 lima, corpore plus Iriplo longiures ; prothorax sutcis duobus obliquis 

 sulcoque transversa antico ; pedes robusti ; alte anticic pallide lestacecE ;

 prothorax, wiih a shallow furrow between the sockets of the antenna;. Eyes

 arched. Cerci less than one-fourth of the length of the abdomen. Legs 

 siout ; hind femora with about nine small spines on each side, these spines 

 successively increasing in size to the apical one; hind tibia; with eight 

 rather short spines on the outer side and with seven alternate spines on the 

 inner side. I'ore wings pale testaceous, a little shorter than the hind 

 wings; veins luteous. Hind wings blackish, whitish only along the costa 

 and along the exterior border; the six bands are elsewhere confluent and
