306 Phoridae. 



Male. Frons slightly broader than high, nearly quadratic; it is 

 greyish black, dull; inner bristle of lower row below the oiiter and 

 sometimes rather near the eye-margin, but at other times more 

 inwards; supraantennal bristles large and equal, the iipper not fully 

 as distant as the inner bristles of middle row and their distance from 

 the eye-margin nearly twice the distance from the middle line, the 

 lower supraantennals considerably longer downwards and somewhat 

 more approximate. Antennæ not large, black or brownish black, 

 arista distinctly pubescent. Palpi yellow, with well developed bristles. 

 Thorax black, nearly dull, with brownish pubescence. Mesopleura 

 bristly, the bristles few and uniform, but sometimes one or two of 

 the lowermost quite slightly longer. Abdomen black, dull; the very 

 short hairs only visible at the hind margins of the segments. Hypo- 

 pygium greyish, somewhat large and knob-shaped, as broad as the 

 sixth segment; at the lower corners a bunch of erect, small, somewhat 

 bristly hairs and the sides upon the whole rather hairy, behind the 

 hairs stretching upwards towards the dorsum, anal tube small, 

 blackish with a paler end. Legs yellowish, the posterior more brownish 

 yellow, front tarsi slightly stronger than the others; hind femora 

 only with some sparse, slightly longish hairs below on the basal half ; 

 hind tibial bristles delicate, the dorsal hair-seam deflected anteriorly 

 in the lower third. Wings clear or nearly so, veins blackish brown; 

 costa 0,46 — 0,47 of the wing-length, costal divisions proportionately 

 as 10 — 5 — 3; angle at fork somewhat large; costal cilia moderately 

 long, nearly midway between short and long; fourth vein slightly and 

 evenly curved in the whole length. Halteres black. 



Female. Similar to the male in all respects. 



Length. About 1,4 mm. 



A. proxima seems to be rare, I possess seven specimens, six males 

 and one female; Bogø south of Sealand and Stensby Skov in south 

 Sealand 'Vt— "/t 1917 (the author). 



Geographical distribution: — Hitherto only known from Den- 

 mark. 



Remarks: When I described tliis species I had only four males; 

 these all had the lowermost bristles on mesopleura slightly longer than 

 the others, the difference was small, and I was already then somewhat 

 in doubt, whether the species should belong to the group with un- 

 equal bristles; later on I found another couple of specimens, and in 

 these the difference in the size of the bristles was practically none, 

 the species thus has to be placed among the species with uniform
