NAG A HILLS BUTTERFLIES. 145 



Oel^enorrhinus, sp. ? 



A single male taken at Saitn, Manipur, 4,000 feet, in September differs 

 from its nearest ally C. patula as follows : — 



Antennae : inner face of club white, outer face of club black except 

 at the base where it is white ; shaft speckled with black and white. 

 Upperside : Forewing : discal band consisting of only three spots, 

 much narrower than in C. patula. Hindwing : no spots on disc, only a 

 submarginal row, paler than in C. patula. 



Underside : Hindwing : spots paler and indistinct on disc. Cilia paler 



yellow, broadly chequered with black. 



This may possibly be C. sumitra, Moore, about which there appears to be 



some doubt. Major W. H. Evans who examined Moore's types informed 



me that it had no discal orange spots on upper hindwing but only a row of 



large marginal spots, agreeing with my specimen in this respect. 



Cel^nobt^hinus patula, De N. 



Numerous males and five females were taken at Kirbari and at Takabama, 

 Naga Hills, at 6,000-7,000 feet from July to September. It can be at once 

 distinguished from all other closely allied forms except C. ijero by having 

 the shaft of the antennse in both sexes anteriorly white. 



Cel^nokrhinus pero, De N. 



Apparently very rare. A single female only was obtained at Jakama, 

 Naga Hills, 6,000 ft. in September. 



Cel^enorrhinus leucocera, KoU. 



A few specimens of both sexes taken at low elevations in Manipur in 

 March, April, May and November. 



Cel^enorrhinus maculicornis, El. and Ed. 



Three males taken at Sebong, Manipur; in October and a female at Saitu 

 in May. Seven males and a female taken at Phesima, Jakama and Kirbari 

 in the Naga Hills at 6,000 feet from July to October. This form is very 

 closely allied to C. viunda. 



Cel^norrhinus chamunda, Moore. 



Very common at Sebong, Manipur, where numerous specimens of both 

 sexes were taken in March, April and June. 



CelyENOrrhinus nigricans, De N. 



A male taken on the Barak River, Western Manipur Hills, in March and 

 a female at Saitu in September. 



Cel^norrhintjs aurivittata, Moore. 



Taken very commonly at low elevations in Manipur, not so common in 

 Naga Hills where one specimen was taken as high as 6,000 ft. 



Cel^norrhinus affinis, El. and Ed. 



Two yiairs taken in Manipur at low elevations in April, May and Novem- 

 ber, and a male at Kirbari, Naga Hills, 6,000 feet in November.
