L. obliquilinea Hmps. (= thibetaria Pouj.) (48 c) differs from nivea and idaeoides in the first pair of 
lines extending extremely obliquely, beginning near the apex and being almost straight; the 3 distal lines as 
in idaeoides , but almost straight. Sikkim and Naga. Hills in Assam, mentioned by Leech also from Chang- 
Yang and I-Chang in West and Central China. Pottiade’s thibetaria originates from Moupm. 
L. furvicosta Hmps. (48 c) is quite similar to Peridrepana fulvicosta Dudg., but the antennae are 
thickened by densely appressed scales, instead of being bipectinate; the forewings are apparently considerably 
narrower. 
10. Genus: Ectothyris Swh. 
Proboscis present, palpi stout, porrect, slightly upturned at the end; last joint small; antennae thickened, 
with appressed serrate dents; middle tibiae with one pair of spurs, hind tibiae with two pairs; fore wing long; 
costa at the. base bent, then straight, apex obtuse; distal margin oblique, slightly gnawed out below' vein 3; 
hindwing with a dent on the veins 6 and 3, and an obtuse roundish projection behind vein 4, 5 with an indentation 
on each side; anal angle from vein 1 to 3 truncate; forewing with a non-angular discocellular; vein 6 from 
the flattened end of the subcostal; veins 7, 8, 9 forked, 10, 11 forked, 10 anastomosing with 8, 9 and forming 
an areola, veins 7 and 11 from this areola, 10 far behind 11. Type: E. trijenestrata Sivh. 
E. trifenestrata Swh. ( = quaclrangulus-$ Sivh.) (48 d). Forewing light greyish-ochreous; the veins 
are partly marked with brown; lines brown, double; the proximal line curved, before it a light space; the distal 
line obliquely outward as far as vein 6 where it is angular and obliquely inward, filled with light, the lower 
cell-end and the areas between the base of vein 2 and that of 5 hyaline, the veins wherever they cross these 
areas grey, marked with tiny black dots; subterminal line of small crescents, light, distally bordered with 
dark; hindwing similar. Under surface light fawn-coloured, with dark subterminal bands, the vitreous spots 
very iridescent. Described from Pulo Laut (North Borneo); a $ in the Tring Museum from Sandakan; also in 
the Coll, of the British Museum from Coping, Perak. 
E. semisecta Hmps. Pore wing light ochreous, powdered with light brown, with brown lines, the 
proximal and middle one being indistinct, angular in the centre of the wing, and marked with blackish vein- 
spots; the distal line oblique, curved, likewise marked with dark vein-spots; anal' a^gle filled with a darker 
brown, containing a round light spot; subterminal line indistinct; from the cell-end to the distal margin a brown 
streak below the apex; 2 tiny black dots on the discocellular. Hindwing much browner, with a straight double 
proximal and distal brown line and 2 rows of dark dots between them; subterminal line light, undulating, 
bordered with dark brown; all the dark and light transverse lines are visible on the abdominal dorsum. Type 
in the British Museum, a from Sarawak (Borneo). Distinguished from the typical species by the absence 
of hyaline spots. 
11. Genus: Strcpslgonia Warr. 
Proboscis narrow, palpi short, delicate; antennae in both sexes bipectinate, the dents in the $ shorter, 
those on the inside shorter in both sexes than those on the outside; middle and hind tibiae with one pair of 
spurs; forewing with a produced apex, the margin below it gnawed out and between veins 3 and 4 angular, 
then oblique; on the hindwing the hind-margin is prolonged, the margin between veins 3 and 4 produced; 
on the forewing vein 6 rises from the upper cell-end or on a short stalk with 7, 8; 9, 10, 11 forked, 11 and 
6 shortly separated, 7 and 10 rise near the end of the areola, 8, 9 anastomosing and forming an areola. 
Type: S. nigrimaculata Warr. 
S. nigrimaculata Warr. (48 d). Forewing dull reddish-brown, with an indistinct marking; the proximal 
and distal lines in the centre of the wing nearing each other, irregularly curved and dentate, the space between 
them feebly darker, particularly at the costa; on the discocellular 2 very small black dots; subterminal line 
forming small crescents, dentate, with a dark spot above vein 6 towards the apex; fringes above the angle 
blackish, with light rays behind the ends of the veins; costa towards apex with 2 dark spots. Hindwing with 
a light costal area without markings; the median band encloses an oblong black spot at the hind-margin; 
at the lower cell-angle a black dot. Under surface lighter; distal line thick and black, angular on the 
forewing, curved on the hindwing; cell of forewing brownish. Described from a single from Gunong-ljau, 
Perak (Malay Peninsula). In this species the angle of the distal margin at vein 3 is feeble on both wings. 
S. placida Swh. (48 cl). Forewing olive-grey with dark olive markings; lines finely darker; the proximal 
line projects above and below the median and extends obliquely proximad; distal line forming small crescents,
