 femora with a broad blackish ring, tibiæ a little infuscated before 

 apex and last tarsal joint blackish; hind femora shining below and 

 on the posterior side; the legs short-haired, femora with a very faint 

 pale ciliation behind, best developed on middle femora; all femora 

 with two rows of small spinules below the apical part. Wings slightly

 than next costal segment, middle cross-vein beyond the first third

Female. Frons somewhat broad, broadest in the middle, grey, 

 but black and shining above. Antennæ with the third joint paler 

 than in the male, a little more pointed. Abdomen somewhat in- 

 curved, shining, the three first segments grey pruinose, and the 

 fourth slightly or not strongly shining, this and the following grey 

 at the sides; hypopygium not large, the basal part roundish, shining, 

 the reddish ovipositor short, thin and straight. Legs paler than in the 

 male as the rings on femora are smaller and not complete behind. 

 Wings with the stigma a little shorter than next costal segment. 



Length about 3 mm or fully. 



P. semijumosiis is rather rare in Denmark, Frederiksberg 

 (Stæger), Dyrehaven (Schlick), Ermelund, Lyngby Mose, Geel Skov 

 and in Jutland at Hejls south of Kolding (the author); my dates 

 are ^li — ^7io, thus it is no early species. 



Geographical distribution: — Northern and middle Europe from 

 Scandinavia down into Styria. 



Remarks: Becker is (1. c. 1921, 158) of opinion that Strobli 

 Verr. and strigulipes Verr. are only slight variations of semifumosus 

 and in this I agree the more so because Verrall expresses himself the 

 same possibility.
