The fore wings are often somewhat falcate. They are largely an Old World type but the north temperate zone of the New World pos- sesses two or three genera, but none peculiar to it. A single form is found in New England. "Woods and their outskirts are the favourite haunts of the species . . whose .light is commonly more rapid and long sustained" than that of the Pieridi (Trimen). Excepting by Iliibner, no naturalist has before separated this group as one of equivalent value to the Pieridi and Rhodoceridi. The different gen- era have usually been tiassed with the former, midway between which and the latter they really belong. The study of tlie early stages, however, will speedily convince any one free from the bias of tiadition that the sep- aration we here nuiintain is well founded. The butterflies of this rather small group, like those of the next tribe, are white marked with black, but they are usually further characterized by "a more or less triant^ular large patch of bright colour occupying the apical portion of fore wings. The colour of this apical marking is most commonly some shade of bright red or orange, often with a lovely rosy gloss" (Trimen, Rhop. Afr. Austr., 42). This bright colored patch is often confined to tlie males. It has been suggested on several occasions tliat the marbled green mottling of the under surfvce of the wings, also characteristic of this group of butterflies, has for its purpose the better con- cealment of the insect, as assimilating it to the color of the plants or flow- ers on which it accustomed to alight; and Kirby suggests that the frequent absence of tiie orange spot from the tip of the female may be due to its greater need of protection than the male, since this vivid spot would render it too conspicuous; while its absence vvoidd ren
