2^0 CLASS INSECTA. 



tively to the other parts of the body. These carabici are for 

 the most part of large size, ornamented with brilliant metallic 

 colours, run very fast, and are extremely carnivorous. They 

 will compose a peculiar section, the sixth of the genus, and 

 which we shall name Grandipalpi, a denomination more 

 characteristic than that of abdominales, which we formerly 

 applied to it. 



A first division will have for characters, the body always 

 thick, without wings ; labrum always bilobate ; last articu- 

 lation of the external palpi always very large ; emargination 

 of the chin without tooth ; internal side of the mandibles 

 entirely, or almost entirely denticulated in its length. 



In some the mandibles are arched, strongly denticulated in 

 all their length, and the lateral external extremity of the first 

 two legs is prolonged into a point. The last articulation 

 of the external palpi is a semi-oval longitudinal, with the 

 internal side arched. The internal maxillary palpi are 

 straight, with the last articulation much larger than the first, 

 and almost ovoid. The emargination of the chin is of no 

 great depth. Such are the characters of 



Pamborus, Lat. 



But a single species is known {Pamborus alternans), Cuv. 

 Reg. An. V. xiv. 2, Dej. Spec. TI. 18, 19, and which was 

 brought from New Holland by M. M. Peron and Lesueur, 



In others the mandibles are straight, simply arched, or 

 crooked, and dilated at their extremity. The two anterior 

 legs are not prolonged in the manner of a spine at their la- 

 teral extremity. The last articulation of the external palpi 

 is much larger than the preceding, concave above, almost in 

 the form of a spoon. The chin is profoundly emarginated, 

 proportionally more elongated than in the following sub- 

 genera, thick on the sides in most of them, and as it were 

 divided longitudinally into three spaces. The elytra are
