[3] Captain Fitz Roy informs me that in April (our October), the leaves
of those trees which grow near the base of the mountains change colour,
but not those on the more elevated parts. I remember having read some
observations, showing that in England the leaves fall earlier in a warm
and fine autumn than in a late and cold one, The change in the colour
being here retarded in the more elevated, and therefore colder
situations, must be owing to the same general law of vegetation. The
trees of Tierra del Fuego during no part of the year entirely shed
their leaves.
[4] Described from my specimens and notes by the Rev. J. M. Berkeley,
in the Linnean Transactions (vol. xix. p. 37), under the name of
Cyttaria Darwinii; the Chilean species is the C. Berteroii. This genus
is allied to Bulgaria.
[5] I believe I must except one alpine Haltica, and a single specimen
of a Melasoma. Mr. Waterhouse informs me, that of the Harpalidae there
are eight or nine species--the forms of the greater number being very
peculiar; of Heteromera, four or five species; of Rhyncophora, six or
seven; and of the following families one species in each:
Staphylinidae, Elateridae, Cebrionidae, Melolonthidae. The species in
the other orders are even fewer. In all the orders, the scarcity of
the individuals is even more remarkable than that of the species. Most
of the Coleoptera have been carefully described by Mr. Waterhouse in
the Annals of Nat. Hist.
[6] Its geographical range is remarkably wide; it is found from the
extreme southern islets near Cape Horn, as far north on the eastern
coast (according to information given me by Mr. Stokes) as lat. 43
degs.,--but on the western coast, as Dr. Hooker tells me, it extends to
the R. San Francisco in California, and perhaps even to Kamtschatka. We
thus have an immense range in latitude; and as Cook, who must have been
well acquainted with the species, found it at Kerguelen Land, no less
than 140 degs. in longitude.
