BUTTERFLIES. 185 



605. NOTOCRYPTA FEISTHAMELir, Boisduval. 



Better known as Plesioncura alysos, ]\[oore. Lieutenant Watson 

 keeps the N. curvifascia of Folder, described from China, as a distinct 

 species. I have seen the type specimen at Vienni, which is a female. 

 As the white band on the underside of the forewing does not nearly 

 reach the costa, it is probably distinct from N. fcisthamcKi^ but is near 

 to N. restricta, Moore. N. feisthamcUi is one of the commonest 

 species occurring in Sikhim, and is found in all the months of the 

 year except the two or three coldest, and from 1,000 to 5,000 feet 

 elevation. It is found also in Western China, and has been defined 

 as a local race under the name of rcctifascia by Leech. 



606. NOTOCRYPTA EESTRICTA, MoorO. 



Colonel Swinhoe says this species is commoner in the Andaman 

 Isles than N. paralysos, Wood-Mason and de Niceville, and goes on 

 to say that the latter appears to him to be identical with N. fcis- 

 thamelii, omitting to notice the very distinctive white spotting of the 

 hindwing on the underside which makes N. paralysos unique in the 

 genus. N. rcsiricta in Sikhim is a very common species at low 

 elevations throughout the warm months. It is found also in Western 

 and Central China and in the Loochoo Islands. 



607. Udaspes folus, Cramer. 



Occurs in the low valleys commonly throughout the year. 



608. Baeacus septentrionum, Wood-Mason and de Niceville. 



A very rare species in Sikhim and obtained only by Mr. Otto 

 Mijller in the Terai. Mr. Dudgeon has a male taken in March, and 

 a female in August, both from a low elevation in Baling. 



609. Astictopterus olivascens, Moore. 



Also a Terai species, of which Mr. Otto MiJller obtained a few 

 specimens. The typical Sikhim form has the markings on the under- 

 side nearly obsolete. It occurs in Calcutta and is very common in 

 Burmah. It is variable, and one of these slight and inconstant 

 varieties has recently been named A. kada by Colonel Swinhoe. It 

 occurs right across China to Hainan island, and the " Cijclopides^'' 

 chineiisis of Leech, C. hcnrici of Holland, and " Steropis " nuhilus of 

 l^Iabille, are synonyms. 



610. Keeana diocles, Moore. 



Very common at low elevations from March to December, It is 

 widely spread, and is found in Sumatra and Java. 



611. Pirdana eudolphii, Elwes and de Niceville. 



I know of only two specimens of this very rare species from 

 Sikhim, both females, and one each in the collection of Colonel A. M. 

 Lang, R.E., and myself, the latter taken by Mr. J. Gammie. I have 

 both sexes from Java.
