The beetles are the highest Hexapoda T^•ith biting mouth parts. They are closest to the Orthoptera, as is shown by the structure of mouth parts and TOngs. The mandibles are strong; the (fig. 470) have lacinia and galea; the labium consists of a submentum (often called mentum), behind which the rudimentary mentum with its palpi, para-.
