REMARKS. 



Found in Ceylon on the under surface of the leaves of Rhododen- 

 dron arboreum. The insects are hidden beneath the densely felted 

 hairs of the under surface of the leaves and can be detected only by 

 the small yellow discolored spots on the upper surface. Mr. Green 

 states that a very large proportion are destroyed by parasites.
