CICADELLINAE: PART 2. NEW WORLD CICADELLINI 397 
Soosiulus mirus, NEW SPECIES 
FicuRE 320, PAGE 396 
Length of male 7.0 mm. Head with median length of crown seven-tenths 
interocular width and slightly less than one-half transocular width, ocelli 
located before a line between anterior eye angles, each approximately equi- 
distant from adjacent anterior eye angle and median line of crown, clypeus 
with muscle impressions distinct. Thorax with pronotal width approximately 
equal to transocular width of head; forewing with membrane including inner 
apical cell and apical portions of remaining apical cells. Male pygofer with 
few very minute microsetae near basiventral margin; plates not extending 
nearly as far posteriorly as pygofer apex, each with few uniseriate macro- 
setae; style extending posteriorly to a point less than one-half length of con- 
nective; connective elongate, Y-shaped with stem longer than arms, slightly 
narrowed in basal third, slightly expanded in apical half and gradually 
narrowed to truncate apex, with an apical keel; aedeagus symmetrical, with 
an unpaired retrorse ventral process diverging from shaft near base of latter 
and abruptly narrowed and acute apically; paraphyses very short-stalked, 
each of rami slender and gradually tapered in dorsal view, in lateral view each 
abruptly narrowed in apical third and obliquely truncate at apex. 
Head and pronotum with black markings much as in S. fabric: (Metcalf) 
(fig. 300a), except that posterior marking of crown is interrupted medially; 
scutellum black in basal half; forewings each with a diagonal black stripe in 
clavus including most of humeral and more than one-half of commissural 
margins, corium with a black stripe arising at wing base, extending parallel to 
brachial cell to claval apex thence posterolaterally to bases of apical cells, 
costal margin narrowly, and membrane, black. 
Holotype male, ‘Peru’? (OSU). 
S. mirus, n. sp., is distinct from other species of the genus except S. 
flammidulus (Jacobi) in its unpaired aedeagal process that arises basiventrally. 
It differs from flammidulus in the markings of the anterior dorsum, the shape of 
the paraphyses, and in that its aedeagal process is retrorse. 
Soosiulus facis, NEW SPECIES 
FIGURE 321; PAGE 398 
Length of female 7.0-7.5 mm. Head with median length of crown approx- 
imately six-tenths interocular width and from one-third to slightly less than 
four-tenths transocular width, ocelli located before a line between anterior eye 
angles, each slightly closer to median line of crown than to adjacent anterior 
eye angle, clypeus with muscle impressions distinct. Thorax with pronotal 
width approximately equal to transocular width of head; forewing with mem- 
brane including inner apical cell and apical portions of remaining apical cells. 
Male unknown. Female abdominal sternum VII with posterior margin 
gradually and moderately produced, concavely and shallowly emarginate at 
apex.
