Extract

In the second paper of this series I have selected for discussion the nymphal stages of three species. The first of these is Paurocephala fremontiae F. D. Klyver, the adults of which are described in the preceding paper. The other species considered are Psylla pyricola Förster and P. mali Schdbg., both of which are of special interest because of their economic importance. The nymphal stages of neither species have been adequately figured nor described in detail.
