He exhibited specimens of Ips and Cryptarcha, mounted to show the organ 
Dr. Sharp also exhibited a box of Rhynchota, chiefly Pentatomide, in which 
the specimens were prepared so as to display the peculiarities of the terminal 
segment in the male sex. 
Mr, R. Adkin exhibited, on behalf of Mr. H. Murray, of Carnforth, 
a fine series of Polia wanthomista, var. nigrocincta, from the Isle of Man, 
and Cidaria reticulata and Emmelesia teniata from the Lake District. 
Mr. W. White exhibited a living larva of Zeuzera @sculi, and called 
attention to the chitinous scutum or thoracic segments with several rows of 
minute serrations, which evidently assist progression. He stated that the 
larva exudes from its mouth, when irritated, a colourless fluid, which he 
had tested with litmus-paper and found to be strongly alkaline. Prof. 
Westwood made some remarks on the subject. 
Captain H. J. Elwes exhibited a number of insects of various orders, 
part of the collection formed by the late Otto Méller, of Darjeeling. 
Mons. A. Wailly exhibited the cocoon of an unknown species of Antheraa 
from Assam ; also a number of cocoons and imagos of Anophe venata from 
Acugua, near the Gold Coast, West Africa; specimens of Lasiocampa otus, 
a South European species, which was said to have been utilized by the 
Romans in the manufacture of silk; also a quantity of nests containing the 
eggs of Hpeira madagascariensis, a silk-producing spider from Madagascar, 
locally known by the name of “ Halabe.” He also read extracts from letters 
received from the Rey. P. Camboué, of Tananarivo, Madagascar, on the 
subject of this silk-producing spider. 
Mr, H. Goss read a communication réceived by him from Prof. S. H. 
Scudder, of Cambridge, Mass., U.S.A.,on the subject of his recent discoveries 
of some thousands of fossil insects, chiefly Coleoptera, in Florissant, Western 
Colorado, and Wyoming. Prof. Westwood remarked on the extreme rarity 
of fossil Lepidoptera, and called attention to a recent paper by Mr. A. G. 
Butler, in the Proc. Zool. Soc., 1889, in which the author described a new 
genus of fossil moths belonging to the Geometrid family Huschemida, from 
& specimen obtained by Mr. A’Court Smith at Gurnet Bay, Isle of Wight. 
Mr. F. P. Pascoe read a paper entitled ‘ Additional Notes on the genus 
Hilipus,” and exhibited a number of new species belonging to that genus. 
The Rey. Dr. Walker read a paper entitled “ Notes on the Entomology of 
Iceland.” Mr. Roland Trimen asked if any butterflies had been found in the 
islands. Dr. Walker said that neither he nor Mr. P. B. Mason had seen any 
during their recent visit to Iceland, nor were any species given in Dr. 
Staudinger’s list. In reply to a question by Mr.G.C. Champion, Mr. Mason 
said that during his recent visit to Iceland he had collected nearly a hundred 
species of insects, including about twenty Coleoptera. He added that several 
of the species he had taken had not been recorded either by Dr. Staudinger 
or Dr, Walker. Capt. Elwes enquired if Mr, J. J. Walker, with his great
