numerous and close in the middle. Tlie ante-ocular ridges are a 

 little more prominent. In the male the inner anterior claw is 

 quite simple. The genitalia of all these species are quite different 

 in the male.

This is almost of the same size and shape as A. piceum, F., but 

 a very little larger and more elongate. It is black and shining, 

 with "the legs and underside piceous. The head is closely rugose, 

 bituberculate in front and armed on the vertex with two tubercles 

 placed moderately far apart. The 'protliovax is very distinctly but 

 not closely punctured, the punctures being finer in the middle. 

 There is a faint impression just behind the middle of the front 

 margin and a slight elevation in front of it. The scutellum is 

 broad and unpunctured. The elytra have each a very deep, not 

 distinctly punctured sutural stria and four pairs of strongly punc- 

 tured striae, the first and seventh interstices being irregularly 

 punctured and the third and fifth having each an incomplete line 

 of punctures ; the outer and apical margins are strongly and 

 closely punctured. The propygidium is slightly produced and 

 bears a pair of fine and moderately broad files. The pyrjidium is 

 strongly but not closely punctured. 



The sexes are alike.

Black, reddish beneath, very smooth and shining, convex and 

 rather broadly oval, the elytra widening almost to the end. The 

 head is rugose, bidentate in front, and provided with two median 

 tubercles. The pronotum is coarsely and rather closely punctured, 

 except in the middle, where there is a slight anterior impression 

 and a minute elevation immediately in front of it ; the sides are 

 strongly curved and the hind angles completely rounded off. The 

 scutellum is smooth and the elytra are short and rather broad 

 posteriorly, deeply striated, with the striae coarsely punctured ; 

 the subsutural interval is broad and has a few punctures, and the 

 apical margins are irregularly punctured. The liropyii'idium is 

 produced, and the pjygidium finely punctured in the middle and 

 closely at the sides. The metasternum and abdomen are almost 

 smooth. 



The sexes are alike.
