Mitchell described a graphic formula, designed for the purpose of repre- 

 senting Geographical Distribution. The regions were indicated by lines, the 

 subregions by symmetrically placed numbers. This formula could be drawn 

 rapidly and printed without engraving. — Mr. W. L. Sclater read the 

 description of a Jerboa from Central Asia, which he proposed to refer to a 

 new genus and species of Dipodinae under the name Eucoi-eutes naso. — P. 

 L. Sclater, Secretary.

24th September, 1890. — 1) Stray Notes on Lepidoptera. No. I. By 

 A. Sidney Olliff , F.E.S. — 2) Revision of the Genera Colpochila (includ- 

 ing Haplonycha) , Sericesthis, and their Allies, with descriptions of new 

 Species. Part I. By Rev. T. Blackburn, B.A., Corr. Mem. This paper 

 commences the revision of the second division of the group Heteronycides 

 (Fam. Melolonthidae] of M. Lacordaire characterised by the possession of 

 normal elytra and simple claws. Between twenty and thirty species of Colpo- 

 chila and Sericesthis are proposed as new. — 3) Notes on Australian Coleo- 

 ptera with descriptions of new species. Part VIII. By Rev. T. Blackburn, 

 B.A., Corr. Mem. A new genus and about thirty new species referable to 

 various families are described. — 4) Description of a new Genus of Cysti- 

 gnathoid Frogs from New South Wales. By G. A. B oui eng er. (Communi- 

 cated by J. J. Fletcher.) The new genus, Phanerotis^ comes nearest to Cryp- 

 iotisj Gthr., but in respect of the arrangement of the vomerine teeth approaches 

 Limiiodynastes. Habitat, Richmond River district. — 5) Diptera of Australia. 

 Nematocera. — Supplement II. By Frederick A. A. Skuse. The present 

 contribution includes descriptions of additional species belonging to the 

 families Mycetophilidae, Simulidae, and Bibionidae. Mycetophilidae : — 

 {Lygistorrhina, gen. nov., 1; Heteropterna, Sk., 1; Phiyura, Meig., 3; Scio- 

 phila, Meig., 5; Neoempheria, O.-Sack., 1; Sienophragma, gen. nov. (syn. 

 Homaspis, Sk., praeoc), 3; Acrodicrania, Sk., 1; Clastobasis, gen. nov., 1; 

 Sceptotiia, Winn., 1; Mycetophila, Meig., 1; Delopsis, gen. nov., 1; Dynato- 

 soma, Winn., 1; Brachydicrania, Sk., 1; and Synplasta, gen. nov., 1). Simu- 

 lidae: — [Simulium, Latr., 1). Bibionidae: — [Piscia, Wied., 1; Dilophus, 

 Meig., 3; and Scatopse, Geoff., 1). The genus Lygistorrhina is proposed for 

 a remarkable species possessing a very long proboscis, a peculiar alar-vena- 

 tion, and exhibiting certain characteristics of Sciara. Neoempheria, Sceptonia, 

 and Dynatosoma are recorded for the first time from Australia. Among the 

 Bibionidae, Piccia melanaspis, Wied., Piscia fulvicollis, Fab., both originally 

 described from Java, and Scatopse notata, Linn., a well-known European 

 species, are found to occur also in Australia. Altogether, five genera and 

 twenty-six species are described as new. — 6) Studies in Australian Ento- 

 mology. No. IV. By T. G. Sloane. Seven new species, necessitating three 

 new genera (Fam. Carabidae), are described. — Mr. Froggatt read a ,,Note 

 on the Life-History of Pterygophorus cinctus, Klug", which will appear in 

 full in the Proceedings. Larvae of P. cinctus were found in April and May 

 feeding on Leptospermum ; unlike the larvae of Perga, they neitlier herd in 

 social clusters during the daytime nor do they fabricate cocoons. On the 

 contrary, they feed during the daytime, evidently sufficiently protected by 

 their colour and their resemblance to twigs, the specimens experimented with
