Vertex and front minutely granulose, the latter finely stri- 

 gose immediately above the encarpge ; encarpa separated from 

 the front by a transverse groove, contiguous, transverse; 

 carina strongly raised, linear ; anterior border of labrum 

 fulvous ; antenna? nearly three fourths the length of the body, 

 filiform. Thorax broader than long; the sides straight and 

 slightly diverging from the base to some distance beyond the 

 middle, thence rounded and converging to the apex, the an- 

 terior angle armed with an obtuse tubercle; hinder disk 

 rugose-punctate, impressed just in front of the base with a 

 short longitudinal groove ; scarcely in front of the middle 

 disk is a large, deeply impressed, semilunate sulcus, the surface 

 of which is deeply trifoveolate, its anterior border thickened, 

 the space immediately in front of the raised margin concave 

 and nearly free from punctures. Elytra broader than the 

 thorax, parallel, subelongate, convex, inflated below the
