John, I have been working on this confusing group at my place and would tend to favor P. Canadensis because of the lack of the strong black upside down C on the inside margin of the black ST line of the Hind wing and the lack of the dark dot just below the PM line.

Obviously, I cannot make a species call, but that is my opinion.
