Parnassian quandary

[D Marven]

Hi Leps
Yesterday I spent the day on Mt.Arrowsmith on Vancouver Island, B.C. and
I observed what I belive to be two different species of Parnassian's on
the lower reaches and the road up to the ski hill Clodius Parnassian
(Parnassius clodius) was quite evident, but at the higher elavations a
much whiter Parnassian was observed. This species showed some faint red
spots on the upperwing and flew much slower than Clodius. Most specimens
were quite worn and I must admit I foregot to look at the antennae to
see if it was ringed or not. The problem is that The Butterflies of
Canada suggests that it is Rocky Mountain Parnassian (parnassius
smintheus), but the Checklist of North American Butterflies from NABA
does not list this species. Any help you guys could give me would be
much appreciated as this is possibly a new species for me. Derrick
