298 Phoridae. 



front tarsi distinctly though not much thickened; the hairs below 

 basal half of hind femora distinct, but not long, at most slightly 

 longish; bristles on hind tibiæ small and fine. Wings brownish tinged, 

 veins brown; costa 0,47 of the wing-length, costal divisions about 

 as 5 — 3 — 2; costal cilia moderately long; fourth vein evenly and 

 not much curved. Halteres black. 



Female. Unknown. 



Length. About 1,5 mm. 



This species, on account of its thickened front tarsi, black halteres, 

 and yellow legs is easily placed, and I think that the female therefore, 

 when it turns up, will be identified without difficulty. 



A. exclusa is very rare, only one specimen, a male, has been taken, 

 at Ørholm Ve 1918 (the author). 



Geographical distribution: — Hitherto only known from Den- 

 mark.

Male. Frons considerably broader than high, greyish black, dull; 

 inner bristle of lower row slightly below the outer and nearer to it 

 than to the upper supraantennal ; supraantennal bristles unequal, 

 the lower smaller to half the size of the upper; upper supraantennals 

 approximate, nearer together than the inner bristles of middle row, 

 the lower a little more approximate and somewhat below the upper. 

 Antennæ black, of ordinary size, arista short-pubescent. Palpi dusky 

 yellowish to dark brownish, of ordinary size and armature. Thorax 

 black, slightly shining, with dark brownish pubescence. Mesopleura 

 with uniform bristles. Abdomen black, slightly greyish, dull ; it has 

 very short hairs, almost not longer at the hind margins of the segments, 

 but a little longer at the sides, especially behind; on sixth segment 

 they are longer at the sides of the hind margin. Hypopygium somewhat 

 small, greyish black; it has a single, conspicuous, downwards pro- 

 jecting bristle on each side besides small hairs on the hind part; 

 below there is a blackish or at the apex yellow, somewhat large ventral 

 plate (Wood says small); anal tube short, black. Legs black or black- 

 ish, the front legs only slightly paler; the hind femora have quite 

 short, but dense hairs below the basal half, being densest towards
