INTRODUCTION.

Tuis Volume, one of five required for the enumeration of the Rhynchophora, was

commenced by Dr. Sharp in 1889 and is now concluded by myself. ‘The study of the

‘‘Otiorhynchine Alate”’ has unfortunately been delayed for many years, during

the publication of Vol. IV. parts 4, 5, and 7, all of which are devoted to the

Family Curculionide, The present Volume, IV. part 3, includes the Subfamilies

Attelabine, Pterocoline, Allocorynine, Apionine, Thecesternine, and Otiorhynchinee.

The Attelabine are represented by 104 (88 new), the Pterocoline by three (all new),

the Allocorynine (a new subfamily) and Thecesternine each by one, the Apionine

by 88 (84 new), and the Otiorhynchine by 419 (340 new) species respectively; the

total number for the six subfamilies being 616 species, with 516 new, and forty new

genera. Amongst the 419 Otiorhynchine, the apterous and winged forms are almost

equal in number, there being a preponderance of apterous terrestrial species

(Hupagoderes, Epicerus, Epagriopsis, &c.) in the arid portions of Mexico and the winged

forms (Laophthalmus, &c.) becoming relatively more numerous in the forest regions

southward. ‘Taking the Curculionide as a whole—the subfamilies Curculionine

and Calandrine, in addition to those worked out in the present Volume,—the

number of species enumerated altogether from Central America is as follows :—

Vol. IV. part 3, 616; IV. part 4, 1365; 1V. part 5, 908; LV. part 7, 344: total 3233.

The three other families of Rhynchophora—the Brenthide, Scolytide, and Anthri-

bide,—dealt with in Vol. IV. part 6, number 615 species, thus bringing the total

for the whole of the weevils up to 3848. ‘lhe Rbynchophora, therefore, as anticipated

(though not to the extent roughly estimated by myself in the Introduction to

Vol. IV. part 4 of this series), greatly outnumber the Phytophaga (2619, including

the Hispide and Cassidide) within our limits.

vi INTRODUCTION.

The Otiorhynchid material examined by me includes that belonging to the

U.S. National Museum, to whom we are indebted for co-types of all the species here

described from their collection, as well as for many N.-American forms for comparison.

From Costa Rica we have received during recent years numerous interesting species,

both from Pittier and Biolley. Mr. Wickham, too, during his visit to Mexico in

1909, secured various Otiorhynchids, and, as usual, has kindly allowed us to retain

any of these specimens that we required. Signor A. Solari, again, has also permitted

us to keep for the British Museum the types of such species as have been described

by me from his collection, which includes a portion of that of Jekel. The ‘ Sommer

collection” of Curculionids (including various types of Boheman, &c.) having been

recently acquired by Prof. Poulton for the Oxford University Museum, we have been

enabled to verify the names of certain species left unidentified by Dr. Sharp, and this

involves some slight corrections to the synonymy of the “ Otiorhynchine Aptere,”

which are noted in the Supplement.

As stated in a footnote on p. 317, various Apionine left undetermined by Dr. Sharp

for want of sufficient material, with such forms that have since come to hand, have

been handed over to the specialist Herr Hans Wagner for study, and his descriptions

of the new forms will be published elsewhere.

Of the fifteen coloured Plates issued, the first six were drawn by Mr. Purkiss, the

others by Mr. E. Wilson of Cambridge.

It will not be out of place to note here that the enumeration of the Coleoptera,

commenced in 1879, is now completed, bringing the total number of species to 18,039,

for which eighteen Volumes have been required.

Attelabus is at present a genus of more than 100 species, distributed over the

continental regions of the world, and no doubt numerous in the tropics, as there are

many undescribed species extant in collections. South America and the Antilles have

yielded at present the larger proportion of its representatives.

Bedel! has recently proposed to transfer the name AZtelabus to the allied genus

Apoderus, on the ground that in the tenth edition of the ‘Systema Nature’ an insect

now referred to Apoderus was the representative of Attelabus. In the Munich

Catalogue, which I here follow, the origin of the genus is assigned to the twelfth

edition of the ‘Systema Nature’; or the genus may be credited to Olivier, whose

work really inaugurated the modern arrangement of the genus and its allies. Hither

course appears sufficiently satisfactory, and enables us to avoid the confusion caused

by Bedel’s proceeding [which involves the alteration of some hundreds of names of

species of Curculionide— Apoderus being called Attelabus, Attelabus Chyphus (emended

to Cyphus), and Cyphus Neocyphus|, so that I have no doubt the course I now adopt

will receive the sanction of Coleopterists.

Attempts have been made in a more or less distinct manner to subdivide the genus;

but the divisions have not proved satisfactory, and I follow Lacordaire and the Munich

Catalogue in using the name in its more extended sense.

I. Anterior femora without teeth or spines. (Attelabus, auct.)

A. Eyes very widely separated, the space between them not carinate ; spurs of the

anterior tibie of the female placed one in front of the other. (Pilolabus, Jekel.)

AMERICA |.

We have received only three examples, all females, that I can refer to this species ;

this sex has the peculiarity that the front tibie are bimucronate at the extremity,

the mucrones being placed at the inner edge, one in front, the other behind.

Attelabus sumptuosus has hitherto been only recorded from South America, but I feel

sure that this has been the result of error. Gory ! says, “ cette charmante espéce a été

trouvée dans l’Amérique méridionale, et m’a été donnée par M. Children de Londres.”

Now the two examples of the species in the collection of the British Museum are also

from Children’s collection and are labelled Mexico, so that it is highly probable that

Gory’s example was really from there ; this appears more certain when we recollect

how vague is the term “ Amérique méridionale ” used by Gory.

2. Attelabus viridans. (4. viridanus, Tab. I. figg. 1, 1 a.)

Attelabus viridans, Gyll. in Schénh. Gen. et Spec. Cure. v. p. 303°.

Hab. Mexico, between Oaxaca and Acapulco !, Cuernavaca (Sallé).

If I rightly apply this description, A. viridans is very closely allied to A. swmptuosus,

and differs chiefly in the coarser sculpture of the wing-cases. It is apparently very

variable in colour, some specimens being in this respect similar to A. sumptuosus, while

others are blue or green, without copper or golden stripe ; I think, however, all belong

to one species, though this is by no means certain. The structure of the front tibie

of the female is the same as in 4. swmptuosus.

This is apparently a rare insect, as our editors have received only five examples, and

I am acquainted with only two or three others in the collections of the Rev. H. 8.

Gorham and myself, obtained from old sources.

8. Attelabus smithi, sp. n.

Subtus viridi-auratus, supra cupreus, prothoracis basi elytrorumque viridis, antennis pedibusque nigris ; elytris

fortiter profundeque punctatis.

Long. cum rostro 8 millim.

Hab. Mexico, Mescala in Guerrero (HZ. H. Smith).

ATTELABUS. 3

Antenne very short, the fourth joint a little longer than broad, the sixth about as long

as broad, the seventh and eighth transverse, the club abrupt, compact, about as long

as the five preceding joints, the tenth joint rather shorter than the ninth or eleventh.

Rostrum short and broad, only as long as the head; eyes prominent, widely separated,

the surface between them rugose. Thorax narrower in front than behind, constricted

both in front and at the base. Elytra with a series of deep punctures, subrugose, not

brilliant even at the apex.

We have received only two female examples of this species. One of the varieties of

A. viridans is almost similarly coloured, but I separate A. smitht on account of its

smaller size and still coarser and deeper sculpture. The cupreous-red parts of A. smithi

are duller in colour than in A. swmptuosus and A. viridans, var., and the legs have

scarcely any metallic tint.

4. Attelabus splendens. (Tab. I. fig. 2, ¢.)

Attelabus splendens, Gyll. in Schéuh. Gen. et Spec. Cure. v. p. 304".

Hab. Mexico, Vera Cruz (Chevrolat !, Sallé).

I have seen only two examples of this species. The female has the front tibie

bimucronate, the mucrones being placed similarly to those of the same sex of A. vir-

dans and A. sumptuosus; the mucrones, however, are much smaller in A. splendens,

and the tibia is shorter and stouter and the crenulations on its inner face are much

less marked. The male is in an immature and mutilated condition, and has onlya

single small mucro on the front tibie.

5. Attelabus klugi, (Tab. I. fig. 3,4.)

Attelabus klugii, Gyll. in Schénh. Gen. et Spec. Cure. v. p. 302°.

Hab. Mexico (Klug), Parada (Sal/é).

6. Attelabus nigriclava, sp. n.

Gracilis, eneus, rugosus, griseo-pubescens, antennarum clava nigerrima, elytris singulis puncto depresso fusco.

Long. cum rostro 7 millim.

Hab. Mexico, Chilpancingo in Guerrero 4600 feet (H. H. Smith).

Var. Elytris minus profunde rugosis, quasi submaculatis; minus conspicue griseo-pubescens.

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

Antenne moderately long, the club abrupt, quite black and thus contrasting strongly

with the other joints, as these bear much white hair. Head as long as the rostrum;

eyes prominent, widely separated. Thorax much narrowed towards the front, but not

constricted either in front or at the base, deeply transversely rugose. Scutellum

narrow. Elytra rather deeply and coarsely rugose; on the middle of each is a small

round fovea. Legs slender. Male with a depression along the middle of the ventral

segments.

We have received five examples of this species, which is allied to A. klug?, but

differs in a great many minor points, besides the foveze on the wing-cases. Of the

variety we have received only one specimen. It is quite possible that it may prove to

be a distinct species.

7. Attelabus diffinis, sp. n.

Gracilis, nigerrimus, brevissime parcissimeque pubescens, subopacus; elytris obsolete sculpturatis.

Long. cum rostro 9 millim.

Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith, June 1888).

Head elongate, about as long as the rostrum, the eyes convex, very widely separated,

the space between them without depressions, rugosely sculptured. Thorax elongate,

rounded at the sides and a little narrowed in front, with a feeble depression or constric-

tion in front of the base, the surface transversely rugose. Scutellum narrow and quite

small. Elytra elongate, with a distant, very irregular punctuation. Legs long and

slender.

This insect has the form of A. klugi, but is very different in colour, sculpture, and

pubescence. Only one example has been obtained; it is a female, and has the two

spurs on the anterior tibize placed one in front of the other as in A. viridans.

B. Eyes only moderately distant, the space between them carinate ; surface pubesceit ;

spurs of the anterior tibie of the female placed one above the other. (Himatolabus,

Jekel.)

8. Attelabus vestitus.

Attelabus vestitus, Gyll. in Schénh. Gen. et Spec. Cure. v. p. 307’.

Hab. Mexico, between Oaxaca * and Acapulco !, Oaxaca (Hége), Yolos (Sadlé).

Var. duplo minor.

Hab. Mexico, Ciudad in Durango, Zacualtipan in Hidalgo (/ége).

The sexual distinctions, except in the front legs, are not conspicuous in this species ;

the female has the armature of these parts very strongly developed, the upper of the

two apical mucrones being of unusual size.

The unique exponents from Ciudad and Zacualtipan may not be really conspecific ;

they by no means agree with one another, however, and if distinct from 4. vestitus

must represent two closely allied species.

* Schonherr writes in this and other cases “‘ Oaxara”; but as there can be little doubt that Oaxaca is intended

I shall make this change whenever I have occasion to quote the locality from him.

9. Attelabus rudis.

Aitelabus rudis, Boh. in Schénh. Gen. et Spec. Cure. viii. p. 360°.

Hab. Mexico (Sturm).

This may possibly be a small variety of the female of A. vestitus.

10. Attelabus vinosus, sp. n.

Rufo-obscurus, pube pallescente sat dense vestitus; prothorace elytrisque fortius sculpturatis; scutello sub-

quadrato, haud transverso.

Long. 53 millim.

Hab. Mexico, Totosinapam, Capulalpam (Sallé), Jalapa (H6ége); GUATEMALA, Quiche

Mountains 7000 to 8000 feet (Champion).

Closely allied to A. vestitus, but distinguished by the dark vinous-red colour

and the much more evident sculpture. The sexual distinctions, except in the front

legs, are slight. The rostrum is quite short, thick, the head broad, the eyes placed

nearly midway between the front of the thorax and the mouth. The thorax is rather

coarsely and irregularly sculptured, without any transverse groove. The elytra are even,

scarcely at all depressed behind the scutellum, rather coarsely and irregularly sculptured,

the striation quite visible. The front femora are entirely unarmed.

A specimen of this species in Sallé’s collection from Sturm’s cabinet is labelled

A. cinnamomeus, Sturm; but as this name is not a suitable one—being much more

applicable to the closely allied A. vestitus—I have not used it. The four Mexican

examples before me are all in a bad state of preservation ; the description therefore is

taken from the Guatemalan exponents, six in number.

11. Attelabus axillaris. (Tab. I. fig. 4, 2.)

Attelabus axillaris, Gyll. in Schonh. Gen. et Spec. Cure. v. p. 308°.

Hab. Mexico, between Oaxaca and Acapulco !, Parada, Yolos (Sal/é), Playa Vicente

(Hoge); GUATEMALA, near the city, San Gerénimo (Champion).

This insect shows considerable variation in size and sculpture, but I believe the

nine examples before me really represent one species. In some specimens the front

tibize are bimucronate at the apex; these I consider to be females.

C. Eyes but little separated, the space between them sulcate or carinate ; surface

without pubescence. (Xestolabus, Jekel.)

12. Attelabus heterocerus, sp. n.

Nudus, nigerrimus, nitidus, elytris singulis plaga magna humerali rufa; antennis articulis 2°-8™ piceis, clava

elongata sed cum articulo ultimo minuto.

Long. cum rostro 5 millim.

Hab, Mexico, Amula and Chilpancingo in Guerrero (H. AH. Smith).

6 RHYNCHOPHORA.

We have received only two examples of this insect; they are males, and the pecu-

liarity of the antenne by which the species may be distinguished from all others of the

genus is perhaps less marked in the other sex—the ninth and tenth joints are each

about as long as the four preceding joints together, while the terminal joint is small and

acuminate, and subconstricted in the middle. In general form A. heterocerus somewhat

resembles A. corvinus, but it has a more conical thorax. The head is elongate, and the

rostrum short, hardly so long as the head; the eyes only moderately convex, rather

widely separated, the space between them depressed, feebly carinate in the middle.

Thorax rather long, subconical, almost smooth, there being only a slight sculpture

along the base. Elytra with a subobsolete, rather scanty, diffuse punctuation, and also

with series of fine, distant punctures, quite obsolete towards the apex ; the sutural series

is more distinct than the others, but does not reach the apex, and the outer series are

so indistinct that they can scarcely be perceived even at the base. The scutellum is

much narrower than it is in A. corvinus.

13. Attelabus corvinus.

Attelabus corvinus, Gyll. in Schénh. Gen. et Spec. Cure. v. p. 304°.

Hab. Mexico, between Oaxaca and Acapulco}, Atoyac in Vera Cruz (H. H. Smith),

Ventanas in Durango, Juquila, Tapachula (Hoge), Toxpam (Sallé); British Honpuras,

R. Hondo (Blancaneaux); GuatemMata, El Tumbador, Las Mercedes, Cerro Zunil,

Zapote, Capetillo, Duefias, Purula, Chacoj (Champion), Panzos (Champion, Conradt),

Coban (Conradt) ; Nicaragua, Chontales (Belt); Cosra Rica (Van Patten) ;

Panama, Volcan de Chiriqui 3000 feet (Champion).—Soutn America, Colombia (coll.

Gorham).

There are important differences between the sexes of this species, the front legs and

the thorax, and the various parts of the head, including even the eyes and the antenne,

being longer in the male than in the female: in the former sex the strongly curved

front tibie have a single mucro at the apex, and the apex of the rostrum is strongly

bidenticulate beneath ; in the female the front tibize are bimucronate.

A. corvinus appears to be abundant in Guatemala, but from Mexico we have received

only seven examples, and only a single individual from each of the more southern

provinces.

14. Attelabus lesicollis. (Tab. I. figg. 5, 5a, ¢.)

Aitelabus lesicollis, Gyll. in Schénh. Gen. et Spee. Cure. v. p. 305°.

Hab. Mexico (coll. Chevrolat+), Tacambaro, Acapulco (fége); GuaremaLa, San

Geronimo (Champion).

Gyllenhal’s description was taken from one male example, and the characters he

gives are in part applicable only to that sex. A. lwsicollis in both sexes may be dis-

ATTELABUS. 7

tinguished from A. corvinus by the smaller size, by the elytra being feebly tinted with

blue and the rostrum with blue or green, by the feeble depression on the wing-cases

behind the scutellum, and by the existence of some coarse sculpture on the sides of

the prothorax. The most remarkable of the differential characters are, however, the

peculiarities of the male of 4. lesicollis: the thorax in this sex bears two large depres-

sions; the head at the vertex has a transverse channel, connecting in front with a

longitudinal channel; the rostrum is comparatively very elongate; the head at the

sides behind the eyes is deeply excavate and beneath bears two slight angular promi-

nences; the middle of the breast of the prosternum bears also a slight prominence ;

and the apex of the rostrum bears two compressed or laminate tubercles directed

forwards, not downwards. The sexual structure of the front legs is the same as in

A. corvinus.

Our figure represents a male, and the accompanying outline (fig. 5 a) gives the pro-

portions of the head and rostrum of the same sex.

15. Attelabus 2

Hab. Mexico, Tierra Colorada in Guerrero (H. H. Smith).

A single female example. This is probably the exponent of a species very near to

A. lesicollis ; it is smaller, and has the eyes placed nearer to the thorax, but the male

should be known before a decision is made about it.

16. Attelabus callosus, sp.n. (Tab. I. fig. 6, ¢.)

Nigerrimus, nitidus ; elytrorum humeris elevatis et lateraliter compressis ; antennarum clava elongata.

Long. 6 millim, (rostr. excl.).

Hab. Mexico, Toxpam (Sad/é) ; Guaremaua, Purula, Coban (Champion); Nicaragua,

Chontales (Belt); Panama, Volcan de Chiriqui 2000 to 4000 feet (Champion).

Allied rather closely to A. corvinus, but readily recognized by the peculiarly shaped

shoulders of the elytra, and the longer club of the antenne; also with other minor, but

constant, distinguishing characters. ‘The thorax is polished, and possesses only a. very

scanty and quite obsolete punctuation. ‘The elytra are rather coarsely striate-punctate at

the base, but elsewhere are polished and nearly destitute of sculpture. ‘The club of the

antennz is elongate, its first joint in the male being nearly twice as long as broad. In

the male the thorax, head, rostrum, front legs, and antenne are longer than in the

female, the distance between the back of the eyes and the front of the thorax being

more than half the length of the thorax ; and the rostrum possesses at the apex beneath

two small laminiform projections extending forwards: in the female these projections

are wanting and the shorter front tibie are bimucronate at the apex.

Found freely on the Volcan de Chiriqui and at Purula; from Toxpam and Chontales

only single specimens have been received.

17. Attelabus conicollis, sp.n. (Tab. I. fig. 7, 2.)

Sanguineo-rufus, nitidus; prothorace squali, subconico, parce obsoleteque punctato; elytris subquadratis,

pone scutellum vix impressis, punctorum seriebus tantum ad basin conspicuis.

Long., ¢, 7 millim.

Hab. Mexico, San Andres Tuxtla (Sallé), Teapa in Tabasco (H. H. Smith); British

Honpuras, R. Hondo (Blancaneaua); GuateMALA, El Reposo (Champion), Panzos

(Conradt) ; Nicaracua, Chontales (Belt, Janson).

Head rather broadly but vaguely sulcate behind the eyes. Thorax with the usual

curved or angulate transverse sulcus very obsolete. Scutellum very broad. LElytra less

shining than the thorax, the punctures of the series very fine except at the base; the

depression behind the scutellum slight, and not extending so far outwards as the

scutellum itself. In the male the thorax, head, rostrum, and front legs are longer

than in the female, and the rostrum bears near the extremity beneath two projecting

acute tubercles ; the antenne are longer in the male, but the club is elongate in each of

the sexes, and scarcely shorter in the female.

Our figure is taken from a female found at Chontales.

18. Attelabus sedatus, sp. n.

Sanguineo-rufus, nitidus, nudus; prothorace transversim subconico, impunctato; elytris subquadratis, pone

scutellum vix impressis, ad basin seriatim punctatis, preterea fere impunctatis ; antennarum clava elon-

gata, laxe articulata.

Long. 8 millim.

Hab. Mexico, Toxpam, Tuxtla (Sal/é), Oaxaca, Paso del Macho (Hoge); GuaTEMALA,

Yzabal (Sad/é).

One of the smallest species of the genus, and one in which the sculpture of the upper

surface is the least distinct. Very closely allied to A. conicollis, but not half the size of

the smallest individuals I have seen of that species. The thorax is remarkably smooth

and even, there being, however, a slight depression or constriction across it behind the

front margin. ‘The series of punctures on the elytra are distinct only at the base and

near the scutellum. In the male the club of the antenne is slender and elongate, its

first and second joints being each longer than broad ; the rostrum is furnished with two

acute tubercles at the apex beneath; the head is not sulcate behind the eyes; and the

front tibize are slender and elongate, and armed with a single mucro at the apex. The

female differs in the shorter, bimucronate tibie, and the absence of the denticles on

the rostrum.

Eight examples.

19. Attelabus angulipennis, sp. n.

Brevis, testaceus ; oculis parum distantibus; prothorace conico-transverso, impunctato ; elytris ad latera pone

Long. 3 millim.

Hab. GUATEMALA (Champion).

ATTELABUS. 9

Eyes rather elongate, the space between them not broad, feebly sulcate. Thorax

with an obsolete transverse depression across it behind the front margin. Scutellum

rather narrow. Elytra with a prominent minute angle directed outwards just behind

the shoulder, not impressed behind the scutellum; at the base with distinct series of

punctures which become very fine and obsolete behind. |

We have received only one example of this obscure insect. It resembles A. sedatus,

but is distinguished by the angulated sides to the elytra. It was mounted by its captor

on the same card with a specimen of A. corallinus, to which it is also extremely similar,

though that species belongs to another group of the genus.

20. Attelabus brevicollis, sp. n.

2. Piceo-sanguineus, nudus, nitidus, antennis nigris; prothorace transverso, parce punctato, subinsequali;

elytris pone scutellum vix impressis, subtiliter seriatim punctatis, punctis basin versus minus subtilibus.

Long. 4 millim.

Hab. Mexico, Tapachula in Chiapas (Hoge); Guaremaa, El Reposo (Champion).

Although we have received only two females of this species there can be no doubt it

is distinct from A. conicollis and A. sedatus, owing to its shorter, less smooth thorax.

The head is bisulcate and rugose between the eyes; the thorax is shining, sparingly

punctate, broadly but vaguely transversely depressed behind the front margin, and

bears some small irregular depressions. In other respects A. brevicollis is very similar

to the corresponding sex of the two species named. The summit of the vertex is

rather deeply impressed, which leads to the supposition that the male may have a

peculiarly formed head as in A. lesicollis.

The localities for this species are both situate on the lower part of the Pacific slope,

and not very far distant from each other.

21. Attelabus melanopygus, sp. n.

2. Parvus, brevis, convexus, nitidus, rufus, capite cum rostro antennisque, pedibus, scutello pectoreque nigris,

femoribus basi rufa; prothorace transverso, levigato ; elytris ad basin seriatim punctatis, ad apicem

levigatis.

Long. cum rostro 3 millim.

Hab. Muxico, Amula in Guerrero 6000 feet (H. H. Smith).

Head short, the eyes very near to the thorax, rather widely separated, with a channel

along the inner margin of each, and a groove along the middle of the front part of the

space separating the channels; antenne short, with rather large club of three sub-

equal joints. ‘Thorax about twice as broad as long, rounded at the sides and narrowed

in front, smooth and shining. Scutellum moderate, a little broader than long. Elytra

short and broad, with series of distant punctures, which are distinct only at the base

and near the suture. Ventral segments and bases of the femora red, the pygidium black.

This species, of which only one female example has been obtained, is allied to the

North-American 4. analis, but by no means closely.

Long. 4 millim.

Hab. Panama, Bugaba 1000 feet (Champion).

Although we have only a single female example in a bad state of preservation, and it

is closely allied to both A. sedatus and A. brevicollis, there is no doubt it is quite distinct

from either. Itis at once distinguished from A. brevicollis by the eyes being separated

only by a smooth carina instead of a broad rugose space; from A. sedatus it may be

identified by the more approximate eyes, and by the shorter, more uneven, less smooth

thorax. The club of the antenna is remarkably elongate and slender, and on this account

the species is best placed near A. sedatus. The eyes are only very slightly convex; the

thorax is foveolate on each side of the middle, sparingly punctate ; the scutellum is very

broad ; and the elytra are very feebly depressed behind the scutellum, striate at the

base and towards the suture, elsewhere with series of very fine punctures.

The dark colour of the legs and antenne may possibly be due to decomposition,

but the black posterior part of the wing-cases is no doubt natural.

23. Attelabus ligulatus, sp. n.

Sanguineo-rufus, nudus, nitidus; oculis convexis ; prothorace transverso, inequali; elytris ad latera utrinque

Long. 47 millim.

Hab. Mexico, Playa Vicente (Sallé, Hoge), Cordova (Sallé); GuatemaLa, Coban

(Conradt); Panama, Bugaba (Champion).

In this species the male exhibits characters analogous to those of A. lesicollis, and

possesses a further remarkable peculiarity, inasmuch as the two tubercles of the under

surface of the rostrum are largely developed and amalgamated together, forming a

ligula divided at the extremity only, and projecting considerably beyond the mouth.

The head is deeply bisulcate between the prominent eyes, rugose in the female,

but little sculptured in the male; the vertex in the male is very elongate and

curvate, and is transversely and longitudinally impressed. The thorax is short,

sparingly and feebly punctured in the female, almost impunctate in the male; but in

this sex it bears two longitudinal impressions on the disc, and the oblique lateral

impressions are deeper than in the female. The elytra have an angular projection on

each side just behind the shoulders, and the inner strie are very deep at the base.

The scutellum is very broad and short. The club of the antenne is moderately long.

The front femora in the male are angulate beneath; in the female they are formed as

in the corresponding sex of the allied species.

Four examples. The only specimen found at Bugaba is a female. :

Long. 5 millim.

Hab. Nicaracua, Chontales (Janson).

Head elongate, the summit of the vertex canaliculate; eyes convex, widely sepa-

rated, the space between them bisulcate, the interval between the sulci broad, uneven.

Thorax almost impunctate, transversely impressed towards the front, and also with an

angulate transverse impression extending completely across it. Scutellum extremely

broad. FElytra with an obtuse elevation on each side behind the shoulder; near the

base and towards the suture with deep strie, which are continued backwards as series of

extremely fine punctures; behind the scutellum there is a slight depression.

Two females.

Allied by the form of the elytra to A. callosus ; but, besides differing much in size and

colour, the head is differently formed, the eyes in A. quadratus being prominent and

the grooves between them separated by a broad interval.

II. Anterior femora irregularly serrate ; form extremely short and broad.

Jekel considered a specimen from Mexico sent to him by Sallé as distinct; but 1 am

not able to find any satisfactory characters to distinguish individuals of our region from

examples found at Monte Video, these localities being apparently the extreme points of

its distribution ; the characters relied on by Jekel are but slight, and some of them are

not confirmed by the examples before me.

A, ater appears rare in our region, only five examples having come under my obser-

vation. We figure the example found in Guatemala by Mr. Champion.

Attelabus corallinus, Gyll. in Schénh. Gen. et Spec. Cure. v. p. 317°.

Hab. Mexico (Chevrolat!), Teapa (H. H. Smith, Sallé), Oaxaca, Chilpancingo (Hége),

Rio Papagaio (H. H. Smith); Guatemaua, Las Mercedes, Mirandilla, Panima, Senahu

(Champion).

Gyllenhal’s description was based on a male example; the female has two small

tubercles instead of one tooth on the front femur. The examples I refer to A. corallinus

show a good deal of variation, and there may be more than one species among them ;

but as we have only received one or two examples from each locality, I can form no

certain opinion on this point.

27. Attelabus bullatus, sp. n.

Sat elongatus, rufus ; prothorace, elytris, tibiis omnibus femoribusque quatuor posterioribus testaceis ; elytris ad

suturam rufo-signatis, ad basin utrinque bulla elongata elevata, fere impunctatis.

Long. 53 millim.

Hab. GuatEMALA, Sinanja in Vera Paz (Champion).

Rostrum short, punctate; eyes not very remote from the thorax, moderately promi-

nent, the space separating them rather broad, sulcate in the middle. ‘Thorax shining,

smooth, of a livid yellow colour above, with an angulate depression extending completely

across it and on each flank with an oblique impression. Scutellum large, triangular, with

the apex truncate. Elytra rather elongate, of a yellow colour, red along the suture,

and with an indistinct red transverse mark in front of the posterior declivity; at the

base on each side of the scutellum is an oval elevation, and between the elevations are

some obscure punctures, elsewhere impunctate. Legs yellow, with the front femora

red, except at the base, the middle and hind femora marked with red beneath.

Described from a single example of the male sex. The front femur has a rather long

tooth near the extremity, and a tubercle near the middle; the ventral segments are

deplanate and densely covered with pubescence.

28. Attelabus auratus, sp.n. (Tab. I. fig. 9, ¢.)

Antenne pale red, the club elongate. Rostrum short, the head moderately long, the

eyes convex, separated by a narrow space which is deeply sulcate above. Thorax rather

short; surface finely rugose, with an angulated impression extending across the middle;

on each flank deeply obliquely impressed. Elytra rather long, of a yellow colour (when

wetted this becomes golden, and is no doubt of that colour during life), margined with

dark red at the sides and suture, with a raised oval space at the base on each side of

the scutellum ; behind these elevations is a transverse band of dark red colour, which is

coarsely punctate, the parts behind being nearly smooth.

Also described from a single male example. The upper surface of the anterior femur

is shagreened; on the front edge towards the extremity there is a tooth, and near the

middle are two tubercles placed one above the other. The ventral segments are deplanate

on a rather small space, and pubescent, the pubescence at the sides being long and

erect.

B. Thorax with constriction behind the front margin.

29, Attelabus breviceps, sp.n. (Tab. I. fig. 10.)

Rufus; elytris sulcatis, plagis plurimis testaceis (in vita auratis), lateribus ad medium angulo elevato; capite

inter oculos sulcato ; pedibus testaceis, femoribus anterioribus ex parte majore rufis, in utroque sexu

bidentatis.

Long. 4 millim.

Hab. Panama, Bugaba 1000 feet (Champion).

Head and rostrum very short, the eyes short, very convex, separated by only a small

space, which is deeply sulcate. Thorax pale red, with a transverse depression behind

the front margin and a deep angulated impression across the middle, the angle of this

impression prolonged backwards as a short longitudinal impression, impunctate.

Elytra moderately long, with a small angular elevation on each side about the middle ;

rather deeply sulcate, the sulci at the base coarsely punctate ; of a dark red colour, with

a yellow space on each side of the scutellum, an elongate yellow mark behind the

shoulder, a large geminate one before the extremity, and between these and the base

four other marks placed transversely.

The sexual characters in this very distinct species are only slight, but in the male

the front tibize are a little longer and there is only one mucro at their extremity, in

the female there is a rather obscure second mucro.

feet (Champion).

Although so widely distributed in our region this is apparently not a common insect ;

14 RHYNCHOPHORA.

from many of the above localities we have received only one example, but Mr. Cham-

pion procured a fair series at San Gerdnimo. ‘The only important sexual distinctions

are to be found in the front legs: in the male the front femora are bidentate, the tooth

placed on the middle being long and slender, much longer than the other nearer the apex,

and the tibie are slender and possess a single mucro at the apex ; in the female the femora

are also bidentate, the tooth on the middle being, however, quite short, shorter than the

other, and the tibie are stouter and bimucronate at the apex. There is some variation in

size, the specimens from Panama and Nicaragua being smaller than most of the others ;

the peculiar spot on the wing-cases is also rather larger in some specimens, but the

difference in this respect is not great. We figure the female example from Nicaragua.

31. Attelabus fenestratus, sp.n. (Tab. I. fig. 12, 2.)

Rufus ; capite prothoraceque eneo-micantibus ; abdomine, pedibus quatuor posterioribus femoribus anterioribus

ad basin pallide flavis, tibiis tarsisque anterioribus rufo-testaceis ; elytris plagis duabus magnis, eburnaceis

ornatis.

Long. 4 millim.

Hab. Panama, Bugaba 1000 feet (Champion).

Closely allied to A. dinotatus, but easily distinguished by the colour-characters, and

the remarkably conspicuous ivory-like marks on the middle of the elytra; it is also a

shorter insect.

Described from a single female. The front femora are bidentate as in A. binotatus,

but the outer tooth is strongly sinuous externally.

82. Attelabus championi, sp. n.

Sat elongatus, rufus ; abdomine pedibusque quatuor posterioribus minus saturatis, femoribus anterioribus ad

basin flavis; elytris fortiter punctatis, guttis duabus testaceis, pellucidis, rotundatis ornatis.

Long. 5 millim.

Hab. Panama, Bugaba (Champion).

Of this species also we have received only one female: it is very similar to the more

elongate examples of A. binotatus, but is no doubt quite distinct; the antennal club is

elongate ; the front legs are dark sanguineous-red, the tibiae being concolorous with the

femora, and these last having the slender basal portion clear yellow. The thorax is

very polished and has a brassy tinge; the elytra are long and slender, their sculpture

very coarse and irregular, but much less deep than in A. binotatus ; the apical tooth

of the front femur is longer and more’slender than it is in A. binotatus.

33. Attelabus cruralis, sp.n. (Tab. I. fig. 13, 3.)

Elongatus, piceus; antennis pedibusque elongatis; elytris grosse punctatis, medio guttula testacea pellucida

ornatis.

Long. 7-8 millim.

Hab. Mexico, 'Toxpam (Sal/é); GuaTEMALA, Las Mercedes, Cerro Zunil, Purula

(Champion); Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion).

ATTELABUS. 15

Joints 3 to 7 of the antenne long ; head elongate ; eyes very distant from the thorax,

the space between them convex, bearing a short groove. Median groove of the thorax

moderately deep. Scutellum rather narrow, triangular, with the apex truncate.

Elytra with coarse impressions of irregular form, subseriately arranged, deeply sulcate

on the pre-apical declivity, each in front of the middle with a small, round, pellucid

yellow spot. Front legs very long: in the male the tooth on the middle of the front

femur is extremely elongate, and is curved; in the female there is in its place merely a

tubercle, but the apical tooth is longer than it is in the male.

Mr. Champion procured a series of twelve examples at Purula, and these exhibit

very little variation; we have only one or two representatives from each of the other

localities, and each of them differs more or less from the typical examples, so it is

probable there may be considerable local variation in the species. ‘The two specimens

from the State of Panama have the sculpture of the elytra much less deep, the pellucid

spots a little larger, and the middle groove of the thorax subobsolete.

34. Attelabus mundanus, sp. n.

Sat elongatus, rufo-piceus, nitidus; antennis pedibusque anterioribus elongatis ; elytris grosse irregulariterque

-punctatis.

Long. 64 millim.

Hab. Mexico, Cordova (Sallé); Panama, Bugaba (Champion).

Intermediate in some respects between A. binotatus and A. cruralis, but differing

from both by the complete absence of the pellucid spot on the wing-cases; the sculp-

ture of these parts is remarkably coarse, deep, and irregular. The armature of the

front legs in the two sexes differs but little from that of A. denotatus.

Three examples from Mexico, one from the State of Panama.

35. Attelabus inezequalis, sp.n. (Tab. I. fig. 14, 2.)

Elongatus, cneus, rugosus ; elytrorum lateribus utrinque spina grande ornatis ; femoribus ad basin flavis.

Long. 64 millim.

Hab. Mexico, Playa Vicente (Sad/é); Brrtish Honpuras, R. Hondo (Blancaneuz) ;

GuaTEMALA, Coban (Conradt); Nicaragua, Chontales (Janson).

Head elongate, rugose. Thorax with the anterior and posterior transverse grooves

definite, the middle ones more indefinite, the surface rugose. Scutellum subtriangular, its

apical portion convex, obscurely truncate. Elytra coarsely and irregularly sculptured,

brassy, shining; each about the middle of the length of the side furnished with a very

large spine directed outwards and very slightly upwards, and between this and the suture

is an angular elevation. Front legslonger in the male than in the female, the femora

bidentate in each sex; in the male the tooth on the middle is equal to that nearer the

apex, but in the female this tooth is represented by a tubercle.

Twelve examples. The figure is taken from a female example found at Chontales.

This species belongs to a group the representatives of which are chiefly Antillean.

Rhynchites, Herbst, Natursyst. Kif. vii. p. 123 (1797).

Lasiorhynchites, Jekel, Ins, Saund. i. p. 227, note."

This genus consists at present of about 100 species, distributed in the continental

regions of both the Old and New Worlds, but there are very few representatives

described from South America. The North-American species are moderately numerous,

but they are not yet very well elucidated.

We have obtained a fair series of species from our region which may be arranged in

three groups, besides an aberrant species which may form ultimately another genus.

Jekel, when describing a species of one of these groups, proposed for it the name of

Lasiorhynchites, stating, however, that the European Rhynchites pubescens was the type of

the group or subgenus. This association is, however, an unnatural one, as E. pubescens

cannot be placed in the same subgenus as ft. rufiventris, which is a member of a group

peculiar to the tropical regions of the New World. So far as the species of our region

are concerned Lasiorhynchites, Jekel, is therefore a synonym of Rhynchites.

Acaguizotla in Guerrero (H. H. Smith), Orizaba (2. D. G., H. H. Smith, Sallé), Puebla,

Cuernavaca, Guanajuato (Sallé).

This is apparently the least rare of the Mexican species of the genus, and a good series

was procured by Herr Hoge at Aguas Calientes, and by Dr. Palmer at San Luis Potosi,

but from each of the other localities we have only one or two examples. The species is

no doubt a variable one, and if all the examples I am considering be really referable to

one species, then it is a very variable one, and may probably not be distinct from the

North-American R. e@neus. Most of the examples may be described as belonging to a

large variety with slight striation of the elytra, and with great development of the

interstitial punctuation, the colour being usually green; specimens of a blue colour

with regular striation and serial punctuation on the interstices as described by Bohe-

man are rare, and seem to be quite connected by intermediate specimens with the

commoner form ; a black or blue-black variety occurs with still deeper striation; and

RHYNCHITES. 17

near the City of Mexico Hége obtained a single example of very small size (long. 4¢

millim. incl. rostr.) and approaching in punctuation the Guatemalan &. distans. It is

probable, however, that this latter variety may prove to be distinct. ‘The male of

R. mexicanus possesses a peculiar sexual character that has not hitherto been noticed :

on the posterior part of the suture of the elytra the erect hairs are more numerous, and

are so placed as to form two short divergent rows on each of the margins of the elytral

suture. In the males of the deeply striate varieties this character, however, does not

exist.

Aineus, densissime punctatus, griseo-hispidus.

Long. cum rostro 3 millim.

Hab. GuateMaLa, Cerro Zunil 5000 feet (Champion).

A very distinct little insect, allied to R. @neus, of which we have received only one

specimen that is doubtless of the male sex. Antenne inserted at the middle of the

rostrum, brassy-black, with short, very broad, and abrupt club. Rostrum about as long

as the thorax, very rugose ; head coarsely, extremely densely punctate. Thorax small,

scarcely so long as broad, very densely punctate. Elytra densely punctate, the serial

punctuation scarcely distinguishable from the dense interstitial punctuation. Legs

brassy-black.

8. Rhynchites distans, sp. n.

Hab. Guaremata, San Joaquin and San Gerénimo in Vera Paz (Champion).

Closely allied to &. eneus, but of much smaller size than the smallest varieties of

that species, and with the elytra very differently punctuated and setose. In form and

sculpture the head and rostrum are in each sex similar to those of the corresponding

sex of R. wneus. The thorax is small, rounded at the sides, sparingly punctate, with a

short, fine channel on the disc. Elytra with regular series of punctures, but with the

punctures very far from one another, and with the interstices also serially punctate, the

punctures being fine and even more distant than those of the series. Four specimens.

nearly as long as broad, sparingly punctate. LElytra with series of moderately distant,

not coarse punctures, and with the interstices sparingly and finely seriate-punctate.

The construction of the club of the antenne in the male is very peculiar: the ninth

joint is quite as long as broad, the tenth is rather longer, and oblique at its extremity,

while the terminal joint is small and placed on the oblique truncature, so that in

certain positions it has the appearance of being inserted on the posterior aspect of the

preceding joint (fig. 17 a). Four examples, three males and one female.

5. Rhynchites leticulus, sp. n.

Yiridi-auratus, nitidissimus, parcissime breviter hispidus, rostro, antennis pedibusque nigris; prothorace par-

Long. cum rostro circiter 5 millim.

Hab. Mexico, Chilpancingo and Acapulco in Guerrero (Hége).

Club of the antenne short, broad, very abrupt. Rostrum with a few coarse longitudinal

rugee. Head narrow, with an impression between the eyes, very sparingly punctate in

front, impunctate behind. Thorax narrow, about as long as broad, slightly rounded

at the sides, very sparingly punctate, with a fine abbreviated channel on the disc.

Scutellum narrow. Elytra with series of very large punctures, and with a few minute

punctures on the interstices. In the female the rostrum is slightly longer than the

head and thorax ; in the male it is a little shorter.

This brilliant little insect has a very small amount of sculpture on the thorax and

is very scantily setiferous on the wing-cases. We have received only three examples.

6. Rhynchites subauratus, sp. n.

Thorax small, slightly rounded at the sides, very coarsely punctate. Elytra clothed

with long, erect, not dense, hairs, and bearing regular series of coarse deep punctures,

aud with a scanty, rather coarse, punctuation on the interstices.

The two examples from Guanajuato and the single one from San Luis Potosi agree

well with each other; the single specimen from Saltillo is a female of large size, with

rather more scanty punctuation, but is, I expect, referable to the same species. The

individual found by Truqui may be distinct.

Long. cum rostro 4 millim.

Hab. Mexico, Oaxaca, Zacualtipan in Hidalgo (Hége).

Antenne short, with short, extremely broad club. Thorax small, subcylindrical,

very slightly curved at the sides, closely and coarsely punctate, the punctuation on the

disc less. Scutellum quite narrow. Elytra with regular series of closely placed coarse

punctures, the interstitial punctures few and obsolete. In the female the rostrum is about

as long as the head and thorax, the antenne are inserted a little behind the middle of

the rostrum, and the rostrum is not so coarsely rugose in front. In the male the

rostrum is considerably shorter, the antenne are inserted just in the middle, and the

eyes are larger, so that the head is broader. Seven specimens.

A distinct species, easily recognized; the erect pubescence appears in certain lights

quite white.

8. Rhynchites scutellaris, sp. n.

Nigerrimus, nitidus, nigro-hirtus, scutello albido-piloso, corpore subtus griseo-pubescens ; capite prothoraceque

Var.(?) Major, elytris fortiter punctatis, interstitiis haud omnino planis.

Hab. Mexico, Juquila ({ége).

This species is closely allied to R. mollis, but on the upper surface the pubescence

does not appear white, except that the scutellum is more densely clothed with long

white hairs parted along the middle ; the punctuation of the head and thorax is much

scantier; on the elytra the serial punctures become quite fine on the posterior half—

they consist of a large puncture alternating with a very fine puncture—and the broad,

quite flat interstices bear also a few fine setigerous punctures. The rostrum is coarsely

sculptured ; the space between the eyes is impunctate, except laterally; and the vertex,

like the slender thorax, is moderately finely, not closely punctate. Four specimens.

The example from Juquila that I have treated as a variety will, I think, prove to be

distinct.

9. Rhynchites basalis, sp. n.

and the peculiar punctuation of the wing-cases, the punctures on the basal portion

of the latter being very large, while nearer the apex they are as minute as the inter-

stitial punctures. ‘The head and thorax are only sparingly punctate, and the pallid

pubescence on the scutellum is not conspicuous. On the under surface the elongate

pubescence is partly white. Two examples.

Hab. GUATEMALA, Duefias (Champion).

Rostrum rugose, not so long as the head and thorax. Antenne short, with broad, rather

long club. Head rather broad, with only a few distant, extremely fine punctures, very

shining. Thorax slender, cylindrical, longer than broad, remotely, very finely punctate.

Elytra broad and short, with the punctuation very fine and remote, but consisting

nevertheless of a serial punctuation, and of a serial interstitial punctuation still finer

and more remote. Five specimens. I observe no distinction that I can consider

sexual.

Hab. Guatemata, Chiacam, Tamahu, San Juan, San Gerdénimo (Champion).

Rostrum dull, entirely black; head also quite dull, nearly black, being very slightly

tinted with bluish colour, with a few very obsolete punctures between the widely

separated eyes. ‘Thorax elongate and narrow, longer than broad, but little rounded at

the sides, moderately closely, coarsely, and deeply punctate. Elytra with regular series

of punctures, the punctures rather coarse at the base, subobsolete towards the apex, but

again rather coarser and deeper on the declivous apex. |

We have only either one or two specimens from each locality, but I believe I have

the sexes before me; the rostrum and thorax being rather longer in one, which I

presume is the female. |

15. Rhynchites debilis, sp. n.

Niger, supra sneus, nitidus, omnino parcissime pubescens; prothorace elongato, sat crebre et sat fortiter

Long. cum rostro 23 millim.

Hab. Mexico, Jalapa (Hoge), Teapa in Tabasco (H. H. Smith).

This insect is very closely allied to R. guatemalenus, though the brassy colour is very

22 RHYNCHOPHORA.

different from the dull blue colour of that species, and the punctuation of the thorax is

rather more scanty. There is but little difference in the punctuation of the elytra; the

legs are brassy-black in colour.

16. Rhynchites pusillus, sp. n. (Tab. I. fig. 18.)

Niger, supra subcyaneus, tenuiter pubescens, sat nitidus ; prothorace dense fortiterque punctato, elongato; elytris

seriatim sat fortiter punctatis, interstitiis minus angustis.

Long. cum rostro 23 millim.

Hab. Panama, Bugaba (Champion).

This species is in sculpture rather similar to 2. confertus, but differs in its dark blue-

black colour and in the longer and more slender thorax. At first sight it is still more

like the European &. nanus, but the thorax is longer and narrower and much more

densely punctate. From R. guatemalenus the species is chiefly distinguished by the

very dense punctuation of the thorax, and by the less obsolete punctuation of the

elytra. ‘Two examples.

17. Rhynchites thesaurus, sp. n.

Auratus, nitidus, tenuissime pubescens ; rostro, antennis, pedibus, pectore abdomineque nigro-subeeneis ; protho-

race elongato, crebrius fortiter profundeque punctato; elytris seriatim fortiter punctatis, interstitiis latis,

haud omnino planis.

Long. cum rostro vix 24 millim.

Hab. Mexico, Teapa in Tabasco (ff. H. Smith).

This insect is very closely allied to &. debilis, but it does not agree in colour or

punctuation with it or with any other species of the group; and, besides this, it has

the vertex less sparingly and obsoletely punctate. The punctuation of the elytra on

the disc is not obsolete. The only two examples received have a short rostrum; yet !

fancy they are of opposite sexes, as there are some slight differences in the form and

punctuation of the thorax, as well as a small distinction in the length of the front part

of the rostrum.

18. Rhynchites chiriquensis, sp. n.

Late cyanens, nitidiusculus, pedibus eneis, rostro anterius antennisque nigricantibus ; parce obsoleteque punc-

tatus, fere levigatus.

Long. cum rostro 24 millim.

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

Of this distinct and beautiful little insect we have received only one example,

probably a female. It differs from all the other allied species by the diminished

sculpture, more polished surface, and beautiful colour. The rostrum is long and

slender, about equal in length to the head and thorax; shining black in front, behind

the antenne enescent, the vertex cyaneous. Antenne small, slightly brassy. Thorax

RHYNCHITES. 23

elongate and slender, slightly rounded at the sides, very remotely and not coarsely

punctured. LElytra with series of distant fine punctures, which, however, are rather

more distinct at the base.

§ 3. Pygidium covered ; rostrum strongly curved; head and thorax dissimilar in form

on the two sexes; punctuation of the elytra minute and remote ; size moderate.

19. Rhynchites rufiventris.

Rhynchites rufiventris, Jekel, Ins. Saund. ii. p. 226°.

Hab. Muxico', Toxpam, San Andres Tuxtla (Sadlé), Playa Vicente, Oaxaca (Hége),

Atoyac in Vera Cruz (H. H. Smith); Guatemata, Coban (Conradt).

This is apparently not a common insect, as we have received only thirteen examples of

it. It varies a little in colour, punctuation, and size, but I cannot distinguish more

than one species. ‘The peculiar colour of the ventral segments is probably a constant

character.

20. Rhynchites flaviventris, sp. n.

Nigerrimus, nitidus, abdomine flavo, setis erectis nigris minus dense vestitus, corpore subtus griseo-pubescente ;

sutura elytrorum ante medium fascicula acuminata pubescentiz albide.

Long. corp, absque rostro 5-54 millim. ; long. rostri 2 millim.

Hab. Mexico, El] Mirador (Sal/é).

Rostrum elongate, curvate. Head rather closely punctured. Thorax rather closely

punctate. Scutellum with a scanty white pubescence. LElytra shining black, with

numerous very distinct punctures, subserial in their arrangement, a small patch of

white hairs on the suture, and a few white hairs at the sides near the shoulders.

Under surface with a feeble white pubescence. In the male the rostrum is more

densely sculptured than it is in the female, the head is narrower, and the thorax is

more rounded at the sides.

This is the only one of our species, besides &. rufiventris, that has the ventral seg-

ments rufescent; and R. flaviventris is readily distinguished by the black colour, by

the greater punctuation of the upper surface, by the white hairs on the suture being

limited to a small space, and by the feeble white pubescence of the lower surface, the

lateral band of white pubescence being absent. One pair.

21. Rhynchites championi, sp. n.

Niger, nitidus, elytris violaceis ; parce punctatus, nigro-setosus, scutello elytrorumque sutura in parte basali,

elytris apicem versus, pectorisque lateribus albido-pubescentibus.

pion).

24 RHYNCHOPHORA.

Var. Niger, vix violaceo-tinctus, elytris parcius punctatis.

Hab. Guatemaua, Senahu (Champion).

This species is similar to R. rufiventris, but the ventral segments are quite black, and

the thorax is a little more slender. The punctuation is much the same in the two

species, and there is but little difference in their sexual distinctions. I include a

pair nearly black in colour as a variety, though it may probably prove distinct.

Like R. rufiventris, this insect does not appear to be common, but I have seen eleven

specimens from the various localities.

22. Rhynchites centralis, sp.n. (Tab. I. fig. 19.)

Violaceo-niger, nitidus, elytris violaceis ; crebre punctatus, nigro-setosus, scutello elytrorumque sutura in parte

basali, pectorisque lateribus albido-pubescentibus.

Long. cum rostro 7 millim.

Hab. Guatemaua, Capetillo (Champion), Aceytuno 5100 feet (Salvin).

We have only two examples (of the male sex) of this species; though very similar

to R. championi it may be easily enough distinguished by the less scanty punctuation.

‘he vertex is densely punctured, and the thorax is finely and rather closely punctured ;

the elytra have avery distinct evenly distributed punctuation, which, though not dense,

is more numerous and distinct than it is in Lt. championt, and the white pubescence at

the apex is conspicuous, as also is the white hair on the under surface.

23. Rhynchites mixtus, sp. n.

Nigro-violaceus, nitidus, crebre punctatus, griseo-setosus, corpore subtus griseo-pubescente, pectore ad latera

minus argute albido-cincto ; scutello elytrorumque sutura albido-pubescentibus.

Long. cum rostro 8 millim.

Hab. Mexico, Juquila (Sallé, Hoge).

We have only two females of this species; it appears to be nearest to R. centralis,

but has the white hair on the upper surface much more largely developed. The sete

consist to a great extent of upright white hairs, and the white pubescence on the

suture, instead of being condensed on the basal part, is evenly distributed along the

whole length ; the white pubescence of the under surface is similarly diffuse.

24. Rhynchites inermis, sp. n.

Nigro-violaceus, nitidus, minus dense hirsutus, parcius obsoletiusque punctulatus, scutello elytrorumque sutura

in parte basali, elytris apicem versus, pectorisque lateribus albido-pubescentibus.

RHYNCHITES. 25

Var.? Major, vix violaceo-tinctus, prothorace ad latera parcius punctato.

Long. cum rostro 84 millim.

Hab. Panama, Bugaba (Champion).

I should have treated this as only a variety of R. championi, but it has a more

slender thorax, and this part is but little dilated in the male; it differs, moreover, in

various other slight particulars from that insect. The punctuation of the thorax is

very fine, but is numerous at the sides. The elytra are flat, and become a good deal

broader behind, very little punctate, and the white pubescence on the suture and

scutellum is neither dense nor conspicuous; on the other hand, the white fascia on the

side of the breast is remarkably distinct.

We have received seven examples. The variety (?) from Bugaba very likely belongs

to a different species.

§ 4. Aberrant species, with rugose sculpture and elongate club to the antenne.

25. Rhynchites addendus, sp. n. (Tab. I. fig. 20.)

Parvus, angustus, subtus viridi-niger ; supra seneus, antennis pedibusque sordide testaceis ; capite prothoraceque

dense rugoso-punctatis; elytris omnino fortissime denseque rugoso-punctatis.

Long. cum rostro 34 millim.

Hab. Mexico, Jalapa, Oaxaca (Hége).

Rostrum longer than the head, shorter than the head and thorax, punctate-rugose ; head

elongate ; the eyes not large, very distant from the thorax, the surface between them very

densely and deeply punctate. Antenne inserted at the middle of the rostrum, obscure

yellow, with the terminal joint darker, the club elongate, each of its joints being con-

siderably longer than broad ; ninth and tenth joints equal in length, the terminal joint a

little shorter. Thorax slender, cylindric, slightly longer than broad, excessively densely

deeply punctate. Elytra with a very deep irregular sculpture, at the base in the form

of serial punctures, but beyond consisting of deep grooves, interrupted here and there

in an irregular manner, the interstices narrow. Legs slender.

We have received only two specimens of this peculiar little species, and they are in

a very mutilated condition. So far as I can see the characters, they do not fit well

into any established genus; the pygidium is exposed; the prosternum seems to be

formed as in Hugnamptus, except that I think the apices of the epimera are contiguous

and conjoined; the form of the head is very different from that of Hugnamptus; and

the basal joint of the hind tarsus is about as long as the following two joints together.

26 RHYNCHOPHORA.

RHYNCHITOBIUS, gen. nov.

Caput elongatum. Prosterni epimera in medio a parte centro-sternali minute separata. Coxe intermedis

latius distantes. Pectus prominulum. Pygidium obtectum. Unguiculi longius appendiculati.

The wide separation of the middle coxz allows this genus to be identified at a glance.

The rostrum is thick and elongate; the prosternum excessively short, the front coxe

very elongate. Each elytron is much rounded at the inner apical angle, and in conse-

quence of this a small part of the middle of the apex of the pygidium can be seen

between them.

1. Rhynchitobius longicollis, sp. n. (Tab. I. fig. 21.)

Piceus, subvariegatus, pube depressa grisescente irregulariter dense vestitus ; antennis rufis ; pedibus lanuginosis,

tibiis ex parte majore flavescentibus.

Long. cum rostro 5 millim.

Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion).

Antenne with broad club, the terminal joint quite acuminate. Rostrum thick,

straight, finely punctulate in front of the insertion of the antenne. Eyes widely sepa-

rated, the space between them rather convex, hairy. ‘Thorax slender, very elongate,

densely clothed with a pale griseous pubescence, and also bearing a few slender erect

sete. Elytra also clothed with pale depressed pubescence, which conceals the colour

and sculpture, the former probably somewhat variegate, the humeral part being, at any

rate, considerably paler, the sculpture apparently coarse and serial but irregular. ‘Tarsi

very thick.

Of this remarkable insect we have received only three examples, all in a very fragile

condition. They apparently represent the two sexes, one having the rostrum rather

longer than the others. I think this individual may be a male; our figure is taken

from it.

HEMILYPUS, gen. nov.

Caput post oculos haud constrictum ; rostrum breve, crassum. Antenne graciles. Tarsi articulo basali sequente

duplo longiore. Prosternum post coxas minus abbreviatum, epimerorum apicibus haud conjunctis.

Abdomen sutura prima ventrali profunda.

This genus resembles the eastern Aderorhinus in appearance; the prosternum behind

exhibits a triangular piece, the apex of which separates more or less widely the apices

of the epimera. It differs from Hugnamptus by the head being elongate and less con-

stricted ; the prosternum longer behind the coxe; the first ventral suture deep; the

basal joint of the feet shorter; and the pygidium not so completely covered. It should

be placed between Aderorhinus and Eugnamptus.

HEMILYPUS. 27

1. Hemilypus latipes, sp. n. (Tab. I. fig. 22.)

Niger, nitidus, parce pilosus; antennis fusco-testaceis, clava nigro-fusca; prothorace sat angustato, crebrius

punctato ; elytris regulariter seriatim punctatis.

Long. cum rostro 7 millim.

Hab. Mexico, Tuxtla (Sallé), Juquila (Hége).

Rostrum short, about as long as the head, the latter between the eyes, also the vertex,

sparingly punctate. Antenne very slender, infuscate yellow, with the slender club

darker, the terminal joint not quite so long as the tenth. Thorax narrow, rather longer

than broad, moderately coarsely and closely punctate, shining. Elytra with regular

series of distant punctures, which on the declivous apex are very fine, and with a few

excessively fine punctures on the interstices; the upright setosity is very conspicuous but

scanty. Legs broad, very hairy. Under surface feebly cyaneous; femora with white

hairs; sides of the breast clothed with some white hair.

I do not see any striking sexual distinctions among the three individuals we have

received. One specimen has the thorax a little broader and the eyes slightly smaller,

and may be a female.

2. Hemilypus sallzi, sp. n.

Nigerrimus, nitidus, parce pilosus; antennis fusco-testaceis, clava nigro-fusca ; prothorace angustiore, anterius

leviter angustato, parce punctato; elytris regulariter seriatim punctatis, punctis subtilioribus, tantum ad

basin sat magnis.

Long. cum rostro 6 millim.

Hab. Mexico, Toxpam (Sal/é).

Very closely allied to H. latipes, but differing as follows:—The size is smaller, the

thorax is narrower and more sparingly punctate, and the vertex and the head between

the eyes are also sparingly punctate; the punctures in the series of the elytra are finer,

and the pallid pubescence of the under surface is less. Three specimens, in bad

preservation.

3. Hemilypus hondurensis, sp. n.

Nigerrimus, nitidus, parce pilosus, antennis medio fusco-testaceis; prothorace conico-cylindrico, parcius

obsolete punctato ; elytris seriatim subtiliter punctatis.

Long. cum rostro 43 millim.

Hab. British Honpuras, R. Hondo (Blancaneauz).

This insect is very similar to H. latipes and to H. sallei, except that it is much

smaller and has more slender legs. The rostrum is quite short, not so long as the head ;

the terminal joint of the antenne is not so long as the tenth joint. The eyes are large,

and in front are strongly convergent, the space between them sparingly and finely punc-

tate. The thorax is long and narrow, a good deal narrowed in front; its punctuation

is obsolete. The serial punctures of the elytra are very fine, but more distinct at the

base. The griseous hair on the femora is not conspicuous.

The specimen described is no doubt a male, the middle tibia being incurvate at the

apex; the first ventral suture is quite deep. A very immature example found by

Conradt at Coban in Guatemala may perhaps be referable to this species.

4. Hemilypus obliteratus, sp. n. (Tab. I. fig. 23, var.)

Niger, nitidus, capite cyanescente, antennis fusco-rufis; supra parcissime setosus, pedibus corporeque ad

margines albido-pilosis ; elytris subtilissime remoteque scriatim punctatis.

Long. cum rostro 43 millim.

Hab. Panama, Bugaba (Champion).

Var.? an mas? antennarum clava valde elongata, articulo ultimo elongato.

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

Antenne rather long, obscure red, the terminal joint slightly longer than the tenth.

Rostrum broad, very short, not longer than the head; eyes not very large, the space be-

tween them, also the vertex, finely punctate. Thorax longer than broad, a little rounded

at the sides, sparingly punctate. Scutellum small, with white pubescence. Elytra with

very obliterated series of punctures; the punctures are quite fine, even at the base, and

at the apex can scarcely be detected. The white pubescence on the legs is very

conspicuous.

Two examples: in one the blue colour of the head is not very distinct. I suspect

the specimen with long antenne may be a male of another species, but it may be only

a variety ; it is in beautiful condition, and we figure it.

5. Hemilypus ——?

Hab. Guatemaa, Cerro Zunil 4000 feet (Champion).

A species closely allied to H. obliteratus, but evidently distinct, is represented by a

single example that is too immature for description.

ESSODIUS, gen. nov.

Rootrum elongatum, tenue, curvatum. Caput post oculos haud constrictum. Prosternum epimerorum apicibus

haud conjunctis. Abdomen sutura prima ventrali obsoleta.

This genus is established for an anomalous Rhynchitid, agreeing with Lugnamptus

in the prosternal structure, but differing greatly therefrom in the form of the rostrum

and head, and possessing a much shorter basal joint on the feet. So that if Hssodius

be not separated, I do not see how Eugnamptus could be defined.

ESSODIUS.—EUGNAMPTUS. 29

1. Essodius unicolor, sp. n. (Tab. I. fig. 24.)

Fulvus, prothorace leviter inaurato, parce pilosus, crebre punctato ; elytris seriatim subtiliter punctatis, inter-

stitiis parce subtilissime seriatim punctatis.

Long. cum rostro 5 millim..

Hab. Mexico, Zacualtipan in Hidalgo (Hége).

Rostrum rather longer than the head and thorax, slender, almost without sculpture,

the antenne inserted near, but not at, the base, elongate, with slender club, consisting of

three joints of about equal length, and each quite twice as long as broad ; eyes widely

separated, rather small but very prominent, the space between them finely punctate.

Thorax narrow, but not cylindric, a little rounded at the sides, moderately closely and

deeply punctate. Scutellum very small. Elytra with very regular serial punctuation,

which becomes quite obsolete at the apex, the serial interstitial punctuation very fine,

except that at the base there are a few larger punctures interposed between the first

and second series; the erect pilosity is rather scanty and of the same colour as the

surface. The legs are slender, the basal joint of the hind foot about as long as the

second and third joints together.

We have received seven examples of this species. I do not detect any sexual

distinctions.

EUGNAMPTUS.

Eugnamptus, Schonherr, Gen. Cure. v. p. 339 (1839); Sharp, Trans. Ent. Soc. Lond. 1889,

p. 69.

This genus has comprised hitherto some half-dozen North-American species, and

three or four others from Eastern Asia. It is evidently destined to prove very nume-

rous in species from tropical America, and it is doubtful whether the Old-World forms

will be retained in the genus. The species are very difficult to describe and some

exhibit much variation in colour, this being sometimes in part sexual. ‘The prosternal

structure is somewhat variable, but the apices of the epimera are always free ; though

I think I have observed in one species that one minutely overlaps the other, the apices

in this case not being united but separated by a small space. . A readily observed

character for the recognition of the genus exists in the extremely peculiar club of the

antenne, which is always very long and fragile, but varies much in the form and

proportion of the joints.

In addition to the series of species here described, I have evidence of the existence

of eight or ten other species in our region, each of which is represented by a single

example in too decayed condition for examination.

30 RHYNCHOPHORA.

§1. Pubescence of the body elongate and erect.

1. Kugnamptus validus, sp. n. (Tab. I. fig. 25.)

Fulvo-rufus, flavo-setosus ; rostro, antennis, tibiis tarsisque nigris.

Long. cum rostro 74 millim.

Hab, GUATEMALA, Sinanja in Vera Paz (Champion).

Rostrum elongate, longer than the thorax, shining black. Antenne biack, inserted

at one third of the length in front of the eyes; the club very long, the terminal joint

much shorter than the tenth, acuminate, three or four times as long as broad. Head

sparingly and finely punctate. Thorax rather longer than broad, rather finely and

sparingly punctate, the punctures extremely shallow. LElytra with regular series of

punctures which are fine and as large at the apex as at the base, the interstices very

broad, and with an excessively fine serial punctuation. The upright setosity is serial

in arrangement, and is slightly paler than the colour of the surface.

Of this distinct species we have received only one specimen; it is rather immature,

and will not bear much manipulation, but from its size and proportions I judge it will

come near to the genus Rhynchites.

2. Kugnamptus divisus, sp.n. (Tab. II. fig. 1.)

Fulvo-rufus, flavo-setosus; antennis pedibusque nigris, femoribus basi rufa.

Long. cum rostro 5 millim.

Hab. Guatemata, Panajachel 5000 feet, Cerro Zunil 4000 feet (Champion) ; Panama,

David (Champion).

Rostrum very short, only as long as the head (in the male). Antenne black, slender

and elongate, with very long, linear club, the terminal joint of which is much shorter

than the tenth. Head sparingly punctate. Thorax sparingly punctate, slender, longer

than broad. Elytra with regular series of definite, rather remote punctures, and

with a fine, serial interstitial punctuation. Legs black, with the base of the femora

pallid red.

We have received three examples of this species; the apex of the middle tibia is

strongly incurved in the male, in the female the rostrum is rather longer. This insect

is very similar in its proportions to Hemilypus obliteratus, but the much longer basal

joint to the hind feet and the obliterated first ventral suture of Hugnamptus divisus are

sufficient for generic distinction. The figure is taken from the female found in the

State of Panama.

3. Eugnamptus diabroticus, sp. n. (Tab. II. fig. 2, 3.)

Rostrum slender, in the male quite as long as the thorax, in the female a good deal

longer. Antenne very long, the club very long and slender, the terminal joint but little

shorter than the tenth. Head finely punctate. Thorax rather finely punctate. Elytra

with regular series of punctures, obliterated at the apex, the interstices very broad,

their remote serial punctuation very obsolete; there is a black basal fascia interrupted

at the suture, and a second fascia just in front of the middle, interrupted at the suture

and each half more or less distinctly divided into two spots; the erect setosity is not

very long. The legs are yellow with black tibize, and the basal joint of the tarsus more

or less deeply black.

We have received three examples of this remarkable species; we figure the male

from Cerro Zunil, which has the rostrum shorter, the eyes larger, and the apex of the

middle tibia a little more prolonged inwardly.

4, Kugnamptus maculatus, sp.n. (Tab. II. fig. 3.)

Rufus, parce setosus; antennis, pedibus elytrorumque maculis quatuor nigris, femoribus omnibus ex parte

Long. cum rostro 4-43 millim.

Hab. Mexico, Oaxaca (Hége), Atoyac and Fortin in Vera Cruz, Teapa in Tabasco

(H. H. Smith).

Rostrum very short, broad; head nearly impunctate, the eyes very large, the vertex

short. Antenne very long, quite black, the terminal joint only half as broad as the

tenth. Thorax slender, longer than broad, obsoletely and sparingly punctate. Llytra

with quite regular series of distant punctures, obsolete at the apex. ‘The tibize and tarsi

in larger part and the apices of the femora black. Male with the extremity of the

middle tibia incurved at the apex. |

We have received seven examples of this species, and apparently all are males. The

blaek spots vary greatly in size, and possibly they may be sometimes entirely absent ;

but, independently of the black spots, the species is easily recognizable by the dimi-

nished punctuation of the head and thorax.

5. Hugnamptus basalis, sp. n.

Rostrum very short, scarcely so long as the head; the latter almost impunctate.

Thorax slender, very coarsely punctate. Elytra with an oblong black spot on each side

of the scutellum; with regular series of coarse punctures, finer on the apex, and with

a remote serial punctuation on the interstices.

The five examples received of this species are in a very fragmentary state, and the

terminal joint of the antenna is not present in any of them; but the club is evidently

of excessive length, the tenth joint being nearly as long as the rostrum. ‘The speci-

mens are, I think, all of the male sex.

6. Eugnamptus latirostris, sp. n.

Testaceus, setosus; capite, prothorace femoribusque pallide rufis, antennis, tibiis, tarsis elytrorumque fascia

basali, et maculis duabus transversis in medio, nigris ; elytris seriatim sat fortiter punctatis.

Hab. GuateMata, San Gerénimo (Champion).

2. Rostrum broad, moderately long, greatly dilated at the extremity. Antenne

extremely long, inserted just behind the middle of the rostrum; head almost impunc-

tate. Thorax small, not longer than broad, moderately closely punctate. Elytra with

very regular series of distant, moderately large punctures, finer at the apex, the inter-

stitial punctuation scarcely visible.

The only example received is in very decayed and discoloured condition ; the male

has probably a shorter and more slender rostrum.

7. Eugnamptus godmani, sp. n. (Tab. II. fig. 4.)

Testaceus, setosus, dense punctatus; capite, prothorace antennisque fuscis, his apicem versus testaceis ; elytris

ex parte majore nigris, fascia postbasali apiceque testaceis.

Long. cum rostro 54 millim.

Hab. Payama, Volcan de Chiriqui 4000 to 6000 feet (Champion).

¢. Antenne elongate, the club very slender, the terminal joint more than half as long as

the tenth. Rostrum rather longer than the head, the latter closely and finely punctate.

Thorax rather longer than broad, coarsely, densely, and deeply punctate, with a short

deep channel on the disc. Elytra with a basal uninterrupted fascia black, and a second

fascia, extremely large and slightly interrupted at the suture, of the same colour; they

bear very regular series of coarse closely placed punctures, and have a distinct inter-

stitial punctuation, the interstices being rather narrow and somewhat elevated.

The only example received is in a somewhat discoloured condition from decay.

The species is very distinct owing to the very coarse thoracic punctuation; the elonga-

tion of the antenne is due not only to the club, but to the joints preceding it being

also elongate.

8. Kugnamptus sexmaculatus, sp. n.

Rufo-testaceus, elytris testaceis, nigro sexmaculatis ; antennis fuscis, clava elongata, articulo ultimo pallidiore.

Eyes very large, not distant from the thorax, the space between them almost im-

punctate. Thorax coarsely punctate, with a short channel on the disc. Elytra with

very regular series of large, closely-placed punctures, the interstices rather narrow, sub-

convex, seriately, finely punctate ; each with three black marks, one at the base, one on

the middle, and one just before the apex.

Three specimens; all females, having the rostrum a good deal dilated at the apex.

9. Kugnamptus seriatus, sp. n.

Parvus, testaceus, setosus, elytris ad basin et ultra medium nigro-signatis; antennis fuscis, articulo ultimo

flavo ; elytris seriatim punctatis, interstitiis subconvexis, minus latis.

Long. cum rostro 37 millim.

Hab. Mexico, Teapa in Tabasco (ZH. H. Smith).

Rostrum very short, not so long as the head, the latter short, with extremely large

eyes. Antenne moderately long, the terminal joint yellow, much shorter than the

tenth. Thorax very slender, sparingly and coarsely but very lightly punctate. Elytra

with a black mark at the base close to the scutellum, and a lateral mark on the outer

margin, these two connected by a slender black line along the extreme base; there

is also a small black spot just behind the middle of each; the serial punctures are

very regular, deep, and rather closely placed.

One specimen; probably of the male sex.

10. Hugnamptus dispar, sp. n.

Rufo-testaceus, breviter setosus, prothoracis elytrorumque lateribus plus minusve late nigro-signatis ; capite

parce subtilissime punctato ; prothorace dense fortiterque punctato; elytris seriatim profunde punctatis,

interstitiis subconvexis.

Long. cum rostro 5 millim.

Hab. Guatemata, Mirandilla 1700 feet (Champion); Panama, Volcan de Chiriqui

2500 to 3000 feet (Champion).

g. Antenne moderately long, the terminal joint about as longasthe tenth. Rostrum

- short and broad, much dilated at the apex; eyes large, rather widely separated, the space

between them shining, very sparingly punctate. Thorax rather short, slightly longer

than broad, a little rounded at the sides, very coarsely punctate. Elytra with series of

deep, rather closely placed punctures, the interstices rather narrow, very indistinctly

punctate; the colour is yellow, but very broadly black at the base and sides, and with

the rudiments of an obsolete black fascia across the middle.

Three examples agree closely; a fourth though considerably different is, I have no

doubt, the male. Its form is more slender, the antenne more elongate, the eyes very

large and approximate, the thorax more slender, and the black marks on it and on the

wing-cases only faintly indicated.

11. Eugnamptus cinctus, sp.n. (Tab. II. figg. 5,3; 6, 2.)

Rufo-testaceus, setosus, antennis fuscis, clava nigra, elytris ad latera nigro-viridi cinctis ; prothorace crebrius

fortiter punctato.

Long. cum rostro 53-6 millim.

Hab. Mexico, Zacualtipan in Hidalgo (£/dge).

Var. elytris nigro-viridis, circa scutellum vage rufescentibus.

Antenne with only moderately long club, the terminal joint slightly shorter than the

tenth. Rostrum short, the head very finely punctate. Thorax coarsely and closely

punctate. Elytra with regular series of rather fine and distant punctures, the inter-

stices broad, flat, and with only an extremely fine, remote punctuation.

We have received a good series of this species; the colour of the elytra is variable

owing to the lateral cincture being developed to a greater or less extent, and sometimes

nearly covering the surface ; the sexual disparity is very great, the male being a rather

longer, more fragile insect, with much larger and more approximate eyes, and slightly

shorter rostrum. |

12. Kugnamptus longipes, sp. n.

Longulus, testaceus, setosus, antennis valde elongatis, nigricantibus, basi fusco-testacea ; prothorace sat crebre

et fortiter punctato ; elytris seriatim sat fortiter punctatis, interstitiis subtiliter seriatim punctatis.

Long. 5-6 millim.

Hab. GuateMata, Capetillo, Calderas (Champion).

Var. elytris ex parte majore nigro-viridi-tinctis.

This insect is very closely allied to E. cinctus, but is more elongate, has a consider-

ably longer club to the antenne, and the lateral cincture of dark colour on the wing-

cases is absent. The variety suffused with green is usually, if not always, of the female

sex, and differs from the corresponding variety of H. cinctus in having the lateral margins

of the elytra pale, the dark colour extending forwards from the apex. The distinctions

of the sexes are much the same as in #. cinctus, with the exception that in the female

of E. longipes the eyes are larger and less widely separated than they are in the corre-

sponding sex of &. cinctus.

Twelve examples have been received. A very mutilated specimen found in Mexico

by Truqui may possibly be referable to this species.

13. Hugnamptus tibialis, sp. n.

Longulus, testaceus, breviter sctosus, minus nitidus, antennis valde elongatis; vertice prothoraceque densius

punctatis; elytris seriatim profunde punctatis, interstitiis minus latis, convexis.

Long. cum rostro 5 millim.

Hab. Mexico, Oaxaca (fHége).

g¢. Antenne very elongate, the club long and slender, unicolorous, the terminal joint

EUGNAMPTUS. 35

quite as long as the tenth. Eyes very large, the surface of the vertex closely and

finely punctate. Thorax rounded at the sides, coarsely and very densely punctate, with

a short channel on the disc. Elytra with series of closely placed punctures; the acces-

sory punctures near the scutellum forming a very definite, short series. Middle tibia

rather broad, its outer edge densely ciliate with dark, short hair, the inner angle much

produced.

Although similar to E. cinctus and E. longipes, this species is very distinct owing to

its sculpture. We have received only two examples. A third specimen from Toxpam

(Sallé) may possibly be a female of it, but more probably is a male of another allied

species.

14. Kugnamptus hirtellus, sp. n.

Longulus, testaceus, longius setosus ; capite prothoraceque dense fortiter punctatis; elytris seriatim punctatis,

punctis valde approximatis, plus minusve confluentibus, interstitiis sat latis, sutura anguste fuscescente.

Long. cum rostro 5 millim.

Hab. GuateMaLa, Volcan de Agua 10,000 feet (Champion).

@. Rostrum as long as the thorax, rugose; eyes rather large, moderately distant, the

space between them very coarsely and closely punctured. Antenne very long. Thorax

slender, but not cylindric, deplanate above, extremely coarsely punctate, streaked with

black at each side. Elytra with the punctures in the series large, and so closely placed

as to have only irregular interstices between the punctures of each particular series, the

serial interstices rather broad, but irregular, little convex.

The only example of this species is in bad condition, but the species will be easily

recognized by its coarse sculpture, which is less regular than usual, and by its elongate

sete.

15. Hugnamptus nigricornis, sp. n.

Longulus, fulvo-rufus, setosus, nitidus ; antennis valde elongatis pedibusque nigris, femoribus rufis ; prothorace

parce punctato, nitido ; elytris seriatim sat subtiliter punctatis, interstitiis remote subtilissime punctatis.

Long. cum rostro 6 millim.

Hab. Mexico, Juquila (Sailé).

é. Antenne very Jong, with very slender club, the terminal joint of which is slightly

shorter than the tenth joint. Rostrum very short, not so long as the head, the latter

almost impunctate. ‘Thorax slender, much longer than broad. Elytra with very

regular series of not distant punctures, the interstices broad and quite flat.

We have obtained only one specimen of this species, but I believe it to be a male,

though there is nothing to indicate this with certainty. It is allied to EZ. cinctus, from

which it differs in colour, and in this respect resembles £. divisus, from which it may be

readily distinguished by its elongate form and numerous other details.

Longulus, parce setosus, niger, elytris cyaneis, vertice rufo; elytris subtiliter seriatim punctatis.

Long. cum rostro 4} millim.

Hab. Mexico, Totosinapam (Sal/é).

Antenne black, very slender, with the long club rather less slender, each joint of

the club narrowed towards the base, the terminal joint much shorter than the tenth.

Rostrum short, as long as the head, the eyes very prominent, the head almost im-

punctate. Thorax very slender, but slightly conical, sparingly subobsoletely punctate,

shining. Elytra very elongate, with very regular series of fine punctures, the interstices

broad, flat, without any distinct punctuation. Legs very slender, the middle tibie of the

male strongly curved. In the female the eyes are rather smaller and more distant.

One of the most slenderly-formed members of the genus. It was labelled in Sallé’s

collection E. rufifrons, Chevr. Three examples.

17. Eugnamptus niger, sp. n.

Hab. Mexico, Ventanas and Refugio in Durango (//ége).

Antenne moderately long, the club not linear, each joint being narrowed towards

the base, the terminal joint quite acuminate, shorter than the tenth. Rostrum rather

longer than the head; eyes large, approximate to the neck, the space between them

finely punctate at the sides, smooth and shining on the middle. Thorax rather slender,

moderately finely and not closely punctate. Elytra blue-black, shining, the punctures

in the series rather closely placed. Legs very slender. |

Allied to E. rufifrons, but independently of the colour of the head it differs in

numerous details. We have received only two specimens, which I presume are males,

the apex of the middle tibia being slightly produced internaily and acuminate.

18. Eugnamptus longulus, sp. n.

Longulus, cyaneus, griseo-setosus, nitidus, antennis pedibusque nigris ; prothorace gracili, parce, haud subtiliter

Long. cum rostro 5-6 millim.

Hab. Mexico, Parada, Juquila (Sal/é), Oaxaca (Hége).

Closely allied to £. niger, but more elongate in form, with the surface of a beautiful

blue colour, and with the punctures of the thorax so slightly impressed that they are

indefinite and the surface irregular. The four examples received include both sexes,

the male having the middle tibia incurved and strongly acuminate at the inner angle.

Hab. Panama, Bugaba (Champion).

Rostrum about as long as the thorax. Club of the antenne elongate and very slender,

the terminal joint more than half as long as the tenth, the apical portion of the latter

joint, as well as the following one, yellow. Head short, the eyes very large, the space

between them almost impunctate. Thorax very slender, coarsely and rather closely

punctate. Elytra yellow, with a black lateral stripe, and a second dark stripe near the

suture, this inner stripe indefinitely prolonged beyond the middle and imperfectly

connected with a black mark joining the outer stripe; the punctures of the series are

large, very deep, and closely placed. Legs red, the hinder and middle tibie a little

infuscate at the apex externally. Two specimens.

Hab. Guatemata, Panajachel 5000 feet (Champion).

Club of the antenne slender, but with each of the joints narrowed towards the base,

the joints preceding the club very long, the terminal joint only a little shorter than the

tenth. Rostrum very short, shorter than the head, densely rugose. Eyes large, the

space between them very densely rugose. ‘Thorax slender, with excessively dense, coarse,

rugose sculpture. FElytra with deep striation and rugose interstices, the intercalated

series at the base of the first interstice unusually elongate. Legs long and slender.

Only one specimen has been obtained of this extremely distinct species; this was

found upon the margin of the Lake of Atitlan.

Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion).

Rostrum somewhat longer than usual. Head short, the constriction of the neck

being near to the eyes, these large, widely separated, the space between them very ~

sparingly punctate. Antenne quite black, with extremely long club, the joints of which

are linear, the terminal joint only about half as long as the tenth. Thorax coarsely,

rather deeply, and closely punctate. Elytra black, the lateral margin red, bearing a

long griseous setosity; the punctuation deep, coarse, and very close, but not perfectly

regular as in L. brevicollis, the interstices very narrow and rendered somewhat indefinite

by the interstitial punctures being only imperfectly separated from the coarse serial

sculpture. Legs red, with the tips of the femora a little infuscate.

I do not detect any sexual distinction among the four specimens from which I

describe this species ; they are probably all of the female sex.

23, Eugnamptus suturalis, sp. n.

Rufus, griseo-setosus ; antennis, pedibus ex parte majore elytrisque nigris, his vitta suturali anterius latiore

rufa, densius, fortius profundiusque seriatim punctatis.

Long. cum rostro 5 millim.

Hab. Panama, Volcan de Chiriqui, Boquete, Caldera (Champion).

Closely allied to E. nigripennis, but with the club of the antenne rather less elongate ;

the elytra with the sculpture rather less deep and rugulose, especially on the apical

portion, and the suture, as well as the outer margin, red; the tibie and tarsi quite

black, the femora black at the extremities, the black colour extending nearer to

the base on the upper than it does on the lower aspect. Four examples.

Our collections also contain an example of another species from Bugaba allied to

this and to E. nigripennis, but it is in too decayed a condition to describe from.

rather longer than the thorax in one sex, shorter in the other. Eyes not very large,

rather widely separated. Head elongate. Thorax very narrow, subcylindric, closely,

very coarsely punctate. Llytra slender, with very regular series of coarse deep punc-

tures. Legs slender, clothed with erect hairs.

This insect has somewhat the appearance of the more slender of the species of

Deporaus. It differs in many respects from Z. niger, our only other black Eugnamptus

without spots or marks. We have received only two mutilated examples.

moderately large ; head sparingly punctate. Thorax short, about as broad as long, very

coarsely, not densely punctate. Elytra with regular rows of very densely packed large

and deep punctures. Legs black, the base of femora bright red, the tarsi obscure red.

We have received eight examples of this very distinct species.

26. KEugnamptus cornutus, sp.n. (Tab. III. fig. 1.)

Hab. Mexico, Chilpancingo in Guerrero 4600 feet (H. ZH. Smith).

Antenne quite black, long, the club not very long. Head elongate, quite sparingly

punctate. ‘Thorax bright red, rounded at the sides, sparingly punctured. Elytra with

quite regular series of coarse punctures, the interstices not punctate but setose, the

first at the base with about seven intercalated punctures.

We have received only one example of this species; it is probably a male, The

structure of the front of the rostrum is unique, but the curious horn is not conspicuous

owing to its being depressed.

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

Antenne flavous, rather short, the club with each joint narrowed to the base, the ter-

minal joint a good deal shorter than the tenth. Rostrum very short, not so long as the

head ; eyes very large, but little separated, placed near to the thorax, the space between

them very densely punctate. Thorax very slender, conico-cylindric, extremely densely

punctate, quite dull. Elytra with deep broad stria, which are closely and coarsely

punctate. Legs rather short, quite pale; middle tibie of the male distinctly curvate.

The four specimens obtained are possibly all males. The Mexican insect will probably

prove to be a distinct species, but only one specimen has been received of it.

28. Kugnamptus antennalis, sp. n.

Testaceus, pubescens, antennarum clava elongata fusco-testacea, prothorace elytrisque indeterminate fusco-

signatis ; elytris seriatim fortiter punctatis, interstitiis sat latis, haud omnino planis.

Long. cum rostro 3? millim.

Hab. Panama, Volcan de Chiriqui 3000 to 4000 feet (Champion).

Antenne with very long club, the terminal joint of which is, however, scarcely half

as longasthe tenth. Rostrum short; eyes very large, the space between them sparingly

and finely punctate. Thorax very slender, conico-cylindric, densely, moderately coarsely

punctured, with a vague darker mark on each side. Elytra short, the punctures of

their series moderately large and close.

This insect is similar to £. salvini, but is distinguished from it and the other species

of this group by the more elongate ninth and tenth joints of the antenne, and by the

less distinct striation of the elytra. We have received only two examples, and I am

not sure whether the vague marks of infuscation may not be due to decay.

29. Eugnamptus latifrons, sp. n. (Tab. II. fig. 13.)

Brevior, testaceus, breviter pubescens, antennarum clava fuscescente; elytris profunde lateque striatis, striis

dense et fortiter punctatis ; capite prothoraceque crebrius fortiusque putictatis.

Long. cum rostro 4 millim.

Hab. Guatemata, Panajachel 5000 feet (Champion).

This differs from £. salvini in having a broader thorax and a more coarsely and less

densely punctured head and thorax, and antenne with fuscescent club. The only

specimen obtained is no doubt a female; it has the rostrum quite as long as the thorax,

the eyes rather large, widely separated. The species is really nearer to E. truncatus,

but has a broader thorax and a more densely punctured head.

long club, the tenth joint somewhat shorter than the ninth, the terminal joint not very

long, a good deal shorter than the tenth. Thorax very densely punctate, but shining.

The colour is probably variable, as the extent of yellow on the disc of the elytra is not

quite the same in the two individuals.

Two specimens of uncertain sex.

31. Kugnamptus germanus, sp. n.

Angustus, testaceus, breviter pubescens, elytris externe fuscescentibus ; capite parce punctato; prothorace

Long. 37 millim.

Hab. GuatEMALA, Chiacam and San Juan in Vera Paz (Champion).

This insect has a much narrower head than £. latifrons and E. truncatus, and also

entirely yellow antenne, but it appears to be very closely allied to them. The club of

the antenne is rather long; the eyes are moderately large and somewhat distant, the

space between them coarsely and sparingly punctate; the thorax is quite slender,

closely and coarsely punctate. Two specimens.

Niger, subtilissime pubescens, prothorace rufo, elytris cyaneo-nigris.

Long. cum rostro 43 millim.

Hab. Mexico, Omilteme in Guerrero 8000 feet (1. H. Smith, July 1888).

Antenne elongate, but with rather short club of three slender, subequal joints.

Rostrum broad at the apex, only about half as wide near the eyes, longer than the

thorax in one sex, rather shorter in the other; head elongate, subglobose, rather

regularly and deeply punctate; eyes not very large. Thorax slender, rather long,

nearly cylindrical, bright red, somewhat coarsely, but not densely or rugosely, punctate.

Elytra with regular series of coarse punctures, and with an intercalated series at the

base of the first interstice, interstitial punctuation imperceptible. Tarsal lobes dilute

piceous.

We have received only two specimens, but they no doubt are male and female, as in

one individual the rostrum is broader and much longer than in the other.

This genus has not been accepted by entomologists, but it is certain that Auletes,

with which it is usually associated, must be divided; for if not, the other genera of the

subfamily cannot be distinguished by any definable characters. The species of Auletes

and Auletobius are all minute insects, and are scattered over most parts of the world,

but are much neglected.

Rostrum stout, rugose-punctate, opaque; eyes very convex, well separated from the

thorax, the space between them faintly senescent, flavo-pubescent, closely punctate.

Thorax slightly longer than broad, rounded at the sides, densely punctate, quite dull.

Elytra sparingly punctate, obscurely variegate, the colour being more red near the base,

fuscous towards the extremity ; the pubescence is closer and denser on the basal region.

Legs yellow. Under surface clothed with pale griseous hairs. Three specimens; in

the female the rostrum is a little longer and less rugose.

Subfam. PTEROCOLINZ.

This subfamily has hitherto consisted of a single species found in North America.

Its position has been much disputed, Schénherr placing it with the Attelabide, Lacor-

daire treating it as a separate tribe placed next Ceuthorhynchides, while Leconte

placed it as a subdivision of Rhynchitide. In reality it is a very isolated form, linking

the Attelabide satisfactorily with the Baridiide. The prosternum has the apices

of the epimera widely separated by a broad process as in Baridiide and Attelabide.

From the former group it differs by its straight antenne, but is connected with it by a

peculiar undescribed genus from our region; from Attelabide the subfamily differs by

the small coxe and the large mesosternum with extraordinarily developed side-pieces.

Antenne with the very loosely articulated club as long as the rest of the joints.

Head brassy ; rostrum very short, not longer than the head. ‘Thorax of a dark golden

colour, densely punctate, finely pubescent. Elytra rather closely punctate, and with

series of punctures placed in very shallow grooves that become quite obsolete behind ;

about the epipleure with some golden pubescence. Underside of a pallid steel-blue

Niger, supra cyaneus, tenuissime pubescens, fortiter sculpturatus.

Hab. Mexico, Yolotepec, Parada (Sal/é), Acapulco (Hége).

Rostrum black, shining, longer than the head; antenne with broad club, the first |

two joints of which are transverse. Thorax much narrowed in front, densely and

coarsely punctured, the punctuation substrigose longitudinally. Elytra with deep,

broad grooves, which are coarsely sculptured ; interstices impunctate.

Only one example has been procured in each locality. These do not exhibit any

sexual distinctions on the ventral segments, but the individual from Acapulco is

smaller and has a shorter rostrum; it may be the male, if not it must belong to

another species. JP. grossus is a little larger than P. auricollis.

APTEROCOLUS, gen. nov.

Elytra ad suturam valde abbreviata, segmentis dorsalibus abdominis quinque visibilibus.

This genus is closely allied to Péerocolus, but has five of the dorsal segments exposed

instead of three, the posterior coxz very widely separated, though the anterior pair are

more approximate, and the rostrum furnished with very deep lateral scrobes, which are

not visible from the front, as the edge of the rostrum projects over them; similar

scrobes exist really in Péerocolus, but owing to the antenne being inserted nearer to

the eyes the scrobes are much less conspicuous than in Apterocolus.

Latissimus, chalybeo-niger, fortiter sculpturatus, antennis articulis 2° ad 5™ piceis.

Long. cum rostro subporrecto 43 millim.

Hab. Mexico, Cuernavaca (Sallé, Hoge).

Antenne short, with large broad three-jointed club, the eighth joint transverse, the

first two joints of the club each strongly transverse. Rostrum moderately long, much

longer than the head. Thorax elongate, much narrowed in front, coarsely and closely

punctured. Elytra with broad, deep grooves, which are coarsely sculptured ; interstices

narrow and shining. Exposed parts of the dorsal segments coarsely punctured, the

terminal segment so much deflexed as to be not visible from above. Legs thick; the

spurs of the hind tibize conspicuous.

Only two examples have been received of this remarkable Curculionid. The male

has the ventral plates deplanate on the middle and covered with long white pubescence.

In the female the apical portion of the rostrum is slightly longer than it is in the male.

Our figure represents this latter sex.

Subfam. nov. AL LOCORY NINA.

The rostrum is very slender, quite cylindrical, a little curved, somewhat longer in one

sex than in the other. The antenne are inserted close to the eyes on the underside of

the rostrum; they are not in the least geniculate, and bear a very laxly articulated

three-jointed club; the basal joint is as long as the following three together. The

parts of the mouth are very small, but there is a very elongate peduncle to the mentum,

the palpi are extremely minute, and the very small mandibles exhibit no trace of any

angles or projections on their outer surface. The pronotum is flat, but has not lateral

margins; the prosternum is very short, nearly all its length being occupied by the

anterior coxe ; these latter are subglobose, but extend somewhat in the lateral direc-

tion, and project very little perpendicularly. The sutures of the prosternum behind the

coxa are minute, much consolidated, and very difficult to see; but I think there is a

very small centrosternal piece, and that the apices of the epimera very nearly but

not quite meet behind it. The middle coxe are round, rather large, not at all exserted,

distinctly but not widely separated. Metasternum of moderate length. Hind coxe

contiguous, transverse, rather large. Abdominal ventral segments five in number,

subequal in length ; in addition there is a very minute, frequently retracted, terminal

segment. ‘The sides of the ventral plates do not form any edge in apposition with the

elytra, but are much infolded on the dorsal surface, and the side-margins of the elytra

are free. The epipleuree become gradually narrower from the shoulders to one half of

the length of the elytra and there disappear altogether. The apices of the elytra are

separately rounded and leave the pygidial segment exposed. ‘The tarsi are broad, and

in form more like those of a Clavicorn than of a Rhynchophorous insect, the first and

second joints being short and broad, the third bilobed, the fourth joint small but quite

visible between the lobes of the third joint; the terminal joint large, with rather

large claws; each of the joints 1—3 is furnished on either side with rather long: hairs,

which project laterally as well as downwards. Hind femora very broad, their upper

margin strongly arcuate, crenulate. |

I am compelled to establish a new subfamily for the abnormal weevil from which

the above characters are taken, the best place for which is near Rhynchitine, although

no affinity is exhibited with any particular genus of that subfamily, and it differs

strongly from the aberrant forms of Rhynchitine by the minute palpi and trophi.

In appearance this singular insect is not at all similar to any other Curculionide

known to me, though it has several characters of the Oxycorynides of Lacordaire,

from which it differs by the unmargined sides of the pronotum, by the largely developed

basal joint of the tarsi, and the exposed pygidium.

ALLOCORYNUS, gen. nov.

Antenne rect, basales. Rostrum gracile, cylindricum. Coxe anteriores contigue, subglobose, parum exserte.

Rostrum of the male slightly longer than the thorax, punctulate, not shining; of the

female as long as the head and thorax, more slender, impunctate, shining. Eyes coarsely

granulate, large, and prominent; the space between them somewhat coarsely punctate.

Antenne rather longer and more slender in the female than in the male; second joint

shorter than the first ; terminal three joints forming a large, very loosely articulated club,

the first joint of which is the largest, the apical joint being much smaller, acuminate,

without any trace of division or constriction. ‘Thorax strongly transverse, rounded at

the sides and narrowed in front, finely and rather sparingly punctate. Scutellum sub-

quadrate. Llytra elongate, but leaving the terminal segment quite exposed, punctured

like the thorax ; the apices separately rounded.

Herr Hoge procured a small series of this obscure, unattractive, but interesting little

insect. Unfortunately nearly all of them are so immature as to be nearly valueless.

APION. 47

Subfam. APIONINAEL.

APION.

Apion, Herbst, Natursyst. Kaf. vii. p. 100 (1797).

This familiar genus is one of the most extensive in the order; fully 500 species

have been described, notwithstanding the fact that owing to their minute size they

are usually neglected both by the collector and describer. Although the majority of

the species that have been catalogued belong to the European region, yet it is ascertained

that the genus is of very wide distribution, and it is probable that it is really as rich in

species in tropical regions as it is in Europe. Only three species have been described

previously from Mexico or Central America, and I now add upwards of eighty others

to this number, though I have left undescribed a large number of specimens that

appear to represent different species, only one or two examples of each being present ;

so that it may be said that evidence has already been obtained of the existence of about

200 species of Apion in our region.

The difficulties in the way of a satisfactory treatment of the genus have been fre-

quently alluded to, but have never been overcome, and no satisfactory way of grouping

the species or of sectionizing the genus has been discovered. In order to facilitate the

determination of the species here described, I have placed together all those with

black legs in one group, and those in which the legs are not entirely black in another ;

and I have commenced each of these two divisions with the species that have the

antenne inserted quite at the base of the rostrum, placing at the end of each division

those that have the antenne most distant from the base. Although this arrangement

is very far from satisfactory, I think it less likely to mislead than any other I can at

present devise. |

As a rule, the colour of the legs is very. constant in each species, but still there are

one or two in which it is variable, and also one or two in which it is doubtful whether

the legs are entirely black or not; and there are even a small number of cases in which

allied species are by this character referred to different divisions.

Division A.

Legs entirely black (in one or two species the tibie are dark piceous).

Species 1-36.

The species placed at the commencement have the antenne inserted at the base of

the rostrum very near to the eyes, those at the end of the division have the antenne

inserted near the middle of the rostrum.

For the identification of this species an inspection of the type—which is in

Chevrolat’s collection—is necessary. Having black legs and the antenne inserted at

the base of the rostrum, I place it here.

in June (Z/. H. Smith); GuaTeMaua, near the city, Aceituno (Champion) ; Nicaragua,

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

One of the smallest and most obscure species of the genus, and without any salient

distinctive character. The rostrum is not very different in the two sexes, but in the

male is a little shorter—not much longer than the thorax—and not so smooth and

shining as in the female; it is curved and strongly deflexed. The eyes are scarcely at

all prominent, the interval between them is rather narrow ; the antenne are inserted near

the eyes, only about as far in front of them as the width of the interval between them.

The thorax is rather strongly transverse, not much narrowed in front, feebly constricted

in front of and behind the middle. The elytra are short, much broader than the thorax,

deeply sulcate, with narrow interstices. There are no distinct white sete round the

eyes, and none on the sides or front angles of the breast.

This minute insect is probably the most abundant of the genus in our region; a good

series was found at Teapa, at Chontales, and on the Volcan de Chiriqui.

3. Apion preeditum, sp. n.

Minutum, minus breve, nigrum, opacum, parce, minute griseo-setosum ; rostro mediocri, antennis basi fusces-

Hab. GuateMaua, Aceituno, Dueiias (Champion), Coban (Conradt).

This insect is very similar to A. spretissimum, but will be readily distinguished by the

peculiar male structure at the extremity of the hind body ; it has, too, the rostrum rather

longer—its length in the female being equal to that of the head and thorax; the form is

narrower, and the hairs or scales of the upper surface are not of so pure a white colour.

The eyes are slightly prominent. The rostrum in the female is slender-cylindrical, and

APION. 49

shining from the insertion of the antenne forwards; while in the male it is less cylin-

drical, and only becomes shining in front. The prothorax is a good deal narrowed in

front, not so long as it is wide at the base, with the punctures rather distant and very

ill-defined ; it has a short obsolete channel at the base on the middle.

Long. 1 millim. absque rostro.

Mas tarsis intermediis articulo basali subtus mucrone armato.

Hab, GuaTEMALA, near the city, San Geronimo (Champion).

Rostrum in the male rather thick and about as long as head and thorax, in the

female rather more slender and elongate; the eyes are small and very little promi-

nent, placed very near the thorax; the antenne are short, inserted quite as far in front

of the eyes as the width of the interocular space, they are of a dark fuscous colour,

with the club black. ‘The thorax is rather broad and short, a good deal narrowed in

front, very dull, with distant, rather large punctures, and in front of the scutellum

a minute canaliculiform fovea. Elytra with the sculpture deep, the interstices narrow,

convex. Under surface with no condensation of sete on the breast or beneath the

orbits.

Two pairs of this species were obtained ; the peculiar structure of the basal joint of

the middle tarsus will enable it to be identified with certainty so far as the male sex is

concerned.

5. Apion nitidirostre, sp. n.

Breve, coleopteris subglobosis, nigrum, nitidum, nudum; rostro gracili, polito; prothorace parce obsolete

Hab. Panama, Bugaba (Champion).

Rostrum in the male as long as head and thorax, in the female a little longer; free

from sculpture and very shining; eyes convex, placed very near the thorax, the interval

between them moderately wide; antenne inserted very near to the eyes. Thorax short,

greatly narrowed in front, sparingly and obsoletely punctate, without impression in

front of the scutellum. Elytra short, broad and convex, finely striate. Legs short.

A species not closely allied to any other from our region; the very shining rostrum,

with antenne inserted near the base, the sublevigate thorax, and the finely striate elytra

are sufficient to distinguish it. Only three specimens have been obtained.

short, inserted very near to the eyes. Thorax small, slender, distinctly narrowed

towards the front, moderately closely, subobsoletely punctate. Elytra deeply sulcate,

with convex interstices. Under surface sparingly pubescent; middle coxe well sepa-

rated. Three specimens.

The red colour of the elytra appears to be a ready means of identifying this insect,

which in other respects is a very obscure species.

Hab. Panama, Bugaba, Tolé (Champion).

Rostrum of the male dull, somewhat finely punctate, rather thick, a little shorter than

the head and thorax; of the female impunctate, slender, curvate, but little shining,

a good deal longer than the head and thorax; eyes convex, rather large, the interval

between them coarsely punctate, narrow; antenne short, obscure yellow, with the club

dark, inserted near the base but at a rather greater distance in front of it than the

width of the interocular space. Thorax short and broad, greatly narrowed in front,

rugosely and coarsely punctate, with a very short channel or fovea in front of the scu-

tellum. llytra short and broad, moderately deeply sulcate, the interstices quite flat.

Under surface with very little setosity; middle coxe rather widely separated.

We have received thirteen examples of this obscure little insect ; it most resembles

A. vetustum, but is not closely allied thereto, and is readily distinguished therefrom by

the broader head and more convex eyes, as well as by the insertion of the antenne

nearer to the base of the rostrum.

with the punctures in the strie deep and approximate, the interstices much broader

than the grooves. Legs elongate and slender. Male with the hind tibia furnished at

the apex beneath with a strong mucro, and there is a less conspicuous mucro on the

middle tibia. The shining, metallic thorax and elytra, with only very scanty and

minute hairs, and the long rostrum, legs, and antenne, will lead to the recognition of

this species. Ten examples have been met with.

Long. 2 millim.

Hab. Panama, David (Champion).

We have received five examples of this Apion, but I do not detect any sexual distinc-

tions ; it is allied to A. guatemalenum, but has the elytra differently sculptured. The

rostrum is slender, moderately curved, shining black, rather longer than the head and

thorax ; the eyes are very prominent, the interval between them wide; the antenne

are inserted about as far in front of the eyes as the width of the ocular interspace.

The thorax is small, narrowed in front, coarsely but not rugosely punctate, with a

shallow depression at the base in front of the scutellum. The elytra are short, not

sulcate, but with strongly marked strie, which have an interrupted appearance due to

the punctures in them. The middle coxe are approximate.

10. Apion stabile, sp. n.

Angustulum, elongatum, nigrum, opacum, setulis albidis sparsum; rostro mediocri, minus gracili, antennis

Long. 2 millim.

Hab. Guatemaua, San Gerdénimo 3000 feet (Champion).

This differs from A. preditum and A. spretissimum by the thicker rostrum and more

cylindrical thorax, and by the antenne being inserted a little farther from theeyes. The

sexes seem to differ very little from one another. The rostrum is curved, black, shining,

but quite distinctly punctate in each sex, in the male its length is slightly less and the

punctuation is slightly more defined than in the female ; the eyes are small, rather widely

separated, and are placed at a considerable distance from the front of the thorax. The

thorax is slender, scarcely at all narrowed in front, and has a canaliculiform fovea in

front of the scutellum. The little white sete on the elytra and on the surface generally

are very conspicuous, and the front of the breast on each side anterior to the middle

coxe is covered with them. Ten examples.

Hab. Mexico, Jalapa (/ége).

There is but little difference between the sexes in this species; but the male has the

middle and hind tibie mucronate at the apex, and the rostrum not quite so long as the

head and thorax, while in the female it is about as long as the head and thorax.

Rostrum stout, sulcate on each side; antenne inserted near to the eyes, these latter

convex, the interval separating them only moderately broad, and bearing three or four

fine strie. ‘Thorax greatly narrowed from the base to the front, very coarsely punctate,

with a very short channel in front of the scutellum. Elytra convex, much broader than

the thorax; the grooves rather fine and not very deep, bearing distant, remote punctures,

the intervals flat and rather broad. Legs stout. ‘The pubescence of the under surface

less scanty than that above, but still not close. Three specimens.

Hab. Panama, Taboga Island (Champion).

We have received only two males of this species, but as it will be recognized without

much difficulty—not being very near to any other—I have described it. The middle

and hind tibie are mucronate at the apex, but the mucrones are slender spurs directed

straight downwards, not inwards as in most of the other species. The rostrum is rather

thick, curvate, densely sculptured except at the tip; the antenne are inserted not very

far from the eyes, being separated from them by not quite one fourth of the length of

the rostrum ; the eyes are rather large and prominent, placed close to the thorax, the

interval between them moderately broad. The thorax is rather broad, much narrowed

towards the front, scarcely at all impressed at the sides, moderately closely and coarsely

but obsoletely punctate, with a small fovea in front of the scutellum. Elytra short

and broad, coarsely striate, though the striz are scarcely deep enough to be called sulci,

the interstices rather broad, flat. ‘The white setosity is not quite so scanty on the under

surface as it is above, and under the orbits is a little more conspicuous.

Rostrum about as long as the head and thorax, rather stout, punctate above, beneath

deeply bisulcate in front of the insertion of the antenne; eyes not convex, the interval

between them rather narrow, bisulcate; antenne stout, inserted much on the under

surface, about as far in front of the eyes as the width of the interval between these.

Thorax greatly narrowed in front, not polished, but with a silky lustre, and only remotely

and very finely punctate, without channel or fovea. Elytra shining, deeply striate, but

with the strize scarcely deep enough to be called sulci, deeply punctate. Legs stout.

We have received a series of about twenty specimens of this species, but I am not

able to distinguish the sexes with certainty; it is not likely to be confused with any

other of our Apions, its size being much larger than that of the following species.

but at a greater distance from them than the width of the interocular space. ‘Thorax

rather short and broad, very strongly narrowed in front, very definitely, but neither

closely nor coarsely, punctate, with a minute channel in front of the scutellum. LElytra

short and broad, somewhat deplanate at the base, very distinctly striate, the strize with

very fine remote punctures, and thus appearing crenate. Legs short; middle coxe

Besides differing from A. championi in its much smaller size, this insect has no

dilatation of the basal portion of the rostrum. This organ is about as long as the head

and thorax, only moderately stout, shining, feebly sculptured; the eyes are rather

small, slightly convex, the interval between them moderately wide; the antenne have

the base of the first joint yellow, they are inserted considerably behind the middle of

the rostrum, but at a greater distance from the eyes than the width cf the interocular

at a greater distance from it than the width of the interocular interval, the basal joint

tawny. ‘Thorax nearly as long as broad, a little rounded at the sides, not narrowed

in front; the surface almost dull, with numerous rather large but not deep punctures ;

more distinctly brassy than the thorax; interstices quite flat. Under surface without

white sete beneath the eyes, with a slight white pubescence at the sides of the breast.

One example from Mexico, three from Guatemala; if I have the sexes before me,

APION, 55

as I suppose, the male differs from the female only in having the rostrum rather

shorter.

This is a very obscure little Apion, but its form is more slender than that of most of

the species whose descriptions resemble it.

18. Apion tantillum, sp. n.

Angustum, nigrum, subnitidum, elytris subanescentibus; rostro opaco, sculpturato, basi lato; prothorace

angusto, subcylindrico, dense fortiter punctato; elytris sat profunde, anguste sulcatis.

Long. 12 millim.

Hab. GUATEMALA, near the city (Champion).

Rostrum nearly as long as the head and thorax, curved, thick, broad and flat at the base,

unusually dull owing to a dense, fine sculpture ; antenne inserted rather farther from

the eyes than the width of the interval between these ; eyes not prominent, small, the

head narrow, though the space between the eyes is rather broad; this space is quite

flat, densely and indistinctly punctured. ‘Thorax slender, not narrowed in front, the

punctuation close, coarse, and distinct. Elytra narrow, but much broader than the

thorax, their grooves moderately deep, rather narrow, indistinctly punctured. Middle

coxe contiguous.

We have received three examples of this obscure Apion; they do not exhibit any

sexual distinctions. The broad, flat base of the rostrum, its peculiar dull surface and

fine sculpture are rather peculiar.

19. Apion lassum, sp. n.

Angustum, subnitidum, nigrum, elytris subsenescentibus ; rostro mediocri, cylindrico, sat nitido; prothorace

minus gracili, subcylindrico, fortiter punctato ; elytris sat profunde sulcatis.

Long. 2 millim.

Hab, GuateMaLa, Chiacam (Champion).

Rostrum a little longer than the head and thorax, moderately stout, cylindrical,

shining, except at the base; antenne inserted a little farther from the eyes than

the width of the space between them ; eyes a little prominent, the interocular space

moderately broad, feebly striate. ‘Thorax only very slightly narrowed in front, closely

and coarsely punctured, with a short channel in front of the scutellum. Elytra

narrow, rather deeply sulcate, the grooves distinctly punctured, the interstices rather

narrow. Middle coxe distinctly separated. Two examples.

This bears some resemblance to Apion guatemalenum, but is a narrower insect and

less shining; the two are not likely to be confounded when seen side by side. A. lasswm

is, however, probably a species intermediate as regards the colour of the legs between

the two divisions into which I have divided the genus, as there is a slight deficiency of

black colour on the anterior tibiz, so that the expression “Jegs entirely black” is not

quite satisfactory in the case of this insect.

20. Apion mediocre, sp. n.

Angustulum, nigrum, opacum, sat sparse griseo-setosum ; rostro subelongato, cylindrico, nitido; prothorace

crebre, fortiter, parum argute, punctato ; elytris profunde sulcatis, interstitiis subplanis.

Long. 23-24 millim. absque rostro.

Hab. Mexico, Omilteme in Guerrero in July (H. H. Smith).

Rostrum in the male scarcely so long as, in the female a little longer than, the head and

thorax; head moderately short and broad; eyes somewhat prominent, separated by a

rather wide space ; antenne inserted very near to the eyes, not farther in front of them

than the width of the interocular space. Thorax rather slender, a good deal narrowed

in front, feebly constricted anteriorly and near the base, somewhat coarsely and mode-

rately closely, but vaguely, punctured, with a moderately elongate channel on the

middle. Elytra rather long and narrow, quite dull, moderately broadly and deeply

sulcate. Under surface with but little concentration of pubescence on the sides of the

breast or under the eyes. Male with a large mucro at the apex of the hind tibie, and

a rather smaller one on the intermediate tibie.

This insect is destitute of any salient characters; there are apparently several other

species closely allied to it, of which we have received only single specimens, and which

I therefore do not think it proper to describe.

21. Apion hystriculum, sp. n.

Flongatum, nigrum, haud perspicue subsenescens, opacum, minus tenuiter griseo-setosum, utrinque prope scu-

tellum pubescentie pallide macula parva; rostro mediocri, maris hirsuto; prothorace sat crebre, fortiter

punctato; elytris interstitiis latis, planis; subtus dense pallido-setosum.

Long. 24-3 millim.

Hab. Mexico, Xucumanatlan 7000 feet and Omilteme 8000 feet, both in Guerrero

(Hf. H. Smith).

This differs from A. mediocre by the more dense clothing of hairs, by the fact that at

the base of the elytra on the second interstice they are concentrated so as to form a small

_ pallid spot, and by the rostrum of the male being densely setose except at the tip. The

antenne are quite black, and are inserted very near the base of the rostrum; this latter

in the male is but little longer than the thorax, rather stout, in the female it is as

long as head and thorax, slender, and nearly free from hairs; the eyes are moderately

large, somewhat distant from the thorax, and the interval between them is comparatively

broad. The thorax is rather narrow, much narrowed anteriorly, and feebly transversely

constricted in front, its punctuation is rather close and deep. LElytra elongate, finely

sulcate, the sulci not deep, the interstices broad and flat. Under surface bearing much

white setosity ; this is dense and conspicuous under the orbits. Middle and hind tibie

of the male with a rather long mucro at the inner margin of the extremity.

Elongatum, nigrum, opacum, tenuissime setosum; rostro elongato, gracili, polito ; oculis sat prominulis ; pro-

thorace transverso, fortiter punctato, anterius et posterius leviter transversim constricto; elytris sulcatis,

Long. 23 millim.

Hab. Mexico, Amula in Guerrero in August, Chilpancingo in July (H. H. Smith) ;

GuaTEMALA, San Gerénimo (Champion).

Rostrum slender, without sculpture, polished, curvate, much longer than the head and

thorax ; eyes rather prominent, a little distant from the thorax, and separated by a

moderately wide interval ; antenne elongate, inserted about as far in front of the eyes

as the width of the neck, the basal joint dark yellow. Thorax with coarse, rugose

punctuation, and with a fine, short channel in front of the scutellum. Elytra deeply

grooved, and with very definite large impressions in the grooves. Legs elongate ;

middle coxe but little separate.

The five examples received of this species are, I presume, all of the female sex.

Mr. Champion procured two or three very similar specimens at Cerro Zunil, having,

however, the sides of the rostrum punctate: these may possibly be males of A. gracili-

rostre, but I think they are more probably females of an allied species.

23. Apion punctulirostre, sp. n.

Sat elongatum, nigrum, subopacum, tenuiter albido-setosum ; rostro elongato, gracili, cylindrico, punctulato ;

convexis.

Long. 24 millim.

Hab. Mexico, Cuernavaca in Morelos in June (H. H. Smith).

This insect certainly comes very close to A. gracilirostre; the rostrum, however, is not

very smooth and polished as in that species, but bears a distinct punctuation. This is

almost all I can see of importance to distinguish the two, though A. punctulirostre is a

little more slender, and has a distinct sprinkling of minute hairs or setosity on the

upper surface even on the elytra.

Two specimens. It may be well to say that there are in the collection three or four

other individuals very closely allied to this and to 4. gracilirostre, but representing, I

believe, as many distinct species.

58 RHYNCHOPHORA.

Rostrum about as long as the head and thorax, dull, rather slender, a little thicker

at the base; antenne inserted about as far in front of the base as the width of the

interval between the eyes, the basal joint yellow; eyes rather large, but only slightly

prominent, the orbit delicately margined with white cilize above, more coarsely so

below; interocular space moderately broad, striate; neck rather elongate. Thorax

slender, subcylindrical, but still a good deal narrowed in front, coarsely, deeply, and

very closely punctate, with an obscure canaliculiform impression in front of the

scutellum. Elytra long and narrow, moderately deeply and broadly sulcate, the

interstices nearly flat, at the base on each side with some conspicuous white sete

placed chiefly on the third interstice. Sides of the breast quite white with hairs.

This species will be recognized by the narrow form, black colour, and the white

hairs at the base of the elytra on each side. Five specimens have been received from

Mexico, one from each of the localities more to the south: these latter examples

have the white hairs on the elytra less conspicuous, and they may not belong to the

same species.

25. Apion laminatum, sp.n. (Tab. III. figg. 6; 6a, profile of head.)

Nigrum, opacum, parcissime setosum ; rostro sat crasso, subtus lamina elongata munito; elytris sat profunde

punctatis, interstitiis planis.

Long. 27 millim.

Hab. Mexico, Amula in Guerrero 6000 feet, in September (/7. H. Smith).

We have only received one example of this species, but it has the structure of the

rostrum so peculiar that I have thought proper to describe it. Possibly the character may

be confined to one sex, which in that case may prove to be the male, as this example

has a small mucro at the inner margin of the apex of the middle tibia. The rostrum

is scarcely so long as the head and thorax, rather stout and curvate, and is provided

beneath with a large lamina extending from the insertion of the antenne to the apex ;

the antenne are short, quite black, with unusually abrupt club, and are inserted very

near to the eyes; these latter are moderately large and are separated by a wide interval.

The thorax is rather small and narrow, much narrowed in front, closely and coarsely

punctured, with a very short inconspicuous channel in front of the scutellum. The

elytra are rather narrow, somewhat deeply but not broadly sulcate. The clothing of

the surface is very inconspicuous.

26. Apion vetustum, sp. n.

Hab. Mexico, Teapa in January and February, Tierra Colorada in Guerrero in

October, Rincon in September (Z. H. Smith) ; Guaremaua, San Gerénimo (Champion).

APION, 59

Rostrum about as long as the head and thorax, moderately stout, deflexed, a little

incrassate at the insertion of the antenna, slightly narrowed at the tip; eyes small, not

prominent, the space between them rather narrow, bearing two or three raised lines;

antenne short, inserted a little behind the middle of the rostrum. Thorax short,

transverse, a good deal narrowed from the middle to the front, densely, rugosely

sculptured, with a fine short channel in front of the scutellum. LElytra short and

broad, slightly shining, moderately finely, not deeply sulcate, the sulci deeply punctate,

the interstices quite flat. Under surface with scarcely any pubescence. Middle coxe

more widely separated than usual.

We have received sixteen examples of this species, but I cannot detect any indication

of the sexes.

27. Apion constricticolle, sp. n. (Tab. II. fig. 21.)

Angustum, nigerrimum, nitidum, nudum; rostro brevi, cylindrico ; prothorace elongato, cylindrico, anterius

et posterius transversim impresso, fere impunctato; elytris elongatis, leviter striatis.

Long. 2-23 millim.

Hab. Mexico, Atoyac in Vera Cruz in April and May (#. H. Smith); GuaTeMa.a,

near the City, Purula (Champion); Panama, Volcan de Chiriqui, Caldera (Champion).

Rostrum short, thick, not curvate, scarcely longer than the head, the antennz inserted

just behind the middle ; eyes rather small, but convex and prominent, placed much in

front of the thorax, the space between them rather broad, feebly impressed. ‘Thorax

narrow and elongate, cylindrical, but rendered irregular in outline by the two broad

depressions, which are more distinct at the sides. Klytra long and narrow, black,

shining, finely striate, the interstices broad and flat.

I can see no sexual distinctions among the extensive series obtained of this very

distinct species. Extremely little variation of any kind is exhibited, except that the

large series of examples from Purula have a very obsolete bituberculation of the

rostrum between the insertion of the antenne. In immature specimens the legs are

more or less piceous. A. longicolle and A. terminale are allied to A. constricticolle,

but as the legs are not entirely black they are placed in the next division.

Long. 3 millim. absque rostro.

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

Antenne elongate and thick, armed with long sete, inserted about the middle of the

rostrum; the base of this latter thick, sculptured, the apical portion cylindrical, smooth,

and shining; eyes convex, the interval between them wide, with a short, shallow

channel on the middle. Thorax broader than long, greatly rounded at the sides, feebly

constricted near the front and near the base, densely and coarsely punctate, with a

moderately long channel in the middle in front of the base. Elytra broad, deeply

sulcate, with a large depression in the sulci, these depressions separated only by small

intervals, the interstices moderately broad, rather convex, quite dull. Anterior legs

elongate ; tibiee dilated and compressed, set with hairs along the inner margin behind ;

middle tarsi with the second joint broad, the third very broad, its lobes divergent, so

as to receive the very short, broad fourth joint, the claws of this latter abruptly bent

and applied to the under surface of the joint; middle and hind tibie armed with a

short mucro at the apex internally.

Only one specimen of this very abnormal insect has been obtained.

29. Apion seriatum, sp.n. (Tab. III. fig. 8.)

Robustum, nigrum, opacum; rostro sat elongato, crassiusculo, punctato et striato; prothorace subconico,

crebrius fortiter punctato; elytris parum profunde sulcatis, interstitiis uniseriatim punctatis.

Long. 22 millim.

Hab. British Honpuras, Belize (Blancaneauz).

We have only received one specimen of this species; it is not like any other, and

will be easily recognized by the unusual character of a punctuation on the interstices

of the elytra. Rostrum rather longer than the head and thorax, stout, dull, punctate,

carinate at the sides; antenne short and stout, inserted about as far in front of the

eyes as the width of the head (including the eyes); these latter rather large, slightly

prominent, the interval between them narrow, tricarinate. Thorax large, almost as

broad behind as the base of the elytra, much narrowed in front, deeply and coarsely as

well as closely punctured, with a deep distinct impression in front of the scutellum.

Elytra quite dull, very definitely, moderately deeply grooved ; interstices very slightly

concave, each with a series of closely placed, rather large, but obsolete punctures.

Legs stout. Middle coxee very widely separated.

A. seriatum is really more allied to A. juno and the species near that, all of which

have the femora more or less variegate with red, and are consequently placed in the

next division.

30. Apion quercicola, sp. n.

Angustulum, nigrum, opacum, parce griseo-setosum ; rostro gracili, maris mediocri, femine elongato; capite

angusto et brevi, oculis haud prominulis; prothorace conico-cylindrico, crebre fortiter punctato; elytris

elongatis, sat profunde sulcatis, sulcis profunde punctatis, interstitiis planis.

Long. 12-2 millim.

Hab. Mexico, near the city (Flohr).

This insect resembles A. spretissimum and A. preditum, but the antenne are inserted

farther in front of the base, their distance in front of the eyes being as great as the

APION. 61:

length of the head. The rostrum in the male is curved, quite slender, rather longer

than the head and thorax ; in the female it is nearly straight, much longer, quite one

millim. in length. The punctuation of the thorax is coarse and close. The elytra are

long and narrow, with rather deep grooves or striae, the large punctures in which are

quite distinct and approximate, the interstices flat. The griseous clothing of the surface

is scanty, and there is no condensation of white hairs around the eyes or at the sides

of the breast.

A pair of this species was sent by Mr. Flohr, with the information that the insect

was obtained by beating small oaks near Mexico City. Although there is a con-

siderable difference between the two examples, yet they agree in the important character

of the point of insertion of the antenne.

31. Apion spectator, sp. n.

Sat elongatum, nigrum, subnitidum, parum setosum ; rostro elongato, gracili, nitido, maris tenuiter pubescente ;

prothorace fortiter denseque rugoso ; elytris profunde sulcatis, interstitiis subconvexis.

Long. 2-27 millim.

Hab. Guatemaa, Aceituno, San Gerdénimo (Champion).

Rostrum cylindrical, shining, in the male delicately pubescent, rather longer than

the head and thorax, in the female much longer, slender, and quite shining, though

evidently punctate ; eyes moderately large and convex, the interval between them rather

broad ; antenne quite black, inserted about as far in front of the eyes as the width of

the head and eyes. Thorax short and broad, greatly narrowed in front, very coarsely

sculptured, with a deep short impression in front of the scutellum. LElytra rather

elongate, deeply and broadly sulcate, the interstices narrow and a little convex. Under

surface sparingly clothed with white setosity. Middle coxe closely approximate. Male

with the middle tibiee mucronate at the inner margin of the apex. Eleven specimens.

The male of this species bears some resemblance to A. mediocre, but has the antenne

inserted farther from the eyes, and the hind tibie are not mucronate. A. guatemalenum

is more shining, and has a very differently sculptured thorax; while A. quercicola is

more slender, very dull, and has a much narrower head.

32. Apion fuscimanum, sp. n.

Sat elongatum, nigrum, parum nitidum, nudum, tarsis anterioribus fuscis; rostro in sexibus dissimile, maris

robusto, mediocri, punctulato, feminz elongato, nitido; oculis haud prominulis; prothorace fortiter

punctato ; elytris ad basin deplanatis, sulcatis.

Long. 2-23 millim.

Hab. Guatemata, Capetillo, Zapote (Champion).

Rostrum curvate, in the male dull, stout, as long as the head and thorax, in the

female more slender, shining, longer than the head and thorax; eyes not at all

prominent, the space between them somewhat narrow; antenne short and rather stout,

inserted as far in front of the eyes as the length of the head. Thorax dull, elongate,

narrowed in front, strongly punctate, with a short, but remarkably deep and definite

canaliculiform fovea at the base. Elytra with the basal region flat, sulcate, but not

deeply so; punctuation of the sulci indistinct ; interstices narrow, flat. Front feet and

the tip of the tibia infuscate-yellow. Middle coxee rather widely separated.

This is not at all closely allied to any other of the species here described, but

Mr. Champion found single examples of what appear to be three species very near to

this in different localities.

88. Apion altum, sp. n.

Sat elongatum, nigrum, supra eenescens, nitidum, nudum; rostro curvato, punctato, mediocri; antennis pone

medium rostri insertis; prothorace conico, crebre sat fortiter punctato; elytris striatis, striis remote

punctatis, interstitiis parce obsoleteque punctatis.

Long. 3 millim.

Hab. Panama, Bugaba (Champion).

Rostrum moderately stout, cylindrical, much curved, strongly punctate at the sides of

the base, rather longer than the head and thorax; eyes small, not prominent, the interval

between them moderately broad, coarsely punctate; antenne small, inserted behind

the middle of the rostrum, but at a distance from the eyes equal to slightly more than

one third of the length of the rostrum. Thorax regularly narrowed from the base to

the apex, definitely and moderately coarsely punctate, with a larger deep puncture

forming a minute fovea in front of the scutellum. Elytra rather elongate and more

than usually parallel-sided, very distinctly striate; looked at from the side the inner

margins of the striz appear to be raised, and the punctures they bear seem to extend

over and render irregular the outer margins of the strie.

We have received only two specimens of this distinct species. I think they are of

the two sexes, but if so the differences are only very slight.

34. Apion longimanum, sp. n. (Tab. III. fig. 9.)

Sat elongatum, nigrum, subopacum, antennis pedibusque elongatis; rostro maris mediocri; prothorace lato,

Long. 2 millim.

Hab. GuateMaLa, Cahabon (Champion).

Only one male of this species has been obtained, but the species is—in that sex at

any rate—very easy to distinguish, the antenne and legs being slender, with the club

of the former and the basal joint of the front tarsus unusually elongate; the front

and middle tibie are mucronate internally at the apex. The rostrum is moderately

stout, just as long as the head and thorax, the antennal insertion slightly in front of the

middle. ‘The eyes are not large, the interval between them moderately broad, feebly

sculptured. ‘The thorax is very coarsely sculptured, and has a small deep fovea in

APION. 63

front of the scutellum. The grooves of the elytra are deep, and are deeply punctate,

the interstices being only about as broad as the sulci. There is but little setosity on

the under surface, and the middle coxe are closely approximate. The mucro on the

front tibia is very conspicuous, being directed strongly inwards.

Hab. Muxtco', Chilpancingo in Guerrero 4600 feet in June (H. H. Smith).

Antenne long and slender, the basal joint elongate, inserted slightly behind the middle

of the rostrum ; this latter cylindrical, somewhat longer than the head and thorax: eyes

rather large and convex, placed but little away from the thorax, the interval between

them only moderately wide. Thorax long and narrow, much narrowed in front, densely

and coarsely punctured, with an abbreviate channel in front of the base in the middle.

Elytra convex and narrow, deeply sulcate. Middle tibie dilated and flattened, their

posterior face clothed with long, dense, pallid hair. Hind femora greatly incrassate.

Only one example of this extraordinary insect was obtained by Mr. Smith. Gers-

tacker described the species from a unique example, also of the male sex.

As I cannot at all determine from the description to what species this is allied, I

place it at the end of this division, though the antenne are said to be inserted close to

the eyes.

I do not find anything agreeing with Gerstacker’s description among our specimens ;

it is probable, however, that A. chalceum is allied to A. oscillator.

Long. 2 millim.

Hab. Mexico, Frontera in Tabasco (//ége).

Rostrum as long as the head and thorax, curved, cylindrical, polished; head short ;

eyes convex, moderately widely separated, the space between them obsoletely trisulcate ;

antennee inserted close to the base. Thorax rather short, very coarsely punctate, with

a short fovea in front of the base. Elytra rather deeply sulcate, the sulci very coarsely

punctate and bearing some very minute white sete, the interstices shining, subconvex.

Under surface with white pubescence outside the middle coxe and along the sides of

the metasternum ; intermediate coxe moderately distant. Legs slender.

This species would be naturally placed next A. guatemalenum ; but it has the tibie

pallid, though only obscurely so, the antennze inserted close to the base of the rostrum,

and the thorax densely and coarsely punctured, so that it is unmistakably distinct from

its ally placed in the first division. The fact that the sete are placed in the grooves

of the elytra and not on the interstices distinguishes it from most other species, but

unfortunately they are very minute and are detected only by careful observation. Four

specimens were obtained, of uncertain sex.

39. Apion acarinum, sp. n.

Minutum, obesulum, nigrum, peropacum, tenuiter griseo-pubescens ; antennis pedibusque rufo-testaceis ; rostro

sulcatis.

Long. 14 millim.

Hab. GuateMALA, Senahu (Champion).

Rostrum small, smooth in front of the insertion of the antenne, which is quite basal ;

eyes convex, the space between them punctured and dull; antenne yellow, short, about

as long as the rostrum, the second joint globular. Thorax strongly transverse,

narrowed in front, its punctuation indistinct and rather distant, but not fine. Elytra

somewhat deeply sulcate, the interstices rather narrow, not quite flat. Middle coxe

moderately separated.

This tiny Apion is of somewhat unusual proportions, the hinder portion of the body

being large and obese in comparison with the small anterior parts. Mr. Champion

procured a good series of examples, but I cannot find any sexual characters to distin-

guish them. ‘Lhe colour of the rostrum appears to be variable, passing from nearly

black to yellow; but most of the specimens are intermediate in this respect, so that

I do not think it can be a mark of the sexes.

Hab. GuateMata, San Gerdénimo (Champion).

Rostrum dissimilar in the sexes, slender, not so long as the head and thorax—in the

female very slender, polished, in the male broader and setose; eyes not large, but

quite convex, separated by a very wide interval; antenne inserted almost beneath the

front of the eyes, at the base infuscate-yellow. Thorax conical, without punctuation,

but with a very distinct setosity. Elytra moderately deeply sulcate, the interstices not

much broader than the grooves, rather densely setose. Legs pale yellow ; tarsi dusky

red, rather broad; middle coxe slightly separated.

Ten examples were procured of this species; they are precisely alike, except in the

sexual distinctions.

Hab. Panama, David (Champion).

Rostrum almost as long as the head and thorax, dissimilar in the sexes—in the female

with a rather large broad basal portion, and a slender cylindrical polished anterior part,

while in the male the anterior part is not so slender, is not abruptly distinguished

from the basal portion, and is not polished but feebly sculptured and setose, except

at the tip; the eyes are rather small but convex, the antenne inserted some distance

in front of them; the space between the eyes is broad. The thorax is rather broad

and short, greatly narrowed in front, not visibly punctured, but with a well-marked

depressed squamosity. Elytra stout, rounded and convex, with well-marked rather

deep grooves, and a pallid squamosity distributed irregularly so as to give a spotted

appearance, the spots being most distinct around the discoidal area. The legs are

rather stout, pale yellow, with the tarsi reddish; the coxe and trochanters are red ;

the middie coxe are not widely separated.

Four examples were obtained of this species; it is not likely to be confounded with

any other owing to the spotted arrangement of the squamosity.

66 RHYNCHOPHORA.

Of this species three examples of the male sex were obtained. ‘The rostrum is rather

long and stout, more slender at the tip, which is bare, the rest being sculptured and

setose, the basal part is thick; the antenne are inserted very near the eyes, but still a

little in front of them, they are yellow with the club darker; the eyes are widely

separated and very convex. The thorax is elongate, much narrowed towards the front,

and densely covered with a pale squamosity. The elytra are not very broad; they

bear a good deal of squamosity, which on the first and third interstices is denser than

elsewhere. The legs are stout, pale yellow, the tarsi fuscescent; the coxe and tro-

chanters are red; the middle cox are slightly separated.

The female will probably be found to possess a highly polished cylindrical rostrum,

with a very short broad basal portion.

43. Apion matricum, sp. n.

Breve, latum, tenuiter setosum, nigrum, subopacum, pedibus rufis ; rostro mediocri, polito, summo basi crassiore ;

prothorace conico, dense fortiterque punctato ; elytris profunde sulcatis.

Long. 2 millim.

Hab. Panama, San Feliz (Champion).

Rostrum about as long as the head and thorax, dissimilar in the sexes—in the female

slender and very polished, with the short part behind the insertion of the antenne

abruptly thicker ; in the male less polished, and not so slender, the basal portion being

not abruptly distinguished from the anterior portion; eyes large, convex, separated

by an unusually broad space, the insertion of the antenne at a distance in front of

the eyes rather less than the ocular interval, Thorax broad at the base, greatly

narrowed in front, very coarsely punctured, with a channel along the middle behind.

Elytra broad, with deep and distinct grooves in which the large punctures are very

distinct. Legs dusky red, with the tarsi dark; all the coxe and the hind trochanters

black, the anterior trochanters fuscescent; the middle coxe widely separated. One pair.

Not at all closely allied to any other species of the genus. A. sancti-felicis is the —

most similar, but has no incrassation of the base of the rostrum, and the head and

eyes in it are very much narrower.

Hab. Pyyama, Tolé (Champion).

Of this species only two specimens have been received, and it is probable that both

are females; the rostrum is very slender, elongate, and quite polished, with a very

separated ; the antenne are inserted almost beneath the front of the eyes, and have an

elongate basal joint and also a long, slender, pointed club. The thorax is large, broad

at the base, regularly and considerably narrowed towards the front, with very minute,

pubescence and obsolete punctuation. The elytra have remarkably definite, deep

grooves, with distinct puncturesin them. The middle coxeare only slightly separated.

The legs are stout, with broad tarsi.

45. Apion calcaratipes, sp.n. (A. calearatum, Tab. I. fig. 20, ¢ -)

Obesum, nigrum, setis griseis depressis vestitum, capite elytrisque pone scutellum densius albido-vestitis,

sat profunde, minus late, sulcatis.

Long. 23 millim.

Hab. GUATEMALA, Panajachel (Champion).

Rostrum about as long as the head and thorax—in the female slender, cylindrical,

smooth and shining, but between the eyes and the insertion of the antenne much

thicker and clothed with scales; in the male but little, if at all, shorter, and with

the thick basal portion becoming gradually attenuate, so that only the apical half is

slender, shining, and free from scales; the eyes are very large and prominent, and the

space between them is broad; the antenne are yellow, and are inserted just in front of

the eyes on the under surface. The thorax is broad at the base, but much narrowed

in front, its punctuation is indistinct, the depressed pallid sete being on the contrary

evident. The elytra are rather broad and convex, and are thickly clothed with

griseous-white sete which obscure their sculpture; there is a patch of white scales

immediately behind the scutellum. The under surface is rather densely clothed with

white scales, which are very conspicuous under the eyes. The middle coxe are a little

separated. Male with a small mucro on each of the middle and hind tibie at the

inner margin of the apex. Five specimens.

separated by a rather narrow space; antenne inserted near to the eyes, but at a rather

greater distance than the width of the ocular interval. Thorax small, subconical, very

polished, and quite free from punctuation. Elytra inflated, shining, without grooves,

but with series of distinct punctures. Legs slender. Metasternum short. Middle

cox nearly, if not quite, contiguous.

68 RHYNCHOPHORA.

Only one specimen has been received. It is one of the most distinct species of the

genus: the highly polished surface of the rostrum and thorax, the absence of grooves

on the elytra, the form and colour, being each of them peculiar.

47, Apion subrufum, sp. n.

Gracile, nitidum, subnudum, nigrum, antennis, pedibus elytrisque sordide rufis, prothorace subsnescente, parce

punctato ; rostro mediocri, polito; elytris subtiliter sulcatis.

Long. 1? millim.

Hab. Guatemaua, La Tinta in Vera Paz (Champion).

Rostrum rather longer than the head and thorax, polished, cylindrical; antenne

inserted about as far in front of the base as the width of the ocular interval, which is

rather small, and bears a few coarse but subobsolete punctures; the eyes convex. ‘The

thorax is slender, much narrowed to the front, sparingly punctured, without channel.

Elytra obscure red in colour, shining, with rather fine grooves, and very flat, broad

interstices. Middle coxee not broadly separated. Sides of the breast with a fine line

of white setosity. Two examples.

The peculiar reddish colour of the elytra is somewhat similar to that of A. subauratum

and A. teapense; the former has a quite different rostrum and a peculiar setosity, and

the latter remarkably deep definite grooves on the elytra, while in A. subrufum the sulci

are rather fine.

48. Apion hastifer, sp. n.

Gracile, nigrum, nitidum, tenuissime pubescens, antennis pedibusque flavis, maris rostro anterius flavescente ;

oculis prominulis, inter sese distantibus; rostro gracili, parte anteriore tenui, subrecto, parte basali crassiore.

Long. 2 millim.

Hab. Panama, Bugaba, David, San Feliz, Tolé (Champion).

Antenne inserted about as far in front of the eyes as the width of the ocular

interval, which is broad, the eyes being large and convex; the anterior part of the

rostrum is slender and attenuate in front, in the male yellow, in the female black.

Thorax slender, a little dilated in the middle so as to appear broadly but faintly

constricted in front and behind, feebly punctate. Elytra rather finely sulcate, the

interstices not convex. J.egs moderately long, yellow, the tarsi fuscescent, at any rate

towards the extremity; middle coxe moderately distant. Male with a small mucro

on the inner margin of the middle tibie at the extremity.

We have received eight examples that I refer to A. hastifer; I am not sure, however

but what they may belong to two or three species very closely allied, with considerable

sexual differences in the case of each ; they vary a little in size, colour, and punctuation,

and in the length of the legs. As this small number of examples are from four

different localities, I can come to no positive opinion about them, but the following is

clearly distinct.

This is distinguished from A. hastifer by its more delicate build, longer legs and

rostrum, and the narrower head and eyes; by this latter character it is easy to

separate the two when they are placed side by side. We have received four examples

of A. poeticum.

Panama, David (Champion).

Rostrum of the male scarcely so long as the head and thorax, rather stout, punctate,

but shining, of the female considerably longer, more slender, polished; eyes convex,

somewhat widely separated; antenne black, inserted a little farther in front of the

eyes than the width of the interocular space. Thorax rather short, moderately

broad, a good deal narrowed in front, and slightly constricted, blackish in colour, more

or less feebly eenescent, shining, very sparingly punctate. Elytra dark red, smooth and

shining, with series of faint distant punctures, which, however, are variable in their

size; there is a marginal deeply impressed stria, and at the apex of each wing-case two

or three deep impressions with convex interstices. Underside of the breast and

abdomen red, the former with white hairs at the sides; middle coxe widely separated.

Legs variable in colour—usually red, but in some specimens the front femora are infus-

cate in the middle; sometimes they are all so much infuscate as to be nearly black.

The male has a well-marked mucro at the apices of the middle and hind tibie.

We have received a fair series of this species, but made up from very scattered

localities. If all belong to one species then it is a very variable one; the colour of

the legs, as already stated, varies from clear red to nearly black; and the head, thorax,

and rostrum are sometimes rufescent to a greater or less extent. But the most striking

variation is in the sculpture of the elytra: the serial punctures are sometimes scarcely

to be detected, while in other cases they are well marked and quite conspicuous, and in

some individuals those near the suture are deep and connected together so as to form

there two or even three strie.

the head and thorax, in the female much longer; eyes large and prominent, the space

between them moderately broad, bearing three short, broad grooves separated by fine

carine:; antenne black, inserted about as far in front of the eyes as the width of the

space between them. Thorax conical, much narrowed in front, densely and rather

coarsely punctate, with a short deep channel in front of the scutellum. Elytra broad

and short, much broader than the thorax, with deep distinct grooves and flat interstices.

Legs red, the coxe and trochanters black. Under surface sparingly clothed with

white pubescence, which is dense at the sides of the breast, on the front of the anterior

coxee, and at the sides of the rostral scrobes. Male with a short mucro at the apex

of each of the middle and hind tibie.

This is closely allied to A. chiriquense, but is of less elongate form, and the hind

femora are clear yellow-red in colour; these two characters seem quite sufficient to

distinguish the species from A. chiriquense. The upper surface bears a few scattered

hairs, and there is a condensation of them at the base of the third interstice of the

elytra so as to form a white spot on each side; and there is also a condensation of

white sete at the sides of the breast beneath. The sexual difference in the rostrum is

not great, but that of the female is a little longer and more slender.

middle of the femora, the knees, and the tibie before the extremity being of this

colour. Middle coxe slightly separated. Under surface without any distinct pubes-

cence; cox and trochanters black.

The variegate colour of the legs will be one of the best clues to the identification of

this obscure insect. Only three examples have been received; the one from Northern

Sonora does not differ in any important particular, so far as I can discover, from the

two found on the Volcan de Chiriqui. Perhaps all are of the male sex.

one-third of the length, and not flavescent ; antenne inserted about as far in front of

the base as the width of the interocular space, this being only moderately broad and very

little sculptured ; eyes rather large and prominent. ‘Thorax regularly and considerably

narrowed from the base to the front, almost impunctate, sparingly clothed with fine

golden depressed setosity. Elytra with narrow, moderately deep grooves, in which

punctures can scarcely be detected ; the interstices broad, with a very distinct golden-

grey setosity. Legs clear yellow, with the cox and trochanters of the same colour.

Under surface clothed with a pallid setosity. Middle cox not widely separated.

Intermediate tibiz of the male armed with a very minute mucro at the apex of the

inner margin.

Mr. Champion procured a good series of this species; but, unfortunately, most of

the specimens are in a bad state of preservation. ‘The peculiar colour and the golden

setosity lead to the identification of this species without difficulty.

66. Apion teapense, sp. n.

Sat gracile, ovale, nigrum, subopacum, fere nudum, elytris rufo-obscuris, prothorace subanescente, antennis

pedibusque rufis ; prothorace conico-cylindrico, parce punctato; elytris argute sulcatis, interstitiis latis,

planis.

Long. 2} millim.

Hab. Mexico, Teapa in February (1. H. Smith).

Rostrum somewhat longer than the head and thorax, rather slender, cylindrical, a little

curved, feebly punctate, shining ; head short and broad ; eyes convex, the space between

them moderately broad, deeply biseriately punctate; antenne dull red, inserted quite

as far in front of the eyes as the width of the interocular space. Thorax consider-

ably narrowed in front, sparingly, moderately coarsely punctate, with a small fovea in

the middle in front of the base. Elytra with remarkably sharply-marked grooves and

broad flat interstices. Legs obscure red; coxe and trochanters ‘black. Middle coxe

but little separated

This is another species that is easy to recognize, the peculiar colour, the absence of

setosity, and the sharply-marked sulcation of the elytra being characteristic. Only

two examples have been found, and it is probable that both are of the female sex.

APION.

67. Apion sancti-felicis, sp. n. (Tab. II. fig. 19.)

Breve, nigrum, subopacum, tenuiter setosum, antennarum basi pedibusque fusco-testaceis; rostro mediocri,

cylindrico, curvato, sublevigato ; prothorace conico, fortiter punctato; elytris profunde sulcatis.

Long. 14 millim.

Hab. Panama, San Feliz (Champion).

Rostrum about as long as the head and thorax, slender, cylindrical, curvate, without

sculpture; head short and broad; eyes convex, the space between them somewhat

narrow; antenne inserted at a rather greater distance in front of the eyes than

the width of the ocular interval, slender, the four or five basal joints dusky red.

Thorax rather broad, much narrowed towards the front, densely rugose-punctate, with a

short channel at the base in the middle. Elytra short and broad, subglobular; the

sulci moderately deep, not broad; the interstices not quite flat, finely and scantily

setose. Legs rather slender; the front pair sordid testaceous, with the tarsi and the

upper margin of the femora darker; the intermediate and posterior pairs still darker,

with only the upper part of the tibize testaceous.

Only one example was obtained of this insect. Though an obscure species and

without any salient characters, it is by no means closely allied to any other.

68. Apion pedestre, sp. n.

Robustum, nigrum, subopacum, setosum, antennarum basi pedibusque ex parte rufo-sordidis ; prothorace

magno, dense punctato.

Long. 23-3 millim.

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

Rostrum very different in the sexes—in the female slender and quite polished,

cylindrical, but little curved, rather longer than the head and thorax; in the male

shorter, stouter, and sculptured, sulcate at the sides; eyes rather large, a little convex,

not separated by a broad space; antenne red at the base, inserted somewhat farther

from the eyes than the width of the ocular interval. Thorax large at the base, much

narrowed in front, a little convex, very densely punctured, setose, with a distinct

channel at the base in the middle. Elytra rather deeply, but not broadly, sulcate.

Legs stout ; femora, especially the hind pair, in the male somewhat incrassate ; cox#

and trochanters black; front femora and tibie red, the former infuscate above, the

latter in the middle ; middle femora dull red, broadly blackish at the tip, the tibie dark,

marked with red near the base; hind legs with the red marks still more diminished.

Middle coxze very widely separated, the junction of the meso- and metasterna forming a

raised line.

Five examples were found of this species, which should be identified without

difficulty.

69. Apion rugirostre, sp. n.

Gracile, nigrum, supra subsenescens, tenuiter setosum, antennarum basi pedibusque flavis ; rostro brevi, densis-

sime subtiliter rugoso; prothorace subcylindrico, obsolete punctato.

Long. 12 millim.

Hab. Mexico, Acaguizotla in October, Atoyac in May, Teapa in January (ZZ. #7.

Smith); GuateMALA, Aceituno, Zapote, San Gerdénimo (Champion); Panama, Volcan

de Chiriqui, Taboga Island (Champion).

Head elongate and narrow; eyes but little prominent, widely separated; rostrum

but little longer than the head, thick, very densely and finely sculptured and minutely

setose ; antenne inserted slightly behind the middle. Thorax slender, straight at the

sides, indistinctly punctured. Elytra finely and moderately deeply sulcate. Under

surface densely punctured ; the setosity very minute, scarcely so distinct as on the upper

surface. Middle coxe contiguous. Legs pale yellow, the trochanters of the same

colour; the middle and hind coxe infuscate. Hind margin of the first ventral segment

slightly incrassate on each side of the middle; the suture between it and the second

segment angulate or produced a little forwards at the spot where the incrassation is

interrupted.

This little Apton may be identified by the short, densely sculptured rostrum, the

contiguous middle cox, and the peculiar abdominal structure. I have not detected

any certain means of distinguishing the sexes ; some examples, however, seem to have

the ventral peculiarities less developed than in others, and it is possible these may be

of the female sex. We have received fourteen examples of 4. rugirostre.

70. Apion auctum, sp. n.

Gracile, nigrum, supra subsnescens, tenuiter setosum, fere opacum, antennarum basi pedibusque flavis; rostro

parum elongato, densissime subtiliter rugoso ; prothorace conico-cylindrico, crebre sat fortiter punctato.

Long. 2 millim.

Hab. Mexico, Orizaba in December (f. D. Godman & H. H. Smith), Cuernavaca in

June, Chilpancingo in July (. A. Smith); Guaremaua, Aceituno (Champion).

This insect is extremely similar to 4. rugirostre, but it is a little larger, and has

the rostrum slightly longer, especially in the female ; the trochanters are dark in colour ;

and the suture between the first and second ventral segments is simple.

We have received about twelve examples of this species from Mexico, but only one

from Guatemala.

71. Apion nodicorne, sp.n. (Tab. III. figg. 18, ¢; 18a, profile of head, ¢.)

Angustum, nigrum, griseo-setosum, ad suturam pone scutellum albido-signatum, antennis pedibusque rufo-testa-

ceis; rostro sat elongato, cylindrico, gracili, anterius attenuato, ad basin incrassato; antennarum articulis

duobus basalibus brevibus, nodosis.

Long. 2-27 millim.

APION. 79.

Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith); Guatemata, San Gerénimo

(Champion); Panama, Bugaba (Champion).

Rostrum slender, quite as long as the head and thorax, in front of the insertion of the

antenne cylindrical, behind this thicker, similar in length in the two sexes—in the female

setose only at the base, the apical portion being polished, in the male setose as far as

the apex; eyes large, convex, not widely separated; antenne inserted about as far as

the length of the eye in front of the eye and under a minute lateral prominence of the

rostrum, yellow, the first and second joints almost equal, stout. Thorax rather large,

curved at the sides and greatly narrowed in front, densely punctate, and with an ex-

tremely fine channel extending the greater part of its length. Elytra somewhat densely

clothed with griseous setosity, and with a very conspicuous white patch immediately

behind the scutellum, rather deeply sulcate. Legs bright yellow; apices of the tarsi

fuscescent; coxee and trochanters black. Under surface clothed with white setosity ;

middle coxee rather widely separated.

Mr. Champion procured a fine series of this distinct species at San Gerdénimo; the

specimens do not exhibit any variation. Mexico and Panama have each yielded only

one individual.

72. Apion pacificum, sp. n.

Sat angustum, nigrum, subopacum, breviter griseo-setosum, antennis pedibusque cum coxis rufis; rostro brevi,

maris ad apicem rufo; prothorace parvo, conico-cylindrico, obsolete punctato; elytris convexis, sat pro-

funde sulcatis, interstitiis planis.

Long. 2; millim.

Hab. GuatTemata, near the city (Champion).

Rostrum short and stout, curvate, a little attenuate towards the apex, finely sculptured

and feebly pubescent, dull; eyes moderately large, but not prominent, separated by a

rather narrow space, which is destitute of any evident sculpture ; antenne inserted a

little behind the middle. Thorax slender, a good deal narrowed towards the front, only

obsoletely punctured and without channel, sparingly but distinctly clothed with white

setee. Elytra almost oval in outline, rather deeply and moderately widely sulcate,

the interstices broad, flat, finely, moderately closely pubescent. Legs reddish-yellow ;

tarsi infuscate ; middle coxe not widely separated.

A good series was obtained of this obscure insect; the specimens exhibit very little

variation, and the sexes are not very different except in the colour of the rostrum.

73. Apion ferrugineum, sp. n.

Ovale, ferrugineum, fere nudum, sat nitidum; rostro mediocri; elytris anguste profunde sulcatis, interstitiis

subconvexis.

Rostrum rather slender, punctulate, a little shining, in the male quite as long as the

80 RHYNCHOPHORA.

head and thorax, in the female a little longer ; eyes small, moderately widely separated ;

antenne inserted behind the middle, nearly as far from the eyes as the width of the

head and eyes. Thorax small, short, much narrowed in front, sparingly and obsoletely

punctured, without channel. Elytra a good deal narrowed towards the base, deeply

but rather narrowly sulcate, the interstices moderately broad, convex. Legs slender ;

tibize with a very slight infuscation in the middle ; intermediate coxe nearly contiguous.

Three examples.

74. Apion laterale, sp. n.

Robustum, nigrum, supra e«nescens, setosum, corpore ad latera albido-vestitum, antennis pedibusque pallide

flavis ; prothorace lato, dense punctato.

Long. 23 millim.

Hab. Mexico, Ventanas in Durango (fége); GUATEMALA, near the city (Champion).

Rostrum short, in the male about as long as the thorax, in the female a little longer,

rather stout, slightly attenuate towards the tip, feebly punctate, dull, finely setose ; eyes

somewhat large, but little convex, separated by a moderately wide space; antenne

yellow, short, inserted as far in front of the eyes as the width of the ocular interval.

Thorax broad and short, greatly narrowed in front, densely but rather indistinctly

punctate, finely setose, with a channel at the base in the middle. Elytra finely sulcate,

rather closely pubescent. Under surface densely clothed with white setosity at the

sides. Legs short, pale yellow; coxe and trochanters black ; middle coxe somewhat

widely separated.

75. Apion longicolle, sp. n.

Angustum, nigerrimum, nitidum, antennis tibiisque testaceis vel fusco-testaceis ; rostro brevi, crasso ; prothorace

elongato, cylindrico ; elytris striatis, singulo ad basin albido-cristato, ante apicem impresso.

Long. 13-23 millim.

Hab. GUatEMALA, Paso Antonio (Champion).

Rostrum not curved, shorter than the thorax, thick, feebly setose; eyes rather large,

convex, somewhat widely separated, the space between them strigose ; antenne inserted

just behind the middle. ‘Thorax elongate and slender, the sides rather irregular in

outline, owing to a very feeble transverse depression in front of the middle and a still

more obscure one behind it; impunctate, bearing a very few, small, white hairs. Elytra

narrow, finely striate ; each at the base with a small patch formed by some white hairs,

and just before the extremity with a depression in which there are some white hairs.

Femora nearly or quite black ; tibize either sordid yellow or strongly infuscate ; middle

cox separated by a slender lamina.

This insect is allied to A. constricticolle, and its location in another section, owing

to the colour of the legs, is unsatisfactory, especially as this character appears to be

variable ; as species the two insects are, however, quite distinct.

Five specimens.

APION. 81

76. Apion terminale, sp. n.

Angustum, nigerrimum, nitidum, tenuiter albido-setosum, antennis pedibusque testaceis ; rostro brevi, recto ;

elytris striatis, ante apicem impressis, apice subtumidulo.

Long. 2 millim.

Hab. Mexico, Amula in Guerrero in August (H. H. Smith).

Closely allied to A. longicolle, but with the femora as well as the tibie and tarsi

yellow; the thorax shorter, and the upper surface bearing a scanty scattered setosity,

the unusual formation of the apices of the elytra more pronounced, and the sides of the

breast quite covered with white setosity.

One example.

77. Apion inflatipenne, sp.n. (Tab. III. fig. 19.)

Breve, nigrum, nudum; elytris viridi-cyaneis, latissimis, ad basin quasi deplanatis, subtiliter sulcatis ; pedibus

nigris, femoribus in medio rufis.

Long. 27-34 millim.

Hab. Guatemaua, El Reposo (Champion).

Rostrum rather stout, cylindrical, curved, longer than the head and thorax, punctate,

shining; eyes somewhat convex ; antenne inserted a little behind the middle of the

rostrum. Thorax rather short, greatly narrowed in front, somewhat finely but not

densely punctate, with a short, deep, foveiform channel in front of the base in the

middle. Elytra remarkably broad, appearing almost as if inflated, but somewhat

deplanate in front, with rather fine, not deep sulci and very broad, flat interstices,

somewhat dull. Under surface without any setosity. Middle coxe well separated ;

hind legs black, with the larger part of the femora red.

Two specimens.

78. Apion latipenne, sp. n.

Breve, nigrum, nitidum ; elytris viridi-cyaneis, latis, convexis, profunde minus late sulcatis ; prothorace conico,

parce punctato; femoribus late rufis.

Long. 24 millim.

Hab. Panama, Pefta Blanca (Champion).

Rostrum rather short, cylindrical, shining, sparingly punctate, sulcate above on each

side; antenne inserted about one-third of the length from the base; eyes but little

prominent. Thorax somewhat small, greatly narrowed in front, rather finely and

sparingly punctured. Elytra very broad and short, very convex, much narrowed in

front, with moderately deep and broad grooves. Legs not very stout; middle coxe

but little separated ; femora red, except at the tips. One specimen.

Though similar in appearance to 4. inflatipenne, this is, no doubt, distinct from that

species, as it differs in numerous slight particulars, among others in having a very fine,

minute, and scanty setosity on the thorax and elytra.

Long. 23 millim.

Hab. Guaremata, near the city (Champion); Panama, Volcan de Chiriqui (Champion).

Rostrum quite as long as the head and thorax, stout, rugose, with a channel on each

side of the upper surface extending from the front of the eye to near the extremity ;

eyes very convex, the interval between them narrow, deeply bisulcate ; antenne inserted

about one-fifth of the length of the rostrum in front of the eyes. Thorax large, broad

at the base, elongate, greatly narrowed in front, and broadly constricted behind the

anterior margin, very coarsely and very densely punctured, with a fine channel at the

base in the middle. Elytra moderately deeply sulcate; interstices rather broad, a little

concave. Legs black, with the basal part of the femora broadly bright red. Coxe

bearing a good deal of white setosity, the middle pair rather widely separated.

Three specimens were obtained of this species; it is well distinguished from all our

others.

80. Apion gibbosum, sp.n. (Tab. IIL. figg. 21; 21 a, profile.)

Latum, valde convexum, opacum, rufo-brunneum, setosum, elytrorum disco griseo-signate ; pedibus flavis ; rostro

crasso, apicem versus attenuato.

Long. 27 millim.

Hab. Panama, Tolé (Champion).

Rostrum subulate, longer than the thorax, the basal portion thick, dull, setose, the

apex black, bare for a short distance only in the male, in the female for a longer

distance; antenne fuscous; eyes convex, very widely separated, the space between

them only finely sculptured like the rest of the surface. Thorax large, greatly narrowed

in front, and a little constricted behind the anterior margin, dull, obscurely punctate,

setose, with a short fine channel in front of the base in the middle. Llytra short and

broad, with the disc very convex, the posterior part abruptly declivous, setose, the most

elevated part surrounded by a griseous mark, deeply sulcate, the interstices broad, flat,

finely rugose. Legs thick, pale dull yellow; coxe and trochanters fuscous, the sides

with much pale squamosity ; middle coxe moderately separated.

Six specimens were obtained of this remarkable species; and we have received an

example from Honduras which may be a variety of it, the colour being paler and the

mark on the disc of the elytra different.

81. Apion lentum, sp. n. (Tab. III. fig. 22.)

Breve, convexum, parce setosum, nigrum, supra rufescens, elytrorum sutura nigricante, prothorace fere

impunctato, elytris anguste sulcatis.

Long. 14 millim.

Hab. GUATEMALA (Champion).

APION. 83

Of remarkably short form and peculiar coloration, the upper surface bearing a scanty,

but rather elongate, white setosity. The rostrum is red and as long as the head and

thorax, somewhat slender, shining, sparingly punctate; the eyes are small but slightly

convex, placed near to the thorax; antenne inserted as near to the eyes as the width

of the ocular interval, which is not great. Thorax short and broad, much narrowed in

front, without distinct punctuation, but with a conspicuous depressed white setosity.

Elytra pale testaceous-red, with the suture black, with rather fine moderately deep

grooves and broad interstices, which have a slight convexity. Legs, including the tro-

chanters, yellow ; metasternum very short; middle coxe slightly separated.

We have no other species at all closely allied to this one.

Three examples,

82. Apion amenum, sp. n.

Nigrum, elytris viridi-cyaneis, femoribus rufis apicibus nigris; rostro gracili, anterius polito, oculis prominulis ;

prothorace parce punctato, canaliculato ; elytris sat late profundeque sulcatis, interstitiis planis.

Long. 23-23 millim.

Hab. Panama, Volcan de Chiriqui (Champion).

Rostrum of the female longer than the head and thorax, the anterior part very polished,

quite slender, the basal part considerably thicker but still slender; eyes convex, not

widely separated ; antennze inserted about as far in front of the eyes as the width cf the

head and eyes, the two basal joints stout, piceous; in the male the rostrum is less

elongate, and its anterior portion not so slender and polished. ‘Thorax moderately

large, a good deal narrowed in front, with the anterior margin somewhat elevated ;

sparingly and not coarsely punctured, with an elongate channel on the middle. Elytra

with deep grooves, which are very distinctly punctate, and broad plane interstices.

Legs rather long; femora bright red, except at the tip; front coxe with white

pubescence in front; there is a similar setosity outside the middle coxe and along the

sides of the metasternum ; middle cox moderately distant.

This insect 1s perhaps nearer to 4. nodicorne than to any other species, although the

two are so different in colour and appearance.

A single pair.

83. Apion grallarium, sp.n. (Tab. II. fig. 23.)

angulo externo singulo quasi nodoso-dilatato.

Long. absque rostro 3 millim.

Hab. Guatemata, San Gerénimo (Champion).

This curious Apion is like no other species of the genus; it is of slender form, with

long, slender, pallid legs; of a dull brownish colour, bearing numerous long, depressed,

white sete. The rostrum is rather slender, narrower in front, nearly straight; the

head is elongate; the eyes remarkably long, the antenne inserted a little behind the

middle. The thorax is slender, narrowed in front. The elytra are elongate, extremely

finely striated; at the apex each is slightly swollen so as to form a sort of lateral

prominence, and in each prominence there is placed a very deep depression or pocket.

The front coxe are yellow, the others red, all the trochanters being of this latter

colour. ‘The breast is remarkably prominent, the first ventral segment being subper-

pendicular in its direction.

84. Apion samson, sp.n. (ab. III. fig. 23, 3.)

Grande, nigrum, opacum, elytris cyaneis ; femoribus rufis, apice nigro.

Long. 5-53 millim.

Hab. British Honpuras, Rio Hondo (Blancaneaux); Panama, near the city

(Champion).

Rostrum stout, rather long, quite as long as the head and thorax, densely punctate,

in the female slightly longer and more slender than in the male; antenne inserted just

behind the middle; eyes moderately large, a little convex. Thorax much narrower

than the elytra, nearly straight at the sides behind, but a good deal narrowed in front,

very densely and coarsely punctate, with a deep abbreviate channel in front of the base

in the middle. Elytra rather elongate, blue, dull, somewhat deeply sulcate, the inter-

stices broad. Legs thick, the tarsi broad, the claws stout. Under surface destitute of

squamosity ; middle coxe only slightly separated; metasternum with a deep fovea;

the coxe and trochanters intense black; the femora bright red nearly to the extremity ;

the rest with the tibie and tarsi deep black.

Mr. Champion obtained a large number of examples of this remarkable species ; they

do not exhibit any variation. ‘The four specimens from British Honduras differ very

slightly, however, the antenne being inserted a little farther back. The Panama

examples were beaten from the seed-pods of a leguminous tree.

85. Apion latipes, sp.n. (Tab. III. fig. 24.)

Hab. Panama, Volcan de Chiriqui (Champion).

Rostrum scarcely so long as the head and thorax, stout, punctate but not rugose, dull;

eyes slightly prominent; antenne inserted just behind the middle of the rostrum.

Thorax rather long, much narrowed in front, the surface of a silky opacity, finely and

sparingly punctate. Elytra laterally subcompressed, of a greenish-blue colour, finely

sulcate, with broad flat interstices, rather shining. Legs stout, black; femora bright

red, except at the tip. Under surface dull; middle coxe only slightly separated.

One specimen only.

Long. 3 millim.

Hab. Mexico, Atoyac in April (H. H. Smith), Jalapa (Hoge).

Rostrum rather stout, nearly as long as the head and thorax, punctulate and finely

setose, except at the tip; eyes elongate, a little prominent, separated by a somewhat

narrow interval; antenne inserted about the middle of the rostrum, yellow, darker

towards the extremity. Thorax large, its base forming a sort of margin to the elytra, to

which it is very closely applied, and extending outwards so as to embrace the shoulders,

much narrowed in front, very coarsely punctate, finely setose, with a channel at the base in

the middle. Elytra rather broadly sulcate, with flat interstices and delicate pubescence.

Legs stout, reddish-yellow ; coxe, trochanters, knees, tips of the tibie, and the tarsi

black ; sides of the body densely clothed with white setosity ; middle coxee moderately

separated.

Two specimens have been received of this distinct species.

HETERAPION, gen. nov.

Tarsi quasi triarticulati, articulo tertio a secundo fere occulto. Femora inflata.

This genus agrees with Apion in its characters except as to the points mentioned

above. The tarsi have a knotted appearance: the first joint is slender at the base,

broader and convex at the apex; the second joint is slender at its articulation with the

basal one, and at its apex it so closely embraces the third joint that the line of demarca-

tion between them can scarcely be detected, but when perceived it is found that only

the bilobed apex of the third joint remains visible; the claw-joint is slender, the claws

small and lobed at the base. ‘The trochanters are elongate, and are interposed between

the coxe and the femora as in Apion; the femora are slender at the point of articula-

tion with the trochanter, but are inflated in the middle.

1. Heterapion femoratum, sp. n. (Tab. III. fige. 26; 26 a, tarsus.)

Long. 27 millim.

Hab. Mexico, Atoyac in Vera Cruz in April (7. H. Smith).

Rostrum elongate, cylindrical, slightly curved, shining, sparingly punctate; eyes

elongate, rather convex, separated by a narrow space which is obsoletely bicarinate ;

antenne inserted at about one-fifth of the length of the rostrum in front of the eyes,

black, the club solid. Thorax elongate, without punctuation, with a silky opacity of

the surface, and a short channel in the middle in front of the base. Elytra not sulcate,

but striate, the strie bearing rather large but obsolete distant punctures, the interstices

feebly convex. Middle cox not widely separated.

86 RHYNCHOPHORA.

Only one example was found of this interesting insect ; it shares the very delicate,

upright pubescence with the next species, but this character is foreign to the species of

Apion found in our region.

2. Heterapion infirme, sp. n.

Nigrum, pube erecta vestitum, femoribus flavis; prothorace brevi, parce punctato.

Long. 13 millim.

Hab. GuateMaLa, Zapote (Champion).

Rostrum as long as the head and thorax, shining, punctulate; eyes separated by a

narrow interval, which is punctate like the thorax. ‘Thorax short, a little narrowed

in front, distinctly punctate, with a small foveiform channel in the middle in front of

the base. Elytra striate, with convex interstices, which are indefinitely sculptured, the

upright pubescence rather long and distinct.

Except in the short thorax and small stature, this species is closely allied to H. femo-

ratum. The two examples found are quite similar to one another.

Subfam. THECESTERNINA.

I propose to separate for the present the genus Thecesternus as a separate subfamily.

It is placed by Lacordaire as a group of the tribe Byrsopsides, but Lacordaire’s tribe

must be wholly dissolved, as it is composed of forms having but little relation with one

another. I therefore separate Thecesternus and place it in the position given it by

Leconte and Horn.

The true position of Thecesternus is, however, certainly not here; it appears to have

some affinities with the Australian Huomus—a genus of Amycterides—and with the

Cryptorhynchideous division of Curculionide. But a dissection of the parts of the

mouth and prosternum is necessary before any trustworthy opinion as to the position

of the genus can be formed, Lacordaire’s examination of these points being inadequate.

This species formerly occurred under the dried dung of the bison, but appears to be

now very rare. It must be variable, as Leconte separated it into six species at one

time. Herr Hége procured only one pair; these agree with an individual from the

United States kindly forwarded to me by Dr. Horn, the insect being excessively rare in

European collections.

Subfam. OTIORHY NCHINE.

Otiorhynchide, Leconte and Horn, Rhynchophora of N. America, p. 13.

Brachyderides, Otiorhynchides (part.), Lacordaire.

This subfamily is defined in a satisfactory manner by the existenre of a scar on each of

the mandibles, due to the detachment of a peculiar pair of cutting instruments, supposed

to be used by the insect for freeing itself when emerging from the pupal stage.

I propose to divide the subfamily into two divisions, consisting (I.) of the apterous,

(1I.) of the winged Otiorhynchine.

Series OTIORHYNCHINA APTERA.

Alse rudimentarise. Metanotum membraneum.

These important characters divide the Otiorhynchine in a natural manner, and

though they cannot be directly observed without breaking up the specimen, as the

elytra are frequently more or less soldered together in the apterous forms, yet it is very

easy to distinguish the members of the two groups by external minor characters. In the

‘“‘ Otiorhynchine aptere” there are no prominent shoulders to the elytra; the exposed

portion of the scutellum is usually very minute, and scarcely penetrates at all between

the exposed parts of the wing-cases; the metasternum is always short; and the part of

the mesothoracic episterna left uncovered by the elytra is small or moderate in size.

Although this latter point is very variable it is of great assistance in separating the

insects of the two groups, and indeed was made use of by Horn as a means of dividing

the family.

In the “ Otiorhynchine alate” the shoulders of the elytra are distinct and stand out

more or less laterally, the tip of the scutellum separates the exposed bases of the

elytra, the metasternum is either elongate or short, and the uncovered part of the

mesothoracic episterna is either moderate in size or large.

Group OPHRYASTINA.

This group includes all the apterous Otiorhynchine of our region that have. ocular

lobes on the prothorax. As regards this point it should be remarked that there are some

species in which it is difficult at first sight to determine whether ocular lobes are present

or not; but in such cases the form of the eye will determine the point, it being more

or less longitudinal in the greatest diameter when lobes are present, and transverse

when they are absent.

It includes two minor groups that it is unnecessary to distinguish here by names, viz.:

I. Rostrum with scrobes that are very deep and definite, even at their termination. Genera

Ophryastes, Tosastes, Caccophryastes, and Eupagoderes.

II. Rostrum with scrobes that are extremely broad and quite indefinite behind. Genus

Amphidees.

The genera of the first subgroup may be readily distinguished as follows :—

A. Tarsi without pubescence on the third joint.

1. Corbels of the posterior tibize more or less imperfectly cavernous . Ophryastes.

2. Corbels of the posterior tibize with laminate tip bearing only one

series of spinules externally (‘open corbels,” Lacord.) . . . . Tosastes.

B. Tarsi with adhesive pubescence on the lobes of the third joint.

1. Mentum concealing the palpi entirely . . . . . . . . . . Eupagoderes.

2. Palpi projecting beyond the apex of the mentum . . . . . . Caccophryastes.

OPHRYASTES.

Ophryastes (part.), Schénh. Gen. Cure. i. p. 508 (1833).

Dystirus, Pascoe, Journ. Linn. Soc., Zool. xi. p. 447.

Ophryastes, Leconte & Horn, Rhynchophora of N. Am. p. 30.

Although this genus cannot be defined by means of the tuberosities at the side of

the thorax, yet it may be satisfactorily separated from EHupagoderes by the absence of

adhesive pubescence from the lobes of the third tarsal joint. The tips of the hind tibie

are cavernous, as stated by Lacordaire, though in an imperfect and variable manner.

Ophryastes is peculiar to the arid regions of the Southern United States and Northern

Mexico. The species are no doubt epigeal in habits, though I have not seen any records

to this effect.

A very interesting North-American form may be at present placed in the genus,

though, no doubt, it will have to be ultimately separated *.

* Ophryastes wickhami, sp. n.

Griseus, dense squamosus, breviter hispidus ; rostro trisulcato, basi depresso; prothorace transverso, rugoso, ad

latera perparum incrassato; elytris subsulcatis, sulcis obsolete punctatis.

Long. cum rostro 19 millim.

Hab. Norra Amurica, Winslow, Arizona ( Wickham).

I name this species in honour of Mr. H. F. Wickham, to whom I am indebted for a considerable part of the

specimens that have enabled me to form some idea of the N.-American Ophryastini. The feet of O. wickhami

are rather broad, but have no horny projections beneath, these being replaced by membranous processes (formed

apparently by agglutinated cilie) coming from the side-margins of the joints; the tips of the hind tibie are

distinctly truncate, and the truncature is entirely filled by long cilis or scales, part of them directed inwards,

part outwards, but there are no marginal cilie. Mr. Wickham thought the species might be referable to 0.

desertus, Lec., but this is clearly not the case.

OPHRYASTES. 89

1. Ophryastes latipennis, sp. n. (Tab. IV. fig. 2.)

Latior, griseo-obscurus ; prothorace ad latera angulariter dilatato, grosse rugoso-sculpturato; elytris parum

profunde striatis, interstitiis nullo modo convexis, striis fortiter punctatis.

Long. 16 millim,

Hab. Mexico, Chihuahua city, Villa Lerdo in Durango (Hage).

Rostrum transversely impressed at the base; median groove very broad; lateral

grooves short, abruptly terminated above by the transverse impression. Thorax very

short and broad, with very coarse irregular sculpture; the lateral dilatation becoming

gradually broader till near the base, where it ceases very abruptly, leaving an angular

projection ; basal marginal band of tomentum very broad. The exposed apex of the

scutellum broad and short. Llytra very broad at the shoulders, of a uniform dark grey

colour, the sculpture consisting of series of rather large punctures, the interstices broad.

Tarsi stout, scaly beneath, the angles of joints 1-3 forming short horny projections.

Two specimens.

This species may be readily distinguished by the very broad elytra, the angular

form of the lateral projection on the thorax, and the very coarse sculpture of the latter

part.

2. Ophryastes strumosus.

Dystirus strumosus, Pasc. Journ. Linn. Soc., Zool. xi. p. 447, t. 18. fig. 103.

Hab. Mexico!, Arroyo Zarco (Sal/é).

We have received only one example that I can refer to this species. It has a

depression, though only a slight one, at the base of the rostrum; the thorax coarsely

and irregularly sculptured, the lateral expansion feebly bilobed, not angular behind ;

the elytra not striate, but with rows of deep, remarkably definite, broadly separated

punctures.

3. Ophryastes basalis, sp. n. .

Angustus, fusco-griseus, submaculatus; prothorace ad latera bilobo-dilatato, parcius sculpturato; elytris pro-

funde sat fortiter remote punctatis, interstitiis subconvexis.

Long. 104 millim.

Hab. Mexico, Arroyo Zarco (Saillé).

This species bears a general resemblance to 0. strwmosus, but differs by some very

important characters: there is no constriction or depression at the base of the rostrum

and the shoulders of the elytra do not stand out at all laterally. The base of the

thorax has the marginal part less definite than usual, and considerably extended in the

longitudinal direction. The median groove on the rostrum is moderately deep, and

terminates abruptly without extending on to the head; the lateral grooves are quite

short. The fimbrie of the ocular lobes are scanty. One example.

4. Ophryastes bituberosus, sp. n. (Tab. IV. fig. 1.)

Pallide griseus, fusco-submaculatus ; prothorace rugoso-sculpturato, ad latera bilobo-dilatato ; elytris confertim

fortiter seriatim punctatis, interstitiis subconvexis.

Long. 10-14 millim.

Hab. Mexico, Paso del Norte ({oge).

Rostrum without any basal depression; median groove very obsolete, not extending

on to the head; lateral groove seen from the side quite short, and with its inner margin

somewhat raised, seen from the front appearing elongate owing to the fusion with it of

a slight depression near the inner margin of the eye. Thorax very broad and short,

very coarsely rugose, the lateral expansion deeply emarginate in the middle. Scutellum

almost entirely concealed. Elytra with deep rows of large, rather closely-placed punc-

tures, the interstices being evidently convex; they are vaguely maculate, the suture

remaining pallid. Hight specimens.

This insect was pointed out to me by Dr. Horn as being possibly 0. tuberosus, Lec.,

and judging from the description it must be extremely similar to the North-American

species; but as O. bituberosus has no basal depression on the rostrum—a character of

great importance in Ophryastes—I think the two likely to be distinct.

I treat as a variety two specimens from the same locality, of broader form, and not

maculate, and with finer punctures on the elytra.

5. Ophryastes ovipennis, sp. n. (Tab. IV. fig. 3.)

Griseus ; prothorace brevissimo, ad latera posterius subhamato, obsolete sculpturato ; elytris convexis, humeris

omnino rotundatis, apice subacuminato, sulcatis, sulcis fortiter punctatis.

Long. 93 millim.

Hab. Mexico, Paso del Norte (Hége).

Rostrum without any trace of basal impression, with a fine deep median channel

extending from the.tip to the upper part of the vertex, and on each side with a short

deep lateral channel. ‘Thorax very short, the sculpture very coarse, but obsolete on

the disc, where also there is a vague broad channel; basal band of tomentum rather

small. Scutellum almost entirely concealed. Elytra subinflated, convex even at the

base, with shallow broad grooves in which are placed coarse punctures. Tarsi without

horny projections, but with semimembranous, projecting angles.

Two examples were found of this very distinct species; the male has the elytra

considerably less ample than the female, and the punctures are consequently more

closely placed.

TOSASTES, gen. nov.

Tarsi articulo tertio vix lobato, subtus absque pubescentia. Tibiw posteriores ad apicem simpliciter laminate,

nullo modo truncate.

This genus has an appearance very different to Ophryastes, though it appears to be

closely allied thereto; as, however, the apices of the hind tibiz are without any trace

of truncature, or of a second row of spinules, it is perhaps advisable to treat the two

forms as distinct genera. I cannot detect any other difference of true generic impor-

tance, though there are several minor peculiarities. The second ventral segment is

quite short, the first suture straight, the third and fourth segments very short. The

body is covered with overlapping scales as in Ophryastes. The ocular lobes are well

developed.

As remarked above, the facies is very different from Ophryastes; had it not been for

this I should not have separated the two, as the corbels of the hind tibie are in this

group in a transitionary condition, and differ from species to species.

1. Tosastes humeralis, sp. n. (Tab. IV. fig. 4.)

Ineequalis, rugosus, pallide griseus ; prothorace brevi, ante basin brevissime constricto, angulis posterioribus

minute prominulis; elytris basi truncato, angulis anterioribus acutis.

Long. cumque rostro 7-8 millim.

Hab. Mexico, Chihuahua city (Hége).

Covered with thin scales, which on the anterior parts are almost entirely fused into

a continuous indument, bearing also some scanty, very short sete. Rostrum short, with

a broad median groove and a large lateral impression on each side. Thorax strongly

transverse, very deeply rugose. LElytra quite truncate at the base, and with the angles

minutely prominent; very closely applied to the base of the thorax, and of exactly the

same width, so that the two are almost continuous in outline; the sculpture consists

of vague, large depressions, placed in series, and connected by obscure strie. Spinules

at the apex of the hind tibiz excessively short and broad, and very few in number.

Two specimens.

2. Tosastes globipennis, sp.n. (Tab. IV. fig. 5.)

Pallide griseus, obsolete sculpturatus ; coleopteris convexis, humeris rotundatis.

Long. cumque rostro 7} millim.

Hab. Mexico, Guajuco in Nuevo Leon (Dr. Palmer).

This insect differs at first sight from 7. humeralis by the elytra being quite destitute

of the acute humeral angle seen in that species. The rostrum has only very obsolete

impressions at the sides. The scape of the antenne is dark, the first six joints of

the funiculus are pale, the seventh being black like the club, and so closely applied

thereto as to appear a part of it. Thorax uneven, indistinctly sculptured, very

strongly transverse, closely applied to the base of the elytra at the angles, less so in

the middle, so that the scutellum is not quite concealed. Elytra with very obsolete

sculpture consisting of vague large pits, arranged serially. One specimen.

CACCOPHRYASTES, gen. nov.

Palpi maxillares exserti.

This genus is proposed for a species, of which we have received only a single

example, having the peculiarity of structure mentioned above, but in other respects very

closely allied to Ophryastes and Eupagoderes, and in fact much resembling 0. vittatus,

Say. I have hesitated as to whether the exposure of the maxillary palpi might not be

the result of some abnormality of structure, but I can find no reason for believing this

to be the case; and the mentum, moreover, is peculiarly formed, its front margin being

directed only slightly obliquely upwards, instead of abruptly as in all the other forms

of Ophryastini I have examined. There is a slight thickening of the sides of the

prothorax, but no distinet projection ; the third tarsal joint is bilobed, and each lobe

possesses a patch of adhesive pubescence beneath; the apex of the hind tibia is feebly

cavernous. The scutellum is rather largely exposed. The other characters are those

of Ophryastes and Eupagoderes.

There are other genera of Otiorhynchide with the mentum in front not covering

the palpi, but none of them are allied to Caccophryastes. Itis very possible that when

other examples of the species for which I have established the genus are found, it may

be discovered that the palpi are normally concealed by the mandibles when the mouth

is closed; but in that case the insertion of the palpi in sucha way as to project towards

the front of the mouth, instead of upwards towards its interior, will probably be found

to differentiate the genus satisfactorily.

1. Caccophryastes lineatus, sp.n. (Tab. IV. fig. 6.)

Pallide griseus, elytrorum striis fasco-lineatis ; prothorace inequaliter seulpturato, medio obsolete canaliculato,

lateribus rotundatis, subtumidulis.

Long. 10 millim.

Hab. Muxico, Durango city (Hdge).

Rostrum without basal constriction, with a deep elongate median channel extending

on to the forehead, and with a short, rather deep lateral impression. Thorax short,

with coarse unevenly distributed sculpture; ocular lobes feeble; the sides greatly

rounded and a little tumid, especially behind. Scutellum largely exposed behind the

margin of the thorax. Elytra slender, the humeri not at all prominent, the strie

rather fine and bearing somewhat distant, indistinct punctures; they are marked with

dark lines, and the alternate interstices are slightly paler. One specimen.

EUPAGODERES.

Eupagoderes, Horn, Rhynchophora of N. America, p. 32 (1876).

Ophryastes (part.), Schénherr, Gen. Cure. i. p. 508 (1833).

I take the existence of a definite patch of adhesive pubescence on each of the lobes

of the third tarsal joint to bea satisfactory means of distinguishing the species of

Eupagoderes from Ophryastes. The truncature of the hind tibia is usually more

perfectly cavernous than it is in Ophryastes. The genus as thus defined is susceptible

of further division, but this is quite unnecessary at present; the species being com-

paratively few, though doubtless many more remain to be discovered.

Eupagoderes is peculiar to the United States and Mexico, and has until now consisted

of about twelve species, to which I add seven others. The genus seems to be in

Mexico less exclusively confined to the north than Ophryastes is.

1. Kupagoderes constrictus, sp.n. (Tab. IV. fig. 7, 3.)

Pallide griseus, prothorace utrinque vage vittato; elytris ad basin depressis, quasi constrictis, subtiliter

striatis.

Long. 73-94 millim.

Hab. Mexico, San Isidro (Hoge).

This insect cannot be confounded with any other member of the genus, on account

of the peculiar neck-like prolongation at the front of the convex elytra, and of the

more than usually exposed scutellum. There is a feeble depression at the base of the

rostrum, and on its middle in front are two longitudinal elevations with a short broad

groove between them. Club of antenne small and stout. Thorax short, greatly

rounded at. the sides, with rather deep punctures irregularly distributed. The strie

on the elytra are quite fine, and only very obscurely punctate.

- Four specimens were found. The female has the elytra very much more ample than

the male, and the basal constriction considerably shorter.

We have received only two examples of this remarkable insect. It and the

following species will, no doubt, be ultimately separated under a distinct genus. In

E. speciosus the mentum has a very large rugose anterior portion; and the polished

plane at its base for it to slide over is very large and conspicuous.

Long. 22 millim.

Hab. Mexico, Villa Lerdo in Durango (Hoge).

Rostrum with three deep elongate grooves. Thorax much rounded at the sides,

rugose, with a deep channel all along the middle. Scutellum rather large. Elytra

very narrow and elongate, covered densely with fine scales, with series of large punc-

tures, and with the alternate interstices more elevated. Legs very long, white.

Mentum deeply depressed in the middle, the anterior part rugose and hispid with

erect sete.

A single example only of this conspicuous insect has been received. It is probably

a male, and the female may prove to be a much broader, heavier-looking insect.

4. Eupagoderes mexicanus, sp.n. (Tab. IV. fig. 10.)

Elongatus, niger, parce squamosus, submaculatus ; prothorace lateribus rotundatis, rugoso, medio canaliculato ;

Rostrum with three parallel grooves terminating abruptly above on one line.

Antenne black, with small club, which is scarcely broader than the eighth joint.

Thorax transverse, very strongly rounded at the sides, with coarse distant punctuation,

and a broad channel on the middle. Elytra with series of very distinct large punctures,

which are not connected by striation. Mentum with the margins not, or only

obscurely, raised. Eighteen specimens.

5. Eupagoderes durangoensis, sp. n.

Elongatus, angustus, niger, tenuiter squamosus ; prothorace punctato, medio obsolete canaliculato ; elytris

striatis, striis minus argute punctatis.

Similar to #. mexicanus, but rather smaller, with the elytra striate. The middle

channel of the rostrum obsolete, the lateral channel small, not extending up to the eye.

Thorax a good deal narrowed behind, coarsely irregularly punctate, with only a very

indistinct channel on the middle. Mentum with the lateral and hind margins strongly

and acutely raised. Four specimens, all in a bad state of preservation.

Closely allied to E. sallwi, but with the scales of the surface less densely packed,

the colour more obscure, the patches of adhesive pubescence on the tarsal lobes smaller,

and the mentum rather different in form, it being less transverse, and not so angular

at the sides; the latter is but feebly impressed, little sculptured, and very shining.

The typical example sent me from Schénherr’s collection by Dr. Aurivillius is con-

siderably smaller than any specimen of the series we have received, and differs slightly

in several other respects from our examples, but I do not see any way of distinguishing

it specifically. This individual came from Sturm’s collection, and two other examples

in our possession from the same collection appear to connect it satisfactorily with the

rest of our series.

7. Eupagoderes sallei. (Tab. IV. fig. 11.)

Ophryastes salle, Gyll. in Schénh. Gen. Cure. v. p. 820°.

Hab. Mexico (Sallé), Vera Cruz}.

I have seen only two examples of this species: one was obtained from Sallé’s collec-

tion, and therein was labelled “ O. sallet, type’’; the other is also a “type” from

Schonherr’s collection communicated by Dr. Aurivillius. 0. sall@i is one of the most

densely squamose species of the genus, and I think the maculation of the surface in

these individuals is in part, if not entirely, due to their being stained irregularly with

a very tenacious, muddy fluid. The legs are remarkably short. The rostrum is short,

without median groove, but with a vague basal, transverse impression. The mentum

is short and broad, greatly narrowed towards the base, depressed and shining in the

middle.

8. Hupagoderes squalidus, sp. n.

Fusco-griseus ; prothorace nitido, subtransverso, parce obsoleteque punctato, medio tenuiter canaliculato ;

elytris subtiliter striatis, striis remote minus fortiter punctatis.

Long. 10 millim.

Hab. Mexico (Sallé), Esperanza (Hoge).

Rostrum with a deep median channel, extending quite to its base, and with broad,

well-marked, lateral grooves. Thorax with only a few obscure and distant punctures,

and with an obsolete median channel. Elytra with fine striz separated by broad flat

intervals, and-bearing remote, moderately large, not deep punctures.

In this species the scales are very closely fastened to the surface, and, though dense,

the outline of each is quite distinct; on the disc of the thorax they have a peculiar

shining appearance, and are but little variegate, but on the rostrum and the sides of

the thorax are much paler than elsewhere, nearly white in fact. £. squalidus is at first

sight very similar to E. cinereus, but it has a rather larger thorax, which is obsoletely

punctured, a longer and deeper median channel on the rostrum, and the lateral channels

are parallel with this, not convergent above. ‘Two specimens.

This insect is very closely allied to E. sgualidus, and has a similar rostrum; but the

scales of the upper surface are white, and have not the peculiar nitid appearance that

they have in E. squalidus. It also resembles E. dunnianus, Casey, but the latter species

has a differently channelled rostrum.

One specimen only exists in our Mexican collections, but it agrees with a pair from

Arizona, sent to me by Captain Casey. The species may be known by its convex

forehead, by the median groove of the rostrum being absent, though represented by a

small fovea, by the deeply punctate thorax, by the fine strie on the elytra, and by the

squalid clothing thereon being variegated by darker patches. ‘The insect bears a

considerable general resemblance to H. cinereus. |

This is distinguished from all our other species by the apparent absence of fimbrie on

the ocular lobes. The rostrum has no transverse impression at the base, but the front

of the head has a separate convexity from the rostrum; there is a very vague broad

impression along the middle of the latter, terminating above in a sort of fovea; this

impression is due chiefly to a slight elevation of the inner margin of the lateral grooves,

these latter being elongate and definite. Thorax elongate, rounded at the sides, and

conyex longitudinally as well as transversely, destitute of basal margin. Hlytra small

and slender, with series of rather large deep punctures. Posterior tibiee thick at the

extremity and with unusually large apical truncature. The whole insect is covered

with somewhat shining scales, and the maculation is due to some of these being dark

in colour. Three examples.

The apparent absence of fimbrize from the ocular lobes suggests that this species may

belong to the genus Sapotes, Casey, but I do not think it necessary that it should be

separated from Hupagoderes at present.

AMPHIDEES.

Amphidees, Schéuherr, Gen. Cure. vi. 2, p. 252 (1842) ; Lacordaire, Gen. Col. vi. p. 242.

This genus was established by Schonherr for a single Mexican species, and I now

add several others. ‘These differ among themselves by small structural distinctions in

the ventral segments and apices of the hind tibie, as well as in the thickness of the

rostrum ; but I am quite unable to look on these minute structural characters as of

more than specific importance. A. pilosus differs rather more strongly, but I do not

think it necessary to separate even it at present.

Viewed in this way, I define Amphidees as embracing such ‘ Otiorhynchine aptere’

as have ocular lobes, and in which the rostral scrobes are broad and indefinite behind ;

this latter character being the essential point of distinction from Hupagoderes. In our

region, therefore, the genus is the equivalent of Horn’s group Strangaliodes. The

posterior corbels are more or less imperfectly cavernous, except in A. pilosus, where I

think they may be described as open.

1. Amphidees major, sp. n. (Tab. IV. fig. 13.)

Sat elongatus, equaliter squamosus; elytris versus apicem breviter setosis, seriatim sat remote punctatis,

interstitiis 3° et 5° parum elevatis, ceteris planis.

Long. cumque rostro 10 millim.

Hab. Mexico, Tepansacualco (Sal/é).

This greatly resembles an elongate Hupagoderes of the E. cinereus group of species,

and is covered with scales ina similar manner; the rostrum, too, is only a little more

slender, but its scrobes are excessively broad and vague posteriorly, so that a glance is

sufficient to enable one to appreciate the distinction between the two genera. The

forehead has a convexity slightly separate from the plane of the rostrum; the latter

has a vague elevation of its middle near the base, and in a line with this there is a

small longitudinal fovea on the forehead; the antenne are elongate and slender, the

first and second joints of the funiculus equal in length, the club elongate, slender, and

acuminate, the sutures distinct, the eighth joint very abruptly separated from the club.

Thorax strongly transverse, evenly rounded at the sides. Elytra considerably broader

than the thorax, with a raised margin behind the scutellum, which is unusually distinct ;

Hab. Mexico !, Parada, Capulalpam (Sad/é).

Rostrum rather slender in the middle, separated from the head only by a feeble

convexity of the latter, and without elevations or grooves. ‘Thorax much narrowed in

front and strongly rounded at the sides. Scutellum quite minute. LElytra with broad

base, and without trace of any margin even near the scutellum; shoulders greatly

rounded. Male with an impression on the middle of the basal ventral segment. ‘Three

specimens.

Though so different in form from A. major, I cannot detect any distinctions of a

generic character, except minute modifications of structure.

A. nubilosus is figured on our Plate under the name of A. curtus; but having now

received a type of A. nubilosus from Schénherr’s collection, I find our insect to belong

to that species.

3. Amphidees —— ?

Hab. Mexico, San Antonio de Arriba (Sallé).

I refer to this genus a pinned example of a very small species, resembling A. nwbi-

losus, but having the elytra finely striate and the interstices quite flat.

4. Amphidees macer, sp. n. (Tab. IV. fig. 15.)

Angustus, elongatus, tenuiter squamosus, parce pilosus; prothorace elongato; elytris striatis, striis parum

argute punctatis, interstitiis latis, levissime convexis.

Long. cumque rostro 10 millim.

Hab. Mexico, San Antonio de Arriba (Sal/é), Toluca (Hoge).

Covered with scales, some of which are jewel-like, more especially on the head,

rostrum, and thorax; also with scanty, fine, long sete. Rostrum with a convexity

distinct from that of the head. Thorax elongate, with some very distant, rather fine

punctures scattered between the scales. Elytra slender and elongate, with moderately

AMPHIDEES. 99

large punctures placed in feeble grooves, the interstices broad, slightly convex, all

similar. Male with a depression on the apical ventral segment. Three specimens.

In this species the ocular lobes are but little prominent. An example of this insect

was labelled in Sallé’s collection “ Scoteborus (Peritaria, Horn) sp.”; but the first

generic name is quite erroneous.

5. Amphidees nasutus, sp. n.

Gracilis, niger, fusco-squamosus, in elytris hispidus; rostro elongato, apice latiore.

Long. 8-83 millim.

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

Antenne reddish, with the club nearly black; first and second joints of funiculus

elongate, the latter a little the longer. Rostrum elongate, longer than the thorax, much

dilated at the tip, with the pterygia and a part of the scrobes visible from above, with

two very indistinct longitudinal impressions on the basal part, indistinctly carinate on

each side in front; eyes touching the thoracic margin. Thorax transverse, much

rounded at the sides, the surface finely granulate, each granule bearing a scale.

Scutellum distinct, glabrous, not quite horizontal, being slightly elevated at the tip.

Hlytra with series of coarse punctures concealed by the squamosity with which they

are clothed, and with numerous erect, fine, but rigid, setee. Legs slender, the posterior

tibiee much broader at the tip; the apical cilia are directed towards the tarsus, but

there is no trace of any incrassation or truncature external to the cilia. Two

specimens. |

This species is well distinguished from its congeners by the longer rostrum.

6. Amphidees alternans, sp. n.

Elongatus, squamosus, submaculatus, elytris parce hispidulis; prothorace in medio tenuiter canaliculato ;

elytris seriatim punctatis, interstitiis latis, alternis magis elevatis.

Long. cumque rostro 9-10 millim.

Hab. Mexico, Jacale (Salié).

This isa more elongate and narrow insect than A. major, and in respect of the

clothing of the surface is intermediate between it and 4. longulus, the squamosity

being distinct, and yet evidently covering a finely rugose surface. Forehead with a

fovea in front; rostrum very indistinctly longitudinally impressed at the base. Thorax

narrowed in front, and much rounded at the sides, the surface rugose, but the rugosities

concealed by the scales, except at a patch on each side at the base ; finely channelled

along the middle. Scutellum small but distinct, the suture very slightly raised just

behind it. Hlytra elongate, covered with scales which form an indefinite maculation,

bearing series of moderately large punctures, and with the alternate interstices distinctly

raised. Three specimens in bad preservation.

7. Amphidees longulus, sp.n. (Tab. IV. fig. 17.)

Angustulus, sat elongatus, sordide squamosus, hispidus ; prothorace dense rugoso, medio tenuiter canaliculato ;

elytris seriatim fortiter punctatis, interstitiis minus latis.

Long. cumque rostro 6-7 millim.

Hab. Mexico, San Antonio de Arriba (Sad/é), Tehuacan (//ége).

This species is covered with a squalid squamosity, which is apparently caducous, and

the surface is frequently discoloured with dirt; it is hispid with fine hairs which are not

at all dense, and are either black or grey in colour. The rostrum is rather short, with

no impressions ; on the front of the forehead there is a minute fovea. ‘Thorax greatly

rounded at the sides, equally narrowed in front and behind, with the surface rugose,

the interstices squamose ; there is a channel along the middle. Scutellum very minute.

Elytra oblong, with regular series of moderately large punctures, separated by rather

small intervals. The male has a large oblong impression extending from the hind

margin of the metasternum to near the hind margin of the second ventral segment.

Hoge found a good series of this species, but nearly all the specimens are very dirty,

“and apparently the dirt and squamosity become agglutinated by some exudation.

The second ventral segment is rather shorter in this species than in the allies.

Dr. Horn pointed it out in our collection as similar to Peritaxia rugicollis; I should

not, however, from his generic table, refer it to Peritaxia at all, the first ventral suture

being nearly straight, and the second segment scarcely so long as the following two

together, which would bring it into the first group of genera distinguished by the table

on p. 38 in the “ Rhynchophora of N. America.”

Nocheles vestitus, Casey, is an allied but distinct species.

8. Amphidees pilosus, sp.n. (Tab. IV. fig. 16.)

Niger, opacus, pilosus, rostro prothoraceque rugosis, subsquamosis ; elytris profunde striatis, striis sat fortiter

punctatis.

Long. cumque rostro 7 millim.

Hab. Mexico, Paso del Norte (//ége).

Rostrum short, stout, and curved, separated from the head by a deep transverse

curved groove. Antenne rather short, the club acuminate, black, the preceding joint

broad. ‘Thorax much rounded at the sides, densely rugose. Scutellum very minute.

Elytra suboval, with definite broad striz, in which are punctures placed very near to

one another. First ventral segment strongly arcuate, in the middle slightly longer than

the two following together. One specimen.

This is distinguished from all our other species by the pilosity of the surface, and by

the deep groove separating the rostrum from the head. The lamine of the apex of

the hind tibia are scarcely perceptibly flexed inwards, so that the corbels are open.

There is a feeble squamosity of the surface, the scales apparently being delicate and

AMPHIDEES, 101

caducous. In many respects the insect agrees with Horn’s genus Peritawxia, containing

two North-American species, one of which (P. hispida) is said to be destitute of ocular

lobes. In A. pilosus the ocular lobes are very feeble, though undoubtedly extant; but

I cannot think it likely to be allied to P. hispida, as Horn makes no allusion to the

remarkable transverse constriction at the base of the rostrum.

Group EPICHRINA.

This group includes all the apterous Otiorhynchine of our region that have no

ocular lobes to the thorax, and in which the scrobes—whether definite or indefinite—

are entirely lateral, with their lower border arcuate to a greater or less extent, and

the claws are free. These characters are strictly diagnostic, and in addition it may

be added that the scape of the antenna is always moderate in thickness, never

incrassate, never extremely slender. The corbels of the hind tibize vary much, but it

may be considered as a character of the group that they are cavernous or subcavernous,

the tip of the tibia never being extremely slender, as is the normal condition in the

Sciaphilina.

Horn’s “Tribe Brachyderini”’ is no doubt nearly equivalent with this group. He,

however, remarks very truly (Rhynchophora of N. America, p. 16) that “the tribe is

widely different from that defined by Lacordaire under the same name ;” this being

the case—both definition and composition of the group differing entirely from

Lacordaire’s “‘ Brachydérides ” or “ Brachydérides vrais ”—it seems preferable to adopt

a fresh name for the group, as I have done here.

The greater part of our Epicerina are hitherto undescribed. In arranging them

into genera I have endeavoured to adopt a middle course, striving at the same time to

propose as few genera as possible, and to avoid placing in one genus insects strikingly

different as regards the points that have been treated as of generic importance by

Lacordaire and by Horn.

_I find myself obliged to adopt fourteen genera: the following table, though not

expressing the affinities of the genera, may help future students to determine their

insects of this group :—

Front femora unarmed.

Scrobes very indefinite and broad behind. . . . 2... . Deamphus.

Scrobes deep behind, with upper and lower borders subparallel.

times shorter, than the first joint.

DEAMPHUS, gen. nov.

Rostrum breve, scrobibus latissimis, posterius evanescentibus, ad latera sitis, descendentibus.

I propose this genus for some insects differing greatly from Epicwrus in the form of

the scrobes, which are extremely broad and vague behind. The rostrum is very short,

not longer than the head. The scape of the antennze is rather long and passes the eye ;

this latter is round and placed far in front of the thorax. The thorax is broad and

strongly transverse; it entirely covers the very large scutellum, which does not penetrate

between the elytra. These latter are short, with rounded, not prominent shoulders.

The middle coxe are only slightly separated, the epipleura is rounded at the shoulder,

and the mesothoracic epimeron is quite minute. The metasternum is very short. The

corbels of the posterior tibize are feebly cavernous.

These insects do not much resemble Epicerus in appearance, and in this respect come

nearer to Amphidees ; there is, however, no trace of any ocular lobes on the thorax, so

that the genus must be separated from the forms I have included in Amphidees. ‘The

Colombian genus Amphideritus resembles Deamphus in the form of the scrobes, and

also in its general appearance; but it has the elytra broader than the thorax, and the

scutellum visible at the base of the suture, so that it probably belongs in the “ Otio-

rhynchine alate.” In each of these two genera the front coxe are minutely

DEAMPHUS. 103

separated, but in Amphideritus there is a post-coxal process that is not found in

Deamphus.

1. Deamphus brevipennis, sp.n. (Tab. V. fig. 1.)

Niger, tenuiter setosus, antennis piceis ; prothorace valde transverso, lateribus rugosis, disco punctato, nitido *

elytris seriatim fortiter, minus argute punctatis.

Long. 62 millim.

Hab. GUATEMALA, Quezaltenango 7800 feet (Champion).

Rostrum short, coarsely and closely punctate, shining, rather deeply impressed along

the middle, with a fovea between the eyes; the latter a little convex. Thorax broad,

close. to the front abruptly narrowed, and also much narrowed near the base, the

basal margin distinct; rugose-punctate, except on the disc, where the punctuation is

more scanty. Elytra short, with series of coarse, but not deep punctures. Legs

elongate. One specimen.

This species is not much like any other known from our region. It somewhat

resembles Peritaxia rugicollis, Horn, though that is a much more elongate insect.

2. Deamphus deceptor, sp. n.

Nigro-piceus, nitidus, parce setosus, in elytris submaculatus; prothorace fortiter rugoso; elytris profunde

grosseque seriatim punctatis.

Long. 7-8 millim.

Hab. GuatemaLa, Quiche Mountains 7000 to 9000 feet, San Gerénimo 3000 feet

(Champion). |

| Closely allied to D. brevipennis, but with a much coarser sculpture on the thorax ;

the surface bears a scanty depressed setosity of a pinkish-grey colour, and on the elytra

these scale-like sete are more abundant in some places, so as to form a vague pattern.

In the male the thorax is rather more dilated at the sides than it is in the female.

Six specimens. |

3. Deamphus latifrons, sp.n. (Tab. V. fig. 2.)

Gracilis, elongatus, piceus, squamosus parciusque setosus ; elytris punctato-striatis.

Long. 11-12 millim.

Hab. Mexico, Hacienda de San Miguelito (Dr. Palmer), Refugio in Durango (Héqe).

Evenly covered with round, closely-adherent scales of a greyish or ashy colour, these

scales nowhere overlapping one another ; the surface also bears fine, rather long, scanty

hairs. Rostrum very short and broad, separated from the head by a broad obscure

depression, in which there is placed an indistinct fovea; eyes very widely separated,

round, rather convex ; antenne dark red, setose. Thorax strongly transverse, rounded

at the sides, rather narrower at the base than in front, quite even, and without basal

104 RHYNCHOPHORA.

margin; rather deeply punctate, but the sculpture obscured by the clothing. Llytra

slender, oval, rounded at the shoulders, marked with fine, shallow striz, which are

indistinctly punctured ; the setee are pallid in colour, and much longer than those on

the head and thorax. Legs reddish. Corbels of hind tibiz almost simply laminate

externally. Four specimens.

This species bears a considerable resemblance to Amphidees macer; but that insect

has well-marked ocular lobes, whereas in D. latifrons these are quite absent. The

corbels of the hind tibiee would, no doubt, have been called open by Lacordaire.

4, Deamphus puncticollis, sp. n.

Gracilis, piceus, squamosus et setosus, squamulis submetallico-micantibus; rostro fere subcylindrico; elytris

subtiliter punctato-striatis.

Long. 74 millim.

Hab. Mexico, Huitzilac in Morelos (Hége).

Rostrum subcylindrical, very coarsely punctate, with a few opalescent scales between

the punctures, scarcely transversely depressed between the eyes ; antennz dusky red.

Thorax transverse, much rounded at the sides, narrowed and a little constricted in

front, strongly setose, rather coarsely punctate, with opalescent scales between the

punctures. Elytra slender, the shoulders not at all prominent ; with series of rather

coarse punctures, squamose, and with numerous fine elongate sete. One specimen.

Besides being much smaller than D. latifrons, this species has a more slender,

cylindrical rostrum.

EPICARUS.

Epicerus, Schonherr, Gen. Cure. ii. p. 3238 (1834) ; Lacordaire, Gen. Col. vi. p. 132; Horn,

Rhynch. N. Amer. p. 20.

This extensive genus is almost peculiar to our region, as in addition to those here

enumerated, two species of it from the United States of North America are all that are

known. It is, however, extremely close to the Palearctic genus Barynotus—so much

so indeed, that I do not myself see any satisfactory way of distinguishing the two.

The genus is a peculiarly difficult one to deal with, the sexes of some species differing

greatly in size and form. But these sexual distinctions seem to be by no means

constant, while in allied species they are yet of a slightly different nature; thus it is

extremely difficult to decide, from the inspection of a few specimens, where the specific

limits should be drawn.

I divide the genus, in the hope of facilitating the determination of the species, into

three groups, one of which is natural and easily recognized; on the other hand, the

distinction between the second and third groups is a very vague and variable one.

EPICZERUS. 105

Group 1.—Thorax broad, narrowed and contracted behind, its dorsal surface very coarsely sculp-

tured, usually with a broad irregular groove along the middle. Sculpture of the elytra very

coarse. Rostrum broad at the tip. Species 1-11.

Group 2.—Thorax subconical or subcylindric in form, with only a vague channel on the middle.

Rostrum usually a little more slender towards the tip and the pterygia but little visible.

Species 12-38.

Grovr 3.—Thorax without the peculiar form and sculpture of Group 1. The rostrum usually a

little broader towards the tip, with the pterygia exposed. Species 39-52.

Group 1.—Thorax broad, constricted behind, very coarsely sculptured, with a broad

groove along the middle. (Diorynotus, Jekel, in litt.) (Species 1-11.)

1. Epicerus vilis, sp.n. (Tab. IV. fig. 18, 2.)

Minus elongatus, niger, obsolete squamosus, inzequalis, grosse sed vage et parum profunde sculpturatus ; elytris

interstitiis 3°, 5°, 7° latis, posterius obsoletescentibus ; rostro medio sulcato.

Long. 11-13 millim.

Hab. Mexico, Salazar, Morelia in Michoacan, Esperanza, Mexico city (Hége), Toluca,

Parada (Sallé). |

One of the smallest and most squalid species of this group, the sculpture being very

coarse, vague, and indefinite, while the surface appears almost destitute of squamosity ;

on examining under a strong lens the surface looks as if the scales were present, but

partially dissolved away, as though by the action of some corrosive agent. The thorax

is not elongate; the median groove on it is indefinite, and in the female is usually quite

interrupted in the middle. ‘The surface between the ribs of the elytra is irregularly

impressed, the sculpture consisting of two series of large punctures that are more or

less confluent, and usually more definite in the male than in the female.

We have received about twenty examples that I assign to this species; they exhibit

considerable variation in size, shape, and sculpture.

2. Epiczrus cognatus, sp. n.

Niger, obsolete sqamosus, grosse sculpturatus; rostro medio canaliculato, utrmque canalicula breviore minus

arguta munito; elytris interstitiis 3°, 5°, 7° sat alte elevatis,

Long. 11-15 millim.

Hab. Mexico, Esperanza, Mexico city (Hége).

This insect may be distinguished from LE. vilis by the presence, on each side of the

rostrum near the front, of an additional, though vague, groove ; the sculpture is better

defined, the alternate interstices of the elytra form more definite coste, and the general

form is on the average more elongate. The channel on the middle of the thorax is

BIOL. CENTR.-AMER., Coleopt., Vol. IV. Pt. 8, October 1891. PP

106 RHYNCHOPHORA.

deep, and the coste on the wing-cases are distinctly elevated even on the part where

they all join.

The males differ from the females by their more slender form.

3. Epicerus calvus, sp,n. (Tab. IV. fig. 19, ¢ .)

Minus elongatus, niger, fere nudus, profunde sculpturatus ; elytris interstitiis 3°, 5°, 7° argute elevatis, inter-

vallis profunde sculpturatis ; rostro medio sulcato.

Long. 17 millim.

Hab. Mexico, Orizaba (Sal/lé).

This appears to be more completely free from squamosity than any of the other

species of the genus, and is of a jet-black colour. The rostrum is broad and short,

with a fine, very definite channel on the middle. The rugose sculpture on the thorax

is remarkably deep, and there is a median, deep, rugose groove, a little interrupted in

the middle. The elevated coste of the elytra are very definite, and the two series of

large punctures in the groove between each pair of coste are distinct; indeed the

longitudinal interval separating them is more definite than usual. One pair.

4, Epicerus sulcirostris, sp. n.

Brevis, niger, subsquamosus; elytris interstitiis 3°, 5°, 7° sat elevatis, intervallis grosse punctatis; rostro

medio late sulcato.

Long. 13 millim.

Hab. Mexico, Esperanza (Hoge).

This is one of the species with black, apparently denuded surface, but which is

nevertheless nearly covered with scales closely adpressed to the surface, and not at all

overlapping; although greatly resembling JZ. vilis, it may be recognized by the deep,

remarkably broad, depression that extends from between the eyes to the apex of the

rostrum. The thorax is short and broad, with an obsolete sulcus along the middle

and vague rugosities on the lateral portions. The coste of the elytra are well-marked,

but not strongly elevated, and are nearly as definite behind as they are in front; the

broad grooves between them are almost entirely occupied by two series of large vague

punctures or pits.

Two specimens only have been received. They appear to represent the sexes, though

there is but little difference between them ; if of one sex, both are, no doubt, females.

5. Epicerus niger, sp. n.

Elongatus, niger, obsolete squamosus ; rostro medio canaliculato ; elytris interstitiis 3°, 5°, 7° argutis, sat latis,

parum alte elevatis, punctis inter costas confertis.

Long. 13 millim.

Hab. Mexico, Orizaba (Sallé).

This is another of the species which to the unaided eye appears black, and destitute

EPICERUS. 107

of squamosity, but that is really clothed with inconspicuous scales. It is of compara-

tively narrow and elongate form, and is also distinguished by the regular coste, which,

however, are not strongly elevated, and by the numerous and closely placed large

punctures on the spaces or intervals between them. The thorax has the groove

along the middle entire, rather narrow, the lateral sculpture scanty, and not forming

a continuous depressed space.

Two specimens from Sallé’s collection are labelled “ Epicwrus niger, Chevr.;” a

mutilated example in my own possession is labelled “ H. aléernans, Jekel.”

6. Epicerus centralis, sp. n.

Elongatus, niger, tenuiter squamosus ; elytris interstitiis 3°, 5°, 7° parum elevatis; prothorace haud discrete

sulcato; rostro medio canaliculato.

Long. 12-14 millim.

Hab. Mexico, Guanajuato (Sallé).

I distinguish from Z. vilis four individuals of more elongate form, with a greater

amount of pallid squamosity on the surface, and with the raised coste of the elytra

less definite. They are separable from E. cognatus by these characters, and by the

rostrum having on the middle only a single groove. The thorax bears numerous

coarse rugosities, but exhibits no definite sulcus along the middle, though the rugosities

there are more continuous and confluent than elsewhere. The sculpture between the

slightly elevated coste of the wing-cases is coarse and deep, though indefinite.

Three males and one female. The female example is much larger and broader than

the males.

7. Epicerus zqualis, sp.n. (Tab. IV. fig. 20.)

Elongatus, niger, obsolete squamosus ; prothorace ubique rugoso, medio sulcato; elytris profunde regulariter,

fortiter seriatim punctatis, interstitiis alternis vix magis elevatis ; rostro trisulcato.

Long. 17 millim.

Hab. Mexico, Orizaba (Sal/é).

Although we have received only one example, a male, of this species, it appears to

be readily distinguished from all others of the genus by the sculpture of the elytra

consisting of very large, regularly-placed punctures, while the alternate interstices are

only very obscurely elevated. The rugose punctures of the thorax are evenly distributed,

so that there is no trace of lateral impressions, although the median groove is quite

distinct. ‘The three grooves on the rostrum are very distinct.

8. Epicerus uniformis, sp. n.

Niger, dense, pallide griseo-squamosus ; elytris interstitiis 3°, 5°, 7° sat elevatis, 7° nudo; prothorace rugoso,

vix in medio sulcato ; rostro medio canaliculato.

Long. 13 millim.

Hab. Mexico, Puebla (Sallé).

108 RHYNCHOPHORA.

This is more uniformly covered with pallid scales than the other species of the genus ;

the scales are very minute and cover the internal two coste, but the outer of the three

raised coste is nearly bare and dark in colour. The rostrum is rather short. The

surface of the thorax is uneven, and has a feeble rugose depression along the middle,

but this is not limited by any definite smooth space. ‘The first and second of the three

coste on the elytra are vot much elevated, and the sculpture in the grooves between

them is very shallow. The female is much broader than the male. Three specimens.

E. coxalis, which in some respects is like this species, has a tubercle on the middle

coxa, and the squamosity of the surface brownish in colour, not nearly white as in

E. uniformis.

9. Epicerus coxalis, sp.n. (Tab. IV. fig. 21.)

Niger, pallide brunneo-squamosus ; rostro parce squamoso, medio minus profunde sulcato; elytris dense

squamosis, interstitiis alternis elevatis haud altis ; coxis intermediis tuberculo minuto munitis.

Long. 14-17 millim.

Hab. Mexico, Amula 6000 feet, Omilteme 8000 feet, Chilpancingo 4600 feet, Xucu-

manatlan 7000 feet, all in Guerrero (H. H. Smith).

The small tubercle on the middle coxa is diagnostic of this species, as I have not

been able to find it in any other. No other species before me of this group has the

elytra so densely and uniformly clothed with scales. The rostrum is shining, black,

covered with delicate and small, pallid, rather widely separated scales, with a rather

feeble channel along the middle that scarcely reaches a fovea placed on the middle of

the vertex ; the eye is surrounded by a black orbit, and outside this there is a deep

impression extending all round the front part of the eye, and just before this, on each

side of the front of the rostrum, there is a short curvate depression. The thorax is

very irregularly sculptured ; there is a broad longitudinal depression along the middle,

and outside this a still broader depression; the depressions are more or less rugose,

and are densely covered with scales, which are of a larger size than those placed on the

elevated parts. The elytra are elongate, the suture only slightly raised, the third, fifth,

and seventh interstices more distinctly raised, the sculpture on the depressed spaces

between them being very indistinct ; the coste are covered with scales, and those on

the outer costa are usually smaller and more delicate than elsewhere; mixed with

the scales there are excessively short sete. The legs bear a squamosity similar to that

of the rostrum.

Kighteen examples; the males are very much more slender in form than the females,

and have a long acute mucro at the end of the posterior tibia in front; they also have

the apical portion of the elytra different in shape from the female.

EPICARUS. 109

10. Epicerus costicollis, sp. n.

Sat elongatus, niger, dense brunneo-squamosus, subvariegatus; prothorace ubique rugoso, medio late suleato ;

elytris interstitiis 3°, 5°, 7° elevatis, angustis.

Long. 14 millim.

Hab. Mexico, Yolotepec (Sallé).

Rostrum not so densely clothed with scales as the thorax and elytra, the scales

metallic. Thorax very rugose, with a longitudinal depression along the middle, which

is limited on each side by an elevation, the latter narrow, so as to appear like an irregular

costa. The coste on the elytra are rather narrow, sharply raised, and continue so to

their point of common union before the extremity ; the grooves between them are broad,

and have only a few very indefinite and very large vague depressions to represent the

punctures. One pair.

This species is most like E. coxalis, but is of rather shorter form, has no tubercle on

the middle coxe, and the scales have a distinctly metallic appearance. I have no doubt

the specimens are of one species, though the male has the groove on the rostrum very

obsolete, while it is quite distinct in the female.

11. Epicerus costatus, sp.n. (Tab. IV. fig. 22, ¢.)

Elongatus, elytris interstitiis 3°, 5°, 7° elevatis, integris, plumbeo-nitentibus, intervallis dense squamosis ;

rostro medio canaliculato.

Long. 18-19 millim.

Hab. Mexico, Puebla (Sallé), Amecameca (Hége).

E. costatus is the most elegant species of this group, and it can be very easily

identified by the great development of the alternate elytral interstices, and the

diminution of the sculpture between them—it thus results that the second, fourth,

and sixth interstices cannot be recognized at all. The rostrum is rather longer than

usual, considerably widened in front, and very distinctly but not broadly sulcate along

the middle. The thorax has a shallow longitudinal median sulcus, which is slightly

interrupted about the middle; outside this is an irregular, comparatively smooth

space; the lateral part of the surface is very coarsely though not deeply rugose. The

cost on the wing-cases are remarkably definite, and contrast strongly with the spaces

between them, which are densely covered with very minute, pallid (in the typical

form white) scales. ‘The legs are only feebly squamose. The swelling or incrassation

of the front tibia at the tip of its posterior face is more developed in this than in any

other species of the genus. The female is much broader than the male.

The three specimens from Sallé’s collection I treat as the typical form of the species ;

they have the scales in the grooves of the elytra almost white, while in the two

examples from Amecameca they are pale brown.

Group 2.—Rostrum usually not broader—even a little narrower—towards the tip ;

thorax subconical or subcylindric in form. (Species 12-38.)

This group contains a number of discrepant forms, which cannot be tabularly sepa-

rated in a practically useful way, the slight structural distinctions varying from species

to species in a very perplexing manner.

12. Epicerus mexicanus.

Epicerus mexicanus, Boh. in Schénh. Gen. Cure. ii, p. 324°; vi. 2, p. 271°.

Epicerus eruginosus, Boh. op. cit. vi. 2, p. 276°.

Epicerus cyphus, Boh. t. c. p. 272°.

Epicerus transversepunctatus, Boh. t. c. p. 271°.

Hab. Mexico 12345, Tierra Colorada and Omilteme, both in Guerrero (H. #.

Smith), Chilpancingo (Hége), Orizaba (Godman, Sallé), Vera Cruz, Toxpam, Guana-

juato (Sallé), Oaxaca, Misantla, Jalapa (Hége).

This is a very variable insect and presents considerable sexual differences, which

also appear to be inconstant. The size and colour, the punctuation of the elytra, the

shape of the thorax, and the impression of the rostrum all exhibit much discrepancy in

the large series before me, and yet after repeated attempts I fail to discover any constant

characters as marks of specific distinction. J have examined the cedeagus in four of

the varieties, and though I find it presents slight differences in each of them I do not

think these are beyond the range of variation possible in this organ. I must, however,

state that I am by no means sure that there may not prove to be several closely allied

but variable species. I had decided from Boheman’s descriptions that his £. mexicanus,

E. eruginosus, EL. cyphus, and E. transversepunctatus all referred to one variable

species, and the types since sent me from Schonherr’s collection by Dr. Aurivillius

quite confirm this view.

13. Epicerus fallax.

Epicerus fallax, Boh. in Schonh. Gen. Cure. vi. 2, p. 274°.

Hab. Mexico! (Sallé; coll. Sharp).

This insect is extremely similar to some of the varieties of E. mexicanus; but the

female can be distinguished by a glance at the peculiar form of the apical portion of

the wing-cases, the sutural part projecting backwards just before the declivity in an

abrupt manner instead of being broadly rounded. The male is much more likely to

be passed over as being E. mexicanus, but this sex of EL. fallax may be satistactorily

determined by the following slight peculiarities: the thorax is not rounded at the

sides and constricted behind, but straight, and from the middle to the front gently

narrowed ; its surface is more even than that of E. mewxicanus, the only inequality that

EPICERUS. | 111

can be detected being a slight channel along the middle of the basal half; the outline

of the front margin of the thorax at the sides is more sinuate, or, in other words,

rudimentary ocular lobes are undoubtedly present. E. fallax is apparently a rare

insect, as the collections received by our editors contain only a pair of the species, and

there are two pairs of old specimens in my own collection; these were all named

L. fallax—those in my own collection on the authority of Jekel—and they agree with

the type of the species sent me by Dr. Aurivillius. |

14. Epicerus nebulosus.

? Epicerus nebulosus, Boh. in Schénh. Gen. Cure. ii. p. 326"; vi. 2, p. 2777.

Hab. Mexico 1”, Cordova, Toxpam, Vera Cruz (Sallé), Oaxaca (Hoge).

This is another variable species, certain specimens of which resemble extremely

some of the varieties of EL. mexicanus. E. nebulosus may, however, always be distin-

guished from the commoner species by the following characters: the rostrum is

shorter; the eyes are more convex; the head behind the eyes is subconstricted and

the outline of the front of the thorax at the sides is very sinuate, so that a distinct, if

rudimentary, ocular lobe is present. The rostrum in £. nebulosus is in each sex

deeply impressed, and the sides of the depression are more abruptly raised, and

converge less at the forehead. . nebulosus is apparently not a common insect, and

nearly all of the fourteen specimens we have received of it are old examples from

Sallé’s collection. The marks on the wing-cases—on which Boheman chiefly relied

when discriminating E. nebulosus—are distinct in some examples only, being in others

entirely absent. The size of the individual is on the average very much less than it is

in L. mexicanus, but the largest examples considerably exceed the smaller specimens

of the commoner species in stature.

The example sent me as /. nebulosus from Schonherr’s collection is a small male of

ff. mexicanus, but I anticipate that other specimens in the Schonherrian collection

may prove to be the insect I now call E. nebulosus; if this, however, should not be

the case the species will require a new name. .

15. Epicerus cultripennis. (Tab. V. figg. 8, 3a, ¢; 4,44, 2.)

Epicerus cultripennis, Boh. in Schonh. Gen. Cure. vi. 2, p. 2737.

Epicerus depilis, Boh. t. ¢. p. 279°,

Hab. Mexico 1?, Jalapa, Misantla (Hége), Toxpam (Sallé), Orizaba (Godman, H. H.

Smith).

E. cultripennis was described! by Boheman from specimens (or a specimen) sent to

him by Chevrolat, and I think his description on the whole applies better to the

species we figure than to any other; and a small series of examples in my own

collection were so named by the late M. Jekel. The examples of EL. cultripennis in

112 RHYNCHOPHORA.

Sallé’s collection were, however, labelled E. depilis, Schonh., which I consider to be

the male sex, in a worn condition, of E. cultripennis. An example of EF. cultripennis

sent from Chevrolat’s collection by Dr. Aurivillius is a female of this species.

E. cultripennis has the thorax obscurely punctate, and, in addition, more or less

coarsely and abundantly transversely rugose-sulcate. ‘The insect is unusually elongate

in proportion to its width, and the thorax is remarkably long; viewed in profile, the

angle at the junction of the dorsal and apical parts of the wing-cases is much less

broadly rounded than usual, the apical part being perpendicular; the sexual disparity

is very marked, the female being usually quite twice the size of the male, the outline

of the body in the latter sex being so slender and parallel as to remind one of the

genus Lirus.

We figure the species in profile so as to allow an idea to be formed of the

sexual distinctions in the shape. Such distinctions exist in many other species of the

genus, though usually to a less extent than in H. cultripennis; indeed they vary not

only from species to species, but also in the same species to a certain extent; the

variation apparently being due to the fact that some males partake to a greater or less

extent of the peculiar sexual outlines of the female.

Boheman’s description of E. depilis no doubt refers to worn examples of the male of

E. cultripennis, and a specimen sent from Schonherr’s collection—not, however, the

type—as L. depilis is certainly E. cultripennis, 3 .

16. Epicerus inflatus, sp.n. (Tab. V. fig. 5.)

Anguste ovalis, convexus, niger, nitidus, fortius punctatus, fere esquamosus.

Long. 103 millim.

Hab. Mexico, Yolotepec (Sal/é).

Rostrum rather short and broad, moderately deeply impressed on the middle,

without fovea on the forehead. Thorax narrowed in front, not elongate, not con-

stricted behind, with coarse rugulose sculpture and a very feeble depression along the

middle, the fine basal margin unusually distinct and definite. LElytra not elongate,

convex, rounded at the sides, with the surface uneven and with series of rather large

punctures ; there is a slight squamosity on the depressed spots. ‘Two specimens.

The bare surface is not, I believe, due to abrasion, the two specimens being in very

good preservation. They represent, I think, the sexes, the female having the elytra

rather more convex.

17. Epicerus frontere, sp.n. (Tab. V. fig. 6.)

Pyriformis, convexus, niger, fusco-setosus; prothorace fortiter punctato, transversim subcylindrico ; elytris

regulariter seriatim punctatis.

Long. 13 millim.

Hab. Mexico, Frontera in Tabasco (Héoge, H. H. Smith).

EPICARUS. 113

A very distinct species, the clothing being rather setiform than squamiform, and the

outline peculiar, recalling that of a large Apion. The rostrum is short and broad,

deeply and broadly impressed in front, with a fovea on the forehead. The thorax is

but little narrowed in front, and bears numerous large punctures. ‘The elytra are only

about as broad at the base as the thorax, but become much broader to behind the

middle, and are also very convex and rounded behind; the punctures of the series are

unusually definite and distinct though rather small. Two specimens of uncertain sex.

The setose squamosity is no doubt very readily abraded and it then leaves the surface

quite bare.

18. Epiczrus reversus, sp. n.

Elongatus, ovalis, niger, griseo-squamosus, ad latera et subtus albidus ; rostro profunde angulariter impresso ;

prothorace parce profunde punctato; elytris seriatim foveolatis.

Long. 94-12 millim.

Hab. Mexico, San Andres Tuxtla (Sallé), Teapa in Tabasco (H. H. Smith).

Rostrum rather short, with a deep angular depression anteriorly, the sides of which

converge to meet just in front of a well-marked fovea between the eyes; the lateral

impressions are elongate and extend as far as the insertion of the antenne, being thus

in front very near to the median depression, and giving the latter somewhat the

appearance of being limited by a carina on each side anteriorly. The thorax is

moderately long, subcylindrical, though a little narrowed in front, with only a few

punctures. Klytra with series of rather large punctures which are moderately

approximate. Six specimens.

This insect was named FE. convexus, Schonh., in Sallé’s collection, but the next

species agrees better with Boheman’s description. . reversus is closely allied to

E. convexus, however, and differs by the peculiar depression on the rostrum, and also

by having the thorax less rugose and the punctures on the elytra larger. E. frontere,

which has a similar depression on the rostrum, is very different in shape.

19, Epicerus convexus.

Epicerus convexus, Boh. in Schonh. Gen. Cure. vi. 2, p. 281°.

Hab. Mexico1, Juquila, Panistlahuaca, Etla (Sallé), Jalapa, Oaxaca (Hoge).

The specimens I assign to this species are in all twelve in number, there being only

two or three from each locality ; they vary a great deal, so as to leave some doubt as

to their all belonging to one species. Two or three agree satisfactorily with Boheman’s

description, having only a slight depression on the rostrum, but in others the depres-

sion is larger. ‘The pallid colour of the sides also varies, and in some specimens is not

conspicuous, while in others it is nearly pure white, and in one or two is white,

delicately tinted with green. Such examples were labelled Hpicwrus marginalis,

Chevr., in Sallé’s collection.

A typical example of E. convexus, communicated from Schénherr’s collection by

Dr. Aurivillius, is rather larger and more elongate than any of our series, and has the

rostrum still less distinctly impressed ; but I consider it to be only an extreme form of

the same species as our series.

20. Epicerus sturmi, sp. n.

Minus elongatus, ovalis, convexus, niger, griseo-squamosus, lateribus corporeque inferins albidis; rostro

profunde impresso ; prothorace conico, subsequali; elytris seriatim remote punctatis.

Long. 93 millim.

Hab. Mexico (Sallé).

This species is allied to E. convexus and E. reversus, but is considerably shorter in

form; the rostrum is short, broadly and deeply impressed in front, with a minute

fovea between the eyes. The thorax is gradually narrowed from the base to the front,

with a coarse but indistinct punctuation, and a feeble longitudinal depression, not

extending to the base, on the middle. The elytra have regular series of remote

punctures, distinct at the base but extremely minute behind; the squamosity is rather

irregularly distributed, so as to give a slight appearance of two rather darker fascize

across the middle.

Of E. sturmi we have obtained only two old examples, without special locality, from

Sallé’s collection; one of them was formerly in Sturm’s collection and is labelled

“ Barynotus obliquefasciatus, mihi,” in that naturalist’s writing. It is not very likely

to be mistaken for any other of our species except 2. reversus, which is of much more

elongate form. LE. frontere has also a deep impression on the front of the rostrum,

but it is a larger and broader insect, with less conical, more coarsely sculptured thorax.

The two specimens of H. s¢twrmi are no doubt of the female sex.

21. Epicerus championi, sp.n. (Tab. V. fig. 7.)

Angustulus, griseo-squamosus; prothorace inequali, fortiter subobsolete punctato; elytris transversim

subundulatim impressis.

Long. 9 millim.

Hab. GuatEMALA, San Geronimo (Champion).

Rostrum rather short, punctate and squamose, impressed along the middle and

foveolate at the summit of the impression; lateral impressions broad and placed much

on the front aspect. ‘Thorax subconical, but with a slight constriction at the sides

behind; the surface with coarse, very vague, rather regularly distributed impressions.

Elytra slightly constricted at the base, with series of impressions that are connected

trausversely so as to form undulatory grooves. The suture of the elytra is in the

female a little more prominent at the commencement of the apical declivity.

EPICZRUS. 115

There is no difficulty in distinguishing this insect, the vague depressions seen in other

species in connection with the punctuation being in EZ. championi unusually developed.

A small series was procured.

22. Epicerus tenuis, sp. n.

Gracilis, niger, griseo-squamosus ; rostro anterius in medio leviter impresso ; prothorace subcylindrico, ineequali ;

elytris seriatim remote sat fortiter pu nctatis.

Long. 8-9 millim.

Hab. Muxico, Xautipa and Chilpancingo in Guerrero (4. H. Smith).

Rostrum in the male with a distinct short longitudinal depression on the middle, in

the female almost flat ; a distinct fovea between the eyes. Thorax very little broader

behind, the surface covered with vague impressions, and with an obscure depression

along the middle. Elytra with regular series of punctures, which towards the suture

in front are larger and foveiform. Hight specimens.

This is one of the most slender insects of the genus, and the sexual distinctions are

comparatively slight, the female being, however, rather broader and more convex.

The next two species approach L. tenuis very closely, but the thorax in them is less

rugose.

23. Epicerus pedestris, sp. n.

Angustulus, niger, griseo-squamosus, fere concolor; prothorace impressionibus paucis subinequali; elytris

seriatim remote subtiliter foveolatis.

Long. 8-9 millim.

Hab. GuatEMata, Cerro Zunil, San Gerénimo (Champion).

Rostrum similar in the two sexes, nearly flat and unimpressed, with a small puncti-

form fovea between the eyes. Thorax conico-cylindrical, not much narrowed in front,

the surface shining black (but covered with minute scales) and rendered slightly

uneven by a few vague impressions ; in the male with a slight transverse constriction

immediately before the base. Elytra with regular series of moderately large rather

distant punctures, the surface slightly depressed round each puncture; in the male

there is a distinct constriction just behind the base.

Three examples were found at Cerro Zunil, one at San Gerdénimo; the specimen

from the latter locality differs considerably in outline and a little in colour, and may

perhaps prove to belong to a distinct species.

24. Epicerus capetillensis, sp. x.

This insect is very closely allied to E. pedestris, but is distinguished by the fact that

the vague impressions on the thorax are nearly absent, the serial punctures on the elytra

are not so large, and that there is less difference between the sexes; the male differing

from the female chiefly in being smaller and more slender, with the prothorax a little

more conical. In both sexes the rostrum is flat and nearly unimpressed, and there isa

small though very distinct fovea between the eyes. About twenty examples.

Long. 8 millim.

Hab. Mexico, Oaxaca (fége).

This is a narrow Epicwrus very densely covered with squalid squamosity in a

uniform manner, except that there is an obscure transverse darker fascia across the

middle. Rostrum densely squamose, feebly impressed on the front, with a fovea

between the eyes. Thorax conico-cylindrical, not at all constricted near the base; the

surface not uneven, but with a few distant punctures concealed by the squamosity.

Elytra with remarkably definite deep foveiform punctures placed in very regular series.

Three specimens.

This species is perhaps best placed near HE. pedestris, compared with which it is

found to be more continuous in outline, and more uniformly covered with darker squa-

mosity ; the eyes are smaller, the thorax less impressed, and the legs smaller.

26. Epicerus bicolor, sp. n.

Niger, capite prothoraceque parcius subtiliter squamosis, hoc impressionibus paucis subinzquali ; elytris fusco-

Hab. Mexico, Tapachula in Chiapas (f6ge); GuatTeMALa, San Isidro, Las Mercedes,

Volcan de Atitlan (Champton).

Rostrum flat, not at all impressed along the middle, with a minute punctiform fovea

between the eyes. Thorax rather short, with only a very few impressions on it.

Elytra with the upper surface covered with dark fuscous scales, the sides nearly white ;

the impressed remote punctures of the series are fine. Many specimens.

When quite fresh, the rostrum and thorax of this species are covered with a delicate

squamosity which is apparently very easily abraded ; in such specimens the squamosity

of the elytra almost entirely conceals the sculpture. There is not much difference .

between the sexes, except that the female is larger and more convex than the male.

Epicerus griseus, Boh. in Schénh. Gen. Cure. vi. 2, p. 2827.

Hab. Mexico !, Playa Vicente, Orizaba, Cordova (Sallé), Jalapa (Hoge).

We have received seven examples of this species; it is distinguished from FE. sphe-

rotdes chiefly by the broad depression on the front of the rostrum, and also is rather

larger in size. | |

I am by no means sure as to the distinctions between Boheman’s EF. griseus and

E. spheroides; the small series of the two we have received are variable in respect of

the characters mentioned by the Swedish writer. I have therefore arbitrarily divided

our examples, as above stated, until a larger number of specimens shall have been

obtained, so as to allow the sexes to be distinguished, and thus facilitate the solution

of the question as to whether EZ. griseus and E. spheroides may not be the sexes of one

variable species. An example of EH. griseus communicated by Dr. Aurivillius from

Schénherr’s collection agrees with our examples.

28. Epicerus spheroides.

Epicerus spheroides, Boh. in Schénh. Gen. Cure. vi. 2, p. 2837.

Hab. Mexico 1, Oaxaca (Hége), Cordova, Orizaba, Playa Vicente (Sallé).

I refer to this species a dozen examples which agree moderately well with Bohe-

man’s description, and with three specimens in my own collection determined by the

late M. Jekel as being E. sphaeroides. We have also received some half dozen

specimens that are very variable as regards the characters supposed to be distinctive of

E. spheroides and £. griseus. The example of E. sphwroides communicated by

Dr. Aurivillius from Schonherr’s collection I cannot distinguish from EF. griseus; but it

is probable that other examples in his collection may prove to have the rostrum

unimpressed, as stated in the description.

29. Epicerus oscillator, sp.n. (Tab. V. fig. 8.)

Convexus, niger, griseo-squamosus; prothorace conico-cylindrico, obsolete inzquali, haud punctato; elytris

minus fortiter seriatim punctatis.

Long. 74-10 millim.

Hab. Mexico, Capulalpam (Sa//é).

Rostrum short and broad, in front indistinctly and broadly impressed; scrobes short,

rather broader and more indefinite behind than is normal in Epicwrus. Thorax

narrowed in front, not constricted behind, the surface very slightly uneven but without

channel or punctures. Elytra rather short, much elevated, with somewhat indistinct

series of punctures.

This insect resembles the shorter and more strongly-scaled varieties of E. mexicanus,

E. nebulosus, and E. sqguamosus. It has the scrobes shorter and rather broader and

118 RHYNCHOPHORA.

more indefinite behind, so that it may be doubted whether it should remain in

Epicerus ; but as E. squamosus to some extent connects it with # meaicanus, the

typical species of the genus, I think it would be wrong to separate it at present. The

truncation of the tip of the hind tibia is almost completely absent in Z. oscillator, but

this is also the case with some other species of Epicwrus.

We have received only three examples of this species. It apparently varies in a

similar manner to Z. mexicanus, the sculpture and squamosity being a little dissimilar

in each of the examples. The male is much smaller than the female, but exhibits

scarcely any difference in the shape of the elytra.

30. Epicerus minor, sp. n. (Tab. V. fig. 9.)

Brevis, convexus, niger, squamosus, hispidus, subvariegatus; antennis rufis; rostro brevi, fere squali, fronte

fovea elongata munita.

Long. 53 millim.

Hab. Guaremata, San Gerénimo (Champion).

Rostrum very short, not broader in front, covered with scales, the nasal plate very

prominent, polished, the forehead with a deep elongate fovea; the eyes large, not

prominent. Thorax short, much rounded at the sides, deeply and coarsely punctate,

covered with griseous scales, the basal margin distinct. Elytra densely squamose, the

squamosity griseous, whitish, and fuscous, but not forming a definite pattern; with

regular series of fine punctures, the interstices very broad but scarcely perceptibly

convex. One specimen.

I can detect no good character for distinguishing this insect from Hpicerus, though

the apex of the hind tibia is so simple that Lacordaire would no doubt have considered

the corbels to be open. There is, however, much variety in Epicerus as to this

character, and even in £. minor there is visible a slight incrassation of the apical face

of the outer lamina, so that I consider the corbels to be cavernous in a rudimentary

degree. The insect bears a good deal of resemblance to Epagrius pumilus and LE. levi-

nasus, but they have broader scrobes.

the base, densely squamose, and furnished with very regular series of deep, moderately

large punctures. Under surface squamose. One specimen.

There is no other species of the genus at all like this one ; indeed, in appearance it

more resembles Tosastes globipennis and T. humeralis.

32. Epicerus durangoensis, sp.n. (Tab. V. fig. 11.)

Long. 7 millim.

Hab. Mexico, Durango city (Hoge).

Antenne with moderately long slender club, which is black in colour. Rostrum

oblong, densely squamose, very feebly canaliculate along the middle, with a deep,

moderately long frontal channel. Thorax 2 millim. long, slightly transverse, densely

covered with grey and brown squamosity, which conceals the rugose surface; there is

a shallow and obsolete channel along the middle. Elytra covered with grey and pale

brown squamosity, the squamosity much mottled, but not forming any definite pattern ;

with quite regular series of rather fine deep punctures, and with a recumbent setosity

on the interstices. Legs densely covered with squamosity.

Rostrum short and broad, densely punctate, squamose ; eyes moderately convex ;

forehead with a very definite fine channel, nearly as long as the length of the eye.

Thorax very strongly transverse, a little narrowed from the middle to the front, without

rugosities or punctuation, and with only an obsolete interrupted median channel; the

surface is squamose, and there is a fine basal margin. Elytra densely squamose, the

squamosity scarcely variegate, covering regular series of rather fine punctures. Four

specimens.

This species is twice as large as Bradyrhynchus toluce, and has the rostrum flat on

the anterior aspect; it should be readily identified by the fine but comparatively

elongate and definite channel on the forehead.

I cannot distinguish Z. ravidus from E. aurifer, which I look upon as a variable

species like several others of the genus. The type of £. aurifer sent by Dr. Aurivillius

from Schénherr’s collection is an example of the most coarsely sculptured form of the

species as known to me. I have not seen any typical example of Z. ravidus, which was

described from Germar’s collection, but I have very little doubt it will prove to be the

more thickly scaled and finely punctured form of this species.

Rostrum somewhat closely punctate, broadly but not deeply impressed on the

middle, with an obsolete channel (rather more distinct in the female than in the male)

in the depression; lateral impression moderately large; the fovea on the forehead

distinct. ‘Thorax elongate, subconical, finely punctate, very sparingly squamose, with a

vague depression on the middle interrupted just on the disc. Elytra with series of

very large punctures, the alternate interstices but little raised, the one proceeding from

the shoulder is, however, quite distinct, and outside it, near the shoulder, there is an

accumulation of pallid scales. ‘The squamosity is less scanty on the apical parts of the

elytra; and the under surface is almost covered with scales. Two specimens.

This species is similar to some of the varieties of &. aurifer; but it has a much

longer thorax, and larger punctures on the elytra.

somewhat depressed along the middle; the depression in the male broad, shallow, and

scarcely canaliculate, in the female more elongate, narrow, and vague, but very distinctly

canaliculate; lateral impression short, placed near the eye; a fovea on the forehead.

Thorax conico-cylindrical, nearly bare on the upper aspect, squamose on the flanks ;

sparingly and finely punctate, very feebly longitudinally depressed along the centre,

the depression interrupted in front of the middle and not reaching the base. Elytra

narrow and subcompressed, with a series composed of paired, nearly confluent, coarse

punctures or fovee near the suture, the interstice between the two punctures forming

each pair very little elevated; outside them a more elevated interstice, and then outside

this the space occupied by the next pair of series covered with a pallid sulphurous-

yellow squamosity; the lower part of the sides feebly squamose.

This species will, 1 think, be readily recognized by the yellow lateral stripe. ‘There

is apparently but little difference between the sexes, except as regards the depression

on the rostrum.

Angustus, valde convexus, niger, nitidus, subnudus ; elytro singulo posterius ad latus vitta obliqua albida.

Long. 9 millim. .

Hab. Mexico (Sallé, ex coll. Sturm).

Rostrum nearly flat in front, rather short; lateral impressions small; frontal fovea

obsolete. Thorax conico-cylindrical, shining black, finely punctate, almost destitute of

scales, vaguely impressed along the middle, the impression not extending to the base or

apex. lytra with series of moderately large, rather widely separated punctures; the

third interstice not visibly elevated, the fifth distinctly so; the surface black and some-

what shining, only very slightly squamose or setose, but with a more or less distinct

interrupted vitta of white squamosity extending from near the middle of the side

obliquely backwards and inwards to near the suture.

This insect is allied to H. lateralis; but, in addition to the different stripe on the

elytra, the rostrum is nearly unimpressed along the middle, and the fovez or punctures

on the elytra are much smaller. ‘The species is described from two specimens from

Sturm’s collection labelled “ Hypsonotus decoratus, Sturm;” one of the two is more

slender and elongate than the other, so that they are probably of different sex.

88. Epicerus oculatus, sp. n. (Tab. V. fig. 14, ¢.)

Griseo-squamosus ; rostro brevi, ad apicem profunde curvatim depresso; prothorace medio vage sulcato; elytris

seriatim multipunctatis.

Long. 12 millim.

Hab. Mexico, Oaxaca (Sal/é).

Rostrum short and broad; the clypeal depression with elevated margins and surrounded

behind by a well-marked curvate depression ; the sides of the front of the rostrum a little

elevated and prolonged ; the middle of the front of the rostrum broadly deplanate and

slightly depressed; the lateral depressions vague; the frontal fovea small; the eyes

moderately convex, nearly circular ; the surface punctate, but little squamose. Thorax

a little narrowed in front, finely punctate, the dorsal surface feebly squamose, the flanks

more densely so, on the middle a very vague longitudinal depression. Elytra with series

of rather small punctures, the interstices similar (there being no trace of any greater

elevation of the alternate intervals), just perceptibly convex, the sculpture greatly con-

cealed by a sordid squamosity.

This species is distinguished from the other Epzcewri by the somewhat aberrarit

structure of the front of the rostrum. Only two specimens have been received ; they

are no doubt the sexes, as they exhibit a great disparity in the breadth of the body.

Group 3.—Thorax without the peculiar form and sculpture of Group 1; the rostrum

usually a little broader towards the tip, with the pterygia exposed. (Species 39-52.)

This group contains also a considerable variety of forms; as a rule, the rostrum is

perceptibly broader at the tip and the pterygia a little more conspicuous than in

group 2; usually, too, the scrobes are a little broader.

39. Epicerus squamosus, sp. n.

Minus convexus, niger, ubique pallide griseo-squamosus ; prothorace leviter inzequali, basi subconstricto ; elytris

Long. 9-10 millim.

Hab. Mexico, Puebla (Sad/é).

Rostrum moderately long, parallel, scarcely impressed on the middle, with a small

fovea between the eyes; antenne with the first joint of the funiculus rather longer than

usual, a little longer than the second. Thorax a little narrower in front than behind,

and slightly constricted at the base; the surface very feebly rugose, with no distinct

punctures, and only traces of a depression along the middle. Elytra with series of

moderately fine punctures, the interstices of which are not completely flat. Five

specimens.

This species appears to a considerable extent to connect the three groups. The

surface is uniformly covered with adpressed pallid scales, each scale being isolated from

its neighbours. There is a very fine, indistinct basal margin to the thorax.

Rostrum closely punctate, squamose and setose, with a broad depression along the

middle and a rather obscure fovea above it. ‘Thorax narrower in front than behind,

considerably constricted at the base, the basal margin raised, fine and definite; the

surface slightly uneven, with a few irregular depressions of different sizes and also

minutely punctate, but this punctuation concealed by a scale placed in each puncture ;

regular series of distant punctures somewhat concealed by the closely-adpressed scales ;

and also with a few suberect squamiform sete that are quite conspicuous behind, but

in front are much shorter and differ little from the other scales. One specimen.

This is not closely allied to any other species of the genus, though it to a considerable

extent connects L. pyriformis and LE. scutellaris; but the former has no distinct basal

margin to the thorax, und the latter scarcely any squamosity on the elytra.

Long. 104 millim.

Hab. Mexico, ‘Toluca (Sa//é).

This species is distinguished by the fact that the scutellum is quite visible between

the bases of the wing-cases in the shape of a small transverse process; the sculpture of

the rostrum and thorax, too, is peculiar, consisting of a mixture of fine and larger

punctures. Rostrum rather short, densely punctured, sparingly setose, with a deep

fovea on the forehead, a very vague broad depression along the middle, and a short

oval impression on each side; antenne not elongate, the second joint of the funiculus

slightly longer than the first. Thorax rather elongate, impressed with numerous fine,

and more scanty large, punctures; along the middle of the basal part with a fine

channel formed by confluent punctures. Elytra elongate, with regular series of rather

fine punctures, the interstices bare. ‘Two specimens.

The male has the front inner part of the apical portion of the hind tibia densely

covered with pallid pubescence.

42. Epicerus insolitus, sp. n. (Tab. V. fig. 15.)

Hab. Mexico, Zacualtipan (Hoge).

Rostrum densely punctate, armed sparingly with white sete, with a broad shallow

depression on the middle and a small deep fovea on the forehead. Thorax 3 millim. long,

and in its greatest width scarcely so broad as this, with a narrow irregular sulcus along

the middle and a few large punctures or impressions distributed over the basal half.

Elytra elongate, curved at the sides and a good deal narrowed at the shoulders, emar-

ginate at the base—the base of the thorax not well fitted in the middle to the base of

the elytra; the shoulders slightly overlapping each side of the base of the thorax; the

punctures are small and not deep, and the interstices have no trace of carination.

Hab. Mexico, in the pine-forest of Popocatepetl (Godman).

Rostrum with the pterygia but little prominent; with a broad, shallow, median

impression, a very deep front fovea, and on each side of the front a deep oval impres-

sion; eyes rather large, subconvex ; antenne slender and elongate, the second joint of

the scape a little longer than the first. Thorax elongate, covered with vague, coarse,

rugose depressions, which form a very indistinct groove along the middle; it is slightly

narrower in front than at the base, and the basal margin projects a little laterally, the

upper surface at the base being rather abruptly distinguished from the sides. Hlytra

long and narrow, subparallel, with series of large, rather closely placed, deep punctures.

Depressions of the under surface of the rostrum very deep, the supports of the mandi-

bular pieces unusually elongate. ‘Two specimens.

This is a remarkably distinct species, in some respects allied to the £. vets group, in

others to #. mexicanus.

Long. 11 millim.

Hab. Mexico, Oaxaca (Hége).

Rostrum widened at the apex, the pterygia distinctly projecting laterally; on the

middle with a broad deep depression, the frontal fovea scarcely visible; on each side of

the front a short additional impression, and another depression adjoining the front of

the eye; the surface bearing scanty obsolete scales, each of these placed in a very

shallow puncture, which it exactly fills. ‘Thorax rather depressed above, and with a

vague depression along the middle not reaching the front or the base, slightly narrower

in front than at the base; the surface appearing naked, but covered with imbedded

scales, with scarcely any sculpture, and remarkably even, except for the median groove.

Elytra covered with scales that are less obsolete than those on the anterior parts; a little

broader at the sides from the base to behind the middle, with rather regular series of

large impressions. Flanks and under surface covered with a squalid squamosity. One

specimen of each sex.

It is very difficult to assign a satisfactory place in the genus to this species. By the

EPICERUS. 125

form of the rostrum it belongs to the EZ. vilis group ; but in the sculpture of the thorax

and the general form it departs widely from the members of that group. ‘The second

joint of the scape, though not elongate, is distinctly longer than the first. The female

is considerably broader than the male, and the declivity of the elytra is rather

longer.

ITab. Mexico, Parada, Cinco Sefiores (Sai/é).

Rostrum densely punctate, on each side of the upper face with an elongate depression

somewhat interrupted near the front; along the middle with a longitudinal depression,

which is deep and abruptly limited in front, so as to form a sort of fovea; on the fore-

head with a small, quite distinct fovea. Thorax much narrowed from the base to the

front, depressed along the middle, and with two punctures in the depression ; the

surface, like that of the head, is black, but is nevertheless really covered by scales that

appear to be very delicate and closely adherent to it. Elytra rather broad, each

with three raised carine, and between each two of these with two series of coarse,

nearly confluent impressions; covered with a squamosity that looks like dirt. Four

specimens.

This is very distinct from the species near which I place it on account of the strong

carination of the alternate interstices.

46. Epicerus hegei, sp. n.

Hab. Mexico, Salazar (£Hége).

This species, of which only a single worn example of the female sex has been

obtained, was at first placed by me as aslight variety of & scutellaris; but on exami-

nation it appears that the scutellum is normal, and not exposed asin £. scuteliaris.

Moreover, the channel on the posterior part of the thorax is not to be detected, and

the hind margin of the thorax is conspicuously raised. ‘The elytra, too, in their poste-

rior part are very distinctly setigerous, the sete being fine, short, quite erect hairs,

whereas in E. scutellaris only a few short depressed setee can be detected. ‘These

characters leave no doubt that the two are distinct, notwithstanding their great

general resemblance.

Rostrum canaliculate along the middle, with a small fovea at the summit of the

punctate. Thorax elongate, rounded at the sides, with the greatest width in front of

the middle; the surface rendered very uneven by coarse punctures, and also with a

minute interstitial punctuation, somewhat shining, with a vague depression along the

middle. Elytra elongate and narrow, black, but rendered somewhat dull by a thin

adherent squamosity ; with regular series of rather large distant punctures, and on the

declivous portion with a very scanty setosity. Legs elongate. Six specimens.

There is not much difference between the sexes of this species, the female having the

elytra only a little broader than the male, and the suture behind more prominent. I

have examined a type from Chevvrolat’s collection communicated by Dr. Aurivillius.

Hab. Mexico, Las Vigas (fége).

This is one of the species that, though covered with scales, still appears quite black.

It is closely allied to L. tristis, but is readily distinguished by the much smaller, more

numerous punctures in the series of the elytra. The rostrum is deeply sulcate along

the middle in the male, more broadly and less deeply so in the female; the lateral

impressions are elongate and distinct; and there is a rather large fovea between the

eyes. Thorax elongate, very coarsely and deeply punctate, a little flattened and

impressed along the middle in the male, but scarcely at all so in the female. Elytra

quite dull, furnished with very regular series of rather fine punctures, with a short

minute serial setosity on the interstices.

Five specimens have been obtained of this species. There is a good deal of difference

between the sexes, the female being a much broader and more obese insect than the

male and having the apical portion of the elytra more elongate and perpendicular.

Calderas, Duefas (Champion).

This is a considerably smaller insect than LE. tristis, with a rather shorter thorax and

much coarser setosity, the latter not being confined to the elytral declivity but evident

over the whole surface; the antenne are only about half as thick, being unusually

slender. ‘The female has the elytra broader and shorter, more abruptly narrowed

behind, and with the suture before the apex more prominent.

This species is very variable, if all the specimens I refer to it are really conspecific.

The length varies from a little less than 8 to rather more than 10 millim.; the

clothing, sculpture, and the sexual distinctions in the shape of the body also vary much.

Possibly there may be more than one species amongst these specimens, but if so it will

be no easy task to discriminate them. I have examined about twenty-five examples,

including a typical specimen from the Schénherrian collection.

joint of the funiculus very long. Thorax elongate, a little narrowed in front, the surface

not distinctly punctured but with vague coarse impressions concealed by the squamosity.

Elytra at the base only as broad as the base of the thorax, but becoming broader to

behind the middle, and in the female very broad, furnished with regular series of coarse

depressions, densely squamose, and with scanty, short, coarse sete.

This insect is very closely allied to £. carinatus, but is larger, and has the elytra

much broader—especially in the female,—and the rostrum broader and less impressed.

millim. long and fully 2 millim. broad, a little rounded at the sides, the surface

bearing large deep punctures which are much obscured by the squamosity. Elytra

short, abruptly declivous behind, bearing series of deep, rather large punctures; covered

with squamosity and with two darker irregular transverse bands, one just in front of

the middle, the second behind it.

This does not seem to vary quite so much as some of the other species of the genus,

but there is a considerable difference between the sexes, the female being broader and

the prominence on the suture behind remarkably abrupt. About two dozen examples

were obtained, all from the Pacific slope. |

a setose squamosity. Thorax elongate, narrowed in front, the surface rendered uneven

by coarse, very shallow depressions, the disc slightly deplanate ; closely and finely

punctate and clothed with depressed sete. Elytra with series of moderately large,

distant, shallow punctures, clothed with thin, closely adherent scales, and bearing also

a scanty, very short squamosity. Under surface setose; the first ventral suture slightly

arcuate; the male with the base of the ventral surface rather deeply depressed. —

This species is remarkable on account of the great difference in the form of the base

of the elytra in the sexes. Only one male and two female examples of it were —

obtained.

Epiceri proxime affinis ; differt scrobibus latioribus, tibiarum posticarum corbellis subcavernosis.

The species placed in this genus have the scrobes broader than in Hpicerus, and

usually their terminal portion is less definite, the upper border more especially being

less sharply defined.

EPAGRIUS. 129

This is the genus which Lacordaire referred to 1, and—speaking of one of its species

—said that it must be separated from Epicwrus on account of the posterior corbels

being open. The posterior corbels I consider, however, to be feebly cavernous, and I

think this difference alone would not be sufficient to substantiate the generic separation

proposed. I find, however, that the scrobes also are considerably broader in Hpagrius

than they are in Hpicwrus, and the two characters taken together separate the genera

fairly well. There is, however, considerable variety in the genus as to each of the

characters—LHpagrius albosquamosus, for instance, having the cavernous corbels as

distinctly developed as they are in some Epiceri,—so that the location of some of the

species in the genus is not quite satisfactory.

As regards the synonymy it should be remarked that Lacordaire considered

Graphorhinus to cousist of G. operculatus and G. vadosus, Say; the latter species was,

however, unknown to him and he drew his characters from the former. Horn has

since pointed out that these characters do not agree with those of the latter species—

viz. G. vadosus, Say ; and as this is the type of Graphorhinus, Say, another name must

be found for the Graphorhinus as known to Lacordaire. Hpagrius having been founded

by Schonherr on a species—as I believe—of the present genus, the name appears to be

available, although it was treated by Lacordaire as merely a synonym of Graphorhinus.

Unfortunately I have not been able to see an example of EH. nubilosus, on which

Schonherr founded ELpagrius, so that my application of the name may possibly prove

to be erroneous. |

For the purposes of determining the species the genus may be considered to consist

of seven groups, Viz. :—

1. Obese, comparatively large insects with a more or less definite sulcus along the middle of the

thorax. Species 1-5.

2. Smaller insects without groove, but with some punctures placed in front of one another on

the middle of the thorax. Species 6-8.

3. Insects of moderate or large size, with a broad impression or deplanation on the middle of the

thorax. Species 9-15.

4, An insect of rather large size, without depression or channel on the thorax, but with the

scutellum distinctly visible at the base of the elytral suture. Species 16. Pais

5. Quite small insects, squamose, but with the front of the rostrum exhibiting a large, angular,

glabrous space. Species 17, 18.

6. Individuals of medium size, with the rostrum broader towards the tip; very coarsely

sculptured ; scape much clothed. Species 19.

7. Size very large. Species 20, 21.

Upper surface much covered with pearly scales. Rostrum short, with a well-marked

punctiform fovea on the forehead, a channel along the middle reaching from the apex

to near the fovea, but obsolete in its posterior part, and also with a rather small oblong

depression on each side of the upper surface. ‘Thorax short, 24 millim. long, and

about 32 millim. broad on the middle, with a broad depression along the centre, which

sometimes has a few coarse punctures in it; the middle is dark in colour, except that

there are usually some pearly scales along the depression ; on each side there is a rather

vague vitta of similar scales; there are usually one or two vague depressions placed on

each side at about half the length. Elytra short and broad, much covered with pearly

scales, but with dark marks on the alternate interstices; these darker stripes have

irregular edges—the inner stripe is elongate, extending beyond the middle, and the next

one to it is still longer; on the outer interstices the dark marks are smaller; the

punctures of the series are very definite, but not variolose; and the interstices are not

at all convex. Under surface black, with some scanty pale scales. Legs short;

anterior tibie not curvate externally.

This species, on the upper surface, is entirely covered with scales: the dark marks

that look like denuded spaces being actually covered with dark, very thin scales, that

adhere very closely to the surface. It is possible, I think, that the pallid scales may

change colour during the life of the insect, either by friction or staining or both; if

this be the case, but little importance can be attached to the colour of this insect and

its allies.

Hoge has sent a series of nearly thirty specimens from Las Vigas; these appear to

be in very fresh condition, and vary but little, even in colour. The examples from

other localities are few, and none of them are so prettily and definitely coloured, the

pale scales being deficient in quantity and irregularly distributed. This species may be

known from its allies, however, independently of colour, by the short broad form, and

the small size of the punctures on the elytra. JI can find no external sexual

distinctions.

I have examined an authentic example of the species from Schonherr’s collection.

EPAGRIUS. 131

This insect is very closely allied to E. operculatus, but is entirely dark in colour;

this point is perhaps of little importance by itself, but it is confirmed by the impressed

punctures on the elytra being larger, and the interstices not quite so flat. The surface

has a peculiar lustre caused by closely adherent scales of dark colour, like those on the

darker parts of E. operculatus. The mesosternal interval between the middle legs

seems to be slightly greater than it is in E£. operculatus.

Closely allied to H. operculatus, but rather larger and more elongate, the surface

more zneous, and the pallid scales quite irregularly distributed. The punctures on

the elytra are rather small as in £. operculatus. The hind margin of the second

ventral segment is broadly and abruptly perpendicular, and it appears to be slightly

raised, giving rise to the appearance of a transverse impression across the segment

near the hind margin.

Four specimens; the one from Guanajuato differs from the others in having the

interstices of the elytra slightly convex.

This species also is closely allied to £. operculatus, but is distinguished from all the

allies by the comparatively more elongate thorax and the considerable curvature of the

front legs. The median and lateral impressions on the rostrum are not very deep; the

frontal fovea is moderately large. The thorax is 3 millim. long, and about 34 millim.

rately large, the interstices not convex. The front tibiz are much curved at the apex ;

the hind tibiz are also somewhat curvate and bear white hair on the inner face tuwards

the extremity.

Six specimens.

5. Epagrius variolosus, sp. n.

Brevis, convexus, niger, subsenescens, squamulis pallidis, parcis subvariegatus ; rostro medio late impresso ;

elytris punctis seriatis fere variolosis impressis.

Long. 11 millim.

Hab. Mexico, Amula and Xucumanatlan, both in Guerrero (H. H. Smith).

In form similar to HL. eperculatus, but with a short broad impression on the rostrum

and with larger punctures on the elytra. Antenne with slender, quite black, club.

Rostrum short and broad, with a broad, deep, short impression on the middle, this

impression limited in front by a sharply marked elevation separating it from the

apical angular depression; on each side there is a rather deep, short depression, and on

the forehead a moderately large fovea. Thorax short and broad, 23 millim. long by

32 millim. broad, a little narrowed in front, the disc depressed and with a few large

punctures and an obsolete canaliculation in the depression, two or three obsolete

punctures on each side. Elytra covered with scales which are separated by rather large

intervals, these scales to some extent pallid and disposed so as to indicate very vaguely

two transverse irregular dark marks, one across the middle, and another bctween

this and the extremity ; they bear very deep punctures, placed in series, and separated

by somewhat convex spaces. Legs short, with much pallid setosity.

Two specimens.

Group 2.

6. Hpagrius parada@, sp.n. (Tab. V. fig. 20.)

Niger, subsenescens, nitidus, squamulis pallidis variegatus; rostro crasso, profundius tri-impresso ; prothorace

disco foveolis magnis impresso; elytris punetis seriatis subvariolosis impressis.

Long. 74-83 millim.

Hab. Muxico, Parada (Sallé).

Antenne with much white setosity, extending quite to the base of the moderately

broad club, the latter black. Rostrum broad and very short, nitid, finely punctate,

with only a very minute punctiform fovea on the forehead, but in front of the eyes

with three very deep impressions—the lateral one on each side unusually deep, the

median one remarkably broad and abruptly terminated in front in a rounded manner.

Thorax short and broad, slightly narrowed in front, at the sides covered with pale

squamosity, on the dise with some large punctures or depressions, two of which form

along the middle an interrupted sulcus abbreviated behind. Elytra with series of

rather large, moderately deep punctures, separated by somewhat convex interstices, and

with a pallid squamosity arranged so as to leave a dark mark behind the middle, which

mark is dilated and angular on the suture behind. Legs short.

We have received only two specimens of this distinct species. They are probably

male and female, the latter being much the broader.

EPAGRIUS. 133

7. Epagrius hystriculus, sp. n.

Niger, subzenescens, nitidus, squamulis pallidis variegatus ; rostro crasso, tri-impresso, impressione mediana

latissima ; prothorace fortiter parum argute punctato ; elytris seriatim punctatis, interstitiis biseriatim

setosellis.

Long. 74 millim.

Hab. Mexico, Yolos (Sallé).

Rostrum short and broad, with a very deep lateral impression on each side, and a

vague, very broad median one, this latter only sharply limited in front; the space

between the eyes is transversely very slightly depressed, and bears a small fovea on the

middle; eyes rather convex. ‘Thorax nearly as long as broad, but little narrowed in

front, with numerous large but vague punctures ; covered with pallid squamosity at the

sides, but only very scantily so on the upper surface, which is somewhat brassy. Elytra

brassy, the sides narrowly, the apex broadly covered with pale squamosity, and with a

pallid mark of this nature curving inwards from the shoulders ; bearing suberect scanty

setee on the somewhat convex interstices between the large but rather indefinite punc-

tures. Under surface covered with pale squamosity.

Distinguished amongst its allies by the setosity of the upper surface. Only two

specimens have been received.

8. Epagrius hispidus, sp. n. (Tab. V. fig. 21.)

Minor, angustus, niger, squamosus, setis erectis tenuibus adspersus, elytris albido fuscoque variegatis.

Long. 52 millim.

Hab. Mexico, Ventanas in Durango (Hége).

Antenne stout, the second joint of the scape scarcely so long as the first; club

elongate, as long as the three preceding joints together. Rostrum broad and short, with

two slightly elevated carine, diverging towards the front, the space between them very

slightly depressed, and forming at the summit a longitudinal depression or channel.

Eyes rather prominent. Thorax not transverse, subcylindric, very little narrowed in

front, almost without sculpture but covered with scales, with a small, short depression on

the disc. Elytra with regular series of closely-placed, elongate, deep but fine punctures,

and with fine slender erect sete, scattered amongst the large round scales with which

they are covered ; these scales are of white and of tawny colours disposed so as to form

a vague pattern, the most definite part of which is a white band just behind the middle.

One specimen.

This is a most difficult insect to place. It does not at all resemble any other species

of this genus, but in appearance suggests a small Epice@rus; the scrobes are, however,

too broad and too vague behind for that genus.

Group 3.

9. Epagrius constans, sp. n. (Tab. V. fig. 22, 3 .)

Nigerrimus, subopacus, nudus ; prothorace dorso leviter impresso, punctis impressis paucis irregulariter sitis ;

elytris punctis magnis, profundis, seriatim dispositis, ornatis.

Long. 10-12 millim.

Hab. Guatemata, Totonicapam 8500 to 10,500 feet (Champion).

Rostrum much broader towards the extremity, nearly flat, finely punctate, alutaceous,

dull, the lateral impressions wanting, the frontal fovea minute but distinct. Thorax

very coarsely punctate at the sides, the disc slightly depressed, the depression separated

from each side by a broad slight elevation which is free from punctuation; in the

depression there are twelve or fifteen punctures irregularly arranged ; basal margin

very distinct. Elytra with rows of very sharply defined, deep, rather large punctures ;

the surface between the punctures is almost destitute of sculpture, and there is not

the slightest elevation of any of the interstices.

Mr. Champion obtained a series of about 100 examples of this species, from beneath

stones on an exposed portion of the Central Cordillera of Guatemala. The males are

more slender than the specimens of the other sex, and they have the base of the elytra

more deeply emarginate, so that the shoulders project rather more in front. Except

in these sexual distinctions the series exhibits very little variation.

10. Epagrius simplex, sp. n.

Niger, subopacus, nudus; prothorace punctulato, dorso deplanato, lateribus utrinque subimpressis ; elytris

seriatim sat fortiter punctatis.

Long. 10 millim.

Hab. GuateMata, Quezaltenango 7800 feet (Champion).

Rostrum moderately finely and closely punctate, feebly impressed on the middle of

the anterior part, with a fovea between the eyes, the latter a little prominent. Thorax

elongate, rounded at the sides, the disc somewhat deplanate, and with two vague

irregular, oblique depressions one in front of the other; the surface is rather closely

punctulate and at the sides is rugose; the flanks are deplanate. Elytra with regular

series of moderately large remote punctures, the interstices not at all elevated, finely

punctate. One specimen.

This species differs from E. constans in the sculpture, and in the absence of the

large punctures on the disc of the thorax. From E. opacus and its allies it differs in

the details of sculpture, and in the fact that the disc of the thorax is only imperfectly

flattened and impressed.

EPAGRIUS. 135

i. Epagrius opacus, sp. n.

Niger, opacus, nudus ; prothorace densissime subtiliter punctato-ruguloso, dorso late leviter depresso, utrinque

Long. 12 millim.

Hab. Mexico, Chiapas (Sallé); Guaremana, Totonicapam 8500 to 10,500 feet

(Champion), Tepan (Conradt). .

Rostrum densely punctulate, feebly impressed along the middle, with a small fovea

on the forehead. Thorax elongate, densely covered with fine rugosities, but without

any definite punctures; the middle is occupied by a large deplanate space limited on

each side by a rather narrow elevation, outside which there is another longitudinal

depression of the surface. Elytra with the surface coriaceous, and with series of not

very large punctures placed at a considerable distance from one another.

We have received four specimens of E. opacus—all males. They have the base

of the elytra remarkably deeply emarginate and the shoulders considerably prolonged

in front. A specimen from Tepan is possibly a female of this species; it is very much

larger and broader, has the shoulders not produced, and the elytra smoother.

This is one of two species that were labelled Synthlibonotus viator, Chevr., in Sallé’s

collection.

12. Epagrius jugicola, sp. n. (Tab. V. fig. 23.)

Niger, opacus, nudus ; prothorace densissime punctato-ruguloso, dorso late depresso, utrinque longitudinaliter

impresso ; elytris peropacis, coriaceis, seriatim fortiter punctatis.

Long. 134 millim.

Hab. GuaTEMALA, Volcan de Agua 8500 to 10,500 feet (Champion).

I separate from EH. opacus two specimens of the male sex that have the sculpture of

the upper surface coarser, and the rostrum rather longer and more distinctly impressed

along the middle. The peculiar fine rugulose sculpture of the elytra is very remark-

able in this species, and the serial punctures are considerably larger than they are in

E. opacus. ‘The shoulders of the elytra are remarkably prolonged.

13. Epagrius foveicollis, sp. n. (Tab. V. fig. 24, 2 .)

Elongatus, sat nitidus, sublevis; prothorace dorso longitudinaliter impresso, in impressione bifoveolato ;

elytris seriatim subtiliter remote punctatis.

Long. 14-16 millim.

Hab. Mexico, Tepansacualco (Sa//é).

Rostrum short and broad, rather densely punctate, a little impressed in front and

canaliculate in the impression; a small, distinct fovea on the forehead. ‘Thorax

elongate, a little narrowed in front; an elongate, vague impression on the middle, in

which are placed two fovee or very large punctures, one in front of the other; each

side bears a short, irregular impression ; the surface generally is rather dull, and when

examined under a strong lens appears very minutely coriaceous and sparingly and

very finely, obsoletely punctulate. Elytra elongate, gently curvate at the sides, in-

tensely black, somewhat shining, very minutely punctulate, and also with regular series

of fine, remote punctures.

This very distinct species is remarkable on account of the great depth of the orbital

impression round the front of the eye, and the extremely deep depression at the base

of the under surface of the rostrum. Four examples have been received of it; the

male is smaller and more slender than the female, and has the elytra more parallel

and the shoulders slightly prolonged. ‘The insect was labelled “ Epicerus foveicollis,

Deyr.,” in Sallé’s collection.

14. Epagrius smithi, sp. n. (Tab. V. fig. 25.)

Gracilis, nigerrimus, politus ; prothorace medio depresso, utrinque subimpresso ; elytris sublevigatis, posterius

tenuiter setosellis.

Long. 11-13 millim.

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

Antenne slender, black, the club clothed with cinereous pubescence. Rostrum

shining, sparingly punctate, a little impressed along the middle, finely canaliculate,

with a fovea on the forehead. Thorax elongate, slightly narrowed in front; closely and

minutely punctulate, shining; an elongate depression on the disc, and another on each

flank. Elytra polished and shining, with the merest traces of the usual serial punc-

tures, the apical half feebly setose, and bearing a dark, thin squamosity that renders

the surface dull without much affecting its colour. .

About twenty examples of this very distinct species were procured by Mr. Smith.

The males are more slender than the females, and have the front angles of the elytra a

little more prominent, the suture of the elytra behind being less prominent.

sion, and each side broadly but slightly longitudinally impressed. Elytra with regular

series of somewhat large and distant punctures.

Chevrolat’s description! is so full of clerical and grammatical errors as to be

unintelligible; but it may possibly refer to this insect. The Guatemalan specimens

of the species in Sallé’s collection are labelled with the name I adopt, as is also an

example from Chevrolat’s collection communicated by Dr. Aurivillius. Sallé’s pair

from Chiapas, on the other hand, are ticketed §. viator, Chevr., and an example in

my own collection is named “ Graphorhinus planidorsis, Jekel.” The species is appa-

rently rare, and we have received but one or two examples from each locality. I

treat them all at present as belonging to one species; but if this be the case it must

be a very variable one. There is, however, no difficulty in identifying it, as none of

the forms come very near to any other species.

The description of Synthlibonotus viator, Chevr., is also unintelligible; but a speci-

men communicated by Dr. Aurivillius from Chevrolat’s collection is, I believe, a variety

of the male of his S. albosquamosus.

16. Epagrius preteritus, sp. n. (Tab. VI. fig. 1.)

Latus, niger, subnitidus, fere nudus; prothorace subtransverso, irregulariter haud fortiter punctato; elytris

seriatim obsolete foveolatis, interstitio tertio subelevato.

Long. 12 millim.

Hab. Mexico, Chiapas (Sailé).

Rostrum short, unimpressed in front, shining black, rather finely punctate, the eyes

not convex. Thorax 23 millim. long, 34 millim. broad, slightly narrowed in front; at

the sides somewhat coarsely and irregularly, on the disc more finely, punctate. Elytra

with each shoulder and base a little rounded, the scutellum quite distinct ; the sculpture

is obsolete, as if worn down, and consists of rows of subobliterated, remote, moderately

large punctures ; the third interstice is obscurely elevated for the greater part of its

length. First ventral suture greatly obliterated, the second, third, and fourth sutures

extremely deep. One specimen.

This is a most peculiar species that may possibly prove to belong to the ‘ Otiorhyn-

chine alate ;’ it has the scutellum and base of the elytra formed as in some members

of that division, the mesosternum short, and the side-pieces divided so that the suture

extends to the front. If #. preteritus proves to be provided with wings it will

probably require a new genus for its reception; the insect has, however, more the

appearance of EL. albosguamosus than of any other form, and I place it provisionally

near that species, though, as the two come from the same locality, it is possible the

resemblance between them may be of the kind called mimetic.

Long. 67 millim.

Hab. Guatemata, Totonicapam 8500 to 10,500 feet (Champion).

This species agrees closely in its structural characters with L. pumilus, and, like it,

has a large smooth surface on the anterior aspect of the rostrum. L. dwvinasus has,

however, the anterior face of the rostrum broader, and a distinct longitudinal channel

between the eyes, which are convex. ‘The squamosity of the elytra is dark, and the

pale marks are therefore more conspicuous; the interstices are very broad and not in

the least convex. ‘The scrobes of the rostrum are breader than in £. pumilus, and the

cavernosity of the hind corbels even more obscure. ‘Two specimens.

Hab. Guatemaua, Duefias (Champion), Tepan (Conradt).

Antenne slender; second joint of funiculus distinctly longer than the first; club

dusky red, rather elongate. Rostrum rather broader towards the front, the anterior

part free from scales, the vertex and the forehead squamose, the eyes scarcely convex.

Thorax not quite so long as broad, a little rounded at the sides and a good deal

narrowed in front, coarsely punctate, but the punctures concealed by the squamosity ;

this is slightly variegate, being mostly of a sordid grey colour, while down the middle,

and again on each side, there are some white scales. Hlytra a little rounded at the

sides, the base quite truncate, furnished with regular series of fine, definite punctures,

the interstices just perceptibly convex, squamose, and with numerous, rather short,

upright sete ; the squamosity is of a sordid grey colour, and there are some obscure,

apparently variable white marks. The legs are slender, the middle coxe only minutely

separated. Six specimens. ‘The female is rather broader than the male.

In this species the corbels of the hind tibie appear to be open; but on careful

examination it can be seen that there are two series of cilia at the apex, separated by a

very minute space.

Rostrum broader towards the apex, broadly depressed along the middle; eyes placed

near the thorax, very convex ; antenne with the scape setose and squamose. ‘Thorax

rounded at the sides, the surface rendered uneven by large vague depressions, and with

two large impressions placed along the middle, one in front of the other and more or

less confluent. Elytra truncate at the base, with the humeral angles a little prominent

and directed very slightly outwards, uneven, with coarse, closely-placed depressions ;

covered with a sordid squamosity of minute densely-placed scales, with an angulate

whitish band across the middle, and with a more indistinct similar band before the

middle, and another behind it. Legs squamose; posterior tibiz without mucro at the

hind angle.

We have received twenty-four examples of this very distinct species, several of them

being more or less abraded and dirty. Although it looks as if it should be placed in a

distinct genus, I can find no good characters to separate it; the front of the pro-

sternum is somewhat incrassate and dependent, so as to form a sort of lip, but this

character appears also, though to a less extent, in some other species,

Elytra elongate, marked with series of fovee or very large punctures, which are smaller on

the apical parts, the transverse interstices as distinct as the longitudinal ones ; the fovea

are partially filled with small scales, and there is a minute, scanty setosity on the inter-

Rostrum parallel, deeply canaliculate along the middle, the channel extending to the

transverse depression at the back of the head; lateral impressions deep, slender; eyes

quite prominent. Thorax very coarsely rugose, canaliculate along the middle; the sides

nearly straight from the base to near the front, then very abruptly narrowed. Elytra

very broad, convex, nearly twice as broad as the thorax; sculptured with very large

vague depressions, the interstices between these very irregular and indistinct, the third

more raised than the others for the greater part of its length, the fifth and seventh

also somewhat raised; the surface studded with minute granules, and also with very

small, squalid scales. Hind tibie furnished at the apex with a slender mucro, con-

cealed by a tuft of hairs.

is in any Epicerus.

slender and parallel.

This genus is proposed for three species, which it is better to separate from Epicerus

BRADYRHYNCHUS. 141

on account of the above characters. Very few Otiorhynchide have so short and broad

a rostrum. ‘The eyes are surrounded by a slender depression, and close to them on

each side there is a short depression to represent the lateral groove of Epicerus, but

no median groove. The absence of any incrassation of the hind tibia external to the

cilia would cause the insect to be placed in Lacordaire’s series with open corbels ; the

insertion of the tarsi, according to Horn’s phraseology, is intermediate between terminal

and lateral. The scrobes are deep, arcuate, and moderately broad and definite, and

the pterygia—although the rostrum is so broad—can be seen from the front.

Bradyrhynchus is the nearest approximation in our fauna to the N. American

Graphorhinus as defined by Horn and Leconte.

Hab. Mexico, Salazar (f/6ge).

Club of antenn acuminate-oval, not elongate. Rostrum extremely short and broad,

its anterior face a little uneven, but without groove; the forehead bears a well-marked

fovea, and there is a short lateral depression on each side close to the front of the eye.

Thorax strongly transverse, rounded at the sides and narrowed in front, black, with a

few pale, squalid scales; along the middle with some large punctures, those towards

the base being united to form an abbreviated channel. Elytra with regular series of

rather large punctures. Tarsi small.

We have received eight specimens of this species; they are all alike, and I do not

think the black squalid condition of the surface is due to abrasion.

fovea distinct. Thorax transverse, covered with fuscous squamosity, with a vague paler

vitta on each side, some large punctures scattered on the upper surface. Elytra with

regular series of rather fine punctures, covered with fuscous squamosity, with some

Head and rostrum separated by a broad vague depression ; front of the latter without

distinct impressions, even the lateral depressions vague ; club of antenna elongate oval,

acute. Thorax rugose-punctate, but the sculpture concealed by much squamosity.

Elytra with series of not very large, distant punctures.

We have received only one badly-preserved specimen of this species. Although

closely allied to B. hrevirostris, it may be easily distinguished by the transverse depres-

sion across the front of the head.

SCIORHINUS, gen. nov.

Rostrum latum, brevissimum, pterygiis superne omnino occultis. Oculi perconvexi.

Rostrum as broad as long, separated from the head by a broad depression between

the eyes; the front of the rostrum has a greater extension laterally than the pterygia,

so that these are not at all visible from the front; eyes extremely convex; scrobes

deep, lateral, strongly arcuate, so that their rather slender terminal part is directed

downwards ; scape short, smooth, and slender, except at the apex, which is much swollen.

Mentum rather large, filling the buccal cavity and quite concealing the palpi. Mandibles

very stout, the scars thick and prominent. Prosternum very much shorter than the

pronotum. Metasternum extremely short. Corbels of hind tibie rather small, furnished

with two very distinct series of apical cilie, separated by a slender glabrous space.

Second ventral segment quite short.

The broad flat face of the rostrum, quite concealing the pterygia from the front,

separates the single species for which this genus is formed from Epicwrus and Brady-

rhynchus. ‘The insect has somewhat the facies of the genus Strophosomus of the

Scutellum ad apicem processu transverso instructum. Femora anteriora subtus denticulata.

The insects forming this genus have the facies of the elongate species of Epicerus, but

they are well distinguished by the two characters given above. ‘The very peculiar form

of the scutellum is, so far as I know, unique in the Coleoptera: its use is very evident,

for although the wings are completely rudimentary, the elytra in Cle¢stolophus are not

soldered, but locked together by the transverse process that is placed on the top of the

scutellum ; this process can always be seen just behind the base of the elytra, where it

forms a sort of peninsula, the extreme base of the wing-case extending in front of it on

each side, but not quite meeting the similar projection from the other wing-case. ‘The

posterior femora are unarmed, but the anterior pair bear a distinct tooth, and the

intermediate pair a tubercle beneath. The other characters are the same as in the

typical forms of the genus Lpicerus.

1. Cleistolophus subfasciatus, sp. n.

Oblongo-ovalis, parum elongatus, squamosus, colore variabilis, vel viridescens vel grisescens; rostro brevi,

apice subattenuato, anterius fere inimpresso ; prothorace transverso.

Long. 7 millim.

Hab. Muxico, Playa Vicente, San Andres Tuxtla (Sal/é) ; Guaremaua (coll. Sharp) ;

Honpuras (Dyson) ; Nicaragua, Chontales (Belt).

Rostrum distinctly narrowed at the tip, its anterior face rather convex and scarcely

at all impressed on the middle; a fine channel between the eyes, which are rather

small and but little convex. ‘Thorax broader than long, the sides nearly straight behind

the middle, much narrowed in front, the surface densely squamose, with scanty, indi-

stinct, not coarse punctuation. FElytra not elongate, truncate at the base, with a very

slight constriction immediately behind the basal margin, densely squamose and bearing

series of fine punctures.

144 . RHYNCHOPHORA.

This species, although very variable, may always be distinguished from C. instabilis

and C. similis by the form of the thorax. Most of the examples I have seen are

labelled “ Epicwrus subfasciatus, Chevr.” In some individuals there are indications of

two vague dark fasciz across the elytra; but in the majority of specimens these are not

evident. I have seen but few examples, all differing more or less from one another.

I cannot identify the sexes with certainty.

2. Cleistolophus similis.

Epicerus similis, Chevy. Bull. Soc. Ent. Fr. 1880, p. 1xi’.

Elongatus, niger, griseo-squamosus ; prothorace subconico, squamoso, obsolete punctato.

Long. 83-15 millim.

Hab. Mexico, Tapachula in Chiapas (Hége); Brivise Honpuras (Blancaneaua) :

GuateMaLa (Salvin, Sallé), Zapote (Champion) ; Costa Rica! (van Patten), Caché

(Rogers).

This isa very variable species. It is closely allied to C. instabilis, but is more

densely covered with scales, and the punctuation of the thorax is quite indistinct ;

usually the punctures of the elytra are fine, but when the example is deprived of

scales these punctures appear considerably larger, though not so large as they are in

C. instabilis ; the scales are lighter in tint than those of C. instadilis, and some of them

—especially about the legs and the underside of the head—have a feeble metallic tint.

The rostrum is only feebly impressed on the middle, and towards the tip is glabrous

and shining; there is a minute fovea between the eyes. ‘he thorax is not so long as

broad and is narrowed towards the front; it is squamose, and very indistinctly punc-

tured. The elytra are squamose and bear series of fine punctures.

I have before me a series of about forty examples that I assign to C. similis; they

vary greatly in size, and a good deal in other points, such as the colour of the

squamosity and the size of the punctures on the thorax and elytra, but I can find no

means of distinguishing more than one species. The smaller examples very much

resemble some of the varieties of C. subfasciatus, while, on the other hand, some of the

larger specimens come very near to C. instabilis.

A specimen of Epicerus similis, from Costa Rica, communicated from Chevrolat’s

collection by Dr. Aurivillius, agrees exactly with examples our editors have received

from Costa Rica. An example in my own collection was ticketed Hpicwrus mopsurus,

Jekel.

3. Cleistolophus instabilis, sp.n. (Tab. VI. fig. 9.)

Elongatus, niger, plus minusve fusco-squamosus ; prothorace subcylindrico vel subconico, fortiter punctato,

antice leviter angustato ; rostro in medio late impresso.

Long. 9-14 millim.

Hab. Guatemaua, Senahu, San Juan, Chiacam, San Géronimo, all in Vera Paz

(Champion), Coban (Conradt).

CLEISTOLOPHUS.—BUFOMICRUS. 145

Scape of antenne slender; second joint of funiculus elongate, longer than the first

joint. Rostrum parallel, a little carinate on each side in front, and depressed between

the carin, a small fovea between the eyes. Thorax nearly or quite as long as broad,

very coarsely and irregularly punctate. Elytra elongate and slender, with very large

punctures occupying the greater part of the surface, these becoming finer behind; the

squamosity rather scanty, except on the apical part. Legs stout, the femora with but

few scales.

We have a series of eighteen examples to represent this species; it appears to be

distinct from C. similis, though both are variable. The male is more linear in form

than the female, and in this latter sex there is a slight longitudinal incrassation along

the middle of the apical portion of the last ventral plate.

BUFOMICRUS, gen. nov.

Corpus breve, squamosum. Antenne scapo modice elongato, oculorum marginem posteriorem attingente.

Scrobes profunde, angustz, laterales. Femora, vel omnia vel anteriora, dentata. Metasternum brevis-

simum.

The insects forming this new genus are remarkable on account of their broad, sub-

circular elytra. The mentum is large and completely conceals all the palpi. The

rostrum is short, not any broader at the tip; the scrobes are deep, curvate, entirely

lateral, sharply defined; the eyes are convex. ‘The anterior cox are placed very near

the front of the prosternum, which is not incrassate. The middle legs are but slightly

separated and the metasternum is remarkably short. The corbels of the hind tibiz

are feebly cavernous. ‘The claws are free.

These characters bring the genus very near to Lpicerus, but the dentate femora, in

conjunction with the peculiar shape of the body, are sufficient to distinguish it. One

of the three species I place in it—JB. cristatus—may have to be separated.

1. Bufomicrus squamosus, sp.n. (Tab. VI. fig. 10.)

Dense griseo fuscoque squamosus, breviter setosus, elytris transversim subvariegatis; prothorace minus

elongato ; femora omnia dentata.

Long. 53 millim.

Hab. British Honpuras (Blancaneaux); Guaremata, Teleman, La Tinta, Chacoj,

Tamahu, San Juan, Panima, all in Vera Paz (Champion).

Scape of antenne clothed with scales and hairs; second joint of the funiculus slightly

longer than the first. Rostrum and head densely clothed with scales, nearly flat, the

former very slightly concave in front, the latter with a minute fovea between the eyes ;

the eyes slightly convex. Thorax not so long as broad, much rounded at the sides, very

closely covered with scales that conceal the sculpture. Elytra very short and broad, at

the base only as broad as the thorax, then becoming rapidly broader, densely covered

with scales, and bearing numerous short, semi-erect sete; the scales are usually

variegate, forming two or three vague, slightly darker, transverse fascize, but sometimes

they are nearly or quite unicolorous; there are regular series of deep punctures—these,

when the scales are intact, appear rather small, but when the scales are removed they

are seen to be large and each to be separated from the one behind it by only a slender,

transverse interstice. Legs squamose, the teeth on all the femora acute.

A good series was obtained of this species, all from the Atlantic slope, those from

Guatemala coming from the Polochic valley.

2. Bufomicrus globipennis, sp. n.

Dense griseo-squamosus, subviridescens ; prothorace elongato ; femora omnia dentata.

Long. 6 millim.

Hab. GuateMaua, Yzabal (Saillé).

This species is closely allied to B. sguamosus, but can be recognized by the more

elongate thorax, the more convex eyes, and by the sete on the elytra being depressed

and differing very little from the scales, so that at first sight they escape detection ; the

rostrum is flat in front, without depression or fovea.

I have seen only two examples of B. globipennis; they differ a little from one

another in colour, and this character is probably of but little importance.

8. Bufomicrus cristatus, sp.n. (Tab. VI. fig. 11.)

Dense fusco-squamosus, parce hispidus, elytris cristis brevibus ornatis; femora intermedia et posteriora

mutica.

Long. 6 millim.

Hab. Guatemata, Sinanja (Champion).

Scape of antenne sinuous, slender and glabrous at the base, much thicker and

clothed at the apex. Eyes rather convex, a fovea between them. Thorax elongate,

rounded at the sides and narrowed in front, the surface apparently coarsely sculptured,

but completely covered with squamosity. Elytra covered with dark squamosity, which

is very obscurely variegate, bearing erect clavate sete, and with several short, slight,

cristiform elevations. ‘Tibi rather slender, hispid. The front femora with a large

angular dilatation beneath.

Only one specimen was procured of this remarkable species; it differs from its

congeners not only in the unarmed posterior femora, but also in the fact that the nasal

plate is surrounded by a curvate, glabrous, explanate space or margin; the scrobes, too,

are broader.

MASEORHYNCHUS, gen. nov.

Femora anteriora tuberculata. Oculi convexi, prope prothoracis marginem anteriorem siti.

The insect 1 separate under this generic name differs from Bufomicrus in numerous

minor characters, in addition to the two mentioned above. The elytra are not so

abbreviate; the rostrum is rather longer and not at all attenuate in front; the meta-

sternum, though quite small, is not so short; and the posterior tibie have a large

truncature outside the corbels, the truncature being densely setose. ‘The scrobes are

quite lateral and remarkably definite, extending quite to the underside of the anterior

part of the eye, which they touch for some distance. The impressions on the under

surface of the rostrum are remarkably deep. There is a feeble constriction of the

vertex immediately behind the eyes.

1. Maseorhynchus hondurensis, sp. n. (Tab. VI. fig. 12, 2.)

Convexus, griseo-squamosus et setosus ; prothorace convexo, squali, anterius rotundato-angustato.

Long. 6-9 millim.

Hab. British Honpuras, Belize, R. Sarstoon, R. Hondo (Blancaneauz).

Var. Squamulis pallide subviridescentibus.

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

Rostrum parallel, its anterior surface nearly flat, being scarcely at all impressed

along the middle; eyes very prominent ; first and second joints of funiculus elongate,

the latter very slightly the longer. Thorax large, curvate at the sides and greatly

narrowed in front, sparsely punctate, the sculpture quite concealed by the squamosity.

Elytra truncate at the base, with a very obscure elevation forming a sort of basal

margin; covered with densely crowded scales which are loosely fixed to the surface

and very easily removed, also with numerous short, coarse, pallid, subdepressed sete ;

bearing regular series of large punctures that are much obscured by the scales. Six

specimens.

The male of this species is apparently considerably smaller and more slender than

the female. Only one example of the elegant variety from Guatemala was obtained ;

it may possibly prove to belong to another species, as the scales on the elytra are larger

in size and not so crowded together, as well as different in colour.

MESTORUS.

Mestorus, Schiénherr, Gen. Cure. v. p. 910 (1889).

This genus was established for a single species from Mexico ; to this, two others

from the same country are now added. All appear to be very rare insects.

1. Mestorus adumbratus.

2. Mestorus crinitus, sp.n. (Tab. VI. fig. 13.)

Dense griseo-squamosus, setis erectis adspersus ; oculis convexis; prothorace elongato, subcylindrico, parce

punctato ; elytris convexis, regulariter seriatim punctatis.

Long. 6-8 millim.

Hab. Mexico (Sallé, ex coll. Sturm), Dos Arroyos in Guerrero (H. H. Smith).

Antenne with the scape squamose; second joint of the funiculus slightly longer than

the first. Rostrum very densely squamose, with erect sete or scales near the inner

margin of each eye. Thorax quite as long as broad, very slightly dilated at the sides

in the middle, and scarcely narrowed in front, bearing distant punctures which are

almost concealed by the dense squamosity. Elytra densely squamose, and bearing erect

white sete; convex and much rounded at the sides, greatly broader than the thorax,

with very regular series of fine but deep punctures. Legs squamose and setose. Front

femora angulate beneath.

This species may be readily distinguished from WZ. adumbratus by the elongate thorax,

by the eyes placed nearer to the front margin of the latter, and by the more distinctly

dentate front femora. I have seen only two examples, one of which is a very well-

preserved specimen from Sturm’s collection, in which it was labelled “ Lagostomus

crinitus, mihi.” Our figure represents this individual. The scales are very little

varlegate in this species.

3. Mestorus gracilis, sp. n.

Angustus, dense albido-squamosus, setis erectis adspersus; oculis fortiter convexis; prothorace elongato,

cylindrico ; antennis pedibusque rufo-obscuris, albido-squamosis. |

Long. 44 millim.

Hab. Mexico, Matamoros Izucar (/H6ge).

Rostrum broad and short, flat in front, canaliculate along the middle; eyes rather

small but very prominent ; antenne short. Thorax quite as long as broad, straight at

the sides and very slightly narrowed in front, coarsely sculptured, but covered with

nearly white squamosity. Scutelluny concealed. Elytra covered with white squamosity

that nearly conceals the sculpture; rather slender ; the erect sete quite white, rather

long, and almost transparent. Legs thick. One specimen.

The slender form and invisible scutellum distinguish this species from UV. crinitus;

besides this, it has no trace of armature on the front femora.

EUMESTORUS, gen. nov.

Rostrum breve, crassum ; scrobes laterales profunde, sub capite subtus duct ; caput post oculos constrictum ;

femora anteriora tuberculata.

The insects of this genus may be readily distinguished by the head being constricted

immediately behind the convex eyes, and by the scrobes being more prolonged beneath

the head than they are in the allied genera. The rostrum is quadrate, separated from

the head on the under surface by a deep depression ; the mandibular processes are very

prominent, the palpi completely concealed. The prosternum is emarginate beneath,

so that the anterior cox are placed close to the front. The metasternum is very

short, The second ventral segment is as long as the following two segments together.

The corbels of the posterior tibia are cavernous in a marked degree, there being a

conspicuous apical truncature between the two rows of ciliz external to the insertion

of the tarsus.

1. Eumestorus luctuosus. (Tab. VI. fig. 14, 9.)

Epicerus luctuosus, Chevr. Bull. Soc. Ent. Fr. 1880, p. lxii*.

Gracilis, niger, cretaceo-pictus ; capite inter oculos canaliculato-foveolato.

Long. 7-8 millim.

Hab. Mexico, Yucatan (Pilate!), Temax in North Yucatan (Gaumer).

Antenne rather short; first and second joints of the funiculus equal in length, not

elongate; club slender, acute. Rostrum very short, deeply triangularly emarginate in

front ; the eyes are convex, rather large, and encroach in front somewhat on the front

of the rostrum, between them is an elongate depression. ‘The thorax is elongate,

slightly narrowed in front and a little curvate at the sides; it is rather coarsely and

sparingly punctate, with a pale vitta along the middle, and a more obscure one on each

flank. The elytra are rather broader than the thorax, and are coarsely and somewhat

irregularly marked by series of distant impressions; they are covered in larger part by

pale squamosity having a very chalky appearance, and leaving some large marks, the

most conspicuous of which are an angulate band across the middle and an oblong or

oval mark at the base at each side; the whole of the upper surface bears scanty, very

minute depressed setze, the size of the sete being less than that of the scales.

A good series was obtained of this species, as well as of the next; the female is

usually larger and broader than the male, and has the suture of the elytra at the

declivity more prominent. We figure a specimen of this sex.

A type from his collection has enabled me to determine Chevrolat’s description as

belonging to this species.

2. Eumestorus proximus, sp. n.

Gracilis, breviter setosus, niger, griseo-squamosus, in elytris nigro-variegatus; capite inter oculos profunde

impresso.

Long. 6-7 millim.

Hab. Mexico, Temax in North Yucatan (Gaumer).

This insect is excessively similar to L. ductwosus, but differs in several respects, and

as a fair series was obtained there can be little doubt that the two are quite distinct.

E. proximus has the head more distinctly constricted behind the eyes; the setosity of

the upper surface erect and distinct, though quite short ; and the markings of the upper

150 RHYNCHOPHORA.

surface less abrupt and distinct. The rostrum is very short, and the margin of its

apical notch is strongly raised ; there is a depression between the eyes that becomes

broader but more indefinite anteriorly, and is abruptly limited a little in front of the

apical notch by a slight transverse elevation. ‘The mark at the shoulder of the elytra

is rather small, and in specimens that are not abraded is seen to consist of two smaller

dark marks separated by the width of one of the interstices. The difference between

the sexes is the same as in LH. luctuosus. .

EPITOSUS, gen. nov.

Antenne scapo elongato, prothoracis marginem anteriorem superante; oculi convexi; scrobes laterales,

latissims, posterius evanescentes ; femora dentata.

Rostrum moderately long, slightly broader towards the tip. Scrobes entirely lateral,

sharply limited in front, but becoming rapidly extremely broad and vague. Mentum

large, entirely filling the buccal cavity. Metasternum quite short, its episterna as well

as the mesothoracic epimera invisible. Apices of the posterior tibie a little enlarged,

feebly cavernous. |

This genus may be readily recognized: the very broad vague scrobes and the elongate

scape suggest that it may be considered to have some affinity, or propinquity, with the

Otiorhynchides proper; but as the position of the scrobes is entirely lateral and the

direction of their lower border is inferior, I place the genus near Hpicerus without

hesitation. The metasternal side-piece is quite concealed, the elytron extending to its

inner suture: in one or two specimens I think I see the mesothoracic epimeron as a

small piece of equilateral-triangular form.

1. Epitosus boops, sp. n. (Tab. VI. fig. 15.)

Angustulus, rugosus, squamulis griseo-viridescentibus minus dense vestitus, breviter hispidus ; rostro canali-

culato.

Long. 6-7 millim.

Hab. Guatemata, San Geronimo (Champion).

Antenne elongate; scape slender, passing on to the front margin of the thorax; first

and second joints of the funiculus elongate, the second slightly longer than the first.

Rostrum rather long, canaliculate along the middle; eyes convex. Thorax elongate,

rounded at the sides, much narrowed in front; the surface uneven, being coarsely but

irregularly punctured and feebly longitudinally impressed along the middle, bearing

griseous and grey scales and short depressed sete. Elytra rather elongate, truncate-

emarginate at the base, and slightly constricted immediately behind it; marked with

regular series of punctures and clothed with greenish and fuscous scales, distributed

in a somewhat irregular manner, but not forming a pattern, also bearing short,

suberect, pallid sete. Legs rather slender, squamose and setose.

A small series was obtained of this species; but I do not observe any sexual

distinctions, except that some examples are a little broader than others, and may

be females. .

PSEUDELISSA.

Pseudelissa, Casey, Ann. New York Acad. iv. p. 273 (1888).

Casey has recently established the two genera Hlissa and Pseudelissa for some small

Curculionide from the Southern United States, and has distinguished them, inter alia,

by the former possessing prothoracic vibrisse, while in the latter the prothorax is

said to be “ almost completely devoid of vibrisse.” I now refer to the genus Pseudelissa

an insect in which the prothoracic vibrisse are present, though in a not very conspicuous

manner. ‘This I do because I find that the vibrissze are undoubtedly present in Pseud-

élissa cinerea, Casey's typical species, though, as he says, in a most rudimentary

manner—the front margin of the prothorax bearing all round it some sete placed

widely apart, and these just behind the eye being a little longer and slightly more

approximate. It should also be noticed that in P. cinerea the eyes are placed quite

close to the prothoracic margin.’ In the Mexican insect that I assign to Pseudelissa

the eyes are placed some distance in front of the prothorax, and one or two of the

sete of the prothoracic margin are elongated so as to form true vibrisse. Casey

gives as another character of Pseudelissa that the mentum is rather deeply seated ;

this character was no doubt observed correctly in the specimen examined, but it was

almost certainly due to a post-mortem contraction, as the mentum is quite superficial

in the specimens I have examined of P. caseyi and P. cinerea. Notwithstanding these

slight detractions from the validity of the characters given to differentiate Pseudelissa

from Elissa I think the two should be maintained as distinct, Hlissa possessing a well-

marked scutellum and a remarkably broad mentum, as well as a very peculiarly-shaped

prothorax.

Casey, making use of Lacordaire’s classification, correctly assigned EHilissa to the

“Tanymécides,” which group is supposed to receive all the Otiorhynchids that have

no trace of ocular lobes, but that do possess vibrisse. lissa and Pseudelissa are,

however, unnaturally placed amongst the “Tanymécides,” and I should limit that

group to forms that possess wings, while the two genera under discussion are certainly

apterous. I accordingly place them in the “Otiorhynchine aptere,” where they will

form a small group characterized by the scrobes being lateral in situation and angulate

in front, and by the anterior margin of the prothorax being provided with a peculiar,

membranous border, formed of agglomerated scales.

1. Pseudelissa caseyi, sp.n. (Tab. VI. fig. 16.)

152 RHYNCHOPHORA.

Antenne rufescent, the club fuscescent. Rostrum very short, entirely covered with

deep ruge; head very prominent between the eyes, these being small, quite circular,

convex, and placed at some distance in front of the thoracic margin. Thorax cylindric,

scarcely so long as broad, truncate in front and behind, very coarsely and deeply rugose.

Elytra considerably broader than the thorax, witn free but rounded shoulders there

is no visible sculpture, but the surface is densely covered with a squamosity irregularly

spotted with whitish and blackish colour, the alternate interstices just perceptibly

more elevated and furnished with short sete. Legs slender, rufescent, clothed with

whitish sete.

About a dozen examples have been received; the surface in old specimens becomes

very sordid, and the serial sete can then scarcely be detected. The insect is probably

subaquatic in its habits like its North-American congeners, Of the latter 1 have

received types from Capt. T. L. Casey, after whom I have much pleasure in naming

this interesting species.

In P. caseyi the metanotum is entirely membranous, and the elytra are completely

consolidated along the suture.

PANTOMORUS.

Pantomorus, Schonherr, Gen. Cure. v. p. 942 (1839) *.

Athetetes, Pascoe, Ann. & Mag. Nat. Hist. (5) xvii. p. 415 (1886),

This genus is closely allied to Naupactus, from which it differs in the species being

apterous. The brief characters given for the genus by Lacordaire are erroneous, the

insertion of the antenne being terminal as in the allied genera. Thus it is not

surprising that a fresh name should have been proposed for the genus by Pascoe, who

distinguished it correctly from Naupactus by the absence of shoulders. Schénherr

understood the genus so imperfectly that he placed most of the species known to him

in Naupactus.

Pantomorus appears to be specially characteristic of our region, a few species only

having as yet been found in 8. America, while none have been recognized as occurring

in the United States.

Two of the species described here—P. distans and P. robustus—are assigned only

with considerable doubt to the genus; and I think it probable that when specimens

can be obtained for examination they may prove to possess partially developed

wings.

Two natural groups of Pantomorus exist, viz.:—

1, Male without mucro on the middle tibia. (Species 1-23.)

2. Male with a mucro at the inner edge of the extremity of the middle tibia. (Species 24-82).

We have received a fair series of examples of this species from the above localities,

and from some other localities a few single specimens that may possibly belong to it or

to one or more distinct species; but these latter more probably are extreme varieties of

P. albosignatus, the variation affecting the colour and markings, and even to a slight

extent the elongation of the hind-body. One of these varieties is labelled Naupactus

Iam unable to identify any of the Mexican insects we have received with this

Long. 53-7 millim.

Hab. Mexico, Juquila, Etla, Las Peras (Sallé), Jalapa, Cerro de Plumas (H6ge).

This is similar to some of the varieties of small size of P. albostgnatus, but it has the

scrobes quite slender, sharply defined behind, and passing close to the eye. The

antenne are slender, with the third joint twice as long as thesecond. ‘The rostrum and

head are canaliculate, the eyes moderately prominent. The thorax is short, rounded at

the sides, covered with scales that conceal the sculpture, finely canaliculate along the

middle; the scales are pale grey in colour, but there are three vague darker fuscous

stripes, and there is also a very short setosity. ‘The elytra are rather narrow, the base

scarcely broader than the base of the thorax, the shoulders not rounded, the sides very

little curved, but becoming a little broader to behind the middle ; they bear long, erect

~ setae, and are covered with scales, which are, over the larger part of the surface, pale

erey or whitish, but in other parts—especially about the sutural region—are dark

brown. ‘The under surface is clothed with whitish scales. Six specimens.

The individuals of this species are smaller than any other Pantomorus or Naupactus

known to me. In Sallé’s collection it was labelled ‘ Naupactus perarduus, Chevr.”

scales. Elytra elongate, uniform in colour with the thorax, with some obscure lateral

paler markings; the punctures of the striz quite fine, the erect hairs fine and moderately

numerous. Legs red, or nearly black. Two specimens. |

The much more elongate elytra will prevent this insect from being mistaken for a

variety of P. albosignatus. In respect of the length of the antennz it is intermediate

between that species and P. contractus.

be distinguished therefrom by the longer and more slender antenne. It varies some-

what in the extent of the pallid marks, but not so as to obscure their disposition, except

in the case of the variety noticed above. I have seen only eight examples of the species,

two of which are from Sturm’s collection and are labelled—one WN. pulchellus, the

other WV. formosus, Sturm.

the second. Rostrum broad and short, very delicately canaliculate, closely and finely

sculptured, bearing numerous minute scales of various metallic tints. ‘Thorax mode-

rately short, very densely and finely sculptured; black, setose, with a very distinct band

of pale scales on the flank, another between this and the middle, and a much more

slender one along the centre. Elytra with numerous rather long, erect, black sete ;

black, with an elongate lateral mark of pallid scales, and between this and the suture with

another line of scales—this line commences at the base of the third interstice, but then

passes to the fourth interstice, and is interrupted just before the middle, reappearing

behind the middle as a small spot on the third interstice, and as a longer mark just

before the apex; there are also numerous scales about the sutural portion; the punc-

tures of the strie are rather large and are quite distinct, not being concealed by the

squamosity. Legs obscure red.

We have received seven specimens of this species; those in Sallé’s collection are

labelled Naupactus picipes, Chevr. The very dense fine sculpture of the thorax, the

third joint of the antenne not so long as in most of the other species, and the markings

are the characters that will lead to its recognition.

The three specimens with an uninterrupted line down the elytra that I have treated

as a variety may possibly prove to be distinct.

7. Pantomorus salvini, sp.n. (Tab. VI. fig. 17.)

Minor, gracilis, setis erectis minus brevibus vestitus, niger, pedibus rufis; elytris linea suturali aliaque laterali

Long. 53 millim. .

Hab. Gvuatemata, Aceytuno 5100 feet (Salvin).

Rostrum densely sculptured, almost without scales, deeply canaliculate, and with

an obscure lateral margin in front. Thorax rather coarsely rugose, with an indistinct

median line, and a still more obsolete lateral vitta. Elytra with series of large, very

distinct punctures; the sutural and lateral vitte of green scales very distinct and

regular.

Only two specimens of this species were obtained ; it is one of the easiest to recognize

of the genus.

g. Pantomorus mollis, sp. n.

Niger, minus dense griseo-viridi-squamosus, subvittatus, breviter hispidus; rostro profunde canaliculato,

Long. 64-7 millim.

Hab. Mexico, Chilpancingo in Guerrero (fHége).

Not very densely clothed with greyish scales tinged slightly with green; these are

more condensed in certain places, so as to give a slight appearance of longitudinal

bands. ‘The antenne are black, elongate, the second joint of the funiculus nearly

twice as long as the first. Head and rostrum setose and sparingly squamose, deeply

canaliculate along the middle, with a slight carination of the side over the insertion

of the antenne. Thorax with a short, very deep canalicular impression at the base in

the middle; the sculpture moderately coarse and not close, obscured by the clothing.

Elytra with fine, erect, short hairs, the greenish-grey squamosity not so distinct in

some places and thus giving rise to the appearance of two somewhat abbreviate and

indefinite black bands.

Fourteen examples have been obtained of this species; they do not vary much.

There is a well-marked difference between the sexes, the male having the rostrum

longer, more distinctly carinate on each side, and the antenne a little longer and

thicker than in the female.

9, Pantomorus facialis, sp. n.

Niger, irregulariter sculpturatus, griseo-squamosus, brevissime squamoso-hispidus ; rostro late et profunde

canaliculato, utrinque evidentius carinato.

Long. 7-8 millim.

Hab. Mexico, Putla (Salié).

Antenne moderately stout, very long, the second joint elongate, but only about half

as long as the third joint. Rostrum moderately long, not rugose, bearing a few scales ;

the channel very deep and broad in front, the edges distinctly subcarinate, so that the

lateral depression in front of the eye and the insertion of the antenna on each side is

unusually distinct. Thorax short and broad, canaliculate along the middle, the channel

deep at the base. Elytra with the punctures rather coarse. Three specimens.

I have not described the squamosity, as the examples are a good deal abraded; but

the scales evidently do not form any definite pattern, and probably are very easily

removed. P. facialis may be distinguished from P. mollis by the hispid clothing

being very short, and the head being broader and with broader channel, as wel! as by

the antenne being a little thicker and shorter.

10. Pantomorus asperatus, sp. n.

Fusco-squamosus, griseo-lineatus, dense breviterque fusco-hispidus ; antennis longioribus.

Long. 63 millim.

Hab. Mexico, Acapulco (Hége, H. H. Smith), Dos Arroyos in Guerrero (H. ZH.

Smith).

This insect is narrower in form than P. albosignatus, and has much longer antenne ;

it is remarkable on account of the character of the sete, which are shorter, stouter,

and more numerous than they are in most of the other hispid species. The antenne

are rather stout, very long, the last joint of the funiculus more than twice as long as

broad, the club very long. The rostrum is long, depressed along the middle, rather

deeply canaliculate, carinate on each side. Thorax stout, rather coarsely sculptured,

fuscous, with five vague pale vitte, the central one quite indistinct, the outside one

PANTOMORUS. 157

placed on the flank. Elytra fuscous, with a narrow elongate pallid stripe near the

suture, a lateral elongate mark, and between these with more or less indistinct smaller

marks; the short dense sete give them a rough appearance. Four specimens.

One of the examples of this species has a curious malformation of the antenne,

there being only five joints in place of seven in the funiculus of each, and the joint

preceding the club bearing a small tubercular prominence.

11. Pantomorus affinis, sp. n.

Niger, fere uniformiter griseo-squamosus, sutura lateribusque pallidioribus, hispidus ; rostro in medio canalicu-

lato, utrinque carinato.

Long. 63 millim.

Hab. Mexico, Oaxaca (Hoge).

I have before me only two specimens of this species, both apparently of the male

sex. Though very similar to the more uniformly coloured examples of P. crinitus, I

cannot associate them therewith, the rostrum being longer, distinctly carinate on each

side, and the antenne longer and stouter; as these characters are not likely to be so

conspicuous in the female, that sex will no doubt be very difficult to distinguish. The

antenne are remarkably long, moderately stout, the second joint of the funiculus quite

twice as long as the first. The rostrum is a little depressed along the middle, with the

lateral carinee strongly marked, the channel only moderately deep and fine. ‘The

thorax is almost uniformly covered with scales, not vittate. ‘The elytra bear very

distinct fine erect sete, and the punctures in the strie are large.

Hab. Mexico !, Orizaba, Toxpam, Vera Cruz, Playa Vicente (Sallé), Atoyac (H. H.

Smith), Cordova, Tapachula in Chiapas (L/6ge).

This I look upon as a very variable species, not being able to find any good

distinctive characters for separating some forty or fifty examples of it. It varies

greatly in colour, being nearly uniformly greenish-grey, or of the yellowish-grey colour

described by Boheman, with metallic sides, or pallid grey with brown spots. It includes

not only the examples labelled P. crinttus in collections, but also most of those that I

have seen named P. nobilis.

The antenne are quite slender, the rostrum finely canaliculate ; the scales are small

and neatly arranged; the sculpture is fine, and the surface bears fine, not very

numerous erect hairs.

Pantomerus nobilis, Chevr. Bull. Soc. Ent. Fr. 1879, p. cxxx.

Hab. Mexico, Alvarado (coll. Chevrolat 1).

The type of this species communicated to us by Dr. Aurivillius from Chevrolat’s

collection does not quite agree with any other example before me. It comes very

close indeed to some of the greenish-grey unicolorous examples of P. crinitus ; but the

head is more convex between the eyes, and the rostrum more deeply canaliculate, so

that it is possible the insect may prove to be distinct from P. crinitus.

14. Pantomorus sobrinus, sp.n. (Tab. VI. fig. 18.)

Niger, capite prothoraceque parce squamosis; elytris densius fusco-griseo-squamosis, haud variegatis, setis

erectis, brevibus, tenuibus vestitis ; tibiis piceis.

Long. 8-9 millim,

Hab. Guatemaa, Capetillo, Duenas (Champion).

Antenne rather long and slender; second joint of funiculus long and slender, more

than one and a half times as long as the first. Rostrum moderately long, canali-

culate. Thorax strongly transverse, much narrowed in front, sprinkled with minute

scales, the interspaces black and shining. Elytra with very regular series of rather

fine punctures, moderately densely covered with minute scales, which are tawny-

fuscous, greyish along the flanks, in colour, and bearing short, very fine, quite erect

hairs.

We have received ten examples of this species. It is allied to P. crinitus, though

the two are not very much alike when seen together; but, independently of the facies,

it may be distinguished by the fact that the mucro of the front tibia—which is present

in all the varieties of P. crinitws—can scarcely be detected in P. sobrinus. I do not

perceive any sexual distinctions. The depth of the colour is variable.

15. Pantomorus subcinctus, sp. n.

Niger, minus dense griseo-squamosus, elytris setis erectis regulariter vestitis; prothorace vitta sublaterali,

elytrisque signaturis post humeros densius pallide-squamosis.

Long. 73-8 millim.

Hab, GUATEMALA, near the city at an elevation of 5000 feet (Salvin), San Gerénimo

Antenne moderately long and slender ; second joint of funiculus only one and a half

times as long as the first. Rostrum quite short, very finely canaliculate. Thorax

strongly transverse, with very little sculpture, and only sparingly squamose, so that

the surface between the scales is quite distinct and is shining; there is no trace of

any channel ; on the flanks there is a line of dense squamosity of a pallid colour, but

frequently tinged with yellow by some efflorescence. Elytra rather elongate, the series

of punctures somewhat indistinct, the interstices more densely clothed with scales than

the thorax; at the anterior part of the sides with two separated marks of paler and

denser squamosity ; armed with fine, long, erect, scanty hairs; there is usually a slight

condensation of the scales along the suture.

A good series of this insect, which is known in collections as P. subcinctus, Jekel,

was obtained by Mr. Salvin, and one specimen by Mr. Champion. It comes somewhat

near to P. crinitus ; but the elytra are usually more elongate, and their clothing is

different from what it is in any of the varieties of P. crinitus.

16. Pantomorus faber, sp. n.

Niger, sat dense squamosus, antennarum scapo tibiisque rufis; elytris ovalibus, ad latera circaque suturam

Hab. Costa Rica, Volcan de Irazu 6000 to 7000 feet (Rogers).

Antenne rather long, moderately stout; second joint of funiculus less than one and

a half times as Jong as the first; the joint before the club nearly twice as long as broad.

Rostrum sparingly squamose, not elongate, the channel deep. ‘Thorax strongly trans-

verse, much rounded at the sides; black, with a line of dense pallid squamosity on the

flank and with a slight condensation of the scanty scales along a vague space on each

side of the middle ; obsoletely canaliculate. Elytra slender, curvate at the sides; with

an elongate lateral mark of pallid scales, twice nearly interrupted by the dark colour,

and also with pallid scales distributed broadly along the sutural region; the erect

hairs fine and rather long, but scanty. Legs red, with the femora more or less

obscure. ‘Two specimens.

The only species this much resembles is P. subcinctus; but besides differing from

that insect in colour and in its more oval elytra, it has the second joint of the funi-

culus rather shorter and thicker.

17. Pantomorus dorsalis, sp. n.

much rounded at the sides, scarcely at all narrowed in front; it and the head and

rostrum are of an intense black colour, rendered grisescent by depressed pallid sete ; on

the flank there is a longitudinal area clothed with pallid scales. The elytra bear

series of very coarse punctures, and at the sides are clothed with griseous scales, but

these leave a broad area along the suture black; the erect sete are very fine, rather

long and numerous.

A series of nearly twenty examples was obtained of this species; it exhibits but

little variation.

Long. 7-84 millim.

Hab. Mexico, Tapachula in Chiapas (Hége) ; Guatemata (Sallé), Zapote (Champion),

Tepan (Conradt); Costa Rica (Van Patten).

Antenne very long; second joint of funiculus twice as long as the first. Rostrum

rather long, deeply canaliculate. Thorax much rounded at the sides, but little

narrowed in front; black, but clothed with ochraceous-viridescent scales in such a

manner as to leave three more or less obsolete longitudinal black vitte. LElytra with

rather fine series of punctures, densely clothed with scales, the lateral parts of which

are greenish-yellow ; the suture is broadly black from the base to the apex, and the

scales next the black portion are usually more viridescent than those outside them ; the

erect setosity is short and is pallid in colour. The male is considerably more slender

than the female.

This insect may be readily distinguished from P. dorsalis by the colour, and by the

different setosity on the elytra; it has always some scales on the thorax, and the

antennz have the second joint of the funiculus considerably longer and more slender

than it is in P. dorsalis. Sixteen examples are before me.

Antenne very elongate. Rostrum rather long, deeply canaliculate, not squamose

and only sparingly setose. Thorax strongly transverse, much rounded at the sides,

free from squamosity except at the sides, black, a little shining, rather ‘closely but

subobsoletely sculptured. Elytra with series of large but not deep punctures, these

becoming obsolete behind ; near the sides with an elongate slender vitta of yellow or

yellowish-white scales or setee—continuous with a similar one at the sides of the thorax,

—this near the apex extending inwards but not quite meeting the one on the opposite

elytron; there are a few sete at the apex. The front legs are very long, black, with

the tibize picescent or black; the intermediate and hind tibie are distinctly red. Under

surface cluthed with pallid scales or setosity.

About a dozen specimens were procured of this distinct species.

Hab. Muxtco, Alvarado (coll. Chevrolat 1), Vera Cruz (Sallé, Hoge).

We have received a fair series of this species from Hodge. It varies a good deal in

colour, the variegation of the elytra being in some examples very slight: such indivi-

duals appear at first sight intermediate between P. stupidus and P. uniformis; but the

scales in P. stupidus are never brilliant, and the surface is destitute of the short rough

setosity that exists in P. wniformis.

21. Pantomorus uniformis, sp.n. (Tab. VI. fig. 21.)

Hab. Mexico, Vera Cruz (Hége).

Antenne slender, black, clothed with much pallid setosity ; third joint twice as long

as the second; club very slender. Rostrum deeply canaliculate. Thorax short and

broad, much narrowed in front. Striz of the elytra fine, obscured by the pubescence.

Rostral scrobes deep and definite, rather slender.

We have received a series of about forty examples of P. uniformis; it cannot be

confounded with any other Pantomorus on account of the dense uniform covering of

golden-green scales. The male is more slender than the female, and has the front of

the rostrum slightly depressed along the middle.

22. Pantomorus rufipes, sp. n.

Antenne moderately long; second joint of the funiculus hardly one and a half times

as long as the first. Rostrum rather short, canaliculate, subcarinate on each side.

Thorax short, very finely sculptured, canaliculate along the middle, the channel

obsolete in front, moderately deep behind, covered with minute green scales. LHlytra

long and narrow, not convex longitudinally, covered with minute green scales, and

bearing a minute, very short setosity ; the punctures fine. Legs red, elongate ; anterior

femora a little incrassate.

We have received only two examples of this distinct species. The scutellum is

more distinct than in any other member of the genus, but I have very little doubt as

to P. rufipes belonging to the apterous series.

We have ‘received about a dozen examples of this species. In some of them there

is an obscure squamosity that renders the surface somewhat grisescent; these are

probably quite fresh examples, and this slight clothing is no doubt very readily

rubbed off. The scrobes are broad, slightly broader than they are even in P. albo-

with tawny scales, with a broad channel along the middle in front. Elytra slightly

broader at the base than the thorax, the shoulders being a little oblique; densely

covered with scales similar to those on the thorax, with an indefinite denuded space

on the middle of the suture, near which there may be a few greenish scales; there

are some very fine, erect, pallid sete. Legs elongate; a well-marked mucro at the

apex of the front tibiz, and a smaller one on each of the middle tibia. Two speci-

This species resembles P. picturatus rather than any species of the group in which

I place it; although the mucro on the intermediate tibia is small, its existence is

Long. 94-10 millim.

Hab. Mexico (Sal/é).

Antenne slender, only moderately long ; first joint of funiculus elongate, the second

scarcely one and a half times so long as it, the last joint not one and a half times as

long as broad. Head and rostrum broad, finely canaliculate. Thorax much narrowed in

front, not canaliculate, coarsely punctate. Scutellum distinct. Elytra broad, narrowed

at the shoulders, scarcely striate, but with rows of more than usually distinct and

definite punctures. Three specimens.

In this species the scales are not crowded, each one being isolated, and they are nearly

evenly distributed over the surface; the elytra are obscurely variegate with pale grey

elongate spots. The male is much narrower and more parallel than the female, the

sex represented on our plate, and has three minute black tubercles placed in a trans-

verse row on the middle of the second abdominal segment. P. brevipes was mixed

with P. globicollis in Sallé’s collection, and the females of the two species almost

exactly resemble one another; but P. brevipes has differently formed antenne, a quite

distinct scutellum, and hispid surface.

Antenne very slender; second joint of the funiculus quite twice as long as the first.

Thorax elongate, in the male longer than in the female and more convex longi-

tudinally. Elytra with the suture distinctly prominent on the declivity ; furnished with

excessively short, minute, pallid, recumbent setosity, in addition to the dense clothing of

pallid scales ; this setosity more distinct on the elevated part of the suture. Male

with a transverse series of five or six tubercles on the second ventral plate.

Distinguished by the very pallid colour and the great sexual disparity; the males

and females looking at first sight as if they belonged to distinct species on account of the

ereat difference of outline. We have received ten examples of the species; it varies a

little in colour, a few of the scales being in some cases tinged with pallid ochreous-

brown so as to cause a slightly vittate appearance. Our figure is taken from the male

example procured at Venta de Zopilote.

in the female. Thorax elongate, rounded at the sides, a little narrowed in front, and

in the female slightly narrower than the elytra; in the male longer and more globose.

Hab. Nicaraeva, Chontales (Belt).

We have received only a single specimen of this species. It is a male, of slender

form, greatly resembling P. globicollis, but distinguished from it and all other species

of the genus by the slight convexity of the eyes. The rostrum is parallel-sided,

scarcely at all narrowed in front. The antenne are obscure red, with the club black,

_ the second joint of the funiculus not quite twice as long as the first. The thorax is

convex longitudinally, as well as rounded at the sides; it is covered with scales and

squamose setosity, the clothing being a little darker along the middle than at the

sides. The elytra are clothed with scales, mingled with much thick suberect setosity,

the colour being nearly white, with fuscous markings across the middle and base; the

punctures in the striz are very approximate. ‘There are two tubercles on the second

ventral plate; the front and middle tibie are each armed with a sharp mucro on the

inner part of the apex, but there is no mucro on the hind tibia.

31. Pantomorus femoratus, sp.n. (Tab. VII. fig. 2, 3.)

Of this species only one example has been obtained; it is a male and has all the

tibize furnished with an acute mucro at the apex internally. P. femoratus is as yet

the only species of Pantomorus known to have the hinder tibie of the male mucronate.

There are no tubercles on the second ventral plate; but the basal portions of the

middle and hind cox, the middle of the breast, and the first ventral segment are

strongly pubescent. ‘The front femora in this sex are more inflated than they are in

any other Pantomorus. The antenne are rather elongate, the second joint of the

funiculus not quite twice as long as the first. ‘The rostrum is much narrowed in front,

the channel on it short but somewhat deep ; the eyes are very convex. ‘The thorax is

rather short, and is remarkable on account of the great rounding of its sides in front ;

it is convex longitudinally, obscurely canaliculate along the middle, evenly covered

with uniformly coloured scales, mixed with very minute recumbent sete. LHlytra

slender, with the shoulders slightly prominent, bearing very regular series of punctures,

uniformly covered with pale fawn-coloured scales, and bearing very fine erect sete.

32. Pantomorus robustus, sp. n. (Tab. VII. fig. 3, 2.)

Latior, niger, pallide griseo-squamosus ; elytris breviter subtiliterque hispidis, prothorace evidenter latioribus.

Long. 13 millim.

Hab. Nicaragua, Chontales (Belt).

Antenne rather short. Head and rostrum broad, with a short channel on the

middle, the rostrum short, a little narrowed in front. Thorax broad and short, much

rounded at the sides, finely canaliculate along the middle, the basal portion depressed.

Scutellum small, subelevated. Elytra at the shoulders broader than the thorax, the

shoulders a little oblique, with series of fine punctures, uniformly squamose, and

bearing very fine short, erect, pale sete.

I have described this species from two examples of the female sex. Its position is

altogether doubtful; but as it has more resemblance to the female of P. albicans than

to any other insect known to me, I therefore place it here. It is, however, far from

improbable that when the condition of the wings can be examined, P. rodbustus may

prove to be a Naupactus, or, as is I think even more likely, the type of a genus

between Naupactus and Pantomorus.

PYCNOPHILUS, gen. nov.

Corpus setosum ; elytris prothorace latioribus. Scrobes late et profunde, curvate.

Rostrum broad and short, not emarginate at the tip, which is formed in front all

across of a shining substance more prominent than the upper part of the rostrum;

eyes rather large and convex. Scrobes quite lateral, broad, deep and definite, the

upper margin directed to the middle of the eye, the lower in front of and below it.

Scape attaining the posterior margin of the eye, setose. Mentum small, the maxille and

all the palpi exposed. Prosternum short; anterior coxe contiguous, placed near the

front margin and about twice as far from the hind margin. Metasternum rather short.

First two ventral plates elongate, the suture between them strongly angulate; the

third and fourth plates short. Legs slender; femora unarmed; tips of the hind tibie

slender, but terminated by two series of ciliz enclosing a small space; claws moderate

in size, free. The outer elytral stria distinct at the base only.

This genus, in my first arrangement of the Otiorhynchide of our Editors’ collection,

was excluded from the Epicerina on the supposition that it belonged either in the

neighbourhood of Sctaphilus or to the winged series. On examination it appears that

it can be placed in neither of these categories, but that it may come near to Panto-

morus. For this reason, Pycnophilus is not included in the Key to our genera of

Epicerina on p. 101. On the whole, it seems, as I have said, best placed near

Pantomorus, from which, however, it differs strongly in the scrobes, as well as in

general appearance.

PYCNOPHILUS. 167

1. Pycnophilus piceus, sp. n. (Tab. VII. fig. 4.)

Piceus, parce griseo-squamosus, setis tenuibus erectis vestitus, elytris seriatim fortiter punctatis.

Long. 57 millim.

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

Rostrum finely canaliculate on the middle, squamose and setose, with the tip

shining and elevated. Antenne red; second joint of funiculus as long as the first ;

club abrupt. Thorax transverse, strongly rounded at the sides, obscurely rugose,

squamose, and bearing erect sete. Hlytra broad at the base, but with the shoulders

quite rounded ; somewhat convex, sparingly squamose, and bearing numerous erect,

rather long, fine hairs, which, however, are not acuminate, and with distinct series of

large punctures. Legs slender, setose; tarsi red. Under surface clothed with only a

very few scales. One specimen.

Group SCIAPHILINA.

This group includes such of our apterous Otiorhynchide as have no ocular lobes,

but have the claws connate and the scrobes lateral, descending rapidly at some distance

in front of the eyes. All the genera have a small mentum, leaving the maxille

exposed, slender antennze, and posterior tibie with delicate tips, the corbels being

quite simple. There are numerous European forms very closely allied to those of

our region; but the only North-American genus in Horn’s work that I can indicate as

pretty certainly belonging to the group is Mitostylus, which he places in the Phyllo-

biini. The Phyllobiina should, however, be: restricted to winged forms, with vague,

superior scrobes.

It is, nevertheless, highly probable that there are other North-American genera

belonging to this group. I think it will be found to be the rule in the Otiorhynchide

that when the mesosternal epimera are intermediate in size the species belong to the

apterous series. Horn, however, appears to have referred most of the Otiorhynchidee

with an intermediate form of epimera to his second division, which consists principally

of winged forms.

If these apterous forms were transferred from Horn’s Division II. to his Division I.,

they would be probably found to agree partly with the Sciaphilina as here treated,

though some of them almost certainly belong to the Epicerina. The group ** Artipi ”

seems to belong to the Epicerina (indeed, I feel little doubt from the description that

some of the species of Aramigus and Phacepholis placed in it belong to the genus

Pantomorus) ; while the ‘“‘ Aphrasti”’ may possibly prove to belong to a group not repre-

sented in our region, but allied to the Cneorhini of the Old World. The group “ Omilei ”

probably belongs to the Epicerina, as suggested by Horn; and Mitostylus of Horn’s

group Phyllobiini I have already noticed as being probably near Sciaphilus.

If these comparatively slight changes were made, the arrangement of the North-

168 RHYNCHOPHORA.

American Otiorhynchide would, I think, nearly correspond with that I have used for

the forms found in our region.

DEROSOMUS, gen. nov.

Antenne scapo valde elongato, tenuissimo ; coxee posteriores late distantes; abdomen segmento secundo ven-

trali tertio longiore.

Form elongate and slender; with long, very slender antenne, whose scape extends

back on to the front of the prothorax. Rostrum not dilated at the tip; nasal plate

elongate, with slightly elevated margin. Lower border of the scrobe very definite,

the lateral border rapidly descending at a considerable distance in front of the eyes,

the upper border indefinite, but defined by the scales. Eyes oval, only moderately

prominent. Mentum very small, leaving the maxille exposed at its sides and all the

palpi visible. Scutellum small, acuminate. Metanotum short, semimembranous; wings

absent. Metasternum moderately long. Hind cox widely separated. Lateral edge of

the elytra very strongly sinuate, the tenth series of punctures quite indistinct. First

ventral suture nearly straight ; third and fourth ventral plates rather long.

The facies of the species of this genus is quite that of the European Eusomus ; but in

Derosomus, and indeed in all of the Sciaphilina of our region, the femora are unarmed.

Horn’s description of Mitostylus («N. Am. Rhynchophora,’ p. 107) seems to indicate

with certainty that it is an apterous form; but I doubt very much whether Derosomus,

or any of the genera I describe below, will prove to be congeneric with it.

1. Derosomus fragilis, sp.n. (Tab. VII. figg. 5, ¢; 5a, front tibia.)

Gracilis, piceo-niger, griseo-squamosus, fusco-subfasciatus ; antennis testaceis, scapo apice clavaque fuscis ; tibiis’

fusco-testaceis.

Long. 5-6 millim. .

Hab. Mexico, 'Temax in North Yucatan (Gaumer).

Covered with pallid fine scales which conceal the sculpture, but without sete.

Antenne very slender ; second joint of funiculus scarcely longer than the first. Thorax

about as broad as long. LElytra slender, oblong-oval, with series of large punctures

concealed by the clothing ; this is of a pale colour, but there are one or two irregular

transverse fascize darker. Male with the front and middle tibie dilated towards the

extremity, and with a very large excision on the inner side.

Gaumer obtained a large series of this species; it is variable in colour, the scales

in some examples being strongly tinged with green. ‘The absence of sete and the

peculiar tibiee of the male distinguish the species very satisfactorily from its congeners.

2. Derosomus setosus, sp. n.

Pallide griseo-squamosus, fusco-subvariegatus, setis elongatis erectis vestitus ; antennis fusco-testaceis.

Long. 53 millim,

DEROSOMUS.—CAUTODERUS. 169

Hab. Mexico (Truqui, in coll. Fry), Saltillo in Coahuila (Dr. Palmer, Wickham),

Durango (Dr. Palmer, in U.S. Nat. Mus.), Guanajuato (Sallé, Dugés), Dublan (Hay,

in U.S. Nat. Mus.).

Antenne, except the scape, only moderately long; scape extremely slender, yellow,

with the apical incrassation fuscous ; first joint of funiculus’much thickened towards

the extremity, rather longer than the following joint. Rostrum quite short, the eyes

scarcely convex. Thorax cylindric, with very deep large punctures, clothed with pale

scales and with erect, slender, black sete. Hlytra oval, moderately long, convex, with

series of rather fine punctures, clothed with pale scales, and with more or less distinct

dark marks, and with very fine, long, erect, black hairs. Legs piceous, hispid.

The long sete and the deep, definite punctures on the thorax are the prominent

characters of this species. ‘The insect seems to have been distributed by the late

E. Dugés under the MS. name of Naupactus gratus.

3. Derosomus scutellaris, sp. n.

Elongatus, niger, viridi-griseo-squamosus ; elytris fusco-subvariegatis, setis erectis vestitis ; pedibus piceis ;

antennis elongatis, testaceis, clava fusca.

Long. 6 millim.

Hab. Guatemata, Chimaltenango (Conradt).

Antenne very long, the scape passing the front margin of the thorax; second joint

of funiculus very long, but a good deal shorter than the first joint. Rostrum rather

long, nasal incision deep; eyes oval. Thorax subcylindric, about as long as broad,

covered with pallid scales that quite conceal the sculpture. Scutellum forming a black,

shining tubercle. Elytra oval, rather convex, covered with greyish-green scales, and

bearing moderately long, erect, fine hairs ; just before the middle an indefinite black

fascia, interrupted at the suture, and also with a small black spot on each behind the

middle; the strie and their punctures fine. Under surface squamose. Legs clothed

with depressed pallid setosity, but without erect hairs.

The two examples of this species are in very mutilated condition, but the species

cannot fail to be recognized on account of the peculiar scutellum.

CAUTODERUS, gen. nov.

Antenne scapo elongato, cox posteriores late distantes ; abdomen segmentis secundis et tertiis longitudine

subeequalibus.

This genus agrees fairly well with Derosomus, except that the structure of the

ventral plates is peculiar, the second segment being remarkably short, while there

appears at first sight to’be a sixth ventral plate present at the extremity of the body ;

this is, however, owing to the margins of the dorsal plate being deflexed to the ventral

surface. The scrobes appear to be rather more sharply limited than they are in

Derosomus. ‘Che absence of wings, though pretty certain, has not been verified.

170 RHYNCHOPHORA.

1. Cautoderus mexicanus, sp. n. (Tab. VII. fig. 6, ¢.)

Gracilis, griseo-viridi-squamosus, setis erectis brevissimis vestitus ; antennis testaceis, apicem versus apicibusque

articulorum fuscis.

Long. 4 millim.

Hab. Mexico (coll. Solari: 2), Cuernavaca in Morelos (Hoge: ¢).

This species is very similar to the variety of Derosomus fragilis that has the scales

tinged with green, but in C. mexicanus the elytra bear numerous very short erect sete.

The antenne are moderately long and the second joint of the funiculus is much

shorter than the first. The eyes are large and convex. The thorax is slender, sub-

cylindric, about as long as broad, a little narrowed towards the front. The elytra are

broader at the base than the thorax, and become a little wider till just behind the

middle; they are rather finely punctate-striate. ‘The legs are black, and the middle

tibie of the male bear an emargination on the inner face just above the apex. Three

specimens,

CHATOPANTUS, gen. nov.

Antenne scapo elongato, prothoracis marginem anteriorem fere attingente; coxe posteriores modice distantes ;

abdomen segmentis ventralibus primo et secundo subzequalibus, tertio multo breviore.

I am obliged to separate the species referred to this genus from Derosomus on

account of the more approximate hind coxe ; it has, too, the pleural edge of the wing-

case but little sinuate. In other characters, except that the scape is not quite so long,

Chetopantus seems to agree with Derosomus. The mentum appears to be remarkably

slender, and the labial palpi exposed at its apex excessively minute.

1. Chetopantus illustris, sp. n. (Tab. VII. fig. 7.)

Niger, viridi-squamosus, setis tenuibus erectis vestitus ; antennis fusco-rufis, basi rufo.

Long. 43 millim.

Hab. Mexico, Tacambaro in Michoacan (/ége).

Antenne with the second joint of the funiculus only half as long as the first, this

latter not nodose at the tip, but becoming gradually broader there, the other joints of

the funiculus elongate and setigerous. Rostrum short, feebly rugose, bearing brilliant

green scales, the nasal plate broad and short, its margin elevated. ‘Thorax slender, a

little rounded at the sides and narrowed in front, coarsely rugose, bearing brilliant

green scales and fine, erect sete. Scutellum small, but distinct, narrow. Elytra

slender, oval, scarcely broader at the base than the thorax, with large, closely-placed

punctures in the broad strie, bearing small brilliant green scales and numerous fine,

elongate sete. Legssetose. Under surface squamose, like the upper. Two examples.

The remains of a specimen from Sturm’s collection, labelled by him “ Polydrosus

malachiticus, mihi,” belong, I think, to this species.

AMELADUS.—SCIADRUSUS. 171

AMELADUS, gen. nov.

Antenne scapo elongato ; cox posteriores late distantes; elytra striis nono et decimo bene discretis.

This genus is proposed for a more robust insect than the species of Derosomus, and

at the same time having the body beneath destitute of scales, the eyes are round and

coarsely facetted, and the ninth and tenth strie of the elytra distinct and uninterrupted.

The nasal plate is short and has no free margin ; its surface is flat, and exhibits a fine

sculpture, giving it asilky appearance. The scrobes are visible from above, their lower

margin prominent and very abruptly defined, their upper margin indefinite. The

mentum is quite minute and leaves the maxille fully exposed. ‘The first and second

ventral segments are elongate. The claws are connate, but are larger than is usually

the case with the connate claws of the members of this group.

1. Ameladus inornatus, sp.n. (Tab. VII. fig. 8.)

Sat robustus, piceus, parce setoso-squamosus, setis crassiusculis brevibus vestitus; antennis tarsisque rufis ;

prothorace rugoso, elytris fortiter seriatim punctatis.

Long. 54 millim.

Hab. Mexico (Sallé), Jalapa, Matamoros Izucar, Puebla (//ége).

Antenne only moderately long and slender, first joint of funiculus elongate, much

longer than the second, club elongate. Rostrum short and broad; head wide; eyes

convex, circular, coarsely facetted. ‘Thorax moderately broad, rounded at the sides

and a little narrowed in front, coarsely and deeply rugose, covered scantily, like the

head, with greyish setosity intermediate between sete and scales. LElytra at the base

considerably broader than the thorax, with rather large and deep punctures placed in

rows; sparsely clothed with a greyish and fuscous setosity and bearing short, stout,

upright setze. Under surface not squamose, clothed with a few fine hairs,

SCIADRUSUS, gen. nov.

Elytra humeris sat distinctis ; ale rudimentarie adsunt.

The species constituting this genus is remarkable in that it possesses small wings

having veins, but quite useless for purposes of flight; the other characters that are

correlative with the presence or absence of wings seem also to be in an intermediate

condition in this interesting insect. The scape of the antenna does not attain the

thorax; the eyes are slightly angular in outline beneath, the scrobes are lateral and

form a regular curve quite separated from the eye. ‘The elytra are broader at the base

than the thorax; the 9th and 10th striz are distinct throughout; the scutellum is

distinct and is rounded behind; the metanotum is semichitinous; the buccal cavity is

rather large, the mentum quite small, the maxille being exposed. ‘I'he hind coxe are

not widely separated ; the first and second ventral plates are elongate, the 3rd and 4th

much shorter. The body is squamose beneath.

Sat elongatus, niger, pallide griseo (fere albido) squamosus; elytris pone medium nigro-fasciatis vel maculatis ;

setis erectis tenuibus superne ubique vestitus.

Long. 44-54 millim.

Hab. Mexico, Chilpancingo and Tepetlapa in Guerrero (H. H. Smith), Iguala

(Hoge).

Antenne not elongate; first joint of funiculus rather long, greatly longer than the

second, which differs but little from the third. Rostrum rather long and slender;

eyes oval, finely granulated. ‘Thorax hardly as long as broad, rounded at the sides

and a good deal narrowed in front. Scutellum small, but distinct. Elytra suboblong,

much broader at the base than the thorax, the striz quite fine. Legs hispid.

This species is deep black, but is covered everywhere with a peculiar fine setosity—

intermediate between sete and scales—which obscures the sculpture; this clothing is

very readily removed, and black spaces are then left ; but in addition to these abraded

spots, there appears to be a small fascia behind the middle which is naturally black.

SCIOMIAS, gen. nov.

Mentum minutissimum, a maxillis cinctum; corpus plus minusve abbreviatum, elytris convexis.

Scape of antenne slender, rather long, bare. Rostrum short, broader at tip; scrobes

visible from above, descending obliquely and directly from the insertion of the antenne,

without any previous lateral prolongation. Mentum very small, forming as it were a

shining tubercle embraced by the maxille. Prosternum in front of coxe excessively

reduced. Hind coxe only moderately distant. Body not squamose beneath. First

and second ventral plates rather elongate, the suture between them straight, or but

little angulate; third and fourth plates short. Ninth and tenth striz of elytra distinct

throughout.

This genus may be distinguished by the form of the scrobes, which, owing perhaps

to the abbreviation of the rostrum, pass directly downwards, and leave well-marked

pterygia exposed. The facies is somewhat that of the European genus Platytarsus,

but is still more like Dinas, Woll., from the Cape Verde Islands.

placed as near to the insertion of the antenne as to the front of the thorax. The

latter subcylindric, not longer than broad, very slightly rounded at the sides in the

middle, the sculpture obscured by the squamosity, which, however, is not dense.

Scutellum not distinct. Elytra convex, rising suddenly from the base of the thorax,

their base not wider than the base of the thorax, but becoming rapidly broader, much

narrowed towards the apex, so as to be acuminate behind; with series of coarse

punctures, and clothed with a white squamosity distributed vaguely into spots, and

also set with erect truncate sete. Under surface not squamose; second, third,

and fourth ventral plates armed with erect, pallid, rigid sete or bristles. Three

specimens.

Long. 37 millim.

Hab. Mexico, Omilteme, Chilpancingo (H. H. Smith).

Antenne not elongate, unicolorous, yellow ; first joint of funiculus moderately long,

stout, nearly twice as long as the second. Rostrum moderately long, a little breader

at the tip; eyes convex, coarsely facetted, placed but a short distance in front of the

thorax, very widely separated from one another. Thorax cylindric, covered with a

delicate squamosity or setosity, which, however, is not dense. Elytra convex, almost

regularly oval, with striz that are well marked and moderately coarsely punctured ;

with a fine squamosity arranged so as to give a slight variegate appearance, and with

some distant, excessively fine, rather short, erect hairs. Under surface piceous, not

squamose, bearing only a few extremely fine hairs. Five specimens.

3. Sciomias rugicollis, sp. n.

coarsely sculptured ; eyes not very widely separated, placed at a considerable interval

in front of the thorax. The latter slender, but rounded at the sides, very densely and

coarsely sculptured. Elytra oval, with very regular series of large punctures, the

interstices somewhat convex, bearing a scanty squamosity and also an exudation which

when removed brings away the scales; there are also very short, erect, truncate,

pallid seta. Two specimens.

Long. 33 millim.

Hab. Guatemata, San Gerdénimo (Champion).

This species is remarkable by the form of the elytra, which are broad and convex,

but nevertheless with the dorsum somewhat flattened. Antenne rather short, yellow,

unicolorous, second joint of funiculus small. Head and rostrum covered with scales

as far forward as the deep scrobes. Thorax small, subcylindric, deeply punctured, but

the sculpture concealed by scales, with a slight shining carina-like space on the middle.

Elytra at base just as broad as the base of the thorax, but becoming very rapidly

wider, so that the shoulders are perfectly rounded; covered with scales, which are

slightly variegate, and bearing erect, short, truncate sete. ‘Two specimens.

PARASOMUS, gen. nov.

Femora dentata. Unguiculi vix connati.

The insect for which I establish this genus much resembles the European Sciaphilt

and Eusomi, except that it is of rather shorter form ; it is distinguished from them, as

well as from the other genera of Sciaphilina found in our region, by the fact that the

claws at their bases are very narrowly separated; possibly they may prove to be

connate at their articulation within the claw-joint. Independently of this, the genus

may be identified by the dentate femora. If the claws prove to be really free, I think

the insect would be better placed in the Epicerina near Clezstolophus and the other

genera of that group with dentate femora.

The antenne are moderately stout, the scape about attaining the front margin of

the thorax. ‘The rostrum is moderately long, slightly broader at the tip, which is

provided with a small, deeply-impressed nasal plate; the eyes encroach on the front

and are oval, only slightly prominent; the scrobes are short, slightly descending,

broader behind, not nearly reaching the eye. The mentum is not broad, but fills the

buccal cavity, neither the maxille nor the palpi being exposed. The prosternum is

short, the coxe are contiguous and placed very near the front of the thorax. ‘The

metasternum is short; the first ventral segment is much longer than the second. ‘The

anterior tibiee are armed with a long slender claw at the inner apical angle. The tips

of the hind tibiz are simple; the corbels not in any degree cavernous. The under

surface is squamose.

Antenne long, moderately stout, first and second joints of the funiculus elongate,

equal, club long and rather slender. Head and rostrum densely squamose. Thorax as

long as broad, subcylindric, very slightly narrowed before and behind the middle ; densely

squamose, with some distant punctures rendered obscure by the squamosity, which is

pallid grey, fuscous along the middle, where also there is a very fine channel. Elytra

rather short, narrow, with very distinct series of punctures; with a dense squamosity,

fuscous mottled with grey in colour, and with some excessively short white sete,

which attract attention only on the declivous part. Legs rather long, all the femora

acutely dentate; the tibize and tarsi obscure red, clothed with pallid setosity. Nine

specimens.

ISODACRYS, gen. nov.

Rostrum deflexum ; pronotum elongatum ; coxe anteriores leviter distantes; tibiz anteriores denticulate.

This genus is proposed for four very small apterous Otiorhynchids having some

resemblance to Pandeleteius and various allied forms in the winged series. ‘The rostrum

is very short, provided with slender scrobes, placed laterally and abruptly bent, so as to

reach the under surface at a considerable distance from the eye; the buccal cavity is

rather small and filled by the mentum, which is broader than long; the nasal plate is

quite small; the head is broad; the eyes are round, lateral, placed a short distance in

front of the thorax; the antennz are short, the scape slender, not so long as the

width of the head between the eyes, but slightly longer than the width of the apex of

the rostrum, the funiculus very short, except its first joint, the club short, oval,

compact. Pronotum greatly longer than the prosternum. Coxe placed near the front

of the latter, and far from its base, minutely but distinctly separated from one another.

Metasternum short, hind coxe rather widely separated ; first and second ventral plates

subequal, the latter quite as long as the third and fourth together. Leys short and

stout; anterior tibiee denticulate and mucronate ; tarsal claws small, free.

Hab. Mexico (Truquz), Orizaba (Sallé, HT. H. Smith).

This species is apparently closely allied to L. guatemalenus, but the erect sete are

replaced by short white scales. In addition to this, there is a considerable difference

in form, the thorax in J. orizabe being more slender, and the elytra become abruptly

broader near the base and are acuminate behind. Nine specimens.

Antenne red, more obscure towards the apex. Rostrum rather broad; eyes widely

separated. Thorax very long, rather broad, slightly inflated in the middle, covered

with an indumentum, looking like scales, and definitely punctate. Elytra very convex

transversely but not longitudinally, scarcely broader behind the shoulders, at which

point they are just a little wider than the base of the thorax, with the suture on the

declivous part a little compressed and prominent; covered with a griseous scale-like

indumentum, which is slightly variegate; and with an obsolete striation. Five

specimens.

This interesting little insect need not be confounded with J. guatemalenus or

7. orizabe on account of the apparent absence of sete; the set are, however, really

present, but are so minute and short that careful observation is required to detect

them. The three species, nevertheless, have a common peculiarity, inasmuch as

there are one or two fine bristles on each side of the anterior margin of the thorax

in such a position as to make it proper to call them rudimentary vibrisse.

4, Isodacrys minutus, sp.n. (Tab. VII. fig. 17.)

Ferrugineus, dense squamosus, setis brevissimis vestitus ; prothorace sat elongato.

Long. 22 millim.

Hab. Mexico, Omilteme (H. H. Smith).

Antenne short, the joints of the funiculus, after the second, extremely small and

difficult to count, the club large. Rostrum very short, only moderately broad; eyes

slightly convex. Thorax slender, as long as broad, subcylindric, a little dilated in the

middle. Elytra rather narrow, a good deal rounded at the sides and shoulders, very

slightly convex longitudinally ; densely clothed with scales, and bearing minute sete,

which are only conspicuous towards the apex, where they are a little longer ; finely

striate. Legs stout. Four examples.

This tiny weevil has the pronotum rather less elongate than its congeners, thus

are no vibrisse, and the wings are almost certainly wanting.

The single genus referred by me to this group has the scrobes superior and the

tarsal claws connate, the first-mentioned character Separating it from the Sciaphilina.

THRICOLEPIS.

Thricolepis, Horn, Proc. Am. Phil. Soc. xv. p. 68 (1876).

This is a North-American genus of two species. It appears to have occurred just

within the northern limits of our region and is possibly merely an intrusion from

N. America. It is, therefore, unnecessary to discuss it further than to remark that its

distinction from Peritelus appears to me to be doubtful.

We figure this species as the sole representative of a group whose absence in our

region is most remarkable.

Group TRACHYPHLG@INA.

This group is perhaps scarcely separable from the Otiorhynchina as defined by Horn,

who refers three N.-American genera to it, two with the scrobes superior and one

with the scrobes lateral. They have comparatively short antenne, with the scape

becoming gradually thicker to the tip and sometimes reaching the front of the

prothorax, and the outer joints of the funiculus moniliform, the tarsal claws free, &c.

A single species of the typical genus Zrachyphleus is represented in the Mexican

collections before me.

armed with numerous short sete. Under surface bearing numerous short sete ;

terminal ventral plate with a large deep fovea.

We have received only one specimen from each locality: the individual from

Tehuacan is covered with an incrustation of dirt, and appears to be rather more

elongate in form, so that possibly it may represent a second species.

Series OTIORHYNCHINA ALATA*.

The characters for this Series of the Otiorhynchine are given on p. 87, anted, and

are much the same as those used by Horn for his Division II. of the N.-American

forms. The term “ Alate” unfortunately proves to be misleading, as we now know

that the wings are sometimes rudimentary even in a series of specimens of certain

species, é.g. in Tanymecus confertus, Gyll. (= variabilis, Fahr.), from the same

locality, and one or two other genera also include both apterous and winged forms.

It is proposed here to divide the species of the present series into two sections: one

without definite ocular lobes to the prothorax +, the other with the lobes large and

rounded. The first section, again, is subdivided, according to the presence { or absence

of vibrisse, the condition of the tarsal claws (connate or free), the position of the

scrobes and eyes, the lamination or otherwise of the apex of the posterior tibize (closed

or open corbels), &c. Horn’s groups [tribes] “ Tanymecini,” ‘“* Exophthalmini,” and

‘* Promecopini” are practically accepted, the last-named corresponding to our

Section II.; but his “ Cyphini,” with the much larger number of genera represented

in our region, and “ Phyllobiini ” require different treatment.

Section I.—Ocular lobes wanting or rudimentary.

Group TANYMECINA.

This group is equivalent to Horn’s Tribe “'Tanymecini,” and it includes two genera

in addition to those belonging to the N.-American fauna. Polydacrys is said by him

to have “very distinct vibrisse composed of scales,” but these longer scales seem to

me to be part of the general vestiture and not true vibrisse ; this genus, moreover,

cannot be satisfactorily placed in a different group from its close ally, Anypotactus,

in which the vibrissiform scales are wanting. The tarsal claws are free, except in

the anomalous genus Jsodrusus, which forms a connecting-link with the Polydrosina.

The essential characters of the Tanymecina, therefore, are the presence of setiform

vibrissee and the laterally placed scrobes.

* By G. C. Campton.

t+ In Pachneus and Diaprepes there is sometimes an indication of a short lobe, as in Pandeleteius and

Hadromerus.

+ Apparently wanting or replaced by scales in one or two of the smaller species of Pandeleteius of the

“ Tanymecina.”

An abundant insect in Central America, apparently not extending south of

Nicaragua, examples from our region not differing from others before me from Texas,

&c. Specimens from Paso del Norte are larger, more densely punctate, and more closely

squamose than the rest; Dr. Horn®, too, also notes larger individuals from the

Southern United States. The wings are usually in a rudimentary condition, but

occasionally become fully developed, even amongst a series examined from the same

localities (Teapa and Rio Hondo). The rostral carina is rarely obsolete. The humeri

are obliquely truncated. The first ventral segment is hollowed down the middle in

the male, the fifth is without trace of oblique lines at the base in the female. The

length varies from 5-82 millim. A male from Nicaragua is figured. The insect has

been found on Ginothera in Texas‘.

2. Tanymecus hirsutus, sp. n. (Tab. VII. figg. 21, 21a, 3.)

3. Elongate, narrow, black, the antenne and tips of the tarsi obscure ferruginous; somewhat thickly

clothed with small cinereous seales intermixed with numerous short suberect pallid sete, the sete on the

elytra closely placed and arranged in two or three rows along each interstice. Head and rostrum

densely punctate, the rostrum transversely subquadrate, slightly emarginate at the tip, and with an

abbreviated median sulcus; eyes prominent. Prothorax about as long as broad, rounded at the sides, a

little narrower at the apex than at the base, densely, uniformly punctate. Elytra elongate, wider than

the prothorax, slightly hollowed at the base, the humeri obtuse ; coarsely punctate-striate, the interstices

almost flat and closely punctulate. First ventral segment broadly hollowed down the middle, and the

fifth obsoletely sulcate towards the apex. All the tibie distinctly unguiculate at the inner apical angle.

Length 63-71, breadth 2-22 millim.

Hab. Mrxico, Guanajuato (Sallé), Obrajuelo (Flohr).

Two males, one worn. Narrower than 7. confertus; the rostrum uot carinate, but

with a short median groove; the elytra connate, closely set with short, semierect,

brownish sete, the scales scattered and not condensed into definite markings, the

humeri not obliquely truncated.

DIAPREPES.,

Diaprepes, Schéuherr, Cure. Disp. Meth. p. 116 (1826); Gen. Cure. ii. p. 7, vi. 1, p. 342 (part.).

The two species from our region referred to Diaprepes (sunk as a synonym of

Exophthalmus by Lacordaire) agree with Schonherr’s type (Curculio spengleri, Linn.,

from the Antilles) in having conspicuous vibrissee, and the genus also includes other

W. Indian forms. ‘The supposed new genus briefly characterized (but not named), and

a type indicated (Exophthalmus sommeri, Rosensch.), by Horn in 1876 (Proc. Am. Phil.

Soc. xv. p. 100) is synonymous with Diaprepes, the particular species mentioned by

him having a short angular prominence on each side of the prothorax in front (repre-

senting the true ocular lobe), much as in Pachneus. In Exophthalmus (type Curculio

quadrivittatus, Oliv.) the vibrisse are entirely wanting. In both genera the elytra

have supplementary strie on the outer part of the disc.

1. Diaprepes albofasciatus, sp.n. (Hzxophthalmodes albofasciatus, Tab. VII.

figg. 22, 22a, 3; 23, 23a, 2.)

Oblong, shining, black ; the prothorax with two narrow interrupted vittee on the disc, and the elytra with

three irregular fasciee, a transverse patch at the base, and various scattered asymmetrically arranged

spots, densely clothed with white or yellowish-white imbricate scales, the rest of the upper surface

more sparsely set with minute, brown or whitish scales and very short decumbent sete; the under

surface and legs with small bluish or white scales. Head and rostrum closely punctate, the head foveate

between the eyes, the rostrum much longer than the head, sharply carinate down the middle, and sulcate

on each side in front of the eyes. Prothorax transverse, subconical, rounded at the sides anteriorly,

more or less distinctly suleate down the middle; very sparsely, irregularly, coarsely punctate, the

interspaces minutely punctured. LElytra with rows of closely placed coarse punctures, which become

crowded and confused on the outer part of the disc below the base, the interstices almost flat, the apices

feebly acuminate, setose, and dehiscent. Tibise without denticles on their inner edge.

Length 15-17, breadth 54-74 millim. (¢ @.)

Hab. Honvuras (Mus. Brit.: 3), Belize River (Stanton, in U.S. Nat. Mus.: @ ).

Two specimens, the male labelled as having been received in 1845. In the latter

the prothoracic sulcus is sharply defined and the seriate punctures on the disc of the

elytra are very coarse. ‘The minute whitish scales on the upper surface are easily

abraded, but when present (as in the female) they give a powdery appearance to

the spaces between the markings. The deciduous portion of the mandibles is

flattened and falciform (fig. 23 a).

2. Diaprepes pulverulentus, sp. n.

Oblong, black or piceous; densely clothed with cinereous or bluish-white scales (the colour more or less

modified by an ochreous exudation), which are condensed into two vitte on the disc of the prothorax

and another along each flank (the intervening spaces appearing sparsely squamose), and a shorter or

longer stripe at the base of the alternate elytral interstices, those on the disc sometimes wanting; the

surface also set with short scattered decumbent sete, the seriate elytral punctures each with an oblong

scale. Head and rostrum densely punctate, the rostrum finely carinate, the inter-ocular fovea small or

wanting. Prothorax transverse, canaliculate down the middle; impressed with scattered foveiform

punctures intermixed with a fine interstitial punctuation. Elytra elongate-subtriangular in g, broader

and widened to the middle in 9, acuminate and mucronate at the tip, flattened on the disc anteriorly,

the disc sometimes with several scattered shallow irregularly placed fovee ; with rows of rather fine

punctures which become confused on the outer part of the disc below the base, the interstices feebly

convex. Tibi without denticles on their inner edge.

Length 133-18, breadth 43-74 millim. (¢ 2.)

Hab. Nicaracua, Chontales (Belt).

Five specimens, varying greatly in size, as well as in the colour of the scales, which

is disguised by an ochreous exudation. The vibrisse are easily abraded, and are

wanting in two examples. ‘This insect is less convex than D. albofasciatus, the

rostrum is more finely carinate, and the vestiture is much denser over the whole surface.

A genus including a few species from the Antilles and Florida, one of which has

been recorded from Mexico, but this locality seems to require confirmation. They

are all of rather large size, and densely, uniformly clothed with whitish, pale yellow,

blue, or green opaque scales. The prothorax is strongly bisinuate at the base in

—~&P, opalus and P. litus, more feebly so in P. distans, and the anterior margin also

is sinuate on each side beneath, and the vibrissee are well developed.

A genus containing some of the most beautiful known American winged Otiorhyn-

chids, H. dejeant, gemmifer, opalinus, &c., being more or less densely clothed with

glittering metallic scales. In a few forms, however, the scales vary greatly in colour

and may even become uniformly whitish or cinereous in the same species. The

females of all of them have the suture of the elytra set with long erect hairs towards

the apex, and the males a small claw at the inner apical angle of the intermediate

tibie. The type of Hadromerus is H. nobilitatus, Gyll. One of the Guatemalan

forms has been found in numbers in the ‘tierra fria.”

The seven Central-American forms may be tabulated thus :-—

a. Surface closely squamose, the legs included, the femora (except in immature

examples) at least black.

Very like A. dejeani, but differing as follows:—Rostrum slightly longer, more deeply hollowed down the

middle, appearing rather sharply carinate on each side above; the antennal club more elongate; the

elytra relatively longer, with similarly coloured scales, the bare spots on the interstices extremely small

in 9, larger, numerous, and conspicuous in d¢, the suture set with long hairs towards the tip in @ ; the

This insect is apparently common in the Los Altos region of Guatemala (between

6000 and 9000 feet) and it has long been known under Jekel’s MS. name of

H. scintillans. ‘The scales are coloured and beautifully scintillate as in H. dejeani,

from which the present species is separable by the more deeply excavate rostrum and

the longer antennal club. Four specimens only have been seen from Mexico, and the

2. Hadromerus dejeani. (‘Tab. VII. fig. 27, 2.)

Hadromerus dejeanii, Boh. in Schénh. Gen. Cure. vi. 1, p. 293".

Moderately elongate, black; densely clothed with rather large, subimbricate, glittering intermixed green

and golden scales, with blue and cupreous reflections, and also set with fine, scattered, inconspicuous

erect hairs, which become longer on the apical declivity of the elytra, the suture with longer hairs

towards the apex in 9. Head and rostrum together about as long as the prothorax, the rostrum

canaliculate and broadly flattened or feebly depressed down the middle; antennal club about as long

as joints 1-5 of the funiculus, the two basal joints of the latter subequal in length. Elytra rather

finely seriate-punctate, the interstices each with from three to five rows of scales and with a scattered

irregular series of very small, bare, smooth spots. Legs densely squamose and pilose; anterior femora

subangulate before the apex within; anterior tibie sharply unguiculate in ¢, more feebly so in 9, the

intermediate pair also with a small claw in ¢.

Length 7-9, breadth 24-4 millim. (¢ 9.)

Hab. Mexico (Mus. Brit.), Playa Vicente, Cordova (Hoge), Jalapa (U.S. Nat. Mus.),

El Camaron (Sallé), Vera Cruz 1.

Of this species, the type of which has been compared with the examples from

El Camaron in the Sallé collection by Dr. Sharp, we have received a long series from

Playa Vicente. There is very little variation in the general colour of the scales, which

are so large as to be subimbricate, though they are a little smaller on the elytra in the

g than in the 2. ‘The fine sete on the upper surface are conspicuous on the apical

declivity only. Boheman also gives! California as a locality, probably in error.

8. Hadromerus micans, sp.n. (Tab. VII. figg. 28, 28a, 2.)

. Elongate, rather broad, black; densely clothed with small, scintillating, green and golden scales, with

cupreous and bluish reflections, and also set with fine, scattered, long, erect hairs, which become still

longer along the suture towards the apex. Head and rostrum together about as long as the prothorax,

the rostrum canaliculate and moderately excavate; antenne with joint 2 of the funiculus a little longer

than 1, the club as long as 3-7 united. Prothorax very finely, closely punctate. Elytra long and

broad, subparallel, flattened on the dise anteriorly, with prominent tumid humeri; finely seriate-punctate,

the interstices flat, each with from five to seven closely packed rows of scales, and with a series of

rather large, somewhat closely placed, polished, glabrous spots. Legs densely squamose and pilose;

anterior tibiee denticulate and sharply unguiculate.

This variable insect is generally placed as a form of H. dejeani in collections, from

which it differs in the smaller scales on the upper surface and the more abundant fine

scattered setosity. In most of the specimens the scales are uniformly green or

cupreo-cinereous ; but in the short series from Chiapas nearly all the colour-varieties

are to be found, including several with intermixed scintillating metallic scales or the

elytra faintly maculate. I have not seen an example from Arizona. ‘The equally

variable S.-American H. gemmifer is very like H. opalinus, but it has larger bare

smooth spots along the elytral interstices.

erect hairs, those along the posterior half of the suture long and setiform. Head and rostrum together

about as long as the prothorax, the rostrum canaliculate and moderately excavate; antenne with

joint 2 of the fuviculus slightly longer than 1, the club elongate. Prothorax closely, finely punctate.

Elytra comparatively short and broad, rather convex, the fine seriate punctures almost hidden by the

densely placed scales, the interstices flat, each with an irregular scattered row of from six to eight,

subangular, glabrous, smooth, slightly raised spots. Legs densely squamose and sparsely pilose; anterior

tibiee strongly unguiculate and denticulate.

This Mexican insect has long been known under one or the other of the above-

quoted MS. names. It is more densely squamose and a little less elongate than

Hf. opalinus and H. scintillans, and the small scales are uniformly coloured (though

variable in tint) and not scintillate when viewed in different lights. Two examples

only have been seen with whitish squamosity, one of them having been found at the

same locality (Cuernavaca) as others with golden-green scales. The minute bare spots

on the elytral interstices, when present, are not larger than the seriate punctures.

7. Hadromerus rufipes, sp.n. (Tab. VII. figg. 34, 34a, 9.)

©. Elongate, shining, black, the antenne (the club excepted) and legs ferruginous ; clothed’ along the sides

(above and beneath) with scattered, iridescent, golden-green and blue scales, the scales on the upper

surface clustered into several small spots on the prothorax and a longitudinal sinuous stripe down the

dise of each elytron, the two stripes becoming coalescent at the commencement of the apical declivity ;

the under surface and legs also with scattered pallid hairs, the suture of the elytra with several very long

erect hairs towards the tip. Head and rostrum together abcut as long as the prothorax, the rostrum

deeply emarginate at the apex, canaliculate, feebly depressed down the middle, and finely punctate ;

joints 1 and 2 of the funiculus equal in length. Prothorax very sparsely, finely punctate. LHlytra

broad, elongate, flattened on the disc; with rows of fine scattered punctures, the interstices flat,

alutaceous, and sparsely, minutely punctured, the space occupied by the long sinuous stripe somewhat

depressed. Legs very sparsely, finely punctured, sparsely pilose, and with a few scattered metallic

scales ; anterior tibise unguiculate and feebly denticulate.

Length 134, breadth 5 millim.

Hab. Costa Rica, Arcangeles 1700 metres (Biolley).

One example. A remarkably distinct form, distinguishable at a glance by its

186 RHYNCHOPHORA.

This genus appears to have its headquarters in Mexico, whence a large number of

species are now described, extending northward into the United States and southward

into the Windward Is., Colombia, &c. ‘The type is the N.-American P. hilaris,

Herbst (=pauperculus, Gyll.). It is connected with Hadromerus by P. erubescens,

mainly differing from that genus by the less approximate anterior cox. ‘The species

here referred to Pandeleteius have a 7-jointed funiculus, very stout anterior femora,

and denticulate anterior tibie *. The vibrisse are not visible in one or two of

the smaller forms (as already noted by Schaeffer), but they may be abraded or repre-

sented by small scales; and the scrobes vury in length, according to the species.

Those with a deep transverse inter-antennal sulcus on the rostrum, or a long second

joint to the funiculus, might perhaps be eliminated, but they are connected by inter-

mediate forms. Menetypus (type, M. hadromeroides, Kirsch, from Colombia) only

differs from Pandeleteius in the wide sense in having rather more sharply denticulate

anterior tibie f. The females of several species have the elytral suture set with long

erect hairs or seta towards the apex (as in Hadromerus), and in P. armatus there is

also a sharp oblique tooth on its inner edge near the tip. The wings seem to be fully

developed in all of them.

The numerous species may be distinguished thus :—

a. Scrobes descending to lower margin of rostrum.

1. Pandeleteius erubescens, sp.n. (Tab. VII. fig. 35, 2.)

Elongate, piceous, the antenns {the club excepted) and tarsi more or less ferruginous ; densely clothed above

with intermixed golden-green and blue scintillating scales, the head and rostrum, the margins of the

prothorax narrowly, the base and apex of the elytra, and a transverse subtriangular patch on the outer

half of the disc just beyond the middle, the legs, and under surface cupreous, the scales beneath whitish

in one specimen ; the surface also set with minute, scattered, decumbent, hair-like scales, those on the

elytra uniseriately arranged down each interstice. Head and rostrum about as long as the prothorax,

the rostrum deeply emarginate at the tip, canaliculate and shallowly depressed down the middle, the

median groove terminating anteriorly in «a transverse sulcus, the nasal plate triangular, the scrobes long

and descending; eyes prominent ; antenne with joint 2 of the funiculus slightly longer than 1, the club

as long as 8-7 united. Prothorax not so long as broad, rounded at the sides, constricted in front and

narrowed behind; vibrisse long. Elytra much broader than the prothorax, moderately elongate,

subparallel in ¢, widening to the middle in 9, flattened on the disc, acuminate and dehiscent at the

tip, the bare, interlocking, coriaceous lower margin of the suture thus being exposed for a short distance ;

finely punctate-striate, the interstices flat. Anterior tibiz unguiculate and feebly denticulate, moderately

long in the two sexes.

Length 73-84, breadth 22-32 millim. (¢ @.)

Hab. Costa Rica, Savanillas de Pirris (Underwood: 2); Panama, Volcan de Chiriqui

3000 feet (Champion: ¢ ).

One pair, the male somewhat immature and with conspicuous seriate punctures on

the elytra. The sculpture of the surface is almost completely hidden in the female by

the dense vestiture. This beautiful insect is clothed with glittering metallic scales,

like Hadromerus scintillans and its allies, but the anterior coxe are well separated

and the species therefore cannot be included in Hadromerus. ‘The transverse inter-

antennal groove is deep.

PANDELETEIUS. 189

2. Pandeleteius boops, sp.n. (Tab. VIII. figg. 1, La, b, ¢.)

Elongate, piceous or obscure ferruginous, the tibie ferruginous; densely, uniformly, clothed with rather

coarse pale brown or whitish scales. Head and restrum together slightly longer than the prothorax,

the rostrum short, broad, hollowed down the middle, deeply emarginate at the tip, and with a sharply-

defined transverse groove between the points of insertion of the antenne, the scrobes angulate and

descending ; eyes very prominent ; antenne rather long and slender, joint 2 of the funiculus scarcely

shorter than 1, 3-7 decreasing in length, the club as long as 4-7 united. Prothorax transverse,

subcylindrical, feebly constricted at the base and before the middle, closely, finely punctate; vibrissx

long. Elytra long, much broader than the prothorax, widening to the middle, strongly so in Q,

transversely depressed at the base, the sutural angles subacuminate and almost contiguous ; punctate-

striate, the interstices 3, 5, and 7 raised, except on the disc anteriorly. Legs rather slender, the anterior

pair elongated; anterior femora abruptly clavate; anterior tibie bowed at the tip, sharply unguiculate,

and armed with about 6 minute teeth.

Length 53-6, breadth 13-23 millim. (¢ @.)

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

One pair. This insect has the vestiture uniformly coloured as in P. tibialis, but

differs from it (and from the Colombian Menetypus hadromeroides, Kirsch, also*) in

having a transversely sulcate rostrum, prominent eyes, a long second joint to the

funiculus, a subcylindrical prothorax, &c.

3. Pandeleteius femoralis, sp. n.

Moderately elongate, piceous, the legs in great part ferruginous; densely clothed with opaque whitish and

pale brown scales, the latter condensed on the elytra into several irregular more or less confluent spots

(one near the suture towards the apex and two on the fourth interstice below the base more conspicuous.

than the rest, the scales on the interstices 1-3 almost wholly white to far beyond the middle). Head

and rostrum together a little shorter than the prothorax, the rostrum broad, widening outwards (as seen

from above), canaliculate and slightly hollowed, deeply emarginate at the tip, the nasal plate triangular

and margined behind, the scrobes descending to the lower margin ; antenns: with joints 1 and 2 of the

funiculus equal in length, the club long; eyes very prominent. Prothorax about as long as broad,

produced in front, rounded at the sides, strongly constricted at the base and before the middle, coarsely

punctate (as seen abraded); vibrisse long. Elytra moderately long, a little broader than the prothorax,

gradually widening to the middle, transversely depressed below the base ; finely punctate-striate, the

alternate interstices slightly raised posteriorly, the suture abruptly declivous on the apical declivity.

Anterior femora enormously developed, very strongly clavate. Anterior tibie long, curved at the tip,

strongly unguiculate, and armed with 6 small equidistant teeth.

Length 44, breadth 14 millim. (@.)

Hab. Mexico (Mus. Lrit.).

One rather abraded specimen, injured by pinning, but with the left elytron intact

and the scales undisturbed. ‘his is one of the two examples from the Jekel collection

representing the Mexican P. ‘idialis in the British Museum, and the locality perhaps

requires confirmation. The insect, however, may readily be known by the enormously

developed, very strongly clavate anterior femora, the elongate second joint to the

funiculus, the very prominent eyes, the deeply cleft apex of the rostrum, and the

faintly maculate outer half of the elytra. P. femoralis may prove to be of Colombian

origin, but it is undescribed in any case.

slender, the anterior femora strongly and abruptly clavate; anterior tibiz elongate, curved at the apex,

unguiculate, and armed with from 4-6 minute sharp teeth ; intermediate tibise hollowed towards the apex

within, the posterior pair also hollowed in ¢.

Length 3-33, breadth 1-14 millim. (¢ @.)

Panama, Bugaba, Volcan de Chiriqui (Champion).

_ Twelve specimens—two from Costa Rica, in very fresh condition (taken as the types),

three from Guatemala, smaller and paler, and seven from Chiriqui, all worn. <A small,

submetallic form, with peculiar elytral markings (including a common -shaped patch

towards the apex), a transversely sulcate rostrum, descending scrobes, prominent eyes,

strongly clavate anterior femora. &c. The vibrisse are apparently wanting, perhaps

owing to the dense clothing of scales. The tarsal claws are free. The v-shaped ridge

bordering the nasal plate is similar to that of Pol; ydacrys depressifrons.

Nine specimens, all but one from Guatemala. A narrow, robust, obscurely variegate

form, very like a Sitones, thickly set with short, curled, decumbent, dark, setiform

hairs, which are equally distributed along each elytral interstice, and with the legs

stout and the anterior tibiz comparatively short.

8. Pandeleteius crispus, sp.n. (Tab. VIII. tigg. 6, 6a, ¢.)

Elongate, robust, subcuneiform, piceous, the antenne and tips of the tarsi ferruginous; densely clothed with

Hab. Mexico, Amula in Guerrero (H. H. Smith), Parada in Oaxaca (Sal/é).

Four specimens, probably all males, the one from Parada smaller than the others.

This insect may be known by its elongate, somewhat cuneiform shape, the long, stout,

curled sete on the alternate elytral interstices, the descending scrobes, and the sub-

truncate anterior margin of the rostrum.

9. Pandeleteius cucullatus, sp. n.

Moderately elongate, subcuneiform, obscure ferruginous or ferruginous ; densely clothed with pale brownish

scales, the prothorax with a faint median vitta and the elytra with two indistinct, oblique, darker brown

P. crispus, but with the elytral sete extremely short and inconspicuous (as in

P. varicolor), the rostrum more deeply emarginate at the tip, the prothorax faintly

trivittate. The less clavate anterior femora, the relatively longer prothorax, and the

differently marked elytra separate P. cuneatus from P. varicolor. ‘The specimens with

conspicuously hollowed intermediate tibiz are assumed to be males.

basal half, wider than the prothorax ; punctate-striate, the alternate interstices raised, more distinctly

setose and wider than the rest, the others feebly convex. Anterior femora strongly clavate. Anterior

tibi comparatively short and stout, feebly unguiculate, and set with five sharp teeth. Intermediate

tibie excavate towards the apex within.

in part due to abrasion), a subtubulate, variegate prothorax, comparatively short

anterior tibia, &c. The elytra are shaped as in P. hirtipes; the short, rather stout

sete are a little longer and more numerous on the alternate interstices than on the

others.

13. Pandeleteius hispidus, sp.n. (Tab. VIII. figg. 10, 10 a.)

Moderately elongate, widened posteriorly, ferruginous; variegated with a dense clothing of pale brown,

blackish-brown, and whitish scales, the dark scales on the prothorax condensed into a narrow median

vitta, and those on the elytra into a narrow undulate subapical fascia and a few small scattered spots,

the whitish scales on the prothorax mainly placed along the sides, and those on the elytra condensed

into a narrow streak at the base of the fifth interstice, a transverse mark on the disc before the middle,

and a common, angulate, sharply-defined fascia before the apex ; the upper surface also somewhat thickly

set with short, curled, stout, decumbent sete, which are uniseriately arranged on the alternate elytral

interstices, the suture with longer setee towards the apex ; the under surface albo-squamose. Head and

rostrum together a little shorter than the prothorax, the rostrum very short, shallowly emarginate at the

tip, the scrobes deep, sinuous, and descending; eyes depressed. Prothorax a little longer than broad,

produced in front, constricted at the base and before the middle, sparsely punctate ; vibrisss represented

by a densely squamose dentiform prominence. Elytra much broader than the prothorax, widening to

the middle, finely punctate-striate, the alternate interstices somewhat raised. Legs rather stout,

setose ; anterior femora moderately clavate ; anterior tibiee curved, stout, slightly elongated, unguiculate,

and armed with 4 small teeth.

Length 33-47, breadth 13-14 millim.

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

Three specimens, A small, comparatively short, posteriorly widened form, with

stout, curled, decumbent sete (conspicuous on the frons and alternate elytral inter-

stices), a fusco-vittate prothorax, apically albo-fasciate elytra, deep descending scrobes,

rather short, setose legs, and the vibrisse represented by an angular densely squamose

prominence. Its nearest ally is P. brevipes.

14. Pandeleteius brevipes, sp.n. (Tab. VIII. fig. 11.)

Oblong, piceous or obscure ferruginous ; variegated with a dense clothing of rather coarse brown, blackish-

brown, and whitish scales, the whitish scales mainly condensed into a narrow sinuous stripe on each

side of the prothorax, an oblique spot or patch on the outer part of the disc of the elytra just before the

middle and a common sinuate subapical fascia, and the dark scales sometimes into a transverse scutellar

patch and a narrow angulate fascia in front of the whitish one, the upper surface also set with short,

curled, decumbent hairs, the legs annulate. Head and rostrum together much shorter than the

prothorax, the rostrum very short, strongly transverse, flattened, feebly emarginate at the tip, the scrobes

descending ; eyes somewhat prominent. Prothorax rather longer than broad, produced in front, feebly

constricted at the base and before the middle, sparsely punctate; vibrisse reduced to a few scales.

Elytra comparatively short, much broader than the prothorax and widened posteriorly (9 ), or narrower

and subparallel (3); coarsely punctate-striate, the alternate interstices more or less raised. Anterior

femora clavate. Anterior tibie scarcely elongated, stout, bowed at the tip, feebly unguiculate, closely,

very finely denticulate.

Length 2-42, breadth 1-13 millim. (¢ 2.)

Hab. Mexico, Amula, Xucumanatlan, and Omilteme in Guerrero (H. H. Smith),

Mexico city, Yautepec (//dge).

Nine specimens, five of which are from Amula, the narrow examples assumed to be

males. This species resembles P. ornatifrons, but it is smaller; the rostrum is still

shorter; the head is without the angular white patch; the eyes are not so prominent ;

the prothorax is less constricted at the sides; the vibrisse are reduced to a few scales;

and the elytra are more coarsely punctate-striate.

15. Pandeleteius conspersus, sp.n. (Tab. VIII. figg. 12, 12 a.)

Moderately elongate, widened posteriorly, ferruginous; clothed with intermixed, rather coarse, brown and

whitish scales, the latter condensed into small scattered spots or patches, the prothorax in one specimen

(taken as the type) with the sides albo-squamose, like the under surface; the upper surface also

set with exceedingly minute, short, curled, scattered hairs, the suture of the elytra with several long

erect hairs towards the tip. Head and rostrum together shorter than the prothorax, the head small,

the rostrum extremely short, feebly emarginate, and with a short median groove, the scrobes descending;

eyes prominent, small, Prothorax a little longer than broad, rounded at the sides, feebly constricted

at the base and before the middle, closely punctate; vibrisse not visible (? abraded). Elytra much

broader than the prothorax, widened to beyond the middle, transversely depressed below the base;

coarsely punctate-striate, the interstices convex. Anterior femora strongly clavate. Anterior tibis

elongated, curved, unguiculate, and armed with 6 very small teeth.

Length 32-4, breadth 12-13 millim. (2.)

Hab. Mexico, Chilpancingo in Guerrero (H. 4. Smith).

Two specimens, one in good condition, the other somewhat worn, doubtless females,

to judge from the long erect hairs on the elytral suture towards the apex. The

extremely short rostrum, with deep descending scrobes, the prominent eyes, the

intermixed arrangement of the brown and white scales (the white scales in one

specimen being confined to the sides of the prothorax, and to small scattered irregular

patches along the sides and apical half of the elytra), and the long, finely denticulate

anterior tibize are the chief characters of P. conspersus. P. quichensis is a somewhat

similar form, with less rounded sides to the prothorax, non-descending scrobes,

sinuous, less closely denticulate anterior tibiz, and fewer intermixed white scales.

apex, subparallel in ¢, widened towards the middle in 9 ; finely punctate-striate, the interstices flat

on the disc, convex towards the sides and apex, the suture set with long, fine, scattered hairs towards

the apex in 9. Anterior coxe subcontiguous in 3, more distantin Q. Anterior femora very stout,

clavate. Anterior tibiee very long and slender, curved at the tip, sharply unguiculate, ciliate, and armed

with numerous small teeth. Anterior tarsi elongate. Intermediate and posterior legs slender. Tarsal

claws long.

Length 54-74, breadth 13-23 millim. (¢ 2.)

Hab. Mexico (coll. Sommer}; Mus. Brit.), Ventanas in Durango (Hége), San Andres

Tuxtla, Yolos, Capulalpam, Parada (Sallé), Oaxaca (Mus. Brit., Hoge).

The types of this species from the Sommer collection have been lent us by Mr. Janson.

It is easily recognized by the greatly elongated anterior legs, the uniform brownish-

white vestiture, the basally and apically constricted prothorax, the deeply emarginate

rostrum, and the long claws. ‘The anterior coxe of the male are almost as approximate

as in Hadromerus. The abraded specimens before me have the body piceous and

the legs red.

17. Pandeleteius hirtipes, sp. n. (Tab. VIII. figg. 14, 14a, ¢.)

3. Elongate, rather convex, robust, dull, piceous, mottled and streaked with ferruginous ; variegated with

a dense clothing of small, pale brown and whitish scales, which have a cupreous tinge in certain lights,

and also set with very short, scattered, adpressed hairs, the anterior coxe, the underside of the rostrum,

and the prosternum clothed with very long pallid hairs, the rest of the under surface also thickly pilose.

Head and rostrum sparsely punctate, the rostrum very short, flattened, feebly emarginate, strongly

canaliculate, the scrobes short ; eyes not prominent. Prothorax transversely convex, much broader than

rather sparsely punctate, the convex portion sharply canaliculate; vibrisse long. Elytra long, sub-

parallel, not wider than the prothorax, transversely depressed below the base, abruptly declivous behind ;

punctate-striate, the interstices more or less convex, the alternate ones a little more raised than the

others, the third tumid at the base. Anterior femora very stout, clavate. Anterior tibie long, bowed

inwards towards the apex, closely ciliate, unguiculate, and armed with numerous small teeth ; intermediate

and posterior tibie feebly denticulate and closely fringed with long hairs in their apical half, the

intermediate pair with a small claw. Tarsi hairy, the anterior pair elongated.

also occurring at Ciudad.

PANDELETEIUS. 197

18. Pandeleteius inflatus, sp. n. (Tab. VIII. figg. 15, 15a.)

Geniostomus inflatus, Jekel, in litt.

Oblong-piriform, robust, piceous, the tips of the tarsi and the antenne ferruginous; variegate with small

pale brown, fuscous, and whitish scales, which have a cupreous lustre in certain lights, the brown scales

condensed into a small triangular patch at the base of the head and two faint sinuous stripes on the

disc of the prothorax; the whitish scales on the elytra sometimes condensed into a conspicuous sub-

quadrate patch on the disc before the middle and various oblong, subquadrate, confluent patches on the

apical declivity, and the intervening spaces on the disc fusco-maculate; the ventral surface pilose and

clothed with rather large iridescent scales. Head and rostrum sparsely punctate, the rostrum very

short, transverse, flattened, and canaliculate, feebly emarginate and fringed with long bristly hairs in

front; eyes not prominent. Prothorax about as long as broad, feebly constricted at the base and

towards the apex, moderately rounded at the sides, somewhat produced in front; closely punctate ;

arcuately dilated thence to the middle, and with the apices rather broadly conjointly produced ;

punctate-striate, the interstices feebly convex throughout. Anterior tibie moderately long, unguiculate,

and armed with numerous small teeth.

Length 72-8, breadth 33-31 millim. (9 ?)

Hab. Mexico (Mus. Brit.; Solari, ex coll. Jekel), Omilteme in Guerrero (H. H.

Smith).

Three specimens, the one from Omilteme wanting the conspicuous subquadrate

whitish patch on each elytron. A species easily identified by its broadly dilated,

moderately convex elytra, the transverse, shallowly emarginate rostrum, and the feebly

constricted, subtubulate prothorax.

19. Pandeleteius laticeps, sp.n. (Tab. VIII. figg. 16, 16a, ¢.)

Moderately elongate, robust, piceous, the legs and antenne in part ferruginous; variegated with a dense

clothing of brown, fuscous, and cinereous scales, the cinereous scales condensed into a faint transverse

fascia on the outer part of the disc just before the middle and showing a tendency to form a large apical

patch, the brown scales with a brassy or cupreous tint, the under surface with scattered hairs between

the scales. Head large, broad, together with the rostrum nearly as long as the prothorax, the rostrum

transverse, flattened, narrowly sulcate, emarginate at the tip, the nasal plate short, triangular, the scrobes

narrow, short, and deep; eyes not prominent, somewhat oval. Prothorax a little broader than long,

convex, rounded at the sides, abruptly constricted at the base and also constricted anteriorly, closely

punctate; vibrissee long. Elytra much broader than the prothorax, subparallel at the base, gradually

widened to the middle, transversely depressed anteriorly, abruptly declivous at the apex in 2 ; punctate-

striate, the alternate interstices somewhat convex, 3 tumid at the base. Anterior femora clavate.

Anterior tibiz moderately long, curved at the tip, unguiculate and armed with about 7 small teeth.

Hab. Mexico, Orizaba (Fenyes, ex coll. Bovie), Cerro de Palmas (Hége), Sierra de

Ajusco (Hay, in U.S. Nat. Mus.).

Four specimens, two of which are in bad condition. Very like some of the varieties

of P. maculicollis, but easily separable therefrom by the larger and broader head, and

the more convex prothorax.

198 RHYNCHOPHORA.

20. Pandeleteius armatus, sp.n. (Tab. VIII. figg. 17, 174, 4, 2.)

Moderately elongate, flattened above, opaque; fuscous, variegated with testaceous, the antenne, tarsi, and

apex of the elytra almost wholly of that colour, the deciduous mandibles rufescent; mottled with a

dense clothing of whitish, pale brown, and fuscous scales, the dark scales on the prothorax condensed

into a broad median vitta, which is bordered on each side by a whitish stripe, the elytra with an oblong

whitish spot on the fifth interstice at about the basal third and another on the sixth a little nearer the

base; the upper surface also set with short, scattered, curled, adpressed, inconspicuous hairs, the suture

of the elytra in @ with a cluster of very long, erect, pallid hairs at the commencement of the apical

declivity and another at the tip. Head and rostrum together about as long as the prothorax, finely

punctate, the rostrum triangularly emarginate at the tip, depressed at the base, and canaliculate down

the middle; eyes prominent. Prothorax strongly transverse, rounded at the sides, abruptly and deeply

constricted anteriorly, narrow at the base; finely punctate, obsoletely canaliculate, the disc transversely

‘depressed before and behind the middle; vibrisse long. Elytra much broader than the prothorax,

transversely depressed below the base, widening to beyond the middle, the humeri prominent ; finely

punctate-striate, the interstices becoming convex posteriorly ; the apices narrowly and obtusely produced

in ¢, and armed on the inner edge with a sharp, inwardly-directed, spiniform prominence in 9

(fig. 17). Anterior femora strongly clavate. Anterior tibize moderately long, feebly curved, unguiculate,

and armed with from 6-8 small teeth.

Length 52-6, breadth 21-24 millim. (¢ 9.)

Hab. Mexico (Truqui, in coll. Fry ; Mus. Oxon.).

Two females and two males, the latter immature, all more or less injured by pinning.

The armature of the sutural margin of the elytra of the female (no doubt for

effectually locking them in repose) is suggestive of the male structures found in

various Melyrids. P. armatus superficially resembles P. ciliatipennis.

91. Pandeleteius ornatifrons, sp.n. (Tab. VIII. figg. 18, 18 a.)

Oblong, piceous, the legs and antenne in part ferruginous; variegated with a dense clothing of pale brown,

blackish-brown, and cinereous or whitish scales, the whitish scales condensed into a sharply-defined

triangular or a-shaped mark on the vertex of the head (sometimes extending forward on to the rostrum)

and two transverse fascie on the elytra (one just before the middle, not reaching the suture, the other

subapical and oblique), and the dark scales clustered into one or three vittee on the prothorax, a common

transverse mark at the base of the elytra and a very large saddle-shaped patch between the pale fascia,

the pale brown scales with a cupreous tinge; the upper surface and legs also sparsely set with short,

curled, decumbent hairs, the legs annulate. Head comparatively small, together with the rostrum

shorter than the prothorax, the rostrum short, hollowed and canaliculate, shallowly, triangularly

emarginate ; eyes prominent. Prothorax nearly as long as broad, rounded at the sides, strongly con-

stricted at the base and before the middle, sparsely punctate; vibrissee reduced to a few long hairs.

Elytra much broader than the prothorax, widening to the middle, and more or less inflated posteriorly

(2 ?), transversely depressed below the base; finely punctate-striate, the interstices feebly convex.

Anterior femora clavate. Anterior tibia moderately long, curved, unguiculate, and armed with 4 or 5

_ small teeth.

Length 43-6, breadth 2-23 millim.

Hab. Mexico, Chilpancingo and Omilteme in Guerrero (H. H. Smith).

Ten specimens. Recognizable by the prominent eyes; the comparatively small,

albo-maculate head; the small, bi-constricted prothorax ; and the sharply albo-fasciate

elytra, with a common transverse dark patch at the base, which is connected along

the suture with the saddle-shaped post-median band. The less hairy prosternum, the

PANDELETEIUS. 199

more prominent eyes, &c., separate P. ornatifrons from P. maculicollis. A narrower

and smaller example from Chilpancingo seems to be a male of the same species.

22. Pandeleteius viridiventris, sp. n. (Tub. VIII. fig. 19.)

Moderately elongate, rather narrow, opaque, fusco-testaceous or ferruginous, faintly maculate with black :

above clothed with small coppery-brown and larger cinereous scales, the latter clustered into sinuous

interrupted lines on each side of the prothorax and various small irregular spots along the sutural and

apical regions of the elytra, and in one specimen condensed into a large apical patch; the upper surface

also set with minute, curled, adpressed hairs; the lower surface (the abdomen excepted), and the

anterior femora beneath, clothed with opalescent pale greenish scales. Head and rostrum together

shorter than the prothorax, finely punctate, the rostrum very short, flattened and finely canaliculate,

emarginate at the tip; eyes rather prominent, small, rounded. Prothorax about as long as broad,

produced in front, constricted at the base and (more feebly so) towards the apex, sparsely punctate ;

vibrissee represented by two or three hair-like scales. Elytra wider than the prothorax, subparallel,

transversely depressed below the base; finely punctate-striate, the alternate interstices somewhat

raised towards the apex. Anterior femora clavate. Anterior tibie slightly elongated, sinuous within,

curved at the tip, unguiculate, and armed with 6 small denticles.

Length 33-4, breadth 13-14 millim.

Hab. Mexico, Tres Marias in Morelos (Wickham).

Three specimens, one abraded, recently received from their captor. A small, narrow,

somewhat depressed form not unlike P. brevipes, with shorter scrobes, finely punctured

elytral strize, much finer curled hairs on the upper surface, &c. ‘The prothorax is less

constricted, and the anterior tibie more feebly sinuate within, than in P. stnuatipes.

23. Pandeleteius quichensis, sp. n.

Elongate, narrow, dull, ferruginous, obsoletely maculate with black; clothed with small coppery-brown and

larger widely scattered cinereous scales, the latter condensed into interrupted sinuous lines on each side

of the prothorax and various minute irregularly distributed spots on the elytra. Head, rostrum, eyes,

and prothorax as in P. viridiventris. Elytra much wider than the prothorax, subparallel, transversely

depressed below the base; coarsely punctate-striate, the alternate interstices slightly raised posteriorly.

Anterior tibiz sinuous within, armed with 4 or 5 minute denticles.

Length 34-44, breadth 13-14 millim.

Hab. GuateMALA, Quiché Mts. (Champion).

Two specimens, somewhat worn. Relatively longer than P. brevipes, the elytra

subparallel, the cinereous scales on the elytra clustered into minute scattered spots.

From P. viridiventris the present species may be distinguished by the more coarsely

punctate-striate elytra.

24, Pandeleteius quadrinodosus, sp. n.

Moderately elongate, piceous or fusco-ferruginous ; variegated with a dense clothing of pale brown, blackish-

brown, and cinereous or whitish scales, the dark scales condensed into two sinuous lines on the disc of

the prothorax and two or three oblique interrupted fasciee on the outer part of the disc of each elytron,

the spaces between the fascie sometimes with a few whitish scales; the surface also set with minute,

curled, scattered, adpressed hairs, the legs annulate. Head small, together with the rostrum scarcely

convex portion slightly depressed across and down the middle, and more or less distinctly 4-nodose ;

vibrissee moderately long. Elytra much broader than the prothorax, widening to the middle, transversely

depressed at the base; punctate-striate, the aiternate interstices interruptedly raised, 3 tumid at the

base. Anterior femora strongly clavate. Anterior tibie moderately long, curved at the tip, unguiculate,

and armed with 4 small teeth.

Length 43-53, breadth 17-24, millim.

Hab. Guatemata (Dus. Brit.), near the city, Purula (Champion), Volcan de Fuego

(Salvin).

Six specimens. This species is nearly related to P. maculicollis, from which it may

be distinguished by the quadrinodose prothorax and the subparallel upper portion

of the rostrum. The head is-‘small as in that insect, and the prosternum is sparsely

pilose.

25. Pandeleteius brevinasus, sp. n. (Tab. VIII. figg. 20, 20a.)

Very like P. maculicollis, but differing as follows :—Rostrum subtriangular (as seen from above), rapidly,

Yy g ,

obliquely narrowing before the eyes, and with the apical portion still shorter and less dilated at the tip,

the scrobes curved, deep, and extending a little further downward; the prothorax less constricted at the

sides anteriorly, shallowly sulcate; the elytral interstices somewhat convex, 1 and 5 sometimes a little

raised, 3 tumid at the base.

Length 5-63, breadth 2,4,-24 millim.

Hab. Mexico (Mus. Dresden), Puebla (Sallé), Omilteme and Chilpancingo in

Guerrero (H. H. Smith), Cerro de Palmas, Yautepec, Jalapa (Hége); GuatemaLa

(Mus. Brit.), Calderas 7000 feet (Champion).

Fourteen specimens, all but two from Mexico. Apparently distinct from the

variable P. maculicollis, the subtriangular, extremely shorter rostrum giving P. brevi-

nasus a peculiar facies when the insect is viewed from in front. The markings of the

elytra are very similar in the two species. An example from Omilteme is figured.

26. Pandeleteius maculicollis, sp.n. (Tab. VIII. figg. 21, 21a, 4, 2.)

Pandeleteius maculicollis, Jekel, in litt.

Moderately elongate, piceous or fusco-ferruginous; variegated with a dense clothing of brown. blackish, and

cinereous scales, the dark scales on the elytra often condensed into one broad or two narrower, incom-

plete, transverse fascie, and the cinereous scales into a large irregular or interrupted apical patch and a

transverse space on the dise between the fascixw, the brown scales usually cupreous in certain lights ;

the upper surface also set with minute, scattered, short, adpressed hairs, the prosternum and anterior

coxee with numerous long white hairs arising from between the scales, the rest of the under surface more

sparsely pilose. Head comparatively small, together with the rostrum shorter than the prothorax, the

rostrum transverse, obliquely narrowed before the eyes and widened again at the apex, feebly canali-

culate, shallowly emarginate at the tip, the scrobes subangulate, short ; eyes depressed, oval. Prothorax

broader than long, transversely convex, rounded at the sides, constricted anteriorly and at the base,

usually obsoletely sulcate down the middle posteriorly, closely punctate; vibrissw long. Elytra broader

than the prothorax, widening to beyond the middle, transversely depressed below the base, and more or

less inflated posteriorly; punctate-striate, the interstices 1 (suture), 3, and 5 usually raised or

eariniform from about the basal third, 3 always more or less tumid at the base. Anterior femora

strongly clavate. Anterior tibie moderately elongated, curved, sinuate towards the apex, unguiculate,

and feebly denticulate.

Length 43-61, breadth 2-24 millim. (d 9.)

Hab. Mexico (Mus. Brit. ; U.S. Nat. Mus.), Ciudad in Durango (forrer), Omilteme,

Chilpancingo (H. H. Smith), Ixtapan, Parada (Sal/é).

A widely distributed, variable Mexican insect, with a hairy prosternum, as in

P. hirtipes. Some specimens have the alternate elytral interstices strongly raised and

the suture abruptly declivous posteriorly. The five from Ciudad (taken as the types,

fig. 21) have a large cinereous apical patch and the alternate interstices scarcely

prominent. The cinereous scales sometimes predominate. One of the examples in

the British Museum is much narrower than the rest and has subparallel elytra.

27. Pandeleteius fasciatus, sp.n. (Tab. VIII. figg. 22, 22 a.)

Pandeleteius fasciatus, Jekel, in litt.

Moderately elongate, robust, ferruginous or obscure ferruginous ; variegated with a dense clothing of brownish-

white and brown scales, the darker scales condensed into a median stripe or three vitte on the prothorax

and numerous, transverse or oblique, partly confluent markings on the elytra (these sometimes extending

over half the surface and almost surrounding two oblique, sharply defined, pallid fasciz) ; the surface also

set with scattered, minute, curled, decumbent hairs. Head and rostrum together about as long as the

prothorax, the rostrum transverse, flattened, and triangularly emarginate, the scrobes not extending

beyond the eyes, the latter depressed. Prothorax about as long as broad, rounded at the sides, constricted

towards the apex and at the base, sparsely punctate; vibrisse long. Elytra broader than the prothorax,

widened to the middle, somewhat inflated posteriorly; finely punctate-striate, the interstices becoming

convex towards the sides and apex. Anterior femora strongly clavate. Anterior tibie long, feebly

curved, unguiculate, and armed with about six scattered teeth.

Length 41-62, breadth 13-23 millim. (¢ ¢.)

Hab. Mexico (Mus. Brit.), Jalapa, Cerro de Palmas, Oaxaca (Hoge) ; GUATEMALA

(Mus. Brit.), San Geronimo (Champion), Chinautla (Sallé).

Numerous examples, few of which, however, are in good condition. ‘The elytra

vary greatly in colour, according to the predominance of the light or dark scales, the

darker specimens only having conspicuous oblique pallid fascie. ‘The complete basal

constriction of the prothorax and the shorter scrobes readily separate P. fasciatus from

P. cucullatus and P. cuneatus, both of which, moreover, have strongly setose legs, less

clavate femora, a more produced prothorax, and raised alternate elytral interstices.

98. Pandeleteius undatus, sp.n. (Tab. VIII. fig. 23, 2.)

Moderately elongate, obscure ferruginous ; densely clothed with brown scales, the prothorax broadly paler at

the sides (leaving a distinct darker median vitta), the elytra with a transverse or oblique patch on the

outer part of the disc at about the middle, and a common, undulate, sharply-defined, subapical fascia,

whitish or pale brown; the surface also set with a few very minute, adpressed, curled hairs. Head and

rostrum together about as long as the prothorax, the rostrum triangularly emarginate; eyes depressed,

Prothorax about as long as broad, constricted at the base and towards the apex; vibrisse long. Elytra

long, unguiculate, and armed with 5 or 6 small scattered teeth. Intermediate tibiz hollowed near the

apex within in ¢.

Length 54, breadth 24-23 millim. (d 2.)

Hab. Guatemaua, San Gerénimo [ 2 ], Capetillo [| ¢ |] (Champion).

Three specimens, assumed to be sexes of the same species, the female (taken as the

type, fig. 23) being much broader than the Capetillo examples (males ?) and in very

fresh condition. They all have a common, sharply-defined, undulate, whitish, subapical

fascia, but the transverse patch on the disc varies in size, though very conspicuous in

the female. The Capetillo specimens have slightly larger scales than the San

Gerdénimo insect. The curled hairs on the upper surface are smaller, shorter, and

much less conspicuous than in P. fasciatus when the two forms are viewed in profile.

The elytral markings, too, in P. fasciatus show no tendency to coalesce into a common,

well-defined, pallid, subapical fascia.

29. Pandeleteius vitticollis, sp.n. (Tab. VIII. fig. 24.)

Moderately elongate, piceous or obscure ferruginous, the legs and antenne partly or entirely rufo-testaceous ;

variegated with a dense clothing of opaque whitish, pale brown, and fuscous (or blackish) scales, some of

which have a faint cupreous lustre in certain lights, the dark scales on the prothorax almost wholly

condensed into a broad median vitta, and those on the elytra into a narrow, oblique or angulate, subapical

fascia (followed by a broader whitish one) and various irregular scattered spots or streaks; the upper

surface also set with scattered, very minute, short, curled hairs, which are uniseriately arranged down

each elytral interstice. Head and rostrum together about as long as the prothorax, finely punctate, the

rostrum subquadrate, triangularly notched at the tip, slightly hollowed and feebly canaliculate down the

middle, and with a very shallow transverse inter-antennal groove, the scrobes curved, narrow, and

not descending to the lower surface; eyes somewhat prominent; joint 2 of the funiculus not longer

than 3 and 4 united. Prothorax transverse, rounded at the sides, strongly constricted towards the apex,

and constricted and much narrowed behind; sparsely punctate, the disc transversely depressed before

and behind the middle; vibrisse long. LElytra at the base considerably wider than the base of the

prothorax, widening to the middle and inflated posteriorly, strongly so in 9, transversely flattened on

the disc anteriorly ; finely punctate-striate, the interstices becoming convex towards the apical declivity,

Anterior tibie long, slender, feebly curved, unguiculate, armed with about 8 small teeth. Intermediate

and posterior legs slender.

Hab. Mexico (Mus. brit.), Refugio in Durango, Cordova (Hége), Amula (H. H.

Smith); GuarEMALA, near the city (Salvin, Champion), Capetillo, San Gerdnimo, San

Joaquin (Champion); Nicaragua, Managua (Solari); Panama, Volcan de Chiriqui

(Champion).

Numerous examples, including a long series from San Gerdénimo. This species may

be known by the arcuately dilated, basally and apically constricted, fusco-vittate

prothorax; the posteriorly widened, obliquely unifasciate, fusco-maculate, finely

punctate-striate elytra; the long, slender, feebly curved anterior tibia ; and the slender

intermediate and hind legs. The single example from Panama is much smaller than

the others. P. vitticollis may prove to be inseparable from P. robustus, Schaeff., from

PANDELETEIUS. 203

Arizona (a single specimen of which is before me), but the latter has the elytra less

inflated posteriorly and not so sharply fasciate, and the scrobes broader and less

curved.

30. Pandeleteius amula, sp. n.

Moderately elongate, depressed, obscure ferruginous; thickly clothed with opalescent whitish scales, the

elytra with several faint, scattered, transverse, almost bare spots, which tend to form an interrupted

oblique subapical fascia. Head and rostrum together about as long as the prothorax, finely punctate,

the rostrum flattened, obsoletely canaliculate, and very slightly hollowed, deeply triangularly emarginate

at the tip; eyes not prominent, rather large. Prothorax a little broader than long, rounded at the sides,

constricted at the base and towards the apex, finely punctate: vibrisse long. Elytra flattened, a little

broader than the prothorax, gradually widening to the middle, subtruncate at the base ; conspicuously

punctate-striate, the interstices feebly convex. Anterior femora strongly clavate. Anterior tibie

elongated, moderately curved, unguiculate, and armed with 7 small teeth.

Length 5, breadth 1? millim. (¢ ?)

Hab. Mexico, Amula in Guerrero 6000 feet (ZZ. H. Smith).

One specimen, somewhat immature, and with the deciduous falcate portion of the

mandibles still attached. This species is clothed with opalescent whitish scales only,

much as in P. albisquamis (the darker partly bare spaces on the elytra may be accidental),

from which it differs in its depressed form, larger eyes, biconstricted prothorax, the

truncated base of the elytra, &c. From P. robustus the present species may be known

by its immaculate, less uneven prothorax, the flatter, narrower, obsoletely maculate,

non-setulose elytra, and the opalescent scales; and from P. ¢¢dialis by the less prominent

eyes, &c.

31. Pandeleteius sublineatus, sp.n. (Tab. VIII. fige. 25, 25a, 2.)

Moderately elongate, widening posteriorly, varying in colour from piceous with the antenne (the club

excepted) and tibia ferruginous to wholly ferruginous; densely clothed with rather coarse brown and

whitish scales, the brown scales on the prothorax condensed into a broad median vitta and an interrupted

submarginal streak, and those on the elytra into a common, elongate, scutellar patch and various faint

interrupted lines, the line of whitish scales on each side of the disc of the prothorax usually more or less

distinctly continued along the third elytral interstice and sometimes condensed into a large oblique apical

patch ; the upper surface also sparsely set with extremely minnte, curled, adpressed hairs, the apex of

the rostrum and the under surface with opalescent whitish scales. Head and rostrum together nearly

as long as the prothorax, the rostrum longer than broad, hollowed and faintly canaliculate, emarginate

at the tip, the nasal plate triangular ; eyes somewhat prominent. Prothorax as long as broad, narrowed

and constricted at the base and also constricted anteriorly, finely punctate ; vibrissee long, Elytra much

broader than the prothorax, widening to the middle in both sexes; abruptly declivous behind, finely

punctate-striate, the interstices feebly convex. Legs slender, the anterior femora very stout and strongly

clavate ; anterior tibie long, curved, unguiculate, and armed with about 6 minute teeth.

the third interstice, the anterior tibiz long, curved, and ferruginous. Three specimens

found by Mr. H. H. Smith in the Windward Is. seem to belong to this species.

Moderately elongate, narrow, ferruginous, faintly maculate with black, the under surface darker, the legs

testaceous; clothed with small coppery-brown and larger cinereous scales, the latter mainly placed along

the sides and base of the prothorax, and those on the elytra clustered into definite dark-edged spots—

three across the disc before the middle and several forming an irregular oblique fascia near the apex ;

the upper surface also sparsely set with minute curled decumbent hairs, the under surface with whitish

scales. Head and rostrum together shorter than the prothorax, the rostrum very short, hollowed and

canaliculate, shallowly, triangularly emarginate at the tip; eyes rather large, oval, not prominent.

Prothorax about as long as broad, produced in front, rounded at the sides, constricted at the base and

towards the apex, sparsely punctate; vibrisse very fine. Elytra much broader than the prothorax, slightly

widened towards the middle, transversely depressed below the base ; finely punctate-striate, the interstices

feebly convex, 3 tumid at the base. Anterior femora clavate. Anterior tibie moderately elongate, strongly

sinuate, unguiculate, and armed with 4 very small scattered teeth.

Length 42, breadth 14 millim.

Hab. Mexico, Chilpancingo in Guerrero (//. H. Smith).

One specimen, slightly immature. The chief characters of this insect are, the

comparatively large, oval eyes; the biconstricted prothorax; the moderately long,

strongly sinuate, sparsely denticulate anterior tibiz; and the tumid base of the third

elytral interstice. The dark-edged cinereous spots on the elytra partly enclose a large,

common, immaculate, cupreo-squamose space.

206 RHYNCHOPHORA.

36. Pandeleteius nodifer, sp. n. (Tab. VIII. figg. 29, 29 a, 4, 2.)

Moderately elongate, narrow, piceous or ferruginous; variegated with a dense clothing of small whitish and

brown scales, the latter condensed into a broad faint median vitta on the prothorax and a strongly

oblique, irregular, subapical fascia and various faint scattered spots on the elytra. Head and rostrum

Hab. Nicaracua, Lago de Managua (Solari).—Co.oms1a (Mus. Brit.).

The above description is mainly taken from a fresh example kindly given us by

Signor Solari, apparently a female. The Colombian specimen (¢ %) is narrower,

discoloured, and broken, but it no doubt belongs to the same species, which may be

known by the compressed prominence on the suture of the elytra towards the tip,

and the long, oval, almost unimpressed prothorax. P. nodifer superficially resembles

Menetypus hadromeroides, Kirsch.

37. Pandeleteius longicollis, sp.n. (Tab. VIII. figg. 30, 30a.)

Elongate, rather narrow, ferruginous, the antennal club and anterior femora piceous ; thickly and uniformly

clothed with whitish scales, the prothorax with a faint darker median line. Head and rostrum

together a little shorter than the prothorax, the rostrum excised at the tip and canaliculate down the

middle, the nasal plate triangular; antennal club large, acuminate-ovate; eyes depressed. Prothorax

slightly longer than broad, gradually narrowed towards the base and apex, the basal constriction

extending across the disc, the apical margin truncate; finely punctate; vibrissee long. Hlytra wider

than, and about two and one-half times the length of, the prothorax, subparallel in their basal half,

finely punctate-striate, the interstices almost flat, the suture tumid towards the apex. Anterior femora

very stout, clavate. Anterior tibia curved, moderately elongate, unguiculate,-and armed with from 6-8

small teeth. Intermediate tibie hollowed near the apex within. Tarsi with the bilobed. third joint

Two specimens. This insect has the vestiture uniformly whitish (as in P. tcbialis

P. nodifer), the elytra thus appearing relatively short; and the third tarsal joint

broadly lobed.

PANDELETEINUS, gen. nov.

Head very large, broad, convex ; mentum small, not covering the maxilla ; rostrum strongly transverse, deeply,

triangularly emarginate at the sides and apex, the scrobes rather short, angulate, distant from the eyes,

the latter small and rounded ; antennal scape reaching to the middle of the eyes, the funiculus 7-jointed,

joints 2-7 short; vibrissee well-developed ; anterior coxe contiguous; anterior femora feebly clavate, not

longer than the others; anterior tibie unguiculate at the apex, not or obsoletely denticulate ; tarsal

claws free; body robust, winged, densely clothed with scales.

Type, Pandeletejus submetullicus, Schaeffer.

The type of this genus was provisionally referred to Pandeleteius by Schaeffer, but

it must certainly be removed therefrom, differing as it does in numerous points of

structure. ‘The head is greatly developed, recalling that of Alissa and various other

genera of the “Series Aptere”; the prothorax is somewhat cup-shaped; and the

elytra are broader than the prothorax, comparatively short and subparallel, and finely

punctate-striate. The insect is found on juniper, according to Mr. Wickham.

Length 33-4, breadth 13-14 millim.

Hab. Norta America, Beaver Co., Utah +, Los Angeles, California?, Bright Angel,

&c., Arizona’, Texas.—Mexico, Tepehuanes in Durango (Wickham).

Mr. Wickham has recently sent us examples of this peculiar little insect from Utah

and Northern Mexico, agreeing with others from California and Arizona forwarded

by Mr. Schwarz, of the U.S. National Museum. The scales in some of the specimens

are uniformly coloured, greenish or golden, in others cinereous and faintly mottled

with brown above and metallic beneath.

The following description was drawn up many years ago by Dr. Sharp and requires

no alteration :—

ISODRUSUS, gen. nov. [Sharp].

Rostrum brevissimum, deflexum; coxe anteriores modice distantes.

Rostrum not so long as broad, strongly inflexed, narrower towards the tip; scrobes deep, slender, abruptly

angulate, descending. Thorax elongate; front cox distinctly separated, placed very near the front

margin, at a considerable distance from the hind margin; vibrisse represented by two or three sete.

Metasternum not elongate, as long as the first ventral plate. First and second ventral plates equal in

length, third and fourth equal, short. Legs stout; tarsal claws small, connate.

This genus resembles Polydacrys and Pandeletetus in many respects, and still

more Jsodacrys in the apterous series, but all these three genera have free claws.

Tsodrusus is altogether a most anomalous little insect; the rostrum could scarcely be

shorter, and I do not see any trace of a nasal plate atits apex. The wings (Tab. VIII.

fig. 326) are folded transversely, but have remarkably few veins. A _ similar

rudimentary condition of the vibrissz occurs in Pseudelissa and in Jsodacrys.

208 RHYNCHOPHORA.

1. Isodrusus debilis, sp. n. [Sharp]. (Tab. VIII. fige. 32, 32a; 326, wing.)

Subdepressus, ferrugineus, squamosus, setis recurvatis adspersus; prothorace elongato; elytris basi thorace

latiore, seriatim punctatis.

Long. 23-3 millim.

Hab. Guatemata, San Gerdnimo (Champion).

Antenne very short, joints 3-7 of the funiculus quite small, club moderate.

Rostrum strongly deflexed, even a little inflexed; front of the head armed with

numerous curved bristles. ‘Thorax elongate and slender, a little dilated in the middle,

squamose, and armed with curved sete. Scutellum very small, but distinct. Elytra

rather slender and flat, much broader at the base than the thorax, densely squamose,

the scales presenting an imperfect maculated appearance of pale grey and fuscous ;

with series of punctures much obscured by the squamosity, and bearing fine, recurved,

recumbent sete. Legs short, strongly setose. Under surface red, but nearly covered

with large pallid scales.

Four specimens were obtained of this species, one of which has been sacrificed to

make certain the condition of the wings. The insect bears a great resemblance to the

species of Jsodacrys, but the form of the elytra distinguishes it at a glance.

Group POLYDROSINA.

Under this group—the first of those with both ocular lobes and vibrisse wanting—

are placed Polydrusus, Germ. (= Cyphomimus, Horn), which proves to be well repre-

sented within our region, and an allied genus, with basally connate tarsal claws, a

slender, apicaliy thickened antennal scape, and the articular surface of the posterior

tibie terminal. Horn included Cyphomimus in his heterogeneous Tribe Phyllobiini,

with Phyllobius (which has differently placed, short, subterminal scrobes), Mitosty/us

(which is apterous and belongs to the Sciaphilina of Sharp, anted, p. 167), and

Scythropus, the last-mentioned genus being nearly allied to Polydrosus. Mitostylus

extends to Lower California, and probably into our region also; Scythropus is

holarctic,

No true winged Polydrosus seems to have been described from Tropical America,

and but two from the United States (P. americanus, Gyll., the type of Cyphomimus,

POLYDROSUS. 209

and P. ochreus, Fall); two species, however, are known from I.ower California. The

eleven forms now added from within our limits are closely related to some of those

inhabiting the Palearctic region, P. longicornis, indeed, being a near ally of P. pterygo-

malis, Boh. ‘The basally connate claws is perhaps the best character by which to

distinguish Polydrosus from most of the allied genera, and the sharply defined, narrow

scrobes separate it from Phyllobius. ‘The antenne are extremely slender in most of

the forms here described; the femora are unarmed; and the scrobes vary in length

according to the species, sometimes extending to the lower surface of the rostrum.

These insects attack Quercus, Salix, Alnus, Corylus, &c., and many more species will

doubtless be found to occur in the New World *. The Central-American forms may

be tabulated thus :—

a. Antenne long, the outer joints of the funiculus oblong or obconic, the scape

short, broad, inflated elytra, &c. ‘The markings vary according to the predominance of

the light or dark scales, but the elytra always have a common dark undulate median

fascia, followed and preceded by a suturally interrupted light one. The deciduous

portion of the mandibles is short, curved, and acute. P. americanus, Gyll., has some-

pale brown scales, the elytra with various paler spots, which are clustered into two interrupted fasciee—

one, oblique, at about the middle of the disc, the other undulate and subapical, the lower surface with

opalescent scales. Rostrum constricted behind the points of insertion of the antenne, the nasal plate

very short, angular, the scrobes deep, descending to about as far as the lower level of the eyes, the latter

large and prominent. Antenne slender, moderately long, joint 2 of the funiculus much shorter than 1,

Seven specimens, varying a little in the development of the scattered, asymmetrical,

partly denuded spots on the elytra. A small, graceful form, with golden-green scales,

and long, slender, pallid antenne and legs. It approaches the European P. ptery-

gonalis, Boh., and belongs to the section Hustolus, Thomson.

4. Polydrosus mutabilis, sp.n. (Tab. IX. figg. 4, 3; 5, 2, var.)

Very like P. longicornis, but with the green scales less shining and sometimes largely (as in two of the three

specimens from Panama) replaced by others of a pale cupreous tint (leaving only a streak along the inner

margin of the eyes and one or two spots on each elytron green), or with cupreous scales intermixed, the

prothorax with two or three lines or streaks, and the elytra with various scattered irregular spots,

fuscous in the examples with green scales ; the metasternum and abdomen with a very broad space down

the middle free from scales. Eyes very large. Prothorax narrower than the head with the eyes, cylin-

drical. Llytra slightly widening to the middle in ¢, very broad and inflated in 2. Intermediate

tibise without visible uneus in ¢.

Length 35-474, breadth 14-1? millim. (d 9.)

Hab. Costa Rica, Piedras Negras, Tucurrique (U.S. Nat. Mus.: 9); Panama,

Caldera in Chiriqui, San Lorenzo (Champion: 3 2).

Six examples—four with green scales predominating, the others (including the male

selected as type) with the green scales clustered into one or two small patches on each

elytron. ‘The still larger eyes (especially in the male) and the broader and more

inflated elytra sufficiently distinguish P. mutabilis from the more northern P. longi-

cornis, apart from any difference in the colour of the scales. ‘The very broad non-

squamose space beneath is clothed with extremely fine scattered hairs.

5. Polydrosus partitus, sp.n. (Tab. IX. fig. 6, 2.)

Oblong, obscure ferruginous, the antenne and legs testaceous; thickly clothed with small golden-green and

pale brown scales, the former condensed into two vitte on the disc of the prothorax and three more or

less distinct oblique fascie on each elytron; the under surface with pale green scales, almost bare down

the middle. Rostrum constricted behind the points of insertion of the antenne, the nasal plate very

short, arcuate, the scrobes short, angular, and deep. Antenne very slender, moderately iong, the scape

about reaching the front of the prothorax; joint 2 of the funiculus a little shorter than 1, 3-7 slightly

decreasing in length. Prothorax transverse, subcylindrical, about as wide as the head with the eyes.

narrow, descending to a little bencath the eyes, the latter large and prominent ; antenne long and

slender, joint 1 of the funiculus elongate, 2 much shorter than 1, 3-7 slightly decreasing in length.

Prothorax subcylindrical, constricted anteriorly, transverse, about as wide behind as the head with the

eyes. Elytra subparallel in their basal half in ¢, broader and widened to the middle in 2; finely

punctate-striate, the interstices feebly convex. Legs slender; anterior and intermediate tibie distinctly

unguiculate at the apex. Penis-sheath of the ¢ narrow, parallel-sided, rounded at the tip.

Length 34-4, breadth 13-13 millim.

Hab. GuatEMALa, near the city (Salvin), San Gerdénimo (Champion).

Six examples, one only in fresh condition. Near P. longicornis, but with the vesti-

ture less shining, the scrobes narrower and longer, the antenne and legs less elongate,

the elytra uniformly clothed with golden-green scales. PP. delicatulus, Horn, from

Lower California, is a somewhat similar form, with smaller eyes, descending scrobes,

a more transverse prothorax, shorter limbs, &c,

7. Polydrosus macrocephalus, sp.n. (Tab. IX. figg. 8, 8 a, 3.)

Elongate, narrow (¢), broader (@ ), black, the antenne ferruginous, with the apex of the scape and the

Hab. Mexico (Mus. Arit.), Iguala in Guerrero ([6ge).

One male and two females, one of the latter with most of the scales on the upper

surface discoloured and of an obscure cinereous tint. Differs from all the other forms

here described in its long head and prominent humeri. The elongate legs and antenne

separate P. macrocephalus from P. acuminatus. The single example (2?) in the

POLYDROSUS. 213

British Museum was received in 1863; it is labelled “ Phyllobius grypsatus, Schonh.,

punctate-striate, the interstices somewhat convex. Legs elongate.

Length 54-6, breadth 23-22 millim.

Hab. Mexico, “ Sierra de Durango” (Hoge, ex Solar?).

Two specimens, one abraded. Larger than any of the other species of the genus

here described, the elytra long, inflated, and acuminate, the prothorax small and sub-

conical, the antennze comparatively stout, the scrobes descending, the body elongate-

piriform in shape, perhaps narrower in the male U

9. Polydrosus chlorogaster, sp.n. (Tub. IX. figg. 10, 10a, 2.)

2. Elongate, piceous, the antenne (the black club excepted) and legs ferruginous; the sides of the head,

prothorax, and elytra, and the under surface densely clothed with metallic green scales, the upper surface

with coppery-brown scales to near the apex, the dark space on the elytra sharply detined laterally,

Length 54, breadth 13 millim.

Hab. Guatemata, Quiche Mts. 7000-9000 feet (Champion).

One specimen. A peculiar form, approaching the Palearctic P. fuscoroseus, Desbr.,

with the scales on the upper and under surfaces very differently coloured, the coppery-

brown space above extending from the tip of the rostrum to near the apex and

‘angularly excised posteriorly.

10. Polydrosus acuminatus, sp.n. (Tab. IX. figg. 11, Ll ¢.)

Oblong, piceous, the antenne ferruginous or testaceous at the base; densely clothed, the legs included, with

metallic green scales, the upper surface also set with very short, fine, suberect, pallid hairs, those on the

uniseriate punctate. Legs rather short.

Length 33, breadth 12 millim. (92?)

Hab. Mexico, Amula in Guerrero (H. H. Smith).

One specimen. This insect looks more like a Phyllobius than a Polydrosus, but it

has the scrobes lateral, angular, and deep. The legs and antenne are comparatively

short, the prothorax broad and strongly transverse, and the pallid erect sete very

conspicuous.

POLYDROSODES, gen. nov.

Head subconical, the exposed portion as long as the rostrum, the latter dilated anteriorly and slightly longer

than broad, the scrobes lateral, short, and deep; eyes large, oval, distant from the prothorax ; antenne

very slender, long; mentum rather large, covering the maxille; prothorax conical, deeply bisinuate at

drosus, with the prothorax and elytra deeply sinuate at the base, the scutellum very

small, and the body conico-elongate in shape.

POLYDROSODES,—ANYPOTACTUS. 21

1. Polydrosodes conicus, sp.n. (Tab. IX. figg. 13, 13 a.)

Black, the antenne in part ferruginous; uniformly clothed above and beneath, the legs included, with small

greyish-green scales, and also set with minute short hairs. Rostrum parallel-sided above to near the

apex, the nasal plate short, with a v-shaped ridge behind. Joint 1 of the funiculus elongate, about one-

half longer than 2, 3-7 gradually decreasing in length. Prothorax rather convex, the obliquely con-

verging sides in a line with those of the head. Elytra elongate, widening to beyond the middle, finely

punctate-striate, the interstices faintly, irregularly, uni- or biseriate-punctate.

Length 54, breadth 2 millim.

Hab. Mexico (ex coll. Jekel).

One specimen, kindly presented to us by Signor A. Solari. It must have been

captured many years ago, but there is no reason to doubt the Mexican habitat,

similarly labelled examples of other species having been found in various collections

from Mexico.

Group ANYPOTACTINA.

This group includes a few Tropical-American forms related to the Polydrosiua, but

with the tarsal claws free. They have the articular surface of the posterior tibie

terminal or slightly ascending ; the anterior tibize serrulate or unarmed on their inner

edge; the femora clavate, toothed in Anypotactus, unarmed in the other genera; the

prothorax without definite setiform vibrisse; the mandibles with a conspicuous

truncated process in front in Polydacrys, wanting in the other genera; the mentum

moderately broad or small, incompletely covering the maxille ; the rostrum with a

sharply-defined triangular nasal plate, except in Prepodellus, where it is very short and

inconspicuous ; and the wings fully developed.

ANYPOTACTUS.

Anypotactus, Schonherr, Gen. Cure. vi. 1, p. 299 (1840) ; Lacordaire, Gen. Col. vi. p. 71.

The type of this genus is A. evtlis, Boh., and a second species was subsequently

added by Faust. Anypotactus is closely related to Polydacrys, but differs from it in

having the femora sharply toothed, the rostrum concave at the sides above (leaving

the descending scrobes partly exposed in the dorsal aspect), and the scape of the

antenne reaching to the front of the prothorax. The mandibles are without a definite

truncated process in front.

1. Anypotactus bicaudatus, sp.n. (Tab. IX. figg. 14, l4a, 2; 15, ¢ .)

Moderately elongate, piceous or obscure ferruginous; densely clothed with brown scales, the elytra with a

common, paler or cinereous, subapical fascia preceded by a narrow curved black band, and some blackish

and cinereous markings on the rest of their surface ; the upper surface also set with numerous blunt,

stiff, suberect sets, which are uniseriately arranged down each elytral interstice, the legs setulose.

Head and rostrum together a little longer than the prothorax, finely punctate, the rostrum constricted

and shallowly grooved between the antennz and with a curved, transverse groove at the base, the nasal

plate transversely triangular; eyes prominent, large; antenne long, joints 1 and 2 of the funieulus

216 RHYNCHOPHORA.

subequal in length, the scape reaching beyond the front of the prothorax. Prothorax subcylindrical,

narrow, about as long as broad, finely punctate. LElytra much broader than the prothorax, gradually

widening to the middle in 9, transversely depressed at the base; punctate-striate, the interstices

somewhat convex. Anterior femora with a rather long slender tooth, the other femora feebly dentate.

Anterior tibiw long, curved, sharply unguiculate.

3. Fifth ventral segment excavate in the middle at the apex, and with a long, stout, blunt, tooth-like

process on each side of the emargination.

Length 41-44, breadth 14-2 millim. (d 92.)

Hab. Costa Rica, Turrialba (U.S. Nat. Mus.: 2); Panama, Volcan de Chiriqui,

Pefia Blanca 3000 feet (Champion: 3 9).

Three males and three females, varying in the colour of the scales, one of the

specimens being almost uniformly brown. Extremely like the Venezuelan A. sulci-

collis, Faust (for a female of which we are indebted to Dr. Heller); but differing

from it in the basally constricted upper portion of the rostrum, the non-sulcate

prothorax, and the strongly bicaudate fifth ventral segment of the male *.

Smaller (length 3-34 mm.) and less elongate than A, bicaudatus and A. sulcicollis ;

the sete on the upper surface very short and inconspicuous; the antenne shorter ;

the rostrum constricted at the base as in A. bicaudatus (as seen in profile); the

prothorax transverse; the elytra each with a large, transverse or triangular, dark

patch on the outer part of the disc just beyond the middle, followed by a broad

whitish fascia and sometimes preceded by a small pallid spot; the femora not so

stout, each with a small tooth. I am unable to distinguish the male from the female

in the long series before me, including the Colombian type.

ELumerus, Jekel, in Mus. Brit.

The species of this genus, the type of which is P. modestus, Gyll., from Cuba, may

be known by the following characters :—

Mandibles with a truncated process in front (bearing the deciduous piece), usually extending beyond the apex

of the rostrum ; rostrum with a sharply-defined triangular nasal plate limited behind by a v-shaped

POLYDACRYS. 217

ridge or groove, which is produced into a short carina or groove posteriorly, the scrobes descending to

the lower surface ; funiculus 7-jointed; scape not reaching beyond the eyes, the latter large; mentum

rather large, almost covering the maxille; vibrissee wanting or indistinguishable from the general

vestiture* ; anterior coxse very narrowly separated; femora abruptly clavate, unarmed, the anterior

pair stouter than the others; tibis setose, the anterior pair unguiculate and serrulate, the articular

surface of the posterior pair open and slightly ascending ; body oblong, squamose and setose, fully

winged.

Polydacrys and Anypotactus seem to me to be more nearly related to Polydrosus

than to Pandeleteius ; one species, however, here referred to the latter (P. hiero-

glyphicus) has a similar nasal plate to the rostrum, but in that insect (as usual in

Pandeleteius) the intermediate and posterior femora are comparatively slender and

not clavate. The five Central-American species of Polydacrys, one of which is an

abundant insect down to as far south as Costa Rica, may be tabulated thus :—

a, Second joint of funiculus shorter or not longer than first; elytra with stiff

suberect sete.

Negras (U.S. Nat. Mus.).—Antiuuzs, Grenada and St. Vincent.

A common Central-American insect replaced southward by allied forms. It is very

variable in size, and in the colour of the vestiture, according to the predominance of

the light (cinereous or pale brown) or dark (blackish) scales. P. nubilosus * was based

upon a pallid, faintly maculate, feebly setose example, and P. depressifrons (the type

of which I have seen) upon a darker, sharply marked, strongly setose insect. In the

latter the elytra have a black post-median fascia followed by an oblique white band,

both of which are sometimes reduced to an oblong streak on each elytron. In the

three specimens from Zapote the dark scales predominate, leaving scattered oblong

cinereous spots on the elytra, somewhat as in the Antillean P. modestus. The sete

are suberect and arranged in a single scattered series down each elytral interstice ;

in some specimens they are quite short. The two basal joints of the funiculus are

subequal in length.

2. Polydacrys seriegranosus, sp. n. (‘Tab. IX. fig. 18, 2.)

Polydacrys seriegranosus, Jekel, in litt.

Moderately elongate, piceous or nigro-piceous, the antenns partly or entirely ferruginous ; clothed with small

brown and whitish or cinereous scales, the latter condensed on the elytra into an oblique, more or less

distinct, subapical fascia and one or two spots on the middle of the disc, the prothorax sometimes with

a faint pallid line on each side; the upper surface also set with numerous stiff, suberect, blunt, light and

dark sete, which are uniseriately arranged down each elytral interstice, the legs strongly setose. Head

and rostrum densely punctate, together a little longer than the prothorax, the head with a short sulcus

between the eyes, the nasal plate almost smooth and limited behind by a very prominent v-shaded ridge,

which is produced posteriorly into a short carina; eyes convex ; joint 2 of the funiculus slightly shorter

than 1. Prothorax nearly as long as broad, somewhat widened at the middle; closely, finely punctate

and granulate. Elytra gradually widened to the middle and there nearly twice as wide as the prothorax,

the apices conjointly produced into a compressed, blunt, dentiform prominence at the sutural angle

(2? wanting in ¢); coarsely punctate-striate, the punctures transverse, the interstices feebly convex and

each with a series of smooth, scattered, prominent granules. Anterior tibiz bowed at the apex, sharply

unguiculate and serrulate.

Length 54-7, breadth 2-24 millim. (Q.)

Hab. Panama, Volcan de Chiriqui (Champion).—Cotoma1a (Mus. Brit., coll. Solari).

Three specimens of this species have been found in Chiriqui, and others from

Colombia are contained in various collections. The tubercles on the elytral interstices

vary in size and number, these being wholly absent in the variable P. depressifrons,

the latter also wanting the compressed prominence at the sutural angle. The

mandibles have a stout, conspicuous, truncated process in front in both species,

* Type probably lost.

POLYDACRYS. 219

3. Polydacrys mucronatus, sp. n. (Tab. IX. figg. 19, 19a, @.)

Oblong-obovate, piceous, the antennee (the club exccpted) ferruginous; sparsely clothed with very small

brown scales, the prothorax with a line of paler scales along each side of the disc, extending on to the

base of the third elytral interstice ; the upper surface also set with numerous stiff, blunt, suberect, light

and dark setee, which are uniseriately arranged down each elytral interstice, the legs strongly setose.

Head and rostrum comparatively narrow, densely punctate, together about as long as the prothorax, the

head feebly canaliculate, the groove extending forward to the v-shaped ridge on the rostrum, the nasal

plate smooth ; eyes convex, laterally prominent; joint 2 of the funiculus shorter than 1. Prothorax

nearly as long as broad, somewhat rounded at the sides, closely punctate and subgranulate. Elytra in the

@ inflated and at the middle nearly twice as wide as the prothorax, narrower and more oblong in the d,

with rows of closely placed, coarse, transverse punctures, separated by rather convex interstices, the

interstices each with a few smooth scattered granules, the suture mucronate at the tip in the 9.

Length 44-5, breadth 17-2 millim. (6 Q.)

Hab. Panama, Bugaba (Champion).

One pair. Closely related to P. sertegranosus, but with a relatively narrower head

and rostrum ; a smaller prothorax, with the sides more rounded ; the elytra mucronate

at the tip in the female, and with small scattered granules on the interstices; the

mandibles with a shorter and smaller truncated process in front.

4. Polydacrys nigrofasciatus, sp. n. (Tab. IX. fig. 20.)

Oblong, black or piceous, the antenne in great part ferruginous ; thickly clothed with cinereous and blackish

scales, the latter condensed into a median vitta (of variable width) on the prothorax (sometimes wholly

wanting) and three, oblique or curved, transverse patches on each elytron, these markings sometimes

confluent, or united into three common fascia, or partly obsolete; the upper surface also closeiy set with

short, stout, erect, blunt, pallid sete, which are uniseriately arranged down each elytral interstice, the

legs albo-setose. Head and rostrum densely punctate, together a little longer than the prothorax,

the rostrum finely canaliculate down the middie to the v-shaped ridge; eyes large, moderately

prominent ; joint 2 of the funiculus much shorter than 1. Prothorax broader than long, subcylindrical,

slightly constricted at the base, densely, finely punctate. Elytra much wider than the prothorax,

somewhat inflated posteriorly in the 2; with rows of closely placed, rather coarse punctures separated

by feebly convex, rugulose, faintly uniseriate-punctate interstices.

Length 33-42, breadth 13-14 millim. (¢ @.)

Hab. Mexico, Salina Cruz and Tehuantepec in Oaxaca (nab, in U.S. Nat. Mus.) ;

Numerous examples, mostly from Tehuantepec. Smaller than any of the varieties

of P. depressifrons, the eyes less prominent, the elytra closely set with short stiff sete.

The markings are very variable, according to the predominance of the cinereous or

blackish scales, the median vitta on the prothorax and the post-basal and subapical

patches on the elytra being obsolete in light-coloured examples (leaving only a

transverse curved mark just beyond the middle of each elytron), the darker individuals

having the elytral fascie longitudinally coalescent (leaving a few scattered cinereous

spots only) or transversely confluent. ‘The present species bears a superficial

resemblance to the apterous Mitostylus gracilis, Horn.

PREPODELLUS.

Prepodellus, Kirsch, Berl. ent. Zeitschr. 1867, p. 239.

This genus was based upon two small species from Colombia and a third is now

added from Central America. They have the head and rostrum narrow, the rostrum

subcylindrical, with an extremely short, inconspicuous nasal plate, and the scrobes

lateral, deep, and obliquely descending ; the eyes rather large, oval, and not prominent ;

the mentum small, not covering the maxille ; the mandibular scar small; the antenne

inserted near the apex of the rostrum, the scape reaching the front margin of the

prothorax ; the anterior coxe contiguous ; the femora clavate and unarmed ; ; the tarsal

claws free; the body winged, densely squamose and strongly setose. In general facies

these insects resemble small Polydrosé.

1. Prepodellus viridisquamis, sp.n. (‘'ab. IX. figg. 21, 21a, 2; 22, ¢.)

Oblong, piceous or ferruginous, the antenne (the black club excepted) in part or wholly, and the legs

entirely, ferruginous; densely clothed with small golden-green or pale greenish scales and also thickly

set with erect, stout, blunt, pallid sete, which are uniseriately arranged down each elytral interstice,

. the legs albo-setose. Head and rostrum densely, very finely punctate, the rostrum about as long as the

exposed portion of the head and slightly widened at the tip, the scrobes deep, strongly sinuate, and

partly visible from above (appearing subangulate); eyes large, oval. Prothorax subcylindrical, not so

long as broad, feebly constricted at the base and towards the apex, densely punctate. Elytra much

wider than the prothorax, moderately long, subparallel in g, slightly widened to the middle in 9;

finely punctate-striate, the interstices flat, densely, minutely punctate. Penis-sheath of ¢ (fig. 22)

strongly acuminate at the tip.

PREPODELLUS.—CYPHINA. 221

Found in numbers at Pefia Blanca, these specimens (somewhat immature) having the

antenne ferruginous, the club excepted. Very like P. nigriclava, Kirsch (the type of

which, as well as that of P. ruficornis, has been communicated by Dr. Heller for

comparison), but with the antenne inserted a little nearer the tip of the rostrum,

the scrobes more sinuate and partly visible from above, the elytral setze much shorter.

P. ruficornis has a longer rostrum, the prothorax rounded at the sides, and the elytra

maculate.

Group CYPHINA.

Under this group are placed the various genera with a broad, subquadrate or

oblong-subquadrate, flattened, narrowly sulcate rostrum; the scrobes lateral, sinuate,

and descending; the eyes convex and strictly lateral (thus being always separated above

by the full width of the rostrum); the scutellum minute or depressed; the humeri

prominent; the tarsal claws free; and the body winged. The eyes are often so

prominent that they might almost be described as subpedunculate. ‘The rostral

groove terminates at the base of the subapical plate (never extending across it, as in

Artipus, &c.), and the apical emargination is sometimes so deep that no definite bare

nasal plate is visible. ‘The outer strie of the elytra are coalescent or approximate

posteriorly in Cyphus, &c., and free in other genera, and the posterior tibiz may have

open or closed corbels, according to the development of the apical portion of the tibia.

The Cyphina, as defined above, include Cyphus, Germar, Hadropus, Mimographus,

Naupactus (the winged forms only), Plectrophorus, Apotomoderes, and Megalostylus,

Schonherr, Hoplopactus, Chevrolat (= Diaphorus, Faust), various new genera described

below, &c.; it is therefore not based on the characters used by Lacordaire or

Horn*. Pseudocyphus and Compsus approach Cyphus, but neither of these genera

has the eyes strictly lateral.

The Central-American genera of Cyphina may be tabulated thus :—

a. Antennal scape gradually or moderately clavate at the apex.

a’. Legs (the femora excepted) slender.

a’. Prothorax narrowly margined and feebly sinuate or truncate at the

base, short, subcylindrical, sometimes conical in 9.

prothorax ; antennw long and slender, the scape clavate at the tip and sometimes reaching beyond

the anterior margin of the prothorax, the second joint of the funiculus about twice as long as 1;

The numerous forms referred to this genus (which will include Mimographus rufipes,

suturalis, and griseus, Kirsch) may be briefly described as Hoplopacti* (represented

by such species as the Brazilian H. lateralis, Arrow) with unarmed anterior femora,

long, slender antenne, and an elongate second joint to the funiculus. The females of

some of the species, as in Mimographus, Hoplopactus, and Cyphus, have a more or less

10. Steirarrhinus cinereoguttatus, sp. n. (Tab. IX. fig. 34, 9.)

Q. Moderately elongate, piceous, the antenne ferruginous at the base; densely clothed (the legs included)

with cinereous and pale brown scales, intermixed with minute, scattered, hair-like scales, the cinereous

scales condensed into two sinuous vitte on the disc of the prothorax and various more or less coalescent

oblique spots and oblong streaks on the elytra; the scales on the lower surface uniformly cinereous.

Head and rostrum rather narrow, finely suleate from the v-shaped inter-antennal groove, the angular

anterior portion of the rostrum comparatively large. Antenne moderately long, slender, the scape

reaching beyond the eyes, joint 2 of the funiculus a little longer than 1, 3-7 becoming gradually

wider outwards, the club acuminate-ovate. Prothorax transverse, subcylindrical, narrowed anteriorly.

Scutellum small, triangular. Elytra broad, widening to the middle, bisinuate at the base, regularly

punctate-striate, the interstices feebly convex. Legs comparatively stout; anterior tibie sharply

unguiculate and obsoletely serrulate ; posterior tibie with a narrow, enclosed, sparsely squamose space

along the apical margin.

Length 84, breadth 33 millim.

Hab. CentRat America (Solari, ex coll. Jekel).

One specimen in very good condition *, kindly given to us by Signor A. Solari.

This species has a relatively shorter second joint to the funiculus and the angular

anterior portion of the rostrum longer than in the allied forms. The legs are so

densely squamose and setulose as to appear rather stouter than usual. The cinereous

spots on the median portion of the disc of the elytra are condensed into two short

oblique fascize. WS. cinereoguttatus has the elytra more sinuate at the base than in

S. nebulosus, and the head and rostrum narrower than in S. serripes and S. bicinctus.

11. Steirarrhinus cinctipennis, sp.n. (Tab. 1X. fig. 35, 2.)

Moderately elongate, piceous, the antenne ferruginous at the base; clothed above and beneath with rather

coarse brownish-cinereous scales, with minute, depressed, narrow, hair-like scales intermixed, the elytra

with an undulate fascia just beyond the middle and a spot on the outer part of the disc towards the

apex blackish-brown. Head and rostrum rugulosely punctate, feebly canaliculate to the sharply-

defined v-shaped inter-antennal groove, the nasal plate depressed, short, and triangular; antenne

moderately long, slender, the scape not reaching beyond the eyes, joint 2 of the funiculus more than

twice as long as 1, 3-7 obconic, subequal in length, becoming stouter outwards, the club stout and

acuminate. Prothorax small, transverse, rounded at the sides, obliquely narrowing anteriorly, broader

than the head with the eyes, rugulosely punctate. Scutellum small, triangular. Elytra broad,

moderately long, widening to the middle in @; rather coarsely punctate-striate, the punctures somewhat

transverse, the interstices feebly convex. Anterior tibie, and the intermediate tibia also in d,

unguiculate, the anterior pair without denticles. Third tarsal joint large.

Length 62-74, breadth 23-23 millim. (od 2.)

Hab. GuaTeMaua, Senahu in Alta Vera Paz (Champion).

One pair. ‘This species has rather short, broad, fusco-fasciate elytra, a small

prothorax, stout antennal club, &c.

MIMOGRAPHOPSIS, gen. nov.

Rostrum oblong-subquadrate, sulcate, flattened, emarginate at the apex, with a small, triangular or v-shaped,

bare nasal plate followed by a broad, arcuate, concave area, the scrobes deep, lateral, sinuous, extending

as far downwards as the lower limit of the eyes, the latter large, convex, strictly lateral; antennse

moderately slender, the scape clavate at the tip and reaching as far as or beyond the posterior margin

of the eyes, the joints of the funiculus obconic, 2 elongate, the club oblong, acuminate ; mentum

covering the maxille ; mandibles with a conspicuous prominence bearing the deciduous piece; prothorax

transverse ; scutellum minute or small, triangular; elytra 10-striate, much wider than the prothorax,

sinuate at the base, the humeri prominent, the outer stria becoming confluent towards the middle ; legs

rather slender; femora clavate, unarmed ; anterior tibie denticulate and unguiculate, bowed at the

apex; posterior tibie feebly or narrowly laminate at the apex, the glabrous articular surface ascending

and densely ciliate externally ; body oblong, rather slender, more or less squamose, winged.

Type, M. viridicans.

The two species referred to this genus are intermediate, as it were, between

Steirarrhinus and the insects here placed under Cyphus, differing from the former in

the confluent outer strie of the elytra and the more prominent humeri, and from

the latter in their relatively narrower head and prothorax and more slender build.

The laterally placed, convex eyes, shorter rostrum, smaller scutellum, &c., distinguish

Mimographopsis from Exophthalmus and its allies. M. viridicans is remarkable in

having the elytra nodose in the female. There are no visible impressed lines at the

base of the fifth ventral segment in this sex in either of the two species. The

scales are rounded, rather large, and imbricate in J. viridicans, and clustered into

smail spots in J/. pustulatus.

1. Mimographopsis viridicans, sp.n. (Tab. X. figg. 1, la, ¢; 2, 2a, 9.)

Oblong, narrow (3), broader (2), black; densely clothed (the legs included) with rather large, rounded,

imbricate, greenish, greenish-white, or cinereous scales, those around the eyes white, and also set with

extremely short, minute, scattered hairs, the whitish scales on the prothorax sometimes condensed into

two faint vitte on the disc, the widely separated seriate punctures on the elytra bare; the antenne (the

club excepted) finely pubescent and also with long bristly hairs, the club blackish-brown. Head and

rostrum finely punctate, narrowly sulcate to the u-shaped raised subapical plate, the scales on the latter

small; antennal scape not extending beyond the eyes, joint 2 of the funiculus nearly twice as long as L.

Prothorax much broader than long, slightly nurrowed and constricted in front, transversely wrinkled

towards the base, rugulosely punctate, the dise sometimes depressed or feebly sulcate down the middle.

Scutellum minute or scarcely visible. Elytra flattened on the dise anteriorly, with rows of widely

scattered, irregularly distributed, rather coarse, bare punctures ; the interstices densely punctate, 3 with

an oblong tuberculiform prominence at about one-third from the apex, and 5 sometimes slightly raised

at its point of termination, in Q, these prominences not or barely indicated in §. Ventral segments 3-5

with a line of erect pale brownish hairs down the middle, 5 broadly foveate at the apex, and 1 hollowed

down the centre, in g. Legs rather slender; anterior tibiz very finely and sparsely denticulate,

sharply unguiculate in ¢ , more feebly so in 2.

Var. The elytra with an elongate streak at the middle of the Sth interstice, and a shorter one on the 3rd

nearer the apex, black (fig. 2).

Length 8-104, breadth 23-4 millim. (¢d 2.)

Hab. Costa Rica, between Mata de Lefia and Rodeo, Pacific slope (Pittier: @ ),

Tuis (Lankester, in U.S. Nat. Mus.: 3), Azahar de Cartago (Underwood: ¢, var.) ;

Panama, Volcan de Chiriqui (Champion: 3 2).

Twelve specimens, three only of which are from Costa Rica, two of these latter

with the scales green and metallic, the others with the scales opaque and whiter.

The seriate punctures on the elytra vary in size. The penis-sheath of the male is

acuminate at the tip.

2. Mimographopsis pustulatus, sp.n. (‘Tab. X. figg. 3, ¢, 4, 2; 5, 2, var.)

Oblong, shining, black; above sparsely clothed with small, whitish, cinereous, or green scales intermixed with

minute pallid hair-like scales, the larger scales clustered into various scattered dense spots on the elytra

~ and two faint vitte: on the prothorax ; beneath somewhat densely squamose along the sides and sparsely

clothed with short, fine, adpressed hairs down the middle; the scales on the legs uniformly cinereous or

green with those on the knees blue. Head and rostrum finely punctate, sulcate down the middle, the

rostrum finely carinate on each side; antennal scape reaching beyond the eyes, joint 2 of the funiculus

much longer than 1. Prothorax transverse, narrowed in front, broadly depressed down the middle,

rugulosely punctate. Scutellum very small, subtriangular, vertical, squamose. Elytra moderately long,

subparallel in their basal half in g, broader and gradually widened to the middle in 2, produced and

conjointly rounded at the apex, with a common transverse excavation immediately below the base (the

basal margin to the 3rd row of punctures thus appearing raised); coarsely, closely seriate-punctate,

the interstices punctate and feebly convex, the spaces occupied by the patches of larger scales appearing

somewhat depressed. First ventral segment hollowed down the middle in g. Anterior tibie

unguiculate and feebly denticulate.

Var. The scales green, those on the head and prothorax condensed into two sharply defined vittz, and those

on the elytra into oblong subconfluent patches on the alternate interstices and an oval subapical spot ;

the rostrum depressed in the middle, with a shorter median sulcus and the lateral carina wanting; the

prothorax granulate ; the elytra transversely rugose at the base ( 9 ).

Hab. Costa Rica, Santa Clara (Siolley), Monte Retondo (Underwood), Turrialba,

Tucurrique (U.S. Nat. Mus.); Panama, Volcan de Chiriqui (Champion).

Eighteen specimens, all but four from Costa Rica, the latter including both green and

cinereous forms, the variety (fig. 5) being from ‘Tucurrique. ‘This species bears an extra-

ordinary resemblance to the Costa Rican and Panama insect described by Pascoe under

the name of Kustales stellaris* ; but may be distinguished from it at a glance by the

more slender antenne, the prominent, strictly lateral eyes, the sulcate (not carinate)

rostrum, the non-mucronate apices of the elytra, &c. From WM. viridicans it may be

separated by the more sparsely squamose upper surface—the scales on the elytra

clustered into spots or streaks (which sometimes tend to form oblique or curved series

across the disc) and the seriate punctures more numerous,—the non-tuberculate elytra

of the female, and the less acuminate apex of the penis-sheath in the male.

MIMOGRAPHUS.

Mimographus, Scliénherr, Mant. sec. Cure. p. 84 (1847); Kirsch, Berl. ent. Zeitschr. 1867,

p. 224 (part.).

This genus, as adopted here, includes the $.-American species referred to it by

Kirsch (the types of fifteen of which I have seen) with the elytra setose and their

outer stria coalescent or very narrowly separated from about the basal third; and the

antenne comparatively short, with the second joint of the funiculus at most a little

longer than the first, and the club acuminate-ovate. MW. amandus, Kirsch, is taken

as the type; IM. dentipes belongs to Hoplopactus, Chevr.; and three others are

provisionally referred to Stetrarrhinus *, ‘The single representative known to me from

within our limits is so closely related to the Colombian JZ. jekela that the Mexican

habitat seems doubtful.

Mimographus mexicanus, Jekel, in litt.

9. Oblong, shining, piceous; thickly clothed (the legs included) with small greenish-white scales, which

are condensed into a faint vitta on each side of the prothorax; the elytra with a series of minute

scattered bare spots along each interstice, and a common, transverse, sparsely squamose patch on the

disc below the base and a larger one beyond the middle, the latter limited behind by a sinuous, oblique,

sharply defined, bare space ; the upper surface also set with long, scattered, erect, stiff, pallid sete, and

the under surface, legs, and antenne with long hairs. Head and rostrum narrowly sulcate, densely

punctate ; antennz rather short, extending very little beyond the base of the prothorax, joint 2 of the

funiculus not much longer than 1, 3-7 short and moniliform, the club acuminate-ovate. Prothorax

transverse, slightly constricted before the apex, feebly bisinuate at the base; densely, rugulosely punctate,

obsoletely sulcate posteriorly. Scutellum depressed, very small. Klytra gradually widening to

the middle, sinuate at the base, with rows of closely placed rather coarse punctures, the tenth and

eleventh striz complete, the interstices somewhat convex on the disc, the position of the ‘sete indicated

by the minute bare spots. Fifth ventral segment with a faint oblique groove on each side at the base,

Anterior tibix finely denticulate, unguiculate at the inner apical angle.

Hab. Mexico (Mus. Lrit., ex coll. Jekel).

One specimen, in very good condition, acquired in 1868. Closely allied to the

Colombian M. jekeli, Kirsch (the unique type, 2, of which I have seen), but with

the antenne stouter and more closely setose, and the outer joints of the funiculus

transverse; the scales greenish-white throughout; the oblique bare space on each

elytron placed a little beyond (instead of at) the middle, and the setz less numerous.

Naupactus, Schdnherr, Gen. Cure. i. p. 567 (1833), vi. 1, p. 1; Lacordaire, Gen. Col. vi. p. 66

(part.).

The genus Waupactus is here restricted to the winged forms only (type Curculio

rivulosus, F.), Dr. Sharp having already (anted, p. 152) transferred the apterous ones to

Pantomorus (=Aramigus and Phacepholis, Horn). Schonherr included 140 species

in it, the winged representatives belonging to the Stirps IV. of his later work. The

essential characters of the three Central-American forms known to me are as follows :—

Rostrum broad, subquadrate, flattened, notched at the tip, the bare nasal plate extremely short, the scrobes

lateral, sinuous, and descending to beneath the eyes, the latter stiictly lateral, convex, and very prominent,

the head narrowly extended behind them; mentum small, transverse, almost filling the buccal cavity,

arising from a short peduncle ; mandibles with a large scar in front; antenne long and slender, joint 2

of the funiculus about twice as long as1, the scape nearly or quite reaching the front of the prothorax ;

prothorax deeply sinuate and broadly margined (as seen from behind) at the base; scutellum small ;

elytra much wider than the prothorax, sinuate at the base, with rather prominent humeri, 10-striate,

the outer striz approximate from basal third ; femora clavate, unarmed, the anterior pair stout; anterior

tibia denticulate; posterior tibia with the apex laminate and squamose, the glabrous articular surface

cavernous and ascending ; tarsi with the basal joint rather long, the claws free; body winged, squamose,

in life clothed with a powdery exudation.

N. cinerascens, Perroud, from Guatemala, is unknown to me, but it is apparently

winged and may be congeneric with the species from which the above characters

are taken. Two of these latter have a corresponding apterous Pantomorus in

Mexico. WN. sulfuratus was, in fact, sent us with Pantomorus stupidus from the same

locality, and both insects in life are similarly lineate with a sulphur-yellow powdery

exudation. This suggests a possibility that certain Pantomori may prove to be

dimorphic, the presence of wings being correlated with well-developed humeri, the

sinuation of the base of the prothorax and elytra, and a larger scutellum: if this

proves to be the case, N. sulfuratus would be the winged form of Pantomorus stupidus

and NV. virescens the winged form of Pantomorus uniformis.

1. Naupactus sulfuratus, sp.n. (Tab. X. figg. 7, ¢; 8, 2, var.)

Moderately elongate, narrow (¢), broad (@), nigro-piceous or black; the head on each side between the

eyes, the prothorax with two curved vitte on the disc and another on each flank, and the elytra with

a sinuous interrupted stripe on the disc (commencing and ending on the third interstice, and occupying

more than half the length of the fourth), a broader stripe on the flanks, and sometimes one or two lines

on the disc, densely clothed with small cinereous, and the rest of the upper surface more sparsely set

with darker, scales, the head, prothorax, and elytra also with a short, rough, decumbent setosity ; the

under surface (except along the middle of the abdomen) and legs cinereo-squamose and sparsely pilose.

,Head and rostrum closely, finely punctate and sharply sulcate ; joint 2 of the funiculus twice the length

of 1. Prothorax transverse, rounded at the sides, bisinuate at the base; densely, finely punctate and

obsoletely canaliculate. Elytra much wider than the prothorax, sinuate at the base, the humeri some-

what tumid; rather coarsely punctate-striate, the interstices feebly convex and densely punctulate.

Ten examples, those found by Mr. F. Knab in very fresh condition, and with the

prothorax and elytra beautifully lineate with a powdery sulphur-yellow exudation.

The three uniformly cinereous females are from the same localities, Acapulco and

Salina Cruz. The prothorax is more rounded at the sides than in the following

species. Perhaps a winged form of Pantomorus stupidus, Boh., an insect occurring

at the same places in Oaxaca. ‘The two specimens figured are from the same locality,

Acapulco.

2. Naupactus virescens, sp.n. (Tab. X. figg. 9, ¢; 10, 2, var.)

Moderately elongate, narrow (¢ ), broad ( @ ), nigro-piceous ; (¢ ) thickly clothed with green or bluish-green

scales, sometimes with cinereous scales intermixed, the prothorax with two narrowly separated vitte on

the disc and another on each side, and the elytra with the suture, a line down the interstices 5 and 7,

and a streak on 3 below the base, infuscate or more sparsely squamose, the surface also set with a short

rough, decumbent setosity; (@) uniformly clothed above and beneath with pale green scales. Head

and rostrum densely punctate and narrowly sulcate; joint 2 of the funiculus twice as long as 1.

Prothorax transverse, bisinuate at the base, somewhat conical in @, the sides parallel behind in ¢;

densely, finely punctate, obsoletely canaliculate at the base. Elytra a little wider than the prothorax,

feebly sinuate at the base; punctate-striate, the interstices almost flat and densely punctulate. First

Hab. Mexico (coll. Pascoe), Tehuantepec (Sailé).

Three males and one female, the former with more or less distinct dark stripes

on the prothorax and elytra, the latter uniformly clothed with green scales. ‘The

female corresponds with Pantomorus uniformis, of which the present species may

prove to be a winged form. The male has the sides of the prothorax less rounded,

and the female the elytra less sinuate at the base and relatively shorter, than in

N. sulfuratus.

Oblong, narrow (¢ ), broader (@ ), black or piceous, the elytra sometimes brown; the head and rostrum, the

prothorax with two curved vitts on the disc and another on each flank, the elytra with an interrupted

stripe on the disc (formed by three confluent streaks—the first oblong, the second triangular and oblique,

the third elongate), the fifth interstice in part, and a strongly sinuate band on the flank, the legs, and

under surface, thickly clothed with small cinereous or whitish scales, the rest of the upper surface set

I have seen twelve specimens of this species; two of those in the British Museum,

received in 1855, are labelled “ Guatemala,” but no reliance can be placed on this

locality. The insect when fresh is thickly clothed with an ochreous or sulphur-yellow

exudation, through which the markings are traceable. The short, broad head and the

still more prominent eyes separate the southern JV. laticeps from its Mexican allies.

This insect is stated to be near N. cinerosus, Schonh., but to differ in its larger size,

and in having the prothorax broader than long and bisinuate at the base, the elytra

each extending forward at the base, &c. It is 11 mm. long, including the rostrum;

uniformly clothed with cinereous scales, and also pubescent; the elytral inter-

stices 4-7 gibbous towards the apex. This lJast-mentioned character differentiates

NV. cinerascens from any of the species in our collection.

GERMARIELLA, gen. nov.

Rostrum broad, flattened, subquadrate, the upper portion widened towards the base, sulcate, emarginate at

the apex, the bare nasal plate extremely short, the scrobes deep, sinuous, extending to beneath the eyes,

the latter rounded, convex, and strictly lateral; antenne slender, the scape feebly clavate and about

reaching the posterior margin of the eye, Joint 2 of the funiculus much longer than 1. 3-7 obconic;

prothorax short, rounded at the sides, broadly margined (as seen from behind) and strongly bisinuate at

the base; scutellum small, depressed; elytra very broad, comparatively short, sinuate at the base,

conjointly rounded at the apex, 10-striate, the outer strie approximate from the basal third; legs

slender, comparatively short ; anterior tibiz feebly denticulate and unguiculate ; posterior tibiee narrowly

laminate and squamose at the apex, the glabrous articular surface cavernous and ascending; tarsal

claws free; body oblong, winged, uniformly squamose, in life clothed with a powdery exudation.

Curculio juvencus, Oliv., and the very closely allied Cyphus pudens, Boh., seem to

me to be best separated from Cyphus, from which they differ in several details of

the elytra strongly lobed in front, with the humeri angular, and the seriate punctures

somewhat conspicuous; and the anterior tibie feebly unguiculate*. The entire

surface is uniformly clothed with cinereous scales, which in fresh specimens are again

Schénherr included a variety of forms under Cyphus, and the type of his Stirps I.

(C. argillaceus, Germ. = gibber, Pallas) does not agree very well with the N.- and

Central-American species, which mostly belong to his Stirps Il. (type Curculio

16-punctatus, L.); C. guvencus and its allies are here placed under a separate genus,

and there are other southern forms that will probably have to be eliminated sooner or

later. The species from our region placed under Cyphus may be known by their

subquadrate, broad, sulcate rostrum; the very prominent, convex, laterally placed

eyes; the comparatively short scape and the short obconic outer joints of the

funiculus of the antenne ; the bisinuate, feebly margined base of the prothorax; the

fusion or approximation of the outer elytral striae from about one-third from the base ;

the prominent humeri; the minute or obsolete scutellum; the laminate, squamose

apex of the posterior tibiz, with the glabrous articular surface ascending ; and tre

broad tarsi, at least in the males. The females of all of them have an oblique

impressed line on each side of the fifth ventral segment in front.

We have five specimens of this conspicuous Tropical-American insect from Van

Patten’s Costa Rican collection, though this locality seems to require confirmation.

These examples agree with others before me from Oolombia and Venezuela. ‘They

are densely clothed with small green or pale blue scales; the prothorax and elytra

together with sixteen small, sharply-defined, black spots—two on each side of the

prothorax and six on each elytron, the one beneath the shoulder not visible from above

and thy one near the suture sometimes transversely arcuate ; the intermediate and

posterior femora spotted with black. The elytra have laterally projecting, angular

humeri, and the sutural region gibbous at the commencement of the apical declivity,

characters separating C. 16-pwnctatus from its northern representative, C. modestus.

The anterior tibie, too, are distinctly unguiculate in the southern form, and almost

unarmed in C. modestus. South-American specimens sometimes have larger spots or

the subapical markings partly coufluent.

A common insect in Mexico and varying in colour of the vestiture—white,

cinereous, brownish, or olivaceous—and in the development of the black markings

on the prothorax and elytra. ‘The following forms may be noted :—

a. Prothorax with three arcuately-arranged spots on each side and a transverse one on the disc, the elytra

each with six spots (two below the shoulder, obliquely placed, one on the disc before the middle,

transverse, and three forming an interrupted, angulate, subapical fascia), and a common scutellar one.

Mr. Wickham informs us that he has taken this species in abundance at Rio Balsas,

freshly emerged, in the early part of August, upon various bushes on the face of the

mountain just across the river from the village. Amongst the eighty-two specimens

examined by me, two only belong to var. a, eighteen to var. B, and three to var. 0, the

true C. modestus (= var. y) being represented by a long series, and the var. viridans

(= var. «) by numerous examples, including three from the Sturm collection. The

male (of both C. modestus and C. viridans) has the penis-sheath broad and truncated at

the apex (figg. 13a, 0). The length varies from 12-20 mm. The types of Gylleuhal

and Boheman were examined some years ago by Dr. Sharp.

Oblong, robust, black, densely clothed (a small space behind each eye excepted) with pale green, bluish-green,

or greenish-cinereous scales, with minute, scattered, whitish, decumbent hairs intermixed ; the prothorax

with two small spots on each side (those at the base sometimes obsolete), the elytra each with six or

seven small spots (one above and one below the shoulder, one on the disc before the middle, and some-

times another in a line with it on the eighth interstice, and from 2-4—the inner ones sometimes

coalescent—at about one-third from the apex), and the intermediate and posterior femora each with a

single spot, black. Head and rostrum sharply suleate and densely punctate, the rostrum hollowed at the

campanulate in 9; densely, finely punctate, the disc transversely excavate in the middle posteriorly

and with an abbreviated median sulcus. Elytra finely seriate-punctate, the ninth row of punctures sub-

obsolete for some distance before the middle, the interstices flat and densely punctulate, the apices

acuminate and dehiscent. Fifth ventral segment with an oblique impressed line on each side in front

the punctures of the strize somewhat scattered and not covered by the vestiture, the

prothorax with two small, obliquely placed, black spots on each side posteriorly, the

head (as in C. modestus) with a small bare spot behind the eyes. C. placidus, Horn,

also from Arizona, must be a very closely allied form, perhaps not really distinct from

C. lautus.

TETRAGONOMYUS, gen. nov.

Rostrum broad, flattened, oblongo-quadrate, emarginate at the apex, with a large, triangular, depressed,

rugose, bare nasal plate, which extends backwards to between the points of insertion of the antennee and

is limited on each side by an oblique ridge, the scrobes lateral, sinuous, deep, running downward to

beneath the eyes, the latter convex, strictly lateral, very prominent ; antennal scape not extending beyond

the eyes, flattened, rapidly widened outwards, slender at the base, joint 2 of the funiculus much longer

than 1, 3-7 obconic, the club stout, acuminate-ovate; mentum large, covering the maxilla; mandibular

scar placed on the lower surface ; prothorax subcylindrical ; scutellum very small, triangular ; elytra broad,

oblongo-subquadrate, set with large tubercles, 10-striate, the outer strie contiguous from about the basal

third, the lower margin strongly sinuate; femora clavate, unarmed; anterior tibie dilated, strongly

bisinuate within, sharply unguiculate at the tip; posterior tibie narrowly laminate at the apex, the

glabrous articular surface ascending and denscly ciliate externally; tarsal claws free; body oblong,

winged, squamose, covered with an earthy exudation.

Type, 7. tuberosus.

Amongst the Tropical-American genera with a broad, subquadrate rostrum, and

laterally placed, very prominent eyes, Tetragonomus may be known by the large,

triangular, depressed, rugose nasal plate, the subcylindrical prothorax, the broad, sub-

quadrate, strongly tuberculate elytra, and the dilated, deeply sinuate anterior tibie.

The single species referred to this genus has the appearance of a subcortical insect,

and it may have been found under bark.

1. Tetragonomus tuberosus, sp.n. (Tab. X. figg. 21, 21 a.)

Oblong, black or piceous, the funiculus and tarsi reddish ; coated with a dull brown earthy-looking exudation,

which partly hides the small, closely placed, reddish-brown scales, the elytral tubercles with a few setiform

scales, the legs strongly setose, the setee becoming more crowded on the anterior tibiee. Head and rostrum

densely, rugulosely punctate, finely sulcate to the nasal plate, the rostrum parallel-sided and a little longer

than broad. Prothorax transverse, slightly narrowed in front, bisinuate at the base, the hind angles

rather sharp and extending backwards ; transversely wrinkled and irregularly punctate. Elytra nearly

twice as broad as the prothorax, flattened and subparallel to beyond the middle, and then abruptly

declivous and obliquely narrowing to the apex, deeply sinuate at the base, rather coarsely seriate-

punctate; each elytron with about ten large tubercles—one on the third interstice below the base,

one on the shoulder, two oblique series across the disc (the tubercle on 3 at about one-third from the

apex very large), and two placed transversely near the apex. Intermediate tibie with a rather long

uncus in ¢.

MEGALOSTYLUS.

Megalostylus, Schénherr, Gen. Cure. vi. 1, p. 114 (1840); Lacordaire, Gen. Col. vi. p. 111.

Megalostylus agrees with Cyphus in having the posterior tibiz laminate and squamose

at the apex, and their articular surface ascending, and the rostrum deeply, triangularly

emarginate at the tip (so that there is no definite bare nasal plate) and sides; the

outer strie of the elytra are entire; and the scape of the antennee of the male is very

stout, as in Platyomus. It is related to the Antillean Apotomoderes, which has toothed,

strongly clavate anterior femora and the corbels of the posterior tibize small and open,

and to the new genus described below, in which the intermediate and posterior femora

are so deeply excavate near the apex as to appear toothed. ‘The species, so far as at

present known, are all confined to Mexico*, ‘They are extremely variable in size and

in the colour of the scales (there being both green and cinereous forms f in at least

three species); and the prothorax sometimes differs in shape in the two sexes, as in

certain Steirarrhinus. The males may be known by their longer and stouter antennal

scape, the broader third tarsal joint, the unguiculate apex of the intermediate tibie,

and the more or less hollowed first ventral segment; the females are broader, and

often have the prothorax less sinuate at the base and the hind angles more extended

outwards than in the males. The anterior tibie are toothed at the outer apical angle

in both sexes. The smallest specimens seen, as in Megalostylodes, are females.

Unfortunately, nothing has been recorded of the habits of these insects,

This species may be known by its not very densely squamose surface; the red legs;

the conical prothorax, with the base feebly sinuate, and the hind angles acutely

extending outwards in both sexes; the rather large scutellum ; the posteriorly setose

suture of the elytra, the elytra themselves broader than the prothorax, and somewhat

depressed in the female; and the hairy under surface and legs. ‘The scales on the

upper surface vary in colour—greenish, bluish, olivaceous, or cinereous, those on

the scutellum and the sides of the body beneath whitish. ‘The first ventral segment

is hollowed down the middle in the male. J/. rhodopus is apparently a common

with the scape of the antenne slender at the base (and therefore strongly clavate),

the elytra considerably wider than the prothorax and with a series of short, fine,

The typical form of this species, sent us in abundance from Cuernavaca, is uniformly

cinereous or whitish, the variety with the scales green (not previously recorded) being

apparently much scarcer. Both forms have been received from Chilpancingo and

Amula. The prothorax is as wide at the base as the elytra in both sexes. The

rostrum is broadly excavate from the tip to near the eyes. The longitudinal plica

on the fifth ventral segment of the female is conspicuous. About sixty specimens

have been examined, the females showing considerable variation in the lateral

development of the hind angles of the prothorax. Lacordaire! gave no locality for

his A. albicans, and that given for it by Chevrolat 2—California—must be due to some

much smaller and less elongate than the equally variable J. albicans, the prothorax

is usually more sinuate at the base, the elytra in the female (and often in the male

also) are considerably wider than the dilated basal portion of the prothorax, and the

fifth ventral segment wants the longitudinal plicain that sex. In one or two examples

the elytra have a series of minute hairs along each interstice. Both metallic and

cinereous forms have been received from Cuernavaca and Cholula. One of the green

examples from Chilpancingo ( 2 ) measures 3745 mm. onlyinlength. Four rather large

females, without definite Mexican locality, have the hind angles of the prothorax

extending outwards and the base feebly bisinuate, and the vestiture cinereous mottled

with brown; they may belong to a different species.

7. Megalostylus fusiformis, sp.n. (Tab. X. fig. 32, 3.)

3. Oblong, fusiform, black, densely clothed with subopaque green or golden-green scales, and also set with

short, fine, semierect, pallid hairs. Rostrum slightly widened towards the base, broadly excavate

anteriorly, the median groove long; antennal scape much thickened outwards, reaching beyond the

eyes, the latter rounded and very prominent. Prothorax broad, transverse, conical, the sides slightly

rounded anteriorly, the hind angles acutely extending outwards, the base rather strongly bisinuate.

Scutellum very small. Elytra with the sides at the base forming an almost continuous outline with

those of the prothorax, gradually narrowing from the humeri, finely punctate-striate, the interstices flat.

First ventral segment hollowed down the middle, the fifth somewhat tumid along the median line.

Length 71-74, breadth 23-23 millim.

Hab. Mexico, Rio Balsas, near Cuernavaca (Wickham).

Two males, found in 1909. This insect approaches the green forms of JZ. albicans

and M. splendidus, but differs from them in the fusiform outline of the body, and the

largely developed prothorax, with rather strongly bisinuate base and the sides slightly

rounded anteriorly. The general shape is very suggestive of that of certain Hpitragi

(fam. Tenebrionide) of the same region.

3. Oblong, black, densely clothed above and beneath with whitish scales, the head, under surface, and

legs also more or less pilose, the antennal club blackish. Rostrum widened towards the base, broadly

excavate anteriorly ; eyes rounded, very prominent; antennal scape reaching the front of the prothorax,

stout, rapidly widening ontwards, joints 1-3 of the funiculus subequal in length, the other joints

shorter. Prothorax abruptly, quadrangularly explanate on each side from about the middle to the base,

and here much wider than the elytra and nearly twice as broad as long, the base moderately bisinuate.

Scutellum transverse. Elytra moderately long, gradually narrowing from the base, very finely

punctate-striate, the seriate punctures on the disc scarcely coarser than those of the flattened interstices.

First ventral segment hollowed down the middle, the fifth slightly tumid along the median line

posteriorly.

Length 8, breadth of prothorax 3, of elytra 24 millim.

Hab. Mexico, Rio Balsas, near Cuernavaca (LI. F. Wickham).

One specimen only of this remarkable species has been sent us by Mr. Wickham.

It was found in the summer of 1909. The broadly quadrangularly explanate

prothorax separates it at once from all the allied forms. It is possible that the

female may differ in this respect.

9. Megalostylus macrophthalmus, sp.n. (Tab. X. fig. 34, @ .)

9. Comparatively short, black, the legs obscure ferruginous; above clothed with bluish-grey, and beneath

with whitish, scales, and also set with pallid bristly hairs, those on the elytra long, erect, and

uniseriately arranged down each interstice. Rostrum transverse, broadly hollowed anteriorly ; antennal

scape barely reaching the posterior margin of the eyes, the latter oval and not very prominent.

Prothorax transverse, conical, feebly bisinuate at the base, the hind angles acute. Scutellum transverse

small, Elytra subparallel in their basal half, wider than the prothorax at the base, rather short, finely

punctate-striate, the interstices flat.

Length 43, breadth 2 millim.

Hab. Mexico, Jalapa (H6ge).

One specimen, somewhat abraded. Differs from the females of all the other

members of the genus in the oblong, somewhat depressed eyes; the elytra are

comparatively short and setose; and the legs are ferruginous, as in MV. rhodopus.

MEGALOSTYLODES, gen. nov.

Femora clavate, the intermediate and posterior pairs deeply excavate near the apex beneath, so as to appear

subangularly dilated; anterior tibia unarmed at the outer apical angle; head comparatively small ;

rostrum subquadrangular ; eyes convex, prominent, lateral; prothorax much narrower than the elytra

in both sexes; body hirsute and sparsely squamose above; the other characters as in Megalostylus.

Type, M. hirsutus.

‘The single species referred to this genus must be separated from Megalostylus

e e :

owing to its less developed head and prothorax, the subdentate, stout posterior femora

(especially noticeable in the male), the unarmed outer apical angle of the anterior

tibia, and the hirsute, sparsely squamose upper surface of the body. It appears to be

not uncommon in the Mexican State of Oaxaca.

Exophthalmini (Evotini), Horn.

The genera referred to this group have the scrobes lateral, long, and descending

(only in part visible from above); the eyes not strictly lateral; the vibrissee wanting ;

the scutellum distinct ; the elytra with or without supplementary striz, the outer striae

free (except in Mazenes); the metathoracic episterna widened in front ; the anterior

tibia unguiculate ; the posterior tibiz laminate at the apex (corbels closed) and with

the articular surface more or less cavernous; the tarsal claws free; and the body winged

pleurus). ‘The Exophthalmina include a large number of conspicuous South American

and Antillean forms, and the three genera referred to it by Horn—Lachnopus, Omileus,

and Evotus. Exophthalmus is represented by many species within our limits, but

some of the other Tropical American genera are wanting, e. g. Prepodes, Lachnopus,

Rhinospathe, Chevrolat, Bull. Soc. Ent. Fr. 1878, p. xix.

This genus includes two elongate, robust, subfusiform, winged, polished, black

insects nearly related to Exophthalmus. They have the rostrum broad, widened

anteriorly, bicarinate above, and also with a transverse inter-antennal ridge, the scrobes

obliquely descending, the antenne inserted near the apex; the eyes large; the

scutellum transverse; the elytra with two abbreviated supplementary strie towards

the apex externally, the outer strie entire, the humeri (in the type) obtuse in 2 and

dentiform in front in ¢, the apical declivity densely villose or squamose; the tibize

more or less sulcate externally, the posterior pair with the glabrous articular surface

large and cavernous ; the tarsi broad.

Pirris (Biolley), Escazu, Pozo Azul (Underwood), Irazu (Rogers), Piedras Negras

(U.S. Nat. Mus.) ; Panama, Chiriqui (Zrétsch, ex Staudinger).

A common insect in Costa Rica; the variety is represented by five specimens (¢ @ )

from Chiriqui. The squamose portions of the surface are usually more or less coated

with a powdery ochreous exudation, this being particularly noticeable on the excavate

scutellar patch. Chevrolat’s reference! to Hypsonotus albomarginatus, Motsch. (Etudes

Ent. v. p. 22), is incorrect.

2. Rhinospathe v-album, sp. n. (Tab. XI. figg. 2, 2a, 2.)

©. Elongate, robust, subfusiform, shining, black or piceous; almost glabrous above, except on the apical

declivity of the elytra, which is clothed with black or blackish-brown scales intermixed with semierect

black and white seta, the dark scales preceded by a common, v-shaped, irregular fascia of white scales,

the lower margin of the elytra and the sides of the body beneath also more or less albo-squamose, the

rest of the under surface with a few widely scattered adpressed hairs, the tibie and antenne setose.

Head and rostrum closely punctate; the rostrum longer than broad, widened outwards, obsoletely

carinate down the middle, and with a fine oblique carina on each side extending from the transverse

inter-antennal ridge to near the small inter-ocular fovea, the declivous apical portion hollowed, the sides

deeply foveate before the eyes, the latter large, rounded, and moderately prominent; antennal scape

widened from near the base. Prothorax about as long as broad, subeylindrical, gradually narrowing

from the middle forwards ; transversely wrinkled and very sparsely punctate, depressed and longitudinally

suleate in the middle at the base. Scutellum transverse, small. Elytra widened to the middle,

conically produced at the apex, excavate along the suture at the base; seriate-punctate, the interstices

flat or transversely wrinkled. Tibize denticulate within, the anterior pair feebly unguiculate.

Length 14-20, breadth 42-68 millim.

Hab, Guatemata (ea Donckier), Zapote (Champion), Escuintla (Conradt).

Four specimens. This species differs from FR. albomarginata in having the rostrum

less excavate behind the transverse inter-antennal ridge, and the declivous apical

portion less dilated ; the elytra neither depressed along the suture nor densely villose

at the apex, the basal excavation small and almost bare, the squamose apical portion

of their surface preceded by a common v-shaped fascia of white scales.

EXOPHTHALMUS.

Exophthalmus, Schénherr, Cure. Disp. Meth. p. 115 (1826) ; Gen. Cure. ul. p. 4; Lacordaire, Gen.

Col. vi. p. 120 (part.). .

The numerous species referred to this Tropical-American genus agree with the type

(Curculio quadrivittatus, Oliv.) in having two or more abbreviated supplementary rows

of punctures on the exterior portion of the disc of the elytra; the outer striz entire ;

the gene emarginate in front; the scrobes lateral, long, and descending; the eyes

large, more or less prominent, not strictly lateral; the vibrisse wanting; the scutellum

well developed; the femora unarmed; the tibiz with or without denticles, the anterior

pair unguiculate; and the body winged. Diaprepes* (type Curculio spengleri, L.)

and Prepodes (type Curculio vittatus, L.) are sunk by Lacordaire as synonyms of

Exophthalmus, but the former has well-developed vibrissee and the latter a conical,

flattened prothorax, regularly 12-striate elytra, &c.; Hustales (type Curculio thunbergi,

Dalm.) has a densely squamose triangular nasal plate, regularly 10-striate elytra, and

strongly bowed, stout anterior tibia. Amongst the species now added to Exophthalmus

—the type of which has a somewhat strongly exserted head and the base of the elytra

lobate,—one (L. sulcicrus) has grooved tibie ; but as this insect is closely related to

E. jekelianus, &c., it can remain in the same genus for the present. ‘The humeri

are prominent in both sexes of EL. verecundus, interpositus, and roralis, obtuse in

E. nicaraguensis, nubilus, lunaris, &c., and more prominent in the male than in the

female of E. agrestis. ‘The sexes of the last-mentioned insect are so dissimilar that

they have been described as separate species. All these forms, when fresh, are more

or less coated (especially on the depressed portions of the upper surface) with an

ochreous or yellow powdery exudation, which disguises the true colour of the

scales and often hides the sculpture also; the scales, moreover, in some of the species

(as in Megalostylus, &c.) vary in colour from metallic green to cinereous or white.

This fine species, the type (2) of which I have seen, approaches the Antillean

LE, quadrivittatus, Oliv., the type of the genus; but it has the head shorter and the

elytra less lobed at the base, the depressed dense patches of ochreous or whitish scales

on the latter arranged into interrupted arcuate or angulate fascie and a common

transverse scutellar spot. The scape of the antenne is widened from near the base

and setose; the rostrum has a broad smooth space down the middle; the prothorax is

feebly canaliculate and transversely depressed at the base, bivittate, the bare portion

in some specimens coarsely punctate and in others almost smooth; the seriate

punctures on the bare portions of the elytra are coarse and deep ; the small scattered

scales on the legs, apex of elytra, and rostrum are usually green or blue; the tibia

Apparently a common insect in the States of Vera Cruz and Oaxaca, It is easily

known from its allies by the transversely depressed inter-ocular portion of the head ;

the prominent eyes; the long second joint to the funiculus; the basally truncate,

closely punctured prothorax; the oblong, subtriangular, finely punctate-striate elytra,

with rather convex interstices and prominent humeri; and the feebly unguiculate

anterior tibie. The scales are uniformly coloured, usually pale green, sometimes bluish-

or golden-green, rarely whitish or cinereous. In several exaniples the alternate elytral

Platyomus (Compsus) carinirostris, Boh. in Schénh, Gen. Cure. vi. 1, p. 1877.

Var. The alternate elytral interstices not or very slightly raised, the humeri with a few opalescent scales,

similar to those on the legs and head.

Length 11-15}, breadth 3,%,-6,!, millim. (¢ 9.)

Hab. Mexico (Mus. Brit.), Toxpam, San Andres Tuxtla, Juquila (Sal/é), Cordova,

Oaxaca! (Hoge), Amula (H. H. Smith); Guaremata (coll. Pascoe), Coban (Champion) ;

Nicaragua, Chontales (Janson).

Not rare in the Mexican States of Oaxaca and Vera Cruz; the type is from the

first-mentioned State. The general vestiture is whitish or pearly-white, sometimes

greenish with the raised alternate elytral interstices and two vitte on the disc of the

prothorax white, the head, rostrum, prothorax, and legs often tinged with cupreous or

golden. ‘The sharply carinate rostrum, with the upper anterior portion Jess divergent

on each side in front, the more numerous elytral strie, &c., readily distinguish this

species from Compsus auricephalus. The antennal scape is slender at the base in the

female. The elytra have the alternate interstices 2, 4,6, 8, and the basal portion of 8,

widened and subcostate, and 8 bifurcate beyond the middle, the intervening space

enclosing two short supplementary strie. The two examples ( ? ) from Guatemala have

the elytral interstices uniformly flattened or the third very slightly raised anteriorly ;

they are very like /. margaritaceus, which has an obsoletely carinate rostrum and less

prominent eyes. ‘The specimen figured on our Plate has been compared with the

type in the Sommer collection, kindly lent by Mr. O. E. Janson.

7. Exophthalmus margaritaceus, sp.n. (Tab. XI. fig. 9, 3.)

Oblong, black, densely squamose, the scales on the prothorax, scutellum, elytra, and part of the under surface

bluish-white, those on the head, rostrum, legs, and last three ventral segments cupreous or opalescent ;

the surface also set with short, scattered, minute, adpressed hairs. Head and rostrum rugulosely

punctate, the rostrum considerably longer than the head and with a smooth median line, followed by an

oblong, narrow, inter-ocular fovea, the nasal plate short ; eyes very large, moderately convex; antenn

rather slender, the scape extending to just beyond the eyes. Prothorax strongly transverse, feebly

bisinuate at the base, arcuately narrowing from the middle forwards, faintly canaliculate; with scattered

irregular foveiform punctures intermixed with a fine interstitial punctuation. Scutellum rather large.

Elytra elongate-triangular, the apices divergent and mucronate, the humeri prominent; with rows of

small conspicuous punctures placed in shallow foveze, the two supplementary strie placed between

5 and 6, the interstices feebly convex. Anterior tibiz strongly, and the intermediate pair feebly,

unguiculate.

Length 12-13, breadth 4-4} millim. (<¢.)

Hab, Nicaragua, Chontales (Lelt).

Two specimens. This species approaches /. opulentus, but it has more prominent

humeri, the seriate punctures on the elytra conspicuous, and the vestiture uniformly

bluish-white above, except on the head, where it is cupreous. ‘The obsoletely carinate

rostrum and the less convex eyes separate /. margaritaceus from the variety of

E. carinirostris with flattened elytral interstices.

8. Exophthalmus albidus, sp.n. (Tab. XI. figg. 10, 10a, ¢.)

Diaprepes albidus, Sturm, in litt.

Oblong, black, densely clothed with chalky-white scales, and also set with short, scattered, minute, adpressed

hairs. Rostrum longer than the head, flattened above, shallowly sulcate on each side and subcarinate

down the middle, the carina followed by a short inter-ocular groove and extending forward to the long,

shining, triangular subapical plate; eyes large, rounded, convex; antennal scape extending to a little

beyond the eyes. Prothorax nearly as long as broad (along the median line), narrowed anteriorly, feebly

bisinuate at the base, slightly depressed down the middle, with scattered foveiform impressions intermixed

with the fine interstitial punctures covered by the vestiture. Scutellum rather large. Elytra elongate-

triangular, the apices divergent, the humeri prominent ; with rows of conspicuous punctures, the two

supplementary strize placed between 7 and 8, the interstices almost flat. Anterior and intermediate

tibie feebly unguiculate.

Length 143, breadth 53 millim. (¢.)

Hab. Mexico (Sallé, ex coll. Sturm).

One specimen. Very near the Nicaraguan LL. margaritaceus, but differing from it

in the slightly smaller and more prominent eyes, the longer glabrous subapical portion

of the rostrum, the less transverse prothorax, the position of the supplementary strie,

and the uniform chalky-white vestiture. Diaprepes is here restricted to forms having

well-developed vibrisse.

Var. The scales uniformly green or bluish-green.

Hab. Mexico, Tapachula in Chiapas (Hége); GUaTEMALA, El Tumbador, Las

Mercedes, El Reposo (Champion).

This species has a smooth, slightly raised median line on the rostrum; an incomplete

impressed line on the prothorax (often obsolete or hidden by the vestiture), the

prothorax itself sparsely, irregularly, foveato-punctate; the elytra separately rounded

at the base, with the seriate punctures moderately coarse, somewhat crowded, and each

placed in a shallow fovea. ZZ. opulentus (the type of which we have seen) is acommon

insect on the Atlantic slope of Vera Cruz and Tabasco; the variety has been found in

some numbers in Guatemala, as well as at Tapachula, on the Pacific slope. The

cupreous humeral spot is evanescent and often obsolete. Fresh specimens are some-

times coated with a brownish exudation.

10. Exophthalmus vitticollis, sp. n. (Tab. XI. figg. 12, ¢; 13 9,14 ¢,

vars.)

Eustales vitticollis, Chevr. in litt.

Very like Z. opulentus ; the head, rostrum, scape, legs, a median vitta on the prothorax, the scutellum, and

sometimes the elytral suture and a humeral spot also, clothed with cupreous or golden-cupreous scales,

the other scales green or golden-green ; the prothorax distinctly impressed along the median line; the

elytra transversely flattened or depressed at the base, the seriate punctures usually more conspicuous,

less approximate, and placed in larger fover. (Fig. 12.)

Var. a, cerulescens, n. The scales on the head, rostrum, humeri, and legs golden-cupreous, those on the

prothorax, scutellum, and elytra blue, and those on the apical half of the suture and under surface

green. (Fig. 13.)

Var. 8, mutatus,n. The prothorax with two broad stripes on the disc and another on the flanks, and the

elytra each with a broad stripe on the disc and another on the flank, clothed with brown or brownish

scales, the scales on the rest of the surface green, (Fig. 14.)

The typical form of this insect is common in the lower portions of the Polochic

Valley and it has long been known in collections under Chevrolat’s MS. name; the

var. a is represented by a single female from Temash River; and the var. 6 by five

males from Livingston, on the Atlantic coast. The median groove on the prothorax

is conspicuous and usually indicated by an irregular row of coarse punctures. The

smooth line along the rostrum is sometimes obsolete. |

11. Exophthalmus cupreipes, sp.n. (Tab. XI. fiz. 15, 2.)

Oblong, narrow (¢), broader and widened posteriorly ( 9 ), black ; densely squamose, the scales on the head,

rostrum, and legs, and along the middle of the prothorax anteriorly or to near the base, cupreous or

golden-cupreous, those on the rest of the surface green or golden-green, the elytral interstices also set

with short, scattered, adpressed setiform scales. Head and rostrum rugulosely punctate, the rostrum

longer than broad, sharply carinate, the carina extending forward to the v-shaped prominence limiting

the bare triangular nasal plate and followed by a narrow deep inter-ocular sulcus; antenne rather

slender, the scape reaching beyond the eyes, the latter large and moderately convex. Prothorax

transverse, arcuately narrowing forwards, feebly bisinuate at the base, hollowed down the middle

anteriorly and also canaliculate; with irregular, scattered foveee: intermixed with fine punctures.

Elytra with twelve rows of moderately coarse punctures, the interstices equal and feebly convex, the

apices feebly mucronate, somewhat acuminate in 9, the humeri moderately prominent.

Ten specimens, scarcely varying in colour, and probably all from the State of Oaxaca.

Easily separable from E. opulentus and E. vitticollis by the sharply carinate rostrum

and the v-shaped prominence limiting the bare nasal plate; the prothorax, too, is also

more or less hollowed down the middle anteriorly, as well as being finely canaliculate.

12. Exophthalmus carneipes, sp.n. (Tab. XI. figg. 16, 16a, ¢.)

Oblong, narrow (<), broader (@), black or piceous; densely squamose, the scales on the head, rostrum,

Seven specimens. In this insect the very prominent median carina of the rostrum

is bifurcate behind and encloses the deep lanciform inter-ocular sulcus, a character

separating E. carneipes from its allies. ‘The general coloration of the vestiture is

their basal half in g, much broader and widened to the middle in 9, the dorsal striae sometimes

interrupted or sinuous in this sex. Rostrum finely carinate, the cariua followed by a narrow sulcus.

Eyes somewhat depressed in Q, a little more prominent in 3. Scales varying in colour from whitish

or cinereous (with cupreous reflections) to green, the elytra often with denser patches on the disc and the

prothorax with a faint submarginal denser stripe on each side, the vestiture frequently covered in part

or disguised by a yellowish powdery exudation; the head, rostrum, and legs sometimes cupreous.

Anterior tibisee unguiculate.

Rafael Jicaltepec (U.S. Nat. Mus.), Jalapa (Hoge, Smith), Teapa (Hoge, H. H. Smith).

The types of the four species described by Boheman and Gyllenhal have been

examined by Dr. Sharp or myself, and there can be little or no doubt that they all

belong to one variable insect, for which the most appropriate name would be farino-

lentus: G. agrestis was based upon a single example (2 ) completely encrusted with dirt,

LL. canus and P. canescens upon poor specimens ( ¢ ), and P. farinolentus upon an

individual (2 ) with the characteristic vestiture intact. About 100 examples are now

available for comparison (including long series from Teapa, Cordova, Jalapa, Toxpam,

&c.), and these show great variation in the colour of the scales; the metallic green

variety, with cupreous rostrum and legs, is from Santacomapan in Vera Cruz, and the

other green specimens are from Teapa or Chiapas. The foveiform or bare depressions

on the third and fifth elytral interstices (unnoticed in Schénherr’s work, though clearly

visible in the dirty type of G. agrestis) are not accidental or due to abrasion, as they

are also to be found in Z. nubilus, E. distigma, &c. We figure four specimens: a

greenish male from Teapa (fig. 17); a female, agreeing with the type of P. farino-

lentus, from oxpam (fig. 18); a female of a greenish variety from Chiapas (fig. 19);

and a female of the var. a from Santacomapan (fig. 20).

14. Exophthalmus distigma, sp. n. (Tab. XI. fig. 21, ¢.)

Oblong, black; densely clothed with cinereous scales, which are usually cupreous, purplish, or greenish in

certain lights, and also set with small, scattered, adpressed setz, the vestiture sometimes more or less

hidden or disguised by a yellowish exudation. Head and rostrum rugulosely punctate, the rostrum a

little longer than broad and finely carinate to the rather long inter-ocular groove; eyes rounded,

moderately large, feebly convex ; antenne rather long and slender, the scape about reaching the anterior

margin of the prothorax, joint 2 of the funiculus slightly longer than 1. Prothorax transverse, obliquely

narrowed from the middle forwards, feebly bisinuate at the base, broadly depressed or flattened, and

sometimes obsoletely canaliculate, down the centre ; with a few, coarse, scattered punctures intermixed

with a close fine punctuation. Scutellum prominent, rather large. Elytra subparallel in their basal

half in ¢, broader and widened to the middle in @, feebly mucronate at the tip, the humeri rather

prominent ; with rows of scattered punctures placed in small foves, the interstices densely punctulate,

3 slightly raised to beyond the middle, and the space between it and the suture flattened or depressed,

5 with a more or less distinct, transverse, bare, almost smooth, foveiform depression at about the basal

third, and 4 sometimes with a similar depression beyond the middle, Anterior tibis strongly, and the

intermediate tibie more feebly, unguiculate in both sexes.

Length 77%,-124, breadth 24-5 millim. (¢ ¢ .)

Hab. Guaremaua, Cerro Zunil, Volcan de Atitlan, and Mirandilla, Pacific slope

Found in abundance at Cerro Zunil in August 1880. ‘This is the Guatemalan form

of the Mexican E. agrestis, from which it differs in having the elytra broadly flattened

or hollowed along the suture (the depression extending forwards on to the disc of the

prothorax), the seriate punctures more scattered, and the third interstice slightly raised.

‘The upper surface usually has a cuprecus or greenish lustre. The bare depression on

the fifth elytral interstice is constant.

15. Exophthalmus scalptus, sp.n. (Lab. XI. fig. 22, ¢-)

Oblong, narrow (¢), broader (Q ), black ; densely clothed (the head and rostrum more sparsely) with pearly-

white scales (which sometimes have a cupreous or greenish tinge), the prothorax and elytra with small,

scattered, bare—transverse, oblique, or foveiform—asymmetrically-arranged spots ; the surface also set

with minute, widely scattered, adpressed, setiform scales. Head and rostrum rather sparsely punctate,

the rostrum short, about as broad as long, hollowed on each side of the stout, arcuate median carina,

the latter followed by a small inter-ocular fovea, the eyes large and somewhat depressed; antenne

rather slender, the scape extending beyond the anterior margin of the prothorax. Prothorax transverse,

convex, rounded at the sides, feebly bisinuate at the base; the spaces between the scattered, bare,

irregular, foveiform depressions densely punctulate. Scutellum well developed. Elytra_ elongate-

triangular in d, broader and widened to the middle in @, separately mucronate at the tip, the humeri

not very prominent ; interruptedly seriate-punctate, the interstices (except in the places occupied by the

bare transverse marks) densely punctulate, 3 usually a little raised and the space between it and the

Fifteen examples. This species has the facies of a Compsus, but it is really related

to FE. impositus (Pasc.), having a similarly formed rostrum, &c. The irregular scattered

bare transverse scratches on the prothorax and elytra give the insect a peculiar

appearance; the eyes, too, are depressed, the rostrum short and arcuately carinate,

and the vestiture of the elytra is so dense as to make the seriate punctures appear

quite small.

Prepodes nubilus, Rosensch. in Schonh. Gen. Cure. vi. 1, p. 355°.

Naupactus aurivittis, Sturm, in litt.’.

Prothorax with a cupreous or coppery-white stripe on each side, and the elytra each with two similarly-

coloured stripes—one on the disc, sometimes evanescent or interrupted, the other along the lower

margin—the space between them bluish. Rostrum finely carinate to the inter-ocular fovea; eyes

moderately prominent ; prothorax hollowed down the middle and towards the sides, impressed with

coarse, scattered, irregularly distributed punctures; elytra narrowed towards the base in both sexes,

broad and widened to the middle in 2, narrower in ¢, the humeri not very prominent, punctate-

striate, the third interstice (beyond the middle) and the fifth interstice (at the basal third) irregularly

foveate, the depressions in some examples diverting the strie and in others smoother and bare; anterior

tibie feebly unguiculate ; body winged.

Hab. Mexico? (Sturm, in coll. Sallé; Mus. Brit.), between Acapulco and Oaxaca!,

I have seen seven specimens of this species (five of which belong to the Sommer

collection), one only of which bears a locality-label ‘“ Oaxaca.” The females have the

vestiture between the dorsal vitte of the elytra more or less cupreous, so that the

stripes are less distinct in this sex than in the males. The foveiform depressions on

the disc of the elytra (which are sometimes bare and almost smooth) are very similar

to those of E. agrestis and E. distigma.

Oblong, rather narrow (¢), broad (2), black; above densely clothed with yellowish-white scales, the

prothorax with three narrow vitte (the central one evanescent), and the elytra with a marginal stripe

of variable length (and in the ¢ the suture also), more sparsely set with smaller white or bluish-white

scales, similar to those on the under surface and legs; the dense vestiture more or less coated with

a powdery yellowish exudation ; the elytra with a transverse or oblique spot on the dise at about the

basal third, another within the shoulder, and three or four small spots beyond the middle, bare.

Rostrum longer than broad, flattened, rugulosely punctate, neither carinate nor sulcate; eyes large,

Oblong, shining, black; densely clothed (except along the middle of the head and rostrum, on two vitte on

the dise of the prothorax, on numerous irregular, confluent streaks or patches on the elytra, and along

a broad space down the middle of the metasternum and the ventral segments 1-4) with white or pale

brown scales—usually pale brown, with a broad stripe along the sides of the elytra and the legs white,—

and also set with minute widely scattered adpressed hairs. Rostrum about as long as broad, depressed

on each side of the smooth, stout, arcuate, median carina, which is widened behind and encloses the

inter-ocular fovea; eyes large, rounded, not very prominent; antenne long, the scape reaching the

anterior margin of the prothorax. Prothorax strongly transverse, narrowed in front, bisinuate at

the base, depressed or flattened down the middle, with scattered, irregular, foveiform punctures. Elytra

subparallel in their basal third in ¢, broader and widened to the middle in 9, mucronate at the tip, the

humeri prominent ; coarsely punctate-striate, the punctures appearing small where covered by the dense,

confluent, large patches of scales, the interstices flattened, the bare portions smooth. Anterior tibie

obsoletely denticulate and with a long terminal claw.

Hab. Nicaragua, Chontales! (Belt, Janson, Richardson) ; Costa Rica, Reventazon

I have seen about a dozen examples of this species, mostly females, varying very

little in the arrangement of the scales on the elytra. The prothorax is constantly

trivittate and the under surface bare down the middle. . impositus cannot possibly

be included in Eustales, the type of which 1s Curculio thunbergi, Dalm.

19. Exophthalmus triangulifer, sp.n. (Tab. XI. fig. 27, ¢ .)

Very like E. impositus; the scales more uniformly distributed above and beneath, brown or greyish-brown

(sometimes with a cupreous tint), intermixed with white, the white scales on the prothorax condensed into

a narrow sinuous stripe on each side and another on its flanks, and those on the elytra into an angulate

series of spots down the middle of the disc; the prothorax unimpressed along the median line; the

elytra with fewer bare spaces, one only (triangular or <-shaped) near the suture before the middle being

conspicuous, the scales clustered into smaller patches and giving a nodose or uneven appearance to the

flattened surface.

A common insect in Chiriqui. It is very closely related to E. impositus, both forms

occurring at Turrialba; but the uniformly squamose under surface, the non-sulcate

prothorax, and the different arrangement of the scales on the elytra readily distinguish

E. triangulifer.

20. Exophthalmus tessellatus, sp. n. (Tab. XI. fig. 28, 3.)

&. Elongate, subfusiform, shining, black; densely clothed with pale ochreous scales, except on the following

portions of the body—a line down the middle of the head and rostrum, a narrow vitta on the disc of

the prothorax and another on each flank, the scutellum, the suture, a submarginal stripe, the lower

margin, and various narrow transverse connecting lines on the elytra (leaving a series of eight large

subquadrate ochreous patches on the disc and another along the flanks), and a narrow stripe down the middle

of the body beneath,—which are sparsely ceeruleo-squamose, like the legs and tip of the rostrum; the surface

also set with minute scattered adpressed hairs. Head and rostrum closely punctate, almost smooth down

the middle, the rostrum much longer than broad and distinctly canaliculate, the inter-ocular fovea small ;

antenne rather slender, the scape reaching the posterior margin of the eyes, the latter rounded, large, and

prominent. Prothorax transverse, obliquely narrowed anteriorly, bisinuate at the base, narrowly suleate

down the middle; irregularly foveato-punctate, and with a fine interstitial punctuation, Scutellum large.

Elytra elongate-triangular, the apices each produced into a long tooth; the series of coarse punctures

(which appear minute where covered by the ochreous scales) interrupted by the raised transverse lines

connecting the sutural and submarginal partially denuded stripes. Anterior tibie strongly unguiculate.

narrowly separated, pale ochreous patches on the disc and flanks of the elytra, the

rest of their surface being sparsely ceeruleo-squamose, like the legs.

21. Exophthalmus albolineatus, sp.n. (Tab. XI. fig. 29, 9.)

Elongate, flattened above, black, the antenne (the club excepted) and tarsi piceous, the latter ferruginous at

the tip ; clothed with olivaceous and green scales above and green scales beneath, the elytra each with a

denser sinuous band of whitish scales running down the fourth or fifth interstice—this being broken up

into spots or streaks beyond the middle—and a short whitish stripe along the basal fourth of the lower

margin ; the surface also set with very short, scattered, decumbent hairs. Head and rostrum rugulosely

punctate, the rostrum longer than the head, flattened, and with an almost obsolete smooth median line,

followed by a small inter-ocular fovea; eyes somewhat depressed, moderately large, separated by the

full width of the upper portion of the rostrum; antenne rather slender, the scape reaching the posterior

margin of the eyes. Prothorax a little broader than long, cylindrical, narrowed in front, truncate at the

base, obsoletely canaliculate; densely, finely punctate. Scutellum rather large. Elytra elongate-

subtriangular, acuminate at the tip, the sutural angles divergent ; finely punctate-striate, the interstices

Hab. Mrxico, Cordova (Hoge).

One example, partly abraded above, the green scales distinctly clustered into patches

along the sides of the elytra beyond the middle. This insect has the general facies of

a Chlorophanus. ‘The eyes are widely separated (though not so strictly lateral as in

the Cyphina), the prothorax is truncate at the base and comparatively smooth, the

elytra are flattened above and have an interrupted whitish stripe on the disc. The

oblique lines on the fifth ventral segment are peculiar to the female, at least in the

Cyphina.

San Juan and Trece Aguas, the specimens with more extended markings coming from

Cubilguitz, &c. The immaculate variety is represented by five examples from British

Honduras, all the others being from Vera Paz. The gibbous, basally depressed elytra,

Brachyomus (type Curculio octotuberculatus, ¥.) or Synthlibonotus, from which it may

be separated by the long, lateral, obliquely descending scrobes, the free outer strie of

the elytra, the presence of supplementary striz on the disc of the latter, &c.

Mimographopsis pustulatus.

The type of P. jekelianus (labelled by White himself) is a female obtained from the

This is one of the commonest of the winged Otiorhynchids in the warmer parts of

Central America, from Guatemala southward, and it is unnecessary to enumerate the

precise localities where the insect has been captured. Five forms of it may be noted :—

a. The scales clustered into large confluent patches towards the sides of the elytra, and sometimes into one

or three vittz on the prothorax also (g @). [Fig. 12, ¢.] [jehelianus, White (part.).|—Guatemala to

Colombia.

f. The scales clustered into small patches over the whole of the elytral surface (2). [Fig. 18, 9 .]—Costa

Rica, Panama.

y. The scales clustered into one or three vitte on the prothorax, and a sutural, submarginal, and marginal

stripe on the elytra, the rest of the upper surface almost bare (¢ @). [Fig. 15, 9 .|—Guatemala to

Panama.

é. The scales clustered into a faint submarginal vitta on each side of the prothorax and an interrupted

submarginal stripe on the elytra(¢ 9). [Fig. 14, ¢.}/—-Guatemala to Panama.

e. The larger scales almost wholly replaced by minute, scattered, hair-like, pallid scales; the prothorax closely

granulate, the elytral interstices rugose, the swollen portion of the femora smooth, almost bare, and

usually rufous, the tibiz more deeply sulcate.—Costa Rica, Panama.

These varieties are connected by intermediate forms: y is represented by females

only, and e by a long series from Chiriqui, so that the specimens are probably not all

abraded. White did not observe the grooved tibie of the male of his P. yekelianus,

though he referred it somewhat doubtfully to the same species, the type of which is

correctly stated to be a female. ‘The tibial groove, it may be observed, is partly hidden

by the scales, and it therefore appears deeper in the less densely squamose varieties.

We figure four examples: a male of the typical form («) from Chontales; a female of

the var. B from Chiriqui; a male of the var. 6 from Costa Rica; and a female of the

var. y from Guatemala.

Mr. Janson has lent us the types of this insect (¢ 2) from the Sommer collection,

and I have seen about a dozen others, including a series from Juquila. The species

is scarcely recognizable from Boheman’s description. The mottled vestiture and erect

sete, the truncate base of the prothorax, the basally depressed, subcarinate rostrum,

and the prominent eyes are its chief characters. ‘The scales are metallic green on the

legs and under surface in the type (¢) (fig. 16) and some of the other examples |

CHAULIOPLEURUS, gen. nov.

Elytra with the flanks subangularly dilated or tumid below the humeri, the lower margin strongly sinuate,

the humeri somewhat prominent in the fully winged type, obtuse in the other species, the supplementary

strie present; rostrum widened anteriorly, uni- or tricarinate, the nasal plate triangular, bare, the

scrobes lateral, deep, and descending; eyes large, not prominent; antennal scape about reaching the

anterior margin of the prothorax ; scutellum small; tibise convex on their outer edge, the posterior pair

narrowly laminate and biciliate at the apex, denticulate along their outer half within (at least in 9 ), and

with the glabrous articular surface large; body polished and almost bare in the type, the depressions of

the prothorax and elytra squamose in C. guadrifoveatus ; wings fuliy developed or rudimentary.

Type, C. adipatus.

The three Costa Rican forms referred to this genus approach Exophthalmus jeke-

lianus and its allies, but are readily separable therefrom by the peculiar shape of their

elytra. They all have the meso- and metasternal side-pieces largely developed, as

usual in the winged forms. The three species, the type being only constantly winged,

differ greatly in general facies: C. adipatus has inflated, subglabrous, polished elytra

and the humeri prominent; C. rufovittatus is flattened on the disc and has rufo-vittate

elytra; C. quadrifoveatus has the disc of the prothorax and the base of the elytra (behind

the scutellum and on the outer part of the disc) deeply excavate, and the depressed

spaces squamose. The last-mentioned insect approaches Synthlibonotus, Schonh. (type

S. rufipes, Lacord.), but differs from it in having less inflated, 10-striate elytra, the

scrobes more strictly lateral, the metathoracic episterna more dilated anteriorly, &c.

de Pirris (Underwood), Cariblanco, Carrillo (U.S. Nat. Ilus.).

Sent us in abundance from La Palma and Irazu. Separable at once from its allies

by the very shining, almost glabrous, greasy-looking, black body, and the inflated

elytra, with the flanks conspicuously nodose below the base and the humeri prominent.

The spiniform prominences at the apex vary in development, and are often considerably

lengthened in the female. C. adipatus has quite the facies of an Otiorhynchus.

broad submarginal stripe on each elytron, rufous; the upper surface (except the dise of the prothorax

and the sutural region of the elytra) and the sides of the body beneath clothed when fresh with very

minute, scattered, blue or cinereous scales, which are soon abraded. Head and rostrum finely punctate,

the rostrum tricarinate, the inter-ocular space depressed and feebly foveate; eyes large, not prominent.

Prothorax slightly broader than long, subcylindrical, obliquely narrowed anteriorly, broadly depressed or

flattened down the middle and sometimes with a short median suleus behind, feebly bisinuate at the base ;

punctuation, the flanks rugose. Scutellum small. Elytra oblong-ovalin ¢, broader in Q, transversely

excavate at the base, somewhat tumid at the sides below the shoulders (appearing obliquely narrowed

anteriorly), flattened along the suture, gradually sloping outwards, and abruptly declivous at the apex,

tne humeri not prominent, the apices acuminate, feebly mucronate in ¢; finely seriate-punctate, the

interstices broad, flat, finely granulate towards the sides. First ventral segment flattened or depressed

down the middle in ¢. Legs rather slender, the femora and tibie almost smooth. Wings fully

developed or rudimentary.

Hab. Costa Rica (coll. Solari), La Palma 1600-1700 metres (Biolley), Azahar de

Cartago (Underwood).

Described from seven examples, two of which belong to Signor Solari. Easily

recognizable by the somewhat concave upper surface of the body (as seen in profile),

the rufo-vittate, sloping lateral portions of the elytra, and the non-prominent humeri.

The wings are fully developed in one specimen, and rudimentary in another, of the

two individuals ( @ ) softened for examination.

3. Chauliopleurus quadrifoveatus, sp.n. (Tab. XII. figg. 19, 19a, 2.)

Moderately elongate, oval, shining, black, the legs sometimes piceous; the prothoracic cavity, the lateral

excavations of the elytra, and an oblong space on the flanks between the latter and the lower margin

somewhat densely clothed with white, green, or blue scales ; the rest of the upper surface and the sides

foveolate and finely punctate. Scutellum transverse, small. Elytra broad, slightly narrower in d,

inflated, oval, usually more or less tumid on the flanks at a little below the shoulder, with a common,

deep, transverse excavation at the base, and a very large, broad, oblong or oblique depression on each

side of it between the third interstice and the outer margin, the apices conjointly produced and usually

obliquely truncate or mucronate at the tip ; punctate-striate, the third interstice smooth, widened, sinuous,

I have seen eight specimens of this peculiar insect, varying in the colour of the

scales on the excavate portions of the surface (which are often covered with an

ochreous exudation) and in the greater or less inflation of the elytra. The sutural

region of the elytra to about the middle and the raised portions of the prothorax are

usually almost bare. ‘The deep, angular, plicate depression on each side of the second

ventral segment is noteworthy. |

A single species from the Pacific slope of Guatemala is referred to this genus *, the

type of which is Curculio thunbergi, Dalm.; both these insects (and HL. adamantinus,

Germ., also) have the surface of the body densely viridi-squamose, and the prothorax

and elytra albo-lineate. The chief structural characters are as follows :—

Rostrum longer than broad, dilated inferiorly towards the apex, with a densely squamose, sharply-defined,

_ triangular nasal plate, and the upper portion parallel-sided, the gene not or feebly marginate, the scrobes

lateral and running direct to the lower anterior portion of the eyes, the latter oval, large, and not very

prominent ; scutellum well developed; elytra lobed at the base, regularly 10-striate, the outer strie

entire; anterior tibiz abruptly bowed, stout, denticulate and unguiculate; posterior tibie laminate and

densely clothed with long scales at the apex, the glabrous articular surface short and feebly cavernous.

é. Elongate, narrow, black, the legs and antennz piceous ; thickly clothed with glittering pale green scales,

the prothorax with two lines on the dise and another on each flank (all of them extending on to the head),

and the elytra with the suture, the third interstice, and a broad stripe along the flanks, more densely set

with imbricate whitish scales. Head and rostrum rugulosely punctate, the rostrum much longer than

between the eyes and a smooth space behind them; eyes oval, large, somewhat depressed ; antenne

rather slender, joints 1 and 2 of the funiculus subequal in length, the others shorter and obconic. Pro-

thorax gradually narrowed anteriorly, the sides parallel behind, the base deeply bisinuate ; rugulosely

punctate. Elytra narrowing from about the middle, bisinuate at the base, produced at the apex, the

apices each armed with a prominent tooth at the sutural angle, the humeri obtuse and somewhat tumid;

finely punctate-striate, the interstices rugulose, 1 (suture), 3, and 7 more or less raised. First ventral

segment hollowed down the middle. Anterior tibia strongly, and the intermediate pair feebly, unguiculate;

the anterior pair (fig. 206) stout, abruptly bowed, closely denticulate, and ciliate within.

Length 83, breadth 23 millim.

Hab. GuateMaLa, Zapote (Champion).

One specimen. Not unlike the Brazilian £. thunbergi, Dalm. (=pentachordius,

Germ.), but less elongate, the rostrum, antenne, and prothorax shorter, the scales

larger and less densely packed, the elytra each armed witha strong tooth at the sutural

angle. ‘The anterior tibiz are similarly bowed in the two species.

DECASTICHA, gen. nov.

Rostrum a little longer than broad, the upper portion obliquely divergent on each side of the triangular smooth

nasal plate, the scrobes lateral, deep, curved, and descending ; eyes not strictly lateral, moderately large,

rounded ; antenne rather slender; prothorax feebly bisinuate at the base; scutellum well-developed ;

elytra much wider than the prothorax, separately rounded at the base, with the humeri moderately

prominent and oblique in front, 10-striate, the outer stric entire; legs rather slender; tibize without

conspicuous denticles on their inner cdge, the anterior and intermediate pairs unguiculate, the posterior

pair laminate at the apex and with the glabrous articular surface short and cavernous ; body winged,

oblong or elongate, squamose.

Type, D. subocellata.

The four Costa Rican or Panama insects referred to this genus are closely related

inter se, though not very similar in general appearance. ‘The 10-striate elytra

separates them from Lxophthalmus; and the non-squamose nasal plate, the less

abruptly bowed anterior tibie, the rounded eyes, the non-lobate base of the elytra,

&c., distinguish them from Eustales (type Curculio thunbergi, Dalm.). D. subocellata

superficially resembles Exophthalmus obsoletus (Oliv.) and D. decemguttata is marked

like E. jekelianus (White). Decasticha will include at least one undescribed Colombian

form (Eustales gemmeus, Klug, in litt.) in the British Museum.

1. Decasticha subocellata, sp.n. (Tab. XII. fig. 21, 2.)

Q. Elongate, black, densely clothed with whitish scales, the prothorax and elytra confusedly variegate on the

disc with fuscous scales, those on the elytra enclosing numerous small and two larger (longitudinally

placed, transverse or rounded) whitish spots, the flanks of the elytra with a dark-edged spot at about the

basal fourth; the surface also set with minute, scattered, decumbent setee. Head and rostrum densely,

finely punctate, the rostrum depressed down the middle to the feeble inter-antennal ridge and finely

canaliculate to the small inter-ocular fovea; antenne rather slender, the scape about reaching the

posterior margin of the eyes, the latter rounded. Prothorax broader than long, bisinuate at the base,

obliquely narrowed anteriorly ; densely, finely punctate, and with some coarse scattered punctures along

the sides, the disc incompletely suleate down the middle and strongly, arcuately depressed at the base.

2. Decasticha quadriplagiata, sp.n. (Tab. XII. fig. 22, 2.) |

Q. Elongate, subfusiform, black; densely clothed with small cinereous scales, the elytra confluently or

asymmetrically nigro- or fusco-annulate to near the apical declivity (the prothorax also in one specimen

with four irregular dark annuli on the disc), and each with two large, oblong, subangular, dark-edged

spots on the outer part of the disc and a smaller spot near the lower margin (the enclosed spaces whitish,

when the yellow exudation is removed); the surface also set with a few scattered, minute, decumbent

sete. Head and rostrum densely, finely punctate, the latter with a smooth median line extending back-

ward to the narrow inter-ocular fovea; eyes convex; antenne rather slender, joints 1 and 2 of the

funiculus equal in length. Prothorax transverse, bisinuate at the base, the sides parallel behind and

obliquely converging anteriorly ; densely, finely punctate, and with some coarse scattered punctures along

the sides, the disc broadly flattened down the middle, obsoletely canaliculate posteriorly, and arcuately

depressed at the base. Scutellum small, flattened. Elytra elongate, subparallel in their basal half,

acuminate and feebly mucronate at the tip, broadiy flattened towards the suture; very finely punctate-

striate, the punctures becoming larger on the disc, the interstices densely punctulate, flat, 5 convex at

its point of termination.

closely punctulate, the latter canaliculate to the inter-ocular fovea ; eyes somewhat depressed; antenne

slender. Prothorax transverse, feebly bisinuate at the base, obliquely narrowed anteriorly, densely

punctulate, and with a few widely scattered coarse punctures, which become more numerous along the

sides, the disc broadly depressed and uneven down the middle and sometimes with a small oblong fovea

opposite the scutellum. Elytra elongate, subparallel in their basal half, acuminate and mucronate at the

Bugaba (Champion).

Found in profusion at Cerro Zunil. The vestiture varies in colour from almost

uniformly brown to cinereous, with darker markings, the apical declivity being always

paler than the space between the dorsal ridges; the Nicaraguan and Costa Rican

examples have patches of green scales intermixed, and those from Panama are whitish,

with the rostrum, head, and front tibie cupreous. The prothorax has the coarse

granules on the median portion of the disc bare, so that the sides appear broadly

vittate. The suture of the elytra is raised on each side of the scutellum, and the

prominent curved ridge running down the third interstice terminates abruptly in

a large tubercle at the commencement of the apical declivity, there being another

tubercle at the end of the fifth; the seriate punctures are usually each placed in

a shallow transverse foveiform depression, sometimes appearing quite small till the

scales are removed. ‘The wing (fig. 256) in the large females measures 15 mm.

A Costa Rican specimen is figured.

2. Cleoteges granulosus, sp.n. (Tab. XII. figg. 26, 264, 3.)

scales, the elytra usually with small patches of green scales intermixed and the apical declivity abruptly

paler, the prothorax often with a green patch at each hind angle and another on the flanks, the

cinereous scales rarely predominating over the whole surface ; the elytral interstices each with a row of

semierect stiff sete. Head and rostrum densely, finely punctate, the rostrum bicarinate above, appearing

hollowed down the middle from the transverse inter-antennal ridge, the latter extending obliquely

forwards on each side ; eyes very large, oval as seen from above, separated by about half the width of

the rostrum. Prothorax transverse, slightly rounded at the sides, the hind angles rather prominent ;

densely, finely punctate and sparsely granulate, the granules usually a little larger along each side of

the shallow median sulcus. Elytra very much wider than the prothorax, oblong-subtriangular in ¢,

broader and subparallel to the middle in 2, not or obsoletely mucronate at the tip; punctate-striate,

the interstices densely punctulate and often sparsely granulate, the outer ones more or less convex,

The scales vary in colour, but are usually darker on the flattened dorsal portion of

the elytra, and there are often small green patches on the flanks and hind angles

of the prothorax, as well as on the wing-cases.

of irregular spots or streaks on the outer half of the disc before the middle, extending to beneath the

humeri, a transverse interrupted fascia between the subapical tubercles, and an oblong patch on the

flanks, and various small scattered patches on the under surface, golden-green ; the elytral surface also

set with scattered, curled, decumbent sete, similar to those on the legs. Head and rostrum densely,

rugulosely punctate, the rostrum obsoletely bicarinate towards the feeble transverse inter-antennal

ridge; eyes large. Prothorax convex, a little broader than long, rounded at the sides, shallowly sulcate

NAUPACTOPSIS, gen. nov.

Prothorax and elytra truncate at the base; elytra in d oblong and but little wider than the prothorax,

in @ much broader and widened to middle, with additional, interposed, abbreviated strie on the outer

part of the disc, the outer striz entire, the humeri obtuse or angular, the lower margin sinuate ; rostrum

broad, subquadrate, the scrobes lateral and obliquely descending, becoming shallow and much wider

behind, the nasal plate triangular; eyes large, not strictly lateral, not prominent; joints 1 and 2 of the

funiculus subequal in length; scutellum small; mesothoracic epimera moderately large, oblique ;

metathoracic episterna dilated anteriorly ; first ventral suture arcuate ; posterior tibix narrowly laminate

and biciliate at the apex, the glabrous articular surface very large and cavernous; body oblong, more or

less squamose ; wings wanting or rudimentary.

Type, WV. delumbis.

The Mexican insects from which the above characters are taken may be briefly

described as apterous Exophthalmi, with the elytra in the males very little wider than

the prothorax, and the upper marginal border of the scrobes obliterated posteriorly,

so that they appear to be dilated towards the eyes. These forms were rightly rejected

by Dr. Sharp when he enumerated our apterous Otiorhynchids, as they have a

distinctly exposed scutellum and the meso- and metasternal side-pieces shaped as in

the alate representatives of the group, and therefore belong to Horn’s Division II.

The sexes of NV. delumbis and WN. auropictus are so dissimilar that they might be

mistaken for separate species.

one-fourth or one-fifth from the apex; the surface also set with a few very short, curled, pallid sete.

Head and rostrum rugosely punctate, the rostrum not or obsoletely carinate, the nasal plate triangular

and limited behind by a v-shaped ridge, the inter-ocular fovea small or wanting; joints 1 and 2 of

the funiculus equal in length; eyes rather prominent. Prothorax ( ¢) convex, about as long as broad,

in having the prothorax more closely foveato-punctate in both sexes; the elytra

irregularly striate towards the sides anteriorly, relatively shorter and more narrowly

acuminate at the apex in the female, and with subangular humeri in the male. The

markings, which are easily abraded, are somewhat different from those of NV. auropictus,

the prothoracic vitte being placed further inwards and the streak on the elytra

duplicated towards the base ; the striz, too, are more irregular on the disc.

2. Naupactopsis auropictus, sp.n. (Tab. XIII. figg. 1, 3; 2, 2.)

Elongate, rather convex, narrow, and subelliptic (¢), broad and subpyriform ( @ ), black or piceous, the legs

varying in colour from black to ferruginous; clothed with minute brown, cinereous, or coppery scales,

the prothorax with a narrow stripe on each side of larger, imbricate, whitish, green, cupreous, or golden

scales which is often interruptedly continued down the dise of each elytron, the flanks of the latter

and the larger punctures of the upper surface frequently bearing similar metallic scales ; the surface also

set with small, decumbent, scattered pallid sete. Head and rostrum densely, finely punctate, the

rostrum slightly longer than broad, feebly or obsoletely carinate down the middle, the nasal plate short,

the inter-ocular fovea small; antennal scape reaching beyond the eyes, the latter large and depressed.

Prothorax about as long as broad, rounded at the sides, in the ¢ scarcely narrower at the apex than

at the base, in the 2 broader behind and subtransverse, truncate at the base, narrowly suleate down

the middle; impressed with scattered irregular foveiform punctures intermixed with a fine dense

interstitial punctuation. Scutellum small, LElytra oblong-oval in ¢, broader, widened to the middle,

the base, the interstices densely punctulate, narrow and uneven in 4, broad and sometimes flat in 2.

Var.? The prothorax with a broad submarginal vitta, which is continued down the disc of the elytra to the

apex, and a broad stripe along the lower margin of the latter, densely clothed with greenish ( ¢) or

golden-cupreous ( 2 ) scales; the legs in great part ferruginous.

A very variable insect, and the sexes dissimilar im form. The seriate punctures on

the elytra are larger, scattered, and foveiform in the more rugose examples, and often

bear a few metallic scales, like those on the submarginal vitte of the prothorax. The

penis-sheath of the male is broad, somewhat pointed at the tip. The second joint of

the funiculus is somewhat elongated in the female. A long series of both sexes has

been sent us by Hége. The variety ? is represented by a pair obtained from M. Donckier

3. Naupactopsis sitonoides, sp.n. (Tab. XIII. fig. 3, 2.)

Oblong-oval, moderately convex, dull, nigro-piceous; densely clothed with small coppery-brown scales, with

whitish scales intermixed, these latter becoming more numerous on the head, along the sides of the

prothorax, and on the humeri and sides of the elytra, the surface also set with short, curled, scattered

hairs. Head and rostrum densely, rugulosely punctate, the rostrum about as broad as long and obsoletely

carinate to the small inter-ocular fovea; antenne comparatively short, the scape barely reaching the

posterior margin of the eyes, the latter widely separated and not prominent. Prothorax broader than

One specimen. ‘This insect has quite the facies of a Sitones or Tanymecus.

Compared with WV. auropictus and N. delumbis ( 2 ), it has the elytra more rounded at

prothorax long, cylindrical or subcylindrical, constricted in front, truncate or feebly bisinuate at the

base ; scutellum visible ; elytra elongate, 10-striate, the striz placed in pairs between the alternately

raised interstices and their position indicated by very fine impressed lines visible through the dense

vestiture, the outer stris approximate or coalescent from about the basal fourth, the small seriate

punctures each placed in a foveiform depression, the humeri obtuse or subangular; mesothoracic epimera

narrow, oblique ; metathoracic episterna narrow, dilated inwardly in front; legs stout ; femora unarmed ;

posterior pair laminate at the apex, their articular surface large, cavernous, and not entirely glabrous ;

body elongate, apterous *, squamose.

Type, WM. bifoveatus.

The three species belonging to this genus agree remarkably well inter se, not only

in the general form of the rostrum, the peculiar elytral sculpture, &c., but in having

two small, longitudinally placed, bare, polished foveee on the disc of the prothorax.

The meso- and metasternal side-pieces are shaped as in the winged Otiorhynchids, and

there is a distinctly visible scutellum, though the wings are doubtless wanting or

rudimentary and the elytra connate. ‘These insects are from Mexico or Guatemala,

and all of them appear to be very rare. Pactorrhinus, Ancey, type P. grisescens,

from Arizona [Le Naturaliste, i. 485 (Oct. 1881)], may be an allied genus f.

oblong polished shining fovea, and various other large, confluent, irregular, foveiform depressions.

Scutellum well developed, convex. Elytra not wider than the prothorax, elongate, subparallel from the

obliquely rounded humeri to about the middle, transversely depressed at the base and conjointly

produced at the apex; with rows of coarse punctures placed along extremely fine geminate strie, the

interstices uneven, densely, finely punctate, 3, 5, 7, and 9 widened and costate, 3, 7, and 9 partly bare.

Legs very stout; anterior tibie strongly bowed.

Hab. Guatemata, San Gerénimo in Baja Vera Paz (Champion).

Two specimens. A remarkably distinct form, easily separable from the following

by the sharply albo-lineate fifth elytral interstice, the prominent scutellum, and the

very coarsely wrinkled, foveolate prothorax, the two cblong, bare, polished fovee on

which form an interrupted median sulcus.

2. Mazenes geminatus, sp.n. (Tab. XIII. fig. 5, ¢.)

Elongate, narrow, piceous; above densely clothed with brown scales, with green and ochreous scales

intermixed, the latter mainly confined to the foveiform depressions, the under surface uniformly viridi-

squamose, the surface also set with stiff decumbent sete similar to those on the legs. Head and rostrum

densely, finely punctate, the oblique ridges on the rostrum broad and not very conspicuous; antennal

scape subclavate at the tip; eyes feebly convex. Prothorax a little longer than broad, cylindrical,

narrowed and feebly constricted in front, densely, finely punctate; transversely wrinkled and irregularly

foveolate, the disc with two longitudinally placed, small, polished fovese. Scutellum very small. Elytra

elongate, very little wider than the prothorax, subparallel in their basal third, transversely depressed at

the base, the humeri oblique, subangular; with rows of moderately coarse punctures placed along

extremely fine geminate stria, the interstices uneven, densely, finely punctate, 3, 5, 7, and 9 widened

and more or less raised, the outer striz coalescent from a little below the base. Legs stout.

Length 144, breadth 3? millim. (<.)

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

One specimen. More cylindrical than M. difoveatus, the antennal scape more

slender, the excavations on the prothorax much shallower, the scutellum smaller, the

elytra at the base a little broader than the prothorax, and with the alternate interstices

wider and less raised, the under surface uniformly clothed with pale green scales.

It is probable that the green scales are partly abraded on the upper surface.

3. Mazenes lineatus, sp. n. (Tab. XIII. fig. 6, 2.)

Elongate, widened posteriorly, piceous ; thickly clothed with brown, pale ochreous, and whitish scales—the

ochreous scales on the elytra condensed into lines on the depressed portions of the surface and those on

the prothorax placed in the transverse furrows, the white scales on the elytra condensed into a faint

stripe on the fifth interstice and an angular patch near the apex; the scales on the under surface and

legs cinereous or whitish, with brown scales intermixed ; the apex of the elytra and the under surface also

set with bristly decumbent sete, similar to those on the legs. Head and rostrum densely, finely punctate,

Group PLATYOMINA.

Cyphina, Horn (part-).

Cyphides (part.) and Eustylides, Lacordaire.

Under this heading are placed various genera with the scrobes superior (in great

part or wholly exposed from above), short (or if continued backwards becoming

shallow and squamose behind), parallel or divergent; the eyes not strictly lateral ;

the elytra 10-striate, the outer striz# coalescent from about the basal third or free ;

the anterior tibie unguiculate or unarmed; the posterior tibia laminate at the apex

(corbels closed); the tarsal claws free (except in Aphrastus) ; the wings fully developed

(except in a few species of Hustylus) ; and the body densely squamose.

The following genera belong here:—Platyomus, Compsus, Artipus, Brachystylus,

Brachyomus, Eustylus, Synthlibonotus, and Aphrastus, Schonherr, Pseudocyphus,

Schaeffer, Zemnoscapus, Chevrolat, &c. Aphrastus agrees with Phyllobius in having

the tarsal claws connate and the scrobes superior; but in the last-named genus the

scrobes are open behind, foveiform, and subapical, and the corbels are open.

Pseudocyphus has the rostrum less widened anteriorly than in the allied forms

({ Platyomus, &c.) and the scrobes sublateral; this genus would therefore seem to be

better placed amongst the Cyphina, from which it differs, however, in having the eyes not

strictly lateral. Hustylus and Brachystylus (with Aptolemus) were placed by Lacordaire

in a separate Group, “‘ Eustylides,” near his “ Phyllobiides.” The six genera represented

in our region may be separated thus :—

a, Tarsal claws free.

Pseudocyphus, Schaeffer, Bull. Brooklyn Instit. i. p. 179 (1905).

Rostrum very stout, not longer than the head, not dilated anteriorly ; the upper portion sulcate, narrowing

forwards, sharply produced on each side between the points of insertion of the antenne, and excavate

and foveate in the middle; the nasal plate depressed, long, triangular, squamose, and emarginate in

front; the gene triangularly excised ; the scrobes in great part visible from above, curved, sublateral,

converging forwards, and not extending below the eyes. Eyes large, oval (as seen in profile), not

strictly lateral. Antennal scape curved, flattened, more or less dilated or clavate. Prothorax short,

bisinuate at the base, truncate in front. Scutellum well developed. LElytra subtriangular (3) or

oblong (2), 10-striate, the outer strie entire, the humeri prominent. Tibie unarmed at the inner

apical angle in both sexes; posterior pair laminate and squamose at the apex, the articular surface

glabrous and ascending. Body winged, densely squamose.

Under this genus are placed various moderate-sized Mexican and Guatemalan forms

nearly related to the S.-American Platyomus mutabilis, diane, &c., all of which differ

from the type of Platyomus (Cyphus cultricollis, Germ.) in having large, oval, moderately

prominent eyes, an apically dilated scape, a subcylindrical or subconical prothorax,

non-tuberculate elytra, &c. ‘The type of Pseudocyphus, P. fleaicaulis, Schaeff., from

Brownsville, Texas, for specimens of which we are indebted to Mr. Wickham and the

author (Tab. XIII. fige. 7, 7a, 3), has the head relatively broader, the antenne

stouter, and the outer joints of the funiculus more transverse than in the Central-

American species, but these differences are insufficient for generic separation *.

* The allied genus Chamelops (type C. munita, Kirsch, from Colombia) has the scape strongly curved,

slender at the base, and greatly dilated outwards, the funiculus slender, the elytra strongly lobed at the base,

the legs very hairy, &c. Temnoscapus fissirostris, Chevr., from Bogota (the type of which I have seen), is

another allied form; it superficially resembles the female of Stetrarrhinus conicollis, differing from that insect

in the short antenne, with apically dilated curved scape, the not strictly lateral eyes, the non-descending

scrobes, &c.

part of the Polochic valley), all the localities being on the Atlantic slope. P. chrysopus

is represented in Yucatan by P. zebra, which has still more widely separated seriate

punctures on the elytra and the dark post-median fascia curved or oblique.

This genus, like Cyphus, extends northward to the United States. It includes a

large number of South American forms, most of which are so densely clothed with

chalky-white or green scales that the sculpture cannot be properly seen. ‘The essential

characters of the species here referred to Compsus (the type of which is Cyphus

acrolithus, Germ.) are :—

Rostrum broad, widened anteriorly, emarginate at the sides and apex, the upper portion obliquely bifurcate

anteriorly, the nasal plate wide, triangular, bare, the scrobes visible from above, subangulate, not

reaching to beneath the eyes ; eyes not strictly lateral, more or less rounded (obliquely truncate in front

in C. argyreus, L.); antennal scape flattened, narrow, feebly clavate ; scutellum well developed ; elytra

regularly 10-striate, the outer stria coalescent from the basal third, the humeri prominent; anterior

tibia unguiculate, not denticulate within; posterior tibia narrowly laminate at the apex, the space

between the marginal cilia bare, the articular surface large, feebly ascending or subterminal, squamose ;

body winged, densely squamose.

The scales in some of the species vary in colour from green to white (C. auri-

cephalus, &c.), and several of the southern forms are ornamented with small blue

evanescent spots, this colour sometimes extending to the legs also. ‘Ihe elytra in the

females are often more distinctly divergent or mucronate at the tip than in the males.

C. carinirostris, Boh., has two additional abbreviated striz on the elytra, the articular

surface of the hind tibie glabrous, &c., and it is here placed under Lvophthalmus

(antea, p. 254).

a. Rostrum carinate anteriorly ; elytra each with a bare black spot on the

middle of the disc, the seriate punctures scattered, the alternate inter-

stices scarcely more raised than the others, and the striz normal ; legs

1. Compsus ceeruleipes, sp.n. (Tab. XIII. figg. 15, 15a, ¢.)

Elongate, black; densely clothed with chalky-white scales, the legs (the basal half or more of the femora

excepted) in great part czeruleous, the elytra each with three very small bare black spots (one on the

shoulder, one at the middle of the disc, and one at the end of the fifth interstice), and the prothorax in

the Bugaba specimen with three similar spots along the anterior margin; the surface also set with

minute, scattered, adpressed hair-like scales, which become longer on the body beneath. Rostrum longer

than the head, feebly carinate down the middle anteriorly, and obliquely grooved on each side of this

towards the base, the upper portion obliquely divergent on each side in front, the scrobes subangular

and obliquely descending to beneath the eyes, the latter rounded and convex ; antennal scape reaching

to a little beyond the eyes. Prothorax slightly broader than long, strongly bisinuate at the base,

hollowed down the middle, irregularly foveato-punctate. Elytra elongate-triangular, flattened on the

disc, separately rounded at the base, acuminately produced at the apex, the apices divergent and

dentiform, the humeri tumid; with rows of small, oblong, somewhat widely separated, bare punctures,

each placed in a large shallow fovea, the interstices 3 and 5 very slightly raised.

Length 133-18, breadth 43-6} millim. (¢.)

fab. Costa Rica, Pozo Azul (Underwood) ; Panama, Bugaba (Champion).

Two specimens. Distinguishable from the other Central American forms by the

less raised alternate elytral interstices, the three small bare spots on each wing-case,

and the partly blue legs; and from C. lacteus (F.) by the more scattered seriate

punctures on the elytra, the elytra themselves less acuminate at the apex and not

so strongly lobed at the base. There are various allied unnamed §.-American species

in the British Museum *, some of which have doubtless been described by Kirsch #.

* Compsus 18-signatus, sp.n. (Tab. XIII. fig. 16.)—Less elongate than C. cwruleipes; the prothorax

and elytra together with 18 or 19 very small blue spots—the prothorax with three on the anterior

margin, four in a transverse row across the middle (the outer one on the flanks), and one at the base

(sometimes obsolete), and the elytra with five in a transverse series just below the base, one at the

middle of the disc, one in a line with it on the flanks, and one at the end of the fifth interstice ;

the antennal scape, knees, tibie, and tarsi more or less blue; the rostrum neither carinate nor obliquely

grooved, the anterior portion less divergent at the sides in front; the elytra with the alternate inter-

stices slightly raised, the seriate punctures within the foves squamose, the apices moderately produced,

conjointly rounded ( 9?) or bluntly subdentate (¢?). Length 10-123, breadth 33-42 millim.

Hab. Mexico? and Vengzvurta (Mus. Brit.).

Two specimens, labelled with the MS. name C. 18-signatus, Chevr. The Mexican habitat seems doubtful.

The coarser, scattered, foveiform, seriate punctures, the less raised subapical portion of the third interstice,

and the different position of the subapical spot on the elytra distinguish the present species from Q. nigro-

punctatus, apart frem the colour of the legs, &c.

The specimens of this species before me (including a long series from Tampico)

vary greatly in size and in the colour of the scales—from green to white or pale

brown, the head, rostrum, and legs being often cupreous in the green typical form.

The southern examples are more elongate, uniformly white or brownish *, and have

the alternate elytral interstices 3, 5, and 7 strongly costate and the apices more

produced; but they are connected with C. auricephalus by intermediate forms. The

prothorax is trisulcate, and often more widened posteriorly in the female than in

the male; the eyes, too, are sometimes rather depressed in the former sex. Found on

Phoradendron, Ambrosia, Gossypium, and Acacia °.

3. Compsus nigropunctatus, sp.n. (Tab. XIII. fig. 19.)

Elongate, black, densely clothed (the punctures included) with chalky-white scales, the elytra each with three

or four small bare black spots—-one on the fourth or fifth interstice below the base (sometimes obsolete),

one at the middle of the disc, one in a line with it on the outer margin, and one on the third interstice

towards the apex,—the prothorax also sometimes with three or five small black spots (three on the

anterior margin and one on each side of the disc towards the base). Rostrum hollowed and obsoletely

sulcate anteriorly, the upper portion obliquely divergent on each side in front, the scrobes descending

for a short distance before the eyes, the latter rounded and convex; antennal scape reaching to a little

beyond the eyes. Prothorax transverse, deeply bisinuate at the base, slightly rounded at the sides,

broadly flattened or hollowed down the middle. Elytra elongate-triangular, flattened on the disc, lobed

at the base, acuminate at the apex, the apices dentiform ; with rows of fine, subapproximate punctures

placed in very shallow fovex, the third interstice gradually becoming more raised to the apical declivity

and then abruptly declivous, the fifth also raised posteriorly and the seventh anteriorly.

Three specimens, varying in the number of the spots on the prothorax and elytra,

the individual from Chiriqui having the prothorax almost immaculate. The third

elytral interstice becomes more prominent and cariniform posteriorly, but it is not

tuberculate at the commencement of the apical declivity as in C. cretaceus (F.) and

some other allied S..American forms. The seriate punctures are closely placed, fine,

and shallow, and the sutural region is flattened. The minute scattered hair-like scales

are just traceable. C. quadrisignatus and C. bisignatus, Boh., are somewhat similarly

maculate.

EUSTYLUS.

Eustylus, Schonherr, Gen. Cure. vii. 1, p. 40 (1843) ; Lacordaire, Gen. Col. vi. p. 207.

Schénherr referred two winged species to this genus—one with the anterior femora

toothed (£. puber, Oliv., from Cclombia*), the other with the anterior femora unarmed

(H. striatus, Boh., from Mexico). Amongst the various new forms now added there

are representatives of each of these sections, and three with rudimentary wings.

They agree in the following characters :—

Rostrum widened anteriorly, the scrobes short, deep, superior, and wholly exposed from above, the bare nasal

plate more or less concave, and limited behind by a v- or u-shaped ridge; antennal scape stout or

moderately stout, reaching at least to the front of the prothorax; eyes prominent, not strictly lateral ;

prothorax subcylindrical; scutellum well developed orsmall; elytra 10-striate, the outer strix coalescent

from the basal third or free (H. ruptus and H. verepacis), the humeri prominent in the winged forms ;

metathoracic episterna dilated anteriorly ; anterior femora toothed or unarmed; anterior and inter-

mediate tibiz unguiculate ; tarsal claws free; wings fully developed or Tadimentary ; body oblong or

elongate, squamose, and sometimes conspicuously setose,

E. grypsatus superficially resembles a Phyllobius, from which it differs in having

sharply defined, deep, oblong scrobes and free tarsal claws. The fusion or separation

of the outer striz of the elytra and the development of the wings prove to be unstable

characters in Lustylus.

Elongate, narrow (db), broader (@), piceous; densely clothed above with brown and whitish scales, the

latter condensed into two vittz on the disc of the prothorax and a stripe down each of the alternate

elytral interstices, the elytra also each with three subquadrate blackish spots (two on the third, and one

on the seventh interstice), and sometimes another small spot towards the apex; the scales on the under

surface and along the flanks of the prothorax and elytra almost wholly whitish; the surface also set with

minute scattered decumbent hairs. Rostrum longer than broad, widened anteriorly, the short deep

scrobes converging posteriorly ; eyes very large, separated by about their own width as seen from above ;

antenne fully one-half the length of the body in ¢, the scape stout and reaching considerably beyond

the front margin of the prothorax, joint 2 of the funiculus longer than 1. Prothorax slightly broader

than long, narrowed and feebly constricted anteriorly, flattened down the middle of the disc, the

punctures covered by the vestiture. Scutellum large. LElytra elongate-subtriangular in ¢, broader

and gradually widened to the middle in 2, the humeri prominent; punctate-striate, the alternate dorsal

interstices costate. Anterior femora clavate and sharply dentate. Anterior and intermediate tibiz

strongly unguiculate in both sexes.

Length 7-10, breadth 21-33 millim. (¢ @.)

Hab. Panama (Salvin), Volcan de Chiriqui, David (Champion), Tabernilla, Canal

Numerous examples, varying in the intensity of the markings, according to the

predominance of the whitish or of the brown scales, the darker individuals having

the white line on the fifth elytral interstice obsolete and the blackish spots very

conspicuous, and the paler specimens the spots almost obsolete. £. sexguttatus may

be at once separated from the Mexican EL. striatus by the sharply toothed anterior

femora, apart from its greater size, larger eyes, longer antenne, shorter prothorax, and

different elytral markings.

2. Kustylus setipennis, sp.n. (Tab. XIII. figg. 21, 21a, ¢.)

Elongate, narrow, rather convex, piceous; above densely clothed with brown scales, with cinereous or

greenish-white scales intermixed, the lighter ones sometimes condensed into two faint vitte on the

dise of the prothorax and a more or less distinct short oblique streak on the outer part of the elytra at

about the middle, the scales on the flanks in part, and those on the under surface, usually cinereous or

greenish-white; the elytra also set with numerous long, stiff, suberect, blunt setee down each of the

dorsal interstices, the rest of the surface with short curled decumbent scattered sete, the tibiae pilose

within. Head and rostrum canaliculate, the rostrum longer than broad, the scrobes subparallel as seen

from above, the head flattened between the eyes and abruptly convex behind them, the eyes rounded

and very prominent ; antennal scape very stout, reaching beyond the front margin of the prothorax,

joint 2 of the funiculus longer than 1. Prothorax much longer than broad, subcylindrical, slightly

rounded at the sides, sparsely punctate. Scutellum small. Elytra moderately elongate, punctate-

striate, the alternate dorsal interstices sometimes becoming more or less costate posteriorly, the humeri

not very prominent. Legs stout, anterior femora unarmed.

Hab. Mexico (Hegewisch, in coll. Sommer ').

An elongate, narrow form, variegate or lineate above with a dense clothing of light

and dark brown scales (the dark scales clustered into three narrow vitte on the

prothorax and various interrupted lines or small confluent spots on the elytra), and

also set with numerous, rather long, curved, adpressed, dark sete, the scales on the

under surface greyish or opalescent ; the short deep scrobes converging posteriorly ;

the eyes large and prominent; the antennal scape very stout and reaching the front

of the prothorax ; the prothorax elongate ; the elytra very gradually narrowing from

the base in ¢, broader, subparailel in their basal half, and more abruptly acuminate

in 2, the alternate interstices costate; the anterior femora unarmed. This species is

not represented in any of the extensive Mexican collections received by us, but there

are six examples of it in the Sommer collection, now in the Oxford University Museum,

the male figured having been kindly presented by Prof. Poulton.

4, Kustylus quadrigibbus, sp.n. (Tab. XIII. figg. 23, 23, 3.)

Moderately elongate, narrow (d ), broader (@ ), piceous or ferruginous ; densely clothed with coppery-brown

scales, the prothorax with an indication of two faint paler stripes on the disc and the elytra each with

sparsely punctate. Scutellum prominent. Elytra subparallel in their basal half in ¢, broader and

slightly widened posteriorly in @ , the humeri rather prominent ; coarsely punctate-striate, the alternate

dorsal interstices costate, the ridge on the third swollen into a large oblong tubercle at the commencement

of the apical declivity and a still broader tubercle below the base. Anterior femora unarmed. Anterior

and intermediate tibiw strongly unguiculate.

Length 64-8, breadth 21-3 millim. (¢ 2.)

Hab. Mexico, Toxpam in Vera Cruz (Saidé).

One pair. Recognizable by the two very large tubercles on each elytron—the one

below the base broad and occupying the space between the third and fifth rows of

punctures, the other oblong,—and the single dirty white oblique fascia on the disc.

The scrobes are less convergent behind than in /. striatus. The eyes in both these

insects have the appearance of being inserted at the base of the rostrum, owing to the

head being abruptly convex behind them.

5. Hustylus ruptus, sp.n. (Tab. XIII. fige. 24, 24a, ¢.)

3. Elongate, rather convex, piceous; above densely clothed with brown, coppery-brown, or greyish scales,

often with a few widely scattered metallic-green (or golden) scales intermixed, these latter predominating

at the base of the femora and on the ventral surface; the surface also set with short, scattered, adpressed

sete. Rostrum slightly longer than broad, widened forwards, with a smooth, anteriorly bifurcate, median

carina extending forwards to the well-defined, horseshoe-shaped, declivous, sulcate, subapical space, the

bare nasal plate concave and limited behind by a v-shaped ridge, the short scrobes converging posteriorly ;

eyes large, rounded, prominent ; antennal scape moderately stout, reaching the front of the prothorax,

joint 2 of the funiculus longer than 1. Prothorax cylindrical, a little longer than broad, slightly

narrowed towards the apex, feebly bisinuate at the base; coarsely punctate. Scutellum rather large.

Elytra elongate-triangular, at the base nearly twice as wide as the prothorax, the humeri very prominent;

closely, rather coarsely punctate-striate, the alternate interstices 3, 5, and 7 interruptedly costate, the

oblong elevation near the base of 3 tuberculiferm and very prominent, the outer strive free. Legs

moderately stout ; anterior and intermediate tibie strongly unguiculate.

Length 63-8, breadth 23-27 millim.

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

Six examples, evidently all males*. The elongate-triangular elytra, with prominent

humeri and interruptedly costate alternate interstices, the relatively narrow, cylindrical

prothorax, and the anteriorly bifurcate median carina of the rostrum, are the chiet

characters of E. ruptus. ‘The scales, too, are brown on the upper surface and metallic

green beneath. ‘The elytra are broader at the base than in #. serguttatus.

comatepec, Totosinapam (Sallé), Zacualtipam, Jalapa, Cerro de Palmas, Oaxaca

(fHége).

Apparently a common insect in Mexico, to judge from the numerous examples

available for examination. Fresh examples have the scales whitish or cinereous,

and the alternate elytral interstices interruptedly fusco-lineate to beyond the middle,

the prothorax sometimes with one or three darker vitte on the disc. The decumbent

setee along the elytral interstices are sometimes long and conspicuous. Specimens

occur with the scales brownish or cupreo-cinereous and the elytra faintly spotted with

greenish or dirty-white. The alternate elytral interstices are a little more raised than

the others, and the outer ones are coalescent from about the basal third. The head is

abruptly convex behind the eyes. The males are narrow, the females broader and

widened posteriorly. In four dirty examples (all more or less coated with an earthy-

looking exudation) the tarsal claws appear to be connate at the base, instead of free,

as in the type; they agree in all other respects with E. grypsatus.

7. Kustylus verepacis, sp.n. (Tab. XIII. fig. 26, 2.)

Moderately elongate, piceous or brown; thickly clothed with whitish, greenish-white, or bluish-white scales,

the prothorax sometimes with a slightly darker median vitta and the elytra variegated with small white

spots; the surface also set with short, scattered, decumbent sete, those on the elytra uniseriately

arranged down each interstice. Head and rostrum canaliculate, the rostrum broad, subquadrate, the

short deep scrobes becoming slightly divergent anteriorly, the bare nasal plate large, concave, and

limited behind by a v-shaped ridge; eyes very large, rounded, coarsely facetted; antennal scape

moderately stout, reaching the front margin of the prothorax, joint 2 of the funiculus longer than 1.

Prothorax subcylindrical, obliquely narrowed anteriorly, nearly as jong as broad, flattened down the

middle of the disc; sparsely, finely punctate. Scutellum large. Elytra elongate-subtriangular, broader

in Q, somewhat uneven, closely and conspicuously punctate-striate, the outer stric free, the interstices

feebly uniformly convex, the humeri prominent.

Seven specimens, a]l from Alta Vera Paz, assumed to include both sexes, though

the supposed females have the elytra narrowed from the base as in the males. Larger

than the Mexican £. grypsatus; the eyes larger and more coarsely facetted; the

prothorax relatively shorter; the elytra elongate-subtriangular in both sexes, the

shoulders more prominent, the outer striz free, the surface not fusco-lineate.

8. Eustylus chiriquensis, sp.n. (Tab. XIII. figg. 27, 27a, ¢.)

Obleng (3), somewhat pyriform (9), rather convex, piceous; densely clothed with coppery- or greyish-

brown scales, those on the apical declivity sometimes paler, and also set with scattered curled decumbent

sete. Head flattened and foveate between the eyes; rostrum short, broad, subquadrate, smooth, bare,

and shining down the middle, sulcate towards the large, bare, concave nasal plate, the latter limited

behind by a u-shaped ridge, the scrobes short, converging posteriorly ; eyes very large, rounded,

prominent; antennal scape moderately stout, reaching the front of the prothorax. Prothorax longer

than broad, somewhat rounded at the sides, very little narrower at the apex than at the base, the base

subtruncate ; with coarse scattered punctures intermixed with a fine interstitial punctuation. Scutellum

small. Elytra subparallel in their basal half in ¢, broader and widened to near the middle in 9°,

moderately produced at the apex, the humeri obliquely truncate, somewhat prominent in g, obtuse

in 9; uneven, coarsely punctate-striate, the alternate and outer dorsal interstices interruptedly costate,

the prominences becoming tuberculiform beyond the middle. Anterior femora unarmed. Anterior

and intermediate tibie unguiculate in both sexes, the anterior pair obsoletely denticulate. Wings

rudimentary.

Var, The elytra more produced at the apex, the alternate and outer dorsal interstices almost uninterruptedly

costate, the fifth sometimes with an oblong spot at about the basal fourth, or the scales of the apical

declivity, yellowish.

Length 53-7, breadth 14-2? millim. (¢ 2.)

Hab. Panama, Volcan de Chiriqui 4000-8000 feet, Caldera, Boquete, Pefia Blanca

(Champion).

A long series from the Volcan de Chiriqui; the variety is represented by three

examples from Pefia Blanca and one from Boquete. ‘This species differs from the

Guatemalan LE. cinericius in having a larger, concave, bare nasal plate; the rostram

smooth, bare, and more or less sulcate down the middle, and with the scrobes

converging posteriorly ; the alternate elytral interstices (in the typical form) inter-

ruptedly costate or tuberculate, and the humeri somewhat prominent in the male.

The scrobes are shorter than in Brachyomus and Synthlibonotus.

9. Hustylus subapterus, sp.n. (Tab. XIII. figg. 28, 284, ¢.)

Elongate, rather convex, narrow (3), broader (@), piceous or obscure ferruginous ; thickly clothed with

coppery-brown and greyish scales, the elytra sometimes with an oblique pallid spot or fascia on the

outer part of the disc at about the middle and an indeterminate or irregular transverse blackish patch

just beyond it, the scales on the under surface greyish ; the elytra also set with numerous semierect,

broad, oval or oblong, light and dark scales, which are chiefly clustered along the alternate dorsal

late, the rostrum about as long as broad, the scrobes slightly converging posteriorly, the head flattened

between the eyes, the latter rounded and very prominent; antennal scape gradually widened outwards,

reaching beyond the front of the prothorax, joints 1 and 2 of the funiculus subequal in length.

Prothorax longer than broad, slightly rounded at the sides, compressed before the middle, subtruncate at

the base, finely punctate. Scutellum very small. Elytra oblong-oval in ¢, broadened and widened to

the middle in 9, convex, conjointly produced at the apex, the humeri obliquely truncate and not

unarmed. Wings rudimentary.

Length 62-83, breadth 2-3 millim. (¢ 9.)

Hab. Mexico, Chiapas (Sallé); Guatemata, Quiché Mts. (Champion), Tecpan

(Conradi).

Six specimens, varying in the extent of the maculation of the elytra. The chief

characters of this species are—the long, gradually widened antennal scape; the

subquadrate rostrum with posteriorly converging scrobes; the comparatively smooth

semi-erect, intermixed setiform scales on the elytra; and the rudimentary condition

of the wings.

10. Eustylus cinericius, sp. n.

Elongate, rather convex, narrow (¢), broader (Q), piceous or ferruginous ; densely clothed with whitish,

cinereous, or greyish-brown scales (which often have a cupreous or greenish tinge in certain lights), the

elytra sometimes with a faint oblique darker fascia crossing the disc at about the middle (perhaps due

to discoloration), the surface also set with scattered, curled, short, decumbent sete. Head and rostrum

sulcate, the rostrum subquadrate, the scrobes subparallel, the head flattened between the eyes and

convex behind them, the latter rounded and very prominent ; antennal scape stout, reaching beyond the

front of the prothorax. Prothorax longer than broad, slightly rounded at the sides, subtruncate at the

base, and often feebly grooved down the middle; impressed with coarse scattered punctures, intermixed

with a fine close interstitial punctuation. Scutellum depressed or very small. Elytra moderately

long, slightly narrowed anteriorly in both sexes, broader and widened to near the middle in Q, the

sutural region broadly flattened to near the apical declivity, the humeri oblique and not prominent ;

coarsely punctate-striate, the alternate dorsal interstices raised. Legs stout; anterior femora unarmed.

Wings rudimentary.

Length 43-82, breadth 13-31 millim. (¢ @.)

Hab. GuateMaa, San Gerdnimo, Cerro Zunil (Champion).

Twenty-four specimens, those from San Gerdnimo with the vestiture more or less

discoloured by a brownish exudation. From ZH. subapterus the present species may be

known by the more convex basal portion of the head, the coarsely punctured prothorax,

the small curled elytral setee (which replace the intermixed broad, suberect scales), and

the almost uniform cinereous or greyish vestiture. The head and rostrum are found

to be deeply sulcate when the scales are removed. The metathoracic episterna are

dilated anteriorly, as in the fully-winged forms.

PSEUDEUSTYLUS, gen. nov.

Mentum large, almost filling the buccal cavity ; scrobes superior, broad, deep, extending backwards to the

eyes, becoming broader, shallower, and squamose behind the points of insertion of the antenne; nasal

plate triangular, on the same plane as the anterior part of the rostrum and not limited behind by a

conspicuous ridge; eyes very large; antenne with a long, feebly clavate, rather slender scape, an

elongated second joint to the funiculus, and an elongate club; scutellum large; elytra elongate,

10-striate, the outer striae free, the humeri prominent; anterior femora toothed ; anterior and inter-

mediate tibie unguiculate ; posterior tibiz narrowly lamellate at the apex, the glabrous articular surface

large and cavernous ; tarsal claws free; body winged, elongate, squamose; the other characters as in

Eustylus.

Type, P. cupreoviridis.

The two species from which the above characters are taken agree with Hustylus

puber and EL. sexguttatus in having toothed anterior femora, but the posteriorly

widened and produced scrobes and the flattened nasal plate readily distinguish them

from all the members of that genus.

PSEUDEUSTYLUS.—BRACHYSTYLUS. 297

1. Pseudeustylus cupreoviridis, sp.n. (Tab. XIII. fig. 29, 2.)

Moderately elongate, piceous ; densely squamose, the scales on the head, rostrum, and legs, on the anterior

margin and down the middle of the prothorax, along the base, suture, and outer part of the disc of the

elytra, and on part of the under surface, cupreous, those on the rest of the body green or greenish-

cinereous; the elytra also sparsely set with uniseriately arranged fine, stiff, erect setee, and the rest of

the surface with short decumbent hairs. Head and rostrum canaliculate; eyes very large, rounded,

convex ; antennal scape moderately stout, joint 2 of the funiculus considerably longer than 1. Prothorax

a little broader than long, subcylindrical, obliquely narrowing forwards, obsoletely canaliculate; with

coarse scattered punctures intermixed with a fine dense punctuation. Elytra elongate-triangular,

conspicuously punctate-striate, the interstices somewhat convex, the humeri prominent, the apices feebly

mucronate.

Length 73-91, breadth 23-3), millim. (¢ 9.)

Hab. Panama (Libbe, in Mus. Dresden), Bugaba (Champion).

Three males and one female. A remarkably distinct form, with the cupreous and

green portions of the surface sharply contrasted (recalling Pandeleteius erubescens and

Exophthalmus carneipes), the eyes very large, the scrobes wholly visible from above,

the anterior femora dentate.

2. Pseudeustylus cupreotinctus, sp.n. (Tab. XIII. figg. 30, 30a, 9.)

Q. Elongate, black, shining; above thickly clothed with cupreo-cinereous, the lower surface with whitish,

scales, the scales on the elytra here and there condensed into denser patches which are separated by

small partially denuded spaces (? abraded), and also set with short, scattered, decumbent, whitish sete.

Head and rostrum canaliculate, the rostrum longer than broad and with the upper portion parallel-

sided; eyes very large, somewhat depressed, oval as seen from above; antennew slender, the scape

feebly clavate at the tip, joint 2 of the funiculus twice as long as 1. Prothorax about as long as broad,

subcylindrical, obliquely narrowed anteriorly, interruptedly canaliculate; with coarse scattered punctures

intermixed with a fine interstitial punctuation. Elytra elongate, subparallel to beyond the middle, the

humeri prominent ; coarsely punctate-striate (the punctures appearing fine where covered by the scales),

the interstices flat on the disc, feebly convex towards the sides and apex.

Length 104, breadth 33 millim.

Hab. Guatemata, Cerro Zunil, Pacific slope (Champion).

One specimen. More elongate than P. cupreoviridis, the antenne more slender, the

eyes depressed, the elytra relatively longer, with the sete shorter and decumbent, the

scales uniformly coloured. ‘This species is extremely like Exophthalmus distigma, an

insect occurring in abundance at the same locality, but it is separable at a glance by

the superior scrobes, the longer, 10-striate elytra, and the dentate anterior femora.

HYPOPTUS.

Hypoptus (Jekel), Lacordaire, Gen. Col. vi. p. 271 (1863).

The principal characters of this genus (described by Lacordaire from females only)

are as follows :—

Rostrum widened at the apex, emarginate at the tip, the nasal plate reduced to a very short v-shaped piece,

the scrobes long, deep, obliquely descending to beneath the eyes, the latter large, depressed, transversely

oval; mentum large, flat, filling the buccal cavity; mandibles with a large scar in front; antennal

scape not extending beyond the anterior margin of the eyes; prothorax with large, rounded ocular

lobes; scutellum well developed; elytra much broader than the prothorax, oblong-subtriangular in dg,

subparallel in their basal half in 9, 10-striate, the outer striae free, the humeri prominent; femora

clavate, unarmed; tibiee feebly serrulate, unguiculate in ¢, without visible uncus in 2, the posterior

pair broadly laminate and squamose at the apex, and with the glabrous articular surface rather large

and moderately excavate; tarsal claws free; body oblong, squamose, fully winged.

Type, H. macularis, Lacord. (inedit.).

Hypoptus was based upon a very variable Central-American and Colombian insect,

line with it on the flanks (these two sometimes connected, or the outer one extending forward to the

shoulder), an angulate curved subapical fascia (in some specimens very broad, in others divided into two

spots), and (rarely) an oblong patch at the base of the suture,—the upper and under surfaces and the

legs occasionally with additional intermixed smaller patches of green or cupreous scales ; the surface also

Oblong-ovate, rather convex, black; very sparsely clothed with small cinereous scales, the elytra with some

denser patches or streaks of white scales along the flanks and towards the apex, the surface also set

with short, decumbent, scattered sete. Head and rostrum densely, confluently punctate, the rostrum

This genus includes a few small forms from the Southern United States, Mexico,

and Guatemala *. It may be known by the deep, inferiorly confluent scrobes, the

widely separated eyes, the prominent ocular lobes of the prothorax, the transverse,

rather large scutellum, the protuberant mesosternum, and the free tarsal claws.

The males have all the tibia more or less distinctly unguiculate (the uncus being

usually shorter in the females and sometimes wanting on the posterior pair), and the

fifth ventral segment slightly hollowed down the middle. ‘The deciduous portion of

the mandibles is broad, somewhat cultriform, and vertical (fig. 14 @).

This insect is more ovate than the allied forms, the sides of the prothorax (which

are margined at the base) forming a continuous outline with those of the elytra, the

acute hind angles of the former sometimes slightly projecting beyond the humeri.

The upper surface in the typical form (fig. 11) is asymmetrically variegate with black

and cinereous (or whitish) scales, the dark scales usually condensed on the disc of the

prothorax into two strongly sinuate or curved stripes (which enclose a cruciform or

transverse whitish patch), these markings being entirely obliterated in the cinereous

variety. The setze (often abraded) are so short and inconspicuous that they are hardly

visible till the insect is viewed in profile. The two specimens sent me for examination

by Dr. Sjéstedt differ greatly in size, and the long series received from Matamoros

varies in the same way. The immaculate variety is represented by five examples from

Colima City, two from the Sturm collection, and one in the British Museum.

2. Coleocerus virescens, sp. n. (Tab. XIV. figg. 12, 12a.)

Oblong-ovate, piceous, densely clothed with intermixed pale green and cinereous scales, those on the under

surface metallic, the elytra mottled with fuscous. Rostrum sulcate and deeply excavate. Antenne

rather slender, the joints of the funiculus becoming shorter and stouter outwards, 2 shorter than 1.

Prothorax strongly transverse, explanate and sharply margined at the sides posteriorly, obliquely

narrowed thence to the apex, and distinctly narrowed at the base, the base itself deeply bisinuate, the

hind angles acute; densely finely punctate. Scutellum broad, strongly transverse. LElytra oblong,

scarcely wider than the prothorax, punctate-striate, the interstices feebly convex. Mesosternal

One specimen, without definite locality. This is the only species of the genus

the Texan C. dispar (Lec.), which has the prothorax more feebly sinuate at the

base, &c.

3. Coleocerus denticollis, sp.n. (Tab. XIV. figg. 13, 13 a.)

Oblong-ovate, piceous; the prothorax and elytra densely clothed with brownish-cinereous, and the rest of

the surface with whitish or cinereous, scales. Rostrum sulcate and deeply excavate. Prothorax

strongly transverse, angularly dilated at the sides before the base and obliquely narrowing thence to the

apex, the sides margined posteriorly and emarginate between the angular dilatation and the sharp hind

angles, the base bisinuate ; densely, finely punctate. Scutellum transverse. Elytra not wider than the

prothorax, narrowing from the base, closely punctate-striate, the interstices feebly convex. Mesosternal

The numerous specimens referred to this species (the only one from Oaxaca to

which Boheman’s description is applicable) differ from C. setosws in having the

prothorax distinctly narrower than the elytra at the base, and the sides not or feebly

elytra into two oblique or transverse fascie on the outer part of the disc and various

asymmetrically distributed small scattered spots. The eight examples from Salina

Cruz (fig. 15), all of comparatively small size, are in beautifully fresh condition and

have the whitish markings very sharply defined. In two specimens (one from Tocoy

and one from San Andres Tuxtla) the cinereous vestiture predominates, and in one of

those from Juquila it is reduced, on the contrary, to a few small spots. An example

from Tehuantepec (nab, in U.S. Nat. Mus.) with the scales greenish-cinereous may

belong here. In many of them, including those from Salina Cruz, the posterior margin

of the buccal cavity is produced into a tooth-like projection at the middle in front,

just behind the mentum. The males have the prothorax more rounded at the sides

than the females.

Tamaulipas (Schwarz, in U.S. Nat. Mus.).

I have seen six specimens of this species from within our limits agreeing with others

before me from San Diego and Brownsville, Texas. The markings are variable, the

cinereous scales sometimes predominating, but the blackish scales are never condensed

into two uninterrupted broad vitte on the disc of the prothorax as is often the case in

C. variegatus, the latter also having the prothorax less distinctly narrowed at the base

than in C. marmoratus, at least in the female.

6. Coleocerus crassipes, sp. n.

Subovate, convex, black; variegated with a dense clothing of rather large, imbricate, pale brown, fuscous,

and whitish scales, the last-named condensed on the prothorax into a faint median line and a curved

submarginal stripe, and those on the elytra into two transverse patches or fascie on the outer part of

the disc and various irregular partly confluent smaller spots; the surface also set with minute, scattered,

curled, decumbent sete. Rostrum broad, depressed down the middle, and with a small bare fovea

behind the nasal plate. Prothorax transverse, much broader at the base than at the apex, the

hind angles subrectangular as seen from above and immarginate externally, the base bisinuate, the

surface densely punctate. Scutellum small, transverse. Elytra oblong, not or very little wider

than the prothorax; punctate-striate, the interstices feebly convex. Mesosternal protuberance small,

conical. Legs stout.

Six specimens. Extremely like C. rotundicollis, and only differing from it in the

much less rounded sides of the prothorax and the more oblong elytra. It is possible

they are the sexual complements of the same species, but this is not likely to be the

case. ‘The less excavate, non-sulcate rostrum and the feebly protuberant mesosternum

separate C. crassipes from all the varieties of C. variegatus and C. setosus.

two transverse patches on the outer part of the disc and various irregular more or less confluent smaller

spots, the scales on the under surface whitish; the surface also set with short, scattered, curled,

decumbent sete. liostrum broad, depressed down the middle, and with a small bare fovea behind the

nasal plate; joint 1 of the funiculus nearly twice as long as 2. Prothorax transverse, very little

narrower at the apex than at the base, the base itself bisinuate, the sides rounded from the obtuse hind

angles, the surface densely punctate. Scutellum small, transverse. Elytra convex, oval, the humeri

rounded; punctate-striate, the interstices feebly convex. Mesosternal protuberance small, subconical.

Hab. Mexico, Acapulco (Hége; Knab, in U.S, Nat. Mus.).

Seven examples, varying a little in the intensity of the markings. The rotundate,

Three species from Mexico or Guatemala differ in the above-mentioned characters

from Coleocerus and they must be separated from that genus. ‘The scrobes in both

genera are continued beneath the eyes and become coalescent on the under surface,

this character separating Ewcoleocerus and Coleocerus from Promecops.

two brownish or fuscous spots or interrupted vittse on the disc, and the elytra confluently, asymmetrically,

fusco-variegate; the surface also set with scatterel very short, curled, adpressed setee, the ventral

segments with intermixed suberect white hairs. Rostrum subquadrate, slightly hollowed down the

middle anteriorly, and with a bare fovea behind the rather long, narrow, triangular nasal plate ; joints

1 and 2 of the funiculus subequal in length. Prothorax transverse, rapidly, obliquely narrowed from

species differs from the maculate form of H. conicicollis in having the prothorax less

widened towards the base and sharply fusco-vittate on the disc; the elytra more

elongate, more developed inferiorly below the humeri, and with the lower margin

strongly sinuate; and the first ventral segment more broadly excavate, and the fifth

Lacordaire, Gen. Col. vi. pp. 385, 389.

A genus including a large number of closely allied Tropical American forms, several

of which are so imperfectly characterized that they are not recognizable from the

descriptions alone. Lacordaire has called attention to the fact that the species are

divisible into two groups, one with connate and the other with free tarsal claws ; he

restricts Promecops (in his table of the genera of Promécopides) for the former.

Some of the members, again, of the second group have the mesosternum conically

protuberant as in Coleocerus (P. lepida, leucothyrea, rhombica, rhombifera, unidentata,

&ce.); others (P. viator, umbrata, and several of the new forms here added) have the

mesosternum flattened or simply convex. It is preferable to leave them all under one

genus, Promecops, for the present, the species being often so much alike that they are

only separable by the structure of the claws or mesosternum. In some of the new

forms now added remarkable characters are to be found in the anterior tarsi or anterior

tibie of the males. The various species, many of which are very variable in size and

colour *, may be tabulated thus :—

* The extent of variation is well shown in a series of about 450 examples of P. lunata, Fahr., obtained by

Mr. H. H. Smith in the Windward Is. (St. Vincent, Grenada, Becquia, and Cannouan). This species has

small, connate tarsal claws and a simply convex mesosternum.

‘arina or groove down the posterior half of the disc. The specimens standing under

P. umbrata in the Sallé collection and in the British Museum belong to P. viator,

The numerous individuals referred to P. wumbrata (the type of which cannot now be

found in the Stockholm Museum) merely differ from P. viator in having the elytral

setee less numerous, short, curled, and decumbent, but often becoming longer and

more erect towards the base. A long series from Atoyac agree in this respect, and I

have therefore retained the two forms as distinct. The Mexican insect referred by

Fahreus to P. nubifer, Gyll., probably belongs here *.

oblique transverse fasciz (one before the middle, the other subapical) on each elytron, the blackish

scales clustered into a common transverse patch at the kase and a large patch on each between the

pallid fascie (these markings being sometimes coalescent along the suture); the surface also set with

scattered, curled, decumbent seta, those on the elytra seriately arranged down each interstice. Rostrum

Prothorax transverse, rather convex, rounded at the sides, constricted and narrowed in front, finely

canaliculate or subcarinate down the middle from near the apex to the base, the surface with rather

coarse scattered punctures. Elytra oblong, very gradually narrowing from the prominent humeri, much

wider than the prothorax; punctate-striate, the interstices convex. Mesosternum protuberant. Legs

stout; all the tibie strongly unguiculate, the anterior and intermediate pairs serrulate, the anterior

pair armed with a long, acute, oblique tooth on the inner edge near the apex (fig. 22 6), the inter-

mediate pair abruptly excavate near the tip, the excavation preceded by a sharp tooth; tarsal claws

long, free.

Q. Elytra subparallel in their basal half; anterior tibise without subapical tooth, the intermediate pair simply

hollowed at the apex within, the uncus of cach less bowed inwards and not so stout.

Length 4-6, breadth 13-23 millim. (¢ ¢.) .

Hab. ?Costa Rica (Mus. Brit.: 9); Panama, Bugaba, Volcan de Chiriqui, David,

Numerous examples, females preponderating. Lasily distinguishable from the

allied forms by the structure of the anterior and intermediate tibie of the male,

* P. nubifer was said by Gyllenhal (Schénh., Gen. Cure. ii. p. 167) to be from “ North America”; Fabreeus

Promecops leucothyreus, Fahy. in Schénh. Gen. Cure. vi. 1, p. 328°.

Promecops quadrimaculatus, Jekel, in Mus_ Brit.’.

Oblong, robust, piceous; variegated with a dense clothing of cinereous, brown, and blackish scales, the

last-named usually clustered into two broad vittz on the dise of the prothorax (sometimes more

extended and coalescent, leaving only a basally abbreviated median line and two short streaks on each

side cinereous), the cinereous scales on the elytra condensed into an interrupted oblique or transverse

fascia before the middle and another near the apex; the scales at the apex of the rostrum, on the

scutellum, humeri, elytral fascize, base of the femora, and tarsi often more or less green, those on

the under surface varying in colour from cinereous to green; the upper surface also set with very

short, scattered, curled, decumbent sete. Head and rostrum densely punctate, the vertex with a

transverse raised line separating the exposed portion from that covered by the prothorax, the rostrum

moderately broad, canaliculate; eyes strongly transverse, narrow; joint 2 of the funiculus slightly

shorter than 1. Prothorax transverse, convex, obsoletely canaliculate, rounded at the sides, the latter

parallel at the base; with coarse punctures intermixed with a dense fine punctuation. Elytra

subparallel in their basal half, rather convex, punctate-striate, the interstices feebly convex. Meso-

sternum protuberant. Legs stout; all the tibiew strongly unguiculate in g, more feebly so in Q ;

tarsal claws long, free.

Length 43-6, breadth 2-22 millim. (¢ ?.)

Hab. Mexico (Hége, in coll. Solari), Tampico (Schwarz, in US. Nat. Mus.), Salina

Cruz (Knab, in U.S. Nat. Mus.), El Camaron (Sallé), Tapachula (Hége) ; Guatemata,

Volcan de Atitlan (Champion); Satvapor, Sonsonate, Acajutla (Hnab, in U.S. Nat.

Mus.) ; Nicaragua, Granada (Sallé).—Cotomaia (Mus. Brit.), Bogota !, Carthagena 2.

I have seen seventeen specimens of this species, including the type and two others

from Colombia in the British Museum. It is extremely variable in regard to the

markings of the upper surface, according to the predominance of the dark or light

scales, and the elytral fasciz are often broken up into spots, which are sometimes

green. The Tampico example is like the type. TheSalina Cruz specimen (9)

(fig. 24) and one of those from Colombia are cinereous variegated with fuscous.

The Mexican male figured (fig. 23) has been lent me by Signor A. Solari.

5. Promecops dentimanus, sp. n. (Tab. XIV. figg. 25, 25a, ¢.)

Oblong, robust, piceous; variegated with a dense clothing of brown, blackish, and cincreous scales, the

blackish scales on the prothorax clustered into a curved line on each side of the disc and those on

the elytra into a common, broad, irregular, post-median fascia, which extends up the suture to the base

and is limited anteriorly by a transverse row of confluent cinereous spots ; the elytra also set with long,

scattered, suberect sete along each interstice, the rest of the surface with short, curled, decumbent,

bristly hairs. Rostrum broad, somewhat concave, canaliculate, densely punctate; eyes strongly

transverse, narrow ; antenne comparatively short, the scape much widened towards the tip, joint 2 of

the funiculus shorter than 1, 5-7 transverse. Prothorax transverse, obliquely narrowed towards the

base and apex, as wide in front as behind, finely punctate, carinate or obsoletely canaliculate down the

middle from near the apex to the base. Elytra oblong-subtriangular, punctate-striate, the interstices

feebly convex. Mesosternum not protuberant.. Legs stout; all the tibie strongly unguiculate in both

sexes, the intermediate pair hollowed near the apex within in g, more feebly so in Q ; anterior

tarsi (fig. 25) with a stout dentiform process on the upper surface of the inner portion of the bilobed

third joint in ¢ ; tarsal claws free.

Length 44-54, breadth 12-21 millim. (¢ 9.)

Hab. Panama, Caldera and David in Chiriqui (Champion).

Two males and two females, the single example from David being a very large

female with the rostrum concave above. The toothed inner lobe of the third joint

of the anterior tarsi of the male is a remarkable character. The female is very like

that of P. wnidentata, from which it may be known by its shorter antenne, the

broader rostrum, the less convex, more finely punctured prothorax, which is as wide

at the apex as at the base, the suberect long elytral sete, and the non-protuberant

mesosternum.

6. Promecops tridentata, sp. n. (Tab. XIV. figg. 26, 26a, ¢.)

Oblong, robust, piceous ; variegated with a dense clothing of cinereous, brown, and blackish scales, the

cinereous scales condensed into a curved stripe on each side of the prothorax, a spot on the scutellum,

and two curved transverse fascize on each elytron (one, before the middle, sometimes interrupted, not

reaching the suture, widening outwards, and connected exteriorly with a transverse humeral patch, the

other subapical) ; the elytra also set with long, suberect, rigid setee down each interstice, and the rest of

the upper surface with short, curled, decumbent, bristly hairs; the legs annulate, the scales on the under

surface of the body uniformly cinereous. Rostrum broad, depressed, and canaliculate down the middle;

joints 1 and 2 of the funiculus subequal in length. Prothorax strongly transverse, rounded at

the sides, slightly constricted in front, finely carinate or obsoletely canaliculate down the middle from

near the apex to the base, the surface finely, closely punctate. LElytra oblong-subtriangular in <,

subparallel in their basal half in 9, punctate-striate, the interstices feebly convex. Mesosternum

simple. Legs stout; all the tibia strongly unguiculate, the anterior pair in ¢ (fig. 26a) armed on

the inner edge with three long, projecting, truncated or slightly hooked teeth, and usually with a

smaller additional tooth near the tip, in 2 with three small teeth only; tarsal claws free.

Length 32-6, breadth 14-23 millim. (d 9.)

Hab. Guatemata (Mus. Brit.), Capetillo, Zapote (Champion).

Numerous examples, the sexes about equal in number. The three long, projecting,

more or less hooked teeth on the anterior tibiee of the male characterize this species,

a female of which was acquired by the British Museum in 1855.

7. Promecops clavisetis, sp.n. (Tab. XIV. figg. 27, 274, 2.)

Oblong, convex, robust, piceous; variegated with a dense clothing of blackish, brown, and cinereous scales,

the darker scales on the elytra condensed into a broad post-median fascia, and the cinereous scales into

an irregular fascia below the base and a narrower and straighter one towards the apex ; the alternate

elytral interstices also set with scattered, stout, clubbed, setiform, light and dark scales, and the rest

of the surface with short, curled, decumbent sete. Rostrum broad, canaliculate; joint 2 of the

funiculus longer than 1, Prothorax convex, transverse, rounded at the sides, closely punctate. Elytra

subparallel in their basal half, somewhat gibbous, transversely depressed below the base; punctate-

striate, the alternate interstices raised, the others feebly convex. Mesosternum not protuberant. Legs

very stout; the tibiz feebly unguiculate; tarsal claws free.

gibbous, cinereo-bifasciate elytra, the alternate interstices of which are raised and set

with short, stout, clubbed, light and dark, setiform scales. The tibial claw is feebly

developed, and the specimen therefore (its very stout legs notwithstanding) is probably

a female. P. cincta, F&hr., from Brazil, must be an allied form.

8. Promecops alternans, sp.n. (Tab. XIV. fig. 28, ¢.)

Oblong, piceous or obscure ferruginous; variegated with a dense clothing of cinereous, brown, and blackish

scales, the cinereous scales on the prothorax condensed into three vitte (the median stripe sometimes

wanting) and those on the elytra into two oblique fascie, which are sometimes broken up into spots ;

the elytra also set with scattered, rather long, curled, semierect setw, which (except on the apical

declivity) are mostly confined to the alternate interstices, the rest of the upper surface with short,

curled, decumbent hairs, the scales on the under surface cinereous. Rostrum broad, hollowed and

eanaliculate ; joint 2 of the funiculus shorter than 1; eyes large, transverse. Prothorax broader than

long, obliquely narrowed in front and behind, closely punctate. Elytra convex, oblong-subtriangular

in ¢, subparallel in their basal half in Q ; punctate-striate, the interstices feebly convex. Mesosternum

not protuberant. All the tibie unguiculate in both sexes, the anterior pair without teeth; tarsal claws

small, free.

Length 4-53, breadth 12-23 millim. (¢ @.)

Hab. British Honpuras, Rio Hondo (Blancaneaux) ; GuateMAta, Teleman and San

Juan in the Polochic Valley (Champion).

Eleven specimens, all but two from Guatemala. This insect differs from most of

the similarly-coloured forms in having the long, scattered sete on the basal half of the

elytra confined to the alternate interstices. The male is robust and oblong, resembling

P. dentimanus in shape.

9. Promecops brevisetis, sp. n. (Tab. XIV. fig. 29.)

Oblong, subovate, piceous or obscure ferruginous; variegated with a dense clothing of cinereous, brown,

and blackish scales, the cinereous scales condensed on the prothorax into a sinuous vitta on each side

(sometimes extending inwards and leaving only a narrow brown median stripe) and those on the elytra

into two oblique fascie (the anterior one not reaching the suture) and various small scattered spots ;

the upper surface also somewhat closely set with short, curved, decumbent set, those on the elytra

seriately arranged down each interstice, the scales on the lower surface cinereous. Rostrum broad,

hollowed and canaliculate ; joint 2 of the funiculus shorter than 1. Prothorax transverse, somewhat

angularly dilated at the sides just beyond the middle, about equal in width at the base and apex;

closely, finely punctate, and finely carinate or obsoletely canaliculate down the middle of the posterior

half. Elytra convex, punctate-striate, the interstices raised. Mesosternum simpie. Anterior tibice

without teeth. Tarsal claws free.

Length 24-5, breadth 14-2} millim.

Hab. Muxico, Tampico in Tamaulipas (Schwarz, in U.S. Nat. Mus.), San Rafael

Jicaltepec (Zownsend, in U.S. Nat. Mus.) ; Guatemata, Las Mercedes, Pacific slope

(Champion).

Two specimens from Guatemala (taken as the types) and a series from each of the

Mexican localities. ‘This insect is so like P. wmbrata that it can only be separated

therefrom by the free tarsal claws; and the very short curved sete along each elytral

interstice distinguish P. brevisetis from P. alternans. The sexes are scarcely

: distinguishable by external characters.

10. Promecops uniformis, sp. n. (Tab. XIV. fig. 30, 3.)

Oblong, robust, piceous; densely, uniformly clothed with brown or greyish-brown scales, the elytra sometimes

with a faint, darker, interrupted, transverse fascia beyond the middle, the surface also set with rather

long, scattered, decumbent sete, those on the elytra seriately arranged down each interstice ; the scales

on the under surface cinereous or greenish-cinereous. Rostrum broad, slightly hollowed, and canaii-

culate; joint 2 of the funiculus a little longer than 1; eyes large, transverse, oval. Prothorax

transverse, obliquely narrowed towards the base and apex, about as wide in front as behind, closely,

finely punctate. Elytra oblong-subtriangular in ¢, subparallel or slightly widened to the middle in °,

punctate-striate, the interstices feebly convex. Metasternum and first ventral segment broadly hollowed

down the middle in ¢. Mesosternum simple. Legs very stout in ¢, more slender in 2, the tibie

moderately unguiculate in the two sexes; tarsal claws long, free.

Length 5-64, breadth 2;-23 millim. (¢ Q.)

Hab. Guatemata, Capetillo, Duefias, Cerro Zunil (Champion), Chimaltenango

(Conradt).

Seven males and four females. In this insect there is no trace of the usual pallid

elytral fascie, but there is sometimes an interrupted, blackish, somewhat denuded band

visible beyond the middle, especially in the female. The males sometimes have the

legs excessively stout. ‘The tarsal claws are long, as in P. wnidentata.

SUPPLEMENT

TO THE

THECESTERNINE AND OTIORHYNCHINA®*,

‘Tuts Supplement to the subfamilies Thecesternine and Otiorhynchine 7 includes the

additional material received since 1891, a few species left by Dr. Sharp for further

study, and some other forms that had been overlooked in our own or in the British

Museum collections. A few corrections in the synonymy have become necessary,

mainly owing to the discovery of various Mexican types in the “ Sommer ”’ collection,

kindly lent by Mr. O. E. Janson and Prof. Poulton.

* By G. C. Coamrion.

+ The Supplementary Apionine have been handed over to the specialist Herr Hans Wagner for deter-

mination, and his descriptions of the new forms will be published elsewhere. The specific names of three

species of the genus Apion described in the present Volume were preoccupied, and they have been changed

by Wagner (Deutsche ent. Zeitschr. 1909, p. 766) thus: longimanum, Sharp (nec Rey) (p. 62)—macropus ;

longicolle, Sharp (nec Gerst.) (p. 80)—macrothorax ; gibbeswm, Sharp (nec Herbst) (p.82)—peculiare. Of the

three other subfamilies dealt with by Dr. Sharp, the Attelabine, Pterocoline, and Allocoryninze, but little has

since come to hand, and no Supplement is therefore required. It may be observed, however, that a species of

the genus Allocorynus (A. slossont, Schaeff.) has recently been described from the United States.

Thecesternus humeralis (p. 86).

Mr. Pierce, in his recent revision of this genus [Proc. U.S. Nat. Mus. xxxvii.

pp. 334-339 (1909)], recognizes several of Leconte’s species (previously sunk as

synonyms of 7 humeralis) as distinct, and describes four others as new. The two

specimens from Tamaulipas referred by Dr. Sharp to 7. humeralis, and another since

received from Sabinas in Nuevo Leon (Flohr), seem to belong to T. affinis, Lec.

We are indebted to Mr. Wickham for a series of 7. humeralis, Say, from Cafion City,

Colorado, and to the U.S. Nat. Museum for co-types of 7. maculosus, albidus, and foveo-

latus, Pierce. T. affinis differs from 7. humeralis in having less prominent humeri and

the elytra more rounded at the sides, in this respect approaching 7’. maculosus.

from Texas and New Mexico (a specimen of which, from San Diego, is now before me)

under the above name is O. ovipennis, Sharp. 0. tuberosus, Lec., from New Mexico,

may be known from 0. bitubercsus by the feebly, transversely depressed base of the

rostrum, and the rather more convex, oval elytra, without trace of humeri.

4 (a). Ophryastes tetralobus, sp.n. (Tab. XV. figg. 1, 1a.)

Moderately elongate, black, clothed with intermixed whitish and fuscous scales, and also set with minute,

scattered, short, decumbent hairs. Rostrum very broad, faintly transversely depressed at the base,

deeply trisulcate, the sulci separated by two posteriorly converging ridges, the median groove extending

backward along the flattened, laterally sulcate, inter-ocular portion of the head, the lateral grooves also

long. Prothorax strongly transverse, laterally bilobato-dilatate, constricted just before the base, the

groove in front of the basal ridge deeply impressed laterally, obsolete in the centre, the depressed narrow

basal portion feebly produced in the middle behind; the surface obliquely wrinkled and sparsely, coarsely

punctate, Elytra moderately convex, oblong-oval, not wider than the dilated portion of the prothorax,

with a short, abrupt, neck-like constriction at the base; coarsely punctate-striate, the interstices

convex.

clothed with adhesive pubescence beneath [¢f. Fall, Trans. Am. Ent. Soc. xxxvi. p. 189 (1910)]. A specimen

of it from Arizona has been sent me by the U.S. Nat. Museum (det. Pierce) as HZ. argentatus, Lec.

RHYNCHOPHORA: OTIORHYNCHINE. 319

One worn example, probably a male. Very like 0. dituberosus, but with a short

neck-like constriction to the elytra at the base (somewhat as in Kupagoderes constrictus),

the frons and rostrum deeply trisulcate, and the inter-ocular portion of the head

flattened. ‘The sides of the prothorax are explanate and strongly bilobate. Fresh

specimens would doubtless be more definitely albo-squamose.

4 (z). Ophryastes collaris, sp.n. (Tab. XV. figg. 2, 2, ¢; 3,34, 2.)

Moderately elongate, black; densely clothed with chalky-white or pale brownish scales, the head with a small

patch on each side above the eyes, the prothorax with three spots at the apex, and the elytra with

various irregular scattered patches, infuscate, the intermediate and posterior femora also fusco-annulate

in front; the surface also set with minute, short, scattered hairs. Rostrum very broad, without definite

transverse depression at the base, deeply trisulcate, the lateral grooves converging posteriorly, the

flattened inter-ocular portion of the head also shallowly trisulcate. Prothorax strongly transverse,

laterally bilobato-dilatate (the posterior lobe prominent and the prothorax here nearly or quite as wide

as the elytra), constricted just before the base, the groove in front of the basal ridge deeply impressed

laterally and obsolete in the middle, the depressed narrow basal portion angularly produced backwards

in the middle; the surface uneven, sparsely, coarsely punctate. Elytra convex, oblong-oval, with a short

neck-like constriction at the base; coarsely punctate-striate, the interstices convex.

Two specimens, assumed to be male and female, the Texan example (2) being

much broader than the other. Near 0. tetralobus, but with the median groove of the

rostrum obsoletely extending on to the inter-ocular portion of the head, the latero-

anterior lobe of the prothorax less prominent, and the depressed basal portion of the

prothorax more produced in the middle behind. The neck-like constriction to the base

of the elytra separates O. collaris from O. tuberosus, bituberosus, and basalis, the last-

mentioned insect, moreover, having the median sulcus of the rostrum extending

upwards. ‘The dark markings may be partly due to abrasion or discoloration. Both

examples are figured.

Mr. Pierce [Proc. U.S. Nat. Mus. xxxviil. pp. 344, 345 (1909)] has recently added

two species to this genus, from ‘l'exas and New Mexico respectively, and another from

Coahuila has recently been sent us by the U.S. Nat. Mus., to whom we are also

indebted for co-types of the N.-American forms.

Oblong-ovate (3), subovate (@ ), black, densely clothed with small, imbricate, chalky-white scales, and also

set with very short, curled, decumbent, scattered, setiform hairs. Rostrum very stout, transversely

depressed at the base (arcuate above, as seen in profile), trisulcate, the sulci separated by two posteriorly

converging ridges. Prothorax strongly transverse, uneven, sparsely, coarsely punctate; the sides dilated

at about the middle, crenate, and deeply, abruptly constricted just before the base; the ocular lobes

prominent, the vibrisse short. Elytra oval, broader and less constricted at the base in the @ than in

EUPAGODERES (p. 93).

The N.-American species of this genus, two at least of which extend southward into

our region, have been recently revised by Mr. Fall [Trans. Am. Ent. Soc. xxxvi.

pp. 189-194 (1910)]. Eleven were recorded by Dr. Sharp from Mexico, and three

others are now added. The following additional localities may be noted for the known

Mexican forms: E. mexicanus—Mescala in Guerrero (H. H. Smith); E. cinereus—

Saltillo in Coahuila and Durango * (Wickham); E. squalidus—Durango (Wickham),

also found by Truqui; L. cretaceus (t= sordidus, Lec.)—Arizona (Linell, ea U.S. Nat.

(tin Morelos) (ex coll. Flohr), Mescala (H. H. Smith).

1 (a). Kupagoderes rotundatus, sp.n. (Tab. XV. figg. 5, 5a.)

Obovate, black, thinly squamose above, the scales pale brown on the elytra and whitish on the rest of the

surface, the intermixed scattered seta minute and extremely short. Rostrum transversely depressed at

the base, trisulcate, the lateral sulci deep and rather short; head flattened between the eyes; joint 2

of the funiculus a little longer than 3. Prothorax strongly transverse, feebly rounded at the sides,

slightly broader at the base than at the apex, the basal and apical grooves deeply impressed laterally,

the apical groove obsolete on the disc, the vibrissw rather short; the surface impressed with coarse

scattered punctures, and interruptedly sulcate down the middle. Elytra very convex, broad, rotundate-

ovate, widest at the middle, acuminate at the tip; rather coarsely punctate-striate, the interstices

moderately convex. Anterior tibiz obsoletely denticulate. Tarsal joints 1-3 with a patch of adhesive

pubescence on each side beneath.

was captured on July 4th. Near LH. constrictus, Sharp, from San Isidro t, but wanting

the neck-like constriction at the base of the elytra (the elytra being rounded from the

base and without trace of subhumeral prominence in the present species); the prothorax

‘Two specimens, one (the type) labelled as having been captured at Lampazos in 1890,

the other (numbered 93) presumably from the same locality, the latter being retained

for the British Museum. In Mr. Fall’s Table of the N.-American species [Trans.

Am. Ent. Soc. xxxvi. pp. 193, 194 (1910)], #. turbinatus comes near EF. dunnianus,

Casey, and H. decipiens, Lec., from both of which, and from the allied EL. duranqoensis,

Sharp, also, it may be distinguished by the anteriorly widened prothorax. ‘The elytra

are maculate as in the last-mentioned insects.

Eupagoderes cretaceus (p. 96).

‘wo specimens ofa Hupagoderes have been sent us under the name /. sordidus,

Lec. (det. Pierce), by the U.S. Nat. Museum: one of these, from Arizona, does not

differ from E. cretaceus, Sharp; the other, from San Bernardino, California, is probably

a form of E. aridus, Fall. If the Arizona insect is correctly named, the name

FE. cretaceus, Sharp (the types of which are from Villa Lerdo in Durango), will fall as

a synonym of HL. sordidus.

12. Eupagoderes depressirostris, sp. n.

Obovate, black, clothed with intermixed brownish-cinereous and white scales, and also set with fine scattered

sete, which become longer, suberect, and more crowded on the apical declivity. Itostrum flattened and

somewhat abruptly separated from the head, without trace of median groove, the oblique lateral sulci

faintly indicated ; joint 2 of the funiculus about half the length of 3. Prothorax strongly transverse,

comparatively small, somewhat rounded at the sides, feebly constricted just betore the base, the basal

groove almost obsolete on the disc, the vibrisse extremely short; sparsely, coarsely punctate and

obsoletely canaliculate. Elytra convex, rotundate-ovate, abruptly declivous behind, the apices obtuse ;

One specimen, somewhat abraded, and for that reason left unnamed by Dr. Sharp.

This species approaches EL. gracilis*, but it has the elytra almost as globose as in

* Additional specimens of Z. gracilis have been received from Matamoros Izucar and Tlaltizapan (Flohr),

some of these showing a distimet narrow median sulcus on the rostrum.

E. rotundatus. The rostrum is flattened and without trace of median sulcus, the

prothorax very short, the elytra closely setose on the apical declivity, and the legs

rather slender.

AMPHIDEES (p. 97).

The additional material of this genus now to hand includes various specimens of

A. macer from Tres Marias in Morelos (Wickham) and others collected by ‘Truqui.

Deamphus puncticollis (antea, p. 104), of which a second example has been found

amongst Truqui’s captures, is so nearly related to A. macer that it must be included

in the same genus, the ocular lobes (and conspicuous vibrisse) being as distinctly

traceable as they are in A. pilosus. JD. latifrons also has rather long vibrisse and

sufficient sinuation of the anterior margin of the prothorax to indicate a rudimentary

ocular lobe; it would therefore be better placed in Amphidees, near A. macer and

A. puncticollis. In the two other species referted to Deamphus—D. brevipennis (type

of genus) and D. deceptor—the vibrisse are altogether wanting and there is no trace

of an ocular lobe.

6 (a). Amphidees acuminatus, sp.n. (Tab. XV. figg. 7, 7 @.)

Oblong-ovate, acuminate, piceous, the antenne and tarsi obscure ferruginous; thickly clothed with cupreo-

cinereous and brownish scales, the elytra indefinitely fusco-variegate, the surface also set with long

scattered, suberect, stout setee. Rostrum short, stout, depressed at the base, shallowly bisuleate on each

side of the somewhat raised median portion, the inter-ocular portion of the head flattened. Prothorax

transverse, subtruncate at the base, with feebly developed ocular lobes ; impressed with scattered, rather

coarse, confluent punctures intermixed with a close fine interstitial punctuation, and also canaliculate

down the middle. Elytra acuminate-ovate, constricted immediately below the base, the humeri thus

appearing prominent, the base itself truncate; with rows of scattered moderately coarse punctures, the

interstices flat on the disc, becoming feebly convex outwards. Second ventral segment at the middle

nearly as long as the next two united.

Length 74, breadth 3 millim. (2?)

Hab. Mexico (Truqut).

One specimen. Distinguishable by the short, basally depressed, feebly quadrisulcate

rostrum, and the acuminate, basally constricted, strongly setose elytra. ‘The scrobes

are less extended backward and the humeri more prominent than in the allied

A, alternans, Sharp.

SYNOSOMUS (to follow the genus Amphidees, p. 101).

Synosomus, Jekel, Ann, Nat. Hist. (3) i. p. 858 (1858).

The type of this genus * (unlike those of the other forms described by Jekel in the

same paper) cannot now be found in the British Museum. The presence of ocular

‘lobes to the prothorax, the posteriorly widened, evanescent scrobes, the absence of

scutellum, the exhumerate elytra, &c., seem to bring Synosomus near the Mexican

genus Amphidees.

Epiczrus niger (p. 106).

The types of this species were from Orizaba: the male is narrower and more elongate

Epicerus nebulosus (p. 111).

? Epicerus neglectus, Boh. in Schénh. Gen, Cure, ii. p. 825°.

We have now seen a long series of this species and there can be little doubt that

it was correctly identified by Dr. Sharp, the convex, prominent eyes and the subcon-

stricted head separating EF. nebulosus from both £. mexicanus and LE. fallax. ‘The type

of E. neglectus (an insect omitted from the list of species, anted, pp. 105-128), also from

Mexico 2, cannot now be found in the Hope collection at Oxford: it is probably a

female of EF. nebulosus. The British Museum has recently received examples of the

latter from Vera Cruz which were captured by Mr. Crawford.

15 (a). Epicwrus macropus, sp. n. (Tab. XV. figg. 8, 8a, 3.)

Very elongate, narrow (d), broader (¥ ), black; thickly clothed with coppery-brown scales, the scales often

becoming cinereous towards the sides of the elytra, at the base of the femora, and on part of the body

beneath, the surface also set with short, decumbent, intermixed sete, which become more conspicuous

on the apical declivity. Rostrum stout, a little longer than the head with the eyes, broadly hollowed

down the middle, canaliculate from the small inter-ocular fovea, finely punctate, the eyes large, oval,

depressed ; antenne slender, joint 2 of the funiculus much longerthan 1. Prothorax longer than broad,

obliquely narrowed anteriorly and subcylindrical in ¢, gradually narrowing forwards in 9, truncate

at the base ; irregularly, confluently foveolate and with a fine interstitial punctuation, the dise obsoletely

suleate down the middle. Elytra elongate, not or very little wider than the prothorax in g, broader

in 2, constricted at the base, the apical declivity (viewed in profile) rounded in both sexes, the humeri

rather prominent; with rows of moderately coarse scattered punctures, the interstices transversely

wrinkled. Legs very elongate; anterior tibie obsoletely denticulate.

Length 123-153, breadth 33-5 millim. (¢ Q.)

Hab. Mexico, “ Sierra de Durango” (fége).

Five males and one female. An elongate form nearly related to L. cultripennis, but

differing from it in the simply rounded (not abruptly perpendicular) apical declivity of

the elytra, this being particularly noticeable in the female (cf. Tab. V. figg. 3 a, 4¢).

Epicerus reversus (p. 113).

To the Mexican localities given, add :—Oaxaca (Mus. Brit.), Chiapas (coll. Fry).

The types (¢ 2) were from San Andres Tuxtla in Vera Cruz, the female, as usual,

being much broader than the male.

21 (a). Epicerus macropterus, sp.n. (Tab. XV. fig. 9, ¢.)

Very elongate, narrow, black; thickly clothed with greyish-brown scales, which become paler and somewhat

eupreous on the under surface, the elytra also set with very short, scattered, curled, decumbent sete.

Rostrum longer than broad, deeply sulcate down the middle, tne sulcus narrowing upwards and nearly

reaching the conspicuous inter-ocular fovea, and also with a shallow groove on each side before the eyes,

the latter large and moderately prominent. Prothorax about as long as broad, truncate at the base,

somewhat rounded at the sides, the latter obliquely converging anteriorly and abruptly constricted before

the hind angles ; shallowly sulcate down the middle, transversely confluently foveolate, and also closely,

finely punctate. Elytra very elongate, at the basal third slightly wider than the prothorax, constricted

just behind the prominent humeri, convex on the apical declivity; the seriate punctures fine and

scattered, the interstices feebly transversely undulate. Anterior tibia with several short setigerous

denticles scattered along their inner edge.

Length 103, breadth nearly 3 millim, (<¢.)

Hab. Mexico, Zacualtipan in Hidalgo (/ége).

One specimen, labelled by Dr. Sharp “ sp. n. near championi,” from which it differs

in its much more elongate shape, longer rostrum, obsoletely denticulate anterior tibie,

transversely rugose prothorax, and less undulate elytra. Seventeen specimens of the

Guatemalan insect were captured and there is nothing intermediate. ‘he small

denticles on the anterior tibie are wanting in the latter.

21 (s). Epicerus depilis.

Epicerus depilis, Boh. in Schéuh. Gen. Cure. vi. 2, p. 279°.

Very like H. macropterus, but with the rostrum shorter (not longer than the exposed portion of the head)

and more narrowly sulcate; the antennee shorter and stouter, with the outer joints of the funiculus as

broad as long; the prothorax less rugose, the coarse punctures mostly separate one from another: the

elytra more convex at the base, rounded on the apical declivity, the humeri not prominent, the seriate

punctures very coarse and deep.

Hab. Mexico (coll. Sommer '),

Fi. depilis was sunk as a synonym of H. cultripennis by Dr. Sharp (antea, p. 111),

but an inspection of the abraded type shows that this is not the case. It is just

possible that £. macropterus may prove to be the male of the same species.

Epicerus capetillensis (p. 115).

To the localities given, add :—Britisn Honpuras, Rio Sarstoon (Blancaneaur).

Epicerus griseus (p. 117).

Iam unable to distinguish . sphwroides from E. griseus, Boh., doubtfully retained

as distinct by Dr. Sharp, and the two forms would be better treated as one, for which

the name griseus should be used.

Epicerus monclove (p. 118). (Tab. XV. figg. 10, 104, ¢.)

The type of this insect (length 7, breadth 351; mm.) is a large, almost immaculate

female. ‘The male is smaller, narrower, and so distinctly maculate that I should have

hesitated to treat it as the sexual complement of the same species, were it not from

the same locality, Monclova in Coahuila. It may be described thus :—

do. Oblong, densely albo-squamose ; the prothorax with two very broad greyish-brown vitte on the disc

(leaving a submarginal line on each side and a narrow median stripe white), the elytra also greyish-

brown, with the following white markings :—a transverse patch at the base, an oblique fascia on the

outer part of the disc before the middle, extending forwards along the margin to the shoulder, a trans-

verse interrupted subapical fascia (formed by two subconfluent spots), and a common apical patch.

Epicerus durangoensis (p. 119).

This insect was described from four good specimens from Durango city. Mr. Wickham

has sent us two somewhat worn females from Tepehuanes, Durango, that seem to

belong to the same species :—

Var.? Prothorax densely clothed above with brown scales, a cruciform patch on the disc and a stripe on each

flank white, the elytra obsoletely, interruptediy fasciate with brown, the scales on the rest of the surface

whitish ; the rostrum somewhat deeply furrowed; the prothorax (as seen with the vestiture intact)

comparatively smooth, the intermixed coarser punctures inconspicuous; the elytral interstices flat, the

seriate punctures appearing fine till the scales are removed.

32 (a). Epicerus elegantulus, sp.n. (Tab. XV. figg. 11, lla, ¢.)

Epicerus elegantulus, Dupont, in litt.

Pyriform, convex, black; variegated with a dense clothing of whitish, pale brown, and fuscous scales, the

brown scales on the prothorax more or less condensed into a broad space on each side of the disc (leaving

a cruciform median vitta and a stripe along each flank white); the elytra with some irregular spots at

the base, two angulate common fasciz (the anterior one extending forward along the outer margin to the

shoulder, and both sometimes broken up into spots), and a patch at the apex, white, these markings

usually edged with fuscous (thus appearing very sharply defined); the femora in some examples fusco-

maculate beneath. Rostrum subquadrate, not longer than broad, grooved down the middle, the

inter-ocular portion of the head flattened, the eyes convex and prominent, especially in ¢. Prothorax

slightly broader than long, somewhat rounded at the sides in g, gradually narrowing from the base

in 9, the anterior margin sinuate; finely punctate and feebly canaliculate. Llytra at the base a little

wider than the prothorax, acuminate at the tip; the seriate punctures showing conspicuously through

the dense vestiture, the interstices almost flat. Legs short.

Epicerus decoratus (p. 121).

The types (¢ 2) of this species are worn, one only of them showing the oblique

whitish post-median fascia on the elytra. ‘There isa specimen in much better condition

in the British Museum. ‘This insect, a large female, is more rugose than the type ( ¢ ),

the seriate punctures on the elytra are each placed in a shallow, subquadrate fovea,

the depressed portions of the surface are clothed with intermixed white and greenish

scales, and the oblique sinuous fascia is not widened towards the suture. It is labelled

‘“* Mexico.”

Epicerus squamosus (p. 122).

It may be noted that the apical declivity of the elytra in this species is rounded in

the male and abruptly perpendicular in the female.

Epicerus marginatus (p. 122).

There can be little doubt that 4, insolitus (antea, p. 125) is the female of E. maryi-

natus, the type of which is a male. ‘They each have the anterior tibiz armed with

three or four conspicuous teeth along their inner edge. ‘The localities Pachuca (¢ )

and Zacualtipan ( 2 ) are not very far distant, and both in Hidalgo.

40 (a). Epiczerus truquianus, sp. n.

Oblong, narrow and convex ( ¢ ), much broader (Q ), black; above sparsely clothed with blackish scales, which

become cinereous towards the sides and apex, and are here intermixed with short, scattered, decumbent,

whitish sete, the legs and ventral surface aiso albo-setose. Rostrum short, broad, widened outwards,

closely punctate, with an elongate-triangular depression extending upwards to near the small inter-

ocular fovea, the depression limited on each side by an oblique ridge and subcarinate down the middle,

the eyes not prominent. Prothorax broader than long, margined at the base, gradually narrowing from

near the hind angles in 2, somewhat rounded at the sides and constricted behind in ¢ ; with irregularly

distributed, large, scattered, foveiform punctures intermixed with a close fine interstitial punctuation,

and shallowly, interruptedly sulcate down the middle. Scutellum not visible. Elytra oblong-oval,

moderately convex and narrow in ¢, broad in @, the humeri distinct in this sex; with rows of coarse

punctures, the punctures somewhat widely separated in 2, the interstices almost flat, the alternate ones

slightly raised towards the sides and apex in one @.

Length 8-11, breadth 24-4! millim. (¢ 2.)

Hab. Mexico (Truqui, in coll. Fry).

One male and two females. Near £. marginatus (=insolitus), Sharp, the elytra more

rounded at the sides anteriorly in the male and with distinct humeri in the female ;

the prothorax with more numerous foveiform depressions on the disc and the median

sulcus shallow or almost wanting; the upper surface (?abraded) more sparsely

squamose.

40 (s). Epiceerus foveifrons, sp.n. (Tab. XV. fig. 12, ¢.)

Oblong, convex, narrow (¢), broader (2), shining, black; above very sparsely, the under surface more

densely, cinereo-squamose. Rostrum short, widening outwards, with an elongate-triangular excavation

extending upwards to near the large inter-ocular fovea, the depression limited on each side by an oblique

ridge. Prothorax transverse, convex, sharply margined at the base, rounded at the sides, narrowed and

constricted in front and also constricted behind ; with a few large foveiform punctures intermixed with a

close, fine, interstitial punctuation, and also very deeply sulcate down the middle. Scutellum not visible.

Elytra oblong-oval, convex and narrow in dg, broader in Q ; the seriate punctures coarse and closely placed,

transverse in 9, the interstices more or less convex throughout. Anterior tibie strongly curved in ¢.

Length 81-9, breadth 3-32 millim. (3 2 .)

Hab. Muxico (Boucard, ex coll. Solari: 9), Salazar (Wickham: ¢ , type).

Very near FE. truquianus, from which it differs in having the frontal fovea much

larger; the prothorax more convex, deeply sulcate, and with fewer fovee ; the elytra

more convex in both sexes, the seriate punctures closely placed, and the interstices

raised throughout. The male (type), recently sent us by Mr. Wickham, is rather worn

and almost glabrous above, the female is squamose on the apical declivity. E. hoegez,

from Salazar, based upon a single female example, is a more elongate, less convex form,

with a feebly impressed rostrum, an obsoletely grooved prothorax, and flat elytral

interstices.

Epicerus godmani (p. 124).

The types of this species (two examples from Popocatepetl) are certainly males, and

we have also another agreeing with them from Flohr’s duplicates, with a dealer’s label

“Sierra de Durango” attached. The scattered denticles on the anterior tibie are

almost obsolete in £. godmani and the allied E. scutellaris.

Epicerus sexcostatus (p. 125).

The male of this species is narrower than the female, and it has the metasternum

and first ventral segment broadly hollowed down the middle. The British Museum

has recently received a female of it from Vera Cruz, found by Mr. Crawford. Both

sexes were obtained at Cinco Sefores.

EPAGRIOPSIS, nomen nov.

Epagrius, Sharp, antea, p. 128 (nec Schonherr).

Dr. Sharp in his remarks on Schénherr’s genus EKpagrius says that his application

of this name may possibly prove to be erroneous, as he had not been able to see

a specimen of the type, EL. nubilosus. This is actually the case, the type from the

Sommer collection (kindly lent by Prof. Poulton) proving to be a Bradyrhynchus

and synonymous with B. tolucew, Sharp. The twenty-one species provisionally placed

under Hpagrius in this work therefore require a new generic name, for which

Epagriopsis is suggested ; Bradyrhynchus, Sharp, becomes a synonym of Kpagrius,

Schénh. In the enumeration of the members of the present genus (anted, pp. 129-

140) both Epagrius nubilosus (the type) and metallescens were by some oversight

RHYNCHOPHORA: OTLORHYNCHINA. 329

omitted; the last-mentioned insect, however, is merely a large rubbed female of

£. nubilosus. Synthlibonotus, Schonh., type 8. rufipes, Lacord., from Colombia, is very

nearly related to Hpagriopsis, but differs from it in having the femora strongly pedun-

culate, and the scrobes * shallower and broader towards the eyes.

This change in the synonymy has already been alluded to under Epagriopsis, antea,

330 SUPPLEMENT.

In addition to the two specimens from Toluca mentioned by Dr. Sharp, I have seen

three others found by Truqui and the types of the insects described by Boheman,

E. metallescens being a large, somewhat abraded, submetallic example of the same

species. The common, Y-shaped, fuscous-edged, white mark on the apical declivity of

the elytra and the white oblique fascia on the outer part of the disc before the middle

are conspicuous in all of them. Length 6-74, breadth 23-33 mm.

Bradyrhynchus rugicoliis, antea p. 142.

Epicerus notatus (2°) and punctaticollis (3), E. Dugés, in litt.

There are two examples of this species (described from an abraded female) in the

U.S. National Museum, doubtless from the same locality as the type, Guanajuato. One

of these additional specimens, the female figured, is in fairly good condition; it has

two sinuous vitte on the disc and a stripe on each side of the prothorax, and a patch at

the sides and a common broad, angulate, subapical fascia on the elytra, cinereous.

4, Epagrius retrorsus, sp.n. (Tab. XV. figg. 15, 15 a.)

Oblong-obovate, black, the antennz (the club excepted) and tarsi more or less ferruginous; densely clothed

with pale brown and white scales, the white scales on the prothorax condensed into a narrow, faint,

curved stripe on each side, and those on the elytra into two sharply defined, rather broad, angulate

fascie—the anterior one not reaching the suture and extending forward along the outer margin to

the shoulder, the subapical one extending for some distance down the suture; the surface also some-

what thickly set with short, stout, curved setw. Head transversely depressed between the eyes

(appearing sharply separated from the rostrum), the rostrum short, the eyes prominent, the antennal

club ovate and rather short. Prothorax transverse, rounded at the sides ; coarsely, somewhat closely

punctate, and faintly canaliculate. LElytra at the base a little wider than the prothorax, retuse or

perpendicular on the apical declivity (as seen in profile), the seriate punctures scattered and very con-

spicuous, the interstices rather convex.

Length 5-6, breadth 23-22 millim.

Hab. Mexico (Mus. Brit. ; Trugut, in coll. Fry).

Five specimens, sex not ascertained. Not unlike FE. nudilosus (=toluce, Sharp),

but strongly setose, and with the apical declivity perpendicular, the prothorax more

closely punctured, and the head transversely depressed between the eyes. L. rugicollis

(Sharp) has very short, fine, inconspicuous sete and the apical declivity rounded,

though agreeing with L. retrorsus in the form of the head. The Guatemalan Epicerus

_gninor, too, is not unlike the present species, but it has depressed eyes, erect sete, and

an unimpressed head.

CLEISTOLOPHUS (p. 143).

Cleistolophus subfasciatus (p. 143).

To the localities given, add :—Mexico, Oaxaca (Mus. Brit.).

RHYNCHOPHORA: OTIORHYNCHIN-E. 331

1 (a). Cleistolophus viridimargo, sp.n. (Tab. XV. figg. 16, 16a.)

Elongate, subconical, black; densely clothed with brown scales, the prothorax and elytra with a sharply-

defined, broad, greenish-white stripe along the flanks, which extends obliquely and interruptedly inwards

across the disc towards the apex, the head beneath, the basal margin of the prothorax, a common

cordiform apical patch on the elytra, the legs, and the under surface in great part, also viridi-squamose.

Rostrum subquadrate, slightly hollowed down the middle, the upper portion narrowing towards the

apex ; eyes large, depressed ; joints 1 and 2 of the funieulus equal in length. Prothorax transverse,

obliquely narrowed in front, subparallel at the base, the base sharply margined; finely punctate.

Elytra elongate, acuminate at the apex, of the same width as the prothorax at the base, and constricted

immediately behind the prominent humeri, the sutural region tumid on the anical declivity, the scattered

seriate punctures showing conspicuously through the dense vestiture. Anterior and intermediate femora

dentate.

Length 114, breadth 5 millim.

Hab, British Wonpuras (Dyson, in Aus. Brit.).

One specimen. Larger and much more elongate than C. sudfasciatus, the eyes

larger, the rostrum with more prominent ale, the prothorax and elytra with a sharply-

defined, broad, pale greenish stripe along the flanks, the stripe turning obliquely inwards

across the disc towards the apex.

Cleistolophus similis (p. 144).

To the localities given, add:—Mexico, Chiapas (Jfus. Prit.); Costa Rica, San

José, Escazu (Biolley), Savanillas de Pirris, Azahar de Cartago (Underwood), Lucurrique

(U.S. Nat. Mus.).

A common insect in Costa Rica and labelled by Biolley as having been found ona

Croton at Escazu. Some of its varieties are scarcely separable from C. instadilis, which

specimens found by Messrs. Barber and Schwarz at Cacao, near Trece Aguas *.

BOTHYNODONTES (to follow the genus Lyrtosus, p. 151).

Bothinodontes, Kirsch, Berl. ent. Zeitschr. 1867, p. 24.

Bothynodontes, Scudder, Nomencl. Zool. ii. p. 42 (1882).

In the British Museum collection there are two broken pinned examples of an insect

clearly belonging to this genus, the unique type of which, &. squalidus, Kirsch, from

Colombia, has been kindly communicated by Dr. Heller. Lvepsimus, Schonh., type

E. setiferus, Boh., from Brazil, superficially resembles Lothynodontes, differing from

the latter in having ocular lobes to the prothorax and the anterior femora simply

clavate. Following Dr. Sharp’s system of classification (antea, pp. 101, 102), Bothyno-

dontes would perhaps be best placed near Lpitosus and Eumestorus ; the free tarsal

claws, &c., exclude it from the Sciapuilina. The Mexican habitat requires con-

firmation.

3352 SUPPLEMENT.

1. Bothynodontes gibbipennis, sp. n. (Tab. XV. figg. 17, 17 a.)

Obovate, ferruginous, shining; variegated with a dense clothing of pale brown and whitish scales, the elytra

with a spot on the third interstice before the middle and an irregular oblique median fascia black, the

latter followed by an oblique indeterminate whitish band ; the upper surface also set with scattered, erect,

stout, clubbed sete, these becoming black and clustered into a small tuft. on the tumid portion of the third

elytral interstice. Rostrum feebly curved, parallel-sided as seen from above, longer than the head and

separated from it by a transverse groove, the scrobes long, deep, and sinuously descending, the head

finely canaliculate between the eyes, the latter separated by much less than the width of the rostrum ;

antennz long, slender, joints 1 and 2 of the funiculus subequal in length, the club long and abruptly

acuminate. Prothorax nearly as long as broad, obliquely narrowed in front and behind, truncate at the

base; uneven, densely, finely punctate, and obsoletely canaliculate. Scutellum not visible. Elytra

short, ovate, transversely gibbous ; 9-striate, the strie coarsely punctured, the interstices convex, the

third tumid at about one-fourth from the base. Anterior femora very strongly clavate and also angulato-

dilatate, the intermediate and posterior pairs stout. Anterior tibie curved, unguiculate. Third tarsal

joint broadly bilobed, the claws free.

Length 34, breadth (of elytra) 12 millim.

Hab. Mexico (Mus. Brit.).—Cotomsia (Mus. Brit.).

Separable at once from DB. squalidus by the more inflated, maculate elytra and the

distinctly curved rostrum. ‘The setigerous prominence on the third elytral interstice is

also characteristic.

The two specimens before me from Coahuila are larger than a cotype of &. laticeps

from Arizona sent to Dr. Sharp by Capt. Casey, and have the prothorax a little more

constricted before the middle, one of them, too, has longer erect scales than the other.

E. constricta seems to be a form of the same species, both occurring in Arizona. In

this genus the vibriss are strongly developed, but the ocular lobes are wanting.

PANTOMORUS (p. 152).

Aramigus and Phacepholis, Horn, Proc. Am. Phil. Soc. xv. pp. 98, 95 (1875).

Amongst the thirty-two Central-American species placed by Dr. Sharp under

Pantomorus (type P. albosignatus, Boh.) some, P. longulus, P. distans, &c., have the

tips of the hind tibie furnished with, at most, a double row of fimbrie (= Aramiqus,

Horn); others, nos. 25-50, &c., have the tips of the hind tibie dilated into an oval

enclosed scaly space (= Pantomorus, Schénh., sensu stricto, and Phacepholis, Horn) ;

others. again are intermediate in this respect, and Horn’s genus Aramigus would

therefore be better sunk under Pantomorus*. P. globicollis, the type of Athetetes,

Pascoe, has the tips of the hind tibiz squamose as in Phacepholis, and the second

ventral segment of the male armed with two or three small transversely placed

tubercles. The males of Phacepholis elegans and P. candida, Horn (if the insects

sent me under these names by the U.S. National Museum are correctly named), have

similar tubercles on the second ventral segment (elegans, 5, and candida, 2), though

this character is not mentioned by the American author; Pierce, too, in his recent

revision of the genus Phacepholis |Journ. icon. Ent. iii. p. 8363 (1910)] appears to have

also overlooked them.

Pantomorus albosignatus (p. 153).

To the Mexican localities given, add:— Chihuahua city, Guadalupe, Distrito

Federal (Wickham), Hidalgo (Barrett, in U.S. Nat. Mus.), Mescala (H. H. Smith),

Oaxaca (Mus. Brit.), Cordova (fige).

Mr. Wickham has recently sent us numerous fresh examples of this insect from

Chihuahua, Durango, and Guadalupe. ‘There is no record of it as yet from north of

the Mexican frontier.

Hab. Norra America, New Jersey !, Montana!, Georgia ®, California, &c.—Mexico,

Guanajuato (Dugés, in Mus. Brit.; U.S. Nat. Mus.).

Specimens of this destructive insect were sent by Dr. Dugés, of Guanajuato, to the

British Museum in 1901, and its real home may be in Mexico, the species having

perhaps been introduced into the United States, as well as into the Hawaiian Islands °.

* Faust has referred a Venezuelan insect to Phacepholis, P. albaria.

+ The other Central-American forms (of which the males are known) possessing this character are

P. brevipes, annectens, albicans, and viridicans, Sharp, and a new species described below.

354 SUPPLEMENT.

P. fulleri is closely allied to the Mexican P. longulus, Sharp (which is also an

Aramigus, sensu Horn), but differs from it in having a few stout, pallid, squamiform,

decumbent sete on the elytra (instead of numerous long erect bristly hairs), these

becoming conspicuous on the apical declivity. ‘The Hawaiian insect has already been

identified by Prof. Chittenden [Bull. U.S. Dept. Agric., Ent. no. 27, pp. 88-96 (1901) ].

In the United States the species attacks roses, Azalea, &c., and it is often found in

ereenhouses. The habits of P. fullert have been described by Chittenden, Schwarz,

Koebele, and Pierce. The Mexican examples agree perfectly with others before me

from Iowa, &c. I am unable to certainly identify the sexes, though both are

apparently represented in the series before me.

Pantomorus crinitus (p. 157).

Pantomorus affinis, antea, p. 157.

To the localities given, add :—Mexico, Santa Lucrecia in Vera Cruz (Knad, in U.S.

Nat. Mus.) ; Guatemata (Mus. Brit.), San Isidro (Champion); SALVADOR, San Salvador,

Izalco (Xnab, in U.S. Nat. Mus.).

The very long series of this insect now available for examination connects P. affinis,

Sharp, with the variable P. crinitus, Boh., the feeble submarginal carine of the rostrum

in P. affinis proving to be evanescent, and sometimes present on one side and wauting

on the other. In one of the fusco-maculate males amongst the Tapachula series

referred by Dr. Sharp to P. crinitus the middle tibize are distinctly unguiculate,

showing that this character also (used by him for grouping the species) is inconstant.

P. nobilis, Boh., cannot be certainly identified from the fresh material.

13 (a). Pantomorus horridus, sp.n. (Tab. XV. figg. 20, 20a, 2.)

Oblong (¢), subpyriform (2), convex, black; densely clothed with pale bluish-grey scales, in the ¢ with

intermixed green scales on the elytra, and also thickly set with long, erect, bristly, whitish hairs,

Rostrum slightly hollowed down the middle anteriorly, canaliculate; eyes not very prominent ; antenne

comparatively stout, joint 2 of the funiculus less than twice as long as 1. Prothorax strongly trans-

verse, subtruncate at the base, moderately rounded at the sides; densely, finely punctate. LElytra

convex, oval, very little wider than the prothorax in d, broader and more rounded at the sides in 92,

the seriate punctures (as seen through the vestiture) fine and scattered, the interstices flat. Anterior

tibiee denticulate; intermediate tibie unguiculate in ¢, and with a very short uncus in @; posterior

tibiee without definite enclosed space at the tip.

Length 43-63, breadth 2-23 millim. (d 9.)

Hab. Mexico (Loge, ex coll. Solari: 3), Mazatlan (Hoge: ¢@).

Two specimens, assumed to be sexes, both having the eyes less prominent than

usual, a peculiarity separating P. horridus from all the varieties of P. crinitus, the

latter also having longer and more slender antenne, and the middle tibie of the male

not or feebly unguiculate. ‘The characters used by Dr. Sharp would require to be

modified to include P. horridus in his Group 1. The rather worn male, taken as the

RHYNCHOPHORA : OTIORHYNCHIN 2. 339

type, has a more distinctly visible scutellum than the female, but too much importance

need not be attached to this; the female is in very fresh condition.

Pantomorus faber (p. 159).

To the Costa Rican locality given, add:—San José (Biolley), Monte Retondo

(Underwood).

This insect, to judge from a specimen incorrectly labelled “Guat.” in the British

Museum, appears to be the P. subcinctus of Jekel’s collection, and not the one

identified under that name by Dr. Sharp.

Pantomorus picturatus (p. 160).

To the localities given, add :—Satvapor, San Salvador (nad, in U.S. Nat. Mus.).

A single fresh example (2), with the suture anda broad curved stripe down the

outer part of the disc of each elytron, and a narrower stripe along each flank of the

prothorax, densely clothed with pale greenish scales, which are almost covered by an

ochreous powdery exudation.

Pantomorus stupidus (p. 161).

To the Mexican localities given, add :—Salina Cruz and Tehuantepec in Oaxaca

(nab, in U.S. Nat. Mus.), Chiapas (Sadlé).

Some of these additional specimens are sharply lineate with a sulphur-yellow

exudation. They were found with Naupactus sulfuratus at the same localities in

Oaxaca, and it has been suggested (anted, p. 232) that the latter prove to be a winged

form of P. stupidus.

Pantomorus wniformis (p. 161).

To the Mexican locality given, add:—Rincon Antonio and Almoloya in Oaxaca

(Knab, in U.S. Nat. Mus.).

A long series, some with the alternate elytral interstices blue or green and the

others golden, this appearance being in part due to the arrangement of the yellow

exudation. See remarks under Naupactus virescens, antea, p. 233. Both P. stupidus

and P. uniformis belong to Phacepholis, Horn.

Pantomorus rufipes (p. 161).

The types (2) of this insect are males and we have another specimen of the same

sex from Jalapa. A worn female from Cordova, with the scales cupreo-cinereous

(instead of green), seems to belong to the same species. All four examples have the

intermediate and posterior tibiz feebly denticulate towards the apex, the anterior pair

with more distinct scattered teeth.

336 SUPPLEMENT.

Pantomorus distans (p. 162).

To the localities given, add:—Costa Rica, Monte Retondo (Underwood: 3 2),

Piedras Negras (U.S. Nat. Mus.: 3 2).

Described from two males. The Costa Rican examples (and the Bugaba specimen

figured to a less extent) have the sutural region of the elytra more or less thickly

clothed with green or golden-green scales. ‘The second ventral segment of the male is

without tubercles and the first depressed down the middle. ‘The hind tibie are

narrowly laminate and bifimbriate at the tip, instead of having an oval squamose space

as in all the other species placed by Dr. Sharp in his Group 2 of the genus.

Pantomorus globicollis (p. 163). (Tab. XV. figg. 21, 21a, b, ¢, var.)

To the localities given, add :—Mexico, Tehuantepec and Almoloya in Oaxaca

(Knab, in U.S. Nat. Mus.: 3 2); Costa Rica, Guanacaste (Pittier: ¢ ).

The numerous specimens seen from Tehuantepec (fig. 21) have the scales on the

upper surface brown, and the flanks of the prothorax and the interrupted fasciz or

spots on the elytra cinereous. The three females from Almoloya are as large as

P. robustus, and have the light scales on the prothorax and elytra metallic green.

The hind tibize have an oval squamose space at the tip as in Phacepholis. ‘The second

ventral segment of the male has two (larger) or three (smaller) tubercles (fig. 21 6).

Pantomorus albicans (p. 164). (Tab. XV. fig. 22, ¢, abdomen.)

In one of the specimens found at Acapulco by Mr. Knab (in the U.S. National

Museum) the prothorax and elytra are conspicuously brunneo-vittate, others from the

same locality being uniformly cinereous. LP. albicans is a Phacepholis, sensu Horn.

The ventral teeth of the male (fig. 22) are very conspicuous.

Epicerus viridis, Dugés in litt’.

Hab. Norra America, San Antonio, Texas ®.—Mexico, Guanajuato 3 (Dugés, in U.S.

Nat. Mus. ; Sallé), ‘ Sierra de Durango” (Hége, in coll. Solari).

We have received from the U.S. National Museum a male of Phacepholis elegans,

Horn (with a transverse series of five small tubercles on the second ventral segment

and the intermediate tibiz strongly unguiculate), from San Diego, Texas, and a female

“co-type” of P. viridis, Chittenden, labelled San Antonio, Texas. According to Pierce 2,

these insects are synonymous; but in this I cannot agree with him, the female (viridis)

having much more prominent eyes than the male (elegans) and the elytra very convex

* Prof. Chittenden informs us that he will shortly publish a description of this insect.

RHYNCHOPHORA : OTIORHYNCHIN &. 337

and acuminate-ovate in shape. Ihave seen three other females, from Mexico, agreeing

exactly with the one from San Antonio; the male will doubtless prove to be nearly

related to that of P. elegans. The last-mentioned insect is said to live on cotton

( Gossypium).

29 (s). Pantomorus trituberculatus, sp. n.

Oblong, narrow (3), broader (2), black; thickly clothed with greyish-brown scales, the prothorax with

indications of two faint vitte on the dise and a stripe on each flank, and the elytra with the sides, base,

and in one specimen several faint oblique or oblong streaks on the disc, indeterminately whitish or

cinereous, the intermixed scattered sete very short and inconspicuous. Rostrum flattened above, the

narrow median sulcus extending upwards to the feeble, transverse, post-ocular depression of the head ;

eyes very prominent ; antenne Jong and slender, joint 2 of the funicnlus elongate, much longer than 1.

Prothorax convex, transverse, relatively narrower and longer in ¢, rounded at the sides, subtruncate at

the base, densely, finely punctate and canaliculate. Elytra a little broader than the prothorax in 6,

wider in 2, suboval, truncate at the base, the humeri distinct; punctate-striate. Tibiw# and tarsi

comparatively slender; anterior tibie closely denticulate ; posterior tibixe feebly lamellate at the tip.

3. Intermediate tibie strongly unguiculate ; second ventral segment armed with three, transversely placed,

small black tubercles.

Length 53-84, breadth 2-3 millim. (¢ 92.)

Hab. Mexico, Tehuantepec in Oaxaca (Anab, in U.S. Nat. Aus.).

Three males and two females, all somewhat worn, one of each sex retained for the

British Museum. A small narrow form (at least in male), with comparatively slender

tibiz and tarsi, the prothorax and elytra subtruncate at the base, the second ventral

segment trituberculate in the male, &c.

Pantomorus femoratus (p. 165).

To the localities given, add :—Nicaragua, San Marcos and Chinandega (Baker) ;

Costa Rica, Guanacaste (Pittier), Escazu (Biolley), Atenas, Piedras Negras, Las Loras

near Puntarenas (U.S. Nat. Mus.).

The type (¢) of this species is immature. We have nowreceived a long series of it

from Costa Rica. They have the vestiture uniformly whitish or cinereous, often with a

greenish, cupreous, or brownish tinge. The male has the second ventral segment unarmed

and the first segment hollowed down the middle. The under surface is thickly clothed

with long erect white hairs. The hind tibiew have an oval squamose space at the tip.

Pantomorus robustus (p. 166).

Two abraded females from Momotombo, Nicaragua, sent us by Mr. Wickham, may

belong to this species. It is not at all improbable that P. robustus, described from two

females from Chontales*, is the sexual complement of P. strabo, described from a

single male from the same locality, the great difference in size and in the colour of

the scales notwithstanding, P. globicollis varying in a similar way. The eyes are feebly

convex in both P. strabo and P. robustus, but less depressed than in P. sulfureus.

* There is also another female of it from Nicaragua in Signor A. Solari’s collection.

33. Pantomorus sulfureus, sp. n. (Tab. XV. figg. 24, 244, 3.)

Moderately elongate, convex, black, the tarsi sometimes obscure ferruginous ; densely, uniformly clothed with

pale green scales and when fresh covered with a yellow exudation, the elytra also set with rather long

fine erect hairs, the ventral surface pilose. Rostrum flattened, canaliculate, the upper portion slightly

narrowing forwards; eyes oval, depressed ; antenne moderately slender, joint 2 of the funiculus one-

half longer than 1. Prothorax transversely convex, strongly so and as wide as the elytra in ¢, much

broader than long, rounded at the sides, the base bisinuate (appearing obliquely truncate on each side) ;

densely, finely punctate and obsoletely canaliculate. Elytra convex, oval, the base (as seen from above).

conjointly hollowed in the middle and obliquely cut off on each side; finely punctate-striate, the

interstices almost flat. Anterior tibie denticulate; intermediate tibie feebly unguiculate in d ;

posterior tibie with an oval squamose area at the tip.

Length 63-114, breadth 23-44 millim. (¢ @.)

Hab. Mexico, Salina Cruz in Oaxaca, Pacific slope (nad, in U.S. Nat. Mus.).

Twelve specimens, mostly in beautifully fresh condition. Amongst the described

Mexican species of the genus this insect can only be compared with P. (Phacephoiis)

uniformis, from which it is at once separated by the depressed eyes, and the more

strongly sinuate base of both the prothorax and the elytra. P. suifwreus has the

prothorax globose in the male, as in P. (Athetetes) globicollis; but the middle tibie

are much more feebly unguiculate in this sex. The second ventral segment of the

male is without tubercles.

PSEUDOPANTOMORUS, gen. nov. (to follow Pantomorus, p. 166).

Head very broad, short, together with the eyes as wide as the widest part of the prothorax ; eyes very

prominent, convex, strictly lateral; rostrum short, subquadrate, narrowing a little towards the apex,

the scrobes narrow, deep, sinuous, descending to slightly below the eyes; prothorax transverse, truncate

at the base; scutellum minute or invisible; elytra oval, truncate at the base, the humeri distinct ;

ventral segment 2 about as long as 3 and 4 united; legs short, stout; femora unarmed, the anterior

pair subangulate ; anterior and intermediate tibiw unguiculate, the anterior pair obsoletely denticulate ;

posterior tibie with a narrow squamose area at the tip, the glabrous articular area extending upward ;

tarsal claws connate at the base; body oblong, robust, densely squamose and setose, apterous.

Type, P. latefrons.

The single species belonging to this genus may be briefly described as a small

Pantomorus with a very broad head, short rostrum, prominent eyes, short, stout legs,

and basally conuate tarsal claws. It bears a superficial resemblance to Caulostrophus

and various elongate species of Strophosomus (S. ebenista, &c.).

1. Pseudopantomorus latifrons, sp. n. (Tab. XV. figg. 25, 25a, 3.)

Convex, black ; variegated above with a dense clothing of light and dark brown scales, the dark brown scales

on the elytra condensed into a transverse or curved mark below the base, extending forward along the

third interstice to the anterior margin, an angulate median fascia (not reaching the suture), and a small

triangular patch on the disc towards the apex, the scales along the exposed basal margin of the head, at

the base of the femora above, and on the under surface paler or whitish ; the elytra also thickly set with

long, stiff, erect seta, and the rest of the surface with short setiform scales. Head and rostrum finely

canaliculate, the rostrum hollowed towards the apex; joint 2 of the funiculus nearly twice as long as 1.

Prothorax much broader than long, rounded at the sides, in the ¢ not narrower at the apex than at the

base, densely, finely punctate. Elytra oval, convex, rather short, constricted immediately below the base,

2. Elongate, narrow, shining, black, the antennew (the club and apex of scape excepted) rufo-testaceous ;

thickly clothed (except on the small smooth spots along the elytral interstices) with pale bluish-grey

scales, the elytral interstices also each set with about two rows of closcly placed, stiff, erect, moderately

long, dark sete. Head as long as the rostrum, the eyes large; antennie very slender, long, joint 1 of

the funiculus much longer than 2, about equalling 3 and 4 united, the scape extending to considerably

beyond the eyes. Prothorax transverse, somewhat rounded at the sides, densely finely punctate

Scutellum small, transverse, squamose. Elytra elongate, convex, ovate, at the base very little wider

than the prothorax, strongly sinuate along their lower edge ; punctate-striate, the interstices almost flat.

Length 54, breadth 2 millim.

Hab. Mexico, Iguala in Guerrero (Lf/dge).

One female. Near D. setosus and D. scutellaris, but with shorter and more abundant

erect setosity on the elytra, the scales uniformly glaucous, the prothorax as finely

punctured as in D. scutellaris.

CAUTODERUS (p. 169).

2. Cautoderus nigrocinctus, sp.n. (Tab. XV. fig. 27.)

Elongate, narrow, shining, black; thickly clothed with metallic golden-green scales, except on the followinz

parts, which are bare or very sparsely clad with small blackish scales—a space behind each eye, a

submarginal vitta on each side of the prothorax, and the suture and three transverse fascic on the

elytra (the second and third connected along the fourth interstice, as well as along the suture) ; the

upper surface also set with numerous erect sete, those on the elytra long and closely placed down each

interstice, the others short. Head a little longer than the rostrum; [antennal scape long, extending

beyond the eyes, joints 1 and 2 of the funiculus subequal in length, 1 a little longer than 2, conical, the

others short and subconical *]. Prothorax broader than long, bisinuate at the base, narrowed anteriorly,

densely, finely punctate. Scutellum minute, acuminate. Elytra elongate, moderately convex, con-

siderably wider than the prothorax, subparallel in their basal half, the humeri tumid and somewhat

prominent; coarsely punctate-striate, the interstices feebly convex and each with a row of very small

smooth spots indicating the position of the sete. Anterior femora strongly, the others more feebly, clavate,

Length 53, breadth 2 millim. (¢?)

Hab. Mexico (ex coll. Jekel).

One specimen, kindly presented to us by Signor A. Solari. Larger and more robust

than C. mexicanus, Sharp, the femora especially stouter, the scales golden-green, the

sete much longer, the humeri more prominent, &c. The black markings may be

partly, but not entirely, due to abrasion. The second ventral segment is comparatively

short.

PYTHIS, gen. nov. (to follow Sciadrusus, p. 172).

Rostrum very short and broad, not longer than the exposed part of the head, the upper portion obliquely

narrowing from the eyes te the points of insertion of the antenne, the scrobes lateral, narrow, abruptly

angulate, and descending ; head broad, the eyes prominent and rather large; autenne very slender, the

scape abruptly clavate at the tip and reaching the front of the prothorax, joint 1 of the funiculus twice

as long as 2, 3-7 short and obconic, the club long and acuminate; mentum almost filling the buccal

cavity, tumid down the middle; prothorax ample, transverse; scutellum minute; elytra oval, short,

the humeri distinct, the lower margin feebly sinuate; ventral segments 2 and d subequal in length,

3 and 4 short, the first suture arcuate; legs slender; anterior tibia unguiculate; articular surface of

posterior tibie terminal; tarsal claws subconnate at the base; body convex, apterous, squamose and

setose.

Type, P. amplicollis.

This genus belongs to the Sciaphilina as defined by Dr. Sharp (anted, p. 167).

The relatively broader head and prothorax and the short oval elytra distinguish it

from Mitostylus, Chetopantus, Sciadrusus, kc. The distinctly developed humeri and

the broad head and prothorax separate Pythis from Sciomias.

1. Pythis amplicollis, sp.n. (Tab. XV. figg. 28, 28 a.)

Ovate, shining, piceous, the antenne (the tip of the club excepted) and tarsi rufo-testaceous; variegated with

pale brown, fuscous, and whitish scales, the whitish scales condensed into a stripe along each side of the

head and prothorax, and a streak at the base of the fifth and seventh elytral interstices, the prothorax

with three faint darker brown vitte on the disc; the upper surface also set with numerous short, erect,

fine, pallid sete, those on the elytra uniseriately arranged down each interstice. Head (with the

promineut eyes) nearly as wide as the prothorax, the rostrum flattened, obsoletely carinate down

the middle anteriorly, both densely, rugulosely punctate, Prothorax constricted just before the middle,

narrowed in front and behind, punctured like the head. Elytra considerably wider than the prothorax,

convex, punctate-striate, the punctures very fine (as seen with the vestiture intact, but when the scales

are removed appearing coarse and closely placed), the interstices convex.

Length 4, breadth 13-1} millim. (@.)

Hab. Mexico (Trugut), Sierra de Durango (Hége, in coll. Solari).

RHYNCHOPHORA: OTIORHYNCHIN &. 341

Two specimens, precisely similar, one certainly a female, the example found by

Hoge in very fresh condition.

ISODACRYS (p. 175).

3 (a). Isodacrys schwarzi, sp.n. (Tab. XV. figg. 29, 29 a.)

Oblong, black; variegated with a dense clothing of rather large, white, pale brown, and blackish scales, the

white scales condensed into two vittw on the disc of the prothorax, and an oblique irregular or inter-

rupted subapical fascia and various spots or streaks on the elytra (the prothoracic vittz extending for a

short distance down the base of the latter); the scales on the under surface and legs whitish; the surface

also set with extremely minute, curled, scattered, setiform hairs. Eyes very small. Prothorax elongate,

constricted towards the apex. Elytra oval, short, much wider than the prothorax, abruptly narrowed

posteriorly, the sutural region tumid and obtusely projecting near the tip, the seriate punctures almost

hidden by the dense vestiture. Anterior tibie sharply unguiculate, the denticles along the inuer edge

wanting.

Length 24-22, breadth 14 millim.

Hab. Mexico, Monterey in Nuevo Leon (Schwarz, in U.S. Nat. Mus.).

Two specimens, one of which has been presented to us by the U.S. National

Museum. They are labelled as having been captured by Mr. E. A. Schwarz on Jan. Ist.

This species differs from all those described by Dr. Sharp in its non-denticulate

anterior tibia and very small eyes. It approaches L. meaicanus, but has much broader

elytra and the sutural region more produced towards the apex.

PERITELINA.

EUPERITELUS, gen. nov.

Rostrum short, stout, alate, separated from the head by a transverse groove, the scrobes superior, short,

curving inwards behind; eyes superior, rounded, convex, rather small, the head dilated on each side

beneath them; antenne with a very stout, long, cylindrical, curved scape, extending to beyond the

anterior margin of the prothorax, joints 1 and 2 of the funiculus subequal in length, 3-7 transverse ;

mentum rounded, rather small; prothorax short, truncate and feebly margined at the base; scutellum

wanting ; elytra broad-ovate; metasternum short, the episterna exposed ; ventral segment 2 much shorter

than 3 and 4 united, the suture between 1 and 2 sinuous; legs stout; femora unarmed ; tibie feebly

unguiculate, the posterior pair denticulate along their inner edge towards the apex, the glabrous articular

surface terminal, the corbels open ; tarsi broad, the claws connate; body apterous, obovate, squamose.

Type, Z. albovarius.

Amongst the N.-American forms this remarkable Peritelid can only be compared

with Thricolepis and Peritelopsis, following Horn’s system of arrangement. ‘lhe

superior, convergent scrobes, the prominent, superiorly placed eyes, the transversely

grooved base of the rostrum, and the denticulate posterior tibie are its chief

characters. Euperitelus has wholly the facies of an Otiorhynchus.

1. Euperitelus albovarlus, sp.n. (Jab. XV. figg. 30, 30a.)

Broad, black; variegate with a dense clothing of brown and white scales, the white scales clustered into an

irregular, incomplete sinuous submarginal stripe on each side of the prothorax and into numerous

small scattered subconfluent patches on the depressed portions of the elytra, the granules bare; the

antenne (the fuscous club excepted), legs, and under surface setulose and densely squamose. Head and

rostrum densely, finely punctate, the head longitudinally grooved between the eyes, the rostrum slightly

342 SUPPLEMENT.

hollowed down the middle. Prothorax transverse, rounded at the sides, nearly as wide at the apex as at

the base; feebly granulate and densely finely punctate. Elytra at the middle nearly twice as wide

as the prothorax, convex, rounded at the sides ; with ten rows of scattered rather coarse punctures placed

upon almost obsolete striz, the punctures separated one from another by a smooth transverse or rounded

tubercle.

Length 101, breadth 43 millim. (@ ?)

Hab. Mexico, Sierra de Durango (Hége, ex coll. Solari).

One specimen, from the last collection made by Hoge, and given to us for description

by Signor A. Solari.

TRACHYPHLGINA.

TRACHYPHLG@OMIMUS, gen. nov.

Rostrum short, stout, the scrobes lateral, deep, descending direct to the lower anterior margin of the eyes ;

eyes coarsely facetted, not prominent, moderately large; antenns with a gradually widened scape,

reaching the front of the prothorax, the funiculus rather slender, joints 1 and 2 equal in length,

3-7 short and moniliform, the club stout and ovate; mentum small; prothorax transversely oval;

scutellum very minute or not visible; elytra short, oval; metasternum short, the episterna very narrowly

exposed; ventral segment 2 as long as 3 and 4 united, the first suture feebly arcuate ; femora clavate,

unarmed; tibia sinuate within, strongly unguiculate, and each armed with a row of closely placed stiff

bristles at the apex (fig. 816); tarsal claws long, divergent; body densely squamose and setose, and also

coated with an earthy incrustation, apterous.

Type, 7. spurcus.

This genus also includes Trachyphlaus solitarius, Sharp, both species differing from

Trachyphleus in having the tibiz closely ciliate with short stiff bristles at the apex

(in Trachyphleus they are armed with from three to five tooth-like spines along the

apical margin), the funiculus more slender, and the prothorax more developed.

Hypsometopus, type H. inguinatus, Kirsch (the type of which I have seen), from

Colombia, comes near these Mexican insects; but it has the scrobes descending at

some distance before the eyes, the antennal club longer, the legs more elongate, &c.

The N.-American Phyxelis, Schénh., has superiorly placed scrobes, &c.

1. Trachyphleomimus spurcus, sp.n. (Tab. XV. figg. 31, 31a, 3.)

Oblong-ovate, black, the antenne (the scape excepted) and tarsi ferruginous; densely clothed with brown

scales, which are partly hidden beneath an earthy incrustation, the entire surface (antenne and legs

included) also set with rigid, scattered, stout sete, those on the elytra long, clubbed, and uniseriately

arranged down each interstice. Rostrum subquadrate, feebly transversely depressed at the base,

obsoletely canaliculate, the head also feebly depressed behind the eyes. Prothorax transverse, strongly

rounded at the sides, a little wider at the base than at the apex; uneven, closely punctured and

subgranulate, obsoletely canaliculate. Elytra somewhat flattened on the disc, coarsely punctate-striate,

the alternate interstices costate.

Length (excel. rostr.) 4, breadth 2 millim.

Hab. Mexico (Truqut).

Two examples. Larger than 7. solitarius, the rostrum shorter and broader, the

* A character given by Horn for the single N.-American species, 7. asperatus, Boh,, and doubtless

indicative of their fossorial habits,

RHYNCHOPHORA: OTIORHYNCHIN&. 343

eyes larger, the prothorax more uneven and shallowly sulcate, the alternate elytral

interstices costate, the sete much longer.

2. Trachyphleomimus solitarius (p. 177).

Trachyphleus solitarius, Sharp, anted, p. 177.

THAMIRAS, gen. nov.

Rostrum widened outwards, short, longer than the exposed portion of the head, the scrobes lateral, descending

to the lower anterior margin of the eyes; eyes rather large, rounded, coarsely facetted, deeply inserted,

extending for some distance inwards above; antenne with a gradually widened scape, reaching the

tubulate anterior portion of the prothorax, joint 2 of the funiculus shorter than 1, 3-7 short and

moniliform, the club stout and ovate; mandibular scar rather large; mentum small, incompletely

covering the maxille; prothorax constricted towards the apex, the short anterior portion tubulate ;

scutellum minute, narrow ; elytra broad, subtriangular, hollowed at the base, the humeri arcuate and

prominent in front; metasternum short, the episterna very narrowly exposed; ventral segment 2 about

as long as 3 and 4 united, the sutures straight ; legs short; femora clavate, unarmed; tibie strongly

unguiculate, closely ciliate at the apex; tarsi with the lobes of the third joint narrow, the claws free ;

body densely squamose, strongly setose throughout, apterous.

Type, 7’. undulatus.

This genus is based upon a single species from the Los Altos region of Guatemala.

It is related to Trachyphleomimus. ‘The somewhat flattened, subcordate, nodulose

elytra and the subtubulate anterior portion of the prothorax give the insect a peculiar

facies.

1. Thamiras undulatus, sp.u. (Tab. XV. figg. 32, 32a.)

Broad, somewhat flattened above, black, the funiculus and tarsi obscure ferruginous; densely clothed with

dark brown scales (those on the elytral prominences slightly paler), which are partly hidden by an

earthy incrustation, the entire surface (tlle antenne included) also set with rather long, scattered, blunt,

semierect, curved, stout sete. Rostrum slightly depressed at the base (appearing feebly curved when

seen in profile). Prothorax broader than long, gradually, arcuately dilated from the base to the

narrower tubulate apical portion; uneven, densely, finely punctate. Elytra much wider than the

prothorax, somewhat cordate, broadly flattened on the disc anteriorly; punctate-striate, the interstices

towards the sides and apex convex, and here and there nodose or undulate, the eighth with an oblong

prominence below the shoulder. Fifth ventral segment slightly hollowed down the middle towards

the apex. Anterior tibie abruptly bowed inwards towards the apex.

Length (excl. rostr.) 43, breadth 24 millim. (7?)

Hab. GUATEMALA, Totonicapam between 8500 and 10,500 feet (Champion).

One specimen, found in August 1880.

OTIORHYNCHINA ALATA

TANYMECINA.

PANDELETEIUS (p. 185).

Since the remarks on the species of this genus were published (anted, p. 186),

Mr. Schaeffer has kindly given us specimens of his P. cavirostris and ovipennis, from

Brownsville, Texas, and P. robustus from the Huachuca Mts., Arizona, and also

P. rotundicollis, Fall, from Clouderoft, New Mexico. P. cavirostris (as already stated)

344 SUPPLEMENT.

— Polydacrys depressifrons, Boh.; P. robustus * is related to P. hirtipes ; P. ovipennis

has the elytra very little wider than the prothorax at the base, and comes near

P. inflatus, though very much smaller than that insect; P. rotundicoliis has a

6-jointed funiculus, but otherwise generally resembles P. vitticollis. According to

Mitchell and Pierce [Proc. Ent. Soc. Wash. xiii. p. 49 (1911)], P. cavirostris is found

on Khretia elliptica (Boraginez) and Crat@gus (Rosacez).

ENTIMINA.

HYPOPTUS (p. 302).

2. Hypoptus jekeli, sp. n.

Oblong-ovate, shining, black, the legs and antenne piceous or rufo-piceous ; the elytra with several scattered

spots (the two on the fourth interstice—one at the base and the other towards the apex—and the one

at the end of the eighth oblong or elongate) and a marginal stripe, which extends forwards along the

flanks of the prothorax, densely clothed with pale metallic-green scales, the head around the eyes,

the base and apex of the femora, and the under surface in great part, clothed with similarly coloured

scales, the rest of the elytral surface with inconspicuous small dark brown scales. Head with a deep

inter-ocular fovea ; rostrum moderately stout, about as long as the prothorax, curved at the tip, closely

punctate and laterally suicate, without trace of a median carina. Prothorax broader than long, convex,

arcuately dilated at the sides anteriorly, obliquely narrowing in front and behind, feebly constricted

near the apex; densely, finely, uniformly punctate. Scutellum small. Elytra much wider than the

prothorax, convex, acuminate at the apex, with a common, deep, transverse excavation at the base, the

humeri not prominent; coarsely punctate-striate, the interstices feebly convex. Femora strongly

clavate. Tibize set with long bristly hairs.

Length (excl. rostr.) 84, breadth 33 millim. (¢.)

Hab. Mexico (coll. Sommer, in Mus. Oxon.).

One specimen, doing duty for Hypoptus macularis, Jekel, in the Sommer collection,

but very different from the Mexican insect identified under that name by Lacordaire.

The more slender rostrum, the convex, posteriorly narrowed, finely punctured pro-

thorax, and the deep transverse excavation at the base of the elytra readily separate

H. jekeli from the insect here figured under the name H. macularis. The metallic

spots, too, are differently placed and very sharply defined, the rest of the vestiture

being inconspicuous.

PSEUDHYPOPTUS (p. 304).

Pseudhypoptus parcus (p. 304).

Since my remarks on the abraded types of this Mexican species were published,

a good specimen of it (a large female) has been detected in the Sommer collection,

placed under the name Epicerus fallax, Boh. This example is somewhat thickly

clothed with brownish-cinereous scales, which are condensed into a faint spot on each

elytron near the middle and an indeterminate oblique fascia on the outer part of the

disc towards the apex; it has the rostrum sharply carinate.

* The insect sent me by the U.S. Nat. Museum under this name (det. Pierce) (mentioned under

P. vitticollis on p. 202, anted) was wrongly identified. It has a 6-jointed funiculus and comes near

P. rotundicollis.
