Empididae. 297 



fulvipes. Frey (Acta Soc. pro Faun. et Flor. Fenn. 1909, 31, No. 9, 9) 

 suggests, that fulvipes is perhaps identical with flavipes, but I am 

 not inclined to think so, as the former has a longer third antennal 

 joint. On the other hånd the species is perhaps not to be distinguished 

 with certainty from strigifrons, as mentioned under this species. 



T. fulvipes is somewhat common in Denmark: Flellerup, Ordrup 

 Mose, Bøllemosen, Tyvekrog, Tisvilde, Frederikssund; on Langeland 

 at Lohals; on Funen at Strib; in Jutland at Hald near Viborg,. 

 Struer, Holstebro, Søndervig, Jerup near Frederikshavn, Frederikshavn 

 and Skagen; my dates are '/•; — Vo; it was taken in copula on '"Is. It 

 occurs both in woods and outside, but it seems to be most common 

 on fields. 



Geographical distribution: — Europe down into Italy; from 

 Scandinavia it is not known with certainty, unless notata in Zetter- 

 stedt is identical with it, in which case it goes to southern Sweden. 

 It occurs also in Finland. 



Remarks: I think it probable, that Zetterstedt's notata is identical 

 with fulvipes, as he mentions the species as sent from Stæger ; Stæger's 

 specimens in our coUection' labelled notata proved to be fulvipes^ 

 while notata Meig. -= fascipes Meig. has not been found in Denmark.
