upon it as being the first recorded instance of the occurrence of the curious insects 

 of this Family in America. He also exhibited a photograph of a Dragon-fly wing 

 sent to him by Dr. Puton. This was the production of a young medical student at 

 Lyons, and was prepared simply by placing the wing under glass upon a piece of 

 sensitized paper and exposing it to light, the neuration showing out most beautifully 

 distinct in white on the dark ground. Mr. Meldola said any number of impressions 

 might be produced from this, photographed upon glass. It appeared admirably 

 adapted for truthfully detailing complex neuration. 



Mr. Billups exhibited a specimen of a species of Homalomyia bred by him, in 

 which the left intermediate leg was perfectly double, so far as regarded the tibiae 



and tarsi. 



Baron Osten-Sacken communicated " Facts concerning the importation, or non- 

 importation of Diptera into distant lands," in which much curious information was 

 given, mostly in connection with North American species. 



Mr. Rosenstock communicated a paper on Australian Lepidoptera. 



Colonel Swinhoe communicated notes on the larvae and habits of many species 

 of Indian Lepidoptera. 



November 5th, 1884 : The President in the Chair. 



A. W. Kappel, Esq., of Burlington Gardens, Chiswick, was elected a Member. 



Mr. Douglas sent for exhibition specimens of the new British Homopteron 

 Idiocerus cognatus, Fieb. {cf. ante pp. 127 and 162), taken by him at Lewisham, 

 with examples of /. tremulce, Estl., for comparison. Also the following Coccidce 

 from Lewisham, viz., Lecanium ribis, A. Fitch, from red currant (which, however, 

 did not appear to materially damage the plants) ; L. cesciiU, KolL, <? imago, and 

 S and ? " scales," from horse-chestnut ; L. aceris, auct., S and ? " scales," from 

 sycamore ; L. genevense, Targ. ?, S ^"d $ " scales," from hawthorn ; L. coryli, L., 

 ^ " scales," from hazel. Likewise parasitic Chalcididcs {Coccophagus and Encyrtus ?) 

 bred from the last four species. 



Mr. Felton (present as a visitor) exhibited a large collection, principally Cole- 

 optera, from Espirito Santo, Brazil. There appeared to be some interesting species, 



Mr. Meldola exhibited the example of Nonagria sparganii, Esp., from Deal, 

 recorded at ante p. 135. I 



Mr. Theodore Wood exhibited Cis hilamellatus, from West Wickham, re- , 

 cently described by him {cf. ante p. 130). ! 



Mr. W. F. Kirby exhibited specimens of Ephestice bred from cocoa in a ware- ' 

 house in London ; they were mostly E. elutella, but JE. parasitella was also appa- 

 rently present. They occasioned great damage. Mr. McLachlan suggested " baking " 

 as a remedy, but it was remarked (by Mr. Weir and others) that this remedy was 

 scarcely applicable in large warehouses, with innumerable bags of the material stored ; 

 therein. Mr. J. J.Walker said that JiJphesticB affected ship biscuits, and lime H 1 

 washing was found useful in such cases. Mr. McLachlan said that the insects would 

 feed indiscriminately on any comparatively dry material, and Mr. Stainton doubted i 

 if any warehouse in London were free from them. 



Mr. Olliff exhibited a specimen of the very rare Parandra 6-striata, from the !|f 

 Zambesi, belonging to the Museum at Amsterdam. 



Baron Osten-Sacken communicated a new and revised edition of his Essay on 

 Comparative Chsetotaxy in Diptera, in which the importance of the characteristic! 

 bristles as a means of classification was insisted upon, as were also the connection! 

 of the bristles with the condition of the eyes, and of the latter with the habits of| 

 *' poising " so well known in many Dipterous insects.
