_Junonia coenia_, the Peacock butterfly, is a medium-sized butterfly with an expanse of about two and one-fourth inches. The large eye-spots on both wings give it a characteristic appearance, very different from any other butterfly in this country. It occurs in all parts of the United States, but is somewhat rare in the northern part of its range. The dark green eggs are deposited on various kinds of plantain; the caterpillar is dark and covered with spines; the chrysalis generally light brown, and has a conspicuous depression in the ventral thorax. This butterfly is conspicuous for its pugnacity; it will drive away any other species which chances to approach, and even dart at stones or other objects thrown in the air. _Basilarchia disippus_, the Viceroy butterfly, looks very much like _Anosia plexippus_ the Monarch, except for a single transverse black band on the hind wings. The eggs are laid upon willow or poplar leaves; the caterpillar has no spines, but there are two club-shaped appendages just back of the head; the chrysalis is light gray with brown spots, and has a fin-like projection on back of the thorax. The Viceroy spends the winter in the larval state. When cold weather sets in the caterpillar anchors a leaf to the twig by means of silken threads, then rolls himself up in the leaf and sleeps until the following Spring. _Chlorippe celtis_, the Hackberry butterfly, is smaller than most of the common four-footed butterflies, its expanse being less than two inches. The general color of the wings is gray, but the outer part of the fore wings is black with broken rows of white spots. There is a little red tinge about an eye-spot in the fore wing, and five such spots are located near the outer edge of the hind wing. The female is slightly larger than the male, and somewhat less pronounced in color. The eggs are deposited in clusters on the hackberry trees; the caterpillar bears a pair of antler-like appendages on its head; the chrysalis is stockily built, with the head deeply notched. The Hackberry butterfly is found in all the Southern States east of the Rockies, and has been reported as far north as southern Pennsylvania. It is double-brooded in the middle west, the last caterpillars hibernate and do not reach maturity until the next year. THE SATYRINAE The members of this subfamily are medium-sized, obscurely colored, forest-loving butterflies, conspicuous because of their peculiar manner of flopping about in the grass and low herbage.
