NymphalinEe (the Nymphs) border scalloped or tailed; the inner border always affords a channel for the reception of the abdomen. The costal nervule invariably terminates at the external angle of this wing. The discoidal cell is frequently open, or simply closed by a slender veinlet, which it is not always easy to detect; the anal vein is never lacking. The fore legs are greatly reduced in the male, less so in the female. Egg.— The egg is either somewhat globular, or else barrel- shaped, with the sides marked with net-like elevations, or verti- cally ribbed (see Figs, i, 8, 10). Caterpillar.—When first emerging from the egg the caterpillar is generally furnished with long hairs rising singly from wart-like ele- vations which are arranged either in longitudinal rows or in geo- metric patterns (Fig. 85). As the caterpillars pass, their successive moults the hairs are transformed into branching spines or tubercles (see Plate III, Figs. 28-38). Chrysalis.—The chrys- alis invariably hangs sus- pended from a button of silk, and is frequently furnished, especially on the dorsal or upper surface, with a number of prominences; the head is usually bifurcate, or cleft (see Plate IV, Figs. 21, 39, etc.). This is the largest of all the subfamilies of the butterflies, and is widely distributed, including many of the most beautifully colored and most vigorous species which are known. There are twenty-six genera represented in our fauna, containing about one hundred and seventy Fig. 85.— Caterpillar of Vanessa autiopa, just hatched. (Greatly magnified.) (After Scudder.) Genus COLirENIS, Doubleday Butterfly.— Butterflies of moderately large size, the fore wings greatly produced and relatively narrow; the hind wings evenly rounded and relatively small, of bright reddish-brown color, with darker markings. The species are mimics, and in the elongation of their wings
