Antennae
The antennae are jointed appendages inserted in front of or more rarely between the eyes, usually under the side margin of the front. They vary in shape and in the number of joints (from two to twenty five or twenty seven), the usual number being eleven.The joints nearer the head are usually of denser consistence than the outer ones and less pubescent. The forms of the antennae may be reduced to the following types:_
Filiform, having joints of uniform thickness, or nearly so.
Setiform, having joints more and more slender to tips.
Serrate, having joints triangular, arranged like saw teeth.
Clavate, having the apical joints much more elongate than the others.
Capitate, having the terminal joint grealtly enlarged so as to form a knot.
Moniliform, having the joints globular.
Pectinate, each joint having a long process on one side, like the teeth of a comb.
Pinnate, having processes on both sides, feather-like.
