Baron Osten Sacken, 



By J. M. Aldrich. 



(Plate XI) 



Karl Robert Romanovich, Baron von der Osten Sacken, 

 commonly known among entomologists as C. R. Osten Sacken, 

 was born in St. Petersburg, August 21, 1828, and died at his 

 home in Heidelberg, Germany, on May 20, 1906. 



In 1849 young Osten Sacken entered the service of the Rus- 

 sian Imperial Foreign Office. After some years of apprentice- 

 ship in diplomacy, he was in 1856 appointed Secretary of Le- 

 gation in Washington. In 1862 he was made Consul General 

 for Russia in New York Cit3% and held the position until 1871, 

 when he retired from the diplomatic service. After several 

 journeys to Europe and back, he again settled in the United 

 States, this time as a private citizen, and remained until 1877 ; 

 in this year he returned to Europe, making his home in 

 Heidelberg the remainder of his life. 



From 1856 to 1877, it will be seen, Osten Sacken was almost 

 continuously a resident of the United States. Before this he 

 had begun to work on Diptera, especially Tipulidse. Imme- 



We have received two interesting accounts of the life of Baron 

 Osten Sacken, who may almost be called an American entomologist. 

 These are by two eminent dipterists, and, not caring to discriminate, we 

 decided to publish both. — Eds.
