LETTER OF TRANSMITTAL. 



United States Department of Agriculture, 



Bureau of Entomology, 



Washington , B.C., June 3, 1911. 

 Sir: I have the honor to present for publication a manuscript on 

 the subject "Calosoma Sycophanta: Its Life Historj^ Behavior, and 

 Successful Colonization in Xew England/' by Mr. A. F. Burgess, of 

 this bureau. The insect in question is one of the most important 

 of the natural enemies of the gipsy moth and the brown-tail moth 

 which have been imported from Europe. The work on its life history 

 and the means of establishing it has been in Mr. Burgess's charge. 

 He is particularly skilled in this class of work, and has achieved a 

 notable success in this investigation. 



I recommend that this paper be published as Bulletin Xo. 101 of 

 this bureau. 



Respectfully, L. O. Howard, 



En to m ologist and Chief of B ureau 

 Hon. James Wilson, 



Secretary of Agriculture.
