with an acute anterior spine on each side and four tubercles 

 round the distal extremity. Anal sternite triangular, with two 

 very large tubercles on each side. Lateral surface of segments 

 very finely granular, much more coarsely so in front, the tracheal 

 tuberosities prominent ; the inferior keel strong on the anterior 

 segments, but gradually dying out towards the hinder end of 

 the body, just visible on the seventeenth ; even on the fourth 

 segment it is represented by a flattened excrescence, projecting 

 behind the posterior stigma. 



Sterna normal, not spined, that of the eighth with a long 

 linguiform process directed downwards and a little forwards. 



Legs longish, hairy ; femur longer than the tarsus, about 

 twice as long as trochanter, but not twice as long as the tibia, 

 which is only a little shorter than the tarsus ; a tuft of white 

 hairs on the apex of the lower surface of the trochanter, and 

 the last two segments thickly clothed beneath with white 

 hairs ; claw conspicuous. 



Copulatory feet long, slender, the terminal portion bent 

 strongly downwards, terminating in an external short, truncate, 

 spatulate piece, with the flagellum and its sheath rising on 

 the inner side of this, both being strongly curved and 

 directed inwards, downwards, and outwards ; the flagellum 

 simple, the sheath apically bifid, with two short processes 

 near its base. 



Length 44 millim. ; width across keels 5, width between 

 the keels 3*5. 



Loc. A single male example from Chusan Island [J. J. 

 Walker).

$ . — Colour black or very deep brown, the posterior half of 

 each tergite with a yellow transverse band, which (except on 

 the first four segments) spreads on to the posterior half of 

 the keel ; antennse black ; legs black distally. 



Body nearly smooth, polished, finely striolate above, the 

 first tergite subgranular ; keels very small, situated above the 

 middle of the sides, defined above by a sulcus, without distinct 

 anterior and posterior angles ; that of the second segment 

 below the level of those of the first and third, with its anterior 

 angle strongly produced ; almost absent on the nineteenth ; the 

 transverse sulcus beginning on the fifth and extending to the
