PROCEEDINGS 



OF THE 



ENTOMOLOGICAL SOCIETY 



OF WASHINGTON 

 VOL. XVIII 1916 No. 4 



It is again our sad duty to chronicle the death of an ex-presi- 

 dent, Otto Heidemann, of whom we publish in this number of 

 the PROCEEDINGS an appreciation, a biographical sketch and 

 bibliography, together with a short posthumous paper illustrated 

 with a plate of Mr. Heidemann's inimitable drawings.
