 prolegs are 8 in number. 



The numbers on the single specimen examined were as 

 follows : 



The claws on the thoracic legs have a finger-like, fleshy 

 projection at the base of the teeth. 



Intermediate instars not fully known. No differences from

Length 24 mm. (full-grown female). Width of head-case
