AND NOMENCLATORS. XXXV 



editor of The Zoologist, a Miscellany of Natural History, 

 at once popular and scientific : this periodical has run 

 a prosperous career for sixteen years, and is doubtless 

 known to every one of our readers. 



NICELLI, Graf G. von, of Berlin, author of the " Bericht iiber 

 die Pommerschen Arten der Gattung Lithocolletis " in 

 the Stettin Entom. Zeitung for 1850 : a complete mono- 

 graph of the same genus is promised. 



NYLANDER, Dr., late of Helsingfors, many of whose obser- 

 vations are recorded in Tengstrom's "Finland's Fjaril- 

 Fauna," is the author of papers in the Annales de la Soc. 

 Ent. de France (1854), and Ann. Nat. Hist., and of a 

 recent work on the Ants of France and Algeria. 



OCHSENHEIMER, Ferdinand, born at Mainz in 1767; on the 

 completion of his academical career was employed as 

 private tutor in several families at Mannheim. At that 

 time the theatre of Mannheim was one of the first in 

 Germany, and still preserves a creditable reputation. 

 Ochsenheimer wrote several comedies, which were pro- 

 duced with great applause ; and this seems to have drawn 

 his attention still more closely to the stage, for in his 

 twenty-seventh year he resolved himself to become an 

 actor : this resolution he carried out, and for some years 

 was a chief attraction at many of the principal theatres 

 of Germany ; his performance of " Talbot " in " Die 

 Jungfrau von Orleans " called forth the warmest en- 

 comiums of Schiller. It was about the end of last cen- 

 tury that Ochsenheimer began to collect insects, and 

 make the acquaintance of other entomologists, Treitschke 

 among the rest; in 1802 he formed a friendship with 

 Laspeyres, who urged him to become an author ; and in 

 1805 the first volume of a Natural History of the Moths of 

 Saxony appeared at Dresden. Differences with his pub- 

 lisher caused him to desist ; and thereupon he began his 

 more extensive work, " Die Schmetterlinge von Europa," 

 the first part of which was published at Leipsic in 1807. 

 Ochsenheimer's fame was at once established; he was 

 soon elected into the Soc. of Naturalists at Berlin, and 

 subsequently into those of Wetterau and Halle. Pro- 

 fessional engagements and entomological pursuits formed 

 a double bond of union between Ochsenheimer and 

 Treitschke: they collected together, and their life was 

 divided between the stage and insect-hunting; thus 

 Treitschke became associated with his senior in the pro- 

 duction of the great work, and survived him to complete 

 it. One night, after performing at the theatre at Vienna,
