the eggs were probably laid in the eg;g-bag of the spider, and the larvae would feed on 

 the youug spiders, or perhaps in iheir early stage on the egj;s. 



Mr. Albert Miiller exhibited a large number of galls on various plants, and called 

 particular atteniion to two kinds of excrescence on the leaf-stalk of the naaple {Acer 

 campeslre), described in the following note: — 



" Firstly. A Dipterous gall formed by a slender, club-like, reddish swelling of the 

 petiole, soLiieiimes in ils middle, sometimes at its junction wiih the leaf; cell one, 

 occupying the whole length of the ^all, and tenanted by the white larva of a Dipternn 

 as yet unknown to me, but which I am certain is not a Cecidomyia. In September, 

 1868, and again in the same month this year, I met with this gall on the identical 

 maple-bush in a hedge-row near Shirley, but until now all my attempts at rearing the 

 fly have utterly failed. 



" Secondly. Also on the petiole of the maple-leaf, a series of spur-like, solid red 

 excrescences, standing in a row, each about half a line high. These 1 am inclined 

 to attribute to the same Acarus aceris of Kaltenbach which causes the well-known 

 pear-shaped red galls on the leaves of this tree. But whether this be so or not, it is at 

 any rate w'orth while to point out, that insect agency can produce, on thornlcss plants, 

 excrescences closely resembling, or perhaps identical with, the natural thorns so 

 commonly met with in other groups of the vegetable kingdom." 



Mr. Miiller mentioned that the collection of galls formed by the late Mr. Wilson 

 Armisiead had been placed in the Museum of the Leeds Philosophical Society. 



Mr. Cutter (who was present as a Visitor) exhibited, on behalf of Mr. Christopher 

 Ward, several Diurnal Lepidoptera, including the female of Orniihopteva Brookeana, 

 various species of Charaxes, Papilio Zalmoxis, and a specimen of Papilio Autimachus, 

 captured one hundred and fifty or two hundred miles inland from Old Calabar. Of 

 this gigantic and remarkable butterfly the only example hitherto known was collected 

 by Smeaibman for Drury a century ago, was figured hy Drury and by Donovan, and 

 was finally taken with Drury's collection to Australia by William Sharp Macleay. 



Mr. Butler corrected an error in his paper (Tr. Ent. Sue. 1869, p. 273), where it is 

 stated that Aruynnis Aglaia and Niobe show every sign of being one and the same 

 species; for Aglaia read Adippe. And as to the occurrence of the form Niobe in 

 Britain, see Newman's ' Entomologist,' iv. 351. 



Mr. Wormald exhibited a small box of butterflies sent from Shanghai by 

 Mr. W. B. Pryer. Amongst them were Argynnis Midas, and a beautiful species of 

 Anthochaiis with falcate wings, apparently identical with the Japanese A. Scolymus. 



Mr. Dunning exhibited half a dozen moths bred and sent by Mr. E. Holdsworth, 

 of Shanghai. One was Heterusia remota (Walker, Cat. Lep. Het. B. M. p. 431), the 

 larvjE of which were found by Mr. Holdsworth in great numbers at Van Vun, about 

 six miles west of Soochow : the cocoon was described as " of very white colour, and of 

 a very paper-like nature." The other specimens were the subject of the following 

 extract : — 



" The specimens of a Borabyx have been reared by myself, from larvae found 

 feeding upon pine and dwarf oak at the hills near Van Vun. The larva when found 

 were full grown, and huirdreds of them had already spun their cocoons amongst the 

 needles of the pine trees, and so plentiful were they that every tree had three or four 

 cocoons on it. The following is a description of the larva as it appeared shortly before 

 spinning its cocoon. .Borfy.— Ground colour black or dark brown, covered with very
