INTRODUCTION.

Tue Tribe Longicornia, which occupies nearly the whole of the present volume *, is

equivalent to the family Cerambycide of most modern entomologists, and is one of the

largest of the seventy-two groups into which MM. Lacordaire and Chapuis divided

the Coleoptera, in their great work on the order brought to a completion in 1876.

Compared with the Tribe Geodephaga, it is beyond doubt far more numerously repre-

sented in tropical than in extra-tropical lands, and its species and genera are naturally

multiplied to the highest degree in tropical forests, where woody vegetable growths, to

which the Longicornia are almost exclusively attached in their larval states, are most

numerous and varied. Although their beauty of form and colours has led to their

having been industriously collected, it is evident, from the number of new species

continually arriving from countries supposed to be fairly well explored, that we are yet’

far from possessing even an approximately complete knowledge of the whole product of

Nature in this department. This is partly due to the recondite and, to a great extent,

nocturnal habits of a vast proportion of the species, and the difficulty of the search for

them in dense primeval forests where few clearings offer the necessary openings.

The total number of species described down to 1883, the date of M. Lameere’s

Supplement to the Munich Catalogue, amounted to 8968. In the following pages

1273 species are enumerated or described from the region embraced in the present

work, a number which is probably not more than a third of the total inhabiting

Tropical America, even allowing for the generally-distributed species, which form but

a small proportion of the Longicorn fauna in any one extensive section of the area.

It is probable that an equal number exists in Tropical Asia and in Tropical Africa. In

the Malay Archipelago, Mr. Wallace collected 1046 species, a number which has since

been considerably increased by subsequent explorers. In the Amazons valley I

collected myself 679, a total which will be much augmented when the dense and lofty

forests are partially cleared. Temperate North America must at present number about

700 described species, Crotch in his “‘ Check List,” published in 1874, having recorded

580, and a great number having since been added. Europe, including Russian Asia,

as I gather from Ganglbauer’s “ Bestimmungs-Tabellen” (1884), yields 644 species.

With regard to the relations of the Longicorn fauna of our province to those of

‘adjoining regions of America and other parts of the world, a comparison of the genera

‘with which, in the present imperfect state of our knowledge of the distribution of

species, we have to be content, gives similar results to those pointed out with regard

to the Geodephaga, in the Introduction to the first volume of the Coleoptera of the

present work. It proves even a stronger endemicity in the American, and especially

the Tropical American, Longicorn fauna, than was shown in the case of the Geode-

phaga. The vast majority of the genera, 304 out of a total of 330, are seen to be

exclusively American; 246, or more than two thirds, exclusively Neotropical; and

97 exclusively Central-American. The number of genera common to Central and

Temperate North America is 84, which are composed of the following elements,

viz. :—7 genera widely distributed both in the Western and Eastern Hemispheres; 16

North-temperate genera occurring in both Hemispheres ; 32 American genera of pretty _

general distribution north and south, and 29 genera peculiar and common to North

and Central America. The North-temperate genera occurring in the Central-American

fauna (none of which passes into South America), viz. 16 out of 330, are thus seen to

be relatively much fewer than in the Geodephaga, where the proportion is 16 to 154.

The range southward into our region of these North-temperate forms is further

extremely restricted, for out of the 16, no fewer than 14 stop short at Mexico, and the

two found further south, viz. Leptura in Guatemala, and Pachyta in Costa Rica, are

there represented only by very aberrant species.

The 29 genera common and peculiar to Temperate North America and Central

America form an interesting feature in the fauna, few of them ranging widely beyond

its northern limits. About half of them (15) have close Tropical American affinities,

the other half (14) may be classed as Nearctic forms. Adding these 14 to the

16 North-temperate (Nearctic and Palearctic) genera, we have 30 northern generic

forms of Longicornia in the Central-American fauna which do not extend into South

America; out of the 30, 27 stop short at Mexico, 2 reach no further south than

Guatemala, and the 30th is an aberrant form isolated in Costa Rica. A similar result

is shown if we trace the dispersion southward of the whole of what we may term the

more northerly forms inhabiting Mexico, ¢. e. adding the exclusively Mexican to the

INTRODUCTION. Vv

North-temperate genera, which together made a total of 93. Of these, 74 are confined

to Mexico and Guatemala, and only 5 reach Panama. ‘The essentially Neotropical

forms from South America do not drop off in their range northward in a proportion

at all similar to this; for of 137 South-American genera inhabiting the region

(excluding those of wider distribution) no fewer than 71 reach Mexico and do not pass

beyond ; 16 others reach Guatemala only, and only 50 stop short at Nicaragua.

From this analysis I venture to think that the main conclusions arrived at on a

similar examination of the Geodephaga are confirmed, viz.:—1l, that the Central-

American fauna is essentially Neotropical ; 2, that the northern portion of the region

(Mexico and Guatemala) is not an extension southward of the Neartic Province, but,

3, that it is a remarkably distinct subprovince of the Neotropical fauna.

The species here enumerated as inhabiting our region consist of :—Prionide 60,

Cerambycide 531, Lamiide 682, making a total of 1273 species; of this number

more than half are described as new, viz. Prionide 22, Cerambycide 245, Lamiide 375,

making a total of 642 new species.

The total number of genera is 350; of this number 57 are described as new:—

Prionide 0, Cerambycide 16, Lamiide 41. 493 species are figured on 25 plates. 27°

distinct species are noticed as sp.

%, but not described, owing to want of sufficient

material.

Mr. Champion paid a great deal of attention to these insects, both in Guatemala

and in the State of Panama; he obtained altogether about 600 species. The late

Mr. Belt met with 300 species in Nicaragua, chiefly in the limited district of Chontales.

Order COLEOPTERA.

Tribe LONGICORNIA.

Fam, PRIONIDA.

Subfam. PRIONIN A.

In this subfamily are included the whole of Legions I. & II., and of the latter

Cohortes I. & II. of Lacordaire’s system, resting the definition of the combined subdivi-

sions chiefly on the character of coarsely-faceted eyes. The highly artificial separation

of diverse abnormal forms as a “Legion” equivalent to a natural group of the same

rank, as proposed by Lacordaire, is here avoided. The character of coarsely-faceted

eyes, in Prionide as in other subfamilies of Longicornia, seems very generally asso-

ciated with nocturnal habits and sombre colours.

PARANDRA.

Parandra, Latreille, Gen. Crust. et Ins. iii. p. 28 (1802).

Thirty-five species of this aberrant Longicorn genus were recorded in the Munich

Catalogue (Catalogus Coleopterorum, auctoribus Dr. Gemminger et B. de Harold) in

1873; but many of these have since been shown to be slight varieties or synonyms.

The general form (or facies), colour, and sculpture are remarkably similar in all; and

unless close attention is paid to the dentition of the mandibles in the males and the

accessories of the tarsal claw-joint, it is impossible to distinguish them with accuracy.

Some twenty distinct species, however, are known ; and their distribution is remarkable:

America (Tropical and North) is their metropolis, Western Tropical Africa, the Cape

of Good Hope, the Moluccas, and New Caledonia having each one or two species ; and

one isolated member is found on the borders of the Caspian.

I have compared numerous Central-American examples of this largest of the Pa-

randre with others from Ecuador, Venezuela, and South Brazil, without: finding ‘any

difference of specific value amongst them. Slight differences in strength of punctuation

occur ; but in the more essential characters of the form and dentition of the mandibles, |

and in the outline of the thorax and front edge of the clypeus, all agree closely.

2. Parandra polita. (Tab. I. fig. 3.)

Parandra polita, Say, Journ. Bost. Soc. N. H. i. p. 192 (1835)’.

Parandra cylindrica, Thoms. Mus. Scientif. p. 82 (1860).

‘Hab. Nortsa America, Indianat.—Mexico (Sallé); Guarzmata, Zapote (Champion).

The figure is taken from a well-developed male, with very dark-coloured head, from

Mexico.

Dr. Horn, of Philadelphia, first pointed out the identity of Say’s species with the

well-known cylindrica (so called, although a linear and flat insect). |

8. Parandra scaritoides.

Parandra scaritoides, Thoms. Mus. Scientif. p. 82.

Hab. Nicaraaua, Chontales (Belt, 1 ¢ ).—SoutH AMERICA, Carthagena.

Very closely allied to P. polita, differing chiefly in the more projecting and acute

angles of the orbit of the eyes in the ¢, and by the more conspicuous punctuation

of the surface. The insect is also relatively broader.

4, Parandra angulicollis,

Modice elongata, rufo-ferruginea, passim fortiter (subtus minus crebre) punctata ; antennis thoracis basin attin-

PARANDRA.-~——PSALIDOGNATHUS. 3

Hab. Guaremata, Zapote, Capetillo (Champion); British Honpuras, R. Sarstoon

(Blancaneau); Nicaragua, Chontales (Belt, Janson). |

Having recently examined the type of White’s P. punctata in the British Museum, I

find it different from the Chontales species. It is a female, with, for this genus,

remarkably long antenne. The present species is allied to P. levis (Latr.) of Cuba and

St. Domingo, agreeing with that pretty well in general form, but differing at once in

the position of the first, or lowest, tooth of the mandibles in well-developed males, this

tooth in P. levis being situated far below the other two (which are close together

and terminal), and in P. angulicollis close to the terminal teeth.

The thorax in the male and the majority of the females in P. angulicollis is remarkably

broad and short, uniformly and strongly punctured, and with prominent, acute angles; a

little before the posterior margin it is somewhat strongly narrowed, in a curved line.

The anterior angles in the male project further than they do in P. levis.

P. angulicollis belongs to a group of closely-allied species which appears to be nume-

rous in Tropical America, and which is distinguished by the quadrate and strong median

lobe of the epistome and the single paronychium to the tarsal claw-joint.

ERICHSONIA.

Erichsonia, Westw. Trans. Ent. Soc. v. p. 210 (1849).

One of the principal characters on which Lacordaire relied for separating this curious

little Prionid from Perandra, viz. the absence of paronychia, proves to be untenable, since

true Parandre exist in which there are no paronychia.

1. Erichsonia dentifrons.

Erichsonia dentifrons, Westw. loc. cit. p. 211, t. 22. £21; Lacordaire, Gen. Col. Atlas, t. 81. f. 5.

Hab. Mexico!; British Honpuras, R. Sarstoon (Slancaneau).

PSALIDOGNATHUS.

Psalidognathus, G. R. Gray, Griff. An. K. ii. p. 115 (1882).

This fine genus is peculiar to the Andean region of Tropical America, the forest

region east of La Paz being apparently its southern limit. A species of East Peru.

(P. limenius) descends a little way into the plains of the Upper Amazons; but the

genus does not occur in Guiana or Brazil. We have now to record for the first time

the occurrence of a species in Central America *.

1. Psalidognathus modestus,

Psalidognathus modestus, Fries, Kong]. Vetensk. Acad. Handl. 1833, p. 327, t. 9. f. 1-3?

* The locality “Panama” for P. boucardi and P. batesi, supplied to M. Thomson (Typi Cerambycid.

pp. 7 & 10), is probably incorrect. I have seen numbers of the first-named from the neighbourhood of Medellin,

in. the Cauca valley.

4 LONGICORNIA.

Hab. Costa Rica, Volcan de Irazu (Rogers).—Ecuapor.

A pair (do ¢ ) taken by Rogers on the Volcano of Irazu, in Costa Rica, agree closely

with specimens received from Loja, in Ecuador, which I refer to P. modestus, Fries,

but with much doubt, as the description is not quite satisfactory.

PITHOCLES.

Pithocles, Thoms. Syst. Ceramb. p. 292.

Contains one species only, peculiar to Mexico. The genus is very closely allied

to the following, differing chiefly in the flattened antennal joints of the male.

1. Pithocles’ procerus.

Pithocles procerus, Thoms. Syst. Ceramb. p. 292.

Hab. Mextco (Sallé).

DEROBRACHUS.

Derobrachus, Serv. Ann. Soc. Ent. Fr. 1832, p. 154.

Braderochus (Buq.), Lacord. Genera des Col. viii. p. 74.

This genus is well represented in Central America, and may be cited as one of the

characteristic forms of the region. Two species only are foreign—one (D. brevicollis)

found in the South-eastern States of North America, and the other (D. agyleus) in

“Colombia.”

1. Derobrachus longicornis. (Tab. I. fig. 9.)

8. Derobrachus asperatus. (Tab. I. fig. 43, fig. 5 ¢.)

Derobrachus asperatus, Bates, Entom. Monthly Mag. xiv. p. 274 (1878).

Elongato-oblongus, supra omnino intricato-punctatus, nitidus, niger, elytris maris interdum castaneis; thorace

utrinque equaliter trispinoso ; elytris nullo modo costatis, apice ad suturam spinosis ; antennis ¢ corpore

pedibusque levigatis ; metasterno abbreviato, pedibusque 4 posticis paullo approximatis.

Long. 2 poll. 2lin. 9.

Hab. Guatumata (Boucard).

A species remarkable for the abbreviation of the metasternum and the consequent

approximation of the middle and hind legs—a character which, taken together with

the apterous condition of the females, reveals an affinity with Psalidognathus. In all

essential points, however, the species agrees with Derobrachus. The male is at present

unknown.

MACRODONTIA.

Macrodontia, Serv. Ann. Soc. Ent. Fr. 1832, p. 139.

Six species of this genus have been described from South America, one of which,

the well-known UV. cervicornis, has a wide range, from Rio Janeiro to the Upper Ama-

zons, the others being local. The following is the only one hitherto known to occur

beyond the Isthmus of Panama.

1. Macrodontia dejeani. (Tab. I. fig. 6, ¢.)

Macrodontia dejeantt, Gory, Ann. Soc. Ent. Fr. 1839, p. 127, t. 9.

Hab. Nicaragua, Chontales (Belt).—CoLomsra.

The figure is from a Chontales specimen.

CALLIPOGON.

Callipogon, Serv. Ann. Soc. Ent. Fr. 1832, p. 140.

A genus of narrow range, extending from the tierra caliente of Mexico to Colombia,

Hab. Nicaraeua, Chontales (Belt, Janson).

The figure of Olivier, representing a male, and drawn from Fabrieius's type specimen,

justifies us in considering the original description to refer to the Central-American

form, and not to the Mexican, to which it has been since applied, the two forms being

quite distinct enough to be regarded as species. ‘This is evident on comparing males

of equal development, the Mexican species having mandibles twice the length of those

of the Nicaraguan species, and antenne also relatively much longer. In Nicaragua the —

following interesting variety occurs, apparently frequently, and in company with the type.

The whitish spot and stripe of the elytra are formed of distinct and separate short

hairs, and not felted as in C. lemoinei, although their position is the same as in that

distinct species.

STRONGYLASPIS. ’

Strongylaspis, Thoms. Class. Long. p. 313 (1860).

This small Central-American genus is distinguished from the Old-World Macrotoma

solely by the tumid and roughened scutellum and the strongly arcuated prosternal

process—characters that can only be considered specific, inasmuch as they are variable

in the Old-World genus. The genus might therefore very well be united to Macro-

toma. It is remarkable as being the only form at all nearly related to that well-marked

type of Prionide occurring on the American continent. Macrotoma is distributed

over the warm parts of Africa and Asia, the Mediterranean region, and the islands of

the Indian Ocean and Malayan region. M. Thomson has recently described a Stron-

-gylaspis from Guiana; and M. Chevrolat records the genus from Cuba.

MALLODONOPSIS.

Mallodonopsis, Thoms. Class. Long. p. 317.

This small group is generically distinct from other described American forms, except

Maltlodonoplus and Aplagiognathus, from which it is difficult to distinguish it by

characters of more than specific value. It contains, like its allies, a limited number of

species, confined to North and Central America and the northern parts of South

America. Its affinities seem to be towards genera of the Old World, such as the

Australian Eurynassa, rather than towards Mallodon, with the American species of

which it is nevertheless liable to be confounded. The length and slenderness of the

antennal scape which distinguish the type species (Jf. mewxicanus) are not retained in

species closely allied to it.

Distinguished by its narrow convex form, in which it resembles Aplagiognathus

spinosus more than it does its congener UM. mexicanus. It forms, indeed, a connecting

link between the two genera, the scape being much shorter than in DJallodonopsis,

though retaining the same curved and compressed shape and thus differing from the

short, thick, clavate form of the same joint in Aplagiognathus.

A. spinosus (Newm.) is cited by M. Thomson as the type of his genus Aplagio-

gnathus, which cannot be reunited to Mallodon, as Lacordaire attempted, without

rendering the definition of the latter impracticable. In his later work, ‘ Physis’

(vol. i. p. 90), M. Thomson enumerates eight species (besides two doubtful) as belonging

to his genus, all Central- and North-American. Newman referred the type species to

the Australian genus Cnemoplites, with which it has only a distant connexion.

quarters are America, temperate and tropical—species closely allied to Tropical-American

ones being common insects in Western Africa, and others being recorded from Mada-

gascar and Arabia. The species have all a similar general form and sculpture, and

form a most difficult study ; but trustworthy and definite characters may generally be

found in the mandibles of the males and in the form of the gene, which parts of

structure have been overlooked by almost all describers.

The males of minor development bear the closest possible general resemblance to

the same sex of I. spinibarbe ; but they may be readily distinguished by the form of

the upper edge of the mandibles. In M. spinibarbe this edge describes an upward

curve from the base; whilst in JZ. molarium there is a tubercular prominence at the

base, after which the edge describes a downward curve; the result is to give a much

greater vertical development to the mandible of If. spinibarbe as compared with that of

M. molarium. Inthe males of greater development these peculiarities are still more

strongly pronounced; and I have not seen males of If. spinibarbe with mandibles of

the great length and curve which seem common in M. molarium. In the dentition of

the inner side both species are very similar, presenting a little below the acute apex

two obtuse teeth. There is another but minor specific difference in the form of the

angles of the gene or cheeks below the insertion of the mandibles: in both species

the edge is slightly sinuated, and the angle forms a projection visible when the head

of the insect is viewed from above; but in VW. molarium the angle is blunt, whilst in

M. spinibarbe it is developed into a distinct stout spine.

Dr. Gemminger changed the name in consequence of the prior use of gnatho for a

has since proved not to be a Mallodon, the two genera are so closely allied that perhaps

it is advisable to retain the correction, in order to avoid possible confusion.

The base of the thorax is of similar form to that of all the allied species; but the

sides, from the lateral spine forward, converge somewhat unevenly to the anterior

angles, which are close to the neck. In some examples of the female the anterior

narrowing of the thorax is more abrupt and occurs nearer the front angles. The

antenne in what appear to be the males have the third and fourth joints more dilated

and more oblong than in what appear to be the females, in which the third joint and

following are pf the same subovate form, the third only being conspicuously longer

than the rest. The colour of the species is extremely variable.

Hab. Costa Rica, Volcan de Irazu, 6000-7000 feet (Rogers).

Differs from its congeners somewhat in facies, the difference being due chiefly to the

form of its thorax, the lateral spine of which is exactly median, very long and sharp and

nearly straight. With this is combined the relatively small size of the thorax, not only

as to its length, but also its breadth, the width (exclusive of the spines) being only half

that of the elytra. The antenne are very long, about a fourth longer than the body ; and

none of the joints make any approach to the oval form so frequent in the genus. The

opaque joints are very minutely striated.

Section A of his “‘ Cérambycides vrais sylvains.” Thus conceived it embraces a prodi-

gious number and diversity of generic forms, which no doubt contain the elements of

several subfamilies equivalent to the “ Prionine.” A thorough revision, founded on all

the material contained in the large public and private collections of Europe, would be

required to settle the limits of the larger groups of genera in question.

Notwithstanding the very different facies, the shortness of the antenne, and other

necting link between these genera.

In general form the insect for which this genus is proposed resembles so strongly a

Prionid of the genera allied to Macrotoma that it would be certainly placed among them

if attention were not given to its essential characters; the most decisive of which are

_ the simple rounded sides of the thorax and the relative shortness of the sockets of the

haunches of the anterior legs. The distinctly articulated labrum is a further point of

distinction from the Prionide. From the genera to which it is nearest allied (Spatho-

pygus, Diploschema, &c.) it is distinguished by the absence of prosternal process and the

exserted fore coxe. |

The unique specimen is probably a female, judging from the shortness of the antennee

and the slenderness of the legs; the apical segment of the abdomen, however, is of the

form we usually find distinctive of the male, the plates, both ventral and dorsal, being

sinuated in the middle. The pubescence of the head, thorax, and antenne is erect and

not so close as to obscure the slight gloss of the integument. The antenne are punc-

tured throughout, the scape only densely. The elytra are of a light tawny-brown colour,

darker and castaneous towards the base.

In general form and most of the essential characters this new genus agrees with

Pantomatlus; but it differs from that and all genera of the Hesperophanina group by

its sulcate antenne. The sulci, however, are not distinct except on the third joint and

in the males, in which sex this joint is also thicker from base to apex than the remain-

ing joints. There isa faint raised line on the sides of several of the joints following

the third, which indicates the margin of an obsolete groove. The femora, especially in

the males, are much thicker than in Pantomallus, Chion, and other allied genera, resem-

bling the robust form of the same members in Phacodes. In the markings of the

elytra the genus bears no resemblance to Pantomallus, reminding one rather of Hespe-

rophanes.

The genus Osmidus of Leconte, found in Lower California, must be very closely allied

to the present one, judging from the description. It wants, however, the antennal

grooves.

The sparsely scattered shining punctures of the elytra are obliquely impressed, and

each bears a stiff bristle. The antenne are altogether more robust in the male than in

the female; and the joints from the third to the eleventh are almost exactly equal in

length—this latter character distinguishing well the genus from Brothylus (Leconte),

the markings of which appear to be very similar to those of our species. The eleventh

joint is curved, and bears no trace of appendage or false twelfth joint; and all the joints

in both sexes are rather closely and finely ciliated beneath.

EBURIA.

Eburia, Serv. Aun. Soc. Ent. Fr. 1834, p. 8.

About forty species of this elegant and exclusively American genus have been

described. They are generally very local, and occur in temperate as well as in tropical

latitudes; but none, I believe, has been recorded from so far north as Canada, or so far

south as Chili. Some are found in the West Indies; and one species is described from

the Galapagos. The larve feed in the interior of large decaying forest-trees. The

genus is limited here to those species which have simple antenne, those with sharply-

grooved joints forming the genus Kburodacrys.

Nearly as robust in form as L. stigmatica, similar in colour but a little redder,

distinguished from this and allied species by the very large confluent punctures of the

thorax and the rounded apices of the elytra. The ivory-like lines are elongated, being

similar in relative length to those of Hburodacrys havanensis ; the exterior median lineole

is far from attaining the great length it does in H. macrotenia.

Agrees in general form with FE. pedestris, but is distinguished at once by the long

linear form of the ivory-like spots of the elytra and also by the five discoidal tubercles

of the thorax. These tubercles are more conspicuous than in other Hburie—the

ordinary three anterior ones being large, elevated, and glossy, and supplemented by the

hinder elevations of the disk on each side, which are a little more raised than usual

and coloured black.

Hab. GuateMaa, Capetillo ( Champion).

A fine species, of a light tawny-brown hue, densely clothed with fine ashy pubescence,

and bearing a striking resemblance at first sight to Pantomallus fuligineus, from which

its spinose hinder femora at once distinguish it. The ivory-like spots of the elytra

are larger, broader, and each pair closer together than in Pantomallus fuligineus,

and are much narrower and more linear than those in Hburia pedestris. The exterior

spot of the basal pair is relatively much longer than the corresponding spot in L.

pedestris; and the corresponding spot in the hinder pair is double the length of the

inner spot. The thorax is sculptured almost as in L. pedestris, being faintly and not

densely roughened with vermiculate ruge.

8. Eburia brevispinis. |

E. stigmati et duvalit proxime affinis, rufescenti-fusca, erecte pilosa, pedibus antennisque fulvo-rufis, subtiliter

riore paullum longius spinoso; thorace vage rugoso, vix insequali, spinis lateralibus brevissimis obtusis,

tuberculo antico-laterali et duobus dorsalibus nigris nitidis; femoribus quatuor posticis breviter uni-

Spinosis.

Long. 10 lin. GQ.

Hab. Muxico, Soledad, Jalapa (Hége).

Very similar in facies to the West-Indian £. stigma and EL. duvalii, but differing

from both in the shorter femoral spines (the exterior one being extremely short), and

from F. duvalii in the elytral and thoracic spines being also much shorter. ‘The colour

is also more rufescent (approaching H. pedestris) than in either species. In the punc-

tation of the elytra the mixture of rather large punctures with the minuter sculpture

is notable, each puncture giving rise to a long erect stiff hair, which features are absent

from the allied species. The ivory-like spots of the elytra are surrounded with black,

which colour is lengthened moderately before and behind, the streak from the exterior

median line nearly reaching the corresponding basal line.

In the male the thorax has a short dorsal black line in addition to the tubercles.

9. Eburia egrota.

Subeylindrica, gracilis, pallide fulva, opaca, breviter erecte pilosa; thorace angusto, vage punctato-rugoso,

tuberculis duobus disci nigris nitidis, spinis lateralibus post medium fulvis; elytris apice breviter sinuato-

truncatis, angulo exteriore spinoso, suturali acuto, supra creberrime punctulatis, utrinque maculis subelon-

gatis quatuor geminatis eburneis (basalibus equalibus, medianis longioribus) contiguis ; femoribus quatuor

Long. 73 lin. 9.

22 * LONGICORNTA.

Hab. Mexico, Plan del Rio (Hége).

A small and slender species for this genus, resembling the typical Eburodacrys. A

distinguishing character is the absence of antero-lateral tubercles from the thorax,

although the lateral spine is well-developed, conical, and acute. ‘The usual exterior

spines of the hinder femora are quite obsolete. The geminated eburneous spots are

closely contiguous, both basal and median pairs, and are narrowly margined with brown.

10. Eburia laticollis.

Obscure rufescenti-fusca, subtilissime pubescens et erecte pilosa; antennis scapo (¢) brevi, mox a basi in-

crassato; thorace magno, subrotundato, spinis lateralibus minutissimis,.tuberculis duobus disci solum

nigris politis ; elytris apice breviter bispinosis, supra crebre punctulatis punctisque majoribus intermixtis,

lineolis brevibus utrinque quatuor geminatis sed haud contiguis, duabus basalibus brevissimis interiore

Hab. Muxico (Hegewisch).

Although agreeing in the sculpture and clothing of the elytra with L. brevispinis,

from Elaphidion (and Hypermallus), the following characters :—form more robust ; epi-

sterna of the mesothorax wider in front and gradually narrowed behind ; prothorax wider,

more coarsely punctured in the ? than in the d; and the antenne with distinct sensi-

tive spaces, commencing with the fourth joint. The group seems a natural one; five

species inhabiting the southern parts of the United States belong to it, one of which

extends its range to Mexico.

ELAPHIDION.

Elaphidion, Serv. Ann. Soc. Ent. Fr. 1834, p. 66; Lacord. Gen. Col. viii. p. 300.

Lacordaire restricted the old genus Elaphidion to the limited number of species in

which the pro- and mesosterna have their opposing faces vertical or nearly so, and the

posterior femora spined, instituting a genus Hypermalius for the remainder. The

separation has not proved satisfactory; and Dr. Leconte, in his important work on the

North-American Longicornia (Smithson. Miscell. Coll. part ii. 1873), has recombined

Hypermallus with the more typical forms. We here retain the genera as characterized

by the author of the ‘Genera.’ laphidion in its restricted sense contains four or five

species, peculiar to the West Indies and North and Central America.

Elaphidion (pars), Newman, White, Leconte.

The range of this genus is much wider than that of Elaphidion, although still con-

fined to the American continent. The majority of the species occur in the south tem-

perate latitudes of North America and in the West Indies; but some are found in

Brazil, and as far south as Parand and Buenos Ayres. About fifty have been described ;

but many of them probably do not strictly belong to the genus.

H. incerto (Newm.) similis, at differt thorace magis convexo, dorsoque fere integro. Elongatus, fuscus, antennis

pedibusque fusco-rufescentibus, fusco breviter pilosus, thorace elytrisque maculatim cinereo-tomentosis ;

guttisque utrinque politis; scutello cinereo; elytris recte truncatis, angulo suturali breviter spinoso,

supra confertim punctatis, apicem versus punctulatis ; metathoracis episternis fere parallelis.

Long. 8 lin.

Hab. Mexico, Paso del Macho (Hége).

Closely resembling H. incertus (Newm.) in form and colouring, but distinguished at

once by the absence of dorsal callosities from the thorax, which is more rounded

on the sides and more evenly convex, the surface being varied only by a short polished

streak in the middle of the dorsal line and a small spot or two on each side of the

disk, scarcely visible in some specimens. The tawny ashy tomentose spots are

scattered over the elytra, being more confluent near the base and on the sides than

towards the apex. The apex itself is spined only at the sutural angle of the straight

truncature, the exterior angle being simply acute and not spiniform as in H. incertus.

2. Hypermallus undulatus.

Fere cylindricus, atro-fuscus, cinereo incumbenti-pubescens, thorace guttis, scutello, elytris fascia mediana

undulata maculaque utrinque ante apicem canis; thorace oblongo, lateribus ante medium rotundatis, toto

femoribusque crebre punctatis; antennis articulis 3°-4™ apice breviter spinosis.

Hab. Mexico, Trapiche (Hége).

A very distinct species, resembling the West-Indian H. transversus (White) in the

regular alveolate sculpture of the pronotum, without trace of inequality or callosities ;

but the prothorax is much narrower and more elongate than in H. ¢ransversus, and the

species differs in the less spinose antenne and apex of the elytra. The episterna of the

mesothorax gradually but slightly taper from base to apex; they are, however, narrow

throughout and not wide at the base as in Romaleum.

maculatim vestitus; thorace oblongo, dorso callis elevatis politis, interstitiis punctulatis, tomento cinereo

vittas laterales formante ; elytris coriaceis et passim punctulatis, apice fere integris, juxta suturam leviter

emarginatis.

Long. 94 lin.

Hab. Honpvras, river Sarstoon (Blancaneau).

Resembles Elaphidion irroratum, and is liable to be mistaken for that species, from

which it is readily distinguishable by the absence of spines at the apex of the elytra.

The ashy-white patches of tomentum are also differently arranged, being scattered

irregularly over the elytra (mostly on the sides), instead of being concentrated in large

patches. The thorax has polished elevations on the sides as well as on the disk, the

depressed interstices being minutely (instead of coarsely) punctured. A distinguishing

character is the small size of the spines at the apex of the third to the fifth antennal

joints. The nearly rounded apices of the elytra, the facies, and faintly impressed tibial

carine are features which separate this species from all other known Trichophori. It

seems, in fact, to connect Trichophorus with Hypermallus, and thus bridge over the:

differences between two of Lacordaire’s groupes, viz. Phoracanthides and Sphérionides.

Hab. Nicaraevua, Chontales (Belt).

This species is remarkable for the extreme narrowness of the metathoracic episterna,

which are covered by the lateral rim of the elytra, except for a small portion near

their base. With this structural peculiarity are associated tightly-closed middle

acetabula and a cylindrical smooth thorax. In these characters it approaches the

genus Apospherion, Bates (Trans. Ent. Soc. 1870, p. 275), from which it differs again —

by the obsolete grooves and carinz of the antenne, which in Apospherion are. very

highly developed. The similarity of the sternal structure, however, seems to me to

outweigh the differences in the antenne; and I would propose to include Nephalius

The genus is here restricted to the species closely allied to Serville’s type WU. glauca

of South Brazil. Lacordaire (Gen. des Col. viii. p. 320) introduced alien elements

into it. In its restricted limits it comprehends only some half dozen species, all

Tropical-American, of which the following only is known from so far north as Central

America :—

PSYRASSA.

Psyrassa, Pascoe, Ann. & Mag. Nat. Hist. ser. 3, xviii. p. 481.

A genus limited to two or three species, inhabiting Central and North America.

The spine of the third antennal joint is remarkably long; and this seems to be a good

generic character. The carine of the antenne are inconspicuous, being placed on the

side of the joints, as viewed from above. |

More elongate than P. basicornis, and much more sparsely punctured, both on the

thorax and on the basal portion of the elytra. The colour is uniform tawny-chestnut,

with the antenne, legs, and palpi paler. The angles of the elytral truncature are

rather more produced than in P. bastcornis, but are not spiniform as in P. unicolor

(Haldem.), being broader or dentiform.

IRONEUS.—HARUSPEX. 29

IRONEUS.

Lroneus, Bates, Trans. Ent. Soc. 1872, p. 178.

Two species, both from Central America, are known of this genus. The second,

described below, will be seen to depart from the type in some of its characters.

1. Ironeus duplex. (Tab. IV. fig. 3.)

Lroneus duplex, Bates, loc. cit. p. 179.

Hab. Nicaragua, Chontales (Belt).

2. Ironeus pulcher. (Tab. IV. fig. 13.)

Elongatus, modice convexus, niger, erecte pubescens, capite, thorace, scapo et femoribus rufis ; elytris dense

cano-tomentosis, utrinque lineis tribus nigris nitidis, quarum mediana latior.

Long. 53 lin.

Hab. Nicaracua, Chontales (Janson).

Differs from L. duplex in the eyes being rather more prominent and more coarsely

faceted. Although these differences are important, the close similarity of form in all

other respects renders it unadvisable to separate the species generically. The antenne

in the male are very similar in length and structure to those of the same sex in [. duplezx.

The same may be said of the subcylindrical unarmed thorax, the dorsal surface of

which is slightly uneven in both species, faintly transverse-strigose in J. pulcher, and

marked with scattered punctures in J. duplex. The elytra differ greatly in being clothed

with hoary tomentum, having the suture and three narrow vitte on each side (the

middle one broadest and elevated) naked and of the shining black colour of the inte-

gument; their apices are briefly truncated, with the external angle slightly produced.

The legs are of the same proportions and structure, and of the same colour (é. é. black,

with the femora red). The head, thorax above and beneath, and the antennal scape

are bright red; the meso- and metasternum and abdomen are black.

. MILTESTHUS.

30 LONGICORNIA.

1. Haruspex chontalensis. (Tab. 1V. fig. 12.)

Sublinearis, castaneo-rufus, supra opacus, pilis longis erectis vestitus ; antennis quam corpus multo longi-

oribus ; elytris apice late truncatis, angulis exterioribus longe spinosis.

Long. 4 lin. .

Hab. Nicazaaua, Chontales (Janson).

The head and thorax are darker than the rest of the body, and very coarsely but

superficially subreticulate-punctate, the latter being cylindrical, with a broad transverse

sulcus near the base. The elytra are nearly parallel-sided, broadly truncated at the

apex, with the sutural angle rectangular and the external one produced into a long

sharp spine; the surface is covered with large punctures arranged closely in rows.

The legs are long, scarcely compressed, with strongly clavate femora. Beneath, the

pro-, mesothorax, and anterior part of the metathorax are opaque, like the upper sur-

face ; but the posterior part of the metathorax, underside of the femora, and abdomen

are highly polished.

HEXOPLON.

Six or seven species of this elegant genus of Cerambycide are known, all Tropical-.

American. It is distinguished from Gnomidolon solely by the long spine at the internal .

apex of the middle tibie, a character which appears to be sufficiently constant to justify

the retention of the genus. |

Eighty species of the restricted genus Ididion are recorded in the Munich Catalogue.

The range is a little more extended than that of Hexoplon, Octoplon, and other dis-

memberments of this very numerous and characteristic American group of Cerambycide,

IBIDION. 31

some occurring in the Argentine Republic and as far south as Chili. The thighs are

more abruptly clavate than in Hexoplon and Octoplon, and are unarmed at their apices.

In many species the carine of the antennal joints and hind tibie are scarcely

perceptible.

The habits of the Zbidia and allies are nocturnal, the perfect insects being found in

the daytime motionless, on trees, generally concealed in the folds of leaves. They

abound most in the scanty woodlands on the margins of campo and savanna districts,

_ the continuous luxuriant forests of humid lowlands having fewer species. They are

not, as a rule, widely distributed; and as each limited area throughout Tropical

America has many peculiar to it, the number of species is prodigious, and the number

of individuals relatively small. On this account, and owing to their recondite habits,

they are not common in collections. Few, however, have hitherto been recorded from

Central America. |

Hab. Guatemaa, Zapote (Champion).

Almost identical in the peculiar markings of the elytra with 1. quadriguttatum

(White), which is a Heterachthes in its unridged antennal joints, whilst the present

species has well-developed carine. The short, oblique, deep-black streaks of the elytra

are rather closer together than in J. 4-gut¢atum, the anterior being a little before and

the posterior a little behind the middle; they touch neither the lateral margin nor the

suture, from which latter they are widely distant; and the anterior streak (directed

obliquely backwards from the margin towards the suture) is rather more slanting than

the posterior streak, which is directed a little forward from the margin towards the

suture; both are margined with very pale yellow, as in L. 4-guttatum; and the space

between the pair on each elytron is also pale yellow. The antenne are very short for

an Ibidion, if, as I suspect from the thickened third and fourth joints, the single

specimen before me is a male.

This species was included in my paper (Trans. Ent. Soc. 1872) among the Longicornia

justly referred to it, as, inter alia, they all far surpass the size (95 millims.) given by

M. Thomson in his diagnosis of I. mexicanum. The determination of the Guatemalan

specimens is also doubtful.

A Heterachthes according to Lacordaire’s definition. In form and proportions of

body, as well as in colour and markings, similar to J. phoracanthoides (White). It is,

however, shorter ; and the apices of the elytra are unarmed. The dark-brown colouring

of the elytra occupies more than one half the surface, leaving the base (to a small

extent) and a large apical area of the chestnut-red ground-colour. Across the dark-

brown central area lie two broadish tawny-white slightly oblique belts, which are much

broader towards the sides than towards the suture, which they nearly touch. The

coarse but not very dense punctuation becomes obsolete near the apex.

DISTENIA.

Distenia, Serv. Encyl. Méth. x. 1825, p. 485.

This genus, with several others very closely allied to it, was marked off by Lacordaire

as a separate “ Division” of Section B of the first ‘“‘ Cohorte” of Cérambycides, owing

to a peculiarity in the insertion of the antenne, which are placed more forward on the

head, in front of the eyes and near the mandibles. ‘This peculiarity is distinctive of

the Prionide family, but is not observed in any of the Cerambycide, to which the

Distenie belong in all other respects. It must be borne in mind, however, that a

large number of the Lepturina show an approximation to this structure, and (what is

of much importance in estimating the affinities of these difficult forms) great vacillation

in the position of the antenne. Since Lacordaire wrote, several aberrant forms of

Lepturina which approach the Distenie in many respects have been discovered in

Madagascar; and it is probable the views of Latreille and Serville were more correct,

and that Distenia &c. are really allied to the Lepturina—in which case their position

would be between the subfamily Cerambycine and the Lepturine group, where I now

place them. The degree of coarseness in the faceting of the eyes is variable in the

Distenia group, as it is in those genera of Lepturina to which the Disteni@ are nearest

allied in other respects. In most of the large American species the eyes are coarsely

faceted. In Lacordaire’s system the Disteniw were relegated to the end of the family,

without any indication of their affinities.

The Distenie are widely distributed over the warmer parts of the globe; they are

found in North and South America, Africa, India, the Malay archipelago, and Japan.

None have yet been detected in Europe or Australia. They appear to be mostly

nocturnal in their habits. .

The single example sent home by Mr. Champion agrees very well with the description

of Lacordaire, who was ignorant of the locality of the specimen he described. It

appears to be only a local form of D. pilatei, varying from the type in the brassy polish

of the glabrous stripe bordering the suture and the greater prominence of the thoracic

tubercles.

The examination of further examples has justified the suspicion expressed in re-

from the D. rufipes of Colombia. The sculpture of the elytra is constantly different,

the confused punctuation being closer and uninterrupted, except by the few lines of

more regular punctures. The dull tawny-red colour of the antenne (except the basal

two joints and base of the third) is also a constant character.

probably generically different from Distenia; but until both sexes are known it would

be unsafe to found a genus upon it. The vitte of the elytra are:—one continuous,

parallel and very near the suture, diverging from it near the scutellum in the direction

of the shoulders ; and one marginal, interrupted and irregular in width, passing round

the apex and joining the sutural stripe.

broader behind and more strongly narrowed in front, and the mesosternal process is

much more elevated and advanced. In its rather obscure brassy colour, sometimes

inclining to greenish or slate-colour, and especially in the uniform and rather dense

clothing of short ash-coloured hairs, it is very distinct from G. cyanipennis.

2. Gaurotes ochropus.

G. donacioidi proxime affinis, at differt pedibus antennisque fulvo-rufis. Auneo-fusca, pilis brevibus cinereis,

subtus densius vestita ; antennis (articulis basalibus fuscis exceptis), femoribus (genibus fuscis exceptis)

tibiisque basi fulvo-rufis ; thorace nitido, minus crebre punctato, linea dorsali levi; elytris trigonis, apice

truncatis, angulo suturali acuto, exteriore spinoso, dorso crebre punctulatis.

Long. 44 lin.

Hab. Mexico (Hége).

38 LONGICORNIA.

Abundantly distinct from G. donacioides, independently of the colour of the legs and

antennee, by the less densely punctured and more shining surface of the head and

thorax, by the less produced sutural angle of the elytral truncature, and by the more

compact ashy pubescence of the under surface of the body.

LEPTURA.

Leptura, Linneus, Syst. Nat. 1. p. 397 (1758).

A numerous genus, highly characteristic of the faunas of north temperate latitudes

and alpine zones in both the eastern and western hemispheres. About 170 species have

been described; but none has hitherto been recorded from the southern hemisphere,

or from so low a latitude in America as the following Mexican representative :—

1. Leptura aliena.

Elongata, precipue elytris longis et parallelis, apice rotundatis; nigra, subtus nitida, supra sericeo-subopaca, .

dense breviter erecte pilosa; capite alveolato-punctato, genis paullo post oculos subangulatis ibique collo

subito constricto; antennis filiformibus, subgracilibus; thorace ut in genere Anoplodera subcylindrico,

postice vix dilatato angulis haud productis, lateribus modice rotundatis, dorso modice sequaliter convexo,

punctulato; elytris elongatis et subplanatis, subtilissime discrete et eequaliter punctulatis. ;

Long. 5-7 lin.

Hab. Mexico, near the capital (FJohr).

A species distinct from all others by its general form (elongate, parallel-sided) and

its facies (due to the dull sericeous elytra and their flattened surface). Its affinities

seem to be in the direction of the genus Anoplodera, not admitted as distinct from

Leptura by Lacordaire.

NEOLEPTURA.

Neoleptura, Thoms. Class. Long. p. 153; Lacord. Gen. Col. viii. p. 450.

The following is the only described species :—

OPHISTOMIS.

Ophistomis, Thoms. Archiv. Ent. i. p. 319; Lacord. Gen. Col. viii. p. 451.

According to Lacordaire this genus is restricted to Tropical America; but as its only

constant distinguishing character rests on the long and narrow rostrum-like prolon-

gation of the head, and this is exhibited to some extent by species of Strangalia from

China and Japan, very much importance cannot be attached to this fact of geographical

distribution. About fifteen species are known from Tropical America.

_ One example only is yet known of this species; the following nearly allied form,

however, is clearly distinguishable from it :—

3. Ophistomis emaciata.

Angusta, gracilis, sparsim decumbenti-setosa ; capite nigro; antennis nigris, articulis 6°-10™ incrassatis flavis ;

thorace angusto, antice gradatim attenuato, dorso sparsim punctato, nigro nitido, macula basali vittaque

lata laterali flavis, angulis posticis paullo productis ; elytris flavis, sutura (pone scutellum latius) maculisque

utrinque lateralibus versus basin nigris; corpore subtus, prosterno, metasterno lateribus ventreque apice

nigris ; pedibus piceis, tibiis femoribusque basi fulvis.

Long. 7 lin. 9.

Hab. Costa Rica (Rogers).

One example only, of the same sex as the specimen above mentioned of O. belti. Of

slender form even for this genus, the thorax especially being very narrow and gradually

tapering towards the head, strongly bisinuated at the base, with the posterior angles

only moderately projecting. The antenne are nearly of the same form and colour as

in O. picticornis 2; the fulvous-yellow colour, however, is more developed, extending

from the tip of the fifth to the base of the tenth joints. The elytra are sparsely punc-

tulated, very obliquely truncated at the apex, narrow between the shoulders, and

gradually tapering behind; they are yellow, with the suture narrowly dusky, the dark

colour expanding for a short space behind the scutellum; the other black spots are

entirely marginal and near the base, the spots nearest the base being two in number,

elongated, and side by side; a third spot lies a little before the middle of the elytra;

the edge of the elytral epipleure also has a dusky line.

sulcus, giving it a gibbous appearance when viewed in profile. Both species agree

also in the smoothness and opalescent gloss of the thoracic surface; its colour, how-

ever, is different, the red occupying the basal half in O. rostrata, and forming three

longitudinal stripes in O. levicollis. The base of the elytra is broad and straight, but

oblique just before the angular shoulders. The epipleure are vertical and rather

sharply separated from the plane dorsal surface.

6. Ophistomis flavirostris.

Gracilis, nigra, elytris parallelis griseo-setosis; capite infra, fronte, thorace angulis posticis femoribusque

basi flavis; thorace campanuliformi, convexo, subtiliter ruguloso; elytris creberrime punctulatis, humeris

vittula rufescente.

Long. 44 lin.

Hab. GuateMata, Zapote (Champion).

A small parallel-sided species, with ashy-pubescent elytra. In colours it resembles

O. albicollis (Pascoe), from which it differs widely in form and sculpture. The crown

and occiput behind, and the mouth and its borders in front, are black; all the rest of

the head is bright yellow. ‘The antenne are black. The thorax is wide behind and

narrowed in curved lines to the anterior sulcus, the surface being a little less convex

than in 0. levicollis, minutely sculptured, and opaque; the yellow colour at the

posterior angles forms a large spot reaching halfway up the side and on the flank of

the thorax. The elytra are very closely punctured, and have a faint reddish streak

proceeding from each shoulder. The underside of the body is ashy black, the legs

black, with the basal halves of the femora and the base of the four hinder tarsi yellow.

OXYCOLEUS.

Ozycoleus, Lacordaire, Gen. Col. viii. p. 484.

A curious genus of the Molorchina group, with abbreviated triangular elytra. It is

allied to the European and North-American Callimoxys, and is scarcely distinguishable

from Merioneda (Pascoe) of the Malay Archipelago and Malacca. Stenoptrellus

(Bates) from the Amazons, published a year after Oxycoleus, is evidently congeneric.

Three or four species of true Khinotragi have been described, all from Tropical

South America. The following is the first made known from Central America; and

it is curious that it resembles closely a South-Brazilian species.

1. Rhinotragus longicollis. |

Hab. Nicaragua, Chontales (Belt).

Although agreeing with Guérin’s description of his 2. apicalis, from Bolivia, as far

as it goes, I doubt the probability of this being the same as his species, as Guérin makes

no allusion to the distinguishing character afforded by the elongated and rather narrow

thorax. The above description will suffice to distinguish FR. longicollis from R.

dorsiger, and probably from &. apicalis, if as I suspect, the thorax is of similar form

in these two southern species.

Belongs to the subgenus Eclipta of the monograph of Rhinotragine (Ann. & Mag.

remarkably elongate and narrow, and bears much resemblance to that of Odontocera

gracilis (Klug), with which the species agrees in colours and markings. The absence .

of vitreous spaces on the elytra (a distinguishing character of the genus Odontocera),

the smaller size of the insect, and the uniform reticulate-punctate surface of the cylin-

drical thorax at once enable it to be recognized.

Much less elongated than O. sanguinolenta, and similar in form and colours to

are nearly of the same form (relatively shorter) as in O. gracilis. Fach elytron forms,

after the middle, a linear parallel-sided blade, slightly flexuous, the two blades being

more distant from each other near the middle than at the apex.

Hab. Mexico (Hegewitsch).

Rather larger and more robust than S. eger (the described example of which is a

male), and differing from it by the smooth, glassy surface of the disks of the elytra,

which are also relatively narrower and somewhat dehiscent after the middle. In these

characters the species points to the relationship of the genus with Odontocera, which

in S. wger was not indicated. The structure of the antenne and the atrophy of the

prosternal process afford abundant characters for the distinction of the genus, which is,

besides, totally different from Odontocera in facies. —

Lacordaire, Gen. Col. ix. p. 15.

As restricted by Serville and Lacordaire this fine genus includes only American and

African species. In all the hind femora are linear and simple, ¢. e. free from notch or

prominence beneath. The only definite character which I can discover separating it

from the Europeo-Asiatic Aromia (which includes the common musk-beetle of the

British Islands) is the clavate and pedunculate middle femora. The numerous group

Chloridolum, abundant in Tropical Asia and its islands, approaches it in this respect ;

but Chloridolum is marked off as a distinct group by the more slender form of the

species and the proportions of the second and third antennal joints, the two being about

equal in length, whilst in Callichroma the third is constantly the longer. About fifty

species are known, twenty of which are West- and South-African.

The American species are sometimes found very abundantly on flowers.

Fourteen species, all Mexican, are included by Chevrolat in this genus. It is doubtful,

however, if they all really belong to it; 7. hartwegi at any rate must be separated, as

it agrees neither in facies nor structure with the typical species. Trichoxys differs

structurally from Clytus, as restricted by Chevrolat and Lacordaire (Gen. Col. ix. p. 67),

in the depressed suture and longitudinal carine of the elytra, the prominence and ver-

tical front edge of the mesosternum, and the stronger bristles of the basal joints of the

antenne. In their general form and markings, moreover, the species are very different

both from Clytus and all other genera of the group, and form a natural assemblage of

forms, to which their circumscribed area of distribution gives additional definiteness.

In 7. hartwegi the third to sixth antennal joints have a strong spine at the apex.

This alone is perhaps not a sufficient warrant for generic separation, unless we are pre-

pared to treat Cyllene nebulosa and antennata in like manner, which differ from all

the other species at present included in the same genus by their spinose antenne. But

Trichoxys hartwegi differs also in the form of the antenne and in that of the thorax and

legs, especially the femora.

This pretty little species is especially ill-placed in Anthoboscus (=Clytanthus), to

which Chevrolat referred it. The depressed sutural area of the elytra, bounded by a.

longitudinal carina, shows that its position is near Cyllene or Trichorys. In colours it

has no resemblance to any other species, except perhaps Cyllene chara of Say. ‘The

mesosternum, although not prominent and vertical, as in the typical TZrichoxys, is

decidedly convex. It may be regarded as an aberrant or degraded form of this genus.

several succeeding joints red, their under surface furnished with the usual stiff bristles.

The thorax is nearly globular, but strongly constricted at the base. The elytra are

elongate-trigonal, with the usual depressed suture, bounded bya longitudinal carina on

each side, the apex being simply angular and not spinose; the apical third of the

surface, suture, and lateral margins are blackish, the rest of the surface reddish tawny,

the dusky suture widening near the scutellum, and a small pale ashy spot lying near

the suture on each side a little before the apex. The legs, with the exception of the

tarsi, are bright red. The mesosternum is very convex, but not vertical in front as in

Trichorys. 'The antenne (¢) are of equal thickness to the apex, and about two thirds

the length of the body. The hind femora are short and gradually thickened.

Lacordaire would not venture to extend the limits of this genus beyond the few

European and Mediterranean species contemplated by its founder. But Clytus

speciosus, Say, of North America, the type of Dr. Leconte’s genus (lycobius, is

perfectly congeneric with the European Plagionotus detritus, and species of imilar

structure of antenne and legs and form of thorax and sternal processes occur in

Mexico. Other species have been discovered in Eastern Siberia; the genus has

therefore a wide range in the northern hemisphere. As in other modern genera of

Clytini, the characters strongly marked in the extreme forms (which are nearly always

chosen as the types) rapidly dégenerate from species to species until all distinction

from allied genera disappears. Thus Plagionotus siculus is scarcely distinguishable

generically from Clytus floralis; similar blending of generic characters occurs in the

Mexican fauna.

Lacordaire did not admit this genus as distinct from Neoclytus. It seems, however,

quite as well defined as most of the other genera of the Clytini group adopted by him

and other authors. To the slender form of the hind legs, especially the femora, and

the elongated and subvertical forehead, are added a distinct style of coloration and

markings, and a more circumscribed and compact area of distribution. ‘The genus is

peculiar to Tropical America, and contains about twenty known species. Only one is

at present known from so far north as Mexico; and none have been recorded from

beyond the southern limits of Brazil.

One of Belt’s examples forms a variety in which the bright yellow spots of the

elytra are much more extended than in the type, reducing the width of the black

ground-colour. The middle sutural spot is prolonged and angular behind as in front,

i. e. rhomboidal in shape instead of triangular.

The species, according to the description, seems to be closely allied to the Colombian

Mecometopus amaryllis (Chevr.), which differs in the more slender antenne and the

red colour of the anterior legs. :

Hab. Mexico, Cordova (Sailé!); Nicaraeva, Chontales (Belt?).

A species remarkable for the ridge-like elevations of the base of the elytra (two on

each side) and the compressed and dilated hind tibiz. The head is precisely that of a

typical Mecometopus ; and there are no grounds whatever for referring the species to

the genus Tillomorpha, as Chevrolat has done. Mecometopus polygenus has also

strongly dilated and compressed hind tibie ; but they are shorter, and the dilatation is

gradual and progressive from base to apex; in V/. @sopus it is greatest in the middle,

and the outer edge of the tibia forms a flexuous line.

The species is closely allied to the common Mecometopus olivaceus, Lap. & Gory, of

South Brazil. In colour and markings they are nearly alike; and the Brazilian species

even shows traces of the basal ridges of the elytra.

Distinct from WU. esopus (which it greatly resembles in colours, although the markings

towards the base of the elytra are different) by the much shorter forehead, longer

antenne, the absence of elytral ridges, and the undilated tibie. It also greatly re-

sembles WV. olivaceus (L. & G.), which has a similar short forehead; but the markings

on the basal half of the elytra are very different from those of this species. I. centurio,

a similarly coloured but very distinct species, from South Brazil, agrees also with it in

the shorter forehead. The plane surface of the forehead and the comparatively slender

hind femora decide me to place these three species in Mecometopus rather than in

Neoclytus, to which genus they might be referred if attention were not paid to this

character. The two genera, however, graduate into each other, as is the case with all

the generic groups into which modern coleopterists have attempted to divide the Clytint.

As stated in my enumeration of the Longicorns of Chontales (Joc. cit.), the single

specimen taken by Belt differs from Chevrolat’s description and figure by an addi-

tional short yellow longitudinal stripe at the base of the elytra. A similar stripe lies

also nearly parallel on the epipleura near the shoulder; and the antenne appear shorter

and thicker. It is impossible from a single specimen to decide whether these differences

indicate a distinct species. The length and flatness of the forehead and the slenderness

of the hind legs bring the species within the definition of the genus Mecometopus.

Clytus (div. Xylotrechus), Chevr. Ann. Soc. Ent. Fr. 1860, p. 456.

Xylotrechus, Lacord. Gen. Col. ix. p. 77.

A widely distributed genus, distinguished by the raised lines of the forehead. It; 1s

represented in high latitudes in Europe and in North America, and is abundant both in

species and individuals in Tropical Asia; but it is not known to occur in South

America, and one representant only is known from Mexico and Central America.

About fifty species have been described.

TILLOMORPHA.

Tillomorpha, Blanchard, in Gay, Hist. d. Chile, Zool. v. p. 482 (1851) ; Lacord. Gen. Col. ix. p. 90;

Leconte, Smiths. Misc. Coll. no. 265, pt. 11. p. 320. .

The latest definitions of this genus given by authors leave its limits in a very un-

‘satisfactory state. According to Lacordaire and Leconte, simple, rounded eyes are an

essential feature; but the type of the genus, 7. lineoligera, of Chili, has the usual

reniform eyes of the Cerambycide. In the Munich Catalogue an Australian species is

enumerated in the genus, which is unlikely to be its true place. If the views of the

authors above named are correct, the genus ranges from Chili to the middle States of

North America, including Brazil, Colombia, and Mexico.

Only four species properly belonging to this genus have been described, all North-

American. The following is strictly congeneric with Leconte’s type E. picipes:—

1. Huderces reticeps.

Parvus, nigro-piceus; antennis, pedibus elytrisque rufo-castaneis, nitidis, his fascia recta mediana eburnea ;

capite reticulato-punctato; pronoto longitudinaliter strigoso; thorace postice valde, antice minus con-

. stricto, medio paullo dilatato et convexo.

Long. 27 lin.

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

Distinguished, besides its minute dimensions, by the net-like sculpture of the surface

of the head and by the form of the thorax, which is somewhat constricted near its anterior

margin and very greatly narrowed, as well as depressed, at the base, the middle portion

being dilated (more so in some examples than others) and convex. The antenne are

very similar in form and proportions of the joints to those of E. picipes. THe elytra

have only a slight and obtuse elevation at the base on each side, behind which they

are depressed, becoming moderately convex again posteriorly, with rounded apices ;

their surface is shining and sparsely punctured, each puncture bearing a long erect

bristle. The femora are abruptly clavate, and the hind tarsi short, as in E. picipes.

One species only is yet known of this genus, remarkable for the clavate, almost

globose, third and fourth antennal joints in the male. |

When I drew up the diagnosis cited above I had not seen the female of the genus,

but mistook the individuals with shorter antenne for that sex, these organs differing

considerably in length in the different specimens. Among the series of the insect in

Belt’s collection, acquired by Mr. Godman since the death of that traveller, there

is a single true female, distinguished at once by the simple antenne, thus showing

that the tumid joints are only a sexual character. There is also a sexual difference in

the terminal joints of the antenne, which are much dilated in the female.

ANCYLOCERA.

Ancylocera, Serville, Ann. Soc. Ent. Fr. 1834, p. 107.

Peculiar to America, ranging from the Argentine Republic in the south to the

middle States in the north. Eight species have been described.

1. Ancylocera macrotela.

Ancylocera rugicollis, Bates, Trans. Ent. Soc. 1872, p. 191 (nec Fab.).

A. bicolor Ol. (=rugicollis, Fab.) simillima, sed differt antennarum articulo undecimo elongato, apice solum

hamato, necnon elytrorum apice extus angulato. Nigra, elytris abdomineque rubris; thorace punctato

et transversim rugato ; elytris crebre dorso seriatim punctatis.

Long. 5-6 lin. § 9.

Hab. Guatema.a, 8S. Gerénimo (Champion); Nicaragua, Chontales (Belt).

Very closely resembling the North-American A. rugicollis, Fab. (=bicolor, Oliv.),

differing from that species chiefly by the greater length of the eleventh joint of the

antenne in the male (the terminal joints were wanting in the example I formerly -

determined as A. rugicollis). In A. rugicollis, as in A. cardinalis, the eleventh joint

in the male is excessively short, and forms a slightly curved hook; but in A. macrotela

it is more than half the length of the tenth joint, and the hook is formed by the

ANCYLOCERA.—STENYGRA. 69

minute appendage or false joint at the end. In support of this specific difference it is

to be noted that the outer edge of the apical truncature of the elytra forms a more

distinct angle, and the femora are less abruptly clavate. The elytra, too, are relatively

shorter, and their punctures larger and more separate.

2. Ancylocera sallei.

Ancylocera Sallei, Buquet, Arch. Entom. i. p. 832".

Hab. Mexico (Sallé +).

Distinguished (infer alia) by the brown sutural streak of the elytra.

CHAMPIONA, nov. gen.

Corpus fere cylindricum, angustum. Caput parvum, antice verticale, inter antennas modice elevatum lineaque

grosso, mox a basi dilatato, articulo 8° quam cexteri multo longiore, 4° quam sequente breviore, 11°

quam precedens longiore, curvato.

A new genus is necessary for the reception of an extraordinary and beautiful little

Longicorn, of which Mr. Champion has recently sent home a specimen. Although

wanting most of the obvious characters of Ancylocera, I think there can be no doubt

its affinities lie close in the direction of that genus. The vertical forehead (though

decidedly longer in Championa), general form of the head, the elongate, unarmed

thorax, the large but not inelegant sculpture of the upper surface of the body, and the

general shape of the legs, all remind one of Ancylocera; but a stronger indication of

affinity still is afforded by the curved tips of the antenne.

1. Championa aurata.

Gracilis, cylindrica, late viridi-aurata nitida, sparsim breviter cinereo-setosa, elytris fasciola angusta cinerea

paullo ante apicem; capite rugoso-punctato; thorace omnino transversim phicato ; elytris crebre, grosse,

versus apicem subconfluenter punctatis, apice utringue bispinosis.

Tong. 54 lin. (?).

Hab. Guarmmana, Calderas (Champion).

The whole insect is of a bright brassy-green colour, glowing on the head and thorax

with a golden or red-golden hue. The ashy pubescence is very long and somewhat

dense on the legs, antenne, and under surface of the body, but it-does not obscure

the bright ground-colour.

STENYGRA.

Stenygra, Serville, Ann. Soc. Ent. Fr. 1834, p. 95.

Five species of this conspicuous Tropical-American genus have so far been described.

Allied to Stenygra, and equally remarkable in form and coloration. Its range is

similarly restricted to Tropical America, the species described by M. Thomson as

Celomarthron chilense being with great probability a Central-American and not a

Chilian insect. Four species are known.

Hab. Guatemata, Zapote (Champion).

Differs from P. bilineatum and the rest of its congeners by the single eburneous

line of the elytra, which is nearly straight, curving only very slightly outwards, and

extending from the base to within a short distance of the apex. The apical margin is

obtusely rounded. The thorax is similar in form to that of P. bilineatum, but very

different in sculpture, the flanks being opaque with excessively minute sculpture, and

the dorsal surface for a considerable breadth polished and scored transversely, but not

densely, with fine ruge.

Agrees with C. lepriewri in the spinose apices of the four hinder tibiz and the equally

spined exterior angle of the elytral truncature. C. spinipennis, Bates, from the

Amazons, agrees in these points of structure, but differs a little in colours and markings.

EVANDER.

‘This species closely resembles EZ. nietot in colours, one variety having the black

‘circumscutellar spot which seems at first sight to be distinctive of H. nietoi. The

scutellum, however, seems to be constantly different in form, being narrow with straight

sides in E. nobilis, and broad with incurved sides and narrowed to a point in E£. nietot.

partly imbedded. The black vitta is, in fact, only the surface-colouring of-a narrow

strip of the integument, which is vertically flexuous, and at its extremity (near the

centre of the pronotum) is detached from the sides of the sulcus. The same peculiar

structure is seen in E. nobilis; but the sculpture is not so coarse in that species. The

scutellum is formed nearly as in EL. nietot.

DELTOSOMA. |

Deltosoma, Thomson, Syst. Céramb. p. 258 (1864); Lacordaire, Gen. Col. ix. p. 163.

This genus belongs to a small group in which the elytra are dilated and flattened out

in imitation of the Lycide (tribe Malacodermata), the characteristic colours of which —

they also imitate. Deltosoma is further remarkable for the distinct lateral margins

of the pronotum, a character of the Prionide family. Only one species has been

described; but others, all very closely allied, exist unnamed in collections. The range

of the genus is confined to-Tropical America, from Bolivia to Guatemala. |

Long. 53-83 lin. ¢ Q.

Hab. GuaTEMALA, San Gerdnimo (Champion).

The amount of tawny-yellow colour on the thorax is variable: there is always a spot

on the front margin near the middle; but sometimes there are also two other spots

nearer the disk; the underside of the thorax is sometimes nearly entirely fulvous.

PTEROPLATUS.

Piteroplatus, Buquet, Rev. Zool. 1840, p. 287; Ann. Soc. Ent. Fr. 1840, p. 385; Lacordaire,

Gen. Col. ix. p. 164.

The species of this genus (also peculiar to America) closely mimic the Lycide, and

they are more numerous than the Deltosome. The range is rather more extended,

reaching from the Argentine territory in the south to Florida in the north. Twenty

species have been described.

PTEROPLATUS. 73

1. Pteroplatus quadriscopulatus.

Pi. variabili (Sallé) simillimus, at differt utroque sexu articulis antennarum 3°-6" dense penicillatis. Elongatus,

Hab. Guatemata, Zapote, Capetillo (Champion).

Closely resembling Pt. variabilis, Sallé (Caraccas, Venezuela); variable in colours

like that species, though not quite in the same manner, and in shape offering no per-

ceptible difference. It differs, however, constantly in both sexes in having the antennal

joints from the third to the sixth furnished on one side with a long and very dense

brush of silky hairs, Pt. variabilis having such a brush only on. the sixth joint.

2. Pteroplatus sellatus.

Differs from Pt. quadriscopulatus in the form of the thorax, which is trapezoidal,

with nearly straight sides, instead of bulging in the middle. The colours are nearly

the same.

3. Pteroplatus octocostatus.

Subtriangularis, elytris mox ab humeris gradatim ampliatis, apice minus obtuse rotundatis. Niger, brevissime

The form of body is similar to that of Pt. lycoides; but the elytra are more broadly

dilated, and the thorax is relatively smaller, besides wanting the constriction at the

base which is seen in that and other species of the genus. The large number of

narrow and sharp elevated lines of the elytra are also a distinguishing character of

Pt. octocostatus.

none of which extends further beyond the zone included in the scope of this work than

Texas on the one hand and Colombia on the other. The Texan species (C. rimosus)

Hab. Guatemata (Deby 1), Zapote (Champion).

Two specimens of this superb insect have been sent home by Champion, both

females. I believe I am right in referring them to C. iridescens, White, of which the

male only has been described. The colour of the elytra, however, is more intensely

metallic, showing no trace of pale ferruginous ground-colour. The sculpture of the

thorax is similar in the two sexes, thus differing greatly from the closely allied species

C. rimosus of Texas, in which the male only has a thickly sculptured thorax (no smooth

dorsal space being left), the female having the same part smooth, with only a few

scattered punctures. On the authority of M. Sallé, C. tricolor (Waterh.) has been

recorded as the female of C. iridescens; but C. tricolor differs greatly in the sculpture

of the thorax, and belongs to quite a different section of the genus. The grooves of the

third to fifth antennal joints described by White (in which the female specimens agree

with the male) are a strong indication of affinity with C. rimosus, which has in both

CRIOPROSOPUS. 75

sexes similarly grooved joints. There is no difference of colour between the sexes of

C. rimosus.

5. Crioprosopus basileus.

Oblongus, valde elongatus, rufo-castaneus, infra ,griseo-sericeus, elytris splendide viridi-eneis subtilissime

sparsim punctatis, hic illic transverse rugatis; thorace valde transverso, lateribus post medium tubere

magno subconico, dorso creberrime punctato, linea lata dorsali levi, antice dilatata et post dilatationem

iterum angustata, juxta basin dilatata; mesosterno declivi.

Tong. 17 lin. Q.

Hab. Mexico, Oaxaca (Fenochio).

_ Very closely allied to C. iridescens?. It differs very little in colour, the red under

surface and femora only being of a duller, castaneous hue, scarcely differing from the

slightly darker tibize and sides of the mesosternum, and the elytra being greener and less

golden, as well as very much less punctured and wrinkled. In form there are well-

marked and important differences in the thorax and mesosternum. The sides of the

former instead of being obtusely rounded are produced into a large and nearly conical

tubercle ; and the smooth dorsal line is narrowed instead of widened (as well described by

White) behind the anterior dilatation. The mesosternum (between the legs) gradually

slopes forward, and is not produced into a large tubercle with vertical anterior face as

in C. iridescens.

6. Crioprosopus tricolor.

Callona tricolor, Waterhouse, Trans. Ent. Soc. 11. p. 228 (1840)}.

Hab. Panama, Obispo (Salvin).— VENEZUELA ?

The specimen taken by Mr. Salvin differs from that described by Waterhouse only

by the amount of red colour on the sides and under surface of the thorax, the separate

spots, as described, being united into a large lateral spot reaching nearly to the front

margin and prolonged in a ring underneath the prothorax. The mesosternum is pro-

duced: into a conical projecting tubercle.

ring of red on the femora and the presence of a red spot on the sides of the thorax

under the tubercle. But the antenne are twice the length of the body, the terminal

joints especially being slender and greatly elongated, the eleventh as long as the ninth

and tenth taken together. The thorax differs also in being covered on the sides and

under surface with a dense and coarse punctuation. This sexual difference and the

very prominent mesosternum appear to be distinctive characters of the group of

Crioprosopt having polished metallic elytra; and the name Callona given by Waterhouse

might be conveniently applied to it. The closely allied C. viridipennis, Latreille, from

Colombia, was included in Crioprosopus by Dupont.

METALEPTUS.

Metaleptus, Bates, Trans. Ent. Soc. 1872, p. 192.

Five species of this genus have been described, all from Mexico and Central

America except one, which I have not seen, and which is stated to be from Brazil.

Hab. Mexico!; Nicaracua, Chontales (Belt, Janson)?.

Although not perfectly agreeing with Chevrolat’s description, especially with regard

to the “trois nervures longitudinales non entiéres” of the elytra, I have no doubt my

M. marginellus is the same species as his P. angulatus. There is no difference worthy

of note between Chontales and Mexican specimens which I have compared ; and the

surface of the elytra, although apparently very smooth and velvety, shows in certain

lights traces of faint longitudinal raised lines, which may be the “nervures ” described

by the French author. |

2. Metaleptus binoculus. (Tab. VI. fig. 7.)

Since describing this species from a single Mexican specimen, I have seen three

others from Chontales, and all are females. As, on the other hand, all the MZ. angulatus

(marginellus) I have had an opportunity of examining, five in number, are males, it is

very possible they are the sexes of one and the same species. J. binoculus, besides

the different disposition of colours, differs constantly from M. angulatus in the sides of

the thorax being armed | with a 2 very distinct conical tubercle instead of being simply

angulated. :

3. Metaleptus coccinatus.

Metaleptus coccinatus, Bates, Trans. Ent. Soc. 1872, p. 193.

The lateral tubercles of the thorax are long and pointed; and the elytra are

separately rounded at the apex; the scutellum is.red. The single example is a female,

and possibly an extreme variety of M. angulatus.

4, Metaleptus pyrrhulus.

Minor, gracilis, niger, griseo-se®catus, thorace rufo-coccineo, maculis 4 dorsalibus nigris, elytris utrinque

macula magna triangulari humerali rufo-coccinea, humeris ipsis nigris; capite rufo, fasciis verticis et

Hab. Guatemata, San Gerdénimo (Champion).

This beautiful little species offers many peculiarities, but is undoubtedly congeneric

with Metaleptus. The form and proportions of the antennal joints, shape of the sterna,

head, and palpi, and the proportions of the legs and tarsi offer no difference worthy

of note. The chief divergent features reside in the thorax and elytra,—the former

being relatively narrower and longer, with very uneven convex surface and a central

short ridge; the latter having vertical epipleure. The red colour of the head,

thorax, and base of the elytra is very bright and silky under the lens, but opaque, owing

to the closeness of the alveolated sculpture. The four black spots of the thorax (two

obliquely placed on each side of the disk) are clothed with long black hairs, the

central ridge remaining red. The scutellum is moderately elongated, little more so

than in WU. angulatus. The basal red part of the elytra is bounded very obliquely

behind, the line commencing on the suture, not far from the scutellum, and terminating

on the sides at nearly two thirds the length of the elytra, a narrow sutural border at

the base and a humeral spot remaining black. ‘The legs are very long, the hind

thighs projecting much beyond the apex of the body, linear and briefly bidentate at the

tip; the hind tibie are flexuous and rufous towards the tip; the hind tarsi are of the

same elongated proportions, the lobes of the third joint narrow, and the soles densely

hairy.

Much resembling the figure given by Lacordaire of his 0. ornaticollis, but differing

in the much less prominent thoracic tubercles, the broader scutellum, and the black

marks of the thorax, these latter consisting (instead of three vitte) of five spots, two in

a line on each side and one near the base in the middle. The under surface is densely

clothed with long silky pubescence of a golden-tawny hue, the episterna of the meso-

thorax being black. The elytra are very closely punctured, coarsely at the base,

more minutely towards the apex; and there are two faint elevated lines down the

middle of each. |

Of similar form to Tylosis, but without the supplementary (12th) antennal joint

which distinguishes that genus. The species, as a rule, are remarkable for their dense

and somewhat long pubescence. Like Tylosis and many nearly allied genera it is

restricted to the southern and western regions of North America, including the

northern parts of Mexico. Eight species have been described from the United States.

1. Crossidius palmeri.

black spot commencing a short distance behind the scutellum (to which it is some-

times joined by a narrow black sutural edging) forms a long broad sutural vitta with

straight sides until near the apex, where it is suddenly dilated to the lateral margin.

The black basal fascia is variable in width. The punctuation of the elytra is coarse,

and becomes scarcely finer towards the apex; but the punctures are more separated

near the base, and dense or even confluent near the apex. ‘The prothorax is black

beneath in all the specimens.

Differs from the rest of its congeners in the elevated lines of the elytra, which,

although only rudimentary, indicate a relationship with Mannophorus, Ischnocnemis,

and other genera distinguished by raised ivory-like stripes on these organs; the

resemblance is increased by the rudimentary lines being in the centre of the two

- yellowish vittee which alternate with the blue-black stripes of the elytra. The thorax

is acutely margined at the base, the lateral (posterior) angles showing an acute pro-

jection similar to that which is exhibited in an exaggerated degree in Entomosterna

and allied genera. The long tawny hairs with which the body and legs are densely

clothed, the declivous mesosternum, short hind tarsi, and equilateral triangular

scutellum induce me to place the species in Crossidius.

MANNOPHORUWS.

Mannophorus, Leconte, Proc. Acad. Phil. 1853, p. 442.

A genus restricted, as far as at present known, to Northern Mexico and Texas. It

_ is very closely allied to other small generic groups from the same region.

The antenne of the female are much shorter than in the corresponding sex of

M. letus; and the scutellum, though broad, is more acutely pointed behind ; other-

wise the generic characters are very similar in the two species. The raised line of the

elytra is narrow and well defined; but the absence of a pale stripe accompanying it

gives a different facies to the insect from that of VW. letus and other allied species.

ISCHNOCNEMIS.

Ischnocnemis, Thomson, Systéme Céramb. p. 199 (1864).

The single Mexican species on which this genus was founded is closely allied to

Mannophorus, the chief difference lying in the greater length of the basal joint of the

hind tarsi and the attenuated pointed apex of the scutellum. The species is much larger,

however, and relatively longer, with longer antenne. Leconte places /schnocnemis

in his group Tyloses, on account of the alleged truncated apex of its mandibles. I find

both mandibles acutely pointed ; and as he further states that the genus has a pro-

tuberant in contradistinction to a sloping mesosternum, which is not the case, it is to

be inferred that he has wrongly identified it.

SPHENOTHECUS.

Sphenothecus, Dupont, Mag. Zool. 1888, CL. ix. p. 55.

Lacordaire suggested that S. cyanicollis, Dup., should be detached from this genus

and formed into anew one; and Leconte proposed to refer it to Entomosterna: the

latter author proposed further to divide the remainder of the genus into two; but,

after a careful examination of many of the allied forms, I think it preferable to retain

Sphenothecus as Dupont first defined it. The genus relies, then, for its unity more upon

the vertical front of the mesosternum, the elongated scutellum, and short posterior

tarsi than on the raised lines of the elytra and the form of the thorax. Eight species

are now known, all from Mexico and the adjoining countries, north and south.

One species only, from Brazil, was referred by Chevrolat to Gambria as a section of

Cyphosterna. Lacordaire, on the other hand, proposed to limit Cyphosterna to those

species in which the second ventral segment of the male was abnormally lengthened.

As he knew only one of Chevrolat’s species which possessed this character, he referred ©

the rest doubtfully to Gaméria, a view which we provisionally follow. The species are

very rare in collections; two were described by Chevrolat from Mexico and three from

Brazil and Bolivia. To these I am able to add one from Sonora.

The species taken by Mr. Belt, in the female sex only, is certainly distinct from

D. mandibularis. It is narrower and more convex, as Dupont describes it; and the

third joint of the antenne is shorter. In colour it resembles the pale variety figured

by Dupont, but shows no darker markings at the base of the elytra.

TRACHYDERES.

Trachyderes, Dalman in Schénherr, Syn. Insect. 1. iii. p. 864; Lacordaire, Gen. Col. ix. p. 201.

About fifty species of this highly characteristic American genus have been described.

Its range extends from the basin of the La Plata to Mexico; but it has not yet been

recorded from the United States or from Chili. Judging from the diversity of the

specific forms, South Brazil appears to be the centre of distribution of the genus,

the species being few and little varied in Central America and Mexico.

This species or local form is more nearly allied to 7. elegans than to any other of

the species or subspecies belonging to the succinctus group of this difficult genus.

But almost the sole structural character which distinguishes both from the South-

American type species is the narrower scutellum, which is only noticeable when the

specimens are very attentively compared. ‘The long brown erect hairs with which the

under surface of the body, especially the breast, is clothed is certainly a good character,

but is only visible in well-preserved specimens. The general form of the body is

somewhat different in average individuals, especially of the male; but there are some

in which this difference is not at all perceptible. I have never seen, however, in the

best-developed males of 7. subpilosus and elegans the robust form which corresponding

individuals of J. succinctus assume, with their voluminous thorax, thick and rough

basal joints of the antenne, and tapering elytra. The colour of the hind tibize is

subject to rare exceptions: in the majority the apex is dark brown, whilst in the true

Guiana succinctus the tibia are unicolorous tawny yellow like the abdomen. With

regard to the distinction of 7. subpilosus from T. elegans, it is almost exclusively

one of colouring; and some specimens approach the tawny hue, with black borders to

the white fascia of the elytra, which distinguishes 7. elegans.

This is probably a variety only, in which the white fascia is reduced in size and

broken into two transverse spots on each elytron. The variation in the elytral belt

apparently occurs in both 7. succinctus and subpilosus, the Nicaraguan specimen having

the narrow scutellum of 7. pilosus; whilst a South-American specimen I have seen has

a scutellum rather broader at the base and resembling 7’. succinctus.

Fam. LAMIIDA,

The family Lamiide is not susceptible of division into subfamilies having any

approximation towards equality of rank with those I have proposed for the Prionide

and the Cerambycide. As the genera and species, however, are exceedingly numerous

and range themselves for the most part around certain tolerably definite type forms,

of lower rank than the subfamilies just alluded to, I here adopt a system of “groups ”

as a convenient arrangement for bringing together these evidently natural assemblages.

The groups will be an amplification of the “subtribes” which I proposed and defined

in treating of the Lamiade of the Amazons valley (Ann. & Mag. Nat. Hist. ser. 3, viii.

July 1861), and not equivalent to the “groupes” of Lacordaire’s ‘Genera des Coléo-

ptéres,’ although, for facility of reference, I follow the order of succession established

in the ‘ Genera.’

Group DORCADIONINI.

There seems to me no valid distinction between the two “groupes” Dorcadidides and

Parménides of Lacordaire. Of the two characters mentioned by him, the first (the

form of the intercoxal projection of the basal ventral segment) is inconstant; and the

second (the oblique outer groove of the middle tibia) rests on mistaken observation, at

n 2

92 LONGICORNIA.

any rate in the species of Phrynidius (Dorcadidides), to which the existence of a groove

is denied by him: the groove exists, although low down on the shanks. The funda-

mental character of the existence of an epistome, or rather the exposure of the basal

piece of the labrum, by which Lacordaire distinguishes three separate “ groupes” of

Dorcadionini, does not possess that absolute importance which he attributed to it,

several species of true Dorcadion (D. humerale, Gebl., and allies, also a new species

from Peking) showing the basal piece as distinctly as do the Parménides. All these

“groupes” of Lacordaire may therefore be fused into one. But from this his Hexatri-

chides, I think, ought to be separated, as belonging to quite a different type. The

Dorcadionini require further to be purified by the withdrawal of certain genera wrongly,

as I think, admitted by Lacordaire and other authors into the group, e.g. Parmenonta

and Mesolita.

PHRYNIDIUS.

Phrynidius, Lacordaire, Gen. Col. ix. p. 262.

This genus, peculiar to Mexico and Central America, is closely allied to Microtragus,

an Australian form agreeing in the shape of the head and in the insertion of the antenne.

Lacordaire, however, placed the two genera in different “groupes.” The intercoxal

process is of similar form in both. Three species are now known, two of which are

new.

1. Phrynidius singularis.

Elongato-ovatus, tomento subsquamoso fusco vestitus ; capite retracto; antennis basi valde approximatis, ab oculis

longe distantibus, corpore brevioribus, scapo elongato subcylindrico, articulis 3% et 4% elongatis ; thorace

elongato, fere cylindrico, lateribus post medium tuberosis, dorso gibboso, tota superficie grossissime rugosa ;

elytris elongato-ovatis, humeris nullis, grosse punctatis, utrinque tuberculis magnis circiter duodecim

subseriatis ; pedibus modice elongatis, femoribus versus apicem paullo incrassatis; tibiis intermediis juxta

apicem oblique sulcatis ; onychiis minus divaricatis.

Long. 54 lin.

Hab. Guaremaa, San Gerdénimo (Champion).

The pro- and mesosternal processes are both strongly arched. ‘The intercoxal pro-

cess is obtusely rounded at the apex. The metathoracic episterna are wholly concealed

_by the sides of the elytra, which tightly envelop the flanks of the trunk and have a

simple, narrow, and almost perfectly straight margin without thickened rim. The

middle acetabula are open externally ; but, notwithstanding, the epimera do not intrude

within the opening. The antenne are almost contiguous at their base, the antennife-

rous tubers being short and vertical at the summit of the long trapezoidal forehead.

The scape is long and nearly of equal thickness throughout ; the third joint is a little

longer than the scape, and the fourth about a third shorter than the third, the two

together being about one third the length of the whole antenna. ‘The eyes are very

narrow, nearly divided, and coarsely granulated. |

PHRYNIDIUS.—MONEILEMA. 93

2. Phrynidius echinus.

Minus elongatus, tomento compacto squamoso fusco vestitus, sparsim distincte punctatus; capite retracto; an-

tennis basi approximatis, ab oculis distantibus, scapo curvato, articulo tertio maxime elongato, quarto breviore,

ceteris brevissimis equalibus; thorace minus elongato, medio paullulum dilatato-rotundato, disco con-

vexo plurinodoso ; elytris ovalibus, humeris nullis, utrinque tuberculis circiter duodecim subseriatis ; tibiis

intermediis extus juxta apicem oblique sulcatis.

Long. 4 lin.

Hab. Guatemata, San Juan, Sabo, Vera Paz (Champion).

More oval than P. singularis; thorax much shorter and its surface more even,

marked with a few distinct punctures; the elytra also smoother between the conical

tubercles and more regularly punctured. The antenne are different in the proportions

of their joints, the scape being much shorter, while the third and fourth joints are much

longer, being together as long as all the rest of the antenne, the fourth less than half

the length of the third, which latter is half as long as the scape. At the base they are

not so closely approximated, and for that reason less distant from the eyes.

Nearly of the same size as P. echinus, but much narrower and differing by the thorax

Collapteryx, Newman, Entom. Mag. v. p. 397 (1838).

Monilema, Leconte, Journ. Ac. Phil. ser. 2, ii. p. 167 (1852).

This genus is the North-American representative of the Palearctic Dorcadion, and

is nearly confined to the western and southern regions of the continent, one species only

being found so far east as the State of Missouri. ‘The species are numerous in Mexico ;

but it is exceedingly probable that many of those described are only varieties, some

of them being variable in punctuation and in the amount of pale tomentum with which,

especially on the upper surface, they are variegated. If we may judge by the form of

the thoracic tubercles and the humeral angles of the elytra, and disregard sculpture and

tomentose markings, the following eight would constitute only one variable species—

C. carinatum, Leconte, levidorsale, albopictum, infamie, perforatum, mortuale, and

sinistrum.

The insect described by Newman is of large size (one inch), and distinguished by

the scattered punctuation of the head and thorax as well as the whole surface (except

the apex) of the elytra. The form of the thoracic tubercles and humeral angles of the

elytra is not mentioned. An example in M. Sallé’s collection, named as a variety of

M. variolare, agrees very well with this description, as far as it goes. It is from

Mexico.

Group MONOHAMMINI.

This group in a natural arrangement would comprise at least two of Lacordaire’s

“groupes,” viz. Monohammides and Batocérides, the degree of completeness of the

cicatrice of the antennal scape, on which the author of the ‘Genera’ relied for the

separation of the two, proving to be much more irregular than he believed it to be.

The group contains a large number of genera, consisting nearly all of large and

beautiful species ; but they are chiefly confined to the tropical and warmer regions of

the Old World, being especially abundant in the Indian and Malayan regions. Out of

fifty known genera, only six occur in Tropical America; and of these three are almost

restricted to Central America and the neighbouring countries north and south.

special localities varieties in which the disk is almost as much spotted as in P. nivet-

sparsus. The varieties retain the sutural and (narrow) marginal vitte; they are as

Although the amount of difference between this and the Mexican 7. luciani is not

great, its constancy, as displayed in the large number of specimens taken at Chontales,

makes it necessary to distinguish the form by a separate name. JBesides the tenuity of

the dorsal yellow line of the thorax and scutellum, and the brighter colour of the line

and other stripes and spots, the ground-colour of the body shows a constant difference

in shade, and the elytra are more distinctly produced at the sutural angle of the apex.

different, although similar in position: they are of the purest white; and the ante-

median spot forms a large irregular patch, more or less connected with smaller neigh-

Closely allied to H. albiplagiatus, White (=inermis, 'Thoms.), from which it differs

by its greater size and more elongate shape, by the apices of the elytra forming distinct

elytron there are five large white or yellowish-white spots, one at the base, one on the

side before the middle, and another on the side behind the middle, sometimes united to

the fourth spot on the disk a little nearer the base, and, lastly, a rather elongate spot

near the apex. Besides these larger spots, which are nearly of equal size, there are

many smaller ones scattered over the surface. The elytra are very scantily and faintly

punctured; and the granulations near the base are smaller than in other species. ‘The

central white vitta of the thorax is slender, and sometimes reduced to two linear spots ;

the lateral vitta is broader, and sometimes reaches, without interruption, the anterior

prolongation of the apices of the elytra. Its colour and markings are also different, the

white upper surface being clothed with ochreous-yellow tomentum, quite uniform,

except that there are traces of patches of slightly darker shade on the elytra,

| MONOHAMMUS.

Monohammus, Serville, Ann. Soc. Ent. Fr. 1835, p. 91 (Monochamus, err. typ.).

Deducting the numerous species belonging to the genus Dihammus, Thomson (which

Lacordaire included in Monohammus), and the species of Tropical Africa (which are

generically distinct by the narrowness of the cicatrice of the antennal scape), the genus

Monohammus is confined to such species of the heterogeneous assemblage compre-

hended in recent works as are closely allied to the European and North-American

members enumerated by Serville and Lacordaire. To these naturally belong also a

few from Eastern Asia and India. About twenty species of true Monohammus have

been described. The following is the first yet recorded from America south of the

United States :—

1. Monohammus rubigineus.

M. clamatori (Leconte) affinis. Ferrugineo-fuscus, subtus ferrugineo-lanuginosus; vertice vittis duabus

approximatis et thorace vittis abbreviatis quatuor fulvis, elytris maculis numerosis ex parte confluentibus

tomentosis fulvo-ferrugineis; thorace latius cylindrico, transversim ruguloso; elytris passim aspere

punctatis (juxta suturam vix rugulosis), apice ad suturam paullo productis ; antennis rufescenti-fuscis.

Long. 83-94 lin. § Q.

Hab. Mzxico (Sallé).

Two examples in M. Sallé’s collection. The species is very closely allied to the

Californian JL. clamator, having similar spots of close rust-coloured tomentum scattered

over the elytra. It is, however, a much broader insect, less wrinkled on the elytra,

and has the under surface of the body densely clothed with long woolly hairs.

Group APOMECYNINI.

The Old-World genus Apomecyna forms an easily-recognized and distinct type in the

Lamiade, uniting a cylindroidal form of body and unarmed thorax with subparallel

tarsal claws, sinuate external edge of the tibi, and especially a short antennal scape,

suddenly thickened on the outer side from the base, and entire at the apex. The more

104 LONGICORNIA.

typical genera are further recognizable by the general form of the antenne, which are

shorter than the body and have the terminal joints from the fifth much abbreviated,

closely fitted together, with the end joint pointed. In some of the genera, however,

the antenne are lengthened, being considerably longer than the body. The degree of

dehiscence of the middle haunch-sockets is variable; and the mesosternal epimera are

sometimes very short, not reaching the aperture of the sockets. This structure seems

to have misled Lacordaire, who gives, in some of the genera, the middle sockets (“ cavités

cotyloides ”) as closed, which they are not in reality. Owing partly to this and partly to

his habit of regarding geographical distribution as a group-character, he was led to

divide the Apomecynini unnecessarily into numerous minor groups. | |

PARMENONTA.

Parmenonta, Thomson, Physis, ii. p. 157; Lacordaire, Gen. ix. p. 273.

Lacordaire referred this genus to the Dorcadionini, owing to the superficial similarity

of its species to the Parmene. He had not, at that time, noticed the systematic value

of the degree of divergence of the tarsal claws; otherwise he could not have failed to

recognize the true affinities of the genus. Parmenonta, in fact, is connected by insen-

sible gradations with Adetus (=Agennopsis, Thoms., Lac.). It is sufficiently distinct,

however, by its shortened metasternum (and consequent approximation of the two

hinder pairs of legs) and the more or less dilated or suboval form of the elytra. Five

species are now known, from South Brazil, Central America, and Mexico; it has not

yet been recorded from the northern parts of Tropical South America.

Lacordaire describes the elytra as soldered together, which is not the case: they are

free; and the under wings are present. He says also that the intermediate tibie have

neither groove nor sinus on their outer edge: this also is not strictly exact; they have

a shallow sinus, fringed with the usual longish hairs, near the apex. The same tibie

in P. valida have also a tooth-like projection at their inner apices, a structure more

strongly pronounced in the male than in the female; it is not seen, however, in the

other species.

The group appears to have a real affinity with Parmena, but a much closer one with

the Xylotolini, an interesting group consisting chiefly of Antarctic forms, which has not

yet been systematically defined.

Hab. Guatemata, Zapote (Champion).

Shorter; the elytra, especially, relatively shorter and more ovate than in P. valida.

The head and thorax coarsely punctured; the elytra punctured with less regularity

than in P. valida, the punctures being larger and smaller, as in that species, but

without much tendency to range in lines. At the base the elytra are scarce perceptibly

wider than the base of the elytra; but the shoulders are rather distinct, and the sides

are gradually rounded outwards to two thirds the length, and then more rapidly

rounded to the sutural apex, near which the margin is slightly sinuated; the pale

spot lies transversely across the disk at two thirds the length; and there is another, less

distinct, similar pale spot near each shoulder. ‘The tibie are shorter, and more

triangular in shape than in P. valida. The mesosternum is plane and not at all pro-

minent ; the middle cotyloid cavities are distinctly open; and the mesothoracic epimera

reach to the opening.

form of the elytra, which in P. aldisetosa are dilated (very slightly) immediately from

the base, and commence again to taper immediately after the middle, whilst in the

other two species they are nearly parallel at first for a short distance and do not

diminish again in width till shortly before the apex. The consequence of this diffe-

rence in the curvature of the sides is that the greatest width of the elytra falls a little

nearer the middle in P. albisetosa than it does in the allied species. Together with

this difference of form, there is a distinguishing character in the clothing of the surface,

furnished by the small pencils of short white bristles, which are conspicuous in P. albi-

setosa but are not noticeable in the other two species.

Distinguished from Parmenonta, to which it is very closely allied, by the metasternum

being of normal length. The species have no longer any resemblance in form to Par-

mena and the Dorcadionini. Including Zautoclines (admitted, with some reservation, by

Lacordaire, but which possesses no points of difference applicable to the extensive

series of species now known), the genus is a large one, including more than a score

of species, all peculiar to America and ranging from Chili in the south to Mexico in

the north. A. analis, recorded from Pennsylvania, is said by Leconte to be a South-

American insect. The species of Central America are numerous, and varied in form

and markings. |

ADETUS. 107

The mesosternum is plane, as in Tautoclines; but the anterior part of the prosternum

is fitted for the reception of the head (which thus rests on the anterior haunches) much

more completely than in Adetus validus. The two chief: characters adduced for the

genus Tautoclines are thus proved not to go together. The elytra in A. griseicauda

are rotundate-dilated before the apex; and the apex itself has no trace of emargination

or truncature.

Hab. Nicaragua, Chontales (Belt).

The degree of prominence of the mesosternum having proved an unimportant character,

this species must be considered an Adetus, with which it agrees in general form and

facies, as also in the shape of its prosternum, the anterior part of which is hollowed

out to receive the head in repose; the lateral angles of the cavity thus formed are

dentiform, as in the typical species.

I can see no difference between Chontales and Mexican specimens except in the

punctuation of the elytra, the punctures being more distinctly impressed in lines in the

Mexican than in the Nicaraguan form. The shape of the elytra is similar in both—

namely, elongate with the sides strictly parallel in the middle. The antenne are of

precisely the same form as in Adetus muticus; and the prosternum is shaped out in

front to receive the head in repose, but is more oblique and plane than in the typical

species.

108 LONGICORNIA.

The numerous examples sent home by Champion differ constantly from equally

numerous examples of A. binotatus, taken by Belt, in the relatively shorter and more

ovate elytra. There is also a minor and less reliable difference in the mode of emargi-

nation of the apex of the elytra, the outer angle of which in A. binotatus is always |

more produced than the sutural, whilst in A. subellipticus the two angles are equal.

The antennal joints, from the fifth, are whitish at the base, and there is a narrow

whitish vitta on’ the lower flanks of the prothorax, in both species. The form of the

pro- and mesosterna offers little difference. |

8. Adetus antennatus.

It is difficult by description to make clear the differences between this species and

A. binotatus, the colour and markings being very similar. ‘The two, however, are very

distinct. A. leucostigma is a decidedly narrower insect, and is covered with coarser

pubescence; the elytra are more gradually attenuated posteriorly, and the seriated

punctures are more oblong.

10. Adetus denticauda.

A. binotato similis, sed differt elytris apice utrinque valde bidentatis etc. Elongatus, subcylindricus, subseneo-

fuscus nitidus, vitta laterali thoracis utrinque versus medium elytrorum continuata, macula transversa post

extend (slightly curving) as a compact stripe to about one third the length of the elytra—

the elytral part of the vitta in A. binotatus and allies being a broken, macular line.

Another important difference lies in the apex of the elytra, which, instead of having a

short oblique truncature near the suture, is transversely sinuate-truncate, with each

angle produced into a longish tooth or spine, the sutural one shorter and finer than the

external. The thoracic vitte are continued to the head, forming a short streak or spot

behind each eye, which, however, is not very distinct and is sometimes absent. ‘The

mesosternum is not at all prominent, but simply arched or nearly plane.

11. Adetus pictus.

Certainly distinct from A. denticauda, by its shorter and broader form and. the broad

stripe of compacter and whiter tomentum which extends from the hind margin of the

eye down the side of the thorax and the elytron nearly to the centre of the last-named.

A further difference is the stripe of similar tomentum beneath on the sides of head,

prothorax, and breast. An important structural difference is seen in the prominent

mesosternum, of which the front face is vertical.

12. Adetus excultus.

Hab. Nicaracva, Chontales (Beit).

Relatively as broad as A. pictus, but much longer; and the tomentose stripes and spots

are tawny-ochreous instead of white, although of the same dimensions and in the same

positions. Both species differ from A. denticauda in the postmedian spot of the elytra

being large and ovate (lengthwise) instead of narrow and transverse, and also in the pro-

minent and anteriorly vertical mesosternum.

PTERICHTHYA.

and consisting chiefly in the great elongation of the outer apical angles of the elytra and

the consequent gradual slope of the elytral surface near the apex. The mesosternum

is nearly plane, and the prosternum very gradually and slightly arched between the

anterior cox. I fail to see the character, mentioned by Lacordaire, of completely

divided eyes, the two lobes of these organs being connected by a narrow thread as in

the majority of the species of Adetus. The genus is peculiar to Mexico and Central

America.

The peculiar fish-like form and elongation of the apices of the elytra, which distin-

It is distinguished also by its extremely fine and scattered punctuation and shining brassy

ground-colour.

The exterior angle of the apex of the elytra is much less elongated than in P. pisct-

formis; but the sutural angle is armed with a sharp spine just as in that species.

P. furculicauda bears a close general resemblance to Adetus leucostigma, and, in short,

bridges over the difference between the two genera. The postmedian and subapical

stripes sometimes meet, as represented in our figure, in which it must be remarked the

artist has not successfully represented the general colour of the insect.

PTERICOPTUS.

Ptericoptus, Serville, Ann. Soc. Ent. Fr. 1835, p. 61.

This genus is one of the members of Lacordaire’s group Ptéricoptides, a highly arti-

ficial assemblage of genera which cannot conveniently be maintained. It is a rather

aberrant form of Apomecynini, but is better placed in this group than in the following,

from which it differs by its broad forehead, small, deeply-divided eyes, and short thick

antenne. It is peculiar to America; and the species, seven of which are now known,

have a great general resemblance to each other.

Apparently much resembling P. cruentatus, Thoms., from Cayenne, from the descrip-

tion of which it differs in the distribution of the markings. The gradually narrowed

elytra and the much produced exterior angles of the truncature, in the ¢, distinguish

it from all other known species.

There is in M. Sallé’s collection from Mexico a ¢ example which may probably be

referred to this. It is larger (8+ lines) and more uniformly pinkish brown on the elytra.

The most notable feature, however, is the simple oblique truncature of the elytra.

Group ATAXTINI.

Lacordaire’s “groupe” Ataxiides includes a small number of genera having “divergent”

(é. é. subparallel) tarsal claws, like the Apomecynini, but differing from them and other

groups in the much larger and more prominent eyes and narrower and shorter forehead.

The antenne are more or less elongate, with long and distinctly separated joints, and the

thorax is in general furnished with lateral tubercles. I propose to include in it the

“proupe” Ptéropliides of the ‘Genera, and the genera Epectasis, Amphicneia, and

Aletretia, which have been hitherto placed in widely different groups.

As far as at present known, the Ataxiini ate confined to the American continent, some

of the genera being peculiar to Brazil. |

Lacordaire omits the chief character which distinguishes this from the closely-allied

the antennal scape, a structural feature which did not escape Thomson. The genus

EPECTASIS. —,

Epectasis, Bates, Aun. & Mag. Nat. Hist. ser. 3, xvil. p. 294.

The true position of this curious genus is in the present group, notwithstanding its

extremely narrow linear form and the unarmed sides of the thorax. The antennal scape

has a similar narrow cicatrice to that of Parysatis. The middle cotyloid cavities,

however, are perfectly closed ; but this is a character which, as Dr. Leconte has shown,

does not possess the importance that Lacordaire attributed to it. The following is the

only known species :—

AEsylacris, Thomson, Physis, 11. p. 143 (1868) ?

Thad originally placed this genus in the group Onciderini, n near Dorcasta, on the ground

of its elongated and robust claw-joints. But the form of the antennal scape, shortness of

the muzzle, and the large convex eyes are characters foreign to that group, and betray

an affinity to the Ataxiini. The shape of the thorax and facies of the insect, however,

are very different from the Ataxiini; and I place the genus here only provisionally. The

notch on the outside edge of the middle tibie is not distinct as in Dorcasta. ‘The genus

is peculiar to Tropical America, some half a dozen species being known.

ASYNGENES.

Corpus parvum, cylindricum, nitidum, longe pilosum. Caput inter antennas depressum, antice brevissimum,

The position of this genus of minute Lamiade is extremely difficult to allot on the

system of Lacordaire. ‘The undecided form of the tarsal claws, which is midway between

his “ crochets divergents ” and “‘ crochets divariqués,” is the first perplexing feature ; and

the difficulty is not easily overcome by taking the signs of affinity presented by the other

structural characters. -By its general form and clothing the genus would seem to find

its natural place near Eupogonius, from which, however, the notched middle tibie and

shortened third antennal joint effectually remove it. In these points it most resembles

the genus Amphicneia ; and it is next to this that I propose to leave it. The antenne

are almost exactly similar; but the spined thorax and less parallel tarsal claws sufficiently

distinguish it. One species only is known, remarkable for its shining brassy colour.

Group DESMIPHORINI,

The insects composing this group are of elongate cylindrical form, with lateral

thoracic tubercles, widely divergent claws (at right angles to the axis of the tarsi), and

short forehead with well-developed eyes. Including in the group, Lacordaire’s Apoda-

syides, which agree in these characters, we have an assemblage of genera for the most

‘part remarkable for the long pubescence with which they are clothed, sometimes in the

form of eccentric tufts. In some genera the antenne only are densely hairy.

Eriopsilus, Bates, Ann. & Mag. Nat. Hist. ser. 3, xvil. p. 193 (1866).

I have referred to this genus a number of small, subcylindrical, pubescent species

allied to Desmiphora and Therchetes. The only one of Leconte’s species with which I

have been able to compare them is EL. suwbarmatus ; and with this they are certainly con-

generic, but they are generally more coarsely pubescent. All have short muzzles, large

coarsely-granulated eyes, and antenne in which the scape is short, thick, and abruptly

narrowed on one side at the base, with third and fourth joints elongated, and the fifth

to eleventh much shortened. The middle cotyloid cavities are not quite closed. In

most the middle tibize show scarcely any trace of the groove on their outer edge; in

others it is visible. There is a difference among the species, also, in the degree of

depression of the crown between the antenniferous tubercles: in some this depression is

scarcely perceptible; and such species, except for their long pubescence and cylindrical

forms, might almost be referred to Estola. Nine species have been already described,

from the United States, Central, and the northern parts cf South America. My genus

Eriopsiius is not to be distinguished from Eupogonius as here defined.

The antenne are more slender than in EZ. subarmatus and E. subceneus, but present

similar proportions as to length of the separate joints, the scape only being rather longer

in the other species ; its lateral tubercle is small, as in the rest of the genus, but more

sharply pointed.

Estola, Fairmaire et Germain, Ann. Soc. Ent. Fr. 1859, p. 524; Lacordaire, Gen. Col. ix. p. 643.

Seventeen species of this exclusively American genus have been described. The

range includes temperate regions from Chili in the South to the United States in the

North, Pogonocherus (?) sordidus (Leconte), from Lower California, being an Lstola

very closely allied to F. perforata.

PARESTOLA.

Genus. Estole affine, at differt pedibus longioribus femoribusque longius pedunculatis, necnon thorace spina

acuta laterali armato. Corpus oblongo-ovatum, subtiliter tomentosum. Caput angustum, inter antennas

depressum; tubera antennifera elevata. Antenne graciles, albimaculate, subtus ciliate, scapo paullo

elongato, intus mox a basi dilatato; articulo tertio maxime elongato, quarto paullo breviore, ceteris

modice abbreviatis equalibus. Oculi magni, grosse granulati. Thorax elytris multo angustior, late-

ribus acute spinosis. LElytra oblongo-ovata, modice convexa, crebre sublineatim punctata, apice rotun-

data. Pedes elongati, graciles ; femora clavata, apice longe pedunculata ; tibia intermedie extus leviter

sinuate. Prosternum inter pedes arcuatum, apice dilatatum. Mesosternum arcuatum; acetabula extus

perparum aperta.

The insect for which this genus is constituted differs from Hstola by its oblong-ovate

elytra, relatively much narrower head and thorax, and its longer legs with longer and

more slender peduncle to the clavate femora. It also differs by the lateral armature

of the thorax consisting of a short sharp spine instead of a conical tubercle. The

sculpture and clothing are very similar.

1. Parestola zapotensis.

Oblongo-ovata, atrofusca, nigro breviter setosa, elytris pallide fusco marmoratis; antennis articulis 4°, 6°, 8°

ATIMIOLA.

Corpus parvum, oblongo-ovatum, tomentosum. Caput inter antennas depressum, antice infra oculos breve,

paullo angustatum. Antenne corpore breviores, pallide annulate, scapo brevi, intus mox a basi dilatato,

articulo tertio fere dimidio breviore quam quartus. Thorax quadratus, elytris angustior, dorso quin-

quetuberoso, lateribus paullo post medium spina acuta armatis. Elytra oblongo-ovata, modice convexa,

apice rotundata, supra setosa, crebre punctata. Prosternum ante pedes liberum, inter pedes arcuatum,

apice dilatatum. Mesosternum nullo modo elevatum, concavum ; acetabula intermedia paullo aperta.

Pedes breves; tibiee intermedie extus distincte sinuate.

In the majority of its structural characters this genus closely resembles Hstola ; but

the oblong-ovate elytra, acutely spined thorax, and especially the shortness of the third

antennal joint as compared with the fourth, necessitate its separation. The thorax is

gradually narrowed anteriorly from the tips of the lateral spines, and sinuated behind

the spines—a structure quite foreign to Estola and Pogonocherus, and indicating an

affinity towards Exocentrus.

extus anguste angulata; intermedia extus ut in Pogonochero fere clausa. Pedes ut in Pogonochero, tibiis

intermediis prope apicem extus sinuatis et ciliatis.

A genus interesting from its close affinity with the North-Temperate Pogonocherus,

from which its more oblong form, hirsute clothing, and longer antenne at first sight

distinguish it. The only positive structural characters which it presents are the slender

form of the scape and the third and fourth joints of the antenne. The form of the

scape is decisive of generic distinctness.

1. Polisnus hirsutus.

Griseo-fuscus, undique griseo-hirsutus, antennis (scapo fusco.excepto) pedibusque pallide rufescentibus, thorace

Long. 3 lin.

Hab. Guatemata, Duefias, Capetillo, San Gerdénimo (Champion).

The body, antenne, and legs are clothed with long, grey, woolly hairs, which on the

dorsal surface of the elytra are replaced by more scanty, long, blackish bristles. The

elyrat are convex, with steeply declivous sides and apex and depressed disk; from each

shoulder proceed two sharp raised lines, neither of which reaches the apex, the space

between them being deeply punctured. Small pencils of stiff hairs surmount the slightly

elevated centro-basal crests, and form a line down the posterior part of the disk of each

elytron. The colour of the elytra may be described as tawny reddish, with greyish

black sides, the black colour spreading towards the middle posteriorly.

Group COMPSOSOMINI.

Including the Mrénéides of Lacordaire, the Compsosomini form a small and very

distinct group, containing seven genera and about thirty species, and peculiar to the

This species is distinguished from 7’. (Ischiocentra) maculosa (Bates), from the Amazons,

by the lateral prominence of the thorax not forming a distinct conical tubercle ; in colours

and markings there is a remarkable similarity between the two species.

The shape of the large vertical forehead in Tybalmia and allied genera is subject to

abrupt modifications from species to species. In the typical species (7. pupillata) it is

trapezoidal, the crown being narrowed and the frontal horns thereby brought more

close y together—a structure affecting the form of the thorax, which is narrowed ante-

riorly almost as in Jamesia. In T. ceca the forehead is rectangular; but in other

respects there is so close an affinity that it is impossible to separate the two species.

Such being the case, it is necessary to transfer to Zybalmia those species described as

Ischiocentre which have a similar form of forehead and of frontal horns, these features

evidently presenting more reliable characters than the form of the forehead. In Ischio-

centra clavata, the type of the genus, the frontal horns are vertical and the thorax sub-

cylindrical.

TRACHYSOMUS.

Trachysomus, Serville, Ann. Soc. Ent. Fr. 1835, p. 40.

Seven species of this distinct and remarkable genus have been recorded from Tropical

South America. It has not hitherto been known as represented in the part of the tro-

pical zone north of Colombia.

1. Trachysomus fragifer.

Lamia fragifera, Kirby, Trans. Linn. Soe. xi. p. 440.

Hab. Mexico, Juquila (Sai/é).—Sourn America, Cayenne to South Brazil.

A specimen in M. Sallé’s collection does not differ from examples from South Brazil.

The species is widely distributed; but in the Amazons region it occurs in a slightly

modified form.

ONCIDERES*.

Oncideres, Serville, Ann. Soc. Ent. Fr. 1835, p. 67 ; Lacordaire, Gen. Col. ix. p. 677.

Nearly fifty species of this fine genus of American Lamiade have been described, the

great, majority of which are confined to the tropical zone, a few only, of diminished size,

occurring in temperate latitudes, in the regions of the La Plata in the south, and in the

Atlantic States in the north. One species, 0. amputator, Fab. (=lherminieri, Forsstr.)

is found in the West Indies. | | | |

Lacordaire dwells, with good reason, on the heterogeneity of the contents of the genus

as at present defined. Some of the divergent points of structure seem to me only of

specific rank; but others are more important, and point to the existence of two natural

groups. In one group, of which O. callidryas may be taken as the type, the general

form is much less cylindrical and less convex, the thorax in both sexes as wide or wider

behind than in front, and the frontal horns of the male porrect. This group is very

closely allied to Zybalmia. In the second, or typical, group, the form is cylindrical

and convex, and the thorax (especially in the female) narrower behipd than in front:

The first section is almost of generic rank, and may be distinguished by the name of

Lochmeocles.

Section i. LOCHMAOCLES.

1. Oncideres callidryas. (Var. 2, Tab. IX. fig. 9.)

apicem versus obsoletis; antennis (scapo fusco excepto) rufo-castaneis.

Long. 73.lin.

Hab. Mexico, Toxpam (Sailé); Nicaragua, Chontales (Belt).

The irregular and widely-scattered punctures of the elytra effectively distinguish

this species from O. callidryas. ‘Towards the base some of the punctures are accom-

panied each bya small tubercle ; and near the apex they become smaller and shallower.

The spots of hoary tomentum are more or less tinted with fulvous, and are all of irre-

gular form, condensing most towards the middle of the sides.

8. Oncideres tessellata.

Oncideres tessellata, Thomson, Physis, ii. p. 901.

Hab. Costa Rica!.—Soutn America, Venezuela.

The punctuation of the elytra is similar to that of 0. sparsa, but rather denser;

the tawny tomentum is condensed into round spots, which clothe the elytra from near

the base to the apex, leaving a large lateral patch of whiter colour.

Distinguished from the allied O. cingulata (Say) and other similar species, by the

thorax being of the same width behind as before the lateral tubercle, and by the thicker

Group HIPPOPSINI.

Lacordaire’s “groupes” Hippopsides, Spalacopsides, and Ischiolonchides, combined,

form a natural assemblage of forms closely allied to Onciderini, but distinguished by the

contraction of the crown of the head and the deflection of the lower part (with the mouth)

downwards and backwards towards the prosternum—a peculiarity which is carried to an

extreme in some of the genera, such as Spalacopsis, one of the most eccentric forms in

the whole of the Longicornia. The less-specialized genera, such as Dorcasta and Bebelis,

connect the group with the Ataxiini. Hippopsini are equally well represented in

the Eastern and Western hemispheres, but they are most numerous in South-eastern

Asia and its islands (including the Philippines) and in Tropical America, a few only

being found in Africa, Tropical and Southern, and in temperate latitudes of America

and Asia. One genus, Calamobdius, occurs in Southern Europe.

HIPPOPSIS.

Hippopsis, Serville, Encycl. Méth. Ins. x. p. 336; id. Ann. Soc. Ent. Fr. 1835, p. 41.

The comparison of a large series of specimens from North America (Texas), Central

America, and South Brazil has led me to the conclusion that there is no valid difference

between this species and H. lemniscata (Fab.) from the United States. The apex of the

elytra varies in one and the same locality as to the amount of its prolongation ; and it was

only the silence of Fabricius as to there being any pointed prolongation in H. lemniscata

HIPPOPSIS.—DORCASTA. 129

that induced Serville to consider the Brazilian form distinct. I have not had an

opportunity of examining specimens from so far north as Carolina, whence the types of

H. lemniscata were obtained ; but some Texan specimens have the elytra quite as strongly

acuminate as others from Rio de Janeiro. H. griseola (Bates) differs in the head

being tumid behind the eyes, and H. prona in the great length of the head above, and

the greater prolongation and obliquity of the forehead. In markings all these four are

nearly identical ; and the slight differences of form of the elytral apexes is clearly of no

specific value.

Seven species have been described of this genus, which appears to be peculiar to the

warmer latitudes of America, one species occurring as far north as Texas. Bebelis

This group is equivalent to the subtribe Acanthoderite, formerly proposed by me to

include a host of genera, chiefly Tropical-American, which have a smooth pyriform

antennal scape, and distinct tubercle and groove on the outer side of the middle tibie.

All have completely divergent tarsal claws; but the intermediate cotyloid cavities are

not constant in the extent to which they are opened externally. I do not, however,

find them quite closed in Acanthoderes and the allied genera, as Lacordaire states to be

the case. ,

The two tufts of black hair side by side on each elytron and the general colour amply

distinguish this species from O. costaricensis ; the former character, however, it possesses

in common with 0. fasciculosa (Thomson), from which it is well distinguished by the

absence of tufts from the posterior part of the elytra and other characters.

Differs from all the preceding in being clothed with long hairs. The tufts of

short hair on the elytra are on each side about eight in number (including some of

minor size): three (the outermost very small) lie in nearly a transverse line in the

usual place near the base; the others are spread over the disk near, and a little

behind, the middle. The femora are excessively thickened.

A specimen, doubtless authentically named, in M. Sallé’s collection, represents a

species very closely allied to O. hispida; but Thomson’s description does not very

well apply to it, as it omits to mention the long hairs with which the insect is

clothed, and the numerous tufts of black bristles on the posterior part of the elytra —

near the suture. M. Sallé’s specimen is distinguished from 0. hispida only by its

lighter brown colour and by the very oblique truncature of the elytra.

Nine species of this distinct genus have been described, all Tropical-American. It is

a form which, with Myoxinus and allied genera, bridges over the interval between the

two groups Acanthoderini and Acanthocinini, the antennal scape being less evenly

clavate, with a tendency to flexuous outline of the under surface.

There is little to distinguish this genus from Alphus, especially from the section having

tuberculated basal crests on the elytra, The outline of the antennal scape is somewhat

different, not being flexuous beneath near the apex; and another minor character is the

bituberculated mesosternum. Four or five species are known in collections, all from

Tropical America but only one has previously been described.

A genus founded on a North-American species, the Lamia dasycera of Say, the only

one, according to Lacordaire, to which its’ characters apply. He places it in his

“groupe” Pogonochérides; but its structural characters and the facies of the insects

point rather to an affinity with Alphus and Myoxinus. The following Mexican species

is perfectly congeneric with £. dasycerus :—

Psapharochrus, Thomson, Syst. Céramb. p. 19; Lacordaire, Gen. Col. ix. p. 750.

Symperasmus, Thomson, Syst. Céramb. p. 19.

About sixty species of this genus are known, nearly all from Tropical America, a few

only existing in temperate latitudes in North America, Europe, and Northern Asia, and

in Tropical Western Africa. Notwithstanding the considerable diversity among its

species in important points of structure, or rather in consequence of this diversity, which

is too abrupt and irregular for systematic purposes, it is impossible satisfactorily to divide

the genus. At any rate the division into the two genera sanctioned by the high autho-

rity of Lacordaire seems to me impossible to be maintained, one of these two genera

-(Psapharochrus) comprehending forms like the European A. varius and the South-

Brazilian A. cylindricus, melanostictus, &c., which are among the most disparate the

old genus contained. One of the results of the narrow definitions which Lacordaire

- was induced to impose, as he confessed, is that some species are left out altogether,

without generic location ; and, in fact, if the genus is disintegrated, nothing less than

a very minute subdivision will satisfy the sense of natural grouping. For this there

is no adequate reason, as the genus, in the aggregate, is well defined and easily to be

recognized.

Belongs to a group of species in which the terminal joints of the antenne are much

faint longitudinal carine of the elytra, and thus connects it with the following species,

for which Lacordaire could find a place in no described genus. ‘Traces of hair-tufts at

the apexes of the third and fourth antennal joints indicate also a relationship to

Tetrasarus.

Thomson, in describing the first species of this form as a Discopus (a genus in which

the third antennal joint only has a thick tuft of hairs), said that it merited to form a

division apart. The tufting of the antennz, however, proves to be distinctive of two

groups of species of which well-defined genera can be formed, distinguished by the

general form of the body as well as by the antenne. There is a further distinction also

in the shape of the tufts, which in Discopus encircle the joint all round, and in Tetra-

sarus leave one side of the joints naked. The broad mesosternum in most of the

species is steeply declivous in front and bituberculated, as in Acanthoderes swederi; in

others it is unarmed.

The genus seems peculiar to Guatemala and the adjoining countries north and south.

Having since received specimens from Guatemala which accord better, both as to

colours and locality, with Thomson’s description of D. quadriscopulatus, it is necessary

This genus is necessary for the reception of a species which differs from Tetrasarus

in the fourth antennal joint being quite destitute of hair-tuft, and the third joint

furnished with a tuft which adheres only to the lower surface without embracing the

sides, as it does to a smaller or greater extent in Tetrasarus. From Jiscopus, in which

also the tufts are confined to the third joint, the genus differs (besides the different

shape of the tuft) by the form of the elytra, which are not depressed along the suture,

or furnished with a strongly elevated longitudinal carina. The following sole species

at present known of this genus is very differently marked from any of the numerous

species of Acanthoderes and allied genera.

1. Plagiosarus binoculus.

Fulvescenti-fuscus, elytris utrinque post medium macula transversa atro-fusca fulvo anguste marginata ; an-

tennis nigris, articulis basi (tertio quoque medio) carneo-griseis ; thorace tuberibus dorsalibus et lateralibus

validis conicis lineaque dorsali paullo elevata, interstitiis punctatis ; elytris mox a basi gradatim, post

medium citius angustatis, apice transversim breviter sinuato-truncatis, supra sparsim (versus basin aspere)

punctatis.

Group ACANTHOCININI.

In this group I propose to include Lacordaire’s Acanthocinides (with the exception

of a few genera which he associated with Exocentrus in one of his sections) and his

Colobotheides. With very few exceptions they are distinguished from all other

Lamiade by their elongate antennal scape, of which the undersurface is flexuous ; and

the great'majority of the genera and species are peculiar to America.

| LAGOCHIRUS.

Lagochirus, Erichson, Wiegm. Archiv, 1847, i. p. 144.

Lagocheirus, Lacordaire, Gen. Col. ix. p. 762 (1872).

A characteristic American genus. One of its species ranges over the whole of the

tropical zone, including the West Indies, and passes into temperate latitudes in North

America, and is found still further at Tahiti and other islands of the Pacific. The

others are local, by far the greater number being confined to limited areas in Central

America and Mexico. About a dozen species are known.

According to a specimen in M. Sallé’s collection, which is evidently correctly named,

this species differs from L. araneiformis, not only by the dark transverse markings of

the elytra being obsolete, but by the antenne being ringed with pale ashy, joints 3 to 6

being biannulate ; the whole upper surface is also minutely punctured, and the apex of

the elytra more sharply truncated. Mexican examples of £. araneiformis, especially

those of small size, have a tendency towards ringed antenne. A male specimen taken

by Mr. Belt differs from the above-mentioned Mexican example in being less punctured

towards the apex of the elytra, and connects the species with the L. longipennis.

Differs from L. obsoletus conspicuously by its much more elongated elytra; in colour,

but especially in the almost obliterated dark and light transverse markings of the poste-

rior part of the elytra, the two species agree, differing thus from nearly all their con-

geners. I have seen only males of either species. ‘The tubers of the thorax, both

dorsal and lateral, are obtuse.

A fine species, as large as L. rogersi, but distinguished from it by the complete

absence of tufts of hairs from the elytra. The coste of the elytra also are deficient,

except at the extreme base, the rest of the surface being thickly sprinked with round

black spots margined with grey. The lateral tubercles of the thorax are remarkable in

both sexes in being terminated by a long sharp point. In a female example in

M. Sallé’s collection the usual lateral black spot is nearly obsolete.

Horn, Trans. Am. Ent. Soc. viii. (1880), p. 119.

This tolerably well-defined genus of small Lamiade, allied to Lagochirus and Leiopus,

is also restricted to America. About fifty species are known; thirteen of which are

recorded from North America and a small number from the West Indies. None have

yet been described from temperate latitudes in South America or even from South

Brazil, whilst Central America is rich in species. Mexico and the adjoining regions

may be considered, therefore, as in the case of Lagochirus, the headquarters of the genus.

I suspect Erphea of Erichson (Wiegm. Arch. 1847, i. p. 144) to be synonymous with

Leptostylus, or at least to include the species with prominent mesosternum ; but no

author seems to have recognized the genus since it was described, and I have not seen

the species on which it is founded.

character is also furnished by the position of the dark median spot. on the elytra, which

does not reach the margin.

Differs from L. hilaris in being rather more slender and elongate in form, and in the

elytra being ashy brown for a large space at the base and apex, and white in an ill-

defined fascia a little behind the middle. The median lateral spot is also larger and

united to the subapical marginal spot, which latter is different in position from the

analogous spot in L. hilaris, being in a transverse line with short postmedian black

fascia. In one of M. Sallé’s two specimens there is an additional curved black mark

on each elytron near the suture behind the middle (as in L. hélaris), which is absent in

the second specimen.

The lower lobe of the eyes is smaller and much more finely granulated in this little

species than in L. leucopygus ; and the antennal scape is distinctly longer, reaching the

hind margin of the thorax ; on the other hand it recedes less than that species from the

typical forms of the genus in the sternal structure, the prosternum being distinctly

broader and nearly as broad as the mesosternum, the contrary being the case in

L. lewcopygus. In another member of this group of small ovate species, viz. L. ovalis,

the pro- and mesosterna are as large relatively as in L. transversus ; it would be difficult

therefore to find definite generic characters by which to separate the group from

Leptostylus, notwithstanding their differences of general form.

The species for which this new genus is instituted has very little general resemblance

to the rest of the Acanthocinini, its oblong, subcylindrical form and long pubescence

being unusual features in this group. The length and form of the antennal scape and

the perfectly closed exterior suture of the anterior haunch-sockets, however, leave us

in no doubt as to its position. On account of its short posterior legs and hind tarsi I

place it near Leptostylus; but it would probably be better ranged in the vicinity of

Ecyrus and Alphus.

Three extremely small species at present constitute this very distinct genus, which

resembles Leiopus and Lepturges in the form of the prosternum and anterior coxe, but

differs wholly from them in its convex oblong body, with gibbous thorax and elytra

marked with short elevated lines arranged in rows. The thoracic lateral spines existing

in two of the species are similar to those of the genus Dectes; but in a third species,

very similar to the other two, these spines are absent. The form of the scape is unlike

that of any other genus of Acanthocinini, approaching nearest that of Alphus.

This new genus is founded for the reception of three species from Guatemala which

partake of the characters of both Leptostylus and Leiopus, and cannot be included in

either without rendering their definition impossible. They have the broad pro- and meso-

sterna, the cristulated upper surface of the body, and short hind tarsi of Leptostylus,

with the general form, and particularly of the thorax, of Leiopus. In general form and

in the shape of the apices of the elytra one of the species much resembles Leptostylus

premorsus of the West Indies, though much smaller.

In structural characters this species does not differ essentially from Leptostylus

premorsus from Guadaloupe, which with its allies, differing from the typical forms of

Leptostylus in the lateral armature of the thorax approaching that of Lezpus, might

very well be referred to EHleothinus. The small tufts of black hair on the elytra

resemble the dark spots of certain Leiopi, especially L. variegatus (Haldeman), which

differs from other Leiopi in the width of the mesosternum, and in that respect approaches

Eleothinus.

The large sooty-black patch of the elytra is very ill defined (and paler) towards the

base, but sharply limited posteriorly, where its border forms a blackish line obliquely

directed posteriorly from the epipleura to the suture, leaving a large apical area of the

same yellowish-ashy colour as the underside of the body.

In its more typical species, viz. those which are conformable to A. latwm (Thomson’s

type), this is a well-marked genus, distinguished by its trigonal form of body, unarmed

thorax, and by the high centro-basal ridges and the lateral and dorsal carine of the

elytra. Many of the less typical species, however, degenerate in one or more of these

features. Nearly thirty species are known, all Tropical-American.

Although very closely allied to A. ewlophum, and having a similar high, sharply-

compressed centro-basal carina, this species offers a very different facies, due to the

much shorter and more triangular form of the elytra and the absence of the charac-

teristic pale vein-like markings which in A. ewlophwm are seen between the M-formed

it is at once distinguishable by the greatly prolonged outer angle of the apex of the

This genus forms part of a small group, which are allied to Alcidion, but are

distinguished by the thorax being armed with medio-lateral spines or tubercles. To

the group belong the genera Tithonus, Belesthes, Cleodoxus, Lathreus, Lophopaum, &c.,

most of which consist at present of one species only. In Hexacona these tubercles are

This genus belongs to the same group as the preceding ; but its robust form gives it

a totally different facies from that prevalent among the Acanthocinini, and it would

readily be mistaken for an Acanthoderes; the closed outer suture of the: anterior

acetabula, and the length and shape of the antennal scape, however, leave us in no

doubt as to its true affinities.

The dark brown rounded spots, which are sprinkled over the upper surface, cover the

numerous punctures of the elytra and others which exist also on the hind part of the

thorax; but there are similar spots without punctures on the occiput and thorax, viz. two

on the former and two each on the discoidal tubercles of the latter. The tubercular

granulations of the elytra, which are strongly marked near the base and accompany

the punctures nearly to the apex, are also dark brown.

LOPHOPGUM. 159

LOPHOPCEUM.

Lophopewm, Bates, Ann. & Mag. Nat. Hist. ser. 3, xii. p. 275 (1863).

The typical species of this genus resemble the Leéopi and the shorter species of

Alcidion, having similar capilliform, slender antenne, and oblong or subtrigonal, mode-

rately convex form of body, free from inequalities and fasciculated sete: from both

they are distinguished by the acute median lateral tubercles of the thorax. The elytra

have short centro-basal elevations or ridges, sometimes surmounted by a pencil of hairs ;

and the epipleuree, although vertical towards the base, have not carinate edges. The

antennal scape is as long as, or longer than, the third joint, and is very slightly flexuous

beneath ; the pro- and mesosterna are moderately narrow; and the hind tarsi have a

short basal joint, as in Alcidion. Unfortunately it is impossible to fix definite limits

between these normal species and others, such as L. barbiscapum and L. cultriferum,

which depart widely from the types in facies and in many structural details. The

species just mentioned are of much larger size and more robust form, with antennal

scape strongly flexuous beneath and elytra more or less roughened with tubercles or

hispid with fasciculated tufts of hair—L. cultriferum agreeing with the typical species in

the capilliform and nearly naked antenne, whilst L. barbiscapum differs by the stouter

filiform shape of these organs, which are rather densely ciliated beneath. These differ-

ences might justify generic separation ; but intermediate species, such as L. scopiferum

(having the facies and robust antenne of L. barbiscapum, but with unciliated antennal

joints and smooth elytra) and L. saronotum, completely bridge over the interval.

L. acutispine is the only known species which has distinct lateral carine.

About a dozen species of Lophopaum are known, all Tropical-American.

The true position of this genus, which differs so strikingly from its allied genera in

the elegant tufts of hair which ornament the antenna, is evidently here, many parts of

its structure having a close resemblance to those of Lophopwum scopiferum and barbi-

scapum. The anterior acetabular sutures are tightly closed; but the forehead is more

prolonged below the eyes than is usual in Acanthocinini. Four species are known from

Tropical South America and San Domingo.

The slender form, voluminous lower lobe of the eyes, and narrow pro- and mesosterna

indicate the close affinity of this genus to Anisopodus, from which the thoracic tubercles

and long hairy elytra amply distinguish it. The form of the lateral tubercles of the

thorax differs from that of the preceding genera, the apex of the protuberance forming

a retrocurved point as in Leiopus. Besides the two large obtuse tubercles on the anterior

part of the disk of the thorax, there are two others, much less elevated, on the

posterior part.

The long, erect, and rather fine sete of the elytra are implanted each in a puncture,

which, along the suture, is accompanied by an elevated granule. The elytra are

depressed behind and on the outer sides of the centro-basal elevations; and the apical

truncature is slightly oblique, sinuate, with the exterior angle considerably prolonged

and dentiform.

Upwards of twenty species of this well-marked genus have been described, all Tropical-

American except one, which occurs in the temperate zone of South America. The most

conspicuous distinguishing character is the length of the hind legs, which in some species

assume almost monstrous proportions. The body is elongate and depressed, free from

inequalities above ; the thoracic spine is small, and situated near the hind angles; the

pro- and mesosterna are narrow, the haunches globular, and the forehead very short,

prolonged but slightly below the voluminous lower lobes of the eyes.

ANISOPODUS. . 163

Similar in size and general appearance to A. phalangodes, but widely different in

many points of structure. The thorax, instead of being rounded at the sides, with the

lateral armature standing out abruptly as a distinct spine, is of trapezoidal form, with

oblique and perfectly rectilinear sides, which contract only behind the lateral armature,

so that the apex of the tooth or spine is continuous with the lateral margin. The apex

of the elytra is also differently truncated and toothed, the sinuation being narrow and

very deep, and the sutural angle forming a projecting tooth as well as the external one,

although shorter. The small black spots of the elytral surface are much smaller and

more irregularly scattered. The hind femora in the female do not reach the apex of the

elytra.

Hab. Costa Rica (coll. Bates).

In outline this species does not materially differ from L. scriptipennis ; but the posterior

femora, though a little longer than the body, are not perceptibly clavate, being gradually

and moderately thickened. This structure is foreign to the typical species of the genus ;

but the elytral epipleure are distinctly vertical, and the facies of the insect is that of

Anisopodus, rather than of Lepturges. The coloration is remarkable, the whole under-

surface, the head, antennz, and legs being of a rather clear, tawny yellowish, which hue

(a little Jess clear) forms the ground-colour of the thorax and elytra, on which are longi-

tudinal streaks and spots, and on the elytra a median strongly zigzag belt of a dark-

brown hue. The epipleure of the elytra have dark-brown patches; and there is also a

short broadish vitta on the disk near the apex on each side.

Hab. Mexico, Juquila (Sal/é).

This charming little species has more the form of a Lepturges than of an Anisopodus ;

but the vertical epipleure of the elytra, separated from the flattened disk by a distinct

though blunt keel, prove that it belongs to the latter genus. The ground-colour is a

uniform bluish grey; and the numerous black spots of the elytra are sprinkled nearly

at equal distances over the surface.

The markings of the elytra in this pretty little species form an elegant pattern,

difficult to describe in an intelligible manner. The ground-colour is a pinkish tawny,

converted into grey, in places, by the condensation of the fine hoary pubescence, which

latter forms near the black outer border and in the middle of the black apical area

various transverse or oblique and zigzag lines; an obscure dark brown patch is also

seen on each side of the suture behind the scutellum. It is the only species known in

which the angles of the apical truncature of the elytra are not spinose or produced,

and in this respect does not differ from the typical Lepturges.

The minute dentiform projection existing, in one species at the apex of the sixth, and in

another of the fifth, antennal joint is of similar nature to that of the sixth joint in the

males of Lagochirus. The same curious structure distinguishes also the North-American

genus Canopeus (Horn) and the South-American Amniscus ; but in the last-named it is

on the third instead of the sixth joint. Pattalinus differs from all three by the spined

thorax and smooth surface of the body. There is so close an affinity in all other respects

between the two species described below, that I am inclined to disregard the curious

difference in the situation of the armature of the antenne, and include them in one

genus.

viii. p. 126 (1880).

Dr. Horn has improved the definition of this genus by adding to the characters I

originally gave a further one drawn from the pro- and mesosterna, both of which, as he

correctly states, are very narrow and barely wide enough to separate the coxe. In the

more typical species the front of the head is short, and the lower lobes of the eyes

voluminous as in Anisopodus; the epipleura of the elytra, however, are not strictly

vertical or separated from the dorsal surface by a sharp line; and the hind femora are

linear or but obliquely thickened. The less typical species have clavate femora, and

in some cases are scarcely distinguishable from Leiopus. Inall, the thorax has a sharp

lateral spine, either close to, or a short distance from, the hind angles, the space

between the angle and the spine, in the latter case, being deeply sinuate.

About fifty species, including those about to be described, are known, all from

Tropical and North America.

A Mexican specimen from the Sallé collection agrees closely with the typical example

from the Upper Amazons; but other Mexican specimens, and all those I have seen from

Chontales, differ in the dark spots of the elytra (especially those on the sides and near

the shoulders) being less connected, and in the basal spot (near the scutellum) forming

an elongate streak. These latter make some approach to L. fragillimus from the

Amazons, to which I formerly referred them; but on the examination of a long series

of both sexes I am inclined to consider them quite distinct from that species..

The few long soft hairs which spring from the surface of the elytra are of different

to indicate any generic distinction from Lepturges. The species is closely allied to

L. mixtus, having a similar form of thorax; but the elytra offer no trace of truncature.

The black lateral mark of the elytra, seen from above, looks like a large semioval spot

with its convex side approaching the suture; but it consists really of a thick and not

well-defined flexuous streak, which commences under the humeral angle, runs for a

space along the epipleura, and then curves towards the disk, terminating beyond the

middle without reaching again the lateral margin.

This genus bears a similar relation to Lepturges as Sporetus to Nyssodrys, being

distinguished from its allied genus by the bristly clothing of antenne and elytra.

But it has a further distinctive character, peculiar to itself, in the terminal segment of

the abdomen in the female being lengthened to form a sheath to the ovipositor, in a

way not seen in any of the allied genera. Without projecting much beyond the tips of

the elytra, the segment is longer than all the remaining segments taken together, and

is nearly of equal width from the base to the apex, the latter being entire and rounded

in both the dorsal and ventral valves.

J should have referred the species described below to the North-American genus

Graphisurus (Kirby), the characters of which have been recently established in a satis-

factory manner by Dr. Horn (Trans. Amer. Ent. Soc. viii. p. 129), had it not been for —

the difference in the ventral plate of the ovipositor, which, in Graphisurus, is described

as emarginated.

This genus is necessary for the reception of Lepturges letabilis, which differs from

Lepturges in its wide pro- and mesosterna. In the form of the head and antennal scape

it has great resemblance to the genera allied to Anisocerus; but the length of the

scape, and especially the perfect closure of the anterior acetabular sutures, show that its

right place is in the Acanthocinini group.

Also an exclusively American genus, but having a more northerly distribution than

any of the preceding genera of this group. Its head quarters appear to be Mexico,

one species ranging into the middle states of North America. The following are the

only species known.

Mexican specimens seem to be intermediate in the degree to which the thoracic

spines project from the sides, and to connect the two species (or local forms) spinosus

and texanus, the only difference between which, according to Leconte’s description, is

that in spinosus the spines stand out at an angle from the sides, and in teranus are

continuous with the lateral margin. Dr. Horn reunites D. texanus to spinosus.

According to specimens bearing the name of this species in M. Sallé’s collection, this

species is extremely variable in size, colour, and markings, the extreme forms being :—

(a) robust (64—7 lines), uniform ashy grey, varied solely by fuscous tips to the antennal

joints, elytra broad at the shoulders and tapering thence to the apex, thorax without

inequalities except a faintly raised dorsal line; (0) less robust, narrower, sublinear,

ashy brown, varied with dark brown and pale ashy spots, elytra with a pale ashy

narrow fascia forming a circumflex near the middle of each elytron, thorax uneven.

In all the varieties the apex of the scape beneath is recurved, forming a broad denti-

form projection.

D. mexicanus, besides its more cylindrical shape and the markings of the elytra, by the

antenne being rather densely clothed to the apex with short hairs, and by the narrower

and more acute spine of the antennal scape, which is besides preceded by a deep.

sinuation in the under surface.

Hab. Nicaracua, Chontales (Belt).

I refer this species to Hdopeza with much hesitation. In colour and markings it lacks

the chalky-white spots characteristic of the genus; and in structure it differs in the fore-

head being broader, with smaller and more rounded eyes, and by the pro- and mesosterna

being both distinctly wider, the latter quadrate and not perceptibly narrowed behind.

The femora, however, resemble those of @dopeza in being pedunculated and rather

strongly clavate. It is doubtful whether the female has an elongated ovipositor; the

specimens before me may, however, be males.

Chontales specimens differ from the typical Cayenne form in the twin velvety spots

Ecuador.

T. melancholicus differs from the other species of the genus in the considerably shorter

forehead and lower lobe of the eyes.

CHAETANES.

-Chetanes, Bates, Ann. & Mag. Nat. Hist. ser. 3, xiii. p. 45 (1864).

The following is the only described species of this genus, which is very closely allied

to Trypanidius, differing chiefly in its bristly surface and the presence of centro-basal

tufts on the elytra, in which it resembles certain species of Lophopeum.

1. Cheetanes setiger. (Tab. XII. fig. 8.)

ATRYPANIUS.

Atrypanius, Bates, Ann. & Mag. Nat. Hist. ser. 3, xiii. p. 47 (1864).

This genus has been incorporated with Trypanidius by Harold and Gemminger in

the Munich catalogue; but I think it has an equal title to generic distingtion to most

other genera in this difficult group. Its differential characters, as I explained in founding

the genus, lie chiefly in the plane mesosternum and the very short ovipositor. The

elongated forehead and elongate-oblong lower lobes of the eyes and short basal joint

of the hind tarsi it possesses in common with Trypanidius, and the broad mesosternum

in common with Nyssodrys. The more convex species of Nyssodrys approach it very

closely, the length and oblong shape of the lower lobe of the eyes being the chief point

of distinction; and even this shades off almost imperceptibly from species to species.

In Nyssodrys, however, the ovipositor is always long, projecting beyond the tip of the

elytra.

In this and the following species the lower lobe of the eyes is rather less parallel-sided

than in A. conspersus, although the lower end is truncated; but in two undescribed

Brazilian species, very closely resembling A. sedatus, the eye is formed exactly as in the

type of the genus. Nicaraguan specimens resemble those from the Amazons in their

dark brown and tawny-brown colours; but a numerous series, taken by Mr. Champion

at San Gerénimo, are much variegated with light grey and distinct tawny and blackish

spots, approaching in this respect very remarkably A. conspersus. All the Mexican

specimens, although similar to those of Nicaragua in colours, have a structural pecu-

liarity in the apices of the elytra being so obliquely truncated that each elytron seems

to terminate in a point.

NYSSODRYS.

Nyssodrys, Bates, Ann. & Mag. Nat. Hist. ser. 3, xii. p. 149.

In addition to the characters enumerated in my original definition of this genus, may

be now mentioned the broad pro- and mesosterna, and the short, generally obtuse and

often obsolete lateral spine of the thorax, which is distant from the hind angle and not

separated from it by a deep sinuation of the sides. The ovipositor of the female in all

the numerous species projects, generally to a moderate degree, beyond the apex of the

elytra.

Nearly fifty species are known of this genus, which appears to be confined to the

NYSSODRYS. 179

tropical zone of America; at least Dr. Horn, in his recently published excellent revision

of the Acanthocinini of the United States, does not mention the genus.

Belongs to Myssodrys on account of the considerably elongated ovipositor of the

female; but the lower lobe of the eyes is as long relatively as in Atrypanius, with the

difference that it is much narrowed below. A long subtriangular lobe seems to be the

rule in the typical species of Nyssodrys; but the character has not much systematic

' importance.

with gradually and only slightly thickened femora, long first tarsal joint of hind tarsi,

very broad pro- and mesosterna, and possess in the females long projecting ovipositors.

The very considerable width of the mesosternum necessitates the removal of this

and the three following species from the genus Lepturges, in which I had originally

placed them, and to which they seem naturally to belong by their slender form and the

style of their markings and coloration. The lateral spine of the thorax, always well

developed in Lepturges, in WV. letifica is wanting. All the specimens taken by

Mr. Belt appear to be males; at least none of them shows a trace of an ovipositor.

A single example from Mr. Belt’s collection agrees with specimens from the Amazons

in every respect, except that the elongated black spots of the elytra parallel to the

suture are joined together, and the posterior one is also joined to the sutural border.

As the elytral spots are somewhat variable in the Amazonian examples, I have little

hesitation in referring the Chontales insect to the same species.

The antenne in this and the following species are but little longer than the body in

either sex, and perceptibly thicker than in A. dorsalis (the type of the genus). These

features and the setose surface of the elytra bring them within the definition of the

genus Urographis, from which, on the other hand, they differ much in the form of the

thorax and in facies. |

This prettily marked species accords in the generic characters at present accepted

neither with Astynomus nor Urographis. In its general form, however, it resembles

the typical species of the former genus much more closely than any other of this

perplexing group. If it be thought desirable to separate it generically, the following

two species will have to be associated with it.

The lateral carina of the elytra taken alone would necessitate the location of this

species in the genus Eutrypanus ; but all its other characters are those of Astynomus,

and the length of the ovipositor and its cleft lower valve are unlike any thing known

in Hutrypanus. In its form and markings it most resembles 4. melanophilus (Chev.)

of Venezuela; but it is much darker in colours. I have adopted the MS. name given

to it in the Sallé collection.

OLENOSUS.

Olenosus, Bates, Trans. Ent. Soc. 1872, p. 205.

The male only was known when I drew up the characters of this genus ; since then,

having seen the female, and found that it has an elongated ovipositor differing very

little in relative length and shape from the same organ in Acanthocinus, it has become

necessary to remove the genus from the neighbourhood of Oreodera, where it was

originally placed, into that of Acanthocinus and Astynomus. It is amply distinguished

from both genera by its strongly clavate antennal scape and the long and denticulated

anterior tibie of the male. The sternums, both of the pro- and mesothorax, are much

narrower between the coxe than in the allied genera, and approach in form the same

parts in Leiopus and Lepturges.

Four species are known, all Tropical-American. With this commences a series of

The insect for which this new genus is instituted bears no resemblance in facies or

markings to any of the numerous species of Colobothea, Synchyzopus, and Carterica,

which it approaches in its elongate and laterally-compressed form. The form of the

thorax is also peculiar, but bears some resemblance to that of Synchyzopus histrio,

excepting its tuberose surface.

Hab. GuatemaLa, Panzos (Champion).—SovutH America, Colombia}.

This species differs from the type forms of Carterica in its shorter antennal scape and

in its elytra tapering towards the extremity instead of being parallel or slightly dilated

towards the apex. In these respects it accords better with Synchyzopus. The terminal

abdominal segment in the male is remarkably elongated and deflexed, with cleft apex

of the dorsal plate, and the large side pieces of the genital apparatus protruding between

this and the ventral plate. The dorsal plate in the typical species C. cinctipennis is also

notched, but in a much lesser degree.

2. Carterica pygmea.

‘Seventy species of this highly characteristic Tropical-American form of Lamiid

Longicorns have been described. They are far more numerous and varied in Equatorial

South America than in the northern part of the Neotropical zone; and none appear to

be found in the West-India Islands, or in the pampa region south of Brazil. The

genus belongs to the Acanthocinini group in all essential points of structure, differing

chiefly in its elongate and laterally-compressed shape of body, the tendency to this

modification of form exhibited in many of the genera allied to Astynomus here

_ reaching its acme. The high epipleure of the elytra are always limited above by a

distinct elevated line or carina. The species are all of medium or large size, and prettily

varied with tomentose spots or bands.

Hab. Nicaraeva, Chontales (Belt).

In the description above cited the form of the terminal abdominal segment is

erroneously described, owing to my having mistaken a bifid process forming part of the

genital organs as the end of the dorsal plate. The parts are nearly hidden by hairs,

rendering it difficult to ascertain the real shape. As several species, closely allied in

the ashy-white macular tomentose patches of the elytra, are distinguishable chiefly by

the form of this segment in the two sexes, I add here an amended description.

only by the separation of the central dorsal vitta of the thorax into two widely separated

stripes and the different structure of the sheath of the female ovipositor, but by the

macular ashy belts of the elytra being all followed by belts of equal width of the griseous-

black ground-colour.

Group TAPEININI.

This group, equivalent to the “ Groupe Tapeinite ” of M. Thomson, is retained, pro-

visionally, for the anomalous genus Tapeina, the true position and affinities of which it

is difficult to determine. M. Thomson, in his ‘Systema Cerambycidarum,’ in 1864,

placed it at the end of the Lamiide, after the Saperdini; and in my review of the

Longicorn Coleoptera of the Amazons, in 1866, I treated it as a separate group having

affinity with the Desmiphorini and Exocentrini, stating that these curious insects

appeared to be “abnormally flattened Exocentrine.” Lacordaire, in the ninth volume of

his ‘Genera,’ in 1872, disagreeing with these views regarding their affinities, placed them as

a Groupe Tapeinite among a series of Old-World forms, and in close connexion with Enotes

and Enicodes, forms peculiar to New Caledonia, with which, indeed, they agree in their

chief structural characters. I am now inclined to doubt that Tapeina has any close

affinity with the Exocentrini, the anterior acetabular sutures being less tightly closed

than they are in the true members of that group; and I think their true place is near

Eupogonius and allies in the Desmiphorini.

Group HEBESTOLINI.

This group corresponds with Lacordaire’s “Groupe” Hébestolides. It forms the

connecting link between such genera as Hstola among the Pogonocherini and the

Phyteeciini, having the toothed tarsal claws of the latter and all the other characters

and facies of the former. According to Lacordaire, the Hebestolini are distinguished

from the other groups having toothed tarsal claws by the closure of their intermediate

acetabula. ‘This is a character of extremely doubtful application ; and the difference

in the form of the acetabula between Ewmathes of this group and Drycothea of

the group Calliine is so slight that, the great resemblance between the species of the

two being considered, it seems in the highest degree artificial to place the two genera

- In separate groups.

Eumathes cuprascens, Bates, Trans. Ent. Soc. 1873, p. 238.

Hab. Nicaracva, Chontales (Belt).

The middle acetabula are slightly more open externally than in Humathes undatus,

and, in fact, are of the same form as in Drycothea salle. ‘This species ought therefore,

according to Lacordaire’s views, to be removed from the Hebestolini to the Calliini

group. But, on the other hand, the middle tibize are notched and grooved, and the

mesosternum convex and keeled, as in Eumathes.

CYMATONYCHA.

Cymatonycha, Bates, Trans. Ent. Soc. 1873, p. 234.

The following is the only known species. The tarsal claws in this genus have only a

rudiment of dentiform projection at their base.

Hab. Guatemaia, Chacoj (Champion) ; Nicaracua, Chontales (Belt?).

Group CALLIINI.

I adopt this group from Lacordaire’s arrangement, but should be disposed to modify

it by transferring to it Eumathes from the group Hebestolini. With tarsal claws

similar to those of Oberea and a number of other genera belonging to the old sub-

family Saperdine, it differs in its totally different facies, owing to the short and

generally ovate forms of its species, and the thorax being ovate, with most frequently

a distinct lateral tubercle.

DRYCOTHEA.

Drycothea, Thomson, Physis, ii. p. 145 ; Lacordaire, Gen. Col. ix. p. 908.

One Mexican species only has been described. Others have been discovered by

Champion in Guatemala, and are apparently common insects; so that it is probable the

genus is a numerous one in Central America.

2. Drycothea stictica.

Estole perforate simillima, sed antennis brevioribus. Elongata, breviter setosa, ochraceo-fusea, elytris maculis

parvis irregularibus (plerumque transversis) passim variegatis, antennis pedibusque griseo-nigris, illis

articulis basi griseis; thorace utrinque tuberculo laterali parvo acuto, dorso sparsim grosse punctato ;

elytris usque ad apicem striato-punctatis, interstitiis hic illic paullo elevatis, apice singulatim obtuse

194 . LONGICORNIA.

Closely allied to D. stictica, but smaller, and clothed with uniform ashy-brown

pubescence, varied only by the darker punctures. The thorax is also rather more finely

and closely punctured; and the femora are of a pale testaceous-yellow colour. The

last-mentioned feature is somewhat variable; in some examples the femora are wholly

pale, with the exception of the tips; in others the upper and lower edges are dusky as

well as the tips. |

4, Drycothea cribrata.

Parva, nigro-fusca, lineolis vel lituris parvis fulvis sparsim variegata ; thorace crebre grosse punctato; elytris

_ setis incumbentibus rigidis vestitis, confluenter crebre punctatis; antennis robustis, articulo tertio quam

scapum multo longiore, 4° 6° basi griseis, 8° toto 10° basi testaceis.

Long. 22 lin.

Hab. GuatEMaa, Teleman (Champion).

The thoracic spine, though distinct, is not so long and acute as in J. stictica. The

elytra are thickly punctured throughout, and the punctures often confluent; but, with

the exception of the sutural stria, there is little tendency to linear arrangement as in

the other species. The mesosternum is not prominent, but slightly concave in the

middle.

Group TETRAOPINI.

This group forms a natural assemblage of genera, distinguished by the obliteration

of the connexion between the lobes of the eyes and the consequent existence of two

eyes on each side of the head. The tarsal claws in the majority of the genera have a

tooth at their base; but in others they are fissile. The group is equivalent to Lacor-

daire’s “Groupe II.” of his ‘“ Phyteciides vraies,” and is distributed over the warmer

parts of America, Africa, and Asia, being least numerous in Africa, and having one

representative in Europe.

Hab. Mexico}, Cordova (Sallé), Almolonga (Hége); GuatemMaua, Zapote, San Juan

(Champion).

This common species varies in length from 3 to 6 lines, and is known in most collections

as Phea divisa (Chevrolat) ; but it appears nowhere to have been described under that

name. In Pascoe’s description the thorax is stated to have a black spot in its centre ;

but it is not mentioned that the spot covers a central boss. This feature is more

strongly marked even than in Ph. saperda, the sides of the umbo being vertical and

sharply defined, and the surface more or less punctate. The femora vary in colour,

being sometimes black like the rest of the legs and the abdomen, and sometimes partly

or wholly red. In one of Mr. Hége’s examples the thoracic umbo is red, like the rest

of the surface.

4, Phea lateralis.

P. acromele proxime affinis, at differt thoracis umbone minus elevato, lateribusque infra nigris. Nigra, subni-

Closely allied to P. acromela, but different at first sight in the yellowish instead of

bright-red colour of the head and the thorax, and in the centre of the latter being tra-

versed by a broad black vitta from base to apex. The central umbo is also distinctly less

elevated and its sides less vertical and sharply defined. The flanks of the thorax (above

the insertion of the legs) have a broad black stripe. The punctuation of the elytra is

nearly the same as in P. acromela, i. e. strongly impressed throughout, in distinct lines

over the basal half and irregular over the apical portion. |

Closely allied to P. scapularis, and resembling it in colours; but the fulvous stripe

at the shoulders is expanded into a large acutely-triangular spot, extending nearly or

quite as far as the suture; and the lateral black vitta of the thorax lies on the flanks,

leaving the whole dorsal surface of the tawny-yellow hue; in P. scapularis the black

stripe of the thorax extends to the upper surface, and the central yellow vitta is rather

narrower. P. semirufa has also a conspicuously longer thorax, with the umbo margined

on the sides.

A species much more elongate and linear, or cylindrical, than P. saperda, and distin-

guished further by the bright red colour of the head, thorax, and elytra, the latter having

the apical portion, to the extent of rather less than one fourth of the length, black.

The elytra are rather strongly lineate-punctate, with the apical part less deeply 2 and

more irregularly punctured.

Approaches very near the common United-States species T. tetraophthalmus in the

sides, and punctate and shining; but it differs from that species in the obtuse lateral

margins of the umbo being slightly elevated, even in the middle, and not continuous

The second (lateral) spot of the elytra, absent in 7. thermophilus, is in this species

large and transverse, sometimes joining the subsutural spot, and thus forming an angular

fascia. The thoracic umbo is decidedly narrower, and much more sharply limited on

the sides, which are also separated from the rest of the disk by a distinct sulcus; its

surface is thickly punctured and hairy. In some respects it approaches 7. collaris of

New Mexico, in which, however, the thoracic umbo is opaque and impunctate. The

variety with black femora is named nigripes, Chev., in the Sallé collection.

According to the description, this species must be closely allied to the North-American

T. discoideus, Lec. (Journ. Ac. Phil. ser. 4, p. 26); but Dr. Horn, in his recent revision

of the North-American species, keeps them separate, and he has given me the result

of his examination of Dr. Leconte’s type specimen, which confirms the view that the

insect here cited is really the 7. umbonatus of that author. The thoracic umbo is very

sharply elevated on the sides. The specimen figured is from Mexico.

Group PHYTACIINI.

In this group I propose to include Lacordaire’s Phyteeciides vraies, Amphionychides,

and /Erenicides, a numerous assemblage of forms in which the Saperda type of Lamiide

reaches its highest development. The tarsal claws are nearly always fissile ; 7. e. the basal —

tooth is long and acute; and the elytra in the more typical genera are carinated on the

sides. Some of the species have tufted antenne; and others exhibit extraordinary |

mimetic resemblances.

In this genus, omitted in Lacordaire’s great work ‘ Genera des Coléoptéres,’ the claws

are bifid as in Phytwcia; but the body is long, subcylindrical, or linear, as in Oberea, to

which some of the species bear a great general resemblance. The proportions of the

ventral segments are as in Phytecia. The head is not retractile, and is often very tumid

behind the eyes. Six species have previously been described, from the United States

and Mexico.

1. Mecas senescens.

Compared with a series of Texan specimens of UW. inornata, this, species differs in

being decidedly narrower and more parallel-sided ; the number of glabrous specks on

the disk of the thorax seems also to be a good specific character. |

Hab. Mexico, Guanajuato (Sallé).

This species was ticketed Saperda immaculicollis by Sturm. I cannot adopt the

specific name, as the thorax has a more or less variegated appearance, according to the

density of the pale pubescent stripes, and the interspaces are sometimes partially fuscous.

The abdomen is unicolorous dark cinereous in both sexes, a character which distinguishes

the species from the two following.

Both sexes have the Lampyris-like pale lateral patches of the three terminal seg-

ments of the abdomen.. The pale rufous suture and margins of the elytra seem to

form also a constant character. The apex of the elytra is still more obliquely and

sharply truncated from the sutural angle. Four examples taken by M. Hoge at

Misantla are perfectly uniform.

PANNYCHIS.

Pannychis, Thomson, Syst. Ceramb. p. 127.

A genus very closely allied to Mecas, but with a difference of habit, due chiefly to

its broader and more depressed form of body and different coloration. Its chief struc-

tural character is furnished by the vertical epipleure of the elytra, which are sharply

defined from the dorsal surface, except towards the apex, where the sides are somewhat

dilated. In some species the dorsal surface of the elytra is ribbed. Thomson described

two species from Mexico. If I have determined the second one (P. melanophiloides)

correctly, it does not belong to the genus, but to Alampyris, described further on.

The fulvous belt of the elytra occupies about one third their length ; and the colour

extends along the suture towards the scutellum. The antennz and abdomen are entirely

black. Although the male example above described has no dorsal coste, it has

rudiments of the same in two narrow impunctate lines extending nearly the whole

length.

Very similar to P. ducalis 2, but differing in many points. The thorax is not

broadly dilated in the middle, but only slightly widened behind the middle, and it

appears longer and narrowed anteriorly. The elytra, instead of being entire at the apex,

have a rather deep sinuation near the suture, and the fulvous fascia is narrow, exactly

median, and the tawny colour is not continued along the suture towards the scutellum.

The central spot on the third and fourth ventral segments, and the fulvous fourth

antennal joint, are also distinguishing characters. .

in South Brazil to Guatemala.

ANTODICE.

Antodice, Thomson, Syst. Ceramb. p. 128 ; Lacordaire, Gen. Col. ix. p. 900.

A genus very closely allied to Hrenica, differing only in the closer approximation of

the eyes on the crown, and the rounded, instead of acute, apices of the elytra. The

long antennal scape, which distinguishes the typical species of Hrenica, is not constant

in that genus; otherwise it would be a good differential character, the scape in Antodice

being short. Neither is the notch of the middle tibie, pointed out by Lacordaire as

distinguishing Antodice, here of systematic value, as it is well developed in Hrenica

hirticornis.

The geographical range of Antodice is similar to that of Hrenica; but it extends a

little further north, into Mexico.

208 LONGICORNIA.

ERANA.

Erana, Bates, Ann. & Mag. Nat. Hist. ser. 3, xvii. p. 481 (1866).

Although widely separated from it by Lacordaire, this genus differs from Essostrutha

only by the much slenderer antenne, the greater length of the scape, and the fringe of

hairs above, as well as beneath, the joints. The difference in the width of the head,

and its consequent more or less retractility within the thorax, is very slight, the head

being relatively broader in Hrana than in Kssostrutha. The Brazilian species Saperda

triangularis (Germar), which I had referred to the genus, must be removed from it.

The following Central-American species differ somewhat from the generic type, E. cine-

ticornis, in the greater length and slenderness of the antenne, of which the third joint

is very long and slightly curved; but in the length and shape of the scape and pilosity

of these organs they agree very well with £. cincticornis.

After a careful examination of the large series of Essostruthe in the Sallé and other col-

lections from Mexico, and the numerous specimens sent by Mr. Champion from Guate-

mala, I am disposed to disagree with Thomson and Lacordaire that all the varieties they

mention belong to one species. If they are one species, it is one of those cases in which

the varieties are different and constant in different localities. Newman's description

applies to one of the rarest of the varieties, in which the head and thorax are “rufa”

and the elytra “cana,” with black lateral border and the thighs red. Specimens in the

Sallé collection agree pretty closely with this description ; and I find them associated

with colour-varieties quite different from what I consider to be allied species. In

E. leta the elytra are unicolorous, either grey, greyish black (sometimes with paler

suture), or deep black. The colouring of the vertical epipleuree is peculiar and distinc-

tive of the species,—the basal portion having, in all the varieties, a wedge-shaped vitta

red or reddish ashy, the rest of the epipleuree being of the same colour as the dorsal

surface—except in the grey specimen, where the angular upper edge has a long blackish

streak, answering to Newman’s “ margine laterali nigra.” The abdomen beneath and

the episterna are always orange-red or tawny, the centre of the breast and abdomen

grey ; and the round black spot, distinctive of E. fimbriolata, on the flank of the pro- |

thorax, near the socket of the haunch, is almost always absent. There appears to be

in E. leta no sexual distinction in colours as in E. fjimbriolata.

I have adopted for this species the MS. name given to one of its varieties by Chevrolat.

The short description of A. aldina published by Pascoe is evidently drawn up from the

male of this or an allied species; but the colour “ griseo-alba ” does not apply to any

of the examples I have seen ; and it is further stated to be from Guatemala, from which

country no insect answering to the description is contained in the collections of Sallé

and Champion.

The specimens from Juquila and the Pacific coast are more slender than those of

Central Mexico, and the males often have a pale fuscous spot at the apex of the elytra.

The only specimen I have seen which answers to Lacordaire’s brief description,

“rouge de cinabre avec quatre points sur le prothorax et le sommet des elytres, sur

have a male specimen, from a small collection made by Sumichrast in Tehuantepec, which

I believe to be the source whence M. Sallé’s example was obtained ; and it differs in so

many points from the males of both £. leta and jimbriolata, that it cannot be considered

other than a distinct species. Both males and females are much more elongate than the

species just cited, and both are of a rich cinnabar colour; the male has only two (the

hinder pair) thoracic spots, and the elytra are free from black marks, except on the

humeral callus; the female has four spots on the thorax, and a broad apical and narrow

lateral margin (not reaching the shoulders), black; the flanks of the prothorax show

the small black spot in both sexes. The antenne in the male are long and robust.

This species belongs to Essostrutha rather than to Erana, where I was inclined at

first to place it—the robust, filiform antenne, ciliated beneath and not above, and the

shorter and thicker scape bringing it within the definition of the former genus. In form

and colours it resembles Erana leuconoe. ‘There is no colour-difference between the

The combination of enlarged head in both sexes, excessively developed in the female,

and the absence of the usual sharply defined line or carina on the sides of the elytra,

effectually distinguishes this genus from Amphionycha, with which it agrees in the pro-

portions and clothing of the antennal joints. The pubescence which clothes the upper

surface of the joints is very short and incumbent. The body is much less elongated

than is the rule in Amphionycha. The enlarged head alone would not be a sufficient

generic character, as it is frequent, sometimes in the female only, in Amphionycha.

Three species of the genus are known, from Central America and the northern parts

of South America.

Amphionyche except the long hair-tufts on the fifth and sixth antennal joints; it

must be added that it also differs in the elongation of the fourth joint, which is but little

shorter than the third. The sides of the elytra are more or less distinctly carinated ;

and the high and vertical epipleure are furrowed with longitudinal punctured strie.

Seven species of this genus have been described, all Tropical South-American. The

pair of curious horn-like projections from the forehead are in some species reduced to

obtuse tubercles; were they absent altogether, scarcely any thing would remain to

distinguish the genus from Amphionycha. The lateral carina is sharply limited, more

or less curved, sometimes even flexuous, and terminating abruptly at three fourths the

length of the elytra.

This genus was introduced to science under the name above given by Dejean in his

‘Catalogue des Coléoptéres.’ Unfortunately it remained for many years without

published characters ; and as Dr. Leconte, in 1852, was thought to be the first to give a

generic formula, which unfortunately excludes nearly all the species before and since

described under the name, Dr. Horn has recently claimed for this later definition the

priority, and proposes to change the name used by all other describers. I doubt, how-

ever, whether this course could be justified, even by the law of priority. Chevrolat, in

1838, may be said to have characterized Amphionycha when he defined the genus Pyro-

bolus (giving Saperda fumigata, Germar, as the type) and stated that all the other species

belonged to Amphionycha. Saperda fumigata, however, is probably a true Amphionycha ;

and therefore Pyrobolus, established with positive characters, would be the prior name,

had it not been previously used in Botany, and apparently withdrawn subsequently by

its author. After this Leseleuc established the genus Amphionycha much more definitely

(in 1844); for, although in describing and figuring A. /uctuosa he did not give a generic

formula, he mentioned all the generic characters of the insect; and, in fact, no subse-

quent author, except Leconte, has been in doubt as to the genus, taking A. luctuosa as

its type.

The genus is distinguished from its allies by its linear form, vertical epipleure,

carinated on their summit, and filiform antenne, in which the third joint alone is

conspicuously elongated, and none of the joints thickened or furnished with dense

pencils of hair. Zeale was founded by its author on mistaken observation, the compact

tomentum in the species concealing the carine, which, however, really exist.

In Mexican examples the white fascia of the forehead is dilated above in the middle,

and extends in a point to the vertex. The white belts of the elytra vary in width and

form, but they remain only two in number. Mr. Champion met with examples in which

the white colour is partially or wholly changed to a beautiful rosy red.

obsolete beyond the middle of the elytra, and the punctuation of the surface is extremely

The lateral carina of the elytra is scarcely perceptible in well-preserved examples,

as without carina, and as therefore forming a separate genus. ‘The carina, however, is

This genus consists of a number of species of small size and dusky colouring, bearing

a striking resemblance to species of Glowworm of the genus Photinus. In some of

them the abdomen beneath has several segments clothed with whitish pubescence, in

imitation of the luminous organs of Lampyride; but this feature they possess in

common with a large number of American Phyteciini of widely different genera. The

elytral carinee in some of the species are not distinct ribs, but only the edges of the

angles formed by the vertical epipleuree with the dorsal surface; and they disappear in

some species, where the sides of the elytra are expanded. The males of some of the

species closely resemble in form the genus Alicia (Thoms.), in which the antenne are

clothed above and beneath in the same way with long soft hairs; but they have not the

almost completely divided eyes of that genus. One of the species was included in

Pannychis by Thomson.

ISOMERIDA.

Isomerida, Bates, Ann. & Mag. Nat. Hist. ser. 3, xvii. p. 373.

The chief character which distinguishes this genus from Amphionycha lies in the nature

of the hair fringe on the under surface of the antenne. Instead of forming a more or

less regular range of fine cilia, it is more or less condensed into tufts under each joint,

especially of the basal half. The third joint is never so long relatively as in Amphionycha

and allied genera, but is in nearly all species but little longer than the fourth. The

elytral carina forms a prominent rib.

About eight species are known, chiefly from Tropical South America.

to the scape, the remaining joints having the usual fine hairs. The elytral epipleure are

high; and the carina forms a distinct rib. About a dozen species are known, all

Very similar to H. longulus, but broader and more robust, with the sides of the elytra

flattened out (especially in the female) from before the middle, the explanated margin

increasing slightly in width until near the apex, where it is rounded off towards the

suture, the edge presenting a shallow sinuation before the sutural angle is reached.

Besides this difference in general form, there is a difference in the short black stripes of

the occiput, H. longulus having a distinct narrow vitta on each side separate from the

broad black stripe of the cheek, which vitta is wanting in all the numerous varieties of

H. varians. The punctuation of the interstices between the dorsal raised lines of the

elytra is irregular in H. varians, and arranged in lines in H. longulus. H. varians

appears to be a common insect in Guatemala, and has been sent home in great plenty by

Mr. Champion. I have adopted the MS. name given to it in the Sallé collection.

TYRINTHIA.

Tyrinthia, Bates, Ann. & Mag. Nat. Hist. ser. 3, xvii. p. 371 (1866).

Cyphometopus, Thomson, Physis, ii. p. 192 (1868).

The elytra in this genus are depressed, and more or less dilated towards the apex,

with epipleura, of small elevation, not separated from the dorsal surface by distinct

carine. The antenne have the third joint greatly elongated and, with the base only of

the fourth, slightly thickened and densely fringed with long hairs. The typical species

have in the male the forehead very prominent, and cleft in the middle by a longitudinal

furrow, giving it a bicuspid appearance as seen from above; but in some species this

striking peculiarity is much less developed, and in others the forehead is simply convex,

with a deep depression between the antenne. The same instability is seen in the similar

structure which distinguishes the genus Phebe.

' Eight species of Tyrinthia are known, nearly all from Brazil.

Spathoptera, Bates, Ann. & Mag. Nat. Hist. ser. 3, xvii. p. 8369 (nec Serville).

Nine species of this very remarkable genus are known, all, with the exception of the

one recorded below, South-American. The dilatation of the elytra and the imitation of

the genus ycus in form and colouring, which form so peculiar a feature in the group

of genera to which it belongs, here reach their maximum. The remarkable width of

the prosternum, a character foreign to the whole series of American Phyteciini, is shown

only in two of the species, L. simulatrix of the Amazons, and the following, L. belti.

It is not noticeable to any thing like the extent, as Lacordaire justly pointed out, in

L. togata. I have consequently been obliged to include in the genus two species from

the Amazons which resemble LZ. togata in this respect, and which I had referred to

Serville’s genus Spathoptera.

Notr.—During the progress of the above work a large amount of fresh material has

been received, contained chiefly in the rich private collection of M. Sallé (ceded to

Mr. Godman) and in successive arrivals from Mr. Champion and other collectors. As

will have been observed, many of the new genera and species thus obtained have been

incorporated since the commencement of the Lamiide ; the equally numerous novelties

in the earlier families, with rectifications of synonymy and additional notes on the

geographical distribution of the species, will form the subject of a Supplement.

SUPPLEMENT.

Tue very large accessions of new material received during the progress of the fore-

going work remain to be passed in review. It is in the two earlier families (Prionide

and Cerambycide) that the greater number of additions will be found, far exceeding

the original enumeration ; this is due chiefly to the circumstance that the great Mexican

collections of M. Sallé and Herr Hoge were not received until we had reached nearly

the end of the Cerambycide. The later labours of Mr. Champion, more especially in

the State of Panama, have also proved to be very productive in new species of Longi-

cornia. New information regarding distribution, corrections, and synonymical notes

relating to previously recorded genera and species, are also included.

Varies in size from 7 to 15 lines. The males show two tolerably well-defined grades

in the development of the mandibles; the fully developed, larger-sized individuals have

a very broad basal tooth, a sharp triangular median tooth, and a bifid apex; the less

developed and smaller individuals have no distinct basal tooth, the mandible being

simply broader at the base as far as the median tooth, which is much smaller than in

the larger form. Chiriqui specimens differ from the Mexican and Guatemalan form

in the obtuser, sometimes quite rounded, hind angles of the thorax ; but this character

is not constant, and examples occur in which the angles are prominent (7. e. preceded

by a short sinuation on the sides) on one side of the thorax and rounded on the other.

The Chiriqui form is also distinguished by the presence of a not very sharply incised

groove separating the forehead from the epistome or clypeus; this, too, is far from

being a constant difference.

A male specimen in the Sallé collection bears a label in M. Sallé’s handwriting

“ Psalidognathus mygaloides, Thoms..=P. wallisi, Taschenb.;” and M. Thomson

himself in his ‘‘Typi Cerambycidarum’ admits this probable identity. The description

of Taschenberg certainly fits the present species ; and Thomson’s P. batesi applies fairly

well to the larger individuals which seem to prevail in Chiriqui and in Costa Rica.

The only point on which I have some doubt is the carinated upper surface of the

4—11 antennal joints which Thomson attributes to his P. batesi, but which I fail to find

in the long series of examples examined. The carine, which limit the sensitive

cavities of the sides of the joints, and which become more and more dorsal as the .

cavities increase in size from joint to joint, become visible from above only with the

seventh joint; if the joints, however, were a little twisted, as they are liable to be in

badly preserved specimens, they might appear to be dorsal. None of the other

LONGICORNIA. 227

characters mentioned as distinguishing P. batesi from P. wallisi are valid. The man-

dibles of the male show grades of development nearly as they do in most male

Lucanide, and the spines of the thorax vary in a singularly abrupt way; though the

examples in which the anterior angles are rounded, or some of the lateral spines fail,

are rare. It is the same with the spines of the crown, so distinctive of this group of

Psalidognathus ; they are liable to become much reduced or disappear altogether.

Whether our species is really the P. modestus, Fries, or one of the very nearly allied

species found in the Cauca valley, must remain at present doubtful. But it is

extremely probable that these nearly allied forms are varieties of one and the same,

though they differ much in the female, the male offering no marked difference. The

singular flattened antenne of the male, which M. Thomson makes a distinguishing

feature of P. limbatus, is probably only an aberration, as antenne still more remarkably

flattened occur on an undoubted example of P. modestus taken by Mr. Champion on

the Volcan de Chiriqui. Under these circumstances, and considering that the present

species or race is the most widely distributed of the group, it will probably be found

that P. modestus, Fries, is the correct name for it.

species occurring in the British Islands. A species is recorded from Madagascar and

another from Australia; but temperate North America furnishes a greater variety and

five species belong to the genus. The two following are the first known to occur south

Resembles P. flohri; but certainly distinct, not only in the number of antennal

joints in both sexes and the shorter and broader joints of the male, but in the form of

the thorax in both sexes. In P. flohri the front edge is nearly straight, or describes

a single gentle curve from spine to spine; whilst in P. mexicanus (in both sexes) it is

trisinuate, the middle sinuation remarkably deep. The hind margin shows also a

striking difference, being strongly bisinuated in P. mexicanus, so that the middle part

forms a broad lobe; whilst in P. flohri it is nearly straight, but abruptly sinuate from —

the angle to the long and sharp basal spine. The head in P. mexicanus is remarkably

narrow, the eyes being not prominent, and the neck thick and broader than the part

across the eyes.

scabrous shoulders; the thorax rather closely rugulose-punctate and pubescent; the

antenne longer than the body, with the groove of the third joint extending only half

Hab. Mexico, Puente Nacional }, Orizaba (Sallé), Villa Alta! (Sturm coll.).

Differs from D. longicornis in the sides of the elytra being widely dilated from

behind the shoulders to the middle, their surface being more distinctly, but still

vaguely, furrowed and obtusely costate, and in the thorax being faintly rugulose

punctured, nearly smooth on the disc, and apparently not pubescent. The antenne

are similarly sculptured, the sulcus of the third joint extending about two thirds its

length ; but they are decidedly shorter, not quite reaching the tips of the elytra.

A female example has rather smoother and more polished elytra than the male.

The third antennal joint sulcated, in which it differs from D. longicornis (female).

Leconte’s description, “ Nigro-piceus, thorace ineequaliter varioloso-punctato .. . elytris

... basi punctatis humeris fere scabris,” applies rather better to D. inequalis, Bates,

than to the present species. A specimen, however, in the Sallé collection is named

D. sulcicollis, and there is no reason to doubt the correctness of M. Sallé’s deter-

mination.

Derobrachus inzequalis (p. 4).

To the locality given, add :—Mexico, Yucatan (Boucard), Cordova (Sallé), Misantla

The original description of this species given in Trans. Ent. Soc. 1872 (not 1869, as

quoted by error, supra p. 4), p. 167, was drawn up from what is now evident is a rare

aberration: a single male of brownish coloration, with the middle thoracic spine aborted.

In the large series received the colour is constantly sooty black, scarcely shining ; and

the thorax, short and broad as in D. sulcicornis, has on each side three very long and

sharp spines equally as in that species, the apical one of which is, in a minority of

individuals, subbifid. The thorax is much more coarsely punctured, and the elytra

more strongly furrowed and costate and more distinctly punctured near the base than

in D. sulcicornis. One female only has been received by Messrs. Godman and Salvin.

Hab. Muxico, Guachinango (Sallé). One example.

The apical lateral spine of the thorax, which in D. sulcicornis and D. inequalis is

sometimes subbifid (7. e. presents on its anterior side a short appendicular tooth), is here

developed into two nearly equal spines. Notwithstanding this character and the

granulate punctuation of the elytra, D. granulatus may probably prove, on the evidence

of further examples, only an extreme variety of D. inequalis; and the smoother thorax

points to the conclusion that all three (7. e. including D. sulcicornis) may be varieties

of one and the same very variable species.

Agrees with D. longicornis in the form of the elytra, which, however, are relatively

distinctly shorter ; in sculpture they differ from the allied species in wanting the

rough punctuation of the shoulders. The antenne are short, scarcely three fourths

the length of the elytra, and the fourth joint has a short sulcus. The thorax is nearly

smooth, and the lateral spines are rather shorter than in D. sulcicornis, the apical one

being in all three examples subbifid, 7.¢. bearing on its anterior side a short but

acute appendicular spine. The eyes are approximated above nearly as in D. longicornis.

One specimen with rather more elongate elytra has almost exactly the form and

appearance of a male example of D. geminatus in my collection from Arizona. Such

individuals may be readily distinguished from D. geminatus by the closer and stronger

striation of the antennal joints.

On my pointing out that the male of this singular species was a great desideratum,

Mr. Flohr made a special search for it, and at length succeeded in digging out from a

dead tree several examples with the apterous females. A single male, perfectly

similar to one sent me by Mr. Flohr, was taken also by Mr. Champion at Cerro Zunil.

It differs from all other species inter alia by the hairy legs and the absence of grooves

from the tibie, which are simply compressed.

The apical thoracic spine in the one example (Mexico) is bifid, in the other (Guate-

1 in. 5 lin. to 2 in. 10 lin.

5. Derobrachus (?) cylindroidus.

Hab. Guatemawa, Purula (Champion).

A single female specimen, of doubtful genus, but clearly allied to Derobrachus. It

is of similar elongate form to many Derobrachi, but rather more convex ; hence more

cylindrical, and the hinder margins of the elytra are thickened and rounded without the

usual sutural spine. The whole upper surface is coarsely and densely sculptured.

The eyes are distant above and narrow; the maxillary palpi greatly elongated, the

labial palpi unfortunately broken ; the thorax has only two lateral spines, but there is a

prominence in the place of the third (middle) spine. The terminal joints of the

antennee have on each side an elongate sensitive fovea, and only the eleventh joint is

striated above.

A further series of examples from intermediate localities seems to confirm the specific

distinctness of this form from C. senex ; but the chief distinguishing feature lies less in

the length of the mandibles of the fully developed males than in the presence of a

longish basal tooth on the inner side of each mandible in a large male C. barbatum, and

its absence in C. senex of the same development. The largest male in the series from

Guatemala has the tooth, though its mandibles are nearly as long as in the largest male

C. senex. A much larger and apparently more fully developed male from Chontales

STRONGYLASPIS (p. 6).

Strongylaspis scobinatus (p. 6).

Thomson, in the original description of this species, makes particular mention of the

spinose or (in one place) “subspinose” humeral angles of the elytra. As this feature

was not repeated in M. Chevrolat’s more careful subsequent description of the same

LONGICORNIA. 233

species from Cuba, I disregarded it in referring the Chontales specimens to 8. scobinatus,

in which there is no trace of humeral spine. A spine, or rather a small dentiform

prominence, formed by the prolongation of the humeral angle of epipleural fold, does,

however, exist in some examples, as I now find on examination of the additional material

arrived since the early parts of the present volume were published. The minute denti-

form process exists in a male example labelled “Guatemala” in the Sallé collection,

and in another taken in British Honduras by Blancaneaux. As, however, no other

difference of importance exists between these and Chontales examples, and the humeral

projection is much less prominent in one of the two examples examined, I hesitate to

consider them as separate species; the different forms of 8. scobinatus must at present

be classed as varieties as follows :—

S. scobinatus, forma typica. Elongato-subcylindricus, testaceo-rufus vel cinnamomeus, supra subtilissime et

parum dense cinereo-argenteo-pubescens ; elytrorum humeris tuberculo parvo armatis.

The following, from the different colour and greater density of its pubescence and

other minor characters, seems to merit specific rank :—

and thickness of the first antennal joint (“art. primus crassus obconicus”) and the very

thick mandibles surmounted at the base by a tubercle (“ mandib. crassissime, basi tuber-

culo obtuso elevato armato”); but it differs in the mandibles being much shorter than

the head, not “longitudine capitis,” and apparently also in the outline of the thorax.

well as by White and Lacordaire.

LONGICORNIA. 235

Crotch placed this species in the genus Nothopleurus. It approaches, in fact, this

genus very closely, the metathoracic episterna being slightly concave on their inner side ;

but the typical Wothopleurt have, in addition, the same parts very much narrowed,

whilst in the present species they are but little narrower than in the genus Mallodon.

The species, in fact, bridges over the difference between the two genera which Leconte

(Class. Col. N. Am. 1873, part ii. p. 287), not knowing the typical species of Notho-

pleurus, declined to separate. NV. mandibulare has, however, a further peculiarity in

common with Nothopleurus, and which distinguishes the genus from Mallodon; this is

the form of the hind angles of the thorax and the adjacent lateral margins; the margin

is here obliquely sinuate, with a long spine anterior to and a shorter spine posterior (at

the angle itself). Stenodontes in both sexes presents the same constant peculiarity of

structure.

The narrow metathoracic episterna, with long incurved inner margins, show that this

species belongs to the genus Nothopleurus; in the form and sculpture of the thorax it

is very similar to Stenodontes exsertus (Oliv.), and the mandibles resemble those of

Stenodontes. The prolongation of the lower margins of the cheeks, which go far to

enclose the sunken throat and mentum, as in a box, are but an extreme development of

what is seen in Mallodon maxillosum (F.).

This interesting and most beautiful species bridges over the slight difference between

the genera Mallaspis and Pyrodes. It resembles P. marginatus in colour, but differs

both from that species and from P. tenuicornis in its very much finer sculpture,

smoother surface, densely pubescent scutellum (at least in the male), and in its shorter,

smoother, and otherwise coloured antenne. From the male of Pyrodes marginatus it

is further distinguished by the short, ovate, terminal joints of the antenne, the three

apical joints in P. marginatus being linear and having (like MZ. moreleti and M. lampros)

an acute tubercle at their base. Five males and one female.

Mallaspis rhombodera (p. 10).

Mr. Champion reports that the apical half of the antenne in this species is quite

pale in the living insect.

Mallaspis precellens (p. 11).

Mr. Champion took this species in great abundance in the forest region of Chiriqui,

at altitudes of from 800 to 4000 feet. The thorax resembles that of AZ. rhombodera in

the lateral explanated and serrated margin not commencing until some distance from the

anterior angle; it is, however, narrower, and further differs from that species in having a

very prominent and acute tooth just before the posterior angle. It varies in size from 10

varies from coppery to brassy-green, and in rare cases rich metallic blue.

This species would not have merited distinct mention as more than a geographical

variety of the IZ. paradoxa from Chontales, if it had not presented a structural peculiarity

of great systematic importance. Whilst 1. paradoxa has no trace of the raised thoracic

lateral margin which is one of the few distinctions of the Prionine as a subfamily, this

evidently geographical variety of the same immediate stock has the margin distinctly

indicated, and, further, denticulated, as is usual in Mallaspis. As evidence of its

varietal condition, it is more or less developed in the different individuals. In sculpture

and colour there is no difference between the two forms, except that in I. insignis the

antenne and legs are dull bronze-brown or castaneous, and present very little of the

rich violet lustre of the same organs in I. paradoxa.

Does not essentially differ from H. levithorax either in form or colour. It is,

however, very much smaller and narrower; the antennz are longer and slender; and

the thorax, especially in the female, much more strongly narrowed in front. The

interruption in the septum which (in H. levithorax) divides the opaque patch on the

sides of the thorax into two areas is probably only accidental.

broader or longer, more or less rounded on the sides and narrowed in front; the

sculpture and prominence of the raised dorsal line also varies. In size the species

ranges from 6 to 15 lines.

Guérin’s description fits the present species rather than a nearly allied one found

also in Colombia and having similarly striped elytra, the words “‘ extrémité des articles

Carolina, with which I have compared them; they are not simply acute, but are pro-

longed into distinct spines. But, besides this variety, the following form also occurs in

Mexico and has the appearance of a distinct species :—

Eburia stigmatica (p. 19).

Eburia perforata, Leconte (p. 19).

The only ground on which Leconte separated his species from E. stigmatica, as he

himself states, was the presence of a spine at the sutural as well as at the exterior angle

of the elytral truncature, Chevrolat expressly describing the elytra as having only an

- exterior spine at the apex and being “ tronquées sur la suture.” The examination of a

numerous series of E. stigmatica from Mexico, named as such in the Sallé and other

collections, proves, however, that Chevrolat made a mistake in his description or had

a mutilated specimen before him; all have a distinct and long spine at the sutural

angle. There remains therefore nothing to separate the two species. By the rules of

priority, as at present understood, I presume the older name of the species must be

retained in spite of the false description.

the insect a different appearance.

This species has quite lost the appearance of an Eburia, owing to the denuded black

the elytra are in the situation of the rudimentary nervures seen in several other species,

and the two separated linear median ivory spots are situated upon them. ‘The callus.

on the site of the thoracic spine is scarcely elevated in the female and wanting in the

male. I obtained a male specimen of this species without locality at the sale of the

shows them distinctly on the third and fourth joints; but the furrows are not deep or

carinated on the margins as in the deceptively similar £. callixantha and in all the

of the thorax and the width of the smooth longitudinal vitta, but the differences are

not constant, and with the material before me it is impossible to do other than consider

all as belonging to one and the same species. The male, as in H. truncatus, to

which H. inermis is most nearly allied, has a quite different thoracic sculpture, close

and fine, with rather larger punctures intermixed.

condensed into patches, which cover nearly the whole elytra, browner specks being

interspersed, and a longer brown spot being conspicuous on the sides, a little behind

the middle. The thorax is more oval, and the centra] polished space in both sexes

does not extend to the front edge, but forms a short line only near the middle.

In many respects, and particularly in the form of the head, Cacophrissus seems to be

allied to Anoplium, Haldemann, but in that genus (incorporated by Leconte with

Elaphidion) the thorax has the sexual difference of sculpture characteristic of the

Elaphidion group. Cacophrissus has much in common also with Perilasius, but it

differs in the short subequal palpi (Perilasius having much elongated maxillary palpi),

in the grooved antenne, &c. The antenne are compressed and slightly dilated, not

sideways, but above and beneath, and the middle of the broadened upper surface is

faintly carinated or roof-shaped, this being more visible in the male than in the female,

and on the third to the sixth joints.

or less confluent, spread over the surface, but chiefly in an ill-defined streak on the

sides, and another shorter and oblique on the disc towards the base.

PERIBCEUM (p. 27).

Stizocera, Serville, Ann. Soc. Ent. Fr. 1834, p. 107 ?

Stizocera, Serville, according to that author’s definition, is very near Peribeum,

Thomson, differing chiefly in the third to the fifth antennal joints only being spined ;

the oblong-ovate unarmed, smooth, but somewhat uneven and depressed thorax

being a less important character, and the bidentate apex of the posterior femora existing

in greater or less development in most species of Peribeum. None of the authors who

have since dealt with the Spherionine appears to have been acquainted with the type

of Serville’s genus S. armata, from Brazil. It seems, from the description, to be

identical with my Nephalius fragilis (Trans. Ent. Soc. 1870, p. 274), though the size

of the two insects is widely different, V. fragilis being 5% lin. and S. armata 10 lin.

Being unacquainted with most of the described species of the group, I do not feel

justified in substituting the name Stizocera for Peribeum, though it is highly probable

the respective type species represent two distinct genera. The number of spined joints

in the antenne, in short, may be a generic character: Serville gives for Stizocera 3-6,

overlooking, I think, a minute spine at the apex of the sixth, whilst in the type of

Peribeum (P. acuminatum, Thoms.), joints 3-8 have long spines.

Allied to P. dbimaculatum, and forming with that, and probably other species, a group

latum, however, we have an approach to the thoracic sculpture of the typical Peribwa

in the smooth dorsal space or callus, besides the more abruptly clavate femora.

NEPHALIUS (p. 27).

This generic name is inapplicable for our Central-American species and must

be withdrawn; they should be all referred, at least provisionally, to Peribeum.

Lacordaire’s suppression of Newman’s genus Nephalius, and its reconstitution under

the same name for the reception of a different series of species, is a proceeding which

is not likely to meet with permanent approval; and it is better at once to restore the

name for the group which embraces Newman’s typical (or first) species, viz. WV. amictus,

which has since received a new name, viz. Mephritus, Pascoe. Nephalius amictus,

Newman, is nearly allied to, if not identical with, Pascoe’s type (Mephritus cinerascens).

The true Mephalii, as far as at present known, are from South Brazil, at any rate

none are contained in our collections from Central America.

Notwithstanding the extraordinary bell- or cymbal-shaped development of the apical

P. castanea that it cannot well be removed from the genus Psyrassa.

This would be a Mallocera, Sect. 2, according to Lacordaire’s definition; but it is

clearly more closely allied to Eurysthea obliqua than to the type of Mallocera. It

differs from Eurysthea in the spined antenne and the less clavate hind femora. Further

material is required to test the generic validity of these characters. I suspect they are

variable, having before me an allied species in which some examples have only the

third joint spined, and others both the third and fourth.

examined a large number of species, I am inclined to agree with him; the greater

length of the spine at the tip of the intermediate femora which distinguishes a few

extreme forms, and is the sole character of Hexoplon, not being supported by other

structural modifications. One of the chief features which distinguishes Gnomidolon

and Hexoplon from Ibidion and Octoplon appears, however, to have been overlooked by

Lacordaire, though duly mentioned by Thomson; it is the long and slender curved

scape, almost always produced or dentate at its exterior apex. The form of the

antenniferous tubercles, which Lacordaire brings into the first rank of characters,

appears to have no systematic importance.

About a dozen species of the group Hexoplon are known, and more than a score of

in their narrow prosternum sunk beneath the much exserted fore coxe, the genus

Eligmoderma. TI. latevittatum has a similar thorax (roughly sculptured with five

dorsal tubercles) to I. integripenne ; the elytra also are relatively greatly elongated and

entire at the apex, but the pale markings are widely different, the whole disc being

occupied by an elongated ochreous stripe of broad but not quite regular width, leaving

only the sutural, lateral, and apical margins (which around the apical part are very

narrow) of the brassy chestnut-brown ground-colour.

Labelled J. tenellum, Dej., in the Sallé collection, a name adopted for another

San Feliz, San Lorenzo (Champion).

The long series of specimens I have been able to examine show this species to be

extremely variable, not only in colour (from ashy brown to light tawny red), in

shape of the elytral spots, and in pubescence (sometimes nearly glabrous and at others

clothed with very fine sericeous tomentum), but also in the form of the apex of the

elytra, which Thomson emphasizes in his diagnosis, to distinguish the species from his

L. mexicanum, as “ obliquely truncated, with the outer angle acuminate.” ‘The apex

varies:—1. Transversely sinuate-truncate; sutural angle prominent, acute; exterior

angle elongate-spinose. 2. Obliquely sinuate-truncate; sutural angle obtuse, exterior

dentiform. 3. Obliquely and obtusely truncate. These modifications of elytral trun-

cature, pubescence, and colour all occur together at Chontales and Jalapa; but I do

not find obtusely truncated specimens in the series from the State of Panama. In size

the species varies from 74 to 16 millim. The fourth antennal joint is remarkably short,

the third to the sixth broadened and flattened with a central carina. The prosternum

and fore coxe are nearly as in Heterachthes and the majority of species of Ldcdion.

The hind tibie have a rudimentary carina on their outer side at the base only.

Numerous examples of this form were taken by Mr. Champion, all distinguishable

from J. textile by the elytra being gradually dilated from a little before the middle to

near the apex, whence they are more rapidly narrowed again, the apex itself having on

each side a rather long and sharp slightly incurved spine, and the sutural angle being

acute. In the dark brown examples the elytral spots are indistinct, and the insect

resembles certain specimens of J. textile of the same colour from Coatepeque; but in

the light tawny-yellow examples the spots are conspicuous, the hinder one not trans-

verse and smaller than the anterior one.

the two slender subbasal fascie of the elytra being nearly parallel and oblique rear-

wards from the base to the suture; the posterior discoidal patch is, however, much

shorter and divided into two short subparallel vitte, and the subapical fascia, instead of

being near the apex and straight or slightly oblique, is further removed from the apex

from the allied species in the form and position of the posterior fuscous markings of

the elytra, which here consist of two slender fascie curved in such manner that the two

together form on the elytra a common large transverse-oval ring. The original de-

scription was drawn up from a single specimen, evidently immature or defective in

colouring, the antenne and thorax being spotless or nearly so, and the basal markings

of the elytra indistinct; the antennal joints in well-developed individuals, of which

Mr. Champion took a good series, are tipped with fuscous, the thorax has two fuscous

vittee, and the base of the elytra a broad fascia, from the hinder edge of which proceeds

on each elytron an oblique streak extending to the suture, of the same chestnut-brown

colour. ‘The hind femora and tibie are also more or less streaked with fuscous. |

captured this and many other species of the genus by beating the withered leaves of

fallen or felled trees in fresh clearings in the forests; the Distenie, as well as many

other Longicornia, are fond of hiding in the curled-up leaves in the daytime, and

probably sally forth only at night.

Very similar in form and colours to the C. acutipennis, Buq., of Cayenne, but differing

in the form of the head and the punctuation of the abdomen. In C. acutipennis ( ¢ )

the head is narrowed immediately behind the eyes, which latter are prominent, and the

abdomen is very closely and coarsely punctured. If the two examples of C. hilaris are,

as I believe, males, they offer further a great difference from the same sex of C. acuti-

penms in the terminal ventral segment, which in C. acutipennis is greatly elongated,

semitubular, and broadly truncated at the apex*.

* T profit by this occasion to correct an error in the remarks on C. acutipennis and on the genus Heteropalpus,

which I published in Trans. Ent. Soc. 1870, p.441. I there say that the ¢ of C. acutipennis has the singular

form of maxillary palpi which characterizes the genus Heteropalpus, the 9 having normal palpi, and that this

genus is therefore untenable. The pair of C. acutipenmis received from Paris, labelled as such, on which the

above remark was founded, I now find to be both males, and, notwithstanding the identity of colours, to

belong, the one (the true C. acutipennis, Buq.) to Cometes, the other to Heteropalpus.

GUATEMALA, Quiche Mountains 7000 to 9000 feet (Champion).

The species is of abnormal appearance therefore only in the female, and even in that

sex the elytra are sometimes no longer relatively than in many other species of the

genus. A more important character, and one which distinguishes this and the following

species (L. anomaia) from all other Lepture, is the short and broad vertical forehead.

The colour varies from dull black to castaneous, and the abdomen is sometimes

testaceous red (var. erythrogaster, Sturm, MS.): the latter peculiarity exists in examples

which do not differ in other respects, and is in no wise specific. The sculpture of the

head and thorax consists of round punctures, which are sometimes smaller and sometimes

larger, in the latter case being close together and subalveolated, leaving a smooth

dorsal line.

The mesosternum in this species, and in O. rostrata from Colombia, is very convex;

this character, joined to the form of the thorax and the angular shoulder of the elytra,

is perhaps sufficient to warrant the generic separation of the two species from Ophistomis.

280 SUPPLEMENT.

Two examples; both these have the apical ventral segments simply concave near the

apex, without trace of raised margins. The Guatemala specimen has, however, the more

slender form of the male sex; and, if it be really a male, the species must be specifically

distinct from 0. rufiventris, in which the same segment has a long triangular excavation

with raised margins. So abrupt a structural modification would be very remarkable,

the excavated last ventral segment with raised margins having been considered a generic

character; such abrupt changes are common in the Longicornia, and the closely allied

The four marginal black spots of the elytra are, in the male, placed thus :—one below

the shoulder, small, and sometimes wanting ; one near the middle, triangular, not reaching

the suture; one behind the middle, reaching the suture; and one occupying the apex and

often nearly blended with preceding. In the female the four spots are detached and

(the apical one excepted) rounded.

mode of flight, almost like that of a gnat. He took a very large number of specimens,

nearly all of which prove to be males. The female resembles, in the markings of the

thorax and elytra, the same sex of O. beléi; but in other respects it is widely different,

being much smaller and having much shorter antenne, the fifth joint of which is some-

what shortened and thickened towards the apex, whereas the same joint in 0. belti is as

A genus formed for the reception of certain species which are intermediate in their

characters between Ophistomis and Euryptera, and cannot be included in either without

rendering their definition impossible. In most of their characters they agree with the

genus Chontalia, which has similar antenne, the third and fourth joints being linear

and not shorter than the remainder taken singly; but in Chontalia the anterior coxe

are much less exserted, the muzzle longer, and the general form and facies different.

The body is clothed with rather longer and more erect hairs both on the thorax and

elytra than in LZ. lateralis; the punctuation of the elytra is a little coarser and sparser,

and has a rough appearance owing to the edges of the punctures being raised. It

is doubtful if the male above described really belongs to this species: the difference of

colour of the thorax might not be important, but it differs in outline; the other

characters are the same, especially the important one of the relative slenderness of the

antenne ; the elytra, though with similar peculiar punctuation, differ in their truncature,

which is less obtuse and has a minute projection at its external angle.

and resembling an Odontocera rather than an Acyphoderes; but the elevated central

callus of the thorax, the much-narrowed elytra, the strongly tumid club of the middle

femora, and the form of the antennal joints, show that it belongs to the latter genus.

green, and there are two narrow dusky stripes on each elytron, which are the remains

of the broad velvety-black vitte (one discoidal, the other marginal) of C. aureotincta.

The sculpture of the thorax, finely alutaceous on the disc and transversely striate on

the sides, and the well-developed lateral spine, the scarcely produced exterior apex of the

scape, and the red femora are the same as in the type-form. The only difference is the

Common on felled or fallen timber in the more open parts of the forest-region of the

“tierra caliente” of Chiriqui (Champion).

The three preceding species are almost exactly alike in colours and markings, and are

with difficulty distinguished. Of the characters mentioned by Chevrolat the chief are

the number of the narrow yellow belts of the thorax, which are four in C. crinicornis,

and three in C. erythropus and C. guttata ; the two last named are distinguished from

each other by general form, C. erythropus being relatively much broader, especially

at the base of the elytra. I find the shape of the yellow spot on the pygidium to be a

good differentiating character; it is a narrow line in C. erythropus, and a large oval spot

in C. guttata.

The differences may be more readily seen in the following table :—

Thorax fasciis flavis tribus.

Hab. Panama, Bugaba (Champion).

Belongs to the subgroup which embraces C. acuta, C. cayennensis, C. caracasensis,

and C. amazonica, which might almost be considered as so many local varieties of one and

the same species. The colour is silky black, with three thoracic and four elytral fasciz

(besides a short streak along the suture at the apex) ashy yellow; the second and third

elytral fasciee are curved forward towards the suture, and are prolonged a little on the

latter towards the base, and the fourth fascia is broken into a spot on the suture, and

an oblique line across the disc. The reddish colour of the legs and the antenne alone

-would scarcely suffice to distinguish the present form as a variety, but the character is sup-

ported by the ventral segments having three large yellow spots on each side, instead of two.

usually away from the vicinity of the forest.

Ochresthes obliquus (p. 51). (Tab. XXI. fig. 2.)

To the locality given, add:—Mexico, Jalapa, Las Vigas (Hoge).

Distinguished from the allied species by the narrow, nearly straight, dusky belt near

the base of the elytra, extending, as Chevrolat expresses it (but only in well-developed

individuals), from one humeral callus to the other. I have seen no specimen in which

this fascia is wanting, as Chevrolat says it is in the female; but a dark variety occurs in

which the five dusky oblique fascie are more or less blended together (the dark colour

being thus diffused over the whole elytra, leaving only a narrow basal margin), and

there is an oblique spot before the middle on each side, and a rounded spot on the

suture towards the apex, of the ochreous ground-colour.

Ochresthes sommeri (p. 51).

To the Mexican locality given, add :—Guanajuato, Puebla (Sad/é).

I suspect 0. circuliferus, Chevy. (p. 51), to be nothing more than a colour-variety of

this species; the descriptions of both are the same with regard to the annular shape of

the twin black fascia near the base, which is shown in all the numerous examples of

O. sommeri, and is highly characteristic.

LONGICORNIA. 297

Ochresthes citrinus (p. 51).

According to examples (one of which is from Puebla), no doubt authentically named,

in the Sallé collection this species resembles O. sommeri in the elytral markings, which

consist of two twin dusky fascie enclosing spaces of a lighter ochreous than the ground-

colour, one pair a considerable distance from the base (the basal space being quite free

from dusky lines), the other pair at a similar distance from the apex; the difference

between the two species is that the basal fascie in 0. citrinus reach from the margin

nearly to the suture, and are sharply triflexuous, in O. sommeri they form a transversely

oval dusky ring enclosing a rounded ochreous spot. ‘There is, however, an important

structural difference relatively between the two species—the elytra in O. citrinus being

much longer and obliquely sinuate-truncate, with acutely produced external angles ;.

in O. sommeri they are broadly and transversely truncated.

Specimens labelled O. z-littera in the Sallé collection do not differ in the slightest

from O. citrinus, but they do not agree with Chevrolat’s description.

Fully-coloured examples may be distinguished from all other species of the O. pol-

from shoulder to shoulder with many undulations. But most of the examples sent

have indistinct or partly obsolete elytral and thoracic markings ; these are distinguish-

able from similar specimens of the equally robust O. sommert only by the broader and

almost spherical thorax, by the antenne in the female much thickened towards the

apex, and the relatively longer elytra. 0. pollinosusis always much narrower, and with

elytra tapering near the apex, the apex itself obliquely and sharply truncated.

The type specimen, unique, was found, according to its describer, Chevrolat, in the

neighbourhood of the city of Mexico. It is singular that the only example I have

seen which comes pretty close to Chevrolat’s figure is one from British Honduras.

A Mexican specimen from Almolonga differs in the apical portion of the elytra, except

its margins, being black. The Chontales form is a tolerably distinct variety, which

may be named WV. ionides.

In the shortness of the forehead and the markings of the elytra this species resembles

the Neoclyti more than the Mecometopi, but the nearly smooth, convex thorax, and

especially the short clavate antenne, in which the joints seven to eleven are consolidated

into one with only faint traces of articulation, lead me to refer it to Mecometopus, in

‘which genus alone a similar antennal structure is found.

Neoclytus(?) distortus (p. 58).

There is an example (25 millim. long) of this magnificent species in the Sallé

collection with the locality “‘Mexico” attached. The species can scarcely remain in

the genus Neoclytus, as the thorax, instead of having a central longitudinal crest, is

broadly flattened on the disc and its sides are strongly rounded. The hind thighs also

are not clavate, though elongated (extending beyond the apex of the body) and biden-

tated at the tip. The prosternum is very narrow between the coxe. In most of these

characters the following species agrees with it.

Resembles Cyrtophorus, especially C. hieroglyphicus and C. verrucosus, in facies and

some of its characters, but belongs to the Tillomorphine group in its sternal structure,

the intermediate haunch-sockets being closed by the prolongation of the side processes

of the mesosternum. The eyes in some of the species are perfectly round and distant

from the base of the antenne, and in others have a slight sinuation on their inner

edges ; in the allied genera, Tillomorpha and Euderces, at least in the typical species,

they are reniform, with the upper lobe more or less attenuated. In some species the

third and fourth antennal joints have a very small rudimentary apical spine, but

others are without traces of it. The elytra, as in Cyrtophorus, have a steep rounded

posterior declivity ; they have towards the base an oblique elevation, which is followed,

in the typical species, by a smooth depression, and the apex is rounded. The antenne

are nearly as long as the body, filiform.

1. Tilloclytus balteatus.

Tillomorpha balieata (p. 59).

The type specimen is ticketed “‘ Cordova” (Sallé). T. balteatus differs from the other

two species in wanting the smooth oblique line immediately behind the basal crest of

the elytra.

Tillomorpha hematocephala (p. 59).

To the locality given, add:—Muexico, Orizaba (Sallé), Oaxaca (Hegewitsch in coll.

In the type, from Orizaba, the middle part of the elytra (extending towards the base)

is blackish brown, on which is a pale belt (along the depressed line behind the basal

elevation), and a pale triangular spot on the suture; in the Oaxaca specimen the

central part is tawny red, the margins of the pale belt and the apical cinereous spot

only being dusky.

LONGICORNIA. 309

Of described genera of Cerambycide this genus comes nearest to Lissozodes; but it

is also closely allied to Ozodes and to Sthelenus, which last is placed by Lacordaire in

the neighbourhood of the Molorchides, a widely different group. In Lissozodes the

anterior haunches are salient, but not to the extent reached in Eucharassus. The

antennee in all the genera, and in others still undescribed belonging to the same group,

are similar in length and form, and in the proportions of the joints; but Hucharassus is

distinguished for the remarkable clean-cut groove from the base to the apex of the third

joint and the double groove (one on each of the compressed sides) of the fourth and

following joints. The antenne and legs are not clothed with long and abundant hairs,

In the great majority of the specimens the thorax is red beneath; this is not there-

fore a distinctive character of R. rubecula; the latter differs from F. cupricollis more

constantly in having a rather broad black dorsal vitta on the thorax. In K. cupricollts

the surface of the thorax varies in being spotless, having a central dusky spot, a short

dark line, or a continuous narrow dorsal line. The last mentioned approaches extremely

near R. rubecula.

The specimen in the Sallé collection is a variety in which the underside of the pro-

thorax is black clothed with ashy pile, and the anterior and posterior margins above

are also rather broadly black. All the other examples are red above and beneath, and

marked with longitudinal grey streaks. In the female, in this and the allied species, —

the thorax is shorter and relatively broader than in the male. |

Rhopalophora tenuis (p. 62).

This species is doubtful. It was described from what appeared to be a single

example in Count Mniszech’s collection. It is possibly only the female of £. miniato-

collis, in which the grey pubescent lines of the thorax are abraded. A specimen nearly

agreeing with the description is among the Oaxaca series of . miniatocollis taken by

Herr Hoge. In the Sallé collection specimens of the following are labelled &. tenuis,

Var. Agallissus quadrimaculatus (p. 68).

In the Sallé collection is a male example of this species (named A. guadrimaculatus,

White), intermediate in the elytral markings between the var. trifasciatus and the true

A, quadrimaculatus, White. It differs from the latter only in having a red apical spot

as in the var. trzfasciatus, from which it differs, on the other hand, in the median and

subapical fasciee not reaching the suture, the median especially being far distant; the

antenne are a little longer than in the female, reaching to beyond the middle of the

elytra; the latter are rather more narrowed behind than in the female.

Pteroplatus, Thomson, Leconte.

Elytroleptus, Dugés, La Naturaleza, iv. p. 184.

Distinguished from Pteroplatus, which the species much resemble, by their short

antenne (in the female of the typical species only about one third, in the male more

than one half, the length of the body), and by their joints 5-11 being triangular and

produced at their inner apices, none of them being penicillated, even in the male. The

species described by Dugés are more linear in form than the Pteroplati; but this is

not a constant difference, other species having dilated elytra, and the facies of Lycus

similar to the Pteroplati. The genus seems to be peculiar to Mexico and the southern

United States; Pteroplatus floridanus, Leconte, belongs to it.

1. Elytroleptus octocostatus (Pteroplatus octocostatus, p. 73).

This species has serrated antenne, with the four basal joints clothed only with short

hairs; it belongs, therefore, to Elytroleptus rather than to Pteroplatus, but it is peculiar

in the strong dilatation and fringed margins of the elytra and in the form of the

thorax.

CRIOPROSOPUS (p. 74).

The remark in the former part of this work that C. rimosus differs in essential points

from its congeners was founded on the supposition that the great sexual difference it

displays in the sculpture of the thorax (densely punctured in the male, sparsely so in

the female) was peculiar to it. The subsequent arrival of more abundant material

proves that all the typical species of the genus present this sexual character. The type

(C. servillei) must therefore be a female, the other sex of which remains to be discovered,

and the metallic species from Guatemala, which I took to be a female of C. iridescens,

the male of a distinct species.

The genus, as at present constituted, contains two distinct groups, meriting generic

rank, as they differ from each other nearly as much as Stenaspis differs from Criopros-

opus. ‘The typical or first group is characterized as I have above stated; the second

group, typified by C. viridipennis, is distinguished by the thorax of the male having

the sculpture confined to a limited area towards each anterior angle, the thorax in the

female being quite smooth. To this group ,belong C. viridipennis, C. lampros,

C. rutilans, and C. cacicus*,

Hab. Mexico, Toxpam (Sallé).

One example in the Sallé collection, labelled ‘‘ Stenaspis divisus, Chevr.” I think

it very likely to be the male of Crioprosopus nietoi.

The sides of the thorax are very slightly angulated, a little behind the middle.

Crioprosopus iridescens (p. 74).

The unique male of C. iridescens, White, from Guatemala, which I examined at the

British Museum, and which has since been carefully compared with specimens of

C. championt and C. basileus by Mr. Champion, appears to belong to a species distinct

from both. The thorax is relatively much broader, the lateral tubercle broader and

more obtuse, and the antenne much longer than in C. basileus. The fulvous trans-

lucence of the brilliantly metallic green elytra mentioned by White appears attributable

to immaturity. The mesosternum is nearly plane.

3 (a). Crioprosopus championi (Crioprosopus iridescens, ° , p. 74, nec White).

The two specimens from Zapote referred as female to White’s species prove to be

of the same sex(¢) as White’s typical example. They are nearly the same in colours

as C. iridescens ( 3) and C. basileus( 3); but C. championi ( 3) differs from both in the

transversely ovate form of the thorax, the sides of which are strongly arcuated, without

trace of lateral tubercle or conical protuberance. The antenne are also much shorter,

one fourth shorter than the body ; the length is 18 lines.

Crioprosopus basileus (p. 75).

d. Described on p. 74 erroneously as 9. The antenne are of the length of the body.

Herr Hoge took a series of both sexes of this species (including one example of

LONGICORNIA. 321

C. thoracicus, which has been compared with White’s type) near Merida. The males

do not differ from the Oaxaca specimen described (as above cited) at p. 75, except that

the mesosternum has a more distinct conical tubercle.

Crioprosopus tricolor (p. 75).

Mr. Champion has examined the type of Waterhouse’s species in the British Museum,

which proves to be a female, closely resembling C. basileus, 2, above described, but

differing in the much shorter scutellum. The sculpture of the thorax also is different,

the disc being punctured equally with the sides (in C. basileus, 9, the disc is smooth),

and the surface having shallow scattered impressions. The mesosternum has a distinct

conical tubercle, but the antenne are more slender and shorter.

Probably the female of a species distinct from any of the foregoing. Its locality is

supposed to be Venezuela, and it must therefore be erased from our list.

Stenaspis verticalis (p. 76).

To the localities given, add:—Mexico, Izucar (Sallé), Ventanas (Forrer), Bobo

Differs in the degree of closeness of its punctuation and in the colour of the scape,

according to locality. Sonora and Ventanas examples have large smooth spaces on the

thorax in both sexes, and the scape red, except at the tip. All the Bobo.examples

are distinguished by the very close confluent or vermiculate punctuation of the elytra,

and the rather less dense sculpture of the thorax, and the scape is always black.

Captured in great abundance by Herr Hoge at Bobo.

822 SUPPLEMENT,

A still greater local variation in sculpture is presented by this species. Ventanas

specimens are rendered subopaque by the close and fine vermiculate punctuation of the

elytra, the thorax being much more coarsely but also densely punctured. Alamos

examples have a nearly smooth thorax.

To the locality Mexico, add :—Almolonga (Hége), Alamos (Buchan-Hepburn).

8. Antennis quam corpus fere duplo longioribus, articulis 3°-4" haud sulcatis.

The thorax is in most examples rounded on the sides, without trace of lateral

tubercle, in others it has a lateral tubercle, as described ; it is bright blood-red in colour,

with the anterior and posterior margins black. The apex of the elytra varies also in

a singular manner, being either obtusely rounded or flexuous-truncate, with the ex-

terior angle dentiform.

As mentioned in the description, the surface is slightly shining, and the elytra bluish

black. ‘The punctuation is fine on the elytra, but each puncture is separate from its

neighbour; on the thorax the punctures are larger, deep, and circular, and mostly

widely spaced.

The species has a close general resemblance to Batyle ignicollis, Say, but is well

distinguished by its generic characters, the mandibles in Batyle being acute and simple

at the apex, and the hind femora and tarsi elongated. It agrees very well with

Thomson’s description of Muscidora tricolor except in the important character “ frons

lateraliter subarmata;” there being no trace of any prominence on the forehead in any

of our numerous examples of D. nigripennis, I am obliged to infer that Thomson’s

insect is a species belonging to some genus of this numerous group unknown to me.

Long. 5-8 lin. $2.

Hab. Mexico, Izucar (Sallé), Ventanas (forrer).

In form and colours similar to D. nigripennis, and the thorax varying in the same

way with regard to the lateral tubercles being present or not, even in the same sex ;

but the surface is opaque, owing to the close sculpture which is formed, on the thorax,

of shallow round fovee, and, on the elytra, of minute confluent punctures. The

elytra are dull black, with the exception of a red lateral vitta extending from the

shoulders. to a little beyond the middle, and there tapering to a point. The apex of

the elytra also varies nearly in the same way. Some of the Ventanas specimens are

intermediate in respect of the punctuation of the elytra between the two species; the

two forms approach therefore very nearly the status of geographical varieties.

- This species is the analogue of Batyle meridionalis (resembling it in colours and to

some degree in sculpture), as D. nigripennis is that of Batyle ignicollis.

Notwithstanding its bright red colour and style of markings, more nearly allied to

Deitaspis than to the similarly-coloured Ty/osis. In well-developed males the third and

fourth antennal joints show distinct traces of a groove, as in D. auromarginata and

D. rubriventris. The species would fit almost equally well in the genus Crossidius, with

which Deltaspis is very closely allied.

differs, in fact, but little from Zragidion: the antenniferous tubercles are short, as in

T. carinatum, but the hind femora are longer and more slender; the densely hairy

hind tibiee it possesses in common with T. annulatum and T. carinatum.

Allied to Zragidion by its structural characters, the chief exception being that the

LONGICORNIA. 325

forehead is not separated from the lateral space near the eye by a continuous raised

line, but there are traces of a sharp limitation. In general form and sculpture, however,

the genus bears no resemblance to T'ragidion, the form being convex and nearly cylin-

drical, with the surface densely and finely sculptured, without coste or other inequali-

ties. The antenne resemble those of Zragidion annulatum, but the joints are more

densely hairy at their apices.

TYLOSIS (p. 81).

Tylosis maculata (p. 81).

Having had an opportunity of examining a typical specimen of this species, named by

Leconte, in the Sallé collection, I find it is distinct from the Mexican species, which I

describe below as T. puncticollis. It is broader in form, with a broad subspherical

thorax. No Mexican specimen agreeing with it in form or markings, the species must

be withdrawn, as not belonging to our fauna.

The sutural vitta is very variable in extent; in its fullest development it reaches the

base, and is of the width of one third the elytron, and at its feeblest it is reduced to a

narrow line along the middle portion of the suture; in some examples it is entirely

wanting, and unless more than two spots are then present on the thorax, the species

would with difficulty be distinguished from T. oculata.

Hab. Mexico, Guanajuato, Silao, Leon! (Dugés), Lerdo (Flohr), Saltillo in Coahuila

A large species (reaching in some examples a length of nearly 10 lines), distinguished

by its broad, strongly rounded thorax, the middle of the sides of which is sometimes

angulated, or even forms a short conical tubercle. The punctuation of the elytra is very

coarse near the base, and minute and confluent towards the apex. ‘The elytra are more

variegated with black than in 7. puncticollis, the spots being variable: but in all the

varieties the species may be distinguished by the apex of the elytra being of the red

ground-colour, and the subscutellar and humeral spots elongated.

Closely resembling Zylosis in colours and markings as well as in structure, but

LONGICORNIA. 827

differing in the thorax having in the middle of each side a pointed tubercle, and the

mesosternum having a conical convexity. In form of body it is more elongate than any

species of Tylosis, but in the peculiarity of having 12-jointed antennz in both sexes it

agrees with that genus, and not with Oxoplus, to which it might otherwise be referred.

All three genera agree in the mandibles being broad and notched at their apices.

CROSSIDIUS (p. 81).

Crossidius trivittatus (p. 82).

Mr. Flohr has taken this species in some numbers at El Salto, near Huehuetoca, and

finds it extremely variable with regard to the dark stripes of the elytra. The extreme

varieties are,—one in which the elytra are wholly tawny yellow (with the exception of

a narrow sutural border), and another in which they are entirely dark brassy green. In

some examples the thorax has two or three large tawny spots.

The species agrees with Crossidius (besides the characters previously mentioned) in

the mandibles being broad and notched at the apex.

328 SUPPLEMENT.

The scutellum is not always prolonged behind into a sharp point; and there remains

no character of sufficient importance to separate the genus from Mannophorus, which

name will have the priority if the two genera are to be reunited. ‘The antenne in the

males are much longer, and in both sexes the eleventh joint is appendiculated; but

this latter peculiarity is shared in by Mannophorus forreri. The simple mesosternum

is the sole constant character which separates the genus from Sphenothecus (sensu

Dupont).

Named Leptocnemus sexualis, Chevr. (MS.), in the Sallé collection. The choice of

the specific name is enigmatical, the other sex of the species not being represented

in the same collection. But it is probable that Mannophorus ferreus is the female of

I. sexualis, and was known to Chevrolat, in which case the name would be applicable ;

the differences between the two in form and sculpture being very remarkable.

I have seen no specimen of Sphenothecus, in the large series of this genus examined,

which agrees with Dupont’s figure of S. tomentosus. One labelled S. tomentosus in the

Sallé collection is an approach to it, the central black stripe of each elytron having a

short white line in the middle, forming the commencement of a division of the black

stripe into two, but the thoracic marks are not different from the typical S. trilineatus.

S. tomentosus is probably a very rare variety or aberration of S. trilineatus.

To the localities given, add:—Muxico, Almolonga (Hége).

Nearly all Herr Hége’s numerous specimens differ from the typical form as figured

by Dupont in the lateral white stripe of the elytra being broad and reaching the apex.

An example of this variety in the Sallé collection is labelled “ S. lateralis, Chev.,

Mexico.” The specimen ticketed S. tomentosus, Dup., in the same collection is a further

varietal development, in which the lateral white stripe is still broader (leaving only a

very narrow margin of the black ground-colour) and the central black stripe shows the

commencement of a division into two.

Named Ischnocnemis luteicollis, Dugés, in the Sallé collection, but apparently not yet

described by its namer. Although it has much similarity in form and colours to

I. costipennis 2, it cannot be referred to the genus Jschnocnemis, on account of its

elevated and prominent mesosternum, which is the only constant character that

distinguishes Sphenothecus from Mannophorus and Ischnocnemas.

MUSCIDORA (p. 85).

As remarked above under the genus Deltaspis, Muscidora tricolor, Thoms., may

possibly be the same species as Deltaspis nigripennis; if this should prove to be the

case, and the slight characters which distinguish D. nigripennis from the other species

of Deltaspis be considered insufficient for generic separation, the name of the species

would stand as Deltaspis tricolor, Thoms. (D. nigripennis, Bates).

Four males from Taboga Island agreeing with Dupont’s description and figure, except

that the elytra are not narrowed at the apex, but obtusely rounded or subtruncated as _

in J. succinctus. In light-coloured examples a black fascia is faintly visible in the

position of the white belt of the elytra of ZT. succinctus. In other colours, in the broad

scutellum, and the roughened basal joints of the antenne the species resembles

T. succinetus, of which it appears to be a variety or aberration.

Trachyderes subpilosus (p. 89.)

To the localities given, add :—GuaTEMALA, Cerro Zunil (Champion) ; Panama (Boucard),

Trachyderes elegans (p. 90).

To the localities given, add :—Mexico, Juquila, Cordova, Oaxaca (Sadlé), Almolonga,

Tehuacan (Hoge); GuatemaLa, Coban (Champion).

The following is a beautiful colour variety, somewhat resembling 7’. hilaris:—

Var. T. eximius (Chev. MS.). Elytris nigris, fascia mediana (sicut in forma typica) testaceo-flava, macula

utrinque basali, altera majori apicali, suturam attingente, aurantiacis.

Hab. Mexico, Oaxaca (Sailé).

The prevailing form of the species, judging from a large series obtained by Herr Hige

at Jalapa, has light tawny-red or orange-brown elytra, with broadish black margins to

the median band; this is named 7. vicinus (Chevr. MS.) in the Sallé collection.

Individuals of 7. elegans sometimes approach very closely in colours light-coloured

examples of 7. subpilosus ; in such cases the testaceous-yellow lateral margin of the

elytra of 7. elegans, extending from the median belt nearly or quite to the shoulder,

will prove a good distinguishing character.

Examples of the black variety, more strongly punctured than others, and with denser

and longer hairs on the thorax, might be thought to constitute a distinct species, if this

form were not connected with the typical LZ. multifasciatus by numerous gradations.

Some of the Ventanas specimens have a dull reddish thorax, with distinct traces of the

characteristic black fascia.

In the description at p. 93, with reference to the length of the third antennal joint,

the word “again” was accidentally omitted; the third joint is about half as long again

as the scape. The male, as in the other species of the genus, is narrower than the

female.

Long. 3-54 lin. |

Hab. GuateMALA, Totonicapam 8500 to 11,000 feet (Champion). Under stones on

mountain-tops.

In the relative length of the third and fourth antennal joints and the scape this

species is intermediate between P. echinus and P. inequalis. In its ovate and strongly

tuberculated elytra it comes near P. echinus ; but in all the numerous examples the body

and elytra are conspicuously more elongate than in that species. The rough irregular

sculpture of the thorax and the interstices of the elytra form also a valid mark of differ-

ence from P. echinus.

PARMENA (to follow the genus Phrynidius, p. 93).

Parmena, Latreille, Régne Anim. ed. 2, v. p. 125; Lacordaire, Gen. Col. ix. p. 275.

A well-known European genus, hitherto supposed to be restricted to the Mediter-

ranean region: six species have been described. The following species has a close

resemblance to P. solieri, Muls., but differs curiously in important points of structure.

For example, the claws are decidedly more parallel, 7.e. “divergents,” according to

Lacordaire’s phraseology, whilst in Parmena they would be considered ‘“ divariqués ;”

they are not, however, so closely approximated as in the “‘ Niphonini” group, and seem

to vary a little in the tarsi of one and the same individual; thus it seems inexpedient,

at least until further specimens are obtained, to insist on the value of the character and

remove the insect to a quite different group, e.g. the “Apomecynini,” where it would

LONGICORNIA. 335

form quite an isolated genus. A further difference from Parmena is the rather widely

open suture of the anterior, and the decidedly open middle, acetabula.

1. Parmena villosa.

P. solieri simillima, differt elytris angustius ovatis thoraceque confertissime confluenter punctato. Sat

angusta, suboblongo-ovata, nigra, undique griseo-erecte pilosa et griseo-incumbenti pubescens; thorace

sicut in P. soliert; elytris sat confertim equaliter et minus grosse, hic illic sublineatim, punctatis; antennis

ab articulo 5° basi anguste griseis.

Long. 4 lin. Two examples.

Hab. Mexico (Sallé). Named Parmena villosa, Sturm, MS., in the Sallé collection.

MECYNOME (to precede the genus Moneilema, p. 98).

Corpus angustissime ovatum, mediocriter convexum, supra parum inzquale. Caput inter antennas concavum ;

tuberibus antenniferis oblique elevatis, apice obtusis; frons transversim quadrata; oculi infra sat angusti

obliqui, supra valde distantes. Labrum basi epistomate (sensu Lacordaire) munitum. Antenne corpore

longiores, sat graciles, filiformes, subtus sparsissime breviter setosze, scapo fere sicut in gen. Lezopo elongato,

basi intus angustato deinde usque ad apicem cylindrico; articulo 3° gracili, quam scapus longiori;

4° paullo breviori, ceteris brevioribus gradatim decrescentibus. Thorax subcylindricus, lateribus longe

post medium tuberculo parvo conico, deinde usque ad basin sinuato-angustatis, Elytra basi thorace

parum latiora, humeris obtusissimis, deinde usque ultra medium leniter dilatatis, versus apicem citius

angustatis, apice singulatim subacuminatis. Pedes mediocres; coxe antice salientes; acctabula extus

clausa; prosterno inter coxas depresso, angusto; mesosternum angustum fere planum; acetabula extus

clausa; pedes intermedii et posteriores valde approximati; femora gradatim clavata; tibie intermedix

extus paullo sinuate ; tarsi mediocres, articulo unguiculari sicut in Moneilema lato subdepresso; ventris

segmentum basale processu semiovato.

This peculiar form belongs to Lacordaire’s artificial group “ Parmenides.” In general

form it resembles most the New-Zealand genus Xyloteles, but its real affinity is in the

direction of Moneilema, or rather of Leptostylus and Idephrynus, of the “ Acantho-

cinini” group.

1. Mecynome enescens. (Tab. XXII. fig. 5.)

Fusco-snea, subnitida, parce setosa et subtiliter ochraceo-fusco incumbente pubescens ; elytris post mediam

MONEILEMA (p. 98).

Moneilema albopictum (p. 94). |

To the locality given, add:—Nortu America.—Mexico, Tehuacan (Hoge).

A good series of the forms of this genus allied to M, albopictum has been supplied

336 SUPPLEMENT.

by the collections of M. Sallé and Herr Hoge, among which all the species Nos. 2 to 9

can be recognized. Nearly all of them, including the extreme forms MM. albopictum

and WV. carinatum, were taken apparently together by Herr Hoge at Tehuacan; and as

connecting varieties are found with them, there can be little doubt that they are all

varieties of one and the same species.

Moneilema variolare (p. 95).

A very large series of this species was taken by Herr Hoge near the city of Mexico.

The difference between the sexes described by M. Thomson is tolerably constant, 7. ¢.

the male is more or less densely clothed with tawny-brown tomentum and the female

glabrous; but numerous females occur in which specks of tomentum are scattered over

the surface, and many males have the same character. Large glabrous female examples

(one inch long) agree fairly well with Newman’s description of W. blapsides, but it is

impossible to be certain that they are the same species.

the thorax rises uvruptly from the sides, and is thus conspicuous though not long.

The elytra have vertical sides, but without ridge separating them from the dorsal

surface.

Examples from the State of Panama are distinguishable from those of more northern

localities in Central America, as well as from those of South America, by the greater

breadth and continuity of the white sutural stripe of the elytra.

The five examples of this variety are more or less abraded and imperfect, but in the

Chontales form of D. nivea, chiefly on the lateral margins and on the disc, in the latter

situation being more or less confluent, and running into short transverse submacular

fascie. The disappearance of the lateral spine of the thorax in two female examples

from Chiriqui is remarkable, as it exists in a male from the same locality; in its place

is an obtuse tubercle. The spine, however, varies in form in the other specimens.

This largest and finest species of Hammoderus is dedicated to its discoverer Mr. F.

Sarg. The cretaceous spots of the elytra are more transverse than in the other species;

the base for some distance is quite free, but the other larger spots lie in the position

usual in the genus, viz. two lateral (one before and the other after the middle), and one

rounded on the disc near the apex; a rounded spot near the suture and the base

(existing in several other species) is also well developed, but between the two large

lateral spots, and nearly in the middle of the elytra, there is a large irregular patch

formed apparently of the agglomeration of many of the small transverse wavy streaks,

of which there are a great number, on the disc and near the suture.

This species, as defined by its original describer, varies very little throughout its

wide distribution ; the narrow white spots on the elytra are more or less numerous,

and the larger pale spot behind the middle of each elytron is more or less developed.

Specimens from the volcano of Chiriqui scarcely differ from those found on the

Amazons and near Rio de Janeiro. But in the plains of Chiriqui a colour-variety

occurs, conspicuous for the brighter fulvous hue of the head, the lateral stripe of the

thorax, and the curved baso-lateral stripe of the elytra, the latter margined with white

specks and enclosing (like the stripes of the thorax) a dark-brown central area.

In company with this species at Rio Janeiro, Bugaba, and in several localities in

342 SUPPLEMENT.

Guatemala, a slender species occurs coloured and marked exactly as in A. muticus and

assuming the same slight local peculiarities as the companion species. It has, however,

a cylindrical instead of a trapezoidal thorax and a plane mesosternum, with less retrac-

tile head. The latter structural peculiarities would make it a member of a distinct

genus (Tautoclines), according to Thomson and Lacordaire; I strongly suspect it to be

the male of A. muticus, but have no positive evidence of the fact. It is described

further on as A. consors.

Possibly the male of A. muticus, Thoms., notwithstanding the great difference in the

form of the pro- and mesosterna.

I have not yet seen examples of A. consors from the other localities in which

A. muticus is known to occur, viz.:—Amazons, Volcan de Chiriqui, Chontales, and

Mexico.

Mr. Squires took near Rio Janeiro specimens of a form very similar to A. consors,

but having the strongly convex mesosternum and other structural characters of

A. muticus. This is evidently the A. preustus, Thomson, and is more probably the

true male of A. muticus.

The single specimen described proves to be a colour-variety of the species, in which

the irregular blackish markings of the disc of each elytron are much developed in

darkness of colour and in extent. In all the other examples subsequently received the

elytra are pale ochreous-brown, with a sutural vitta (extending from the base to a little

beyond the middle) and a curved oblique subapical spot (not reaching the suture)

velvety black; the ochreous disc of the elytra is variegated (especially behind the

middle) with faint dusky spots and streaks.

Ptericoptus panamensis (p. 111).

To the locality given, add :—Panama (Boucard), Volcan de Chiriqui (Champion).

In most examples the elytra have on each side near the apex a curved black spot

which does not extend towards the suture as in the specimen which served in

originally describing the species. The antenne are much shorter and thicker than

in P. caudalis.

Belongs to Desmiphora rather than to Pyrrhacita, jadging from the shorter antennal

scape, but differs from both in the absence of the characteristic hair-tufts. The long

erect hairs approach, however, on the vertex and the anterior margin of the thorax, the

tufted form. The vertex is much longer, and the upper part of the eyes more distant

from the thorax, and the antenne more slender than in typical Desmiphore.

The thorax is simply angulated in the middle of the sides as in LE. flavocinctus. The

antennal joints 5-11 are not so strongly abbreviated as in the typical Hupogonii; they

are, however, all singly very much shorter than either the third or the fourth, which

proportion constitutes one of the chief characters of the genus.

The first to the fourth antennal joints are densely clothed with long hairs all round,

the fifth to the eleventh are ciliated beneath only. The species therefore approaches

very nearly the genus Atelodesmis, from which it differs in the slender form of the third

and fourth joints. Hupogonius ursulus has antenne similarly clothed, but with the

shortened fifth to eleventh joints somewhat dilated on one side.

Unelcus, Thomson, Syst. Ceramb. p. 109 (1864) ; Lacordaire, Gen. Col. ix. p. 627.

Five species of this genus have been described, all tropical South-American. It is

distinguished from Eupogonius (with which it agrees in the long erect hairs which

clothe the body and limbs, and in the simple middle tibie) by the head being rather

deeply concave between the antenne, the joints of the latter from the third gradually

diminishing in length, and by the lower lobe of the eyes being elongated.

The species on which this genus is founded has the ordinary appearance of a small

Monohammus; but its structural characters are the same as those of the group

“ Apodasyides” of Lacordaire. It has probably a real affinity with Hupogonius and its

allies, though destitute of the long hairs which clothe the body and antenne of nearly

all the members of the group.

ESTOLA (p. 118).

Dr. Horn has remarked, with regard to the Californian EHstola (2) sordida, that it

differs from Lacordaire’s definition of Estola, and probably does not belong to that

genus. This is quite true; it forms with E. perforata and the three species presently

to be described, viz. EL. fulvitarsis, E. prolongata, and E. leucosticta, a distinct group

differing from Lacordaire’s Estola in the broad and short lower lobe of the eyes and

gradually sloping mesosternum; the granulation of the eyes and form of the scape offer

no essential difference. But the form of the lower lobe of the eyes and of the meso-

sternum is not constant, but varies gradually in the score or so of South-American Lstole

which I have examined. Still there remains sufficient difference to distinguish the FE.

sordida group. It remains to be seen to which group the original Hstola of Fairmaire

is to be referred.

Esthlogena porosa, but with the difference that the elytra are faintly punctate-striate,

with many small punctures besides the larger black ones. Some examples of the

typical E. perforata from Chontales have nearly the same elytral sculpture, and these

The very small species which constitutes this genus would no doubt be included, on

account of the near approach to closure of the middle haunch-sockets, by Lacordaire

in Division Il. of his ‘“‘ Acanthocinides.” This character, however, exhibits such fine

gradations in the allied forms, and is of such unsatisfactory application, that I think

most of Lacordaire’s Division II. will eventually be referred to the ‘‘ Pogonocherini.”

PENESSADA (to follow the genus renea, p. 121).

Penessada, Thomson, Physis, ii. p. 97; Lacordaire, Gen. Col. ix. p. 664.

One species only of this genus has been described as yet, from Brazil; we now add

three others from Central America.

1. Penessada fuliginea.

Elongato-ovata, fusco-nigra, scutello ochraceo-pubescens elytrisque dimidio postico fulvo-ochraceo maculato vel

variegato ; capite quam in gen. Zrenea multo minore angustioreque, confertim punctato, inter antennas

Long. 34-4 lin. ¢ Q.

Hab. Guatemaua, Cerro Zunil, Panajachel (Champion).

Resembles, in general appearance, the genus Alphus or Leptostylus much more than

renea, to which it is really allied in structure. The claws are not so closely parallel,

nor the claw-joints so thick, as in the “ Niphonini” and “ Apomecynini,” and they vary

in degree of divergence in one and the same individual. Its characters bring it within

the definition of the genus Penessada.

2. Penessada albosignata. (Tab. XXII. fig. 21.)

Oblongo-ovata, castaneo-rufa, glabra; scutello elytrorumque fascia (utrinque abbreviata) prope apicem cano-

Long. 43 lin.

Hab. Guatemata, Cerro Zunil (Champion).

One example only.

Agrees in generic characters with the preceding species; the middle tibie having the

groove on their outer edge concealed by an even fringe of short hairs, and the long sharp

claws being rather less approximated and subparallel than in renea.

3. Penessada (?) asperata. |

Precedentibus magis elongata capiteque latiori. Obscure fulvescenti-fusca, fusco obscuriori nebulosa, setis

incumbentibus albis undique sparsim obsita ; capite (preecipue inter antennas) lato, vertice et occipite linea

profunda impressis ; thorace subquadrato, tuberculo laterali valido, acuto, dorso inewquali, tricalloso, cum

capite grosse sparsim punctato ; elytris elongato-ovatis, postice gradatim angustatis et leniter declivibus,

crassius oblongo-clavato basi intus subito angustato, articulis apice (6°-11™ basi et apice) anguste griseis.

Long. 5-6 lin.

Hab. Mexico, Jalapa (Hége).

Two examples.

The difference in the width of the head and its less deep concavity between the

antenne, the sinuation of the middle tibie and the thicker (almost tumid) scape, almost

warrant the generic separation of this species from the two preceding. It agrees with

them, however, in other important generic characters, and may be nearer the type

species of Penessada (which I know only from description) than the other two. The

claws are less long and sharp, and decidedly more approximated.

Group PHACELLINI (to precede the Group Onciderini, p. 121).

EURYCALLINUS.

Corpus breviter ovatum, convexum, subtiliter incumbenti-pubescens, parcissime setosum. Caput sicut in

A genus intermediate in its characters between Phacellus and Brachychilus, the only

other known members of this distinct group. The sternum and acetabula are con-

structed as in those genera.

The unique species on which this remarkable genus is founded has hitherto been

met with only in the Amazons region.

Hab. Panama, Divala (Champion).

One example.

Agrees closely with examples from the Amazons, with which I have compared it.

MYRMOLAMIA.

Gen. Cyrtino (Leconte) affinis, differt elytrorum humeris rectangulatis apice obtusis. Corpus minutum, glabrum,

breviter oblongum, angustum. Caput latum inter antennas planum ; oculi parvi, divisi; palpi apice

tenuiter acuminati. Antenne filiformes, subtus setis nonnullis valde elongatis; scapo valde elongato,

gradatim graciliter clavato, arcuato ; articulis 39-11” multo brevioribus, gradatim sed parum decrescentibus.

Thorax inermis, cylindricus postice angustatus et valde depresso-sulcatus, vel cyathiformis dorso anteriori

valde convexo. Elytra basi depressa; postice modiocriter convexa, tuberculo valido compresso utrinque

Femora pedunculata et fortiter clavata ; tibiee intermedi extus sinuate. Ungues sub-

centrobasali.

divergentes.

Separated from the North-American genus Cyrtinus with much hesitation, as it

agrees with Leconte’s description of that genus (Smithson. Contr. 265, pt. ii. p. 333)

pretty closely in all respects except the “ elytra with rounded humeri,” the shoulders

being as rectangular as ¢. g. in Pogonocherus mixtus, Hald. The elytra, however, widen

a little posteriorly: they are gradually declivous behind, and jointly subacuminate-

rotundate at the apex; they are not “very convex,” nor can the centro-basal tubercle

be called “a large acute spine,” which Leconte attributes to Cyrtinus.

3a2

364 SUPPLEMENT.

The position of Cyrtinus and its allied genera in the Lamiide series of forms is very

doubtful. Lacordaire placed the group after the ‘Exocentrini” division of the

“ Acanthocinini,” from which alliance Leconte widely removed them, making them a

distinct tribe, not far removed from the “ Moneilemini.” The question cannot be satis-

factorily determined in the absence of connecting forms, graduating in the direction of

one or other of the great groups of Lamiide, of which they may be eccentric develop-

ments. The subparallel position of the tarsal claws is mentioned by Leconte in

speaking of Cyrtinus, but he says the claws appear to be movable, and are sometimes

divaricate. I have already remarked on the similar variability of position of the claws

in speaking of Parmena villosa and Penessada fuliginea.

The Myrmolamiz resemble ants of similar size and colours. They also have a strong

analogical resemblance to Huderces and Tillomorpha of the family Cerambycide.

1. Myrmolamia opacicollis, (Tab. XXII. fig. 23.)

Castaneo-nigra, elytris plaga transversa versus basin (cano-pubescenti), sutura postice et marginibus testaceo-

LAMIESSA (to precede the group Onciderini, p. 121).

Forma anomala, gen. Hwmolpo similis. Corpus breviter oblongo-ovatum, longissime erecte pilosum. Caput

valde retractum, inter antennas latum planum, tubera antennifera nullomodo elevata ; frons quadrata ; oculi

subtiliter granulati, lobo inferiori sat angusto. Antenne 9-articulate, corpore haud longiores, filiformes,

undique sparsim setose ; scapo sicut in Hstolis typicis, brevi, sed gracilius clavato, articulo 3° quam scapus

dimidio longiori, 4° quam precedens paullo breviori et crassiori, 5°-9" multo brevioribus. Thorax

cylindricus, medio perparum dilatatus, inermis, dorso anteriori valde convexo. Elytra ovata, convexa,

apice rotundata. Prosternum angustum, inter coxas exsertas depressum, acetabulis extus angulatis;

mesosternum fere planum; cox posteriores distantes. Pedes mediocres, longe pilosi; tibie sat latee,

intermediz extus simplices; ungues divaricati, basi lati.

Unlike any other genus of Lamiide known to me.

In its structural characters it comes somewhat near to the Pogonocheri and Eupo-

gonw; but in the thorax and head it most resembles certain genera belonging to the

true “Saperdini.” It is therefore probably an aberrant form of Saperda, remarkable

for its relatively short and broad elytra.

Liable to be confounded with Plerodia degenera, but distinguished from it by the

more strongly clavated scape and the flexuous third antennal joint, as well as by the

much shorter humeral carina; there is the rudiment of an elongated carina, but it is

not sharp and polished as in Plerodia. From very small and unusually narrow indi-

viduals of Hypsioma picticornis, to which species it is very closely allied, it differs again in

Closely allied to, if not the same species as, P. singularis (Thoms. Physis, ii. p. 61)

from Cayenne. A specimen is labelled, evidently in error, Hypomia mewvicant, Thoms.,

The genus Plerodia differs very slightly from Hypsioma, its chief differential

characters being the very gradually thickened scape, carinated elytral shoulders, and

more oblong form.

The only species of this genus that has been described is from South Brazil. The

following small and obscure species agrees with it in generic characters, viz. the much

shorter and less plane forehead, the head wide between the eyes, with the apex of the

antenniferous tubercles prolonged into horn-like processes curving outwards. The

general form is elongate oblong.

Distinct from O. putator by its more robust form, broader thorax, and especially by

the much scantier and smaller black granules of the base and middle of the sides of the

elytra ; the granules, in short, do not assume the size of the round polished tubercles

of O. putator, except on and below the shoulders.

Distinguished from O. putator and 0. senilis, to both of which it is almost equally

partly in rows, these spots in O. ocellaris being, instead of whitish as in those species,

of a rusty-red colour, with a paler speck in the centre of each.

Examples from Cerro Zunil are less variegated than the typical specimens from

The apices of the elytra also are much less divaricated than in the typical examples.

They are distinguishable, however, from similarly coloured specimens of S. protensa

by the ventricose and punctate-striate elytra. In S. protensa the punctuation is con-

fused. The following is apparently an extreme, elongated variety of this species :—

The only structural difference between this species and D. furcula is in the less

prolonged apices of the elytra, which also are less close together, owing to the less

oblique truncature, which leaves plainly visible the marked sutural angle. To this

peculiarity, however, is added one of elytral markings, D. lignea having always a long

arcuated cinereous spot in the middle of each side, of which there is scarcely any trace

in D. furcula.” The dark brown circumscutellar spot is in both rather short and.

quadrate, and bordered externally by a very broad ashy-white vitta, which curves from

the shoulders to the suture. In both species the upper lobe of the eyes is very narrow,

scarcely broader than the narrow band which connects it with the lower lobe. The

ciliee of the antenne are very short and less dense than in D. Oryx.

A genus having no near affinity with any other American form of Lamiide, except

perhaps the genus Anoreina, Bates. In facies it most resembles certain undescribed

African species allied to Frea and Dichostates ; but it differs from the group “ Crossotides,”

to which these belong, in having a distinct sinus on the outer edge of the middle tibiz.

From the American group “ Anisocerides,” with which it agrees in the gaping outer

rims of the anterior and middle acetabula, it differs in the form of the scape, which

is that of the great majority of the Estolides, Apodasyides, and Pogonocherides of

Lacordaire, and of the genus Oreodera. The head is strongly retractile as in the

Crossotides, the mouth resting in repose on the broad prosternum between the prominent

anterior haunches. ‘The position of the genus seems to be between the African

“ Crossotini ” (especially Humémetes) and the American “ Oreoderini,’ through the genus

Anoreina of the latter group, which differs from Xenofrea in its ciliated and bristly

antenne, the sharp notch nearer the middle of the intermediate tibie, and the acetabular

suture of the anterior haunches nearly closed as in Oreodera.

The Venezuelan 8. larva proves to be only a geographical variety of the Mexican

S. histrionica, when a long series of specimens from intermediate localities is examined.

The structural peculiarities mentioned by Chevrolat are of no value, as they vary according

to the degree of development of the insect; the colour of the pubescent stripes on the

elytra is very similar in the specimens from all the localities, and the only differential

characters which seem to be really distinctive are the greyish-white spots on the sides

of the thorax, under the shoulders of the elytra, and on the disc of the latter. I have

seen specimens with these spots, in Central-American collections, only from the Isthmus.

sinuate-truncate elytral apices. It is distinguished from other described species of its

group (except from A. sylvanus) by the compact yellowish-white tomentum which

clothes its square flat forehead; the elytral carine diverge, and become a little more

elevated towards the base, and are there granulate-tuberculated ; a few much-scattered

granule are seen also between the carine and the shoulders. The colour of the elytra

is lightish brown, becoming ashy brown towards the suture, and much spotted with

dark brown; there are also three or four lateral much-angulated dark-brown fascie or

patches, but no distinct whitish fascia. It ranges insize from 6 to 9 lines. The meso-

sternum in front is subvertical, with a tubercle on each side of the edge of the declivity.

This well-marked species, of which Mr. Champion took a very large series, bears a

curious resemblance to A. cornutus, which is also from Guatemala, but known only

from a single example ; the structural difference, however, forbids the supposition that

they may be varieties of one and the same species. There is no tendency in A. arietis

towards the great elevation of the latero-dorsal tubers of the thorax, and the projection

of the base of the elytral carine which distinguish .4. cornutus; the general colour, too,

and the form of the yellowish ram’s-horn marking across the suture are not quite the

same.

deres on the same grounds as Discopus, Pteridotelus, Tetrasarus, and Plagiosarus are

separated, namely, differences in the clothing and structure of the antenne. In all

other respects these genera agree with Acanthoderes, and in some of them the con-

tained species have little resemblance to each other, except that which their antennal

structure gives them.

The typical species of Sychnomerus has greatly the appearance of a Pteridotelus ; but

it wants the dentiform processes of the undersides of joints 7, 9, and 10 which charac-

terize that genus; what seem to be such processes in Sychnomerus prove on close

examination to be dense tufts of hair.

One example only. The antennz are rather more densely tufted at the apex of the

third and fourth joints, and therefore approach the structure of the genus Tetrasarus ;

but the long beard of black hairs at the apices of the third and fourth joints does not

form a compact brush as in that genus; it depends from the under surface only, and

is repeated on all the following joints from 6 to 11.

antenne do not differ from those of the group in which these members are short and

to deal with a type distinct from Acanthoderes.

All Mexican examples I have seen and some Guatemalan ones differ from those

found further southward in the tarsi being blackish above with grey pile and fulvous.

below only, the southern form having fulvous tarsi; this difference is important, as it

is one which also differentiates LZ. rogersi from the southern form of L. binuwmeratus.

Thomson gives Mexico as the locality of his L. binumeratus, so that his phrase “ tarsi

flavescentes” probably originates in hasty observation, the colour appearing yellowish

when viewed sideways. I formerly described the species from Chontales as L. v-album,

which may now be restored as the name of the Southern form. The two forms may

be discriminated as follows :—

1. L. binumeratus, Thomson. Tarsi supra nigri, griseo-pubescentes, subtus fulvo-testacei.

Hab. Mexico; Guatrema.a, Capetillo.

Lagochirus rogersi (p. 146).

To the locality given, add :—Costa Rica (Van Patten); Panama, Volcan de Chiriqui

(Champion).

In this species the tarsi are above black, clothed with grey pile, beneath tawny ashy

and partly black, therefore darker than in the Mexican L. binumeratus. From the

latter L. rogersi is distinguished, in most of its examples, by its much larger size, and

especially its elongated elytra, and by the whitish letter-like elytral fascia being less

definite, running across the elytra and duplicated behind; but some specimens are as.

small as L. binwmeratus, and not conspicuously more elongated, and the white marks.

are sometimes much less developed, so that the species are closely allied.

Certainly distinct from L. leucopygus, in which the anterior margin of the grey apical

area is arcuated. The thorax also is different in outline, the sides being much narrowed

and sinuated behind the prominent lateral tubercles. In L. lewcopygus the thorax has

the same form as in L. macula, Say, viz. with feebly rounded sides, and more narrowed

in front than at the base.

Belongs to the same group as the preceding species ; the pro- and mesosternum are

equally broad. The first and third antennal joints are marbled brown and grey. The

centro-basal tubercles of the elytra are slightly elevated and pubescent, but the smaller

dusky tubercles arranged in rows are scarcely elevated and naked. The basal joint

of the hind tarsi is as long as the second and third taken together.

ELEOTHINUS (p. 154).

This genus is evidently equivalent to the North-American group of Leiopus defined

by Dr. Horn (Trans. Amer. Ent. Soc. viii. p. 124) as embracing L. wilti, L. crassulus,

and J. fascicularis. It seems to me sufficiently different from the type of Letopus (the

European L. nebulosus) to justify generic separation. I find, however, that the third

species I referred to the genus, viz. L. comus, does not belong to it; besides the long,

erect, soft hairs with which its elytra are clothed, it differs in its extremely narrow pro-

and mesosternum, in which it resembles Lepturges; it will be found further on, under

the genus Eutrichillus.

Among Mr. Champion’s later captures is a small Longicorn, of shorter ovate form

than the North-American Lleothini, which bears the closest possible resemblance in

general form and colours to many Leptostyli, but is evidently much nearer Letopus.

Although its antenne are much longer and finer, and the short hair-tufts of the elytra

are reduced to a scarcely perceptible black pubescence on the narrow centro-basal tuber--

cles, I here describe it as an Kleothinus (E. pygmeus).

Liopus, Horn, Trans. Amer. Ent. Soc. viii. (1880), p. 123 (partim).

Excluding the species with hair-tufts on the elytra, this genus is taken here as defined

by Dr. Horn. It comprehends those allies of the type Leiopus nebulosus of Europe

which have a very narrow prosternum, a mesosternum of very moderate width, oblong,

more or less narrowed behind, and hind tarsi of short or medium length, in which the

basal joint is as long as or a little longer than joints 2 and 3 taken together. As thus

defined, it comprises a small number of described species from the North Temperate

zone of both the Eastern and Western hemispheres.

The following species are somewhat aberrant, but agree better with Leiopus than

with Nyssodrys or any other allied genus.

To the localities given, add:—GuatemaLa, Volcan de Atitlan (Champion); PANaMa,

Volcan de Chiriqui, Bugaba (Champion).

All the examples from Guatemala and Nicaragua differ from those from the State of

Panama in the centro-basal ridges of the elytra being very slightly elevated, but crested

with a pencil of very long hairs. . Those from Panama have a strongly elevated com-

pressed ridge fringed at the summit with very short hairs; these agree better with

Pascoe’s description of A. privatwm from Santa Marta. In colours and markings the

two forms offer no difference.

The two forms may be separated as follows :-—

A. privatum, Pascoe.

Hab. Panama, Volcan de Chiriqui, Bugaba (Champion).—Sovutn America, Colombia.

A. privatum, var. penicillare.

Hab. GUATEMALA; NICARAGUA.

In both forms the anterior tibiee of the male are bisinuous on their inner edge, with a

more or less prominent tooth between the two sinuations. ‘This structure (observable

in a less degree in other species of the genus) is seen in a still more developed state in

A, brachiale, which is easily distinguishable from A. privatum by the short black oblique

macular fascia behind the middle of the elytra.

The scape in all three forms is very strongly flexuous beneath and hairy.

Lepturges, the hind legs, though elongated, being much less so than in the typical

Anisopodi, the hind femora very gradually clavate (thicker in the male than in the

female), and the elytral epipleure not being separated from the dorsum by a sharp line

The Cerro Zunil form, whose differential characters are enumerated under the head

of this species, proves too constant and distinct to be maintained as only a variety.

The locality ‘Cerro Zunil” must therefore be erased, and a new species distinguished

as follows :—

The form of the thorax and the colour of the antennz and legs are nearly the same

as in L. multinotatus; but the colour and markings of the elytra in the latter are

constantly different, the spots on a grey ground being much more clearly defined, short,

and oblong, very numerous, widely separated on the anterior part of the disc, but more

or less confluent on the sides and towards the apex.

Lepturges laticollis (p. 169).

The pretty elytral markings are seen to vary considerably in a long series. In the

type form the grey apical area (after the broad dentated black belt) has on each elytron

a triangular blackish spot, leaving a grey margin between it and the suture and black

belt. The extreme varieties (chiefly from Chiriqui) are:—1, apical area blackish, sepa-

rated from the deep black belt by a grey fascia; 2, apical area clear ashy-grey. The

black belt is sometimes very broad, and then encloses on each elytron a whitish lineole.

The size of the species varies from 1 to 1% line.

Hab. Guatemaa, Cerro Zunil (Champion).

In both L. complanatus and L. amabilis, from the Amazons, the subapical black

spot of the elytra is narrow and transverse ; in L. callinus it is quite as long as broad,

and surrounded bya grey margin. The similarly coloured and closely allied L. gratiosus

has no separate subapical spot, and is besides distinguished by its much longer,

sharply truncated elytra.

Resembles Z.. deliciolus, from the Amazons, so closely that I should have treated it as.

only a geographical variety of that species had it not been for the rounded apices of the

elytra, these organs in L. deliciolus being sharply truncated. The elytral spots are in

the same position in both, though slightly different in shape ; the spot on each side of

the scutellum especially is markedly different ; in L. delictolus it is not obliquely ovate,

broadened to the base, as in L. charillus, but transverse quadrate, distant from the base,

and prolonged behind for a short distance down the suture.

Coloured and marked nearly as in L. physoderus, and the thorax similar in shape;

but the general form of the body is that of Anisopodus, to which genus also it approxi-

mates in the somewhat lengthened hind legs, so different from the Lepturges of the

L. tumidicollis group, which have short hind legs and shorter and thicker femora. The

gradually sloping epipleure of the elytra, however, forbid the species being associated

with Anisopodus.

1. Dectes (Leconte, Horn). Elytra densely clothed with erect sete; scape of the

antenne scarcely flattened beneath. D. spinosus, D. texanus.

2. Canidia (Thomson). Elytra with few and scattered incumbent sete, or naked;

scape of the antenne broadly flattened or even grooved beneath. D. mexicanus,

D. spinicornis, D. balteatus, and C. cincticornis, Thoms. (allied to D. balteatus).

OXATHRES (p. 174).

This genus must be withdrawn from our fauna, our species O. pictulus, on further

examination, proving to have a different form of ovipositor in the female from that

which is characteristic of Oxathres, in which the dorsal plate of this organ tapers to a

sharp point, and is in the typical species carinated down the middle. In O. pictulus,

though the bispinose ventral plate resembles that of Oxathres, the dorsal plate is broad

and obtuse at the apex. The species must be placed in Vyssodrys, near WN. calligramma.

SPHENOPSILUS.

Gen. Oxathri affinis. Corpus scaphiforme absque setis. Caput parvum, angustum ; oculi subtiliter granulati,

lobo inferiori subtriangulari, elongato. Antenne corpore vix longiores, tenues, articulis 1°-4™ subtus

ciliatis, scapo valde elongato, gracili, apice clavato. Thorax graciliter trapezoideus, inermis, post medium

vix rotundato-dilatatus. Elytra postice curvatim attenuata, apice sinuato-truncata, angulis externis valde

productis. Prosternum et mesosternum angusta, illo valde arcuato hoc alte tuberculato. Pedes validi;

femora gradatim incrassata; tarsi articulo 1° quam 2" et 3" conjuncti haud longiori.

o. Segmentum apicale dorsale apice arcuatim emarginatum, ventrale latius, angulis acute productis.

%. Segmentum apicale mediocriter elongatum ; dorsale late lanceolatum dorso subcarinato apice in denticulum

prolongato ; ventrale semitubulare apice sinuatum, angulis productis acutis.

The species for which this genus is rendered necessary has little resemblance to any

other member of the “ Acanthocinini” group. The body is much narrowed anteriorly,

including the head, and rather more gradually posteriorly; the antennal scape is long

and slender, and clavate at the tip. The apical abdominal segment in both sexes is

constructed nearly as in Oxathres, but the dorsal plate in the female is shorter and

broader.

NYSSODRYS (p. 178).

The characters of this genus given in the original description cited, with the addition

and correction at pp. 177 and 178, may perhaps suffice to distinguish it from Leiopus,

Lepturges, Toroneus, and the numerous allied genera; but the study of many new

species since discovered, and a re-examination of those previously described, reveal so

great a diversity of forms that I doubt much if the genus can be maintained as hitherto

defined. The elongate-ovate, convex species, with short stout legs, thickened posterior

femora, short basal joint to the posterior tarsi, and elongate-oblong lower lobe of the

eyes, I have already transferred to Atrypanius. I now propose to remove certain other

species, which have longer hind legs with long peduncles and rather abruptly formed

club to the femora, and a longer first tarsal joint, to the genus Sporetus, notwithstanding

the absence, or at least the extreme paucity, of elytral sete. Nyssodrys guttula and

N. vitticollis come within this category; and they agree better with Sporetus than with

Nyssodrys in style of markings, and in the presence of a few short rigid bristles on the

upper as well as the numerous sete on the underside of the antenne.

The following is a rearrangement of all the species known to me.

Sarstoon (Blancaneaur); GuateMALA, Cerro Zunil, Volcan de Atitlan, Las Mercedes,

Torola, Mirandilla, Sabo (Champion); Panama, Volcan de Chiriqui, Bugaba, David

(Champion).

One of the commonest species of Longicornia in Central America. NV. contempta

belongs to a group differing from the typical Nyssodrys (e. g. N. caudata) by the much

shorter ovipositor in the female, and the shorter and more thickly (though gradually)

clavate hind femora, the more convex and ovate form of body, and shorter basal joint of

the hind tarsi. The group is allied to Atrypanius, of which it has the form of thorax; it

contains several species with stouter and shorter-jointed antenne, and others with very

long capilliform antenne; to it belong, of already described species, WV. binoculata,

N. lignaria, N. cinerascens, N. lentiginosa, N. corticalis, N. grisella, N. spreta, Lep-

turges lineatocollis, and the four following :—

Differs from the other species of this section of Myssodrys in the less elongated and

subtriangular form of the lower lobe of the eyes. The pro- and mesosternum are nearly

as in Leiopus nebulosus; and I should have placed the species in Letopus had the

antenne not differed so greatly from that genus in their length and tenuity.

Closely allied to WV. efflicta, which has in some examples a similar slender subapical

The three preceding species belong to the typical group of Myssodrys, distinguished

414 SUPPLEMENT.

by the long ovipositor of the female, the dorsal segment of which is sharply pointed,

and the ventral truncated or sinuated, and by the elongate-oblong, subdepressed form

of body, the very gradually thickened hind thighs, and longish basal joint of the hind

tarsi. The lower lobe of the eye is large and oblong, and the pro- and mesosternum are

of considerable width. To this group belong, besides the foregoing, Nyssodrys signifera,

N. propingua, N. simulata, N. efflicta, N. rodens, and N. excelsa, all from the Amazons,

and WV. conspicillaris, Er., from Peru; to the same group belongs a subgroup of species

including WV. incisa, NV. stillata, and NV. anceps, and NV. inclusa described below. Aber-

rant species of the group, having much thicker (elongate-clavate) hind thighs and

broader and shorter lower eye-lobes, are WV. alboplagiata, NV. lineolata, and N. ramea

from the Amazons.

simis tenuibus castaneo-rufis, articulis apice fusco-nigris subtus et supra (multo sparsius) setulosis; oculis

lobo inferiori oblongo mediocriter elongato; thorace quam in WV. caudata angustiori, minus trapezoideo,

longe ante basin angulatim dilatato (nec spinoso nec tuberculato); elytris apice sinuato-truncatis, angulo

suturali acuto, exteriori sat longe producto; pedibus sicut in MW. caudata; mesosterno late quadrato,

postice haud angustato; prosterno multo angustiori.

Long. 33-4 lin.

Hab. Panama, Bugaba (Champion).

A member of a subgroup having nearly all the structural characters of the NV. caudata

group, including the long tubular female ovipositor with truncated ventral segment, and

the emarginated dorsal and ventral plates of the male apical segment, but differing in

colour and markings—olive-black, spotted (the spots variously agglomerated) with light

greyish-ashy. The short sete on the antenne indicate an affinity with Sporetus.

III.

Nyssodrys polyspila (p. 180).

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

Belongs to a distinct group, characterized by the smaller and shorter lower lobe of

the eye (which is somewhat narrowed below), by the thorax being angulated (not spined)

some distance from the base, the elytra transversely truncated, with the external angle

toothed, the mesosternum broad as in Leptostylus, and the prosternum proportionally

broad. The female ovipositor in the majority of the species is short and flattened,

with the dorsal segment broadly rounded at the apex, but there are others closely allied

in other respects in which the same segment is rather pointed.

The species with obtuse ovipositors are closely allied to Sympagus, and might very

well be removed to that genus, notwithstanding their more elongate and flattened form

One example only. The head in front, as in WV. polyspila, is obliquely retracted, the

lower lobe of the eye rather short and narrowed below. In JW. (Leiopus) polyspila, as

White states, the thorax has numerous whitish spots, and each elytron from eighteen to

twenty spots.

flavo-testaceis.

Long. 24-37 lin.

Hab. Panama, Bugaba (Champion). Numerous examples.

In WN. letifica the blackish sutural and discoidal stripes of the elytra end abruptly

long before the apex, and are succeeded by a broadish straight fascia of the ashy-grey

ground-colour, the margin and apex being spotless, or faintly clouded with fuscous. In

NW. polytenia the sutural vitta (of irregular width) continues very nearly to the apex,

and there is no grey fascia, the submarginal vitta reaching nearly to the suture, posterior

to the end of the sutural vitta. The thorax, as in WV. letifica, is slightly dilated and

angulated some distance from the base. Both species have slenderer hind femora than

N. polyspila and other species of the group; but in the very short and flattened female

ovipositor, with rounded dorsal segment, they agree with those species.

Generally distributed along the forest-region of the Guatemalan Pacific slope

(Champion).

In NV. pictula the apical ventral segment is bispinose as in Oxathres, but the female ovi-

positor is not elongated and narrowed, with pointed and carinated dorsal plate, as in that

genus. The species, in fact, approaches in structure very nearly WV. calligramma, having

nearly the same form of thorax (angulated behind the middle), very broad mesosternum,

and short lower lobe of the eyes; the apparently bispinose apical ventral segment results

from the much deeper sinuate-truncature of the segment; the ovipositor is not much

longer than the male apical segment, but is narrower, and the dorsal plate is obtusely

rounded at the apex. The hind femora are rather more robustly clavate than in

N. calligramma*.

* A very similarly-coloured species of this group, with short lower lobe of the eyes, and interesting

from the fact of the apical ventral segment having no trace of spiniform lateral angles in either sex, is the

following :—

Nyssodrys buckleyi, n. sp.

Magis convexa, purpurascenti-cinerea; ‘elytris utrinque macula obliqua post scutellum fasciaque postmediana

a distinct spine near to the hind margin. The pro- and mesosternum are distinctly

narrower (not much broader respectively than in Leiopus nebulosus), and the female

ovipositor has the dorsal segment bluntly pointed, or ogival at the apex. The following

The species varies in size from 24 to 4 lines, and there are gradations between the

typical examples and the variety in the extension towards the apex of the long and

broad yellow humeral vitta.

To the locality given, add :—Muxico, Almolonga (Hége), Juquila (Sallé), Tehuantepec

(Sumichrast).

- One example from Almolonga is smaller (43 lin.) than Chontales specimens, and one

each from Juquila and Tehuantepec much longer (7-74 lin.). The Tehuantepec insect

does not differ from the typical form in markings, but the specimen from J uquila

(a female) has a peculiar appearance, owing to the more compact and less spotted ashy

tomentum of the elytra, and to the black dorsal vitta of the thorax being entire, or not

divided into two spots, the side of the thorax having also an additional ashy vitta.

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

Differs from C. superba and C. grandis only in the number and position of the black

markings; but in these differences the large series of individuals exhibit unwavering

constancy. Besides the absence of distinct black spots from the thorax, the chief

LONGICORNIA. 421

difference lies in the second pair of round black spots of the elytra being always widely

distant from each other, and in the presence of a smaller spot on the suture, between

the first and second pair; so that, viewed from above, the basal half of the elytra is seen

to bear five black spots in a regular position, thus °°

Captured in abundance by Mr. Champion on fallen timber in recently burned forest-

clearings.

TAPEINA (p. 191).

Tapeina transversifrons (p. 192).

To the localities given, add:—Panama, Volcan de Chiriqui, Bugaba (Champion),

Matachin (Schunke).

2. Tapeina (?) nudicornis.

T. transversifronti 2 similis, sed differt :—corpore minus depresso; antennis setis parvis sparsissimis absque

pubescentibus, tarsis latioribus.

Long. 23-4 lin. 9?

Hab. Mexico, Oaxaca, Cerro de Plumas (Hége).

Three examples, offering no dilatation of the head, and therefore presumably females.

Although deceptively similar to Tapeina transversifrons, 2, it is doubtful, considering

the shorter and thicker clavate scape and narrower sterna, whether it can be retained

in the same genus. The widely-gaping outer rims of the anterior and middle acetabula,

and the position and form of the conspicuous notch of the middle tibie, do not differ.

BACTRIOLA (to precede the genus Eumathes, p. 192).

Gen. Sepiseuthi (Thoms.) proxime affinis. Corpus lineare, tomentosum. Caput inter antennas concavum,

422 SUPPLEMENT.

A single example from Chiriqui, with which a specimen received as from “ Brazil ”

agrees in every respect, except that the ashy-grey adpressed pubescence is not so clearly

defined and the general colour more castaneous, owing doubtless to immaturity.

2. Bactriola paupercula.

Drycothea sallzi (p. 193).

To the localities given, add: —Britiso Honpuras (Blancaneaux); GUATEMALA,

Cahabon, Las Mercedes, El Reposo, El Tumbador (Champion).

This species differs from D. stictica, which it very much resembles in colour, by its

shorter form and relatively larger, especially broader, thorax. More definite points

of difference are the small lower lobe of the eyes, narrowed below, and the slightly

convex mesosternum in D. saliwi; the lower lobe of the eyes being very large and

broad, as broad or broader below than above, and rounded on the inner side, and the

mesosternum gibbous, in D. stictica.

4. Asemolea minuta. -

Callia minuta (p. 195).

‘This insect must be transferred from the genus Callia to Asemolea. It is closely allied

to the preceding species, on account of the unarmed thorax and thickened antenne.

CALLIA (p. 194).

This genus comprises two groups, characterized as follows :—

Caria proper.—Vertex inter antennas latior, vix concavus ; tibize intermedi extus haud perspicue emarginate.

Includes C. axillaris, Germ., C. azurea, Serv., C. fulvocincta, Bates, C. xanthomera,

Redt., C. chrysomelina, Pascoe, C. criocerina, Bates, C. albicornis, n. sp., C. lycoides,

Bates, and C. ambigua, n. sp.

Mrimwotara.—Vertex inter antennas angustus, concavus (vel tubera antennifera alte elevata); tibiee intermedice

extus medio perspicue emarginate.

Includes C. halticoides, Bates, C. buckleyi, n. sp.*, and C. calopterona, n. sp.

All the species of the section ‘“‘Mimolaia” present mimetic resemblances to the

Lycide and other families; this, however, is not an exclusive feature of the section,

two species of Callia proper, viz. C. lycoides and C. ambigua, having a very similar

livery.

Of other species referred by authors to Callia, the following must be removed to

other genera:—C. lampyroides, Bates, to the allied genus Zenicomus, Thomson;

C. minuta (ante, p. 195) to Asemolea; and C. auricollis, Redt., to Hastatis.

3. Callia albicornis. (Tab. XXV. fig. 14.)

4. Callia ambigua.

Anguste oblonga, postice perparum dilatata, erecte setosa, nigra, cinereo-pubescens ; vertice thoraceque vitta

lata laterali aureo-tomentosis ; elytris vel toto nigris, vel vitta curta humerali (postice attenuata) fulva, vel

dimidio anteriori (sutura epipleurisque exceptis) fulvis; antennis articulis 3°-11™ basi anguste griseis ;

Hab. Panama, Bugaba (Champion).

The elytra in this species are relatively much longer than in the similarly-coloured

P. coccinea and P. lineola. From the other red species, P. miniata and P. rubella, it

differs inter alia in the colour of the antenne and legs.

Phza phthisica (p. 197).

Var. Antennis toto nigris ; macula nigra frontali medio divisa.

Hab. Mexico, Almolonga (Hége).

Phea phthisica is distinguished from P. macilenta and from P. tenuata by the upper

part of the forehead being black and the vertex clothed with golden pubescence, both

of which characters I omitted in describing the species. The variety above mentioned,

of which I have only seen a single specimen, differs from all the numerous examples

seen of P. phthisica by the black frontal patch being reduced in size and divided into

two spots.

9. Tetraopes 2

Hab. Mexico, Northern Sonora (Morrison).

One example of what is probably a variety of the North-American 7. femoratus, Lec.,

TETROPS (to follow the genus Tetraopes, p. 200).

Tetrops, Stephens, Man. Brit. Col. p. 269; Lacordaire, Gen. Col. ix. p. 880.

A genus charasteristic of North Temperate faunas both of the Eastern and the Western

Hab. Mexico, Mina de Zimapan (Baden, coll. Bates).

A very distinct species. The elytra are without trace of coste, and conspicuously

depressed for a broad space along the suture.

To the localities given, add :—Mexico, Jalapa (Hoge); Costa Rica, Volcan de Irazu

(Rogers).

ZERENICOPSIS (to follow the genus Antodice, p. 207).

Gen. Zrenice affinis et similis, sed differt oculis divisis, etc. Corpus elongatissimum, lineare. Caput parvum,

sphericum, antennis basi approximatis. Oculi divisi; lobis superioribus subsemicircularibus, medio vertici

sitis, parum distantibus ; lobis inferioribus maximis, intus (apud frontem) approximatis, extus late extensis.

Antenne filiformes, sparsim pilose; scapo elongato, cylindrico ; articulo 11° quam pracedens breviori.

Thorax cylindricus. Elytra linearia apice singulatim in spinam producta. Pedes breves, tenues, tibiis

intermediis extus medio emarginatis. Sterna et ungues sicut in renica.

The extraordinary Longicorn on which this genus is founded was taken by

Mr. Champion only in a single example. Judging from the antenne being scarcely so

long as the body, it appears to be a female. The two parts into which the eyes are

divided are quite different in position, relative size, and form from those exhibited in

Tetraopes and the rest of the numerous group of “Astatheini,” so that the genus cannot

be well included in that group.

One example only. The head and thorax are broader and more robust than in the

other species of the genus, but the long antennal scape and the pubescence of the joints

show that the species belongs to Hrana rather than to Cephalodina.

There is a male example in the Sallé collection, from Playa Vicente, evidently

belonging to this species rather than to EH. fimbriolata, judging from the red meta-

thoracic episterna; but it is remarkable for the absence of the black spots from the

thorax, of which, however, there are some faint traces of the hinder pair.

The pale yellow spots on the sides of the ventral segments are the same in number

in the sexes respectively as in Mexican typical examples, viz, in the ¢ two, in the ? four

(of which that on the first segment is very small).

Cirrhicera championi (p. 214).

The number of pale yellow spots on the sides of the ventral segments is stated in the

description to be five: this refers to the female only. In the male there is a small

rounded spot on each side of the first three segments only. This constitutes a good

character whereby to distinguish the species from C. salle and its varieties.

Numerous examples from the localities above named antl others received, during the

progress of the present work, from Costa Rica, show that A. druryi is not constant in its

distinctive marks from Amphionycha spectabilis (Drury). These marks (a broader black

basal, and a broader and more oblique white subapical, fascia) are pretty general in Costa-

Rican examples, but specimens occur in the same locality in which the marks are the same

as in Guatemalan specimens of A. spectabilis. In the Panama localities individuals occur

in which the black belts are covered with bluish-grey pile ; these approach A. bifasciata,

but differ from it in the form of the belts and other features. A. bifasciata remains a

tolerably distinct local form, peculiar to Chontales.

This species belongs but imperfectly to the genus Alampyris; the antenne are nearly

the same as in Amphionycha, and the elytra are striate-punctulate, and not irregularly

punctulate as in all known species of Alampyris. The incomplete lateral carina and.

the colours and facies decide me to place the species here rather than in Amphionycha.

however, there are always two white ventral segments in both sexes, and the hind

angles of the thorax are not so much prolonged. In the pale tawny-ochreous form of

The unique example which served for the original description was abraded in places,

hence no mention was made of the continuance of the black vitta of the crown down

the middle of the thorax, which is a conspicuous feature in well-preserved specimens.

The seven apical joints of the antennz are more or less pallid at the base.

The species varies in size from 34 to 6 lines.

Among the ten examples examined there is no trace of intermediate gradation between

the two distinct modes of elytral coloration above described. The form with black

apical half of the elytra resembles very much T. lycinella, but that species has the base

of the fourth antennal joint clothed with bushy pubescence like the whole of the third,

as in the majority of the Tyrinthic, and the lateral carina of the elytra (more obtuse

than in 7. diformis, and scarcely to be termed a carina) does not coalesce with the

lateral margin, but runs parallel to it.

Tribe BRUCHIDES*.

Fam. BRUCHID.

Tuis—one of the smaller of the families of Coleoptera—until comparatively recently

was placed in the Rhyncophorous series, and is included in Schénherr’s great work on

the genera and species of Curculionide. It has, however, become of late years generally

recognized that it cannot naturally occupy such a place, and it has consequently been

detached from its old association, but no position for it has been adopted with unanimity.

It is placed by Leconte and Horn, in the ‘Classification of the Coleoptera of North

America ’ (second edition, 1883), between the Chrysomelide and Tenebrionide. It would,

however, be certainly more naturally placed if it were made to precede, instead of follow,

the Chrysomelide (or Phytophaga), and in the present work it occupies such a position.

It may be well to mention that though, as a matter of convenience, it is included in

the same volume as the Longicornia, it is not to be inferred from this fact that there is

any special affinity between the two aggregates.

Our knowledge of the Bruchides is not sufficiently advanced to enable any trustworthy

generalizations to be made in reference to the species found in our region. Still

certain figures may possess some interest. Only two or three genera are yet recognized

in the family, and each of these has a very wide distribution. The total number of

species described before this work was commenced was about 570. The number of

recognized North-American species is about 50. The number here recorded as found

in our region is 150, but of this number eighteen have not been seen by the writer and

are more or less doubtful.

The members of this family have been unequally collected in different parts of our

region: Mr. Champion secured many species in Guatemala and in the State of Panama,

and the Mexican fauna is pretty well represented by the collections acquired from

M. Sallé and Herr Hoge; but, on the other hand, the Nicaraguan province is poorly

represented, and from Costa Rica we have received scarcely any Bruchides. The

South-American Bruchides are very inadequately known, so that little can be said as to

the geographical distribution of these insects. I may, however, remark that I am

acquainted with 51 Mexican species; that of this number seven occur also in the

- United States of North America, twenty-three + are found in Guatemala as well as in

Mexico, and eight extend at least as far south as the State of Panama. It would thus

appear that the Central-American region has but little in common with the United

States of North America, for at present there is actually a greater community between

+ In this computation the cosmopolitan species are not included.

438 | BRUCHIDES.

the extreme northern and southern points of our region, though so widely separated,

than there is between the Mexican province and the adjacent United States region.

This conclusion is, however, invalidated by two great facts: first, that the Bruchides

of the United States have not been thoroughly collated with those from our region

(owing to the very imperfect condition of collections of this family a great many of the

North-American species are quite unknown in Europe), so that there may be a greater

community than is yet ascertained ; second, that the borderland, where the greatest

community between the two regions will be undoubtedly found to exist, has been

inadequately explored.

After separating Caryoborus this genus will still comprise about 500 described

species, and is found in most parts of the World. The study of the insects of this

genus is at present a matter of great difficulty, no recent monographer having dealt

with it, and the arrangement suggested by Schénherr for the comparatively small

number of species known to him being eminently unsatisfactory. Indeed all the

structural characters appear to grade off again and again in the genus, so that no one

of them, as far as I have observed at present, can serve the purpose of dividing the

species even in a preliminary manner. The specific distinctions in fact frequently

consist of modifications of the very characters that have been used to define the groups

of species. Schénherr relied on the dilatation of the femora and on the shape of the

thorax, but each of these characters is among the most variable of the genus. Dr. Horn

has lately employed the denticulation of the hind femur with satisfactory results so far

as the North-American species are concerned ; but this will not help much as a means

of facilitating determination of the more numerous species found in our region. In

our species the normal denticulation of the femur in the genus appears to be one long

tooth and two small denticles, and this character occurs in several forms that in other

respects are very dissimilar; but, on the other hand, species that are very closely allied

differ in the number of denticles. The femoral denticulation, therefore, though of

great importance, can only be employed in subordination to other characters, and its

value in any case as a means of arrangement is largely discounted by the great number

of species that fall into the category of one tooth and two denticles; thus it happens

that Dr. Horn in arranging the North-American species into nine groups, has to place

half the species in one of these. I have, for the purpose of facilitating the labour of

BRUCHUS. 439

those who may have to use this work, adopted a number of groups of convenient size,

and sufficiently natural, for our fauna at any rate, to enable any one who has become

acquainted with a few species of each group to recognize, on a first inspection, with

tolerable certainty, to which group any other species should be referred. I cannot, how-

ever, disguise my knowledge of the fact that the determination from the description alone

of the numerous species I have characterized will be a difficult task, and that a certain

amount of reference to some of the types described will be almost indispensable.

The species previously described from our region are not numerous, and are due

chiefly to Schénherr, Say, and Motschoulsky. The species intended by this latter

author will, I think, in the majority of cases, never be recognized, owing to the peculiar

method he adopted in dealing with them. This consisted in characterizing in two or

three lines in a most insufficient manner certain groups, and then dividing and sub-

dividing these groups analytically. I have not been able to recognize any of the species

he dealt with in this way; but in the same paper he described some species in a more

ordinary manner, and about most of these I have been able to form an opinion.

It has of late been proposed to abandon, on the ground of priority, the generic name

of Bruchus, replacing it by that of Mylabris, which for about one hundred years has

been in use for a totally different genus of Coleoptera. The confusion introduced into

entomological literature by this proceeding is enormous, and as the proposed change

has no advantage other than its conformity with a theory of priority of generic names,

and as no inconvenience has been found to result from the nomenclature that has been

in use for a hundred years, I have not been able to adopt the change proposed. Owing

to the constant shifting and division of genera that naturalists require to make, no

absolute test of priority can be applied with advantage to long-established generic

names ; and it appears to me inadvisable to render this part of our Zoological literature

a mass of confusion because Des Gozis thinks Fabricius ought one hundred years ago

to have used Geoffroy’s name of Mylabris for this aggregate of species instead of the

Linnean name Bruchus. The name Andromisus, proposed by Des Gozis to replace

Pachymerus, is at present superfluous, as the group is incapable of definition in the

actual condition of our knowledge.

§ 1. Thorax conic, its sides concavely arcuate; hind femora largely dilated, armed

with teeth that in many species are numerous; antenne various in structure.

(Pacuymervs, Latr.)

Schénherr included in his Grex “‘Pachymeri” a “Stirps IT.” (possessing, however, only

a single species) for an insect with elongate and serrate antenne. I have thought it

better to place two analogous species in my group § 3. Even as I have limited it the

Group still remains a heterogeneous one, comprising a number of forms having little

relationship inter se. In our fauna the concavely-arcuate sides of the thorax is a

tolerably satisfactory character for the diagnosis of this group.

SoutH AMERIcA ! 2,

A small series of ten examples from our region exhibits much variation, but I am

unable to distinguish more than one species. The characters by which the species is best

distinguished from B. longicollis are the larger size, the greater amount of dark colour

on the elytra, the dark (nearly black) palpi and hind tibiz, and the existence ‘in the

males of a prominence above the middle of the pygidium limited below by a V-like

impression. In the example (a female) from San Feliz the size is not greater than

that of B. longicollis, and the palpi are pallid. The peculiarities of the male pygidium

show much difference in the extent of their development, and the colour of the hind

tibiz varies a good deal in its depth. Under these circumstances I conclude that

P. fuscicrus, Motsch., must probably be one of the smaller and more pallid varieties.

In this species the pygidium of the male does not exhibit any peculiarity, and the

palpi and hind tibie are usually pale yellow. The size varies greatly, and about half of

the examples from Bugaba are referable to a variety only half the size of the type ;

occasionally the palpi are more or less spotted with dark colour, and in the larger

individuals the hind tibie are castaneous-yellow; there is great variation in the

maculation of the upper and under surfaces. I think it probable that Motschoulsky’s

P. tuberculatus will prove to be one of the varieties of this species.

This insect is allied to B. longicollis—though very distinct even from the smallest

varieties of that species—by its smaller size, narrow elongate head with eyes farther

removed from the thorax; the armature of the femora is similar to that of the allied

species, viz. a long acute tooth near the apex, and almost or quite on the outer margin

of this tooth two or three other smaller denticles; these supernumerary denticles in the

present species are short and obtuse. The thorax has the sides a little concavely

arcuate, but the hind angles are only slightly acute, and the surface is free from

sulcation or tuberculation, the median longitudinal dark portion being only obscurely

elevated. The variegation of the elytra is slight and indefinite ; there is only a very faint

humeral elevation, and there are no callosities or depressions. ‘The pygidium and under

surface are so sparingly clothed that the ground-colour remains conspicuous. The

posterior tibiee are slightly arcuate at the base, and are armed at the extremity with a

very elongate, acuminate spine. There is a considerable difference (no doubt sexual)

in the structure of the antenne of the individuals of this species; these organs are in

some examples similar to those of B. brasiliensis, except that they are not so broad,

while in the other sex they are considerably longer, reaching back beyond the base of

the thorax, and with the penultimate joints each as long as broad. I am not able to

find any difference in the pygidium or ventral plates of these two forms, so do not know

which is the male.

Four examples were met with ; our figure represents an individual with the longer

antenne found at Bugaba.

Similar in form to Bruchus longicollis, but densely clothed above with pallid pubes-

cence, which is maculate only at the margins, and readily distinguished by the structure

of the head and breast. The former is elongate and narrow, but not to so great an

extent as in B. longicollis, and the constriction to form the neck is situated imme-

diately behind the eyes; the metasternum, though nearly perpendicular in front, does

not project as an angular prominence. The antenne reach as far back as the base of the

thorax, joints 6-10 being each broader than long. ‘The thorax is very narrow in front,

broad behind, the sides concavely curvate, the hind angles acute, the surface densely

clothed with pallid pubescence, which is more or less distinctly maculate with fuscous

and black spots. Elytra also densely clothed with pallid pubescence, concealing the strie,

A diagnosis /. c. is given without any comparative remarks, and no reference is made to

the structure of the antenne, or breast, or the armature of the femora; but asI am still

not able to find any species agreeing with the other characters given I must conclude

this is a species we have not received.

6. Bruchus cristicollis,

Convexus, elytris quadratis, supra variegatis; prothorace valde inwquali, medio inequaliter longitudinaliter

elevato, elevatione sulcata; pygidio densius longiusque pallide ochraceo-vestito, apicem versus trinoduloso ;

femoribus posterioribus subtus ultra medium dente longiore armato, et ad apicem dentibus plurimis

irregularibus.

Long. 4 millim. (capite deflexo).

Hab. Mexico, Yolos (Sailé).

This is of about the size and form of B. longicollis, but is not closely allied to that

species nor to any other known to me. Only a single example has been received, and

from this I judge that the species will be readily recognized by the very uneven surface of

the thorax, and from the fact that the pubescence of the upper surface is not so short as

usual, and thus the maculations on the elytra are many of them slightly raised patches.

The head is evidently rostrate, but rather broad ; the eyes moderately prominent, widely

separated in front. The thorax is very narrow in front, the sides arcuately concave,

the hind angles very acute, the surface with two irregular ridges along the middle; these

ridges rise behind so as to form a considerable prominence a little distance in front of

the scutellum, and between their highest point and the scutellum are clothed with more

pallid pubescence, like that on the scutellum; on either side in front of the base there

isa small but rather elevated prominence. The elytra are of a dark vinous-fuscous colour,

and bear geminate series of quite distinct punctures, and are spotted with slightly raised

patches of griseous and nearly black pubescence. The anterior legs are red; the posterior

legs and the greater part of the under surface, black. the sculpture not so fine as usual ; the

hind tarsi red. The metasternum is nearly flat, obliquely declivous in the middle in

front. The armature of the hind femur differs from what obtains in B. longicollis,

inasmuch as the smaller teeth are quite separated from the anterior one; they are

irregular in size and four or five in number, rather crowded together, the outer of

them minute.

Hab. GuateMaALa, Paso Antonio 400 feet (Champion).

Of this species only a single example was obtained, pretty certainly a female; though

apparently allied to B. boops, it possesses some important distinctions. The head is

broad and short, the eyes only slightly prominent, finely granulate. The thorax has

the sides arcuately concave, the hind angles acute, the base strongly lobed in the

middle, the surface slightly uneven, without any peculiarity in front of the scutellum.

The four anterior legs are yellow. The hind femur bears a sort of elevated lamina on

the lower half, the lower margin of which is pectinate, the teeth being thirteen in

number, the inner one twice as long as any of the others. The metasternum is nearly

flat, without angular prominence or declivous front portion.

Hab. Guatemaua, Mirandilla (Champion); Panama, David, Volcan de Chiriqui 4000

This elegant little insect differs from the true Pachymeri in the structure of the

antenne, which in the female have the penultimate joints a good deal produced in

front, while in the male they are strongly pectinate; the peculiar angular white mark

in front of the scutellum encloses a small depression; the middle of the breast is

rather convex, but not in the least angular, and the apex of the mesosternum between.

the front coxee descends to the lower part of the breast. The structure of the hind

femora is a considerable approximation to that of the genus Caryoborus, but the pro~

thorax is extremely different from that of Caryoborus, and is of the normal Pachymerus

type.

Four examples were met with ; the elytra of the one found at David are not nigrescent

behind.

Hab. Panama, Bugaba (Champion).

Only a single example of this graceful insect was obtained, and no doubt it is a male.

It is allied in many respects to B. juno, but the armature of the femora is intermediate

between that of the species just mentioned and that of B. brasiliensis; the four teeth

joined to the larger one are each shorter than its predecessor, the first of them evidently

springing from the long tooth. The rest of the structure seems very similar to that of

B. boops.

Long. 3 millim. (capite deflexo).

Hab. Panama, Caldera in Chiriqui 1200 feet, Tolé (Champion).

This species is allied to B. albotectus, but is not half the size of the smallest examples

of that species, and the metasternum is more rounded and gently declivous in front.

-The thorax is very narrow in front, with the sides concavely arcuate and the hind angles

acute, a little raised longitudinally along the middle, and a little depressed on each side

the middle near the base so as to cause a not very well-marked callosity on each side ;

it is densely clothed with pallid griseous pubescence and only very obscurely maculate.

The elytra are very finely striate, the striation being concealed by the very dense pallid

pubescence, which is maculate only at the shoulders and at the sides a little behind the

middle; they are without depressions or elevations. The pygidium is densely clothed

with pale tomentum, and not distinctly maculate. The under surface is blackish, clothed

rather closely with pallid pile. The antenne have the joints 6-11 each broader than

long. The hind femora are strongly arched above, little inflated beneath, armed near the

extremity with a long acute tooth, and with three smaller teeth forming an extension

backwards of its posterior margin, much as in B. longicollis and the allies; the tibial

spur is elongate, quite as long as the entire breadth of the tibie at its extremity.

I do not observe any sexual differences among the four examples that were obtained

of this species.

Long. 22 millim. (capite deflexo).

Hab. Guaremata, Zapote, San Gerdénimo (Champion); Panama, Bugaba, Volcan de

Antenne short and broad; joints 6-11 each broader than long, dark in colour, the

terminal joint not paler. Thorax very narrow in front, with concavely arcuate sides

and acute hind angles, at the base with a depression on each side of the scutellar lobe.

Elytra feebly striate, densely covered with pubescence, which is principally pallid, but

is broken up at the sides by rather indefinite darker spots. Pygidium narrow, very

elongate, clothed with pale pubescence, and indistinctly striped with still paler pubes-

cence. Legs much clothed with pubescence ; spur of the posterior tibia short and stout.

Though bearing a considerable resemblance to B. calderensis this species is really

very distinct by the short apical tibial spur and the different position of the minor teeth

of the femur.

Only one example was found at each of the localities mentioned.

Long. 3} millim. (capite deflexo).

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

Although very dissimilar in colour to B. confinis this species is closely allied thereto,

but has the femora rather differently armed and the surface of the thorax and elytra

less even. The thorax is distinctly elevated along the middle, and has a callosity on

either side, near which a few coarser punctures may be distinguished, though much

concealed by the vestiture; the scutellum is clothed with pale pile, and there is a

minute spot of similar colour on the base of the thorax in front of this; the coloration

of the thorax is chiefly dark, but there are on it several irregular paler marks. The

prevalent colour of the elytra is dark, but they are obscurely lineate on the alternate

interstices with fuscous colour; this is distinct near the suture, but elsewhere indistinct,

and there are also small indefinite flecks of white colour; there is a slight callosity .

between the shoulder and the scutellum, and the surface is also rendered uneven by

some obscure depressions; the pygidium is densely clothed with pallid pubescence,

which is subvariegate. The hind legs are dark, the femora variegate with pubescence ;

the four smaller denticles of the femora all distinct from the longer tooth; the apical

spur of the tibice rather short. |

Six examples were met with; five of these were found on the Volcan de Chiriqui,

only one or two specimens at a time.

Long. 3 millim. (capite deflexo).

Hab. Mexico, Jalapa (Hoge).

In this species the antenne are more slender outwardly, and subserrate, the penul-

timate joints being scarcely shorter than broad. The thorax has no inequalities, but

its sculpture can be distinguished through the vestiture. ‘The elytra are chiefly black

with indistinct red patches, the ground-colours being, however, concealed. by the pubes-

cence; they bear numerous series of coarse punctures, three or four of these series

between the shoulder and scutellum terminating in a slightly arcuate or angular elevation ;

the maculation is indefinite. The pygidium is narrow and very elongate, densely clothed

with pale pile, subvariegate. The lower half of the hind femur is black, the upper part

red; the six supernumerary teeth form a curvate prominence. The metasternum is not

declivous in front; the tibial spur moderately long.

Three examples have been received of this species.

Hab. Fere in ogpe toto; NortH AMERIcA’.—PaNaMA, Bugaba, Volcan de Chiriqui

The position of this species should for present convenience be among the smaller

Pachymeri, the penultimate ventral plates being very abbreviate and the femora

sufficiently dilated; the structure of the femur is, however, very different from any

other of the group, and the concave arcuation of the sides of the thorax very slight.

It is recorded in the Munich Catalogue, x. p. 3222, as a synonym of Bruchus chinensis,

Linn. & Thunb.; but this is apparently erroneous, as also is the fact that in the same

work the only record given for B. scutellaris, Fabr. & Gyll., is “ Cap. bon. spei.” On

reference to the works in question it will be found that Fabricius gives no locality, and

that Gyllenhal’ says, “habitat in seminibus utriusque Indie, etiam ad Caput bon.

spei et in Brasilia.” In settling the synonymy of this species we are thus deprived of

the assistance usually derived from the citation of a limited “habitat.” Only two

examples from our region have reached me.

Hab. Guatemata, Capetillo (Champion),

Head broad, evidently rostrate; eyes prominent. Antenne a good deal longer than

the head and thorax; second joint very small in comparison with the third. Thorax very

narrow in front, the sides feebly concavely arcuate, the hind angles very acute, the posterior

portion more elevated than the anterior ; clothed with pubescence chiefly of a griseous

colour, with a curved series of six indefinite black spots across the middle; numerous

coarse punctures are visible through the clothing. Elytra marked with fuscous and

black, with a white spot on each close to the middle of the suture, and also with a few

small white flecks. Pygidium and ventral plates densely clothed with white pubes-

cence. Hind femora thickly clothed with pallid griseous pubescence.

This species is not allied to any other found in our region, but may be placed in

Stirps II of Schénherr’s Grex II. The metasternum is flat; the femoral armature

consists of a raised ridge armed with about eight teeth, the anterior tooth of the series

being broken off in the example obtained ; the apical ventral plates are evidently only

extremely abbreviate in the middle.

Hab. GuateMata, Rio Maria Linda 500 feet (Champion).

The eyes are quite finely granulate, not very prominent, widely separated ; beak very

short. Antenne with four basal joints slender, the others broad. Thorax very narrow

in front, the sides concavely arcuate, the surface even, covered with a pale griseous

pubescence, which allows the numerous deep ptinctures to be seen. Elytra finely striate,

covered with slightly variegate pubescence in colour like that of the thorax, but here

and there rather darker, and paler, and interrupted by rather more distinct oblong

darker spots. Pygidium pubescent like the thorax, distinctly punctate. Hind femora

armed with a long pointed tooth, and close to it, the anterior in fact on it, with three

smaller but very distinct teeth. Hind tibie moderately curvate, armed with long apical

spur. Terminal ventral plate emarginate in the middle and subtuberculate on either

side of the emargination.

This is a most anomalous species, the thorax and hind legs having the structure of

the Pachymerus group, but the construction of the hind body is quite different and

nearer to B. humeralis and its allies. Unfortunately only one example was met with.

Hab. Panama, David, Bugaba, Taboga Island (Champion).

This is a very peculiar species, apparently not nearly allied to any known form. The

very broad antenne, the strongly and regularly arcuate tibie, and the remarkable

adornment of the pygidium make it easily recognized. The head is somewhat narrow

and rostrate, but much less so than in B. brasiliensis. The thorax is very narrow

in front, much broader behind, with the sides concavely arcuate and the hind angles

acute, the base strongly lobed in the middle. The elytra are finely punctate-striate.

The pygidium is finely pubescent and dull at the base, but beyond this is shining and

sparingly punctate, and adorned with a narrow mark of very dense white pubescence,

which in the female forms an oval spot separated by about its own length from the

hind margin, but in the male is more elongate so as to reach the extremity.

A series of fourteen examples was obtained showing considerable variation in size and

in the depth of the ground-colour, which is sometimes nearly black, sometimes of a dark

vinous-red tinge. The example figured is a female from David.

The antenne and general form suggest that this should belong to the subgenus

Pachymerus, but the different armature of the femora, and the fact that the meta-

sternum is not perpendicular in front will necessitate the isolation of the species in a

separate subgenus or genus.

§ 2. Thorax conic, its sides either not curvate, or slightly convexly arcuate ; hind femora

only moderately dilated, armed with a tooth and one, two, or three denticles ;

antenne rather short, simple, only subserrate ; ventral rings never elongate, the

penultimate three usually very short ; pygidium usually perpendicular.

This group, so far as our species are concerned, is homogeneous, but it is approximated.

transverse. Head short, eyes moderately separated. Thorax elongate, very narrow in

front, the sides slightly concavely oblique, the surface densely covered with pubescence

concealing the coarse punctuation, the pubescence chiefly flavo-griseous, but with nearly

black marks on the front and middle, and an elongate triangular white mark at the

base. Scutellum clothed with white pubescence. LElytra finely but deeply striated,

variegate with the same colours as the thorax arranged transversely but irregularly,

and the white markings consisting only of a few small isolated spots. Pygidium clothed

densely with flavo-griseous pubescence, but with an elongate very conspicuous white

mark at the base in the middle, and on either side of its apex a black spot. Under

surface variegate with black, white, and yellowish-grey.

B. mundulus differs in several important particulars from B. pictifemur, the species to

which it is most similar in facies—the apical ventral plate being very short, and in the

middle very reduced by the incurvation of the apex of the pygidium, the armature of the

femora consisting of a small tooth and two scarcely perceptible denticles near it, and

the apical spur of the tibie being very short, though slender and definite. Only one

example is known to me.

like the thorax, but at the extremity with a common, conspicuous large cordate mark.

Pygidium clothed rather densely with nearly white pubescence. Spur of hind tibia

quite short.

Only a single example of this minute species was obtained. The penultimate ventral

rings being very short and the hind legs incrassate would place it in Schénherr’s Pachy-

meri, it being in the structure of the antennee intermediate between his Stirps I and II.

ventral segments it accords with the small species of the Pachymerus group, while by

its other characters it might be placed in Schénherr’s Manipulus I of Grex I. The

three basal joints of the antenne are small and red in colour, the other joints being

much larger ; joints 6-10 each broader than long, red, but clothed with a dark fuscous

pile. The thorax is transversely conic, the sides oblique, not concave; surface quite

even, red in colour, near each side with a very fine line formed by three connected, very

slender gutte, and there is also a very minute pallid spot in front of the scutellum. The

elytra are red, and have across the middle a very slender angulate white band; this

band is connected on each wing-case with a few minute transverse pallid spots near the

outside, so that the band appears furcate on each elytron. The posterior femora are

armed with one rather short tooth; the tibie are rather short and stout, curved only

slightly at the knee, and with a short apical spur; basal joint of hind tarsus very long.

fascia at the extreme base, including the scutellum, white; a short sutural mark

extending backwards from this of the same colour, as also an irregular transverse fascia

in front of the middle; apical half pallid ashen like the thorax; striation fine but

distinct. Pygidium and ventral plates densely clothed with pallid ashen pile ; hind coxe

black, the breast white. Hind femora with a long, slender tooth, and behind it and

quite separated from it a much shorter tooth emarginate or bifid at the summit. Hind

tibie short, strongly curvate at base, stout, with rather short apical spur; basal joint

of hind tarsus stout.

This is another of the species forming a transition from the “ Pachymeri” to the

Stirps I of “ Bruchi genuini.” The penultimate ventral plates though not so abbreviate

as in most of the Pachymeri are still of the same type. A single exponent was found

in each locality.

Long. 13 millim.

Hab. Guaremata, San Gerdénimo (Champion); Nicaraava (Sallé).

Head very short, eyes very widely separated. Antenne reaching nearly as far back as.

the base of the thorax ; third and fourth joints rather small, subequal, fifth and following

joints infuscate or nearly black, penultimate joints not quite so long as broad. Thorax

with a distinct coarse punctuation, and clothed with a very pallid ochreous pubescence.

Elytra finely striate, of a pallid red colour, more or less marked with black or fuscous.

along the suture and outer margin, their pubescence similar to that of the thorax.

Hind femora bearing only a quite small tooth and two minute acute denticles quite

near to it; tibiee with a delicate rather long spur. The male has the hind body entirely

black and the pygidium more inflexed at the apex, so that the apical ventral plate is

very short in the middle; in the female the four terminal ventral rings and the pygidium

are red, and the last ventral ring, though quite short, is not any shorter in the middle.

In each sex the three last ventral rings are quite short, but are a little shorter in the

male than they are in the female. :

. The small size of the femoral teeth is one of the more important of the diagnostic

characters of this species, which, perhaps, would be better placed among the small

insects forming my Group § 6. |

So far as I can judge from the small series of eight examples, the coloration of the

under surface is pretty constant in each sex ; the upper surface, however, varies a good

deal in colour, and the thorax, which is usually rufescent, may be black. From Nicaragua

only one example has been obtained.

Parvus, niger, pallide ochraceo-vestitus; antennarum basi, pedibus elytrisque rufis, his sutura margineque

Long. 2 millim.

Hab. Guatumata, San Gerénimo (Champion).

This species is extremely similar to the larger and darker individuals of B. ruficoxis,

but differs as follows: it is of superior size, with less abbreviate ventral rings, dark coxe,

and a rather larger tooth followed by three denticles on the hind femora. The male

has the antenne evidently longer than they are in the female, with a very much larger

fourth joint. The spur of the hind tibia is of moderate length and slender, similar to

that of B. ruficovis. Only three examples are before me.

25. Bruchus argutus.

Parvus, niger, ochraceo-vestitus ; elytris rufis, sutura margineque exteriore argute nigro-maculatis; antennis

posterioribus dente parvo denticulisque duobus instructis; tibiis posterioribus apice longius calcarato.

Long. 24 millim.

Hab. Mexico, Jalapa (Hége); Guatemata, San Gerénimo, Duefias, Chiacam, Zapote

(Champion).

This species is excessively similar to B. ruficoxis and B. difficilis, but is undoubtedly

distinct ; compared with the former it is found to be larger, with the hind femora and

the coxee dark, the armature of the femora less minute, and a much longer spur on the

hind tibia; this last character is diagnostic of this species amongst the immediate

allies. The antenne are quite short, with the penultimate joints evidently transverse

and the fourth joint not larger than the third. Four typical examples have been

received, and if,as I presume, from a minute difference in the ventral rings, I have both

sexes before me, then the sexual characters are very slight. The ventral rings are less

abbreviate than they are in B. rujficoxis.

The examples from Jalapa, Zapote, and Duefias are in each case unique, and are

referred to this species because I see no good structural characters to separate them,

but it is quite possible they represent three other very closely allied species. |

26. Bruchus argillaceus.

Parvus, niger, minus tenuiter ochraceo-vestitus; pedibus rufis, pygidio rufescente; antennis fusco-rufis, basi

Long. 23 millim.

Hab. Guatemaa, Duefias, Capetillo (Champion).

This is an obscure insect allied to B. obsoletus, Say, but smaller, with the pubescence

BRUCHUS. 4538

of the surface uniform, and the second joint of the antenne smaller, so that there is a

conspicuous difference between it and the third joint. The mucro at the extremity of

the hind tibia is very short, as in B. obsoletus. It is equally similar to B. difficilis, but

that species has the third joint of the antenne small, and three distinct denticles on the

hind femur. Only four very fragmentary examples are before me, but from these it is

clear that the colour of the surface is variable; when there is a vitta of red colour on

the elytra the resemblance to B. difficilis is considerably increased. I am not able to

detect any sexual characters.

27. Bruchus pruininus.

? Bruchus pruininus, Horn, Trans. Am. Ent. Soc. iv. (1878), p. 3277.

Hab. Norta America, Arizona 1—Mexico, Guanajuato (Sal/é).

I refer a single mutilated example to this species with some doubt. It presents no

salient points of distinction when compared with Horn’s description 1, except that it is

apparently less densely clothed with pubescence. It is exactly similar in appearance to

B. vexatus, but the thorax is shorter, the two basal spots are not present on it, the

hind femur bears two denticles in addition to the tooth, and there is apparently no

mucro to the tibia. This last point is not quite clear, as the hind legs are much

mutilated.

28. Bruchus vexatus.

Long. 23 millim.

Hab. Mexico, Toxpam (Salle).

Head short and broad, eyes widely separated. Antenne short, the basal joints infus-

_-eate yellow ; third joint a good deal longer than the second or the fourth, penultimate

joints strongly transverse. Thorax rather elongate, very coarsely punctate, clothed

sparingly with white pubescence, which is concentrated at the base on each side to form

a small spot; scutellum densely clothed with white pubescence. LHlytra rather elongate,

somewhat deeply striate ; black, sparingly but uniformly clothed with very fine white

pubescence ; interstices not sculptured. Under surface rather more closely and less uni-

formly clothed with white pubescence ; hind coxe quite bare. Pygidium rather small.

Hind femora short, somewhat incrassate, armed with a single rather large tooth; tibia

short and stout, slightly curved at the base, armed at the extremity with a rather short

mucro.

Long. 27 millim.

Hab. Mexico, Guanajuato (Sallé).

Four basal joints of the antenne sordid yellow; fourth small, the penultimate joints

rather strongly transverse. Thorax much narrowed from the base to the front, and only

slightly rounded near the front angles; very coarsely punctate, the punctuation visible

notwithstanding the variegate pubescence ; this is of a grey colour, denser about the sides

on the basal lobe, and a very narrow line along the middle. Elytra variegate with two

shades of grey leaving black spots, the most conspicuous of which is a very large one

on each side. Pygidium grey; under surface pallid grey, the pubescence condensed

on the pleure, so that this part of the sides is white. Hind tibia armed with a long,

slender mucro.

This is very similar to B. pullatus in Group § 6, but the unique example is twice the

size of any individual I have seen of that species, and has a more conical thorax.

30. Bruchus ornatus.

Supra pallide rufus, densius pallide griseo-vestitus, fusco-maculatus; subtus niger, abdominis apice rufo ;

antennis brevibus pedibusque testaceis ; femoribus posterioribus nigro-plagiatis, dente gracili denticulisque

Long. 23 millim.

Hab. Mexico, Guanajuato (Sallé).

Antenne short and stout, pale yellow. Thorax densely clothed with pallid subvariegate

pubescence which is thickest and more pallid in front of the scutellum. Elytra marked

with numerous small dark spots, and with a pubescence of a griseous and ochraceous

colour. The hind tibia is without mucro at the extremity, there being only a slight

prolongation of the anterior angle.

Although the legs differ little from those of B. argillaceus, yet the broader and shorter

pallid antenne and the coloration are so different that I cannot place this as a variety

of B. argillaceus. A single example is all that is known. In coloration it resembles

B. debilicornis of Group §1. &%

One example only.

Horn’s B. limbatus, and supposed to have been examined by Horn, does not agree with

Long. 23 millim.

Hab. Guatemaa, San Joaquin in Vera Paz (Champion).

Another species represented by a single example, very similar to B. placidus, but with

a rather long apical spur to the hind tibia, this latter only very slightly curvate at the

base, and the femora not so dilated; the antenne, too, are longer ; the under surface is

entirely red, the breast not being black in the middle, as it isin B. placidus. The

head, like the rest of the surface, is red, rather longer in front than it is in the

allied species; the antenne are stout, a little serrate internally, with the penultimate

joints strongly transverse, the terminal joint rather paler than those preceding it. The

upper surface has no appearance of maculation either of the ground-colour or

pubescence.

34. Bruchus submuticus.

Parvus, rufus, ochraceo-vestitus, vix submaculatus ; sutura angustissime nigra, pectore medio nigricante ; antennis

brevibus, testaceis ; femoribus posterioribus dente minuto denticulisque tribus minutissimis armatis.

Long. 27 millim.

‘Hab. Mexico, Northern Sonora (Morrison).

This insect is very similar to B. placidus, and, like it, has the surface of a nearly uni-

form dilute red colour. 3B. submuticus is, however, smaller, and is entirely distinct by

the extreme minuteness of the armature of the hind femora, in which respect it rather

resembles B. ruficovis. The upper surface of the head is black; the third joint of the

antennz only slightly longer than the second, the penultimate joints strongly transverse.

The thorax is transversely conical ; the spur of the hind tibia slender and moderately

long, rather longer and more slender than that of B. placidus. In the male the last —

ventral ring is deeply emarginate in the middle, in the female only very slightly.

The series of twelve examples we have received exhibit very little variation, except

that the pubescence in very fresh examples is white, especially beneath, and the faint

maculation of the elytra is in these examples more distinct.

35. Bruchus limpidus.

Parvus, rufus, ochraceo-vestitus, vix submaculatus ; antennis brevibus, latis, testaceis ; pectore medio nigricante ;

femoribus posterioribus dente acuto denticulisque duobus armatis.

Long. 24 millim.

Hab. Guaremata, near the city, Capetillo, Zapote, Duefias (Champion).

This species is extremely similar to B. placidus, but the examples are smaller, and

have only two denticles on the hind femur, and the apical spur of the hind tibia is quite

short. Tbe dark colour on the under surface spreads to a greater or less extent over the

ventral rings. The structure of the hind legs readily distinguishes tHe species from

B. submuticus, to which, in respect of form, size, and colour, it is extremely similar.

The South-American B. paleatus, Jekel, is probably another closely allied species, but

the details of structure of the hind legs are not given in the description of the French

author; and it may be presumed that the two are different. In the male of B. limpidus

the terminal ventral ring is excised in the middle almost as far as the margin of the pre-

ceding ring.

We have received a series of sixteen examples of the species.

36. Bruchus solitarius.

Niger, supra fusco-rufus, ochraceo-vestitus, submaculatus ; antennis brevibus, latis, pedibusque testaceis ; femo-

ribus posterioribus dente elongato denticuloque prominulo armatis.

Long. 22 millim.

Hab. GuaTEMAaLa, near the city, Zapote (Champion).

Although we have only a single typical example of this species, and it is undoubtedly

very close to B. limpidus, yet it appears to me to be probably distinct, as it is rather

broader and of darker colour, with more elongate tooth on the hind femur, and the two

smaller teeth replaced by a single prominent one. The spur of the hind tibia is.

reduced to a mere angular prominence. ‘The pygidium is densely clothed with

ochraceous pubescence. |

A second example, in very fragmentary condition, found near the city of Guatemala,

is not larger than B. limpidus, and has the sides of the elytra broadly marked with

dark colour; as the armature of the legs agrees, it is at present presumed, and I think

may really prove, to be the same species. It should be remarked that the denticle of

the femur in B. solitarius is a little emarginate at the apex, giving somewhat the

appearance of being formed of two denticles crowded together.

37. Bruchus elevatus.

Brevis, convexus, niger; subtus pallide griseo-vestitus ; prothorace utrinque ochraceo-vestito ; elytris tenuiter:

rioribus dente mediocri denticulisque duobus minutis instructis.

Long. 2? millim.

Hab. Guatemata, Cahabon (Champion) ; Panama, Bugaba (Champion).

BRUCHUS. 457

About the size of B. placidus, but shorter and more convex, and distinguishable by

the scanty clothing of the elytra, which consists of nearly white pubescence, forming

very slender, extremely indistinct, white longitudinal lines on the black ground, and

between these lines two transverse series of equally faint white flecks across the middle.

The second, third, and fourth joints of the antenne differ but little in their lengths,

and the penultimate joints are strongly transverse. The hind tibie are armed at the

extremity with a rather short spur, not quite so long as the width of the apex of the

tibia. Only one example was met with in each locality. The black ground-colour in

this insect is feebly diluted with red, and this slight reddening is more conspicuous in

the example from Guatemala than in the Bugaba exponent.

38. Bruchus crassulus.

Brevis, convexus, niger, subtus pallide griseo-vestitus, supra pallide subvariegatus; antennis brevibus, crassis,.

armatis.

Long. 3 millim.

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

This species is readily distinguished by the single tooth of the femur, there being on

its hind margin only a faint indication of one additional denticle ; the femur is not much

dilated, and the thick tibia is scarcely at all curved, and there is a short but quite defi-

nite mucro at its extremity. So far as I can judge by a single individual, there is no

distinct pattern on the upper surface, which, however, is much flecked in an irregular

manner with white, and the black ground-colour is indefinitely spotted with red. The

antenne are coloured in a similar manner to those of B. obsoletus, but are considerably

shorter; the general shape is shorter and more convex than in B. obsoletus, and the

pygidium is longer and narrower.

This is another species represented only by a single example. It has much the

appearance of B. incensus and B. pictifemur, but is distinguished from them by the

form of the thorax, which is not so elongate and has not concavely-arcuate sides.

The head is very short, the eyes widely separate, the vertex not carinate. The thorax

is rather short, much narrowed to the front, coarsely punctate, minutely speckled with

ochreous pubescence, on the middle with two distant, very minute, white specks.

Elytra rather elongate, finely striate, minutely speckled with ochraceous and pallid grey.

Hab. Panama, Volcan de Chiriqui below 4000 feet, Bugaba, Los Remedios

Antenne rather short and slender, the four basal joints yellow, the others dark;

second, third, and fourth joints subequal in length, penultimate joint slightly transverse.

Elytra of a tawny colour differing little from that of the rest of the upper surface, but

submaculate with patches of more pallid pubescence, and also with a few oblong patches

of a darker tawny or fuscous colour. .

This species cannot be treated as a small variety of B. obsoletus on account of the

elongate mucro of the hind tibia. Its structural characters are almost the same as

those of B. argutus, but the very different coloration leaves little doubt the two are

distinct. Four examples are referred by me to this species; one of the two from the

Volcan de Chiriqui is of broader form, with shorter, entirely testaceous, antenne.

This insect is said to be very abundant and destructive in the United States17, but

not to be very variable. I have no evidence of its being abundant in our region, but it

exhibits considerable variation therein. The synonym of B. pallidipes is given on the

authority of Jekel*, and it is quite probable that some of the other descriptions in

Schonherr’s work (B. tetricus and B. ventralis, e. g.) may prove to refer to the same

species. I have adopted the name used by Horn, though B. obtectus, of the same date,

is better known in Europe. In the Munich Catalogue B. obtectus is said to be the

same as B. mimosw, Fabr. & Oliv., but this appears to me excessively doubtful.

margin, the tooth not much more prominent than the first of the denticles; the tibia

is short, but little curvate, furnished at the apex with only a slight prolongation of its

anterior angle, not long enough to be called a mucro. In the female the last ventral

ring is twice as long as that preceding it, while in the male it is only of the same

length.

Eyes very deeply emarginate, little separated; vertex carinate. Thorax very narrow in

front ; its surface uneven in consequence of a transverse depression in front of the middle,

and a slight convexity of the basal portion, very densely and indistinctly, though not very

finely, sculptured ; very sparsely clothed on each side with white. Scutellum minute,

white. Elytra finely but deeply striate just before the middle, with an irregular, very

faint, milky-white band, and in front of this a depression. Pygidium only mode-

rately large, very finely sculptured, and bearing a white, very delicate, clothing, not

concealing the ground-colour. Front and middle tarsi and apices of the tibiz yellow;

hind tarsi yellow, with the basal joint black, except at its extremity. Femora moderately

dilated ; tibiee arcuate at the base, unarmed at the extremity.

This is a very distinct species, but is undoubtedly allied to the following, B. cyani-

pennis. Both species have a similarity in form to the European B. canus, but the apical

ventral rings are considerably shorter in the New-World species. Only three examples

were found of B. ptinoides.

This species has greatly the aspect of the European B. canus, Germ., which, however,

has unarmed tibie. It is closely allied to B. ptinoides, but differs not only by the even

surface and the blue elytra, but also by the fact that the hind tibie are armed with a

short spur. I presume that the front tarsi being obscurely flavescent is a mark of the

male sex.

Eight examples were brought back from Guatemala and two from the Volcan de

the examples from Guatemala.

the elytra, though very distinct and regular, are fine, and not punctate. The white

pubescence on this insect is very minute and scanty, except on the parapleure and the

scutellum, where it is more condensed.

Only a single example has been received of this species, which has the aspect of a

minute B. canus, Germ., and would appear to be closely allied to B. cyanipennis,

except that the larger tooth on the hind femur is absent; possibly this may be the

result of accident, but I do not think such is the case. The hind tibiz have no spur.

47. Bruchus modestus.

Niger, subtilissime albido-canescens ; antennis (femine ?) intus subserratis, articulis secundo tertioque minutis,

subtus testaceis; oculis sat magnis, minus approximatis; prothorace conico, densissime et subtilissime

sculpturato, opaco; elytris subtiliter striatis; tibiis anterioribus flavis; femoribus posterioribus dente sat

elongato denticulisque duobus armatis. .

Long. 2 millim. (capite deflexo),

_ Hab. Guatemata, San Gerdénimo (Champion).

Head with very short muzzle, eyes rather widely separated, vertex not carinate; legs

rather slender, hind femora not much swollen.

Notwithstanding the great resemblance in colour, form, clothing, and sculpture

between this species and B. serraticulus, the structural differences separate the two

completely. Only one example of B. modestus has been met with; it is, I fancy, a

female, and, if so, the male will probably have the antenne more strongly serrate.

48. Bruchus multisignatus.

Niger, tenuiter albido-vestitus; antennarum basi, tibiis, tarsisque anterioribus, testaceis; elytris guttulis elongatis

numerosis fascias transversas irregulares formantibus albidis; antennis maris elongatis, subpectinatis,

femine sat elongatis, serratis; femoribus posterioribus dente elongato denticulisque duobus armatis.

Hab. Guatremata, San Gerénimo (Champion).

Antenne with the three basal joints dull yellow; second joint small, the third elongate.

Head with prominent, coarsely facetted eyes, which are but little separated in front;

vertex carinate. Thorax regularly conical, black, lightly sprinkled with white pubes-

cence, its sculpture rather coarse and distinct. Hlytra black, with a small but

conspicuous white mark on the suture behind the scutellum, and with numerous other

white marks, forming two irregular bands across the middle; finely but distinctly

striate, the strie finely punctured. The hind femora are moderately dilated, the tibie

armed with a rather long apical spur. Besides the difference in the antenne of the

sexes, the male appears to be rather larger than the female, and has the terminal

ventral ring shorter in the middle.

Two males and one female have been procured. The species is allied to B. cyani-

Long. 23 millim. (capite deflexo).

Hab. GuaTEMALA, near the city, Aceituno, San Gerénimo (Champion).

Antenne very pallid ; second joint small, the third elongate, the terminal joints rather.

longer than broad. Eyes very large, with facets of moderate size, separated on the vertex

only by the longitudinal carina. Thorax narrow in front, with acute hind angles,

densely pubescent, scarcely variegate. Elytra very finely striate; densely clothed, the pale

clothing more or less distinctly interrupted by fuscous marks, the largest and darkest

of which are at the suture, behind the scutellum, and close to the extremity. The

posterior femora are much dilated, and armed with a single small tooth, behind which

are one or two extremely minute tubercles; the short, stout tibie are a good deal curved

at the base and at the apex, they have no apical spur, but the acute angle is very

slightly prolonged.

Although the pygidium is not so elongate or vertical as in most other of the

Pachymeri, this species might be placed in Stirps IL of Schénherr’s Grex II. One

example was obtained at San Gerdénimo, and a second near the city of Guatemala;

these I have no doubt are both males, and are described above. The specimen found at

Aceituno is, I feel certain, the female of B. ophthalmicus, though it has the eyes very

much smaller and more distant, and the antennz less developed, being more slender

and much shorter.

50. Bruchus debilicornis.

Ferrugineus, supra dense ochraceo-vestitus; elytris fusco albidoque variegatis, antennis pedibusque pallide

testaceis; subtus tenuiter griseo-vestitus, prosterno pectoreque nigricantibus ; antennis elongatis, graci-

libus, intus subserratis; oculis magnis, parum distantibus; femoribus posterioribus dente minore denti-

culisque duobus armatis.

Hab. Guatemata, Capetillo (Champion).

This is closely allied to B. ophthalmicus, but, compared with the male of that

species, is smaller, has the antennz more slender, the eyes not quite so approximate,

the maculation of the upper surface greater; the tubercles at the extremity of the hind

femur are also more prominent so as to form two minute teeth. Only one example has.

Hab. Panama, Aspinwall}.

We have not received anything agreeing with this description, and the position of

the species is quite doubtful ; but I place it here, as the antenne are said to be “ valde

serratis.” It is recorded as found on the 2nd of March in the seeds of an ashy-yellow

leguminous plant growing on the sea-shore.

§ 4. Form short and broad, with large, broad, subperpendicular pygudium ; front coxe

frequently minutely separated at the tip by a minute prosternal lamina; antenne

short, only subserrate ; hind femora but little incrassate, usually armed with a

single tooth, rarely unarmed, or with one or two additional dentecles.

The character of the separated anterior coxe is of importance, as it is an approxima-

tion to what exists in the neighbouring genera Spermophagus and Caryoborus ; it is

unfortunately only very minute, and grades away so as to be quite absent in several species,

52. Bruchus obscuriceps.

Convexus, fusco-rufus, fusco griseoque vestitus ; capite brevi, lato, oculis distantibus ; prothorace transversim

conico; pygidio elongato, obliquiter perpendiculari; antennis pedibusque anterioribus testaceis (illis

anterioribus a processu gracili bene separatis.

Long. 43 millim.

Hab. Mexico, Vera Cruz (Sallé).

Antenne short, the four basal joints slender, the others broad, the seventh to the tenth

transverse ; third joint a good deal longer than the second. Head broad, extremely short,

the vertex obscurely elevate along the middle ; eyes but little prominent, finely facetted.

Thorax transverse, but narrow in front, and becoming gradually much broader behind;

closely covered with a pallid grey pile that much conceals the sculpture, which consists

of a minute, very dense, punctuation and more scattered larger punctures, Elytra rather

finely striate, with patches of pallid fuscous and grey pubescence, scarcely causing a

maculation. Pygidium very long, densely clothed with, pallid grey pubescence, as also

are the under surface and the hind femora; these latter are a good deal dilated, and bear

a rather long tooth and two other smaller, but very distinct teeth near it; the tibiz are |

stout, very little curved, with a quite short apical spur. Last ventral segment elongate

in the middle.

Four examples.

Hab. British Honpuras, Belize (Blancaneauz).

Although closely allied to B. obscuriceps, this species is undoubtedly quite distinct,

being smaller and not quite so convex, with more scanty and less pallid clothing, with

less transverse thorax, the punctuation of which is coarser, and with the lamine sepa-

rating the front coxe more slender. Of the three examples found, one is a male, and

has the apical ventral ring not quite so elongate in the middle as it is in the female.

Three examples.

54. Bruchus muricatus.

Fusco-rufus, abdomine rufo, antennis pedibusque testaceis; pube griseo-flavescente minus dense vestitus ; pro-.

thorace conico, fortiter denseque punctato; elytris brevibus, ad basin muricatis; pygidio valde elongato;

femoribus posterioribus dente elongato armatis.

Long. 53 millim.

Hab. Panama, Bugaba (Champion).

Antenne short, the penultimate joints transverse. yes very little prominent, finely

facetted, very widely separated. Thorax regularly narrowed from the base to the

front, with unusually coarse sculpture. Elytra rather deeply striate, each of the stria

3-6 terminated in front by a small angular elevation. Hind tibie with a long spur at

the apex.

This species, with many points in common with B. obscuriceps, differs in very

important characters, and will be readily recognized by the unusually coarse thoracic

sculpture and the asperities at the base of the wing-cases; the front cox are separated

by a lamina so fine that it can be only detected when looked at directly from behind.

Only one pair was found of the species; the male has the intermediate ventral rings

considerably shorter than they are in the female, and the apical ring greatly abbreviated

in the middle owing to the inflection of the apex of the pygidium.

55. Bruchus inanis.

Brevis, latior, convexus, fusco-testaceus, supra fuscus, griseo-vestitus, in elytris submaculatus; antennis, pedibus

abdomineque, testaceis ; prothorace fortiter transversim conico; femoribus posterioribus dente parvo

armatis. :

Long. 34 millim.

Hab. Muxico, Toxpam (Sallé); British Honpuras, Belize (Blancaneauc).

Antenne short, the joints 6-10 transverse. Head small; eyes but little prominent,

rather widely separated. Thorax strongly transverse, greatly narrowed towards the

front, the surface rather closely clothed with griseous pubescence, which is not

distinctly spotted, and with rather numerous coarse punctures. Elytra short, very

finely striate, clothed with griseous pubescence, allowing two transverse series of

BRUCHUS. | 469

indefinite fuscous spots to be perceived. Hind tibia with acute and slightly prolonged

inferior angle, not long enough to be termed a spur.

This species is no doubt allied to B. obscuriceps, though it has a shorter thorax; the

front coxz are actually contiguous at the tip, nevertheless there is a very slender lamina

concealed by their apices, and this projects beyond the coxz as an excessively minute

process,

Only two examples of uncertain sex were found by M. Blancaneaux ; the ground-colour

in one is more rufescent than it is in the other. The Mexican example is a pinned

individual in bad preservation, but appears to be really the same species. It was

labelled in Sallé’s collection “B. minutus, Fabr.,” but it is clear that this species is

not the B. minutus of either Fabricius or Schénherr; further on (no. 107) I have

recorded another species that is apparently less unlikely to prove to be the Fabrician

insect.

56. Bruchus guttifer.

Brevis, convexus, subtus dense pallido-griseo vestitus, supra tenuiter vestitus, rufescens; in elytris guttulis

minimis pallidis transversim positis ; prothorace transversim conico ; femoribus posterioribus dente parvo

armatis.

Long. 3 millim.

Hab. Muxico, Jalapa (Hoge), Vera Cruz (Sallé); Guatemata, Duefas, Capetillo

(Champion).

Antenne short, the basal joints yellow, the external ones infuscate; the sixth to the

tenth joints strongly transverse. Thorax rather strongly transverse, but regularly

conical, the sides being gradually narrowed from the base to the front, and not at all

rounded in front, dark red, coarsely punctate, and only very sparingly clothed. LElytra

very finely striated, dull red, with six very minute white dots arranged in an irregular

transverse series across the middle. Under-surface and pygidium densely clothed

with pallid griseous pubescence.

The structural characters are similar to those of B. inanis, except that the angle of

the hind tibia possesses a short, slender spur. |

I have seen four Mexican exponents of this species, and two from Guatemala; the

one found at Capetillo is a variety in which the thorax and elytra are fuscous instead

of rufescent.

transverse. Head very short; eyes very widely separated. Thorax short, strongly

narrowed in front, coarsely punctate, the sculpture concealed by the yellow, unicolorous

pubescence. Elytra rather elongate, finely striate, the interstices impunctate. Pygidium

red. Under surface black, except the sides and extremity of the hind body. Legs

entirely red. Hind femora slender, with only a small tooth; tibiee without mucro.

Four examples of the form with unicolorous elytra were met with, and a similar

number of the variety with the base and apex of the wing-cases darker, causing a faint

broad fascia across the middle. The last ventral plate is rather elongate, but in the

male is a little shorter in the middle owing to the greater inflection of the extremity of

the pygidium. This is the only sexual character I can observe. ‘The femora are not

canaliculate. The fasciate variety is represented on our Plate.

Subovalis, sat convexus, niger, tenuiter pruinosus, subnitidus, antennarum basi pedibusque rufis; prothorace parum

Long. 32 millim.

Hab. Guatemata, Mirandilla 1700 feet (Champion).

Antenne short, very stout; five basal joints yellow, the others dark; penultimate

joints very strongly transverse. Head rather narrow; eyes widely separated. Thorax

and elytra sparingly and equally covered with a very fine white pubescence, which leaves

the surface somewhat shining; they are densely and finely punctulate, the latter with

the moderately fine strie very distinctly punctate. Pygidium rather large and broad,

the white pubescence on it and the under-surface more dense. Legs entirely bright red,

the hind femora armed with a moderately long tooth; the tibie straight, armed at the

apex with conspicuous digitations, of which the anterior is not longer than the others.

Front coxe separated by a distinct lamina. In the female the last ventral ring is

slightly longer than the penultimate; in the male it is shorter in the middle, and in

this sex the maxillary palpi are unusually elongate and slender. The femora are not

canaliculate.

Two pairs were found. In one example the surface is fuscous instead of black, pro-

bably connected with immaturity of the specimen.

59. Bruchus instabilis.

subtiliter alutaceis ; pygidio magno convexo; femoribus posterioribus dente parum prominulo instructis.

Long. 22 millim.

Hab. Mexico, Toxpam, Teapa (Sal/é), Paso del Macho (Hége); GuaTEMALA, near the

city, Chiacam, San Gerénimo, Capetillo (Champion) ; Honpuras (Sai/é).

Thorax much narrowed in front where the sides are not rounded, quite dull, the

BRUCHUS. A467

punctuation coarser than usual. Elytra short, the interstices not punctulate, but

covered with a minute roughening or scratching. Pygidium and hind body closely

covered with ochraceous pubescence. Hind femora not dilated, bearing only a single

small tooth; tibia not arcuate, its front angle forming a very short mucro, which,

however, is conspicuously longer than the other terminal digitations. The femora are

not canaliculate, and the sexual distinctions are apparently very slight.

This species is very variable in the colour of the elytra, which may be entirely bright

red or entirely black, the greater number of examples being intermediate, having a red

patch of variable size on each wing-case; in these maculate examples the spot of red

colour is always nearer the base than the apex. Examples with entirely red elytra

were labelled B. gilvipennis, Deyr., in Sallé’s collection; but as the name is only

applicable to a minority of the specimens, I have not adopted it.

60. Bruchus morosus.

Sat latus, niger, subtus griseo vestitus ; elytris ante medium fascia parum conspicua grisescente, antennarum

basi pedibusque rufis; femoribus posterioribus basi nigra, dente lato minus elongato instructis.

Long. 22 millim.

Hab. Mexico, Jalapa (Hoge); Guatemata, Sabo and Purula in Vera Paz (Champion).

Head rather narrow, with small eyes. Antenne short, very broad, four or five basal

joints yellow; second joint quite small, the third and fourth subequal, rather small.

Thorax transverse-conic, much narrowed in front where the sides are a little rounded ;

very densely and rather coarsely punctate, somewhat sparingly clothed with

griseous pubescence, of which there is a more distinct line in front of the scutellum,

and a very small spot on either side of the middle. Scutellum densely clothed with

nearly white pubescence. Elytra rather short, somewhat finely striate, black, with

a faint irregular fascia of griseous pubescence in front of the middle. Pygidium

rather large, densely clothed with griseous pubescence. Hind femora not dilated and

not canaliculate, their single tooth short and broad; tibia moderately stout, not curvate,

without mucro, but with distinctly prominent angle.

Nine examples were found at Sabo, and one at Purula; the description is made from

the Sabo examples. The three Mexican individuals do not differ materially.

and broad; eyes widely separated. Upper surface rather densely covered with a

fuscous pubescence. Scutellum with pallid pubescence. Thoracic punctuation fine

and excessively dense. Pygidium densely clothed with ochraceous pubescence at the

base, where it is arranged in three indefinite, connected patches. Hind femora feebly

dilated, provided on the inner side near the extremity with a slender, rather long tooth,

and on the outer side in the corresponding spot with a rather deep emargination ; tibia

straight, short, with definite, though rather short, apical mucro. There is no lamina

to separate the apex of the front coxe.

The only example found is no doubt a male; the terminal ventral ring is very short,

in the middle still shorter.

This species resembles B. morosus, though not very closely allied thereto.

Antenne short and stout, fusco-testaceous, with the basal joints brighter; joints two,

three, and four rather small, subequal ; penultimate joints strongly transverse. Head not

broad ; eyes widely separated. Thorax greatly narrowed in front, the sides not rounded,

the disc convex, the basal lobe broadly impressed ; the surface shining, rather coarsely

but not densely punctate, about the sides with fine, not dense, white pubescence. Elytra

short and broad, deeply striate, the striae punctate, the interstices rough, but not punc-

tate, the pubescence fine and scanty; each with a large bright red spot, quite at the

shoulder, reaching the base and outer margin, but not the suture. Pygidium very

large, rufescent at the base, black at the apex, but the ground-colour concealed by the

dense fine white clothing ; this is somewhat denuded on two spaces below the middle,

giving rise to the appearance of two black spots. Hind femora not slender, but not

dilated, armed with a tooth very acute, though broad at the base, and with no appear-

ance of denticles; tibia straight, rather stout, not mucronate, but with the anterior

of the terminal angles perceptibly longer than the others. Terminal ventral ring short.

The femora are not canaliculate, and the front coxz are contiguous.

Of this very distinct species six examples were met with by Herr Hoge, and one by

M. Blancaneaux.

Hab. Guatemata, near the city, Capetillo (Champion).

Antenne only moderately long and broad; third and fourth joints slender, subequal,

the penultimate joint about as long as broad. Head small; eyes scarcely at all prominent,

widely separated. Thorax rather short, rounded at the sides so as to be much narrowed

in front, black, very finely punctate, but with some larger, but still quite fine, punctures

scattered over it, slightly shining, the surface receiving a somewhat leaden tint from

the very minute pubescence; basal lobe foveolate in front of the scutellum. LElytra

rather finely striate, each with a large red spot occupying the larger part of the surface,

reaching the outer margin, but not the base, apex, or suture; interstices densely, minutely

punctulate, the pubescence very minute. Pygidium broad, rather large, the pubescence

very fine. Posterior femora not dilated, each with a rather slender acuminate tooth ;

tibie straight, only moderately broad, without mucro.

Only one example was met with in each locality; they represent the two sexes, the

last ventral ring in the male being considerably excised. Although superficially similar

to some of the maculate varieties of B. instabilis, this species is very distinct therefrom ;

the front coxe are separated by a fine lamina, the hind femora not canaliculate.

striate, clothed with pubescence like the thorax, each with a large pale red spot near

the suture. Pygidium yellow. Legs including the front coxe and the hind tarsi

yellow. Hind femora not dilated, but rather short and broad, unarmed; tibie quite

a rather dense yellow pubescence. Elytra short, rather deeply striate, the interstices

aciculate not punctulate; each withavery large pale-red mark nearer the base than the

apex, starting from the outer margin and reaching the suture, except for the sutural

interval which remains black. Pygidium rather abundantly clothed with pallid

pubescence, rather large and convex. Legs bright red, front coxa and the base of the

hind femora black. Hind femora not dilated, and armed only with a small sharp

This and the following five species present an extreme similarity to one another, but

after comparison I am unable to treat them as one species, although I have only one or

at most two of each before me. They agree in having the upper surface densely

punctulate and of a uniform black colour, which receives a somewhat leaden tinge

from the very fine minute pallid pubescence with which it is uniformly covered. In

the present species the antenne are short and broad, with the basal four joints rufous,

the rest black. The thorax is broad, much narrowed in front, curvate at the sides, the

surface very densely minutely punctulate, faintly channelled in front of the scutellum ;

the latter broad. LElytra finely striate, very densely and finely punctulate. Pygidium

similar in colour and clothing to the anterior parts. Front and middle legs rufous at

the apex, becoming black at the base. First ventral ring longer than all the others

together ; breast very coarsely punctate. Hind femora not dilated, each armed with a

the four front legs are bright red; the anterior coxe are separated by a fine lamina.

In other respects similar to B. seclusus.

One example.

71. Bruchus egrotus.

Brevis, parum convexus, subrotundus, niger, subtiliter albido-pruinosus; antennarum basi pedibusque anteri-

oribus ex parte rufis; prothorace elytrisque densissime punctulatis; pygidio basi albido trimaculato ;

femoribus posterioribus dente elongato armatis.

Long. 24 millim.

Hab. Guatemata, Zapote (Champion).

This species is readily distinguished by the three white spots at the base of the

pygidium, the middle one of which is quite conspicuous, but that at each anterior angle

is quite small; the front coxe are distinctly separated, and the mucro at the apex of the

hind tibia is moderately long. In other respects it is extremely similar to B. seclusus.

One example.

72. Bruchus semicolon.

Brevis, niger, subtiliter albido-pruinosus; antennis pedibusque rufis, illis subgracilibus extrorsum fuscescen-

tibus ; femoribus posterioribus (apice excepto) nigris; pygidio basi albido bimaculato.

Long. 24 millim.

Hab. GuateMaua, Capetillo (Champion).

This species is readily distinguished by the large spot of white pubescence at each

front angle of the pygidium, by the more slender antenne, the penultimate joint being

about as long as broad, and by the red posterior legs; the hind tibia is remarkably

broad. The front coxe are apparently contiguous at the apex, and the tooth of the hind

femur is rather long, though, as the unique example is in a very rigid condition, I have

not been able to see these two latter points with complete certainty. The elytra are

rather deeply striated, and the scutellum is not transverse, both covered with white pu-

bescence. The prothoracic punctuation is excessively dense, and there is scarcely any

appearance of a channel at the base.

73. Bruchus cognatus.

Sat latus, subovatus, niger, albido-pruinosus; antennarum basi pedibusque anterioribus ex parte rufis; pro-

thorace densissime punctulato ; femoribus posterioribus dente elongato armatis.

Long. 24 millim.

Hab. Mexico, Saltillo in Coahuila (Dr. Palmer).

This species is not quite so broad as its allies, and the pubescence is not quite so fine,

so that it approaches in these respects to B. pruininus; the first ventral ring, moreover,

is not quite so long as all the rest together; the front coxe are separated by a fine

BRUCHUS. — 473

lamina; the sculpture of the interstices of the wing-cases is aciculation rather than

punctuation, and the scutellum is minute, and clothed with white pubescence. The

front legs are red, but with the tarsi more obscure, and the bases of the femora dark.

One example.

74. Bruchus piger.

Brevis, subovatus, niger, subtiliter albido pruinosus ; antennarum basi pedibusque anterioribus rufis; prothorace

elytrisque densissime punctulatis; femoribus posterioribus dente elongato armatis.

Long. 2 millim.

Hab. Mexico, Guanajuato (Sallé); Nicaragua, Chinandega (Sallé).

This obscure little insect is very closely allied to B. monachus, but is considerably

smaller, and has only four joints red at the base of the antenne, and is further distin-

guished from the allies by the extreme diminution of the coarse punctuation on the

metasternum. The lamina between the apex of the front coxs is excessively minute.

One example from each locality.

§ 5. Ventral rings elongate; pygidium oblique or subhorizontal ; size never very small,

in a single species only does the length descend to 2 millim. Femora only

moderately dilated, armed usually with a tooth and two denticles; rarely one

denticle, and still more rarely both, may be absent.

This group is heterogeneous, but as it contains comparatively few species it would be

of no use for the purposes of this work to subdivide it. I may mention, as additional

characters, that the head is very short, the eyes widely separated, the antennz feeble

and subserrate; the thorax is conic, with the sides convex, or in B. oblongo-guttatus of

peculiar subtransverse form. An important peculiarity of the group is that in several

species the femora of the male are deeply channelled beneath nearly or quite to the

base, while in the female they are of the normal form. This character, however, is

found only in certain of the species.

75. Bruchus humeralis.

Bruchus humeralis, Gyll. in Schoénh. Cure. i. p. 39°.

Hab. Mexico!, Ventanas 2000 feet (Forrer), Almolonga (flohr), Cordova, Capu-

lalpam, Yolos, El Cameron (Sallé), Oaxaca (Hoge); GUATEMALA, near the city 5000 feet

(Salvin), San Gerénimo, San Joaquin in Vera Paz (Champion).

The extension of the red colour in this species is subject to a great deal of variation.

In the male the hind femur is very deeply channelled quite up to the trochanter; there

is not much difference in the last abdominal ring in the sexes, though in the male it is

a little emarginate in the middle. The armature of the hind femur is rather peculiar,

as there is on the hind margin of the large tooth a very obsolete denticle, and at the

base of the tooth a second indistinct denticle.

76. Bruchus cinerifer.

Bruchus cinerifer, Fahr. in Schonh. Cure. v. p. 21".

Hab. Mexico (Chevrolat'), Vera Cruz (Sallé), Jalcomulco (Flohr); Guatamata, San

Gerénimo (Champion).

Herr Flohr obtained this insect from the seeds of a Mimosa. According to an example

from Sturm’s collection, obtained by M. Sallé, it is the B. incanus of that entomologist.

77. Bruchus immunis.

Oblongo-ellipticus, niger, griseo vel fusco vestitus; pedibus quatuor anterioribus antennarumque basi testaceis ;

prothorace transverso-conico, lateribus rotundatis, fortiter punctato; pygidio magno, obliquo; femoribus

posterioribus dente elongato denticulisque duobus armatis.

Long. 5 millim.

Hab. Panama, Pefia Blanca 3000 to 4000 feet, San Lorenzo (Champion).

This species is very closely allied to B. humeralis, but, so far as I can judge from two

examples, is a considerably smaller and more slender insect, with more slender antenne,

paler anterior legs, two well-marked denticles on the femur, and well-marked differences

in the structure of the ventral rings. In the female the apical ring is as long as the

basal one, in the male it is much shorter, and in the middle somewhat excised, so as to

be there only half as long as the basal ring; the intermediate rings are rather shorter

than those of the female of B. humeralis. ‘The two examples before me differ in colour,

one being pale grey, the other fuscous ; there is a faint indication of some red colour at

the base of each wing-case. The male femora are canaliculate, as in B. humeralis.

78. Bruchus viduatus.

Oblongo-ellipticus, nigricans, hic inde rufescens ; antennarum basi pedibusque rufis, tibiis tarsisque posterioribus

obscuris ; prothorace transversim conico, lateribus rotundatis, sat fortiter punctato; femoribus posterioribus

dente elongato denticulisque duobus, subobsoletis, obtusis armatis.

Long. 33 millim.

Hab. Panama, Caldera 1200 feet, Volcan de Chiriqui 2000 to 3000 feet (Champion).

Another very close ally of B. humeralis, though not half the size of the smallest

examples of that species and with the wing-cases a good deal shorter, with no distinct

red mark, and the pubescence of the surface much less white. The structural and.

sexual characters are extremely similar to those of B. humeralis, but in B. viduatus the

apical ventral ring in the female is considerably longer. Both on the upper and under

surfaces there are vague red marks, differing in the two examples, and no doubt variable

and unimportant. Besides the typical pair from Caldera I also refer to the species

_BRUCHUS. 475

another pair from the Volcan de Chiriqui, in which the two denticles of the femora are

less obsolete.

79. Bruchus sallei.

Oblongo-subellipticus, fuscus, griseo vestitus ; elytris tenuiter griseo vestitis, maculis oblongis fuscis, corpore hic

inde plus minusve rufescente; antennis nigris, basi ac pedibus rufis; prothorace transverso, antrorsum

angustato, fortiter punctato; femoribus posterioribus dente elongato denticulisque duobus instructis.

Long. 5-54 millim. .

_ Hab. Mexico, Guanajuato (Sallé), San Luis Potosi (Dr. Palmer); Guatumaua, San

Gerénimo (Champion).

Antenne not stout, the four basal joints red, the tenth joint not quite so long as broad.

Head moderately broad ; eyes but little prominent, widely separated. Thorax short and

broad, much narrowed in front, the sides in front very little rounded, coarsely punctate

and covered with a griseous pubescence. Elytra of a fuscous colour, more or less tinged

with red according to the individual, clothed with a sordid griseous pubescence which

permits oblong spots of the ground-colour to appear; sides and apex darker; third,

fourth, and fifth intervals with a small elevation at the extreme base. Pygidium

elongate, oblique, the ground-colour and pubescence similar to that of the elytra, both

variable. Hind body rather uniformly and closely clothed with griseous pubescence.

Legs sordid red, the femora sometimes marked with black. Intermediate ventral

rings elongate, the apical ring in the female about as long as the basal ring, in the

male much shorter in the middle; in the latter sex the hind femora are deeply canali-

culate to the base. The tooth of the femur is moderately long, the two denticles

placed very near it, rather obtuse; tibia rather slender, straight, its apical truncature

not oblique, the anterior angle not mucronate.

This species was labelled B. ing@ in Sallé’s collection ; but all the evidence I have

been able to procure makes me treat it as not that species. Dr. Palmer bred B. sallei

from the seeds of an Acacia. We have received only one typical example from Gua-

temala. A second example, found at Capetillo, is only 3 millim. long, and has the

antennze yellow, but appears to agree in structural characters with the larger examples,

so that at present I cannot form any valid opinion about it.

Dr. Horn. The Mexican exponent is, however, destitute of the pygidial impressions ; it

species has a long slender mucro at the apex of the hind tibia.

Long. 33 millim.

Hab. Norta America, Arizona (Morrison).—Mexico, Northern Sonora (Morrison).

Of rather narrow, slightly convex form, with the pygidium elongate and more hori-

zontal than usual. Antenne entirely pale yellow, not stout, subserrate, the penultimate

joint about as long as broad. Head short, the eyes widely separated. Thorax with the

sides rounded in front. Scutellum not elongate. Elytra with dark marks at the sides

and apex, and also dark along the suture, bearing a fuscous pubescence with indistinct

paler spots, the punctuation of the strie more than usually distinct. Pygidium clothed

with fuscous, white at the sides, the white extending inwards at the middle. All the legs

yellow. Under surface clothed with white pubescence; terminal ventral ring equal in

length to the basal ring. Hind legs slender; femora not dilated, with a rather small

acute tooth and two small acute denticles; tibia slender, straight, not at all mucronate

at the front angle. Male with a large impression on the terminal ventral. ring, scarcely

visible in the female; femora not channelled.

This species was distributed by the late Mr. Morrison with the name B. prosopis;

although abundantly distinct from that species I think it may possibly prove to be

identical with B. protractus, Horn, described on a single example from the peninsula

of Lower California, |

82. Bruchus insolitus.

Sordide ferrugineus, ochraceo vestitus, pectore nigricante; antennis pedibusque testaceis, pedibus posterioribus

Long. 33 millim.

Hab. GUATEMALA, near the city (Champion).

Antenne short and stout, yellow, the penultimate joints transverse. Thorax nearly as

long as it is broad at the base, much narrowed in front, the sides not rounded, the hind

angles very acute. Scutellum quadrate. Elytra very finely striate-punctate, covered with

a fine pubescence which is scarcely variegate. Pygidium moderately large, densely

clothed with pubescence. Hind femora moderately dilated, armed with a long tooth,

and two acute and prominent denticles, the tibia thick, the knee bent, the apex oblique

so that the anterior angle forms a stout, short, prominent angle. First ventral ring

about as long as the four other rings together. |

A peculiar species, possessing many of the characters of the B. humeralis allies, such as

BRUCHUS. ATT

the more elongate form, the short head, the rather deep dispersed thoracic punctuation,

and the less abbreviate intermediate ventral rings, but with a more elongate thorax and

more acute hind angles thereto than any of the allies. The only example taken is

presumed to be a male, the terminal ventral ring being slightly shorter in the middle

than at the sides, and only about the length of the preceding ring. The femora are

not canaliculate.

Hab. Guatemata, Panajachel 5000 feet (Champion).

Antenne entirely yellow, short, the penultimate joints strongly transverse. Thorax

elongate, greatly narrowed in front, the sides slightly rounded, with a very distinct line of

pallid pubescence extending all along the middle. Elytra elongate, finely striate, with

extremely indistinct linear spots of griseous pubescence near the suture. Pygidium of

a beautiful dark fuscous colour at the apex, and divided along the middle by pallid

pubescence.

Only one example was obtained. The species agrees in structural characters with

B. insolitus, though very distinct therefrom by the coloration of the thorax and pygi-

dium. The specimen is presumed to be a male, the structure of the hind legs and

ventral rings being similar to B. imsolitus.

84. Bruchus championi.

Suboblongus, parum convexus, minus vestitus, rufus; elytris pygidioque tenuiter albido variegatis; prothorace

Long. 3 millim.

Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion).

A very distinct species; the form somewhat that of a minute 2B. oblongo-guitatus, but

the thorax is not margined at the sides. The antenne are yellow, the penultimate

joints strongly transverse. The elytra are short, with a few white flecks at the extreme

base, the scutellum being also covered with white; across the middle there is a very

irregular band of white elongate marks, connected with a short second band behind.

The pygidium is red, with three white marks at the base, and a fainter longitudinal mark

near the apex. The intermediate abdominal rings are unusually elongate, the penulti-

mate ring being about as long as the terminal one. The femora are scarcely dilated,

and the short thick tibia is armed with a definite somewhat short mucro. The unique

example is presumed to be a male, though the apical ring is not atall excised; the hind

femur is canaliculate for more than half its length.

I quote only such synonymy as concerns our region, and even some of this is not

perfectly ascertained. Fabricius gave no locality for B. barbicornis, and I doubt

whether his description applies to this species, but in the Munich Catalogue® the

Fabrician name is recorded as a synonym thereof, and Mexico added as the habitat.

The North-American B. sinuatus, Fahr., is also given® as another synonym, but this

likewise appears doubtful.

The species is very difficult to locate, as notwithstanding its similarity to B. scu-

tellaris as to the structure of the legs, it differs much in the elongate ventral rings

and the oblique pygidium: the femora are canaliculate.

Only three examples have been obtained in our region.

§ 6. Size minute, only from 14 to 2 millim. in length; femora not, or only slightly

incrassate, sometimes simple, their armature slight, at most a small tooth and two

denticles.

As compared with Group §2 the members of the group I am now defining are

distinguished by their still smaller size and diminished femoral structure; but these

characters are not very definite, and the two groups are only separated for convenience

of reference, as each contains a considerable number of species.

conic, much narrowed towards the front, the sides but little rounded, clothed with

griseous pubescence at the sides, dark on the middle, with a fine grey line dividing the

dark part, this latter coarsely punctate. Elytra black, with well-marked griseous spots,

finely striate. Pygidium clothed with griseous pubescence; along the middle this is

denser, so as to form a line. Front and middle legs clear yellow; hind legs also

yellow, but with the base of the femora dark, and the upper part of the tibia some-

times clouded. Femora armed with a slender tooth and two denticles ; tibia with a long

slender mucro at the extremity.

Only one or two examples are extant from each locality. I have some doubt whether

the unique exponent from Mexico really pertains to the species, as it has the surface

less variegate, the spots on the elytra being less definite, and the medial dark space on

the thorax absent.

Closely allied to B. pullatus, but considerably smaller, and readily distinguished

therefrom by the black legs and base of the antenne, and by the almost uniform

clothing of the upper surface; the antenne, too, are rather differently constructed,

being serrate from the fourth joint outwards. The two penultimate ventral rings are

considerably shorter than the second ring.

Antenne serrate from the fifth joint outwards, the penultimate joints transverse,.

the four basal joints pale. Thorax evidently transverse, the sides rounded in front, the

punctuation obscured by the pubescence. FElytra covered with grey pubescence,

immaculate. Hind femur almost unarmed, there being only an extremely minute

tooth; tibia with a very slender, short, apical mucro.

The individuals of this species are smaller than those of any other species of Bruchus

known to me. Its characters bring it near to B. apicalis, but it is very different from

that species by its less elongate wing-cases, which are unicolorous ; it has, moreover, the

fourth joint of the antenne smaller. It is still more similar to B. pedicularius, but is

quite distinct therefrom by the different armature of the hind femora and tibiz, as well

as by the dilute colour of the base of the antenne. 1 do not see any sexual distinctions.

Antenne with the intermediate joints quite small; joints 7-10 strongly transverse.

Front and middle legs entirely red; hind femora black, with the apex broadly red ; tibia.

with an excessively short apical mucro.

This minute insect greatly resembles B. pusillimus, but is readily distinguished from

that species by the colour of the legs, and the two actually differ in several other

respects. No other species amongst the near allies has the antennz so short and clavate

as they are in B. brevipes ; joints 7-11 form an almost abrupt club of about the same

length as the more slender six basal joints.

Although only a single individual has been obtained, and it agrees in the colour of

the legs and antenne with B. flavicornis, yet it is clearly a distinct species, being

smaller, scantily clothed with pubescence, and with much shorter antenne, the joints from

the fifth outwards being transverse. There exists, moreover, a very minute denticle or

tooth on the hind femur, which I have not been able to detect in B. flavicornis. The

apex of the hind tibia is, as in B. flavicornis, destitute of mucro,

This is distinguished from the preceding species by the greater elongation of the

ventral rings, and in this respect connects the following species with the more ordinary

forms of this group. Two examples.

sides greatly rounded in front, the base very feebly lobed in the middle, the punctures

coarse but much concealed by the pubescence. Elytra elongate, finely striate. Ventral

rings elongate.

This is a peculiar species of elongate form. Only three examples have been procured,

. two males and afemale. In the latter sex the ventral rings are more elongate, especially

the terminal one, and the pygidium is correlatively more horizontal in its direction.

In the males there is a rather short mucro at the apex of the hind tibia, which is not

present in the unique female, probably having been broken off by accident.

rather small eyes very prominent, very deeply divided. Thorax rather broader than long,

the sides much rounded in front, the sculpture concealed by the clothing. -Elytra elon-

A small series of nine examples was obtained on the sea-coast. If, as I suppose, I

have both sexes before me, the distinctions between them are very slight.

Angustulus, subdepressus, niger, griseo vestitus ; antennarum basi pedibusque anterioribus rufis, illis latioribus ;

femoribus posterioribus dente minutissimo armatis.

Long. 13 millim.

Hab. Guatemata, Zapote (Champion).

Antenne very broad, thickened from the third joint outwards, the basal two joints

red, the others black, the penultimate joints strongly transverse. Thorax slender, but

not so long as broad, the sides rounded and narrowed in front, the sculpture concealed

by the rather dense clothing. Elytra rather elongate, finely striate. Pygidium with

the pubescence along the middle denser. The terminal four ventral rings elongate.

Front legs red, the apices of the femora and the tibie of the middle legs also of this

colour. Hind femora with a very minute denticle ; tibia slender, without mucro.

Only one example has been obtained. The structure of the antenne distinguishes it

well from the allies, and it is also of unusually narrow form.

99. Bruchus restrictus.

Minimus, sat elongatus, niger, griseo vestitus; arftennarum basi pedibusque anterioribus rufis ; antennis parum

latis, intus subserratis ; prothorace minus transverso ; femoribus posterioribus dente gracili denticulisque

duobus minutissimis armatis.

Long. 1% millim.

Hab. Guatemata, Zapote, San Gerénimo (Champion).

Antenne with the four basal joints yellow, the others black, the penultimate joints

scarcely transverse. Thorax slender, not much narrowed in front, though a little

rounded near the front angles, the punctuation concealed by the clothing. Elytra rather

elongate, finely striate. Front legs entirely red; middle legs reddish with the femora in

great part darker; hind legs entirely black, the tibia with a short mucro at the apex.

Another minute and obscure insect, without any salient character. The thorax,

though rather elongate, has but little of the conical form. Only one example is

extant from each locality.

100. Bruchus optatus.

Minimus, haud elongatus, niger, griseo vestitus; antennarum basi pedibusque anterioribus testaceis ; antennis

sat elongatis, serratis; prothorace transverso-conico, fortiter punctato; femoribus posterioribus dente

gracili denticulisque duobus minutissimis armatis.

Long. 14 millim.

Hab. GuatemMata, near the city (Champion).

Antenne moderately long; the three basal joints obscure yellow, the fourth joint

small, serrate from the fifth joint outwards, the penultimate joints somewhat strongly

transverse. Thorax much narrowed to the front, where the sides are but little rounded. |

Pygidium rather small, perpendicular. Last four ventral rings rather short, subequal

in length. Tooth of the hind femur rather elongate, slender; tibia quite without

mucro.

An obscure insect, which I am not able to associate with any species here described.

It comes nearest to B. restrictus, but has the thorax more conic, with the hind angles

more acute, and the hind tibia quite destitute of mucro. One example.

101. Bruchus viduus.

Minimus, niger, tenuiter griseo-pubescens; antennarum basi pedibusque anterioribus testaceis; antennis sat

elongatis, minus crassis, subserratis; prothorace densissime sculpturato; femoribus posterioribus dente

minuto denticulisque minutissimis armatis.

Long. 14 millim.

Hab. GuaTEMALA, near the city (Champion).

Antenne rather elongate, longer than the head and thorax; third joint a little

longer than the second or the fourth, the fifth triangular, about as long as broad, the

penultimate joints transverse, but only slightly so. Thorax transversely conic, the sides

rather rounded in front. Scutellum minute, covered with white pubescence. LElytra

finely striate, only very minutely and scantily pubescent, as also is the under-surface

of the body. ‘The front legs are yellow, the femora black at the base, the intermediate

tibiz and tarsi yellow.

I find it difficult to form an opinion as to the nearest ally of this obscure insect,

put on the whole it appears best placed near B. restrictus, from which, however, it

differs by the scanty clothing and the armature of the hind legs. The tooth of the

femur is very minute, and there appear to be three very minute denticles beyond it

and one or two distant denticles or serrations in front of it. The hind tibia is a little

curvate and destitute of apical mucro. One example.

§7. Form subcubical, very elevated ; hind femora simple, with a broad channel

beneath, extending from the base to the apex.

So far as our fauna is concerned, this is the most distinct of all the groups adopted

here, and entitled in our region to generic distinction. The lower face of the hind femur

is not in the least convex, but quite straight or very feebly concave, and is limited on

either side by a fine line extending from base to apex, and the inner of these lines may

be minutely crenate for all its length. The antenne are frequently flabellate in the

male, flabello-clavate in the female. The very short thorax is much narrowed in front.

102. Bruchus cubiciformis. (Tab. X XVI. fig. 16.)

Niger, antennarum basi tibiisque fuscis, tarsis rufis, elytris fusco-subnebulosis, pygidio dense ochraceo-vestito,

corpore subtus tantum tenuiter griseo-vestito ; elytris fortiter profundeque seriatim punctatis ; antennis

maris longius, femine breviter, flabellatis.

BRUCHUS. 485

Hab. Mexico, Cordova, Toxpam (Sallé), Cerro de Plumas (Hége); British Honpuras,

Belize (Blancaneaux); Guatemata, El Tumbador 2500 feet (Champion).

Thorax short, greatly narrowed in front, the sides concavely arcuate, the surface rather

uneven, with a longitudinal depression along the middle, the sides of which are but

little elevated, the depression in front of the scutellum broad and indefinite; the

surface bears rather numerous coarse punctures, which are closest and most distinct

near the sides and front margin. Elytra a little depressed along the suture, with

numerous series of very large punctures, the interstices slightly uneven. Pygidium

very elongate, densely covered with a griseous or ochreous pubescence, and with rather

numerous deep punctures covered by the clothing. Under-surface dark, being only

sparingly clothed, with a more or less conspicuous condensation of pallid pubescence on

the posterior portion of the parapleure.

In the male, joints 5-10 of the antenne are each furnished with a long process, each

process being about as long as joints 6-10 together; the fourth joint also possesses a

shorter, though still elongate, process, and the terminal joint is elongate. In the female

the fourth joint is nearly simple, the fifth to the eighth becoming gradually broader, the

fifth being at the apex rather broader than long ; joints 8-10 are similar to one another,

and the terminal joint is short. In the female the last ventral ring is excessively short

in the middle. A male example is figured.

103. Bruchus leucurus.

Niger, supra brunneo vestitus; elytris griseo submaculatis, pygidio corporeque inferius pallide ochraceo

vestitis, antennis pedibusque anterioribus et intermediis testaceis, illis apicem versus fuscescentibus ;

elytris fortiter regulariter, seriatim punctatis; antennis maris longius, femine breviter, flabellatis.

Long. 3-33 millim.

Hab. Mexico (Sallé, ex coll. Sturm), Cerro de Plumas, Paso del Macho (Loge) ;

GuatemaLa, Capetillo, Calderas (Champion).

This species is very closely allied to B. cubiciformis, but is clothed above with more

pubescence, usually of a more pallid colour, and is readily distinguished by the dense

pallid clothing of the ventral rings; the elytra are rather more elongate, even, and

with more regular rather less coarse rows of punctures; the pygidium and last ventral

ring are rufescent, the former more or less maculate with black; but this coloration

is much concealed by the pallid clothing of these parts. The pygidium is considerably

narrower than it isin B. cubiciformis. The structure of the antenne and the last

ventral ring are apparently similar to those of the corresponding sex of B. cubiciformis ;

but in the female the last ventral ring is shorter in the middle, differing in this respect

but little from the other sex; the antennz of the female appear to be more clavate than

those of the same sex of B. cubiciformis, owing to the fact that joints 4-6 are more

slender. I have seen only two examples of the male, both of which are of darker colour

than the females, of which sex four examples are before me. Sallé obtained the

species from Sturm’s collection, the male being ticketed by this latter entomologist

“ Bruchus plumicornis, mihi,” and the female “ Bruchus albiventris, mihi.”

104. Bruchus callirhipis.

Niger, supra variegatus ; elytris albido-nebulosis, pygidio corporeque inferius albido vestitis, antennis pedibusque

anterioribus et intermediis testaceis, illis versus apicem fuscescentibus, pedibus posterioribus rufis, femo-

ribus fuscescentibus; elytris fortiter regulariter seriatim punctatis.

Long. 37 millim.

Hab. Nicaragua (Sallé).

I have seen only two female examples of this species, and, though no doubt very

close to B. leucurus, yet, as the hind body is somewhat differently formed, I have little

doubt they belong to a distinct species. The pygidium does not project so far down-

wards, and is accurately adapted to the last ventral ring at the apex, and the ventral

rings are a little convex in the longitudinal direction. The insect is also of rather

shorter form, and the vestiture of the under-surface paler. The species was labelled

“ B. callirhipis, Chevr.,” in Sallé’s collection, and I have preserved the name for it.

105. Bruchus contaminatus.

Niger, tenuiter griseo vestitus, vix variegatus; pygidio corporeque inferius grisescentibus ; elytris regulariter

crenato-striatis ; antennis serratis,

Long. 3-3$ millim.

Hab. Mexico (Truqut), Guanajuato (Sallé), Jalapa, Oaxaca (Hodge).

This species is of more oblong form than the allies; the surface is less orna-

mented, and the clothing of the thorax and elytra allows the minute rugose sculpture

of the surface to be perceived. The antenne are black, serrate from the fourth joint

outwards, the third joint much longer than the second; the processes given off by the

penultimate joints are short, only about as long as the basal joint. Eyes convex, not

very widely separated. Thorax very short, greatly narrowed in front, the sides slightly

convexly-arcuate ; the surface not uneven, densely minutely rugulose, with a slight

depression in front of the scutellum griseo-pubescent. Elytra rather elongate, very

regularly striate, the punctures of the strize elongate and so close to one another that

the separations between each are indistinct; the interstices densely, minutely, rugosely

fusco-pubescent, very minutely flecked with white.

Twenty examples have been obtained of this species, but I am not able to find any

sexual distinctions among them.

Although the trivial name proposed by Boheman has priority, it cannot be used on

account of the previous B. ramicornis, Er.

The species is very variable in the colour of the surface. It appears to occur only

sparingly south of Mexico, and I have some doubts whether the Guatemalan exponents

may not belong to a distinct species, as the two males found in that country have the

processes given off from the fourth and fifth joints of the antenne longer than they are in

northern examples. In the State of Panama only one individual was met with. A

figure of a male, found at Cerro Zunil, is given.

This is a very doubtful identification. Both Fabricius and Gyllenhal give South

America as the habitat, but the Munich Catalogue mentions Mexico only, and this

may be amere error. The descriptions are very insufficient, and I may therefore state

that I have determined as possibly this species a single minute Bruchus of the

female sex, similar to B. impiger, but not half the size of the smallest example of that

species.

From the description one may suppose this to be a species allied to B. impiger,

possibly indeed a variety thereof.

This is an insect of very deep form, distinguished readily amongst its allies by the

very evident denticulation of the head behind the eyes, these latter having a large

extension in the longitudinal direction, and the constriction behind them being remark-

ably deep and abrupt. The thorax is very short, very greatly narrowed in front, its

sculpture quite fine, the surface very pubescent, the pubescence obscurely variegate,

the surface a little uneven, owing to a slight elevation extending along each side of the

obscure median furrow, and a basal depression on each side external to this. Elytra

deeply striate, the strie with closely placed elongate punctures ; the colour varying

from reddish to fuscous-red or fuscous, more or less minutely and irregularly flecked

with white pubescence. Front and middle legs almost entirely yellow ; femora marked

with fuscous.

Twelve examples were captured : these exhibit no sexual marks, either in the structure

of the ventral rings, or in that of the antenna. These latter organs are shortly

pectinate from the sixth joint outwards, the fifth joint being triangular. Possibly all

the individuals are females. ‘The clothing of the under-surface, though pallid, is not

pure white. The colour of the surface, independent of the clothing, is evidently very

variable. Our artist has not delineated the peculiar postocular structure.

110. Bruchus leucosomus.

Brevis, niger; pedibus anterioribus elytrisque rufis, his plus minusve late nigro marginatis, tarsis pedibusque

serratis.

Long. 24 millim.

Hab. Mexico, San Andres Tuxtla (Sallé); GuaTema.a, San Gerénimo (Champion) ;

Panama, David (Champion).

Antenne entirely black. Head very abruptly constricted behind the eyes, without

any trace of denticle. Thorax very coarsely punctate, black; the white pubescence of

the under-surface though extending upwards, becoming scanty at the sides, and there

is a feeble line of pallid pubescence along the middle; the inequalities of the surface

are very slight. Elytra rather short, with very deep striae, which are crenate, owing to

the confluence of the coarse punctures they bear; of a dark red colour, margined at

the suture as well as at the sides with black, and with only a feeble white pubescence.

Pygidium and under-surface densely clothed with white pubescence, the former with a

transverse black line on the middle. Hind femora and tibize bearing externally much

white pubescence.

This species is easily identified. Only five examples have been obtained, and from

these it is evident that the extent of the red colour on the wing-cases is variable. The

species was ticketed Bruchus propygidialis, Chevr., in Sallé’s collection. One male and

two female examples have been received from Mexico, and a single individual in each

case from Guatemala and the State of Panama.

Kytorhinus rubiginosus, Motsch. Bull. Mosc. 1873, ii. p. 205°.

Hab. Mexico 1.

From the description I think it possible this may prove to be a species allied to B.

leucosomus.

112. Bruchus leucospilus. (Tab. XXVI. fig. 19.)

Rufus; capite cum antennis nigro, elytris lineis abbreviatis niveo-pubescentibus; corpore subtus, pygidio,

prothoracis lateribus et basi niveo-squamosis, coxis posterioribus nudis nitidis; elytris subnitidis, seriatim

fortiter punctatis; tibiis posterioribus longius mucronatis ; antennis maris flabellatis, femine breviter

pectinato-serratis.

Long. 23-33 lin.

Hab. Mexico, Vera Cruz (Salle).

This species is readily distinguished from B. leucosomus by the very long spur of the

hind tibia, a character found also in B. reticulatus. The eyes are very large, and the

head abruptly constricted behind them. The dense white clothing of the under-surface

extends upwards along the sides and across the whole base of the thorax, but leaves a.

broad space along the middle bare ; this space is coarsely punctate, and has a little white

pubescence along the middle. The scutellum is clothed with white pubescence. The

elytra have several snow-white longitudinal marks; these are numerous at the base and

along the suture, and there are also three, one in front, two behind, on the disc of each

elytron ; the surface, except for these marks, is somewhat shining, and bears a rather

coarse sculpture, which looked at from behind seems like series of coarse punctures,

but viewed laterally has more the appearance of coarse striz with large punctures.

The pygidium is snow-white, with a small bare spot at each side near the apex.

Two males and a female have been received, and one of the former is figured. The

species was ticketed B. albomaculatus, Chevr., in Sallé’s collection ; this name is, however,

already in use for another species.

Hab. Panama, Bugaba 800 to 1500 feet (Champion).

Only a simple example of the female sex has been obtained. It appears to be closely

allied to B. leucospilus, but the rufescent colour of the surface becomes here and there

black, and the sculpture of the elytra is different, consisting of broad grooves, separated

by narrow interstices, the grooves being sculptured with very coarse punctures, and

having a little the appearance of being reticulate. The pygidium is immaculate. The

punctures on the hind coxe are remarkably coarse. The white marks on the elytra are

not very conspicuous, and consist of a fine scanty pubescence ; they are placed along the

base and suture, and there is one mark on each elytron towards the extremity.

114. Bruchus excellens.

Brevis, niger; abdomine rufo, subtus niveo-squamoso ; prothorace fortiter punctato, basi undulatim albido mar-

Hab. Panama, Bugaba (Champion).

A single female only has been received of this species. It is allied to B. reticulatus,

but with numerous colour distinctions. The antenne are:broad, pectinate-serrate. The

eyes are rather strongly prominent. The thorax is coarsely punctate, black with a line

of white pubescence extending along the sinuous base, becoming indistinct externally.

Elytra deep black, with a faint line of white pubescence along the suture at the base,

and touching this, a more distinct white dash about the middle of the first groove ;

sculptured by broad, deep grooves, separated by linear interstices. Pygidium red at

each side, densely covered with white pubescence along the middle, this pubescence

divided into two patches by a transverse bare space above the middle. Legs black;

hind tibia at the apex with an acute moderately long spine.

115. Bruchus porosus.

Fuscus, griseo marmoratus ; antennis pedibusque anterioribus testaceis ; prothorace crebre fortiterque punctato;

elytris seriatim profunde punctatis ; antennis (femine ?) intus serratis.

Hab. Guatemata, Calderas 6000 feet (Champion).

Antenne becoming broader from the fourth to the eighth joint. Head with very

prominent eyes. Thorax short, strongly narrowed in front; surface slightly uneven,

but without distinct sulcation, opaque, of a dark fuscous colour, with slender mark-

ings of griseous or pallid fuscous pubescence, allowing the coarse punctures to be

discriminated. Elytra dark fuscous in colour, but largely covered with dense pubescence

of a pallid fawn colour, distributed so as to give a marbled appearance, with rows

of deep pore-like punctures, and with the interstices a little uneven. Pygidium covered

with pallid pubescence like the elytra, but with some indefinite darker spots, and with

the deep punctuation visible though much covered by the pubescence. Hind tibia

with a distinct not elongate mucro.

Of this species only a single example, in a poor state of preservation, has been

obtained. It is apparently a female, and has the antenne less clavate than the corre-

sponding sex of B. impiger. It has no very salient character, but is not apparently

closely allied to any other species, and may be distinguished by the coarse punctuation

of the thorax, and the porous-like punctures on the pygidium.

It is impossible to form any opinion as to this description, but as Motschoulsky’s

other “ Kytorhini” belong perhaps to this section, and as he states the femora to be

unarmed, I place it here. He records it as found in the seeds of a Convolvulus on

the Isthmus of Panama, in March, and it may probably be a species of which I have

not seen specimens.

There is no description of this insect in the ‘ Etudes,’ but merely a comparison with

a new species from Burmah, and in the Bull. Mosc. it is briefly characterized in tabular

form ; it is probably near to B. pusillimus, but the scanty characters mentioned do not

accord altogether therewith.

SPERMOPHAGUS.

Spermophagus, Schonherr, Cure. i. p. 102.

Zabrotes, Horn, Tr. Am. Ent. Soc. xii. 1885, p. 156.

This is a widely distributed genus, its largest and finest forms being found in the

New World. The species are readily distinguished by their possessing two articulated

spurs on the hind tibia. Dr. Horn (Joc. sup. cit.) has recently separated some of the

North American species under the name of Zabrotes, but this step appears premature.

The type of Spermophagus is S. titivilitius, Boh. Dr. Horn, however, differentiates

his Zabrotes not from this form, but from S. robinie, Fabr., but I think it possible from

itivilitius that it may prove to be structurally more similar to

Dr. Horn’s Zabrotes than to Spermophagus robinie. The minor structural characters

in the Bruchide are remarkably variable, and the separation of the front coxee is one of

the most variable characters in the family. Another character relied on by the talented

American Coleopterist to differentiate the genus from Spermophagus, I am not able to

confirm ; he speaks of the claws as absolutely simple, but in the species of our fauna

which I refer with very little doubt to Zabrotes, I find that though the claws are minute,

yet they are lobed at the base, much as in other Bruchide. At present, therefore, the

genus can only be accepted as a section of Spermophagus containing the European S.

cardui, and other Eastern forms in addition to the New World species for which it was

instituted.

on each side, the surface only minutely sculptured, the sculpture concealed by the fine

pubescence, which is black, varied with indistinct grey patches, the most conspicuous of

which is an angular mark in front of the scutellum. Elytra short and broad, finely

striate, black, more or less variegate with grey pubescence ; this sometimes forms a distinct

mark on the middle of each side. Pygidium extremely broad, more or less covered with

grey pubescence, and with a more condensed line of such pubescence along the middle.

Under-surface more uniformly covered with grey pubescence ; the hind coxe bare, with

only a few obsolete punctures; the middle of the metasternum in front distinctly

depressed, and with a greater condensation of the pubescence in the depression.

This species is very variable in the markings of the upper surface ; specimens nearly

evenly covered with grey pubescence were labelled “ Bruchus leucogaster, Kunze” in

Sallé’s collection, and other individuals where the black predominates, allowing a single

incomplete pale fascia to be seen, “ B. cingulatus, Kunze.” The majority of the exam-

ples obtained have a number of indefinite oblong griseous marks forming two or three

irregular transverse series on the wing-cases. S. semifasciatus, Schénh., is no doubt

closely allied to the present species, and an example from Guatemala bearing this

name is extant in our National collection. Schénherr’s locality for 8. semifasciatus is,

however, Barthélemy, and his description does not agree sufficiently with our insect to

admit of its being treated as his species. The North American species of Zabrotes,

described by Dr. Horn, appear also to be very close to S. pectoralis, but are described

ag possessing more or less coarse punctuation on the thorax.

2. Spermophagus propinquus. (Tab. XXVI. fig. 20.)

Breviter ovalis, parum convexus, nigerrimus ; elytris albido semifasciatis, prothorace pygidioque medio pallido-

Long. 2 millim.

Hab. GuatemaLa, Zapote, Duefias, Capetillo (Champion); Panama, Volcan de

Chiriqui between 2500 and 4000 feet, Tolé (Champion).

This species is extremely similar to the semifasciate form of S. pectoralis, but has no

trace of the pectoral depression, and the marks on the upper surface and pygidium,

though few in number, are very definite on the intense black ground; the form, more-

over, is rather shorter and the antenne are not quite so elongate.

Only six examples have been obtained. Probably the species varies somewhat in

the markings, as two of the specimens do not possess the white mark on the wing-cases ;

but this is possibly due to abrasion.

front margin separated by a space about as long as the first joint of the antenne. Thorax.

transverse, the sides rounded and narrowed in front, nearly straight behind, the hind

angles obtuse, the surface evenly covered with deep and coarse rather distant punctures,

and with a minute punctuation besides, the latter concealed by the rather abundant

pubescence. Scutellum elongate, parallel-sided, with a small acumen in the middle

behind. Elytra elongate, rather deeply striate, the striz crenate; pubescence uniform,

quite without spots; each stria has on the interstice on each side of it a series of fine

punctures, each puncture bearing a short fine hair. Pygidium clothed like the elytra,

and with a line of more condensed pubescence along the middle.

In the male the antenne are a little longer than they are in the female. Thisis the

only sexual distinction I can detect.

4, Spermophagus dispar. (Tab. XXVI. fig. 21.)

Elongato-ovalis, piceus, pubescentia griseo-ochracea equaliter vestitus; antennis pedibusque rufis ; oculis con-.

vexis, parum distantibus, fortiter granulatis ; prothorace fortiter punctato; elytris profunde striatis.

Long. 7-9 millim.

Hab. Panama, Bugaba, David, Caldera in Chiriqui, San Lorenzo (Champion).

This species is very similar to S. gravidus, but is smaller and less convex, with greater

discrepancy between the sexes, and readily distinguished by the‘ smaller space separating

the eyes; in this last respect there is a sexual difference, the male having the eyes

rather larger, so that in this sex the interocular space in front is only about as broad

as the second joint of the antenne, while in the female it is slightly greater; the

antenne of the male are a good deal longer, and the inner apical angle of joints 4-10

more acute than in the female. In each sex the second and third joints of the antennz

are rather shorter and stouter than they are in S. gravidus, and the punctuation on the

interstices and the pubescence arising from it are less, and the strie are rather finer.

Mr. Champion secured a series of about twelve examples at Caldera, eight at David,

and one or two at each of the other localities.

5. Spermophagus lineolatus.

Spermophagus lineolatus, Motsch. Bull. Mosc. 1878, ii. p. 248°.

Hab. Guatemata, San Joaquin, San Gerénimo (Champion); Nicaragua!; Panama,

Bugaba (Champion).

Mr. Champion found only one example in each locality, and it is by no means certain

that they belong to the species Motschoulsky described, or even that these examples

are themselves conspecific, though the differences are only in the size, and the details of

SPERMOPHAGUS. 495

colour and punctuation; Motschoulsky leaves it to be inferred that the antenne of his

species are black, except at the base, and this is not the case in the two examples found

by Mr. Champion. These individuals appertain to a species closely allied to S. dispar,

but are not so large, and have the pubescence arranged so as to form somewhat indi-

stinct lines on the thorax and elytra, and the eyes more widely separated.

6. Spermophagus pollens.

Major, latus, niger, supra brunneus, fulvo-pubescens; prothorace sparsim fortiter punctato, elytris profunde

striatis.

Long. 10 millim.

Hab. British Honpuras, Belize (Blancaneauz).

Antenne black, feebly serrate internally. Eyes rather widely separated. Thorax

rather short, its sides a little curved, greatly narrowed from the base to the front, the

rather coarse punctuation not quite regularly distributed and greatly concealed by the

abundant pubescence. Scutellum oblong, rather broad, only indistinctly pointed.

Elytra with deep striz, which are rather closely punctate, and without hairs. Pygi-

‘dium concolorous with the upper surface; under-surface and legs black, rendered

grisescent by pubescence. Outer spur of the hind tibia very elongate.

Although only one example has been received, this is pretty certainly a quite distinct

species; the black under-surface, and tawny red upper surface quite without variegation

are peculiar to it. The form of the apex of the scutellum is not quite clear to me,

owing to the pubescence, but I think it is certainly not tricuspid.

7. Spermophagus obductus.

Piceus (prothorace elytrisque brunneis), fulvo-pubescens ; prothorace utrinque fortiter punctato; scutello

oblongo, apice tricuspidato ; pygidio concolore.

‘Long. 6-7 millim.

Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet, San Feliz (Champion).

Antenne piceous, feebly serrate. yes large, coarsely granulated, rather widely

separated in front. Thorax rather elongate, greatly narrowed in front, the surface

densely, finely punctured, with larger punctures which are not present on the middle.

Scutellum moderately long and broad, evidently tricuspid behind, with the intermediate

tooth the longer. Elytra elongate, rather deeply striate, the striz only obscurely

crenate. Pygidium nearly concolorous with the elytra, with a fine line of rather denser

ochreous pubescence along the middle. Under-surface blackish, hind body paler.

This species, of which I have only seen two examples, is readily distinguished from

S. dispar by the more conical thorax, with diminished coarse sculpture on the middle.

Long. 6 millim.

Hab. Mexico, Vera Cruz, Toxpam (Salié); Brirtiss Honpvras, Belize, R. Hondo

(Blancaneaux) ; Guatemata, Zapote (Champion) ; Panama, Bugaba (Champion).

Antenne moderately long, only obscurely serrate, obscure black, the two basal joints

obscure red, more or less infuscate. Eyes large, coarsely granulate, separated in front

by a space about as broad as the lengths of the second and third joints of the antenne-

together. Thorax strongly transverse, the sides greatly narrowed in front, much

rounded, the surface closely and very minutely punctulate, on the outer portions with

larger punctures, but all the sculpture much obscured by the rather rough pubescence.

Elytra elongate, rather deeply striate, the striz finely and indistinctly crenate, the inter-

stices slightly convex, some of them very slightly more elevated behind, the pubescence

like that of the thorax, not variegate. Pygidium of the dull black colour of the under-

surface, with a fuscous and ochraceous pubescence, and with a denser line of the latter

colour along the middle. Front coxe separated only by a slender process of the pro-

sternum ; metasternum in the middle in front more than usually prominent.

This is an obscure-looking insect, readily distinguished from its allies by the much

diminished separation of the front coxe. Only eight examples have been obtained.

The species was labelled Bruchus hoffmanseggi, Schonh., in Sallé’s collection, and it is.

possible it may prove to be that species; but I think the probability is in the other

direction, S. hoffmanseggi being a Brazilian insect. (Schonherr’s record of this latter

species as North American as well as Brazilian is probably erroneous, especially as it

appears to have been made only on indirect evidence.)

9. Spermophagus togatus.

Elongato-ovalis, piceus, ochraceo vestitus; antennis pedibusque rufis, pubescentia ochracea in elytrorum inter-

stitiis alternis magis condensata, hic inde subinterrupta; prothorace transverso, sparsim sat fortiter

punctato; scutello sat elongato.

Long. 5-6 millim.

Hab. Guatemata, Capetillo (Champion).

The coarse punctuation on the thorax is scanty and not so conspicuous as in other

species; but it is not absent from the disc. ‘The rough yellow pubescence of the wing-

cases is a good deal thicker on the interstices, and here and there is vaguely interrupted

so as to divide it indistinctly into elongate patches. The front coxe are separated by a.

moderately broad process, which has an obtuse apex, this being received on the meso--

sternum considerably above the lower level of the latter. The middle coxe and the

hind legs are infuscate.

Though very similar to S. odscurus this species is distinguished by numerous.

characters, among which the difference in the separation of the front coxe is most.

important. Only two examples have been met with.

SPERMOPHAGUS. 497

10. Spermophagus spectabilis.

Ovalis, fusco-niger, griseo vestitus ; prothorace elytrisque fusco ochraceoque variegatis, antennis pedibusque

fuscis; prothorace in medio absque punctis majoribus ; scutello sat elongato ; elytris subtilius striatis.

Leng. 6 millim.

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

Thorax very strongly transverse, with three small spots of yellow pubescence on

either side ; the larger punctures conspicuous at the sides, but absent along the middle.

Elytra vaguely variegate, there being on some of the interstices a development of

ochraceous pubescence, which does not form, however, distinct spots or definite patches.

Pygidium variegate with ochreous and fuscous. Under-surface unicolorous, grisescent,

except for a spot of ochreous pubescence on the side of the first ventral ring, and

smaller and more indistinct spots on the following rings.

Although closely allied to S. togatus this species is probably distinct; it is broader

and has the front coxe rather more widely separated, the thorax maculate, without any

coarse punctuation on the middle, and the wing-cases with much less ochreous pubes-

cence. Only one example has been received.

11. Spermophagus leporinus.

Ovalis, fusco-niger, griseo pubescens; superne guttulis minutis albidis ornatis; antennis pedibusque rufis ;

prothorace fortiter transverso, tantum ad latera punctis majoribus impressis ; scutello parum elongato ;

elytris subtilius striatis.

Long. 5 millim.

Hab. Guatemata, San Gerénimo ( Champion); Panama, Taboga Island (Champion).

Another close ally of S. togatus, but readily distinguished by the small white dots

existing on the upper surface; there are three of these, but only indistinct, on each

side of the thorax; on the alternate interstices of the elytra they are more numerous

and distinct; the pubescence of the upper surface is of a uniform griseous colour,

except for the white spots, and the fact that behind some of the white dots on the

elytra the surface is indistinctly darker. The middle of the thorax is without coarse

punctuation, and the sides only are indistinctly punctured. The pygidium is rather

sparingly and irregularly clothed with grisescent pubescence. The structure of the

prosternum differs slightly from that of S. togatus, it being less constricted at the apex

of the coxe, and a little more prolonged behind: the metasternum is not all prominent

in the middle in front.

One example from each locality.

12. Spermophagus luctuosus.

Antenne rather*slender, distinctly serrate internally. Eyes moderately large, rather

widely separated. Thorax very short, convex, greatly rounded in front, evenly covered

with coarse somewhat distant punctures (in addition to the minute punctuation), with

griseous pubescence, and a very obscure ochreous spot on either side of the middle.

Scutellum rather short and broad. Elytra finely striate, the striz distinctly crenate,

covered with scanty griseous pubescence, on the alternate interstices with numerous

ochreous spots, more distinct behind than at the base. Pygidium dark, somewhat

sparingly griseo-ochraceo-pubescent, and with a fine line of such pubescence along the

middle. Under-surface uniformly griseo-pubescent; front legs obscure red, the hind

legs darker. Front coxe moderately separated, the process not constricted, slightly

prolonged, touching the mesosternum slightly above the lower level of the latter.

Closely allied to S. leporinus, but readily distinguished from that species by the

thoracic punctuation, and the different coloration of the upper surface.

One example from each locality.

13. Spermophagus perfectus.

Elongato-ovalis, fusco-niger, griseo pubescens, vix maculatus; antennis pedibusque rufis; prothorace conico-

transverso, medio absque punctis majoribus.

Long. 53 millim.

Hab. Mexico, Tehuantepec (Sallé).

Antenne slender, entirely red. Eyes coarsely granulate, moderately separated.

Thorax rounded at the sides and greatly narrowed towards the front, evenly covered

with griseous pubescence, which conceals the sculpture; there is, however, no coarse

punctuation along the middle, and at the sides it is only obscure. Scutellum oblong,

rather short. Elytra very finely striate, the strie not distinctly punctured, and greatly

concealed by the nearly uniform griseous pubescence, on which are a few irregularly

placed minute fuscous spots. Pygidium pale red, with pubescence like that of the

elytra. Legs red, the hind ones darker. Front coxe rather widely separated, the

process distinctly prolonged to form a short broad termination received on the apex

of the mesosternum exactly at the level of its junction with the metasternum, so that in

fact the apex of the process almost touches the metasternum between the middle legs.

Although very similar to S. togatus this species is readily distinguished by the sternal

characters; it is, too, more uniform in its colour, and has a longer thorax. Only one

example has been received.

14. Spermophagus trisignatus.

Ovalis, fusco-niger, ochraceo pubescens, vage subvariegatus ; antennis pedibusque rufis; prothorace transverso,

(Blancaneaur); Guatemata, Mirandilla, Cubilguitz ( Champion) ; “PANAMA, Boquete

(Champion).

This species is very closely allied to S. perfectus but is of less elongate form, and the

pygidium has a dark mark at each upper angle, and a more variable one towards the

extremity : the sternal structure is almost the same as in S. perfectus.

Six examples.

15. Spermophagus geminatus.

Ovalis, piceus, minus dense griseo pubescens, superne guttulis albidis minutis ornatus; antennis pedibusque

Long. 34 millim.

Hab. Panama, Tolé (Champion).

This species is very similar to S. leporinus though much smaller; the antenne are

comparatively short, and the eyes are smaller; but it is readily distinguished by the

sternal structure, the prosternal process touching the mesosternum a little nearer the

apex of the latter, and the prosternum is comparatively shorter and rather broader.

There is no line along the middle of the pygidium, which is concolorous with the

elytra.

Only one example has been found.

16. Spermophagus rufulus.

Ovalis, rufulus, griseo pubescens, elytris submaculatis; prothoracis medio absque punctis majoribus; scutello

minuto,

Long. 32 millim.

Hab. Guatemaa, Teleman in the Polochic valley (Champion),

Antenne pale red, rather short, the penultimate joint about as long as broad. Eyes

moderately large, coarsely granulated. Thorax moderately transverse, densely minutely

punctured, with larger, but still not conspicuous, punctures on the lateral portions.

Elytra clothed with pallid pubescence, indistinctly variegate with fuscous spots.

Pygidium pale red, clothed with pallid pubescence, unimaculate.

The sternal structure is almost the same as in S. geminatus, the short prosternal

process being received by the prosternum near, but not quite at, its lower part. It is

possible that the minute condition of the scutellum is due to its being partly concealed

as the result of some abnormal development of the adjacent portions of the elytra; but

even if this be the case, the different colour and the absence of white spots would

prevent the insect being considered that species. It has a good deal of resemblance

also to S. scutellaris, and it is possible the scutellum may naturally be similar to what

exists in that species; still the prosternum in S rufulus is so much more largely deve-

loped between the cox that the two cannot be considered as allied.

Hab. Brirtsn Honpvras, Belize (Blancaneaux); GuateMALA, Chacoj in the Polochic

valley (Champion).

Antenne rather short, red; eyes only moderately large, coarsely facetted, widely

separated in front. Thorax very short, rounded and narrowed at the sides in front,

furnished in addition to the minute punctuation with larger punctures which exist on

the middle as well as at the sides, covered with a rather scanty griseous pubescence,

and some indefinite ochraceous spots. Elytra rather deeply striate, the strie at the base

distinctly crenate, the alternate interstices with rather numerous spots of ochraceous

pubescence. Pygidium concolorous with the elytra, not spotted. Front coxe rather

widely separated, terminating behind as a sharp spine projecting on the apex of the

metasternum, somewhat after the fashion normal in the family Dytiscide.

Only four examples were met with. The species bears an excessive resemblance to

S. luctuosus, from which it is perfectly distinguished by the prosternal process. .

18. Spermophagus scutellaris.

Ovalis, angustulus, rufo-testaceus, griseo pubescens, sepius circa scutellum plaga magna fuscula; elytris vage

minuteque fusco subguttatis ; pygidio medio longitudinaliter vage fusco signato.

Long. 33 millim. .

Hab. GuatEMA.a, near the city, Capetillo, Duefias, Zapote, Cerro Zunil (Champion) ;

Nicaragua, Chontales (Janson); Panama, Bugaba (Champion).

Antenne rather feeble, yellow, the second joint about equal to the third. Head

with moderately large, convex, coarsely facetted eyes. Thorax strongly transverse, very

densely and minutely punctured, finely griseo-pubescent, not spotted, with very faint

indications of larger punctures at the sides. Elytra very finely striate; pygidium

concolorous with the elytra, with a longitudinal and rather indefinite fuscous mark on

the middle. Scutellum narrow, small.

S. scutellaris may readily be distinguished from the preceding species by the dimi-

nished size of the third joint of the antenna. The front coxe are only slightly separated ;

the process is only slightly prolonged backwards behind them, and is received on the

front of the mesosternum a little above its apex; the longer spur of the hind tibia is

rather short. Mr. Champion secured ten examples at Capetillo ; but we have only one

or two individuals from each of the other localities. All the examples from Guatemala

have an irregular triangular dark mark round the scutellum; this is much reduced in

size in the two exponents from Nicaragua, and is completely absent in the unique

example from Bugaba.

Antenne ferruginous, feebly serrate ; third joint twice as long as the second, the tenth

a little longer than broad. Head broad; eyes large, very coarsely facetted, only mode-

rately distant in front. Thorax strongly transverse, moderately narrowed in front, the

front margin broader and less rounded than usual, the surface very densely and finely

punctured, with some larger punctures at the sides, covered with fine griseous pubes-

cence, and sprinkled with a few minute white marks. Llytra ferruginous, more or less

infuscate, and with some black marks, covered with a very fine pubescence of a griseous

colour, more or less marbled with white. Pygidium nearly entirely occupied by a large

oval mark of dark fuscous colour, a little darker above, and surrounded by dense pallid

pubescence. Inner carina of the hind margin of the posterior femur distinctly emar-

ginate at the extremity. Front cox widely separated, the prosternal process short,

received into a definite cavity at the apex of the mesosternum. This species agrees in

many respects with Gyllenhal’s description of S. cistedinus, but not with examples from

Cuba so named by Jekel in our national collection at Kensington.

20. Spermophagus marmoratus. (Tab. XXVI. fig. 24*.)

Hab. Muxico (Sallé); Panama, Volcan de Chiriqui, Bugaba (Champion).

Head black, broad and short ; eyes moderately large, finely facetted, widely separated.

Antenne black, moderately broad, feebly serrate, the tenth joint rather longer than

broad. Thorax transverse conical, pale, without distinct punctuation, densely pallid-

pubescent, with some indistinct fuscous nebulosities near the front, the surface depressed

in front of the scutellum; this latter oblong, rather short, rounded behind. Elytra

similar in colour to the thorax, densely pubescent, so that the striation is quite indi-

stinct, on the apical half largely marked with black in an irregular manner. The large

pygidial mark is formed of dense pubescence, and is so shaded that when looked at

from behind it has the appearance of a cavity extending to the interior of the insect.

Front and middle legs yellow; hind femora black, yellowish at the apex, the tibie

variegate.

This is a remarkably distinct species: the prosternum widely separates the front legs,

and is margined at the sides; its process is received into a cavity on the lower face of

the mesosternum, separated by a considerable space from the metasternum.

Six examples were met with. The unique Mexican exponent is in an extremely

dirty state, and is apparently a variety of narrower and more elongate form, with the

marmorations of the wing-cases extending more to the front.

Ovalis, ochraceo fuscoque variegatus ; antennis basi pedibusque rufis, illis extrorsum nigris; scutello angusto,

Hab. Mexico, Vera Cruz (Saldé).

This is a very distinct species, readily distinguished by the elytra and pygidium being

covered with numerous and very distinct marks, arranged quite irregularly, of dark

chocolate and griseo-ochraceous colours. The eyes are small, but prominent and mode-

rately coarsely facetted; the penultimate joints of the antenne are transverse. The

thorax is strongly transverse, and has no coarse punctuation on the middle; there are

some coarse punctures, much obscured by the clothing, at the sides; the surface is

variegate with colours similar to those of the elytra, but the spots are not so sharply

defined. The scutellum is remarkably narrow and elongate. The front coxe are not.

very widely separated ; the prosternal process projects scarcely at all backwards, and is

received on the anterior face of the mesosternum considerably above its lowest point.

One example.

scarcely three times as long as the thorax, extremely finely striate; black, irregularly

irrorated with grey; the thorax variegate in a similar manner, so that the upper surface

has a very mottled appearance. Pygidium grey, mottled with black. Front coxe

moderately distant; prosternal process very short, received on the front of the meso-

sternum a little above the apex of the latter, which is not excavated for its reception.

This species is allied to S. barcene but is of a darker colour, and is readily identified

by the quite flat eyes. Six examples have been found.

“minute reticulatis;” and this suggests that the species may be near S. barcene or

S. trroratus.

IT regret that I have not been able to make the acquaintance of this species, which

was designated by Schonherr as the type of Spermophagus. I cannot form any opinion

as to its position, no special structural characters being alluded to in the description.

CARYOBORUS.

Bruchus (Grex B. Caryoborus), Schonherr, Cure. i. p. 92.

Caryoborus, Horn, Trans. Am. Ent. Soc. iv. (Jan. 1878), p. 312.

Bruchus (pars), Gemm. & Harold, Cat. x. p. 3219.

This genus may be retained, though it is not easy to differentiate it from Bruchus by

any character that is quite invariable in the two genera. The separation of the front

coxee is of no avail, as some Eastern Caryobori have them contiguous. The thorax

margined all round, and the peculiar structure of the femora, in conjunction with the

elongate wing-cases, suffices to distinguish it. The femora are very broad and com-

pressed, and terminate beneath as an edge quite without longitudinal groove or sulcation.

A similar structure of the legs prevails in certain Bruchi of the Section “ Pachymerus ”

(Group 1 huj. op.), but is accompanied there by a great abbreviation of the hind body

and wing-cases. C. chiriquensis here described affords a fresh illustration of the

difficulty of arranging the Bruchide in sharply-defined genera. Hitherto Spermophagus

has been considered as quite satisfactorily distinguished from the other members of the

family by its species possessing two articulated spurs on the hind tibia: the Caryoborus

I am now speaking of is, however, provided with two small tibial spurs, though in other

respects a typical member of the genus.

Caryoborus is a very widely-distributed genus ; but the Eastern species are insignificant

They are apparently rare insects, and our region no doubt possesses a greater number

of species than we are able to record at present.

Hab. Mexico, Tuxtla 1, Putla, Chiapas, Cosamaloapan (Sa/é).

The examples we have received of this species are only five in number, and are in a

bad state of preservation. They vary in colour and somewhat in punctuation, and

there may possibly be more than one species among them ; but this I find it impossible

to decide. The darker examples come very near to C. arthriticus, Fabr.

Hab. Panama, Volcan de Chiriqui (Champion).

Antenne elongate, serrate from the fourth joint outwards, the joints not impressed.

Head with very large eyes, which are but little distant in front. Thorax sinuate at

each side, so that the hind angles are slightly prominent and acute, with a few coarse

punctures near each outside, and a divided patch on the middle. LElytra not striate,

with rows of punctures which at the base are coarse. Pygidium slender, subacuminate.

Front coxe widely separated; hind femur with a series of very coarse denticulations

placed on a raised margin, extending more than halfway towards the base, terminated

by a longer tooth, the basal portion of the femur quite without serration or denticles.

Four examples were found of this distinct species. It will be readily identified by

the greater development of the femoral serration ; indeed, it may probably prove to be

entitled to generic distinction, as the hind tibie possess at the extremity two minute

articulated spurs.

3. Caryoborus testaceus.

We have not received any Caryoborus corresponding with this description; the size

given for it, viz. 23 lin., is too small for C. rubidus, to which in many other respects it

appears to be similar.
