 and pebbles brought from a little distance, very much 

 as is done by Ammophila. 



When we found that quinquenotatus was a very com- 

 mon species, and that nearly every day brought us a 

 fresh example, we thought that we had the question 

 of its stinging habits in our own hands. What could 

 be easier than to carry a strix about with us and to ex-

 Fabre and Marchal from this manoeuvre made us con- 

 fident of success. We did not doubt that when the wasp 

 came for her spider and found it livelier than it ought 

 to be, she would repeat the stinging operation before 

 our eyes. 



Accordingly, the next time that we saw quinquenota- 

 tus digging we made a diligent search for her spider, 

 and soon found it on a bean plant five feet away. Just

 and carried it to some purslain, close to the hole, where 

 she hung it up again, while she went to make her final
