pi. 15, fig. 22, 23 (1897). 

 I have not seen this species, and copy the drawings in the Biologia. It 

 was first recorded by Brunner from Mexico ; and afterwards, more spe- 

 cifically, by Saussure and Pictet, from Cordova, Vera Cruz, and Tabasco. 

 Only the male is known. 



Stmmetropleura Brunner. 



Symmetropleura Brunn., Mon. Phaneropt., 245 (1878). 



Symmetropleura is distinctively characterized by having all the femora 

 spined beneath, and by a very narrow fastigium between the antennce ; 

 there is no pistillate production of the anal segment of the male. It was 

 founded upon three species, found widely separated in North and South 

 America and Africa. The single species in our fauna was known only 

 by the male, the anal segment of which resembles that of Scudderia 

 septentrionalis. 



Symmetropleura modesta. 



Symmetropleura modesta Brunn,, Mon. Phaneropt., 246 (1878). 



Brunner's single specimen was a male and came from Carolina. I 

 have a female from North Carolina. It differs in no respect from the 

 brief description of the male, except that the whole pronotum is ferru- 

 ginous. The ovipositor is rather short, abruptly upturned just beyond 

 the base, the upturned portion feebly tapering, apically well rounded, 

 the margins of the apical half distinctly crenulato-dentate. The follow- 

 ing measurements may be given : Length of body, 20 mm. Pronotum, 

 3.75 mm. Tegmina, 25 mm. Middle breadth of same, 6 mm. Length 

 of hind femora, 16.5 mm. Ovipositor, 5 mm. Middle breadth of same, 

 2 mm. 



PlATTLTRA (TrXaru?, Xvpa), gen. nov. 



Fastigium of vertex anteriorly compressed, but apically almost as 

 broad as the first antennal joint, truncate, contiguous with the frontal fas- 

 tigium. Pronotum with the disk subconcave, broadening from in front 

 backward, the front margin feebly concave, the hind margin a little con- 

 vex, the lateral lobes subvertical, angularly deflexed, especially behind, 

 where there are distinct canthi, the front margin straight and vertical, 

 the posterior angle strongly and broadly rounded. Tegmina subovate,
