extremity of terminal joint dark brown, terminal joint elongate 

 and tapering, with a prominent ridge on upper side at base, 

 branched hairs numerous, twenty-two to twenty-eight in number • 

 2)alpi cream-buff, yellowish smoke-grey above, slate-grey or dark 

 greyish-brown at tips ; jirohosris hulb dark mummy-brown or 

 clove-brown, raw-umber-coloured on each side, except as a rule at 

 distal extremity. 



Thorax. — Pleurae and pectus grey, mouse-grey, or dark grey 

 in $ , paler (smoke-grey or drab-grey) in ? ; scutellum cream- 

 buff, upper surface with a well marked dark brown blotch,

 bristles long in both sexes. 



Abdomen. — Dorsum of second segment with a dark brown 

 blotch on each side (sometimes indistinct or wanting), not 

 extending to lateral or hind margins ; dark hands on third to 

 sixth segments inclusive very deep [i.e. on each segment the dark 

 band, starting from front border, extends close to hind margin, 

 thus confining the ground colour, apart from the median inter- 

 space, to a very narrow hind border) ; each half of each dark 

 hand, when fully developed, is eiit off squarely at the median 

 interruption, but in many specimens the inner extremities of the 

 bands on the third and fourth segments are partially obliterated ; 

 posterior angles of second to sixth segments inclusive cream- 

 coloured ; seventh segment smoke-grey or drab-grey ; hypopygium 

 of cJ ochraceous-butf, broadly oval in outline as seen from below. 



Legs. — Inner surfaces of front femora, and usually also outer 

 surfaces of middle and hind femora towards distal extremities 

 more or less grey or greyish; middle femora sometimes with a 

 mouse-grey streak on lower part of outer side, and middle and 

 hind femora each with the usual elongate dark brown mark on 

 under side near distal extremity. 



Wings light drab-coloured, unicolorous. Squamae waxen 

 white, with cream-coloured border. Halteres cream-coloured.
