with minute secondaries, the basal and apical primaries often largest, dorso- 
apical margin of each rectilinear or slightly concave, bearing small teeth like 
those on posteroventral margin. 
Selvitsa, new genus, belongs to the Oragua Melichar generic group, dis- 
cussed in the treatment of the latter genus. It differs from all of the other 
genera in the group except Scoposcartula, new genus, in that the ocelli are 
located behind a line between the anterior eye angles. Male pygofer processes 
are usually present in Selvitsa, absent in Scoposcartula. Paraphyses are usually 
absent in Selvitsa; present in Scoposcartula. The pronotum is wider than the 
head in Scoposcartula; narrower in Selvitsa. Similarities between Selvitsa and 
Aguahua, new genus, are discussed in the treatment of the latter. 
The genus Selvitsa occurs in the area from Panama to southeastern Brazil 
and to Bolivia, but series are short, and no specimens have been seen, to date, 
from Colombia and Peru, nor from the Guianas. 
The male genitalia of the lectotype of Tettigonia humeralis Signoret are il- 
lustrated (fig. 545). The present interpretation of Cicadella cinctosula Osborn 
rests on a male specimen compared with a female specimen from the Carnegie 
Museum and labeled “‘holotype’’. Tettigoniella cachabensis Distant is interpreted 
on the basis of a male compared with the female lectotype. 
In the females studied, there are differences in the shape of the first valvifer 
which appear to be specific. These are not illustrated here because not enough 
specimens were available to check the constancy within a given species.
