INDUSTRY OF WASPS. 383 



During the whole of this day only four or five 



strange wasps 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 For comparison, it may be 



worth while to give one or two other cases. I will 



commence with tuat of a worker, I believe F. vulgaris, 



observed on September 19. 



10 A.M. I put her to the honey ; she fed and then flew 

 about the room, and at last got into my bee- 

 hive. 



10.54. She came in again at the window. I again put 

 her to the honey. She again flew all about 

 the room. 



11.41. She returned, and this time came to the 

 honey ; but when she had fed again flew 

 round and round the room, and did not seem 

 able to find her way out. I therefore put her 

 out. 



12.11 she returned, and the same thing happened again.
