 Upper lateral margin of hypopygium straight; apical process of 

 hypopygium small, inclined cephalad, hidden by claspers except at 

 its base (which is visible beyond end of claspers), slightly widening 

 toward apex; apex truncate and produced above claspers. Claspers

 2.6, 3.8, 2.4 mm. Armature of forefemur with inner row and claws of

 twice its length from tip of trochanter. Basal half of forefemur 

 gradually thickened to first spine. 



Abdomen with bulbous swelling. Apical angles of second to fourth 

 terga not produced. Abdomen gradually widened to middle of fourth 

 segment. Apical half of fourth segment forming part of bulbosity. 

 Fifth segment constituting major and widest part of bulbosity, the 

 margin of the tergum produced over lateral margins of segments, 

 pointed beyond middle. Basal half of sixth segment forming part of 

 bulbosity (fig. 101). Seventh tergum as long as wide at apex, slightly 

 narrower basally than apically ; hind margin shallowly convex, with in-

 tending beyond median tubercle. Eighth tergum nearly semicircular,

 vated. Ninth tergum medianly slightly longer than eighth, lateral
