CICADELLINAE: PART 2. NEW WORLD CICADELLINI 307 
The present identification of Tettigonia albostriata Signoret is based on a 
comparison of females with sketches of the type made by the writer in Vienna, 
and males associated with these females. 
Parathona gratiosa (Blanchard) rests on a comparison of specimens deter- 
mined by Signoret, in Vienna, with illustrations of the male genitalia 
published here. The interpretation agrees with Melichar-determined speci- 
mens in the museum in Budapest. I have identified Tettigonia drewseni Stal 
with gratiosa as a result of comparing specimens of gratiosa from northern 
Argentina with Stal’s original description. 
P. interstitialis (Signoret), as here interpreted, rests on a comparison of a 
specimen from the Carnegie Museum with the original illustration of this 
species. 
The writer has not seen a typical specimen of (P. lyncea (Fabricius)) = P. 
cayennensis (Gmelin). The holotypes of the synonymous Tettigonia cyanescens 
Walker and Cicada myopa Fabricius have been studied.
