INTRODUCTION VII 



The drawings of generic characters were made by Mr. Kakuzo 

 Yamazaki of Tokyo, through the cooperation of Captain Wallace P. 

 Murdock. The drawings of specific characters are mostly by Miss 

 Y. Morimoto, who worked under the direction of Dr. M. Tokunaga of 

 Kyoto, Japan. Figure 284 is from drawings by Miss M. McKay of 

 the Canadian Department of Agriculture, lent for inclusion in this 

 paper. Photomicrographs of genitalia are by Mr. John Alley of 

 the University of Michigan Photographic Services. The Scambus 

 drawings in figures 310-312 were supplied by G. S. Walley and those 

 of Delomerista in figures 313 and 316 by Luella Walkley. Mrs. 

 Rosemary Frey and Miss Sharon Carey assisted with making the 

 maps showing distribution. Typing was mostly by Mrs. Frey and 

 Miss Ellen Linn a. 



When this paper was begun, four other students of the Ichneu- 

 monidae had already started on revisions of the genera Scambus, 

 Delomerista, Poemenia, and Aplomerus; they have all agreed to include 

 their work as parts of the entire revision, for the convenience of future 

 students who would prefer a complete treatment, all under one cover. 

 Although included in this revision and conforming with its style to 

 some extent, these papeis are independent contributions. 



Other parts of this publication are by Henry and Marjorie Townes, 

 as joint authors, but those portions that validate new generic, specific, 

 and subspecific names are the work of the senior author alone. Thus 

 their authorship should be "Townes" rather than "Townes and 

 Townes." We make this statement to provide a shorter form for the 

 citation of the author of the names. The same citation, "Townes," 

 is correct for all names in our previous papers, for the same reason.
