COLEOPTERA. 299 



Those, in which the body forms a long or cylindrical square, 

 "where the thorax is almost square, hardly narrower behind than 

 before, form the genus Cophosus of Ziegler and Dejean. It was 

 established on an Austrian species, the C. cylindrkns(l). 



Those in which the body is generally oval, depressed, or but 

 slightly concave above, with a wide, nearly square, and subisomet- 

 rical thorax, whose lateral margin is always strongly reflected, and 

 is as wide, or nearly as wide, at its posterior margin as the base of 

 the elytra, compose the genus Max of Bonelli. 



Several species are found in Germany. The one called the me- 

 tallicus, and the Molops striolatus, Dej. whose antennae are composed 

 of shorter joints, or are nearly granose, have been formed into a new 

 genus, styled Cheporus(2). 



The F. striola; Carabus striola, Fab.; Carabus depressus, Oliv., 

 Col. Ill, 35; IV, 46, is often found in the cold or humid locali- 

 ties of the forests in the environs of Paris(S). 



Sometimes the thorax, always terminated posteriorly by two well 

 marked or acute angles, is evidently narrowed behind. Its figure 

 approaches more or less to that of a truncated heart. 



Of these species, several have the body depressed or plane above, 

 and the antennae composed of elongated joints, rather obconical than 

 turbinated. They are distinguished generally by Bonelli under the 

 genuine name of Pterostichus. They more particularly inhabit the 

 high mountains of Europe, and Caucasus. 



But a single species Carabus oblongo-punctatus, Fab.; Panz., 

 Faun. Insect. Germ., LXXIII, 2 is found in the environs of 

 Paris(4). 



Others, whose antennae are almost granose, have the body convex 

 above, and proportionably wider, with a shorter abdomen. They 

 form the genus Molops, Bonelli, which evidently leads to other very 

 analogous Feroniae, but where the posterior angles of the thorax are 

 rounded, and the abdomen oval, the exterior angle of the base of the 

 elytra being obtuse or non-salient. The body and antennae are, in 



(1) We will add to it the Omaseus melanarius, Dej., as well as another species 

 Of Germany intermediate between the preceding ones and the Cophosus cylindricus, 

 and which, I think, is the Omaseus elongatus, Ziegler. 



(2) The Platysmse described and figured by M. Fischer Entom. Russ., II, 

 xix, 4, 5; are probably analogous Abaces. 



(3) For the other species, see the Catalogue of Count Dejean, and the Faun. 

 Aust. of Duftschmid. 



(4) For the other species see Dejean's Catalogue and the Entom. Russ., Fischer, 

 U, p. 123, xix, f. 1; xxxvii, 8, 9. I coincide with the opinion of the latter, that 

 the G. myosodus, Meg., does not essentially differ from Pterostichus.
