INTRODUCTION 
This catalogue is a supplement to Fascicle I, Membracidae, of the 
General Catalogue of the Hemiptera, which was published by Smith Col- 
lege in 1927 under the authorship of the late Dr. W. D. Funkhouser. Fol- 
lowing Dr. Metcalf’s arrangement, the Membracoidea are considered as a 
superfamily and include the families Membracidae, Aetalionidae, Bitur- 
ritiidae, and Nicomiidae. 
The genera were arranged some years ago by Dr. Metcalf in what he 
considered as nearly a phylogenetic order as knowledge would permit at 
the time. The species are arranged under the genera in alphabetic se- 
quence. In Dr. Funkhouser’s catalogue the genera and their species were 
arranged in alphabetic order within the subfamilies and tribes. 
This supplement contains in general only the literature references prior 
to 1927 which were not included in Dr. Funkhouser’s catalogue, and all 
available references from 1927 through 1955. Exceptions have been made 
when the dates, page numbers, or illustrations differed from those in the 
earlier book. In these cases the complete references have been repeated. 
Misspellings have been indicated, and the synonymy as given by various 
authors has been included. Doubtful genera and species have been in- 
cluded to call them to the attention of subsequent revisers. 
This work was virtually complete at the time of Dr. Metcalf’s death on 
January 5, 1956. The work has been completed by the junior author who 
was closely associated with the project for many years. The advice and 
counsel of Dr. David A. Young and Dr. Clyde F. Smith, North Carolina 
State University at Raleigh, and Dr. W. H. Anderson, Insect Identifica- 
tion and Parasite Introduction Laboratories, U. S. Department of Agri- 
culture, Beltsville, Maryland, on the completion of the present supplement 
is gratefully acknowledged. 
A catalogue of animals should serve practically all fields of biology. It 
should be, therefore, as complete a listing of all the records of families, 
subfamilies, tribes, genera, species, and varieties as it is possible for the 
author to assemble. The nature of the reference is of the greatest impor- 
tance. A student of zoogeography should be able to find a complete list of 
the regions inhabited by the various species. The student of ecology 
should be able to find references to all that is known about the life his- 
tory, food plants, and other pertinent data. The student of economic 
entomology should be able to check the histories of those species that are 
suspected of being injurious to plants. The plant disease specialist should 
be able to check the current nomenclature of the species which are disease 
vectors or suspected of being disease vectors. Those research workers 
studying morphology, physiology, or genetics should be able to trace the
