Archive image from page 402 of Diptera Danica genera and species Diptera Danica: genera and species of flies hitherto found in Denmark dipteradanicage01lund Year: 1907 Empididae. 5] Female. Frons broad, grey. Abdomen grey, haired about as in tlie male, the hairs somewhat shorter. Legs dark brown, knees nar- rowly pale yellow, the hind tibiae and tarsi normal both in shape and colour; the legs are haired chiefly as in the male, but the hind femora have no bristles and are ciliated above and below, and like- wise the hind tibipe. Wings broad, almost half as broad as long, strongly brown fumigated. Length 4,5—5,5 mm. This species is at once recognised by the curiously shaped hind legs and the genitalia in the male, and by the dilated wings in the female, and by these characters it stands a little apart. Bh. vesiculosa is very rare here; I know only two specimens, one taken in Ordrup Mose many years ago (Jacobsen) and one in Jutland at Allerup near Esbjerg on /e 1909 (Esben Petersen). Geographical distribution: — Northern Europe, towards the north to northern Scandinavia, and in Finland; its southern limit lies in Denmark. It seems on the whole to be a somewhat rare species and is probably a spring species; Zetterstedt records it from /s—;t, and he has taken it on Salix. Remarks: I think it highly probable that this species is identical with Bh. atripennis Zett. as suggested by Frey (Act. Soc. pro Faun, et Flor. Fenn. 31, No. 9, 1909, 20); the differences are only such (colour of legs and wings) as may generally occur in species of Bhani- phomyia. 8. Rh. conformis Kow. 1867. Kowaiz, Verb. zool. hot. Gesell.
