38 GRAMMAR OF ENTOMOLOGY. 



115. The egg which is first deposited will of 

 course be the first to hatch, and become the first 

 maggot ; the first maggot will first become a 

 chrysalis, and will also undergo the final change 

 sooner than the younger part of the brood above. 



116. To guard against the confusion which 

 rnust necessarily arise from this, she continues 

 the hole, changing its direction, until it assumes a 

 horizontal course, and at length arrives again at 

 the outside, — thus leaving an easy escape for the 

 first of the brood, without disturbing those above, 

 which will not appear till four or five days later. 



117. She now closes the hole just above the 

 lower bend with a partition consisting of fine 

 sand, firmly glued together by means of a viscid 

 saliva, with which she is copiously furnished : 

 having stored a sufficient quantity of food, which 

 consists of pollen, from the anthers, and honey from 

 the nectaries of flowers, for the support of one 

 larva, she deposits an egg, and then closes the 

 cell in the same manner as she formed its bottom. 



118. She then stores up more food, deposits 

 another egg, and closes up another cell, pro- 

 ceeding thus until she has quite filled the 

 perpendicular part of the hole. Her task now 

 draws to a conclusion ; she has only to close the 

 two apertures : the lower one, intended for the 

 outlet, is merely closed in the same way as 

 the cells, with very fine sand ; but as the upper 

 one is much more exposed to danger from rain,
