The following catalogue of the exhibit of economic entomology 
made by the Bureau of Entomology, U.S. Department of Agriculture, 
at the Lewis and Clark Centennial Exposition, will, it is believed, 
increase the usefulness of the exhibit by furnishing the visitor, in a 
convenient form for future reference, much of the data contained on 
the labels, and by supplying him with references to published articles 
from which additional information can be gained. 
The catalogue has been compiled from Bulletins Nos. 47¢ and 48? of 
this Bureau and includes all portions of each of these bulletins, revised 
and corrected, which relate to the exhibits installed at Portland. 
Owing to the fact that less space was available for the exhibit by 
the Bureau of Entomology at Portland than at St. Louis, it has been 
necessary to reduce the size of the exhibits considerably, and this has 
in most part been accomplished by leaving out insects which affect 
strictly eastern or southern crops. In other respects, however, the 
exhibit is very similar to that made at St. Louis, and includes all those 
features which proved of especial interest there. Care has been taken 
to retain such insects as are of especial importance on the Pacific coast 
and those which affect important Pacific coast industries, such as fruit 
raising and lumbering. 
Persons desiring further information than can be gained from this 
catalogue, or from conversation with the attendant in charge of the 
exhibit, are requested to address the writer at the U. S. Department of 
Agriculture, Washington, D. C.
