 around the black bristle ; scutellum yellow medially, brown laterad of the 

 bristle , postscutum brown ; metanotum broivn ; sterna yellow ; epiniera 

 and episterna reddish brown, forming a narrow longitudinal band. 



Halteres pale brown, subapically darker brown ; tip yellow. . Legs 

 short and stout, thickly covered with appressed hairs ; coxfe short, cylin- 

 drical, in the fore leg about as long as the trochanter ; in the middle leg 

 shorter than the prominent trochanter ; in the hind leg prominent, much 

 exceeding the shorter and narrower trochanter. Femora rather short, 

 slender proximally, soon thickening so as to become almost clavate 

 distally ; the fore femora have stout, long hairs, which are scattered 

 irregularly amongst the appressed hairs, becoming very numerous near the 

 apical portion of the lower surface of the segment. Tibia; slender through- 

 out, tibia; and metatarsi with a few prominent hairs regularly disposed ; 

 the other tarsal segments with a single hair at the tip. The fore femora 

 are as long as the succeeding segments combined ; the hind legs are longer 

 than the others. Fore legs lacking (in the holotype) ; middle leg, coxte 

 and trochanter light yellow ; femora yellow, with a medial and subapical 

 brown band ; tibije yellow, with a dark band before the middle and at the

Abdomen with numerous scattered hairs, yellow ; the apical margins 

 of the segments brown. 



Wings with a faint yellow tinge ; costal border and radial veins 

 yellow; remaining veins darker; a dark suffusion around cross-vein i-m, 

 at the union of M3 with Mj,., and along the basal deflection of Cu,.
