CICADELLINAE: PART 2. NEW WORLD CICADELLINI 51 
I have examined the lectotype of Trichogonia ardentula Breddin. I have not seen 
type material of 7. areata Melichar. The lectotype of 7. boliviana Distant has been 
~ studied. 
No specimens of Tettzgonia costata Signoret eligible to be lectotype were found in 
the collections at Vienna, or in MHNP. Both museums had specimens from 
- Bolivia, those in Vienna with Signoret’s determination labels, but the original 
description gave ‘“‘La Guayra”’ [Venezuela] as the type locality. 
__ T have studied the lectotype of Tettigonia duplicaria Distant. The only specimen 
of Trichogonia intermedia Schmidt I have been able to identify is the lectotype, in 
Warsaw, hence this species has not been included in the key (below). I have ex- 
amined the lectotype of 7. isabellula Breddin.
