Tlio Chairmau read an address on the progress of entomological science in 
1867, and the proceedings closed with votes of thanks to the officers and retiring 
Members of Council ; with an especial acknowledgment of indebtedness to Mr. 
Dunning for his munificent gift of 100 guineas towards liquidating the heavy 
esijcnses incurred in publications during the past year. 
Fcbrum-y 3rcZ, 1868. H. W. Bates, Esq., F.Z.S., President, in the Chair. 
Mr. Bond exhibited a female example of Drilus flavescens (Suail-beetlc) which 
had been found by Mr. Harting, on the 1st April last, at Harting, Sussex, amongst 
a number of shells of Helix ericetorum. Also a singular specimen of Bomhyx 
quercus, exhibiting the colour of both sexes in longitudinal bands on the wings. 
Also a number of cast skins of Dermestes larvse, which latter had caused great 
damage by devouring the bladder used to cover jam-pots : with reference to those 
larvos, Messrs. Janson, Smith, and McLachlan mentioned instances in which they 
had bored into and fed upon wood ; the latter gentleman remarking that he had 
found them far in the interior of ship-timber. 
Dr. Wallace exliibited two examples of Bombyx Yama-mai bred in England last 
season ; also B. Pernyi from Cliina, another oak-feeding and silk-producing species ; 
and Pachypusa effiisa, an Acacia-feeder from South Africa, which pi'omised to be of 
little value to scriciculture. 
Mr. Smith exhibited a number of examples of the " Bugong" moth of New 
South "Wales (Agrotis spma), and read a letter fi-om Dr. Bennett, of Sydney, in 
which that gentleman stated that last year they had appeared in immense swanng, 
filling the houses and churches to such an extent as to interfere with Divine service. 
Dr. Bennett said they appeared to be all of one sex, but the specimens sent were 
about equally male and female. He also exhibited examples of the Australian form 
of Pyrameis cardid, capfcm-ed off Cape Otway, where it had appeared in great 
quantities. 
Mr. Trimeu exhibited a specimen of the very rare Apatura Tonia from Asia 
Minor, and made some remarks on its affinities. 
The Hon. T. De Grey exhibited a number of examples of HypercalUa Christier- 
nana which he had captured last season in Kent, between Shoreham and Sevenoaks ; 
likewise specimens of Acidalia rubricata and Opostega reliquclla from Suffolk. 
Mr. Dunning exhibited an example of the rare spider, Pliolcus phalangioides, 
taken by Lord Cawdor at Stackpool Court ; and read a letter from Mr. Blackwall, 
stating that he possessed a gynaudromorphous example of an Indian species, 
P. Lyoni. 
Mr. Smith exhibited a beautiful new species belonging to the genus Oryssus, 
from the Gold Coast. 
Mr. Hewitsou communicated a letter from Dr. Felder respecting the date of 
that gentleman's work on the Butterflies of the " Novara" voyage, and stating that 
the work was actually published (text and plain plates) at the time stated on the 
title page, and that the doubt as to the correctness of this, expressed by some 
English entomologists, was owing to the fact that coloured copies only were 
ordered from England, and these had to be prepared, thus accounting for the delay. 
The President also read a letter from Dr. Felder to the same effect. 
Mr. Smith read " Observations on the economv of some Brazilian insects" from
