E. perplexa Swh. (44 c). $ antennae, palpi, head, and apex of abdomen ochreous, thorax and forewing 
dark ochreous-brown, at the proximal margin a little before the middle is a black spot situate in an ochreous 
area and another one opposite it. Abdomen black. Hindwing blackish-brown, darker than forewing. All the 
fringes brown with some ochreous hairs. Wings beneath lighter with an ochreous margin, body and legs ochreous, 
too. Expanse of wings: 27 mm. Singapore. 
E. icelomorpha Swh. is allied with E. perplexa Swh. (44 c). $ irons white; palpi, antennae, thorax and 
forewings pale ochreous-yellow; forewing in the basal two thirds more brown, and with a median band being 
pale brown in the anterior half, white in the posterior half, and two dark purple double spots as well as two 
similarly coloured subapical single spots. Hindwing pale ochreous, but painted brown except in the marginal 
area. Abdomen blackish, with an ochreous anal brush. Legs whitish. Expanse of wings: 29% mm. Padang, 
West Sumatra. 
E. hemibathes Swh. $ palpi, antennae, head and anterior part of thorax light ochreous, the rest of 
the thorax, abdomen and wings dark ochreous-brown, hindwing somewhat lighter than fore wing. The latter 
with an ochreous costal line and ochreous narrow marginal band and broad apex. Hindwing with a pale straw- 
coloured costal and marginal band. Under surface almost white. Expanse of wings: 27 mm. Padang (West 
Sumatra). — hemibathoides form. nov. (44 e) from Kina Balu has an expanse ($) of 27 mm, the length of wings 
being 12 mm, the ground-colour of the wings is a brownish black, the hindwings are scarcely lighter than the 
forewings, the marginal band of the hindwing is scarcely lighter than that of the forewing, the under surface 
of the wings is but very little lighter than the upper surface. 
E. ridleyi Swh. $ and $ brown and ochreous. Forewing strewn with large black scales and with 
a jet-black discocellular spot, marginal area and fringes lighter. Hindwing black with a broad greyish-ochreous, 
ecpially broad marginal band. Abdomen black with a greyish-ochreous anal brush. Under surface whitish; 
forewing with a black discocellular spot, hindwing with a sharply marked black lunar spot, the basal and dorsal 
areas of the wings blackish. Expanse of wings: 46% mm. Singapore. 
E. fumosa Snell. (47 g). <$ bead and thorax dark brown. Forewing dark greyish-brown with a 
pale yellow marginal band, everywhere dusted black and with a large, black discocellular spot. Hindwing 
greyish-black with a light yellow marginal band, abdomen greyish-black with a yellow anus. 42 mm. ■— $ body 
and forewing brownish-grey, the latter with a jet-black, light-margined discocellular spot and close at this 
spot there are two light, parallel transverse lines feebly bent like an S. Hindwing lighter greyish-brown. 35 mm. 
Sumatra. 
E. rubiginosa Snell. (47 g). antennal combs brownish, palpi pale ochreous-yellow. Body above 
light ferruginous, and three quarters of the forewings, being otherwise ochreous-yellow, are provided with 
such a dusting. In this ferruginous area there are two lighter transverse lines being both forked three times. 
In the area 5 there is near the margin an oval, jet-black spot. Hindwing yellowish-white, towards the posterior 
margin liued ferruginous. Under surface uni-coloured yellowish-white. 20 mm. Java. 
E. flexuosa Veen from Java is also unknown to me from the literature on entomology. 
E. tonkinensis sp. nov. (44 f). A J from Haiphong (Tonkin) I hesitatingly describe as a new species; 
it resembles E. plana Wile., catala Swh. etc. — Forewing light ochreous-yellow with a round, jet-black disco¬ 
cellular spot, the diameter of which is more than 1 mm, and with a straight, equally broad, blurred band formed 
by brown scales, of about 2 mm width, extending from the middle of the posterior margin subparallel to the 
margin as far as vein 6, from where it is rectangularly broken and turned proximad and in front towards the 
costal margin, which it does not quite reach; the proximal side of the apex of the angle of this band is about 
equally distant from the discocellular spot and from the apex of the wing. The under surface of both 
wings and the upper surface of the hindwing are uni-coloured whitish-ochreous with similar fringes. Palpi 
below ochreous, above and on the sides brown. Head and thorax light ochreous, thoracal dorsum and antennal 
pinnae slightly brownish. Under surface and apex of abdomen ochreous (above and laterally the abdomen 
is rubbed off!). Eyes jet-black, finely reticulated lighter. Expanse of wings: 42 mm. Length of wings: 20% mm. 
E. catala Swh. (atomaria Wkr. 1855 (nom. praeocc.) Sn. 1877). Head, thorax, and forewings saffron- 
coloured (E) or ochreous ($), finely scaled black, in the E with turn indistinct ferruginous transverse stripes 
and an indistinct darker similar one. Discocellular spot jet-black. Hindwing much lighter than forewing, in 
the $ hued with a saffron-colour. Abdomen of $ light greyish-brown, of <$ ochreous. Under surface of $ light 
ochreous, of $ very pale. 42 to 44 mm. Java. -— • miilleri Sn. (43 f) is a form occurring in Java and Celebes being 
certainly wrongly mentioned in Swinhoe’s so-called ,,Revision“ as a synonym of catala, chiefly because the 
name miilleri was given in 1877, catala, however, only in 1903. It is larger: $ 45 to 47, $ 62 to 65 mm, wings 
ochreous-yellow or golden yellow (S) without any other markings except the black discocellular spot or ($)
