THE BUTTERFLIES OF MUSSOORIE. 219 



37. Ypthima sakra, Moore. 

 Very common at Mussoorie in ravines in June and July only. 

 Mr. Moore keeps Y. nikcea, Moore, from the Western Himalayas, 

 distinct from Y. sakra from the Eastern Himalayas, but we agree 

 with Messrs. Elwes and Edwards in uniting them under the older 

 name. 



38. Ypthima avanta, Moore. 



The dry-season form, true Y. avanta, is found in Mussoorie in April ; 

 the wet-season form, Y. ordinata, Butler, flies in the rains. It is not 

 common, and is not found in Dehra Dun. 



39. Ypthima huebneri, Kirby. 



Mr. Moore has described an Y, apicalis from a single male from 

 tl Deyra Dhoon." We have specimens taken in the Dun in March 

 which agree with the description and figure of that species, but they 

 certainly represent the dry-season form only of Y. huebneri, which has 

 been named Y. hoiora by Moore. The wet-season form, true Y, huebneri, 

 occurs in the Dun in the rains. It is not found in Mussoorie at all. 



40. Ypthima naeed^ Kollar. 



Common in Mussoorie only, where it flies from April to October. 

 It has no dry-season non-ocellated form. 



41. Ypthima asterope, Klug. 



Mr. Moore in Lep. Ind., vol. ii, p. 91, says that Y. mahratta, Moore, 

 " Is allied to the North-East African (Aden) species, P. asterope of 

 Klug." My Lahej (Aden) specimens of Y. asterope agree exactly 

 with the supposed distinct Y. mahtaiia, so I have no hesitation in 

 uniting them. It is common in the Dun in March and August, 

 and has both an ocellated and a non-ocellated form, the former being 

 true Y. asterope= Y. mahratta, and the latter Y. alemola, Swinhoe. 

 It does not appear to occur in Mussoorie itself, but native collectors 

 have brought it into the station from the neighbouring low valleys. 



42. Ypthima inica, Hewitson. 



We have only obtained the dry-season form of this species, the true 

 Y. inka, in the Dun in March, but the wet-season form, Y. ariaspa, 

 Moore, will certainly be found on the same ground during the rain3. 

 43. Dallacha hyagriva, Moore. 



Very common in Mussoorie only in August and September on 

 grassy hill sides.
