"Espauds from 1-75 to 2-75 inches. All the vrings arc dull red, with the hind margins brown. 
The fore wings have two black costal marks, external to which is a large oye-likc spot composed 
of various colours, principally blue, and below this two small spots of light blue. The hind 
wings have a large blue and black eye surrounded by light brown. The underside is very 
dark brown, varied with nearly black lines. 
" Larva. Black, with minute white spots and covered with black spines. Feeds on Urtka dioica 
from June to August." {Lang, I. c.) 
Buckler gives an extended account of the early stages of Vanessa io in 
' LarvfB of British Buttci-flics,' i. p. 179. This species is not verj' common in 
Central Japan, where it is restricted to the mountains, but in Yesso and Corea 
it is plentiful. There is no difference between Japanese or Coreau specimens 
and those from Europe. Abundant in Amurland and throughout Europe, and 
also found in Asia Minor. So far as known at present V. io does not occur 
in any part of China dealt with here ; neither has it ever been recorded from 
Northern India.

bifurcated above the third median ncrvule in the fore wing, the outer portion ending in 
some small whitish spots on the costa, the band gradually increasing in width from the costa 
to the anal angle, and bearing a series of small black spots between the nervulcs (sometimes 
absent) in the hind wing ; two fine marginal blue Hues, often more or less obsolete. Fore 
wing with the costa more or less striated with bluish. Underside most beautifully variegated 
and striated with black, green, ochreous, pale violet, and ferruginous, crossed by a more or

the outer lower end of the ccU touching the median nervure, usually with two ochreous spots
