CAMENA. 



351 



primaries whitish grey ; discoidal spot liocar, white ; central transverse line hlaukish, termi- 

 nating at the submedian ncrvurc ; suhmarginal line indistinct ; on the middle of inner margin 

 is a fan-like arrangement of long dark grey hairs ; central transverse line of secondaries wavy, 

 turning ofl" at a right angle to abdominal margin when o])positc anal angle ; outer margin 

 bordered with dark grey, intersected by a band of ground-colour ; a large black si)ot 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, J 38 millim., 5 40-42 millim. 



One female example 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, Naini-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 in 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.

Camena ctesia, Hewitson^ 111. Diurn. Lep. p. 48, pi. xx. figs. 1, 2, (J (1865) ; Elwes, 

 Trans. Ent. Soc. Lond. 1888, p. 394, pi. viii. fig. 6; de Niceville, Butt. Ind. iii. 

 p. 340, pi. xxviii. fig. 215, (1890). 



" Upperside. Male. Brilliant ultramarine blue, marked by a triangular dark brown spot ; all the 

 margins broadly dark brown. Posterior wing with the apex 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, eajh with a band of 

 brown (scarcely visible on the anterior wing) near the outer margin. Posterior wing with a 

 suhmarginal band of brown spots, the two apical spots crowned with orange. Expanse 

 ly^ij inch." (Hewitson, 1. e.) 



" Female. Upperside : fore wing differs from the male in the absence of the two black spots, other- 

 wise as in the male." (de IficetnUe, 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.
