CICADELLINAE: PART 2. NEW WORLD CICADELLINI 767 
Fonsecaiulus gaudialis, NEW SPECIES 
FIGURE 627 
Length of male 5.6-5.7 mm, of female 5.9 mm. Head with median length of 
crown varying from approximately seven-tenths to slightly more than eight- 
tenths interocular width and from slightly less than one-half to one-half trans- 
_ocular width. Male pygofer with a short apicoventral angular process extend- 
ing mesally, style narrowed and truncate apically; aedeagus rounded apically; 
without processes, paraphyses longer-stalked than in F. sciotus, n. sp., with 
each of the rami bifid and with the ultimate branches of somewhat com- 
parable length. Female abdominal sternum VII with posterior margin trans- 
verse and slightly concave, almost rectilinear, genital chamber with dorsal 
wall extensively sclerotized, and with a pair of more distinct, small sclerites 
flanking gonopore. 
Head and pronotum longitudinally striped with yellow and chestnut-brown, 
the median pale vitta extending almost to apex of scutellum; clavus of fore- 
wing with a yellow border that is very narrow except near base of claval 
suture where it is as broad as the lateral pronotal pale vitta of which it is a 
continuation, remainder of clavus castaneous with a short thin yellow stripe 
parallel to claval suture; corium concolorous with disk of clavus, with an 
elongate vitta of varying width bordering and parallel to brachial cell, the 
vitta broader anteriorly and posteriorly than near its middle, and with two 
very small widely-spaced pale spots between this and costal margin. Face, 
pleura, venter, and legs, yellow. 
Holotype male and two females, ‘‘Las Trincheras’”’, D. F., Venezuela, on 
Vernona sp., April 16, 1939 (C. H. Ballou); one male and two females, Los 
Teques, Venezuela, March 14, 1938, ‘on Eugenia jambos”’, and one male, 
Rancho Grande, Aragua, July 5, 1968 (J. Maldonado Capriles) (all USNM). 
F. gaudialis, n. sp., can be most readily separated from other species in the 
genus by the form of the aedeagus of the male.

FIGURES 628-633 
Erythrogona Melichar, 1926a:373. Type-species: Cicada laeta Fabricius, by original 
designation. 
Length 5.4-9.2 mm. 
Head moderately produced, median length of crown from usually slightly 
more than one-half to two-thirds (rarely as much as eight-tenths) its in- 
terocular width, and from slightly less than one-third to slightly more than 
four-tenths transocular width, anterior margin rounded in dorsal aspect, 
without a carina at transition from crown to face, ocelli located on or slightly 
behind a line between anterior eye angles, each approximately equidistant 
from median line of crown and adjacent anterior eye angle, disk with slight 
transverse concavity between ocelli, disk without sculpturing or setae, lateral 
clypeal sutures extending onto crown and attaining ocelli; antennal ledge with
