4 BULLETIN 63, UNITED STATES NATIONAL MUSEUM. 



ACKNOWLEl HJMKNTS. 



It is a great pleasure to acknowledge the generous loan and gift of 

 material, as follows: 



The United States National Museum in Washington made the loan 

 of 1,914 specimens, which were transmitted to me through the kind 

 intercession of Dr. L. O. Howard. This material was of invaluable 

 aid and of great interest, as it contained material from the collections 

 of the following well-known entomologists: H. G. Huhl)ard, E. A. 

 Schwarz, C. V. Riley, H. Soltau, E. J. Oslar, D. W. Coquillett, H. K. 

 Morrison, M. L. Linell, J. B. Smith, J. D. Mitchell, H. S. Barber, 

 C. F. Baker, and A. S. Fuller. 



]Mr. Charles Fuchs and Dr. PI C. Van Dyke put all of their material 

 at m,v disposal. 



I am especially indebted to my friend, Henry C. Fall, for the com- 

 parison of material with authentic types in the collection of the Mu- 

 seum of Comparative Zoology in Cambridge, Massachusetts, and for 

 the loan of species not well represented from other sources. 



To ISIr. Frederick Blanchard, of Tyngsboro, Massachusetts, I 

 extend my sincere thanks for his painstaking care in the comparison 

 of many consignments of specimens from my collection with the Le- 

 Conte types in the collection of the Museum of Comparative Zoology 

 in Cambridge. His valuable notes and short descriptions aided me 

 greatly, and without which I could not have written so authorita- 

 tively. At his request ]Mr. Samuel Henshaw, curator at the museum 

 in Cambridge, very kindly transmitted to me one of LeConte's speci- 

 mens of Eleodes (jentilh. 



At my request Mr. Charles Liebeck, of l*liiladelphia, looked up the 

 literature on Blaps and made notes on specimens in the collection of 

 the Academy of Science in that city. 



Prof. 11. F. Wickham, at the sacrifice of his own limited time, most 

 kindly looked up literature upon the tribe noAv under consideration, 

 and those references that could not be ol)tained upon this coast he 

 copied and forwarded to me, namely, the original descriptions of 

 Mannerheim. I must also thank him for the loan of material, espe- 

 cially for specimens taken in Texas, Nevada, and New^ Mexico. 



I am indebted to Mr. Ralph Hopping for the examination of the 

 material in his collection, especially that from Tulare County, Cali- 

 fornia. T had the privilege of studying a collection taken at Fort 

 Tejon by Messrs. Hopping and Fuchs. 



Prof. J. J. Rivers presented me with a series of Eleodes^ taken at 

 Ocean Park, Los Angeles County. 



Dr. C. F. Clark most kindly contributed a (collection of Eleode^ 

 taken in Napa County, California.
