Lucanide. 359 
The head is transverse, with the sides, including the 
lateral canthus of the eyes, nearly parallel; the hinder 
angles behind the eyes rounded; the canthus extends 
backwards half the length of the eyes, in front of each of 
which is a lateral depression. ‘The labrum is very short, 
transverse, broad, with the fore-margin moderately emar- 
ginate. The mentum is broad, with the lateral anterior 
angles rounded, the disc marked with shallow cicatricose 
punctures. The mandibles are sickle-shaped, twice the 
length of the head, with a large, nearly central, tooth 
arising on the upper edge, and slightly porrected. ‘The 
prothorax is transverse, with the front rather wider 
than the head, having the anterior angles slightly dilated 
and rounded, and the hind ones oblique; the disc is 
entirely even, without sulci or impressions, the whole, 
hke the head, being opaque, and, when seen with a strong 
lens, entirely covered with exceedingly minute granula- 
tions. The elytra are oblong, slightly wider in the 
middle, where they are equal in breadth to the middle 
of the prothorax; they also are opaque, except along 
the sides of the suture and about the scutellum, where 
they (as well as the scutellum itself) are polished; the 
humeral angles are elevated. The disc is destitute of 
coste or sulci. The fore legs have the tibiz rather 
narrow, and armed with about eight teeth on the outer 
margin. The four hind tibizw are also rather slender, 
with a spine on the middle of each on the outer edge.

This insect is about equal in size to the preceding, but 
the mandibles are shorter, and the polished elytra, marked 
with several very indistinct cost, distinguish it from 
that species. The head is transverse, narrower than the
