 finely punctate. Clypeus convex, the lateral angles prominent but 

 rounded, the front convex. Thorax transverse^ scarcely sinuate 

 behind, convex, smooth, rounded on each side but very little 

 sinuated at the anterior angles of the margins, those large, concave, 

 with a very small and nitid border ; the anterior angles about a 

 third of the length of the head. Elytra convex laterally, 

 depressed above, sub-parallel, rounded towards the apex, and a little 

 pointed terminally ; humeral regions scarcely prominent ; on each 

 elytron are numerous rather indistinctly raised costse, becoming 

 obliterated laterally and towards the apex ; the intervals furnished
