ANATOMY OF THE HONEY-BEE 187 



occupies the greater part of the outer face of this 

 segment of the leg. In it the pollen is packed when 

 combed from the hairs, and transported to the hive. 

 The abdomen. — The abdomen is the last of the 

 three regions of the body. It consists of a series of 

 comparatively simple, overlapping segments, without 

 conspicuous appendages. 



II. INTERNAL ANATOMY 



Relative position of the internal organs, — ^As has 

 been shown in the preceding pages, the body-wall 

 serves as a skeleton, being hard and giving support 

 to the other organs of the body, which are con- 

 tained within it. 



The accompanying diagram (Plate XXV, 1), which 

 represents a vertical longitudinal section of the body 

 of the larva of an insect, will enable the reader to 

 gain an idea of the relative positions of some of the 

 more important organs. The parts shown in the 

 diagram are the follow^ing: The body-wall or skele- 

 ton {s); this is made up of a series of overlapping 

 segments; that part of it which is between the seg- 

 ments is thinner, and is not hardened, this remaining 

 flexible and allowing for the movements of the body. 

 Just within the body-wall, and attached to it, are 

 represented a few of the muscles (m) ; it will be seen 

 that these muscles are so arranged that the contrac- 

 tion of those on the lower side of the body would bend 

 it down, while the contraction of those on the oppo- 

 site side would act in the opposite direction. The 

 alimentary canal (a) occupies the centre of the body
