as well. He was an excellent collector and his cabinet was unusually 

 rich in Californian and Pacific coast forms. This collection remains 

 in New York, and forms the nucleus for the lepidoptera in the collec- 

 tion of the American Museum of Natural History. 



Dr. George D. Hulst was one of the Brooklyn entomologists and 

 devoted his energies to work in the lepidopterous families Geometridse 

 and Pyralididse. "While his systematic work in these groups is most 

 useful, it is not equal to his personal influence upon those that were 

 fortunate enough to come into contact with him. I grew to love that 

 man and felt his death as a personal loss. His collection is now in my 

 charge at Rutgers College, to which institution it was given by him 

 before his death. 



Dr. Herman Strecker, of Reading, Pa., was known to many of 

 our older members, and never were there more diverse judgments than 

 those passed upon him. But he was earnest if erratic, and succeeded 

 in accumulating an enormous collection of lepidoptera during his long 

 life. He would pay any price for a specimen that he wanted, and halt 

 at no expedient to secure what he could not buy. He was a genius 

 with pen, pencil and chisel; a sculptor of mortuary emblems by pro- 

 fession, and a painter of butterflies by choice. His publication on this 

 subject was unique : all the drawings and engravings were made by 

 him, and all the plates were hand colored. His industry was con- 

 tinuoiis and he was tireless in his work. His writings were spicy and 

 he never hesitated in printing what he wanted to say : he was his own 

 publisher and had none to say him nay. His collection is now in the 

 Field Museum in Chicago. 



In the tineid families of the Microlepidoptera there was an im- 

 mense untilled field which only one of the older American students had 

 the courage to undertake. To Brackenridge Clemens belongs the honor 

 of breaking ground in this series, and upon his work the subsequent 

 students in the group, whom fortunately we yet number among • our 

 associates, have built their own. Clemens also did some work in the 

 macros, notably the Sphingidae, and many of his types are yet to be 

 found in the collections of the American Entomological Society. 



Among the unique figures in American entomology none looms 

 larger than Dr. H. A. Hagen, of Cambridge. Big, ponderous, thor- 

 oughly German to the end of his life, intensely loyal to his chief and 

 his work, he was easily the most learned entomologist of his day. 

 His monumental work in the literature of entomology has proved a 

 gold mine for later students, and would alone have been considered 

 a creditable life work. But Dr. Hagen was also a special student in 

 the Neuroptera, and his volume in the Smithsonian series is essential 

 to every student in the order to the present day. I knew Dr. Hagen 

 well and was his guest at times. I won his heart by the meekness with
