MOTHS AND BUTTERFLIES. 
which I have used with success is to snip off the abdomen of such 
an insect, cut it open on the under side, remove the contents and 
soak it in gasolene for twenty-four hours, after which it can be 
stuffed and replaced in its former position with shellac. This pro¬ 
cess, of course, does away with all liability of the insect becoming- 
greasy. 
To restore the beauty of greasy specimens, place them in gasolene 
in a shallow, covered pan, for twenty-four hours or longer, when they 
will come out bright and clean. Downy or hairy specimens may need 
a little blowing to restore their fluffy appearance. 
The fumes of bisulphide of carbon will kill insect pests which 
may have found their way among unmounted specimens. Pour an 
ounce or two into a dish placed in the cabinet and close it up tight 
for forty-eight hours. Care should be exercised in its use, as it is 
very volatile and explosive.
