26 THE ENTOMOLOGIST. 



some particular group or family of insects, he decided that he 

 would study only the phytophagous beetles. Thus it was that 

 he formed an extensive collection of, and became the acknow- 

 ledged authority on, this group of the Coleoptera. It would be 

 difficult to estimate, even ajDproximately, the large number of 

 species, procured from all parts of the world, that he has made 

 known to science. 



Besides numerous papers published in the * Proceedings of 

 the Zoological Society,' ' Transactions of the Entomological 

 Society of London,' and in the organs of various learned societies 

 abroad, he was the author of two volumes on Phytophaga in 

 ' Biologia Centrali Americana,' and had just completed a volume 

 on the same group of insects for the * Fauna of India.' The 

 latter work he had seen through the press, but unhappily was 

 fated not to see it published. 



Ever willing and eager to assist in the identification of those 

 insects he understood so well, and of which he had such expert 

 knowledge, he had determined, and where needful described, the 

 phytophagous material in the principal museums and private 

 collections of the world. 



Mr. Jacoby was elected a Fellow of the Entomological Society 

 of London in 1886, and he was also a member of several Zoological 

 and Entomological Societies on the Continent. For many years 

 past he was a welcome guest of the Entomological Club, at the 

 annual supper given by Mr. Verrall, and on these occasions he 

 contributed greatly to the pleasure of the evening by his beauti- 

 ful violin solos. His many amiable qualities endeared him to 

 those with whom he came in contact, in the scientific as well as 

 in musical spheres, and his departure will be deeply regretted 

 by many who have lost a good friend. He leaves a widow, two 

 daughters, and a son.
