306 THE SECRETARY ON ADDITIONS TO THE MENAGERIE. 



needs of the grub which will develop from the egg laid upon 

 its surface. This done, the little chamber is sealed up, and the 

 process again repeated. 



During the numerous foraging expeditions necessary for obtain- 

 ing sufficient pollen and nectar for the sustenance of her future 

 broods, no care is taken to protect the burrow, a fact of which 

 advantage is occasionally taken by a Nomada bee, too lazy herself 

 to build nurseries or to gather stores of food. Waiting therefore 

 till the rightful owner has set out on her travels, the " cuckoo " 

 bee slips in and deposits an egg on any pellet of food of adequate 

 size not yet sealed up. 



The Andrena bee not infrequently appears to experience con- 

 siderable difficulty in recognizing her own burrow, as she may 

 often be seen to tentatively explore the entrance to several before 

 suddenly diving down her own. Marking the bee with a little 

 powdered chalk as she leaves her burrow will render it easy to 

 recognize the rightful owner on her return. 



The burrowing bee having finished her labours underground 

 does not take the precaution of closing up the mouth of the 

 burrow, but on her death, within about a month from emergence 

 from her winter quarters, leaves it to be gradually obliterated by 

 the levelling of the mound outside under the influence of rain 

 and wind.
