NATURAL HISTORY OF THE 
TINEINA. 
On a probable new Cosmopteryx. 
I called attention, in June last (Intel. 
No. 193, p. 83) to a probable new spe- 
cies of the genus Cosmopteryx, which 
Herr Hofmann, of Katisbon, had bred 
from a larva which mined the leaves of 
a grass, Ilierochloc Australis. This larva 
I had received from Herr Hofmanu in 
August of the previous year, but had 
then mistaken it for an Elachista, and 
I thus noticed it among the Enigmas in 
the ‘ Annual’ for 1860, p. 152: — 
“ 80. An Elachista larva collected 
by Herr Hofmann at Ratisbon early in 
October [this is an error, it should have 
been in AugusC] ; it mines the leaves of 
Hierochloe Australis, making straight, 
rather narrow mines, but eventually 
several side by side, so as to occupy 
nearly the whole width of the leaf; the 
mine is perfectly clean, the excrement 
being excluded through a hole in the 
cuticle." 
This last-named character is very im- 
portant, as therein the habit differs from 
that of an Elachista larva, none of 
which, so far as I can remember, eject 
any of their excrement. A grass leaf 
mined by a Lepidopterous larva, but 
containing no excrement within the 
mine, would therefore be indicative of a 
Cosmopteryx. The personal appearance 
of the Hierochloe larva showed nothing 
unusual; the larva was yellowish green, 
with the dorsal vessel greener, and with 
the head and second segment black. 
Immediately on the appearance of the 
notice iu the ‘ Intelligencer’ of June 16th, 
Mr. Thomas Brown forwarded to me for 
inspection a Cosmopteryx, with which 
I had been much struck when looking 
through his collection at Cambridge two 
years ago. 
Mr. Brown wrote as follows: — 
“ 13, King's Parade, Cambridge, 
June 19, 1860. 
“ Dear Sir, — The mention of PJximia, 
in last week’s ‘ Intelligencer’ has re- 
minded me of an insect I took some time 
ago in our fen. I have been told that 
it is Eximia, and that the larva feeds on 
hops; but there were no hops within a 
mile of the open fen where I took it,
