THE AUSTRALIAN BUG IN SOUTH AFRICA. 
♦ 
STB 
Iceryapurchasi (female), much magnified; group, magnified S. African; 
group on twig and leaf, rather less than life-size N. American. 
Of the various kinds of insect attacks which are 
hurtful to trees and shrubs in the South of Africa, 
probably those of the soft, cushiony, white, ribbed scale- 
insect, commonly known as the Australian Bug (the 
Cottony Cushion-Scale of North America), may be con¬ 
sidered as one of the most destructive, although this 
insect does not appear to be one of the native pests of 
the country, and little more than fourteen years have 
elapsed since it was first observed in the Colony.
