Pale, marked with brown; vertex with a median brown spot behind; face 

 with three small dark spots, nose faintly lineate, the dark forming a large spot

 There are small dark clouds in many of the cells, and larger marks at the anal 

 angle and just before the discal cell. The stigma is fully twice as long as

 one point, its outer side concave.
