elytron. The legs and lower surface are clothed with rather 

 thick greyish-yellow pubescence, through which the reddish 

 colour of the integument is visible. At the shoulders of the 

 elytra the scales change to narrow seta?, which also leave 

 exposed the red underlying surface. 



In the male the legs are extremely massive, the front tibia 

 is without the usual strong lateral tooth but tapers to a 

 point at the extremity, the middle tarsi are extremely short 

 and the hind tarsi moderately long, but less slender than in 

 D. ochracea. The abdomen is very strongly contracted 

 in this sex, the pygidium long, vertical, and densely clothed 

 with yellow scales. 



In the female the front tibia has a very small and incon- 

 spicuous lateral tooth, all the tarsi are moderately slender, 

 and the pygidium is broad and clothed with grey setse.

This evidently resembles the very insufficiently described 

 D. borneensis, Brenske, but it is smaller, and the pale border 

 of the pronotum is not confined, as in that species, to the 

 front and lateral margins. As in D. borneensis, the pro- 

 notum and elytra bear pale scattered scales standing out 

 from the rest, those upon the elytra being arranged in 

 longitudinal rows. The upper surface is closely clothed with 

 brown scales, replaced by white scales at the margins of the 

 pronotum and an incomplete median line, as well as upon 

 the scutellum and three longitudinal lines upon each elytron, 

 the first bordering the suture and abbreviated anteriorly.
