Rostrum reddish. Palpi black. Antennae with the scape reddish 

 yellow, the flagellum black. Head grayish brown, the vertex narrow. 

 Mesonotum dark brown with a sparse brownish yellow pollen and 

 without distinct stripes. Pleura clear gray becoming more yellowish 

 below. Halteres pale. Legs with the coxae brownish yellow, the an-

 gray tinge, highly iridescent ; veins dark brown. Venation : Sc mod- 

 erately elongated, extending to about midlength of the basal deflection 

 of R4+Sy R^ moderately elongated, about as long as the long cell 

 1st M2 and half again as long as the deflection of /?4+5; basal de- 

 flection of Cui inserted at or before one-third the length of cell 1st M2. 

 Abdominal tergites dark brown, the apical third of each segment 

 more yellowish, producing a banded or tigrine appearance ; segment

This species is apparently close to D. nigripes O. S. in the
