CAMEXA. 351 
primaries 'whitisli grey ; discoidal spot linear, white ; central transverse line blackish, termi- 
nating at the submedian ncrvure ; submarginal line indistinct ; on the middle of inner margin 
is a fan-like arrangement of long dark grej' hairs ; central transverse line of secondaries wavy, 
turning off at a right angle to abdominal margin when opposite anal angle ; outer margin 
bordered with dark grey, intersected by a band of ground-colour ; a large black spot on the 
outer edge of a round orange patch before the first tail, and one at angle preceded by an 
orange streak. 
Female. Greyish black, with a patch of pale lilac-blue on the disc of primaries, and some scales of 
the same colour towards outer margin of secondaries ; fringes grey. On the under surface 
the lines are more distinct and the spots larger. In one female specimen the lilac-blue is 
only shown on the primaries as a discal suffusion. 
Expanse, c^ 38 millim., 2 40-42 millim. 
One female exam^ile from Omei-shan is without blue on upper surface of 
primaries, and there are no transverse wavy lines on the under surface. 
This insect appears to be widely distributed throughout the Himalayas, but 
nowhere common ; de Niceville records it from Chumba,Kulu, Simla (6000 feet), 
Masuri, Naiui-tal, and Darjiling. It is on the wing in May and August. 
Occurs in Western China at Omei-shan in June, and Chia-ting-fu iu July, 
and at Chang-yang, Central China, in July and August. 
Since describing this species under the name of contractus, I have received 
a large number of specimens, and now find that, although variable, my insect 
cannot be specifically separated from C. icetas, Hewitson.

" Upperside. Male. Brilliant ultramarine blue, marked by a triangular dark brown spot : all the 
margins broadly dark brown. Posterior wing with the apes dark brown ; an apical brown 
spot irrorated with white. 
" Underside. Glossy grey. Both wings with a brown spot at the end of the cell, each crossed 
beyond the middle by a band of dark brown spots bordered with white, ea-h with a band of 
brown (scarcely visible on the anterior wing) near the outer margin. Posterior wing with a 
submarginal band of brown spots, the two apical spots crowned with orange. E.xpanse 
l-j-^j inch.*' {Hewitson, I. c.) 
" Female. Tpperside : fore wing differs from the male in the absence of the two black spots, other- 
wise as in the male." (de JS'idville, I. c.). 
I have one male specimen from Chia-kou-ho, Western China, taken in 
July at a low elevation. This example differs from Indian specimens in 
having less blue on upper surface and a larger discal spot on primaries; the 
under surface is browner.
