1895.] L. de Niceville & Dr. L. Martin — Butterflies of Sumatra. 409 



Dr. Martin has obtained three or four specimens only, one of which 

 from Namoe Oekor is in my collectiun, taken in October. 



159. Neptis vikasi, Horsfield. 



Hagen as vikasi, Moore [sic]. Butler. Staudinger. A common 

 species in the plains, bat restricted to forest. 



160. *Neptis omeroda, Moore. 



N. omeroda, Moore, Proc. Zool. Soc. Loncl., 1874, p. 571. 



Grose Smith as ormeroda [sic]. Originally described from Penang 

 in the Malay Peninsula. Mr. Distant considers it to be a synonym of 

 N. vikasi, Horsfield. Mr. Moore describes it as being " a much blacker 

 insect both above and below " than that species. It is unknown to us. 



161. *Neptis harita, Moore. 



Staudinger. It is quite probable that this species does occur in 

 Sumatra, though Dr. Martin has never obtained it. Though quite dis? 

 tinct it may easily be overlooked, as it is very similar to N. vikasi, 

 Horsfield. 



162. Neptis anjana, Moore. 



Is by far the most beautiful Neptis of our area, especially the 

 underside of both wings, which exhibit very splendid colours. Is 

 found only in the hills as high or even higher than the Central Plateau, 

 3,000 feet. Dr. Martin possesses three specimens only, the first ob- 

 tained in 1894, after twelve years' collecting. 



163. Neptis leucothoe, Cramer. 



Snellen as aceris. Hagen as aceris. Certainly the commonest species 

 of the genus in Sumatra, and found almost everywhere all the year round. 

 N. aceris, Lepechin, of Europe, appears to me to be distinct from the pre- 

 sent species, as it has the white bands on the underside of both w r ings 

 not outwardly defined with black as they invariably are in both the wet- 

 and dry-season forms of N. leucothoe — the latter form not found in 

 Sumatra. 



164. *Neptis papaja, Moore. 



N. papaja, Moore, Proc. Zool. Soc. Lond., 1874, p. 570. 



Moore. Kirby. The description of this species agrees with speci- 

 mens I have identified as N. leucothoe, Cramer, the ground-colour of 

 the underside being " ferruginous-yellow ; markings prominent, black-
