460 PAPILIOXID^. 
" Femide. Base of -wings, nervures, and exterior margin of hind wing suffused with greenish grey. 
Fore wing with the discoidal, black, transversely quadrate spot large, the black marginal and 
submarginal band broad, the interspaces forming a series of white outwardly pointed spots. 
Hind wing with a similar submarginal, apically black, zigzag band, the intermarginal space 
forming a series of white inwardly pointed spots. 
"Expanse, d li inch, 5 ]| inch." {Moore, I. c.) 
My collectors did not meet vni\\ this insect in any part of China that they 
visited, but M. Potanine obtained specimens in April at Sinine, Province of 
Kansou. In referring to these specimens, Alplieraky says that they are inter- 
mediate between his var. orientalis * from Kuldja and chrysidice, Herr.-SchafF. 
" The female is smaller, but does not otherwise differ from orientalis ; but 
the male is at once distinguished by its more slender form and the absence of 
the black spot above first nervure of primaries . Probably it is identical with 
Jcalora, Moore, at least the figm-e of male kalora is exactly like the male 
from Sinine, and both .approach var. chrysidice from Asia Minor." 
Var. kalora, Moore, is one of the commonest of the Pieriuae met with 
between 10,000 and 16,000 feet in the North-west Himalayas. It differs only 
from typical S. callidice in the darker green coloration of the under smface 
and in the female being somewhat more suffused with darker scales on the 
upper surface. The size of the black spot at the termination of the cell is a 
variable character both among European and Indian examples, and so also 
are the dark apical markings of the male. 
I received male specimens from M. Grum-Grshimailo labelled Pieris chry- 
sidice, var. kalora, from Amdo. They differ from aU my North-west 
Himalayan examples in having a larger and more quadrate black spot at end 
of the cell distinctly bisected with white, and in having one or sometimes two 
additional spots in the submarginal series of primaries towards inner margin. 
On the under surface the brownish-green markings of secondaries are much 
reduced in size, and the interstices are pure white. 
Genus METAPORTA. 
Metaporia, Butler, Cist. Entom. i. p. 51 (1870). 
" Fore wings subpyriform : second subcostal not so near end of cell as in Aporia ; upper 
discocellular oblique, nearly as long as lower, which is perpendicular and feebly arched ; 
second and third median branches rather near together."
