The name fuscociliana was omitted from the Dyar and Barnes 

 and McDunnough lists, as Fernald did not recognize the species. 

 The types, or what purport to be the types, of both it and dubiana 

 are in the collection of the Academy of Natural Science at Phila- 

 delphia. They agree with each other and with what Kearfott had 

 in his collection under the two names. I have my doubts that 

 either is anything but a poor variety of laciniana. They average 

 a trifle smaller and there is somewhat more of a yellow suffusion 

 on the white areas and in the cilia of the forewing, but otherwise 

 there is little difference. In genitalia structure there is nothing 

 to separate fuscociliana from laciniana, or for that matter from 

 hurgessiana or platanana, and in a long series of collected adults 

 from a given locality there is even a gradual transition in color 

 and pattern from typical platanana to typical hurgessiana. In this 

 series fuscociliana comes between laciniana and platanana. I am of 

 the opinion that all these forms are nothing but varieties of a single 

 variable species with many food plants. Extensive rearings will be 

 necessary to determine how correct is this assumption. In the mean- 

 time we must keep them under separate names.
