GEORGE HENRY HORN. 



The Entomolog-ical Society of Philadelphia, founded by Ezra T. 

 Cresson, James Ridings and George Newman, had been organized 

 February 22d, 1859, and of this association Horn became a member 

 July 23d, 1860. Dr. John L. LeConte, then the foremost A nerican 

 coleopterologist, had been one of the organization members, but 

 Horn, although frequently and not incorrectly styled the pupil of 

 LeConte, does not appear to have made LeCoute's personal acquain- 

 tance until after his own work on insects had begun. Mr. Charles 

 Liebeck states that Dr. Horn once told him that the occasion of his 

 first meeting with LeConte was the publication by Horn^ of the de- 

 scription of Margarinotus guttlfer ; this attracted LeConte's atten- 

 tion, caused him to seek out Horn, and so the foundation of their 

 long friendship was laid. The first fruits of Horn's connection with 

 the Entomological Society soon appeared in " Descriptions of new 

 North American Coleoptera, in the Cabinet of the Entomological 

 Society of Philadelphia" presented to the Academy of Natural 

 Sciences December 18th, 18(J0, and published in the Proceedings 

 for that year, pp. 569-571. This, his first entomological pape^'r, 

 describes seven new forms, the first being Nomaretus imperfectus from 

 Hampshire County, Virginia. 



In the meantime the Civil War had broken out. On the ninth 

 of June, 1862, he resigned as a member of the standing committee 

 of the Society on Coleoptera, to which he had been elected Decem- 

 ber 9th, 1861, and went to California. Under date of February 

 26th, 1863, he was commissioned, by Governor Leland Stanfi)rd, 

 Assistant Surgeon in the Second Cavalry, California Volunteers, and 

 took the oath of allegiance at Camp Independence, Owen's Valley, 

 California, March 1st, 1863. On July 14th, 1864, he became surgeJn' 

 of the First Infantry Regiment, California Volunteers, " remaining 

 in that position until the term of service of the regiment expired, 

 December 3rd, 1864." Under date of May 18th, 1865, he was com' 

 missioned Assistant Surgeon, with rank of First Lieutenant, in the 

 Second Cavalry again, and took the oath at San Francisco, May 

 22nd. August 26th, 1865, his commission as Surgeon in the Second 

 Infantry Regiment, California Volunteers, with rank of Major, was 

 signed by the Governor, and subscribed to by Horn at San Fran- 

 cisco, September 23d, 1865. "His service terminated with that of 

 the stafl" of his regiment April 16th, 1866." 



These years in the West gave him many opportunities for the 

 collecting and observing of insects, and allusions thereto occur in a 



TRAXS. AM. KXT. SOC. ^PKIL, 1898.
