414 Phoridae. 



a type-specimen from Pater Schmitz and it seems to me to agree well 

 with my average-specimens ; the type-specimen has yellow balteres. 

 Schmitz describes the hypopygium with two bristles, but in a letter 

 to me he has declared that he had found latér on that there are in 

 reality three. The species is nearly related to halterata, but is in the 

 male distinguished by the bristles on hypopygium being more than 

 two, and in both sexes by the length of costa, the costal divisions and 

 the course of the fourtli vein. I possess a large material, but perhaps 

 more than one species are hidden in it; I am, however, at present 

 unable to find distinguishing characters. 



A. fuscohalterata, as taken above, is common in Denmark, much 

 more common than halterata; Søndermarken, Gentofte, Ørholm, 

 Geel Skov (the author), Holte, Hillerød, Alindelille, Suserup Skov at 

 Sorø (Th. Mortensen), Bogø south of Sealand, Stensby Skov in South 

 Sealand, on Langeland at Lohals and in Jutland at Hejls south of 

 Kolding, Jelling, Ry and Laven (the author); my dates are Vs — ^Vio 

 in 1917 to 1921. I have never taken it on windows. I took it in copula 

 on ^"/g, the male of this mated pair was black, the female paler with 

 a yellowish red thorax. 



Geographical distribution: — Hitherto known from Denmark 

 and Germany.

1920. Lundbk. Vidensk. Meddel, fra Dansk naturh. Foren. 71, 27, 31. 



Male. Frons rather broad, IV2 times as broad as high or still 

 broader, grey or blackish grey, dull; bristles strong, inner bristle of 

 lower row below the outer and nearer to it than to the upper supra- 

 antennal ; supraantennal bristles not large, unequal, the lower scarcely 

 half as large as the upper; the upper supraantennals a little more 

 approximate than the inner bristles of middle row, the lower not or 

 slightly more approximate. Antennæ above ordinary size, reddish 

 to dark brown, arista apparently almost nude. Palpi yellow or pale 

 yellow, somewhat narrow, the three apical bristles well developed, 

 the others shorter. Thorax varying from blackish brown to red, a 

 little shining, with brown pubescence. Pleura brown or red, palest 

 anteriorly. Mesopleura bare. Abdomen black, dull, often with very 

 narrow, paler hind margins to the segments; the basal half of the 

 first segment, the fifth segment and a triangular basal spot on the 

 sixth segment yellow or red; these colours may be rather obscured,
