INFORMATION TO USERS This reproduction was made from a copy of a document sent to us for microfilming. While the most advanced technology has been used to photograph and reproduce this document, the quality of the reproduction is heavily dependent upon the quality of the material submitted. The following explanation of techniques is provided to help clarify markings or notations which may appear on this reproduction. 1.The sign or “ target” for pages apparently lacking from the document photographed is “ Missing Page(s)” . I f it was possible to obtain the missing page(s) or section, they arc spliced into the film along with adjacent pages. This may have necessitated cutting through an image and duplicating adjacent pages to assure complete continuity. 2. When an image on the film is obliterated with a round black mark, it is an indication of cither blurred copy because of movement during exposure, duplicate copy, or copyrighted materials that should not have been filmed. For blurred pages, a good image of the page can be found in the adjacent frame. If copyrighted materials were deleted, a target note will appear listing the pages in the adjacent' frame. 3. When a map, drawing or chart, etc., is part of the material being photographed, a definite method of “sectioning” the material has been followed. It is customary to begin film ing at the upper left hand corner o f a large sheet and to continue from left to right in equal sections with small overlaps. I f necessary, sectioning is continued again-beginning below the first row and continuing on until complete. 4. For illustrations that cannot be satisfactorily reproduced by xerographic means, photographic prints can be purchased at additional cost and inserted into your xerographic copy. These prints are available upon request from the Dissertations Customer Services Department. 5. Some pages in any document may have indistinct print. In all cases the best available copy has been filmed. University Microfilms International 300 N.

Johnston Susan W. Fisher Norman F. Johnson Adviser Department of Entomology Copyright by Warren C. Welbourn Jr 1985 ACKNOWLEDGEMENTS I wish to thank my advisor, Dr. Donald E. Johnston, for his advice, assistance and patience during this study. Very special thanks go to my wife and family for their continuing support. Funds for my 1984 trip to the British Museum (Natural History), London, Museum National D’Histoire Naturelle, Paris, Museum D ’Histoire Naturelle, Geneva and Istituto Spermentale per la Zoologia Agrara (Berlese Collection), Florence and related field work in England and Italy was supported by a National Science Foundation Dissertation Grant (BSR-8401206). Travel from Florence, Italy to University "Al. I. Cuza." in Iasi, Romania was partially supported by an Ohio State University Graduate Student Alumni Research Award. My visit to the Smithsonian Institution in April, 1981 was supported by a Visiting Researcher Grant from the Smithsonian Institution. I would like to acknowledge the assistance of Ms. Anne Baker, Dr. Don Macfarlane, Mr. Keith Hyatt and Mr. Keiren Martin in the Arachnid Section, of the British Museum (Natural History), London, for their assistance in 1982 and 1984 and arranging for loans of important specimens. I also want to thank Mrs. Judith Marshall (Entomology) for her assistance in my examination of the Orthopteran collections for mites. I am especially grateful to Anne Baker and Paul Hillyard for arranging a very successful spring 1984 collecting trip to south Wales. I also want to thank Clive and Diane Bowman for their hospitality during my two visits to London. I want to acknowledge Dr. Yves Coineau, Director of the Laboratory of Arthropods, Paris for his assistance while in Paris, as well as Mr. Michel Naudo for his patience and assistance as well as arranging for the loan of important specimens. I am especially grateful to Dr. Pierre Robaux for opening his laboratory to me and for the stimulating discussions on trombidioid mites, in addition to his hospitality. I am also grateful to Dr. Bernard Hauser of the Geneva Natural History Museum for his assistance in locating specimens in the Vercammen-Grandjean collection. I am indebted to Dr. Fausta Pegazano for her assistance in making ray visit to the Berlese Collection successful. Dr. Roberto Nannelli is appreciated for his assistance and taking the time to take me collecting at several of Berlese's collecting localities in the mountains around Florence. I wish to gratefully thank Dr. Libertina Solomon for providing space in her laboratory and locating trombidioid specimens in the Feider Collection. I am especially grateful for her family's hospitality while I was in Iasi. The 1982 field work in California and Oregon was supported by a small grant from The Ohio State University to Dr. Donald E. Johnston. I thank Dr. G. W. Krantz for opening his laboratory to us, and Dr. David Walter for his assistance in Corvallis. I acknowledge Drs. G. W. Wharton and G. R. Needham of the Acarology Laboratory for their assistance, interest and support. I am especially grateful to Dr. Edward Baker for his continuing assistance in locating missing specimens and lost literature. I also thank Drs. Evert E. Lindquist (Agriculture Canada) and John B. Kethley (Field Museum Natural of History, Chicago) for their consultation and support. I am especially indebted to the many people who loaned and/or donated specimens for this research. In addition to the persons mentioned above I thank Dr. B. Feldman-Muhsam (Hebrew University Hadassah Medical School, Jerusalem), Dr. Torbjorn Kornestedt (Naturhistoriska Rimsrauset, Stockholm), Dr. David Lee (South Australia Museum), Drs. Ian Smith and Evert Lindquist (Agriculture Canada, Ottawa), Dr. L. van der Hamraen (Rijksrauseura voor Natuurlijke Historie, Leiden), Drs. R. G. Beer and G. W. Byers (Snow Entomological Museum, University of Kansas), Dr. H. Levi (Museum of Comparative Zoology, Harvard University), Dr. Norman Platnick (American Museum of Natural History, New York), Dr. Gary Mullen (Auburn University, Auburn), Dr. Barry M. OConnor (Museum of Zoology, University of Michigan, Ann Arbor), Dr. Donald Tuttle (University of Arizona Experiment Station, Yuma), Dr. John Moser (USDA, Forest Service, Southern Forest Experiment Station, Pineville), Dr. John B.
