It will be seen that the intervals af her absence were remark- 

 ably regular. On one occasion, indeed, she was only away fouF

The number of visits was iifty-one in eleven hours and a half.

 came to the honey. 



As regards the regularity of their visits, and the time occupied, 

 other wasps which I observed agreed very closely with this one.
