meso-thorax. He also showed larvte and ^upse of insects in 

 air-tight glass tubes in which a little cotton wool, sprinkled 

 with formalin, had been placed. The specimens, which had 

 been thus preserved for nearly two years, had lost little of 

 their original colour or brilliancy. 



Mr. Gahan exhibited pupa-cases of a Longicorn beetle, 

 Plocederiis ohesus, Gah., which were remarkable in being 

 composed almost wholly of carbonate of lime. It was not 

 known how the pupa-cases were fabricated, but presumably 

 the larvaj must possess special lime-secreting glands. 



Papers, etc. 

 Mr. R. McLachlan, F.E.S., read a paper on "A second 

 Asiatic species of Corydalis,^' and exhibited the male type of 

 the species described, which he proposed to name Corydalis 

 orientalis. He said the fii'st Asiatic species of Corydalis was 

 described and figured by Prof. Wood-Mason in 1884, the genus 

 up to that time having been considered to be peculiarly 

 American. Mr. H. J. Elwes, F.R.S., communicated a paper 

 " On the Lepidoptera of the Altai Mountains " ; and the Rev. 

 A. E. Eaton a paper entitled " An Annotated List of the 

 Epheineridee. of New Zealand." 



October 4th, 1899. 



Mr. G. H. Verrall, President, in the Chair. 



The President announced the death, at the advanced age of 

 eighty-six years, of M. Hippolyte Lucas, an Honorary Fellow 

 of the Society. He gave a brief account of the career, and 

 eulogised the work, of the distinguished French Entomologist. 



He also announced the death of Mr. Samuel Stevens, and in 

 reference thereto said the Society had to deplore the loss of 

 one of its oldest and most highly esteemed Fellows. Mr. Stevens 

 was formerly for many years Treasurer, and had also been a 

 Vice-President, and during the whole period of his long con- 

 nexion with the Society had always shown the greatest interest 

 in its welfare. That this interest had up to the last continued 

 unabated was manifested by the terms of his will, in which he 

 had made a bequest to the Society.
