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 emargination of the head posteriorly are subacute in A. arcens ; in the other species they are distinctly rounded.
