apically, with a single pair of retrorse processes which appear more anteapical 
than in other species because of the more elongate dorsal apical lobes. Face of 
male with clypeus and clypellus usually dark, clypeus with broad yellow 
lateral margins which extend a short distance onto clypellus in some speci- 
mens. Female abdominal sternum VII with a distinct notch at base of the 
apical convex lobe. 
Holotype male, Chanchamayo, Peru, July 22, 1960, on Gramineae (J. 
Salazar), and a series of additional specimens of both sexes (but mostly 
males), July 21, 22, and 25, some from Gramineae and Leguminosae (J. 
Salazar, C. Ramirez, and D. A. Young) (NCS). Also, 16 males, Monsén 
Valley, Tingo Maria, Peru, December 9, 1954 (E. I. Schlinger and E. S. 
Ross); two males, same data as preceding except December 23 and October 
26; two males, 26 m. east of Tingo Maria, Peru, 1100 m., December 10, 1954 
(E. I. Schlinger and E. S. Ross); one male, 40 m. south of Tingo Maria, ‘Car- 
pish Mts.”, December 28, 1954 (same collectors) (CAS), Also one male, 
Callanga, Peru, bearing a Melichar manuscript name and a ‘‘Typus”’ label 
(HNHM). Holotype on indefinite loan to USNM from NCS. 
T. treva, n. sp., can be separated from other species of the genus by the 
shape of the aedeagus in caudoventral view, considered in combination with 
the multiseriate setae of the male plates. The female is slightly similar to 7. 
chlorella, n. sp., in the discussion of which distinguishing characters are 
treated.

Type-species: Cicadella signatula Osborn. 
Length 6.7-7.7 mm. 
Head strongly produced, median length of crown varying from two-thirds to 
more than eight-tenths interocular width and from four-tenths to slightly less 
than six-tenths transocular width, anterior margin broadly rounded in dorsal 
view, without a carina at transition from crown to face, ocelli located before a 
line between anterior eye angles, each about equidistant from median line and 
adjacent anterior eye angle, crown with a distinct transverse concavity before 
ocelli, without a median fovea, disk without sculpturing or setae, lateral 
clypeal sutures extending onto crown and attaining ocelli; antennal ledges not 
protuberant, in lateral view with anterior margins oblique and convex; 
clypeus convex but flattened medially, muscle impressions distinct, transcly- 
peal suture obsolete medially, clypellus not strongly produced, contour of its 
lower portion more nearly parallel to long axis of body than remainder of 
facial profile. 
Thorax with pronotal width approximately equal to transocular width of — 
head, lateral margins slightly convergent anteriorly, dorsopleural carinae com- 
plete, posterior margin concave, disk sparsely punctate, not pubescent; 
scutellum not striate behind transverse sulcus. Forewing with membrane. in- 
cluding only inner half of inner apical cell and very narrow apical portions of
