THE CANADIAN ENTOMOLOGIST. 33 



Female. — Expands 1.5 lucli. 



Similar 10 the male, the basiil meas black, but the .spots still more 

 difiused. 



Under side a> in the niak-, Init there is a little more yello\s at apc.x, and 

 in the interspaces along hind margin are streaks ui yellow. Secondaries 

 intense red from base nearly to the roiuided spots, and the edge there is 

 fringed with elear \vhite scales next costa, and white mixed with bluish or 

 slate-colored on posterior half; these dark scales edge the nervules nearly 

 to margin ; the extra-discal area is same red, but over a yellow ground, the 

 yellow no where distinctly appearing ; the round spots and the submar- 

 ginal lunules same red as the base ; the silvery line as in male. 



From I $ taken at Cape Thompson, North-west America, July 19, 

 1 88 1, and i $ taken at Kotzebue Soiuid, July 14th, 1881, by JVIr. E. W. 

 Nelson, of the U. S. Signal Service. 



These examples differing markedl} from any Argynnis in my collec- 

 tion, I sent the male to Mr. A. G. Butler for determination. Mr. Butler 

 replied : "It differs from Char idea in the redder coloration, and much 

 heavier markings on the tipper surface ; the basal area is blacker, the spots 

 and stripes much thicker. Below, the markings are altogether darker than 

 in Chariclea of Etirope. \'our example agrees perfectly with a specimen 

 (in Br. Mus. Col.), labelled Nova Zembla, and with two of the Grinnell 

 Land series, included under Mr. McLachlan's varieties of Chariclea. It 

 is in my opinion worthy of a distinct name." 



I take pleasure in naming the species after Mr. Butler. 



Argynnls Eurynome Edw. 



Var. Erinna. 



Upper side in both sexes like the type form : un under side secondaries 

 much covered with dark ferruginotis, and sometimes even the belt between 

 the outer rows of silver spots is more or less densely covered with same. 

 In one % , except for a paler shade in the interspaces (but still ferrugin- 

 ous) on the area of this belt, the entire wing would be solid ferruginous. 

 very little mottled with yellow btiff on basal part of the disk. One male 

 is nearly as dark. Others, of })oth sexes, art more or less mottled with 

 yellow buff, and the belt is of that color, clear. There is an absence of 

 green (olive) in all examples under view. If it were not that among 

 these are some exactly like examples from Colorado. with(nu green, I 

 should consider the present as a distinct species. 1 ha\c 12 j" , 4 ^ from
