Genus Argynnis 



of the outer line usually found in other species of the genus. The 

 dark markings of the outer margin are almost entirely absent, and 

 those of the discal and basal areas very greatly reduced. On the 

 under side both wings are very pale, the spots entirely without 

 silver, in some specimens even their location being but faintly in- 

 dicated. The fore wings at the base and on the inner margin are 

 laved with bright red. 



$ . The female resembles the male, except that the red on the 

 under side of the fore wings is in many specimens very bright and 

 fiery. Expanse, $ , 2.50 inches; ?, 2.75-3.00 inches. 



Early Stages. Entirely unknown. 



This butterfly, which is still rare in collections, has been taken 

 in southern California. It may be an extreme variation of the next 

 species, A. adiante, Boisduval. 



(40) Argynnis adiante, Boisduval, Plate XIV, Fig. 4, ? (Adi- 

 ante). 



Butterfly, $ . The wings on the upper side are bright fulvous ; 

 the black markings are slight The fore wings on the under side 

 are pale buff, much lighter at the apex, laved with orange-red at 

 the base. The hind wings are pale buff, clouded with fawn-color on 

 the basal and discal areas. All the spots which are generally silvered 

 in other species are in this species wholly devoid of silvery scales. 



$ . The female is like the male, but the black markings on 

 the upper side are heavier, and the basal area and inner half of 

 the primaries are laved with brighter and deeper red. Expanse, 

 $ , 2.30-2.40 inches; ?, 2.30-2.60 inches. 



Early Stages. Unknown. 



This species is found in southern California, and is somewhat 

 local in its habits, hitherto having been taken only in the Santa 

 Cruz Mountains. 



(41) Argynnis artonis, Edwards, Plate XII, Fig. 13, $ , under 

 side (Artonis). 



Butterfly, $ . Closely resembling A. eurynome, Edwards, 

 from which species it may be at once distinguished by the en- 

 tire absence of silvery scales upon the under side of the wings, 

 and also by the fact that the silver spots on the under side of 

 the hind wings are not compressed and elongated as much as 

 in eurynome, and by the further fact that all the dark marginal 

 markings of the under side are obliterated. 



? . The female does not differ materially from the male, except
