vein 7, then outcurved, with dark spot before the middle; then oblique. Before the margin a row of faint spots. 
Hindwings white, termen shaded with brownish distally towards inner angle. Fak-Fak, Dutch New Guinea. 
N. scabralis Wkr. (= parallacta Meyr., cerraunias Trnr.) (131), of very small size, outwardly resembling 
a Crambid, particularly in the long palpi. Forewings yellowish-grey with several darker costal spotlets and 
irregularly dentate oblique streaks before and beyond the middle and before the outer margin. Hindwings 
dull whitish-yellow, greyer at base. New South Wales, near Katoomba in the Blue Mountains, on Paramatta 
and Mount Kosciusko. 
N. porrigens Wkr. (= arachneis Meyr. (13 h), likewise from near Sydney, resembling the preceding 
form, but larger and more common; forewings grey, suffused with brown, with transverse bands more delicately 
dentate, and oblique costal bars extending farther towards the middle of wing. Hindwings tinged darker brown. 
N. paroxynta Meyr. (13a) likewise resembles the hitherto described forms together with which it is 
found; but forewings still darker grey-fuscous, and the oblique stripes either very finely serrate or smooth. 
On the submedian a heavy basal stripe lined with white above. South-Eastern Australia. 
N. nigrisparsa Hmps. (13 f) is similarly marked as the preceding forms, but the ground-colour of the 
forewings is clearer, rather white, with the dark transverse markings more distinct. Forewings with sharply 
defined discal spot, preceded by a dentate transverse streak and followed by two similar ones, curved, strongly 
convex toward the margin beyond the apex of cell. Hindwings dark fuscous-grey. Bhotan. 
N. argentalis Moore (1 3 h) may be easily recognized, aside from its considerable size (36 mm), by the 
silvery lustre of the forewings which are otherwise suffused with brown. At the base of the costa a large 
blackish spot, the transverse lines unclear, irregularly feebly dentate; fringes alternating black and white. 
Larva feeds on Castanopsis indica; dark yellow, with short yellow hair and indistinct dark dorsal line. Behind 
the head a tuft of black hair, supporting the shells of the old heads cast off in previous moults. Sikkim. 
2. Genus: Roeselia. 
The representatives of this genus are mostly of somewhat more robust build than the true Xola; 
frons not quite so broad, but often adorned with a crest of hair; tongue variable; antennae of c? mostly 
pectinate, tapering towards the end. At base of antennae a tuft of hair. On forewing vein 3 arises before, 
4 and 5 at angle of cell, 6 below the upper angle; 7, 8, 9 and 10 nearly always stalked. On hindwing vein 3 
originates at angle of cell, 4 is absent or united with 3, 6 and 7 stalked, 8 arising at middle of cell. The 
patches of raised scales on forewing similar to those of Nola, palpi frequently greatly lengthened, tibiae with 
strong spines. About 50 species are known in all tropical countries excepting the Continent of Africa, 20 of 
which are found in the Indo-Australian Region. 
R. argentescens Hmps. (13 f). Forewing dirty silvery grey, marginal area yellow, with fine, irregular, 
dark transverse lines; from the middle of the costa a large dark brown bar, crossing the apex of the cell to 
the middle of the wing, before which a small costal spot. Hindwings grey-fuscous. From Sikkim; one of 
the larger species. 
R. argyria Hmps. (13f), another large form, resembling the preceding. The large spot in the middle of 
the costa is greatly enlarged so as to be united with the second smaller spot distinguishing argentescens. On 
forewing the markings of the outer marginal half darker and richer; hindwings brown-grey. From Sikkim 
and the Khasia Hills. 
R. triangulalis Leech (Vol. 2, pi. 10 d), described in Vol. 2, p. 46, differs from the 2 preceding forms 
principally in having the ground-colour brown-grey instead of silvery-white, with the dark spot in the middle 
of costa indistinct. Sikkim; also Japan. 
N. nitida Hmps. (Vol. 2, pi. 10d) has the forewings silvery white, the large triangular spot in the 
middle of costa only faintly outlined, inside silvery-grey like the ground-colour. Before this spot a narrow, 
2—3 nnn wide, pale brown, dark margined transverse band. Widely distributed throughout the Himalayas: 
Dahlhousie, Manipur; enters in Cashmere the Palaearctic Region. Larva on Ilex; cf. Vol. 2, p. 48.
