NOTES ON BUTTERFLim FROM THE NAG A HILLS. 515 



A third form from the Western Himalayas was taken by myself at 

 Loharjang in Western Garhwal, at 6,600' in May, which does not agree with 

 either typical P. janaka, P. bootes, or with P. mixta, Mihi, and which I 

 propose naming P. kala. 



P. KALA, n. sp, 



Male. Upperside : on the hindwing there are three white discal spots in 

 interspaces 2, 3 and 4, both above and below, and there is a subterminal 

 series of red lunules in interspaces 1 — 4 as in P. janaha but smaller ; the 

 tornal one does not coalesce with the admarginal one as it sometimes does in 

 that species. Underside : the hindwing agrees with P. bootes in having the 

 red basal area confined to the base and not produced along the dorsum as 

 in P. Janaka. It differs from both P. janaka and P. bootes in having the tail 

 completely black and not spotted with pinkish white as in those two species 

 resembling in this respect P. bootes nigricans, Rothsch. 



P. janaka, P. mixta, mihi, and P. kala, mihi, will probably prove to be 

 conspecific with P. bootes, which in the Eastern Himalayas, in the Khasia 

 Hills, and in Manipur and the Naga Hills has developed into well marked 

 and constant forms whilst in the Western Himalayas it is still inconstant 

 and is represented by three distinct forms, viz., typical janaka, bootes and 

 kala, mihi. 



Papilio KRISHNA, Moorc. 



A single male taken above Yakama, Naga Hills, in May. It is much rarer 

 in these Hills than it is in Manipur. It appears to be single brooded. 



Papilio aristeus anticrates, Doubl. 



Several males of this form were taken in March at Sebong in the Eastern 

 Manipur Hills and in the Kabor Valley, Burma, about fifteen miles from 

 Sebong, flying with P. aristeus hermocrates, which was the prevailing form 

 occurring somewhat commonly. 



P. ARISTEUS HERMOCRATES, Felder. 



A single male was taken at Nichuguard in the Naga Hills, in May, where 

 the prevailing form P. aristeus anticrates occurs commonly in March and 

 April. 



Leptocircus meges istdistincta, Tytler. 



Occurs rather rarely in the Manipur Hills. Several females which difl'er 

 in no way from the males were obtained in the Naga Hills. This sex appears 

 to be exceedingly rare. 



Teinopalpas imperialis, Hope. 



Occurs very commonly in the Manipur Hills at high elevations. A few 

 females were taken on Kabru Peak from May to July. The spring females 

 are somewhat smaller than those taken in the rains. 



Family— PIERID^. 



PlERIS BRASSIC^, L. 



During the years 19II and 1912 1 only obtained a single male in Manipur ; 

 but during the present year 1913 this butterfly simply swarmed in my 

 garden from March to May ; the caterpillars doing great damage in the 

 kitchen garden. The walls of my bungalow were favourite places for the 

 caterpillars to pupate on and htradreds of pupse could be seen hanging from 

 them in sheltered spots.
