ON SOME LEPIDOPTERA FROM WEST OF HUDSON’S BAY. 
133 
Oolias ( Pelidne ) var. Christina, W. H. Edwds. Of this a large number of examples, S 9 , were received, mostly of extraordi- 
nary great size, the largest (S) being 2-f inches in expanse, and the smallest (S) If inches, the average size is 2 inches. That of the 
typical N. Labrador Pelidne is about 1J inches. In shade of colour the majority of examples are same as the N. Labrador ones, the 
S lemon yellow, the 9 greenish white; but several of the males which were taken near Lake Athabasca have the upper surface suf- 
fused more or less with orange similar to those mentioned and figured in W. H. Edwards’ Butt. N. Am., the originals of which 1 have 
also seen ; with the exception of this orange suffusion they differ not a particle from the citron coloured ones. About one-fourth of the 
females are lemon coloured ; these yellow females show no traces of the blackish margin on upper surface of wings; this form is figured 
also in Edwards’ work. On the under surface the various examples exhibit every degree of depth in the greenish colour of hind wings, 
some being quite pale yellowish green, others as dark as the darkest of the N. Labrador examples; one male has the row of submar- 
ginal points and two females have the little reddish brown mark on costa. Mr. W. H. Edwards in describing Christina mentions that 
“ in three specimens out of four there were no traces of the submarginal points.” His males were all of the orange variety ; the greater 
number of those received by me were of the yellow form ; Mr. Edwards’ examples w r ere from Slave River, farther west than mine; he 
had obtained thence however no white female or lemon coloured male. All my males from near Hudson’s Bay were yellow, most of 
the females white; those that I received from further west (for they were obtained in various localities from Hudson’s Bay to near 
Lake Athabasca) had both white and yellow females and orange as well as yellow males; I know of only one orange male ever having 
been taken in N. Labrador, which example was received from there by Mr. Moschler and by him described in Wien. Ent. Mon. IV, p. 
354, (1860). No yellow female I believe has yet been found in N. Labrador, but on the southern border along the St. Lawrence River 
and in Canada and along the shores of Lake Superior the females are always yellow. This more southern form is about the same size 
as those from more northern Labrador. 
From all these facts I would deduce the conclusion that the further west we trace this species the more will we find the orange 
colour to prevail in the males and the yellow in the females, and that the white females, if they occur at all in South Labrador or west 
of Lake Athabasca, will be the rare exception. Remarkable as is the difference in colour in the various examples, it is only a matter 
of usual occurrence with the Coliades, for a more difficult group to define or in which to designate the limits of a species is not to be 
found, and a far more wonderful instance of difference in colour of males is found in C. Libanotica and C. Sagartia, both forms of the 
same insect, in which the male of the first is red and that of the second greenish blue. I am also informed that intermediate forms 
between the two occur in which the red and blue colours are intermixed. Mr. Edwards has figured a male example of Philodice that 
is orange, I also possess a U of the same colour. C. Helichta is also an orange form of C. Prate (or perhaps as has been suggested 
is a hybrid between Erate and Edusa) Of one thing I am most certain, that the Americans have made far too many species by giving 
to each local variation a different appellation and with a view to trying to do something towards solving the riddle I have given as 
much attention as possible to this beautiful and most interesting genus, having with a few exceptions obtained all the known species 
and varieties. Whilst writing the above I have before me twenty-seven S 9 Pelidne from N. W. Labrador, forty from British Col- 
umbia from a region extending from Hudson’s Bay to Lake Athabasca, five from South Labrador on the Gulf of St. Lawrence, 
and seven from Colorado. I have examined the types of Christina, Labradorensis, Scudderii, Interior and Laurenlina, and can only come 
to the conclusion that they are but three forms of one species of which I here give a short diagnosis :

This is the typical N. W. Labrador form of small size and with 9 always white, and the S yellow, with the single orange 
coloured exception previously alluded to.

Occurs in Colorado but differs in nothing of any importance from the Labrador examples, except that the 9 is occasionally, 
though not often, yellow like the S-

A form found in S. Labrador and in the Lake Superior region, in which the 9 is in the majority of instances yellow like the 
S i this bears the same relation to the N. Labrador form as does the C. Werdandi, H-S. (nee Zett), to the typical C. Palceno. 
var. b. Christina, W. H. Edwds., Proc. Ent. Soc., Phil., II, p. 79, (1863) ; Butt N. Am., I, t. II, Col., (1868). 
This is the form of great size found west of Hudson’s Bay in which the male is sometimes orange and sometimes yellow, and the 
females both yellow and white. 
Coljas Palasno, L. About twenty-five examples taken, of which seventeen, 9 S, 8 9, are before me. They are all of smaller 
size than the average of those occurring in Europe, the smallest (S') expanding If inches and the largest ( 9 ) a trifle over If inches; 
othenvise the males differ only in the yellow colour which is a little less intense; the females also agree with the trans-Atlantic exam- 
ples ; two are the yellow form known as Werdandi, H-S., all the others are white; the black marginal bands in both sexes present the 
same differences of width and outline found in their European congenors, some of the females having this band immaculate and in 
others enclosing spots of the white or yellow ground colour. 
W. H, Edwards has figured both sexes of this species in his Butt. N. Am. under the name of C. Helena, which he subsequently 
changed to Chippewa. So close is his female figure to one of the examples before me that it seems almost as if the latter had served as 
the original of it. I here append the synonymy of this species :
