the prothorax passing backwards and forwards over a striated space at the 
base of the scutellum. 
Mr. C. O. Waterhouse exhibited, for Mr. Frohawk, a series of wings 
of British Butterflies, prepared in accordance with a process (described by 
Mr. Waterhouse in the Proc. Ent. Soc. 1887, p. xxiii), by which they were 
denuded of their scales so as to expose the neuration. 
Dr. P. B. Mason exhibited cocoons of a species of spider,—Theridion 
pallens, Black.,—from Cannock Chase, distinguished by the presence of 
large blunt processes on their surface. 
Mr. H. Goss exhibited, for Mr. N. F. Dobrée, a number of scales of 
Coccida, picked off trees of Acacia melanoxylon and Grevillea robusta, 
growing in the Market Square, Natal. These scales had been referred to 
Mr. J. W. Douglas, who expressed an opinion that they belonged to the 
Fam. Brachyscelida, and probably to the genus Brachyscelis, Schrader. He 
said that most of the species lived on Hucalyptus. 
Captain H. J. Elwes exhibited a long and varied series of Terias 
hecabe. He remarked that all the specimens which had strongly defined 
chocolate markings were taken in the cold and dry season, and that 
those which were without, or almost without, markings were taken in 
the hot and wet season. Capt. Elwes further observed that he believed 
that many specimens which had been described as distinct were merely 
seasonal forms of this variable species. Mr. W. L. Distant, Mr. F. D. 
Godman, Prof. Meldola, Mr. H. T. Stainton, and Mr. G. Lewis took part 
in the discussion which ensued. 
Mr. W. Dannatt exhibited specimens of Thaumantis Howqua, West, 
from Shanghai. 
Mr. H. Burns exhibited, and made remarks on, a number of nests of 
living ants of the following species, viz., Formica fusca, Lasius alienus, 
L. flavus, L. niger, Myrmica ruginodis, M. scabrinodis, &e. One of the 
nests contained a queen of L. flavus which had been in the exhibitor’s 
possession since September, 1882. 
Mr. G. C. Bignell communicated a paper entitled “ Description of a 
new species of British Ichneumonide.” 
Mr. A. G. Butler communicated a paper entitled “A few words in 
reply to Mr. Elwes’ statements respecting the incorporation of the Zeller 
Collection with the General Collection of Lepidoptera in the Natural 
History Museum.” Capt. Elwes, Mr. Stainton, Mr. Godman, and others 
took part in the discussion which ensued.—H. Goss and W. W. Fow.xr, 
Joint Hon. Sees.
