cate the relation of the species. The size and shape of the 
radial cell seem to give good specific characters and it is best 
studied of course in balsam mounts, but a two-thirds objective 
and ocular micrometer will serve the purpose on well mounted 
pinned specimens. As here used the “‘radial cell ratio’ is 
the length of the radial cell divided by the width (inside 
measurements) and the “‘cell to wing ratio’’ is the maximum 
width of the front wing divided by the greatest width of the 
radial cell.
