BUTTERFLIES CAUGHT IN S. E. TIBET. ' 637 



18. Zipcetis scylax, Hewit. Two males on the Lower Tsang Po, at 3,000 

 feet early in June. 



19. Ypthima neioara, M. 42 specimens on the Lower Tsang Po and in 

 the Po Chu Valley, also one at Pemako Chung, at 3,000 to 9,000 feet in 

 June and July ; a single specimen at Dhirang, 5,000 feet in October. 



They agree best with the eastern race sarcaposa, Fruh, of which I have 

 specimens from Manipur. They may, however, be referable to chinensis, 

 Leech, which does not seem to be specifically distinct from neioara. 



20. Ypthima baldus, Fabr. 1 S , Dewangiri, 1,000 feet, November. 



21. Ypthima affectata, Elwes and Edw. 2 5 , Lower Tsang Po, 3,000 feet, 

 June. 



22. Ypthima methorina medusa, Leech. 4 specimens on the Lower 

 Tsang Po, 3,000 to 8,000 feet in early June. Agrees as to races with the 

 Indian persimilis, El and Ed, but is smaller and with the wings rounded. 



23. Ypthima sahra, M. 69 specimens, 4,500 to 9,000 feet, mostly on the 

 Lower Tsang Po, the Po Chu Valley and one at Pemako Chung, May to July, 

 a few at Dhirang in October. They agree best on the whole with the Sik- 

 kim form, true sakra, but many are inseparable from the eastern race 

 austeni, M. In most of the specimens the subterminal dark areas on the 

 underside are obsolete.
