 Hampson uses the term puta for this species, and does not recog- 

 nsze tlie change made by Grote and Robinson because their term 

 first proposed was pre-occupied. If puta was actually a nomen bis 

 ledum in Xanthia when proposed, irrespective of whether it was 

 actually congeneric with the pre-existing puta, the authors had a 

 right to change the specific name, and having properly done so they 

 must be followed, even though the tvfo puta prove later to be gener- 

 ically separable. 



In"^ the series before me there is a curious dimorphism in the 

 females; some of them have the wing form of the male and resem- 

 ble it closely in maculation ; others differ in having the primaries 

 distinctly longer and much more definitely marked, the median 

 shade especially being very well defined and obviously angulated. 

 It really looks very much like aggressa. I have never seen a male 

 of this form and it seems locally so uniformly associated with the 

 normal male of euroa that I can scarcely believe it distinct. The 

 character used by Hampson in his table, i. e., the quadrate orbicu- 

 lar open to the costa is not constant, a closed oval being about as 

 frequently present as the open quadrate form. I have had the 

 specimens from Mrs. C. H. Fernald's collection, from the collection 

 of the U. S. Nat. Mus., from the Museum of the Brooklyn Institute, 

 and have examined those in the Amer. Mus. of Natural History. 



Localities are St. Catherines, Ontario; Kittery Point and Orono, 

 Maine ; Bufl'alo, Centre and Sharon, New York. Dates range from 

 the middle of August to the middle of September. 



Other recorded localities cover the eastern United States west to 

 the Mississippi and southwest to the District of Columbia. Colo- 

 rada is also included, but that may be based on what I have sepa- 

 rated as aggressa; and Calgary, Alberta, given by Hampson, almost 

 certainly refers to my duscata. Though so widely distributed, I 

 have never known the species to be common, and it is distinctly 

 northern in range, more examples in collections coming from 

 "Maine" than from any other one locality. 



The sexual characteristics are elsewhere described.
