CICADELLINAE: PART 2. NEW WORLD CICADELLINI 129 
transocular width, anterior margin very broadly rounded in dorsal aspect; 
ocelli located behind a line between anterior eye angles and each ap- 
proximately equidistant from adjacent eye angle and median line of crown, 
without a transverse concavity before ocelli; lateral clypeal sutures not at- 
taining ocelli; antennal ledges with anterior margins obliquely rectilinear. Pro- 
notum not transversely rugose; forewing with two membranous areas before 
apical membranous area, veins indistinct in basal half; hindwing with jugal 
lobe very greatly enlarged. 
Pygofer moderately produced, with macrosetae sparse for the genus and ir- 
regularly dispersed on the disk, without processes; plates extending posterior- 
ly beyond pygofer apex, each elongate, triangular, gradually narrowed in 
basal half, with multiseriate macrosetae throughout their length, style ex- 
tending posteriorly considerably beyond apex of connective, without a pre- 
apical lobe; connective short, broadly Y-shaped, with a median keel; aedeagus 
symmetrical, without processes, in lateral view with shaft of equal width 
almost throughout length; paraphyses with a pair of asymmetrical rami aris- 
ing near base. 
Crown and anterior third of pronotum sordid yellow, posterior two-thirds of 
pronotum concolorous or (holotype) pinkish with an arcuate darker trans- 
verse band and a more posterior almost rectilinear transverse band, black, 
posterior margin narrowly black. Scutellum black, with basal angles and an 
arcuate transverse stripe behind and contiguous to transverse sulcus yellow or 
dull red (holotype). Forewing of holotype hyaline with commissural margin of 
clavus and costal margin both narrowly black, with an angulate marking at 
humeral angle, a smaller corial marking extending from costal margin, in 
basal third, and a transverse corial vitta extending from costal margin, 
narrowing across bases of anteapical cells, to inner margin of inner apical cell 
opposite claval apex, black (markings less distinct in second specimen). Hind- 
wing with jugal lobe black, with an arcuate pale marking near its midlength. 
Face yellow, a pair of longitudinal stripes on clypeus, all of clypellus except 
mesal portion of base, and loral sutures, black. 
Holotype male, Surinam (A. Dohrn) and an additional male, also from Sur- 
inam (RMS). 
This species is more robust than any of the other species which have an en- 
larged jugal lobe. D. axillaris, n. sp., is most closely related to D. laetus 
(Walker), but it differs conspicuously in being shorter, in the markings of the 
anterior dorsum and the forewings, and in its shorter aedeagal apodemes. 
Dilobopterus ponerus, NEW SPECIES 
FIGURE 87, PAGE 126 
Length of male 6.2 (type) - 6.6 mm. Head with median length varying from 
slightly less than one-half to slightly more than one-half interocular width and 
from approximately one-fourth to slightly more than one-third transocular 
width, anterior margin more narrowly rounded in dorsal aspect than in D. 
axillaris, n. sp.; ocelli located behind a line between anterior eye angles, with 
area before ocelli very shallowly concave. Forewing hyaline; hindwing with
