NOTES AND EXHIBITS. 



Mr. W. W. Froggatt exhibited a twig from a fruit-tree obtained 

 near Sydney which had 150 eggs of an undetermined grasshopper 

 attached to it in a double row; also a number of the newly 

 hatched young insects. These were of interest because of their 

 remarkable resemblance to a common Q,nt{Iridomyrmex purpureiiSy 

 Sm.), which is plentiful in the orchards and bush about Sydney, 

 hunting over the trees for food. It seems probable that this may 

 be a case of protective mimicry, the grasshoppers perhaps being 

 protected against the attacks of insectivorous birds, and the ants 

 also deceived. Brunner has described a remarkable little Plianero])- 

 ferid from the Soudan under the name of Myrmecophana fallax 

 which is very like the insect exhibited. In Brunner's species 

 the under part of the base of the abdomen is white, so that the 

 grasshopper looks as if it had a stalked abdomen when viewed 

 from the side. As the insect was wingless and without an 

 ovipositor, it may have been immature like those exhibited. 



Mr. J. Mitchell, of Newcastle, forwarded a brief note announcing 

 his discovery of the print of an insect's wing in the shale over- 

 lying the Yard Seam of coal at the base of Flagstaff Hill, New- 

 castle. There was, he believed, no previous record of the presence 

 of insect remains in rocks of the Permo-Carboniferous Age in 

 New South Wales. He hoped to be able to exhibit the specimen 

 at a future meeting. 



Mr. Maiden showed herbarium specimens of the Eucalypt 

 described in his paper. 



Mr. Baker exhibited herbarium specimens of, and essential oils 

 and extracts from the two Eucalypts described in his paper. 

 Also, in illustration of Mr. Harper's paper, photographs and 

 drawings of the aboriginal stones treated of therein. 



Mr. Palmer exhibited a living Gecko, Gymnodactylits platyurus, 

 White, and a large snake, Diemenia superciliosa, Fischer, from 

 the Blue Mountains. Also, from the Mountains, plants of two
