372 Phoridae, 



at the hind margin of sixth segment. I have seen some EngUsh spec- 

 imens from Mr. CoUin, but only one of them, a female type-specimen 

 from Wood, agrees with my specimens, the others I would consider 

 as angusta or tumida. — Only few of my females show the costal 

 divisions as described above, a number have 1 relatively shorter, 

 and also often the fork less acute, and as regards these specimens I 

 am not sure as mentioned below under angusta. 



A. fusca, as I understand it here, is not rare in Denmark; Erme- 

 lund, Holte, Geel Skov, Suserup Skov at Sorø, on Langeland at 

 Lohals, on Falster at Marienlyst, and in Jutland at Ry (Th. Morten- 

 sen, the author); the dates are ^Vs — "/lo in 1917 to 1921. 



Geographical distribution: — Besides from Denmark known from 

 England and, according to a specimen from Pater Schmitz, from 

 Holland.
