section it is surprisingly 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 by the larvee 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. 
(22) Chionaspis ewonyms Comst. 
Found severely infesting a hedge of euonymus at Decatur, Ga. It 
became so injurious that the hedge was destroyed. 
(23) Chionaspis americana Johnson. 
This species is quite injurious to U//mus americana, used as shade trees 
in Atlanta, Augusta, and Americus, Ga., and undoubtedly occurs in 
many other cities of the State. 
(24) Chionaspis nysse Comst. 
Found in great abundance on Vyssa sylvatica in a forest near Powder 
Springs, Ga. The females were confined to the trunk and branches, 
while the males were principally upon the leaves. 
(25) Ischnaspis longirostris Sign. 
On Kentia belmoriana in a greenhouse at Atlanta, Ga. 
(26) Piorinia fiorinie Targ. 
Found in greenhouses at Thomasville and Augusta, Ga., on Camellia 
japonica and Cycas revoluta. 
(27) Pulvinaria immunerabilis Rath. 
Occurs sparsely on oak, elm, and sycamore at Atlanta, Austell, and 
Tifton, Ga. 
(28) Pulvinaria acericola W. & R. 
On June 1, 1900, the writer examined two maple shade trees (Acer 
dasycarpum ?) 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, peculiarly enough, the majority of 
them did not migrate to the leaves. This species also occurs abun- 
dantly on Acer pennsylvanicum in Atlanta. 
(29) Pulvinaria amygdali CAL 
This coecid occurs in injurious numbers on plums at Albany, Pine 
City, Marshallville, and Fort Valley, Ga. It also occurs on apples at 
Albany, Ga. 
(30) Pulvinaria maclure Kennicott in Fitch. 
Found on osage orange in Atlanta, Ga.
