Wings hyaline; veins blackish to brown; the ui)per branch of the discal vein abbreviated, the anal vein very faint, abbreviated. Stigma distinct, brownish. Halteres blackish. Female.

The posterior legs compressed, strongly pennate on both sides, the scaly hairs longest on the hind legs; on the ventral side of the middle tibiae there are scaly hairs only at the base and on the hind tibiae on the basal half part. The wings tinged with brown, most strongly towards the base. Length 2,8 to about 3,5 mm. Remarks: Loew says, that the front metatarsi are quite simple, and they may also be termed so, but in comparison with the middle metatarsi they are quite slightly thickened. E. vitripennis seems not to be rare in Denmark, but it has not been taken many times and only on few localities; Ruderhegn, Geel Skov (the author); in Jutland in Greisdalen at Vejle (the author), at Rye near Silkeborg, Frijsenborg near Aarhus and Hald near Viborg (H. J. Hansen). My dates are ^hâ^'^h. In 1907 and 1909 I took it in great numbers in Geel Skov on ^hâ^â ^;1; they were flying quite low on places with Galluna between spruce firs. According to the dates the species is an autumn species.
