234 Phoridae. 



in the middle, only on second segment often uninterrupted; abdomen 

 may thus also be termed black with yellow hind margins and triangular 

 middle spots; first segment nearly quite yellow, only brownish on 

 the disc. Venter yellow. Abdomen is very sparingly haired with short 

 hairs, almost only visible at the hind margins of the segments; along 

 the sides they are a little longer and on the protruding sides of second 

 segment there are bristly hairs. Hypopygium small or medium sized, 

 generally withdrawn; it is yellow or greyish yellow, symmetricai, the 

 side prolongations broadly rounded, hairy; anal tube compressed, 

 somewhat large, yellow, with some longish hairs above and below;

ventral plate yellow. Legs yellow, hind femora well dilated, blackened 

 just at the tip, middle coxæ with a black spot on the posterior side; 

 the hind femora have long hairs below on the basal half; bristles on 

 hind tibiæ somewhat strong and there is besides an anterodorsal 

 row of small bristles, not reaching quite to the end; middle tibiæ 

 likewise with a posterodorsal row of bristles and an anterodorsal 

 row of smaller bristles on the basal half; on front tibiæ an anterodorsal 

 row of small bristles. Wings yellow or light brownish, veins brownish, 

 thin veins strong; costa reaching to or beyond the middle, 1 a little 

 longer than 2, but generally not as long as 2 + 3; costal cilia short; 

 angle at fork acute; fourth vein a little S-like at the base, for the rest 

 slightly and evenly curved. Halteres yellow. 



Female. Antennæ a little smaller than in the male; the antero- 

 dorsal bristles on middle and hind tibiæ more distinct; for the rest 

 similar to the male, the hind femora likewise with long hairs below 

 (Becker says that these hairs are absent, but this is incorrect). 



Length 1,5 to fully 3 mm, the small individuals are rare. 



A. picta is rather common in Denmark, Ordrup (Stæger), Dyre- 

 haven, Egebæks Vang (the author), Holte (Th. Mortensen), Bogø
