an 1 shorter thread. Finally, after much labor, the j'oung 

 caterpillar (for it begins its work soon after hatching from 

 the egg) spins a number of threads, each of which adds new 

 strength to the tubular structure, until a tent arises — the 

 whole the work of perhaps but a few minutes. In this tent 

 it resides, enlarging it as its body grows, and eating out the 

 interior, adding new stores of food by sewing new leaves to 

 the outside of the tent, until, when about to pass into the 

 chrysalis state, it stops eating. It does not now desert its 

 home. Its tent serves it as a rude cocoon, the caterpillar 

 having previously lined it with silk, and we often find the 

 end of the chrysalis protruding out of the door of the tent 

 after the moth has flown away. p^^ ,_ 



This species of leaf-roller, called Lozotcenia rosa- 

 ceana by Dr. Harris (Fig. 47, enlarged twice), is 

 rather large compared with others of its family, its 

 body rather plump and pale livid green, its head is 

 black, as is also the ring following, while the other 

 segments are transversely wrinkled above, with a few 

 scattered fine hairs. The moth itself usually appears 

 about the last of June. From its eggs laid at this 

 time a new brood of worms appear in August. The ^^af- 

 pupa or chrysalis is pointed on the top of the head, 

 and on the hinder edge of each abdominal ring are two rows 

 of spines. The moth is pale brown, with two broad oblique 

 darker reddish brown bands across the fore wings, and a tri- 

 angular spot of the same color near the tip. The hind 

 wings are ochreous yellow. The wings expand abont an 

 inch, and the caterpillar is a little less than an inch long. 

 There are many other leaf-rolling caterpillars Avhich roll up 

 leaves much more perfectly than the Garden Leaf-roller. 

 No one has described their mode of building their tubular 

 houses l)etter than the celebrated French philosopher and 

 naturalist, Reaumur. "VVe may find on some of our trees 

 leaves rolled up much like those here figured from Reau-
