Underside: forewing black all except the costal margin increasingly, the apex widely and the outer margin decreasingly, which are yellowish-ochreous; the semi-transparent spots as above, with two additional somewhat diffused opaque spots placed one above the other near the. middle of the submedian interspace, which appear in a somewhat constricted form on the upperside of one specimen. Hindwing yellowish-ochreous throughout; a black spot at the end of the cell and about six between the veins outside the cell; some obscure submarginal blackish spots; the abdominal margin and a streak in the submedian interspace black.

The markings of this species remind one at once of those of Plastingia noemi mihi; but there is only one spot in the cell of the forewing, and the yellow in the hindwing is larger in the species now described. Described from somewhat worn specimens collected by Father D. Honore, S. J., in the Pulni Hills of S. India.
