2 PHYSIOLOGY OF THE HONEY-BEE. 



are formed of hexagonal cells of various si^es. in v/hich the 

 bees raise theii* young and deposit their stores. 



4. In. a family, or colony of bees, are found (Plate 5) — 

 1st, One bee of peculiar shape, commonly called the Queen, 



or mother-bee. She is the only perfect female m the hive, 

 and all the eggs are laid by her; 



2nd, Many thousands of icorker-hees, or incomplete females, 

 whose office is, while young, to take care of the brood and 

 do the inside work of the hive; and when older, to go to the 

 fields and gather honey, pollen, water, and propolis or bee- 

 glue, for the needs of the colony; and 



3d, At certain seasons of the year, some hundreds and even 

 thousands of large bees, called Drones, or male-bees, whose sole, 

 function is to fertilize the young queens, or virgin females. 



Before describing the differences that characterize each of 

 these three kinds, we will studj^ the organs which, to a greater 

 or less extent, thej' possess in common, and which are most 

 prominently found in the main type, the worker-bee. 



General Characteristics. 



5. In bees, as in all insects, the frame-Avork or skeleton 

 that supports the body is not internal, as in mammals, but 

 mostly external. It is fonned of a horny substance, scientific- 

 ally called chitine, and well described in the following (juota- 

 tion : 



6. ''Chitine is capable of being moulded into almost every 

 conceivable shape and appearance. It forms the hard back of 

 the repulsive cockroach, the beautiful scale-like feathers of the 

 gaudy butterfly, the delicate membrane which supports the lace- 

 wing in mid air, the transparent cornea covering the eyes of all 

 insects, the almost impalpable films cast by the moulting larva?, 

 and the black and yellow rings of our native and imported bees., 

 besides internal braces, tendons, membranes, and ducts innu- 

 merable. The external skeleton, hard for the most part, and 

 varied in thickness in beautiful adaptation to the strain to 

 which it may be exposed, gives persistency of form to the little 

 wearer; but it needs, wherever movement is necessarv, to have
