line double, angular on vein 6, then obliquely inwards, undulated; behind it a third line; the latter two extend 
as a dark shadow into the apex; before the margin a light undulated line with black lunular spots between 
the veins; the whole median area is dark below the centre. Hindwing with an inner and an outer band of 
undulated lines; subterminal line and cellular dots as in the forewing, tinder surface light grey, all the lines 
darker. Face and forelegs black; vertex snow-white; thorax and abdominal dorsum like the wings. $ feebly 
lighter than the Khasia Mts. 
37. Genus: Monoprista gen. non. 
It differs from Leucodrepana (p. 449) in vein 6 of forewing rising from the upper cell-angle. Of 
a stouter structure; colouring olive-brown; the outer line not undulated. Type: M. nudobia Swh. 
M. nudobia Swh. (50 d). Forewing olive-brown, partly with a yellowish tint; 2 black dots at the two 
cell-angles; in the forewing the cell and a subcostal streak are darker; 3 dark oblique lines from the apex, the 
two inner ones of which form a narrow band expanding at the centre of the inner margin; behind the third 
follows a dark marginal band being broader at the inner margin. In the hindwing the basal area is dark, then 
follows a yellowish band; the dark band, outer line and marginal area as in forewing. Under surface grey with 
3 grey distal lines. Khasia Mts. » 
38. Genus : Spfca Swh. 
Proboscis present; palpi obliquely upturned, 2nd joint well scaled; antennae of $ .short, serrate-dentate. 
Middle tibiae with 1. hind tibiae with 2 pairs of spurs; Fore wing elongate with an obtuse apex and a smooth 
curved distal margin; veins 7, 8, and 9, 10 of forewing stalked, 8 and 9 anastomosing and forming an areola, 
divergent at their ends. Type: S. luteola. Swh. 
S. luteola Swh. (50 d). Forewing yellow with rosy-orange irroration. Lines rusty red, the inner line 
centrally angular, the middle line straight, the outer line curved, met by an oblique streak from the apex. 
Reniform macula surrounded by orange. Hindwing paler yellow. Sikkim. 
39. Genus: Tliymistada Wkr. 
Proboscis present; palpi delicate, upturned, reaching the vertex; antennae bipectinate, the dents in 
the <$ longer; middle tibiae with 1. hind tibiae with 2 pairs of spurs. On the fore wing the apex is bent 
down and produced, sickle-shaped; margin on vein 3 angular, above indented, below slanted off. Hindwing 
with a rounded apex and almost straight margin as far as vein 4, here dentate, the anal margin above the 
anal angle with a concavity into which veins 1 and 2 extend, whereby the anal angle appears to be lobate. 
In the forewing veins 6. 7, 8 are stalked, 9. 10 also stalked, 8 and 9 anastomosing and forming an areola. Type: 
T. tripunctata Wkr. 
Th. tripunctata Wkr. (= cervinaria Mr.) (50 b). Forewing of dark violettish-brown, of $ lighter 
and brownish; dark inner, outer, and subterminal lines in fresh specimens with small grey scales at their distal 
borders; on the discocellular 3 dark spots. Fringes black, at the tips light. Hindwing lighter, a dark spot at 
the anal angle with a broken line of small white scales on it. Sikkim. 
Th. undiiineata sp. nov. (50b). Forewing drab, traversed by dark grey, waved lines; 2 of them being 
indistinct through the basal area; inner line obliquely outwards, incurved below the centre; outer line above 
excurved, below the centre incurved, approaching the inner line on the submedian fold; the space between 
them rather much darker with a small black dot at each end of the discocellular; 3 undulating lines behind 
it. the first on a lighter band, the outermost bordered by the light subterminal line which proceeds from a light 
costal dot; before the dark brown fringe a distinct light line; hindwing grey, towards the margin darker; at 
the anal margin and before the concavity spots of small black scales. Under surface monotonously light grey; 
head, thorax, and abdomen drab. Khasia Hills (Assam). Type in the Tring Museum. — The concavity in the 
forewing is low in both sexes. 
Tli. nigritincta sp. nov. (50 b). Forewing sand-coloured grey, traversed by darker dentate lines. 
This ground-colour is only shown in the distal half of the wing; basal half, costal area, and marginal area 
filled up with blackish ; the lines along the costa] margin intensified by oblique glossy stripes, the subterminal 
line of small glossy scaled dents at the costal margin and inner margin; discal spot oblique, blackish; fringes 
behind a fine light line blackish. Hindwing dark grey, more violet and marked with small silvery scales towards 
the anal angle. Fringes from the apex to vein 3 yellowish grey, then with a black line bending round into the
