CICADELLINAE: PART 2. NEW WORLD CICADELLINI 81 
clypeus flattened, muscle impressions obscure; face pubescent below, trans- 
clypeal suture obsolete medially, clypellus not produced, its lower portion 
almost continuing profile of clypeus. 
Thorax with pronotal width greater than transocular width of head, lateral 
margins convergent anteriorly, dorsopleural carinae incomplete, posterior 
margin concave, with a transverse concavity near anterior margin delimiting 
an anterior collarlike portion of pronotum, disk with punctures weak and 
sparse, without pubescence; scutellum not distinctly striate behind transverse 
sulcus. Forewing without a membrane, veins not distinct, with four apical 
cells, the base of the fourth more proximal than base of third, without an an- 
teapical plexus of veins, texture translucent. Hindleg with femoral setal for- 
mula 2:1:1 or 2:1:1:1; 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 as in Trichogonia Breddin, except that aedeagal orifice is 
apical and ventral instead of anteapical and ventral, and with basal portion of 
paraphyses distinct. 
Female unknown. 
Cephalogonalia Evans is known only from the type-species, of which I have 
seen specimens from Peru and Bolivia. It is closely similar to Stehlikiana, new 
genus, but is larger, and the male plates lack macrosetae. It is also near 
Trichogonia, but specimens lack a keel at the transition from crown to face, 
and have vein Rais of the hindwing entire, both of which differ from 
Tnchogonia. Generic relationships are discussed further in the treatment of 
Trichogonia. 
My interpretation of Tettigoniella flabellula Jacobi is based on a study of the 
male lectotype.

Figures 48-58 
Apulia Distant, 1908a:525. Type-species. Tettigonia quadrimacula Walker, by original 
designation. 
Apulina Melichar, 1926a:345. Type-species: Tettigonia elongata Signoret, by present 
designation. 
Length 13.3-18.0 mm. 
Head strongly produced, median length from six-tenths to more than eight- 
tenths interocular width and from slightly less than one-half to slightly more 
than one-half transocular width, anterior margin sharply rounded to angulate 
in dorsal view, with or without a carina at transition from crown to face, sur- 
face of crown usually convex except for transverse concavity before ocelli, 
rarely (A. resupinata, n. sp.; A. elongata (Signoret)) with a broad shallow me- 
dian fovea, with or without a concavity laterad of each ocellus, lateral clypeal 
sutures extending onto crown but-usually not attaining ocelli; antennal ledges 
with anterior margins oblique and rectilinear or slightly convex in lateral 
view, usually with a very narrow fovea dorsally; face convex (rarely slightly
