636 CHADISRINA; PARACHADISRA; PSEGMAPHORA. By M. Gaede. 
I. Antennae of tufted. 
Ch. bipars Wkr. (= basalis Mr.) (84 f). Red-brown, at the base with fine pale streaks, distal area often 
somewhat greenish. The dark median band similar to the following species, beginning vertically to the costal 
margin. Two undulating exterior lines with a brown spot between them at the costal margin and inner margin, 
and a submarginal row of black dots. Hindwing pale greyish-brown with a dark marginal line and anal spot. 
In the $ the base of the forewing is whitish ochreous. 36—50 mm. Ceylon. In the specimens from New Guinea 
the anal spot is still more connected with the main spot. — The larva is above greenish white, beneath green, 
with pale green oblique lateral lines. Dorsal line yellow, edged with grey, on the 11th segment a red pro¬ 
tuberance. - albobrunnea Rothsch. shows the distal area hued with a greenish brown, only the spot at the costal 
mragin being distinct. Khasia Hills, I. of Obi, New Guinea. — semiferrea limps, is presumably also only a 
form of bipars. The two exterior lines and the spot at the inner margin are absent, so that the median line 
distinctly runs to the inner margin. Ceylon, Manila. A from Choiseul also lacks the greater part of the 
anterior spot. 
Ch. basivacua Wkr. (= calapana Smpr., bipartita Mats.) (84 f). Similar to the $ of bipars. Thorax 
and base of forewing light yellowish wood-colour, as far as the rusty brown or dark brown median line, at vein 2 
also beyond the latter light. Exterior lines mostly rather indistinct. The spot belonging to the latter at the 
costal and inner margins may be almost absent. 36—46 mm. Sunda Is., New' Guinea. In a $ from New' 
Pomerania and a B from Buru the fore wing is almost uniformly dark brown, the marking nevertheless very 
distinct. The specific difference of bipars and basivacua is somewhat questionable considering the variability. 
— For bipartita Matsumura established the genus Stenoshachia. 
Ch. striata Rothsch. The median line is almost similarly arranged as in bipars. Exterior spot only 
indicated at the costal margin. Ground-colour greyish-yellow wdth 2 broad dark radial bands below' the costal 
margin and to the centre of the distal margin. - divisa Rothsch. (84 e) shows the basal area as far as the median 
line of a purer brown, otherwise not different. 45—55 mm. New Guinea, New Pomerania. 
II. Palpi shorter. Antennae of A pectinated, at the t i p s plain. 
Ch. atrifusa Hmps. Thorax greyish-brown, abdomen reddish-brown. Forewing suffused with brown 
and black, grey spots at the base, at the centre of the costal and inner margins and in the distal area. Interior 
and exterior lines double, undulating. At the cross-vein a luna. Hindwing yellowish-w'hite, at the margin 
darker, q 50 mm. Khasia Hills. 
Ch. meeki Rothsch. (84 g). Basal area dark brown, below the cell only moderately bent foreward. 
Median area more or less hued with green. The interior border at the costal margin vertical to the inner margin, 
thus more slanting than in the first group, outside bordered by a sharply notched white line. Before the latter 
another obsolete parallel line. Behind it and before the submarginal line dark spots. Hindwing yellowish, at 
the margin red-brown. $ on the forewing in the median and marginal areas more brownish-green, the marking 
more faded. 45—58 mm. New Guinea (Mt. Goliath and Nomnagihe, as high as 2000 m). 
65. Genus: ( hadisidiiii gen. nov. 
Palpi short. Antennae of $ pectinated as far as % of their length. Forewing somewhat broader than in 
Chadisra, similarly marked. Veins 6 —(- 10 -+- 7 -f- 8 -H 9 stalked, the basal stalk very long. Hindwing broader 
than in Chadisra. 
Ch. variegata Mr. Forewing pale violettish-brown; at the base, around the median line, near the apex 
and at the anal angle rusty yellow. Hindwing reddish-brown with a light exterior line and a rusty yellow anal 
spot. B 52 mm. Sikkim. 
66. Genus: Paradiatlisra gen. nov. 
Palpi of B and $ short. Antennae of <$ tufted, of $ plain. Forewing similarly shaped and marked as 
in Chadisra. Vein 6 near the apex of the accessory cell, 10 + 7-1-8 + 9 from its apex. Hindwing narrower 
than in Chadisra. 
P. varians B.-Bak. (84 e). Forewing brownish-grey with a large slate-coloured spot from the cell-end 
to the distal margin. Median line as much excurved as in Chadisra, inside broadly edged with darker brown. 
Exterior line in front notched, above the inner margin with 2 or 3 dark spots. At the costal margin before the 
apex lighter brown. In the $ the whole marking is darker, more faded. Hindwing of $ white, in the $ broadly 
margined with brown. 50—58 mm. New Guinea (Mt. Ivebea, Nomnagihe, as high as 2000 m). 
67. Genus: Psegmapliora gen. nov. 
Palpi upcurved to the upper edge of the eyes. Antennae of B pectinated to % of their length. Patagia 
bent up fan-like. In the forewing veins 3 and 4 distantly separated, 6 from the upper cell-angle, 10 and 8 + 9 
from the apex of the accessory cell, 7 close next to it.
