Legs long, pale yellow; front coxae whitish anteriorly, posterior coxae grey, just at apex yel- low ; middle tarsi with the four last joints black, hind tibiai a little black at the apex, especially on the posterior side, and hind tarsi black; front tarsi long and thin, nearly twice as long as the tibiae, the three middle joints long, the third and fourth about equal in length, the last com- pressed, dilated, of ovate shape, it is black, white at the base, haired at the margin. The legs have short, black hairs, the front coxae white- haired with a few black hairs, and the hind femora with inconspicuous pale hairs beneath; posterior femora with one preapical bristle; front tibiae with bristles above and on the posterior side, middle tibiae with about five to six antero-dorsal (one of them dorsal), two to three postero-dorsal, and two (sometimes one) ventral bristles below the middle; hind tibiae with two dorsal rows, and with one ventral bristle. Fig. 23. Wing of D. discifer. towards the apex, besides with a ventral row of fine, small bristles; hind metatarsi with about four dorsal bristles, some anterior, and small bristles below, middle metatarsi with some small bristles below at the sides. Wings somewhat narrow, yellowish or slightly brownish tinged, most towards the anterior margin; veins black, costa with a very small and inconspicuous swelling; discal vein with a small bend which is almost not double, and hence the vein is convergent towards the cubital vein; axillary lobe large, anal vein short, only reaching half way towards the margin. Squamulae yellow, with a black fringe. Halteres pale yellow. Female. Epistoma broad, greyish. Antennae shorter than in the male, third joint short triangular. Front tarsi simple, not long; the middle tibiae may have seven antero-dorsal bristles, and there are al- ways two, or s
