insects have been pinned or gummed upon the paper points, and before 
the locality labels have been attached. We do not use the sheet cork 
quite full length, but probably extending beyond the block some 4 or 5 
inches, using the one-quarter-inch thickness of sheet cork. We are 
using the paper points, cut by a punch made for the purpose, but this 
works hardly satisfactorily, as the punch soon becomes dull and leaves 
the edges of the points more or less ragged. For mounting insects on 
these points we use ordinary glue, thinned to the proper consistency, 
and for holding this we use the common balsam bottle of the micros- 
copist, with glass dropper, fitting loosely in the neck of the bottle, with 
ground glass cap. This last contrivance was borrowed from Dr. Hop- 
kins, and we find that it works very nicely, indeed, as the ground-glass 
stopper prevents the glue from becoming too thick, while the dropper is 
very convenient for applying the glue to the tip of the paper points, 
although one needs to get a dropper with a very fine point. For local- 
ity and date labels we use neatly-printed squares, and for the printing 
we use the 6-point lining Gothic (No. 32) type, on a good quality of paper. 
With the insects reared, or collected, and carefully mounted, they 
are then ready to be recorded in the accessions catalogue, if indeed this 
has not already been done. It very frequently happens that a species 
has been given an accessions catalogue number, when it is in the pupa 
stage, or if we have secured parasites. In this case we use the same 
number for all stages of development, and for the parasites, although 
the latter when determined are given an independent number on the 
accessions catalogue with a reference to the original one. It may, per- 
haps, be stated here, that where breeding cages are used, all records 
are kept on a Sheet folded to go in a small, galvanized-iron case, and 
are thus protected from being wet or in any way injured, by a glass 
cover which slides into the case, over and in front of the notes. When 
these notes are completed the sheet is unfolded and filed away for future 
reference, in case we should find it advantageous to go back to the 
original notes. In using jelly cups, we do not-place the notes inside as 
these often offer altogether too inviting material for some insects to 
use in the construction of their cocoons; so these notes are kept always 
upon the outside, but when they are completed they, like the others, 
are filed away, so that they may be referred to in case it should become 
necessary or desirable to do so.
