together. Thorax : pleurae, pectu<=i, and anterior border of 

 dorsum smoke-grey ; dorsudi clothed with short, deciduous, 

 shining, pale yellow hairs, pleurge clothed mairdy with 

 yello-wish-white hair, prse ilar c illi cloihed below with blackish- 

 brown hair; scutellum raouse-giey, with a dark olive-brown 

 blotch on each side of middle line. Abdomen : olive-grey 

 border of dorsum somewhat olive-brown on sides of distal 

 half and at tip, median line usually more or less distinctly 

 marked with mouse-grey, hind b )rders of segments smok"- 

 grey to mouse-grey on basal, light olive-ljrown on distal 

 half ; dorsum clothed with short pale yellow hair on grey 

 borders, in centre of first segment, and on hind margins of 

 all segments, and with brownish hair on dark brown area ; 

 venter uniform smoke-grey, clothed with whitish-yellow hair. 

 Wings pale brown, light markings of usual type but rather 

 coarse, and often running together in such a way as to 

 produce a very confused pattern, markings extending 

 througliout whole area from base of basal cells and axillary 

 incision to end of second longitudinal vein ; stigma light 

 brown, not sharply marked, but with a distinct quadrate 

 brown patch below it extending to third vein, and there 

 sending off a narrower process which reaches fourth vein 

 where it forms upper boundary of distal half of discal cell ; 

 distal portion of marginal cell beyond stigma often almost 

 entirely pale ; each end of discal cell often occupied by a 

 more or less comi)lete pale loop, separated by a brown band 

 across centre of cell, and each with a centre of dark ground- 

 colour ; the three usual rosettes generally more or less 

 distinct, but sometimes partly obliterated owing to fusion of 

 markings ; sinuous V-shaped mark beyond fork of third 

 vein usually distinct; along posterior margin of wing a 

 row of light markings often, but not always, present in 

 distal angles of some or all jjostcrior cells ; basal cells each 

 with a more or less complete pale loop at each end; anal 

 angle with a more or less complete broad pale border, one 

 extremity of which runs inwartls, as usual, across anal cell, 

 while the other ends in the usual loop in angle formed by 

 axillary incision and sixth longitudinal vein. Halteres stniw- 

 yellow, knob brown above and below. Legs : coxje and 

 femora mouse-grey, tibia) oehraceous buff, with brown rings ; 

 front tibiie brownish at extreme base, dark bown at tip, and 

 with a brownish band below middle, partly in contact with 

 dark brown tip ; middle and hind tibiie with three brown 

 bands, situate respectively at base, apex, and in midillc ; 

 front tarsi dark brown, basal half or two-thirds of tirst joint
