408 L. de Niceville & Dr. L. Martin — Butterflies of Sumatra. [No. 3, 
155. Neptis tiga, Moore. 
Butler. Staudinger as tiga and dorelia. I have a very long suite 
of specimens of this species, and after careful comparison have come 
to the conclusion that N. dorelia, Butler (1877), N. sattanga, Moore 
(1881), and N. kuhasa, de Niceville (1886), are all synonyms of N. tiga, 
Moore (1858). To this list will probably have to be added Rahinda 
[sic] siaka , Moore, Trans. Ent. Soc. Bond., 1881, p. 311, described 
from Sumatra, as the description agrees exactly with, some specimens 
of N. tiga I possess from Perak in the Malay Peninsula and Sumatra. 
The variation observable in N. tiga is obviously mainly due to season, 
the dry-season form being sparsely banded with black on the underside, 
the wet-season form heavily so. Of the three small yellow Nejptes , 
N. Tiordonia is the commonest, whereas N. paraka and JSf. tiga are both 
rare, especially the latter. They all occur in large and high forest, 
but are most frequently found on the boundaries of the forest, or just 
within the borders, where there is considerable sunshine. They are 
very weak-flying insects, and are easily captured when at rest with wide 
spread wings on the leaves of low bushes and on flowers. N. Tiordonia 
occurs in the plains up to Bekantschan, the other two prefer higher 
elevations, and have been caught as high as Soengei Batoe. 
156. Neptis batara, Moore. 
N. batara, Moore, Trans. Ent. Soc. Lond., 1881, p. 310. 
Moore. Snellen as miah. Originally described from Sumatra. 
N. batara has been described and figured by Distant in Bhop. Malay., 
p. 444, n. 13, pi. xli, fig. 14 (1886), as N. miah, var, from Perak. 
It is very doubtfully distinct from N. miali , Moore. Pound only on the 
higher hills at Soengei Batoe and the Central Plateau in July, but is 
very rare. 
157. Neptis sankara, Kollar. 
Excessively rare, Dr. Martin obtained a single male from the 
Battak mountains in October, 1894. It is more intensely black and 
white than typical N. sankara, but the markings are similar. The 
N. arnba and N. carticoides , both of Moore, are synonyms of this species, 
as probably also is N. amboides , Moore. 
158. Neptis thamala, Moore. 
N. thamala, Moore, Journ. Linn. Soc. Lond., Zoology, vol. xxi, p. 3d, pi. iii, 
fig. 1, female (1886). 
Originally described from Lower Burma. It is very rare in Sumatra,
