DEPARTMENT OF AGRICULTURE, DIVISION OF ENTOMOLOGY, Washington, D. 0., June 12, 1889. SIR In the absence of Professor Riley, who is now at the Paris Exposition in official capacity, Ibeg tosubmit forpublicationParts I, II, and III of the Bibliography ofAmerican EconomicEntomology, which was ordered by Congress in July, 1882. Owing to various unforeseen delays this work has not yet been completed. Its preparation was originally assigned by Professor Riley to Mr. B. Pickman Mann, formerly of this Division, and upon the severance of his connection with the Depart- ment, in the fall of 1885, it was turned over in an incomplete and fragmentary condition to Mr. Samuel Henshaw, of Boston, who has added greatly to it and practically rewritten the portions already prepared. The extent of the work renders it advisable to publish it in several parts, and as there is unquestionably a more urgent need on the partof working economic entomologists for a bibliography of the writings of B. D. Walsh and C. Y. Riley than of others, on account of their great number and value, these portions have been finished first. Their imme- diate publication will probably antecede the publication of the final part only by a few months. Very respectfully, yours, L. O. HOWARD, Hon. J. M. RUSK, Secretary of Agriculture. Acting Entomologist. TABLE OF CONTENTS TO PARTS I, II, AND III. Page. Introduction, 7 The writings of B. D. Walsh 1860-1873 The joiut writings of B. D. Walsh and C. V.

Few will be likely to criticize the association ofthe names ofWalsh and Eiley in a list ofthis kind, so largely devoted to economic entomology, or to question the desirability of collating their writings in advance of others. As recognized authorities upon entomology, especially from an economic standpoint, their writings have been extensively quoted sometimes with, but frequently without, credit in the agricultural and horticultural journals of the day. These secondary references, though of a certain value when the original is inaccessible, have, as a rule, been omitted. In citing such as are given I have used my personal increased the size of the list judgment. To have given all would hive considerably with but a slight increase in its usefulness. Occasionally, a publisher to meet some popular demand puts the writingsof an author into book form without the knowledge of the latter. Such an occurrence has happened more than once with Dr. Eileys writings. To mention but one In 1877 Messrs. Gteorge Eut- ledge Sons, of London, published The Colorado beetle, with sug- gestions for its repression and methods ofdestruction, with Dr. Eileys name upon the title-page as author...
