MR. A. G. BUTLER ON THE BUTTERFLIES OF MALACCA. 
Family TIIERMESIIDJE. 
Genus Cottjza, Walker. 
1. Cottjza drepanoides, Walker, Lep. Het. xv. p. 1552 (1858). <$, Penang. 
Family URANIUM. 
Genus Nyctalemon, Dalman. 
1. Nyctalemon docile, n. sp. Allied to N. hector , from which it differs in its superior 
size, deeper and redder coloration, narrower central white hand, which is bordered 
internally by a broad brown band, and externally by a narrow one ; the costal border 
not spotted with white ; a broad oblique diffused discal brown baud : secondaries with 
the apical area much less streaked with black, the anal area much more streaked ; the 
marginal interrupted black border narrower ; the tails considerably longer and narrower 
towards their extremities. Expanse of wings S 5 inches G lines, ? 6 inches 4 lines. 
$ ? , Malacca (6 examples). This species is a well-marked local representative of 
N. hector. 
Family TJRAPTERIDiE. 
Genus TJrapteryx, Leach. 
1. TJrapteryx marginipennis, n. sp. Wings greyish brown, transversely streaked 
with clay-colour, and reticulated throughout with transverse dark-brown hatchings : 
primaries with the apex broadly, and the outer margin rather narrowly, nearly sulplmr- 
yellow ; costa whitish ; a yellow spot on the second median interspace : secondaries with 
the outer margin rather narrowly sulphur-yellow; two decreasing submarginal black 
dots above the angle of the wing : body greyish brown. Wings below grey, spot and 
borders paler than above, reticulations obsolete ; body below whitish. Expanse of wings 
2 inches, d, Malacca. 
This curious species is not nearly allied to any species with which I am acquainted ; 
it approaches most nearly to TJ. crocojjtei'ata ; but the wings are very slightly angulated. 
Family GEOMETRIDiE, Guenee. 
Genus Agathia, Guenee. 
1. Agathia discriminata. Walker, Lep. Ilet. xxii. p. 591 (1861). c?, Penang. 
Family ACIDALIIDiE. 
Genus Acid alia. 
1. Acidalia exclusa, ( Hemerophila ? exclusa) Walker, Cat. Lep. Ilet. xxi. p. 320 
(I860); Macaria ohstataria , Walker, l.c . xxiii. p.928 (1861). d, Malacca. Walker 
notes this species as Bremer’s Philohia cinerearia ; but, as I have no Chinese examples 
before me, I cannot certify the correctness of this determination.
