Butterfly.—The sexes are much alike in this species, which ranges widely over the Southern States, and is found even in south- ern Illinois and sometimes still farther north. Expanse, inches. Early Stages.—These have been fully described by various authors, most carefully by Edwards. Genus COLIAS, Fabricius (The Sulphurs) " Above the arching jimson-weeds flare twos And twos of sallow-yellow butterflies, Like blooms of lorn primroses blowing loose, When autumn winds ; JAMES WHITCOMB RILEY. Butterfly.—Medium-sized butterflies, yellow or orange in color, with' black borders upon the wings. In many species this border is heavier in the female than in the male. Egg.—The egg is spindle-shaped, thickest at the middle, taper- ing at the apex and at the base, generally attached by an enlarged disk-like expansion to the point on which it is laid. The upper extremity is rounded; the sides are marked by small vertical ridges, between which are delicate cross-lines. Caterpillar.—The caterpillars strongly re- semble in appearance those of the preceding genus, from which, superficially, they cannot be distinguished by any anatomical peculiar- ities. They feed upon Leguminosce, and espe- cially upon clover (Trifoliuni). Chrysalis.—The chrysalids do not generally differ in appearance from the chrysalids of the genus Meganostoma, though the wing-cases do Colias. 289.
