England,” as lie had not taken it in 
Belgium and it was only known in the 
South of France. Since then he has 
taken it in Belgium. The insect is 
not rare in heathy and boggy districts 
but very local. J. C. Dale. Gian.

Lepidoptera. 
Relaxing with laurel leaves. The 
Revd. F. 0. Morris, does not find 
laurel leaves answer. I do ; — but it 
requires some attention. The laurels 
must be well bruised and kept close 
in a glass jar with stopper as the 
fumes otherwise evaporate and become 
mouldy and useless. They may be 
kept good for twelve months. There 
is one advantage of laurel leaves over 
damp flannel, sand etc ; — especially 
with dragon flies and some others. 
If damp 'flannel, etc be used the 
insects become rotton and fall to 
pieces, but not so with laurel leaves- 
I relaxed a great many Libettulce for 
the British Museum, and set them 
next day, and they do very well. Id. 
Abundance of the larva of Lyonetia 
Glerhella on Birch. On the 27th. of 
last July I met with a young Birch 
growing in Headley Lane, almost 
every leaf of which was mined by this 
larva, some leaves being tenanted by 
no less than four larvae. The larvae 
were in all stages of growth from the 
first hatched to the full fed. Several 
of the larvae having effected their es- 
cape from the interior of the jars, 
spun their cocoons on the outside of 
the same. Would that all micro- 
lepidopterous larvae were equally 
considerate ! 
They commenced constructing their 
cocoons on the 28th, and, on the 7th. 
of the following month the first 
Imagos made their appearance. 
I noticed, that a faint lemon scent 
arose from the jars containing the 
larvae. Chas Healy, 74 Napier

Number of Entomologists in Eng- 
land. While fully agreeing with 
your remarks in the leading article of 
the “ Entomologist ” for January 
10th. I think you are, and I hope 
you are, much mistaken as to the 
number of Entomologists in the coun- 
try. I say this with the fact before 
me, or my mind, that I noticed 
some year or so ago, on the title 
page, either of the “ Annual” or the 
“ Manual of Butterflies and moths,” 
that it was the “fourth thousand ,” 
and it is no disrespect to either of 
those works to say, that no-one who 
was not an Entomologist would 
think of buying them. Revd. E. 0.
