CHAPTER OF CRITICISM.

4. Miss Jermyn in her Vade Mecum* mentions “ Bedfordshire,” and u St. 
Osyth, Essex,” as localities for this species; on what authority she has not 
thought it necessary to inform us, and consequently I can only refer to them 
with suspicion, which is increased by our fair Aurelian adducing in her observa¬ 
tions on P. podalirius the capture of a species by Mr. Hawkins in the New- 
Forest, in 1827. The said New-Forest specimen having been long, and, I had 
thought, previous to reading the Vade Mecum , universally, known to have 
originated in a mistake ! Miss Jermyn is indeed, in more cases than one, much 
too careless in'admitting localities. For instance, the student is informed in her 
u synoptical table” at p. 59, that Doritis Apollo occurs in the Island of Lewis ; 
this locality having proceeded from the supposition (long since exploded) that a 
few continental specimens in the possession of Lord Seaforth were captured there. 
I have now stated the case pro and con ; and shall be obliged by any of your 
readers furnishing information on points 1, 3, and 4 of the above remarks; and 
especially by Mr. Head noticing the first. 
I remain, 
Faithfully yours,

* The Butterfly Collector's Vade Mecum , bj Miss Jermyn (now Mrs. Ford), Ipswich (3rd 
edit.), 1836.—Not having then seen this work, I omitted noticing it in the paper on “ Entomolo¬ 
gical Bibliography” (III., 19). It is neatly got up, and displays a tolerable development of the 
organ of Order on the part of the authoress. But this is almost all that can be said in favour of 
it, as throughout, I am sorry to say, it is a compilation, and in many cases an incorrect one. One 
or two errors are pointed out above, and in addition I shall only remark that several insects are 
given as “ ascertained British species according to Mr. Duncan respecting which that gentle¬ 
man in his British Butterflies expresses himself very doubtful (e. g., Dor. Apollo , Pol. alcon , &c.). 
The authoress congratulates herself that “ this little work appears to have led to the publication 
of Brown’s Book of Butterflies with which, and the ex-professor’s Conspectus , it may certainly 
be laid on the shelf. Mr. Duncan’s vols. in the Naturalist's Library are worth the Vade Mecum 
and the Captain’s Book put together.—I am afraid I shall be accused of ungallantry •, but it is the 
work I remark upon ; and my observations are the more necessary as it has been quoted by some 
as an authority.
