 [Theresopolis, Brazil.] 



Misiones. November, 1910. One female. 



This specimen is slightly larger than the original measurements 

 and is very strikingly marked on the pronotum, abdomen, and limbs 

 with seal brown, but otherwise it fully agrees with the description. 



The species is known only from the types and the present specimen. 

 Nannotettix bilineatus n. sp. 



Type: 9 ; Misiones, Argentina. December 10, 1910. (P. Jor-

Allied to N. guentheri and pallidevittatus Brunner from Sorata, 

 Bolivia, but differing from the former in the paler face, the absence 

 of black from the pronotum, in the broadly ovate instead of lanceolate 

 tegmina, in the fewer femoral spines, the different subgenital plate and 

 shorter caudal femora and ovipositor; from the latter in the non- 

 tuberculate cephalic margin of the pronotum, the fewer femoral 

 spines, the different coloration of the femora and abdomen and the 

 longer tegmina. The striking yellowish postocular lines are sirhilar

 limbs and abdomen will immediately separate the present species. 



Size medium; form rather elongate. Head with the vertex 

 slightly declivent; fastigium acute, reaching to the margins of the 

 antennal scrobes, margins distinctly elevated dorsad of the ocelli, 

 the apex of the fastigium of the front not in contact with that of the 

 vertex; face gently and roundly retreating; eyes subglobose, slightly 

 directed cephalad, indistinctly flattened laterad; proximal antennal 

 joint elongate, armed disto-laterad with a distinct spine. Pronotum 

 with the length of the disk nearly twice the caudal width of the same ; 

 cephalic margin of the disk arcuato-truncate, caudal margin moder-
