long ; sides nearly parallel, obliquely converging towards the 
apex ; disk smooth, minutely punctured, transverse groove rather 
more deeply impressed on either side. Elytra broadly dilated 
posteriorly, convex, transversely excavated below the basilar 
space ; minutely punctured, lateral limb reflexed, more strongly 
punctured than the disk. 
Broader in both sexes than A. atripennis, Fabr., the lateral 
margin of the elytra broader and more strongly punctured.

mare ) nigro-piceo. Long. 3-4 lin.

Antennae slender, filiform. Thorax transverse ; sides obliquely 
diverging from the base to beyond the middle, thence converging 
towards the apex ; disk smooth, impressed on either side with a 
few minute punctures ; discoidal sulcation nearly straight. Elytra 
dilated posteriorly, convex, transversely excavated below the 
basilar space, very finely punctured. 
This species is smaller in size than either of the following two ; 
the deeply concave intermediate lobe of the anal segmentof the ab- 
domen in the male, together with the obtusely emarginate apex of 
the same segment in the female, will separate it from either. Many 
of the specimens that I have seen differ from the diagnosis given 
by Eabricius in not having the basal joint of the antenna; darker 
than the following ones ; in other respects they agree with the 
description given. I possess three specimens of the male ; in 
this sex the labrum is piceous, in the other one it is coucolorous 
with the upper face ; in some individuals the legs are stained 
with p ceous.
