in the male. UNDERSIDE, doth wings variable in tone of colour, being much darker in some 
specimens (including the type specimen figured) than in others, the discal markings sometimes 
blurred and running into the pale margin beyond, otherwise much as in the male.” 
“ Closely allied to Polyommatus ellist, Marshall, but the male differing from the type speci- 
men of that species in having the apex and the outer margin of the forewing more rounded ; in 
P. ellisi the apex is acute, and the outer margin straight ; the upperside of both wings paler in 
colour and more broadly irrorated with greenish scales, the discal spots more numerous; the 
markings on the underside throughout more prominent, and with an additional spot in the cell 
of the forewing. The colouring of the figure of P. e/isi is much too vivid, the metallic colouring 
of the base of the wings and the body is a very pale green.” 
“ Tycena wosnesenskit, Ménétriés (Cat. Mus. Petr., Lep., vol. i, pp. 58, 95, n. 964, pl. iv, 
fig. 6, 1855), is also a closely allied species, the upperside being figured with the apex of the 
forewing very acute, the figure of the underside shewing it quite rounded, It is recorded from 
Kamtchatka,” 
“ This species (Z. Jeela) was found by me only on passes ; the female figured was taken 
near the top of the Zoji-la on the Ladak side at about 11,000 feet elevation on June 27th, 1879 ; 
on July 2nd seven specimens of both sexes on the Mamyika Pass, Ladak, 13,000 feet ; and, 
lastly, on July 3rd, seven more specimens on the Fotu-la, Ladak, at about the same elevation.” 
(de Nicéville, \. c.) 
The three preceding species are decidedly very closely allied, and are perhaps at best 
geographical varieties or local races only ; hereafter, if larger series be collected from Ladak, 
Kashmir, Chumba, and intermediate tracts, it may be found that these forms are completely con- 
nected by intermediate gradations, and thus compose but one rather variable species. In the 
meantime they are recorded as distinct species—Z. jaloka from Kashmir, Z, e//isi from Pangi, 
and L. /eela from Ladak.

“FOREWING, elongated, triangular in the female; costal mnervure extending to nearly 
half length of the margin ; first subcostal nervule free from costal nervure but running along its 
end, emitted beyond one-half before the end of the cell, second subcostal at one-third, ¢hird 
subcostal at one-sixth, fourth subcostal at one-half from third, and terminating before the 
apex ; fifth subcostal [upper discoidal] from the end of the cell; disco-ce//ular nervules slightly 
oblique, nearly straight ; radia/ [ lower discoidal] nervule from their middle ; discoidal cell long, 
extending to more than half the wing ; second median nervule emitted at one-sixth before the end 
of the cell ; st median beyond one-half before the end ; sudmecian nervure straight. HINDWING, 
oval ; exterior margin very convex ; no tail ; costal mervure arched at base, extending to apex ; 
first subcostal nervule emitted at one-third before the end of the cell; upper disco-cellular 
nervule oblique, Jower disco-cellular erect ; radial nervule from their middle; discoidal cell 
short, broad ; ¢hirdand second median mervules emitted from the end of the cell, fst median 
at one-half before the end ; sabmedian and internal nervures straight. Bopy small, short ; palpi 
slender, porrect, second joint long, projecting two-thirds beyond the head, attenuated at its tip, 
clothed with long adpressed scales, third joint very long, naked ; /egs slender; antenne 
with a stout grooved club. Type, C. /aius, Cramer.” (A/oore, |. c.) 
The neuration of the forewing I should describe as follows: Costal nervure terminat- 
ing just before the apex of the discoidal cell, slightly bent downwards or bowed just before 
its termination ; first subcostal nervure bent upwards to meet that portion of the costal neryure 
which is bent downwards ; second subcostal with its base a little nearer to the base of the first 
subcostal than to the base of the upper discoidal ; third subcostal emitted from the subcostal 
nervure nearer the apex of the cell than of the wing; upper disco-cellular nervule wanting ; 
middle disco-cellular emitted from the upper discoidal some little distance beyond its base. In 
the hindwing the second median nervule is emitted just before the lower end of the cell, The
