CICADELLINAE : PART I. PROCONIINI 163 



ocelli; antennal ledges protuberant, each with a longitudinal fovea in 

 dorsal aspect, in lateral aspect with dorsal margins carinate, anterior 

 margins steeply declivous; clypeus slightly depressed medially, muscle 

 impressions distinct; transclypeal suture concealed; face thickly beset 

 with dense long pubescence beneath; entire clypellus at right angle to 

 contour of clypeus. 



Thorax with pronotal width less than transocular width of head, 

 lateral margins subparallel, surface rugose and punctate, pubescent, 

 posterior margin concave, with complete dorsopleural biundulate 

 carinae; posterior half of scutellum v/ith a dense area of erect pubes- 

 cense. Forewing hyaline, veins distinct, usually with a smoky area at 

 base of anteapical cells, and occasionally with additional smoky sub- 

 hyaline areas, venation as in Rhaphirrhinus (p. 157), wings of female at 

 rest extending farther posteriorly than apex of ovipositor. Hindwing 

 at rest extending posteriorly only to bases of apical cells of forewing, 

 with vein Ra-f 3 incomplete. Forelegs with tibiae expanded and flattened 

 apically. Hindlegs at rest with knees not attaining posterior proepimeral 

 margins; setal formula 2:0:0; first tarsomere shorter than combined 

 length of second and third. Abdomen in dorsal aspect short, broad, 

 slightly flattened in both sexes, its lateral areas visible in dorsal aspect 

 at sides of wings at rest. 



Male genitalia: Pygofer very slightly produced posteriorly, posterior 

 margin rounded or slightly concave, with dispersed microsetae on 

 posterior half, without processes; ninth tergum not separated from 

 sternum by a suture. Plates separate throughout their length, triangular 

 with apices broadly roimded, with nimierous dispersed microsetae. 

 Style extending as far posteriorly as apex of connective, wdth preapical 

 lobe, apex foot-shaped, with few serially-arranged lateral microsetae 

 behind preapical lobe. Connective Y-shaped with arms shorter than 

 stem which is not carinate. Aedeagus symmetrical, much as in Rhaphir- 

 rhinus, with a laterotergite on each side above dorsal apodeme, without 

 processes. Paraphyses reduced to a single small sclerite between con- 

 nective and base of aedeagus (not shown in illustrations). 



Female abdominal sternum VII narrow, posterior margin sinuate on 

 each side of median produced rounded lobe. 



In this genus the male genitalia and the venation of both pairs of 

 wings are similar to Rhaphirrhinus. Teletusa stands well apart from other 

 genera in this tribe in its very pubescent scutellum and lower portion 

 of the face, in the very short pygofer of the male, and in the broad, 

 flattened, short abdomen, 



I have been unable to find specific characters for the nominal species 

 provisionally considered here as a single species. Specimens have been 

 examined from Amazonas to Bolivia and to Paraguay and Argentina,
