FOREWORD 
This number of the Monthly Letter of the Bureau of Entomology in-— 
augurates a different type of news letter, one which it is believed will 
be more creditable to the Bureau and more informing and stimulating to its 
personnel. The material has been selected from various monthly reports 
and is intended to give, in the form of brief notes, a current picture 
of the important work of the Bureau. The information included in the 
letter is not for publication; or further distribution, without specific 
permission from the Washington office. The Monthly Letter is now to be 
looked upon as a "house organ" issued with the thought of keeping the 
workers of the Bureau advised of the work under way. It is believed that 
this information will be beneficial to the Bureau as a unit and that it 
will lead to a better understanding of the functions and activities of 
the Bureau. With this number the mailing list has been revised and the 
distribution practically limited to members of the Bureau. 
It is planned to give credit directly or indirectly for observa— 
tions and special notes. Any original observations which may be includ- 
ed will, therefore, be a matter of more or less permanent record. 
Should readers want further information concerning any of the 
statements included in the Monthly Letter, they should make inquiries 
through the regular channels of correspondence, i.e., through division 
leaders and other supervising officers.
