This comprehensive work lists some 2500 species and 330 genera 

 from all parts of the world. It is more than a list of the species, 

 since it is a generic synopsis and contains keys for the separation of

 cuted and the copious three-column index, occupying ig quarto pages, 

 makes the contents most accessible. The work has been prepared by 

 one who has spent years of productive labor upon the group and has 

 probably seen more genera and species of gall midges than any one

 should therefore represent the latest and most advanced taxonomic 

 ideas. The following tabulation gives the author's arrangement in
