John Wilcox's wealth of information about the Chrysomelidae, which was freely shared, is greatly appreciated. Help from office mates Eric Smith and Dr. Robert W. Hamilton, who traveled this route ahead of me and pointed out some of the pitfalls, is here acknowledged. Jean Mims did a wonderful job in typing the final manuscript. My adviser, Dr. Barry Valentine, is sincerely thanked for his help in unraveling taxonomic mysteries, finding literature, and comparing specimens with types in European museums; for his patience in carefully reading and correcting this manuscript; and for his faith in me and in this work. Finally I wish to thank my wife, Margaret, for her aid in typing, mapping, recording data, and all the other busy work items which she cheerfully accomplished; and for her encouragement and companionship throughout the completion of this work. iii VITA August 7, 1942 .............
