which might, without examination, be considered as belonging to 

 Hoplocephala. 



HYPOPfflLOEIJS FABR. 



JOS. H. cavus. Elongatus cylindricus, piceus nitidus, haud dense 

 punctatus, pilis longis helvis parce vestitus, capite punctulato, fronte 

 transversim impresso, vertice subcanaliculato ; thorace latitudine longi- 

 ore, angulis anticis valde rotundatis, basi tenuiter marginata utrinque 

 obliqua ad medium rotundata, disco longitudinaliter, prsecipue antice, 

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



One specimen, Kentucky ; Mr. J. Ph. Wild. The punctures 

 of the elytra are fine, 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 acute. 

 The form is rather broader and less convex than in the other two 

 species.

 ultra oculos haud prominulis ; labrum transversum, apice late rotundatum, 

 meinbrana basali conspicua; antennae capite thoraceque haud breviores, 

 extrorsuni paruin incrassatse, articulo 3io praecedente sesqui longiore, 4-6

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

 recognized in the family Tenebrionidse, but the structural differ- 

 ences here detailed are such as to prevent the reference of the 

 species to any of the described genera. 



This genus, while showing a strong affinity with Uloma and 

 March, 1866.
