Altha adala Moore; Hering, 1931: 680.
Diagnosis. The forewings are more extensively shaded with dull orange than in the
other two species, somewhat squarer, and with a dark brown dot centrally. The
male genitalia lack an asymmetric juxta and have the distal half of the aedeagus
Taxonomic notes. A Balinese specimen is illustrated as the two Bornean males are worn;
they are somewhat larger.
Geographical range. Burma, Thailand, Java, Bali, Borneo; probably also in

greenish white, ovate, without tubercles. The host-plant in Java is Annona (Annonaceae);
