which he caught himself in a forest near the Saentis Estate, not more 
than two miles from the sea. 
101. Elymnias ( Bruasa ) abrisa, Distant. 
Very rare in the high forest near Selesseli in July and at Namoe 
Oekor. Both sexes are described by Mr. Distant, and the male is 
figured. We have seen only seven female specimens. But for the fact 
that Mr. Distant describes the male, we would certainly have considered 
this species to be a dimorphic form of the female of E . swmatrana , 
Wallace. 
102. Elymnias ( Agrusia ) esacoides, de Niceville. 
Dyctis esacoides , de Niceville, Journ. Bomb. Nat. Hist. Soc., vol. vii, p. 323, n. 2, 
pi. H, fig. 2, male (1892). 
Exceedingly rare, three specimens only have been obtained, one in 
the forest near Selesseli in July, two from the lower hills. All the 
rarer species of Elymnias have a soft weak flight and settle often with 
folded wings. They are very fond of shadowy spots and of rest, and 
once settled they remain for a long time, leaving their resting places 
only when frightened or driven aw r ay. As they all rest with shut wings 
they are in this position much less conspicuous than when on the wing. 
Subfamily Amathusiin^;. 
103. Zeuxidia amethystus, Butler. 
Hagen. Kirby. Butler. Distant. Staudinger. Rare; found only 
in dense virgin forests like all the rest of the genus not at a lower eleva¬ 
tion than Bekantschan in September. It occurs higher in the hills than 
any other Zeuxidia. The female has the macular band on the upperside 
of the forewing ochreous-white. 
104. Zeuxidia nicevillei, Fruhstorfer. 
Z. nicdvillei, Fruhstorfer, Ent. Naoh., vol. xxi, p. 196 (1895). 
Fruhstorfer. Described as being a local form of Z. doubledaii , 
Westwood. The latter was described from a female specimen from 
“India,” and is somewhat roughly figured in the Genera of Diurn. Lep. 
on pi. lii, fig. 1. Distant figures both sexes and records it from Penan o- 
and Perak. Moore records it from Penang. I have compared both 
sexes from Perak with both sexes from Sumatra, and Sumatra females 
with Hewitson’s original figure, and can discover no differences what¬ 
ever. Herr Fruhstorfer has recently been to London and has probably 
compared his types of Z. nicevillei with the type of Z. doubledaii , so
