CICADELLINAE: PART 2. NEW WORLD CICADELLINI 281 
elongate, almost straight process which is rounded at apex. Female abdominal 
sternum VII with posterior margin slightly convex, with a shallow median ex- 
cision. Other structural characters as in P. lugubris, n. sp. 
Color of dorsum sordid tan to bright yellow with veins of forewings 
darkened or not, with or without orange or deep yellow spots; venter and legs 
concolorous with dorsum. 
Holotype male, a series of additional males and one female, Coroico, 
Bolivia (OSU). 
P. zapala, n. sp., is closely related to P. isabellina (Fowler) but can be 
separated readily from the latter by the form of the apex of the aedeagus and 
the short dorsal spine at the base of the free portion of the pygofer process. 
Paromenia falcata, NEW SPECIES 
FIGURE 216, PAGE 270 
Length of male 13.7-14.1 mm. Head with median length of crown about 
six-tenths interocular width and approximately four-tenths transocular width, 
with a transverse concavity before ocelli, lateral clypeal sutures attaining ocelli 
or not; antennal ledges with anterior margins rectilinear in lateral view; face 
with clypeus slightly flattened medially, muscle impressions distinct. 
Pronotum with hind margin concave; forewing with membrane including 
apical portion of inner three apical cells, texture translucent to opaque, at 
least some of veins of corium darkened, with an anteapical plexus of veins; 
first hind tarsomere with length slightly greater than combined length of 
second and third tarsomeres. Male pygofer with posterodorsal portion 
produced in an undifferentially sclerotized acute process, the posterior margin 
concave beneath it, macrosetae irregularly arranged, a few at base of 
posterodorsal process, and a number on posteroventral portion of disk; plates 
slender, triangular, extending posteriorly. almost as far as pygofer apex, 
macrosetae serially arranged; style gradually expanded apically, the apical 
margin convex; connective broadly U-shaped with a strong median carina; 
aedeagus with shaft broadest near midlength, the apex concave in lateral view 
and with a short angular projection on anterior margin. Female unknown. 
Other structural characters as in P. lugubris, n. sp. 
Color of dorsum amber with coronal muscle impressions, anterior portion of 
pronotum, basal angles of scutellum, at least some of veins in corium and oc- 
casionally the claval veins, a transcommissural area posterior to claval apex, 
smoky; face and venter usually slightly darker than dorsum, with apical por- 
tions of middle and hind femora and all tarsi, dark gray to black. 
Holotype male, Santo Domingo, Ecuador, March 19, 1950 (S. W. Frost); 
four specimens, Santo Domingo, Ecuador, November 6, 1953 (H. Yust); and 
three specimens, Santo Domingo de los Colorados, Pichincha, Ecuador, 2,000 
ft., February 6, 1958 (R. W. Hodges) (USNM). A series of additional 
specimens, some with abdomen missing, from near the type locality and two 
specimens, one mile south of Pisco, Peru (CAS). 
P. falcata, n. sp., is similar to P. tsabellina (Fowler) and P. maculosa, n. sp., in 
the form of the shaft of the aedeagus in lateral view, but differs from both of
