Diagnosis

The male is almost entirely dark brown, the forewings apically produced and with a broken subbasal green band; the hindwings are relatively small. The female resembles a specimen of the previous species but the green band of the forewing is narrow, especially the dorsal two thirds, and the dark subbasal patch extends right across the wing rather than just over the costal half.

Geographical Range

Java, Borneo, Peninsular Malaysia, Sumatra.

Habitat Preference

Bornean specimens have been taken only in Sarawak, in the lowlands around Kuching.

Biology

The larva was described and illustrated by Piepers & Snellen (1900). It is dark green with four broad longitudinal, elevated dorsolateral and lateral ridges on each side, and slightly lighter green transverse ones on each segment, yielding a network of elevated ridges. The longitudinal ridges bear spined tubercles at the intersections with the transverse bands; the dorsolateral row is complete with no tubercles larger at the extremities, though there are black spots at each end of the larva. The cocoon is oviform-flattened, yellowish brown, enveloped in thick yellow silk. The host-plants recorded are Mangifera (Anacardiaceae) and Nephelium (Sapindaceae).
