OBSEEVATIONS. 
Porlhesia Chrysorrhcea and Eriogaster 
Lanestris. — I hare not met with the 
larvae of these species, though I have 
recently visited the locality where last 
year, earlier than this, I took them by 
hundreds. — B. W. Weight, 4, Gloucester 
Terrace, Victoria Park Road ; May 27,

Cosstis Ligniperda . — Much has lately 
been said about this insect, and much 
doubtless remains which might be said. 
It is by far the strongest larva which I 
have had anything to do with, and often 
succeeds in lifting up the lid of the box 
in which it is confined ; it can also 
squeeze itself through so small a hole 
that 1 have often been puzzled in finding 
out by what means the insect made its 
exit. After they have made their escape 
they sometimes creep under a mat (I 
have twice found them in such a place), 
and make themselves a slight cocoon. A 
friend of mine kept some of these larvae 
at the top of his house ; one escaped, and 
was soon after found at the bottom of 
the house. It will be seen by this that 
they can perform rather long journeys, 
though perhaps it fell part of the way. 
I now keep them in a tin box, through 
which they cannot bore. “A. J. H.” 
doubtless failed in breeding his larvae, 
because he did not give them green 
wood: I have never found them in any 
other than a living tree. I think the 
best way to breed them is to place them 
in sawdust, and then to supply them 
frequently with small pieces of living 
wood; otherwise they may be placed in 
a large piece of fresh wood, which must 
be occasionally moistened, for the reason 
stated by Mr. Stainton {ante p. 4) with 
regard to the larvae of H. Majorella and 
D. Oliviella. I have bred some larvae 
since January, which thrive well under 
the first method; during the winter they 
spin a strong cocoon, but come out in 
the spring, or if placed in a warm room. 
I have generally found trees more or less 
inhabited by these larvae, according as 
the trees stand alone, or in company 
with others. A tree standing alone, if it 
has any, will for the most part be found 
to contain a very great number. — ;E. S. 
Dewick, Blackheath ; May 22, 1861. 
A Mining Larva in the Leaves of 
Anemone nemorosa. — The weather being 
propitious, and M. Fologne proposing an 
excursion to the Forest of Soignies, I 
thought I could not do better than try 
my luck there, more especially as M. 
Fologne had much raised my expecta- 
tions by showing me some hexapodal 
larvas which were mining in birch leaves, 
sometimes as many as ten or twelve in a 
leaf, each in a separate mine, the said 
mine being a blotch of irregular form ; 
and further he showed me that these 
hexapodal larvae (apparently utterly des- 
titute of ventral prolegs) soon came out of 
the leaves, and formed cases of irregular 
form, thorough bivalves, but of no de- 
fined outline, thus totally distinct from 
anything that the larvs of Incurvaria, 
as hitherto observed, construct. We had 
both suspected these larvae might be 
Coleopterous (but we dare not say so, for 
fear of each laughing at the other); 
moreover, I know of no Coleopterous 
larva that constructs a bivalve case. 
The Forest of Soignies, which is of 
very considerable extent, its longest 
diameter being about twelve English 
miles, lies to the south of Brussels, and 
is easily reached by the Luxembourg 
Eailway, the second station on that line, 
Groenendaie {Anglice Greendale) being 
in the heart of the Forest, which consists 
principally of beech trees, but interspersed 
with firs, poplars and a few other trees, 
and with numerous bushes of alder, horn- 
beam, dogwood, &c. The growth of low 
plants is very varied, and in some parts 
Epilobium anguslifolium grows in great 
profusion ; on this we found a few larvie 
of Laverna conturbatella, but L. Rasch-
