XXVII. A Century of Insects, including several new Genera described from his Cabinet. By the Rev. William Kirby, M.A. F.R. and L.S.

Read November 4, 1817*

\

.The infinite host of non-descript insects occurring in the entomological cabinets of this country, is rather disgraceful to us : and what is more so, we permit foreigners to do that for us which we are fully competent to do ourselves. Witness the numbers described by Fabricius, Olivier, and others from British collections.

Pudet hæc opprobria nobis Et dici potnisse et non potuisse refelli..

I am not, however, so illiberal as to wish that the entomologists of the continent should be excluded from our cabinets : if we ourselves are too idle, or too busy, to give the public some account of our entomological treasures, it is for the interest of science that they should do it for us.    •

To remove, in some degree, this opprobrium, I beg leave to offer to the Linnean Society descriptions of a century of the nondescript insects of my own cabinet. Should this attempt meet with approbation, I may be induced, perhaps, to decribe the remainder; and I wish that my example may stimulate other gentlemen to do the same with respect to their own collections.

In my general arrangement I have followed that of my kind

and

and learned friend M. Latreille, in adhering to which I have round that my cabinet contained many insects that could not well be placed in any of his present genera. These I have named and characterized.

COLEOPTERA pentamera.

M. Carolina simillima, sed minus nitida. Thorax dorso nigrescit. Elytra nigra: margine laterali tantum viridi; macula apicis lineari rufa, nec apex ipse pallidus ut in ilia.

The comparative length of the maxillary and labial palpi, upon which this genus is built, seems to me, in this case especially, to indicate a family rather than a genus. The labrum, however, is of a different shape from that of most other Cicindelidce.

* By this term Mr. Spence and myself have distinguished that part of the body in which the four posterior legs are inserted.

f By this term we designate that part of the elytrum that is under the lateral margin, which often covers the sides of the body, and is remarkable in many Heteromerous insects.

This

This genus is distinguished from all others of the tribe by the tonfi ot its labrum, and of the last joint of the palpi. It should be placed at the end of Latreille’s fifth section, between Pana-gau§ and Cychrus *.

At first I mistook this beautiful insect for B. cquestris Fabr. ; but the terms—Corpus ceneum—sterno parum porrecto—Elytra punctorum duorum par, by no means agreed with it : and when 1 further compared it with Olivier's B. hamorrlioidalis, to which Fa-bricius refers as synonymous with his B. equestris, I was fully convinced that they were distinct species ; since from Olivier's figure it appears that B. hcemorrhoidalis is little more than half the size of B.jucunda; and in the former the three last ventral segments of the abdomen are red, whereas in the latter they are green

These two insects seem nearly allied to three species of Fabri-cius, E. suturalis, bicornis, and vespertinus; but at the same time they appear to be quite distinct from them. From the first they are sufficiently distinguished by having no lateral thoracic tooth or spine; from the second in their colour, E. bicornis being entirely black; and from the third in the colour of their head and antennae. From the different shape of the last joint of their palpi, and from the remarkable pair of impressions on the anal segment of the underside of the abdomen, these insects should form a distinct family, if not a distinct genus.

This genus connects Latreille's tribe ofCebrionitcs^CebrionidceK.) with the Elateridce. It differs from all the present genera of that tribe in its moniliform antennae and short palpi, and more especial^ in having its labrum quite concealed by the clypeus. From Elattr, which in habit it most resembles, it is distinguished not only by these circumstances, but also by its protended mandibles and deflexed sternum.

The Brasil species of this genus vary from those of New Holland (one of which I shall hereafter have occasion to describe) in having only one tooth near the inner base of each mandible; whereas in the latter there are two. The last joint of the palpi of this is cylindrical, while in R. marginata it is subovate or ovato-lanceolate. Hence may be formed two natural families in the genus, * Mandibulis intus unidentatis ; ** Mandibulis intus biden-tatis.

I exclude from this tribe two genera placed in it by Latreille, (Mastigus Hoff, and Scydmanus Latr.), but which, having little affinity with it, had better stand by themselves, and then divide it into two sections : the first containing those with serrated antennae (serricornes), and the second those with clavated (clavicornes).

Latreille’s character of Tillus in Cuvier’s Regne Animal *, “od la majeure partie des antennes est en forme de scie, et ou les tarses, vus sur les deux faces, ont cinque articles tres-apparens,’would include the four genera I have here defined. But the other characters exhibited by them, both as to their habit and general form, and their oral instruments, are so different, that every entomologist who at all adopts that learned author’s system would consider them as good genera. Thus in Bury pus and Tillus the labrum is entire, while in Axina and Priocera it is emarginate. Again, the labium in Tillus is entire, but in the three other genera bifid. In Eurypus and Axina all the palpi terminate in a securiform joint; in Tillus and Priocera, only the labial ones. In Eurypus and Priocera the maxillary palpi consist of four joints; in Tillus and Axina, only of three. In Eurypus, Tillus, and Axina the labial palpi are biarticulate, but in Priocera they are inarticulate. In Eurypus the thorax is square; in Tillus and Axina* cylindrical; and in Priocera, constricted behind*

This species is nearly related to C. splendidiilus and conspicil-latus Fabr. From the former it is distinguished not only by having the horn on the head flattened instead of compressed at its apex, but the thoracic horns are narrower and more elevated, and the fovea does not extend the whole length of the thorax : besides, in C. splendidiilus the horn terminates near the anterior margin of the thorax in a prominent tooth, which is wanting in C. floriger. C. conspicillatus is also a native of Brasil ; but the thorax of this is very retuse anteriorly, and armed with two teeth only, which is not the case with the insect I have described. The insects in question, with several other species, vary from Copris in their antennae and some other characters, and form a connecting link between Quit is and that genus.

I have given the characters of Anoplognathus, as well as of the two genera 1 have here established, that I might afford a clearer view of those particulars in which they differ, in order that the claim of the latter to be considered as distinct, genera may be more readily perceived. In habit and external appearance they certainly appear very unlike each other; but their oral organs are upon the whole so similar, that from these they might perhaps be thought to belong to the same genus, and be well arranged under Anoplognathus. A near view of them, however, will I trust justify me for giving them as distinct.

In the first place, Anoplognathus is distinguished, besides its general habit which at first sight appears different, from both Geniates and Apogonia by the remarkable protended conical poststernum observable in all the species of that genus; in the next, by having all its claws simple and undivided ; in this respect resembling Rutela. Its labium also is of a different shape, unless it may be regarded as connate with the mentum. From Geniates it differs in having maxillae without teeth at the end and very concave, and, which is important, its antennae have one more joint. Those remarkable circumstances, peculiar to the males of Geniates, of a stiffly-bearded mentum and dilated anterior tarsi, furnish also a striking distinction. From Apogonia it may be

known

known not only by the particulars before noticed, but also by its transverse lahrum, its entire and very concave maxillae, and by the elytra covering all the joints of the upper side of the abdomen but the last; whereas in Apogonia the two last joints are uncovered. Genintes may be distinguished from Apogonia not only by this last circumstance, in which it agrees with Anoplognathns, but also by having a transverse labrum, maxillae armed with three teeth, by the insertion of its head, which is inclined towards the horizon, whereas in Apogonia it is nearly vertical, by having a joint less in its antennae, by the beard on its chin, and remarkable dilated anterior tarsi before noticed, by having only its exterior claw, and not both, bifid at the apex; and lastly, by the remarkable thumblike process at the base of the inner anterior claw.

Another insect in my cabinet, which I regard as Melolontha ruficollis Fabr., but which comes from Brazil, is distinguished by dilated anterior tarsi, and may perhaps belong to this genus, its labrum, however, is triangular, with the vertical angle emarginate, and the acumen of the labium is also emarginate; in other respects its oral instruments agree with those of Geniatcs.

The species here described agrees in many respects with Fabri-cius’s description of Melolontha geminata; but the term “caput laeve” at once indicates their difference, since in my insect the head as well as the thorax is thickly covered with deeply-impressed

points.

This species differs from the other Lucani in having a bifid mentum, recurved mandibulae (in which it agrees with Lamprima Latr.), and palpi with curved articulations; but its broken antennae with a pectinated clava, and depressed body, prove that it is more nearly related to Lucanus than to Lamprima, in which the body is more convex, the antennae unbroken with a lamellated clava. It seems scarcely entitled to be considered as distinct from Lucanus; but at any rate it forms a family in that genus.

This genus is intermediate between Pimelia and Tentyria: from the former it is distinguished by its bifid labium, by its quadrangular mentum, narrowest below so as not to cover the base of the maxillae, and by its long, slender, clavate antennae; and from the latter, besides these characters, by its emarginate labrum. It is to be observed, that in this latter organ Pimelia muricata and his-pida differ from each other, as well as in their antennae, and the form of their bodies; hence the genus might be divided into two families, * Corpore subgloboso, ** Corpore oblongo.

The shape of the head and thorax also is different. The insect is so minute that 1 have not been able to get a clear idea of the shape of the labium and meat urn, but I think the latter is trapeziform.

I sent a sketch of an insect of this genus to M. Latreille, and he was of opinion that it belonged to a genus he had constructed, but which is not yet published, under the name of Orthorhynchus. I have since been informed by him, that the type of that genus is Lixus semipunctatus Fabr., which from Olivier’s figure appears to be more nearly related to Lixus bidentatus of Mr. Donovan, and is distinguished by acuminated elytra and filiform antennae; whereas no species of Eurhinus, and there are several, has acuminated elytra, and the antennae terminate in an oblong clava, the last joint of which, in the males, is very long. Olivier describes Lixus semipunctatus as antennis moniliformibus vix extrorsum cras-sioribus (v. 242. n. 242. t. xii./. 141.) In L. bidentatus the antennae are not moniliformes, but they are extrorsum vix crassiores. So that Orthorhynchus seems to be a connecting link between Eurhynus, the antennae of which are submoniliform at the base, and Lixus bidentatus, but belonging to the same genus with the latter. There are several species of Orthorhynchus in Mr. Mac-Leay’s rich cabinet. As Lixus semipunctatus is in the Banksian cabinet, it may be easily ascertained whether these observations are correct or not.

This species, as well as that which precedes it, would in a modern system doubtless form two genera, from the remarkable difference in their mandibles.

This insect, as well as Lamia Scorpio, exhibits a most extraordinary character; the terminal joint ot the antennae exactly resembles

bles a claw, such as arms the tarsi of many insects. This character, perhaps, would indicate a separate genus, but in every other respect these are true Camice. What may be the use of this claw is not ascertained; it is probably for the purpose of laying hold of surfaces.

This insect, which I purchased from the late Mr. Drury's col» lection, appears to vary both from Alurnus and Hispa, and might perhaps constitute a new genus; but as my specimen has no an^ tenme, I have for the present considered it as an Alurnus.

This species seems to differ from the others of the genus in the structure of its labial palpi, since they are not at all furcated. Whether the other species have the sutures denticulated I do not know, having only this species of the genus. Olivier does not notice it. The circumstance is so unique and remarkable, that if they have it not, it would indicate that C. Bacca belongs to a distinct genus.

-After repeated examinations under a powerful magnifier, I have not been able clearly to discover more than three joints in the tarsi of this insect; but Mr. Curtis in one tarsus detected four. Indeed its general habit, &c. connect it with the Tetramera, especially Cis and Cryptocephalus: it will not however well arrange under any of the present families of that section of Coleóptera; I have therefore considered it as the type of a new one, to which some other nondescript genera in my cabinet belong.

This genus belongs to Latreillc's Arachnides Trachéennes Hole-très, and should come before Phalangiiun, to which it is nearly related. It is sufficiently distinguished from that genus by its triangular body, immense posterior coxæ coalite with the postpec-tus and scarcely separated from it, except anteriorly, even by an impressed line; and more particularly by not having more than eleven joints in any of its tarsi. The third joint of the tibiæ may by some perhaps be regarded as the first joint of the tarsus, but vol. xii.    3 n    the

the spurs which arm its apex sufficiently prove that it belongs to the tibiae. The knees of the liind-legs of these extraordinary insects converge; and being armed with spines, seem adapted to catch or retain their prey ; and probably on this account it is that tiie coxae of these legs are so strong.

It seems to me that this genus and Phalangium, instead of coming after the Pycnogonidce, as Latreille has arranged them, should precede those marine animals, since their affinity to the spider tribe, scorpions, &c., is much greater.

XXViII. A Description of several new Species of Insects collected in New Holland by Robert Brown, Esq. F.R.S. Lib. Linn. Soc. By the Rev. William Kirby, M.A. F.R.and L.S.

Read February 17, 1818.

No country lias produced more novelties in every department of Natural History than New Holland ; and the plants and animals of that insular continent, if I may so speak, are most of them of a peculiar character. Even such as are most nearly related to those of other climates usually exhibit some diagnostic that separates them from their correlatives, and indicates the region that gave them birth. Thus, the Rhipicerce of New Holland are distinguished from those of South America by the teeth that arm the inside of their mandibles : their Lucani, (L. nebulosus Kirby, at least,) from those of other countries by their recurved mandibles and emarginate mentum. Not to mention the differences that separate Anoplognatlius from Geniates and Rutela, or Scarabeeus proboscideus from its affinities Sc. mobilicornis, quadridens, See.

Mr. Brown, (who has so ably illustrated the Flora of New Holland, and whose observations and discoveries have diffused so much new light over the science of Botany,) when in that country did not overlook its zoological productions, and amongst other subjects collected many new and singular species of insects. Desirous of having these treasures described, and his time and attention,—to the great benefit of the botanical *orld,—being devoted voted to another science; though fully competent to the task himself, he has requested me to layr a description of them before the Linnean Society, which I shall now do to the best of my ability, adhering to the plan begun in my former paper.

These two sets of characters are designed to point out the differences between two distinct families of Scarabceidce that have hitherto been considered as belonging to the same genus. Sc. mo-bilicornis Linn, (of which Sc. testaceus Fabr. is only a variety), qua-dridens Linn.,farctus Fabr., Lazarus Fabr., Cyclops Oliv. &c., belong to one of these families; and Sc. Typhceus Linn., dispar labr., Momus Fabr., stercorarius Linn., foveatus Marsh., Mutator Marsh., splendidus Fabr., sylvaticus Fabr., hemisphcericus Oliv., and verna-

lis Linn., &c. to the other. Whoever considers these characters, and compares these sets of insects with each other, will be immediately convinced that, according to the modern system, they ought to constitute different genera. The mandibula of one side (in some the right-hand one and in others the left) bidentate at the apex ; maxillae with the outer lobe truncated at the apex, the inner angle acuminate, and narrowest at the base, and ciliated ; the quadrate entire mentum; and above all the compressed, orbiculate, shining, punctate, hairy clava of their antennae, the exterior lamellae of which usually inclose the intermediate one as entirely as the valves of a bivalve shell the animal which inhabits it, distinguish the former of these tribes, to which I have long given the generic name of Bolboceras; whereas the other, the true Geotrupes, or earth-borer, is remarkable for mandibulae without teeth ; maxillae with a prismatic exterior lobe terminating in a brush of stiff dense hairs; an orbicular deeply-emarginate mentum; labium with rounded lobes; and antennae with a subovate clava, the third joint of which is always apparent, and all its joints exhibiting a downy appearance, but having no hairs. The body of the former also is more hemispherical than that of the latter, and the clypeus is not rhomboidal.

Geotrupes vernalis seems to connect these two genera; its body approaching to an hemispherical form; its labrurn, though not emarginate, terminating in a concave line; and its mandibulas having two teeth at the end. It differs from both in having the interior tooth the shortest, and the exterior edge of the mandible sinuate. In most other respects it agrees with G. stercorarius, Sec. In Bolboceras Cephus the middle joint of the clava of the antennas is not so wholly shut up between the two exterior ones as to be entirely hidden by them. In other respects it agrees with the rest. My details of Bolboceras were taken from B. quadridens,

3 o ‘2    and

and those of Geotrupes from G. stercorarins. I shall now describe a new species of the former genus from Mr. Brown’s collection.

Not being able to come at the trophi (Instrumenta cibaria Fabr.) of this insect, I cannot clearly ascertain whether it belongs to Trox or Melolontha. Its habit, stature, and closed mouth are nearly those of the former genus; but the first joint of the antennae is not hairy as in that, its abdomen not vaulted and flat, and the anterior pair of tibiae are not without teeth.

I did not discover that Adelium caraboides had been described by Fabricius till after the figures illustrative of this paper were drawn ; and as the insect here given confirms the genus I had laid down in my former paper, and is another instance of its species imitating the form and appearance of the Carabidce, I think it may be interesting to Entomologists, particularly on account of Mr. Curtis's excellent figure, if I retain it. I have altered Fabricius's trivial name, as the insect certainly is neither a Cara-bus nor a Calosoma, to make it harmonize with those of the species before described.

This family of the genus Helceus presents some of the most singular insects in nature. The lobes of the thorax meet over the vol. xii.    3 p    head,

bead, and by their union, by means of a sinus cut out of their inner side, form a round hole where the vertex of the head appears and part of the eyes, so that the animal is thus enabled to see things above it as well as below it. The anterior part of the head is below the thorax.

I know no insect amongst the Curculzonida (except one of the same tribe with this in Mr. MacLeay's cabinet with an anal forceps, something like that of an earwig,) that is so wonderfully formed as the species here described. The ventral cavity, laminin, and pecten have no parallel that I am aware of in the insect world. These organs are probably for sexual purposes, since the other sex, if I am not mistaken in supposing the variety I have described merely sexual, is without them.

This genus, named long ago, as above, by Mr. MacLeay, connects Cerambyx with Mo lor chas, Keep da lis, and Rhagium. With the latter indeed it has little other connexion than from the similar shape of its elytra, which grow gradually narrower towards the apex ; from Cerambyx it is distinguished by its antenme; and from Molorchus and Necydalis by its elytra, scarcely at all shorter than the wings, and by its disticho-ramose antennae.

This species approaches very near to Stencorus suturalis of Olivier (iv. no. 6'9- 29- 25. t. 3. f. 29.); but in his insect’ the legs are black, the thorax has only two tubercles, and the base of the exterior margin as well as that of the suture is violet; whereas in L. ceramboides the legs are red, the thorax has four tubercles, and only the suture is violet. His insect also comes from a different-country, being a native of the East Indies. These two species form a distinct section of Leptura, or perhaps a new genus..

The situation of the antennae of the insect from which I have formed this genus, agrees with that of Fulgor a; but in all the genuine species of the latter their second joint is much larger than the first, globose, and covered with papillae : whereas in A chillis it is not remarkably larger than the first, is rather tapering, and without papillae. The labrum also is not separated from the clypeus, except on the sides, by any suture or even impressed line; the thorax a good deal resembles that of Fulgor a, but it is more completely obtusangular.
