Thecoxopodites of the ninth segment, on the other hand, are evidentlycontained in the posterolateral parts of the apparent ninth sternumof the very young nymph (A, IXS) ; later they appear as distinctmembranous lateral areas (C, IXCxpd) from which the third valvulae(jF/) project as direct continuations, and from which the small sec-ond valvulae {2VI) arise medially as endite lobes. The coxopoditeareas remain membranous in the adult. The true sternal region of.
