THE ENTOMOLOGIST’S WEEKLY INTELLIGENCER. 
I would not advocate any one only 
directing his attention to the species of a 
single county, but wish that, whilst en- 
gaged in collecting British insects, parties 
would more particularly notice the habits, 
food, localities, &c., of those which occur 
in the county where they have the 
greatest opportunities for observation. 
I believe it is the duty of every ento- 
mologist — irrespective of the branch he 
studies — to do his best in adding in- 
formation concerning the distribution of 
species. With this view I propose that 
the entomologists of each county assist 
in the compilation of papers on the Lepi- 
doptera of the one in which they are 
resident ; and although there will be an 
inequality in the work which will thus 
be allotted to some, in proportion to that 
which will fall to others, — although in 
writing on the Lepidoptera of large 
counties you have greater obstacles to 
overcome than in writing on the species 
occurring in any of the smaller ones, — 
this should not prevent the plan being 
carried out, as a person compiling a list 
on the Lepidoptera of a small county 
may do so with but little assistance from 
those who have a knowledge of species 
taken in districts therein situated, and 
who are willing to add their information 
to this object. Parties must not forget 
that the larger the county the greater the 
possibility of omissions, which latter cir- 
cumstance should act as an inducement 
to the entomologists of large counties to 
give all the information they can to aid 
in their prevention. 
Where a county is so large and so pro- 
lific in its produce of species that a list 
is beyond the accomplishment of a few 
individuals, let the members of the 
Entomological Societies existing in that 
county unite in providing information 
connected with the localities they seve- 
rally explore, and let an union exist in 
furtherance of the work between those 
Societies. Let each Society have certain 
collecting districts allotted for the in- 
vestigation of its members, each of whom 
should commit to writing the results of 
his observation, and at the expiration of 
each month or season forward them to 
the Secretary of the Society to which he 
belongs ; from which latter source it 
must be sent to the Society that has 
undertaken the principal management. 
In Yorkshire I should recommend a 
division of the work into three parts ; 
one to embrace the species of the North, 
and the others those of the East and 
West Ridings, the most central Society 
in each being selected as the one to 
which the others in that Riding would 
send their information ; and after each 
of the three have completed their re- 
spective duties one of them must be 
chosen to arrange the whole into one 
work. The parts might also be divided 
into sections, treating on the localities 
near each large town, charts of such col- 
lecting-grounds being drawn out and in- 
cluded in the work, places productive of 
insect-life in each chart being numbered, 
and the numbers to be referred to in the 
notes of species occurring there. This
