further observations on their free behavior and take both. 

 The spider showed signs of life for three days. 



Long afterward, another wasp was found actively en- 

 gaged in running about on a fallen log. Suddenly it leaped 

 to the ground and chased a medium-sized spider. The arach- 

 nid made one leap and escaped. The wasp became frantic; 

 the sight of the spider and the fact that she had been fooled 

 so excited her that she acted as though mad, walking, flying, 

 running about the ground in indescribable directions until 

 she tumbled headlong into a mole's hole. After a few mo- 

 ments she emerged from the burrow carrying a spider by its 

 anus. She walked forwards, backwards or sidewise over the 

 ground or low vegetation, in a manner indicating intense 

 excitement, and eluded us many times before we finally 

 captured her. All this occurred, not in the hot sunshine 

 where most Pompilids choose to work, but on a path in. the 

 cool, shady forest.
