Several Members said that, as they understood the popular account of the Ano- 
bium, the tapping was not represented as being external ; it was the fact of the noise 
being heard, whilst nothing was visible which could be suggested as producing it, that 
caused the ignorant to dread the so-called death-watch. 
The Rev. J. Greene exhibited eight moths bred by him from pupe which had 
been sent to him by Mr. Batty, of Sheffield, as pupe of Acidalia subsericeata: from 
these had emerged one moth which was undoubtedly A. subsericeata, one which did 
not agree with any species known to him, and six which were clearly referable to the 
recently-described A. mancuniata of Dr. Knaggs. 
Mr. F. Moore produced for inspection a series of well-executed plates of the 
insects of N. America, engraved by Mr. Townend Glover, of the State Department of 
Agriculture: these plates were a portion only of an extensive series which Mr. Glover 
has in preparation for his forthcoming work on the Insects of North America, and are 
illustrative, in the different Orders, of many of the species in their various stages of 
transformation ; accompanying them was also a series of plates illustrating the insects 
destructive to the cotton plants, orange and lime trees, potato, &c., in America. Mr. 
Glover has been officially engaged for some years past in the study of the insects 
injurious to vegetation in America, and the results of some of his labours have been 
published in recent volumes of the American Patent Office (Agricultural) Reports, 
Mr. Janson also produced twenty-four plates of the same series, illustrative of the 
Coleoptera of North America. 
Mr. C. A. Wilson, of Adelaide, communicated another instalment of his “ Notes 
on the Buprestidae of South Australia.” 
Prof. Westwood exhibited three new Longicorn beetles, for which he proposed the 
names of Cantharocnemis Livingstonii (from Zambesi), Cantharoctenus Burchellii 
(from Damara-land), and Cantharoplatys Felderi (from the White Nile). The two 
latter were clearly allied to Cantharocnemis, but differed therefrom and from one 
another; he therefore proposed for them different sub-generic names, but in so doing 
had endeavoured, by the form of name selected, to show their subordination to or 
dependence upon the primary genus Cantharocnemis. 
The President was unable to see the advantage of giving distinct names to sub- 
divisions which were admittedly not genera. In the present case, by what name was 
the insect to be known? Cantharocnemis Felderi? or Cantbaroplatys Felderi ? or 
Cantharocnemis (Cantharoplatys) Felderi? If by the first, why introduce the name 
Cantharoplatys at all? If by the second—then, either Cantharoplatys is in fact 
treated as a genus whilst it is confessedly not of generic value, or the fundamental 
rule of the binomial nomenclature, that an insect is known by the names of the genus 
and species to which it belongs, is infringed. If by the third, the binomial nomen- 
clature is abrogated, and a trinomial system introduced, without any advantage to 
compensate for its greater cumbrousness and difficulty of retention in the memory. If 
a newly-discovered form differed so much from previously-known forms as to be 
incapable of admission into any established genus, it must of course be described as a 
new genus and under a new name; but in his opinion there was not any subordinate 
or intermediate stage between the species and the genus to which it was either neces- 
sary or desirable that a distinct name should be applied. 
Mr. Stainton thought that, in the state at which Natural History had arrived, and 
owing to the immense variety of forms which had been and would doubtless continue
