CICADELLINAE: PART 2. NEW WORLD CICADELLINI 425 
muscle impressions not very distinct. Thorax with pronotal width greater than 
transocular width of head; scutellum not striate behind transverse sulcus; hind- 
leg with length of first tarsomere approximately equal to combined length of two 
more distal tarsomeres. Other external characters as in generic description. Male 
with plates not extending nearly as far posteriorly as pygofer apex, aedeagal shaft 
broadened in apical half in lateral view and with an apical ventral unpaired 
retrorse acute process; other male genital characters an in generic description. 
Female with second valvula of ovipositor with quadrate primary teeth extending 
almost to apex, apicoventral margin concave. 
Color amber, lateral margins of crown except at apex, lateral margins of 
pronotum, a longitudinal irregular vitta on forewing bordering basal half of 
claval suture, crossing claval suture at midlength of latter, extending 
posteriorly to basal portion of inner apical cell, a lateral branch to costal 
margin, and wing apices narrowly, black. Type with apical half of clavus and 
a poorly delimited spot in anteapical cells, pink. Face, thoracic pleura, and 
legs, yellow. 
Holotype male, Jurassal, Angra, Estado de Rio (Travassos and Lopes), Oc- 
tober, 1934 and one topotypic female, November, 1934 (L. Travassos) 
(USNM). 
P. angrana, n. sp., can be distinguished from all other species in the genus 
by its much smaller size, by its color pattern, and by the shape of the 
aedeagus in lateral view.

FIGURE 346, PAGE 426 
Length of male 12.0 mm, of female 12.0-12.4 mm. Head of male with me- 
dian length of crown almost one-half greater than interocular width and 
almost nine-tenths transocular width; of female with median length of crown 
from very slightly greater to one-fifth greater than interocular width and from 
seven-tenths to almost nine-tenths transocular width, ocelli each closer to me- 
dian line of crown than to adjacent anterior eye angle, disk of crown convex 
medially before ocelli, lateral clypeal sutures not attaining ocelli, antennal 
ledges not foveate; clypeus concave in lateral view, without a protuberance 
beneath apex of head, muscle impressions obscure in male, distinct in female. 
Thorax with pronotal width greater than transocular width of head; scutellum 
not (type) or only obscurely striate behind transverse sulcus; forewing with in- 
ner apical cell membranous; hindleg with length of first tarsomere greater 
than combined length of two more distal tarsomeres. Other external charac- 
ters as in generic description. Male with aedeagal shaft slender and of almost 
uniform width throughout length, with a short, straight, thornlike ventral 
process near midlength (of genital structures not illustrated, the plates, styles, 
and connective are most like P. infulata, n. sp.). Female with second valvulae 
of ovipositor with quadrate teeth extending almost to apex, apicoventral 
margin convex.
