nearly reaching the tip of the third and in the male that of the fourth 

 abdominal segment, their apex rounded, the veiriing peculiar and 

 profuse, giving to these organs the appearance of being closely and 

 regularly punctulate. All the legs short and heavy. Posterior femora

 nated, moderately slender in the male, more robust in the female.

 acuminate, its disk bulging, rugose, the basal third nearly covered by 

 two large flat attingent, triangular teeth, projecting from the hind 

 margin of the preceding segment. Cerci moderately long and slender, 

 evenly tapering from base to apex. Prosternal spine of medium size, 

 pyramidal, directed gently to the rear, the apex a little blunt, espe-

 narrower than long, in the female one-half, in the male one-third, 

 as wide as the lobes themselves. 



General color flavo-testaceous, more or less streaked and mottled 

 on head and pronotum with brunneous and olivaceous. Tegmina 

 pale brunneo-flavous. Antennae fuscous, the apex of each joint 

 pallid, giving them a strongly annulated appearance. In the female

 with a wide longitudinal dull brown band which is bordered on each 

 side by one of dirty testaceous; sides of head and lateral lobes of 

 pronotum alternately and irregularly longitudinally streaked with dark 

 olivaceous and testaceous. Face, pleura, and external face of hind
