PROCEEDINGS OF SOCIETIES. 
52ND MEETING OF GERMAN NATURALISTS 
AND PHYSICIANS IN BADEN-BADEN. 
WE findin the Extomologische Nachrichten 
for 1 April 1880, Jahrg. 6, p. 65-79, a notice 
of the meeting entitled above, by M. von 
Hopfigarten, of Miilverstedt. The Entomo- 
logical section of this meeting, now four 
years old, is declared to be the centre of 
German entomological life. After some ir- 
relevant matter, and a list of the eighteen 
persons present, a list is given of the com- 
munications presented. Dr. von Heyden, of 
Frankfort, mentioned that Tournier had 
found a species of Laccobcus, which he named 
thermaritus, in a hot spring, of temperature 
474-49° C., in Baden, Switzerland. Mr. 
K6ppen, of St. Petersburg, called attention 
to a bibliography of the zoology of Russia 
which he had published in German. Baron 
von Osten-Sacken, now of Heidelberg, spoke 
of ‘‘Certain remarkable cases of the geo- 
graphical distribution of ¢¢pulidae,” an ab- 
stract of which communication is given as 
follows : — 
Five species of the genus Ptychofpiterina are 
known; one is found in the Atlantic states 
of North America, one in California, one in 
Chili, one in New Zealand and one in amber, 
The genus Elephantomyia is found in the 
Atlantic states of North America, in Califor- 
nia, and in amber. The genus Prochobola 
is known from northern and middle Europe, 
North America, New Zealand, Van Dieman’s 
Land and South Australia. Several species 
of the group axdsomerina with enormously 
long antennae in the males occur in the 
Atlantic states of North America and similar 
species are still found in amber. The rather 
frequent contact of the [eastern] North 
American fauna with that of the amber, on 
the one hand, and that of California, Chili 
and Australia, on the other hand, is especially 
worthy of note, as is also the circumstance 
that in certain genera of diptera sporadic 
occurrence is more frequent than it is in 
the other orders of insects. Considerable 
discussion followed this communication, in- 
volving the question of the geographical 
distribution of cave-insects. 
Several ingenious pieces of collecting ap- 
paratus were exhibited, and methods of cap; 
ture were discussed. Five sessions were held. 
Baron von Osten-Sacken proposed that a 
loan-library should be formed, for the benefit 
of entomologists, from which any one might 
obtain books without fee. He offered, in 
case such a library were established, to pre- 
sent to it about 300 works treating of diptera, 
mostly. separates. Dr. Noll, of Frankfort, 
said that such a library, containing works on 
malacozoology, had already been established 
at Frankfort-on-Main, and that it would be 
a good plan to choose that city for the /ocale 
of this new library. This, together with 
other propositions that were brought forward 
at the final session, was referred to the meet- 
ing to be held in 188o. 
A notice is given further of collections ex- 
amined and excursions made, and the author 
concludes with an expression of exultation 
that the entomologists felt strong enough to 
resist the attempt of the zoologists to swallow 
their section. 
It was determined to hold the next meeting 
18-24 Sept. 1880, in Danzig. Bick eiVh.
