Coleoptera for the ' Zoologischer Jahresbericht,' to which I shall 

 have occasion to refer later on in this Address. In 1877, possibly 

 in an unlucky moment, he accepted a position in the Entomological 

 Department of the Berlin Museum, as successor to Dr. Gerstacker, 

 who had resigned. A letter written by him to an English friend 

 at tliat time shows that he entered upon his duties with no light 

 heart, and that the chief inducement consisted in the facility for 

 reference to the vast stores of that establishment. I believe there 

 was no necessity whatever for his seeking such a position as a 

 source of income. His tenure of office was brief; the letter referred 

 to explains why he accepted office, but the reasons for his early 

 resignation I know not. By profession Von Harold was a soldier, 

 and, as an officer of the Royal Guard of Bavaria, he saw active 

 service in the Austro-Prussian war of 1866, during which cam- 

 paign he received a very severe wound at the battle of Kissingen. 

 Wilhelm Auguste Jules Lichtenstein died at Montpellier on the 

 30th November last, aged 68. He became one of us in 1876. 

 In the summer of last year it was known in this country that he 

 had been disabled by a paralytic stroke. Lichtenstein was, I 

 think, a direct descendant of the German naturalist of the same 

 name who published a good deal on Entomology, and some of 

 whose papers appeared in the ' Transactions ' of our Linnean 

 Society quite at the end of the last, and beginning of the present, 

 century. He was related by marriage to M. Planchon, the well- 

 known Professor of Botany at Montpellier. If I mistake not he 

 was for some time resident in this country ; be that as it may, his 

 knowledge of our language was perfect ; the numerous notes 

 and papers he published here were not translations. Lichtenstein 

 appears to have published nothing on Entomology until he was 

 about fifty years of age ; his first paper saw the light in 1869. 

 He was a vineyard proprietor in the South of France, but I think 

 he retired from active business-life just about the time the 

 Phylloxera appeared in France. Indeed, it is very probable the 

 Fhylloxera largely determined his careei- as aii entomologist : he 

 studied the insect thoroughly, and, in connection therewith, the 

 Apliides generally, and most of his very numerous writings sliow 

 that his bias lay distinctly in the direction of solving problems 

 concerning the life-histories of Aphides, Coccidce, Psyllida, 

 Cyn'qyidcn, and others, in connection with the plants they attack. 

 The complex life-cycles of Apludes were especially studied by him,
