Habitat. — Sao Paulo, Brazil. Several specimens contained in II. II. 

 Smith's collection from Chapada are doubtfully referred to Rehn's

Genus Parorphula Bruner. 

 Parorphula Bruner, 2d Rept. Locust. Com. Buenos Aires, pp. 22, 25 (1900). 



The representatives of the present genus are denizens of grassy 

 fields, and range from southern Brazil to the Rio Negro of Argentina. 

 At least four species are known. They may be separated as follows: 

 Synopsis of the Species of Parorphula. 

 A. Tegmina in the male not especially broad. 



b. General color of insect more or less green graminea Bruner. 



bb. General color of insect testaceous varied with brown and fuscous. 

 c. Dorsum of pronotum and dorsal field of the tegmina pallid. 



pallidinota Bruner. 

 cc. Entire body together with the tegmina more or less varied with pale and 



dark streaks strigata Bruner. 



A A. Tegmina of male unusually broad, reminding one of these organs in Cocyto- 

 tettix. Color variable, but never green lalipennis sp. nov. 



The species graminea may be considered as the type of the genus. 



26. Parorphula latipennis sp. nov. 



Readily recognized by the unusually broad tegmina as well as 

 fenestrate anterior area of the wings in the male, which characters at 

 once suggest the genus Cocytotettix Rehn {Fenestra Brunner v. Watten- 

 wyl). The strongly posteriorly divergent lateral carinae of the pro- 

 notum, the absence of the longitudinal carina of the vertex and occi- 

 put, and the rather general infuscation of the wings, along with other 

 characters place it in Parorphula. 



Iliad slightly ascending, about the same length as the pronotum;
