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. 
Chrysalis. — The chrysalids are small, 
rounded at either end, and held in place by 
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. 
(1) Chrysophanus arota, Boisduval, Plate XXIX, Fig. I, $ ; 
Fig. 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, 
1.10-1.25 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, $ ; 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.
