resembles the preceding sternite, but is longest ventrally as shown in the 

 figure (Fig. i, viii. st.), and bears on each side only one long bristle, which is 

 accompanied by a few hairs. The clasper (Fig. i, CI.) is not separated by a 

 suture from the internal portion of the ninth tergite, and this internal portion 

 of that segment is produced into a kind of manubrium. The manubrium of 

 the clasper itself terminates in a slender point. The dorsal posterior portion 

 of the clasper forms a broad process (P), which is about as long as it is wide. 

 The moveable process (F) is almost shaped like a thumb in side view, the 

 distal margin being much more strongly rounded than the proximal margin. 

 The distal margin bears one slender bristle at one-third or one-fourth from the 

 base and a much longer one beyond the centre or at two-thirds, besides a 

 number of short ones as indicated in the figure. In the second c? the " finger " 

 is more rounded at the apex than in the one figured. There is only one long 

 bristle at the edge of the clasper below the insertion of the finger and several 

 small hairs. The ninth sternite (Fig. i, ix. st.) is exceedingly slender, the 

 vertical arm as well as the horizontal one, excepting the apex of the vertical 

 arm. The distal half of the horizontal arm is about twice the width of the 

 proximal half, and its peculiar shape reminds one a little of a rocking horse 

 reversed. This portion of the sternite is elbowed beyond the centre, the apical 

 two-fifths being curved downwards and bearing at the proximal ventral corner 

 on each side two long bristles, which are evenly curved and are accompanied 

 by two more, which are short and spine-like in shape. The tip of the sternite 

 is truncate, the apical portion being triangular and bearing along the upper 

 edge a row of hairs on the outer side and two hairs on the inner side, and at 

 the ventral angle one short spine-like bristle on the inner side. The tenth 

 tergite is distinctly separated from the ninth by a suture, which is situated at 

 some distance from the sensory plate. The tenth tergite bears about 6 short 

 hairs on each side and a row of short bristles along the apical edge. — ? . The 

 apex of the seventh abdominal sternite is very slightly incurved twice (Fig. 2). 

 The eighth tergite bears 5 to 7 short hairs above the stigma, and one or two 

 long bristles, accompanied by one or two small hairs below the stigma. The 

 apical margin is rounded and slightly undulate, with the lower angle projecting 

 (Fig. 2). There are only 8 or 9 bristles on the outer side of the lower half of 

 the eighth tergite and 4 on the inner side. The bristle at the tip of the stylet 

 is much shorter than the bristles of the posterior row on the sixth tergite, but 

 longer and thicker than the longest bristle of the anal sternite. This latter 

 sternite bears ventrally in the centre, where it is slightly elbowed, a cluster of 

 short, thick, spine-like bristles, which are separated from the subapical
