.powder the smoke stupified the insects, and the nest was easily obtained. On 
examining the captured insects, they were found to correspond to the Linnsean 
character of Vespa sexcinctus, and also with the plate of the same insect given by 
Donovan. It likewise agrees with the description of Vespa Britannica of Leach, 
which in Stewarts Elements of Natural Historp^ is said to he common in Scot¬ 
land, but rare in England. V, sexcinctus is not given as a British insect in this 
work. Perhaps some of the readers of The Naturalist may be able to inform 
me what species of Wasp this really is.

CHAPTER OF CRITICISM. 
Mistake in a Review of Hewitson’s British Oology.” 
To the Editor of the Naturalist. 
]\Iy Dear Sirj*— I was much gratified with the perusal of the May number of 
The Naturalist.) and I fully intended ere this to have offered a few remarks upon 
it, but unavoidable engagements have prevented me from availing myself of an 
earlier opportunity. I have not yet received the number for the present month, 
as it was “ not out when the monthly periodicals came down on the first.; but 
I find, by the advertisement of it in the Magazine of Natural Historg, that it 
promises to be as interesting as the last numbers. I quite agree with H. E. H. 
(p. 88), that a chapter of criticism will be a valuable addition to the pages of 
such a chapter one of the essentials of a periodical, 
prov|ded aU personalities are excluded in the criticisms. 
In the review of Hewitson’s British Oology (p. 112), No. xxx. and xxxi., the 
three figures of plate 118 are described as belonging to Sylvia loquax^ whereas 
the two last figures represent those of S. sibilatriX) as will be seen on reference 
to the letter-press annexed. The eggs of S. loquax do not, according to my 
experience, vary very materially; that figured by Mr. Hewiison is a beautiful 
representation, and very characteristic. My specimens are very similar. I 
should like to have seen an additional figure of the egg of S. eihilatrix. Several 
We beg to caution our readers against this most dangerous method of taking the nest, a method 
which has lately caused two very serious accidents in our neighbourhood. In one instance the in¬ 
dividual—a near relative of the Editor’s—received so violent an injury that the hand was obliged 
to be amputated next day; in the other the whole arm was sacrificed. In both cases the vessel 
containing the gun-powder burst in the hands of the operators.—Em 
i Our numbers are invariably in town several days before the first of each month.— Ed,
