346 NEW TROPICAL AMERICAN ORTHOPTERA 



similar, tubercle is placed; median carina represented by small, paired, attin- 

 gent folds at several points, obsolete cephalad and caudad: lateral lobes with 

 greatest dorsal length subequal to greatest depth, the latter being between 

 the median spine of the lateral angle and the ventro-caudal angle of the mar- 

 gin of the lobe, the lobe much shallower cephalad; cephalic margin of the 

 lobes with a weak obtuse-angulate emargination cephalad, the margin convex 

 ventrad of this, ventro-cephalic angle broadly rounded, ventral margin sin- 

 uate, particularly over the cephalic coxa, ventro-caudal angle broadly rounded 

 rectangulate, caudal margin very gently arcuate, moderately oblique, humeral 

 sinus acute, deep, slightlj^ curved; surface of lateral lobes folded and bullate, 

 with the sulci deeply incised, the intervening areas inflated and welt-like, a 

 distinct median spine and a large, elongate reniform, bullation caudad of the 

 same especially indicated. Tegmina nearly twice as long as the body, far sur- 

 passing the apex of the caudal femora, coriaceous-reticulate in texture, the 

 surface lichenose-verrucose, the transverse nervures and distad the longitudi- 

 nal veins appreciably thickened and elevated; greatest width of the costal 

 and discoidal fields contained over five times in the greatest length of the teg- 

 mina, the distal section appreciably upcurved, the apex rectangulate costad; 

 costal margin arcuate proximad and distad, straight mesad; sutural margin 

 very gently concave in the distal portion of its length: median vein diverging 

 at proximal third, furcate: stridulating field moderately longitudinal, its 

 greatest width contained faintly more than twice in the length of the field, 

 free margin arcuate, with a slight obtusc-angulation at the apex of the stridu- 

 lating vein, the latter short, slightly oblique, thickened. Exposed portion of 

 wings about twice as long as the pronotal disk, apical margin oblique truncate, 

 apex sutural and acute; surface of exposed portion of wings similar to teg- 

 mina, covered portion of wings membranous. Prosternum transverse, cephalic 

 margin strongly transverse: mesosternum with the lobes wing-like, much nar- 

 rowed along the median line, cephalic margin obtuse-angulate concave, caudal 

 margin concave, lateral margins of lobes oblique, subarcuate: mesosternal 

 foveolae well separated, in a common depression which is transverse and in 

 form resembles half a sharp oval bisected longitudinally: metasternum in- 

 verted broad trigonal, the cephalic margin straight, lateral margins oblique, 

 strongly converging caudad, faintly arcuate, the lobes very narrow and moder- 

 ately reflexed: metasternal foveolae contiguous in a common opening, which 

 is quadrate in proportions, in general form trapezoidal. 



Abdomen short, plump; medio-dorsal line with a series of rounded, node- 

 like, recurved tubercles, which are well developed on the middle segments and 

 become obsolete on the penultimate segment; lateral aspect of abdomen with 

 a series of strumose, rounded tubercles developed along a line which is slightly 

 dorsad of the middle of the segment, these obsolete distad, also a line of low, 

 indistinct swellings ventrad of the more decided .series, free margins of segments 

 sinuate laterad in the vicinity of these buUations; ventro-lateral sections of 

 dorsal tergites rugulose, rather sharply contrasted with the generally smoother 

 dorsal surface; disto-dorsal abdominal segment subarcuate emarginate mesad,
