9. Elymnias penanga. 



Melanitis penanga, Westw. Gen. Diurn, Lep. p. 405. 

 {nee Hewitson). 



Hab. — Penang (B. M., type) . 



10. Elymnias sumatrana. 



Melanitis penanga, He wits. Ex. Butt. iii. pi. li. f. 1, 4. 

 (nee Westwood.) 



Hah. — Sumatra (Coll. "Wall., type). 



This species is remarkably like M. penanga, but as the 

 conspicuous golden-yellow spot on the costal margin of 

 the hind-wings (underside) is entirely absent, and as it 

 also differs in the white patch on the hind-wings above, 

 and in their somewhat more angular outline, I feel com- 

 pelled to separate it. 



11. Elymnias Lais. 



Papilio Lais, Cram. 110. A. B.; Fabr. Ent. Syst. iii. 

 pt. i. p. 58; Biblis Lais, Godt. Enc. Meth. ix. 326; 

 Melanitis Lais, Doub. West. & Hew. Gen. Diurn. Lep.; 

 Elymnias Lais, Moore, Cat. Lep. E. I. C. p. 237. 



Hah. — Sumatra (Wall. cJ • ? Oj Java, Borneo (B. M. 

 <^. ?). 



The Java specimens (Cramer*s types) agree very 

 closely with those of Sumatra and Borneo in the males. 

 The female is paler and yellower in colour, and rather 

 larger. A female from Sumatra, collected by myself, 

 difiers considerably ; the markings are much less distinct, 

 of a pale yellowish colour, except at the apex, where 

 they are bluish; and the ground colour is rich brown. 

 This specimen, to some extent, connects this species 

 with E. Casiphone. 



12. Elymnias Casiphone. 



Elymnias Casiphone, Hiibn. Samm. Exot. Schmett. iii. 



pi. 18 ? 



m&.— Java (Coll. Wall., B. M. c?) . 



A species closely allied to E. Lais, but of very different 

 colouration.
