GEORGE HENRY HORN. XV 



institution for many years. Other papers are contained in the Pro- 

 ceedings of the American Philosophical Society, of which, also, he 

 was a Secretary and Librarian at the time of his death. 



In the latter part of 1889, when the Entomological Section of the 

 Academy of Natural Sciences and the American Entomological 

 Society decided to establish a monthly journal devoted to their 

 specialty, the weight of Dr. Horn's authority was naturally desired 

 to aid the new enterprise. His name consequently appeared on the 

 cover of the first number of "Entomological News" (January, 

 1890) and the contents included a short synonymical article on 

 Cri/ptohypnus from his pen. Later issues contained short papers on 

 variation, as that on " Trichodes ornatus Say" (Jan'y, 1891), which 

 was evidently intended as a warning to those disposed to rush into 

 print with descriptions of new species based on color differences, and 

 those on variations in Cicindela (Feb'ry, 1892), to which we shall 

 again refer, in Dorcas (April, 1892), and in Amblychila (November, 

 1893), Each of the first seven volumes contains some brief contri- 

 butions from him, and the proceedings of the Entomological Section 

 and Society published therein afford glimpses of his entomological 

 studies from month to month. Finally, the " News " contains what 

 seems to be his very last Coleopterological note — of six lines only — 

 dealing with the synonymy of some North American Buprestids, 

 and which appeared in October, 1896. 



In describing the relations of LeConte and Horn Prof. Smith 

 says : " At first there was some friction between him and the younger 

 man, who was very positive in many cases where the older, more 

 experienced student was inclined to be conservative. . . . Dr. Le- 

 Conte was by all odds the broader man ; his knowledge of nature 

 at large was much wider, and he saw his speciality, the Coleoptera, 

 much more truly in their relation to the other orders of insects, and 

 this class in its relations to the rest of the animal kingdom. Dr. 

 Horn was much more completely a specialist, with little interest 

 outside the Coleoptera, but in this knowledge of detail was infinitely 

 greater." These characteristics, and especially the latter, he retained 

 throughout life. Little of general interest to the zoologist is to be 

 found in his writings. Upon some few general topics, nevertheless, 

 he did touch, and to his statements on these we shall devote some 

 space. Prof. Smith is probably correct in stating that " His mono- 

 graphic and revisioual papers are almost all built with the evolu- 

 tionary idea constantly in mind" (Science).
