Discussion: F. lacticaput m&y be separated from cockerelli, caieta, 

 repentina, and nona by the presence of the buff white to white costal 

 fascia at one-third; and from acactella and infracta by the head and 

 anterior half of the thorax being buff. 



Forewings of the fresh specimens are nearly black with a slight 

 luster as contrasted with the dark brown of the specimens collected 

 for the "Biologia."
