. have longish, black hairs above. Legs somewhat slender, black, al- most not pruinose; the knees yellowish; coxse grey pruinose. Front femora with fine hairs on the posterior side, and a few long hairs on the anterior side; middle femora with ^ bristles on the antero-dorsal side and fine hairs below; j | hind femora with longish hairs above and towards the apex below; front tibiae short-haired, and with a few bristles on the dorsal side; middle tibiae with short bristles below; hind tibiae short-haired, and with bristles on the dorsal and anterior side. Front tibiae slightly thickened towards the apex, metatarsi somewhat thicker, short-haired, somewhat shorter than the tibiae and as long as the four following joints; all tarsal joints longer than broad, only the fourth joint on the middle tarsi as broad as long. All hairs and bristles black or blackish. Wings hyaline. Veins black or dark brown; the upper branch of the cubital vein somewhat diverging. Stigma dark brown. Halteres yellow. Female. Similar to the male. Front metatarsi simple, half as long as tibiae, and a little shorter than the four following joints; all tarsal joints longer than broad, except the fourth joint on the middle tarsi; hind tibiae , somewhat compressed and distinctly curved in the middle, front leg. x 30. Length 3—4,2 mm. This species somewhat resembles the three preceding, but it is recognised at once by the dark occiput with a bluish grey triangle; it is also a little smaller. Remarks: I think it beyond doubt that Zetterstedt's quadrlvittata is the present species; his description agrees rather well, and he says: ''Specimina plura utriusque sexus ut frequens Daniae incola etiam a D. Staeger missa"; now all specimens in Staeger's collection labelled quadriviitata were carinthiaca. H. carinthiaca is a common species in Denmark; neighbourhood of Copenhagen, Ordrup Mose, Dyrehaven at Rode Bro, at Skelskor; on Faen0, and in Jutland in Vejle Nerreskov, Greisdalen and at Hors
