148. A. plurispinosa Liindbk. 

 1920. Lundbk. Vidensk. Meddel, fra Dansk naturh. Foren. 71, 28, 32. 



Male. Frons broader than high, greyish black, diill; inner bristle 

 of lower row a little below the outer and about equally distant from 

 it and from the upper supraantennal; supraantennals small, imequal, 

 the lower about half as large as the upper; the upper supraantennals 

 slightly more approximate than the inner bristles of middle row, the 

 lower direct below the upper, almost not nearer together. Antennæ a 

 little above ordinary size, black, arista very short-pubescent. Palpi 

 yellow, of ordinary size and armature. Thorax black, only slightly 

 shining, with brownish pubescence. Mesopleura bare. Abdomen 

 somewhat robust, black, dull, with narrow, paler hind margins to 

 the segments; the short hairs hardly visibly longer at the hind mar- 

 gins of the segments, but the lateral margins and the last segment 

 rather hairy; venter yellowish brown to dark brown, the hinder part 

 densely bristly as in halterata. Hypopygium somewhat small, greyish, 

 on each side there is an oblique row of four bristles which are directed 

 downwards, and above and behind these latter some smaller hairs, 

 decreasing in size upwards ; anal tube short, yellowish, dusky towards 

 the base. Legs light brownish yellow, hind femora brown at tip, 

 with a few longish hairs below the basal half; bristles on hind tibiæ 

 distinct, but fine. Wings yellowish or brownish, veins brown; costa 

 about 0,40 of the wing-length, costal divisions about as 11 — 3 — 3; 

 third vein rather thickened; angle at fork a little acute; costal cilia 

 long; fourth vein almost straight in its first part, curved upwards 

 towards the end and a little recurved at apex. Halteres yellow. 



Female. Unknown. 



Length 1,7 mm. 



This species resembles halterata in the costal divisions and the 

 course of the fourth vein, but is distinguished by the more bristled 

 hypopygium, and it is a much more black species. 



A. plurispinosa is a rare species, only three males have been taken; 

 Copenhagen ^^6 1919, Valby "/g 1920 (the author) and Holte Vio 1921 

 (Th. Mortensen); all three specimens were taken on windows. 



Geographical distribution: — Hitherto only known from Den- 

 mark.
