CICADELLINAE: PART 2. NEW WORLD CICADELLINI 569 
rectilinear. Thorax with pronotal width approximately equal to transocular 
width of head. Male plates with uniseriate macrosetae; style extending 
posteriorly slightly farther than apex of connective which is broadly triangu- 
lar, style narrowly rounded at apex; aedeagus curved abruptly dorsally near 
base of shaft, thence extending posterodorsally, broadened anteapically in 
caudal view, the apex appearing somewhat sagittate in ventral view; para- 
physes slender, tapering, in lateral view curving gradually dorsally, acute 
apically, in caudal view with the rami not widely divergent. 
Crown with median black vitta with lateral margins not convergent until 
just behind apex, the median vitta at posterior margin of head with width less 
than combined adjacent widths of yellow vittae on each side, without an ante- 
ocular black vitta on each side; the yellow vittae extending posteriorly over 
the pronotum to include basal scutellar angles and to unite with greenish- 
yellow claval vitta (see generic description); corial vitta yellowish-green, ex- 
tending basally as far as axillary sclerites; transverse anteapical band entire, 
extending from costal margin into inner apical cell, midcostal marking not 
distinct; face, venter, legs, and pleura, yellow, except a narrow band border- 
ing dorsopleural carina and continuous with lateral pronotal black stripe. 
Holotype male, 3 m. west of Villavicencio, Meta, Colombia, 920 m., March 
11, 1955 (E. I. Schlinger and E. S. Ross) (CAS). One specimen without ab- 
domen, Rio Negro, finca near Villavicencio, Colombia, February 5, 1969 (R. 
E. Dietz IV) (USNM). 
F. metaensis, n. sp., is similar to F. quinquevittata (Taschenberg) in the struc- 
ture of the male genitalia, but differs in that the aedeagus is curved dorsally 
in metaensis. None of the other species of Fusigonalia lack the short anteocular 
black vitta.

Cicadella Latreille, International Commission of Zoological Nomenclature, Opinion 647 
(see Part 1 of present work, ‘Literature Cited”) (name placed on Official List of 
Generic Names in Zoology). 
Length of male 6.5-7.7 mm, of female 8.1-10.3 mm. 
Head weakly produced with anterior margin broadly rounded, without a 
carina or an angle at transition from crown to face, ocelli in line with anterior 
eye angles, surface convex without sculpturing or setae, lateral clypeal sutures 
extending onto crown and attaining ocelli; antennal ledges not protuberant, 
not carinate, in lateral view with their anterior margins oblique and often 
slightly concave; clypeus convex, muscle impressions distinct, transclypeal 
suture distinct, clypellus with contour usually continuing profile of clypeus or 
with its lower portion more nearly horizontal, with short pubescence. 
Thorax with pronotal width less than transocular width of head, lateral 
margins parallel, dorsopleural carinae horizontal or slightly oblique, extend- 
ing only over posterior portion of proepimeron, posterior margin very slightly
