INSECTA. 



T)ie seuoiid tnlie, tliat of the Carohici, Latr., comprises the genus 



Cakabus, Linn., — 

 \Vli:c1i Iia> ilie ni;L\ill;o ienninared biiy)|i]\ in a point or Imok, not articulated at its ha^e. Tlie head is 

 geneially narrower, or at !ea:5t ncit broailcr, tiian the thi.irax ; the niarnhhlcs, except in a few instances, 

 arc destitute of or witli very shglit teeth ; the tnngiidet is generally exposed, and the labial palpi are 

 only disiineily liiri'e-joiiitrd, (the ha^al joint, which in Ciciiidela h detaclied, fnruung a fourth 

 joint, hemi^ here entirely \\\i-y\, jokI foniiing li sn[)[iort to the ])alpus, and is accordingly not reckoned 

 as a separate joint). Many sperlcs arc desUnueof \\irig^, and have oidy elytra. They often einit 

 a fetid odour, and discharge from the anu-> an aend and eau:>tie liquid. 



Geoffroy cons)idered that the ancients designated these insects under the name of Br/pres/is, and 

 which they regarded as a dangerous poison, especially to oxen. (See the genus Meloc). 



The Carahici conceal themselves in the earth, under stones, the hark of trees, &c., and are for tlic 

 most part very active. Their !ar\a: have the same habits. This tribe is very numerous, and of dilfi- 

 cnli investigation. 



We form a first general division v.'itli those in wliich tlic exterior [maxillary] p;ilpi arc not terminated 

 by a minute conical joint, the last joint forming, witli the preceding joint, an oval or conoid mass, 

 with a sliarj) point at its ti]). 



Slime of these ha\e a deep noh.'li on the inner edge of the anterior tibia?, separating the two acute 

 spurs, which arc unlinarily ])laced at the apex of the limb. These constitute several [live] sections."^ 



1. The TiiuNCATiPENNES, thus named from their el\tra licing almost invariably truncate at the 

 posterior extremity. The bead and thorax are narrower tlian the abdomen. Some iiave the ungues 

 of the tarsi simple, or without teeth beneath. Of these the three following are destitute of wings. 



Aiillna, Weber, F;ib., with the tong;ue]et homy, oval, and nearly as lon^ as the palpi ; the abdomen is oval, often 

 convex, ctnd the fl\ Ira aie rjcarly entire, or scarcely truncate. These, as well as tliose of the next subgenus, have 

 tlir IjDily I'hick, au'l with ^imts of \\\\\\ii dnwn. They inhabit tlie dosurts and other sandy jtlaces of Asia and 

 AlViea. Frnni an oliser\ iiticm of ]»(■ L;ttonr, they iji'ct from the anus, wlieii distuibixl, a Ciui--tic liquid. The 

 species are ^eriLTah)' of lar;;'e iiize, and in tlie males of some tlie tliurax is ddated more en" ic^s behind, and teniii- 

 nated by two lobes. 



Crapiiipterus, Latr. ion^: confounded with the pi'ecedinc;, l)ut diU'ering' in the ton^'uelet, entirely nienihranous 

 exeept in tlie centre ; the abdomen is always liattened and orliieular. The S|tecie.? of ttiis subj;eiius are exLJu^ively 

 African, and are much smaller than the precedin;^. 



J/>t/iiiis, Bonelli. has the last joint of the exterior palpi, and especially of the labial palpi, evidently dilated, and 

 a tuiith in the middle of the mentum. But that wliich more particularly distinj;uishes them, and also the Brnchini, 

 i.s, that tlieij- .nhdmncn, which is oval and thickened, contains organs which secrete a caustic (iaid. escaping," with an 

 ■■\|iIiiMMii finin the anus, and instantly evaporating-, with a penetrating; scent. I'his fluid, when the animal is held 

 Ketween the linji^ers, produces upon the skin a spot similar to that made by nitric acid, and e\"en, if the species be 

 lar^e, a painful burn. Dufour first made us acquainted with the organs by which it was secreted (iu .-iH/m^. rfw 

 Mils. fVm.st. Nat., tom.xvii.). These insects are often found assembled in societies, especially m the spring, 

 Under stoues. They make use of this defence to alarm their enemies, and they are able to repeat the explosion a 

 ciMi^iderjiblc nunibi-r of times. The larsrer spi;cies are found in the tropics ami other hot countries, as far as the 

 bunts of the teniperati; -/.one. A. Ji'i/i.sla, DeJ. (Bruc/ii/ms displusor, Dufuur), inhabits Navarre and variuu^ parts 

 of Hfjairi and Portugal.

 of I'uiis [as well as in various parts of Eii^;»-landj. It is i::enerally four hues loni;;, fulvous-oran;;-e, 

 ^\ith the elytra dark blue or greenish blue, arnl the antenna? fulvous, the third and fourth joints 

 beiuj^ black. The breast, with the exception of the middle uf the abdomen, is also fulvous. Other 

 speeies are named, from their explosive powers, B. bombania,B.i\r/ia(anfi,B.causticus,B.sclope(a,&:c. 

 {Cnfa-scopifx, Kirby, appears to us to belong- to the section Simplicimani, from a recent investi- 

 gation, rather than to this section.) 



Coy.s7/rff, Stev., is placed by Dejeaii between Brachinus and Catascopus. Tlie claws are simple ; 

 budyflat, short, broad; palpi filifnini- 



The other Carabiei of the same division have the undoes alsu simple, but the head is narrowed l.iebind the eyes 

 into a neck. In some the tarsi are marly identici.d in the two sexes, subcyhiidriral ur linear, (he peiiuhimate 

 juint being alone deeply bilobed.
