into alcohol, and by making artificial heads and bodies out 
of cork, and then painting them and fastening the wings to 
them with gum-arabic. 
In order, therefore, to prevent your cases of insects from 
being destroyed by this Cabinet Beetle, it is necessary to 
have the lining of the boxes, whether it be of cork or wax, 
well impregnated with spirits of turpentine, and, besides 
this, it will be well to fasten in each corner of the box a 
pin with a small piece of sponge attached to it, which may 
be saturated from time to time with the same fluid, or with 
spirits of camphor. The latter, however, can not be used 
in cases which contain butterflies, as the evaporation of 
camphor will make their colors fade. The cases them- 
selves, as a matter of course, should be made as tight as 
possible, in order to prevent the entrance of any living in- 
sect. 
The larva of the Cabinet Beetle is two lines in length, 
and has on each side of the body little bundles of reddish- 
brown hairs, which, when disturbed, it erects in the same 
manner as the Porcupine does its quills. These larve are 
sometimes seen upon our walls looking out for dead insects. 
The Carrion Beerues (Si/pha) have a broad body, with 
a shield-like thorax, upon which is a declining head with 
strong jaws, and with antennz terminating in a knob. A 
great number of species are found every where in North 
America, among which are, for instance, the 
Silpha marginalis, 
“¢  inequalis, 
‘¢ Surinamensis, 
‘¢ Americana, etc. ; 
but as the habits and character of one species are identical 
with all the others, the representation and description of 
one will serve for all the rest. 
The CrusapER Carrion BEETLE (Si/pha Americana) is 
more than half an inch long, has a black head, yellow tho-
