CICADELLINAE: PART 2. NEW WORLD CICADELLINI 445 
processes (except in deanna). Plates slender, triangular, usually extending 
posteriorly as far as or farther than pygofer apex, with uniseriate macrosetae, 
with microsetae variously distributed. Style extending posteriorly as far as, or 
farther than apex of connective, without preapical lobe, apex variable inter- 
specifically. Connective Y- or V-shaped with arms widely divergent. Aedeagus 
symmetrical, without processes (exception: 7. peragilis (Melichar)), in most 
species with shaft slightly decurved in lateral view. Paraphyses present or ab- 
sent, symmetrical when present and usually biramous. 
Female abdominal sternum VII variable interspecifically, but with posterior 
margin produced posteriorly to some extent in all species where female is 
known. Second valvula of ovipositor broadened and with dorsal margin bear- 
ing primary teeth through most of its length, most of the primaries slanted 
and bearing secondaries, except at basal portion of toothed portion where, in 
some species, the teeth are triangular and without secondaries, apex varying 
interspecifically, either acutangular or bluntly rounded; anteapical denticles 
present at least dorsally. Pygofer angular or angulate posterodorsally in lateral 
view, chaetotaxy varying interspecifically. 
Specimens belonging to the new genus Juliaca have been seen from Mexico 
to Bolivia, Venezuela, and southern Brazil. Juliaca and Mesogonia Melichar are 
closely related genera, and form an impressive part of the leafhopper fauna of 
the Neotropical Region even at this early stage in our knowledge. 7uliaca 
species differ from most species of Mesogonia in lacking a carina slightly 
behind the anterior margin of the head in dorsal view, and in that the lateral 
clypeal sutures extend over the anterior margin onto the crown in all species 
(seldom so in Mesogonia). The male plates of species of Juliaca usually extend 
posteriorly as far as or farther than the pygofer apex; they usually do not ex- 
tend as far posteriorly as the pygofer apex in Mesogonia. The styles of the 
males of Mesogonia species often extend much farther posteriorly than the apex 
of the connective; only slightly more posteriorly in Juliaca. Juliaca is also close 
to the new genera Fusigonalia and Geitogonalia in the discussions of which 
distinguishing characters are treated.
