Setina. Speyer has published some very interesting remarks on this genus,
with special reference to S. aurita and ramosa, which he considers to be
almost, but not entirely, perfectly developed species. The three species
which he considers the main stems of the genus are irrorella (with freyeri
and andereggii), roseida (with kuhlweinii, alpestris, melanomos, wAfiavicans),
and aurita (with ramosa).
The following changes take place in Setina ramosa at a considerable altitude
:—1, the size diminishes; 2, the covering of the body is rougher and
more matted, from the hair becoming longer and thicker; 3, in proportion
to the thickening of the covering of the body, the thickness of the scaling of
the wings diminishes; 4, the colour is generally paler; 5, the black markings
are usually more extended; 6, the shape of the wings is altered.
Corresponding changes take place in the mountain-forms of various species,
while other species are unaffected by the altitude. In conclusion, Speyer
attempts to explain the object of these modifications in moimtain-insects,
