Face distinctly arched, only slightly greyish just at the eye- margins; epistomal heard varying in colour from black with whitish ends of the hairs to quite whitish. Proboscis and palpi black. Frons and vertex black with brownish hairs. Occiput grey with whitish hairs. Antennae black. Thorax black, somewhat shining, coarsely punctate; two narrow median lines glabrous. The disc clothed with long hairs which are black or brownish in front, paler to whitish backwards. Scutellum with white hairs. Pleura black, somewhat greyish pruinose; they are more distinctly hairy on a spot below the humerus, on the hind part of the mesopleura, on the pteropleura, the upper part of the sternopleura and on the hypopleura; there are long, white hairs on the metapleura and on the middle of the mesopleura. Abdomen black, coarsely punctate, clothed with somewhat short, depressed, silver-white pubescence; along the sides the hairs are longer and hang downwards like a fringe. Venter black, shining, with long, white hairs; on the last two segments there is a tuft of brownish to blackish hairs. — All the long hairs on the body are woolly, giving to the fly a somewhat woolly appearance. — Legs black: coxae slightly pruinose, on the outer side with long, whitish hairs; tibiae ferrugineous on the basal half, the front tibiae to a less extent and often quite black. The hind tibiae distinctly thickened from just below the base to the apex; the hind metatarsi as long as the tibige and sharply compressed with a short fringe on each margin (Fig. 16). The femora clothed with short, blackish hairs above, and with long, whitish hairs on the posterior side and below; the hairs on the tibiae are for the most part whitish, the dense pubescence on the ventral side of the hind tibiae is yellowish to white; there are some long, thin, white hairs, especially on the middle tibiae. The somewhat stronger bristles are chiefly black but may be reddish on the ferrugineou
