Expanse, 2.25 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 arise." 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.
