Hoplocephala.

40S. H. caviis. Elongatns cylindricus, piceua Ditidns, hand dense 

 punctatns, pilis Longia helvis parce yestitns, oapite punctnlato, fronte 

 transversim inipresso, vertice subcanaliculato ; tborace latitadine longi- 

 ore, angulis anticis valde rotundatis, basi tenniter marginata ntrinqne 

 obliqua ad medium rotundata, disco longHndinaliter, prawsipue antioe, 

 late concavo ; antennis pedibusque ferrugineis. Long. -15. 

 One specimen, Kentucky; Mr. J. J'h. Wild. The punctures 

 of the elytra are line, and not arranged»in rows ; near the base 

 there is a slight longitudinal subsutural impression. The anterior 

 tibiae are gradually dilated, and the external apical angle is acut< , 

 The form is rather broader and less convex than in th<_' other two 

 species.

It is with regret that I increase the very large number of genera 

 recognized in the family Tenebrionidse, bat the structural differ- 

 ences here detailed are such as to prevent the ref< rence of the 



species to any of the described genera. 



This genus, while showing a strong affinity with Uloma and 

 March, 1866.
