CICADELLINAE: PART 2. NEW WORLD CICADELLINI 709 
over the pronotum and diagonally through clavus at its base, continuing on 
corium to base of second apical cell; black costal margin of forewing bordered 
by a narrow yellowish green stripe in its basal portion, the stripe supplanted 
posteriorly by a broader translucent costal border extending almost to base of 
outer apical cell; face yellow with a black narrowly Y-shaped marking on cly- 
peus and clypellus and a black subantennal area on each gena; thoracic 
pleura and venter mostly black; legs stramineous except black apices of an- 
terior femora and black apical tarsomeres on all three pairs. Two of the fe- 
males have brown markings instead of black on the dorsum. 
Holotype and two additional males and five females, Macchu Picchu, Peru, 
November 25, 1967 (D. M. DeLong) (DeLong collection, OSU). 
The markings of S. picchitula, n. sp. are somewhat similar to those of S. 
taeniatifrons (Schmidt). The form of the styles and connective, and the abrupt- 
ly narrowed male plates are distinctive for picchitula.

FicuRE 575, PAGE 708 
Length of male 6.6-6.7 mm, of female 7.0 mm. Head moderately produced, 
anterior margin very broadly rounded in dorsal view, median length of crown 
varying from six-tenths to almost seven-tenths interocular width and ap- 
proximately four-tenths transocular width, crown with a transverse concavity 
before ocelli, clypeus slightly flattened medially, transclypeal suture obsolete 
at middle. Pronotum with width greater than transocular width of head, 
posterior margin slightly concave. Male pygofer well produced for genus, with 
apex narrowed to a pointed process which extends mesally but does not reach 
the median line, pygofer with a number of macrosetae on apical half and also 
parallel to dorsal and posteroventral margins; plates not extending posteriorly 
as far as pygofer apex; style not extending posteriorly nearly as far as apex of 
connective; connective with stem much longer than arms; aedeagus with a 
pair of short lobate processes arising ventrally on shaft before its midlength 
(these serve to guide the paraphyses parallel to the shaft); paraphyses as in S. 
occatoria (Say) (fig. 589h). Female abdominal sternum VII with posterior 
margin slightly produced medially in a short, rounded lobe. 
Color of head, broad anterior marginal border of pronotum and all of 
scutellum yellow, with a pair of broad longitudinal black stripes on crown, 
continuing posteriorly as a pair of dull brown stripes over pronotum almost to 
its posterior margin; forewing green with a longitudinal dull brown stripe in 
clavus, crossing claval suture and extending into apex of brachial cell apically, 
costal margin bordered with dull yellow to orange, narrowly so in basal half, 
more broadly so in apical half, some specimens with a narrow longitudinal 
dull brown vitta in corium; face, thoracic pleura and venter of abdomen pale 
yellow except two narrow brown lines on face, extensions of black coronal 
stripes, which converge ventrally, and except for black apices of first and 
second tarsi. 
Holotype male and twelve additional specimens of both sexes, ‘‘Sinchono”’, 
Peru some (not holotype) collected in July, 1944 (DeLong collection OSU).
