gether. ( Oxystomus cylindricus, Dej. Spec. I. p. 410, of 

 Brazil). 



Camptodontus, Dej. 



In which the labial palpi are evidently shorter than the outer 

 maxillaries ; not bent, and terminated like them by a spindle- 

 formed articulation. The antennae are for the most part 

 composed of articulations, formed like reversed cones ; the 

 length of the first scarcely exceeds that of the two following 

 taken together. {Camptodontus Cayennensis, ib. II. 477-) 



The others, whose fore-legs are not indented on the outside, 

 but simply didactylous at the end, have short mandibles, 

 extending but little beyond the labrum, which is coriaceous 

 and entire ; the ligula extends beyond the emargination of 

 the chin, bare, or but little velvety, with separate protruding 

 membranaceous paraglossa. The outer palpi are terminated 

 by an oval articulation, pointed at the end. 



These Carabi are small, inhabit humid places, and are not 

 strangers to the northern regions. 



Clivina, Lat. 



Have three strong teeth on the outer side of both fore-legs, 

 and one on that of the two following.* 



Dyscuirius, Bon. Clivina, Dej. 



Which have at most mere indentations, and small indistinct 

 spines on the outer side of the two fore-legs ; this outer side 

 is in general elongated at its extremity into a long point, in 

 form of a spine or finger, and opposed by another finger, 

 formed by a strong spine on the inner side. The last articu- 

 lation of the labial palpi is, in proportion, thicker than the
