Pgralis Glaucinalis. — In this week’s 
‘ Intelligencer,’ Mr. Tearle says the larvae 
feed in the raspberry-stems, eating the 
pith. With us they adopt a different 
system, more in accordance with the 
habits of the group. During the last 
few years the moths have commonly been 
beaten out of the thatch of an old hut 
naar Carrington Moss: the thatch is 
composed of heather and straw, both far 
decayed. In this the larvae feed ; when 
full fed some descend to the turf below, 
others remaiu in the thatch. They spiu 
a beautiful white silk cocoon, open at the 
head part, in form a compressed oval. 
The moths vary exceedingly in colour. —

Unknown Larvce, — I have the following

happy to send specimens for description 
when full grown : — 
Aciilalia rustica. On elm. 
... imitaria. On Galium. 
... inornata. On willow. 
Larentia Miaria. On Galium.

The Glow-worm (Lampyris Noctiluca). 
— When I was at Llandudno, this sum- 
liner, I bad frequent opportunities of ob- 
serving the glow-worm, and I have 
pleasure in sending you a few remarks 
for the information of those of your 
ireaders who may not be acquainted 
■ with this luminous insect. It is classed 
by Stephens, in his ‘Manual of British 
IBeetles,’ among the Malacodermata. 
IThe male is winged, the female wingless. 
Both sexes are furnished with light. In 
;the male the light is confined to two 
-small spots at the tip of the abdomen. 
IThis light is generally veiled ; but, in 
uhe summer, when his mate kindles her 
'.torch of love, the two luminous spots are 
listinclly visible. In colour and general 
aspect the male glow-worm bears some 
resemblance to the click-beetle [Agriotes 
linealus). The elytra are marked with 
three elevated lines, and the thorax is 
produced in front so as completely to 
conceal the head. The eyes are black, 
very large and prominent. The female, 
as I said, is perfectly wingless; and, 
were it not for the thorax that shields 
the head and the raised dorsal line, it 
would give the idea of an attenuated 
woodlouse. The beautiful phosphoric 
light proceeds from the under-sides of 
the last three rings of the abdomen, and 
is contained in two bags immediately 
beneath the rings. The creature has the 
power of varying at will the intensity and 
diffusion of its light. Glow-worms feed 
in the larva state on snails, pursuing 
them even into their shells, and ap- 
parently indifferent to the mucous secre- 
tion with which the snail clothes itself in 
its own defence. The larva is said to have 
also the luminous property in a slight 
degree. — Peter Inchbald, Storthes 
Hallf near Huddersfield ; August 18. 
EXCHANGE. 
Erehia Blandina. — I have a good 
number of this insect, and shall be very 
glad to exchange with any one who will 
send me a list of duplicates. — W. Lang, 
John Street, Hamilton, N.B. ; Aug. 26. 
Hydrcecia Petasitis . — Having had the 
luck to capture seventy or eighty speci- 
mens of this in.sect in pupa, I shall be 
glad to exchange with any one who will 
send me a list of duplicates. — Edwin 
Miller, 28, Buck Granges Road, Man- 
chester ; August 22. 
Overwhelmed with Applications . — My 
larvce and eggs are all gone. Time will 
not permit me to answer all the numerous 
letters ; therefore I hope all those not 
answered will excuse me, and take this 
as an answer. — VV. Winter, Aldeby, 
near Becclcs ; August 26.
