In contrast to this change, those crocodiles which were adapted 
to a warm-blooded diet survived until the Miocene Period, and 
only retired to the tropics when the climate became so cold that 
the palms vanished out of Europe.

The following communication was read :— 
‘Oligocene Mosquitoes in the British Museum, with a 
Summary of our present Knowledge concerning Fossil Culicide.’ 
By F. W. Edwards, B.A. (Communicated by the Secretary 2) 
The material dealt with in this paper is in part the property of 
the Geological Department of the British Museum, and in part 
belongs to Mr. R. W. Hooley, F.G.S. The study of it was under- 
taken’ by the Author at the suggestion of Prof. T. D. A. Cockerell, 
and by permission of the Keeper of the Department. All the 
specimens are from the Oligocene of the Isle of Wight. 
The result of the study confirms what was already known of the 
Oligocene Insect-fauna. The genera appear to be inseparable 
from those living at the present day, and the indications supplied 
by some of the species suggest a fauna similar to that of the 
Ethiopian and Oriental regions at the present day. 
No light is thrown by the fossils on the phylogenetic history of 
the Culicide, nearly all the recent types being represented in the 
Oligocene fauna, and no peculiar forms occurring. ‘The genus 
Anopheles, however, has not been found, probably. because of its 
comparative rarity. 
The three species described from the Oligocene of the Isle of Wight 
by Prof. Cockerell are discussed in detail, and are referred to the 
genus Aedes in the broad sense. ‘Two new species, one of Culex 
anil one of Tenior hyneh us, are described. 
A critical summary is given of our present knowledge of fossil 
Culicide. No fossil that can be positively referred to “this family 
is yet known from the Mesozoic.

A Correction. By Lord Roruscuitp, F.R.S. 
In my article in the May number of this Magazine on the Arctiinz 
of Para, I described a new species under the name of Ltobinsonia 
mossi on page 486, quite overlooking the fact that I had already 
given this name to another species on page 458, I therefore 
rename the species on page 486 Robinsonia milese,
