BUTTEEFLIES. 137 



145. Neptis nana, de Niceville. 



Occurs at Tonglo and in Bhutan in April and June, but is a very 

 rare species. It is near to, but quite distinct from, iV. saida. 



146. Neptis nycteus, de Niceville. 



This is No. 131, Neptis mcmasa, Moore, of Mr. Elwes' list. He 

 took a single male in the forest near the Rangbi jhora, on the road 

 to Serail, at 6,000 feet, in June. The type specimens were obtained 

 in June and July at Tonglo on the Singalela range at about 

 12,000 feet. Found by Mr. Dudgeon at 7,000 feet in Baling. 



147. Neptis sankara, Kollar. 



I have examined the type specimen of this species, which is a 

 female, in the collection of the natural history museum at Vienna, 

 Before it must fall iV. amha, Moore, N. cartico'idcs, Moore, and 

 probably N. amhoidcs, Moore, It is a rare species in Sikhim at 

 3,000 feet, but is far commoner in the Western Himalayas. Mr. Leech 

 records it from Western and Central China as N. amha, but the Chinese 

 form diflFers greatly from the Indian one in having all the bands and 

 spots of the upperside yellow instead of white. 



148. Neptis caetica, Moore. 



Certainly not a common species in Sikhim, though it is more 

 often met with tlian N. sanJcara, Kollar. It is found in the lower 

 valleys throughout the warm weather. 



149. Neptis vikasi, Horsfield. 



The commonest species of this group in Sikhim, and occurs at 

 low elevations almost throughout the year. 



150. Neptis leucothoe, Cramer. 



Cramer figures this species well in his Pap, Ex., vol, iv, page 15, 

 pi. ccxcvi, figs. E, F (1780), and records it from Java, China, and 

 the Coromandel Coast of South India. It has received many names, 

 N, euryiiome, Westwood; N. varmona, Moore; N. disnipta, Moore 

 (a "sport" or aberration); N. adara^ Moore; N. mcetana, Moore; N. 

 swinhoei^ Butler ; N. Jcamarupa, Moore ; N. ciirymenc, Butler ; N. andaniana, 

 Moore ; N. nicobarka, Moore ; N. mamaja, Butler ; iV, sanf/aica, Moore, 

 &c. My impression is that none of these will stand. If the Eui-opean 

 iV. aceris, Lepechin, is admitted by the best entomologists to extend 

 from Europe through Northern Asia to Corea and Japan, there can. 

 I think, be little doubt that iV. leucothoe, Cramer, has a similar ex- 

 tended range, being found throughout India (except in the desert 

 tracts) from Bombay on the west, Ceylon on the south, through 

 Burma, the Malay Peninsula, Siam, Cochin China, &c.. South, 

 Central, and Eastern China, and all the Malay Islands to the west of 

 AVallace's line, and in Formosa and Hainan. In those portions of
