CICADELLINAE: PART 2. NEW WORLD CICADELLINI 785 
much as in J. juninensis, n. sp.; anal tube with a slender acute process at apex 
of segment X; style with a distinct preapical lobe; aedeagal shaft becoming 
abruptly wider near midlength in ventral view, with a short median unpaired 
acute process; paraphyses as in /. ucaya, n. sp. 
Color as in juninensis but with transverse castaneous submarginal stripe of 
pronotum bordered with black anteriorly and with commissural stripe of fore- 
wing changing gradually to red posteriorly; face, thoracic pleura, venter, and 
legs, dull brown. 
Holotype male (pygofer missing), Oxapamba, Peru (USNM). 
I. devia, n. sp., is closely similar to juninensis, in the discussion of which 
distinguishing characters are treated. 
104. TETTISAMA, new GENus 
FIGURES 638, 639 
Type-species: Tettigonia bisellata Signoret. 
Length of male 10.5-10.9 mm, of female 10.0-12.0 mm. 
Head with crown moderately produced, its median length from one-half to 
more than six-tenths interocular width and from one-third to slightly more 
than four-tenths transocular width, anterior margin regularly convex in dorsal 
view, without a carina at transition from crown to face, ocelli located slightly 
closer to adjacent eye angle than to median line of crown, surface convex ex- 
cept for shallow concavity between ocelli, without sculpturing or setae, lateral 
clypeal sutures extending onto crown and usually attaining ocelli; antennal 
ledges each with anterior margin obliquely convex in lateral view; face slightly 
flattened medially, muscle impressions not very distinct, lower portion of 
clypellus weakly pubescent, transclypeal suture usually interrupted medially. 
Thorax with pronotal width greater than transocular width of head, lateral 
margins convergent anteriorly, dorsopleural carinae rectilinear, nearly 
horizontal, complete or nearly so, hind margin broadly, shallowly concave, 
disk without sculpturing or pubescence; scutellum not striate. Forewing with 
membrane of variable extent, often not sharply delimited at base, veins not 
elevated, usually not very distinct, with four apical cells of which base of 
fourth is more proximal than base of third, without a plexus of veins, texture 
coriaceous, without sculpturing; female with forewings in rest position ex- 
ceeding apex of ovipositor. Hindleg with femoral setal formula 2:1:1, first tar- 
somere with length greater than combined length of second and third tar- 
someres, with two longitudinal rows of minute setae on plantar surface. 
Male genitalia: Pygofer moderately produced, dorsal margin with a narrow 
anteapical emargination delimiting an apical undifferentially sclerotized sub- 
quadrate lobe, macrosetae sparse, of mixed lengths and located on disk before 
lobe. Plates separate throughout their length, each narrowly triangular, 
rounded apically, with uniseriate macrosetae (occasionally with one or a few 
setae out of line). Style extending posteriorly farther than apex of connective, 
with slight lobe near midlength, apical portion abruptly narrowed to angulate 
tip which is directed mesally. Connective linear, strongly keeled. Aedeagus
