292 BRAZILIAN ORTHOPTERA 



segment: eyes prominent, their greatest depth more than twice that of the 

 infra-ocular portion of the genae: antennae about three times as long as the 

 dorsum of the pronotum. Pronotum with the lateral lobes faintly deeper in 

 proportion to their length. Tegmina with the greatest width contained nearly 

 six times in their greatest length. Interspace between the mesosternal lobes 

 sublongitudinal, distinctly broadening caudad; interspace between the meta- 

 sternal lobes strongly longitudinal and very narrow. Supra-anal plate large, 

 scutellate, proximal half with the lateral margins subparallel, distal half with 

 the margins sinuato-convergent, making the distal portion sub-rectangulate 

 in form; an elevated double sigmoid carina crosses the plate at the proximal 

 two-fifths, proximad of which the plate is subtectate in section, with the crest 

 of the tectation expanded and subsulcate in the distal two-fifths of the plate: 

 cerci elongate, reaching to the apex of the supra-anal plate, simple, tapering, 

 acuminate, regularly inbowed : subgenital plate with the margin slightly elevated 

 and appreciably compressed disto-dorsad. Caudal tibiae with six to eight 

 spines on the dor so-external margin. 



General color deep blue black, overlaid on the cicatricose and strumose 

 elevations with marmorations of light cadmium to dull ochraceous-orange. 

 Eyes amber brown (cf ) to bay (9); antennae of the general color, narrowly 

 lined laterad on the proximal third with pyrite yellow. Tegmina with the 

 general color more olivaceous black, the venation completely outlined in olive- 

 ocher. Wings weakly washed with fuscous, more thickly so distad and along 

 the periphery, heavily so along the distal two-thirds of the costa; longitudinal 

 veins strongly pencilled with fuscous; proximal portion of the disk washed 

 with jasper red. Abdomen dorsad and laterad garnet brown (cf) to nopal 

 red ( 9 ), the segments more ( 9 ) or less (cf) strongly, broadly and completely 

 banded proximad with black; venter of the abdomen similarly patterned but 

 with the reddish replaced by sanford's brown; apex of the abdomen largely 

 black, ovipositor jaws dull orange. Cephahc and median limbs of the general 

 color, lined on the dorsal and ventral surfaces and at the extremities of the 

 articles with dull orange. Caudal femora of the general color, the dorsal car- 

 inae, a broad bar along the ventro-external carina and the genicular lobes dull 

 orange: caudal tibiae of the general color, weakly lined along the dorso-lateral 

 angles with dull buffy; caudal tarsi lined on the external face with dull pale 

 buffy.
