BUTTERFLIES CAUGHT IN S. E. TIBET. 543 



from. Seitz"s figures and very brief description ; they do not, however, differ 

 from the specimens caught by Capt. Bailey in 1911 and identified by Mr. 

 South as axpasia. Men. ( J. B. N. H. S. xxii. 603). Alvinda appears to differ 

 from the Indian zaueha, M. in that the outer margin of the hindwing is not 

 crenulate between the tail at the end of vein 3 and the anal angle. 



143. Colias herylla, Fawe. 10 specimens in the high country south of 

 the Tsang Po at 14-16,000 feet, in September. All the specimens very 

 worn. Berrylla seems to connect motium, Ober. with ladakensis, Fd. The 

 females obtained were pale yellow like the males. 



144. CoLias cocandicaj^T&ch.. (see plate). 7 specimens caught with berrylla 

 and a few at Lu on the Tsang Po, 14,000 feet, August. I leave the correct 

 name to a Colias expert. 



145. Bercas lycorias, Doubl. 8 specimens. Lower Tsang Po, 5,000 feet, 

 May and near Dhirang, 7,000 feet, October. 



146. Tenas laeta, Bdl. 2 S , Nyamjang Valley, 6,000 feet, October. 



147. 2e?7as sz'ZAetewa, Wallace. 1 S , Dewangiri, 1,500 feet, November. 



148. Terias Jiecabe, L. 7 specimens, Dhirang and Nyamjang Valley, 

 6-7,000 feet, October. 



149. Cyaniris marginata, de N. Id, Lower Tsang Po, 4,000 feet, June. 



150. Cyaniris alboc<srulea, M. 2 J , Lower Tsang Po, 4-7,000 feet, June. 



151. Cyaniris dilecta, M. 1 c?, Dhirang, 6,000 feet, October. 



152. Cyaniris argiolus jynteana, de N. 15 specimens. Lower Tsang Po 

 and Po Chu Valley, 4-8,000 feet, May and June ; also near Dhirang and the 

 Nyanjang VaUey, 6,000 feet, October. One of the specimens obtained in 

 the first-named locality is quite different to the remainder, it resembles 

 coelestina, KoU, in having the black border on the forewing above narrow, 

 but widening at the apex, but the cilia are prominently chequered with 

 black at the ends of the veins and there is an indistinct pale discal patch ; 

 below the spots are arranged as in the argiolus group, the spots on the fore- 

 wing are, however, linear, that in space 3 being oblique, while the spots on 

 the hindwing are large, prominent and rounded, 5 that in space 3 being pro- 

 duced outwardly. 



153. Cyaniris areas, Leech. 80 specimens mostly in the Po Chu Valley, 

 7-8,000 feet, June and July ; a few at Migyitun, 10,000 feet, September 

 and at Tawang, 8,000 feet, October. The Migyitun specimens averaged a 

 good deal smaller. 



154. Cyaniris morsheadi, n. sp. ( see plate ). 64 specimens on the Tsang 

 Po between Gyala and Lapso, 9-14,000 feet, July and August ; also a few 

 between the Khamba La and the Kongma La, south of the river, 12,500 

 feet, September. 



Male dark-blue above, a good deal darker than is usual in this genus; the 

 black border very broad, rather broader than in transpecta, M., of uniform 

 width, curved round somewhat at the apex of the forewing : costa of the 

 forewing very narrowly black, the costa and inner margin of the hindwing 

 dusky. Below the pattern is exactly similar to that in the argiolus-oreas 

 group ; all the spots are small and rounded, everywhere complete : on the 

 hind wing there is a greenish tinge increasing in intensity towards the base. la 

 the female the blue colouration is very dark and restricted to a large patch 

 in the middle, the rest of the forewing being black ; there is black spot at 

 the end of the cell ; the hindwing is uniform black with an obscure deep- 

 blue sheen towards the base. Size intermediate between coelestina and
