230 Entomological Society. 



Mr. Gutch exhibited several boxes of Coleoptera from Central 

 Europe, 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 Tenebrionida. 



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.

The following memoirs were read : — 



A note from Mr. Long of Dover, on an attempt to naturalise 

 Palingenia Virgo (a continental species of Ephemerida remarkable 

 for its snow-white wings) by bringing over the ova in a bottle filled 

 with 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 

 observed between Boulogne and Calais a few days after the 5th of 

 July. .
