ORDINARY M ^NTHLY MEETING. X^''^ A?A»^ ^5^ 

 August 25th, 1915. 

 Mr. A. G. Hamilton, President, in the Chair. 



The Donations and Exchanges received since the previous 

 Monthly Meeting (28th July, 1915), amounting to 7 Vols., 40 

 Parts or Nos., 10 Bulletins, and 2 Pveports, received from 41 

 Societies, etc., were laid upon the table. 



NOTES AND EXHIBITS. 



Mr. Froggatt exhibited specimens of a small longicorn beetle, 

 Bethelium mundum Blackb. At the Meeting of the Society in 

 September, 1914, a number of branchlets of the Peppermint- 

 Gums {Eucalyptus sp.), from near Uralla, N.S.W., cut off the 

 trees by the larvae of some unknown beetle, were shown. 

 This year, at exactly the same time, the branches again began to 

 strew the ground, all over the district. On examining infested 

 twigs that had been kept in a breeding-cage throughout the 

 interval, a number of the small longicorn-beetles exhibited, were 

 found to be emerging from the dry twigs. The life-cycle is thus 

 just about a year. The larva, falling to the ground with the 

 severed branch, first gnaws its way into the nearest dead knot, 

 and then feeds just under the surface of the bark; when full-fed, 

 it bores into the hard wood and pupates. 



Mr. A. A. Hamilton showed a series of specimens from the 

 National Herbarium — Pw?^e?ifm scahra R.Br., (Mt. Wilson; Dr. 

 J. B. Cleland; June, 1915), exhibiting fasciation and torsion. 

 The stem, at first terete, exhibits dilation, followed by banding; 

 and, eventually, its frequent concomitant torsion. Branches 

 springing at various points from the verges of the stem, within 

 the banded region, have more or less attenuated flowers in the 

 axils of their upper leaves, together with a diminutive terminal 

 cluster, denoting adherence to the normal floral arrangement,
