yellow upon them. It also differs much on 
the under side; perhaps the best cha- 
racter there is one pointed out to me 
by Dr. ICnaggs: in Complana there is 
always a costal streak on the under side 
of the inferior wing, from the apex to 
the base, of one uniform width, or nearly 
so; whereas in the species from our 
mosses the same streak is broad for 
nearly one-third of the wing, when it 
either disappears abruptly or is only 
continued to the base as a very faint 
narrow streak. 
From Complanula it differs in being 
less rounded on the costa, and also in 
the collar being continued tinicolorous 
with the costal streak, as in Complana ; 
the costal streak varies much in its 
breadth at the apex, sometimes being 
carried through of an equal width, as in 
Complana, at others approaching the 
form so invariably seen in Complanula ; 
but it always wants the ample yellow 
under wings of that species. Formerly 
there was a L. depressa in our lists ; this 
species is figured and described as with 
a very broad costal streak carried straight 
out below the apex of the wing, and 
with suffused under wings. Can this be 
our species? No; partly because it is 
said to have a straight costa, whilst ours 
has a rounded costa.; and, secondly, be- 
cause, whilst it is figured in “ Westwood 
and Humphrey” (p. 20, f. 14), with a 
broader costal streak than Complana, 
our insect has a narrower and less 
straight mark than either. 
What then can our moss insect be ? 
My opinion is that it is neither one nor the 
other of the above species, and I there- 
fore propose to call it * Lilhosia Sericea 
from its peculiar silky appearance.

CRITICAL OBSERVATIONS ON SOME 
OF THE SPECIES OF THE GENUS 
COSMOPTERYX. 
BY H. T. STAINTON. 
We now turn our attention to the 
exotic species of the genus Cosmopteryx. 
Dr. Clemens has described, in the ‘ Pro- 
ceedings of the Academy of Natural 
Sciences of Philadelphia,’ a Cosmopteryx 
Gemmiferella, which is intermediate be- 
tween C. Scribaiella and the Druryella 
group. The essential characters of this 
species are — 
“ Anterior wings dark greenish brown, 
with three short longitudinal silvery 
streaks near the base (these represent the 
fascia we find in Eximia and Schmidi- 
ella), with a reddish orange fascia, edged 
with silvery violet, in the middle (this 
fascia is considerably broadest on the costa, 
its hinder margin being formed by two 
silvery violet spots, u'hich are by no means 
opposite) ; at the apex is a short silvery 
white scale, preceded by a violet silvery 
spot, with which it is not connected .” 
Dr. Clemens has very liberally for- 
warded me six specimens of his Cos- 
mopteryx ; but I find, on close examina- 
tion, that only four of them truly belong 
to Gemmiferella, the other two being 
manifestly a distinct though closely allied 
species, which, though possessing the 
three short longitudinal streaks near the 
base in place of the fascia, differs in the 
following respects: — The ground-colour 
of the anterior wings is darker, the orange 
fascia is paler, not so reddish, its margins 
are pale golden, instead of silvery violet, 
and its hind margin is almost straight, 
and thus very different from that in 
C . gemmiferella ; finally, the apical streak 
is continuous, not interrupted, and of a
