62. Genus: Ketion Nic. 
This genus is established for a species separated from all its allies by a row of transparent spots 
in the hindwing, the position of which is similar as in certain Parnara ( guttata etc.), i. e. right across the 
centre of the hindwing. 
E. elia Heiv., from Sumatra, is said to differ from the figured form eburus, Plotz (= ayankara Fruhst.) 
(175 h) from Malacca in the narrower white median band of the hindwing: but apparently this band also differs 
in Malaccan specimens. The under surface of the figured G rather exactly corresponds to Plotz’s figure 
according to a Malaccan specimen, but the white of the anal-marginal portion of the hindwing above is 
immediately adjoining to the transverse row of hyaline spots. — In magniplaga Fruhst., from the Kina-Balu 
n Borneo, the spots of the forewing are much larger, the hyaline spots of the hindwing narrower. — The 
pecies occurs in single specimens and is not common. 
63. Genus: Creteus Nic. 
Only separable from the preceding genera by the $ stigma which consists of a scent-scale stripe along 
the middle third of vein 2. But one species. 
C. cyrina Hew. (= parca Nic., meleagrina Stgr. i. 1.) resembles the preceding species, but is easily 
discernible by the position of the hyaline spots of the hindwing: one in the cell-end, two above it and two 
below it. In Borneo-specimens the spots seem to be generally smaller. Khasia Hills and from the Kina-Balu 
(Borneo). 
64. Genus: Hidari Dist. 
This genus contains 4 rather similar forms, large lepidoptera of a dark brown ground-colour with a 
few large, transparent honey-coloured spots on the fore wing. Their exterior is somewhat like that of the species 
of the genera Erionota (p. 1070) and Gangara (p. 1071), from which, however, they are at once discernible by 
the structure of the imagines and by the larvae and pupae. Like the lepidoptera of the preceding genera, 
they have green larvae and brown pupae, whereas in the former genera they are white, with wax-like 
excrescences or covered with thin, brittle pubescence. The imagines, however, are nocturnal like Erionota 
thrax, beginning to swarm only after dusk and coming to the lantern like the Heterocera. 
H. irava Mr. (175 h). Above dark brown with 4 typically arranged discal hyaline spots, 1 in the 
cell, 1 below it in the .submedian area, 1 between the median sbranches, and 1 upwards and outwards from the 
latter; besides there is also often a very diminutive subapical pot. The under surface is lighter, more reddish 
greyish-brown, and often exhibits, particularly in the several small, very indistinct spots being scattered 
in the disc. — The larva is dull leaf-coloured green with some dark longitudinal stripes and a brown, darker 
marked head; between spun leaves of various palms, particularly Cocos and sago-palms; it changes into a 
brown pupa with a dark lateral line in which the cover of the proboscis does not reach to the abdominal end. 
The imagines fly in the evening, whilst in daytime they rest in bamboo-thickets and the crowns of palms. 
Malacca, Sumatra, Java, Bali, nearly everywhere common. 
H. doesoena Mart., from Sumatra, only differs in the hyaline spot between the median branches 
reaching to the spot in the cell, from which it is only separated by the lower cell-wall, and in the small 
spot in the cell of the hindwing beneath being white instead of yellow. 
H. staudingeri Dist. (175 h). The 4 spots of the forewing are confluent, forming a hyaline ochreous 
continuous band only crossed by the veins. Before the apex there appear yet- 2 small yellow punctiform spots. 
From Perak. 
H. bhawani Nic. (175 g, h) resembles irava, but the hindwing beneath is marked with numerous 
coarse brown transverse striae and exhibits a brown ray next- to the costa and anal margin. From the Arrakan 
Coast in Burma.
