Posterior field: of tegmina, = anal field; q.v.
Posterior intercalary: in Diptera, is one of the anal veins (Comst.).
Posterior lateral margins: in Orthoptera, extend from base of pronotum downward to the posterior angle of sides.
Posterior lobe: of the pronotum in Orthoptera, see lobe: in Diptera, that part of wing between axillary incision and base: = alar appendage (Loew). Posterior margin: = inner margin; q.v.
Posterior pereion: the meta-notum.
