14 This subgenus differs from Anepsiola in having the infra-lateral carinæ of the head very strongly developed and entire; the abdomen is narrower and is not always parallel. The middle coxæ are contiguous, the mesosternal process acutely angular or prolonged and aciculate, and the metasternal extremely short, very broadly angulate. One of its most salient characters is the very long basal joint of the hind tarsi, so unusual a character in Atheta, this joint being fully as long as the next two combined throughout. The three species at present assignable are as follows:

The tapering form of the abdomen is remarkably exceptional in the true Athetæ and this character alone will serve to isolate this species from its fellows; the infra-lateral carinæ are very strong and are entire.
