Diptera. 142 Orthorrhapha brach\cera. 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, somewhat short hairs, and on the inside fine, paler hairs, which are curved inwards. Legs yellow, front coxae whitish pruinose anteriorly, posterior coxas grey with yellow apex; anterior tarsi with the apex of metatarsus and the four following joints black, middle metatarsus often more or less darkened to quite black; hind tibige slightly darkened at the apex and hind tarsi black. The middle tibiae are somewhat long and thin, longer than the femora. The legs have short, black hairs, front coxae 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 tibiae with bristles above and one or two postero-ventral bristles; middle tibiae with four to five antero-dorsal bristles (one of them somewhat dorsal), two postero-dorsal, and with one ventral bristle below the middle; hind tibiae 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; discal vein with a some- what small, obtuse bend; axillary lobe large, anal vein going a little do^vnwards. Squamulae yellow with a black fringe. Halteres Fig. 44. Antenna of D. simplex 9, from the inside. X 65. Female. Epistoma broad, yellowish grey. Antennae slightly shorter than in the male. Front coxae more black-haired; for the rest similar to the male. Length 4—4,5 mm. This species may be known from notabilis, caligahis and lineato- cornis, besides by other characters, by the basal joints of the antennae being quite yellow, or at all eve
