THE ENTOMOLOGIST’S WEEKLY INTELLIGENCER. 
53 
gencer’ of the 13th of April, is, I believe, 
not uncomtnon. During the last two or 
three years I have met with similar in- 
stances, principally under the bark of the 
oak tree. In two instances I took the 
larviE from the trees and put them in 
some dead oak wood, having first bored 
holes in it, and put the whole into a 
large flower-pot, covering it over with 
perforated zinc. The larvse, in every 
case were of three sizes. They remained 
in the flower-pot for about eight months, 
and then disappeared, but where they 
went to I could never find out, neither 
did I find any pupae or dead larvae in 
the wood. As there appears to be a 
donbt whether the larvaa really does go 
three years in that state, I think it would 
be worth while for entomologists to give 
this matter their attention ; I shall cer- 
tainly do so, if I am fortunate enough to 
obtain some ova of the moth this season. 
I know of a birch tree where the trunk, 
for the height of about five feet, is com- 
pletely riddled by this larva, and is 
gradually decaying. I also have found 
them in the common chestnut; but in 
every case I have not succeeded in rear- 
ing a single moth, and I am not able to 
account for this, unless it is that I ought 
to give them green wood to live in, and 
not dead. — A. J. H. ; April 29, 1861. 
Cossus Ligniperda . — I would caution 
those who intend to breed this insect to 
mind the larvae are kept in close quarters, 
otherwise they are apt to prove trouble- 
some. When I commenced collecting, 
some years ago, before I was aware of 
the “ warmint’s ” vicious propensities, 
I put about fifteen or sixteen in a strong 
deal box, and supplied them with eim 
bark, thinking they would get on very, 
well ; but, to my surprise, when I paid 
my next visit I found most of them had 
emigrated, and, on a further search, they 
were discovered among some books, 
which they were devouring apparently 
with the greatest gusto. I have just 
heard a case of a geutleman, who, having 
found a full-grown larva, and being 
desirous of seeing what it would turn to, 
placed it in a cigar-box, which he left 
standing on a very nice piano. During 
the night it gnawed through the bottom 
of the box and the top of the piano, and 
when he went to look at it in the morning 
he found it had gone on a voyage of 
discovery into the inner regions. — W. H.

Ahana Myrtilli. — From my experience 
I should certainly say that the end of 
April is the usual time for the first ap- 
pearance of A. Myrtilli ; it is not double- 
brooded, although the early larvae may 
occasionally produce the perfect insect 
the same year. I bred it i'reely last 
season from larvae taken in September 
and October, 1869: the first imago ap- 
peared ou the 19th of April and the last 
on the 3rd of September. I have also 
taken it these last four years in April ; 
on the 16th of May, 1868, I saw it in 
abundance at Wickham Heathfield; on 
the 29th of April, 1860, I caught one in 
the lane near there; and on the 6th of 
May captured several on Shirley Com- 
mon, and at night, when sweeping the 
heath for larvae, found many in my net. 
This year I have also met with it at the 
same place, as I swept one on the 20th 
of April ; others were also taken at the 
same time in fine condition by my friends.

Anarta Myrtilli in April. — I took two 
specimens of this species on the 28th of 
last month, while sweeping for larvae 
on Shirley Heath. The occurrence of 
A. Myrtilli in April is not unusual; 
at the last meeting of the Haggerstone 
Entomological Society several gentlemen 
informed me they had often taken it in 
that month. — T. Huckexx, 26, Britannia 
Row, Islington ; May 14, 1861. 
Achroia Grisella. — I examined several 
bee-hives last autumn, in search of this 
species : I found one imago in a very 
dilapidated condition, some cocoons that
