Abstract
A description is given of those nerves which arise from the mesothoracic ganglion of Locusta migratoria migratorioides R. & F. There are six pairs of nerves, of which the sixth and most posterior are referred to as recurrent nerves since they join the first nerve of the ganglion in the metathorax. The median nerve is also described. The posterior median nerve of the prothoracic ganglion is noted as its branches make a connection with the branches of the first mesothoracic nerve. Wherever possible an attempt has been made to relate the observations to those of some other authors.
