and covered with hafts similar to those on the thorax, and on the 

 postero-outer margin there is a long whitish tuft of soft hairs, the 

 similar but shorter and less conspicuous one on about the upper wing- 

 base. Pleurae densely clothed with a yellowish grey dust and bearing 





 numerous not very long rather inconspicuous whitish yellow hairs 



which are almost entirely replaced by numerous longer conspicuous 

 black hairs on the postero- upper half; prothorax and pteropleurae 

 covered with abundant more longer very pale brownish yellow soft 

 rather shaggy hairs ; on the postero-upper margins of the meso- and 

 meta-pletirae there is a long dense conspicuous tuft of very pale yel- 

 lowish grey soft hairs. Sctitellum as the thorax, but the black and 

 yellow pubescence both more numerous and about the margin with a 

 dense rather depressed yellowish pubescence. 



Wings clear with the costal cell and stigma pale yellowish but 

 the latter sometimes very slightly tinged with yellowish ; posterior 

 cells all widely open excepting of the first one which is contracting 

 towards the margin, discal cell moderately large and apparently longer 

 than the first posterior cell, and the anal cell closed with a long 

 petiole ; the upper branch of the cubital fork with the distinct recurrent 

 veinlet. Squamae in the alar pair grey with a conspicuous black brown 

 margin and a dense brown yellowish grey fringe (which is quite whitish 

 grey when seen from a certain direction) except for a long yellowish 

 tuft about the angle ; in the thoracal pair yellowish with a broad brown 

 or reddish brown margin and a brownish fringe of more fine hairs. 

 Halteres blackish brown, with the extreme tip of the knob grey, and 

 with the stalk more or less paler. 



Legs blackish, with the coxae and femora densely dusted with 

 yellowish grey, and with the basal half or more of the front tibia- 

 and the almost entire of the last two tibiae pale brownish yellow ; 

 front coxae covered with a long pale grey soft pubescence, and near 

 the top there are some short black bristly hairs; front femora at the 

 extreme apex yellowish, with the shining castaneous black broad
