CICADELLINAE: PART 2. NEW WORLD CICADELLINI 393 
Male pygofer unusually slender for the genus, with group of very minute 
microsetae near basiventral margin; plates not extending nearly as far 
posteriorly as pygofer apex, each with a few uniseriate macrosetae; style ex- 
tending posteriorly beyond apex of connective; connective elongate semi-oval 
in form, with a median full-length keel; aedeagus symmetrical with shaft slen- 
der and elongate for the genus, curved gradually downward, with a pair of 
short ventroapical processes extending parallel to long axis of apical portion of 
shaft; paraphyses broadly stalked with a lateral lobe before base of each 
ramus, rami slender, broadest in apical half, thence tapering strongly to acute 
apices. Female unknown. 
Crown, pronotum, and scutellum marked as S. sermunculus (Melichar) (fig. 
297a); forewing with an angular black spot bordering each humeral margin, 
connected very narrowly with transcommissural hastate claval black area 
which extends almost to apex, a second equally broad longitudinal stripe aris- 
ing in basal third of corium, extending almost to base of outer apical cell, 
costal margin and membrane, black. 
Holotype male, San Antonio, Loreto Province, Peru, August 23, 1965 (J. C. 
Hitchcock, Jr.) and one male topotype with same data except date which is 
August 20, 1965 (USNM). One male, Fonteb6a, Amazonas, Brazil (RMS). 
S. lunatus, n. sp., appears to be closely related to S. sermunculus (Melichar) 
from which it is indistinguishable externally. I have not been able to dis- 
tinguish females of this species from sermunculus. The males may be separated 
by the paraphyses which have a longer, broader stalk than in sermunculus and 
by the aedeagus which is longer and more regularly curved than in 
sermunculus. The apical aedeagal processes, in /unatus, are not directed at an 
angle to the long axis of the aedeagal shaft. 
Soosiulus fucatus, NEW SPECIES 
FIGURE 316, PAGE 392 
Length of male 6.4 mm. Head with median length of crown seven-tenths 
interocular width and slightly more than four-tenths transocular width, ocelli 
located slightly before a line between anterior eye angles, each slightly closer 
to adjacent anterior eye angle than to median line; clypeus with muscle im- 
pressions distinct. Thorax with pronotal width approximately equal to trans- 
ocular width of head; forewing with membrane including inner apical cell and 
most of remaining apical cells. Male pygofer without microsetae; plates not 
extending nearly as far posteriorly as pygofer apex, each with very few uni- 
seriate macrosetae; style extending posteriorly as far as apex of connective; 
connective subquadrate, slightly narrowed in basal half, without a keel; 
aedeagus symmetrical, almost straight, gradually expanded in apical half, 
without processes, gonopore subapical and ventral; paraphyses without a 
stalk, with a transverse basal connection, each ramus consisting of a ventral 
short slender acute process and a dorsal much longer, slender, tapered portion 
which is decurved apically. Female unknown. 
Crown with pair of anteapical marginal spots and a pair of basal large 
quadrate marginal spots extending forward as far as ocelli and from inner eye
