158 ENTOMOLOGICAL NEWS [Apr., '17 



obtuse-angulate at the apex of the stridulating vein, distad of this the 

 margin is sinuate; stridulating vein much as in amazonicum: base of 

 ulnar vein quite weakly but rather closeW crenulate. proximal section 

 less decidedly than in amazoniciim. Wings very faintly surpassing 

 the apices of the tegmina. 



Disto-dorsal abdominal segment with free margin much as in atna- 

 zonicum, but median emargination less extensive; supra-anal plate?; 

 cerci of the type found in amasonicum, but more incrassate proximad 

 and more slender distad ; subgenital plate moderately produced, mod- 

 erately narrowing, distal margin broadly V-emarginate, styles short, 

 articulate. 



Cephalic femora with three spines on the ventro-cephalic margin ; 

 median femora with two to three spines on the same margin ; cephalic 

 tibiae with slender distal portion slightly longer than the inflated prox- 

 imal section. Caudal femora less than one-half the tegminal length, 

 moderately robust proximad, considerably tapering distad; ventro- 

 external margin with twelve to thirteen spines distributed over its 

 whole length, ventro-internal margin unarmed. 



General coloration of tegmina yellowish oil-green, of the abdomen 

 citron-yellow, of the head and pronotum pale old gold (type) or the 

 tegminal color (paratype). Head with the face whitish, a distinct nar- 

 row postocular line bone brown ; eyes mottled russet and mummy 

 brown; antennae with the proximal and second joint of the color of 

 the face, remaining joints sudan brown, imperfectly multiannulate with 

 threads of argus brown. Pronotum with the caudal section of the 

 disk and lobes washed with greenish; vicinity of the humeral sinus 

 and the median emargination of the caudal margin touched with 

 mummy brown. Tegmina with (type) or without (paratype) three 

 areas of pseudo-desiccation, of a prout's brown tone, these occasionally 

 outlined in fuscous, and one situated near the base of the ulnar vein, 

 another at the base of the median ramus and divided by the ulnar vein, 

 and the third and largest at the bifurcation of the median ramus; in 

 place of these areas the tegmina (paratype) may have numerous scat- 

 tered fine points of fuscous; distal section of costal margin, and to a 

 lesser degree of the sutural margin, beaded with mummy brown ; 

 bounding section of the stridulating field and stridulating vein marked 

 with mummy brown. Limbs ranging from old gold to dull ochraceous- 

 buff, the tibiae and distal extremity of the femora thickly speckled 

 with fine points of fuscous, which are almost entirely absent from 

 the ventral and lateral faces of the caudal tibiae.
