FOOD OP INSECTS. 143 



Aristotle was shrewd enough to perceive this diffi- 

 culty, when he says of such insects (JJymenoptera) 

 that they have teeth, not for feeding but for fulfilling 

 other instincts*, such as building cells of wax, and 

 similar materials. In the systems, however, founded 

 on Clairville's arrangement, bees and other insects of 

 the same order are classed among eating insects. As 

 it would not suit the design of our little work to throw 

 in the way of the reader any difficulties of this kind 

 which we can avoid, we shall follow a hint thrown out 

 by Kirby and Spence t, and consider them under the 

 three-fold division of eaters, lappers, and suckers, 

 though plausible objections, we are well aware, may 

 be made to this, as well as to most other arrangements.
