pressions behind margins; lateral margins nearly parallel, longer than short 

 diameter of eye; elytra not quite twice as long as wide, outer margin flaring, 

 apex angulate; abdomen broadly triangular, about as wide as long, margins 

 and apex greatly exceeded by wings.

LIFE HISTORY. 



HISTORY. 



Life history notes on the Cercopidae are rather limited. Osborn 

 (1916) made some valuable studies of the life histories of Maine 

 froghoppers, but gave no complete history, including the egg stage 

 and five nymphal stages, of any one species. He figures and de- 

 scribes three instars of Lepyronia quadrangularis. In 1921 Garman 

 published the life history of Philcenus lineatus (Linn.), wherein he 

 describes the egg and four instars. Later Barber and Ellis (1922) 

 described the oviposition of three species, Philcenus lineatus (Linn.) 

 and Philaroiiia bilineata (Say.) The most complete study of a cer- 

 copid life history is that of a foreign form, Tomaspis varia, which is 

 a pest of sugar cane in Trinidad (Urich, 1913). Garman (1923) 

 gives a complete description of the life history of Clastoptera obtusa 

 (Say) and a brief description of the egg stage of Lepyronia quad- 

 rangularis (Say). 



DISTRIBUTION. 



Lepyronia quadrangularis (Say), according to the Snow collec- 

 tion, has been taken from four counties in Kansas, namely, Chero- 

 kee, Douglas, Neosho, and Doniphan. It is also recorded here from 

 Atherton, Mo. Ball (1898) lists it from Ontario, New Hampshire, 

 New York, Pennsylvania, Connecticut, District of Columbia, Mary- 

 land, West Virginia, Georgia, Florida, Mississippi, Ohio, Iowa, 

 South Dakota, Nebraska, Colorado and Texas. Van Duzee lists it 

 from Muskoka lake district of Canada, Lake Temagami, Ontario 

 and Quinze lake region. Comstock says it is one of the most com- 

 mon spittle bugs of eastern United States.
