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

 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 

 the fruit and the leaves. It is 

 a large yellowish brown beetle, 

 with three dark spots on each

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