Archive image from page 203 of Diptera Danica genera and species Diptera Danica: genera and species of flies hitherto found in Denmark dipteradanicage01lund Year: 1907 22 Orthorrhapha brachycera. black hairs which are nearly absent on the hind coxae. The short pubescence on the legs is blackish to brownish, but the fringe on the ventral side of the hind femora is whitish, that on the hind tibiae brownish white; as usual there are some long, thin hairs on the legs: the strong spine-like bristles are black. Wings relatively short, shorter Fig. 8. Wing of D. atrica'piUa. than in the other species; they are blackish brown on the basal half, yellowish at the apex; veins dark brown; the anal cell closed or very narrowly open. Halteres yellow to ferrugineous. Female. This differs somewhat from the male; the eyes in the living specimens are bluish green. The face is whitish or brassy pruinose; the epistomal beard and the hairs on the palpi yellow, the hairs on the occiput brown or blackish brown. Thorax with three more or less distinct hairy stripes, uniting posteriorly and disappearing in the yellowish pubescence of the thorax; praesutural and supraalar bristles yellow; the hairy stripes on the pleura yellow. The pubescense on the abdomen is blackish but the long hairs on the first segment yellow. The hairs on the coxae are greyish and the fringes on the hind legs paler than in the male: the strong bristles on the legs are brownish to yellow. The wdngs are relatively a little longer than in the male, they are paler, of a yellowish colour, somewhat brownish at the base especially towards the anterior margin. — Varieties of the female with paler legs 1 have not seen from Denmark. Length 9 — 11 mm. This species is easily distinguished by its dark legs and the dark, in the male rather short wings; also the somewhat strong legs are characteristic. D. atricapiUa is rather conmion in Denmark: it occurs in the herbage and high grass in fens, meadows and fields, sometimes
