INTRODUCTION 
The present catalogue of the Family Lophopidae forms Part 17 of 
Fascicle IV of the General Catalogue of the Homoptera of the World 
which is devoted to the Superfamily Fulgoroidea. 
CLASSIFICATION ADOPTED 
The classification adopted in the present catalogue is a modification of 
the one proposed by Melichar in 1915. 
CHARACTERS OF THE FAMILY LOPHOPIDAE 
The family Lophopidae is one of the smaller families of the Fulgoroidea. 
The present catalogue contains 41 genera and 1 13 species. 
Head, including the compound eyes, usually decidedly narrower than 
the pronotum. Vertex frequently much narrower than its length; sometimes 
protuberant; lateral margins strongly elevated. Frons elongate, sometimes 
distinctly angulate below the compound eyes, the lateral margins carinate, 
sometimes with intermediate carinae or a median carina, sometimes -with 
both. Postclypeus with lateral margins carinate and a distinct median 
carina. Pronotum short and broad, tricarinate. Mesonotum short and 
broad, tricarinate; tegulae usually large. Tegmina coriaceous with venation 
conspicuous; elongate; costal and commissural margins nearly parallel, 
apical margin broadly rounded, sometimes nearly truncate, with super- 
numerary longitudinal and crossveins, costal cell with numerous cross- 
veins; claval veins united before the apex. Fore and middle tibiae generally 
compressed and expanded. Muir points out that the apical spines of the 
hind tibiae are arranged as a simple apical row, or with some of the spines 
joined together to form a plate, or spines irregular, not forming an apical 
row. Second segment of hind tarsi small, without apical spines. 
In the male genitalia which I have studied the pygofer is usually short. 
The genital styles are large. The aedeagus is usually robust with a com- 
plicated set of apical spines. The tenth segment is elongate with the telson 
well developed. The female genitalia are incomplete. 
HISTORICAL RESUME 
Melichar 1915b gives keys to and descriptions of the genera that were 
known at that time and a detailed catalogue of the known genera and 
species. 
GEOGRAPHIC DISTRIBUTION 
All the species in this family are confined to the tropical or warm tem- 
perate regions of the world. Five of the species in the present catalogue
