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 species.

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 reveal the influence of the Heliconians,
