His entomological work was concerned almost exclusively with 

 the Coleoptera, his first paper being entitled " Descriptions of 

 Some New North American Species in the Cabinet of the Ento- 

 mological Society of Philadelphia." published in the "Proceed- 

 ings of the Academy of Natural Sciences of Philadelphia,' in 

 i860. Seven species new to science were described and figured. 

 In all over one hundred and fifty papers were contributed to the 

 proceedings and transactions of learned societies, his last contri- 

 bution being an important one on the Coleoptera of Baja Cali- 

 fornia, published in the "Proceedings" of the California Academy 

 of Sciences for 1895. 



After the death of Dr. John L. LeConte in 1883, Dr. Horn, 

 who was a worthy successor, was elected President of the Amer- 

 ican Entomological Society and Director of the Entomological 

 Section of the Academy of Natural Sciences. These two offices 

 he held at the time of his death. He was Professor of Ento- 

 mology at the University of Pennsylvania since 1889, Dut did not 

 teach or lecture there, the position being an honorary one. 



Among scientific bodies the following may be mentioned as 

 having conferred special honors on him. He was elected a corre-

 1893; an honorary member (one of twelve) of the Entomological 

 Society of Belgium; an honorary member (one of ten) of the 

 Entomological Union of Stettin; an honorary member (one of 

 eleven) of the Entomological Society of France, of the Russian 

 Entomological Society, and of the Feldman Collecting Social 

 of Philadelphia. At its commencement in March, 1897, tne 

 Western University of Pennsylvania, at Pittsburg, conferred on 

 him the degree of Sc. D. He was a Secretary and Librarian of 

 the American Philosophical Society (Philadelphia) at the time 

 of his death. In 1866 he joined the Academy of Natural Sciences 

 of Philadelphia, held the office of Corresponding Secretary for 

 fourteen vears, and was a member of the Council and of the 

 Finance and Publication Committees for long periods of time. 



Dr. Horn was a patient and untiring worker, and his loss will 

 be keenly felt in the institutions in which he served as an officer 

 so long and efficiently. The entomological world has lost a 

 shining light and American Coleopterology its greatest votary. 

 As a systematic coleopterist he probably did not have a superior
