Genus Chrysophanus 
(3) Chrysophanus xanthoides, Boisduval, Plate XXVIII, 
Fig. 29, 6 ; Fig. 30, ? (The Great Copper). 
Butterfly.—The student will easily recognize it by its larger 
size, it being the largest species of the genus in North America, 
and by its creamy-white under surface, spotted with distinct 
small black spots, in large part reproducing the spots of the 
upper side. Expanse, 1.50-1.65 inch. 
(4) Chrysophanus editha, Mead, Plate XXVIII, Fig. 26, 6 ; 
Fig. 27, ? (Editha). 
Butterfly.— This is a much smaller species than the last, which 
it somewhat resembles on the upper side. On the under side 
it is wholly unlike xanthoides , the wings being pale pearly-gray, 
pale ochreous on the outer margins, the spots of the fore wings 
black and of the hind wings ochreous, narrowly margined with 
white or fine black lines. Expanse, 1.10-1.25 inch. 
Early Stages.— Entirely unknown. 
This species is found in Nevada. 
(5) Chrysophanus gorgon, Boisduval, Plate XXVIII, Fig. 35, 
6 ; Fig. 36, ? (Gorgon). 
Butterfly.— Somewhat like the preceding species, but with 
the fore wings of the male redder on the upper side, and of the 
female more broadly mottled with pale red, the spots in some 
specimens inclining to buff. The under side of the wings is 
white, marked with the usual series of black spots. The sec¬ 
ondaries have a marginal series of elongated pale-red spots, 
tipped at either end with black. Expanse, 1.25-1.30 inch. 
Early Stages.—We as yet know nothing of these. 
Gorgon is found in California and Nevada. 
(6) Chrysophanus thoe, Boisduval, Plate XXVIII, Fig. 31, 
$ ; Fig. 32, $ ; Plate V, Fig. 50, chrysalis (The Bronze Copper). 
Butterfly.—The plate makes a description of the upper side 
of the wings unnecessary. On the under side the fore wing in 
both sexes is bright tawny-red, pale gray at the apex; the hind 
wings are bluish-gray, with a broad band of carmine on the 
outer margin. Both wings are profusely adorned with small 
black spots. Expanse, 1.30-1.40 inch. 
Early Stages.— These are only partially known. The cater¬ 
pillar feeds on Rum ex. 
It is not uncommon in northern Indiana, Illinois, and Pennsyl¬ 
vania, and ranges from Maine to Kansas and Colorado.
