20 SCALE INSECTS. 



Present Distribution. 



The presence of this pest in the United States was dis- 

 covered in 1870 in the San Jose valley, California. In 1873 

 it had become a serious menace to fruit raising in this part 

 of California. 



In 1886 or 1887 two New Jersey nurseries, desirous of 

 securing a curculio-proof plum, introduced from San Jos6, 

 Cal., the Kelsey plum. These trees were infested, failed to 

 thrive, and died from the attacks, but left the living scales 

 to commit depredations then unthought of. Directly or in- 

 directly from these shipments can be traced the present 

 status of this i^est in the East. It now exists in 25 states 

 and 2 territories in the union. The geographical distribu- 

 tion can be more readily understood from the following:
