CICADELLINAE: PART 2, NEW WORLD CICADELLINI 1013 
1950 (N. L. H. Krauss) (all USNM). Thirteen specimens, Rancho Grande, 
near Maracay, Venezuela 1946: three males and two females, March 28; one 
specimen without abdomen, March 25; one male, April 24; one male and one 
specimen without abdomen, June 11; two females, June 17; one female, June 
26; and one female, without date (Bronx Zoo). 
C. tiarae, n. sp., is most closely related to C. bonita, n. sp., both of which 
have two pairs of pygofer processes. The processes are more widely separated 
in tiarae and the aedeagus is also distinctive. 
Coronigoniella rubiella, NEW SPECIES 
FIGURE 827, PAGE 1016 
Length of male 7.5 mm. Head with median length of crown less than six- 
tenths interocular width and from slightly more than one-third to approxi- 
mately four-tenths transocular width, ocelli each approximately equidistant 
from median line of crown and adjacent anterior eye angle, crown with trans- 
verse concavity weak, clypellus with contour of its lower portion more nearly 
horizontal than profile of remainder of face. Hindleg with length of first tarso- 
mere not or only slightly greater than combined length of two more distal tar- 
someres. Male pygofer rounded apically, with a pair of slender, elongate, 
acute processes arising basiventrally and extending posterodorsally almost to 
apical pygofer margin; plates extending posteriorly almost as far as pygofer 
apex, each with uniseriate macrosetae; style extending posteriorly approxi- 
mately as far as apex of connective, truncate apically; aedeagus with a ventral 
preatrial portion which projects slightly posteriorly beneath base of shaft as 
an unpaired ventral process, shaft with ventral margin convex in lateral view, 
shaft narrowed and slightly recurved at apex. 
Crown with a conspicuous large apical black spot, otherwise with color as 
in C. bonita, n. sp.; pronotum as in bonita but paler green (type) or not, with a 
group of indistinct black markings near and parallel to anterior margin; fore- 
wing as in bonita but with orange costal strip extending through outer apical 
cells into base of inner apical cell; face, thoracic pleura and legs yellow. 
Holotype male, Barro Colorado Island, Panama Canal Zone, May 19, 1967 
(D. M. DeLong and C. A. Triplehorn) and one male, Suiza, Turrialba, Costa 
Rica (P. Schild) (OSU). 
C. rubiella, n. sp., is larger than other species in the genus. In addition to 
the characters used in the key, the forewings of rubiella have the base of the 
outer anteapical cell located beyond the claval apex (brachial cell exceeds 
claval apex) and the length of the first hind tarsomere equal to, or only 
slightly longer than combined length of more distal tarsomeres. 
Coronigoniella ostenta, NEW SPECIES 
FicurE 820, pace 1010 
Length of male 6.0-6.8 mm. Head with median length of crown slightly less 
than two-thirds interocular width and from four-tenths to slightly less than
