304 BRAZILIAN ORTHOPTERA 



with blackish and the lobes largely dark dull yellow-green: caudal tibiae dark 

 dull yellow-green, the proximal portion washed with dark russian green, the 

 spines black tipped: caudal tarsi dark dull yellow-green dorsad. 



Length of body, 21 mm.; length of pronotum, 4.2; greatest (caudal) width 

 of pronotal disk, 3.4; length of tegmen, 9.7; length of caudal femur, 13. 



The type of this most striking species is unique.

 As intimated by us some years ago,*'^ the acquisition of Surinam 

 material enables us to definitely associate Scudder's aequalis 

 with the true flavofasciata (DeGeer) . A female from Paramaribo, 

 Surinam (K. Mayo; A. N. S. P.) fully agrees with DeGeer's 

 description and figure, possessing the very broad pale costal 

 border of the proximal section of the tegmina which is indicated 

 in the original description. Scudder undoubtedly followed 

 Stal's error in considering flavofasciata a purely Brazihan species, 

 as Surinam is clearly given as the locality by DeGeer. In con- 

 sequence Scudder naturalljandicated the more strikingl}-, although 

 narrowly, flavo-fasciate jimhriata^'^ as DeGeer's species. Stal 

 states that DeGeer's type was missing from the series before him. 

 The unique type of Scudder's aequalis is now before us and it is 

 identical with the Surinam specimen and other material now in 

 our hands.
