CICADELLINAE: PART 2. NEW WORLD CICADELLINI 195 
transocular width. Pronotum with posterior margin slightly convex, disk 
sparsely and irregularly punctate, scutellum not striate behind transverse 
sulcus. Hindleg with femoral setal formula 2:1:1, length of first tarsomere 
greater than combined length of second and third tarsomeres. Other non- 
genital structural characters as in A. invenusta, n. sp. 
Male pygofer well produced for the genus, posterior and posteroventral 
margins broadly convex, without processes, with a few large and a number of 
small macrosetae located on posterior and posteroventral portions. Plates not 
extending as far posteriorly as pygofer apex, each triangular, with a few un- 
iseriate macrosetae on basal half. Style with distinct preapical lobe and slight 
apical hook. Aedeagus broad in lateral view, keeled laterally, in caudoventral 
view with shaft broadened apically, with apical margin broadly convex. 
Female unknown. 
Color of crown, pronotum, and scutellum, bright yellow, with a median 
semicircular spot at base of crown and an oval one at apex, black; an arcuate 
linear marking near anterior margin of pronotum, a broader transverse ar- 
cuate marking on posterior half of disk and the median line between these, 
purple; scutellum with fumose area at each end of transverse sulcus; fore- 
wings concolorous with anterior dorsum, veins except in membrane, an obli- 
que line on each wing extending from apex of inner claval vein postero- 
laterally to costal margin, a transverse line across wing before claval apex 
with its posterior margin extending angularly posteriorly, and apical portion 
of anteapical cells, fuscous. Face, thoracic pleura, and legs, pale yellow, apices 
of first and second legs and tibial apices of hindlegs, black.

Biol. Expl., 1921-22. 
A. venata, n. sp., is similar in form to A. pulchra (Fabricius), but differs in 
that the male pygofer lacks a dorsal process, and in that the aedeagus is 
broader in lateral view and conspicuously different at apex in caudoventral 
view.

Length of male 14.5-15.4 mm, of female 14.0-14.9 mm. Head with median 
length of crown from four-tenths to approximately one-half interocular width 
and from one-fourth to approximately one-third transocular width. Pronotum 
with posterior margin weakly convex or weakly concave (holotype). Hindleg 
with length of first tarsomere equal to or slightly greater than combined 
length of second and third tarsomeres. Other non-genital structural characters 
as in A. invenusta, n. sp. 
Male genitalia as in A. venata, n. sp., except that all macrosetae of pygofer 
are large, and that aedeagus has a prominent lobe on anterior margin of each 
dorsal apodeme (fig. 141/) not present in venata and that the aedeagal apex is 
different in caudoventral view. Female abdominal sternum VII much as in the
