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



Family THERMESIID^l. 

 Genus Cotttza, "Walker. 

 1. Cotitza drepanoides, "Walker, Lep. Het. xv. p. 1552 (1858). 6 , Penang. 



Family URANILDiE. 



Genus Nyctalemon, Lalman. 



1. Ntctalemon docile, n. sp. Allied to iV. 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 hrown band : 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 6 lines, ? 6 inches 4 lines. 

 S ? , Malacca (6 examples). This species is a well-marked local representative of 

 2V. hector. 



Family URAPTERIEvE. 



Genus TJraptebyx, Leach. 



1. TJeapteryx marginipennis, n. sp. Wings greyish hrown, 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 sulphur- 

 yellow ; costa whitish ; a yellow spot on the second median interspace : secondaries with 

 the outer margin rather narrowly sulphur-yellow; two decreasing suhmarginal 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. <?, Malacca. 



This curious species is not nearly allied to any species with which I am acquainted ; 

 it approaches most nearly to TJ. crocopterata ; but the wings are very slightly angulated. 



Family GEOMETRIDiE, Guenee. 

 Genus Agathia, Guenee. 

 1. Agathia discriminata, Walker, Lep. Het. xxii. p. 591 (1861). <$ , Penang. 



Family ACIDALIID^E. 



Genus Acid alia. 



1. Acidalia excltjsa, ( Hemerophila ? exclusa) Walker, Cat. Lep. Het. xxi. p. 320 

 (1860); Macaria obstataria, Walker, I.e. xxiii. p. 928 (1861). <?, Malacca. Walker 

 notes this species as Bremer's Philobia cinerearia ; but, as I have no Chinese examples 

 "before me, I cannot certify the correctness of this determination.
