 inner margin, insinuate beyond cell and on submedian fold ; followed by a 

 diffuse dark cloud, which between veins 2 and 4 is much swollen and projects 

 towards hindmargin ; submarginal line pale, distinct, following the course of the 

 preceding shade, and therefore between 2 and 4 nearly touching margin ; a black
