CXCI—MEALY BUG AT ALEXANDRIA. 
In the Kew Bulletin for May 1890 an account is given of * a Mealy 
Bug, very destructive to cultivated plants,” which has recently made its 
appearance at Alexandria. This was described by Mr, J. W. Douglas 
as Crossotosoma egyptiacum. 
Mr. Riley, the United States entomologist, makes the following 
remarks upon the subject in the -January number of Insect Life, 
р. 184:— 
“ A study of Mr. Douglas’s description and figures has convinced me 
that this insect is an Zcerya, and that its spread is greatly to be feared 
judging from our experience with Z. Purchasi. Moreover, three addi- 
year: one occurring in Mexico on grapevines ; another in Key West, 
Florida, upon roses and other garden plants; and the third in the 
island of Montserrat, West Indies, upon the cocoa palm, the banana, 
and a species of Chrysophyllum.” 
A full account of Icerya Purchasi, Maskell, the Fluted Scale-insect, | 
was published in the Kew Bulletin for August 1889.
