Male black, glossy, hairy beneath. Clypeus punctured more 
thickly towards the anterior margin where it curves upward, from 
the posterior part of the head arise 2 long curved spreading horns, 
the internal edges of which unite at the base and form a transverse 
line. (fig. 7.) Thorax sometimes tinged with rosy and green 
colours, thinly punctured, smooth before, where it is depressed in 
the centre, with 2 other depressed lateral lines appearing like the 
impression of the horns upon the head. Elytra with seven punc- 
tured striae on each, besides the margin ; slightly pubescent towards 
their apex in perfect specimens. Legs hairy. Tarsi and base of 
antennae ferruginous.— Female similar to the male excepting the 
head, which has no horns but a transverse elevated line behind 
the eyes where the horns arise in the male, and another transverse 
line just before the centre, (fig. 8.)
