CICADELLINAE: PART 2. NEW WORLD CICADELLINI 683 
each corium opposite claval apex; face and propleura concolorous with crown, 
otherwise with venter and legs dark brown with paler sutures and leg joints. 
Holotype male and three females and one specimen without abdomen, 
Tucurrique, Costa Rica (Schild and Burgdorf); one male, Cerro Campana, 
Panama Province, Panama, September 19, 1951 (F. S. Blanton) (USNM). 
One pair in copula and one specimen with apex of abdomen missing, Suiza, 
Turrialba, Costa Rica (P. Schild) (OSU). One male and one female, Bogota, 
Colombia (Lindig) (RMS). 
S. opaca, n. sp., is similar to S. abrupta, n. sp. (below), in the discussion of 
which distinguishing characters are treated. 
Schildola abrupta, NEW SPECIES 
FIGURE 556, PAGE 684 
Length of male 7.6 mm. Head with median length of crown slightly more 
than one-half interocular width and three-tenths transocular width; antennal 
ledges slightly protuberant; clypeus weakly punctate, other head characters as 
in §. opaca, n. sp. Pronotum and forewings as in opaca. Male pygofer weakly 
produced, without a dorsal angle, apical margin broadly convex, macrosetae 
numerous, located on posterior two-thirds of disk; plates with multiseriate 
macrosetae; style apex truncate; aedeagus shorter and slightly more decurved 
than in opfaca; paraphyses essentially symmetrical (but may appear asym- 
metrical because rami extend at different angles), the rami curved, broadened 
apically and obliquely truncate. Female unknown. 
Head, pronotum, and scutellum shining black with a median quadrate 
yellow spot at apex of crown; forewings dark with a larger spot on corium 
bordering claval suture in its basal half, a minute spot near commissural 
margin in apical half of clavus and an interrupted oblique line on corium 
touching base of outer anteapical cell, ivory; face, propleura, and legs, black 
to dark brown. 
Holotype male, Bafios, Ecuador, 2300 meters, May 28, 1939 (W. Clark- 
Macintyre) on indefinite loan to USNM from NCS. 
S. abrupta, n. sp., is similar to S. opaca, n. sp., above, but differs in the form 
of the male pygofer, the aedeagus and in the rami of the paraphyses, as well 
as in the setal arrangement of both pygofer and male plates. 
Schildola ductilis, NEW SPECIES 
FiGURE 557, PAGE 684 
Length of male 7.6-8.4 mm. Head with median length of crown varying 
from slightly less than one-half to slightly more than one-half interocular 
width and from three-tenths to almost four-tenths transocular width; an- 
tennal ledges slightly protuberant; clypeus not flattened medially, texture 
coarsely granular; other head characters as in S. opaca, n. sp. Pronotum as in 
opaca; forewings with veins less distinct than in opaca. Male pygofer weakly 
produced, without a dorsal angle, apical margin subtruncate, macrosetae few,
