 pale brown, whiter toward the base, the spaces between the 

 nervures dusted with white ; part of the costa faintly dotted 

 with the same, and followed by an extremely narrow white 

 line edging the curve nearly to the apex ; before the middle 

 of the wiug is a faint brown dot, and another with some
