L. 10—16 mm. 



This species, which I have been unable to identify as any 

 of the previously described species, is somewhat closely allied 

 to P. pratensis L. but is darker. This, howewer, could be due 

 to the latitude. It also differs, however, in having the wings 

 quite hyaline, and the two upper veins rising from the discal 

 cell connected at the base, whereas in pratensis the wings are 

 tinged with brown, and the two veins, in question, widly sepa- 

 rated at the base. 



Geographical distribution: Hitherto only known from 

 East-Greenland.
