pattern of hind wing which I have illustrated (Fig. 42, A), the female 

 has the marks more or less obsolete, and the general tint deeper and 

 more uniform. The species extends farther north and east than Ly- 

 oaon ; but in the Mississippi Valley and the more southern States, 

 both species occur, and I have often found their larvfB feeding on the 

 same tree. Herse is, however, less common than Lycaon. Boisduval 

 gives Primus as food-plant of the species, but it has never been since 

 recorded as occurring on trees of that genus, and Mr. Samuel H. 

 Scudder, of Plymouth, N, H., to whom I sent young larva?, found they 

 refused plum-leaves, and died rather than eat of them. 



The eggs of Herse (Figs* 

 41, rt, and 42, p)^ unlike 

 those of its lesser congener, 

 are invariably deposited in 

 dense batches of from 300 

 to 500, and two, or more of- 

 ten three, tiers deep. Oth- 

 erwise they differ from 

 those of Lycaon mainly in 

 being a little broader on 

 the crown. When first laid

white, but toward hatching, the mass, if uninjured, acquires a deeper 

 buff color. The larva, in the first stage, is easily distinguished by its 

 copal-yellow, instead of black, head; and in the other stages by hav- 

 ing a dark medio-dorsal line, and a straight, instead of a wavy, supra- 

 stigmatal line. The head is also larger, more pubescent, broader at 

 top, and with the antlers larger, more spiny, and more hairy. The 

 spines vary somewhat in sharpness and size, but are often very con- 

 spicuous in the third molt, when a worm at rest presents a really sin- 

 gular appearance (Fig. 42, y). These larvaj are more or less gregarious 

 up to the third molt, after which they scatter. The habit, after they 

 scatter, of hiding within leaves drawn around them, is more deter- 

 mined than in Lycaon ; and the young of the second brood fall with 

 the leaf, and hibernate huddled together in companies of five and up- 

 ward (Fig. 42, q). They have a habit, before separating, of feeding 

 side by side, eating the leaf from the tip downward, but leaving the 

 stouter ribs. Spinning a thread wherever they go, thej^ often, in 

 traveling from leaf to leaf, make quite a pathway of silk ; and if the 

 branch be suddenly jarred, they will drop and hang suspended in 

 mid-ail'; and, after reassurance, climb up again with the thoracic legs.
