 cell. Hind wing about as in P. ochosalis. 10 mm. 



Western Pennsylvania to Illinois and Manitoba. New York: Fentons (Lewis 

 County), Newport, Lancaster, Buffalo, Karner, Sloatsburg. I have verified none of

In variety cinerosa Grote and Robinson, the yellow is replaced by olive, and the 

 rose by dark purple, or sometimes the whole moth is dull olive.
