The green scales when seen through a microscope are broader than they 

 are in the Manipur Z. zoa, and consequently closed together. 



Zephykus jakamensis, n. sp. (PI. IV, Figs. 32, 33, S $ ). 



Male. Upperside : both wings bright shining green. Forewing : termen 

 broadly margined with black as in Z. biru]}a. Hindwing : costa broadly 

 brown black ; termen narrowly bordered with black and irrorated 

 with blue scales. Dorsal margin brown, greyish towards the base. 

 Underneath very similar to Z. syla but the colour greyish silvery and not 

 bluish silvery, all the markings narrower ; no sub-costal streak in interspace 

 7 ; the two submarginal spots on either side of the tails pure black with no 

 trace of any orange. Female. Ufperside : very similar to Z. syla but the 

 ground colour paler. The forewing has the terminal black border inwardly 

 produced for some distance along the dorsal margin and consequently the 

 bluish discal area is smaller ; apex of cell and outer half of interspace 

 whitish, the area beyond the end of the cell and interspaces 2 and 3 almost 

 white. Hindwing: the bluish-grey scales more conspicuous and extensive 

 almost covering the entire wing below vein 6 with the exception of a very 

 narrow terminal area ; veins brown and conspicuous. Underside similar to 

 male. 



Expanse: 6 3 1-4"— 1-63"; $$ 1-45". 



Two males were taken at Phesima in the Naga Hills at 7,000 feet in June 

 and several more males and a single female at the same place in July. 

 Three males taken on Suroifuiat about 8,000 feet in July. It can at once be 

 distinguished from its nearest allies Z. birupa, Z. syla and Z. assamica, Mihi, 

 described below, by the complete absence of any red in the vicinity of the 

 tornal black spots. 



Zephykus assamica, n. sp. 



Male. Upperside : very similar to Z. syla but pure green and never tinted 

 with bronze. Hindwing : terminal black border rather narrower and in- 

 wardly irrorated with blue scales. Underside : markings on the whole finer 

 than in Z. syla especially on the hindwing. Forewing : costal end of post- 

 discal band not conspicuously broader than the tornal end, generally 

 narrower. Hindwing : tornal black spots much smaller, the inner one often 

 obsolescent, and orange markings not nearly so conspicuous. Female. 

 Upperside : Forewing : ground colour darker, otherwise similar. Hindwing : 

 darker, of the same colour as the forewing, and much more extensive than 

 in 2 ^- syla, generally quite reaching the termen but sometimes just stop- 

 ping short of it. Underside : as in male. 



Expanse : 3 3 1-49"— 1-58" ; ? $ 1-31"— 1-63". 



A good number of males and females were taken in the Naga Hills at 

 about 7,000 feet in July and August, and a few in Manipur during the same 

 months en Kabru, 8,400 feet, and on Suroifui at about 8,000 feet. A c? 

 specimen from Sikkim has been given me by Mr. E. OUenbach. This form 

 is probably an eastern race of Z. syla. 



Zephykus kikbariensis, n. sp. (PI. IV, Figs. 36, 37, J ?). 



Male. Upperside.: very similar to the preceding form but the black border 

 on forewing is very much narrower. Hindwing : black border rather narrower 

 especially near the tornus and the blue scales more restricted, generally 

 only visible as a narrow line on either side of the tail. Underside: Fore- 

 wing : very similar. Hindwing : very similar but the discal band is very irre- 

 gular, the portion beyond the cell in interspaces 4 and 5 projecting beyond 

 the portions on either side in interspaces 3 and 6. Female. Upperside : 

 very similar to the female of the preceding form. Underside: as in male.
