submarginal and marginal stripes: primaries of the female 
with a large oval bipupillated ocellus towards the apex, the 
male rarely showing a trace of a similar ocellus, but usually 
entirely destitute of it: secondaries with a large circular uni- 
pupillated ocellus on the first median interspace, and fre- 
quently, in the male, one or even two minute subanal ocelli in 
an oblique line with the large ocellus: primaries of the male 
with a blackish nebula over the median area. Under surface 
sordid white, the primaries and base of secondaries more or 
less suffused with brown, and the entire surface of all the 
wings densely covered with numerous sharply defined darker 
brown strie; marginal and submarginal stripes as above: 
primaries in both sexes with a well-defined bipupillated black 
subapical ocellus with pale yellow iris ; a dark brown stripe from 
just beyond the middle of the costa across the disk to the ter- 
mination of the submarginal stripe: secondaries crossed 
beyond the middle by an irregularly angulated stripe, some- 
times barely traceable, but usually well defined; three well- 
defined ocelli, one apical and two subanal, the last being 
smaller than the others and bipupillated. Expanse of wings 
37-42 millim. 
Seven examples, N. Formosa. 
The specimens of this species are for the most part more or 
less shattered, as though they had been long on the wing.

Pontia niobe, Wallace, P. Z. 8. 1866, p. 357. n. 6. 
N. Formosa. 
One example has the apical spot better developed than 
usual, so that it looks like a pale specimen of P. xiphia.

The external border of the secondaries appears to vary in 
width, as in the two males now received it is as wide as in
