Phoridae. 



between the apex of the first vein and the end a little thickened; 



costal divisions about as 7 — 3 — 2; costal cilia short or moderately 



short; angle at fork somewhat large, fourth vein evenly and not 



much curved. H alteres yellow. 



Female. Similar; frons a little narrower, quadratic or about; 



front tarsi less thickened, the thickening, however, still observable; 

 the fourth to sixth abdominal tergites are narrow, 

 the fourth being suddenly considerably narrower 

 than the third, while the fifth is a little broader than 

 the fourth, abdomen thus being a little constricted 

 at the fourth tergite (fig. 118); this character is 

 obvious on fresh specimens but often not easily 

 seen on dried material. 

 Length 1,2 — 1,5 mm. 



A. tarsalis is not rare in Denmark, though in 

 no way common; Ermelund, Geel Skov, Ørholm 

 (the author), Holte, Suserup Skov at Sorø (Th, 

 Mortensen), Stensby Skov in South Sealand, Bogø 

 south of Sealand, on Langeland at Lohals, and in 

 Jutland at Hejls south of Kolding, Jelling and Ry 

 (the author); the dates are ^^4 — ^Vs in 1917 to 

 1921. I have taken it on bushes and with the net in 

 low herbage. 

 Geographical distribution: — Besides in Denmark occurring in 



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



also in Holland.

 slightly greyish, a little shining, or sometimes more; inner bristle 

 of lower row below the outer, nearer the eye-margin than the middle
