the Pierine Genus Huphina. 213 



The following subgroup contains species in which the 

 sexes differ somewhat in the manner of Phrissura cegis in 

 their upper-surface pattern, but on the under surface they 

 show a good deal of olive-green colouring in their wet and 

 intermediate phases. I know of no other Pierinse which at 

 all closely resemble them.

H. nadina was described from a male of the wet phase and 

 a female of Appias zehnira, H. nama from a male of the 

 intermediate and a female of the wet phase, H. amba and 

 amboides from males of the dry phase. H. amboides differs 

 from H. amba in the absence of the sandy-brown discal band 

 on the under surface of the secondaries ; as it occurs in the 

 same localities as the typical phases of the species, it i3 not 

 likely to be more than an extreme development of the dry 

 form. 



55. Huphina Andersoni.

Allied to the preceding species, but the apex of the 

 primaries and the secondaries below rich golden yellowish. 



56. Huphina andamana. 



Huphina nama, var. andamana, Swinhoe, P. Z. S. 1889, p. 398. 



Andamans. Twelve examples, B. M. 



The intermediate phase differs from the wet in the much 

 browner coloration of the apex of the primaries and the 

 secondaries below, the spot in the centre of the latter wings 

 white instead of canary-yellow: in the dry phase there is 

 scarcely any yellow left upon the under surface and the apex 

 of primaries and secondaries are paler and greyer ; the outer 

 border of the primaries above is also slightly narrower.
