IV PROCEEDINGS OF THE 



Notes on the habits and description of a new Australian species 

 of Oiketicus. By W. W. Saunders, Esq. 



Mr. Westwood brought before the notice of the Society a recent 

 publication on the potatoe disease by Mr. Smee, in which the 

 disease is exclusively attributed to the attacks of a species of 

 Aphis. This subject he considered as one of too great import- 

 ance to allow such a fallacy to be disseminated without being 

 checked ; the well known nature of the operations of the Aphides 

 on other plants being of a totally different kind from the potatoe 

 disease, whilst the facts which have been recently observed, of the 

 occurrence of the disease without the presence of a single Aphis, 

 completely disproved a theory which its author is nevertheless 

 endeavouring to promulgate with unceasing pertinacity. Mr. 

 Westwood's statements and opinions were supported by the 

 remarks of the President as well as by Messrs. J. F. Stephens and 

 E. Doubleday.
