A rather uncommon species in the Province.. I have it from Fitzgerald (Carter) and Fraser 
Mills (Marmont), and have seen a specimen from Kaslo (Cockle). The species occurs in 
Manitoba and Ontario. The types of exrclamationis came from the Siskiyou Mountains, North 
California, and the types of colorandensis were taken in Colorado. Barnes and Lindsey, who 
have examined the types, consider them conspecific. The early stages are unknown. 
Genus ADAINA Tutt. 
Adaina Tutt, Ent. Rec., XVII., 37, 1905. Ocelli obsolete. Palpi moderate, ascending, slender. 
Primaries cleft from two-thirds or before. Secondaries trifid, third feather without black scales 
in fringes. Very close to Oidamatophorus, but differs chiefly in venation of primaries, as a 
reference to the figures on Plate V. will show. ‘The cleft in primaries is also cut more deeply, 
thus making the lobes longer in proportion. ; 
1. ADAINA MONTANA Wals. form prctivis Meyrick, Exot. Microlep., I., 112, 1913. Primaries 
cleft to three-fifths, lobes rather narrow, equal, pointed; white, sometimes mixed with light- 
brownish suffusion; basal half with a few scattered, dark fuscous scales; a moderate oblique 
fascia of dark fuscous irroration from costa beyond base of cleft to middle of inner margin. Both 
lobes more or less sprinkled with dark fuscous. Fringes white on inner margins of both lobes, 
brownish towards apices. Secondaries rather dark grey with fringes paler. Expanse 16 min. 
Thorax white, posterior half sometimes light brownish, abdomen white, sometimes with faint 
brownish dorsal lines. (The British Columbia example has the posterior half of the thorax 
and the abdomen a light ochreous. ) 
One specimen in fair condition taken by Mr. W. B. Anderson at Fort Fraser on September 
16th, 1921. 
The species was described from two specimens taken at Toronto, Ont., in August. It also 
oecurs in Manitoba. It has been reared in Colorado by Dyar and Caudell in the heads of 
Helianthus pumilus. 
Genus OIDAEMATOPHORUS Wallengren. 
Oidematophorus Wallengren, Skand. F-jiid., 19, 1859. 
Pterophorus Wallengren (not Geoff.), ibidem, 20, 1859. 
Front rarely with tuft. Ocelli obsolete. Palpi short to long, usually slender, and more or 
less oblique. Tibia with or without conspicuous scale-tufts. Primaries cleft two-fifths or less. 
Secondaries trifid, fringes without black scales. 
Writing of this genus, Barnes and Lindsey state, in part, that “The species of Oid@mato- 
phorus are not at all difficult to identify when one has gained some familiarity with them. 
Usually some one or two characters suffice, but we have found that very nearly all characters 
of colour and pattern are subject to such variation that the construction of a key is very difficult.” 
As there are sixty species of this genus in North America, many of which are closely allied, 
the authors prepared a key conibining structural characters together with those of coloration and 
maculation. A number of species were inserted under two categories so as to make use of the 
most salient features. 
As only eleven of these species occur in the Province, I have constructed a key based (with 
the exception of monodactylus Linn.) on the colour and pattern of the wings alone, which I think 
will suflice for the identification of most of our British Columbia species of this genus.
