ICERYA sp. 

Classification :—Order, HEMIPTERA. Family, Coccide. 
Tree attacked :—Casuarina equisettfolia. 
An examination of the pests at present known attacking 
the Casuarina in Madras would not be complete without a short 
mention of another insect discovered on trees in Waltair and 
Chatrapur. This is a member of the family Coccide, which 
contains so many pests to trees and plants. The insect is 
white, and in its older stages has a mass of white fluffy 
substance on its dorsal posterior surface, rendering it fairly 
conspicuous upon the branches upon which it lives by sucking 
out the sap.
