NOTES AND EXHIBITS. 



Mr. Etheridge exhibited the fossils described in his paper. 



Mr. MacDonnell exhibited under the miscroscope mounted 

 specimens of a mayfly of the genus Baetis, the males of some 

 species of which have two pairs of compound eyes, one pair in the 

 position ordinarily occupied by the compound eyes of flies, the 

 other or extra pair being on peduncles or turrets. The specimens 

 exhibited were found in a cobweb near Adelong, N.S.W., and 

 mounted by Mr. H. Sharp. 



Mr. A. Sidney Ollifi" exliibited (1) specimens of Ejjicrocis 

 terebrans, Oil., (family Phycitidse), from Gosford, Brisbane Water, 

 a new moth which has done considerable damage to the red cedar 

 trees {Cedrela toona, Roxb.) in the State Forest Nursery at that 

 place, by burrowing in tlie larval state into the main stems or 

 " leaders " of the trees ; (2) a specimen of Adela, evidently a new 

 species, captured at Kangaroo Mt., Broughton Creek, N.S.W., 

 in April last. The only recorded Australian representative of 

 the genus, Adela aethiops, R & R., is very difierent, as far as can 

 be judged from Folder's figure in the " Reise Novara," as it has 

 the forewings ornamented with three distinct transverse fasciae ; 

 and (3), on behalf of Mr. R. Helms, a species of Synemon (family 

 Castniidse), from Benalla, Victoria, showing a remarkable dis- 

 parity in the sexes in form, marking, and colour. 



Mr. Thomas exhibited specimens of petroleum shale from Joadja 

 Creek, N.S.W., coated with botryoidal or mammillated iron pyrites. 



Mr. Norton exhibited the larva of Melolontha sp , infested with 

 a fungus, probably a species of Cordycein, dug up in his garden at 

 Double Bay.
