CICADELLINAE: PART 2. NEW WORLD CICADELLINI 479 
than one-half transocular width, crown with a slight transverse concavity 
before ocelli; pronotum and scutellum without rugae; forewing with bases of 
anteapical cells opposite claval apex, texture translucent. Male genitalia as in 
S. austera, n. sp., except that the rami of the paraphyses are narrower and less 
divergent. 
Ground color of dorsum pale brown (darker brown on crown and pronotum 
in holotype), a transcoronal stripe through the ocelli, a transpronotal stripe 
that is interrupted in some specimens (holotype), a diagonal stripe in base of 
clavus and a narrow transverse stripe narrowly interrupted at commissural 
margin at claval apex, pale yellow to bluish-ivory; face with a dark spot at 
base of clypeus, remainder of face, thoracic pleura, and legs, pale yellow, un- 
marked except in holotype which is suffused with brown beneath dorso- 
pleural carinae. 
Holotype male and three additional males, Nova Teutonia, Brazil (F. 
Plaumann). The holotype is without a collecting date, two of the other speci- 
mens were collected August 1, 1939 (NCS). Holotype on indefinite loan to 
USNM. 
S. atronasa is very close to S. austera, n. sp., from which it can be separated 
by the dark apex of the head, by the pronotal stripe, and by the form of the 
paraphyses.
