. Diptera danica : genera and species of flies hitherto found in Denmark. Diptera -- Denmark. 142 Oi'thorrhapha brachycera. ventral, apical and outer half of the dorsal edge; at the end there are some teeth with black, curved hairs; the ventral margin has few, soniewhat short hairs, and on the inside fine, paler hairs, which are curved inwards. Legs yellow, front coxæ whitish pruinose anteriorly, posterior coxæ grey with yellow apex; anterior tarsi with the apex of nietatarsus and the four foUowing joints black, middle metatarsus often more or less darkened to quite black; hind tibiæ slightly darkened at the apex and hind tarsi black. The middle tibiæ are somewhat long and thin, longer than the femora. The legs have short, black hairs, front coxæ white-haired anteriorly on the outer part; hind femora with a little longer hairs above towards the base, and inconspicuously pale-haired below; posterior femora with one preapical bristle; front tibiæ with bristles above and one or two postero-ventral bristles; middle tibiæ v^^ith four to five antero-dorsal bristles (one of them somewhat dorsal), two postero-dorsal, and with one ventral bristle below the middle; hind tibiæ with two dorsal rows of bristles, one ventral bristle towards the apex, and a ventral row of small bristles; hind metatarsi with about two dorsal, one anterior, and with small ventral bristles. Wings a little greyish or yellowish tinged; veins black or blackish; discai vein with a some- what small, obtuse bend; axillary lobe large, anal vein going a little downwards. Squamulæ yellow with a black fringe. Halteres Fig. 44. Antenna of D. simplex 9, from the inside. X 65. Female. Epistoma broad, yellowish grey. Antennæ slightly shorter than in the male. Front coxæ more black-haired; for the rest similar to the male. Length 4—4,5 mm. This species may be known from notabilis, caligatus and lineato- cornis, besides by other characters, by the basal joints of the antennæ being quite yellow
