CICADELLINAE: PART 2. NEW WORLD CICADELLINI 667 
Male pygofer not strongly produced, posterior margin vertical, with a taper- 
ing acute process arising near its midlength, extending mesally and slightly 
basally, crossing median line, with very few submarginal macrosetae near 
hind margin and a large number of minute microsetae on ventral half of disk; 
plates extending posteriorly as far as or slightly beyond pygofer apex, each 
with a number of short macrosetae which are mainly uniseriate; style ex- 
tending posteriorly much beyond apex of connective, with a weak preapical 
lobe; connective short, Y-shaped, the stem not as long as arms which are not 
widely divergent; aedeagus slender, elongate, with shaft almost straight, bi- 
furcate apically; paraphyses absent. Female abdominal sternum VII as in S. 
cachabensis (Distant) (fig. 5412). 
Color of crown, pronotum, and scutellum sordid brown with a short me- 
dian line at apex of crown, and several additional indistinct spots on crown 
and pronotum paler yellow, disk of crown suffused (type) or not with orange 
near each inner ocellar margin; forewing translucent gray, with veins broadly 
dark, with an irregular transverse fuscous band near midlength of corium not 
attaining costal margin nor claval suture, with brachial cell only (type) or in 
addition with band along costal margin, expanding apically into anteapical 
cells, dull orange; female with a slender bright orange mark along claval 
suture near its base; clypeus and clypellus brown, clypeus with a median 
narrow yellow stripe, bordered with darker brown; lora, genae, thoracic 
pleura, and legs, dull yellow to brown. 
Holotype male, Porto Bello, Panama, May 13, 1911 (August Busck) and 
one female, Barro Colorado, Panama Canal Zone, March 14, 1929 (S. W. 
Frost) (USNM). 
S. buscki, n. sp., is closely related to S. cachabensis (Distant), from which it 
differs in its more mesally directed pygofer processes, its longer apical 
aedeagal processes, and in its color. The species is named in honor of August 
Busck, formerly a curator of Lepidoptera at the U. S. National Museum.

Male pygofer not strongly produced, posterior margin abruptly rounded 
dorsally, without processes, with a number of macrosetae in a broad row 
parallel to posterior margin; plates not extending posteriorly nearly as far as 
apex of pygofer, each with a few lateral macrosetae near midlength and a 
number of much smaller multiseriate macrosetae in apical half; style ex- 
tending posteriorly slightly beyond apex of connective, without a distinct
