In those of the second, the elytra are serrated, or armed with
short spines, near their extremity.
In the third, they are whole or entire.
The late celebrated entomologist Mr. Thomas Yeates, of whose
critical knowledge in, and just definition of the Linnaean principles,
the Author has greatly availed himself, says, “ that very
“ few insects of this genus in his time were found in Europe, and
“ not a single specimen had been taken in England.” Collectors
have since, however, been more fortunate, and four different
species are figured, all of them for a certainty English.
We are wholly unacquainted with their larvae and transformations.

The antennae of this genus are either setaceous, or enlarged in
size towards the point, with aperfoliated capitulum, or knob.
The hind feet are hairy, which assist them in swimming, and
are also furnished with claws.
The Dytisci form two families ; the first are those with perfo-
liated antennae; second, those whose antennae are setaceous.
The under side of the fore feet of the male is hemispherical;;
the elytra of the female are mostly furrowed. The male is something
like the Dermestides, and the female resembles the Carabi:
but in general the sexes are very difficult to be distinguished.
There are many species of this genu,s in stagnate waters, which
they quit in the evening; and fly about. Their common name is
Water Beetles.
Their larvae are frequently found in ditches.

The antennae of this genus are setaceous., i;
In form, the thorax resembles a heart, with the point cut off,
and is margined; as are also their elytra.
There are two families; the larger Carabi, and the smaller ones;
both of which subsist on larvae, or weaker insects-
The larvae live in the ground, or decayed wood, where they undergo
their transformations, and subsist oil small insects,

Their antennae are moniliform, resembling a string of beads, the
last articulation being the roundest.
The thorax is of a convex form, a little depressed and margined.
The head is projected, or stretched forward.
The Tenebriones are formed into two families; the first being'
those whose elytra are united, or without a longitudinal suture,,
wanting wings: and the second, such as are furnished with wings.
Their larvae are mostly found under pieces of wood, or any other
object lying on the ground, in fields and gardens: the insects are
common in houses, and have a very foetid smell, whence they are
termed Stinking Beetles;'
