times on the tender tissue of the stem. During the last few days of 

 July and the first three weeks of August, adults appear and eggs are 

 again deposited. Most of these hatch by the last of August and by 

 the middle and last of October the larvae are full grown and have 

 sought hibernation quarters. In addition to feeding on the foliage 

 the larvae also roll the leaves from the edge toward midrib. Usually 

 one side only was rolled, but sometimes both. In a very few cases 

 the leaves were rolled from the tip downward toward the middle. 



As a rule the method of procedure was as follows: The larva 

 resting on the blade of the leaf would crawl out on the petiole for 

 about one quarter of an inch from the base and bite through the 

 petiole until the leaf hung only by a few strands of tissue. This 

 caused the leaf to wilt gradually, making it more flexible and easier 

 to roll. The larva then would roll the leaf from the outside, fasten- 

 ing it with several strands of silk. Inside these rolled leaves, which 

 later became very dry and brittle, were found larvae in all stages and 

 pupae. The curled leaves finally drop to the ground and on several 

 occasions pupae were found in them. 



Pupation evidently takes place in the curled leaves either on the 

 plant or on the soil. According to Busck, the cut leaf dries up and 

 crumples, but in New Jersey, however, we found that they were 

 rolled and fastened by the larvae. The larvae are very active when 

 disturbed in their shelters and elsewhere and wriggle violently in 

 their efforts to escape. The second brood of larvae confine their 

 feeding mostly to the young leaves, the stem tissue near the tip, and 

 the base and surroundings of the seed capsule. On October 24 at 

 Rutherford, partly developed and full-grown larvae were observed 

 in the dried seed capsules. Some had eaten their way into the base 

 of the capsule inside the calyx. Some were found in the bottom of 

 the capsule in one of the four divisions, together with partly eaten 

 seeds. Others were found under the somewhat dried stem tissue at 

 the tip of a shoot. In every case, the material around the larva was 

 somewhat webbed up and it is evident that the places where they 

 were found had been selected as hibernation quarters.
