posing them by turning up the soil, when large 

 numbers of them will be destroyed by poultry 

 and birds. The moles help a little, for we have 

 found both the larvae and the beetle in its stom- 

 ach. Fortunately, all the cockchafers prefer 

 grass land for their nidus, so that the depreda- 

 tions of the larvae are confined mostly to young 

 vineyards made on newly broken land. 



The spotted bug (Pelidnota

 enemy to the vine, destroying

 with three dark spots on each

About the size of this, but appearing as early 

 as May, is the golden bug, (Areoda lanigera^) 

 a very beautiful beetle of a bright lustrous

 this and the Pelidnota are like that of the
