Gross measurements were made with a standard millimeter ruler. 

 The wing expanse was measured from the extreme apex of one wing to 

 that of the other side. In the larval cases, only those which were 

 mature (i.e., which contained evidence of pupal material) were meas- 

 ured. The diameter in all instances refers to the greatest diameter 

 observed along the length of the case. 



Except in those cases where specific aclaiowledgment is given, 

 all photographs were made by the author with an Exakta VX Ila 

 35 mm. camera. Drawings also were executed by the author, usually 

 with the aid of a Kenivision Micro-Projector. Illustrations of some 

 structures (e.g., the male and female genitalia of certain species) have 

 been included to show the similarities in these organs that may exist 

 between different species as well as the differences. 



Definitions of nearly all the terms used in this study may be found 

 in the glossary prepared by Torre-Bueno (1950). Terms relating to 

 the male and female genitalia were in part derived from the discus- 

 sions of Burrows (1923), Forbes (1923), and Klots (1956). Selected 

 illustrations (figures 146-148, 310) have been labeled to show the 

 precise application of many of the terms used in the discussions on 

 wing venation and genitalia. The terminology used in discussing the 

 distributions of the various species follows that of Smith (1935) and 

 Lobeck (1948). 



Many individuals and several institutions together have provided 

 assistance in making this work possible. I wish primarily to express 

 the gratitude I feel toward Dr. Frank Morton Jones (deceased. May 

 1962), whose very fine collection and extensive earlier work on the 

 North American Psychidae provided a firm basis for the present 

 revision. In addition to his valuable collection, Dr. Jones presented 

 a fund of a thousand dollars to the Smithsonian Institution for future
