angle. The mannbrinm is loner and has a ronnded apex. The internal arm of 

 the elbowed ninth sternite (text-tig. 43, IX. st.) is broad. Its dilated apical 

 portion is ronnded on the distal side, while its pro.ximal npper angle is acute, 

 and produced obliquely upward. The horizontal arm is widest in the centre, 

 nearly straight above, almost evenly ronnded beneath, and bears on the ventral 

 margin three long bristles, of which the proximal one is large and curves distad, 



while the other two are thin and point ventrad. ?. The seventh abdominal 



sternite (text-tig. 44) has a broad but shallow sinus which diminishes ventrally, 

 the lobe placed above the sinus being very strongly rounded and projecting more 

 than the ventral portion of the segment. The apes of the eighth tergite is truncate- 

 rotundate and bears eight or nine bristles at and near the edge on the inner and 

 outer surfaces together, there being farther proximally on the segment eight or nine 

 more bristles, as shown in the figure (text-fig. 44, VIII. t.). The sensory plate is 

 rather strongly convex. The anal tergite is transversely raised at the base and bears 

 on this elevated j)ortion a row of bristles, another set of bristles placed near the 

 apex of the segment, but none in between the two sets. At the angle below the 

 base of the stylet there is one bristle. The stylet is straight, conical, three times as 

 long as it is broad at the base, and bears two minute bristles at a short distance 

 from the long apical one. The anal sternite has ten bristles, of which one or two 

 are stout. The recejitaculum semiuis has a large, irregularly-shaped head, which is 

 nearly as broad as it is long, its aperture being ventral (as in Ctenophthalmus), not 

 terminal. The tail is about as long as its head.
