ACANTHOLOPHUS.

race spinis acutis 4-seriatim armato; elytris ad apicem mucronatis, seriatim

This species differs from most of its congeners in the shape of the crests over 
its eyes. These rise from the surface in the form of a single stem which branches 
into two spines, the hinder and larger one curved hindward, the anterior one 
appearing to branch off" from it and being curved forward and upward ; the whole 
crest somewhat resembles a deer’s antler. The median series of spines on the 
prothorax each consist of six spines ; the lateral series each consist of a large bifid 
spine near the front and a small bifid one behind it (both directed outward). The 
whole surface of the elytra is occupied by rows of small shining granules, inter¬ 
spersed with spines of diverse size as described above, the spines on the hinder part 
(none of them, however, continuing to the apex) of the second, third, and fifth 
rows of granules, and those at the base of the seventh series being the largest. 
Those near the base of the fifth series are very small (not much larger than the 
ordinary granules), and the two or three granules next after the basal 2 spines of 
the seventh series might almost be called small spines, being distinctly larger and 
more pointed than the ordinary granules. In Sir W. Macleay’s classification of 
the Acantholophi (Tr.E.S. N.S.W., Vol. I.) this species would fall, I think, in the 
first division of Section 2 (distinguished by elytra with three rows of tubercles, 
the external one containing less than four tubercles or spines). The peculiar form 
of the crest over the eye distinguishes this from the others of that division.
