Introduction 
may be described briefly as follows: Subcosta and radius united to near the 
apical third, where subcosta curves toward the costal border and forms a 
distinct nodal cell which is usually crossed by several branches of subcosta. 
After the separation from subcosta, radius usually branches irregularly and 
is united to the first branch of media by one or more cross veins. In many 
species there is an irregular series of cross veins on the apical third, forming 
a transverse vein similar to the transverse vein found in the family 
Tropiduchidae, and for this reason there has been considerable confusion 
in placing certain genera and species in these two families. However, the 
two families may be separated readily by the character of the second seg- 
ment of the hind tarsi which is large in the members of the family Dicty- 
opharidae and small in the species in the family Tropiduchidae. Media 
and cubitus fork before the transverse vein in many species of Dictyo- 
pharidae and the apical area usually has numerous irregular cross veins. 
In the species with brachypterous tegmina the venation is very irregular 
and variable. 
The hind wings are large in most macropterous forms, with the venation 
somewhat irregular and with usually numerous cross veins in the apical 
area but not in the anal area. This character will aid in differentiating cer- 
tain members of this family from species of the family Fulgoridae, with 
which they might otherwise be confused. Hind wings are frequently absent 
in brachypterous forms. 
The male genitalia are complex. Muir (1930) says, “There is an inner 
penis and an outer periandrium, and the membrane connecting them can 
be protruded and inflated, and is complex, often bearing armatures.”
