ground-colour. The disc, spot of f.w. is smaller, 

 and in some specimens nearly obsolete. U.s. paler 

 as regards the green coloration of the h.w. Disc, 

 spot h.w. very small. This form seems to be inter- 

 mediate between the type and the next. Hab. 

 The mountains of Osch Turkestan, and extending 

 to the north and west (Elwes). 



b. var. stoliczkana Moore. 35 — 40 mm. <$ mucli 

 smaller than the type, paler in colour, and with a 

 distinct row of sub-marginal spots on u.s., h.w. 

 Nervures black. $ with f.w. greenish-yellow. 



C. eogene. Male. 



C. eogene. Female. 



At 



C. eogene. Var. stoliczkana. 



The disc, spot is much smaller on h.w. than in 

 typical C. eogene. 



Hab. N.E. Thibet, Lobnoor, Ladak, Sikkim. 

 great elevations— from 16,000 to 17,000 feet. 



c. var. erythias Grum. $ rather brighter than 

 type. H.w. brighter. The disc, spot larger. The 

 rnai-ginal band narrower, more obtusely angled and 

 lighter, and the spots are more numerous, besides 

 being larger and more definite. Hab. Hinducoosh, 

 Kaschmir. (R. and H.) 



d. var. elissa Grum. Smaller than type, lighter in 

 both sexes, especially as regards the h.w. The 

 yellow marginal spots are more distinct in ? , and 

 have a tendency to coalesce. Disc, spot of h.w. 

 disproportionately developed. Neuration of u.s. 



h.w. of a greenish colour ; darker than that of the 

 ground-colour. Hab. Northern Pamir. (R. and H.) 



e. ab. cana Gr.-Gr. The white form of <j> . 

 Hab. Cashmere. 



/. var. arida Alph. $ has the marginal ban* I - 

 narrower than in type. Ground-colour orange, 



s ewhat lighter. $ white, like C. diva $, or 



blackish, with yellowish-green spots. Disc, spot 

 h.w. orange or red. Very variable. Hab. Koko- 

 noor and Lob-noor districts. This is probably only 

 a local form of C. eogene, peculiar to the arid 

 deserts of the above-mentioned localities. There 

 is a fine series of this form in the collection of 

 the late Mr. H. J. Leech, from which the above 

 note was made.

 p. 35, pi. xiv. 4 (1883). 



43 — 51 mm. 



Rather larger than C. eogene, not so deeply 

 coloured. Borders narrower. Disc, spot f.w. long 

 and narrow. Fringe of ou. marg. more distinctly 

 red. U.s. f.w. greenish, except along inner margin, 

 which is orange mixed with grey. H.w. greenish, 

 disc, spot small and pink. 



Hab. Kuldja. At higher altitudes than C. thisoa. 

 7,000—12,000 feet. Flight very swift, like that 

 of C. eogene. 



16. C. viluiensis Men. Schrk., p. 18, T.I. 7. 

 45 — 50 mm. 



$ ground colour orange, but paler than in the 

 preceding species, and with less reddish tinge. 



1 . viluiensis. Male. 



F.w., border much as in C. thisoa, but w 

 slight trace of yellow veining near apex, 

 much as in that species. H.w. with a
