370 L. de Niceville & Dr. L. Martin — Butterflies of Sumatra. [No. 3, 



not below 3,000 feet elevation, not even being found at Bekantschan. 

 As Dr. Hagen wrongly diagnosed this species by making it a " variety " 

 of B. melaneus, Cramer, which it certainly is _not, seeing that it 

 is a local race of B. tytia, Gray ; as moreover, lie spelt the name 

 incorrectly, I refuse to accept his name for the species, though 

 it is prior to mine. In all cases where a species has been first described 

 incorrectly as a "variety" of another species, and is subsequently 

 proved to be a distinct species, it is optional for the author who so 

 proves it to be distinct to use the varietal name so given to it in a full 

 specific sense, or to rename it altogether.

Caduga banksii, Moore, Proc. Zool. Soc. Loud , 18S3, p. 251, n. 8. 

 Moore. Grose Smith as melaneus, Cramer. Semper as aglea, 

 Cramer. Hagen as aglea and melaneus. It is a good local race of 

 B. melaneus, Cramer, from the eastern Himalayas, Assam, Burma, 

 and the Malay Peninsula. Occurs on the Central Plateau and higher 

 hills as also in the plains, the specimens from the highest points being 

 richer and darker in colour than those from a lower elevation. 



17. * Euplcea (Menama) BUXTONI, Moore. 



Menama buztoni, Moore, Proc. Zool. Soc. Loncl., 18S3, p. 265, n. 5. 

 Moore. Originally described from Sumatra. Dr. Martin has hot 

 met with any species of this distinct subgenus in Sumatra. 



18. * EUPLCEA (Menama) modesta, Butler. 



Grose Smith. Originally described from Siam. It is more than 

 doubtful if two species of the subgenus Menama occur in Sumatra. Dr. 

 Hagen records quite funnily " Menama species near loeza." He does not 

 appear to know that Menama is a genus of Mr. Moore's, he treats the 

 name as specific. The species " loeza " is probably intended to mean 

 Menama lorzie, Moore, Proc. Zool. Soc. Lond., 1883, p. 265, n. 6, pi. 

 xxxi, fig. 5, male, from Sandakan, North Borneo. 



19. Euplcea (Tronga) bremeki, Felder. 



Hagen. Butler. A common species in the plains and occurs also in 

 the lower ranges of the mountains up to 1,500 feet elevation. In 

 December, 1894, and January, 1895, Dr. Martin obtained hundreds of 

 specimens from Kepras, a village on the boundary between Langkat 

 and the independent Battak country. The female is alwa3 T s somewhat 

 scarce. It may be of interest to note that out of large numbers of but- 

 tertlies of this species there are always to be found a few males which
