(??. Sexes similar. Forewiug on the whole rather more poiated than in 

 J', glauciis, the subapical e->-mark rarely centred with yellow, or at least the 

 yellow colour within the mark rarely so e.Ktt^nded as to leave only the edges of 

 the spot j)nre black, the c»-mark proximally often separate from SC, the proximal 

 portion being often almost isolated, especially on underside ; first submarginal spot 

 linear like the others, usually larger than the second ; the subbasal yellow band 

 less narrowed costally than in P. glaiicus, the third black band on the whole longer 

 than in specimens of P. glaucus of the same size, reaching usually beyond M- ; 

 yellow fringe-spots very thin. — —Black abdominal border of hiudwing always wider 

 than the yellow interspace between it and cell ; first submarginal spot small or 

 absent, seldom nearly as large as the second, never orange in either sex. 



The buff submarginal spots of the underside of the forewiug merged together 



to a continuous line. No orange patches on disc of hiudwing, or only traces of 



them ; submarginal spots less orange than in P. glaucus, usually only the last two 

 being of this colour. 



We do not tind any fairly constant differences between specimens from Arizona 

 and California. 



Early stages see Wright, l.c. 



Genitalia: 6. Harpe truncate, apex not produced beyond base of process; 

 dorsal hook longer than in P. glaucus, simple, non-dentate, there being never 



two hooks, as is always the case in P. glaucus. ? . Antevaginal process obtuse ; 



lateral dentate flaps larger than in P. glaucus, extending farther frontad than in 

 that species. 



Hab. British Columbia to Arizona. 



One of our specimens from the Frazer K. (June I'JOl) is worthy of being 

 specially mentioned. The upper submarginal spots on the upperside of the forewing 

 are rounded, being connected with the margin by means of dispersed yellow scales. 

 The submarginal spots of the underside of both wings are extended to tlie margin, 

 forming a nearly continuous marginal band, a very little of the black marginal line 

 being left at the apex of most veins.
