CICADELLINAE: PART 2. NEW WORLD CICADELLINI yt 
One male, 26 mi. east of Tingo Maria, Peru, 1100 m., December 10, 1954 (E. 
I. Schlinger and E. S. Ross) (CAS). 
S. carahua, n. sp., is closely related to S. taeniatifrons (Schmidt) from which it 
may be separated by the form of the aedeagus in lateral view, and by its 
medially directed process of the pygofer. The two species appear to be sym- 
patric. 
Sibovia chanchama, NEW SPECIES 
FiGURE 579, PAGE 712 
Length of male 7.3 mm, of female 8.3 mm. Head moderately produced, an- 
terior margin broadly rounded in dorsal view, median length of crown from 
slightly less than two-thirds (male) to two-thirds interocular width and be- 
tween four- and five-tenths transocular width. Pronotum with posterior 
margin slightly concave or rectilinear. Other external structural characters as 
in S. carahua, n. sp. Male pygofer well produced, with posterior margin 
narrowly rounded, without processes, setae as in carahua; style not extending 
posteriorly as far as apex of connective; connective with stem very much 
longer than arms; aedeagal shaft slender and elongate, slightly broadened in 
basal half in caudoventral view and bearing a short acute retrorse process on 
each side of broader portion, apex curved dorsally in lateral view; paraphyses 
as in S. occatoria (Say) (fig. 589h). Female abdominal sternum VII well 
produced, posterior margin shallowly concave. 
Crown with median portion orange from base to apex, anterolateral 
margins broadly sordid yellow, apex with a black spot; pronotum with two 
poorly defined broad longitudinal stripes from base to apex, orange at their 
anterior portions and concolorous with crown, their remaining portions dark 
green suffused with orange, background narrowly pale anteriorly and 
laterally, remainder green; scutellum orange; forewing dark green, costal 
margin orange-bordered, with a faint longitudinal orange claval stripe and an 
oblique orange band bordered with black anteriorly and posteriorly in apical 
cells, with a narrow black stripe from mid-corium to base of second apical cell 
and with a black vein forming outer margin of middle anteapical cell; face, 
thoracic pleura, and legs stramineous except dark tarsal apices. 
Holotype male and one female, Chanchamayo, Peru, July 25, 1960 (Salazar 
and Ramirez) (NCS). Holotype on indefinite loan to USNM. 
S. chanchama, n. sp., is distinct from other species in the genus in the form of 
the aedeagus which is curved dorsally at its apex in lateral view, and in its 
color pattern. 
Sibovia huasima, NEW SPECIES 
FIGURE 583, PAGE 713 
Length of male 6.1-6.3 mm, of female 6.3-6.6 mm. Head well produced, an- 
terior margin sharply rounded in dorsal view, median length of crown varying 
from almost three-fourths to more than nine-tenths interocular width, and
