1895.] L. de Niceville & Dr. L. Martin —Butterflies of Sumatra. 409 
Dr. Martin lias obtained three or four specimens only, one of which 
from Namoe Oekor is in my collection, taken in October. 
159. Neptis yikasi, Horsfield. 
Hagen as vihasi, 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. viJcasi, Horsfield. Mr. Moore describes it as being “a much blacker 
insect both above and below ” than that species. It is unknown to us. 
161. *Heptis 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. Heptis 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 , Lepecliin, of Europe, appears to me to be distinct from the pre¬ 
sent species, as it has the white bands on the underside of both wings 
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. Loud., 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-
