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.
