In genitalia schulziana and internustana are very similar. The 

 European species is somewhat larger and often more reddish; but 

 otherwise I can see no real difference. The question of synonymy, 

 however, will have to remain in abeyance until a typical specimen 

 can be recovered from Arctic America. In the Canadian National 

 Collection there are a number of specimens from Quebec, Alberta, 

 and Quebec, Labrador under the name. They are quite dark how- 

 ever (blackish rather than red) and \Qvy variable. I have little 

 doubt but that they are color or local varieties of schulziana.

In size, color, and general appearance intermistana and turfosana 

 are much alike. The two differ genitalically in the length of the 

 spined lower margin of the harpe, and there is no doubt of their being 

 distinct species. It is my opinion that the European species does not 

 occur in our fauna, and that what Moschler took for it was a speci- 

 men of intermistana.
