CICADELLINAE: PART 2. NEW WORLD CICADELLINI 191 
_ weakly rugose or not. Forewing with veins slightly elevated. Hindleg with 
_ femoral setal formula 2:1:1. 
Male pygofer well produced, dorsal margin decurved slightly at apex in 
lateral view, posteroventral margin broadly convex, with a number of small 
submarginal macrosetae located in area parallel to posteroventral margin. 
Plates not extending as far posteriorly as apex of pygofer, with uniseriate 
short macrosetae. Style with a small apical hooklike process. Aedeagus broad 
in lateral view, keeled laterally, with a pair of short dorsal processes at base of 
shaft extending laterally at right angles to axis of shaft which is broadest in 
apical half and with apical margin truncate and very slightly concave. Fe- 
male abdominal sternum VII with posterior margin rounded laterally, broad- 
ly produced medially and acute at apex. Other structural characters as in A. 
invenusta, Nn. sp. 
Color of crown, pronotum, and scutellum, dull orange, with an in- 
conspicuous transverse marking at base and a spot at apex of crown, a trans- 
verse stripe across pronotum near posterior margin, purple to black, the area 
behind the pronotal stripe variable in color. Forewings blue with a pair of 
narrow transverse purple stripes, one attaining commissural margin at apex of 
inner claval vein, the other between apex of outer claval vein and claval apex. 
Face and venter concolorous with crown. Legs slightly darker than venter. 
Holotype male, three additional males and four females, Fontebda, 
Amazonas, Brazil; one female, ‘““Olivenca’’, Brazil; and two females, Iquitos, 
Peru (RMS). 
A. binotata, n. sp., is related to A. obscura, n. sp. (above) in the structure of 
the genitalia, but the aedeagal shaft in caudoventral view is more broadly ex- 
panded in the apical half and scarcely narrowed before the apex. It is also 
closely related to A. trinotata, n. sp. (below) in the discussion of which dis- 
tinguishing characters are treated.

Ficure 148 
Length of male 10.0-10.2 mm, of female 10.5-11.0 mm. Head with median 
length of crown from one-third to slightly more than four-tenths interocular 
width and from one-fifth to one-fourth transocular width, clypeus varying 
from slightly convex to slightly flattened medially. Pronotum with disk vary- 
ing from smooth to rugulose or rugose, scutellum with portion behind 
transverse sulcus rugulose or not. Forewing with membrane not fumose 
apically. Hindleg with femoral setal formula 2:1:1. Other characters except 
genitalia as in A. invenusta, n. sp. 
Male genitalia as in A. binotata, n. sp., except aedeagal shaft which is less 
broadened in apical half, constricted anteapically and with apical margin 
angularly emarginate. Female abdominal sternum VII with posterior margin 
broadly produced posteriorly, the margin of the produced portion abruptly 
narrowed to an acute minute apex. 
Color of crown, pronotum, and scutellum, dull orange to sordid yellow, 
with (type) or without a black spot at apex of crown, with a transverse black
