Diptera. 158 Orthorrhapha brachycera. have a slight knob below near the base; front metatarsi about as long as the four following joints; hind tibise suddenly thickened at the end and here densely haired on the postero-dorsal side, hind me- tatarsi slightly thickened towards the base, almost as long as the second joint; it has a small, recurved spine at the extreme base on the postero-ventral side; coxae and femora grey, the latter shining some- what greenish olive, with the apex yellow, broadly on the anterior femora, but only slightly on the hind femora; anterior tibiae yellow with about the apical third blackish grey, hind tibiae dark yellow with base and apex black; anterior tarsi black with the base of metatarsus yellow, hind tarsi black; the front tarsi have the four last joints compressed and slightly dilated, a little hairy at the upper margin, the hairs on the last joint white. The legs have short, black hairs, the front coxae some bristly hairs above anteriorly; the femora have slightly longer hairs below; posterior femora with about four to five preapical bristles; front tibiae with bristles above and on the postero- ventral side, posterior tibiae with two dorsal and one ventral row of bristles. Wings hyaline or almost so; veins black; costa strongly thick-. Fig. 48. Wing of T. notatus d. ened on a streak between the base and the apex of the subcostal vein; discal vein with a slight bend lying much nearer the posterior cross-vein than the apex of the discal vein; the latter coverging to- wards the cubital vein, the first posterior cell narrowly open; posterior cross-vein straight or almost straight; there is a slight blackish spot on the bend of the discal vein and a similar seam on the posterior cross-vein. Squamulae pale yellow, with a black fringe. Halteres yellow, the peduncle darker. Female. Antennae slightly shorter than in the male. Epistoma a little broader upwards, pale grey
