Exhibitions, &c.
Mr. F. Bond (on behalf of Mr. Cooke, of Brighton) exhibited another specimen of the North-American butterfly, Danais Archippus, taken during the second week of September last by Mr. Alford Wood, of New Close, Keymer, Sussex, flying over a field of clover near Hassock's Gate. This was the third specimen recorded as having been taken in this country; the first having been captured near Neath on the 6th September, and the second near Hayward's Heath on the 17th October, 1876, and recorded in the 'Entomologist's Monthly Magazine' for October, and in 'The Entomologist' for December, 1876.
The President brought for exhibition a specimen of the singular butterfly Bhutanitis Lidderdalii, Atkinson, from Bhotan. He also read a letter which he had received from Baron v. Osten-Sacken, referring to his paper on the genus Systropus, published in the last part of the 'Transactions' of this Society, in which he had stated that a species received from Natal (S. crudelis) had been bred from a cocoon resembling that of Limacodes, found on a tree of the genus Mimosa. The letter referred the President to a paper by Benj. D. Walsh in the 'Proceedings of the Boston Society of Natural History' (vol. ix., p. 300, 1864), in which he relates that he had bred a dipteron from a cocoon of Limacodes hyalinus. This dipteron, which he had communicated to Baron Osten-Sacken, proved to be the common North-American Systropus (S. macer, Loew), and was a remarkable instance of community of habit among insects of the same genus in far distant regions.
The President had also been informed by M. Ernest Olivier, of Moulin, who had recently visited Pompeii, that he had observed large numbers of Bombylii flying in company with a bee of which he had forwarded a specimen, but this proved to be an Anthophora (probably A. nigrocincta), and
