fore wing, which seems more or less characteristic of 

 TJiisoaand Meadii. On the under side it resembles Thisoa, 

 but has the veins distinctly yellowish, and the central 

 white spot more surrounded with red. 



It occurs on the Baralacha Pass, the Zogi-lah Pass, 

 and other of the alpine passes which lead from the 

 Himalayas into the dry climate of Ladak, from 11,000 

 feet upwards ; and if I am right in uniting with it the 

 form named TJieia by Staudinger in his MS. Catalogue 

 of 1882, which was collected by Haberhauer in the 

 mountains near Osch, in Eastern Turkestan, extends 

 considerably to the north and west. 



The specimens from Osch, however, of which two 

 are before me, are not nearly so brilliant or distinct 

 in colour as those from the Himalayas ; and appear to 

 be a transition to the form named Stoliczkana, of which 

 I have seen two specimens collected by Stoliczka himself, 

 and which, though much smaller, paler in colour, and 

 distinctly spotted on the under side, might be only a form 

 of Eogene. As, however, no females of this supposed 

 species are known, we must await further materials 

 before deciding about it. It occurs at great elevations, 

 16,000 — 17,000 feet, at Changla and Pang-chong, in 

 Ladak. 



Capt. Graham Young wrote of Eogene — "I have only 

 found this insect in July and August, in the Upper 

 Chandra Valley, at 11,000 feet and upwards. It flies 

 with great rapidity, and is very difficult to capture. It 

 frequents the patches of flowers scattered amongst the 

 boulders and glaciers of that inhospitable region."

This species is found in the high mountains of 

 Kuldja, at 7000 — 12,000 ft., and, according to Alpheraky, 

 is ver}^ distinct from C. Thisoa, both in the elevation of 

 its habitat, its flight, which is very swift, like that of 

 Eogene, and other points. The only two specimens I 

 have seen of it in Mr. Godman's collection are, however, 

 not sufficient to form an opinion ; but Mr. Alpheraky 

 sends me the following points of distinction : —
