THE CANADIAN ENTOMOLOGIST. 153 



But I have found nothing amongst north-western material examined that I 

 can treat as distinct under the name Edwardsit, by which the form 

 generally passes, and as which it was probably recorded from Alberta by 

 Geddes. Ntvadensis is smaller, though about right in colour, and is more 

 lightly shaded basally, with the veins less black, and the green paler. 

 Colorado Meadii, as to basal shading and black, is even a little too dark. 

 The shape of the silver spots agrees with the local form, though the green 

 encroaches more on the buff band, differing in this respect from 

 Nevadeiisis. The Calgary species, however, differs rather markedly from 

 eitlier Nevadensis or true Meadii in the tint of the green, this being, 

 especially in the female, ahnost a peacock blue. An exception must be 

 made with the Stockton, Utah, pair, which approximate the local form so 

 much more nearly than any of the rest, that I have at times rather doubted 

 the genuineness of the labels. 



17. A. Alberta^ Edw. — Mrs. Nicholl and I met with the species in 

 fine condition on several mountains near Laggan, far above the timber 

 line, from July 19th onwards, in 1904. The lower spurs and shoulders of 

 Mts. Fairview and Piran are easily accessible to an energetic amateur 

 hill-climber (I may remark that the " hills " are a bit steep !), and good 

 hunting grounds for this species. The ridge leading from Fairview to the 

 Cattle Crags holds the species, and is partly smooth, even ground, but 

 dangerously precipitous on the Lake Louise side. It is best reached via 

 the trail right up to Saddle-Back, and thence over nearly the summit of 

 Fairview. A long low spur of ]Mt. Piran, on the side next Mts. White 

 and Victoria, is also an excellent hunting ground, easy to run on, and not 

 a bit dangerous. The insect is far easier to capture than astarte, and, 

 unlike that species, the sexes were taken in about equal numbers. It 

 usually flies close to the ground, frequently settles, and when approached 

 does not rise quickly nor high. Mrs. Nicholl subsequently found it 

 widely distributed between Laggan and Field. Bean records the capture 

 of a pair on a mountain near Hector, B. C. (Edwards Butt. N. Am., Vol. 

 Ill), and Mrs. Nicholl captured specimens on a mountain rising from the 

 lower end of Wapta Lake at Hector, near Lake O'Hara, and at the 

 very head of the Yoho Valley, the latter at about 8,000 feet. She also 

 met with it in abundance during the latter part of July of last year (1907), 

 on a trip from Laggan to the head waters of the Athabasca. She writes : 

 ''Alberta fairly swarmed in places. I got twenty-five in one day on the
