L. pachycera limps. (86 a). 3 forewing greyish-brown, with a white crenulate transverse line which 
is mostly only distinct and widened on the anterior edge of the cell and on vein 12, a black streak at the lower 
cell-end and a dark strongly curved transverse line bordered with whitish outside towards the costal margin 
and extending from the costal margin before the apex to the tornus. Margin somewhat whitish at the apex, 
blackish above the tornus. Hindwing grey. $ more reddish-ochreous, with indistinct markings. Expanse of 
wings: 20—22 mm. Khasis, April till June, and October, rare. 
L. hel sp. n. (86 a). Body white, brownish at the end. Forewing lustrous white in the basal half, the 
marginal half brown, border-line between them somewhat crenulate. The marginal half contains a whitish 
postmedian line which is strongly bent distally, incurved below the cell; it is partly bordered with a darker 
colour almost forming spots; the marginal area behind it is more grey, with a dark brown spot at the mouth 
of 2. Fringe grey, dark brown towards the tornus. Hindwing light grey. Expanse of wings: 13 mm. Ivwang- 
tung, in July. 3 type from Liuping (State Museum Berlin). 
7. Genus: UTarosa Wkr. (incl. Atosia Sn.) 
Palpi bent up to vertex, antennae plain in both sexes. Hind tibiae with 2 pair of spurs. 7 of forewing 
stalked with 8 -j- 9, 10 with the latter from the same place or stalked, 11 bent towards 12. 6 + 7 of hindwing 
from the same place or stalked, 8 connected with the cell only near the base of it. — I have had no access 
to the description of N. nitobei Shir. 
N. conspersa Wkr. (= velutina Wkr.) (86 a). Body whitish, with red-brown spots. Forewing yellowish- 
white, with red-brown oblique spots and streaks which are mostly more distinct at the inner margin, especially 
distinct an inner-marginal spot at the base. Hindwing pale yellow. Expanse of wings: 22 mm. — Larva: oval, 
bare, transversely ribbed, green with white subdorsal lines, and white sublateral dots, legs yellow. Cocoon 
oval, whitish, with a brown spot at the end. India, Ceylon, Borneo. 
N. concinna Swh. (86 b) is very similar to conspersa, separated by the following marks: a distinctly 
whitish transverse line extends at % of the forewing, strongly projecting in the middle towards the base and 
defining a broad brown band in the costal-marginal half, but only little dentate above the inner margin. The 
light ground-colour is less prominent. Expanse of wings: 22—24 mm. Borneo, common. 
N. corusca Wil. (86 b) is very much like concinna, likewise with a strongly incurved whitish postmedian 
line, but without the conspicuous brown spot at the base of the inner margin; on the inside of the postmedian 
line there are places with blackish scales. Formosa, South China (Kwangtung), April and June till August. 
Expanse of wings: 22 mm. 
N. ersdodonfa Hmps. (86 b) is nearer to conspersa (86 a), costal-marginal half lighter whitish, with 
more indistinct markings, all the oblique streaks above the inner margin strongly dentate. Expanse of wings: 
22 mm. Khasis, Assam. 
N. ochracea sp. n. (86 b). Similar to penicillata Strd. (86 b) in the scheme of markings, but the ground* 
colour of the forewings is ochreous instead of white, sometimes a little darker greyish, transverse lines whitish, 
the exterior one never blackish on the basal side, which is the main difference from penicillata. No dark 
central dot. Hindwing greyish ochre, lighter than in penicillata, for which reason the white fringe is less 
conspicuous than in penicillata. Expanse of wings: 13—17 mm. Kwang-tung, in 2 generations, April till June 
and July till August, bred by Dr. Mell from larvae on peach. <3, $ types from Mahn-tsi-shan (Berlin State 
Museum). 
N. form os an a Mats, differs from nigrisigna in its velvety white forewing, the costal margin and two 
thirds of the underside being blackish. Fringe pure white with a few black scales. A blackish streak from the 
centre of the costal margin to the margin at vein 3. Hindwing grey, fringe white. Expanse of wings: 17 mm. 
Formosa, in May. 
N. nigrisigna Wil. Forewing white, densely dusted with brownish ochre, with a curved white ante- 
median and postmedian line, the latter line bordered on the inner side of the anterior part by a curved blackish 
line, black scales at the cell-end and black marginal dots. Hindwing whitish, dusted with brownish ochre. 
Expanse of wings: 15—22 mm. Formosa, South China (Kwang-tung). 
N. penicillata Strd. (86 b) entirely resembles nigrisigna, but separated by its smaller size, expanse of 
wings: 11—15 mm. Formosa. — I cannot decide whether penicillata and the following 5 forms are entitled 
to be regarded as species, because I had no sure species before me. 
N. kanshireana Mats, differs from nigrisigna in the following respects: forewing narrower, more rounded 
at the interior angle, costal margin and base (excepting a yellow spot) silky white. Below and beyond the 
cell yellowish-brown spots, at the base of 2 or 4 blackish scales, margin without dark dots, only with some 
dark scales. Hindwing pale yellow, apex without blackish scales. Expanse of wings: 21 mm. Kanshirei, For¬ 
mosa, in August. Recently placed by the author as a synonym to corusca.
