 sharp, triangular tooth ; anterior part of the prothorax excavate, but

Dark slightly leneous bronze, opaque on the upper side, 

 moderately shining underneath ; clypeus closely granular, frontal 

 carina moderately high ; prothorax ampliated laterally but with 

 the median part somewhat straight, marginate all round, convex, 

 and with the median part of the base slightly aculeate, it is closely 

 granulose, and briefly pubescent ; elytra narrower than the prothorax 

 at its widest part, not ampliated beyond the shoulder, and attenuate 

 from there towards the apex, not quite plane, shorter than the 

 prothorax, distinctly geminato-striate, intei'vals plane, filled with 

 closely set, briefly setigerous minute granules, second interval much 

 broader than the third which is of the same width as the fourth, 

 humeral callus distinct ; pygidium moderately closely punctured ; 

 nietasternum scabrose in the centre in front, and punctulate behind ; 

 apical spur of anterior tibiae curved inwards at apex in both sexes, 

 and with the inner angle not spinose. 



Male : Gen® and clypeus distinctly recurved, the latter semi- 

 circular, frontal carina very small, vertex produced into a high carina 

 emitting on each side a curved, recumbent compressed horn reaching 

 to a short distance from the base of the prothorax, truncate at apex, 

 in the centre there is a robust, compressed horn deeply emarginate 

 at tip and directed backwards towards the very deep, orbicular 

 cavity of the anterior part of the prothorax which is surmounted 

 by a sub-vertical, long, compressed horn, bluntly bifid at tip, in the 

 small development the shape of the carina and the horns on the 

 vertex is exactly similar to that of the small development of
