Color ferruginous brown, shining; head, tip^ of armature, margins of prothorax and a spot near the outer margin of pro- thorax either dusky or black. Head: Clypeus trans- verse and feebly augulate at the sides, the front edge rising inerea-^iugly backward, until just before reaching the clypeal suture it ends in a well formed tubercle on either side; behind the sutural line on the ver- tex is a very prominent, stout, conical horn in front of the base of wh'ch the surface of the head is slightly coucave; three-fourths of the lower portion of the horn and the whole of the frontal area finely rugose. Antenufe: funicle shining, chestnut; club paler, not shining. Thorax: subtriangular. deepest longitudinally through the center; noticeably wider than the elytra at th-ir juncture, and rather wider th m their greatest breadth; seen from above the front margin appears truucate in the middle, then trends obliquely forward to the angles which are prominent; sides straight for a short distance, pos- terior angles strongly rounded; posterior margin much extended in the mid- dle with distinct siuaations toward the angles. The front area deeply con- cave, surmounted by four well formed tubercles; two occupying the center, bold and projecting over the concavity, two others, one on either side of the central two, situated near the anterior margin of the thorax at its exterior angles. The arda around the two anterior tubarcles very ragosely punctate; and transversely across the disc are large distinct punctures nowhere ex- tending to th^ posterior margin. A wall defined margin, reflexed at the sides, surrounds the whole. Elytra: very convex, obtusely rounded behind, having fourteen well defined and regularly punctured striae, the interstices of which are 11 ittene;! aud indistinctly wrinkled. The under side paler than the upper; dense fringe.? of light chestnut hair line the reflexed portion of the thorax and elytra, while the femora, tibia aud tarsal joints, as well as the lower side generally, are well supplied with rather long chestnut hair.
