THE EGYPTIAN ICERYA.

It will be remembered that in the double number of Insect Life for 

 January and February, 1890, p. 256 (Vol. II, Nos. 7 and 8), we mentioned 

 under the heading " An Egyptian Mealy Bug " the receipt from Mr. D. 

 Morris, of the Royal Kew Gardens, of a copy of a letter from Mr. R. W. 

 Blunfleld, of Alexandria, Egypt, giving an account of a scale insect 

 which during the past four years has infested the gardens of Alexandria, 

 killing all the trees and causing the greatest alarm. It was said to have 

 first appeared upon the Banyan tree, soon spreading with marvelous 

 rapidity to many other plants. The statement was made that " a breeze 

 sends the cottony pests down in showers in all directions." 



Specimens were referred by Mr. Morris to Mr. J. W. Douglas, who 

 in the Entomologists Monthly Magazine, second series, Vol. I, pp. 79-81 

 (March, 1890), described it as Crossotosoma n. g. cegyptiacum n. sp.
