crowns in autumn, but are not known to lay any 

 eggs until the following year. They pass the winter 

 as adults in the fields infested by them as larvee. It 

 feeds while a mature insect upon the tissues of the 

 plant." 



Remedies.— This insect is especially liable to in- 

 jure old strawberry fields, or those which are re- 

 planted to this fruit without some other crop inter-' 

 veiling. On account of the inability of the beetle to 

 fly, it is not likely to pass from one plantation to 

 another to deposit eggs, and the isolation of new 

 plantations from old ones is consequently to be de- 

 sired. If the plants for the new field must be taken 

 from an infested patch, they should be dug up as 

 early as possible to guard against transporting eggs 

 or larvaa with them. It is probable that spraying 

 the fields with the arsenites late in summer will lead 

 to the poisoning of many of the beetles, and that 

 burning the fields, after picking, will prove benefi- 

 cial. In case infested patches are to be plowed 

 under, this should be done late in June or early in 

 July, to destroy the half-grown larvae then present 

 in the crowns.
