In this report, there are represented the events in the generative nuclei of the termite Nasutitermes sp., beginning with the youngest oogonium in the germarium up to the mature, but not yet fecundated egg in the oviduct, considerating Syntermes dirus like comparative species. The principal results are the following; 1. The germarium and the terminal filament are separated from each other by a wall of conjunctive tissue, sowing that the central series of nuclei of th filament has nothing to do with the generative nuclei of the germarium. 2. The growing to the oogonia, oozytes, nuclei and nucleoli is represented in figure 32. In the nuclei of the oogonia occur the typical modification of the chromatine of a meiotic division up to the state of tetrades. During these events, the nucleolus suffers only little important modifications; it remains present during all the occurrences of prophase and continuates its growing in the same proportion like the nucleous during the dissolution of the tetrades (tab. 2). 4. The nucleous is not dissolved on the end of the production of yolk, to be newly reformed, later on, in a peripherical situatio, as described by other authors; in all stages up to the mature egg in the oviduct it may be observed with all its characteristics. 5. It is supposed that the preasynaptic occurrences in the nucleolus and its premanence during synapsis and postsynapsis suppress the expected formation of a meiotic fuse.
