LETTER OF TRAXSMITTAL. 



U. S. Department of Agricultuhe, 



Bureau of Entomology, 

 WasJiingtmi^ D. 6'., August 31^ 1906. 

 Sir: I have the honor to submit for publication a manuscript enti- 

 tled ''The San Jose or Chinese Scale," which is a thoro revision of 

 the previous publications on this subject issued by the Department, 

 nameh\ Bulletins Xos. 3 and 12, new series, of this office. In spite 

 of the large number of articles which have been published concerning 

 this insect in experiment station bulletins and in journals and maga- 

 zines, there is a distinct need for a comprehensive treatment of this 

 most important subject, and this need, I think, has been met in an 

 excellent way by Mr. Marlatt in this manuscript. I recommend that 

 it be published as Bulletin ><'o. 02 of this Bureau. 



Respectfully, 



L. O. Howard, 



Entomologist and Chief of bureau. 

 Hon. James Wilson, 



Seci'etary of Agriculture.
