1922] Barber — Eggs of Three Cercopidce 3 



Individual eggs are smooth, shining, sHghtly 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.
