CICADELLINAE: PART 2, NEW WORLD CICADELLINI 965 
C. gryllsi, n. sp., is very similar to C. trivialis, n. sp., and may be a form of 
the latter, but the differences in size, markings, and aedeagus, without known 
intergrades warrant their treatment as separate species at this time.

Length 5.2-8.4 mm. 
Head moderately produced (exception: H. maestralis (Metcalf and Bruner)), 
median length of crown usually from four-tenths to slightly less than six- 
tenths interocular width (between three- and four-tenths in maestralis) and 
usually from slightly more than one-fourth to slightly less than four-tenths 
transocular width (approximately one-fifth in maestralis), without a carina at 
transition from crown to face, ocelli located slightly before, slightly behind, or 
on a line between anterior eye angles, each closer to adjacent anterior eye 
angle than to median line of crown, crown usually convex, slightly flattened 
medially in some specimens, usually with a shallow transverse concavity 
across ocelli, without a median fovea and without sculpturing or setae, lateral 
clypeal sutures extending onto crown and attaining ocelli; antennal ledges not 
protuberant, in lateral view with anterior margins slightly oblique (almost ver- 
tical) and varying from rectilinear to slightly concave; face usually with a very 
slender subantennal sclerite bordering lateral clypeal suture on each side, 
clypeus convex or slightly flattened medially, muscle impressions usually dis- 
tinct, transclypeal suture usually obsolete medially, clypellus not produced, its 
contour continuing profile of clypeus in its basal portion, apical portion 
usually lying in a plane more nearly horizontal. 
Thorax with pronotal width varying from less than to greater than trans- 
ocular width of head, lateral margins varying from parallel to each other, to 
slightly convergent anteriorly, disk without sculpturing except rarely (then 
with very weak transverse striae), without pubescence; scutellum not striate 
behind transverse sulcus. Forewing with membrane of variable extent, in most 
species including all of apical cells except basal portion of outer apical cell, 
but in some species more extensive and including anteapical cells, and in 
others less extensive and including only first, second, and apical portion of 
third apical cells, veins distinct but not elevated, with only two short closed 
anteapical cells of which the bases are well distad of a line drawn across wing 
through claval apex and perpendicular to long axis of wing, base of fourth 
apical cell much more proximal than base of third, without an anteapical 
plexus of veins, texture coriaceous and without sculpturing; forewing of female 
in rest position exceeding apex of ovipositor. Hindleg with femoral setal for- 
mula 2:1:1 or 2:1:1:1; length of first tarsomere greater than combined length
