EXCHANGE. 
Hypogymna Dispar. — Having a num- 
ber of the larvse of this insect to dispose 
of, any persons wishing to avail them- 
selves of the opportunity of possessing 
this species may have it by writing first 
and stating what they can give in ex- 
change, either in ova, larvae or imago ; 
and, to disappoint Young Barnes, no 
letters will be attended to that come to 
hand before Wednesday, the 8th of June. 
Those who do not receive answers within 
fourteen days will understand they are 
not accepted. — F. Bradley, Thompsons

KNOTTY POINTS. 
To the Editor of the ‘ Intelligencer.' 
Sir, — I am very glad to see that you 
have yourself settled, in a very masterly 
way, a knotty point of great importance. 
There has, for some time past, been a 
continual and increasing demand for a 
railroad to the Temple of Science ; every 
scholar is ambitious of mouuting a pe- 
destal at once in that splendid structure, 
without having to toil uphill, with great 
labour and perseverance, and thus endea- 
vour to prove himself worthy of such a 
position. You, sir, have hit the nail in 
the right place when you say, “ many 
persons labour under the delusion that 
everything should be so plainly written 
that its meaning should be apparent 
ivithout the slightest study ; nine times 
out of ten, if an author is not understood 
the fault lies with the reader.” Capital ! 
Young gentlemen, learn by heart the 
whole paragraph from which I have 
quoted, copy it in a fair round hand, and 
stick it up in your study. Sir, it is quite 
obvious to me that young naturalists 
must study carefully not only the pages 
of entomologists, but they must also in- 
vestigate the habits of insects in the 
woods and fields. 
It gives me great pleasure to see occa- 
sionally in your pages announcements of 
captures of rarities, and of the intention 
of the captor to distribute his duplicates. 
What is a duplicate? I dropped into a 
sale-room the other day, and saw ninety- 
six specimens of one unfortunate species 
of bee in a box which had the following 
memorandum written inside the lid : — 
“This species is very rare in the West of 
England, although occasionally plentiful 
in this neighbourhood.” How many of 
those were duplicates ? What a pleasure 
it must be to capture ten specimens of a 
rare insect, and to feel that it is in your 
power to enrich nine other collections 
with the same rarity. 
Perhaps you can settle another knotty 
point for me, When will Mr. Water- 
house finish his Catalogue of Beetles? 
A satisfactory answer to this will greatly 
oblige 
Yours faithfully,

Apiarian Society. — The first meeting 
of this newly-formed Society took place 
on the 23rd of May, at the rooms of the 
Entomological Society, Bedford Row; 
the Rev. S. Wand, of Brettenden, Essex, 
in the chair. The Report stated that an 
experimental Apiary had been established 
and placed under the care of the Secre- 
tary, at Muswell Hill, to which the public 
were admitted by members’ orders. Mr. 
Shirley Hibberd stated that numerous 
donations had been received for the 
library, and that it was the intention of 
the Committee to institute lectures on 
improved systems of bee-keeping, and 
also to offer prizes to cottagers for the 
best examples of bee management. Mr. 
Tegetmeier described an entirely novel 
method of bee-keeping adopted in
