of a small portion of the uncus at the tip and a small part close

Segment nine, although retracted, is similarly perfect as are also its 

 rods. Just within the left rod is the ostium bursae with its guard-flap, 

 and leading away from it in a complete state are the ductus bursae and 

 the bursa itself which is decorated internally with a signum of ordinary 

 type. 



Placed one on each side of the left inner rod are to be noted the 

 pupal tubercles.

On the right, half in the 7th segment and half in the 6th, are the

 perfection of the female organs, unable to secure exit. 



In spite of their density and entangled character they can be made 

 out to be two distinct structures.
