discocellular nervules slightly concave ; lower discoidal nervule from their middle ; discoidal 
cell long, somewhat narrow, extending to more than half the wing; second median nervule 
emitted about one seventh before the end of the cell, first median at nearly one half before 
the end ; submedian nervure slightly recurved.

first subcostal nervule emitted at one fourth before the end of the cell ; upper discocellular 
nervule the shorter, outwardly oblique, lower discocellular straight, erect, discoidal nervule 
from their middle ; discoidal cell rather short; second median nervule emitted from imme- 
diately before the end of the cell ; first median at one third before the end ; submedian 
and internal nervures straight. 
" Body slender, short ; ■palpi porrect, second joint pilose beneath, projecting half beyond the head ;

" Male. Ujiperside : both wings pearly white. Fore wing with the oiiter margin broadly at the 
apex, and decreasiugly towards the hinder angle dusky black, this black border being reduced 
to a very fine black line at the hinder angle ; the base, broadly along the costa and inner 
margin and within the outer black band pale clear shining blue, thus leaving a patch of the 
white ground-colour on the disc of the wing only. Hind wing with the base and abdominal 
half of the wing irrorated with very pale shining blue ; the spots of the underside showing 
through slightly on the disc ; au indistinct marginal series of dusky spots, and a fine ante- 
ciliary black line. Underside : both wings white, slightly tinted with blue. Fore wing with 
a slender blackish discocellular streak, a curved discal series of five or six elongate spots, and 
a marginal series of very indistinct small spots, obsolete at the hinder angle. Hind wing 
with ten or eleven small dusky spots, of which three are subbasal, the rest arranged irre- 
gularly across the disc ; a submarginal series of small spots, and a fine marginal black line. 
" Female. Upperside : fore wing with the costal and outer borders very broadly dusky black, the 
discal patch white, the inner margin broadly irrorated with blue. Hind wing with the discal 
area between the nervules bluish white, all the rest dusky ; a submarginal series of oval 
dusky spots, and the marginal black line. Underside : both wings exactly as in the male. 
Cilia white on both sides in both sexes. 
" Expanse, d 1-12-1-50, 2 l-3.5-l-4(:) inch." {de NiceuiUe, I. c.) 
I took specimens of this species in Satsuma dming May 1 886, and I have 
received specimens from Omei-shan, Wa-shan, and Chia-kou-ho in Western 
China, Avhich do not dift'er from Sikkim examples. There were also specimens 
in Fryer's collection fi.-om the Loochoo Islands.
