. Diptera Danica: genera and species of flies hitherto found in Denmark. Diptera. 424 Phoridae, tinged, veins brownish yellow; costa short, about 0,40 of the wing- length; 1 about double 2 + 3; costal cilia short; mediastinal vein not observable; fourth vein shallowly curved in its first part and slightly recurved towards apex. Halteres yellow. Female. Similar to the male; antennae almost of the same size; the hairs representing the anterior scutellar bristles generally stronger. Abdomen with the first segment reddish, the next three black, but the second reddish at the sides; the fifth segment orange, brownish on the thinner apical part. Abdomen is of a curious construction; I shall here describe it as it presents itself for a simple examination, as regards the real numbering of the segments referring to the above generic description. The third segment has on each side at the front margin a small, flat papilla; the fifth segment is large, but has no chitinized tergite, at the base it has a large, quite membraneous area, which is clear and translucent in the living specimens; the end of abdomen is long and narrowed, ovipositor-like, the sixth segment has long, erect hairs round the hind margin; the last segment is chi- tinized, its hind margin is obliquely cut and has on each side a small, upwards pointing, black tooth; the segment is clothed with hairs below. Length 1,6—2,5 mm, the latter size is for the female with the ovipositor-like end of abdomen included. Ph. berolinensis is not rare in Denmark; Dyrehaven, Espergserde (the author), Holte (Th. Mortensen), Geel Skov, Bog0 south of Sea- land (the author), on Funen at Veflinge (H. J. Hansen) and in Jutland at Jelling and in Ry Norreskov (the author); my dates are "/s—^^Z?. My material is taken from 1912 to 1921, but at Veflinge two spec- imens were taken about 1883. The females are found on ulcerating stems of trees and may be seen hovering in swarms round such places; the male seems, like the male of fas
