Legs somewhat long, yellow; the front coxae at the base and the posterior coxae grey; the middle tarsi with apex of metatarsus and the four last joints black; hind tibiae black just at the apex and hind tarsi black; front tarsi long, but not twice as long as tibia, the fourth joint about half as long as the third, the last joint compressed, dilated, triangular and larger than in discifer, it is black, and hairy at the margin. The legs have short, black hairs; posterior femora with one preapical bristle; front tibiae with bristles above and one or two on the postero-ventral side; middle tibiae with about five antero-dorsal, two postero-dorsal, two antero-ventral or the upper ventral, and one postero-ventral bristle; hind tibiae with two dorsal. Fig. 24. Wing of D. confmus d". rows of bristles, and a ventral row of rather long bristles, the lower- most longest; middle metatarsi with one bristle above; hind metatarsi with three bristles above, some anterior, and small bristles below. Wings a little broad, slightly tinged; veins black or brownish black; discal vein with a large bend, approaching to be rectangular and the lower angle distinctly angular, often with a small veinlet, the upper angle more rounded; axillary lobe small, anal vein stretching some- what long forwards. Squamute yellow, with a black fringe. Halteres yellow. Female. Epistoma broader than in the male, but not specially broad. Antennae considerably smaller and shorter and the third joint shorter than in the male. Front tarsi simple. Wings not so broad, darker, brownish tinged. Length 4—5,7 mm. B. confusus is not rare in Denmark; Tisvilde, Rorvig, Vedbaek; in Jutlan
