Specimens from Saskatchewan determined by Kearfott as this 

 species are hipartitana. I am inclined to a^^ree and to refer dilutifus- 

 cana to the synonymy, except for the fact that Walsingham has taken 

 particular pains to distinguish his species from hipartitana. The 

 variability of the latter, however, invalidate the characters he uses 

 for separation. On the other hand the type locality of dilutifus- 

 cana seems to be somewhat outside the laiov.m range of hipartitana. 



There is a specimen from Walsingham in the Fernald Collection 

 labeled " Type " which equals urticana Hiibner, I have some doubts, 

 how^ever, that this supposed paratype is correctly identified, and 

 until the genitalia of the actual type can be examined it were better 

 to keep the Walsingham name out of synonymy. 



Alar expanse. — 16 mm. 



Type. — In British Museum. 



Type locality. — Southern Oregon.

I do not think there can be any reasonable doubt of the above 

 synonymy. We have a paratype of fuscaZhana in the National 

 Collection, and it agrees in genitalia with castorana and what Fernald 

 and others have identified as glaciana. Walker's dealhana I am 

 placing here on the strength of Walsingham's description and figure 

 and Knight's very careful figure in the xlmerican Museum. Kear- 

 fott usually determined specimens of urticana as dealhana. This I
