 moderately concave, caudal margin moderately arcuate, a distinct 

 rectangulate impressed line mesad ; lateral lobes distinctly longitudinal, 

 the greatest depth, wdiich is caudad, contained once and a half in the 

 length, cephalic margin slightly sinuate oblique, ventral margin 

 slightly emarginate over the coxse and very slightly angulate caudad 

 of this, caudal margin with a distinct rectangulate humeral sinus, 

 otherwise rounded. Tegmina reaching about to the tips of the caudal

 abdominal segment produced mesad into a subtrigonal process which 

 is somewhat bullate; cerci, produced moderately tapering, apex blunt, 

 somewhat depressed, narrowly recurved dorso-mesad, median process 

 strongly produced in a proximal direction parallel with the shaft, 

 acute, no development distad; subgenital plate with a rotundato- 

 angulate emargination, lateral apical angles rather blunt, ventral 

 surface with three subparallel carin£e. Cephalic femora but slightly 

 shorter than the head and pronotum together; median femora twice 

 as long as the pronotum. Caudal femora once and one-third the
