Bruner : South American Acridoidea. 15 



Habitat. — A single 9, the type, Corumba, Brazil, whin- it was 

 taken during April by II. II. Smith. 



There are two males of this genus before me which possibly belong 

 to this species. They approach quite closely to those which are un- 

 hesitatingly referred to 0. punctata De Geer, but seem to be separable 

 from that species in their more elongate form and slightly longei 

 wings, in one of them surpassing the apex of the abdomen by fully 

 one-third of their length. One of the specimens has the dorsal portion 

 of the tegmina pale grass-green, while the other follows closely the 

 coloration as described for the female. The carina? of the pronotum 

 here, as well as in the female, are pallid, and are bordered within on the 

 hind lobe by a widening streak of black as is frequently the case in 

 members of the genus. 



The measurements of these males are as follows: Length of body, 

 14.5 mm., of pronotum, 3 mm., of tegmina, 15-15. 5 mm., of hind 

 femora, 8.5-9 mm. 



Habitat. — Corumba, Brazil, March. One of them bears the addi- 

 tional label "highlands."

This is the most abundantly represented species of the genus, and 

 specimens are at hand from all the Brazilian localities at which Smith 

 collected. Much variation in color and also considerable in size is 

 observable among the material at hand. The species was taken 

 practically throughout the year. 



12. Orphulella meridionalis Bruner.

 Habitat. — Costa Rica and southward. Not contained among the 

 material now reported upon. 



13. Orphulella costalis Walker.

Habitat. — It is barely possible that individuals of the insect de- 

 scribed as Stenobothnts costalis by Walker are at hand among the two
