 Eucosma isospora Meyrick, Ent. Mo. Mag., vol. 48, 1912, p. 34. 



This species is represented in the collections only by females, so the 

 generic reference can not be made with absolute certainty. I have 

 little doubt, however, that it belongs in Eucosma. It is unique and 

 not easily confused with any other species.

If similana Clemens {confluatia Kearfott), dificsana Kearfott, 

 and engelana Kearfott can be retained as good species or even varie- 

 ties, which I doubt, the synonymy will be restricted as above.
