black hairs which are nearly absent on the hind coxæ. The short 

 pubescence on the legs is blackish to brownish, but the fringe on 

 the ventral side of the hind femora is whitish, that on the hind tibiæ 

 brownish white; as usual there are some long, thin hairs on the legs; 

 the strong spine-like bristles are black. Wings relatively short, shorter

than in the other species; they are blackish brown on the basal half, 

 yellowish at the apex; veins dark brown; the anal cell closed or very 

 narrowly open. Balteres yellow to ferrugineous. 



Feraale. This differs somewhat from the male; the eyes in the 

 living specimens are bluish green. The face is whitish or brassy 

 pruinose; the epistomal beard and the hairs on the palpi yellow, the 

 hairs on the occiput brown or blackish brown. Thorax with three 

 more or less distinct hairy stripes, uniting posteriorly and disappearing 

 in the yellowish pubescence of the thorax; præsutural and supraalar 

 bristles yellow; the hairy stripes on the pleura yellow. The pubescense 

 on the abdomen is blackish but the long hairs on the lirst segment 

 yellow. The hairs on the coxæ are greyish and the fringes on the 

 hind legs paler than in the male; the strong bristles on the legs are 

 brownish to yellow. The wings are relatively a little longer than in 

 the male, they are paler, of a yellowish colour, somewhat brownish 

 at the base especially towards the anterior margin. — Varieties of the 

 female with paler legs I have not seen from Denmark. 



Length 9 — 11 mm. 



This species is easily distinguished by its dark legs and the dark, 

 in the male rather short wings; also the somewhat strong legs are 

 characteristic. 



D. atricapilla is rather common in Denmark; it occurs in the 

 herbage and high grass in fens, meadows and fieids, sometimes in 

 great numbers; Damhusmosen, Ordrup Mose, Ermelund, Dyrehaven, 

 Hillerød, the small wood Tyvekrogen, Tisvilde, Boserup near Roskilde 

 and at Skelskør; on Funen at Faaborg and at Lundeborg on the 

 eastern coast; in Jutland at Vejle and Silkeborg. My dates are ^''/s — 2*^/7. 



Geographical distribution: — The whole of Europe; towards the 

 north to southern Scandinavia where its northern limit seems to lie.
