brownish black, arista somewhat short-pubescent. Palpi yellow, not 

 broad, with well developed bristles. Thorax black, a little shining, 

 with brownish pubescence. Mesopleura with uniform bristles. Abdo-

 at the hind margins of the segments. Hypopygium small, with numer- 

 ous hairs, especially below on the sides; anal tube yellowish, of medium 

 size, somewhat high. Legs brownish, front legs more yellow; front

tapering evenly without any marked contrast between metatarsus 

 and second joint; hind femora somewhat broad, with sparse, long 

 hairs below the basal half ; bristles on hind tibiæ somewhat numerous, 

 but distinct and not just small, longest about the middle. Wings 

 brownish, veins brown, thin veins a little strong; costa rather short, 

 about 0,45 of the wing-length, costal divisions about as 14 — 5 — 4; 

 costal cilia moderately long; fourth vein evenly curved in the whole 

 length. Halteres brownish black. 



Female. Unknown. 



Length 1,7 mm. 



This species will easily be distinguished in the group where it 

 must be placed, by the short costa and the proportions of the costal 

 divisions, and the same characters, I think, will serve to distinguish the 

 female. 



A. intercostata is rare, only one specimen, a male, has been taken, 

 Hejls south of Kolding V? 1919 (the author). 



Geographical distribution: — Hitherto only known from Den- 

 mark.
