oblique, sinuato-truncate, humeral sinus rectangulate. Tegmina 

 surpassing the apices of the caudal femora by somewhat more than 

 the length of the pronotal disk, of the peculiar crinkled character 

 found in S. nitida, this being regular proximad in the discoidal field, 

 irregular distad and in the costal field: greatest width of the tegmina 

 at the distal fourth, contained nearly four and three-quarters times 

 in the greatest length; costal margin straight arcuate, briefly arcuate 

 proximad and in the distal fourth; apex well rounded, sutural por- 

 tion of apex oblique subtruncate; sutural margin concavo-truncate : 

 mediastine vein weak but distinct: humeral and discoidal veins not 

 in contact; median vein diverging from the discoidal vein at the 

 proximal third, bifurcate faintly before its middle; ulnar vein bi- or 

 triramose: stridulating field with the free margin but faintly produced 

 at the apex of the stridulating vein, distad of this gently arcuate; 

 stridulating vein nearly transverse, greatly thickened, subfusiform; 

 speculum greatly elongate, narrow, proximad of the stridulating vein 

 the field is subcoriaceous. Wings projecting distad of the tegmina a 

 distance less than the length of the disk of the pronotum, the apex 

 narrowly rounded. Prosternum elevated in a V-shaped structure, 

 unarmed: mesosternal lobes truncate laterad, rounded rectangulate 

 disto-laterad : metasternal lobes narrow, obliquely arcuate. Disto- 

 dorsal abdominal segment arcuate-emarginate laterad, the distal 

 margin subtruncate mesad, a weak medio-longitudinal impression 

 present: subgenital plate deflexed, trigonal: cerci simple, tapering, 

 arcuate dorsad, the apices very briefly spiniform: subgenital plate 

 narrow, produced, attenuate mesad, projecting almost to the tips of 

 the cerci, the distal margin strongly arcuate-emarginate; styles short, 

 articulate. Limbs slender: cephalic femora subcompressed, moder- 

 ately deep; cephalic tibiae with the tympana large, reniform: caudal 

 femora nearly two-thirds as long as the tegmina, moderately inflated 

 proximad, very slender distad, ventro-external margin with six to 

 nine, ventro-internal margin with four spines. 



General color shining blue black, the pubescence of the body and 

 limbs white, the plumosity of the antennae black. Head with a pair 

 of infra-ocular lines of hazel, the clypeus and labrum marked with 

 the same to ochraceous-buff: palpi incompletely lined dorsad with 

 ochraceous-buff: eyes cinnamon-brown. Pronotum with the ventral 

 portion of the lateral lobes narrowly margined with naples yellow. 

 Tegmina faintly buffy hyaline in the proximal three-fourths, distal 

 fourth strongly washed with blackish fuscous; humeral, discoidal, 

 ulnar and anal veins and rami prominently lined with walnut brown
