COLEOPTERA. 
To Mr. Hogan’s “ Catalogue of Coleoptera found in the 
neighbourhood of Dublin/’ published in the Zoologist, I 
must also acknowledge myself indebted for many novelties. 
Mr. Wollaston’s “ Insecta Maderensia” has also afforded 
its quota, and I may, perhaps, here be permitted to observe 
that at least three-fourths of the genera of Coleoptera com* 
prised in Mr. Wollaston’s work, and to which order the 
present volume is restricted, are indigenous to Great Britain; 
that their characters have all been re-wrought from actual 
re-investigation, and that the student of British Coleoptera 
will, in the pages of this magnificent book, find ample and 
satisfactory details of upwards of one hundred and fifty genera 
of British Beetles. 
In the “ Transactions of the Entomological Society of 
London,” of which the second part of the eighth volume 
has just made its appearance, and which embrace a period 
of no less than twenty years, only three papers have fur¬ 
nished matter for the present list. 
Nearly two hundred and thirty species, none of which, it 
is presumed, are given in Mr. Stephens’s “ Manual of British 
Beetles,” are comprised in this list; if to these we add those 
extant in our cabinets, but which have not been recorded, 
and which certainly do not fall far short of a hundred, it 
results that three hundred and thirty species have been dis¬ 
covered during the last fifteen years, or at the rate of twenty- 
two per annum, and, judging from the lists of the Coleop¬ 
terous productions of countries occupying a geographical 
position very similar to our own, there exists ample room 
for at least a corresponding increase during the succeeding 
fifteen years. 
I will conclude by remarking that the brief period allotted 
me for the completion of my task, and which has been a c * 
complished during the short and uncertain intervals afforded 
by more urgent occupations, has precluded me from referring
