Barber — Eggs of Three Cercopidce 
3 
Individual eggs are smooth, shining, slightly flattened, more 
than two times as long as wide, one end tapering, the other 
bluntly rounding; sides each convexly curved or with one side 
slightly incurved. They are light yellow in color, usually with a 
slight lemon tinge. 
Prof. Osborn (ibid 1916) described and figured the eggs of 
P. leucophthalmus Linn, dissected from the female adult. Our 
description nearly coincides with his.

iSince this paper has been in the hands of the publisher there has appeared a study of 
Philaenus linealus Linn., (Philip Garmon, Conn. Agri. Expt. Sta. Bulletin 230, in which the 
eggs are described.
