There is no real difference in structure or pattern between the 

 European ochroleucana and our supposed American species. The 

 latter is variable in size and to some ext nt in color; but there is a 

 complete series of intergrades between the smallest eastern nim- 

 batana and the largest California consanguinana^ and also between 

 both these and typical ochroleucana. The genitalia show no varia- 

 tions of any significance. At most our American form can be no 

 more than a local race. I do not see anything however to separate 

 it even as such. 



Male and female genitalia figured from specimens in National 

 Collection from Plumas County, Calif. (June).
