Kearfott indicated that this might be a variety of spoliana 

 Clemens. I am inclined to think it is only an extreme aberation, as 

 I have seen one or two specimens of the true spoliana which approach 

 it in pattern. There is no differences in genitalia between the two 

 even in the size of the harpes. I have seen only the type of faracana., 

 however, and until more specimens are recovered and something 

 is known of its life history it will have to stand as a distinct species. 



Veins 7 and 8 of fore wing are closely approximate at base.

This species is easily recognized from others in the genus by its 

 clear cut grayish fuscous basal patch and unbroken postmedian 

 fascia. The whitish areas of fore wing at middle and beyond the post 

 median dark fascia extend unbrokenly from dorsum to costa and 

 contain no traces of ochreous shading. Above ocelloid patch there 

 is a grayish fuscous blotch which fuses with a similar dark shade 

 along termen.
