Excerpt from Revision of the North American Moths of the Subfamily Eucosminae of the Family Olethreutidae It is the author's conviction that in the Olethreutidae venational changes Of the hind wings are the characters of most fundamental import. On these characters - with the exceptions of a stalked 6 - 7, easily and at different places derived from the normal approximate condition of these veins, and the united 3 - 4 derived equally readily from a stalking of 3 - 4 - the genera fall into larger natural groups to which, for convenience of handling, subfamily names are given.
