fitting into deep notches formed between the scutellum and 

 elytra. Between the two projections is a rounded lobe, 

 and the excisions between this and the former are not sharp 

 but rounded. The prothorax is much narrower than the 

 elytra, but is relatively broad behind and narrow in front. 

 Both front and hind angles are sharp, especially in the male. 

 The scutellum is broad, almost transverse, extremely blunt 

 behind. The elytra are rather flat, with a prominence at 

 the shoulder but dilated behind it, separately rounded 

 at the extremity and. not covering the abdomen behind. 

 The latter is not long, and consists of six visible segments 

 ventral ly. The front coxae are very prominent vertically, 

 'the hind coxae produced and prominent laterally, the front 

 tibiae have two not very acute teeth and all the tarsi are 

 long, except the middle ones in the male. The claws are 

 long, stout, and symmetrical, not blunted at the tips, those 

 of the front feet cleft and the rest entire. The antennas 

 are slender in both sexes, joints 2 and 7 stout and all the 

 rest elongate. 



In the male the legs are much stouter than in the female, 

 the front tibia is narrower and the teeth much closer 

 together, the middle tarsus is very strongly contracted, its 

 2nd, 3rd, and 4th joints saucer-shaped, but each angularly 

 produced externally, the hind coxa is broader and more 

 exposed laterally, the hind femur thickened and a little 

 arched, the hind tibia produced into a broad angular plate 

 internally and without terminal spurs. The abdomen is not 

 arched, the pygidium is broad and the propygidium not 

 exposed. 



In the female the abdomen is very convex beneath, the 

 propygidium and. pygidium are exposed and the latter is 

 very oblique.
