Our most common representatives of the family are the insects 

 known as spittle-insects or frog-hoppers. During the summer months 

 one often finds upon various shrubs and herbs masses of white froth. 

 In the midst of each of these masses there lives a young insect, a 

 member of this family. In some cases as many as four or five in- 

 inhabit the same mass of foam. The froth is supposed to consist of 

 which the insect has pumped from the plant, by means of its 

 : urn. and passed through its alimentary canal. It is averted 

 that these insects undergo all their transformations within this ma-; 

 that when one is about to moult for the last time, a clear -j>a. 

 formed about its body: the superficial part of the foam dm 

 to form a vaulted roof to a closed chamber within which the change 



made. The adult insects wander about on herl 

 and trees. They have the power of leaping well. The name i 

 hoppers has doubtless grown out of the fact that formerly the froth 

 "frog-spittle," and was supposed to have been voided by 

 the tree-frogs from their mouths. The name is not, however, inap- 

 propriate: for the broad and depressed form of our more common 



mething like that of a frog. 



Our more common species of spittle-insects belong to the genus 



Aphrophora. They are mostly brownish insects, and are variously 



led and spotted. One of the common species of the Kastern 



tea is Af*h ?'( 'tphora quadrangularis (Fig. 147). The adult 



\S a brownish insect, densely cover 



with microscopic hairs, and black beneath; the \\ ing- 

 are marked with two oblique, brown bands, 

 which are confluent near the middle of the costal mar-
