Agriculture and one of the leading authorities on American coleoptera. 
at the direction of Dr. L. 0. Howard, Chief of the Entomological Divi- 
sion, kindly went over my entire manuscript and filled in all gaps in the 
known distribution of the various species so far as he could supply the 
information from his extended knowledge of the subject. My thanks are 
therefore due to Dr. Howard and Mr. Schwarz : also to Prof. H. F. Wick- 
ham, of the University of Iowa, for information and assistance. 
The material herein listed, except where otherwise specifically stated, 
was all collected by myself during the season of 1895, while acting as 
Temporary Field Agent of the Entomological Division of the United 
States Department of Agriculture, under the direction of Dr. L. 0. 
Howard, to whom I am again indebted for the opportunity of publishing 
these results. While my own work in the Lower Rio Grande Valley was 
the first entomological work ever undertaken in that region, it was mate- 
rially supplemented the same season by that of Mr. Schwarz and Pro- 
fessor Wickham, who arrived in June and July, after I had been in the 
field for four or five months, and who secured a large amount of material 
in the limited time at their disposal. Both gentlemen have already pub- 
lished some preliminary results of their work, the titles of which will be 
found in the bibliography at the end of this list.
