short, but distinct hairs, a little longer at the hind margins of the 

 segments; at the hind margin of sixth segment the hairs are long. 

 Hypopygium of a curious shape, it is not small, but quite short, 

 black or brownish black and shining; it is quite open behind so that 

 the aperture for the anal tube is large; at the hind margin it has 

 long and dense, overhanging hairs all round, and below on the sides 

 there is a cbuple of bristly hairs among which one bristle; there is a 

 yellowish, triangularly pointed ventral plate below; anal organ 

 relatively small, yellowish or somewhat dusky, and it is hairy, but 

 without the usual two apical hairs; not rarely the hypopygium is 

 more or less withdrawn. Legs brownish or yellowish brown, the hind 

 legs the darkest; the four last joints on front tarsi are relatively broad 

 and the last dilated and blackish; hind femora rather broad, especially 

 about the middle, the ventral margin in the basal half a little concave ; 



below the basal half there 

 is a fringe of somewhat 

 long and strong hairs with 

 the apices curved back- 

 wards, they are shortest

 longer than 2, but shorter than 2+3; costal ciha very long; angle 

 at fork not large; fourth vein with a distinct curve in its basal part, 

 for the rest nearly straight. Halteres yellow. 



Female. Similar to the male; frons less broad; antennæ a little 

 smaller; front tarsi simple with the last joint not dilated and the hairs 

 below hind femora short, but forming a somewhat distinct fringe; 

 first costal division relatively longer, generally equal to 2 + 3. 



Length 2 to fully 2,5 mm. 



A. Woodi I have taken almost only in one single locality, Geel 

 Skov, but here it is rather numerous, only one pair has been taken 

 at Hillerød (Th. Mortensen); the dates are '/s— 'Vio in 1918 to 1921; 

 it is thus late occurring and is evidently an exclusively antumnal 

 species; it was taken on leaves of Acer, and many of my specimens 

 I have taken on a single bush in the outskirt of the wood at a road. 

 I have taken it in copula on Vio- As seen above the species has only 

 been taken in recent time, but, as mentioned under the family,
