 South Wales, with References to those of other parts of Australia, l'art I. 

 Bj R. Etheridge, Junr., and John Mitchell. The authors give an epitome 

 of our previous knowledge of the Proetidae in Australia ; discuss the general 

 question of the genus ; and describe three species, two of which were previ- 

 ously known, viz., Proetus boivningensis , Mitchell, P. Rattei, E. &M., and 

 P. auslralis, E. & M. The characters of the three species are given at length, 

 their relations one to the other, and finally with those of other countries. — 

 4) Observations on the Chlor aemidae, with special Reference to some Austra- 

 lian forms. By Professor W. A Haswell, M.A., D.Sc. This paper has re- 

 ference chiefly to a remarkable member of the family which occurs on the 

 Queensland coast ; but the opportunity has also been taken to give some 

 account of two other undescribed Chloraemids obtained by the author in Port 

 Jackson. — Mr. Froggatt exhibited some living beetles (fam. Curculionidae), 

 which afford a good example of protective coloration. They were found a 

 few days since at Wellington, N.S.W.,. on the trunks of Kurrajong trees 

 [Sterculia) , the bark of which they resemble so closely in tint and general 

 appearance that it was quite by accident he first recognised their true cha- 

 racter.
