pubescent. Palpi dusky yellow, of ordinary size, with well developed 

 bristles. Tliorax black, shining, with not quite short, dark brownish 

 pubescence. Pleura shining. Mesopleiira bare. Abdomen black, dull, 

 the hairs somewhat distinct at the sides and at the hind margin of 

 sixth segment. Hypopygium of medium size, somewhat glossy, with 

 hairs along the lower margins; anal tube yellow, directed downwards. 

 Legs brown or dark brown, front legs paler; the hairs below hind 

 femora distinct, but not long; bristles on hind tibiæ well developed, 

 but not large. Wings nearly colourless or slightly tinged, the micro- 

 scopical hairiness more visible than usual; thick veins blackish brown, 

 costa almost black, thin veins pale; costa reaching beyond the middle, 

 rather strong, at the humeral cross-vein with a distinct incrassation ; 

 1 about equal to 2 + 3 or a little shorter; costal cilia short and fme; 

 fourth vein rather curved in its first part, for the rest nearly straight, 

 but directed upwards and much diverging from the fifth vein, just 

 at the base it is a little obliterated. Halteres black.

 with a thickening at the humeral cross-vein. 



Length 1 — 1,3 mm. 



There can be no doubt about the determination of this character- 

 istic little species, but Wood's description is not fully agreeing; he 

 says that there is only one pair of supraantennal bristles, but there 

 are two pairs, and the lower are not specially small, about half the 

 size of the upper or even larger; I also fmd the hypopygium not large, 

 at most medium-sized. 



A. parva is rare in Denmark; Ermelund (the author), Holte, 

 Hillerød (Th. Mortensen) and in Jutland at Jelling and Ry (the 

 author); the dates are ^Vs — ^^''9 in 1917 to 1921; in all four males and 

 three females. I have taken it in grass with the net. 



Geographical distribution: — Besides in Denmark occurring and 

 common in England, Holland and Germany.
