. Fig. (). Wing of L. guttiventris. cross-vein is not longer than the peduncle of the second posterior cell; the fourth posterior cell has no peduncle. Halteres yellow, the knob may be slightly darkened. Female. With exception of the genital differences quite agreeing with the male. Length 8—13 mm. This species is at the first glance somewhat like the preceding but on closer examination it differs in many points; especially the wings and the colour of the legs are good characters, further the pubescence of the antennal style and the colouration of the abdomen. Zetterstedt 1. c. records it as L

Zetterstedt 1. c. records it as L. guttiventris Stseger in litteris, so that the name is due to Steeger. L. guttiventris is much less common in Denmark than the pre- ceding species; Hiiler0d, Grib Skov; on Funen at Odense, Veflinge and Faaborg and in Jutland in Greisdalen, at Frijsenborg, Silkeborg, Gjess0 near Silkeborg, Hald, and Fusing0 near Randers. My dates are '^^U to August. Geographical distribution: — The species is distributed in northern and middle Europe down into Austria; towards the north in southern Scandinavia; it seems everywhere to be more rare than cylindrica. 2. DioctPia Meig. Species of middle to somewhat large size and of a more or less slender shape; the colours are dark or black, and the species are very slightly hairy, almost bare. Head somewhat broader than thorax and much broader than high; it is short and the posterior surface is flat. The eyes are large, the epistoma rather broad without any distinct or at all events only a small callus; the epistomal beard not dense. Antennae inserted very high, near to each other on a more or less prominent tubercle. The frons on account of the high inser-
