Most of the Northern specimens are greyish, whitish-grey 
or white on the underside, but in some cases, when sympathet- 
ically examined, or when the whitish bloom has worn off, may 
be said to fit in with the “dark grey” of Edwards’ very poor 
description. 
scudderi scuddeyi Edw. 
Male. Upperside: rather strong terminal line; discernable 
insulae in secondaries. Underside: greyish; fuscous spotting 
delicate but fairly distinct; white arches ray-like in secondaries, 
i.e. separated throughout by the greyish ground along the vein 
(a character not represented in my melissa material) and fused 
with the extradiscal halos; fuscous arches on both wings fairly 
strong, though not distinctly pointed; fulvous arches weak, thin, 
disconnected from praeterminal spots (a character found also 
in “weak” specimens of argyrognomon anna and in some melissa 
annetta ) by the ground which is quite whitish towards the 
termen; praeterminal spots in secondaries touched up with 
(“aquamarine”) optical scales conspicuous only in Cu x and an- 
nally; quite strong terminal line with well-developed triangles 
and cilian points. [Extradiscal spot in Cux aberrationally dis- 
tended as it was in Edwards’ type specimen.] 
Male, neotype, “Saskatchewan. Kennicott.” Slide No. 168.

This description holds good for most Northern individuals of 
scudderi scudderi (except that the iridescence may develop in a 
greater number of spots and that the ground may be quite white 
throughout with a pale blue dusting of basal optical scaling). 
Northern females are generally “blue” with, if at all, weakly 
developed fulvous arches, upperside. My material comes from: 
Saskatchewan (“Narlan”); Manitoba (“McCreary,” “Beulah,” 
“Riding Mts.”) ; Minnesota (“Pequot,” “Arrowhead Trail”); 
Brit. Col. (“B.C.,” “Atlin,” “Heffley Ck.”); Alberta (“Foot- 
hills,” “Banff,” “Jasper”) ; and Yukon (“White Horse,” 
“Mayo”). If, as I believe, the Yukon insect figured by Gibson 
(1920, Rep. Can. Arct. Exp. 3, pi. 3, fig. 15, male) is a speci- 
men of scudderi scudderi , then it is its first and only representa- 
tion. 
From “Mt. Rainier,” Washington, I have a series of remark- 
able scudderi specimens expressing the same variation as 
annetta does for melissa and as ricei (if correctly identified)
