 the horn and tbe whole of tbe frontal area finely rugose. Antennae: funicle 

 shining, chestnut; club paler, not shining. Thorax: subtriaugalar, deepest 

 longitudinally through the center; noticeably wider than tbe elytra at tbt-ir 

 juncture, and rather wider th m their greatest breadth; seen from above the 

 front margin appears truncate in the middle, then trends obliquel}' 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 sinaations toward tbe angles. The front area deeply con- 

 cave, surmounted by four well formed tubercles; two occapjang the center, 

 bold and projecting over tbe concavity, two others, one on either side of tbe 

 central two, situated near the anterior margin of tbe thorax at its exterior 

 angles. The arja around tbe two anterior tubsrcles very ragosely punctate; 

 and transversely across the disc are large distinct punctures nowhere ex- 

 tending to the posterior margin. A well defined margin, refiexed at the

 having fourteen well defined and regularly punctured striae, the interstices 

 of which are fl;\tten3d and indistinctly wrinkled. The under side paler than
