CARABIDAE. 29 



TncJnjpus is, however, capable of feeble definition, but the 

 general appearance of the species is so distinct that it seems 

 preferable to retain it. 



TacJnjs and Fo'icompsus should proljabl}' be united, the ciiu- 

 racters separating the latter being rather those of a group of 

 species than a genus. 



Tribe XVII.— POGOIVINI. 



Antennie slender, arising under a feeble frontal ridge ; the third 

 joint usually very little longer than the second, the first two joints
