dorsum moderately deplanate in transverse section; disk with the 

 lateral margins indicated by a weak angle as well as by color, angle 

 weakest mesad, arcuate inbowed, most approximate at the transverse 

 sulcus which is slightly cephalad of the middle; greatest caudal 

 width of dorsum about two-thirds the greatest length of same; 

 •cephalic margin subtruncate, very weakly emarginate mesad, caudal 

 margin very gently arcuato-emarginate ; transverse sulcus impressed 

 in, an obomegoid figure mesad, faint cephalic and caudal traces of a

hjngitudinal sulcus; lateral lobes of the pronotum with greatest 

 depth contained one and two-thirds times in the greatest dorsal 

 length of same, cephalic margin straight, ventro-cephalic angle 

 narrowly rounded rectangulate, ventral margin gently arcuato- 

 emarginate, the greatest depth of the lobes caudal, ventro-caudal 

 angle and caudal margin moderately arcuate except the dorsal por- 

 tion of the latter which is truncate. Tegmina somewhat inferior to 

 pronotum in length; costal margin straight, disto-costal angle well 



rounded, distal margin slightly oblique, 

 truncato-arcuate, sutural margin rect- 

 angularly produced at the extremity 

 of the stridulating vein, distal portion 

 of the same margin obliquely sinuato- 

 truncate; marginal field rather nar- 

 row, discoidal field regularly expand- 

 ing from the proximal third, anal vein 

 straight and not arcuate, anal field 

 with the greatest leagth but little more 

 than greatest width, stridulating vein slightly arcuate, tympanum 

 proper poorly defined. Alxlomen with lateral margins subparallel, 

 •disto-dorsal abdominal segment strongly transverse, the greatest 

 length of the same not more than one-fifth its greatest width,
