or two specimens of this insect, if they would examine the trunks of oak trees in the 
neighbourhood at dusk, they would, from my experience, most probably be rewarded 
by the capture of a great many more specimens of this interesting insect. 
I have noticed a Calosoma closely allied to CO. sycophanta, in great quantities, 
and under the same conditions, in the woods in Delaware and Maryland, U.S. I 
think, without doubt, that they ascend the trees at night in search of food, feeding 
upon the small caterpillars which generally abound upon oak trees in the spring, 
and that they return in the early morning to hide. 
I might say that in Buddon Wood the time of its appearance is about the last 
week in May or the commencement of June. I have just taken Auchenia quadri- 
maculata in great plenty.—Harry HoryoaKk, 45, Humberstone Gate, Leicester, 
July, 1871. 
A List of the Odonata (Dragon-flies) occurring in the neighbourhood of Epping.— 
Having captured a large portion of our British Libellule in the neighbourhood of 
Epping, I thought a list of them might be interesting to some of your readers. I 
regret to say that some of the best localities are destroyed, and I am not certain 
that all the species enumerated are now to be found here. The nomenclature is 
that adopted by Mr. McLachlan, in his valuable catalogue of British Newroptera.
