Dolichopodidae. 365 



third; hind femora with a preapical bristle; hind tibiæ with two 

 dorsal rows, and about two ventral bristles; hind metatarsus a little 

 shorter than the second joint. Wings somewhat blackish tinged ; veins 

 black, the convexity on the last part of the discai vein slightly darkened ; 

 posterior cross-vein about in the middle, the part of the discai vein 

 from the small to the posterior cross-vein shorter than the second 

 part. Squamulæ yellow, with a brown or black fringe. Halteres 

 yellow. 



Female. Epistoma^very "slightly broader than in the male, somewhat 

 greyish above. Antennæ as in the male. Legs simple; front tibiæ 

 with a dorsal and a postero-ventral bristle, middle tibiæ with three 

 antero-dorsal, one postero-dorsal, and two ventral bristles. 



Length 2,2 — 2,5 mm. 



The female of this species resembles very much that of curvipes, 

 but according to my specimens it is distinguished from it by the yellow 

 front coxæ, which have more bristles ; also the first part of the discai 

 vein is shorter than the second, but this character is scarcely quite 

 valid ; on the other hånd the hind metatarsus seems to be not so much 

 shorter than the second joint as in curvipes. The female is also 

 difficult to distinguish from the female of the foUowing species. 



C. loripes is very rare in Denmark, I know only five specimens, 

 one from earlier time, probably taken in the vicinity of Copenhagen, 

 the others from Jutland at Struer and Gjerlev near Randers Fjord 

 (H. J. Hansen), and on Bornholm at Hammeren and Almindingen (the 

 author). The dates are in July and August. 



Geographical distribution: — Northern and middle Europe down 

 into France; towards the north to northern Sweden, and in Finland. 

 As Verrall notes (Entom. Month. Mag. XVI, 1905, 194) the species is 

 common in England, but it seems to be very rare on the Gontinent.

 reflexes, and a faint, greenish stripe in the middle; it is distinctly 

 brown pruinose, dull, only a little shining in the middle. Scutellum
