TABLE VI.— FAMILIES OF THE PHYTOPHAGA 



This series includes three families, which are so connected by intermediate 

 forms that it is not easy to separate them. The following table will aid the student 

 in separating the more typical forms. 

 A. Body elongate; antennae almost always long, often as long as the body or 



longer. The larvae are borers, p. 524 CERAMBYClDiE 



AA. Body short and more or less oval; antennae short. 



B. Front prolonged into a broad quadrate beak; elytra rather short so that 

 the tip of the abdomen is always exposed. The larvae live in seeds, p. 535 



Mylabrid^. 



BB. Front not prolonged into a beak; usually the tip of the abdomen is 

 covered by the elytra. Both larvae and adults feed on the leaves of plants, 

 p. 530 Chrysomelid.?!; 



TABLE VII.— THE FAMILIES OF THE RHYNCHOPHORA 

 {Compiled from Blatchley and Leng) 



A. Beak rarely absent, usually longer than broad; tibice never with a series of 

 teeth externally.
