262 Phoridae. 



not stouter than usual; hind femora with only short hairs below the 

 basal half, but the hairs on the anteroventral margin of the apical 

 part somewhat long and bristly; hind tibial bristles distinct, but 

 weaker than in rudis. Wings as in rudis, but more colourless, and 

 thin veins rather fme; 1 distinctly longer than 2+3; costal cilia 

 rather midway between short and long; angle at fork likewise large. 

 Halteres black. 



Female. Similar to the male; antennæ small and the hairs on 

 the apical part of hind femora much smaller. 



Length 1,3 — 1,7 mm, 



This species is, as seen, very similar to rudis, but besides by some 

 small characters, as the frontal bristles and the breadth of frons, 

 it will be known by the want of the long hairs below the basal half 

 of hind femora and by the bristly hairs below the apical part; the 

 female may, I think, likewise be recognized by the frontal bristles 

 and short hairs below basal half of hind femora; from pseiidociliata 

 it is likewise distinguished by the want of long hairs below hind 

 femora, and pseudociliata is a larger species with still larger antennæ 

 and the mesopleural bristle longer. 



A. depilata is rare, I possess eight males and one female; Holte, 

 Geel Skov, Suserup Skov at Sorø and in Jutland in Egense Skov 

 at the east end of Limfjorden (Th. Mortensen, the author); the 

 dates are Vt— 'Vs in 1917 to 1921. 



Geographical distribution: — Only known from Denmark. 



25. A. limburgensis Schmitz. 



1918. Schmitz, Entom. Ber. Nederl. Ent. Ver. V, 57. — 1919. Schmitz, 

 Jaarb. Natuurh. Genootsch. Limburg 1918, 155. 



Male. Frons slightly broader than high, black, a little greyish, 

 dull; inner bristle of lower row well below the outer and in about 

 the same distance from it and from the upper supraantennal, but a 

 little varying in position sometimes rather low and somewhat nearer 

 the eye-margin; supraantennal bristles unequal, the lower scarcely 

 half the size of the upper or smaller; the upper supraantennals about 

 in the same distance from each other as the inner bristles of middle 

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

 or blackish brown, arista not long, short-pubescent. Palpi dusky 

 yellow, rather small and with rather short, sometimes a little longer 

 bristles. Thorax black, a little shining, with brown pubescence.
