Color.—-Dull white or grayish, often with a yellowish tinge, very thickly mottled on dorsal surface with confluent blotches and dots of dark brown color; A'entral surface grayish, often ^nth tinge of yellow. Ocelli. — On each side of head there are commonly 18 to 28 ocelli, arranged in two irregular groups (PI. 22, fig. 157). On each antero-lateral margin is a single row of 4 to 6 rather large ocelli, which continues ]iosteri- orly into an irregular, marginal group of 8 to 12 smaller eyes; while an irregular cluster of 7 to 10 small ocelli lie just in front of brain and deep in the tissues of the head. Proboscis.—Provided with usually 17 nerves. Central stylet very slen- der, of about the same length as basis, which is very broad and flattened pos- teriorly (PI. 22, fig. 158; Text-fig. 50). Submnscidar glands enormously developed (Text-fig. 3), extend- ing nearly the whole length of esophageal region. Intestinal caeca extend forward well toward the brain. Nephridia situated in anterior portion of esophageal region; there is a single pair of efferent ducts, opening ventro-laterally. Cerebral sense organs well developed, situated in front of brain. Reproductive organs.— Sexual products mature in July; they. Fig. 50. — Amyhiporus nebulosus.
