Butterfly.--The wings in both sexes are variable pale blue, dusky on the margins, with white fringes checkered with dusky at the ends of the veins. On the under side the wings are dark gray, profusely spotted, the most characteristic markings being a white ray in the cell of the hind wings, a broad submarginal band of white arrow-shaped markings on both wings, with a black spot at the tip of each sagittate maculation and a dark triangular shade between the barbs. These markings are not shown as they should be in Plate XXX, Fig. 44. They are only faintly indicated. Expanse, 1.25-1.30 inch.

Early Stages.--These await description.

This butterfly ranges from Oregon to Mexico, and eastward as far as Colorado on the mountains.
