190 CLASS INSECTA. 



Sometimes the external palpi are terminated by a thicker 

 articulation, in the form of a reversed or triangular cone. 

 The head, immediately after the eyes, is abruptly narrowed, 

 and of a triangular form, or that of a heart. 



Some, whose body is flatted, and which Fabricius has 

 placed with his galeritae, have all the articulations of the 

 tarsi entire, the corslet in the form of a heart truncated pos- 

 teriorly, and the mandibles, as well aa the jaws, of the 

 ordinary length, or but moderately prominent. 



The first articulation of the antennae is in the form of a 

 reversed, and elongated cone. The tongue is squared, and its 

 lateral divisions are often as long as itself. A tooth is per- 

 ceptible in the middle of the emargination of the mentum. 

 These carabici, whose indigenous species are found under 

 stones, the barks of trees, and most frequently in the 

 neighbourhood of waters, form the following three sub- 

 genera : —

In which, as in the following sub-genus, the first articula- 

 tion of the antennae is shorter than the head, and in which 

 the maxillary palpi are of the usual length ; but the second, 

 third, and fourth articulations of the tarsi, those of the 

 anterior two especially, are short, almost orbicular, and the 

 tongue is terminated superiorly by a straight edge, has its
