LETTER OF TRANSMITTAL. 
MB. HENSHAW’S INTRODUCTORY NOTE. 
The publication of the final part of this bibliography renders an acknowledg¬ 
ment of the assistance received desirable. 
Messrs. A. J. Cook, C. H. Fernald, S. A. Forbes, L. O. Howard, H. Osborn, F. M. 
Webster, and C. M. Weed kindly furnished data concerning their several publica¬ 
tions, and the printed lists of Messrs. Asa Fitch, Townend Glover, T. W. Harris, 
William Le Baron, and J. A. Lintner have been freely used. The work of Messrs. 
A. S. Packard and J. S. Kingsley in the first stages of the bibliography should also 
be mentioned, and I especially desire to add an explicit recognition of the work of 
Mr. B. P. Mann. 
Though an exact agreement between Mr. Mann and myself does not seem possible, 
I most willingly acknowledge that his work, especially in Part III, was both exten¬ 
sive and important. The original plan of the bibliography, like the bibliographical 
record published in “Psyche,” was conceived by Mr. Mann, and during his connection 
with the Division of Entomology, from September 1, 1881, to December 31, 1886, he 
completed several thousand titles, besides amassing a large amount of miscellaneous 
data. I supplemented Mr. Mann’s work with additional material and rewrote; 
reviewed, and, when possible, condensed the analytic notes of the parts jirepared 
by Mr. Mann; introduced a uniform nomenclature of the scientific names, made the 
several indexes wholly anew, and read the proof. 
Samuel Henshaw. 
Cambridge, October 12, 1896. 
By mutual consent of Messrs. Mann and Henshaw the evidence upon 
which these two notes are based has been submitted to Dr. Theodore 
N. Gill, as an unprejudiced arbiter of the question as to the true author¬ 
ship of the volumes. Dr. Gill decided, in a letter to the Assistant Sec¬ 
retary of Agriculture, dated April 20, 1S9G, “that the credit for the 
work and right to appear on the title page as editor properly belong 
to Mr. Henshaw. 7 ’ 
The present part completes the work which can be done under the 
authority of the joint resolution of Congress dated July 0, 1882. It 
brings the Bibliography of American Economic Entomology down to 
June 30, 1888. 
Efforts will be made to bring the bibliography down to date and to 
publish thereafter occasional supplements. 
Respectfully, L. O. Howard, 
Entomologist. 
Hon. J. Sterling Morton, 
Secretary of Agriculture.
