dark marginal seam in cells R2 and R3; narrow brown seams
along cord and outer end of cell 1st M2; a small oval spot at
end of vein 2d A; vein 1st A unmarked or virtually so; veins
yellow, darker in clouded areas. Venation: Sc long, Sc1 ending
nearly opposite midlength of Rs; m-cu shortly before fork of M.
Abdominal tergites dark brown, caudal borders of segments
