T. pilaria Guen. (13 a). Also very near depulsata (11 k). Generally no terminal dots except a very small one 
at tail of hindwing, and even this occasionally wanting; lines generally approximated; fringes green proximally, 
whitish distally. Discoloured specimens can still be distinguished from chloropis by the less long palpus and 
in the by the rather shorter hindtibial process, that of chloropis reaching to near the middle of the 1st tarsal 
joint; also by having the 2nd radial of the forewing rather less extreme and the 1st median just stalked. Society 
Islands (type), Samoa and Fiji. In the last-named locality, Veitch and Greenwood have found the larvae 
on Rosa, Ricinus, Inocarpus edulis, Mangifera indica, and Eugonia indularis. 
T. halioscia Warr. may be a race of pilaria, though with some superficial appearance of curiosa. Ab¬ 
domen with white dorsal dots. Solomons. 
T. minor Warr., from British and Dutch New Guinea, differs from dorsipunctata in that the 3rd joint 
of the $ palpus is longer, the discocellular of the hindwing not white. It might possibly be a form of byrsopis, 
but I separate it by its white dorsal spots and more crenulate outer line. $ palpus shorter than in halioscia. 
T. zothalmia sp. n. (11 k). 38—43 mm. Near minor and dorsipunctata in the red face and white ab¬ 
dominal dots, hindtibial process of the $ rather longer; terminal joint of $ palpus about as long as 2nd. More 
vivid and more opaque green than in the allies, the white strigulation very slender, the markings quite weak, 
but the black terminal dots nearly as strong as in dorsipunctata. Further characterized by an accession of 
bright yellow colouring on the legs and a part of the breast. New Ireland, 5 and 4 including the type 
cj; New Britain, 2 GS and 3 $$; all in Mus. Tring, collected by A. J. Eichhorn. 
T. dorsipunctata Warr. A large species, similar to byrsopis. Forewing with a white dot or small spot 
on 3rd discocellar at its most proximal part; hindwing with more slender white dashes on 2nd and 3rd disco- 
cellular. Described from Aroa River, British New Guinea, but distributed in New Guinea and Vulcan Island. 
Rook Island and New Britain produce a race or very close ally of which more material is awaited. 
T. tanymelea Prout is extremely similar to dorsipunctata but differs in structure. Palpus in both sexes 
longer, 3rd joint in $ almost, in $ fully, as long as 2nd. Antennal pectinations of $ longer. Hindtibial process 
of $ longer. Forewing with the outer line weakened, by the suppression of white vein-clashes. Rook Island; 
subsequently received from N. E. New Guinea and New Hanover. 
C. Markings not typical. 
T. curiosa Sivinh. (11 k). Face green. Hindtibia not dilated. Distinguished from the preceding groups 
by having darker green discocellular and shading proximally to the outer white line, which line, however, 
is nearly obsolete, only suggested by some indistinct, crenulate pale marking. Assam, Penang, Selangor and 
Celebes. — umbrimedia Warr., from New Guinea and the Bismarck Archipelago, seems to be a smaller race, 
if not almost a synonym. 
T. pantascia West (Ilk). Extremely similar to curiosa, perhaps a race; postmedian line of forewing 
rather straight, of hindwing rather less strongly produced centrally than in the allied forms. Luzon. 
T. aptifimbria Prout. Face and hindtibia as in curiosa. Lines punctiform, as in the two following, 
the postmedian white spot on hindmargin of forewing conspicuous, but less large than in them. Fringes green, 
at least in proximal half. Sikkim and the Khasi and Kachin Hills. 
T. hypocrites Prout (11 k). Hindleg of $ simple, as in aptifimbria. Otherwise scarcely distinguishable 
from leucospilota. The type was from Singapore, but the species is distributed in India and known to me also 
from Penang and Sumatra. — vivida Prout is a brighter green race, with rather broader hindwing. Central 
Ceram: Manusela. 
T. leucospilota Moore is characterized by having the upperside of the <$ hindtibia fringed throughout 
with very long, light hair. Ceylon and Travancore. 
T. leucoceraea Prout (13 a). Rather near the three preceding species in size and habitus. The puncti¬ 
form white lines obsolete. Hindwing with a conspicuous white spot on the 2nd discocellular. Fringes not so 
sharply spotted as in hypocrites. Hindleg simple. Malay Peninsula: Kedah Peak. 
T. floccosa Prout. Upperside much as in leucoceraea, but with postmedian white dots on the veins. 
Hindwing of J beneath, from base to beyond middle, clothed with bright red-brown hair. Similarly coloured, 
long hair on hindleg and on base of abdomen beneath. Wellesley Province, Malay Peninsula. Several examples 
subsequently received from Mt. Gedeh, Java. 
T. charops Prout. 53—54 mm. Face green. Abdomen with a whitish longitudinal line. Wings bright 
green, with the postmedian line normal (rather proximal), but with a very characteristic white, red-ringed 
cell-spot on hindwing. Samoa.
