MR. NEWPORT ON THE SPHINX LIGUSTRI. 
filament to the posterior surface of the cerebral lobes, near where they are 
united, d. Nerves to the antennse. e. The ganglion formed above the 
mouth by two nerves from the lower part of the front of the lobes, and which 
gives its nerve e along the oesophagus to the stomach, and which has been 
called the recurrent nerve. 
a. Anterior lateral ganglia, b. The mandibular nerves which are now 
given to the tongue, c. Lateral nerves from the first ganglion, given to the 
salivary organs or silk-bags of the larva, d , d. Nerves from the front 
of the first ganglion, given to the inferior surface of the cavity of the 
mouth, into the substance of which they enter. They seem to be those 
which, in the larva, supplied the spinneret or excretory of the silk-bags. 
e. The nerve to the stomach, f. The nervous circle arising from the part 
of the lobes near the recurrent nerves, and, as in the previous state of the 
insect, encircling the pharyngeal portion of the oesophagus, at the hinder 
part of the mouth, g, g. Small nerves from the base of the antennae passing 
downwards and uniting with a branch from the trigeminal or true mandi¬ 
bular nerves, and also with the nerve from the anterior lateral ganglia. 
h. Anterior plexus of transverse nerves from the second ganglion, i. A nerve 
connecting the plexus with the anterior lateral ganglia, k, k. Nerves con¬ 
necting the plexus with the first pair from the second ganglion. /, m. Nerves 
which anastomose and supply the muscles of the collar, n. Nerves to the 
first pair of legs. o. Branches of tracheal vessels ramifying over the surface 
and entering into the substance of the nerves and ganglia.
