- The Rhynchophora are a group of beetles easily recognized by the elongation of the head into a beak or snout, which carries the feelers at its sides and the jaws at its tip. The third tarsal segment is broad and bi-lobed, and the fourth is so small that the feet seem to be only four-segmented.

The extreme of this " division of labour " is seen, in those insects whose jaws are vestigial in the winged state, when, the need for feeding all behind them, they have but to pair, to lay eggs and to die.
The characters of the wings are doubtless important as indications of relationship, but the nature of the jaws and the course of the life-history must be considered of greater value.
Piercing jaws modified and reduced, a tubular, protrusible suckingtrunk being developed; mouth with hooks.
To the Permian period belongs a remarkable genus Eugereon, that combines hemipteroid jaws with orthopteroid wing-neuration.
But the vestigial jaws, numerous Malpighian tubes, and specialized wings of may-flies forbid us to consider the order as on the whole primitive.
Further examination of the enormous collections gathered by the author, and preserved in the Museum of Yale University at New Haven, Connecticut, showed him that this last bird, and another to which he gave the name of Apatornis, had possessed welldeveloped teeth implanted in sockets in both jaws, and induced him to establish (v.

Teeth and jaws probably referable to the Condylarthra have been obtained in European early Tertiary formations.
Again, the adult Pentastomum shows no trace of appendages, unless the two pairs of chitinous hooks are to be regarded as the vestiges of jaws or ambulatory limbs.
