CICADELLINAE: PART 2. NEW WORLD CICADELLINI Suk? 
clypeal sutures extending onto crown, not attaining ocelli; antennal ledges 
with anterior margins vertical in lateral view, carinate dorsally or not, clypeus 
slightly convex or slightly flattened medially, muscle impressions distinct or 
not; face not pubescent beneath, transclypeal suture indistinct, clypellus not 
tumid. Thorax with pronotal width equal to or greater than transocular width 
of head, dorsopleural carina extending anteriorly as far as eye margin, fore- 
wing coriaceous with veins distinct or not. 
Male pygofer moderately produced, apical margin abruptly rounded, with 
few sparse anteapical macrosetae, without processes; plates not extending as 
far posteriorly as pygofer apex, without dorsal lobe in lateral view, each in 
ventral view abruptly tapered in basal half, with uniseriate macrosetae and a 
number of microsetae; style extending posteriorly approximately as far as 
apex of connective, with distinct preapical lobe and with apex subtruncate; 
connective subtriangular with a Y-shaped heavily sclerotized portion; 
aedeagus arched dorsally except apex which is curved slightly postero- 
ventrally, without processes; paraphyses with stalk approximately as long as 
rami. Female abdominal sternum ‘VII with posterior margin slightly produced 
and rounded medially (see also generic description). 
Crown pale to dull yellow, usually unmarked, anterior pronotal margin bor- 
dered with chocolate brown (type) to buff, remainder of pronotum bright 
(type) to sordid green; scutellum brown to buff; forewing bright (type) to sor- 
did green, in type marked with brown in midclavus and in wing bases and 
anteapically; color of face variable, clypeus usually yellow marked with a pair 
of darker stripes and bordered broadly with black laterally and ventrally, the 
black including all of clypellus; thoracic pleura and legs, yellow. 
Holotype male and one female, “Porto Platon”’, Terr. Amapd, Brazil, Sep- 
tember 18, 1957 (John Lane) (in Lane collection). Two males, Archidona, 
Ecuador (USNM). Two additional males, Archidona, Ecuador (MMB). 
Externally, M. vinnula, n. sp., is similar in appearance to M. olivatula (Osborn) 
but it differs in the shape of the male plates and in the length of styles. 
Mesogonia suspecta, NEW SPECIES 
Length of male 6.6-7.5 mm. Head with median length of crown from 
slightly less to slightly more than one-half interocular width and approx- 
imately one-third transocular width, ocelli located behind a line between an- 
terior eye angles, each closer to median line of crown than to adjacent an- 
terior eye angle, crown concave before ocelli and behind anterior carina; an- 
tennal ledges with anterior margins concave in lateral view; clypeus with mus- 
cle impressions distinct; face sparsely pubescent beneath, transclypeal suture 
distinct or not. Thorax with pronotal width approximately equal to trans- 
ocular width of head, dorsopleural carina extending anteriorly to eye margin; 
forewing coriaceous with veins not very distinct. Other external structural 
characters as in M. retrorsa (p. 489). 
Male pygofer not strongly produced, dorsoapical margin convex, with a few 
anteapical discal macrosetae, without processes; plates extending as far as or
