saddle-shaped prouotum is somewhat ampliate rounded laterally in 

 the anterior part, and the hind margin is straight ; with the exception 

 of the face, the body is opaque and very finely aciculate ; the cerci are 

 thick, sub-cylindrical and sharply tapering towards the apex ; the supra- 

 anal plate is shai-ply triangular ; the ovipositor is sabre-shaped, much 

 recurved, nearly four times as long as the width of the base ; anterior 

 tibiae with a double row of six spines each, including the terminal ; 

 but in the non-adult stage these spines are reduced to four, and even 

 to two, one below the drum and the other at apex ; intermediate tibiae 

 with two rows of ten and eight respectively, posterior tibiae closely 

 spinose along their whole length ; anterior and intermediate femora 

 simple ; the hind ones, which are well developed at the base, have each 

 a double series of twelve spines.
