Deep metallic green, more or less coppery on the head and lower 

 surface and opaque above, with the antennae, legs and a broad line 

 extending from the shoulder to the apex of each elytron bright 

 orange ; decorated with pale yellow markings consisting of a 

 narrow longitudinal line at the middle of the pronotum, and a 

 marginal line and a minute median spot on each side, the scutellum, 

 a longitudinal line on each elytron near the suture, starting from 

 the base but not quite reaching the posterior edge, a basal, an 

 apical, and three lateral spots upon each, and large patches on each 

 side of the pygidium, sternum and abdomen. 



The body is moderately slender and the legs are very long, the 

 front tibia armed \\'ith two teeth at the extremity and slightly 

 serrated beyond them. The club of the antenna is shorter than 

 the footstalk in both sexes. The head is I'ugosely punctui-ed, and 

 the clypeus a little longer than it is broad and not very deeply 

 notched at the front margin. The jpronotum is strongly punctured, 

 lightly grooved along the middle and rather broader than it is long, 

 with the front angles acute, the hind angles very bluntly pro- 

 minent and the sides and base gently curved. The scutellum is 

 shortly triangular. The elytra are strongly punctate-striate, the 

 pygidium finely rugose, and the metasternum and abdomen punc- 

 tured and clothed with a short yellow pubescence.

 female, the prothorax is broader at the base and the abdomen is 

 strongly arched. The vertex of the head and the pronotum are 

 generally more opaque, and there are often additional pale mark-
