418 Elwes & de ISTiceville — List of the Lepidopterous [No. 5, 



mineus) also. It has nothing to do with the following, Mr. de Niceville 

 has lately bred the latter ; it differs widely in the larval stage from 

 M. mineus. 



Mycalesis (Cahjsisme) perseus, Fabricius. 



Papilio perseus, Fabricius, Syst. Ent., p. 488, n. 199 (1775). 



Mycalesis perseus, Moore, Proc. Zool. Soc. Lond., 1878, p. 825. 



Papilio Uasius, Fabricius, Ent. Syst., SuppL, p. 426, n. 488-9 (1798). 



Mycalesis hlasius, Moore, Proc. Zool. Soc. Lond., 1878, p. 825. 

 Mr. de Niceville having bred ab ovo these two hitherto supposed 

 distinct species the one from the other, the former representing the dry- 

 season, and the latter the wet-season form, we have placed them together 

 under the older name, they were kept separate by Mr. Moore in his 

 Tenasserim paper. 



*20. Mycalesis anaxioides. 



M. anaxioides, Marshall, Butt, of India, vol. i, p. 107, n. 87 (1883). 

 ? M. anaxias, Moore, Proc. Zool. Soc. Lond., 1878, p. 825. 

 A single male from Tavoy of this very distinct species. 



*21. Mycalesis (Orsotricena) runeka. 

 M. runeJca, Moore, Horsfield and Moore, Cat. Lep. Mus. E. I. C, vol. i, p. 234, n. 

 501 (1857). 



Both sexes from Tavoy. The rains generation of this species is 

 probably M. medus, Fabricius, and was not obtained. 



*22. Mycalesis (Gulapa) mnasicles. 



M. mnasicles, Hewitson, Ex. Butt., vol. iii, Mycalesis pi. v, figs. 32, 33, male 

 (1864). 



One male from Tavoy rather smaller than Sumatran specimens in 

 the British Museum compared by Mr. Elwes. 



23. Mycalesis (Loesa) fervida. 



Loesa fervidtty Butler, Ann. and Mag. of Nat. Hist., fifth series, vol. x, p. 372, 

 n. 1 (1882). 



Mycalesis surJcha, Marshall, Journ. A. S. B., vol. li, pt. 2, p. 37, n. 1, pi. iv, fig. 1, 

 male (1882). 



Three males from Tavoy and one from Ponsekai which agree with 

 the types of this species in the British Museum, and Indian Museum, 

 Calcutta. 



Ypthima PHILOMELA, Johanssen. 

 Tphthima haldus, Moore, Proc. Zool. Soc. Lond., 1878, p. 825. 



Ypthima methora. 



Tphthima methora, Moore (nee Hewitson), Proc. Zool. Soc. Lond., 1878, p. 825. 

 The two above-mentioned species are probably different generations 

 of the ubiquitous Y. philomela. The true Y. metlwra is a very distinct
