Hindwing light yellow with a large, dark spot towards the anal angle. $: forewing pale pinkish-brown with 
antemedian, median and subapical costal-marginal spots, a V-shaped or rounded spot on the posterior margin 
and one or two small spots at the anal angle. Expanse of wings: 50 mm, $ 76 mm. India: Bhutan, Sikkim, 
(Darjeeling); Formosa. 
N. siletti Wkr. (= quadriplagiata Wkr.) (41 g). <+ body dark brown, abdomen with white-fringed siletii. 
segments. Wings dark brown, forewing with a light orange band from beyond the middle of the cell almost 
to the margin. — $: head and thorax black. Abdomen orange with paired, ventral and dorsal brown spots. 
Forewing yellowish-white, a broad, black band of the posterior margin, from which an antemedian and a post¬ 
median, chocolate-coloured, oblique band extend to the costal margin, the postmedian band enclosing sometimes 
one (fa. inciusa form, nov.) or several (fa. biirtclusa form, nov.) white spots. Fringes likewise chocolate. Hindwing inclusa. 
light orange with a brownish-black subapical spot (which is sometimes absent = fa. silettoides form, nov.) and 
a similar one near the anal angle. Expanse of wings: $ 50 mm, $ 53 mm. India: Silhct, Sikkim, Cachar, Burma. 
- — illsignis Moore from Java seems to differ from siletti in the $ forewing by the yellow transverse band being insignia. 
ochreous at the costal margin, whereas in siletti this band is white. The $ is slightly larger than siletti (expanse 
of wings: 60 resp. 53 mm), and the proximal transverse band is straight and broader than in siletti, where it 
is slightly bent convex towards the margin. — delta form. nov. (41 g). $ from Kina-Balu (Borneo) has a larger delta. 
(4 x 10 mm) black spot at the anal angle of the hindwing, the distal transverse band of the forewing in its 
anterior half forms a delta-shaped figure and in its posterior half it is likewise expanded triangularly, but 
it encloses there an L-shaped light figure. (Berlin Museum). - — laeta Wkr. (41 g). The differs from siletti above laeta. 
by the broader, more extended and more yellow light bands and beneath by the basal half of the forewing being 
yellow at the costal margin like the apex of the wing. The $ deviates from siletti by the forewing being rounded 
off at the end and by the fringes showing yellowish-white tips. On the hindwing there is only a black spot situate 
quite at the distal margin and enclosing also the fringes. Length of wings: $ 22, $ 26 mm. Flying in February 
and October. Java, Philippines. 
21. Genus: Vhiacfclas Wkr. 
Forewing extended with a rather sharp apex and oblique border; the veins 3, 4 and 5 at the base very 
close together, but still remaining separate, 6 from the anterior angle, 7 and the footstalk of 8 + 9 from the 
apex of the areola. In the hindwing 3 and 4 are usually on a footstalk, and 6 and 7 mostly separate. 
Legs bare with short spurs. Quite a number of forms of this genus have been described, which, however, are 
nearly all confined to India and probably only form 2 species one of which is reported to be distributed over 
Arabia to Abyssinia. 
Th. vilis Wkr. (= indeterminata Wkr.) (39 f). Body and forewing grey, strewn with brown scales, vilis. 
Forewing with an indistinct, dark discocellular spot and a series of dark marginal spots. Hindwing white. 
Expanse of wings: 26, $ 32 mm. Southern India (Nilgiris), Ceylon. Is said to occur also in Arabia, Somali 
Land and Abyssinia. 
Th. postica Wkr. (= denatata Wkr., nigroscripta Wkr., curvata Wkr., basifusca Wkr.) (39 e). Body postica. 
and forewing greyish-brown, the latter with obliquely curved, subbasal and antemedian black double lines, 
which are angled behind the median vein, and with a double post median line being curved round the cell-end 
and bent proximally behind the cell and sending some streaks to the margin. Hindwing with an indistinct, 
curved postmedian line and a brown diffuse patch enclosing a dark streak, in the anal angle. Besides some 
marginal streaks. Expanse of wings: $ 38, $ 44 mm. India, Burma. — Larva with a red head marked with a 
white V-figure; body pale yellowish-green with a broad, white dorsal band margined by black, dentate lines, 
a lateral row of black spots and with 6 red tubercles exhibiting long, grey hair on each segment. Food-plant; 
Zizyphus jujuba. 
22. Genus: l>en<lro]>lilel>s limps: 
The only species belonging hereto is an animal of not very strong structure and with large wings, distinguish¬ 
ed especially by vein 1 a of the hindwing being connected with the proximal margin by 3 or 4 transverse 
veins. Otherwise in the hindwing veins 4+5 and 6+7 rise on a footstalk, whereas 3 rises almost from the 
angle; the hindwing projects considerably beyond the abdomen. In the forewing 4 and 5 are forked, 
6 and the long footstalk of 7 and 8 and 9 rise from the angle (8 and 9 being very short), 10 from the costal 
margin near the angle and seems mostly not to form an areola. Palpi very small and porrect. Posterior 
tibiae with two spurs. Antennae with long combs.
