M 40 British Columbia. 192: 



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 exclamatianis came from the Siskiyou Mountains, North 

 California, and the types of colorandetlsis were taken in Colorado. Barnes and Lindsey. who 

 have examined the types, consider them conspecific. The early stages are unknown. 



Genus ADAINA Tutt. 



Ada ina Tutt, Ent. Rec, XVII., 37, 1005. Ocelli obsolete. Palpi moderate, ascending, slender. 

 Primaries cleft from two-thirds or before. Secondaries trifld, third feather without black scales 

 in fringes. Very close to Oidainatophnrus, 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 jiontana Wals. form DECovis Meyrick, Exot. Mierolep., 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 mm. 

 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, 1021. 



The species was described from two specimens taken at Toronto. Out., in August. It also 

 occurs in Manitoba. It has been reared in Colorado by Dyar and Caudell in the heads of 

 HeliantJius pumilus. 



Genus OIDAEMATOPHORUS Wallengren. 



Oidmmatophorus Wallengren, Skand. F-jiid., 19, 1S59. 



Pteropliorus Wallengren (not Geoff.), ibidem, 20, 1S59. 



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/rmato- 

 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 combining 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 monodactylilS Linn.) on the colour and pattern of the wings alone, which I think 

 will suffice for the identification of most of our British Columbia species of this genus.
