and, with the exception of the dilatation, nearly formed like the anterior. 

 These Carabici prefer sandy and hot localities. 

 Here we have, Jlcinopus, Daptus, Harpalus, &c. 



4. The SiMPLiciMAia approaches the preceding in the manner in which 

 the elytra are terminated; but the two anterior tarsi alone are dilated in the 

 males, without however forming a square or orbicular palette; sometimes 

 the three first joints are much wider, and in this case the succeeding one 

 is always smaller than its antecedent; sometimes the latter and the two pre- 

 ceding ones are larger, almost equal, and in the form of a reversed heart or 

 triangular: the first joints of the four following tarsi are more slender and 

 elongated, almost cylindrical, or in the form of an elongated and reversed 

 cone. 



The genera are Zabrus, Pogonus, Feronia, &c. 



5. The PATELtiMANi, distinguished from the Simplicimani, by the man- 

 ner 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 which are sometimes square, and at others only in part, the re- 

 mainder being cordiform, or resembling a reversed triangle, but always 

 rounded at their extremity, and not terminated as in the preceding sections 

 by acute angles, form an orbicular palette or long square, the inferior sur- 

 face of which is usually furnished with brushes or crowded papillae, without 

 any intermediate vacancy. 



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

 quently narrower than the abdomen, throughout its whole length. Most 

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



The genera are, Dolichus, Agonus, Chlsenius, Dicaelus, &c. &c. 



6. The GRANDIPAIPI, whose anterior tibiae have no emargination on the 

 internal side, or which present one that begins close to their extremity, or 

 that does not extend on their anterior face, and forming a mere oblique and 

 linear canal. The ligula is often extremely short, terminated in a point in 

 the middle of its summit, and accompanied by pointed paraglossae. The 

 mandibles are robust. The last joint of the exterior palpi is usually larger, 

 compressed into the form of a reversed triangle, or securiform in some, and 

 almost into that of a spoon in others. The eyes are prominent. The 

 elytra are entire or simply sinuous at their posterior extremity. The abdo- 

 men, compared with the other parts of the body, is voluminous. They are 

 generally large Insects, are ornamented with brilliant metallic colours, run 

 very fast, and are extremely carnivorous. 



In this section we have Pamborus, Cychrus, Scaphinotus, Procents, Cala- 

 soma and 



CARABTIS, Lin. Fab. 



Or Carabus properly so called. The labrum is simply emarginate or 

 bilobate; tooth of the emargination of the mentum entire.
