 Bronze green with the base and sides of the prothorax, the elytra, 

 the under side and legs testaceous with a slight greenish tinge ; head 

 plicate in the anterior part, sub-punctate on the vertex, clypeal 

 carina situated a little nearer the apical part than the median, 

 well defined, and long in both sexes, frontal carina interrupted 

 in the centre, with each section curved, immediately behind the 

 interruption there is a distinct tubercle, the vertical carina is hardly 

 raised, and the gense are nearly straight, but not sharp at apex ; 

 prothorax convex, a little ampliate laterally in the middle, very 

 distinctly marginate all round, covered with moderately closely set 

 punctures and having only a faint trace of a raised, smooth, longi- 

 tudinal line in the middle, basal impressions deep, parallel ; scutellum 

 long for this genus, well defined ; elytra elongate, somewhat plane, 

 very deeply and broadly sinuate laterally at a short distance from 

 the median part, and slightly wider behind than at the base, they 

 are geminato-striate, the suture is raised, the intervals are also 

 raised near the base, and the sides from the carinate outer interval 

 to the fifth stria are very broadly impressed, these intervals are 

 faintly and loosely aciculate, and glabrous ; pygidium nearly im- 

 punctate ; pectus closely and densely granular ; metathorax very 

 closely punctured. 



Male : Clypeus moderately long, emarginate at tip, edges slightly 

 recurved ; anterior femora with a small spine on the upper margin 

 a little beyond the median part in the direction of the knee, and a 

 strong sub-vertical, curved tooth on the lower margin a little nearer 

 to the knee, anterior tibiae long, slightly bi-sinuate inwardly, curved 

 at tip, with the mucro also incurved but directed downwards, quadri- 

 dentate outwardly with the teeth widely separated, long and slender, 

 underneath the carina thickens at middle and bears there four or 

 five very distinct teeth (fig. 11) ; intermediate femora without tooth 

 but with the lower carina moderately deeply emarginate near the 

 knee ; trochanters of the posterior femora distinctly dentate, inferior 

 margin of the latter with two sharp teeth connected at base and the 

 outer of which is twice as long as the inner and curves slightly 

 inwards ; intermediate tibiae normal, posterior ones slender and 

 slightly curved at the base. 



Female : Clypeus elongate, sub-aculeate, not emarginate at tip.
