Antennae blackish brown, third joint large and oval, reaching beyond the middle of the eye; arista short and straight, very short-pubescent. Palpi yellow, with ordinary, not long bristles. Thorax black, a little shining, with pale brownish pube- scence. Scutellum with four equal bristles. Mesopleura bare. Abdomen black, rather slightly greyish, dull; it is exceedingly short and spar- ingly haired, only at the hind corners of second segment some small hairs more visible. Hypopygium small, symmetrical, greyish; anal tube compressed, narrow at the base, increasing in height outwards and very high at the middle, but then emarginate to the apex (fig. 83), it is yellow, more or less brownish at the base. Legs brownish yellow or Fig. 83. A. emarginata S, brownish, hind femora somewhat di- anal tube X 135. lated, with long hairs below on the basal half; hind tibial bristles of medium size, the dorsal hair-seam is strongly deflected towards the anterior in the apical third and hence the dorsal margin seen in profde is much arched. Wings slightly yellowish tinged, veins brown or dark brown; costa not reaching the middle, 1 nearly double 2 and longer than 2 + 3; costal cilia long; the outer branch of the fork slightly angulated and from here issues the fourth vein which is evenly curved in the whole length. Halteres dark or dusky yellow to light brownish. Female. I have not seen the female; according to the des crip tions, it has the frons a little less broad, the antennae of ordinary size with the third joint roundish and arista a little longer; the ovi- positor long and excerted (Wood). Length fully 1 to 1,6 mm. A. emarginata is a rare species in Denm
