Diagnosis. The several postmedial lines of the forewing are more even in
intensity, extending to become constricted together before disappearing
just subcostally; in dohertyi they continue to the costa, and in malayana
they are only really strong at the dorsum. There is never an obvious
longitudinal dark shade to the marginal angle. The pale submarginal band
of the hindwing is more uniform than in dohertyi and malayana.
Geographical range. N.E. Himalaya to Sundaland.
Habitat preference. This is probably a lowland species. No specimens have
been taken in recent surveys.
Biology. Dupont & Roepke (1941) described and illustrated the larva.
The young larva is green with a pinkish horn. The pairs of ocelli develop
as black dots in the third instar. Later instars are green, dark grey, or
even bluish. The green larva has brown-ringed black ocellar spots, with
two rows of four white spots between them. The darker ones have ocellar
spots, but also pairs of dark dorsal spots on the abdominal segments, and
some weak longitudinal banding.
The host-plant recorded was Lasia (Araceae).
