Abstract of Proceedings, September 30th, 1908. — 1) On some remark- 

 able Australian Libellulinae. Partii. Descriptions of new Species. By 

 P. J. Tillyard, M.A., F.E.S. — The general tendency of the remarkable 

 Libellulinae found in tropical Australia appears to be one of gradual 

 simplification along the following lines: — 1) Abolition of superfluous ner- 

 vures; 2) loss of pruinescence; 3) decrease in size; 4) simplification of colour- 

 pattern; and 5) contraction and intensification of dark pigmentation of the 

 wings. Eight species are added to the Australian list, of which six are pro- 

 posed as new. Camacinia othello, n. sp. , taken at Cooktown, is one of the 

 largest and most beautiful Libellulinae known, and exhibits well, in its 

 relation to G. giganlea, a common island species, many of the tende acies 

 mentioned above. — 5) Revision of the Australian Curculionidae belong- 

 ing to the Subfamily Cryptorhynchides. Part IX. By A. M. Lea, F.E.S. — 

 The ninth instalment of the Revision deals with the genus Chaetectetorus and 

 some of its allies, of which eleven genera, including four proposed as new, 

 and twenty species, including eight proposed as new, are described. The 

 group is abundantly represented in Australia and the Malay Archipelago, 

 though representatives occur in most parts of the world. — Notes and 

 Exhibits. The Secretary communicatet a letter from Dr. J. P. Cleland, 

 President of the west Australian Natural History Society, Perth, in which 

 the writer showed that the needs of West Australia in respect of proper reser- 

 vations for national parks, and satisfactory administration of the Game Acts 

 for. the preservation of marsupials and birds, were perhaps rather more urgent 

 than those of any other State. Dr. Cleland also forwarded a copy of a reso- 

 lution passed at the last meeting of the Society, expressing approval of the 

 efforts now being made to arous.e attention in the matter of the protection of 

 the indigenous flora and fauna; and offering cordial support. Mr. Froggatt 

 exhibited an interesting series of biting and blood-sucking Diptera from the 

 Soudan, Africa, received from Mr. Harold H. King, and including examples 

 of the Tsetse-Fly (Glossina morsitans Westw.) so destructive to stock in 

 South Africa, and the allied species, Glossina palpalis Desv., which transmits 

 the organism causing "sleeping sickness 1 '; a biting house-fly (Stomoxys sp.) ; 

 the Camel Louse Fly Hippobosca camelina Leech; and six common biting 

 horse-flies (Tabanidae) found in the Soudan. Acting-Professor Woolnough 

 exhibited a collection of Graptolites from a northern extension of the locality 

 on the Shoalhaven recently noted by Mr. Came. The Ordovician rocks occur 

 in the form of a narrow band extending from near Tolwong Creek, northwards 

 past the great bend of the Shoalhaven, through thè Razorback and Ballanya 

 Trig. Station to a point about one mile south of the Great Southern Railway 

 Line between Tallong and Marulan. Silurian and Devonian rocks are deve- 

 loped in the neighbourhood. This is the nearest point to Sydney at which 

 fossiliferous Ordivician strata have been met with.
