CICADELLINAE: PART 2. NEW WORLD CICADELLINI 149 
Female abdominal sternum VII with posterior margin varying inter- 
_ specifically. Ovipositor and pygofer as in Dilobopterus. 
Specimens belonging to the genus Lissoscarta have been studied from British 
_ Guiana, northeastern, central, and northwestern Brazil, from Peru, and 
Bolivia. Lissoscarta is closely related to Dilobopterus from which it may be dis- 
tinguished by its larger size, the consistently membranous forewing and the 
constriction at the base of the abdomen. 
The lectotype of Cicada vespiformis Fabricius is a female, and it was not dis- 
sected. The type-locality was South America. Most of the Fabricius species of 
Cicadellinae with such a type locality have proven to be from the Guianas, 
and since only one species in the genus has been found from the Guianas in 
the present study, I have assumed that this is vespiformis. 
The color markings of the anterior dorsum of all of the species are fairly 
similar, and the accompanying illustration of L. vespiformis (Fabricius) (fig. 
115a) and the color description of L. schlingeri, n. sp., will serve for all, except 
for some differences in the markings of the crown.
