The suctorial action of the pharynx of the larva of CEstrus was first pointed out by Scheiber [21]. The upper and back part of the pharyngeal sinus of the young larva lodges the antennal disc sac. In the adult larva this is placed behind the cephalo- pharynx, but it sends a pair of processes into the pharyngeal sinus, between the cornua and the inferior processes, in which the imaginal rudiments of the fulcrum of the fly are 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 Lowne, Benjamin Thompson, 1839-.
