COLEOPTERA. 393 



Sphodrus, Clair. Bon. — LcEJiosxHENrs, Bon. — Carabus, Lin. 



The body depressed but not foliaceous ; head ovoid ; thorax cordi- 

 form; elytra without any exterior dilatation or internal emargination. 



Several of these Insects live in cellars *. 



The last of the Simplicimani are distinguished from all the others 

 by the internal dentations of the terminal hooks of their tarsi. 



All the exterior palpi, of some, are filiform ; their thorax is either 

 in the form of a heart, narrowed and truncated posteriorly, or in 

 that of a trapezium widening from before backwards. 



Ctenipus, Lat. (a) — Lcemosthenup, Bon. 



The body straight and elongated, thorax cordiform, narrowed and 

 truncated posteriorly; third joint of the antennae elongated \. 



CaLATHUS ^072. 



The body oval and arcuated above ; thorax square or trapezoidal, 

 wider posteriorly |. 



The labial palpi of the others have a clavate termination, in the 

 form of a top or reversed cone, and a nearly orbicular thorax. 



Taphria, Bon. — Synuchus, Gyll. 

 Emargination of the mentum bidentate, as in the preceding sub- 

 genera §. 



5. The fifth section, that of the Patelltmani, is only distinguished 

 from the fourth, by the manner in which the two anterior tarsi of the 

 males are dilated ; the first joints — usually the three first, then the 

 fourth, and sometimes only the two first — all of whicli are sometimes 

 square, and at others only in part, the remainder being cordiform, 

 or resembling a reversed triangle, but always rounded at their extre- 

 mity, and not terminated as in the preceding sections by acute an- 

 gles, form an orbicular palette or long square, the inferior surface of 

 which is usually furnished with brushes or crowded papillae, Avithout 

 any intermediate vacancy. 



The legs are generally slender and elongated, and the thorax is 

 frequently narrower than the abdomen, throughout its whole length. 

 Most of them frequent the shores of rivers, or other aquatic localities.

 XI, 4. In the Sphodrus terricola — Carabus terricola, Payk. ; Oliv., Col. Ill, XXXV, 

 ii, 124 — the hooks of the tarsi present some small dentations, as in the following 

 subgenus. 



-f- The Sphodri janthinus, complanaius, and several others of Count Dejean, which 

 are distinguished from the true Sphodri by the abbreviation of the third joint of the 

 antennae, and by the dentations of the hooks of the tarsi. These two subgenera are 

 almost insensibly confounded with each other. M. Fischer has figured several spe- 

 cies of both under the generic appellation of Sphodrus in his Entom. Russ. Vol. II.
