CICADELLINAE: PART 2. NEW WORLD CICADELLINI 387 
slightly less than four-tenths to slightly less than one-half transocular width, 
ocelli located on a line between anterior eye angles, each slightly closer to ad- 
jJacent eye angle than to median line of crown, clypeus with muscle im- 
pressions not very distinct. Forewing with membrane including inner apical 
cell and apical portions of remaining apical cells. Other external structural 
characters as in §S. interpolis, n. sp. (p. 374). Male pygofer with extremely 
minute microsetae near ventral margin; plates not extending posteriorly 
nearly as far as pygofer apex, each with approximately six uniseriate macro- 
setae; style extending posteriorly as far as apex of connective; connective 
elongate semi-oval in form with a median keel throughout its length; aedeagus 
symmetrical, in lateral view with shaft broad, its ventral margin very strongly 
concave, rounded dorsoapically, with an apicoventral process extending ven- 
trally and obliquely truncate at apex; paraphyses with a long very slender 
stalk, in lateral view each ramus slender, biundulate, acute apically, the 
apices directed dorsally, without a convexity at apex of stalk or at bases of 
rami. Female unknown. 
Crown yellow tinged with orange, with a pair of large marginal black spots 
behind apex, and an irregularly margined black spot at base extending an- 
teriorly before ocelli; pronotum black with a transverse yellow band which is 
constricted at middle; scutellum black except orange apex; forewings dull 
orange, with a small lenticular transcommissural claval spot, claval suture and 
costal margin narrowly, and membrane, black, anteapical portion of wing suf- 
fused with dark red. 
Holotype male, Maroni River, French Guiana and two additional males, St. 
Jean, Maroni River, French Guiana (NCS). Holotype on indefinite loan to 
USNM. 
S. maroniensis, n. sp., is apparently related to S. decoris, n. sp. (above), but 
may be readily separated from the latter by its broader aedeagal shaft in 
lateral view, its broader apicoventral aedeagal process, and the biundulate 
rami of its paraphyses in lateral view. S. maroniensis can be recognized ex- 
ternally because of its large size, the large amount of black on the anterior 
dorsum and the scarcity of black markings on the forewings (see description 
above).

FIGURE ott PAGE 388 
Length of male 7.0 mm, of female 7.0-7.3 mm. Head with median length of 
crown from slightly more than one-half to slightly more than six-tenths inter- 
ocular width and from slightly more than one-third to more than four-tenths 
transocular width, ocelli located slightly before a line between anterior eye 
angles, slightly variable as to relative distance from anterior eye angle and 
median line, clypeus with muscle impressions not very 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 a number of extremely minute microsetae near
