INTRODUCTION 



This index contains the names of all genera, species, subspecies, 

 and varieties that are listed in Parts 1 through 17, Fascicle VI, 

 Cicadelloidea, of the General Catalogue of the Homoptera by the 

 late Z. P. Metcalf. The generic section lists the genus and its 

 author and includes the group names (without authors). Sub- 

 genera and their authors are listed in parentheses, following the 

 style established by Dr. Metcalf, although the present custom is 

 to place authors' names outside parentheses. The specific section 

 shows the name of the species, its author, and the generic name 

 under which it is treated in this series. The part in which each 

 taxon occurs in the catalogue is indicated by boldface type, and the 

 page number follows. The original generic combination can be 

 found easily since the references in the catalogues are given in 

 chronological order. There are cross references in the catalogues 

 for all known generic combinations and also for all misspellings 

 and emendations. 



Amyot's nonbinominal names are listed in the species section. 



Nomina nuda are listed in italics. 



No official rules were in effect during the time that much of 

 this catalogue was in preparation. Some names, therefore, are 

 listed with diacritic marks. Also, names formed from personal 

 names bearing the prefix ''Mc" have not been changed to "mac" 

 as recommended in the International Code of Zoological Nomen- 

 clature. 



Anton August Heinrich Lichtenstein's Catalogue musei Zoologici 

 ditissimi Hamburg, 1796, which had not been included in Dr. 

 Metcalf's card catalogues, was discovered in 1963. It was decided 

 not to add this work at this late date. It is considered by some 

 authorities to be merely a sales catalogue and probably would not 

 be accepted by the International Commission on Zoological Nomen- 

 clature as constituting publication even though Lichtenstein did 

 give binominal names to previous descriptions.
