jiixta-ocular arcuate sulci paralleling the eyes; occipital line undulate 

 arcuato-truncate between the sulci, subarcuate laterad; ocelli placed 

 in a triangle, the ventral ocellus larger than the paired ones; facial 

 shield %vith the greatest (median) depth about two-thirds the greatest 

 (ventral) width, the dorsal margin gently arcuate, ventral margin 

 moderately arcuato-emarginate, lateral margins slightly diverging 

 ventrad, surface smooth; eyes little prominent, rotundato-obtuse 

 ccphalo-laterad, gently arcuate laterad, the greatest rndtli of the 

 eyes contained about one and one-half times in their 

 length; antennse simple. Pronotum elongate rectangu- 

 late, the greatest (supra-coxal) mdth contained two and 

 one-half times in the greatest length; cephalic margin 

 well arcuate, slightly flattened niesad, cephalo-lateral 

 angles well rounded; lateral margins cephalad of the coxal 

 insertion subequal to the supra-coxal ^vidth, caudad of 

 the same distinctly but not greatly narrowed, caudal 

 margin arcuate laterad, truncate mesad; disk of the pro- 

 notum with the faintest possible medio-longitudinal sulcus cephalad, 

 an equally faint median carina near the caudal extremity; transverse 

 sulcus at the cephalic third, strongly U-shaped, the arms of the sulca- 

 tion shghtly sinuate and slightly converging cephalad; margins entire. 

 Tegmina with the greatest length about two and one-half times that of 

 the pronotum, slightly surpassing the apex of the abdomen, apex nar- 

 rowly rotundate. Wings ^^dth the costal margin nearty straight, apex 

 rotundato-rectangulate. Supra-anal plate transverse 

 trigonal, angle broadly obtuse, median carina present; cerci 

 depressed, sublamellate, surpassing the subgenital plate, 

 apex missing, proximal joints broader than long; subgeni- 

 tal plate broad, proximad, lateral margins strongly converg- 

 ing caudad, caudal margin very nan'ow, truncate, styles 

 very short, free. Cephalic coxse equal in length to about 

 three-fifths of the pronotal length, unarmed on the margins ; 

 cephahc femora equal to four-fifths of the pronotal length, 

 moderately compressed, dorsal margin subarcuate prox- 

 imad, straight distad, ventro-lateral margin mth five 

 spines, decreasing in length distad, the distal one on the 

 genicular lobe, ventro-internal margin with 13 spines, 

 more or less alternating in length, discoidal spines 4 in 

 number; cephalic tibias (without apical claw) about two-thirds the 

 length of the femora, external margin armed with 10 to 11 spines, 

 internal margin armed with 11 spines increasing in length distad; 

 cephahc metatarsi equal to four-fifths of the tibial length, remainder 

 of the tarsi very slightly shorter than the metatarsi. Median limbs 

 quite short, the femora not more than three-fifths of the pronotal 

 length. Caudal limbs longer than the median ones, the femora but 

 slightly shorter tlian the pronotum.
