134 THE BUTTERFLIES OF THE WEST COAST 



121. Argynnis Hydaspe. Never before illustrated.

 Hydaspe is a variety of Zerene, in which the underside is obso- 

 lescent as to the buff spots, and the whole wing is suffused with a 

 cinnamon color, as is well shown by the Plate. Both sexes afford 

 this variety, which is found wherever Zerene may be common. 

 The spots are never silvered in this variety. 



122. Argynnis Monticola.

 Monticola is a common Argynnid of Northern California, being 

 abundant everywhere in the mountains, and it also extends in 

 more limited numbers through Oregon, Washington, Idaho and 

 British Columbia. On upper side it looks similar to Zerene, but 

 on the underside it is pinkish in color of the hind wing, the spots 

 being straw-colored in the male, and usually silvered more or less 

 in the female. 



123. Argynnis Purpurascens. 



Plate XIV ; Figures 123, b. Females both, Sisson, 189T ;

 This is a variety of the preceding, the female only being the 

 subject of the variation. This variation manifests itself in an 

 exuberance of size, and of color, both on the upper and on the 

 underside, the underside being suffused with a purplish tint on the 

 underside of hind wing. The large purple specimens are es- 

 pecially splendid when fresh, but the purple tint soon fades. 



124. Argynnis Rhodophe. 



Plate XIV ; Figures 124, a. Males, Vancouver Island, 

 July, 1892 ; Author. 

 A very dark species, allied, apparently, with Bremneri, and 

 found in the same latitude, but more in the interior, and on the 

 mountains, while Bremneri is on the plains, and near the coast. 

 The dark spots on upper side are very black and large, and those 

 of the median band are all connected together. On the underside 

 the disk or center of the hind wing is very dark, like Bremneri,
