 fine ; pygof ers of the male short ; the genital aperture broadly oval 

 below the anal tube; the dorsal margin strongly reflexed and touch- 

 ing the anal tube dorsally ; genital styles narrow, blunt, their bases 

 contiguous about one-third of the length and then roundly diverging 

 so that their apices are about half of their length apart.

 very large ; calcar large and f oliaceous, marginal teeth stout ; genital 

 aperture elongate, ventral sinus shallow, ventral teeth small, acute, 

 side margins a little inflated ; dorsal angles slightly produced ; genital 

 styles contiguous, horizontal at the ba.se, strongly projecting pos-
