n. (Tab. VI. fig. 28, 3.)

Elongate-ovate, convex, greyish-olivaceous, the antenne and tarsi rufescent ; the punctures of the upper and

under surfaces each bearing a minute, piliform, golden scale ; the legs with short hairs. Rostrum feebly

constricted at the base, a little more than one-half the length of the prothorax, coarsely, closely punctate.

Prothorax longer than broad, distinctly rounded at the sides, narrower in front than at the base, the

anterior constriction just visible from above ; the surface somewhat closely impressed with large rounded

punctures separated by smooth, flat interspaces, and with indications of a raised line down the middle.

Elytra oval, nearly one-half longer than the prothorax, finely seriate-punctate, the interstices strongly

convex, of the same width as the spaces between them, and each with a series of very fine scattered

punctures. Beneath extremely coarsely punctate, except the anterior portion of the mesosternum and

the third and fourth ventral segments, which are smooth, the first segment flattened in the middle.

Length 54, breadth 24 millim. (<¢.)

* Pascoe states that there is a small scutellum present; but this is a mistake, as shown by his figure.

ITHAURA.—THEOGNETE. . 97

Hab. Mexico, San Antonio de Arriba (Salié).

One specimen. Differs from J. pinicola in the more convex shape, the feebly

constricted, shorter rostrum, and the sulcate, finely seriate-punctate elytra. The

anterior tibia are without a median tooth.

THEOGNETE, gen. nov.

Antenne with the funiculus 7-jointed, joints 3-7 transverse and gradually widening, 7 closely articulated

to the club, the latter short-ovate, pointed at the tip, the first joint shining and the others dull and

pubescent; head globose, smooth; rostrum stout, constricted at the base, slightly widened in its apical

half, the scrobes deep, lateral, descending to beneath the eyes, the anterior opening just visible from

above; the eyes placed at the sides of the rostrum behind, oval, coarsely facetted ; prothorax trans-

versely convex, with a transverse sulcus before the anterior margin beneath, visible at the sides above, the

prosternum very short; anterior cox somewhat widely separated; intermediate coxe widely separated,

the mesosternum transversely sulcate between them; metasternum extremely short; posterior cox

inserted near the outer margin of the body, and narrowly separated from the intermediate pair; scutelium

absent ; elytra connate, gibbous, cordiform ; ventral segments 1, 2, and 5 subequal in length, 3 and 4

exceedingly short, 1 and 2 connate, the first suture sinuous; legs short and stout; tibie slightly sinuate

within, not dilated at the tip, mucronate at the inner apical angle, and armed with a curved claw at

the apex, the lower apical margin furnished with several fine tecth ; tarsi very short, feebly developed,

sparsely pilose beneath, the third joint bilobed, the claws extremely minute, free.

The single species referred to this genus has somewhat the facies of a Liosomus or a

minute Liparus. It is a very remarkable form, wholly different in appearance from

Dioptrophorus, to which Theognete is nearly related. ‘The tarsi are very small and

short, compared with the powerful femora and tibie. ‘The anterior coxe are a little

more widely separated than in any of its nearest allies.

1. Theognete levis, sp.n. (Tab. VI. figg. 29, 29 a, 6.)

Obovate, very convex, shining, black, the tarsi and the antenne in part rufescent; the prothorax and elytra

with a few, widely scattered, appressed, long, coarse, piliform, flavescent scales ; the legs with similarly-

coloured short hairs. Rostrum nearly as long as the prothorax, coarsely and closely punctured ; the

-antenne inserted at about the middle. Prothorax as long as broad, constricted at the apex and narrowed

‘behind, the sides slightly sinuous in one specimen; the surface smooth, with minute scattered squami-

gerous punctures. Elytra short, gibbous, with the apices produced and conjointly rounded, about

one-half longer, and much wider than the prothorax, smooth, each with a longitudinal groove near the

suture below the base, in which traces of seriate punctures are visible. Beneath smooth. Fifth ventral

segment obliquely sloping from about the middle to the apex, the anterior portion flattened and with a_

transverse-oval depression in the. middle, the posterior portion with a transverse depression on each side

in front and another in the centre behind.

Length 3, breadth 13 millim.

Hab. Mexico, Sierra de Durango (Flohr) ; Guaremata, Cerro Zunil (Champion).

One specimen from each locality, their sex not ascertained. The Mexican individual

is a little more robust, and has stouter legs, and coarser scattered scales, than the

Guatemalan insect.

Group CLEONINA.

This group includes Cleonus, Dinocleus, Lirus, and Lleomus, the first two not

extending south of Mexico. Larinus is altogether absent, possibly owing to the

limited number of indigenous Carduace, not only from our region, but from the whole

of America.

A genus including a large number of species, the majority of which inhabit the

Palearctic region. Capt. Casey recognizes twenty-four North-American forms, two of

these entering Mexico, whence five are now known. ‘The Palearctic Cleont have been

grouped under numerous subgenera; the Mexican forms may for the present be

referred to two—Apleurus and Cleonidius. The prothoracic vibrisse are long in

C. fossus, C. pulvereus, and C. aztecus, and quite short in C. boucardi and C. lobigerinus.

In C. aztecus the tarsal claws are free.

The type ef this insect, which is not labelled with any definite locality, is contained

in our collection, and we have six others from Hoge or Sallé. C. fossus is probably

nothing more than a southern form of C. pulvereus, Lec.; but may be separated by its

more robust build, stouter rostrum, and coarser sculpture. The largest specimens,

including the type, are considerably broader than any of the numerous North-American

or Mexican C. pulvereus before me. The rostrum is sometimes obsoletely carinate.

3. Cleonus aztecus, sp.n. (Tab. VII. fig. 2.)

Subovate, convex, robust, rather shining, black, thickly clothed with cinereous pubescence ;. the prothorax

with the apex and a broad space down the middle, and the elytra each with two fascize on the disc,

almost glabrous. Rostrum short, very stout, dilated at the tip, flattened above, coarsely punctured, with

the interspaces densely, minutely punctate, obsoletely carinate. Prothorax broader than long, the sides

(as seen from above) subparallel from the base to near the apex, and then abruptly and obliquely

converging; the surface uneven, coarsely, irregularly punctured, with the interspaces densely, minutely

punctate; the anterior margin simply sinuate opposite the eyes, the vibrissee long. Elytra moderately

long, oval, widest about the middle ; coarsely seriate-punctate, the interstices narrow, almost smooth.

3, 5 and 7 costate, 5 not callose towards the apex. Beneath somewhat coarsely punctate; ventral

segments 1 and 2 broadly depressed down the middle. Tarsi with small spongy-pubescent pads beneath ;

claws free.

Length 83-94, breadth 4-43 millim. (¢.)

Hab. Mexico, Refugio in Durango (Hége), Sierra de Durango (Lohr).

Two specimens. This insect differs from the other Mexican forms in having the

tarsal claws free and the alternate elytral interstices costate. In general structure it

is not unlike the European C. quadrivittatus, Zoubk., which also has free tarsal claws.

Three specimens, probably belonging to this species. The two from Villa Lerdo

are almost uniformly clothed with cinereous pubescence, the sides of the prothorax

only being bordered with a whitish vitta. The one from Mexico city is very like a

Californian C. lobigerinus, sent me by Mr. Wickham. All have prominent ocular

2. Dinocleus dentatus, sp. n. (Tab. VII. fig. 5.)

Elongate-ovate, moderately robust, somewhat shining, black, the minute spines along the apical margin of the

tibiee ochreous ; above somewhat sparingly clothed with cinereous pubescence, which does not hide the

punctures, and is here and there variegated with whitish, and denuded in places, so as to give a mottled

appearance to the elytra, the prothorax with a sinuous whitish vitta on each side (leaving a broad, sharply

defined, partially denuded, dark space down the middle of the disc); the under surface and legs somewhat

densely clothed with whitish pubescence, with small, scattered, partially denuded spots, these becoming

larger and more conspicuous on the first four ventral segments. Rostrum very stout, widened at the tip,

coarsely punctate, the interspaces closely and minutely punctured, not carinate; second joint of the

funiculus much shorter than the first and longer than the third. Prothorax (along the median line)

about as long as broad, conspicuously tuberculate at the sides a little before the apex, so as to appear

abruptly narrowed and constricted in front, the sides almost straight from the tubercle to the base; the

surface uneven, strongly depressed in the middle at the base, irregularly foveato-punctate, the interspaces

closely, minutely punctate; the anterior margin simply sinuate opposite the eyes and furnished with long

vibrisse. Elytra elongate, much wider than the prothorax, a little rounded at the sides along the median

third, subparallel towards the base, the apices considerably produced, the humeri rounded ; seriate-

punctate, the punctures here and there larger and foveiform, the interspaces flat, rugulose, and each with

a scattered series of minute granules. Prosternum with the tubercle in front of each anterior coxa small,

completely covered by the white pubescence.

Length 14, breadth 53 millim. ( 2.)

One specimen. In Captain Casey’s arrangement of the species (Ann. N. York Acad.

members of which it differs in the sparser and more mottled vestiture of the upper

surface (which is not dense enough to hide the larger punctures) and the conspicuous

denuded spots on the ventral surface. The narrower, less robust form, the more

Scaphomorphus, Motschulsky, Bull. Acad. St. Pétersb. ii. p. 541 (1860).

A genus of almost universal distribution. In nine out of the twenty-three species *

here enumerated from within our limits, the wings are rudimentary or absent, the

elytra being particularly hard in these forms. ‘They all have the scutellum vertical

or depressed, and often quite invisible when the prothorax is closed up to the elytra ;

and the eyes oval in shape. J. basilaris, L. mexicanus, &c., vary enormously in

size, with a corresponding variation in the development of the rostrum, which is almost

always longer in the female than in the male (very much longer in L. fimbriolatus

and L. toltecus), and antenne, the latter being usually inserted nearer the tip of the

rostrum in the males. The sculpture, too, is somewhat unstable, as is also the relative

length of the basal joints of the funiculus and the prolongation or otherwise of the

apices of the elytra. The members of this genus, as is well known, are often coated

with a dense pollinose secretion, which is said to be renewable during the life of the

insect ¢, completely covering the sculpture and pubescence: the amount of pubescence

seems to be variable (at least in several of the species), some of that visible in fresh

specimens being afterwards lost; and the presence of a condensed submarginal vitta,

unless accompanied by a corresponding groove, is an inconstant character. ‘The males

of most of the Central-American forms have the basal one or two segments of the

abdomen more or less sulcate down the middle. No fewer than 233 species of Lirus

are enumerated in the “Munich Catalogue,” but a number of these names must be

synonyms.

The various forms captured by myself in Guatemala or Panama were mostly obtained

Cylindrical, black, shining, cinereo-pubescent, the pubescence in fresh specimens mottled on the elytra and

forming sinuous lines on the prothorax. Head and rostrum closely, minutely punctate, with coarser

punctures intermixed, the head foveate between the eyes; rostrum( 3) stout, moderately curved, about

as long as the prothorax, longitudinally sulcate between the points of insertion of the antenne, a little

longer inthe @. Prothorax subconical, slightly rounded at the sides posteriorly, with a deep rounded

depression in the middle at the base; the surface closely, minutely punctate, with coarse punctures

intermixed. Elytra elongate, obtuse at the apex, compressed laterally at the base, the scutellar region

depressed; seriate-punctate, the interstices flat and very finely rugulose. Anterior femora acutely

dentate. First or first and second ventral segments sulcate down the middle in the g¢. Body winged.

(Champion).

Apparently the commonest species of the genus in Central America, and readily

identified by the acutely dentate anterior femora and the comparatively short curved

rostrum, which is a little longer in the female than in the male. The larger punctures

on the prothorax and elytra are sometimes quite fine. A pair from Duefias are more

thickly pubescent than the rest, but this is probably due to their fresh condition, the

longer hairs being easily abraded; and two of the smallest females, from Chiriqui

(perhaps specifically distinct), have the rostrum much more slender than usual and the

basal constriction of the elytra not apparent. About eighty specimens have been seen,

varying greatly in size and in the amount of pubescence on the surface. Several

South-American Liat have dentate femora, but our insect seems to be different from

all those described *. |

2. Lixus cavicollis, sp. n.

Lizxus cavicollis, Chevr. in litt.

Elongate, robust, subfusiform, moderately shining, black, clothed with a very short, sparse, cinereous pubescence,

which is often mottled on the elytra; the legs and under surface with intermixed longer hairs. Head

excessively minutely punctate, with intermixed slightly coarser punctures, foveate between the eyes;

rostrum shining, very stout, about as long as the prothorax in both sexes, longitudinally sulcate between

the points of insertion of the antenna, the punctuation a little sparser than that of the head. Prothorax

convex, conical, about as long as broad, strongly bisinuate at the base, the median lobe almost covering

the vertical scutellum ; densely, minutely punctate, with scattered, intermixed, coarser punctures, the

basal impression large, rounded, and very deep; anterior margin with a short obtuse tooth opposite the

lower angle of the eyes. Elytra very elongate, much wider than the prothorax, abruptly and sinuously

L. cavicollis is quoted by Boheman as synonymous with Z. fimbriolatus, but it differs

from that species in its broader and more robust form, the scantier pubescence (which

is not all concentrated laterally), the very stout, comparatively short rostrum in both

sexes, and the larger depression at the base of the prothorax. ‘This is a common

insect in Mexico and Guatemala, whence we possess a long series, varying only in size.

baro, Cordova (Hége), Temax in N. Yucatan (Gawmer); GUATEMALA, Las Mercedes;

Duefias (Champion).

In the typical form of this insect the prothorax and elytra have a submarginal vitta

of condensed whitish pubescence, a character also to be found in certain specimens of

L. macer (as noted by Leconte); but this is frequently obsolete, and in our series of

twenty-eight examples from Mexico or Guatemala four only possess this peculiarity.

L. fimbriolatus may be identified by the dissimilarity in the length of the rostrum in

the two sexes, it being about twice the length of the prothorax and strongly curved

in the female, and shorter and moderately curved in the male. The first and second

ventral segments are more or less sulcate down the middle in the male. The rostrum

is slightly widened at the tip. We are indebted to Mr. Wickham for specimens of

L. macer from Ulinois and Iowa, with which our smallest examples agree. In s1X

out of the seven males from Duefias the pubescence is longer and more abundant

than usual, but this is probably due to their fresh condition. Length varying from

15-23 millim.

4. Lixus inermis, sp. n.

Elongate, cylindrical, shining, black, the antenne partly rufescent; finely cinereo-pubescent, the pubescence

in some specimens condensed into a narrow more or less distinct submarginal vitta. Head and rostrum

closely, minutely punctate, with intermixed coarser punctures, the head foveate between the eyes;

rostrum moderately stout, in the ¢ about as long as the prothorax and moderately curved, in the

9 slightly longer and strongly curved. Prothorax about as long as broad, subconical, strongly bisinuate

at the base; densely, minutely punctate, with intermixed coarser punctures, the basal depression rounded

and very deep. Elytra very little wider than the prothorax, subparallel for three-fourths of their length;

more or less acuminate at the apex, the common basal depression broad and shallow ; seriate-punctate,

the interstices flat and rugulosely punctate. First and second ventral segments shallowly sulcate down

the middle in the g. Body winged.

Length 103-15, breadth 3-4 millim. (d Q.)

Hab. Mexico, Toxpam in Vera Cruz (Sallé).

Seven specimens, three of which are immature. This species may be known from

L. cavicollis by its narrower, cylindrical shape (the elytra being scarcely wider than

the prothorax) and the more slender rostrum ; and from L. jimbriolatus by the shorter

rostrum in both sexes, that of the female being very little Jonger than that of the male,

as well as by its cylindrical form, smaller size, and less robust build. The unarmed

anterior femora and the acuminate elytra separate L. inermis from L. dentipes, which

is very like it in general facies; and the subparallel and less acuminate elytra from

LL. subcaudatus.

5, Lixus rugulirostris, sp. n.

Very elongate, cylindrical, shining, black, the antenne partly rufescent; finely cinereo-pubescent, in one

specimen with a well-defined submarginal white vitta. Head and rostrum densely, rugulosely punctate ;

the latter smoother at the tip, about as long as the prothorax, comparatively slender, and feebly curved.

Prothorax as long as or longer than broad, conical, densely, minutely punctate, with intermixed coarser

punctures, the basal depression small and shallow. Elytra very elongate, a little wider than the prothorax,

subparallel for three-fourths of their length, the apices slightly dehiscent and acuminate, the common

basal depression shallow ; seriate-punctate, the interstices flat, finely rugulose. First ventral segment

unimpressed. Body winged.

Length 123-154, breadth 3-32 millim. ( 9.)

Hab. Mexico, Puebla (Sallé), Amula (H. H. Smith).

Three specimens, probably all females: the one from Amula has a white submarginal

vitta, the prothorax longer than broad, and the rostrum sparsely punctured towards the

tip; the two from Puebla, which are covered with efflorescence, have the rostrum

densely rugulose to near the apex, and the elytra without trace of a submarginal vitta.

They possess in common, however, a very shallow depression at the base of the pro-

thorax, a character separating them from the nearly allied LZ. inermis. The rostrum

is comparatively slender. "

6. Lixus toltecus, sp. n.

Very elongate, narrow, cylindrical, shining, black, the antenne partly rufescent; finely cinereo-pubescent, the

pubescence mottled on the elytra, and with a condensed whitish submarginal vitta on the prothorax and

towards the apex of the elytra. Head shallowly foveate between the eyes, in the ¢ closely punctate,

with coarser punctures intermixed, in the 2 sparsely punctured ; rostrum in the ¢ moderately stout,

about as long as the prothorax, feebly curved, and closely, longitudinally rugulose almost to the tip, in

the 2 slender, distinctly longer than the prothorax, strongly curved, sparsely punctured from the base

to near the middle and almost smooth thence to the apex ; antenne in the ¢ inserted considerably before,

and in the 2 a little behind, the middle of the rostrum, joint 2 of the funiculus slightly shorter than 1

in both sexes. Prothorax convex, rather broader than long, subconical, strongly bisinuate at the base ;

closely, minutely punctate, with intermixed coarser punctures, the basal depression small and extending

forward. Llytra very elongate, of the same width as the base of the prothorax, subparallel for two-thirds

of their length, somewhat acuminate at the apex, the common basal depression shallow ; seriate-punctate,

the interstices flat and finely rugulose. First ventral segment unimpressed in both sexes. Body winged.

Length 93-11, breadth 23-25% millim. (¢ 2.)

Hab. Mexico, Puebla (Sal/é), Atlixco in Puebla (Hége).

Two males and two females. In this small species the sexual difference in the form

of the rostrum is almost as strongly marked as in L. fimbriolatus, that of the female

being slender, moderately long, strongly curved, and almost smooth beyond the middle.

In general shape L. toltecus resembles L. nigrinus, which, however, is not a very nearly

allied form.

impression before the base. ‘The rostrum of the female is slender, feebly curved, and

a little longer than the prothorax, that of the male being stouter and slightly shorter.

In the two specimens ( ¢ ) from the Sturm collection the second joint of the funiculus

is longer than the first, and this is the case in nearly all our other examples, including

the six from Guatemala; the second joint, however, seems to vary in length in this

species, irrespective of sex. The first ventral segment is unimpressed in both sexes.

The Guatemalan specimens have the submarginal vitta of the elytra almost obliterated,

except at the apex. Length 10-16, breadth 25-45 millim.

This species is apparently not rare in the elevated districts of Central and Western

Mexico, whence we have received twenty-one specimens. It has the prothorax broadly

flattened or depressed on the disc, and the elytra flattened on the disc towards the

base. The pubescence of the upper surface is cinereous, and slightly mottled in

places, being sufficiently condensed at the sides of the prothorax to form vitte. The

rostrum is moderately stout, barely as long as the prothorax in the ¢g, and slightly

longer in the @. The first ventral segment is faintly depressed down the middle in

collection, correctly identified. The pubescence of the upper surface is cinereous and

more or less mottled, it being longer at the sides of the prothorax and beneath. The

rostrum of the male is moderately stout and barely as long as the prothorax, that of

the female being a little longer and more slender. ‘The prothorax is subconical, very

densely; minutely punctate, with scattered, intermixed, coarser punctures; the basal

impression is large and deep. ‘The elytra are rather convex, broader than the

prothorax, but of the same width at the base, moderately long, somewhat rapidly

narrowing from about the middle, with the apices slightly produced; the depression

behind the scutellum is deep. The first ventral segment is depressed along the centre

in the male.

Numerous examples, differing from others from Iowa sent me by Mr. Wickham in

having the apices of the elytra subcaudate—a character, however, that is not constant.

may be distinguished by its narrower, more or less bowed shape (viewed in profile), the

very shining, smoother upper and under surfaces, the more slender rostrum (especially

noticeable in the females), and the strongly caudate elytra; the last-mentioned

character, however, is inconstant, the larger specimens having the apices no more

23. Lixus apterus, sp.n. (Tab. VII. figg. 15, 15a, ?.)

Elongate-obovate, black, shining, sparsely and very finely cinereo-pubescent, the pubescence closer on the

depressed sulci of the elytra. Head foveate between the eyes, closely, finely punctate, with coarser

punctures intermixed ; rostrum ( ¢ ) moderately curved, very stout, nearly as long as the prothorax, finely

broad, strongly bisinuate at the base; densely, rugulosely punctate, with coarser punctures intermixed,

more or less sulcate towards the base, the basal depression transverse or triangular, moderately large.

Elytra convex, a little wider than the prothorax, and widening to far beyond the middle, conjointly

rounded at the apex and separately so at the base, compressed laterally below the shoulders; seriate-

Hab. Costa Rica (Sallé, Van Patten), Caché, Rio Sucio, Irazu (Rogers), Guaitil de

Pirris, Reventazon, Tierra Blanca, Sarapiqui, Vara Blanca (Biodley).

Apparently a common insect in Costa Rica, and easily distinguishable by the some-

what inflated, sulcate elytra, the interstices of which are strongly convex. L. rojasi,

LIXUS.—STERNECHUS. 113

Jekel (=vittatus, Jekel, olim), from Venezuela, and L. sulcatus, Kirsch, from Colombia,

are allied forms: the first-mentioned has the alternate elytral interstices depressed, the

eyes more transverse, and the anterior femora dentate; the other has the first elytral

stria flattened and very broad, the anterior femora obtusely angulate, &c.

Ileomus, Schonherr, Gen. Cure. iii. p. 145; Lacordaire, Gen. Col. vi. p. 440.

A genus scarcely separable from Lixus, and including a few Tropical-American forms,

Cayo, Belize (Blancaneaux); GuatemaLa, El Reposo, Teleman, Panzos (Champion) ;

Nicaragua, Chontales (Belt, Janson); Panama, Bugaba (Champton).

We possess a long series of this insect, which is very like the South-American

I. mucoreus (Linn.), and perhaps not really distinct from it. The females have a much

more elongate rostrum than the males, and the latter have the first ventral segment

depressed down the middle. The anterior and intermediate femora are dentate.

Group STERNECHINA.

Hylobiides, groupe II. Sternéchides, Lacordaire.

This group includes a single genus, Sternechus, Schonh. (= Tylomus, Schénh.), which

Lacordaire refers without hesitation to the Hylobiina, the subconnate tarsal claws

notwithstanding, a character common to most of the Cleonina, near which it seems

best placed. The species are very like the Australian Gonipterina.

Sternechus and Tylomus are connected by intermediate forms, there being a gradual

transition from one to the other in the armature of the tibie, and also in the relative

length &c. of the antenne. 4. drevicollis greatly resembles the Cryptorrhynchid-genus

Chalcodermus, some species of which have an angular prominence at the sides of the

elytra. The sexes, except in S. pollinosus, are not separable by external characters.

The lateral prominences of the elytra vary in form according to the species, and

gradually become obsolete, as in S. bicinctus. The genus is confined to Tropical

America, ranging as far north as Mexico, and extending to the Antillean Islands.

The Central-American species may be arranged under four main groups by the

armature of the legs, thus :—

serrulate, or simply setose along their inner edge, the latter also with a sub-

median tooth or angular dilatation . 2. - 6 ee + ew ee es Species 1-5.

Not rare in Mexico, and varying a good deal in the elytral sculpture, the glabrous

elevations on the alternate interstices gradually becoming more and more broken

Broad-ovate, robust, black, shining; the prothorax, except upon two transverse spaces on the disc and two

spots on each side, and the alternate flattened elytral interstices, thickly clothed with fine cinereous or

flavo-cinereous pubescence; the under surface and legs very sparsely pubescent. Head finely punctate,

sulcate and foveate between the eyes, which are rather narrowly separated ; rostrum very stout, short,

closely, irregularly punctate, in some specimens carinate towards the base. Prothorax transverse, rounded

Hight specimens. Very hke the Brazilian S. guerint, Boh., from which it differs in

having each of the alternate elytral interstices costate (in 8. guerint the seventh is raised

at the base only, and the ninth scarcely at all). SS. continwus is perhaps nothing more

this and the apex, and also with a sharp tooth at the inner apical angle.

Length 8, breadth 47-43 millim.

Hab. Guatemata, Panima (Champion), Coban (Conradt).

Two specimens, both from Vera Paz. In this species, as in S. nitédus, the rostrum

surface closely punctate, the punctuation becoming coarser towards the sides, with finer punctures inter-

mixed. Elytra subcordate, convex, conjointly rounded at the apex, the humeri rounded and moderately

swollen, the infra-humeral prominence triangular; seriate-punctate, the interspaces as wide as the

We have received nine specimens of this species from within our limits, these

agreeing very nearly with the only one I have seen from Cayenne. Distinguishable by

the rugose upper surface and legs, the sparse piliform squamosity, the very prominent,

120 RHYNCHOPHORA.

Oblong-ovate, piceous or rufo-piceous, darker beneath ; the upper surface with scattered, piliform, appressed,

whitish or ochreous scales, and with small patches of coarser, broader, similarly-coloured scales on the

disc, sides, and base of the prothorax (the two small spots on the dise and one in front of the scutellum

being the most distinct), on the scutellum, and at the apex of the elytra, and two oblique irregular fascie of

coarse scales on the disc of each of the latter (the anterior one entirely ochreous, the other ochreous, becoming

whitish towards the suture); the under surface thickly clothed with coarse, oval, whitish or ochreous

scales, the legs with piliform scales. Head and rostrum rugosely punctured, the antenne inserted at the

middle of the latter in the ¢, and ata little behind the middle in the 9. Prothorax slightly broader

than long, abruptly constricted and much narrowed in front, the sides feebly sinuate before the base, the

hind angles acute and directed outwards ; the surface densely, coarsely punctate, the narrow interspaces

subgranulate, the disc with an abbreviated median carina. Elytra flattened on the disc, coarsely

punctate-striate, the interstices rugulose and rather coarsely granulate, the alternate ones more or less

costate. Beneath coarsely, closely punctate, the first ventral segment in the g depressed along the

middle and more sparsely punctured.

Length 73 millim. (¢ 2.)

Hab. Norta America!?35, Lake Superior to Georgia*.— Mexico, Omilteme in

The female scarcely differs from others before me from Boston, U.S.A., but the

male has a more coarsely sculptured prothorax and coarsely granulate elytra.

Group LISTRODERINA.

The affinities of this group, as shown by the Australian genus Desiantha, Pasc., seem

to me to be with the Erirrhina (Hydronomides), and not with the Hyperina, amongst

which it is placed by all North-American writers.

LISTRONOTUS.

Listronotus, Jekel, Ann. Soc. Ent. Fr. 1864, p. 566; Leconte, Proc. Am. Phil. Soc. xv. p. 127.

The North-American species referred to Listroderes by Gyllenhal were separated by

Jekel from that genus under the name Listronotus, and this course has been followed

by Leconte, the chief difference being the posteriorly evanescent scrobes in the South-

American forms.

In L. bagotformis and its allies the first and second ventral segments are connate at

the middle, and the scrobes are deep throughout.

1. Listronotus bagoiformis, sp.n. (Tab. VIII. figg. 1, 1a, ¢.)

Elongate-ovate, narrow, somewhat depressed, black, the antennz and tarsi partly ferruginous ; thickly clothed

with rather large rounded scales, which on the upper surface are mostly of a pale brown colour, variegated

with whitish and fuscous, the darker mottling being most distinct on the dorsal portion of the elytra; the

elytra with a row of scattered, fine, decumbent sete on each interstice, the rest of the surface and the legs

also with scattered hairs. Head and rostrum closely, finely punctate; the rostrum stout, shorter than

the prothorax, very faintly carinate towards the tip; the front shallowly foveate; second joint of the

funiculus much longer than the first. Prothorax a little broader than long, slightly rounded at the sides,

as well as at the base, about equally narrowed in front and behind, the surface densely, rugulosely

punctate. Elytra moderately elongate, nearly onc-half wider than the prothorax, very gradually narrowing

obliquely subtruncate ; finely punctate-striate, the interstices rugulose and almost flat, the fifth feebly |

callose towards the apex. Beneath closely punctate, with scattered intermixed coarser punctures. Venter

strongly depressed down the middle of the first two segments in the ¢.

Eleven specimens. Very like the North-American LZ. latiwsculus (Boh.), but with

longer sete on the elytra (these not being at all clubbed) and the seriate punctures

on the latter not so coarse.

2. Listronotus —— ?

Hab. Mexico, Vera Cruz (Hége).

A single female specimen, too worn for description. This insect is very like

L. bagoiformis, but differs from it in having the rostrum distinctly carinate, the elytra

piceous in colour, very coarsely seriate-punctate, with the interstices convex and sparsely

rugulose, the under surface more coarsely punctured, and the tibie ferruginous.

1. Hyperodes hirtella.

Macrops hirtelius, Dietz, Trans. Am. Ent. Soc. xvi. p. 46 (1889) '.

Elongate-ovate, shining; varying in colour from black to ferruginous, pale specimens sometimes having a

common black patch on the elytra or a longitudinal black vitta on the disc of each of them; the upper

surface with scattered, coarse, erect, blunt sete, and when fresh clothed with large, rounded, loosely

attached griseous or brownish scales, which tend to form vitte on the prothorax and irregular spots on

the elytra; the legs setose. Head and rostrum densely, rugulosely punctate; the latter short and stout,

dilated at the apex, shallowly foveate at the base, and more or less distinctly tricarinate ; joints 1 and 2

of the funiculus subequal in length, 1 stouter than 2. Prothorax transverse, rounded at the sides,

coarsely, densely punctate. Elytra one-half wider than the prothorax, slightly hollowed at the base,

subparallel to near the middle, and a little produced at the tip; coarsely punctate-striate, the punctures

closely placed, the interstices somewhat convex, shining, not wider than the strie, and each with a row

“122 RHYNCHOPHORA.

Jalapa (Hége); Guatremata, San Gerdénimo (Champion); Nicaragua, Chontales

(Janson); Panama (Mus. G. & S.).

The twelve specimens obtained by us agree so closely with the description of

M. hirtellus that there can be little doubt as to their identity; the three from

Chontales, however, have the elytral sete almost entirely confined to the alternate

interstices, as in 1. sparsa &c.

2. Hyperodes testaceipes, sp. n. (Tab. VIII. figg. 2, 2a.)

Elongate-ovate, somewhat depressed, slightly shining; piceous, the antennew, the anterior margin of the

prothorax, and the legs ferruginous or testaceous ; the upper surface with scattered, erect, blunt setze and

minute, appressed, piliform scales, and when fresh thickly clothed with large rounded pallid scales ; the legs

setose. Head and rostrum rugulose; the latter short and stout, dilated at the apex, shallowly foveate at

the base, and tricarinate ; joints 1 and 2 of the funiculus subequal in length, 1 stouter than 2. Prothorax

transverse, rounded at the sides, densely, finely punctate, and sometimes with indications of a faintly

raised, smooth, median line. Elytra one-half wider than the prothorax, subparallel to near the middle,

slightly hollowed at the base, and a little produced at the tip; rather coarsely punctate-striate, the

punctures closely placed, the interstices about as wide as the striw, feebly convex, rugulosely punctate,

the alternate ones each with a scattered row of sets, the minute piliform scales conspicuous when the

larger ones are abraded.

Length 34-34 millim.

Hab. Mexico, San Juan Bautista in Tabasco (Hoge).

Three specimens, their sex not ascertained. Very like H. hirted/a, but differing from

it in the finely punctured prothorax, the less coarsely punctured striz, and the rugulose

elytral interstices, the alternate ones only with a scattered row of sete. ‘The minute

piliform scales are conspicuous when the larger ones are removed.

3. Hyperodes angustata, sp. n. (Tab. VIII. figg. 3, 3 a.)

Elongate, narrow, rufo-piceous, the elytra mottled with black; the upper surface clothed with scattered,

erect, blunt sets, and small, narrow, appressed, ochreous scales, without larger rounded scales ; the legs

setose. Head finely punctate; rostrum short and stout, widened at the tip, rugosely punctate, faintly

foveate at the base, without distinct carina above; joints 1 and 2 of the funiculus subequal in length,

1 stouter than 2. Prothorax slightly broader than long, rounded at the sides, somewhat coarsely,

closely punctate. Elytra about one-half wider than the prothorax, subparallel to near the middle, rather

coarsely punctate-striate, the interstices convex, shining, and about as wide as the stris, and each with

a row of sete.

CERATOPUS. 123

Group CERATOPINA.

Cératopides, Lacordaire.

This group seems to me to be nearly allied to the Erirrhina, from which it is widely

separated by Lacordaire.

CERATOPUS.

Ceratopus, Schénherr, Gen. Cure. vii. 2, p. 120 (1843) ; Lacordaire, Gen. Col. vi. p. 591.

Acanthobrachium, Boheman, Freg. Eug. Resa, Ins. p. 128 (1859) ; Lacordaire, loc. cit. p. 592.

The various new forms now described show that Ceratopus and Acanthobrachium

cannot be maintained as distinct, the only difference (following Lacordaire) being the

ereater extension of the scrobes posteriorly in the latter. They are easily recognizable

by the very large triangular tooth on each of the femora and the appendiculate tarsal

claws. The genus is peculiar to Tropical America, ranging from the Mexican State of

Vera Cruz to Brazil. The seven species here enumerated may be grouped thus :—

a. Scrobes becoming shallow or evanescent beneath the rostrum posteriorly, thus

appearing confluent behind; tibial claw short or absent. [CrRartorus sensu

Elongate-ovate, shining, piceous, the basal half of the antenne rufescent ; somewhat thickly clothed with small,

oblong, intermixed, cinereous and brown scales, the darker scales forming two incomplete fascize and

various spots or streaks on the elytra, the latter with a small pale ochreous spot (surrounded by brown

scales) on the fifth interstice towards the apex ; the squamosity of the under surface cinereous. Head

closely, minutely punctate; rostrum elongate, twice the length of the prothorax, finely punctured at the

sides towards the base, and there carinate, for the rest smooth and shining; antenne inserted slightly

before the middle of the rostrum, joint 1 of the funiculus about twice as long as 2, the club nearly as

long as joints 4—7 united. Prothorax transverse, narrowed and slightly constricted in front, the sides

Oblong, rather broad, shining, piceous, the basal half of the antennz, the femora, and tibize rufescent; some-

what thickly clothed with small, narrow, intermixed, flavo-cinereous and brown scales, which give a

mottled appearance to the elytra, the latter with a conspicuous pallid spot on the fifth interstice towards

the apex. Head finely punctate; rostrum about as long as the head and prothorax, closely punctate and

finely carinate in its basal two-thirds, smoother thence to the apex; antenne rather stout, inserted at

about one-third from the apex of the rostrum, joint 1 of the funiculus one-half longer than 2, the club

Length 43-53, breadth 22-24 millim.

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

Three specimens, probably all females, two of which show the tessellate arrangement

of the differently-coloured scales on the alternate elytral interstices. Less convex than

C. longiclava, the prothorax more transverse, the antennal club of normal length, the

elytra feebly emarginate at the sutural angle and with the markings very different,

the legs not so stout, the rostrum more slender.

p. 990.

In this genus, the type of which was from the Amazons, tlie tarsal claws have a long

tooth (as in the typical Anthonomi), the anterior femora and tibie are formed as in

Prionomerus, and the head, rostrum, and prothorax much as in Ceratopus, with which

Lacordaire associates it, mainly on account of the sinuous anterior margin of the

prothorax, the latter having feeble ocular lobes. A single species of Chelotonyx from

Mexico is contained in our collection.

1. Chelotonyx fasciculatus, sp.n. (Tab. IX. figg. 1, 1a.)

Oblong-ovate, coarse, shining, nigro-piceous, with a faint brassy lustre, the antenne and tarsi obscure ferru-

ginous ; somewhat sparsely clothed with long, decumbent, ochreous pubescence, which is here and there

clustered into fascicles on the elytra, the vestiture of the under surface whitish and scattered. Head

sparsely punctured, foveate between the eyes, which are transverse, depressed, and rather narrowly

separated ; rostrum stout, curved, about as long as the head and prothorax, narrowing a little at the apex,

closely, irregularly seriate-punctate, the antenne inserted at one-third from the tip. Prothorax trans-

verse, rounded at the sides, much narrowed and constricted in front, closely, irregularly punctate. Elytra

moderately long, a little wider than the prothorax, subparallel at the base, the humeri obtuse; very

deeply punctate-striate, the interstices strongly convex and rugulosely punctate. Legs stout; anterior

coxee somewhat widely separated ; anterior femora strongly clavate, the very large triangular tooth finely

serrate externally ; anterior and intermediate tibie with a strong claw, the anterior pair simply curved,

not sinuate within, ciliate on their inner edge.

Length 4, breadth 2 millim.

Hab. Mexico, 'Teapa in Tabasco (H. H. Smith).

Two specimens, their sex not ascertained. Much smaller than C. bates’, Wat., the

prothorax rounded at the sides, the elytra narrower, with the interstices convex, the

anterior tibiz not sinuate within, the femoral tooth more finely serrate, the rostrum

not widened at the apex. |

GRYPIDIOPSIS. 127

Group ERIRRHINA.

As at present recognized, this group includes a great variety of forms, some with a

long claw at the apex of the tibia, and others with the tibie unarmed, but all

having simple tarsal claws, these being connate in the Smicronychina. In the

Anthonomina the tarsal claws in nearly all the species are toothed or appendiculate.

Sect. ERIRRHINIDES.

GRYPIDIOPSIS, gen. nov.

Rostrum stout, widening outwards, a little longer than the prothorax, almost straight, the scrobes lateral,

descending to the lower anterior margin of the eyes, the anterior opening visible from above; antenne

inserted near the apex of the rostrum, the scape long, the funiculus 7-jointed, joint 2 nearly as long as 1,

the club ovate and pubescent; mandibles bifid; eyes large, lateral transverse, finely facetted; head

convex ; prothorax transverse, convex, much narrower than the elytra, with broad ocular lobes; scutellum

very small; prosternum rather short, emarginate in front, level in front of the anterior coxe, which are

contiguous ; ventral segments 3 and 4 much shorter than 2 or 5, the sutures straight, 2-4 slightly

produced at the outer apical angle ; femora clavate and armed towards the apex with a short acute tooth ;

tibie: sinnous within, obliquely truncate at the apex, mucronate, and armed with a long claw at the inner

apical angle ; tarsi villose, spongy-pubescent beneath, the third joint strongly bilobed, the claws simple

and divergent ; body shaped much as in Procas and Girypidius ; vestiture consisting of short, fine, narrow

scales.

The single species referred to this genus has quite the facies of a Procas or

Grypidius, from which it differs in the toothed femora, the comparatively short

rostrum, &c. It is almost intermediate between the Hylobiids and the true

Erirrhinids.

1. Grypidiopsis variegatus, sp. n. (Tab. VIII. figg. 10, 10a, 3.)

Subovate, rather broad, slightly shining, black, the antennew (the club excepted), the outer half of the tibia,

and the tarsi obscure ferruginous; somewhat thickly clothed with narrow brownish-ochreous scales, the

prothorax and elytra with small patches of cinereous scales intermixed. Head densely punctate, deeply

foveate between the eyes ; rostrum rugosely punctured, longitudinally wrinkled, finely carinate down

the middle ; eyes separated above by a little less than the width of the base of the rostrum ; joint 2 of the

funiculus slightly longer than 3 and 4 united, the outer joints transverse and scarcely wider. Prothorax

convex, transverse, much narrowed and slightly constricted in front, parallel behind, densely, finely

punctate, with a narrow, smooth, shining space down the middle. Elytra somewhat triangular in shape,

a little flattened on the disc, at the base more than one-half wider than the prothorax, with the apices

conjointly produced and the obtuse humeri very prominent; coarsely punctate-striate, the interstices

convex, rugulosely punctate, and here and there transversely connected. Beneath closely punctate, the

first ventral segments broadly and shallowly depressed down the middle,

One specimen, without definite locality, apparently female, not in sufficiently perfect

condition for description. This insect is of the same size as D. brevisetosus, but is

without the short sete on the elytra; it is obscure ferruginous in colour, with the disc

of the prothorax and some irregular longitudinal streaks on the elytra black.

GRASIDIUS, gen. nov.

Kostrum slender, curved, a little widened at the base and apex, longer than the head and prothorax united ;

scrobes lateral, descending to the lower anterior margin of the eyes; antenne inserted a little before the

middle of the rostrum, slender, the funiculus 7-jointed, the club ovate, annulate, and pubescent ; eyes

large, not prominent, transverse-oval ; head sunk into the prothorax up to the eyes; prothorax convex,

without ocular lobes; scutellum minute ; elytra oblong-ovate, a little wider than the prothorax, finely

punctate-striate, covering the pygidium; prosternum moderately developed in front of the anterior coxe,

level, unemarginate in front; anterior coxe contiguous; ventral segments 3 and 4 shorter than 2 or 5,

the sutures straight ; legs slender and moderately long, the anterior pair much longer than the others ;

femora slightly incrassate, unarmed ; tibiw straight, truncate and unarmed at the apex ; tarsi pubescent

beneath, joint 3 dilated and bilobed, 4 as long as the others united, the claws well developed, divergent,

and simple; body elongate; vestiture consisting of appressed pubescence and semierect seta.

The small species from which the above characters are taken has much the facies of

the European genus Thryogenes, Bedel (type 7. festucw, Herbst), differing from it in

the straight unarmed tibie, the transverse eyes, the setigerous vestiture (recalling that

of Orthochetes and Pseudostyphius), &c. It can be included in the Erirrhinides for

the present.

* Capt. Casey states (op. cit. p. 361) that the genus is probably represented throughout the elevated central

region of Mexico, but this does not prove to be the case.

GRASIDIUS.—SMICRONYX. 129

1. Grasidius longimanus, sp. n. (Tab. VIII. figg. 11, lla, 2.)

Elongate-ovate, shining, ferruginous, thickly clothed with pallid appressed pubescence, the upper surface also

with a coarse, semierect setosity. Rostrum about one-third longer than the prothorax, rugulose and

pubescent at the base, smooth and glabrous beyond; joint 1 of the funiculus obovate, rather stout,

2 shorter and more slender, 3-7 short and increasing very little in width. Prothorax convex, nearly as

long as broad, rounded at the sides anteriorly, much narrowed in front, subparallel behind, the surface

A holarctic genus, divided into four by Dietz (Joc. cit.), and very numerously repre-

sented in North America *. Seven species are known to me from within our limits

(and five of these by single examples), six belonging to Smicronyx or Synertha and one

to Desmoris, the genus ranging as far south as Guatemala. These insects are easily

recognizable by their subconnate, simple tarsal claws, the transverse groove at the base

of the rostrum above, and the almost straight ventral sutures, the surface clothed with

coarse, oval or piliform scales. Several of the European species are attached to Cuscuta,

a genus of climbing, leafless, parasitic plants (numerous in Mexico), and it is not

unlikely that this is the food of the American forms also.

1. Smicronyx tectus, sp. n.

Oblong-ovate, black, the tip of the rostrum, the antenne, and legs (the base of the femora excepted) more or

less ferruginous ; the entire surface densely clothed with coarse, oval, overlapping scales, which are of a.

pale brownish colour variegated with whitish, and also with scattered, decumbent, white sete, these

becoming coarser on the elytra and arranged in a single series on each interstice. Rostrum strongly

Hab. Mzxico, Amula in Guerrero (H. H. Smith).

One specimen. Very similar to a Texan insect sent to me by Mr. Wickham under

the name of S. spurcus, Casey, but narrower and more convex, with coarser, whiter,

more oblong scales, and a much stouter rostrum. The eyes appear to be contiguous

beneath.

3. Smicronyx cataphractus, sp.n. (Tab. VIII. fig. 12.)

Oblong-ovate, black, densely clothed with intermixed, white and brown, coarse, oval, imbricate scales, the

white scales forming a median vitta on the prothorax and numerous spots and short streaks on the elytra,

and with scattered, fine, curled, decumbent seta. Rostrum about as long as the head and prothorax,

constricted at the base, stout, tapering outwards, rugulose, smooth and shining at the tip, the antenne

inserted slightly before the middle, the eyes contiguous beneath. Prothorax broader than long, convex,

rounded at the sides, a little more narrowed in front than at the base, finely punctate. Elytra about

4. Smicronyx thoracatus, sp. n.

Oblong-ovate, black, the outer half or more of the elytra, and the femora and tibie, usually rufescent ;

the surface thickly clothed with uniformly coloured, pale greyish, oval, moderately coarse, imbricate

scales, the elytral interstices each with a row of curled, decumbent sete. Rostrum moderately stout,

feebly constricted at the base, about as long as the prothorax, rugulose to near the tip, the antenne

inserted a little before the middle; eyes contiguous beneath. Prothorax convex, about as long as broad,

rounded at the sides, narrowed and constricted in front, and slightly narrowed behind ; the surface

closely, somewhat coarsely punctate, the disc with a smooth median line. Elytra one-half wider than

tured, the interstices flat and punctulate.

Length 23-24 millim. (¢.)

Hab. Mexico, Guanajuato (Sallé).

Five specimens. Distinguishable from our other species, S. constrictus excepted, by

the uniformly coloured, pale greyish, oval scales, the elytra with conspicuous decumbent

sete. The tarsal claws are shorter than in S. constrictus, and the squamosity is

imbricate. WS. thoracatus belongs to the section Synertha, Dietz, and seems to be nearly

allied to S. imbricatus, Casey. |

Oblong-ovate, shining, black, the femora and tibie partly rufescent ; the surface thickly clothed with coarse,

pale brownish, oval, imbricate scales, with a few white ones intermixed, the elytral interstices each with

a row of curled, decumbent setz. Rostrum slender, feebly constricted at the base, curved, nearly one-

half longer than the prothorax, smooth and shining, punctulate at the sides towards the base; antennz

long and slender, inserted at the middle of the rostrum; eyes contiguous beneath. Prothorax convex,

nearly as long as broad, moderately rounded at the sides, rather sparsely punctate, the disc with a smooth

median line. Elytra more than one-half broader than the prothorax, subparallel towards the base,

with fine, sharply-cut strie, the outer strie distinctly punctured, the interstices almost flat and faintly

punctulate. Legs comparatively slender.

Length 1%, millim. (2.)

Hab. Mextco, Guanajuato (Sallé).

One specimen. Smaller and less elongate than S. thoracatus, with a long, smooth,

slender rostrum, slender antenne, a smaller and less closely punctured prothorax, and

more slender legs, the vestiture of the elytra mottled. From the same sex of S. spurcus

the present species may be distinguished by the somewhat sparsely punctured prothorax

and the more shining surface.

6. Smicronyx tenuisquamis, sp. n.

Oblong-ovate, rather dull, black, the sides of the elytra very broadly, and the femora and tibie, rufescent ;

the surface sparsely clothed with coarse, decumbent, white, piliform scales. Rostrum stout, cylindrical,

OCHETINA.

Ochetina, Pascoe, Ann. & Mag. Nat. Hist. (5) vii. p. 8302 (1881).

A single species from the Amazons was referred to this genus by Pascoe, and a

second from Guatemala is now added. Ochetina is very closely related to Onychylis,

Lec., differing from it in the narrow third tarsal joint, the elongate rostrum and

antenne, the long tarsal claws, &c. ‘The funiculus is 6-jointed, the first and second

joints elongate. The prosternum is level. The tibie (as in Onychylis) are grooved

along their upper and lower edges, the inner surface being densely pubescent.

equal in length, 1 stouter than 2; eyes large, transverse, coarsely facetted, narrowly separated beneath.

Prothorax convex, transverse, rounded at the sides, strongly bisinuate at the base, not constricted in

front ; the surface (when cleaned) alutaceous and finely punctate. Elytra much wider than the pro-

thorax, deeply striate, the strie with scattered punctures, the interstices convex and alutaceous, the

humeri broadly rounded. Legs stout; tarsi elongate, the third joint slightly wider than the second and

feebly excavate at the apex.

Length 4, breadth 2 millim. (? 3.)

Hab. GuaTEMALA, Paso Antonio (Champion).

One specimen, from a lagoon in the savana-region of the Pacific slope. Very like

O. uniformis, Pasc., from the Amazons, but narrower and a little more convex, the

rostrum shorter and with the antenne inserted much nearer the tip, the prothorax

strongly sinuate at the base and with the surface much smoother, the elytra without

distinct rounded prominences, the humeri rounded (instead of subangular). ‘The type

of O. uniformis is a female, that of O. induta probably a male.

ONYCHYILIS.

‘Onychylis, Leconte, Proc. Am. Phil. Soc. xv. p. 178 (1876).

This genus includes a few American species closely related to Bagous. They have

the tibie stout, sinuous, shallowly grooved on the inner side, and truncated at the

apex; the third tarsal joint dilated and bilobed; the funiculus 6-jointed; and the

prosternum level. ‘The rostrum, too, is almost smooth, shining, and glabrous in

the females, and squamose and rugulose to near the tip in the males. The Central-

American forms, like those belonging to the genus Lissorhoptrus, are extremely closely

allied to those inhabiting the United States.

1. Onychylis meridionalis, sp. n. (Tab. VIII. figg. 14, 144, ¢.)

Obovate, dull black, densely clothed with rather shining, greyish, agglutinated scales, the prothorax with two

paler vittze on the disc and the elytra with lighter and darker markings, appearing to have a common

V-shaped darker fascia on the disc and an oblong mark on the suture in front of this, the antenne and

the legs in part ferruginous. Rostrum moderately stout, curved, rather longer than the prothorax,—

in the ¢ densely rugulose, squamose, and dull to near the tip, in the Q shining, sparsely punctate, and

glabrous. Prothorax strongly transverse, rounded at the sides, slightly constricted in front, bisinuate at

the base, the surface closely and somewhat coarsely punctate. LElytra fully one-half wider than the

prothorax, rather short, deeply striate, the stria with moderately coarse, somewhat distantly placed

punctures, the interstices convex and densely reticulate, the pale spots towards the sides and apex

apparently arising from feeble elevations. Legs moderately stout; third tarsal joint broad, bilobed.

2. Onychylis setiger, sp. n.

Oblong-ovate, dull, black, densely clothed with brownish-grey, rather shining, agglutinated scales, the pro-

thorax with two paler vite: on the disc, and the elytra mottled with whitish towards the sides and

sometimes with an interrupted fascia towards the apex, the rostrum, antenna, and legs obscure

ferruginous. Rostrum strongly curved, moderately stout, a little longer than the prothorax, bare,

shining, sparsely punctate. Prothorax transverse, rounded at the sides, constricted in front, densely,

rather coarsely punctate. Elytra moderately long, much wider than the prothorax, a little flattened on

the disc and subparallel towards the base, deeply striate, the punctures of the striae indistinct, the inter-

stices almost flat and densely reticulate, the alternate ones each with a scattered series of short, fine,

decumbent, pallid setee. Legs moderately stout; tibie finely denticulate and ciliate within; third tarsal

joint broad, bilobed.

Length 3-34, breadth 1} millim. (@.)

Hab. Mexico, Amula in Guerrero (H. H. Smith).

Four specimens. ‘This species, to judge from the description, must be nearly allied

to O. alternans, Lec., from Texas, which also has the alternate elytral interstices

setigerous; but differs from it in having the prothorax constricted in front and the

tarsi broader, the third joint of the latter being strongly bilobed.

3. Onychylis cretatus, sp. n.

Subovate, rather broad, black, the tip of the rostrum, the antenne, and tarsi ferruginous ; the entire surface,

the tip of the rostrum excepted, thickly coated with opaque, greyish-white, agglutinated scales, the

rostrum, prothorax, and legs clothed with short, fine, curled hairs, the elytra with a series of fine, curled

sete on each of the alternate interstices. Rostrum stout, curved, slightly longer than the prothorax,

smooth and shining at the tip. Prothorax transverse, rounded at the sides, a little more narrowed in

front than at the base, with rather prominent ocular lobes ; the surface (beneath the squamosity) dull,

alutaceous, and excessively minutely punctate. Elytra subcordate, at the base one-half wider than the

prothorax, the apices a little produced and conjointly rounded; the surface (beneath the squamosity)

shining, deeply punctate-striate, the interstices narrow, convex, and rugulose, the alternate ones more

LISSORHOPTRUS.

Lissorhoptrus, Leconte, Proc. Am. Phil. Soc. xv. p. 183 (1876).

The species referred to this genus have the rostrum very stout and comparatively

short; the antennal club smooth and shining for two-thirds of its length (as in the

European Llmidomorphus); the funiculus 6-jointed; the tibia stout, mucronate,

and armed with a long hook at the inner apical angle, the intermediate pair strongly

PYR/ECHMES, gen. nov.

Rostrum stout, curved, widened at the apex, as long as the prothorax, slightly constricted at the base, the

scrobes descending at once, their anterior opening visible from above ; antenne inserted near the apex of

the rostrum, rather long, the funiculus 7-jointed—joint 1 stout, 2-7 very gradually widening,—the club

ovate, shining, and sparsely pubescent; eyes transverse, finely facetted ; prothorax convex, nearly as

long as broad; scutellum not visible ; elytra oblong, much wider than the prothorax, with very prominent,

obliquely truncated humeri; prosternum emarginate at the apex, short, flattened in front ; anterior coxe

contiguous, the intermediate pair narrowly, the hind pair very widely, separated; ventral segments 1

and 2 very short, the sutures straight ; femora moderately incrassate, unarmed ; tibize curved, stout,

ovate, covered with a dense clothing of agglutinated scales.

The single species from which the above characters are taken is related to Onychylis,

Bagous, and other allied genera, but cannot be included in any of them. The chief

characters are the short, stout, smooth tarsi, with bilobed third joint and feebly

developed claws, the apically inserted, rather long antenne, with sparsely pubescent

club, the long tibial claws, and the rapidly descending scrobes.

1. Pyrechmes brevitarsis, sp.n. (Tab. VIII. figg. 17, 17 a.)

Oblong-ovate, nigro-piceous, the tip of the rostrum, the antenne, tibie, and tarsi ferruginous ; the surface

densely clothed with brownish-grey agglutinated scales, the prothorax with a large patch on the disc

behind, and the elytra with a common transverse patch at the base and a rather broad transverse fascia

a little beyond the middle, dark brown, and also with scattered, fine, curled, decumbent sete, which are

serially arranged on the elytra. Rostrum bare and shining at the tip; joint 2 of the funiculus a little

This genus, to which six North-American species are referred by Leconte, will

probably have either to be sunk as synonymous with Tanysphyrus, or restricted to

those forms with a large terminal joint (6th) to the funiculus, a character possessed by

the type, E. limatulus (Gyll.). In most or all of the other forms the joints 2-6 of

the funiculus are sma]l and narrow, as in Tanysphyrus. The tarsi are very stout, the

third joint dilated and strongly bilobed, the fourth scarcely extending beyond it.

E. eratus. They are oblong in shape, and of a dull golden or coppery colour,

with a greyish or whitish squamosity (which is easily rubbed off) at the sides of

the prothorax, at the base of the elytra near the shoulders, and over the whole of

the under surface. The prothorax is transverse, rounded at the sides, and densely

UDEUS, gen. nov.

ostrum rather slender, parallel-sided, about as long as the prothorax, the scrobes descending to the lower

anterior margin of the eyes; antenne inserted at the middle of the rostrum, the scape reaching to beyond

the middle of the eyes, the funiculus 6-jointed—joint 1 rather stout, 2-6 slender, very slightly increasing

in width, all longer than broad,—the club ovate, acuminate; eyes lateral, rounded, large, prominent,

coarsely facetted ; head convex, sunk into the prothorax to near the eyes; prothorax narrow, transverse,

convex, truncate at the base and apex; scutellum very small, triangular; elytra oblong, truncated at the

base, much wider than the prothorax, coverimg the pygidium ; anterior coxe globose, separated by a very

thin lamina; anterior portion of the prosternum rather broad, truncate in front; ventral segments 1 and

2 connate at the middle, 3 and 4 shorter than 2 or 5, the sutures straight; femora clavate and each

armed with an acute triangular tooth; tibie narrow, obliquely truncate at the tip; tarsi slender,

sparsely villose beneath, the third joint bilobed, the fourth very slender and as long as 1 and 2 united,

the claws simple, divergent ; body oblong-ovate, pubescent.

This genus includes a single species from Mexico and Guatemala. It is nearest

allied to HKugnomus, a New Zealand form, but has a slender 6-jointed funiculus to the

antennz, the antenne themselves being inserted at about the middle of the rostrum,

and the head is more deeply sunk into the prothorax. ‘The vestiture consists entirely

of fine pubescence. ‘The insect has much the facies of a small pallid Rhynchites.

Sect. DERELOMIDES.

The Derelomides are widely separated from the Erirrhina by both Lacordaire and

Leconte, notwithstanding the close affinity of Derelomus and Phyllotrox, the latter

being referred by them to the Eugnomides.

DERELOMUS.

Derelomus, Schéuherr, Curc. Disp. Meth. p. 235 (1826) ; Gen. Cure. ii. p. 629; Lacordaire, Gen.

Col. vii. p. 10.

Notolomus, Leconte, Proc. Am. Phil. Soc. xv. p. 222 (1876).

This widely distributed genus includes a few species, most of which are apparently

found on palms, two of the North-American forms and one of the European, at least,

attacking Chamerops. Notolomus is connected with Derelomus by intermediate

forms *, the extent of separation of the anterior cox varying according to the species.

1. Derelomus estriatus, sp. n.

Oblong-ovate, rather broad, opaque, the elytra somewhat shining, thickly clothed with very fine short pubescence,

luteous, the eyes black, the entire surface closely, minutely punctate. Rostrum eurved, rather stout, about

as long as the prothorax; antenne inserted at a little before the middle of the rostrum, joints 2-7 of

the funiculus short, increasing in width, 7 as wide as the club. Prothorax transverse, nearly as wide

as the elytra, constricted in front, immarginate laterally, the sides gradually and arcuately converging

from a little before the base to the apex, the base feebly bisinuate. Elytra almost without trace of

strie, Anterior cox moderately separated, the intercoxal portion of the prosternum parallel-sided, but

widening posteriorly.

Length 23, breadth 14 millim.

Hab. Mexico, Jalapa (f/ége).

One specimen.

9. Derelomus palmarum, sp.n. (Tab. VIII. fig. 24, 24a, 0.)

Oblong-ovate, opaque, the elytra somewhat shining, very finely and closely pubescent, luteous, the eyes black,

the entire surface closely, minutely punctate. Rostrum moderately curved, about as long as the prothorax ;

antenne: inserted at (@) or before (¢) the middle of the rostrum, joints 2-7 of the funiculus short,

gradually increasing in width. Prothorax transverse, nearly as wide as the elytra, immarginate laterally,

constricted in front, bisinuate at the base, the sides gradually and arcuately converging from a little before

the base tothe apex. Elytra obsoletely striate towards the base. Anterior cox separated by a triangular

process of the prosternum, which is reduced to a thin lamella posteriorly.

Length 2}-23, breadth 1 millim. (¢ Q.)

Hab. Mexico, Manantial (Flohr); Panama, Volcan de Chiriqui (Champion).

Found in plenty on the flowers of a small palm in Chiriqui; a single specimen only

seen from Mexico. Very like D. estriatus, but a little narrower, the elytra faintly striate

towards the base, the anterior coxee more approximate.

* Leconte also states that the tarsal claws are broadly toothed, but in a specimen of his V. bicolor before

me I fail to see the tooth.

DERELOMINUS.—PHYLLOTROX. 141

DERELOMINUS, gen. nov.

Anterior coxe contiguous; antennz long and slender, the funiculus 6-jointed, 1 and 2 elongate, the club with

distinct sutures ; rostrum very elongate; the other characters as in Derelomus.

This genus includes a single species from British Honduras.

1. Derelominus piceus, sp. n.

Oblong-ovate, rather broad, opaque, the elytra somewhat shining, very finely and closely pubescent, piceous,

the legs and antenne paler, the entire surface densely, minutely, rugulosely punctate. Rostrum rather

slender, strongly curved, very elongate, much longer than the prothorax, smoother and shining at the

tip; antenne inserted at the middle of the rostrum, slender, joint 1 of the funiculus elongate, 2-6

gradually increasing in width, 2 twice as long as 3, 3-6 about as long as broad ; eyes not very prominent,

finely facetted. Prothorax transverse, much rounded at the sides before the middle, immarginate laterally,

feebly constricted in front, bisinuate at the base, nearly as wide as the elytra. Elytra shallowly

striate. First ventral segment sulcate down the middle.

PHYLLOTROX.

Phyllotrox, Schénherr, Gen. Cure. vii. 2, p. 189 (1843); Lacordaire, Gen. Col. vi. p. 505 ; Leconte,

Proc. Am Phil. Soc. xv. p. 174; Kirsch, Berl. ent. Zeitschr. 1874, p. 4.05.

Euclyptus, Dietz, Trans. Am. Ent. Soe. xviii. p. 271 (1891).

This genus includes numerous minute American forms, about twenty of which have

been described. It is chiefly distinguishable amongst its allies by the very short

funiculus of the antenne, joints 3-7* of which are transverse and become progressively

wider, 5 and 6 appearing at first sight to form part of the club, joint 1 being stout and

rather large, the contiguous anterior coxe, and the simple tarsal claws. ‘The inter-

mediate tibie are conspicuously dilated at the outer apical angle in some of the species.

The ventral segments 1 and 2 are more or less connate, and 3 and 4 very short. ‘The

pygidium, which is sometimes visible, is deeply foveate or sulcate in many of the

specimens examined, and this is perhaps a sexual or specific peculiarity. ‘The species

are extremely difficult to distinguish in some cases, and I am not at all certain about

the limits of several of them. The Central-American forms may be grouped thus :—

a. Eyes very large, contiguous . . «©. 6 6 ee ee ee ew ee ee «Species 1.

b. Eyes smaller, somewhat widely separated.

142 RHYNCHOPHORA.

1. Phyllotrox megalops, sp. n. (Tab. VIII. fig. 25, 2 .)

Elongate-ovate, narrow, subopaque, obscure testaceous, the eyes black; finely pubescent, the pubescence

golden in colour and seriately arranged on the elytra. Rostrum slender, distinctly longer than the

prothorax, curved, minutely punctured; eyes coarsely facetted, large, contiguous above and beneath.

Prothorax transverse, rounded at the sides, equally narrowed in front and behind, closely, very minutely

punctate. Elytra oblong-oval, obsoletely seriate-punctate, the pubescence on each of the interstices

arising from a faintly raised line. Tibia straight on their outer edge.

Length 13 millim. (2.)

Hab. GuateMaua, Panzos in Vera Paz (Champion).

One specimen. Easily recognizable by its narrow, elongate shape, the large,

coarsely facetted, contiguous eyes, and the slender rostrum.

P. speculator, Kirsch, from Peru, is perhaps an allied form.

2. Phyllotrox ater, sp.n. (Tab. VIII. figg. 26, 26 a.)

Ovate, moderately shining, black, the legs sometimes piceous, the scape of the antenne, the tip of the rostrum,

and the terminal tarsal joint rufo-testaceous; clothed with a very fine, sparse pubescence. Rostrum

curved, rather stuut, about as long as the prothorax, faintly sulcate down the middle, densely, rugulosely

punctate, smoother at the tip; eyes large. Prothorax convex, nearly as long as broad, rounded at the

sides, considerably narrowed and constricted in front and also a little narrowed behind, and transversely

grooved immediately before the basal margin; the surface densely punctate, sometimes with indications

of a faintly raised median line. Elytra ovate, punctate-striate, the interstices more or less convex and

very faintly punctate. Legs comparatively elongate, with the femora stout and the intermediate tibiv

slightly dilated at the outer apical angle.

Length 23-3 millim.

Hab. GuateMALa, Chiacam and Sinanja in Vera Paz (Champion).

Four specimens. Distinguishable by its black cclour, ovate, convex form, and

sparse pubescence. P. subopacus, Schauf., from Colombia, is similarly coloured, but

differs in various details. The transverse groove at the base of the prothorax is

conspicuous. In three of the examples the pygidium is visible and foveate.

8. Phyllotrox mecinoides, sp. n. (Tab. VIII. figg. 27, 27 a, ¢.)

Oblong-ovate, shining; black, each elytron usually with an anteriorly narrowing evanescent patch on the dise

extending from the apex towards the shoulder, and sometimes reaching it, rufo-testaceous, and the tibis

in most specimens similarly coloured ; the surface griseo-pubescent, the pubescence serially arranged on

the elytra. Rostrum a little shorter than the prothorax, rather stout, moderately curved, rugulosely

punctate, faintly grooved above. Prothorax broader than long, abruptly narrowed in front and slightly

narrowed at the base, the sides almost straight; the surface closely punctate, sometimes with a narrow

smooth space down the centre. LElytra oblong, punctate-striate, the interstices flat and rugulosely

punctate. Legs comparatively stout, the intermediate tibie acutely dilated at the outer apical angle.

Pygidium foveate, and the fifth segment emarginate at the apex, in the ¢.

Length 24-3 millim. (¢ 2.)

Hab. Mexico, Jacale * (Sal/é).

Six specimens. Very like a Mecinus, a genus not known in America, but agreeing

with Phyllotrox in the structure of the antennee &c. .

* Probably ‘Jacala” in Hidalgo.

PHYLLOTROX. 143

4. Phyllotrox montanus, sp. n.

Oblong-ovate, shining; black, the scape and funiculus of the antenne and the apex of the abdomen rufo-

testaceous, the elytra similarly coloured, but with a large subtriangular patch at the base, extending

along the suture to beyond the middle, and the sides narrowly for the same distance, piceous or black,

the legs ruto-testaceous, with the femora more or less piceous; the surface finely and somewhat thickly

pubescent, the pubescence serially arranged on the elytra. Rostrum stout, feebly curved, a little shorter

than the prothorax, rugulosely punctured. Prothorax transverse, slightly rounded at the sides, narrowed

in front and behind, closely punctate, with a smooth, abbreviated, median line towards the base. LElytra

oblong, a little wider than the prothorax, subparallel in their basal half, punctate-striate, the interstices

flattened and rugulosely punctate. Legs short and stout, the intermediate tibiee acutely dilated at the

outer apical angle. Pygidium deeply sulcate in the ¢.

Length 23-23 millim. (d 2.)

Hab. Guatema.a, Volcan de Agua, between 8500-10,500 feet (Champion).

One pair. Closely allied to P. mecinoides, but smaller and less elongate,

the prothorax relatively broader, the antenne in great part and the tarsi rufo-

testaceous. |

5. Phylotrox crassipes, sp.n. (Tab. VIII. fig. 28, ¢.)

Oblong-ovate, shining; nigro- or rufo-piceous, the antenne (the club excepted), legs, ventral surface, and

elytra testaceous, the suture of the latter faintly infuscate at the base; clothed with fine golden

pubescence, which is serially arranged on the elytra, Rostrum rather stout, feebly curved, rugulosely

punctate, shorter than the prothorax. Prothorax transverse, rounded at the sides, a little more narrowed

in front than behind, closely punctate. Elytra oblong-oval, punctate-striate, the interstices convex

throughout and minutely punctate. Legs stout, the intermediate tibie dilated at the outer apical angle.

Pygidium deeply sulcate.

Length 24-23 millim. (¢.)

Hab. Mexico, Villa Alta in Oaxaca (Mohr).

Two specimens. Distinguishable from P. suturalis and the other closely allied

forms by the stout legs and the rounded sides of the prothorax. ‘The prothorax and

elytra are more rounded at the sides than in P. montanus, the interstices of the latter

strongly convex.

6. Phyllotrox suturalis. (Tab. VIII. fig. 29.)

Derelomus suturalis, Boh. in Schénh. Gen. Cure. viii. 1, p. 96°.

Oblong-ovate, somewhat shining, clothed with fine pallid or golden pubescence; black or piceous, the antennz

(the club excepted), the tip of the rostrum, the legs, and the abdomen in great part, ferruginous or

testaceous ; the elytra testaceous, with a triangular scutellar patch extending down the suture, or the

suture only, black. Rostrum about as long as the prothorax in the ¢, longer in the Q; rugulosely

punctate. Prothorax broader than long, considerably narrowed in front and slightly so behind, densely

punctate. Elytra oblong-ovate, punctate-striate, the interstices more or less convex and rugulosely

punctulate. Intermediate tibie dilated at the outer apical angle.

144 RHYNCHOPHORA.

Hab. Mexico! (Mus. Brit., Truqui), Zacualtipan, Cordova (Hé9e), Guanajuato,

Toxpam, Orizaba (Sallé), Amatan (Flohr), Omilteme, Xucumanatlan, Chilpancingo,

Teapa (H. H. Smith); Guaremaua, Quezaltenango, Volcan de Agua, Calderas,

Capetillo, Duefias (Champion), Coban (Conradt).

A large number of specimens from Mexico and Guatemala are provisionally referred

to this species, the type of which I have seen. The colour is very variable, and the

‘rostrum also varies in length. The pygidium is broadly and deeply sulcate in most

of the individuals in which it is exposed, and this may be a peculiarity of the males.

The numerous examples from Quezaltenango are very small, dark, and narrow, and

others from Zacualtipan are entirely ferruginous, with the rostrum longer and more

curved than usual. P. suturalis is extremely like the North-American P. nudifer,

‘Lec.*, but it differs in being a little narrower and less robust. P. variabilis, Schauf.,

a larger insect from Colombia, is described as being equally variable in colour.

7. Phyllotrox fulvus, sp. n.

Oblong-ovate, shining, finely pubescent, ferruginous, the elytra and legs testaceous. Rostrum nearly as long

as the prothorax, closely punctate. Prothorax a little broader than long, rounded at the sides, much

narrowed in front and slightly so behind, closely, finely punctate. LElytra ovate, finely and shallowly

punctate-striate, the interstices flat and each with about two irregular rows of very minute punctures.

Pygidium visible and with a deep oblong fovea in the middle. Ventral segments finely punctured,

the first impressed in the middle. Legs rather elongate, the tibi not dilated at the outer apical

angle.

Length 2,%, millim. (¢.)

Hab. Panama, Volcan de Chiriqui (Champion).

One specimen. A rather large form, with finely punctate-striate elytra, the

interstices flat and minutely, irregularly biseriate-punctate.

8. Phyllotrox marcidus, sp. n.

Ovate, subopaque, thickly clothed with fine golden pubescence ; ferruginous, the antenne (the club excepted),

elytra, and legs testaceous. Rostrum about as long as the prothorax, rugulosely punctate. Prothorax

convex, transverse, comparatively broad, rounded at the sides, narrowed in front and slightly so behind,

densely punctate. Elytra oval, comparatively short, punctate-striate, the interstices narrow, convex, and

rugulose. Legs short.

Length 12 millim.

Hab. Paxama, Volcan de Chiriqui (Champion).

One specimen. Recognizable by its small size, short form, comparatively broad

prothorax, and dull surface. The prothorax is relatively broader than in individuals

of P. suturalis of the same size.

* We are indebted to Mr. H. F. Wickham for specimens of this species from Leadville, Colorado.

PHYLLOTROX. 145

9. Phyllotrox inconspicuus, sp. n.

Ovate, shining, finely pubescent, testaceous. Rostrum about as long as the prothorax, rugulosely punctate.

Prothorax convex, transverse, comparatively broad, rounded at the sides, narrowed in front and slightly

so behind, closely, finely punctate. Elytra oval, short, punctate-striate, the interstices flat and each

with a series of minute punctures. Legs short.

Length 14 millim.

Hab. Nicaracva, Chontales (Janson).

One abraded example, very closely allied to P. marcidus, but differing too much to

be included under that species. Broader and more robust than the small varieties

of P. suturalis.

10. Phyllotrox sulcirostris, sp. n.

Oblong-ovate, finely pubescent, the prothorax dull, the rest of the surface shining; black, the antenn (the

club and outer joints of the funiculus excepted) and legs testaceous, the elytra brownish-testaceous, with

the suture narrowly infuscate. Rostrum nearly as long as the prothorax, densely punctate, distinctly

sulcate on the upperside towards the base. Prothorax a little broader than long, rounded at the sides,

narrowed and constricted in front, and very slightly narrowed at the base, closely punctate. Llytra oval,

deeply punctate-striate, the interstices convex and closely, minutely punctate. Intermediate tibix

dilated at the outer apical angle.

Length 2 millim.

Hab. Guatemaua, Calderas (Champion); Panama, Volcan de Chiriqui (Champion).

One specimen from each locality. Very like one of the varieties of P. suturalis,

but with the rostrum distinctly grooved at the base above. The Colombian P. rugi-

rostris and P. subopacus, Schauf., are also described as having a sulcate rostrum, but

differ in other respects from the present species.

11. Phyllotrox maculicollis, sp. n.

Oblong-ovate, shining, finely pubescent; black, the tip of the rostrum and a large spot on each side of the

prothorax behind rufo-testaceous, the antenne (the club excepted), abdomen, legs, and elytra testaceous,

the suture of the latter narrowly black almost to the apex. Rostrum shorter than the prothorax,

rugulosely punctate. Prothorax transverse, rounded at the sides, more narrowed in front than behind,

densely, rugulosely punctate. Elytra oblong- ovate, finely seriate-punctate, the interstices flat, each

with a row of punctures similar to those of the striw. Legs stout, the intermediate tibie dilated at the

outer apical angle. Pygidium visible, shallowly foveate.

Length 2 millim.

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

One specimen, probably a male. Separable from most of the allied forms by the

interstitial punctures of the elytra being precisely similar to those of the striz.

12. Phyllotrox fiavescens, sp.n. (Tab. IX. fig. 2.)

Ovate, shining, flavo-testaceous, very finely pubescent. Rostrum faintly sulcate, about as long as the

prothorax, finely punctured. Prothorax convex, as long as broad, considerably narrowed in front and

subparallel behind, sparsely, very minutely punctate. Elytra ovate, at the middle nearly twice as wide

as the prothorax, very minutely seriate-punctate, the interstices quite flat and each with an excessively

minute row of punctures. Legs slender.

Length 14 millim.

Hab. British Honpuras, Belize (Blancaneauz).

One specimen. Not unlike P. pallidus, Fahr., from St. Vincent, W.I., but with

the punctuation of the upper surface much less distinct, the prothorax narrower, and the

legs more slender.

13. Phyllotrox depressus, sp. n.

Oblong-ovate, somewhat depressed, shining, glabrous; piceous, the prothorax rufo-testaceous at the hase, the

scape and funiculus of the antenne, the legs, the apex of the abdomen, and the elytra testaceous,

the suture of the latter faintly infuscate in front. Rostrum fully as long as the prothorax, closely,

finely punctate. Prothorax transverse, somewhat rounded at the sides, a little more narrowed in front

than at the base, closely, finely punctate. Elytra slightly wider than the prothorax, oblong; the

surface punctured like that of the prothorax, the obliterated strie, however, showing through from

beneath. Legs stout, the four hinder tibiz acutely produced at the outer apical angle. Pygidium

visible, unimpressed.

Length 27 millim. (<d.)

Hab. GuateMata, Cerro Zunil (Champion).

One specimen, perhaps abraded. More depressed than any of the other Central-

American forms, and with the elytra confusedly punctured, the strie, however, showing

through from beneath. This insect has much the facies of a Derelomus.

TERIOLTES, gen. nov.

Rostrum elongate, slender, the scrobes rapidly descending and reaching the lower anterior margin of the

eyes ; eyes rounded, prominent, somewhat widely separated ; antennee elongate, inserted at about one-

third from the apex of the rostrum, the funiculus 7-jointed—joint 1 obconic, stout, much longer than

broad, 2 smaller and shorter, 3-7 transverse, becoming very gradually wider, 7 much narrower than the

club,—the latter ovate and acuminate, with the sutures not very distinct; head very little produced

behind the eyes; prothorax convex; scutellum very small; elytra ovate, covering the pygidium ;

anterior coxe contiguous; prosternum moderately long (2. cirewmdatus) or very short (Z'. nigripennis) ;

ventral segments 1 and 2 connate, 3 and 4 very short, the sutures straight; femora more or less

thickened, unarmed ; tibie narrow, straight, simply truncate and unarmed at the apex; tarsi rather

slender, sparsely villose beneath, the third joint bilobed, the claws simple, divergent ; body oblong-ovate,

very sparsely pubescent.

The two small species referred to this genus are very closely related to Phyllotrox,

but they cannot be included in it on account of the structure of the antenne, the

funiculus being relatively longer and the outer joints much narrower than the club.

The only other nearly allied American genus known to me is Ophthalmoborus

(Anthobius olim), which has the head more prolonged behind the eyes, the antenne

inserted at the middle of the rostrum, and the funiculus formed as in Phyllotroz.

Xanthus, Dietz, is perhaps an allied form, but it is described as having a freely

exposed pygidium, the antennal club loosely articulate, &c.

TERIOLTES.—BOTANEBIUS. 147

1. Terioltes circumdatus, sp.n. (Tab. IX. figg. 3, 3a, 6.)

Shining, extremely finely pubescent, testaceous, the antennal club, a large patch on the disc of the prothorax,

and the sides and apex of the elytra black. Head flattened and somewhat coarsely punctured between

the eyes; rostrum very feebly curved, longer than the prothorax, rugulose, dull, and shallowly sulcate

above. Prothorax convex, a little longer than broad, distinctly margined at the base and apex, rounded

at the sides, constricted and much narrowed in front and slightly narrowed behind; the surface very

minutely punctate. Elytra much wider than the prothorax, ovate, punctate-striate, the interstices

feebly convex and extremely minutely punctulate. Legs comparatively slender.

Length 2? millim.

Hab. Panama, Boquete in Chiriqui 3500 feet (Champion).

One specimen.

. 2. Terioltes nigripennis, sp.n. (Tab. IX. figg. 4, 4a.)

Very shining, extremely finely pubescent, ferruginous, the eyes and elytra black. Head sparsely punctured

between the eyes, which are large; rostrum curved, not longer than the prothorax, rugulosely punctate.

Prothorax about as long as broad, convex, much narrowed in front, the sides rounded anteriorly and

almost straight behind; the surface minutely punctate. Elytra ovate, much wider than the prothorax,

punctate-striate, the interstices flat and very minutely punctulate. Legs comparatively stout.

Length 2% millim.

Hab. Guaremaa, Senahu in Vera Paz (Champion).

One specimen. Differs from 7. circumdatus in the curved, shorter rostrum, which

is not sulcate above, the shorter antenne, the larger eyes, the stouter legs, the shorter

prosternum, and dissimilar coloration. This insect has much the facies of an Apzon.

Group ANTHONOMINA.

Anthonomides, Lacordaire ; Anthonomini, Leconte, Dietz.

This group is closely related to the Erirrhina, and includes the well-known genus

Anthonomus and various allied forms, differing chiefly from the Errirhina in the toothed

or appendiculate tarsal claws, the eyes, too, in most of the species being prominent.

The section Rhynchznides (Orchestides, Lacord.) is represented by a single peculiar

monotypic genus. ‘The North-American species have been exhaustively monographed

by Dietz [‘Trans. Am. Ent. Soc. xviii. pp. 177-276, tabb. 5-7 (1891)], who recognizes

130 as distinct. About 100 species are now known from Central America, and with

few exceptions these are treated as new, two only having been previously described

from our region.

funiculus, a very uneven prothorax, broad, gibbous, tuberculate elytra, and short legs,

the femora each with a single tooth, the anterior and intermediate tibie with a strong

claw, the tarsal claws with a long tooth. Schénherr and Lacordaire omit to note the

form of the scrobes, which (in B. gibbosus) are short and evanescent, as in Cionistes.

We possess three specimens of this species, varying in size and in the development

of the prominences on the upper surface; one of them (? ¢) has the rostrum densely

pubescent to near the tip. In the larger examples the posterior lobe of the prothorax

is emarginate in the middle.

Dr. Heller has been kind enough to compare one of the Honduras examples with

the type, which is of the male sex.

CIONISTES.

Cionistes, Dietz, Trans. Am. Ent. Soc. xviii. p. 187 (1891).

A genus hitherto including a single species from California. The Guatemalan insect

now added agrees with it in having short, descending, evanescent scrobes, a 7-jointed

funiculus, and appendiculate tarsal claws, as well as in general form, &c.; but the

elytra in C. brevis are somewhat lobed at the base and without tubercles.

1. Cionistes brevis, sp.n. (Tab. IX. figg. 6, 6a, ¢.)

Broadly obovate, convex, comparatively short, slightly shining, piceous, the anterior margin of the prothorax,

and the antenne and legs in part, ferruginous ; clothed with fine greyish or fuscous pubescence, which

sometimes becomes ochreous at the sides of the prothorax and at the base of the elytra. Head rugulose,

the eyes not very prominent and narrowly separated above; rostrum rather stout, moderately curved, a

little longer than the head and prothorax, rugosely punctured and longitudinally wrinkled, smoother and

shining at the tip, the antenne (¢) inserted at about two-fifths from the apex, joint 1 of the funiculus

as long as 2-4 united, joints 3-7 transverse. Prothorax short and broad, rounded at the sides, strongly

constricted and much narrowed in front and also narrowed behind, the base bisinuate, the surface densely

punctate. Elytra much wider than the prothorax, widening from the base to a little beyond the middle,

rather short, somewhat lobed in front on each side of the scutellum, the humeri swollen, rounded ;

deeply punctate-striate, the interstices convex and faintly rugulose. Legs comparatively short and stout ;

anterior femora strongly clavate, rugose, and armed with a long triangular tooth, the intermediate and

hind femora also with an acute tooth, that on the hind pair short; anterior tibise rugose, stout, sinuous

within ; tarsal claws with a broad tooth.

ACHIA, gen. nov.

Achia, Pascoe, in litt.

Head strongly constricted behind the laterally placed, prominent eyes, which are oval when viewed in profile ;

rostrum moderately long, tapering or cylindrical, the scrobes gradually descending to the lower edge of

the eye; antenne inserted towards the apex of the rostrum in the d, further back in the 9, the

funiculus 7-jointed, the club ovate; prothorax transverse, constricted and tubulate in front, sinuate at

the base ; elytra short and broad, gibbous or convex, covering the pygidium ; prosternum extremely short,

emarginate in front; ventral segments 3 and 4 a little shorter than 2; legs short and stout, anterior

femora greatly incrassate, and armed with two triangular teeth, the inner one large, the other femora

with an acute tooth; anterior tibie strongly curved and unguiculate, the others almost straight, the

intermediate pair mucronate ; tarsal claws with a long tooth ; body densely pubescent, Cioniform.

This genus includes three species from within our limits and other undescribed

South-American forms, which are readily distinguishable by their strongly constricted

head, the eyes appearing, at first sight, to be placed at the sides of the rostrum,

as in Dioptrophorus, &c., of the group Anchonina. The anterior femora and tibie

are shaped much as in Prionomerus. The Mexican dA. rhombifera is very like a

Cionus, and the resemblance is further accentuated by the dark patch at the base of

the elytra.

1. Achia rhombifera, sp.n. (Tab. IX. figg.7, 7a, ?.)

Broad-ovate, very robust, densely rugulose, opaque, piceous or ferruginous, the antenne (the club excepted)

and legs (the anterior femora and tibi, in part, excepted) testaceous ; densely clothed with short, fine,

pale greyish pubescence, which becomes ochreous in places, intermixed with a few short curled hairs ;

the elytra with a large, common, rhomboidal patch at the base, extending on to the posterior portion

of the prothorax (but not on to the scutellum), purplish-black or fulvous, and with a large apical patch

and the humeri ochreous or reddish-ochreous, the prothorax with a transverse curved space on the disc

behind similarly coloured, the head and rostrum also with ochreous pubescence, the pubescence on the

Ovate, convex, closely rugulose, opaque, piceous or rufo-piceous, the tip of the rostrum, the antenne, the base

of the intermediate and hind femora, the tibie, and tarsi more or less testaceous ; densely clothed with

greyish-ochreous pubescence, the prothorax with a darker patch on each side of the disc, leaving a pale

median vitta, the elytra with a large, common, rhomboidal, fulyous or obscure ferruginous patch at the

parallel in their basal half, the rhomboidal patch not extending on to the prothorax.

3. Achia discifera, sp.n. (Tab. IX. fig. 9, ¢.)

Ovate, densely rugulose, opaque, rufo-piceous, the antenne, the tibive and tarsi in part, and the base of the

intermediate and hind femora ferruginous or testaceous, the rostrum black at the tip; thickly clothed

with greyish-ochreous pubescence, that on the head, rostrum, prothorax, and under surface coarser and

squamiform ; the elytra with a large, common, transverse, oval, brownish-ferruginous patch at the base,

this being streaked with ochreous on the third interstice, the other portion thence to the apex slightly

mottled with fuscous. Rostrum scarcely as long as the head and prothorax, cylindrical, bare and shining

at the tip, the antenne inserted at about one-third from the apex, joint 1 of the funiculus twice as long as 2,

tubulate in front, strongly sinuate at the base; elytra broad, covering the pygidium; prosternum

extremely short; legs short and stout; anterior femora greatly incrassate, gradually narrowing to the

base, and armed with two stout, triangular, approximate teeth, the inner one large and acute, and both

The above characters are taken from a single species from Guatemala that cannot

very well be placed in Anthonomus, on account of the enormously developed anterior

femora (which are very like those of Prionemerus, and not pedunculate at the base) and

the exserted head.

Dietz, Trans. Am. Ent. Soc. xviii. p. 188 (part.).

This genus includes a very large number of species, being especially well represented

in America north of Mexico, whence Dietz recognizes eighty-two as distinct, which he

places under nine subgenera, fifty-four of the former being referred to Anthonomus,

s. str. The Central-American forms, most of which are treated as new, are almost

equally numerous and of a very heterogeneous character, many of them differing greatly

in general facies, but not in structure. As adopted here, Anthonomus (after the exclu-

sion of the preceding genera, the characters of which have already been noticed) is

restricted to those species with the funiculus 7-jointed (various forms with a 6-jointed

funiculus are included by both Leconte and Dietz*), the tarsal claws toothed, the

posterior tibiae unarmed or simply mucronate at the apex, and the femora bi- or

unidentate, the hind pair sometimes unarmed. ‘The scrobes are usually lateral, but

they sometimes descend to beneath the lower limit of the eyes in the species with

a stout, curved, comparatively short rostrum (A. puncticeps &c.), and the length of the

antennal club is also variable, being long and loosely articulated in the forms with

long and slender antenne. .

To facilitate their identification, the Central-American species are here arranged

under “groups,” based mainly upon their general facies, rather than upon their

structure, all attempts ‘at briefly tabulating them by their essential characters only

having proved unsatisfactory, or of little practical value to the student.

A. Elytra more or less tuberculate or nodose, at least towards the base ;

autcrior femora much thickened, bi- or unidentate ; antennal club

faint, curved, whitish fascia towards the apex (the anterior fascie not extending beyond the fourth stria),

the coarser clothing of the prothorax tending to form vitte laterally. Head rugulose; rostrum feebly

curved, much longer than the head and prothorax, finely punctate and tricarinate, smoother and shining

Oblong, rufo-piceous, the rostrum (except at the tip), the antennex, the anterior femora and tibie in part, the

intermediate and hind legs, and the apex of the abdomen ferruginous ; clothed with a scattered pallid or

ochreous squamiform pubescence, which is coarser on the prothorax, the larger elevations on the elytra

each with a dense cluster of long, erect, ochreous setee and the ninth interstice also with a small cluster

of sete beyond the middle; the pubescence of the under surface whitish. Head rugulose, the eyes small,

rounded, prominent ; rostrum slender, shining, feebly curved, very elongate, tricarinate in its basal half,

one small; intermediate and hind femora each with a small tooth ; tarsal claws with a long tooth.

Length 33, breadth 13 millim. (Q.)

Hab. Mexico (Salié).

One specimen only of this curious species has been received. It is readily recog-

nizable by the large setigerous tubercles on the elytra and the angularly projecting

humeri. A. seatuberculatus somewhat resembles the N.-American Tuchypterus

quadrigibbus (Say); but in that insect the hind tibie are unguiculate at the apex,

the anterior femora are more feebly clavate, the rostrum is stouter, and the elytral

elevations are fewer in number and without sete.

7. Anthonomus nodifer, sp.n. (Tab. IX. figg. 23, 234, 3.)

Oblong, rugulose, opaque, rufo-piceous, the rostrum, antenne (the club excepted), and legs testaceous, the

femora mottled with fuscous at the middle; thickly clothed with small scales, which are mostly ochreous

in colour, the elytra with a few small whitish spots and with oblong bare spaces on each interstice, the

larger elevations setose, the squamosity of the prothorax somewhat coarse and mottled, the legs with rather

long hairs. Rostrum feebly curved, slender, considerably longer than the head and prothorax, finely

punctate and faintly carinate, smoother and shining at the tip, the antennz inserted at one-third from

Oblong, rather narrow, dull, rugulose, rufo-piceous, the scape of the antenne and the legs in part testaceous

or ferruginous; thickly clothed with a fine, squamiform pubescence, which becomes coarser on the

prothorax, the pubescence in great part ochreous, the prothorax with indications of three paler lines on

disc and the elytra with a few small scattered cinereous spots, the latter with bare oblong spaces on each

interstice and the elevations on the second each with a cluster of long sete. Rostrum slender, curved,

considerably longer than the head and prothorax, finely punctate and tricarinate, smoother at the tip,

the antenne inserted at about one-third from the apex, joint 1 of the funiculus twice as long as 2; eyes

prominent. Prothorax broader than long, rounded at the sides, constricted and much narrowed in front

Two males and two females. Very similar to A. canescens, but smaller and less

elongate, and with finer pubescence; and differing from A. albolineatus in the absence

of the line of dense white pubescence along the suture at the base. It is possible that

these three insects may prove to be forms of one very variable species. A. tncanus also

resembles the North-American A. albopilosus, Dietz, but it has the prothorax convex

and more coarsely punctured, the elytra a little depressed towards the base, with the

anterior margin more raised, &c.

A common insect in Southern Mexico, Guatemala, &c., and recognizable by its

subovate form, shining black or brassy-black surface, and very sparse white or

yellowish pubescence, which is easily abraded and in fresh specimens is clustered into

a few spots on the elytra. The base of the femora and of the tarsi and the apical

half of the tibiz are usually testaceous. The femora have each a small tooth, but

this is absent in one of the four examples from Chontales. The prothorax is coarsely,

rather sparsely punctate. The type has been lent us for examination. Sixty examples

of A. mexicanus are contained in our collection.

21. Anthonomus orichalceus, sp. n.

pubescence at the base on each side within the humeral angles, for the rest bare, the interstices smooth ;

tibie, tarsi, and the base of the femora rufo-testaceous ; femora each with a small tooth; anterior and

intermediate tibiee strongly sinuate within.

subparallel at the base; deeply punctate-striate. Femora each with a small tooth; anterior and inter-

mediate tibize strongly sinuate within ; tarsal claws with along tooth.

Var. The prothorax with three narrow vittz, and the elytra with the alternate interstices in part, clothed

with whitish, and the rest of their surface with ochreous, pubescence.

Short-ovate, convex, eneo-piceous, faintly shining, the antenne (the club excepted) testaceous, the base of

the femora, and the tibie and tarsi in part, sometimes obscure ferruginous; the elytra with a small

patch of dense, white, squamiform pubescence on the suture at the base, extending forward over the

scutellum, the rest of the upper surface bare; the under surface sparsely clothed with white pubescence,

which becomes denser at the sides. Head almost smooth, foveate above the eyes, the latter narrowly

separated ; rostrum curved, stout, slightly longer than the head and prothorax, coarsely seriate-punctate

and 5-carinate, confusedly punctured and shining at the tip, the sc:obes descending to beneath the

eyes, the antenne inserted at about two-fifths from the apex, joint 1 of the funiculus nearly as long

as 2-4 united, 3-7 short and transverse. Prothorax transverse, rounded at the sides, narrowed and

constricted in front, strongly bisinuate at the base, closely, coarsely punctate. Elytra considerably wider

than the prothorax, short, parallel at the base, the humeri a little swollen, the suture depressed behind

the scutellum ; punctate-striate, the interstices smooth and more or less convex. Femora each with an

acute tooth; tarsal claws with a long tooth.

Length 2, breadth 1,4) millim. (¢ 9.)

Hab. Mexico, Tapachula in Chiapas (Hoge); Guatemaua, El Jicaro in Vera Paz

(Champion).

Four specimens. The chief characters of this species are its short-ovate form, the

rugose rostrum, and the small patch of dense white squamiform pubescence on the suture

of the elytra at the base, the rest of the upper surface (the scutellum excepted) being

bare. The eyes are more approximate than in A. mexicanus, and less prominent than in

A. albopictus. The scrobes are lower down than usual, descending to beneath the eyes.

A. albopictus-group.

30. ‘Anthonomus albopictus, sp. n.

Ovate, rather broad, dull, black, the apex of the antennal scape rufo-testaceous, the intermediate and hind

femora obscure ferruginous at the base; clothed with a short, fine, very sparse, ochreous pubescence, and

with a few very small widely scattered clusters of whitish scales—one on the scutellum, one near each

shoulder, and a few on the disc of the elytra being the most conspicuous; the under surface squamose,

the vestiture whitish and becoming very dense at the sides; the legs with piliform and broad scales

intermixed. Head rugulose and suleate between the eyes, and feebly constricted behind them, the eyes

very prominent and narrowly separated; rostrum slender, curved, much longer than the head and

prothorax, shining, shallowly seriate-punctate, almost smooth in its apical half, the antenne inserted

about the middle, joint 1 of the funiculus nearly as long as 2—4 united. Prothorax transverse, rounded

at the sides, much narrowed and constricted in front, densely, rugosely punctate. Elytra convex,

comparatively short, a little wider than the prothorax, subparallel towards the base, the humeri rounded ;

deeply punctate-striate, the interstices almost flat and densely rugulose. Legs long, rugose; femora

each with an acute tooth, the anterior pair moderately clavate; anterior and intermediate tibie sinuate

on their inner edge ; tarsal claws with a long tooth.

Length 24, breadth 13 millim. ( 9.)

Hab. Mexico, Ventanas in Durango (/ége).

One specimen. Recognizable by its short, broadly ovate form, rugosely punctured

prothorax, rugulose elytra, and peculiar vestiture. It is possible, however, that in

fresh examples the entire upper surface is squamose ; but this can hardly be the case,

as our insect has a short ochreous pubescence between the small scattered clusters of

coarse whitish scales. ‘The sculpture of the prothorax is as coarse as in that of the

North-American A. nigrinus, Boh.

scrobes deep, descending to beneath the eyes, and extending sinuously forward to near the apex; antenne

inserted at the middle of the rostrum, joints 3-7 of the funiculus very short, closely articulated, and

widening outwards, 1 twice as long as 2, 7 almost forming part of the club, the latter stout. Prothorax

convex, broader than long, slightly rounded at the sides, and gradually narrowing from a little before the

base to the apex, not constricted in front, sparsely, finely punctate. Elytra much wider than the

prothorax, short, gibbous, the humeri obtuse; finely and lightly punctate-striate, the interstices smooth

and shining. Legs rather short ; femora each with a small tooth; anterior tibiz not hollowed within;

tarsal claws with a very short tooth.

Length 2, breadth 1 millim. ( ?)

Hab. Panama, Bugaba (Champion).

One specimen only, somewhat immature and abraded, of this curious species has

been obtained. It is probably black, and has white pubescence on the scutellum

and under surface, when mature and in good condition. The head is coarsely, and

the prothorax and elytra are finely, punctured; the rostrum is very stout and

curved, with the scrobes deep and descending (the insect in this respect approaching

A. alboscutellatus) and continued forward; and the tarsal claws have a very short

tooth.

inserted at about two-fifths from the base, joint 1 of the funiculus elongate, as long as 2-4 united.

Prothorax broader than long, rounded at the sides, much narrowed and feebly constricted in front, strongly

bisinuate at the base ; the surface closely impressed with moderately coarse, round punctures, in each of

which there is a blue scale. Elytra a little wider than the prothorax, slightly rounded at the sides, the

humeri swollen, but obtuse ; punctate-striate, the interstices rugulose and almost flat. Pygidium covered.

Legs long and rather stout ; all the femora strongly clavate, and each with an acute triangular tooth, the

tibie sinuate within; tarsal claws with a long tooth.

Length 31, breadth 14 millim. (@.)

Hab. Guatemata, Mirandilla, Pacific slope (Chamvion).

The fifteen specimens received from within our limits merely differ from a N.-

American example before me in having the rostrum a little smoother and more shining.

The red coloration on the elytra varies in extent—in some specimens leaving the suture

only black, and in others reduced to a large humeral patch ; and the legs are usually

in part ferruginous. Numerous allied forms inhabit the United States.

flab. Panama, Volcan de Chiriqui, Caldera (Champion).

Hight specimens, varying a good deal in colour, some of them being almost entirely

ferruginous, the legs included. The chief characters of A. sulcipygus are the sulcate

and exposed pygidium in the male, the very deeply striate, somewhat gibbous elytra,

the sparse pubescence, and the large and prominent eyes. It belongs to the subgenus

rostrum and antenne, the dark elytral suture (the triangular patch at the base, at

most, faintly indicated), and the sharply, triangularly dilated hind tibie in the male,

the dilatation arising beyond (instead of before) the middle. The pubescence is

rather sparse above, not hiding the sculpture.

the anterior pair long, the body testaceous.

LISTRORRHYNCHOUS, gen. nov.

Rostrum stout and rugose for about one-third of its length, and thence to the tip smooth and slender, the

scrobes descending to the lower limit of the eyes; antennee inserted at the apex of the incrassate portion

oblong-ovate and somewhat loosely articulated ; anterior legs much longer than the others; anterior and

intermediate tibise unguiculate, the posterior pair unarmed; tarsal claws with a long tooth; the other

characters as in Anthonomus.

The single species referred to this genus bears much the same relation to Anthonomus

as Oxystoma does to Apion, except that the abrupt narrowing of the rostrum is more

pronounced. The specimens obtained appear to be all of the same sex, probably

females. The peculiar form of the rostrum is a remarkable character, and hitherto

unknown amongst the Anthonomids.

1. Listrorrhynchus subulatus, sp. n. (Tab. XI. figg. 11, 11a, o*.)

Subovate, ferruginous, the rostrum, the outer half of the antenna, the knees, the tarsi, and the upper outer

narrow in front of the anterior coxee; legs subequal in length, the femora unarmed, all the tibie

unguiculate, the tarsal claws with a long tooth ; the other characters as in Anthonomus.

The single species referred to this genus cannot very well be included in Anthonomus.

Following Dietz’s arrangement, it should come near Tachypterus *.

1. Dietzia bifasciata, sp.n. (Tab. XI. figg. 12, 12a, 4, 3.)

Subovate, rather dull, ferruginous, the head, the prothorax (a transverse space on the disc in front excepted),

a transverse median fascia on the elytra and a sinuous narrower one before the apex, and the meta-

sternum, infuscate or piceous; finely pubescent, the elytral interstices each with a row of short decumbent

squamiform sete, and the prothorax with squamiform pubescence on the disc at the base, the vestiture

ochreous on the light-coloured portions of the surface and darker elsewhere, that of the scutellum and

under surface paler. Head closely punctured; rostrum rather stout, feebly curved, shining, seriate-

punctate at the sides, smooth along the middle, the antenne inserted at about one-third from the apex,

joint 1 of the funiculus stout, twice as long as 2, 3-7 transverse and closely articulated. Prothorax

broader than long, moderately rounded at the sides, a little more narrowed in front than at the base, the

latter very feebly sinuate, the surface densely, rugulosely punctate. Elytra one-half wider than the pro-

thorax, short, sinuate at the base, the sides parallel in front, the humeri rather prominent; punctate-striate,

the interstices convex and punctulate. Legs rather short; femora deeply excised towards the apex

beneath (so as to appear angularly dilated when viewed in a certain position); anterior tibie feebly

sinuate within.

Length 23, breadth 13 millim. (<¢.)

Hab. Paxama, Bugaba (Champion).

One specimen. Readily recognizable by the bifasciate, broad, subcordate elytra, the

unarmed femora, the unguiculate posterior tibie, &c. The anterior legs are very little

longer than the others. The claw at the apex of the hind tibie is extremely small

and not easily seen.

PSEUDANTHONOMUS.

Pseudanthonomus, Dietz, Trans. Am. Ent. Soc. xviii. p. 248 (1891) (part.).

To this genus are referred all the Central-American Anthonomids with a 6-jointed

funiculus, long, lateral or descending scrobes, unidentate or simple femora, mucronate or

unarmed posterior tibie, and toothed tarsal claws. Dietz attaches greater importance

to the position of the scrobes than to the number of joints in the funiculus; but the

first-mentioned character cannot be relied upon, the scrobes varying in position, as

might be expected, according to the length, curvature, and thickness of the rostrum,

and this is also the case in Anthonomus. Pseudanthonomus includes comparatively

few species, and they are all of small size. P. nubilosus has very strongly unguiculate

anterior tibie, and it may have to be separated eventually from this genus.

whitish and condensed in places, forming a faint median vitta on the prothorax and several conspicuous

spots on the elytra—one behind the scutellum, one at the base near the shoulder, and two on each of the

alternate interstices, these latter forming two curved fasciee beyond the middle; the squamosity dense at

the sides beneath. Head rugulose; rostrum (3) moderately curved, slightly longer than the head and

prothorax, rugulose, smoother at the tip, (Q ) a little longer and smoother, the antennz inserted at two-

fifths from the apex in the ¢ and at the middle in the 9, the scrobes lateral, shallow, the funiculus

6-jointed, 1 nearly as long as 2-4 united. Prothorax transverse, rounded at the sides, much narrowed

PSEUDANTHONOMUS. 197

One specimen. Allied to the N.-American P. crategi (Walsh) (a specimen of which

has been sent us by Mr. Wickham), but less elongate, the elytra being relatively

shorter and broader, the rostrum longer, the pubescence evenly distributed. The

broad elytra and sparse yellowish pubescence separate P. rufotestaceus from the other

similarly-coloured allied Central-American forms.

6. Pseudanthonomus meridionalis, sp. n.

Subovate, ferruginous, the eyes and antennal elub black; thickly clothed with fine greyish pubescence, the

vestiture of the scutellum and under surface whitish. Head rugulosely punctate, the eyes very prominent

and rather narrowly separated ; rostrum (¢) stout, moderately curved, about as long as the prothorax,

rugulosely punctate, smoother and shining beyond the middle, ( @ ) slightly longer, the scrobes rapidly

descending to beneath the eyes; antennew inserted at (@) or slightly before (¢) the middle of the

rostrum, the funiculus 6-jointed, joint 1 stout, 2-6 small and closely articulated, 2 much longer than 3,

4 very short, 5 and 6 a little longer than 4. Prothorax transverse, rounded at the sides, narrowed and

constricted in front, strongly sinuate at the base, densely punctate. Elytra short, convex, much wider

than the prothorax, subparallel before the middle; deeply punctate-striate, the interstices convex and

faintly punctulate. Legs rather slender, the femora moderately clavate and each with a minute tooth,

that on the hind pair almost obsolete; anterior tibie sinuate within ; tarsal claws with a long tooth.

Length 13-2, breadth 1 millim. (¢ @.)

Hab. Panama, Volcan de Chiriqui (Champion).

Seven specimens. Very like the N.-American P. crategi (Walsh), but less elongate,

the elytra relatively shorter, the rostrum smoother beyond the middle. The shorter

and stouter rostrum, with more rapidly descending scrobes, the finer, closer, and

greyish pubescence, and the narrower general shape separate it from P. rufotestaceus.

7. Pseudanthonomus griseipilis, sp. n.

Subovate, obscure ferruginous or piceous, the rostrum sometimes black, the legs ferruginous, with the femora

usually blackish in their outer half; thickly clothed with greyish pubescence. Head rugulosely punctate,

the eyes prominent and somewhat narrowly separated; rostrum (3) moderately stout, feebly curved, a

little longer than the prothorax, rugulosely punctate to near the tip, (2) more elongate, the antenne

inserted at (Q) or slightly before (¢) the middle, the funiculus 6-jointed, joint 1 stout, 2 a little longer

than 3, 3-6 subequal in length. Prothorax, elytra, and legs as in P. meridionaks.

Length 2-2,4,, breadth 1 millim. (¢ 2.)

Hab. Guaremaua, San Geronimo, San Juan, and Cahabon in Vera Paz (Champion).

Five specimens. This species differs from P. meridionalis in having the rostrum

more rugose, and also longer in the female, the joints 2-6 of the funiculus less closely

articulated, 3-6 subequal in length.

8 Pseudanthonomus nubilosus, sp.n. (P. nudilus, Tab. XI. fige. 16, 16a, 3 .)

Oblong-ovate, narrow, ferruginous, the antennal club piceous or black ; sparsely clothed with rather coarse,

white or yellowish-white pubescence, which is condensed along the middle and sides of the prothorax

and on the scutellum, and forms definite markings on the elytra—a short streak at the base of the suture,

a spot at the shoulder, an oblique fascia a little beyond the middle, and a transverse, interrupted fascia

towards the apex. Head rugulosely punctate, the eyes rather small; rostrum stout, curved, a little

longer than the prothorax, rugulose, smooth and shining at the extreme tip, the scrobes rapidly de

scending ; antenne inserted at about one-third from the apex of the rostrum, the funiculus 6-jointed,

joints 9-6 short. Prothorax transverse, narrowing almost from the base, feebly constricted in front,

densely, somewhat coarsely punctate. Elytra a little wider than the prothorax, oblong, subparallel in

their basal half; deeply punctate-striate, the interstices convex, finely punctulate, and shining. Femora

unarmed ; tibiee sinuous within, the anterior pair strongly unguiculate, the intermediate and hind pairs

also with a small hook at the inner apical angle; tarsal claws almost simple.

Length 2, breadth 1 millim. (¢.)

Hab. Mexico, Omilteme in Guerrero 8000 feet (HZ. H. Smith); Guatemaa, Quezal-

tenango 7800 feet (Champion).

Two specimens. This insect so closely resembles the North-American Anthonomus

nubilus, Lec. (which belongs to Pseudanthonomus, as adopted here), that it was at first

mistaken by me for the male of that species, from which it may be separated, however,

by the very strongly unguiculate anterior tibie, the stouter rostrum, and the less

rounded sides of the prothorax.

9. Pseudanthonomus cretaceus, sp.n. (Tab. XI. figg. 17, 17 a.)

Elongate-ovate, narrow, nigro-piceous, the elytra, rostrum, and femora obscure ferruginous, the antenne (the

club excepted), tibia, and tarsi rufo-testaceous ; thickly clothed with coarse, oval or rounded, whitish

scales, the squamosity of the prothorax and elytra mottled with pale brown. Head rugulosely punctate,

foveate above the eyes, the latter small and not prominent; rostrum curved, comparatively stout, not

longer than the head and prothorax, rugulose, smoother at the tip, the serobes deep, descending to beneath

the eyes; antenne inserted at about two-fifths from the apex of the rostrum, the funiculus 6-jointed,

joint 1 as long as 2 and 3 united. Prothorax transverse, rounded at the sides, gradually narrowing from

a little before the base to the apex, densely punctate. Elytra oblong, convex, not much wider than the

prothorax, the humeri obtuse ; coarsely punctate-striate, the interstices narrow, convex, and faintly

punctulate. Legs rather stout, squamose ; anterior femora with a very minute tooth, the others un-

armed ; anterior tibia sinuate within; tarsal claws with a short, slender tooth.

Length 21, breadth 1,5 millim. (d ?)

Hab. Mexico, near the city (H. H. Smith),

One specimen. Very like a narrow, elongate Zychius. ‘The coarse squamosity, the

6-jointed funiculus, and general shape distinguish it at once from all the other allied

Central-American forms.

10. Pseudanthonomus hispidus, sp.n. (Tab. XI. figg. 18, 18a, 2.)

Subovate, rufo-piceous, the rostrum ferruginous at the base and black at the tip, the legs ferruginous; densely

elothed with yellowish-grey pubescence, that on the upper surface and legs intermixed with very long,

pallid, pointed, erect: sete, which are serially arranged on the elytra. Rostrum strongly curved, stout,

about as long as the head and prothorax, seriate-punctate, the scrobes descending to beneath the eyes,

which are transverse and prominent; antennse inserted at the middle of the rostrum, the funiculus

6-jointed. Prothorax transverse, narrowed and slightly constricted in front, strongly sinuate at the

pase, densely punctate. Elytra much wider than the prothorax, short, subparallel before the middle,

somewhat lobed at the base, the humeri prominent; punctate-striate, the interstices convex and rugulose.

Prosternum emarginate in front. Femora unarmed; tibis without claw at the apex; tarsal claws with

a moderately long tooth.

Length 1,%,, breadth 1 millim. (@.)

Hab. Guatemaua, San Gerdénimo (Champion).

One specimen. This insect agrees with Anthonomus (Anthonomocheta) heterogenus,

Dietz, of the United States, in having very long, erect sete intermixed with the dense

pubescence; but the funiculus is 6-jointed, the rostrum is stout, the eyes prominent, &e.

NEOMASTIX.

Neomastix, Dietz, Trans. Am. Ent. Soc. xviii. p. 254 (1891).

The two species here referred to this genus, hitherto including two minute forms

from the Southern United States, possess the principal characters assigned to it by

Dietz, viz. a 5-jointed funiculus and an ovate antennal club. In one of them (WN. setulosus)

the tibie are unarmed at the apex, and in the other (WV. concolor) the femora are feebly

unidentate.

1. Neomastix concolor, sp. n. (Tab. XI. figg. 19, 194, 2, 3.)

Subovate, shining, rufo-testaceous, the eyes black; sparsely clothed with rather long yellowish pubescence,

which is subserially arranged on the elytra. Head rugulose, the eyes large, but not prominent, somewhat

narrowly separated; rostrum rather stout, feebly curved, of the same length as the prothorax, dull and

rugulose, shining at the tip, the scrobes descending to the lower edge of the eyes; antenne inserted before

the middle of the rostrum, joint 1 of the funiculus stout, 2-5 small, 2 and 3 subequal in length, 4 and 5

shorter and transverse, the club large and ovate. Prothorax short, subconical, constricted before the apex,

densely, rugulosely punctate. LElytra much wider than the prothorax, convex, subparallel before the

middle, the humeri a little swollen; coarsely and deeply punctate-striate, the interstices convex, each

with a row of minute punctures. Legs slender; femora moderately clavate, each with a minute tooth;

anterior and intermediate tibi sinuate within, and unguiculate at the apex, the hind tibie straighter

and unarmed ; tarsal claws with a long tooth.

Length 14, breadth 1 millim. (<¢.-)

Hab. Guatemata, Duefias (Champion).

One specimen. Not unlike some of the European species of the genus Nanophyes

(which also have a 5-jointed funiculus), but easily separable therefrom by the toothed

claws, the well-developed scutellum, &c.

2. Neomastix setulosus, sp.n. (Tab. XI. figg. 20, 20a, 2.)

Subovate, piceous, the legs in great part ferruginous ; thickly clothed with white pubescence, with intermixed,

curled, erect, squamiform, white sete, which are coarse and prominent on the elytra, and arranged in a

single series on each interstice; the legs with curled squamiform hairs. Rostrum rather slender, feebly

curved, about as long as the head and prothorax, slightly widened at the tip, rugulose, the scrobes lateral,

descending to the lower edge of the eyes, the antenne inserted at the middle, joint 1 of the funiculus

stout, 2-5 small, the club ovate and moderately large; eyes very prominent, narrowly separated.

the prothorax, subparallel towards the base, the humeri not prominent; deeply punctate-striate, the

interstices very narrow and convex. Legs short and comparatively slender, the femora feebly clavate

and unarmed, the tibie straight on their inner edge and without claw at the apex ; the tarsal claws with

a short tooth.

Length 1, breadth 3 millim. (g.)

Hab. Nicaragua, Chontales (Janson).

Three specimens, probably all females. This is the smallest Curculionid we have

received from Central America. It is very like a minute Apion. The white sete on

the elytra are looped, tapering at the end.

Two species of this genus have been described, both from the Southern United

States, one of them extending into Mexico, whence another is now added. They are

wholly unlike the Anthonomids in general facies.

A single specimen of this species has been sent us from just within our limits.

2. Macrorhoptus mexicanus, sp.n. (Tab. XI. figg. 21, 21 ac.)

Black, the tibie and tarsi, and the base of the scape and of the funiculus, ferruginous ; densely clothed with

long, coarse, grey or brownish-grey scales, the prothorax brown on the disc and whitish at the sides,

the base of the elytra also whitish, the elytral interstices each with a series of short, fine, decumbent

sete. Prothorax and elytra densely punctate, the latter without strie. Anterior femora with a short

triangular tooth.

Length 21-22, breadth 15-14 millim.

Hab. Mexico, Guanajuato (Sallé).

Four specimens. Extremely like I. estriatus, but with the femora, and the antenne

in great part, black, the femoral tooth less acute. From M. hispidus, Dietz, from

Arizona *, it differs in having the vestiture a little less coarse, with the sete much

shorter and finer, and the femoral tooth not so sharp. J. meaicanus has much the

facies of some of the squamose Barids, amongst which it was placed in the Sallé

collection.

Orchestides, Lacordaire ; Rkynchenini, Bedel.

URSIDIUS, gen. nov.

Mandibles bifid at the apex ; rostrum strongly curved, moderately long, deflexed, the serobes short and lateral ;

antenne rather long, inserted towards the base of the rostrum, the scape slender, sinuous, clavate at the

tip, and reach backward to a little beyond the eye, the funiculus 7-jointed, the club elongate-ovate,

moderately stout, and loosely articulated ; eyes large, rounded (oval as seen from above), and moderately

prominent ; prothorax convex, about as long as broad, truncate at the base; scutellum very small ;

elytra much wider than the prothorax, oval ; prosternum exceedingly short in front of the anterior coxe

which are contiguous ; intermediate coxe narrowly, the posterior coxe more widely, separated ; meta-

sternum short, convex ; abdomen very convex, segments 1 and 2 connate at the middle, 3 and 4 subequal

in length, each shorter than 2; legs elongate; posterior femora exceedingly stout and sharply unidentate,

URSIDIUS.—LAMORCHESTES. 201

the others moderately clavate and unarmed ; tibie almost straight, unarmed at the apex ; tarsi with joint

3 strongly bilobed, 1 rather elongate, the claws divergent and appendiculate.

The remarkable species from which the above characters are taken has quite the

facies of a Halticid. In the saltatorial hind legs it approaches Rhychenus (Orchestes),

to which, however, Ursidius is not very closely allied. The genus appears to have

been unknown to Schénherr, though it also inhabits Brazil, and neither Kirsch nor

Faust has dealt with any insect of this kind in their various papers on S.-American

Curculionide.

1. Ursidius halticoides, sp.n. (Tab. XI. figg. 22, 22 a-e, 3.)

Oblong-ovate, dull, nigro- or rufo-piceous, the rostrum, antennex, and legs more or less, and sometimes the head

and prothorax also, ferruginous; clothed with a very fine, short, yellowish-grey or fulvous pubescence.

Head densely, rugulosely punctate, the eyes somewhat distant above and beneath; rostrum (3) mode-

rately stout, somewhat thickened basally, about as long as the prothorax, rugulosely punctate, laterally

sulcate towards the base, sparsely punctured at the tip, (@) a little longer and smoother; joint 1 of

the funiculus stout, obovate, nearly as long as 2 and 3 united, 2-7 slender, 3-5 longer than broad, 6 and 7

slightly shorter. Prothorax rounded at the sides, a little more narrowed in front than behind, densely,

minutely punctate. Hlytra moderately long, narrowing from a little below the shoulders, which are not

prominent, transversely depressed on the dise towards the base; faintly punctate-striate, the interstices

flat and densely punctulate.

Length 24-3, breadth 1-13 millim. (¢ 9.)

Hab. GuatemaLa, Purula in Vera Paz (Champion); Panama, Bugaba, Volcan de

Chiriqui, Petia Blanca (Champion).

Ten specimens, one only being from Guatemala, and varying a good deal in size and

colour. A nearly allied unnamed form from Brazil is contained in the Pascoe collection

at the British Museum.

LAMORCHESTES, gen. nov.

Rostrum stout, curved, slightly longer than the prothorax, without scrobes ; antennze inserted at the base of

the rostrum, straight, directed outwards, the scape very short, oval, the funiculus 7-jointed—joint 1

globose, stouter than the scape, 2-7 very slender, scarcely thickening outwards, 2 a little longer than

the scape, 3-7 much shorter,—the club ovate; eyes exceedingly large, oval, subapproximate above ;

prothorax small, strongly transverse, subtruncate at the base; scutellum triangular, small; elytra

broadly subquadrate, flattened ; pygidium visible ; prosternum extremely short in front of the anterior

cox, which are very narrowly separated; legs rather long and slender; femora equally and very

feebly clavate, unarmed; tibie straight, each unguiculate at the apex; tarsi with joint 1 elongate,

nearly as long as the others united, 3 strongly bilobed, the claws with a very long curved tooth reaching

outwards nearly as far as the claw itself.

The remarkable insect referred to this genus is closely allied to Orchestes (section

Isochnus, Thoms.), except as regards the structure of the antenne, these being straight,

owing to the extremely short scape, much as in Tachygonus. ‘Ten species of Orchestes

are known from North America, but none have hitherto been certainly recognized

from south of the United States *.

* Rhynchenus crassus and R. rufescens, Fabr., from South America, still remain unidentified.

Testaceous, shining, the eyes, antennal club, scutellum, and meso- and metasternum black or piceous; sparsely

clothed with a fine yellowish pubescence, the upper surface with intermixed long, fine, erect, similarly

coloured hairs, the sides and apex of the elytra, and the under surface, with whitish, pectinate scales,

each elytron with a transverse fascia of closely placed pectinate yellow scales on the disc before the

This genus, which can be placed among the Anthonomina for the present, includes

two

very small, peculiar, closely allied, ‘Tropical-American forms, much resembling a

Miarus or Gymnetron at first sight, but differing from them in the 7-jointed funiculus,

the

unemarginate, very short prosternum, the almost contiguous anterior coxe, &c.

The Brazilian species is taken as the type, the head of the Panama insect having been

lost

while under examination.

(1. Teridates seriatus, sp.n. (Zerambus * seriatus, Tab. XI. figg. 24, 24a, 6.)

Black, shining, the antenne and legs ferruginous ; clothed with a fine grey scattered pubescence, which 1s

transversely arranged on the prothorax and becomes seriate on the elytra, there being a single series

of fine hairs down each stria as well as along the suture, the latter being imbricate with the series on the

opposite elytron, each of the interstices with a row of long, semierect, somewhat closely placed sete; the

vestiture beneath white and squamiform, that of the legs piliform. Head closely punctate ; rostrum closely,

TERIDATES.—THYSANOCNEMIS. 203

rugulosely punctate and pubescent at the base, for the rest sparsely punctured and bare, the antenne

inserted at about three-fifths from the apex. Prothorax narrowing almost from the base, closely punctate,

with indications of an abbreviated smooth median line. Elytra coarsely punctate-striate, the interstices

scarcely wider than the striz, almost flat, and rugulose. Beneath coarsely, shallowly punctate.

Length 13, breadth 1 millim.

Hab. BraztL, Rio Janeiro (coll. Pascoe in Mus. Brit.).

One specimen, probably a female. The pygidium is exposed, but this is due to the

apex of the abdomen being unduly extended. ‘The elytra are widest a little below

the base, their general shape being cordiform. |

2. Teridates confusus, sp. n. (Terambus confusus, Tab. XI. fig. 25.)

Very like 7. sertatus, but with the femora and tibiz black; the prothorax more densely punctured; the elytra

broader anteriorly, with the interstices flat and wider than the strize; the pubescence more abundant,

and confusedly arranged on the elytra, there being two irregular rows of fine hairs between the seriate

interstitial sete, the latter more seattered than in 7. seriatus, the line of pubescence along the suture not

imbricate; pygidium covered by the elytra.

Tychiides vrais, Lacordaire ; Tychiini, Leconte.

Two genera of this group are represented in Central America, S¢ebinea including

some peculiar isolated forms.

THYSANOCNEMIS.

Thysanocnemis, Leconte, Proc. Am. Phil. Soc. xv. p. 214 (1876); Casey, Ann. New York Acad.

Sci. vi. p. 425 (1892).

? Plocetes, Leconte, loc. cit. p. 2138.

Four species of this genus have been described, all from the Southern United States,

and numerous others from our region are here referred to it.

In the type of Thysanocnemis, T. fraxini, Lec., the anterior tibie are thickened and

ciliate in the male, but in the other N.-American forms, as described by Casey, and in

those now added, the anterior tibie are simple in both sexes.

Plocetes, Lec., to judge from the description, seems only to differ in having a short,

carinate rostrum, a peculiarity possessed by the males of certain species of Thysanocnemis.

The various Central-American forms are recognizable by the peculiar maculation and

vestiture of the elytra, which are very much wider than the prothorax, the laterally

angulate second and third ventral sutures, the toothed tarsal claws, the large and

narrowly separated eyes, &ec. The antennal club is ovate and very similar in form in

the species here described. All the tibie are unguiculate, except in 7. brevis and

T. pusillus, which have the hind pair unarmed at the apex.

almost contiguous above, the elytra with two broad, clearly-defined, transverse, black

fasciee separated by a narrow ferruginous band.

4, Thysanocnemis suturalis, sp.n. (Tab. XI. figg. 29, 29 a.)

Subovate, rufo-piceous, darker beneath, the antenne and legs ferruginous, the femora blackish in the middle ;

clothed with fine yellowish-grey pubescence, that on the first elytral interstice velvety-black from a little

below the base to the apex and that on the scutellum whitish, the elytra also with short, scattered,

whitish, squamiform sete, which tend to form a common, transverse, irregular, postmedian fascia (the

black sutural stripe being interrupted in a line with this by a patch of pallid pubescence), and extend

down the second interstice thence to the tip. Head rugulosely punctate, the eyes narrowly separated ;

rostrum stout, curved, about as long as the prothorax, widened in its apical third, carinate down the

middle, the carina widening forwards, sulcate and rugulose at the sides, the antenne inserted towards

the tip. Prothorax transverse, rounded at the sides, a little more narrowed in front than at the base,

densely punctate. Elytra punctate-striate, the interstices convex and densely, rugulosely punctulate.

Intermediate and hind femora obsoletely toothed ; anterior tibiw sinuate.

Length 2,1,-22, breadth 1,,-1} millim. (¢ 2.)

Hab. Guatemaa, Aceituno (Champion).

Two specimens, no doubt male and female, one of them having the rostrum smoother

than the other. Distinguishable by the interrupted velvety-black sutural stripe of the

elytra, this being bordered on each side posteriorly by a row of the pallid squamiform

setee which are scattered over the surface.

5. Thysanocnemis ornatus, sp.n. (Tab. XI. figg. 30, 30a.)

Subovate, rufo-piceous, the elytra with a common, interrupted, angulated, median fascia, widening outwards,

and the apex broadly, the markings connected laterally, black, the antenne and legs ferruginous, the

femora and tibie partly infuscate, the under surface in great part black ; clothed with fine pubescence,

that on the light-coloured portions of the surface yellowish and that on the dark markings black, the

scutellum, the base of the elytra on each side, and an oblong space on the suture a little beyond the

middle, with whitish pubescence, the elytra also with widely scattered, short, whitish, squamiform seta.

Rostrum short and stout, curved, about as long as the prothorax, carinate down the middle, the carina

widening forwards, seriate-punctate at the sides, in the 9 smoother, the antenne inserted towards the

tip; eyes subapproximate. Prothorax transverse, rounded at the sides, narrowed in front, densely

punctate, with indications of an abbreviated, smooth, raised, median line. FElytra punctate-striate, the

interstices feebly convex and densely, rugulosely punctulate. Femora unarmed; anterior tibie sinuate.

Length 2-24, breadth 15-13 millim. (d @.)

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

One pair. Very like 7. suturalis, but with two black fascie on the apical half of

the elytra, these being separated by an angulated line of the ground-colour, on which

at the suture is an oblong patch of whitish pubescence; the squamiform whitish sete

are absent from the apical portion of the second interstice; the eyes are almost

approximate; and the femora are unarmed. From 7. versicolor its smaller size, the

more finely punctured prothorax, and the different arrangement of the elytral markings

sufficiently distinguish it.

6. Thysanocnemis versicolor, sp.n. (Tab. XII. fig. 1, 2.)

Subovate, rufo-piceous, variegated with black, the most conspicuous markings on the elytra being a broad,

angulate, median fascia, which is sometimes interrupted near the suture, and an interrupted, sutural

stripe extending from about the middle to the apex, the under surface in great part black, the antenne

and tarsi ferruginous; clothed with yellowish-grey pubescence, except on the dark markings, where the

vestiture is blackish, the scutellum and a more or less distinct oblong patch on the suture towards

the apex with whitish pubescence, the elytra also with short, scattered, whitish, squamiform sete ; the

vestiture of the under surface whitish. Rostrum (¢) stout, curved, about as long as the prothorax,

seriate-punctate, earinate down the middle and also at the sides, (Q)a little longer and smoother, the

antenne inserted near the apex in the ¢ and at about one-third from the tip in the 2; eyes narrowly

separated. Prothorax transverse, rounded at the sides, narrowed in front, closely, somewhat coarsely

punctate, with a minute interstitial punctuation, and indications of a smooth, raised, median line. Elytra

punctate-striate, the interstices feebly convex, and densely, rugulosely punctulate. Femora unarmed ;

anterior tibize sinuate.

Length 24-3}, breadth 12-1? millim. (¢ 2.)

Hab. Mexico, Cordova (Hége); British Honpuras, Rio Hondo (Blancaneauz) ;

GuaTeMALA, Pantaleon (Champion).

Four specimens, varying a good deal in size and in the extent of the black macula-

tion of the elytra, the median fascia sometimes reaching the suture, but the dark

markings never extending to the tip, as in 7. ornatus. The oblong patch of white

pubescence on the suture towards the apex is conspicuous, the first elytral interstice

being velvety-black before and beyond this. The whitish squamiform sete on the

elytra are coarser and more numerous than in 7. obscurus and T. bicinetus.

7. Thysanocnemis pusillus, sp. n.

Subovate, narrow, ferruginous, the legs testaceous ; somewhat sparsely pubescent, the pubescence of the upper

surface yellowish-grey, slightly intermixed with whitish, that of the under surface white, the usual short

interstitial sete scarcely distinguishable. Rostrum moderately stout, about as long as the prothorax,

seriate-punctate and feebly tricarinate, the antenne inserted towards the tip, the eyes large and very

narrowly separated. Prothorax transverse, moderately rounded at the sides, a little more narrowed in

front than at the base, closely, rather coarsely punctate, with indications of a raised median line. Elytra

subparallel in their basal third, punctate-striate, the strize shallow and the punctures rounded, the inter-

stices almost flat and rugulose. Femora unarmed.

Length 14, breadth 9 millim. (¢.)

Hab. Panama, Tolé (Champion).

One specimen. Distinguishable by its small size and narrow form, the elytra with-

out markings and with the usual sete scarcely distinguishable from the pubescence.

§ 2. Seriate punctures of the elytra oblong.

8. Thysanocnemis zonatus, sp.n. (Tab. XII. figg. 2,2, 2.)

Subovate, rufo-piceous or ferruginous, the elytra with a transverse mark on the disc below the base and two

narrow angulated fascie (one at the middle and the other towards the apex) piceous, the under surface

in great part black, the fifth ventral segment excepted, the antenne and legs rufo-testaceous ; thickly

clothed with yellowish-grey pubeseence, that on the elytral markings sparse and infuscate, the suture

with two blackish spots, the vestiture of the scutellum and under surface whitish, the elytral interstices

each with an interrupted row of short, semierect, pallid setee extending from the base to the apex.

Rostrum curved, moderately stout, about as long as the head and prothorax, closely seriate-punctate,

carinate down the middle and faintly so at the sides, the antenne inserted near the tip; eyes very

narrowly separated. Prothorax transverse, rounded at the sides, narrowed in front, closely, rather

coarsely punctate, with a minute interstitial punctuation and indications of a smooth, raised, median line.

Elytra subparallel towards the base, punctate-striate, the punctures oblong in shape and rather coarse,

the interstices feebly convex and rugulose. Femora unarmed.

Length 21-23, breadth 13-1 millim. (<¢.)

Hab. Guatemaua, Cerro Zunil, Zapote (Champion).

Two specimens. The markings are perhaps wholly due to the colour and

arrangement of the pubescence, which is sufficiently dense to hide the greater

part of the surface; the two fascize on each elytron are connected at the suture by a

blackish spot.

9. Thysanocnemis levirostris, sp.n. (Tab. XII. figg. 3, 3a, 2.)

Subovate, ferruginous, the elytra with a transverse mark on the disc below the base and two narrow,

angulated fasciz (one a little before the middle, extending forward along the suture, and the other

towards the apex) apparently darker, the meso- and metasternum blackish, the rostrum, antenne, and

legs testaceous ; thickly clothed with fine yellowish-grey pubescence, except on the elytral markings,

whieh are almost bare, that on the seutellum and under surface whitish, the suture whitish, with two

dark spots, the elytral interstices each with a row of semierect pallid sets extending from the base to

the apex. Rostrum moderately stout, curved, as long as the head and prothorax, smooth and shining,

shallowly suleate at the sides, the antenne inserted slightly before the middle; eyes very narrowly

separated. Prothorax transverse, rounded at the sides, narrowed in front, closely, rather coarsely

punctate, with a minute interstitial punctuation, the larger punctures absent along a narrow space down

the middle of the disc. Elytra narrowing almost from the base, punctate-striate, the punctures oblong

in shape and rather coarse, the interstices feebly convex and rugulose. Femora unarmed.

Length 22, breadth 13 millim. (9.)

Hab. Panama, Bugaba (Champion).

One specimen. Very similar to the Guatemalan 7. zonatus (the male only of

208 RHYNCHOPHORA.

which is known), but with the rostrum smooth and shining, the elytra a little broader,

narrowing almost from the base, and the sete: longer and more conspicuous; the

brownish spots on the suture (connecting the two fasciee of each elytron) are formed

by patches of darker pubescence, the anterior one extending more forwards than in

T. zonatus. There is a greater sexual difference, too, in the sculpture of the rostrum

than is observable in the male and female of 7. obscwrus and J’. versicolor.

10. Thysanocnemis brevis, sp. n.

Subovate, ferruginous, the meso- and metasternum blackish ; rather sparsely clothed with yellowish-grey

pubescence, that on the sides and middle of the prothorax, the scutellum, the suture in part towards the

apex, and the under surface whitish, the elytra with two angulated fascie of slightly darker hairs, each

interstice with an interrupted row of short, semierect, pallid sete. Rostrum stout, curved, short, about

as long as the prothorax, rugulose at the sides, feebly carinate down the middle, the carina widening out

into a smooth space anteriorly, and also with a fine raised submarginal line, the antenne inserted near

the tip ; eyes very narrowly separated. Prothorax transverse, rounded at the sides, narrowed in front,

closely, somewhat coarsely punctate, with a minute interstitial punctuation and indications of an

abbreviated, raised, median line. Elytra comparatively short, punctate-striate, the punctures coarse,

deep, and oblong in shape, the interstices rather convex and densely rugulose. Femora unarmed.

Length 1%, breadth 1 millim. (¢.)

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

One specimen. Extremely like T. zonatus, but smaller, the rostrum less elongate,

the elytra shorter, with the angulated fascize very faint and formed entirely by a slight

darkening of the pubescence, the latter being sparser. Broader than 7. pusillus, the

seriate punctures on the elytra coarse and oblong.

Sibynes, Schonherr, Gen. Cure. iii. p. 480 (1836) ; Leconte, Proc. Am. Phil. Soc. xv. p. 218.

A genus including numerous Palearctic forms, four only (two from Venezuela, one

from Texas, and one from Lower California) having hitherto been described from

America; the North-American species belonging, however, to Casey’s sections ITI.

and IV. of Zychius would perhaps be better placed in Sibinia, these insects having

the funiculus 6-jointed, as in the species now added from within our limits. The

European Sibinie are said by M. Bedel to attack Caryophyllacee, while the Zychi

are proper to the Papilionacee.

The nine species here described may be grouped thus :—

1. Sibinia rubescens, sp. n.

Oblong-ovate, black, the tip of the rostrum, the antenne (the club excepted), and tarsi ferruginous or obscure

ferruginous ; thickly clothed above with elongate scales, which are mostly of a rusty-red colour, inter-

mixed with white, the squamosity of the scutellum entirely whitish, the scales on the elytra arranged

in a single row on each stria and a double row on each interstice ; the legs and under surface densely

squamose, the scales white intermixed with fulvous. Rostrum about as long as the prothorax, feebly

curved, stout at the base, tapering at the tip, seriate-punctate, bare at the apex. Prothorax transverse,

rounded at the sides, strongly sinuate at the base, narrowed behind as well as in front, constricted before

the apex, closely punctate. Elytra much wider than the prothorax, subparallel towards the base,

separately rounded at the apex; deeply striate, the striz broad and finely punctured, the interstices flat

and rugulose. Pygidium narrowly exposed. Legs short and rather stout.

Length 23, breadth 1} millim.

Hab. Mexico, Durango city (Hoge).

One specimen. Very like Tychius simplex, Casey, from Texas and Arizona, but

larger, the prothorax more rounded at the sides, and the vestiture of the upper surface

in great part rusty-red, the dense squamosity of the under surface not uniformly white.

The funiculus (as in 7’. simplex) being 6-jointed and the elytra separately rounded at

the apex, the species seems best placed in Sibinia.

2. Sibinia rotundata, sp.n. (Tab. XII. figg. 4, 4.)

Broad-ovate, robust, convex, black, the head, the tip of the rostrum, the antenne, and tarsi ferruginous ;

thickly clothed with oblong-oval, imbricate scales, those on the prothorax ochreous and blackish, with a

few white ones intermixed on the disc and at the middle of the base; the vestiture of the elytra in great

part ochreous, with the suture to near the tip and a narrow curved space before the apex black, shading

off into brown, the alternate interstices each with a few scattered white scales, and the suture also

whitish at the tip; the squamosity of the rostrum, legs, and under surface whitish or ochreous, that of

the ventral surface entirely whitish. Rostrum curved, a little longer than the prothorax, stout, tapering

at the tip, seriate-punctate, bare at the apex, the antenne inserted about the middle. Prothorax trans-

verse, rapidly narrowing from the base, which is strongly sinuate, slightly rounded at the sides anteriorly

and constricted in front, densely punctate. Elytra much wider than the prothorax, narrowing from a

little below the base, broadly rounded at the apex, with the sutural angles slightly dehiscent ; finely

punctate-striate, the interstices densely rugulose. Pygidium covered by the elytra. Fifth ventral

segment arcuate-emarginate at the apex. Legs short and stout.

Length 21, breadth 13 millim.

Hab. Panama, Volcan de Chiriqui (Champion).

BIOL. CENTR.-AMER., Coleopt., Vol. LV. Pt. 4, May 1903. 9EE

210 RHYNCHOPHORA.

One specimen, in perfectly fresh condition, no doubt a male. The squamosity of

the elytra is so dense as to hide the sculpture. The sutural angles are very narrowly

separated at the apex, and the pygidium hidden, and the insect therefore would be

almost as well placed in the genus Zychius, but the funiculus is 6-jointed, as in

Sibinia.

3. Sibinia tessellata, sp.n. (Tab. XII. fig. 5.)

Broad-ovate, black, the outer half of the rostrum, the antennew, and tarsi ferruginous; mottled above with a

dense clothing of elongate, ochreous and brown scales, with some whitish ones intermixed, the brown

scales so arranged as to form an irregular series of subquadrate spots on each of the elytral interstices ;

the vestiture of the legs ochreous and that of the under surface whitish. Rostrum longer than the

prothorax, curved, stout at the base and tapering outwards, seriate-punctate, bare, shining, and almost

smooth in its outer half, the antennz inserted about the middle. Prothorax transverse, rounded at the

sides, narrowing from a little before the base and constricted in front, the base sinuate, the surface.

densely punctate. Elytra much wider than the prothorax, narrowing from a short distance below the

base, separately rounded at the apex; finely punctate-striate, the interstices flat and densely rugulose.

Pygidium narrowly exposed. Legs short and stout.

Length 23, breadth 13 millim.

Hab. Mexico, tSierra de Durango * (er Flohr).

One specimen, probably a female. Easily distinguishable by the tessellate arrange-

ment of the brown scales on the elytra. It is less convex than S. rotundata, with the

prothorax more rounded at the sides, the apices of the elytra separately rounded, &c.

4. Sibinia candidata, sp. n.

Broad-ovate, black, the tip of the rostrum, the antenns, and tarsi rufo-piceous or obscure ferruginous ; thickly

clothed with greyish-white, oval scales, the striee with fine, depressed, inconspicuous sete, the vestiture of

the under surface whitish. Rostrum curved, a little longer than the prothorax, stout, tapering at the tip,

rugulose, the scrobes sinuous, the antennx inserted far before the middle. Prothorax transverse, a little

rounded at the sides, narrowing from the base, densely, finely punctate. Elytra wider than the prothorax,

somewhat rounded at the sides, separately rounded at the apex; finely punctate-striate, the interstices

flat and densely rugulose. Legs short and stout.

Length 3-3), breadth 13-1, millim.

Hab. Muxico, Matamoros Izucar, Jalapa (fe).

Two specimens. Easily distinguishable by its broad, robust form and dense,

uniform, greyish-white vestiture.

5. Sibinia picturata, sp.n. (Tab. XII. figg. 6, 6a.)

Subovate, piceous, the outer half of the rostrum, the antenne, and legs (except at the base) ferruginous or

obscure ferruginous ; thickly clothed with elongate-oval, pale ochreous and purplish-brown scales, the

darker scales so arranged as to form two broad vitte on the disc of the prothorax, and an irregular

antemedian fascia and several interrupted lines on the elytra, the interstices of the latter each with

a row of semierect setiform scales, the vestiture of the under surface and legs whitish or ochreous.

*® This insect and various others quoted in the preceding pages were obtained by us from M. Donckier, of

Paris; but there is reason to believe that they were found much further south, probably in Vera Cruz or

Oaxaca, although all are labelled “Sierra de Durango.”

SIBINIA. 211

Rostrum curved, longer than the prothorax, tapering, rugulose, the antenne inserted before the middle.

Prothorax transverse, rounded at the sides, narrowing from a little before the base to the apex, densely,

finely punctate. Elytra much wider than the prothorax, slightly rounded at the sides, separately rounded

at the apex ; finely punctate-striate, the interstices flat and rugulose.

Length 2, breadth 12 millim.

Hab. GuatemaLa, Coban (Conradt).

One specimen, in very fresh condition. Easily recognizable by the broadly bivittate

prothorax and the subfasciate and interruptedly lineate elytra, these markings entirely

formed by the arrangement of the purplish-brown scales, the rest of the westiture of

the upper surface being pale ochreous.

6. Sibinia vagabunda, sp. n.

Subovate, black, the antenne (the club excepted), tibis (except at the base), and tarsi ferruginous, the rostrum

rufo-piceous at the tip; thickly clothed with pale ochreous, imbricate scales, which are elongate in shape

on the head, prothorax, and scutellum, and oval on the elytra, each interstice of the latter with a row of

semierect similarly-coloured setiform scales, the strie also with fine decumbent sete, the vestiture of the

legs and under surface whitish. Rostrum almost as long as the prothorax, tapering towards the tip,

rugulose, the antenne inserted far before the middle. Prothorax broader than long, a little rounded at

the sides, narrowing almost from the base, densely, finely punctate. Elytra much wider than the

prothorax, slightly rounded at the sides, separately rounded at the apex; finely striate, the striz: with

oblong punctures, the interstices flat and rugulose. Legs moderately long.

One specimen.

7. Sibinia fuscipes, sp. n.

Subovate, black, the antenns ferruginous, with the club piceous, the tip of the rostrum and the tibie rufo-

piceous, the tarsi obscure ferruginous; thickly clothed with greyish imbricate scales, which are elongate

in shape on the head and prothorax and oval on the elytra, each interstice of the latter with a row of

semierect pallid sete, the striz also with very fine depressed seta. Rostrum almost as long as the

prothorax, tapering towards the tip, rugulose, the antenne inserted far before the middle. Prothorax

transverse, rounded at the sides, narrowing from a little before the base to the apex, densely, finely

punctate. Elytra much broader than the prothorax, slightly rounded at the sides, separately rounded at

the apex ; finely striate, the striee with oblong punctures, the interstices flat and rugulose. Legs com-

paratively short.

Length 275, breadth 13 millim.

Hab. Guatemata, San Gerénimo in Vera Paz (Champion).

One specimen. Very like S. vagabunda, but with the vestiture greyish, the

prothorax more rounded at the sides, the elytral sete rather finer, the tibize and

tarsi darker.

8. Sibinia aspersa, sp. n.

Subovate, nigro- or rufo-piceous, the tip of the rostrum, the antennee, and legs ferruginous, the femora some-

times a little darker; thickly clothed with rather coarse, greyish-ochreous and whitish, piliform scales,

the middle of the disc, and towards the outer margin; the under surface densely clothed with broad

scales, those on the ventral surface almost entirely white. Rostrum stout, tapering at the tip, rugulose,

bare at the apex. Prothorax transverse, rounded at the sides, narrowing from a little before the base to

the apex, closely punctate. Elytra wider than the prothorax, separately rounded at the apex, the humeri

rounded ; finely punctate-striate, the interstices flat and densely rugulose. Pygidium narrowly exposed.-

Length 2, breadth 1,4, millim.

Hab. Guatemata, San Gerénimo, Purula (Champion) ; Nicaracua, Chontales (Janson).

The description is taken from four fresh specimens from San Gerénimo, the other

three being in less perfect condition. Very like the following species, but a little

broader, and with the coarser white scales scattered over the entire surface of the

elytra (instead of being confined to the suture), the vestiture of the latter less distinctly

arranged in lines, the strie narrower.

9. Sibinia americana, sp. n.

Subovate, black or piceous, the tip of the rostrum, the antenne, tibie, and tarsi, and sometimes the femora

also, ferruginous ; thickly clothed with ochreous or greyish-ochreous piliform scales, the elytra with a

dense line of oval, white, imbricate scales along the suture; the squamosity of the under surface dense

and in great part white. Rostrum stout, tapering at the apex, rugulose, bare at the tip. Prothorax

broader than long, moderately rounded at the sides, narrowing from a little before the base, parallel

behind, densely punctate. LEytra wider than the prothorax, separately rounded at the apex, the humeri

rounded; broadly punctate-striate, the interstices flat and rugulose, each with a treble imbricate series

of piliform scales, the stris with a single row only. Pygidium narrowly exposed. Tibie# hooked at the

inner apical angle in the ¢.

Nicaracua,-Chontales (Belt); Costa Rica, San José (Liolley).

Apparently not uncommon in Central America. The two specimens from Guatemala

city have the vestiture of the upper surface whiter, and the legs entirely ferruginous.

Very like S. melina, Faust, from Venezuela, but narrower, the prothorax less trans-

verse, the suture of the elytra with a line of coarser white scales (of which there is no

trace in 8. melina). The allied S. ochreosa, Casey, from Texas, has the clothing of the

elytra denser and entirely ochreous.

Group PRIONOMERINA.

Prionomérides, Lacordaire,

This group includes some of the most interesting forms of the American Curcu-

lionine.

The section Prionomerides is characterized by the extremely large, triangular,

crenulated, acutely produced tooth on the anterior femora, this being absent in the

Piazorrhinides. Both have a short, broad rostrum, contiguous anterior coxe, ungui-

culate anterior, intermediate, and posterior tibiee, and appendiculate or toothed tarsal

claws. In some of the species of Piazorrhinus the femora are unarmed.

A remarkable genus including a considerable number of Tropical-American species,

and with one representative in the United States. Most of them appear to be very

rarely obtained, and are known only from one or two examples. Some of the forms

have much the facies of various Hispide of the genus Uroplata, on account of the

sides of the elytra being sharply explanate posteriorly. These insects are often

coated in life with a reddish, ochreous, or whitish waxy secretion or efflorescence,

like many of the members of the genera Lixus, Larinus, Sternechus, &c., this being

particularly noticeable in all the specimens of P. mucidus before me. The intermediate

femora are dentate, and the hind pair unarmed.

The Central-American species may be tabulated thus :—

a. Antenne with the funiculus longer than the club; anterior femora black

at the middle; body subovate.

2. Prionomerus simplex, sp.n. (Tab. XII. figg. 8, 8 a.)

Subovate, shining, black; the antenne rufo-testaceous, with the two basal joints of the club black; the legs

rufo-testaceous, the femora at or beyond the middle (the anterior pair very broadly), and the anterior

tibia towards the apex, infuscate or black; clothed with a very fine grey pubescence. Head minutely

punctate; rostrum moderately stout, a little shorter than the prothorax, rugulose at the sides and feebly

carinate in its basal half, for the rest very sparsely punctate; antenne elongate, the club somewhat

loosely articulate and nearly as long as the funiculus ; eyes very large. Prothorax a little broader than

long, subconical, slightly rounded at the sides towards the base ; densely, rugulosely punctate, except in

front, where the surface is almost smooth, the disc faintly carinate in the middle posteriorly. Elytra

fully one-half wider than the prothorax, subparallel in their basal half, the humeri swollen and obtuse,

the apices separately rounded; coarsely punctate-striate, the interstices convex and faintly punctulate.

Legs comparatively slender; anterior tibiee very obliquely truncate at the apex (the inner apical angle

thus appearing acuminate), the inner edge finely serrate to near the middle.

Length 24, breadth 13 millim.

Hab. Panama, Volcan de Chiriqui (Champion).

One specimen, probably a male. Near P. mucidus, but narrower, the anterior

tibiz not so stout and more obliquely truncate at the apex, the prothorax smoother

in front, the elytra not transversely gibbous before the middle, the femora each

annulated with black, the antennal club a little longer.

3, Prionomerus femoralis, sp. n. (Tab. XII. figg. 9, 9a, 6.)

Broad, robust, shining, black, the elytra sometimes with a brassy lustre, the tarsi and antenne rufo-testaceous,

the anterior and intermediate femora broadly rufous at the middle; clothed with a very fine brownish-

grey pubescence, that of the under surface grey. Head almost smooth; rostrum very stout, shorter than

the prothorax, a little shorter in the ¢ than in the 9, somewhat coarsely and closely punctured in its

basal half, much smoother at the tip; antennw short, joints 2-7 of the funiculus closely articulated, 3-7

strongly transverse, the club compact, about as long as the funiculus. Prothorax conical, nearly as long

as broad, constricted towards the apex, and usually more or less distinctly sulcate down the middle

posteriorly, finely, rather sparsely punctate. Elytra broadly subquadrate, almost as broad as long,

trausversely gibbous immediately below the base, the humeri oblique in front and a little swollen, the

PRIONOMERUS. 215

apices broadly and separately rounded; rather coarsely punctate-striate, the interstices feebly convex and

closely, minutely punctate. Legs short.

Length 3-3,,, breadth 23-23 millim. (¢ 2.)

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

Numerous examples. Differs from the following species in the absence of the

median carina on the prothorax. In the British Museum there is an unnamed insect

from Minas Geraes, Brazil, which is very like P. femoralis, but differs from it in having

the prothorax rugosely punctured and less conical in shape,and the intermediate

femora wholly red.

4, Prionomerus carinatus, sp.n. (Tab. XII. fig. 10, prothorax.)

Extremely like P. femoralis, but with the intermediate and posterior femora and tibie often entirely rufescent ;

the prothorax with a sharp median carina extending from the middle to the base; the elytra coarsely

and deeply punctate-striate; the eyes a little more prominent; the rostrum in the d very short, and

sparsely, coarsely punctate.

Length 3;,-33, breadth 23-24 millim. (d @.)

Hab. Mexico, Toxpam (Sallé), Jalapa (Hoge); Guatemaua, Coban (Conradt).

Seven specimens. A northern form of P. femoralis, and certainly requiring a name.

Both are often covered, when fresh, with a reddish or reddish-ochreous efflorescence.

5. Prionomerus rugicollis, sp.n. (Tab. XII. figg. 11, 11 a-c.)

Broad, robust, opaque, deep black, the antenne piceous, with the club reddish at the tip, the tarsi rufo-

testaceous; clothed with a very fine brownish pubescence. Head almost smooth; rostrum short and

stout, shining, sparsely punctate, the punctuation closer at the base; antenne short, joints 2-7 of the

funiculus closely articulated, 3-7 strongly transverse and becoming wider outwards, the club compact and

distinctly longer than the funiculus. Prothorax a little broader than long, conical, constricted before

the apex, the entire surface densely, rugosely punctate. Elytra broadly subquadrate, transversely

gibbous immediately below the base, the humeri oblique in front and a little swollen, the apices separately

rounded; deeply punctate-striate, the interstices moderately convex and closely punctate. Legs short ;

anterior tibie stout, very finely serrate and ciliate on the inner edge to about the middle, abruptly.

truncate at the apex.

Length 24, breadth 13 millim.

Hab. Muxico, Jalapa (Hége).

One specimen. Allied to P. femoralis and P. carinatus, differing in its dull surface,

the rugose prothorax, the black femora, the relatively shorter legs, &c. From

P. bigibbosus, Boh., it is sufficiently distinguished by the absence of the large tubercle

on the disc of each elytron; and from the North-American P. calceatus, Say (carbo-

narius, Gyll.), by its shorter form, more prominent humeri, less rugose elytra, and

shorter legs. In the British Museum there is a mutilated insect from Cayenne

(labelled with the MS. name of P. flavitarsis, Jekel) that is very like P. rugicollis,

but differs from it in having the scape and funiculus of the antenne testaceous.

A species not represented in our collection, and easily recognizable by the very large

tubercle between the third and fourth elytral strie before the middle. The type (with

that of P. mucidus) has been communicated by Dr. Sjéstedt, of the Stockholm Museum,

7. Prionomerus abdominalis. (Tab. XII. figg. 12, 12a.)

Broad, robust, black, the abdomen, the intermediate and hind legs entirely, and the anterior tarsi, testaceous,

the anterior margin of the pronotum and the anterior femora at the apex beneath rafous, the antenne

rufo-testaceous, with the two basal joints of the club infuscate; the upper surface mottled with patches

of white pubescence, which is rather long on the prothorax, the scutellum with white pubescence, the

sutural elevation of the elytra clothed with fulvous heirs, the anterior legs and under surface with

whitish hairs. Head almost smooth; eyes large and prominent; rostrum short and stout, shining,

punctate at the base, smooth at the tip; antenne short, the club longer than the funiculus, with deep

sutures. Prothorax a little broader than long, subconical, constricted before the apex and slightly sinuate

prominent, rounded externally, and subtruncate in front, the apices separately rounded ; deeply punctate-

striate, the interstices rather convex and finely punctate, 1 with a large, flattened, subconical prominence

before the middle, 4 with an oblong prominence below the base, and 5 with one at the middle, and 6 also

conspicuously raised at its point of termination. Legs short.

Length 24-3, breadth 1,%,-2) millim.

Hab. Panama, Volcan de Chiriqui 3000 feet (Champion).—CotomBia (Mus. Brit.) ;

Braziu'.

Two specimens, differing from the others I have seen from South America in their

smaller size and more slender intermediate and hind legs. Easily distinguishable by

its prominent eyes, bituberculate prothorax, quadrate, nodose elytra, and mottled

pubescence. The antennal club is distinctly longer than the funiculus. The elytral

strize 1-3 are strongly sinuous before the middle, being pushed out of position by the

large sutural elevations. Compared with P. flavicornis (Fabr.), Boh., the elytra are

more quadrate in shape and have more numerous elevations on the disc.

8. Prionomerus trigonus, sp. n. (Tab. XII. figg. 13, 13a.)

Subtriangular, robust, opaque, black, the intermediate and hind legs entirely, and the anterior tarsi, testaceous,

the antenne rufo-testaceous, with the two basal joints of the club piceous; the elytra sparscly and

extremely finely pubescent, the punctures of the strie each with a minute silvery hair-like scale, the

rest of the surface and the legs with rather long greyish or white pubescence. Head almost smooth, the

eyes very large and prominent; rostrum curved, very stout, shorter than the prothorax, shining, rugosely

punctured at the base, sparsely punctate thence to the tip, the antenn inserted before the middle; the

latter with the club slightly longer than the funiculus. Prothorax subconical, a little broader than long,

strongly constricted before the apex, closely, finely punctate. Elytra broad, subquadrate, acutely,

triangularly dilated on each side posteriorly, transversely gibbous below the base, the apices broadly

subtruncate, with the sutural angles rounded, the humeri somewhat pointed externally and obliquely

truncate in front; deeply punctate-striate, the interstices flat, alutaceous, and minutely punctulate, the

first with a large, somewhat compressed, conical elevation before the middle, Anterior tibixe very obliquely

Length 3}; breadth at the shoulders of the elytra 2715, at the apex 23 millim. (? 9.)

Hab. Panama, Bugaba (Champion).

One specimen. Easily distinguishable by the acutely dilated postero-lateral margins

of the elytra and the conical prominence near the suture. The elytral pubescence is

extremely fine and short. P. trigonus approaches P. leprieuri, Guér., from Cayenne,

but the general coloration is different, the elytral tubercles are not so prominent, and

the margins are less acutely produced.

excepted), the elytra with the base on each side, the dorsal elevations on the inner side, and the disc

thence to the apex, the abdomen, the meso- and metasternum in part, the antenna, the tip of the rostrum,

the intermediate and hind legs entirely, the anterior tarsi, and the anterior femora and tibic at the base

and apex, rufescent or rufo-testaceous; the elytra with the dorsal prominences and the apical declivity

clothed with rather long ochreous pubescence, for the rest very sparsely and finely pubescent, the prothorax,

legs, and under surface with greyish hairs, the vestiture of the scutellum white. Head smooth, the eyes

very large; rostrum stout, short, not nearly so long as the prothorax, shining, rugosely punctured at the

base, for the rest sparsely punctate, the antenne inserted about the middle, the club of the latter as long

as the funiculus. Prothorax conical, a little broader than long, constricted in front, finely punctate.

Elytra very broad, quadrate, transversely gibbous below the base, obtusely, subtriangularly dilated on

each side posteriorly, the sutural angles rounded, the humeri rounded externally and obliquely truncate

in front; deeply punctate-striate, the interstices flat, alutaceous, and minutely punctulate, the first with

a very large, flattened, conical elevation before the middle. Anterior tibis finely serrate and ciliate on

the inner side to about the middle. Intermediate and hind legs rather stout.

Length 33; breadth at the shoulders of the elytra 22, at the apex 23 millim. (? ¢.)

Hab. Panama, Volcan de Chiriqui (Champion). —SourH America!?, Colombia

(Mus. Brit.).

Broader than P. trigonus, the elytra with the dorsal elevations much larger and

divergent, the postero-lateral dilatation rounded externally, and the pubescence longer

and somewhat abundant on the apical declivity. The hairs on the surface are clogged

with the ochreous efflorescence. ‘The antennal club is slightly infuscate at the base.

The single specimen obtained merely differs from the one in the British Museum in

having the elytra a little more explanate at the sides posteriorly.

P. expansus, Pasc., is also an allied form.

Hab. Mexico, Toxpam (Sal/é).

One example. Differs from the other Central-American forms in having the fifth

elytral interstice produced into a long spine at the apex. The elytra, as in C. expla-

natus, have each a large, oblong, velvety-black patch at the middle of the disc.

2. Camptochirus explanatus, sp.n. (Tab. XII. figg. 16, 16 a.)

followed and preceded by a deep transverse groove. Elytra much wider than the prothorax, oblong-

quadrate, flattened on the disc, the humeri angularly raised and dilated, the apices subtruncate ;

punctate-striate, the interstices broad, flat, densely rugulose, and here and there nodose, the fifth with

Length 551,-6%, breadth 24-3 millim. (¢ 2.)

Hab. Nicaragua, Chontales (Belt, Janson).

Four specimens, no doubt including both sexes, one of them having a longer and

smoother rostrum than the others. The more elevated portions of the surface are

clothed with short bristly hairs. This species is a near ally of the S.-American

C. chiragra (Fabr.), but has more angular humeri to the elytra, and the marginal

dilatation larger.

8. Camptochirus angulatus, sp.n. (Tab. XII. fig. 17.)

prothorax, very sparsely punctate, a little longer and smoother in the 9, the antenne inserted at about

one-third from the base, joints 1 and 2 of the funiculus subequal in length, 3-7 short, transverse, the club

as long as the funiculus. Prothorax slightly broader than long, a little rounded at the sides, narrowed

and constricted in front and narrowed behind, closely, finely punctate, the disc quadrinodose and shallowly

grooved down the middle. lytra considerably wider than the prothorax, elongato-quadrate, the humeri

the Chiriqui and Mexican examples, and obtuse or subrectangular in those from San

Gerénimo and Panajachel respectively. This species differs from C. explanatus in its

narrower shape, the less nodose prothorax, the more coarsely punctured elytral strie, the

convex, shining interstices, the more obtuse humeri, and the unarmed posterior femora ;

and from C. chiragra (Fabr.) in its more elongate shape, the less rounded sides of the

prothorax, and the angular lateral dilatation of the elytra. The varietal form may

prove to be distinct.

4, Camptochirus deplanatus, sp. n. (Tab. XII. fig. 18.)

Elongate, narrow, slightly shining, black, the tip of the rostrum, the front of the prothorax, the shoulders

and the apical margin of the elytra, the antennz (the basal half of the club excepted), the intermediate

and hind legs (the middle of the femora excepted), the anterior tarsi and knees, and the apex of the

anterior tibie, ferruginous or rufo-testaceous ; the surface mottled with grey and brownish pubescence,

the suture of the elytra with an elongate streak of velvety-black hairs at the middle, the vestiture of the

scutellum white. Head, rostrum, and antenne as in C. angulatus. Prothorax broader than long,

narrowed and constricted in front and narrowed behind, closely punctate, the dis¢ feebly quadrinodose.

Elytra wider than the prothorax, elongato-quadrate, flat on the disc, the humeri swollen and subangular,

the apices separately rounded; deeply punctate-striate, the punctures oblong in shape, the interstices

convex, densely rugulose, 4-6 conjointly, subrectangularly lamellato-explanate at their point of termi-

nation. Intermediate femora toothed, the posterior pair unarmed.

Length 3-34, breadth 17-13 millim. (¢ Q.)

Hab. Muxico, Toxpam (Sallé), Jalapa (Hége),.

Two specimens. This is perhaps a feebly developed form of C. angulatus, from

which it differs in its smaller size, the less nodose prothorax, and the more flattened

disc of the elytra. It is very like C. angustus, Pasc., from Colombia, but has the

subapical plate of the elytra rather large and angular (instead of rounded and incon-

spicuous), and the anterior tibie less acutely produced at the inner apical angle.

THEMEROPIS.

Themeropis, Pascoe, Journ. Linn. Soc., Zool. xii. pp. 30, 33 (1874).

The two described species of this genus are from the Amazons and Parana

respectively ; a third is added from Central America.

1. Themeropis binodosa, sp. n. (Tab. XII. figg. 19, 19 a.)

Subconical, robust, dull, piceous, the antenne (the two basal joints of the club excepted), the anterior femora

at the tip, the intermediate and posterior femora at the base and apex, the anterior tarsi in part, the

anterior tibie at the base and apex, and the intermediate and posterior tibiz and tarsi entirely, ferruginous

or testaceous; clothed with fine pubescence, which is of a fulvous colour on the dorsal surface of the

elytra and greyish elsewhere. Head closely punctate, the eyes very large and coarsely facetted ; rostrum

stout, curved, about as long as the prothorax, shining, faintly carinate and rugulosely punctate at the base,

for the rest very sparsely punctured, the antennw inserted at the middle, the club of the latter loosely

articulate and slightly longer than the funiculus, joints 3-7 of which are small and closely articulate.

Prothorax subconical, a little broader than long, feebly constricted in front, closely, rugulosely punctate.

Elytra much wider than the prothorax, widening to near the apex, and separately rounded at the tip,

transversely gibbous at the middle and rapidly sloping thence to the apex, the humeri swollen, sub-

angular, and obliquely truncate in front; deeply punctate-striate, the punctures somewhat distant one

from another, the interstices convex, rugulose, 3 with a large, compressed, erect, subconical prominence at

the middle. Intermediate femora dentate, the posterior pair unarmed. Anterior tibiz strongly bowed,

serrate and ciliate on their inner edge to about the middle.

Length (excl. head) 31, breadth (at the widest part of the elytra) 2 millim.

Hab. British Honpvuras, Rio Hondo (Blancaneauz).

One specimen. Differs from 7. divergens and T. fimbriata in the form or the

position of the elytral prominences (these latter being strongly divergent in both

the South-American species), and also in the unarmed posterior femora.

ECTYRSUS.

Ectyrsus, Pascoe, Journ. Linn. Soc., Zool. xi. p. 177 (1871); xii. p. 33. .

A Tropical-American genus hitherto including three species, EL. villosus, Pasc., from

Rio Janeiro, and EL. pustulatus and FE. albohirtus, Faust, from Venezuela, the two others

now added being closely allied forms. All of them appear to be very rare. Lctyrsus

has much the facies of an Otidocephalus. The intermediate and hind femora are

unarmed ; the tarsal claws are simple and somewhat approximate; the anterior tibiz

are abruptly truncate and unguiculate, or acutely produced, at the apex.

1. Kctyrsus elongatus, sp.n. (Tab. XII. figg. 20, 20a.)

Elongate-ovate, shining, nigro-piceous, the antenne, the anterior tibia and tarsi, and the intermediate and

hind legs, ferruginous or obscure ferruginous; somewhat thickly clothed with very long, erect hairs,

which are mostly whitish in colour, with a few black ones intermixed, the elytra with a dense, oblong

cluster of black hairs on the suture a little before the middle. Head finely punctate; rostrum strongly

curved, a little longer than the prothorax, punctato-sulcate at the sides, for the rest smooth, appearing

carinate in its basal half, the antenne# inserted near the middle, the club of the latter elongate, nearly as

long as the funiculus; eyes very large, contiguous, coarsely facetted. Prothorax slightly broader than

long, feebly constricted in front, rounded at the sides, the latter sinuate towards the base, coarsely, closely

punctate. Elytra oblong, considerably wider than the prothorax, subparallel in their basal half, the

humeri swollen ; coarsely and deeply punctate-striate, the interstices convex, narrow, sparsely punctulate,

and transversely wrinkled. Anterior tibia acuminate at the apex, the intermediate and posterior pairs

_ unguiculate.

Length 34-34, breadth 13-13 millim.

Hab. Gvaremata, San Isidro (Champion); Nicaracua, Chontales (Janson).

‘One specimen from each locality. More elongate than Z. villosus and E. gibbipennis,

and easily distinguishable from both by the dense, oblong cluster of black hairs on the

suture before the middle. In the Guatemalan example of /. elongatus the whitish

hairs show a tendency to form a transverse patch across the suture beyond the middle.

‘The present species also differs from Z. villosus in having the villosity of the upper

surface sparser and shorter, the prothorax more sinuate at the sides behind, and its

punctuation coarser and less close. LE. pustulatus, Faust, is smaller and less elongate,

‘and has the anterior femora ferruginous, and the punctuation of the upper surface not

so coarse.

222 RHYNCHOPHORA.

2. Ectyrsus gibbipennis, sp.n. (Lab. XII. fig. 21.)

Subovate, shining, nigro-piceous, the prothorax reddish in front, the elytra faintly mottled or fasciate with the

same colour, the antenne, the anterior tibie and tarsi, and the intermediate and hind legs, ferruginous

or rufo-testaceous ; somewhat thickly clothed with very long, erect, yellowish-white hairs, which show a

tendency to form a denser cluster on each side of the suture at the middle, the suture itself bordered

with shorter imbricate hairs. Head finely punctate; rostrum strongly curved, a little longer than the

prothorax, punctato-sulcate at the sides and base, for the rest almost smooth, the antennz inserted at

about the middle, the club of the latter ovate, much shorter than the funiculus ; eyes large, prominent,

very narrowly separated. Prothorax a little broader than long, rounded at the sides, narrowed in front

and behind, coarsely, closely punctate. Elytra much wider than the prothorax, comparatively short,

gibbous, subparallel in their basal third, the humeri a little swollen; coarsely and deeply punctate-

striate, the interstices convex, rather broad, sparsely punctulate and transversely wrinkled. Anterior

tibie abruptly truncate at the apex, unguiculate, like the two other pairs.

Length 23-3, breadth 14 millim.

Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion).

Two specimens. This species may be recognized by its comparatively short, gibbous

elytra, the ovate antennal club, and the abruptly truncate apex of the anterior tibie.

E. albohirtus, Faust, is smaller and narrower, and has less convex elytra and fewer hairs.

Broad-ovate, very convex, shining, black, with a brassy or violaceous lustre, the rostrum, antenne, legs, and

abdomen testaceous or rufo-testaceous; thickly clothed with long, adpressed, greyish-white pubescence,

the elytra with a large, common, transverse, rounded space on the disc before the middle almost bare.

Head closely punctate, the eyes very large and somewhat narrowly separated; rostrum very stout,

flattened, much widened outwards, about as long as the prothorax, punctured at the sides, carinate at

the base, the carina flattened, smooth, and widening forwards; antenne short, the club stout and ovate.

Prothorax much broader than long, very wide at the base, rapidly narrowing forwards, closely punctate.

Elytra gibbous, broad, the shoulders not prominent, obliquely truncated in front almost in a line with

the sides of the prothorax (as seen from above); deeply punctate-striate, the interstices convex and

thickly punctulate. Legs rather stout, the intermediate and posterior femora each with an extremely

minute tooth. .

Length 33-32, breadth 23-33 millim. (2.)

Hab. Mexico, Playa Vicente (Sallé), Atoyac (H. H. Smith); Guatemata, Las

Mercedes, Pacific slope (Champion).

A very curious species, with the general facies of a Cionus, and also not unlike

certain American Coccinellids of the genera Poria and Azya, except that it has only

one large bare space on the disc of the elytra. ‘The anterior femora are unarmed, and

the tooth on each of the other pairs is very minute. Three specimens.

®, Piazorrhinus rufipes, sp.n. (Tab. XII. fig. 23.)

Subovate, shining, nigro-piceous, the apical half of the rostrum, the antenna, legs, and pygidium ferruginous,

the femora sometimes blackish at the middle; the head and prothorax clothed with ochreous, and the

sides and apex of the elytra broadly, the propleura, legs, and under surface with white, pubescence,

the scutellum with yellowish hairs, the rest of the elytra almost bare. Head closely, somewhat coarsely

punctate, the eyes very large and well separated ; rostrum very stout, widening outwards, in the ¢ quite

short, in the 9 about as long as the prothorax, coarsely, closely punctate, the apical portion smooth ;

antenne rather long, the club elongate-ovate, acuminate, about equalling joints 2-7 of the funiculus

united. Prothorax transverse, conical, closely, somewhat coarsely punctate, the disc with a smooth,

abbreviated, median carina. Elytra much wider than the prothorax, convex, subparallel at the base, the

humeri a little swollen ; deeply punctate-striate, the interstices narrow, convex, and punctulate. Legs

rather long, the femora unarmed.

Length 23-23, breadth 13 millim. (d¢ 2.)

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

Easily recognizable by the unarmed femora, the comparatively long antenne, and

the peculiar colour and arrangement of the pubescence on the upper surface. The

elytra have a broad space at the sides and apex clothed with rather long, adpressed,

white hairs, and the rest of their surface is almost bare. ‘The pubescence of the

prothorax is golden or fulvous on the disc, becoming white at the sides. Two females

and one male.

3. Piazorrhinus inermis, sp.n. (Tab. XII. figg. 24, 24a.)

Subovate, shining, ferruginous, a little darker beneath, the elytra with a common, V-shaped, blackish patch

at the middle; above somewhat sparsely clothed with ochreous pubescence, the dark elytral marking

bare, the under surface and legs with white hairs. Head closely, somewhat coarsely punctate, the eyes

PIAZORRHINUS. 225

coarsely, closely punctate, smooth at the tip; antenne rather long, the club elongate-ovate, acuminate,

a little shorter than the funiculus. Prothorax transverse, subconical, slightly constricted in front,

coarsely, closely punctate, the disc with a smooth, abbreviated, median carina. Elytra much wider than

the prothorax, convex, subparallel at the base, the humeri a little swollen ; deeply punctate-striate, the

interstices narrow, convex, and punctulate. Femora unarmed.

Length 23, breadth 14 millim. (<¢.)

Hab. Guatemaa, San Gerénimo (Champion).

Very closely allied to P. rufipes, but ferruginous in colour, the elytra with a

common, V-shaped, bare, blackish patch at the middle, the antenne a little longer,

the eyes more convex, the prothorax more coarsely punctured; the vestiture of the

upper surface is yellowish, the elytra having a very large triangular patch at the base,

as well as the sides and apex, pubescent. One specimen.

4, Piazorrhinus uniformis, sp. n.

Subovate, shining, black, the apical half of the rostrum, the antennz, and legs ferruginous ; somewhat sparsely

and uniformly clothed with whitish pubescence, which is seriately arranged on the elytra (there being a

single row of hairs on each of the strive and interstices), the vestiture of the scutellum dense and white.

Head sparsely punctate, rugose between the eyes, which are very large and narrowly separated ; rostrum

very stout, widening outwards, shorter than the prothorax, rugose at the base, smooth at the tip;

antenne short, the club acuminate and about as long as the funiculus. Prothorax much broader than

long, somewhat rounded at the sides, narrowing almost from the base, feebly constricted in front, closely

punctate, the disc obsoletely carinate posteriorly. Elytra much wider than the prothorax, convex,

subparallel in their anterior third, the humeri rounded and not prominent; deeply punctate-striate, the

interstices narrow, convex, and roughly punctulate. Legs short, the femora unarmed.

Length 13, breadth 1 milim. (@.)

Hab. Panama, Tolé (Champion).

One specimen. The uniform, seriately arranged pubescence, the short, ferruginous

legs, and unarmed femora, separate this small species at once from its allies.

5. Piazorrhinus albofasciatus, sp.n. (Tab. XII. figg. 25, 25 a.)

Subovate, rather broad, shining, black, faintly mottled with ferruginous (or obscure ferruginous, with the

prothorax and elytra mottled with black), the antenne ferruginous, the legs wholly or partly of that

colour; the elytra with angulated fascia of ochreous and white hairs, the pubescence on the prothorax in

great part ochreous, and that on the under surface and legs white. Head closely punctate, the eyes

very large and well separated; rostrum very short and stout, slightly longer in the 2, widening

outwards, somewhat coarsely punctate, almost smooth at the tip; antenne short, the club ovate and

compact. Prothorax transverse, subconical, feebly constricted in front, closely punctate, more or less

gibbous and carinate at the middle of the disc. Elytra much wider than the prothorax, convex,

subparallel in their basal half, subtruncate at the apex, the humeri a little swollen; deeply punctate-

striate, the interstices narrow, convex, and punctulate. Legs short and stout, the femora each with an

acute tooth, that on the hind pair small.

on the elytra, the short antenne, stout legs, &c. This is a form of the North-American

P. pictus, Lec., differing from it in having white fascie on the elytra, and the pubes-

cence of the latter sparser and coarser throughout. The colour is variable. Three

specimens.

6. Piazorrhinus rugulosus, sp.n. (Tab. XII. fig. 26.)

Short-ovate, comparatively broad, dull, black, the prothorax (a transverse, anteriorly rounded space on the

disc behind, and a small space before the middle, excepted), the elytra with a narrow space extending

from the humeri downwards, the base of the antenne, the apex of each of the femora, and the tips

of the intermediate and hind tarsi, more or less ferruginous; sparsely clothed with white and ochreous

pubescence, that of the under surface and legs entirely white, the dark patch at the base of the prothorax

bare, the white pubescence on the elytra chiefly confined to the sides and apex, and showing a tendency

to form narrow curved fascie on the disc. Head rather coarsely punctate, the eyes large and well

separated ; rostrum very short and stout, widening outwards, thickly punctured; antenne short, the

club stout, ovate, and as long as the funiculus. Prothorax much broader than long, narrowing almost

from the base, a little rounded at the sides, constricted in front, densely, rugulosely punctate, the dise

with a smooth abbreviated carina behind the middle. Elytra much wider than the prothorax, subparallel

in their basal half, the humeri obliquely truncated in front and not prominent ; deeply punctate-striate,

the interstices almost flat and densely, rugulosely punctate. Legs short and very stout, the femora each

with a rather long acute tooth.

Length 2, breadth 12 millim. (d.)

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

One specimen. The chief characters of this species are the densely rugulose elytral

interstices, the short, very stout legs, with strongly toothed femora, the stout antennal

club, and the peculiar coloration. The pubescence of the prothorax and elytra is most

conspicuous at the sides and apex.

7. Piazorrhinus cyaneus, sp.n. (Tab. XII. fig. 27.)

Ovate, convex, shining, black, the prothorax, elytra, femora, and tibie blue; very sparsely clothed with a

short, fine, grey pubescence. Head sparsely punctate, the eyes large and somewhat widely separated ;

rostrum very stout, widening outwards, shorter than the prothorax, coarsely punctate, obsoletely carinate

at the base; antennee short, the club about as long as the funiculus. Prothorax broader than long,

conical, coarsely, closely punctate, the disc feebly carinate towards the base. LHlytra wider than the

prothorax, somewhat gibbous, the humeri rounded; deeply punctate-striate, the interstices convex and

asperato-punctate. Femora each with a minute tooth.

Length 23-24, breadth 13-1? millim. (2.)

Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion).

Differs from P. cyanescens in its larger size and more robust build, the smaller eyes,

the somewhat gibbous elytra, and the black tarsi. Two specimens.

8. Piazorrhinus cyanescens, sp.n. (Tab. XII. fig. 28.)

Subovate, shining, the upper surface cyaneous or bluish-green, the under surface black, the tarsi and the scape

and funiculus of the antenne ferruginous or rufo-testaceous, the club of the latter piceous; the prothorax,

except on the disc, the scutellum, and a broad, common, U-shaped space on the elytra (extending from

the base to one-fourth from the apex) clothed with greyish-white pubescence, the vestiture of the under

surface and legs white. Head sparsely punctate, the eyes very large and narrowly separated ; rostrum

very short and stout in the g, a little longer in the 9 , widening outwards, carinate and thickly punctate

to about the middle and almost smooth at the tip; antenne short, the club ovate and about as long as

constricted in front, thickly punctate, the disc with a short median carina. Elytra much wider than

the prothorax, subparallel in their basal half, the humeri broadly rounded ; deeply punctate-striate, the

interstices rather convex, transversely rugose, and asperato-punctate. Legs short, the femora each with

a minute tooth.

Var. The prothorax seneons, the elytra cyaneous, the pubescence yellowish and a little more extended, the

tibie in great part ferruginous.

Length 14-21, breadth 1-13 millim. (¢ @.)

Hab. Panama, Bugaba, Volcan de Chiriqui, Caldera (Champion).

Numerous specimens of the form selected as typical, one only of the variety, the

latter from Caldera. Amongst the various similarly coloured species, the present insect

is easily recognizable by the very large eyes, and the U-shaped pubescent space on

the elytra, this extending forwards along the sides of the prothorax.

9. Piazorrhinus metallicus, sp.n. (Tab. XII. fig. 29.)

Subovate, shining, the upper surface blue or bluish-green, the under surface black, the antenne in great part

piceous, the tarsi rufo-testaceous; clothed with a few, widely scattered, short, greyish-white hairs, which

in one specimen form a narrow, sinuous, transverse, median fascia on the elytra, the vestiture of the

scutellum and under surface white. Head, rostrum, antennx, and prothorax as in P. cyanescens. Hlytra

much wider than the prothorax, subparallel in their basal half, the humeri a little swollen ; with shallow,

somewhat coarsely punctured striz, the interstices almost flat, punctulate, and transversely wrinkled.

Femora each with a short, distinct tooth.

Length 2-24, breadth 14 millim. (¢ @.)

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

Three specimens, all somewhat abraded. ‘This is perhaps an extreme form of

P. cyanescens, with the elytra less asperate than usual; the very scanty pubescence

visible on the elytra, however, forms (in one example) a narrow, sinuous, transverse,

median fascia, instead of covering a large U-shaped space. The allied P. splendens,

Faust, from Venezuela, has the upper surface golden-green, and more polished than

in P. metallicus, the pubescence arranged in a longitudinal vitta on the disc of each

elytron, and the legs entirely testaceous.

10. Piazorrhinus asperatus, sp. n.

Subovate, robust, the head and prothorax dull, the elytra slightly shining, black, the tarsi and joints 2-7 of

the funiculus rufo-testaceous, the rest of the antenns piceous ; clothed with a few, widely scattered,

short, greyish-white hairs, which are arranged in an irregular ring on the disc of the elytra below the

scutellum and in a transverse fascia thence to the outer margin. Head closely punctate, rugose between

the eyes, which are moderately large and widely separated ; rostrum very stout, widening outwards,

about twice the length of the eyes, rugosely punctured at the base, much smoother at the tip; antenne

short, the club ovate and as long as joints 2-7 of the funiculus united. Prothorax convex, a little

broader than long, subconical, slightly rounded at the sides, constricted in front, rugosely punctured, the

disc carinate towards the base. Elytra much broader than the prothorax, convex, subparallel in their

basal half, the humeri obliquely truncate in front and rounded externally ; deeply punctate-striate, the

interstices almost flat and asperato-punctate. Legs short, the femora each with a small sharp tooth,

the tarsal claws with a sharp tooth.

Length 23,, breadth 13 millim. (2.)

Hab. Guaremata, Cahabon in Vera Paz (Champion).

One specimen, slightly abraded. Broader and much more robust than P. scutellaris,

the rostrum very broad, the femora acutely toothed, the tarsal claws with a sharp

tooth, the elytral interstices wider and less convex. The elytra, as in that species,

have an angulated transverse fascia before the middle, which is dilated into an

- irregular ring on the disc.

p- 210°.

Subovate, the head and prothorax dull, the elytra shining; black, the elytra with a brassy lustre, the antenne

and tarsi rufo-testaceous, the antennal club sometimes infuscate ; sparsely clothed with grey or yellowish

pubescence, which on the elytra is mainly concentrated into two narrow transverse fascise—the one

before middle strongly angulate and sending off a branch to the scutellum, the other straighter and

placed at about one-third from the apex,—the vestiture of the scutellum, under surface, and legs white.

Head sparsely punctate, the eyes comparatively small and somewhat widely separated ; rostrum stout,

very short, and rugulosely punctate in the g, longer and with the apex nearly smooth in the 9; antenne

short, the club ovate. Prothorax transverse, subconical, closely punctate, sometimes with a short median

carina. Elytra much wider than the prothorax, subparallel in their basal half, the humeri a little

swollen ; deeply punctate-striate, the interstices convex and roughly punctulate. Legs comparatively

slender, the femora each with an excessively minute tooth.

Eizht specimens, differing from North-American examples of P. scutellaris in having

the pubescence a little shorter and the elytral fascie somewhat narrower. Extremely

like P. cingulatus, but with the eyes much smaller, the elytral pubescence differently

arranged, and the legs more slender, the femoral tooth being very minute.

12. Piazorrhinus cingulatus, sp.n. (Tab. XII. fig. 30.)

Subovate, the head and prothorax dull, the elytra shining; black, the elytra with a brassy or violaceous lustre,

the rostrum reddish at the tip, the antennse and tarsi ferruginous or rufo-testaceous, the antennal club

sometimes darker ; sparsely clothed with a grey or yellowish pubescence, which on the elytra is concen-

trated into an irregular patch behind the scutellum and a common, curved fascia (extending outwards to

beneath the humeri) at the middle of the disc, the vestiture of the seutellum, under surface, and legs

white. Head sparsely punctate, the eyes very large and narrowly separated ; rostrum very short and

stout in the d, longer in the 9, widening outwards, thickly punctate, in the 2 feebly carinate at the

base and almost smooth at the tip; antenne short, the club ovate. Prothorax broader than long,

slightly rounded at the sides, subconical, closely punctate, and sometimes with a short median carina,

Elytra much wider than the prothorax, subparailel in their basal half, the humeri broadly rounded ;

deeply punctate-striate, the interstices rather convex and closely asperato-punctate. Legs moderately

stout, the femora each with a small tooth.

Length 13-22, breadth 1-14 millim. (d 2.)

Hab. Guaremata, San Gerénimo, Tamahu, and Senahu in Vera Paz (Champion) ;

Panama, Bugaba, Volcan de Chiriqui (Champion).

Numerous examples. Very like P. scutellaris, but differing from it in the very large

eyes and in the arrangement of the elytral pubescence, the latter forming a single

curved fascia at the middle in P. cingulatus and two transverse fascie in P. scutellaris.

The last-mentioned character also separates P. cingulatus from P. cyanescens, which,

again, is otherwise coloured. The pubescence is usually grey, but is sometimes

yellowish on the prothorax and on the elytra as well.

13. Piazorrhinus albocinctus, sp. n.

Oblong-subovate, shining, black, the apex of the rostrum, the antenne, and tarsi ferruginous, the shoulders

of the elytra reddish; the prothorax (except along the middle of the disc), the humeri, and a curved

oblique fascia extending thence to the suture, clothed with ochreous pubescence ; the elytra with a

common, broad, curved fascia before the apex, and the apex itself narrowly, the scutellum, the head, the

under surface, and legs with white pubescence, the rest of the elytral surface almost bare. Head closely

punctate, the eyes very large, convex, and narrowly separated ; rostrum very short and stout, not longer

than the eyes, thickly punctured ; antennz rather short, the club ovate, about as long as joints 2-7 of

the funiculus united. Prothorax transverse, subconical, closely punctate, carinate on the disc. Elytra

considerably wider than the prothorax, slightly fl attened on the disc anteriorly, subparallel in their basal

half, the humeri not prominent; deeply punctate-striate, the interstices narrow, convex, and roughly

punctulate. Legs rather short, the femora each with a minute tooth.

Length 21, breadth 13 millim. (d .)

Hab. Guaremata, El Tumbador, Pacific slope (Champion).

One specimen. Very like P. rufipes, from Chiriqui, but narrower, with a much

shorter rostrum, more convex eyes, shorter antenne, with a smaller and much less

elongate club, shorter legs, with the femora and tibiae black and the femora toothed,

and the broad, curved, white apical fascia of the elytra divided into two by a transverse

bare space.

14. Piazorrhinus vestitus, sp. n.

Oblong-subovate, shining, black, the tip of the rostrum reddish, the antenne and tarsi rufo-testaceous; thickly

pubescent, the pubescence yellowish on the disc of the prothorax and around the scutellum, and white

elsewhere, the elytra each with a large space at the side, which becomes narrower inwards and reaches

the second stria at about the middle, and a narrow transverse space before the apex, almost bare; the

legs sparsely clothed with white hairs. Head closely punctate, the eyes very large and narrowly

separated; rostrum very short and stout, not longer than the eyes, thickly punctate ; antenne short,

the club stout and ovate. Prothorax broader than long, subconical, closely punctate, the disc carinate.

Short-ovate, dull, the elytra somewhat shining ; black, the elytra with a brassy lustre, the antenne piceous

with the funiculus ferruginous, the tarsi rufo-testaceous ; sparsely clothed with grey pubescence, which

on the elytra is here and there concentrated, and shows a tendency to form an interrupted angulated

fascia before the middle, the vestiture of the scutellum white. Head sparsely punctate, the eyes very

large and narrowly separated; rostrum stout, very short, not longer than the eyes, rugulosely punctate,

smoother and shining at the tip; antenne very short, the club ovate, about as long as joints 2-7 of the

One specimen. Shorter in form than P. cingulatus and its allies, the legs shorter

and stouter, the antenne very short, the elytral pubescence irregularly and more

widely distributed, but showing a tendency to form an angulated fascia before the

middle. Narrower and more ovate than P. rugulosus, the prothorax conical in shape,

the femoral tooth scarcely visible, the coloration and vestiture very different.

+ This genus, the type of which I have seen, is described as being without a scutellum, but this is a

mistake, a minute scutellum being visible. The insect has prominent humeri, a long, exserted head,

evanescent scrobes, a very peculiarly shaped prothorax, and fully developed wings.

A considerable number of species have been already described from Mexico, the types

of all but one of which have been seen by me, but none from the rest of our region.

About seventy are here recognized as distinct, many of which appear to be confined to

particular districts, and it is therefore very difficult to decide as to the true limits of

some of the very closely allied species. In addition to the large amount of material

contained in our collection, I have also examined numerous Central-American

Otidocephali belonging to the Museums of Stockholm, Berlin (including the Mexican

series got together by the late Julius Flohr), Dresden, and London, and various Mexican

species communicated by Herr R. Becker of Berlin.

The North-American O. levicollis and the Mexican O. dugesi have been bred from

the galls of a Cynips on oak, and 0. dichrous has been found in Florida on old leaves

of Chamerops. The numerous forms taken by myself were mostly beaten from the

branches of oak and other deciduous trees. Fifteen or sixteen species have been

described from North America and Mexico respectively, three from Lower California,

and a few from the Antilles and South America.

The following table is based mainly upon the form of vestiture and the shape of the

femoral tooth, which is present in all of them*. ‘The tarsal claws are always more or

less appendiculate :—

Smith), Oaxaca !2 (Sailé), Atoyac in Vera Cruz, Yolos in Oaxaca (Lohr, in Mus.

Berol.).

A peculiar species, recognizable at once by the prothorax not being narrowed

behind, but with the sides straight and forming an almost continuous outline with

those of the elytra. The general coloration is brassy, sometimes with a faint coppery

tinge. The elytra are clothed with decumbent squamiform hairs, the vestiture of the

rest of the body being piliform. The fifth ventral segment in the male is depressed

in the middle behind and emarginate at the apex; in the female it is shallowly sulcate

down the centre. The femoral tooth is small and triangular.

Otidocephalus grandis, Chevr. Ann. Soc. Ent. Fr. 1877, p. 174, t. 4. fig. 7°.

Hab. Mexico (Mus. Brit.), Tecalco! in Puebla, San Andres Tuxtla in Vera Cruz

(Sallé), Atoyac in Vera Cruz (Flohr, in Mus. Berol.).

This is one of the largest species of the genus, and distinguishable by the very deep

lateral sulci of the rostrum, the subcylindrical, almost smooth prothorax, and the

faintly or obsoletely seriate-punctate elytra, set with scattered, coarse, semierect, white,

squamiform hairs, which become more numerous towards the apex. The legs are stout

and comparatively short, the femora each with a moderately large triangular tooth, the

tibie strongly sinuate within. ‘Two specimens are contained in the Sallé collection,

the largest of which measures 12 millim. in length and 43 millim. in breadth (Chevrolat

gives 14 and 6 respectively).

8. Otidocephalus pilicollis, sp.n. (Tab. XIII. figg. 3, 3a.)

Elongate, black, shining; the head, the base and apex of the elytra, the under surface and legs clothed with

white pubescence only; the disc of the prothorax densely clothed with short blackish hairs, these

becoming white at the sides and base, and more scattered towards the apex. Head almost smooth, the

eyes very large, prominent, and rather narrowly separated; rostrum stout, shorter than the prothorax,

punctato-sulcate at the sides and smooth along the middle; antenne with joint 2 of the funiculus nearly

as long as 1, 3-7 short, the club ovate. Prothorax long, a little narrowed in front and behind, depressed

and closely, rugulosely punctate on the disc towards the base, the punctuation becoming more scattered

on the anterior half, the flanks quite smooth and glabrous. Scutellum small, smooth. Elytra moderately

elongate, convex, somewhat flattened on the disc anteriorly, much wider than the prothorax, widening:

to the middle, the humeri obliquely truncated in front; finely seriate-punctate, the punctures becoming

deeply impressed on the disc towards the base, the interstices flat and almost smooth, except towards

the base, where they are rugulose and convex, 1 (sutural) and 3 appearing sharply raised anteriorly..

Fifth ventral segment slightly depressed along the.middle in the ¢. Legs stout; femora each with a

moderately large, acute, triangular tooth; anterior tibie strongly sinuate within.

Length 64, breadth 23 millim. (¢ 9.)

Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion).

Two specimens. A species easily identified by the short, dense, blackish pubescence

on the disc of the prothorax towards the base, the flanks of the latter being smooth

and glabrous, and the deeply impressed series of punctures at the base of the elytra,

the elytra themselves being pubescent at the base and apex only, and without sete.

4, Otidocephalus depressicollis, sp. n.

Elongate, black, shining; the head, the prothorax, and the base and apex of the elytra very sparsely clothed

with fine, white, decumbent pubescence, the legs and under surface more thickly pubescent. Head

sparsely punctate, feebly foveate between the eyes, which are moderately large and somewhat widely

separated ; rostrum stout, nearly as long as the prothorax, punctato-sulcate at the sides, smooth along

the middle; antenne as in O. pilicollis, Prothorax long, narrowed behind, depressed and densely,

rugulosely punctate on the disc towards the base, the punctuation becoming scattered towards the apex,

the flanks smooth and glabrous. Scutellum small, smooth. Elytra as in O. pilicollis, but with the

OTIDOCEPHALUS. 235

seriate punctures becoming very little more impressed towards the base, and the interstices almost flat

on the anterior portion of the disc. Legs as in O. pilicollis.

Length 63-64, breadth 23-28 millim. (9.)

Hab. Panama, Volcan de Chiriqui 2000 to 4000 feet (Champion).

Closely related to O. pilicollis, but with the pubescence on the rugulose portion of

the prothorax sparser and entirely white, the elytral interstices almost flat at the base,

the eyes smaller and less prominent.

5. Otidocephalus cinereus, sp.n. (Tab. XIII. figg. 4, 4a.)

Elongate, black, shining ; thickly clothed with fine grey pubescence, which is short, close, and uniform on the

elytra, the latter without erect sete. Head closely punctate, not or feebly foveate between the eyes,

which are large and widely separated; rostrum stout, much shorter than the prothorax, rugosely

punctato-suleate, with a smooth raised median line; antenne with joints 2-7 of the funiculus short,

2 one-half the length of 1, the club loosely articulated and slightly longer than joints 2-7 united.

Prothorax much longer than broad, subcylindrical, narrowing a little towards the base, closely punctate,

and with indications of a raised median line. Elytra long, much wider than the prothorax, widening to

the middle, where they are somewhat gibbous; closely, finely, and confusedly punctate throughout, the

fine seriate punctures becoming visible towards the suture. Femora each with a small triangular tooth.

Anterior tibie feebly sinuate within.

Length 7-74, breadth 24-3 millim. (3 @.)

Hab, Mexico, Amula in Guerrero 6000 feet (H. H. Smith).

Distinguishable from all the other Central-American forms by the close, uniform,

grey pubescence of the elytra, which are without erect darker sete. Mr. Wickham

has sent us a closely allied species from just beyond our northern boundary*. ‘These

insects approach O. estriatus, Casey, from New Mexico, but the latter has intermixed

blackish sete on the elytra.

6. Otidocephalus mixtus, sp.n. (Tab. XIII. figg. 5, 5 a.)

Elongate, somewhat conical, shining, neous, the antenne (the club excepted) ferruginous ; thickly clothed

above and beneath with long, coarse, decumbent, intermixed, fulvous and white hairs, the elytra without

erect sete. Head closely punctate, the eyes widely separated and not prominent ; rostrum stout, shorter

than the prothorax, rugosely punctato-sulcate ; antennz with joint 2 of the funiculus a little shorter

than 1, 3-7 each shorter than 2, the club ovate. Prothorax long, subcylindrical, closely, finely punctate.

Elytra elongate, much wider than the prothorax, widening to beyond the middle, somewhat gibbous

* Otidocephalus uniformis, sp. n.

Elongate, black, shining, thickly and uniformly clothed with rather coarse grey pubescence, the elytra without

sete. Antenne with joint 2 of the funiculus much longer than 3, and 3-7 subequal in length, the club

ovate and compact. Prothorax narrowed in front and behind, closely punctate, with an interrupted

smooth median line. Elytra very closely and finely punctate throughout, without trace of seriate

impressions towards the suture. Fifth ventral segment feebly emarginate at the apex. Femora each

with a small tooth. Anterior tibie deeply sinuate at the base within, and dilated on the inner side from

the middle to the apex.

segment feebly emarginate at the apex. Legs stout; femora each with a small, triangular tooth;

anterior tibie feebly sinuate within.

Length 74, breadth 3 millim. (<.-)

Hab. Guatemata, San Gerénimo in Vera Paz (Champion).

One specimen. This species somewhat resembles O. pellitus, but the vestiture is

coarser, the sete are absent, the prothorax is finely punctured throughout, and the

elytral interstices are without intermixed coarse punctures. The fulvous and white

hairs are almost equally distributed over the entire surface, the legs included.

7. Otidocephalus pelliceus,

Otidocephalus pelliceus, Rosensk. in Schénh. Gen. Cure. vii. 2, p. 196°.

Hab. Mexico! (Mus. Holm.: 3; Koppe, in Mus. Berol.: 2.)

I have seen two specimens only of this species, including the type, both in very

worn condition. O. pelliceus is not unlike O. pellitus, differing from that species in

its more robust form, the short and stout rostrum in both sexes, and the smoother

elytra, with the pubescence entirely decumbent. The general coloration is nigro-

geneous (not black as described); the prothorax is closely and rather coarsely

punctured, with the flanks smoother; the elytra are finely, confusedly punctate, with

the seriate punctures very little coarser than those of the interstices, the pubescence

whitish, long, rather coarse, and decumbent, without intermixed blackish sete. The

prothorax is subcylindrical in the male, and a little rounded at the sides in the female.

The femoral tooth is small and triangular. The male has the fifth ventral segment

depressed in the middle behind and very feebly emarginate at the apex.

8. Otidocephalus multilineatus, sp. n. (Tab. XIII. figg. 6, 6 a.)

Elongate, black, shining ; clothed with rather long, decumbent, white pubescence, which on the elytra is

concentrated into a comparatively broad line on the interstices 2, 4, 6, and 8, and a narrow one on each

of the others. Head sparsely punctate, shallowly sulcate between the eyes, which are large, prominent,

and somewhat widely separated ; rostrum not very stout, a little shorter than the prothorax, irregularly

punctato-sulcate, smooth along the middle ; antenne with joint 2 of the funiculus about half the length

of 1, 3-7 shorter, the club oblong-ovate. Prothorax moderately long, convex, a little narrowed in front

and behind, thickly punctate, with a smooth median line anteriorly. Elytra three times the length of,

and much wider than, the prothorax, gradually widening to about the middle, the humeri obtuse; finely

punctate-striate, the interstices flat, 1, 3, 5, 7, 9 each with a single, and 2, 4, 6, 8 with an irregular

treble, row of minute punctures. Femora each with a small triangular tooth. Anterior tibie much

curved externally and strongly sinuate within. .

Length 63, breadth 24 millim. (?)

Hab. Mexico, Cuernavaca in Morelos (Hége).

One specimen. ecognizable by its elongate shape, the comparatively short

prothorax, the multi-lineate arrangement of the elytral pubescence, the small femoral

tooth, the curved anterior tibie, and the absence of erect sete on the elytra.

OTIDOCEPHALUS. 237

9, Otidocephalus fiohri, sp. n.

Elongate, black, shining ; somewhat thickly clothed with fine, decumbent, white pubescence only, which on the

elytra is concentrated in a rather broad stripe along each interstice, that on 1, 3, and 5 a little narrower

than the rest. Head somewhat closely punctate, the eyes moderately large and widely separated ;

rostrum short and stout, very much shorter than the prothorax, rather closely punctate, sulcate laterally,

and obsoletely carinate between the eyes anteriorly ; antennal club oblong. Prothorax moderately long,

subcylindrical, a little narrowed behind, closely punctate. Elytra two and one-half times the length of,

and much wider than, the prothorax, gradually widening to about the middle, the humeri obliquely

truncated in front and somewhat swollen; punctate-striate, the interstices almost flat, 1, 38, and 5 each

with about two, and the others with three or four, irregular rows of minute punctures. Femora each with

a small triangular tooth. Anterior tibiw feebly curved externally and strongly sinuate within.

Var.? Rostrum slightly longer; elytra with the pubescence a little coarser, and partly fulvous, the interstices

each with three or four irregular rows of minute punctures.

Length 84-84, breadth 3-37 millim.

Hab. Mexico, Santiago Ixcuintla, Tepic (Lohr, in Mus. Berol.).

One specimen from each locality, the individual from Tepic belonging to the

varietal form, apparently male and female of the same species. Broader than

O. multilineatus, the prothorax relatively longer, subcylindrical, and more closely

punctured, the rostrum stouter, the lines of the pubescence on the elytra wider, and

the anterior tibiz less curved.

10. Otidocephalus tzeniatus, sp. n.

Elongate, narrow, black, shining ; sparsely clothed with decumbent white hairs only, which on the elytra are

rather coarse and serially arranged—a double row on each of the alternate interstices 1, 3, 5, 7, 9, and a

single row on the others, the latter becoming obsolete from about the middle forwards. Head sparsely,

rather coarsely punctate, not or shallowly foveate between the eyes, which are moderately large and

widely separated ; rostrum curved, about as long as the prothorax in the ?, shorter in the ¢, punctato-

sulcate, smooth and subcarinate along the middle; antenne long, joint 2 of the funiculus much shorter

than 1, 3-7 shorter than 2, the club oblong-ovate. Prothorax narrow, subcylindrical, moderately long,

a little narrowed in front and behind, very sparsely punctate. Elytra elongate, convex, flattened on the

disc at the base, much wider than the prothorax, widening to the middle, the humeri obliquely truncate

in front and somewhat prominent ; seriate-punctate, striate towards the suture, the interstices flat, 1, 3,

5, 7, 9 irregularly, minutely, biseriate-punctate, the others uniseriate-punctate from about the middle to

the apex. Legs long and comparatively slender; femora each with a small triangular tooth ; anterior

tibiee sinuate within.

Length 54-63, breadth 2-24 millim. (d 9.)

Hab. Mexico, Juquila in Oaxaca (Sallé), Atlapango, Valley of Mexico (Mohr, in

Mus. Berol.). ;

Three specimens. A rather narrow, elongate form, with double lines of somewhat

closely placed white hairs on the elytra, those on the interstices 2, 4, and 6 not

reaching the base and reduced to a single row, the rostrum about as long as the

prothorax in the female, the legs comparatively long and slender, the femoral tooth

small. 0. teniatus approaches O. albolineatus, but is much more elongate, and has

more slender legs, &c. The absence of the black sete on the elytra separates it from

OQ. lineipennis.

258 ‘RHYNCHOPHORA.

11. Otidocephalus albolineatus, sp.n. (Tab. XIII. figg. 7, 7 a.)

Moderately elongate, black, shining; clothed with decumbent white hairs only, which on the elytra are

arranged in a double or treble row on each interstice, except on 2, 4, and 6, these having a single

incomplete row running from about the middle to the apex. Head rather coarsely punctate, sulcate

between the eyes, which are large and somewhat widely separated; rostrum very stout, much shorter

than the prothorax, rugosely punctate, smooth along the middle. Prothorax moderately long, sub-

cylindrical, much narrowed behind, somewhat coarsely punctate, except down the middle and on two

oblong spaces on each side, which are quite smooth. Elytra wider than the prothorax, widening to

about the middle, subtruncate at the base, the humeri obtuse ; somewhat coarsely punctate-striate, the

interstices almost flat, 2, 4, and 6 from about the middle to the apex uniseriately, and the others from

the base to the apex bi- or triseriately, punctate. Legs rather short; femora each with a small, narrow

tooth ; anterior tibize sinuate within ; tarsal claws feebly appendiculate.

Length 43-52, breadth 2-23 millim. (<.)

Hab. Mexico, Ventanas in Durango (Hége), Valley of Mexico (Flohr, in Mus. Berol.).

Two specimens. The chief characters of this species are the lineate arrangement

of the pubescence on the elytra, the interstices 2, 4, and 6 becoming glabrous and

impunctate towards the base, the peculiar sculpture of the prothorax (the smooth

spaces being separated by a rather coarse, close punctuation), the small femoral tooth,

and the complete absence of erect sete, the whole of the vestiture being white and

decumbent. It has much less elongate elytra than O. multilineatus.

12. Otidocephalus canescens, sp. n.

Moderately elongate, black, shining; clothed with semierect, long, white hairs only, which on the elytra are

somewhat closely placed and arranged in a single or double row on each interstice. Head smooth,

deeply foveate between the eyes, and slightly constricted behind them, the eyes large, prominent, and

rather widely separated ; rostrum stout, very much shorter than the prothorax, sulcate and rugosely

punctate at the sides, smooth along the middle. Prothorax subcylindrical, moderately elongate,

narrowed behind, very sparsely, irregularly punctate. Elytra convex, much wider than the prothorax,

widening to the middle, subtruncate at the base; punctate-striate, the interstices flat at the sides, feebly

convex on the disc, minutely bi- or uniseriate-punctate from the base to the apex. JFemora each with a

large triangular tooth. Anterior tibia strongly sinuate within.

"Length 5-52, breadth 2-21 millim. .

Hab. Mexico, Acapulco (Hége; Flohr, in Mus. Berol.), Tlaltizapan (Flohr, in Mus.

Berol.). :

Three specimens. This species resembles 0. albolineatus in general facies, differing

from it, however, in the much longer and more erect pubescence, the smooth, deeply

foveate head, the very sparsely punctured prothorax, the uniformly seriate-punctate

elytral interstices, and the large femoral tooth. The complete absence of the blackish

sete on the elytra separates it at once from 0. foveifrons.

13. Otidocephalus vestitus, sp.n. (Tab. XIIL. figs. 8, 8a, b, 3.)

Otidocephalus vestitus, Jekel, in litt.

Moderately elongate, robust, black, the elytra with a faint brassy lustre; densely clothed with intermixed

brown and white, adpressed, radiato-pectinate scales, the head, prothorax, and elytra also with an

OTIDOCEPHALUS, 239

abundant, short, blackish, suberect setosity and scattered, decumbent, whitish hairs, these latter

extending over the under surface and legs, the vestiture of the metasternal side-pieces very dense and

white. Head densely punctate, the eyes moderately large and widely separated; rostrum short and

stout, depressed at the base above, rugosely punctured and laterally sulcate; antennal club ovate.

Prothorax convex, moderately long, narrowing from the middle forwards and also narrowed behind,

coarsely, deeply, confluently punctate. Scutellum large. Elytra much broader than, and about two and

one-half times the length of, the prothorax, broadly flattened along the inner portion of the disc, sub-

parallel in their basal half, conjointly emarginate at the base, the humeri prominent, but obtuse; closely,

confusedly punctate, the usual seriate coarser punctures barely traceable, the pectinate scales arranged

somewhat in lines, which are here and there separated by small bare spaces. Fifth ventral segment

feebly emarginate at the apex. Legs stout; femora each with a very small triangular tooth; anterior

tibie strongly sinuate within.

Length 8, breadth 34 millim. (¢.)

Hab. Mexico (Mus. Brit.).

This insect agrees with QO. vittatus, Horn (= Cycotida lineata, Pasc.), O. nivosus,

Casey, O. wlkei, Horn, and 0. insignis, Casey, in being thickly clothed with radiato-

pectinate scales * (fig. 84), and is nearest allied to the two latter (the others having

vittate elytra), but differs in various details. The species mentioned are all from the

Southern United States or Lower California, and OQ. vestitus is therefore probably an

inhabitant of the northern part of Mexico.

14. Otidocephalus dugesi, sp.n. (Tab. XIII. figg. 9, 9 a.)

Elongate-ovate, robust, shining, nigro-eneous; thickly clothed with rather coarse, decumbent, grey or

brownish-grey pubescence, which is absent from the five longitudinal series of rounded, sharply defined,

bare spaces on each elytron, the scattered erect blackish sete arising from these portions of the surface.

Head closely punctate, feebly sulcate between the eyes, which are large, somewhat widely separated, and

not prominent; rostrum stout, slightly shorter than the prothorax, rugosely punctato-sulcate ; antenne

with joints 2-7 of the funiculus decreasing in length, the club ovate. Prothorax subcylindrical, longer

than broad, a little narrowed in front and behind, closely, irregularly punctate, with a more or less

distinct, smooth, raised, median line. Elytra oblong, convex, much wider than the prothorax, the humeri

rather prominent ; closely, finely, confusedly punctate, except upon the five series of smooth bare spaces,

each of these with a single setigerous puncture. Legs moderately stout; femora each with a small

triangular tooth ; anterior tibiae feebly sinuate within.

Length 74, breadth 33 millim. ( 2.)

Hab. Muxico, Guanajuato (A. Dugeés).

Two specimens, sent us by Dr. A. Dugés in 1897, with the accompanying note :—

“ Taken (with others) out of a large gall on a branch of an oak in the mountains, in

company with some Cynipides of the genus Synergus, both probably inquilines.”

The species may be readily identified by the five longitudinal series of rounded smooth

spaces on each elytron, which are for the rest thickly pubescent and closely, con-

fusedly punctate.

15. Otidocephalus interruptus, sp.n. (Tab. XIII. figg. 10, 10a.)

Elongate-ovate, robust, shining, piceous or rufo-piceous ; thickly clothed with long, rather coarse, brownish-

grey, decumbent pubescence, which is absent from numerous small bare spaces on the elytra, the

numerous on the elytra. There are three specimens of O. pellitus in the Sallé

collection and one in the Berlin Museum. ‘The varietal form, from Oaxaca, may prove to

belong to a different species. ‘The fulvous hairs predominate on the elytra in all of them.

Hab. Muxico, Chilpancingo in Guerrero (Hoge, H. H. Smith).

A species very like O. linetpennis, but with only four complete lines of white

pubescence on each elytron, and these placed on different interstices, the setz arising

from the intervening spaces, which are uniseriate-punctate. Three specimens.

Hab. Mzxtco, 'Tapachula in Chiapas (Hége).

Two specimens. The four narrow lines of white pubescence on each elytron, the

single series of long blackish sete on each interstice, and the abruptly incurved apex

of the anterior tibiz will serve to distinguish this species, which is nearly related to

O. lineipennis and O. octolineatus.

OTIDOCEPHALUS. 243

22. Otidocephalus brevicollis, sp. n.

Moderately elongate, black, shining ; clothed with short, decumbent, rather coarse, white, squamiform hairs

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

One specimen. The comparatively short prothorax, the wide elytra, with somewhat

abundant, coarse, white, squamiform pubescence and long, erect, black sete, the very

large femoral tooth, &c., will serve to distinguish this species. In general facies it

resembles 0. canescens, O. albolineatus, O. foveifrons, &c.

23. Otidocephalus villosus, sp. n.

Elongate, shining, black, the antenne (the club excepted) ferruginous; clothed with an abundant, intermixed,

Two specimens. Very like 0. hystricosus, but with the femoral tooth much larger,

the anterior tibie dilated beyond the middle, the prothorax closely and coarsely

punctured (except along the median line), the white hairs on the upper surface finer.

The shorter second joint of the funiculus, the more abundant setosity, and the less

closely punctured elytral interstices distinguish it from O. duplicatus. The description

is made from the example from the Flohr collection, the other having less coarsely

seriate-punctate elytra, with the interstices flat, and also differing in some minor details.

One specimen, somewhat abraded. In this insect the elytra have a short, stiff,

rather abundant, blackish setosity, intermixed with coarse, flattened, squamiform, and

narrow white hairs. The interstitial punctuation is irregular and nearly as coarse as

that of the strie. The elytra themselves are more flattened towards the base than in

O. villosus and other allied forms.

One specimen. Smaller and narrower than 0. ericius, the white hairs on the elytra

less erect, finer, and arranged in a double (instead of a single) row on most of the

interstices. ‘Che less prominent humeri, the finer interstitial punctuation, the absence

of the rather broad white scales on the elytra, and the smaller femoral tooth separate

it from O. brevisetis.

This small species may be recognized by the inflated, comparatively short, broad

elytra, which are obsoletely or finely seriate-punctate, and clothed with long, erect,

scattered, rather coarse, white hairs, intermixed with long blackish sete on the disc,

the hairs becoming much more numerous on the apical declivity; the almost smooth

supra-ocular portion of the head; the basally depressed rostrum; and the large, acute,

triangular, femoral tooth.

The specimens from Motzorongo, in Mr. Becker's collection, agree with the type,

now before me, and three others in the Sallé collection and one in the Berlin Museum

probably belong to it, but they have the elytra very distinctly seriate-punctate. The

femoral tooth is larger than in O. senew, and the prothorax and elytra are smoother

elongate, the head is coarsely punctured and without the deep frontal fovea, and the

white hairs on the elytra are coarser and more rigid.

34. Otidocephalus longicollis, sp. n.

Elongate, somewhat conical, black, shining ; the head and prothorax clothed with very fine, scattered, blackish

and white hairs, the elytra with a row of semiecrect, stiff, white hairs along each interstice, intermixed on

the dorsum with fine, erect, blackish sete, the vestiture of the scutellum, legs, and under surface white,

and that of the pygidium brown. Head sparsely punctate, faintly foveate between the eyes, which are

moderately large and widely separated ; rostrum stout, very much shorter than the prothorax, punctato-

suleate at the sides, smooth along the middle; joint 2 of the funiculus slightly longer than 3. Prothorax

long, subcylindrical, a little narrowed in front and behind, sparsely, rather coarsely punctate, more or

less transversely rugose on the disc, a large space at the sides impunctate. LElytra elongate, convex,

flattened on the disc anteriorly, much wider than the prothorax, widening to slightly beyond the middle,

the humeri obliquely truncated in front; finely seriate-punctate, the interstices each with a row of minute

scattered punctures. Femora each with a small triangular tooth. Anterior tibie strongly sinuate

within.

Two specimens, probably males. ‘ More elongate than O. ericius, of the western

coast, the prothorax transversely rugose on the disc posteriorly, the elytra more finely

seriate-punctate, with the white hairs less squamiform and not so numerous. The

‘ntermixed stiff white hairs throughout the entire length of the elytra, which are also

more convex, the less elongate antennal club, &c., separate it from O. apioniformis.

35. Otidocephalus rugicollis, sp.n. (Tab. XIII. figg. 19, 194.)

Very elongate, somewhat conical, eneo-piceous, shining; clothed with widely scattered decumbent whitish

Hab. Muxico, Sierra de Durango? [2] (ex coll. Flohr); Costa Rica [6] (Van

Patten ; Wagner, in Mus. Berol.). |

Two males and one female. In this species the femoral tooth reaches the maximum

development. The elongate elytra separates O. lonyipennis from most of its allies

with a large femoral tooth, the general shape being like that of O. apioniformis.

38. Otidocephalus tonsilis, sp. n.

Elongate, narrow, subconical, black, shining ; clothed with scattered, long, erect, blackish sete, which on the

elytra are arranged in a single series along each interstice, the base of the prothorax with a few long

Length 53-6, breadth 2 millim. (d 2.)

Hab. Guatemata (Sallé, in Mus. Dresden), Capetillo (Champion).

Very like 0. prolongatus, but with the prothorax less cylindrical and smoother, the

‘second joint of the funiculus shorter, the elytral interstices each with a row of sete,

the anterior tibis more curved in the male. The male has the head, rostrum, and

prothorax more coarsely punctured than in the female, and the fifth ventral segment

unemarginate at the tip. Three specimens.

39. Otidocephalus dentipes, sp. n.

Moderately elongate, robust, black, shining; clothed with widely scattered, long, erect, blackish sete, which

on the elytra are arranged in a single series along each of the alternate dorsal interstices, the base of the

prothorax, the scutellum, legs, and under surface with white hairs, the legs with a few blackish ones

Length 63-8, breadth 24-34 millim. (¢ @.)

Hab. Guaremata, Sabo and Sinanja in Vera Paz (Champion); Panama, Caldera in

Chiriqui (Champion).

Broader and more convex than 0. constrictus, the legs more elongate; and also a

close ally of the Mexican O. pubescens, from which it may be separated by the broader

femoral tooth and the absence of long, intermixed, white hairs on the elytra. From

O. inquisitus, Kirsch, from Bogota (the type of which I have seen *), which is of the

same general shape as O. dentipes, it is sufficiently distinguished by the much larger

femoral tooth, the punctured head, the much finer and shallower seriate punctuation

of the elytra, &c. Three specimens from Guatemala, and one from Panama, the latter

treated as a varietal form, but probably distinct.

40. Otidocephalus latidens, sp. n.

Moderately elongate, shining, black, the antenne (the club excepted) reddish ; clothed with scattered blackish

sete: intermixed with a few white hairs, the elytra with the sete long, erect, and arranged in a single

series down each interstice and the white hairs rather coarse, the vestiture of the scutellum and under

surface white, the legs with intermixed white and blackish hairs. Head sparsely punctate, shallowly

foveate between the eyes, which are moderately large and widely separated; rostrum shorter than the

prothorax, punctato-suleate at the sides, smooth along the middle ; antenne with joint 2 of the funiculus

slightly longer than 3, the club oblong-ovate. Prothorax long, subcylindrical in front, narrowed and

distinctly constricted behind, the surface with a few widely scattered punctures, Elytra oblong, much

wider than the prothorax, gradually widening to the middle, moderately convex, the humeri obliquely

truncated in front; finely seriate-punctate, the interstices each with a series of widely scattered fine

punctures. Femora each with an exceedingly large, broad, triangular tooth. Anterior tibie strongly

sinuate within.

Length 54-61, breadth 2-23 millim.

Hab. Mexico, Juquila in Oaxaca (Sallé).

Two specimens. Differs from O. meaicanus in the exceedingly large femoral tooth,

from O. dentipes in the narrower and less inflated elytra and the posteriorly constricted

prothorax, and from 0. tonsilis in its less elongate, broader shape, as well as in having

a few coarse, semierect, white hairs scattered amongst the elytral sete. The inter-

mixed white hairs are coarser than in O. pubescens, and the femoral tooth is broader

and larger.

41. Otidocephalus constrictus, sp. n.

Elongate, black, shining; clothed with widely scattered, long, erect, blackish setez, which on the elytra are

arranged in a single series along each of the dorsal interstices and at the apex are intermixed with

numerous long white hairs, the vestiture of the scutellum and under surface white, the legs with inter-

separated ; rostrum not very stout, curved, nearly as long as the prothorax, depressed at the base above,

punctato-suleate at the sides, smooth along the middle; antennx with joint 2 of the funiculus nearly as

long as 1, 3-7 shorter, the club ovate. Prothorax long, globose in front, constricted and much narrowed

behind, very sparsely, finely punctate, the flanks almost smooth. Elytra moderately long, much wider

than the prothorax, very convex, flattened on the disc anteriorly, rapidly widening to the middle, the

humeri obliquely truncated in front; very finely seriate-punctate, the interstices each with a row of

scattered minute punctures. Femora each with a large, acute, triangular tooth. Anterior tibiw strongly

sinuate within.

Length 54-6, breadth 2-23 millim. (2.)

Hab. Nicaracua, Chontales (Belt); Panama, Bugaba (Champion).

Four specimens. The anteriorly globose, posteriorly constricted prothorax, the

more acute femoral tooth, and the conspicuous intermixed long white pubescence at

the apex of the elytra distinguish O. constrictus from O. dentipes, to which it is other-

wise very closely allied. The non-foveate front, the larger femoral tooth, &c., separate

it from O. pubescens; and the anteriorly globose prothorax from 0. latidens.

Hab. Mexico!~4 (Mus. Holm.; Mus. Brit.), Playa Vicente, Toxpam, Orizaba, Vera

Cruz (Sallé), Jalapa (Hoge), Sierra de Zongolica (coll. Becker), Tomotla (Flohr, in

Mus. Berol.).

We have numerous specimens of this species, varying greatly in size, all from the

State of Vera Cruz. It differs from O. mexicanus and others in having a larger femoral

tooth, the prothorax narrowed and constricted behind, and the elytra with long white

hairs intermixed with the blackish sete, at least towards the apex. The front is foveate.

In some of the smaller examples the seriate punctuation of the elytra is finer, and

becomes almost obsolete laterally. The males have a rather short rostrum, and the

fifth ventral segment unemarginate at the tip. The females are often very much larger

and broader, and have the rostrum almost or quite as long as the prothorax. The types

of O. pubescens and O. albopilosus have been communicated by Dr. Sjéstedt, and they

certainly belong to one species, the two sexes being represented in our series from both

Jalapa and Toxpam. In the single specimen from Zongolica, a male, the eyes are

larger and more prominent than usual, and in one female from Toxpam the dark sete

on the disc of the elytra are in great part replaced by long white hairs.

43. Otidocephalus castaneus, sp. n.

Elongate, shining, castaneous, the antenne ferruginous; the upper surface and legs clothed with a somewhat

abundant, very long, erect, fine blackish setosity and intermixed long white hairs, the vestiture of the

scutellum and under surface white. Head closely, rather coarsely punctate, the eyes moderately large

and widely separated; rostrum almost straight, not very stout, a little shorter than the prothorax,

punctato-sulcate, smooth along the middle; antenne with joints 2-7 of the funiculus subequal in length,

1 twice as long as 2,the club ovate. Prothorax long, much narrowed behind, subcylindrical in its anterior

half, coarsely and somewhat closely punctate, a narrow space along the middle impunctate. Elytra

moderately long, convex, much wider than the prothorax, widening very gradually to the middle,

subtruncate at the base, the humeri rounded ; coarsely punctate-striate, the interstices feebly convex,

and each irregularly bi- or uniseriate-punctate. Legs stout ; femora each with a large triangular tooth ;

anterior tibie strongly sinuate within ; tarsal claws feebly appendiculate.

Length 54, breadth 2 millim. ( *)

Hab. Mexico, Ventanas in Durango (//é¢e).

One specimen. The castaneous coloration, the coarse punctuation, the intermixed

blackish setosity and long white hairs (the blackish sete extending on to the legs),

and the almost straight rostrum, are the principal characteristics of this species.

44, Otidocephalus panamensis, sp. n.

Elongate, black, shining ; clothed with scattered, long, erect or suberect, bristle-like, white hairs, which on

the elytra are sometimes intermixed with a few blackish sete, and arranged in a single series on each

interstice, becoming more numerous towards the apex, those on 2,4, 6, and 8 mostly confined to the

apical declivity, the vestiture of the scutellum, legs, and under surface closer. Head with a few scattered

fine punctures, shortly sulcate between the eyes above, the latter large, prominent, and somewhat narrowly

separated; rostrum very stout, barely two-thirds the length of the prothorax, punctato-sulcate at the

~ sides, smooth along the middle; antenn® with joints 2-7 of the funiculus short, the club ovate. Prothorax

long, more or less globose in front, and narrowed and constricted behind, the surface with a few fine

scattered punctures. Elytra moderately long, convex, much wider than the prothorax, widening to the

middle, the humeri obliquely truncated in front; finely seriate-punctate, the punctures closely placed,

the interstices flat, minutely uniseriate-punctate, 2, 4, 6, and 8 impunctate to about the middle. Fifth

ventral segment feebly emarginate in the centre at the apex in the $. Femora each with a large, acute,

triangular tooth. Anterior tibie strongly sinuate within.

Length 4-6, breadth 13-23 millim. (d 9.)

Hab. Panama, Bugaba (Champion).

More elongate than O. megalops, the frontal fovea small and narrow, the seriate

punctures of the elytra more closely placed and a little coarser, and those on the

alternate interstices not reaching the base, the eyes less prominent in the male,

the femoral tooth large. Found in abundance at Bugaba, the specimens varying

in the intensity of the elytral punctuation and in the colour of the elytral sete.

45. Otidocephalus longipilis, sp. n.

Moderately elongate, shining, black, the antenne and tarsi piceous or obscure ferruginous ; clothed with long,

fine, erect, rigid hairs or sete, which on the elytra are arranged in a single series throughout the length

of each interstice, and are mostly blackish or brown on the disc and white towards the sides and apex,

the vestiture of the scutellum and under surface white, the legs with intermixed white and brown hairs.

Head very sparsely punctate, the eyes moderately large and somewhat narrowly separated ; rostrum

shorter than the prothorax, punctato-sulcate at the sides, smooth along the middle. Prothorax long,

Found in numbers in the valley of the Polochic. This insect is less elongate than

O. panamensis, the elytral setee—which are usually blackish on the disc and white at

the sides and apex—are a little finer and extend along the whole length of each

interstice, and the femoral tooth is larger. The absence of the deep frontal fovea, the

more globose anterior portion of the prothorax, the much smaller average size, &c.,

separate it from O. pubescens; the larger femoral tooth, and the punctured head

without deep frontal fovea, from 0. similis; and the less inflated elytra and their

finer setosity from O. canus. The tarsi are ferruginous in some of the Guatemalan

specimens. :

in a single row along each interstice, the base of the prothorax with a few fine white hairs, the vestiture

of the scutellum and under surface white, the legs with intermixed white and blackish hairs. Head

sparsely punctate, obsoletely foveate between the eyes, which are moderately large, not prominent, and

widely separated ; rostrum stout, much shorter than the prothorax, punctato-sulcate at the sides, smooth

along the middle; antenne with joint 2 of the funiculus very little longer than 3, the club oblong-ovate.

Prothorax long, subcylindrical, slightly narrowed behind, sparsely punctate, a space on the flanks impunc-

tate. Elytra moderately long, much wider than the prothorax, compressed at the sides, somewhat gibbous

posteriorly, gradually widening to the middle, subtruncate at the base, the humeri rounded externally ;

finely seriate-punctate, the interstices cach with a row of fine scattered punctures. Fifth ventral segment

emarginate at the apex. Femora each with a small triangular tooth. Anterior tibiee feebly sinuate within.

Length 52-64, breadth 2;4,-23 millim. (<.)

Hab. Nicaragua, Chontales (Belt).

Two specimens. This insect agrees in many respects with the male of 0. apioniformis,

but has both the rostrum and elytra much shorter, and the fifth ventral segment unim-

pressed along the middle. The elytra are less widened at the base and more convex

than in O. oculatus, and the humeri are a little more prominent and less obliquely

truncated than in O. mexicanus and O. similis.

Hab. Mexico (Mus. Brit.), between Oaxaca and Acapulco! (Mus. Holm.), Capulalpam

(Sallé), Zempoaltepec (Flohr, in Mus. Berol.).

We have two males and two females of this species, agreeing with the type (¢ )

belonging to the Stockholm Museum, and there are two others in the Flohr collection

in the Berlin Museum. It is very like 0. apioniformis, but the rostrum is much

shorter, the eyes are less depressed, and the elytra are relatively broader and more

truncate at the base, with the humeri prominent and the disc broadly flattened ante-

riorly. The femoral tooth is small and triangular. The male has the fifth ventral

segment broadly depressed along the middle behind, and also feebly emarginate at

the apex.

Acapulco, Jalapa (Hodge), Orizaba (Lesuewr4, Sallé), Playa Vicente, Toxpam, Vera

Cruz (Sallé); GuatTeMALa, near the city (Salvin) ; Nicaragua, Chontales (Belt, Janson).

Of this species we have a long series from Mexico, and also four specimens from

further south. The chief characters of 0. mexicanus are the long, subcylindrical

prothorax, the distinctly seriate-punctate elytra, with obliquely truncated humeri, the

somewhat abundant blackish setosity, the rather short rostrum, the small, triangular,

femoral tooth, and the somewhat curved, stout, anterior tibie. The fifth ventral

segment is slightly emarginate at the apex in the male, and feebly bisinuate in the

female. Three females, from Playa Vicente, Jalapa, and Chontales respectively, have

the prothorax more rounded at the sides, and they may not really belong here. The

less elongate shape and shorter rostrum separate O. mexicanus from O. apioniformis,

O. vicinus, and O. tenuirostris, and the obliquely truncated elytral humeri distinguishes

it from O. oculatus. I have seen one of the specimens described by Rosenskoeld.

53. Otidocephalus angusticollis, sp. n.

Elongate, black, shining; clothed with scattered, rather short, erect, blackish setze, which on the elytra are

arranged in a single series down each interstice, the prothorax with a few long, fine, white, decumbent

hairs at the base, the vestiture of the scutellum and under surface white, the legs with intermixed white

and blackish hairs. Head sparsely punctate, shallowly foveate between the eyes, which are moderately

large and somewhat widely separated ; rostrum much shorter than the prothorax, punctato-sulcate at the

sides, smooth along the middle; antenne with joint 2 of the funiculus slightly longer than 3, 3-7 sub-

equal in length, the club ovate. Prothorax elongate, convex, much narrowed behind, the surface with

a few fine scattered punctures, a large space on the flanks impunctate. Elytra moderately long, convex,

flattened on the disc anteriorly, very much wider than the prothorax, rapidly widening to the middle,

and there fully twice its width, conjointly emarginate at the base, the humeri very obtuse; finely

punctate-striate, the interstitial punctures scarcely visible. Femora each with a short triangular tooth.

Anterior tibie strongly sinuate within.

Length 6, breadth 24 millim. (9 ?)

Hab. Nricaracva, Chontales (Belt).

One specimen. This insect resembles 0. apioniformis, but has the prothorax much

narrowed behind and cylindrical in front, the elytra hollowed at the base and with

very obtuse humeri. The smaller femoral tooth and the absence of the regular rows

of white hairs on the apical declivity of the elytra separate it from O. divisus.

54. Otidocephalus gibbicollis, sp. n.

Moderately elongate, shining, black, the legs and antenne picecus ; sparsely clothed with long, erect, blackish

sete, which on the elytra are arranged in a row along each interstice and are intermixed with a few

white hairs at the apex; the vestiture of the scutellum and under surface white, the legs with intermixed

white and blackish hairs. Head almost smooth, the eyes large and rather widely separated; rostrum

stout, shorter than the prothorax, punctured and bisulcate at the sides, smooth along the middle.

Prothorax long, narrow, and laterally compressed, gibbous anteriorly, narrowed behind, the surface with

a few widely scattered fine punctures. Elytra moderately long, somewhat gibbous, much wider than the

prothorax, widening to the middle, the humeri obliquely truncated in front ; very finely seriate-punctate,

’ the. punctures not very closely placed, the interstices each with a scattered row of minute setigerous

impressions. Femora each with a rather small, acute, triangular tooth. Anterior tibie feebly sinuate

within.

Length 44, breadth 17 millim.

Hab. Mexico, Sierra de Durango? (ex coll. Flohr).

One specimen. The relatively long, narrow, gibbous prothorax, the rather short,

inflated, very finely seriate-punctate elytra, the long blackish setosity, and the short trian-

cular femoral tooth, are the chief characters of this obscure species, The less rounded

sides of the prothorax and the smaller femoral tooth separate O. gibdicollis from

O. longipilis; and the shorter elytra, with more prominent humeri and longer sete,

distinguish it from O. angusticollis.

55. Otidocephalus adspersus, sp. n.

Elongate, shining, black, the funiculus reddish; the head and prothorax clothed with fine, scattered, blackish

and white hairs, the elytra with a row of erect blackish sete along each interstice, intermixed with

scattered, squamiform, white hairs, the vestiture of the scutellum and under surface white, the legs

with intermixed white and blackish hairs. Head sparsely punctate, the eyes moderately large and some-

what widely separated; rostrum in the 9 nearly as long as the prothorax, shorter in the ¢, punctato-

sulcate at the sides, smooth along the middle; antenne with joint 2 of the funiculus much longer than 3,

the club oblong-ovate and nearly as long as joints 2-7 united. Prothorax long, subcylindrical in front,

much narrowed behind, very sparsely, coarsely punctate on the dise (more closely so in the ?), the

punctures becoming crowded at the base, a space on the flanks impunctate in the d. Elytra moderately

long, much wider than the prothorax, convex, flattened on the disc at the base, gradually widening to

to the middle, the humeri obliquely truncate in front; punctate-striate, the interstices flat or feebly

convex, uniseriate-punctate. Fifth ventral segment arcuate-emarginate at the apex in the g¢. Femora

each with a small triangular tooth. Anterior tibie strongly sinuate within.

Length 51-6,1,, breadth 2-24 millim.

Hab. Mexico, Juquila in Oaxaca (Sallé; Mus. Dresden).

Two males and two females, one of which belongs to the Dresden Museum. A

moderately elongate form, the elytra punctate-striate, with scattered coarse white

hairs intermixed with the black sete, the antennal club long, the femoral tooth small

and triangular, the fifth ventral segment emarginate in the male. It is not unlike

O. brevisetis, but the elytra have less prominent humeri, uniseriate-punctate interstices,

longer setosity, and narrower squamiform hairs, the legs are not so stout, &c. The

intermixed coarse white hairs on the elytra separate it from the still more nearly allied

O. mexicanus.

56. Otidocephalus senex.

Otidocephalus senex, Chevr. Ann. Soc. Ent. Fr. 1877, p. 176°.

Hab. Muxico, Cordova!, Toxpam (Sallé), Sierra de Zongolica (coll. Becker).

The type of this insect cannot now be found at Stockholm, but we have three

specimens of it from Sallé, and there is another in Mr. R. Becker’s collection in Berlin.

Amongst the small species with short, convex elytra, it may be recognized by the

sparse black setosity intermixed with a few rather coarse, rigid, white hairs, the very

fine or almost obsolete seriate punctuation, and the rather small, triangular, femoral

tooth. The head is coarsely punctured above, smooth near the eyes, and foveate

between them. ‘The prothorax is subglobose in front, quite smooth at the sides, with

a few scattered punctures only on the disc. The humeri of the elytra are obliquely

truncated in front and somewhat swollen.

57. Otidocephalus zneus, sp. n.

Elongate, very shining, nigro-zeneous; the head, the basal margin of the prothorax, the scutellum, the under

surface, and legs clothed with white hairs, the prothorax and elytra with a few, fine, scattered, suberect,

blackish sete, those on the elytra arranged in an interrupted row along the interstices 1, 3, and 5.

Head foveate and rugosely punctured between the eyes, for the rest sparsely punctate; eyes large and

moderately prominent, somewhat widely separated; rostrum short and stout, very much shorter than

the prothorax, depressed at the base above, rugosely punctate and shallowly sulcate laterally, smooth

along the middle to near the tip; antenne with joints 2-7 of the funiculus short, 1 about twice as long

as 2, the club ovate. Prothorax moderately long, cylindrical, narrowed at the base, the disc with a few

widely scattered punctures, the basal margin closely punctate, the flanks smooth. Elytra moderately

long, convex, much wider than the prothorax, widening to the middle, subtruncate at the base; very

finely seriate-punctate, the interstices flat, 1, 3, and 5 each with a row of scattered punctures. Femora

— each with a small, narrow tooth. Anterior tibiee feebly sinuate within. Tarsal claws feebly appendiculate.

the upper surface is smoother and has an eneus lustre; the prothorax is less elongate

and has a close fringe of white hairs at the base; the suberect blackish sete are but

few in number; the setigerous punctures near the suture of the elytra are a little

coarser than those of the strie, and more numerous than on the third and fifth

interstices ; the femoral tooth is small. The rostrum is very short and stout.

58. Otidocephalus levipennis, sp. n.

Moderately elongate, shining, black, the antenns sometimes in part ferruginous; clothed with long, fine, erect,

blackish sets, which are seriately arranged on the elytra, the latter sometimes with a few white hairs on

the apical declivity and along the outer margin, the vestiture of the base of the prothorax, scutellum, and

under surface white, the legs with intermixed white and blackish hairs. Head sparsely, minutely

punctate, feebly foveate between the eyes, which are moderately large and rather narrowly separated in

the ¢, more distant in the 2 ; rostrum shorter than the prothorax, moderately stout, punctato-sulcate

at the sides, smooth along the middle; joint 2 of the funiculus slightly longer than 3. Prothorax long,

globose in front, narrowed and constricted behind, very sparsely, minutely punctate, except along the

basal margin, which is distinctly punctured. Elytra moderately long, convex, flattened on the disc at

the base, much wider than the prothorax, widening to the middle, the humeri obtuse, obliquely truncated

in front; the surface almost smooth, the usual seriate punctures obsolete or minute, the setigerous

impressions very minute. Femora each with a small, narrow tooth. Anterior tibis sinuate within.

Var.? The antenne entirely testaceous; the elytral sete finer and paler. .

Length 24-42, breadth ,®-14 millim. (¢ Q.)

Hab. Mexico (Sallé), Tapachula (Hége), Motzorongo (Flohr, in Mus. Berol.), Teapa

(Champion); Nicaragua, Chontales (Belt) ; Costa Rica, San Carlos, Tucurrique (J/us,

Dresden); Panama, Bugaba, Volcan de Chiriqui, David (Champion).

A common species within our limits, varying greatly in size, and perhaps previously

described from South America. It is distinguishable from O. albomarginatus and most

of the other allied forms with a narrow femoral tooth by the almost smooth elytra, and

the erect setosity of the upper surface. The sete in fresh specimens are abundant on

both the prothorax and the elytra, but they are easily abraded. ‘The variety (?) is

represented by various specimens from ‘Teapa, Teleman, and Chacoj. In one of several

individuals from Zapote the elytra have a few short white hairs scattered amongst the long

dark sete. ‘Two examples, from Chacoj and Panzos respectively, have a more elongate

antennal club, but I am unable to separate them satisfactorily from the others.

59. Otidocephalus megalops, sp.n. (Tab. XIII. fig. 25, 3.)

Moderately elongate, black, shining; sparsely clothed with long, fine, suberect, bristly, white hairs, with a

few intermixed blackish sete on the prothorax and anterior legs, and sometimes on the elytra also, the

hairs on the latter arranged in a single series throughout the length of each interstice, becoming more

numerous towards the apex, the vestiture of the scutellum, under surface, and legs white. Head almost

smooth, very deeply foveate between the eyes above and slightly constricted behind them, the eyes

large, convex, and narrowly separated in the ¢, less prominent and more distant in the 9; rostrum

stout, much shorter than the prothorax, punctato-sulcate at the sides, smooth along the middle; antenne

with joints 2-7 of the funiculus subequal in length, the club ovate. Prothorax long, globose in front,

much narrowed and constricted behind, the surface with minute, widely scattered punctures. Elytra

moderately long, convex, much wider than the prothorax, widening to the middle, the humeri obliquely

truncated in front; very finely seriate-punctate, the punctures (except those of the first row) widely

separated from each other, the interstices flat and each excessively minutely uniseriate-punctate. Legs

elongate; femora each with a narrow, acute tooth; anterior tibize sinuate within.

Length 34-5, breadth 14-2 millim. (¢ 2.)

Hab, Panama, Bugaba, Caldera (Champion).

Amongst its nearest allies the present species may be identified by the large and very

prominent eyes in the male, the smooth, deeply foveate head, the suberect, long, white

hairs of the upper surface, the somewhat widely separated seriate punctures on the

elytra, and the slender femoral tooth. Nine specimens, varying greatly in size.

60. Otidocephalus similis, sp. n.

Moderately elongate, black, shining; clothed with scattered, long, erect, blackish sete, which on the elytra are

arranged in a single row along each interstice, the elytra with a few white hairs at the extreme tip, the

vestiture of the scutellum and under surface white, the legs with long intermixed white and blackish

hairs. Head almost smooth, slightly constricted behind the eyes, and deeply foveate between them, the

eyes prominent, moderately large, and somewhat narrowly separated; rostrum much shorter than

the prothorax, punctato-sulcate, subcarinate along the middle. Prothorax long, globose in front, much

narrowed and constricted behind, the surface with a few minute widely scattered punctures. FElytra as

in O. megalops; obsoletely seriate-punctate, the interstitial punctures very minute. Femora each with

a long, narrow, acute tooth. Anterior tibie strongly sinuate within.

Length 33, breadth 13 millim. (2 ?)

Hab. GuatemaLa, Panima and Chacoj in Vera Paz (Champion).

This is the Guatemalan form of O. megalops, differing from it in the less abundant

and blackish setosity of the upper surface, the smaller and less prominent eyes, and the

longer and stouter femoral tooth. The almost smooth elytra separates O. similis from -

the other allied species with deep frontal fovea; and the presence of the latter distin-

guishes it from 0. levipennis and O. longipilis, the femoral tooth also being smaller

than in the last-named insect.

61. Otidocephalus albomarginatus.

Otidocephalus albomarginatus, Chevr. Ann. Soc. Ent. Fr. 1877, p. 177°.

Moderately elongate, shining, black, the antenne (the club excepted) and tarsi often more or less testaceous ;

sparsely clothed with long hairs, which on the elytra are white and bristly, intermixed with blackish sete

on the disc, and arranged in a single series on each interstice, the vestiture of the scutellum and under

surface white, the legs with intermixed white and blackish hairs. Head sparsely punctate, more or less

foveate or sulcate between the eyes, which are moderately large and not very widely separated ; rostrum

stout, shorter than the prothorax, punctato-sulcate at the sides, smooth along the middle. Prothorax

long, gibbose in front, narrowed and constricted behind, very sparsely punctate. Elytra comparatively

~ short, much wider than the prothorax, widening to the middle, convex, flattened on the disc at the base,

the latter subtruncate, the humeri obliquely truncated in front; seriate-punctate, striate towards the

suture, the interstices flat, and each with a scattered series of very minute punctures. Femora each with

a small, narrow, spiniform tooth. Anterior tibiee feebly sinuate within.

Found in plenty at Duefias. In this species the scattered white bristly hairs on the

elytra are usually intermixed with blackish sete, the latter predominating on the disc

in the typical Mexican specimens; the elytra themselves are conspicuously seriate-

punctate, the frontal impression is small, the femoral tooth is small and narrow, and

the tarsi are often testaceous. The small femoral tooth separates O. albomarginatus

from 0. setiger, O. cavifrons, and other similar forms, and the distinctly seriate-punctate

elytra distinguishes it from O. levipennis.

62. Otidocephalus core, sp. n.

Moderately elongate, shining, black, the antenne (the club excepted) and the tarsi in part ferruginous ;

sparsely clothed with rather long, fine, white, decumbent hairs, which on the prothorax, elytra, and legs

are intermixed with erect blackish sete. Head convex and coarsely punctured, smoother and flattened

between the eyes, which are moderately large and widely separated ; rostrum stout, curved, depressed at

the base above, a little shorter than the prothorax, punctato-sulcate at the sides, smooth along the middle ;

antennal club ovate. Prothorax long, convex, much narrowed behind, and also narrowed and slightly

constricted in front, coarsely, rather closely punctate. Elytra moderately long, convex, much wider than

the prothorax, gradually widening to near the middle, subtruncate at the base, the humeri obtuse ;

coarsely seriate-punctate, the punctures placed in shallow strize, the interstices feebly convex, very

minutely and irregularly uniseriate-punctate. Femora each with a small, narrow tooth. Anterior tibie

strongly sinuate within.

Length 4, breadth 12 millim.

Hab. Mexico, El Cora in Tepic (coll. Becker).

Two specimens. This insect is perhaps nearest allied to 0. albomarginatus, differing

from that species in the coarse punctuation of the upper surface, the anteriorly

narrowed prothorax, &c, The small femoral tooth separates it from O. setiger,

O. cavifrons, and others.

63. Otidocephalus comatus, sp. n. |

Moderately elongate, black, shining; clothed with an abundant, very long, erect, fine, blackish setosity

intermixed with a few white hairs, the sete: on the elytra arranged in a single row along each interstice,

the vestiture of the scutellum and under surface white, the legs with long, white, projecting hairs inter-

mixed with a few blackish ones. Head sparsely punctate, the eyes moderately large and not very widely

separated ; rostrum stout, shorter than the prothorax, punctato-suleate at the sides, smooth along the

middle; antenn with joint 2 of the funiculus slightly longer than 3, the club ovate. Prothorax long,

convex, narrowed and subcylindrical behind, very sparsely punctate, the punctures becoming crowded at

the base only, a space on the flanks impunctate. Elytra moderately long, not very convex, flattened on

the disc at the base, wider than the prothorax, widening to the middle, the humeri somewhat obliquely

truncated in front; very finely seriate-punctate, the punctures not very closely placed, the interstices

minutely uniseriate-punctate. Femora each with an acute narrow tooth. Anterior tibiz curved ex-

ternally and strongly sinuate within.

OTIDOCEPHALUS. 263

One specimen. This insect has an abundant, fine, blackish setosity, as in O. hystri-

cosus, but there are very few intermixed white hairs; the elytra are also much

smoother, with the interstices uniseriate-punctate, and the prothorax is longer and

relatively broader. It is a little more elongate than O. albomarginatus and has less

convex elytra.

64. Otidocephalus crinitus, sp. n.

Moderately elongate, narrow, piceous (immature), shining ; sparsely clothed with long, bristly, white hairs,

which on the elytra are suberect, intermixed on the disc with a few blackish sete, and arranged in a

single series along each interstice, becoming more numerous towards the apex, the vestiture of the

scutellum, legs, and under surface white. Head rather coarsely punctate, the eyes large, prominent, and

widely separated ; rostrum stout, much shorter than the prothorax, punctato-sulcate. Prothorax mode-

rately long, convex, much narrowed and constricted behind, somewhat coarsely punctate, a narrow space

along the middle and a large space on the flanks impunctate. Elytra oblong-oval, much wider than the

prothorax, gradually widening to the middle, not very convex, the humeri a little swollen, and obliquely

truncate in front; distinctly seriate-punctate, the punctures closely placed, the interstices very minutely

uniseriate-punctate. Fifth ventral segment bisinuate at the apex, the apical margin slightly produced in

the middle. Legs comparatively short and stout; femora each with a small narrow tooth; anterior

tibie strongly sinuate within.

Hab. Mexico, Toxpam (Sal/é),

One immature specimen, incorrectly named O. albomarginatus, Chevr., in the Sallé

and O. longicollis, from which the present species differs in its small size and less

elongate shape, the relatively larger eyes, and the narrow femoral tooth.

Hab. Mrxico23 4, Orizaba (coll. Chevrolat 1), Toxpam (Sa//é).

There is a single, broken, immature specimen of this species in the Sallé collection.

It is easily distinguishable by its peculiar coloration, the head and prothorax being

black, and the elytra and the rest of the body testaceous; the basal margin of the

prothorax is thickly clothed with white pubescence, and the rest of the upper surface

with long scattered setee; the elytra are seriate-punctate ; the femoral tooth is small

and spiniform.

arranged in a single series on each of the interstices 1, 3, 5, and 7, the base of the prothorax, the scutellum,

legs, and under surface with white hairs, the legs with a few blackish ones intermixed. Head almost

smooth, constricted behind the eyes, which are very large, prominent, and almost contiguous above;

rostrum very stout, shorter than the prothorax, rugosely punctate, smooth along the middle, the scrobes

straight. Prothorax long, globose in front, narrowed and constricted behind, the surface with a few

minute scattered punctures, a space on the flanks impunctate. Elytra comparatively short, convex,

subparallel in their basal half, much wider than the prothorax, the humeri obliquely truncate in front

and rather prominent; very finely seriate-punctate, the alternate interstices each minutely uniseriate-

punctate. Femora each with a small, narrow, acute tooth. Anterior tibie sinuate within.

Length 33-32, breadth 13-13 millim.

Hab. Mexico, between Oaxaca and Acapulco! (Mus. Holm.), Oaxaca (Hége).

Two specimens, agreeing with the type, which I have seen. In this small species

the eyes are very large, prominent, and almost contiguous above, the elytra are very

little wider at the middle than at the base, and the femoral tooth is small and narrow,

these characters separating O. boops from most of its allies with blackish sete only

on the elytra. O. levicollis, Horn, which ranges from New York to Texas, is very

like the present species; but in the former the head is not constricted behind the

eyes, the elytra are less finely seriate-punctate, and the blackish sete are intermixed

with bristly white hairs. O. megalops has the eyes less approximate and the front

foveate.

67. Otidocephalus crassirostris, sp.n. (Tab. XIII. fig. 27, 3.)

Moderately elongate, shining, black, the antenne (the club excepted) ferruginous, the tarsi piceous or rufo-

piceous ; clothed with long, scattered, erect, blackish sete, which on the elytra are arranged in a single

series along each of the dorsal interstices, the head, the base of the prothorax, the scutellum, and under

surface with white hairs, the legs with intermixed white and blackish hairs. Head almost smooth, the

eyes very large and subcontiguous; rostrum short, exceedingly stout, curved above (when viewed in

profile), punctato-sulcate at the sides and apex, smooth along the middle, and with a short median sulcus

towards the tip, the scrobes sinuous and very deep; antennz with joints 2-7 of the funiculus subequal in

length, the club ovate. Prothorax long, globose in front, narrowed and constricted behind, the base

coarsely punctate, the rest of the surface with minute widely-scattered punctures. Elytra moderately

long, convex, much wider than the prothorax, widening to the middle, the humeri obliquely truncate in

front; the surface almost smooth, the usual seriate punctures obsolete or indistinct. Femora each with

a narrow, acute tooth. Anterior tibie strongly sinuate within.

Length 31-34, breadth 13-13 millim. (d 2.)

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

Numerous examples. The extremely stout, short rostrum, with deep sinuous

scrobes, the large, subapproximate eyes, the almost smooth elytra, with blackish sete,

and the narrow femoral tooth, distinguish this small species from the allied forms. It

is, however, very nearly related to O. levipennis, but the latter has a less thickened

rostrum and the eyes more separated. ‘The less prominent eyes, the shorter rostrum,

with sinuous scrobes, and the smoother elytra, separate it from the Mexican

O. boops.

Length 23, breadth 1 millim. (¢ 9.)

Hab. Mexico, Motzorongo in Vera Cruz (Flohr, in Mus. Berol.: 2), Teapa in

Tabasco (H. H. Smith: ¢ ).

Two specimens, assumed to be sexes of the same species, the one from Teapa being

rather immature and wanting the white hairs on the elytra. This insect resembles

O. levipennis, but is smoother, the sete are finer and very few in number, and the eyes

in the male are almost contiguous.

69. Otidocephalus puncticeps, sp. n.

Comparatively short, black, shining, the antenne (the club excepted) and tarsi more or less ferruginous ; the

prothorax and elytra with a few widely scattered, semierect, rather coarse, bristly, white hairs, the

vestiture of the scutellum, legs, and under surface also white. Head convex, coarsely, closely punctate

above, smooth near the eyes and sulcate between them, the eyes moderately large and somewhat narrowly

separated ; rostrum stout, much curved (appearing depressed at the base above when viewed in profile),

shorter than the prothorax, punctato-sulcate at the sides and smooth along the middle. Prothorax

moderately long, globose in front, narrowed and constricted behind, punctured at the base and apex, and

for the rest almost smooth. Scutellum very small. Elytra comparatively short, gibbous, much broader

than the prothorax and rapidly widening towards the middle, subtruncate at the base, the humeri obtuse,

the surface almost smooth. Femora each witha very small narrow tooth. Anterior tibiz sinuate within.

Length 2,9,-34, breadth 13-13 millim.

Hab. Mexico, Motzorongo in Vera Cruz (coll. Becker).

Two specimens, probably male and female. Broader than O. levis, the head coarsely

punctured, the eyes less contiguous, the elytra more convex and clothed with a few

bristly white hairs only. Less elongate, more convex, and smoother than 0. seniculus,

and with the head much more coarsely punctured. ‘The scutellum is quite small, very

little larger than in Oopterinus castaneipennis.

Otidocephalus seniculus, Chevy. Bull. Soc. Ent. Fr. 1878, p. ciii*.

Hab. Mexico, Cordova!, Toxpam (Sallé), Teapa (H. H. Smith).

Var.? The head somewhat coarsely punctate, the elytra finely seriate-punctate.

Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith).

Of this insect we have two specimens from the Sallé collection agreeing with the

type, and another, sent us by Mr. H. H. Smith, from Teapa. It has the elytra almost

smooth, and clothed with a few widely scattered, semierect, white, squamiform hairs,

the usual dark sete being absent. ‘The femoral tooth is small and narrow. The

var.? is represented by two examples from Chilpancingo, and should perhaps be

separated as specifically distinct. |

71. Otidocephalus flavipilis, sp. n.

Moderately elongate, shining, varying in colour from black, with the elytra castaneous and the antenne and legs

in part ferruginous, to entirely ferruginous ; clothed above with long, fine, suberect, scattered, yellowish,

bristle-like hairs, which are serially arranged on the elytra, the vestiture of the scutellum, legs, and under

surface also yellowish, the denser pubescence at the sides of the meso- and metasternum whitish. Head

convex, coarsely punctured above, almost smooth near the eyes, which are moderately large and somewhat

widely separated ; rostrum shorter than the prothorax, depressed at the base above, punctato-sulcate at the

sides, smooth along the middle. Prothorax long, globose in front, much narrowed and constricted behind,

very sparsely punctate, the punctuation becoming coarse and close along the basal margin. Elytra

comparatively short, somewhat gibbous, much wider than the prothorax, widening to the middle, truncate

at the base, the humeri rounded, the surface almost smooth. Femora each with a small, acute, narrow

tooth. Anterior tibie strongly sinuate within.

Var.? Head almost smooth, the elytra with fewer hairs.

Length 23-33, breadth 1-13 millim.

Hab, Guatemana, San Juan, Senahu, and Teleman in Vera Paz (Champion);

PaNnaMA, Bugaba, Volcan de Chiriqui (Champion).

The almost smooth, castaneous or ferruginous elytra, the long, yellowish, suberect

hairs of the upper surface, and the small, narrow, femoral tooth, distinguish this

species amongst its allies. Of the fourteen specimens obtained of the typical form,

four only are from Chiriqui, these being almost entirely ferruginous. The variety (?)

is represented by five examples from Chiriqui, but as one of the three individuals

obtained at Teleman is intermediate I have not ventured to name it.

72. Otidocephalus versicolor, sp.n. (Tab. XIII. figg. 29, 29 a, 3.)

Moderately elongate, very shining, black, the head, rostrum, antennal scape, cox, and mesosternum rufous,

the rest of the antenne and the legs piceous ; the prothorax and the disc of the elytra with a few very

long, erect, scattered, blackish sete, the vestiture of the scutellum, legs, and under surface white.

Head with the upper portion convex and coarsely punctate, and separated from the lateral portion by

a sharp ridge, quite smooth between and immediately above the eyes, which are comparatively small;

rostrum short and very stout, barely half the length of the prothorax, depressed at the base above

(appearing curved in profile), punctato-sulcate at the sides, smooth along the middle, the scrobes deep and

oblique; antenne short, joints 2-7 of the funiculus very short, together about as long as the club, which

is ovate. Prothorax elongate, globose in front, narrow and subcylindrical behind, rather closely and

coarsely punctate, except along a narrow space down the middle, the lower part of the flanks smooth.’

Elytra about twice as long as, and much wider than, the prothorax, gibbous, compressed at the sides

below the shoulders, rapidly widening to the middle and narrowing thence to the apex, the humeri

rounded ; the surface apparently smooth (viewed under a high power the usual series of punctures are

just visible), the sete arranged in three rows on the disc of each elytron. Legs comparatively long;

femora each with a very short, fine tooth; anterior tibie almost straight.

Length 34, breadth 13 millim.

Hab, GuatTeMALa, San Juan, to the north of the Polochic Valley (Champion).

OTIDOCEPHALUS.—OOPTERINUS. 267

One specimen. This curious little species seems to be a near ally of the similarly-

coloured Brazilian O. rujicollis, Chevr. (1=0. bicolor, Rosensk.), which is described as

having the prothorax tuberculate at the base and the rostrum straight and cylindrical,

characters not applying to O. versicolor. In the latter the convex, coarsely punctured

portion of the head is separated from the smoother, flattened, lateral portion by a sharp

ridge, a peculiarity not mentioned in Chevrolat’s diagnosis of O. rujficollis.

73. Otidocephalus bidentatus, sp.n. (Tab. XIII. figg. 30, 30a.)

Moderately elongate, black, shining ; clothed with long, scattered, erect, blackish sete and intermixed, rather

coarse, decumbent white hairs, the latter confined to the sides of the prothorax, and to the outer half and

the apical declivity of the elytra, and arranged in an irregular double or treble row on the interstices 2, 4,

6, 8, and in a single row on the others, the vestiture of the scutellum and under surface white, the legs

with intermixed white and blackish hairs. Head very sparsely punctate, flattened above the eyes and

obsoletely foveate between them, the latter moderately large and not very widely separated; rostrum

considerably shorter than the prothorax, punctato-sulcate at the sides, smooth along the middle; antenne

with joints 3-7 of the funiculus short, 2 a little longer than 3, the club ovate. Prothorax moderately long,

cylindrical in front, and a little narrowed and constricted behind, somewhat closely pnnctate at the base

and apex, the rest of the disc with a few widely scattered punctures only, the flanks smooth. Elytra

very much wider than, and two and one-half times the length of, the prothorax, moderately convex,

flattened on the disc anteriorly, very gradually widening to the middle, broadly subtruncate at the base,

the humeri prominent; finely seriate-punctate, the interstices 1, 3, 5, 7,9 each with a single, and the

others with an irregular double or treble, row of minute punctures. Femora each with two narrow

parallel-sided teeth—the inner one long and obliquely truncated at the apex, the outer one shorter and

narrower and also truncated. Anterior tibie strongly sinuate within, rounded externally in their

basal half,

Length 43, breadth 2 millim. (3?)

Hab. Mexico (Flohr, in Mus. Berol.).

A very remarkable species, differing from all others of the genus known to me in

the bidentate femora. ‘The decumbent white hairs on the outer interstices of the

elytra show a tendency to form small fascicles, but this may be due to abrasion. ‘The

single example seen is contained in the Berlin Museum.

OOPTERINUS.

Oopterinus, Casey, Ann. N. York Acad. Sci. vi. p. 438 (1892).

The type of this genus is Otidocephalus perforatus, Horn, of the United States. It

includes the apterous Otidocephalids, with more or less connate, ovate elytra (the

humeri being completely effaced and the base of the elytra very little wider than that of

the prothorax), which are widest before the middle, the scutellum minute or invisible

(as in Lemomerus, Kirsch), and the eyes coarsely facetted and well separated. The

rostrum is depressed at the base above. The first two ventral segments are connate.

The tarsal claws are feebly appendiculate. The males of some of the species have the

first ventral segment depressed or sulcate down the middle. In 0. bactrianus the

Length 34, breadth 1} millim. (¢ @.)

Hab. Mexico, Juquila in Oaxaca (Flohr, mus. nostr. et Berol.).

Two specimens. Distinguishable from the Guatemalan 0. gibbipennis by the visible

scutellum, the less gibbous elytra, which are much more finely punctured at the sides,

the smoother prothorax, and the non-metallic upper surface. The less elongate elytra,

the smoother prothorax, &c., separate it from 0. piliferus.

3. Oopterinus bactrianus, sp. n. (Tab. XIV. figg. 4, 4a.)

Comparatively short, moderately shining, piceous or nigro-piceous, the antennz and the legs in part ferruginous,

the tarsi paler ; almost glabrous above, the scutellum, under surface, and legs sparsely clothed with fine

rather long, adpressed, yellowish-white hairs. Head convex, rather sparsely, somewhat coarsely punctate,

sulcate between the comparatively large eyes; rostrum very stout, curved, shorter than the prothorax,

rugosely punctured and longitudinally wrinkled. Prothorax much longer than broad, gibbous anteriorly

and much narrowed behind, coarsely and confluently punctured at the base, and also coarsely punctured

Group ERODISCINA.

Erodiscides, Lacordaire.

The species of this group are nearly all Tropical American, and range as far north

as Florida. The four recognized genera are feebly differentiated, and it is very doubtful

if they can be maintained as distinct when the whole of the South-American species

are studied.

In this curious genus, which includes a few Tropical-American species * and also

one from Java, the knees and the apex of each elytron are armed with a long spine,

the rostrum is slender and at least as long as the body, the second joint of the funiculus

is not or very little longer than the third, and the tarsal claws are simple. I follow

Chevrolat in adopting Pascoe’s name, though it was simply used by him to replace that

of Toxeutes, Schénh., in the wide sense, on account of the latter being preoccupied.

The Tropical-American forms referred to this genus* have the rostrum slender,

feebly curved, and as long as or longer than the body, with the scrobes oblique and

evanescent behind, the antennal scape much thickened at the apex, the second joint

of the funiculus and the first tarsal joint both very elongate (the former being nearly

three times as long as the third joint, and the latter fully half the length of the tibia),

the eyes well separated above, the scutellum small, and the prothorax plicate on each

side at the base. In the single species now added the tarsal claws have a short tooth

at the base.

foveate between the eyes, which are large, coarsely facetted, and somewhat distant above; rostrum

slender, as long as or longer than the body in the 9, a little shorter in the d, finely punctate in its

basal half, and almost smooth thence to the apex, the basal portion asperate beneath in the g, the scape

the rostrum in the 2, and at the middle in the dg, slender, joint 2 of the funiculus elongate, twice as long

as 3, the scape thickened at the tip. Prothorax much longer than broad, convex, rounded at the sides,

constricted in front, smooth, except for some scattered punctures at the apex; the short basal portion

transversely depressed, plicate at the sides, which are parallel as seen from above. Llytra elongate, a

Chevrolat takes Torophorus fasciatus, Gyll. (=tantalus, Rosensk.), from Tropical

South America, as the type of Zudovix, and the species now added is a nearly allied

form. These insects have the rostrum slender, curved, and in the male much shorter

than in the female (in which sex it is as long as the body), the scrobes in both sexes

extending as far as the eyes, which are well separated above, the second joint of the

funiculus nearly three times as long as the third, the scutellum comparatively large,

and the tarsal claws armed with a long slender tooth. ‘The scattered vestiture is

coarse and squamiform, instead of long and bristly as in Hrodiscus, &c.

Elongate, narrow, subcylindrical, shining, rufous, the basal half of the rostrum, the head, the scutellum, two

fascize on the elytra—one at the base, the other, wider, beyond the middle,—the meso- and metasternum,

the coxse, and the knees broadly, black ; the elytra with scattered, coarse, white, semierect, squamiform

hairs, the meso- and metasternum and the sides of the abdomen somewhat thickly clothed with elongate,

adpressed, white scales. Head small, convex, smooth, faintly foveate between the eyes, which are large

and somewhat widely separated; rostrum slender, curved, a little shorter than the elytra, smooth, the

antenne inserted about the middle, joint 2 of the funiculus elongate, as long as 3-5 united. Prothorax

convex, a little longer than broad, rounded at the sides, much narrowed and constricted both at the base

and apex, sparsely, rather coarsely punctate, the punctuation becoming coarser on the flanks, a space down

the middle of the disc impunctate. Elytra elongate, scarcely wider than the prothorax, subparallel in

their basal half, flattened on the disc, the humeri obtuse ; rather coarsely seriate-punctate, the interstices

narrow, with widely scattered, coarse punctures. Meso- and metasternum coarsely punctate, the base of

the abdomen also with a few coarse punctures. Ventral segments 1, 2, and 5 more or less depressed

along the middle, the depression on 5 broad, rugulosely-punctate and pubescent at the tip. Legs long ;

Hab. Panama, David in Chiriqui (Champion: ¢ ).—Gutana, Cayenne (Mus. Brit.: 2 ).

Perhaps a variety of L. fasciatus, from which it differs in the shorter rostrum of

the g, the shorter prothorax, the bifasciate elytra, and the black head, basal half of

the rostrum, and knees. The description is taken from two males from Chiriqui, and

there is a female from Cayenne, in the British Museum, with a very much longer

rostrum, that doubtless belongs to the same species.

Species of this genus have been described from South America, Cuba, Florida, and.

Java. They are chiefly recognizable by the large subcontiguous eyes, the moderately

long second joint of the funiculus, and the small narrow scutellum. The rostrum in

some of them is as long as the body, at least in the female, and is often thickened

towards the base. The tarsal claws are either toothed or simple. ‘The males usually

have the first ventral segment protuberant, lamellate, or bituberculate in the middle

at the apex. Of the six Central-American representatives, five are treated as new;

they may be grouped thus :—

Central-American forms.

2. Erodiscus appendiculatus, sp. n. (Tab. XIV. fig. 11, profile of abdo-

men &c., 3.)

Elongate, shining, nigro-piceous or black, the antenne, the rostrum, the femora at the base and apex, the tibie,

and tarsi, more or less rufo-piceous; the prothorax, the alternate interstices of the elytra, the under

surface, and legs sparsely clothed with very long, erect, yellowish, bristly hairs. Head minutely punctate,

the eyes very narrowly separated above; rostrum feebly curved, a little shorter than the body, slightly

thickened towards the base, longitudinally rugulose in its basal half and much smoother thence to the

apex; the antenne inserted near the middle in both sexes, joint 2 of the funiculus much longer than 3.

Length 4-5, of the rostrum 22-34, breadth 13-17 millim. (¢ @.)

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

Five males and four females, all from the forest-clad mountains north of the Polochic

Valley. This insect is readily recognizable by the long, truncated process of the first

ventral segment in the male. Apart from this character, the sparsely punctate disc of

the prothorax and the absence of the tooth on the anterior tibie separate it from

Ei. antilope.

3. Erodiscus lamellatus, sp. n. (Tab. XIV. figg. 12, ¢; 13, 13a, 2.)

Varying in colour from black to rufo-piceous ; the general structure, sculpture, and vestiture as in ZH. appendi-

culatus, except that the punctuation of the prothorax is usually closer on the disc (leaving always a smooth

space down the middle) and that of the abdomen sparser; the first ventral segment in the ¢ raised and

broadly truncato-lamellate in the middle at the apex (fig. 12).

Length 3-5, of the rostrum 13-33, breadth 1-13 millim. (d @.)

E. antilope. EE. granatensis, Chevr., from Honda, Colombia, is described as having

a similarly sculptured prothorax.

4, Hrodiscus bituberculatus, sp.n. (Tab. XIV. fig. 14, head and rostrum, ¢.)

Elongate, shining, nigro-piceous or piceous; the alternate elytral interstices each with a row of very long,

erect, whitish, bristly hairs. Head smooth, the eyes almost contiguous above; rostrum feebly curved,

swollen at the middle beneath in the ¢, a little shorter than the elytra in both sexes, with the basal half

much thickened, laterally sulcate, and longitudinally rugulose, the apical half almost smooth ; antenne in

both ¢ and @ inserted at about the middle of the rostrum, rather stout, joints 2-7 of the funiculus

obovate, 2 a little longer than 3, the club ovate. Prothorax much longer than broad, very convex,

rounded at the sides, feebly constricted in front and strongly so behind, the short basal portion subcylin-

drical, the surface smooth. Elytra moderately long, not or very little wider than the prothorax,

subparallel to near the middle, constricted at the base, the humeri obtuse; obsoletely seriate-punctate,

the punctures sometimes traceable towards the suture and outer margin only, the setigerous impressions

more distinct. Meso- and metasternum and the sides of the abdomen with a few widely scattered

punctures. First ventral segment with two very small tubercles in the middle at the apex, and the fifth

unimpressed, in the ¢. Femora each with a short tooth. Tibie simply sinuate. Tarsal claws with a

long fine tooth.

Length 43-6, of the rostrum 23-3, breadth 12-14 millim. (¢ @.)

Hab, Panama, Bugaba (Champion).

Six specimens, the two without abdominal tubercles assumed to be females, though

not differing from the others in the length and thickness of the rostrum. This species

much resembles £. levigatus, but has the rostrum in both sexes much shorter, basally

thickened, and laterally sulcate, the claws toothed, and the first ventral segment of the

male bituberculate. LH. scolopax, Faust, from Venezuela, is also very similar, but it

has a broader and more globose prothorax, the anterior femoral tooth larger, &c.

5. Erodiscus levigatus, sp. n.

Elongate, narrow, shining, nigro-piceous, the legs and antennsw rufo-piceous; the elytral interstices 2 and 4

each with a scattered series of very long, erect, rigid, whitish sete. Head almost smooth; eyes very

narrowly separated above; rostrum about as long as the body in the 9, a little shorter and more

distinctly thickened towards the base in the ¢, longitudinally rugulose in its basal half, smoother thence

to the apex, the antenne inserted at a little beyond the middle in the ¢, and slightly before the middle

in the 9, joint 2 of the funiculus much longer than 3, the club oblong-ovate. Prothorax much longer

than broad, very convex, rounded at the sides, slightly constricted in front, the short, narrow, basal

portion subcylindrical, the base and apex somewhat coarsely punctured, the rest of the surface smooth.

Elytra moderately long, very little wider than the prothorax, subparallel to near the middle, flattened on

the disc anteriorly, abruptly constricted at the base, the humeri swollen and obtuse ; very finely seriate-

punctate, the punctures somewhat widely separated, the setigerous impressions on the interstices 2 and 4

minute. Meso- and metasternum and abdomen with a few coarse punctures at the sides. First ventral

segment transversely, and the fifth broadly and longitudinally, depressed in the middle at the apex in

the ¢, the fifth with or without a shallow depression in the 2. Anterior femora distinctly, and the two

other pairs obsoletely, toothed. Tuibic simply sinuate. First tarsal joint about as long as the others

united; tarsal claws simple.

Length 44-63, of the rostrum 37-57, breadth 14-1? millim. (¢ 2.)

ERODISCUS. 277

Four specimens. Very like E. bituberculatus, but separable from it by the simple

tarsal claws. The male from Bugaba lacks the transverse depression at the apex of

the first ventral segment. The rostrum is nearly as long as in &. longirostris, Faust.

6. Erodiscus angustatus, sp. n.

Elongate, narrow, shining, rufo-castaneous; the elytral interstices 2 and 4 each with a scattered series of

long, erect, whitish, bristly hairs. Head smooth; eyes narrowly separated; rostrum feebly curved,

slender throughout, of the same length as the elytra, finely punctured in its basal half and almost smooth

thence to the apex, the antennee inserted at the middle, joint 2 of the funiculus considerably longer

than 3. Prothorax much longer than broad, very convex, rounded at the sides, feebly constricted in

front and strongly so behind, the short basal portion subcylindrical ; sparsely punctate at the base and

apex and on the lower part of the flanks, for the rest smooth. Elytra moderately long, slightly wider

than the prothorax, subparallel in their basal third, and abruptly constricted in front, the humeri some-

what swollen; finely seriate-punctate, the punctuation becoming a little coarser near the suture, the

interstitial impressions minute. Meso- and metasternum and the abdomen with a few coarse scattered

punctures at the sides. Legs rather slender; anterior femora distinctly, and the two other pairs

obsoletely, dentate ; tibiae simply sinuate ; tarsal claws simple.

Length 34, of the rostrum 23, breadth 1 millim. (@.)

Hab. Guatemaua, Cahabon in Vera Paz (Champion).

One specimen. Smaller and narrower than EF. lwvigatus, with a relatively shorter

and more slender rostrum, the prothorax somewhat globose anteriorly, the legs not

so stout, and the general coloration castaneous. E. castaneus, Faust, from Venezuela,

and other South-American forms are similarly coloured.

Group HOPLORRHININA.

The single Tropical-American genus included in this group was referred doubtfully

by Chevrolat to the “ Antliarrhinides” of Lacordaire, the two genera of which are

African. It belongs, however, to the section ‘“Synmérides,” the anterior cox being

contiguous, a character separating Hoplorrhinus from Nanus, Schonh., of the “ 'Trype-

tides” of Lacordaire, the species of which have a somewhat similar facies and are also

Tropical-American *. The rostrum is long and slender, differently sculptured in the two

sexes, and asperate above in some of the southern forms. The antenne are elongate,

with a long basal joint to the funiculus, and the first joint of the club as long as the

others united. The prothorax is as long as or longer than broad, rounded at the sides,

without ocular lobes, and much developed beneath in front of the anterior coxe. ‘The

femora are pedunculate, strongly clavate, and toothed. The tibiz are slender and

almost straight, without claw at the apex. The tarsi are long and slender, with the

third joint strongly bilobed, and the claws long, divergent, and at most feebly angulate

towards the base (Tab. XIV. fig. 154). The species are narrow, elongate, and somewhat

depressed. H. crispus is perhaps not really congeneric with H. mexicanus ; it approaches

the genus Grasidius, which is here placed under the Erirrhina.

* The monotypic South-American genus Spheracus is compared by Faust with Hoplorrhinus ; but it has

the anterior coxe distant, and belongs to the group “ Cholina.”

Hoplorhinus, Chevrolat, Bull. Soc. Ent. Fr. 1878, p. eviii.

The two described members of this genus both inhabit Brazil, and one or two other

southern forms exist in collections. The two from our region are not very closely

allied to any of them.

widened, post-median fascia, and the suture and lateral margin thence to the base, black ; clothed with a

very fine yellowish pubescence, the elytral interstices each with a series of short, semierect, similarly-

coloured, fine, bristly hairs, these also extending over the pronotum. Head minutely punctate, the eyes

large, finely facetted, and somewhat widely separated ; rostrum (¢ ) slender, feebly curved, a little longer

Elongate, narrow, moderately shining, testaceous; sparsely clothed with a very fine, scattered, yellowish

pubescence, the upper surface with intermixed, short, curved, bristly, similarly-coloured hairs, which are

semierect on the elytra and arranged in a somewhat close series down each of the interstices. Head

finely alutaceous ; eyes large, coarsely facetted, and somewhat widely separated ; rostrum (¢) curved, a

Group BALANININA,

Balaninide, Leconte. Balaninini, Bedel.

This group is separated by Leconte from the Curculionide (=Curculionine of this

work), on account of the vertical movement of the mandibles, and it is placed by him

as a separate family near the Brenthide, though he notes the affinity of Balaninus

and Centrinus (of the Baridina). The Balaninina are poorly represented in Tropical

America, and the Palearctic and Nearctic forms of Balaninus, s. str., are very closely

allied, the various species attacking acorns, hazel-nuts, hickory-nuts, &c. |

The Central-American species, and the few specimens I have seen from the South-

American continent, all belong to Balaninus, s. str., the section Balanobius, Jekel,

being confined to the Old World. They appear to be very rare in the southern part

of our region, a single example only having been captured by myself during a long

residence in the country.

There is a single example (@) of this species in the Sallé collection, labelled as

The two males received by us from Mexico do not appreciably differ from a North-

American specimen of the same sex communicated by Mr. Wickham. JB. cary@ is very

like the European B. nucum, Linn., but has a longer and more slender rostrum, and the

suture of the elytra less prominent posteriorly, with the imbricate hairs finer and more

numerous. It is known to attack hickory-nuts.

4, Balaninus tropicalis, sp.n. (Tab. XIV. figg. 18, 18a, 2.)

Robust, piceous, the antenne and rostrum reddish, somewhat thickly clothed with coarse flavo-cinereous

pubescence, which on the elytra is mottled with brownish, the vestiture along the posterior half of the

suture ochreous, longer, denser, and imbricate, the pygidium with a dense tuft of long brownish hairs.

Head densely punctate ; rostrum slender, as long as the body, strongly curved beyond the middle, finely

punctate at the base, the antennee inserted at about three-fourths from the tip, joint 1 of the funiculus

much longer than 2, the scape as long as 1-3 united. Prothorax transverse, narrowed from the middle

forwards and constricted in front, densely punctate. Elytra broad, subcordate, flattened on the disc

anteriorly ; deeply punctate-striate, the interstices feebly convex and roughly punctulate. Femoral tooth

small, its outer edge oblique; anterior tibiee strongly mucronate at the apex; tarsal claws broadly

appendiculate..

Length 7, of the rostrum 7, breadth 34 millim. (9.)

Hab. Panama, Volcan de Chiriqui 2500 feet (Champion).

One female specimen, probably beaten from oak. Very similar to B. carye, but

with the vestiture longer and coarser, the femoral tooth smaller, its outer edge not

forming a right angle with the apex of the femur. The rostrum is greatly curved at

the apex.

Group LAMOSACCINA.

Lémosacides, Lacordaire. Lemosaccini, Leconte.

This group includes most of the exotic forms referred to Lemosaccus. The various

species are closely related to Magdalis*, from which they are widely separated by

Lacordaire.

* In the British Museum there is a Chilian species (? Lemosaccus unicolor, Blanch.) that appears to belong

to this genus,

- LAMOSACCUS. 281

LAMOSACCUS.

Lemosaccus, Schonherr, Cure. Disp. Meth. p. 50 (1826) ; Gen. Cure, iii. p. 625; op. cit. vi. 1,

p- 68 (part.) ; Lacordaire, Gen. Col. vii. p. 13; Leconte, Proc. Am. Phil. Soc. xv. p. 223.

The generic name Lemosaccus has hitherto been used to include a heterogeneous

assemblage of species which will have to be separated sooner or later (as noted long

ago by Lacordaire):—(1) Lemosaccus, s. str., confined to America, and of which

L. plagiatus (Fabr.) may be taken as the type; (2) LZ. pruinosus, Blanch., L. variegatus,

Blanch., and other Chilian and Brazilian forms*; (3) all the Australian and Malayan

forms. In JL. plagiatus and its American allies the elytra are lobed at the base on

each side of the scutellum; the rostrum is rugulose and dull in the ¢, and shining

and cylindrical in the 92, the scrobes descending to beneath the eyes; the antenne

are short, inserted near the middle of the rostrum, the club nearly or quite as long as

the funiculus; the anterior coxee are more or less widely separated; the metasternal

episterna are broad; the ventral sutures are straight; the pygidium is largely deve-

loped and fully exposed, in the ¢ divided into two segments (the upper one being the

propygidium of Lacordaire), in the @ consisting of one segment only; and the tarsal

claws are very slender. In ZL. prutnosus and its allies the elytra are not lobed in front ;

the antenne are inserted near the base of the rostrum, at least in the @; the scutellum

is elongate; the anterior coxe are contiguous; the metasternal episterna are narrow ;

the ventral sutures 2-4 are slightly curved at the sides; the pygidium is rather

narrowly exposed ; and the tarsal claws are comparatively stout. In ZL. electilis, Pasc.,

L. brevipennis, Pasc., and the numerous other Australian species I have seen, the elytra

are hollowed at the base; the antenne are inserted near the middle of the rostrum ;

the anterior cox are more or less separated; the metasternal episterna are narrow ;

the second ventral segment in both sexes is angularly produced on each side posteriorly,

almost as in Tychius and Sibinia; the pygidium is large and exposed; and the tarsal

claws are very slender. In all these insects the legs are rugose, short, and strongly

retractile; the anterior femora, at least (except in some of the Australian forms), are

toothed; and the tibie are strongly hooked at the outer apical angle, as in Magdalis.

The genus is well represented in Central America. Most of the specimens obtained

by myself were beaten from the decaying branches of trees.

Lemosaccus ruficornis, Sturm, in litt.

Lemosaccus mactatus, Jekel, in litt.

Broad, robust, black, the elytra usually with a very large, transverse, subquadrate, humeral patch rufous or

ferruginous, the greater part or the whole of the upper surface and the legs sometimes of this colour,

the antenne ferruginous; the flanks of the prothorax and under surface thickly clothed with whitish

pectinate scales, the pygidium with narrow white scales. Head alutaceous and finely punctate, shallowly

sulcate between the eyes, which are somewhat widely separated ; rostrum short and stout in both sexes,

in the g dull, rugosely punctate, and shallowly sulcate down the middle, in the cylindrical, shining,

and less coarsely punctate; antennal club as long as the funiculus. Prothorax transversely convex, as

broad as or broader than the elytra, strongly rounded at the sides, abruptly narrowed and constricted in

front, the surface coarsely, very closely, shallowly punctate. Scutellum large, depressed in the middle,

coarsely punctured in front. Elytra comparatively short, subparallel to beyond the middle, slightly

compressed at the sides below the shoulder, the latter rounded, the base strongly lobed on each side of the

scutellum ; with finely punctured, sharply-cut strie, the interstices alutaceous, asperate and angularly

raised externally, the third prominent at the base. Pygidium dull, alutaceous, and closely punctate; in

the © sharply (fig. 20), in the ¢ (fig. 19c) more feebly, carinate. Anterior femora with an obliquely

truncated tooth, the others feebly dentate. Anterior tibie short and broad in the 9, in the ¢ a little

longer and narrower, in both sexes arcuately dilated on the inner side beyond the middle, but more

broadly so in the ¢ than in the ?.

Hab. Mextco (Mus. Brit.; Sallé, ex coll. Sturm), Cordova (Sallé); Honpuras

(Sallé); Guaremana, San Gerénimo (Champion).

Found in abundance at San Gerdénimo, the specimens varying greatly in size and

colour. The dilated prothorax, with strongly rounded sides and uniform sculpture,

the sharply carinate pygidium in the female (the carina appearing angular when viewed

from the side), the dilated anterior tibie, &c., separate LZ. ruficornis at once from its

allies. ‘Two of the Mexican specimens are almost black above. |

2. Lemosaccus radiatus, sp.n. (Tab. XIV. fige. 21, 21a, 4, 2.)

oD A

Robust, moderately shining, black, the antenne and tarsi ferruginous; the depressed portions of the

upper surface clothed with scattered, ochreous, small, piliform scales, the under surface with pectinate

yellowish scales. Head alutaceous and minutely punctate, feebly foveate between the eyes and

transversely grooved behind them; the eyes large, deeply emarginate in front, and narrowly separated

above; rostrum short, cylindrical, shining, finely punctate. Prothorax broad, transversely convex,

moderately rounded at the sides, abruptly constricted and narrowed in front, sharply, interruptedly

carinate down the middle; the surface very uneven, depressed on each side of the median carina

posteriorly, the disc with irregular, sinuous, radiating, raised lines, the base, apex, and flanks coarsely,

confluently punctate. Scutellum large, cordate. Elytra moderately long, obliquely or transversely

depressed below the base, near the suture at one-third from the apex, and at the sides about the middle ;

obsoletely dentate.

Length 43-63, breadth 23-3 millim. ( 9.)

Hab. Mexico, Cordova (Sailé).

Two specimens. The emarginate eyes, the irregular radiating raised lines on the

disc of the prothorax, and the very uneven elytra readily separate this species from its

allies.

3. Leemosaccus exsculptus, sp.n. (Tab. XIV. figg. 22, 22a, 6, 2.)

Oblong, robust, slightly shining, black, the tarsi and antenne more or less piceous; the elytra with numerous

rugosely punctate, in some specimens obsoletely carinate towards the apex. Anterior femora with a

rather long, straight, truncated tooth, the intermediate and posterior femora also with a short tooth,

that on the posterior pair almost obsolete.

Length 3-4, breadth 14-2 millim. (@.)

Hab. Mexico, Cordova (Sallé); GUATEMALA, Cerro Zunil, Zapote, Capetillo

(Champion).

Seven specimens, all females, the Guatemalan examples differing from the others in

having the prothorax more uneven on the disc. The carinate, sulcate rostrum, the

unemarginate eyes, the uninterrupted prothoracic carina, the less uneven elytra, &c.,

separate this species from L. radiatus, at least in the female sex, the males of both

being unknown. .

4. Leemosaccus hamatus, sp.n. (Tab. XIV. figg. 23, 23 a, 6, 2.)

Oblong, somewhat shining ; black, the antenne, the anterior margin of the prothorax, the scutellar region,

with narrow, finely punctured striw, the interstices alutaceous, transversely wrinkled, and angularly

raised externally. Pygidium rugosely punctate, in the ? obsoletely carinate. Anterior femora with a

rather long, narrow, truncated, somewhat hooked tooth, the intermediate and hind femora feebly

dentate.

Length 23-8, breadth 13-13 millim. (¢ 2.)

Hab. Mxxico, Paso del Macho (Hége: ¢); Guaremaua, Capetillo (Champion: ¢ .)

One pair, the male having the red markings on the elytra more extended, the median

spot being developed into an angulated fascia and confluent with the apical patch.

The disc of the prothorax is sculptured as in L. exsculptus ; the anterior femoral tooth

is narrower than in that species and hooked at the tip.

5. Leemosaccus salebrosus, sp.n. (Tab. XIV. figg. 24, 24a, 5, 2.)

Lemosaccus salebrosus, Jekel, m litt.

Robust, rather dull, black, the base and apical margin of the elytra, and the prothorax in part, sometimes

strie, the interstices alutaceous, asperate and angularly raised externally, 3, 5, and 7 here and there

costate. Pygidium rugosely punctured, in the 9 distinctly, and in the ¢ obsoletely, carinate. First

ventral segment depressed in the middle in the ¢. Anterior femora with a narrow blunt tooth, the

intermediate femora with a short tooth, the hind pair obsoletely dentate.

Length 34-54, breadth 2-24 millim. (¢ 9.)

Hab. Mexico (Mus. Brit.), Juquila (Sallé); Guatemata, Tocoy (Champion) ;

Not uncommon in Mexico and Guatemala, and varying much in size (length 23-44,

breadth 14-24 millim.) and in the extent of the rufous or ferruginous humeral patch

on the elytra, this being sometimes so extended as to leave the apex only black, or

reduced (in two of the smallest females from Guatemala) to a small spot on the middle

of the disc of each. The sculpture of the prothorax is also variable, the shallow

punctures being in some examples longitudinally confluent, and in others coarser,

rounded, and separate one from another. ‘he anterior femoral tooth is short and

acute. ‘The various forms occur in the same localities, and they cannot be separated.

We figure two from Guatemala.

Length 24, breadth 14 millim. (<¢.)

Hab. Mexico, Jalapa (Hoge).

One specimen. This insect is of the same size and colour as L. hamatus, but differs

from that species in having a short acute tooth to the anterior femora, the prothorax

is more convex and very coarsely punctured, the rostrum of the male is shallowly

sulcate, and the eyes are less approximate. The prothoracic sculpture is even coarser

than in Z. sculpturatus, and the median carina sharper.

10. Lemosaccus scriptus, sp.n. (Tab. XIV. figg. 30, 304, 4, 3.)

Oblong, rather narrow, black, the elytra with a common, somewhat a-shaped, ochreous patch on the disc, the

A single (2) example, left unnamed, from Bugaba, comes very near L. exaratus.

PRIONOBRACHIUM.—CAMAROTUS. 289

Group MENEMACHINA.

Meénémachides, Lacordaire.

Faust refers a single Tropical-American genus, Prionobrachium, to this group.

It is a close ally of Chelotonyx (which, following Lacordaire, has already been dealt

with under the Ceratopina, anted, p. 126 *), both genera having the anterior coxe

somewhat widely separated, the anterior femora armed with a very large, triangular,

serrated tooth (as in Prionomerus), and the tarsal claws furnished with a long, slender

tooth (as in Anthonomus). Chelotonyx would, therefore, be better placed next

Prionobrachium, in the Menemachina.

PRIONOBRACHIUM.

Prionobrachium, Faust, Stett. ent. Zeit. 1893, p. 341.

_ The principal characters separating this genus from Chelotonyx are the shorter and

very much stouter rostrum, the more prominent ocular lobes to the prothorax, and

the shorter and broader outer joints of the funiculus, which here forms an almost.

continuous outline with the club.

Camarotides, Lacordaire.

The single known genus of this group is confined to Tropical America. All the

species are extremely rare in collections, some of them, including the two now added,

bearing an extraordinary resemblance to various Cassidide, of the genera Omoplata,

Selenis, &c. Two have been figured, one by Imhoff, the other by Karsch.

Hab. British Honpuras, Rio Sarstoon (Blancaneauz).

One specimen. This insect approaches the South-American C. cassidoides, Gyll.,

is less expanded anteriorly, the humeri being more rounded.

9. Camarotus dilatatus, sp.n. (Tab. XV. figg. 3, 3a, 0.)

Broad, depressed, shining, testaceous, the eyes, scutellum, and under surface (the head excepted) black, very

finely pubescent. Head finely punctate, the punctures becoming coarser and longitudinally confiuent on

each side of the carina between the eyes, the rostrum almost smooth at the tip, the eyes large and not

prominent; antenne a little longer than the anterior tibie. Prothorax short, nearly two and one-half

times as broad as long, abruptly narrowed and feebly constricted in front; the surface closely and rather

coarsely punctate, the flanks granulate. Elytra broadly explanate at the sides, the expanded margin

abruptly and obliquely sinuato-truncate in front and rapidly narrowing posteriorly, the humeri obtusely

angulate; the disc coarsely punctate-striate, the interstices convex and almost smooth. Anterior femoral

teeth long. Anterior tibie strongly curved, broad, sparsely ciliate within, very obliquely truncate and

sharply mucronate at the apex, the external hook moderately long. ,

Length 33, breadth 33 millim.

Hab. Guatemata, Cerro Zunil, Pacific slope, 4000 feet (Champion).

One example. More depressed than C. singularis, testaceous above and black

beneath, the explanate margin of the elytra more hollowed in front (the intermediate

legs thus being visible from above), the anterior femoral teeth longer, the anterior

tibiee very obliquely truncate at the apex and armed with a single long tooth only at

the inner angle. .

Group CHOLINA.

The species of this group are all Tropical-American and of similar habits to Hilipus

(being found about the branches of fallen timber in forest-clearings), from which they

are separable by the non-contiguous anterior cox *, the more feebly developed femoral

tooth, the less divergent tarsal claws, &c. Numerous genera have been adopted by

Lacordaire, Pascoe, and Chevrolat, but the discovery of new forms shows that several

of them cannot stand. Rhinastus and Homalonotus are not represented in the Central-

American fauna.

* Tn a new species of Hilipus, from Nicaragua, placed with Cholus when our collections were sorted, the

anterior cox are narrowly separated.

A genus including a large number of species, forty-one being known to me from

within our limits. Ina few of them the claw at or near the outer apical angle of the

tibie is absent, but no value can be placed on this character for generic separation

(as suspected by Lacordaire *), or upon the protuberant mesosternum, or the form of

the scutellum. The femora are usually dentate, but in several species the anterior

pair are unarmed, at least in the male. The specimens with a more rugose rostrum,

which is always strongly curved and rarely differs in length in the two sexes, and a

broadly, longitudinally depressed first ventral segment, are assumed to be males.

Prosternum tuberculate between the anterior coxe. Mesosternum slightly protuberant between the

intermediate cox. Metasternum and the first two ventral segments broadly depressed down the middle

and thickly pubescent in the d. Legs rather elongate ; femora each with an acute tooth

Length 15-16, breadth 53-63 millim. (3 Q.)

Hab. Nicaragua, Chontales (Belt, Janson, Richardson).

Three males and three females. The elongate shape (approaching that of Solenopus),

the comparatively short rostrum, the subcarinate, granulate, bivittate prothorax, the

rugose elytra, with small scattered patches of scales, the tuberculate prosternum, and

the thickly pubescent metasternum and first two ventral segments of the 3, sufficiently

distinguish C. tuberculifer. The structure of the prosternum is similar to that of the

species of the genus Rhinastus.

Cholus delectans, Jekel, in litt.

Hab. Mexico (Mus. Brit.), Toxpam (Sallé+); Guaremata, Cerro Zunil (Champion).

Of this species there are five specimens in our collection, three of which are from

Mexico. It is somewhat rhomboidal in shape, and thickly clothed with small, narrow,

greyish or ochreous scales, except upon the vertex ; the prothorax and elytra are

granulate, the smooth elevations being seriately arranged on the latter, the elytra with

a more or less distinct median fascia and usually a spot on the subapical callosities

sparsely squamose or almost bare. In the male the rostrum is rugose and carinate

towards the base and the first two ventral segments are broadly depressed down the

middle. The intermediate and hind femora are armed with a long tooth, that on the

anterior pair being small or almost obsolete. ‘The mesosternum is raised between the

intermediate coxe.

3. Cholus leucozona, sp.n. (Tab. XV. figg. 6, 6a, 2.)

Subelliptic, dull, nigro-piceous, the rostrum and legs rufo-piceous ; thickly clothed with minute brownish-

ochreous scales, the elytra with a deeply impressed, narrow, transverse fascia before the middle densely

clothed with white scales, and an indeterminate space before and behind this almost bare, the vestiture

of the legs and the last three ventral segments sparse and whitish. Head closely punctate, rugulose and

foveate between the eyes ; rostrum curved, stout, much longer than the prothorax, in the d rugulosely

punctate and carinate at the base, and more sparsely punctate thence to the tip, smoother in the @.

Prothorax transverse, rounded at the sides, rapidly narrowing from a little before the base, feebly

constricted in front, uniformly granulate. Scutelium closely punctured, subcordate. Elytra considerably

wider than the prothorax, subcordate, slightly constricted before the middle; seriato-granulate and also

indistinctly seriate-punctate, the interstices each with a row of slightly smaller elevations, the granules

on the anterior half here and there transverse and confluent, the narrow depressed space occupied by the

white fascia densely, minutely punctate. Mesosternum transversely raised between the coxe. Ventral

CHOLUS. 293

Hab. Guatemaua, Panzos and Chacoj in the Polochic Valley (Champion).

Two specimens. Allied to C. nigrofasciatus, from which it differs in having the

elytral fascia narrow, impressed, and densely clothed with white scales, the dark fascia

in the former being unimpressed and not interrupting the surface-sculpture.

4, Cholus alutaceus, sp.n. (Tab. XV. figg. 7, 7a, 3.)

Subelliptic, a little flattened above, black, opaque, sparsely clothed with very minute ochreous scales and

scattered, coarser, oval or piliform scales, these latter arising on the elytra from each of the punctures

and from behind each of the granular elevations. Head closely punctate and feebly foveate between the

eyes ; rostrum stout, curved, longer than the prothorax, in the ¢ rugulosely punctate, shallowly suleate,

and dull in its basal half, becoming smoother and shining towards the tip, in the 2 smoother and more

shining throughout. Prothorax transverse, rounded at the sides, much narrowed and feebly constricted

in front, alutaceous, and finely, irregularly granulate, the granulation becoming very sparse at the sides.

Scutellum subcordate, almost smooth. Elytra much wider than the prothorax, elongato-cordate,

flattened on the disc beyond the middle, the subapical callosities prominent ; seriate-punctate, the space

between each puncture obsoletely granulate, the interstices flat, alutaceous, each obsoletely seriato-

granulate from the base to the apex. Beneath alutaceous, and sparsely, very finely punctate. First and

second ventral segments broadly and feebly depressed in the middle in the ¢. Mesosternum strongly,

transversely raised between the coxe. Femora each with an acute tooth, that on the anterior pair

sometimes almost obsolete.

Length 12-15, breadth 51-63 millim. (d @.)

Hab. Guaremata, Purula and Sabo in Vera Paz (Champion).

Six specimens, all from the dense forest-region of the Atlantic slope. The dull,

alutaceous surface and the peculiar vestiture distinguish C. alutaceus at once from

C. nigrofasciatus and other allied forms.

5. Cholus levinodis, sp.n. (Tab. XV. figg. 8, 8a, 4, 3.)

Subrhomboidal, nigro-piceous or rufo-piceous, the rostrum and legs sometimes reddish ; thickly clothed with

minute, oval, brownish scales, the sides of the head and the base of the rostrum bordered with ochreous

scales, the ventral segments 3 and 4 with a broad space down the middle, and the smooth, shining

granules above and beneath, bare, the vestiture of the legs whitish or ochreous. Head closely punctate

and foveate between the eyes; rostrum curved, stout, long, in the ¢ densely, rugulosely punctate and

sulcate on either side above, and also carinate, in its basal third, and smoother beyond, in the 2 smoother

from a little before the base. Prothorax transverse, subconical, rounded at the sides posteriorly, closely

granulate, the elevations crescentiform on the disc. Scutellum subcordate. Elytra much wider than the

prothorax, subcordate, somewhat flattened on the disc, slightly constricted below the base; closely

seriato-granulate (the usual seriate punctures indistinct), the alternate interstitial series here and there

interrupted by a larger, irregular or transverse prominence. Ventral segments 3 and 4 almost smooth

along the middle, 1, 2, and 5 broadly depressed in the ¢. Mesosternum strongly, transversely raised

and sublamellate between the coxee. Femora each with an acute tooth.

Length 10-134, breadth 43-63 millim. (3 @ .)

Hab. Panama, Volcan de Chiriqui, Bugaba (Champion).

Twenty-four specimens. Separable from C. pilicauda and others by the protuberant,

lamellate mesosternum, the closely seriato-granulate elytra, the elevations on the

alternate interstices here and there large and irregular in shape, and the finer

squamosity.

294 . RHYNCHOPHORA.

6. Cholus equalis, sp.n. (Tab. XV. figg. 9, 94, 4 ¢-)

Very like C. lavinodis, but larger; the prothorax obsoletely canaliculate down the middle, the granular

elevations small and more rounded; the elytra subcaudate at the apex, seriate-punctate, the granules

smaller, sparser, and much more uniform in size, those in the striz placed between the punctures, the

subapical callosities prominent; the mesosternum less prominent between the coxe; the anterior tibiee

with a fringe of very long fulvous hairs at the apex within, and the ventral segments 1 and 2 broadly

depressed in the middle, in the ¢.

Length 14-174, breadth 64-7? millim. (d 2.)

Hab. Panama, Bugaba (Champion).

One male and two females. ‘The absence of the conspicuous larger prominences

on the elytra, which are seriate-punctate and finely granulate, the tuft of very long

fulvous hairs at the apex of the anterior tibie in the male, and the less prominent

mesosternum, readily distinguish this insect from C. levinodis. The allied C. uniformis,

Pasc., from Para, is larger, and has the elytra broader at the base and more distinctly

granulate, and the rostrum and legs stouter.

7. Cholus curialis. (Tab. XV. figg. 10, 10 a, ¢.)

Cholus curialis, Pasc. Journ. Linn. Soc., Zool. xi. p. 468 *.

Hab. Nicaragua, Chontales! (Belt, Janson, Richardson).

Recognizable by its somewhat rhomboidal shape, the close granulation of the

prothorax and the elytra, the smooth elevations on the latter being seriately arranged,

and the fine, ochreous vestiture, the prothorax with an oblique, dense line of ochreous

scales on either side of the disc anteriorly, extending on to the head and rostrum, and

the elytra with a few small, irregularly distributed, ochreous or pallid spots and an

oblique streak at the apex. On the flanks of the prothorax there is a broad band of

ochreous scales, extending to the gula and the mesosternal side-pieces, but not on to

the metasternum. The mesosternum is strongly, transversely protuberant between the

intermediate coxe.

punctured at the base, smoother towards the tip. Prothorax broader than long, subconical, granulate,

the elevations fattened and here and there confluent. Scutellum subcordate, rather convex, closely,

finely punctate. Elytra subcordate, the sides at the base forming an almost continuous outline with those

of the prothorax, the sculpture similar, but with the elevations irregularly, transversely confluent,

the seriate punctures indistinct. Beneath with scattered, small, shining, bare spots, and for the rest

densely squamose. First ventral segment feebly depressed down the middle in the d. Mesosternum

transversely convex between the cox. Legs rather long; femora each with an acute tooth.

Length 15-22, breadth 7,,-11 millim. (d ¢.-)

Hab. Costa Rica, Limon (Biolley, in Mus. Brit.); Panama, Volcan de Chiriqui

3000 to 4000 feet (Champion).

Eight specimens. This insect resembles C. vidwatus in size and shape, but differs

from it in the less rugose elytra, and in the denser vestiture of both the upper and

under surfaces, the transition in the colour of the scales being very abrupt laterally.

10. Cholus viduatus. (Tab. XV. figg. 12, 124, 3.)

Cholus viduatus, Pasc. Journ. Linn. Soc., Zool. xi. p. 469°.

Hab. Nicaragua, Chontales! (Belt, Janson, Richardson).

A large species of rhomboidal form and shining black colour, the prothorax and

elytra closely, irregularly granulate (the elevations on the latter transversely confluent),

and both with numerous, small, scattered, dense patches of white scales, the rest of

the surface with a fine whitish pubescence between the smooth prominences. The

mesosternum is strongly raised and tuberculiform between the coxe. ‘The apical

margin of the elytra is finely crenulate. The femora are each armed with an acute

tooth.

Head finely punctate, feebly foveate between the eyes; rostrum stout, curved, longer than the prothorax,

rugulosely punctate at the sides, smoother along the centre and towards the apex. Prothorax transverse,

rounded at the sides, constricted and much narrowed in front; the surface minutely punctate, granulate

at the sides, the granulation becoming flattened and almost obsolete on the disc. Scutellum subcordate,

finely punctate. Elytra wider than the prothorax, subcordate ; seriate-punctate, the interstices obsoletely

granulate on the disc, the granulation becoming more distinct towards the sides and apex, the apical

margin finely crenulate. Mesosternum convex between the coxe. First ventral segment depressed down

the middle, the depression extending along the second also in the g. Intermediate and posterior femora

each with a short tooth, the anterior pair unarmed.

Length 17-19, breadth 77-9 millim. (d 2.)

Hab. Costa Rica (Van Patten).

Three rather worn specimens, apparently including both sexes, This is a form of

the Nicaraguan C. vidwatus, from which it differs in having the prothorax and elytra

much smoother, with very few white spots, and the anterior femora without trace of

a tooth.

In the form described by Chevrolat, which occurs in Mexico and Costa Rica, the

vestiture is entirely white, and on the elytra is reduced to a median fascia, which

extends along the suture to the apex, so as to partly enclose a large, bare, rounded

space. In the var. schénherri the squamosity covers more than half the surface of

the elytra, and is brownish or ochreous in colour, becoming whitish along its ante-

rior edge and round the subapical callosities. Twenty-one specimens are contained in

our collection, of which three belong to the typical form, nine to the var. segregatus,

and nine to the var. schénherri. The males have the metasternum and first ventral

segment broadly depressed down the middle.

overlooked by Pascoe and Chevrolat. The variety differs from the type in the rather

coarser and more scattered granulation of the elytra, which also lack the condensed

submarginal vitta. Numerous specimens of C. cinctus have been seen from Nicaragua.

The typical and the varietal forms occur at the same locality in Costa Rica, an example

of the latter having been sent us under the MS. name of Archarias dionychoides,

Desbr. The subsequently described C. cinctus (Oliv.), from Cayenne, is smaller and

has a denser and more sharply defined submarginal vitta. An example from Chontales

is figured.

19. Cholus circumnotatus, sp.n. (Tab. XV. figg. 24, 24a, ¢.)

Elongate, subelliptic, flattened above, black; somewhat thickly clothed with small, narrow, ochreous scales,

the head, prothorax, and elytra with a continuous, depressed, submarginal vitta, the elytra with a small

depressed spot below the base beneath, and the under surface, densely clothed with rather broad, flattened,

whitish scales, the ventral segments with a broad space down the middle more sparsely squamose, the

legs with narrow yellowish-white scales. Head rugulosely punctate and foveate between the eyes ;

rostrum stout, moderately curved, much longer than the prothorax, carinate to near the tip, longitudinally

wrinkled to about the middle and closely punctate thence to the apex. Prothorax transverse, rapidly

upon the vitte) closely granulate. Scutellum transversely cordate. Elytra at the sides forming an almost

continuous outline with the prothorax, elongato-cordate, transversely depressed at the base; closely,

irregularly granulate and also indistinctly seriate-punctate. Beneath finely punctate and feebly granulate,

the first ventral segment depressed along the middle. Mesosternum not raised between the coxe. Legs

rather elongate ; femora each with a narrow tooth, that on the anterior pair long.

Length 14, breadth 54 millim. (¢.) .

Hab. Guatemaua, El Tumbador, Pacific slope, 2500 feet (Champion).

One specimen. Narrower than C. cinctus (Drury), the elytra at the sides forming

an almost continuous outline with the prothorax, the whitish vitta more distant from

the margin, sharply defined, and placed in a shallow groove (as in the South-American

C. albicinctus, Germ.), the granulation of the elytra more irregular, &c.

20. Cholus inzequalis, sp.n. (Tab. XV. figg. 25, 25a, 3.)

Oblong, subelliptic, flattened above, piceous or black, dull, thickly clothed above and beneath with minute

the eyes; rostrum stout, much longer than the prothorax, curved, widened at the tip, sulcate on each

side at the base above, in the ¢ rugulosely punctate, in the 2 almost smooth from the sulci to

the apex. Prothorax transverse, rounded at the sides posteriorly, rapidly narrowing from a little before

the base to the apex, slightly constricted in front; finely and somewhat closely granulate, and with

indications of a bare median line, the interspaces alutaceous. Scutellum transverse, rather large. Elytra

a little wider than the prothorax, elongato-cordate, uneven, the third interstice sometimes costate in its

median third, or the disc transversely wrinkled or irregularly depressed ; seriate-punctate and finely

granulate, the interspaces alutaceous. Beneath dull, alutaceous. Mesosternum flattened between the

coxe. First ventral segment unimpressed in the male. Femora each with a narrow tooth.

Length 13-18, breadth 53-71 millim. (¢ 9.)

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

Six specimens. More elongate than C. alutaceus, the elytra relatively narrower at

the base, uneven, and with the vestiture closer and uniform throughout, the scutellum

transverse, the mesonotum not protuberant. C. delumbis, Pasc., from Ecuador, is also

not unlike the present species, but it is broader and has the elytra still more uneven,

Length 12, breadth 6 millim. (9 ?.)

Hab. Muxico (Sallé, ea coll. Sturm).

One specimen, abraded above, apparently female (the rostrum being almost smooth),

though the abdomen is depressed at the base. Somewhat resembling the Nicaraguan

C. viduatus, but with the elytra shorter and at the sides forming an almost continuous

outline with the prothorax, the seriate punctuation much less interrupted, and the

white spots absent, the rostrum very long and comparatively slender, the mesosternum

flattened between the coxe, the hook at the outer apical angle of the tibiz short. The

elytra are much less narrowed behind than in C. mudtiguttatus, the general shape being

Length 15-16, breadth 64-63 millim. (¢ 9.)

Hab. Costa Rica, Irazu, Rio Sucio (Rogers).

In this insect the prothorax and elytra are foveolate and the fovee densely squamose,

the rest of their surface being smooth, bare, and shining, a form of sculpture foreign

to the other Central-American members of the genus. ‘Two specimens.

23. Cholus confluens, sp. n. (Tab. XVI. figg. 2, 2a, ¢.)

Subelliptic, narrow, black, shining; somewhat thickly clothed above and beneath with rather coarse, narrow,

Length 11, breadth 43 millim. (¢.)

302 RHYNCHOPHORA.

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

One specimen. ‘The coarsely, confluently granulate prothorax and elytra, the

rather coarse whitish squamosity, the transverse scutellum, the fasciate elytra, and the

narrow subelliptic general shape, sufficiently distinguish C. confiluens from the other

Central-American species of the genus.

24. Cholus insignis, sp.n. (Tab. XVI. figg. 3, 34, 6 )

Subrhomboidal, rather dull, black, the legs (the apices of the femora excepted), rostrum, and antenne rufo-

scales, the elytra with a sharply defined transverse space at the base and a rounded patch on the

subapical callosities, the last three ventral segments in great part, and the shining granular prominences,

bare; the vestiture of the legs sparse, whitish, and piliform. Head rugulosely punctate and feebly foveate

between the eyes; rostrum moderately stout, curved, in the g rugulosely punctate and carinate to

(Conradt).

Numerous specimens of the form selected as typical, all but one being from Vera

Paz, two of the var. a from Misantla, and one of the var. 8 from Mexico, without

definite locality. This is one of several nearly allied Central-American species, distin-

guishable by the sharply defined bare spaces on the elytra, the sparse granulation, and

the non-protuberant mesosternum.

denser throughout, extending even to the legs, the granular elevations flattened, and

on the elytra much more scattered and mainly confined to the interstices.

27. Cholus subcaudatus, sp.n. (Tab. XVI. figg. 6, 6a, 3.)

Rhomboidal, nigro-piceous or piceous, the rostrum and legs sometimes reddish ; thickly clothed with small,

rounded or oval, brownish or greyish scales, the last three ventral segments ( ¢ ) with a broad space down the

shoulders and rapidly narrowing thence to the apex, depressed at the base and beyond the middle, the

apices (¢ ) produced, subcaudate, and clothed with long hairs; seriate-punctate, the interstices rather

sparsely granulate, the elevations unequal in size and giving an uneven appearance to the surface. Ventral

segments 3-5 (6) smooth along the middle, 5 deeply, transversely depressed. Mesosternum not raised

between the coxe. Femora each with an acute tooth.

Length 11-12, breadth 5-53 millim. (¢.)

Hab. Mexico (Mus. Brit.); Guatemana, San Juan and Panima in Vera Paz

(Champion) ; Panama, Volcan de Chiriqui (Champion).

Five specimens, varying a little in the size of the granular elevations. Very like

C. pilicauda ; but with the elytra more uneven (appearing somewhat gibbous anteriorly,

Found in plenty on the slopes of the Volcan de Chiriqui. The chief characters of

this species are the small tuft of ochreous hairs at the apex of the elytra in the 3, the

sparse granulation, the larger elevations on the elytra being conspicuous and each

followed by a very short pallid seta, and the dense, uniform, brownish or brownish-

ochreous squamosity of the upper surface.

Cholus albiventris, Chevr. Le Nat. iii. p. 482 (1881) *.

Hab. Costa Rica! (Mus. Holm.).

The type of this species, a female, which we figure, kindly lent me by Dr. Sjdstedt,

is extremely like C. lewcogaster (of which the male only is known), but differs in its

less elongate shape, the much longer, smoother, and sharply carinate rostrum, the

more scattered, transverse granulation of the prothorax, the rounded scutellum, and

the relatively broader and shorter elytra.

Hab. Nicaracva, Chontales (Belt); Panama, Bugaba (Champion).

Two specimens. Easily recognizable amongst the Central-American Choli by its

small size, oval shape, the uniform, coarse, whitish squamosity, interrupted by numerous

bare spaces, the irregularly foveolate elytra, and the rugose rostrum and legs. It is,

however, very like an undescribed species from Ecuador * in the Pascoe collection, but

is narrower, the elytra are less rugose, and the white squamosity is differently arranged.

The following is yet another allied form.

34. Cholus nigromaculatus, sp. n. (Tab. XVI. figg. 13, 13.4, 3.)

Oval, black, densely clothed (the granular elevations excepted) with rather coarse, rounded, whitish scales ;

finely punctate. Elytra much wider than the prothorax, elongato-cordate, somewhat flattened on the

disc, the humeri subangular and laterally prominent ; sulcate, the interstices costate, shining, and very

sparsely punctate, the close punctuation of the sulci hidden by the dense squamosity. Beneath closely

punctate; first ventral segment depressed along the middle. Mesosternum flattened between the cox.

Legs rather elongate, the hind femora about yeaching the apex of the abdomen; femora each with an

acute tooth.

Length 11, breadth 43 millim. (d 9.)

Hab. Panama, Volcan de Chiriqui 8000 feet (Champion).

One specimen, obtained in the bamboo-thickets high up on the southern slope of

the Volcan de Chiriqui. The elytral sculpture resembles that of Dionychus paralle(o-

grammus, Astyage lineigera, &c., a character separating C. corrugatus from the other

Choli here described.

308 RHYNCHOPHORA.

37. Cholus aureus, sp. n. (Tab. XVI. figg. 16, 16 a—c, 3.)

Oblong, subelliptic, somewhat flattened above, piceous, the antenne and legs more or less ferruginous; above

and beneath densely clothed with coarse, flattened, oblong-oval, golden-yellow scales, the vestiture a little

sparser down the middle of the pronotum, the vertex, scutellum, and the apex of the rostrum bare ; the

femora also clothed with coarse yellow scales, the vestiture of the tibie and tarsi piliform. Head closely,

finely punctate; rostrum stout, curved, longer than the prothorax, rugulose and obsoletely carinate,

smoother at the tip; joint 1 of the funiculus nearly as long as 2-5 united. Prothorax transverse, rounded

at the sides anteriorly, and narrowing from the middle forward, closely, minutely punctate, the interspaces

on the dise here and there smooth and a little raised. Scutellum transverse. Elytra at the sides forming

an almost continuous outline with the prothorax, elongato-cordate, the subapical callosities prominent ;

closely, minutely, confusedly punctate. Mesosternum flattened between the coxe. First ventral segment

slightly depressed down the middle. Legs rather short; femora each with an acute tooth ; tibice strongly

mucronate at the inner apical angle and with a long hook at the outer angle.

Length 84, breadth 33 millim. (<¢.)

Hab. Panama, Bugaba (Champion).—Cotom1 (coll. Pascoe, in Mus. Brit.).

Two specimens, the one from Bugaba in perfectly fresh condition. More elongate

and less convex than C. cretaceus, the dense vestiture (fig. 16 ¢) almost golden in certain

lights and uninterrupted, the scutellum transverse and bare, the legs reddish and not

so stout, the tibie both mucronate and unguiculate at the apex. ‘The species in the

Pascoe collection is labelled C. sguamosus, Boh., but this is a mistake, Boheman’s

species having no visible scutellum ; the latter belongs to Lobaspis, Chevr.*

38. Cholus estriatus, sp. n. (Tab. XVI. figg. 17,17 a, 2.)

Narrow, subelliptic, nigro-eneous, shining, the antenne, rostrum, and legs in great part ferruginous; thickly

clothed above and beneath with coarse, oval, brownish-white scales, which are condensed into a broad,

oblique vitta on the outer part of the disc of each elytron; the vestiture of the legs piliform, the femora

also with long scales. Head densely punctate; rostrum rather slender, curved, much longer than the

prothorax, densely punctate and squamose at the base, for the rest bare and with widely scattered fine

punctures, the antenne inserted about the middle. Prothorax broader than long, conical, slightly rounded

at the sides behind, closely, finely punctate. Scutellum subcordate. Elytra slightly wider than the

prothorax, elongato-cordate ; shallowly, longitudinally grooved (except upon the space occupied by the

vitta), the interspaces becoming subcostate at the sides, the entire surface very finely, irregularly punctate,

without rows of coarser impressions. First ventral segment broadly depressed down the middle in the ¢.

Mesosternum flattened between the coxe. Legs elongate, rather slender; femora each with an acute

tooth ; tibia mucronate at the inner apical angle, the outer angle unarmed.

Length 73, breadth 3 millim. (¢ 9.)

Hab. Panama, Volcan de Chiriqui 8000 feet (Champion).

Two specimens, assumed to be sexes, but scarcely differing in the sculpture and

vestiture of the rostrum. The conical prothorax, the more slender rostrum and legs,

and the vittate elytra distinguish this species from both C. awreus and C. cretaceus.

The tibie are unarmed at the outer apical angle.

CHOLUS. 309

39. Cholus cretaceus, sp. n. (Tab. XVI. figg. 18, 18, a, 6, 2.)

Oval, convex, black or piceous (the surface shining and with a brassy lustre when denuded of scales), the

antenne partly ferruginous; above and beneath densely clothed with coarse, oblong-oval, depressed,

shining, whitish or brownish-white scales, with the smooth, minute, scattered asperities of the surface

here and there showing through, each elytron usually with an oblique fascia before the middle and a

triangular patch towards the apex more sparsely squamose ; the vestiture of the legs coarse and

whitish. Head densely punctate; rostrum moderately stout, curved, longer than the prothorax, rugosely

punctate and longitudinally wrinkled, a little smoother in the @. Prothorax transverse, rounded at the

sides anteriorly, and narrowed and constricted in front, densely, finely punctate, the narrow interspaces

here and there a little raised or subgranulate. Scutellum subcordate, squamose. Elytra slightly wider than

the prothorax, oblong-subcordate, transversely depressed at the base and flattened on the disc towards the

apex; seriate-punctate (the punctures often completely hidden by the vestiture), the interstices minutely

punctate and here and there asperate or subgranulate. Mesosternum flattened between the coxe. First

ventral segment depressed along the middle in the g. Legs rather short and stout; femora clavate and

each armed with an acute tooth; tibize mucronate at the inner apical angle, the outer angle with a very

minute tooth.

Length 5-8, breadth 2-4 millim. (¢ 2.)

Hab. Mexico, Toxpam (Sallé), Jalapa (Hége), Tacotalpa in Tabasco (¢a coll. Flohr),

Teapa (Hoge, H. H. Smith); Brrrisn Honpuras, Belize (Blancaneaux) ; GUATEMALA,

Cubilguitz, Cahabon, and Chiacam in Vera Paz (Champion), Coban (Conradt); Nica-

raaua, Chontales (Janson).

Found in profusion at Chiacam, and apparently a common insect also in S.E. Mexico.

C. cretaceus is nearly related to the South-American C. squamosus and C. lepidotus,

Boh. (the first-mentioned of these having the tibie unarmed at the outer apical

angle), but it has a well-developed scutellum, &c. In fresh examples the shining

vestiture is almost golden in certain lights. The elytral fascie are most distinct

in the partially abraded specimens. ‘To judge from the description, the prominent

exposed scutellum separates it from Lobaspzs argentulus, Chevr., from Colombia.

C. flavescens and C. sulphuratus, Fabr., from Brazil, are also allied forms.

40. Cholus chiriquensis, sp. n. (Tab. XVI. figg. 19, 194, 6.)

Subrhomboidal, narrow, black, the antennz in part ferruginous ; above and beneath, except upon the smooth,

scattered, shining elevations of the surface, thickly clothed with small, oval, shining, whitish or yellowish-

white scales, the vestiture of the legs coarse and piliform. Head densely, rugulosely punctate ; rostrum

rather slender, strongly curved, much longer than the prothorax, bare and very sparsely punctate from

near the base to the apex, the antenn inserted at the middle. Prothorax transverse, conical, the sides

feebly rounded posteriorly ; sparsely, rather coarsely granulate, the elevations becoming transverse on the

disc, the interspace very minutely punctate. Scutellum as broad as long. Elytra at the sides forming a

continuous outline with the prothorax, rapidly narrowing from the base, transversely depressed below the

anterior margin ; interruptedly seriate-punctate, the interstices very minutely punctate and with scattered,

smooth, irregular elevations. Anterior cox very widely separated. Mesosternum flattened between

the cox. Legs elongate; femora each with an acute tooth; tibiee feebly mucronate at the inner apical

angle, the hook at the outer angle obsolete.

Length 8-8, breadth 22-23 millim. ( 2.)

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

Two specimens, probably both females, the rostrum being almost smooth from near

the base, though the ventral segments are smoother along the middle in one of them.

Extremely like C. canescens, but with the elytra less widened at the base and with

more numerous elevations, the scutellum shorter, the rostrum smoother and not so

stout (¢), the anterior coxee more widely separated, the tibie without a long hook

near the outer apical angle, the scales on the upper and under surfaces less rounded.

41. Cholus fusiformis, sp.n. (Tab. XVI. figg. 20, 20a, 0, 3.)

Elongate, narrow, somewhat fusiform, black, shining; here and there densely clothed with patches of long

piliform, ochreous scales, which tend to form two vitte on the head, these becoming united in front and

extending along the rostrum, an interrupted vitta on each side of the disc of the prothorax, and two

oblique vitte on the posterior half of the elytra and some scattered spots towards their base, the vestiture

beneath mainly concentrated at the sides and along the middle. Head densely, rugulosely punctate ;

rostrum about as long as the prothorax, stout, abruptly declivous above from opposite the points of

insertion of the antennsw, widened towards the base and apex, shallowly sulcate, and densely, rugulosely

punctate to about the middle, and very sparsely punctate thence to the tip, obsoletely carinate at the base

only, the lower surface quite smooth; antennal club nearly as long as joints 2-7 of the funiculus united.

Prothorax a little broader than long, subconical, the sides slightly rounded at the middle, the ocular lobes

distinct ; closely, minutely punctate and feebly granulate, the disc with an almost obsolete median channel,

which becomes wider and deeper at the base, and also grooved laterally. Scutellum rounded. LElytra

considerably wider than the prothorax, elongato-cordate, the scutellar region depressed, the basal margin

raised; rather coarsely seriate-punctate, the interstices very minutely punctate. Beneath closely, very

finely punctate ; the first two ventral segments deeply excavate down the middle. Anterior coxe rather

narrowly separated. Mesosternum flattened between the coxe. Legs long; femora each with an acute

tooth ; tibie shortly and bluntly mucronate at the inner apical angle, the outer angle unarmed.

Length 14, breadth 5 millim. (¢.)

Hab. Costa Rica, Rio Sucio (Rogers).

One specimen, somewhat abraded above. An aberrant form that may have to be

separated from Cholus. The tooth at the inner apical angle of the tibie is short and

blunt, and the hook at the outer angle is absent. The antennal club is long, and the

rostrum is peculiarly shaped.

ERETHISTES.

Erethistes, Pascoe, Journ. Linn. Soc., Zool. xi. p. 471 (1878).

The species referred to this genus agree with Peridereus, Schonh., and Kangoropus,

Chevr.*, in having the posterior femora extending beyond the apex of the abdomen ft.

They have the ocular lobes of the prothorax obsolete or feebly developed, and the

tibiz either furnished with a short claw or unarmed at the outer apical angle. It is

doubtful if Erethistes can be maintained as distinct from Periderewus, the armature

of the tibie, as in Cholus, varying in development according to the species. The

characters of Kangoropus (in which Chevrolat includes Sclerosomus granulosus, Fahr.)

are not very obvious from the description.

* Bull. Soc. Ent. Fr. 1878, p. exxvi.

+ This character is not shown in our figures, owing to the foreshortening of the legs.

ERETHISTES. | 311

$1. Tibia feedly unguiculate at the outer apical angle.

1. Erethistes cyanipes, sp.n. (Tab. XVI. figg. 21, 21a, 6, 2.)

Subrhomboidal, robust, black, with an sneous or bluish lustre, this being particularly noticeable on the legs ;

above and beneath with the spaces between the smooth elevations thickly clothed with small, oval or

oblong-oval, whitish or brownish-white scales (which give a mottled appearance to the surface), the

ventral segments similarly clothed, the vestiture of the legs piliform. Head closely, rugulosely punctate ;

rostrum moderately curved, rather stout, longer than the prothorax, carinate and closely punctate at the

base, almost smooth in its outer half, the antenne inserted at the middle. Prothorax broader than long,

somewhat rounded at the sides, narrowing from a little before the base, feebly constricted in front, closely,

rather coarsely granulate, with indications of a short ocular lobe. Scutellum oval. Elytra very little

wider than the prothorax, oblong-cordate; seriate-punctate, the interstices with smooth, transverse,

irregular elevations or granules separating the squamigerous depressions, which are here and there

transversely confluent. Anterior and intermediate cox very widely separated, the mesosternum

flattened between the coxe. Prosternum emarginate in front. Legs elongate, stout; femora each

with an acute tooth, the hind pair reaching some distance beyond the apex of the abdomen ; tibise

mucronate at the inner apical angle and with a short claw at the outer angle.

Length 16-18, breadth 73-81 millim. ( 2.)

Hab. Mexico, Ventanas in Durango (Hége); Nicaracua, Chontales (Janson).

Two specimens, probably both of the female sex, differing inter se in the sculpture and

vestiture of the elytra, the Mexican insect (which we figure) having the smooth spaces

smaller and granuliform, and the squamosity longer and more abundant. LH. cyanipes

may be known from Cholus cinctus and its allies by the elongate hind femora.

§ 2. Tibicee unarmed at the outer apical angle.

9. Erethistes triangularis, sp. n. (Tab. XVI. figg. 22, 22a, 6.)

Rhomboidal, flattened above, black, shining ; clothed with small, scattered patches of coarse, oval, yellowish

scales, those on the elytra placed in the larger depressions of the surface and seriately arranged, the

under surface a little more densely squamose, except along a broad space down the middle of the ventral

segments 2-5, the legs with white hairs, the femora also wth yellowish scales. Head densely, rugosely

punctate, the eyes very large and prominent; rostrum reaching the anterior margin of the metasternum,

moderately stout, curved, rugulosely punctate and carinate at the base, for the rest very sparsely punctured,

the antenne inserted at the middle. Prothorax broader than long, subconical, constricted in front, rather

coarsely granulate, the elevations becoming more crowded and transverse on the disc. Scutellum rounded.

Elytra much wider than the prothorax, rapidly narrowing from the base, somewhat triangular, the humeri

being laterally prominent, transversely depressed below the anterior margin, the apices obtuse; inter-

ruptedly seriate-punctate, the alternate interstices with a series of subquadrate or rounded, and the others

with a series of smaller, fovese, which are here and there transversely confluent, 7 and 9 subcostate.

Anterior cox widely separated. Ventral segments with a broad, smooth, sparsely squamose space down

the middle, 1 broadly depressed in the centre behind. Legs elongate; femora each with an acute tooth,

the hind pair reaching a little beyond the apex of the abdomen ; tibise unarmed at the outer apical angle.

Length 12, breadth 53 millim.

Hab. Costa Rica, Rio Sucio (Rogers).

One specimen, probably a male. The flattened, subtriangular, seriate-punctate and

foveolate elytra, and the small, scattered, dense patches of coarse yellowish scales, which

cover the larger depressions of their surface, distinguish this species at once from

its allies.

312 RHYNCHOPHORA.

8 Erethistes lineatocollis, sp.n. (Tab. XVI. figg. 23, 23a, ¢.)

Elliptic, black, shining, the antenne ferruginous at the base ; clothed above with scattered, coarse, oval, whitish

scales, which are condensed into a line along the inner margin of each of the eyes, three narrow vitts on

the prothorax, and numerous irregular patches on the elytra, the larger markings on the latter arranged

in an interrupted longitudinal series near the suture and a broader one on the outer part of the disc; the

under surface densely clothed with similar, yellowish-white scales, the vestiture of the legs sparser and

piliform. Head sparsely punctate, narrowly sulcate between the eyes, which are large and rather

prominent; rostrum moderately stout, about as long as the prothorax, curved, depressed at the base

above, and somewhat abruptly declivous towards the apex, almost smooth, the antennz inserted a little

before the middle, joint 2 of the funiculus nearly twice as long as 3. Prothorax broader than long,

subconical, feebly rounded at the sides, slightly constricted in front, the spaces between the vittz almost

smooth. Scutellum scutiform. Elytra considerably wider than the prothorax, elongato-cordate, trans-

versely depressed at the base; shallowly seriate-punctate and obsoletely foveolate, the interspaces

between the scattered patches of scales smooth. Anterior cox narrowly separated; mesosternum

flattened and rather narrow between the cox. Ventral segments 1 and 2 broadly flattened down the

middle. Legs moderately elongate; femora each with an acute tooth, the posterior pair extending a

little beyond the apex of the abdomen; tibiz nnarmed at the outer apical angle.

Length 114, breadth 43 millim. (d¢.)

Hab. Nicaracua, Chontales (Janson).

One specimen. The comparatively short, almost smooth, basally depressed rostrum,

the trivittate prothorax, the mottled, elongato-cordate elytra, the shining, almost smooth,

bare interspaces of the upper surface, and the coarse, whitish squamosity, render this

species easily recognizable. The rostrum is shaped very much as in Cholus fusiformis.

4. Erethistes zygopoides, sp. n. (Tab. XVI. figg. 24, 24 a, b.)

Elongate, narrow, widened anteriorly, flattened above and convex beneath, piceous, the rostrum, antenne, and

legs reddish; the upper surface, except upon the small, smooth, shining granules, somewhat thickly

clothed with minute, narrow, ochreous scales ; the under surface sparsely clothed with similarly coloured,

coarser scales, which are condensed into patches on the side-pieces of the meso- and metasternum ; the

legs sparsely clothed with short, whitish hairs, Head convex, granulate and closely punctate, the eyes

comparatively small and very widely separated; rostrum moderately stout, long, curved, bare and very

sparsely punctate throughout, the antenne inserted at the middle. Prothorax nearly as long as broad,

emarginate in front, rapidly narrowing from the middle forwards, and also slightly narrowed behind,

subcordate. Elytra twice the length of the prothorax, and slightly wider than it at the base, obconic,

subtruncate in front, conjointly rounded at the apex; the disc seriato-granulate and indistinctly seriate-

punctate, the granulation becoming obsolete at the sides, where the punctures are large and foveiform.

Ventral segments ascending, 1 granulate in the middle. Anterior cox moderately distant. Mesosternum

not raised between the coxe. Legs elongate; femora almost linear, each armed with a narrow, acute

tooth, the hind pair reaching a little beyond the apex of the abdomen; tibie unarmed at the outer

. apical angle.

Length 124, breadth 43 millim. (? 9.)

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

One specimen. This curious species approaches the Brazilian EF. tetricus (Fahr.) ;

1. Sclerosomus laticauda, sp. n. (Tab. XVI. figg. 26, 26 a.)

Broad, oval, black, the antenne (the club excepted) ferruginous, opaque, the minute granules shining ; some-

what thickly clothed with small, oval, brownish-ochreous scales, the prothorax with a faint oblique line

on each side of the disc and a minute spot on the flanks, and the elytra with a narrow transverse fascia

on the outer part of the disc at about the middle, two minute spots at the base (one near the scutellum

and the other at the shoulder) and another near the apex, white; the vestiture of the under surface a little

coarser, that of the legs sparse. Head rugosely punctate and granulate, the eyes very widely separated ;

rostrum exceedingly stout, strongly curved, longer than the prothorax, rugosely punctate and subcarinate,

almost smooth at the tip, the antenn inserted far before the middle. Prothorax strongly transverse,

rounded at the sides, sinuate at the apex, narrowing from the middle forwards and also a little narrowed

behind, and slightly constricted in front, closely, finely granulate. Scutellum transverse. Elytra con-

siderably wider than, and about two and one-fourth times the length of, the prothorax, truncate at the

base, broadly flattened along the suture anteriorly, parallel in their basal third and rapidly narrowing

thence to the apex, the apices broadly, separately caudate ; somewhat closely, finely granulate, the seriate

punctures scarcely visible. Prosternum emarginate in front. Anterior coxe rather narrowly separated.

AMERICA, Cayenne ! 235-8, |

We have received seven specimens only of this insect from within our limits, and it

is very probable that Schénherr’s Mexican record refers to the following species. The

unarmed anterior femora, the sparsely, but distinctly punctured prothorax, and the

coarsely punctured first ventral segment are the chief characters of C. rubetra.

The ninth elytral stria is placed in a deep groove, as in C. armatus, the eighth also

being sulcate in several of the South-American forms.

2. Cleogonus armatus, sp.n. (Tab. XVII. figg. 1, 1a, 4, 3 *.)

Black, shining, the antennse obscure ferruginous ; glabrous above, the under surface and legs with scattered,

minute, hair-like, whitish scales, the meso- and metasternum densely clothed with fulvous pubescence

along the middle. Head sparsely, minutely punctate, the eyesvery narrowly separated, the rostrum some-

what coarsely punctured. Prothorax subconical, very minutely, rather closely punctate. Elytra finely

and shallowly punctate-striate, with the interstices very minutely punctate, the ninth row of punctures

placed in a deep sulcus throughout, and the short tenth row also in a rather deep groove. Metasternum

with a few coarse, deep, scattered punctures at the sides. Ventral segments 2-4 very finely, and 1 and

5 more coarsely punctate, the fifth transversely depressed in the middle behind in the g¢. Anterior

femora armed with a sharp triangular tooth on the inner lower edge, and the others obsoletely dentate

on the outer edge, at about the middle.

A common insect in Central America, and sent in abundance from Chiapas. The

toothed anterior femora, the more closely punctured prothorax, and the finely punc-

eighth elytral stria from C. columbianus, Chevr.7, the latter also having the anterior

femora sharply dentate. C. nucula, Boh., has a more coarsely punctured prothorax ;

An American genus ranging from the Southern United States to Brazil. It is easily

distinguished from Rhyssomatus by the tarsal claws being simple, and subconnate at

the base. Most of the species are brilliantly metallic. In C. crassipes the rostral

canal is long, broad, and deep, extending to the metasternum. ‘The peculiar armature

of the head of the female in two of the known forms has not previously been noticed.

Some of the species, as already noted (antea, p. 113), bear a superficial resemblance

to the smaller Sternechi (Tylomus). The Central-American representatives may be

identified by the following table :—

a. Rostral canal short, not extending beyond the prosternum ; body more or

less metallic, except in C. longirostris.

Hab. Mexico ! (Sallé), Vera Cruz (Hoge), Temax in N. Yucatan (Gaumer) ; Bririse

Honpuras, Rio Hondo (Llancaneaux).

This insect is eneous or cupreo-eeneous in colour, with the prothorax very coarsely,

longitudinally strigose; the elytra with rows of coarse, deep punctures, which are

separated by unequal distances from each other, the interstices flat, the humeri denti-

form, and the surface clothed with small scattered patches of whitish pubescence.

518 RHYNCHOPHORA.

The mesosternum is depressed between the coxe. The type has been communicated

by Dr. Heller.

9. Chalcodermus collaris.

Chalcodermus collaris, Horn, Proc. Am. Phil. Soc. xiii. p. 467 (1873) °.

Hab. Norra America, New Jersey, Texas !.—MeExico, Vera Cruz (Sal/é).

The three specimens from Vera Cruz referred to this species are inseparable from

an insect from New Jersey sent me by Mr. Wickham under the name of C. collaris,

Horn, the type of which was from Texas. Dr. Horn, however, in his brief descrip-

tion, says nothing about the obliquely truncated, subangular humeri of the elytra.

Compared with the very closely allied C. dentiferus, Faust, it has the prothorax rather

less coarsely longitudinally strigose, and the elytra rufescent, with the humeri less

acutely dilated and the coarse seriate punctures placed closer together. The meso-

sternum is depressed between the coxe.

8. Chalcodermus nigrozneus, sp. n.

Suboval, slightly shining, nigro-sneous, the legs with a cupreous lustre ; clothed with scattered, small, hair-

like, whitish scales. Head rugulosely punctate, the eyes well separated ; rostrum curved, moderately

stout, about as long as the head and prothorax, seriate-punctate in its basal two-thirds, sparsely punctate

at the tip, the antenne inserted before the middle. Prothorax transverse, rounded at the sides, abruptly

narrowed and constricted in front and slightly narrowed behind, the base strongly bisinuate, the hind

angles rather obtuse; coarsely, closely punctate, the punctures here and there confluent and on the

anterior part of the disc separated by longitudinal rug, the disc with an almost obsolete median carina

in front. Elytra much wider than the prothorax, gradually narrowing from the dentiform, laterally

projecting humeri; coarsely seriate-punctate, the interstices flat and very minutely punctate (closely

rugulose in one specimen). Mesosternum depressed between the cox. Legs stout; femora rugosely |

punctate, unidentate; tibise punctato-sulcate, each subangularly dilated at or before the middle within

and serrulate thence to the apex.

Length 4-42, breadth (excl. tooth) 2,,-23 millim. (d.)

Hab. Mexico, Teapa (H. H. Smith); Guatemata, San Gerénimo (Champion).

Two specimens. This is a form of C. dentiferus with the prothorax closely punctate,

and the longitudinal ruge not so coarse and mainly confined to the anterior part of

the disc. In the example from Guatemala the elytral interstices are closely rugulose

throughout. Ina series of C. dentiferus from Yucatan there is nothing intermediate.

4, Chalcodermus cupreipes, sp. n.

Very like C. nigroeneus, but cupreo-eneous in colour, the antenne ferruginous; the prothorax with the

sides parallel at the base and rounded and a little dilated at the middle, the hind angles rectangular, the

sculpture somewhat similar, except that the ruge between the punctures are oblique, instead of longi-

tudinal; the elytra, legs, &c., as in C, nigrowneus and C. dentiferus.

Length 43, breadth (excl. tooth) 23 millim. ( 9.)

Hab. Mexico, Tapachula in Chiapas, Pacific slope (Hége).

One specimen. Perhaps an extreme form of C. dentiferus ?

CHALCODERMUS. 319

5. Chalcodermus angularis, sp.n. (Tab. XVII. figg. 3, 3a, ¢.)

Oval, shining, seneous, the elytra often rufo-piceous, with indeterminate darker markings, the antenne

usually in part ferruginous; the elytra, legs, and under surface with scattered, rather coarse, whitish

seales. Head closely, rugosely punctate, feebly foveate between the eyes, which are well-separated ;

rostrum (¢) moderately stout, curved, about as long as the head and prothorax, sparsely punctate, the

punctures seriately arranged in its basal half, (2) smoother throughout, the antenne inserted at the

middle in the @ and much nearer the tip in the §. Prothorax transverse, parallel at the sides behind,

and narrowed and constricted in front, the base strongly bisinuate; coarsely, closely punctate, the

punctures towards the sides and apex here and there confluent and separated by oblique rugs, the disc

with a more or less distinct, very narrow, smooth space down the middle limited on each side by an

irregular row of punctures. Elytra much wider than the prothorax, gradually narrowing from the

dentiform, laterally projecting humeri; very coarsely seriate-punctate, the interstices almost flat and

faintly rugulose, each with a row of very minute punctures. Mesosternum depressed between the coxe.

Metasternum transversely thickened and lamellate in front of each of the posterior cox, appearing sharply

toothed when the insect is viewed laterally. Legs stout; femora rugosely punctate; tibia each with a

short tooth at or before the middle and serrate thence to the sharply mucronate inner apical angle.

Length 32-43, breadth 2-24 millim. (¢ 2.)

Hab. Panama, Volcan de Chiriqui, Boquete, Caldera (Champion).

Not uncommon on the slopes of the Volcan de Chiriqui. Very like C. humeridens,

Faust, from Venezuela, the type (¢) of which I have seen; but smaller and more

shining, the punctuation of the prothorax closer, the punctures on the elytra less

rounded and more irregularly placed, the interstices not so flat, the vestiture coarser.

in Vera Cruz (Sallé), Jalapa (Hoge), Teapa (H. H. Smith); Brivisn Honpvras, Rio

Hondo, Rio Sarstoon (Blancaneaux); GuaTemaLa, Chiacam and San Geronimo in Vera

Paz (Champion).

In this species the prothorax is sometimes subquadrate and toothed or angulate at

the sides anteriorly, and the very coarse punctuation is often absent from a space

on each side of the disc, as well as along the middle; the seriate punctuation of

the elytra is very coarse; and the femoral tooth is rather long, narrow, and blunt

at the tip. Out of twenty-two specimens before me, nine (including three from

North America) have the head bituberculate between the eyes (a character not

mentioned by Boheman or Horn), and on dissection they prove to be females. The

sexes of C. angulicollis differ in a similar way.

compressed, conical tubercles between the eyes in front in the 2, the latter very narrowly separated

above; rostrum moderately stout, feebly curved, about as long as the head and prothorax, punctato-

sulcate in its basal half, and sparsely punctate thence to the tip, the antennee inserted a little before the

middle. Prothorax transversely subquadrate, abruptly narrowed and constricted in front, strongly

bisinuate at the base, the sides angularly dilated at the middle inferiorly (appearing bisinuate when

viewed from above); sparsely, finely punctate, except along the smooth space down the centre, the

punctuation becoming much coarser at the sides. Elytra much wider than, and about two and one-half

times as long as, the prothorax, dilated at the sides below the humeri, which are obliquely truncated

in front; very coarsely seriate-punctate, the interstices somewhat uneven and each very minutely

uni- or biseriate punctate. Legs stout ; femora rugosely punctate and strongly dentate; tibiee punctato-

sulcate, angularly dilated on the inner side a little before the middle, and serrulate thence to the apex.

Length 43-54, breadth 23-3 millim. (¢ 2.)

Hab. Mexico (Sallé, H. H. Smith); Guaremaua, San Isidro (Champion); Panama,

Bugaba (Champion).—-VENEZUELA?; GUIANA; Braziu!.

Very like C. e@neus, but with the prothorax bisinuate at the sides, and the disc

finely punctate. Four specimens, agreeing with others from Cayenne and Brazil in

the British Museum. The tubercles on the head were not noticed by Fahreeus, but he

may not have seen both sexes.

as the prothorax, seriato-punctate, feebly carinate, and dull in its basal half, and sparsely punctate and

shining thence to the tip, (2) sparsely punctate throughout and more shining, the antenne inserted far

before the middle in both sexes. Prothorax transverse, rounded at the sides anteriorly, constricted and

narrowed in front, and bisinuate at the base; the disc coarsely, obliquely strigose and also punctate,

without distinct median carina, the flanks with very coarse punctures. Elytra subtriangular, much

wider than the prothorax, the humeri rounded externally ; punctato-sulcate, the punctures coarse and

subquadrate at the base, becoming smaller, shallower, and more scattered towards the apex, the inter-

stices move or less convex (3, 5, and 7 usually a little more raised than the others), transversely rugulose

at the base, all smoother and strongly costate on the apical declivity. Legs stout; femora closely

punctate ; tibie punctato-sulcate, the intermediate pair with a sharp triangular tooth, and the anterior

and posterior pairs angularly dilated, on the inner side about the middle, and all more or less serrulate

thence to the acutely toothed apical angle. |

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

One specimen. In this insect the legs are very stout; the tibia are so deeply

sulcate that the intervening spaces appear to be sharply carinate, and they are also

very distinctly serrate within, the intermediate pair being armed with a sharp median

the head and prothorax, finely punctate, the punctures seriate in its basal half, ( 2 ) longer, more slender,

and almost smooth. Prothorax a little broader than long, rounded at the sides anteriorly, constricted

and narrowed in front, and strongly bisinuate at the base; densely, obliquely strigose, and sometimes .

with an abbreviated median carina. Elytra much wider than the prothorax, somewhat triangular, the

humeri rounded ; coarsely seriate-punctate, the interstices rugulosely punctulate, and all sharply costate

throughout. Legs stout; femora rugosely punctate, sharply dentate; tibia punctato-sulcate, each

angularly or subangularly dilated at or before the middle within.

We have received eight specimens of this species, which is incorrectly named

C. pruinosus, Boh., in the British Museum. It is easily separable from all its allies

by the comparatively coarse vestiture, the densely strigose pronotum, and the sharply

costate elytral interstices. The squamosity of the elytra is arranged in irregular

transverse fascie.

Apparently the commonest species of the genus within our limits, the variety being

connected by intermediate forms. It is recognizable by its shining black surface and

very coarse sculpture, the prothorax coarsely strigose, the rugee becoming longitudinal

on the anterior part of the disc. ‘The elytra are subtriangular, closely seriato-foveolate,

with the humeri obliquely truncated in front. The anterior and intermediate cox

are narrowly separated.

Easily distinguishable by its elongate-triangular, coarsely seriate-punctate elytra, and

closely, obliquely strigose prothorax. The tibie are sinuate and serrate within, except

at the base, and strongly mucronate at the inner apical angle. The first ventral

segment is depressed down the middle in the male. The specimen from Nicaragua in

the British Museum is labelled C. aurichalceus, Schmidt.

Broad-oval, convex, moderately shining, black, sparsely clothed with small, hair-like, whitish scales. Head

closely, rugulosely punctate, the eyes large, coarsely facetted, and almost contiguous above and beneath ;

rostrum feebly curved, rather stout, about as long as the head and prothorax, rather sparsely punctate,

the antenne inserted at about the middle. Prothorax transverse, feebly constricted in front, parallel

Two specimens. This insect agrees perfectly in general structure with the typical

members of the genus, except that the rostral canal is deeper and broader, and extends

to the metasternum. C. spinifer, Boh., is probably an allied species, and I have seen

other unnamed somewhat similar forms in the British Museum, one from Colombia

being very like C. crassipes.

A genus confined to the New World, and including numerous very closely allied

forms, mainly separable by the sculpture of the prothorax and elytra. The tarsal

claws are cleft or toothed, and sometimes subapproximate at the base. The inter-

mediate and posterior tibie are usually sharply toothed or angulate on the outer edge

towards the apex, but in a few species the outer margin is straight.

Oblong, moderately shining, piceous, very sparsely and finely pubescent. Head densely, rugulosely punctate,

the eyes separated by a space equalling nearly half the width of the rostrum; the latter exceedingly

stout, slightly longer than the prothorax, feebly curved, densely, rugosely punctate, and carinate down

the centre, the antenna inserted far before the middle. Prothorax transverse, slightly rounded at the

sides, narrowing from the base, which is strongly bisinuate, not constricted in front ; closely, shallowly,

obliquely strigose, and with indications of a smooth median line. Elytra wider than the prothorax,

subparallel in their basal half, strongly sinuate at the base, the humeri not prominent laterally ; punctato-

sulcate, the punctures distant one from another, the interstices almost flat and densely rugose throughout.

Anterior cox narrowly separated. Legs stout; tibize widened internally from about the middle to the

tip, the intermediate and posterior pairs angulate on their outer edge and ciliate thence to the apex.

Length 63, breadth 375 millim. (¢.)

328 RHYNCHOPHORA.

Hab. Guatemata, Teleman in the Polochic Valley (Champion).

One specimen. Differs from all the allied species in its oblong general shape, the

strongly bisinuate base of the prothorax, and the densely rugose, punctato-sulcate

elytra, the interstices of which are not in the least costate. In general facies,

R. rugosus is very like a Lemosaccus. There is a somewhat similar unnamed South-

American form in the British Museum.

2. Rhyssomatus rugulipennis, sp.n. (Tab. XVII. figg. 15, 10a, 3.)

Oblong-oval, dull, black or piceous, antenne, and sometimes the rostrum, legs, and elytral coste, obscure

ferruginous, finely and rather closely pubescent. Head densely, rugulosely punctate, the eyes rather

narrowly separated ; rostrum (¢ ) stout, feebly curved, a little longer than the prothorax, carinate, and

densely, rugulosely punctate, (2) longer and much smoother, the antenne inserted at the middle in the

@ and nearer the apex in the ¢. Prothorax at the base twice as broad as long, rounded at the sides

and constricted in front; closely, longitudinally strigose, and finely carinate down the centre. Elytra

wider than the prothorax, subparallel towards the base, the humeri not prominent ; punctate-striate, the

punctures coarse and oblong in shape, the interstices closely rugulose, 3, 5, 7, 9 costate throughout and

8 costate at the base, the others flat. Beneath closely punctate. Legs short, moderately stout ;

intermediate and posterior tibie: sharply angulate externally and ciliate thence to the apex.

Length 5;-63, breadth 38-32 millim. (d ¢.)

Hab. Mexico, Durango city (Hége), Sierra de Durango (ex Flohr).

Near the North-American R. lineaticollis (Say), but more pubescent, the elytra

parallel-sided towards the base, closely rugulose, and with the coarse seriate punctures

placed in rather deep striae. Many specimens.

8. Rhyssomatus yucatanus, sp. n.

Oval, shining, nigro-piceous, the antenne and legs (the anterior femora excepted) obscure ferruginous, very

sparsely and finely pubescent. Head densely, rugulosely punctate, the eyes contiguous; rostrum

moderately stout, feebly curved, a little longer than the head and prothorax, sparsely, finely punctate,

subcarinate at the base, the antenne inserted at the middle. Prothorax at the base rather more than

twice as broad as long, narrowing forwards and abruptly constricted in front, the base feebly trisinuate ;

coarsely, longitudinally strigose on the disc and with a smooth, raised, median line, the strige becoming

oblique towards the sides. Elytra rather short, somewhat triangular, a little wider than the prothorax ;

seriato-foveolate and sparsely, feebly granulate, the interstices 3, 5, 7, 9 sharply costate, and 8 and 10

costate at the base, the suture also raised. Mesosternum slightly protuberant in front. Legs short ;

intermediate and posterior tibie sharply angulate externally and ciliate thence to the apex.

Length 44, breadth 2? millim. (2.)

Hab. Mexico, Temax in N. Yucatan (Gaumer).

One specimen. This insect has the prothorax formed as in R. Jaticollis, except that

the disc is coarsely, longitudinally strigose; the elytra, however, are relatively narrower

and distinctly granulate, and the foveee are smaller; and the rostrum is longer and

more slender. In the sculpture of the prothorax it approaches Rk. rugulipennis and

R. lineaticollis.

RHYSSOMATUS. 329

4. Rhyssomatus dilaticollis, sp.n. (Tab. XVII. figg. 16, 16a, 3.)

Oblong-oval, rather broad, moderately shining, black, the antenne and tarsi obscure ferruginous; almost

glabrous, the legs finely pubescent. Head densely, rugulosely punctate, the eyes contiguous; rostrum

very stout, curved, a little longer than the prothorax, closely, rugulosely punctate, feebly carinate in its

basal half, the antenne inserted before the middle. Prothorax strongly transverse, tuberculate on each

side inferiorly at about the middle and with the sides subparallel thence to the base, abruptly and deeply

constricted in front ; rather coarsely, obliquely strigose and also punctate, except along a narrow smooth

space in the centre. LElytra much wider than the prothorax, somewhat dilated at the sides inferiorly at

about one-fourth from the base, which is sharply raised ; coarsely seriate-punctate, the punctures placed

in shallow strie, the interstices smooth, 3, 5, 7, 9 sharply costate throughout, and 10 costate at the base.

Mesosternum protuberant in front. Legs stout; tibia strongly sinuate within, the intermediate and

posterior pairs sharply angulate externally and ciliate thence to the apex.

Length 53, breadth 3 millim. (¢.)

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

One specimen. The mesially tuberculate sides of the prothorax, the short, very stout

rostrum, and the coarsely seriate-punctate elytra, with sharply costate alternate interstices,

sufficiently distinguish &. dilaticollis from all others of the genus here enumerated.

5. Rhyssomatus acutecostatus, sp.n. (Tab. XVII. figg. 17,174, 3.)

Subrhomboidal, shining, black or nigro-piceous, the antenne and tarsi, and sometimes the elytral coste also,

more or less ferruginous, very sparsely pubescent. Head densely, rugosely punctate, the eyes somewhat

narrowly separated ; rostrum very stout, moderately curved, not longer than the head and prothorax,

closely punctate, pluri-carinate in its basal half, the antennze inserted far before the middle. Prothorax

at the base about twice as broad as long, conical, constricted in front, feebly bisinuate at the base, densely

punctate, the punctures (especially on the anterior part of the disc and at the sides) separated by narrow,

raised, oblique lines, the disc sharply carinate down the middle. Elytra much broader than the prothorax,

oblongo-cordate, the obtuse, prominent humeri forming an almost continuous outline with the sides of the

prothorax anteriorly ; seriato-foveolate, the foveze placed upon very shallow striz, the interstices 3, 5, 7,9

from the base to the apex, 8 and 10 at the base, and the suture also, sharply costate, the other interstices

flat and almost smooth. Beneath sparsely punctate. Legs stout; intermediate and posterior tibie

sharply angulate externally and ciliate thence to the apex.

Length 62-73, breadth 34-43 millim. (¢.)

Hab. Mexico, Toxpam, Orizaba (Sallé), Teapa (H. H. Smith), Tapachula (Hoge);

GuatEeMaLA, Las Mercedes, Cerro Zunil, and Zapote, Pacific slope (Champion).

Ten specimens, perhaps all males. The sharply and completely costate alternate

elytral interstices, the less approximate eyes, and the relatively shorter and stouter

rostrum separate this species at once from #&. subcostatus. It is evidently a near ally

of the Brazilian R. novalis (Germ.), but the general shape is probably more oblong.

6. Rhyssomatus crenatus, sp. n.

Subrhomboidal, shining, black, more or less mottled with rufo-piceous, the tarsi and antenne ferruginous,

sparsely pubescent. Head densely, rugulosely punctate, the eyes contiguous; rostrum (¢ ) moderately

stout, curved, much longer than the head and prothorax, closely punctate, pluri-carinate in its basal half,

(¢) a little longer, almost straight, and smoother towards the apex, the antenne inserted considerably

before the middle in the ¢, and at the middle in the 9. Prothorax much broader than long, conical,

constricted in front, strongly bisinuate at the base, the basal margin raised; closely, obliquely strigose

and closely, finely punctate, except along the narrow, smooth, raised, median line. Elytra much wider

the base to the apex, 8 and 10 at the base, and the suture also, sharply costate, the other interstices fiat.

Legs stout ; intermediate and posterior tibize sharply angulate externally and ciliate thence to the apex.

Length 62-94, breadth 32-5 millim. (d 9-)

Hab. Mexico, Jalapa (Hége); Panama, Volcan de Chiriqui (Champion).

Described from a pair from Jalapa, the single specimen (2) from Chiriqui being

much larger, smoother, and more sparsely pubescent, and having the prothorax

emarginate in the centre in front. The contiguous eyes, the feebly carinate prothorax,

the less oblong elytra, and the more abundant pubescence separate it from R. acute-

costatus.

7. Rhyssomatus latus, sp.n. (Tab. XVII. figg. 18, 154, ¢; 18 8, interm.

tibia.)

Short, broad, rhomboidal, shining, black, slightly mottled with rufo-piceous, the scape of the antenne

ferruginous, sparsely pubescent. Head densely, finely punctate, the eyes contiguous ; rostrum feebly

curved, rather slender, nearly twice as long as the prothorax, closely punctate, pluri-carinate in its basal

half, the antenne inserted a little behind the middle. Prothorax at the base more than twice as broad

as long, conical, strongly constricted in front, the base subtruncate; closely, obliquely strigose and finely,

shallowly punctate, the dise with a median carina extending from the apex to near the base. Elytra

broad, subtriangular, slightly wider than the prothorax at the base and dilated at the sides beneath the

prominent humeri; seriato-foveolate, the foves oblong in shape, the interstices slightly rugulose,

3,5, 7,9 from the base to the apex, 8 and 10 at the base, and the suture moderately, costate. Meso-

sternum protuberant anteriorly. Legs short and moderately stout; intermediate and posterior tibiz

sharply angulate externally and ciliate thence to the apex.

Length 53, breadth 34 millim. (2.)

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

One specimen. The short, subtriangular elytra, with moderately costate alternate

interstices, the short, conical, posteriorly dilated prothorax, the long rostrum, and the

short legs are the chief characters of this species.

s. Rhyssomatus latipennis, sp.n. (Tab. XVI. figg. 19, 19 a, 2.)

Short, broad, subrhomboidal, shining, black, mottled with rufo-piceous, the antenne, rostrum, and tarsi

ferruginous, very sparsely pubescent. Head densely, finely punctate, the eyes separated by nearly half

the width of the rostrum ; rostrum curved, stout, about as long as the head and prothorax, rugulosely

punctate, becoming smoother and more shining towards the tip, the antenne inserted at the middle.

Prothorax conical, short, at the base twice as broad as long, strongly compressed at the sides anteriorly,

the base subtruncate ; densely, finely punctate, the punctures separated by very narrow, oblique rugz, the

dise with a fine median carina, which does not reach the base. Elytra much wider than the prothorax,

feebly dilated at the sides beneath the rounded, prominent humeri, and narrowing thence to the apex ;

seriato-foveolate, the interstices slightly rugulose, 3, 5,7 very sharply costate throughout, and 8 at the

base, and 9 and 10, more feebly costate, the others flat, the suture also raised. Mesosternum not

protuberant. Legs short and rather slender ; intermediate and posterior tibiee feebly angulate externally

and ciliate thence to the apex.

RHYSSOMATUS., 331

One specimen. Recognizable by its small, conical, anteriorly constricted prothorax,

and broad, comparatively short elytra, with very sharply costate alternate interstices,

the suture moderately raised. Smaller than &. latus, the rostrum much shorter,

smoother, and stouter, the eyes more distant, the prothorax narrower, the elytra with

more rounded humeri, and much more strongly costate alternate dorsal interstices.

9. Rhyssomatus parvulus, sp. n.

Short, somewhat rhomboidal, dull, black or nigro-piceous, the antenne and tarsi ferruginous, very sparsely and

finely pubescent. Head rugulosely punctate, the eyes very narrowly separated; rostrum strongly curved,

stout, about as long as the head and prothorax, rugulose and pluri-carinate in its basal half and sparsely

punctate and shining thence to the apex, a little smoother in the 9, the antenne inserted at or near the

middle. Prothorax short, conical, constricted in front, rather coarsely, confluently punctate, the punctures

separated by short, oblique, raised lines, the disc finely carinate down the middle. Elytra much wider

than the prothorax, short, somewhat triangular, the humeri obtuse and laterally prominent ; punctato-

sulcate, the interstices alutaceous, 3, 5, 7, 9 finely costate throughout and 8 costate at the base, the others

flat. Legs short; intermediate and posterior tibie feebly angulate externally and ciliate thence to the

apex ; tarsal claws subapproximate.

Length 2;/,-23, breadth 1j-14 millim. (¢ @.)

Hab. Mexico, Acapulco, Oaxaca (Hoge), Teapa (H. H. Smith); Guatemata, Paraiso,

Zapote, Capetillo (Champion).

Nine specimens. This is the smallest of the Central-American Ahyssomati, and

easily identified by its conical, rugose prothorax, the short, subtriangular, dull elytra,

with finely costate alternate interstices, the reddish tarsi and antenne, and the strongly

curved rostrum. In general shape it approaches Lt. latipennis. In the British Museum

there is a Colombian insect very like &. parvulus, labelled with the MS. name

R. pullus, SJekel. From &. minutus, Kirsch, from Peru and Venezuela, the present

species differs in its blacker colour, and probably in other particulars.

10. Rhyssomatus laticollis, sp.n. (Tab. XVII. figg. 20, 20 a.)

Broad, oval, shining, nigro-piceous, slightly mottled with rufo-piceous above, the antenne obscure ferruginous,

very sparsely pubescent. Head densely, rugulosely punctate, the eyes contiguous; rostrum stout, slightly

curved, a little longer than the prothorax, rugulosely punctate and pluri-carinate in its basal half and

sparsely punctate thence to the tip, the antenne inserted about the middle. Prothorax short, at the base

rather more than twice as broad as long, narrowing forwards and abruptly constricted in front, the base

feebly sinuate ; closely, obliquely strigose, and also finely punctate, the disc with a very fine median

carina. LElytra considerably wider than the prothorax, subcordate, slightly dilated at the sides beneath

the rounded humeri; seriato-foveolate, the foves placed in very shallow striz, the interstices slightly

rugulose, 3, 5, 7, 9 sharply costate throughout, and 8 and 10 costate at the base, the suture also raised.

Mesosternum protuberant in front. Legs short; intermediate and posterior tibie sharply angulate

externally and ciliate thence to the apex.

broad, short prothorax, which is narrowed from the base and abruptly constricted in

front, and the short, subcordate, seriato-foveolate elytra.

11. Rhyssomatus biseriatus, sp. n.

Oval, shining, black, the antenne and tarsi obscure ferruginous, very finely and sparsely pubescent. Head

densely, rugulosely punctate, the eyes narrowly separated; rostrum stout, feebly curved, about as long as

the head and prothorax, closely, rugulosely punctate, becoming smoother towards the tip, feebly carinate

at the base, the antenne inserted at the middle. Prothorax at the base twice as broad as long, gradually

narrowing forwards and abruptly constricted in front; coarsely, closely, obliquely strigose and with an

incomplete median carina. Elytra wider than the prothorax, narrowing from a little below the humeri;

seriato-foveolate, the interstices almost smooth, 3, 5, 7, 9 sharply costate from the base to the apex, and

8 and 10 costate at the base, the suture also raised. Legs stout; intermediate and posterior tibie sharply

angulate externally and ciliate thence to the apex.

Length 54-53, breadth 24 millim. ( 2.)

Hab. Mexico, Tapachula (Sallé); Guarmmata, Las Mercedes (Champion)..

Two females, both from the Pacific slope. This species resembles JZ. acutecostatus

in the elytral sculpture, but has the prothorax shaped very much as in R. yucatanus,

with the coarse strigosity oblique, instead of longitudinal. The very sharply costate,

glossy elytra, and the differently shaped, coarsely sculptured prothorax, separate it

from R. sculpticollis, R. sculpturatus, &c.; and the narrower general shape, the non-

contiguous eyes, and the more coarsely sculptured prothorax, from £. laticollis.

12. Rhyssomatus sculpticollis, sp.n. (Tab. XVII. figg. 21, 214, ¢.)

Oblong-oval, dull, piceous or black, the elytra often mottled with rufo-piceous, the antennz and tarsi obscure

ferruginous, sparsely clothed with ochreous pubescence. Head densely, rugulosely punctate, the eyes

very narrowly separated ; rostrum (3) feebly curved, stout, nearly as long as the head and prothorax,

rugulosely punctate and obsoletely pluri-carinate, (2 ) much smoother, the antenne inserted at the middle

in the @ and a little before the middle in the ¢. Prothorax strongly transverse, ronnded at the sides,

narrowing forwards, constricted in front; closely, obliquely strigose, and with a fine median carina, which

does not reach the base. Elytra wider than the prothorax, gradually narrowing from a little below the

humeri; punctate-striate, the strie shallow, but becoming deeper towards the apex, the punctures coarse

and oblong, the interstices somewhat rugulose and very sparsely, obsoletely granulate, 3, 5, 7,9 moderately

costate from the base to the apex, and 8 also costate at the base, the others flat. Legs short ; intermediate

and posterior tibize sharply angulate externally and ciliate thence to the apex.

several very closely allied forms with obliquely strigose pronotum (a character separating

it from R. rugulipennis) and alternately costate elytral interstices, and chiefly distin-

guishable by the sparse pubescence and the feebly rugulose elytra. Compared with

appears to be more oval in shape. The following is perhaps an extreme form of it.

13. Rhyssomatus sculpturatus, sp. n.

Very like BR. sculpticollcs, but more closely pubescent, the pubescence on the elytra often fasciculate ; the elytra

themselves a little more widened anteriorly (their general shape subcordate), with the interstices more

closely and distinctly rugulose, in some specimens rufescent mottled with black.

Length 4—73, breadth 23-3? millim. (¢ 9.)

Hab. Mexico, Villa Lerdo in Durango, Matamoros Izucar, Acapulco, Jalapa,

Cordova, Tapachula (Hége), Chilpancingo, Amula, Tepetlapa, Cuernavaca (HH. H.

Smith), Oaxaca (Sal/é).

Twenty-two specimens. Also very like the North-American &. palmacollis, but

with the elytra less opaque and more distinctly striate, the interstices rugulose.

Var.?

The third and fifth elytral interstices not costate to the base; the pubescence sparser.

Five specimens.

14. Rhyssomatus punctato-sulcatus, sp. n.

Oval, rather dull, nigro- or rufo-piceous, the antennz and tarsi obscure ferruginous, finely pubescent. Head

densely, rugulosely punctate, the eyes almost or quite contiguous; rostrum (¢) stout, feebly curved,

about as long as the head and prothorax, closely, rugulosely punctate, and obsoletely pluri-carinate in its

basal half, (2) a little longer, more slender, almost straight, and much smoother in its apical half, the

antenne inserted at the middle in the 9, and nearer the apex in the ¢. Prothorax strongly transverse,

narrowing from the base, slightly rounded at the sides anteriorly, and constricted in front; closely,

obliquely strigose, with, at most, the faintest indication of a median carina. Elytra wider than the

prothorax, oval; punctato-sulcate, the punctures deep and oblong in shape, the interstices closely and

finely rugulose, 3, 5, 7, 9 moderately costate from the base to the apex, and 8 and 10 costate at the base,

the suture also raised. Legs short, moderately stout ; intermediate and posterior tibie sharply angulate

externally and ciliate thence to the apex.

Hab. Mexico, Chilpancingo (H. H. Smith), Tapachula (Hoge); Guatemana, Las

Mercedes (Champion).

Five specimens, all from the Pacific slope. ‘This insect closely resembles R. sculpti-

collis, but may be recognized by the sulcate elytra, the more contiguous eyes, and the

almost straight rostrum of the female, the latter being similarly curved in the two

sexes of R. sculpticollis. The median carina of the prothorax is usually obsolete.

15. Rhyssomatus debilis, sp.n. (Tab. XVII. figg. 22, 224, ¢.)

Oval, rather dull, piceous or rufo-piceous, the elytra slightly mottled with blackish, the antenne and tarsi

ferruginous, finely pubescent. Head rugulosely punctate, the eyes very narrowly separated; rostrum

stout, feebly curved, a little longer than the prothorax, rugosely punctate and finely carinate, the antenne

inserted at about one-third from the apex. Prothorax strongly transverse, feebly rounded at the sides,

narrowing from the base, constricted in front, closely, shallowly, obliquely strigose, without trace of a

median carina. Elytra much wider than the prothorax, oblong-oval ; punctato-suleate, the interstices

densely, very finely rugulose, 3, 5, and 7 narrowly costate throughout, and 8 and 9 also a little raised.

Legs short, rather slender; intermediate and posterior tibie angulate externally; tarsal claws

subapproximate.

Length 3-3,5, breadth 13 millim. (<.)

Hab. Mexico, Jalapa (Hége); Guatemata, El Jicaro in Vera Paz (Champion) ;

Panama, Volcan de Chiriqui (Champion).

Four specimens. A small species, with short, comparatively narrow, shallowly

strigose prothorax, and dull, punctato-sulcate, oblong-oval elytra, the latter with the

alternate interstices somewhat feebly costate from the base to the apex. It is most

nearly allied to &. punctato-sulcatus.

16. Rhyssomatus alternans, sp. n.

Subrhomboidal, rather short, shining, rufo-piceous, very sparsely and finely pubescent. Head densely,

rugulosely punctate, the eyes contiguous; rostrum stout, curved, longer than the head and prothorax,

very sparsely, finely punctate, carinate at the base, the antennte inserted before the middle. Prothorax

at the base twice as broad as long, conical, strongly constricted in front, closely, obliquely strigose, and

also very finely punctate, the disc with a fine median carina, which does not reach the base. Elytra

much wider than the prothorax,. narrowing from the prominent, rounded humeri; deeply punctate-

striate, the punctures oblong in shape, the interstices slightly rugulose, 3, 5, 7, 9 sharply costate from the

base to the apex, and 8 and 10 also costate at the base, the others flat. Anterior coxe widely separated.

Legs comparatively slender ; intermediate and posterior tibie sharply angulate on their outer edge and

ciliate thence to the apex.

Length 32-4, breadth 25-24 millim. (<¢.)

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

Three specimens, probably all males. The widely separated anterior coxe, the short,

conical, obliquely strigose prothorax, and the punctate-striate elytra, with costate

alternate interstices, sufficiently distinguish A. alternans.

Rhyssomatus rufus, Fabr. in Schénh. Gen. Cure. iv. p. 369’; Schénh. op. cit. viii. 2, p. 11.

Very like 2. subrufus, but smaller, the eyes more approximate, the head distinctly foveate between them; the

rostrum less curved and much shorter, not depressed at the base above, not longer than the head and

prothorax, in the g deeply punctato-sulcate and 5-carinate, and in the Q longitudinally strigose, in its

ridge on 2, 4, and 6 not quite reaching the base.

20. Rhyssomatus ovalis.

Rhyssematus ovalis, Casey, Ann. N. York Acad. Sci. vi. p. 443°.

Oval, moderately shining, rufo-piceous, almost glabrous. Head closely punctate, faintly foveate between the

Hab. Nortu America, Texas !.—Mexico, Matamoros Izucar in Puebla (Hége).

One specimen. In the widely separated eyes this species approaches &. nigerrimus,

but in general facies it is extremely like A. pruinosus, differing from the latter in the

form of the tibie, tarsi, and rostrum. The deeply punctato-sulcate elytra, with convex,

closely punctate interstices, readily distinguish 2. ovalis from the other Central-

American forms. Mr. Wickham has sent us two examples of it from Uvalde, Texas.

21. Rhyssomatus subrufus, sp.n. (Tab. XVII. fig. 26, ¢ , head and rostrum.)

Oval, shining, piceous, rufo-piceous, or ferruginous, very sparsely pubescent, the pubescence somewhat clustered

into fascicles on the elytra. Head finely punctate, the eyes well-separated ; rostrum (¢ ) rather slender,

curved, depressed at the base above, longer than the head and prothorax, very sparsely, finely punctate,

and longitudinally strigose towards the base, ( Q ) a little longer and more slender, almost smooth from

an almost continuous outline with the prothorax ; seriato-foveolate, the punctures placed in deep grooves

at the sides and beyond the middle, the interstices rugulose and rather convex, the outer ones, and 3

and 5 from the middle to the apex, costate. Fifth ventral segment deeply foveate in the ¢, and shallowly

so inthe 9. Legs short; tibiae with the apical claw very long, the intermediate and hind pairs feebly

RHYSSOMATUS. 337

Three females and one male, agreeing very nearly with Dr. Horn’s description, and

with two Texan specimens sent me by Mr. Wickham. The dilated tarsi, the sinuato-

emarginate outer edge of the intermediate and hind tibie, and the very slender, curved,

basally deflexed rostrum, readily distinguish R. pruinosus from its Central-American

allies. According to Boheman!, the insect has an eneous lustre, but this is not visible

in the specimens described by Dr. Horn 2, norin those before me. The three examples

from Yucatan have the prothorax more coarsely punctured than the others.

Paz (Champion); Panama, Bugaba, David, Caldera, San Feliz (Champion).

In this insect the elytra, which are sometimes castaneous, are very coarsely seriate-

punctate, with all the interstices costate towards the apex; the head is foveate between

the eyes, which are widely separated ; the rostrum is depressed at the base above, long,

curved, and slender; the prothorax in most of the Mexican specimens (as described

by Fahreus) is densely, obliquely strigose, except along the smooth, narrow, median

space, the sculpture becoming punctiform towards the middle of the disc, this being

especially noticeable in the examples from Guatemala and Panama, which have the

sides only strigose. The antenne are inserted somewhat behind the middle of the

rostrum in both sexes. The mesosternum is protuberant in front.

Easily distinguishable by its broad, oval form, the widely separated eyes, the long

rostrum, and the densely punctured upper surface, the elytra finely punctate-striate,

with flat interstices. The mesosternum is strongly protuberant in front. The inter-

mediate and posterior tibiz are very sharply angulate on the outer edge before the

apex. The antenne in the male are inserted at about the middle, and in the female

much nearer the base, of the rostrum, which is slender, deflexed at the base above, and

strongly curved in the female. The fifth ventral segment is deeply foveate in the

338 RHYNCHOPHORA.

This species is not represented in our collection, but I have seen the type (¢)

belonging to the Stockholm Museum. It is very like F. puneticollis, but wholly

greenish-zeneous above; the rostrum and prothorax are more coarsely punctate; the

seriate punctures on the elytra are coarser and more scattered, the interstices are more

uneven, and the alternate ones (3, 5, 7, 9) are sharply costate on the apical declivity,

and the legs are stouter and more rugose. ‘The antenne are inserted at one-third from

the base of the rostrum, ‘The intermediate and hind tibie are straight on their outer

edge ; the anterior pair strongly sinuate within. The tarsal claws are cleft and closely

approximate, The anterior coxe are widely separated.

26. Rhyssomatus puncticollis, sp. n.

Oval, convex, shining, eneo-piceous, the elytra rufescent, the prothorax and legs with a brassy lustre, almost

glabrous. Head closely, minutely punctate, faintly foveate above the eyes, which are contiguous ; rostrum

stout, becoming a little thicker towards the base, scarcely as long as the prothorax, feebly curved, closely, -

finely punctate, the antentie inserted near the base. Prothorax broader than long, slightly rounded

at the sides, narrowing from the base, constricted on each side in front, thickly punctate, the punctuation

becoming coarser on the flanks, the dise with a narrow smooth space along the middle. Elytra forming

an almost continuous outline with the prothorax; coarsely and deeply seriate-punctate, the interstices

flat and almost smooth, 3 very sharply, and 4-9 more feebly, costate on the apical declivity. Anterior

coxee widely separated. Legs short, rather slender; anterior and intermediate tibie straight on their

outer edge; tarsal claws approximate.

declivity. The tarsal claws are so closely approximate that the inner tooth is not

easily seen. Its differences from 2. viridipes are noted above.

27. Rhyssomatus nitidus, sp.n. (Tab. XVII. figg. 30, 30a, 2; 80%, interm.

Oval, convex, shining, rufo-piceous, the elytra ferruginous, almost glabrous. Head minutely punctate,

obsoletely foveate above the eyes, which are separated by a thin lamella only; rostrum stout, almost

straight, about as long as the head and prothorax, sparsely punctate throughout, without trace of carina,

the antenne inserted near the base, the scrobes, however, extending forwards to beyond the middle.

Prothorax broader than long, conical, slightly constricted in front, strongly bisinuate at the base; some-

what closely, minutely punctate, the punctuation becoming much coarser at the sides, the disc with a

smooth median line. Elytra much wider than the prothorax, narrowing from the rounded humeri, which

in front form an almost continuous outline with the sides of the prothorax ; coarsely and deeply seriate-

punctate, the punctures rounded and each placed in a larger and darker spot showing through from

beneath, the interstices flat, becoming convex on the apical declivity, and very sparsely, minutely punctate.

One specimen. The conical, finely punctured prothorax, the coarsely seriate-punctate

elytra, with the interstices flat to near the apex, the widely separated anterior coxe,

Edesius, Pascoe, Ann. & Mag. Nat. Hist. (5) vii. p. 805 (1881). -

An American genus including innumerable species, about 200 having been described,

and nearly as many * are now known from our region, whence eight only have previously

been recorded. It is chiefly recognizable by the open rostral canal, the prominent

ocular lobes to the prothorax, and the toothed or appendiculate, divergent, tarsal claws.

The alternate elytral interstices are usually costate, and the dorsal ridges are often

interrupted and separated into two or more lamelliform prominences, the median one

on the third interstice being sometimes very conspicuous. ‘The species with a deeply

excavate mesosternum, belonging to the Stirps 2 of Schénherr’s arrangement (=Sect. E

of the Table given below), might be excluded, but they are connected with the rest by

the intermediate forms here placed under Sections C and D, The character used by

him for his Manipulus I. of Stirps 1 was perhaps taken from female specimens only.

C. lobatus, C. scoparius, and others have the posterior tibie peculiarly formed in the male.

C. rectirostris and its allies, as well as C. incanus, &c., have the rostrum longer, smoother,

and more slender in the female than in the male, and the antenne inserted much

further from the apex ; but this difference becomes less marked and finally disappears

as the rostrum becomes shorter and stouter. C. nodifer and C. elongatus (species very

like the South-American C. leucostictus, Boh.) have a peculiar facies, owing to their

oblong shape and the elevations on the outer elytral interstices being reduced to

scattered tubercles. Cyphorhynchus was based upon a few species with the rostrum

short, and gibbous at the base; and Edesivs upon an insect with very widely separated

intermediate coxa, a concave mesosternum, and densely squamose upper surface.

C. nenuphar, Herbst, and various other North-American Conotracheli are said to be

very destructive to stone-fruits, such as the plum, apricot, &c.

The following Table will assist in the identification of the Central-American forms;

but it must not be relied upon altogether, as the two sexes of some of them are not

known in every case, the mesosternal and other characters gradually merge one into

the other, and the elytral coste sometimes vary in development in the same species.

It is probable that some of those from Panama treated as new will ultimately prove to

Fourteen examples. Very like C. fulvescens, but distinguishable at once by the

irregularly serrate posterior femoral tooth. C. diaconitus and C. lassulus, Boh., from

Cuba, and C. porculeti and C. distinctus, Boh., from Brazil, are described as having a

somewhat similar armature. C. serratidens is a more elongate insect than C. diaconitus.

rostrum (2) shorter, less curved, and striate at the base ; the prothorax with a stout

median carina; the elytra with the vestiture whitish and fasciculate on the alternate

interstices. ‘The armature of the femora is different from that of any other species

here described ; the anterior pair, however, are formed as in C. serratidens.

6. Conotrachelus tetrastigma, sp.n. (Tab. XVIII. figg. 6, 6a, 3; 7, 2.)

Oblong-ovate, rather dull, piceous or rufo-piceous ; the vestiture sparse, ochreous or whitish, here and there

subfasciculate on the elytra, the prothorax with a sinuous, irregular line on each side of the disc, the

ochreous scales; the femora with a ring of whitish scales a little beyond the middle, the anterior pair

with a dense line of fulvous or ochreous scales along their basal third above. Head densely punctate,

foveate between the eyes; rostrum strongly curved, in the g moderately stout, about twice as long as

the prothorax, depressed at the base above, and 5-carinate, in the Q much smoother, more slender,

Hab. Mexico, Jalapa (Hége); Guatemaua, San Gerdénimo (Champion).

Six females and three males, the former varying in the extent of the curvature

of the rostrum. The very long, comparatively slender, almost smooth rostrum

of the female, and the uninterrupted second elytral costa, separate this species from

the other similarly-coloured Central-American forms. The inner tooth of the tarsal

claw is longer than in C. inexplicatus. ‘This is one of several nearly allied species

resembling C. quadrinotatus in general coloration.

7. Conotrachelus quadrinotatus.

CONOTRACHELUS. 347

Found in abundance in Chiriqui, a few specimens only having been received from the

more northern localities. The median carina on the prothorax is often obsolete. ‘The

subapical spots on the elytra are sometimes evanescent, the scales, too, varying in

size. The type (2), from Brazil, has larger spots and some scattered coarse scales

towards the tip, but otherwise agrees with the Central-American examples.

8. Conotrachelus rectirostris, sp.n. (Tab. XVIII. fig. 8, 2.)

Oblong-ovate, moderately shining, rufo-piceous; the vestiture rather long, somewhat close, ochreous and

whitish intermixed, that on the prothorax condensed into a faint oblique line on each side of the disc and

a longitudinal one on the flanks, the humeri sometimes with a small patch of ochreous scales in front ;

the femora with a denser ring of ochreous or whitish scales beyond the middle, the anterior pair with a

dense line of ochreous scales at the base above. Head closely punctate, foveate between the eyes;

rostrum (¢ ) rather slender, feebly curved, depressed at the base above, nearly half the length of the

body, 5-carinate, thickly punctured at the apex, (2) almost straight, slender, and simply striate,

the apical half almost impunctate, the antennee inserted at about one-fourth from the apex in the

3, and a little beyond the middle in the 9, joints 1 and 2 of the funiculus subequal in length.

Prothorax broader than long, constricted and abruptly narrowed in front, subparallel behind, strongly

bisinuate at the base; coarsely, confluently punctate, and often feebly carinate down the middle

anteriorly. Elytra oblong-oval, strongly bisinuate at the base, the humeri rounded; coarsely seriate-

punctate, the interstices rugulose, 3, 5, 7, and 9 costate, the ridge on 3 twice interrupted for a short

distance, and that on 5 or 7 sometimes incomplete. Mesosternum flattened between the coxee, feebly

bituberculate in front. Ventral segments shining, very sparsely, minutely punctate. Femora clavate,

each with a broad acute triangular tooth. Tarsal claws with a long tooth.

Length 62-74, breadth 33-32 millim. (¢ 2.)

Hab. Guaremata, Mirandilla (Champion: 3 2); Panama, Bugaba (Champion: 3 @ ).

Six specimens, four of which are from Guatemala. A small female from San

Ger6énimo, Guatemala, with a smoother and shorter rostrum, may also belong here.

Recognizable from C. guadrinotatus and its alles by the absence of the dense patches

of scales on the elytra, the additional faint ochreous line on the flanks of the

prothorax, and the less prominent humeri. ‘To judge from the description, C. recti-

rostris approaches the South-American C. mamillatus, Boh. ; but it has a smoother

rostrum and the ridge on the third elytral interstice is twice interrupted. There

is a female of an unnamed species from Brazil in the British Museum that comes very

near the present insect.

Numerous examples. Perhaps a form of C. rectirostris, from which it may be

separated by the structure of the rostrum, the difference being well-marked in the

females, and in the feebly-notched anterior femoral tooth. C. guadrinotatus bears a

somewhat similar relationship to C. tetrastigma.

thorax strongly transverse, narrowed and constricted in front, deeply bisinnate at the base, densely,

rugulosely punctate. Elytra subtriangular, about one-half wider than the prothorax, strongly sinuate at

the base, the humeri prominent, but obtuse; coarsely seriate-punctate, striate near the suture, the

interstices rugulose, 3, 5, 7, and 9 sharply costate, the ridge on 3 and 5 abruptly twice interrupted, the

median elevation on 3 very prominent. Mesosternum simply flattened between the coxe. Ventral

One pair. ‘This species somewhat resembles C. dentiferus, but the vestiture is

sparser and differently coloured above (though very dense on the flanks of the

prothorax), the elytra have a large reddish humeral patch, the rostrum of the female is

elongate and also very much smoother than that of the male, with the antenne inserted

at the middle, the femora acutely unidentate, the posterior tibie dilated at the apex, &c.

Hab. Mexico, Colima city ({ége).

One female. ‘The very large, rather narrowly separated eyes, the almost smooth,

stout rostrum, the feebly developed ocular lobes of the prothorax, the anteriorly

flattened, subtriangular elytra, with the vestiture becoming much denser towards the

Hab. Panama, Bugaba, Volcan de Chiriqui, Caldera, David, Tolé (Champion).

A common insect in the savana-region of Chiriqui. It is easily distinguishable by

its abruptly narrowed rostrum, this being especially noticeable in the female. In this

respect C. subulatus approaches the Anthonomid-genus Listrorrhynchus. C. brevicollis

is an allied form.

de Chiriqui (Champion).—CotomBia ; VENEZUELA, Colonia Tovar !, Caracas.

Found in abundance at Cerro Zunil and also in Chiriqui, some of the specimens

agreeing well with a co-type from Venezuela sent me by Dr. Heller. A species of

large size (varying from 62-8 millim. in length), piceous or rufo-piceous in colour,

with a broad, anteriorly attenuate vitta on each side of the prothorax, a transverse

patch at the shoulder and an oblong mark at the apex of each elytron, and a trans-

verse patch on the prosternum, densely clothed with ochreous or whitish scales.

The femora have a minute tooth exterior to the larger one, which is very sharp

on the posterior pair; they are annulate with whitish or ochreous a little beyond

the middle, and on the anterior pair above there is a dense line of fulvous scales

extending along their basal half. The tarsal claws have a short tooth. The male has

a stouter and more arched rostrum than the female. ‘The sculpture of the elytra is

rather variable. C. inexplicatus is a close ally of C. amabdilis, Boh., from Cayenne, the

latter having a large oblong patch at the base of each elytron.

culate on the elytra, the prothorax with a sinuous line on each side of the disc, the elytra with an

interrupted transverse patch at the shoulder and a small spot on the subapical callus, and the prosternum

with a transverse space in front of the anterior coxe, densely clothed with ochreous scales; the femora

with a ring of whitish scales a little beyond the middle, the anterior pair with at most a faint line of

fulvous scales at the base above. Head densely, rugosely punctate; rostrum exceedingly stout, strongly

Eight specimens, differing from a co-type from Peru in their larger size and shorter

femoral teeth. In this insect the vestiture of the upper surface is fine and of a uniform

dark reddish-brown colour, and the dense patches of whitish scales are very sharply

defined. ‘The finer vestiture, the larger outer femoral tooth, the smaller seriate punctures

on the elytra, &c., separate C. stgnatus from C. guadrinotatus and C. quadripustulatus.

This species seems to be a near ally of C. repens, Boh., from Brazil, but the vestiture

is closer and differently coloured ; the whitish markings, however, are very similar,

Found in abundance in Chiriqui. ‘The variety (?) is represented by four specimens

{rom the more northern localities. This species approaches C. inexplicatus, but it is

smaller, more coarsely punctured above, and wants the large dense patches of ochreous

scales on the prothorax and elytra, &c. ‘The short tooth of the tarsal claws, the

smaller femoral tooth, the sparse vestiture, &c., separate it from C. rectirostris and

others. ©. rugicollis, Boh., from Antioquia, is also an ally of C. cribratus, but it has

a still more coarsely punctured prothorax and more sharply costate elytra.

37. Conotrachelus impressicollis, sp. n.

Subovate, moderately shining, black or nigro-piceous, the antenne and the tips of the tarsi obscure ferruginous ;

the vestiture scattered, long, and rather coarse, fulvous and white intermixed, the whito scales tending to

scales extending along their basal third above. Head closely punctate, foveate between the eyes;

rostrum (¢) stout, moderately curved, slightly longer than the head and prothorax, 5-carinate, thickly

punctate at the tip, (2) longer, straighter, less curved, and much smoother, the antenne inserted at

Hab. Panama, Volcan de Chiriqui (Champion).

Three specimens. ‘This insect is very like C. foveicollis, but the femora are feebly

unidentate, the elytral costz are not so prominent and less interrupted, the tibie are

infuscate, and the vestiture of the upper surface is greyish, except at the base of the

elytra, where it is rather broadly fulvous. There is an allied form from Colombia in

the British Museum with the elytral costee uninterrupted and very prominent.

42. Conotrachelus unidentatus, sp. n.

Subovate, somewhat shining, nigro-piceous or black, the antenne and the tips of the tarsi ferruginous; the

vestiture very sparse, fine, and whitish, slightly fasciculate on the elytra, becoming longer, yellowish, and

very scattered on the prothorax, the anterior femora with a narrow line of fulvous scales at the base above.

Head closely, rugosely punctate ; rostrum exceedingly stout, curved, tapering outwardly, as long as the

head and prothorax, seriate-punctate and 5-carinate, sparsely punctured at the apex, the antenne stout,

inserted at about one-fourth from the tip, joint 2 of the funiculus much shorter than 1. Prothorax

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

Four specimens. The whitish vestiture of the elytra, the very coarse sculpture of

the prothorax, the stout legs, the sinuous inner edge of the anterior tibie, and the

unidentate femora, distinguish C. wnidentatus from most of its allies.

43. Conotrachelus fasciculatus, sp. n.

Oblong-ovate, subopaque, nigro- or rufo-piceous; the vestiture very sparse, ochreous above and condensed

into a small patch at each of the hind angles of the prothorax and numerous others on the elytra, that

of the under surface and legs whitish, the elytra also with short, scattered, ochreous set. Head densely

punctate, foveate between the eyes; rostrum ( ¢') stout, curved, about as long as the head and prothorax,

5-carinate, thickly punctate at the tip, (2) a little longer and much smoother, the antenne in the ¢

inserted at one-fourth, and in the Q at one-third, from the apex, joints 1 and 2 of the funiculus equal

Hab. Panama, Volcan de Chiriqui 5000 feet (Champion).

The description of this insect is taken from three specimens; a fourth has the

sculpture of the prothorax and elytra coarser, and indications of a second very minute

tooth on the femora at some distance from the other. The shortly setose elytra, the

feebly bisinuate base of the prothorax, the moderately coarse sculpture of the latter,

and the not very prominent femoral tooth, distinguish C. fasciculatus from its

immediate allies.

44, Conotrachelus picticollis, sp.n. (Tab. XIX. figg. 4, 4a, 3; 46, anterior

femur.)

Oblong-ovate, dull, nigro-piceous or black; the vestiture very sparse, ochreous above, whitish beneath and on

the legs, that on the elytra here and there condensed and fasciculate, and that on the prothorax condensed

into two small spots on the disc a little behind the middle and another at each hind angle, the anterior

femora with a narrow line of ochreous scales at the base above. Head closely, rugosely punctate ;

rostrum stout, curved, a little longer than the head and prothorax, rugulose and 5-carinate in both sexes,

the apical portion closely punctate in the $ and smoother in the 9, the antenne in the ¢ inserted at

one-fourth, and in the 2 at one-third, from the tip, joints 1 and 2 of the funiculus equal in length.

Prothorax broader than long, rounded at the sides anteriorly, narrowed and feebly constricted in front,

bisinuate at the base; densely, rugosely punctate, carinate down the middle anteriorly. Elytra con-

stricted at the sides below the humeri, narrowing from about the basal third; seriate-punctate, the

interstices rugulose and obsoletely granulate, 3, 5, 7, and 9 costate, the ridge on 3, 5, and 7 abruptly

twice interrupted. Mesosternum flat between the coxe, protuberant and bituberculate in front.

Ventral segments shining, sparsely, finely punctate. Femora clavate, rugose, each armed with a stout

triangular tooth, and with a small tooth placed nearly midway between it and the apex. Tarsal claws

with a short tooth.

Length 63-775, breadth 33-3% millim. (3 9.)

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

Three specimens. The protuberant, bituberculate mesosternum, the dense, mode-

rately coarse sculpture of the prothorax, the disc of the latter having two conspicuous

ochreous spots, the fasciculate arrangement of the elytral vestiture, the dull upper

surface, and the bidentate femora, are the chief characters of this species. It is very

like C. bedentatus, Boh., from Colombia (the type of which I have seen), but has the

prothorax much more finely punctured, and wanting the four tubercles on the disc.

45. Conotrachelus lineatipes, sp. n.

Subovate, slightly shining, nigro-piceous or black, the tarsi and antenne partly reddish; the vestiture very

sparse, ochreous above and whitish beneath and on the legs, that on the elytra subfasciculate, and that

on the prothorax condensed into two small spots on the disc before the middle and another at each hind

angle, the femora sometimes with a faint whitish ring, the anterior pair with a rather broad line of

fulvous scales along their basal half above. Head densely, rugosely punctate ; rostrum curved, stout,

considerably longer than the head and prothorax, 5-carinate, sparsely punctate at the tip, the antenne

Prothorax broader than long, narrowed and constricted in front, sinuate or crenulate at the sides,

strongly bisinuate at the base ; coarsely, rugosely punctate, carinate down the middle anteriorly. Elytra

constricted at the sides below the humeri, and rapidly narrowing from about the basal third ; seriate-

punctate, the interstices slightly rugulose, feebly granulate at the base, 3, 5, 7, and 9 sharply costate, the

ridge on 3 and 5 twice, and that on 7 once, abruptly interrupted. Mesosternum flattened between the

coxee, obsoletely bituberculate in front. Ventral segments sparsely, finely punctate. Femora each with

a sharp triangular tooth and a minute tooth or prominence placed at some distance from it towards the

apex. ‘Tarsal claws with a moderately long tooth.

Hab. Guatemata, Sabo in Vera Paz (Champion); Panama, Bugaba, Volcan de

Chiriqui (Champion).

Eight specimens (possibly including both sexes), one only being from Guatemala

and perhaps wrongly labelled. ‘The conspicuous, rather broad line of fulvous scales

on the anterior femora, the two minute ochreous spots on the disc of the prothorax

towards the apex, and the small tooth or prominence on the femora at some distance

from the larger one, separate C. lineatipes from most of the various other very similar

Conotracheli. C. ethiops, Kirsch, from Ecuador, is not unlike C. lineatipes, but is

more depressed and has the anterior femora obsoletely dentate. |

46. Conotrachelus multiguttatus, sp. n.

Very like C. lineatipes, but shining; the prothorax a little less transverse, more coarsely rugose, and almost

bare, except for the two minute condensed ochreous spots on the disc before the middle and the similar

spot at each hind angle; the elytra more coarsely seriate-punctate, the ochreous vestiture condensed into

numerous small well-defined spots; the line of fulvous or ochreous scales on the anterior femora very

narrow.

(nec Lec.), from Colombia, but smaller, and with much shorter elytra, a more rugose

head, shorter legs and rostrum, &c.

47. Conotrachelus curtirostris, sp. n.

Subovate, shining, black, the upper surface mottled with rufo-piceous, the legs (the base of the femora

excepted) and antenne in great part ferruginous ; the vestiture rather close above, very sparse beneath,

fulvous, that on the legs intermixed with white, the elytra with a faint whitish fascia beyond the middle

and a small condensed fulyous patch on the humeri, and also set with very short, fine, pallid, semiereci;

Anterior tibie sinuate within. Tarsal claws with a short tooth.

Length 44, breadth 23 millim. (d.)

Hab. Panama, Tolé (Champion).

One specimen. A species with a short, stout, unicarinate rostrum, rather narrowly

separated eyes, a short prothorax, with the disc obliquely depressed on each side

anteriorly, and abruptly interrupted dorsal coste of the elytra. It is perhaps nearest

allied to C. lineatipes.

48. Conotrachelus rufitarsis, sp. n.

Oblong-ovate, very shining, deep black, the antenne and tarsi ferruginous; the vestiture very sparse, fine,

whitish, somewhat fasciculate on the elytra, condensed into a slightly curved yellowish line on each side

of the disc of the prothorax, the femora faintly annulate. Head closely punctuate, transversely depressed

between the eyes; rostrum very stout, arcuate, not longer than the head and prothorax, rugulosely

punctate and feebly 5-carinate, sparsely punctate at the tip, the antenne inserted near the apex, joints

Hab. Costa Rica, Irazu (Rogers).

One specimen. ‘The shining black surface and very sparse vestiture, the clear

ferruginous tarsi, the very abruptly interrupted dorsal coste of the elytra, &c.,

distinguish C. rufitarsis from C. multiguttatus, C. sinuaticollis, and others.

49. Conotrachelus sinuaticollis, sp.n. (Tab. XIX. fig. 5, anterior femur.) .

Oblong-ovate, moderately shining, varying in colour from black to rufo-piceous with darker markings (in one

immature specimen entirely ferruginous) ; the vestiture very sparse, ochreous above and whitish on the

legs and beneath, subfasciculate on the elytra, condensed into one or two minute spots on each side of

the disc of the prothorax and another at each hind angle, and a small patch at the base of the third

elytral interstice and another on the humeri in front, the femora each with a white annulus, the anterior

pair with a line of fulvous scales at the base above. Head rugosely punctate, sometimes foveate between

the eyes ; rostrum (3) stout, cylindrical, curved, slightly longer than the head and prothorax, 5-carinate,

Rica, La Palma (Biolley) ; Panama, Volcan de Chiriqui, Caldera (Champion).

Found in abundance at Cerro Zunil, sparingly elsewhere. ‘This is one of many very

similar forms, and mainly recognizable by the narrowly separated teeth of the anterior

femora, the rugose prothorax, the lateral margins of which are more or less sinuate

or angulate, and the cylindrical rostrum. Fresh specimens have two minute ochreous

spots on each side of the disc of the prothorax.

50. Conotrachelus germanus, sp. n.

Very like C. sinuaticollis, but with the triangular femoral tooth shorter, the minute outer prominence nearly

or quite obsolete ; the first and second elytral costee once or twice interrupted, the first sinuate beyond

the middle; the vestiture ochreous or fulvous above, condensed into larger patches at the base of the

elytra, and a small oblique spot on each side of the disc of the prothorax anteriorly ; the prothorax

transverse, with the sides subparallel and crenulate from the apical constriction to the base; the ventral

Segments sparsely, finely punctate.

Hab. Guatemata, Volcan de Atitlan, Sinanja (Champion).

Two specimens from the Volcan de Atitlan and one from Sinanja, differing too

much from C. sinuaticollis to be included under that species. ‘The very similar

C. fulvibasis has a less transverse prothorax, the anterior femoral tooth acute in both

sexes, the vestiture of the elytra (except at the base) intermixed with white, and the

dorsal coste less interrupted. The cylindrical rostrum separates C. germanus from

C. sinuatocostatus and C. segregatus.

51. Conotrachelus nigricans, sp. n.

Oblong-ovate, moderately shining, nigro-piceous or black, the elytra and legs usually more or less mottled

with rufo-piceous, the antenne sometimes ferruginous; the vestiture very sparse, fulvous or ochreous,

interstice and another on the shoulder, the elytra also set with very short, fine, decumbent, setiform

scales. Head densely, rugulosely punctate; rostrum very stout, arcuate, about as long as the head and

prothorax, densely, rugulosely punctate and feebly tricarinate, closely punctured at the apex, smoother

in its outer half in the 2, the antenne inserted towards the tip, joints 1 and 2 of the funiculus subequal

in length. Prothorax strongly transverse, slightly rounded at the sides, narrowed and compressed in

front, feebly bisinuate at the base; densely, rugulosely punctate, more or less distinctly carinate

anteriorly. Elytra obliquely constricted beneath the humeri and narrowing from a little beyond this to

the apex; seriate-punctate, the interstices rugulose or subgranulate, 3, 5, 7, and 9 costate, the ridge on

3 and 5 twice, and that on 7 once, interrupted. Mesosternum flattened between the coxw, moderately

protuberant and rounded or subtruncate in front. Ventral segments sparsely, somewhat coarsely

allies, but with the femora armed with two rather widely separated teeth (the outer

one minute, but distinct), the prothorax strongly transverse, the mesosternum sub-

truncate (not hollowed) in front, &c. The stouter rostrum, the absence of the

tubercles on the dise of the prothorax, the flat, mesially prominent mesosternum, &c.,

separate C. nigricans from C. crenatus.

52. Conotrachelus fulvopictus, sp. n.

prothorax and a minute spot at each hind angle, the elytra also with a small condensed patch at the base

of the third interstice and another on the shoulder, the femora with a whitish ring, the anterior pair

with a fulvous line at the base above. Head closely punctate, a little flattened in front; rostrum

cylindrical, stout, curved, not longer than the head and prothorax, rugulose and tricarinate, the apex

sparsely punctate in the ¢ and a little smoother in the 9, the antennae inserted towards the tip,

joint 2 of the funiculus slightly shorter than 1. Prothorax transverse, rounded at the sides anteriorly,

constricted and narrowed in front, deeply bisinuate at the base; coarsely, rngosely punctate, and

obsoletely carinate at the middle. Elytra about one-half wider than the prothorax, slightly compressed

beneath the rounded humeri and narrowing from a little beyond this to the apex, the base deeply

sinuate ; coarsely seriate-punctate, the interstices narrow, rugulose, 3, 5, 7, and 9 sharply costate, the

ridge on 3 and 5 depressed or interrupted below the base, that on 3 sinuous beyond the middle and

coalescent with that on 9 at the apex. Mesosternum flattened between the coxe, swollen on each side

Sent in abundance from Yucatan. This insect exactly resembles C. seniculus, Lec.

(a specimen of which has been sent me by Mr. Wickham), except that it has the

ventral segments much more sparsely and finely punctate. The allied C. affinis, Boh.,

is said by Leconte to have broad, sinuous, curved lines on the prothorax, and two

tubercles on the fifth ventral segment; and C. evegans, Boh., the ventral segments

coarsely punctate. The broad elytral fascia is sometimes whitish. The close vestiture

makes the upper surface appear opaque.

Subovate, rather dull, black or piceous, the antenne and tarsi more or less ferruginous ; the vestiture some-

what coarse, sparse, fulvous or greyish, closer, subfasciculate, and slightly intermixed with white on the

elytra, there being often two conspicuous white spots near the apex, the femora with a narrow whitish

ring. Head densely, rugulosely punctate, slightly depressed between the eyes above ; rostrum stout,

curved, about as long as the head and prothorax, rugulosely punctate and 5-carinate, in the Q much

Three specimens. A small species, recognizable by its shining surface and sparse

vestiture, the exceedingly stout, arched, tapering rostrum, the two small ochreous

patches at the base of each elytron, the inner one extending forwards along the disc

of the prothorax, and the annulate, unidentate femora, the anterior pair with a con-

spicuous line of fulvous scales. It is much smaller than C. /ineatipes, and has a very

differently shaped rostrum.

Subovate, slightly shining, piceous or rufo-piceous, more or less mottled with black, the antenne and the tips

of the tarsi ferruginous ; the vestiture very sparse, ochreous, condensed into a narrow oblique line on each

side of the disc of the prothorax and a faint spot within the humeri, becoming closer towards the sides

and on the apical declivity of the elytra, the femora with a faint ochreous or whitish ring beyond the

middle. Head rugosely punctate, somewhat depressed or flattened, and often feebly carinate, between

the eyes; rostrum (¢ 2) exceedingly stout, arched, tapering a little towards the tip, scarcely as long

Hab. Paxama, Bugaba, Volcan de Chiriqui (Champion).

Five specimens, one of which may be a female, as it has the rostrum a little

smoother and not quite so stout as in the others. ‘The dull surface, the condensed

oblique ochreous vitta on each side of the disc of the prothorax (extending from

opposite the eyes to the hind angles), the prominent median portion of the inner

costa on the elytra, and the distinctly bidentate femora, are the chief characters

of this species.

58. Conotrachelus mixtus, sp.n. (Tab. XIX. fige.7, 74, ¢; 7b, intermediate

leg, and 7 c, posterior leg, ¢ .)

Subovate, shining, black or piceous, the elytra and legs sometimes variegated with ferruginous, the antenne

A variable species, superficially resembling C. subulatus.

59. Conotrachelus continuus, sp. n.

Very like C. miatus, but with the rostrum a little longer, much smoother towards the tip, and the antenne

inserted further from the apex; the ridge on the third and fifth elytral interstices simply undulate,

uninterrupted ; the posterior tibia almost straight within.

Length 33-44, breadth 12-23 millim. (?¢ 2.)

Hab. Mexico, Jalapa (Hoge); Guatemata, San Gerénimo (Champion), Guatemala

Seven specimens, the one from Jalapa being probably a male and the others females.

Perhaps an extreme form of C. miatus, but if the sexes are correctly identified, the

lind tibize are similarly shaped in both male and female. C. continuus is also very

like C. sudulatus, but is separable at a glance by the shorter, non-subulate rostrum

and the more approximate eyes.

60. Conotrachelus bilineatus, sp.n. (Tab. XIX. figg. 8, Sa, ¢.)

Subovate, rather dull, varying in colour from piceous to ferruginous; the vestiture long, sparse, ochreous,

somewhat fasciculate on the elytra, and condensed into two narrow, sharply defined, anteriorly diverging

lines on each side of the prothorax, a line along the elytral humeri in front, and often a short streak at

the base of the third interstice, the femora usually with a narrow ochreous ring, the anterior pair with a

dense line of fulvous scales along the basal half above. Head rugosely punctate; rostrum very stout,

strongly curved, considerably longer than the head and prothorax, sharply 5-carinate in both sexes, closely

punctured at the tip, the apical portion longer, smoother, and narrower in the @, the antenne in the ¢

inserted at about one-fourth, and in the @ at one-third, from the apex, joints 1 and Y of the funiculus

subequal in length. Prothorax broader than long, narrowed and constricted in front, strongly bisinuate

This is one of the commonest and most widely distributed Conotracheli in Central

America. It is easily recognizable by the oval, oblique, dark, bare patch immediately

before the apex of each elytron, this being bordered internally by an ochreous line; and

the oblique similarly-coloured line on each side of the disc of the prothorax, the two

lines not meeting in front and continued down the head and rostrum, and also extending

backwards on to the elytral humeri. ‘The mesosternum is flattened between the coxe.

The femora are bidentate. The tarsal claws have a short tooth. The rostrum is

exceedingly stout, short, arcuate, rugulose and carinate, and very similarly formed in

the two sexes. ‘The fifth ventral segment is depressed or foveate on each side in both

male and female.

Fahreus ! also gives “ North America” as a locality, but the insect is not mentioned

by Leconte, and probably does not extend north of Mexico.

62. Conotrachelus divirgatus, sp.n. (Tab. XIX. figg. 10, 10a, 2.)

Subovate, shining, rufo-piceous, the antenna, the apical half of the rostrum, the tibia, and tarsi ferruginous ;

the vestiture sparse, ochreous, condensed into a sharply-defined oblique line on each side ot the disc of the

prothorax, the two lines continued forwards on to the head and rostrum and there coalescent, and back-

wards on to the humeri of the elytra, the latter with a common, broad, curved, ochreous, subapical fascia,

which extends down the suture to the apex and nearly encloses an almost bare, oblique, apical patch on

each elytron, the clothing of the under surface whitish, the femora with an ochreous ring. Head densely

punctate, foveate between the eyes, finely carinate in front; rostrum moderately stout, thickened a little

Hab. Panama, David in Chiriqui (Champion).

Two specimens from Chiriqui, precisely similar. Smaller than C. guadrilineatus and

C. venustus, the dorsal vitte of the prothorax broader. The elytra are narrower

than in the first-named species, with the dorsal prominences much smaller, and the

ochreous apical spots are lateral. Compared with C. venustus, the elytra are duller, with

Two specimens, from the Pacific coast, the one assumed to be the male having

stouter legs than the other. A small, rather convex form, with relatively narrow

elytra, the interstices of the latter not wider than the strize and equally convex

throughout. It approaches C. lineatus.

dense, pale brown, slightly intermixed with white and dark brown, the dark brown scales condensed into

three vittz on the prothorax, an irregular, transverse, undulate fascia at about the middle of the elytra,

and a faint fascia towards the apex, the upper and under surfaces and the legs also clothed with short,

scattered, white, decumbent, fine sete, the femora obsoletely annulate. Head densely, finely punctate ;

rostrum nearly twice as long as the prothorax, moderately stout, curved beyond the middle, squamose and

densely rugulose, the apical portion bare and thickly punctate, the antenne inserted at about one-third

One pair, the female with the intermixed white scales more abundant than in the

male, the latter having the dark brown elytral markings more distinct. This insect

somewhat resembles C. dentiferus, Fahr. The tarsal claws are formed almost as in

the North-American C. jissunguis, Lec. The dense vestiture hides the surface-

subfasciate elytra, the alternate interstices of which are uninterruptedly costate and

set with short white bristles, the unidentate, annulate femora, the form of the tarsal

claws, &c., will separate C. candidus from most of its allies. C. adustus has similarly

shaped tarsal claws.

Eleven specimens, eight of which are from Chiriqui. In this species the elytra have

a common, broad space, extending from the base to beyond the middle, darker and

more sparsely squamose than the rest of their surface, and a conspicuous narrow white

patch at the base of the third interstice. It approaches C. semirufus, but is much

smaller, the rostrum is more dilated at the middle, the femora have a distinct outer

tooth, and the hind tibiz of the ¢ are not excavate at the tip.

The above description is mainly taken from a pair from Chiriqui. This species is

very like C. sinuaticollis, but it has the rostrum shorter and stouter, and rounded

at the sides when viewed from above; the prothorax rounded at the sides and

more coarsely punctate; the elytral coste less interrupted, the one nearest the

suture strongly sinuate posteriorly. C. dilatirostris, which also has a mesially

dilated rostrum, has the dorsal coste of the elytra much more prominent and more

interrupted.

136. Conotrachelus segregatus, sp. n.

Very like C. sinuatocostatus, but with the rostrum stouter, and similarly widened towards the middle; the

prothorax less coarsely punctate, not carinate; the elytra with the ridge nearest the suture more broadly

interrupted below the base and strongly sinuate posteriorly ; the femora each with a triangular tooth

and a minute prominence a little exterior to it; posterior tibie feebly sinuate within in both sexes.

Length 53-52, breadth 24-3 millim.

Hab. Nicaraeua, Chontales (Janson).

Two specimens. If I have correctly identified the sexes of this insect (the supposed

male having the rostrum more closely punctate at the apex), O. segregatus cannot be a

form of C. sinuatocostatus, the latter having the posterior tibie peculiarly formed in

the male.

Oblong, robust, shining, black, the antenne and the tips of the tarsi obscure ferruginous; the vestiture

rather coarse, fulvous and whitish intermixed, very sparse on the disc of the prothorax and on the under

surface, and closer elsewhere, becoming subfasciculate on the elytra, that on the prothorax condensed

into two small spots on each side of the disc and another at each hind angle, the femora with

a whitish ring. Head densely, rugosely punctate; rostrum exceedingly stout, not longer than the

prothorax, flattened at the base above, widened from a little beyond the middle to the apex, sculptured

Elytra oblong, subparallel in their basal half, broadly rounded at the apex, slightly constricted below the

shoulders; interruptedly seriate-punctate, the interstices dull, 3 with a series of four very stout, oblong,

granulate tubercles, and 5 and 7 with scattered smaller tubercles, the others with small conical

prominences. Beneath opaque, finely punctate. Mesosternum conically protuberant in front. Legs

very stout, short, rugose; femora clavate, acutely unidentate ; tibise broad, compressed, sinuate; tarsal

tibie. It is extremely like C. lewcostictus, Boh., from Colombia (the type of which I

have seen), having a similar dense, oblique, chalky-white fascia below the shoulders of

the elytra, but wanting the cluster of four small white spots on each side of the suture

towards the apex; the mesosternum, however, is conically protuberant (instead of

being deeply excavate) in front, the prominences on the elytra are more swollen, and

the sete are absent.

A common species in Central America. In fresh specimens the prothorax has an

almost complete white ring on the disc of the prothorax—a character not mentioned

by Boheman, and not visible in worn or dirty examples. The sculpture of the upper

surface is rather variable and cannot be properly seen till the scales are removed.

The dark median fascia of the elytra is usually distinct; the alternate interstices are

sometimes a little more raised than the others. I have seen the types of C. rubicun-

dulus and C. pilosellus, Boh., the former being abraded and the latter densely

squamose. C. ambiguus, Faust, from Venezuela, differs in having longer sete.

C. hispidus, Lec., from Georgia, is probably synonymous with the present species.

141. Conotrachelus hystricosus, sp.n. (Tab. XXI. figg. 3, 3a.)

Subovate, shining above, dull beneath, piceous, the antenne, the tip of the rostrum, the tibie in part, and

the tarsi ferruginous; thickly clothed with narrow, whitish and brown scales, those on the elytra

oblong-oval in shape, the whitish scales on the prothorax condensed into a curved line on each side of the

disc and a longitudinal one at the sides, each line being continued on to the base of the third and fifth

elytral interstices, the elytra also with two transverse, connected, narrow whitish fascize towards the apex

and indications of another below the base, the femora biannulate with white; the upper surface also set

with numerous long, erect, stout, blunt, intermixed whitish and black setw, a number of the latter being

clustered together at the middle of the third elytral interstice, the legs also setose. Head densely

punctate; rostrum stout, feebly curved, as long as, or a little longer than, the head and prothorax,

rugulosely punctate, the antenne inserted near the tip, Joints 3-7 of the funiculus transverse, 2 twice as

long as 1. Prothorax strongly transverse, rounded at the sides, a little narrowed in front, feebly

bisinuate at the base; finely punctate. Elytra subtriangular, rather convex, the humeri obliquely

truncated ; seriate-punctate, the interstices rugulose and somewhat convex. Intermediate coxe narrowly

separated. Mesosternum convexly protuberant in front. Ventral segments sparsely, finely punctate.

Femora clavate, finely unidentate. Tarsal claws each with a long, slender, curved tooth, the two teeth

almost meeting at their apex.

Length 23-24, breadth 13 millim.

Hab. Panama, Volcan de Chiriqui (Champion).

Five specimens. A small species, distinguishable by the long, erect, stout,

intermixed black and whitish sete on the upper surface (there being a cluster of black

setae at the middle of the third elytral interstice), the squamose, variegate, non-costate

elytra, the long, curved tooth of the tarsal claws, &c. It is more strongly setose than

C. rubicundulus, and the sete are stouter than in C. ambiguus.

142. Conotrachelus bicarinatus, sp.n. (Tab. XXI. figg. 4,4, 2.)

Subovate, opaque, black ; the elytra obscure ferruginous, with a broad subapical fascia and the space between

the first ridge and the suture black, the reddish colour extending to the sides of the meso- and

metasternum, the antenne and the legs in great part ferruginous ; the vestiture very fine and short, that

bare), ochreous or fulvous, intermixed with white, the prothorax with two oblique, dense, ochreous lines

on each side (the outer one reaching from the hind angle to beneath the anterior angle, the inner one

shorter and in a line with the third elytral interstice), the elytra with a dense, transverse, fulvous space

on the humeri in front and a similarly-coloured streak on the third interstice just below the base; the

clothing of the under surface very scattered, that of the legs mostly fulvous, the femora each biannulate

with white; the elytral coste and the legs also with very short, scattered, decumbent, white bristles.

Head rugulosely punctate; rostrum (¢) stout, curved, very little longer than the prothorax, bare,

5-carinate, the tip shining and thickly punctate, (2) a little longer, and with the tip smoother, the

disc, arcuately narrowing from a little below the subangular humeri, deeply sinuate in front, the sides

with a small subconical prominence below the base beneath; seriate-punctate, the interstices broad,

alutaceous, 3, 5, 7, and 9 sharply costate, the ridge on 5 interrupted below the base. Intermediate

Hab. Guatemata, San Gerénimo in Vera Paz (Champion).

One pair. A very peculiar species, recognizable by the sharply bicarinate prothorax,

with two oblique ochreous lines on each side, the conically protuberant mesosternum,

the short, broad elytra, with the second ridge only interrupted, &c. The rostrum,

head, disc of the prothorax, and a broad space down the suture and the subapical

fascia of the elytra are almost bare, the surface being dull and alutaceous.

Eleven specimens from the above-quoted localities in our region are referred to this

species, which, on account of the two longitudinal ridges on the anterior part of the |

prothorax, is placed next C. leucopheatus by Leconte. In some of them the smaller

outer femoral tooth is quite distinct (especially on the posterior pair), but in others it

is absent. he prothorax has two white lines on each side, these being continued on

to the base of the opposite elytral costa, where they become ochreous. The elytra

usually have the humeri and apex ferruginous; the alternate interstices are narrowly

costate, the dorsal ridges more or less interrupted, the first joining the fourth at the

apex; and the inflexed sides are usually armed with a small conical prominence a

little below the base. The mesosternum is protuberant in the middle in front. The

rostrum is rugulose and 6-carinate in both sexes. The posterior tibie of the male are

excavate and ciliate at the apex within, and strongly, abruptly unguiculate. The

tarsal claws have a short tooth. In worn or dirty examples the lines on the prothorax

are obsolete. I have seen the type of C. rubiginosus. Found on hickory, in the fruit

of which they deposit their eggs, according to Say.

144. Conotrachelus insularis, sp.n. (Tab. XXI. fige. 6, 6a, 2.)

Subovate, opaque, black, the elytra mottled with ferruginous along the anterior half of the disc and with a

large, irregular, similarly-coloured patch on the apical declivity, the legs in part and the antenne also

the reddish portion of the elytra, the prothorax with a long, slender, somewhat X-shaped, white mark

on each side, the elytra with a large pallid humeral patch connected inwards with the condensed oblique

fulvous streak at the base of the third interstice, the rest of their clothing greyish, that of the legs fulvous

the prothorax at the base excepted.

Hab. Mexico, Alvarado in Vera Cruz (Chevrolat 1), Jalapa (Hoge, Smith); Panama,

Volcan de Chiriqui (Champion).

Of this species we have received six specimens from Mexico and five from Panama,

varying from 34—54 millim. in length, some of them agreeing perfectly with the type.

The latter has a large greyish-white, common, discoidal patch on the elytra, this colour

extending in two of the Jalapa examples to nearly the whole of the upper surface, the

rest of the fine vestiture being more or less ferruginous. The obliquely truncated

elytral humeri are spiniform in some examples and rather obtuse in others; the

broadly interrupted dorsal costs, too, vary in development. The carinate prominence

on the middle of the disc of the prothorax is always conspicuous. The femora are

unidentate. The intermediate coxe are widely separated. ‘The mesosternum is broad,

Two specimens in our collection nearly agree with the somewhat immature type

communicated by Dr. Sjostedt, of the Stockholm Museum. This species is recognizable

by the fasciculate arrangement of the elytral vestiture, which is condensed into a

conspicnous yellowish or rusty-red patch within the humeri, there being a similarly-

coloured patch on the front of the head and a small spot at each hind angle of the

prothorax ; the somewhat abundant, short setosity; the comparatively broad, coarsely,

rugosely punctured, carinate prothorax, the base of which is feebly bisinuate; the

almost uninterrupted elytral coste; the widely separated intermediate coxe; the

slightly hollowed meso- and metasternum, the sides of the mesosternum not being

at all protuberant in front; the coarsely, sparsely punctate abdomen, &c. The first

Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion).

Seven specimens. ‘The very rugose, sharply carinate, transversely subquadrate pro-

thorax, the rusty-red frontal patch, the white or greyish-white fasciculate vestiture of

the elytra, the finely costate suture, the short rigid setosity, &c., distinguish C. rufifrons.

it bears a certain superficial resemblance to C. cwrulescens.

182. Conotrachelus planifrons, sp. u.

Qvate, dull, nigro-piceous, the antenne and the tips of the tarsi reddish; the vestiture rather close above and

very sparse beneath, rusty-red or fulvous, the elytra often slightly mottled with whitish, that on the front

of the head sometimes partly or wholly whitish, the femora faintly annulate, the anterior pair with a

- fulyous line along their basal half above ; the upper surface and legs also set with short, scattered, pallid,

semierect setee. Head densely punctate, the front transversely depressed, and sometimes with a short

median carina and a small prominence on each side of it; rostrum moderately stout, arcuate, about as

long as the prothorax, a little longer in the 2, shining, 5-carinate in both sexes, sparsely punctate at the

tip, the antenne inserted towards the apex, joint 2 of the funiculus a little longer than 1. Prothorax

transverse, abruptly narrowed and constricted in front, deeply bisinuate at the base, the sides crenulate ;

densely, rugulosely punctate, the narrow interspaces here and there obliquely raised or granulate, the disc

finely carinate and usually with four conspicuous prominences about the middle. Elytra subcordate,

about one-half wider than the prothorax, deeply sinuate in front; seriate-punctate, the interstices faintly

granulate, 3, 5, 7, and 9 costate, 10 also carinate at the base, the ridge on 3 sometimes depressed or

interrupted anteriorly. Intermediate coxe widely separated. Mesosternum smooth and concave, pro-

tuberant on each side in front. Metasternum short, deeply hollowed and smooth in the middle, the

cavity nearly reaching the apex in the 2. Ventral segments sparsely, coarsely punctate. Legs stout

and rugose; femora clavate, unidentate ; anterior tibie sinuate within ; tarsal claws with a short tooth.

Length 4-53, breadth 21-31 millim. (¢ @.)

Hab. Mexico, Teapa (H. H. Smith); Guatemaua, Volcan de Atitlan, Panzos (Cham-

pion); Nicaragua, Chontales (Janson); Costa Rica (Biolley, in Mus. Brit.); Panama,

Bugaba, Volcan de Chiriqui (Champion).

Many specimens. In two of those from Chiriqui the femora have a very small

additional prominence, and in another the tooth on the anterior pair is almost obsolete.

This insect is extremely like C. sguamifrons, but is readily separable by the excavate

meso- and metasternum, and the longer second joint of the funiculus. The less elongate

shape, the closer vestiture, the less rounded sides and finer sculpture of the prothorax,

&c., distinguish it from the nearly allied C. costiferus.

183. Conotrachelus leucocephalus, sp. n.

Very like C. planifrons, but with a dense whitish frontal patch (as in C’ verticalis); the rostrum of the ?

flattened down the middle (not carinate) ; the sete very short and inconspicuous.

Length 4-6, breadth 23-3}, millim. (6 Q.)

Hab. Mexico, Toxpam (Sallé); Guatemata, Cerro Zunil, Purula (Champion).

Four specimens from Mexico and four from Guatemala, those from the northern

localities having the vestiture more mottled than in the others. The frontal patch

sometimes has a rosy-red tinge. In the largest female, from Purula, the rostrum is

depressed down the middle and sharply bicarinate on each side.

184. Conotrachelus carinifrons, sp. n.

Subovate, moderately shining, black, usually more or less mottled with ferruginous ; the vestiture fine, close

above, very sparse beneath, rusty-red or fulvous, the prothorax with a condensed, bright, rusty-red,

oblique vitta on each side of the disc, the two vitte nearly meeting in front and extending backwards

on to the humeri, the head with a condensed rusty-red patch in front, the femora annulate, the anterior

pair with a fulvous line along their basal half above ; the upper surface and legs also set with numerous

short, semierect, pallid setw. Head densely punctate, transversely depressed, carinate, and feebly

binodose in front; rostrum stout, curved, as long as or longer than the head and prothorax, seriate-

punctate and tricarinate, sparsely punctured at the tip, the antenne inserted towards the apex, joints

1 and 2 of the funiculus equal in length. Prothorax transverse, abruptly narrowed and constricted in

front, moderately bisinuate at the base ; densely, rugulosely punctate, and sharply carinate anteriorly.

Elytra nearly twice as wide as the prothorax, narrowing from about the basal fourth, transversely

depressed a little below the base, the humeri rounded ; coarsely seriate-punctate, the interstices rugulose,

3, 5, 7, and 9 costate, the ridge on 3 depressed or interrupted anteriorly, 10 also costate at the base.

Intermediate coxe widely separated. Meso- and metasternum broadly hollowed down the middle, the

cavity punctate. Ventral segments very sparsely, coarsely punctate. Femora clavate, acutely unidentate.

Hab. Mexico, Tapachula in Chiapas (/ége); GUATEMALA, Panzos in Vera Paz

(Champion); Costa Rica (Pittier, in Mus. Brit.).

Eleven specimens, nine of which were found at Panzos. This species approaches

C. subtilis, but has a relatively narrower, less rugose, bivittate prothorax, &c. ‘The

oblique rusty-red vittee on the prothorax are very sharply defined in fresh examples,

the flanks of the latter being almost bare.

Conotrachelus costiferus, Ros. in Schénh. Gen. Cure. iv. p. 452°.

Hab. Mexico, Orizaba (Chevrolat1), Teapa (H. H. Smith), Tapachula (Hoge),

Yucatan (Mus. Brit.); Brivis Honpuras, Rio Hondo (Blancaneauz).

The type of the species, now before me, is abraded, and wants the fine, scattered,

intermixed fulvous and white vestiture, which is subfascicularly arranged on the

elytra, and the short, fine, pallid sete are also nearly all rubbed off. The transverse

dense whitish patch on the front of the head is usually divided down the centre by a

smooth raised line, and in the middle of each portion there is a small bare prominence.

The prothorax is coarsely, rugosely punctate, and the median carina running down the

anterior half is often dilated posteriorly into a smooth flattened space. The alternate

elytral interstices are uninterruptedly costate. The femora are unidentate and faintly

annulate, the anterior pair with a long fulvous streak at the base above. The rostral

canal is rather deep and smooth, reaching to the anterior portion of the metasternum.

The ventral segments are coarsely, closely punctate. The eight specimens seen vary

from 55-7 millim. in length, and 24-4 millim. in breadth.

186. Conotrachelus pluricostatus, sp. n.

Subovate, shining, black, slightly mottled rufo-piceous, the tip of the rostrum, the basal half of the antenne,

and the apices of the tarsi ferruginous ; the vestiture rather coarse, longer on the prothorax, moderately

close, brownish, and uniformly distributed, the femora not annulate. Head densely punctate, transversely

depressed and finely carinate in front ; rostrum rather slender, feebly curved, a little longer than the head

and prothorax, 5-carinate at the base, sparsely, finely punctate in its outer half, the antenne inserted

just before the middle, joints 1 and 2 of the funiculus elongate and subequal in length. Prothorax

transverse, rounded at the sides, narrowed and feebly constricted in front, moderately bisinuate at the

base; densely, rather finely punctate, the narrow intervening ruge becoming longitudinally confluent

towards the apex, the disc with a fine median carina. Elytra subtriangular, comparatively short, the

humeri rounded ; coarsely seriate-punctate, the interstices closely rugulose, 3, 5, 7, and 9 narrowly, very

finely costate, and the others also finely costate from about the basal third onwards. Meso- and meta-

flab. Panama, Bugaba (Champion).

One specimen. In the uniformly distributed brownish vestiture this species

resembles C. conicicollis and C. serpentinus*, but it has both the meso- and metasternum

rather deeply excavate down the middle, the elytral interstices are all finely costate

posteriorly, &c.

187. Conotrachelus nigricollis, sp.n. (Tab. XXI. figg. 27, 27 a.)

Subovate, black, opaque, the elytra shining (when denuded), the latter sometimes mottled with rufo-piceous

or entirely of that colour, the antennx, and the legs in part, ferruginous; the elytra and legs (the basal

half of the femora excepted) densely clothed with rather coarse, narrow, brownish scales, the rest of the

surface almost bare. Head densely, rugulosely punctate, transversely depressed in front; rostrum

moderately stout, arcuate, a little longer than the head and prothorax, dull, rugulose, and unicarinate,

thickly punctate and shining at the tip, the antenne inserted at about one-third from the apex, joint 2

of the funiculus slightly shorter than 1. Prothorax strongly transverse, abruptly narrowed and constricted

in front, feebly bisinuate at the base, the sides usually sinuate and anteriorly dentate; closely, finely

punctate, the disc binodose at about the middle and also at the apex. Elytra nearly twice the width of

the prothorax, comparatively skort, subparallel at the base, the humeri dentiform; coarsely seriate-

punctate, the interstices finely and densely rugulose, 3, 5, 7, and 9 sharply costate, the ridge on 3

interrupted or depressed below the base. Rostral canal broad and deep, reaching to about the middle

of the metasternum. Ventral segments very sparsely punctate. Legs short; femora strongly clavate,

acutely unidentate ; tarsal claws with a short tooth.

Length 3-34, breadth 14-2 millim. (¢?)

Hab. Mexico, San Andres Tuxtla (Sallé), Iguala, Jalapa (Hoge).

Four specimens. <A peculiar little form, with the elytra densely clothed with narrow

brownish scales, and the rest of the body almost bare and opaque; the prothorax

quadrinodose and closely punctate, and usually with the sides dentate; the shoulders

of the elytra dentiform; the legs short; and the rostral canal broad and deep. An

abraded female from Chiacam, Guatemala, probably belongs to the same species,

though it has the rostrum slender, longer, and almost smooth from near the base.

A male from Bugaba, Panama, too, seems to be also referable to C. nigricollis, this

insect having the vestiture and ground-colour of the elytra more mottled.

444 RHYNCHOPHORA.

In this insect the declivous mesosternum (which has been injured in the type by the

pin) is slightly depressed in the middle anteriorly and has a compressed prominence

on each side in front, these prominences representing the anterior portions of the acute

horseshoe-shaped ridge present in some very nearly allied forms belonging to the

genus Phyrdenus, Lec. ‘The upper surface of the body and the legs are densely

squamose and setose. The prothorax is canaliculate down the middle and feebly

trinodose on each side of the groove. The alternate elytral interstices are slightly

raised. The femora are unarmed. The tarsal claws have a short stout tooth. The

rostrum is gibbous at the base. C. (Cyphorhynchus) luridus, Kirsch, from Peru, is an

extremely closely allied form.

ZEPALIUS, gen. nov.

Rostrum moderately long, curved, the scrobes descending to the lower limit of the eyes, but not contiguous

beneath ; antenne inserted towards the apex of the rostrum in both sexes, the funiculus 7-jointed, rather

loosely articulated, the club oblong-ovate, nearly as long as the preceding five joints united, the sutures

distinct; eyes lateral, coarsely facetted ; prothorax with prominent ocular lobes, much narrower than the

elytra; scutellum rounded, moderately large; elytra with ten rows of punctures ; prosternum rather long,

with a deep rostral canal; anterior and intermediate coxe somewhat widely separated ; mesosternum ~

concave, with a compressed lamelliform prominence on each side in front of the coxe; metasternum

concave and declivous in the middle in front, the episterna rather broad; ventral segments 3 and 4

together about as long as 2, all the sutures distinct; legs elongate; femora dentate; tibize unguiculate at

the outer apical angle, sinuate within; tarsi with joint 3 bilobed, the claws obtusely dilated in their basal

half; body elongate, squamose.

A single species is referred to palius. It is closely related to Conotrachelus,

though very different in general facies. The mesosternal lamelle are very prominent

(being more produced anteriorly than in C. setosus), and the tarsal claws are obtusely

dilated at the base (less angularly widened than in (@. anthonomoides), these characters

distinguishing the insect from all the forms here included under that genus.

1. Aipalius chiriquensis, sp.n. (Tab. XXII. figg. 1, la, }, 2.)

Elongate, dull, black, the antenne and the tips of the tarsi reddish; somewhat thickly clothed with small

brown scales, the vestiture becoming denser (and in one specimen ferruginous) on a large patch on the

apical half of the elytra, the upper surface and legs with intermixed very short, blunt, semierect, setiform,

fuscous or whitish scales, the scutellum ochreo-squamose. Head closely, densely punctate, feebly foveate

between the eyes ; rostrum about as long as the head and prothorax, sulcate laterally, rugulosely punctate

to near the tip in the d, more shining and much smoother in the . Prothorax a little broader than

long, rather convex, rounded at the sides anteriorly, constricted and narrowed in front and slightly

narrowed behind, the base bisinuate; densely, finely punctate. Elytra rather elongate, about one-third

wider than the prothorax, parallel in their basal half, sinuate at the base ; seriate-punctate, the interstices

rugulose and granulate, 3, 5, and 7 somewhat raised, 3 and 5 sinuate. Beneath rather coarsely punctate.

Femora sharply unidentate.

AMUS.—ZATUS. 445

JEMUS, gen. nov.

Rostrum moderately stout, very feebly curved, the scrobes descending to the lower limit of the eyes, but well-

separated beneath, the eyes large, rounded, lateral, coarsely facetted ; antenne inserted towards the apex

of the rostrum, the funiculus 7-jointed, closely articulated, widening outwards, the club stout, oblong-

ovate, with deep sutures; prothorax much narrower than the elytra, with prominent ocular lobes ;

scutellum oblong, small; elytra with ten rows of punctures; prosternum short, deeply excavate in front

for the reception of the rostrum; anterior cox moderately, the intermediate cox widely, separated ;

mesosternum depressed and concave, the sides not raised in front; metasternal side-pieces narrow ;

ventral segments 1 and 2 connate, 3 and 4 short, together about as long as 5 and much shorter than 2 ;

legs elongate ; femora clavate, sharply dentate ; tibie truncate at the apex, the inner apical angle feebly

mucronate, the outer apical angle sharply unguiculate ; tarsi with joint 3 broadly bilobed, the claws simple

and divergent.

The single species from which the above characters are taken has somewhat the

facies of an Anchonomorpha of the group Hylobiina. It is, however, a true Cryptor-

rhynchid, and must be placed near Conotrachelus.

1. Abmus tuberosus, sp.n. (Tab. XXII. figg. 2, 2 a.)

Oblong, alutaceous, opaque, black, the knees and antennew reddish in one specimen; the elevations of the

upper surface clothed with decumbent, blackish, setiform scales, the head, the lateral prominences of

the prothorax, and the outer edge of the humeri with fulvous scales, the under surface and legs sparsely

squamose, the latter also shortly setulose. Head finely punctate; rostrum about as long as the prothorax,

shining, very finely, sparsely punctate; funiculus with the outer joints transverse, 2 shorter than 1.

Prothorax a little broader than long, abruptly narrowed from about the middle, the sides parallel behind,

the base bisinuate; finely punctate, the disc with two setigerous prominences at the middle, a smaller one

on each side near the outer margin, and two at the apex. LElytra considerably wider than the prothorax,

subparallel in their basal half, the humeri rounded ; seriate-punctate, the punctures oblong in shape and

not hidden by the vestiture, the dorsal interstices (the first excepted) each with a series of prominent,

oblong, widely scattered, setigerous tubercles. Beneath alutaceous, closely, finely punctate. Femora

bidentate, the cuter tooth small and placed at some distance from the larger one.

Length 34-53, breadth 14-23 millim.

Hab. Panama, Volcan de Chiriqui 2500-4000 feet (Champion).

Two specimens, differing greatly in size, their sex not ascertained. ‘The elevations

of the upper surface are very conspicuous, owing to the setiform scales being clustered

upon them, the scales becoming fulvous in colour on the lateral prominences of the

prothorax.

JEATUS, gen. nov.

Rostrum short, curved, the serobes descending, very narrowly separated beneath; antenne with the funiculus

7-jointed, closely articulated, 3-7 gradually widening, the club oblong-ovate, with distinct sutures ; head

This genus includes a few small Tropical-American forms which bear a remarkable

superficial resemblance to certain Oncorrhini of the group Anchonina, the peculiar dull

upper surface, the almost smooth, globose head, the somewhat depressed eyes, &c.,

being here reproduced amongst the Ithyporides. The prosternal ridges in these

insects extend beyond the anterior coxe, and are received between the sides of the

mesosternum and the hollowed inner portions of the intermediate coxe. I have seen

one or two unnamed S.-American species that probably belong to Hatus.

Nine specimens. The exceedingly coarse sculpture of the prothorax, with a smooth

dilated space down the middle, and the anteriorly constricted and depressed elytra,

The elytra have the dull glossy appearance of those of Oncorrhinus latipennis.

2. Matus rugicollis, sp. n.

Subovate, black, the tarsi and antenne reddish; opaque above, the elevated portions of the surface only

MICROHYUS.

Microhyus, Leconte, Proc. Am. Phil. Soc. xv. p. 237 (1876).

This genus, hitherto including a single species from the United States, is well

represented in our region. ‘The various forms are all very small and separable from

Conotrachelus by the simple claws. The funiculus is 7-jointed, the joints closely

articulated and becoming wider outwards. The rostral canal is open behind. The

mesosternum is hollowed between the widely separated intermediate coxa, and not

raised at the sides in front. ‘The metasternum is short, and longitudinally swollen

on each side between the intermediate and hind coxe, the episterna rather broad.

The scutellum is very minute or hidden. The femoraare unarmed. The upper surface

of the body and the legs are set with erect, clubbed or blunt sete, which are seriately

arranged down each of the alternate elytral interstices. The Central-American species

may be tabulated thus :—

Six specimens, five of which are from Senahu; another, from Cerro Zunil, may

belong here, but it has narrower strize and flatter elytral interstices. This very small

species may be recognized by its comparatively narrow form, the convex elytral

interstices, and the feebly bisinuate base of the prothorax. The sete are longer,

One specimen. This minute Cryptorrhynchid has a very different facies from the

typical species of the genus Microhyus, owing to its long, subcylindrical prothorax

and narrow elytra; but it is not very far removed from M. montanus. ‘The open

rostral canal separates it from Acalles and other “ Tylodides.”

JENESIAS, gen. nov.

Rostrum stout, very strongly curved, moderately long, the scrobes deep and descending at once to the lower

side, but not contiguous beneath; antenne with a 7-jointed, slender funiculus, the club ovate, stout,

apical angle; tarsi with joint 3 bilobed, the claws divergent, simple.

The three small species placed under #nesias have somewhat the facies of various

aberrant Zygopina, owing to their large, finely facetted, partially exposed eyes;

nevertheless the well-developed ocular lobes of the prothorax show that they are

more nearly related to Conotrachelus. In general appearance they superficially

resemble certain Barids. The species selected as typical, #4. tuberculirostris, has a

prominent tubercle at the apex of the rostrum beneath, this being absent in the

two others.

Ten specimens. Near G. eques, but smaller, with the prothorax bivittate and the

elytra trifasciate, the sternal side-pieces densely albo-squamose, the prothorax less

dilated at the sides and more finely granulate, the elytra narrowed towards the base,

the tibiz wanting the median pencils of fulvous hairs. T have not detected any sexual

marks of distinction in this or any other species of the genus. The example figured

We have received four specimens of this species. In one of them the two elytral

fascie are pure white, and there is a narrow, additional, transverse, white median

fascia on the prothorax, this latter becoming more distinct on the flanks. The

dentiform fold or prominence on each side of the metasternum in front of the

posterior coxe is very conspicuous. The tooth on the inner edge of each of the

tibia near the middle is sharp and, like the two others at the apex, preceded by

pencils of fulvous hairs.

developed ocular lobes; scutellum oval; elytra each with ten sharply-cut strie ; rostral canal deep, open

and very broad behind ; prosternal ridges extending across the deeply excavate, contiguous anterior coxe ;

intermediate coxee moderately, and the posterior coxe very widely, separated ; mesosternum very short ;

metasternum sharply plicate laterally between the coxe, the episterna narrow; ventral segments 2-4

short, 1 with the intercoxal portion widened out into a broad, flattened, laterally and posteriorly

margined plate ; femora unarmed, deeply sulcate beneath for the reception of the tibiew, the anterior pair

The single minute species from which the above characters are taken is nearly

related to Cleogonus, but is easily recognizable by the peculiarly shaped tibiz, the

lamellate first ventral segment, &c. In these forms the legs are so interlocked in

repose that it is difficult to open them, the tibie in Microcleogonus closely fitting

into the deeply sulcate femora.

The single species referred to this genus has almost exactly the facies of Cono-

trachelus serpentinus, Boh., but, following the system of Lacordaire, it must be included

amongst the “Sophrorhinides,” the rostral canal being long and deep, at least in the

female, and abruptly terminated behind.

Sect. CRYPTORRHYNCHIDES.

Sous-Tribu iv. Cryptorhynchides vrais, Lacordaire.

Under this section are included all the Cryptorrhynchids with the rostral canal

abruptly closed behind by the protuberant, deeply excavate mesosternum. ‘The latter

is usually semicircular or horseshoe-shaped in front, and projects more or less forwards,

but the excavation sometimes extends as far backwards as the posterior margin of the

intermediate coxe. The first division, the “ Tylodides,” are connected with the second,

the “Cryptorhynchides vrais,” by Tylodinus, in which the rather broad metathoracic

episterna are more or less fused with the metasternum. ‘The only recent paper on

the Tropical-American members of this group is that of Faust (Stett. ent. Zeit. 1896,

pp- 35-88) *. I follow Lacordaire in placing most of the apterous forms first, these

either wanting a scutellum or having the metathoracic episterna so narrow as to be

covered by the inflexed margins of the elytra. Metadupus, however, is winged, and has

a large scutellum and sharply defined, exposed episterna: it belongs to his Groupe IL.,

“« Cryptorhynchides vrais,’ and not to the Groupe L., ‘‘Tylodides” ; Ulosomus, too, is

here referred to the second group.

* In this paper, “ Reise von E. Simon in Venezuela,” forty species are enumerated, belonging to twenty-two

genera, eighteen of which are characterized as new. The types of nearly all of them have been kindly lent us

for examination by Dr. Heller, of the Dresden Museum.

middle of the rostrum, joint 2 of the funiculus as long as or longer than 1, 3-7 short, the club elongate-

ovate (7. nodulosus, &c.) or ovate; eyes somewhat reniform, widely separated; prothorax hollowed in

the middle or subtruncate at the base, the ocular lobes small; scutellum wanting or not visible ; elytra

connate, tuberculate ; mesosternum large and prominent, semicircularly emarginate in front; metasternum

very short; metathoracic episterna rather broad, short, and more or less fused with the metasternum ;

ventral segments 3 and 4 very short, together about as long as 2, 1 and 5 much longer, the first suture

curved ; femora feebly dentate or unarmed ; body apterous.

Tylodes nodulosus, Boh., is taken as the type of this genus, which also includes

various other Central-American species. These insects cannot be associated with

T. armadillo (Sahlb.), the type of Tylodes, which is without visible metathoracic

episterna, nor with Z. ganglionicus, Boh.*, in which the side-pieces are long and

sharply defined and the ventral segments 1-3 are subequal in length. Two groups of

species are included under Tylodinus, one with an elongate, and the other with an

ovate, antennal club. In TY. 16-¢uberculatus and T. canaliculatus the episterna are

fused with the metasternum, and the suture is either obliterated or only just traceable

in front. T. cavicrus has the tibie very peculiarly formed, but this character may

Hab. Guatemata, Las Mercedes, Pacific slope (Champion).

‘One specimen. In this insect the large lamelliform prominences on the elytra are

placed further forwards than in 7. 4-lamellatus, and the humeri are each armed with

a compressed tubercle, the elytra themselves being very little wider than the prothorax

at the base.

Hab. Guaremaa, Quiché Mountains 9000 feet (Champion).

One specimen. The subpentagonal, coarsely multituberculate elytra, the granulate,

anteriorly tubulate prothorax, &c., distinguish this species.

to the apex.

Length 4-5, breadth 2-2} millim. (¢d 2.)

Hab. Guatemata, Cerro Zunil 4000 feet (Champion).

Nine specimens. This species approaches 7. cavicrus, but the elytra are less

parallel and not granulate and have much smaller tubercles, the tibie are differently

formed, &c. ‘The individuals with a shortened fifth ventral segment are assumed to

be males.

8. Tylodinus leucozona, sp.n. (Lab. XXIII. figg. 3; 3 a, posterior tibia.)

Oblong-ovate, subopaque, black, the antenn and the tips of the tarsi ferruginous ; thickly squamose, the

468 RHYNCHOPHORA.

Three specimens. The angularly dilated intermediate and hind tibie, and the

angulate white subapical fascia of the elytra, readily distinguish 7. leucozona. In one

example the elytral fascia is interrupted, and in another the curved brownish streak

on each side of the disc of the prothorax encloses a cruciform fulvous patch.

9. Tylodinus cavicrus, sp.n. (Tab. XXIII. figg. 4, ¢; 4a, front leg.)

Oblong-ovate, narrow, slightly shining, black, the antenne and tarsi ferruginous; sparsely clothed with dark

prominences on the disc, the outer posterior one the largest. Femora unidentate. Anterior and

intermediate tibia bowed inwards at the apex, acutely dentate on the inner side beyond the middle, the

space between this and the tip being very deeply excavate.

Length 54, breadth 24 millim. (<.)

Hab. GUATEMALA, Quiché Mountains 7000-9000 feet (Champion).

One specimen. The peculiar form of the anterior and intermediate tibie is doubtless

a sexual character.

10. Tylodinus callosus, sp. n.

Oblong-ovate, rather narrow, shining, black, the antenne and the tips of the tarsi ferruginous; thickly clothed

with moderately coarse brownish scales, which become fulvous in colour at the sides of the prothorax

foveolate and sparsely granulate, each elytron with six oblong or oblique prominences arranged in a double

series on the disc, the posterior two large and transversely coalescent at the commencement of the

apical declivity, which is abruptly declivous. Legs rather long, the femora unarmed, the anterior tibix

strongly sinuate.

Length 33, breadth 14 millim.

Hab. Mexico, Jalapa (Smith).

One specimen, given us by Mr. H. F. Wickham. The subparallel, gibbous, laterally

compressed, nodulose elytra, with large transversely-confluent tubercles at the com-

mencement of the apical declivity, sufficiently distinguish 7. callosus. The short

metathoracic episterna are exposed as in the preceding species, otherwise the insect

might be placed in Acalles.

XENOSOMUS. 469

XENOSOMUS.

Xenosomus, Faust, Stett. ent. Zeit. 1896, pp. 44, 50.

Two species from within our limits agree in several respects with the type of this genus,

Acalles gonoderus, Chevr., from the island of Guadeloupe ; but they differ from it, and

from XY. chevrolati, Faust, from Venezuela, in having the eyes much more widely

separated, the antenne inserted towards the apex of the rostrum, the second joint

of the funiculus not longer than the first, and the femora unarmed. The ventral

segments 2-4 are subequal in length, 1 and 2 being subconnate in the Central-

American forms. The elytra are subrotundate, and at the base not wider than the

prothorax.

1. Xenosomus inflatus, sp.n. (Tab. XXIII. figg. 5, 5a, 2.)

Oblong-ovate, opaque, black, the antennw and tarsi reddish; densely clothed with brown scales, the upper

surface with a few scattered decumbent sete intermixed, the legs setulose. Head and rostrum densely,

rugulosely punctate, the antenne inserted towards the apex of the latter, joints 1 and 2 of the funiculus

subequal in length, 3-7 short, the club ovate. Prothorax broader than long, constricted and abruptly

narrowed in front and also narrowed behind, the anterior portion tubulate, the base almost straight ;

densely, very finely punctate, the disc depressed down the middle behind. LElytra not wider than the

prothorax at the base, somewhat globose, with the apex produced ; seriate-punctate and faintly granulate,

each elytron with numerous rounded prominences on the disc, these being scattered along the interstices

2-7, and becoming smaller towards the sides. Femora unarmed.

Length 54, breadth 3;45 millim. (<d.)

Hab. Guatemaa, San Gerdnimo (Champion).

One specimen. The subglobose, nodulose elytra, the transverse, strongly constricted

prothorax, the unarmed femora, and the rugose rostrum, separate X. inflatus from the

species of the allied genera.

2. Xenosomus turpis, sp. n. |

Oblong-ovate, subopaque, black, the antenne and tarsi ferruginous; somewhat thickly clothed with brown

scales, which become more condensed on the head, and also set with scattered, decumbent, blunt,

similarly-coloured setee. Head and rostrum densely, rugulosely punctate, the antenne inserted towards

the apex of the latter, joints 1 and 2 of the funiculus subequal in length, 3-7 short, the club ovate.

Prothorax a little broader than long, rapidly narrowing from the middle forwards and also slightly

narrowed behind, the base subtruncate; closely, finely punctate, the disc shallowly depressed down the

middle and also transversely depressed anteriorly. LElytra not wider than the prothorax at the base,

somewhat gibbous, subrotundate, with the apex produced ; seriate-punctate and sparsely granulate, the

interstices on the disc here and there nodose, the elevations at the commencement of the apical declivity

(on 2, 3, 4, and 6) placed in a transverse line. Femora unarmed.

Hab. Guatemaa, Cerro Zunil 4000 feet (Champion).

One specimen. Near X. inflatus, but larger; the prothorax less constricted in

front; the elytra less globose and more feebly nodose, the elevations at the commence-

ment of the apical declivity so arranged as to form a transverse series.

470 RHYNCHOPHORA.

GERSTAECKERIA, gen. nov.

Ventral segments 2-4 subequal in length, the sutures straight and deep; the femora unarmed; the other

characters as in Acalles.

Type, Acalles bifasciatus, Gerst.

Several North-American and Mexican species hitherto referred to Acalles differ

from it in having a short second ventral segment, separated from the first by a straight

deep suture, and they can no longer be included in the genus, if Orypterus, EHuxenus,

Euscepes, &c. are to be retained. These insects, all of moderate or large size, have

the prothorax rounded at the sides and densely punctured; the elytra oval, very

coarsely seriate-punctate ; the legs stout (especially in G. bifasciata) ; and the femora

unarmed. Gerstaeckeria will include Acalles porosus, Lec., and probably various other

forms from the Southern United States described by Leconte or Casey.

1. Gerstaeckeria bifasciata. (Tab. XXIII. figg. 6, 6 a.)

Acalles bifasciatus, Gerst. Stett. ent. Zeit. 1860, p. 8937.

Hab. Mexico! (Mus. Berol.) Zimapan in Hidalgo (Hége).

This species was found in numbers on Cactus by Ehrenberg, according to Gerstaecker,

and one of the specimens described by him has been given us by the authorities of the

Berlin Museum. It is larger and more robust than any of the allied forms; the legs

are very stout, and the third tarsal joint is scarcely wider than the second.

2. Gerstaeckeria cruciata, sp. n.

Oblong-ovate, dull, black, the antennz and tips of the tarsi rufo-piceous ; variegated above with coarse

ochreous, whitish, and fulvous scales, the light-coloured scales condensed into a few small scattered spots

on the prothorax, a short oblique streak below the humeri, and a common cruciform or T-shaped post-

median fascia on the elytra, the suberect, very short, stout, setiform scales clustered into dense, compact,

broad lines on each of the interstices, the legs squamose, the femora and tibie annulate. Head and

rostrum closely, rather coarsely punctate (feebly carinate in one specimen), the interocular space shallowly

grooved down the centre; antenne inserted near the middle of the rostrum, joints 1 and 2 of the

funiculus subequal in length, the club ovate. Prothorax transverse, convex, rounded at the sides,

narrowed and feebly constricted in front, truncate at the base; coarsely, densely punctate. Elytra

ovate, at the base slightly wider than the prothorax; coarsely seriate-punctate, the interstices rather

broad, feebly convex, and closely punctate. “Ventral segments coarsely, closely punctate. Legs short

and stout, the femora unarmed.

Length 6-63, breadth 3-3} millim.

Hab. Mexico, Toxpam in Vera Cruz (Sallé), Mexico city (Hage).

Three specimens. Very like G. bifasciata, but smaller, the legs not nearly so stout,

the third tarsal joint much wider than the second, the post-median fascia of the elytra

not interrupted at the suture, &c. Acalles porosus, Lec., from Colorado, is another

very similar form.

GERSTAECKERIA. AT1

3. Gerstaeckeria leseleuci, sp. n.

Acalles leseleuci, Jekel, in litt.

Oblong-ovate, moderately shining, black, the antenne and the tips of the tarsi ferruginous ; variegated above

with a sparse clothing of coarse, ochreous, whitish, and blackish scales, the light-coloured scales condensed

into a short oblique streak below the humeri and a common cruciform post-median patch on the elytra,

the intermixed, suberect, setiform scales clustered into dense compact lines on the interstices, the under

surface and legs sparsely squamose. Head and base of the rostrum closely, and the rest of the latter

sparsely, punctate, the eyes large and not very widely separated; antenne inserted a little behind the

middle of the rostrum, joints 1 and 2 of the funiculus subequal in length, the club ovate. Prothorax

transverse, convex, rounded at the sides, narrowed and feebly constricted in front, truncate at the base ;

coarsely, densely punctate, and with a short median carina. Elytra ovate, at the base not wider than

the prothorax; very coarsely seriate-punctate, the interstices narrow, somewhat convex, sparsely

punctate. Ventral segments coarsely, closely punctate. Legs short and stout, the femora unarmed, the

tibiee sinuous within, the posterior pair mucronate at the inner apical angle ; tarsal claws minute.

Length 5, breadth 22-23 millim.

Hab. Mexico, Vera Cruz (Mus. Brit.), Juquila in Oaxaca (Sal/é).

Two specimens. Very like G. cruciata, but with the eyes more approximate, the

prothorax carinate, the seriate punctures on the elytra large and foveiform (the

interstices in consequence narrower), and the tarsal claws smaller. Acalles carinatus,

Lec., is probably a nearly allied form.

4. Gerstaeckeria lacti, sp. n. (Tab. XXIII. fig. 7.)

Acailes lacti *, Pilate, in litt.

Oblong-ovate, slightly shining, black, the antenne ferruginous ; clothed with scattered ochreous scales, the

head with a dense, rounded, whitish patch on the vertex, the elytra with an interrupted oblique streak

of coarse white scales at the sides below the base and a common, transverse, subcruciform, white fascia

surface coarse and mostly whitish, the tibie annulate with brown. Head closely punctate, slightiy

sulcate between the large eyes ; rostrum sparsely punctate, the punctures very coarse at the base, sulcate

in front of the eyes, the antennz inserted a little behind the middle, joints 1 and 2 of the funiculus equal

in length. Prothorax transverse, convex, rounded at the sides, narrowed and feebly constricted in front ;

very coarsely, confluently punctate, and also carinate anteriorly. Elytra oblong-ovate, not wider at the

pase than the prothorax; coarsely seriato-foveolate, the interstices narrow, rugosely punctate, and

here and there confluent. Ventral segments coarsely, closely punctate. Legs very stout, the femora

unarmed.

Length 8, breadth 32 millim.

Hab. Mexico, Campeche in Yucatan (Pilate, in Mus. Brit.).

One worn specimen. Larger and more elongate than G. leseleuct (of which it may

be an extreme form), with the sculpture of the prothorax and elytra exceedingly

coarse, the interstices of the latter being here and there confluent, the head with a

whitish patch on the vertex. The elytral markings are similar to those of G. leseleuct

and G. cruciata.

Acalles mutillarius, Gerst. Stett. ent. Zeit. 1860, p. 392°.

Hab. Mexico! (Mus. Berol.).

A very remarkable species, perhaps mimicking a J/utilla, densely squamose and

setose, the vestiture yellowish-white, except that the elytra have a very broad, common,

angulated, black fascia below the base (extending to beyond the middle), and a large,

This genus—the type of which is A. apicalis, Boh., from Cuba—includes a large

number of Palearctic forms, and it is also well-represented in several of the Atlantic

islands, the Hawaiian Is., New Zealand, &c. The various species from Central America

now added differ a good deal inter se, but as they do not exhibit any definite structural

peculiarities, they can remain for the present under Acalles. In all of them the pro-

thorax is truncate or hollowed in the middle at the base ; the scutellum is invisible; the

mesosternum is prominent, and semicircularly emarginate in front ; the metasternum is

very short ; and the metathoracic episterna are almost or quite covered by the inflexed

margins of the elytra. The second ventral segment is often more or less connate with

the first, and as long as or longer than the third and fourth united, these latter being

sometimes very short *. The tarsal claws are minute and narrowly separated in the

smaller forms. A. rugirostris has the antenne inserted towards the tip.

EURHOPTUS.

Eurhoptus, Leconte, Proc. Am. Phil. Soc. xv. p. 245 (1876).

Several Central-American species are referred to this genus, which is very closely

related to Acalles. These insects have the ventral segments 2-4 very short, 1 and 2

subconnate, and 1 usually excavate or with two very large smooth fovee *; the elytra

oval and connate; the scutellum not visible; the metasternum very short, without

visible episterna; and the tarsal claws very small and subapproximate. ‘The femora

are sometimes toothed, and the tibie in & costatus and “. levipennis are much

widened. The presence of a large depression or fovee on the first ventral segment is

probably a character common to both sexes: in one species (£. caviventris) the fovewe

are limited externally by a dense cluster of coarse ochreous scales, and in another

(E. alticola) they are only just traceable. The various forms may be grouped

thus :-—

Elliptic, shining, bronze-black, the antenne and tarsi ferruginous ; thickly clothed with rather coarse pale

brownish scales, except upon a transverse space below the base of the elytra and on the apical declivity

Hab. Guatemaua, Cerro Zunil, San Gerénimo (Champion).

Two specimens. A very peculiar form. The dense cluster of coarse ochreous scales

on each side of the first ventral segment is perhaps a male character; the central

excavation is doubtless common to both sexes.

The few described species of this genus are from the Antilles, Colombia, and Chile.

The Central-American form now added is nearly related to the type, L. solitarius, Boh.,

from the island of Guadeloupe, an insect that has also been recorded from Cape

Jupiter, Florida.

1. Lembodes trux, sp.n. (Tab. XXIII. fige, 24, 24 a.)

Elongate, narrow, parallel-sided, nigro-piceous, the antenn ferruginous; densely clothed with pale brownish

agglutinated scales, the elytra with a broad, common, cinereous patch extending down the apical half,

the upper surface also set with very coarse, clubbed, suberect, scattered sete, these becoming more

numerous along the anterior margin of the prothorax, and clustered into two fascicles on its disc, the legs

annulate and coarsely setose. Head and rostrum rugulosely punctate, the latter faintly carinate, the

eyes small; antenne inserted behind the middle of the rostrum, joint 1 of the funiculus elongate, 2 very

short, not much longer than 3, 3-7 transverse. Prothorax longer than broad, feebly constricted a little

before the middle, truncate at the base, arcuately projecting over the head in front ; closely punctate.

LEMBODES.—ULOSOMINUS. 483

Elytra barely twice the length of the prothorax, and of about the same width to a little beyond th

middle, broadly produced at the apex, the humeri rectangular; coarsely seriate-punctate, the interstice

narrow, the alternate ones apparently a little raised on the disc. Legs stout, the tarsi included, the

femora unarmed.

Length 31, breadth 14 millim.

Hab, Guaremata, San Gerénimo (Champion).

Two specimens. This curious insect may be easily recognized by its elongate,

parallel-sided form, the long prothorax, and rectangular humeri, the entire surface

coated with agglutinated scales, hiding the sculpture.

ULOSOMINUS, gen. nov.

Antenne with the funiculus 6-jointed, the club ovate; eyes small, very widely separated ; scutellum extremely

minute or invisible; metathoracic episterna hidden, or at most very narrowly exposed ; ventral segment 2

nearly as long as 3 and 4 united, the suture between 1 and 2 slightly arched; femora unarmed ; body

squamose and setose.

This genus includes several small species from within our limits, and the various

South-American and Antillean forms referred to Euscepes by Chevrolat and Faust

probably belong here. It is very closely related to Ulosomus (type U. erinaceus, Boh.),

which, however, has a conspicuous, transverse scutellum, narrowly exposed metathoracic

episterna, and the ventral segments 2-4 subequal in length. Huscepes, as stated below,

has a 7-jointed funiculus, Lacordaire incorrectly giving the number of joints as six.

1. Ulosominus quadrifasciculatus, sp. n. (Tab. XXIII. figg. 25, 254, 4.)

Oblong-ovate, narrow, piceous, the elytra rufo-piceous, the rostrum and antenne more or less ferruginous ;

densely clothed with small brown scales intermixed with similarly-coloured, very long, stout, erect, clubbed

setee, which are clustered into four fascicles on the elytra (two on the third interstice of each elytron), two on

the disc of the prothorax and two at its apex. Head densely punctate, the eyes small; rostrum rugulose

at the base, and sparsely, finely punctate towards the apex, longer and smoother inthe 9. Prothorax a

little broader than long, constricted and narrowed in front, the anterior portion somewhat tubulate, the

apex rounded; densely, finely punctate. Hlytra about one-half wider than the prothorax, moderately

convex, parallel in their basal half and rapidly narrowed behind, broadly produced at the apex, the humeri

obtuse, oblique in front; coarsely punctate-striate, the punctures subquadrate and closely placed, the

interstices narrow and rather convex, 3 a little broader and more raised than the others, 1, 3, 5, and 7

setigerous. Beneath closely, finely punctate. Legs rather long, moderately slender, the femora unarmed,

Length 22-3,1,, breadth 144,-14 millim. (¢ 2.)

Hab. Panama, Volean de Chiriqui 2500-4000 feet (Champion).

Five specimens. The very long, erect, stout, clubbed sete, which are clustered into

four dense fascicles on the disc of the elytra, sufficiently distinguish this insect. ‘The

sculpture is in great part hidden by the dense vestiture.

2. Ulosominus zunilensis, sp. n. |

Oblong-ovate, narrow, piceous, slightly mottled with black, the rostrum, antenne, and legs more or less

ferruginous; thickly clothed with small whitish and ochreous scales intermixed with erect, stout,

but with the elytra a little less produced at the apex, the sete shorter.

8. Ulosominus nanus, sp. n.

Oblong-ovate, narrow, rufo-piceous, the antenne and rostrum ferruginous, clothed with small ochreous scales

intermixed with coarse, erect, clubbed sete, these latter arranged in an irregular series down each of the

elytral interstices 1,3,5,and 7. Prothorax transverse, constricted and narrowed in front, densely punctate.

Elytra a little wider than the prothorax, subparallel in their basal half; coarsely seriate-punctate, the

punctures subquadrate, the interstices narrow. Legs rather stout, the femora unarmed.

and the oblong-ovate, slightly wider elytra. The intermediate coxe are widely

separated, and the prominent mesosternum is short and broad. The ventral segments

1 and 2 are connate at the middle.

5. Ulosominus triseriatus, sp.n. (Tab. XXIII. fig. 26.)

Oblong-ovate, narrow, rufo-piceous, the antenne ferruginous ; thickly clothed with small brownish scales,

intermixed with erect, clubbed sete, these latter becoming very long on the anterior part of the prothorax

and also towards the apex of the elytra, the sete short and arranged in a close series along the interstices

3, 5, and 7, and on the apical half of 1. Head and base of the rostrum densely, the rest of the latter

One worn specimen. ‘The short, inconspicuous sete show a tendency to form

fascicles on the prothorax and on the basal part of the elytra.

PSEUDOMOPSIS, gen. nov.

Eyes large and more or less approximate; rostrum slightly dilated at the base, the antenne inserted at or

behind the middle, the funiculus 7-jointed; prothorax transverse, conical, or a little dilated at the sides,

_ bisinuate at the base; scutellum small or wanting; elytra convex, wider than the prothorax, subtriangular,

and often laterally compressed, with ten rows of punctures, the humeri rounded ; mesosternum prominent,

arcuate-emarginate in front ; metasternum short, the episterna not visible; ventral segments 2—4 subequal

in length; femora dentate or unarmed, more or less sulcate beneath; tarsal claws small, subconnate or

narrowly separated at the base; body rhomboidal or subovate, squamose and often setulose.

Under this genus are placed various small species that are nearly related to

Pseudomus, from which they differ in having the elytra relatively broader at the base

(the sides not forming a continuous outline with those of the prothorax, as in

P. notatus, P. fistulosus, &c.), the rostrum less cylindrical, the body densely squamose,

&c. The humeri are more rounded than in Oxypterus, and setigerous elevations on the

prothorax and elytra are rarely present. The sexual differences in the sculpture of

the rostrum are very marked in P. dicristatus, and in the female of that species the

antenne are inserted near the base. The typical species of Pseudomus have the

general facies of a Cleogonus; they are all from the Antilles or the Southern United

States.

P. inflatus, Lec.*, from Florida, belongs to Pseudomopsis.

1. Oxypterus denticollis, sp.n. (Tab. XXIV. figg. 4, 4a.)

Subovate, shining, black, the antennz and the tips of the tarsi reddish ; densely squamose, the scales on the

head, along the middle of the prothorax, and at the base of the elytral suture, fulvous, becoming blackish-

brown at the sides and base of the prothorax, those on the elytra almost entirely blackish-brown, except

upon the very large, sharply-defined, brown or brownish-white patch extending down the apical declivity

to the tip, the elytra with a few blackish, semierect, setiform scales on the dorsal prominences; the

scales on the legs pale brown, the femora annulate with darker brown, greyish at the base. Head closely

punctate, the eyes rather narrowly separated ; rostrum closely punctate and subcarinate, bare in its

outer half, the antenne inserted a little behind the middle, joints 1 and 2 of the funiculus equal in

length, the club oblong-ovate. Prothorax much broader than long, abruptly narrowed and strongly

constricted in front and the sides nodose immediately behind this, dilated at the base, the base itself

deeply bisinuate, with the median lobe much produced; closely punctate, gibbous and binodose

at the middle, and also feebly binodose at the apex. Elytra very much wider than the prothorax,

gibbous, subtriangular, produced at the apex, the humeri swollen and laterally prominent, oblique in

front; coarsely seriate-punctate, each elytron with the second interstice raised and setose for a short

distance at about the middle and with some other small scattered setigerous prominences nearer the base.

Beneath closely punctate. Legs short and stout; femora dentate ; tarsal claws very small, contiguous

at the base.

Length 5-54, breadth 3-33 millim.

Hab. Mexico (Mus. Brit.), Jalapa (Hoge).

Two specimens, varying in the colour of the scales on the apical declivity. The

very short prothorax, with obtusely dentate, trisinuate sides, a binodose dorsal hump,

and produced median lobe, and the broad, subtriangular, gibbous elytra, with a very

large pale apical patch, readily distinguish this curious insect.

9. Oxypterus torvidus.

Oxypterus torvidus, Faust, Stett. ent. Zeit. 1896, p. 40°.

Hab. Panama, David (Champion).—Venezve.a, San Esteban *.

One specimen, agreeing perfectly with the type.

3, Oxypterus fasciculosus, sp. n. (Tab. XXIV. figg. 5, 5a.)

Subovate, convex, black, the antenne and the tips of the tarsi ferruginous ; densely clothed with cinereous or

pale brownish-ochreous scales, the prothorax and a large triangular space on the basal half of the elytra

mottled with brown, the elytra with a rather large oblong scutellar patch and a transverse or curved

streak on each side of this at the base whitish or ochreous, the upper surface also set with very short,

stout, blunt, erect, scattered sete ; the prothoracic and elytral elevations each with a fascicle of longer

ochreous, ferruginous, or dark brown sete, the front of the head also bifasciculate; the legs densely

squamose and setose. Head rugulosely punctate, shallowly sulcate between the eyes; rostrum with a

few very fine scattered punctures, the antenne inserted a little behind the middle, joints 1 and 2 of the

funiculus subequal in length. Prothorax transverse, subquadrate, very abruptly narrowed and constricted

in front; closely punctate, with four setigerous prominences placed in a transverse series a little before

the middle and two others at the apex. Elytra subtriangular; coarsely seriate-punctate, the interstices

rugulose, 2 with three and 4 with two setigerous scattered prominences on the basal half. Legs rather

stout, the femora dentate.

Length 34-5, breadth 2-24 millim.

Hab. Mexico, Toxpam (Sallé), Atoyac in Vera Cruz (H. H. Smith), Tapachula

(Hoge); GuatemaLa, Paraiso, Las Mercedes, El Reposo, Zapote, San Gerénimo,

Senahu, Panzos (Champion); Nicaragua, Chontales (Janson).

Fifteen specimens. This is a northern form of O. torvidus, inhabiting both the

Atlantic and Pacific slopes, with a broader scutellar patch, and a less elongate and less

conspicuous setigerous elevation at the commencement of the apical declivity of the

elytra. It also has the elytra a little broader and more convex. The dense vestiture

varies in colour.

4, Oxypterus asper. (Tab. XXIV. figg. 6, 6a.)

Cryptorhynchus asper, Boh. in Schonh. Gen. Cure. iv. p. 128°.

Hab. Guarrmaua, Senahu, San Juan, and Teleman in Vera Paz (Champion) ; PANAMA,

Bugaba (Champion).— Braziu!.

Found in plenty at Bugaba. This is a close ally of O. torvidus and O. fasciculosus,

but differs from both in wanting the pale scutellar patch on the elytra, and in having

the elytra themselves more gradually narrowed posteriorly. The oblique whitish line

at the middle of the base of each elytron isconspicuous. There is no visible scutellum.

The type has been communicated by Dr. Sjéstedt for comparison. A specimen from

Bugaba is figured.

5. Oxypterus fausti, sp.n. (Tab. XXIV. figg. 7, 7a.)

Oblong-ovate, narrow, black (the humeri and a subapical fascia, and the legs in part, sometimes ferruginous), the

antenne more or less ferruginous ; thickly clothed with coarse ochreous and blackish or brown scales, the

dark scales on the elytra not extending on to the apical declivity, the prothorax with a V-shaped ochreous

mark on the disc, the vestiture of the head dense and sometimes white; the upper surface also set with

scattered, coarse, semierect scales and the elevations each with a cluster of coarse setw. Head closely

punctate; rostrum rugulose and subcarinate at the base, and very sparsely, finely punctate thence to the

tip ; eyes narrowly separated ; joints 1 and 2 of the funiculus subequal in length. Prothorax broader

than long, convex, narrowed and feebly constricted in front, deeply bisinuate at the base; closely, rather

coarsely punctate, binodose on the disc before the middle, and with a projecting cluster of sete on each

side and two others at the apex. Elytra about one-half wider than the prothorax, convex, elongate-

triangular ; coarsely seriate-punctate, the punctures distant from one another, the interstices rugulose,

2 and 4 each with two or three scattered setigerous prominences. Legs long, the femora feebly

clavate and obsoletely dentate. :

Length 34-5, breadth 14-27, millim.

OXYPTERUS. 493

Hab. Mexico, Teapa (H. H. Smith); Guaremata, Senahu and San Juan in Vera Paz

(Champion).

Five specimens. The narrow, elongate shape, the V-shaped mark on the disc of the

prothorax, the coarse ochreous scales on the apical declivity of the elytra, &c.,

sufficiently distinguish O. faustz.

6. Oxypterus terminatus, sp.n. (Tab. XXIV. figg. 8, 8 a.)

Oblong-ovate, narrow, black, the antenna ferruginous, the elytra slightly mottled with rufo-piceous ; clothed

with small brownish scales, intermixed with coarse, suberect, black scales, the latter condensed into two

interrupted lines along the disc of the prothorax and several scattered fascicles on the second and fourth

elytral interstices; the elytra with a broad, sharply-defined, dense patch of small ochreous scales

extending the whole length of the apical declivity, and continued narrowly up the suture to the base,

and a curved ochreous and whitish streak extending inwards from the humeri, their surface also set with

scattered, long, clubbed, rather slender sete ; the prothorax with a small ochreous spot at the base; the

vestiture of the legs and under surface whitish or ochreous. Head closely punctate; rostrum rugulose

and carinate at the base, and sparsely, finely punctate thence to the apex; eyes somewhat distant ;

joints 1 and 2 of the funiculus subequal in length. Prothorax transverse, convex, abruptly narrowed and

constricted in front; closely, rather coarsely punctate, binodose on the disc before the middle and with

two clusters of sete at the apex. Elytra about one-half wider than the prothorax, somewhat gibbous,

elongate triangular, abruptly declivous posteriorly ; rather coarsely seriate-punctate, the punctures close

together and placed in strie on the disc, the interstices feebly convex, the black scales on 2 clustered into

a short streak at about the middle. Legs moderately long, the femora feebly clavate, the anterior pair

distinctly, and the others obsoletely, dentate.

Length 33-4, breadth 13-1,%, millim..

Hab. Mexico, Teapa (H. H. Smith); Guatemata, Cahabon (Champion).

Two specimens. Very like O. fausti, but with a sharply-defined, elongate, dense

patch of small ochreous scales at the apex, and the markings on the prothorax reduced

to a small spot at the base.

7. Oxypterus obliquus, sp. n. (Tab. XXIV. figs. 9, 9 a.)

Oblong-ovate, narrow, shining, nigro-piceous, the antenne ferruginous; somewhat thickly clothed with

intermixed ochreous and white scales, those on the head and the disc of the prothorax mostly ochreous ;

the white scales on the prothorax condensed into a small spot at the base and a line on the flanks, and

those on the elytra into an oblique line on the disc before the middle, a common v-shaped mark towards

the apex, and a patch at the sides; the prothorax with four fascicles of coarse ochreous or fuscous sete

placed in a transverse series across the middle (the outer two dentiform) and two others at the apex, the

feeble elevations on the elytra nigro-setose ; the femora annulate; the vestiture of the under surface

white. Head finely punctate, the eyes narrowly separated, joints 1 and 2 of the funiculus subequal in

length. Prothorax transverse, rather convex, narrowed and feebly constricted in front, closely, finely

punctate. Elytra about one-half wider than the prothorax, convex, elongate-triangular ; seriate-punctate,

the interstices rugulose and more or less convex, 2 with two feeble oblong setigerous prominences towards

the middle and 4 with a small prominence below the base. Legs long and slender, the femora feebly

clavate and also dentate.

Length 23-34, breadth 1-13 millim.

Hab. Guaremaa, Cerro Zunil, Purula (Champion); Panama, Volcan de Chiriqui,

494 RHYNCHOPHORA.

One specimen from each locality, the one from Purula abraded and showing that

the “elevations” of the upper surface are almost entirely due to the fasciculate

arrangement of the sete. This small species approaches the Venezuelan O. discretus,

Faust, but is much smaller and narrower, and has more slender legs, &c.

8. Oxypterus rubiginosus, sp.n. (Tab. XXIV. figg. 10, 10a.) |

Oblong-ovate, narrow, nigro-piceous, the rostrum ferruginous, the legs rufo-piceous; thickly clothed with

rusty-red and ochreous scales, the vestiture becoming much sparser at the sides and base of the elytra,

the ochreous scales condensed into three lines on the prothorax and two short, faint, oblique streaks on each

elytron, the feeble elevations on the latter densely clothed with coarse, erect, rusty-red, setiform scales ; the

vestiture of the under surface whitish. Head densely, the rostrum sparsely and very finely, punctate,

the eyes distant; joint 2 of the funiculus shorter than 1. Prothorax broader than long, somewhat

rounded at the sides, narrowed and feebly constricted in front; closely, finely punctate, feebly binodose

on the disc before the middle. Elytra more than one-half wider than the prothorax, convex, elongate-

triangular, the humeri swollen and laterally projecting ; seriate-punctate, the interstices rugulose, 2 with

two oblong setigerous prominences, one before and the other beyond the middle, and 4 with a smaller

prominence at the commencement of the apical declivity. Legs rather long, the femora narrow, dentate.

Length 3,-34, breadth 14 millim.

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

_ Two specimens. Smaller and narrower than the Venezuelan O. ochreatus, Faust,

the prothorax feebly binodose on the disc, the elytra with four very conspicuous

clusters of coarse, setiform scales near the suture at about the middle.

EUXENUS.

Euxenus, Faust, Stett. ent. Zeit. 1896, pp. 47, 50.

This genus, based upon two Tropical-American species, is nearly related to

Oxypterus, but differs from it in having less approximate eyes, sublinear, unarmed

femora, &c.

1. Kuxenus apicalis. (Tab. XXIV. figg. 11, 11 a.)

Euxenus apicalis, Faust, Stett. ent. Zeit. 1896, p. 48°.

Hab. Nicaragua, Chontales (Janson); Panama (Boucard; coll. Pascoe), Bugaba

(Champion).— VENEZUELA, San Esteban }.

Four specimens, all larger than the type. In this insect the elytra have the base

and a large apical patch densely clothed with brownish-white or ochreous scales, and

the suture is usually ochreous or ferruginous. The eyes are more approximate in

E. apicalis and the other Central-American species than in E. posticus, Faust, the

type of the genus Huxenus.

2. Euxenus subparallelus, sp. n.

Oblong-ovate, black ; thickly squamose, the head and prothorax brownish or ochreous, the prothorax with

three very faint paler vittew, the elytra brown, with the apical declivity and the suture for some distance

EUXENUS. . A495

from the base yellowish-white, and the base broadly and indeterminately ochreous, the legs and under

surface pale brown, the femora subannulate ; the upper surface also set with short, stout, clubbed setz,

which are blackish and crowded on the prothorax (except down the middle) and scattered on the elytra.

Head densely punctate; the eyes moderately distant; rostrum thickly punctate in the J, more sparsely

so inthe 9. Prothorax transverse, densely, rather coarsely punctate. Elytra considerably wider than

the prothorax, convex, subparallel in their basal half, the humeri obtuse, oblique in front; coarsely

seriate-punctate. Femora unarmed.

Length 44-53, breadth 2-23 millim. (¢ 9.)

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

Four specimens. Very near EZ. apicalis, but with the humeri less prominent, the

seriate punctures of the elytra closer and not so coarse, and the elytra themselves with

a yellowish-white, sharply defined, streak extending for a short distance down the

suture at the base, this not being connected with the apical patch as in E. apicalis.

3. Huxenus ovatipennis, sp. n. (Tab. XXIV. figg. 12, 12a.)

Extremely like Z. subparallelus, but with the elytra rounded at the sides, and at the base very little wider

than the prothorax, the ochreous or yellowish-white streak at the base of the suture a little less extended

posteriorly, the rest of the vestiture between the base and the apical declivity reddish-brown, becoming

darker posteriorly. Femora unarmed.

Length 44-43, breadth 22 millim. (d¢ 2.)

Hab. Guatemata, Las Mercedes and Dueiias, Pacific slope (Champion).

Five specimens. This insect is coloured almost exactly as in E. subparallelus, from

which, and from F. apicalis also, it differs in having the elytra rounded at the sides.

At first sight, Z. ovatipennis would appear to be an apterous form of £. subparallelus,

but this is probably not the case.

4, Buxenus rhombifer, sp. n. (Tab. XXIV. figg. 13, 13.)

? Collabismus sellatus, Schénh. Gen. Cure. viii. 1, p. 400 (nec Boh.) *.

Subovate, black, the antenne ferruginous; the prothorax clothed with coarse, intermixed brownish and black

scales, the black scales erect and setiform and clustered into two fascicles at the apex, and with a small

whitish v-shaped mark at the base; the elytra densely squamose, whitish or brownish-white, blackish

along the basal margin, with a common, transverse, dark brown or blackish, rhomboidal patch on the

dise, and also set with widely scattered, short, clubbed, erect, seriately arranged sete; the rest of the

vestiture ochreous or brownish, intermixed with white, the legs setulose. Head densely punctate, the

eyes large and not very widely separated; rostrum rugulose at the base and thickly punctate thence to

the apex. Prothorax transverse, densely punctate. Elytra nearly one-half wider than the prothorax,

convex, subtriangular, the humeri obtuse, oblique in front; coarsely seriate-punctate, the interstices

somewhat convex. Femora unarmed.

Length 4-44, breadth 14-2 millim.

Hab. Muxtco (Hogberg'), Teapa (H. H. Smith), Temax in N. Yucatan (Gaumer).

Two specimens. Readily recognizable by the densely squamose whitish elytra,

which have a large, common, blackish, rhomboidal patch on the disc. ‘This insect is

extremely like Collabismus sellatus, Boh., but the latter is larger, and has exposed

metathoracic episterna, a longer prothorax, more closely setose elytra, &c.

496 RHYNCHOPHORA.

SPILONOTUS, gen. nov.

Rostrum moderately stout, about as long as the head and prothorax, curved, depressed at the base, the antenne

inserted at or a little behind the middle, the funiculus 7-jointed, 1 and 2 elongate, the others short, the

club ovate, with distinct sutures; eyes large, narrowly separated; prothorax strongly transverse,

rounded at the sides, deeply bisinuate at the base, the ocular lobes feebly developed ; scutellum very

small; elytra a little wider than the prothorax, convex, parallel at the base, with ten rows of punctures,

the outer one short, the humeri rounded ; mesosternum prominent, raised, horseshoe-shaped ; metasternum

short, the episterna scarcely visible, except in front ; ventral segments 2-4 subequal in length, the sutures

almost straight; femora feebly clavate, unidentate, shallowly sulcate beneath ; body oblong-ovate,

convex, squamose.

The single species referred to this genus is nearly allied to Huscepes, Euxenus,

Oxypterus, &c., but cannot be included in any of them, as at present defined. The

very small scutellum, the almost hidden metathoracic episterna, &c., separate it from

Diaporesis and some other genera of Division I]. The intermediate coxe are more

approximate than in Gerstaeckeria.

1. Spilonotus ornatus, sp.n. (Tab. XXIV. figg. 14, 14 a.)

Black, the antenne and the tips of the tarsi more or less ferruginous ; thickly clothed with brown scales, the

elytra each with a transverse sharply-defined patch at the shoulder, as well as a common, oblong,

scutiform patch on the apical declivity, velvety-black, the humeral markings almost surrounded by a

fulvous line, the apical one preceded by a rather broad, curved, fulvous or ochreous fascia which extends

outwards to the fourth or fifth row of punctures, the upper surface also with a few widely scattered

ochreous or whitish scales, and the scutellum similarly coloured; the vestiture of the legs and under

surface reddish-brown, intermixed with whitish, the femora subannulate. Head densely, finely punctate ;.

rostrum rugosely punctate and carinate to near the middle, and minutely punctate thence to the apex, a

little longer and smoother in the 9. Prothorax narrowed and feebly constricted in front, densely

punctate. Elytra rapidly narrowing from about the middle; rather coarsely seriate-punctate, the

interstices flat, minutely punctulate. Beneath closely punctate. Legs moderately long, rather stout,

the femoral tooth triangular.

vength 5-64, breadth 22-3 millim. (¢ 2.)

Hab. Mexico, Jalapa (Hoge); GuatemMata, Senahu in Vera Paz, Cerro Zunil, San

Isidro (Champion); Panama, Volcan de Chiriqui (Champion).

Seventeen specimens, all but three from Cerro Zunil. In this insect the three

velvety-black spots on the elytra are very conspicuous, and the subapical one is

preceded by a broad, arcuate fulvous or ochreous fascia. The single example from

Panama has darker brown scales and the apical black patch less truncate in front. I

know of no other Cryptorrhynchid with similar markings.

| EUSCEPES.

Euscepes, Schonherr, Gen. Cure. vii. 1, p. 429 (1844) (nec Faust).

The type of this genus, £. porcellus, Boh. (= Acalles longulus, Lec.), is a common

insect in Central America, whence several other species are now added. Lacordaire

(Gen. Col. vii. p. 100) gives the funiculus as 6-jointed, but upon examining the type I

find that this is a mistake, and that the number of joints (7) was correctly noted by

EUSCEPES. 497

Schénherr. Euscepes is a very close ally of Euxenus, Faust, but differs from it in

having finely dentate femora. ‘The antenne have joints 2-7 of the funiculus closely

articulated, 2 shorter and narrower than 1. The ventral segments 2-4 are subequal in

length ; 2, however, is distinctly longer than 3 or 4 in E. porcellus. Cryptorhynchus

batate, Waterh., from Barbados, belongs to Huscepes.

A common species in Central America, some of our specimens agreeing perfectly

with the type from Puerto Rico, and with an example of Acalles longulus, Lec., from

Florida, sent me by Mr. Wickham. The elytra have a large, densely squamose,

brownish-ochreous apical patch, and the vestiture at the base is often similarly

coloured ; the seriate punctures are coarse and closely placed, the interstices narrow,

the alternate ones sometimes a little raised. The eyes are widely separated. The

femora are finely dentate. ‘The sete are short, coarse, and erect. Hu«enus posticus,

Faust, from Venezuela, is very like L. porcellus; but it is larger and broader, and has

the apical patch reduced to a subapical fascia and the femora unarmed.

9, Euscepes divisus, sp.n. (Tab. XXIV. figg. 16, 16 a.)

Oblong-ovate, black, the antennex ferruginous ; densely clothed with ochreous or brown scales; the prothorax

with numerous intermixed blackish setiform scales, the dise with an ochreous median line and a few

small scattered ochreous spots; the elytra with a very large, sharply-defined, brownish-white or ochreous

patch covering the apical declivity, limited anteriorly by an indeterminate curved blackish fascia,

and also set with very short, decumbent, inconspicuous sete; the vestiture of the under surface greyish

or brown. Head densely punctate, the eyes distant; rostrum rugulosely punctate, subcarinate, and

squamose to about the middle, and thickly punctate thence to the apex. Prothorax transverse, feebly

bisinuate at the base, densely punctate. Scutellum sometimes visible. Elytra about one-half wider than

the prothorax, subparallel towards the base, the humeri obtuse, obliquely truncate in front ; coarsely

seriate-punctate, the interstices rugulose and almost flat. Beneath densely punctate, Femora feebly

dentate.

Numerous examples. In this insect the sete of the elytra are very short and

inconspicuous, and the large whitish apical patch is limited anteriorly by an indeter-

minate curved blackish fascia. Most of the specimens have a few scales clustered

together in the minute scutellar cavity and a very small whitish spot on the disc of each

elytron. J. divisus is a close ally of £. porcellus, but it is much larger and less setose.

8. Euscepes longisetis, sp. n.

Oblong-ovate, black, the antenne ferruginous; thickly clothed with reddish-brown scales, which become

blackish towards the anterior limit of the very large ochreous patch covering the apical declivity ; the

prothorax closely, and the elytra sparsely, setose, the sete on the latter long and erect, the legs also

setose. Head densely punctate, the eyes widely separated; rostrum closely punctate. Prothorax

convex, a little broader than long, somewhat rounded at the sides, bisinuate at the base; closely punctate.

Elytra one-half wider than the prothorax, subparallel in their basal half, the humeri obtuse ; seriate-

punctate, the interstices almost flat. Beneath rather sparsely punctate. Femora feebly dentate.

One specimen. Very like £. porcellus, but with much longer sete on the elytra,

the seriate punctures rather fine. |

4. Kuscepes truncatipennis, sp.n. (Tab. XXIV. fig. 17.)

Oblong-ovate, shining, nigro-piceous, the antenne ferruginous; clothed with ochreous and brown scales, the

elytra with a dense, anteriorly dilated patch of intermixed, small, adpressed and broad, semierect, whitish

scales extending from the apex to near the middle, the sides and basal half also set with very short,

coarse, scattered, clubbed sete. Head closely punctate, the eyes moderately distant ; rostrum rugulosely

punctate and squamose at the base, the apical half thickly punctate in the ¢ and minutely punctate in

the 2. Prothorax a little broader than long, rounded at the sides, narrowed and slightly constricted in

front, and feebly bisinuate at the base; densely punctate. Elytra about one-third wider than the

prothorax, subparallel in their basal half, with the apices broadly produced and subtruncate ; very

coarsely seriate-punctate, the punctures subquadrate and closely placed, the interstices narrow and slightly

raised. First ventral segment very coarsely and closely, and the others sparsely and finely, punctate.

Legs rather long, the femora minutely dentate.

Length 33-4, breadth 13-14 millim. (¢ 9.)

Hab. Brirish Honpuras, Rio Hondo (Blancaneauz).

One pair, both specimens partially abraded. In this insect the elytra are broadly

produced at the apex, and the raised intermixed whitish scales on the apical declivity

minute scutellum.

OXY PTEROPSIS, gen. nov.

Rostrum stout, curved, triangularly dilated at the base, the antenne inserted behind the middle, the funiculus

7-jointed, the club ovate, with distinct sutures ; eyes large, narrowly separated; prothorax transverse,

bisinuate at the base, the ocular lobes feebly developed ; scutellum small; elytra much wider than the

prothorax, subtriangular, with ten rows of punctures ; mesosternum very prominent, arcuate-emarginate

in front; metasternum moderately long, the episterna extremely narrow or invisible; ventral segments

2-4 subequal in Jength ; femora clavate or sublinear, unarmed (the posterior pair in O. armatus with

a stout blunt tooth near the apex, perhaps peculiar to the ¢ ); tibiz compressed, strongly unguiculate at

the outer apical angle; tarsi with joint 3 broadly bilobed, the claws minute and approximate.

Type O. armatus.

‘The three species included under this genus are nearly related to Oaypterus,

Euxenus, and Euscepes; but as they agree in having two characters in common,

viz. a small conspicuous scutellum and unarmed femora (except the posterior pair

in O. armatus), it seems best to separate them. 0. latirostris has a broad apically

dilated rostrum, 0. armatus peculiarly-formed hind femora and tibie, and O.7 bipartitus

apically produced elytra.

1. Oxypteropsis armatus, sp.n. (Tab. XXIV. figg. 18; 18a, hind leg.)

Rather elongate, narrow, subfusiform, nigro-piceous, the legs and elytra rufo-piceous; densely clothed with

ochreous and brownish scales, the ochreous scales condensed into a well-defined median vitta on the

prothorax, the elytra with a transverse, subquadrate, subapical, white fascia, the upper surface also set

with scattered semierect sete, the legs setulose. Head densely punctate, the eyes large and narrowly

separated; joint 2 of the funiculus nearly as long as 1; rostrum closely, finely punctate, rugulosely

punctate and squamose at the base. Prothorax transverse, narrowed and constricted in front, rounded

at the sides anteriorly; densely punctate. Elytra elongate-triangular, considerably wider than the

prothorax, compressed at the sides posteriorly, the humeri obliquely and subangularly dilated; finely

punctate-striate, the interstices closely, minutely punctulate. Legs stout; femora clavate, the posterior

pair with a stout blunt tooth on the inner lower edge towards the apex, the others unarmed ; tibie

sinuate within, the posterior pair deeply, and the others more shallowly, excavate at the base.

Length 33, breadth 13 millim. (¢ ?)

Hab. Panama, Bugaba (Champion).

One specimen. The peculiar form of the posterior femora and tibiz is doubtless a

male character, as the femoral tooth is not in the usual position. The metasternum

is densely clothed with ochreous scales.

2. Oxypteropsis latirostris, sp.n. (Tab. XXIV. figg. 19, 19 a.)

Subovate, rather narrow, shining, nigro-piceous, the antenn# ferruginous ; thickly clothed with intermixed,

coarse, ochreous and white scales, the elytra variegated with black and with the white scales condensed

into a sharply-defined transverse subapical fascia (formed by a short line on each of the interstices 1-4),

a minute spot on the anterior part of the disc and another near the apex, the prothorax with two

fascicles of coarse, erect, setiform, intermixed fulvous and black scales on the disc. Head densely

punctate, the eyes very large and narrowly separated ; rostrum short and broad, dilated at the apex and

also a little widened at the base, thickly punctate, smooth and subcarinate down the middle; joint 2 of

the funiculus much shorter than 1. Prothorax transverse, abruptly narrowed and constricted in front,

feebly binodose on the disc anteriorly ; densely, finely punctate. Elytra convex, one-half wider than the

prothorax, subtriangular, the humeri rather prominent ; coarsely seriate-punctate, the interstices narrow,

rugulose, and rather convex, 2 broader, swollen, and setigerous at the commencement of the apical

declivity. Beneath rather coarsely punctate. Mesosternum very broad. Legs short and stout, the

femora unarmed.

Length 3, breadth 13 millim.

One specimen. This insect is very like Oxypterus capillatus, Faust, from Venezuela;

but it has a short, broad, apically dilated rostrum and a conspicuous squamigerous

scutellum, the elytra are more rapidly narrowed from the base and have the subapical

white fascia differently formed, the femora are unarmed, &c.

8. Oxypteropsis bipartitus, sp.n. (Tab. XXIV. figg. 20, 20a.)

Elongate-ovate, black, the antenn# ferruginous; clothed with small brown scales, with a few whitish or

ochreous scales intermixed, the elytra with a dense, anteriorly dilated, patch of whitish or ochreous

scales extending from the apex to near the middle and each with a minute whitish spot on the disc, the

upper surface also somewhat thickly set with short, semierect setee, the legs setulose. Head densely

punctate, the eyes large and narrowly separated ; rostrum very finely punctate, rugulosely punctured and

squamose at the base ; joint 2 of the funiculus much shorter than 1. Prothorax transverse, constricted

and narrowed in front ; densely punctate. Elytra much wider than the prothorax, subparallel in their

basal third, broadly and strongly produced at the apex, the humeri rounded ; coarsely seriate-punctate,

the interstices closely, minutely punctulate, 2 and 4 slightly raised posteriorly. Legs moderately stout,

the femora almost linear and unarmed.

Length 4-47, breadth 14-2 millim.

Hab. Guatemaa, Cerro Zunil 4000 feet (Champion).

Two specimens, probably male and female. This insect much resembles Euscepes

truncatipennis, but the femora are unarmed, the prothorax is shorter and has the sides

less rounded, the squamigerous scutellum is distinctly visible, and the elongate densely

squamose whitish or ochreous apical patch is without intermixed broad scales.

MICROXYPTERUS, gen. noy.

Rostrum curved, stout, triangularly dilated at the base, the antennse inserted a little behind the middle, the

funiculus 7-jointed, the club ovate, with distinct sutures; eyes large and not very widely separated ;

prothorax transverse, somewhat rounded at the sides, bisinuate at the base, the ocular lobes almost

obsolete; scutellum not visible; elytra convex, a little wider than the prothorax, ovate, laterally

compressed and attenuate at the apex, 10-striate, the humeri rounded; mesosternum very prominent,

arcuate-emarginate in front; metasternum moderately long, the episterna not visible; ventral segments

2-4 subequal in length ; femora feebly clavate and minutely dentate ; tibia narrow, unguiculate at the

outer apical angle; tarsi slender, joint 3 bilobed, the claws minute and approximate; body narrow,

squamose and setose.

Microxypterus includes two small species of peculiar facies, each having a large

space at the sides of the elytra sparsely squamose or almost bare. They approach

Oxypterus obliquus, but lack the prominent humeri; and the fasciculate vestiture of

the elytra is here replaced by a row of long, scattered, erect setae on each interstice,

The femoral tooth is narrow and minute. The humeri are less prominent than in

Pseudomopsis.

1. Microxypterus suturalis, sp.n. (Tab. XXIV. figg. 21, 21a.)

Oblong-ovate, narrow, shining, nigro-piceous, the antenna, the tarsi, and the apices of the tibie more or less

ferruginous, the elytra rufescent, with the sides darker ; the squamiform vestiture of the head ochreous,

that of the prothorax ochreous and brown intermixed, except upon the white median vitta; the elytra

w.th a posteriorly widened, dense, brownish-white sutural stripe, bordered externally by an interrupted

blackish line, the rest of the squamosity much finer, more scattered, and ochreous, the interstices each

with a row of long, fine, erect, scattered sete; the under surface and legs squamose, the latter also

setulose. Head densely punctate, the eyes large and rather narrowly separated; rostrum widened and

rugosely punctate at the base, and sparsely, finely punctate thence to the apex; joint 2 of the funiculus

shorter than 1. Prothorax transverse, convex, rounded at the sides, narrowed and slightly constricted

in front, feebly bisinuate at the base, without distinct ocular lobes; densely punctate. Elytra convex,

ovate, about one-third wider than the prothorax, compressed at the sides, rapidly narrowing from the

base; punctate-striate, the interstices punctulate and almost flat. Ventral segments closely punctate.

Length 3, breadth 11 millim.

Hab. Panama, Bugaba (Champion).

One specimen. The vestiture of the elytra exterior to the posteriorly-widened

sutural stripe is not sufficiently dense to hide the sculpture.

2. Microxypterus binotatus, sp.n. (Tab. XXIV. fig. 22.)

Oblong-ovate, narrow, shining, black or piceous, the antenna, rostrum, tibie, and tarsi more or less ferruginous,

the elytra rufo-piceous or ferruginous, with a large black patch on each side ; thickly clothed with

brownish-white or ochreous scales, the lateral patches of the elytra almost bare; the elytral interstices

each with a scattered series of long, erect, blunt sete, and the prothorax also shortly setose ; the legs

squamose and setose. Head densely punctate, the eyes large, but well-separated ; rostrum widened

at the base, rugulosely punctate and squamose to near the tip in the ¢, rugulose and carinate at the base,

and sparsely punctate towards the apex, in the 9 ; joint 2 of the funiculus a little shorter than 1.

Prothorax slightly broader than long, rounded at the sides, narrowed and feebly constricted in front,

bisinuate at the base; closely punctate. Elytra shaped and sculptured as in 0. suturalis.

Length 24-3, breadth 15-13 millim.

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

Three specimens. A fourth, from San Juan in Vera Paz, seems also to belong here ;

but it has the eyes larger and almost contiguous, and the anterior femora unarmed.

In this insect the elytra have a common, broad, densely squamose space running down

their entire length, extending outwards at the base, leaving a large almost bare patch

at the sides.

DERCYNUS, gen. nov.

Rostrum stout, curved, triangularly dilated at the base, the antenne inserted behind the middle, the funiculu

7-jointed, the club ovate, with distinct sutures ; eyes large, depressed, well-separated ; prothorax very

broad, transverse, bisinuate at the base, with feebly-developed ocular lobes ; scutellum not visible ; elytra

broad, much wider than the prothorax, with ten rows of punctures; mesosternum prominent, arcuate-

emarginate in front; metasternum very short, the episterna not visible; intercoxal process of the

abdomen broadly truncate in front ; ventral segments 2-4 equal in length, the sutures straight; femora

very stout, subclavate, deeply excavate before the apex, and also feebly dentate and sulcate beneath ;

tibis short, broad, dilated from near the base, unguiculate at the outer apical angle; tarsi short, stout,

joint 3 bilobed, 4 slender, the claws very minute and approximate ; body subovate, broad, densely

squamose.

The single species from which the above characters are taken is one of the numerous

Tropical-American forms nearly related to Acalles, but which cannot be included in

that genus. ‘The depressed eyes, the very stout, short legs, the minute, approximate

tarsal claws, the truncate intercoxal process of the abdomen, the broad form, &c.,

distinguish it from Oxypterus and other allied American genera. It is somewhat

remarkable that an insect with such stout legs should have the tarsal claws so minute,

1. Dercynus micronyx, sp.n. (Tab. XXIV. figg. 23, 23a, b.)

Subovate, broad, robust, black, the antenne in part ferruginous; densely clothed with coarse brown scales,

with a few whitish scales intermixed, the elytra with a more or less distinct oblong mark on the suture

below the base, an oblique line below the shoulders, and a common sinuate subapical fascia, whitish or

ochreous, the femora subannulate; the elytra also sparsely set with very short, stout, blunt, semierect

sete, which are more closely placed on the dorsal elevations. Head closely punctate, the eyes moderately

distant; joints 1 and 2 of the funiculus subequal in length; rostrum punctato-striate, carinate at the

base. Prothorax strongly transverse, rounded at the sides anteriorly, constricted and much narrowed in

front, deeply bisinuate at the base; closely punctate and also carinate. Elytra barely one-half wider

than the prothorax, somewhat flattened on the disc and abruptly declivous behind, subparallel to about

the middle, the sides subangularly dilated above the intermediate coxe, the apices broadly produced, the

humeri obliquely truncate in front; coarsely seriate-punctate, the interstices rugulose, 2, 4, and 6 here

and there raised. Beneath closely, finely punctate.

Length 43-5, breadth 23-24 millim,

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

Two specimens. The broad form, the short, stout legs, the subparallel elytra, with

the sides subangularly dilated before the middle and the apices broadly produced,

sufficiently distinguish D. micronyz.

Phymatophosus, Faust, Stett. ent. Zeit. 1896, pp. 54, 83.

Faust included Phymatophosus amongst the group “ Cryptorhynchides vrais” of

Lacordaire, and placed it next Apteromechus, but as the metathoracic episterna are

extremely narrow or not visible (when the scales are removed) the genus really belongs

to the “ Tylodides,” near Oxypterus, from which it differs in the small, laterally placed

eyes, the unarmed femora, the presence of a small scutellum, &c. The mesosternum

is very prominent and raised above the level of the metasternum, and its anterior

edge is feebly emarginate. The ventral segments 2-4 are equal in length. The

tarsal claws are very small, and narrowly separated or subconnate.

on the dorsal elevations of the elytra, the prothorax with four fascicles of erect ochreous sete placed

across the middle of the disc (the outer two small) and two at the apex ; the legs setulose. Head densely

punctate, depressed between and above the eyes; rostrum short and very stout, squamose to near the

tip, densely punctate and faintly carinate. Prothorax transverse, subconical, feebly constricted in front,

deeply bisinuate at the base; densely punctate. Hlytra convex, subtriangular, broadly produced at the

apex, strongly sinuate at the base, slightly compressed at the sides below the oblique humeral ridge ;

seriate-punctate, the punctures subquadrate, the interstices densely, minutely punctulate, 2 and 4 each

with two oblong setigerous prominences, 6 and 8 also a little raised, and 10 with a laterally projecting

prominence below the base. Legs stout, the femora unarmed.

Subovate, black, the antenne ferruginous ; densely clothed with pale brownish scales, the elytra with a large

whitish or brownish-white patch covering the apical declivity, the elevations each with a cluster of

short, coarse, erect sete, the prothorax with four fascicles of erect ochreous setee—two on the disc

and two at the apex, the legs setulose. Head densely punctate, depressed between the eyes; rostrum

short and very stout, closely punctate and faintly carinate. Prothorax a little broader than long, conical,

Braziu 12,

The thirteen specimens before me of this insect vary much in size (length 44-64,

breadth 24-34 mm.). It is comparatively shorter and broader than P. setiferus ; the

elytral vestiture is usually darker and the sete shorter; the groove on the disc of the

prothorax is broader; and the first ventral segment (as noted by Capt. Casey) has

scattered coarse punctures intermixed with the finer ones. P. budlatus was described

from a single worn example.

are from Costa Rica. It is extremely like P. muriceus, but has the four dorsal

tubercles on the prothorax more approximate (the longitudinal median groove thus

being narrower), and the first ventral segment is very coarsely punctate. In fresh

examples the elytra are densely clothed with cinereous or brownish-white scales, with

some darker markings at the base. The punctuation of the first ventral segment

1s very coarse, and closer in some specimens than in others. A Costa Rican example

is figured.

4. Phyrdenus tincticollis, sp.n. (Tab. XXIV. figg. 30, 30a.)

Ovate, convex, black, the elytra more or less mottled with ferruginous, the antenne and tarsi of the same

colour; densely clothed with brownish-white or cinereous scales, which become more or less fulvous on

the head and prothorax, intermixed with a long, erect, abundant setosity, the elytra each with a small,

sharply-defined, fuscous or blackish spot near the suture towards the tip. Head and rostrum densely,

rugulosely punctate, the latter carinate towards the tip, the head deeply transversely impressed in front.

Prothorax small, transverse, abruptly narrowed and constricted anteriorly, the sides parallel behind ;

opaque, densely, finely punctate, binodose in front, apparently canaliculate down the middle (this

appearance being due to the arrangement of the scales). Elytra coarsely seriate-punctate, shining, the

interstices 3, 5, and 7 slightly raised. Beneath very densely, finely, confluently punctate, the punctuation

of the first ventral segment a little coarser than that of the following segments, the second shorter than

the third and fourth united. Femora unarmed.

raised alternate elytral interstices, the almost level disc of the prothorax (except at

the apex), the rather fine punctuation of the first ventral segment, and the two blackish

spots towards the apex of the elytra, sufficiently distinguish P. tincticollis. ‘The

species probably extends into South America.

METADUPUS.

Metadupus, Schéuherr, Gen. Cure. iv. p. 166 (1837) ; Lacordaire, Gen. Col. vii. p. 101.

This genus includes a single very variable species, peculiar, so far as at present

known, to Tropical America. Lacordaire placed Metadupus in the “'Tylodides” on

account of the narrow metathoracic episterna; but as the insect is winged, and has a

rather large scutellum and long tarsal claws, it is better placed in Division II. The

mesosternum is horseshoe-shaped : in many of the Mexican and Guatemalan specimens

it is so feebly excavate that the rostral canal might almost be described as open

behind, whereas in those from Nicaragua and Panama the excavation is deep and the

walls very prominent. The antenne are inserted near the tip of the rostrum in the

male; the second joint of the funiculus is longer than the first.

female.

510 RHYNCHOPHORA.

ARTHROCORYNUS.

Rostrum stout, rather short, flattened at the tip, a little widened at the base and apex, the scrobes deep and

descending to the lower limit of the eyes; eyes very large, finely facetted, widely separated; antenne

inserted at about the middle of the rostrum in both sexes, the funiculus 7-jointed, 2 a little longer than 1,

the club ovate, acuminate, with deep transverse sutures; prothorax broader than long, narrowly and

arcuately produced at the apex, the base very deeply bisinuate, the median lobe truncate, the hind angles

broadly and obliquely truncate and received into the excavate base of the elytra, the ocular lobes well-

developed ; scutellum rounded, rather small; elytra not or very little wider than the prothorax, with

nine rows of punctures and also a short outer row at the base, the humeri sharply produced in front ;

prosternum with a very deep rostral canal; mesosternum raised, broad, extending forwards, arcuately

emarginate in front; metasternum rather short, the episterna moderately broad; ventral segments

3 and 4 each a little shorter than 2; legs rugosely punctate, comparatively short in the 9, longer in the

3, the anterior pair (except in poorly-developed specimens) greatly elongated in the latter sex; femora

feebly clavate and unidentate, the anterior pair in the ¢ very long, linear, slightly curved inwards,

and feebly dentate ; tibia carinate, unguiculate at the outer apical angle, the anterior pair in the ¢ very

long and sinuously bowed inwards ; tarsi with joint 3 strongly bilobed, the anterior pair of the g clothed

with long, projecting hairs, and sometimes with joints 1 and 2 asymmetrically formed, the claws simple ;

body oblong-ovate, robust, squamose.

Two species are referred to this genus, both of which have long been known under

MSS. names of Chevrolat or Jekel. They agree with Gasterocercus in the form of the

mesosternum, but can hardly be included in it, even in the widest sense, on account

of the trilobate base of the prothorax, the elongated anterior legs of the male, the

sublinear anterior femora in this sex, the less flattened rostrum, &c. The sculpture of

the rostrum is variable in the females.

1. Arthrocorynus brachialis, sp. n. (Tab. XXV. fige. 11,lla, ¢; 113, an-

terior tarsus, ¢; 12, anterior leg, 2.)

Gasterocercus brachialis, Jekel, in litt.’.

Gasterocercus mexicanus, Chevr. in litt.’.

Black, variegated with fulvous, cinereous or white, and blackish scales, the whitish scales condensed into three

patches at the base of the prothorax, and a broad, transverse, scutellar patch and a subapical fascia on the

elytra ; the vestiture of the under surface and legs sparser, the latter subannulate. Head densely,

rugosely punctate, flattened or depressed between the eyes, which are separated by the width of the

Tostrum; rostrum curved, rugosely punctate, except along the smooth raised median line, which

becomes cariniform at the base, very much smoother in some specimens of the 9. Prothorax constricted

and greatly narrowed in front, the sides subparallel at the base; densely punctate and also carinate.

Elytra subparallel towards the base, narrowing from before the middle, the scutellar region transversely

depressed ; seriate-punctate, the interstices conspicuously seriato-granulate, the alternate ones raised.

Beneath coarsely punctate. Anterior femora obsoletely dentate, the anterior tibie serrulate within, and

the anterior tarsi with joints 1 and 2 strongly dilated on the outer side at the apex, in the 3.

of the anterior legs of the male. The asymmetrically dilated basal joints of the

anterior tarsi in this sex, the transverse whitish patch at the base of the elytra, &c.,

distinguish the present species from the following one. In some of the females from

Panzos and San Isidro the rostrum is almost smooth.

2. Arthrocorynus dotatus, sp. n. (Tab. XXV. figg. 13, ¢; 134, anterior

tarsus, 3 .)

Gasterocercus dorsalis, Chevr. in litt.

Very like A. brachialis, but with the vestiture of the upper surface brown or fulvous, variegated with black,

the prothorax with a short streak in the middle at the base, and sometimes another at the apex, and the

elytra each with an irregular transverse more or less distinct patch at about the middle of the disc, white.

Elytra not transversely depressed in the scutellar region, with all the interstices convex and seriato-

granulate. Anterior legs of the ¢ very elongate, and their tibiew denticulate on the outer face, in well-

developed specimens, sometimes very little longer than in the @ and with the tibie unarmed; the tooth

on the anterior femora very small, and the two basal joints of the anterior tarsi normally formed, in

the 3.

Length 63-104, breadth 3-5 millim. (¢ 9.)

Hab. Mxxico, Orizaba (Sallé) ; Guaremata, San Isidro, Guatemala City (Champion) ;

Panama, Bugaba (Champion).

Ten specimens, seven of which are from Mexico. The variation in the development

of the anterior legs of the male is greater than in A. brachialis; examples of this sex,

however, are always distinguishable by the hairy anterior tarsi and the small tooth of

the anterior femora. The specific name dorsalis has already been used in at least two

of the allied genera.

MECISTOCORYNUS, gen. nov.

Rostrum rather slender, about as long as the head and prothorax, a little widened at the base ; eyes very

large, subapproximate ; antennz inserted at the middle of the rostrum in the ¢, and nearer the base in

the 9, the funiculus 7-jointed, 2 elongate in the ¢, 5-7 transverse, the club subcylindrical, very elongate,

pubescent, the sutures oblique, the two basal joints tubulate and extending far forwards on the lower

face; prothorax broader in the ¢ than in the ?, with feebly developed ocular lobes, the vibrisse short,

the base almost straight; scutellum small, transverse; elytra not (¢ ) or very little (2) wider than the

prothorax, with nine rows of punctures and also a short outer row at the base ; prosternum with a very

deep rostral canal, the latter reaching to about the middle of the intermediate coxe, the mesosternum

horseshoe-shaped ; metasternum rather long, the episterna broad ; ventral segments 3 and 4 each slightly

shorter than 2, the first suture curved; legs comparatively short in the Q, longer in the d, the

anterior pair greatly elongated and modified in this sex ; femora feebly clavate in the 9, sublinear in the

dg, unidentate (the anterior pair of the g excepted); tibie unguiculate at the outer apical angle, the

anterior pair of the ¢ very long, sinuous, denticulate and suleate within, and sharply mucronate at the

inner apical angle ; anterior tarsi of the ¢ (fig. 14 c) with joint 1 nearly twice as long as the others united,

and also dilated on the inner side near the base and at the apex, sulecate beneath, without projecting

hairs ; body oblong-ovate, squamose.

This genus includes a single species from Central America. It approaches Macro-

merus, Cylindrocorynus, and Celosternus in one or other of its characters. The male is

a very remarkable insect.

Found in numbers at Torola, on fallen timber, females predominating. The peculiar

structure of the front legs of the male is given under the definition of the genus.

MACROMEROPSIS, gen. nov.

Rostrum moderately long, curved, subcylindrical ; eyes very large, finely facetted, rather narrowly separated ;

antenne inserted behind the middle of the rostrum, joint 2 of the funiculus elongate, the club subcylin-

allied South-American form with the sides of the elytra still more hairy.

1, Macromeropsis binotatus, sp.n. (Tab. XXV. fige. 15,15 a, ¢; 150, an-

terior tarsus, ¢ .)

Subovate, robust, dull, black, the antenna obscure ferruginous ; mottled above with a dense clothing of fulvous

disc of the posterior portion of the prothorax, and also clustered into a large irregular patch around the

subquadrate white spot on the disc of each elytron beyond the middle, the scutellum and a small spot on

the flanks of the prothorax white or ochreous; the elytra moderately ciliate at the sides in the ¢; the

vestiture of the under surface sparse and pale, that of the legs closer, the scales on the latter sometimes in

great part fulvous (in one specimen carmine-red), the tibize annulate with fuscous near the base. Head

Thirteen specimens. The velvety-black markings on the upper surface vary in

extent, these more or less surrounding the white spot on each elytron, and the curved,

sinuous vitte on the prothorax are sometimes interrupted.

2. Macromeropsis quadrinotatus, sp. n. (Tab. XXV. figg. 16, 16a, ¢ ;

16 4, anterior tarsus, ¢ .)

Very like M. binotatus, but with a conspicuous spot on each of the shoulders of the elytra, as well as a

rounded spot on the disc beyond the middle, ochreous or fulvous, the prothorax with a dense similarly-

coloured patch in front of the anterior cox beneath, in addition to the small spot on the flanks; the

rostrum sharply carinate down the middle at the base, the outer caring interrupted or irregular ; the

CYLINDROCORYNUS.

Cylindrocorynus, Schénherr, Gen. Cure. iv. p. 231 (1837) ; Lacordaire, Gen. Col. vii. p. 123.

The two Tropical-American species included in this genus by Schonherr, one of

which extends northwards to Mexico, are very closely related to Celosternus compernis

and its allies, but differ from them in having the anterior tarsi of the males simply

dilated, without projecting hairs.

Lacordaire restricts this genus to C. compernis (Germ.) and its allies, one of which,

C. tardipes, Boh., is a common species within our limits. These insects have the

anterior legs of the male more or less elongated, and the anterior tarsi clothed with

long, projecting hairs in this sex; the rostrum rather slender; the canal reaching the

front of the metasternum ; the eyes very large; the antenne inserted at or behind the

middle of the rostrum, the club elongate or oblong; the ventral segments 2—4 equal

A common insect in Central America, and there representing the southern C. com-

pernis. In fully-developed examples the anterior femora have two small teeth exterior

to the large one, and the latter serrate on its outer edge, and the other femora sharply

bidentate; but in our long series of upwards of 100 specimens there are many (both

g and 2) with the anterior and intermediate pairs simply bidentate, and the posterior

pair unidentate. The upper surface is often set with intermixed erect scales, those on

the elytra being clustered along each side of the cost. The male, which appears to

be very much rarer than the female, has the anterior tarsi clothed on the inner side

with long projecting fulvous hairs. The length varies from 54-9 millimetres.

Six females from Chiriqui have a shorter rostrum and more elongate elytra, and

they may belong to a different species.

2. Celosternus acutidens, sp.n. (Tab. XXV. figg. 19,19 a, ¢; 198, anterior

Oblong-ovate, black, the antenne ferruginous; variegated above with fulvous, yellowish-white or white, and

blackish scales (the whitish scales sometimes condensed into two faint vitte on the prothorax), with a

few erect scales intermixed, the vestiture of the under surface and legs paler, the femora annulate. Head

densely punctate, sometimes feebly, obliquely carinate on each side above the eyes, the latter very large

and narrowly separated ; rostrum curved, moderately long, rugosely punctate and carinate, with the apical

half or more very sparsely, finely punctate; antenne with the club about as long as joints 3-7 of the

funiculus united, joint 2 of the latter elongate. Prothorax slightly broader than long, much narrowed in

front ; densely punctate and obsoletely granulate, sharply carinate down the middle. Elytra much wider

than the prothorax, narrowing from a little below the base, the humeri rather prominent; seriate-punctate,

the alternate interstices sharply costate. Beneath coarsely punctate. Anterior femora strongly, and the

others more feebly, clavate, bidentate, the inner tooth on the anterior pair narrow, the outer tooth on

the intermediate and posterior pairs very small and often wanting. Anterior tibi slightly dilated on the

inner side at about the middle in both sexes. Anterior tarsi in the ¢ dilated and clothed on each side

with long, projecting, fulvous hairs.

Cryptorrhynchus affaber, Boh., and Hemilius glabrirostris (Boh.).

COPHES, gen. nov.

Rostrum curved, cylindrical, moderately stout, reaching to about the middle of the intermediate coxe in

the 2 ; eyes well-separated or distant (except in C. gibbus), usually rather prominent ; antenne with

the funiculus 7-jointed, 2 sometimes longer than 1, the club oblong or ovate; prothorax transverse,

bisinuate at the base, the ocular lobes feebly developed; scutellum rounded or oval; elytra of the

same width as, or wider than, the prothorax, with the tenth row of punctures abbreviated ; metasternum

moderately long, the episterna broad (except in C. cognatus) ; ventral segment 2 a little longer than 3;

anterior legs (in C. longiusculus, &c.) more or less elongated in the ¢; femora moderately or feebly clavate

(the anterior pair bidentate in C. longiusculus and C. quadricostatus), the posterior pair not extending

beyond the apex of the elytra; anterior tarsi of the ¢ clothed on each side with long, projecting hairs.

Ceelosternus longiusculus, Boh., is taken as the type of this genus, which also includes

various other Tropical-American forms. These insects differ from Macromerus in

having the legs shorter, the anterior pair less elongated in the male, the rostrum

shorter and stouter, reaching to about the middle of the intermediate coxe, and the

mesosternum horseshoe-shaped or triangular. ‘he relatively longer second ventral

segment and the shorter and less attenuate rostrum separate Cophes from Celosternus

as here understood. ‘The eyes are very large in C. gibbus. The anterior tarsi of the

male are dilated in C. longiusculus and narrow in C. bifurcatus. C. quadricostatus

and C. hieroglyphicus have the anterior legs of about the same length in the two sexes.

C. cognatus has narrow episterna and it may have to be removed from Cophes.

to be wanting in the female sex.

HEMILIUS.

Hemilius, Chevrolat, Bull. Soc. Ent. Fr. 1880, p. exi (part.).

H. glabrirostris is taken as the type of this genus. It has very strongly clavate,

sharply dentate, compressed femora (the anterior pair being particularly stout); the

tibie are neither toothed nor dilated externally at the apex; the tarsi are rather

slender; the rostrum is narrowed towards the tip ; the rostral canal reaches to about

the middle of the intermediate coxe; the ventral segments 2-4 are subequal in

length ; the head is convex and rather small. The sexual differences are scarcely

noticeable.

HEMILIOPSIS, gen. nov.

Femora stout, compressed, moderately clavate, feebly unidentate, the anterior pair unarmed in the g. Tibix

dentate externally at the apex, as well as strongly unguiculate at the outer apical angle and mucronate

at: the inner angle, the anterior pair bowed in the ¢. Mesosternum broad, horseshoe-shaped. Ventral

other characters as in Hemilius.

The type of this genus, Hemilius nudicollis, Chevr., is an interesting insect,

superficially resembling H. glabrirostris, Boh., but more nearly related to the Chilian

Empleurus dentipes, Boh. In the armature of the intermediate and posterior tibie it

approaches the Australian Psepholax latirostris, Pasc.

Found in numbers in Chiriqui, under the sappy bark of fallen trees. The sexes are

so different as to appear to be specifically distinct. The male is broader than the

female, and has the prothorax more transverse, and very much smoother on the disc ;

the anterior femora very stout and unarmed, the anterior tibie curved, with the apical

spurs approximate (fig. 294). The female has the disc of the prothorax coarsely,

sparsely punctate ; the anterior femora toothed, and the anterior tibie straighter, with

the apical spurs more distant (fig. 30); the rostrum smoother at the tip.

ZASCELIS.

Zascelis, Leconte, Proc. Am. Phil. Soc. xv. p. 256 (1876).

The species here referred to Zascelis are of elongate, oblong, or ovate shape, and

have the general facies of a large Baris. They agree in the following characters :—

Head convex, not carinate above the eyes, the latter almost or quite hidden in repose, depressed, coarsely

facetted, and laterally placed ; rostrum strongly retractile, curved, subcylindrical, rather slender ; antenne

inserted at or behind the middle of the rostrum, the funiculus 7-jointed, the club ovate or oblong-ovate ;

prothorax broader than long, deeply bisinuate at the base, with prominent ocular lobes ; scutellum flat-

tened or convex, the cavity large ; elytra wider than the prothorax, oblong, flattened on the disc, coarsely

seriate-punctate, the humeri rounded and not prominent; rostral canal nearly or quite reaching the

metasternum ; metasternum rather long, with broad episterna; ventral segment 2 longer than 3, 1 and 2

free, or connate at the middle (Z. glabrata and Z. rugosa), the first suture straight or curved ; legs short,

stout ; femora feebly clavate, unidentate, the intermediate and posterior pairs sulcate beneath; tibie

broad and compressed, all sharply carinate on their outer edge, the carina sometimes broken up into teeth

on the intermediate and posterior pairs; tarsal claws simple.

In addition to the three species placed in this genus by Leconte, Zascelis will include

Cryptorhynchus affaber, Boh., a common Central-American insect, and various new

forms described below. C. geminatus, Boh., from Brazil, is a near ally of Z irrorata,

Lec., but it has a shorter rostrum and subcontiguous eyes. Z. rugosa would be almost

equally well placed in Metriophilus, and Z. glabrata will probably have to be separated

eventually.

Pinos Altos in Chihuahua (Buchan-Hepburn) ; GuaTEMALA, near the city (Champion).

Five specimens, agreeing fairly well with Leconte’s description, so far as it goes.

Very like Cryptorhynchus geminatus, Boh., from Brazil, but narrower, and with the

eyes more widely separated, the rostrum longer, the prothoracic sculpture not so coarse,

the interstitial punctuation of the elytra much denser and finer, the rostrum more

elongate.

2. Zascelis carinipes, sp.n. (Tab. XXVI. figg. 4; 4 a, hind leg.)

Elongate-ovate, shining, black, the antenne obscure ferruginous, the outer tibial carina fulvous; somewhat sparsely

clothed with rather coarse, narrow, ochreous scales, which are here and there clustered into small fascicles

on the prothorax and elytra. Head rugosely punctate, without sulcus near the eyes, the latter depressed

and moderately distant ; rostrum rather slender, a little widened towards the base, curved, as long as the

head and prothorax, rugosely punctate and 5-carinate in its basal half, and sparsely punctate thence to

the tip, the apical half slightly smoother in the 2, the antennew inserted near the middle, joints 1 and 2

The large number of specimens (upwards of 100) referred to this species, the type

of which cannot now be found in the Stockholm Museum, agree in having a smooth,

deep, arcuate groove on each side of the front of the head, the rostrum thus appearing

to extend further upwards than usual. The sculpture of the prothorax and elytra is

very variable, as in Memactes, it being particularly coarse in the examples from British

Honduras, Vera Paz, and Panama. ‘The prothorax is parallel at the sides behind, and

usually has a more or less distinct median carina. ‘The elytra are flattened on the disc

anteriorly, and have rows of deep, subquadrate, approximate punctures, separated by

narrow, raised, subcostate interstices, which are in a few specimens punctate or rugose.

The vestiture is whitish or ochreous, sparse, sometimes condensed into three faint

lines on the prothorax, and fasciculate on the elytra. The tooth on the anterior

femora is rather long. The length varies from 64-84 millim., and the breadth from

22-34 millim.

In a single specimen ( 2 ) from the Volcan de Chiriqui the frontal sulci, instead of

extending upwards, are continued outwards along the upper edge of the eyes.

Oblong-ovate, shining, black, the antenne obscure ferruginous ; very sparsely clothed with narrow, piliform,

decumbent, ochreous scales, which on the elytra are here and there subfasciculate. Head coarsely punc-

tate, with a deep arcuate groove on each side between the eyes, the latter depressed ; rostrum strongly

curved, in repose reaching almost to the anterior limit of the metasternum, punctato-sulcate at the base,

and for the rest sparsely, very finely punctate. Prothorax much broader than long, rounded at the sides,

narrowed from near the base, the latter bisinuate; very coarsely, confluently punctate. Scutellum

on the anterior pair short. Tibise: narrowly and uninterruptedly carinate on their outer edge.

Length 83, breadth 44 millim.

Hab. Mexico, Acapulco (Hoge).

One specimen. Easily separable from Z. affaber by its ovate shape, the flatter,

punctate, elytral interstices, and closer vestiture, the scales on the prothorax fulvous

and those on the elytra whitish.

6. Zascelis rugosa, sp. n.

Oblong-ovate, shining, black, the antenne and the tips of the tarsi ferruginous ; somewhat thickly clothed

with coarse, intermixed, narrow, ochreous and white scales, the latter clustered into a small patch at the

middle of the base of the prothorax, another on the humeri in front, and several on the disc of the elytra,

many of the scales on the upper surface curled, decumbent, and setiform. Head closely, rugosely

punctate, except along the very narrow smooth space bordering the eyes, the latter depressed and widely

separated ; rostrum strongly curved, in repose nearly reaching the metasternum, rather slender, a little

fab. Muxico, Vera Cruz (Hoge); Panama, David (Champion).

Four specimens, three of which are from Chiriqui. This insect is recognizable by

its almost glabrous surface, the peculiar form of the intermediate and hind tibie, and

the connate first and second ventral segments of the abdomen. The fulvous cilia at

the apices of the four hinder tibie are visible from above. There are allied unnamed

forms from Brazil, from the Fry collection, in the British Museum.

Guatemala, San Juan in Vera Paz, El Reposo (Champion) ; Nicaracua, Chontales

(Belt) ; Costa Rica, Escazu (Biolley).

This fine species has exactly the facies of a large Barid. The scales are easily

abraded, the prothorax being almost bare. The curved tooth on the hind femora of

the male is formed by an apical prolongation of the inner carina beneath. The ocular

lobes of the prothorax are usually dentiform in this sex. The insect is found in

decaying trees. Seventeen specimens.

Tyloderma is represented by numerous species in North America, two of which

extend into our limits, and a few have been described from Tropical South America

and the Antilles. To the characters given by Casey, it may be added that the outer

row of punctures on the elytra is short. The genus is placed amongst the “ Tylodides ”

by Lacordaire, and amongst the ‘‘ Cryptorrhynchides vrais” by Faust, the metathoracic

episterna being very narrow. Tyloderma is one of the few Cryptorrhynchid genera

with a six-jointed funiculus.

We possess six specimens of this species, four of which are from the northern

frontier of Mexico. The male has the first ventral segment broadly depressed down

the middle, a character also to be found in the same sex of certain Memactes.

8. Tyloderma eneotinctum, sp.n. (Tab. XXVI. figg. 10, 10a.)

Oblong, narrow, convex, shining, rufo-piceous, with an eneous lustre, the elytra in one specimen with

indications of a broad reddish subapical fascia, the antenne ferruginous; very sparsely clothed

with yellowish-white pubescence, which is clustered into small scattered patches on the elytra.

Head and rostrum rather closely punctate, the head transversely depressed between the eyes, the

front foveate. Prothorax a little longer than broad, narrowing from the middle forwards, feebly

constricted before the apex; sparsely, very finely punctate. Elytra rather long, much wider than the

prothorax, subparallel in their basal fourth and rapidly narrowing thence to the tip, which is somewhat

pointed, the humeri rounded ; coarsely seriate-punctate, striate near the suture, the punctures becoming

obsolete and placed in deep striz towards the apex, the interstices almost smooth, convex at least on the

apical declivity. Metasternum and the base and tip of the abdomen coarsely, and the rest of the latter

very sparsely and minutely, punctate. Legs long and slender.

Length 43-43, breadth 14 millim.

? Baropsis, Leconte, Proc. Am. Phil. Soc. xv. p. 258 (1876).

To the characters given for Memactes it may be added that the short pygidium is

ventrally exposed in both sexes; the episterna are narrow and imperfectly separated

from the metasternum ; the elytra have the outer (tenth) row of punctures short; the

femora are dentate, but the tooth on the anterior pair is sometimes obsolete; the tibie

are short and compressed, strongly unguiculate at the outer apical angle, the posterior

pair at least mucronate at the inner angle, the anterior and intermediate pairs sinuate

within, the intermediate and posterior pairs with a row of short stiff cilia on the outer

edge at the apex.

Four species are now known from Mexico or Guatemala, and the genus probably

extends into the Southern United States.

Sent us in numbers by Hége. The sculpture of the upper surface (as in certain

species of Tyloderma) is very variable in this insect, the prothoracic punctures being

sometimes small and sometimes very large and foveiform (M. cribricollis, Deyr.), and

those of the elytral series varying much in size and number. The male has the first

two ventral segments broadly depressed down the middle, and the fifth slightly

hollowed at the apex, leaving the pygidium a little more exposed than in the female.

‘The pubescence is very short and inconspicuous, and easily abraded. The intermediate

and posterior femora only are distinctly dentate.

2. Mzmactes pilosus, sp. n.

Elongate-oval, somewhat depressed, shining, black, the legs piceous, the antenne and the tips of the tarsi

one specimen; rostrum foveolate and longitudinally wrinkled at the base, the apical half sparsely,

finely punctate. Prothorax a little broader than long, rounded at the sides, narrowed and feebly

constricted in front; very coarsely, closely punctate, except along a narrow, irregular, smooth space

down the middle. Scutellum minute. Elytra oblong-oval, at the base a little wider than the base of

Oblong-oval, shining, black, the antennz and the tips of the tarsi ferruginous; thickly clothed (when fresh)

with intermixed ochreous, brownish-white, and fuscous scales, the light-coloured scales clustered into

several irregular transverse patches on the basal half of the elytra and showing a tendency to form one

or two subapical fascie, the elytral interstices each with a row of semierect sete, the legs with piliform

scales. Head somewhat closely punctate, the eyes rather small, separated by about half the width of

the base of the rostrum; the latter very coarsely punctate and longitudinally wrinkled at the base, with

the apical half sparsely, finely punctate, smoother in the ?. Prothorax a little broader than long,

Eleven specimens. The dull surface (above and beneath), the short rostrum, and

the conspicuously maculate base and apex of the elytra, readily distinguish S. picti-

pennis. In fresh specimens the light-coloured scales on the elytra are rosy-red.

5. Staseas mexicanus, sp. n.

Oblong-ovate, rather shining, black, the antennez and the tips of the tarsi ferruginous; the prothorax sparsely

clothed with narrow, setiform, brownish or ochreous scales ; the elytra with small scattered patches of

rather coarse reddish or ochreous scales, which are sometimes condensed into a common, irregular, narrow,

transverse fascia at the commencement of the apical declivity, the rest of their surface more sparsely

clothed with brownish or fulvous scales, each interstice with a row of moderately long semierect sete ;

the under surface and legs sparsely clothed with narrow cinereous scales. Head rugulosely punctate,

the eyes somewhat widely separated ; rostrum stout, curved, shorter than the prothorax, thickly punctate,

rugose and subcarizate at the base, smoother in the 2, the antenne inserted at (Q ) or beyond ( ¢) the

Hab. Mexico (Koltze, Mus. Dresden), Oaxaca (Hoge); GuatemaLa, San Juan and

Panima in Vera Paz, Duefias, Capetillo (Champion); Panama, Volcan de Chiriqui

(Champion).

Numerous specimens. ‘This insect is very like the smaller examples of S. granulatus,

but it has the rostrum as short as in S. pictipennis and the eyes are somewhat widely

separated. The elytral sculpture is variable, the two individuals from Vera Paz being

very sparsely granulate.

CaZLOSTERNINUS, gen. nov.

Rostrum curved, rather short, a little widened at the base and apex, that of the @ transversely sulcate at the

pase above, the sculpture different in the two sexes; antennz inserted behind the middle of the rostrum,

the club oblong and compact; eyes transverse, pyriform, well-separated ; prothorax with moderately

prominent ocular lobes ; scutellum prominent, the cavity large; elytra elongate, narrow, very little wider

than the prothorax ; mesosternum very prominent, horseshoe-shaped; metasternum long, the episterna

moderately broad; ventral segments 2-4 equal in length, the sutures straight; legs short, stout, the

femora subclavate and unidentate ; tibie strongly unguiculate ; tarsi similarly formed in the two sexes,

534 RHYNCHOPHORA.

The insect upon which this genus is based is one of the numerous species included

under Celosternus by Schonherr, but which cannot be retained in it if C. compernis

(Germ.) is to be taken as the type. . |

C. longipennis is a narrow, elongate form, superficially resembling a patch of bird’s

excrement.

Of this species we have received thirteen specimens, two only of which are males.

The rostrum differs thus in the two sexes: in the male it is rugosely punctate and

feebly carinate to about the middle, and thickly punctate thence to the apex; in the

female it is very much smoother, and broadly bisulcate in front of the basal constric-

tion, the two grooves elongate-triangular in shape, densely squamose, and separated by

a smooth, outwardly widened, raised space. The head is canaliculate between the

eyes, and sometimes has a longitudinal carina on the vertex. The white scales on

the elytra are rounded and imbricate.

ATRICHIS.

Atrichis, Chevrolat, Ann. Soc. Ent. Fr. 1882, p. 55.

Chevrolat gives Celosternus delumbis (Germ.), Boh., as the type of this genus, and

includes various other species in it, one of which, A. albitarsus, Chevr., cannot,

however, be treated as congeneric. The name Africhis is here retained for a few

species nearly allied to C. delumbis, which are chiefly characterized by their strongly

transverse, rather prominent eyes (a peculiarity noticed by Lacordaire *, but not

mentioned by Chevrolat); the short, curved, stout rostrum, which is widened and

usually depressed at the base; the ovate or elongate, compact, antennal club; the

rather short, stout legs, with more or less clavate, uni- or bidentate femora; the

horseshoe-shaped mesosternum ; and the unequal length of the intermediate ventral

segments of the abdomen, 2 being a little longer than 8 or 4. The anterior tarsi are

similarly formed in the two sexes,

§ Antennal club ovate.

1. Atrichis occiduus, sp.n. (Tab. XXVIL figg. 19, 19 a, 3.)

Elongate-ovate, moderately convex, shining, black, the antenne obscure ferruginous ; thickly clothed with

Hab. Nicaragua, Chontales (Janson).

One rather worn specimen. ‘The vestiture in this species does not form definite

markings, but appears to be condensed into irregular patches separated by almost

bare spaces, but this may be due to rubbing.

4. Atrichis nubilans, sp.n. (Tab. XXVI. figg. 21, 21a, 2.)

Elongate-ovate, robust, shining, black, the antennze obscure ferruginous; thickly clothed with intermixed,

RHINOCHENUS.

Rhinochenus, Lucas, in Casteln. Voyage, vii. p. 171 (1859) ; Chevrolat, Ann. Soc. Ent. Belg. xiv.

p. 85 (1871).

Chevrolat, in his Monograph of this genus, enumerates eighteen species as belonging

to it (some of which are certainly nothing more than varieties), all from South America.

In R. stigma and its allies * the rostrum is very stout, short, rugulosely punctate in

the male, smoother in the female; the antennz are stout, and have a rather short,

annulate, blunt club; the eyes in repose are completely hidden by the ocular lobes

of the prothorax; the mesosternum is broad; the second ventral segment is a little

shorter than the third and fourth united, and separated from the first by a sinuous

suture; the legs are very stout and rather short, the femora feebly dentate. 2. stigma

is recorded as having been found in British Guianaf in the fruit of the so-calied

“locust-tree” (Hymenwa courbaril), which is widely distributed in Tropical America.

- This species extends northwards to Nicaragua.

DIPLOGRAMMUS.

Diplogrammus, Chevrolat, Bull. Soc. Ent. Fr. 1875, p. ex; 1877, p. 180.

Chevrolat referred six South-American species to this genus, which are mainly

recognizable by their rhomboidal or ovate form, short rostrum, snort subconical

prothorax, alternately costate elytral interstices, and peculiar coloration. ‘The Mexican

insect now added is very differently marked from all of them, and it has the eyes

rather coarsely facetted and the femora unarmed. ‘The ventral segments 2-4 are

equal in length.

at the base, a short oblique fascia on the outer part of the dise below this, a long curved stripe extending

from the humeri along the lower margin for some distance and then running upwards to about the middle

of the disc, and a curved oblique stripe near the apex, this latter extending narrowly forwards along the

outer part of the third interstice. Head densely punctate, with a smooth sulcus running along the inner

Blaborhinus, Chevrolat, Ann. Soc. Ent. Fr. 1882, p. 55.

Chevrolat referred two species to this genus, both from Brazil. The Nicaraguan insect

now added has the rostrum short and stout in both sexes—straight, canaliculate, and

acutely carinate in the male, curved and rugosely punctate in the female. The ventral

segments 2-4 are equal in length, the sutures deep. ‘The eyes are large, transverse,

subangular and narrowly separated above. The prothorax has feebly developed ocular

lobes. The scutellum is elongate. The elytra have rows of large, deep, oval punctures.

The four hinder femora are dentate, the anterior pair unarmed. The mesosternum is

horseshoe-shaped.

Under this genus are included Celosternus dorsalis, Ros., and C. exornatus, Boh.,

both well-known ‘Tropical-American forms, which extend northward to Mexico.

Lacordaire (Gen. Col. vil. p. 124, nota) has already called attention to the characters

of C. dorsalis. Ihave not noticed any external sexual marks of distinction in either

Of this insect we have received ten specimens, some of which are in very good

condition. The common, post-median, brownish, sutural patch on the elytra is

bordered externally with a blackish line, formed by the numerous dark sete clustered

at this place. The pair from Ventanas, and a male from Duenas (length 33 millim.),

are smaller and narrower than the rest, and they may belong to a different species.

COLLABISMODES, gen. nov.

Rostrum very short, scarcely so long as the prothorax, curved, and exceedingly stout in both sexes, the

antenne inserted at about the middle, the club stout, oblong-ovate; eyes large, transverse, coarsely

facetted, and rather narrowly separated ; femora linear, unarmed; tarsal claws connate at the base;

metathoracic episterna very narrow; the other characters as in Collubismus.

The single species referred to this genus is a common insect in Central America.

542 RHYNCHOPHORA.

Found in abundance at Duefias, the specimens varying in size and in the colour of the

scales, though the four clusters of sete on the prothorax and the darker sutural patch

of the elytra are always more or less conspicuous. ‘The latter is limited behind by a

common, more or less interrupted, V-shaped or arcuate blackish streak.

EUBULOMUS.

Eubulomus, Faust, Stett. ent. Zeit. 1896, pp. 55, 84.

The type of this genus, L. sticticus, Faust, from Venezuela, an insect occurring

within our limits, is recognizable by its subcontiguous, coarsely facetted eyes, the

rather short, curved rostrum, the obsoletely dentate, shallowly sulcate femora, the

multicostate elytra, the comparatively short second joint of the funiculus, &c.

The three species now added have the femora completely unarmed, the tibia sharply

carinate on their outer edge, and the eyes varying in size inter se. ‘They are all very

like the insects here placed at the head of the genus Lubulus.

1. Eubulomus sticticus. (Tab. XXVII. figg. 1, 1a, b.)

Eubulomus sticticus, Faust, Stett. ent. Zeit. 1896, p. 85°.

Subovate, shining, black, the antenne ferruginous; clothed with scattered, short, narrow, semiercct, setiform,

ochreous scales, the elytra also with intermixed, coarser, adpressed, similarly-coloured scales, which are

here and there fasciculate. Head rugosely punctate, the eyes contiguous ; rostrum strongly curved, very

little longer than the prothorax, widened, rugosely punctate, and subcarinate at the base, for the rest

sparsely, rather coarsely punctate, the antenne inserted at about the basal third, joint 2 of the funiculus

shorter than 1, the club ovate. Prothorax transverse, much narrowed in front, the sides parallel behind ;

coarsely, densely punctate, and sharply carinate from the base to the apex. Elytra much wider than the

striate, the narrowing from a little below the base, the humeri rounded and somewhat swollen ; punctate-

prothorax, interstices rugulose, 2-9 narrowly costate throughout, the ridge on 2, 3, 5, and 7 prominent.

Beneath very coarsely, closely punctate. Intermediate and posterior femora each with a minute tooth,

Tibiz almost straight.

Length 43-5, breadth 23-25 millim.

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).—Vunezvunta, San Esteban}.

Four specimens, differing from the type of LE. stictécus, Faust, in having the prothorax

a little less transverse and more sharply carinate. The femora were incorrectly

described by Faust as unarmed.

2. Kubulomus multicostatus, sp.n. (Tab. XXVII. figg. 2. 2a.)

Ovate, rather narrow, shining, black or piceous, the antenne ferruginous; clothed with widely scattered

ochreous scales, intermixed with numerous suberect, fine, pallid setee, the scales more or less fasciculate

on the elytra, the vestiture of the under surface sparse and fine, the legs sparsely setulose. Head

coarsely, not very closely punctate, the eyes large, coarsely facetted, and narrowly separated ; rostrum

strongly curved, thickened basally, reaching to the middle of the intermediate coxe, tricarinate and

coarsely lineato-punctate at the base, for the rest sparsely punctate, smooth along the middle, the antennae

inserted at about the basal fourth, joint 2 of the funiculus shorter than 1, the club ovate. Prothorax

transverse, much narrowed in front, rounded at the sides anteriorly ; coarsely, confluently punctate.

Elytra wider than the prothorax, gradually narrowing from a little below the base, flattened on the

dise anteriorly, the humeri rounded; with rows of subquadrate punctures placed in shallow striae,

the interstices equally and narrowly costate throughout, the suture also raised. Beneath coarsely,

closely punctate. Legs short, rather stout, coarsely punctate; femora unarmed ; tibie straight on their

inner, and sharply carinate on their outer edge, the posterior pair gradually widened in their basal two-

thirds and narrowed thence to the apex.

Length 4-5, breadth 14-23 millim.

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

Numerous specimens. Separable from the other allied forms with multicostate

elytra by the basally thickened rostrum (this being especially noticeable when the

insect is viewed in profile), the non-carinate prothorax, the fine vestiture of the under

surface, the unarmed femora, and the externally widened posterior tibiz.

3. Eubulomus reflexirostris, sp. n.

Ovate, narrow, shining, black or piceous, the antenne ferruginous; clothed with widely scattered ochreous

scales and short semierect pallid sete, the scales fasciculate on the elytra, the vestiture of the under

surface sparse and fine, the legs sparsely setulose. Head rugosely punctate, carinate and transversely

depressed in front, the eyes distant ; rostrum strongly curved, cylindrical, constricted at the base, reaching

about as far as the anterior margin of the front coxe, tricarinate and rugosely punctate, a little smoother

Hab. Guaremata, Cubilguitz in Vera Paz (Champion); Nicaragua, Chontales

(Janson); Panama, Bugaba, Volcan de Chiriqui (Champion).

Eight specimens, all but two from Chiriqui. Very like £. mu(ticostatus, but smaller,

the rostrum shorter, cylindrical, and tricarinate to near the apex in the male, the eyes

distant, the head rugosely punctate and more or less distinctly carinate.

4. Kubulomus squamiventris, sp. n.

Very like E. reflexirostris, but with both the prothorax and elytra a little more rapidly narrowed from the

base, the setae numerous on the upper surface, the ventral segments clothed with coarse scales ; the head

coarsely, closely punctate, not carinate; the rostrum tricarinate and rugosely punctate, widened towards

the base, and constricted in front of the narrowly separated eyes; the prothorax coarsely, confluently

punctate, not carinate ; the tibie almost straight, carinate externally.

Length 32-4, breadth 2 millim.

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

Three specimens. ‘he coarsely squamose abdomen, the more sparsely punctate

head, the non-contiguous eyes, the shorter rostrum, and the somewhat rhomboidal

general form, distinguish this species from 4. mnulticostatus.

EUBULUS.

Eubulus, Kirsch, Berl. ent. Zeitschr. 1869, p. 200.

Cryptorhynchus (Division A-a*), Leconte, Proc. Am. Phil. Soc. xv. p. 250.

The characters given by Kirsch would have to be emended to include the numerous

species here described under Eubulus. Some of those placed at the head of the genus

migat be almost equally well referred to Zascelis, and the small forms placed towards

the end have a very different facies. ‘The five enumerated by Kirsch, of which Crypto-

rhynchus orthomasticus, Germ., may be taken as the type, are of large size, and they

all occur within our limits.

The Central-American forms agree in the following characters :—

Elytra narrowed from, or from a little below, the base, with the alternate interstices, and sometimes the others

also, costate, the humeri either prominent or forming an almost continuous outline with the sides of the

prothorax. Rostrum reaching as far as or beyond the middle of the intermediate coxe, in the typical

forms slightly impinging on the anterior margin of the metasternum. Legs similar in the two sexes ;

femora often bidentate or at least with indications of a second tooth, in some species unidentate ; tibie

rounded or angulate at the base externally, more or less distinctly carinate on the outer edge, the carina

(when prominent) straight and uninterrupted. Mesosternal excavation oblong or horseshoe-shaped.

Ventral segments 2-4 subequal in length, or 2 a little shorter than 3, the first suture arched or straight.

Antenne with an ovate or oblong club; funiculus with joint 2 elongated in the typicai forms.

The various species may be grouped thus :—

A. Tibiz rounded at the base externally; head usually carinate above the eyes.

a. Elytra with all the interstices costate; femora bi- or unidentate ; joint 2 of

the funiculus not longer than 1; body oblong-ovate or ovate, Baridiiform. Species 1-4.

Sect. A.

1. Eubulus punctifrons, sp.n. (Lab. XXVII. figg. 3, 3a, 4, ¢ .)

Ovate, somewhat flattened above, shining, black, the antenne and the tip of the rostrum more or less

ferruginous ; clothed with scattered rather coarse ochreous scales, which are clustered into fascicles on

the elytra, intermixed with very short, fine, erect sete. Head coarsely, closely punctate, the carina

between the eyes limited above by a small triangular fovea and on each side by a groove running along

the inner margin of the eyes; rostrum about as long as the head and prothorax, rather slender, curved,

tricarinate, punctate, and laterally sulcate at the base, and sparsely finely punctate thence to the tip,

the apical half almost smooth in the 2, the antennx inserted at (¢) or a little behind (¢ ) the middle,

joints 1 and 2 of the funiculus equal in length, the club ovate, acuminate. Prothorax much broader

than long, rapidly narrowing from the base ; coarsely, rugosely punctate, the smooth narrow interspaces

becoming longitudinally confluent anteriorly, the disc with a smooth, prominent, median carina. Scutellum

oblong, smooth. Elytra narrowing from the base, with rows of coarse, subquadrate punctures, the inter-

stices narrow, smooth, and costate throughout. Beneath very coarsely punctate. Femora sharply

unidentate. Tibi uninterruptedly carinate on their outer edge.

Length 53-64, breadth 3-34 millim. (d¢ 2.)

Hab. Muxico (Dupont, in Mus. Brit.), Playa Vicente (Sallé), Tapachula (Hoge),

MALA, Cahabon, San Gerénimo, El Reposo, San Isidro, Paraiso (Champion); PANaMa,

Bugaba, Volcan de Chiriqui, David (Champion).

Numerous examples. This insect may be recognized from most of its allies by the

groove along the inner margin of the eyes, and by the median carina of the rostrum

extending upwards between them, and then obliquely branching off for a short distance

on each side above. LE. punctifrons might be almost equally well included under

Zascelis. Cryptorhynchus serius, Ros., from Brazil, is probably an allied form.

2. Kubulus squamipennis, sp.n. (Tab. XXVII. figg. 4, 44, 6.)

Ovate, shining, black, the antenne and the outer tibial carina ferruginous; the pronotum sparsely, and the rest

of the surface somewhat thickly, clothed with rather coarse, subsetiform, ochreous scales, those on the flanks

of the prothorax larger and subtriangular. Head rugosely punctate, sometimes with an obtuse, subtri-

angular ridge between the eyes above, the latter subcontiguous, separated by the upward prolongation of

the median carina of the rostrum; rostrum curved, nearly reaching the metasternum, widened, rugosely

punctate, and carinate at the base, for the rest very sparsely minutely punctate in the ¢ and almost

smooth in the 9, the antenne inserted far behind the middle, joints 1-4 of the funiculus gradually

decreasing in length, 5-7 shorter than 4, the club ovate. Prothorax transverse, much narrowed and

feebly constricted in front and bisinuate at the base, the sides parallel behind; coarsely, confluently

punctate, and also carinate to near the base. Sceutellum oblong, smooth. LElytra considerably wider

than the prothorax, narrowing from a little below the rounded humeri; seriate-punctate, the interstices

rugulose, each of them narrowly costate (the ridge on 3, 5, and 7 rather prominent), and the suture also

raised. Ventral segments sparsely, coarsely punctate. Legs rather stout; femora sharply dentate, the

anterior pair with a small denticle placed at some distance exterior to the larger tooth; tibis carinate

on their outer edge.

Length 44-6, breadth 22-3 millim. (¢ 2.)

Hab, Payama, Bugaba (Champion).

Eleven specimens. Not unlike Eubwlomus sticticus, but larger and more ovate, the

rostrum much longer, the prothorax more coarsely punctate, with the narrow raised

interspaces becoming longitudinally confluent anteriorly, the legs stouter, the anterior

femora bidentate, the tibie broader and carinate along their outer edge. The almost

contiguous eyes distinguish E. sguamipennis from E. punctifrons, &c. The elytral

vestiture is rather close, coarse, and uniformly distributed.

3. Eubulus costatus, sp. n.

Oblong subovate, shining, black, the antenne fusco-ferruginous ; very sparsely clothed with small brownish

scales and also set with short, fine, suberect, scattered sete, the ventral segments 2—4 with a few very coarse

brown scales. Head very coarsely punctate, obliquely carinate above the eyes, the two carine connected

in front by a transverse ridge, the eyes distant; rostrum arcuate, not quite reaching the metasternum,

rugosely punctate and tricarinate in its basal half, the median carina extending upwards between the eyes,

the apical half almost smooth, the antenne inserted at about the middle, joints 1 and 2 of the funiculus

equal in length, the club ovate. Prothorax slightly broader than long, narrowed and feebly constricted

in front, the sides subparallel from about the middle to the base; very coarsely, confluently punctate, and

also carinate to the apex. Seutellum very small and convex, not filling the cavity. lytra wider than

the prothorax, narrowing from about the basal fourth, broadly produced at the apex, the humeri rounded ;

seriate-punctate, striate near the suture, the interstices obsoletely granulate and sharply costate, the

suture also a little raised. Ventral segment 1 very coarsely and closely, and the others sparsely and finely,

punctate, 2 smooth across the middle. Legs moderately long, the femora each with a triangular tooth.

Length 6, breadth 27 millim. (9 2)

Hab. Panama, Bugaba (Champion).

One specimen, partly abraded above. The longer legs, the less transverse prothorax,

and the broadly produced elytra distinguish E. costatus from E. punctifrons and

E. squamipennis. The ventral segments are very unequally punctured, and 2-4 bear

some coarse scales.

4. Bubulus truncatus, sp.n. (Tab. XXVII. figg. 5, 5 a.)

Oblong-ovate, shining, nigro-piceous or black, the antenne ferruginous; sparsely clothed with rather fine,

semierect, setiform, ochreous scales, the elytra with intermixed, coarser, adpressed, similarly-coloured

scales, which are here and there fasciculate. Head rugosely punctate, transversely carinate above the

eyes, the latter widely separated and coarsely facetted ; rostrum curved, nearly reaching the metasternum,

rugosely punctate and more or less distinctly carinate to about the middle and thickly punctate thence to

the apex, the apical half smocther in the 9, the antennee inserted about midway, joint 2 of the funiculus

a little shorter than 1, the club ovate, acuminate. Prothorax a little broader than long, abruptly

narrowed in front, the sides almost parallel to about the middle, the base strongly bisinuate ; coarsely,

confluently punctate, carinate from the base to the apex. Scutellum rounded, smooth. Elytra wider

than the prothorax, moderately long, rapidly narrowing from a little below the base, somewhat broadly

produced and subtruncate at the apex; punctate-striate, the interstices narrowly and equally costate

throughout. Beneath coarsely, closely punctate. Legs rather short; femora unidentate; tibie

feebly carinate.

Length 5-51, breadth 22 millim. (d @.)

Hab. Panama, Bugaba (Champion).

Four specimens. Separable from £. costatus, which also has a comparatively long,

very coarsely punctate, carinate prothorax, by the more widely separated eyes, the

truncate apex of the elytra, and the shorter legs.

5. Eubulus reticulatus, sp.n. (Tab. XXVII. figg. 6, 6a, b, 3.)

Ovate, shining, black, the antennz obscure ferruginous; variegated above with a somewhat dense clothing of

intermixed fulvous, black, and grey scales, the black scales forming a reticulate pattern on the prothorax

and elytra, the prothorax with the flanks and an oval or subcordate spot on the middle of the disc at the

base, and the elytra with a short streak on the fourth interstice towards the apex, ochreous or white ;

the upper surface also set with scattered, coarse, setiform scales, which are clustered into an interrupted

series on each of the four dorsal cost of the elytra; the vestiture of the under surface fulvous, that of

the legs variegate. Head rugulosely punctate, the exposed portion broadly flattened or depressed, in

some specimens obliquely carinate above each of the eyes and with a short carina on the vertex, the eyes

very large and narrowly separated; rostrum slender, curved, reaching the anterior edge of the meta-

sternum, widened, rugulosely punctate, and carinate at the base, and smooth thence to the tip, the

antenne inserted near the base, joints 1 and 2 of the funiculus subequal in length, the club elongate-

ovate, nearly as long as the preceding five joints united. Prothorax short, rounded at the sides anteriorly,

feebly constricted and greatly narrowed in front, bisinuate at the base; densely punctate and carinate.

Scutellum oval. Elytra moderately convex, slightly wider than the prothorax, narrowing from a little

below the base; seriate-punctate, the interstices punctulate, 3, 5, 7, and 9 sharply undulato-costate.

Beneath closely punctate. Legs rather stout; femora clavate, each with a very sharp triangular tooth

and a small tooth exterior to it.

Length 41~7, breadth 2,4,-34 millim. (d 9.)

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

Found in abundance in Bugaba. This insect is nearly related to the South-American

Colosternus aspis (Fabr.); but that species, according to Boheman, has the elytra

strongly tuberculate towards the base and wants the ochreous spot at the base of the

prothorax. If I have rightly identified the sexes, they have the rostrum and anterior

tarsi similarly formed.

The present species is very like Celosternus tardipes.

6. Kubulus hospes, sp. n.

Subovate, black, the antennw and the tips of the tarsi ferruginous; the prothorax with a tew svattered

whitish and fulvous scales above, the vestiture of the flanks coarse and close, whitish and fulvous

intermixed; the head with a sinuous, transverse, rusty-red line on the vertex; the elytra mottled with

rather coarse, blackish, rufo-fulvous, and whitish scales; the legs and under surface with fulvous and

ochreous scales, the latter condensed into an annulus on each of the femora; the upper surface also set

with very short, suberect, light and dark sete. Head rugulosely punctate, the eyes large and well-

separated; rostrum strongly curved, reaching the front of the metasternum, rugulosely punctured at the

base, and for the rest very finely punctate, the antenne inserted at the middle, joint 2 of the funiculus

slightly shorter than 1, the club ovate. Prothorax strongly transverse, rounded at the sides, abruptly

narrowed and feebly constricted in front; densely punctate and also carinate. Elytra rather short,

much wider than the prothorax, rapidly narrowing from about the basal third, the humeri obliquely

truncated in front ; shining, punctate-striate, the interstices rugulose, 3, 5, 7, and 9 very sharply costate.

Beneath coarsely, closely punctate. Legs rather short, rugosely punctate ; femora sharply unidentate.

Length 43, breadth 2} millim. ( ?)

Hab. Mexico, Jalapa (Hoge).

One specimen. This insect agrees with E. reticulatus in having the prothorax a

little narrowed behind and the alternate elytral interstices very sharply costate; but it

is much smaller, and has the antennal club ovate, the elytral cost uninterrupted, the

femora unidentate, &c. The reddish scales on the elytra are clustered into small

fascicles.

We have received fourteen specimens of this insect from within our limits, and I

have seen others from Cayenne, including one lent by the Stockholm Museum. It is

a species of rather large size and of oblong-rhomboidal form; the vestiture of the

dorsal surface is dark brown, the elytra mottled with whitish, and the prothorax

with a large ochreous spot on the disc behind, the sides of both prothorax and elytra

being clothed with paler brown or ochreous scales. The head is flattened, rugose, and

carinate above the eyes, which are large and not very widely separated; the rostrum is _

rugosely punctate and carinate, with the apical half more finely punctate in the female ;

the prothorax is sharply carinate down the middle and irregularly bicarinate towards

the sides; the alternate elytral interstices are sharply carinate, the ridge on the third

sinuous, that on the fifth interrupted ; the femora are bidentate. The fifth ventral

segment of the male is deeply foveate in the middle, the fovea limited posteriorly by a

semicircular elevation,

the prothorax, transversely convex, subtriangular, the humeri rounded and swollen; punctate-striate, the

interstices rugulose, 3,5, 7, and 9 very sharply costate. Beneath densely punctate. Mesosternal walls

vertical and dentiform in front. Legs moderately elongate; femora bidentate, the two teeth somewhat

widely separated, especially on the anterior pair.

Length 4—44, breadth 23 millim. (d 9.)

Hab. Panama, Bugaba (Champion).

One pair, somewhat worn. ‘This insect agrees with £. curvifasciatus in having a

bisinuate white frontal patch, but differs from that species in the shape of the

prothorax, the maculation of the elytra, and the longer legs. The flanks of the

prothorax are not clothed with white scales as in £. brevis and other allied forms. The

second joint of the funiculus is much elongated in the female.

Hab. Mexico2, Vera Cruz (Chevrolat '), Orizaba (Sallé); Guatemata, El Tumbador

and El Reposo, Pacific slope (Champion) ; Nicaragua, Chontales (Richardson).

Seven specimens, agreeing with the type communicated by Dr. Sjéstedt. Recog-

nizable by its rhomboidal form, the faint oblique whitish streak on each elytron, the

narrow, cylindrical, curved rostrum, the long legs, the elongate basal joint of the

posterior tarsi (this being more elongate than in the following species), and the almost

smooth second ventral segment, the sides only of the latter being punctured. The

first three joints of the funiculus are elongate. The short second ventral segment is

narrowly produced on each side behind, and there nearly reaches the apex of the

third, much as in EL. triangularvs.

25. Eubulus ineequalis, sp. n.

Cryptorhynchus inequalis, Chevr. in litt.

Rhomboidal, black, the antenne ferruginous ; somewhat thickly clothed with rather coarse, intermixed fulvous

each elytron and a faint annulus on the femora. Head rugosely punctate, sulcate on each side between

the eyes, which are very large and somewhat narrowly separated; rostrum rather slender, curved,

reaching the front of the metasternum, closely punctate and carinate at the base and minutely punctate

thence to the tip, the antenne inserted at the middle, joints 1 and 2 of the funiculus subequal in length,

the club ovate. Prothorax strongly transverse, subconical, the sides very feebly rounded and forming an

almost continuous outline with those of the elytra; densely, confluently, moderately coarsely punctate

and also carinate. Scutellum oblong, smooth. Elytra subtriangular, produced at the apex, the humeri

rounded; punctate-striate, the interstices rugulose, 3,5, 7, and 9 sharply costate. Ventral segments

coarsely punctate ; 2 with a single transverse row of punctures before the middle, smooth behind. Legs

moderately long; femora unidentate, and also armed with a small denticle exteriorly ; posterior tarsi

with the basal joint as long as 2-4 united.

Length 53-74, breadth 24-33 millim. (.)

Hab. Mexico, Matamoros Izucar, Puebla (Sallé) ; Nrcaracua, Chontales (Janson).

Four specimens, all but one from Mexico. Very like #. biangularis, but with the

coarse punctures before the middle. A single example of each species has been

received from Chontales.

96. Eubulus trigonalis, sp.n. (Tab. XXVII. figg. 25,.254, 2.)

Oblong-rhomboidal, nigro-piceous or black, the antennex ferruginous ; mottled above and beneath with a rather

dense clothing of intermixed fulvous (or ochreous) and whitish scales, which in fresh specimens are

clustered into a spot on the median lobe of the prothorax and an interrupted oblique streak on each side

of its disc, Head rugosely punctate, sulcate on each side between the eyes, which are separated by a

little less than the width of the rostrum ; rostrum rugosely punctate and carinate to near the middle and

coarsely punctate, 2 with two transverse rows of punctures in front; 1 depressed and pilose in the middle

in the g¢. Legs moderately long; femora unidentate, and also armed with a more or less distinct denticle

exteriorly ; posterior tibiz slightly hollowed at the apex within in the ¢ ; posterior tarsi with the

basal joint barely as long as 2-4 united.

second ventral segment with two incomplete rows of coarse punctures. The males

differ from those of the allied forms in the peculiarities noted above.

four joints united. Prothorax transverse, much narrowed and feebly constricted in front; densely,

rugosely punctate and also sharply carinate, the interspaces eranulate. Scutellum oblong, rather small,

with a smooth tubercle in front. Elytra much wider than the prothorax, subtriangular, considerably

produced at the apex; punctate-striate, the interstices sparsely granulate, 3, 5, 7, and 9 very sharply,

and 6 (except at the base) and 8 more feebly, carinate. Beneath coarsely, closely punctate. Meso-

sternal walls obtusely dentate in front. Legs elongate, the femora linear, unidentate.

Length 63, breadth 33 millim. (9 *)

Hab. Panama, Bugaba (Champion).

One specimen. This insect is nearly related to £. diaspis, from which it differs in

its coarser vestiture, the longer antennal club, the well-marked frontal depression, the

(Conradt) ; Nicaragua, Chontales (Belt, Janson).

A species inhabiting both the Atlantic and Pacific slopes of Central America, and

found by myself in abundance on the western slope of Guatemala. I have seen the

types of Rosenschoeld’s species and am unable to separate them: C. aspericollis is a

larger, more uniformly coloured form, and has the prothorax somewhat rounded at the

sides; C. cinctellus (fig. 32) has the prothorax and elytra much mottled with cinereous.

The prothorax is asperate and setose, and the sharp median carina extends forwards on

to the head and rostrum. ‘The “\-shaped carina on the head is sharply defined. The

second joint of the funiculus is longer than the first or third. The fifth ventral segment

of the male is simply squamose, not closely pilose as in EF. orthomasticus. The penis

of the male (fig. 33) is broad and slightly attenuate at the tip. The seventh dorsal

segment of the female (fig. 52 a) is broad and armed at the apex with four stout, blunt

teeth of equal length.

39. Kubulus pilipectus, sp. n. (Tab. XXVIII. figg. 1, la, ¢; 18, penis-

sheath.)

Subrhomboidal, black, the antennz fusco-ferruginous ; the prothorax densely clothed with coarse, adpressed,

fulvous scales, the vestiture of the rest of the upper surface sparser and finer, reddish-brown, with a few

intermixed black and whitish scales, the latter clustered into small scattered fascicles on the elytra, the

prothorax and elytra also set with scattered, very short, suberect, setiform scales; the legs and under

surface with intermixed whitish and fulvous scales. Head flattened in front, asperato-punctate,

the oblique carine above the eyes meeting at an obtuse angle in the middle, the vertex sometimes

carinate; rostrum strongly curved, rugosely punctate and sharply carinate in its basal two-fifths, and

sparsely, finely punctate thence to the tip, smoother in the 9, the antenne inserted behind the middle,

joint 2 of the funiculus elongate. Prothorax strongly transverse, constricted in front, the sides rapidly,

arcuately converging from the base; densely punctate, feebly asperate, and sharply carinate. Elytra

subcordate, seriate-punctate, the interstices 3,5, 7, and 9 very sharply costate, the ridge on 3 curved

down the middle of the first and fifth ventral segments, densely clothed with fulvous piliform scales in

the. Legs elongate; femora bidentate; tibie long and of almost equal width to the apex. Penis-sheath

broad, pointed at the tip.

Length 8,,-94, breadth 42-5}, millim. (d 2.)

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

Many specimens. The uniformly-coloured scales on the prothorax, the small

scattered fascicles of whitish scales on the elytra, the relatively long legs, with the

tibie of equal width to the apex, and the ¢ characters, distinguish this species. In

E. orthomasticus the fifth ventral segment only is pilose in the male; the prothorax is

more asperate and the vestiture more variegate; and the legs are shorter, the tibize

narrowed towards the apex.

40. Eubulus alticarinatus, sp.n. (Tab. XXVIII. fig. 2, penis, ¢.)

Extremely like E. pilipectus, but differing as follows :—The rostrum slightly shorter in both sexes; the second

joint of the funiculus less elongate, a little longer than the third; the prothorax more distinctly asperate,

the median carina becoming more prominent anteriorly ; the legs shorter, the tibia narrowed towards the

apex; the metasternum and ventral segments 1 and 5 not pilose in the g; the penis-sheath broad,

rounded at the tip.

Length 62-93, breadth 33-5 millim. (¢ @.)

Hab. Costa Rica, Pozo Azul (Underwood); Panama, Bugaba, Volcan de Chiriqui

(Champion).

A common insect in the forest-region of Chiriqui. It is so like EL. pilzpectus that

unless the males of each are compared the two species would certainly be confused.

The anteriorly raised prothoracic carina and the shorter, less parallel-sided tibia,

however, sufficiently distinguish H. alticarinatus. The uniformly coloured vestiture

of the prothorax, the less variegate elytra, &c. separate it from LH. aspericollis.

41. Eubulus camelus, sp. n. (Tab. XXVIII. figg. 3, 3a, ¢.)

Subrhomboidal, black, the antennz ferruginous ; the head and prothorax thickly clothed with fulvous scales,

the vestiture of the rest of the upper surface sparser, reddish-brown, the elytra with a few scattered,

suberect, setiform, whitish and blackish scales, the under surface and legs with intermixed reddish-brown

and white scales. Head flattened in front, asperato-punctate, the oblique carine above the eyes not

meeting at the middle; rostrum strongly curved, moderately long, rugosely punctate and carinate at the

base, sparsely, finely punctate in its outer half, the antenne inserted behind the middle, joint 2 of

Two specimens, both from the “tierra caliente ” of the Pacific slope. The coarsely

setose, broad, abruptly constricted, uneven prothorax, the mottled vestiture of the

One specimen. Extremely like Celosternus tardipes, but a little less elongate in

shape, the antennal club rotundate-ovate, the femora less clavate, the upper surface

without intermixed whitish scales. The subcontiguous eyes, the finer sculpture of

the prothorax, and the less mottled vestiture separate 7. deceptor from LE. irrubescens.

- Five specimens, one from each locality. The transverse, heart-shaped, fulvous patch

at the base of the elytra (which is surrounded by a dark annulus, and duplicated, as it

were, on the prothorax) sufficiently distinguishes this small species. The clusters of

coarse sete, as in the allied LH. discoideus, are easily abraded,

Length 32-4, breadth 2-2,1, millim. (¢ @.)

Hab. Panama, Volcan de Chiriqui (Champion).

Seven specimens. In this insect the vestiture of the upper surface is close and

blackish, and the elytra have each a short oblique ochreous streak on the disc, the

upper surface being also set with short, erect, black scales. The prothorax is subconical

in shape, and has a conspicuous cluster of erect black scales on the middle of the disc.

Its subrhomboidal form, smaller size, &c. separate #. melanotus from the N.-American

EF. parochus.

75. Hubulus moerens, sp. n.

Very like Z. melanotus, but with the blackish vestiture of the upper surface much intermixed with fulvous or

brown; the elytra in one specimen variegated with rufo-piceous, the oblique ochreous streak on the disc

wanting, the flanks of the prothorax and a spot beneath the shoulder whitish or ochreous, the erect scales

on the alternate interstices coarse, and those on the prothorax clustered into a small fascicle at the middle ;

the legs rather stout, the femora feebly unidentate, the tibiz subangulate at the base externally.

Length 32, breadth 1,9, millim. (d*)

Hab. Guaremata, Pantaleon (Champion); Panama, Caldera in Chiriqui (Champion).

Two specimens, the one from Panama in very clean condition. The mottled vestiture

of the entire upper surface and the more feebly dentate femora sufficiently distinguish

E. merens from £. seminiger.

Hab. Norra America! 245, Middle, Southern, and Western States to Texas °.—

Mexico, Jalapa (Hoge) ; Guaremana, Chacoj in Vera Paz (Champion).

Two specimens, agreeing perfectly with one from Massachusetts sent me by

Mr. Wickham. This is one of various extremely closely-allied forms, and mainly

distinguishable by the very short erect scales on the prothorax and elytra, each

elytron with an oblique whitish fascia before the middle, the tibie almost straight,

and angulate externally at the base, the femora feebly dentate.

77. Eubulus densus, sp. n. (Tab. XXVIII. figg. 25, 254, ¢ .)

Subrhomboidal, piceous, the antenne and the tips of the tarsi ferruginous; densely clothed with intermixed

whitish and flavo-cinereous scales, the prothorax with a few very short, semierect, scattered setz, the

legs subannulate. Head rugulosely punctate, the eyes large and well-separated ; rostrum curved, reaching

the metasternum, widened towards the base, rugulosely punctate and tricarinate, the apical half finely

punctate, smoother in the 2, the antenne inserted at a little behind the middle, joints 2-7 of the funiculus

slender, 2 much shorter than 1, the club stout, oblong-ovate. Prothorax short, subconical, feebly constricted

in front; densely punctate and arcuato-carinate. Elytra much wider than the prothorax, subtriangular,

parallel at the base ; punctate-striate, the interstices densely punctulate, 3, 5, 7, and 9 sharply costate.

Beneath opaque, closely punctate. Mesosternum horseshoe-shaped. Legs rather short; femora sub-

clavate, unidentate ; tibiee angulate at the base externally.

EUBULOPSIS, gen. nov.

Rostral canal impinging on the front of the metasternum in the ?, reaching to the middle of the intermediate

coxe in the d; eyes rounded above, large, rather narrowly separated; prothorax short, conical, with

feebly-developed ocular lobes; elytra triangular, much wider than the prothorax, with the alternate

interstices costate ; metasternum short, the episterna broad; ventral segments 2-4 subequal in length ;

femora without trace of tooth; tibis subangulate at the base externally, almost straight within.

The single species referred to this genus is very like many of the small forms here

placed in the second Section of Eubulus, but as the femora are completely unarmed it

is best separated.

1. Eubulopsis edentatus, sp. n. (Tab. XXVIII. figg. 26, 264, o; 27, meso-

sternum, ¢ .)

Rhomboidal, shining, rufo-piceous, the elytra usually with the apical half and a space at or below the base

blackish, the femora also sometimes infuscate at the middle, the antennez ferruginous ; sparsely clothed

with minute fulvous or brown scales, the flanks of the prothorax and the base of the rostrum whitish in

the g, the elytra with a more or less distinct, common, narrow, curved, whitish or fulvous fascia below the

base, extending forwards to the humeri, and sometimes some small scattered fulvous spots below it, their

surface also sparsely set with short, fine, suberect sete, the femora subannulate with whitish. Head

rugulosely punctate, the eyes rather narrowly separated ; rostrum moderately stout, curved, bare and

impinging on the metasternum in the 2 , squamose and a little shorter in the ¢, rugosely punctate, the

Hab. Mexico, San Juan Bautista in Tabasco (Hége: 2); Panama, Volcan de Chiriqui,

Boquete (Champion: 3 2).

Seven specimens, six of which are females. This species agrees with Hubulus curvt-

fasciatus in having a short, conical prothorax, a narrow curved fascia on the elytra, &c. ;

but the legs are shorter, the femora are unarmed, the rostrum is more slender and

scarcely widened towards the base, and the head is without an oblique carina above

the eyes. ‘The curved elytral fascia is less sharply defined in the Mexican examples

than in those from Chiriqui.

~ METOPOSOMA.

Metoposoma, Faust, Stett. ent. Zeit. 1896, pp. 53, 75.

This genus was based upon a single species, Cryptorhynchus funebris, Boh., from

Colombia and Venezuela, and another is now added from Guatemala. They are

closely related to various forms here referred to Metriophilus, differing from them in

having the elytra more sinuate along their lower margin, and the sides bare and

hollowed below the abbreviated carina on the ninth interstice. The eyes are com-

pletely covered by the prominent ocular lobes of the prothorax. The femora are

feebly dentate, the tooth on the anterior pair not longer than that on the others. The

vestiture of the elytra is dense. ‘The second ventral segment is much longer than

the third.

1. Metoposoma nigrofasciatum, sp.n. (Tab. XXVIII. figg. 28, 28 a.)

Oblong-ovate, black, the antennew and the tips of the tarsi obscure ferruginous, the prothorax dull, the rest of

the surface shining; the prothorax clothed with black scales, with three patches of white scales at the

base; the elytra densely clothed with white scales, with a common transverse patch at the base, one or

two spots below this, a broad, angulate, postmedian fascia, three small spots at the apex, and another

beneath the shoulder, black; the under surface and rostrum sparsely, and the legs densely, clothed with

white scales, the tibia annulate with black; the elytra also with a row of semierect scales down each

interstice. Head convex, rugulosely punctate, foveate between the depressed, laterally placed eyes ;

rostrum stout, curved, about as long as the prothorax, irregularly seriate-punctate, smooth along the

centre, the antennz inserted beyond the middle, stout, joint 2 of the funiculus shorter than 1, 3-7

moniliform, the club short ovate. Prothorax strongly transverse, rounded at the sides, narrowed in

front; coarsely, confluently punctate, and subcarinate. Scutellum convex. LHlytra about one-half wider

than the prothorax, subparallel in their basal third, depressed along the suture anteriorly; seriate-

punctate, the interstices closely punctulate, flat on the disc, 9 narrowly costate, except towards the base.

Beneath coarsely, sparsely punctate; fifth ventral segment densely punctate and squamose at the apex

in the ¢. Legs short and stout, the femora feebly dentate.

Five specimens. Less elongate than MJ. lugubre (Boh.), the prothorax more trans-

verse, the elytra with a complete, broad, angulate, black fascia, the alternate dorsal

interstices not raised. There are several other Central-American forms very like

M. nigrofasciatum, and with somewhat similar elytral vestiture, as Staseas pullatus, &c.

METRIOPHILUS.

Metriophilus, Faust, Stett. ent. Zeit. 1896, pp. 51, 62.

Faust included six species from Venezuela in this genus (the types of all of which I

have seen *), and numerous others are now added from Central America, including

Cryptorhynchus definitus, Ros. They agree in the following characters :-—

Rostrum strongly curved, sometimes gibbous at the base, reaching to about the middle of the intermediate

coxw ; eyes large, somewhat depressed, placed low down at the sides of the head, and covered in repose

by the prominent ocular lobes of the prothorax ; scutellum small; elytra wider than the prothorax, with

the tenth row of punctures abbreviated, and the interstices flat or convex, at most subcostate towards

the sides ; metathoracic episterna broad; legs usually short, similar in the two sexes; femora unidentate,

the tooth on the anterior pair longer than that on the intermediate and posterior pairs; tibie feebly

carinate ; tarsal claws simple; ventral-segment 2 considerably longer than 3, 1 and 2 connate at the

middle in M. definitus and M. nigrotermenatus.

Oblong-ovate, subopaque, nigro-piceous or black, the antenna obscure ferruginous; sparsely clothed with

small fulvous or greyish scales, which are somewhat fasciculate on the elytra and are often condensed

into a small patch on the median lobe of the prothorax, and also thickly set with long, suberect sete.

Head densely, rugulosely punctate, flattened above the widely separated eyes; rostrum strongly

Length 53-64, breadth 3-34 millim.

Hab. Panama, Volcan de Chiriqui (Champion).

Four specimens, probably including both sexes. Distinguishable by the numerous,

irregular, sinuous, interrupted lines of black sete on the elytra, the rather finely

punctured, fasciculate prothorax, and the very opaque surface, above and beneath.

Four specimens, all from the Pacific slope. Smaller and narrower than I, nigrescens ;

the prothorax angulate or dentate, and also subfasciculate, at the sides before the

middle, very abruptly narrowed in front, and sparsely, unequally punctate; the

scutellum small, &c. The black sete on the anterior portion of the elytra are

condensed on each side of the scutellum into an oblique line, which extends forwards

punctate, with four isolated fascicles of black sete placed transversely across the disc,

as well as two others at the apex, the sides not dentate ; the black lines on the elytra

not reaching the base. An allied form occurs in Brazil (Cryptorhynchus piligerus,

Jekel, in litt.).

other. The basally narrowed prothorax separates WV. nigrisetis from M. v-fulvwm and

other allied forms. The short, black, suberect, fascicularly-arranged scales give the

upper surface an uneven appearance.

16. Metriophilus v-fulvum, sp.n. (Lab. XXIX. figg. 5, 5 a.)

Subovate, rather broad, opaque, the antennx obscure ferruginous ; rather sparsely clothed with minute brown

scales intermixed with short, coarse, semierect, black sets, the latter clustered into six fascicles on the

prothorax (two at the apex and four across the middle) and various interrupted, sinuous, transverse

known to me with the intermediate tibie angulate towards the middle externally.

The elytra are rather sharply striate, the tenth stria extending to near the apex. The

eyes, as in Vetriophilus, are completely covered in repose by the prominent ocular

lobes of the prothorax.

posterior tibie are very distinctly angulate externally. Two from Bugaba are larger

and have the sides of the prothorax more dilated and the legs robust, with the femoral

tooth very sharp.

2. Piseus complanatus, sp.n. (Tab. XXIX. figg. 7; 74, intermediate leg. )

Oblong-ovate, narrow, depressed, piceous, the elytra sometimes mottled with rufous, the antenne and the

Length 23-8, breadth 13-13 millim. (¢ 9.)

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

Many specimens, varying in the extent of the angulation of the tibie. ‘This insect

is nearly related to P. varicus, but it is a little smaller and has the elytra more

depressed. The pallid scales on the prothorax are condensed at the sides and down

the middle. The shining elytral interstices (when the scales are removed) separate

P. complanatus from P. sulcatus. One of the specimens from Bugaba is more

elongate than the others, and has all the tibie broad and angulate.

3. Piszeus sulcatus, sp. n.

Subovate, rather narrow, nigro-piceous or black, the antenne and the tips of the tarsi ferruginous ; variegated

above with fulvous and blackish scales, and also thickly set with moderately long, erect, blunt, light and

dark sete ; the under surface and legs clothed with brownish or cinereous scales, the legs setose. Head,

rostrum, and antenne as in P. varicus. Elytra much wider than the prothorax, flattened on the disc

to this species; but it is broader, and has the legs stouter, the tibie less angulate

externally, and the elytral interstices rather shining.

TYRANNION, gen. nov.

Rostrum strongly curved, nearly or quite reaching the front of the metasternum ; antennz with the funiculus

7-jointed, the club ovate ; eyes coarsely facetted, large, partly exposed in repose ; prothorax transverse,

bisinuate at the base, with feebly developed ocular lobes; scutellum visible; elytra rather short, usually

much wider than the prothorax, narrowing from near the base, the alternate interstices not costate ;

mesosternum oblong or horseshoe-shaped; metathoracic episterna broad; ventral segment 2 longer than 3

(very slightly so in 7’. validus); legs short, similar in the two sexes, femora unidentate, tibiee rounded

externally at the base, tarsal claws simple; body ovate or subovate.

Type, 7. validus.

The numerous species from which the above characters are taken approach some of

the more aberrant forms here placed under Eudulus. They may be known by their

ovate form, the comparatively short, broad, non-costate elytra, the short prothorax, the

coarsely facetted, partly exposed eyes, the rather long, strongly arcuate rostrum,

the oblong or horseshoe-shaped mesosternum, &c. Tyrannion is no doubt well

represented in South America*. The Central-American forms, most of which appear

to be rare, may be grouped thus :—

10. Tyrannion disparilis, sp.n. (Tab. XXIX. fig. 16.)

Closely related to 7’. diffusus, but with the elytra relatively longer, the vestiture brown, mottled with

cinereous and black, the cinereous scales condensed into two interrupted, transverse, sinuous fascie

before the middle and the darker scales into various small scattered patches, the setiform scales less

regularly arranged ; the rostrum coarsely, rugosely punctate and carinate at the base, and somewhat

closely punctate thence to the tip, except along the middle ; the elytral interstices more distinctly

granulate, 3 raised and setose below the base.

Length 62, breadth 33 millim. (<7?)

Hab. Guaremata, Cerro Zunil, Pacific slope (Champion).

One specimen, differing as above described from T. diffusus. Compared with

T. suffusus, the present species is narrower and less depressed, the vestiture is not

so coarse and more mottled, the cinereous scales being condensed into two irregular

fasciee below the base, the legs are more slender, and the femora are less acutely

dentate. The rostrum has a more definite smooth space down the middle than in

T. pictilis, which also has the elytral vestiture differently coloured.

11. Tyrannion ochreopunctatus, sp.n. (Tab. XXIX. fig. 17.)

Ovate, moderately broad, black, the antennew obscure ferruginous ; rather sparsely clothed with small brown

or blackish scales, with scattered intermixed, coarser, ochreous scales, the latter clustered into six small

spots on the prothorax (four in a transverse series across the middle and two at the apex) and numerous

small spots on the elytra; the vestiture of the legs paler, that of the under surface sparse; the upper

surface also set with rather coarse, short, suberect, ochreous and blackish setiform scales. Head rugosely

punctate, the eyes distant: rostrum strongly curved, reaching to the middle of the intermediate coxa,

rugosely punctate and subcarinate at the base, and sparsely punctate thence to the tip, the antenne

inserted at or at a little beyond the middle. Prothorax transverse, rounded at the sides, much narrowed

and feebly constricted in front; densely, rather finely punctate. Elytra nearly one-half wider than the

prothorax, narrowing from about the basal third, flattened on the disc anteriorly, the humeri obtuse and

somewhat swollen; seriate-punctate, the interstices flat, punctulate, and sparsely, finely granulate.

Ventral segments shining, sparsely punctate. Mesosternum U-shaped. Femora feebly clavate, very

sharply unidentate. Intermediate tibie curved externally.

Length 675-63, breadth 3545-33 millim. (¢?)

Hab. Panama, Bugaba (Champion).

Three specimens. The fasciculate arrangement of the ochreous scales on both the

prothorax and elytra separate 7. ochreopunctatus from most of its allies. Various

Conotracheli (C. picticollis, &c.) are somewhat similarly marked.

12. Tyrannion punctipennis, sp.n. (Tab. XXIX. fig. 18.)

Very like 7’. ochreopunctatus, but differing as follows:—The vestiture coarser, the ochreous scales on the

prothorax not condensed into sharply-defined spots and those on the elytra here and there fasciculate,

the scutellum ochreous; the head obsoletely carinate down the middle, transversely depressed above the

eyes, which are larger and more approximate; the rostrum not so stout, a little longer, and less rugose

at the base; the prothorax relatively narrower, more coarsely punctate, carinate from the apex to near

the base; the scutellum larger; the rostral canal narrower; the ventral segments less shining, 2 more

closely punctate ; the legs a little longer ; the femoral tooth shorter and less acute; the intermediate

tibies less curved.

Length 632, breadth 32 millim. ( 2.)

Hab. Panama, Bugaba (Champion).

One specimen, differing too much from TZ. ochreopunctatus to be included under

that species, of which I at first thought it might be the sexual complement.

Six specimens; a seventh from Sinanja, Vera Paz, with rather darker scales and

shorter sete may also belong here. Smaller and narrower than 7. imbellis, the

antenne inserted beyond the middle of the rostrum in both sexes, the rostrum very

slightly widened towards the base, the vestiture ochreous and black intermixed, the

hidden terminal dorsal segment of the abdomen of the female tridentate (instead of

simply truncate) at the apex, the femoral tooth less acute.

Hab. Guatemata, Cerro Zunil (Champion).

Four specimens, one somewhat immature and with the base of the elytra reddish.

The short, broad, posteriorly widened form separates 7. curtipennis from the allied.

species. The elytral vestiture is somewhat variable in colour, the blackish scales being

Three specimens. In this insect the elytra have each a small, sharply-defined, white

spot on the outer part of the disc below the base (much as in the Venezuelan

Heterobothrus bipustulatus, Faust), and the prothorax is very short and much narrowed

anteriorly. Cryptorrhynchus verruca (Fabr.) is similarly marked.

21. Tyrannion breviculus, sp. n. (Tab. XXIX. fig. 21.)

Short ovate, shining, nigro-piceous or black, the head and the anterior portion of the prothorax usually in part

This genus is based upon Cryptorhynchus pilosellus, Boh., and I have not yet seen

any other insect that can be treated as congeneric. The type is a very small, oblong

form, with the femora unarmed; the tibie almost straight and rather long; the

rostrum cylindrical, curved, and received into the U-shaped mesosternum; the eyes

widely separated, and almost covered by the ocular lobes of the prothorax; the ventral

PHALIAS, gen. nov.

Rostrum very short, narrow, almost straight, the antenne inserted close to the base, with the scape short,

about as long as the first joint of the funiculus, joints 2-7 of the latter slender, short, the club ovate,

the tarsi short and narrow, with the third joint not wider than the second, the antenne

inserted close to the base of the rostram, &c. In the form of the legs Phalias

This genus includes a single species from the State of Panama. It is recognizable

by the short dilated scape of the antenne, which are inserted in the subangulate

lateral prominences of the rostrum, and near its base. The sculpture of the elytra is

rather like that of an Anchonus.

scape of the antenne in repose, the latter clavate and extending beyond the lower

limit of the eyes, the antenne themselves inserted near the base of the rostrum, with

the first joint of the funiculus clavate, and the second slender and elongate; the long,

slender tarsi, with short, narrow, deeply cleft third joint ; and the elongate, acuminate,

hairy antennal club.

Central-American specimens of this species (the type of which I have examined)

usually have a very large common dorsal patch on the elytra, and the disc of the

prothorax more or less, ochreous or fulvous, this colour in the type being almost

confined to the sete clothing the dorsal prominences. ‘The prothorax is broad, and

obtusely bidentate on each side. The vestiture is very dense, as in Collabismus.

The length varies from 4;'5-63 millim. The Colombian examples in the British

Museum have the prothorax still more dilated at the sides.

* This insect is represented by a single specimen in the Pascoe collection ; it differs from 7. encaustus in

having a shorter and broader prothorax, &c.

GRAPHONOTUS.

Graphonotus, Chevrolat, Bull. Soc. Ent, Fr. 1880, p. xevi.

Chevrolat included in this genus various Tropical-American forms, the type being

Cryptorhynchus albocaudatus, Ros., from Mexico. The name Graphonotus is here

provisionally retained for a few species agreeing in the following characters :—

Rostrum arcuate, nearly or quite reaching the metasternum, the antenne inserted at or behind the middle,

the club oblong-ovate or ovate, with the sutures very distinct in the typical forms ; head convex, the

eyes large and partly exposed ; prothorax with feebly-developed ocular lobes; scutellum visible ; elytra

wider than the prothorax; mesosternal cavity oblong or horseshoe-shaped ; metathoracic episterna

broad ; ventral segment 2 longer than 3; femora unidentate; tibie unguiculate at the outer apical

angle, the anterior pair rarely (G. albocaudatus) mucronate at the inner apical angle in the ¢; anterior

legs sometimes a little elongated in the ¢, the tarsi similarly formed in the two sexes.

G. albocaudatus, G. leporinus, G. bituberculatus, G. biolleyi, and G. maculicollis

agree very well inter se, but the other species differ from them in various details ;

(. variisquamis has the facies of a Zygops, owing to its large, subcontiguous eyes.

A common insect in Vera Cruz, and on the Atlantic and Pacific slopes of Guatemala.

It varies greatly in size. The male has the anterior femora a little longer and less

clavate than in the female; the anterior tibia, too, are feebly serrulate within, and

mucronate at the inner apical angle, as well as unguiculate at the outer angle. The

antenne are inserted behind the middle of the rostrum in both sexes. I have seen

the type belonging to the Stockholm Museum.

614 RHYNCHOPHORA.

DIAPORKESIS.

Diaporesis, Pascoe, Ann. & Mag. Nat. Hist. (5) xvii. p. 423 (1886).

This genus is based upon a single conspicuous species from Central America. It is

distinguishable by its elongate form, the comparatively long prothorax, with very

deeply bisinuate base, the oblong, oval elytra, the large eyes, strongly arcuate rostrum,

very narrow metathoracic episterna, prominent, arcuately emarginate mesosternum, &c.

The three Nicaraguan males before me have the anterior tarsi clothed with long

projecting hairs, but these are wanting in all those from Chiriqui, showing that this

character cannot always be relied upon. The males, however, may be recognized by

the depression along the middle of the metasternum and of the first ventral segment,

and also by the rather more closely punctured rostrum.

Hab. Mexico (Mus. Brit.), Toxpam in Vera Cruz (Sallé: 2); NicaRAGua (Sallé),

Chontales' (Belt: ¢ 2); Panama, Bugaba, Volcan de Chiriqui (Champion: 3 2).

Found in abundance in Chiriqui. Easily distinguished by the three white spots on

the elytra—one on the disc of each near the middle and a common oblong patch at

the apex. The dorsal spots are smaller in the Nicaraguan specimens than in those

from Mexico and Panama. A male from Chontales is figured.

PHACE, gen. nov.

Rostrum arcuate, stout, not or very little longer than the prothorax, a little widened towards the base, the antennee

(at least in the ¢ ) inserted at or beyond the middle, the funiculus 7-jointed, the club ovate ; eyes distant,

partly covered in repose; prothorax transverse, subtruncate or feebly bisinuate at the base, more or less

rounded at the sides, the ocular lobes feebly developed; scutellum very small or wanting; elytra not or

very little wider than the prothorax, in the typical forms slightly constricted at the base, the tenth row

of punctures short or evanescent (distinct to near the apex in P. striatipennis), the humeri not prominent,

subrectangular or obtuse ; mesosternum raised, prominent, arcuately or angularly emarginate in front ;

metasternum very short, the episterna moderately broad; ventral segment 2 longer than 3, usually as

long as 3 and 4 united, the intercoxal process of 1 broad, the first suture more or less arcuate ; legs

rather short, the femora unidentate or unarmed ; anterior tarsi of the males sometimes with a few fine

projecting hairs ; tarsal claws simple ; body subovate or oblong-ovate, squamose.

Type, P. pilimanus.

The various species referred to this genus are closely related to Heterobothrus, Faust

(type H. bipustulatus, from Venezuela), but differ from it in having the prothorax and

elytra less truncated at the base and the second ventral segment much longer than the

third. They have the general facies of an Acalles, from which they are separable by

their rather broadly exposed metathoracic episterna. P. leucogramma and P. striati-

pennis are somewhat divergent from the type, the others agreeing very well inter se.

Subovate, rather broad, shining, black, the antenne and tarsi more or less ferruginous ; thickly clothed with

small brown scales intermixed with very short, widely scattered, semierect, setiform, ochreous or whitish

scales, the vestiture of the scutellum ochreous, and sometimes that of the head similarly coloured. Head

densely punctate, flattened between the widely separated eyes; rostrum (3) strongly arcuate, stout,

widened towards the base, about as long as the prothorax, rugosely punctate, ( 2) sparsely punctate in its

Found in abundance at Cerro Zunil. The long hairs on the front tarsi of the

male of this species separate P. pilimanus from most of its allies. It is otherwise

recognizable by the basally constricted elytra (the anterior margin appearing a little

raised) and the finely seriato-granulate interstices.

2. Phace egena, sp.n. (Tab. XXX. fig. 14.)

Smaller and less convex than P. pilimanus; the second joint of the funiculus shorter; the elytra punctate-

striate, usually each with a small spot or transverse patch of whitish scales on the dise at the

commencement of the apical declivity ; the under surface closely punctate, the legs less elongate, the

first joint of the tarsi shorter, the anterior pair without longer projecting hairs in the d.

Six specimens. Distinguishable by the well-developed scutellum, the mottled

vestiture, and the sharply dentate femora. The males have the prothorax strongly

rounded at the sides and fully as wide as the elytra. P. scutellaris is less convex than

P. pilimanus, and its elytra are not constricted at the base.

4. Phace polochice, sp.n. (Tab. XXX. figg. 16, 16a, 9°.)

Oblong-ovate, black, the antenng obscure ferruginous ; densely clothed with pale brownish scales, with a few

darker scales intermixed, the elytra with a very faint, paler, transverse, subapical fascia, followed by a

small, oblong, black mark on the suture and a small black spot at the apex of the fifth interstice ; the

surface also set with numerous, coarse, suberect sete. Head and base of the rostrum densely, and the

rest of the latter very sparsely, punctate, the rostrum comparatively short and broad, the eyes very widely

separated; antenne inserted at the middle of the rostrum, joints 1 and 2 of the funiculus nearly equal

APTEROMECHUS.

Apteromechus, Faust, Stett. ent. Zeit. 1896, pp. 54, 82.

Apteromechus, based on a single species (A. suffrago, Faust) from Venezuela, is well

represented in Central America, and extends just over the Mexico border into Texas *.

Its chief characters are :—

Rostrum short, curved or nearly straight, in some species very rugose in the g ; eyes (except in A. scabrosus)

rather narrowly separated and in great part exposed ; the antennal club oblong-ovate or ovate ; prothorax

rounded at the sides, deeply bisinuate at the base, the median lobe partly filling the scutellar cavity, the

scutellum itself not visible, the surface coarsely, confluently punctate, the ocular lobes (except in

A. scabrosus) feebly developed ; elytra with the tenth row of punctures abbreviated, the alternate inter-

stices usually more or less raised; mesosternum prominent, feebly emarginate in front; metasternum

rather long, the episterna broad; ventral segments 2-4 subequal in length, 2 usually a little longer

than 3; femora unidentate, the anterior pair sometimes unarmed ; tibize rounded at the base externally ;

tarsi similarly formed in the two sexes or with the anterior pair clothed with projecting hairs in the 3

(A. scabrosus), the claws simple.

These insects have the general facies of Staseas, but differ from that genus in the

simple tarsal claws, &c. ‘They all have the vestiture much sparser on the prothorax

than on the elytra. The various species appear to be rare, no fewer than nine out

of the seventeen here described being represented by single examples; the Venezuelan

type, too, is unique.

decumbent seta. Head and rostrum densely punctate, the eyes widely separated, nearly covered in repose ;

rostrum short and stout, not reaching beyond the anterior coxe, feebly curved, bare at the tip, the

antennee inserted towards the apex, joints 1 and 2 of the funiculus equal in length, the others short,

the club ovate. Prothorax a little broader than long, rounded at the sides, narrowed in front, deeply

bisinuate at the base; coarsely, rugosely punctate, and feebly carinate, the ocular lobes large. Elytra

much wider than the prothorax, subparallel in their basal half, the humeri prominent ; seriate-punctate,

the interstices 3 and 5 conspicuously, and 6-9 more feebly, raised, the ridge on 3 swollen near the base.

Four specimens. In this insect the dense whitish patch on the elytra extends over

the whole of the apical declivity, as in Oxypteropsis bipartitus and Euscepes truncati-

pennis, from both of which the present species differs in having well-developed

metathoracic episterna, &c. The femora might almost be described as unarmed.

recognizable by its rather narrow, oblong elytra, which have a dark patch at the apex,

the narrowly separated eyes, and the longitudinally confluent punctuation on the

prothorax. The rostrum is smoother, more slender, and less curved than in

A. rugirostris.

Length 3,4,, breadth 13 millim. ( 2.)

Hab. Panama, Bugaba (Champion).

One specimen. A worn male (length 24 millim.) from Tapachula, Mexico (Hoge),

probably belongs to the same species; it has the rostrum rugose to the tip, the elytra

partly rufo-piceous, and the anterior femora unarmed. These examples are much

smaller than any of the allied forms, and have the prothorax and ventral segments

more shallowly punctate.

13. Apteromechus flavopunctatus, sp. n. (Tab. XXX. figg. 31, 31 a.)

distinguish this small species.

14. Apteromechus opacifrons, sp. n.

Oblong-ovate, nigro-piceous, the antenne, the rostrum (except at the base), and the tarsi in part, ferruginous ;

A. rugulifrons, but this cannot be the case. The insect is more elongate than

A. flavopunctatus, and the vestiture of the elytra is differently arranged.

17. Apteromechus leucospilus, sp.n. (Tab. XXX. figg. 30, 30a.)

Oblong-ovate, opaque, black, the antenne and the tips of the tarsi obscure ferruginous ; sparsely clothed

Hab. Guatemaa, Cerro Zunil, Purula ( Champion).

Five specimens from the Pacific, and one from the Atlantic, slope. The sharply-

defined small white spots on the elytra, which are clustered into a transverse fascia

towards the apex, the oblong, alutaceous, granulate elytra, &c., readily distinguish

A. leucospilus. The spots are reduced in size in the single example from Purula.

SEMNORRHYNCHUS.

Semnorhynchus, Faust, Stett. ent. Zeit. 1896, pp. 52, 69.

Faust referred a single species from Venezuela to this genus, which is represented

by four nearly allied forms in Central America. ‘The following are their chief

characters :—

Rostrum short, almost straight, and widened towards the base and apex; eyes distant, coarsely facetted ;

prothorax arcuately produced in front (the head scarcely visible from above), bisinuate at the base, with

feebly-developed ocular lobes ; scutellum small, but prominent ; elytra slightly wider than the prothorax,

with the alternate interstices sometimes a little raised, the tenth row of punctures abbreviated ; meso-

sternum broad, raised, and prominent, angularly or arcuately emarginate ; metathoracic episterna broad,

parallel-sided, uniseriate-punctate ; ventral segments 3 and 4 short, together very little longer than 2 ;

legs short ; femora feebly unidentate.

These insects are all of small size and oblong-ovate form, with the vestiture of the

elytra rather dense or condensed into irregular markings. The mesosternum and

rostrum are shaped very much as in Gasterocercus and its allies. |

Q 1. Elytra with the alternate interstices set with short erect scales.

1. Semnorrhynchus planirostris, sp. n. (Tab. XXXL fige. 1, 1a.)

the prothorax and two spots at the apex, and arranged in an interrupted line on each of the alternate

interstices of the elytra; the tibie fusco-annulate at the base. Head densely, rugulosely punctate, the

eyes coarsely facetted and moderately distant ; rostrum very short and stout, almost straight, widening

Hab. Mexico, Tapachula (Hége); Britisa Honpuras, Rio Sarstoon (Blancaneauz) ;

GuaTEMALA, Cerro Zunil, Capetillo, Chacoj (Champion) ; Panama, David (Champion).

Nine specimens, the two from the most northern localities belonging to the larger

form. ‘This variable insect has the rostrum straighter and more widened towards the

tip than in S. pictus, Faust. The very short sete are condensed into an interrupted

line on each of the alternate elytral interstices, as well as along the suture. The

sculpture of the prothorax is variable.

2. Semnorrhynchus tristis, sp.n. (Tab. XXXI. figg. 2, 2a.)

Very like a small example of S. planirostris, but with the vestiture of the upper surface dark brown, the

elytra with a common, narrow, sinuous, white fascia (extending outwards to the third row of punctures)

beyond the middle and an oblong black spot on the third interstice below the base ; the alternate elytral

interstices raised, and, like the suture, set with a row of very short, erect, blackish, setiform scales ; the

femora each with a minute tooth.

Length 35, breadth 12 millim. (9.)

Hab. Mexico, Jalapa (Hodge).

One specimen.

§ 2. Elytra with each interstice set with short erect scales.

3. Semnorrhynchus fulvopictus, sp.n. (Tab. XXXI. figg. 3, 3 a.)

Oblong-ovate, shining, nigro-piceous, the antenne ferruginous; sparsely clothed with brown scales, with a

few black and fulvous scales intermixed, the black scales on the elytra sometimes condensed into a small

spot on the third interstice below the base, and the fulvous ones clustered into irregular markings near

the humeri and various coalescent spots on the apical declivity ; the upper surface also set somewhat

thickly with very short erect sete ; the head with fulvous scales, the rest of the vestiture sparse, the

legs setulose. Head rugosely punctate, the eyes distant ; rostrum short, stout, widened at the base and

apex, almost straight, sparsely, rather coarsely punctate, smoother in the 2, the antenne inserted behind

the middle, joint 2 shorter than 1, 3-7 transverse, widening outwards, the club ovate. Prothorax

broader than long, rounded at the sides anteriorly, narrowed and strongly constricted in front ; coarsely,

rugosely punctate. Scutellum small, convex. LElytra a little wider than the prothorax, rather short,

subparallel in their basal half, the humeri obtuse ; with rows of coarse, subquadrate punctures, separated

by narrow, rugulose, feebly convex interstices. Beneath alutaceous, sparsely, coarsely punctate, the

ventral segments 3 and 4 almost impunctate. Mesosternum very prominent, raised, subtriangularly

emarginate. Legs short and stout; femora sharply dentate, the anterior pair very stout, and sometimes

with a small denticle exterior to the larger tooth.

Length 3-34, breadth 13-13 millim. (¢ @.)

Hab. Panama, Bugaba (Champion).

630 RHYNCHOPHORA.

Three specimens. Very like the Venezuelan S. pictus, Faust, but with the vestiture

sparser, the fulvous scales condensed into small spots on the apical declivity (and not

into a large apical patch) and some irregular markings near the shoulders; the elytral

interstices feebly convex, and each with a row of very short, erect sete (the alternate

ones being raised and setose in S. pictus). This last-mentioned character separates

S. fulvopictus from S. planirostris.

4, Semnorrhynchus fulvifrons, sp. n.

Very like S. fulvopictus, but narrower, the upper surface dull, alutaceous; the head thickly clothed with

fulvous scales in front; the rostrum coarsely, rugosely punctate to the tip; the prothorax more sparsely

and less coarsely punctate, with a very narrow impunctate space down the middle; the elytra with an

irregular, v-shaped, fulvous mark on each side at the base and several small whitish spots at the

commencement of the apical declivity, the alternate interstices somewhat raised; the under surface

alutaceous, shallowly punctate; the femora unidentate.

Length 3, breadth 12 millim. (¢.)

One specimen.

GASTEROCERCUS.

Gasterocercus, Laporte et Brullé, Mém. Soc. Hist. Nat. Paris, iv. p. 198 (1828) ; Schénherr, Gen.

Cure. iv. p. 249, and viii. 1, p. 875 (part.); Lacordaire, Gen. Col. vii. p. 118 (part.).

The Tropical-American species referred by Schénherr to this genus, the type of

which is the European G. depressirostris (Fabr.), will probably have to be separated

sooner or later. G. propugnator, G. scabrirostris, &c. agree, however, in having a

short, broad, straight, flattened rostrum, a broad, feebly emarginate, prominent

mesosternum, a short, blunt, antennal club, and large, descending eyes, and they

can be retained in Gasterocereus for the present. These forms have the anterior legs

more or less elongated, and their tarsi hairy, in the males, and the anterior femora

rather sharply unidentate in both sexes. G. plumipes and G. semicircularis, Boh.,

both of which occur in Central America, must be placed elsewhere.

The two specimens (¢ ) referred to this species agree very nearly with one before

me from Brazil, except in their smaller size; they have the rostrum more rugose

at the tip than described by Gyllenhal, but this is, no doubt, a male character.

The short granulate elevation on the first interstice just behind the scutellum is

conspicuous, ‘The anterior femora have a sharp tooth. The anterior tarsi are

clothed with long projecting hairs in the male.

A single worn female specimen from Chontales is apparently referable to this

species. It has the elytra more coarsely granulate than in G. propugnator.

The single species referred to this genus is related to Gasterocercus. It is one of

the few American Cryptorrhynchids with the anterior tarsi of the male both dilated

and ciliated.

1. Isus M-nigrum, sp.n. (Tab. XXXI. figg. 4, 4a, ¢.)

Oblong-ovate, robust, black ; densely clothed with small cinereous or whitish scales, the upper surface and

legs variegated with brown, the elytra with a common, transverse, M-shaped mark at the base, the

outer branches of which extend obliquely forwards on to the base of the prothorax, a triangular patch

at the middle of the disc of each, and a streak on the suture towards the apex, black or brownish-black,

the scutellum white. Head rugosely punctate; rostrum about as long as the prothorax, rugosely punctate

to the tip, joints 1 and 2 of the funiculus subequal in length. Prothorax abruptly narrowed and

Hab. Guatemata, San Isidro, Pacific slope (Champion).

One pair. This insect seems to be related to Cryptorhynchus rudis, Ros., from

Brazil. It has the entire surface so densely squamose that the sculpture is in great

part hidden, both above and beneath. The whitish vestiture is condensed into an

irregular X-shaped mark on the elytra and a broad median band on the prothorax.

A single species is referred to Zrachalus. Its chief characters are: the com-

paratively short fourth tarsal joint, the minute, narrowly separated claws (much as

in various Acailles), the very short, stout, feebly curved rostrum, the large, partly

exposed eyes, the deeply sinuate base of both the prothorax and the elytra, and the

minute, narrow scutellum.

is continued forwards on the base of the prothorax, and is connected posteriorly with a narrow, trans-

verse, subapical fascia and a short streak running down the suture thence to the tip; the base of the

rostrum, the narrow intraocular space, the under surface, and legs sparsely clothed with minute, narrow,

white scales, and the sternal side-pieces with a denser stripe of coarser scales. Head closely, finely

punctate ; rostrum finely, rugulosely punctate at the base, almost smooth from the middle to the tip.

The very numerous Central-American species (with a 7-jointed funiculus and visible

scutellum *) still to be dealt with, belonging to Division II. of the Cryptorrhynchides

vrais,’ are for the present placed under Cryptorrhynchus, though buat few of them can

be regarded as absolutely congeneric with the European type, C. lapathi (Linn.). The

large number of monotypic forms, and the inextricable confusion prevailing as to the

actual limits of Cryptorrhynchus (which at present includes a heterogeneous assemblage

of species from all parts of the world), Cwlosternus, and Gasterocercus, render any

other course impracticable till the Tropical-American Cryptorrhynchids are studied

as-a whole. Doubtless many more new genera will be required f.

Species of large size, convex, oblong-ovate form, thickly squamose, with the eyes covered in

repose, the rostrum curved, the antennal club ovate, the alternate elytral interstices (at

least) feebly costate, the mesosternum horseshoe-shaped, the ventral segments 2-4 equal

in length, the femora unidentate. (Nos. 1-3.)

These forms are allied to Cylindrocorynus, but they are separable from it by the ovate

antennal club, the less thickened, unidentate femora, and the widely separated eyes.

vestiture coloured as in Celosterninus longipennis, but the two insects are not otherwise

very closely related. The small scales appear to be easily abraded, about half our

specimens being worn. Prof. Biolley informs me that it is found on a species

of Melastomacew, OC. melastome will probably have to form the type of a new

genus.

CRY PTORRHYNCHUS. 639

Species moderately large, elongate, densely squamose, with the head convex, the rostrum curved,

the eyes distant and partly covered in repose, the antennal club ovate, the scutellum filling

the cavity, the prothorax bisinuate at the base, the elytra oblong, with the alternate

interstices narrowly costate, the mesosternum horseshoe-shaped, the ventral segments 2-4

equal in length, the femora unidentate. (No. 11.)

11. Cryptorrhynchus crotonis, sp. n. (Tab. XXXI. figg. 17, 174, ¢.)

Elongate, black or piceous, the antenne obscure ferruginous; densely clothed above and beneath with

intermixed pale brown and whitish scales, the latter condensed into numerous small patches on the

elytra, the entire surface also set with short, scattered, setiform scales. Head densely, rugulosely

punctate, the eyes large and widely separated ; rostrum stout, curved, about as long as the head and

prothorax, depressed at the base, densely punctate and unicarinate to about the middle, and thickly

punctate (except along the centre) thence to the apex, the apical half a little smoother in the 9, the

antennee inserted about midway, joint 2 of the funiculus shorter than 1, the club ovate. Prothorax

Length 62-83, breadth 24-33 millim. (¢ 9.)

Hab. Costa Rica, Escazu, San José (Biolley).

Five specimens, four of which are labelled as having been found on the trunk of a

Croton; one of them (evidently discoloured) has the vestiture almost entirely

brown. This insect is of about the same size and shape as Africhis occiduus, but

the vestiture is denser and not so coarse, the eyes are broader, the legs are longer

and more slender, the anterior femora are unidentate, the ventral segments 2—4 are

equal in length, &c.

Species moderately large, elongate-elliptic, sparsely squamose, with the rostrum arcuate, the

antennal club ovate, the prothorax and elytra almost equal in width, the mesosternum

horseshoe-shaped, the metathoracic episterna very broad, the ventral segment 2 longer

than 3, the femora clavate and dentate, the tibize carinate. (No. 12.)

12. Cryptorrhynchus xqualis, sp.n. (Tab. XXXI. figg. 18, 18a; 184

front leg.)

Moderately elongate, subelliptic, rather convex, shining, rufo-piceous; above uniformly clothed with small fulyous

scales, the vestiture of the abdomen very sparse, fine, and piliform, Head rugulosely, the flattened intraocular

space coarsely, punctate, the eyes large, distant ; rostrum stout, curved, reaching to about the middle of

the intermediate cox, very sparsely, minutely punctate, punctate-striate and carinate on each side at

the base, the antenne inserted at about the basal third, joints 1 and 2 of the funiculus subequal in length,

the club ovate. Prothorax broader than long, arcuately narrowing from about the middle, feebly

constricted in front, the apex somewhat produced above; densely, rugulosely punctate, the anterior lobe

smoother. Scutellum small, prominent. LElytra oblong, parallel in their basal half, very little wider

than the prothorax, produced at the apex; coarsely seriate-punctate, the interstices rugulose and

obsoletely granulate, 3-9 narrowly raised. Mesosternum very prominent, horseshoe-shaped. Ventral

segments 1-4 almost smooth, except at the sides, 5 coarsely punctate. Legs stout, short, the anterior

pair longer and more robust than the others; femora more or less clavate, unidentate, the anterior pair

with a long tooth and a small denticle exterior to it; tibia compressed and carinate, somewhat arcuate

externally.

Length 63, breadth 23 millim. (9?)

Hab. Panama, Bugaba (Champion).

One specimen. In this species the sides of the elytra (as seen from above) form an

almost continuous outline with those of the prothorax, the vestiture is uniform and

rather sparse (without intermixed sete), the anterior legs are robust, &c. An isolated

form.

Species moderately large, oblong-ovate, very densely squamose and coarsely setose, with the eyes

distant, the rostrum feebly arcuate, slightly widened towards the tip, the antenne inserted

behind the middle of the rostrum, the club ovate, the prothorax bisinuate at the base, the

elytra a little wider than the prothorax, with the third interstice swollen at the base,

the mesosternum broad, prominent, shallowly emarginate, the metathoracic episterna

moderately broad, the ventral segments 2-4 subequal in length, the femora, at most,

obsoletely dentate, the anterior tibiz and tarsi ciliate in the male. (No. 18.)

13. Cryptorrhynchus plumipes. (Tab. XXXI. figg. 19, 19a, ; 198, front

leg, 3.)

Gasterocercus plumipes, Boh. in Schénh. Gen. Cure. iv. p. 255°.

Hab. Mexico, Playa Vicente and Toxpam in Vera Cruz (Sallé: ¢ 2 ); Nicaragua,

Chontales (Janson: 2 ).—Braziu}.

Six specimens, the two males from Vera Cruz agreeing very well with Boheman’s

description of this peculiar species, recognizable at a glance by the strongly and densely

ciliate anterior tibiee of the male. The vestiture is very dense above and beneath, and

somewhat variable in colour, and the erect, blunt sete are coarse and spiniform. The

prothorax has a subquadrate brownish patch or two triangular black spots on the disc

at the base. The elytra have a brown patch on each side of the scutellum, a common,

interrupted, outwardly widened, similarly-coloured median fascia, and several black

spots, these latter scattered along the suture, sides, and base; the second interstice is

slightly raised. The rostrum of the male is rugosely punctate to the tip, that of the

female finely punctate and bare to near the base; the antenne are inserted behind

the middle in both sexes, The anterior tarsi of the male have a few projecting

hairs. The femora are obsoletely unidentate, the anterior pair sometimes unarmed,

and, like the tibie, they are often incompletely annulate with black. The length

varies from 54-74 millim. C. plumtpes should perhaps form the type of a separate

genus. It cannot be retained in Gasterocercus, the type of which is G, depressirostris

(Fabr.).

CRYPTORRHYNCHUS. 641

Species small, subovate, very densely squamose and coarsely setose, with the rostrum feebly

arcuate, the antenne inserted near its tip, the antennal club acuminate-ovate, the eyes

distant, the prothorax bisinuate at the base, the elytra very little wider than the prothorax,

comparatively short, the mesosternum broad, prominent, shallowly emarginate, the

metathoracic episterna moderately broad, the ventral segment 2 longer than 3, the femora

unidentate, the anterior tibiz and tarsi not ciliate in the male. (No. 14.)

14. Cryptorrhynchus semicircularis.

Gasterocercus semicircularis, Boh. in Schénh. Gen. Cure. viii. 1, p. 382°.

Hab. Mexico, Playa Vicente in Vera Cruz (Sal/é).—Cotompzia 1.

A single specimen ( ¢ ) from Mexico agrees very well with another before me from

Colombia. In this insect the vestiture is very dense above and beneath, and in great

part white. The elytra have a common, arcuate, blackish fascia at the middle of the

disc, and a similarly-coloured streak on each of the third and fifth interstices below

the base; the interstices 2, 3, and 5 are raised. The antenne are inserted near the

tip of the rostrum. The second joint of the funiculus is elongate, as long as the first.

The anterior tarsi are without projecting hairs. The femora are each unidentate.

The only important character it has in common with Gasterocercus is the broad,

shallowly emarginate mesosternum.

Species small, oblong-ovate, densely squamose and setose, with the rostrum short, a little

widened towards the base and apex, and almost straight, the eyes distant (small in

C. curtirostris), finely facetted, the antennal club ovate, the prothorax bisinuate at the base,

with rather prominent ocular lobes, the scutellum small, the elytra wider than the

prothorax, with the second or third interstice raised at the base, the mesosternum

prominent, feebly arcuate-emarginate, the metathoracic episterna moderately broad, the

ventral segment 2 a little longer than 3, the femora unidentate. (Nos. 15-17.)

The more finely facetted eyes and the strongly setose upper surface separate these forms

from Semnorrhynchus.

15. Cryptorrhynchus spiculosus, sp.n. (Tab. XXXI. figg. 21, 21a, 3.)

Oblong-ovate, black, the antenne and tarsi ferruginous; densely clothed above and beneath with whitish

scales, the prothorax with a broad space on the disc behind (divided down the middle and surrounding

two triangular black basal spots), and the elytra with the base and apex, and an interrupted, outwardly

widened, common, median fascia, more or less brown, the elytra also with a streak on the second

interstice at the base, and some other markings, black, the femora and tibie annulate with dark brown ;

the upper surface set with scattered, coarse, blunt, erect, light and dark sete, which on the elytra are

mainly concentrated on the alternate interstices, the legs setose. Head densely punctate, the eyes rather

large, finely facetted, widely separated ; rostrum short, stout, slightly widened towards the base and

apex, feebly curved, rugosely punctate, in the 2 more finely punctured, the antenne inserted behind the

middle, joints 3-7 of the funiculus short, 2 shorter than 1, the club stout, ovate. Prothorax transverse,

abruptly constricted and much narrowed in front; densely, finely punctate. Elytra wider than the

prothorax, subparallel in their basal half; punctate-striate, the interstices closely punctulate, 2, 4, and 6

slightly raised. Beneath densely, finely punctate. Mesosternum broad, prominent, feebly emarginate.

Femora feebly unidentate. Tibiz almost straight on their outer edge.

Length 3,,-4, breadth 14-1, millim. (¢ 9.)

Hab. Mexico, Juquila in Oaxaca (Sailé); British Honpuras, Rio Hondo

(Blancaneaur) ; Panama, Volcan de Chiriqui (Champion).

Ten specimens. Smaller and less elongate than Gasterocercus plumipes, Boh., the

brown patch at the base of the prothorax more extended, the legs not so stout, the

anterior tibie and tarsi of the male not ciliate. The white scales on the elytra form

a more or less distinct, common, X-shaped patch. The three examples from Chiriqui

may belong to a different species, as they have the elytral seta about equally distributed

over the whole of the interstices, and the rostrum of the female is much smoother than

in the specimen of the same sex from Mexico.

16. Cryptorrhynchus placatus, sp.n. (Tab. XXXI. figg. 22, 22 a, 3.)

Oblong-ovate, opaque, black, the antennew and the tips of the tarsi ferruginous; densely clothed with rather

coarse, overlapping, brownish or fulvo-cinereous scales, the prothorax with a curved streak on each side of

the disc behind (often united into one large patch), and the elytra with a broad space along the suture

at the base, partially denuded or bare, the third elytral interstice with an oval patch below the base, and

usually an irregular mark at the middle and another towards the apex, velvety-black, the upper surface

also somewhat thickly set with long, erect, blunt sete ; the vestiture of the under surface very sparse,

that of the legs close, the latter fusco-annulate and setose. Head rugulosely punctate, the eyes rather

small, distant ; rostrum short, broad, almost straight, rugosely punctate in the ¢, and more sparsely

punctate in the 9, the antenne inserted at the middle, joint 2 of the funiculus shorter than 1, 3-7 trans-

verse, the club ovate. Prothorax broader than long, constricted and abruptly narrowed in front; rather

sparsely punctate, the interspaces alutaceous. Scutellum rounded. Elytra a little wider than the prothorax,

subparallel in their basal half; seriate-punctate, the interstices alutaceous, feebly convex, flat near the

suture, 3 swollen below the base. Beneath alutaceous, sparsely, shallowly punctate. Mesosternum

prominent, feebly emarginate. Legs rather short ; femora sharply unidentate.

Length 37-43, breadth 13-2 millim. (¢ 9 .)

Hab. Panama, Volcan de Chiriqui (Champion).

_ Twelve specimens. The short, broad, almost straight rostrum, which is rugose to

the tip in the male, the black prominence at the base of the third elytral interstice,

&c., distinguish C. placatus. The elytral interstices are flatter, the sete finer, and the

tibia more rounded externally, than in C. spiculosus. The terminal (hidden) dorsal

segment of the female is tridentate.

17. Cryptorrhynchus curtirostris, sp. n. (Tab. XXXI. fige. 23, 23a.)

Oblong-ovate, shining, nigro-piceous, the elytra often in great part rufo-piceous, the antenne and the tips of

the tarsi ferruginous; densely clothed with pale brown scales, and sometimes more or less mottled or

lineate with whitish, the prothorax with two curved lines on the disc and two streaks at the apex, and

the elytra with three widely separated spots on the third interstice (the first the most conspicuous),

and sometimes a long streak on the ninth before the middle, black or blackish; the upper surface also

set with long, erect, blunt, pallid and black sete, which are clustered into a small fascicle on the third

interstice below the base ; the legs fusco-annulate and strongly setose. Head convex, densely punctulate,

the eyes rather small, widely separated ; rostrum very short and stout, widened towards the base and

apex, almost straight, flattened basally, rugosely punctate to the tip in the g, more sparsely and less

coarsely punctate in the 9, the antenne inserted at a little behind the middle, joints 3-7 of the funiculus

transverse, the club ovate. Prothorax broader than long, narrowed and feebly constricted in front;

coarsely, rather closely punctate. Elytra a little wider than the prothorax, subparallel in their basal

half, the humeri obtuse; coarsely seriate-punctate, the interstices 3, 5, and 7 more or less raised,

3 slightly swollen below the base. Beneath dull, rather finely punctate. Mesosternum very prominent,

broad, shallowly arcuate-emarginate. Legs short; femora feebly unidentate.

Length 24-34, breadth 14-13 millim. (¢ 9.)

Hab. Mexico, Motzorongo (Flohr), Teapa (Hége, H. H. Smith), Jalapa, San Juan

Bautista, Oaxaca (Hodge); British Honpuras, Belize, Rio Hondo (Blancaneauz) ;

GuATEMALA, Cahabon and Tamahu (Champion); Panama, Bugaba (Champion).

Numerous examples. The description is taken from those in the best condition,

with the sides of the prothorax and elytra lineate with whitish, the others having the

vestiture brown and the blackish markings indistinct. One from Bugaba has the sutural

region of the elytra and a space down the middle of the prothorax infuscate. The

sculpture is in great part hidden by the dense vestiture. C. curtirostris is nearly related

to C. placatus, but it is smaller, the alternate elytral interstices are raised, and the third

is a little more swollen below the base, and has two or three scattered black spots.

Species small, oblong-ovate, squamose, with the rostrum short, stout, and very feebly curved,

the eyes distant, the antennal club ovate, blunt at the tip, the prothorax bisinuate at the

base, with prominent ocular lobes, the scutellum minute, prominent, the elytra a little

wider than the prothorax, with the alternate interstices costate, the mesosternum prominent,

arcuate-emarginate, the metathoracic episterna moderately broad, the ventral segment 2

longer than 3, the first suture arched, the femora unidentate, the tooth on the anterior pair

long. (No. 18.)

Oblong-ovate, nigro-piceous, the antenne obscure ferruginous; thickly clothed with intermixed whitish and

pale brown scales, the whitish ones condensed into a median vitta on the prothorax and a common

cruciform patch on the elytra. Head rugosely punctate, flattened between the widely separated eyes ;

rostrum short, very stout, feebly curved, somewhat flattened towards the apex, rugose at the base and

thickly punctate thence to the tip, smoother in the Q, the antenns inserted behind the middle, joint 2

of the funiculus much shorter than 1, the scape short, the club ovate, blunt at the tip. Prothorax

broader than long, constricted and much narrowed in front, bisinuate at the base; densely punctate.

Scutellum minute, smooth. Elytra a little broader than the prothorax, narrowing from near the base ;

seriate-punctate, the interstices rugulose and obsoletely granulate, 3 and 5 rather strongly, and 7-9

more feebly, costate. Beneath coarsely, closely punctate. Legs rather short; anterior femora sharply,

the others moderately, unidentate ; anterior tibie sinuate within.

Length 43-5}, breadth 2-23 millim. (d 2.)

Hab. Mexico, Temax in N. Yucatan (Gaumer).

Two rather worn specimens. The common, cruciform, whitish patch on the elytra,

the minute scutellum, the broad, semicircularly emarginate mesosternum (which is

formed as in Gasterocercus), the blunt antennal club, &c., sufficiently distinguish

C. yucatanus. It is not unlike Graphonotus albescens, but has a much shorter rostrum,

644 RHYNCHOPHORA.

a shallowly emarginate mesosternum, differently marked elytra, &. The prothorax

is less sinuate at the base, and the tarsal claws are longer, than in Trachalus

micronychus. ‘The anterior tarsi of the male appear to have a few projecting, longer

hairs.

Species moderately large, robust, oblong or elongate, squamose, with the eyes large and covered

in repose, the rostrum short (except in C. octomaculatus, ?), the antennal club ovate, the

prothorax rounded at the sides and coarsely punctate, the scutellum small, the elytra

oblong, maculate, the interstices flat or convex, the mesosternum arcuate-emarginate

(horseshoe-shaped in C. octomaculatus, 2), the ventral segment 2 longer than 3, the legs

stout, the femora unidentate. (Nos. 19-22.)

These forms approach Metriophilus.

Two specimens. In this insect the light-coloured scales are condensed into a

+¢-shaped mark on the disc of the prothorax, and a large, irregular, common, X-shaped

patch on the elytra. The convex, granulate, dorsal interstices of the elytra separate it

from most of the allied forms. The tibia have a black spot on the outer edge near

Length 53-63, breadth 23-3 millim. (¢ ?.)

Hab. Panama, Bugaba (Champion).

Four specimens. ‘This is the Panama representative of the Mexican C. scopulatus,

differing from that species in its less elongate shape, the duller surface, the shorter

prothorax, the more extended dark markings of the elytra (there being no trace of the

apical patch in C. scopulatus), and the more sparsely ciliate anterior tarsi of the male.

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

Six specimens. In this insect the entire surface (the small granules on the elytra

excepted) is opaque and alutaceous. The vestiture is very sparse and rust-red in

colour, becoming fasciculate on the elytra. C. alutaceus is perhaps nearest related to

C. plagiaticollis.

Hab. Panama, Bugaba (Champion).

One pair. <A very remarkable species, with the elytral elevations, &c., formed

somewhat as in Conotrachelus cestrotus, Faust. It has no near Central-American ally,

though I have seen an undescribed Brazilian insect something like it. C. formosus

will doubtless form the type of a new genus.

Species moderately large, elongate, squamose, with the rostrum feebly curved, the eyes rather

small, the prothorax nearly or quite as long as broad, bisinuate at the base, the elytra

oblong, with elongate elevations on the disc, the mesosternum arcuate-emarginate, the

Length 5-6, breadth 2-23 millim. (¢ 9.)

Hab. Guatumaus, El Tumbador, Pacific slope (Champion).

CRYPTORRHYNCHUS. 649

One pair, in rather dirty condition. This species has the general facies of

Chetectetorus bifasciatus, Boh., an Australian insect. The two elongate ridges on

the third elytral interstice are very prominent and narrowly separated.

28. Cryptorrhynchus conspurcatus, sp. n. (Tab. XXXII. figg. 2,2a,2.)

Elongate, rather shining, black ; thickly clothed with dark greyish-brown scales, and also set with short,

scattered sete, these latter becoming longer and more crowded at the apex of the prothorax, the vestiture

long as 1, the club ovate, blunt at the tip. Prothorax fully as long as broad, feebly constricted and

gradually narrowed in front, the apex arcuately produced above, the base strongly sinuate ; coarsely

punctate, the anterior lobe minutely punctate on the disc. Scutellum oval. Elytra rather long, much

nodose, gradually narrowed in front, and with the anterior lobe longer and smoother ;

the elongate ridges on the third elytral interstice more widely separated ; the anterior

tibie not dilated within ; the second ventral] segment much shorter.

Species small, subovate, sparsely squamose, with the rostrum strongly curved, the eyes hidden

in repose by the prominent ocular lobes of the prothorax, the antennal club ovate, the

prothorax bicristate, the elytra subtriangular, with very prominent, oblong, setigerous

prominences on the disc, the mesosternum v-shaped, the ventral segment 2 nearly as long

elytral interstice with a dense, broad, oblong cluster of longer, coarse, black sete at about the middle.

Head densely punctate, subcarinate down the middle, the eyes placed low down and covered in repose ;

rostrum short, strongly curved, cylindrical, rugulosely punctate and feebly tricarinate, sparsely punctate

_ at the apex, the antenn inserted near the tip, joint 2 of the funiculus a little shorter than 1, the club

punctate. Mesosternum somewhat declivous, v-shaped. Legs short ; femora acutely unidentate ; tarsal

claws very small.

Length 3, breadth 14 millim. (<¢.)

Hab. Panama, Bugaba (Champion).

One specimen. This small species has somewhat the facies of a Conotrachelus, the

elytra having a nigro-setose crest at about the middle of the third interstice, and

the prothorax two short ridges on the disc, as in various members of that genus. The

vestiture is sparse and does not hide the sculpture. ‘The eyes are completely hidden

in repose.

Species moderately large, oblong-ovate, finely squamose, with the rostrum stout, short, and

curved, the antennal club elongate, the prothorax strongly transverse, the elytra with

smooth scattered tubercles and ten irregular rows of punctures, the mesosternum broad,

arcuate-emarginate, the ventral segments 2-4 equal in length, the anterior femora bi-, the

others unidentate. (No. 30.)

30. Cryptorrhynchus lacteicollis, sp. n. (Tab. XXXII. figg. 4, 4 a.)

Oblong-ovate, rather broad, opaque, the elytral tubercles and the under surface shining ; black, the antenner,

tarsi, and tubercles more or less ferruginous; the prothorax with a dense clothing of agglutinated, small,

- white scales, the elytra with brown scales and each with an oval velvety dark brown spot on the fourth

interstice near the base, the head, under surface, and legs with intermixed brown and white scales, the

latter clustered into small patches on the femora and tibie. Head densely, finely punctate, canaliculate

on the vertex, the eyes large, prominent, and widely separated ; rostrum exceedingly stout, curved, nearly

as long as the head and prothorax, densely, rugulosely punctate at the base, the apical half more sparsely

punctate and shining, the antenne inserted at the middle, joint 2 of the funiculus a little longer than 1,

3-7 moniliform, the club stout, oblong-ovate, acuminate, longer than the preceding five joints united.

coxe. Legs short, stout; femora strongly clavate, the anterior pair with two approximate teeth,

the others unidentate.

Length 73, breadth 33 millim. (¢.)

Hab. Mexico, Toxpam in Vera Cruz (Sallé).

One specimen only of this remarkable form has been received. The milky-white

scales on the prothorax completely hide the sculpture, and the rugulosity of the

elytra is so dense as to make the upper surface appear opaque. The anterior femora

have a conspicuous additional tooth on the outer edge of the larger one. The ocular

Tobes of the prothorax do not cover the eyes.

CRYPTORRHYNCHUS. 651

Species moderately large, oblong-ovate, convex, with the elytra, scutellum, and legs densely

squamose, the eyes very large and contiguous, the rostrum arcuate, the prothorax short,

deeply bisinuate at the base, the scutellum rather large, the elytra oblong, with the alternate

interstices raised, the mesosternum arcuate-emarginate, the ventral segment 2 much longer

than 3, the femora unidentate, the vestiture of the upper surface as in Metoposoma.

Oblong-ovate, convex, shining, black, the antennew obscure ferruginous ; the pronotum sparsely clothed with

blackish scales, with a white streak in the centre at the base, the rest of the vestiture closer and entirely

whitish, with the exception of the following markings on the elytra, which are black—a transverse

humeral patch, some irregular spots along the suture below this, a broad, common, post-median fascia,

and a transverse apical spot. Head densely punctate, the eyes very large and contiguous; rostrum

strongly curved, stout, rather longer than the prothorax, slightly widened, rugulosely punctate, and

carinate at the base, and sparsely, minutely punctate thence to the tip, the antenne inserted at the

middle, joint 2 of the funiculus a little shorter than 1, 5-7 moniliform, the club ovate. Prothorax

transverse, arcuately narrowed from the middle, and feebly constricted in front; rather coarsely,

confluently punctate, and sharply carinate. Scutellum moderately large, rounded. LElytra oblong,

considerably wider than the prothorax; coarsely seriate-punctate, the interstices rugulose, 3, 5, 7, and 9

more or less raised. Beneath sparsely punctate. Mesosternum prominent, arcuate-emarginate. Legs

short and stout ; femora unidentate ; tibize carinate.

Length 5-6}, breadth 24-3 millim.

Hah. Panama, Bugaba, Volcan de Chiriqui (Champion).

Five specimens. Very like the Guatemalan Staseas pullatus, but with larger,

contiguous eyes, a rather large, rounded scutellum, raised alternate elytral interstices,

simple tarsal claws, &c. The elytra are more densely squamose than the prothorax,

and the black markings are sharply defined; the third interstice is much raised, the

sutural region appearing depressed. The contiguous eyes, the broader prothorax, &c.,

separate C. oculeus from Metoposoma nigrofasciatum.

Species small, oblong-ovate, squamose and setulose, with the eyes large, coarsely facetted, and

narrowly separated, the antennal club elongate, the rostrum arcuate, widened towards the

base, the prothorax bisinuate at the base, the scutellum small, the cavity rather large, the

alternate elytral interstices narrowly costate, the mesosternum v-shaped, the metathoracic

episterna broad, the ventral segments 2-4 rather long, equal in length, the legs short, the

femora unidentate, the tibiz carinate, rounded externally. (Nos. 82, 33.)

32. Cryptorrhynchus ruralis, sp. n.

Oblong-ovate, robust, shining, nigro-piceous, the antenne and the tips of the tarsi obscure ferruginous ;

thickly clothed (a broad patch on the dise of the prothorax excepted) with rather coarse brown scales,

the elytra slightly mottled with black and with a few intermixed whitish scales ; the upper surface also

set with semierect, short, scattered sete. Head rugulosely punctate, the eyes transverse, large, coarsely

facetted, somewhat angular above, narrowly separated; rostrum arcuate, short, widened and rugosely

punctate at the base, and sparsely, minutely punctate thence to the tip, the antenne inserted behind the

striate, the interstices punctulate, 3, 5, 7, and 9 narrowly costate. Beneath dull, closely, rather finely

punctate. Mesosternum prominent, v-shaped. Legs short and stout; femora unidehtate ;_ tibise

carinate and somewhat rounded externally.

Length 4, breadth 2 millim. (9?)

Hab. Panama, Bugaba (Champion).

One specimen. The bare space on the prothorax is probably due to abrasion. This

species is very like some of the smaller forms here referred to Apteromechus, but

differs from them in having a well-developed scutellum, an elongate antennal club,

and an angularly emarginate mesosternum. The following is the Guatemalan

representative of it.

33. Cryptorrhynchus dorsuarius, sp. n. (Tab. XXXII. figg. 6, 6a.)

Very like O. ruralis, but a little more elongate; the vestiture darker, the elytra with small, scattered, white

spots on the middle of the disc; the prothoracic carina abbreviated; the elytra less convex, somewhat

flattened on the disc towards the base; the scutellum depressed, with a small tubercle in front; the

femora more sharply dentate; the anterior tibie slightly sinuate within.

Length 4,1,, breadth 1,9, millim. (9?)

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

One specimen. ‘The vestiture of the prothorax in this insect appears to be more

condensed at the sides and down the middle than on the rest of its surface.

Species moderately large, oblong-ovate, sparsely squamose and strongly setose, with the eyes

covered in repose, the rostrum feebly curved, the antennal club oblong-ovate, the prothorax

fasciculate, the elytra with oblong setigerous prominences on the disc and prominent humeri,

the mesosternum prominent, horseshoe-shaped, the ventral segment 2 longer than 3, the

femora unidentate. (No. 34.)

34. Cryptorrhynchus ferox, sp.n. (lab. XXXII. figg. 7,7, 3 .)

Oblong-ovate, opaque, black, the antenne fusco-ferruginous ; sparsely clothed with small fulvous scales, the

prothorax with a narrow line down the middle and another on each side beneath whitish or fulvous, the

upper surface and legs also somewhat closely set with long, coarse, erect, black and fulvous sete, the

black sets on the prothorax clustered into two fascicles at the apex, another on the median prominence,

and one on each side before the middle, and those on the elytra also becoming fasciculate on the four

dorsal elevations, the posterior two of which bear a tuft of still longer fulvous sete in front. Head

closely punctate, the eyes depressed, lateral ; rostrum feebly curved, very little longer than the prothorax,

stout, rugosely punctate and subcarinate, in the 2 smoother, shining, and not so thick, the antenne

inserted slightly beyond the middle, joint 2 of the funiculus shorter than 1, the club oblong-ovate, with

deep transverse sutures. Prothorax transversely subquadrate, very abruptly narrowed in front, bisinuate

at the base; rather sparsely, finely punctate, the disc more or less swollen in the centre. Scutellum small,

rounded. lytra much wider than the prothorax, subparallel in their basal third, flattened on the

disc anteriorly, the humeri swollen and obliquely truncated ; seriate-punctate, the interstices alutaceous,

subcostate. Ventral segments alutaceous, sparsely, finely punctate. Femora unidentate. Tibie sinuous

within.

Length 63-7, breadth 3-34 millim. (¢ 9 .)

Hab. Panama, Volcan de Chiriqui (Champion).

Four specimens. The opaque surface, the trilineate prothorax, the oblong fasciculate

prominences on the elytra, the prominent humeri, and the long, coarse, erect, abundant

setosity, give this insect a very distinct facies. he tufts of long fulvous sete on the

median elevations of the elytra project backwards, as in Metadupus apicalis.

Species large or moderately large, elongate, squamose, with the eyes large, pyriform, and almost

covered in repose, the rostrum stout and feebly curved, the antennal club elongate or oblong,

the prothorax bisinuate at the base, the elytra oblong, a little wider than the prothorax,

with the interstices granulate and the alternate ones raised, the mesosternum prominent,

arcnate-emarginate, the ventral segment 2 longer than 3, the legs rugose, the femora uni-

dentate, the anterior tarsi without projecting hairs in the §. (Nos. 35, 36.)

Celosternus frontalis, Chevr. in litt.?

Hab. Mexico, Toxpam (Sallé!); Guatrmemata, El Tumbador, Las Mercedes, Cerro

Zunil (Champion); Nicaragua, Chontales (Belt); Payama, Volcan de Chiriqui

(Champion).

Found in abundance at Cerro Zunil, and in very fresh condition, these specimens

having the transverse white subapical patch on the disc of each elytron extending

completely across and forming a common fascia. The other white markings are a spot

on the vertex, a posteriorly evanescent median vitta on the prothorax, and a curved,

elongate, humeral streak on the elytra. The antennal club is elongate. The rostrum

of the male is rugosely punctate and carinate, that of the female being smoother and

non-carinate. ‘The tarsi are clothed above with long, scattered, white hairs. Chevrolat

gives the length as 18 millim.; but this must be a mistake, the series before me

measuring from 83-12 millim. in length, and 33-5 millim. in breadth. The type

cannot be found in the Stockholm Museum; we have, however, three specimens of

the species from the Sallé collection, labelled “* Celosternus frontalis, Chevr.,” a name

that has also been used by Chevrolat for the same insect. The feebly emarginate,

prominent mesosternum, and the absence of the long, laterally projecting hairs on the

front tarsi of the male, separate C. albitarsus from the genus Cophes. A Guatemalan

specimen is figured.

36. Cryptorrhynchus cinctipes, sp.n. (Tab. XXXIL. figg. 9, 9a, 3.)

Elongate-ovate, dull, black, the antenne obscure ferruginous ; thickly clothed (except along the elytral suture)

with reddish-brown scales, with whitish scales intermixed, these latter conspicuous on the head, clustered

streak below the base and a common, interrupted, transverse, post-median fascia, the elytra also

variegated with black on the disc, the femora and tibie annulated with fuscous or black; the upper

surface set with very short, decumbent, light and dark sete. Head rugosely punctate, the eyes distant ;

rostrum stout, feebly curved, about as long as the prothorax, closely, rather coarsely punctate, rugose at

the base, and finely carinate, that of the Q sparsely, finely punctate in its outer two-thirds, the antenne

inserted at (¢) or behind (2) the middle, joints 3-7 of the funiculus transverse and closely articulated,

2 shorter tha 1, the club oblong-ovate, with oblique sutures. Prothorax transverse, narrowed and

feebly constricted in front; coarsely, closely punctate and subgranulate, except along a narrow space

down the middle. Scutellum rounded. Elytra oblong, slightly wider than the prothorax, flattened along

the suture, the humeri obtuse; seriate-punctate, the interstices rugulose and somewhat closely granulate,

3, 5,7, and 9 raised. Beneath coarsely punctate. Mesosternum prominent, arcuate-emarginate. Legs

rather stout, moderately long ; femora feebly clavate and strongly unidentate.

Length 64-8, breadth 23-33 millim. (3 9 .)

Hab. Costa Rica, San José (Biolley) ; Panama, Bugaba (Champion).

Two specimens from each locality. Very like Celosternus maculipes, Boh., from

Brazil, but with the prothorax less abruptly narrowed anteriorly, and the whitish

elytral markings more extended outwards, the elytra themselves more closely granulate.

Smaller than C. albitarsus, the legs much shorter, the antennal club less elongate, the

markings of the elytra different.

Species rather small, subovate, densely squamose and setulose, with the eyes distant aud rather

prominent, the rostrum curved, the antennal club ovate, the prothorax subtruncate at the

base and binodose on the disc, the elytra broad, with prominent, obliquely truncated humeri

and oblong setigerous prominences on the third interstice, the mesosternum raised and

feebly emarginate, the ventral segment 2 much longer than 3, the legs slender, the femora

unidentate. (No. 87.)

37. Cryptorrhynchus bivittatus, sp.n. (Tab. XXXII. figg. 10, 10a, ¢.)

Subovate, dull, black, the antenne and tarsi obscure ferruginous ; thickly clothed with brownish scales, those

on the flanks of the prothorax and on the scutellum paler, the prothorax with two broad, sinuous,

black vitte on the disc, which are continued on to the vertex, the elytra mottled with black and with a

faint, transverse, common, ochreous fascia beyond the middle; the upper surface also set with short,

scattered, semierect sete, which become fasciculate on the dorsal elevations. Head rugulosely punctate,

flattened between the widely separated, rather prominent eyes; rostrum curved, stout, about as long as

the prothorax, closely punctate, rugose and slightly widened at the base, the antenne inserted behind the

middle, joints 1 and 2 of the funiculus subequal in length, the club ovate. Prothorax transverse, con-

(the two streaks sometimes connected at the suture), whitish or cinereous, the elytra also set with short,

semierect sete; the vestiture of the under surface cinereous, that of the legs blackish and cinereous

intermixed, the femora and tibie subannulate. Head densely punctate, the eyes widely separated ;

densely punctate. The more feebly dentate femora and the very differently coloured

vestiture separate it from C. tenebrosus.

Oblong-ovate, black, the antenne and the tips of the tarsi obscure ferruginous ; mottled above with a rather

dense clothing of intermixed black, brown, and ochreous scales, the ochreous scales condensed into a

v-shaped mark at the base of the prothorax, various small scattered spots on the basal half of the elytra,

and a minute isolated spot on the disc of each towards the apex, the scutellum entirely ochreous ; the

upper surface also set with short, semierect, setiform scales; the vestiture of the legs and under surface

Elongate-ovate, black, the antennx forruginous; densely clothed above and beneath with pale brownish

scales, the prothorax and elytra with a common broad blackish space extending down the disc (which is

abruptly narrowed in front and gradually narrowed behind, and about reaches the apical declivity of the

elytra), the upper surface also set with scattered, coarse, blunt, light and dark, setiform scales, each of

the granules on the elytral coste being followed by a large raised scale, the tibiz fusco-annulate at the

base. Head rugulosely punctate, the eyes widely separated ; rostrum strongly curved, about as long as

the prothorax, widened, rugulosely punctate, and feebly carinate at the base, and minutely punctate

Length 6,5-8, breadth 23-33 millim. (9.)

Hab. Panama, Bugaba (Champion).

Three specimens. Very like Cryptorhynchus dorsalis, Ros., and similarly coloured,

but with the prothorax subparallel at the sides posteriorly; the elytra with the

alternate interstices granulate and more raised, the setiform scales coarser, the seriate

punctures finer and almost hidden by the dense vestiture ; the ventral segments 2-4

subequal in length. Siron (Ccelosternus) dorsalis, Ros., has broader metathoracic

episterna, a shorter second ventral segment, &c.

Cryptorhynchus dorsalis, Ros. in Schénh. Gen. Cure. iv. p. 101’.

Hab. Mexico, Vera Cruz (Chevrolat 1), Toxpam (Sallé).

The type of this species cannot now be found in the Stockholm Museum, but we

have received a single example from Mexico that agrees with Rosenschoeld’s descrip-

tion. It has the metathoracic episterna very narrow at the middle, as in Diaporesis.

The mesosternum is prominent, and arcuate-emarginate in front. The femora are

unidentate. The length of our specimen is 7+ millim.

72. Cryptorrhynchus eruptus, sp.n. (Tab. XXXIII. figg. 8, 2; 9, var.)

Oblong-ovate, black, the antenne and tarsi more or less ferruginous; densely clothed with whitish or pale

brown scales, the prothorax with a broad space down the middle, which is abruptly narrowed anteriorly,

and the elytra with a large transverse space at the base and another at the middle, these markings

connected along the suture, and sometimes a narrow fascia and a small spot towards the apex, black, the

femora and tibiz nigro-annulate; the upper surface also set with short, erect, black and pallid sete,

wholly black, with the exception of an irregular, interrupted, median fascia, a short streak on the

shoulder, and a few small scattered spots; the apical half of the femora and the basal half of the tibie

black ; the alternate elytral interstices less raised.

Length 44-53, breadth 2-23 millim. (d Q.) .

Hab. Muxico, Toxpam in Vera Cruz (Saillé), Jalapa (Hoge); GuaTemaLa, Cerro

Zunil (Champion).

Four specimens, the one from Jalapa belonging to the varietal form. Very near

C. dorsalis, but less elongate ; the prothorax less dilated at the sides, and with the

median carina scarcely visible ; the elytra with two large transverse black patches on

the disc, connected at the suture. The N.-American Cryptorhynchus fallax, Lec.,

seems to be a nearly allied form.

73. Cryptorrhynchus macer, sp.n. (Tab. XX XIII. fig. 10, 2.)

Oblong-ovate, shining, nigro-piceous, the antenn and the tips of the tarsi ferruginous ; thickly clothed with

cinereous scales, the prothorax with a broad, anteriorly constricted space on the disc, and the elytra with

a broad, common, transverse, subquadrate patch at the base, a transverse mark beyond the middle, and

emarginate. Femora unarmed. Tibie subangulate at the base externally.

Length 33-44, breadth 14-2 millim. (do 9.)

Hab. Guatemata, Cerro Zunil and Capetillo, Pacific slope (Champion).

Seven specimens. This insect is a close ally of C. dorsalis, with unarmed femora

and differently marked elytra. The black markings are sometimes connected by a

narrow streak along the suture, the basal one being very large and transversely

subquadrate, the second small and transverse.

74. Cryptorrhynchus sinuatipes, sp.n. (Tab. XXXIII. figg. 11, lla, 3;

11 6, hind leg, ¢.)

Oblong-ovate, black, the antenne and the tips of the tarsi obscure ferruginous; thickly clothed with rather

coarse, pale brown, overlapping scales, the prothorax with a broad, anteriorly narrowed space extending

down the middle of the disc, and the elytra with a large transverse patch at the base and a few small

spots on the apical half, black or blackish, the femora and tibis nigro-annulate; the upper surface also

set with coarse, erect, setiform scales, the legs setulose. Head densely punctate, the eyes rather large

and well-separated ; rostrum short, curved, stout, rugosely punctate, the antennee inserted at the middle;

joint 2 of the funiculus nearly as long as 1, the club ovate. Prothorax transverse, rounded at the

sides, constricted and much narrowed in front; densely punctate and feebly carinate. Elytra a little

wider than the prothorax, parallel at the base, the humeri obtuse ; seriate-punctate, the interstices 3

and 5 strongly, and 7 more feebly, raised. Beneath densely punctate. Mesosternum feebly arcuate-

emarginate. Legs short; femora strongly unidentate; posterior tibie of the g¢ deeply hollowed

towards the apex within and with the terminal claw elongated.

Length 47-44, breadth 2-23 millim. (¢.)

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

Two males. A third specimen (@?) from Chiriqui seems to belong to the same

species ; it is much smaller and has the black basal patch of the elytra extending

broadly down the suture to beyond the middle and there truncated. The peculiar

form of the posterior tibie of the male separates C. stnuatipes from C. dorsalis and

others.

75. Oryptorrhynchus medioximus, sp.n. (Tab. XXXIII. fig. 12, ¢.)

Oblong-ovate, black, the antennz and the tips of the tarsi ferrugincus; thickly clothed with dark brown

scales, with blackish scales intermixed, the elytra each with an irregular transverse ochreous fasvia at

about the middle, the femora and tibiz more or less distinctly annulate with cinereous or ochreous; the

upper surface also set with short, semierect, setiform, blackish and ochreous scales, the legs setulose.

Head densely punctate, the eyes distant; rostrum stout, curved, about as long as the prothorax, rather

sparsely punctate, the antennee inserted at a little behind the middle, joint 2 of the funiculus nearly as

long as 1, the club ovate. Prothorax broader than long, constricted and much narrowed in front,

densely punctate. Elytra a little wider than the prothorax, subparallel in their basal third, the humeri

obtuse ; seriate-punctate, the interstices 3 and 5 raised. Beneath densely punctate. Mesosternum

prominent, feebly arcuate-emarginate. Legs rugose, short ; femora obsoletely dentate.

Length 43-43, breadth 2 millim. (2.)

Hab. Guatemaa, Cerro Zunil (Champion).

Three specimens. The dark vestiture and the irregular transverse ochreous median

fascia on each elytron distinguish C. medioximus from its nearest allies. The erect

scales on the prothorax are almost entirely black, but they are not clustered into

fascicles.

76. Cryptorrhynchus tirunculus. (Tab. XXXIII. figg. 13, 134, 3.)

3. Cryptorhynchus tirunculus, Boh, in Schonh. Gen. Cure. iv. p. 68*.

Oblong-ovate, dull, black, the antennz fusco-ferruginous ; the head and prothorax sparsely, the rest of the

surface densely, clothed with sordid ochreous or whitish scales, the scales on the prothorax usually

condensed into three evanescent, interrupted lines on the disc, the elytra with a very large triangular

patch at the sides (extending from a little below the shoulder to far beyond the middle, and nearly

reaching the suture), and a common transverse patch at the base, brownish-black, the tibize near the

base and the femora at the middle and apex annulate with fuscous, the elytral interstices each with a

row of short, coarse, suberect sete, the tibie setulose; the vestiture of the abdomen in great part fuscous.

Head rugosely punctate, the eyes widely separated; rostrum short and stout, feebly curved, in the ¢

rugosely punctate and obsoletely carinate, in the Q more finely punctate, the antenne inserted at (3)

or behind (¢@ ) the middle, joint 2 of the funiculus shorter than 1, the club ovate. Prothorax trans-

verse, much narrowed in front, flattened on the disc, the sides parallel behind; densely, not very coarsely

punctate and carinate. Scutellum rounded. Elytra wider than the prothorax, subparallel in their basal

half, the humeri obtuse; seriate-punctate, the interstices rather coarsely seriato-granulate, 8, 5, and 7

conspicuously raised, 3 swollen at the base. Beneath densely punctate. Mesosternum raised and very

prominent, feebly emarginate. Legs rather stout, moderately long ; femora feebly unidentate; anterior

tarsi of the ¢ with a few, long, projecting hairs.

El Reposo, Pantaleon (Champion); Nicaracua, Chontales (Belt); Panama, David,

Bugaba, Volcan de Chiriqui (Champion).—Brazit }.

Numerous examples. The short, rugosely punctate rostrum, the very prominent,

feebly emarginate mesosternum, the strongly seriato-granulate dorsal interstices of the

elytra, the annulate legs, &c., distinguish C. ¢tirwnculus. The elytra, as described by

Boheman, have a large space at the apex, and a patch at the shoulders, ochreous or

whitish, these markings being sometimes connected along the suture.

77. Oryptorrhynchus fucatus, sp.n. (Tab. XX XIII. fig. 14, 2.)

Oblong-ovate, opaque, black, the antenne obscure ferruginous ; thickly clothed with small dark brown scales,

with a few whitish scales intermixed, the elytra variegated with black, and each with an oblique,

irregular, Y-shaped, whitish streak (extending from the shoulder to near the suture), and a transverse or

subquadrate similarly coloured patch on the disc towards the apex, the femora and tibie faintly annulate

with whitish ; the upper surface somewhat closely set with short, coarse, erect, blackish sete, the legs

setulose. Head, rostrum, and antenne much as in C. terunculus. Prothorax transverse, much narrowed

in front; densely, finely punctate, and feebly carinate. Elytra seriate-punctate, the interstices rugulose

and finely granulate, 2-9 more or less convex, 3 and 5 conspicuously raised. Beneath densely punctate.

Mesosternum raised and very prominent, feebly emarginate. Femora unidentate. Anterior tarsi without

projecting hairs in the ¢.

Length 43-64, breadth 2,5-3 millim. (¢ 9.)

Hab. Panama, Volcan de Chiriqui (Champion).

Five specimens. Near C. terunculus, but with the prothorax more finely punctate,

the elytra feebly granulate and wanting the large apical patch, the oblique whitish

humeral streak narrower and not continued down the suture, the anterior tarsi without

long hairs in the male. The vestiture of the prothorax is not sufficiently dense to hide

the punctuation.

78. Cryptorrhynchus intricatus, sp. n. (Tab. XXXIII. fig. 15, 2.)

Qblong-ovate, robust, black, the antenne ferruginous ; variegated above with a dense clothing of rather

coarse, fulvous, black, and ochreous or whitish scales, the pallid scales sometimes condensed into an

oblique interrupted streak on each elytron before the middle, and also somewhat thickly set with short,

coarse, erect, black and fulvous sete, the vestiture of the under surface and legs close and coarse, the

legs fusco-annulate and setulose. Head rugulosely punctate, the eyes pyriform and widely separated ;

rostrum short, very stout, feebly curved, densely, rugosely punctate, the apical half shining and more

CRYPTORRHYNCHUS. 67

sparsely punctate in the 9, the antenne inserted behind the middle, joints 1 and 2 of the funiculus

subequal in length, the club ovate. Prothorax transverse, rounded at the sides, rapidly narrowing from

the middle, feebly constricted in front; densely punctate and obsoletely carinate. Scutellum rounded.

Elytra much wider than the prothorax, subparallel in their basal half, the humeri obtuse ; seriate-

punctate, the interstices rugulose, and sparsely granulate, 2-9 more or less raised, 2, 3, 5, and 7

prominent. Beneath densely punctate. Mesosternum very prominent, feebly emarginate. Legs stout;

femora unidentate ; tibie sinuous within.

Length 5-63, breadth 23-3 millim. (¢ @.)

Hab. Guatemata, El Tumbador, El Reposo, Las Mercedes, Calderas, Zapote, all on

the Pacific slope (Champion); Nicaracua, Chontales (Belt, Janson).

Numerous examples. Larger and broader than C. cancellatus, the black reticulation

somewhat differently distributed; the rostrum more rugose in the male, and stouter ;

the prothorax less abruptly constricted before the middle; the second elytral inter-

stice raised; the abdomen densely punctate; the anterior tarsi of the male without

projecting hairs.

79. Cryptorrhynchus cancellatus, sp.n. (Tab. XXXIII. fig. 16, .)

Oblong-ovate, black, the antennse and the tips of the tarsi ferruginous; thickly clothed with rather coarse,

intermixed brown and cinereous scales, the prothorax and elytra more or less reticulated or variegated

with black, the elytra often with indications of a pallid median fascia, and also set with numerous short,

coarse, semierect, pallid and black sete, which are arranged in a series along each elytral interstice and

are sometimes clustered into four inconspicuous fascicles on the prothorax, the femora and tibiz fusco-

annulate and setulose. Head rugulosely punctate, the eyes pyriform, distant; rostrum about as long as

the prothorax, curved, coarsely punctate, rugose and carinate at the base and smooth along the centre

thence to the apex, the apical half more finely punctate in the 9, the antenne inserted at a little behind

the middle, joint 2 of the funiculus slightly shorter than 1, the club ovate. Prothorax transverse,

rounded at the sides, abruptly narrowed and constricted in front; densely punctate, and sometimes

obsoletely carinate. Scutellum rounded. Elytra oblong, very little wider than the prothorax, parallel

at the base, the humeri obtuse; seriate-punctate, the interstices shining and faintly granulate,

3, 5, 7, 8, and 9 raised. Beneath rather coarsely punctate, the first ventral segment slightly

depressed down the middle in the g. Mesosternum prominent, arcuate-emarginate. Femora

unidentate. Tibie almost straight on their inner edge. Anterior tarsi with a few projecting longer

hairs in the ¢.

Length 43-54, breadth 1,%-23 millim. (¢ 2.)

Eighteen specimens, varying a good deal in the colour of the scales. This is one

of several extremely closely allied variable forms, and mainly distinguishable by the

hairy front tarsi and the rather sparsely punctate rostrum of the male, the almost

straight inner edge of the tibis, and the somewhat closely nigro-reticulate elytra.

A single example ( ¢ ) from Teapa, with the vestiture blackish-brown, variegated with

black, probably belongs to the same species. A well-marked specimen from San Juan

is figured.

Hab. Mexico, Vera Cruz 2 (Chevrolat ').

The type of this species cannot now be found in the Stockholm Museum, It is

described as oblong-ovate in form, scarcely larger than the European rirrhinus

acridulus, with the vestiture brown, the prothorax with a broad pallid space at the

sides and six fascicles of erect scales on the disc; the elytra with a whitish patch at

the middle near the suture and another near the apex, the alternate interstices raised ;

the femora unidentate. C. discicollis is apparently a close ally of C. degressus.

81. Cryptorrhynchus degressus, sp.n. (Tab. XXXIII. figg. 17, 17a, 2.)

Very like C. cancellatus, but smaller; the vestiture brown or fulvous, the elytra often with indications of an

ochreous or whitish interrupted median fascia, the prothorax with six fascicles of short, erect, black set

(four across the middle and two at the apex), and two triangular black spots at the base, the sides marked

with ochreous; the elytra less variegated with black, the black scales often clustered into an irregular,

interrupted, transverse fascia below the base and another beyond the middle; anterior tibie@ sinuous, and

the others almost straight, within ; anterior tarsi of the ¢ without longer projecting hairs.

Var.? The prothorax with a space down the middle, which is abruptly narrowed anteriorly, and the elytra

‘with a broad transverse space at the base, black.

Length 3-43, breadth 13-2 millim. (d @.)

Hab. Guatemata, Senahu, San Juan, Panima, and Purula in Vera Paz, Zapote

(Champion); Panama, Bugaba, Volcan de Chiriqui (Champion).

This is perhaps an extreme form of C. cancellatus, but as the male wants the long

hairs on the anterior tarsi it seems best to treat it as distinct. C. degressus is a common

insect in Chiriqui. The variety is represented by three specimens from Vera Paz,

where the form selected as typical also occurred. Cryptorhynchus discicollis, Ros.,

from Mexico, is described as having similar fascicles of setee on the prothorax.

82. Cryptorrhynchus bioculatus, sp.n. (Tab. XXXIII. fig. 18, 3.)

Oblong-ovate, piceous, the antenne and the tips of the tarsi ferruginous; variegated above with a dense

clothing of coarse brown, whitish or ochreous, and black scales, the whitish or ochreous scales condensed

into an irregular cruciform patch on the prothorax and a large rounded or subtriangular spot at about

the middle of the disc of each elytron, the black scales on the prothorax clustered into three subtriangular

spots along each side of the ochreous median patch, and those on the elytra condensed into irregular

markings, tle suture sometimes broadly fulvous posteriorly; the upper surface also somewhat thickly

set with coarse, erect, blackish and pallid sete; the vestiture of the under surface and legs cinereous or

ochreous, the legs coarsely setose and fusco-annulate. Head ruguloscly punctate, the eyes distant ;

rostrum not longer than the prothorax, feebly curved, slightly widened towards the base, rugulosely

punctate, a little smoother in the 9, the antenne inserted behind the middle, joint 2 of the funiculus

nearly as long as 1, the club ovate. Prothorax transverse, constricted and much narrowed in front;

closely, coarsely punctate. Scutellum rounded. Elytra very little wider than the prothorax, narrowing

from about the basal third; coarsely seriate-punctate, the interstices 3 and 5 raised, the others feebly

the anterior pair often obsolete; tibie subangulate at the base externally.

Length 32-44, breadth 13-2 millim. (¢ 2.)

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

Sixteen specimens. Recognizable by the large, sharply-defined, ochreous or whitish

spot on the disc of each elytron, and the similarly-coloured cruciform patch on the

prothorax. The elytra sometimes have a broad space down the suture fulvous, this,

with the discoidal spots, forming a second cruciform patch. The sculpture is partly

hidden by the dense vestiture.

83. Cryptorrhynchus stigmatophorus, sp. n. (Tab. XXXII. fig. 19, ¢ .)

Oblong-ovate, rather narrow, piceous, the antenne and the tips of the tarsi ferruginous ; densely clothed with

moderately coarse scales, with numerous erect coarse sete intermixed; the prothorax with an interrupted

cruciform mark on the disc, the scutellum, and the elytra with a common, elongate patch—extending from

about the basal fourth to the apex, transversely or obliquely dilated anteriorly, and often constricted or

divided at the middle,—ochreous or whitish, the rest of the upper surface blackish or brown ; the vestiture

of the flanks of the prothorax, under surface, and legs paler, the legs setose and fusco-annulate. Head

rugulosely punctate, the eyes distant; rostrum rather sparsely punctate beyond the middle in both sexes.

Prothorax and elytra as in C. biocwlatus. Femora unidentate.

Many specimens, mostly rather worn. A close ally of C. bioculatus, and occurring at

the same localities in Chiriqui, but easily distinguishable when examples in good con-

dition are compared, the elytral markings being very different. ‘The common, elongate,

bidilatate, pallid apica] patch varies in extent, and is sometimes divided across the

middle, the outer anterior portions representing the discoidal spots of C. dioculatus.

84. Cryptorrhynchus distigma, sp. n.

Oblong-ovate, nigro-piceous, the antennz and the tips of the tarsi ferruginous ; variegated above with a some-

what dense clothing of fulvous and black scales, the scutellum and a small transverse patch at about the

middle of the dise of each elytron white or yellowish-white, the prothorax and elytra also set with very

short, decumbent, setiform scales ; the legs and under surface with intermixed brown and whitish scales,

the legs fusco-annulate. Head rugulosely punctate, the eyes distant; rostrum about as long as the

prothorax, rugulosely punctate at the base, and thickly punctate thence to the tip, the antenne inserted

behind the middle. Prothorax transverse, rounded at the sides, abruptly narrowed and constricted in

front; densely, rather finely punctate. Elytra slightly wider than the prothorax ; seriate-punctate, the

the third interstice and the other at the middle of the second—are characteristic. The

femora are more sharply dentate than in C. opaciventris.

101. Cryptorrhynchus senticosus, sp. n.

Oblong-ovate, shining, piceous, the elytra more or less mottled with rufo-piceous, the antenne and the tips of

the tarsi ferruginous ; thickly clothed with brown scales, sometimes with a few whitish scales intermixed,

the prothorax usually with two small patches at the base and the elytra with a few scattered spots or

streaks black or blackish; the upper surface also set with rather coarse, erect, scattered sete, the legs

setose ; the vestiture of the under surface sparse. Head densely punctate, the eyes moderately large and

well-separated ; rostrum about as long as the prothorax, curved, stout, sparsely punctate, rugulose and

slightly widened at the base, the apical half smoother in the 9, the antenne inserted at a little behind

the middle, the club ovate. Prothorax transverse, narrowed and feebly constricted in front; densely

punctate. Scutellum small. Elytra considerably wider than the prothorax, rapidly narrowing from

about the middle; punctate-striate, the interstices punctulate and feebly convex. Beneath rather sparsely

punctate. Mesosternum prominent, arcuate-emarginate. Legs short; femora feebly unidentate ; posterior

tibie similarly formed in the two sexes, not excavate at the apex in the ¢.

Length 3-34, breadth 13-13 millim. (do @.)

Hab. Panama, Volcan de Chiriqui (Champion).

Ten specimens, in rather dirty condition. An obscure species, resembling C. uncipes

in the colour of the vestiture, but smaller and narrower, the scutellum not so large, the

legs shorter, the posterior tibiz simple in the two sexes. The allied C. s¢emples is also

larger, and has larger eyes, longer legs, and the vestiture somewhat differently coloured.

The larger and more approximate eyes, the longer sete, the non-vittate prothorax, the

more sparsely punctured ventral surface, and the obsoletely dentate femora distinguish

C. senticosus from C. tectus.

102. Cryptorrhynchus contaminatus, sp.n. (Tab. XX XIII. fig. 30, 2.)

Oblong-ovate, shining, nigro-piceous, the antenne and the tips of the tarsi ferruginous; the prothorax sparsely,

the rest of the upper surface thickly, clothed with fulvous scales, the elytra with an oblique whitish streak

on the disc below the base, a broad, angulate, common, post-median, whitish fascia, and some scattered black

markings, both along the suture (before and beyond the post-median fascia) and on the disc, the scutellum

whitish ; the upper surface also set with rather long pallid and black sete; the legs setulose, the femora

subannulate. Head densely, rugulosely punctate, the eyes rather small, distant ; rostrum feebly curved,

not longer than the prothorax, widened, rugosely punctate, and subcarinate at the base, and for the rest

CRYPTORRHYNCHUS. 687

very sparsely, finely punctate, the antennw inserted beyond the middle, joint 2 of the funiculus a little

shorter than 1, the club ovate, acuminate, with deep sutures. Prothorax transverse, rounded at the sides

anteriorly, constricted and much narrowed in front; densely punctate. Scutellum rounded. LElytra a

little wider than the prothorax, narrowing from near the base, the humeri obtuse; seriate-punctate, the

interstices punctulate and sparsely, finely granulate, the alternate ones slightly raised. Beneath closely

punctate. Mesosternum raised and prominent, arcuate-emarginate. Femora unidentate.

Length 4,4,—5, breadth 2-22 millim. (¢ @.)

Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).

Two specimens, differing in the elytral markings. The above description is taken

from the female; the male has the basal half of the elytra more sparsely squamose

(leaving a very large, dense, fulvous and whitish patch on the apical declivity), and

the black mark on the suture towards the apex subtriangular, instead of elongate. The

basally dilated rostrum, &c., separate C. contaminatus from C. uncipes.

103. Cryptorrhynchus enodis, sp.n. (Tab. XXXIII. fig. 31, ¢.)

Oblong-ovate, shining, piceous, the antennee and the tips of the tarsi ferruginous ; thickly clothed with rather

coarse, intermixed pale brown, white, and fuscous scales, the white scales on the prothorax condensed

into a median line and those on the elytra into an oblique streak on the basal half of the dise and various

small scattered spots, and the fuscous (or blackish) scales into various irregular spots or streaks; the

upper surface and legs also set with numerous erect setz#. Head densely punctate, the eyes rather small

and widely separated ; rostrum not longer than the prothorax, stout, moderately curved, slightly widened

towards the base, closely, somewhat coarsely punctate, smoother in the 2, the antenne inserted at (¢)

or slightly behind (@) the middle, joint 2 of the funiculus much shorter than 1, the club ovate.

Prothorax broader than long, rounded at the sides, narrowed and feebly constricted in front; closely,

rather coarsely punctate. Scutellum rounded. Elytra a little wider than the prothorax, subparallel in

their basal third, produced at the apex, the humeri obtuse; punctate-striate, the interstices punctulate

and feebly convex. Beneath densely punctate. Mesosternum prominent, arcuate-emarginate. Legs

rather short; femora feebly unidentate.

Length 4-5, breadth 12-21, millim. (¢ @.)

Hab. Mexico, Acapulco, Tapachula (Hége); British Honpuras (Llancaneaux) ;

Panama, Caldera in Chiriqui (Champion).

One specimen from each locality, that from Caldera rather worn, but apparently

belonging to the same species. The fuscous scales are sometimes condensed into two

curved streaks on the disc of the prothorax behind. The sculpture is almost hidden

by the rather coarse vestiture. C. enodis is not unlike C. wnetpes, but the scales are

larger, the eyes are more distant, the elytra are longer and narrower, &c.

104. Cryptorrhynchus tectus, sp.n. (Tab. XX XIII. fig. 32.)

Oblong-ovate, piceous, shining, the antennee and the tips of the tarsi ferruginous ; thickly clothed with small

pale brown scales, with a few white scales intermixed (these latter condensed into two faint oblique

fascise on each elytron, a streak on the flanks of the prothorax and another in the centre at the base, and

a small spot between the eyes and another above them), the prothorax with two broad, sinuous, blackish

vittee on the disc extending from the base to the apex, and the elytra with the scutellar region and some

irregular transverse marks at about the middle also black; the upper surface set with very short, erect,

pallid and blackish sete, which on the elytra are seriately arranged down each interstice, the legs setose.

Head densely punctate, the eyes rather small, distant; rostrum short, stout, arcuate, closely punctate,

base feebly sinuate; densely, finely punctate. Scutellum small. Elytra a little wider than the prothorax,

subparallel at the base; punctate-striate, the interstices feebly convex. Beneath closely punctate.

Mesosternum prominent, feebly emarginate. Legs stout ; femora each with a short acute tooth.

Length 33, breadth 14 millim. (¢?)

Hab. Panama, Volcan de Chiriqui (Champion).

One specimen. Very like C. enodis, but much smaller, the dark vitte on the

prothorax extending to the apex, the scales smaller, the sete shorter. ‘The shorter

legs, smaller eyes, longer sete, and complete prothoracic vitte distinguish C. tectus

from C. erraticus and C. anthonomoides.

105. Cryptorrhynchus flohri, sp. n.

Oblong-ovate, rather broad, shining, black, the antenne, the apices of the tibie, and the tarsi ferruginous ;

thickly clothed with intermixed brown and blackish scales, and with a few scattered ochreous scales,

these latter condensed on the elytra into a small transverse patch near the suture beyond the middle;

the upper surface also set with scattered, black and ochreous, erect scales, the black scales condensed

into two small fascicles on the disc of the prothorax, the legs setulose; the vestiture of the under surface

pale. Head densely punctate, slightly depressed between the eyes, the latter large, separated by the

width of the rostrum; rostrum short, very stout, arcuate, rugosely punctate to the tip, the antenne

inserted at the middle, joints 3-7 of the funiculus transverse, 2 much shorter than 1, the club ovate.

Prothorax much broader than long, feebly constricted in front, the sides rounded and converging

anteriorly; densely punctate. Scutellum rounded. Elytra very much wider than the prothorax,

subparallel to the middle, flattened on the dise anteriorly, the humeri somewhat prominent, obtuse ;

rather coarsely punctate-striate, the interstices feebly convex, 3 swollen near the base and before the

middle, and 5 slightly swollen near the base only. Beneath densely punctate. Mesosternum very

prominent, raised, feebly arcuate-emarginate. Legs rather short; femora unidentate; posterior tibie

hollowed at the apex within.

Length 4,4, breadth 24 millim. (<¢.)

Hab. Mexico (ex coll. Flohr),

One rather worn specimen, labelled “ Durango,” but probably from the State of

Vera Cruz. ‘This insect has the posterior tibize formed very much as in the male

of C. uncipes, but in general appearance it is more like C. undulatus. ‘The very stout,

rugosely punctate rostrum, the widely separated eyes, the comparatively broad elytra, &c.,

separate C. flohri from most of its allies. ‘The dorsal strie of the elytra are sinuous.

106. Cryptorrhynchus phaleratus, sp.n. (Tab. XXXIV. figg. 1, 1a, 2.)

Oblong-ovate, shining, black, the antenne and the tips of the tarsi ferruginous ; sparsely clothed with small,

intermixed blackish and cinereous scales, the latter condensed into small confluent patches on the apical

half of the elytra, the head with a dense, transverse white patch in front, the scutellum also white; the

upper surface and legs somewhat thickly set with short, suberect, rather coarse, black and pallid sete ;

the vestiture of the under surface flavo-cinereous. Head densely punctate, the eyes distant and somewhat

prominent ; rostrum a little longer than the prothorax, feebly curved, rugosely punctate and slightly

widened at the base, and minutely punctate thence to the tip, the antenne inserted at about the middle,

joint 2 of the funiculus much shorter than 1, the club short, ovate. Prothorax much broader than long,

rounded at the sides, narrowed and feebly constricted in front; densely punctate. Scutellum small.

Elytra rather elongate, much wider than the prothorax, convex, parallel in their basal third, and rapidly

narrowing thence to the apex; with rows of coarse, oblong punctures placed in shallow stria, the

interstices feebly convex and sparsely punctulate. Beneath sparsely, finely punctate. Mesosternum

prominent, arcuate-emarginate, the walls declivous from the base. Legs short; femora feebly

unidentate.

Length 5, breadth 24, millim. ( 92.)

Hab. GuaTEMALA, Cerro Zunil, Pacific slope (Champion).

One specimen, apparently somewhat worn. ‘The dense white transverse patch on

the head, the shining, sparsely squamose, and coarsely setose upper surface and

legs, the rather long elytra, the sloping mesosternum, &c., sufficiently distinguish

C. phaleratus.

107. Cryptorrhynchus undulatus, sp.n. (Tab. XXXIV. fig. 2, 9.)

Oblong-ovate, shining, piceous or nigro-piceous, the antenne and the tips of the tarsi ferruginous ; somewhat

thickly clothed with moderately coarse fulvous scales, with a few blackish scales intermixed, the elytra

with a spot or short oblique streak on the fifth interstice below the base, and a narrow, angulate, post-

median fascia (of variable extent, and sometimes reduced to a few spots), white; the upper surface also

set with coarse, suberect, blackish and pallid sete, which are clustered into two small fascicles at the

apex of the prothorax, as well as along the two slightly swollen portions of the third elytral interstice ;

the vestiture of the under surface sparse and pale, the legs setulose and more or less distinctly annulate.

Head rugulosely punctate, the eyes rather prominent and well-separated ; rostrum stout, curved, very

little longer than the prothorax, slightly widened at the base, rugosely punctate and carinate, becoming

smoother towards the tip, that of the @ finely punctate beyond the middle, the antenne inserted at about

midway, joint 2 of the funiculus a little shorter than 1, the club ovate, annulate, acuminate. Prothorax

much broader than long, abruptly narrowed and constricted in front; densely punctate. Scutellum small.

Elytra much wider than the prothorax, subparallel at the base, broadly produced at the apex ; punctate-

striate, the interstices punctulate and sometimes granulate, more or less convex, 3 slightly swollen

below the base and towards the middle, and 5 also swollen below the base, the dorsal strive thus appearing

sinuate. Beneath coarsely punctate. Mesosternum much raised, very prominent, arcuate-emarginate.

Femora feebly unidentate.

Length 33-44, breadth 13-23 millim. (d 2.)

Hab. Guatemata, Cubilguitz, Senahu, and Panima in Vera Paz (Champion); Panama,

Bugaba, Volcan de Chiriqui (Champion).

Numerous examples, both from Vera Paz and Chiriqui, varying in the extent of the

angulate white fascia of the elytra, and in the number and length of the sete. The

peculiar white markings of the elytra are characteristic.

108. Cryptorrhynchus decorus, sp.n. (Lab. XXXIV. figg. 3, 3a, 2.)

Oblong-ovate, shining, nigro-piceous, the antennz and the tips of the tarsi ferruginous ; thickly clothed with

rather coarse intermixed fulvous, whitish, and black scales—the black scales condensed into two short

curved vittee on the disc of the prothorax and various spots and streaks on the elytra, and the whitish

scales into a narrow oblique humeral fascia ; the upper surface also sct with coarse, suberect, scattered

sete, which are clustered into two small fascicles at the apex of the prothorax and one on each

of the swollen portions of the third elytral interstice, the legs setulose and subannulate. Head

Hab. Panama, Volcan de Chiriqui (Champion).

Two specimens. Very near C. undulatus, and perhaps an extreme form of that

species, but with the vestiture more variegate, and the dense patches of white scales

obsolete.

109. Cryptorrhynchus collabismoides, sp. n. (Tab. XXXIV. figg. 4,

4a, 3.) |

Elongate-ovate, shining, piceous, the tarsi and antenne ferruginous ; densely clothed with small pale

brownish scales, the prothorax with a large patch on the disc, and the elytra with a space below the

base and a broad, transverse, median fascia (extending forwards to the humeri), indeterminately darker ;

the upper surface set with very short, semierect, blackish and white sete; the legs with intermixed

brownish and white scales, and also setulose. Head densely punctate, the eyes rather large and

Mesosternum prominent, arcuate-emarginate. Metathoracic episterna broad. Ventral segments closely,

finely punctate, 2 nearly as long as 3 and 4 united. Femora unidentate.

Length 54, breadth 24, millim. (<.)

Hab. Mexico (ex coll. Flohr).

One specimen. This species has much the facies of Collabismus notulatus, Boh.,

but differs from it in the well-developed scutellum, the broad episterna, the larger

and more approximate eyes, the stouter rostrum, &c. C. collabismoides approaches

C. erraticus, but it is more elongate, and has the prothorax less sinuate at the base,

the vestiture of the upper surface differently coloured, &c. The first ventral suture

is arcuate.

110. Cryptorrhynchus erraticus, sp.n. (Tab. XXXIV. fig. 5, 3.)

Obiong-ovate, piceous, shining, the antenne and the tips of the tarsi ferruginous; densely clothed with small

pale brown scales, the prothorax with two rather large black patches on the disc at the base, the elytra

somewhat closely mottled with black or fuscous on the basal half of the disc and with a few small

scattered blackish spots towards the apex; the upper surface also set with short, coarse, semierect, pallid

Hab. Mzxico, Cerro de Plumas (Hége); Guatemaua, Sinanja in Vera Paz (Cham-

pion); Panama, Volcan de Chiriqui (Champion).

A single example from each locality, agreeing very well inter se. ‘This insect

resembles C. sedulus, but it has a relatively narrower prothorax and more slender legs,

and the vestiture is not so coarse. This last-mentioned character separates C. erraticus

from Graphonotus cinctipennis and others. The strongly transverse, bimaculate

prothorax, the much shorter elytral sete, and the simple hind tibie of the male

distinguish it from C. uncipes.

111. Cryptorrhynchus anthonomoides, sp.n. (Tab. XXXIV. fig. 6, 2.)

Oblong-ovate, shining, piceous, the antenne and the tips of the tarsi ferruginous; variegated above with a

dense clothing of small brown, black, and whitish scales, the black scales on the prothorax condensed

into two short curved vitte on the disc, and those on the elytra into an irregular, interrupted, oblique

fascia before the middle, various scattered spots between this and the base, and a few other spots towards

the apex, the whitish scales clustered on the prothorax into a faint median vitta (or a spot in front of the

scutellum), an oblique streak on the disc anteriorly, and a common post-median fascia; the upper surface

also with a few, very short, scattered, decumbent, setiform scales; the vestiture of the legs and under

surface pale brown, the legs with whitish scales intermixed. Head rugulosely punctate, the eyes rather

prominent, distant; rostrum curved, about as long as the prothorax, thickly punctate, rugose and slightly

widened at the base, a little longer and smoother in the 9, the antenne inserted behind the middle,

the funiculus rather stout, joint 2 shorter than 1, the club ovate. Prothorax transverse, rounded at the

sides, narrowed and feebly constricted in front, the ocular lobes not prominent; densely, finely punctate.

Seutellum rounded. LElytra wider than the prothorax, subparallel in their basal half; seriate-punctate,

the interstices closely punctulate, becoming slightly convex towards the sides, the third a little swollen

below the base. Beneath closely, finely punctate. Mesosternum prominent, arcuate-emarginate. Legs

rather short, similar in the two sexes ; femora feebly clavate, each with a short tooth.

Length 44-5, breadth 1,%-275 millim. (¢ @-)

Hab. Guatemaua, Duefias (Champion).

always distinct. Very like Graphonotus cinctipennis and G. lituratus, but with a

much shorter rostrum and a prominent arcuate-emarginate mesosternum, the prothorax

nigro-bivittate, the elytra more mottled with black. It is a little more elongate than

C. erraticus; the upper surface is variegated with whitish or cinereous, and the

prothoracic vitte are longer and narrower.

112. Cryptorrhynchus fulvofasciatus, sp. n.

Oblong-ovate, shining, piceous, the legs and antenne rufo-piceous; the head, the prothorax with the sides,

flanks, and a narrow space down the middle, the scutellum, and the elytra with a rather broad, irregular,

Hab. Mexico, Tapachula in Chiapas, Pacific slope ({ége).

One specimen. Very like Cryptorhynchus signifer, Boh., from Vera Cruz, the type

of which I have seen, but narrower and less robust, the prothorax differently marked,

Hab. Panama, Volcan de Chiriqui (Champion).

Two specimens. In this insect the transverse white spot on the suture is very

conspicuous, owing to the unusually dark vestiture of the rest of the elytral surface.

The black markings are asymmetric.

Subovate, shining, piceous, the elytra sometimes mottled with rufo-piceous, the antenne and the tips of the

tarsi ferruginous; thickly clothed with intermixed pale brown, white, and blackish scales, the white

Hab. Guatemaa, Duefias (Champion).

Three specimens, one with the elytra more variegated with white than the others,

and the white scales tending to form two interrupted fascie on the dise. The con-

spicuous oblong cluster of short black sete at the base of the third elytral interstice

and the very feebly bisinuate base of the prothorax separate C. abjectus from various

allied forms.

Subovate, nigro-piceous, the antenne, and sometimes the tarsi and knees and tip of the rostrum also, ferru-

ginous; thickly clothed with fulvous or brownish scales, which are usually paler in colour on the apical

half of the elytra and whitish or flavo-cinereous on the base of the rostrum and the flanks of the head

and prothorax; the prothorax with two broad vitte on the disc, and the elytra with a transverse median

fascia and various markings between this and the base, black ; the upper surface also set with suberect

sete, which are seriately arranged down each elytral interstice ; the vestiture of the under surface close

_and pale, that of the legs more or less variegate. Head rugulosely punctate, the eyes very large, prominent,

and rather narrowly separated; rostrum curved, a little longer than the prothorax, widened towards the

base, thickly punctate in the ¢, smoother in the 9, the antennz inserted slightly behind the middle, the

club oblong-ovate. Prothorax rather broader than long, narrowing from near the base, densely punctate.

thorax separates C. rubicundus from its immediate allies. C. erubescens is somewhat

similar, but it has less conspicuous prominences on the disc of the prothorax, the

elytra narrowed from the base, &c.

scales on the prothorax clustered along the sides and apex, and condensed into a large subquadrate patch

on the disc, those on the elytra clustered into a transverse scutellar patch, a streak at the base of the

fifth interstice, a faint, much interrupted median fascia, and two others near the apex, the elytra also

with a narrow, oblique or transverse, blackish fascia at the sides below the base; the upper surface set with

very short, semierect sete, which are clustered into fascicles on the prothorax (four across the middle and

two at the apex); the vestiture of the abdomen coarse, close, whitish, that of the legs finer, the latter

distributed spots. Head densely punctate, the eyes very large and well-separated; rostrum arcuate,

short, sparsely punctate, rugulose at the base, the antenne inserted far behind the middle, joint 2 of the

funiculus short, the club ovate. Prothorax short, narrowing from the base, constricted towards the

apex ; densely punctate. Scutellum rounded. LElytra much wider than the prothorax, gradually

narrowing from the base, the humeri rounded and rather prominent; seriate-punctate, the interstices

punctulate, 3, 5, and 7 raised. Beneath dull, somewhat closely punctate. Mesosternum raised, very

prominent, arcuate-emarginate. Legs short; femora strongly incrassate, deeply sulcate beneath from

the base to the apex, unarmed ; tibiae broad and compressed, short.

Hab, Guatemata, Capetillo (Champion).

One specimen. Not unlike C. rubicundus, but smaller and with the vestiture

variegate, the setiform scales inconspicuous and not clustered into fascicles; the legs

shorter, the femora relatively stouter, deeply sulcate from the base to the apex, and

unarmed. This insect will certainly have to form the type of a new genus.

their outer edge.

Length 3, breadth 13 millim. (9 ?)

Hab. Panama, near the city (Champion).

One specimen. The subcylindrical shape, the truncate base of the prothorax and of

the elytra, the unarmed anterior femora, &c., distinguish this small species. ‘The

prothorax has a whitish spot in the middle at the base, and a dark patch on each

side of it. |

ULOSOMUS.

Ulosomus, Schénherr, Cure. Disp. Meth. p. 293 (1826); Gen. Cure. iv. p. 316; Lacordaire, Gen.

Col. vii. p. 100.

The few described species of this genus are all Antillean. The four now added from

our region agree in the following characters :—

Funiculus 6-jointed; eyes distant; rostrum very short and broad, almost straight, at most feebly curved,

rugose to the tip in the ¢, the antenn@ inserted at the middle; scutellum visible; metathoracic

_ episterna exposed; ventral segment 2 very little longer than 3; femora unidentate or unarmed; meso-

sternum very prominent, feebly arcuate-emarginate in front ; body squamose and strongly setose.

coarse sete arising from the dorsal prominences of the prothorax and elytra.

ULOSOMUS. 711

§ 2. Femora unarmed.

2. Ulosomus spinulosus, sp.n. (Tab. XXXV. fige. 9, 9a, 3.)

Oblong-ovate, nigro-piceous ; variegated above with a dense clothing of rather coarse, cinereous (or sordid

ochreous) and blackish spots, the pallid scales on the elytra condensed into an oblique or subquadrate

spot on the disc before the middle, an irregular, interrupted subapical fascia, and various scattered

patches; the upper surface also thickly set with coarse, erect, blackish and pallid sete ; the legs annulate

Length 23-3,1,, breadth 13-14 millim. (2.)-

Hab, Guatemaa, Chacoj in the Polochic Valley (Champion).

Two specimens, differing in the markings of the elytra, though the pallid patch on

the anterior part of the disc is conspicuous in both of them. JU. erinaceus, Boh., from

St. Bartholomew I., the type of which I have seen, differs from the present species in

having less oblong, gibbous elytra.

3. Ulosomus hispidus, sp.n. (Tab. XXXV. figg. 10, 10a, 9.)

Oblong-ovate, rather narrow, shining, piceous, the elytra mottled with rufo-piceous; variegated above with

a somewhat dense clothing of pale brown, cinereous, and blackish scales, the prothorax with two bare

patches at the base; the upper surface also thickly set with long, erect, pallid and blackish sete, the

Length 3-31, breadth 11-12 millim. (¢ 2.)

Hab. Panama, Volcan de Chiriqui (Champion).

One pair. This insect has much longer sete than U. spinulosus, and the sete are

arranged in fascicles on the disc of the prothorax and on the second elytral interstice ;

the prothorax, too, is narrower, the legs longer and not so stout, &c.

4. Ulosomus hirsutulus, sp. n.

Smaller than U. hispidus, rufo-piceous, the legs nigro-annulate; the squamosity pale brown, mottled with

fuscous, the prothorax with two curved darker patches on the posterior lobe; the blackish and pallid

sete shorter and stouter, the blackish sete clustered into a single, small fascicle at the middle of the

second elytral interstice ; the legs a little shorter, the femora unarmed ; the rostrum feebly curved.

Length 22, breadth 1 millim. (3?)

Hab. Mexico, Motzorongo in Vera Cruz (flohr).

One specimen. This species has the sete as coarse as in U. spinulosus, from which

it differs in the reiatively narrower prothorax, the less thickened legs, &c.

12. RHYNCHOPHORA.

ACAMPTOIDES, gen. nov.

Antenne inserted near the apex of the rostrum, the funiculus 6-jointed, 2-6 short, the club ovate; rostrum

very short, stout, feebly curved; head convex, the eyes rather small, distant, coarsely facetted, almost

covered in repose; prothorax arcuately projecting near the head in front, longer than broad, feebly

sinuate at the base; scutellum very small, transverse ; elytra oblong, very little wider than the prothorax,

with the tenth row of punctures abbreviated ; rostral canal closed posteriorly by the transversely raised

basal portion of the mesosternum, the sides of the mesosternal cavity not raised, the prosternal cavity

broad and deep, the anterior coxe hollowed within; metasternum rather long, the episterna narrow ;

ventral segment 2 as long as 3 and +4 united, the first suture arched; legs short and stout, femora

unarmed, tibial claw arising from the outer apical angle, tarsi with joint 3 bilobed, the claws simple ;

body elongate, narrow, densely squamose.

The type of this genus is a minute, elongate, densely squamose insect, not unlike

the North-American Acamptus and Paracamptus, but differing from them in the

6-jointed funiculus, the form of the mesosternum, &c. ‘The rostral canal might be

described as open behind, as the sides of the mesosternal cavity are not raised and

the canal is closed by the transversely raised basal portion of the mesosternum.

Acamptoides would therefore be almost equally well placed at the end of the

“ Ithyporides.”

1. Acamptoides angustus, sp.n. (Tab. XXXV. figg. 11, 11 a.)

Elongate-ovate, narrow, depressed, piceous, the elytra each with a stripe down the middle of the disc (occupying

the interstices 4 and 5), and the legs in part, rufo-piceous, the antenne ferruginous; variegated above

with a dense clothing of rather coarse, intermixed pale brown, whitish, and fuscous scales, the fuscous

scales condensed. into two spots at the base of the prothorax, the elytra each with a pallid streak down

the middle of the disc, followed by a white subapical spot; the upper surface also set with scattered,

erect, light and dark scales, the latter condensed into two small fascicles at the apex of the prothorax ;

the vestiture of the legs and under surface pale, the legs setulose. Head densely, the rostrum rugulosely,

punctate. Prothorax gradually narrowing anteriorly, densely, finely punctate. Elytra subparallel in

their basal half, finely punctate-striate, the interstices punctulate and almost flat. Beneath densely

punctate.

Length 23, breadth 1 millim. (<¢?)

Hab. GuatEMALA, Pantaleon, Pacific slope (Champion).

One specimen. ‘The sculpture in this insect is, in great part, hidden by the dense

vestiture.

TYNNICHUS, gen. nov.

Antenne inserted at about the middle of the rostrum, the funiculus 5-jointed, 2 nearly as long as 1, 3-5 short,

the club short-ovate, stout; rostrum short, almost straight, moderately stout; eyes large, narrowly

separated, coarsely facetted, somewhat angular above; prothorax transverse, strongly bisinuate at the

base, the ocular lobes feebly developed ; scutellum small, convex; elytra considerably wider than the

prothorax, with the tenth row of punctures abbreviated; mesosternum horizontal, U-shaped; metasternum

moderately long, the episterna broad ; ventral segments 1-3 subequal in length, the sutures straight and

deep ; legs rather short, anterior and intermediate femora unarmed, the posterior pair with indications

of a minute tooth, tibial claw arising from the outer apical angle, tarsi with joint 3 bilobed, the claws

simple; body subovate, narrow, convex, squamose and setose.

This genus is based upon a single species from the State of Panama. It is the first

Cryptorrhynchid described with a 5-jointed funiculus.

TYNNICHUS.—TRICHODOCERUS. 713

1. Tynnichus tenuicostatus, sp.n. (Tab. XX XV. figg. 12, 12 a, 3.)

Piceous, shining, the elytra, the anterior margin of the prothorax, and the legs rufo-piceous ; rather sparsely

clothed with fulvous scales, the elytra with a few white scales along the third and fifth interstices ; the

upper surface and legs also set with scattered, fine, suberect setae. Head densely punctate; rostrum with

the base rugulosely, and the apical half sparsely, punctate. Prothorax narrowed in front, the sides

parallel at the base; closely punctate. Elytra convex, compressed at the sides, narrowing from a little

below the base, the humeri obtuse; rather coarsely punctate-striate, the interstices 3, 5, 7, and 9 very

narrowly costate. Beneath rather coarsely punctate.

Length 34, breadth 13 millim. (9 ?)

Hab. Panama, Bugaba (Champion).

One rather worn specimen, the white scales being perhaps more numerous when the

insect is in good condition.

Sect. TRICHODOCERIDES.

This section agrees with the Old-World ‘‘ Camptorrhinides ” and the North-American

‘‘Acamptides” (Acampti, Leconte) in having the rostral canal confined to the

prosternum.

It includes a single genus from Tropical America, the structural peculiarities of

which are noticed below. The only Curculionid described with the antenne at all

similar in form is Hedycera megamera, Pasc.*, from Cayenne, which appears to be

most nearly related to Piazurus of the group “ Zygopina.”

TRICHODOCERUS.

Trichodocerus, Chevrolat, Bull. Soc. Ent. Fr. 1879, p. xcu.

The characters of this remarkable genus, incompletely given by Chevrolat, are as

follows :—

Head deeply sunk into the prothorax ; mandibles bifid at the apex ; eyes exceedingly large, somewhat coarsely

facetted, almost contiguous above; rostrum rather slender, curved, cylindrical, depressed and dilated at

the base, the scrobes short and oblique; antennz inserted close to the base of the rostrum; funiculus

7-jointed, joint 1 as stout as the scape, 2-7 very slender, long, and filiform, 3—7 gradually decreasing in

length, these latter set with one or more long projecting bristles and several very fine hairs ; club composed

of four smooth, slender, elongate joints, the tip of each of which is more or less swollen, and set with a

whorl of long scattered bristles intermixed with fine hairs ; prothorax broader than long, bisinuate at the

base, with feebly developed ocular lobes; scutellum visible ; elytra oblong, wider than the prothorax, with

ten complete rows of punctures ; prosternum raised and angularly projecting between the subcontiguous

anterior cox, the rostral canal open behind, deep, rapidly narrowed, receiving the basal portion only of

the rostrum ; metasternum long, the episterna broad; ventral segment 2 longer than 3 or 4; legs rather

short, similar in the two sexes; femora thickened, unarmed, the anterior pair sometimes with an indistinct

tooth ; tarsi with joint 3 bilobed, the claws simple.

The type, Z. spinole, inhabits Central and South America. Another species is

now added.

Hab. Costa Rica, Pozo Azul (Underwood); Panama, Bugaba (Champion).—GuIANA,

Cayenne!?; Peru (coll. Fry in Mus. Brit.).

Nine specimens, all but one from Bugaba. Dr. Aurivillius has been kind enough to

send me the two types of Chevrolat for examination, and they are certainly the sexes

of the same species. ‘The descriptions are inaccurate in several particulars *.

2. Trichodocerus brevilineatus, sp.n. (Tab. XXXV. figg. 14; 15, var.)

Elongate, narrow, piceous or rufo-piceous, the antennz (the club excepted), and sometimes the rostrum also,

on the fifth at or beyond the middle, being the most conspicuous; the vestiture of the legs cinereous or

brownish, the femora faintly fusco-annulate, that of the under surface sparse, cinereous or whitish, fine,

piliform. Rostrum shining, moderately long, slender, arcuate, minutely striato-punctate, rugulose at the

I’. spinole, the rostrum more curved, the elytra with short fuscous and cinereous

lines on the disc, the dark lines forming an interrupted median fascia and a short

scutellar streak, the alternate interstices without sete. In one immature specimen

from Bugaba the rostrum is quite smooth (except at the base) and the prothoracic

carina is wanting.

SUPPLEMENT.

Durinea the course of publication of the preceding pages various interesting forms

have been received from Costa Rica, mainly from Prof. G. Biolley and Mr. C. F.

Underwood, of San José. These are now enumerated, together with a few other

species kept back for further study or previously overlooked.

HYLOBIINA.

HILIPUS (pp. 7-49).

Amongst the four new species now added, one, H. terebrans, is a peculiar

form approaching Cholus*. The synoptic table (antea, p. 8) requires modifying

to include it :—

14(s). Hilipus rufocinctus, sp.n. (Tab. XXXV. figg. 16, 16a, ¢.)

Elongate, subcylindrical, shining, black, the prothorax (except at the base and apex), a broad annulus on the

incrassate portion of the femora, and the metasternum (except at the sides), rufous; the elytra with

various scattered whitish-ochreous spots, which are condensed into an irregular transverse fascia before

the middle and another towards the apex; the ventral segments 1-5 each with a few small white scales

on either side in front. Head almost smooth, slightly depressed between the eyes, which are well-

separated; rostrum exceedingly stout, arcuate, finely, very sparsely punctate, the antenne inserted

towards the apex. Prothorax as long as broad, subcylindrical, abruptly narrowed at the base and apex ;

716 SUPPLEMENT.

Hab. Costa Rica, Carrillo (Underwood).

One specimen. A close ally of H. belti and H. compressicollis*, differing from

both in its narrow, subcylindical form, the cylindrical prothorax, the more arcuate

rostrum, the less transverse eyes, &c. .

Hilipus stictopterus (pp. 16, 17).

To the locality given, add:—Costa Rica, Pozo Azul (Underwood).

This species was figured under the name JZ. stictecopterus (Tab. II. figg. 3, 4).

Hilipus clathratus (p. 18).

This species was figured under the name /7. venosus (Tab. II. fige. 7, 7 a).

31. Hilipus securifer, nom. n.

Hilipus securiger, antea, p. 23, t. 2. figg. 18, 18 a, 6 (nec Fauvel, 1861).

The specific name securiger being preoccupied in the genus, it is here changed to

securifer: Fauvel’s name was based upon the shape of the marking on each elytron,

while that of the Central-American insect denoted the form of the antennal club in

the male.

Hilipus phrynodes (p. 27).

To the localities given, add :—Cosra Rica, Tablazo 1700 metres (Biolley).

38 (a). Hilipus spinipennis, sp.n. (Tab. XX XV. figg. 17, 17a.)

Oblong-ovate, rather broad, dull brassy-black, sparsely clothed with small fulvous scales, the scutellum and

under surface with whitish piliform scales, the legs with intermixed whitish and fulvous scales. Rostrum

stout, feebly curved, about as long as the head and prothorax, sparsely punctate, smoother at the tip, the

antenne inserted at a little beyond the middle. Eyes large, separated by about half the width of the

rostrum. Prothorax transverse, rounded at the sides, narrowed and constricted in front, deeply bisinuate

One specimen. Near H. spiculosus, but with the conical tubercles on the elytra

mostly confined to the alternate interstices, those on 3 and 5 large and prominent, the

others small.

* Prof. Biolley has sent a specimen of this species to the British Museum ; it was found at Reventazon,

Costa Rica. H. compressicollis was described in a supplementary note on the genus Hilipus, antea,

pp. 49, 50.

RHYNCHOPHORA. 717

43 (4). Hilipus stigmosus, sp.n. (Tab. XXXV. figg. 18, 18 <.)

fiab. Costa Rica, Escazu (Underwood).

One rather worn specimen. ‘This insect somewhat resembles Sphenophorus stig-

maticus, Fahr. The velvety-black markings on the prothorax and elytra, and the

smooth interstices of the latter, readily distinguish it.

Ovate, robust, shining, black, the antenne and the tip of the rostrum obscure ferruginous, above and beneath

rather sparsely clothed with very small, narrow, white scales, which on the upper surface are condensed

into small spots on the depressed portions of the surface, the prothorax with an irregular oblique vitta on

each side, and the elytra with an interrupted subapical fascia, and two transverse spots on the outer part

of the disc between this and the base, fulvous; the legs clothed with white piliform scales. Head

sparsely punctate, foveate between the eyes, which are rather narrowly separated ; rostrum very elongate,

straight, cylindrical, moderately stout, sparsely punctate and squamose in its basal half, the apical half

much smoother, the antenne inserted at the middle, joint 1 of the funiculus elongate, nearly twice as long

as 2, the club oblong-ovate., Prothorax broader than long, rounded at the sides, narrowing from the base,

the base itself very deeply bisinuate; coarsely, shallowly, conflucntly punctate, and with an abbreviated

smooth median live, the fulvous scales (like those on the elytra) placed in closely punctate depressed

spaces. Elytra oval, with broadly rounded humeri; coarsely, irregularly seriate-punctate, the punctures

here and there transversely confluent, the interstices flat and smooth. Prosternum very deeply emarginate

with a broader femoral tooth ; tibise feebly mucronate at the inner apical angle ; tarsi broadly dilated.

Length 114, breadth 6 millim. ( 9.)

Hab. Nicaracua, Chontales (Belt).

One specimen. A remarkable species, recognizable at a glance by its very elongate,

straight rostrum (probably shorter in the ¢), non-contiguous anterior coxe, ovate

general shape, &c. The vestiture of the upper surface is rather like that of

H. longirostris.

HILIPINUS (p. 51).

2(4). Hilipinus latipennis, sp.n. (Tab. XXXV. figg. 20, 20a, 2.)

Oblong-ovate, broad, nigro-piceous; variegated above with a somewhat dense clothing of small brown,

cinereous, and black scales, the cinereous scales clustered into a line round the eyes, an oblique vitta on

each side of the disc of the prothorax, and some scattered spots on its flanks. a spot on the scutellum,

a large patch on the disc of each elytron towards the apex, a smaller patch at the apex itself, and a spot

on the shoulder, the black scales on the elytra clustered into a large, angular, sharply-defined patch on

the disc a little beyond the middle, and various small scattered spots ; the vestiture of the under surface

and legs brown slightly intermixed with cinereous. Head rugulosely punctate, the eyes somewhat

distant; rostrum very stout, a little longer than the prothorax, sulcate at the sides, rugulosely punctate

at the base, becoming much smoother towards the tip, the antenne inserted near the apex. Prothorax

strongly transverse, feebly constricted in front, the sides arcuately converging from near the base;

minutely punctate and finely granulate, and with a fine median carina. Elytra very much wider than

the prothorax, subparallel in their basal half, the humeri obtuse, the apices conjointly rounded, the

sutural angle rather sharp; closely seriate-punctate and finely granulate, the interstices somewhat

convex. Ventral segments very finely punctate.

Length 143, breadth 62 millim. (9.)

Hab. Costa Rica, Pozo Azul (Underwood).

One specimen. Near Z. laticollis, but with shorter and broader elytra, which have

each a large, angular, sharply-defined, velvety-black patch on the disc, followed by a

cluster of cinereous scales ; the prothorax relatively narrower, distinctly carinate, and

with an oblique cinereous stripe on each side, which is continued on to the humeri.

From H. lacordairet (Boh.), from Brazil, it may be distinguished by its broader

Plectromodes, Casey, Ann. N. York Acad. Sci. viii. p. 829 (1895).

Capt. Casey (Canad. Ent. 1904, p. 324) states that his genus Plectromodes, based

upon two species from the South-Eastern United States, is synonymous with

Sternechus, hitherto supposed to be confined to Tropical America.

CERATOPINA.

CATILINE, gen. nov. (to follow the genus Ceratopus, p. 126).

Rostrum stout, curved, cylindrical, about as long as the head and prothorax, the scrobes rapidly descending,

the antenne inserted at one-third from the apex, the funiculus 7-jointed, the club ovate, with deep

sutures; mandibles bifid at the tip; eyes large, descending, coarsely facetted, rather narrowly separated

above and beneath; prothorax short, with very feebly developed ocular lobes, arcuately emarginate

at the apex beneath, the space in front of the anterior cox rather broad, unimpressed; scutellum

moderately large; elytra nearly twice as wide as the prothorax, somewhat triangular, with prominent

rounded humeri; anterior coxe strongly exserted, contiguous; intermediate coxe moderately distant ;

ventral segments 3 and 4 short, together not longer than 2; legs subequal in length; femora strongly

clavate, rather slender at the base, and each armed with a large triangular tooth ; tibia narrow, feebly

sinuate, finely unguiculate at the apex; tarsi slender, joint 3 strongly bilobed, the claws with a

sharp tooth.

This genus is based upon a single species from the State of Panama, which may be

briefly described as a Conotrachelus without trace of a rostral canal. The clavate,

subpedunculate, sharply-toothed femora, and toothed tarsal claws, bring it near

Ceratopus.

RHYNCHOPHORA. 721

1. Catiline conotrachelinus, sp.n. (Tab. XXXV. figg. 22, 22a.)

Subovate, moderately shining, black, mottled with rufo-piceous; sparsely clothed with minute, narrow,

interstice conspicuous from above, the other transverse. Head densely punctate, with a small smooth

prominence above each eye; rostrum rugulosely punctate, subcarinate at the sides, much smoother at

the apex and along the middle; joint 2 of the funiculus nearly as long as 1. Prothorax strongly

transverse, bisinuate at the base, narrowed and feebly constricted in front; densely, rugulosely punctate

and obsoletely carinate. lytra narrowing from the base; rather coarsely seriate-punctate, the inter-

stices 3 and 5 interruptedly costate, the third elevation on 3 very prominent and truncate posteriorly,

7 and 8 also a little raised. Beneath closely punctate.

Subovate, shining, nigro-piceous, the antennae, the tip of the rostrum, and the tarsi ferruginous ; sparsely

clothed with small, narrow, ochreous scales, which are clustered into a spot at about the middle of the

third elytral interstice. Head rugulosely punctate, the eyes rather coarsely facetted, distant ; rostrum

stout, curved, widening outwards, about as long as the prothorax, rugulosely punctate, finely carinate

down the middle, smooth at the tip, the antennz inserted near the apex, joint 1 of the funiculus stout,

angle, and unarmed at the inner angle, the tarsal claws small, simple.

Length 4,1,, breadth 2 millim. (<¢.)

Hab. Guaremata, Senahu in Vera Paz (Champion).

One specimen. This insect is not unlike some of the smaller Conotracheli

(C. maculipes, &c.), but it has simple tarsal claws and the rostral canal is wanting.

The rostrum is formed as in Grypidiopsis, but the tibia are not mucronate at the

‘inner apical angle and the long, slender claw arises from the outer angle. ‘The species,

however, can be included in Grypidiopsis for the present.

22 SUPPLEMENT.

SMICRONYX (p. 129).

M. Bovie, of Brussels, has sent me four specimens of a species belonging to the

Pachyphanes-section of Smicronyx, apparently referable to S. discoideus, Lec.; they

are labelled ‘‘ Lerdo,” but I am not sure where this place really is, unless Villa Lerdo

in Durango is intended. Mr. Wickham, too, has sent me S. (Pachyphanes) corpulentus,

Lec., from Brownsville, Texas, a species that will certainly be found to extend across

the Rio Grande into Northern Mexico*. The Lerdo insect is much larger than

S. corpulentus, and has a stouter rostrum and a very minute scutellum. Other species

of the genus doubtless occur within our limits, many of the described forms inhabiting

Arizona, Texas, or New Mexico.

ANTHONOMINA.

ANTHONOMUS (p. 155).

16 (a). Anthonomus otidocephaloides, sp.n. (Tab. XXXV. figg. 24, 24a, 3.)

Pyriform, very shining, black, the antenne (the club excepted) obscure ferruginous ; the prothorax with three

dense lines of white, hair-like scales extending from the base to beyond the middle—the median line

continued backwards on to the scutellum, the marginal lines running downwards along the meso- and

metasternal side-pieces, the anterior coxe also clothed with narrow white scales in front, the legs with

fine white hairs. Head sparsely, finely punctate, foveate above the eyes; rostrum stout, curved, a little

longer than the head and prothorax, somewhat thickly punctate, the antenne inserted near the tip.

Prothorax convex, nearly as long as broad, narrowed in front; coarsely, closely punctate. Elytra

comparatively short, gibbous, broader than the prothorax, widening to the middle ; finely striate, the

strie feebly punctate, the interstices smooth and flat. Femora each with an acute tooth. Tibie sinuate

within, the anterior pair dilated at the middle. Tarsal claws with a long fine tooth.

Length 23, breadth 13 millim. (¢.)

Hab. Panama, Bugaba (Champion).

One specimen. Near A. aterrimus, but pyriform in shape, the prothorax with three

white lines—the median one extending on to the scutellum and the outer ones

continued down the sternal side-pieces, the rostrum shorter, the prothorax narrower,

the suture of the elytra glabrous and unimpressed at the base, the striz faintly

punctured, the anterior femora with a single tooth only.

This insect is so like an Otidocephalus that it was placed amongst the species of that

group when our collections were sorted.

Anthonomus mexicanus (p. 168).

To the localities given, add:—NortH AMERICA, Brownsville, Texas (Wickham).

We are indebted to Mr. Wickham for a North-American specimen of this widely

Anthonomus grandis (p. 186).

To the localities given, add:—Mexico, Monclova in Coahuila, Tamaulipas, Mata-

moros, San Luis Potosi, San Bartolo, Zamora, Cuernavaca, &c.; GUATEMALA, below

Tucuru in Alta Vera Paz, Peten; Cosra Rica, San José (Biolley).—Antitums, Cuba.

This insect, now known as the Mexican Cotton-boll Weevil, has of late years become

very destructive to cultivated cotton along the Rio Grande border of Texas, in

Coahuila, &c. Full reports on its life-history are given in the U.S. Dept. of Agri-

culture, Bureau of Entomology, Bulletin no. 51 (1905), &c. According to Mr. O. F.

Cook [op. cit. no. 49 (1904)], A. grandis is also injurious to the same plant in Alta

Vera Paz; he states that the adult healthy boll-weevils are destroyed by an ant, locally

called “kelep” (Ectatomma tuberculatum, Oliv.), first noticed on the cotton in the

Polochic Valley on April 20th, 1904*. Prof. Biolley has recently sent me several

specimens which were found on cotton in the garden of the Institute at San José,

Costa Rica, showing that this pest is extending southwards. Schwarz has found it in

Cuba on the “wild cotton,” Gossypium brasiliense? (cf. Proc. Ent. Soc. Wash. 1905,

pp. 13-17).

near the base, the funiculus 7-jointed—1 stouter than the scape, 2-7 short, very closely articulated,

widening outwards, 7 as wide as the ovate club, the first joint of the latter bare ; eyes prominent, pyriform,

extending narrowly downwards, finely facetted, subcontiguous above ; prothorax as long as broad, narrowed

behind, convex, deeply bisinuate at the base; scutellum oval; elytra oblong, convex, wider than the

prothorax, produced anteriorly beyond the obliquely truncated prominent humeri, finely striate; pro-

sternum very narrow in front of the anterior coxe, the latter contiguous; metasternum moderately long,

the episterna narrow ; ventral segment 2 longer than 3, all the sutures deep, the first arched, the inter-

pectinate, as in a few species of Otidocephalus.

1. Ptinopsis floccosus, sp.n. (Tab. XX XV. fige. 25, 25a, 0.)

Shining, nigro-piceous, the prothorax and elytra fusco-castaneous, the antenne and tarsi rufo-testaceous ;

above clothed with radiato-pectinate, pure white scales intermixed with very fine, long, erect, white and

fuscous hairs, the scales on the prothorax mostly clustered along the sides and base and those ou the

elytra condensed into three irregular transverse fascie, separated by barer interspaces, the fuscous hairs

clustered into a dense patch on the disc of the prothorax and occupying a transverse space across the

middle of the elytra; the sternal side-pieces densely clothed with pectinate white scales, the legs albo-

pilose. Head very finely punctate, depressed around the eyes. Prothorax swollen at the middle, sparsely,

irregularly punctate. Elytra very finely punctate-striate, the strie more deeply impressed towards the

base and shallow at the sides, the interstices almost flat. Beneath very sparsely, finely punctate.

submarginal vitta densely clothed with whitish scales, the under surface with three very broad whitish

stripes, the central one reaching the apex of the first ventral segment, the legs clothed with a few narrow

whitish scales. Head finely punctate, the eyes very large; rostrum moderately stout, curved, about as

long as the prothorax, carinate and rugulosely punctate at the base, becoming much smoother towards the

apex, the antenne inserted beyond the middle. Prothorax broader than long, rounded at the sides

posteriorly and rapidly narrowing forwards, the base very deeply bisinuate; the surface granulate.

Scutellum longer than broad. Hlytra elongate-cordate, not wider than the prothorax ; seriato-granulate

and indistinctly seriate-punctate on the disc, the punctures deep, transverse, and regularly arranged at

the sides. Mesosternum flattened between the coxw. First ventral segment broadly flattened down the

deeply bisinuate at the base, the under surface with three very broad, dense, whitish

stripes, the metasternum and ventral segments without bare spots or granules at the

sides, the outer portion of the elytra with regular rows of transverse punctures. The

whitish scales cover the whole of the under surface, with the exception of the smooth

space along the middle of the abdomen, which is continued forwards on each side

in a line with the coxe. The spaces between the granules of the upper surface are

coated with a brownish exudation. Cholus jocosus, Heller, from Colombia, is a near

ally of C. pittiert.

Cholus bipertitus, Heller, Stett. ent. Zeit. 1906, p. 21°.

Hab. Cosra Rica, San Carlos (Mus. Dresden"), Carrillo, Azahar de Cartago (Underwood).

This insect is a form of C. inwqualis *, from Chiriqui, from which it differs in having

a transverse white line, or a row of small white spots, on the elytra at about one-third

from the base, and the elytra themselves broadly flattened thence to the apex. We

have received three specimens of it (including ¢ and @), agreeing with the type

communicated by Dr. Heller.

Cholus foveolatus (p. 301).

To the Costa Rican localities given, add :—Escazu (Underwood).

Another specimen of this species is now to hand, differing from the two described in

having the squamigerous depressions on the prothorax and elytra larger and more

irregular, the seriate punctures on the latter visible between them.

clothing of small fulvous, cinereous, and dark brown scales, the cinereous scales condensed into two small

spots on the disc of the prothorax and another at each hind angle, and a small patch at the sides of the

elytra beyond the middle, the elytra also with a rather large blackish patch on the disc near the suture

about midway between the base and apex ; the vestiture of the under surface sparse, cinereous. Head

densely punctate, hollowed between the eyes, which are large, prominent, and well-separated ; rostrum

RHYNCHOPHORA. 729

arcuate, moderately long, widened at the base, dull, rugulosely punctate, and obsoletely unicarinate in

the ¢, the apical half shining and sparsely punctate in the 2, the antenn inserted at about the middle.

Prothorax short, constricted and abruptly narrowed in front; densely, finely punctate. Elytra broad,

subtriangular ; punctate-striate, the interstices rather convex, finely punctate, 2 and 3 slightly swollen

at the middle. Beneath closely punctate. Legs short; femora without distinct tooth; tarsal claws

slightly widened at the base.

Length 375, breadth 13-14 millim. (3 9.)

Hab. Mexico, Toxpam (Sailé), Cerro de Plumas (éye).

Iwo specimens, both from the State of Vera Cruz. Near 4. nigronotatus *, but

with the eyes more prominent, the head more hollowed between them, the prothorax

shorter, the elytra each with a single rather large blackish patch near the suture at

about the middle, the legs not so stout, the femora unarmed. From 4%. cavifrous

it may be distinguished by the absence of the erect sete on the elytra, the unarmed

femora, &c.
