not extending posteriorly one-half distance to pygofer apex, each with a 
regular or irregular row of macrosetae (exception: fritila). Style extending 
posteriorly almost, or completely, as far as apex of connective, truncate or not 
apically, with a lateral lobe located near midlength of shank. Connective Y- 
shaped with arms widely divergent. Aedeagus short, convex dorsally with a 
pair of elongate slender processes arising basiventrally and exceeding apex, 
and with a pair of apicoventral lobes. Paraphyses absent or vestigial (except 
in fritilla). 
Female abdominal sternum VII produced posteriorly and with apex round- 
ed or acute, in some species extending almost as far posteriorly as apex of 
ovipositor. Dorsal membrane of genital chamber without sclerites. Ovipositor 
with second valvulae broadened beyond basal curvature, with teeth triangular 
near base of expanded portion, irregular near apex of basal third of expanded 
portion in some species, quadrate and regular in apical two-thirds, with 
secondary denticles on most of the teeth except basal ones, apices variable, 
but not acute, with a slight preapical ventral concavity in some species (fig. 
762m). Pygofer with a number of macrosetae on posterior third and a smaller 
number arising more basiventrally near ventral margin. 
Most species of Macugonalia are mottled. For most species, the male 
genitalia do not offer diagnostic characters, and the female genitalia are 
similar in several species. The key works consistently for nearly all the 
specimens I have seen. Specimens have been examined from the West Indies 
(a single rare species), Costa Rica, Panama and Trinidad Island southward to 
Bolivia, southern Brazil, Paraguay, and Argentina. Macugonalia is close to 
Apogonalia Evans, in the treatment of which distinguishing characters are dis- 
cussed. 
Species similar externally to Macugonalia are found in the new genera 
Willetana and Versigonalia. The shape of the male pygofer, the short plates, and 
the lack of paraphyses will separate Macugonalia from these and from most 
other similar genera. 
Some specimens of Macugonalia moesta (Fabricius) were swept from alfalfa, 
near Iquitos, Peru, by Young and Juan Gonzalez. A few specimens of M. 
redundans (Fowler) in the USNM were collected on cacao by Barber and 
Schwarz in Guatemala. 
I have not seen any specimen eligible to be the type of Tettigonia dubia 
Signoret (and automatically of its replacement name Macugonalia brasiliensis 
(Metcalf)). The name has been applied to several of the species in the list of 
species, by older authors. 
My interpretation of Cicada contaminata Fabricius rests on specimens from 
Peru, compared with the lectotype. The crown, pronotum, and scutellum are 
mottled yellow and black, but with no large areas of either, the mottling ex- 
tending ventrally on the clypeus to the transclypeal sulcus. The present inter- 
pretation of Tettigonia cavifrons Stal rests on specimens compared with the 
lectotype. This species is greatly variable in size. . 
Tettigonia dallasi Signoret is interpreted here in the sense of the lectotype. Of 
the species which have large spots at the base of the forewings, it is more 
closely inscribed with black on crown and pronotum. A specimen sent to me 
from MHNP labeled “‘semiguttata Sign., Coll. Germ.” appears to be one of
