INTRODUCTION 
The present catalogue of the Family Dictyopharidae forms Part 8 of 
Fascicle IV of the General Catalogue of the Hemiptera of the World, which 
is devoted to the Superfamily Fulgoroidea. 
CHARACTERS OF THE FAMILY DICTYOPHARIDAE 
The Family Dictyopharidae is one of the larger families of the Fulgo- 
roidea. The present catalogue contains 119 genera and 489 species. Most 
of the species are medium sized fulgoroids with strongly modified heads. 
The head is proportionately large, frequently with a distinct cephalic 
process v T hich may be conically or teretely produced. In other genera the 
head is not produced in front of the compound eyes, and the vertex rounds 
into the frons sometimes with and sometimes without a transverse carina 
separating the one from the other. The vertex is usually broader than the 
short diameter of the compound eyes; sometimes with, but more frequently 
without, a median carina. The frons is usually elongate, with strong median, 
lateral, and intermediate carinae; although any of these may be wanting. 
The compound eyes are usually semiglobose with the sinus wanting or in- 
conspicuous. The antennae are usually small and inconspicuous; the first 
segment collar-like; the second usually globose or obovate; the flagellum 
moderately elongate. The paired lateral ocelli are usually present and are 
situated on the lateral area of the head in front of the compound eyes, or 
sometimes below the eyes. 
The thorax is conspicuous, with the pronotum and mesonotum sometimes 
subequal in length and breadth. Frequently the pronotum is short, broad, 
and collar-like. Quite frequently it has median and intermediate carinae, 
with two conspicuous lateral carinae behind the compound eyes. The 
mesonotum is sometimes rhomboidal in outline, with the anterior margin 
triangularly produced. The tegulae are usually large, frequently carinate. 
In the subfamily Orgeriinae the tegulae are absent. The legs are usually 
slender and elongate; but in some genera the fore femora or tibiae or both 
( Phylloscelis Germ.) may be greatly expanded. The hind tibiae generally 
bear three or five stout spines. Second segment of hind tarsi large, with a 
row of small, stout spines at the apex. 
Tegmina macropterous or brachypterous. Rarely both long and short 
winged forms are found in the same genus ( Scolops Schaum, Phylloscelis 
Germ.). The members of the subfamily Orgeriinae are all brachypterous and 
lack the claval suture usually characteristic of homopterous tegmina. The 
venation of the macropterous tegmina is of a fairly constant pattern and
