The distribution of the ashy white scaling varies considerably, 

 and in some specimens occupies a much larger proportion of the 

 wing-surface than in others. It appears to be more variable than 

 the larger, and perhaps allied, cicadella Z., and is paler and less 

 uniform in its ill-defined marking than arachnodes.
