CICADELLINAE: PART 2. NEW WORLD CICADELLINI 389 
short-stalked, each of the rami long, slender, tapered, acute apically. Female 
abdominal sternum VII with posterior margin transverse or shallowly con- 
cave and with slight median convexity, with a midventral longitudinal 
elevated area extending basally through more than apical half. 
Markings of crown, pronotum, and scutellum as in S. interpolis, n. sp. (p. 
374), but lacking small spot on each side of pronotum near lateral margin; 
forewings each with an angular or linear spot on humeral margin, connected 
by a narrow black marking along commissural margin with a transcom- 
missural hastate or elongate-triangular claval black spot, claval suture narrow- 
ly, and membrane, black. 
Holotype male and one female, ‘‘Santarem”’, Brazil; two females and one 
specimen without abdomen, “Para’”’, Brazil (USNMY. One female, Villa 
Braga, Brazil (CM). One female, lower Amazon (RMS). 
S. hastatus, n. sp., may be distinguished from other species, except S. ruber, 
n. sp., by its paired dorsal aedeagal processes and from ruber by the asym- 
metry of these processes and by the broader ventroapical process than in ruber. 
The females differ from ruber females by the more nearly rectilinear or slight- 
ly concave posterior margin of sternum VII in hastatus.

FiGuRE 312, PAGE 388 
Length of male 7.0-7.6 mm, of female 6.7-7.2 mm. Head with median 
length of crown from six-tenths to seven-tenths interocular width and from 
one-third to almost one-half transocular width, ocelli located before a line be- 
tween anterior eye angles, each equidistant from adjacent anterior eye angle 
and median line of crown, 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 por- 
tions of remaining apical cells. Male with aedeagus symmetrical, shaft 
regularly curved posterodorsally in lateral view, with a pair of erect tapering 
acute anteapical processes and a very slender acute retrorse ventroapical 
process; other male genital characters as in §S. hastatus, n. sp. Female ab- 
dominal sternum VII with most of posterior margin regularly, broadly con- 
vex. 
Color of crown, pronotum, and scutellum as in S. interpolis, n. sp. (p. 374), 
except that there is no small spot on each side of pronotum near lateral 
margin and that pale area of scutellum is more extensive, occasionally oc- 
curring as a median sagittate pale marking; forewing with claval black mark- 
ings as in S. hastatus, n. sp., except that the transcommissural spot is not 
hastate in any of the specimens at hand; corium with a single black stripe of 
variable width, either narrow at base, extending posteriorly along and 
broadening almost to apex of claval suture, thence narrowing slightly and ex- 
tending to central anteapical portion of corium (type), or narrow throughout 
its length and extending as in specimens with the broader stripe, membrane 
black.
