In some specimens there are two elongate spots on the fold, but 

 such markings are so little differentiated from the ground-color as to 

 be scarcely worthy of description. The whole insect has a plain 

 unornamented appearance, it is somewhat darker and grayer than 

 conia, from which it differs in having veins 3 and 4 of the hindwings 

 stalked instead of connate.
