tunately lost, but luckily this did not occur till after it 

 had been closely examined, and figured. 



Although the femora and tibias are not very broad, and 

 the $ has a very short anal segment, yet it does not seem 

 possible to place this species in any subgenus but 

 Lidropodia. 



Head with short bristles along the cheek-margins, and with a few 

 at the front margin of the crown : otherwise bare. Thorax dorsally 

 with a curved row of bristles on either side. Thorax ventrally 

 very slightly broader than long, fiat, with the portions anterior to 

 the oblique lines sloping upwards somewhat : middle line red- 

 brown, imjJressed posteriorly, and also slightly anteriorly : surface 

 as usual bearing fine bristles, with some longer ones at the hind 

 margin, of which two are very long. Femora and tibise (Fig. 

 14) not very broad : greatest breadth of femur = only a little over 

 J its length ; that of the tibiae = \ its length. Femora and tibise 

 of the 9 slightly broader than those of the ^ . Tibite with the 

 usual 3 cross-rows of bristles on their lower side distally. 



Abdomen op the i^. (Figs. 15 and 16). — Long and narrow. Ex- 

 cluding the anal segment, 5 dorsal segments (tergites) are visible : the 

 first is really composed of 2, but the small basal one is not very sharply 

 delineated, and is hard to see ; this compound tergite is here reckoned 

 as No. 1 (Fig. 15a.) Tergites 1, 2, with short bristles over tlieir sur- 

 faces, long ones on their hind margins. Tenfite 3 with a few rather 

 longer bristles on the surface, long bristles on its hind margin. Tergites 

 4, 5 bare on the surface, their hind margins set with short stiff spines, 

 between every 2 or 3 of which are long bristles, 2 near the middle 

 of tergite 5 being very long. Anal segment viewed from above 

 remarkably short, only about J as long as broad : hind margin not 

 rectilineally truncate, but forming a slightly concave curve : dorsal 

 surface bare, sides and hind angles bearing strong bristles. 



Basal sternite without median impression, bearing fine bristles not 

 very close : ctenidium well-developed, its margin scarcely sinuate. 

 Of sternites 2, 3, 4, no, 3 is longest ; nos. 2 and 3 have a few short 

 bristles on the surface, no. 4 is almost bare : their hind margins 

 bear bristles of very varying length, not very close, some (especially 

 at the sides) being very long and strong. Anal segment ventrally 

 much longer than dorsally, its length nearly = its breadth at the 

 base, its apical breadth = a little over ^ its basal breadth : surface 

 bare, except for two divergent rows of bristles, one on either side, 

 commencing at the edge of the cavity in which the claspers lie, and 

 running outwards and backwards from near the apex of this cavity 

 to the side of the segment. Claspers narrow, rather short, with
