Diagnosis. The species has a striking green rectangle in the anterior half
of the forewing, running from one quarter along the costa to three
quarters. The distal posterior angle of this rectangle is edged with white
and the basal one is linked to the dorsum by a green band. The base of the
forewing dorsum has a conspicuous white patch.
Geographical range. N.E. Himalayas to Borneo, Sumatra, and Sulawesi.
Habitat preference. The species is rare, taken only in the lowlands.
Biology. The larva was described by Bell & Scott (1937). It is rich
olive green, the thoracic segments and dorsum of the abdomen suffused
pale brown, with a broken, narrow dorsal stripe of dark brown. There is a
narrow dark brown dorsolateral stripe on the thorax, and a pale yellowish
brown lateral stripe that edges the ocellus below and is wavy over the
abdominal segments, associated with two broad inverted 'V' markings
centrally on the flanks. There are large dorsolateral ocelli on A1, their
surface enamel-like, centred with a black pupil and edged with dark, then
pale brown; the area between the ocelli is spotted with white. The horn is
olive green with a yellow tip.
Recorded host-plants (Bell & Scott, 1937; Pholboon, 1965) are: Lasia, Pothos (Araceae).
