Wings a little brownish tinged; veins black or brownish black, costa with a somewhat large swelling, which is elongated, but shorter than in acuticoniis; discal vein with a slight, obtuse bend; axillary lobe small, anal vein directed. Fig. 39. Antenna of D. longicornis 9, from the inside. X 65. forwards. Squamulae whitish yellow, with a yellow fringe. Halteres pale yellow. Female. Epistoma broader than in the male, and a little more greyish. Antennae shorter, with the third joint considerably shorter, but distinctly attenuated towards the apex and pointed. Coxae more black-haired than in the male. Wings without costal swelling. The squamulae may have the fringe quite yellow, but there are generally more or less numerous black hairs, until the fringe is quite black. Length 3,5—4,3 mm. £>. longicornis is a common species in Denmark; Copenhagen in gardens, Lerseen, Amager, Vester Faelled, Damhusmosen, Charlotten- lund, Ordrup Mose, Ermelund, Fure So, Hillerod, Rorvig, Tisvilde, Sor0, Faxe Ladeplads;
