 ever, in all its other characters.

C. oblong-elongate, convex, pale fuscous or obscure fulvous ; suture 

 broadly piceous. Face excavated between the eyes ; armed in 

 the male wdth a flat slender horn, which, arising just above the 

 elypeus, curves upwards between the antennae ; its apex slightly- 

 dilated, truncate. Thorax transverse-quadrate ; sides rounded, 

 sinuate behind, narrowed in front, anterior angles obtuse, pos- 

 terior slightly produced, acute ; apical margin slightly produced ; 

 above convex, smooth and shining, disc impunctate, sides and 

 base coarsely punctured ; in front, connected with the anterior 

 margin are two small shallow foveoe. ScuteUum smooth. Elytra 

 broader than the thorax ; sides parallel, narrowly margined, obso- 

 letely bisinuate below the humeral angle ; apex regularly rounded ; 

 above convex, indistinctly flattened along the suture ; each elytron 

 with eleven rows of deep distinct pimctures, the first abbreviated, 

 striae (those near the sutiu-e excepted) sulcate, their interstices 

 raised, subcostate ; on the anterior half of the outer margin a 

 naiTow vitta, and a broader one on the suture, abbreviated towards 

 the apex, nigro-piceous. Beneath fuscous ; anterior pair of thighs
