THE ENEMIES OF THE OBTHOPTERA. 175 



As soon as she had opened up the way she began to hunt 

 about as before, running hither and thither with great rapidity 

 and showing by the excitement of her manner that some im- 

 portant erisis ia her affairs was at hand. After three or four 

 minutes she stumbled upon a large dirt-colored locust (Disos- 

 teria Carolina), which was lying on the ground about two feet 

 away. She seized her bulky prize by the base of the antennae 

 and carried it, right side up, to the edge of the hole, where it 

 was dropped while she backed in. Then, grasping it in her 

 mandibles, she dragged it out of sight. When she reappeared 

 we tried to catch her, and she flew away. A few minutes later 

 she returned and began to fill the hole but again we disturbed 

 her, and this time she was, perhaps, impressed with the idea of 

 danger, for she stayed away from the place for at least half an 

 hour. At the end of this time we gave her up and turned our 

 attention to something else, but when we came back later in the 

 day we found that the hole had been filled and the spot neatly 

 smoothed over. "We dug out the locust and found the long 

 cylindrical egg fastened on the right side, just above and over- 

 lapping the articulation of the third leg with the body. The 

 locust was quiet but the abdomen pulsated and under stimula- 

 tion the antennae quivered. By the next day it had partly re- 

 covered, and from the seventh to the tenth of July it was quite 

 lively, kicking vigorously when touched. On the eleventh 

 it began to lose strength and on the fourteenth it died. The 

 egg never hatched.
