at Pcracleniya, Ceylon, a position he had held since 1849 till his retirement a few 

 years since, and his name will long be remembered in connection with the spread of 

 Cinchona culture, &c., in the island. Before his departure for the east he had made a 

 reputation as a cryptogamic botanist, but he also turned his attention to Entomology 

 and published several short notes in the Proceedings of the Entomological Society, 

 &c. During his long residence in Ceylon he constantly forwarded consignments of 

 insects to his friend Professor Westwood, who has described many curious forms 

 (especially in Paussidm) from his collections. Only last year Professor Westwood 

 described a singular laryal form, sent by him, the ordinal position of which remains 

 doubtful (c/. Trans. Ent. Soc, 1881, pp. 601—603, pi. xxii). He was a man of 

 simple habits, and for many years a strict vegetarian. He was elected into the 

 Entomological Society so long back as 1838, into the Linnean Society in 1854, and 

 into the Koyal Society in 1865.

Mr. J. Jenner Weir stated that he had recently observed an eel rise and take 

 a caterpillar from oS the edge of a leaf of Niiphar lutea ; and he referred to a 

 recent article in Chambers's Journal with regard to the proceedings of a pet trout, 

 and its discrimination of caterpillars in respect to colour, &c. 



Mr. McLachlan exhibited about 500 specimens of Nenroptera of various families, 

 being part of a collection he had made in July, chiefly in Switzerland and in the 

 Val Anzasca, North Italy. Amongst others were twelve species of RliyacopJdla, in- 

 cluding about forty examples of a new species from the Val Anzasca (and Val 

 Cannobina), and several oi Rh.Meyeri, McLach. (from the same localities), hitherto 

 known from a single specimen. There were also many specimens of ConiopterygidcE, 

 including a species in which the wings (at any rate, in one sex) were marked with 

 grey blotches (fi'om the Val d'Anniviers), and another with nearly black wings (from 

 Val Levantina), both divergent from the ordinary unicolorous white condition. He 

 also exhibited a large piece of the so-called " indusial limestone " of Auvergne, re- 

 cently given to him by Mr. H. W. Jackson, M.K.C.S., F.G-.S., who had obtained it 

 from near Eomagnat in Auvergne. In calling attention to the fact that this singular 

 geological formation appeared to consist entirely of masses of shell-covered caddis- 

 cases, he read an extract from Lyell's " Manual of Elementary Geology," in which 

 a probable explanation of the circumstances tending to produce the formation is 

 given. He also stated, that although these cases must have pertained to the Limno- 

 philidce, fossil remains of insects of that family of Trichoptera were almost unknown, 

 whereas others, of other families, apparently less suited for preservation in a fossil 

 state, were plentiful. 



The Rev. H. S. Gorhara asked why it was that recent cases of this kind were 

 so frequently formed wholly of one kind of shell ? 



Mr. McLachlan said it was apparently owing to the conditions under which 

 particular larv£e found themselves with regard to building materials. 



Miss E. A. Ormerod exhibited a species of Lina, which was stated to be doing 

 great damage to hazels and willows in Norway. She also made some remarks on 

 " rape-seed cake," and its effects upon wire-worms. The Indian cake was manu-
