surrounded by yellow and then finely by black. On Melastoma sanguinea. Pupa similar to that of alecto, but 
the proboscis-case is flatter with a sharper edge. Imagines in the evening on blossoms; they occur in fndo- 
China to the north as far as South China, to the south as far as Sumatra and Borneo. - Larva difficult to breed. 
Th. japonica Orza (Vol. II, pi. 42 b). This species having been minutely described in Vol. II inhabits, japonica. 
beside the palaearctic region, also China to the south of the Yangtsekiang R., and Formosa. Similar to firmata, 
paler; for further particulars vid. Vol. II, p. 259. — Larva also described there; on Cissus and species of Vitis, 
and on the Saxifragea Hydrangea paniculata. Imago not rare, swarming in the evening on blossoms of Mirabilis, 
on melon-blossoms etc. 
Th. lycetus Cr. (= japonica Piep. nec Orza, prunosa Btlr., rosina Btlr.) (68 d) differs from japonica lycetus. 
in the dark yellowish-brown coating which overshadows the light oblique stripes on the wings and body. From 
the Himalaya and North India to the south as far as Ceylon, Malacca, and Java. 
Th. oldenlandiae F. drancus Cr., argentata Haw., gortys Hbn., puellaris Btlr., proxima Aust.). The oldenlan- 
northern form, the typical one, has been figured in Vol. II, on pi. 42 b and described on p. 259. It is characterized 
by the broad white oblique stripe of the forewing, which is proximally bordered by a black oblique stripe being 
strongly thickened towards the inner margin. From North-West India through China to Japan, and to the 
south from Ceylon across the Sunda Is. and Malacca to New Guinea and the Key Is.; to the east as far as 
Formosa and the Philippines. ohvacens Mell are specimens from South China, exhibiting a more intensely olivacens. 
golden brown body, the dark oblique band in the costal portion of the forewing not being sharply defined 
proximally. - firmata Wkr. (68 c) from Australia, is strongly coated with brownish. - Larva deep dark brown, firmata. 
almost black, peculiarly dotted light, particularly in the sides. On the rings 4 and 5 there are lateral fictitious 
eyes, on the following rings only yellowish lateral spots. Horn very long and thin. On species of Vitis, Arum 
decurrens, Caladium, Colocasia, on Balsamineae and other plants. The caudal horn is very agile and may be 
raised and lowered (Semper). Pupa brown, marked with black; it has no projecting proboscis-case, but a 
coniform snout. Imagines common in most of the districts of their range, though more in the plains. 
Th. pinastrina Mart. (= silhetensis Wkr., bisecta Mr.). The species occurs in 2 forms which, however, pinastrina. 
cannot be strictly separated. In the typical form the space between the 4th and 5th lines on the forewing above 
is broad, and line 5 thicker than 6; from North India to Ceylon and across Indo-China and Malacca, Java, 
Sumatra, Borneo to China, Formosa, the Lu-Chu Is. and Japan, where the species passes over to the palaearctic 
region (cf. Vol. II, p. 259 silchetensis). In the second form, intersecta Btlr. (68 c) the space between lines 4 interseda. 
and 5 is narrower than in pinastrina , and line 6 is not thicker; this form occurs in the Papuan region and extends 
from Australia (Queensland) across New Guinea and the Bismarck Archipelago and Sumba to Amboina, 
Celebes, and the Philippines. — Larva green or earth-coloured with lighter lateral stripes, on the 4th to 10th 
rings dark-centred eyes surrounded by dark; horn small. It chiefly lives on Taro (Colocasia antiquorum), also 
on Jussieua. Imagines common nearly everywhere, where Taro is grown. 
Th. margarita Ky. (= marginata Swh., phoenix Misk.) (68 c) is mostly smaller than typical pinastrina margarita. 
which it entirely resembles otherwise; also similar to oldenlandiae, but the white, dark-edged oblique stripe of 
the forewing is duller and narrower; the median stripe across the abdominal dorsum is not so bright silvery 
white. Australia; distributed in Queensland, though not very common. 
Th. brunnea Smpr. (= buruensis Bothsch.) (68 d). Body as in the preceding species dark brown with brunnea. 
a white median line. Wings also dark brown; forewing so very much darkened that there are only traces 
noticeable of the oblique stripe through the wing. Separated from the following species particularly by the 
absence of the white median streak on the tegulae. New Guinea, Buru, Philippines; type from South-East 
Mindanao. 
Th. turneri Luc. (= mira Swh.) (68 c) is smaller; forewing similarly coloured and marked as brunnea', turned. 
recognizable by the brighter white marking of the body showing on the tegulae a white median stripe, on the 
abdominal dorsum small white spots on the 3rd to 5th rings. Queensland. 
Th. insignis Btlr. (= jordani Huwe) is at once recognizable by the undulate silvery white line extending insignis. 
from the apex through the whole forewing to the centre of the inner margin and from there to the base of 
the wing. The typical form comes from the Andamans and differs from the figured kuehni Rothsch. (= insignis kuehni. 
Sn. nec Btlr.) (68 c) not only in its larger size but also in the forewing being more pointed and the light stripe 
on the forewing less curved. Java, Dammer, Larat, Tenimber. 
Th. griseomarginata Hmps. is evidently a very rare lepidopteron from Sikkim; only very few specimens griseo- 
are known. Antennae long, extending beyond the end of the cell of the fore wing. The white dorsal line on the marginata. 
abdomen is plain. On the forewing a whitish submarginal band extends from the apex almost to the anal angle. 
Th. pallicosta Wkr. (= callicosta Men.) (68 b) is a very elegant lepidopteron; the costal and posterior pallicosta. 
margins of the beautifully purple brown forewing are bordered with bone-white, at the cell-end there is a white 
central dot. The thorax also shows lateral white borders and a purely white median line. — Larva brown or
