THE BEE. 



In common with insects generally, tlie chief parts of the mouth 

 are, the tongue, ihejaws, the lips, and the throat or oesophagus. 



The jaws are each douhle, separated by a vertical division. 

 Each pair opens, therefore, with a horizontal instead of a vertical 

 movement like the human jaws. The pair of upper jaws are called 

 mandibles, and the lower maxillcs. The upper lip is called the 

 labrum and the lower the labium. The mouth is also supplied 

 with two pairs of special organs called palpi or feelers, one pair 

 attached to the lower lip and called labipalpi, and the other to the 

 lower jaw and called maxipaJpi.

 of the wUd bee {Anthophora retusa),* the parts being indicated.
