Halteres black. — Female. Similar to the male, front tarsi constructed in the same way, the middle joints fully as stout; wings with the fork longer but the angle the same. Length 1,^ — 1,7 mm. Ermelund \s 1918, Dyrehaven Ve 1919, Lyngby Mose ^Ve 1918 and Ry in Jutland "Vt 1918 (the author) ; three males and three females. 11. A. nigripalpis n. sp. J*.

Frons considerably broader than long, black, slightly greyish; bristles strong, inner bristle of lower row somewhat below the outer and nearer to it than to the upper supraantennal ; supra- antennal bristles unequal, the lower pair somewhat weaker than the upper; the upper supraantennals approximated, a little nearer together than the inner bristles of middle row, the lower supra- antennals still a little more approximated. Antennæ black, a little above ordinary size, arista distinctly pubescent. Palpi of fair size, black, the bristles rather strong. Thorax black; mesopleura bristly, the bristles equal. Scutellum with two bristles. Abdomen black, very slightly greyish. Hypopygium not large, on each side with three or four bristles below in a somewhat oblique row continued upwards in three vertically placed bristles; anal tube of medium size or somewhat small, black. Legs black, the front legs slightly paler, last joint of front tarsi deep black ; front tarsi dilated, the metatarsus almost as broad as tibia ; the hairs below the basal part of hind femora short and not dense; bristles on hind tibiæ some- what small, not numerous, about 12 in number. Wings quite clear, thick veins blackish, the others almost colourless; costa reaching to the middle, costal dtvisions proportionately as 13 — 7— 4; costal cilia long; fourth vein evenly curved. Halteres black. Length 1,8 mm. Ermelund ^Ve 1919 (the author); one male.
11 12. A. longiciliata n. sp. J* A species related to nigripes Wood and Beckeri Wood but dis- tinet from both. Male. Frons greyish black, somewhat broader than long; brist- les strong, inner bristle of lower row somewhat below the outer and nearer to it than to the upper supraantennal; supraantennals unequal, the lower about half as strong as the upper; the upper supraantennals more approximated than the inner bristles of the middle row, the lower direct beneath the upper. Antennæ of or- dinary size, blackish, arista distinctly pubescent. Palpi yellow, well developed, with ordinary bristles. Thorax black; mesopleura bristly, the bristles equal. Scutellum with two bristles. Abdomen black, very slightly greyish, somewhat robust. Hypogygium not small, greyish, produced downwards and thus higher than iong; there are no hairs or bristles visible; ventral plate yellowish, rounded at the end, reaching about to the end of the hypogyium ; . anal tube some- what small, brownish, a little paler at apex, the apical hairs small. Legs light brownish, hind tibiæ only slightly longer than the two first tarsal joints, the bristles small. Wings somewhat brownish tinged, veins brown, the thin veins somewhat strong and the seventh vein only sligthly finer than the others; costa not reaching to the middle, 0,47 of the wing-length, costal divisions proportionately as 11— 5— 3; angle at fork somewhat acute; costal cilia long, longer than usual ; fourth vein evenly curved. Halteres black. Length 1,6— 2 mm. From superciliata Wood which may have the costa on the border between short and long the present species is distinguished, besides by the longer costa, by the unequal supraantennals, black halteres, not straight searn on hind tibia and larger size. Holte Vt 1917 (Th. Mortensen), Bogø south of Sealand Vt 1917 and Ry in Jutland ^V? 1918 (the author) ; three males. 13. A. consimilis n. sp. c? ?. A species near the foregoing but much smaller, with clear wings and longer hind tibiæ. Male. Frons greyish black, somewhat broader than long; inner bristle of lower row in, or nearly in the same height as the outer
