with differently shaped frons, and narrower wings, with a different

 the ocelli ; antennal tubercle less prominent, yellow, black behind ; 

 ocellar tubercle only slightly prominent ; f rons clothed with short 

 pale hair; face and penstoma wholly reddish yellow, the facial 

 tubercle more prominent than in picta ; antennae and arista orange- 

 coloured ; the eyes do not seem to be banded. Occiput black,

pleurae paler above, darkened below like the pectus, with very 

 short hair. Squamula? yellowish, with a short golden fringe; 

 halteres yellowish. Abdomen proportionally shorter and broader, 

 the second segment being as long as the third : it is wholly reddish, 

 with indistinct black spots at the end of the second and on the 

 posterior corners of the third and fourth segments; hair on the 

 stalk pale and erect, on the rest dark and depressed. Legs includ- 

 ing the coxae wholly yellow, without any dark marking. Wings 

 distinctly less broad than \i\picta\ third vein sinuous as in picta, 

 and the seventh likewise, the anal cell therefore suddenly constricted 

 to a point before its end. The wings are blackish brown, but with 

 a broad and complete hyaline band, and besides with hyaline alula 

 and hyaline base of anal and axillary cells : the middle yellowish 

 spot is not a simple streak, but is more than double as broad, 

 extending to the small cross-vein and leaving a whitish spot in the 

 submarginal cell just above the bifurcation of the second and third 

 veins: apical isolated spot as in picta.
