failed in breeding them. Most of the 
Nepticulce are said to be double-brooded ; 
my short experience inclines me to the 
opinion of a succession of broods. From 
J une to October the larvae of several 
species are always to be found. * * * * 
Of all the Nepticula, Weaveri is the most 
extraordinary. The singular appearance 
of the leaf of Vaccinium Vitis-Idcea when 
the larva is full fed, with the cocoon in- 
side the leaf, and elongated and lying 
between an upper and lower layer of silk, 
is a marvel of workmanship. The insect 
is exceedingly difficult to rear. I col- 
lected a sufficient number of full-grown 
larvae, had they produced moths, to have 
supplied most collections with specimens. 
I bred some three dozen only, which 
were most irregular in their appearance, 
from June 21 to August 24. Had Ich- 
neumons made their appearance it would 
have been satisfactory in accounting for 
my mishap. On opening the cocoons the 
great bulk contained a shrivelled larva, 
which had apparently died of utter ex- 
haustion in spinning these astounding 
cocoons.” — From the ‘ Zoologist ’ for

Nepticula on Convolvulus Arvcnsis . — 
We found these larvae on the 26th of 
September, at the edge of a field. — Oxr-

Nepticula on Potentilla Tormentilla . — 
We found the mines of this species a few 
days ago, at the margin of a wood. —

Nepticula on Potentilla Tormentilla . — 
I had met with this larva at West Wick- 
ham Wood, and between Barnstaple and 
Bideford ; the mine is more of a blotch 
than that of Aurelia, and has no resem- 
blance to that of Arcuata. — H.T. Stain- 
ton ; Nov. 7. 
Another Nepticula ! — In the middle of 
October we found, under hedges at the 
skirts of a wood, a Nepticula mine in the 
leaves of Agrimonia Eupatoria, very 
abuudant. The larvaj had almost all 
assumed the pupa slate, the cocoon being 
invariably inside the mine, and generally 
in one of the serratures of the leaf. This 
can hardly be N. aurella, for, in the first 
place, we have never met with that spe- 
cies (so common in England) here, and, 
secondly, it is not known to change in- 
side the mine. — Friedrich Hofmann, 
Ratisbon ; October 30. 
A new Nepticula Larva. — I have found 
a larva mining in blotches in the leaves of 
Agrimonia Eupatoria. In England I 
believe the larva of N. Aurelia has oc- 
curred on this plant, but that no doubt 
makes a gallery. On the 25th of October 
I found near Zurich a yellowish larva 
mining in brown blotches the Agrimonia, 
and changing within a flat brown cocoon. 
At the same time Herr Hofmann met 
with this Agrimonia- miner at Ratisbon ; 
but, singularly enough, the larvae I have 
received from Ratisbon changed to pupa 
within the mine, those I found here have 
formed their cocoons outside the mine. —

Lithocolletis insignitella. — We first 
found the mines of this species on the 
5th of June, at the edge of a fir wood, in 
the leaves of Trifolium alpestre and 
medium; they specially frequent those 
plants which are most sheltered. At the 
end of September we found the second 
brood in the same locality, and under the 
same circumstances. — Ottmar H ofma n n, 
Ratisbon; October 10. 
Carbonate of Ammonia. — During the 
past season, I and a young friend 
have made trial, for killing Lepidoptera 
and small Coleoptera, of the carbonate 
of ammonia, instead of liquid ammonia 
or laurel leaves, and which has fully 
answered our expectations. The car- 
bonate lias the preference of the liquid, 
as from it no damp vapour collects in the 
bottle, being also cheaper and far safer 
to be placed in the hands of the young. 
The laurel leaves are often difficult to 
be obtained, and therefore not readily 
accessible. The best way of placing the 
carbonate of ammonia in the bottle is
