CHARACTERS OF THE FAMILY TROPIDUCHIDAE 
The Family Tropiduchidae is one of the smaller families of the Ful¬ 
goroidea. The present catalogue contains 106 genera and 280 species. 
Approximately one half of the known genera include but a single species. 
The members of this family have a superficial resemblance to the mem¬ 
bers of the family Dictyopharidae. The following generalized characters 
contribute to this superficial resemblance: head narrow, usually distinctly 
produced, the cephalic process usually short, triangularly or obtusely 
produced, sometimes elongate slender; pronotum short, tricarinate; 
mesonotum large, tricarinate; tegmina and wings typically transparent, 
the former commonly with a basal area with few or no crossveins save in 
the costal cell and an apical membrane with numerous crossveins most 
frequently arranged in one or two definite subapical lines. The family 
Tropiduchidae belongs to a different section of the superfamily Fulgoroidea 
and has the second hind tarsus small with a distinct spine on each side, 
not large with a crown of small spines at the apex as in the Dictyopharidae. 
Head narrower than the pronotum, frequently produced. The crown 
usually flat, with lateral margins and median line carinate; in the Tribe 
Peggiogini the head is produced into a long cylindric process. The frons
