apex. The black thoracal spots are smaller than in typical plana, particularly those of the patagia. In the $ 
the basal spots in the cell are not united and the thoracal spots still smaller; the hindwing has no postmedian 
fergussonis. spot, but only a very small one at the cell-end. — fergussonis Bothsch., from the Islands of Fergusson and 
d’Entrecasteaux, is entirely like the preceding form, but the submedian fold of the forewing only very faintly 
shaded with brown or entirely white. The basal spots separated, the hindwing above and beneath with 2 
indistinct, small postmedian spots on vein 6 and below vein 2, the thoracal spots scarcely larger than in albifera 
donatana. but the middle streak on the mesothorax strong. -— donatana Swinh. from Tenasserim is probably also allied 
to this group, particularly to persecta, but on the forewing the 2 black punctiform spots are absent at the inner 
border of the costal band, and the apical white spot disappears in the white of the disc; on the hindwing the 
band is narrower and is parted by the ends of the veins, the three discal dots of persecta being absent here. 
albiformis. A. albiformis Swinh. (28 g) from Borneo and the Philippines. The white spot behind the upper cell- 
angle broadly flows together with the discal area, the white hindwing in the disc unspotted, but with a rather 
ternatensis. broad, dark distal band. — ternatensis Bothsch. from Ternate exhibits a less pointed, lower, distal angle of 
the white area of the forewing, being more rounded off; the black colouring extends at the costal margin to 
the base, so that scarcely a trace of the small, black basal spot is noticeable there. 
clara. A. clara Btlr. (28 h). The only specimen before me shows very extensive, white areas, the hindwing 
without a dark margin, the brown of the forewing paler, the thorax white, the abdomen light ochreous-yellow. 
Java. Apparently rare and flying only at considerable altitudes; captured by Frtjhstorfer on Mount Gede 
at an altitude of 4000 ft. 
suffusa. A. suffusa Snell. (28 li). Forewing preponderantly shaded with dark, the white reduced to a small 
area behind and above the upper cell-angle, behind the cell and above the proximal margin. The hindwing 
with a broad, brown marginal band strongly narrowed towards the proximal angle. Flores, Alor. The animal 
is known to me only from the figure (in the Novitates Zoologicae) which I copy. 
isthmia. A. isthmia 1 Ykr. The forewing is likewise very extensively dark brown, the white spotting reduced, 
in specimens from Negros less so than in S<S from Mindoro; beneath the white band behind the cell is broader. 
The hindwing with a dark marginal band, otherwise unspotted. Philippines. 
tortuosa. A. tortuosa Moore (28 h). Forewing rather irregularly spotted, the white area oblique and at both 
its margins strongly dentate and sinuous. The hindwing with an irregular, dark marginal band divided into 
spots by the veins and several dark discal spots; the base of the forewing like the body of a light ochreous 
yellow, brightly spotted black. North India to China, where it proceeds in the Omei-shan to the palearctic region. 
The species undoubtedly shows a mimetic resemblance to certain Geometrids of the A&raras-group, such as 
Metabraxas rufonotaria (Vol. 4, t. 14 d), Percnia luridaria (Vol. 4, t. 14 e), and P. girafjata (Yol. 4, t. 14 f) all 
of which also fly in the Omei-shan. 
contorta. A. contorta Aur. entirely resembles tortuosa by the colouring of the hindwing and abdomen, but it 
differs otherwise very much. The posterior margin of the forewing is longer than in other Asota and the distal 
margin is short; by this shape of the wings the species is quite isolated in the genus and approximates only 
kinabaluensis. From Sukabumi, at an altitude of 2000 ft., taken by Frtjhstorfer in Java. 
kinabaluen- A. kinabaluensis Bothsch. (28 h), from the Kina-balu in North Borneo, is in the distal half of the forewing 
SiS - blackish-brown, in the proximal half white, spotted brown. Between the radials a square, white spot. Hindwing 
white with an irregular dark margin and blackish discal spots; the body is orange; thorax spotted dark, abdomen 
banded dark. 
8. Genus: Digama Moore. 
In this genus in which now also Indian Sommeria and sometimes the African Homaeognatha resembling 
the Asota or certain Spilosoma are included, there are about 15 forms mostly confined to India and Ceylon, 
one species, however, being also distributed over Celebes to Australia. Also here the 3rd palpal joint is very 
long, the forewing being of the shape of some Lithosia, often also with a marking resembling Chionaema. The 
subcostal veins anastomose on the forewing, forming an areola, the lower radial comes from the lower cell-angle, 
the lower median vein rises before the last third of the cell. On the hindwing the last subcostal vein is petioled 
with the 1st radial; the uppermost median vein comes from the lower angle of the very short cell. The larvae 
are not known to me, the imagines seem to occur less frequently than most of the Msofa-species. 
hearseyana. D. hearseyana Moore (26 c). This species distributed through the whole of India to Ceylon has the 
forewing clouded light and dark, the basal part decorated with numerous, small black spots and the distal part 
with an irregular, dark marginal and submarginal band. Hinclwing yolk-colourecl, beneath with a black spot 
similis. at the cell-end. — similis Moore, described from Simla, in the $ exhibits a dark brown marginal stripe near 
the anal angle of the hindwing, and in both sexes another dark spot before the apex of the hindwing. The latter 
form is smaller, too. 
insulana. D. insulana Fldr. (26 c) differs from hearseyana by the unspotted collar and the absence of the dark 
bands of the forewings; it also occurs in Ceylon, and in South India. 
burmana. D. bumiana Hmps. is the size of the form similis-, the head, thorax and abdomen are marked as in 
the latter form, but the basal part of the forewing, beside the black punctiform spots, exhibits internerval streaks
