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.
