ill both sexes in the middle, but more widely though not deeply in the 

 male, edges curved and greenish, genao projecting, a median trans- 

 verse clypeal carina of about half the width of the clypeus in l)oth 

 sexes, straight in the female, very slightly curved in the male, the 

 clypeal carina has two curves and a tubercle in the centre, and is 

 connected laterally with the carina on the vertex which is as much 

 raised as the frontal one, and is also slightly sinuate, it is closely 

 punctured in the anterior part, and scabi'ose on the vertex ; antenna? 

 flavescent ; prothorax dehiscent in the anterior part, in the male, 

 declivous in the female, not convex on the upper part, ampliated 

 lateralh' in front, and equally attenuated from the median part 

 towards the base in both sexes, broadly but not deeply impressed 

 longitudinally in the middle, generally more deeply in the male than 

 in the female, and covered, except on the sides, which are smooth, 

 with irregular, interrupted raised greenish hnes forming irregular 

 intervals tilled with minute, not closely set granules ; the two basal 

 impressions are deep and straight ; scutellum very sharp ; elytra 

 deeply sinuate laterally, nearly plane but with the suture slightly, 

 raised, finely striate, wdth the stria? geminate, intervals raised, 

 fifth highly carinate ; bearing each a series of spaced, shining green 

 tubercles, and having on each side a row of very short, fine, but rigid 

 flavescent hairs which are longer in the apical region ; pygidium 

 vertical, slightly rounded at apex, a little convex in the middle and 

 sub-punctate ; under side moderately hairy and rugose, metasternum 

 aculeate at tip. 



Male : Tubercle of the frontal carina very small ; anterior femora 

 with a sharp horizontal spine at the apex of the upper carina, 

 anterior tibicC curved inwardly and with the mucro long and curving 

 moderately inwardly, quadri-dentate outwardly, and bearing at 

 middle an inner horizontal, very distinct spine, and a smaller vertical 

 one next to it ; the intermediate femora bear no spine, but the inter- 

 mediate tibia} are broadly and deeply scooped out outwardly between 

 the first outer spine and the two apical ones ; posterior femora with 

 a thick, bluntly toothed carina on the upper edge, posterior tibige- 

 normal; prosternum with a broadly furcate, sub-vertical process 

 (fig. 16), which is, however, sometimes rudimentary. 



Female : Frontal carina with a very distinct conical horn in the 

 middle, prosternum carinate and sub-aculeate ; anterior legs normal, 

 intermediate tibia? also hollow^ed outwardly, but not as deeply as in 

 the male. 



Length 13-15 mm. ; width 7^8 mm.
