Description. — Larger than P. in. aliaska Scudder (the fore wing 

 40 mm long), with the outer border of the fore wings slightly, 

 though distinctly, convex instead of straight, and the tails on the 

 hind wings shorter, although the hind wings do not differ in shape. 



On the upper side the black base of the fore wings is much less 

 heavily speckled with olive scales than is the case in P. m. aliaska; 

 the black outer border is more nearly of uniform width, not becom- 

 ing so much broadened posteriorly; the black band across the mid- 

 dle of the outer half of the cell has converging instead of parallel 

 sides, so that the costal end is much broader than the end lying on 

 the lower border of the cell ; the veins are rather less heavily black ; 

 and the black spot in the yellow triangle between veins SC4 and SC5 

 is smaller and is completely isolated from the black above and 

 below it. 



On the hind wings the inner edge of the dark border is more 

 regularly and strongly curved, so that the end of the cell is distant 

 from the dark border about the width of the cell instead of almost 

 touching it as in the case of P. m. aliaska; and the black line on the
