Male: Forewing very variable in shape, especially in the outline of the termen and dorsum. In the type it is comparatively long in proportion to width owing to the less convexity of the dorsal margin, and has the termen oblique, slightly convex; in var. novarae it is remarkably broad, the great convexity of the dorsal margin making it almost subquadrate, while the termen is more convex than in the typical form. In the female the difference is less marked. Typical form. Upperside: forewing dark brown suffused up to the termen with a brilliant blue gloss; a spot in apex of cell, a small costal spot, two short streaks beyond apex of cell, and in the female two discal spots: in the six subterminal and terminal series of spots; in the female the latter series wanting: in both sexes the subterminal spots produced inwards. All the spots bluish white.
