INTRODUCTION 
The present catalogue of the Family Acanaloniidae forms Part 14 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 1923. 
CHARACTERS OF THE FAMILY ACANALONIIDAE 
The Family Acanaloniidae is one of the smaller families of the Ful¬ 
goroidea. The present catalogue contains 13 genera and 81 species. 
This family is frequently confused with the Flatidae because of the 
large tegmina and with the Issidae on the basis of various other charac¬ 
ters. The general characters of the family may be briefly summarized 
as follows: Head, including the compound eyes, usually slightly narrower 
than the pronotum or mesonotum. Vertex sometimes short and broad 
with anterior and posterior margins nearly parallel, sometimes triangular 
in outline, sometimes the frons and vertex are conically produced. Vertex 
not separated from frons by a distinct carina. Frons well developed with 
lateral carinae strongly elevated, sometimes with median and inter¬ 
mediate carinae, frequently as broad as long but in the species with 
conically produced heads the frons elongate, sometimes several times 
as long as broad. Clypeus much narrower than frons, elongate, triangular, 
not carinate laterally. Antennae short, basal segment collarlike, second 
segment usually subglobular, flagellum elongate. Ocelli laterad of the 
marginal carinae of the frons. Pronotum short and broad, anterior and 
posterior margins nearly parallel; lateral areas strongly developed. 
Mesonotum usually longer than broad, ecarinate. Tegmina large, coria* 
ceous, steeply tectiformed; apical margin broadly rounded, sometimes 
nearly straight and frequently oblique with the claval angle somewhat 
produced. Venation conspicuous with numerous supernumerary longi¬ 
tudinal veins and cross veins which make the venation closely reticulate 
over the corium and the clavus; basal cell large; costal area without cross 
veins; clavus not granulate, with two longitudinal veins united into a 
common stem which ends in the apex of the clavus; hind wings fairly 
large, venation simple, radius and medius usually united basally, anal 
area not reticulate. Trochanters of hind legs directed ventrad. Tibiae of 
hind legs without lateral spines before the apex; apex with a crown of 
spines. Second segment of hind tarsi small or very small with a spine on 
each side; the apex rounded or bluntly pointed. Ovipositors often re-
