342 NEW TROPICAL AMERICAN ORTHOPTERA 



V-shaped emargination; caudal margin of disk broad obtuse-angulate with 

 the angle broadly rounded, the margins laterad faintly emarginate and as a 

 whole narrowly cingulate: median carina not indicated on the prozona, faintly 

 marked on the metazona ; prozona occupying about three-fifths of the dorsum 

 of the pronotum; transverse sulci complete, finely impressed: lateral lobes of 

 the pronotum with greatest depth contained one and one-third times in the 

 greatest dorsal length of the same; cephalic margin of the lobes moderately 

 oblique sub-truncate, ventro-caudal angle obtuse, ventral margin broadly 

 obtuse-angulate, the median angle of same rounded, cephalic section weakly 

 concave, ventro-caudal angle rounded, caudal margin oblique truncate; sulci 

 deeply impressed on the lateral lobes. Tegmina coriaceous, with close net- 

 work of veins, the general longitudinal veins evident, abbreviate, falling slightly 

 short of the distal margin of the proximal abdominal segment, narrowly non- 

 attingent mesad, faintlj' shorter than the disk of the pronotum, short lanceolate 

 elliptical in form, the greatest width contained one and seven-tenths in the 

 greatest length of the same: costal margin strongly arcuate except in the 

 proximal section, where it is nearly straight, sutural margin moderately arc- 

 uate, apex narrowly rounded rectangulate. Wings rudimentary. Prosternal 

 spine conical, apex blunted, slightly retrorse in general direction: interspace 

 between the mesosternal lobes faintly longitudinal, strongly widening caudad, 

 the lobes obliquely truncate, with meso-caudal angle obtuse: metasternal lobes 

 very narrowly separated. 



Abdomen moderately compressed proximad, apex moderately elevated, 

 non-clavate: furcula minute, attingent, verj' short and blunt fingers: supra- 

 anal plate trigonal, the proximal breadth slightly greater than the median 

 length, margins sinuato-convergent, the apical section blunter, obtuse-sub- 

 rectangulate, the immediate apex rounded; surface of the plate elevated medio- 

 longitudinally, the distal section more ampliate, proximad there is indicated 

 for about one-third of the length of the plate a deep, rounded sulcus, the 

 vicinity of which is roughened and haired, laterad the surface of the plate is 

 broadly, rather deeph* and regularlj- concave : cerci short, not reaching to the 

 apex of the supra-anal plate, in general form falciform, very broad and com- 

 pressed at base, regularly narrowing to the distal third, which is relatively 

 slender — that is one-fourth as broad as the base — upcurved and with the apex 

 blunt ; when seen from the dorsum the cerci are straight in the proximal two- 

 thirds, rather sharply though obtusely incurved at distal third, straight 

 oblique thence distad: subgenital plate moderately elongate, conical, acumi- 

 nate, dorsal margins straight when seen from the side, ventro-distal line in 

 profile regularly straight ascendant, viewed from the dorsum the margins 

 converge regularly to the relatively narrowly rounded apex: pallium slightly 

 elevated proximad. 



Cephalic and median femora considerably inflated: caudal femora two and 

 one-half times as long as the dorsum of the pronotum, subcompressed, moder- 

 ately slender, greatest depth contained four times in the greatest length; ex- 

 ternal paginae regularly sculptured, genicular lobes broadly rounded: caudal 

 tibiae slightly shorter than the caudal femora, armed on the external margin
