Rh wings have two linear narrow tails towards the anal angle. P. Marsyas is a native of Brazil, Guiana, and some other countries of South America. It is greenish-blue on the upper side, changing with the direction of the incident light into violet, the costa and apical angle of the upper wings widely black. Beneath the colour is lilac, glossy, with seven or eight small black spots, surrounded by a white circle, scattered over the disk of each wing; the anal angle bluish-green, with two short white transverse streaks and two pretty large black spots; tails black with the extremity white, the outer one about half the length of the other. Body blue above and whitish beneath. The antennæ, as in most of the Polyommati, are black with pale rings.
