Clay-yellow, the pile on head, thorax, and feet yellowish; the 

 bristles yellow or yellowish-brown, according to the light in which 

 they are seen ; the pile on the abdomen yellowish at the basis 

 only, black elsewhere. Front of a more vivid yellow, rather 

 broad, with long bristles, the eyes rather large, oval; cheeks of a 

 medium breadth. The face rather retreating, somewhat excavated 

 under the antennae; the anterior edge of the mouth not projecting 

 in the profile. Antennas yellow, of medium length ; the third 

 joint with a rounded anterior corner ; the rather long arista is 

 much incrassated at its extreme basis, otherwise very thin and 

 bare. Oral opening rather large, rounded ; palpi and proboscis 

 not projecting beyond it; the latter not geniculated. The middle 

 of the upper side of the thorax seems to have borne only two pairs 

 of bristles. The very moderately convex scutellum bears four 

 bristles. Scutellum and abdomen are more shining than the 

 thoracic dorsum, which is opaque in consequence of a yellowish 

 pollen ; abdomen without any picture. Wings rather long and 

 of nearly equal breadth ; the third longitudinal vein distinctly 

 bristly for a considerable portion of its length; crossveins straight 

 and steep; small crossvein a little beyond the middle of the discal 

 cell. The picture of the wings is a very peculiar one; its prin- 

 cipal feature consists of three very conspicuous brownish-black 

 spots ; the smallest among them has the shape of an oblique, 

 somewhat irregular half-crossband; with its anterior end it covers 

 the tip of the stigma, with its posterior end it covers the small 

 crossvein and suddenly stops near the fourth vein ; the second 

 spot, which covers the posterior crossvein, has a square shape, is
