Anaphase II—large cell (Feulgen). chromosomes lie in the approximate middle of the nuclear space instead of being carried to the periphery by the large autosomes (Fig. 48). The X and Y are at this time still in more or less intimate contact with each other and remain so until the first anaphase has begun. Another difference lies in the size relations between the X and the Y. In 3/V torhinus mclanolciicus the X is markedly larger than the Y, but this difference less pronounced in Mecistorhinus tripterus. In the latter also, as in most other pen- tatomids. the sex chromosomes become less sharply outlined in the second division and therefore it then becomes difficult at times to distinguish between then: 50). As a consequence, in about 25 per cent of fifty cells it is not possible to decide whether the autosome follows the X and there is at least the possibility that in such.
