[2] | E. pyrrhus, the most multiform species of the genus, being the most widely distributed in the Malayan Archipelago and forming the most characteristic example of insular differentiability.

The two extremes of the colouring on the upper surface are exhibited by our figures 134 d (sempronius) with preponderantly yellowish green colours and uncovered basal region of the upper surface, and (jupiter [ now full species]) (135 a) with predominantly black bordering and the basal zone covered with black.

Female always larger than the male of a most variable development of the orange terminal margin of the under surface of the hind¬ wings.

Males sometimes on blossoming trees where they rest for some moments opening and closing their wings with a scratching sound similar to that of Prepona.

The larva feeds on species in the genera Acacia, Albizia, Robinia, Cassia, Celtis and Ponsiana.
