state, it cannot hastily redress ils injuries 
bv putting on its old frock, and so it fre- 
quently happens that the poor thing dies 
of exposure; a sad calamity if it he a 
rarity. However, as some day, no doubt, 
some one will turn up conspicuella by 
the score, it will be as well for the lucky 
fellow to bear iu mind that conspicuella 
is wanted here in more senses than one. 
Palliatella : this larva has not, I be- 
lieve, been met with here for several 
years. The great big flaps to the case 
readily distinguish it from Analipennella , 
and, like that species, it is polyphagous. 
Currucipennella : also in a pistol- 
shaped case on oak, hornbeam, &c., but 
generally rather a rarity in this country. 
Saturatella . Mr. Burton found a case 
last year, at the beginning of July, “ on 
the common broom, on the road leading 
from Llangollen to the limestone rocks, 
where Ashworthii is found: it appeared 
tolerably abundant.” I hope to receive, 
from some of the North Wales tourists, 
some of these larvae this summer, so as to 
establish, by breeding them, whether 
they are related to saturatella or not. 
Murinipennella : the larva will be 
found the middle or end of June on the 
seeds of the Luzula. 
Badiipennella : this ash-feeding larva, 
in its pretty little case, I expect to find 
myself; but in case my expectations are 
vain, I shall be very glad to hear that 
some one else has got a store of it in case 
of need. — H. T. Stainton ; April, 1857.

Whilst on the subject of Psyche Helix, 
Von Siebold gives the following very in- 
teresting little note. 
“ Besides Psyche Helix, there are some 
other insects, whose larvae make cases in 
the form of a snail-shell. In the genus 
Psyche itself there occurs another spe- 
cies, the caterpillars of which, like those 
of P. Helix, bear about with them a 
spirally-twisted case. By the kindness 
of Professor Zeller, of Glogau, and Dr. 
Rosenhauer, of Erlangen, I possess two 
earth-coloured, snail-like cases with per- 
fectly flat convolutions, found in Sicily 
and Spain. They are nearly three times 
as large as the cases of Psyche Helix, 
and from their different form and size 
belong to another species, to which I 
will give the provisional name of Psyche 
planorbis. 
“ In the family of the Phryganidce 
also, larvae occur which form a spirally- 
twisted domicile. I saw several of the 
habitations of this insect in Bremi’s 
collection, at Zurich, partly collected in 
Corsica and partly on the Lake of Como. 
Bremi has given the name of Helico- 
psyche Shuttleivorthi to the questionable 
Phryganidan from which these spiral 
cases are derived ; and many specimens 
of a similar smaller case have been sent 
to him from a brook in Porto Rico, the 
inhabitant of which Bremi has named 
Helicopsyche minima. A principal dis- 
tinction between these Phryganidan do- 
miciles and the spiral cases of Psyche 
consists in the fact, that whilst in the 
case of Psyche Helix extremely fine 
grains of sand are stuck as a coating 
upon the outer surface of the white web 
of the case-walls, in Helicopsyche the 
walls of the habitation are formed directly 
and solely of larger, polygonal particles 
of sand, closely cemented together from 
within and without That the 
Helicopsyche cases are really produced 
by a Phryganidous insect, I ascertained 
from the contents which I extracted from 
the two cases Helicopsyche minima still 
furnished with opercula. These con-
