appears to be a new species of a very 
pale grey. — I bid. 
Neplicula Turicemis bred. — I have 
bred this in plenty from larvae in beech 
leaves: the mines were so similar to those 
of Tilyrella that I had collected them 
supposing them to be that species. — 
Ibid. 
Lithocollelis insignilella. — I have bred 
several of this from the trefoil leaves 
sent me by Herr Hofmann, of Ratisbon 
(see Intell. iii. p. 59), and I also found 
the larvae here: the perfect insect is 
closely allied to L. Bremiella. — Ibid. 
Spiculce. — I dare say some of your 
readers will remember the notice in the 
‘ Intelligencer’ of last year (No. 29), of 
the appearance of spiculce , or needle-like 
crystals, on E. Lanestris and T. gnthica, 
in a tin laurel-box : a request was made 
for explanation, but none, I believe, was 
offered. I have found these spiculce this 
year on a number of T. stabilis and in- 
slabilis ; they frequently joined a leg to 
a wing, or any two parts not far distant 
from each other. The insects were all 
bred, and were put into the box about 
twenty-four hours after they made their 
appearance, and the crystals, which were 
all extremely thin and fine, but in some 
cases broader than others, were formed 
in about three days: none of the insects 
were free from them. I first observed 
them on the 8th of March, and they con- 
tinued to form on the insects put into the 
box till the 14th, since which time none 
have appeared, though I have used the 
same box and put into it the same sort 
of insects. My laurel-box is of tin, and, 
as the laurels are now rather innoccuous, 
I drop into it, from time to time, a little 
essence of bitter almonds. Perhaps some 
of your readers may explain the pheno- 
menon. Has the state of the atmosphere 
anything to do with them ? — J. G. Gren- 
fell, Rugby ; March 29. 
Catalogue of European Lepidoptera . — 
The most complete Catalogue of Euro- 
pean Lepidoptera is that which I pub- 
lished in 1855. I have forwarded a sup- 
ply on sale to Mr. Newman; the price 
(post free) will be lOd. In this Cata- 
logue, the dot prefixed to the names of 
certain species indicates that I have du- 
plicates or can procure specimens of 
them, and the figures following those 
names denote the price of a specimen in 
pence. Thus: “ . Lathonia 1” signifies 
that I can procure specimens of Lathonia , 
and the price will be one penny each. I 
can also procure specimens of several 
species which have not the dot prefixed. 
Those who are not conversant with my 
nomenclature will find my ‘ SynoDymia 
Lepidoplerorum ’ serviceable; the price 
is 7s. Parcels to England I cannot pre- 
pay ; parcels to Ireland must be prepaid 
here, but I charge the cost in my account. 
Letters to me (weighing under half an 
ounce) must be prepaid by affixing 8 d. 
in stamps: a single penny stamp is of no 
use ! Those who wish to correspond 
with me should first send me a list of 
what they have to spare. My wants, in 
the first volume of the ‘Manual,’ are 91, 
97, 98, 111, 151, 201, 227, 230, 241, 
245, 246, 247, 252, 256, 275, 284, 311, 
326, 327, 344, 353, 404, 448, 465, 480, 
489. Those who cannot give references 
to a banker here must remit the cash, or 
forward their insects to me, before I for- 
ward miue to them. — Dr. Herrich- 
Schaffer, Ratisbon, Bavaria ; Feb. 9. 
COLEOPTERA. 
Ants’ -nest Beetles. — Yesterday I made 
my first essay at examining an ants’ nest 
for the tenant beetles, and was delighted 
with the new forms of life and habit re- 
vealed to me. I found a nest of Formica 
rufa, about a small cart-load, and set 
myself down to examine it. The occu- 
piers, or at least some of them, were 
lazily clearing out the entrances, re- 
minding one of the preparations made 
for his expected guests by the landlord 
of a Highland hostelry; but I could not 
sec any hexapod lodgers in this hotel:
