to the anal angle. Marginal spots as in semialba. — In dealbata Warr. only the distal margin is smoke-brown, 
the band on the hindwing pale. Expanse: 42—55 mm. New Guinea. 
C. albisecta Warr. Fore wing greyish-black, in the distal area undulate black streaks. Costal margin 
white with black dots. An oblique white band from 2 / 5 costal margin to 4 / 5 inner margin; hindwing with a 
black submarginal band, in front broad; 2 black marginal spots. 
C. atramentaria Warr. (72 c). Forewing blackish-brown. At the base a small white triangle the exterior- 
angle of which extends to behind the cross-vein and from there rectangularly curved to % inner margin. 
Hindwing white with a broad black band. Its inner margin from the centre of the costal margin to the inner 
margin. — extensa Rothsch. shows the white places in the forewing more extensive, the dark ones more grey 
and brown. Under surface more uniformly coloured. Dutch New Guinea. 
C. caudiferaria Bsd. (72 c). The dark costal margin of the forewing widens towards the apex, distal 
margin still broader blackish-brown. In the hindwing the marginal band is considerably far away from the 
white distal margin. — In pannata Fldr. the apex of the forewing is much broader dark by the rounding of the 
white ground-colour. Expanse: 45—50 mm. Batjan, Halmaheira, Waigeu. 
C. latimarginata Swh. (72 c). Costal band of forewing broader than in caudiferaria. Marginal band of 
hindwing still farther distally removed, often reaching the margin, so that the black anal spots vanish in it. 
Expanse: 50—55 mm. New Guinea. 
C. phantasmah Fldr. (72 c) is much larger than the two preceding species. Costal margin and distal 
margin in front and behind very narrow brown, often almost quite white. Expanse: 58—65 mm. New Guinea. 
3. Genus: Stroplilclia Him. 
Palpi long, delicate, porrect. Antennae thin, dentate. Hind tibiae with terminal spurs, in the $ with 
a long hair-pencil. On the forewing the costal margin is curved, the distal margin straight. Veins 3 and 4 
from the cell-angle, 6 + 7 and 8 + 9 stalked. In the hindwing veins 3 and 4 from the lower cell-angle, 6 and 7 
from the upper one. Type: fasciata Cr. 
St. fasciata Cr. (= caudata F.) (72 d). Forewing with a few black dots at the costal margin. Three 
double subbasal brown lines, behind them 2 median and 2 postmedian ones which are more or less forked 
towards the costal margin, 2 submarginal double lines. Marginal line black. Hindwing with fewer brown lines. 
Expanse: 50—65 mm. India, Sumatra, Borneo. 
St. directaria Wkr. (72 d). Less profusely covered with brown almost single lines, especially the 3 
subbasal ones not double. Expanse: 50—60 mm. Amboina, Ceram, Aru, New Guinea. 
4. Genus: Acropterls Hbn. 
Palpi delicate, long. Antennae of C thick, filiform. Neuration of forewing: veins 2 + 3 in the <$ on a 
short stalk rising near the base, in the $ separated, and 3 rising with 4 from the same place. Besides 6 + 7 and 
8 + 9+10 stalked. In the hindwing veins 3 and 4 rise from the lower angle, 6 and 7 from the upper angle. 
Sometimes vein 1 of forewing is strongly bent. Costal margin of forewing bent, apex mostly sharp, distal margin 
straight. Hindwing at the base of the costal margin with a projecting lobe. Distal margin tailed, angled or 
rounded. The white ground-colour of all the species is more or less intensely brown or greyish-brown. The 
typical species striataria shows quite an abnormal neuration, the cross-vein of the forewing showing a slanting 
position. 
A. ciniferaria Wkr. {== obliquaria Mr.) (72 e). Wings densely covered with fine brownish ochreous 
scales. Forewing with plain broad faded bands from % inner margin straight and from % inner margin slightly 
curved to the apex. Hindwing with a subbasal, a median, and an exterior slightly curved band. On the small 
tail a black spot, and mostly also before and behind it a few fine marginal dots. Beneath only at the costal 
margin of the forewing brownish, otherwise white. India, Java, Borneo, Dammer. — In vagata Mr. (72 e) 
the bands of the forewing are broken up into double lines, the bands of the hindwing are formed of striae, 
more distinctly contrasting with the ground-colour. The spot on the little tail is very small. From the same 
patriae. — In luteopicta Pouf., from Siam, the marking is quite indistinct. It probably belongs to this species. 
Expanse: 32—40 mm. 
A. inchoata (72 e) Wkr. Forewing rather pui-ely white with few black dots at the costal margin, 2 pale 
brown bands from % and % inner margin, nearing each other towards the apex. Marginal area sometimes finely 
striated brown. Hindwing with a subbasal, a median and a distal pale brown band being slightly curved. On 
the little tail a black spot. Before and behind it at the margin 1 or 2 fine dots. Mysol, Amboina, Batjan, New 
Guinea. — In simpliciata Rob. the ground-colour is of a purer white, at the apex of the forewing the bands are 
obsolete, on the hindwing only the median one is present. Goram. Expanse: 30—38 mm. 
A. reticulata Warr. Forewing dingy white, costal margin with fine brown striae. The whole wing with 
partly reticulate transverse striae. An indistinct double grey line from the inner margin behind the middle 
dealbata.
