pile yellow. Legs yellow, tarsi darker. Wings tinged with 

 3^ellow, the anterior veins darker. Halteres yellow, the knob 

 dusky at base. 



An examination of the type shows that the antennae are short, 

 the intermediate joints being but little longer than wide; that 

 the cubitus forks far proximad of the crossvein and that the 

 anal vein ends slightly distad of the R-M crossvein. "Middle

 mented ; hypopygium inflected under the abdomen. Legs stout, 

 fore legs short. Wing oblong-oval ; costa produced far beyond 

 the tip of the radial sector; subcosta rather short, ending in 

 Ri; the radial sector arises near the middle of the wing; petiole 

 of the media long; cubitus forks proximad of the proximal

 tion ; anal veins vestigial. (Fig. 216). Resembles Docosia but

 brownish, especially anteriorly. Setse of the lateral and anterior 

 margins of the thorax rather conspicuous ; about 5 pairs of 

 scutellar setse, the longest about as long as the tibial spurs. 

 Abdomen brownish yellow, appearing darker than the thorax 

 because of the presence of black setulse ; apically somewhat 

 darker ; hypopygium as figured on Plate 7, Fig. 5 in Genera
