54 Orper—COLEOPTERA. Section—PENTAMERA. 
posterior angles are obtuse, and rather rounded at their tips. The base of the scutellum is thickly covered with 
minute punctures, each bearing a minute luteous seta. The elytra are much broader, with the suture and two 
cost on each moderately elevated, slightly punctured, the punctures emitting luteous sete, and the inter- 
vening spaces marked with only a few longitudinally oblique scratches. The pygidium is angulated down 
the middle. The three teeth of the anterior tibie are not so strongly developed as in the other specimens- 
The abdomen beneath is black and glossy, with the transverse impression between the fourth and fifth seg- 
ments but slightly defined.

The head is entire, and rounded in front, with the margin slightly reflexed, and produced into two short 
conical points. On the crown of the head isa slight central raised line, behind which are two small raised 
tubercles (fig. 2a, head seen sideways) ; the sides of the head are marked with fine aciculated lines. The pro- 
thorax is nearly circular, black, and velvety. The elytra are polished on the dise, with longitudinal rows of fine 
punctures. The fore legs are robust; the tibiz rather bent outwards, with two teeth on the outside, and a third 
small rudimental one near the middle ; the ungues are very minute and triangular (fig. 2 e). The maxille have the 
mando produced at its inner angle into a flattened spine, which is obliquely truncate, and slightly bifid (fig. 2c).
