Archive image from page 394 of Diptera Danica genera and species Diptera Danica: genera and species of flies hitherto found in Denmark dipteradanicage01lund Year: 1907 Empididae. 43 closing cross-veins perpendicular lo, not parallel with the margin: at the hind-margin, on each side of the lower corner of the discal cell (in the third and fifth posterior cell) there is a more or less faint, greyish patch, sometimes very slightly visible. Length —5 mm. Fig. Wing of Eh. spism-ostris Q. This species cannot be confused with nigripes; besides the size, the design of thorax and the clear wings, it is distinguished in the male by the thickened front metatarsi and the curiously haired middle metatarsi, as well as by many other differences in the pilosity of the legs, and in the female by the shape of the discal cell. Rh. spissirostris seems not to be common here: it occurs near water; Amager Fselled, Hillered, Boserup near Roskilde and on Falster at Resle. It is a spring species, my dates are jh— e; on the latter date I took it on Amager Faelled flying low over a water pool to- gether with the following species. Zetterstedt notes (VIII. 3031) as communicated by Steeger „Occurrit . . . tantum in litore maris', but this is not correct as the localities Hillerod and Boserup show. Geographical distribution:— Northern and middle Europe; its southern limit lies in Austria; towards the north to middle Sweden, and in Finland. 4. Rh. dissimilis Zett. 1849. Zett. Dipt. Scand. VIII. 3031, 2—3. — 1903. Kat. palaarkt. Dipt. II, 224. This species is very similar to spissirostris, and I shall therefore only describe it comparatively. Male. Somewhat larger ihoxi spissirostris \ frons somewhat broader. Thorax much darker grey and shining, the two stripes hence much less distinct, especially outwards as the sides of the disc are rather dark; the stripes are broader than in spissirostris. The dorsocentral and acrostichal bristles slightly longer; all thoracic bristles b
