138 BUTTERFLIES. 



India whicli have a well-marked dry- and wet-season, seasonal forms 

 occui', the wet-season form being true N. lemothoe, and the dry- 

 season N. Icamarupa ; the other names can be fairly evenly divided 

 between these two forms. In Sikhim, as elsewhere, it is a very com- 

 mon species, and occurs everywhere at from 7,000 feet to the level 

 of the plains throughout the warm months. 



151. Neptis astola, Moore. 



N. emodes, Moore, cannot I think be maintained as a species distinct 

 from iV. astola. It is perhaps hardly a less commoa species in Sikhim 

 than N. kucothoc, Cramer, and occurs at the same time and in the 

 same places. 



152. Neptis nandina, Moore. 



It has recently been discovered that the type specimens of 

 iV. nandina and N. soma, both described by Mr. Moore, represent one 

 and the same species, the name iV. sojna, by which the species is 

 generally known, having to fall before the older name, JV. nandina. 

 What has hitherto ia India passed as iV. nandina, has been named 

 JSf. yerburii, by Butler. In Sikhim N. nandina occurs at low and 

 medium elevations throughout the summer months. It is found also in 

 Western China. 



153. Neptis yerbueii, Butler. 



Generally known in India as N. nandina, Moore. Not uncommon 

 in Sikhim up to -4,000 feet from April to December. In Mussoorie the 

 larva feeds on Celtis atistralis, Linn. 



154. Neptis adipala, Moore. 



A somewhat rare species in Sikhim. Occurs in Western China 

 also. 



155. Neptis susruta, Moore. 



A common species, occurring throughout the warm months up to 

 5,000 feet elevation. Found also in Western China. 



15(j. Neptis ophiana, Moore. 



Common at low elevations from March to December. 



157. CiRRHOCHEOA AORis, Doubleday and Hewitson. 



Common up to about 6,000 feet from April to December. 

 C ahnormis, Moore, and C. jiraria, Swiuhoe, are both probably synonyms 

 of C. aoris, though till these two species are figured it is impossible to 

 say this with certainty. 



158. CiRRiiocnROA MiTHiLA, Moore. 



Much rarer than C. aoris; occurs in the same regions and in the 

 same months as that sjDecies. It is not uncommon at Sivoke and east 

 of the Tista river at low elevations. It has a very wide range, and
