COLIAS I. 



always reaching inner angle, inclosing more or less completely fonr or five spots 

 of the c'Tound 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. 



Lakva unknown. 



PeUdrie is found a1)undautly in parts of Labrador, from far north to the ex- 

 treme south, flying in July and in company with Nastes, occasionally with Pa- 

 Iceno. 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. Mcischler a series of both Pelldne and 

 Nastes, 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 PeUchie 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 Labradorensls from Dr. Packard's specimens, 

 under the impression that these represented a distinct species from Pelldne, 

 Bois., a determination justified by the figures given in Boisduval and Leconte. 

 In the accompanying text Pelidne is described as larger than Pcdceiio, 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. Moschler, and so out of drawing as to suggest that the 

 original must have been an entirely different species fronr Pelidne, and that it 

 never came from Labrador. In the '' Icones " both sexes are given, and more 

 correctly portray the Labrador PeUdne, and in H.-Schaffer, the figures are 

 admirable both as to form and coloring. 



Much has been written on the question as to whether PeUdne is only a form 

 of Palceno or a distinct species. Mr. Moschler, in the paper cited, has compared 

 the Labrador Pelldne with the European Palceno, and concludes that there are 

 no suljstantial reasons for regarding them as varieties of one species. On the 

 other hand Mr. J. G. Schilde, in Stett. Ent. Zeit. 1873, argues that the Eurojoean 

 Palamo, the Finland Lapponica, the Alpine Werdandl, and the Labrador Pelldne, 

 are all one and the same thing, and the Labrador Pala'?io, which he allows 

 presents constant differences from the European Palamo, forms the connecting 

 link between the latter and the Labrador Pelldne. Some of the Lapponica also
