CICADELLINAE: PART 2. NEW WORLD CICADELLINI 717 
There are a number of topotypic females at hand, but I haven’t associated 
these with the males with any certainty, for two males of S. nielsoni, n. sp., 
were found with the same collection data. 
S. skeeleae, n. sp., can be distinguished from other species in the genus by 
the branched rami of the paraphyses. I am pleased to name this species for 
Sue Skeele, who helped greatly in proof-reading part 1 of this study, and who 
typed most of it. 
Sibovia festana, NEW SPECIES 
FIGURE 587 
Length of male 5.3-6.3 mm, of female 5.6-6.1 mm. Head well produced for 
the genus, median length of crown from slightly more than three-fourths of, to 
equal to, interocular width, and from slightly less than one-half to ap- 
proximately six-tenths (type) transocular width, crown with a very slight 
transverse concavity before ocelli, clypeus not or only slightly flattened 
medially, transclypeal suture obsolete at middle. Pronotum with width ap- 
proximately equal to transocular width of head, posterior margin slightly con- 
cave. Pygofer moderately produced for the genus, setal arrangement as des- 
cribed in S. carahua, n. sp.; plates not extending nearly as far posteriorly as 
pygofer apex; style extending posteriorly approximately as far as apex of con- 
nective; connective with stem slightly longer than arms; aedeagus without 
processes, shaft broad through most of its length. Female abdominal sternum 
VII as in carahua. 
Color of crown, pronotum, and scutellum as in S. Auasima, n. sp. (above); 
forewing colored as in Auasima, but without three transverse short black marks 
in costal area near its apex; inner apical cell smoky subhyaline except near in- 
ner margin, the smoky area extending laterally as a band and narrowing 
across second, third, and fourth apical cells near their midlength to costal 
margin, and a similar narrower apical band, with a transverse opaque yellow 
band separating the two dark bands, and another similarly colored transverse 
yellow band extending across bases of second, third, and outer apical cells 
and to costal margin; color of face and venter as in huasima. 
Holotype male and one female, Popayan, Colombia, 1760 m., April 15, 
1948 (Pfaff); two males and one female, San Esteban, Venezuela, November 
22-30, 1939 (P. Anduze) (USNM). Five females and one male, Palmira, 
Colombia, August 8, 1958, on ‘“‘Grama brava” (a grass) and ‘‘Doltchos”’ (a 
genus of legumes); three females, Manizales, Colombia, September 16, and 
October 22, 1959 (R. F. Ruppel) on Dolichos sp.; two females Juananbu, 
Nayarit, Colombia, February 1, 1960 (B. Yanguatin), on legumes; one male, 
Sasaima, Cundinamarca, Colombia, April 1, 1961, 1500 m. (RFC). 
Since the above was written, I have seen additional specimens from beans 
and from ‘‘Soya” from Colombia, and from cacao from Ecuador.
