margin convex, bearing teeth on dorsal margin throughout portion beyond 
basal curvature, the primaries very broad and bearing secondary teeth. 
Ferrariana, new genus, probably occurs from Costa Rica to Argentina and 
sduthern Brazil, although I have not yet seen specimens from Ecuador. 
Ferrariana appears to be related to Graphogonalia, new genus, but the venation 
of the forewings and the color pattern of the crown will serve to separate these 
two genera easily. Ferrariana is also close to Coronigonalia, new genus, but dif- 
fers in its lack of pygofer processes in the males, and in its broader second 
valvulae of the females. Species of Ferrariana have a marginal red or orange 
band on the crown, a feature shared with species in other genera (see discus- 
sion of Coronigonalia for details), including Szbovia pileata (Fowler), but the 
Fowler species has the second valvulae of the female with the toothed area re- 
stricted as in other Sibovia species, in contrast to the condition in Ferrariana. 
I am pleased to name this genus in honor of Pietro Modesto Ferrari, whose 
work (1882a) demonstrates clearly that he knew the taxonomic worth of the 
male genitalia of leafhoppers a half century before these structures came into 
general use by other systematists in Cicadellidae. 
Earlier in the course of the present work, I had not yet realized the identity 
of Tettigonia trivittata Signoret, of which I had studied only the female type 
(Walker’s pallipes in the British Museum). I returned a number of specimens 
to various museums with the manuscript name: Coronigonalia evincta Young, as 
a result.
