356 Phoridae. 



Female. Similar; hind femora with similar, a little longish hairs, 

 but they seem to be shorter than in the male. 



Length 1,4 — 1,8 mm. 



A. infraposita is not rare in Denmark; Geel Skov (the author), 

 Holte, Hillerød (Th. Mortensen), Bogø south of Sealand, on Lange- 

 land at Lohals (the author), on Funen at Odense (H. J. Hansen), 

 and in Jutland at Jelling, Ry and Laven (the author); the dates are 

 ^Ve — ^Vio in 1917 to 1921. I have taken it in woods on bushes and in 

 low herbage in more or less humid piaces; the female is rarely met 

 with, while I have many males I have got only six females. 



Geographical distribution: — Besides from Denmark only known 

 from England, where it is rare.

Male. Frons broader than high, greyish black, dull; inner bristle 

 of lower row nearly in the same height as the outer and in about the 

 middle between it and the upper supraantennal; supraantennal 

 bristles equal or nearly, the upper slightly more approximate than 

 the inner bristles of middle row, the lower a little nearer together. 

 Antennæ of ordinary size and armature. Thorax black, a little shining, 

 with brown pubescence. Mesopleura bare. Abdomen somewhat robust, 

 black, dull, the short hairs the most visible at the hind margins of 

 the segments and at the sides, on sixth segment a little elongated. 

 Hypopygium greyish black or greyish brown; it has distinct and 

 longish hairs on the sides and a longer, bristly hair below at the base; 

 there seems to be a small, triangularly pointed, yellowish ventral 

 plate; anal tube short, but high, yellow. Legs light brown to more 

 blackish brown, the front legs paler, yellowish; hind femora a little 

 dilated, the hairs below the basal half somewhat long; bristles on hind 

 tibiæ not strong, but distinct and of some size; the dorsal hair-seam 

 with a somewhat sudden deflection towards the anterior in about 

 the middle or above it. Wings somewhat strongly brownish, veins 

 brown, thin veins somewhat strong; costa short, not reaching to the 

 middle (in most of my specimens only 0,44 of the wing-length), 1 

 equal to or longer than 2 + 3; costal ciha long; fourth vein only a 

 little curved in the basal part, for the rest very slightly and evenly 

 curved. Halteres vellow.
