CICADELLINAE: PART 2. NEW WORLD CICADELLINI 369 
54. SOOSIULUS, New ceENus 
Figures 297-322 
Type-species: Poeciloscarta fabricii Metcalf. 
Length of male 5.8-9.4 mm, of female 6.0-8.6 mm. 
Head well produced, median length of crown from slightly more than four- 
tenths to slightly less than nine-tenths interocular width and from ap- 
proximately three-tenths to slightly more than one-half transocular width, an- 
terior margin somewhat narrowly rounded in dorsal view, without a carina at 
transition from crown to face, ocelli located on or slightly before a line be- 
tween anterior eye angles, and each equidistant or nearly so from adjacent an- 
terior eye angle and median line of crown, with area between ocelli flattened 
or slightly concave, without a median fovea and without sculpturing or setae, 
lateral clypeal sutures extending onto crown and attaining ocelli; antennal 
ledges not protuberant, in lateral view with anterior margins rectilinear and 
oblique; clypeus convex, muscle impressions distinct or not, face without 
pubescence, transclypeal suture interrupted medially, clypellus with profile 
continuing contour of clypeus. 
Thorax with pronotal width variable compared to transocular width of 
head, lateral margins convergent anteriorly, dorsopleural carinae complete, 
posterior margin concave, disk without sculpturing or pubescence; scutellum 
_ without sculpturing. Forewing with membrane present, variable in extent 
interspecifically, veins indistinct, not elevated, with four apical cells, the base 
of the fourth more proximal than base of third, without an anteapical plexus 
of veins, texture at least partly coriaceous, without sculpturing; forewings of 
female in rest position exceeding apex of ovipositor. Hindleg with femoral 
setal formula 2:1:1, length of first tarsomere greater than combined length of 
second and third, with two parallel longitudinal rows of very small setae on 
plantar surface. 
Male genitalia: Pygofer moderately produced, posterior margin convex, 
with fairly numerous macrosetae usually extending in a broad diagonal group 
from middle of disk posterodorsally to dorsoapical margin, occasionally with a 
few interspersed microsetae, without processes. Plates slender, triangular, not 
extending posteriorly as far as pygofer apex, with few uniseriate macrosetae. 
Style extending posteriorly to a varying degree with relation to apex of con- 
nective, usually without preapical lobe. Connective extremely variable inter- 
specifically: from a simple transverse bar or a short T-shaped structure to a 
very elongate broad structure of various forms. Aedeagus not very elongate, 
symmetrical or not (variable interspecifically), with or without processes 
which may be unpaired or paired and anteapical or apical, the variation being 
interspecific. Paraphyses present and usually paired and symmetrical 
(exception: S. fulgidus, n. sp., in which they are reduced to a longitudinal bar- 
like sclerite at apex of connective). 
Female abdominal sternum VII with apical margin quite variable inter- 
_ specifically. Dorsal wall of genital chamber sclerotized or not. Ovipositor with 
_ second valvula broad beyond basal curvature, and with quadrate primary 
_ teeth, each bearing minute secondaries, apex convex, apicoventral margin
