The place of this species is near A. anreolus. The forehead is 



smooth and almost flat, with a sharp spine pointing backwards 



on each side between the eyes. The thorax is longer than broad, 



and is furnished with two parallel rows of six short acute 



tubercles on the back, and on the sides with a sharp spine and a 



small tubercle in front of it. The elytra are scarcely broader 



than the thoi'ax, coarsely punctured, and armed with two rows of 



strong spines. The first row or that nearest the suture consists 



of six spines, the apical one being the largest, the second row 



contains four. Outside the second row and immediately behind 



the shoulder there are two strong spines with a small tubercle in 



front of them. The apex of the elytra is slightly dehiscent. 



Both the thorax and elytra have a dorsal and a lateral vitta of 



white scales, and the latter have in addition an interrupted white 



vitta about the course of the second row of spines, and a number 



of white spots near the side. The medial or sutural vitta does 



not extend to the apex.
