Description from Seitz
P. sesostris. Forewing in the male with very large green area which touches the cell; hindwing either black or with a red spot before the hindmargin. Forewing of the female with at least two white spots; the red band on the hindwing generally broad. Scent-organ of the male with white wool, except at the base, which is black. Mexico to the Amazon, in three subspecies. — The northern form is zestos Gray (3a). The male has always a red spot on the hindwing. In the female the band on the upper surface of the hindwing is bright red. South Mexico to Costa Rica. — tarquinius Boisd. occurs from Panama to Ecuador and North Venezuela.The upper surface of the hindwing of the male has mostly a red spot as in zestos, but the band on the under face is more obliquely placed. In the female the second white spot on the forewing is somewhat larger than in zestos, and the band on the under surface of the hindwing is nearer to the cell. — sesostris Cr. (female = tullus Cr.) (2d) has very rarely a red spot on the upper surface of the hindwing of the male, and the spots on the under surface are placed somewhat nearer to the margin. In the female the two white spots on the forewing are widely separated from the cell.
