{Note. The names in the foregoing list have, in most cases, been entered in the 

 exact form in which they have been recorded by the various observers. Consequently, 

 the same species may sometimes appear under different aliases: e.g. Pseudococcus 

 adonidum and longispinus ; Lecanium persicae, coryli and corni ; etc. I have left them 

 as they are, partly because the synonymy is not yet universally accepted and, also, 

 for the convenience of observers who would recognise the species more readily by the 

 names to which they are accustomed.)
