 most interesting material collected in Kansas, New Mexico, and 

 Colorado. 



The late Beverly Letcher permitted me to study a series of speci- 

 mens that had been collected along the Colorado River in Arizona. 



Lieut. Col. Thos. L. Casey donated several of his species and 

 other specimens. Eleodes rileyi was of particular interest. 



The California Academy of Sciences, of San Francisco, placed its 

 material at my service. The collection was of more than ordinary 

 interest on account of material from Lower California.

 County, California. 



I received from Mr. Edward Ehrhorn a small collection from the 

 mountains at Monte Bello, near Mountain View, Santa Clara County, 

 California. 



My friend and colleague. Dr. William Lee Moore, and his son 

 Edgar, collected a large series at Verdi, Nevada, and sent the same 

 to me.

 at San Diego, California, and transmitted most of them alive for 

 special studies.

 taken about Nogales, Arizona, and also permitted me to study those

 mens from about Nogales. 



Dr. A. Fenyes very kindly sent me material for examination and 

 study. 



Prof. F. H. Snow, of the University of Kansas, permitted me 

 to study and identify numerous specimens collected by himself in 

 Arizona and elsewhere. 



Dr. R. H. Wolcott, of the University of Nebraska, transmitted to 

 me the entire collection of Eleodes of that institution for study, and 

 also a collection of Mexican species. 



I most sincerely thank Mr. Charles O. Waterhouse, of the British 

 Museum, Cromwell Road, London, for a series of Blaps, Avhich he 

 very kindly loaned in response to my request. 



Miss Julia Wright, of Palo Alto, California, allowed me to study 

 the native species in her collection, also a collection of Blaps obtained 

 by her while abroad. 



I also looked over the collection in the entomological depart- 

 ment of Stanford University, through the courtesy of Prof. Vernon 

 Kellogg. 



It is my duty and pleasure to thank all who have so promptly 

 aided me, and especially my intimate associates. Dr. Edwin C. Van
