CICADELLINAE: PART 2. NEW WORLD CICADELLINI Tiel 
Willeiana maculoidea, NEW SPECIES 
Figure 133 
Length of male 6.1 mm; female unknown. Crown with median length 
slightly more than four-tenths interocular width and slightly more than one- 
third transocular width; clypeus flattened medially and finely punctate, trans- 
clypeal suture obsolete, pronotum with dorsopleural carinae incomplete. Male 
aedeagus with a lateral keel on each side in basal two-thirds, and dorsal 
margin less strongly convex than in other species of the genus. 
Crown and narrow anterior band of pronotum black with sparse small 
yellow spots and vermiculations, remainder of pronotum purple; scutellum 
black and yellow, the yellow areas consisting of a pair of basal spots and the 
edges of the lateral margins; forewings purple with indistinct narrow longi- 
tudinal black lines; face black with clypeus mottled with yellow on disk and 
with narrow yellow lateral margins; proepimeron mostly dull yellow; legs with 
femora partly black, remainder dull brown. 
Holotype male, Colombia, 1941 (L. Richter), on indefinite loan to USNM 
from NCSU. 
W. maculoidea, n. sp., differs from other species in the genus in its smaller 
size, in its lateral aedeagal keels, and in the less strongly convex dorsal 
margin of the aedeagal shaft. The markings of the head and pronotum are 
fewer and larger than in W. versigonoidea, n. sp., to which it is more similar 
than to the other species of the genus.

Figures 134, 135 
Type-species: Tettigoniella hydra Distant. 
Length 9.2-10.2 mm. 
Head weakly produced, with anterior margin very broadly rounded in dor- 
sal view, median length of crown from slightly less than one-half to slightly 
more than one-half interocular width and from one-fourth to less than one- 
third transocular width, without a carina at transition from crown to face, 
ocelli located behind a line between anterior eye angles, each ocellus ap- 
proximately equidistant from median line of crown and adjacent anterior eye 
angle, surface with a marked transverse depression before ocelli, and a median 
concavity extending from it to posterior margin of head, without sculpturing 
or setae, lateral clypeal sutures extending onto crown and attaining ocelli; an- 
tennal ledges not protuberant, in lateral view with anterior margins oblique 
and slightly angulate; face without a lenticular sclerite bordering lateral 
clypeal suture on each side below eye, clypeus flattened medially, disk with 
vertical striations, muscle impressions distinct or not, transclypeal suture ob- 
solete at middle, clypellus not produced, contour of its lower two-thirds more 
nearly parallel to long axis of body than basal third which continues profile of 
clypeus. 
Thorax with pronotal width less than transocular width of head, lateral 
margins slightly convergent anteriorly, dorsopleural carinae complete,
