This insect comes very near to the P.teutonia of Godart and Donovan, particularly in its underside.

It is, however, smaller than that insect.

The upper wings are white, with a posterior broad black subtriangular border, having two or three white spots at the apex.

These wings have a black spot near their middle, which is also on the underside, but there communicates by a transverse, short, and rather curved, black band, with a black superior edging of the wing.

In other respects the underside of the superior wings is like the upper, except perhaps that it is yellowish at the base.
