crescent and extends from after the basal cross-band in the anal cell 

 to the actual end of the axillary vein ; along the apical margin of the 

 axillary cell an inconspicuous narrow marginal band from the apical 

 angle of the cell to the middle of the margin between the end of the 

 anal vein and the end of the axillary vein. Squamae pale greyish 

 yellow with the very short inconspicuous whitish fringes ; halteres pale 

 yellow with the blackish knob which has a narrow yellowish margin. 



Legs not uniform in colour, mostly more or less brown or dark 

 brown, moderately pubescent, witli the typical rings on the middle 

 tibiae only, and all tibiae more or less white near the base ; front 

 coxae moderately dilated about the middle, yellowish brown but some-

 white pubescence which becomes longer and denser about the basal 

 half (especially on the anterior side) like that in the prothorax ; front 

 femora brown but slightly covered with a greyish tomentum, becoming 

 darker apically, slightly curved twice (first above and next below),, 

 bearing a depressed rather short blackish pubescence which becomes 

 less slopy and longer outside and which is mostly replaced by greyish 

 hairs about the outside of the basal half, on the lower margin of about 

 the apical one-third there are two conspicuous fringes of the sloping 

 stout blackish hairs, of which the interior fringe more conspicuous and 

 longer ; front tibiae dark brown with a greyish band about the basal 

 one- third and this band is not well-defined, compressed laterally, with 

 a short depressed numerous blackish pubescence all over which becomes 

 slightly longer outside, and about the lower apical end there are a very 

 few long pale touch-hairs ; front tarsi uniformly dull black, bearing the 

 rather conspicuous long pale touch-hairs ; middle femora pale yellowish 

 brown, slightly dusted with grey outside, and becoming a little darker 

 towards the apex, bearing a fine whitish pubescence which becomes 

 longer outside and which is intermixed with a very few short but stout
