apex of'jDrimaries and the greater part of the exterior margni are of 

 vitreous scales. The only markings on secondaries being the black 

 basal margin fading out towards median cell, and a prominent discal 

 spot. 



The females are of the hennodnr order — dark, the entire apical 

 and outer marginal part being transparent on primaries; the two sub- 

 costal red spots always looking faded. No other red markings on 

 jDrimaries. Secondaries are equally dark and vitreous along exterior 

 margin; the red ocelli marked with whitish centres and all the black 

 delineations prominent. Expanse of wings: S , i3<^ inch.; 9, i/8 

 inch. 



Our present nomenclature of P. sinintheus stands as follows: 



Parn. smintheus Doubl.-Hew. 

 iiitcnnedius M^n. 

 Var. behrii Edw., Nevada, Utah. 

 Var. sedakovii Men. , Colorado. 

 Var. hermodur Hy. Edw., Colorado. 

 Var. 7iatiHS Neumoegen, British Columbia and Montana. 



I do not understand why the var. sedakovii, where there are no 

 red markings in primaries and at times some in a universal way only 

 in secondaries, has never been mentioned in any of our catalogues. 

 It is to be found in the canyons of middle and south Colorado, and 

 occasionally in Montana and British Columbia.
