Male. Frons somewhat broader than high, black, slightly greyish; 

 bristles very strong, inner bristle of lower row slightly below the outer 

 and nearer to it than to the upper supraantennal ; supraantennal 

 bristles unequal, the lower pair small, not half as large as the upper; 

 the upper supraantennals very close-standing, much more approximate 

 than the inner bristles of middle row, the lower still a little more 

 approximate. Antennæ somewhat small, black, arista somewhat 

 long, distinctly pubescent. Palpi yellow, dusky towards the base; 

 they are somewhat narrow, with ordinary bristles. Thorax reddish 

 or brownish red, darkest above, palest on the humeri; it is almost 

 dull, with blackish brown pubescence. Pleura reddish with some 

 darkenings. Mesopleura bare. Abdomen robust, yellowish red, dull, 

 first segment like the postnotum greyish; the short hairs are distinct 

 and slightly longer at the hind margins of the segments. Hypo- 

 pygium quite small and withdrawn so that only the lower part is 

 seen, which is blackish grey and has fine hairs; ventral plate yellow, 

 rounded; anal tube small, yellow. Legs yellow, tarsi a little more 

 brownish; hind femora rather broad, the hairs below the basal part 

 distinct, but not long; bristles on hind tibiæ very small and 

 numerous. Wings brown, veins brownish yellow, strong; costa thick,

 sions about as 18 — 11 — 6, thus 1 about equal to 2 + 3 and 2 about 

 double 3; fork a little longish; costal ciha moderately long; fourth 

 vein a little S-like at the base and curved in its first part, for the rest 

 quite straight. Halteres pale yellow.
