Modified segments. -( $ ). The manubrium of the claspers is straight 

 and narrow, while the process extends upward as a short, blunt cone, 

 where at the tip there are several fine hairs. The lower margin is 

 evenly and gently rounded. The finger is short, extending but a 

 little above the process. It is concave on its anterior surface and 

 convex on its posterior, and from the posterior margin there are 2 

 large and 2 small bristles alternating. Two long heavy bristles arise 

 from the process below the insertion of the finger. The ninth ster- 

 nite is broad, with a deep sinus in its posterior border. Its lateral 

 surface contains numerous fine hairs, these hairs being somewhat 

 larger just beneath the sinus. Along the dorsal border of the tenth 

 sternite there are 3 heavy bristles in line. At the tip of the tenth 

 tergite there is one heavy bristle. Besides these heavy bristles in 

 this segment there are numerous fine hairs. 



( 9 ) The eighth tergite contains just anterior to the sensory plate 

 about 12 small hairs while just beneath the sensory plate there are 2 

 long bristles. Lower down there is a patch of about 6 bristles and 

 on the apical margin 4 to 6. The stylet is short, cylindrical, slightly 

 larger at the base than at the tip, where there is a long bristle. On 

 the under surface arises a fine hair. Substylar flap (tenth sternite) 

 has along its margin numerous hairs.
