Excerpt from Revision of the North American Moths of the Subfamilies Laspeyreshnae and Olethreutinae
This paper is a continuation of the revisionary work of the family Olethreutidae, begun in United States National Museum Bulletin 123 and treats of the two remaining subfamilies, Laspeyresiinae and Olethreutinae. It is based chiefly upon the collections of the United States National Museum, the American Museum of Natural History, the Canadian Department of Agriculture, and of Dr. William Barnes, of Decatur, III. In addition I have examined the types of the Museum of Comparative Zoology and the Philadelphia Academy of Sciences. I have also received considerable material from E. H. Blackmore and Dr. W. T. M. Forbes, and Dr. J. McDunnough has kindly loaned the genitalia slides of his types.
The classification here proposed follows that of my revision of the Eucosminae and the method of treatment of genera and species is the same except that characters of the female genitalia are included and a drawing of these organs given for every species of of which a female could be secured. For those species common to Europe and North America purely European synonymy is omitted. Otherwise generic and specific synonymy is given as fully as possible and, except where so noted in the text, has been verified by comparison with types or other authentic specimens. In each case the more important systematic references are given; and for species of economic importance, citations to the papers giving the fullest accounts of life history, distribution, and control.
