Whether this process (the "End- faden" of previous authors) extends to the distal end of the cap cells could not be determined; if so, it is much finer and more difficult to see distally than proximally. Eggers ('28) considered the scolopophorous organs of the Hydrocorisae to be "amphinematic," a term used for organs whose "Endfaden" extend all the way to the integument. Wotzel ('33), however, reported that the Hydrocorisae lack "Endfaden" and thus pos- sess "mononematic" scolopophorous organs. Larsen ('57), al- though unable to trace the "Endfaden" to the end of the cap cells in most of his preparations of Hydrocorisae, believed them to be present in all. Gray's ('60) study, unfortunately, offers no hints as to the nature of the "; At the base of the sensillum lies a large sensory cell (Figs. 6, 11, SC) with granular, lightly-staining cytoplasm and a round nucleus containing few chromatin granules. In the discolopodial organs the sensory cells of the two sensilla lie close together and are surrounded by supporting cells (Pig. 11, SUP) ("akzes- sorische Zellen" or "Hiillzellen" of previous authors). The. -SUP Fig. 11. Detail of the base of the left mesothoracic discolopodial organ. Frontal section through the body. Anterior region is shown at the bottom, posterior region at the top.
