Porto Velho, Rio Madeira. (Mann and Baker.) One male. 



This specimen is referred to the present species with some 

 shght misgivings, as the cephaUc femora show httle indication 

 of the "undate" margins originally described, and the caudal fem- 

 ora are hardly "subundate" dorsad. These features, however, 

 show some individual variation in other forms of the group and 

 without additional material it seems best to so consider them here. 

 With all the other characters given for this species the present 

 individual agrees very satisfactorily. 



Bruner has recorded the species from Santarem on the lower 

 Amazon.

Tettigidea pulchella Rehn 



1904. reltigidea pulchella Rehn, Proc. Acad. Nat. Sci. Phila., 1904, p. 669. 

 [Bartica, British Guiana.] 



Para, Para. (C. F. Baker.) One male, one female. 

 The female individual is slightly larger than the type and has 

 the wings surpassing the extremities of the caudal femora by 

 more than the tegminal length, while in the type the wings do not 

 surpass the femoral apices. The male has the wings projecting 

 caudad of the pronotum a distance equal to the depth of the ej^e. 

 This sex also has the face, genae, ventral portion of the lateral 

 lobes and pleura and ventral and distal portions of the abdomen 

 pale ochraceous. The Pard specimens show no other noteworthy 

 differences from the female type.
