pair at about tlie iipper third and a very small anterior bristle at

 of medium size, arista more pubescent. Palpi narrow, with short

T. intermedia is perhaps not rare in Denmark, but I know it 

 only from two localities, Ordrup Mose and Vesterfælled; in Ordrup 

 Mose I can take it in great numbers every year in April and especially 

 in May, I have taken it between ^^4 and ^Vs; it occurs always only in 

 grass on the field, but never in other low herbage; the female seems 

 to be of rare occurrence for although I have swept the male in abun- 

 dance I have got only one female; I took it for the first time in 1917, 

 but two specimens have been taken on Vesterfælled on Vs 1908 and 

 '^4 1914 (C. Larsen). 



Geographical distribution: — The species is known from Denmark, 

 Germany and England.
