Entomological Society. 
Mr. Gutch exhibited several boxes of Coleoptera from Central 
Eurojoe, and a new species of Fritillary butterfly from Servia. He 
also presented to the Society a quantity of specimens of Simulium 
Columbatchense, a small dipterous insect which attacks the cattle in 
the Bannat, frequenting all the moist parts of the body, as the nos- 
trils, anus, &c., and causing the death of great numbers of these 
animals. They occur on both banks of the Danube, appearing in 
clouds, and are supposed by the common people to be bred in a hole 
in a mountain where the body of the dragon slain by St. George 
was deposited. 
Mr. Westwood exhibited a small box of Coleoptera from Western 
Tropical Africa, including numerous rare TenehrionidcB. 
Mr. W. W. Saunders exhibited a small box covered with the cases 
formed by the larvae of an Australian species of Oiketicus, and inclu- 
ding a number of specimens illustrating the natural history of six 
species of that genus, sent from the interior of New South Wales by 
Mr. Stevenson.

A note from Mr. Long of Dover, on an attempt to naturalise 
Palingenia Virgo (a continental species of Ephemeridee remarkable 
for its snow-white wings) by bringing over the ova in a bottle filled 
v/ith the water of the Rhine where they occur, and by placing them 
in the rivers in England. It did not appear that the experiment had 
been successful. Also further notes on swarms of white butterflies
