Form eriphyle, Edwards, yellow, not laved with orange, summer form. Expanse, inch, 50 mm. Albinos have been taken at Flathead lake on the west side and at Fish creek east of the range, with expanse of wings 52-55 mm. Early Stages—Egg .06 inch long, na-row, fusform. ribbed lengthwise, crossed by numer- ous striae; color buif-white when deposited, changing to crimson, then to black; mature larva from inches, 26-28 mm. in length, dark green, with band of pure white with crim- son line; chrysalis with anterior part and wing cases dark green, abdo- men yellow-green; the food plant is clover.
