COLIAS I. 
always reaching inner angle, inclosing more or less completely four or five spots 
of the ground color; sometimes the border is restricted to a narrow edging both at 
apex and on margin; secondaries usually immaculate, but occasionally a small 
cluster of dark scales is found at outer angle ; discal spot of primaries, when 
present, a narrow, black oval, with white streak ; of secondaries, small, pale 
orange; under side of primaries delicate greenish-white, apically yellow, either 
pale or dark, and this portion of the wing as well as the costal margin, more or 
less dusted with gray ; secondaries yellow densely covered with gray; discal spot 
as in male. 
Larva unknown. 
Pelidne is found abundantly in parts of Labrador, from far north to the ex¬ 
treme south, flying in July and in company with JSfastes, occasionally with Pa- 
1(2110. All these species were taken by Dr. A. S. Packard, in July and August, 
1866, on Caribou Island, Straits of Belle Isle, and at Strawberry Harbor, on the 
main land. I have received from Mr. Mdschler a series of both Pelidne and 
JSfastes, collected at Okkak, about six degrees to the north of the Straits, and 
the specimens from the two localities agree in all respects, so far as I can discover. 
I cannot learn that Pelidne has been taken on Newfoundland or Anticosti, 
but Mr. Scudder informs me that a single specimen has been taken at Water- 
ville, Maine. Mr. Scudder described Labradorensis from Dr. Packard’s specimens, 
under the impression that these represented a distinct species from Pelidne, 
Bois., a determination justified by the figures given in Boisduval and Leconte. 
In the accompanying text Pelidne is described as larger than Palceno, the 
reverse being the rule, according to Mr. Moschler, and the figures, which are of 
a male only, represent a monstrous example, nearly twice the size of any re¬ 
ceived by me from Mr. Mdschler, and so out of drawing as to suggest that the 
original must have been an entirely different species from Pelidne, and that it 
never came from Labrador. In the “ leones ” both sexes are given, and more 
correctly portray the Labrador Pelidne, and in H.-Schaffer, the figures are 
admirable both as to form and coloring;. 
Much has been written on the question as to whether Pelidne is only a form 
of Palceno or a distinct species. Mr. Mdschler, in the paper cited, has compared 
the Labrador Pelidne with the European Palceno, and concludes that there are 
no substantial reasons for regarding them as varieties of one species. On the 
other hand Mr. J. tl. Schilde, in Stett. Ent. Zeit. 1873, argues, that the European 
Palceno, the Finland Lapponica, the Alpine Werdandi, and the Labrador Pelidne, 
are all one and the same thing, and the Labrador Palceno, which he allows 
presents constant differences from the European Palceno, forms the connecting 
link between the latter and the Labrador Pelidne. Some of the Lapponica also
