their several circles; this is called the Quinary system. There has, 
also been an attempt made, to arrange them according to their food. 
M. Clairville adopted the method of uniting the principles of several 
of the former systems ; this is called the Eclectic, ov Modern system: 
this is followed by Latreille, Dr. Leach, and Mr. Stephens; the last 
of which I intend to explain, not because I conceive it superior to 
every other system, but because I am the most acquainted with it. 
The first division, or sub-class, he makes, is called Blandibulata, in- 
cluding all insects with mandibles, or teeth ; this division has seven 
orders. 
Order I. — COLEOPTERA, (from /co^eo*, a sheath, awA pteron, 
a wing,) because they have Avings in elytra, wing-cases, or sheaths. 
This is again divided into sections, and sub-sections. 
Section 1. — Adephaga, • Voracious. Sub-section 1. — Geodo- 
PHAGA, Ground Beetles, or such as feed on land. These sub-sections 
are again divided into families ; the first of Avhich is, Cicindelidce, or 
such as resemble, in general structure or habit, the Scale-Beetle, or 
Sparkler, Cicindela; the only genus at present this family contains. 
The most remarkable species is the C. Campestris, one of the most 
beautiful Beetles this country affords: the whole upper part of the 
body is green, tinged with blue ; underneath is a mixture of yellow, 
red, or copper, and the e/j/^ra, or wing-cases, are delicately marked 
with small white spots ; it is to be found in sandy soil, on warm sun- 
ny banks ; the lan^a, or grub, is long, cylindrical, soft, whitish, and 
furnished with brown scales, a square head, and six or eight eyes ; 
it has strong jaws, and is exceedingly rapaci&us, being a cannibal. 
M. Desmarest informs us, that with great labour the animal digs in 
the earth, to the depth of 1 8 inches, to form a trap to catch its prey ; 
to effect this, it carries out small masses of earth on its large concave 
head, and having often occasion to rest in ascending, it fixes itself to 
the side of its burrow, by two hooks, fixed on two fleshy tubercles 
on the eighth joint of its body ; having arrived at the top of its hole, 
it casts offits burden. While these insects lie in wait for their prey, 
the head, and the first segment of the body, is supposed to stop up 
the mouth of the burrow, so as to form a level with the surround- 
ing soil, and insects walking carelessly, within reach, are seized and 
devoured without mercy, in a moment. When it is about to undergo 
its transformation into a pupa state, it carefully closes up the mouth 
of its den, and retires to the bottom.
