Family APOPROGENIDAE nov. 



Differs in the key from the Euschemonidae, in which the eyes are not overhung 

 by long cilia and the forewing has all the veins from the cell, in having the 

 eyes overhung by long cilia and the forewmg with veins 7, 8, 9, 10 stalked. Its 

 relationship is with the Sematuridae and Uraniadae and it consists solely of two 

 genera.
