THE ENTOMOLOGIST. 1138 
Improved Cyanide Bottle—Wrap a piece of cyanide, 
about half an inch square, in blotting-paper, folded two or 
three times; tie it round with cotton, and fasten it at the 
bottom of a wide-mouthed bottle with sealing-wax; then 
warm the bottle gradually over a lamp till the wax melts, and 
then cork it up. This has answered with me much better 
than the usual way of covering up with plaster; it also has 
the advantage of taking only a few minutes to make.—John 
B. Bridgman; St. Giles North, Norwich, March 29, 1875. 
Correction of an Error.—I regret to observe than an error 
has crept into my communication, published in the last 
number of the ‘ Entomologist. At page 82, line 6, 
“ Nephopteryx angustella” is printed for ‘ Qicophora 
augustella.” Your kindly noticing this will, I trust, prevent 
entomologists searching the trunks of horsechestnut-trees, at 
Hampstead, for Nephopteryx angustella, which only occurs 
among spindle.—Wm. Machin ; 22, Argyle Road, Carlton 
Square, E., April 20, 1875. 
Erratum.—iIn Mr. Talbot’s note (Entom. viii. 89), for 
“ Gelechia cinerella” ead “ Grapholitha cinerana.”

N. R. M—Larve Feeding on Turnip-seed.—I should be 
glad to learn something of the enclosed larve, which I found 
in February feeding on turnip-seed. I have occasionally 
found them before, but not in such great numbers. In about 
one pint of seed there must have been more than two 
hundred Jarve. I should also like to know if they are 
destructive to wood. 
[The larvz are evidently those of a Micro-Lepidopteron,— 
white, soft, and enclosed in loose cocoons, in which they are 
feeding. ‘The seeds are mostly attached to the outside of 
these cocoons, but some are also in the inside, which is 
somewhat more finished, and is very evidently a dwelling- 
place into which the larva can retreat at pleasure after its 
foraging excursions. The cocoons vary greatly in size, some 
being scarcely half an inch in length, others measuring two 
inches in length: they are very flimsy structures, and collapse 
directly the larva is removed. Owing to the outside being
