NAG A HILLS BUTTERFLIES. 131 



Expanse: 6 6 1-45"— 1- 58" ; $ 5 1'5"— 1-59." 



A few males and females taken on Kabru, Manipur, 8,400 feet, in July and 

 August, and several males and females in the Naga Hills at Kohima, Phe- 

 sima and Kirbari at about 7,000 feet from July to September, a single female 

 at Jakama in October and a single male at Kohima in November. A 5 of 

 this species was originally taken at Kirbari in the Naga Hills and recorded 

 in the J. B. N. H. Soc, Vol. XXI, p. 598, as being very near to Z. si/la. 

 I did not like to separate it on a single specimen ; it is however a perfectly 

 good species. The shape of the discal band on the underside is very 

 characteristic and at once distinguishes it from its nearest ally Z. assamica, 

 Mihi, which has the discal band generally straight and if not straight 

 the portions beyond the cell in interspaces 4 and 5 are somewhat more 

 inwardly placed than portions in 3 and 6 and not outwardly as in the present 

 form. The 12 S 6 and 8 $ $ now before nie show no variation in the 

 shape of this baud. 



Zephyktjs paona, n. sp. (PI. IV, Fig. 34, 35, c? $). 



Male. Upper side : both wings very similar to Z. kirbariensis. Hindwing 

 with a blue terminal line on either side of the tail. Underside : bluish 

 silvery white. Forewing : a brown streak closing the cell ; a postdiscal 

 narrow brown band consisting of semi-detached streaks ; a very indistinct 

 subterminal band darker than the ground colour ending in distinct black 

 spots near the tornus, a very indistinct terminal line slightly darker than 

 the ground colour and lastly an anteciliary dark narrow line. Hindwing : a 

 narrow sub-basal brown streak in interspace 7 not quite reaching its lower 

 edge ; another similar streak closing the cell, a very sinuous irregular discal 

 band, deeply excavated in interspace 1 and then sharply recurved to the mid- 

 dle of the dorsum ; a subterminal band of indistinct dark lunular spots, rather 

 more conspicuous in interspace 1 and 2 where they are inconspicuously bor- 

 dered posteriorly with orange ; a terminal row of very inconspicuous spots 

 slightly darker than the ground colour and lastly an anteciliary narrow dark 

 line. Cilia white. Female. Ujjjjerside: very shwilav to the 5 of Z. kirba- 

 riensis, Mihi, but the discal white spots are much more conspicuous ; inter- 

 spaces 2 and 3 being completely white from the base to the terminal black 

 border. Hindwing : also very similar but interspaces 4, 5 and 6 are whitish 

 towards the termen ; a distinct brown terminal border ; an anteciliary dark 

 line inwardly bordered with blue on either side of the tail. Underside 

 similar to male but the discal bands on both wings rather more heavily 

 marked and more distinct. 



Expanse: J 1-71"; $ 1'67". 



A single male was taken on Kabru Mountain, Manipur, 8,400 feet, in June, 

 and a female during the same month on Paona Peak at about 8,000 feet. 

 This beautiful species can at once be distinguished from its nearest ally 

 Z. kirbariensis, Mihi, by the form of the discal band on the underside of the 

 hindwing which at its anterior end consists of semi-detached lunular 

 streaks, the streak in interspace 6 projecting beyond those in interspaces 

 4, 5 and 7; in Z. kirbariensis, the discal band is continuous at its anterior end 

 and the portions between the veins are straight, the portion in interspace () 

 does not project outwardly but is more inwardly placed than portions in 4 

 and 5. 



Zbphyrus khasia, de N. (PI. IV., Fig. 44, $ ). 



Female. Very similar to Z. kirbariensis $ on the upperside and cannot be 

 distinguished from it except by the absence of the tail on the hindwing. 

 Underside : exactly as in the male. This species has hitherto been only 

 known by a single male taken in the Khasia Hills a long time ago. Its
