CICADELLINAE: PART 2, NEW WORLD CICADELLINI 941 
in krameri. | have been able to separate the two species on the basis of color 
pattern of the scutellum which is variable in krameri, but never with the yellow 
spots as described above for woodrufft. 
A. woodruffi, n. sp., is named in honor of Dr. R. E. Woodruff who collected 
-it and numerous other interesting leafhopper species in Mexico.

FIGURES 762-776 
Type-species: Tettigonia sobrina Stal. 
Length of male 5.6-12.7 mm. 
_ Head very slightly produced, with anterior margin broadly rounded in dor- 
sal view, median length of crown varying from slightly less than one-third to 
six-tenths interocular width and from approximately one-fifth to less than 
four-tenths transocular width, without a carina at transition from crown to 
face, ocelli located on or slightly behind a line between anterior eye angles, 
each ocellus definitely closer to adjacent anterior eye angle than to median 
line of crown, crown convex and without a transverse concavity across ocelli, 
without a median fovea and without sculpturing, without setae, lateral clypeal 
sutures extending onto crown and attaining ocelli; antennal ledges not pro- 
tuberant, in lateral view with anterior margins oblique and usually rectilinear 
(convex in some specimens); face without a vertical lenticular sclerite border- 
ing lateral clypeal suture on each side below eye, clypeus varying from 
strongly convex to flattened medially, muscle impressions not very distinct in 
most species, transclypeal suture obscure near middle, clypellus swollen or 
not, in profile with a portion of its basal half continuing contour of clypeus, 
remainder more nearly horizontal. 
Thorax with pronotal width less than transocular width of head, lateral 
margins parallel, dorsopleural carinae complete, posterior margin varying 
from slightly concave to slightly convex, disk not or usually only obscurely 
sculptured (exception: M. tribunicia (Berg)), not pubescent; scutellum not 
transversely striate behind transverse sulcus. Forewing with membrane clearly 
delimited or not, variable interspecifically in extent; veins distinct or not 
(varying interspecifically), with three closed anteapical cells of which the 
bases of the inner two are usually in the same transverse line, the base of the 
outer anteapical cell occurring slightly more proximally, with four apical cells, 
the base of fourth 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 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: Pygofer strongly produced, apex varying interspecifically 
from narrowly to broadly rounded, with many macrosetae in a group located 
/on posterior half of disk and extending anteroventrally parallel to ventral 
-pygofer margin, pygofer processes absent (the pygofer apex is curved mesad 
and bears characteristic emarginations in M. sobrina (Stal), but is not differen- 
_ tially sclerotized). Plates very short, triangular (exception: M. fritzlla, n. sp.),
