Diagnosis.
The uniform dark brownish green coloration of the forewing, crossed by faint bluish fasciae, and the broad banding to the hindwing costa distinguish this species from other Bornean taxa. The forewing stigmata are often ringed slightly with bluish grey or are totally cream or white.

Taxanomic note. White-spotted specimens from Sarawak match a colour slide of the holotype (Kalimantan) exactly. Plain forms match a colour slide of the holotype of mixtus, described from Sumatra. The genitalia differences between the two forms noted by Holloway (1976) were found, on examination of more extensive material, to be variable and insignificant, hence the names listed above are brought into synonymy.

Geographical distribution. Borneo, Sumatra.

Habitat preference. The species is common, particularly in upper montane forest, on G. Kinabalu, G. Mulu, G. Api, Bukit Retak and Bukit Pagon, on Kinabalu it was recorded from as high as 2600 m. The white-spotted form was found to be very much rarer in all these localities except G. Api, where it predominated.
