 apices somewhat spatulate and divergent; seen from side the outer 

 clasper is curved upward at the beginning of its posterior third, in 

 almost a right angle, apex somewhat spatulate and recurved ; inner 

 clasper slender, outcurved apicall}^ (fig. 60) ; the aedeagus as seen 

 from above (fig. 61) with a median and two lateral branches, the 

 former considerably shorter than the latter, furcate at the tip, and 

 reinforced along the lower surface by two longitudinal strips ex- 

 tending nearly to the apex appearing as ribs on back of aedeagus 

 as seen from above; lateral processes becoming very slender apically 

 the terminal portion curved outward and then forward. Aedeagus
