Circular No. 1, New Series, was also published May 11. It includes 

 certain condensed information concerning the more important insecti- 

 cides and is for use in correspondence chiefly. It is the first of a series 

 of this character which we hope to i)ublish in order to meet those ques- 

 tions which experience has shown us to be most often asked by the 

 correspondents of the Division. 



Before this number of Insect Life appears Bulletins 23 and 25 of 

 the regular series will undoubtedly have been published. Bulletin No. 

 23 includes the reports of the field work of the agents of the Division 

 during the year 1890. It is prepared on the same plan as Bulletin No. 

 22 of this series. Bulletin No. 25 takes up the subject of destructive 

 locusts and is a popular consideration of a few of the most injurious 

 locusts of the United States together with the best means of destroy- 

 ing them. It is an emergency Bulletin published chiefly for distribu- 

 tion at present in those portions of Idaho, Utah, and Montana which 

 were overrun last season by non-migratory locusts, but it will also 

 meet the demand for practical information, whenever local or migratory 

 species may appear in destructive numbers. Its publication was neces- 

 sitated by the fact that the First Eeport of the U. S. Entomological 

 Commission and the Annual Eeport of this Department for 1877 are 

 out of print. 



Recent changes in the force of the Division.— We announced on page 310 

 that Mr. C. H. Tyler Townsend had resigned his position in the Division 

 to accept the post of Entomologist to the State Experiment Station of 

 New Mexico. By a competitive civil service examination, held during 

 May, his place has been filled by Mr. F. H. Chittenden, of New York, 

 formerly editor of. Entomologica Americana^ and curator and correspond- 

 ing secretary of the Brooklyn Entomological Society. Mr. A. B. Cord- 

 ley, formerly Entomologist of the Agricultural Experiment Station of 

 Vermont, has also been appointed to a position in this Division. 



REPORT OF A DISCUSSION ON THE GYPSY MOTH. 



[At a Conference held in the rooms of the Committee on Agriculture, Boston, Mass., March 4, 1891.] 



Present, Prof. N. S. Slialer, Mr. F. H. Appleton, and Mr. Wm. E. Sessions, of the 

 State Board of Agriculture, Profs. C. V. Riley and C. H. Fernald, Mayor Craig of 

 Medford, Mayor Gould of Melrose, Mayor Pierce of Arlington, and Mayor Wiggins 

 of Maiden, and others. Mr. S. H. Scudder came in later. 



Professor Shaler. You know that about 20 years ago an interesting Frenchman 

 brought an interesting bug to this country. His name was Trouvelot, and he brought the 

 creature thinking to introduce it as a valuable silkworm. I begged him to destroy his 

 specimens, and at one time he said he had. It appears, however, that they got away 

 from him. Last year I went before the legislature and begged for some money, ad- 

 vising them to put ;§100,000 at the disposition of a trustworthy commission. They 

 appropriated $50,000 and appointed a commission which did a good deal of work and 

 expended a good deal of money and energy. I begged them to bend their energies to
