MR. A. G. BUTLER ON THE BUTTERFLIES OF MALACCA. 543 



Genus Hypolimnas, Hiibner. 



1. Hypolimnas bolina, (Papilla bolina) Linnaeus, Mus. Lud. Ulr. p. 295 (1764).. 

 S ? , Penang. 



2. Hypolimnas incommoda, n. sp. S very similar to the male of H. bolina, but with 

 the subapical band of primaries straigkter on the underside, and the pale brown sub- 

 marginal spots narrower and darker ; expanse of wings 3 inches 1 line. ? differs from 

 the female of S. bolina in having a broad oblique subapical white band on the upperside 

 of primaries, a large diffused sordid white patch just beyond the cell of secondaries, and 

 the subrnarginal spots all separated, small, and pale brown : expanse of wings 3 inches 

 11 lines, c? $ , Malacca. 



This form seems to replace H. bolina in Malacca ; in some respects it approaches the 

 Javan species H. nerlna. 



Genus Cktkosia, Pabrieius. 



1. Cethosia methypsea, n, sp. Allied to C. hypsma and O. penthesilea : from the 

 former it differs in its smaller expanse, the regularity of the subapical oblique whitish 

 band of primaries, in the presence of an apical submarginal series of four whitish spots 

 connecting the lower extremity of this band with the costa, and in the much less pro- 

 minent angulation of the outer edge of the red band on the under surface of secondaries ; 

 from the latter it differs in its smaller expanse, much brighter coloration, the yellower 

 tint of the subapical band of primaries, the more irregular and much more broadly 

 white-bordered red band below ; the primaries are also more produced. Expanse of wings 

 2 inches 9 lines to 3 inches 3 lines, 3, Penang. The larger measurement is taken 

 from examples previously in the collection. We have a female from Assam. 



2. Cethosia hypsina, Pelder, Seise der Nov., Lep. iii. p. 385 (1867). c? ? , Malacca. 

 Also in the Museum collection from Nepal and Assam. 



Genus Cirbochboa, Doubleday. 



1. Cibbochboa obissa, Pelder, "Wien. ent. Monatschr. iv. p. 399 (1863) ; Reise der 

 Nov., Lep. iii. pi. 49. figs. 7. 8 (1867). <? ? , Malacca; Penang. 



2. Cibbochboa Johannes, Butler, P. Z. S. p. 221, pi. 17. fig. 10 (1868). 3 ?, Ma- 

 lacca. 



3. Cibbochboa bajadeta, Moore, Cat. Lep. E.I. C. i. p. 150, pi. 3a. fig. 3 (1857). 

 $ , Malacca. This seems to be Pelder's C. malaya. 



4. Cirbocheoa rotundata, n. sp. ? . Nearly allied to C. mlthila of Moore, the 

 wings more rounded, primaries less produced; markings of primaries above almost 

 obsolete ; outer undulated line of secondaries much more distinct ; below all the bands 

 and spots tawny instead of ochre yellow : expanse of wings 2 inches 11 lines. Malacca. 

 I have no doubt that this species is distinct from C. mlthila ; the coloration of the bands 

 below is strikingly different.
