118 BUTTERFLIES. 



6. Danais (Caduga) melaneus, Moore. 



Less common at low elevations only than any of the species 

 previously named except D. Umniace, Cramer. It is found in Western 

 and Central China. 



7. Danais (Caduga) tytia, Gray. 



The rarest of all the species of the genus occurring in Sikliim 

 except D. limniacc, and is found at a higher elevation than any of them, 

 flying as high as 9,000 feet above the sea in native Sikhim. 



8. EuPLCEA (Crastia) core, Cramer. 



A butterfly more of the plains than of the hills, found somewhat 

 commonly at low elevations throughout the year. Mr. Moore gives 

 Crastia vermiculata, Butler, from Sikhim instead of E. core, but Sikhim 

 examples are typical B. core; and even were they typical £. vermi- 

 culata, I am not prepared to admit that species as distinct ; at best it 

 is but a " local race," and may be only a seasonal form. Further, the 

 Tronga nicovillci described by Mr. Moore in Lep. Ind., p. 77, pi. xx, 

 figs. 1, la, male; \h, \c, female (1890), from the Sunderbuns near 

 Calcutta, is not only in my opinion of the same subgenus as E. core, 

 but is at best a local race (possibly a seasonal winter form) only of 

 that species. 



9. Euplcea (Penoa) doubledayi, Felder. 



Heer P. C. T. Snellen has recently pointed out that the Euplcea 

 alcatho'c of Godart, by which name this species is usually known, is an 

 Amboina butterfly and does not occur in India, so Felder's name must 

 be adopted for the species. It is very rare in Sikhim, though quite 

 common in Assam. In the Indian Museum, Calcutta, there is a single 

 male example obtained by Schlagintweit, and in 1889 Major C. A. R. 

 Sage obtained another specimen. These are all the examples I know 

 of from Sikhim. 



10. Euplcea (Penoa) deione, Westwood. 



Rather rare, and only occurs in the low valleys. In Baling it is 

 found more commonly. 



11. Euplcea (Trepsichrois) LINN.EI, Moore. 



This species is more generally known as E. midamus, Linnaeus. 

 It is the commonest species of the genus occurring in Sikhim, and 

 actually swarms at times in the low valleys. It is found in Western 

 and Central China. 



12. Euplcea (Danisepa) diocletianus, Fabricius. 



A somewhat rare species, occurring only at low elevations, 

 I have seen it flying once only in Sikhim. Mr. Moore in " Lepidoptera 

 Indica" has given a new name, Danisepa ramsayi, to the Nepal and 

 Sikhim form of this species, which is the whitest of all. The Assam,
