Halteres yellowish-white. Wings with three brownish-black bands; the veins are black upon these bands, but ochre-yellow elsewhere, which gives the whole basal part of the wing an ochre-yellowish tinge. The first band begins at the costa with a short black stigma, is perpendicular and rather dark, as far as the fourth longitudinal vein and even beyond; the remainder of the band, as far as the posterior margin of the wing, is usually very faint; the small crossvein is a little beyond the margin of this band; the second band runs over the posterior crossvein and is perpendicular and rather broad; its posterior end is very pale; with the third band it is generally connected only by a dark border along the costa; sometimes, however, this border becomes broader and extends in some specimens as far as the second longitudinal vein. The third band, running along the apex, is likewise rather broad, extends as far as the fourth longitudinal vein, and even beyond it, in the shape of a gray shadow. The last section of the fourth longitudinal vein, beyond its middle, converges towards the third; near its tip, however, this convergency becomes again much less. Mob.
