It is with great regret that we have to record the passing of 

 Otto Heidemann, who died on November 17, 1916, at the age of 

 seventy- three. For many years he has been in charge of the 

 Hemiptera in the United States National Museum, faithfully 

 performing the arduous routine duties of the position, and yet 

 finding time to publish a considerable number of contributions to 

 the literature of his specialty. More than this, he was always 

 ready to share his great knowledge of the Hemiptera with all who 

 sought his advice, and it can safely be said that a large part of the 

 hemipterological work published in America since the days of 

 Uhler has been based upon his store of information, avowedly or 

 not. Thoroughness in his work, kindliness in his relations with 

 others, and self effacement when his own interests were at stake 

 went to make up a rare nature which can ill be spared. 



Through the kindness of Mr. John Howard Paine we are enabled 

 to present in this issue a very excellent and characteristic por- 

 trait of Mr. Heidemann.
