Butterfly.--The butterfly in both sexes somewhat closely resembles P. phaon on the upper side. On the under side the fore wings are red on the median area, with the base, the costa, the apex, and the outer margin pale yellow; the black markings very prominent. The hind wings on the under side are nearly immaculate yellow. Expanse, male, .80-1.10 inch; female, 1.10-1.25 inch.

Early Stages.--These may be found described with minute exactness by Mr. W. H. Edwards in the pages of the "Canadian Entomologist," vol. xvi, pp. 163-167. The egg is yellowish-green. The caterpillar moults five times. When mature it is about six tenths of an inch long, armed with seven principal rows of short spines, which appear to vary in color in the spring and fall broods, being light brown in the June brood and greenish-yellow in the October brood. The prevalent color of the caterpillar is some shade of yellowish-or greenish-brown, mottled with lighter and darker tints. The chrysalis is yellowish-brown. The food-plants of the caterpillar are various species of aster.

This species is found as far north as Nebraska, and is abundant in Colorado and New Mexico, ranging southward through Arizona into Mexico.
