CICADELLINAE: PART 2. NEW WORLD CICADELLINI 563 
clypellus which are entirely black except near their lateral limits (holotype); 
pleura of pro- and mesothorax, mesosternum, apices of tarsi, and male plates, 
black, remainder of venter and legs pale. 
Holotype male, Chanchamayo, Peru, July 22, 1960 QJ. Salazar) (NCS). 
Seventeen males, Monsén Valley, Tingo Maria, Peru, December 9, 1954 (E. I. 
Schlinger and E. S. Ross) (CAS). Three males, Yungas de Palmar, Bolivia, 
100 m., November 1960 (A. Martinez) (SSM). 
F. pachaca, n. sp., differs from other species in the genus in the crossed para- 
physes. The form of the aedeagus is similar to that of F. lativittata (Fowler), 
but narrower and not distinctly bisinuate as in the Fowler species. 
Fusigonalia decurvata, NEW SPECIES 
FIGURE 462, PAGE 562 
Length of male 5.4-5.5 mm, of female 5.7-5.8 mm. Head with median 
length of crown varying from six-tenths to slightly more than three-fourths in- 
terocular width, and from slightly more than one-third to slightly more than 
four-tenths transocular width, antennal ledges in lateral view with anterior 
margins convex. Thorax with pronotal width greater than transocular width 
of head. Male plates each with macrosetae uniseriate; style extending 
posteriorly farther than connective, narrowly rounded at apex; aedeagus ex- 
tending caudodorsally, shaft abruptly broadened in basal half in lateral view, 
the broadened portion with a weak concavity in dorsal marginal midlength, 
apex very broadly and very slightly convex; paraphyses with each of the two 
rami broadly branched and appearing C-shaped in caudoventral view. 
Crown with median black vitta not as broad as in F. melanota, n. sp. 
(above), its lateral margins subparallel except at apex, the median vitta at 
posterior margin of head with width much less than combined widths of 
yellow vittae which separate it from the anteocular black vitta on each side; 
the pale vittae extending posteriorly over pronotum, becoming green or 
greenish on posterior part of pronotum, to include yellow basal scutellar 
angles and to unite with pale claval vitta which is green; corial vitta green or 
greenish-yellow and extending anteriorly almost as far as axillary sclerites; 
transverse anteapical band not interrupted, extending from costal margin into 
inner apical cell, midcostal marking amber or lacking; median vitta narrower 
along claval commissure than in other species of Fusigonalia, and the claval 
pale vitta correspondingly wider; face with black anteocular band extending 
ventrally along anterior margins of antennal ledges and continuing ventrally 
on clypeus about half distance to transclypeal sulcus; remainder of face, 
pleura and venter pale except a black area on proepimeron below dorso- 
pleural carina and additional black areas on mesothorax. 
Holotype and three additional males, 5 m. north of Volcan, Panama, 
December 6, 1952 (F. S. Blanton); two males and one female, Mojinga 
Swamp, Panama CZ, September 1, 1953 (F. S. Blanton) (all in USNM). 
F. decurvata, n. sp., differs markedly from other species of Fusigonalia in the 
narrower claval portion of the fusiform vitta, the greenish tint of the claval 
and corial pale vittae, and in the form of the paraphyses of the male.
