4^3G TNSECTA. 



semiorbicular, scparatcrl from tlic alxlomcn by an interval, ^vhich makes it appear pednnculatcrl ; the 

 legs are generally but sliglitly elnn'/ated, with the tarsi often short, alike or scarcely different in the 

 two sexes, \vith(nit a cushion on the under-side, and merely furnished with the ordinary hairs or cilife ; 

 tlie two anterior tibire are toothed on the outside, as though palmated, or furnished with fingers, in 

 many species, and the mandibles are often strong and toothed ; the notch of the mentum is armed 

 \vith a tooth. They are all found on the ground, hiding themselves either in burrows which thfiy have 

 dug, or under stones, and often quitting their retreats only during the night ; their colour is generally of 

 an uniform black. The larva of Ditomus lucephalus, the only one yet observed, has the form and 

 mode of life of the Cicindela'. They are i>art.icularly natives of hot climates. 



The three foUowinLC siihi,'-enera have the hibial palpi terminated by a lor^e hatchet-shaped joint. 



Encdadas, Bou., has tlie anterior tibije without any internal notch, and not palmated externally. The thorax 

 is lieart-shaped, broadly truncated. Type, E. gigas, Bon., from the coast of Ans"oIa. 



.Siagona, Lat. (Cncujus and Galerila, Fabr.), has the fore tibire not palmated, but the notch on the inside is 

 distinct; the basQl joint of the antennas is elongated. Some species have the abdomen oval, and are apterous 

 {S. ntjipes, &c.)- In otliers, it is oval, truucatcd at the b.ise, and these species are wing-ed. Tliey inhabit northern 

 Africa or the East Indies. 



Careiit/m, Bon., has the antennrc moniiiform, the anterior tibia? toothed on the outside, thus resembling 

 Scarites ; the maxillEE are straight, without ,'my tern^ina! tooth. Type, Scar, ci/aneus, Fabr., from New Holland. 



All the remaining Scaritides have the labial palpi temnnatedby an elongated, nearly cylindrical joint, narrowed 

 at the base ; the last joint of the maxillary palpi is also subcylindrical. 



A first very natural subdivision comprises the Scarites of Fabricius (except the last-mentioned species), which 

 have the two fore-legs palmated or lingered at the tip, that is, terminated exteriorly in a long point or spine, 

 opposed to a very stront^ inner spur. The antennae are monihform, with the second joint as long and often longer 

 than the following. The mandibles are robust, advanced, and toothed on the inside. 



Some of these have the mandibles very strong, protruded, and toothed, tlie upper lip crustnceoas, and very much 

 toothed on the fore margin ; the fore tibiae are always palmated, and the species are genej-ally of large size. 



Pui'inac/tus, Bon., approaches the last in respect to flie maxilla.-, which are straight, and without any terminal 

 hnok ; the body is very flat, thorax heart-shaped, broadly truncate behind. This subgenus is confined to 

 AiLiei'ica. 



."-^I'ljifcrus Dej., is plac-d by its author next the preceding, but the form of the body is lone; and cylin- 

 driral. I do not, howevf-r, know if tlie maxillae are similar. It is fijimded upon a species from the liast 

 Indies, named Scapteru-s dirrrhi?. 



The following have the maxilla; arched and hooked at the tip ; the thorax is always separated behind from the 

 base of the elytra by a decided space. 



The three following subgenera are distinguished by the extiTual palpi bciuL^ terminated by a nearly cylindj-ieal 

 joint, not narrowed at tip. 



AcaidhoscdiSy Latr. (distinguished by the four posterior curved and flattened tibix, covered with minute points ; 

 Type, Scarites rujlcornis, Fabr. ; an inhabitant of the Cape of Good Hope. 



.Sca/'i/i?^, Fabr. (having the four hind tibis straight and naked, the mandibles ot a triangular furm, strongly 

 tooLlied at the base). Type, Scarife.f ryracmon, Bon. {Sc. gigas, Oliv.) ; about one inch \o\v^, found on the shores 

 of the Mediterranean, the south of France, &c. ; Scarites terricola, Bon., found with the preceding; Scarites 



s,ihnlo.sits; Oliv., &C. 



Ot II III! nihil-:, Iti'j., essentiady like Scarites, but with Inn,^, narrow mandibles, wuthout teeth, closing like a pair 

 of pincers, and Uie body hui.c;, narrow, and cylindrical. Type, ScarUcs clongatnsy AViedenian ; an inlmbitant of the 



Fast Indies. 



Oxiisiomus, Latr. (with the labial palpi nearly as loii;2; as the outer maxillary, with the last joint spindle-sltaped, 

 —type, '0. ci//indricus, Dej., Brazil) ; and Camplodonlus, Dej. (with the labial palpi considerably shorter tli;iii tlie 

 outer maxillary, with the last joint spindle-shaped,— type, C. cai/ennensi-s; Dej.). are both distinguished by their 

 elongated, cylindrical body, and long, narrow, toothless mandibles. 



The others h.avc the anterior tibioe not dentated on the outer edge, but .simply didactyte at the tip ; the man- 

 dibles short but slightly advanced beyond the labruni, which is coriaceous and entire, and the outer palpi termi- 

 nated by an oval joint, sharpened at the tip. They are of small size, frequent damp places, and occur in our 



northern regions. 



Clivina Latr., has three stronir teeth on tin' outer edu^e of the two aulerior tibia?, and one on that of the two 

 followin"-. Type, Tenchrio fosfior,hm.i {Scirife.-.- arvinuhis, Fabr.). [A very common British species, about a 

 qnarter of an inch long. J 



fjiiac/iiriiis, lion.j which has only small teeth or small indistinct spines on the outer edge of the two anterior 

 tibite the tip of which is produced into a long point ; the thorax is nearly globose. The Cliviiuc, Nos. S— '.'1 of 

 Deiean but the eighth, or G. arcf/ca, appears to possess the characters of Cephalotes. [These species, of w hich 

 7) aibbus is the type, are amongst the most minute of the Carabidce; the species are rather numerous, and 

 verv difficult to be determined. The C. arcttca has been formed by Eschscholtz into the genus Miscodera 

 (Ldochito/1, Curtis, Onr.odcrus, Stephens), and belon-'s, as Latreille indicates, to the fanuly Harpalida\] 



Our second and lust subdivision of the Scaritides comprises those which have the antenur tibi;e neither
