the clypeus and the frontal part are hardly punctured, Init the genai 

 are distinctly granidate ; prothorax convex, ampliated laterally, 

 marginate all round, covered in the anterior part with scabrose 

 punctures which are not closely set and disappear in the posterior 

 part, median part of the base briefly aculeate ; elytra ampliate, 

 ovate, striate, striae punctulate but not distinctly geminate, intervals 

 plane, hardly punctulate, except the two outer ones, second interval 

 broader than the third ; pygidium with only a few widely scattered, 

 very shallow punctures ; metasternum and legs with only a few 

 punctures ; the former has a very faint longitudinal impressed 

 line. 



Male : Apical part of clypeus sub-truncate, emarginate at tip ; 

 head with two upright, slightly incurving horns between the eyes ; 

 prothorax declivous at apex, impressed on each side, and having in 

 the centre two very short tub^ercles divided by a narrow longitudinal 

 impression ; anterior tibiae very long, sub-arcuate, and with the 

 inner angle produced into a diagonal process longer than the apical 

 spur. 



Female : Clypeus more rounded laterally than in the male, and 

 more deeply emarginate at tip, frontal carina more developed than 

 in the male, instead of two parallel horns, there is a pre-basal 

 laminate carina ; the prothorax has also a moderately deep lateral 

 impression on eacli side of the anterior part, and the two median 

 tubercles are much more divergent, sharper, and overhang the de- 

 clivity a little ; the anterior tibiae are normal, and there is no inner 

 projection, nor spinose angle. 



Length 10h-V2h mm. ; 6-7^ mm. 



I have seen occasionally examples in which the discoidal part of 

 the prothorax has a slight violaceous tinge, and the median, dorsal 

 part of the elytra is also darker, somewhat bronze in colour, with 

 the base and sides fiavous.
