Fig. 4 The diploid groups, nucleoli of the growth-period, and late prophase- 
figures of the two species of Nezara. a, b, spermatogonial groups, hilaris;c, d, the 
same, viridula; e, f, ovarian groups, hilaris; g, h, the same, viridula; 7-1, chromatic 
nucleolus and plasmosome from the growth-period, in each ease from the same 
nucleolus in their relative position; m—p, corresponding views, viridula; g-t, the 
idiochromosome-tetrad (chromatic nucleolus) from prophase nucleoli, hilaris; 
u-x, corresponding views, viridula; y, late prophase nucleus, showing all the 
chromosomes, hilaris (combination figure from éwo sections); z, corresponding 
stage, viridula, three of the chromosomes from adjoining section at the right.
