In the foregoing series I have omitted da genus ST AREA Targioni, 
not being able to make out exactly its distinction from Lecanium ; also the 
genus Planchonia, because, as stated in my paper of 1881 (Trans., vol. xiv., 
p. 223), it has the anal tubercles of Coccide in all stages. In the case of 
. many of the genera given above, as for instance Pollinia and Asterolecanium, 
or Lecanopsis and Aclerda, I do not know whether the. distinctions given by 
authors are sufficient: but I have not seen all these insects.
