 cal vein clouded ; the discal cell in sometimes bearing a fine pale spot 

 in the middle ; anal cell usually closed at the margin but in sometimes 

 fairly conspicuously open ; the upper branch of the cubital fork about the

 a yellowish margin, but in the alar pair the margin is blackish and 

 bears a short conspicuous black fringe.
