Excerpt from Check List of the Lepidoptera of Boreal America It has seemed to us therefore that the publication on our part of this present list may be of some value to students of Lepidoptera who wish not only to arrange their collections but to have before them in a concise form the latest views on the classification of this order of insects. In general this list is based on the latest revision of each group, combined in many instances, more especially in the so-called Macrolepidoptera, with work which has been carried on for several years in the Barnes Collection in connection with the study of the existing types of North American species and the comparison of specimens with these same types; the synonymy of each species is given as fully as possible in so far as it relates to species described from North American material, and we have incorporated a number of changes in the list which have been commented on in several papers by ourselves which recently appeared in print.
