BIBLIOGRAPHY OF 
already been adopted by several authors (Oman 1949a) with consequent 
great saving in space. 
The use of this system has made it necessary to prepare separate bibli¬ 
ographies for each of these fascicles, since the Bibliography of the Homoptera 
Auchenorhyncha lacked a number of references to pertinent literature, and 
also a great deal of important information has been published since that 
work was completed in 1942. 
The literature references appear in the bibliographies following the 
corresponding author, year, and letter entry. All entries are arranged 
alphabetically by authors and chronologically under each author’s name. 
Each reference is designated by the year in which it appeared with the 
first bearing the suffix “a” and other works in the same year being assigned 
the letters “b,” “c,” “d,” and so on. In order to avoid possible confusion 
by having different sequences of letter suffixes associated with the dates 
in the different bibliographies it was decided to retain the suffixes used in 
the Bibliography of the Homoptera Auchenorhyncha , even though in these 
subsequent works the sequence of letters in a given year is sometimes 
broken. The code designations for publications are thus consistent for the 
separate bibliographies. 
This Bibliography of the Cicadoidea is an indispensable adjunct to the 
parts of Fascicle VIII that will follow. Abbreviations in this publication 
follow in general those adopted by the U. S. Department of Agriculture.
