312 Phoridae. 



somewhat shining, with brownish pubescence. Mesopleura with uniform 

 bristles. Abdomen black, dull; the short hairs a little longer at the hind 

 margins of the segments and here increasing in length behind, on 

 fifth segment they are already a little longish, and at the hind margin 

 of sixth segment they are very long all round, as long as the segment 

 itself and bristly; also along the sides of fifth and sixth segments the 

 hairs are somewhat long. Hypopygium not small, especially somewhat 

 long and the side parts prolonged backwards below in a little projec- 

 tion; on each side there is an a little oblique or nearly vertical row of 

 about five bristles and still two bristles longer upwards; there is a 

 small, somewhat spatula-shaped, yellowish ventral plate, broadest at 

 the end; anal tube not large, brownish. Legs brown, front legs only 

 slightly paler; the hind femora have below in the proximal two thirds 

 a fringe of distinct, but not long hairs, which are shortest at the base, 

 longish towards the end ; bristles on hind tibiæ of about medium size, 

 not numerous. Wings somewhat yellowish brown, veins brown or 

 pale brown; costa not quite reaching to the middle, about 0,48 of the 

 wing-length, costal divisions about as 3 — 2 — 1; costal cilia long; 

 fourth vein curved at the origin, for the rest nearly straight; seventh 

 vein quite straight. Halteres yellow. 



Female. I possess a female quite agreeing with the male, but 

 with the costa longer, quite to the middle, and of course without 

 special hairs on abdomen; I think it very probable that it belongs 

 here, but cannot be quite sure. 



Length 1,6 mm. 



A. chaetopyga is very rare, one specimen, a male, was taken in 

 Ermelund ^"/s 1920, and the mentioned female was taken in the 

 same locality ^Vs 1921 (the author). 



Geographical distribution: — Hitherto only known from Den- 

 mark.

 1920. Lundbk. Vidensk. Meddel, fra Dansk naturh. Foren. 71, 13, 15. 



Male. Frons rather broad, but not twice as broad as high, greyish 

 black, dull ; inner bristle of lower row about in the same height as the 

 outer and nearer to it than to the upper supraantennal, these six 

 bristles forming a nearly straight, transverse row; supraantennal 

 bristles unequal, the lower not more than half as strong as the upper; 

 the upper supraantennals as distant as the inner bristles of middle row, 

 the lower sHghtly more approximate. Antennæ black, of ordinary size.
