29. Genus: r^eueoblepsis gen. nov. 
Proboscis present; palpi very small, porrect; antennae in both "sexes bipectinate though shorter in 
the Hind tibiae of $ only with terminal spurs. On the forewing the costal margin is curved before the more 
or less produced apex; distal margin dentate at vein 4, above more or less deeply excised, below oblique. 
Hindwing with a rounded apex, anal angle angular, distal margin slightly curved (or with a small triangular 
tooth in the centre). In the forewing vein 6 mostly rises from the upper cell-angle, veins 7, 8 and 9, 10 being 
stalked, vein 8 and 9 anastomosing and forming an areola, vein 11 extending very close at 10, and in one case 
being stalked with it. Type: L. carneotincta Warr. 
L. carneotincta Warr. (48 k). Forewing at the base and along the costal margin to the distal line 
flesh-coloured ochreous; from the base an orange line below the subcostal to the distal line; the proximal and 
distal lines are brown, obliquely from the hind-margin parallel with the distal margin, the proximal line ending 
at the lower cell-angle, the distal line being slightly dentate, above recurved to the costa; between veins 2 
and 3 an angular hyaline spot, a smaller triangular spot above vein 3; marginal area dark brownish, traversed 
by a white subterminal zigzag line; the extreme distal margin from the apex to the centre whitish; fringes 
light, below the middle turning browner. Hindwing white, the lines rusty grey, the proximal line straight, 
the distal line bending off from it above the middle; behind the subterminal line a grey band. Beneath the 
forewing is dark brownish grey and exhibits all the markings; hindwing white with a broad dark median band 
showing through above, and with a narrow subterminal band. Described from a single $ from Bukau (Sarawak). 
The hindwing is not dentate in the centre, and it can therefore not be identical with excisa Hmps.\ it is more 
closely allied to neorna Swh. from Singapore. 
L. neoma Swh. Forewing white, in some places suffused with light chestnut speckles. Two almost 
straight brown lines from the posterior margin of the hindwing extend parallel through both wings, being suddenly 
convergent at vein 5 of the forewing, then running as a single line to the costal margin near its apex. Between 
them there is on the fore wing a large hyaline spot; the rest of the wing is coated with a light colour, at the 
distal margin there is a very broad band of light flesh-coloured spots; marginal line brown; fringes light flesh- 
coloured. radiated with brown. Hindwing in the proximal area almost white, distal-marginal area behind the 
distal line suffused with dark; through the centre of the disc a dentate white line. Under surface white, the 
hyaline spot in the forewing prominent, outside bordered by a dark brown band; hindwing with a broad dark 
brown band occupying a third of the wing. Described from a G from Singapore (Malay Peninsula). 
L. fristis Swh. (= renifera Warr.) (48 k). Forewing white, with a broad dark brownish-grey median 
band from before the centre of the hind-margin to the upper cell-angle; a similar band at the distal margin 
from the anal angle to vein 6, traversed by a white dentate subterminal line. On the hindwing the bands are 
duller; on the median band on both wings there are a few markings of small white iridescent raised scales. 
Beneath as above. The type of tristis originates from Matang Road (Borneo) and is a (J, the type of renifera 
Warr. from Gunong Ljau (Malay Peninsula) is a $. 
L. excisa limps. (48 k) is larger than carneotincta Warr., the excision in the margin of the forewing 
is deeper; the flesh-coloured costal area is broader and more intense; in the hindwing the distal line is straight, 
but divergent, the space between it and the proximal line is more intensely grey; the distal margin with a strong 
dent in the centre. Naga and Khasia Hills in Assam. 
L. fenestraria Mr. (48 k as fluestraria) . Forewing whitish, in some places coated with greyish; 2 distantly 
separated undulating brown lines from the hind-margin of the hindwing to the costa of the forewing before 
the apex, between which there is on the forewing a transparent spot from vein 2 to 5; a subterminal row of 
small white crescents, distally convex, and at the distal margin a row of proximally concave ones; marginal 
line brown. Sometimes the wings are coated with a light greyish ochreous colour as in the specimen described 
by Hampson, but such specimens are exceptional. North India. 
L. ostia Swh. resembles fenestraria, also in its size, but it is invariably lighter, without grey or ochreous 
shades; the whitish hyaline spot in the fore wing is prolonged above vein 5 into the upper and apical portion 
of the wing. Described from the Malay Peninsula. 
30. Genus: DitrigOBisi Mr. 
Proboscis present; palpi very small; antennae in the G bipectinate; middle tibiae with 1 pair, hind 
tibiae with two pairs of spurs; fore wing with a sharp but not produced apex; distal margin almost straight; 
anal angle of hindwing produced to a short, obtuse tail; veins 6. 7. 8, 9 of fore wing stalked, 8, 9 anastomosing 
with 10 and forming an areola; hindwing with a short cell. Type: D. triangularia Mr. 
D. triangularia Mr. (48 k). Diaphanous white, costa of forewing ochreous. Forewing with 5, hindwing 
with 4 ashy grey lines; on the tail of the hindwing a black spot above which the 3 distal lines flow together. 
Fringes of both wings dark brown. Sikkim.
