28th May, 1890. — 1) Botanical. — 2) On a new Australian Coccid. 

 By W.M. Maskell, F.R.M.S. (Communicated by A. Sidney OllifF, F.E.S.) 

 The very distinct Coccid described under the name Coelostoma australe is the 

 first of the genus recorded outside New Zealand. The type specimens were 

 obtained on a species of Angophora in the neighbourhood of Sydney, the 

 males being remarkable by the possession of a long brush-like tail. 3) Unde- 

 scribed Australian Lepidoptera from Brisbane, Queensland. By Thomas 

 P. Lucas, M.R.C. S.E., L.S.A. Lond., L.R.C.P. and L.M., Edin. Seven 

 species referable to the genera Nyctemera, Antheraea, lodis, Hypochroma, and 

 Xenosoma, are proposed as new. — 4) Notes on the Life-history of Australian 

 Saw-flies, with Description of a new Species, By W. W. Froggatt. Ob- 

 servations on the life-history of only two species of the characteristically 

 Australian genus Perga have hitherto been recorded, namely, P. Lewisi by 

 Prof. Westwood in 1836, and P. dorsalis by Mssrs. Bennett and Scott in 

 1859. In the present paper the observations of these authors for the two 

 species named are confirmed and supplemented, and ah account is given of 

 the metamorphoses of five other species, namely F. polita, Leach, an unde- 

 sribed species which is proposed as new under the name P. chalybea, P. 

 Foersteri, Westw., P. Latreillei^ Leach, and P. Spinolae, Westw. The larvae 

 of the seven species dealt with were obtained in the neighbourhood of Syd- 

 ney or Nundle, N.S.W., and the perfect insects were bred from them. A 

 description of P. chalybea is given, and some critical remarks are offered on 

 P. Spinolae, which turns out to be only the female of P. Latreillei, both having 

 been bred from the same batch of larvae. — 5) Notes on Australian Abori-

 — An abnormal form of Tomahawk from Port Stephens; No. IV. — A well 

 finished Tomahawk of ordinary form from Brisbane Water. ByR.Etheridge, 

 Jun., Palaeontologist to the Australian Museum and Geological Survey of 

 New South Wales. — Dr. Cox exhibited an albino specimen of Dacelo 

 gigas, obtained by Mr. Caley; also a very fine example of the base of the 

 stolon of a fossil plant [Calamités) from a road-cutting in the Hawkesbury 

 Sandstone at North Shore, He also made some remarks on a plague of mice 

 of at present undetermined species recently infesting his premises at North 

 Shore ; they first attracted attention in the garden by their depredations on 

 the flowers of Hibiscus ; then in the house, where they exhibited great par- 

 tiality for fruit, but avoided such articles as cheese ; ultimately becoming a 

 nuisance through their nesting in drawers and destroying papers for the pur- 

 pose of making their nests, — Mr, Palmer showed portions of the roots of 

 an apple tree infested with American Blight [Aphis lanigera). The plant was 

 supplied from a nursery as a blight-proof variety but had failed to maintain 

 its reputation. — Mr. Froggatt exhibited specimens of the "plague locust" 

 from Hay, Mulwala, N.S.W., and the Wimmera, Victoria; and he called 

 attention to the doubtful identification of this locust. In the Victorian Agri- 

 cultural Report for 1873, a description and figures of this insect and of the 

 "painted locust" [Oedipoda mtisica, Serv.) are given; but in the text the
