VI A BIOGRAPHICAL NOTICE OF 



number of his later writings. The Proceedings of the Entomo- 

 logical Society of Philadelphia record the reception of a letter 

 written from Camp Independence, July 1, 1863, giving an account 

 of his researches on insects in that region. 



He tells us elsewhere*': " I went to North-eastern California, near 

 the head waters of Pit River — a tributary of the upper Sacramento. 

 Near Fort Crook I saw the first living specimens [of Amphizoa in- 

 solens'\, though so rare and diflScult to be obtained, that I was satis- 

 fied with the securing of a few specimens, without risking the loss 

 of any in the observation of their habits. From Fort Crook I went 

 to Surprise Valley, on the boundary line between California and 

 Nevada. Here I found them very abundant, as well as on the 

 western slope of the Sierras, in the creeks forming the three head 

 branches of Pit River." Other places he mentions as having visited 

 are Yuma, Gila Bend, Maricopa desert, Temescal and Fort Grant, 

 in Arizona. 



He returned to Philadelphia in 1866, was elected President of the 

 Entomological Society December 10th, and, on December 26th, pre- 

 sented to the Academy the first of his results " accumulated during 

 a four years' residence in California and the adjoining territories."* 

 The long series of papers on the Coleoptera, destined to appear for 

 nearly thirty successive years, was thus begun, while at the same 

 time he commenced to build up a growing and successful practice in 

 medicine, more especially in obstetrics. A note-book, in his own 

 handwriting, entitled, "Obstetric Memoranda," records the cases he 

 attended at a later period, and it may be of interest to quote the 

 totals for each year to indicate the extent of his practice : 1879 28, 

 1880 31. 1881 37, 1882 26, 1883 31, 1884 33, 1885 58, 1886 55, 

 1887 20 in the first six months, and then the record ends. 



In the Spring and Summer of 1874 he paid a visit to Europe, 

 was at the meeting of the Entomological Society of London on 

 June 1st, examined the collections of the British Museum, spent con- 

 siderable time in Paris, where he is recorded as having attended the 

 meetings of the Entomological Society of France on July 8th and 

 22d, August 26th and September 9th, and made the acquaintance 

 of many European entomologists. 



A second and a third visit to Europe were made in the summers 



of 1882 and of 1888 respectively. In the former year he was with 



Westwood in Oxford, and Dr. David Sharp in Scotland ; in Paris, 



. where his name appears in the minutes of the Entomological Society
