PRESERVATION OF INSECTS. 
I have long been of opinion that 
camphor is of very little use, and in 
ome cases even worse than useless, 
aving found that it has a tendency 
to produce grease, in large moths 
especially ; and I am glad to see that 
this opinion is confirmed by so emi- 
nent an entomologist as Mr. Henry 
Doubleday. 
Some lepidopterous insects are 
much more liable to become greasy 
than others, especially the puss 
moth ( Ceram Yinula ), &c., and the 
females of the painted lady but- 
terfly ( Cynthia C ardui). And here, 
perhaps, I may be allowed to state 
what I have found the most effec- 
tual way of cleaning such speci- 
mens. With a camel’s hair brush 
I saturate them, wings and all, above 
and below, with the best spirits of 
turpentine, then place them on the 
setting-cork, with finely-powdered 
or scraped French chalk beneath, 
and subsequently cover therewith 
the whole of the upper surface of the 
insect. In two or three days the 
chalk will absorb the whole of the 
the turpentine and the grease there- 
with, and the insect being removed 
from the cork, the chalk may be 
blown or brushed off, and in most 
cases the insect will be found quite 
clean, and the colours and markings 
not injured. The turpentine will 
also render the specimen less likely 
to be attacked by mites. 
A very effectual specific for mites 
is that recommended by Mr. Stain- 
ton, viz.: — 
Equal parts of spirit of wine, 
„ oil of aniseed, and 
„ oil of thyme.
