282 CLASS INSECTA. 



The second division of this section contains carabici, having, 

 like the preceding, the body thick, most frequently without 

 wings, but the chin is furnished, in the middle of its emargi- 

 nation, with an entire or a bifid tooth, and the mandibles are, 

 at the most, armed with one or two teeth, situated at their 

 base. 



The corslet is always in the form of a truncated heart. 

 The abdomen is most frequently ovaliform. 



Some, the labrum of which is occasionally entire, have all 

 the tarsi identical in the two sexes. 



Tefflus, Leach, 



Are the only ones of this division of which the labrum is 

 entire, or without emargination. 



Tefflus of Megerle (Carabus Megerlei, Fab. Voet. col. 

 II. xxxix. 49) is about two inches long, and inhabits the 

 coast of Guinea, and the eastern extremity of the Senegal. 

 It is altogether black, with the corslet wrinkled, and the 

 elytra divided by longitudinal ribs, and having raised points 

 in their furrows. The last articulation of the external palpi 

 is very large, in the form of an elongated hatchet, with the 

 internal side curvilinear. The tooth of the emargination is 

 very small. The third articulation of the antennae is at 

 least three times longer than the second. 



Procerus, Meg. 



Have the labrum bilobate. All the known species are equally 

 of a large size, either entirely black, or of that colour under- 

 neath, and blue or greenish above, with the elytra very much 

 chagreened. They generally inhabit the mountains of the 

 eastern and southern countries of Europe, and those of the 

 Caucasus and Mount Libanus.*
