It is used for gathering pollen, and the tibia, the lowest seg- 

 ment of the same leg, is used as a basket to carry the pollen 

 to the hive. It is provided with long curving hairs for that 

 purpose. Bees are frequently seen in the field or coming 



home to the hive, with their pol- 

 len baskets filled with golden 

 dust. 



The wings of bees are very

 a hairy, hollow tongue, adapted for sucking or lapping up the 

 nectar of flowers. It lies between the second pair of maxillae. 



The bee, as is well known, is provided with a formidable 

 sting. This is a modification of the ovipositor. Connected 

 with the sting is a poison-gland from which the bee injects 

 into the wound formic acid, which causes an irritating in- 

 flammation. 



The above description applies to the worker-bee. There 

 are two other forms, the queen and the drone. The drones 

 are the males, and can be distinguished by their greater 

 plumpness and hairiness. The queen is the mother of the 

 drones and of the workers, and has a body which is longer
