506 h. de Niceville & Dr. L. Martin-* Butterflies of Sumatra. [No. 3, 



is not very rare at Selesseh and in the outer hills as far as Bekantschan, 

 and is found from March to September, hut not in any other month. 

 The female is decidedly rare, and always has the basal markings on the 

 upperside of both wings gamboge-yellow. It is a beautiful mimic of 

 Danais aspasia, Fabricius. 



563. Huphina nadina, Lucas. 



Snellen. Hagen as remba. The Huphina remba of Moore is a quite 

 distinct species, and is confined to South India and Ceylon. H. nadina 

 is very common at high elevations, at Soengei Batoe and on the Central 

 Plateau, on the sandy banks of hill streams throughout the year. The 

 female is very rare, and Dr. Martin has only obtained two specimens in 

 thirteen years. 



564. Huphina nerissa, Fabricius. 



Hagen as Pieris nerissa, Fabricius, var. sumatrana, Hagen. H. ne- 

 rissa appears to be the oldest name for the species of this group, and 

 was originally described from China, Butler records it from Hong-Kong, 

 the Indian forms of which, generally known as H. phryne, Fabricius, 

 appear to be highly variable and subject to seasonal dimorphism in all 

 localities where the climate exhibits two well-marked seasons, a wet and 

 a dry. Even specimens from a limited area and an equable climate like 

 the Battak mountains in Sumatra shew considerable variation in the 

 coloration of the underside of both wings, some examples being much 

 richer yellow than others, and the black lining to all the veins greatly 

 differing in width. It is much rarer than the foregoing species, but is 

 found in the same localities from April to September, most numerous in 

 May and July. Dr. Martin possesses no female. 



565. Huphina lea, Doubleday. 



Grose Smith as var. naomi. Snellen. Hagen as lea and amalia. 

 Wallace as amalia. Kirby as amalia. Distant as amalia. The 

 "Pieris" naom&i Wallace, was described from Lombock and Flores, and 

 is not at all likely to occur in Sumatra. " Pieris " amalia, Vollenhoven, 

 was originally described from Sumatra and Banca, a female from the 

 latter island being figured. Vollenhoven gives for " Pieris " lea the 

 islands of Borneo and Banca, so that both species according to him 

 occur in the latter island. Wallace keeps the two species distinct, and 

 gives Borneo and Banca for H. lea, Singapore and Sumatra for 

 H. amalia. I have a large suite of specimens of H. lea from Burma, 

 the Malay Peninsula, Sumatra and Borneo, and am unable to find any 

 constant character by which H. amalia can be distinguished from it.
