134 The Ottawa Naturalist. [Oct. 



eastwardly however, Dr. Fletcher having sent me specimens for 

 determination from Ontario. It is the form listed by Dr. Dyar as 

 calycanthata from the Kootenai district. Flies in May and June. 



P. MiNEREA, Guenee. More like lunata in appearance and 

 often confused with it. It is more mottled, however, and differs 

 structurally. An easy way to distinguish it is by the date; it 

 flies in May, June and Juh" and disappears before lunata comes 

 on the scene. It is found throughout the eastern provinces and 

 mingles with norda, which may be confused with it, in Ontario. 

 Dr. Bethune redescribed it as albofasciata, a well marked male 

 serving as type. It inight be said that in this and the preceding 

 species the males tend to bluish irrorations, especially in the 

 terminal area. 



P. LuNiFERA, Hubner. This is a much slighter species 

 than any of the preceding and of a more even gray tint. I have 

 no actual Canadian records; but I have it from the States just 

 south of the line, where it flies with the next species. It will 

 almost certainly be found in Ontario. 



P. LiNEOSA, Wlk. This has been confused with lunifera 

 and resembles it very much. It is yet slighter, usually paler, and 

 without contrasting maculation. I have it from points in 

 Ontario, and from Winnipeg, Manitoba, June to August. It 

 probably occurs throughout the Dominion east of the Mountains. 



P. Untlineata, Grote. A very characteristic species for 

 which I have no definite Canadian records. It has been generally 

 recorded from Canada and flies in early spring. 



P. Largera, Smith. Belongs to the series in which the 

 wings are less trigonate and the undulating very oblique trans- 

 verse lines are replaced b}?- simpler more upright maculation. 

 The types are from Vancouver Island, May 8th, collected b}?" 

 Rev. G. W. Taylor and sent in by Dr. Fletcher, (male) and 

 Winnipeg, Manitoba, sent in by Dr. Barnes (female). These are 

 the only examples of the species known to me. 



P. Duplicata, Bethune. A much smaller representative 

 of the same series and a verv distinct species. It was recorded 

 from Port Hope, by Dr. Bethune, I believe. 



P. CiNGULiFERA, Walker. I have no Canadian localities; 

 but the species occurs in Maine and other New England States, 

 so will almost certainly be found in the eastern provinces. 



P. HoRRiDA, Hubner. A common and well-known species 

 which flies from May to August and occurs throughout the 

 eastern provinces and westward, probably to the Mountains. 



From the list of species heretofore credited to Canada P. 

 calycanthata, Sm. and Ab., must be dropped. It is strictly a
