The antennal ganglia (PL III., Fig. 2) exhibit a peculiar grouping of cells in small spherical masses, imbedded in a reti- cular substance. The infra-cesophageal ganglia have a similar structure, but each has a single large group of cells arranged in concentric layers (PL III., Fig. i, s) with smaller lateral groups (/) scattered through the reticular substance. The description of the splanchnic nervous system will be more conveniently given after I have described the remaining structures of the larva. 8. THE SENSORY ORGANS AND PERIPHERAL NERVE TERMINATIONS. With the exception of the sensory papillse, described on p. 36, the only special sensory structures I have been able^to. FIG. 12.—i. A section of the terminal joint of the Maxilla, showing the eye-like organs ; 2. A section of the eye-like organ (TV oil immersion lens) ; j. Endings of a nerve in the hypodermis, showing a peripheral ganglion ('a cotes de melon,' Viallanes). discover are the pair of eye-like organs at the extremity of each maxilla.
