er, on the clothes of human beings, and in various
other ways, which will readily suggest themselves. Dr. Gardner, after a
careful consideration and minute examination of estates, arrived at the
conclusion, that all remedies suggested up to that time had utterly
failed, and that none at once cheap and effectual was likely to be
discovered. He seems also to have been of opinion that the insect was
not under human control; and that even if it should disappear, it would
only be when it should have worn itself out as other blighte have been
known to do in some mysterious way. Whether this may prove to be the
case or not, is still very uncertain, but every thing observed by Dr.
Gardner tends to indicate the permanency of the pest.

_List of Ceylon Insects._

For the following list of the insects of the island, and the remarks
prefixed to it, I am indebted to Mr. F. Walker, by whom it has been
prepared after a careful inspection of the collections made by Dr.
Templeton, Mr. E.L. Layard, and others: as well as of those in the
British Museum and in the Museum of the East India Company.[1]

[Footnote 1: The entire of the new species contained in this list have
been described in a series of papers by Mr. WALKER in successive numbers
of the _Annals of Natural History_ (1858-61): those, from Dr.
TEMPLETON'S collection of which descriptions have been taken, have been
at his desire transferred to the British Museum for future reference and
comparison.]

"A short notice of the aspect of the island will afford the best means
of accounting, in some degree, for its entomological Fauna: first, as it
is an island, and has a mountainous central region, the tropical
character of its productions, as in most other cases, rather diminishes,
and somewhat approaches that of higher latitudes.

"The coast-region of Ceylon, and fully one-third of its northern part,
have a much drier atmosphere than that of the rest of its surface; and
their climate and vegetation are nearly similar to those of the
Carnatic, with which this island may have been connected at no very
remote period.[1] But if, on the contrary, the land in Ceylon is
gradually rising, the difference of its Fauna from that of Central
Hindustan is less remarkable. The peninsula of the Dekkan might then be
conjectured to have been nearly or wholly separated from the central
part of Hindustan, and confined to the range of mountains along t
