ACKNOWLEDGMENTS In the Name of Allah, Most Gracious, Most Merciful I would like to express my sincere appreciation to my major advisor, Professor Clarence J. Goodnight, for his supervision throughout the progress of this study and his helpful criticism of this manuscript and stimulating discussion which have contributed greatly to my understanding of scorpions. Sincere thanks also go to Professor Joseph G. Engemann and Professor William VanDeventer for their helpful comments. I would also like to express a very deep sense of thanks to the Zoology Department, Faculty of Science, at A1 Fateh University, Tripoli, Libya, for providing me with the most generous help to carry out this work. Gratitude is extended to the Dean of the Faculty of Science, Dr. Tahar Rabte, for his assistance and cooperation. Special thanks go to my parents and my wife, Amal, for their encouragement and help and also to the graduate students Fardin Oliaei and Julie Medlin for their assistance in drawings and taking pictures.

INFORMATION TO USERS This was produced from a copy of a document sent to us for microfilming. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the material submitted. The following explanation of techniques is provided to help you understand 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 are spliced into the film along with adjacent pages. This may have necessitated cutting through an image and duplicating adjacent pages to assure you of complete continuity. 2. When an image on the film is obliterated with a round black mark it is an indication that the film inspector noticed either blurred copy because of movement during exposure, or duplicate copy. Unless we meant to delete copyrighted materials that should not have been filmed, you w ill And a good image o f the page in *he adjacent frame. 3. When a map, drawing or chart, etc., is part of the material being photo graphed the photographer has followed a definite method in “sectioning” the material. It is customary to begin filming at the upper left hand comer of 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 any illustrations that cannot be reproduced satisfactorily by xerography, photographic prints can be purchased at additional cost and tipped into your xerographic copy. Requests can be made to our Dissertations Customer Services Department. 5. Some pages in any document may have indistinct print. In all cases we have filmed the best available copy.

CHAPTER I Introduction Members of the Class Arachnida belong to the Phylum Arthropoda, the joint-footed animals. Members of this class may be found in nearly all areas of the world, tending to be numerous in the warmer areas and less abundant in colder regions. Among the Arachnids, one order, the Scorpionida, has representa tives throughout the warmer regions of the earth. Since the stings of many scorpion species are highly toxic to humans, their biology is of special interest to students who encounter medical problems in volving the scorpions. All species possess a poison sac at the base of the terminal sting. Fortunately only a few are actually dangerous to humans. An exception to this generalization may be found in North Africa where a large percentage of the species have venom which is highly toxic to humans. As a matter of fact, there are areas in which the scorpions constitute one of the most important problems encountered in North Africa, particularly in the interior of the Sahara Desert. Until relatively recent times, communication in Libya was con fined to
