U.S. NATIONAL MUSEUM BULLETIN 227 



This study was aided by grants from the National Science Founda- 

 tion (NSF G-526, G-2012, G-4833) and from the Central University 

 Research Fund of the Graduate School of the University of New 

 Hampshire (CURF-50). The writer acloiowledges her appreciation 

 to the National Science Foundation for continued support on the 

 project; to the University of New Hampshire for both support and 

 leave time, and particularly to Dr. George M. Moore, whose interest 

 and help throughout the project have been invaluable; and to the 

 authorities of the U.S. National Museum for allowing her to make use 

 of the facilities of the Institution, and especially to Dr. Fenner A. 

 Chace, Jr., and Dr. Frederick M. Bayer for their help on taxonomic 

 and other problems, to Mrs. Lanelle Peterson for her help in uncover- 

 ing many rare "gems," to Dr. Waldo L. Schmitt for his enthusiastic 

 prodding, and to the librarians for their invaluable aid in helping 

 to obtain necessary and often difficult-to-find literatiu'e. 



It is my hope that the second and concluding part of this study will 

 be completed in the next few years.
