 of the angles slightly arciiato-eniarginate, caudal margin aciite- 

 angiilate, very sharp in the male; median carina moderately ele-

carina very gradually slopes cephalad and caudad, the three trans- 

 verse sulci hardly breaking the line of the carina, metazona half again 

 as long as the prozona; lateral angles very distinct, regularly but\ot 

 greatly diverging caudad ; lateral lobes with the dorsal length slightly 

 greater than the depth, ventro-cephalic angle obtuse, ventro-caudal 

 angle rounded rectangulate. Tegmina exceeding the apices of the 

 abdomen and of the caudal femora, a]>out two and two- 

 thirds times the length of the dorsum of the pronotum, 

 rather narrow; costal lobe distinct, well rounded, remain- 

 der of the costal margin straight except toward the apex, 

 where it is considerably arcuate, sutural margin straight, 

 the apex narrowly rounded. Prosternal spine strongly 

 compressed, decidedly retrorse at the apex, the tip slightly 

 blunt ; interspace between the mesosternal lobes narrow, 

 decidedly longitudinal ; interspace between the metasternal 

 lobes small, slightly longitudinal in the male, subquadrate 

 in the female. Subgenital plate of the male acute, com- 

 pressed, with a slight ventral carina. Cephalic and median 

 limbs slender. Caudal femora one and three-fourths 

 (female) to one and four-fifths (male) times the length of 

 the dorsum of the pronotum, rather slender, dorsal and 

 ventral carina serrulate, pagina with the pattern moder- 

 ately regular, genicular lobes acute; caudal tibia? distinctly 

 but not greatly shorter than the femora, armed on the ex- 

 ternal margin with thirteen to fifteen spines, one of 

 which is apical, on the internal margin with twelve to thirteen spines, 

 those of the internal margin being longer than those on the external 

 margin and slightly curved. 



General color ochraceous in the male, clay color in the female.
