62 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL.84 



In the autumn of 1887 I visited Cambridge with my wife in order 

 to do some work in the Museum of Comparative Zoology in connec- 

 tion with my taxonomic studies of the Chalcididae. Hagen was work- 

 ing alone and in the same way that has been described once or twice 

 in print by J. H. Comstock, especially as reported in Karl Escherich's 

 book on applied entomology in the United States. He was a very 

 courteous man, and insisted on showing Mrs. Howard (then a young 

 Ijride and very pretty) around the Museum while I worked. Mrs. 

 Howard had brought her sewing, and would have been quite con- 

 tent to be Jeft alone ; but Hagen insisted, and Mrs. Howard, without 

 the slightest knowledge of any of the things he showed her and 

 totally unable to understand him, found herself in a predicament 

 which needed all of her tact. As she told it to me afterwards, he pres- 

 ently stopped and said, " You do not understand me." " Oh, per- 

 fectly," she replied ; and was very much taken aback when he re- 

 marked, " Veil, vot did I say ? " 



During this visit Henry Edwards arrived one day with a very large 

 box of Australian insects. He had recently returned from Australia, 

 where he had been acting for some years (he was an actor by profes- 

 sion) and incidentally collecting all sorts of insects. I was immensely 

 impressed by Edwards, tall, handsome, cordial man that he was. As 

 Hagen exclaimed over this or that extraordinary Neuropter, Edwards 

 would say, "You may have it." "Ach! meincr thcurer frcund!" 

 Hagen would say, and would then forcibly embrace him and kiss him 

 on both cheeks. I don't believe Edwards had ever been in Germany, 

 and I think this method of expressing delight was as novel to him as 

 it was to me, and naturally made him very uncomfortable, but he did 

 not show it. 



Hagen was very generous, placed everything at my disposal, trusted 

 me perfectly, and helped me all he could. His opinion on many ento- 

 mological questions was for years the last word in America, and 

 American entomology profited greatly by his coming to America at 

 the instigation of the elder Agassiz. 



In 1893, at the age of y6, Hagen died. Of his four hundred odd 

 published entomological papers, 47 have been recorded as distinctly 

 economic. The majority of these were short articles in the strictly 

 entomological journals. He wrote a number of longer or shorter 

 papers on the subject of the possible destruction of injurious insects 

 by the application of the yeast fungus, and at one time started a 

 controversy by an article that he published, entitled " The Hessian 

 Ely Not Imported from Europe" (Canadian Entomologist, October, 

 1880). His claim that the yeast fungus, when sprinkled upon injuri-
