foUo^ved by a series of small white spots on the outer margin wLieh arc confluent with the 
white dashes in the black fringes. 
Soxes alike, but the tawny marks on upiicrside of female are rallier larger. 
Expanse, d' 32 millim., J ;i3 niillim. 
An example of each sex taken at an elevation of 10,000 feet in July by a 
native collector at Pu-tsu-fong and three males from the high plateau to the 
north of Ta-chien-lu. These last ditfer from tlie type, as described above, in 
being smaller and ratlicr darker on the upper surface.

" Allied to u4ti«acrt, aspect of iAy;»j)7i (>//(()». AVings with outer margin broad, costal uervure of 
fore wing terminating abruptly at about the middle of the costa, opposite to the end of the 
discoidal cell ; subcostal ncrvure with five branches, the last two forking to apex ; upper 
radial nervule emitted from the inferior margin of the subcostal near its origin * ; lower 
radial equally dividing the discocellulars, which arc concave ; second and third median nervules 
emitted uear together ; ju-iccostal ncrvure of hind wing short, oblique, directed backwards ; 
costal nervure short, straight, oblique, terminating at basal third of costa ; subcostal nervuro 
forking beyond the end of cell, the upper fork running close to the margin from the second 
third of costa ; radial nervule emitted close to the subcostal, reducing the upper discocellular 
nervule to a point ; lower discociilular long, oblique, nearly straight ; second and third 
median nervulcs emitted nearer together than the first and second. Body slender ; eyes 
prominent ; antenna; slender, submonilLform ; palpi very small.

" This diagnosis is evidently drawn up from a female specimen, though the sex is not stated. In 
the male the inner and outer margins of the fore wing are exactly equal in length, the latter 
is nearly straight, not strongly convex as in the female, and the apex very acute, not rounded. 
It has no secondary sexual characters. The hind wing is much less broad than in the female."

"Both wings semi-transparent, snow-white. Fore wing with broad costal and external dark 
brown borders, sinuated internally ; tn'o irregular subraarginal series of unequal white spots. 
Hind wing with a broad dark brown outer border, undulated internally; a sinuated disco- 
submarginal lunulated palo brown line ; a submarginal series of elongated white spots. Body 
* " This is surely a mistake ; the subcostal ncrvure originates from the bas of the wing, the 
upper radial nervule has a common origin with the middle discocellular nervule (the upper disco- 
cellular is wanting in this genus) from a point on the subcostal nervuro beyond the base of the 
second subcostal nervule." (dc ^'icvville, 1. c.)
