PI. IX. N. B. In Plates IX. XIV., which explain the composition of the 

 thorax in the different orders, for the sake of distinction the prothorax is

 the mesosternum, F the metanotum, G the metasternum, H the parapleura, 

 I the pleura, K the coxa? (generally of the posterior legs). All the figures are
