of the insect could be readily obtained ; 
the Ollier, in supposing that there would 
be little demand for the insect; but no 
hoax was intended. 
A. W. C. — Keep plenty of camphor in 
the drawers. 
R. B. P. — Saw-flies; yes. Trichiosoma 
lucorwn ; see Intel, vol. ii. p. 134, the 
speech of T. lucorum, at the “ Important 
meeting of saw-flies.” 
OBSEKVATIONS. 
Sound produced hy the Pupa of 
Acherontia Atropos. — There are probably 
few who have bred the Death’s Head 
moth that have not heard the peculiar 
sound emitted by that insect when 
touched or irritated. I have myself ob- 
served it in all that I have bred this 
season, in both sexes, and loudest in 
those that have emerged in a crippled 
state. That the larva also can produce 
the sound is proved by a notice to that 
effect from one of your correspondents in 
the ‘Intelligencer’ of the 18ih of Sep- 
tember ; but I was not aware, until a few 
days since, that the pupa can produce 
a similar sound when handled. Ex- 
amining some pupae on Friday last (one 
of which, from its dark appearance, 
seemed as if the moth was ready to 
emerge), I was surprised to find that on 
taking it into my hand the same sound 
was made as by the perfect insect, 
although slightly subdued: this was 
beard by friends as well as myself, and I 
have since continued to notice it on two 
or three occasions, but not invariably, 
when taken out of the flower-pot in 
which it is deposited. — James Dutton,

Larva of Antiihesia prcelongana. — As 
no mention is made of this larva in the 
‘ Manual,’ I beg to say that it is green, 
feeds on birch, and is full fed from the 
beginning to the middle of October; it 
spins up between two united leaves, and 
lays in pupa during the winter, the 
imago appearing the following May. I 
met with it at West Wickham on the 
2nd of May, when searching for Car- 
melita, and took it again on the 3rd and 
27th of June, in fine condition, so that 
its appearance would appear to last for 
some time. — W. Machin, 35, William 
Street, Globe Fields, Mile End, London ;

An Enquiry, — Could any of your 
readers inform me how to find out if 
some eggs I have got of P. plumigera 
are good or not, as I am anxious to 
be certain ? — G. F. Mathews, Raleigh 
House, Barnstaple, 
Notes on Lepidopteea observed in 
THE Isle of Wight in 1857 and 
1858. 
Colias Edusa. This was abundant in 
1857, still more so in 1858, being first 
observed at Bembridge, Isle of Wight, 
June 13lh,and was thereafter seen almost 
constantly till October 30th. A female 
no bigger than a Polyoinmatus Corydon 
was seen but not captured. The insect 
was observed in every intermediate week, 
in good condition. 
Colias Hyale was not seen at all, or 
only once. 
Melitcca Cinxia. Notwithstanding the 
scores of this species taken from San- 
down by insatiable collectors, the number 
is undiminished. I possess larv®, now 
one-third grown, spun up in an oval 
patch in a dry spot. 
Sphinx Convolvuli occurred in August 
and September this year. 
Acherontia Atropos. Out of fifteen 
pupae I reared nine. The larv®, pup® 
and imago all made the same noise; it 
increased in depth of tone with each 
change. I fancy that it proceeds from 
the anterior spiracles. Respiration iu 
this insect is very visible. I have some-
