well-defined, reaching to the inner margin but on the postical cell with 

 a deep incision from the inner border, the clear portion usually ex- 

 tending to the fourth posterior cell, and very often both the centre 

 of the discal cell and the base of the submarginal cell somewhat paler, 

 especially distinct on the former ; the inner margin of the cross-band 

 conspicuously angulatecl at the point of the basal angle of the postical 

 cell and then reaching to the end of the lower branch of the postical 

 fork ; the outer margin of the cross-band nearly straight or sometimes 

 slightly curved inwards from the apical end of the stigma to the open 

 end of the fourth posterior cell ; upper branch of the cubital fork with- 

 out a recurrent veinlet near the base but sometimes obtusely angulated ; 

 fourth posterior cell open but distinctly contracted at the margin ; anal 

 cell distinctly closed just before or at the margin. Squamae yellowish 

 brown or brown with brown* or blackish brown margins and bearing 

 very inconspicuous fringes, but at the angle with rather dense yellowish 

 fringe ; halteres blackish brown, with the paler stalk, slightly shining 

 but moderately obscured by a grey dust. 



Legs yellowish brown excepting of the anterior trochantcr, middle 

 and hind coxae, and hind femora brown or dark brown and slightly 

 shining ; fore coxae about two- thirds the length of the fore femora, 

 slightly tinged with brownish towards the base, bearing a few, short, 

 yellowish hairs ; fore femora covered with fine yellowish pubescence 

 but at the outer side a few somewhat long and stout black hairs 

 intermixed ; fore tibiae slightly dilated and moderately curved, .slightly 

 darker and distinctly shorter than the femora, with numerous very 

 short blackish hairs not intermixed with any others ; middle legs paler 

 than the others, the pubescence as in the fore legs but the black hairs 

 on the femora much sparser, the tibiae bearing two subequal rather 

 stout black apical spurs ; hind femora at the apex only yellowish brown 

 or reddish brown, bearing very short blackish pubescence, but on the 

 lower surface with yellowish hairs ; hind tibiae much longer than the 

 femora, slightly darker than the tarsi, with almost entirely blackish
