[Note. — During the years 1864 to 1876, inclusive, the Department of Agriculture 

 published regularly monthly reports, mainly statistical in their character (replaced 

 since 1876 by the series of monthly "Crop Eeports"), but which contained many 

 short articles by the Entomologist, none of which would come within the scope of 

 the present bulletin. Reference to these articles may be facilitated by consulting the 

 "Synoptical Index of the Reports of the Statistician, 1863-1894" (Bui. No. 2, Division 

 of Publications, Department of Agriculture). In like manner the "Index to the 

 Annual Reports of the Department of Agriculture, 1837-1893" (Bui. No. 1 of the 

 same series), maybe used to facilitate reference to the entomological reports, articles, 

 and notes appearing in the Annual Reports of the Department.
