dicular face is smooth and nitid and its height is about equal 

 to the thickness of one of the palpi. The species is nearest 

 (but not very near) to //, severus, Blackb., from which it 

 differs, utter alia, by the extremely fine basal edging of its 

 pronotum, by the very miich finer and closer puncturation 

 of its elytra (on which the punctures are much finer and 

 closer than those of the pronotum), and by the puncturation 

 also very much finer on the ventral segments.

 Easily distinguishable in the subgroup by the remark- 

 able sculpture of its frons, also oy its small size, etc. The 

 sexes seem to be scarcely distinguishable except by the basal 

 joint of the hind tarsi a trifle longer in comparison to the 

 next two joints in the sex which I take to be the male.
