apex and contained slightly less than four times in the length ; costal 

 margin moderately arcuate, apex acute, the sutural margin straight 

 with the apical fourth obtusely deflected to the apex, which consider- 

 ably exceeds the tip of the subgenital plate. Tegmina of the female 

 lanceolate, exceeding the tips of the caudal femora by about the length 

 of the head, greatest width about a third the distance from the apex, 

 which is acute ; greatest width contained about six and a half times in 

 the length; costal margin arcuate distad, the sutural margin straight 

 for about four-fifths the length, the apical fifth obliquely deflected 

 to the apex. Wing of the male very nearly two-thirds the length of 

 the tegmen; costal margin strongly arcuate, the apex rectangulate ; 

 hyaline ulnar area with the width contained about two and a half 

 times in the width of the entire wing, complete transverse veins eight 

 in number. Interspace between the mesosternal lobes very distinctly 

 longitudinal in the male, subquadrate in the female; interspace be- 

 tween the metasternal lobes narrow, slightly longitudinal in the male, 

 transverse quadrate in the female. Abdomen more distinctly com- 

 pressed in the male than in the female; male subgenital plate enor- 

 mously produced, compressed, the apical section needle-like, the length 

 equal to that of the pronotum. 



Cephalic and median limbs slender, femora very slightly arcuate in 

 the male. Caudal femora very slender and elongate, the greatest 

 width in the male being about nine times in the length, about eight 

 and a half in the female, exceeding the tip of the subgenital plate 

 proximal portion hardly inflated, but almost regularly tapering to the 

 apex, carinse distinct, pattern of the pagina distinct, acute-angulate and 

 but shallowly impressed, genicular lobes in both sexes produced, the 

 dorsal angles of the genicular region produced into broad, somewhat 

 flattened, acute-angulate processes, in the male that of the internal 

 face over twice the length of the external and as long as the femoral 

 depth, in the female the processes of the two sides subequal; caudal 

 tibise slender, very slightly shorter than the femur, lateral margins 

 with seventeen to eighteen spines in the male, nineteen in the female; 

 tarsi with rather small arolia. 



General color dorsad russet sprinkled and washed with mummy 

 brown, ventral color pale cinnamon. Head in the male with the cari- 

 nse spotted with mummy brown and two rather faint postocular lines 

 of the same color present; eyes in the male mars brown, in the female 

 Vandyke brown. Pronotum with a pair of irregular dark bars on the 

 lateral carinse. Tegmina in the male liberally sprinkled with small 

 mummy brown and bistre maculations. Wings with the costal margin
