Forewing above at most with two blue submarginal spots in cellules 7 and 8; rarely in the female with several yellow ones; the blue (male) or greenish (female) median band is 2-7 mm broad at the hindmargin of the forewing and 4—12 mm in the middle of the hindwing, and is only a little widened posteriorly; the spot in cellule 2 of the hindwing does not completely cover the base of the cellule and the narrow spot in cellule lc does not reach the cell; forewing beneath almost always entirely without submarginal spots. [Nominate] Median band of the forewing above well developed, the spots of cellules 2—4 obliquely cut off distally; the discal spot in cellule 2 of the hindwing is very long and produced farther towards the anal angle than the spot in cellule 1 c.
