INDEX OF PLANTS AND THE COCCIDID^E ATTACK- 



ING THEM. 



THIS list is of course only approximate,, as insects may at any 

 time be found on other trees than those given. 



Icerya Purchasi is omnivorous,, and it has not been thought 

 necessary to repeat it here against every plant in the list ; but 

 it has been set against some. 



The adult female of Coslostoma z&landicum may also be 

 found wandering over numbers of native trees in forests. 



In hothouses and greenhouses all sorts of plants are liable 

 to attack.
