imported specimen, as we are forty miles from London, and 
sixteen or seventeen from Shoreham,—our nearest seaport,— 
to which, 1 think, no American ships come. If you can 
furnish any particulars as to larva, food-plant, chrysalis, and 
their respective seasons, which may help me in my search for 
it next year, I shall be much obliged.

Danais Archippus. By J. JENNER WeEtR, Esq., F.L.S. 
THE specimen of Danais Archippus, which Mr. Crallan 
was kind enough to exhibit to me, and which forms the 
subject of the above communication, presents the appearance 
of a very fine female of the normal North-American type of 
the species. It had apparently but just emerged from the 
chrysalis, and there can be but little doubt that the larva had 
been reared in the neighbourhood. The accidental appear- 
ance of a North-American Lepidopteron in this country 
would, under ordinary circumstances, be of trivial importance, 
but there are reasons in the present case for attaching some 
value to the fact above recorded. Danais Archippus is a 
well-known American species, found as far north as Canada, 
and by Mr. Bates as far south as the Amazonian district 
(vide Trans. Linn. Soc., vol. xxxiii., p. 516). It has lately 
become naturalised in New Zealand and Australia, and Mr. 
Butler, of the British Museum, informs me it has been 
received from New Guinea; a specimen has also this year 
been taken near Neath, in Wales, as recorded in the ‘ Ento- 
mologist’s Monthly Magazine, 1876 (p. 107). It is, therefore, 
found distributed over a large part of the earth’s surface, in 
three of the six Zoogeographical regions now generally 
recognised, viz. the Nearctic, Neotropical, and Australian ; 
itis by no means improbable that the species may become 
also naturalised in this the Palearctic region. It becomes, 
therefore, important that its earliest appearance in this 
country should be recorded. A full account of the insect is 
given by Mr.C.V. Riley, the State Entomologist of Missouri, 
in his Third Annual Report, 1871 (pp. 143—152), and a copy 
of his woodcut of the full-grown larva is given herewith, in
