I. — On the Halticidas of the Canary Islands. By T. Vernon

Wollaston, M.A., F.L.S.

In the following paper I propose to enumerate such members of the

Halticidce, amounting in all to eighteen well-defined species, which

have been hitherto observed in the Canarian archipelago. Their

detection is due to the combined researches of John Gray, Esq., and

myself, in January and February of 1858 (whilst visiting the various

islands in his yacht, the " Miranda," in which he afterwards sailed

for the "West Indies) ; and to those, subsequently, of myself alone

during the five following months of the same year, as also during

February, March, April and May of 1859. And since, therefore, the

whole seven islands have been explored (indeed four of them twice

over, and some very carefully), it is believed that the subjoined list

will give a fair approximate idea of the entire Halticideous fauna of

that sub-African Group. I have been mainly induced to undertake

it through the instigation of my friend M. Allard, of Paris, who is

preparing a Monograph of the European and North-African forms,

and in which therefore the species of these Atlantic islands should

be properly inserted.

The present interesting little .Haiti ca is closely allied, in affinity

and general facies, to the European H. atropce, of which I possess

specimens communicated to me by M. Allard. It is, however, a trifle

smaller than that insect, and its head and prothorax are pale rufo-

testaceous, instead of black ; its limbs also are paler, its punctuation

(although coarse) not quite so rugose, and the dark portions of its

elytra are very much narrower and less developed. I captured it

abundantly throughout the whole district immediately above the

Puerto de la Orotava, in the north of Teneriffe, during February and

March of 1858, — where it was entirely confined to the Physalis

aristata (a plant intimately allied to the Atropa Belladonna, being of

the same natural family, and, as I am informed by the Rev. R. T.

Lowe, possessing nearly the same chemical properties), on the leaves

of which shrub it subsists. I have much pleasure in dedicating it

to M. Allard, to whose kindness I am indebted for an accurate com-

parison of my Canarian Halticidce with his large collection of Euro-

pean and North-African types.

A metallic species of very variable colour, shading off from bright

cyaneous-blue into golden-green, and almost, at times, into coppery-

brown. It is attached to the foliage of the various large Euphorbias,

and was taken on the E. Regis Jubce by Mr. Gray and myself on the

cliffs above the Salinas, in the north of Lanzarote, during January

1858 (in which same locality I captured it again, abundantly, in

March of the following year) ; as also, by myself, on the mountains

above San Martao, in Grand Canary ; on the E. piscatoria above the

Puerto de la Orotava, of Teneriffe ; and in the district of El Golfo,

in the west of Hierro. I have dedicated it to my learned and excel-

lent friend the Barao do Castello de Paiva, to whose researches,

especially in Madeira and Portugal, I have been frequently indebted

for many additions to my collection.

At first sight the present insect and the following one are some-

what alike ; nevertheless, apart from the generic characters (of the

longer legs and hind feet, &c.) of Longitarsus, the H. crassipes may

be known by its more quadrate prothorax, stouter antennae (which

have four of their basal joints, instead of only three, more or less

testaceous), and by its more finely punctured elytra. Its four ante-

rior male tarsi have their basal joint greatly dilated, so as far to

exceed the second, — a structure which is more or less expressed in

most of the Halticidce, but which in the H. crassipes is peculiarly

conspicuous. I am informed by M. Allard, of Paris, that it is un-

questionably new, though slightly akin to his Aphthona jlaviceps, —

which, however, is smaller, with its prothorax and antennae shorter,

and the feet of its males less expanded, <fec. It is apparently rare ;

nevertheless I have taken it sparingly at the Agua Mansa, in Tene-

riffe ; and from off plants (I think chiefly Semperviva) growing on

the damp rocks in the deep sylvan ravines of Palma, — especially the

Barranco da Agua, towards the north-east of the island.

The prima facie distinctions (apart from generic ones) between

the present insect and the last one have been already pointed out.

It is much allied, at first sight, to the common L. tabidus of more

northern latitudes ; nevertheless it is less convex and more strongly

punctured than that species, its prothorax is less abbreviated and

rather more narrowed in front, its antenna) and legs are longer, and

the basal joint of the four front male feet is altogether larger and

broader. Its habits, too, are quite different, since it appears to be

almost entirely attached to the leaves of the Kleinia nerii folia, on

which it often exists by thousands, and whole plants of which I have

occasionally observed almost defoliated by its attacks. In such posi-

tions I have taken it abundantly in the waste grounds above the

Puerto of Orotava, and near Santa Cruz, as also in the sylvan

districts of the Agua Garcia and Taganana, of Teneriffe ; in the

Barranco above Santa Cruz, of Palma ; and towards the coast, in

El Golfo, of Hierro.

Habitat in foliis Echiorum (praesertim E. simplicis) in locis editioribus

Tenerift'aa et Hierro.

Before examining critically this beautiful Longitarsus, I had re-

garded it as a mere topographical state of the Madeiran L. Masoni

(the L. Isopleoridis, Ins. Mad. 443, tab. 9. f. 4) ; for, being attached

principally to a gigantic Echium closely related to the E. candicans

on which that insect subsists, being exposed, apparently, to much the

same external conditions as its ally, and ornamented with almost

the same colouring, I did not imagine it probable that the small

pntna facie differences which it presented would be anything more

than such as Ave might reasonably look for, as the result of local

influences, in the same species inhabiting islands so separated from

each other as Madeira and Teneriffe. Nevertheless, on a nearer

inspection, the L. persimilis possesses such a number of minor cha-

racters peculiarly its own, that I cannot feel justified, despite the

many points of resemblance in the two insects, in regarding them as

otherwise than truly distinct, though clearly members of the same

geographical province. The Canarian species may be readily known

from the Madeiran one by its uniformly smaller size, rather shorter

and more lunulate pro thorax (which is a little more truncated in

front, and has the hinder angles more rounded -off, and the sides

somewhat more angulated in the middle), and by its entire sculpture,

which is denser and very much more coarse, especially on the elytra

(which are also more evidently striated than is the case in the

L. Masoni). Its elytra also are slightly more truncated at their

apex, its whole surface much less opake, and its coloration is alto-

gether a little different, — its head being less black, or more piceous,

its pro thorax more evidently rafo -testaceous, its legs and elytra not

quite so pale, and the dark portions of the latter smaller in size ;

i. e. the humeral and discal patches are, both of them, reduced in

dimensions, and the sutural line is equal throughout, being scarcely

(if at all) expanded posteriorly, whereas in the L. Masoni it is regu-

larly hastate or spear-shaped. Its limbs, moreover, are shorter and

less robust. It seems almost confined to the foliage of a large

6 Mr. T. V. Wollaston on the Halticidte of the Canary Islands.

Echium (which the Rev. K. T. Lowe informs me is probably the

E. simplex), much resembling, in general growth and aspect, the

Madeiran E. candicans, on which I have taken it abundantly at the

foot of the Organo rocks in the sylvan region above the Agua Mansa,

of Teneriife, nearly 5000 feet above the sea. It does occasionally,

however, occur on other and smaller plants of the same genus, on

one of which (I believe the E. violaceum) I captured it, during

February of 1849, on the hills to the west of Valverde, in the island

of Hierro.

inde vulgaris.

It is not without some little hesitation that I regard the present

Longitarsus as distinct from the preceding one ; nevertheless, since

its normal fades is very dissimilar, and its habits different, I think

it is scarcely safe to amalgamate the two. Indeed, in its general

aspect it is so unlike the L. persimilis, that no one could ever suppose

them to be identical, did not an occasional (though very rare) variety

of the present insect make such a curious approach, in the arrange-

ment of its colouring, to its ally, as to lead one to suspect that it may

be but a phasis of the latter, gradually assumed through the adoption

of a totally different plant for its subsistence. Still this is but con-

jecture, and I therefore prefer treating the two as separate. In its

typical state, the L. Messerschmidtice is, on the average, a trifle

smaller and narrower than its ally, its sculpture is less deep, and it

is of a uniformly pale, brownish-testaceous hue. Its elytra, how-

ever (in which case the apex of its posterior femora are also dark),

have an occasional tendency to become clouded about their disk,

suture, and shoulders ; and in one or two highly coloured specimens

(out of many hundreds which I possess) the discal cloud assumes

the form of a small well-defined patch (and even the humeral one is

somewhat concentrated), — thus causing them to resemble very much

the paler examples of the L. persim'dis. Such individuals, however,

are extremely scarce ; and even in them the lighter sculpture pre-

vails (as in the ordinary ones) ; and therefore, in spite of their prima

facie approach to the last species, I must regard their connectiv, ness

as more apparent than real. So far as I have hitherto observed, the

Mr. T. V. Wollaston on the Haltioidae of the Canary Islands. 7

present Longitarsus is exclusively attached to the fragrant Alesser-

schmidtia fruticosa, — on which shrub, when carefully examined, I

have scarcely ever failed to detect it. Its range is consequently

somewhat lower than that of the L. persimilis, which feeds on the

Echia of more lofty elevations. I have taken it abundantly in the

waste grounds above the Puerto of Orotava, as well as between Ycod

de los Vinhos and Garachico, of Teneriffe ; on rocks between the

plains of los Llanos and the Pinal, in the Banda, of Palma ; and a

little above the sea- coast, in the district of El Golfo, to the west of

Hierro.

The common European L. ochroleucus appears to be somewhat

scarce, or at any rate extremely local, in the Canaries, and may

perhaps have been introduced into the islands. I have taken it

sparingly near Santa Cruz in Teneriffe ; and, more abundantly, in

Grand Canary, where, during April 1858, it was rather plentiful on

the mountain-slopes above San Martao, on the ascent to the Roca

del Soucilho.

The single specimen, from which I have drawn out the above

description, was detected by John Gray, Esq., near Port Cabras, in

the island of Fuerteventura, during our sojourn there, in his yacht,

at the end of January 1858. It is a good deal allied, at first sight,

to the common European L. tabidus, but is smaller and of a more

pallid hue, and with its hind femora dark. Its antenna? also are

slenderer ; its prothorax shorter, more truncated in front, and less

margined at the edges ; and its punctuation is altogether very much

finer.

Like the last species, the present one has been also described from

a unique example. It was captured, by myself, from off a plant of

the Heliophytum erosion, Lemann, on the sands behind the sea-beach

to the south of Arrecife, in the island of Lanzarote, during April

1859. There were three more specimens in company with it, but I

unfortunately failed in securing them. It is apparently akin to the

L. atricajpiUus, Dufts., of more northern latitudes ; and M. Allard, of

Paris, to whom I lately submitted it for inspection, returned it with

the observation : " affinis Teinodactyla atricapillce, Dufts., sed aliter

A single specimen of the Madeiran L. nubigena was captured by

John Gray, Esq., near San Sebastian, in Goniera, during our visit to

that island at the beginning of February 1858. It is a trifle larger

than any of the few examples which I have hitherto taken in

Madeira ; but in all other particulars (such as colour, outline, sculp-

ture, tfcc.) it agrees with them precisely.

places around Haria (especially, I think, from off the Mercurialis

it in the same locality during March of the following year. But it

is the only region in which I have hitherto observed it throughout

the Canarian group.

The single specimen described above was captured by myself, at

the beginning of May 1859, in Teneriffe, on the mountain-slopes

midway between the Agua Mansa and the Cumbre, more than 5000

feet above the sea. It very much resembles the European L. thora-

cicus, Steph., of which it may perhaps be but a geographical state ;

nevertheless, since M. Allard, to whom I lately transmitted it for

inspection, believes it to be distinct therefrom, I have treated it

accordingly. It seems to differ principally from that species in its

smaller size and larger punctuation.

1857, under the name of L. excurvus, from specimens detected in

Porto Santa by Mr. Bewicke.

The P. hospes abounds at low and intermediate elevations through-

out the Canarian Group, on the whole seven islands of which I have

taken it in greater or less profusion ; and it was also captured in

Lanzarote, Gomera, and Hierro by Mr. Gray. In the Madeiras also,

though less common, it is nearly (if not quite) universal, having been

observed by myself in Madeira proper, in Porto Santo, and on the

Dezerta Grande ; so that it may be properly regarded as an Atlantic

species. It is the representative of the P. cuprea of more northern

latitudes ; and M. Allard, to whose examination I have lately sub-

mitted it, returned it with the remark : " Psyll. cuprece, 111., affinis,

Like the last species, the present one abounds throughout the

Canarian archipelago, Gomera being the only island on which I have

not hitherto captured it ; nevertheless there can be no doubt that it

exists there, no less than on the others, — our short visit to that

island happening to be during the depth of winter, when the Halti-

cidce are not plentiful. It was taken also by Mr. Gray in Fuerte-

ventura and Palma. It is equally common likewise in the neigh-

bouring group, where I have observed it, in profusion, at nearly all

elevations in Madeira proper, as well as in Porto Santo and on the

Dezerta Grande.

The small, convex, seneo-piceous Psylliodes described above, the

head of which is much deflexed, and the prothorax (in addition to

its shallow punctures) minutely alutaceous, is tolerably abundant in

certain parts of Lanzarote and Fuerteventura, — in the former of

Avhich islands it was taken both by Mr. Gray and myself, on the

common Mercurial is annua, in the vicinity of Haria, during January

1858 ; and in the latter, by myself, at Oliva, towards the end of

March of the following year.

The general aspect of the present Chcetoenema is almost the same

as that of the common European C. aridella, except that it is a little

more aeneous and shining, that the prothorax is somewhat more

truncated (or less produced behind), and that the intermediate joints

of the antennae are rather slenderer ; and it was not until closely over-

hauling it that I detected a structural character which at once sepa-

rated it from its more northern ally. This consists in the formation

of the tarsi, which are very much narrower and more elongated than

those of the C. aridella, with their apical joint especially (as com-

pared with the corresponding one in that species) long and slender.

The penultimate one also is less dilated than is the case in that

insect, and the whole foot has a different appearance. It was detected

by myself, on the 14th of April, 1858, at Argeniguin, in the south

II. — Remarks on the PoUinosity of the Genera Lixus and Larinus.

By Henri Jekel, Member of the Entomological Society of France,

&c. &c.

The following paper, the manuscript of which was delivered to Mr.

White, of the British Museum, in January 1859, together with cer-

tain remarks on two species of Larinus, for Mr. Daniel Hanbury, to

accompany his note on the products of these two species*, has not

(from a misunderstanding on my part '?) been added to that note, but

was returned to me a few weeks ago by Mr. White. 1 had under-

stood Mr. Hanbury desired me, besides determining the two species,

to give a general account of the authors who had treated on the

habits of that genus ; hence the few remarks which 1 now beg for

acceptance in this Journal, hoping they will not be devoid of interest.

With respect to the tomentosity and pollinose transudation of Liocus

and Larinus, I think it will not be out of place to mention here a

fact until now overlooked, so far as I know. It appears to me, from

long observation of the covering adorning many Curculionideous

Beetles, that Nature acts, in clothing them, by layers or coatings.

There is, immediately above the derm of the elytra and thorax, ;i

thin tomentosc squamosity, either more or less piliform and opake,

or very fine, silky, and bright. This ground-layer, common to many

other tomentosc Coleoptera, is comparatively persistent, though far

more easily rubbed oft' than setiibrm or hairy pilosity, and is analogous

to the squamosity of species having one layer only. This tomentosity

is not produced by exudation, but grows according to the general

law, is susceptible of partial or total baldness, as in merely squamose

insects, and if rubbed oft, when the insect is alive, woidd be restored

in course of time only. Then comes the second layer, much less

persistent (even in non-pollinose species t), which in the above two

genera, as in many others, is a real pollinose transudation, suscep-

tible of a relatively immediate renewal when rubbed off the living

insect. Of this upper layer 1 need not remark, after the con-

scientious observations of M. (Wart, the highly interesting contro-

* " Note on two Insect-products from Persia," in Journ. Proceed. Linn. Soc.

lii. p. 178(1855)).

t See mv analogous observations in ' Fabricia Entomologica,' i. 154.

M. H. Jekel on the Pollinosity of the Genera Lixus and Larinus. 13

versies of MM. Coquerel and Laboulbene, and the experience of M.

Rojas*, all recorded in the ' Annales de la Societe Entomologique de

France,' 1851-1857.

Hence the results in pollinose species are these : specimens may

have their pollinosity more or less rubbed off, and show underneath

part of the ground squamose tomentosity ; others may be completely

deprived of that pollinose efflorescence, and show the ground tomen-

tosity only ; finally, others, still more rubbed, show only a portion of

the latter, &c. Any entomologist, therefore, in describing either

squamose, tomentose, or pollinose species, should not content him-

self with the description of so variable a substance only, but note

also if there is another layer beneath it, and, in fine, should lay

bare the derm in order to display its characters.

Exclusive of hair or pile, to which (like naked Coleoptera) squamose,

tomentose, or pollinose species are Liable, one might divide them,

according to the composition of their clothing, as follows : —

1. Col. Monolepida : having a single layer of squamosity or tomen-

tosity, with or without denser markings.

* One of M. Rqjas's observations bears on a species of Lixus, inhabiting Vene-

zuela, that I called L. vittatus in lift., intending to describe it in its proper place in

' Insecta Saundersiana.' I think it now preferable to profit by this opportunity to

give a complete diagnosis of the species, and change its name, 1st, in honour of

that zealous entomologist ; 2ndly, because, as that gentleman observes, very fresh

specimens are so densely covered with sulphureo-ochraceous pollinose dust,

and others, entirely rubbed off, are so completely destitute of it, that the vitta

are hardly discernible.

2. Col. Dilepida: having two layers of squamosity or tonientosity.

one inferior, with or without denser markings, generally of a

pale unicolor hue (grey, ashy, or whitish) ; the other supe-

rior, less persistent, easier rubbed off, increasing or modifying

the coloration of the markings, when they exist, and filling

more or less the areas between the markings.

3. Col. Paipahpida : ground -layer tomentose, following the same

laws as in class 2 ; but superior layer being a pollinosc trans-

udation, more or less deeply colouring the ground, as well as

the ground-marldngs, when they exist.

To complete the various modes in which the derm of

Coleoptera presents itself to the eye of the entomologist, the

naked species (always exclusive of hair or pile) should form

the fourth class (or rather the first of all), viz., —

4. Col. Alepida.

As a supplement to the above observations, it will not be super-

fluous, I hope, to give a summary list of the principal species of

Larinus, whose habitat, food, even larva state and metamorphoses,

have been recorded by various authors ; a stimulus, I think, to

further researches on the part of such entomologists as may be in

the condition of making so desirable investigations.

III. — Characters of undescribed Species of the Genus Leucospis.

By F. Walker, F.L.S.

The Leucospidce are very distinct from the other families of Chalci-

dites, and appear to be nearly as much allied to the Cynipites, and

to connect the two tribes.

In New Caledonia they are represented by L. antiqua ; in the Aru

Islands by L. Aruera and Aruina ; in China by L. Sinensis ; in Hin-

dostan by L. atra, petiolata, and Quzeratensis ; in South Africa by

L. ornata and incarnata; in West Africa by Mdrres dicomas; in

North Africa by L. brevicauda, Fabric! i. and Algirica ; in Egypt by

L. miniata, frenata, scutellata, obsoleta, and intermedia ; in Arabia by

L. elegans ; in Tauria by L. aculeata and gibba ; in South Europe by

L. grandis, gigas, nigricornis, intermedia, Spinola?, varia, Biguetina,

dorsigera, rufonotata, clavata, Orohmanni, assimilis, and Sicelis ; in

Canada by L. Canadensis ; in the United States by L. Shuchtrdi,

subnotata, and basalis ; in Mexico by L. Klugii and Mexicana ; in

the West Indies by L. Cayennensis ; in South America by L. Hopei,

Caycnnensis, leucotehts, Santarema, Egaia. Tap>ayosa, and speifera,

and by Polistomorpha Surinamensis and sphegoides.

It thus appears that the Mediterranean region is their chief habi-

tation, and there they have their most characteristic form, which is

more or less modified in several other districts.

In North America and in China there is no alteration of the

of the Genus Leucospis. 17

typical structure ; in Hindostan the species, as represented by L.

atra, hardly differ from the Mediterranean type, except in colour,

and the same may be said of L. ornata in South Africa. In West

Africa the only one known species is very peculiar, and in Aru

Island the species differ less from those of Europe than in New

Caledonia ; but the greatest variation occurs in Mexico, in the West

Indies, and in South America, and the principal group in the latter

continent may be divided into at least four subgroups. One of these

has been named Metallopsis, but is hardly sufficiently different from

Leucospis. Polistomorpha forms a very distinct genus.

IV. — Descriptions of New Genera and Species of Eumolpidae.

By J. S. Baly,

The chaotic state of the Eamolpidie, the crowd of species which

remain unnamed and unarranged in our collections, and the want of

generic landmarks, have induced me to select some of the more

interesting for description, proposing in many instances new genera,

of which I have briefly given the differential characters.

Genus Basilepta.

Caput exsertum, facie subelongata, fere perpendiculare ; oculis prominen-

tibus, rotundatis, integris ; antennis gracilibus, filiformibus, corpore lon-

gioribus, articulo tertio quarto fere dimidio breviori ; pcdpis maxillaribus

subfiliformibus, articulo ultimo angustato-ovato, ad apicem attenuate

Tlwrax lateribus marginatis, pone medium angulatis ; antepectoris seg-

mento antero-laterali (fig. 1 b) cuneiformi, apice acuto, angulo exteriori

ad thoracis angulum anticimi extenso. ScuteUum subtrigonatum, apice

obtusum. Elytra thorace latiora, oblonga, modice convexa. Pedes

elongati, graciles; femoribus dimidio basali attenuatis, filiformibus,

dimidio apicali incrassatis, ampullatis, quatuor posticis subtus ante

apicem dente acuto armatis ; tibiis gracilibus, extus ante apicem emar-

ginatis ; tarsis (fig. 1 d) gracilibus, articulo primo duobus sequentibus

aiquali ; unguicido (fig. 1 c) basi appendiculato.

Type, Basilepta longipes, Baly.

Basilepta longipes. (Plate I. fig. 1.)

B. subelongata, valde convexa, nitida, supra obscure viridi-senea ; pedibus

elytrorumque tuberculo obscure piceis, corpore subtus antennisque (his

basi fulva exceptis) nigro-piceis ; thorace lateribus angidato. — Long.

2 1in.

Subelongate, very convex, nitidous, above obscure metallic green,

body beneath and the antennae (the fulvous base of these latter excepted)

obscure pitchy-black ; a large shining circular protuberance on the

basilar space of each elytron, together with the legs, piceous ; attenuated

base of four posterior thighs obscure fulvous. Head smooth above,

forehead with a longitudinal groove ; lower portion of face deeply

punctured ; antenna? slender, filiform, longer than the body, three basal

24 Mr. J. 8. Baly on t/a Kumolphhe.

joints obscure fulvous. Thorax rather longer than broad; sides pro-

duced mid angled just behind their middle, their hinder portion sinuate ;

above transverse, convex, gradually thickened and gibbose towards the

apex : sui face deeply rugose-punctate, interstices irregularly thickened ;

gibbose portion nearly impunctate. Scutellum subtrigonate. Elytra

much broader at the base than the thorax, nearly three times the length,

slightly narrowed behind, convex; each elytron with eleven rows of

distinct punctate striae, the first abbreviated; on the posterior half

of the elytra nearly all the stria' become obsolete, whilst on the epi-

pleura are two short additional rows, making the total number across

that portion of the surface thirteen ; humeral callus elevated into a

short compressed ridge; on the basilar space, between the humeral

callus and tin 'suture, is a distinctly raised circular piceous protuberance,

its circumference bounded by an indistinct circular groove, the surface

of the protuberance smooth and shining, impunctate. Body beneath

obscure nigro-piceous ; legs piceous, elongate, basal half of thighs

slender, filiform, apical half flask-shaped, two posterior pairs armed

towards their apex beneath with a tine acute tooth, basal half of the

same thighs obscure fulvous ; all the legs sparingly covered with long

silky hairs.

Hah. Borneo.

This insect, most remarkable from its slender, spider-like legs,

has been sent in some abundance from the above-mentioned locality

by Mr. Wallace.

Genus Si'ii-oi'YKA.

Caput exsertum, modice deilexum ; ocuUs prominulis, oblongo-ovatis, intus

obsolete sinuatis ; antennis modice robustis, subiiliformibus, articulo

secundo obconico, tertio illo duplo longiori, articulo sequent! paullo

breviori, quinque ultimis vix incrassatis ; palpis maxiUaribtu (fig. 3 m)

articulo ultimo ovato, ad apicem attenuate. Thorax transversa?, ante-

pectoris segmento antero-laterali (fig. 8 6) brevi, transverso. Scutellum

trigonatum, apice ohtusum. Elytra oblonga, postice paidlo attenuata,

convexa, ante medium gibbosa. Pedes robusti, subelongati, antici ceteris

paullo longiores ; tarsis (fig. 3d) articulo tertio bilobato, fere ad basin

divisoj ungue valido, unguiculo (fig. 3 e) simplici, inermi. Prostemum

(fig. 3 f) trapeziforme, elevatum, antice abbreviatum ; mesosternum

i fig. •*''/*) breve, transversum. Corpus oblongo-elongatum, convexum.

Type, SpUopyra sumptuosa, Baly.

This splendid genus, like its near neighbour Fodontia, has quite

the habit of a Chrysomela ; but M. Lacordaire, in the introductory

remarks to his • Monographic des Phytqphages,' having separated

the closely allied families of Chrysomelidce and Eumolpidce by the

deeply bilobed third joint of the tarsi in the latter group, rigidly

exclude^ all insects possessing that character from the former. In

Mr. J. S. Baly on the Euniolpidae. 25

deference therefore to his opinion, I have placed it for the present

amongst the Eumolpidce, although it is so closely connected in other

respects with the true Ohrysomelidce as almost to form a link be-

tween the two groups. In addition to the general form of the body,

the structure of the sternum, and above all, the simple claw (common

to the great majority of Chrysomelidce, but wanting, with this soli-

tary exception, in the Eumolpidce), there is yet another important

differential character, hitherto overlooked, uniting it to the Chry-

somelidce, and which, I believe, will become extremely useful in

separating the two families, — I mean the form of the antero-lateral

plate of the antepectus; this part, in all the Chrysomelidce that I have

as yet examined, is short and transverse, its hinder margin being

entire, and not dilated posteriorly ; in the Eumolpidce (the present

genus and Podontia excepted) the same organ is more or less trigo-

nate or trapezoid, its posterior edge being produced backwards into

an oblong or angular process. This process varies much in shape,

and might often, I think, be made available in determining the

limits of some of the genera in this difficult group of insects.

The simple claw at once divides Spilopyra from Podontia, the only

genus with which it can be confoiuided.

Spilopyra sumptuosa. (Plate I. fig. 3, 3* lateral view.)

S. oblonga, convexa, dorso gibbosa, nitido-metallico-purpurea, violaceo-

base than the thorax; sides nearly parallel, slightly narrowed towards

the apex, the latter acutebj rounded; above convex, obtusely gibbose

below the base; each elytron with thirteen rows of fine punctures, the

first abbreviated, the outer row placed on the extreme lateral border,

interspaces smooth and shining, impunctatej on the surface of each

elytron are placed the following bright metallic green markings, bor-

dered with aureous; viz., two spots at the base, the first elongate,

situated halfway between the humeral callus and the suture, the second

placed mi the humeral angle; an entire, slightly sinuous and deeply-

grooved fascia just before the middle; a short, deeply impressed sub-

sinuous band, situated immediately behind the middle, and extending

from the outer margin more than a third part across the elytron ; an

oblique line commencing at the outer border, halfway between its

middle and apex, and running obliquely upwards nearly to the suture ;

and lastly, a narrow line covering the posterior two-thirds of the

suture itself. Body beneath variegated with bright metallic green and

purplish cupreous ; legs rufous, the knees and tarsi bright metallic green.

dente valido annate. Corpus elongatum, subcylindricum, hirsutum.

Type, Trichotheca hirtll, Baly.

This genus ought to stand close to Adoxus, Kirby ; its elongated

body, slender filiform antennas, and incrassated anterior pair of

femora will separate it from the latter.

V. — Notices of new or little-Tcnoivn Genera and Species of Coleoptera.

By Francis P. Pascoe, F.L.S., &c.

Part I.

It is difficult to form any adequate idea of the number of new forms,

to say nothing of new species of insects, which exist in, or are being

constantly added to, our cabinets*. Many of these are almost hope-

* Mr. S. Stevens has just favoured me with the sight of a collection of Coleo-

ptera (perhaps about a thousand species) made by Mr. Squire at Petropolis (a

sort of Brazilian Cintra, and a short day's journey from Rio), and although

the <list riot has been repeatedly worked, and Mr. Squire was there scarcely two

months, yet the result of his visit has been the discovery of a vast number of

novelties nnd some new. forms of a very interesting character.

lessly entombed in private as well as in public collections, or have

long been accumulating in my own. To record the most remarkable,

and such, at the same time, as can easily be recognized by figures

and descriptions, if confined to a private collection, is one of the

objects of this Journal, and the following is the first of a series of

papers which will be devoted to the Coleoptera. As it will be im-

possible to follow any systematic plan beyond the limits of each

paper, a classified list will be given hereafter to diminish this incon-

venience.

It must not be forgotten that many of the insects to be described

will be either uniques, or, belonging to others, cannot therefore be

mutilated by dissection ; but as every new genus will be figured, it

is hoped that the absence of the usual analyses will not create any

difficulty. Practically, we are satisfied with referring species to

their genera from their external resemblances ; but although it is

very often quite impossible to ascertain the affinities of an insect

without dissection, there is the danger of attaching too great import-

ance to organs whose characters cannot always be determined satis-

factorily, and which, moreover, because they occur in one species,

are sometimes erroneously assumed to be present in others. Indeed,

it may be doubted if even individual species are so invariable as to

justify the minute desci-iptions of many naturalists.

While believing in the existence of genera quite as much as in the

existence of species, is it satisfactorily established that they can

always be distinguished by technical characters, such as we are in

the habit of employing ? In all large genera, I believe, it will be

eventually found that they possess no one character in common that

is not also possessed by the group or family to which they respect-

ively belong, and hence it is quite natural that the limits of such

genera cannot be very strongly defined. This is especially the case

in the Longicorn families, which with endless differences in habit

agree in a certain similarity of details, so that the generic characters

often become mere questions of degree, — while, on the other hand,

many Heteromei'a alike in habit are found to vary remarkably in

structure, and in fact to belong to very different groups than those

in which their general appearance would seem to place them.

These and other points of the same kind will be often exemplified

in the course of these ' Notices ; ' but in considering the difficulties

which beset all attempts at a satisfactory limitation and arrange-

ment of species into families, genera, &c, it will be as well to bear

in mind the remark of our great naturalist. — " Nature is less of a

svstematist than Man."'

For the possession of this and many other Coleoptera from the

same locality, I am indebted to Dr. Ernest Adams of University

College, the author (inter alia) of some exceedingly interesting

and learned papers on the " Vernacular names of Insects," in the

Transactions of the Philological Society, who received them front

India*, where they were collected by Mrs. Brettingham (to whom I

have dedicated the exquisite little Omophron just described) in the

compound attached to the quarters of Charles Brettingham, Esq., in

medical charge of the Kamroop Beginient of Native Infantry sta-

tioned at Dacca. They comprised above seventy species, belonging

to nearly as many genera. Of these there were only six or seven

that were not represented in Europe, viz. Adoretus, Heteronychus,

Anisoteh's, Macratria, a Nitidulid, and two, or perhaps three, obscure

Heteromcrous genera, which I have not been able to refer to any

hitherto published. Except that there were very few Staphylinidae,

they were mostly such forms as would be found in this country in

the debris of a flood ; and it is, therefore, most likely that they

were collected in the rainy season. Dacca is nearly in the latitude

of Calcutta, lies very low, and as it is subject to inundations from

the Ganges, it is probable that it affords a larger proportion of

European forms than would have been the case in a drier or more

elevated district. So little is really known of the Entomology

rally much smaller, enclosed in two large-sized pill-boxes, were transmitted by

available substitute for a box.

of India, that it would be premature to speculate as to its cha-

racter ; but although in its animal productions there is a remark-

able amount of Northern temperate forms, they could never have

been expected to predominate to such an extent in any one group,

as it now appears they do, judging, however, solely from the facts

here stated*. There is one point in connexion with this subject

which can only be just alluded to here, viz. the apparent tendency of

animals to migrate to the south, and not the reverse, or very slightly

sof. The idea first occurred to me in noticing the very few Austra-

lian forms of Coleoptera occurring in Mr. "Wallace's Indian Island

collections contrasted with the number of these Indian forms in

Australia, especially its northern parts ; — compare also Natal with

the Cape, or the United States with Mexico or Cuba ; notice Upper

Egypt, Arabia, Persia, «fec, just receiving a tropical form here and

there.

collection from Dacca, evidently made in a more favourable season ; still, although

there is an addition of many tropical genera, European vastly predominate ; and

it is worth notice, that nearly all these tropical genera have a very wide range, as

for example^ Anthia, Chrysochroa, Protatia, Xylonychus, Cerosterna, Olenocamptus,

Head small, completely retractile within the thorax. Antenna? re-

large, laminate, the second dilated interiorly, the remainder forming a

compacl Babellate mass. Eyes rounded, entire. Mandibles bidentate at

the last joint very large, cylindrical ; the labial claviibrm. Mentum

convex, gibbous towards the base. Legs slender, coxae distant, tarsi

short. Presternum received in a notch of the mesosternum.

These characters are drawn up exclusively from S. Wcstwoodii ;

but the other species so completely resemble it, that there can be no

doubt as to their generic identity. In all, the elytra have nine rows

of punctures on each. The structure of the antennae will be better

comprehended by the figure* than by any description, but owing to

their minuteness, I was unable to detach completely the large basal

joint ; when in repose it appears to act as a valve, closing in entirely

the rest of this organ : all the joints composing the flabellate mass

are what may be called boat-shaped, except the last, each being re-

ceived at its base, and for the greater part of its length, in the con-

cavity of the preceding one, — the first, however, being so much more

dilated as so far to enclose the succeeding or fourth joint, that it is

only visible at its free extremity ; and unless this is attended to, the

antennas will appear to be composed of ten joints only.

I have dedicated the first species to J. 0. Westwood, Esq., M.A.,

F.L.S., ifcc, and have adopted his views respecting the position of

Byrsax [Colydiidae].

Head small, vertical, hidden above by the prothorax. Eves large,

rounded, partially divided by the cheek. Antennae retractile, short,

gradually increasing upwards ; the first joint rather slender, the second

shortest, the third and fourth longest and equal, the fifth triangular,

the sixth to the tenth transverse, the eleventh shortly ovoid. Labrum

and epistome very small. Palpi short, linear, the terminal joint ovate.

[Mentum transverse ; labium oblong, entire, as seen in situ.'] Prothorax

very transverse, gibbous in the middle, bicornuted anteriorly, the mar-

gins dilated and crenulate. Elytra short, very convex, tuberculate,

with broad crenulate margins. Legs of moderate size ; tarsi with the

first three joints veiy short, equal, with fine hairs beneath. Prostemum

strongly compressed. Mesosternum toothed.

In habit this genus closely resembles the Diaperis horrida, 01.,

with which Mr. Walker's Asida horrida is probably identical. Its

real affinity, however, if we are to be guided by the tetramerous

tarsi, is with Endophloeus, Pristoderns, and some other little-known

and even undescribed forms among the Colydiidae, but differing from

all in its head being perfectly hidden by the prothorax when viewed

from above*.

The occurrence of a genus so purely American as Sphasromorphas

in Borneo may well excite surprise, as, a priori, it might have been

supposed, if any of that group occurred at all in the Indian Archi-

pelago, it would have been either a new form, or the Madagascar

Synarmostes. I cannot, however, find, from dissection of S. acromialis,

any variation of character sufficiently marked to warrant its separa-

tion from SphceromorpJius. Dedicated to Mr. A. Wallace, to whose

researches in the Indian Archipelago we owe so much.

Cormodes [Cleridse].

Head rather short, broad in front. Eyes ovate, vertical, scarcely emar-

ginate. Antennas as long as the thorax, arising laterally in front of the

eyes, 11-jointed, the first largest, the second shorter than the third,

the last three forming a slender pointed club. Palpi with the terminal

joint of the labial securiform, of the maxillary cylindrical. Labrum

small, hairy. Prothorax subdepressed, rounded in front and at the

sides, contracted posteriorly, — the pronotum confounded with the para-

pleura. Scutellum transverse. Elytra depressed, narrowed at the base,

gradually expanding at the sides, with a strongly marked carina at the

shoulder, but no humeral angle. Wings none. Legs stout, femora

clavate, tibioe and tarsi short, the first tarsal joint nearly covered above

by the second ; claws simple. Abdomen of five segments.

Although very dissimilar in habit to the Cleridas in general, there

is no doubt that this genus is closely allied to Natalis. It is, I

believe, the only one of its family without wings, — a condition due,

as Mr. Darwin tells us, in reference to other insular apterous Co-

leoptera, to " the action of natural selection, but combined probably

with disuse," and therefore it would not, perhaps, be very difiicult

for the advocates of his theory to suppose Cormodes a descendant of

Natalis, to which it certainly bears a very peculiar resemblance.

The absence of a real humeral angle, but its simulation by an ele-

vated and narrow carina (absent in all other Cleridoe), and the, in

other respects, well-developed elytra, do not appear to lead to the

conclusion of the gradual reduction of the wings which such an ex-

planation implies, because corresponding with this presumed reduc-

tion we have an unaccountable and apparently unnecessary increase

of the elytra, combined, however, with the absorption of the humeral

angle. I possess a Longicorn, closely allied to Mr. Wollaston's oceanic

genus Deucalion, also without humeral angles, but having perfect,

although excessively small, wings, and of course entirely useless for

the purpose of flight ; but in this case the wings might at any time

disappear from physical causes alone, just as we find certain species

of Hemiptera becoming apterous in cold localities or in very cold

seasons. In these and other instances of abnormal variation, which

in almost every case seem to have some speciality of their own, we

look in vain for the " advantage " which is supposed to have been

acquired in the " struggle for life." An insect so suggestive of Mr.

Darwin's theory should appropriately bear his name.

Aulicus instabilis, Newm., the type of the genus, is such a variable

insect, that it is quite possible this may be but one of its protean

forms ; nevertheless, besides its smaller size, it is more convex, the

prothorax narrower and less depressed, its greatest breadth being

behind the middle, and the posterior and anterior margins being

nearly equal; its head is also shorter, the eyes proportionally larger,

and the antennas longer ; moreover I have never seen any specimen

of A. instabilis approaching this in colour.

Choeesine [Cleridae].

Head small, transversely triangular in front, slightly exserted behind.

Eyes rounded, prominent, entire. Antenna? 11-jointed, linear, not half

the length of the body, arising in front of the eyes; the first joint twice

as long as the second, which is only a little shorter than the third, the

fourth and fifth slightly longer, the rest subequal. Labrum transverse,

entire. Mandibles strongly curved, bidentate at the apex. Palpi clavi-

form, the joints very short and transverse, the maxillary much larger

than the labial. Maxilla? rounded, two-lobed. Labium obovate. Pro-

thorax subquadrate, constricted posteriorly before the base ; pronotum

distinct from the parapleura?. Scutellum small, triangular. Elytra

convex, nearly hemispherical, advancing at their insertion on the base

of the prothorax. Legs slender; first joint of the anterior tarsi nearly

covered by the second above ; the middle and posterior tarsi with all

the joints free, the three intermediate of all furnished with lamella?.

Abdomen slender, of six ? segments.

The habit of this very remarkable insect approaches in some

respects the Melyrideous genus Chalcas ; the structure of the tarsi,

however, is that of a Clerid, and although a very isolated form, I see

no difficulty in placing it in the subfamily Enopliina?.

maxillary with its terminal joint subsecuriform. Maxillae two-lobed, the

lobes ciliated (the inner armed* ?). Prothorax depressed, contracted

behind, broadly emarginate in front, its anterior angles roimded. Elytra

very depressed, parallel, abruptly bent down at the sides ; the epipleural

plait narrow, terminating before reaching the apex. Legs short ; coxae

distant ; tibiae spurred, the anterior serrated externally ; tarsi slender,

the first joint of the posterior as long as the last. Pro- and mesosterna

broad and flat, the former rounded posteriorly, and received into a slight

emargination of the mesosternum.

A remarkable genus, which might readily be taken for a Pla-

tisus, but which is very closely allied to, if not identical with,

Mr. "Wollaston's Adelina. As, however, the characters of his genus

were drawn up from an insect which he suspects may not be con-

generic with certain representatives in the British Museum of

M. Chevrolat's original, but unpublished Adelina (but which unques-

tionably includes the species now to be described), and his detailed

description differs in several, although somewhat secondary points,

from that given above, and he has taken no notice of the peculiar

elytra, I have thought it better to consider my species the type

of another group ; and I do so with less hesitation, as the name of

Adelina has been long preoccupied by a genus of Gasteropods.

Doliema, thus restricted, has a remarkable range, D. platisoides oc-

curring in Ceylon, Manilla, and the Moluccas, while a closely-allied

species, differing in nothing apparently but in having a somewhat

broader head, is found in the valley of the Amazons.

Stilpnonotus eurypiformis (named, but not described, by Mr. G. R.

Gray in the English edition of the ' Regne Animal ') appears to me

to be referable to Mr. Kirby's Eurypus, a genus not alluded to by

M. Lacordaire in his great work. Mr. Kirby's species, E. rubens,

from the figure, seems to be a much broader insect than the present,

which it is not impossible may be identical with Olivier's Tenebrio

nitens. The pronotum is confounded with the parapleurae, and the

anterior coxa? are contiguous and greatly exserted, two characters

which do not accord well with the Tenebrionidae : the possession of

antennary orbits forbids its association with Lagriidae. In habit it

is slightly assimilated to Camaria.

transverse. Prothorax subquadrate, posterior angle emarginate, the

parapleural distinct. Elytra as broad as the thorax, tapering posteriorly,

the epipleural plait very narrow. Legs short ; anterior coxa? conical,

contiguous, their acetabula closed behind, the intermediate subapproxi-

mate, oblique, furnished with trochanters, the posterior transverse ;

tibise spurred; tarsi very slender, the first joint long, the penultimate

entire ; claws simple. Mesosternum narrow, truncate behind.

Genera and Species of Coleoptera. 53

I have not placed this genus among the Melandryidae without

hesitation, on account of its antennary orbits, and its acetabula

closed behind ; on the other hand, its parapleural, distinct from the

pronotum, make its location in any other family still more difficult.

Except the comparative shortness of the maxillary palpi, it agrees

•with the Melandryidae in most of the characters given by M. Lacor-

daire, according also in form with some of its genera, without, how-

ever, being related to any of them. Like Tetratoma, it has the

antennae terminating in a club, but only composed of three joints.

In the drawing the maxillary lobes are much too large, compared to

their palpus.

Elacatis delusa. (PI. II. fig. 5.)

E. griseo-testacea, punctulata ; elytris fasciis tribus dentatis, maculaque

basali nigris.

Hah. Borneo (Sarawak) ; New Guinea (Dorey).

Greyish-testaceous, finely punctured, a short setulose hair arising

from each puncture ; prothorax with three or four very minute teeth at

the side, and a shallow transverse impression near the base ; scutellum

long and narrow ; elytra with three black, toothed bands, the first often

interrupted or replaced by a few spots ; a patch of the same colour, also

sometimes broken up into spots, at the base near the scutellum ;

antennae and legs testaceous-yellow, more or less clouded with brown ;

body beneath ferruginous, slightly tomentose. Length l£-2 lines.

My New Guinea specimen agrees perfectly well with those from

Borneo ; but they all vary a little in colour, some being darker than

others, and the black band and scutellar patch being more or less

interrupted. A second species, and a much finer one, from the

Moluccas, is in the collection of W. W. Saunders, Esq.

Biophida [Melandryidae?].

Head moderately long, tumid in front, suddenly contracted behind into a

narrow neck. Eyes distant, lateral, renifomi. Antennas arising close

to the eye, filiform, half as long as the body, 11-jointed; the second

very short, the rest subequal. Labruni transverse, inserted below the

line of the front. Labial palpi filiform ; the maxillary elongate, with

the last joint narrowly securiform. Prothorax depressed, semicircular,

as wide as the elytra behind, its parapleurae distinct. Elytra depressed,

rather broader behind. Legs moderate ; anterior and middle coxae con-

tiguous, the former conical and elongate ; tibiae spurred ; tarsi slender,

the first joint of the four posterior as long or longer than the rest

together, the penultimate bilobed ; claws undivided, strongly toothed

beneath.

This is another of those puzzling genera, of which there are so

54 Mr. F. P. Pascoe on some new or little-known

many among the Heteromera ; in its habit it resembles Scraptia ; but

as the more important characters are those of Melandryidae, and that

family is also one which contains several anomalous forms, it seems

less objectionable to place it in that group than in any other.

Biophida unicolor. (PL III. fig. 4.)

B. fulvo-testacea, pube pallidiori vestita ; prothorace bifoveolato ; oculis

fere concoloribus.

Hab. Natal.

Entirely of a light-brownish testaceous colour, rather closely covered

with short stiffish paler hairs ; a large fovea on each side of the pro-

thorax near the posterior angle ; scutellum transverse, rounded behind ;

eyes a little darker. Length 4 lines.

Ischalia [Pedilidae ?].

Head small, contracted behind, and narrowed anteriorly below the eyes.

Antennae shorter than the body, linear, 11-jointed; second joint smallest,

the rest subequal. Eyes reniform. Epistome and labruni large, covering

the mandibles. Maxillary palpi robust, the last joint securiform ; labial

much shorter, terminating in a broad triangular joint. Maxillae short,

obtuse. Prothorax narrowed anteriorly, irregular above, its posterior

angles produced, the epipleurae confounded with the pronotum. Elytra

broader than the prothorax, subparallel, bent at the side, and concave

on the disc, the epipleural plait narrow. Legs moderate, anterior

acetabula open behind; all the coxae approximate, the anterior and

intermediate conical; tibiae unarmed; tarsi short, first joint longer

than the rest together, the penultimate bilobed ; claws simple.

I refer this genus doubtfully to Pcdilidae, notwithstanding that it

agrees in two characters which M. Lacordaire considers of high im-

portance, viz. the anterior acetabula largely open behind, and the

complete contiguity of the posterior coxse. The family, however, as

it stands at present, is not a satisfactory one, and its learned pro-

poser will probably see reasons for modifying it eventually.

Ischalia indigacea. (PI. III. fig. 6.)

J. cyaneo-violacea; an tennis pedibusque nigris, illis articulis tribus ultimis

Hab. Borneo.

Deep violet-blue ; head and prothorax very minutely punctured

(scarcely visible under a strong lens), the latter more or less irregular ;

scutellum small, triangular ; elytra coarsely punctured, rich violet-blue ;

antennae black, with the last three joints white ; legs black ; body beneath

black, with a slight bluish tinge on the breast. Length 3-4 lines.

The irregularity of the surface of the prothorax varies ; in extreme

cases it has the appearance of being shrivelled up by desiccation.

The structure of the palpi and maxillae will be seen in the figures ;

the labium and men turn unfortunately disappeared in dissection.

Dark brown, sparingly covered with a pale golden-yellow pile ; head

and prothorax finely punctured, the latter with the sides posteriorly

nearly parallel; scutellum small, subtriangular ; elytra very thickly

punctiu-ed *, with a larger series of punctures arranged in closely set

rows, which are divergent at the base ; antennae and palpi tawny, the

former, except three or four of the basal joints, gradually becoming

darker; legs dark brown; the tarsi, except the basal joint of the pos-

terior, yellowish. Length 3 lines.

Macratria fulvipes.

M. nigra ; pedibus (tibiis posticis exceptis), palpis antennisque fulvis, his

Hub. Macassar.

Black, very sparingly covered with a pale golden-yellow pile ; head

and prothorax rather coarsely punctured, the latter with the sides gra-

dually but very slightly contracting posteriorly ; scutellum large, sub-

quadrate ; elytra finely punctured, a larger series in rows as in the last

species ; legs (except the posterior tibiae), palpi, and antennae tawny-

yellow, the latter with the three or four terminal joints darker. Length

head and prothorax slightly punctured, the latter somewhat ovate;

scutellum indistinct; elytra punctured as in the last species, but with the

pile more confined to the rows of punctures ; antennae, palpi, and four

anterior legs pale testaceous ; the posterior femora, except at the base,

tibiae at the base and apex, and basal joints of the tarsi, dark brown or

nearly black ; head tawny-yellow. Length 2} lines.

Hub. India (Dacca).

Light reddish-brown, with a pale greyish pile ; head and prothorax

•very finely punctured, the latter rather broad and somewhat ovate ;

scutellum subtransverse ; elytra punctured, &c, as in the preceding ; legs

(except the posterior pair), palpi, and antennae fulvous, the latter with

the last three joints dark brown ; head and hind legs black, except the

extremity of the tarsi, which are pale yellow. The claws in this species

appear to be broadly toothed at their base. Length 2^ lines.

Macratria subguttata.

M. atra, nitida, sparse albo-hirta ;' elytris, singulo maculis duabus, fere ob-

Hab. Moluccas (Batchian).

Glossy black, with much-dispersed whitish hairs ; each elytron with

two rather indistinct white or somewhat ashy spots, one a little before

the middle, the other the same distance beyond it ; antennae, palpi, and

mouth pale yellow, the former gradually deepening towards the apex

into black; tarsi pale yellowish, except the first joint of the posterior

pair. Length 3 lines.

Emydodes [Lagriidae].

Head very small, rounded behind the eyes, then contracting into a neck,

which is nearly immersed in the prothorax. Eyes large, oblong, emar-

ginate, transverse, and approximating both above and beneath. Labial

palpi very small ; maxillary elongate, the terminal joint ovate, pointed.

Antennas robust, shorter than the body, arising close to the eye, the

first joint tumid, the second very short, the third to the tenth thick,

triangular, with a bifid prolongation at the apex of each on one side,

the eleventh elongate-ovate. Prothorax slightly transverse, rounded

anteriorly, twice the breadth of the head, but much narrower at the

base than the elytra, its parapleurae confounded with the pronotum.

Elytra depressed, with a subovate outline, the epipleura strongly bent in

beneath. Legs robust ; anterior coxae large, approximate, shortly cylin-

drical ; tibiae not spurred, the four posterior thickened in the middle ;

tarsi short, the penultimate joint subbilobed; claws undivided, slightly

toothed at the base.

A very curious genus, which, if rightly referred to Lagriidae (and of

this I have little doubt), differs entirely in the remarkable structure

of the antennae, in which it somewhat resembles the Pyrochroidae.

From my solitary specimen, I cannot make sure that the anterior

acetabula are closed ; they appear to be so, however. As far as I

can judge from the parts in situ, the menturn is subtriangular and

the labium obcordate.

Emydodes collaris. (PI. III. fig. 3.)

E. nigra, setoso-hirsuta ; capite prothoraceque luteis.

Hah. Brazil (Para).

Black, covered with short stiff hairs ; head dull reddish-yellow ;

prothorax thickly punctured, clear reddish-yellow; elytra coarsely

punctured, each in ten rows ; tibiae with long stiff hairs. Length 3

lines.

Iodema [Cantharidae].

Head shortly triangular. Eyes round, prominent, entire. Labrum small,

rounded anteriorly. Palpi slender; terminal joint of the labial ovate,

of the maxillary subcylindrical. Antenna? short, linear, the joints

slightly obconic. Prothorax transverse, narrowed in front. Elytra

subdepressed, wider behind ; the sides somewhat concave. Legs slen-

der; tibia? bicalcarate; penultimate joints of all the tarsi small, tri-

angular.

Differs from Cantharis, with which only it is likely to be con-

founded, in the short penultimate joint of its tarsi : the claws appear

to be undivided, from the close application of their two divisions.

Iodema Clarkii. (PI. III. fig. 1.)

I. atra, nitida; elytris violaceis; tarsorum posticorum articulo primo

Hab. Brazil (Organ Mountains).

Head and prothorax deep glossy black, sparingly punctured, especially

the latter; scutellum narrowly triangular; elytra dark violet-blue,

thickly and irregularly punctured ; body beneath and eyes black ; base

of the first joint of the posterior tarsi whitish ; spurs of the middle

tibia?, and all the claws, except at their apices, yellow. Length 4 lines.

I am indebted for my specimen to the Rev. Hamlet Clark, who

took several individuals at Constancia, in the Organ Mountains.

Zonitis [Cantharidae].

Zonitis cyanipennis. (PI. III. fig. 5.)

Z. angustus, glaber, ater ; prothorace, scutello, femoribusque (apice ex-

This has scarcely the habit of any European Zonitis, and still less

of some depressed Australian species, of which the Z. dichroa of Ger-

mar may probably be taken as the type.

Hab. Australia (Moreton Bay).

Subcylindrical, pitchy, with a short dark-brown tomentum mixed

with black, and blotched with pure white ; head shortly ovate, brown,

slightly spotted with white ; protborax subrotund, very convex, thickly

punctured, dark brown, with an irregular, toothed, white, band-like

mark on its anterior margin ; scutellum very small, white ; elytra punc-

tato-striate, the alternate interstices raised and spotted with black, a

large white lunate patch, more or less spotted with brown, extending

longitudinally on the middle of each elytron, with its convexity

towards the suture, and extending externally to its margin, the apex

also with a white patch of the same character ; antennae pitchy-brown,

slightly hairy ; legs brown, annulated with white ; body beneath didl

cinereous, the three middle abdominal segments having on each side an

impressed hairy spot ; mesosternum three-lobed posteriorly. Length

6 lines.

\Vrith this fine species of Ecelonerus I also obtained a specimen of

Dipieza WaterJwusei, Pasc, hitherto only known from Aru, unless

indeed (as I have elsewhere suggested as regards the genus) the

(Edecerus* bipunctatus of M. Montrouzier, from Woodlark Island,

should be identical, in which case it will probably be found to be

very generally distributed in those regions.

believe, as they have been described : —

Smaller and proportionably shorter than D. auricomus, with the

Clothed with short appressed dark brown hairs varied with grey,

which are more or less ashy ; head entirely grey, the rostrum with

a central carina, and a shorter one on each side below the eye ; pro-

thorax with the sides dark brown spotted with grey, the disc with

a central subtriang-ular ashy spot which is abruptly narrowed behind ;

scutellum ashy ; elytra punctato-striate, rather broad, flatly depressed,

suddenly bent down near the apex, the outer posterior angle of each

bituberculate, the depressed portion dark ashy, the sides dark brown,

the alternate interstices with black and pale yellowish-grey spots ;

body beneath yellowish-brown ; legs annulated with dull brown and

pale grey ; eyes pale brown, somewhat lustrous. Length 5 lines.

I have elsewhere mentioned my suspicions that this genus is syno-

nymous with Denclropemon, Schon., and M. Jekel is inclined to take

the same view of it ; as, however, the name was previously used by

Perty, or what will be considered to amount to the same thing —

for his orthography was Dendropcemon — another name must be

adopted, and Nessia having been applied to a group of Saurians, I

have thought a modification of it to Nessiara will be attended with

the least inconvenience. Stenocerus platipennis ! Montrou., is evi-

dently nearly allied to the species just described, and his three other

Stenoceri probably belong likewise to this genus. &. Gamotii, Guer.,

Hah. Moreton Bay.

Elongate, subcylindrical, with a short dark brown tomenturn, slightly

varied with greyish-white ; head shortly ovate, eyes rather large ; pro-

thorax a little longer than wide, varied anteriorly and at the sides

with greyish ; scutellum minute ; elytra punctate-striate, the alternate

interstices raised and spotted with white, the spots a little before, as

well as behind the middle, elongate, forming an indistinct, oblique,

band-like mark ; antennae dark brown ; legs paler, varied with greyish ;

body beneath greyish -brown. Length 3 lines.

This species, together with B. peregrinns and B. ingrains from

Port Essington, described by me in a recent number of the ' Annals

and Magazine of Natural History ' (Dec. 1859, pp. 432, 433), <fec,

differ from B. nitidicutis, Jekel, the type of the genus, in their nar-

rower and more elongate form, and their brown, not ashy, colour.

Dinokhopala [Curculionidae].

Head small, abruptly contracted below the eyes into a short rostrum.

Eyes large, round, prominent. Antennae short, straight, arising close to

the eyes in a cavity formed between them and a short thick process,

twelve-jointed, the first subpyriform, elongate, the second shorter, sub-

cylindrical, the third to the eighth slender, gradually diminishing in

length, the last four forming an ovate compact club. Prothorax sub-

triangular, lobed at the base, narrow anteriorly, irregular above. Elytra

large, much wider than the prothorax at the base, very irregular and

spinous. Anterior and intermediate legs moderate, the femora clavate

and unidentate beneath, each tibia with a single curved spur; the

posterior longer, their femora slender at the base, abruptly clavate at

the apex, and armed with a strong tooth, their tibiae strongly com-

pressed and curved; the tarsi of all short, the penultimate joints

broadly lobed ; claws toothed beneath ; anterior coxae approximate,

intermediate and posterior widely apart. Meso- and metasterna very

large.

The affinity of this genus is no doubt with Tachygonus, and judging

from its posterior legs, it is probably also saltatorial. As the import-

62 Mr. F. P. Pascoe on some new or little-known

ance of the geniculation of the antennas is now only recognized as a

secondary character, I think M. Jekel* has done good service in

referring all the groups of Schonherr's Orthocerati, after eliminating

those which evidently belonged to the true Curculionidae, to four

families. Taehygonus is one of the genera so removed, and this

M. Jekel seems inclined to place near Ceutorhynchus.

The figure, which is in no degree exaggerated, will give a better

tion. It was taken, with other very interesting species, by an

duced; legs dark brown, the basal portions of the femora and tibiae

reddish-testaceous ; antennae longer than the body, slightly setose, red-

dish-brown, the apices of the intermediate joints black; body beneath

reddish-brown. Length 5 lines.

From the slender and elongated tarsi, particularly the posterior, I

should be inclined to refer this genus to the neighbourhood of

(Edopeza, rather than to Monohammus, where formerly I had doubt-

fully placed it. Except the slightest possible variation in the patches

on the elytra, there appears to be no difference between the Batchian

and Dory insects.

thorax anteriorly); legs glossy ferruginous, femora at the apex and

tarsi dark brown or nearly black ; body beneath smooth, brownish,

VI. — Descriptions of new Genera and Species of Exotic Hyruenoptera.

By Frederick Smith, Esq., Assistant in the Zoological Depart-

ment of the British Museum.

Since the publication of the ' Catalogue of the Formicidce/ in 1858,

I have described nearly two hundred new species belonging to that

family, the whole being inhabitants of the Eastern Archipelago. I

have not described, since the above period, any Ants from other

localities; the consequence has been, that many interesting and

some remarkable species have accumulated which are new to science ;

a portion of these I purpose describing in the present paper, and

also figuring some of the more remarkable forms. I hope to add

additional interest to my work, by compiling a series of observations

on the habits of some of the species, from notes made on the spot by

Mr. H. W. Bates, who has in so many ways added greatly to our

knowledge of the entomology of Brazil.

I think it will be readily admitted that no family in the wide

range of the Insect world contains species which present such a

wonderful diversity of forms as are to be found amongst the Formi-

cidce ; so great is it, indeed, that nothing short of actual observation

could possibly lead the entomologist to suppose, in many instances,

that any relationship existed between the different members of the

same community. In my correspondence with both Messrs. Wallace

and Bates, I have always impressed upon them the importance of

collecting these insects from their nests, or under such circumstances

as would warrant their being considered sexes of the same species ;

to my request both these gentlemen have most willingly responded.

A few species obtained under such conditions, are of more real ento-

vol. i. f

mological value than hundreds of specimens taken at random, with-

out even a local habitation or a name.

Great as is our astonishment when we behold the endless diver-

sity, I may add, the eccentricity of form in these remarkable insects,

it will not for a moment bear comparison with the wonder which

irresistibly seizes us when we are led into the details of their

marvellous individual economies. Wonderful, doubtless, arc many

monuments of engineering skill — vast tunnels excavated under lofty

hills, or hewn through solid rocks — mighty pyramids heaped up

thousands of years ago ; but the Ant ((Ecodoma), ages preceding

the epoch of the construction of our tunnels, or of the marvels of

Egypt, bored her highways beneath the rivers of Brazil, and raised

her mounds, which, when compared with the tiny architects, out-

strip even the gigantic pyramids themselves.

The three genera treated upon in the present paper are each

remarkable for readily distinguished characteristics : Cryptoeerus

especially for the endless diversity of form in the different species,

and many of the species for the extraordinary differences in the

sexes of the same community.

The species of the genus Pseudomyrma are distinguished by their

elongate form, petiolated abdomen, and by the greatly enlarged eyes of

all the sexes, in many species occupying the entire sides of the head.

In the genus Eciton we have the reverse of the genus Pseudo-

myrma ; at least it is so in the only sex yet discovered — the worker ;

in these the eyes are so small, that, except in two or three species,

they cannot be seen without a high magnifying power, whilst in

three species I have been unable to discover any eyes at all. I shall

now proceed to give some account of the habits of the genera, in the

order in which I have here enumerated them.

The habits of a few species of the genus Pseudomyrma have been

observed : most of these excavate the pith from dried twigs ; in the

tunnels or burrows thus formed the eggs are laid, and the young

brood developed : the communities are small, frequently not more

than twenty, exclusive of larvae and pupae. One species, P. termi-

taria, constructs its nest, or more correctly, takes \ip its abode, in the

tumuli of different species of Termcs : others form small elliptical

chambers in the outer walls of Termitaria, a single colony only

apparently occupying each chamber ; these are usually wide apart,

and do not appear to contain communities which have any connexion

with each other. The pupae of this genus of Ants do not spin

cocoons. The insocts, when at large, are to be seen coursing rapidly

over trees and herbage j their sting is very slight.

of Exotic Hymen optera. 07

The species of the genus Eciton are very abundant, and cannot

fail to attract general attention ; we are now acquainted with about

twenty species. The processions of these insects are of common

occurrence ; and the different colours of the species are very obser-

vable when the lines are seen upon the march, some, as Mr. Bates

remarks, appearing like " a liquid stream of metal." These Ants

are regular clearers of all animal matter, living or dead : when on

a foraging expedition, they spread out their columns, climbing over

every leaf, plant, shrub, and tree, putting the whole animal as well

as insect world into commotion and alarm ; shoidd any decaying

mass of vegetable matter fall in their way, it is instantly covered

with a living crowd, every chink and cranny is carefully searched,

after which the army resumes its march. All apterous insects, par-

ticularly BJattai and Spiders (the former being exceedingly nume-

rous under fallen leaves, especially in their larva state), are preyed

upon ; the larvae of Lepidoptera and Diptera fall an easy prey, as

well as the species of Formicidce. At other times a community of

Ecitons engage in a regular attack upon a nest of some peaceful and

industrious species of Formica ; the Ecitons crowd into the nest of

the ants, each seizing upon a helpless victim, and carry or drag it

out of the nest ; if the ant prove too bulky for a single Eciton to

carry, it is ruthlessly torn into pieces, two or more assisting in the

operation. The march is then commenced back to the nest of the

Ecitons, the living ants and the mangled remains of others being

probably conveyed there for the purpose of feeding the young brood

of the marauders.

Every community of Eciton oonsists of two distinct forms of

workers, besides the males and females. In the typical species, E. 7ia-

mata, the large worker, or soldier, is furnished with long, curved,

sickle-shaped mandibles ; there is no gradation either in the form

of these organs, or between these larger ants and the ordinary

smaller workers : these soldiers bear the proportion of about five to

one hundred of the smaller individuals. In other species, such as

E. vastator and E. erratica, described in the present paper, the

soldier workers have the head greatly enlarged, with mandibles of the

ordinary size ; but even here there is no trace of gradation between

the two forms : it is true that the smaller form has individuals

cliffering in size ; so also, but in a less degree, do the big-headed

soldiers differ in size ; but between the two distinct forms there are

no gradations which would unite them.

Although the ants belonging to this genus are so numeroxis in

Brazil that they cannot fail to attract the notice of the naturalist,

f2

68 Mr. F. Smith on some neiu Genera and Species

yet hitherto no one has been fortunate enough to discover either the

male or female of a single species ; " their societies," says Mr. Bates,

" arc so numerous, and their sting so severe, that an attack upon one

of their colonies is not to be rashly undertaken."

The species of the genus Crijptocerus are not unfrequently to be

observed on low trees and bushes in dry open places, or running

on branches of newly felled trees ; they also visit flowers abundantly.

The species generally are wood-borers, usually perforating the dead

branches of trees. The males and females are winged, the latter only

temporarily so. The typical species, C. atratus, has been observed

to construct its nests in the dead suspended branches of woody

climbers ; outside is seen a number of neatly drilled holes, but inside

the whole solid wood is perforated with intercommunicating galleries.

Each community appears to consist of a single female and two

kinds of workers ; the latter, in some species, are quite unlike each

other, differing in the form of the head, and in the armature of

the thorax and nodes of the peduncle. The species appear to bo

omnivorous, and are frequently attracted by the excrement of birds.

These insects, like those belonging to the genus Myrmica, do not, in

the pupa state, enclose themselves in cocoons.

The new species of the genus Epomidiopteron, from Mexico, is ex-

ceedingly interesting ; the only one previously described was from

Brazil. I also describe a new species of the rare genus Trigonalys,

from Mexico ; Shuckard has described one from South Carolina ; two

are therefore known from North America, four have been discovered

in South America, one in Celebes, one in Australia, and one in Europe,

making in all nine species of this beautiful genus.

This ant constructs a papery nest, in texture and appearance like

thin coarse brown paper ; it is usually attached to the underside of a

leaf, and about 2 inches long by 1 inch broad ; the inner chambers

are intricate and irregular : when alarmed, the workers issue forth

in great commotion, making a curious rattling noise by vibrating

their abdomens over the papery nest, apparently for the purpose of

intimidating their enemies.

This ant I believe to be destitute of organs of vision. In the

place where the eyes are usually situated, I discovered, with a high

magnifying power, a minute pit. Mr. Bates observed that this

insect showed a great aversion to light, taking every means of hiding

from it.

very large, subquadrate, rather longer than broad, with a central im-

pressed line between the antennae running upwards nearly to the poste-

rior margin of the vertex ; the head is delicately shagreened, and has a

regular set of scattered punctures, in each of which is a pale, short, erect

hair ; the anterior margin of the head and the mandibles rufo-fuscous,

the latter with a single tooth in the middle of its interior margin, and

a number of erect pale hairs. Thorax finely shagreened and slightly

pubescent; the legs pubescent. Abdomen subglobose; the nodes of

the peduncle subquadrate ; the first with a short, stout, acute spine

beneath.

72 Mr. F. Smith on some new Genera and Species

Worker minor. Length 1-3 lines. Of the same colour and punctation

as the worker major; small specimens are usually paler ; all the indi-

viduals have the head much narrower and longer than in the larger

form, and it is also widest in front. The thorax at the sides in front

is obscurely fuscous; this character is rarely observable in the large

examples. The antennas in this species are rather longer than in

E. rastator.

Hub. Ega.

The habits of this species are very singular ; it does not, like many

other species, march in long columns, crossing open spaces, and climb-

ing up trees and bushes, but constructs covered ways built of minute

grains of earth, beneath the protection of which the lines of foragers

march, when engaged in plundering other ants' nests ; if a gallery

of this kind is broken into, the larger workers or soldiers rear their

heads and gesticulate in a threatening manner. On examining this

species under a powerful microscope, I could detect only an irregular

pit in the usual situation of the minute eyes of this genus.

Genus Strumigenys, n. g.

Head cordate ; mandibles porrect, tridentate ; eyes round, placed ante-

riorly at the sides of the head, at the extremity of a broad, deep excava-

tion ; the antennas inserted in the excavation, into which they are

received in repose ; the flagellum 5-jointed; the scape three-fourths of

the length of the flagellum ; the ocelli placed in a triangle on the

vertex, obsolete in the workers. Thorax ovate, oblong, and attenuated

posteriorly in the workers ; the anterior tibia? only furnished with a

single spine at their apex. Abdomen with two nodes, the first attached

to the thorax by a short petiole ; both are subovate, the second twice the

width of the first ; the abdomen subovate, and pointed at the apex.

The genus Strumigenys is doubtless closely allied to the Daceton of

Perty ; these genera, with that of Oreetoynathus, form a small group

of ants, which appear to me to lead into the family of the Crypto-

ceridce ; they agree with the latter insects in having the antennas

placed at the sides of the head in a groove, into which they fall

when in repose ; they are also, like some species of Cryjotoceridce,

more or less ornamented with scales.

1. Strumiyenys mandibularis. (Plate IV. fig. 6$, 7?.)

S. rufo-ferruginea ; capite cordato ; abdomine laevissimo, nigro.

Female. Length 2$ lines. Kufo-ferruginous ; the head black and

opake, with the anterior and posterior parts ferruginous ; the mandibles

produced, with their apex curved inwards, forming an acute, stout tooth ;

there are also two short, stout, blunt ones near their apex on the inner

margin ; the antennae with the flagellum clavate, aud pointed a,t their

apex ; the head and antennae sprinkled with minute glittering- semi-

transparent pale scales. Thorax short, subovate ; the scutellum semi-

circular and prominent ; the metathorax abruptly oblique, deeply exca-

vated behind ; the legs with glittering scales. Abdomen subglobose,

the apex pointed ; the nodes subglobose, the first petiolated ; the second

segment obscure red ; the abdomen delicately aciculated longitudinally.

Worker. Length l£ line. The head, thorax, legs, and nodes of the

abdomen rufo-ferruginous, and sprinkled with minute glittering scales ;

mandibles elongate, produced, with three long acute teeth ; the head

more elongate than in the female. Thorax elongate and narrowed

behind ; the thorax and legs sparingly sprinkled with glittering scales.

Abdomen smooth, shining black.

Hob. St. Paul (Brazil). In the Collection of the British Museum.

This curious species is found, Mr. Bates informs me, running

slowly and prowling about the bark of trees.

Subfamily Attid^:, Smith.

Genus Myrmicoceypta, n. g.

Head oblong, narrowed anteriorly ; eyes round and prominent ; antennae

inserted in the middle of the anterior part of the head, outside of two

elevated carinae ; the flagellum subclavate, increasing in thickness to the

middle of the apical joint, which is pointed at the apex, and twice the

length of the penultimate joint ; the scape about one-fourth shorter

than the flagellum. Thorax oblong, widest in the middle ; the anterior

margin transverse, with the angles slightly produced; the scutellum

deeply emarginate, forming a tooth on each side ; the metathorax has

also a tooth on each side ; the superior wings with one marginal and

one submarginal cell. Abdomen attached to the thorax by a petiole

composed of two nodes ; the first subglobose, the second cup-shaped,

and as wide as the base of the abdomen.

The affinities of this very singular and minute ant are somewhat

difficult to assign. After a careful examination of the characteristics

of those genera to which, on a slight inspection, it appeared to me

most nearly related, I am of opinion that its situation in the family

is next to, or in the immediate vicinity of, the genus (Ecodoma ; it

agrees with the species of that genus in many important characters,

namely, in the form of the mandibles, in the situation and character

of the antennae, very closely in the venation of the wings, and in

the intermediate and posterior tibia? being destitute of spines at their

apex. I have only seen one sex — the female ; the discovery of the

males and workers will probably furnish other important characters,

which may show the exact situation that the genus ought to occupy,

should I not have assigned it its true one.

This insect is described as the worker of C. quadrimaculatus on

the authority of Mr. H. W. Bates, who took them in their nest ; of

this species he remarks, " The difference between the female and

worker in form is very remarkable : I find a constancy in the spines,

&c, in all the workers, showing that the species are constant in their

characters: the female has a spotted abdomen." The female is

described by KLug in his Monograph on the genus; I have also

described and figured it in the second volume of the < Transactions

of the Entomological Society,' new series.

Some examples of this species are of a much darker colour than

that of the description ; they are usually considerably smaller, and

are, I consider, the small form of the worker of this species ; the

margins of the head, &c, are of the same glassy whiteness, and con-

Head oblong in the $ and £ ; eyes small and round, situated in a

groove at the sides of the head, into which the antennas are received

in repose ; the antennae subclavate ; the scape as long as the funiculus,

and grooved beneath for its reception; the funiculus twelve-jointed;

ocelli in a triangle on the vertex in the § , but wanting in the $ ;

mandibles incrassate, produced, with their inner edge serrated. The

thorax subovate in the $> , oblong and narrowed posteriorly in the $ ;

the superior wings with one margin.il cell, open at its apex ; one sub-

marginal cell ; the discoidal cells obsolete ; legs stout and of moderate

length ; the claws of the tarsi simple ; the metathorax with a tooth on

each side of the insertion of the abdomen. Abdomen ovate, pointed at

Note. — In my 'Catalogue of the JFbrmicidce,- I included this insect

amongst those which form the genus Meranoplus. The species was

received shortly before my work- went to press, but the winged female

has come to hand subsequently. The neuration of the wings is very

different from that of the genus Meranoplus; I have therefore removed

it from the genus in which I provisionally placed it. It is one of

the most singular insects in the whole family of the Formicidos.

VII. — On the Coleoptera of the Salvages. By T. Vernon Wollaston,

' M.A., F.L.S.

The peculiar position of the almost inaccessible rocks of the Salvages,

which lie in the direct course from Madeira to the Canaries, though

somewhat nearer to the latter than to the former, give them an espe-

cial interest in the eyes of geographical naturalists, — particularly

those, however, who have had 'an opportunity of studying the pro-

ductions of the two neighbouring groups. The qucestio vexata, as to

whether these several Atlantic islands are not, in reality, the mere

exponents or outposts of an immense continent now for the most

part submerged, may perhaps never be solved ; yet certainly one of

the best methods of helping towards a solution is carefully to

examine the fauna and flora of what seem to be its detached por-

tions, and then closely to compare them with each other, in order to

ascertain whether they possess sufficient in common (after every

reasonable allowance has been made for the accidental intermission

Mr. T. V. "Wollaston on the Coleoptera of the Salvages. 85

of specimens, from time to time, by chance agencies) to render their

quondam connexion, thus far at least, probable.

The small size of the Salvages, which consist of two uninhabited

rocks (the minute third one being absolutely inaccessible) separated

by a channel of about twelve miles, added to the great difficulty of

approaching their few and dangerous landing-places *, render every

fact concerning them, correctly arrived at, doubly valuable; and

therefore I do not deem it necessary to apologize for these few pre-

liminary remarks on an enumeration of the eleven species of Coleo-

ptera which have been hitherto detected upon them. Six of these

(apparently new to science, or at any rate treated by myself as such)

were described in the ' Insecta Maderensia ' in 1854, and were due

to the indefatigable researches of T. S. Leacock, Esq., of Funchal,

who effected a landing on both of the islands during the spring of

1851 ; whilst the remaining five (three only of which would seem

to be novelties) have been lately communicated by my friend the

Barao do Castello de Paiva, who obtained them from the master of a

Portuguese boat, which was freighted from Madeira for the purpose

of gathering orchil and barilla, with which most of these Atlantic

rocks more or less abound. In the following catalogue I do not

undertake to pronounce for certain on which of the two islands the

five recently added species were collected, though I believe them to

be from the Great Salvage. Those discovered by Mr. Leacock were,

he informs me, from the southern or smaller island, — known, never-

theless, as the ' Great Piton.'

* I should add that, whilst accompanying my friend John Gray, Esq., to the

Canaries, in his yacht the ' Miranda,' two years ago, one of our main objects was

to explore thoroughly these remote and almost unknown islands. Accordingly,

sailing from Madeira on the 6th of January, 1858, we arrived off the Great

Salvage on the following morning, and, after lowering the boat, pulled towards

the rocks. The sea, however, ran so high, and the surf was so tremendous, that

we found it impossible to approach nearer than a stone's throw from the shore

without the utmost danger; for the boat must have been literally dashed to

pieces had we attempted to land. We therefore returned to the yacht (not

without a " ducking"), and resumed our voyage to Teneriffe.

T. head dark-piceous, and rather deeply punctured. Prothorax a shade

paler, and more strictly piceous, and with the lateral edges more or less

slightly rufescent; a little less deeply punctured than the head, but

rather more rugose, especially about the hinder angles ; abruptly trun-

cated both before and behind, and much narrowed posteriorly, — the

extreme hinder angles, however, being acute and prominent. Elytra

subovate, much shortened behind, but nevertheless rather produced in

the middle (t. e. at their apical point of junction) ; somewhat acute at

their humeral angles, much depressed, and most minutely and delicately

alutaceous all over, — causing their surface to be a little less shining

than that of the head and prothorax; regularly crenate-striate, and

with the interstices rather distinctly punctulated ; testaceous, but orna-

mented with two black or dark-piceous patches (common to both

elytra) which cover the greater portion of the surface, — the first being

comparatively small and transverse, placed at the centre of the extreme

base, behind the scutellum, and reaching on each side to about (or a little

beyond) the fourth stria, its portion between the third and fourth stria

being more or less backwardly produced ; and the second being im-

mensely larger, postmedial, sometimes much suffused, and of a zigzag

form, being produced both before and behind along the suture, and

extending on either side to about the seventh stria. Antenna and

palpi piceo-ferruginous ; and with the terminal joint of the labial palpi

only very slightly enlarged and subclavate (instead of securiform, as in

the ordinary Tan). Legs testaceous.

The three specimens from which the above description is com-

piled have been lately communicated to me by the Barao do Castello

de Paiva, to whom I have great pleasure in dedicating the species.

From the close resemblance of their elytral patches and colouring to

those of the Canarian examples of the T. discouleus, Dej., I had at

first supposed them to be the exponents of a merely depauperated

and slightly altered form of that insect, from (perhaps) a long isola-

tion on the small and remote rocks of the Salvages ; but a more

careful inspection has proved that such an opinion (as is too often

the case in like instances) is only a superficial one, and that the two

species arc not only altogether distinct in their minor features, but

even in their structural ones. Indeed, were it not that the speci-

mens from the Salvages arc essentially Tari in everything else. I

Mr. T. V. Wollaston on the Coleoptera of the Salvages. 87

should have been almost inclined to regard them as generically

removed from their 9,MrtSi-(Canarian) allies, — the scarcely expanded

(and only slightly subdavate) terminal joint of their labial palpi (I

believe, in both sexes) affording a marked difference from the immense

and largely securiform corresponding one (at any rate in the males)

of the normal members of that group ; but as such is the case, I

prefer treating them (at any rate for the present) as only very ano-

malous Tari. As regards their more evidently specific details, they

recede from the T. diseoideus in their smaller size and darker head

and prothorax, the latter of Avhich is more distinctly roughened and

punctured, more straightly truncated before and behind, and is much

more narrowed posteriorly (with the extreme hinder angles them-

selves more prominent and acute) ; in their alutaceous and more

shining elytra, which are shorter posteriorly (though rather more

produced in the centre), with their shoulders more acute, and with

their darker portions a little different, the basal patch being more or

less backwardly -produced between the third and fourth stria, and

the postmedial one larger and more suffused (extending on either

side to the seventh stria, instead of only the sixth) ; in their darker

palpi and antennas; and in their rather more coarsely serrated claws.

structure which is very conspicuous under a high magnifying power,

but which is only just traceable on the prothorax] ; lightly and regu-

larly subcrenate-striate, the strire being fine and narrow ; with two

punctures, just within the third stria, down the disk of each, and with

the interstices rather flattened. Limbs rufo-piceous ; the antenna;

brighter at their base.

The present Pterostichus, two female specimens of which have

been communicated to me by the Barao do Castello de Paiva, is

closely allied to the P. canariensis of Brulle, which I have taken

abundantly in Lanzarote, Fuerteventura, and Grand Canary ; never-

theless it is rather smaller and less brilliant than that insect, — the

entire surface of its elytra (at least in the females, of which I can

alone speak) being densely and distinctly alutaceous (a sculpture

which is just traceable even on the prothorax also) ; its prothorax is

a little less expanded anteriorly, and with its dorsal charrnel more

abruptly terminated both before and behind ; and its elytral striae

are finer, narrower, and shallower, with the interstices much less

convex.

Genus Harpaxtjs.

Latreille, Gen. Crust, et Ins. i. 201 (1806).

3. Harpalus pelagicus, n. sp.

H. oblongus, latus, subnitidus, niger vel nigro-piceus ; prothorace trans-

verso, convexo, ad latera subaequaliter rotundato (basi haud constricto,

sed paulo angustiore), utrinque leviter foveolato, angulis posticis ob-

tusis; elytris leviter crenato-striatis (stria subsuturali abbreviate lon-

giuscula) ; antennis rufo-ferrugineis, pedibus rufo-piceis.

Long. corp. lin. 4}-5.

H. oblong, broad, shining (but not very brilliantly so), and black (or,

when immature, piceous-black). Head rather large. Prothorax broad,

transverse, and convex, almost equally rounded at the sides (i. e., with

the edges in a continuous curve, — not being suddenly attenuated, or

constricted, posteriorly, though a little narrower behind than before ) ;

almost unpunctured, though with a shallow and obscurely punctured

fovea on either side, at the base, behind. Elytra lightly striated, the

stria? being finely but distinctly crenulated ; with the abbreviated

second stria longer than in the Madeiran and Canarian Harpali of this

type, and completely joining the sutural one at a great distance behind

the scutellum ; more truncated at their base than in the other Harpali

of this type, the humeral angles being less porrected and more obtuse ;

a little acuminated at their apex, but not minutely divaricate as in the

H. vividus. Antenna rufo-ferruginous. Leas rufo-piceous.

The Harpalus here described is one of a small cluster of Atlantic

forms, — four or five of which I have taken in the various islands of

the Canarian archipelago, whilst another, the H. vividus (if, indeed,

that insect be not in reality separable into more than a single

species), is universal throughout the Madeiran group. After a very-

careful comparison of the H. pelagicus with all the Harpali as yet

detected both in the Madeiras and the Canaries, I am perfectly satis-

fied that it cannot be referred to any of them ; though it has a

greater affinity, perhaps, with those of the latter islands than with

those of the former. Apart from minor characteristics, it differs

from them all in being rather broader throughout, as well as in the

shape of its prothorax, which is wide, transverse and convex, and

entirely unconstricted posteriorly (though a little narrower behind

than before), — its edges being in a continuous curve, and with its

angles therefore more obtuse than is the case in the allied species.

Its elytra, also, have their shoulders less porrected or acute (the

thickened hue between the extreme apex of each humeral angle and

the scutellum being almost straight) ; and their stria) are much more

perceptibly (though minutely) crenulated, and with the abbreviated

second one longer than in any of the allied forms, and moreover

completely joining the sutural one at a very considerable distance

behind the scutellum. Three specimens of it have been lately com-

municated by the Barao do Castello de Paiva, to whose kindness I

am indebted for the other novelties described in this memoir.

A single example of the common European C. centrimaculatum

was lately communicated (along with the three preceding insects

and the Blaps gages) by the Barao do Castello de Paiva, as coming

from the Salvages. It is not a very important addition to the fauna,

— for, being somewhat abundant both at the Madeiras and Canaries,

the species may have been accidentally naturalized through the in-

strumentality of the boats, which proceed there almost every year

for the purpose of collecting orchil and shooting gulls.

A fine series of this noble Acalles was captured by Mr. Lcacock,

on the 'Great Piton,' during the spring of 1851. It is somewhat

allied to the Canarian A. argilhsus, Schonh. (of which I possess

several specimens, collected at Taganana and Orotava, in the north

of Tcncriffc), — though much larger than, and perfectly distinct spe-

cifically from, that insect.

6. Deucalion oceanicus, Woll.

Deucalion oceanicus, Woll., Ins. Mad. 433 (1854).

The D. oceanicus is also due to the researches of Mr. Leacock, who

secured a fine series of it (now in the Collection of the British

Museum) on the ' Great Piton,' in 1851. It is a most interesting

insect, as representing a group of which three* remarkably distinct

exponents have been hitherto brought to light, — viz., one in the

Madeiras, the Salvages, and the Canaries, respectively. The genus

was established in the ' Insccta Madercnsia,' in 1854, to receive a

very rare and anomalous Longicorn detected by myself on the extreme

summit of the Dezcrta Grande during January of 1859, and subse-

quently by the Rev. R. T. Lowe and myself on the top of the almost

inaccessible Southern Dezerta, or ' Bugio '; so that Mr. Leacock 's

capture on the Salvages, of a kindred species, became at once a very

significant and suggestive one. It is, however, rendered still more

* I ought perhaps to say four, instead of tliree, — for a single (very old and

imperfect) example of an additional species, closely allied to the Dezertan one,

is in the collection of F. P. Pascoe, Esq. ; but from what country il came, lie is

unable to state. If therefore it should turn out eventually to be likewise a

native of one or the other of these Atlantic islands (which I cannot but regard

as probable), we should have another confirmation of the geographical exclusive-

ncss of this curious Eueeratic group. Another insect, from Lord Howe's Island,

in the South Pacific, has been described and figured by Mr. White, in the ' Pro-

ceed inga of the Zoological Society,' under the name of Deucalion Wollastoni,

but this belongs to a different, although nearly allied genus.

Mr. T. V. Wollaston on the Coleoptera of the Salvages. 91

important now, through the discovery that the Lamia gibba of Brulle,

peculiar to the Canaries, is in reality a Deucalion ; of which I have

been able to satisfy myself, from the comparison of many specimens

which I took during the spring of last year in Fuerteventura and

Teneriffe, — from out of the decaying Euphorbias, on the stems of

which the larvae would appear exclusively to subsist. And it is

worth remarking that M. Brulle, whilst describing the L. gibba in

Webb and Berthelot's ' Histoire Naturelle des lies Canaries,' in

1839, implies his conviction that it would constitute eventually the

type of a new genus : " Espece fort remarquable, et qui formerait

peut-etre une division nouvelle dans le systeme propose recemment

Taken in tolerable abundance by Mr. Leacock on the ' Great

Piton,' in 1851 ; and I have also lately received specimens from the

Barao do Castello de Paiva, which I believe to have been captured

on the 'Great Salvage.' I have not yet compared it accurately

with the many Hegeters which I have found during the last two

years in the Canaries ; but it evidently approaches very closely to a

species which is common in most of the islands (particularly, how-

ever, the eastern ones) of that group. Whether it will prove to be

identical with it, or only nearly allied, I will not undertake to say

at present ; but I must decide for certain when my Canarian material

is sufficiently assorted for examination.

11. Ditglus falvus, Woll.

Ditghts faints, Woll., Ins. Mad. 523 (1854).

A single specimen of this beautiful Ditglas was discovered by Mr.

Leacock on the ' Great Piton ' in the spring of 1851. For the

reason given under the Hegeter latebricola, I must decline at present

to pronounce for certain whether or not it is identical with the

D. concolor of Brulle, which I have recently captured in Grand

Canary, Teneriife, and Palma ; but my belief is, that a careful com-

parison will prove it to be conspecinc with that insect.

Such arc the eleven species of Colcoptcra which have been hitherto

detected on these small and remote rocks ; and it is interesting to

remark, that they are each of them exponents of a separate genus,

Mr. J. S. Baly on six new species of Chrysomela. 93

and represent as many as nine families, whilst five of the species

(i. e. nearly half of the entire number) are Heteromerous. Although

it may appear absurd, at first sight, to speculate from such scanty

data, it nevertheless is not difficult to decide, even from this material

(which, after all, is considerable enough from islands thus minute),

to which of the Atlantic groups these intermediate " stepping-

stones " are the more akin ; for if we remove the Cercyon centri-

maculatum and Blaps gages, which are common to both, from the

above list, we shall perceive that, of the remaining nine, eight are

most intimately connected with Canarian forms, — whilst two of these

(the Hegeter latebricola and Ditylus fulvus) will, in all probability,

be found to be absolutely identical with them. The Pterostichus

haligena, moreover, is very nearly related to the P. canariensis,

Bridle (belonging to a section, Orthomus, which apparently does not

exist in Madeira) ; the Harpalus pelagicus is, emphatically, on the

Canarian type ; the Acalles Neptunus finds its natural ally in the

A. argillosus of Tenerifle ; the Deucalion oceanicus is more akin to

the D. gibbus of the Canaries than to the Madeiran D. Desertarum ;

and the Opatrum dilatatum is but slightly removed from a representa-

tive of the same genus which is found in Fuerteventura and Lan-

zarote, — the Helops Leacocianus alone having perhaps more affinity

with a species from the Madeiras (namely, the Porto-Santan H. in-

femus) than with any of those from the Canaries ; though even of

this I have by no means, as yet, completely satisfied myself. So

that I think we may fairly conclude from these facts, that the Sal-

vages, if indeed they are to be considered as belonging physically to

either of the neighbouring groups, are essentially Canarian.

VIII. — Descriptions of sir new species of Chrysomela from the East.

By J. S. Baly.

1. Chrysomela Templetoni.

C. breviter ovata, valde convexa, obscure nigro-senea, nitida ; elytris sub-

globosis, obscure rufis, utrisque striis decern punctorum impressorum

biseriatim dispositis instructis. — Long. 3^-4 lin.

Very convex, obscm-e nigro-ameous, nitidous ; elytra obscure rufous.

Head nearly impunctate ; antenna? black, slender, more than half the

length of the body, subincrassate towards their apex. Thorax twice

broader than long ; sides slightly dilated from their base to before the

middle, thence rotundate-angustate to the apex: above smooth and

shining, sparingly impressed here and there with fine but distinct

punctures ; sides thickened, bounded within by a longitudinal depres-

sion. Scutellum semiovate. Elytra subglobose, smooth and shining,

94 Mr. J. 8. Baly on six new species

each impressed with ten rows of distinct punctures, the first abbrevi-

ated, the second running parallel to the suture, the others arranged in

pairs, the puncturing of the outer pair more distant than in the rest,

all the rows less distinct and nearly obsolete near the apex; outer

margin impressed with a single row of fine punctures; interspaces

smooth, indistinctly punctured. Body beneath finely punctured ; legs

slender, subelongate.

Ilab. Ceylon.

The form of the elytra and the slender legs give this insect a

different appearance from the rest of the genus.

2. Chrysomela Fortunei.

C. oblonga, valde convexa, nitidissima, iridescens ; subtus viridi seneoquc

variegata, capite pedibusque purpureis ; supra viridi-asnea ; capite tho-

raceque rufo-violaceo-maculatis, hoc transverso, a basi ad ante me-

dium ampliato, lateribus incrassatis, intra marginem profunde punc-

tatis, irregulariter bi-impressis, disco leevi, hie illic sparse punctato ;

elytris dorso obsolete gibbosis, infra humeros transversim impressis,

tenuiter punctato-striatis, pimctis in striis confuse biseriatim dispositis,

ad latera et apicem versus subdissipatis, interspatiis Iambus ; utrisque

plaga magna male definita baseos, vittisque postice rufo-violaceis, vitta

pone medium coerulea. — Long. 5$ lin.

Oblong, very convex, almost gibbous just behind the middle, nitidous,

iridescent; body beneath bright metallic-green, more or less inter-

mingled with aureous ; head and legs deep metallic-blue ; above bril-

liant metallic-green, variegated with rufo-violaceous. Head sparingly

impressed with minute punctures ; epistome semilunate, bordered above

by a regularly curved line; antenme slender, deep metallic-blue.

Thorax before its middle twice broader than long ; sides gradually di-

lated from their base to before the middle, thence suddenly rounded

and narrowed to the apex ; upper surface sparingly impressed here and

there with deep distinct punctures, sides thickened, boimded internal] y

by a number of large, deep, confluent variolose punctures, placed longi-

tudinally in the middle of which are two large, deeply impressed, ill-

defined irregular fovese ; the basal margin and an irregularly curved

marking on either side the disk, united with its fellow at the base, rufo-

violaceous. Scutellum smooth, semirotundate-ovate. Elytra broader

than the thorax, indistinctly dilated behind their middle, very convex,

more particularly on the hinder half, their middle portion almost gib-

bous ; siuface very smooth and shining, each elytron below the shoulder

with a well-defined transverse impression, which extends from imme-

diately within the outer border nearly to the suture ; finely punctate-

striate, the punctures on the stria; irregularly arranged in a double

row, the striae themselves, about nine in number, becoming confused

and irregular on the side and towards the apex of the elytron ; inter-

spaces on the disk smooth and nearly impunctate, those on the sides

of Chrysomela from the East. 95

and apex impressed with very fine remote punctures ; whole surface

distantly reticulate-aciculate ; a large irregular ill-defined patch at the

base, nearly covering- the space above the transverse groove, and four or

five broad vittae, confluent at their base and apex, extending from the

hinder margin of the groove to the apex of the elytron, rufo-violaceous ;

in the centre of the hinder disk is also a short deep-metallic-blue stripe.

Hab. Northern China. Collected by Mr. Fortune.

This beautiful species is very closely allied to C. quadri-impressa,

and when first received, I considered it as merely a local variety of

that insect ; subsequently, however, it has been sent in some abun-

dance, and after a careful examination of many individuals, I have

come to the conclusion that it has a just claim to be considered a

good and distinct species. It differs from C. quadri-impressa in the

following characters: — it is larger, less regularly oblong, being

slightly broader behind ; its convexity is greater, particularly on the

hinder portion of the elytra, which are also obsoletely gibbous in

their middle ; the whole body is much smoother, far less closely

and coarsely punctured ; the punctate striae on the elytra are di-

stinct over nearly the whole surface, whilst in the other species

they are so mixed up with the coarse irregular punctation of the

whole elytron, that they are only visible at the base ; the thorax is

more dilated on the sides, its disk is smoother and covered with much

finer punctures, interspersed here and there with a few deeper im-

pressions, which are much larger and more distinct than those in

0. quadri-impressa ; lastly, the grooved line bounding the upper edge

of the epistome, instead of being triangular, forms a regular curve.

3. Chrysomela Stalii.

C. ovata, convexa, nitido-cuprea ; thorace disco lasvi, impunctato, lateribus

a basi ad paullo ante medium leniter ampliatis, hinc ad apicem rotun-

dato-angustatis, incrassatis, intra marginem profunde punctatis ; elytris

profunde punctato-striatis, punctis magnis, striis per paria subapproxi-

matis, hie illic sulcatis. — Long. 4 lin.

Ovate, convex, shining cupreous. Head finely but sparingly punc-

tured. Thorax nearly twice broader than long ; sides moderately di-

lated from the base to just before their middle, thence rotundate-an-

gustate to the apex : upper surface smooth and shining, convex and

inipunctate on the disk; sides incrassate, bounded within, for their

whole length, by a broad but shallow longitudinal groove, the surface

of which is covered with large, deep, round punctures ; these, although

somewhat crowded, are rarely confluent. Scutellum smooth, impressed

in the middle with a single fovea. Elytra broadly ovate, very convex,

deeply punctured, the punctures varying greatly in size and depth, and

arranged, somewhat irregularly and at unequal distances, in ten longitu-

96 Mr. J. S. Baly on six new species

dinal rows on each elytron, — the first row abbreviated, the others ap-

proximating in pairs ; on the outer border is also a single row of finer

punctures ; interspaces shining, slightly swollen, impressed with a few

fine scattered punctures ; the striae here and there deeply sulcate.

Body beneath subremotely punctured.

Hab. Northern China.

4. Chrysomela separata.

C. oblonga, convexa, nitido-cuprea ; thorace transverso, lateribus rotun-

datis, subincrassatis, profunde rugoso-punctatis, disco spai-se hie illic

fortiter punctato; elytris profunde punctatis, punctis in striis inter-

ruptis dispositis. — Long. 4 lin.

Oblong, convex, shining cupreous. Head vaguely punctured; an-

tennas scarcely half the length of the body, robust, nigro-aeneous.

Thorax twice broader than long; sides slightly ampliate-rotundate,

narrowed in front : disk sparingly covered with large, deep, irregularly

crowded punotures; sides incrassate, deeply and coarsely rugose-punctate,

their inner edge bounded by a longitudinal depression. Scutellum

smooth, impunctate. Elytra subovate, convex, deeply porose-punctate ;

punctures large, somewhat irregularly arranged in interrupted longitu-

dinal rows (about ten in each elytron), which indistinctly approximate

in pairs; interspaces smooth, slightly swollen, impunctate. Body

beneath shining cupreous, finely but remotely punctured ; legs nigro-

seneous.

Hab. Northern India.

At once distinguished from the preceding species (to which it is

otherwise closely allied) by its narrower and less convex form, and

by the rugose lateral border of its thorax.

5. Chrysomela Boivringii.

C. oblonga, convexa, nigro-aenea, nitida ; thorace disco fortiter- et irregu-

lariter-, lateribus rugoso-punctato ; scutello elytrisque rufo-testaceis,

aeneo vix micantibus, his subcrebre subseriatim punctatis ; abdomine

ad apicem plus minusve rufo-testaceo. — Long. 4 lin.

Oblong, convex, nigro-aeneous, nitidous ; scutellum and elytra rufo-

testaceous, with a faint metallic reflexion. Head punctured ; antennas

half the length of the body, slightly incrassate towards their apex.

Thorax nearly twice broader than long; sides slightly rounded, narrowed

towards their apex, sometimes notched at the base, anterior angles sub-

acute : disk irregularly punctured ; sides moderately incrassate, coarsely

rugose, boimded within by a longitudinal depression. Elytra four

times the length of the thorax, oblong-ovate, sides slightly oval, apex

regularly rounded ; above moderately convex, surface covered with

numerous irregular rows of deeply impressed but not very large punc-

of Chrysomela from the East. 97

tures ; interspaces smooth, impunctate. Body beneath dark metallic-

green, the posterior border of the three or four apical segments, and in

some specimens the entire apex of the abdomen, rufo-testaceous.

Hah. Hong Kong. Collected by J. Bowring, Esq.

This pretty insect ought to stand near G.grossa and its congeners.

6. Chrysomela cingulata.

C. elongato-ovata, convexa, nigro-aenea, nitida, supra obscure cuprea ;

thorace lateribus incrassatis, intra marginem sulcatis et profunde punc-

tatis, disco tenuiter subcrebre punctato ; elytris fidvo-rufo marginatis,

punctato-striatis, striis bifariam dispositis ; antennarum articulo ultimo

penultimo fere duplo longiore, oblongo-ovato, apice angustato. — Long.

3-4 lin.

Elongate-ovate, convex, nigro-aeneous or obscure cupreous, nitidous ;

body above obsem'e cupreous. Head finely but distinctly punctured,

puncturing scattered on the forehead, rather more crowded on the lower

portion of the face ; antennae nigro-caeruleous, slender, rather shorter

than half the body, their apical joint oblong-ovate, its apex subacumi-

nate; three basal joints more or less fulvous beneath. Thorax twice

broader than long ; sides nearly straight and parallel behind the middle,

rotundate-angustate in front, more quickly narrowed at the apex ; upper

surface with its lateral borders thickened, and bounded internally with

a broad shallow longitudinal depression, more distinct at the base, its

surface covered with large, deeply impressed, irregularly confluent,

variolose punctures; disk, together with the thickened margin, sub-

remotely covered with distinct but fine punctures. Scutellum smooth,

shining, semi-ovate. Elytra slightly broader than the thorax, five times

its length ; sides subparallel, their outer margin bordered with fulvo-

rufous : each elytron with eleven rows of distinct, deeply impressed

punctures; the first abbreviated; the second running parallel to the

suture ; the eleventh finer, and placed on the extreme edge of the rufous

border ; the eight others forming four double rows of punctures, which

are placed at nearly equal distances on the disk ; interspaces vaguely

and distantly reticulate-strigose, minutely and subremotely punctured.

Beneath shining, distantly punctured ; legs covered with subremote

deep punctures.

Hub. Northern India.

Nearly allied to Chrysomela marginata, but easily separated from

that species by its larger size, finer punctation, and, above all, by the

different form and greater length of the terminal joint of its antennae,

which themselves are also more slender than in C. marginata. In

the present insect the last joint is more slender and nearly twice the

length of the penultimate, whilst in the other species it is broader,

shorter in relation to the penultimate, more regularly ovate, with its

upper edge towards the apex oblique.

Moderately convex, dark brown, more or less clouded with a lighter

shade, or even inclining to grey; head with a line of four tubercles

between the eyes, the antennary orbit large, a semicircular impression

above the epistome ; mentum large, quadrate ; labium transverse, entire,

ciliated in front ; prothorax very transverse, wider than the elytra,

the sides strongly dilated and margined with a double series of equal

serriform tubercles, and deeply sinuated in front for the reception of the

bead, the disc with a row of five tubercles on each side the central

line, the anterior pair accompanied by two others placed on the edge of

the prothorax ; scutellum small, quadrate ; elytra seriato-punctate,

slightly gibbous at the base, so as to be above the line of the prothorax,

a row of small tubercles along the side, above this another of three

oblong tubercles, followed by a third row which is incomplete in the

middle, and lastly close to the suture is a line of smaller tubercles run-

ning, with a slight interruption posteriorly, to the apex, — the sides less

strongly dilated than in the prothorax, but edged with a double row of

serriform tubercles of the same size (in some specimens there is a lighter

shade posteriorly, forming a band-like mark) ; antennas, palpi, and eyes

ferruginous, with a paler pubescence ; body beneath dark brown,

covered with small tubercles. Length 3 lines.

Closely allied to the former, but is smaller, less convex, the elytra

narrower, and their base being depressed, they are on the same line

with the prothorax ; the disposition of the tubercles is almost precisely

the same, except perhaps that they may be a trifle less marked ; the

colour in both species is somewhat variable. Length 2i lines.

The few characters which Erichson has given of Rechodes accord

perfectly well with the insects described above, except that the last

joint of the maxillary palpi is scarcely securiform, although very

broad and truncate. Rechodes is closely allied to Ulonotus and En-

dophlceus. To the former of these genera, M. Lacordaire refers, and

I think correctly, Bolitopluujus antareticus, "White ; and I would also

refer to it Asida serricollis, Hope. The genus Pristoderus of the

latter author, founded on the Dermestes scaler, Fab., is probably

identical with Ulonotus.

Distaphyla [Colydiidae].

Head small, transverse, scarcely visible from above, slightly dilated below

the eyes, wdth a broad antennary groove beneath. Antennas short, stout,

11-jointed, the two basal incrassated, the third longer than the rest,

which are very transverse, the last two forming a short compressed

club. Eyes large, round. Mandibles bidentate at the apex. Palpi

robust, the terminal joint of the maxillary elongate, subcylindrie, of

the labial obovate ; maxillary lobes narrow, ciliated. Labium very

small, subcordate, fringed with long cilia. Mentum large, narrowed

in front, rounded and dilated at the sides. Prothorax nearly qua-

drate, very irregular anteriorly, the margin granulate and setose.

Elytra elongate, subcylindrical. Legs short ; coxae not contiguous ;

tibiae; gradually enlarging at the extremity, terminated by two small

spurs, and bordered externally with a row of stiff seta3 ; tarsi wTith the

three basal joints short, hairy below. Presternum rounded posteriorly,

the mesosternum depressed.

Judging from the position which Erichson has assigned to his

genus Phlceonemus, this must be a near ally, although it cannot be

by any means likened to Colobicus.

grooved between the eyes ; prothorax narrowing slightly behind, the

sides strongly granulated in a double row which is divided from the

granulations of the disc by a smooth line, anteriorly two large oblong

lobes overhanging the head, separated from each other by a narrow

groove, but posteriorly from the rest of the prothorax by a broad deep

hollow, which extends beneath them ; scutellum small, triangular ;

Hub. Brazil (Eio).

Beddish-pitchy, rather sparingly clothed with short, scale-like, grey-

ish-yellow or almost golden hairs ; head and prothorax with a few grey-

ish setae, the latter with about five dark spots on its disc ; scutellum

rounded behind, closely covered with white hairs ; elytra uneven,

with several small granular tubercles, ranged in more or less inter-

rupted lines, each tubercle bearing at its apex a black erect rigid seta,

in the centre six dense fascicles of stiff black hairs, the first and third

of these nearer the suture than the second, an oblique stripe (composed

of more closely set hairs) below each shoulder, and towards the apex

another oblique patch of pure white hairs (composed, however, of two

distinct spots) ; legs dark ferruginous, with scattered grey hairs, the

femora varied with black, the tibiae with a black ring in the middle ;

antennae and palpi pitchy-ferruginous ; body beneath pitchy-brown with

pale greyish hairs. Length 3 lines.

This appears to differ from A. tuber culif era, Burm. (which, however,

I have not seen) in its larger size, the black fascicles, the yellow,

almost golden, tinge of its scale-like hairs, the absence of the shining

chestnut colour of the apices of the tibiae, knees, tarsi, &c. Bur-

meister in his description of this genus has overlooked the basal joint

of the antennae, and describes the second (last) joint of the club as

composed really of two, soldered together, and in this he is followed

by M. Lacordaire. I can find no trace of any such union, which, if

it existed, would give twelve joints to the antennae, and not eleven,

Differs from the last in its much smaller size, comparatively narrower

and longer elytra, in the more numerous tubercles, and brown fascicles

of hairs, the almost unvarying hue of the pubescence, although near

the shoulder and apex may be traced rather more densely set patches

of hairs than elsewhere, and the more uniform colour of the legs.

Black, very slightly shining, and nearly free from pubescence, except

two small patches on the anterior margin of the prothorax, and a short

oblique white stripe, which, however, may be resolved into three spots,

below the shoulder ; scutellum rounded behind, naked ; prothorax

covered with small flat granulations ; elytra with a large fascicle of

black hairs on the lower third of each, the tubercles varying in size, but

all furnished with a rigid black seta ; antenna?, tibiae, and tarsi ferru-

ginous. Length 2 lines.

Lemmis [Colydiidae],

Head vertical, rounded in front, and prolonged at the sides into two

short peduncles bearing the eyes. Antennae short, eleven -join ted, the .

last two forming a short ovate club. Prothorax short, very transverse,

narrower behind, broader than the head anteriorly, the sides strongly

denticulate. Elytra nearly regular above, not broader, except at the

base, than the prothorax. Legs slender, first tarsal joint scarcely

longer than the second.

The other characters of this genus are the same as those of Acropis,

to which, indeed, it is nearly allied ; the form, however, of the pro-

thorax, added to the apparent absence of asperities, and the peculiar

scaly crust, which covers the whole of the upper surface, as if a layer

of opake varnish had been applied to it, obviously prevent its union

with that genus. The shortness of the first tarsal joint, being more

of a comparative character, is, perhaps, of less importance.

Lemmis ccelatus. (PI. VIII. fig. 3.)

L. oblongus, grisescens, setis hamatis brevissimis obsitus ; antennis capite

Hub. Brazil (Rio).

Oblong, brown ?, covered above as well as beneath with a scaly crust

of a pale yellowish or greenish grey, with very short hooked hairs,

particularly on the margins of the prothorax and elytra, curving for-

wards on the former, and backwards on the latter ; head (including the

peduncles) narrower than the prothorax, this with seven well-marked

but obtuse teeth on each side; scutellum punctiform; elytra a little

wider posteriorly, each with three very slightly raised gibbosities near

the suture, another at the shoulder, and externally towards the apex

two or three more, but which are considerably less prominent ; antennas

pitchy, shorter than half the length of the head ; legs pitchy ; eyes

dark brown. Length li line.

In one of the two specimens now before me, the hairs are scarcely

evident even on the margins, being, apparently, more enveloped by

the scaly layer described above. In Mr. Fry's collection.

Ethelema [Colydiidse].

Head vertical, rounded anteriorly, and prolonged at the side into a short

peduncle bearing the eye. Antennae as in Acropis, but more robust.

Labium short, transverse, fringed with long hairs. Maxillary palpi

robust, the terminal joint short, stout, obliquely truncate ; the labial

with the two basal joints small, the third large, broadly subovate,

slightly truncate. Mentum quadrate, very large. Prothorax as broad

as the head, transverse, regidar and convex above, nan-owed anteriorly,

the sides margined. Elytra oblong, nearly parallel, the surface smooth

and regular. Legs rather slender ; tibias not ciliated externally, ter-

minated by two short spines. Prosternum produced behind.

The above include the characters which, combined with the total

absence of tubercles, chiefly separate this genus from Acropis.

the upper surface ; head small, partially retracted in repose ; prothorax

with two waved grooves on each side, the outer smallest, and fringed

with stiff hairs ; scutellum scarcely visible ; elytra punctato-sulcate,

the costae between them closely covered with stiff hairs ; body beneath

coarsely punctured, with a setaceous hair in the centre of each ; palpi

Larger and stouter in proportion in all its parts than the Cey-

I am unable, at present, to give any oral details of this curious

genus, which Mr. Walker has only very briefly characterized, at the

same time associating it with the Hydrophilidae ; it is, however, an

undoubted Colydian, and evidently nearly allied to Emmaglceus of

M. Leon Fairmairc. The large primo-abdominal segment and distant

posterior coxae suggest also an affinity with Bothrideres and Derata-

phrus ; but its head, vestiture, and habit altogether, point to a distinct

subfamily. It may be mentioned that all the coxae are widely

apart; the femora canaliculate beneath for the reception of the tibiae,

which are fringed with stiff hairs externally, and the anterior ter-

minated by two spines, the inner of which is much longer and curved,

whilst the outer, under a strong lens, is seen to be tridentate ; the

mouth is almost entirely closed below by the prolonged mentum ? (as

sides.

Anarmostes [Colydiidae].

Head subquadrate. Antennae short, eleven-] ointed, the two basal incras-

sated, the third longest, the rest gradually decreasing in length to the

eighth, the last three forming an ovate, compressed, perfoliate club.

Eyes large, round, slightly divided in front. Maxillary palpi sub-

cylindric, the last joint obliquely truncate, the labial smaller, subacurni-

nate. Prothorax elongate, narrower posteriorly, deeply sulcate, not con-

tiguous to the elytra. Scutellum punctiform. Elytra elongate, nearly

parallel, ribbed, wider than the prothorax. Legs short ; coxae not con-

tiguous ; tibiae spurred, somewhat dilated and more or less toothed

externally near the apex ; tarsi slender, hairy beneath, the basal joint

subelongate. Prostemuin prominent, keeled in the middle. Abdominal

segments gradually diminishing in size.

Allied to Sosylus, with which it also agrees in habit, but at once

distinguished by its triarticulate club and sulcate prothorax. I have

not dissected the mouth of my specimen (which I owe to the kindness

of Mr. Fry, by whom alone, I believe, it has been taken) ; but the

mentum seems to be very small, and attached internally to the large

subquadrate jugular plate, which M. Lacordaire has, apparently,

denominated the "sous-menton" ; the point of insertion of the palpi

is, however, not covered by it, but is more than usually obvious.

of the prothorax, each with five strongly marked costae, the intervals

with a double row of elongated punctures, giving the spaces between

to the ninth more or less transverse, the tenth forming a round com-

pressed club. Labrum small, entire. Palpi rather short, filifomi, the

last joint subcylindric. Mentum very transverse. Prothorax elon-

gate, with nearly parallel, slightly margined sides, constricted a little

at the base, produced anteriorly into a broad lobe overhanging the

head. Elytra lengthened, parallel, very convex. Legs short ; posterior

coxae distant; femora strongly grooved beneath for the reception of

the tibiae ; tibiae enlarged at their extremity, without spurs, ciliated

on their external margin; tarsi slender, the three basal joints very

short. Prosternum produced. The first two abdominal segments larger

than the others.

Although the second abdominal segment is fully as large as the

first, yet, as they exceed the remainder, this genus cannot be placed

in any group in which the segments are equal ; otherwise, as its

posterior coxas are not contiguous, it might be associated with

Pycnomerus, Apeistus, &c. In its scaly pubescence it differs from

Bothrideres, Sosylus, and all the genera of that group (and the cha-

racter, as well as the absence of vestiture, like the sculpture, appear

to me to be of importance in this family). The antennae, described

as ten-jointed, may probably have eleven, the club being composed

of two, soldered together. In the figure eleven joints are given,

but the third should be united with the second.

A. elongata, cylindrica, fusca, supra albido-squamulosa ; elytris seriatim

punctatis, interstitiis squamulosis.

Hah. Natal.

Elongate, cylindrical, dull brown, furnished above with stiff whitish

scale-like setae ; head coarsely punctured, with few scales ; prothorax

strongly and thickly punctured, with numerous scales between them,

the anterior margin on each side obliquely grooved; scutellum very

small; elytra very coarsely seriato-punctate, the alternate interstices

with a more closely set row of scales than the intermediate ones ; an-

tennae not longer than the breadth of the head, reddish-brown ; legs

reddish-brown ; body beneath dark brown, coarsely punctured. Length

31 lines.

Penthelispa [Colydiidae].

Head small, slightly dilated below the eyes. Antennae short, stout,

eleven-jointed, the last two forming a short ovate club. Eyes round.

Mandibles bidentate at the apex. Maxillary palpi robust, the terminal

joint broadly ovate, the labial smaller. Maxillary lobes short, ciliated,

somewhat falcate, the inner narrower. Labium very transverse,

rounded anteriorly, and finely ciliated. Mentum subquadrate, its an-

terior angles rounded. Prothorax subquadrate, scarcely emarginate in

112 Mr. F. P. Pascoe on some new or little-hioivn

front, with a narrow margin at the side. Elytra elongate, subparallel.

Legs short; coxa? distant; tibia? smooth externally, dilated at the

extremity, and terminated by two or three spurs ; tarsi stout, the first

three joints subequal. Abdominal segments equal. Presternum con-

tinuous with the mesosternum.

I believe this genus will be found to include that portion of

Erichson's Pycnomerus which is characterized by its eleven- jointed

antennae. Dechomus, distinguished by having eight only, has been

recently separated by M. Jacquelin du Yal. The two European

species, P. terebrans and P. inexspectus, with ten joints, will, there-

fore, alone represent the true Pycnomeri. The species described

below has veiy slightly impressed antennary grooves, a character

which, among the Pycnomerinae, does not appear to be of generic

importance.

Penthelispa porosa.

P. elongata, subdepressa, rufo-picea ; prothorace fortiter punctato ; ely-

tris punctato-striatis.

Hab. Brazil (Bio).

Elongate, subdepressed, reddish -pitchy ; head slightly convex in

front, moderately punctured ; prothorax longer than broad, a little

narrowed posteriorly, covered with large and somewhat remote punc-

tures ; scutellum indistinct ; elytra coarsely striato-punctate, the striae

very narrow, with the punctures oblong; legs smooth, the internal

border of the tibiae towards the extremity, especially of the anterior,

slightly spinulose ; body beneath pitchy-brown, with large shallow

punctures. Length 2 lines.

Hyberis [Colydiidae].

Head short, transverse, immersed in the prothorax nearly to the eyes.

Antennae of moderate length, arising beneath the lateral border of the

head, moderately thick, ten-jointed, the joints ovate-elongate, setigerous,

the first rather incrassated, the third longest, the tenth forming a pyri-

form club. Eyes lateral, round, rather prominent. Mentum nearly

quadrate. Palpi claviform, terminal joint of the maxillary much larger

than the others, shortly ovate, truncate, of the labial oblong-ovate.

Prothorax transverse, bisinuated in front, rounded and strongly ser-

rated at the side, narrowed behind. Elytra much wider than the pro-

thorax, broadly ovate, convex. Legs moderate ; coxae distant ; femora

robust; tibiae fusiform; tarsi short, the basal joint longer than the two

following. Abdominal segments nearly equal.

As the only specimen I have seen of this insect belongs to the

British Museum, I am unable to give any account of its oral

organs; but there can be no doubt that it is nearly allied to

Apeisttis, and it wo\ild therefore be interesting to know if it be

furnished with paraglossoe, as in that genus. It is remarkable that

the basal joint, which in Apeistus is very indistinct, and was con-

sidered to be a mere knob (and the insect, therefore, trimerous) by

Erichson, should be also in Hyberis so indented, that when viewed

sideways it seems composed (at least in the intermediate tarsus) of

two distinct joints ; but the absence of any division beneath shows

that it is not really so.

Hyberis araneiformis. (PI. VII. fig. 1.)

H. fuscus, tuberculiferus, fulvo-setosus ; antennis capite prothoraceque

longioribus.

Hah. Borneo.

Broadly ovate, dark brown, opake, covered with small tubercles

and short stiff fulvous hairs ; head scarcely more than half the breadth

of the prothorax, a thin patch of yellowish hairs in front of each eye ;

prothorax slightly convex, much broader than long, with two tufts of

yellowish setose hairs on the disc, and six stout teeth on each side ;

scutellum very indistinct ; elytra broad, convex, rounded at the side,

the edges serrated, a small tuft of black hairs on each at the base, and

a larger one common to both elytra behind and on the highest part of

their convexity ; antenna? about one-third the length of the whole

insect, all the joints, except the last, furnished with three stiff seta?

arising in the middle of each, two anterior and one posterior; palpi

ferruginous ; legs rough, with short thick hairs, tarsi ferruginous ; eyes

black; body beneath somewhat pitchy, coarsely punctured. Length

2| lines.

Pharax [Colydiidae].

Head short, transverse, rather widely dilated below the eyes, and deeply

inserted in the prothorax. Antenna? short, eleven-jointed, the two

basal incrassated, and nearly concealed above, the third longest, the

rest gradually diminishing in length and becoming transverse, the last

two forming a compact ovate club. Eyes small, round. Mentum

rounded at the sides and in front. Terminal joint of the maxillary

palpi triangular. Prothorax transverse, largely dilated and rounded

at the sides, narrowed posteriorly, the disc very convex and irregular.

Elytra connate, much broader than the prothorax at the base, short

and irregular. Legs moderate ; all the coxa? distant ; femora robust ;

tibia? fusiform, bordered externally with scale-like hairs ; tarsi short,

the basal joint longer than the second or third. Abdominal segments

nearly equal.

This genus, in habit like Uhnotus, is allied to the last (Hyberis),

from which the eleven-jointed antenna? and Particulate club will at

once distinguish it. The description of the mentum and palpi must be

received with some hesitation, as they were examined in situ. The

two specimens now before me are among those almost inexhaustible

1 14 Mr. F. P. Pascoe on some new or little-known

captures of Mr. Fry at Rio, which perhaps, partly from their small

size, and partly from the extremely limited area which many of the

insects of that country affect, it is almost hopeless to expect can

ever be obtained except by the most indefatigable and experienced

collectors. The number of undescribed genera which are almost sure

to be found in every extra-European collection that may be formed by

an accomplished naturalist, should not be overlooked by those who

are inclined to question the necessity 'of the multiplication of new

names.

FharcuB hticolUs. (PL VIII. fig. 1.)

P. ovatus, fuscus, tuberculiferus, griseo-setosus ; antennis capitis latitu-

dine aequalibus.

Hub. Brazil (Rio).

Ovate, dark brown, covered with short, stiff, scale-like hairs ; head

slightly concave above ; prothorax somewhat bilobed anteriorly, its

disc with four depressed tubercles ; scutellum deeply set ; elytra short,

convex, with about ten tubercles on the disc, the posterior being the

largest, the margins irregularly set with short stiff scales ; antenna;,

palpi, and tarsi ferruginous, the former about equal in length to the

width of the head. Length \\ line.

Cuoeites [Colydiidas].

Head transverse, much narrower than the prothorax and deeply inserted

in it, its supra-antennary borders slightly produced. Eyes large, and

very rough, from the facets being prolonged into short spines. Antennae

short, slender, eleven -jointed, the first and second slightly incrassated,

the third longest, the remainder to the ninth gradually decreasing in

length, the tenth and eleventh forming an abrupt ovate club. Maxillary

lobes ciliated, the external subtriangular, the internal narrower. Palpi

short, claviform; the terminal joint of the maxillary ovate-cylindrical,

of the labial ovate-oblong. Mentum subquadrate. Labium trans-

verse, ciliated anteriorly. Prothorax very transverse, narrowed and

sinuated anteriorly, as broad as the elytra at the base. Elytra convex,

short, the sides gradually rounded to the apex. Legs small; coxa;,

especially the posterior, very remote; femora compressed; tibia;

slightly enlarged at their extremity, ciliated externally, and terminated

by two short spurs ; tarsi short, slender, with long hairs beneath, the

basal joint very distinct. Abdominal segments gradually decreasing

in size.

The widely separated posterior coxae narrow considerably the

number of Colydian genera with which Chorites may be compared ;

at the same time, although the first abdominal segment is in every

way larger than the others, there is not the decided difference we

see in Derataphrus, Sosylus, &c. ; and if we exclude these genera,

Genera and Species of Coleoptera. 115

we are reduced to Pycnomerus, Apeistus, <fec. To none of these,

however, is our insect closely related, the contiguity of the whole

base of the elytra to the prothorax completely isolating it from all

of them and their allies.

Chorites aspis. (PI. VII. fig. 3.)

C. niger, subnitidus, squainis griseis indutus ; antennis, palpis pedibusque

ferrugineis.

Hub. Borneo.

Broadly elliptical, black, rather glossy, covered with short erect pale

greyish scales, which are disposed in narrow rows on the elytra and

form a regular fringe round their margins and the sides of the protho-

rax ; antennae, palpi, and legs ferruginous, the tibiae with a black stripe

externally and edged with a row of greyish scales ; body beneath dull

black, thickly punctured, the throat only covered with yellow scales.

Length 2£ lines.

There is a second species ? in my collection, also from Borneo ;

but, except in its much smaller size (about 1| line long), and a few

black scales being interspersed among the others, there is little to

distinguish it.

Discoloma [Colydiidae].

Erichson, Natur. der Ins. Deutschl. hi. p. 292.

Discoloma Fn/i. (PI. VII. fig. 2.)

D. piceo-ferruginea vel testacea, pubescens ; elytris parce punctatis ; an-

tennis, palpis pedibusque dilutioribus.

Hub. Brazil (Bio).

Pitchy-ferruginous, in some specimens testaceous, sparingly pubes-

cent ; head rather closely punctured, inserted in a deep emargination

of the prothorax ; prothorax very transverse, nearly twice as broad as

long, very finely punctured, the margins gradually but strongly dilated,

with its anterior angle rounded; scutellum small; elytra rather

broader than long, and as wide as the prothorax at the base, the disc

with several rather large, remote punctures, with a broad and strongly-

marked margin at the sides ; antennae, palpi, and legs pale ferruginous ;

body beneath pitchy, with a few scattered hairs. Length 1^ line.

Although Erichson has characterized Discoloma in very few words,

I cannot doubt that the insect described above is correctly referred

to that genus, as indeed Mr. Fry had previously suggested to me ;

the only difficulty is, that Discoloma is said to have the basal joint

of its antennae simple, or not enlarged, which is not the case in

the present species. However, the habit of the typical form appears

to agree with this, and is so remarkable — resembling some of the

Nitidulidee (Amphotis for example) — whilst the structure so nearly

i 2

116 Mr. F. P. Pascoe on some new or little-hioivn

accords with Cerylon, in close proximity to which Erichson has

placed the genus, that this discrepancy need not, for the present

at least, necessitate the generic separation of the two insects. In

addition to Erichson's description, the following generic characters

(most of them the same as in Cerylon) may he noticed in D. Fr;/i : —

Eyes narrow, transverse, scarcely prominent ; external maxillary

lobe long and very slender, ciliated at the apex (inner lobe not

seen) ; maxillary palpi short, the first joint veiy small, the second

greatly enlarged, the third subcylindrical, the fourth minute, acicu-

late ; the labial palpi with the second joint enlarged, the third

shortly conical ; mandibles bidentate at their extremity ; mentum

small, quadrate ; labium rounded anteriorly ; tarsi very short, the

three basal joints oblique, and hairy beneath.

Glyptolopus [Colydiidae].

Erichson, Natur. der Ins. Deutschl. hi. p. 292.

Glyptolopus Msteroidcs. (PI. YIII. fig. 5.)

6, late ovatus, piceus ; prothorace elytrisque rugoso-costatis.

Hub. Brazil (Rio).

Broadly ovate, pitchy-black; head coarsely punctured, small, ver-

tical, scarcely visible above, narrowed below the eyes ; antennae twelve-

jointed, the first large, incrassated, and uncovered at its insertion, the

second short, not thicker than the third, the remainder becoming

gradually stouter to the tenth and eleventh, the last small, closely

enveloped in long silky hairs; prothorax semicircular, very convex,

vaulted above and emarginate anteriorly, the centre with a broad longi-

tudinal groove, and a stout interrupted costa on each side, the lateral

margin strongly produced, the intervals coarsely punctured ; scutellum

triangular ; elytra as broad as the prothorax at the base, but not con-

tinuous with it above, the sides rounded and gradually decreasing pos-

teriorly, with five strong rugose costae on each, the intervals coarsely

punctato-granulate ; all the coxae distant, tibiae fusiform, strongly

fluted, not spurred, tarsi short ; prostemum very strongly keeled, pro-

duced behind, and received in a notch of the mesosternum ; first abdo-

minal segment nearly as large as the rest together; body beneath

coarsely punctured. Length 2 lines.

The few characters which Erichson has given of this genus, its

very peculiar habit (resembling an Onthoplulus), combined with the

acicular palpi of the Ceryloninoe, and its habitat of Brazil, would

seem to leave no doubt that the insect described above is correctly

referred to Glyptolopus. The antennae, however, are certainly

twelve-jointed, while Glyptolopus is said to have only eleven. Has

the little terminal joint been overlooked ; and the ninth, which is

nearly as large as the eleventh, been regarded as one of the three

forming the club ?

Alth^esia [Mycetophagidae].

Head deeply inserted in the prothorax, triangular, slightly dilated below the

eyes. Antennae longer than the prothorax, eleven-jointed, the last three

forming an oblong perfoliate club. Eyes large, round, very prominent,

rugose. Maxillary palpi with the second and third joints thickest, the

terminal obconic, truncate ; the labial short, triangular, approximate.

Maxillary lobes narrow, nearly equal. Prothorax transverse, narrower

and slightly emarginate in front, rounded at the side, the base bisinu-

ated. Elytra slightly convex, margined, the base closely applied to

the prothorax, but enlarging behind the shoulder, then rounded to the

apex. Legs moderate; coxae distant; tibiae fringed externally, en-

larging towards the extremity, and terminated by four or five short

spines; tarsi slender, hairy beneath, four-jointed, the anterior with the

penultimate very indistinct (male only ?).

Eesembles Mycetophagus in outline, but with a triarticulate club,

and large round, very rugose and prominent eyes.

AWicesia pilosa. (PI. VI. fig. 4.)

A. piceo-brunnea, griseo-pubescens, pilosa ; corpore infra pedibusque

rufo-brunneis.

Hab. New Guinea (Dorey).

Pitchy-brown, covered with a close greyish pubescence combined

with numerous soft, slender hairs ; head scarcely half the breadth of the

prothorax, sparingly punctured ; prothorax with three grooves on each

side, the inner two connected by a deep transverse one at the base ;

elytra slightly convex, widest behind the shoulder, with a very narrow

margin ; scutellum very small, triangular ; body beneath and legs dark

reddish-brown ; abdomen, femora and tibise with a fulvous pubescence.

Length 3 lines.

Atmctocerus morio. (PI. VI. fig. 5.)

A. ater; elytris prothorace longioribus alis chalybeatis; profemoribus

coxisque testaceis.

Hab. Moluccas (Batchian).

Black ; head nearly round, thickly punctured, closely covered with

short erect black hairs ; antennas extending nearly to the end of the

prothorax ; eyes large, widely separated above ; mandibles not project-

ing; prothorax narrower than the head, quadrate, hairy, shining:

scutellum sub triangular, obtuse behind ; elytra closely punctured.

118 Mr. ¥. P. Pascoe on some new or little-known

pubescent, nearly as long as the head and prothorax together ; wings

deep steel-blue, shining; abdomen black, slightly tinged with blue,

with a very remote greyish pubescence ; legs black, anterior eoxse and

femora testaceous, the intermediate darker. Length 11 lines.

Dioptoma [Lampyridaej.

Head exposed. Eyes very large, horizontally constricted, the upper

portion smallest, the lower much larger, and completely contiguous.

Antennas short, claviform, subapproximate, deeply set on each side of

the narrow prolongation of the front, twelve-jointed, the first two in-

crassated, the remainder forming an elongated club. Mandibles very

slender, curved, not toothed. Palpi robust. Prothorax transverse,

semicircular, not dilated at the sides. Scutellum rather large, tri-

angular. Elytra as broad as the prothorax at the base, gradually rounded

at the sides, narrow and flattened posteriorly. Winged. Legs mode-

rate ; intermediate coxae not approximate ; tarsi slender, the fourth

joint not bilobed.

Although I do not hesitate to refer this most extraordinary insect

to the Lanipyridae, yet it must be confessed that it is a very aberrant

form, and suggests no affinity with any Malacoderm genus that I am

acquainted with. Its head (composed, at least externally, almost

entirely of eyes, which are constricted in the middle like an hour-

glass) is fully exposed; the narrow vertex descends behind the

upper portion of the eye, and fills in the space behind and between

the constriction, and is prolonged in front to terminate in the labrum,

although, from the presence of numerous coarse hairs, the existence

of this organ cannot be positively asserted. The antennas are very-

short, scarcely extending to the prothorax, and show no traces of

being serrated. I am indebted for the only specimen I have seen

to Dr. Ernest Adams, of University College, after whom I have

named it. The abdomen of the specimen having been cut away,

apparently to facilitate (?) the mounting, the number of its segments

cannot be ascertained : the abdomen itself, however, appears to havo

been very small ; the metastemum must have exceeded it in length

as well as in breadth.

Dioptoma Adamsii. (PI. V. fig. 2.)

D. fusca, parce pilosa; scutello elytrisque pallide grisescentibus, his

plaga elongata fusca humerali.

Hab. India (Dacca).

Dark brown, rather sparingly clothed with pale semi-erect hairs,

especially on the prothorax ; head coarsely punctured, mandibles red-

dish-brown, antennae and palpi pale yellowish ; prothorax thickly and

coarsely punctured ; scutellum and elytra very pale greyish, inclining

to yellow, the latter irregularly punctured with several slightly-raised

longitudinal lines and a dark-brown elongate patch at the shoulder ;

body beneath and legs pale greyish. Length &i lines.

Cotulades [Tenebrionidse].

Head subquadrate, exserted, but not constricted behind. Eyes small,

lateral, round. Antennae submoniliform, short, thick, very hairy, the

basal joint longest, the rest to the tenth subequal, very transverse,

the eleventh smaller, truncate. Labrurn small, rounded anteriorly and

ciliated. Mentum subquadrate, produced at the sides. Labium trans-

verse, rounded in front. Palpi short, clavate, terminal joint ovate.

Prothorax subquadrate, wider anteriorly. Elytra ovate, convex. Legs

short; all the tarsal joints, except the last, very short.

To this genus belongs the Tagenia leucospilct of Mr. Hope ; the

head, however, not contracted behind into a neck, and other cha-

racters show that it is very distinct from Tagenia [Stenosis']; at

the same time it is difficult to point out a nearer ally. In this and

the following genus the intermediate legs appear to be without

trochanters.

Cotulades fascicularis. (PI. VII. fig. 5.)

C. niger, rugoso-punctatus ; elytris obsolete albo-fasciculatis,

Hub. Australia (Melbourne).

Dull brownish-black ; head and prothorax covered with large, coarse,

nearly confluent punctures, and sparingly furnished with stiff, decum-

bent, scaly hairs; elytra coarsely striato-pimctate, each with three

indistinct ridges and with eight to ten short fascicles of brownish-

white hairs, indeterminately arranged, but sometimes nearly wanting

(from abrasion ?) ; claws pale ferruginous ; body beneath strongly

punctured. Length 3 lines.

Elasctjs [Tenebrionidse].

Head rather elongate, scarcely exserted. Eyes small, lateral, undivided.

Antennae short, hairy, eleven -jointed, the first longest, the rest trans-

verse and more or less equal, except that the last is smaller than the

preceding one. Palpi moderate, filiform, the terminal joint ovate, sub-

acuminate. Mentum transverse, the angles roimded. Labium small,,

transverse. Prothorax subquadrate, irregular, much broader than the

head, projecting in front, and lobed posteriorly, slightly dilated and

serrated at the sides. Scutellum very small, quadrate. Elytra nearly

parallel, broader than the prothorax. Legs short; femora and tibia?

compressed, the latter ciliated externally ; tarsi very short and slender,

the last joint nearly as long as the rest together.

This genus is not very far removed from the last ; and, judging

120 Mr. F. P. Pascoe on some new or liltle-hiown

both from the figure and the description, I think that it is also allied

to Erichson's Latometus*.

Elascus crassicomis. (PI. YII. fig. 7.)

E. subdepressus, fuscescenti-varius ; antennis medio abrupte inerassatis.

Hub. Australia (Melbourne).

Bather broadly depressed, covered with coarse, curly, dusky-brown

hairs varied with paler or greyish markings ; head and prothorax grey-

ish-brown, the latter with four tubercles on its disc and the projecting

anterior portion strongly bilobed ; elytra bordered with hooked hairs,

with three waved costae on each, terminating posteriorly in as many

tubercles, between which and the apex is another and larger one, a

small oblique stripe behind the shoulder aud a broad band near the

apex ; antennae greyish-brown, the terminal half darker, with the third

joint much thicker than the two preceding, the fourth and succeeding

joints gradually diminishing in thickness ; legs dark brown ; body be-

neath pitchy, with yellowish-brown scaly hairs. Length 3 lines.

I have only seen two specimens, both of which were taken by

Mr. Bakewell, at Melbourne, under the hark of trees composing a

stock-yard fence.

Elascus lunatus. (PI. VII. fig. 8.)

E. subangustatus, fuscus, nigro-varius ; elytris albo-fasciatis.

Hub. Australia (Melbourne).

Rather narrow, slightly depressed, covered with coarse scaly hairs,

which are yellowish -grey on the head, but considerably darker on the

prothorax and elytra, or nearly black, the latter having three whitish

bands (the two anterior crescent-shaped, but sometimes nearly coales-

cing, the posterior straight) ; prothorax with four tubercles on its disc,

the anterior projecting portion rather broadly bilobed, each lobe form-

ing (so to speak) an additional tubercle ; elytra coarsely seriato-punc-

tate, each with three costae, the inner nearly obsolete except at the

base ; antennae not abruptly thickened in the middle, yellowish varied

with dark brown, especially the three terminal joints; legs ferruginous,

more or less marked with dark brown ; body beneath covered with

greyish-yellow scaly hairs. Length 2^ lines.

The post-prothoracic lobe is less developed in this species than in

the former, or, in other words, it is broader and less abruptly de-

fined. The two specimens (also captured by Mr. Bakewell) now

before me differ considerably in depth of colour and amount of white

on the elyt.ra ; but in this, as in other instances, the pattern is the

same.

Genera and Species of Coleoptera. 121

Docalis [Tenebrionidae].

Head rounded, exserted, the antennary orbit nearly dividing the eye.

Antennae short, covered with numerous small flattish hairs, the first

three joints longest, the rest transverse, the tenth larger than the

eleventh. Mandibles stout, bifid at the apex. Palpi robust, terminal joint

of the maxillary short, stout, of the labial obconic, obtuse ; external

maxillary lobe short, triangular, fringed, the inner narrow, toothed.

Mentum arising within the jugular plate. Pro thorax subquadrate,

scarcely wider than the head. Elytra ovate-oblong, broader than the

prothorax. Legs short, the intermediate furnished with trochanters ;

coxae not contiguous ; tibiae not spurred; tarsi with all the joints ex-

cept the last very short and fringed with spiny hairs. Prosternal pro-

cess quadrate. Mesosternum depressed.

The Tagenia funerosa of the Eev. F. W. Hope is, I think, refer-

able to this genus ; and, trusting solely to recollection of his type,

now in the Taylor Institute at Oxford, it is very close to, if not

identical with, my D. degener ; but without certainty on this point,

it is better to assume that they are distinct. The genus seems to

be referable to the Scaurinse, and, so far as my knowledge of the

group extends at present, it might follow Ammojphorus. The struc-

ture of the mouth, in reference to what I have called the " jugular

plate," but which appears to be the " sow-menton " of M. Lacordaire,

is very similar, judging from that author's description, to that of

Nyctoporis, which genus immediately precedes Ammophorus. The

larger penultimate joint of the antennae is suggestive in a slight

degree of the club of many Colydian genera ; indeed, there are so

many points of resemblance between several of the Heteromera and

the Colydiidae, as to justify a doubt whether they may not be more

than mere analogies.

Docalis exoletus. (PI. VIII. fig. 9.)

D. oblongo-ovatus, fuscus ; prothorace transverso.

Hah. Australia (Melbourne) ; Tasmania.

Oblong-ovate, dark brown, everywhere covered, but not very closely,

with semi-erect, stiff black scales (hairs), intermixed, especially on

the head and prothorax, with rusty-white ; prothorax slightly broader

than long ; scutellum rounded behind j elytra coarsely seriato-punctate,

marked with several slightly elevated longitudinal lines, which are

severally crested with a row of whitish scales ; body beneath punctured,

each puncture enclosing a short rusty hair. Length 2 to 3 lines.

For my knowledge of this and the species of the two preceding

genera, I am indebted to Robert Bakewell, Esq., who informs me

that they, and many other insects as well, are found beneath the

122 Mr. F. P. Pascoe on some new or little-known

bark of logs which are piled one on another in the formation of

stockades. Few of the many collectors in Australia appear to be

aware of the novelties which a careful examination of such localities

would afford them.

Docalis degener.

I), oblongo-ovatus, prsecedenti angustior, niger; prothorace a?quali.

Hub. Tasmania.

Narrower and darker than the last, with the prothorax at least as

long as it is broad, the scales whiter and less numerous and the punc-

tures larger, and the longitudinal lines on the elytra more prominent.

Length 2 lines.

Sphargeris [Tenebrionidce].

Head small, transverse, abruptly contracted below the eyes. Antennas

eleven -jointed, very short, gradually increasing in thickness from the

third, which is longest, the second minute, the first incrassated. Eyes

lateral, very small, round. Labrum narrow, not covering the man-

dibles, which are bifid at the tip. Maxillary lobes narrow, the ter-

minal joint of their palpi subsecuriform. Mentum subcordate, nar-

rower behind. Labium bilobed and ciliated anteriorly; labial palpi

long, the terminal joint ovate, pointed. Prothorax short, transverse,

narrower anteriorly, rounded at the sides. Elytra shortly ovate, very

convex. Legs short, more or less covered with spinous hairs ; tibia?

triangular, strongly spurred, the anterior sinuated externally; tarsi

short, the basal joint longer than the second. Presternum compressed,

cariniform.

Closely allied to Mr. White's genus Cheer odes (Voyage of the

Erebus and Terror, Ins. p. 12. tab. 2. fig. 12), but differs essen-

tially in tho antenna?, Chcerodes having (inter alia) a triarticulate

club (see PI. V. fig. 10) ; in both, however, they are eleven -join ted.

Broadly ovate, very convex, smooth, shining, testaceous, closely and

finely punctured ; scutellum small, triangular ; antenna? about as long

as half the breadth of the head ; eyes and mandibles black ; body be-

neath darker, punctured, with short scattered hairs. Length 3 lines.

second minute, the third longest, the rest more or less moniliform and

becoming gradually thicker upwards. Eyes lateral, small, round.

Maxillary palpi strongly securiform, the labial very short and thick.

Prothorax narrower than the head, much contracted behind. Scu-

tellum none. Elytra connate, very convex, broadly elliptical. Legs

moderate ; anterior coxae globose, not contiguous ; tibia? unarmed,

haiiy at the base internally ; tarsi short, thick, hairy beneath, the basal

joint longer than the second, the penultimate bilobed. Prosternum

produced, rounded posteriorly, and remote from the niesosternum.

An examination of the mouth might throw some light on the

affinities of this very curious little insect ; but as the only specimen

I have seen belongs to the British Museum, and moreover is not in

very good condition, this cannot be done at present. In habit it

resembles the Anthicidae, but the globose anterior coxae separate it

from that family ; the bilobed tarsi, an unusual character amongst

the Tenebrionidae, suggest an analogy, or perhaps an affinity, with

Phymatodes and Phobelhis. It is one of the many important cap-

tures of Mr. Bates in the valley of the Amazons; and as that gen-

tleman is preparing a series of papers on some of the insects of his

extensive collections, it is to be hoped that this and many other

curious forms which he possesses will be at no distant date more

amply illustrated.

Chcetylhis antJiicoides. (PI. VI. fig. 8.)

C. niger, nitidus ; prothorace elytrisque tuberculatis, tuberculis setigeris ;

tarsis pallidioribus.

Hah. Brazil (Ega).

Black, shining; head coarsely punctured, with scattered, erect,

setulose hairs, a semicircular groove between the antennary orbits;

prothorax and elytra covered with large tubercular elevations, arranged

in rows on the latter, each of which bears a long, erect, setose hair ;

tarsi and base of the tibiae internally with pale silky hairs ; labial and

maxillary palpi at the base pale ferruginous ; antennae setigerous, as

long as the head and prothorax together. Length 2 lines.

Dipsaconia [Tenebrionidae].

Head small, rather narrow and elongate below the eyes, deeply inserted

in the prothorax. Eyes transverse, undivided. Antennae rather short,

submoniliform, slightly hairy, the basal joint incrassated, the second

very short, the third longest, the remainder gradually decreasing in

length, but becoming broader and transverse, to the ninth and tenth,

the eleventh subovate. Labrum rounded anteriorly. Maxillary palpi

rather long, claviform, the last joint large, ovate, truncate ; the labial

very small ; external maxillary lobe broad, strongly ciliated. Mentum

124 Mr. F. P. Pascoc on some neiv or little-known

quadrate. Labium very transverse. Prothorax narrower than the

elytra, transverse, sinuated anteiiorly, its surface regular. Elytra

rather long, slightly rounded at the sides. Legs moderate ; tibia) bi-

calcarate, ciliated externally ; tarsi slender.

Allied to Ulodes, Er., which differs in the following points. In

Ulodes the head is short, not being prolonged below the eyes ; the

joints of the antennae are subequal and transverse, surrounded by a

dense whorl of squamose hairs ; the surface of the prothorax is very

irregular ; the elytra are short, and the body generally is covered

with short crisp scales. To Ulodes I refer Bolitophagus Sa/phira,

Newm., and Endopldoms variicornis, Hope. My genus Byrsax {ante,

p. 42) is also a member of this group of Tenebrionida) (Bolitopha-

ginae) : it is true I cannot quite satisfy myself that it is hetero-

merous, but I have no doubt a minute basal joint exists ; and in

other respects it appears to be congeneric with Diaperis horrida, 01.

(Asida liorrida, Walk.). Trox comutus, Fab., is also referable to

Byrsax.

Dipsaconia Bakewellii. (PI. VII. fig. 6.)

I), elliptico-ovata, pilosa, fulvo-brunnea ; elytris nigro-variegatis.

Hub. Australia (Melbourne).

Elliptic-ovate, brownish-fulvous, covered with short decumbent

hairs, among which others longer, nearly erect and slightly curved, are

interspersed ; prothorax nearly as wide as the elytra at the base ; scu-

tellum rather indistinct, subtriangular ; elytra nearly parallel at the

sides, rounded at the apex, striato-punctate, each with three costae, and

varied with four or five dull-black band-like marks ; antennae brown ;

body beneath ferruginous-brown, very sparingly pubescent. Length 3|

lines.

In this and the following species, both of which we owe to Mr.

Bakewell's researches, may be noticed, in certain lights, a glowing

fiery-red tubercle at the bottom of each elytral puncture.

Dipsaconia pyritosa.

D. elongato-ovata, hirta, rufo-fusca; prothorace elytrisque nigro-varie-

gatis.

Hub. Australia (Melbourne).

Elongate-ovate, reddish-brown, closely covered with short, thick,

strongly hooked hairs ; prothorax narrower than the elytra at the base,

the disc with a large irregular blackish patch ; scutellum indistinct,

subquadrate ; elytra rather broader behind, striato-punctate, marked

with several irregular, dull brownish-black patches ; antennae brown ;

body beneath and legs ferruginous-brown, sparingly pubescent. Length

3J lines.

Tithassa [Tenebrionidae].

Head small, exserted, its anterior border incrassated. Antennae stout,

moderately long, the first and second joints scarcely thicker than the

third, which is longer, the remainder to the eighth short, the last three

forming an oblong, loose, compressed club. Eyes small, lateral, round.

Epistome and labrum narrow, not covering the mandibles, the latter

broadly emarginate. Mandibles bifid at the apex ; terminal joint of the

palpi ovate, subacuminate, the second joint of the labial larger than

the third ; maxillary lobes subequal, fringed. Mentum subquadrate.

Labium rounded. Prothorax transversely subquadrate, narrower than

the elytra, its margins dilated. Elytra large, convex, broadly ovate.

Legs small ; coxa3 not approximate, the anterior cylindrical, transverse ;

tibiae not spurred ; tarsi pubescent beneath, the penultimate joint di-

lated. Prosternum pointed behind ; mesosternum depressed ; post-

intercoxal process triangular.

The majority of the characters of this genus point, as it appears

to me, to the Diaperinae, but the differently-formed tarsi and the

disproportion between the prothorax and elytra forbid its union with

that group. At the same time, the antennae come nearer those of

Pentaphyllus " in plan " than any other heteromerous genus that I

am acquainted with. It seems to be a common Rio insect.

Tithassa corynomelas. (PL V. fig. 7.)

T. testaceo-lutea, nitida, punctata ; oculis, antennisque, ab articulo sexto,

nigris.

Hob. Brazil (Rio).

Dark glossy testaceous, or luteous-brown, irregularly punctured

above, with a few very fine and extremely scattered slender hairs ;

eyes and last five joints of the antennae, including a portion of the

sixth, which are also more hairy than the rest, black. Length 3 lines.

Chaeiotheca [Helopidae].

(Dej.) Catal. des Coleopt.

Head moderate, subquadrate. Eyes large, transverse, contiguous to the

prothorax. Antennae short, claviform, the first joint nearly concealed

above by the antennary orbits, the four or five terminal joints com-

pressed and, except the last, more or less transverse. Labrum rounded

anteriorly. Maxillary palpi with the last joint securiform, the labial

ovate, truncate ; maxillary lobes short, strongly ciliated. Mentum

subquadrate. Labium slightly expanded at the sides, entire and

ciliated in front. Prothorax transverse, nearly as broad as the elytra at

the base, rounded at the sides, scarcely emarginate anteriorly. Elytra

elongate, their greatest breadth behind the shoulders, slightly curved

126 Mr. F. P. Pascoe on some new or Ktth-known

at the sides. Legs rather slender ; tarsi hairy beneath, the basal joint

longer than the succeeding one. Prosternum pointed behind, with a

narrow impression in the middle ; mesostemum notched for the recep-

tion of the prosternum ; post-intercoxal process pointed anteriorly.

This unpublished genus of Dejean's was placed by him nearly at

the end of his Tenebrionites, an heterogeneous assemblage, including

as it does Mejandrya, Pytho, Pezodontus, Camaria, &c. With the

last of these genera, however, and with its allies, Chariotheca must be

placed.

Chariotheca coruscans. (PL VI. fig. 7.)

C. atra, nitida ; elytris cyaneis ; corpore infra, antennis pedibusque ferru-

gineis.

Hab. Moluccas (Batchian).

Deep black, smooth, shining ; head and prothorax lightly and irregu-

larly punctured ; scutellum triangular ; elytra rich indigo-blue, seriato-

punctate (about nine rows), with numerous smaller punctures irregu-

larly crowding the interstices ; antennas not longer than the breadth of

the head, reddish-ferruginous, the last five joints with a few short scat-

tered greyish hairs ; palpi and legs, particularly the tibia3 and tarsi,

reddish-ferruginous ; body beneath ferruginous, inclining to chestnut.

Length 4~ lines.

Chariotheca litigiosa.

C, atra, nitida ; elytris chalybeo-cyaneis ; antennis tarsisque ferrugineis ;

corpore infra, femoribus tibiisque atris.

Hab. New Guinea (Aru).

Deep black, smooth, shining ; head with crowded oblong punctures,

often three or four more or less confluent, and then forming short lon-

gitudinal folds in the spaces between them ; prothorax with small

scattered punctures ; scutellum rather small, triangular ; elytra dark

green, punctured as the last ; antennas, palpi, and tarsi reddish-ferrugi-

nous ; body beneath, femora and tibiae black. Length 4£ lines.

Rather narrower than the former, the scutellum smaller, the head

differently punctured, the colour less brilliant, &c.

Chariotheca cupripennis.

C. atra, nitida ; elytris cupreis ; corpore infra, autennis pedibusque piceis.

Hab. New Guinea (Dorey).

Deep black, shining ; head, especially between the eyes, with many

oblong punctures ; prothorax irregularly pimctured ; elytra seriato-

punctate, the interstices crowded with very minute punctures, copper-

red, the suture rich green ; antennas and palpi ferruginous-brown ;

body beneath and legs pitchy. Length 4 lines.

Omolipus [Helopidse].

Head transverse, vertical, sulcated in front. Antennae short, gradually

increasing in thickness, the two basal joints small, the third longest,

the fourth to the seventh obconical and decreasing in length, the last

four subnioniliform, compressed. Eyes transverse, partially divided in

front. Labrum rounded anteriorly and ciliated. Mandibles bidentate

at the apex. Maxillary palpi securiform ; the labial approximate at

the base, with the terminal joint triangular. Maxillary lobes small, the

inner strongly hooked. Labium transverse. Mentum subtriangular,

truncate at the base, carinated in the middle. Prothorax convex, rounded

in front and at the sides, closely applied to the elytra, its parapleural

distinct. Scutellum small, triangular. Elytra connate, ovate, convex.

No wings. Legs stout ; anterior coxae globular, not contiguous ; tibiae

straight, unarmed; tarsi short, all the joints except the last dilated.

Prosternum wedge-shaped, produced, with a deep central impression ;

mesosternum notched for the reception of the prosternum.

In characterizing (Edemutes (ante, p. 51), the semilunar, sulcated

anterior portion of the head was described as the epistome, and M.

Lacordaire appears to have done the same in his description of Splue-

rotus *. The real epistome, however, is inserted beneath the anterior

border, and in Sphcerotus curvipes is completely hidden by it ; but, on

the other hand, it is almost entirely exposed in another common

species, Sphcerotus gravidus. In Omoliptus (at least in the species

described below ; for the character scarcely seems to be of generic

value), the labrum, which is rather strongly developed, also appears

to be inserted directly beneath the anterior border of the head, and

the epistome is therefore not apparent. The nearest affinity of Omo-

lipus is probably Misolampus, from, which, among other characters,

the presence of a very distinct scutellum will at once distinguish it.

This genus is another exception to the absence of the hook on the

internal maxillary lobe, a character which at one time was supposed

to distinguish the Helopidse from the Tenebrionidse. Another excep-

tional character is the approximation of the base of the labial palpi,

which are inserted in front of the broadly transverse, membranous

lower lip.

dark brown ; legs covered with short silky hairs. Length 6 lines.

Dedicated to Ezra Downes, Esq., of Calcutta, who, during his

J Elytris convexis, angulis posticis comutis.

$ Elytris deplanatis, angulis posticis muticis.

Ovate, dark pitchy-brown, sparingly furnished above with pale yellow-

ish-green scales; rostrum longer than the head, gibbous below the

eyes, and separated from them by a semicircular depression, with a

broad longitudinal furrow in the middle ; prothorax shortly ovate,

closely granulated, and covered with coarse deep punctures ; scutellum

none ; elytra very short, perpendicularly bent down behind, roughly

punctato-granulated, slightly convex in the male, with the posterior

angle produced into a long flexible process, flat and depressed in the

female, and without any prolongation ; legs moderate, furnished with

stiff scattered hairs, the femora orange-red, except at the apex (in the

female darker) ; antenna? black, shorter than the body, slightly hairy :

body beneath pitchy, coarsely punctured. Length 3A lines (cf),

3 1ines($).

Blapsilon [Cerambycidae].

Head short, scarcely convex in front. Eyes small, lateral, deeply emargi-

nate. Antennas shorter than the body, sublinear, distant at the base,

the first joint thickened, shorter than the third, which is longest, the

fourth moderate, the remainder very short and subequal. Labruni small,

slightly emarginate. Mandibles robust. Palpi stout, the terminal joint

elongate-ovate, truncate. Mentum very short and transverse. Pro-

thorax broader than long, narrower in front. Scutellum elongate, pro-

duced anteriorly. Elytra ovate, broader than the prothorax at the base,

elevated in the middle, and produced at the shoulder into a short, hooked,

horizontal process. Legs moderate ; coxae distant ; tarsi short, very

slightly dilated. Prostemum received into a notch of the mesostemum.

The scutellum of this genus is remarkable. It is not only un-

usually narrow and somewhat hexagonal in form, but it is projected

forwards on the prothorax, which is probably notched for its recep-

tion, although this point cannot be ascertained without risk of in-

jury to the specimen. Blapsilon must be placed near Tmesisternus.

There are two specimens in the British Museum, collected during

the surveying expedition of H.M.S. Herald.

The unusually large prothorax of this insect and its narrow,

tapering elytra at once suggest some Dorcadion form, but its real

position appears to be with Pogonocluevus and its allies. The

specimen from which the description has been drawn up is in the

Eopean collection at Oxford.

Omosarotes [Lamiidae].

Head exserted, vertical, quadrate in front. Eyes very deeply divided, the

two portions connected only by a narrow line. Antennae distant,

robust, shorter than the body, pedunculate, and ciliated beneath, the

This genus, with Scopadus, appears to enter into a small group

of South American Longicorns, of which the Cerambyx sericeus of

Perty may be considered as the type. This is one of Mr. Bates's

rarest captures, he having never met with more than two specimens ;

one is now in my collection, the other in his own.

is margined with a little white anteriorly, across their posterior third ;

head narrower above the eyes, the peduncles bearing the antennae

rather distant, with a longitudinal groove between them ; lateral tooth

X. — On certain Coleopterous Insects from the Cape of Good Hope.

By T. Vebxon Wollaston, M.A., F.L.S.

Having lately received a small, but very important, batch of

Coleoptera from my friend Mr. Bewicke of Madeira, collected by

himself during a short visit to the Cape of Good Hope in May and

June last, I purpose describing a few of the smaller species which

more immediately interest me, — either from their own singularity,

or from their near relationship to certain forms with which I have

long been acquainted in the Atlantic Islands. I may mention perhaps

that Mr. Bewicke's material, although got together very hastily, at

the worst season of the year, and under peculiar disadvantages (he

having omitted to take with him any nets, or other entomological

apparatus, on his hurried departure from Funchal), contained about

270 species ; and since a large proportion of these belong to the

smaller families, there are probably few collections which have been

brought to this country from the Cape Colony that have afforded so

fair a display of the minute Coleoptera of that almost inexhaustible

region. In the present Paper I shall not attempt to characterize

more than a very few of them, as I hope to reserve certain of the

others for separate notices, according as leisure and opportunities

may permit.

Long, corp. lin. lj.

The present insect is peculiarly interesting, as being the second

species hitherto detected of one of the most anomalous genera within

the whole range of the Coleoptera. The genus was established by

Mr. Westwood, in 1851, to contain a small (and then unique) beetle,

discovered by myself in Madeira in 1848, and to which he gave the

name of Cossyphodes Wollastonii. Subsequently it was ascertained,

by Professor Heer of Zurich, during his residence in the island in

1851, that the insect was an attendant upon ants, he having taken

seven or eight examples of it within the nests of (EcophtJiora pvsilla

around Funchal, — under which circumstances it has been since fre-

quently captured by Mr. Bewicke, myself, Mr. E. Leacock and others :

and I may add that I have taken it in similar positions in Teneriffe

and Gomera, of the Canary Islands. Hence the detection, by Mr.

Bewicke, of a new and very distinct species during his late visit to

the Cape of Good Hope becomes exceedingly important, though more

particularly in a geographical point of view, — as making it at least

probable that Cossyphodes is an African, and not merely an Atlantic,

form. In my Madeiran Catalogue, published in 1857, 1 called atten-

tion to the fact, insisted on by Mr. Leacock, that the eyes of the

Cossyphodes Wollastonii are not in reality qiiite obsolete (as inferred

by Mr. Westwood, and subsequently endorsed by myself in the

' Insecta Maderensia ') ; but that they certainly exist, although in

a very rudimentary state, immersed within the small oblique line or

fovea with which either side of the head is furnished (on its upper

surface) posteriorly. And it is satisfactory, therefore, to see, that

this suggestion as to the peculiarity of the organs of sight is entirely

confirmed in the species from the Cape of Good Hope, — in which the

eyes are remarkably apparent, though to a certain extent buried

within this lateral foveolet, or slit. In their minor details, the two

species of Cossyphodes are very distinct, the unique C. Bewiclcii dif-

fering, not merely in its more apparent eyes and bituberculated

head, but likewise in its rather broader, more elliptic, depressed and

almost unkceled body, alutaceous surface, and posteriorly-acute elytra.

Its entire margin, also, especially behind, is more recurved ; its pro-

thorax is shorter, and nearly free from any appearance of longitu-

dinal costac (there being only the faintest possible indication of an

obsolete line on either side) ; and the elytra have only three (instead

from the Cape of Good Hope. 135

of four) longitudinal costae down each, — and those extremely fine

and delicate ones.

Its habits appear to be the same as those of the Madeiran and

Canarian C. Wollastonii, as I am informed by Mr. Bewicke that he

captured it "in an ants' nest on the Atlantic side of the promontory

of the Cape, about three or four hundred feet above the sea." It

would seem to be very scarce, for Mr. Bewicke states that he

"searched diligently, but without effect, for more;" — adding,

" From the locality in which I took it, miles from even a road,

amidst thick imderwood and rocks, I should consider it as certainly

a true native of the Cape."

The two insects* on which the present genus is founded are so

very close, in general aspect and structure, to the Madeiran and

Canarian Eur ops, that it was not until I had examined them mi-

nutely that I could conceive it possible that they should perhaps be

regarded as distinct ; whilst even now I am anything but satisfied

that they ought not leather to be treated as aberrant members of

* Whether the Rhyzophagus eapensis and rufulus of Dejean's Catalogue,

registered as natives of the Cape, be these two insects (which is not impossible,

from their great external resemblance to Rhyzophagi), I cannot tell ; as, however,

they are mere Catalogue-species, it fortunately is not of much importance to

ascertain.

13(3 Mr. T. V. Wollaston on certain Coleojrfcrous Insects

that Atlantic group. Their main difference consists in the structure

of their tarsi, the first and second joints of which (instead of being

simple) are very broad, and deeply bilobed, — except in the hinder

pair of the male sex, where only the basal one is thus developed.

Moreover, as regards these hinder male feet, there may also be a

difference in the actual number of the articulations (as compared

with those of Europs) ; but unfortunately the structure is so obscure,

even beneath the highest powers of the microscope, that I am unable

to decide whether there are one or two minute joints concealed

within the lobes of the basal one. If there should be but one, then

the posterior male tarsi will be only trimerous, and therefore dimi-

nished in the number of their joints ; but if two, they will be

tetramerous (like the remainder of the feet in both sexes), their

form only being altered, — i. e. the second articulation (which in the

other feet is as large and cordate as the first) will be reduced to an

excessively minute size, like the penultimate one in all the feet. At

any rate, whether the number of the hinder tarsal joints of the male

feet be the same or not, m Mimema and Europs [and I may add that

it is nearly equally difficult to pronounce for certain whether they

are trimerous or tetramerous even in the latter also], the form of the

tarsi is unquestionably different, — the two largely-developed bilobed

basal joints in all the feet of Mimema except the posterior ones of

the male sex, where (whatever be the exact number of the following

minute articulations) the basal one only is thus constituted, giving

it a character which it is impossible to mistake.

Moreover, this tarsal peculiarity is not altogether unaccompanied

with minor differences (from Europs) even in its oral organs ; for in

Mimema the antenna? have their third joint a little longer than the

fourth (thus making a slight approach to Rhyzophagxis), and the

two divisions of their club are more compact, or less separated from

each other ; also the outer maxillary lobe, although narrow like that

of Europs, is not so aciculated, but almost palpiform, — appearing as

though articulated at its base, and with its long apical portion sub-

clavate. The ligula also of Mimema, although elongate and linear

as in Europs, is sharp and angular at its apex (between the palpi),

instead of being obtusely rounded, and with broad elongate mem-

branous internally ciliated paraglossae stretching out on either side

from the anterior angles. The general aspect of both groups is that

of Rhyzophagus ; but, apart from the many other differences which

will be gathered from the diagnoses, I may add that, whilst in the

latter the numerical formula for the tarsal joints is 5-5-5 and 5-5-4

in the two sexes respectively, that for Mimema (and indeed for

from the Cape of Good Hope. 137

Europs also) is either 4-4-4 and 4*4-3, or 4-4-4 In both sexes, — as the

case may be. If properly distinct, however, so completely does our

present genus imitate its Atlantic representative, that I have thought

the above generic title would not be altogether an inappropriate one.

Mimema pallidum, n. sp.

31. lineare, opacum, parce pubescens, rufo-testaceum ; capite protho-

raceque alutaceis, remote leviter punctatis, hoc quadrato ad latera

testaceis, concoloribus • pygidio rufescente ; antennis piceo-ferrugineis.

Long. corp. lin. 1^-lf.

The larger size, broader outline, and pallid hue of the present

Mimema, in conjunction with its more opake surface, ampler elytra,

and consequently less exposed pygidium, will, apart from all other

differences, immediately distinguish it from the following one. Al-

though apparently not a ^^>7(0/-5ia-feeding insect like the Atlantic

Europs, it would nevertheless seem to have something in common

with the members of that genus, as regards its habits ; for whilst

Europs more particularly delights in the viscous, adhesive exudations

in the interior of the rotten Euphorbia-stems, Mr. Bewicke writes

me word that the two species of Mimema " dwell in the thick sticky

matter at the bottom of the flowers of the common sugar-bush (a

Protea)," — which " sugar-bush," I am further informed by the Rev.

R. T. Lowe, is probably a corruption of " Sugarbosch" (the Dutch

ZuyTcerbosch), and that the plant is the Protea mellifera, Thunb., of

which there is a figure given in the Bot. Mag. t. 346.

Having been accustomed to collect in Madeira, Mr. Bewicke at

once recognized the present insect as a probably new species of

Europs ; though he informs me that he felt a little doubtful as to its

generic identity through the fact of finding it in flowers, — a position

in which the two hitherto detected species of Europs have never

been observed. Perhaps, however, the dilated tarsi of Mimema may

well accord with this slight difference in its mode of life ; though its

close resemblance to Europs in most of its other details and outward

contour, would certainly lead us to anticipate a considerable similarity

also, — which " similarity " is, I conceive, sufficiently established in

the peculiarity of its food to which I have just drawn attention.

The narrow outline, smaller size, more shining surface and shorter

elytra of the M. tricolor, in conjunction with its totally different

colour — the head, pro thorax and abdomen being dark, with the

elytra (which, however, have their scutellary and apical regions

more or less darkened also) pale-testaceous, and the limbs piceo-

testaceous, — will readily separate it from the foregoing species. As

already stated, it was found by Mr: Bewicke in company with the

M. pallidum.

Two examples of this little Atomaria were captured by Mr.

I cannot say. It is very nearly akin to the common European

A. apicalis, but certainly distinct therefrom, — as will be readily

seen when the species are placed alongside each other beneath the

microscope. It is of a more pallid-castaneous hue, and of a rather

more ovate (or less elliptic) form; its punctation is deeper and

more distant, its surface less pubescent, its prothorax is less drawn-

in anteriorly (being a trifle more rounded at the sides and of almost

equal breadth before and behind), rather more truncated at its base, '

and more evidently margined (particularly at the lateral edges), its

elytra are not quite so ample at their extreme apex (where they do

not completely conceal the pygidium), and its limbs (especially the

antcnnal club) are altogether darker.

140 Mr. T. V. Wollaston on certain Coleopterous Insects

The diminutive insect from which the above characters have been

drawn has so much the resemblance of a minute Mycetcea, that it

was not until I had examined it attentively that I perceived its

distinctions. Its maxilla and under-lip I have unfortunately not

succeeded (in the single specimen which I broke up) in securing ;

but its antenna), upper-lip, mandibles, maxillary-palpi and feet, I

have mounted carefully in balsam, and have thoroughly inspected.

In all these details it offers slight differences from the corresponding

ones both of Mycetcea and Symbiotes, to which it is closely allied ;

but in the structure of its much more abbreviated antenna?, which

are 10-arriculatc and with a 2-jointed club, it recedes from them

altogether, — the antennas of both of those genera having eleven

joints, with a 3-articulated club.

The present Cis has. to me at least, a peculiar interest, from it

being of precisely the same type as the Madeiran C. Wollastonii, of

from the Cape of Good Hope. 141

Mellie, — a species remarkable for its obloug form, large subporrected

head, nearly tmproduced prothorax, almost naked surface, and sub-

raacidated elytra. As regards the last, however, the C. subornatus

has but a very obscure tendency to assume that singularity of mark-

ing which in highly-coloured examples from Madeira is often so

apparent ; nevertheless the same tendency is just traceable in all the

specimens which Mr. Bewicke collected, whilst in one of them it is

particularly conspicuous. In minor details, the Cape of Good Hope

species is much smaller, narrower, and a little more linear, than the

Madeiran one, its clypeus is more truncated in front, its pubescence

still shorter and more remote (being imperceptible except under a

powerful lens), its prothoracic punctation rather deeper and less

dense, and its scutellum a trifle more triangular. Whether the

C. subornatus and Wollastonii are at all abnormal in their structure,

or whether (as I rather suspect) the generic details given by Mellie

in his excellent monograph are not quite correctly drawn, I cannot

tell ; but certainly in both the above species the maxillary palpi are

much longer than he has figured them, and the inner lobe, although

very short, is more apparent (being internally membraneous and

most powerfully ciliated) ; the ligula, too, is considerably more

elongated (being rounded anteriorly, and gradually contracted before

the base) ; and the ultimate joint of the labial-palpi (instead of

being ovate, as he has represented it) is narrow, sublinear and

aciculate, — being of a very much less width than the preceding one.

I should mention perhaps that, judging from the description, the

C. subornatus is perfectly distinct from the three species — Guerinii,

Capensis, and muriceus — stated by Mellie to come from the Cape of

Good Hope.

So very closely does the present insect, at first sight, assimilate

Hylastes, that I had regarded it, previous to a critical examination,

as an abnormal member of that group, in which the external edge

of the tibiae were edentate. But, on closer inquiry, it proves to be

undoubtedly one of the Curculionidce, the entire structure of its

slender, toothless, apically uncinate tibiae, and its unreceived tarsi,

assigning it to that family. From Rhyncolus, however, to which it

is clearly related, it recedes completely in its excessively short, broad,

thick and subtriangular rostrum, in its very abbreviated and differ-

ently constructed antennse (which have apparently no lateral scrobs

for the reception of their scape), in its minute, punctiform scutellum,

its more globose, exposed head, and in its longer feet ; and I should

consider that the Madeiran Hexarthrum is perhaps its nearest de-

scribed ally, — though in that genus the funiculus is only 6-articulate,

whereas in Stenoscelis it is 7-. I have two uncharacterized insects

from the Canaries (which reside in the rotten pine-trees of the old

Finals of Grand Canary and Teneriffe) to which it is also much akin ;

but in them the funiculus is, likewise, hexamerous, the antenna) and

rostrum are, both of them, differently formed, and the scrobs is very

apparent.

The very extraordinary insect from which the above structural dia-

gnosis has been compiled is an undoubted member (as indeed I have

been, also, assured by both MM. Jekel and Waterhouse) of the sub-

family Brachyderkles, retaining the essential character of the various

groups around Polydrosus, though widely differing from them all in

its actual modifications ; and it would seem probable that the New

Zealand Rhadinosomus acuminatus may perhaps be found to be

amongst its nearest known allies. In its general contour and sur-

face it is not altogether unsuggestive (to me at least) of a very ex-

treme form of some of the longer-snouted, and more deeply sculp-

tured, SitoncB; nevertheless its real details of structure debar it

altogether from admission into that genus, it having scarcely a single

point in which it absolutely agrees with it. Indeed in its elongate

and very slender antennae (with their abruptly clubbed scape, almost

unthickened clava, and peculiar proportions of funiculus-joints — the

first, third, and fourth of which are subequal, whilst the second is

144 Mr. T. V. Wollaston on certain Coleopterous Insects

short, and the fifth, sixth, and seventh scarcely longer than the

second), its extremely long, convex and arcuate rostrum (at least for

the Brachyderides) — with its nearly apical and excessively oblique

scrobs, and its small, sunken and oblique eyes (which are placed

altogether beloiv the upper surface of the forehead) — in conjunction

with its narrow, fusiform body, deeply sculptured, costate surface,

apically cleft elytra, and comparatively un dilated third tarsal -joint,

it presents a combination of features essentially its own.

When viewed laterally, its small, oblique, subreniform, deeply

immersed eye, situated so much lower than the frontal (or rather

nasal) projection above it, added to the remarkable curvatiu'e of its

long and blunt rostrum — which is. bent downwards at the extreme

apex, comparatively straight along the middle, and suddenly humped

or rounded at the base, just before its junction with the forehead (a

structure, however, which is caused mainly by a transverse constric-

tion across the forehead itself) — have a most comical effect — pre-

senting a quaint analogy (in likeness) with the American Tapir

( Tapirus terrestris), from which I have consequently borrowed its

specific name.

The present genus is usually known in collections as Cheirodes ;

it has never, however, been characterized under that name, and

therefore the above title must necessarily supersede it. The A.

oculata is very closely related to the A. granidata, Casteln. (the

Cheirodes scarabceoides of Dejean's Catalogue), from Senegal, — of

which a specimen, for comparison, has been lent me by Mr. Water-

house: it is, however, darker (or less piceous) than that insect,

and not quite so shining ; its head and prothorax are much more

densely and finely punctured, and its elytra are a little more per-

ceptibly longitudinally striated. Its head, too, is a trifle more eraar-

ginated in front (the lobes being very rounded and obtuse, and not

minutely recurved at their respective apices as in the "West African

species) ; its prothorax is less rounded at the sides (being somewhat

146 Mr. F. Smith on some new Genera and Species

narrowed, or straightened posteriorly, and with the fore-angles, though

obtuse, less decidedly rounded off) ; and the two minute teeth behind

the two larger ones, of its front-tibioc, are in the A. oculata, nearly

obsolete. Its most decided difference, however, is in the shape of

the eye, — which is considerably larger and more circular, and extends

much nearer to the lateral edge (and hinder angle) of the clypeus,

than is the case with the A. granulata.

Although a representative (viz. the A. sardoa, Gene.) has been

described from Sardinia, it is probable that the group is essentially

an African one, and that many allied forms will consequently, in the

course of time, be brought to light. In addition to the present

species, from the Cape of Good Hope, and the A. granulata from

Senegal, I possess a third (nearly related, I imagine, to the Sar-

dinian one) from the Canaries, captured by myself near Arrecife,

on the sandy shores of the island of Lanzarote. Of the A. oculata

there was but a single example amongst the insects collected by

Mr. Bewicke ; but I have seen a second in the possession of Mr.

Waterhouse.

XI. — Descriptions of new Genera and Species of Evotic Hymenoptera.

By Frederick Smith, Esq., Assistant in the Zoological Department

of the British Museum.

Of all the various genera of bees, there is not one which contains

more brilliant and beautifully coloured species than Augochlora ; the

Mexican species, described in the present paper, are remarkable for

the extreme richness of their colouring ; this genus contains the

Halicti of the New World. They are separated, however, from the

genus Halictus by several structural characters, and also by the

different habit of the species ; all, whose economy I have ascer-

tained, burrow in putrescent wood, or construct tunnels under the

bark of trees. Eight new species of Bomhus are described, those

from Mexico are amongst the most beautiful of that widely distri-

buted genus.

Family Andremidae.

Of this species Mr. Bates remarks, — " A most lovely species of

bee, exhaling a very powerful aroma months after death. One day,

on breaking a piece of dead branch to pieces, I came upon a row of

cells containing these bees, already enclosed and ready to escape.

There were about a dozen cells placed end to end, of which two con-

tained pupoe ; most of them escaped : I could only secure four or

five."

This insect has a strong resemblance in form to Apis mellifica ; it

is altogether a most singular bee ; its situation in arrangement must,

I think, be between the genera Macropis and Andrena.
