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 Bahinda 

 [sic] siaka, Moore, Trans. Ent. Soc. Lond., 1881, p. 311, described 

 from Sumatra, as the description agrees exactly with some specimens 

 of N. tiga I possess from Pei'ak 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 Neptes, 

 N. hordonia is the commonest, whereas N. paraka and N. 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. hordonia 

 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. hatara has been described and figured by Distant in Rhop. Malay., 

 p. 444, n. 13, pi. xli, fig. 14 (1886), as N. miah, var., from Perak. 

 It is very doubtfully distinct from N. miah, Moore. Found 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. amba 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. 30, pi. iii, 

 fig. 1, female (1886). 



Originally described from Lower Burma. It is very rare in Sumatra,
