PEAR AND QUINCE INSECTS 235 



have established itself in injurious numbers only in California, 

 although recorded also from several Eastern states. It has 

 attacked pear and prune trees principally in this country, 

 but the apple, plum, peach and currant are among its food- 

 plants. Specimens we saw on pear seedlings from France 

 were in little pits or depressions in the bark, and others state 

 they occur under the edges of rough bark or moss. Appar- 

 ently it spreads and breeds slowly, so it will doubtless never 

 be a serious menace to American orchards. The winter appli- 

 cations recommended for the San Jose scale will probably con- 

 trol it if thoroughly applied.
