logy. For many years he was keeper of the Entomological 
Department of the Berlin Natural History Museum, and 
also a Professor of Zoology in the University of that city. 
About the year 1876, difierences with the then Director of 
the Museum induced him to resign his appointments at 
Berlin, and he subsequently accepted the Professorship of 
Zoology at Greifswald, which he held until his death. 
Gerstacker was an industrious and thorough worker in all 
departments of entomology. His published papers at the 
time of his death were very numerous. Amongst his 
principal works may be noticed a " Monographie der 
Endomychiden " (1858) ; the Arthropoda in the Hand- 
buch der Zoologie " (1863); and the Arthropoda in 
Bronn's " Klassen und Ordnungen der Thier-Reichs," 
but this latter, which was commenced in 1866, proceeded 
very slowly. In 1873, he published a memoir entitled, Zur 
Morphologic der Orthoptera-amphibiotica," a term employed 
by him to include those pseudo-neuropterous families in 
which the early stages are aquatic. 
William Henky Tugwell died after a long illness at 
Lewisham, near London, on September 20th last, aged sixty- 
four, from spinal disease which had confined him to his room 
for many months. His name as an entomologist is familiar 
to all British Lepidopterists, and his collection of Macro- 
Lepidoptera was one of the finest in existence, rich in species 
and especially in varieties. His earlier writings are chiefly 
contained in the pages of the " Intelligencer," and subse- 
quently in the " Entomologist," and " Entomologist's 
Monthly Magazine." He will be missed at the South 
London Society, of which he was at one time President. 
Claudius Key. This industrious French entomologist, 
who, in conjunction with the late Etienne Mulsant, was a 
prolific writer on Coleoptera and Hemiptera, died last year. 
C. Rey joined the Entomological Society of France in 1887, 
and had recently been elevated to the rank of Honorary 
Member of that Society. He was President of the Societe 
Frangaise d'Entomologie from the time of its foundation in 
1882. He resided at Lyons, and most of his memoirs 
appeared in various publications in that city.
