the sides with an acute tubercle. The scutellum sub-trans- 

 verse, rounded behind. 



The elytra straight at the base between the shoulders 

 which are prominent and truncate ; they taper towards 

 and are conjointly rounded at the apex; they are covered 

 with deep punctures which are more or less placed in lon- 

 gitudinal series but disappear towards the end which is 

 opaque in consequence of a dense rugose sculpture; a 

 similar sculpture, though finer and less dense, is present 

 on the intervals between the punctures ; on the scutellar 

 region and on the shoulders rather large glossy granules 

 may be observed. 



The legs are nitid, sparsely punctate. The apical ventral 

 segment is short and transverse, broadly rounded behind, 

 gently emarginate in the middle, and fringed with rather 

 long black hairs.

 elytra are described as »dark steel-blue spotted with ful-
