being in one of the specinaens another bristle lower down. The 

 vertical arm of the ninth sternite (IX, st.) is very slender, especi- 

 ally the upper portion, which lies at the manubrium of the 

 clasper. The ventral arm is divided by a ventral sinus into a 

 longer proximal portion and a shorter and broader distal poi'tion, 

 the latter being about as long as it is broad. The proximal 

 portion bears at the ventral margin 5 or 6 bristles, the two distal 

 ones of which stand close together one on each side, and are fairly 

 stout in comparison with their length. — $ . The seventh sternite

(text-fig, 113, VII, st,) narrows in side-view; its apex is truncate, 

 somewhat obliquely, and slightly emarginate, with the upper 

 apical angle quite distinct, The eighth tergite bears 8 to 10 

 small bristles above the stigma, 2 or 3 long ones beneath the 

 stigma besides some small ones, and there are about 12 long 

 bristles and 10 to J 2 shorter ones on the lower half of the segment. 

 The stylet is twice and one-half as long as broad. The bristles 

 on the ninth and tenth tergites (which segments are separated by 

 a distinct suture) are numerous. The receptaculum seminis is 

 distinguished by the head being neai-ly three times as wide as the 

 tail and only half its length, It has been disturbed in its position 

 by the mounting in both specimens which we have, and the out- 

 line we give does not exactly represent a true lateral aspect of the 

 organ.
