322 Phoridae. 



in this sex the divisions are upon the whole as in the male, and also 

 here 1 may be longer; I possess females with the proportions of 1 to 

 2 4- 3 as 19 to 16; Wood says that abdomen has no trace of any grey- 

 ish gleam, I find it distinctly greyish. The stoutness of the front tarsi 

 is sometimes very slight. 



A. variabilis is very common in Denmark all over the country 

 including Bornholm; my dates of capture are ^^U — ^"/n in 1917 to 

 1921, but there are besides some old specimens in Stæger's coUection, 

 placed under rufipes. As seen above the species occurs during the whole 

 season; it is taken in woods on leaves of bushes and in low herbage. 



Geographical distribution: — Besides in Denmark occurring 

 and common in England and, according to specimens from Pater 

 Schmitz, in Holland; perhaps also occurring in Germany (Schmitz, 

 Tijdschr. v. Entom. LXIV, 1921, 8).

Male. Unknown. 



Female. Frons nearly 1^/2 times as broad as high, greyish black, 

 dull; inner bristle of lower row very slightly below the outer and 

 almost in the middle between it and the upper supraantennal, these 

 six bristles placed on a straight or slightly convex transverse line; 

 supraantennal bristles unequal, the upper large, the lower somewhat 

 smaller; the upper supraantennals more approximate than the inner 

 bristles of the middle row, the lower still more approximate. Antennæ 

 somewhat small, blackish brown, arista somewhat long, distinctly 

 pubescent. Palpi yellow, with long bristles. Thorax brownish black 

 above, slightly shining, with brownish pubescence; the lateral mar- 

 gins, humeri, scutellum and pleura more or less brownish or reddish 

 brown. Mesopleura with uniform bristles. Abdomen black or greyish 

 black, venter a little paler; third tergite abbreviated, being shortest 

 in the middle, longer towards the sides and thus with the hind margin 

 excised; the hairs at the sides of abdomen are rather distinct on 

 second segment. Legs yellow, hind femora very slightly darkened 

 just at apex; bristles on hind tibiæ small and numerous. Wings strongly 

 brown, veins strong, brown to blackish ; costa well beyond the middle, 

 costal divisions about as 10 — 6 — 3; costal cilia fuU long; fork longish 

 and the angle somewhat acute; fourth vein S-like curved at the base
