v, fig. 14, (AA is the gallery and B is a break in it) 

 and fig. 15, the gallery separate. The bees, having 

 discovered the presence of the worm, immediately set 

 to work to remove it, together with its silken shroud. 

 If not caught and carried out by the bees, it drops 

 down on the bottom board, and seeks a corner or 

 crevice in which to spin a cocoon to protect itself 

 while undergoing the transformation from the worm 

 to the moth. (See plate vi, fig. 16, showing the worm 

 during its first stage of growth, also after having 

 nearly completed its cocoon ; fig. 17, pupa in the ad- 

 vanced stage, also cocoon from which the moth has 

 emerged.) 



Each young bee over which the worm extends 

 its gallery, is either killed or mutilated, and is car- 

 ried out of the hive by the bees. 

 . Sometimes the worms penetrate to the center of 

 the comb containing brood, and there form galleries, 

 entangling the young bees so that they cannot get 

 free from it. The worker bees discovering this, imme- 

 diately detach a portion of the comb, together with 

 the young bees and worms, which falls to the bottom 

 of the hive, there, perhaps, to form the nucleus of a 

 web soon to entangle and destroy the whole colony. 

 When enough worms are present to cause the bees 

 to abandon the portion of comb occupied by them, 

 they spin innumerable threads, extending in every 

 direction, enveloping the comb in a thick net-work. 

 This is extended on all sides, and securely attached 

 to the top and walls of the hive it then serves, also
