rowing towards the apices which are truncate and have 

 each two spines, the sutural one longer and more acumi- 

 nate than the external one; the elytra are covered at the 

 base with glossy black granules, each of these followed by 

 a deeply impressed puncture, the granules and punctures 

 smaller and more scattered towards the middle, larger and 

 more densely set towards and on the shoulders; on the 

 middle the granules are replaced by punctures at some 

 distance beyond the scutellum, at the sides at one third 

 of the length of the elytra, and these punctures become 

 smaller and smaller towards the end of the elytra. 



Mesosternal process bluntly angular.

 from that genus.
