gin nearly straight, ventral margin arcuate in distal half, apex acumi- 

 nate: subgenital plate narrowly fissate-emarginate mesacl. Cephalic 

 tibiae short, broadly fusiform inflated in proximal two-thirds, subequal 

 and subcompressed in distal third; cephalic face with a large elliptico- 

 reniform tympanum, caudal face with a much smaller elliptical tym- 

 panum. Caudal femora subequal in length to the tegmina, moder- 

 ately inflated; caudal tibiae with three pairs of marginal spurs, which 

 are not opposite in their insertion, the external series slightly more 

 proximal in their position when compared with their equivalent on the 

 internal series, the internal spurs faintly arcuate, their dorso-internal 

 edge also faintly thickened, knife-like and pencilled with blackish; 

 disto-external spurs small; disto-internal spurs very much longer, 

 the dorsal one about two-thirds as long as the metatarsus, the dorso- 

 internal margin thickened and pencilled as on the internal marginal 

 spurs; metatarsi slightly longer than the remaining tarsal joints 

 combined, a single spine present at the disto-internal angle, the in- 

 ternal spur of the metatarsus large, reaching almost to the extremity 

 of the tarsus, slightly falcate, with the dorsal edge thickened and 

 pencilled as is the case with the other internal spurs. 



General color ochraceous-buff, the head distinctly and the pro- 

 notum faintly washed with weak russet; eyes clear russet; exposed 

 portion of the wings faintly washed with mummy brown, the veins 

 pale; at distal fourth the cephalic and median femora bear narrow, 

 incomplete annuli of weak mummy brown, indications of a similar 

 one are present on the pregenicular section of the caudal femora. 



Length of body, 4.6 mm.; length of pronotum, 1; greatest (caudal) 

 width of pronotum, 1.3; length of tegmen, 3.7; length of exposed por- 

 tion of wing, 2.7; length of caudal femur, 3.6; length of ovipositor, 1.6. 



The type of tliis species is unique.

Igarape-assii. February 1, 1912 (two). Three females. 



This striking species, which shows great diversity in form between 

 the sexes, has the coloration more generally punctate, from the pres- 

 ent material, than previous descriptions would lead one to suppose. 

 The agreement with the features of the detailed original description is 

 so full there can be no question of the identity, or at the most the 

 very close relationship of the present material. Chopard reported 

 the species from St. Jean du Maroni, French Guiana, and Bruner
