the lateral line of the clypeus, head very distinctly granular ; 

 prothorax marginate all round, convex, very slightly impressed 

 longitudinally in the centre, and covered with small tubercles set 

 very closely, especially in the centre ; elytra attenuate laterally from 

 base to apex, distinctly striate, and with the intervals covered with 

 three or four more or less regular series of very closely set small, 

 briefly setigerous tubercles ; pygidium closely and finely granulose, 

 clothed with dense and long white hairs ; median part of prosternum 

 broadly smooth; the three penultimate joints of posterior tarsi short, 

 gradually decreasing, last one a little narrower than the preceding 

 one. 



Male : Clypeus elongate, a little rounded laterally from the 

 auriculate genge to the apex which is very suddenly recurved at 

 middle and bluntly triangular, the vertex is produced into a long, 

 laminiform, triangular process, very slightly cleft and bifid at tip, 

 the bifid tip not divaricating; prothorax more or less deeply 

 excavate, according to the length and width of the cephalic 

 laminate horn. 



Female : Gense projecting as in the male, but in a lesser degree, 

 clypeus shorter, and deeply emarginate at tip, edge of vertex dis- 

 tinctly carinate, the carina sinuate and incised in the centre, 

 between the frontal carina and the vertex there is another very 

 well defined carina, more raised than the frontal one, shorter and 

 strongly arcuate. This last character is met with in this species 

 only. 



Length 11-12 mm. ; width 7-7J mm.

Bronze green, turning to cyaneous on the upper side and 

 occasionally to coppery on the prothorax, briefly pubescent ; under 

 side nearly black ; head very coarsely punctured in the anterior 

 part and closely granulose on the genae and the posterior part, 

 gense projecting considerably in the shape of an auriculate process ; 

 prothorax convex, marginate all round, very closely and deeply 

 scabroso-punctate in the centre of the basal part, the punctures 

 replaced by small granules laterally and in front ; elytra convex, 

 moderately attenuate laterally from base to apex, deeply striate,
