CICADELLINAE: PART 2. NEW WORLD CICADELLINI 33 
anteapical plexus on the forewings, and in the absence of macrosetae on the male 
plates, and differs from Ortega and Aguana in both of these characters. Neiva 
differs from Paracatua in the aedeagal shaft which is longer and lacks the pro- 
cesses present in Paracatua, and in the more extensive and numerous setae on the 
male pygofer. Amalfia Melichar (p. 1096) probably belongs in this complex of 
genera. 
The genitalia of the male lectotype of V. rufipes Melichar agree well with the il- 
lustration published here; the female characters, not illustrated, are much as in 
variolata (Melichar). The genitalia of Acharista variolata Melichar and the lec- 
totype of its synonym, A. maculata Melichar, also agree with the present 
illustrations.
