WORK IN THE UNITED STATES

an earlier journey in 1852-1853. In Berlin I had a long and inter¬ 
esting interview with Alexander von Humboldt in his house, but 
our conversation had little to do with entomology. Although 
eighty-seven years old at that time, and much bent by age, he 
was remarkably active, both physically and mentally. 
In the course of my further journey, I visited Winnertz at 
Crefeld (with whom I had corresponded before), Baron de Selys 
Long champs, Candeze, and others in Belgium, van der Wulp, 
Snellen van Vollenhoven , etc., in Holland. In London I made 
(and in part renewed') acquaintance with the principal entomolo¬ 
gists, some of whom I remembered having met before during a 
visit to England in 1852 ( Westwood , Stainton , Francis Walker , 
Adam White , etc.). In the beginning of June I embarked at 
Liverpool on the steamer “ Arabia,” and landed in New York after 
a passage of thirteen days. 
II WORK IN THE UNITED STATES (1856-1877) 
The second period of my entomological career embraces the 
twenty-one years of my residence in the United States (1856-1877), 
during which, until 1862, I was Secretary of the Russian Legation 
in Washington; in that year I was appointed Consul General of 
Russia in New York, which thus became my residence between 
1862 and 1871. I resigned my post in 1871 and made several 
journeys to Europe and back, until, in the autumn of 1873 (this 
time as a private citizen), I again settled in the United States, 
where I remained till 1877. These twenty-one years were, as 
regards entomology, principally devoted, in collaboration with 
Dr. H. Loew , to the task of working up the Biptera of North 
America north of the Isthmus of Panama. A great deal of my 
time, as will be seen, was spent in acting as a purveyor of ma¬ 
terial for Loew to work upon, and as a translator and editor of his 
manuscripts. 
Hermann Loew , born (1807) at Weissenfels, Prussia, was Professor in Posen 
about 1840, Director of the “ Realschule ” in Meseritz (Posen) from 1850 to May, 
1868, and finally lived in retirement at Guben (Saxon Prussia) from 1868 up to 
the year of his death. A translation of a sympathetic biography of Loew, by his 
political friend Dr. Ernst Krause (known in literature under the pseudonym of
