yet it exhibits no definite tropical forms (excepting the cosmopolitan Patitala 

 flavescens). The 320 specimens examined comprise only ten species, of which 

 eigth are common and widely distributed over Australia, while two are new. 

 On of these, Lestes aridus^ is closely allied to L. leda und L. analis, both 

 common around Sydney. The other, Austrosticta fieldi, of which only three 

 more or less imperfect specimens are in the collection, is regarded as the 

 type of a new genus. Though insignificant in size and colouring, it is a most 

 interesting and remarkable insect. Its nearest ally is Isosticta simplex Martin, 

 found in Eastern Australia, from which it differs in several important details 

 of wing-neuration and in the form of the and appendages. — 3) Memoir on 

 a fewHeteropterousHemiptera from Eastern Australia. By G. W. Kirkaldy, 

 F.E.S. — This memoir records the Heteroptera collected by Mr. A. Koebele 

 and Dr. R. C. L. Perkins in Queensland, and by M. Koebele in New^ 

 South Wales. These expeditions were carried out under the auspices of the 

 Hawaiian Sugar Planters' Association at Honolulu, for the purpose of discov- 

 ering and forwarding predators and parasites for the control of certain insect 

 pests of sugar cane in the Hawaiian Islands, and the resulting collections are 

 preserved in the cabinets of the Division of Entomology. The Homoptera 

 have been already worked out (1906, Bull. Ent. Hawaiian Sugar Planters 

 Assoc. I. 269—479, PI. XXL— XXXIII. ; 1907, op. cit. III., 1, PI. I.— XX. 

 and figs.). The Heteroptera were not specially collected, and were merely a side 

 issue; nevertheless seven genera and twenty-five species are proposed as new. 

 Abstract of Proceedings, November 27th, 1907. — Mr. D. G. Stead 

 exhibited a curiously deformed right claw of a large Mangrove Crab, Scylla 

 serrata (Forskai), which showed a remarkable "attempt" at the formation of 

 a supplementary "nipper" on its lower surface. — Mr. Kesteven exhibited 

 preparations of the eyes of a tadpole, of a species oï Hyla^ from the Histolo- 

 gical Laboratory of Sydney University. The elements of the retina, more 

 especially the rods and cones, were more easily studied in such preparations 

 than in those of mammalian eyes in general.
