the basis of Holland's figure, as is shown by the mention of a black 

 admarginal spot at the distal side of the anal ocellus. Such a spot 

 is conspicuous in specimens from the Hudson Bay region (pi. 3, 

 figs. 1, 2), but there is very seldom any trace of such a spot in 

 Alaskan examples (pi. 2, figs. 1, 2). They listed one bad male in 

 the Tring Museum, but did not give any locality for it. 



They gave the range of Pajrllio zelicaon as extending from Alaska, 

 British Columbia, and Alberta southward to Arizona and Colorado. 

 Alaska was included on the strength of Wright's record, which was 

 undoubtedly based upon a specimen of aliaska. 



In 1907, Verity under the name of joannisi described an arctic 

 form of P. 77iachaon from Alaska, which is the true aliaska of 

 Scudder, as is clearly shown by his photograph. Although Verity 

 made the error of assuming that Holland's figure represents 

 Scudder's aliaska and was thereby led to rename the true aliaska^ he 

 deserves the credit for being the first to point out the fact that 

 Papilio machaon occurs in North America in two distinct forms. 



In his account of swallowtails of the Machaon group occurring in 

 America, published toward the end of 1907 in Seitz's " Macrolepi- 

 doptera of the World," Dr. Karl Jordan said that Papilio tnacliaon is 

 represented in America by the subspecies aliaska Scudder {= joannisi 

 Verity) in which the black band on the hind wing is broader than 

 it is in the geographically nearest subspecies kamtschadalus. He 

 said that aliaska is rather common in July and August at the mouth 

 of the Yukon and other rivers, as well as in the neighborhood of 

 lakes — probably everywhere in the lowlands where Umbelliferae 

 grow. He added that eastward aliaska, occurs as far as Hudson 

 Bay. The figure he gave represents a typical example of the Hudson 

 Bay form and appears to have been taken from Holland. Doctor 

 Jordan said that kamtschadalus Alpheraky is not identical with 

 aliaska Scudder. 



In 1910, Verity described and figured a new form, which he called 

 oHentis, from the eastern part of southern Siberia. 



In 1916, Francis Kermode recorded Papilio macliaon var. aliaska 

 from Atlin, in the extreme northwest of the Province of British 

 Columbia, northeast of Skagway, Alaska, and just south of the 

 Yukon border, where it had been collected by E. M. Anderson, and 

 figured a typical specimen from that locality. 



In 1916, William Barnes and J. McDunnough published a photo- 

 graph of a male specimen of Pajnlio aliaska from Eampart House, 

 Alaska, resembling the specimen shown on Plate 2, and said that there 

 is no doubt that the form to which Scudder applied the name aliaska 

 is the form that Verity redescribed under the name of joannisi. 

 They added that the few specimens from Alaska that they personally 

 had seen had all been of the form aliaska. They said further
