31. Adults have dark brown forewings, irregularly streaked with heavy, sinuate , white to pale buff lines. 32. There is a rather sinuate series of small fuscous dots from the third costal spot to the tornus. 33. The medial line is sinuate , the distal half approaching the discoidal spot, then turning towards the dorsum. 34. There is a hardly perceptible faintly darker sinuate line from four-fifths of the costa to the tornus. 35. There is a pale ochreous terminal band of even width, sprinkled fuscous except along the sinuate anterior edge. 36. The antemedian line from the costal one-fourth is sinuated to one-third of the posterior margin. 37.
