Z>. vulpixms, F. Oblong, unicolorous black, moderately shiny, 

 elytra clothed with sparing greyish pubescence; head 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- 

 tured, with apical sutural angles mucronate ; legs covered with brownish 

 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 

 two white longitudinal patches ; male with a bunch of brownish bristles

In hides, fui-s, natural history specimens, &c. ; very common in many localities, 

 especially in and about large towns ; London district, common ; Lowestoft;' Devon ; 

 Scarborough ; Wallasey ; Manchester ; Northumberland and Durham district ; 

 it has not yet been recorded from Scotland, but probably occurs in Edinburgh, 

 Glasgow, &c. 



D. Friscliii, 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. 

 L. 6-8| mm.
