BUTTERFUES. 129 



87. Melanitis bela, Moore. 



Rath&r rare in Sikhim, and occurs only at low elevations. The 

 wet-season form is M. aswa, Moore, and M. tristis, Felder ; the dry- 

 season form is true M. beta. 



88. Melanitis zitenius, Herbst. 



Commoner than M. hela, less common than M. ismene. In Sikhim 

 it is found at low elevations. It is seasonally dimorphic as usual, 

 though less markedly so than the other species in the genus ; the wet- 

 season form has not been named; the dry-season form is the true 

 3£. siienius, as is also M. dtcri/odaim, Felder. 



89. Cyllogenes suradeva, Moore. 



Very local, occurring at Singla at about 2,000 feet, from April to 

 June. I suspect it is single-brooded. 



90. Cyllogenes JANETS, de Niceville. 



A very rare species, which has hitherto only been obtained by 

 native collectors at or near Buxa in Bhutan, and by Mr. W. Doherty 

 in the Naga Hills. 



Subfamily Elymniin^. 



91. Elymnias undularis, Drury. 



Occurs in the Terai and at low elevations only in the outer 

 valleys, where it is common. 



92. Elymnias malelas, Hewitson. 



Usually known as JE. Icucocyma, Godart, described from Java, 

 but Heer P. C. T. Snellen has recently pointed out that the descrip- 

 tion of E. Icucocijma refers to a butterfly allied to, if not identical 

 with, E. undularis, Drury, and does not at all apply to the present 

 species. That being the case, the name given to it by the late 

 Mr. Hewitson is adopted. It is not a rare species in Sikhim at low 

 elevations, and is generally found where plantains are growing, on 

 which the larva feeds. 



93. Elymnias timandra, Wallace. 



It is more than probable that the name given to this butterfly by 

 Mr. A. R. Wallace should fall before E. lais, Cramer, the two species 

 hardly at all differing, and Cramer's name being the older. It is 

 excessively rare in Sikhim. I have seen only two specimens from 

 thence, both females, which were taken in the low hot valleys. Mr. 

 Dudgeon's collection also contains three females, one from the Tista 

 valley, and two from the Geet valley (2,000 feet). 



94. Elymnias (Dyctis) patna, Westwood. 



Not very common in the low valleys up to 3,000 feet from April to 

 October; in the latter month I have captured it in the Ruajit valley.
