tlie first case pass over the tendons of the 

 mandibles, and in the second proceed contigu- 

 ously to the great flexors of the mandibles, to 

 the root of the antennae, immediately beneath 

 the membrane connecting them to the clypeus, 

 but without sending off branches. They run 

 from the base of the antennae to the apexes, 

 giving off on all sides delicate auxiliary branches 

 to the muscles. (Burmeister.) (L.) 



Nervi labii. — The labial nerves ; these nerves 

 come, when separated from those of the 

 maxillae, from the centre of the anterior margins 

 of the cerebellum, and run direct to the labium, 

 and here divide into several — generally two — 

 main branches, the inner ones going to the 

 tongue, and the outer ones to the labial palpi. 

 (Burmeister.) (L.) 



Nervi mandibularum. — The mandibular^ nerves. 

 They pass out of the anterior portion of the 

 cerebellum ; they give off several delicate 

 auxiliary branches to the flexors and extendors 

 of the mandibles, and lastly, accompanied by 

 branches of the trachea, pass into the cavity of 

 the manlibles, (Burmeister.) (L.) 



Nervi maxillarum.— The maxillary nerves. They 

 sometimes originate in front, and sometimes 

 behind the nerves of the mandibles, from the 

 cerebellum, and run closely to them, passing 

 between the muscles to the maxillae. (Bur- 

 meister.) (L.)
