DESCRIPTIONS OF NEW NORTH AMERICAN TINEID MOTHS, WITH A GENERIC TABLE OF THE FAMILY BLASTOBASID.E. By Lord Walsingham, Merton Hall, Thelford. EiKjland. INTRODUCTION. Several papers were published under the title "Steps Toward a Revision of Chambers Index; With Notes and Descriptions of New Species" in Insect Life," a journal published by the U. S. Depart-ment of Agriculture from 1888 to 1895. The object was the gradual improvement of the catalogue of North American Tineid moths by the publication of descriptions of new species and corrections of the generic locations of old ones. The standard catalogue of North American Tineida? at the time these papers were begun was pub-lished by V. T. Chambers under the title ''Index to the Described Tineina of the United States and Canada" in the Bulletin of V. S. Geological and Geographical Survey, IV, No. 1, 1878. During the sixteen years that have elapsed since the last installment of these papers was printed, the journal Insect Life has been suspended, but the series is herewith continued under a more explanatory title. The material on which these descriptions are based was in part received by the U. S. National Museum from the U. S. Department of Agriculture through the late Dr. C. V. Riley, and in part is con-tained in the author's collection. Types of the new species are in the collection of the U. S. National Museum in most cases, as indi-cated by the type numbers, some from the museum material and some donated by the author. Family GELECHIAD^. GELECHIA LAUDATELLA, new species.
