84 STATE BOARD OF AGRICULTURE. 



Family MEMBRAOIDiE. 



Contains the "tree-hoppers," which are odd-looking creatures, more or less 

 wedge or beech-nut-shaped, the prothorax often abnormally developed into 

 horns spines, crests or otherwise. They leap and fly quite readily and are 

 commonly found on trees and shrubs. Most of the species are rare and cause 

 little or no injury, some envelop themselves in frothy masses, and some excrete 

 honey-dew. 



The only injury that is really notable in New Jersey is caused by the Buffalo 

 tree-hoppers or species of Cerasa, which lay their eggs in slits made on fruit 

 trees. This seems to cause a poisoning, the slits form open wounds, checking 

 growth and forming a weak point on a young tree or branch. 



Careful pruning to cut out the egg punctures, the cuttings to be afterwards 

 burnt, will usually avoid injury. Insecticides are not indicated.
