specimens exhibited by him at the meeting of the Society in September last, and then 

 new to Britain. 



Mr. M'Lachlan also exhibited an example of Oohsenheimeira vacculclla found at 

 Lewisham, on the 28th ult., in a most singular situation for the imago of a Lepi- 

 dopterous insect, namely, under close bark on the slump of an old alder tree, about 

 three feet from the ground. 



Mr. Bund exhibited tlie larva of Drilus flavescens, found near Folkestone. 



Mr. Lewis exhibited a living example of Chlajnius Schrankii, of which he had 

 lately taken about sixty specimens near Liiccombe, Isle of Wight. 



Dr. Wallace exhibited a specimen of Deilephila lineata, taken by Dr. Burkill, in 

 1856, at Tremeri, in Ireland ; and Agrolis valligera, from the same locality. He also 

 exhibited examples of the following species, which he had lately found on a recent 

 visit to Waterford, namely, Leucania littoralis, Mamestra abjecta, Cidaria populata, 

 Larentia salicaria, Eupilhecia deuotaria, E. conslrictaria, E. salyraria, Acidalia im- 

 mutaria, and A. inoniaria. Euchelia Jacobseae and Cetonia aurata were in great 

 plenty in the neighbourhood ; the latter species, he was informed, had been very rare 

 till late years. 



Mr. Mitford exhibited fine specimens of Trochilium Chrysidiformis, Timandra 

 prataria, and Spilodes palealis, taken near Folkestone. 



Mr. Westwood exhibited a mass of the empty cocoons of Ilythia sociella, for- 

 warded to him by Professor Harvey, of Dublin, of which the Irish naturalists had 

 failed in determining the nature, which had been taken from the stomach of a cow. 

 The only explanation which he could give of so unusual a situation was, that, as the 

 social caterpillars of these species frequent the nests of humble bees in considerable 

 numbers, it was probable that the cow, whilst grazing, had come upon the nest of a 

 moss-carder Bombus, and had chewed it together with the grass, the stomach not 

 having had the power to dissolve the mass of cocoons. Mr. Bond confirmed this 

 opinion, having found the mass of cocoons of the Ilythia in the nest of the moss- 

 carder bee. 



Mr. Westwood had observed, last season, some elm trees near Oxford, which were 

 infested by the Scolytus destructor in the heat of the summer, exuded sap, and 

 attracted large quantities of insects. One of these, this season, has died oif, still 

 emitting small jiatches of exlravasated sap : this had attracted vast quantities of 

 Cetonia aurata, the tree from the base of the trunk to the topmost branch being 

 covered by hundreds of specimens, in clusters of a dozen or score together, producing 

 shining masses visible at some distance, and which had attracted Mr. Westwoud's 

 attention to the insects. Many had become so slupified from the fluid they had 

 imbibed that they had fallen down helplessly to the ground. Their sense of smell 

 must have been extremely acute, and the odour of the sap (in very small quantities in 

 each place) very penetrative and diffusive, in order to have attracted so great an 

 assemblage of beetles. 



Mr. Douglas remarked that an almost imperceptible exudation from the trunks of 

 trees was often caused by the young larva of Cossus ligniperda. 



Mr. Tegetmeier described a practical application of Sbirach's discovery re- 

 specting the power of bees to raise a new queen from a neuter or worker grub ; 

 by means of which the contents of old hives can be taken without destroying 

 the bees or sacrificing any brood. The plan consists in driving out the queen,
