AN ORTHOPTEROUS LEAF-ROLLER. 

 By A. N. CAUDEI.L. 



Early in July, 1900, while collecting in the vicinity of Wash 

 ington, D. C., I found a small papaw leaf neatly rolled by some 

 insect. Upon opening it I was surprised to see a very small 

 apterous orthopteron leap actively out, losing itself immediately 

 among the leaves on the ground. On close search I found on 

 the same plant another exactly similarly rolled leaf. Upon peer 

 ing into this very cautiously I found that it contained a specimen 

 like the one just lost. From an examination of the specimen 

 within the case I could only determine that it was a delicate, 

 pale colored Locustid with very long slender antennae, apparently 

 a very young specimen. This was preserved, but, not being at 

 that time interested in Orthoptera, 1 made no notes, nor did I 

 then know that the leaf was rolled by this insect. 



On May 22, 1902, Mr. Busck handed me a small jar contain 

 ing some bits of willow bark and two Locustid nymphs. Upon 

 closely examining the material I found three eggs in a crevice in 

 a piece of bark, two empty, obviously those from which the 

 nymphs had issued, and one shriveled up, evidently destroyed 

 by fungus. The nymphs were identified as those of Campto- 

 notus carolinensis Gerst. The piece of bark containing these 

 eggs was taken about two feet above ground from a large tree. 

 Placing one of these nymphs in spirits I enclosed the other in a 

 glass tube with some willow leaves covered with plant lice. On 

 examing this tube the following day I found the insect had con 

 structed for itself a pocket in one of the leaves, and then I recog 

 nized without doubt the same insect I had taken two years before 

 on papaw. The pocket was made by cutting the leaf through 

 on each side to the midrib and at right angles to it and again one- 

 third of an inch further along the midrib, this time the incision 

 being formed at an angle with it. The flaps thus formed on either 

 side were then folded together and their edges fastened together 

 with silk-like strands, and I have subsequently seen cases with
