Dr. Barry D. Valentine deserves thanks for the use of his personal library. Dr. A. Zheloc'noutsev (Soviet Union) and Dr. P. Ardoin (France) deserve special thanks for making comparisons of specimens in their respective countries with specimens sent to them. Special thanks to T. J. Spilman, United States Depart­ ment of Agriculture, for consultations and considerations extended to me during my visits to Washington. His excellent knowledge of the literature was most helpful. I am most grateful to Dr. Charles A. Triplehorn for serving as my adviser. His guidance and help with the many technical problems encountered in this study was of the highest caliber. Above all, his encouragement and personal interest contributed greatly to making my doctoral pro­ gram pleasant. The excellent photographic skill of Glenn Berkey, Ohio Agricultural Research and Development Center, is gratefully acknowledged. The assistance of the taxonomists in Room 373 has been most helpful, especially Dr. W. T. Schultz and Eric H. Smith. Special thanks to Eric for his advice and help in preparing the illustrations. This study was supported in part by a Grant-in-Aid of Research of the Sigma Xi Research Foundation, Mew Haven, Connecticut, an Ohio State University Dissertation Fellow­ ship and the Osburn Fund of The Ohio State University.
