Acrulogonia and Tubiga. Pygofer processes are absent in males of Ovagua, except 
O. partitula (Jacobi); present in Acrulogonia. Setae are more numerous on the 
male pygofer of Oragua than in species of Acrulogonia. The clypeus is punctate 
in Oragua, except in O. stylata (Signoret); granular in all species of Acrulogonta. 
The crown is coarsely punctate in Oragua, except in stylata and yuracensis, n. 
sp.; without punctures in Acrulogonia. The forewings are strongly opaque in 
Oragua, usually translucent in Acrulogonia. 
My interpretation of Tettigonia congruens Fowler is based on a study of the 
male lectotype and a single male specimen agreeing with my illustrations of 
the lectotype. The additional specimen was intercepted on an orchid by the 
USDA at Brownsville, Texas, in 1966. It differs in the apices of the para- 
physes (fig. 523). 
The present interpretation of Cicadella discoidula Osborn is based on my ex- 
amination of the holotype. 
The lectotype of Tettigonia nebulosa Signoret is a female from Pernambuco, 
Brazil. Although it has served to make clear the identity of the genus, I have 
not been able to identify it with any of the other species included here. From 
the Melichar collection in Brno, I have examined two specimens determined 
as nebulosa by him; one from Pozuzo, Peru without an abdomen, the other a 
female from Bella Vista, Brazil and near O. obscura (Schréder). Specimens 
labeled ‘“‘nebulosa”’ by Osborn belong to the species treated here as O. osborni, 
n. sp., but neither Melichar’s specimens nor Osborn’s were from the type-lo- 
cality or very near it, as far as I can learn (but see type-locality of osborni 
(below)). 
The type of Cicadella notulatula Osborn in CM is an anomaly of doubtful sex. 
It is close to O. discoidula (Osborn). 
The type of Tettigella obscura Schréder agrees with the illustrations here (fig. 
518). I have identified Tettigoniella partitula Jacobi in the sense of the female 
lectotype. My interpretation of Tettigonia stylata Signoret is based on speci- 
mens from northern Brazil agreeing with Signoret’s illustration and with 
sketches I made of the female lectotype. The paraphyses of this species are 
variable. 
My interpretation of Tettigonia variolosa Signoret is based on a study of the 
male lectotype. 
Tettigonia velutina Fowler is known to me only from the female lectotype, and 
a female compared with the lectotype.
