wounds made also doubtless furnish good points of entrance for cer- 

 tain fungous diseases. 



Cases are on record also where the buds of certain trees were 

 seriously injured by the deposition of eggs within them. Damage 

 from such oviposition always results when eggs are deposited deeply 

 in small buds. In this respect the species concerned most fre- 

 quently are Ceresa taurina, Stictocephala inermis and Enchenopa 

 binotata. The species most injurious to stems belong to the genera 

 Ceresa and Stictocephala. 



Inasmuch as the nymphs of the most injurious species prefer to 

 feed on the more succulent weeds and grasses in the orchard, the 

 clean culture of badly infested orchards and the getting rid of 

 near-by weed patches in the early summer, will usually be all the 

 control measures necessary. Frequently in case of very severe in- 

 festations the careful pruning of the worst -infested twigs after egg 

 deposition is a desirable practice.
