This species is much more delicately formed than the preceding 

 and differs in several particulars. The thorax is more quadrate, 

 not so wide in front, nor so much narrowed at the base, but 

 the hinder angles are more broadly rounded; the elytra are less 

 ovate, the shoulders not so much narrowed but broader and more 

 prominent, the sides less rounded in the middle, but straighter 

 and the apex broader, they are also much more delicately striated ; 

 and the entire surface of the insect, including the antennae, palpi 

 and legs, is uniformly black. Length 3 lines. 



The only locality in which I have found the insect is Bridge 

 Wood, near Tunbridge Wells. "Dalmeney Park and near

This insect is smaller and narrower than micans, and like the 

 preceding species in colour except that it has a greenish tinge on 

 the elytra. The head is narrower than in micans, the frontal
