52 BRITISH CICADA. 



yellowish tuft between the two brown lateral plates. 

 Elytron yellow, longer than the abdomen, and fur- 

 nished with five apical and three discoidal areas, which 

 are feebly fuscous-brown. Elytron sometimes marked 

 with an apical dark stripe. Nervures, if visible, 

 whitish. Legs pale and ochreous. Hind tibiae each 

 with a fine dark inner stripe. 



This insect is generally distributed, and rather 

 common. Varieties occur in which the inner elytral 

 areas are nearly filled with black. Mr. Edwards 

 remarks that individuals taken in salt marshes are 

 smaller, and that their elytra are scarcely as long as 

 the abdomen.
