THE BEE. 



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

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



The jaws are each double, 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 maxilla. The upper lip is called the 

 Idbrum 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 Idbipalpi, and the other to the 

 lower jaw and called mafipalpi.
