466 Messrs. Elwes and Edwards on 
last in size, markings, and general appearance, that I 
could not have separated; it but for the total absence of 
the sex-mark in the male, which is so conspicuous in all 
forms of nevadensis. Nepigon, a railway station on the 
Canada Pacific Railway, at the point where the Nepigon 
River runs into Lake Superior, is the only spot where it 
has hitherto been taken by Prof. Macoun, and Messrs. 
Fletcher, Scudder, and Lyman. Its habits are well de- 
scribed by Mr. Fletcher in the Annual Report of the 
Entomological Society of Ontario for 1888. It flies 
most abundantly from about June 28th to July 15th, in 
Open grassy glades surrounded by swampy forest near 
the river-bank, a mile west of the station, and also less 
commonly on a rocky ridge north-east of the railway 
bridge. 
I visited Nepigon in the hope of finding it at the end 
of July this year, on my return from the west; but, 
though the season was said to be a late one, and I 
searched both the localities carefully, I did not find a 
trace of it; so its season must be a short one. 
Mr. Fletcher states (/.c., p. 79), that a single female 
was taken by Prof. Macoun at Morley Alberta, on the 
foot-hills of the Rocky Mountains; but, in the absence 
of any confirmation of this statement, I am inclined to 
think this specimen must have been C. nevadensis, to 
which, indeed, he says it had a great resemblance. 
Judging from the few females of G/. macounii I have 
seen, I cannot distinguish between them, and though I 
am not aware that C. nevadensis has been recorded from 
the Rocky Mountains, or north of the American 
boundary, I see no reason why it should not occur 
there. The isolated existence of G!. macounii, which is 
certainly more nearly allied to nevadensis so very far to 
the east of any recorded habitat, is certainly very 
extraordinary ; but our entomological knowledge of the 
vast tract of prairie and forest north and west of Lake 
Superior is so trifling that I have little doubt but that it 
will be discovered elsewhere. 
(EZ. buddha is a species recently described by Grum- 
Grshimailo, from the mountains south-east of Koko-nor, 
on the borders of Kan-su and North-east Thibet, and, 
judging from the specimens kindly sent me by M. 
Alphéraky, is perfectly distinct from any other of the 
white-veined group, on account of the grey marginal
