604 FAMILY VII. TETTIGOXIID.E. THE CAMEL CRICKETS. 



leaf being folded back, thus making the terminal cuts unnecessary. Some- 

 times the pocket is formed altogether on one side of the midrib. 



"When supplied with fresh leaves the insect at once commenced making 

 a new house, cutting with its mandibles incisions from the edge of the leaf; 

 then grasping the thus movable edges each with the three legs on each side 

 and forcing them together, it spun what was apparently silk thread from 

 the mouth, fastening the edges together. The whole performance did not 

 take five minutes after it was begun. The insect accurately measured the 

 proper places for the cuts by placing itself on the leaf and realizing how 

 much was needed. This being determined, the work went on rapidly. 

 Within these pockets the nymphs live, coming out mostly at night to feed 

 on plant lice, which seem to form their entire food supply during their 

 early life." 



McAtee found G. carolinensls in numbers in August on IMum- 

 mer's Island, Md., inhabiting the fruit pods of the bladder-nut, 

 titaphylea trifoliata L. Of its habits he says:

(A'fter McAtee.) 



"Carefully examining the first pod in which a Camptonotus was found, 

 it was seen that as usual, a large irregular opening had been made in one 

 of the cells, but it had been closed by a loosely constructed door, composed 

 of bits of the pod and a network of fine spun silk-like threads. The locustid 

 was snugly curled within, the long antennae, to my surprise, being com- 

 pletely withdrawn. It scuttled about when the pod was handled, but did 

 not attempt to bolt out. Several other pods were found to be similarly 

 inhabited. 



"Some of the insects and twigs of Staphylea were brought home and 

 in a large jar two females and one male were confined with a twig bearing 

 several entirely uninjured pods and many leaves. They were watched for 

 some time by a light but did nothing with the plant. They sometimes 

 moved nervously about, sometimes sat motionless, but they also spent 

 much time cleaning all accessible parts of the body (even including the ovi- 

 positor in the case of the females), with the mouth. During this process
