CICADELLINAE: PART 2. NEW WORLD CICADELLINI 313 
Ground color of dorsum as in vanvelzeni, median pronotal spot touching 
posterior margin in type, almost completely absent in other specimen at hand, 
forewings with both bands attaining costa, both with a narrow sector on each 
wing adjacent to costa, anterior band extending forward to humeral margin 
thence almost to wing base without interruption, apex of forewings fumose. 
Holotype male, St. John’s Valley, Trinidad, February 10, 1929 (J. G. 
Myers), “B.M. 1929-170”, and one female, without legs, Trinidad, January 
13, 1929 YJ. G. Myers), ““B.M. 1929-170” (BM). 
S. myersi, n. sp., is similar in structure to S. vanvelzeni, n. sp., but differs in 
the form of the pygofer and of the aedeagus of the male, and in the color 
characters as stated in the description. The species is named in honor of John 
G. Myers who contributed much to our knowledge of auchenorrhynchous 
Homoptera and who collected the only specimens I have seen. 
47. Genus TACORA MELICHAR 
Ficures 257-258 
Tacora Melichar, 1926a:359. Type-species: Tettigonia dilecta Walker, by original designa- 
tion. 
Length 12.4-15.6 mm. 
Head strongly produced, median length of crown varying from slightly 
more than three-fourths to almost equal to interocular width and from slightly 
more than four-tenths to slightly more than five-tenths transocular width, an- 
terior margin broadly rounded in dorsal view, without a carina at transition 
from crown to face, ocelli located behind a line between anterior eye angles, 
each slightly closer to median line of crown than to adjacent anterior eye 
angle, crown without a 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 oblique and rectilinear; clypeus convex, muscle impressions distinct, 
transclypeal suture obscure, clypellus not strongly produced, its contour con- 
tinuing profile of lower portion of clypeus and more nearly horizontal than 
upper portion of clypeus. 
Thorax with pronotal width greater than transocular width of head, lateral 
margins convergent anteriorly, dorsopleural carinae complete, posterior 
margin slightly concave, disk without sculpturing or pubescence; scutellum 
not striate behind transverse sulcus. Forewing with membrane including all of 
apical cells except short basal portions of second, third, and fourth, veins in- 
distinct except at wing apex, with four apical cells of which base of fourth is 
more proximal than base of third, without an anteapical plexus of veins, tex- 
ture of clavus coriaceous, of corium varying from entirely coriaceous to mostly 
translucent, without sculpturing; forewings of female in rest position ex- 
ceeding ovipositor. 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 strongly produced, strongly narrowed dorsoapically 
into a slender acute process which extends mesally towards or across median
