dentate, as far as vein 6 obliquely distally, then proximad; subterminal line undulating, light, forming a feebly 
lustrous crescent in the anal angle; at the costa above and below the hind-margin a darker cloud; marginal 
line dark; above the lower cell-angle a black dot; hindwing similar, with 2 black cliscal dots. Under surface 
monotonously lustrous grey, on the forewing darker. The type, a $, originates from Sandakan in Borneo; 
another $ from Padang-Rengas (Malay Peninsula) is in the Tring Museum. In this species the dent of the 
'hindwing is distinct and that on the fore wing well marked, the indentation above and below it deep; vein 6 
on the forewdng conies from the upper cell-angle. 
S. affinis Warr. (48 d). Forewing greyish-ochreous, tinted with pink. Lines finely darker; the affinis. 
proximal and distal lines nearing each other in the centre of the wing, the distal line obliquely distally as far 
as vein 4, then proximad; the space between them dark with a yellowish-red tint; subterminal line of small 
crescents, light, between darker clouds; fringes at the indentations below a light terminal line dark; on each 
side of the discocellular a black spot. Hindwing similar; under surface white, the distal line thick and black, 
on the forewing angular, on the hindwing curved; upper half of forewing arched brownish. Described from a 
$ from Padang-Rengas on the Malay Peninsula. In this species the angle at the distal margin of both wings 
is strong, particularly on the hindwing. 
S. pustularia Wkr. Forewing whitish, subhyaline, the markings greenish-brown; at the hind-margin pustularia. 
before the centre 2 curved dark spots and a small one along the base of vein 2; discocellular light, before and 
behind it dark spots, the latter spot enclosing a white spot; distal line black, irregularly undulated; anal angle 
filled with dark; before the margin a chain of small crescents behind wdiich there are dark marginal spots on 
both the folds. Hindwing with a dark spot at the cell-end and 2 oblique streaks below the cell as far as the 
hind-margin; the distal-marginal half of the wing is dark, crossed by a light subterminal line and lengthways 
crossed by the light lines. The type, a $, from Sarawak (Borneo). Forewing obtusely angled at the end of 
vein 3, and hindwing on vein 4 stronger; antennae pectinate. I place it provisionally to Strepsigonia. 
12. Genus; Mjalospectra Warr. 
Proboscis present; palpi very short; antennae in both sexes bipectinate, in the ^ shorter; middle and 
hind tibiae with a single pair of spurs. Fore wing broadly hyaline; costal margin curved, with a flat, obtusely 
rounded apex; distal margin curved, below the centre crooked; hindwing with a distinct though obtuse angle 
on vein 4; cell of forewing longer than half the wing; the upper and lower thirds of the discocellular vertical, 
the centre oblique; the 1st and 2nd median branches at the base bent downward; vein 5 from the lower 
angle of the discocellular; 6 forked with 7, 8, 9 from the flattened end of the subcostal; 10 and 11 from the cell 
close together, 8, 9 anastomosing with 10 and forming an areola, 10 separated close before the costa. Type: 
H. grisea Warr. 
H. grisea Warr. (48 d). Forewing hyaline; basal area, costal area above the subcostal, and the marginal grisea. 
area clothed with scanty grey scales; proximal line dark, bordered vdth light, formed of crescents, on the veins 
distally dentate; in the grey marginal area a subterminal dark, dentate line of crescents extending from % 
of the costa and below the centre bordering on the hyaline spot. Between veins 3 and 4 a round marginal hyaline 
spot; marginal area below the apex subhyaline; marginal line dark, on the veins spotted; fringes light grey. 
Hindwing grey, the base, an angular postmedian band, and the marginal spot hyaline; beneath the hyaline 
spots are larger. Described from 2 $$ from the Angabunga River in British New Guinea; also from Biagi, 
Mambare River. The G differs in all the grey places being rust-coloured on both wings, the projecting angle 
in the distal band of the hindwing being filled with black on vein 3. 
H. arizana Wil. Wings hyaline with traces of grey transverse lines; at the distal margin some grey arizana. 
clouds; marginal line greyish, pierced by the whitish veins. 30 mm. Described from a single $ from Arizan 
(Formosa). 
H. diaphana sp. nov. (48 e) differs from grisea in the narrower dark markings being dull light grey diaphana. 
and insignificant; the proximal grey band is quite thin and instead of the broad distal band there are two narrow 
bands; one, the distal band, dentate, the other near the margin interrupted by the light spot between veins 
3 and 4. The hindwing shows similar differences. 1 $ from Mt. Goliath in Central New Guinea, at an altitude 
of 5 to 7000 ft. Found in February 1911 by A. S. Meek. 
H. hyalinata Mr. Forewing hyaline, basal area with few small rusty yellow scales; an antemedian hyalinata. 
rusty red band, bordered by the proximal and distal lines, and angular at the lower cell-encl; before the distal 
margin a dark rusty red band surrounded by black, distally angular above vein 6 and sharply proximally angled 
below vein 6, then distally almost to the margin near vein 4 and terminating in the anal angle. Marginal line 
and veins rusty red, on the hindwing the subterminal band is more regularly bent; along the hind-margin a 
few small rusty red scales. Thorax and abdomen grey, with a rusty red tint. 32 mm. North India; Penjab, 
Khasia Hills in Assam, Sikkim.
