sternum, situated in front of the coxae and usually extending between them. The anterior lateral piece is the episternum, the posterior, the epimeron.
The cavities in which are inserted the anterior legs are called the anterior coxal cavities. They are either entire when they are inclosed behind the junction of the prosternum and the epimera, or open when a space is left protected only by a membrane; they are separate when a space is left between them, or confluent when there is no visible space.
The second segment is the mesothorax. It is very closely united to the third segment or metathorax, which in turn is closely connected with the abdomen.
These two segments support on the ventral surface the middle and hind legs and at the sides of the dorsal surface, the elytra and wings .
The dorsal surface of these segments is covered by the elytra, hence they are invisible; they are called mesonotum and metanotum and
