wings 2 J to 2| inches." (IF. B. Prijer, I. c.) 
This eastern form of N. aceris varies greatly in size and in the width of 
the Avhite markings ; none of the specimens, however, have quite so much 
Avhite as typical N. aceris, and the ground-colour of the under surface is 
always darker. 
Occurs commonly throughout China, Japan, and Corea during the warmer 
months of the year, also found in Amurland.

" Sexes alike. Allied to N. nandina, but differs on the underside in having the discoidal streak 
narrower, and the seven spots of the curved row are much smaller, being onlj^ half the size, 
and are wider apart ; the submarginal row of spots is also smaller ; the bands on the hind 
wing are also narrower. Underside deep maroon, the marks as on upperside, but those on 
hind wing less straight." (Aloore, I. c.) 
" All the markings in this species are very small and narrow, and more or less sullied, not clear 
pure white, the submarginal series of small white spots on the upperside of the fore wing 
complete. On the underside the markings are pure white, and of nearly equal width 
throughout. It appears to be a constant and well-marked species." {cle Niceville, I. c.) 
My Chinese specimens of N. soma agree with Mr. Moore's type, but differ 
from Mr. de Niceville's figure as follows : — The band of secondaries widens 
out towards costa, and the outer broad band is straight and terminates nearer 
to the anal angle. One specimen from Ta-cliien-lu has the Avhite bands of 
all the wings much broader, and seems to agree with N. yerhurii, Butler, of 
which species I have an extensive series from the North-west Himalayas. 
Occurs commonly at Wa-shan, Ta-chien-lu, Omei-shan, Pu-tsu-fong, and 
Chia-kou-ho, in Western China. It is found in June and July at various 
elevations up to about 'JOOU feet.
