Genus Chrysophanus 



purple. On the under side the wings are marked with a multi- 

 tude of small spots and lines. The neuration of the wing is de- 

 lineated in the figure herewith given, and 

 needs no further description. 



Egg. — The eggs are hemispherical, flattened 

 on the base, the upper surface deeply pitted 

 with polygonal or somewhat circular depres- 

 sions. 



Caterpillar.— The caterpillars, so far as 

 known, are decidedly slug-shaped, thickest 

 in the middle, tapering forward and back- 

 ward, and having a very small head, 

 tion of Chrysophanus Chrysalis. — The chrysalids are small, 



thos .enlarged. Typi- r0U nded at either end, and held in place by 



cal of the genus. . .,, ,. ,,.,.,,, 



a girdle of silk a little forward of the middle. 



This genus is found in the temperate regions of both the New 

 and the Old World, and also in South Africa. 



(i) Chrysophanus arota, Boisduval, Plate XXIX, Fig. i, $ ; 

 Fig. 2, 2 (Arota). 



Butterfly.— The plate gives a good idea of the upper side of 

 the wings in both sexes. On the under side the fore wings are 

 pale gray in the male and pale red in the female, with the outer 

 margin lavender. The spots of the upper side reappear on the 

 disk. The hind wings on the under side are purplish-gray on 

 the inner two thirds and paler gray on the outer third, with 

 many black spots on the disk, margined with white. Expanse, 

 1. 1 0-1.25 inch. 



Early Stages.— These have been partially described by Dyar 

 in the "Canadian Entomologist," vol. xxiii, p. 204. The cater- 

 pillar feeds on the wild gooseberry (Ribes). 



Arota is a Californian species. 



(2) Chrysophanus virginiensis, Edwards, Plate XXVIII, Fig. 

 23, <5 ; Fig. 24, ? (The Nevada Copper). 



Butterfly.— Allied to the preceding species, but easily distin- 

 guished by the submarginal white bands of crescent-shaped 

 spots on the under side. These are particularly distinct on the 

 hind wings. Expanse, 1. 25-1. 30 inch. 



Early Stages.— Unknown. 



Virginiensis, so named because the first specimens came from 

 Virginia City, ranges in California, Nevada, and Colorado.
