Abstract
Since Corbet (1941) showed the classification of Euthalia agnis (Snellen van Vollenhoven, 1862) (type locality: Java) and its related taxa, agnis and tinna Fruhstorfer, 1906 have been treated as a single species. Because the characteristics of the specimens from the Malay peninsula and Sumatra which we recently obtained are different from those of the Javanese specimens, the agnis complex should be treated as two species, E. agnis and E. tinna, as shown by Fruhstorfer (1906, 1913).
