NAG A RILLS BUTTERFLIES. 135 



Arhopala araxa, n. sp. 



A male of a form which appears to be new was obtained on the Lengba 

 River, Western Manipur HiUs, and two more at Sebong, Eastern Manipur 

 Hills, in March and April. It agrees with nothing in the De Niceville 

 collection. 



The upperside is similar to specimens of A. arao, Hewitson, and the under- 

 side to A. agrata, De N., in the De Niceville collection. 



Arhopala khamti, Doherty. 



A single male taken at Sebong in May agrees with specimens in the De 

 Niceville collection. 



Arhopala rama, Koli. 



Common at low elevations in Manipur. The breadth of the black terminal 

 border of the forewing is variable. 



Arhopala, sp. ? 



Three males and two females of a form intermediate between A. rama 

 and A. hewitsoni taken in Manipur and the Naga Hills from March to July. 



Arhopala hewitsoni, Bethune-Baker. 

 A pair taken at Sebong in June. 



Arhopala albmon, De N. 



Numerous males of the dry-season-focm taken at Sebong, Manipur, in 

 January and February and a few at Imphal in May ; and numerous wet- 

 season-forms at Sebong from June to January. The sexes hardly differ ; 

 the female has the terminal black border on forewing very slightly broader 

 and the black tooth at the end of the cell more pronounced. This tooth is 

 nearly always to be seen in the male but is glossed over with purple. In 

 two dry-season males the purple gloss has entirely obliterated the black 

 tooth. 



From the dates of capture it will be seen that typical wet-season-forms 

 fly on well into the cold weather. The black border on the forewing is 

 broader in the wet-season-form than in the dry-season-form. 



Arhopala comica, De N. 



Two females of this curiously marked species were obtained at Sebong, 

 Manipur, in March and agree exactly with De Niceville's type. Mr. Bethune- 

 Baker believed this to be a sport of A, dodonea (T.Z.S., 1903, p. 134). The 

 type I believe was then unique. The tail is much longer than it is in dodonea 

 and of a dift'erent shape. I believe it to be a good species. 



Arhopala tounguva, G. S. 



A large series of males and females obtained at Sebong, Manipur, in June 

 which agree with specimens taken by Mr. EUis at Kankerait, Shan States, in 

 May and at Tangbingon, Upper Burma, in December. The males differ 

 considerably from eight males I have from Rangoon, Lower Burma, taken in 

 April, in having on the uppevside the blue much duUer and the black border 

 slightly broader ; and on the underside in being paler and not so suffused 

 with pink.
