CLASS INSECTA, 



plane above, and the antennae composed of articulations to- 

 lerably elongated, rather obconic than turbinated. M. Bo- 

 nelli distinguishes them generically under the name of 

 Pterostichus. 



They more particularly inhabit the high mountains of 

 Europe and the Caucasus. 



The environs of Paris furnish but a single species {Cara- 

 hus oblongo-punctatus, Fab. Panz. Faun. Insect. Germ. 

 LXX. iii. 2). 



I think with M. Fischer, that the genus 7nyosodus of M, 

 Megerle does not differ essentially from that of Pterostichus. 



Others, whose antennae are almost grained, have the 

 upper part of the body rather convex and proportionally 

 broader, and the abdomen shorter. It is the genus molops 

 of M. Bonelli, which evidently conducts to other very 

 analogous feroniae, but whose corslet is rounded at the pos- 

 terior angles, and whose abdomen is ovaliform, the external 

 angle of the base of the elytra being obtuse or not salient. 

 The body and the antennae are in general proportionally 

 longer. These last species have been detached from Pteros- 

 tichus to form a new genus, that of Steropus, Meg.* 



We shall terminate, in fine, this sub-genus with some 

 species generally rather large, whose corslet has almost 

 always the form of a truncated heart, and of which the base 

 of the elytra has no transverse fold, or presents at most but 



• See as well for this as the preceding, the Catalogue of M. le 

 Comte Dejean, and M. Germar (Insect. Spec. Nov. I. p. 26, et seq.). 

 Some species, such as Molops terricola {Scarites piceus, Panz. Faun. Insect. 

 Germ. XI. 2). Molops elatus {Scarites gagates, ejusd. XF). Steropus hot- 

 tentota {Scarites hottentota. Oliv. Col. III. 36, 11. IQ,") have been ranged 

 with scarites. Carabiis viadidus, of Fabricius, a species common enough 

 in some southern departments, is a steropus. M. le Comte Dejean forms 

 a new genus with Sc. Hottentot, in consequence of its anterior feet, the 

 legs of which are arched, and of some other characters.
