removal gave great relief to the other wasp, as was 

 manifested by an entire change of manner. Before, she 

 had been constantly on the lookout, moving only with

 vigilance. With the Ceropales in our vial we, too, felt 

 relieved, and now the path of discovery seemed clear 

 before us ; but scarcely had things assumed their old 

 status when a second enemy, a much larger and bolder 

 Ceropales, threw both the Pompilus and ourselves into 

 consternation. Again we took the side of our wasp and 

 drove the other one off, but only to see it return a few 

 moments later. The Pompilus now flew at it in a most 

 gallant fashion and pursued it far afield, but when she 

 came back the enemy was but a few seconds behind 

 her. Here we again interposed and removed the second 

 Ceropales from the field of action. 



All cause for anxiety being over, the wasp now re- 

 sumed her journey. Before long she came to a shallow 

 depression in the ground which was partly sheltered by 

 an overhanging lump of earth, and under this covering 

 she dropped the spider and again began to squeeze its

 manipulation. Next, her toilet was attended to, and 

 then the spider was carried back and placed again
