The accessions catalogue has been arranged in a way that, so far as 
known to me, is largely original. The left-hand page is divided into 
seven columns, each of which is filled out after the following manner: 
The first, or the one nearest to the outer margin, is used to indicate the 
number of the bulletin in which the information relating to the species 
has been published; the second space contains the accessions catalogue 
number; the third space indicates the number and page of the journal 
containing the further records relating to the species; fourth, the name 
of the species; fifth, the locality from which it came; sixth, date of 
collection or of sending, if it has been sent us by a correspondent; 
seventh, name of collector or sender. This occupies the entire left-hand 
page, while the right-hand page is divided into two spaces only. The 
first, or the one on the left, is quite narrow and contains the number of 
the letter file in which the letter accompanying the specimens, if sent 
by a correspondent, is filed, the remaining space being devoted to 
remarks, which include any short item that can be expressed in a very 
few words. All additional information ontside of this is taken to the 
journal, and its position in the journal is indicated in the third space 
from the margin on the left-hand page, as previously indicated. When 
the breeding notes are finished and revised they are transferred to the 
journal, as every one knows that original notes, in order to be of value, 
must contain a great deal that it is not usually necessary to use in print. 
In other words, the journal is supposed to contain the essential facts 
obtained regarding the species, together with such details as seem of 
sufficient importance to include. The journal is arranged in this manner: 
Starting at the top of the page, first will be given the accessions cata- 
logue number; following it on the upper line the food plant or other 
host if such is known, followed by the name of the species if we have 
it, and if parasitic the fact is also indicated. Below this is given the 
date of observation, and following this the note itself. It will be seen 
that by this means we are able not only to gather together all of the 
material relative to a single species, but also our own notes and records, 
even to the original slips that we have removed from the cages or 
jars. Besides this we can at once find not only the original letters from 
the parties sending us the material, but any replies we have previously 
made thereto. As I stated before this system requires considerable 
bookkeeping; but when we come to use our notes and correspondence, 
as well as to refer to the material, we find that it is but a very simple 
task to get it all together, and we here save much more time than we 
have expended in keeping our records. 
It perhaps might be well to point out some of the defects in this 
system, as well as some features of the problem upon which we are very 
anxious to get additional ideas from other workers. As I stated before 
we sometimes find our system of numbering rather cumbersome. For 
instance, we collect a large amount of fallen leaves about a vineyard. 
These are collected in midwinter, brought into the insectary and placed
