line from 4 / 5 of the costal margin obliquely outwards, apex striated brown. Below vein 5 a brown marginal 
spot. Hindwing yellow, dusted with rust-brown, without marking. 25 mm. Lombok. 
12. Genus: Chaetoceras Warr. 
Palpi short, antennae of $ strongly dentate, hind tibiae with 4 long spurs. Costal margin of forewing 
slightly incurved in the centre, apex somewhat produced. Distal margin excised from the apex to vein 4; at 
veins 4 and 3 slightly angular, below it excised. Hindwing rounded below the apex, anal angle pointed. Neu- 
ration of forewing: veins 5 and 6 + 7 from the upper cell-angle. Veins 8 + 9 + 10 and vein 11 arise far basad. 
Type: simplex Warr. 
Ch. simplex Warr. Fore wing lilac grey, lines claret-coloured, the interior line from y 3 of the costal 
margin, oblique, slightly bent, touching the black cellular spot; the exterior line from % of the costal margin 
partly interrupted, bent. Marginal line rusty red, fringe brownish-red. Hindwing with a red interior and exterior 
line. Cellular spot and marginal spot reddish. — f. diversipenmis Warr. greyer, lines less distinct. 22 mm. Amboina. 
Ch. casbiata Warr. Forewing ochreous or whitish grey. Cellular spot black, surrounded by dark. 
Interior line as a dark spot above and below the median vein. Exterior line composed of small brown spots 
from % of the costal margin parallel to the distal margin. Subapical spot black. Hindwing with a white cellular 
spot. Exterior line fine, obtusely angled at vein 4. At the anal angle a bluish, glossy spot edged with yellow. 
35 mm. New Guinea. 
Ch. parvidens Warr. Very similar to casbiata. Forewing reddish-grey. Lines marked by black spots. 
Cellular spot faded, 4 black spots at the apex distinct. Hindwing with a light cellular spot. The lines also only 
composed of dots. The exterior line with a double spot at the inner margin as in casbiata, but more remote 
from the distal margin. The spot below the lower dent plainly black, not glossy. Dents at veins 4, 6, 7 feeble. 
30—32 mm. New Guinea. 
Ch. strigulosata Warr. (58 f). Forewing bone-coloured, dusted with grey. Interior line only a spot in 
the submedian fold. Traces of a double brown exterior line beginning from vein 6. Cellular spot black, some 
dark submarginal spots. Hindwing less dusted grey. The double distal line angular at vein 4. Cross-vein 
and marginal line black. 30 mm. New Guinea. 
Ch. striolata Warr. (58 f). Lighter, larger than strigulosata, dusted with brownish. Interior line a brown 
spot in the submedian fold. Cellular spot large, black. Exterior line double, brown, distally lighter. 3 black 
submarginal spots at the apex. Hindwing whiter, the lines more distinct and browner than in strigulosata. 
32 mm. New Guinea. 
Ch. sulphurata Warr. (58 f). Yellowish-white, at the base grey. Interior line fine, pale brown, curved. 
Cellular spot in a pale yellow area. Exterior line broad, dark brown from % of the costal margin to vein 4, 
then incurved to the centre of the inner mai’gin. Behind it lilac grey, from the apex to the centre of the distal 
margin dark brown, marginal line yellow. Hindwing proximal half yellow with a brown line on the cross-vein. 
The broad distal band margined with black, sharply angled on vein 4. Distal margin lilac brown, before it 
lighter. At veins 4 and 7 large dents, at 6 a feeble dent. 25 mm. New Guinea. 
Ch. transnigrata Warr. (58 f). Similar to the two preceding species. Ground-colour greyer. Lines 
brown, more distinct, with black dots. Exterior line scarcely double. Apical spots large. In the hindwing the 
exterior line is surrounded at the angle at vein 4 by black shadows. 32 mm. New Guinea. 
Ch. candidaria Wkr. (58 f). White. Costal margin of forewing somewhat brownish. Interior line only 
a black cellular spot, exterior line marked by a spot behind it and near the inner margin. At the margin 
fine black dots. Hindwing with a black discal spot. A curved ochreous median and exterior line near the lower 
dent united there by another black spot. 30 mm. New Guinea. 
Ch. biplagiata Wkr. (58 g). Violettish-brown. The fore wing lacks the interior line, the exterior line is 
ochreous, inside bordered with dark, in the centre concave. Marginal line rusty yellow. Hindwing with a 
white costal-marginal area bordered by a black irregular line. 25 mm. Mysol. 
13. Genus: Cliaetopyga Wan. 
Forewing concave at the apex. Distal margin slightly dentate at veins 4, 6, 7, anal angle sharp. Inner 
margin curved, excised before the anal angle. Hindwing excised at the costal margin, dentate at veins 4, 6, 7, 
with a hair-pencil at the inner margin. Neuration as in Epiplema. Type: horrida Warr. 
Ch. horrida Warr. (58 f). Forewing reddish-brown. An indistinct dark basal line. Median band dark 
brown broad, in the middle narrower, margined with black ; a narrow dark marginal band from the apex to vein 4.
