Black, head and prothorax opaque, elytra shining ; head trans- 

 versely plicate, clypeus acuminate, briefly bi-dentate laterally, 

 emarginate at the apex where the margin is a little reflexed ; 

 prothorax retuse, deeply scrobiculate all over ; elytra narrowly and 

 moderately deeply striate, intervals faintly and sparingly aciculate ; 

 pygidium covered with broad but shallow punctures ; metasternum 

 with a deep and broad basal impression, and without any longitudinal 

 impressed line. 



Male : Genae narrow, oblique, outer part of the base very sharply 

 triangular, angle of the suture distinctly dentate, head with a 

 median, sub-compressed horn, truncate, more or less emarginate at 

 tip, and curving slightly backwards ; in all the examples that I have 

 seen this horn is as high as the level of the median thoracic one ; 

 prothorax sub- vertical in front, very deeply but not broadly excavate 

 laterally and with the median part armed with three horizontal 

 horns extending further than the apical margin of the thorax, the 

 two lateral horns are aculeate at tip, but the median one curves very 

 slightly downward and is truncate and slightly emarginate at tip ; 

 second, third, fourth, and fifth intervals of elytra, and occasionally 

 the first also, with a sharp, elongate basal tubercle. 



Female : Genae a little oblique laterally and with the base angular 

 but not dentate, clypeus as in the male ; vertex with a highly raised 

 transverse post-median carina, slightly dentate on each side ; 

 prothorax retuse, strongly carinate at the top of the declivity, the 

 carina being strongly bi- sinuate. 



Length 34-36 mm. ; width 20-21 mm.
