THE ENTOMOLOGISTS WEEKLY INTELLIGENCER. 
and attended to in order to prevent its 
destruction, for this constant demand 
upon one’s attention and time must be a 
serious interruption to one’s other pur- 
suits. I myself would willingly spend 
some additional time and labour upon 
my acquisitions if by thus doing I could 
free myself from future trouble, and could 
put them by as I would a collection of 
eggs, &c., at liberty to turn my attention 
at once to other things. I have been 
thinking, then, that a strong solu- 
tion of corrosive sublimate in sprits 
of wine, if applied to the bodies of 
insects, might possibly preserve them 
perpetually from vermin, and that with- 
out any injury to the specimens, and I 
want, from some competent authority, 
answers to the following: — 1st. Is there 
any thing which would be preferable to 
the corrosive sublimate for the above 
purpose, and if there is not, would that, 
properly used, make it impossible for the 
insects, to which it was applied, to be in- 
jured at any time by vermin? 2nd. 
Would the application of this damage 
the specimens in any way, either at once 
or in course of time? 3rd. What is the 
best mode of application, if it be decided 
to use it ; would it be sufficient to apply 
the solution with a brush to the bodies of 
the insects, or should they be wholly, or 
in part, immersed in it: might not beetles 
be immersed, and their outsides washed, 
if necessary, afterwards? — John Lin- 
nell, Jun., Red Hill; April 28, 1857. 
[Will some of our correspondents give us 
their experience on this subject.] 
Explanation of Scientific Terms. — 
In the current number of the ‘ Ma- 
nual’ you give excellent advice — “ to call 
insects by names by which other people 
will know them and at page 314, re- 
ferring to the Family Catocalidce, an ex- 
planation occurs thus: “the name of the 
genus signifies ‘beautiful beneath.’” To 
those who have “ little Latin and less 
Greek,” a systematic explanation of this 
character would facilitate the adoption 
of your advice by novices. Paxton and 
Lindley’s ‘ Botanical Dictionary ’ is an 
example of this kind. Can any thing be 
done in this direction for Entomology ? —

Lane, Deptford ; April 13, 1857. 
Change of Address. — I have lately 
changed my place of residence to Spring 
View, Liscard, Lancashire. — Nicholas 
Cooke, late of Everton , Liverpool; April 
13, 1857. 
COLEOPTEEA. 
In our last notice we strongly* recom- 
mended those Coleopterists to whom 
“ the ways and means” are likely to be 
forthcoming, not to allow the entire 
campaign of 1857 to pass away without 
devoting at least a portion of their time 
to travelling, in order that, by the close 
investigation of some particular spot as 
yet but imperfectly explored, our general 
knowledge of the topographical distribu- 
tion of species may be gradually matured, 
and that, too, simultaneously with the 
accumulation of their season’s material. 
It is only, indeed, by realising this two- 
fold object of their mission, that a vast 
proportion of our collectors can be in- 
duced to turn their labours to good 
account ; for to content themselves with 
the mere bringing together of specimens 
(apart from the observation of collateral 
facts) is not sufficient, but to work out 
the statistics of any given locality, iu 
connection with its Fauna, not only adds 
to our immediate stores, but confers, at 
the same time, a solid boon upon 
Science. If a tithe of our beetle-hunters 
would bear this steadily in mind, how 
much vaster would be the increase of 
knowledge at the end of every year than 
it is! Let us hope, however, that a 
brighter era is dawning upon the ento- 
mological world, and that the real im- 
portance of insect-geography, as regulated
