 COCCIDJE given as affecting different plant genera is on the lines of 

 Green's very useful list published in the "Annals of Applied Biology" 

 1919. The appendix gives a list of species collected hi the Jaffa 

 District and Jerusalem during a short visit to Palestine at the end 

 of last year. 



I am much indebted to Mr. Laing, of the British Museum (Natural 

 History), for very kindly identifying many species for me and for 

 checking many doubtful identifications of my own. My thanks are 

 also due to Mr. E. E. Green and Mr. Willcocks (Sultanic Agricultural 

 Society of Egypt) who have been good enough to give me many 

 specimens.
