CICADELLINAE: PART 2. NEW WORLD CICADELLINI 359 
Tipuana expallida, NEw SPECIES 
FIGURE 272 
Length of male 10.4 mm. Head moderately produced, median length of 
crown seven-tenths interocular width and one-half transocular width, anterior 
margin more narrowly rounded in dorsal view than 7. chirensis. Forewings 
missing. Other external characters as in chirensis. Male pygofer produced 
posterodorsally and truncate, with macrosetae near posterior margin and ex- 
tending anteroventrally near posteroventral margin; style with preapical lobe 
not as distinct as in chirensis and narrowly rounded at apex; connective with 
arms not broad; aedeagus with a pair of curved apicoventral short acute 
processes and a pair of dorsoapical acute curved processes that are similar to 
each other in form but not in symmetrical planes; paraphyses short with rami 
asymmetrical. 
Crown, pronotum, and scutellum dull yellow, with a pair of longitudinal 
narrow brown lines extending full length of crown between ocelli, a pair of 
shorter similar parallel lines between these, an oblique similar line extending 
anteromedially from each eye and crossing suture before ocellus, and a very 
short narrow oblique black stripe near margin of antennal ledge, the longest 
lines of the crown continuing over pronotum to its posterior margin; pro- 
notum also with a darker line parallel to and near lateral margin. Face, 
thoracic pleura, venter, and legs pale yellow with a dark line below dorso- 
pleural carina. 
Holotype male, Hacienda Maria, Cuzco, Peru, February 22, 1952 (F. L. 
Woytkowski), along Rio Cosnipata, 900 m., on indefinite loan to USNM from 
NCS. 
As noted above, 7. expallida would have been the type-species of Tipuana 
had Melichar completed his work. The single male in HNHM agreed with 
the present illustration. I did not select this as type-species because the speci- 
men at hand is without forewings. 7. expallida is closely related to T. chirensis 
in the discussion of which distinguishing characters are treated.

Figures 275-296 
Type-species: Tettigonia ignota Walker. 
Length of male 6.0-8.5 mm, of female 5.9-7.9 mm. 
Head moderately produced, median length of crown from slightly more 
than six-tenths of, to almost one-fourth greater than interocular width, and 
from four-tenths to two-thirds transocular width, anterior margin narrowly 
rounded or subangulate in dorsal view, without a carina at transition from 
crown to face, ocelli slightly variable intraspecifically in location, on or 
slightly before a line between anterior eye angles, and each equidistant, or 
nearly so, from median line and adjacent anterior eye angle, crown with a 
median full-length longitudinal fovea, without sculpturing or setae, lateral 
clypeal sutures extending onto crown and attaining ocelli, antennal ledges not 
protuberant, in lateral view with anterior margins rectilinear and oblique;
