it was snugly curled, the long antennae, to my surprise, being 

 completely withdrawn. These two were all that could be 

 found on the bush. On August 15, Messrs. Schwarz and 

 Knab looked over this bush again, and collected all of these 

 locustids they could find. The next clay I examined the same 

 individual shrub and captured two more, which indicates that 

 in all probability the insects change quarters frequently and 

 that one night is sufficient time for them to become com- 

 fortably installed. 



On the same day an extended search, covering several 

 bushes of Staphylca, revealed Camptonotns in numbers. I 

 collected eight and could easily have secured a score. Three 

 of the eight were males, which, heretofore, have much more 

 rarely been collected than females. Carefully examining the 

 first pod in which a Camptonotns 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 visible within and scuttled 

 about when the pod was handled, but did not attempt to bolt 

 out like the first ones found, which probably were not spun 

 up. Several other pods were found to be similarly inhabited. 

 In some the opening had been closed by a well woven con- 

 tinuous sheet (see middle figure, Plate XXV). Apparently 

 nothing in the pods was eaten, they serving only as shelters. 



Some specimens of Camptonotus and twigs of Staphvlca 

 were brought home and the twigs placed in water under bell 

 jars. 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 ovipositor in the case of the females), with the mouth. Dur- 

 ing this process they showed wonderful control of the long 

 antennae, which after being pulled down one at a time by 

 the fore legs, by great muscular power at the base were slowly
