PREFACE. 
The publications of the commission will consist of circulars, bulletins, 
memoirs, and the annual report of doings and results of the work of 
the Commission. The bulletins will contain such special information as 
may be of interest and importance at the time of publication. They 
will be issued partly in anticipation of the annual report, and i)rincipally 
to meet the demand for information and the numerous inquiries made 
of the Commission at the time. The present number has exclusive 
reference to the destruction of the young insects which will so largely 
occupy the attention of our western farmers for the next two months. 
It will be at once followed by a second number on the natural history 
and habits of the species.
