•severed once and then by the transverse sulcus, which is placed very 



slightly cephalad of the middle, subparallel caudad to this sulcus, 



thence slightly diverging to the caudal margin; transverse sulcus of 



a V-shaped form mesad; lateral lobes with the greatest depth 



contained about twice in the greatest (dorsal) length of the same, 



•cephalic margin nearly straight, ventro-ceplialic angle nearly rectan- 



gulate, ventral margin arcuato-sinuate cephalad and arcuately 



expanded caudad, rounding into the oblique, slightly arcuate caudal 



margin, transverse sulcus impressed dorsad. Tegmina with their 



length subequal to that of tlie dorsum 



of the pronotum, their greatest width 



(not flattened) subequal to their length; 



costal margin straight with the disto- 



costal angle well rounded, distal margin 



bluntly arcuate, passing broadly without any

of male type (12) and sutural margin obliquely truncate, at the 



female allotype (13). extremity of the stridulating vein slightly 



produced, rotundato-rectangulate; marginal 

 field very narrow; discoidal field with a fine, irregular network of 

 veins; stridulating vein slightly oblique, slightly arcuate; tympanum 

 very faintly outlined, trigonal, the sharpest angle directed meso- 

 proximad; proximal portion of the anal field (i.e., proximad of the 

 stridulating vein) closely but rather coarsely areolate. Abdomen 

 •quite plump; disto-dorsal abdominal segment strongly arcuato- 

 emarginate laterad by the bases of the cerci; supra-anal plate 

 forming a transverse lappet which has its greatest length contained 

 about three times in its greatest width, distal margin of same truncate, 

 broadly arcuate laterad; cerci simple, heavy, slightly depressed, 

 distal portion of the cercus and median tooth decidedly depressed, 

 the distal portion of the cercus tapering, acute, the immediate apex 

 verj' fine, clawlike and slightly hooked, median tooth placed on the 

 •external face of the cercus, broad, 'bluntly lanceolate, reaching about 

 half way from the i^oint of its origin to the apex of the cercus, closely 

 apposed to the shaft of the cercus for the greater portion of its length ; 

 subgenital plate moderately elongate, V-shaped in section, distal 

 half with the margins moderately and regularly convergent, distal 

 extremity deeply V-emarginate, the emargination extending slightly 

 more than a fourth the way to the base of the plate, laterad of the
