 from litiirifroiis in having the pygophor and anal tube much smaller, 

 the anal style shorter and broader and the genital styles less curved 

 and their apices, where they meet, not straight.

 angularly emarginate at apex, ventro-lateral edges of pygophor pro- 

 duced into angular, bent plates; anal segment long, compressed, form- 

 ing a keel along medio-dorsal line, a long, acutely angular depression 

 on ventral basal surface; anal style very small, narrowly lanceolate, 

 genital styles small, slightly curved, flattened, the apices crossing one

This prohably represents a new genns, hut as there appears 

 to be two forms mixed under Ugyops and Bid is which I cannot 

 separate I place this form with them.
