Vertex and frons grey; epistoma somewhat broad, white haired; palpi yellow, somewhat large, fully half as long as the pro- boscis. Occiput grey, with whitish bristles above, white hairs below. Antennae black or brown, the basal joints and generally also the base of the third joint yellow, the third joint somewhat elongated, but not as long as the arista. Thorax yellowish grey pruinose, with two approximated darker grey stripes in the middle, abbreviated behind; there are three distinct notopleural bristles; all bristles yellow. Scutel- lum has generally six yellow marginal bristles, of which the inner and outer pair are short, the intermediate pair • long. Pleura light grey pruinose; above the middle coxae a black, polished spot. Ab- domen black, shining; at the sides with grey bands, which are some- what large on the first two segments, small on the others; it is clothed with short, yellowish white hairs. Venter black. The exterior genitalia somewhat small. Legs yellow, tarsi brownish to blackish annulated, sometimes indistinctly, and the tarsi almost quite yellow. Front femora only slightly, middle femora somewhat more thickened. The legs are short-haired with yellow hairs. Wings somewhat yellowish tinged. Veins brownish, yellow to- wards the base; the cubital and discal vein somewhat convergent, both being curved towards each other, pig. 137. Wing-part of T. cursitans. Halteres white or yellowish white. Female. Quite similar to the male; abdomen pointed. Length 3,5—4,3 mm. T. cursitans is not precisely common in Denmark; Ermelund, Ordrup, Nyraad at Vordingborg, on Egholm at Skelsk0r, and on Langeland at Lohals; my dates are ^^ib—'^li.
