Kearfott's pseudotsugana is plainly a synonym of pinicolana 

 Zeller. The character he gives for separating the two (that is, 

 whether the dark markings incline to lead gray or brown) is by no 

 means constant. Authentic European specimens of picicolana show 

 considerable variation and the typical pseudotsugana is included in 

 its forms. There are no appreciable genitalia differences in the 

 two. The reference of pinicolana as a synonym of diniana Guenee 

 I have accepted on the authoritj^ of the European lists.
