GENUS IL LUCANUS, the Stag Beetle. Tab. 5. 
Linn . Syst. Nat . page 559. 
The antennæ terminate in a sort of club, but compressed on one 
side ; this part is again divided into laminae, like the teeth of a comb. 
The maxillae, or jaws, are strong, projected, and armed with 
teeth. 
The larvae of this genus are generally found in decayed wood, 
and are in figure like those of the foregoing genus. 
GENUS III. DERMESTES. Tab. 6. 
Linn. Syst. Nat. page 561. 
The antennae of the Dermestides are formed club-wise, perfo- 
bated, and with an oval head, which is divided into different ho- 
rizontal leaves. These appear to be united by a thin stalk, placed 
through their centre, having three joints or articulations of a larger 
size than the others. 
The thorax is convex, and slightly margined. 
The head bent in, and concealed under the thorax. 
The Dermestides, whether as a perfect insect, or in the larva or 
maggot state, feed on every species of dead animals ; and indeed 
almost every kind of animal or vegetable substance, either in a 
recent or preserved state ; consequently are terrible enemies in the 
cabinets of naturalists ; and scarcely any method, or preparation, 
has yet been contrived effectually to destroy them.
