Excerpt from The Mexican Cotton Boll Weevil: A Revision and Amplification of Bulletin 45, to Include the Most Important Observations Made in 1904 The present bulletin is based upon Bulletin N o. 45, of this Bureau entitled The Mexican Cotton Boll Weevil, issued in May, 1904. That publication included the results of investigations of this impor tant pest which had been carried on for several years. The present bulletin includes additional results that were obtained during the sea son of 1904. In form the principal changes are in the incorporation of the treatment of some 50 additional topics. AS a matter of fact, however, Some of the principal actual additions are incorporated in the tables which occur throughout the pages of the bulletin. Many additional features of the life history of the pest that may throw light upon the question of combating it have been investigated. In some respects'very considerable additions to our knowledge of the insect have been made. This is especially the case in all matters relating to dissemination. This topic deals with matters that are naturally dith Cult to determine. The work must be done in the field, and a large territory must be covered. Through the cooperation with the Louisi ana Crop Pest Commission, which was engaged in an attempt to pre vent the further advance of the boll weevil into that State, a number of entomologists occupied several months' time in the extreme eastern and northern regions infested by the pest. It is, of course, only upon the basis of such a complete knowledge of all means by which the weevil leaches new regions that the possibility of checking its advance may be considered.
