The North American population of logiana is distinguished by the 

 prevalence of grayish, sometimes rather dark-colored specimens very 

 rare in Europe. This circumstance gives reason to treat this popula- 

 tion as a separate subspecies; however, although the name placidana 

 was based on a white specimen which does not differ much from the 

 European common form, there is no choice but to apply this name for 

 the entire North American subspecies of logiana, until the gray variety 

 receives a separate name. A form with three black dots representing 

 fragments of a costal spot is known as form trisignana Robinson; 

 trisignana was described also from a white specimen, and there are 

 gray specimens too with this character.
