ated literature citations in his catalogues would have met with his ap¬ 
proval. 
Under the abbreviated system used here, and to be used for subsequent 
portions of the Cercopoidea catalogue, the literature references are cited 
by author, year, and key letter, e.g. Fabricius 1802a. The full reference can 
be obtained by consulting the Bibliography of the Cercopoidea in which 
authors are arranged alphabetically and their works chronologically under 
the author’s name. This method of citation eliminates the necessity for a 
complete literature citation in the catalogue proper. 
The Family Aphrophoridae consists of 151 genera and 820 species. Four 
invalid genera are included. This family may be characterized as follows: 
Eyes with horizontal diameter greater than vertical diameter; pronotum 
with anterior margin strongly convex or subangulate, anterolateral mar¬ 
gins usually short; scutellum flat, not spinous, shorter than pronotum; 
fore wing with clavus acute or obliquely truncate at apex. 
The following classification has been adopted for this family:

Twenty-five of the species in the present catalogue have a distribution 
covering two or more zoogeographic regions. The localities for four species 
are unknown. The other species are recorded as follows: 297 from the 
Palearctic Region, 103 from the Ethiopian Region, 100 from the Malaysian 
Region, 89 from the Austromalayan Region, 68 from the Oriental Region, 
43 from the Neotropical Region, 35 from the Caribbean Region, 20 from 
the Oceanic Region, 19 from the Nearctic Region, 16 from the Australian 
Region, and one from the Maorian Region. 
The known geographic distribution of each species is indicated by super¬ 
script figures at the end of the lines, which correspond to geographic re¬ 
gions designated by the same superscript figures. In general the distribu¬ 
tion is as given by the author of the reference, using the country as the 
smallest unit except in the larger countries where states and provinces are
