1899] ENTOMOLOGICAL NEWS. 81 



R. Crotch was at that time working at Cambridge, as was also Mr. 

 E. A Schwarz, who became hisinstnictor in methods of collecting. 

 During the winter of 1873-4 Messrs. Hubbard and Schwarz sys- 

 tematically investigated the hibernating quarters of the Coleoptera 

 near Cambridge, turning up species theretofore undreamed of, in 

 utterly unheard of numbers. Mr. Hubbard's share of this became 

 the property of the Cambridge Museum, and is known as the 



"Winter Collection." 



The triendship tbrmed between Messrs. Hubbai"d and Schwarz 

 during this period was based upon mutual esteem and admiration 

 on the part of each of qualities not possessed by the other, and it 

 lasted without break to Mr. Hubbai-d's death. 



In the summer of 1874 they collected near Detroit, Mich., which 

 was Mr. Hubbard's home, and at this time the Detroit Scientific 

 Association was organized, with the view of getting up a local col- 

 lection of Natural History and other specimens in time forthe meet- 

 ing of the A. A. A. S., which was to he held in 1875. 



During the winter of 1874-5 Mr. Hubbard collected in Florida, 

 returning in time to get all the material in shape before the meeting 

 of the Amei'ican Association, then under the presidency of Dr. 

 John L. Leconte An unusual number of the woi'king entomolo- 

 gists of the country attended this meeting, of whom Dr. Leconte 

 and the Messrs. Grote, Lintner, Osten-Sacken and Riley, became 

 the guests of Mr. Bela Hubbai'd, the father of Mr. H. G. Hubbard. 



The little ouJ building in the Hubbard grounds, containing the 

 collection of insects, immediately became a centre of interest, the 

 material there stored being unpai-alleled for wealth of specimens 

 and with so many new forms that Dr. Leconte declared that it 

 made it necessary to re- write part of his "Classification." Here 

 was formed that personal friendship with Dr. Leconte which lasted 

 to the death of the latter, and no better correspondents did Dr- 

 Leconte ever have than the Messrs. Hubbard and Schwarz 



In 1876-77 our collectors investigated the Lake Superior region, 

 and made the phenomenal collection which formed the basis of the 

 paper published by Dx*. Leconte, in April, 1878. 



In 1879 Mr. Hubbard was engaged as the naturalist of the State 

 Geological Survey of Kentucky, under Prof. Shaler, and among 

 other matters explored the Mammoth Cave, making known its 

 peculiar fauna of blind insects. 



Becoming possessed of a piece of land near Crescent City, Florida, 

 in 1880, he devoted himself for a time to the horticultural interests 

 of that State, continuing indeed to the time of his death. 



In 1881 he was engaged as a special agent for the Division of En- 

 tomology by Dr. C V. Riley, working tirst on cotton insects, and 

 afterwai'd on those injurious to the orange: the results of the latter 

 study being published as a bulletin of the department in 1885. It 

 was in the coui^se of this work that he discovered and perfected a 

 practical method of emulsifying kerosene so as to allow its dilution 

 with water for insecticide purposes.
