in late summer and are gregarious, spinning a silken tent 

 in which they pass the winter; in the spring they scatter 

 and become full grown by June. The chrysalids have a 

 rounded head, sharp tubercles on their backs, and are 

 whitish with dark and orange markings. 



Resembles Phyciodes nycteis on the 



ehtaea upper side, but the underside is darker and 



harnsi 



has a continuous row of silver spots along 



the outer margin of the hind wings. The larvae feed on 

 the aster, Doellingeria umbellata; they are reddish with a 

 black stripe down the middle and nine rows of black, 

 branched spines. 



The species of Grapta are called Angle- wings; they "look 

 as if Mother Nature had with her scissors snipped the 

 edges of their wings, fashioning notches and points accord- 

 ing to the vagaries of an idle mood." They are tawny, 

 with darker markings above, and below there is a combi- 

 nation of brown and gray which corresponds closely with 

 the color of dead leaves. The chrysalis has a forked head 

 and a prominent tubercle on the back of its thorax. All of 

 the species hibernate as adults, hidden in hollow logs and 

 similar places.

 some other question on his mind when he named the species 

 inter rogationis. It is also called Violet-tip, because of the 

 violet Papilio-like tail. The summer form (utnbrosa) 

 has the dark markings on the upper side "clouded." 

 Plate XXX shows the winter form, fabricii. The larva feeds 

 chiefly on hop and elm ; it has a pair of branched spines on 

 the tip of its head and others on its body; it is chestnut- 

 colored with light dots in longitudinal rows. Like other 

 Grapta larvse, it frequently cocks its head when not feeding. 

 The chrysalis, which is the color of dead leaves, is very 

 angular and has a "Roman nose" on its thorax; in addi- 

 tion, the thorax bears one or more pairs of metallic silver 

 or gold spots.
