Mr. Froggatt exhibited a fine series of specimens of male and 

 female Mountain-grasshoppers, Acridopeza reticulata {Locustidce). 

 They were received from Mr. Arthur McConochie, Gnomery 

 Station, Brewarrina, who reported that they were feeding on 

 Sowthistle. He showed, also, branchlets of Peppermint-gums 

 from Salisbury Park, near Uralla, girdled by the larvae of some 

 undetermined longicorn beetle, which remains in the fallen 

 branches. There are thousands of acres of the open forest- 

 country, where the surface of the ground is littered with dead 

 branchlets. 



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

 National Herbarium comprising : Zinnia elegans Jacq., Sydney 

 Botanic Gardens (J. H. Camfield; April^ 1906), showing floral, 

 and foliar prolification of the inflorescence. The ray florets are 

 elevated on adventitious stems which arise from the still adherent 

 floral bracts, the lamina of the ligula at this stage exhibits vires- 

 cence, and is seen to enclose an abortive, miniature flower-head. 

 In both ligulate and tubular Howers the achenes are early 

 attenuated and infertile. — Zinnia Hort. var.. Hunter's Hill (H. 

 Deane, 1902), showing lateral, foliar prolification of the inflores- 

 cence. Reduced branches with opposite leaves and miniature 

 foliaceous flowers arise from the axils of the involucral bracts of 

 the primary flower-head, its tubular florets are raised on lengthy 

 peduncles, and several ray-florets are represented by lateral leafy 

 ligulse, the remainder being suppressed. — Citrus medica Linn., 

 Beecroft (W. M. Carne; August, 1914), showing dialysis of the 

 carpels. The pericarp is seen to be laterally ruptured, and the dis- 

 jointed placentas have protruded, disclosing the seeds. — Carc?2^ws 

 lanceolatus Linn.(W.Muggridge; February, 1904), showing lateral, 

 foliar prolification of the inflorescence. A series of pedunculate 

 adventitious buds consisting of involucral bracts, and with no 

 trace of reproductive organs, occurs within the ordinary involucre 

 of the capitate inflorescence.— 6^ooc?e?ua dimorpha Maiden &
