There is a very close resemblance between A. arcens and A. 

 Burmeisteri ; the distinctions are, that in the former the head is 

 highly polished, perfectly smooth, entirely destitute of punctures 

 or sculpture ; in the latter the head is subopake and covered 

 with a very delicate reticulation ; the lateral angles of the emar- 

 gination of the head posteriorly are subacute in A. arcens; in the 

 other species they are distinctly rounded.
