The names in Italics indicate that the Agamic Generation only has hitherto been found in Epping Forest. Sfe p. 138 of text. 



With the exception of substituting Dryophanta folii (Linn) for D. scutellaris (Htg.), Andiicus trilineatus (Htg.) for A. noduli (Htg.), 

 for T. crustalis (Htg.), Mr. Cameron has, in the case of each gall, added in Italics the specific name used by Dr 



md Trigonaspis megaptera (Htg.) 

 . Adler.
