THE CANADIAN ENTOMOLOGIST. 159 



Mountains of Alberta, may eventually prove to be the correct 

 name for the species, or it is even barely possible that I may have 

 eventually to bracket my electa with lais, but at present I certainly 

 have no evidence to justify the placing of Alberta atlantis-electa 

 material under two names. 



7. A. monticola, Behr. Banff. August. 



8. A. halcyone, Edw. Probably not rare in the foothills. I have 



examined altogether seventeen specimens, all S 6 , taken by Mr. 

 Hudson, who says it occurs both near Billings's lumber mill and 

 Lineham's lower log camp. All these bear date of July 12th, 

 though taken in different years. He also took a single J near 

 the head of Pine Creek, on July 7th, 1896, but the species has 

 not been met with elsewhere east of the spruce. In this we have, 

 judging from the verdicts of Drs. Skinner and Holland, a form 

 referable to either halcyone or coronis. Allowing for the usual 

 sexual differences, my form agrees fairly well with the figure of 

 halcyone 9 in Mr. Edwards's Butt. N. Am., except that none of 

 my specimens have the rosy tinge on under side of primaries, and 

 the silver spots in second row (of secondaries) are of less uniform 

 shape than in the plate, and the ferruginous area in no case quite 

 as dark. Many of my specimens have a decided tinge of green, 

 noticeable only in certain lights. I have not seen his plate of the 

 o* . I sent a specimen to Dr. Skinner as halcyone, which he 

 considered correct. I had sent the species to Dr. Holland, before 

 seeing Edwards's figure of $ or receiving Dr. Skinner's opinion. 

 I quote Dr. Holland's words : " It might as well be coronis as 

 anything else. I have a specimen from Mt. Judith, Montana, in 

 the Edwards collection, which agrees exactly with your specimen." 

 The black markings above in the Pine Creek specimen are much 

 heavier, and the basal area darker, than in any of those taken 

 further west. 



9. A. Nevadensis, Edw. Very common everywhere. July and August. 



It seems probable that past records of Nevadensis, Edwardsii 

 and Meadii, from Alberta, all refer to one species. I have 

 examined a large number of specimens of both sexes, taken from 

 the mouth of Pine Creek to the foothills, and from Calgary to 

 Sheep Creek, as well as some taken by Mr. Gregson at Lacombe,
