- This median line is dark, faded, broad. basalis Hmps. (35 h) is similar to the 7th form, but besides with 
a black interior band from the costal margin to vein 1. 24—26 mm. Madras. 
N. lignea Wilem. Pale reddish ochreous, browner in the marginal area. Ring-macula and reniform 
macula paler, a brown spot between them. Submarginal line grey, indistinct, four blackish brown spots before 
it, a similar spot at the middle of the inner margin. Blackish marginal spots. Hindwing dark brown, lighter 
at the base. The costal margin at the base and the distal margin more intensely brown in the 2. 30 mm. A 
couple from Luzon. 
N. melanosticta Wilem. <b West. Like lignea also similar to lapidaria. Forewing greyish yellow with 
a brown tinge over it. A blackish brown spot below the base of the cell and two similar ones near the apex. 
Hindwing dark brown, somewhat diaphanous at the base. 26 mm. 1 ^ from Manila. 
N. perlignealis Wkr. (35 g). Body pale red-brown. The forewing light olive yellow. Triangularly faded 
red-brown at the inner margin, at the distal margin as far as vein 5 upward. A red-brown band from the middle 
of the lower edge of the cell to the inner margin. Tufts of white scales at the cross-vein. Submarginal line 
white, somewhat undulate, with dark brown spots at the costal margin. Hindwing brownish. 24 mm. Since 
1863 the 2$? from which the description was made seem to have remained the only specimens known. Borneo. 
N. rubripictalis Hmps. and the following species are somewhat less scantily marked. Forewing pale 
olive green, the median area below the cell and the marginal area dusted with red-brown. Interior line red- 
brown, double, undulate, indistinct, with dark scales at it in and below the cell. Median line red-brown, double, 
bent. The reniform macula edged with red-brown, with a black central spot. Exterior line as indistinct as 
the interior one, with three black spots in the anterior part. Submarginal line white, with dark dots outside. 
Hindwing pale red-brown. 1 20 mm, from the Louisiads. 
N. dialeuca Hmjjs. (35 h). Forewing pale reddish brown with a white band through the cell to the distal 
margin below the apex. Black striae at the costal margin. Median line double, the branches united at vein 1. 
Reniform macula edged by tufts of black scales. Exterior line double, finely notched, excurved behind the 
cell. Submarginal line fine, white, with dark spots at the apex and anal angle. Hindwing brown, diaphanous 
in the basal area. 1 $, 26 mm, from Borneo. 
N. perstrialis Hmps. Forewing brownish ochreous, red-brown below the cell and vein 5, a similar band 
from the upper cell-angle to the apex. Interior line indicated by two black dots. Reniform macula above edged 
with black dots, filled with brown and white below. Exterior line composed of black dots, obliquely inward 
from vein 6. Submarginal line likewise of black dots. Inner margin dark brown at the end. Hindwing pale 
red-brown, darker at the margin, the costal margin white. 28 mm. 1 $ from the Luisiads. 
N. purpurascens B.-Bak. (35 h). Forewing lilac black at the base below vein 4 and as far as the middle 
of the costal margin, the rest reddish brown. Interior line black, only discernible below the cell. A fine luna 
at the cross-vein, tufts of erect scales in the upper angle. Exterior line double, excurved in the middle and at 
vein 1, divided by a light streak extending from the lower cell-angle. Submarginal line traceable. Hindwing 
dark brown, somewhat diaphanous at the base. 28 mm. 1 $ from New Guinea. 
N. albicans Pagst. (31 c) resembles a better marked perlignealis (35 g). Forewing yellowish ochreous in 
the anterior half, bright red-brown above the inner margin, somewhat yellow only at the inner margin near 
the base. Interior line white, only discernible in the red-brown area, a blackish spot behind it at the lower edge 
of the cell. Reniform macula red-brown in light surroundings. Submarginal line whitish, undulate, with two 
black spots at the costal margin. Hindwing dark brown. $ 28 mm. New Britain. 
10. Genus : Sadarsa Mr. 
Separated from Nigramma by the extended tuft on the thorax in front and behind. The wings of the 
two species known are stretched, badly marked. Type: longipennis Mr. 
S. longipennis Mr. (35 g). Thorax and forewing brown, with a lilac gloss. Interior line double, dark, 
undulate, mostly indiscernible. The maculae indicated by a few tufts of erect scales. Median line excurved 
in the cell, exterior line double, undulate, very oblique, both as indiscernible as the double submarginal line. 
Hindwing reddish brown, somewhat diaphanous at the base. In the $ the apex of the forewing does not pro¬ 
ject so extremely. 36—40 mm. Sikkim, Assam. 
S. tenuis Mr. (35 g) is somewhat smaller and darker. The maculae also indicated by a few tufts of 
scales. Transverse lines strongly notched, very oblique. Hindwing as in longigiennis. 35—40 mm. Sikkim. 
11. Genus: Gyrtona Wkr. 
Except the first species differing much in the shape of its wings the others resemble the Nigramma- 
species by their narrow wings and insignificant marking. The second palpal joint is hairy above and below
