Head and thorax chestnut-brownish or reddish chestnut-brown ; 

 thoracic dorsum sometimes darker brown ; abdomen always black 

 or brownish-black. Front opaque, usually more ferruginous-red 

 than orange-red, sometimes darker, with a very narrow border of 

 white pollen along the orbits ; this border also extends over the 

 face, but although broader here, it is less distinct, or at least 

 more perceptible only a little distance below the antennae. The 

 remainder of the face is a little pollinose in the vicinity of the 

 antennae only. The third antennal joint is usually strongly in- 

 fuscated, with the exception of its basis. Thoracic dorsum with a 

 grayish-white pollen, which does not form any distinct stripes, 

 while the ground color of the broad intermediate stripe is often 

 darker than its surroundings, so that it becomes distinctly visible. 

 Feet yellowish-brown, tarsi strongly infuscated towards their tip. 

 Halteres whitish-yellow. Wings comparatively large and broad 

 with a rather strongly projecting posterior angle, and a rather 

 narrow alula ; at the anterior margin there is an excision, which 

 is very conspicuous, although it forms only an obtuse angle ; it is
