Male. Characterized by thle broad black outer border on the upper-side of both wings, this border being frequently 2 mm. in width. The blue color on the remaining wing-area is very deep, and, although quite shiny in certain lights, is more the color of P. icnrioides, and much darker than in the other western races. On the underside the black spots are very large, and prominently white-ringed; the ground color is a deep gray-brown, rather reminiscent of the type form and darker than is usual in the Coloradan oro Scud. Fringes white.
