ORDO I. 
INSECTA COLEOPTERA. 
This order is distinguished by the crustaceous elytra which cover 
the wings, and contains the following genera: 
GENUS I. SCAR ABÆUS, the Beetle, vide Tab. 1,2,3, and 4. 
Linn. Syst. Nat. page 361, 
The Scarabæus is known by the following characters ; — the 
antennae, or horns, terminate in a kind of club, divided longitudi- 
nally into an indefinite number of laminae, or plates. 
The second joint of the anterior or foremost pair of legs is fur- 
nished with spines, or teeth. 
There are three different sections, or families, of this genus, 
which are as follows: 
1. When the thorax is armed with horns. 
2. With the thorax unarmed, but having horns on their head. 
3. Those in which the head and thorax are plain, and without 
horns. 
Some individuals of each of these families are scutellati, or having 
the part called the escutcheon: others are exscutellati, or wanting it. 
Many of the larvæ, or caterpillars, of this genus, particularly those 
of the cockchaffer, conceal themselves in the earth, and live on the 
roots of plants, and in many instances are very destructive animals.
