A Monograph Of The British Phytophagous Hymenoptera Vol 4

Excerpt from A Monograph of the British Phytophagous Hymenoptera, Vol. 4: Cynipid and Appendix The Appendix brings up our information to date, more particularly as regards the nomenclature and biology of the groups. As will be seen, considerable alteration has been made in the definitions of the genera, their number, as compared with what Thomson and myself have adopted, being greatly increased. The only remark I make on this subject 18 that if exotic Species are to be treated according to the same method a large number of genera or sub-genera will have to be created.
