The dotted lines indicate structures not in the median plane, a, Ceuthophilus, retracted; b, same, everted; c. Neduba; d, Gr\-llid, based on Crylhis; e, Acridid, based on Dissosleira and Melanoplus. For lettering, see page 71. On the roof of the penis there is a pair of small openings with ?chitinized margins, leading into narrow tubules (Fig. 25), which appear in sections to be partly glandular, but whose lining cuticle is minutely pubescent. In sections of specimens with everted parameres they are drawn backwards into the cavities of the latter. These structures have apparently no homologues in the other types of Orthoptera Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Entomological Society of America.
