CICADELLINAE: PART 2. NEW WORLD CICADELLINI 427 
Male with crown black except lateral margins of antennal ledges, pronotum 
amber with a transverse bilobed black spot in basal half, scutellum black ex- 
cept apex which is narrowly amber, forewings each dull red to claval apex, 
remainder fumose and enclosing a dull red spot before apical cells, face black 
except narrow pale margin at transition to crown, that broadens and extends 
below antennal ledge on each side onto genae; proepisternum and a small ad- 
joining spot on tan proepimeron, black, mesepisternum pale dorsally, remain- 
der of pleura, and venter, black, prothoracic legs stramineous, remaining legs 
mostly black. Female entirely tan dorsally except faint tinge of red on fore- 
wings, varying in extent, face as in male except that antennal ledges are pale 
and pale marginal area is broader, thoracic pleura and venter as in male, legs 
pale, with posterior femora and tibiae (except the knees) dark in two of the 
three specimens at hand. 
Holotype male and one female, taken in copula, Alto de las Cruces, W. Cor- 
dillera [Colombia?], and two additional females, same locality (MMB). 
P. detecta, n. sp., is closely related to P. angrana, n. sp., but the convex 
crown, before the ocelli, differs from all other species of Platygonia. 
58. PALINGONALIA, new GENus 
FiGuRE 347 
Type-species: Tettigonia bigutta Signoret (1854a:6). 
Length 7.2-7.6 mm. 
Head slightly produced, median length of crown from slightly less than one- 
half to almost six-tenths interocular width and from one-third to four-tenths 
transocular width, anterior margin broadly rounded in dorsal view, without a 
carina at transition from crown to face, ocelli located slightly before a line be- 
tween anterior eye angles, each approximately equidistant from median line of 
crown and adjacent anterior eye angle, crown without a concavity between or 
before ocelli, surface finely granulate, lateral clypeal sutures extending onto 
crown and attaining ocelli; antennal ledges not protuberant, in lateral view 
with anterior margins oblique and rectilinear; clypeus convex, muscle impres- 
sions distinct. 
Thorax with pronotal width equal to transocular width of head, lateral 
margins slightly convergent anteriorly, dorsopleural carinae complete, 
posterior margin concave, disk not of only obscurely transversely rugulose; 
scutellum not or only obscurely transversely rugulose behind transverse 
sulcus. Forewing with membrane including all apical cells (venation obscure 
in specimens at hand). Hindleg with femoral setal formula 2:1:1, length of 
first tarsomere slightly greater than combined length of more distal tarsomeres 
(plantar setae not observed). 
Male genitalia: Sternum VIII deeply emarginate medially, with a convex 
lobe on each side of the concavity. Pygofer very short, convex apically, with a 
group of macrosetae before posterior margin, without processes. Plates very 
short and broad, partly concealed by lobes of sternum VIII in ventral view, 
each with uniseriate macrosetae. Style very short, truncate apically, with a
