CICADELLINAE: PART 2, NEW WORLD CICADELLINI 999 
new genus, and to Ghlorogonalia ultima, n. sp. They are green with the head, 
anterior portion of the pronotum, and the scutellum yellow, but the face and 
often the clypeal muscle impressions visible from a dorsal view, are orange. 
The females have much sharper apices of the second valvulae than in 
- Caldwelliola, and are fairly close to Graphogonalia, new genus. The elongate fine 
setae at the apices of the male plates in Crossogonalia will distinguish it, 
without dissection, from the species of Chlorogonalia, new genus and 
Caldwelliola that look similar, and also from Graphogonalia species. The short 
sternal abdominal apodemes and symmetrical paraphyses of the males are 
also diagnostic for Crossogonalia. 
My identification of Crossogonalia hectica (Signoret) is based on a study of the 
female lectotype, and a male compared with it. 
135. SEGONALIA, NEw GENus 
FicurE 813 
Type-species: Segonalia steinbachi, new species. 
Length of male 5.2 mm, of female 5.3-5.5 mm. 
Head slightly produced, with anterior margin broadly rounded in dorsal 
view, median length of crown varying from slightly less than six-tenths to 
almost two-thirds interocular width and from slightly more than one-third to 
_ four-tenths transocular width, without a carina at transition from crown to 
face, ocelli located on a line between anterior eye angles, each ocellus closer to 
adjacent anterior eye angle than to median line of crown, crown not or scarce- 
ly concave across ocelli, without a median fovea and without sculpturing or 
setae, lateral clypeal sutures extending onto crown and attaining ocelli; anten- 
nal ledges not protuberant, in lateral view with anterior margins oblique and 
convex; clypeus flattened medially, muscle impressions distinct or not, trans- 
clypeal suture entire, clypellus with profile continuing contour of clypeus. 
Thorax with pronotal width less than transocular width of crown, lateral 
margins parallel, dorsopleural carinae complete or not, disk not sculptured, 
without pubescence; scutellum not transversely striate behind transverse 
sulcus. Forewing without a distinctly delimited membrane, with bases of three 
_ anteapical cells located proximal to claval apex, with four apical cells of which 
base of outermost is more proximal than base of third, without an anteapical 
plexus of veins; forewings of female in rest position exceeding apex of ovi- 
positor. Hindleg with femoral setal formula 2:1:1, length of first tarsomere 
greater than combined length of two more distal tarsomeres and with two 
parallel rows of small setae on plantar surface. 
Male genitalia: Pygofer moderately produced, attenuate and angulate 
apically, with macrosetae located on apical half, pygofer processes absent. 
Plates short, triangular, fused basally, not extending posteriorly as far as 
pygofer apex, each with uniseriate macrosetae. Style not extending posteriorly 
nearly as far as apex of connective, narrowed and truncate apically, without 
an anteapical lobe. Aedeagus with dorsal apodemes not nearly as long as 
shaft which extends posterodorsally and with its apex bearing a short median
