. The butterfly book; a popular guide to a knowledge of the butterflies of North America. Butterflies. Genus Eresia Genus ERESIA, Doubleday Butterfly.—Small butterflies, closely resembling the species of the genus Phyciodes in the neuration of the wings, and only differ- ing from them in the outline of the outer margin of the primaries, which are more or less excavated about the mid- dle. In the style of the markings they differ somewhat widely from the butterflies of the genus Phyciodes, notably in the absence of the crescents on the margins of the wings. The wings on the upper side are generally some shade of deep brown or black, marked with spots and bands of white or fulvous, the median band on the hind wings being generally more or less conspicuous. In the Fig. 93.—Neu- pattern of their markings they illustrate a transition ration of the genus from the genus Phyciodes to the genus Synchloe. enlarged. s s y Egg.—Hitherto undescribed. Caterpillar.—Cylindrical, with seven rows of spines, one dorsal, and three lateral on each side; the spines are short, blunt, and armed with short bristles. The head is subcordate, with the vertices rounded. It moults four times. Chrysalis.—Cylindrical, abdomen stout, head-case short, bev- eled, nearly square at top, the vertices pyramidal. There are three rows of small tubercles on the dorsal side of the abdo- men. The caterpillars so far as known feed upon various Cotnpositce, as Diclippa and Actinomeris. The genus, which is somewhat doubtfully separable from Phy- ciodes, and probably possesses only subgeneric value, is well represented in Central and South America. But three species are found in the faunal region of which this book treats. (1) Eresia frisia, Poey, Plate XVII, Fig. 42, $, (Frisia). Butterfly.— Upper side reddish-fulvous, clouded with fuscous at the base. On the basal area are waved black lines, separate on the hind wings, more or less blended on the fore wings. The outer border is broadly black. Betwee
