section it is surprising!}' destructive. On April 13, 1900, the writer 

 examined an orchard of 2,000 Robinson plums in that section that was 

 thoroughly infested with this scale. Scarcely a tree could be found 

 that was free from it, and most of them were encrusted from the 

 ground to the tips of the twigs. Branches that had been killed by 

 the scale the previous fall still retained their old leaves. 



At the above date the young had apparently been hatched for 

 several days. They covered the branches and the white filamentous 

 wax exuded b}^ the larvffi was profuse. No effort was made to save 

 the trees and they were dug up ; however, not before the scale had 

 spread to an adjoining peach orchard, which became badly infested.

(28) Pulvinaria acericola W. & R. 



On June 1, 1900, the writer examined two maple shade trees {Acer 

 daKycai'pum f) in Atlanta that were thoroughly infested with this species. 

 They were crowded on the branches, while the leaves were not so badly 

 infested. At the date named a considerable per cent of the females 

 had extruded their ovisacs, and, peculiar!}' enough, the majority of 

 them did not migrate to the leaves. This species also occurs abun- 

 dantly on Acer pennsylvanicum. in Atlanta.
