in the length of the same; lateral angles indicated by callous ridges 

 similar to those on the head, sinuate on the cephalic 

 half, considerably diverging caudad, distinct but not 

 at all strong humeral shoulders developed caudad, a 

 very fine medio-longitudinal sulcus present on the 

 dorsum; cephalic margin very slightly arcuato-emargi- 

 nate, caudal margin considerably arcuate ; lateral lobes 

 with the greatest depth contained one and one-third 

 times in the length of the same, ventral margin sinuato- 

 arcuate, ventro-caudal angle subtruncate, humeral 

 sinus rotundato-rectangulate. Tegmina about one and 

 one-half times as long as the body, greatest width of the 

 marginal and discoidal fields contained about six times 

 in the tegminal length, the width gradually narrowing 

 to the middle, thence subequal to the well-rounded apex; 

 marginal field with its greatest width at the proximal 

 third, where jt is but little narrower than the adjacent 

 portion of the discoidal field, gradually narrowing thence 

 to practically the apex; costal transverse nervures near the base of 

 the marginal field forked, simple distad, all subcallose, oblique; 

 median vein diverging distinctly distad of the middle of the discoidal 

 vein, short, sinuate, oblique, reaching the sutural margin; rami of 

 the discoidal vein three in number, similar to the median vein in 

 form, length, and direction, two reaching the sutural margin, the 

 third reaching the apex; anterior ulnar vein with five veins similar 

 to the others of the discoidal field in character and direction, the 

 anterior ulnar vein far removed from the posterior ulnar vein and 

 close to and subparallel with the discoidal vein; tympanum with 

 the stridulating vein very strong, slightly oblique, speculum trig- 

 onal, the margin little produced at the apex of the stridulating vein. 

 Exposed portion of the wings slightly longer than the pronotum, 

 sutural margin straight, costal margin rounding to the apex which 

 is sutural in position. Lobes of the mesosternum and metasternum 

 broadly rounded. Disto-dorsal abdominal segment produced, trun- 

 cate, considerably emarginate laterad at the bases of the cerci; 

 supra-anal plate slightly elongate, trigonal, the apex well rounded;
