Wings and squamae as in the female, but the halteres almost 

 Mways pale orange with the knob not darker. 



Legs mainly orange, but blackish on the coxae, on nearly the 

 basal half of the front femora, on quite the basal half of the middle 

 pair, on more than the basal half of the hind femora, on about the 

 apical half of the front tibiae, and on the tip of the posterior tarsi 

 (begining to darken soon after the basal joint), while the front tarsi 

 are deep black ; trochanters brownish ; the blackish part on the femora 

 and on the .posterior tibiae very often disappear, and in such a specimen 

 the trochanters are usually orange in stead of brownish and the front 

 tibiae are blackish only on the apical one-third; these dark portions 

 are not well-defined. Pubescence on the front coxae greyish yellow, 

 considerably long and shaggy, but slightly becomes short and sparse 

 at the apex ; the front femora with long and somewhat dense greyish 

 yellow pubescence about the base of the outerside, which becomes black- 

 ish about the top, and the bare subfemoral space rather narrow (though 

 broader than in the female) not furrowed and somewhat inconspicuous 

 with an inconspicuous fringe of minute black bristles on its inner 

 margin ; front tibiae with a few black hairs on the upper-outer margin, 

 but otherwise covered almost all over with short depressed black bristles, 

 and there are very few scattered touch-hairs near its tip and on the 

 front tarsi which are clothed with depressed tiny black pubescence all 

 over ; pubescence on the lower and outer sides of the middle femora 

 longer and denser than in the front femora, greyish yellow ; middle 

 tibiae with a slight fringe of longer black and yellowish hairs on the 

 upper-outer part and with small depressed black bristles more scattered 

 and with still smaller glistening yellowish ones intermixed, the spurs 

 with black tip and more slender than in the female ; pubescence on 

 the outerside of the hind femora less dense but longer and more 

 extended to the underside, and with only a few black bristles about 

 tlie tip of the upper side ; hind tibiae with a conspicuous even black 

 dorsal fringe, and the underside with a shorter finer mainly pale ciliation
