 elytra clothed with sparing greyish pubescence; bead thickly and rather 

 coarsely punctured, densely pubescent ; antennae red or pitchy-red ; 

 thorax rather long, considerably narrowed towards front, thickly and 

 rather strongly punctured, clothed with strong whitish-grey pubescence 

 at sides and usually in front, central portion almost bare ; scutellum 

 thickly covered with orange-yellow hairs ; elytra black, thickly punc-

 hairs ; under-side clothed with long and thick white pubescence with a 

 row of black spots at each side near margins, last segment black with

D. Frischii, Kug. Very closely allied to the preceding, but easily 

 distinguished by having the elytra simple at apex, and by the fact that 

 the white pubescence of the sides of thorax is interrupted at base so that 

 the thorax has a black spot at each hinder angle ; the dark central 

 space, moreover, on the last segment of the abdomen is terminal only, 

 and not produced as in D. vulpinus ; the male has the fourth seg- 

 ment of the abdomen furnished with a bunch of brownish bristles.
