t Euleia Walker is the older name but there is considerable doubt about the identity of the 

 genotype and I use Myoleja to avoid confusion. 



± Acidia fratria Lcew belongs here. 



§ Curran, 1032. Amer. Mus. Novit. No. 526, p. 3. 



1 A large species resembling the sjiecies of Pyrgota but distinguished by wing venation, 

 presence of strong ocelli, shape of the head. etc. The genotype is crassipes n.sp. from Panama.
