*111. IxiAS, sp. 



Ixias pallida, Moore, Proc. Zool. Soc. Lond., 1878, p. 837. 



Ixias citrina, Moore, 1. c. 



Ixias moulmeinensis, Moore, 1. c. 



We do not know to which, if any, of these species the numerous 

 male specimens of Ixias in this collection should be referred. Though 

 they are smaller, they seem to come nearest to J. andamana, Moore, 

 to which Mr. Moore says his I pallida is nearest, but we cannot believe 

 that in this very variable genus anything like the number of described 

 species really exists. Some of the Tenasserim specimens might be also 

 called I. hirdi, Distant (from the Malay Peninsula), or /. verna, Druce 

 (from Siam), but on the whole we prefer to leave the matter undeter- 

 mined until the whole genus can be examined critically. 



112. NePHERONIA GMk. 



Eronia goea, Felder, Reise Novara, Lep., vol. ii, p. 190, n. 188 (1865). 

 A male, and a female with yellow at the base of the hind wing, from 

 Tavoy. 



Nepheronia lutescens, Butler. 

 Eronia lutescens, Moore, Proc. Zool. Soc. Lond., 1878, p. 838. 



Has this species ever been described ? Mr. Moore gives no refer- 

 ence to it. He records it from Sumatra, as well as from Moulmein to 

 Meetan.
