MR. A. G. BUTLER ON THE BUTTERFLIES OF MALACCA. 
513 
Genus IIypolihnas, Iliibner. 
1. Hypolimnas bolina, (Papilio bolina) Linnaeus, Mus. Lud. Ulr. p. 295 (1764). 
cf ? , Penang. 
2. IIypolimnas incommoda, n. sp. d very similar to the male of H . bolina , but with 
the subapical band of primaries straighter 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 U. 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 submarginal spots all separated, small, and pale brown : expanse of wings 3 inches 
11 lines. $ ? , Malacca. 
This form seems to replace U. bolina in Malacca ; in some respects it approaches the 
Javan species II. nerina. 
Genus Cetiiosia, Pabricius. 
1. Cetiiosia methypsea, n. sp. Allied to C. hypsina and C. pent lies ilea : 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, ff, Penang. The larger measurement is taken 
from examples previously in the collection. We have a female from Assam. 
2. Cethosia hypsina, Eelder, Reise der Nov., Lep. iii. p. 385 (1867). S ?, Malacca. 
Also in the Museum collection from Nepal and Assam. 
Genus Cirrochroa, Doubleday. 
1. Cirrochroa orissa, Eelder, Wien. ent. Monatschr. iv. p‘. 399 (1863) ; Reise der 
Nov., Lep. iii. pi. 49. figs. 7. 8 (1867). S $, Malacca; Penang. 
2. Cirrociiroa Johannes, Butler, P. Z. S. p. 221, pi. 17. fig. 10 (1868). 6 ?, Ma- 
lacca. 
3. Cirrochroa bajadeta, Moore, Cat. Lep. E.I. C. i. p. 150, pi. 3 a. fig. 3 (1857). 
? , Malacca. This seems to be Eelder’s C. malaya . 
4. Cirrochroa rotund ata, n. sp. ? . Nearly allied to C. mithila 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. mithila ; the coloration of the bands 
below is strikingly different.
