STINK BUGS. 



A number of these so-called stink bugs are commonly found at- 

 tacking the tomato vines. They are robust shield-shaped insects 



with sucking mouth parts, 

 and are usually very incon- 

 spicuously colored. Nezara 

 viridula, Arvelins alhopunc- 

 tatus and Euscliistiis hifihu- 

 h(s are the commonest of 

 these. 



While always to be found 

 they are never numerous 

 enough to cause serious dam- 

 age, and control measures are 

 not needed.
