Dolichopodidae. 73 



angularly; axillary lobe rather well developed, anal vein stretching 

 somewhat forwards. Squamulæ yellow, with a blackish fringe. Halteres 

 yellow. 



Female. Epistoma broader than in the male, grey. Antennæ a 

 little shorter, the third joint short, broader than long. Front tarsi 

 simple, but considerably longer than the tibiæ. Wings without costal 

 swelling. 



Length 4,7 — 5 mm. 



D. Falleni is rare in Denmark, we have only two specimens, a 

 male and a female, taken by Stæger at Lersøen many years ago ; as 

 however Schiner says, that he has had specimens from Stæger of this 

 species, there must have been more specimens; to be sure Stæger 

 says 1. c. that the species was common, but he mixed it together with 

 the foUowing. 



Geographical distribution : — Northern and middle Europe down 

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

 The species seems to be rather rare.
