tibise and tarsal joints are ringed with black at the extremities; 

 the forehead is black : the pronotuui red, with a large black patch 

 on each side, or entirely red ; and the elytra black, with an anterior 

 and posterior red mark on each, or red, with the margins and a 

 median patch npon each black. 



The form is small and slender and the legs long. The head 

 is finely punctured, with the clypeus about as long as it is broad 

 and gently emarginate in front. The irroaotum is (coarsely punc- 

 tured, slightly grooved along the middle and subcircular in shape, 

 with the sides straight and convergent in front, and the front 

 angles sharp. The scuteUwn is very short, nearly semicircular 

 and slightly punctured. The elytra are coarsely punctate-striate and 

 the jjygidiiua is very sparsely punctured. The front tibire are bi- 

 dentate, and the aniennal club is long in both sexes, very long in 

 the male. 



The upper surface is entirely opaque in the male, but the pro- 

 notum, scutellum and elytra are shining in the female. The pygi- 

 dium of the male bears a large white patch on each side and the 

 greater part of the sternum and abdomen is also white. The 

 prothorax is rather more elongate in the same sex, the hind tarsi 

 are longer and the abdomen is strongly arched beneath.

 behind the scutellum, a transverse spot 

 before the middle of each and a minute 

 apical spot near the suture, a large patch 

 on each side of the pygidium (the two 

 connected at the base), and the greater 

 part of the lower surface and coxaj. 

 The whole upper surface is opaque and 

 the head, pronotum, pygidium and lower 

 surface are clothed with pale yellow 

 hairs.
