408 SYSTEM OF INSECTS. 
There are two tribes in the animal kingdom that seem 
placed in contrast to each other, both by their habits and 
by their structure. One of these is carnivorous, living 
by rapine and bloodshed, and cannot be rendered sub- 
servient to our domestic purposes ;. while the other is 
herbivorous or granivorous, is quiet in its habits, and 
easily domesticated. Amongst insects we find the re- 
presentatives of both: those of the first tribe are distin- 
guished by their predaceous habits, by the open attacks, 
or by the various snares and artifices which they employ 
to entrap and destroy other insects. They may usually be 
known by their powerful jaws or instruments of suction ; 
by their prominent or ferocious eyes; by the swiftness 
of their motions, either on the earth, in the air, or in the 
water; by their fraud and artifice in lying in wait for 
their prey. Amongst the Coleoptera, the Predaceous 
beetles,—including the Linnean genera Cicindela, Cara- 
bus, Dytiscus, and Gyrinus,—are of this description; and 
they symbolize those higher animals that by open vio- 
lence attack and devour their prey:—for instance, the 
sharks, pikes, &c., amongst the fishes; the eagles, hawks, 
&c., amongst the birds; and the whole feline genus 
amongst the beasts. Similar characters give a similar 
relation of analogy to the Mantide and Libellulina 
amongst the Orthoptera and Neuroptera. ‘The whole 
family of Arachne, the larvee of the Myrmeleonina, &c., 
portray those animals that to ferocity add cunning and 
stratagem, or suck the blood of their victims. The my- 
riapods symbolize in a striking manner the Ophidian 
reptiles. Look at an Judus, and both in its motions and 
form you will acknowledge that it represents a living ser- 
pent; next turn your eyes to a centipede or Scolopendra,
