 alluded to many interesting points in the economy of these

 Victorian Alps." The author gave a few notes on several of the 

 species of lichens collected by him at Mt. Hotham, &c., during

 vancement of Science. These numbered nearly forty varieties, eight 

 of which were new to Victoria, and one, Siphula muelleri, Wilson, 

 named after the president of the association, was new to science.

NOTES ON THE RUTHERGLEN FLYING-BUG PEST. 

 By C. French, F.L.S., Government Entomologist, Melbour e. 

 ( Read before I<ield Naturalists' Club of Victoria, \oth Feb., 1890.^ 



It is my intention to offer a few remarks on the subject of the 

 so-called " Rutherglen fly-pest." I intend being brief, as it may 

 be said with truth that the present notes are more suitable for 

 meetings of the Horticultural Societies, Vinegrowers' Associations, 

 or Farmers' Clubs than for a meeting of the Field NaturaHsts' Club. 

 I think, however, that some short account of the insect in question 

 and its doings cannot fail to be of some interest to the members 

 of this club.
