NOTES AND EXHIBITS. 



Mr. D. G. Stead exhibited a beautiful Sand-Eel from Cowan 

 Bay, Hawkesbury River; several specimens of two species of 

 Locustidce, and two Geckos from Tanna, New Hebrides; specimens 

 of Ceratothoa, a crustacean parasitic chiefly in the mouths of the 

 Yellow ta,i\(Trachur2is); and the larvte of a common moth, Agarista 

 glycine, Lewin, which at present are doing great damage to the 

 young grapes in the vicinity of Sydney. 



Mr. Steel exhibited a ver}^ fine collection of beautifully pre- 

 served specimens of different species oi reripatusivom. the various 

 Australasian Colonies, South Africa and Chili. 



Mr. Froggatt exhibited specimens of a ladybird beetle, Crypto- 

 laemus MotUrouzieri, Muls., the larvse of which ha\e been very 

 numerous for the last month on the Norfolk Island and Bunya 

 Pines all round Sydney, feeding upon a scale, Dactylopius auri- 

 lunatus, Mask., which if it were not thus kept in check would 

 cause considerable damage to the trees. As the larvae after feed- 

 ing upon the scale cover themselves with the remains of the scale 

 insects, they give the bark of the trees the appearance of being 

 covered with lime-spots. This leads to their being destroyed under 

 the impression that they are scale insects. 



Mr. Froggatt also showed cultures of a fungus, Sporotrichium 

 globuliferum, Spey, which has been largely used in America to 

 destroy the Chinch Bug {Blissis leucoj^terus). As this pest is 

 closely allied to the Australian Rutherglen l^ng^Nysius viiiitor), 

 it is proposed to experiment upon the latter with the fungus. 



Mr. W. S. Dun exhibited, from the Geological Survey Museum, 

 a specimen of shale from the Sydney Harbour Colliery shaft at 

 Balmain obtained at a depth of 2870 feet. The specimen shows
