2 28 NATURAL HISTORY BULLETIN. 



The preparation of this paper was begun five years ago 

 and has proceeded with more or less interruption up to the 

 present. My thanks for aid are due to most of the active 

 Coleopterists of the country, since help in one form or another 

 has been rendered by nearly all. I wish, however, to acknowl- 

 edge special indebtedness to these: the late Dr. Geo. H. Horn, 

 who was always ready to examine puzzling forms; Mr. Henry 

 Ulke, who gave me names of many species during the earlier 

 years of my entomological studies; Major Thos. L. Casey and 

 Mr. Chas. Liebeck for identifications in special groups; Mr. 

 Roland Hayward for names of Bembidium and for a very 

 large number of manuscript records; Mr. Fred. C. Bowditch 

 and Prof. T. D. A. Cockerell for manuscript records; Prof. 

 C. P. Gillette for allowing me to examine the entire collection 

 of the Colorado Agricultural College and afterwards sending 

 data corresponding to the accession numbers; and finally to 

 my wife who has done the major part of the bibliographical 

 and clerical work in connection with the preliminary construc- 

 tion of the catalogue.
