dark brown; costa reaching beyond the middle; costal divisions as 

 15 — 10 — 6, thus 1 about equal to 2 + 3; costal cilia long; the fork 

 extremely long, so long that the outer branch is as long as the second 

 costal division, the angle acute; foiirth vein issuing behind the base 

 of the fork, below the middle of the outer branch, it is well curved 

 in its first part, the apical part straight. Halteres yellow. 



Length. About 2 mm. 



This species is, as seen from the description, near pulicaria, but 

 distinguished by the extremely long fork; though the fork is rather 

 varying in pulicaria I do not think it possible that the present species 

 can be a variety of pulicaria. 



A. longifurca is rare, only one specimen, a female, has been taken, 

 Lohals on Langeland ^'Z? 1920 (the author). 



Geographical distribution: — Hitherto only known from Den- 

 mark.
