This species is readily recognisable among those of the present 

 Group by the coarseness and riigulosity of its elytral sculpture. 

 The convex interstices of the punctures are of various sizes and 

 dispositions, but they are not of the isolated character that would 

 entitle them to be called verruca3.

This species is notable among its allies by the presence on the 

 elytra of feebly defined unpunctured spaces of an unusual shape. 

 When present these spaces are usually in the form of distinct 

 continuous vittee, but in the present insect they are somewhat 

 oblong and very indistinctly limited spaces so placed as to look 

 like detached pieces of vittse.
