Abstract
(1) In Mecostethus grossus chiasma-localisation affects the chromosomes to different degrees. One individual was found showing unusual variability in regard to chiasma frequency. (2) Metrioptera brachyptera (Tettigoniidae) shows chiasma-localisation, at any rate in the five larger bivalents. As in Mecostethus the different bivalents are unequally affected. (3) In both species the relation between chiasma-frequency and chromosome length is an indirect one, some of the smaller bivalents having a higher chiasma frequency than larger ones. (4) The causes of chiasma-loealisation are briefly discussed.
