The frontal lamina of the male is so deeply emarginate that its 
two ends stand up almost like horns when looked at from a 
certain point of view.

A. Tasmanie, Hope. Harold (Berl. Zeit., 1861, p. 94) rede- 
scribed this species very fully, and pointed out that A. Hovwi7itte is 
a variety of the same. He, however, says nothing about the 
sexual characters, having, I presume, only one sex (evidently the 
female) before him. The male differs by its very much wider 
prothorax, which to a casual glance appears considerably wider 
than the elytra, but is in reality just the same width as the 
widest part of the elytra; the prothorax of the male, moreover, 
is much less strongly punctulate than that of the female, and the 
anterior tibie are much narrower and more elongate with their 
external teeth, though not much shorter, yet evidently narrower 
so as to be more widely separated one from another. The pro- 
thorax of the female to a casual glance appears of the same width 
as the elytra, but measurement shows it considerably narrower 
than the widest part of the elytra.
