A. basispinata S, deflecting anteriorly in the lower half, hind femur from the inside Wings clear or nearly so, veins brown or â yellowish brown; costa reaching to near the middle (0,47), costal divisions about as 11â7â3 (not 2 as in my first description); costal cilia long; angle at fork of medium size; fourth vein evenly curved. Halteres yellow, (in one specimen halteres darkened and at the same time the anal tube being brown with only apex yellow). Female. Unknown. Length. About 1,7 mm. The armature of the hind femora is somewhat similar to that in Beckeri, but this species has the mesopleural bristles quite uniform and black halteres. A. basispinata does not seem to be common; Copenhagen, on a window, Holte, Hillerod, and in Jutland at Esbjerg, Ry and Lokken (Th. Mortensen, the author); the dates are ^Veâ^"V? in 1917 to 1921. Geographical distribution: â Hitherto only known from Den- mark. 34. A. insons Lundbk. 1920. Lundbk. Vidensk. Meddel. fra Dansk naturb. Foren. 71, 5. Male. Frons about 1^/2 times broader than high, grey, dull; inner bristle of lower row somewhat below the outer and in nearly the same distance from it as from the upper supraantennal; supra- antennal bristles not large, approximate, the lower rather close to the upper and a little smaller. Antennae black, of ordinary size, arista distinctly pubescent. Palpi yellow, ordinary. Thorax black, very slightly or almost not shining, with, brownis
