202 PROCEEDINGS ENTOMOLOGICAL SOCIETY 



d^tto ^etfcemamt. 



By the death of Otto Heidemann on November 17, 1916, our 

 society lost one of its oldest and most valued members. In 

 many respects he was a remarkable man; taking up Entomo- 

 logical studies late in life well beyond fifty he rose in a few 

 years to the rank of an authority on his chosen group, an achieve- 

 ment which would have been impossible for one less gifted. With 

 a natural aptitude for systematics and a ready grasp of the larger 

 problems of scientific investigation, he combined a painstaking 

 carefulness of small details, untiring energy and the trained eye 

 and skilled hand of the artist. Many excellent illustrations of 

 insects bear witness to his ability as an engraver. One of these, 

 adorning the cover of our proceedings and adopted as the official 

 seal of this society represents the adult male of Rheumatobates 



1 rileyi Renter and is the only authentic record of a fully winged 

 male of that peculiar insect in existence. His collection of local 

 Hemiptera, is a splendid model of what an modern insect collec- 

 tion should be and shows his exacting care for correctness in even 

 the smallest details. He was a man of broad culture, a peer 

 among the leading contemporary Hemipterists, a writer of plays 

 in both German and English, several of which have achieved 



' public performance, a scientific artist of the very first rank and an 

 earnest student of the social problems of our day. More than all 

 he was a man of lovable and unimpeachable character, ever ready 

 to help others, gentle, cheerful and unassuming to the point of 

 humility. Respected by all who knew his work, loved by all 

 who knew him personally.
