(Newm.), from Mount Kosciusko, where it was common. Of 

 Pseuclo-Neuroptera there was a species of Ewbiidm from 

 Western Australia, and certain curious Psocida and Perlidee. 

 The Trichoptera appeared to be exclusively confined to Seri- 

 costomatidcB, Leptocerida, and Hydropsy chidce. Mr. Meyrick 

 made some remarks on the localities in which he had collected 

 the species. 



Mr. M. Jacoby exhibited three specimens of a new species 

 of Xenarthra, collected by Mr. G. Lewis in Ceylon ; also a 

 species of Loxoprosopus from Brazil. 



Mr. C. 0. Waterhouse exhibited a drawing of a flea which 

 he believed to be a new species. Numbers of specimens were 

 found on a small animal [Myrmecobius) from West Australia. 

 He proposed naming it Sarcopsylla myrmecobii. 



Mr. Waterhouse also exhibited a living example of an 

 Ichneumon — Ophion macrurum — bred from a larva of Callu- 

 samia prumethea, a North-American species of Saturnida. He 

 further exhibited a number of wings of Lepidoptera denuded 

 of the scales, in order to show the neuration for study, and 

 explained the method he had adopted for removing the scales. 

 The wings were first dipped in spirit and then placed in eau 

 de javelle (potassium hyperchlorite). Mr. Waterhouse said 

 he had sometimes substituted peroxide of hydrogen for eau de 

 javelle, but the action was much less rapid, although the 

 results were satisfactory. 



Mr. Poulton observed that, although the pigment bad 

 disappeared, he thought the scales were not removed, but 

 were merely rendered transparent ; and he remarked that 

 the discovery of some chemical for softening chitine had 

 long been wanted to prepare specimens for the microscope. 

 The discussion was continued by Mr. M'Lachlan and Dr. 

 Sharp. 



Mr. ISlater read a note, extracted from the 'Medical Press,' 

 on the subject of the poison used by certain tribes of African 

 Bushmen in the preparation of their arrows. It was stated 

 that a poison was prepared by them from the entrails of a 

 caterpillar which they called " N'gwa." 



The Rev. W. W. Fowler read the following extract from a 

 a letter received from Mr. J. Gardner, of West Hartlepool: —
