328 NOTES AND EXHIBITS. 



SaiidNvich Islands, Fiji, and New Ireland, where it is found 

 boring in the stems of the plants much in the same way as the 

 sugir-cane moth borer ( Nonagria exitiosa, Oil.). The Sj^heno- 

 ])]iorus has not been recorded from Australia previously, and it is 

 significant that the specimens now exhilnted wei-e found in cane 

 in cultivation in Queensland, but only recently imported from 

 New Guinea. 



He also showed specimens of a remarkable parasitic fly (Fam. 

 Tachinidw) bred from adult becstles of the two-sj)Otted Monolepta 

 ( Monolepla rosea, Blk,), a destructive plant-eating species. 



Messrs. Maiden and Baker showed the plants referred to in 

 their paper. 



Mr. Maiden exhibited sections and photographs (of both external 

 and internal structure) of fresh specimens of Native Bread ( My- 

 lifta australis), showing the irregularly netted appearance of the 

 funi^us, which cannot be called hexagonal. He also announced 

 the almost complete absence of pectin in this fungus, and stated, 

 as the result of experiments not quite complete, that the tissue 

 appears to mainly consist of a modification of cellulose, most 

 probably fungin. 



Mr. Maiden also showed (on behalf of Mr. A. J. Sach, of the 

 Technological Museum, Goulburn) a supposed aboriginal imple- 

 ment of stone, shaped like^ a daggc^r, whose use appears to be 

 somewhat obscure, although it is deemed to have been used f(;r 

 beating fibres or seeds for food. 



Mr. Brazier exhibited a block of wood of undetermined specit s, 

 probably a Protead, from New Caledonia. 



Mr. Lea exhibited the Coleoptera — new si)ecies of Apaie, 

 Xylo])ertha, and of a new genus— descril^ed in his paper, chiefly 

 from Tani worth, N.S.W. 



]\lr. Helms exhibited a glacier-))olished slab of slate from an old 

 moraine at the base of Mt. Twynam, Snowy Mts., Australian A1})S.
