336 REPORT OF NEW JERSEY STATE MUSEUM. 



S. Candida Fabr. Throughout the State, late May to August, locally 

 common. The larva is the "round-headed apple borer," which some- 

 times does great injury in apple orchards, though it is even more 

 destructive in quince, and breeds also in "Crataegus" and "Amelan- 

 chier." The larva can be cut out when first noticed or reached with 

 a soft wire in the later stages; but the best practice is to protect 

 the base of the tree with some mechanical covering that will prevent 

 the parent beetle from laying eggs or the young from getting into 

 the trunk. Wire netting, paper, and other coverings serve the first 

 purpose; whitewash, cement, soap mixtures and similar compounds 

 the second.
