hin 
separate form. He was also a constant contributor to German 
entomological periodicals. He was one of the few Entomologists 
who devote themselves, almost exclusively, to a study of the 
habits and economy of known insects rather than to the deserip- 
tion of new ones; and will always be remembered by the 
Coleopterist for his elaborate researches into the Natural History 
of the Xylophagous beetles. 
On the 18th of December last, Von Heinemann of Brunswick 
died suddenly. His work on German and Swiss Lepidoptera is 
well known, and he was engaged in correcting the proofs of the 
concluding portion at the time of his decease. 
Dr. J. P. Rambur died at Geneva on the 10th of August, 1870, 
aged 69. When a young man heexplored the Entomology of 
Corsica and Andalusia, and in 1842 commenced publishing an 
expensive Entomological Fauna of the latter country, but the 
issue was soon discontinued. In the same year appeared his 
chief work, the volume on Neuroptera, in the ‘Nouvelles Suites a 
Buffon.’ He tells us in his preface to this work that the Lepi- 
doptera were his favourite study, while the Neuroptera were, of 
all insects, the least attractive to him; yet the task so inauspiciously 
undertaken was executed in a manner which proves him to have 
been a true Entomologist. He paid great attention to structural 
details, and especially to secondary sexual characters, which 
have since been found so valuable in the classification of other 
orders of insects. He laid the foundations of the modern classifi- 
cation of the Neuroptera, and, in so doing, made a real advance 
in the study of Entomology. He was one of the founders of the 
Entomological Society of France. 
Dr. Emeric von Frivaldszky of Pesth, a Hungarian Entomolo- 
gist and traveller, died during the year 1870, aged 72. He was 
more especially known by his investigations of the Entomological 
fauna of the Balkan Mountains, and of Asia Minor. He published 
several memoirs on the results of his expeditions, but many of 
these are in the Magyar language, and remain as sealed books to 
most Entomologists. Latterly he industriously investigated the 
cave-beetles of his native country. 
The Entomological literature of the year possesses many 
features of interest, and I propose to notice a few of the more 
remarkable works I have met with; after which I shall beg to
