 sident, in the Chair. 



The President announced the safe arrival of W. S. Macleay, Esq., 

 and his collections in New South Wales, and his intention to publish 

 descriptions of various remarkable Australian groups. He had as-

 ing their relation with the Uranice, as suggested in his memoir in the

Mr. Westwood announced the capture of a species of Cerapterus 

 (but forming a separate subgenus) near Rio Janeiro, all the other 

 species of the family Paussidte being inhabitants of the old world. 



Mr. Waterhouse exhibited some remarkably small specimens of 

 Garden white butterflies, captured in Devonshire, but very confined 

 in their locality. 



The President exhibited specimens of Goliathus torquatus $ , Eu-

 Sierra Leone ; also a new species of Adelotopus and another genus 

 allied thereto, with other insects from New Holland. 



Mr. Westwood exhibited a living specimen of Clerus alvearius, 

 which he had recently reared from a nest of Osmia muraria, brought 

 by him from France two years and a half previously. 



The following memoirs were read : ♦
