(TnC) fused entirely with the sterna and epi- 



sterna in each segment. 

 aa, muscle arising from inner wall of mesothoracic pleurum

ff, so-called "wax shears" or "wax pincers." 



gg, transverse chitinous band of empodium (Emp), which

nn, "stomach-mouth" at summit of pro ventricular pro- 



jection within honey stomach (HS). 



oo, pores on lancets and shaft of sting sheath opening 



to exterior from prolongation of body-cavity (be) con- 

 tained in each. 



pp, gelatinous layer secreted upon inner surface of ventric- 



ular epithelium. 



qq, food contents of alimentary canal. 



rr, cells of ventricular epithelium apparently forming the
