Coleopt., Heft. ii. 1867, p. 53. 



Green, moderately shining, densely pubescent ; elytra flavous or 

 light chesnut-brown ; gense nearly straight, clypeus roughly plicate, 

 frontal part granulate ; prothorax covered with very closely set 

 granules, convex, ampliate laterally, marginate all round, basal part 

 rounded in the middle ; elytra a little ampliate laterally in the 

 anterior part and gradually attenuate towards the apex ; striae 

 shallow, geminate, distinctly punctured, intervals plane, filled with 

 deep, setigerous punctures, second interval not much broader at 

 middle than tlie third, humeral callus distinct ; pygidium very 

 closely punctured and covered with dense, silvery white hairs ; 

 metasternum closely punctured ; inner part of anterior tibiae not 

 spinose, apical spur long, nearly straight in both sexes. 



Male : Clypeus sub-diagonal laterally, obtuse at tip ; the frontal 

 carina is distinct, and between the frontal carina and the base there 

 is a long, compressed horn curving a little past the median part, and 

 some 3J to 3^ mm. in length ; prothorax very convex, moderately 

 declivous in the anterior part which is impressed in the middle, 

 this impression is very shallow, and is continued from the apex of 

 the declivity to the base as a narrow, longitudinal line. This 

 shallow median depression is not indicated in the figure 19. 



Female : Clypeus more regularly rounded, the frontal carina is 

 arcuate, and between this carina and the base there is a very 

 distinct transverse high lamina truncate at each end ; the prothorax 

 is more abruptly declivous in the anterior part, and bears at the 

 apex of the declivity a small triangular lobe, emarginate in the 

 middle, and higher than the plane of the dorsal part of the disk 

 (fig. 19a).
