244 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 5 



Charles Island ; 1934 ; H. Wittmer. 1 c? 2? 



Determination checked by comparison with the type c? and type $, 

 which are the only other known specimens. 



Male genitalia: (pi. 31, figs. 1-2) The seeming differences be- 

 tween the 2 valves are due to slight differences in the angle of mounting. 

 The large central structure is the anellus ( juxta) which forms a complete 

 arch over the aedoeagus. Aedoeagus with microtrichiae as indicated by 

 stipple. 



Female genitalia: (pi. 31, fig. 3) The median part of segment 

 VII is the sternite beneath the base of which the ductus bursae opens; the 

 ostial pouch is additionally supported to the apex of segment VII by 

 lateral walls, as shown in figure. Ductus bursae with 2 supporting 

 sclerites, as shown. Bursa copulatrix evenly covered with minute micro- 

 trichiae.
