39. Chionobas Macounii, Edw. — During June (2 2nd-24tb), 1905, 

 Mr. Hudson and I came across the true habitat of this species. About 

 ten or twelve miles west of here, in the " Billings's Mill " locality, is where 

 we had occasionally taken a few specimens in previous years, flying near 

 the foot of the spruce-covered hills. Most of the hills are heavily timbered 

 on the north slopes, the spruce timber merging into poplar scrub at the 

 surnmit, and the southern slopes are grass-covered and void of timber. 

 Amongst the poplar scrub, and at the edge of the spruce, is where we 

 found both sexes quite fresh, the males comparatively common, on the 

 above dates. The light colour of the upper side makes it a more con- 

 spicuous object \\-\2iX\ jutta when on the wing, and though, perhaps, just as 

 shy of approach, its flight is rather slower, and it usually settles on fallen 

 timber instead of high in standing trees like that species. The difficult 

 nature of the ground prevented our taking more than we did. Some males 

 show a decided tendency to develop a sex-mark, thus showing a closer 

 relationship to ^/jg't?^ than was previously supposed. Jutta was common 

 at the same time, in amongst the timber, and usually at the foot of the 

 hills, where Macounii was far less often seen. 



41. C. Alberta, Elwes. — For "below the cell," in line 12, read 

 " opposite the cell." The species has been very scajce of recent years. 



42. C. vanina, Edw. — Mrs. NichoU found this species common on 

 the Kootenai Plains, near the head of the Saskatchewan, in mid-July. 



44. C, Eeatiii, Elwes, = subhyalina, Edw. — Mrs. NichoU and I 

 found this common on the only three peaks we visited near Lake Louise, 

 Laggan, on July 19th and 20th, 1904. These are Mts. Piran, Fairview 

 and Saddle Peak. (For altitudes vide under astarte.) We saw it then 

 only on or very near the extreme summits, though Mr. Bean wiites in 

 Edw. Butt. N. Am., IH : " Its observed range of altitude extends from 

 7,300 ft., for occasional stragglers, timber-line at Laggan being 7,000 ft., 

 to 8,500 ft., as the males habitually frequent rock wastes at the points and 

 ridges of the peaks. The females seldom reach such localities, but chiefly 

 inhabit sedgy slopes in a belt of altitude between 7,500 and 7,800 ft." 

 We met with but few females, but one from Fairview on 19th is labelled 

 "Near summit; over 8,500 ft." Mrs. NichoU found it common on aU
