There is only one difference between our form and the European 

 antiquana: a few more short spines (8-12) on the inner side of uncus 

 at apical margin. In the European specimens before me they num- 

 ber 4 to 6 ; but I doubt very much if the character is constant. None 

 of our American specimens, however, show so few. For this reason 

 I am keeping nubilana as a racial designation. There is no difference 

 in female genitalia. Walsingham's vetulana is smaller than most 

 western nuhilana^ but the same size as typical eastern specimens. A 

 cotype of the former is in the National Collection. Our variety, as 

 well as the European, shows considerable variation in color, and dif- 

 ferent American specimens from any given locality vary consider- 

 ably more in size. I have seen runted specimens as small as 13 mm. 

 expanse.
