290 Phoridae. 



imen was kindly sent to me from Pater Schmitz who at the same 

 time told me that Becker's type was not to be found; I have also seen 

 specimens from Wood, so that I feel sure in imiting Dahli and humilis; 

 when Becker gives the coloiir of legs and halteres paler, it is, I think, 

 because the specimens were preserved in alcohol; when Wood says 

 that the front tarsi in the male are not longer than tibiæ, this is 

 erroneous, as his specimens prove; the tibiæ are not much longer than 

 the three first tarsal joints; the "sort of projection or shoulder breaking 

 the outline of the under-side", which Wood mentions for the hind 

 femora, is, as mentioned above under fungivora, only due to exsicca- 

 tion. — The hairs below hind femora in the male seem to be Kable 

 to some variation, some of my specimens showing them less dense 

 than others. 



A. Dahli is not just rare in Denmark; at Copenhagen in Frede- 

 riksberg Have, in Ermelund, Geel Skov, and in Jutland at Hejls 

 south of Kolding and at Jelling (the author); the dates are ^7« — ^^9; 

 at Hejls it was taken somewhat numerously, especially on flowers 

 of umbeUifers. I took it for the first time in 1913, but in Stæger's 

 collection there is an old specimen, placed under rufipes. 



Geographical distribution: — Denmark, England, Holland and 

 Germany.

Male. Frons somewhat broader than high, black, dull; inner 

 bristle of lower row slightly below the outer and nearer to it than to 

 the upper supraantennal; supraantennal bristles unequal, the lower

 conspicuous at the hind margins and a little longer at the sides; at 

 the hind margin of sixth segment the hairs are somewhat long, especi- 

 ally at the sides. Hypopygium small, greyish black, on each side with
