LETTER OF TRANSMITTAL. 
U. S. Department of Agriculture, 
Bureau or Entomology. 
Washington, D. 6 7 ., 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, 
namely, Bulletins Nos. 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 Air. Marlatt in this manuscript. I recommend that 
it be published as Bulletin No. (32 of this Bureau. 
Respectfully, 
L. O. Howard, 
Entomologist and C 7/ ief of Burt <> ", 
Hon. James Wilson, 
Secretary of Ayr/ culture.
