Figure 19. Medial view of the left nietathoracie leg and trocdiantin. The mesothoracic coxae lie closer to the body than do those of the prothorax. They project posteromedian}^, nearly touching each other at the midline (Fig. 2). Distally they are nearly spherical in shape; proximally the side which contacts the coxal process is considerably longer than the opposite side. The hasi- costal suture is not as marked as that of the prothorax. It seems to disappear medially, while laterally it separates off the very narrow anterior and posterior hasicoxites. The joints between the various segments of the leg are essen- tially the same as those of the prothoracic leg. Also the tendons within the segments occupy the same positions as those of the.
