between the bark and wood — both larvae and perfect insect 

 live on the woody fibre ; a Locustu viytiitissiiva, McCoy, the 

 largest locust of South Australia : a spectre insect from the 

 South-East, probably the male of Fodacantlnis wilkinsoui, 

 Macleay. Mr. Tepper also exhibited an Aj^hodius hoivitti, 

 Hope, a beetle that made its appearance in great numbers 

 in February last at Mount Gambler. This insect is well 

 known in Eastern Atistralia, but has not before been re- 

 ported from South Australia. The larvae and insect live in 

 and feed on manure, as does A . granarius and A . lividus. 

 These beetles are not injurious. Mr. Tepper exhibited a large 

 fungus from a Ei(,cal//2rtus and the insects (Necrohia ntfipes) 

 which destroy it. The President (Dr. Verco) exhibited 

 specimens of travertine, deeply grooved, from St. Francis 

 Island, Nuyt Archipelago. The grooves or scratchings are 

 said by the islanders to be produced by penguins, numbers 

 of which birds are found there, running up the face of the 

 rock. Mr. Hoavchtn stated that these grooves, which he 

 pointed out had a radial tendency, are very commonly found 

 in limestone rocks, and are caused by the slightly acidiilated 

 rainwater running down their sloping faces. A specimen 

 thus scored was shown by Mr. Hoavchin that had been 

 brought from Flinders E.anges. A piece of shelly limestone 

 from Denial Bay, sent to Mr. Hoavchin by Dr. Abbott, was 

 shown. This, Mr. Hoavchin considered, had been consoli- 

 dated above sea-level, but was now, he stated, dredged up 

 from the sea-bottom. This would seem to indicate oscilla- 

 tions in the land-levels.

 onded by Mr. Rutt "that His Excellency Sir Day Hort 

 BoSANQUET be requested to become Patron of the Society."
