This species has another European synonym, but I only quote 

 Mmaculana, as that is the name under which Zeller recorded similana 

 from Massachusetts. It is not common in America and is less often 

 taken than solandriana. 



Male genitalia figured from specimens in National Collection from 

 Medford, Massachusetts ("Sept. 20-1868"). 



Distribution according to specimens in National Collection, Ameri- 

 can Museum, and collection Barnes: Massachusetts, Quebec, New

This and emarginana Walsingham are the most variable species 

 in the genus if not in the family, as far as pattern is concerned. 

 It is easily recognized, however, and the genitalia structure is quite 

 uniform in different specimens.
