I have seen only a single male. It is evidently allied to 

 and not unlike D. delaunayi, Fleut., but the elytral pattern 

 is more complicated, consisting of elongate scales or setae of 

 three different colours, brown, yellow, and white, in addition 

 to which those clothing the head and the front and side 

 margins of the pronotum are of a much richer yellow hue 

 and the disc of the pronotum, except a small triangular 

 white mark in front of the scutellum, is nearly black. The 

 scutellum is white, as well as the posterior half of the elytral 

 suture, dilating at the anterior end into an irregular trans- 

 verse median patch. The general surface of the elytra is 

 chocolate-brown, but the front and hind margins are buff- 

 coloured and are connected upon the outer half by longi- 

 tudinal streaks of the same colour, which become confused 

 in the middle. Just before the end of the elytral suture 

 there is a rather long tut't of golden hairs. The pygidium 

 is clothed with rather close-lying buff-coloured seta? and the 

 legs and lower surface bear long coarse hairs of the same 

 colour.
