THE BUTTERFLIES OF KUMAUN. 367 



the preceding. Whether these two latter forms are entitled to specific 

 rank is very doubtful. 



Sub-Family — Theclinte. 



269. Zephyrus ataxus, Hewitson. — Rare at Naini Tal and Binsar, .July 

 to September, at 6-8,000 ft. 



270. Zephyrus syla, Kollar. — Common at Naini Tal, Muktesar, Binsar, 

 Dhakuri, in April, September and October, at 6-9,000 ft. 



271. Zephyrus birupa, Moore.— Not common. May, June and October. 

 Nalena, Ramgarh, Binsar and Naini Tal, 4,500-8,000 ft. 



272. *Zephyrus icana, Moore.— -"Rare at Dhakuri, 9,000 ft., Chaudans. 

 N. E. Kumaun" (Doherty). 



273. Zephyrus triloka, sp. n. 



Female. — Upperside : ground-colour grey-blue of a duller shade than that 

 of L. liba, Hewitson. Forewiny, apex and outer margin fuscous brown, an 

 irregular white patch at apex of cell more restricted in area than the 

 similar patch in L. syla $ ; Hindwing dull brown with grey-blue irrorations 

 in the interspaces. 



Underside: — Silvery-greenish-white with discal and sub-marginal streaks 

 arranged as in L. syla but of a much paler shade of brown, the two black 

 anal and sub-anal spots reduced to mere dots and without any trace of 

 orange margins. 



Male — Unknown . 



The three specimens before me were all brought in from the Pindari 

 Valley in August by a native collector. I have named the form as above 

 with some reluctance, remembering the case of L. katura. It is, however, 

 abundantly distinct from the § of either L. syla or L. birupa, its nearest 

 allies, especially on the underside, nor is it very near L. mandara, Doherty, 

 of which the $ has yet to be discovered. 



The underside is also quite unlike that of the specimens of L. liba in the 

 British Museum. 



274. Zephyrus dohertyi, de Niceville. — "N. "W. Kumaun," (Doherty). He 

 does not specify the exact locality. I have received a single male from 

 the Pindari Valley in August. 



275. Zephyrus mandara, Doherty.— "N. W. Kumaun," (Doherty). 



These last four species are apparently confined to the inner ranees 

 bordering on Tehri Garhwal and the snow-line. 



276. Euaspa milionia, Hewitson. — Occurs sparingly at Binsar, 8,000 ft. in 

 June. This is its first recorded locality in Kumaun, though it is apparently 

 common in Mussoorie and Kulu. 



277. Chsetoprocta odata, Hewitson. — Fairly common in April and May 

 and from July to October at 8-10,000 ft. in the neighbourhood of walnut 

 trees on which its larva feeds. 



278. Chrysophanus phlseas, Linn. — Common in the rains at 5-9,000 ft.
