and Hupecilie. Mr. Meek has introduced enamelled pins 
impervious to verdigris, but they have hardly been in use long 
enough for théir true value to be estimated. 
There are several methods of killing Tortrices, some of which 
are preferable to others, for they do not stiffen the specimens 
after death: of these liquid ammonia is most to be recommended ; 
by this agent several insects can be killed at the same time by a 
few drops of the fluid. The boxes containing the specimens to 
be killed, having been opened a little on one side to admit the 
fumes, should be placed in a large basin or box (a high hat is 
often handy) with a few drops of the liquid on a sponge or piece 
of wadding, and the whole covered over with a towel or cloth. In 
little over half an hour the insects will be ready for setting. The 
great drawback, however, to the use of ammonia, is that the 
fumes hang about the boxes so that they cannot be used for other 
captures immediately afterwards, but require to be left open for 
an hour or two to air. Chloroform, on the other hand, is free 
from this objection, but is very apt, unless with careful handling, 
to render the specimens rigid and difficult to set. I have, however, 
used it for several years, and consider it preferable to all other 
poisons. A strip of blotting-paper dipped in the chloroform is 
inserted in the pill-box containing the insect to be killed, which 
in a few seconds may be set, and the blotting-paper is free for 
another victim; and so on, taking care never to kill more than 
one or two specimens at a time, and to set each specimen as soon 
after death as possible, and before rigor mortis has had time to - 
set in. 
From these few hints, which I trust may be of service to those 
about to commence the study of the Tortrices, I will next month 
pass on to the list of the species occurring in the south- eastern 
counties.
