To Our Patrons. 
If sufficient support is given to this edition of the “ Directory, ” 
it is our purpose to issue an annual supplement giving additional 
names, corrections, etc., and when the present edition is exhausted, 
a new and more complete one will be published. To assist in this, 
kindly advise us of any errors that may be noticed, and also the 
names and addresses of persons interested in Entomology not already 
given herein, together with any suggestions in the way of improve- 
ment.
