differs from the females of both neumoegeni and polingi in that the 

 spot at the end of the cell of the primary, while almost joined to the 

 s. t. band, is enough disconnected so that it appears as a spot in the 

 cell, instead of appearing as a fork of the band ; the male differs by 

 the conspicuous grey apical shade on the under side of the primary.

There is considerable confusion in the literature regarding the 

 present species. Abbott and Smith's description and plate clearly show 

 true ganrce to have brownish secondaries with a paler median band and 

 a blackish outer band ; which is what Mr. Henry Edwards de- 

 scribed as circcp, a specimen having been compared with the type 

 (Neumoegen Collection). The type locality of both names is Georgia. 

 There are three specimens in the Barnes Collection, and another before 

 the authors thru the kindness of Mr. B. Preston Clark, all from Ala-
