cerci simple, tapering, slightly bent near the middle, thence incurved, 

 apex acute, spined; subgenital plate greatly produced, narrowing 

 distad, distal margin deeply arcuato-angulate emarginate, supplied 

 with rather short, distinct styles. Cephalic femora with two to three 

 spines on the ventro-cephalic margin and a single spine on the ventro- 

 caudal one; dorso-caudal margin of the cephalic tibiae with five 

 spines, one of which, is placed on the proximal dilation and the other 

 at the distal extremity, dorso-cephalic margin with only the single 

 distal spine or another additional one. Median femora with three or 

 four spines on the ventro-cephalic margin and one or two on the 

 ventro-caudal one. Caudal femora about three-fourths the length 

 of the tegmina, very slender, ventral margins with seven spines on 

 each, placed on little more than the distal half, genicular lobes bluntly 

 acute, not surpassing the dorsum of the femoral apex,- bispinose; 

 caudal tibise appreciably exceeding the femora in length, all of the 

 margins armed, the dorsal more thickly so than the ventral ones. 



General color oil green passing into clay color on the pleura and 

 abdomen. Head with the frontal fastigium, the base of the labrum 

 and the above-described strumose ridges cream color; eyes cinnamon; 

 antennae washed with saffron yellow. Pronotum faintly washed 

 with chrome yellow, median sulcation and the lateral angles dull 

 cream color, the latter margined ventro-cephalad and ventro-caudad 

 with ochraceous. Tegmina with a faint ochraceous tinge at the base 

 of the humeral trunk; principal longitudinal veins whitish, the 

 transverse veins of the marginal field, the rami of the anterior ulnar 

 vein, the median vein and the rami of the discoidal vein similarly 

 colored, on the marginal field the direct rami of the costales also 

 are similarly colored, the rami of the anterior ulnar vein having their 

 secondary ramifications for a very short distance each side of the 

 main rami also whitish, while the median vein and the rami of the 

 discoidal vein have this more extensive, involving the whole of 

 certain of the minor ramifications, the entire pattern being very 

 decided. Exposed portion of the wings with the principal veins 

 whitish in the same fashion as on the tegmina. Spines on the 

 femora black.
