•'Most nearly allied to N. alumpra, from Assam, and (juito different from X etiri/iiomc ; may be 
distinguished by the alisence on both the upijcr and underside of the hind wing of the narrow 
submarginal white lunular line." (Moore, I. c.) 
Sangaica appears to be the spring form of i\'. eurijnome, and differs from 
the type-form chiefly in its general smaller size and in the narrower bands on 
the under surface of secondaries ; the whitish submarginal band is usually 
absent, and the whitish line between the bands is often eliminated. My 
specimens vary from 54-62 millira. in expanse. I have only received this 
form from Central and Eastern China, where it seems to be common. 
"N . eurynome can be separated from all its other Chinese allies by the 
distinct black edging to the white markings of the under surface and the 
more yellowish ground-colour. It varies considerably in the width of the 
bands and size of the spots, and ranges in expanse from 64-75 millim. 
iV. varmona and several other Indian Neptis are probably only forms ol 
N. eurynome. 
Occurs abundantly throughout China, from Niugpo to Moupin.

Var. intermedia, W. B. Pryer. (Plate XIX. fig. S.) " Tliorax iridescent green, upperside, 
ground-colour brown-black. Fore wing, in costal half a longitudinal white streak from base 
two thirds across the wing, interrnpted towards the end by a band of the ground-colour ; in 
outer half six large white spots form a sort of bow-shaped band across the wing, bending 
inwards towards the inner margin ; a submarginal line of irregularly-shaped white spots : 
hind wing, a transverse straight white band from inner half of abdominal margin to outer 
half of costa; from just above anal angle a thinner white band or streak, interrupted by the 
ground-coloured nervures, crosses the wing nearly to the anterior angle. Underside dark 
chocolate, shading into lead-colour on inner margin of fore wing, markings much the 
same as on upperside, the submarginal rows of spots on fore wing being more distinctly 
marked, and there are generally some additional wliitc marks on the margin itself; hind 
wing, in adcilion to the upperside markings, there is a thin submarginal white line, a some- 
what indistinct white line between the two central bands, and from the base there are two
