middle part of the margin than towards tlic sides, and in 

 tergites 4, 5, and G tlicsc median ones become very long; on 

 tergitc 5 the marginal series is narrowly, and on tergite 6 

 Avidely, interrupted in the middle, but on the other tergites 

 it is contimious. Anal segment tapering considerably, with 

 sides slightly curved towards the apex, with short erect 

 bristles on the posterior part of its surface and at the sides, 

 and two moderately long ones at either hind angle. 



Basal sternite with a slightly impressed middle line, sur- 

 face fairly closely covered with bristles ; etenidium close, 

 slightly sinuate in the middle. Slerniies 2 and 3 have their 

 hind margins set with moderatel}' long bristles of slightly 

 varying lengths, those at the sides rather longer than those 

 in the middle; sternite 2 has two irregular series of very 

 short bristles across its disc, and some longer suberect 

 bristles at the sides of the disc ; sternite 3 has one irregular 

 transverse series, some of the lateral bristles of which are 

 considerably longer and suberect. Sternite 4 lon^^i:!' • hind 

 margin curved, bearing in the middle about 10 short, stout, 

 thorn-like bristles ; on either side of these are bristles 

 of varying length, those at the sichs being longer, and 

 immediately iu front of these marginal bristles are suberect 

 bristles of varying length; across the posterior part of the 

 disc is a very irregular series of rather short bristles, of 

 which the median ones are nearer the hind margin than the 

 lateral ones. Anal segment with rather numerous erect and 

 suberect bristles at the sides ; claspers nearly parallel, not 

 contiguous, curved only in the dorso-ventral plane towards 

 the apex, tapering, each with two bristles directed outwards 

 in its median third, and other bristles directed inwards in its 

 basal third. 



? ABDOMEN (PI. X. figs. 3, 4). — Busul tergite of much 

 the same form as in c? , but with the five bristles at either 

 hind angle longer and stouter, Tergite 2 long, of remark- 

 able form ; subeordate, narrowed behind, each side being 

 convexly curved in its anterior part and eoncavely sinuate in 

 the narrower posterior part of the tergite; it is divided into 

 two halves by a median longitudinal line of pale membrane, 

 each half having an obliquely truncate hind margin bearing 

 4 or 5 long, stout, dark bristles, erect and directed outwards, 

 immediately in front of them being a series of very short 

 dark thorn-bristles ; on the disc of the segment, at about 

 ^ its length from the hind margin, each half i^ears an 

 irregular, oblique, transverse series of very short dark 

 bristles ; there are scattered very short bristles near the 

 anterior angles of the tergite, and a few very minute ones
