VOL. III. TWENTY-FIFTH ANNUAL GENERAL MEETING, ANDERSON'S UNIVERSITY BUILDINGS, SEPTEMBER 26TH, 1876. Mr James Ramsay, Vice-President, in the chair. The Treasurer submitted his annual Financial Statement for the past year, which showed a balance in favour of the Society of £39 1s. 4d. It was explained that the smallness of this balance as compared with that with which the session commenced, arose from the cost of printing, two parts of the Proceedings having been charged in the accounts of the year. The Secretary read the Report of the Council on the business of last session. During its course sixteen members had been admitted. Five had died during the same period, several of whom had been active and useful associates. Notwithstanding the losses by death, removals, etc., some progress had been made during the year, the roll standing at present at 135 as against 131 reported last year. Eight meetings had been held during the session, and these had been generally well attended. The business was of the usual varied character. The exhibition of specimens embraced all departments of natural science; and the papers read were of an interesting character. These are in course of publication, and will shortly be in the hands of members. A number of excursions to places of interest in the neighbourhood had been arranged for the summer months, but from various causes, were not so largely taken advantage of as had been expected. The Council hopes that an effort will be made to carry out during the session now commencing, what is one of the primary objects of the Society, and one so well calculated to promote its interest and usefulness. The Librarian reported that the books were all in excellent order, and the use of them largely taken advantage of by the members. The exchange of publications with kindred Societies had been considerably increased, and was still capable of larger extension. The following gentlemen were elected office-bearers for the session:-Professor John Young, M.D., F.G.S., F.R.S.E., President; James Ramsay, Thomas Chapman, and James Barclay Murdoch, Vice-Presidents; Robert Mason, Secretary; R. J. Bennett, Treasurer; Peter Cameron, Librarian; Hugh M'Bean, John Kirsop, James Coutts, James Lumsden, F.Z.S., Duncan M'Lellan, Henry C. Young, David Corse Glen, C.E., F.G.S., John Young, F.G.S., and Francis G. Binnie, Members of Council. Messrs John Robertson, James Paton, Joseph Somerville, and James T. M'Callum, were elected ordinary members of the Society. SPECIMENS EXHIBITED. Mr Thomas Chapman exhibited specimens of Papilio antimachus from Western Africa, the largest butterfly, and one of the rarest species, known; also, from Cape Coast Castle, specimens of the large beetle Goliathus drurii, on which he made a few remarks. PAPERS READ. I.—On a peculiarity in the habits of a species of Cirropsilus. By Mr PETER CAMERON. Mr Cameron said-The Chalcididae exhibit in their manner of pupation two forms. In the one case the pupa has each limb enveloped in a separate thin, transparent white pellicle, which does not enfold the organ in a very compact fashion, and when these skins are cast off they do not retain the shape of the creature whose body they covered. In the other type the skin of the pupa is hard and thick, and remains of the same shape after the insect has left it, as it did before. It, moreover, closely envelopes the limbs of the pupa, so as to give it the appearance of the obtected pupa of the lepidoptera, and in no other hymenopterous family do we find pupae of this nature. It seems to be the case also that these two forms are correlated with differences in the habits of the insects, for those of the first class are parasites on gall flies, or on wood boring insects, and they pass the pupa state enclosed in the galls, etc., in which they lived; while the other tribe are attached to free feeding larvae, and they pass the period of quiescence in a position more or less exposed.
