The nyniphal type In the prothoracic gland of the nymph and of the freshly emerged adult the cells are arranged in densely packed layers around the longitudinal axis of the tissue band. The center is occupied by a trachea, a nerve, and several parallel fibers of striated muscle all of which extend throughout the length of the organ (Figs. 3, 4). The nerve is evidently derived from the prothoracic ganglion, since no other nervous NERVE 8ffj •'.^J^. TRACHEA FIGURE 3.

The central nerve, in addition to innervating the musculature of the organ, probably also supplies the glandular tissue; the delicate branches of the nerve could be traced only for short distances in methylene blue preparations. Due to the contraction of the axial muscle the glandular tissue in fresh and in fixed preparations is more or.
