dorsad and distad, narrowly rounded disto-ventrad, sigmoid ventrad: 

 supra-anal plate well hidden, acute-angulate in form: cerci very short, 

 simple, styliform, faintly sinuate, apex blunt: subgenital plate of the 

 elongate, specialized tj^De found in the genus, compressed; when 

 seen from the side the plate is narrowed at the distal third, thence 

 strongly compressed, the dorsal margin arcuate-emarginate with the 

 dorsal angle acute produced; distal margin oblique sinuato-truncate, 

 the disto-ventral angle produced, bluntly angulate, ventral margin 

 angulato-arcuate; when seen from the venter the plate is regularly 

 narrowing distad, the proximal half with a distinct median carina, the 

 distal half narrowly fissate, the apex of the fissure narrowly broad- 

 ened; when viewed from the dorsum the branches of the plate are 

 seen to be thickened and inflated from the basal excavation of the 

 plate to the disto-dorsal angle, or in the section which is arcuate- 

 emarginate when seen from the side. Cephalic femora with three 

 spines on the ventro-cephalic margin and four on the ventro-caudal 

 margin; cephalic tibiae with five spines on each ventral margin ex- 

 clusive of the apical ones. Median femora uhspined on margins; 

 median tibiae with two spines on the ventro-cephalic margin. Caudal 

 femora of the usual type, with nine very small spines on the ventro- 

 external margin and six of the ventro-internal margin. 



General color honey yellow, the wings weakly washed with chamois, 

 parts of the head, lateral lobes of the pronotum and limbs tending 

 toward clay color. Eyes walnut brown. 



Length of body, 12.4 mm.; length of pronotum, 3.3; greatest width 

 of pronotum, 1.6; length of tegmen, 12.4; greatest A\idth of tegmen, 

 1.6; length of caudal femur, 9.1. 



In addition to the type we have before us four paratypic males, all 

 from Bartica, British Guiana (H. S. Parish; March 6, 24 and 26; 

 April 15, 1913), in the collection of the Academy. These specimens 

 are all slightly larger than the type, but otherwise inseparable. The 

 number of rami in the costal field of the tegmina ranges from fifteen 

 to eighteen. In these specimens the coloration, particularly of the 

 exposed portion of the wings and distad on the tegmina, is strongly 

 approaching cosse green, the limbs also in part washed with weak j avel 

 green.
