Female abdominal sternum VII with posterior margin tapering to slightly 
notched apex. Ovipositor with second valvulae each toothed on dorsal margin 
beyond basal curvature, the teeth broad, sloping, and with minute second- 
aries, apex rounded, without anteapical dorsal or posteroventral denticles, 
ventral margin convex, basal curvature slight. Pygofer narrowly rounded 
posterodorsally, with a broad group of macrosetae located parallel to postero- 
ventral margin. 
Oeogonalia, new genus, is known only from the type-species from Colombia 
and Brazil, a dull orange to tan species. I have placed it near Poeciloscarta Stal, 
but it is less similar than the other genera discussed in the treatment of that 
genus. The form of the second valvulae of the ovipositor differs from all of the 
genera discussed there. 
I have seen a male and a female, from MHNP, labeled ‘‘Aulacizes 
fossulata”. Both agree with Signoret’s original illustration (1855b, plate 12, 
fig. 14). I have not seen a specimen (Spinola collection) eligible to be lec- 
totype. 
29. Genus EXOGONIA MeELICHAR 
Figures 181-184 
Exogoma Melichar, 1926a:342. Type-species: Tettigonia assimilis Signoret, by subsequent 
designation of China, 1938d:183. 
Length 8.3-12.0 mm. 
Head slightly to moderately produced, median length of crown varying 
from more than four-tenths to almost two-thirds interocular width, and from 
three-tenths to approximately four-tenths transocular width, anterior margin 
broadly rounded in dorsal view, without a carina at transition from crown to 
face, ocelli located in line with anterior eye angles, each approximately equi- 
distant from latter and median line of crown or slightly closer to adjacent an- 
terior eye angle, crown usually with an anteapical concavity before ocelli (very 
strong in Exogonia assimilis (Signoret), absent in some specimens of E. semivitta 
(Walker)), surface without sculpturing or setae, lateral clypeal sutures ex- 
tending onto crown and attaining ocelli; antennal ledges not protuberant, in 
lateral view with anterior margins oblique and varying from convex (usually) 
to rectilinear or concave (semivitta); clypeus varying interspecifically from 
slightly to strongly flattened medially, muscle impressions distinct or not, 
transclypeal suture obsolete medially, clypellus with profile not angulate, con- 
tinuing contour of clypeus (usually) or with its lower portion more nearly 
horizontal (assimilis), not pubescent. 
Thorax with pronotal width varying interspecifically compared with trans- 
ocular width of head, lateral margins parallel or convergent anteriorly, dorso- 
pleural carinae complete and oblique, posterior margin concave, disk trans- 
versely rugose; scutellum not striate behind transverse sulcus. Forewing with 
membrane varying interspecifically from sharply delimited to indistinct at its 
base, variable interspecifically in extent when present, with three closed an- 
teapical cells, their bases more proximal than claval apex, with four apical
